Investigation of Thermal Compatibility of Various Cathode Materials with Li6.25Al0.25La3Zr2O12 Solid Electrolyte for All-Solid-State Rechargeable Lithium Batteries (2017)

Aluminum-doped lithium lanthanum zirconate (Li 6.25 Al 0.25 La 3 Zr 2 O 12 , Al-LLZ) has a relatively high Li + -ion conductivity of ~10 -4 S cm -1 at room temperature and a wide electrochemical window enabling to use both lithium-metal anode and high potential cathodes, so that it has been focused as a promising solid electrolyte for all-solid-state rechargeable lithium batteries with high energy density. Several kinds of fabrication methods, which usually include heat treatment processes, have been utilized to fabricate cathode on Al-LLZ. However, the effect of heat treatments on the formation of impurities at the interface between Al-LLZ and cathode has not been fully understood yet. In this study, we investigated the thermal compatibility of conventional cathode materials (LiCoO 2 , LiMn 2 O 4 and LiFePO 4 ) with Al-LLZ by X-ray diffraction (XRD) and charge-discharge tests. The XRD analysis showed that LiCoO 2 /Al-LLZ mixture is stable up to 800°C, but impurities are formed in LiMn 2 O 4 /Al-LLZ mixture and LiFePO 4 /Al-LLZ mixture at 600 °C and 400 °C, respectively. This result indicates that the limit of heat treatment temperature for the formation of electrode/Al-LLZ interface strongly depends on the kind of electrode materials.
OC01.04: AI‐guided auto‐detecting model for identification of pulmonary veins in second trimester sonographic screening examination of the fetal heart (2020)

Total anomalous pulmonary venous connection (TAPVC) is a very rare but severe congenital heart disease that is difficult to detect before birth. Since fetal pulmonary veins (PV) are too small to be detected on still images alone, they are easily missed in 2nd trimester sonographic screening examination of the fetal heart. It is needed to find normal fetal pulmonary veins in all normal cases to pick up fetuses with TAPVC before birth. We have developed a novel artificial intelligence (AI) - guided auto-detecting fetal cardiac screening model. In this study, we evaluated how successful our AI model was in detecting the PV. Data were acquired using 2nd trimester screening of normal fetal hearts, using fetal cardiac ultrasound videos of the level of the stomach to the neck vessels. The training dataset consisted of 8,182 frames from 247 normal fetal cardiac ultrasound videos, in which experts had annotated the correct positions of 18 different cardiac substructures. Thirty-seven normal videos were used as a test dataset to verify the detection of the PV. We calculated the mean value of the probabilities (mP-PV) of PV identification in anteroposterior slice images. Then, we evaluated the precision of PV detection. The mP-PV were plotted on graphs along with sweep scanning of the 4-chamber view. The graph showed multiple peaks, which represented a high probability for PVs. All slice images of high peaks showed pulmonary venous connections to the left atrium, with a precision rate of 93.6%. Our AI-guided auto-detecting model was able to detect pulmonary veins in 2nd trimester sonographic screening examination. The model could be the basis of future technology for the detection of fetal TAPVC.

Dynamic graph query primitives for SDN-based cloudnetwork management (2012)

The need to provide customers with the ability to configure the network in current cloud computing environments has motivated the Networking-as-a-Service (NaaS) systems designed for the cloud. Such systems can provide cloud customers access to virtual network functions, such as network-aware VM placement, real time network monitoring, diagnostics and management, all while supporting multiple device management protocols. These network management functionalities depend on a set of underlying graph primitives. In this paper, we present the design and implementation of the software architecture including a shared graph library that can support network management operations. Using the illustrative case of all pair shortest path algorithm, we demonstrate how scalable lightweight dynamic graph query mechanisms can be implemented to enable practical computation times, in presence of network dynamism.
Template‐Assisted Synthesis of Self‐Doped Polyaniline: Morphological Effects of Templates on the Conductivity (2007)

