Unlikely intersections on the -adic formal ball.

We investigate generalizations along the lines of the Mordell-Lang conjecture of the author's -adic formal Manin-Mumford results for -dimensional -divisible formal groups . In particular, given a finitely generated subgroup of and a closed subscheme , we show under suitable assumptions that for any points satisfying for some , the minimal such orders are uniformly bounded whenever does not contain a formal subgroup translate of positive dimension. In contrast, we then provide counter-examples to a full -adic formal Mordell-Lang result.

Fabrication of Flexible Supercapacitor Electrode Materials by Chemical Oxidation of Iron-Based Amorphous Ribbons.

A flexible electrode constructed from Fe-based amorphous ribbons decorated with nanostructured iron oxides, representing the novelty of this research, was successfully achieved in one-step via a chemical oxidation method, using a low concentration of NaOH solution. The growth of metal oxides on a conductive substrate, which forms some metal/oxide structure, has been demonstrated to be an efficient method for increasing the charge transfer efficiency. Through the control and variation of synthetic parameters, different structures and morphologies of iron oxide were obtained, including hexagonal structures with a hollow ball shape and rhombohedral structures with rhombus-like shapes.

Self-Powered Photodetector Based on FTO/-TiO/-CuMnO Transparent Thin Films.

A self-powered photodetector with the FTO/-TiO/-CuMnO configuration, representing the novelty of the work, was successfully achieved for the first time and presumes two steps: deposition of the -type semiconductor (TiO) by the doctor blade method and of the -type semiconductor (CuMnO) by the spin coating technique, respectively. Investigation techniques of the structural and morphological characteristics of the as-synthesized heterostructures, such as XRD, UV-VIS analysis, and SEM/EDX and AFM morphologies, were used. The measurements of the photodetector showed that the responsivity in the self-powered mode was 2.

Sliding Wear Behavior of High-Temperature Vacuum-Brazed WC-Co-NiP Functional Composite Coatings.

The present study aimed to investigate the tribological behavior of high-temperature vacuum-brazed WC-Co-NiP functional coatings deposited on 16MnCr5 case hardening steel. Dry sliding wear resistance was evaluated using a non-conformal ball-on-disk arrangement, at room temperature against 100Cr6 and WC-Co static partners, respectively. Morphological, microstructural, and chemical composition analyses showed a complex, phased structure composed of tungsten carbide, nickel, and hard cobalt-based η-structure.

Increased Incidence of Type 1 Diabetes during the COVID-19 Pandemic in Romanian Children.

: It is known that several viruses are involved in the pathogenesis of type 1 diabetes. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a new worldwide spread virus that may act as a trigger for the autoimmune destruction of the β-cells, as well, and thus lead to an increase in the incidence of type 1 diabetes. The Romanian National Organization for the Protection of Children and Adolescents with Diabetes (ONROCAD) has collected information regarding new cases of type 1 diabetes in children aged 0 to 14 years from all over the country since 1996 and has computed the incidence of type 1 diabetes in this age group.
