Oct 24, 2020
Seasonal animal migration is a widespread phenomenon. At the species level, it has been shown that many migratory animal species track similar climatic conditions throughout the year. However, it remains unclear whether such a...
A Molecular-Splicing Strategy for Constructing a Near-Infrared Fluorescent Probe for UDP-Glucuronosyltransferase 1A1
Xiangge Tian, Tao Liu, Yinhua Ma, Jian Gao, Lei Feng, Jingnan Cui, Tony D. James, Xiaochi Ma
Nov 08, 2021
UDP-glucuronosyltransferase 1A1 (UGT1A1) is a vital metabolic enzyme responsible for the clearance of endogenous substances and drugs. Hitherto, the development of fluorescent probes for UGTs was severely restricted due to...
Standard model and supersymmetric flavor puzzles at the CERN large hadron collider
Can the Large Hadron Collider explain the masses and mixings of the known
fermions? A promising possibility is that these masses and mixings are
determined by flavor symmetries that also govern new particles that will appear
at...
Shifted peak
We propose a method for determining the mass difference between two
particles, \slep_1 and \slep_2, that are nearly degenerate, with \Delta{m},
defined as m_2-m_1, being much less than m_1. This method applies when (a)...
Near infrared ultrafast pump-probe spectroscopy with ZrF4-BaF2-LaF3-AlF3-NaF fiber supercontinuum
We report on the performance of a setup designed for femtosecond pump-probe spectroscopy in the near infrared (NIR) spectral region. We generate a supercontinuum (SC) probe by coupling 140 fs light pulses at 1550 nm into a...
Argumentation-based reasoning about plans, maintenance goals, and norms
In a normative environment, an agent's actions are directed not only by its goals but also by the norms activated by its actions and those of other actors. The potential for conflict between agent goals and norms makes...
Computational modeling of the EGFR network elucidates control mechanisms regulating signal dynamics.
Argumentation-based reasoning about plans, maintenance goals, and norms
In a normative environment, an agent's actions are directed not only by its goals but also by the norms activated by its actions and those of other actors. The potential for conflict between agent goals and norms makes...
A Simple Molecular Design Strategy for Delayed Fluorescence toward 1000 nm.
Daniel G Congrave, Bluebell H Drummond, Patrick J Conaghan, Haydn Francis, Saul TE Jones, Clare P Grey, Neil C Greenham, Dan Credgington, Hugo Bronstein
Nov 04, 2019
Harnessing the near-infrared (NIR) region of the electromagnetic spectrum is exceedingly important for photovoltaics, telecommunications, and the biomedical sciences. While thermally activated delayed fluorescent (TADF)...
Detection of early neoplasia in Barrett's esophagus using lectin-based near-infrared imaging
André A Neves, Massimiliano di Pietro, Maria O'Donovan, Dale J Waterhouse, Sarah E Bohndiek, Kevin M Brindle, Rebecca C Fitzgerald
Feb 09, 2018
BACKGROUND AND STUDY AIMS: Endoscopic surveillance for Barrett's esophagus (BE) is limited by long procedure times and sampling error. Near-infrared (NIR) fluorescence imaging minimizes tissue autofluorescence and optical...

22.8%-Efficient Single-Crystal Mixed-Cation Inverted Perovskite Solar Cells with a Near-Optimal Bandgap
Abdullah Y Alsalloum, Bekir Turedi, Khulud Almasabi, Xiaopeng Zheng, Rounak Naphade, Samuel D Stranks, Omar F Mohammed, Osman M Bakr
Apr 14, 2021
Expanding the near-infrared (NIR) response of perovskite materials to approach the ideal bandgap range (1.1-1.4 eV) for single-junction solar cells is an attractive step to unleash the full potential of...
Novel near-infrared II aggregation-induced emission dots for in vivo bioimaging.

Jun 13, 2018
We measure the quantum depletion of an interacting homogeneous Bose-Einstein condensate and confirm the 70-year-old theory of Bogoliubov. The observed condensate depletion is reversibly tunable by changing the strength of the...
