Reconstructing Early Cenozoic Paleodrainage and Tectonic Evolution in the Southeastern Tibetan Plateau: Evidence From Detrital Zircon and Tourmaline Provenance

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 10, October 2025.
Abstract The Paleogene sedimentary basins of southeastern Tibet record sediment dispersal patterns associated with crustal deformation during the early stages of the India–Asia collision. We present detrital zircon U–Pb geochronology, tourmaline geochemistry, and petrographic data from the Gonjo and Mangkang basins that suggest a reginal interconnected

The behavior of major and trace elements of the tourmaline from the Mangavai and Ganjnameh pegmatitic rocks (Hamadan area) [PDF]

پترولوژی, 2016
The Mangavai and Ganjnameh pegmatitic rocks are part of the Alvand granitoid pluton in the Sanandaj-Sirjan zone. The composition of tourmaline in Mangavi is Schorl and that of the Ganjnameh lies in the Schorl- foitite fields.

Experimental investigation of oxygen diffusion in the peak and valley region of minibeam patterns during x‐ray irradiation

Medical Physics, Volume 52, Issue 8, August 2025.
Abstract Background Minibeam radiotherapy has demonstrated its potential to reduce normal tissue toxicity while maintaining tumor control. However, the underlying mechanisms behind this phenomenon remain unknown. Recent theoretical studies suggest a dose surrogate by diffusion of H2O2${\rm H}_2{\rm O}_2$ into the valley regions.

Australian continental‐scale heavy mineral patterns track climate, weathering and erosion

Sedimentology, Volume 72, Issue 5, Page 1430-1452, August 2025.
ABSTRACT The heavy mineral cargo of sediment is influenced by a complex and variable overprint of climate and environmental processes acting on weathered crystalline basement sources. Here, a continental‐scale heavy mineral compositional dataset of 1315 surface sediment samples, analysed via automated mineralogy, from across Australia is utilized to ...

Structural and functional connectivity in tau mutation carriers: from presymptomatic to symptomatic frontotemporal dementia

Alzheimer's &Dementia, Volume 21, Issue 7, July 2025.
Abstract INTRODUCTION Microtubule‐associated protein tau (MAPT) mutations cause frontotemporal dementia (FTD), characterised by behavioural, language, and motor impairments due to brain connectivity disruptions. We investigated structural and functional connectivity in 86 mutation carriers and 272 controls to map connectivity changes at different ...

Sex differences in clinical phenotypes of behavioral variant frontotemporal dementia

Alzheimer's &Dementia, Volume 21, Issue 4, April 2025.
Abstract INTRODUCTION Higher male prevalence in sporadic behavioral variant frontotemporal dementia (bvFTD) has been reported. We hypothesized differences in phenotypes between genetic and sporadic bvFTD females resulting in underdiagnosis of sporadic bvFTD females.

Phenotypic upregulation of hexocylceramides and ether‐linked phosphocholines as markers of human extreme longevity

Aging Cell, Volume 24, Issue 4, April 2025.
Mass spectrometry analysis of 569 lipid species showed that ceramide‐to‐hexosylceramide conversion and the preservation of ether‐linked PC levels are key phenotypic traits ensuring extreme longevity. This lipidomic signature is shaped by an intrinsic adaptive program that maintains protective mechanisms and cellular identity.
