Solving the n $n$‐Player Tullock Contest

Journal of Public Economic Theory, Volume 28, Issue 2, April 2026.
ABSTRACT The n $n$‐player Tullock contest with complete information is known to admit explicit solutions in special cases, such as (i) homogeneous valuations, (ii) constant returns, and (iii) two contestants. But can the model be solved more generally?

Linking sap flow and tree water deficit in an unmanaged, mixed beech forest during the summer drought 2022

Plant Biology, Volume 28, Issue 3, Page 747-761, April 2026.
Sap flow and reversible stem shrinkage upon water depletion are strongly correlated under extreme drought conditions, but they respond differently to drought and cannot be used interchangeably when assessing tree response to drought. Abstract Temperate mixed forests are currently experiencing severe drought conditions and face increased risk of ...

Between Order and Confusion: Clearing up Structural Misconceptions in Carbon Materials Nomenclature

Angewandte Chemie International Edition, Volume 65, Issue 11, 9 March 2026.
Despite the versatile use of carbon materials, inconsistent terminology and inadequate characterization – especially regarding graphene structures based on sp2‐hybridized carbon atoms – often cause confusion. This perspective clarifies terms like graphite, graphitic carbon, non‐graphitic carbon, and amorphous carbon by aligning IUPAC definitions with X‐

CO2 Reduction on Copper‐Nitrogen‐Doped Carbon Catalysts Tuned by Pulsed Potential Electrolysis: Effect of Pulse Potential

Advanced Functional Materials, Volume 36, Issue 21, 12 March 2026.
This study demonstrates that pulsed potential electrolysis significantly improves CO2 reduction performance on copper‐nitrogen doped carbon electrodes. The formation of cationic copper sites and metallic clusters as a function of applied intermittent potential leads to notable selectivity changes compared to potentiostatic reduction.

Microsphere Autolithography—A Scalable Approach for Arbitrary Patterning of Dielectric Spheres

Advanced Functional Materials, Volume 36, Issue 19, 5 March 2026.
MicroSphere Autolithography (µSAL) enables scalable fabrication of patchy particles with customizable surface motifs. Focusing light through dielectric microspheres creates well defined, tunable patches via a conformal poly(dopamine) photoresist. Nearly arbitrary surface patterns can be achieved, with the resolution set by the index contrast between ...

MATHEMATICAL MODELING OF THE INFLUENCE OF RELAXATION PROCESSES ON THE TEMPERATURE FIELD IN AN ELASTIC HALF-SPACE

Российский технологический журнал, 2017
The article examines the relaxation processes that occur in an elastic solid medium when it is heated and cooled, especially their influence on the temperature field. Besides, we considered in this paper the heat equation of parabolic type arising in the

Performance of large virus removal filters during AAV processing: Influence of flux and process disruptions

Biotechnology Progress, Volume 42, Issue 2, March/April 2026.
Abstract As adeno‐associated viral vectors (AAV) continue to advance through the clinical pipeline, effective downstream purification strategies must be developed to ensure bulk drug purity and safety. AAV are produced within mammalian cells, bringing forth risks associated with viral contamination.

Steepest Descent Method in the Wolfram Language and Mathematica System

, 2019
The gradient method, known also as the steepest descent method, includes related algorithms with the same computing scheme based on a gradient concept. The illustrious French mathematician Augustin-Louis Cauchy proposed the method in 1847, much more before the appearing of modern computers.
