Advances in Therapeutic Antibody Discovery and Development Targeting G Protein‐Coupled Receptors

Pharmacology Research &Perspectives, Volume 14, Issue 1, February 2026.
ABSTRACT G protein‐coupled receptors (GPCRs) are integral to numerous biological processes and are associated with various diseases across all therapeutic areas. Consequently, GPCRs present substantial potential for antibody‐based therapies. This review offers an overview of the therapeutic GPCR‐antibody target landscape and examines the diversity ...

Linearizing Generalized Kahler Geometry

, 2007
The geometry of the target space of an N=(2,2) supersymmetry sigma-model carries a generalized Kahler structure. There always exists a real function, the generalized Kahler potential K, that encodes all the relevant local differential geometry data: the ...

Topological M-theory as Unification of Form Theories of Gravity [PDF]

, 2004
We introduce a notion of topological M-theory and argue that it provides a unification of form theories of gravity in various dimensions. Its classical solutions involve G_2 holonomy metrics on 7-manifolds, obtained from a topological action for a 3-form

The versal deformation of small resolutions of conic bundles over P1×P1${\mathbb {P}}^1\times {\mathbb {P}}^1$ with two sections blown down

Journal of the London Mathematical Society, Volume 113, Issue 2, February 2026.
Abstract Twistor spaces are certain compact complex three‐folds with an additional real fibre bundle structure. We focus here on twistor spaces over P2#P2#P2${\mathbb {P}}^2\#{\mathbb {P}}^2\#{\mathbb {P}}^2$. Such spaces are either small resolutions of double solids or they can be described as modifications of conic bundles.

On the paper “Bundle gerbes” by Michael Murray

Journal of the London Mathematical Society, Volume 113, Issue 1, January 2026.
Abstract The article gives a brief survey of Murray's notion of bundle gerbes as introduced in his 1996 paper published in the Journal of the London Mathematical Society, together with some of its applications.

Beyond the Hodge theorem: Curl and asymmetric pseudodifferential projections

Journal of the London Mathematical Society, Volume 113, Issue 1, January 2026.
Abstract We develop a new approach to the study of spectral asymmetry. Working with the operator curl:=∗d$\operatorname{curl}:={*}\mathrm{d}$ on a connected oriented closed Riemannian 3‐manifold, we construct, by means of microlocal analysis, the asymmetry operator — a scalar pseudodifferential operator of order −3$-3$.

Accommodation of Dental Variations During Jaw Growth in Ungulate Mammals

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 344, Issue 8, Page 487-504, December 2025.
Using geometric morphometrics, we compared the covariation pattern of the dentition and the palate during growth in 23 ungulate species. ABSTRACT The growth of teeth and jaw bones is intimately linked in vertebrates, especially in mammals due to their specialized dentition and limited body growth.

Dual spaces of geodesic currents

Journal of Topology, Volume 18, Issue 4, December 2025.
Abstract Every geodesic current on a hyperbolic surface has an associated dual space. If the current is a lamination, this dual embeds isometrically into a real tree. We show that, in general, the dual space is a Gromov hyperbolic metric tree‐graded space, and express its Gromov hyperbolicity constant in terms of the geodesic current.

Topological K‐theory of quasi‐BPS categories for Higgs bundles

Journal of Topology, Volume 18, Issue 4, December 2025.
Abstract In a previous paper, we introduced quasi‐BPS categories for moduli stacks of semistable Higgs bundles. Under a certain condition on the rank, Euler characteristic, and weight, the quasi‐BPS categories (called BPS in this case) are noncommutative analogues of Hitchin integrable systems.
