article, A brief review of the recent progress of superconductor

development of the field, including rapid progress of the low-T, Josephson
junction technology and recent invention of several important devices. In
the near future, these developments promise the advent of several
outstanding electronic devices which would be of practical value, despite
the need for helium cooling. Against this background, introduction of the
high-T, superconductors in the foreseeable future will probably be
restricted to the few simplest electronic devices and components.

Phys, new frequency modulation (FM) technique has been demonstrated which
ennances the sensitivity of attractive mode force microscopy by an order
of magnitude or more. Increased sensitivity is made possible by operating
in a moderate vacuum ( less than 10 - 5 Torr), which increases the Q of
the vibrating cantilever. In the FM technique, the cantilever serves as
the frequency determining element of an oscillator. Force gradients acting
on the cantilever cause instantaneous frequency modulation of the
oscillator output, which is demodulated with a FM detector. Unlike
conventional slope detection, the FM technique offers increased
sensitivity through increased Q without restricting system bandwidth.

199401 A variational method is used to
calculate the deflection and the fundamental and harmonic resonance
frequencies of commercial V-shaped and rectangular atomic force microscopy
cantilevers. The effective mass of V shaped cantilevers is roughly half
that calculated for the equivalent rectangular cantilevers. Damping by
environmental gases, including air, nitrogen, argon, and helium, affects
the frequency of maximum response and to a much greater degree the quality
factor Q. Helium has the lowest viscosity, resulting in the highest Q, and
thus provides the best sensitivity in noncontact force microscopy. Damping
in liquids is dominated by an increase in effective mass of the cantilever
due to an added mass of the liquid being dragged with that cantilever.

199601 We consider the effects of close coupling
between magnetic spin systems and oscillator detectors. The scaling of
present experiments using both mechanical and electrical oscillator
detectors for single-spin detection is examined. We show how nonlinear
interactions ignored in previous descriptions may dominate the detector
response in single-spin schemes using mechanical detectors. From a
generalized form of the coupled Bloch equations, the difference between
mechanical and electrical oscillator detection can be readily appreciated.
Numerical solution of the coupled system using reasonable experimental
parameters shows that complex dynamics may be observed in the single-spin
detection scheme when the detector and the spin system are strongly
coupled. The interpretation of spin system data obtained from the motion
of a mechanical oscillator will require understanding of these detector
effects. oscillator theory

microscopies need actuators to produce controlled displacements of
surfaces in the nanoscale range. Usually piezoelectric ceramics are used
for this function. In this article, we describe a magnetic way to produce
a similar movement without the use of high voltage. The position is
obtained with a precision lower than 10 pm in the range of a hundred
micrometers and a bandwidth of 1 kHz. All the parameters of this system
can be accurately and easily determined. The knowledge of an analytical
form of the transient response of the actuator makes the calibration of
the position sensor needless. The direct measurement of the position of
the magnet gives entirely reliable results. This actuator could be, for
example, applied to atomic force microscopy where a good precision in
displacement is required to get force/distance curves or surface images.

199701 The performance of a fiber-optic sensor and its

problem in the package design of a fiber-optic sensor. An intensity based
fiber-optic sensor that can be used as a refractive-index or displacement
sensor is considered as a case study in analyzing the effects of alignment
on the performance of a fiber-optic sensor. Alignability of this sensor
package is defined and calculated, taking into account the coupling
efficiency and effects of various misalignments. Guidelines for making the
package so that the fiber-optic sensor works more efficiently are

copy is in German, but the abstract translation is The probehead itself is
an all-in-one assembly and contains both the resonance circuit and the
components for tuning and matching to 50 Ohms impedance. The magnet
systems is made of two permanent magnets (Nd-Fe-B alloy, high density of
magnetic energy). They are built in a homemade mechanic frame to adjust
the homogeneity of the external magnetic field. The magnetic field
achieved with this setup is 0.35T (according to 14.9Mhz proton resonance
frequency) with a homogeneity of about 30ppm. We succesfully detected NMR
signals with this probe. Uses a sample N,N Dimethylacetamid which might
be why I noticed this paper, and also has the routine collection of Sidles

