Hace 1 día · Dynamical interactions in globular clusters (GCs) significantly impact the formation and evolution of binary sources, including cataclysmic variables (CVs). This study investigates the connection between dynamical states of GCs and X-ray luminosity ( L x ) distributions of CV populations through both simulations and actual observations.

Hace 5 días · In this area, students are introduced to the study of human communication as a process. Emphasis is on examining the role of self-concept, perception, culture, verbal and nonverbal dimensions in the communication process; applying critical listening skills; and developing skills in oral presentations.
Hace 6 días · Clustering. KMeans : on doit préciser le nombre de clusters. L'algorithme cherche K centroïdes qui vont minimiser l'inertie, en faisant l'hypothèse que les clusters sont convexes et isotropes. kmeans.transform (X2) : donne pour chaque individus les distances par rapport aux différents centroïdes (matrice nombre d'individus x nombre de ...
Hace 2 días · Highly active and robust Pt-based electrocatalysts for an oxygen reduction reaction (ORR) are of crucial significance for the development of proton exchange membrane fuel cells (PEMFCs). Herein, the high-loading and well-dispersive Pt clusters on graphitic carbon-supported CeO2 with abundant oxygen vacancies (PtAC/CeO2-OV@GC) were successfully fabricated by a molten-salt electrochemical ...
Hace 2 días · Gas-phase metal clusters are ideal models to explore transition-metal-mediated N 2 activation mechanism. However, the effective design and search of reactive clusters in N 2 activation are currently hindered by the lack of clear guidelines. Inspired by the Sabatier principle, we discovered in this work that N 2 initial adsorption energy (ΔE ads) is an important parameter to control the N 2 ...
