On spatially-adaptive intensity estimation for spatial point processes

Abstract Spatial adaptation plays an important role in intensity estimation for spatial point processes, especially in the presence of heterogeneity, where the required degree of smoothing varies across the domain. In this paper, we propose a spatially-adaptive intensity estimati...

A Wizard-of-Oz Shuttle as an Experimental Platform for Research on Future Automated Public Transport

Automated public shuttles have the potential to improve road safety, transport accessibility, and passenger experience. However, before such systems can be widely deployed, their sensing, interaction, monitoring, and assistance functions must be systematically designed and evalua...

DNA-encoded Ugi reactions in the organic phase: Lactam synthesis and use of cyclic ketones as scaffold-providing oxo-component

Isocyanide multicomponent reactions such as the Ugi fourcenter reaction are attractive for DNA-encoded library design because they allow for synthesizing diverse peptidomimetic and heterocyclic scaffolds from large numbers of simple and readily available starting materials. DNA a...

Dynamical mean-field theory for dense spin systems at finite temperature

In recent years, a method for computing spin dynamics at infinite temperature (spinDMFT) was developed. It utilizes the ideas of dynamical mean-field theory for fermions: single-site approximation and a self-consistency condition to approximate time-dependent spin correlations. I...

Modular Triethylene Glycol Decouples Antimicrobial Potency from Cytotoxicity in Membrane-Active Drugs

Abstract Cationic membrane-active drugs are an important focus of antibiotic research, yet their potential is often limited by poor selectivity. Here, we establish steric protection of cations by modular triethylene glycol as a chemical design framework to decouple antimicrobial...

Experimental Signature of Transient Symmetry Breaking in a Cavity Dirty-Limit Superconductor

Abstract Transient states of matter far from equilibrium may exhibit physical properties beyond those allowed by the equilibrium-state crystalline symmetries. We explore ultrafast and direct electronic excitations of transient states in a dirty-limit superconductor with time-reso...

Fine Asymptotics of the Magnetization of the Annealed Dilute Curie-Weiss Model

Abstract We consider the dilute Curie-Weiss model of size N , which is a generalization of the classical Curie-Weiss model in which the dependency structure between the spins is encoded not by the complete graph but by the (directed) Erdős-Rényi graph on N vertices in which every...

One‐Step Access to Ultra‐Bright Macrocyclic Oligo‐BODIPYs Featuring Long‐Lived Cyclic Excitons

ABSTRACT The controlled organization of chromophores into defined assemblies with collective photophysical properties is a key concept for natural and artificial photonic systems. A template‐free, one‐step synthesis affords a series of methylene‐bridged macrocyclic oligo‐BODIPYs...

Unraveling Individual Second-Language Acquisition in Late Bilingual Children With and Without Suspected Developmental Language Disorder: A Longitudinal Approach

Purpose: Research in bilingual language acquisition has experienced a shift toward more individual-focused analyses within longitudinal studies. The aim of the present study was to retrospectively investigate early markers for suspected developmental language disorder (DLD) in la...

Dynamic self-polarization of the nuclear spins in a GaAs quantum well

We demonstrate the self-polarization regime of nuclear spins, originally predicted in 1972 by Dyakonov and Perel and achieved here by lattice temperature reduction into the millikelvin range. We first identify a gallium arsenide-based quantum well structure as highly suited by de...

Enhancing Training Effectiveness Through Graphic Recording: Mitigating Information Overload in Human Resource Development

ABSTRACT This study investigates the efficacy of graphic recording, a real‐time visual facilitation technique, in mitigating information overload and enhancing training effectiveness within human resource development (HRD) and vocational education and training (VET) contexts. A q...

Trends in optimizing antibacterial cationic amphiphiles

Cationic amphiphiles are investigated as antibacterials, yet their potential is often limited by host-cell toxicity. Bacterial and mammalian membranes share core physicochemical features that promote interactions with cationic amphiphiles. Selectivity is realistically understood...

A crystalline uranium Fischer-type carbyne

Abstract Since their discovery in 1973, transition metal Fischer carbynes have become a foundational class of metal–carbon triple bond in organometallic chemistry. However, even though the uranium Fischer carbyne bonding motif has been a fundamental target in f -element chemistry...

Directed Surface Immobilization of Coordination Cages for Host–Guest Studies

Abstract Self-assembled coordination cages are bioinspired host–guest systems mimicking natural nanoconfinements and their functions as receptors and reaction compartments. While such systems are conventionally studied in solution or as bulk materials, the examination of surface-...

Bayesian-Guided Cooperative RL Beamforming for Wireless Adversarial User Detection

In next-generation wireless networks, communication systems are expected to go beyond simple data transmission and simultaneously provide high data rates, efficiency, and security. This requirement has motivated the extensive adoption of machine learning methods to develop intell...

Covalent-Allosteric Akt Inhibitors: Targeting Akt3 through Molecular Hybridization and Expanding the Isoform-Selective Toolbox

Akt is a central serine/threonine kinase in the PI3K/Akt/mTOR pathway that regulates cell survival, growth, and metabolic homeostasis. Although Akt1, Akt2, and Akt3 share high sequence homology, they perform distinct physiological and pathological functions, motivating the develo...

Evaluating the Value of Topology-Aware Features for Cyber-Physical Grid Monitoring: Detection, Localization, and End-to-End Latency

Distinguishing cyber false-data-injection attacks (FDIAs) from legitimate physical disturbances requires accurate detection, localization, and sufficiently fast end-to-end processing. We evaluate the marginal value of explicit topology-relational features across a synthetic 5-bus...

Interplay of Umklapp scattering and Sb–Au hybridization in surface-reconstructed Sb/Au(111)

Abstract Surface reconstructions induced by atomic adsorption can strongly reshape metallic surface states, providing a direct pathway to tune their electronic structure. Using angle-resolved photoemission spectroscopy, we investigate the electronic structure of Sb/Au(111) across...

F-Convexity of Real Functions

Let F be a family of sets in Rd. A set M⊂Rd is called F-convex if for any points x,y∈M there is a set F∈F such that x,y∈F and F⊂M. A function f:R→R is called F-convex if its epigraph is F-convex. In this paper we investigate various F-convexities for real functions
