Distinct lattice and charge excitations in AV3Sb5 kagome superconductors

The kagome superconductor family A V 3 Sb 5 ( A = Cs, Rb, K) provides a rich platform for exploring diverse electronic symmetry breaking phenomena, including superconductivity and various forms of density wave orders. Although these compounds share the identical lattice structure...

The Compossibility of Contraries and Determination of Identity in Haribhadrasūri’s Victory-Flag of Non-One-Sidedness (Anekāntajayapatākā)

Abstract The basic thesis of Haribhadrasūri’s Victory Flag of Non-One-Sidedness ( Anekāntajayapatākā , c. 8th century CE) is that any real thing possesses contrary properties such as, in the first instance, existence and nonexistence. It is unsurprising, then, that both classical...

Dams trigger long-term river-floodplain decoupling in dynamic Andean foreland rivers

Andean foreland rivers are preferential sites for ongoing and planned hydroelectric dam construction in the Amazon Basin. These rivers are characterized by high sediment fluxes that drive rapid rates of channel migration, large river-floodplain sediment exchanges, and creatediver...

Causal mediation pathways in continuous postprandial glucose monitoring for type 1 diabetes patients

Abstract Managing postprandial glucose in Type 1 Diabetes Mellitus (T1DM) requires understanding how carbohydrate intake affects glucose through both direct pathways and insulin-mediated compensation. Standard analyses treat insulin as a confounder rather than a mediator, obscuri...

Recent strengthening of eastern Pacific ENSO in the last millennium paleorecord

The Pacific El Niño–Southern Oscillation (ENSO) generates climate extremes that endanger ecosystems, infrastructure, and human well-being worldwide. The response of this system to climate warming is poorly constrained, due both to data scarcity and uncertainties in climate models...

The worst energy policy in the world

The Iran war could serve as a turning point in accelerating the global transition away from fossil fuels: Every additional day that oil and gas prices are high and future supplies are uncertain, wind and solar power—cheaper and more scalable than ever before—grow all the more app...

Universal bound on microwave dissipation in superconducting circuits

Improving the coherence of superconducting qubits is essential for advancing quantum technologies. While superconductors are theoretically perfect conductors, they consistently exhibit residual energy dissipation when driven by microwave currents, limiting coherence times. Here,...

Centralization vs. Decentralization: First Evidence from the Laboratory

The future architecture of financial systems is a subject of contention, with centralized and decentralized governance proponents. Here, we ask the following question. Would the architecture affect the quality of decision making? We propose a game where financial network particip...

Can I Trust You? A Longitudinal Study of the Consequences of Suspicion Among Latina/o Students

Racial/ethnic minority group members vary in the extent to which they are chronically suspicious of the motives behind White people’s positive behavior toward minorities. Chronic suspicion has been shown to shape racial/ethnic minorities’ perception, cognition, emotion, and physi...

Multi-Bin Batching for Increasing LLM Inference Throughput

As large language models (LLMs) grow in popularity for their diverse capabilities, improving the efficiency of their inference systems has become increasingly critical. Batching LLM requests is a critical step in scheduling the inference jobs on servers (e.g. GPUs), enabling the...

Photometallobiocatalytic Asymmetric Radical‐Mediated Cross‐Coupling of Organotrifluoroborate Salts and Pyridotriazoles

ABSTRACT The cooperative integration of photoredox catalysis and metalloenzyme catalysis has emerged as a powerful strategy for enabling stereoselective radical transformations beyond the capabilities of either catalytic mode alone. Herein, we report a photometallobiocatalytic en...

Vector-valued optimal transport: from dynamic to static formulations

Abstract Motivated by applications in classification of vector valued measures and multispecies PDE, we develop a theory that unifies existing notions of vector valued optimal transport, from dynamic formulations (à la Benamou-Brenier) to static formulations (à la Kantorovich). I...

Childcare in Transition: Evidence That Patterns of Childcare Differ by Degree of Market Integration in Northwestern Tanzania

Highlights This study uses novel data on multiple childcare types from both kin and nonkin in two culturally similar communities with varying market integration. It tests the hypothesis that market integration is associated with reduced kin support. Who provides support and the t...

A compilation of global bio-optical in situ data for ocean-colour satellite applications – version four

Abstract. A global in situ dataset for validation of satellite products from the ESA Ocean Colour Climate Change Initiative (OC-CCI) is presented. This version of the compilation, with data starting in 1996, extends to 2025, which is important for the validation of recent algorit...

HarnessingDiamond Surface Features for Dense andAligned NV Ensembles

Abstract Controlling nitrogen doping in diamond is key to advancing nitrogen-vacancy (NV) center devices. We harness the hillock, a typically undesirable surface feature, to incorporate high densities of grown-in, aligned NV centers on a (001)-oriented substrate. Enhanced cathodo...

Long-memory and cyclical link prediction in temporal social networks

<title>Abstract</title> Temporal social networks contain persistent tie activation and periodic communication rhythms, but most link prediction models either emphasize short-term recurrence or rely on black-box embeddings that offer no interpretable summary of temporal structure....

Citrus: Algebraic Reasoning about Superconductor Electronics

We present Citrus, an embedded DSL in the dependently-typed language Agda that formalizes high-level abstractions for specifying and reasoning about superconducting electronics (SCE) circuits. We build on the existing PyLSE language, a Python DSL for writing SCE programs that pro...

Further aspects of supersymmetric Virasoro minimal strings

A supersymmetric version of the Virasoro minimal string was defined some time ago using random matrix model techniques. Several of the special properties of the matrix model that were noted (accessible fully non-perturbatively) underlie features shared by both 0A and 0B versions...

Functional and structural characterization of dendritic spine pathology in a mouse model of tauopathy

SUMMARY Abnormal deposition of the microtubule-associated protein tau has long been associated with neurodegenerative diseases. While spine loss and neuronal death are hallmarks of tauopathy, how pathological tau affects synaptic activity in vivo and whether functional properties...

Curvilinear coordinate systems for 3D design: building cyclidic nets with conformal geometric algebra

Abstract We introduce various parametric techniques to construct and manipulate triply orthogonal curvilinear lattices. Using principal contact tangent elements and the rationalization of spheres through conformal transformations, we detail their constraints and provide an invers...
