InstructTime++: Time Series Classification with Multimodal Language Modeling via Implicit Feature Enhancement

Most existing time series classification methods follow a discriminative modeling paradigm that directly maps input sequences to one-hot encoded class labels. Although effective, this paradigm suffers from two inherent limitations: it is difficult to effectively exploit contextua...

Ethics as Technology: AI Ethics as Technologies of Governance and the Case for STS

Abstract Artificial Intelligence (AI) has become a central focus of ethical deliberation in reports, guidelines, and official statements issued by technology companies, governments, and international organizations. This paper analyzes five influential documents representing the b...

Analyzing Residential Speeding Using Connected Vehicle Data: A Case Study in the Charlottesville, VA Area

This study uses connected vehicle data to analyze speeding behavior on residential roads. A scalable pipeline processes trajectory data and supplements missing speed limits to generate summaries at OpenStreetMap’s way ID level. The findings reveal a highly skewed distribution of...

Passive cooling to mitigate climate-induced performance losses in photovoltaics

Accelerating climate change is intensifying thermal stress on solar photovoltaics, as their efficiency and yield are directly constrained by rising ambient temperatures and increasing exposure to extreme heat. Scalable and robust thermal management strategies are therefore essent...

Surface Segregation in Compositionally Complex Ag‐Au‐Pd‐Pt Solid Solutions: Insights From High‐Throughput Experimentation and Atomistic Simulations

ABSTRACT The activity of compositionally complex electrocatalysts depends on their surface composition, which can be different from the volume composition. In solid solutions, surface segregation under vacuum can be estimated based on the surface energy of the constituent element...

Accessible in theory, inaccessible in practice: a user-centered evaluation of disability inclusion in humanitarian WASH facilities in Gaza displacement camps

Abstract Background Persons with disabilities in displacement settings face persistent barriers to safe, dignified, and independent access to water, sanitation, and hygiene (WASH) facilities. Evidence on functional accessibility in conflict-affected Gaza is limited. This study ev...

Golden retrievers: Older adults solve single-digit arithmetic via fact retrieval.

Arithmetic skills are crucial for mastering everyday life up to old age. However, it is unknown whether the interplay of different task characteristics affects arithmetic performance differently in older and younger adults. The aim of this study was to investigate whether older a...

Prevalence and associated factors of nomophobia among the medical and university students of Bangladesh

Abstract Background Nomophobia, characterised by the dread or anxiety of being without access to a mobile phone, has become an increasing behavioural issue among young adults, especially university students. Excessive reliance on smartphones has been linked to psychological suffe...

The Compton Effect. A Tale of Two Encounters

The Compton effect is conventionally represented as a collision between a photon and an electron, with the observed wavelength shift determined by energy--momentum conservation and scattering geometry. This article revisits the event from a complementary perspective. Beginning fr...

Automated electrostatic characterization of quantum dot devices in single- and bilayer heterostructures

Abstract As quantum dot (QD)-based spin qubits advance toward larger, more complex device architectures, rapid, automated characterization and data analysis tools become critical. The orientation and spacing of transition lines in a charge stability diagram (CSD) contain a finger...

Metasurface‐Based Terahertz Three‐Dimensional Holography Enabled by Physics‐Informed Neural Network

ABSTRACT Artificial intelligence has revolutionized optical device design, overcoming the efficiency bottlenecks of traditional methods. For holographic metasurfaces, conventional iterative algorithms suffer from time‐consuming iterations and convergence stagnation, especially as...

Phosphorylation Protects Oncogenic RAS from LZTR1-Mediated Degradation

Oncogenic KRAS and NRAS mutations are common in hematologic malignancies, but how they signal is less well characterized than in carcinomas. To uncover novel RAS biology and potential therapeutic vulnerabilities, we employed a multi-omics screening approach in multiple myeloma to...

Measuring what matters: a rasch-validated instrument for functional sexual and reproductive health literacy among Ghanaian adolescents

Abstract Background Functional sexual and reproductive health (SRH) literacy is fundamental to informed decision-making among adolescents. Yet existing measures hardly address the needs of low-literate populations in Sub-Saharan Africa. This study developed and validated a test o...

The impact of stochastic sea ice perturbations on seasonal forecasts

Abstract. Sea ice ensemble forecasts can be highly underdispersive, meaning that the ensemble spread is notably lower than the average forecast error. One common strategy to address underdispersion is to add stochastic perturbations to the forecasts. We detail the implementation...

Functional fractionation of large-scale brain networks in the human subcortex

Brain network mapping plays a crucial role in advancing our understanding of human brain organization and the neuroanatomic foundations of cognition. Historically, the identification of large-scale brain networks has focused on the cerebral cortex. Some cortical networks have bee...

Anatomical white matter tracts span the cortical hierarchy to support cognitive diversity

Long-range white matter (WM) tracts support cognition by enabling communication between distant cortical regions, which are organized along a hierarchy defined by the sensorimotor-to-association (S-A) axis. However, it remains unknown how WM tracts are positioned within the corti...

Perturbative Chern-Simons invariants from non-acyclic flat connections

We give a short review of our construction of a higher-loop perturbative invariant of framed 3-manifolds, generalizing the perturbative Chern- Simons invariant of Witten-Axelrod-Singer, associated to an acyclic flat connection, to an invariant given by the integral of a certain “...

The Canonical Triple-Graph: A Structural Organization of the Positive Integers

The Canonical Triple-Graph (CTG) The set of positive integers is fixed, yet its familiar linear ordering conceals a latent hierarchical structure. This paper describes that structure through an admissible associator on the odd integers: n = (2ᵏm − 1) / 3, defined whenever 2ᵏm ≡ 1...

The green divide: renewable energy shaping community coherence

While renewable energy (RE) is crucial for the green transition, this contribution sheds light on how the process of proposing and implementing RE projects negatively impacts community coherence. The paper discusses the complexities of implementing RE projects in local communitie...

Distilling the WhiSCCI: Development of the White Short Critical Consciousness Index

Critical consciousness (CC) describes a system of awareness and action to liberate marginalized communities from oppressive systems. Modern scholarship often portrays CC as a tripartite model featuring an awareness of oppressive systems, the motivation to change them, and the act...
