Photonic crystal nanocavities with quantum well or quantum dot active material (2004)

We have investigated the miniaturization of photonic devices for ultimate photon localization, and have demonstrated two-dimensional photonic crystal nanolasers with two important quantum nanostructures-quantum wells (QWs) and quantum dots (QDs). Photonic crystal cavities with QW active material, are simple, but powerful nanolasers to produce intense laser output for signal processing. On the other hand, when located in a high-quality factor (Q) nanocavity, because QD(s) strongly couple with the intense optical field, QD photonic crystal cavities are expected to be good experimental setups to study cavity quantum electrodynamics, in addition to high speed and compact laser sources. Our photonic crystal nanolasers have shown as small thresholds as 0.12mW and 0.22mW for QD-photonic crystal lasers and QW-photonic crystal lasers, respectively, by proper cavity designs and nanofabrication. For QD-photonic crystal lasers, whispering gallery modes in square lattice were used together with coupled cavity designs and, for QW-photonic crystal lasers, quadrapole modes in triangular lattice with fractional edge dislocations were used to produce high-<i>Q</i> modes with small mode volume.
Paradoxical effects of elastase inhibitor guamerin on the tissue repair of two different wound models: sealed cutaneous and exposed tongue wounds (2004)

Innate elastase inhibitors are known to be putatively involved in the regulation of tissue inflammation by inhibiting polymorphonuclear leukocyte (PMN) derived proteinases. The aim of this study was to evaluate affects of leukocyte elastase suppression and PMN infiltration on wound healing in mouse by administering the recombinant elastase inhibitor guamerin (rEIG) in two different wound models; 1) impaired pin-punctured dorsal mucosa of anterior tongue wound, 60 mice, treated with saline containing rEIG that were fed ad libitum and 2) stable linear excisional cutaneous wound, 40 mice, covered with fibrin sealant containing rEIG. The progress of healing was analyzed by histological methods. The tongue wounds treated with rEIG became edematous around the pin-punctured tongue wound, and influx of inflammatory cells and PMN into the underlying stromal tissue were seen rapidly after wounding and peaked between 2-4 days. Whereas the control mice showed almost no wheal formation in the pin-punctured wound, a far lesser levels of PMN infiltration, and almost complete wound closure in 4 days. In the other model, the liner excisional cutaneous wound treated with fibrin sealant containing rEIG showed early wound constriction, lesser degree of inflammatory cells influx, and complete reepithelialization in 4-5 days, whereas the wound of control mice with the fibrin sealant alone showed contrary delayed reepithelialization, greater degree of inflammatory cell infiltration, and consequencial formation of greater granulation tissue at wound site. Taken together, these data suggest paradoxical effects of rEIG on the wound healing where in the wound exposed to infiltrating milieu of microorganisms in the oral cavity, the rEIG aggravates the wound healing by interfering with other innate defensive factors and extended greater flux of PMNs to inflamed wound site, while in the wound enclosed by fibrin, the rEIG accelerated wound healing by inhibiting the inflammation-generated proteases and the acute inflammatory reaction.
Towards understanding and fixing upstream merge induced conflicts in divergent forks (2020)

Divergent forks are a common practice in open-source software development to perform long-term, independent and diverging development on top of a popular source repository. However, keeping such divergent downstream forks in sync with the upstream source evolution poses engineering challenges in terms of frequent merge conflicts. In this paper, we conduct the first industrial case study of the implications of frequent merges from upstream and the resulting merge conflicts, in the context of Microsoft Edge development. The study consists of two parts. First, we describe the nature of merge conflicts that arise due to merges from upstream and classify them into textual conflicts, build breaks, and test failures. Second, we investigate the feasibility of automatically fixing a class of merge conflicts related to build breaks that consume a significant amount of developer time to root-cause and fix. Towards this end, we have implemented a tool MrgBldBrkFixer and evaluate it on three months of real Microsoft Edge Beta development data, and report encouraging results.
Superior Conductive Solid-like Electrolytes: Nanoconfining Liquids within the Hollow Structures (2015)