for broadband position measurement, I utilize the Caves-Milburn model for

illustrate the use of Kalman filtering to recover the SQL for estimating a
weak classical force that acts on a quantum mechanical test particle under
continuous observation. These derivations are intended to clarify the
interpretation of SQL's in the context of broadband quantum measurement,
with particular attention paid to the question of how it might be possible
to verify that a given laboratory measurement does indeed achieve
backaction-limited sensitivity. The method used to analyze force detection
may be extended to the case of weak classical forces with arbitrary time
dependence, including nonstationary and impulsive signals.

Classical atomic force microscopes use a soft cantilever spring to
convert the interaction between a tip and a surface into a displacement.
This leads to indirect force measurement and instability in the case of
attractive forces. We have developed a new kind of force sensor to
overcome these limitations. The principle is to place a tip glued on a
small magnet in levitation in a magnetic field. A servo-loop ensures the
stability of the equilibrium in the vertical direction and allows the
measurement of forces. It is monitored by an optical sensor that measures
continuously the actual position of the tip with a sensitivity of 10 pm.
With such a device it is possible to obtain the van der Waals attraction
up to the molecular contact without jump. A digital signal processing
board stops the approach of the tip just before contact to prevent any
deterioration of the surface during the measurement. This allows images of
soft and brittle surfaces, such as a micro-filtration membrane.

Genolet1999 199901 with Vettiger
at IBM, and someone at Novartis, A new probe made entirely of plastic
material has been developed for scanning probe microscopy. Using a polymer
for the cantilever facilitates the realization of mechanical properties
that are difficult to achieve with classical silicon technology. The new
cantilever and tip presented here are made of an epoxy-based photoplastic.
The fabrication process is a simple batch process in which the integrated
tip and the lever are defined in one photolithography step. The simplicity
of the fabrication step, the use of a polymer as material, and the ability
to reuse the silicon mold lead to a soft low-cost probe for scanning force
microscopy. Imaging soft condensed matter with photoplastic levers, which
uses laser beam deflection sensing, exhibits a resolution that compares
well with that of commercially available silicon cantilevers.

Imry1999 199901 with Landauer at the
IBM Watson Center, Electric current flow, in transport theory, has usually
been viewed as the response to an applied electric field. Alternatively,
current flow can be viewed as a consequence of the injection of carriers
at contacts and their probability of reaching the other end. This approach
has proven to be particularly useful for the small samples made by modern
microelectronic techniques. The approach, some of its results, and related
issues are described, but without an attempt to cover all the active
subtopics in this field. electron theory

signal, Equations are derived which describe the time evolution of the

closed form expression for the characteristic function is obtained for the
tuned case and the predicted joint statistics and correlation properties
are reviewed in the context of earlier results. Low order correlation
properties for the more general detuned case are calculated. It is shown
that the stationary single interval statistics can be generated by a
random phasor moving in a space of fractional dimensions and that a simple
transform of variable leads to distributions which are stable in this
space. qm signals

199908 obituary for Landauer, It is well known that
scientific progress requires intellect. Less advertised is science's need
for conscience. Intellect creates new ideas; conscience examines them for
consistency and correctness. In other words, a scientific field requires
not only head but heart as well. Rolf Landauer was both head and heart to
the field of physics of information. He died of cancer on 27 April this
year at the age of 72. Landauer based his research on a simple rule:
information is physical. That is, information is registered by physical
systems such as strands of DNA, neurons and transistors; in turn, the ways
in which systems such as cells, brains and computers can process
information is governed by the laws of physics.

