Characterization of a Resistively Multiplexed SiPM Readout for Position-Sensitive Scintillating Fibre Radiation Detectors

Active stoppers based on scintillating fibres provide fast signal formation, fine segmentation and compact geometry. On the other hand, their implementation requires a readout that can handle many silicon photomultiplier channels and a wide range of light intensities. We present...

Coffee-ring effect enables correlative super-resolution imaging of label-free chromosomes

High-resolution chromosome imaging plays a key role in understanding chromosome structure. However, traditional methods for super-resolution (<200 nm) chromosome imaging are often complex and time-consuming, requiring purification, staining or sectioning of chromosomes. Here, we...

Paeoniflorin Attenuates Radiation-Induced Brain Injury Associated with Modulation of Microglial Polarization and ERK/MAPK Signaling

Abstract Background: Radiation-induced brain injury (RIBI) is a common side effect of cranial radiotherapy that severely impairs patients’ neurological function and quality of life. Currently, effective and safe remedies for RIBI remain limited. Paeoniflorin (PF), a key component...

The Phase Structure of QCD: Fluctuations and Correlations

The strong interaction, governed by quantum chromodynamics (QCD), shapes the structure of the visible Universe. At about 10 μs after the big bang, the quark–gluon plasma (QGP)—the primordial matter made up of quarks and gluons plus leptons, photons, and neutrinos—became cool enou...

Ferroelectric Thin‑Film Polarization‑Sensitive Photodetector Based on the Plasmon‑Enhanced Bulk Photovoltaic Effect

ABSTRACT Polarization‑sensitive photodetection is critical for advanced imaging, optical communication, and medical diagnosis technologies. Although detectors based on low‐symmetry metasurfaces or two‐dimensional materials have been widely investigated, they generally suffer from...

Identification of a nanosecond isomer of $$^{164}$$Tb

Abstract This letter reports on the identification of a new isomeric state of $$^{164}$$ 164 Tb ( $$Z=65$$ Z = 65 , $$N=99$$ N = 99 ), which was measured with the DESPEC setup at the GSI Helmholtzzentrum für Schwerionenforschung GmbH following the first relativistic fragmentation...

Statistics of Solar Filament Mass Based on CHASE Sun-as-a-star Spectroscopic Observations

Abstract Filaments are cool and dense plasmas suspended in the hot corona of the Sun and other stars. Accurately estimating their masses is of great significance for understanding subsequent eruptions and induced space weather effects, but it remains hindered by their intrinsic g...

Investigation on Ti0.94Zr0.08Cr1.0Mn0.6−xFe0.4+x (x = 0, 0.1, 0.2, 0.3, 0.4) Alloys for 25 MPa Hydrogen Compression Materials

For hydrogen refueling stations, metal hydride compressors offer a safe and efficient alternative to mechanical systems. This work systematically investigates Ti0.94Zr0.08Cr1.0Mn0.6−xFe0.4+x (x = 0, 0.1, 0.2, 0.3, 0.4) alloys for primary hydrogen compression targeting 25 MPa. All...

Exploring baryon semileptonic decays through polarization and entanglement

Abstract The unitarity of the Cabibbo–Kobayashi–Maskawa (CKM) matrix is a cornerstone of the standard model (SM). Precise tests of this unitarity require independent determinations of its elements, such as | V us |, which governs the transition between strange and up quarks. Curr...

Epigenetic multi-omics reveals the molecular regulatory mechanism underlying liver cold resistance in Hezuo pigs

Non-shivering thermogenesis is one of the adaptive modes of heat production in animals to maintain a constant core body temperature in cold environments, in which the liver plays a crucial role. However, the underlying molecular regulatory mechanisms of this process remain unclea...

Microstructural evolution of SIMP steel during martensitic transformation

SIMP steel, a reduced activation ferritic/martensitic heat–resistant steel, is a promising candidate for structural applications in future nuclear fusion reactors. Understanding the evolution of microstructure in SIMP steel is of practical importance for improving the structural...

Calibration of theMass Spectrometer of China’sChang’E-7 Lunar Soil Water Molecule Analyzer

Abstract The existence of water ice at the lunar south pole has become a major topic in contemporary deep-space exploration. China’s Chang’e-7 lunar mission is scheduled for launch in 2026. One of its primary scientific objectives is to conduct an in situ investigation of water i...

Tracking the baryon number with nuclear collisions

Baryon quantum number is found to be conserved since baryogenesis in the early Universe. Conventionally, each fractionally charged valence quark is understood to carry one-third of a baryon number. An alternative hypothesis posits that baryon number is instead carried by a baryon...

Cholesterol metabolism-immune gene prognostic model in colorectal cancer

To investigate the association between serum cholesterol and the occurrence of colorectal cancer (CRC), and to construct a prognostic model for CRC based on cholesterol metabolism-related genes (CMG), clarifying the model's relationship with immune infiltration. Serum cholesterol...
