text: Understanding and predicting the response of the hydrological cycle to climate
change is a major challenge with important societal implications. Much progress
has been made in understanding the response of global average precipitation by
considering the energy balances of the atmosphere and the surface1,2,3,4,5,6.
This energetic perspective reveals that changes in temperature, greenhouse gases,
aerosols, solar forcing and cloud feedbacks can all affect the global average
rate of precipitation5,7,8,9,10,11. Local precipitation changes have conventionally
been analysed using the water vapour budget, but here we show that the energetic
approach can be extended to local changes in precipitation by including changes
in horizontal energy transport. In simulations of twenty-first century climate
change, this energy transport accounts for much of the spatial variability in
precipitation change. We show that changes in radiative and surface sensible heat
fluxes are a guide to the local precipitation response over land and at large
scales, but not at small scales over the ocean, where cloud and water vapour radiative
feedbacks dampen the response. The energetic approach described here helps bridge
the gap between our understanding of global and regional precipitation changes.
It could be applied to better understand the response of regional precipitation
to different radiative forcings, including geo-engineering schemes, as well as
to understand the differences between the fast and slow responses of regional
precipitation to such forcings.

text: "A cloud-resolving model is used to investigate the effect of warming on high
percentiles of precipitation (precipitation extremes) in the idealized setting
of radiative-convective equilibrium. While this idealized setting does not allow
for several factors that influence precipitation in the tropics, it does allow
for an evaluation of the response of precipitation extremes to warming in simulations
with resolved rather than parameterized convection. The methodology developed
should also be applicable to less idealized simulations.\r\n\r\nModeled precipitation
extremes are found to increase in magnitude in response to an increase in sea
surface temperature. A dry static energy budget is used to relate the changes
in precipitation extremes to changes in atmospheric temperature, vertical velocity,
and precipitation efficiency. To first order, the changes in precipitation extremes
are captured by changes in the mean temperature structure of the atmosphere. Changes
in vertical velocities play a secondary role and tend to weaken the strength of
precipitation extremes, despite an intensification of updraft velocities in the
upper troposphere. The influence of changes in condensate transports on precipitation
extremes is quantified in terms of a precipitation efficiency; it does not change
greatly with warming.\r\n\r\nTropical precipitation extremes have previously been
found to increase at a greater fractional rate than the amount of atmospheric
water vapor in observations of present-day variability and in some climate model
simulations with parameterized convection. But the fractional increases in precipitation
extremes in the cloud-resolving simulations are comparable in magnitude to those
in surface water vapor concentrations (owing to a partial cancellation between
dynamical and thermodynamical changes), and are substantially less than the fractional
increases in column water vapor."

text: We study theoretically the shapes of a dividing epithelial monolayer of cells
lying on top of an elastic stroma. The negative tension created by cell division
provokes a buckling instability at a finite wave vector leading to the formation
of periodic arrays of villi and crypts. The instability is similar to the buckling
of a metallic plate under compression. We use the results to rationalize the various
structures of the intestinal lining observed in vivo. Taking into account the
coupling between cell division and local curvature, we obtain different patterns
of villi and crypts, which could explain the different morphologies of the small
intestine and the colon.

text: Collective cell migration in tissues occurs throughout embryonic development,
during wound healing, and in cancerous tumor invasion, yet most detailed knowledge
of cell migration comes from single-cell studies. As single cells migrate, the
shape of the cell body fluctuates dramatically through cyclic processes of extension,
adhesion, and retraction, accompanied by erratic changes in migration direction.
Within confluent cell layers, such subcellular motions must be coupled between
neighbors, yet the influence of these subcellular motions on collective migration
is not known. Here we study motion within a confluent epithelial cell sheet, simultaneously
measuring collective migration and subcellular motions, covering a broad range
of length scales, time scales, and cell densities. At large length scales and
time scales collective migration slows as cell density rises, yet the fastest
cells move in large, multicell groups whose scale grows with increasing cell density.
This behavior has an intriguing analogy to dynamic heterogeneities found in particulate
systems as they become more crowded and approach a glass transition. In addition
we find a diminishing self-diffusivity of short-wavelength motions within the
cell layer, and growing peaks in the vibrational density of states associated
with cooperative cell-shape fluctuations. Both of these observations are also
intriguingly reminiscent of a glass transition. Thus, these results provide a
broad and suggestive analogy between cell motion within a confluent layer and
the dynamics of supercooled colloidal and molecular fluids approaching a glass
transition.

