Software-defined network support for transport resilience (2014)

Existing methods for traffic resilience at the network and transport layers typically work in isolation, often resorting to inference in fault detection and recovery respectively. This both duplicates functionality across layers, eroding efficiency, and leads to protracted recovery cycles, affecting responsiveness. Such misalignment is particularly at odds with the unprecedented concentration of traffic in data-centers, in which network and hosts are managed in unison. This paper advocates instead a cross-layer approach to traffic resilience. The proposed architecture, INFLEX, builds on the abstractions provided by software-defined networking (SDN) to maintain multiple virtual forwarding planes which the network assigns to flows. In case of path failure, transport protocols pro-actively request to switch plane in a manner which is unilaterally deployable by an edge domain, providing scalable end-to-end forwarding path resilience.
Control of hybrid dynamical systems for electric vehicles (2001)

This paper presents a system controller for hybrid electric vehicles using hybrid dynamical system theory. The hierarchical control structure of parallel hybrid electric vehicle systems is first introduced and the drive control problem of the vehicle is formulated using the hybrid dynamical system theory. The controller design problem and the optimal control of the vehicle system is investigated and an optimal coordination strategy is developed based on the minimization of the system cost subject to system constraints, where the optimal solution is obtained by solving a sequential quadratic programming problem. The simulation is conducted with a comparison study between the optimal control strategy and a rule-based control strategy.
A reduced order model for an electrified vehicle and application to vibration suppression control (2013)

A method to give a prospect of controller design for a vibration suppression control of driving force of a plug-in hybrid electric vehicle is proposed. This method is applicable to design a controller mathematically and systematically by applying a concept of a reduced order plant model and using a computer algebra system. Furthermore, based on this method, a new concept of vibration suppression control of a multiple driving sources system is proposed by extending a conventional concept of a single input system. The proposed concept enables driving force of a multiple driving sources system to suppress vibration of drive shafts and the vehicle pitch.

A Simple Photocell To Demonstrate Solar Energy Using Benign Household Ingredients (2013)

A laboratory exercise for the construction of a dye-sensitized solar cell using everyday household and benign products has been developed. The simple and easy-to-assemble construction successfully demonstrates the conversion of solar energy to electrical energy. This project is intended for high school students as well as college students of chemistry, physics, or biology classes as an inexpensive hands-on exercise. A brief outline on basic measurements related to photovoltaic cell performance and its characterization is also presented, and approaches to use these concepts for demonstration are suggested.
Construction of Robust Ruthenium(salen)(CO) Complexes and Asymmetric Aziridination with Nitrene Precursors in the Form of Azide Compounds That Bear Easily Removable <i>N</i>‐Sulfonyl Groups (2007)

We synthesized new Ru(salen)(CO) complexes of high durability and achieved aziridination with good to excellent enantioselectivity by using azide compounds that contain an easily removable N-sulfonyl group, such as the 2-(trimethylsilyl)ethanesulfonyl group, as a nitrene precursor. Aziridination of less-reactive alpha,beta-unsaturated esters (and amides) proceeded with excellent enantioselectivities, from which it is inferred that an electrophilic species is the active species of this reaction. The present asymmetric aziridination provides a useful tool for introducing optically active nonprotected amine groups.
One proven methodology for designing robust online help systems (1993)

Anonline help system is robust when it anticipates the user's behavior, offers swift access to the right information, and is user intuitive. As with all good userd ocumentation, an online help system requires you to devote significant effort to design. However, because an online help system is integral to the software it supports, it also rquiresa number of up front decisions about how it will be implemented.
Synthesis of multicomponent sulfide Ag<sub>2</sub>ZnSnS<sub>4</sub>as an efficient photocatalyst for H<sub>2</sub>production under visible light irradiation (2012)

Stannite-type multicomponent sulfide (Ag2ZnSnS4) nanoparticles with particle diameters of 100–200 nm were synthesized through a solvothermal treatment combined with a post-annealing process under N2 atmosphere. The obtained Ag2ZnSnS4 was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), high-resolution transmission electron microscopy (HRTEM), UV-vis diffuse reflectance spectroscopy (DRS) and X-ray photoelectron spectroscopy (XPS). The photocatalytic activities for hydrogen production of Ag2ZnSnS4 were evaluated under visible light (λ ≥ 420 nm) irradiation. It was found that the 1.0 wt% Pt-loaded Ag2ZnSnS4 displayed a photocatalytic hydrogen evolution activity of 580 μmol h−1 with a fairly good apparent quantum efficiency of 15.2% at 420 nm incident light irradiation.
Design Space Exploration of Microring Resonators in Silicon Photonic Interconnects: Impact of the Ring Curvature (2018)

