text: The rate of biological evolution depends on the fixation probability and on
the fixation time of new mutants. Intensive research has focused on identifying
population structures that augment the fixation probability of advantageous mutants.
But these amplifiers of natural selection typically increase fixation time. Here
we study population structures that achieve a tradeoff between fixation probability
and time. First, we show that no amplifiers can have an asymptotically lower absorption
time than the well-mixed population. Then we design population structures that
substantially augment the fixation probability with just a minor increase in fixation
time. Finally, we show that those structures enable higher effective rate of evolution
than the well-mixed population provided that the rate of generating advantageous
mutants is relatively low. Our work sheds light on how population structure affects
the rate of evolution. Moreover, our structures could be useful for lab-based,
medical, or industrial applications of evolutionary optimization.

text: "Background: Many cancer genomes are extensively rearranged with highly aberrant
chromosomal karyotypes. Structural and copy number variations in cancer genomes
can be determined via abnormal mapping of sequenced reads to the reference genome.
Recently it became possible to reconcile both of these types of large-scale variations
into a karyotype graph representation of the rearranged cancer genomes. Such a
representation, however, does not directly describe the linear and/or circular
structure of the underlying rearranged cancer chromosomes, thus limiting possible
analysis of cancer genomes somatic evolutionary process as well as functional
genomic changes brought by the large-scale genome rearrangements.\r\n\r\nResults:
Here we address the aforementioned limitation by introducing a novel methodological
framework for recovering rearranged cancer chromosomes from karyotype graphs.
For a cancer karyotype graph we formulate an Eulerian Decomposition Problem (EDP)
of finding a collection of linear and/or circular rearranged cancer chromosomes
that are determined by the graph. We derive and prove computational complexities
for several variations of the EDP. We then demonstrate that Eulerian decomposition
of the cancer karyotype graphs is not always unique and present the Consistent
Contig Covering Problem (CCCP) of recovering unambiguous cancer contigs from the
cancer karyotype graph, and describe a novel algorithm CCR capable of solving
CCCP in polynomial time. We apply CCR on a prostate cancer dataset and demonstrate
that it is capable of consistently recovering large cancer contigs even when underlying
cancer genomes are highly rearranged.\r\n\r\nConclusions: CCR can recover rearranged
cancer contigs from karyotype graphs thereby addressing existing limitation in
inferring chromosomal structures of rearranged cancer genomes and advancing our
understanding of both patient/cancer-specific as well as the overall genetic instability
in cancer."

text: 'We present LiveTraVeL (Live Transit Vehicle Labeling), a real-time system
to label a stream of noisy observations of transit vehicle trajectories with the
transit routes they are serving (e.g., northbound bus #5). In order to scale efficiently
to large transit networks, our system first retrieves a small set of candidate
routes from a geometrically indexed data structure, then applies a fine-grained
scoring step to choose the best match. Given that real-time data remains unavailable
for the majority of the world’s transit agencies, these inferences can help feed
a real-time map of a transit system’s trips, infer transit trip delays in real
time, or measure and correct noisy transit tracking data. This system can run
on vehicle observations from a variety of sources that don’t attach route information
to vehicle observations, such as public imagery streams or user-contributed transit
vehicle sightings.We abstract away the specifics of the sensing system and demonstrate
the effectiveness of our system on a "semisynthetic" dataset of all New York City
buses, where we simulate sensed trajectories by starting with fully labeled vehicle
trajectories reported via the GTFS-Realtime protocol, removing the transit route
IDs, and perturbing locations with synthetic noise. Using just the geometric shapes
of the trajectories, we demonstrate that our system converges on the correct route
ID within a few minutes, even after a vehicle switches from serving one trip to
the next.'

text: "This is a literature teaching resource review for biologically inspired microfluidics
courses\r\nor exploring the diverse applications of microfluidics. The structure
is around key papers and model\r\norganisms. While courses gradually change over
time, a focus remains on understanding how\r\nmicrofluidics has developed as well
as what it can and cannot do for researchers. As a primary\r\nstarting point,
we cover micro-fluid mechanics principles and microfabrication of devices. A variety\r\nof
applications are discussed using model prokaryotic and eukaryotic organisms from
the set\r\nof bacteria (Escherichia coli), trypanosomes (Trypanosoma brucei),
yeast (Saccharomyces cerevisiae),\r\nslime molds (Physarum polycephalum), worms
(Caenorhabditis elegans), flies (Drosophila melangoster),\r\nplants (Arabidopsis

methods discussed include biomimetics, organ on a chip, inkjet, droplet microfluidics,\r\nbiotic
games, and diagnostics. While we have not yet reached the end-all lab on a chip,\r\nmicrofluidics
can still be used effectively for specific applications."

