Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT The study examines how narrative disclosure tones (NDTs) and corporate governance mechanisms (CGMs) affect sustainability reporting practices (SRP) in an emerging economy. Data from 125 non‐financial firms in Pakistan, spanning 2011–2022, are utilized. SRP is measured using both GRI and the novel IFRS S1 standards‐based indices. Three NDTs are

Mimetic-f(Q) gravity: Cosmic reconstruction and energy conditions
Nuclear Physics BIn this study, we present a approach to mimetic gravity incorporating a non-zero nonmetricity tensor with vanishing torsion and curvature, establishing a generalized mimetic-f(Q) gravity framework.

Study on fracture parameter calibration and failure characteristics of rock with hole and crack
Deep Underground Science and Engineering, EarlyView.The SIF and plastic zone equations for a single hole and crack have been derived. The model's failure state leads to the identification of four types of cracks. The plastic zone increases with increased brittleness and decreased crack length. Abstract Cracks within the surrounding rock of roadways significantly affect their stability and failure ...

Lagrange Multiplier Rules for Optimization Problems
, 1984 .This paper is devoted to show that a given element, set,cone and functions satisfy the proposed condition if､ and only if､ a Lagrange multiplier rule is satisfied, and that a Lagrange multiplier rule is satisfied by a solution of an optimization problem

Decoupling Capacitor Placement Optimization With Lagrange Multiplier Method
, 2020 This paper proposes a decoupling capacitor placement optimization method based on the cavity model and Lagrange multiplier. The variable conditions associating with coordinates (x,y) of input impedance expression based on the cavity model are combined ...

Biophysical processes of morphogenesis in lizard lungs
Developmental Dynamics, EarlyView.Abstract Background The lungs of squamate reptiles (lizards and snakes) are highly diverse, exhibiting single chambers, multiple chambers, transitional forms with two to three chambers, along with a suite of other anatomical features, including finger‐like epithelial projections into the body cavity known as diverticulae.

Lagrange Multiplier Method for Convex Programs [PDF]
Proceedings of the National Academy of Sciences, 1975 The problem of minimizing a convex function that is subject to the constraint that a number of other convex functions be nonpositive can be treated by the Lagrange multiplier method. Such a treatment was revived by Kuhn and Tucker and further studied by many other scientists.

Developing a macroecology for human‐altered ecosystems
Ecography, EarlyView.Although anthropogenically‐induced ecological disruptions are fundamentally important in defining ecosystem properties, they are largely overlooked by macroecological theory. Anthropogenic disruptions and their effects are generally not comparable to one another, nor to disturbances that are part of natural disturbance regimes.
