Random phase-free kinoform for large objects

We propose a random phase-free kinoform for large objects. When not using the random phase in kinoform calculation, the reconstructed images from the kinoform are heavy degraded, like edge-only preserved images. In addition, the kinoform cannot record an entire object that exceeds the kinoform size because the object light does not widely spread. In order to avoid this degradation and to widely spread the object light, the random phase is applied to the kinoform calculation; however, the reconstructed image is contaminated by speckle noise. In this paper, we overcome this problem by using our random phase-free method and error diffusion method

A Clinical Trial Evaluating the Usefulness of Tailored Antimicrobial Prophylaxis Using Rectal-culture Screening Media Prior to Transrectal Prostate Biopsy: A Multicenter, Randomized Controlled Trial

The aim of this report is to introduce an on-going, multicenter, randomized controlled trial to evaluate whether tailored antimicrobial prophylaxis guided by rectal culture screening prevents acute bacterial prostatitis following transrectal prostate biopsy (TRPB). Patients will be randomized into an intervention or non-intervention group; tazobactam-piperacillin or levofloxacin will be prophylactically administered according to the results of rectal culture prior to TRPB in the intervention group whereas levofloxacin will be routinely given in the non-intervention group. The primary endpoint is the occurrence rate of acute bacterial prostatitis after TRPB. Recruitment begins in April, 2021 and the target total sample size is 5,100 participants

Molecular Communication for Health Care Applications

Molecular communication is a new communication paradigm and uses molecules as a communication carrier. In molecular communication, information is encoded onto molecules at senders and the molecules propagate to receivers in a controlled manner. The receivers, upon receiving the molecules, decode the encoded information and react biochemically. Molecular communication provides means to deliver information-encoded molecules to receivers and allows biological and artificially-created components to communicate with each other. This paper describes a design of a molecular communication system that may enable future health care applications. 1

Palladium-Catalyzed Cycloaddition of Alkynyl Aryl Ethers with Internal Alkynes via Selective Ortho C–H Activation

Alkynyl aryl ethers react with internal alkynes through selective ortho C–H activation by a palladium(0) catalyst to give substituted 2-methylidene-2<i>H</i>-chromenes. The alkynoxy group acts as a directing group to promote ortho C–H functionalization. Deuterium-labeling experiments indicated that the arylpalladium hydride complex is a key intermediate via oxidative addition. Various functional groups tolerate the present transformation to give the corresponding products
