Critical lumpy black holes in AdSp×Sq

Journal of High Energy Physics, 2021
In this paper we study lumpy black holes with AdSp × S q asymptotics, where the isometry group coming from the sphere factor is broken down to SO(q).

Cocalibrated G_2-manifolds with Ricci flat characteristic connection

, 2013
Any 7-dimensional cocalibrated G_2-manifold admits a unique connection $\nabla$ with skew symmetric torsion. We study these manifolds under the additional condition that the $\nabla$-Ricci tensor vanishes. In particular, we describe their geometry in case of a maximal number of $\nabla$-parallel vector fields.

Chern Flat and Chern Ricci-Flat Twisted Product Hermitian Manifolds

Mathematics
Let (M1,g) and (M2,h) be two Hermitian manifolds. The twisted product Hermitian manifold (M1×M2f,G) is the product manifold M1×M2 endowed with the Hermitian metric G=g+f2h, where f is a positive smooth function on M1×M2.

Matter field Kähler metric in heterotic string theory from localisation

Journal of High Energy Physics, 2018
We propose an analytic method to calculate the matter field Kähler metric in heterotic compactifications on smooth Calabi-Yau three-folds with Abelian internal gauge fields.

Soil‐applied carbon‐based biostimulants differentially affect maize and soybean grain yield and quality

Agrosystems, Geosciences &Environment, Volume 8, Issue 4, December 2025.
Abstract The use of carbon‐based biostimulants (e.g., humic acid [HA] and molasses/yeast extract [MYE]) to enhance grain yield and/or quality of maize (Zea mays L.) and soybean [Glycine max (L.) Merr.] is increasing. The objectives of this study were to (1) determine if MYE or HA use can consistently influence grain yield and quality of maize and ...

Ricci Flat Metrics, Flat Connections and $G_{2}$-Manifolds

, 2023
Inspired by considerations in $M$-theory, we prove the equivalence between the moduli spaces of (suitably complexified) torsion free $G_{2}$-structures on 7-manifolds which are families of hyperKähler ALE 4-manifolds fibered over compact flat 3-manifolds $T^{3}/K$ and certain moduli spaces of flat $G^{\mathbb{C}}_{ADE}$ connections on $T^{3}/K$.

The Human Remains From the MIS 6 Site of Grotta Del Poggio (Cilento, Southern Italy): A Taxonomic and Chronological Reassessment

American Journal of Biological Anthropology, Volume 188, Issue 4, December 2025.
ABSTRACT Objectives Grotta del Poggio is a key site for exploring the Middle Paleolithic in southern Italy, as it contains a pivotal anthropogenic deposit, mainly attributed to MIS 6, while in the Metal Ages, the cavity was used as a burial place. Excavations in the cave's deposit led to the discovery of a human molar and a human talus.

The Potential Economic and Public Health Impact of MDMA‐Assisted Group Therapy for PTSD in Ukraine

World Medical &Health Policy, Volume 17, Issue 4, Page 791-805, December 2025.
ABSTRACT The war in Ukraine has led to widespread trauma, with 6.4 million people suffering from severe, chronic posttraumatic stress disorder (PTSD). This study evaluates the cost‐effectiveness and societal impact of implementing modified group MDMA‐assisted therapy (MAT), with supplemental individual therapy for PTSD treatment in Ukraine.

Mass-deformed M2 branes in Stenzel space

Journal of High Energy Physics, 2017
We obtain finite-temperature M2 black branes in 11-dimensional supergravity, in a G 4-flux background whose self-dual part approaches a solution of Cvetič, Gibbons, Lü, and Pope, based upon Stenzel’s family of Ricci-flat Kähler deformed cones.
