Phase modulated domain walls and dark solitons for surface gravity waves
Harneet Kaur, Shailza Pathania, Amit Goyal +2
We report theoretical prediction of exact localized solutions for dynamics of surface gravity waves, at the critical point kh=1.363, modelled by higher-order nonlinear Schrodinger…
Controlled self-similar matter waves in PT-symmetric waveguide
Shailza Pathania, Harneet Kaur, Amit Goyal +1
We study the dynamics of Bose-Einstein condensate coupled to a waveguide with parity-time symmetric potential in the presence of quadratic-cubic nonlinearity modelled by Gross-Pita…
Viral Marketing Meets Social Advertising: Ad Allocation with Minimum Regret
Cigdem Aslay, Wei Lu, Francesco Bonchi +2
In this paper, we study the problem of allocating ads to users through the viral-marketing lens. Advertisers approach the host with a budget in return for the marketing campaign se…
Comments on "Fundamental nature of the self-field critical current in superconductors", arxiv:2409.16758
Amit Goyal, Rohit Kumar, Armando Galluzzi +1
We provide comments on article "Fundamental nature of the self-field critical current in superconductors" by Talantsev and Tallon, arXiv:2409.16758 and https://papers.ssrn.com/sol3…
Deeply Supervised Semantic Model for Click-Through Rate Prediction in Sponsored Search
Jelena Gligorijevic, Djordje Gligorijevic, Ivan Stojkovic +3
In sponsored search it is critical to match ads that are relevant to a query and to accurately predict their likelihood of being clicked. Commercial search engines typically use ma…
Physics-based reward driven image analysis in microscopy
Kamyar Barakati, Hui Yuan, Amit Goyal +1
The rise of electron microscopy has expanded our ability to acquire nanometer and atomically resolved images of complex materials. The resulting vast datasets are typically analyze…
Convex Factorization Machine for Regression
Makoto Yamada, Wenzhao Lian, Amit Goyal +6
We propose the convex factorization machine (CFM), which is a convex variant of the widely used Factorization Machines (FMs). Specifically, we employ a linear+quadratic model and r…
Validating Network Value of Influencers by means of Explanations
Glenn S. Bevilacqua, Shealen Clare, Amit Goyal +1
Recently, there has been significant interest in social influence analysis. One of the central problems in this area is the problem of identifying influencers, such that by convinc…
Comments on "Procedures for proper validation of record critical current density claims" by Chiara Tarantini and David C. Larbalestier
Massimiliano Polichetti, Armando Galluzzi, Rohit Kumar +1
We provide comments on article titled "Procedures for proper validation of record critical current density claims" by Chiara Tarantini and David C. Larbalestier, arXiv:2410.22195.…
Tuning flux-pinning in epitaxial NdBa2Cu3O7-x films via engineered, hybrid nanoscale defect structures
Sung Hun Wee, Amit Goyal, Yuri L. Zuev +1
Epitaxial NdBa2Cu3O7-x films with a hybrid nanoscale defect structure comprised of BaZrO3 nanodot arrays aligned along the c-axis in one half of the film thickness and aligned perp…
Chirped Lambert W-kink solitons of the complex cubic-quintic Ginzburg-Landau equation with intrapulse Raman scattering
Nisha, Neetu Maan, Amit Goyal +2
In this paper, an exact explicit solution for the complex cubic-quintic Ginzburg-Landau equation is obtained, by using Lambert W function or omega function. More pertinently, we te…
A Data-Based Approach to Social Influence Maximization
Amit Goyal, Francesco Bonchi, Laks V. S. Lakshmanan
Influence maximization is the problem of finding a set of users in a social network, such that by targeting this set, one maximizes the expected spread of influence in the network.…
SAGE: Scalable Automatic Gating Ensemble for Confident Negative Harvesting in Fraud Detection
Sudheer Tubati, Amit Goyal
Music streaming fraud, where bad actors artificially inflate stream counts to manipulate chart rankings and royalty payments, poses a significant threat to streaming services and l…
Optimal tie-breaking rules
Sumit Goel, Amit Goyal
We consider two-player contests with the possibility of ties and study the effect of different tie-breaking rules on effort. For ratio-form and difference-form contests that admit…
