Random-Receiver Quantum Communication
Some Sankar Bhattacharya, Ananda G. Maity, Tamal Guha +2
We introduce the task of random-receiver quantum communication, in which a sender transmits a quantum message to a receiver chosen from a list of n spatially separated parties. The…
On parabolic convergence of positive solutions of the heat equation
Jayanta Sarkar
In this article, we study certain type of boundary behaviour of positive solutions of the heat equation on the upper half-space of . We prove that the existence of the pa…
On Pointwise converse of Fatou's theorem for Euclidean and Real hyperbolic spaces
Jayanta Sarkar
In this article, we extend a result of L. Loomis and W. Rudin, regarding boundary behavior of positive harmonic functions on the upper half space . We show that similar…
The Nisnevich Motive of an Algebraic Stack
Utsav Choudhury, Neeraj Deshmukh, Amit Hogadi
We construct the motive of an algebraic stack in the Nisnevich topology. For stacks which are Nisnevich locally quotient stacks, we give a presentation of the motive in terms of si…
Vortex Flows and Streamline Topology in Curved Biological Membranes
Rickmoy Samanta, Naomi Oppenheimer
When considering flows in biological membranes, they are usually treated as flat, though more often than not, they are curved surfaces, even extremely curved, as in the case of the…
Automated Clustering of High-dimensional Data with a Feature Weighted Mean Shift Algorithm
Saptarshi Chakraborty, Debolina Paul, Swagatam Das
Mean shift is a simple interactive procedure that gradually shifts data points towards the mode which denotes the highest density of data points in the region. Mean shift algorithm…
Asymptotically Improved Circuit for -ary Grover's Algorithm with Advanced Decomposition of -qudit Toffoli Gate
Amit Saha, Ritajit Majumdar, Debasri Saha +2
The progress in building quantum computers to execute quantum algorithms has recently been remarkable. Grover's search algorithm in a binary quantum system provides considerable sp…
High dimensional PCA: a new model selection criterion
Abhinav Chakraborty, Soumendu Sundar Mukherjee, Arijit Chakrabarti
Given a random sample from a multivariate population, estimating the number of large eigenvalues of the population covariance matrix is an important problem in Statistics with wide…
On members of Lucas sequences which are either products of factorials or product of middle binomial coefficients and Catalan numbers
Shanta Laishram
Let be a Lucas sequence. Then the equation with implies . Further…
Multi-copy adaptive local discrimination: Strongest possible two-qubit nonlocal bases
Manik Banik, Tamal Guha, Mir Alimuddin +3
Ensembles of composite quantum states can exhibit nonlocal behaviour in the sense that their optimal discrimination may require global operations. Such an ensemble containing N pai…
A drainage network with dependence and the Brownian web
Azadeh Parvaneh, Afshin Parvardeh, Rahul Roy
We study a system of coalescing random walks on the integer lattice in which the walk is oriented in the -th direction and follows certain specified rules. We f…
The Human Cell Atlas & Equity: Lessons Learned
Partha P. Majumder, Musa M. Mhlanga, Alex K. Shalek
The Human Cell Atlas has been undergoing a massive effort to support global scientific equity. The co-leaders of its Equity Working Group share some lessons learned in the process.
Exploration about the origin of galactic and extragalactic star clusters through simulated H-R diagrams
Tanuka Chattopadhyay, Sreerup Mondal, Suman Paul +2
The present work explores the origin of the formation of star clusters in our Galaxy and in Small Magellanic Cloud (SMC) through simulated H-R diagrams and compare those with obser…
Infection spreading and recovery in a square lattice
Suman Saha, Arindam Mishra, Syamal K. Dana +2
We investigate spreading and recovery of disease in a square lattice, and in particular, emphasize the role of the initial distribution of infected patches in the network, on the p…
Optimal test-kit based intervention strategy of epidemic spreading in heterogeneous complex networks
Subrata Ghosh, Abhishek Senapati, Joydev Chattopadhyay +2
We propose a deterministic compartmental model of infectious disease which considers the test-kits as an important ingredient for the suppression and mitigation of epidemics. A rig…
Quantum Cycle in Relativistic Non-Commutative Space with Generalized Uncertainty Principle correction
Pritam Chattopadhyay, Tanmoy Pandit, Ayan Mitra +1
Quantum heat cycles and quantum refrigerators are analyzed using various quantum systems as their working mediums. For example, to evaluate the efficiency and the work done of the…
Robust Estimation under Linear Mixed Models: The Minimum Density Power Divergence Approach
Giovanni Saraceno, Abhik Ghosh, Ayanendranath Basu +1
Many real-life data sets can be analyzed using Linear Mixed Models (LMMs). Since these are ordinarily based on normality assumptions, under small deviations from the model the infe…
Time dependent fluctuations of linear eigenvalue statistics of some patterned matrices
Arup Bose, Shambhu Nath Maurya, Koushik Saha
Consider the reverse circulant and symmetric circulant matrices with independent Brownian motion entries. We discuss the process convergence of the…
The Unit-Gompertz Distribution: Characterizations and Properties
M Z Anis
In a recent paper, Mazucheli et al. (2019) introduced the unit-Gompertz (UG) distribution and studied some of its properties. In a complementary work, Anis and De (2020) corrected…
The Ising universality class of kinetic exchange models of opinion dynamics
Sudip Mukherjee, Soumyajyoti Biswas, Arnab Chatterjee +1
We show using scaling arguments and Monte Carlo simulations that a class of binary interacting models of opinion evolution belong to the Ising universality class in presence of an…
Pareto efficient combinatorial auctions: dichotomous preferences without quasilinearity
Komal Malik, Debasis Mishra
We consider a combinatorial auction model where preferences of agents over bundles of objects and payments need not be quasilinear. However, we restrict the preferences of agents t…
Reliable, Fair and Decentralized Marketplace for Content Sharing Using Blockchain
Prabal Banerjee, Chander Govindarajan, Praveen Jayachandran +1
Content sharing platforms such as Youtube and Vimeo have promoted pay per view models for artists to monetize their content. Yet, artists remain at the mercy of centralized platfor…
CODO: An Ontology for Collection and Analysis of Covid-19 Data
B. Dutta, M. DeBellis
The COviD-19 Ontology for cases and patient information (CODO) provides a model for the collection and analysis of data about the COVID-19 pandemic. The ontology provides a standar…
Ordinal Bayesian incentive compatibility in random assignment model
Sulagna Dasgupta, Debasis Mishra
We explore the consequences of weakening the notion of incentive compatibility from strategy-proofness to ordinal Bayesian incentive compatibility (OBIC) in the random assignment m…