Abstract Self‐doped sulfonated polyaniline (PSA) has been synthesized on the surface of micellar nanoparticles made from positively charged surfactants by biocatalysis. The conformation forced by the electrostatic charge interactions between the positively charged micelle and the negatively charged PSA increases the conductivity of the PSA by three orders of magnitude. The pure PSA recovered from ion exchange, however, shows quite similar electrical properties compared with sulfonated polyanilines reported earlier. The increased conductivity of PSA complexes is as a result of the increased charge carrier concentration caused by a certain conformational locking. magnified image
Techniques and considerations for nanoindentation measurements of polymer thin film constitutive properties (1998)

Modulus and yield strength determinations from nanoindentation experiments of thin poly(methyl methacrylate) (PMMA) polymer films have been investigated. The modulus was calculated from flat punch theory and showed a large effect of the substrate, hydrostatic pressure, and surface topography. Substrate corrections were possible in some cases but often resulted in erroneous or negative values due to large penetration depths with respect to the film thickness and differences in the stiffness of the coating and substrate. Hydrostatic pressures up to 600 MPa were exerted by a conical and cube corner indenter tip and influenced the modulus and yield strength measurements. Due to the non-linear deformation behavior of the PMMA films, however, hydrostatic pressure corrections tended to underestimate the modulus. The yield strength was measured based on Tabor's approximation using the unloading curve and was compared with measurements using plastic zone predictions and compression test data. Yield strength calculations from plastic zone images were lower in every case than those calculated from compliance, showing the viscoelastic nature of the material.
A New GNSS Synchronization Scheme (2009)

Due to multiple side-peaks in the binary offset carrier (BOC) autocorrelation function, BOC signal synchronization is one of the most challenging tasks for global navigation satellite systems (GNSSs) including Galileo and global positioning system (GPS). Recently, a novel correlation function with reduced side-peaks was proposed for BOC signal synchronization by Julien; however, Julien's correlation function still has the side-peaks and can be possible only for sine phased BOC(n, n), where n is the ratio of the pseudo random noise (PRN) code rate to 1.023 MHz. In this paper, we propose a new correlation function for BOC signal synchronization, investigating how multiple side-peaks arise in BOC autocorrelation function. The proposed correlation function does not have any side-peaks and can be generated for any type of BOC signal, sine/cosine phase BOC(n, n), where k is the ratio of a PRN chip duration to the period of a square wave sub-carrier used in BOC modulation. In addition, an efficient correlator structure is presented for generating the proposed correlation function.

An energy-efficient, fast FPGA hardware architecture for OpenCV-Compatible object detection (2012)

The presence of cameras and powerful computers on modern mobile devices gives rise to the hope that they can perform computer vision tasks as we walk around. However, the computational demand and energy consumption of computer vision tasks such as object detection, recognition and tracking make this challenging. At the same time, a fixed vision hard core on the SoC contained in a mobile chip may not have the flexibility needed to adapt to new situations, or evolve as new algorithms are discovered. This may mean that computer vision on a mobile device is the killer application for FPGAs, and could motivate the inclusion of FPGAs, in some form, within modern smartphones. In this paper we present a novel hardware architecture for object detection, that is bit-for-bit compatible with the object classifiers in the widely-used open source OpenCV computer vision software. The architecture is novel, compared to prior work in this area, in two ways: its memory architecture, and its particular SIMD-type of processing. The implementation, which consists of the full system, not simply the kernel, outperforms a same-generation technology mobile processor by a factor of 59 times, and is 13.5 times more energy-efficient.
Metabolism of the preimplantation embryo: 40 years on (2012)

