Pyridine‐dicarbonitriles acceptor engineering in multi‐resonance thermally activated delayed fluorescence with hybridized short‐ and long‐range charge transfer for high‐performance electroluminescence

open access: yesFlexMat, EarlyView.
Pyridine‐dicarbonitrile units integrated into a multiple‐resonance core engineer the excited state through cooperative short‐range charge transfer (SRCT) and long‐range charge transfer (LRCT), thereby enhancing the spin‐flipping process. Abstract Multi‐resonance (MR) thermally activated delayed fluorescence (TADF) materials exhibit narrowband emission ...

Posture-aware standing stability control of a bipedal wheel-legged robot using hybrid adaptive optimization

open access: yesFranklin Open
Standing stability in bipedal wheel-legged robots is strongly influenced by posture-dependent inertia, gravity torque, and actuator constraints, which makes controller tuning and posture selection highly coupled. Most existing approaches tune controllers

Tailoring hot‐exciton emitter via an accelerated reverse intersystem crossing process for deep‐blue organic light‐emitting diodes with an external quantum efficiency approaching 16% at 1000 cd m−2 and a CIEy of 0.027

open access: yesFlexMat, EarlyView.
A tailor‐made deep‐blue emitter with an accelerated process with a rate of 4.4 × 109 s−1 achieves a deep‐blue organic light‐emitting diodes with external quantum efficiency of 15.7% at a practical brightness of 1000 cd m−2 with an extremely small CIEy coordinate of 0.027. Abstract Achieving high‐efficiency, saturated‐color, and stable deep‐blue organic

Manipulation of organic triplet states for achieving multifunctional luminescence: Mechanisms, strategies, and applications

open access: yesFlexMat, EarlyView.
Triplet‐state regulation strategy involves the relaxation pathways of triplet excitons and the underneath structure property relationships. This review combines recent studies on relaxation principles, energy transfer, anti‐Kasha behaviors, and functional applications of triplet excitons.

The single-mass variable flavor number scheme at three-loop order

open access: yesJournal of High Energy Physics
The matching relations in the unpolarized and polarized variable flavor number scheme at three-loop order are presented in the single-mass case. They describe the process of massive quarks becoming light at large virtualities Q 2.

Epigenetic Regulation in the Pathogenesis of Renal Inflammation: Insights and Therapeutic Potentials

open access: yesiNew Medicine, EarlyView.
ABSTRACT Renal inflammation is a common pathological process in various kidney diseases, often initiated by factors such as toxins, ischemia, or autoimmune reactions. This inflammatory response can result in structural damage and a rapid decline in renal function.

A Detailed Analysis of Contemporary ARM and x86 Architectures [PDF]

open access: yes, 2013
RISC vs. CISC wars raged in the 1980s when chip area and processor design complexity were the primary constraints and desktops and servers exclusively dominated the computing landscape.

Growing Through It: A Longitudinal Examination of Body Dissatisfaction, Mental Health, and Resilience During Adolescence

open access: yesJournal of Adolescence, EarlyView.
ABSTRACT Introduction Research indicates adolescence, specifically puberty, is a critical period of psychological and physiological development. It is well known that body image is a key aspect of developmental psychology impacting mental health. Yet little is known about the buffering effects of resilience to moderate the relationship between body ...
