Rarity mediates species‐specific responses of tropical reef fishes to protection

Ecology Letters, Volume 27, Issue 3, March 2024.
While controlling for the social‐environmental context, we computed 658 species‐specific models to extract the effect of high, medium and low protection of marine reef fish species. We found that nearly 40% of the species did not benefit from protection.

On the computation of finite bottom-quark mass effects in Higgs boson production [PDF]

, 2016
We present analytic results for the partonic cross-sections contributing to the top-bottom interference in Higgs production via gluon fusion at hadron colliders at NLO accuracy in QCD.

Diverse pathways for climate resilience in marine fishery systems

Fish and Fisheries, Volume 25, Issue 1, Page 38-59, January 2024.
Abstract Both the ecological and social dimensions of fisheries are being affected by climate change. As a result, policymakers, managers, scientists and fishing communities are seeking guidance on how to holistically build resilience to climate change.

Explicit calculation of multi-fold contour integrals of certain ratios of Euler gamma functions. Part 1 [PDF]

, 2016
In this paper we proceed to study properties of Mellin-Barnes (MB) transforms of Usyukina-Davydychev (UD) functions. In our previous papers [Nuclear Physics B 870 (2013) 243], [Nuclear Physics B 876 (2013) 322] we showed that multi-fold Mellin-Barnes (MB)

Complex conformal spin partial wave expansion of generalized parton distributions and distribution amplitudes

, 2005
We introduce a new representation of generalized parton distributions and generalized distribution amplitudes that is based on the partial wave decomposition with respect to the complex collinear conformal spin. This decomposition leads us to a versatile

Analytical solution to DGLAP integro-differential equation in a simple toy-model with a fixed gauge coupling

, 2016
We consider a simple model for QCD dynamics in which DGLAP integro-differential equation may be solved analytically. This is a gauge model which possesses dominant evolution of gauge boson (gluon) distribution and in which the gauge coupling does not run.

Light-like polygonal Wilson loops in 3d Chern-Simons and ABJM theory

, 2011
We study light-like polygonal Wilson loops in three-dimensional Chern-Simons and ABJM theory to two-loop order. For both theories we demonstrate that the one-loop contribution to these correlators cancels.

One-loop N-point equivalence among negative-dimensional, Mellin-Barnes and Feynman parametrization approaches to Feynman integrals

, 2003
We show that at one-loop order, negative-dimensional, Mellin-Barnes' (MB) and Feynman parametrization (FP) approaches to Feynman loop integrals calculations are equivalent.

Certain composition formulae for the fractional integral operators

, 2017
In this paper we establish some (presumably new) interesting expressions for the composition of some well known fractional integral operators $ I^{\mu}_{a+}, D^{\mu}_{a+} $,$ I^{\gamma , \mu}_{a+}$ and also derive an integral operator $\mathcal{H}^{w;m,n;
