Radiological protection and safety: Putting patients first
The concept of radiation safety has always been a hot topic, especially with the late reports pointing to increased hazards with chronic radiation exposure for patients and medical personnel alike.

Halation in image intensifiers [PDF]
Halation effects in microchannel plate intensifiers are discussed. It is shown that infilling of line profiles observed in absorption-line spectra taken with four-stage magnetically focused intensifiers cannot be explained by such a mechanism; it is suggested that slow phosphor decay may instead be a cause of the ...

Intensifiers and image schemas: Schema type determines intensifier type [PDF]
This paper develops a theory whereby the type of intensifier that a source word grammaticalizes as is determined by the semantics of the source word.

Investigating transcription factor dynamics in health and disease using FRAP
FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...

Animals must match their growth rate to available nutrients. We show that in Drosophila larvae, the nutrient‐sensing TOR kinase controls growth by regulating levels of TFAM, a key regulator of mitochondrial function, in the adipose tissue. When nutrients are abundant, high TOR activity suppresses TFAM, lowering mitochondrial bioenergetic activity and ...

Photogrammetric calibration of the NASA-Wallops Island image intensifier system [PDF]
An image intensifier was designed for use as one of the primary tracking systems for the barium cloud experiment at Wallops Island. Two computer programs, a definitive stellar camara calibration program and a geodetic stellar camara orientation program ...

Ultrasound or image intensifier for closed femoral nailing
We describe a method of closed, unlocked nailing for femoral fractures using ultrasound instead of an image intensifier. Radiography was used only to confirm that the guide wire had been passed into the intramedullary canal of both fragments. The method

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry
EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...

Development and Testing of a Novel Microstrip Photocathode ICCD for Lunar Remote Raman Detection
The intensified charge-coupled device (ICCD), known for its exceptional low-light detection performance and time-gating capability, has been widely applied in remote Raman spectroscopy systems.

Image-intensifier photography of simulated showers in large-area layers of plastic scintillator
Preliminary results are presented of some tests which have been made to determine the feasibility of using an image-intensifier camera to photograph showers developing within an ionization calorimeter containing large sheets of plastic scintillator. The