significant traction among modern programming languages. The common abstraction
for communication between several processes is the channel. Although channels
are similar to producer-consumer data structures, they have different semantics
and support additional operations, such as the select expression. Despite their
growing popularity, most known implementations of channels use lock-based data
structures and can be rather inefficient.\r\n\r\nIn this paper, we present the
first efficient lock-free algorithm for implementing a communication channel for
CSP programming. We provide implementations and experimental results in the Kotlin
and Go programming languages. Our new algorithm outperforms existing implementations
on many workloads, while providing non-blocking progress guarantee. Our design
can serve as an example of how to construct general communication data structures
for CSP and actor models. "

text: Simple drawings of graphs are those in which each pair of edges share at most
one point, either a common endpoint or a proper crossing. In this paper we study
the problem of extending a simple drawing D(G) of a graph G by inserting a set
of edges from the complement of G into D(G) such that the result is a simple drawing.
In the context of rectilinear drawings, the problem is trivial. For pseudolinear
drawings, the existence of such an extension follows from Levi’s enlargement lemma.
In contrast, we prove that deciding if a given set of edges can be inserted into
a simple drawing is NP-complete. Moreover, we show that the maximization version
of the problem is APX-hard. We also present a polynomial-time algorithm for deciding
whether one edge uv can be inserted into D(G) when {u,v} is a dominating set for
the graph G.

text: Piecewise Barrier Tubes (PBT) is a new technique for flowpipe overapproximation
for nonlinear systems with polynomial dynamics, which leverages a combination
of barrier certificates. PBT has advantages over traditional time-step based methods
in dealing with those nonlinear dynamical systems in which there is a large difference
in speed between trajectories, producing an overapproximation that is time independent.
However, the existing approach for PBT is not efficient due to the application
of interval methods for enclosure-box computation, and it can only deal with continuous
dynamical systems without uncertainty. In this paper, we extend the approach with
the ability to handle both continuous and hybrid dynamical systems with uncertainty
that can reside in parameters and/or noise. We also improve the efficiency of
the method significantly, by avoiding the use of interval-based methods for the
enclosure-box computation without loosing soundness. We have developed a C++ prototype
implementing the proposed approach and we evaluate it on several benchmarks. The
experiments show that our approach is more efficient and precise than other methods
in the literature.

text: 'We present Mixed-time Signal Temporal Logic (STL−MX), a specification formalism
which extends STL by capturing the discrete/ continuous time duality found in
many cyber-physical systems (CPS), as well as mixed-signal electronic designs.
In STL−MX, properties of components with continuous dynamics are expressed in
STL, while specifications of components with discrete dynamics are written in
LTL. To combine the two layers, we evaluate formulas on two traces, discrete-
and continuous-time, and introduce two interface operators that map signals, properties
and their satisfaction signals across the two time domains. We show that STL-mx
has the expressive power of STL supplemented with an implicit T-periodic clock
signal. We develop and implement an algorithm for monitoring STL-mx formulas and
illustrate the approach using a mixed-signal example. '

text: Aprotic alkali metal–oxygen batteries require reversible formation of metal
superoxide or peroxide on cycling. Severe parasitic reactions cause poor rechargeability,
efficiency, and cycle life and have been shown to be caused by singlet oxygen
(1O2) that forms at all stages of cycling. However, its formation mechanism remains
unclear. We show that disproportionation of superoxide, the product or intermediate
on discharge and charge, to peroxide and oxygen is responsible for 1O2 formation.
While the overall reaction is driven by the stability of peroxide and thus favored
by stronger Lewis acidic cations such as Li+, the 1O2 fraction is enhanced by
weak Lewis acids such as organic cations. Concurrently, the metal peroxide yield
drops with increasing 1O2. The results explain a major parasitic pathway during
cell cycling and the growing severity in K–, Na–, and Li–O2 cells based on the
growing propensity for disproportionation. High capacities and rates with peroxides
are now realized to require solution processes, which form peroxide or release
O2via disproportionation. The results therefore establish the central dilemma
that disproportionation is required for high capacity but also responsible for
irreversible reactions. Highly reversible cell operation requires hence finding
reaction routes that avoid disproportionation.

text: Singlet oxygen (1O2) causes a major fraction of the parasitic chemistry during
the cycling of non‐aqueous alkali metal‐O2 batteries and also contributes to interfacial
reactivity of transition‐metal oxide intercalation compounds. We introduce DABCOnium,
the mono alkylated form of 1,4‐diazabicyclo[2.2.2]octane (DABCO), as an efficient
1O2 quencher with an unusually high oxidative stability of ca. 4.2 V vs. Li/Li+.
Previous quenchers are strongly Lewis basic amines with too low oxidative stability.
DABCOnium is an ionic liquid, non‐volatile, highly soluble in the electrolyte,
stable against superoxide and peroxide, and compatible with lithium metal. The
electrochemical stability covers the required range for metal–O2 batteries and
greatly reduces 1O2 related parasitic chemistry as demonstrated for the Li–O2
cell.

