A new construction of universal spaces for asymptotic dimension | For each $n$, we construct a separable metric space $\mathbb{U}_n$ that is
universal in the coarse category of separable metric spaces with asymptotic
dimension ($\mathop{asdim}$) at most $n$ and universal in the uniform category
of separable metric spaces with uniform dimension ($\mathop{udim}$) at most
$n$. Thus, $... | 0 | 0 | 1 | 0 | 0 | 0 |
A Comprehensive Framework for Dynamic Bike Rebalancing in a Large Bike Sharing Network | Bike sharing is a vital component of a modern multi-modal transportation
system. However, its implementation can lead to bike supply-demand imbalance
due to fluctuating spatial and temporal demands. This study proposes a

On Thin Air Reads: Towards an Event Structures Model of Relaxed Memory | To model relaxed memory, we propose confusion-free event structures over an
alphabet with a justification relation. Executions are modeled by justified
configurations, where every read event has a justifying write event.
Justification alone is too weak a criterion, since it allows cycles of the kind
that result in so... | 1 | 0 | 0 | 0 | 0 | 0 |
Tensor ring decomposition | Tensor decompositions such as the canonical format and the tensor train
format have been widely utilized to reduce storage costs and operational
complexities for high-dimensional data, achieving linear scaling with the input
dimension instead of exponential scaling. In this paper, we investigate even

Combining Information from Multiple Forecasters: Inefficiency of Central Tendency | Even though the forecasting literature agrees that aggregating multiple
predictions of some future outcome typically outperforms the individual
predictions, there is no general consensus about the right way to do this. Most

QCD-Aware Recursive Neural Networks for Jet Physics | Recent progress in applying machine learning for jet physics has been built
upon an analogy between calorimeters and images. In this work, we present a
novel class of recursive neural networks built instead upon an analogy between
QCD and natural languages. In the analogy, four-momenta are like words and the

A conjecture on $C$-matrices of cluster algebras | For a skew-symmetrizable cluster algebra $\mathcal A_{t_0}$ with principal
coefficients at $t_0$, we prove that each seed $\Sigma_t$ of $\mathcal A_{t_0}$
is uniquely determined by its {\bf C-matrix}, which was proposed by Fomin and
Zelevinsky in \cite{FZ3} as a conjecture. Our proof is based on the fact that

Attacking Similarity-Based Link Prediction in Social Networks | Link prediction is one of the fundamental problems in computational social
science. A particularly common means to predict existence of unobserved links
is via structural similarity metrics, such as the number of common neighbors;
node pairs with higher similarity are thus deemed more likely to be linked.
However, a ... | 1 | 0 | 0 | 0 | 0 | 0 |
On algebraic branching programs of small width | In 1979 Valiant showed that the complexity class VP_e of families with
polynomially bounded formula size is contained in the class VP_s of families
that have algebraic branching programs (ABPs) of polynomially bounded size.
Motivated by the problem of separating these classes we study the topological

A lightweight thermal heat switch for redundant cryocooling on satellites | A previously designed cryogenic thermal heat switch for space applications

Fast Automatic Smoothing for Generalized Additive Models | Multiple generalized additive models (GAMs) are a type of distributional

Stabilization and control of Majorana bound states with elongated skyrmions | We show that elongated magnetic skyrmions can host Majorana bound states in a
proximity-coupled two-dimensional electron gas sandwiched between a chiral
magnet and an $s$-wave superconductor. Our proposal requires stable skyrmions
with unit topological charge, which can be realized in a wide range of

Meromorphic functions with small Schwarzian derivative | We consider the family of all meromorphic functions $f$ of the form $$

Measure-geometric Laplacians for discrete distributions | In 2002 Freiberg and Zähle introduced and developed a harmonic calculus for

Optimal heat transfer and optimal exit times | A heat exchanger can be modeled as a closed domain containing an

A Semantics Comparison Workbench for a Concurrent, Asynchronous, Distributed Programming Language | A number of high-level languages and libraries have been proposed that offer

Simulating Linear Logic in 1-Only Linear Logic | Linear Logic was introduced by Girard as a resource-sensitive refinement of
classical logic. It turned out that full propositional Linear Logic is
undecidable (Lincoln, Mitchell, Scedrov, and Shankar) and, hence, it is more
expressive than (modalized) classical or intuitionistic logic. In this paper we

Adaptive Network Coding Schemes for Satellite Communications | In this paper, we propose two novel physical layer aware adaptive network

Optimal control of elliptic equations with positive measures | Optimal control problems without control costs in general do not possess
