UBV photometric observations of Ap star Cyg V1584 have been presented. To find the rotational period of the star, a sinusoidal wave function has been fitted to the noramal points of UBV filters. Assuming that a circular hot spot located at the magnetic pole of the star is responsible for the observed light variations, both physical an geometrical parameters of the spot have been determined. F...
Background: Anti-angiogenic therapy is a crucial step in cancer treatment. The discovery of new anti-angiogenic compounds from marine organisms has become an attractive concept in anti-cancer therapy. Because little data correlated to the pro- and anti-angiogenic efficacies of Ophiuroidea, which include brittle star, the current study was designed to explore the anti-angiogenic potential of bri...
Evaluating lesion progression and treatment response via longitudinal tracking plays a critical role in clinical practice. Automated approaches for this task are motivated by prohibitive labor costs time consumption when matching is done manually. Previous methods typically lack the integration of local global information. In work, we propose transformer-based approach, termed Transformer Lesio...
In this paper, a robust visual tracking method is proposed to track an object in dynamic conditions that include motion blur, illumination changes, pose variations, and occlusions. To cope with these challenges, multiple trackers with different feature descriptors are utilized, and each of which shows different level of robustness to certain changes in an object’s appearance. To fuse these inde...
let g be a (p, q) graph. let k be an integer with 2 ≤ k ≤ p and f from v (g) to the set {1, 2, . . . , k} be a map. for each edge uv, assign the label |f(u) − f(v)|. the function f is called a k-difference cordial labeling of g if |νf (i) − vf (j)| ≤ 1 and |ef (0) − ef (1)| ≤ 1 where vf (x) denotes the number of vertices labelled with x (x ∈ {1, 2 . . . , k}), ef (1) and ef (0) respectively den...