A detailed analysis of fundamental tradeoffs between ring radius and coupling gap size is presented to draw realistic borders of the possible design space for microring resonators (MRRs). The coupling coefficient for the ring-waveguide structure is estimated based on an integration of the nonuniform gap between the ring and the waveguide. Combined with the supermode analysis of two coupled waveguides, this approach is further expanded into a closed-form equation that describes the coupling strength. This equation permits to evaluate how the distance separating a waveguide from a ring resonator, and the ring radius, affect coupling. The effect of ring radius on the bending loss of the ring is furthermore modeled based on the measurements for silicon MRRs with different radii. These compact models for coupling and loss are subsequently used to derive the main optical properties of MRRs, such as 3-dB optical bandwidth, extinction ratio of resonance, and insertion loss, hence identifying the design space. Our results indicate that the design space for add-drop filters in a wavelength division multiplexed link is currently limited to 5-10 μm in radius and gap sizes ranging from 120 to 210 nm. The good agreement between the results from the proposed compact model for coupling and the numerical FDTD and experimental measurements indicate the application of our approach in realizing fast and efficient design space exploration of MRRs in silicon photonic interconnects.

Cocaine Disrupts Estrous Cyclicity and Alters the Reproductive Neuroendocrine Axis in the Rat (1990)

Although a common drug of abuse, cocaine’s effects on cyclic reproductive functions and the neuroendocrine systems regulating these functions have not been studied. Here, we report the effects of cocaine on (1) estrous cyclicity and ovulation rates and (2) the stimulated in vitro release of hypothalamic GnRH and aminergic neurotransmitters directly involved in regulating or modulating GnRH release. Within 7 days of treatment with 10 mg kg–1 day–1 of cocaine HC1 subcutaneously, rats demonstrated significant estrous cycle irregularity including repetitive days of estrus and prolonged periods of diestrus. After 6 weeks of treatment, cocaine-treated rats exhibited a 44.3% decrease in ovulation rates. For the in vitro studies, bilaterally ovariectomized rats were injected with cocaine (10 mg kg–1 day–1) or with saline for 2 weeks. Each rat received estradiol benzoate (50 mg kg–1 day–1 s.c.) for 2 days before sacrifice. Hypothalamic slices were prepared, placed in 0.1 ml microchambers and perfused with modified Krebs buffer (pH 7.4) using a programmable perfusion system. Basal release of norepinephrine (NE) and serotonin (5HT) was significantly increased in the cocaine-treated group versus controls. Ten-minute pulses of 10–7M progesterone (P4) increase NE and 5HT, but not dopamine (DA), release in the saline-treated group. In contrast, pulses of P4 increased NE, but not 5HT or DA, in the cocaine-treated rats. Ten-minute pulses of 0.1 µM NE increased GnRH release in both saline- and cocaine-treated rats. However, the response to pulsed NE was significantly attenuated in the cocaine-treated group. The results of this study demonstrate that cocaine disrupts estrous cyclicity by altering the hypothalamic amine activity necessary for pulsatile hypothalamic GnRH release. However, a direct effect of cocaine on the pituitary gland or ovaries cannot be excluded on the basis of these results.
Versatile wireless sacrificial transducers for electronic structural surveillance sensors (2009)

The goal of this work is to develop novel transducers for use with our low-cost unpowered wireless Electronic Structural Surveillance (ESS) sensors aimed at monitoring corrosion of the steel reinforcement in concrete. A new transduction scheme is presented which incorporates a fully exposed sacrificial transducer element capable of non-contact interaction with the sensor circuitry. This wire-free interaction of the fully exposed, sacrificial transduction layer is the key innovation avoiding the need to breach the hermetic seal that protects the sensing circuit and yet maintain direct monitoring of corrosion. This design also allows the transducer to make use of a variety of materials and morphologies. Here we present our new design, experimentally demonstrate the behavior of our prototype sensor, and develop a new paradigm for transduction in passive wireless sensors.

