text: Optimal decision making requires individuals to know their available options
and to anticipate correctly what consequences these options have. In many social
interactions, however, we refrain from gathering all relevant information, even
if this information would help us make better decisions and is costless to obtain.
This chapter examines several examples of “deliberate ignorance.” Two simple models
are proposed to illustrate how ignorance can evolve among self-interested and
payoff - maximizing individuals, and open problems are highlighted that lie ahead
for future research to explore.

text: We present a computational design system that assists users to model, optimize,
and fabricate quad-robots with soft skins. Our system addresses the challenging
task of predicting their physical behavior by fully integrating the multibody
dynamics of the mechanical skeleton and the elastic behavior of the soft skin.
The developed motion control strategy uses an alternating optimization scheme
to avoid expensive full space time-optimization, interleaving space-time optimization
for the skeleton, and frame-by-frame optimization for the full dynamics. The output
are motor torques to drive the robot to achieve a user prescribed motion trajectory.
We also provide a collection of convenient engineering tools and empirical manufacturing
guidance to support the fabrication of the designed quad-robot. We validate the
feasibility of designs generated with our system through physics simulations and
with a physically-fabricated prototype.

text: The dynamics of a triangular magnetocapillary swimmer is studied using the
lattice Boltzmann method. We extend on our previous work, which deals with the
self-assembly and a specific type of the swimmer motion characterized by the swimmer’s
maximum velocity centred around the particle’s inverse viscous time. Here, we
identify additional regimes of motion. First, modifying the ratio of surface tension
and magnetic forces allows to study the swimmer propagation in the regime of significantly
lower frequencies mainly defined by the strength of the magnetocapillary potential.
Second, introducing a constant magnetic contribution in each of the particles
in addition to their magnetic moment induced by external fields leads to another
regime characterized by strong in-plane swimmer reorientations that resemble experimental
observations.

text: Microtubule plus-end depolymerization rate is a potentially important target
of physiological regulation, but it has been challenging to measure, so its role
in spatial organization is poorly understood. Here we apply a method for tracking
plus ends based on time difference imaging to measure depolymerization rates in
large interphase asters growing in Xenopus egg extract. We observed strong spatial
regulation of depolymerization rates, which were higher in the aster interior
compared with the periphery, and much less regulation of polymerization or catastrophe
rates. We interpret these data in terms of a limiting component model, where aster
growth results in lower levels of soluble tubulin and microtubule-associated proteins
(MAPs) in the interior cytosol compared with that at the periphery. The steady-state
polymer fraction of tubulin was ∼30%, so tubulin is not strongly depleted in the
aster interior. We propose that the limiting component for microtubule assembly
is a MAP that inhibits depolymerization, and that egg asters are tuned to low
microtubule density.

text: Inositol hexakisphosphate (IP6) is an assembly cofactor for HIV-1. We report
here that IP6 is also used for assembly of Rous sarcoma virus (RSV), a retrovirus
from a different genus. IP6 is ~100-fold more potent at promoting RSV mature capsid
protein (CA) assembly than observed for HIV-1 and removal of IP6 in cells reduces
infectivity by 100-fold. Here, visualized by cryo-electron tomography and subtomogram
averaging, mature capsid-like particles show an IP6-like density in the CA hexamer,
coordinated by rings of six lysines and six arginines. Phosphate and IP6 have
opposing effects on CA in vitro assembly, inducing formation of T = 1 icosahedrons
and tubes, respectively, implying that phosphate promotes pentamer and IP6 hexamer
formation. Subtomogram averaging and classification optimized for analysis of
pleomorphic retrovirus particles reveal that the heterogeneity of mature RSV CA
polyhedrons results from an unexpected, intrinsic CA hexamer flexibility. In contrast,
the CA pentamer forms rigid units organizing the local architecture. These different
features of hexamers and pentamers determine the structural mechanism to form
CA polyhedrons of variable shape in mature RSV particles.

text: The ability to adapt to changes in stimulus statistics is a hallmark of sensory
systems. Here, we developed a theoretical framework that can account for the dynamics
of adaptation from an information processing perspective. We use this framework
to optimize and analyze adaptive sensory codes, and we show that codes optimized
for stationary environments can suffer from prolonged periods of poor performance
when the environment changes. To mitigate the adversarial effects of these environmental
changes, sensory systems must navigate tradeoffs between the ability to accurately
encode incoming stimuli and the ability to rapidly detect and adapt to changes
in the distribution of these stimuli. We derive families of codes that balance
these objectives, and we demonstrate their close match to experimentally observed
neural dynamics during mean and variance adaptation. Our results provide a unifying
perspective on adaptation across a range of sensory systems, environments, and
sensory tasks.

