Nanophotonics, 2021 We demonstrate that electrically pumped random laser resonators, operating at terahertz (THz) frequencies, and comprising a quantum cascade laser heterostructure, can operate as sensitive photodetectors through the self-mixing effect.

Local quantum thermal susceptibility
Nature Communications, 2016 In thermodynamics, thermal properties of systems are obtained from averaging procedures which smooth out local details. Here, the authors introduce the concept of local quantum thermal susceptibility, a measure for the best achievable accuracy of ...

Archive for Mathematical Logic, 2010 In this note we will introduce a class of search problems, called nested Polynomial Local Search (nPLS) problems, and show that definable NP search problems, i.e., $Σ^b_1$-definable functions in $T^2_2$ are characterized in terms of the nested PLS.

Application and Progress of Ion Chromatography in Food Analysis
Shipin gongye ke-ji, 2022 Ion chromatography (IC) is based on the differential promotion of the substance to be tested on the ion chromatography column, so as to separate different substances, and then determine the content of the substance to be tested through the detection ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT A lethal round‐cell malignancy with an MN1::ZNF341 fusion has recently been reported in three infants. Here, we describe four further tumors, three in newborns (including monozygotic twins), and one in an adolescent. Detailed clinical, radiological, and histopathological data differentiate these tumors from their main mimics, neuroblastoma and

Probing paper ageing by label-free fluorescence lifetime microscopy
Scientific ReportsPaper ageing is a complex and irreversible process that critically affects materials ranging from packaging to cultural heritage artefacts. While both invasive and non-invasive analytical techniques exist to assess the deterioration of paper, many ...

FEBS Letters, EarlyView.This study reveals that the small GTPase Rab14 is necessary for human papillomavirus (HPV) infection and plays an essential role in the transport of virions to the trans‐Golgi network (TGN). HPV in the early endosome (EE), which harbors GTP‐bound Rab14, is transported to the TGN through the switch of Rab14 from its GTP‐bound to GDP‐bound form.

Communications BiologyIt is widely accepted that the pH of insulin granules is acidic, and that its active regulation during granule maturation plays a role in the process of insulin secretion by β-cells. Yet, a calibrated measurement of the absolute granule pH with organelle

Loss of proton‐sensing TDAG8 increases tumor progression in mouse models of colon cancer
Molecular Oncology, EarlyView.Loss of the pH‐sensing receptor TDAG8 accelerates colorectal cancer progression in mice. Animals lacking TDAG8 expression had increased tumor growth, DNA damage, and recruitment of tumor‐associated immune cells, including macrophages, neutrophils, and monocytes.
