text: We present experimentally derived potential curves 1?and spin-orbit interaction
functions for the strongly perturbed AΣu+ 3?and bΠu states of the cesium dimer.
The results are based on data from several sources. Laser-induced fluorescence
Fourier transform spectroscopy (LIF FTS) was used some time ago in the Laboratoire
Aimé Cotton primarily to study the XΣg+ state. More recent work at Tsinghua University
provides information from moderate 3?resolution spectroscopy on the lowest levels
of the bΠ0u± state as well as additional high-resolution data. From Innsbruck
University, we have precision data obtained with cold Cs2 molecules. Recent data
from Temple University was obtained using the optical-optical double resonance
polarization spectroscopy technique, and finally, a group at the University of
Latvia has added additional LIF FTS data. In the Hamiltonian matrix, we have used
analytic potentials (the expanded Morse oscillator form) with both finite-difference
(FD) coupled-channel and discrete variable representation (DVR) calculations of
the term values. Fitted diagonal and off-diagonal spin-orbit functions are obtained
and compared with ab initio results from Temple and Moscow State universities.

text: We demonstrate the temporal Talbot effect for trapped matter waves using ultracold
atoms in an optical lattice. We investigate the phase evolution of an array of
essentially non-interacting matter waves and observe matter-wave collapse and
revival in the form of a Talbot interference pattern. By using long expansion
times, we image momentum space with sub-recoil resolution, allowing us to observe
fractional Talbot fringes up to tenth order.

text: The present paper aims at finding optimal parameters for trapping of Cs 2
molecules in optical lattices, with the perspective of creating a quantum degenerate
gas of ground-state molecules. We have calculated dynamic polarizabilities of
Cs 2 molecules subject to an oscillating electric field, using accurate potential
curves and electronic transition dipole moments. We show that for some particular
wavelengths of the optical lattice, called "magic wavelengths", the
polarizability of the ground-state molecules is equal to the one of a Feshbach
molecule. As the creation of the sample of ground-state molecules relies on an
adiabatic population transfer from weakly-bound molecules created on a Feshbach
resonance, such a coincidence ensures that both the initial and final states are
favorably trapped by the lattice light, allowing optimized transfer in agreement
with the experimental observation.

text: We perform precision measurements on a Mott-insulator quantum state of ultracold
atoms with tunable interactions. We probe the dependence of the superfluid-to-Mott-insulator
transition on the interaction strength and explore the limits of the standard
Bose-Hubbard model description. By tuning the on-site interaction energies to
values comparable to the interband separation, we are able to quantitatively measure
number-dependent shifts in the excitation spectrum caused by effective multibody
interactions.

text: We investigate local three-body correlations for bosonic particles in three
dimensions and one dimension as a function of the interaction strength. The three-body
correlation function g(3) is determined by measuring the three-body recombination
rate in an ultracold gas of Cs atoms. In three dimensions, we measure the dependence
of g(3) on the gas parameter in a BEC, finding good agreement with the theoretical
prediction accounting for beyond-mean-field effects. In one dimension, we observe
a reduction of g( 3) by several orders of magnitude upon increasing interactions
from the weakly interacting BEC to the strongly interacting Tonks-Girardeau regime,
in good agreement with predictions from the Lieb-Liniger model for all strengths
of interaction.

text: Synchronous distributed algorithms are easier to design and prove correct
than algorithms that tolerate asynchrony. Yet, in the real world, networks experience
asynchrony and other timing anomalies. In this paper, we address the question
of how to efficiently transform an algorithm that relies on synchronization into
an algorithm that tolerates asynchronous executions. We introduce a transformation
technique from synchronous algorithms to indulgent algorithms [1], which induces
only a constant overhead in terms of time complexity in well-behaved executions.
Our technique is based on a new abstraction we call an asynchrony detector, which
the participating processes implement collectively. The resulting transformation
works for a large class of colorless tasks, including consensus and set agreement.
Interestingly, we also show that our technique is relevant for colored tasks,
by applying it to the renaming problem, to obtain the first indulgent renaming
algorithm.

