Holomorphic field theories and higher algebra

Bulletin of the London Mathematical Society, Volume 57, Issue 10, Page 2903-2974, October 2025.
Abstract Aimed at complex geometers and representation theorists, this survey explores higher dimensional analogs of the rich interplay between Riemann surfaces, Virasoro and Kac‐Moody Lie algebras, and conformal blocks. We introduce a panoply of examples from physics — field theories that are holomorphic in nature, such as holomorphic Chern‐Simons ...

Structure‐Function Relationships of Biomass‐Derived Materials for Zinc Metal Protection

Advanced Science, Volume 12, Issue 34, September 11, 2025.
This review analyses the mechanism of zinc anode degradation, focuses on the protective roles of the four major functional groups of carboxyl, amino, hydroxyl, and sulfonic acid groups in biomass materials, reveals the structure‐function relationship and synergistic effects of functional groups, and looks forward to the challenges and directions of ...

Gauge-invariant on-shellZ 2 in QED, QCD and the effective field theory of a static quark

Zeitschrift f�r Physik C Particles and Fields, 1991
We calculate theon-shell fermion wave-function renormalization constantZ 2 of a general gauge theory, to two loops, inD dimensions and in an arbitrary covariant gauge, and find it to be gauge-invariant. In QED this is consistent with the dimensionally regularized version of the Johnson-Zumino relation: d logZ 2/da 0=i(2π)−D e 0

The Quest for the Quark‐Gluon Plasma From the Perspective of Dynamical Models of Relativistic Heavy‐Ion Collisions

Astronomische Nachrichten, Volume 346, Issue 7-8, September 2025.
ABSTRACT The physics of heavy‐ion collisions is one of the most exciting and challenging directions of science for the last four decades. On the theoretical side one deals with a non‐abelian field theory, while on the experimental side today's largest accelerators are needed to enable these studies.

QCD corrections to large-mt electroweak effects in Δr. An effective field theory point of view

Physics Letters B, 1995
By using effective field theory techniques for the standard model, we discuss the issue of what $ $ scale is the appropriate one in the QCD corrections to the large-$\mt$ electroweak contributions to $ r$. This needs the construction of an effective field theory below the top quark.

Intraindividual Variability as a Large Source of Trait Variation in Clonal Tundra Dwarf Shrubs Along Elevation and Latitude Gradients

Global Ecology and Biogeography, Volume 34, Issue 9, September 2025.
ABSTRACT Aim Intraindividual trait variability (iITV), which is the variability among repeated architectural units within an individual, may represent a crucial dimension of functional diversity in plant eco‐evolutionary dynamics. Although inter‐ and intraspecific trait variability have been widely studied, the extent of iITV remains largely overlooked.

Linkage and association of preserved cognitive function in the midwestern Amish at a higher genetic risk of Alzheimer's disease

Alzheimer's &Dementia, Volume 21, Issue 8, August 2025.
Abstract INTRODUCTION Genetic factors promoting cognitive preservation in high‐risk older adults for Alzheimer's disease (AD) risk remain understudied. Among Midwestern Amish with elevated AD genetic risk, we hypothesized ranking sibships by mean genetic risk scores during linkage analysis would reveal loci influencing preserved cognition.

Gauge theories with non-trivial backgrounds

, 2014
We review our most recent results in formulating gauge theories in the presence of a background field on the basis of symmetry arguments only. In particular we show how one can gain full control over the dependence on the background field of the ...

Two Micron‐Size Dark Dimensions

Fortschritte der Physik, Volume 73, Issue 8, August 2025.
Abstract Two extra dimensions of micron scale might simultaneously address the gauge and cosmological hierarchy problems. In this paper various observational bounds in scenarios with one and two large extra dimensions are examined, to see if they are compatible with the micron scale.
