Estimating National and Foreign Trade Elasticities Using Generalized Transport Costs

Journal of Regional Science, Volume 65, Issue 2, Page 471-496, March 2025.
ABSTRACT We introduce the definition of two distinct trade elasticities corresponding to imports from regions located in the same country (national elasticities) and foreign regions located in other countries (foreign elasticities). We resort to a three‐tier nested CES utility structure to derive the corresponding demand gravity equations.

Empirical‐Process Limit Theory and Filter Approximation Bounds for Score‐Driven Time Series Models

Journal of Time Series Analysis, EarlyView.
ABSTRACT This article examines the filtering and approximation‐theoretic properties of score‐driven time series models. Under specific Lipschitz‐type and tail conditions, new results are derived, leading to maximal and deviation inequalities for the filtering approximation error using empirical process theory.

Rapid Translation of the Early Coding Region Promotes Premature Transcription Termination, Reducing Protein Expression in Escherichia coli

Molecular Microbiology, EarlyView.
A run of consecutive fast‐translated codons (right) within the first 30 codons of lacZ (top) causes loss of the downstream transcript at positions coinciding with previously mapped intragenic Rho‐dependent termination sites (middle), and a corresponding loss of β‐galactosidase activity (bottom).

INEQUALITIES OF HERMITE-HADAMARD-FEJE´R TYPE FOR CONVEX FUNCTIONS AND CONVEX FUNCTIONS ON THE CO-ORDINATES IN A RECTANGLE FROM THE PLANE

Taiwanese Journal of Mathematics, 2008
We establish necessary and sufficient conditions for efficiency of multiobjective fractional programming problems involving r-invex functions. Using the optimality conditions, we investigate the parametric type dual, Wolfe type dual and Mond-Weir type dual for multiobjective fractional programming problems concerning r-invexity.

Panoramic voltage‐sensitive optical mapping of contracting hearts using cooperative multiview motion tracking with 12 cameras

The Journal of Physiology, EarlyView.
Abstact figure legend A panoramic 3D optical mapping system was developed, enabling imaging of action potential waves across the entire strongly deforming ventricular surface of beating isolated hearts. The system comprises 12 high‐speed cameras and a soccerball‐shaped imaging chamber with 48 light‐emitting diodes (LEDs).

Milne-type inequalities for co-ordinated convex functions

Filomat
In this research, our objective is to formulate a unique identity for Milne-type inequalities involving for functions of two variables having convexity on co-ordinates over [?, ?] ? [?, ?]. By employing this identity, we establish some new inequalities of the Milne-type for co-ordinated convex functions.

Large‐flowered stapeliad Edithcolea grandis (Apocynaceae: Asclepiadoideae) is pollinated by dung‐ and blood‐feeding African face flies (Muscidae: Musca xanthomelas)

TAXON, Volume 75, Issue 5, October 2026.
Abstract The more than 360 species of stem‐succulent stapeliads in the tribe Ceropegieae represent a perfect example for species radiation and diversification in response to pollination by flies. In the majority of species, the myiophilous flowers have visual and olfactory characteristics that suggest carrion or dung mimicry.

Two Closely Related Butterflies Show Pseudo‐Concordant Patterns of Geographic Differentiation in a Heterogeneous Mountain Region

Ecology and Evolution, Volume 16, Issue 8, August 2026.
Phylogeographic pseudo‐concordance among species—coincident spatial structuring coupled with differing levels of intraspecific differentiation—has rarely been documented in heterogeneous regions. We report a clear case in two mountain butterfly species and show how the high density of spatial sampling and the integration of phenotypic and genomic ...

A note on the Hermite-Hadamard inequality for convex functions on the co-ordinates [PDF]

Journal of Mathematical Inequalities, 2014
In this paper, we obtain some new Hermite-Hadamard-type inequalities for convex functions on the co-ordinates. We conclude that the results obtained in this work are the refinements of the earlier results. Mathematics subject classification (2010): 26D15, 52A40.
