Refined curve counting with tropical geometry

The Severi degree is the degree of the Severi variety parametrizing plane curves of degree $d$ with ${\it\delta}$ nodes. Recently, Göttsche and Shende gave two refinements of Severi degrees,

An improved lower bound for the conductivity of three-component composite materials is determined using a new quantitative rigidity estimate for gradient fields in two dimensions.

Analysis on Tweets Towards COVID-19 Pandemic: An Application of Text-Based Depression Detection

It is shown that depression level got doubled from four percent to eight percent from the beginning to the end of March 2020 and increased after nearly two years to reach 15 percent in December 2021.

On Phase Transitions near Black Holes

It has been shown that temperatures near the horizon of rotating black holes can be about the phase transition temperature in the Standard Model with the Higgs boson. The distance from the horizon

A new variational formulation and a method for solving the problem of quasi-geostrophic dynamics in a two-layer periodic channel are considered. The area imitates the zone of the Antarctic

Performance of an Asymmetric on–Off Keying Modulation for Space Communications Using Single-Photon Superconducting Nanowire Detectors

Communications from deep space need to overcome two major issues: the strong attenuation due to the large distances and the limited power available at the transmitter. A class of sensors which looks

Evaluation of Medical Image Segmentation Models for Uncertain, Small or Empty Reference Annotations

This work examines publicly available metrics on the predictions of a deep learning framework in order to identify for which settings common metrics provide clinical meaningful results.

Pemodelan Indeks Pembangunan Manusia di Indonesia dengan Geographically Weighted Regression (GWR)

The Human Development Index (HDI) is an important indicator to measure success in efforts to build the quality of human life. The HDI explains how the population can access development outcomes in
