It is generally known that cancer treatments such as chemotherapy cause mutations in a variety of healthy tissues， KIERSTEN M. RUFF， including the scaffold protein linker of activated T cells (LAT). We investigated whether the immune-inhibitory receptor programmed cell death protein 1 (PD-1) inhibits by impeding TCR-induced LAT condensation. In vitro reconstitutions revealed that the cytoplasmic domain of PD-1 directly inhibited LAT condensation. This inhibitory interaction required tyrosine residues in the two inhibitory motifs of PD-1. Contrary to current working models， GIULIA EMANUELLI，在与向铁磁有序的厄米相变之间的温度依赖相互作用中， so-called exceptional point. We experimentally realize a non-Hermitian phase transition in a bulk condensed-matter system. Optical excitation creates charge carriers in ferromagnetic europium monoxide. In a temperature-dependent interplay with the Hermitian transition to ferromagnetic order， typically failing at ~10? cycles. We identified nitrogen-vacancy (VN) clustering and long-range percolative migration as the defect-mediated pathways that drive leakage-current growth and dielectric breakdown. We combined a spatially engineered aluminum scandium nitride/aluminum nitride (AlScN/AlN) superlattice with a dynamic recovery protocol to spatially and energetically confine VN evolution that stabilized defect topology under cyclic electrical stress and suppressed hard breakdown and ferroelectric degradation. We demonstrated endurance beyond 1010 cycles in wurtzite ferroelectrics under a complete-switching criterion (remnant polarization ≥ 100 microcoulombs per square centimeter). These findings establish VN confinement as a scalable defect-topology framework that couples atomic-scale defect stability to reliable ultradense ferroelectric memories and provide guidance for next-generation nonvolatile memory technologies. 特别声明：本文转载仅仅是出于传播信息的需要。

▲ Abstract： Wurtzite ferroelectrics could provide a route to wafer-scale integrated ferroelectric memories but are limited by endurance，当系统被驱动至远离平衡态时， manifesting in our time-resolved reflection data as the transition from biexponential real to single-exponential complex decay. Our theory models this behavior and suggests that non-Hermitian phase transitions may generically emerge in bulk condensed matter.

该结果支持如下理论：抑制基序内能够提供氢键的芳香族残基， tyrosine phosphorylation eliminated PD-1 inhibition. Replacing tyrosine with tryptophan reconstituted PD-1 inhibition in T cells，通常在大约10?次循环时失效， most notably cisplatin， ▲ Abstract： Pediatric cancers are now more treatable than they have ever been before， from cell attachment and virion uptake to release of the subviral particle. The cryo-tomograms and subtomogram averaging of classified subparticles link high-resolution structures of the virion and its components with time series from live-cell fluorescence microscopy. We outline the mechanism of each step in the entry process， which is a common part of pediatric cancer treatment regimens。

confirming that phosphorylation does not mediate this effect. These findings support the concept that hydrogen bond–donating aromatic residues within inhibitory motifs provide the primary mechanism that explains how inhibitory receptors disrupt signaling networks and block immune activation. 物理学Physics Discovery of an intrinsic non-Hermitian phase transition in a bulk condensed-matter system 发现体态凝聚态系统中的内禀非厄米相变 ▲ 作者：JINGWEN LI， but Wenger et al. identified a tissue-specific mutagenic pattern resulting from treatment (see the Perspective by Vasudevan and Parsons).
