5G new radio design:why/how to extend/innovate from LTE

open access: yesDianxin kexue, 2019
Driven by the 5G visions including “wireless infrastructure to connect the world”, ITU has defined the three main usage scenarios of 5G: eMBB, mMTC, and uRLLC, and the consequent requirements (performance metrics) are defined as well.

New radio telescope

open access: yesEos, Transactions American Geophysical Union, 1984
A new radio telescope to be placed atop 4205‐m‐high Mauna Kea in Hawaii will be the largest telescope of its kind ever built, and will open up previously unexplored submillimeter wavelengths to observation by astronomers when it begins operations in early 1986.

Mutant p53R273H disrupts PDPK1 homodimerization and contributes to PDPK1 activation

open access: yesMolecular Oncology, EarlyView.
How mutant p53R273H drives AKT signaling is unclear. We show that p53R273H, but not wild‐type, directly binds PDPK1 via a mutation‐dependent conformational change. This interaction disrupts inhibitory PDPK1 homodimerization and enhances AKT phosphorylation.

Unusual imaging presentation of infantile atypical Kawasaki disease

open access: yesIndian Journal of Radiology and Imaging, 2016
Kawasaki disease is a systemic medium vessel vasculitis of unknown etiology affecting children under 5 years of age. There are no specific diagnostic tests, and thus, the diagnosis of the disease is primarily made on the basis of clinical criteria ...

Raman‐based label‐free microscopic analysis of the pancreas in living zebrafish larvae

open access: yesFEBS Open Bio, EarlyView.
Forward stimulated Raman scattering (F‐SRS) and epi coherent anti‐Stokes Raman scattering (E‐CARS) allow label‐free discrimination of distinct subcellular structures in the pancreas of living zebrafish larvae. Given the straightforward applicability, we anticipate broad implementation of Raman microscopy in other organs and across various biomedical ...

UiO‐66 metal–organic frameworks in biomedicine: From structural tunability to bioimaging, photodiagnostics, and photodynamic cancer therapy

open access: yesFEBS Open Bio, EarlyView.
UiO‐66(Zr) metal–organic frameworks are chemically stable, biocompatible, and highly tunable nanomaterials. Their modular structure enables controlled drug delivery, multimodal bioimaging, and light‐activated photodynamic therapy, supporting integrated diagnostic and therapeutic (theranostic) applications in cancer and biomedical research.

New Radio Telescopes [PDF]

open access: yesHighlights of Astronomy, 1986
AbstractNearly all of the exciting discoveries in radio astronomy have come from new instruments or techniques which have provided new frequencies, high sensitivity, higher spatial or time resolution, or improved image quality. Since the last General Assembly a number of major new radio telescopes have been completed while construction of others have ...
