Advanced Science, EarlyView.Pancreatic neuroendocrine tumors frequently silence MEN1 through epigenetic mechanisms. Here, SIRT7 recruits DNMT1 to the MEN1 promoter, drives hypermethylation, and enhances DNA repair. Inhibiting SIRT7 restores MEN1, reduces MRN complex abundance, impairs double‐strand break repair, and sensitizes PanNET models to radiation, supporting SIRT7 as a ...

A Comprehensive BLE-Compliant Dataset for Indoor Positioning Systems
IEEE Open Journal of the Communications SocietyThe Direction Finding (DF) feature in Bluetooth Low Energy (BLE) 5.1 has made the technology an increasingly attractive choice for Indoor Positioning Systems (IPS), as it allows devices to estimate the Angle of Arrival (AoA) of incoming signals.

Advanced Science, EarlyView.A zebrafish model carrying an identical human RHO S334X allele reveals two independent genetic layers shaping retinitis pigmentosa (RP) severity: a protective 3‐bp cis‐regulatory insertion that attenuates transgene expression, and a dominant trans‐acting modifier that restores a severe phenotype.

Enhancing Maturation of Human Neuromuscular Organoids via Electrical Stimulation
Advanced Science, EarlyView.A framework for on‐demand and non‐invasive exposure of human neuromuscular organoids (NMOs) to electrical stimuli is established to promote their maturation. The robustness and effectiveness of different stimulation regimes are evaluated via thorough characterization of organoid tissue structure and contraction capacity. Chronic electrical stimulation,

Implementation of direction finding with frequency diverse array
, 2017 Frequency Diverse Array (FDA) is a recent concept with lots of advantages that are emerged for the radar applications. In order to implement FDA practically, Linear Frequency Modulation (LFM) based FDA is recently offered. A tunable oscillator with delay

Advanced Science, EarlyView.Whole‐genome analysis of 1,054 chickens reveals three ancestral sources (NWC, SYA, and SHF) with distinct temporal entry patterns into the Tibetan Plateau. Route‐specific selection scans, calibrated against a demographic null, suggest complementary functional enrichments—vascular homeostasis (NWC), calcium signaling and cardiac adaptation (SYA), and ...