text: Non-aqueous lithium-oxygen batteries cycle by forming lithium peroxide during
discharge and oxidizing it during recharge. The significant problem of oxidizing
the solid insulating lithium peroxide can greatly be facilitated by incorporating
redox mediators that shuttle electron-holes between the porous substrate and lithium
peroxide. Redox mediator stability is thus key for energy efficiency, reversibility,
and cycle life. However, the gradual deactivation of redox mediators during repeated
cycling has not conclusively been explained. Here, we show that organic redox
mediators are predominantly decomposed by singlet oxygen that forms during cycling.
Their reaction with superoxide, previously assumed to mainly trigger their degradation,
peroxide, and dioxygen, is orders of magnitude slower in comparison. The reduced
form of the mediator is markedly more reactive towards singlet oxygen than the
oxidized form, from which we derive reaction mechanisms supported by density functional
theory calculations. Redox mediators must thus be designed for stability against
singlet oxygen.

text: Li–O2 batteries are plagued by side reactions that cause poor rechargeability
and efficiency. These reactions were recently revealed to be predominantly caused
by singlet oxygen, which can be neutralized by chemical traps or physical quenchers.
However, traps are irreversibly consumed and thus only active for a limited time,
and so far identified quenchers lack oxidative stability to be suitable for typically
required recharge potentials. Thus, reducing the charge potential within the stability
limit of the quencher and/or finding more stable quenchers is required. Here,
we show that dimethylphenazine as a redox mediator decreases the charge potential
well within the stability limit of the quencher 1,4-diazabicyclo[2.2.2]octane.
The quencher can thus mitigate the parasitic reactions without being oxidatively
decomposed. At the same time the quencher protects the redox mediator from singlet
oxygen attack. The mutual conservation of the redox mediator and the quencher
is rational for stable and effective Li–O2 batteries.

text: In this issue of Joule, Dongmin Im and coworkers from Samsung in South Korea
describe a prototype lithium-O2 battery that reaches ∼700 Wh kg–1 and ∼600 Wh
L–1 on the cell level. They cut all components to the minimum to reach this value.
Difficulties filling the pores with discharge product and inhomogeneous cell utilization
turn out to limit the achievable energy. Their work underlines the importance
of reporting performance with respect to full cell weight and volume.

text: We consider the space of probability measures on a discrete set X, endowed
with a dynamical optimal transport metric. Given two probability measures supported
in a subset Y⊆X, it is natural to ask whether they can be connected by a constant
speed geodesic with support in Y at all times. Our main result answers this question
affirmatively, under a suitable geometric condition on Y introduced in this paper.
The proof relies on an extension result for subsolutions to discrete Hamilton-Jacobi
equations, which is of independent interest.

text: Coupling of endoplasmic reticulum stress to dimerisation‑dependent activation
of the UPR transducer IRE1 is incompletely understood. Whilst the luminal co-chaperone
ERdj4 promotes a complex between the Hsp70 BiP and IRE1's stress-sensing luminal
domain (IRE1LD) that favours the latter's monomeric inactive state and loss of
ERdj4 de-represses IRE1, evidence linking these cellular and in vitro observations
is presently lacking. We report that enforced loading of endogenous BiP onto endogenous
IRE1α repressed UPR signalling in CHO cells and deletions in the IRE1α locus that
de-repressed the UPR in cells, encode flexible regions of IRE1LD that mediated
BiP‑induced monomerisation in vitro. Changes in the hydrogen exchange mass spectrometry
profile of IRE1LD induced by ERdj4 and BiP confirmed monomerisation and were consistent
with active destabilisation of the IRE1LD dimer. Together, these observations
support a competition model whereby waning ER stress passively partitions ERdj4
and BiP to IRE1LD to initiate active repression of UPR signalling.

text: Telencephalic organoids generated from human pluripotent stem cells (hPSCs)
are emerging as an effective system to study the distinct features of the developing
human brain and the underlying causes of many neurological disorders. While progress
in organoid technology has been steadily advancing, many challenges remain including
rampant batch-to-batch and cell line-to-cell line variability and irreproducibility.
Here, we demonstrate that a major contributor to successful cortical organoid
production is the manner in which hPSCs are maintained prior to differentiation.
Optimal results were achieved using fibroblast-feeder-supported hPSCs compared
to feeder-independent cells, related to differences in their transcriptomic states.
Feeder-supported hPSCs display elevated activation of diverse TGFβ superfamily
signaling pathways and increased expression of genes associated with naïve pluripotency.
We further identify combinations of TGFβ-related growth factors that are necessary
and together sufficient to impart broad telencephalic organoid competency to feeder-free
hPSCs and enable reproducible formation of brain structures suitable for disease
modeling.
