Regiospecific Methylalumination of Silacyclopropenes: The Access to Z-1-Silyl-2-Aluminyl-Disubstituted Olefins.

A methodology to access Z-1-silyl-2-aluminyl-disubstituted olefins is developed. It relies on the uncatalyzed ring opening of silacyclopropenes in the presence of a stoichiometric amount of trimethylaluminum. The resulting heterosubstituted alkenes exhibit a particular interaction between the electron-rich [Si-CH] moiety and the electron-deficient diorganoaluminyl group, resulting in similar geometrical features due to the proximity of these two centers.

Previous studies have shown an increased relative abundance of this bacterium associated with oral dysplasia or within oral tumours. Using direct culture, we found that 75 % of species isolated from malignant or potentially malignant oral mucosa were subsp.

Stunting and Underweight among Adolescent Girls of Indigenous Communities in Telangana, India: A Cross-Sectional Study.

India's indigenous groups remain vulnerable to malnutrition, despite economic progress, reflecting the reliance on traditional agriculture and the problems of poverty and inadequate education and sanitation. This mixed-methods study analyzed the incidence, causes and determinants of chronic malnutrition, measured through stunting, thinness and underweight among adolescent indigenous girls in Telangana. Using 2017 data on 695 girls aged 11-18 years from 2542 households, the analysis showed that 13% had normal nutritional status, while 87% were stunted, underweight or thin.

Multi-Class Seizure Type Classification Using Features Extracted from the EEG.

In this study, we classify the seizure types using feature extraction and machine learning algorithms. Initially, we pre-processed the electroencephalogram (EEG) of focal non-specific seizure (FNSZ), generalized seizure (GNSZ), tonic-clonic seizure (TCSZ), complex partial seizure (CPSZ) and absence seizure (ABSZ). Further, 21 features from time (9) and frequency (12) domain were computed from the EEG signals of different seizure types.

Mechanochemical Pretreated MAX (MAX) Phase to Synthesize 2D-TiCT MXene Sheets for High-Performance Supercapacitors.

Two-dimensional (2D) MXenes sheet-like micro-structures have attracted attention as an effective electrochemical energy storage material due to their efficient electrolyte/cation interfacial charge transports inside the 2D sheets which results in ultrahigh rate capability and high volumetric capacitance. In this article, TiCT MXene is prepared by a combination of ball milling and chemical etching from TiAlC powder. The effects of ball milling and etching duration on the physiochemical properties are also explored, as well as the electrochemical performance of as-prepared TiC MXene.

CTSC-Net: an effectual CT slice classification network to categorize organ and non-organ slices from a 3-D CT image.

Computed tomography (CT) is a non-invasive diagnostic imaging modality that reveals more insight into human organs than conventional X-rays. In general, the CT output is a 3-D image that is formed by combining multiple 2D images or slices together. It is essential to keep in mind that not all of the slices provide significant information to detect tumours.
