Bragg scattering at one-dimensional corrugated substrates allows to improve the light outcoupling from top-emitting organic light-emitting diodes (OLEDs). The OLEDs rely on a highly efficient phosphorescent pin stack and contain metal electrodes that introduce pronounced microcavity effects. A corrugated photoresist layer underneath the bottom electrode introduces light scattering. Compared to ...

cer cachexia, predisposing him to skin integrity issues (Fig. 3). Others have noted similar issues, and Jackson et al5 proposed specific padding of the head and face to reduce ulcers during prone positioning. Therapists should be cognizant of the potential for these types of facial ulcers (usually associated with mask ventilation), which have been identified by Medicare as avoidable complicatio...

The initial fixation strengths of two spiked-washer designs were evaluated using human femurs and fascia lata tissue. Fascia lata was attached to the femur using the fixation devices, and then each femur-washer-fascia lata complex was loaded in tension to failure. Load-elongation curves were recorded, the initial failure load, initial failure displacement, stiffness, ultimate load, and ultimate...

We develop a simple method to improve external quantum efficiencies (EQEs) of OLEDs under a wide range of current density. An insulating inorganic ultrathin layer (LiF) was sandwiched between exciton formation layer and electron transporting layer. A maximal EQE of 5.9% in a DCM based fluorescent OLED, which far exceeds the theoretical upper limit of 3.7%, was obtained under the current density...

Among the power drills (Electrical/Pneumatic/Battery) used in Orthopedic surgery, battery drill has got several advantages. Surgeons in low resource settings could not routinely use Orthopedic battery drills (OBD) due to the prohibitive cost of good drills or poor quality of other drills. "Hardware" or Engineering battery drill (HBD) is a viable alternative to OBD. HBD is easy to procure, rugge...

Mason type III fractures of the radial head are treated by open reduction and internal fixation, resection or prosthetic joint replacement. When internal fixation is performed, fixation of the radial head to the shaft is difficult and implant-related complications are common. Furthermore, problems of devascularisation of the radial head can result from fixation of the plate to the radial neck. ...

We consider the rotational motion of an elongated nanoscale object in a fluid under an external torque. The experimentally observed dynamics could be understood from analytical solutions of the Stokes equation, with explicit formulae derived for the dynamical states as a function of the object dimensions and the parameters defining the external torque. Under certain conditions, multiple analyti...

A new control method is proposed for tension regulation in a web transport system. It is based on a unique active disturbance rejection control (ADRC) strategy, which actively compensates for dynamic changes in the system, and unpredictable external disturbances. A simulation of an industrial application is used to provide realism. The results show the effectiveness of the proposed tension cont...

UNLABELLED Pin tract inflammation and/or infection are common with the use of external fixation devices. Pin sites need to be managed to help prevent complications. There are a variety of regimens proposed for pin care in the literature. The authors present an efficient and simplified approach for addressing pin care protocol using cord locks with the use of compression sponges for external fix...

Sporulation vs. competence provides a prototypic example of collective cell fate determination. The decision is performed by the action of three modules: 1) A stochastic competence switch whose transition probability is regulated by population density, population stress and cell stress. 2) A sporulation timer whose clock rate is regulated by cell stress and population stress. 3) A decision gate...
