There has been little recent work on the relationship between the behaviour of gastropod molluscs and the activity of their nervous systems. Older workers (e.g. ten Cate, 1928), studied the effects of electrical stimulation of different nerves on the movements of parts of the animal. More recently observations on the spontaneous activity and electrical properties of individual cells in isolated...

We present PLTplot, a plotting package for PLT Scheme. PLTplot provides a basic interface for producing common types of plots such as line and vector field plots from Scheme functions and data, an advanced interface for producing customized plot types, and support for standard curve fitting. It incorporates renderer constructors, transformers from data to its graphical representation, as values...

Optical spectroscopy techniques, including visible and near infrared (IR) Raman and synchrotron IR methods have been applied to study solid nitrogen at megabar pressures. We find that nitrogen becomes totally opaque above 150 GPa, accompanied by the disappearance of Raman and IR vibrational excitations, while new broad IR and Raman bands become visible. Optical absorption measurements reveal th...

Processes of holographic recording of surface relief structures using As2S3:Mn-Se multilayer nanostructures as registering media were studied in this paper. Optical properties of As2S3:Mn, Se layers, and As2S3:Mn-Se multilayer nanostructures were investigated. Values of optical bandgaps were obtained from Tauc dependencies. Surface relief diffraction gratings were recorded. Direct one-stage for...

Abstract PURPOSE/OBJECTIVE(S) The primary purpose of this study is to determine whether a machine learning approach can estimate survival in patients with brain metastases undergoing stereotactic radiosurgery or fractionated radiotherapy (SRS/SRT). secondary identify covariates importance. MATERIALS/METHODS Data were collected for 377 SRS/SRT treatments 291 done between the years 2008-2021. If ...

The photocatalytic process over semiconducting oxide surfaces has attracted worldwide attention as a potentially efficient, environmentally friendly, and low-cost method for wastewater treatment. This study presents straightforward, inexpensive, rapid route the synthesis of nickel (NiO) its composites with zinc (NiO/ZnO) copper (NiO/CuO) nanoparticles through chemical precipitation using cappin...

A green and easy technique was used to synthesize silver silica (Ag@SiO2) core–shell nanoparticles (NPs) in the matrix blend polymers matrix. Core–shell were loaded into polyvinyl alcohol (PVA) ultrahigh molecular weight polyethylene oxide (UHMW-PEO) blended polymer fabricate new nanocomposite films (NCFs) using developed solution-sonication-casting technique. The spectroscopic properties of re...
