Vidyasagar College (Bengali: বিদ্যাসাগর কলেজ) is a state government-aided public college, affiliated to the University of Calcutta, located in North Kolkata, West Bengal, India. The college offers both post-graduate and under-graduate courses in a number of subjects of arts and science. Founded in 1872, it was the first private college (now governmental) in India which was purely run, maintained and financed by Indians. Formerly known as Metropolitan Institution, it was named after its founder Pandit Ishwar Chandra Vidyasagar in 1917.The college is affiliated to Calcutta University, under UGC and accredited by NAAC. It follows semester based CBCS system. The college does not participate in NIRF ranking in college category. The college was a part of DBT STAR College Scheme. The college receives funding from State Government, UGC (via CU) and other GOI-affiliated institutes or schemes i.e RUSA, ICSSR, AICTE and NIEIT.
Cupric oxide (CuO) is a key p-type semiconductor in advancing third-generation solar cells. This study analyzes four heterojunction solar cells: CuO/Si, CuO/ZnO, CuO/SnO2, and CuO/CdS, using SCAPS simulations. Platinum (Pt) serves as the metal contact and indium tin oxide (ITO) is the substrate layer, offering higher efficiency than traditional Si substrates. The power conversion efficiency (PCE) of the Pt/CuO/CdS/ITO cell reaches an impressive 26.59
We study the fate of a forager who searches for food performing a random walk on lattices. The forager consumes the available food on the site it visits and leaves it depleted but can survive up to S steps without food. We introduce the concept of intermittent rest in the dynamics which allows the forager to rest with probability p upon consumption of food. The parameter p significantly affects the lifetime of the forager, showing that the intermittent rest can be beneficial for the forager for chosen parameter values. The study of various other quantities reveals interesting scaling behavior with p and also departure from usual diffusive behavior for 0.5 < p < 1. In addition to numerical simulations, the problem has been studied with analytical approach in one dimension and the results up to p < 0.5 agree with the numerical ones to a large extent.
The low-temperature metallic phase of 1T-TaS2 may originate from the current-and voltage-driven destabilization of the commensurate charge density wave in a strongly correlated Mott-insulator, alongside the robust yet rarely realized influence of intrinsic electronic distortions. Electrical pulse-driven transport, combined with the second harmonic response, reveals abrupt switching, negative differential resistance, and multiscale domain-wall reorganization. The free-energy analysis identifies a critical order parameter threshold for the Mott-metal transition, with scaling exponents (beta 1.3) consistent with two-dimensional percolation. The sparse limit fractal dimension Df 0.3 at 10 K, rising to 0.9 at 300 K, reflects the hierarchical evolution of the conductive pathways throughout the temperature. These findings establish a direct connection between fractal percolation, pulse-induced instabilities, and correlated electron transport, offering a framework for controlled access to nonequilibrium phase transitions in low-dimensional quantum materials.
Moral Philosophy or ethics is that branch of philosophy which investigates the nature of good and bad, right and wrong, and how human beings ought to live. Each moral theory provides certain moral standard and principle in order to ascertain the moral worth of an individual’s action. One such ethical theory is that of 18th century moralist David Hume. David Hume is an eminent Scottish philosopher in the history of Western Philosophy, known for his empiricist theory of knowledge and philosophical scepticism. But he has also made important contribution to moral philosophy. Hume’s moral philosophy is primarily found in Book 3 of The Treatise of Human Nature and his Enquiry Concerning the Principles of Morals. Hume’s moral theory was mostly influenced by the Scottish thinkers, such as - Francis Hutcheson and Third Earl of Shaftesbury; who have also emphasised the role of emotion in morality. He rejects the rationalist conception of morality which claims that through reason alone, human beings make moral evaluations and understand right and wrong. While influenced by his predecessors, Hume developed his moral theory which is primarily rooted in moral sentimentalism. He contends that morality is primarily based on ‘sentiments’ or ‘feelings’ rather than on universal reason. This is so because, for him, human beings in addition to our faculty of reason, have the requisite emotional capacities, which help us to determine that some action is ethically right or wrong, or a person has a virtuous moral character. This view of Hume is in contrast with Immanuel Kant’s moral philosophy, who bases morality on reason and universal duty. Thus, Hume’s ethical thought basically deals with the questions about the role of sentiments in thought, action and morality, intimate relationship between human sentiments and morality and the nature of moral evaluation. The object of this paper is to give a short account of Hume’s moral theory by analysing Hume’s sentimentalism and the instrumental role of reason, and the consequences of his moral theory. In conclusion it seems to us that in spite of some objections raised against his moral theory, yet Hume’s moral theory has its own relevance.
Purpose The primary objective of this article is to study weakly cyclic contracted space-matter tensor under the influence of semi-symmetric metric connection through computational procedure. An important observation regarding spacetime anomalies is obtained in this article. Design/methodology/approach Applying the Frobenius method, non-linear differential equation has been solved through numerical simulation. Findings The study presents the following findings: (1) The observation signifies the existence of high-level energy (or black hole) in the era of cosmological theory. The SSMC developed here can be taken into account, which is the futuristic scope of the present study, for various cosmological models to examine in the context of different energy conditions. (2) Spacetime anomalies are shifted towards the increasing direction of x1. Originality/value The study has been developed newly with the help of a new approach involving numerical simulation.
