Stable laser-acceleration of high-flux proton beams with plasma collimation.

Laser-plasma acceleration of protons offers a compact, ultra-fast alternative to conventional acceleration techniques, and is being widely pursued for potential applications in medicine, industry and fundamental science. Creating a stable, collimated beam of protons at high repetition rates presents a key challenge. Here, we demonstrate the generation of multi-MeV proton beams from a fast-replenishing ambient-temperature liquid sheet.

MAGPIE: A Machine Learning Approach to Decipher Protein-Protein Interactions in Human Plasma.

Immunoprecipitation coupled to tandem mass spectrometry (IP-MS/MS) methods are often used to identify protein-protein interactions (PPIs). While these approaches are prone to false positive identifications through contamination and antibody nonspecific binding, their results can be filtered using negative controls and computational modeling. However, such filtering does not effectively detect false-positive interactions when IP-MS/MS is performed on human plasma samples.

Evaluation and Treatment of Baseball Pitchers: There's More to Assess than the Arm.

Injuries are commonplace in the overhead athlete, with many occurring to the shoulder and elbow. The increasing prevalence of injuries to the shoulder and elbow has been discussed at length in recent years, with increased research focus being placed on arm care for rehabilitation and prevention strategies. Even though the pitching motion is well-established as a whole-body kinetic chain movement, most attention in rehabilitation and prevention efforts is often placed on the upper extremity.

[When should a gluteus medius tendon rupture be operated on ?].

The gluteus medius allows hip abduction and stabilization of the pelvis when walking. A rupture of the gluteus medius tendon is associated with lateral hip pain, weakness, a positive Trendelenburg sign, and a limp. Diagnosis is confirmed by ultrasound or MRI.