text: The conserved role of Notch signaling in controlling intestinal cell fate
specification and homeostasis has been extensively studied. Nevertheless, the
precise identity of the cells in which Notch signaling is active and the role
of different Notch receptor paralogues in the intestine remain ambiguous, due
to the lack of reliable tools to investigate Notch expression and function in
vivo. We generated a new series of transgenic mice that allowed us, by lineage
analysis, to formally prove that Notch1 and Notch2 are specifically expressed
in crypt stem cells. In addition, a novel Notch reporter mouse, Hes1-EmGFP SAT,
demonstrated exclusive Notch activity in crypt stem cells and absorptive progenitors.
This roster of knock-in and reporter mice represents a valuable resource to functionally
explore the Notch pathway in vivo in virtually all tissues.

text: Iron is a ubiquitous impurity in metamict (radiation-damaged and partially
amorphized) materials such as titanite (CaSiTiO5). Using 57Fe Mössbauer spectroscopy
we find that iron in metamict titanite is partitioned between amorphous and crystalline
regions based on valence. Trivalent iron exists in the crystalline titanite matrix
whereas divalent iron exists almost exclusively in radiation-amorphized regions.
We find that the relative abundances of the oxidation states correlate with the
volume fraction of amorphous and crystalline regions. Our data also show that
oxidation of iron proceeds along with the recrystallization of the amorphized
regions. Recrystallization is confirmed to occur over the range 700 °C < T < 925 °C,
and no further structural changes are observed at higher temperatures. It is surprising
that our Mössbauer measurements show divalent iron to be surrounded by titanite
with a high degree of short-range structural order in the amorphized regions.
This observation is fundamentally different from other metamict materials such
as zircon (ZrSiO4), where amorphized regions show no short-range order.

text: Pb, Te, Ag and Se, when reacted in a 1:1:x:1 (x = 1.9, 2.0, 2.01) molar ratio,
form a two phase composite which consists of a phase which crystallizes in the
fcc cubic PbSe structure and a phase that crystallizes in the Ag2Te structure.
In this article, we demonstrate that by varying the Ag concentration, we can manipulate
which variant of the Ag2Te structure stabilizes at room temperature (monoclinic
α-Ag2Te or cubic β-Ag1.9Te) and can consequently manipulate the electrical and
thermal transport behavior of the composite and hence the thermoelectric performance.
Additionally, we show that Cu-doping results in an overall improvement in thermoelectric
performance. Our results suggest that formation of composites is a viable path
for achieving a phonon-glass-electron-crystal (PGEC) alloy.

text: 'Li-ion batteries have transformed portable electronics and will play a key
role in the electrification of transport. However, the highest energy storage
possible for Li-ion batteries is insufficient for the long-term needs of society,
for example, extended-range electric vehicles. To go beyond the horizon of Li-ion
batteries is a formidable challenge; there are few options. Here we consider two:
Li–air (O2) and Li–S. The energy that can be stored in Li–air (based on aqueous
or non-aqueous electrolytes) and Li–S cells is compared with Li-ion; the operation
of the cells is discussed, as are the significant hurdles that will have to be
overcome if such batteries are to succeed. Fundamental scientific advances in
understanding the reactions occurring in the cells as well as new materials are
key to overcoming these obstacles. The potential benefits of Li–air and Li–S justify
the continued research effort that will be needed.'

of the non‐aqueous Li–O2 battery. Although ether‐based electrolytes do from Li2O2

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.

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.
