Cross-facility absolute charge calibration of scintillating screens for laser wakefield accelerated beam diagnostics.

Scintillation screens are widely used to diagnose high-charge density, low-average current electron beams from laser wakefield accelerators (LWFAs). However, the absolute response between emitted photons and electron charge has only been calibrated at a limited number of facilities, and there have been discrepancies between these calibrations. In this report, we comprehensively revised the absolute charge calibration of two high relative brightness scintillating screens of LANEX Regular (Carestream) and PI200 (Mitsubishi) by employing the high-brightness photoinjector at the National Synchrotron Radiation Research Center (NSRRC), which provides electron beams with variable charges (50-350 pC per pulse) and energies (26.

Methods: A retrospective study was conducted, including 20 patients with facial asymmetry (menton deviation >8 mm) who underwent BSSRO with intended manual condyle positioning at a single institution. Cone beam computed tomography (CBCT) images were obtained preoperatively (T0), 2 days postoperatively (T1), and 6 months postoperatively (T2).

Effect of PEGylation on the Adsorption and Binding Strength of Plasma Proteins to Nanoparticle Surfaces.

The adsorption of plasma proteins (human serum albumin, immunoglobulin γ-1, apolipoproteins A-I and E-III) onto polystyrene surfaces grafted with polyethylene glycol (PEG) at different grafting densities is simulated using an all-atom PEG model validated by comparing the conformations of isolated PEG chains with previous simulation and theoretical values. At high PEG density, the grafted PEG chains extend like brushes, while at low density, they significantly adsorb to the surface due to electrostatic attraction between polystyrene amines and PEG oxygens, forming a PEG layer much thinner than its Flory radius. Free energy calculations show that PEGylation can either increase or decrease the binding strength between proteins and surfaces, to an extent dependent on PEG density and specific proteins involved, in agreement with experiments.

Repeated Copulation and Guarding, and Their Relationship With Male and Female Morphological Traits in the Water Scorpion .

Insects copulate multiple times not only with different mates but also with the same mate, which is called repeated copulation. It occurs as a repeated alternation between copulation and mate-guarding, leading to the prolonged physical attachment between males and females. Particularly, in species where males forcefully grasp females, attempt to mate without courtship and exhibit repeated copulations, male and female morphological traits are expected to be associated with mating characteristics.
