ABSTRACT As new technological innovations are rapidly introduced and changed, identifying an individual characteristic that has a persistent effect on the acceptance decisions across multiple technologies is of substantial value for successful implementation information systems. Augmenting prior work innovativeness within context technology, we developed measure adopter category (ACI) compared its effectiveness with existing personal in IT (PIIT). Further, examined two alternative models...
Zinc-ion batteries are emerging as next-generation rechargeable that can operate in aqueous electrolytes. We first examine the feasibility of open-structured VO2(B) a Zn2+ intercalation host. A bond-valence sum energy map predicts four Zn2+-ion sites (ZnC, ZnA1, ZnA2, and ZnC′) exist structure. Using first-principles calculations, we verified 0.5 mol ions be reversibly (de)intercalated with an average voltage ∼0.61 V (vs Zn2+/Zn), which is comparable experimental results. The specific...
C/NVMP allowed high electrochemical performance supported by the replace V Mn promoted easier electron transfer through lower band gap energy than Mn-free NVP and carbon coating increase electric conductivity up to 2 × 10<sup>−3</sup> s cm<sup>−1</sup>, which led superior electrode performance.
We present a new approach for object boundary extraction, called the watersnake. It is two-step snake algorithm whose energy functional minimized by dynamic programming method. more robust to local minima because it finds solution searching entire space. To reduce complexity of minimization process, watershed transformation and coarse-to-fine strategy are used. The technique compared standard methods accuracy in synthetic data applied segmentation white blood cells bone marrow images.
A Macro Fiber Composite (MFC) is a piezoelectric fiber composite which has an interdigitated electrode, rectangular cross-section and unidirectional polycrystalline piezoceramic (PZT) fibers embedded in the polymer matrix. MFC actuator much higher actuation performance flexibility than monolithic actuator. Moreover, single crystal material exhibits induced strain levels, energy density coupling those of materials. Thus, can be improved by using instead fiber. This study investigates...
Background: We investigated the differential regulation of p-p38 MAPK or p-NF- κB in male Sprague-Dawley rats with inferior alveolar nerve injury resulting from mal-positioned dental implants. For this purpose, we characterized temporal expression medullary dorsal horn and examined changes nociceptive behavior after a blockade pathways trigeminal neuropathic pain. Results: Under anesthesia, left lower second molar was extracted replaced mini implant to intentionally injure nerve. Western...
This paper investigates the use of active rotor vibration control, specifically individual blade pitch control (IBC), for a 13 600 kg (30 000 lb) class lift-offset compound helicopter to simultaneously reduce and fuselage responses while enhancing performance. The systems are modeled analyzed separately using CAMRAD II MSC.NASTRAN respectively, one-way coupled analysis is applied account effects hub vibratory loads on fuselage. study trims isolated propulsive trim approach, predicting...

We present a novel approach to perform probabilistic collision detection between high-DOF robot and imperfect obstacle representations in dynamic uncertain environments. Our formulation is designed for trajectory planning scenes, where the uncertainties are modeled using Gaussian distributions. an efficient algorithm compute probabilities obstacles. Furthermore, we prediction positions that takes into account spatial temporal uses optimization. highlight performance of our challenging...
The present study is the first to investigate participation of central cyclooxygenase (COX) pathways in modulating antinociceptive effects intracisternally administered cannabinoid on nociception induced by inflammation temporomandibular joint (TMJ) freely moving rats. Following intra-articular injection 5% formalin TMJ, nociceptive scratching behavior was recorded for nine successive 5-min intervals Sprague-Dawley Intracisternal 30 microg WIN 55,212-2, a synthetic non-subtype-selective...
Performing differential white blood cell counts in a bone marrow preparation is crucial step diagnosing various disease states. It tedious task to locate, identify, and count these classes of cells. In an active project, we are investigating the automation this task. paper, present segmentation approach which utilizes principle least commitment. We use watershed algorithm perform "oversegmentation" image where each primitive patch no bigger than one components (nucleus, cytoplasm, red cell,...
