Adaptive guidance and control for future remote sensing systems [PDF]

, 1980
A unique approach to onboard processing was developed that is capable of acquiring high quality image data for users in near real time. The approach is divided into two steps: the development of an onboard cloud detection system; and the development of a

Skeletal Muscle HSF1 Alleviates Age‐Associated Sarcopenia and Mitochondrial Function Decline via SIRT3‐PGC1α Axis

Advanced Science, EarlyView.
Aged HSF1 muscle‐specific knockout mice show deteriorated muscle atrophy and metabolic dysfunction, while active HSF1 overexpression improves muscle function via activating SIRT3 to deacetylate both PGC1α1 and PGC1α4, which boosts mitochondrial function and muscle hypertrophy in a fiber‐type specific manner, and induces FNDC5/Irisin for tissue ...

Versatile CRISPR‐Cas Tools for Gene Regulation in Zebrafish via an Enhanced Q Binary System

Advanced Science, EarlyView.
This study introduces CRISPR‐Q, a transgenic CRISPR‐Cas system leveraging the QFvpr/QUAS binary expression platform in zebrafish. CRISPR‐Q overcomes previous challenges in achieving stable and efficient gene regulation. By enabling precise spatiotemporal control of transcript knockdown (CRISPR‐QKD) and gene activation (CRISPR‐Qa), it provides a ...

Variable structure wireless power transfer converter with misalignment tolerant

International Journal of Electrical Power & Energy Systems
Misalignment of the secondary coil relative to the primary coil is inevitable in the wireless power transfer (WPT) converter, which decreases the transmission power and the system efficiency. Moreover, constant current (CC) and constant voltage (CV) control methods should be used to improve the charging efficiency of the battery.

DNA Nanostructure‐Templated Multivalency Enables Broad‐Spectrum Virus Inhibition

Advanced Science, EarlyView.
A honeycomb‐shaped DNA nanostructure is introduced that organizes nanobodies or aptamers into trimeric clusters mirroring the native hemagglutinin arrangement on influenza viruses. This geometry‐matched multivalency enhances binding avidity by up to 1000‐fold, resulting in robust, broad‐spectrum viral neutralization and a 30–55% improvement in host ...

The dynamic characteristics of a turbo-rotor simulator supported on gas-lubricated foil bearings. Part 2: Operation with heating and thermal gradients [PDF]

A high speed rotor, supported by gas-lubricated foil bearings, is free from self-excited whirl and displays no loss of load capacity when vibrated at frequency equal to the rotational speed. It is demonstrated that in addition to tolerance of geometrical
