Methods to identify and distinguish the effects of weathering and landslides on sediment granulometry.

Urbanization has resulted in the widespread development of built-up areas, often without considering the local geology and geomorphology. To improve risk assessments related to landslides, it is essential to determine the physical and chemical properties of sediments. The aim of this study is to exemplify an already mobilized and reworked layer based on granulometric properties of the sediments and characterize the chemical and physical properties which have changed during or after the mass movement.

An automated neural network-based stage-specific malaria detection software using dimension reduction: The malaria microscopy classifier.

Due to climate change and the COVID-19 pandemic, the number of malaria cases and deaths, caused by the genus, of which is the most common and lethal to humans, increased between 2019 and 2020. Reversing this trend and eliminating malaria worldwide requires improvements in malaria diagnosis, in which artificial intelligence (AI) has recently been demonstrated to have a great potential. One of the main reasons for the use of neural networks (NNs) is the time saving through automatising the process and the elimination of human error.

Sudden death due to infiltration of left bundle branches by interventricular septal cardiac fibroma.

Cardiac fibromas are benign conditions; however, their location and size may cause ventricular arrhythmias and sudden cardiac death. We report a case of a 68-year-old female who died suddenly. Postmortem investigation detected a huge cardiac fibroma in the pars muscularis of the interventricular septum, occupying almost the entire muscular septum, and restricting the volume of left ventricular chamber.

Molecular organization in self-assembled binary porphyrin nanotubes revealed by resonance Raman spectroscopy.

Porphyrin nanotubes were formed by the ionic self-assembly of tetrakis(4-sulfonatophenyl) porphyrin diacid (H(4)TPPS(4)(2-)) and Sn(IV) tetra(4-pyridyl) porphyrin (Sn(OH(-))(X)TPyP(4+/5+) [X = OH(-) or H(2)O]) at pH 2.0. As reported previously, the tubes are hollow as revealed by transmission electron microscopy, approximately 60 nm in diameter, and can be up to several micrometres long.