IEEE, Polyspectra are related to Fourier transforms of moment or
cumulant functions of any order of random signals. They play an important
role in many problems of signal analysis and processing. However, there
are only a few statistical models giving explicitly the expression of
polyspectra. Ordered signals are signals for which the explicit expression
of the moment functions requires that the time instants appearing in these
moments are put in an increasing order. There are many examples of such
signals, the best known being the random telegraph signal constructed from
a Poisson process. Some of these examples are presented and analyzed. The
origin of the ordering structure is related with the point that real time
is an oriented variable making a difference between past and future. This
especially appears in Markov processes. The calculation of polyspectra is
difficult because ordering is not adapted to Fourier analysis. By an
appropriate grouping of various terms, the explicit expression of spectral
moment functions is obtained. It shows in particular that many ordered
signals present a normal density on the normal manifolds of the frequency
domain and another contribution on the stationary manifold that is
explicitly calculated. The analysis of the structure of this expression
allows us to discuss some relationships with normal distribution, central
limit theorem, and time reversibility. information

200001 We discuss the stability of the tip motion in
dynamic atomic force microscopy. A nonlinear dynamics analysis shows that
the tip's phase space is divided in two basins of attraction. A phase
space diagram dominated by either basin of attraction implies a stable
motion while a substantial contribution from both basins is associated
with instabilities. Because the dominance of a given basin of attraction
depends on the tip surface interaction potential and separation, stable
and unstable motions are intrinsic features of an oscillating tip near or
in intermittent contact with a surface. afm

thermoelastic damping as a fundamental dissipation mechanism for
small-scale mechanical resonators is evaluated in light of recent efforts
to design high-Q micrometer- and nanometer scale electromechanical
systems. The equations of linear thermoelasticity are used to give a
simple derivation for thermoelastic damping of small flexural vibrations
in thin beams. It is shown that Zener's well-known approximation by a
Lorentzian with a single thermal relaxation time slightly deviates from
the exact expression. cantilever

monodisperse nanocrystalline cobalt (Co) particles in non-polar colloidal
dispersions, large areas of symmetric multi-dimensional structures were
created using magnetophoretic deposition (MPD). To overcome the van der
Waals and magnetic dipole-dipole interactions, the particles were
stabilized with hydrophobic amines, phosphines, carboxylates and/or
polymers. Depending on the preparation parameters, our particles had
either bcc or E-Co crystalline structures. Using MPD with magnetic fields
up to 1 T, it was possible to create two-dimensional (2-D) arrays of
near-perfect symmetry up to 1 um^2 in size on various substrates, e.g.
carbon-coated copper grids, silicon, or glass. Growth of the 2-D crystal
was shown to be dependent on the direction of the applied external
magnetic field. Three-dimensional (3-D) crystals could be created by
increasing the magnetic field strength up to 6 T. crystal

Finding a means to generate, control and use spin-polarized currents
represents an important challenge for spin-based electronics, or
'spintronics'. Spin currents and the associated phenomenon of spin
accumulation can be realized by driving a current from a ferromagnetic
electrode into a non-magnetic metal or semiconductor. This was first
demonstrated over 15 years ago in a spin injection experiment4 on a single
crystal aluminium bar at temperatures below 77 K. Recent experiments5+-8
have demonstrated successful optical detection of spin injection in
semiconductors, using either optical injection by circularly polarized
light or electrical injection from a magnetic semiconductor.However, it
has not been possible to achieve fully electrical spin injection and
detection at room temperature. Here we report room-temperature electrical
injection and detection of spin currents and observe spin accumulation in
an all-metal lateral mesoscopic spin valve, where ferromagnetic electrodes
are used to drive a spin-polarized current into crossed copper strips. We
anticipate that larger signals should be obtainable by optimizing the
choice of materials and device geometry. spin

sponsor's research interest in superconductor properties, High-Tc oxides
are intrinsically inhomogeneous materials. The density of states is
evaluated for such an inhomogeneous system, and it displays a gap
structure above Tc res pseudogap. Thus, the pseudogap phenomenon can be
caused by an inhomogeneity of the metallic phase. As a result, the
critical temperature is spatially dependent. Various types of nonuniform
structure are described inhomogeneous carrier distribution, nonuniform
distribution of pair breakers!. The transition to a dissipationless state
(R=0) corresponds to the percolation threshold.