text: "Isomanifolds are the generalization of isosurfaces to arbitrary dimension
and codimension, i.e. submanifolds of ℝ^d defined as the zero set of some multivariate
multivalued smooth function f: ℝ^d → ℝ^{d-n}, where n is the intrinsic dimension
of the manifold. A natural way to approximate a smooth isomanifold M is to consider
its Piecewise-Linear (PL) approximation M̂ based on a triangulation \U0001D4AF
of the ambient space ℝ^d. In this paper, we describe a simple algorithm to trace
isomanifolds from a given starting point. The algorithm works for arbitrary dimensions
n and d, and any precision D. Our main result is that, when f (or M) has bounded
complexity, the complexity of the algorithm is polynomial in d and δ = 1/D (and
unavoidably exponential in n). Since it is known that for δ = Ω (d^{2.5}), M̂
is O(D²)-close and isotopic to M, our algorithm produces a faithful PL-approximation
of isomanifolds of bounded complexity in time polynomial in d. Combining this
algorithm with dimensionality reduction techniques, the dependency on d in the
size of M̂ can be completely removed with high probability. We also show that
the algorithm can handle isomanifolds with boundary and, more generally, isostratifolds.
The algorithm for isomanifolds with boundary has been implemented and experimental
results are reported, showing that it is practical and can handle cases that are
far ahead of the state-of-the-art. "

text: Endoplasmic reticulum–plasma membrane contact sites (ER–PM CS) play fundamental
roles in all eukaryotic cells. Arabidopsis thaliana mutants lacking the ER–PM
protein tether synaptotagmin1 (SYT1) exhibit decreased PM integrity under multiple
abiotic stresses, such as freezing, high salt, osmotic stress, and mechanical
damage. Here, we show that, together with SYT1, the stress-induced SYT3 is an
ER–PM tether that also functions in maintaining PM integrity. The ER–PM CS localization
of SYT1 and SYT3 is dependent on PM phosphatidylinositol-4-phosphate and is regulated
by abiotic stress. Lipidomic analysis revealed that cold stress increased the
accumulation of diacylglycerol at the PM in a syt1/3 double mutant relative to
wild-type while the levels of most glycerolipid species remain unchanged. In addition,
the SYT1-green fluorescent protein fusion preferentially binds diacylglycerol
in vivo with little affinity for polar glycerolipids. Our work uncovers a SYT-dependent
mechanism of stress adaptation counteracting the detrimental accumulation of diacylglycerol
at the PM produced during episodes of abiotic stress.

text: 'Lithium bis(trifluoromethylsulfonyl)imide (LiTFSI) based water-in-salt electrolytes
(WiSEs) has recently emerged as a new promising class of electrolytes, primarily
owing to their wide electrochemical stability windows (~3–4 V), that by far exceed
the thermodynamic stability window of water (1.23 V). Upon increasing the salt
concentration towards superconcentration the onset of the oxygen evolution reaction
(OER) shifts more significantly than the hydrogen evolution reaction (HER) does.
The OER shift has been explained by the accumulation of hydrophobic anions blocking
water access to the electrode surface, hence by double layer theory. Here we demonstrate
that the processes during oxidation are much more complex, involving OER, carbon
and salt decomposition by OER intermediates, and salt precipitation upon local
oversaturation. The positive shift in the onset potential of oxidation currents
was elucidated by combining several advanced analysis techniques: rotating ring-disk
electrode voltammetry, online electrochemical mass spectrometry, and X-ray photoelectron
spectroscopy, using both dilute and superconcentrated electrolytes. The results
demonstrate the importance of reactive OER intermediates and surface films for
electrolyte and electrode stability and motivate further studies of the nature
of the electrode.'

text: We consider a system of N trapped bosons with repulsive interactions in a
combined semiclassical mean-field limit at positive temperature. We show that
the free energy is well approximated by the minimum of the Hartree free energy
functional – a natural extension of the Hartree energy functional to positive
temperatures. The Hartree free energy functional converges in the same limit to
a semiclassical free energy functional, and we show that the system displays Bose–Einstein
condensation if and only if it occurs in the semiclassical free energy functional.
This allows us to show that for weak coupling the critical temperature decreases
due to the repulsive interactions.

text: "Given a locally finite set \U0001D44B⊆ℝ\U0001D451 and an integer \U0001D458≥0,
we consider the function \U0001D430\U0001D458:Del\U0001D458(\U0001D44B)→ℝ on the
dual of the order-k Voronoi tessellation, whose sublevel sets generalize the notion
of alpha shapes from order-1 to order-k (Edelsbrunner et al. in IEEE Trans Inf
Theory IT-29:551–559, 1983; Krasnoshchekov and Polishchuk in Inf Process Lett
114:76–83, 2014). While this function is not necessarily generalized discrete
Morse, in the sense of Forman (Adv Math 134:90–145, 1998) and Freij (Discrete
Math 309:3821–3829, 2009), we prove that it satisfies similar properties so that
its increments can be meaningfully classified into critical and non-critical steps.
This result extends to the case of weighted points and sheds light on k-fold covers
with balls in Euclidean space."