text: 'We study the complexity of renaming, a fundamental problem in distributed
computing in which a set of processes need to pick distinct names from a given
namespace. We prove an individual lower bound of Ω(k) process steps for deterministic
renaming into any namespace of size sub-exponential in k, where k is the number
of participants. This bound is tight: it draws an exponential separation between
deterministic and randomized solutions, and implies new tight bounds for deterministic
fetch-and-increment registers, queues and stacks. The proof of the bound is interesting
in its own right, for it relies on the first reduction from renaming to another
fundamental problem in distributed computing: mutual exclusion. We complement
our individual bound with a global lower bound of Ω(k log (k/c)) on the total
step complexity of renaming into a namespace of size ck, for any c ≥ 1. This applies
to randomized algorithms against a strong adversary, and helps derive new global
lower bounds for randomized approximate counter and fetch-and-increment implementations,
all tight within logarithmic factors.'

text: We give two new randomized algorithms for strong renaming, both of which work
against an adaptive adversary in asynchronous shared memory. The first uses repeated
sampling over a sequence of arrays of decreasing size to assign unique names to
each of n processes with step complexity O(log3 n). The second transforms any
sorting network into a strong adaptive renaming protocol, with an expected cost
equal to the depth of the sorting network. Using an AKS sorting network, this
gives a strong adaptive renaming algorithm with step complexity O(log k), where
k is the contention in the current execution. We show this to be optimal based
on a classic lower bound of Jayanti. We also show that any such strong renaming
protocol can be used to build a monotone-consistent counter with logarithmic step
complexity (at the cost of adding a max register) or a linearizable fetch-and-increment
register (at the cost of increasing the step complexity by a logarithmic factor).

text: During assembly of the Drosophila olfactory circuit, projection neuron (PN)
dendrites prepattern the developing antennal lobe before the arrival of axons
from their presynaptic partners, the adult olfactory receptor neurons (ORNs).
We previously found that levels of transmembrane Semaphorin-1a, which acts as
a receptor, instruct PN dendrite targeting along the dorsolateral-ventromedial
axis. Here we show that two secreted semaphorins, Sema-2a and Sema-2b, provide
spatial cues for PN dendrite targeting. Sema-2a and Sema-2b proteins are distributed
in gradients opposing the Sema-1a protein gradient, and Sema-1a binds to Sema-2a-expressing
cells. In Sema-2a and Sema-2b double mutants, PN dendrites that normally target
dorsolaterally in the antennal lobe mistarget ventromedially, phenocopying cell-autonomous
Sema-1a removal from these PNs. Cell ablation, cell-specific knockdown, and rescue
experiments indicate that secreted semaphorins from degenerating larval ORN axons
direct dendrite targeting. Thus, a degenerating brain structure instructs the
wiring of a developing circuit through the repulsive action of secreted semaphorins.

text: Longitudinal axon fascicles within the Drosophila embryonic CNS provide connections
between body segments and are required for coordinated neural signaling along
the anterior-posterior axis. We show here that establishment of select CNS longitudinal
tracts and formation of precise mechanosensory afferent innervation to the same
CNS region are coordinately regulated by the secreted semaphorins Sema-2a and
Sema-2b. Both Sema-2a and Sema-2b utilize the same neuronal receptor, plexin B
(PlexB), but serve distinct guidance functions. Localized Sema-2b attraction promotes
the initial assembly of a subset of CNS longitudinal projections and subsequent
targeting of chordotonal sensory afferent axons to these same longitudinal connectives,
whereas broader Sema-2a repulsion serves to prevent aberrant innervation. In the
absence of Sema-2b or PlexB, chordotonal afferent connectivity within the CNS
is severely disrupted, resulting in specific larval behavioral deficits. These
results reveal that distinct semaphorin-mediated guidance functions converge at
PlexB and are critical for functional neural circuit assembly.

text: Chandelier (axoaxonic) cells (ChCs) are a distinct group of GABAergic interneurons
that innervate the axon initial segments of pyramidal cells. However, their circuit
role and the function of their clearly defined anatomical specificity remain unclear.
Recent work has demonstrated that chandelier cells can produce depolarizing GABAergic
PSPs, occasionally driving postsynaptic targets to spike. On the other hand, other
work suggests that ChCs are hyperpolarizing and may have an inhibitory role. These
disparate functional effects may reflect heterogeneity among ChCs. Here, using
brain slices from transgenic mouse strains, we first demonstrate that, across
different neocortical areas and genetic backgrounds, upper Layer 2/3 ChCs belong
to a single electrophysiologically and morphologically defined population, extensively
sampling Layer 1 inputs with asymmetric dendrites. Consistent with being a single
cell type, we find electrical coupling between ChCs. We then investigate the effect
of chandelier cell activation on pyramidal neuron spiking in several conditions,
ranging from the resting membrane potential to stimuli designed to approximate
in vivo membrane potential dynamics. We find that under quiescent conditions,
chandelier cells are capable of both promoting and inhibiting spike generation,
depending on the postsynaptic membrane potential. However, during in vivo-like
membrane potential fluctuations, the dominant postsynaptic effect was a strong
inhibition. Thus, neocortical chandelier cells, even from within a homogeneous
population, appear to play a dual role in the circuit, helping to activate quiescent
pyramidal neurons, while at the same time inhibiting active ones.

