Supersymmetric K field theories and defect structures
, 2011 We construct supersymmetric K field theories (i.e., theories with a non-standard kinetic term) in 1+1 and 2+1 dimensions such that the bosonic sector just consists of a nonstandard kinetic term plus a potential.

The subset argument and consistency of MLE in GLMM: Answer to an open problem and beyond [PDF]
, 2013 We give answer to an open problem regarding consistency of the maximum likelihood estimators (MLEs) in generalized linear mixed models (GLMMs) involving crossed random effects.

Advanced NanoBiomed Research, EarlyView.Despite significant advances, most academic research fails to result in medical products that benefit patients. This guide shares five key steps to help researchers close that gap: set clear goals, test thoroughly, protect ideas, build diverse teams, and partner with industry.

Models of Weak Theories of Truth
, 2017 In the following paper we propose a model-theoretical way of comparing the "strength" of various truth theories which are conservative over PA. Let $\mathfrak{Th}$ denote the class of models of PA which admit an expansion to a model of theory Th.

Observations and nonstandard FRW models
The Astrophysical Journal, 1987 The observational predictions of various nonstandard cosmological models which have an FRW metric as their space-time geometry are investigated. The general numerical predictions of the models are found to be in accord with actual observations; in particular, they predict a current relative velocity of the Galaxy with respect to the CMB consistent with

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT In this study, the actual route of methylene blue (MB) dye adsorption by using fabricated polyfunctional activated carbon–copper oxide nanowires (AC@CuO‐NWs) from bulky wastewater bodies has been investigated. To better understand the exact pathway of the adsorption process, a prominent statistical physics formalism or grand canonical ...

Business Strategy and the Environment, EarlyView.ABSTRACT The agri‐food industry faces major sustainability challenges, requiring a shift in companies' approach. Circular economy principles offer a promising path by enhancing resource efficiency, reducing waste, and valorizing by‐products. However, the integration of sustainability and circularity practices remains limited, especially in developing ...
