text: The nonaqueous rechargeable lithium–O2 battery containing an alkyl carbonate
electrolyte discharges by formation of C3H6(OCO2Li)2, Li2CO3, HCO2Li, CH3CO2Li,
CO2, and H2O at the cathode, due to electrolyte decomposition. Charging involves
oxidation of C3H6(OCO2Li)2, Li2CO3, HCO2Li, CH3CO2Li accompanied by CO2 and H2O
evolution. Mechanisms are proposed for the reactions on discharge and charge.
The different pathways for discharge and charge are consistent with the widely
observed voltage gap in Li–O2 cells. Oxidation of C3H6(OCO2Li)2 involves terminal
carbonate groups leaving behind the OC3H6O moiety that reacts to form a thick
gel on the Li anode. Li2CO3, HCO2Li, CH3CO2Li, and C3H6(OCO2Li)2 accumulate in
the cathode on cycling correlating with capacity fading and cell failure. The
latter is compounded by continuous consumption of the electrolyte on each discharge.

text: Lithium-metal oxides with a high formal Li2O content, such as Li5FeO4 (5Li2O•Fe2O3)
and a Li2MnO3•LiFeO2 composite ({Li2O•MnO2}•{Li2O•Fe2O3}) have been explored as
electrocatalysts for primary and rechargeable Li-O2 cells. Activation occurs predominantly
by Li2O removal, either electrochemically or chemically by acid-treatment. Superior
electrochemical behavior is obtained if activation occurs by acid-treatment; Li2MnO3•LiFeO2
catalysts provide 2516 mAh/g (carbon) corresponding to 931 mAh/g (electrocatalyst
+ carbon) during the initial discharge. The reaction is reasonably reversible
during the early cycles. The approach has implications for designing electrocatalysts
that participate through electrochemical Li2O extraction/reformation reactions,
offering exceptionally high capacities.

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 emergence of differences in the arrangement of cells is the first step
towards the establishment of many organs. Understanding this process is limited
by the lack of systematic characterization of epithelial organisation. Here we
apply network theory at the scale of individual cells to uncover patterns in cell-to-cell
contacts that govern epithelial organisation. We provide an objective characterisation
of epithelia using network representation, where cells are nodes and cell contacts
are links. The features of individual cells, together with attributes of the cellular
network, produce a defining signature that distinguishes epithelia from different
organs, species, developmental stages and genetic conditions. The approach permits
characterization, quantification and classification of normal and perturbed epithelia,
and establishes a framework for understanding molecular mechanisms that underpin
the architecture of complex tissues.

text: Morphogens, such as Decapentaplegic (Dpp) in the fly imaginal discs, form
graded concentration profiles that control patterning and growth of developing
organs. In the imaginal discs, proliferative growth is homogeneous in space, posing
the conundrum of how morphogen concentration gradients could control position-independent
growth. To understand the mechanism of proliferation control by the Dpp gradient,
we quantified Dpp concentration and signaling levels during wing disc growth.
Both Dpp concentration and signaling gradients scale with tissue size during development.
On average, cells divide when Dpp signaling levels have increased by 50%. Our
observations are consistent with a growth control mechanism based on temporal
changes of cellular morphogen signaling levels. For a scaling gradient, this mechanism
generates position-independent growth rates.

text: Spin-selective tunneling of holes in SiGe nanocrystals contacted by normal-metal
leads is reported. The spin selectivity arises from an interplay of the orbital
effect of the magnetic field with the strong spin-orbit interaction present in
the valence band of the semiconductor. We demonstrate both experimentally and
theoretically that spin-selective tunneling in semiconductor nanostructures can
be achieved without the use of ferromagnetic contacts. The reported effect, which
relies on mixing the light and heavy holes, should be observable in a broad class
of quantum-dot systems formed in semiconductors with a degenerate valence band.

text: At optical frequencies the radiation produced by a source, such as a laser,
a black body or a single-photon emitter, is frequently characterized by analysing
the temporal correlations of emitted photons using single-photon counters. At
microwave frequencies, however, there are no efficient single-photon counters
yet. Instead, well-developed linear amplifiers allow for efficient measurement
of the amplitude of an electromagnetic field. Here, we demonstrate first- and
second-order correlation function measurements of a pulsed microwave-frequency
single-photon source integrated on the same chip with a 50/50 beam splitter followed
by linear amplifiers and quadrature amplitude detectors. We clearly observe single-photon
coherence in first-order and photon antibunching in second-order correlation function
measurements of the propagating fields.

text: Superconducting circuits have been successfully established as systems to
prepare and investigate microwave light fields at the quantum level. In contrast
to optical experiments where light is detected using photon counters, microwaves
are usually measured with well developed linear amplifiers. This makes measurements
of correlation functions - one of the important tools in optics - harder to achieve
because they traditionally rely on photon counters and beam splitters. Here, we
demonstrate a system where we can prepare on demand single microwave photons in
a cavity and detect them at the two outputs of the cavity using linear amplifiers.
Together with efficient data processing, this allows us to measure different observables
of the cavity photons, including the first-order correlation function. Using these
techniques we demonstrate cooling of a thermal background field in the cavity.

text: A wide range of experiments studying microwave photons localized in superconducting
cavities have made important contributions to our understanding of the quantum
properties of radiation. Propagating microwave photons, however, have so far been
studied much less intensely. Here we present measurements in which we reconstruct
the quantum state of itinerant single photon Fock states and their superposition
with the vacuum by analyzing moments of the measured amplitude distribution up
to fourth order. Using linear amplifiers and quadrature amplitude detectors, we
have developed efficient methods to separate the detected single photon signal
from the noise added by the amplifier. From our measurement data we have also
reconstructed the corresponding Wigner function.

text: Creating a train of single photons and monitoring its propagation and interaction
is challenging in most physical systems, as photons generally interact very weakly
with other systems. However, when confining microwave frequency photons in a transmission
line resonator, effective photon-photon interactions can be mediated by qubits
embedded in the resonator. Here, we observe the phenomenon of photon blockade
through second-order correlation function measurements. The experiments clearly
demonstrate antibunching in a continuously pumped source of single microwave photons
measured by using microwave beam splitters, linear amplifiers, and quadrature
amplitude detectors. We also investigate resonance fluorescence and Rayleigh scattering
in Mollow-triplet-like spectra.

text: Continuous variable entanglement between two modes of a radiation field is
usually studied at optical frequencies. Here we demonstrate experiments that show
the entanglement between microwave photons of different energy in a broadband
squeezed beam. We use a Josephson parametric amplifier to generate the two-mode
correlated state and detect all four quadrature components simultaneously in a
two-channel heterodyne setup using amplitude detectors. Analyzing two-dimensional
phase space histograms for all possible pairs of quadratures allows us to determine
the full covariance matrix, which is in good agreement with the one expected for
a two-mode squeezed state.
