Geochemical characteristics and genesis of element enrichment of niobium-rich-rare earth metal layer in Longtan Formation of Zhina coalfield

open access: yesMeitian dizhi yu kantan
BackgroundWith the increasing demand for strategic metals and the gradual depletion of traditional metal deposit resources, coal and coal-bearing rock series are considered to be potential sources of rare metals, and coal series associated has become one

Fabrication of mesoscopic Nb wires using conventional e-beam lithographic techniques

open access: yes, 2001
Conventional electron beam lithography has been used to fabricate mesoscopic Nb wires with a superconducting transition temperature above 7.0 K. The typical line width and the thickness were 200 nm and 45 nm respectively.

Network divergence analysis identifies adaptive gene modules and two orthogonal vulnerability axes in pancreatic cancer

open access: yesMolecular Oncology, EarlyView.
Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

NBS :

open access: yes, 1980
The compositional homogeneity, microstructure, hardness, electrical conductivity and mechanical properties of 2219 aluminum alloy plates are influenced by the process variables during casting, rolling and thermomechanical treatment. The details of these relationships wre investigated for correctly processed 2219 plate as well as for deviations caused ...

Modeling of an air-to-air exchanger with dual-core in cascade connection

open access: yesMethodsX, 2021
With the current leaning towards finding effective solutions to maintain a good indoor air quality (IAQ) inside houses and buildings and to simultaneously reduce the energy consumption, air-to-air exchangers with heat/energy recovery have emerged as one ...

Somatic mutational landscape in von Hippel–Lindau familial hemangioblastoma

open access: yesMolecular Oncology, EarlyView.
The causes of central nervous system (CNS) hemangioblastoma in Von Hippel–Lindau (vHL) disease are unclear. We used Whole Exome Sequencing (WES) on familial hemangioblastoma to investigate events that underlie tumor development. Our findings suggest that VHL loss creates a permissive environment for tumor formation, while additional alterations ...

NON-DEVELOPING PREGNANCY. THE ROLE OF HORMONAL CONTRACEPTION IN REHABILITATION TREATMENT

open access: yesАкушерство, гинекология и репродукция, 2016
Non-developing pregnancy (NB) is main factor of reproductive losses. The stress developed after the NB like after the abortion which accompanied with excitation of the hypothalamic-pituitary system.

Development of the nanobody display technology to target lentiviral vectors to antigen-presenting cells [PDF]

open access: yes, 2012
Lentiviral vectors (LVs) provide unique opportunities for the development of immunotherapeutic strategies, as they transduce a variety of cells in situ, including antigen-presenting cells (APCs). Engineering LVs to specifically transduce APCs is required

On nB-algebras [PDF]

open access: yesMathematica Moravica, 2003
It is proved that an \(n\)-ary analog of \(B\)-algebras described by \textit{J. R. Cho} and \textit{H. S. Kim} [Quasigroups Relat. Syst. 8, 1-6 (2001; Zbl 0994.08003)] can be uniquely determined by an \(n\)-ary group.

Dual PI3K/AKT and CDK4/6 inhibition reveals selective sensitivity in an SHH medulloblastoma stem cell model

open access: yesMolecular Oncology, EarlyView.
Targeted therapy was evaluated in SHH medulloblastoma using neuroepithelial stem cell (NES) and tumor‐derived NES‐like (tNES) models in 2D monolayers and 3D spheroids. PI3K, AKT, and CDK4/6 inhibitors had minimal effects in NES but markedly reduced viability and growth and induced apoptosis in tNES cells, revealing distinct therapeutic vulnerabilities.