This review considers how our understanding of preimplantation embryo metabolism has progressed since the pioneering work on this topic in the late 1960s and early 1970s. Research has been stimulated by a desire to understand how metabolic events contribute to the development of the zygote into the blastocyst, the need for biomarkers of embryo health with which to improve the success of assisted conception technologies, and latterly by the 'Developmental Origins of Health and Disease' (DOHaD) concept. However, arguably, progress has not been as great as it might have been due to methodological difficulties in working with tiny amounts of tissue and the low priority assigned to fundamental research on fertility and infertility, with developments driven more by technical than scientific advances. Nevertheless, considerable progress has been made in defining the roles of the traditional nutrients: pyruvate, glucose, lactate, and amino acids; originally considered as energy sources and biosynthetic precursors, but now recognized as having multiple, overlapping functions. Other nutrients; notably lipids, are beginning to attract the attention they deserve. The pivotal role of mitochondria in early embryo development and the DOHaD concept, and in providing a cellular focus for metabolic events is now recognized. Some unifying ideas are discussed; namely 'stress-response models' and the 'quiet embryo hypothesis'; the latter aiming to relate the metabolism of individual preimplantation embryos to their subsequent viability. The review concludes by updating the state of knowledge of preimplantation embryo metabolism in the early 1970s and listing some future research questions.
Computational Modeling of Hot-Spot Identification and Control in 3-D Stacked Chips with Integrated Cooling (2013)

In 3-D chip stacks, the electronic design may lead to a variety of different hot-spot scenarios and through-silicon-via (TSV) arrangements and distributions. In the present work, the influence and implications of the integrated water-cooling, TSV distribution, and size on the control of inhomogeneous hot-spots in such stacks is investigated. The numerical model consists of a row of 50 inline cylindrical micropin fins (of different size) inside a microcavity. Material properties are modeled as temperature-dependent, and the Reynolds number ranges from 60 to 180. An optimal design of hot-spots arrangements and TSV sizes is found to reduce the maximal temperature in the chip by up to 20%, and increase the average heat transfer by up to 30%.
Wide band gap materials for field emission devices (1997)

An analysis of wide band gap materials from the point of view of their application in cold emission devices is presented, and criteria of material choice for device application are discussed. Not only material but also technological parameters are taken into consideration. Among the material parameters, the following were found to be the most important; electron affinity, dielectric constant, thermal conductivity, melting point, chemical and physical robustness. The major technological parameter is compatibility of the material deposition process with commercially available facilities and other steps of cathode fabrication. It was shown that wide band gap materials are most effective for emission if deposited on sharp conductive tips. Experimental results from diamond, AlN, c-BN, and SiO2 field emitters are presented and some possible mechanisms explaining their I–V characteristics are discussed.
Probe configuration study for the metamaterial aperture imager (2015)

We investigate a metamaterial imager (metaimager) consisting of one transmitting metamaterial panel and a collection of broadband receiving probes. Image reconstruction is performed by interrogating a scene with a set of radiative measurement modes encoded in the frequency response of the metamaterial panel. The image quality is a function of the ability of the receiving probes to capture the reflected energy. Here, the number and configuration of the receiving probe antennas is investigated. It is demonstrated that increasing the number of probe antennas and distributing their placement in space increases the effective receiver aperture size and the number of measurement modes, enhancing the image reconstruction for the metamaterial imager. The imaging of a smiley face target is performed using one-probe and five-probe metaimager configurations and successfully reconstructed images are demonstrated.

Triplet pulse sequence for superior microbubble/tissue contrast (2004)

A triplet pulse sequence is proposed for imaging with superior microbubble/tissue selectivity. This sequence utilizes the difference in nonlinearity between the nonlinear propagation in tissue and the nonlinear scattering by microbubbles. Three-time transmit/receive are performed with transmit pulses having the same envelope and a phase shift by 120/spl deg/, and the received echo signals are summed. Numerical analysis of the microbubble scattering and the propagation in tissue predicted the selectivity superior to the conventional pulse inversion sequence by more than 20 dB in an ideal case. An experiment using a prototype scanner with a Doppler flow phantom and a contrast agent demonstrated an improvement in the selectivity by 15 dB at a typical acoustic amplitude in B-mode imaging at 2 MHz.
Neuronal nucleus and cytoplasm volume deficit in children with autism and volume increase in adolescents and adults (2015)

The most severe deficit of both neuronal nucleus and cytoplasm volume in 4-to 8-year-old autistic children appears to be a reflection of early developmental alterations that may have a major contribution to the autistic phenotype. The broad range of functions of the affected structures implies that their developmental and age-associated abnormalities contribute not only to the diagnostic features of autism but also to the broad spectrum of clinical alterations associated with autism. Lack of clinical improvement in autistic teenagers and adults indicates that the observed increase in neuron nucleus and cytoplasm volume close to control level does not normalize brain function.
The regulatory function of self-conscious emotion: Insights from patients with orbitofrontal damage. (2003)

