As electronics advance toward higher performance and adaptability in extreme environments, traditional metal-oxide-semiconductor field-effect transistors (MOSFETs) face challenges due to physical constraints such as Boltzmann's law and short-channel effects. Nanoscale air channel transistors (NACTs) present a promising alternative, leveraging their vacuum-like channel and Fowler-Nordheim tunneling characteristics. In this study, a novel circular gate NACT (CG-NACT) is purposed, fabricated on a 4-inch silicon-based wafer using a CMOS-compatible process.
View Article and Find Full Text PDFTwo key series of discoveries about the hippocampus are described. One is the discovery of hippocampal spatial view cells in primates. This discovery opens the way to a much better understanding of human episodic memory, for episodic memory prototypically involves a memory of where people or objects or rewards have been seen in locations "out there" which could never be implemented by the place cells that encode the location of a rat or mouse.

The name Aspistomella Hendel, 1909 is a new senior subjective synonym of Paraphyola Hendel, 1909. The group of genera is extended by the addition of six known species, Aspistomella angustifrons (Hendel, 1909) comb.

The traditional technique for mental never reconstruction after segmental mandibulectomy is to bridge the gap between the proximal end of the inferior alveolar nerve (IAN) and the mental nerve stump. However, it often presents significant challenges. In cases of proximal IAN stump is close to skull base or kept inside the remaining mandible body and ramus, approaching the proximal end of the IAN can be very challenging.

Tunnels in the Western Plateau region of China often face numerous problems of high ground stress, as well as highly fractured and weak rock masses in deep sections of the tunnel, which results in an increased risk of large soft rock deformation in tunnels, posing substantial challenges to safe and efficient construction. Hence, risk assessment and establishment of an early safety warning system are essential. By examining factors affecting the large soft rock deformation in tunnels, a set of index system consisting of three primary indicators (i.
