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 ...

purpose : to report a rare case of spontaneous resorption of a membranous congenital cataract in an adult woman with no systemic disease, with complete absorption of the central lens material, anterior and posterior capsules of the right eye, and partial absorption of the lens material with intact anterior capsule in the left eye. case report : a 23-year-old woman was referred to our clinic suf...

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...

Bu çalışmada 5, 10 ve 15 cm yüksekliklerdeki Hız Kesici Tümseklerin (HKT) toplu yolcu taşıma faaliyetlerinde sıklıkla kullanılan minibüs, midibüs otobüs sınıfındaki taşıtlar üzerinde hızı azaltma konusundaki performansları değerlendirilmiştir. HKT’lerin taşıt hızlarını performansları, kamera görüntüleri aracılığıyla taşıtların mesafe ortalamalı hız değerleri okunarak araştırılmıştır. Öncelikle,...