Although once considered disruptive, self-conscious emotions are now theorized to be fundamentally involved in the regulation of social behavior. The present study examined the social regulation function of self-conscious emotions by comparing healthy participants with a neuropsychological population--patients with orbitofrontal lesions--characterized by selective regulatory deficits. Orbitofrontal patients and healthy controls participated in a series of tasks designed to assess their social regulation and self-conscious emotions. Another task assessed the ability to infer others' emotional states, an appraisal process involved in self-conscious emotion. Consistent with the theory that self-conscious emotions are important for regulating social behavior, the findings show that deficient behavioral regulation is associated with inappropriate self-conscious emotions that reinforce maladaptive behavior. Additionally, deficient behavioral regulation is associated with impairments in interpreting the self-conscious emotions of others.
Human African trypanosomiasis: pharmacological re-engagement with a neglected disease (2020)

This review discusses the challenges of chemotherapy for human African trypanosomiasis (HAT). The few drugs registered for use against the disease are unsatisfactory for a number of reasons. HAT has two stages. In stage 1 the parasites proliferate in the haemolymphatic system. In stage 2 they invade the central nervous system and brain provoking progressive neurological dysfunction leading to symptoms that include the disrupted sleep wake patterns that give HAT its more common name of sleeping sickness. Targeting drugs to the central nervous system offers many challenges. However, it is the cost of drug development for diseases like HAT, that afflict exclusively people of the world's poorest populations, that has been the principal barrier to new drug development and has led to them becoming neglected. Here we review drugs currently registered for HAT, and also discuss the few compounds progressing through clinical trials. Finally we report on new initiatives that might allow progress to be made in developing new and satisfactory drugs for this terrible disease.

Recent advances of high voltage AlGaN/GaN power HFETs (2009)

We review our recent advances of GaN-based high voltage power transistors. These are promising owing to low on-state resistance and high breakdown voltage taking advantages of superior material properties. However, there still remain a couple of technical issues to be solved for the GaN devices to replace the existing Si-based power devices. The most critical issue is to achieve normally-off operation which is strongly desired for the safety operation, however, it has been very difficult because of the built-in polarization electric field. Our new device called GIT (Gate Injection Transistor) utilizing conductivity modulation successfully achieves the normally-off operation keeping low on-state resistance. The fabricated GIT on a Si substrate exhibits threshold voltage of +1.0V. The obtained on-state resistance and off-state breakdown voltage were 2.6m&Omega;&bull;cm2 and 800V, respectively. Remaining technical issue is to further increase the breakdown voltage. So far, the reported highest off-state breakdown voltage of AlGaN/GaN HFETs has been 1900V. Overcoming these issues by a novel device structure, we have demonstrated the world highest breakdown voltages of 10400V using thick poly-crystalline AlN as a passivation film and Via-holes through sapphire which enable very efficient layout of the lateral HFET array avoiding any undesired breakdown of passivation films. Since conventional wet or dry etching cannot be used for chemically stable sapphire, high power pulsed laser is used to form the via-holes. The presented GaN power devices demonstrate that GaN is advantageous for high voltage power switching applications replacing currently used Si-based power MOSFETs and IGBTs.

Sensitization of Nd 3+ emission by Sm 2+ in CaF 2 and other fluorite-structure hosts (1986)

Trivalent chromium is an efficient sensitizer of Nd3+ in several oxide crystal hosts. Since Cr3+ cannot be incorporated into many other hosts with the proper crystal field magnitude for Nd3+ sensitization, alternative sensitizers would be highly desirable, particularly for fluoride crystals, which have low nonlinear refractive indices. Divalent samarium, which can be incorporated in a number of fluoride hosts, has strong broad absorption bands in the visible and UV, and its red luminescence often overlaps strong Nd absorption lines.