An atomic force microscope for nanocantilevers measuring
from a few 100 nm to a few mm in length was implemented. The natural
frequencies of the nanocantilevers lie in the range of 1 MHz to 1 GHz, and
optical detection schemes adapted to their size and frequency range was
selected. A helium neon laser with a beat frequency of 890 MHz was used as
the laser source. The beat was shifted to 1090 MHz by an
acousto-optical-modulator, and used as the carrier for heterodyne laser
Doppler measurement. This enabled velocity measurement up to around 100
MHz. The probe beam of the Doppler interferometer was guided to the
nanocantilever by a single mode polarization-maintaining optical fiber
terminated by a collimating lens, a quarter wave plate, and a focusing
lens. Reflected light was collected by the same optics and mixed with the

Phys Rev B, We have studied theoretically the basic
operation of a quantum feedback loop designed to maintain a desired phase
of quantum coherent oscillations in a single solid-state qubit. The degree
of oscillations synchronization with external harmonic signal is
calculated as a function of feedback strength, taking into account
available bandwidth and coupling to environment. The feedback can
efficiently suppress the dephasing of oscillations if the qubit coupling
to the detector is stronger than the coupling to the environment.

propose a displacement sensing scheme for rf mechanical resonators made
from GaAs, based on detecting the piezoelectrically induced charge. By
using a single-electron transistor to detect the charge, we calculate that
a significantly higher displacement sensitivity can be achieved than by
using capacitive displacement sensing, primarily due to the strong
piezoelectric coupling strength. We estimate a displacement sensitivity of
order 10^-17 m/Hz^1/2 for a 1 GHz GaAs resonator. Our model solves the
coupled electromechanical response self-consistently, including the
effects of both dissipative and reactive electronic circuit elements on
the resonator behavior. piezo transistor

State Observability and Measurement, We consider the problem of
determining the state of a quantum system given one or more readings of
the expectation value of an observable. The system is assumed to be a
finite dimensional quantum control system for which we can influence the
dynamics by generating all the unitary evolutions in a Lie group. We
investigate to what extent, by an appropriate sequence of evolutions and
measurements, we can obtain information on the initial state of the
system. We present a system theoretic viewpoint of this problem in that we
study the observability of the system. qm

controllability, observability and parameter identification of these
systems. We give conditions for controllability and observability and
characterize the classes of equivalent models which have the same
input-output behavior. The analysis is motivated by the recent interest in
three level systems in quantum information theory and quantum cryptography
as well as by the problem of modeling molecular magnets as spin networks.

200301 Continuous observation of a quantum system yields a
measurement record that faithfully reproduces the classically predicted
trajectory provided that the measurement is sufficiently strong to
localize the state in phase space but weak enough that quantum backaction
noise is negligible. We investigate the conditions under which classical
dynamics emerges, via continuous position measurement, for a particle
moving in a harmonic well with its position coupled to internal spin. As a
consequence of this coupling we find that classical dynamics emerges only
when the position and spin actions are both large compared. These
conditions are quantified by placing bounds on the size of the covariance
matrix which describes the delocalized quantum coherence over extended
regions of phase space. From this result it follows that a mixed
quantum-classical regime (where one subsystem can be treated classically
and the other not) does not exist for a continuously observed spin 1/2
particle. When the conditions for classicallity are satisfied (in the
large-spin limit), the quantum trajectories reproduce both the classical
periodic orbits as well as the classically chaotic phase space regions. As
a quantitative test of this convergence we compute the largest Lyapunov
exponent directly from the measured quantum trajectories and show that it
agrees with the classical value. qm