text: Cortical neurons receive balanced excitatory and inhibitory synaptic currents.
Such a balance could be established and maintained in an experience-dependent
manner by synaptic plasticity at inhibitory synapses. We show that this mechanism
provides an explanation for the sparse firing patterns observed in response to
natural stimuli and fits well with a recently observed interaction of excitatory
and inhibitory receptive field plasticity. The introduction of inhibitory plasticity
in suitable recurrent networks provides a homeostatic mechanism that leads to
asynchronous irregular network states. Further, it can accommodate synaptic memories
with activity patterns that become indiscernible from the background state but
can be reactivated by external stimuli. Our results suggest an essential role
of inhibitory plasticity in the formation and maintenance of functional cortical
circuitry.

text: The accurate experimental determination of dipolar-coupling constants for
one-bond heteronuclear dipolar couplings in solids is a key for the quantification
of the amplitudes of motional processes. Averaging of the dipolar coupling reports
on motions on time scales up to the inverse of the coupling constant, in our case
tens of microseconds. Combining dipolar-coupling derived order parameters that
characterize the amplitudes of the motion with relaxation data leads to a more
precise characterization of the dynamical parameters and helps to disentangle
the amplitudes and the time scales of the motional processes, which impact relaxation
rates in a highly correlated way. Here. we describe and characterize an improved
experimental protocol – based on REDOR – to measure these couplings in perdeuterated
proteins with a reduced sensitivity to experimental missettings. Because such
effects are presently the dominant source of systematic errors in experimental
dipolar-coupling measurements, these compensated experiments should help to significantly
improve the precision of such data. A detailed comparison with other commonly
used pulse sequences (T-MREV, phase-inverted CP,R18 5/2, and R18 7/1) is provided.

text: Despite the importance of protein fibrils in the context of conformational
diseases, information on their structure is still sparse. Hydrogen/deuterium exchange
measurements of backbone amide protons allow the identification hydrogen-bonding
patterns and reveal pertinent information on the amyloid β-sheet architecture.
However, they provide only little information on the identity of residues exposed
to solvent or buried inside the fibril core. NMR spectroscopy is a potent method
for identifying solvent-accessible residues in proteins via observation of polarization
transfer between chemically exchanging side-chain protons and water protons. We
show here that the combined use of highly deuterated samples and fast magic-angle
spinning greatly attenuates unwanted spin diffusion and allows identification
of polarization exchange with the solvent in a site-specific manner. We apply
this measurement protocol to HET-s(218–289) prion fibrils under different conditions
(including physiological pH, where protofibrils assemble together into thicker
fibrils) and demonstrate that each protofibril of HET-s(218–289), is surrounded
by water, thus excluding the existence of extended dry interfibril contacts. We
also show that exchangeable side-chain protons inside the hydrophobic core of
HET-s(218–289) do not exchange over time intervals of weeks to months. The experiments
proposed in this study can provide insight into the detailed structural features
of amyloid fibrils in general.

text: The classical principle of least action says that orbits of mechanical systems
extremize action; an important subclass are those orbits that minimize action.
In this paper we utilize this principle along with Aubry-Mather theory to construct
(Birkhoff) regions of instability for a certain three-body problem, given by a
Hamiltonian system of 2 degrees of freedom. We believe that these methods can
be applied to construct instability regions for a variety of Hamiltonian systems
with 2 degrees of freedom. The Hamiltonian model we consider describes dynamics
of a Sun-Jupiter-comet system, and under some simplifying assumptions, we show
the existence of instabilities for the orbit of the comet. In particular, we show
that a comet which starts close to an orbit in the shape of an ellipse of eccentricity
e=0.66 can increase in eccentricity up to e=0.96. In the sequels to this paper,
we extend the result to beyond e=1 and show the existence of ejection orbits.
Such orbits are initially well within the range of our solar system. This might
give an indication of why most objects rotating around the Sun in our solar system
have relatively low eccentricity.
