Sharp Diamond Needles for Single‐Photon Emission
Advanced Photonics Research, EarlyView.We study the morphological evolution of single‐crystal diamond needles oxidized at 650–700 °C. Electron microscopy and photoluminescence reveal temperature‐ and time‐dependent sharpening, length reduction, and surface modifications affecting tip properties.

A Breakdown of the Black Hole–Bulge Mass Relation in Local Active Galaxies
The Astrophysical JournalWe investigate the relation between black hole (BH) mass and bulge stellar mass for a sample of 117 local ( z ∼ 0) galaxies hosting low-luminosity, broad-line active galactic nuclei (AGNs).

The chemical evolution of the Galactic Bulge seen through micro-lensing events
EPJ Web of Conferences, 2012 Galactic bulges are central to understanding galaxy formation and evolution. Here we report on recent studies using micro-lensing events to obtain spectra of high resolution and moderately high signal-to-noise ratios of dwarf stars in the Galactic bulge.

The Black Hole Mass Scale of Classical and Pseudo Bulges in Active Galaxies
, 2014 The mass estimator used to calculate black hole (BH) masses in broad-line active galactic nuclei (AGNs) relies on a virial coefficient (the "$f$ factor") that is determined by comparing reverberation-mapped (RM) AGNs with measured bulge stellar velocity ...

Identification of PKN2 and MOB4 as Coordinators of Collective Cell Migration
Advanced Science, EarlyView.Through a genetic screen, PKN2 and MOB4 are identified as two proteins regulating the healing of an epithelial model wound. PKN2 promotes collective cell migration by maintaining the cohesion of cell monolayers from their lateral junctions, whereas MOB4 restrains collective cell migration and provides a lamellipodial cue for front‐rear polarity in ...

Advanced Science, EarlyView.A predictive model for 3D printability is developed by integrating rheological analysis, including the Large Amplitude Oscillatory Shear (LAOS) test, with machine learning. With prediction errors under 10%, the model shows that post‐extrusion recovery controls horizontal printability, while high‐strain‐rate nozzle flow dictates vertical printability ...

The populations of planetary nebulae in the direction of the Galactic bulge
, 2004 We have observed 44 planetary nebulae (PNe) in the direction of the Galactic bulge, and merged our data with published ones. We have distinguished, in the merged sample of 164 PNe, those PNe most likely to prtain physically to the Galactic bulge and ...

Advanced Science, EarlyView.This study elucidates the mechanism by which heat stress regulates skin pigmentation: heat stress upregulates CX3CL1 through the MYC‐WDR5‐H3K4me3 axis, thereby activating the CX3CL1/CX3CR1‐JNK signaling pathway and ultimately promoting melanogenesis. These findings provide novel potential therapeutic targets for pigmentary skin disorders.

Bulge Region as a Putative Hair Follicle Stem Cells Niche: A Brief Review
Iranian Journal of Public Health, 2017 Background: Hair follicle stem cells exist in different sites. Most of the hair follicle stem cells are reside in niche called bulge. Bulge region is located between the opening of sebaceous gland and the attachment site of the arrector pili muscle ...
