We show numerically that the response of simple amorphous solids (elastic networks and particle packings) to a local force dipole is characterized by a lengthscale lc that diverges as unjamming is approached as lc ∼ (z - 2d)(-1/2), where z ≥ 2d is the mean coordination, and d is the spatial dimension, at odds with previous numerical claims. We also show how the magnitude of the lengthscale lc i...

INTRODUCTION: Ultrasonic energy surgical cutting devices are used to simultaneously cut and coagulate soft tissue and vessels. However, the extent of nerve damage that may result from their application in close proximity to a nerve is not clear. Hence, the purposes of this study were to determine the effects of ultrasonic (US) energy surgical cutting devices on sciatic nerve function when appli...

We describe a new liquid-target system for low-debris laser-plasma soft x-ray sources. The system is based on a microscopic liquid jet and is experimentally evaluated for 0.7–1 keV proximity lithography and water-window x-ray microscopy applications. Compared to an existing liquid-droplet target, this target system has the same low debris emission, high x-ray photon flux, and narrow spectral ba...

A compact, high-brightness and practically debris-free laser-plasma soft x-ray source for proximity x-ray lithography is described. The target of the source is small liquid fluorocarbon droplets injected into vacuum with a piezoelectrically vibrated nozzle. Emission from heliumand hydrogenlike fluorine in the 1.2–1.7 nm wavelength range was determined to ;2310 photons/~sr-pulse!, which correspo...

In radiation therapy, especially using intensity modulated radiation therapy (IMRT), a high dose of ionizing radiation is delivered to the patient and, therefore, the bone health is a major concern for young patients. What is more, many tumors, like soft tissue sarcomas, are located in close proximity to bone. High energy radiation unavoidably exerts negative impacts not only on bone physiologi...