Myocardial Extraction of Labeled Long-Chain Fatty Acid Analogs (1975)

The single circulation myocardial extraction of terminally iodinated hexadecenoic acid (77 plus or minus 11.0%) is approximately two times the extraction of 18 carbon fatty acids (33 plus or minus 5.2%) prepared by iodination of double bonds. The results compare favorably with natural 28 carbon steraic (70 plus or minus 7.5%) and oleic (61 plus or minus 7.8%) acids labeled with carbon-11 in the carboxyl group. It is concluded that terminally radioiodinated long chain fatty acids can be used as substitues for in vivo investigations of fatty acid distribution and in particular may be useful as a regional mycardial blood flow indicator.
Twenty-Four-Hour Esophageal Impedance-pH Monitoring in Healthy Preterm Neonates: Rate and Characteristics of Acid, Weakly Acidic, and Weakly Alkaline Gastroesophageal Reflux (2006)

We present the first study using 24-hour impedance-pH recordings in asymptomatic premature neonates. Previous studies that used pH-metry suggested that neonatal cardiorespiratory symptoms could be related to acid gastroesophageal reflux. However, pH-metry could not detect accurately weakly acidic or nonacid reflux. Our healthy premature neonates had approximately 70 reflux events in 24 hours, 25% of which were acid, 73% were weakly acidic, and 2% were weakly alkaline. The number of reflux events per hour (2-3 per hour) was slightly lower than that described in premature neonates with cardiorespiratory events (4 per hour). We confirmed that weakly acidic reflux is more prevalent than acid reflux, particularly so during the feeding periods. In contrast, similar to healthy adults, weakly alkaline reflux was very rare. We confirmed findings from previous studies in which most reflux events were pure liquid during both fasting and during postprandial periods and gas reflux was very rare. As in neonates with cardiorespiratory symptoms, the majority of reflux events in asymptomatic preterms reached the proximal esophagus or pharynx, and there were no differences between acid and weakly acidic reflux. The lack of differences between asymptomatic and diseased infants contravenes the hypothesis for macro- or microaspiration but does not exclude hypersensitivity to reflux as a cause for respiratory symptoms. The acid exposure that was related to reflux events and detected by impedance was significantly lower than the total acid exposure during 24 hours. Increased acid exposure could be attributable to pH-only reflux events or, less frequently, to slow drifts of pH from baselines at approximately 5 to values < 4. These changes were not accompanied by a typical impedance pattern of reflux but by slow drifts in impedance in 1 or 2 channels. Our findings confirm the need for the use of impedance together with pH-metry for diagnosis of all gastroesophageal reflux events. The relationship between gastroesophageal reflux and cardiorespiratory events in neonates and older infants has been studied extensively. The current evidence for such a relationship is controversial. This study provides values of impedance-pH monitoring for acid, weakly acidic, and weakly alkaline reflux from healthy preterm neonates that can be used for comparison when evaluating gastroesophageal reflux in preterm infants with a cardiorespiratory disease.
Framework and algorithms for network bucket testing (2012)

Bucket testing, also known as split testing, A/B testing, or 0/1 testing, is a widely used method for evaluating users' satisfaction with new features, products, or services. In order not to expose the whole user base to the new service, the mean user satisfaction rate is estimated by exposing the service only to a few uniformly chosen random users. In a recent work, Backstrom and Kleinberg, defined the notion of network bucket testing for social services. In this context, users' interactions are only valid for measurement if some minimal number of their friends are also given the service. The goal is to estimate the mean user satisfaction rate while providing the service to the least number of users. This constraint makes uniform sampling, which is optimal for the traditional case, grossly inefficient. In this paper we introduce a simple general framework for designing and evaluating sampling techniques for network bucket testing. The framework is constructed in a way that sampling algorithms are only required to generate sets of users to which the service should be provided. Given an algorithm, the framework produces an unbiased user satisfaction rate estimator and a corresponding variance bound for any network and any user satisfaction function. Furthermore, we present several simple sampling algorithms that are evaluated using both synthetic and real social networks. Our experiments corroborate the theoretical results and demonstrate the effectiveness of the proposed framework and algorithms.
CS-600 a new anti-inflammatory agent III Stereospecific formation of an active metabolite by ketone reductase (1983)

