Statistical learning of materials properties or functions so far starts with a largely silent, nonchallenged step: the choice of the set of descriptive parameters (termed descriptor). However, when the scientific connection between the descriptor and the actuating mechanisms is unclear, the causality of the learned descriptor-property relation is uncertain. Thus, a trustful prediction of new promising materials, identification of anomalies, and scientific advancement are doubtful. We analyze this issue and define requirements for a suitable descriptor. For a classic example, the energy difference of zinc blende or wurtzite and rocksalt semiconductors, we demonstrate how a meaningful descriptor can be found systematically.

Memory is a dynamic process of encoding, storing, and retrieving information. It includes sensory, short-term, and long-term memory, each with unique characteristics. Nitric oxide (NO) is a biological messenger synthesized on demand by neuronal nitric oxide synthase (nNOS) through a biochemical process initiated by glutamate binding to NMDA receptors, causing membrane depolarization and calcium influx.

Volatile off-notes in ground pennycress seeds, ground defatted pennycress seed, and the final protein isolates (produced from the defatted seeds by alkaline or salt extraction) were identified and "quantified" relative to an internal standard. Volatiles contributing off-notes were identified based on mass spectra, retention indices, and aroma descriptors. The compounds that produced the strongest odors based on gas chromatography:olfactometry were identified as potential aroma impact compounds.

Background/objectives: Post-stroke hemiparetic gait often presents with asymmetric patterns to compensate for stability deficits. This study examines gait differences in chronic stroke patients with spastic hemiparesis based on initial foot contact type-forefoot versus rearfoot.
Methods: Thirty-four independently walking spastic hemiparetic patients were retrospectively analyzed.

In grid intelligent inspection systems, automatic registration of infrared and visible light images in power scenes is a crucial research technology. Since there are obvious differences in key attributes between visible and infrared images, direct alignment is often difficult to achieve the expected results. To overcome the high difficulty of aligning infrared and visible light images, an image alignment method is proposed in this paper.

Systemic arterial hypertension contributes to cardiovascular morbidity and mortality worldwide. Many patients cannot achieve optimal blood pressure (BP) control with traditional therapies, which often results in poor patient adherence and limited long-term efficacy. We investigated the potential of RNA interference (RNAi) therapies targeting hepatic angiotensinogen (AGT) for hypertension management.
