INTRODUCTION: Piezoelectric bone surgery is a relatively new alternative for bone-related procedures in oral and maxillofacial surgery. It represents an innovative technique as it offers the maxillofacial surgeon the opportunity to make precise bone cuts without damaging any soft tissue and providing a blood less surgical field. Correction of facial asymmetries is still a major problem in need of an adequate solution. Neurosensory damage to the inferior alveolar nerve can be an adverse effect of surgical correction of hemimandibular hyperplasia...

Intrinsically high mobility and large absorption coefficient endow inorganic halide perovskites (IHPs) with great promise for high-performance photodetectors (PDs), which, however, are being hindered by the low carrier extraction and transport efficiency of the solution assembled films. Here, we report on a general strategy to enhance the film conductivity of perovskites that conductive nanonets were constructed with carbon nanotubes (CNTs) to provide fast carriers tracks. As a result, the CsPbBr3 nanosheet/CNT composite films exhibit high conductivity and the advantages are demonstrated by the high performances of corresponding planar PDs...

Three barriers investigators often encounter when conducting longitudinal work with homeless or other marginalized populations are difficulty tracking participants, high rates of no-shows for follow-up interviews, and high rates of loss to follow-up. Recent research has shown that homeless populations have substantial access to information technologies, including mobile devices and computers. These technologies have the potential both to make longitudinal data collection with homeless populations easier and to minimize some of these methodological challenges...

This article reports the characterization of WTe<sub>2</sub> ultrathin flakes devices with characterization of magnetoresistance and Hall resistivity. We found that ultrathin flakes of WTe<sub>2</sub> do not exhibit magnetoresistance saturation when subject to high fields, in a manner similar to their bulk characteristic. The linearity of Hall resistivity in our devices could confirm the compensation of electrons and holes. By relating experimental results to a classic two-band model, we demonstrate that the lower magnetoresistance values may be caused by decreased carrier mobility in our samples...

The ubiquity and mobility of contemporary computing devices has enabled users to consume content, anytime, anywhere. Yet, when we need to create content, touch input is far from perfect. When coupled with touch input, the stylus should enable users to simultaneously ink, manipulate the page, and switch between tools with ease, so why has the stylus yet to achieve universal adoption? Michelle Annett's thesis sought to understand the usability barriers and tensions that have prevented stylus input from gaining traction and reaching widespread adoption...

Charge carrier transport in oriented COF thin films is an important factor for realizing COF-based optoelectronic devices. We describe how highly oriented electron-donating BDT-COF thin films serve as a model system for a directed charge transport study. Oriented BDT-COF films were deposited on different electrodes with excellent control over film roughness and topology, allowing for high quality electrode-COF interfaces suitable for device fabrication. Hole-only devices were constructed to study the columnar hole-mobility of the BDT-COF films...

BACKGROUND: Some 222 million women worldwide have unmet needs for contraception; they want to avoid pregnancy, but are not using a contraceptive method, primarily because of concerns about side effects associated with most available methods. Expanding contraceptive options-particularly fertility awareness options that provide women with information about which days during their menstrual cycles they are likely to become pregnant if they have unprotected intercourse-has the potential to reduce unmet need...

Energetic disorder in quantum dot solids adversely impacts charge carrier transport in quantum dot solar cells and electronic devices. Here, we use ultrafast transient absorption spectroscopy to show that homogeneously broadened PbS quantum dot arrays (σhom(2):σinh(2)>19:1, σinh/kBT<0.4) can be realized if quantum dot batches are sufficiently monodisperse (δ ≲ 3.3%). Homogeneous linewidth is found to be an inverse function of quantum dot size, monotonically increasing from ~25 meV for the largest quantum dots (5...

Severe burn injuries are associated with hypermetabolic response and increased catabolism. These lead to a vast loss of muscle mass and reduced muscle strength and function. Therefore, the aim of this study is to determine the impact of severe burn injuries on lower-limb muscular strength, balance, and mobility level in adults. Forty burned adults with burned TBSA (burned TBSA) ≥40% participated in this study. The peak torque and total work of quadriceps and knee flexors were calculated at 150°/sec using Biodex isokinetic dynamometer...

Tracking people's behaviors is a main category of cyber physical social sensing (CPSS)-related people-centric applications. Most tracking methods utilize camera networks or sensors built into mobile devices such as global positioning system (GPS) and Bluetooth. In this article, we propose a non-intrusive wireless fidelity (Wi-Fi)-based tracking method. To show the feasibility, we target tracking people's access behaviors in Wi-Fi networks, which has drawn a lot of interest from the academy and industry recently...

Numerous efforts have been devoted to boost the efficiency of thermally activated delayed fluorescence (TADF) devices; however, strategies to suppress the device efficiency roll-off are still in urgent need. Here, a general and effective approach to suppress the efficiency roll-off of TADF devices is proposed, that is utilizing TADF materials as the hosts for TADF emitters. Bearing small singlet-triplet splitting (ΔEST) with donor and acceptor units, TADF materials as the hosts possess the potential to achieve matched frontier energy levels with the adjacent transporting layers, facilitating balanced charge injection, as well as bipolar charge transport mobilities, beneficial to the balanced charges transportation...

Wrinkle-free graphene was used to form the source-drain electrodes in thin film transistors based on a zinc tin oxide (ZTO) semiconductor. A 10 nm thick titanium adhesion layer was applied prior to transferring a conductive graphene film on top of it by chemical detachment. The formation of an interlayer oxide between titanium and graphene allows the achievement of uniform surface roughness over the entire substrate area. The resulting devices were thermally treated in ambient air, and a substantial decrease in field effect mobility is observed with increasing annealing temperature...
