Method of making conical fiber optical components [PDF]

, 1969
Improved method for producing fused-fiber optical components is described. These components have a frustro-conical shape and provide high-quality light transmission with high resolution capabilities.

Multi-kilowatt single-mode ytterbium-doped large-core fiber laser

, 2009
We have demonstrated a highly efficient cladding-pumped ytterbium-doped fiber laser, generating >2.1 kW of continuous-wave output power at 1.1 µm with 74% slope efficiency with respect to launched pump power.

Linking neurogenesis, oligodendrogenesis, and myelination defects to neurodevelopmental disruption in primary mitochondrial disorders

FEBS Letters, EarlyView.
Mitochondrial remodeling shapes neural and glial lineage progression by matching metabolic supply with demand. Elevated OXPHOS supports differentiation and myelin formation, while myelin compaction lowers mitochondrial dependence, revealing mitochondria as key drivers of developmental energy adaptation.

Genome-wide identification of the pectate lyase (PEL) gene family members in Malvaceae, and their contribution to cotton fiber quality

Journal of Integrative Agriculture
Pectin is a major constituent of the plant cell wall. Pectate lyase (PEL, EC 4.2.2.2) uses anti-β-elimination chemistry to cleave the α-1,4 glycosidic linkage in the homogalacturonan region of pectin.

ATF4‐mediated stress response as a therapeutic vulnerability in chordoma

Molecular Oncology, EarlyView.
We screened 5 chordoma cell lines against 100+ inhibitors of epigenetic and metabolic pathways and kinases and identified halofuginone, a tRNA synthetase inhibitor. Mechanistically halofuginone induces an integrated stress response, with eIF2alpha phosphorylation, activation of ATF4 and its target genes CHOP, ASNS, INHBE leading to cell death ...

Assessment of Segal method for identifying crystallinity evolution in developing cotton fibers

Agricultural & Environmental Letters
The crystallinity index (CI) is an important parameter in evaluating cotton fiber quality. Due to its ease and speed in measuring CIs from X‐ray diffraction (XRD) patterns, the Segal method is popularly used.

Genetical genomics dissection of cotton fiber quality [PDF]

, 2008
Cotton fiber is a commodity of key economic importance in both developed and developing countries. The two cultivated species, Gossypium hirsutum and G. barbadense , are tetraploid (2n=1x= 52 . 2.3 Gb).

Resonant THz sensor for paper quality monitoring using THz fiber Bragg gratings

, 2013
We report fabrication of THz fiber Bragg gratings (TFBG) using CO2 laser inscription on subwavelength step-index polymer fibers. A fiber Bragg grating with 48 periods features a ~4 GHz-wide stop band and ~15 dB transmission loss in the middle of a stop ...

Cell surface interactome analysis identifies TSPAN4 as a negative regulator of PD‐L1 in melanoma

Molecular Oncology, EarlyView.
Using cell surface proximity biotinylation, we identified tetraspanin TSPAN4 within the PD‐L1 interactome of melanoma cells. TSPAN4 negatively regulates PD‐L1 expression and lateral mobility by limiting its interaction with CMTM6 and promoting PD‐L1 degradation.