text: "Turbulence in the flow of fluid through a pipe can be suppressed by buoyancy
forces. As the suppression of turbulence leads to severe heat transfer deterioration,
this is an important and undesirable phenomenon in both heating and cooling applications.
Vertical flow is often considered, as the axial buoyancy force can help drive
the flow. With heating measured by the buoyancy parameter \U0001D436, our direct
numerical simulations show that shear-driven turbulence may either be completely
laminarised or it transitions to a relatively quiescent convection-driven state.
Buoyancy forces cause a flattening of the base flow profile, which in isothermal
pipe flow has recently been linked to complete suppression of turbulence (Kühnen
et al., Nat. Phys., vol. 14, 2018, pp. 386–390), and the flattened laminar base
profile has enhanced nonlinear stability (Marensi et al., J. Fluid Mech., vol.
863, 2019, pp. 50–875). In agreement with these findings, the nonlinear lower-branch
travelling-wave solution analysed here, which is believed to mediate transition
to turbulence in isothermal pipe flow, is shown to be suppressed by buoyancy.
A linear instability of the laminar base flow is responsible for the appearance
of the relatively quiescent convection driven state for \U0001D436≳4 across the
range of Reynolds numbers considered. In the suppression of turbulence, however,
i.e. in the transition from turbulence, we find clearer association with the analysis
of He et al. (J. Fluid Mech., vol. 809, 2016, pp. 31–71) than with the above dynamical
systems approach, which describes better the transition to turbulence. The laminarisation
criterion He et al. propose, based on an apparent Reynolds number of the flow
as measured by its driving pressure gradient, is found to capture the critical
\U0001D436=\U0001D436\U0001D450\U0001D45F(\U0001D445\U0001D452) above which the
flow will be laminarised or switch to the convection-driven type. Our analysis
suggests that it is the weakened rolls, rather than the streaks, which appear
to be critical for laminarisation."

text: "Motivated by the successful application of geometry to proving the Harary--Hill
conjecture for “pseudolinear” drawings of $K_n$, we introduce “pseudospherical”
drawings of graphs. A spherical drawing of a graph $G$ is a drawing in the unit
sphere $\\mathbb{S}^2$ in which the vertices of $G$ are represented as points---no
three on a great circle---and the edges of $G$ are shortest-arcs in $\\mathbb{S}^2$
connecting pairs of vertices. Such a drawing has three properties: (1) every edge
$e$ is contained in a simple closed curve $\\gamma_e$ such that the only vertices
in $\\gamma_e$ are the ends of $e$; (2) if $e\\ne f$, then $\\gamma_e\\cap\\gamma_f$
has precisely two crossings; and (3) if $e\\ne f$, then $e$ intersects $\\gamma_f$
at most once, in either a crossing or an end of $e$. We use properties (1)--(3)
to define a pseudospherical drawing of $G$. Our main result is that for the complete
graph, properties (1)--(3) are equivalent to the same three properties but with
“precisely two crossings” in (2) replaced by “at most two crossings.” The proof
requires a result in the geometric transversal theory of arrangements of pseudocircles.
This is proved using the surprising result that the absence of special arcs (coherent
spirals) in an arrangement of simple closed curves characterizes the fact that
any two curves in the arrangement have at most two crossings. Our studies provide
the necessary ideas for exhibiting a drawing of $K_{10}$ that has no extension
to an arrangement of pseudocircles and a drawing of $K_9$ that does extend to
an arrangement of pseudocircles, but no such extension has all pairs of pseudocircles
crossing twice.\r\n"

text: The hexameric AAA-ATPase Drg1 is a key factor in eukaryotic ribosome biogenesis
and initiates cytoplasmic maturation of the large ribosomal subunit by releasing
the shuttling maturation factor Rlp24. Drg1 monomers contain two AAA-domains (D1
and D2) that act in a concerted manner. Rlp24 release is inhibited by the drug
diazaborine which blocks ATP hydrolysis in D2. The mode of inhibition was unknown.
Here we show the first cryo-EM structure of Drg1 revealing the inhibitory mechanism.
Diazaborine forms a covalent bond to the 2′-OH of the nucleotide in D2, explaining
its specificity for this site. As a consequence, the D2 domain is locked in a
rigid, inactive state, stalling the whole Drg1 hexamer. Resistance mechanisms
identified include abolished drug binding and altered positioning of the nucleotide.
Our results suggest nucleotide-modifying compounds as potential novel inhibitors
for AAA-ATPases.

