Heat treatment technique and fuelwood density shape silcrete flake-edge geometry

Silcrete heat treatment was a transformative technological innovation in the Middle Stone Age, enabling toolmakers to improve the flaking properties of this raw material. Recent research has highlighted that silcrete heat treatment is not a uniform process, different silcrete sou...

Accuracy of commercial pollen forecasts in the United States

Approximately 80 million Americans suffer from seasonal pollen allergies, and many rely on commercial pollen forecasts to guide exposure reduction and medication timing. However, these forecasts are proprietary, and their accuracy has never been comprehensively evaluated. Here, w...

Daily Workload and Evening Detachment: Impact of Supervisor Support for Recovery

Our study examines the role of leaders in employee recovery. We hypothesize that supervisor support for recovery (between-person) will buffer the impact of daily workload (within-person) on evening psychological detachment (within-person). We tested this hypothesis with a 7-day e...

Stakeholder proximity and non-GAAP earnings disclosure

Purpose This study examines the relation between stakeholder proximity and firms’ use of earnings measures not prepared in accordance with generally accepted accounting principles (GAAP), commonly referred to as non-GAAP earnings. Design/methodology/approach Stakeholder proximity...

Electronic Dimensionality Control of Exciton Localization in Lead‐Free Copper Halide Perovskite Derivatives for Full‐Color, High‐Fidelity, and Circadian‐Tunable White‐Light Emission

ABSTRACT Rare‐earth‐free white light–emitting diodes (WLEDs) require emissive materials that simultaneously deliver high photoluminescence efficiency, spectral complementarity, and environmental stability. Here, an electronic‐dimensionality‐guided design strategy is reported for...

Spinal interoceptive pathways as therapeutic targets in depression

Interoception is commonly defined as the process by which the nervous system senses, interprets and integrates signals from the body. Converging theoretical frameworks propose that signals about bodily states are conveyed by spinal interoceptive pathways (SIPs) to a distributed i...

Species-specific behaviors drive the initiation and maintenance of snapping shrimp-goby mutualisms

Abstract Animals in obligate mutualisms perform behaviors to indicate their willingness to form partnerships and to communicate their quality to potential partners. Obligate mutualisms are difficult to study since they are formed quickly and remain in place until one partner is l...

Machine learning for predictive maintenance in energy storage systems: A systematic review of health prediction, fault diagnosis, and deployment challenges

This research examines the function of machine learning in the predictive maintenance of energy storage systems (ESS), highlighting its capacity to improve system reliability, efficiency, and longevity. The text commences with a summary of the foundational principles of predictiv...

Neural Correlates of the Acceptable Noise Level and Self-Reported Listening Skills in Young Adults With Autism Spectrum Disorder

Purpose: This brain–behavior study investigated the relationship between auditory sensory gating and noise acceptance in listeners with and without autism spectrum disorder (ASD). Relationships between self-reported listening skills and auditory sensory gating were also examined....

Migration of lithium ions and effects of defects in garnet-type solid-state electrolyte Li7La3Zr2O12

As a garnet-type solid electrolyte in solid-state lithium-ion batteries, the cubic phase of Li7La3Zr2O12 (LLZO) has attracted significant attention due to its high ionic conductivity. Using ab initio density-functional theory, we performed calculations to explore the migration pa...

Laser powder directed energy deposition fabrication and tensile sandwich evaluation of Ti64-C103-GRCop-42 functionally graded materials

Functionally graded materials (FGMs) provide an avenue to combine two alloys with different primary benefits such as Ti–6Al–4 V (Ti64) and GRCop-42, which expands the bounds of engineering design possibilities. However, direct grading between Ti64 and GRCop-42 via laser powder di...

Bilayer Spectral Engineering of Bi 3 + /Te 4 + ‐Doped Cs 2 ZrCl 6 for Human‐Centric Solid‐State Lighting

ABSTRACT Lead‐free vacancy‐ordered double perovskites are promising phosphors for solid‐state lighting, yet achieving white‐light emission with simultaneously high color fidelity, tunable correlated color temperature (CCT), and controllable circadian‐relevant optical response rem...
