Displacement and Vibration Measurements with Interferometers: Benchmark Configurations, Performance, and R&D Opportunities

open access: yesAdvanced Photonics Research, EarlyView.
Self‐mixing interferometry is a powerful technique that brings together the exceptional sensitivity of phase measurements with the unequalled simplicity of the self‐mix configuration based on modulation of the cavity field induced by the return from the target. According to the selected measurand, displacement or vibration, and to the analog of digital

MicroRNA‐Enriched Plant‐Derived Exosomes Alleviate Colitis by Modulating Systemic Immunity, Metabolic Homeostasis, and Gut Microbiota

open access: yesAdvanced Science, EarlyView.
Herbal medicine, with its multicomponent and multitarget potential, is often studied primarily for traditional forms, especially phytochemicals. Currently, ulcerative colitis lacks natural, low‐toxicity therapies, yet emerging research highlights plant‐derived exosomes as a promising option.

Visible‐Light‐Activated Multi‐Color Tunable Time‐Dependent Afterglow Triggered by Variable Conjugation Effects via the Transformation of Matrix

open access: yesAdvanced Science, EarlyView.
Three carbon dots (CDs)‐based composites are synthesized via heat treatment of phenylenediamine derivatives with urea. These composites exhibit time‐dependent afterglow across most of the visible spectrum under visible‐light excitation. The matrix modulation strategy regulates the degree of conjugation in the composites, effectively tuning their ...

Heterogeneous computing at INFN-T1 [PDF]

open access: yesEPJ Web of Conferences
At INFN-T1 we recently acquired some nodes with ARM and RISC-V CPUs to understand the experiment level of readiness on new hardware solutions and to test our production pipelines. After some initial testing, ARM resources entered the standard farm, since

June 27th, 2017 [PDF]

open access: yes, 2017
Historically memory models for multiprocessors have not been designed deliberately but have just emerged. Practically every microarchitectural optimization, which is transparent in a single threaded setting, becomes programmatically visible in a ...

Sulfur‐Embedded Pure Green Multiple Resonance TADF Emitters: Optimizing Photophysical and Electroluminescent Properties

open access: yesAdvanced Science, EarlyView.
Sulfur atoms are inserted into the multiple‐resonance thermally activated delayed fluorescence framework for developing pure green emitters. The analogous isomers present distinguishing photophysical and electroluminescent properties. The better emitter‐based non‐sensitized device exhibits a maximum external quantum efficiency of 36.4% and a remarkable

Effect of Molecular Aggregation on Photophysical Properties of Organoboron/Nitrogen‐ and Carbonyl/Nitrogen‐Based Two Multi‐Resonant Emitters

open access: yesAggregate, EarlyView.
By using MD‐QC simulation method, it is proven that molecular aggregation via π–π interactions (in DNK) is the primary cause of shoulder peak enhancement, leading to a 0.16 eV spectral broadening. In contrast, DBN's stable emission stems from suppressed aggregation due to steric hindrance.
