Quantum entanglement phase transitions have provided new insights into quantum many-body dynamics. Both disorders and measurements are found to induce similar transitions. Here, we provide a theoretical framework that unifies these two seemingly disparate concepts discloses their internal connections. Specifically, analytically analyze $d$-dimensional free-fermion gas subject continuous projective measurements. By mapping the Lindblad master equation functional Keldysh field theory, develop...
Background Recent studies have shown that systemic inflammation responses and hyperventilation are associated with poor outcomes in patients severe traumatic brain injury (TBI).

Reaching for and retrieving objects require precise coordinated motor movements in the forelimb. When mice are repeatedly trained to grasp retrieve food rewards positioned at a specific location, their performance (defined as accuracy speed) improves progressively over time, plateaus after persistent training. Once such reaching skill is mastered, its further maintenance does not constant practice. Here we introduce single-pellet task study acquisition of skilled forelimb mice. In this...

Bound states in the continuum (BICs) provide, what we believe to be, a novel and efficient way for light trapping. However, using BICs confine into three-dimensional compact volume remains challenging task, since energy leakage at lateral boundaries dominates cavity loss when its footprint shrinks considerably small, hence, sophisticated boundary designs turn out be inevitable. Conventional design methods fail solving problem because large number of degree-of-freedoms (DOFs) are involved....