The growth and proliferation of lithium (Li) dendrites during cell recharge are currently unavoidable, which seriously hinders the development and application of rechargeable Li metal batteries. Solid electrolytes with robust mechanical modulus are regarded as a promising approach to overcome the dendrite problems. However, their room-temperature ionic conductivities are usually too low to reach the level required for normal battery operation. Here, a class of novel solid electrolytes with liquid-like room-temperature ionic conductivities (>1 mS cm(-1)) has been successfully synthesized by taking advantage of the unique nanoarchitectures of hollow silica (HS) spheres to confine liquid electrolytes in hollow space to afford high conductivities (2.5 mS cm(-1)). In a symmetric lithium/lithium cell, the solid-like electrolytes demonstrate a robust performance against the Li dendrite problem, preventing the cell from short circuiting at current densities ranging from 0.16 to 0.32 mA cm(-2) over an extended period of time. Moreover, the high flexibility and compatibility of HS nanoarchitectures, in principle, enables broad tunability to choose desired liquids for the fabrication of other kinds of solid-like electrolytes, such as those containing Na(+), Mg(2+), or Al(3+) as conductive media, providing a useful alternative strategy for the development of next generation rechargeable batteries.

Quercetin 3-O-β-glucoside is better absorbed than other quercetin forms and is not present in rat plasma (2000)

The effect of the nature of the sugar moiety on quercetin absorption has been investigated in rats. Four groups of rats received an experimental meal containing 20 mg of quercetin equivalents, supplied as quercetin, quercetin 3-O-beta-glucoside, quercetin 3-O-beta-rhamnoside or rutin. Four hours after the meal, the metabolites identified in hydrolysed plasma were identical in all groups (3'- and 4'-methylquercetin). However, the total concentration of metabolites was markedly different: 11.2+/-1.8, 2.5+/-2.0 and 33.2+/-3.5 microM for the quercetin, rutin, and quercetin 3-glucoside meals respectively. After quercetin 3-rhamnoside consumption, we failed to detect any metabolites in the plasma. These data suggest that the 3-O-glucosylation improves the absorption of quercetin in the small intestine, whereas the binding of a rhamnose to the aglycone markedly depresses it. Additional experiments have shown that the higher plasma levels measured after quercetin 3-glucoside meal compared to the quercetin meal were maintained throughout the 24-hour period following the meal. Using a multi-electrode coulometric detection, together with suitable chromatographic conditions, we were able to distinguish between the conjugated and the glycosylated forms. Thus, we clearly showed the absence of quercetin 3-O-beta-glucoside in the plasma from rats fed a diet containing this glucoside. This result suggests that quercetin 3-O-beta-glucoside is hydrolysed before or during its intestinal absorption.

Studies of OFDM signal for broadband optical access networks (2010)

Using orthogonal-frequency-division-multiplexing (OFDM) format for passive optical network (PON) is a subject of great interest for recent research works. OFDM signal has high spectral efficiency, high tolerance to the fiber chromatic dispersion and the high flexibility on both multiple services provisioning and dynamic bandwidth allocation. In this paper we study the use of OFDM signals for optical access networks, including carrier distributed PON, heterogeneous optical wired/wireless network and a 100 Gb/s OFDM-PON. We first quantify the performance of the OFDM signal when subjected to the noise produced by two different Rayleigh backscattering (RB) components that are present in the carrier-distributed PON. Then, based on these results, we also study the possibility of using OFDM for signal remodulation in a long-reach (LR)-PON. We propose carrier-distributed OFDM PONs using a dual-feeder fiber architecture and wavelength-shifting to mitigate the RB noise. Afterwards, we propose heterogeneous optical wired/wireless access networks, combining 10 Gb/s PON and 10 Gb/s OFDM radio-over-fiber (ROF) network. Finally, we propose a 100 Gb/s OFDM-PON using subcarrier multiplexing (SCM).
Electrostatic Sprays of Food‐Grade Acids and Plant Extracts are More Effective than Conventional Sprays in Decontaminating Salmonella Typhimurium on Spinach (2010)

About 40000 people fall victim to Salmonella infections every year in the United States. Recent occurrences of Salmonella contaminated spinach and its recalls have accelerated the need for efficient antimicrobials targeting these pathogens. Our study was aimed at evaluating the inhibitory properties of malic, tartaric, and lactic acids, and grape seed extract (GSE) alone and in combinations and their application methods against Salmonella Typhimurium-inoculated spinach using a response surface method. Fresh spinach leaves were washed, disinfected with sodium hypochlorite solution (0.04% v/v), rewashed with sterile deionized (DI) water, and inoculated with a 2nd-day culture of S. Typhimurium (7.0 log CFU/mL). Adhered S. Typhimurium population on day 0 were 7.5 log CFU/g. These were treated with individual and combinations of organic acids with GSE or DI water (control) adjusted to the same pH as that of the test solutions with both the modes of application and leaves were refrigerated at 4 °C. Malic acid (2%) in combination with GSE (3%) or lactic acid (3%) sprayed electrostatically showed reductions of 2.6 to 3.3 log CFU/g compared to lower log reductions (0.0 to 0.3 log CFU/g) by day 14 if sprayed conventionally. These findings indicate that malic acid in combination with GSE/lactic acid solutions applied by electrostatic spraying exhibited higher inhibition of pathogens than conventional spraying and can be used for commercial applications to enhance food safety.
Control System Design on a Power-Split CVT for High-Power Agricultural Tractors (2004)

