text: Neuropeptides are ubiquitous modulators of behavior and physiology. They are
packaged in specialized secretory organelles called dense core vesicles (DCVs)
that are released upon neural stimulation. Unlike synaptic vesicles, which can
be recycled and refilled close to release sites, DCVs must be replenished by de
novo synthesis in the cell body. Here, we dissect DCV cell biology in vivo in
a Caenorhabditis elegans sensory neuron whose tonic activity we can control using
a natural stimulus. We express fluorescently tagged neuropeptides in the neuron
and define parameters that describe their subcellular distribution. We measure
these parameters at high and low neural activity in 187 mutants defective in proteins
implicated in membrane traffic, neuroendocrine secretion, and neuronal or synaptic
activity. Using unsupervised hierarchical clustering methods, we analyze these
data and identify 62 groups of genes with similar mutant phenotypes. We explore
the function of a subset of these groups. We recapitulate many previous findings,
validating our paradigm. We uncover a large battery of proteins involved in recycling
DCV membrane proteins, something hitherto poorly explored. We show that the unfolded
protein response promotes DCV production, which may contribute to intertissue
communication of stress. We also find evidence that different mechanisms of priming
and exocytosis may operate at high and low neural activity. Our work provides
a defined framework to study DCV biology at different neural activity levels.

text: In this paper, we propose an algorithm to build discrete spherical shell having
integer center and real-valued inner and outer radii on the face-centered cubic
(FCC) grid. We address the problem by mapping it to a 2D scenario and building
the shell layer by layer on hexagonal grids with additive manufacturing in mind.
The layered hexagonal grids get shifted according to need as we move from one
layer to another and forms the FCC grid in 3D. However, we restrict our computation
strictly to 2D in order to utilize symmetry and simplicity.

text: Blood platelets are critical for hemostasis and thrombosis, but also play
diverse roles during immune responses. We have recently reported that platelets
migrate at sites of infection in vitro and in vivo. Importantly, platelets use
their ability to migrate to collect and bundle fibrin (ogen)-bound bacteria accomplishing
efficient intravascular bacterial trapping. Here, we describe a method that allows
analyzing platelet migration in vitro, focusing on their ability to collect bacteria
and trap bacteria under flow.

text: An optical network of superconducting quantum bits (qubits) is an appealing
platform for quantum communication and distributed quantum computing, but developing
a quantum-compatible link between the microwave and optical domains remains an
outstanding challenge. Operating at T < 100 mK temperatures, as required for quantum
electrical circuits, we demonstrate a mechanically mediated microwave–optical
converter with 47% conversion efficiency, and use a classical feed-forward protocol
to reduce added noise to 38 photons. The feed-forward protocol harnesses our discovery
that noise emitted from the two converter output ports is strongly correlated
because both outputs record thermal motion of the same mechanical mode. We also
discuss a quantum feed-forward protocol that, given high system efficiencies,
would allow quantum information to be transferred even when thermal phonons enter
the mechanical element faster than the electro-optic conversion rate.

text: We construct a metamaterial from radio-frequency harmonic oscillators, and
find two topologically distinct phases resulting from dissipation engineered into
the system. These phases are distinguished by a quantized value of bulk energy
transport. The impulse response of our circuit is measured and used to reconstruct
the band structure and winding number of circuit eigenfunctions around a dark
mode. Our results demonstrate that dissipative topological transport can occur
in a wider class of physical systems than considered before.

text: This chapter finds an agreement of equivariant indices of semi-classical homomorphisms
between pairwise mirror branes in the GL2 Higgs moduli space on a Riemann surface.
On one side of the agreement, components of the Lagrangian brane of U(1,1) Higgs
bundles, whose mirror was proposed by Hitchin to be certain even exterior powers
of the hyperholomorphic Dirac bundle on the SL2 Higgs moduli space, are present.
The agreement arises from a mysterious functional equation. This gives strong
computational evidence for Hitchin’s proposal.

text: Reed-Muller (RM) and polar codes are a class of capacity-achieving channel
coding schemes with the same factor graph representation. Low-complexity decoding
algorithms fall short in providing a good error-correction performance for RM
and polar codes. Using the symmetric group of RM and polar codes, the specific
decoding algorithm can be carried out on multiple permutations of the factor graph
to boost the error-correction performance. However, this approach results in high
decoding complexity. In this paper, we first derive the total number of factor
graph permutations on which the decoding can be performed. We further propose
a successive permutation (SP) scheme which finds the permutations on the fly,
thus the decoding always progresses on a single factor graph permutation. We show
that SP can be used to improve the error-correction performance of RM and polar
codes under successive-cancellation (SC) and SC list (SCL) decoding, while keeping
the memory requirements of the decoders unaltered. Our results for RM and polar
codes of length 128 and rate 0.5 show that when SP is used and at a target frame
error rate of 10 -4 , up to 0.5 dB and 0.1 dB improvement can be achieved for
RM and polar codes respectively.

text: Polar codes represent one of the major recent breakthroughs in coding theory
and, because of their attractive features, they have been selected for the incoming
5G standard. As such, a lot of attention has been devoted to the development of
decoding algorithms with good error performance and efficient hardware implementation.
One of the leading candidates in this regard is represented by successive-cancellation
list (SCL) decoding. However, its hardware implementation requires a large amount
of memory. Recently, a partitioned SCL (PSCL) decoder has been proposed to significantly
reduce the memory consumption. In this paper, we consider the paradigm of PSCL
decoding from a practical standpoint, and we provide several improvements. First,
by changing the target signal-to-noise ratio and consequently modifying the construction
of the code, we are able to improve the performance at no additional computational,
latency, or memory cost. Second, we bridge the performance gap between SCL and
PSCL decoding by introducing a generalized PSCL decoder and a layered PSCL decoder.
In this way, we obtain almost the same performance of the SCL decoder with a significantly
lower memory requirement, as testified by hardware implementation results. Third,
we present an optimal scheme to allocate cyclic redundancy checks. Finally, we
provide a lower bound on the list size that guarantees optimal maximum a posteriori
performance for the binary erasure channel.

text: Polar codes are a channel coding scheme for the next generation of wireless
communications standard (5G). The belief propagation (BP) decoder allows for parallel
decoding of polar codes, making it suitable for high throughput applications.
However, the error-correction performance of polar codes under BP decoding is
far from the requirements of 5G. It has been shown that the error-correction performance
of BP can be improved if the decoding is performed on multiple permuted factor
graphs of polar codes. However, a different BP decoding scheduling is required
for each factor graph permutation which results in the design of a different decoder
for each permutation. Moreover, the selection of the different factor graph permutations
is at random, which prevents the decoder to achieve a desirable error correction
performance with a small number of permutations. In this paper, we first show
that the permutations on the factor graph can be mapped into suitable permutations
on the codeword positions. As a result, we can make use of a single decoder for
all the permutations. In addition, we introduce a method to construct a set of
predetermined permutations which can provide the correct codeword if the decoding
fails on the original permutation. We show that for the 5G polar code of length
1024, the error-correction performance of the proposed decoder is more than 0.25
dB better than that of the BP decoder with the same number of random permutations
at the frame error rate of 10 -4 .
