Advanced Science, EarlyView.To model a nutrient‐restricted tumor microenvironment, breast cancer cells were adapted to low glucose and glutamine levels. In the adapted cells, BRD4‐driven enhancer activation increases pro‐invasive EDN1 expression, facilitated by ATF3/c‐JUN and reinforced by enhancer RNA.

Pressure‐Tuned Superconducting Dome and Persistent Charge‐Density‐Wave Order in NdSeTe2
Advanced Science, EarlyView.NdSeTe2 exhibits an unusual pressure‐tuned phase diagram in which charge‐density‐wave order does not disappear at optimal superconductivity. Instead, Raman spectroscopy reveals a transformation from long‐range to short‐range correlations that remain invisible to resistivity and persist across the entire superconducting dome.

SWITCHED-CAPACITOR FIR FILTERS.
, 1987 The design of simple FIR filters with equally-spaced zeros on the z-domain unit circle is presented. The proposed circuits can be realized by stray-insensitive switched-capacitor (SC) techniques and are well suited to be combined with recursive SC ...

SWITCHED-CAPACITOR ACTIVE FILTER DESIGN AND SIMULATION
, 1981 With the advantages of MOS monolithic technology in mind, Switched-Capacitor (SC) filter design and simulation are studied in this research. For SC circuit design, Shunt SC, bilinear, and LDI z-Transform methods are discussed. A practical design example,

Advanced Science, EarlyView.A novel bias‐programmable shortwave infrared (SWIR) vision sensor is developed using multi‐junction colloidal quantum dots (QDs). Under varying applied voltage, the back‐to‐back rectifying junctions effectively tune trapping centers to switch the device between high‐speed photodetector and persistent synapse modes.

Prion‐Like Protein LENG8‐Mediated Nucleation Drives Stress Granule Assembly
Advanced Science, EarlyView.LENG8 is a newly identified stress granule (SG) nucleator required for SG assembly. Following stress, nuclear LENG8 granules disassemble, allowing LENG8 to translocate into the cytoplasm and form independent nucleation foci. These foci fuse with canonical early G3BP1/TIA1 seeds via LENG8‐TIA1 binding to drive SG maturation.
