In particular, the modulation of photochromic behavior on demand for such materials is of fundamental importance, but it remains a formidable challenge. Here, we report a facile and effective strategy to engineer controllable photochromic properties by v

Researchers Steal Data From Air-Gapped Systems Using Fan Vibrations A team of Israeli researchers led by Mordechai Guri, the head of R&D at the Ben-Gurion University of the Negev, has unveiled a new method of exfiltrating data from air-gapped computers via fan vibrations. It's the latest in a series of data-stealing tactics Guri and his team have demonstrated, all of them focused on methods of invisibly transmitting data from computers that are supposed to be iso

Here, we theoretically and experimentally investigate self-testing of nonprojective quantum measurements. That is, how can one certify, from observed data only, that an uncharacterized measurement device implements a desired nonprojective positive-operator valued measure (POVM). We consider a prepare-and-measure scen

Super-resolution nanoscopy by coherent control on nanoparticle emission Super-resolution nanoscopy based on wide-field microscopic imaging provided high efficiency but limited resolution. Here, we demonstrate a general strategy to push its resolution down to ~50 nm, which is close to the range of single molecular localization microscopy, without sacrificing the wide-field imaging advantage. It is done by actively and simultaneously modulating the characteristic emiss

The deubiquitinase UCHL1 regulates cardiac hypertrophy by stabilizing epidermal growth factor receptor Pathological cardiac hypertrophy leads to heart failure (HF). The ubiquitin-proteasome system (UPS) plays a key role in maintaining protein homeostasis and cardiac function. However, research on the role of deubiquitinating enzymes (DUBs) in cardiac function is limited. Here, we observed that the deubiquitinase ubiquitin C-terminal hydrolase 1 (UCHL1) was significantly up-regulated in agonist-sti

Three-dimensional vectorial holography based on machine learning inverse design The three-dimensional (3D) vectorial nature of electromagnetic waves of light has not only played a fundamental role in science but also driven disruptive applications in optical display, microscopy, and manipulation. However, conventional optical holography can address only the amplitude and phase information of an optical beam, leaving the 3D vectorial feature of light completely inaccessible.
