Electroosmotic Flow Modulation and Dispersion of Uncharged Solutes through a Reservoir-Connected Soft Nanochannel

Abstract The present study investigates the modulation of the electroosmotic flow (EOF) and the transport and dispersion of uncharged solutes in a reservoir-connected soft nanochannel containing different electrolytes. The nanochannel walls are charged and coated with a fluid- an...

An augmented ratingsystem for Test cricket: adapting the Glicko rating system

Abstract The International Cricket Council’s (ICC) rating system for Test cricket updates a team’s rating from match and series results alone. It makes no allowance for the precision of a rating, nor for contextual factors such as home advantage and the outcome of the toss. This...

On Fourier asymptotics and effective equidistribution

Abstract We prove effective equidistribution of expanding horocycles in the space SL 2 ⁢ ( Z ) \ SL 2 ⁢ ( R ) \mathrm{SL}_{2}(\mathbb{Z})\backslash\mathrm{SL}_{2}(\mathbb{R}) with respect to various classes of Borel probability measures on ℝ having certain Fourier asymptotics. Ou...

Correlated quasiperiodicity enables efficient thermoelectric energy conversion

We investigate a route to enhanced thermoelectric energy conversion in nanoscale systems by exploiting a correlated quasiperiodic energy landscape in a one-dimensional chain coupled to source and drain reservoirs. The considered modulation generates a highly non-uniform electroni...

Sacred Steinkerns: Shaligram Shilas as a Living Geomyth, and the Palaeontological Consequences of Devotional Custody

This paper looks at Shaligram shilas, the black spiral stones from Nepal's Kali Gandaki river that Hindus worship as forms of Vishnu, from two sides. As geology, they are Late Jurassic ammonoid fossils. The paper traces them from the Spiti Shale sea floor on the edge of the Tethy...

A unified testing approach for log-symmetry using Fourier methods

Continuous and strictly positive data that exhibit skewness and outliers frequently arise in many applied disciplines. Log-symmetric distributions provide a flexible framework for modeling such data. In this article, we develop new goodness-of-fit tests for log-symmetric distribu...

Measurement-Induced Local Dephasing Generates Symmetrically Located Entangled Sites in a Fermionic Tight-Binding Lattice

Abstract We investigate an odd-sized fermionic open tight-binding chain subjected to stochastic projective measurements at its central site, effectively inducing localized dephasing. Focusing initially on the single-particle regime, we demonstrate that when the system is prepared...

On the unit Teissier distribution: properties, estimation procedures and applications

The Teissier distribution, originally proposed by Teissier [31], was designed to model mortality due to aging in domestic animals. More recently, Krishna et al. [19] introduced the Unit Teissier (UT) distribution on the interval (0, 1) through the transformation $X=e^{-Y}$, where...

Synchronization of topological signals in higher-order adaptive multilayer network

The study of synchronization in complex systems has recently been revolutionized by incorporating higher-order interactions through simplicial complexes. Building in particular upon the higher-order Kuramoto model, which considers oscillators on nodes, links, and higher-dimension...

On two notions of torsion and metric compatibility of connections in noncommutative geometry

We compare the notions of metric compatibility and torsion of a connection in the frameworks of Beggs–Majid and Mesland–Rennie. It follows that for * -preserving connections, compatibility with a real metric in the sense of Beggs–Majid corresponds to Hermitian connections in the...

Scaling limit of a drainage network model on a perturbed lattice

Abstract The study of random networks generally requires that vertices be independently and uniformly distributed over disjoint regions such as a Poisson point process. In this work, we venture beyond this standard paradigm and investigate a stochastic forest obtained from a drai...

Change of the burden of infectious diseases and antimicrobial resistance in India: a systematic analysis for the Global Burden of Disease Study 2019 and 2021

Infectious diseases and antimicrobial resistance (AMR) remain one of the major causes of mortality and disability in India. But age- and pathogen-specific evidence on recent changes in AMR burden is limited. We analysed India-specific data from the Global Burden of Disease Antimi...

A review of major ionic species and trace elements in the Himalayan cryosphere

Snow and glacier deposits in the Himalayan cryosphere serve as important archives of atmospheric deposition. This review collates published data on major ions and trace elements in snow and ice from the Western, Central, and Eastern Himalayas and the Tibetan Plateau between 2000...

Playing with tokens (potentially infinite vertex capacity--Theoretical)

In this paper, a basic token sliding puzzle in graphs (with infinite vertex capacities) has been studied. The rule is in each step (or time epoch) we are moving k tokens simultaneously, where k may be fixed or may be varied over a given set T. The reachability characterisations i...

Two-person zero-sum games without expected utility preferences: a proposal

A solution concept for two-person zero-sum games is proposed with only the Independence axiom assumed of players' preferences. We do not assume Continuity which is critical for many fixed-point theorems. Each player is shown to admit a set of "admissible" strategies assuring mini...

A Review on Janus Nanoparticles: Duality Leading to Prospective Multipotent Applications

Janus nanoparticles (JNPs), named after the bi-faced Roman God has emerged as a hot topic in the present era of nanoscience because of their chemical, structural and physical uniqueness. These particles stand out in the crowd as they are composed of two or more faces with contras...

Learning models on rooted regular trees with majority update policy: Convergence and phase transition
