Differentially driven skid-steering vehicles are often considered for navigation in outdoor terrains. However, the control of such vehicles is challenging because the wheels must skid laterally to follow a curved path, and motion stability can be lost as a result of excess skidding due to the position of the instantaneous center of rotation (ICR). To accommodate for the potential loss of stabil...

Carrying excess body fat is a leading cause of cancer. Epidemiologic evidence gives strong clues about the mechanisms that link excess adiposity to risk for several cancer sites. For postmenopausal breast cancer and endometrial cancer, the hyper-estrogenic state that is induced by excess body fatness is the likely cause. For esophageal cancer and gallbladder cancer, chronic local inflammation i...

Auger recombination (AR) can be an important loss mechanism for optoelectronic devices, but it is typically not very efficient at low excitation densities. Here we show that in conductive quantum-dot solids, AR is the dominant charge carrier decay path even at excitation densities as low as 10⁻³ per quantum dot, and that AR becomes faster as the charge carrier mobility increases. Monte Carlo si...

A QoS restoration scheme for VP-based ATM network is proposed and its related characteristics are evaluated. The proposed scheme is a state-independent restoration scheme using a disjoint path group. A VP assignment and capacity planning problem using disjoint path group are formulated. When a failure occurs, failed working VPs are switched to protection paths with the same QoS level using a si...

In this study, we address the problem of selecting the optimal end-to-end paths for link loss inference in order to improve the performance of network tomography applications, which infer the link loss rates from the path loss rates. Measuring the path loss rates using end-to-end probing packets may incur additional traffic overheads for networks, so it is important to select the minimum path s...

Worldwide Interoperability for Microwave Access (WiMAX) is the latest broadband wireless technology for terrestrial broadcast services in Metropolitan Area Networks (MANs). WiMAX has potential success in its line-of-sight (LOS) and non line-of-sight (NLOS) conditions which operating below 11 GHz frequency. Estimation of path loss is very important in initial deployment of wireless network and c...

Bariatric surgery is an operation on the stomach and/or intestines that helps patients with extreme obesity to lose weight. Even if bariatric surgery, compared with traditional obesity treatment, is more effective in reducing BMI, this approach does not achieve equal results in every patient. More, following bariatric surgery common problems are body image dissatisfaction and body disparagement...

We present new excess risk bounds for randomized and deterministic estimators for general unbounded loss functions including log loss and squared loss. Our bounds are expressed in terms of the information complexity and hold under the recently introduced v-central condition, allowing for high-probability bounds, and its weakening, the v-pseudoprobability convexity condition, allowing for bounds...

Background: Bariatric surgery is an effective treatment for several patients, but some may not achieve sufficient weight loss. We therefore evaluated predictors of adequate loss defined as ≥50% excess (EWL).