Gastrointestinal absorption of CS-600 was shown to be rapid and almost quantitative in rats. The cyclopentanone moiety of CS-600 was reduced rapidly to afford a mixture of trans-OH and cis-OH as principal metabolites in plasma of rats, dogs and monkeys. The plasma levels of trans-OH having strong inhibitory activity for PG synthetases was 2-3 times higher than that of cis-OH. The stereochemistry of trans-OH isolated from rat urine was established to be a single SRS-configuration, indicating the stereospecific reduction of the cyclopentanone moiety. The CS-600 reducing enzyme was purified from rabbit liver cytosol fraction as single protein and shown to be one of the aromatic aldehyde-ketone reductases on the basis of substrate specificity, effects of inhibitors, optimal pH (6.2), cofactor requirement (NADPH) and molecular weight (ca. 33, 000) .
Design and fabrication of MEMS logic gates (2008)

This paper presents a novel design of MEMS logic gate that can perform Boolean algebra the same as logic devices that are composed of solid-state transistors. This MEMS logic gate design inherits all the advantages from MEMS switches and thus is expected to have more applications than MEMS switches. One unique feature of this device is that it can perform either NAND gate or NOR gate functions with the same mechanical structure but with different electrical interconnects. In a prototype design, the device is 250 µm long, 100 µm wide and has 1 µm gap. The experimental results show that this device can operate at 10/0 V and achieve the proposed logic functions. The resonant frequency of the device is measured roughly at 30 kHz. Due to no metal-to-metal contact in the current device, the logic functions of the design are verified through observations and video taping.
Towards user-oriented RBAC model (2015)

Role mining is to define a role set to implement the role-based access control (RBAC) system and regarded as one of the most important and costliest implementation phases. While various role mining models have been proposed, we find that user experience/perception – one ultimate goal for any information system – is surprisingly ignored by the existing works. One advantage of RBAC is to support multiple role assignments and allow a user to activate the necessary role to perform the tasks at each session. However, frequent role activating and deactivating can be a tendinous thing from the user perspective. A user-friendly RBAC system is expected to assign few roles to every user. So in this paper we propose to incorporate to the role mining process a user-role assignment constraint that mandates the maximum number of roles each user can have. Under this rationale, we formulate user-oriented role mining as the user role mining problem, where all users have the same maximal role assignments, the personalized role mining problem, where users can have different maximal role assignments, and the approximate versions of the two problems, which tolerate a certain amount of deviation from the complete reconstruction. The extra constraint on the maximal role assignments poses a great challenge to role mining, which in general is already a hard problem. We examine some typical existing role mining methods to see their applicability to our problems. In light of their insufficiency, we present a new algorithm, which is based on a novel dynamic candidate role generation strategy, tailored to our problems. Experiments on benchmark data sets demonstrate the effectiveness of our proposed algorithm.

Thrombin and inflammatory proteins are elevated in Alzheimer's disease microvessels: Implications for disease pathogenesis (2006)

The notion that microvascular abnormalities contribute to deleterious changes in the Alzheimer's disease (AD) brain is supported by work from our laboratory and others demonstrating biochemical and functional alterations of the microcirculation in AD. The objective of this study is to determine whether levels of neurotoxic (thrombin) and inflammatory (interleukin 8 (IL-8), integrins alphaVbeta3 and alphaVbeta5) proteins are altered in microvessels isolated from AD patients compared to levels in vessels obtained from non-demented age-matched controls. We also evaluate in AD and control microvessels expression of the transcription factor hypoxia-inducible factor 1-alpha(HIF1-alpha), which regulates pro-inflammatory gene expression, and the regulation of HIF1-alpha expression by thrombin in cultured brain endothelial cells. Our results indicate that in AD there are high levels of expression of the neurotoxic protease thrombin and the inflammation-associated proteins IL-8 and alphaVbeta3 and alphaVbeta5 integrins. HIF1-alpha is higher in AD microvessels compared to control and thrombin treatment of cultured brain endothelial cells results in increased expression of HIF1-alpha. These data suggest that in AD the cerebral microcirculation is a source of neurotoxic and inflammatory mediators and as such contributory to pathologic processes ongoing in the AD brain.
