Recent experiments showed the possibility of creating long-lived, nonlinear kinetic structures in a pure-electron plasma. These structures, responsible for large-amplitude periodic density fluctuations, were induced by driving the plasma with a weak oscillating drive, whose frequency was adiabatically decreased in time fW.

We investigate new extensions of the Kruskal-Friedman theorems concerning well-quasiordering of finite trees with the gap condition. For two labelled trees s and t we say that s is embedded with gap into t if there is an injection from the vertices of s into t which maps each edge in s to a unique path in t with greater-or-equal labels. We show that finite trees are well-quasi-ordered with resp...

We investigate the massless scalar field perturbations of a new loop quantum gravity motivated regular black hole proposed by Ashtekar {\it et al.} in [Phys.Rev.Lett. 121, 241301 (2018), Phys.Rev.D 98, 126003 (2018)]. The spacetime this is distinguished its asymptotic properties: Schwarzschild coordinates one metric functions diverges as $r\to \infty$ even though asymptotically flat. show that ...

We perform the shadow calculation of loop quantum gravity motivated regular black hole recently proposed by Ashtekar, Olmedo and Singh (will be termed AOS hereafter). In process, we also construct rotating inspired solution originally static spherically symmetric applying modified Newman-Janis algorithm. study effects on shadows both non-rotating solutions. It is observed that general shape for...

Algoritma Kruskal dan Prim adalah dua algoritma pencarian Minimum Spanning Tree pada suatu graf yang mempunyai kemiripan. Seiring dengan perkembangan teknologi, muncul sebuah media pembelajaran baru yaitu game. Riset ini dilakukan untuk merancang menguji game dapat menjelaskan memvisualisasikan cara kerja Prim. Hasil riset diharapkan membuktikan bahwa efisiensi lebih dalam Data ada diambil dari...

Objective: To characterize the realized niche of Mexican spotted owl (Strix occidentalis lucida) and compare environmental values it uses within physiographic provinces.Design/methodology/approach: The temperature variables (n =7), precipitation = 7) elevation 1) were extracted from 79 unique occurrences sites S. o. lucida. These grouped by provinces: Sierra Madre Occidental 59), Oriental 13) T...

Human errors have serious role in the occurence of maritime accidents. More emphasis should be placed on human factor rather than automation and technology with quality effective training. In order to maintain safety culture board, it is necessary standardize effectiveness trainings.
 The aim this study determine training given seafarers seafarer candidates participating basic participants...

This study was carried out to find the burnout levels of judo coaches in COVID-19 period and show how they will approach their profession athletes after pandemic. 136 from different coaching participated study. Maslach Burnout Inventory used In addition, 3 qualitative questions were prepared by researchers emotions during pandemic approached athletes. IBM SPSS 22 statistical program analyze dat...

In the constructal design method, comprehension of effect on system performance is crucial to understanding contributions degrees freedom or constraints in evolution direction optimal configurations. However, problems with many are prohibitive optimization exhaustive search, requiring meta-heuristic strategies. Therefore, investigation algorithms essential. This work investigates canonical diff...