The problem considered in this paper is the design and tuning of the control system of a power-split continuously variable transmission (CVT) used in high-power tractors. Power-split CVTs are characterized by the combination of a traditional mechanical transmission and by a continuously-variable transmission. This guarantees, at the same time, smooth variations of the transmission-ratio and high efficiency of the overall transmission system. The control architecture of an hydrostatic power-split CVT is constituted by three main parts: 1) servo-controller on the current of the valve which drives the hydraulic transmission; 2) a servo-controller on the hydraulic transmission-ratio; and 3) a synchronizer which coordinates the hydraulic and the mechanical parts of the CVT. In this work, these three controllers are fully developed, including: design, implementation, and evaluation on an experimental system.

Research on the Performance of a Waterjet Propulsor for Personal Watercrafts (1999)

&lt;div class="htmlview paragraph"&gt;A waterjet propulsor has come to be used more popularly for high speed watercrafts such as personal watercrafts. The most difficult problem for designing the waterjet system is that a tradeoff is required to properly determine the best parameters for the waterjet pump and subsequently the best overall propulsion system. This paper presents the design method and performance improvement of the waterjet propulsor used for personal watercrafts. The authors have clarified the performance of the individual component in the waterjet propulsor and improved the component efficiency empirically, and established the method to estimate the thrust and power characteristics of the propulsor on board from the component test results and other design parameters, which enables the optimization of the waterjet system.&lt;/div&gt;
First optical design for wide angle micro LED without second lens (2020)

This study proposed 1st optical design for wide angle micro LED without 2nd lens. Micro LEDs are point light sources that the beam angle of 120&deg;, therefore, a large number of LEDs are needed to achieve a uniform area light source. We used 1st optical design to modulate luminous intensity curve, in which micro LED as chip and through chip scale packaging (CSP) process to design wide angle micro LED that achieve full width at half maximum (FWHM) of 180&deg;. The prototype used a square packaged that with a flip chip. Chip length, width and height of 240um, 130um and 80um respectively, the structure of wide angle micro-LEDs is including flip chip as light source, side wall around chip, a light guide layer, and a diffusion layer. The light guide layer has a great correlation with the light extraction efficiency, the diffusion layer used to control the ratio of the transmittance and reflectivity rate. We analyze the thickness of light guide layer and diffuser layer from 0.1mm to 0.4mm and 0.1mm to 0.3mm, respectively. In which the optimized package structure of thickness of light guide layer of 0.4mm, thickness of diffusion layer of 0.2mm. The prototype shows that light extraction rate of 95%, central light intensity of 25.6%, peak angle at 66&deg; and full width at half maximum (FWHM) of 180&deg;. This design proposed for thin, flexible, and uniform surface light source.
Matrigel coatings forParylene sheath neural probes (2015)

The biologically derived hydrogel Matrigel (MG) was used to coat a Parylene-based sheath intracortical electrode to act as a mechanical and biological buffer as well as a matrix for delivering bioactive molecules to modulate the cellular response and improve recording quality. MG was loaded with dexamethasone to reduce the immune response together with nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF) to maintain neuronal density and encourage neuronal ingrowth toward electrodes within the sheath. Coating the Parylene sheath electrode with the loaded MG significantly improved the signal-to-noise ratio for neural events recorded from the motor cortex in rat for more than 3 months. Electron microscopy showed even coverage of both the Parylene substrate and the platinum recording electrodes. Electrochemical impedance spectroscopy (EIS) of coated electrodes in 1× phosphate-buffered saline demonstrated low impedance required for recording neural signals. This result was confirmed by in vivo EIS data, showing significantly decreased impedance during the first week of recording. Dexamethasone, NGF, and BDNF loaded into MG were released within 1 day in 1× phosphate-buffered saline. Although previous studies showed that MG loaded with either the immunosuppressant or the neurotrophic factor cocktail provided modest improvement in recording quality in a 1-month in vivo study, the combination of these bioactive molecules did not improve the signal quality over coating probes with only MG in a 3-month in vivo study. The MG coating may further improve recording quality by optimizing the in vivo release profile for the bioactive molecules.
The HoloLens Augmented Reality System Provides Valid Measures of Gait Performance in Healthy Adults (2020)