Part of a review collection introduced by Reudi Abersold of

hence bioinformatics is important. They are developing the Open
Microscopy Environment (OME) to consistently record the varieties of data
generated by different sample preparations, different imaging devices and
methodologies, and different image deconvolution. XML is used to tag each
piece of data, creating files out of a central, relational database.
Modules representing linked investigative paths independently communicate
with the database to generate XML files whose semantic content they hope
will be complete and founded in consistency. Data analysis and
interpretation are challenges, but the solution by informatics is equally
a solution by community. This solution outlines the many solutions that
will continue to emerge as a listable property of this effort, and one we
prospectively hope has enduring value. biology

particular, when the error model is restricted to one, perfectly measured,

200401 We study arrays of mechanical oscillators in the
quantum domain and demonstrate how the motions of distant oscillators can
be entangled without the need for control of individual oscillators and
without a direct interaction between them. These oscillators are thought
of as being members of an array of nanoelectromechanical resonators with a
voltage being applicable between neighboring resonators. Sudden
nonadiabatic switching of the interaction results in a squeezing of the
states of the mechanical oscillators, leading to an entanglement transport
in chains of mechanical oscillators.We discuss spatial dimensions, Q
factors, temperatures and decoherence sources in some detail, and find a
distinct robustness of the entanglement in the canonical coordinates in
such a scheme.We also briefly discuss the challenging aspect of detection

describes a surface micromachined cantilever beam-based resonator for

technique of merged epitaxial lateral overgrowth (MELO) and chemical
mechanical polishing (CMP) to fabricate thin, low stress, single-crystal
silicon cantilever beams. The vibration spectra of the cantilever beams,
excited by thermal and ambient noise, was measured in air using a
Dimension 3100 Series scanning probe microscope (SPM), and in certain
cases, a Polytec MSV300 laser Doppler vibrometer. The sensors were used to
detect the mass of Listeria innocua bacteria by applying increasing
concentration of bacteria suspension on the same cantilever beams and
measuring the resonant frequency changes in air. Cantilever beams were
also used to detect the mass of proteins such as Bovine Serum Albumin
(BSA) and antibodies for Listeria that were attached to the cantilever's
surfaces by physical adsorption; following which they were used to capture
and detect the mass of the bacterial cells on the functionalized
cantilever beam surfaces. The effects of critical point drying of the
proteins were evaluated and the results indicate that the functionality of
the antibodies was not reduced once rehydrated after critical point
drying. The developed biosensor is capable of rapid and ultrasensitive
detection of bacteria and promises significant potential for the
enhancement of microbiological research and diagnostics.

We have used a resonating mechanical cantilever to detect immunospecific
binding of viruses, captured from liquid. As a model virus, we used a
nonpathogenic insect baculovirus to test the ability to specifically bind
and detect small numbers of virus particles. Arrays of surface
micromachined, antibody-coated polycrystalline silicon nanomechanical
cantilever beams were used to detect binding from various concentrations
of baculoviruses in a buffer solution. Because of their small mass, the
0.5 um x 6 um cantilevers have mass sensitivities on the order of 10-19
gHz, enabling the detection of an immobilized AcV1 antibody monolayer
corresponding to a mass of about 3x10-15 g. With these devices, we can
detect the mass of single-virus particles bound to the cantilever.
Resonant frequency shift resulting from the adsorbed mass of the virus
particles distinguished solutions of virus concentrations varying between
10^5 and 10^7 pfu/ ml. Control experiments using buffer solutions without
baculovirus showed small amounts less than 50 attograms of nonspecific
adsorption to the antibody layer. / cantilever

Jahnchke2004 200401 In scanning probe
microscopy, it is critical to maintain small probe sample separations for
high resolution imaging. Quartz crystal tuning forks are typically used
for detecting shear forces in near-field scanning optical microscopy and
normal forces in other atomic force-related microscopies. In this article
we compare several tuning fork based detection schemes to determine which
solution gives the best signal to noise ratio. The high impedance and low
signals produced by the tuning fork necessitate care in selection of an
appropriate preamplifier. We find that a carefully guarded voltage
preamplifier sensing a mechanically driven tuning fork performs the best,
but an electrically driven fork with a current preamplifier offers simpler
construction with only 25% lower signal to noise ratio on average.

