Quantum low-density parity-check (qLDPC) codes are promising for realizing scalable faulttolerant quantum computation due to their potential for low-overhead protocols. A common approach to decoding qLDPC codes is to use the belief propagation (BP) decoder, followed by a postprocessing step to enhance decoding…

In numerous practical scenarios, signals invariably encounter degradation due to noise, distortion, or various forms of interference. This corruption significantly compromises the integrity of the phase information. Phase retrieval endeavors to reconstruct the original signal, R n or C n , from a set of measurements, b…

We propose a simple proof of the worst-case iteration complexity for the Difference of Convex functions Algorithm DCA for unconstrained minimization, showing that the global rate of convergence of the norm of the objective function's gradients at the iterates converge to zero like o(1/k). A small example is also…

This paper introduces an efficient perturbed difference-of-convex algorithm (pDCA) for computing d-stationary points of an important class of structured nonsmooth difference-of-convex problems. Compared to the principal algorithms introduced in [J.-S. Pang, M. Razaviyayn, and A. Alvarado, Math. Oper. Res. 42(1):95–118…

We address the problem of computing stationary points for non-smooth, non-convex optimization problems. While this topic is well studied in the smooth setting, fewer algorithmic and theoretical results exist for the non-smooth case. Within Difference-of-Convex functions (DC) programming, the well-known DC Algorithm…

Transmission Topology Optimization has great potential to improve efficiency and flexibility of grid operations through non-costly switching actions, but previous approaches struggle with runtime performance and scalability. In this work, we present an optimization approach that leverages GPU acceleration to speed up…

With the rapid growth of data center (DC) energy consumption and the large-scale integration of renewable energy, DCs increasingly face time-varying power upper-bound constraints jointly shaped by grid power supply capability, renewable energy fluctuations, and demand response mechanisms. Meanwhile, DC power…

DPC (density peaks clustering) algorithm has garnered widespread attention due to its novelty and superior performance. However, it is sensitive to the arbitrary cutoff distance, and its very efficient assignment strategy is prone to leading “domino effect”. Although FKNN-DPC and other variants addressed DPC’s…

We present a simple randomized algorithm that can efficiently maintain a (∆ + 1) coloring as the graph undergoes edge insertion and deletion updates, where ∆ denotes an upper bound on the maximum degree. A key advantage is the algorithm's ability to process many updates simultaneously, which makes it naturally…

Biological pathway analysis often requires identifying interventions that block reachability to an undesirable state, such as a disease-associated module, toxic byproduct, or adverse phenotype, while preserving reachability among essential biological functions. Motivated by this setting, we study the Reachability…

Decompressive craniectomy (DC) is a critical intervention for managing severe traumatic brain injury (sTBI) in children when medical therapy fails, but the optimal timing remains unclear. This study evaluated the association between different DC timing and short-term outcomes in pediatric sTBI in Germany. A…

Atomistic simulations provide essential mechanistic insights into chemical processes, yet many important phenomena in chemistry and materials science occur on timescales that are inaccessible to molecular dynamics. Existing computational approaches force a choice between atomic resolution on relatively short timescales…

A framework for catalysis based on categorical aperture selection rather than temporal acceleration is presented. Traditional catalysis theory describes catalysts as agents that accelerate reactions by lowering activation energies, implicitly treating time as the fundamental variable and reaction rate enhancement as…

As mobile communication systems continue to evolve to support higher data rates, ultra-low latency, and greater reliability, the effective management of Physical Cell Identities (PCI) becomes increasingly important. The pool of available identifiers is limited-504 in fourth-generation networks and 1008 in…

Multivalent lectin-glycan interactions (MLGIs) are widespread and vital for pathogen infection, cell-cell communication and immune regulation, making them attractive therapeutic targets. Despite significant efforts, research progress in MLGI targeting therapeutics remain limited, due to incomplete understanding of the…

Most current methods for goal-directed action selection in the face of changing goals and contingencies require DNNs or LLMs. Therefore they are less suited for implementation in edge devices, where low energy-consumption is imperative. The brain shows that similar functionality can be produced with just 20W, even with…

How developing organisms respond to a changing environment is a fundamental question. Pollutants and temperature are major environmental factors. Using the bristle patterning of Drosophila as a model system, we observed that cold temperature and methotrexate, a medical drug that contaminates wastewaters, increase…

The energy hole problem is a significant challenge in wireless sensor networks (WSN) that use multi-hop routing protocols. Nodes near the base station (BS) typically experience higher energy consumption due to higher data traffic, resulting in faster network energy depletion and creating an energy hole near the BS. To…

Machine olfaction—the artificial replication of the sense of smell—faces significant challenges due to the absence of large, standardized training datasets. Unlike vision, language, and audio models, which benefit from extensive corpora such as ImageNet, GLUE, and AudioSet, olfaction lacks scaled equivalents and…

With the surge in sequencing data generated from an ever-expanding range of biological studies, designing scalable computational techniques has become essential. One effective strategy to enable large-scale computation is to split long DNA or protein sequences into k-mers, and summarize large k-mer sets into compact…

DNA storage is a developing field that uses DNA to archive digital data owing to its superior information density and stability. Although DNA storage has been performed on a significant scale, challenges arise from the synthesis and sequencing of data-encoded oligonucleotides. Synthesis of DNA introduces significant…

Globally all power utilities are striving to cater to the ever-increasing demand for electrical energy by either adding new transmission lines or by optimizing the already existing ones with an objective of transmitting higher degrees of power. The construction of new transmission infrastructure, however, is limited by…

The use of Deep Brain Stimulation (DBS) on the ventral capsule/ventral striatum (VCVS) has therapeutic potential for patients with refractory psychiatric disorders, but clinical success is impeded by the need for a time-consuming and trial-and-error process when setting the parameters, this process relying on…
