Quantification of Age and Sex Ratio Differences between Trial and Target Population for New Drugs

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Clinical trials are essential to understand the benefit‐harm profile of new drugs. Lack of adequate representation in age and sex ratio in clinical trials can result, for example, in higher side effects for underrepresented patients. We quantified differences in age and sex ratios between trial and target populations of new drugs approved by the FDA ...

Seasonal estimates of ozone and secondary organic aerosol formation from volatile organic compounds in a rural atmosphere of India

open access: yesAtmospheric Environment: X
Volatile Organic Compounds (VOCs) serve as precursors for tropospheric ozone (O3) and Secondary Organic Aerosol (SOA) formation. The formation of O3 and SOA are the indicators of the oxidative capacity specific to a given chemical environment.

The scaling attractor and ultimate dynamics for Smoluchowski's coagulation equations

open access: yes, 2006
We describe a basic framework for studying dynamic scaling that has roots in dynamical systems and probability theory. Within this framework, we study Smoluchowski's coagulation equation for the three simplest rate kernels $K(x,y)=2$, $x+y$ and $xy$.

Charting Resource Efficiency Practices Across European Firms: A Multilevel Analysis

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT The circular economy (CE) is a key sustainability paradigm, prompting European Union (EU) organizations and policymakers to move beyond linear production and consumption models. The study aimed to assess the implementation patterns of nine CE activities among EU companies and to explore how the implementation of these CE activities relates to ...

Early dark energy and scalarization in a scalar-tensor model

open access: yesPhysics Letters B
We present a model in which the Gauss-Bonnet invariant holds the quintessence at a fixed point, respecting an initial Z2 symmetry in the radiation-dominated era.

Critical Discourse Analysis in Corporate Reports: Legitimation Strategies in the Context of Environmental Controversies

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study examines the use of environmental disclosure as a strategic tool to manage legitimacy crises in a mining company, adopting critical discourse analysis (CDA) as the main methodology. Focusing on a case of environmental disaster, this research reveals how corporate narratives can be manipulated to minimize responsibility and reinforce

Scalar-Gauss-Bonnet model, the coincidence problem and the gravitational wave speed

open access: yesPhysics Letters B
We introduce a dynamical dark energy model wherein quintessence interacts with both the Gauss-Bonnet invariant and dark matter. Initially, the Gauss-Bonnet invariant stabilizes the quintessence at a fixed point, resulting in a negligible density of dark ...

Kosterlitz-Thouless transitions and phase diagrams of the interacting monomer-dimer model on a checkerboard lattice

open access: yes, 2014
Using the tensor network approach, we investigate the monomer-dimer models on a checkerboard lattice, in which there are interactions (with strength $\nu$) between the parallel dimers on half of the plaquettes.

Mechanical property variation mechanisms of granite subjected to real‐time high temperatures and subsequent cooling treatment

open access: yesDeep Underground Science and Engineering, EarlyView.
This study investigates the coupled thermo‐mechanical behavior of granite during heating and cooling through a combination of laboratory tests and finite element analysis. The thermal conductivity, mineral composition, mass loss rate, micro‐crack observation, and thermal fracture characteristics of granite under various temperature conditions are ...