Peres200401 200401 with Terno, This article
discusses the intimate relationship between quantum mechanics, information
theory, and relativity theory. Taken together these are the foundations of
present-day theoretical physics, and their interrelationship is an
essential part of the theory. The acquisition of information from a
quantum system by an observer occurs at the interface of classical and
quantum physics. The authors review the essential tools needed to describe
this interface, i.e., Kraus matrices and positive-operator-valued
measures. They then discuss how special relativity imposes severe
restrictions on the transfer of information between distant systems and
the implications of the fact that quantum entropy is not a
Lorentz-covariant concept. This leads to a discussion of how it comes
about that Lorentz transformations of reduced density matrices for
entangled systems may not be completely positive maps. Quantum field
theory is, of course, necessary for a consistent description of
interactions. Its structure implies a fundamental tradeoff between
detector reliability and localizability. Moreover, general relativity
produces new and counterintuitive effects, particularly when black holes
(or, more generally, event horizons) are involved. In this more general
context the authors discuss how most of the current concepts in quantum
information theory may require a reassessment. qm

magnetic resonance force microscopy (MRFM), which showed recently the
sensitivity of order 10^100 spins [2]. The single-spin detection, however,
will require fundamental improvements of the method of MRFM. Further
approaches are based on the spin-dependent tunneling in mesoscopic devices

Pufall200406 200406 We show that a
spin-polarized dc current passing through a small magnetic element induces
two-state, random telegraph switching of the magnetization via the
spin-momentum transfer effect. The resistances of the states differ by up
to 50% of the change due to complete magnetization reversal. Fluctuations
are seen for a wide range of currents and magnetic fields, with rates that
can exceed 2 GHz, and involve collective motion of a large volume s10^4
nm^3 of spins. Switching rate trends with field and current indicate that
increasing temperature alone cannot explain the dynamics. The rates
approach a stochastic regime wherein dynamics are governed by both

The prototype millimeter-scale NMR spectrometer shows signal and noise
levels in agreement with the design principles.Wepresent 1H and 19F NMR in
both solid and liquid samples, including timedomain Fourier transform NMR
spectroscopy, multiple-pulse echoes, and heteronuclear J spectroscopy. By
measuring a 1H-19F J coupling, this last experiment accomplishes
chemically specific spectroscopy with force-detected NMR. In BOOMERANG, an
assembly of permanent magnets provides a homogeneous field throughout the
sample, while a harmonically suspended part of the assembly, a detector,
is mechanically driven by spin-dependent forces. By placing the sample in
a homogeneous field, signal dephasing by diffusion in a field gradient is
made negligible, enabling application to liquids, in contrast to other
force-detection methods. The design appears readily scalable to um-scale
samples where it should have sensitivity advantages over inductive
detection with microcoils and where it holds great promise for application
of magnetic resonance in biology, chemistry, physics, and surface science.
We briefly discuss extensions of the BOOMERANG method to the um and nm

nanowires are grown in a chemical beam epitaxy system and exhibit high
aspect ratios and high homogeneity in length and width. Investigations of
wire growth rate as a function of diameter, density, and time were
performed and the results indicate that 80% of the growth is due to In
species diffusing from the (111)B substrate surface. Furthermore, we have
established that the diffusion length on the 110 wire side surfaces

single-electron transistor (SET) coupled to a nanomechanical resonator is
calculated in the classical regime. Correlations between the charge on the
SET island and the position of the resonator give rise to a distinctive
noise spectrum which can be very different from that of the uncoupled SET.
The current noise spectrum of the coupled system contains peaks at both
the frequency of the resonator and double the resonator frequency, as well
as a strong enhancement of the noise at low frequencies. The heights of
the peaks are controlled by the strength of the coupling between the SET
and the resonator, the damping of the resonator, and the temperature of
the system. SET noise