Biomechanical measures are the gold standard in the assessment of gait in healthy and chronic disease populations. Augmented reality (AR) systems represent an opportunity to evaluate human movement under more realistic and interactive conditions. A barrier to integrating AR into healthcare is the unknown accuracy of systems in the quantification of human movement. This project aimed to determine the accuracy of the HoloLens relative to three-dimensional motion capture (MoCap) in quantifying gait. Ten healthy adults completed nine walking trials (n = 3 for slow, medium, and fast speed, respectively). Outcome measures included: cumulative walking distance, number of steps, step length, and speed. Statistical equivalence testing, using an a priori threshold of five percent, confirmed biomechanical measures derived from the HoloLens was equivalent to MoCap. Cumulative walking distance from the HoloLens was within 1.5-2.1% of the MoCap system for all walking speeds. Difference between systems in terms of movement accuracy was less than 3.7 cm across trials. Equivalence in outcomes makes the HoloLens appropriate for the quantification of frequently used gait variables to characterize walking performance. Future AR applications have the potential to deliver digital therapeutics to patient populations under more real-world conditions and monitor performance using objective and quantitative outcomes.

Effect of Transforming Growth Factor-β1on Proliferation and Death of Rat Prostatic Cells* (1990)

The ability of transforming growth factor B1 (TGF beta 1) to inhibit proliferation and activate death of rat ventral prostatic glandular cells was tested both in vivo and in vitro. In vivo administration of 50 ng TGF beta 1/day directly to the regressed ventral prostate of previously castrated male rats had no effect on the proliferative regrowth of the prostatic glandular cells induced by exogeneous androgen replacement. In addition, androgen-stimulated ventral prostatic cell proliferation in vitro in organ culture was not affected by exposure to 0.1-20 ng/ml TGF beta 1. In contrast in vivo administration of 50 ng TGF beta 1/day directly to the ventral prostate of intact noncastrated male rats resulted in the death of about 25% of the prostatic glandular cells within 7 days of treatment. Such TGF beta 1 treatment did not lower serum testosterone, nor did it affect the size or DNA content of the seminal vesicles, demonstrating the local nature of the response. Likewise, in androgen-maintained ventral prostate organ cultures in vitro, there was a dose-response relationship between glandular cell death and TGF beta 1 concentration in the medium. These results demonstrate that TGF beta 1 can induce the death of androgen-dependent prostatic glandular cells even when physiological levels of androgen are present. Previous studies have demonstrated that both the receptor and the mRNA for TGF beta 1 increase rapidly in the ventral prostate after castration. Taken with the present data, these results suggest that TGF beta 1 may be a physiological intermediate in the programmed cell death of rat prostatic glandular cells activated after androgen ablation.
Al-2.28 Defect-Free Pattern (2021)

As increasingly smaller molecular materials and material structures are devised or developed for technological applications, the demands on the processes of lithography now routinely include feature sizes that are of the order of 10 nm. In reaching such a fine level of resolution, the methods of lithography have increased markedly in sophistication and brought into play 2terminology that is unfamiliar, on the one hand, to scientists tasked with the development of new lithographic materials or, on the other, to the engineers who design and operate the complex equipment that is required in modern-day processing. Publications produced by scientists need to be understood by engineers and vice versa, and these commonly arise from collaborative research that draws heavily on the terminology of two or more of the traditional disciplines. It is developments in polymer science and material science that lead progress in areas that cross traditional boundaries, such as microlithography. This document provides the exact definitions of a selection of unfamiliar terms that researchers and practitioners from different disciplines might encounter.
A concurrent multi-band power amplifier with compact matching networks (2011)

This paper presents a novel configuration for a concurrent multi-band power amplifier (PA). A multi-band matching network comprises a multi-section impedance transformer that achieves matching in multiple bands. The proposed impedance transformer provides flexibility in the design of a concurrent multi-band PA in a wide frequency range. The impedance transformer is compact since each section comprises a combination of a T-shaped network, a shunt tank circuit, and a matching element. The proposed 1W-class dual-band PA achieves a maximum power added efficiency of greater than 53% at 0.8 GHz and 3.3 GHz.
