An energy-resolving photon-counting X-ray detector for computed tomography combining silicon-photomultiplier arrays and scintillation crystals

Communications Engineering
X-ray photon-counting computed tomography (PCCT) has garnered considerable interest owing to its low-dose administration, high-quality imaging, and material decomposition characteristics.

Scintillator detectors of AugerPrime [PDF]

Proceedings of 35th International Cosmic Ray Conference — PoS(ICRC2017), 2017
As part of the upgrade of the Pierre Auger Observatory, called AugerPrime, scintillator detectors will be mounted on top of all water-Cherenkov detectors (WCDs) of the surface array. By combining the data from WCDs with those of scintillator surface detectors (SSDs), we can derive information needed to reconstruct the energy and composition of cosmic ...

Ultra precise timing with SiPM-based TOF PET scintillation detectors

, 2009
The combination of SiPMs with fast and bright scintillators, such as LaBr3:Ce, seems very promising for application in time-of-flight (TOF) PET. We therefore conducted a series of experiments with the goal of obtaining the best possible timing resolution

Simulation of [gamma]-quanta registration with energies below 20 MeV in scintillation detectors using Geant4 toolkit [PDF]

, 2020
In the nuclear physics experiments in case of study of reactions with low cross-sections it is much more beneficial to create a simulation of experiment to estimate detectors assembly than obtain it experimentally. In this report the simulation of [gamma]

Captivated by Kinesin

Cytoskeleton, EarlyView.
ABSTRACT Few proteins have inspired as much curiosity as kinesin. Since its discovery 40 years ago, kinesin has become one of the best understood molecular machines in biology, yet it continues to reveal new questions about how cells organize and move their contents.

Real-Time Dose Measurement in Brachytherapy Using Scintillation Detectors Based on Ce³⁺-Doped Garnet Crystals

Crystals
Conventional detectors based on ionization chambers, semiconductors, or thermoluminescent materials generally cannot be used to verify the in vivo dose delivered during brachytherapy treatments with γ-ray sources.

Increased Insulin Action, Glucose Metabolism and Muscle Function in Supervillin‐Knockout and Supervillin‐Mutant Mice

Cytoskeleton, EarlyView.
ABSTRACT We here describe mouse models with complementary homozygous Svil mutations. In skeletal muscle, Svil‐Mut mice express the Svil‐encoded N‐terminus fused to the βgal‐neo gene‐trap tag and lack the highly conserved archvillin C‐terminus; Svil‐KO mice lack expression of all known Svil‐encoded proteins; and Svil‐LoxP mice contain loxP sites for ...

Orthodentine‐osteodentine and osteocytic‐anosteocytic transition inferred from Silurian stem chondrichthyan dermal jawbones with ever‐white teeth overgrown by brown denticles

Developmental Dynamics, EarlyView.
Abstract Background The dentigerous jawbones of a 423‐million‐year‐old stem chondrichthyan (ischnacanthid acanthodian) carry a characteristic combination of multi‐row non‐shedding white teeth with brownish overgrowing denticles. The color distinction makes it a good model for observing the interaction between two odontode lineages, but the nature of ...
