Direct electron beam patterning of electro-optically active PEDOT:PSS.

The optical and electronic tunability of the conductive polymer poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) has enabled emerging applications as diverse as bioelectronics, flexible electronics, and micro- and nano-photonics. High-resolution spatial patterning of PEDOT:PSS opens up opportunities for novel active devices in a range of fields. However, typical lithographic processes require tedious indirect patterning and dry etch processes, while solution-processing methods such as ink-jet printing have limited spatial resolution.

Azimuthal Correlations within Exclusive Dijets with Large Momentum Transfer in Photon-Lead Collisions.

The structure of nucleons is multidimensional and depends on the transverse momenta, spatial geometry, and polarization of the constituent partons. Such a structure can be studied using high-energy photons produced in ultraperipheral heavy-ion collisions. The first measurement of the azimuthal angular correlations of exclusively produced events with two jets in photon-lead interactions at large momentum transfer is presented, a process that is considered to be sensitive to the underlying nuclear gluon polarization.

Laparoscopic Extraperitoneal Hernia Repair Versus Open Repair in Boys with Inguinal Hernia: A Meta-Analysis.

Objective: Pediatric inguinal hernia is a common surgical problem in boys. Open hernia repair surgery (OH) has been traditionally used to treat this condition, but it leads to complications, such as testicular complications. Laparoscopic hernia repair by using the extraperitoneal method (LHE) is performed through the percutaneous insertion of sutures and extracorporeal closure of patent vaginalis processus; thus, injury to spermatic cord structures is avoided.
