Abstract:
This study considers the mathematical analysis framework aimed at the adequate description of the modes of lasers on the threshold of non-attenuated in time light emission. The lasers are viewed as open dielectric resonators equipped with active regions, filled in with gain material. We introduce a generalized complex-frequency eigenvalue problem for such cavities and prove important properties of the spectrum of its eigensolutions. This involves reduction of the problem to the set of the Muller boundary integral equations and their discretization with the Nystrom technique. Embedded into this

Aim: Major sickle cell sufferers residing in tropical regions find themselves at the crossroads of several situations that can modify their iron status. Our aim was to describe ferritin levels in sickle cell patients at Centre National de Recherches et de Soins aux Drépanocytaires (CNRSD) of Lomé. Methods: This was a cross-sectional study of sickle cell patients seen in medical consultations from May 16 to July 15, 2022. We included all sickle cell patients with anemia, who were seen in a medical monitoring during the study period and who gave their free consent. MINDRAY automatic system BC 60

Abstract:
Star anise (Illicium verum) has been cultivated for centuries in southern China, and its fruit is an important seasoning spice, and can be used as a medicine (Wang et al. 2011). It is grown mainly in Guangxi, Guangdong, Guizhou, and Yunnan provinces, in China. Anthracnose is one of the important diseases of star anise, which seriously affects the yield and quality by infecting twigs, pedicels, fruit stalks and fruits (Liao et al. 2017). When leaf spots first appear, they are round, water-stained, small, dark brown spots, which expands into round separated spots, then the spots become yellowish

Abstract:
Introduction Since at least the work of van Gennep in the early 1900s, anthropologists have recognised that borders and thresholds are crucial in understanding human behavior and culture. But particularly in the past few decades, the study of borders has moved from the margins of social inquiry to the centre. At the same time, fashion (Entwistle), including clothing and skin (Bille), have emerged as crucial to understanding the human condition. In this article, we draw on and expand this literature on borders and fashion to demonstrate that the way Indonesians fashion and display their body re

Abstract:
We study a host of geometric optimization problems that are NP-hard and design polynomial time approximation algorithms for them. More precisely, we are given a family of geometric objects and a point set, mostly in the plane, and study different variants and generalizations of Packing and Covering problems. Our objects of study are mostly family of non-piercing regions in the plane. We call a set of simple and connected regions to be non-piercing if for any pair of intersecting regions, A and B both A\B and B\A are connected regions. A set of disks, squares, half-planes are examples of non-pi

Abstract:
Abstract Self-piercing rivet (SPR), a method used for joining sheet materials, is of increasing interest in the automobile industry. Cracks on the SPR joint surface might affect the joint strength significantly. This paper proposed a novel crack detection and evaluation method for SPR button images based on machine learning, which will address the issue of time-consuming and subjective caused by manual visual crack inspection. Firstly, sub-images are cropped from the button images and preprocessed into three categories (i.e., cracks, edges, and smooth regions) as training samples. At the sub-i

It is both a pleasure and privilege to present a paper on the uniqueness of linearised water waves at this mini-symposium in honour of Professor John Wehausen whose classic review article Surface Waves (with E. V. Laitone) has done so much to influence workers in the field in the forty-two years since its publication. The question of the uniqueness of solutions to the linearised water wave equations was settled once and for all in a paper in the Journal of Fluid Mechanics by M. McIver (1996). She constructed a solution for the motion between a pair of fixed rigid surface-piercing cylinders in
