Three dimensional flutter analysis of a rectangular sheet based on the unsteady lifting surface theory and wind-tunnel experiments

open access: yesNihon Kikai Gakkai ronbunshu, 2016
This paper presents a three-dimensional flutter analysis of a rectangular sheet in an axial fluid flow. The unsteady fluid force acting on the sheet surface is calculated using Doublet-point method based on the unsteady lifting surface theory.

Convergence analysis of an Inexact Infeasible Interior Point method for Semidefinite Programming [PDF]

open access: yes, 2004
In this paper we present an extension to SDP of the well known infeasible Interior Point method for linear programming of Kojima,Megiddo and Mizuno (A primal-dual infeasible-interior-point algorithm for Linear Programming, Math. Progr., 1993).

Hilbert series and plethystics: paving the path towards 2HDM- and MLRSM-EFT

open access: yesJournal of High Energy Physics, 2019
Effective Field Theory (EFT) technique is one of the most elegant ways to capture the impact of high scale theory, if any, at some low energy by incorporating higher mass dimensional (≥5) effective operators ( O $$ \mathcal{O} $$ i ).

Developmental programmes drive cellular plasticity, disease progression and therapy resistance in lung adenocarcinoma

open access: yesMolecular Oncology, EarlyView.
This study shows that lung adenocarcinomas exploit developmental branching morphogenesis to acquire a therapy resistant basal‐like tumour cell state. This process was found to be regulated by combined TP53 loss‐of‐function and type‐I interferon signalling, identifying a novel axis for biomarker and therapeutic target discovery.

GPUs Based Material Point Method for Compressible Flows [PDF]

open access: yes, 2023
Particle-In-Cell (PIC) methods such as the Material Point Method (MPM) can be cast in formulations suitable to the requirements of data locality and fine-grained parallelism of modern hardware accelerators such as Graphics Processing Units (GPUs).
