Let (M, I) be a compact Kähler manifold admitting a hypercomplex structure (M, I, J,K). We show that (M, I, J,K) admits a natural HKT-metric. This is used to construct a holomorphic symplectic form on (M, I).

This is the full volume of Abstracts from 35th Himalayan-Karakoram-Tibet Workshop (HKT) on “Geosciences for People’s Prosperity and Sustainable Development” November 02-04, 2022, Pokhara, Nepal.

A hypercomplex manifold is a manifold equipped with three complex structures I, J,K satisfying the quaternionic relations. Let M be a 4-dimensional compact smooth manifold equipped with a hypercomplex structure, and E be a vector bundle on M . We show that the moduli space of anti-self-dual connections on E is also hypercomplex, and admits a strong HKT metric. We also study manifolds with (4,4)...

KtrAB belongs to the Trk/Ktr/HKT superfamily of monovalent cation (K+ and Na+) transport proteins that closely resemble K+ channels. These proteins underlie a plethora of cellular functions that are crucial for environmental adaptation in plants, fungi, archaea, and bacteria. The activation mechanism of the Trk/Ktr/HKT proteins remains unknown. It has been shown that ATP stimulates the activity...

The 3-hydroxykynurenine transaminase (3-HKT) gene plays a vital role in the development of malaria parasites by participating in the synthesis of xanthurenic acid, which is involved in the exflagellation of microgametocytes in the midgut of malaria vector species. The 3-HKT enzyme is involved in the tryptophan metabolism of Anophelines. The gene had been studied in the important global malaria ...

Managing multiple knowledge transfers between headquarters and subsidiaries, among also within each of these units is crucial for multinational corporations’ (MNCs) survival. Therefore, this article aims to uncover the main factors influencing internal in MNCs—including intra-unit units, namely, conventional, horizontal, reverse transfers. To achieve goal, a systematic literature review (SLR) w...
