Owing to its non-invasive nature, echocardiography, is widely used in many fields of clinical sciences. Especially in cardiology, real-time pictures of the beating heart are now essential in clinical practice. With recent developments of computer technology, various aspects of computerization have been introduced into echocardiography. Analysis of cardiac function became easier by automated echocardiography with three dimensional framework, length-tension-velocity. A 3-dimensional view of the heart could also be obtained by computerized image processing of serial echocardiograms. The results of the automated analysis by computer were in good agreement with those with manual measurements. Therefore, the computer processing is valid. These kinds of computer image processing of echocardiograms would be useful in various clinical settings.

Electrochemiluminescence (ECL) combines electrochemical redox processes with photochemical light emission, offering exceptional sensitivity, spatial control, and stability. Widely applied in biosensing, medical diagnostics, and environmental monitoring, its efficiency often depends on advanced catalytic materials. Single-atom catalysts (SACs), featuring isolated metal atoms dispersed on a support, have emerged as promising candidates due to their unique electronic structures, high atom utilization, and tunable catalytic properties.

Identifying atomic-level mechanisms in elemental chemical reactions is crucial for understanding complex reaction processes. This study focuses on the typical multichannel H + NHCl reaction, which plays a significant role in environmental science. High-level ab initio calculations determined seven distinct reaction pathways, leading to three product channels: H + NHCl, HCl + NH, and Cl + NH.

Background: Hypochlorous acid (HClO) is a crucial disinfectant in the food industry. It can be used to soak perishable foods like vegetables, fruits, eggs, fish, and raw meat before processing and storage, eliminating microorganisms, bacteria, fungi, and pathogens to ensure food safety. HClO also helps preserve vegetables and fruits by reducing ethylene production, delaying rotting, decreasing cell membrane permeability, inhibiting polyphenol oxidase activity, and postponing discoloration.

Despite our subjective experience of a largely symmetric visual world, the human brain exhibits varying patterns and degrees of hemispheric asymmetry in distinct processes of visual cognition. This chapter reviews behavioral and neuroimaging evidence from neurotypical individuals and neurological patients, concerning functional asymmetries between the right hemisphere (RH) and the left hemisphere (LH) in visual object processing and mental imagery. Hierarchical perception shows RH preference for global processing and LH preference for local processing.

A defining characteristic of the human brain is that, notwithstanding the clear anatomic similarities, the two cerebral hemispheres have several different functional superiorities. The focus of this chapter is on the hemispheric asymmetry associated with the function of face identity processing, a finely tuned and expert behavior for almost all humans that is acquired incidentally from birth and continues to be refined through early adulthood. The first section lays out the well-accepted doctrine that face perception is a product of the right hemisphere, a finding based on longstanding behavioral data from healthy adult human observers.