Phys Rev A, The ability to perform a universal set of quantum
operations based solely on static resources and measurements presents us
with a striking viewpoint for thinking about quantum computation and its
powers. We consider the two major models for doing quantum computation by
measurements that have hitherto appeared in the literature and show that
they are conceptually closely related by demonstrating a systematic local
mapping between them. This way we effectively unify the two models,
showing that they make use of interchangeable primitives. With the tools
developed for this mapping, we then construct more resourceeffective
methods for performing computation within both models and propose schemes
for the construction of arbitrary graph states employing two qubit
measurements alone. qm measurement

with Wineland, Scalable quantum computation1 and communication
require error control to protect quantum information against unavoidable
noise. Quantum error correction protects information stored in two-level
quantum systems (qubits) by rectifying errors with operations conditioned
on the measurement outcomes. Error-correction protocols have been
implemented in nuclear magnetic resonance experiments, but the inherent
limitations of this technique prevent its application to quantum
information processing. Here we experimentally demonstrate quantum error
correction using three beryllium atomic-ion qubits confined to a linear,
multi-zone trap. An encoded one-qubit state is protected against spin-flip
errors by means of a three-qubit quantum error-correcting code. A primary
ion qubit is prepared in an initial state, which is then encoded into an
entangled state of three physical qubits (the primary and two ancilla
qubits).Errors are induced simultaneously in all qubits at various
rates.The encoded state is decoded back to the primary ion one-qubit
state, making error information available on the ancilla ions, which are
separated from the primary ion and measured. Finally,the primary qubit
state is corrected on the basis of the ancillae measurement outcome. We
verify error correction by comparingthe corrected final state to the
uncorrected state and to the initial state. In principle, the approach
enables a quantum state to be maintained by means of repeated error
correction, an importantstep towards scalable fault-tolerant quantum
computation using trapped ions. qm error

200412 Traditional language learning theory explores
an idealized interaction between a teacher and a learner. The teacher
provides sentences from a language, while the learner has to infer the
underlying grammar. Here, we study a new approach by considering a
population of individuals that learn from each other. There is no
designated teacher. We are inspired by the observation that children grow
up to speak the language of their peers, not of their parents. Our goal is
to characterize learning strategies that generate ``linguistic
coherence,'' which means that most individuals use the same language. We
model the resulting learning dynamics as a random walk of a population on
a graph. Each vertex represents a candidate language. We find that a
simple strategy using a certain aspiration level with the principle of
windstay, loseshift does extremely well: stay with your current language,
if at least three others use that language; otherwise, shift to an
adjacent language on the graph. This strategy guarantees linguistic
coherence on all nearly regular graphs, in the relevant limit where the
number of candidate languages is much greater than the population size.
Moreover, for many graphs, it is sufficient to have an aspiration level
demanding only two other individuals to use the same language.

resonant multiphonon excitations. Furthermore, we identify resonant

current flows through the other dot. Although locally, heat flows from

one-dimensional (1D) 1H NMR spectroscopy is routinely used to characterize
the folded state of protein targets and, thus, serves to guide subsequent
crystallization efforts and to identify proteins for NMR structure
determination. Here, we describe 1D 1H NMR screening of a group of 79
mouse homologue proteins, which correlates the NMR data with the outcome
of subsequent crystallization experiments and crystallographic structure
determination. Based on the 1D 1H NMR spectra, the proteins are classified
into four group. A-type proteins are candidates for structure
determination by NMR or crystallography; B-type are earmarked for
crystallography; C indicates folded globular proteins with broadened line
shapes; and D are nonglobular, unfolded polypeptides. The results obtained
from coarse- and fine-screen crystallization trials imply that only A- and
B-type proteins should be used for extensive crystallization trials in the
future, with C and D proteins subjected only to coarse-screen
crystallization trials. Of the presently studied 79 soluble protein
targets, 63 percent yielded A- or B-quality 1D 1H NMR spectra. Although
similar yields of crystallization hits were obtained for all four groups,
A to D, crystals from A- and B-type proteins diffracted on average to
significantly higher resolution than crystals produced from C- or D-type
proteins. Furthermore, the output of refined crystal structures from this

detectors serving as signal downmixers. The technique takes advantage of
the high strain sensitivity of semiconductor-based piezoresistors, while
overcoming the problem of rf signal attenuation due to a high source

between the detector and actuator circuits. We achieve thermomechanical