text: The Massively Parallel Computation (MPC) model is an emerging model that distills
core aspects of distributed and parallel computation, developed as a tool to solve
combinatorial (typically graph) problems in systems of many machines with limited
space. Recent work has focused on the regime in which machines have sublinear
(in n, the number of nodes in the input graph) space, with randomized algorithms
presented for the fundamental problems of Maximal Matching and Maximal Independent
Set. However, there have been no prior corresponding deterministic algorithms.
A major challenge underlying the sublinear space setting is that the local space
of each machine might be too small to store all edges incident to a single node.
This poses a considerable obstacle compared to classical models in which each
node is assumed to know and have easy access to its incident edges. To overcome
this barrier, we introduce a new graph sparsification technique that deterministically
computes a low-degree subgraph, with the additional property that solving the
problem on this subgraph provides significant progress towards solving the problem
for the original input graph. Using this framework to derandomize the well-known
algorithm of Luby [SICOMP’86], we obtain O(log Δ + log log n)-round deterministic
MPC algorithms for solving the problems of Maximal Matching and Maximal Independent
Set with O(nɛ) space on each machine for any constant ɛ > 0. These algorithms
also run in O(log Δ) rounds in the closely related model of CONGESTED CLIQUE,
improving upon the state-of-the-art bound of O(log 2Δ) rounds by Censor-Hillel
et al. [DISC’17].

text: We consider the problem ofdistributed mean estimation (DME), in which n machines
are each given a local d-dimensional vector xv∈Rd, and must cooperate to estimate
the mean of their inputs μ=1n∑nv=1xv, while minimizing total communication cost.
DME is a fundamental construct in distributed machine learning, and there has
been considerable work on variants of this problem, especially in the context
of distributed variance reduction for stochastic gradients in parallel SGD. Previous
work typically assumes an upper bound on the norm of the input vectors, and achieves
an error bound in terms of this norm. However, in many real applications, the
input vectors are concentrated around the correct output μ, but μ itself has large
norm. In such cases, previous output error bounds perform poorly. In this paper,
we show that output error bounds need not depend on input norm. We provide a method
of quantization which allows distributed mean estimation to be performed with
solution quality dependent only on the distance between inputs, not on input norm,
and show an analogous result for distributed variance reduction. The technique
is based on a new connection with lattice theory. We also provide lower bounds
showing that the communication to error trade-off of our algorithms is asymptotically
optimal. As the lattices achieving optimal bounds under l2-norm can be computationally
impractical, we also present an extension which leverages easy-to-use cubic lattices,
and is loose only up to a logarithmic factor ind. We show experimentally that
our method yields practical improvements for common applications, relative to
prior approaches.

text: With the wider availability of full-color 3D printers, color-accurate 3D-print
preparation has received increased attention. A key challenge lies in the inherent
translucency of commonly used print materials that blurs out details of the color
texture. Previous work tries to compensate for these scattering effects through
strategic assignment of colored primary materials to printer voxels. To date,
the highest-quality approach uses iterative optimization that relies on computationally
expensive Monte Carlo light transport simulation to predict the surface appearance
from subsurface scattering within a given print material distribution; that optimization,
however, takes in the order of days on a single machine. In our work, we dramatically
speed up the process by replacing the light transport simulation with a data-driven
approach. Leveraging a deep neural network to predict the scattering within a
highly heterogeneous medium, our method performs around two orders of magnitude
faster than Monte Carlo rendering while yielding optimization results of similar
quality level. The network is based on an established method from atmospheric
cloud rendering, adapted to our domain and extended by a physically motivated
weight sharing scheme that substantially reduces the network size. We analyze
its performance in an end-to-end print preparation pipeline and compare quality
and runtime to alternative approaches, and demonstrate its generalization to unseen
geometry and material values. This for the first time enables full heterogenous
material optimization for 3D-print preparation within time frames in the order
of the actual printing time.

text: 'We extend the notion of the minimal volume ellipsoid containing a convex
body in Rd to the setting of logarithmically concave functions. We consider a
vast class of logarithmically concave functions whose superlevel sets are concentric
ellipsoids. For a fixed function from this class, we consider the set of all its
“affine” positions. For any log-concave function f on Rd, we consider functions
belonging to this set of “affine” positions, and find the one with the minimal
integral under the condition that it is pointwise greater than or equal to f.
We study the properties of existence and uniqueness of the solution to this problem.
For any s∈[0,+∞), we consider the construction dual to the recently defined John
s-function (Ivanov and Naszódi in Functional John ellipsoids. arXiv preprint:
arXiv:2006.09934, 2020). We prove that such a construction determines a unique
function and call it the Löwner s-function of f. We study the Löwner s-functions
as s tends to zero and to infinity. Finally, extending the notion of the outer
volume ratio, we define the outer integral ratio of a log-concave function and
give an asymptotically tight bound on it.'
