Tunable Electrical and Optical Characteristics in Monolayer Graphene and Few-Layer MoS<sub>2</sub> Heterostructure Devices (2015)

Lateral and vertical two-dimensional heterostructure devices, in particular graphene-MoS2, have attracted profound interest as they offer additional functionalities over normal two-dimensional devices. Here, we have carried out electrical and optical characterization of graphene-MoS2 heterostructure. The few-layer MoS2 devices with metal electrode at one end and monolayer graphene electrode at the other end show nonlinearity in drain current with drain voltage sweep due to asymmetrical Schottky barrier height at the contacts and can be modulated with an external gate field. The doping effect of MoS2 on graphene was observed as double Dirac points in the transfer characteristics of the graphene field-effect transistor (FET) with a few-layer MoS2 overlapping the middle part of the channel, whereas the underlapping of graphene have negligible effect on MoS2 FET characteristics, which showed typical n-type behavior. The heterostructure also exhibits a strongest optical response for 520 nm wavelength, which decreases with higher wavelengths. Another distinct feature observed in the heterostructure is the peak in the photocurrent around zero gate voltage. This peak is distinguished from conventional MoS2 FETs, which show a continuous increase in photocurrent with back-gate voltage. These results offer significant insight and further enhance the understanding of the graphene-MoS2 heterostructure.
Feed circuits of double-layered self-diplexing antenna for mobile satellite communications (1992)

An analysis of feed circuits for a double-layered self-diplexing antenna for mobile satellite communications is presented. It is possible to reduce the weight of the diplexer for a self-diplexing antenna by getting large internal isolation between transmitting and receiving. The internal isolation is shown to be heavily dependent on the configuration and errors of the feed circuits of the antenna. The feed circuits of two- and four-point feeds for the antenna are discussed, using the cavity model of microstrip elements, and an error analysis of the feed circuit is carried out.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
The role of nitric oxide in arthritic joints: a therapeutic target? (2000)

Nitric oxide (NO) is produced by many cell types in the joint, and its expression is delicately regulated. Depending on its concentration and cellular origin, NO appears to have both pro- and anti-inflammatory potential in the joint. Constitutively expressed nitric oxide synthase (NOS) produces small amounts of NO, which is essential for normal physiological homeostasis. However, inflammatory stimuli such as endotoxins, cytokines, and growth factors promote inducible NOS (iNOS) expression, initially as an anti-inflammatory response, and catalyse a high output of NO. Excessive NO can amplify inflammatory pathways and contribute to the development and maintenance of arthritis. Consequently, proper regulation of NO synthesis can lead to a novel therapeutic approach for inflammatory joint diseases. Further careful study will be necessary to develop new drugs to regulate the NO pathway and to determine the dosage, timing of administration, and duration of treatment in order to avoid both undesirable immunostimulatory effects and immunosuppressive effects.
The effect of various concentrations of tocopherols and tocopherol mixtures on the oxidative stability of a sample of lard (1968)

Abstract A comparison was made of α‐, γ‐, and δ‐tocopherol at various concentrations and a mixture of these tocopherols representing the average tocopherol content of peanut oil on the oxidative stability of lard at 97C. Uptake of oxygen was used to indicate the length of the induction period. The antioxidant effectiveness of the tocopherols was found to increase in the order α, δ, γ. The antioxidant efficiency decreases with increasing concentrations of tocopherols such that addition of any single tocopherol above a concentration of 250 µg/g has little effect on oxidative stability. A mixture equivalent to that of an average peanut oil sample, containing 150 µg/g of α‐tocopherol and 250 µg/g of γ‐tocopherol and 15 µg/g of δ‐tocopherol was found to be no more stable than one containing 250 µg/g of γ‐tocopherol alone.
An approach to benchmarking configuration complexity (2004)

Configuration is the process whereby components are assembled or adjusted to produce a functional system that operates at a specified level of performance. Today, the complexity of configuration is a major impediment to deploying and managing computer systems. We describe an approach to quantifying configuration complexity, with the ultimate goal of producing a configuration complexity benchmark. Our belief is that such a benchmark can drive progress towards self-configuring systems. Unlike traditional workload-based performance benchmarks, our approach is process-based. It generates metrics that reflect the level of human involvement in the configuration process, quantified by interaction time and probability of successful configuration. It computes the metrics using a model of a standardized human operator, calibrated in advance by a user study that measures operator behavior on a set of parameterized canonical configuration actions. The model captures the human component of configuration complexity at low cost and provides representativeness and reproducibility.
Pulse control of D-C and A-C motors by silicon-controlled rectifiers (1964)

Because of its short turn-off time, the silicon-controlled rectifier (SCR) can be turned off by means of capacitor discharge pulses and, therefore, it can be used not only to switch on heavy currents, but also to switch them off. This holds true for high operating frequencies as well as for an almost unlimited number of switching duties. As a result, the possibility arises of a pulse technique with new methods of both contactless and continuous speed control of d-c and a-c motors; this technique, in turn, presents new possibilities for the inverter-type speed control of 3-phase motors.
QTL dynamics for fruit firmness and softening around an ethylene-dependent polygalacturonase gene in apple (Malusxdomestica Borkh.) (2010)

Apple fruit are well known for their storage life, although a wide range of flesh softening occurs among cultivars. Loss of firmness is genetically coordinated by the action of several cell wall enzymes, including polygalacturonase (PG) which depolymerizes cell wall pectin. By the analysis of 'Fuji' (Fj) and 'Mondial Gala' (MG), two apple cultivars characterized by a distinctive ripening behaviour, the involvement of Md-PG1 in the fruit softening process was confirmed to be ethylene dependent by its transcript being down-regulated by 1-methylcyclopropene treatment in MG and in the low ethylene-producing cultivar Fj. Comparing the PG sequence of MG and Fj, a single nucleotide polymorphism (SNP) was discovered. Segregation of the Md-PG1(SNP) marker within a full-sib population, obtained by crossing Fj and MG, positioned Md-PG1 in the linkage group 10 of MG, co-located with a quantitative trait locus (QTL) identified for fruit firmness in post-harvest ripening. Fruit firmness and softening analysed in different stages, from harvest to post-storage, determined a shift of the QTL from the top of this linkage group to the bottom, where Md-ACO1, a gene involved in ethylene biosynthesis in apple, is mapped. This PG-ethylene-related gene has beeen positioned in the apple genome on chromosome 10, which contains several QTLs controlling fruit firmness and softening, and the interplay among the allelotypes of the linked loci should be considered in the design of a marker-assisted selection breeding scheme for apple texture.
Vaudevival: Old is the new New (2012)

Vaudevival: Old is the new New was an evening-length concert performed October 20th & 21st, 2011 at the Clarice Smith Performing Arts Center in partial fulfillment of the M.F.A. degree in Dance from the University of Maryland's School of Theatre, Dance, and Performance Studies. Vaudevival was a "trad" dance theater project that challenged concepts of aesthetic hierarchies in popular culture. The show ricocheted through twentieth-century vernacular dance to create a vibrant statement about the cyclical nature of art and society, with live music and multi-media projections. This paper is a written account of theoretical and practical problems of identity politics and appropriation that unfolded during the choreographic process. Envisioning a creative utopia free of exploitative hierarchies - both on the stage and on the page, Vaudevival invokes the old to reinvent the new through the intertextuality of American dances, bringing scholarship to the theater, and bringing some theater to scholarship.
Survival of patients with hereditary colorectal cancer: Comparison of HNPCC and colorectal cancer in FAP patients with sporadic colorectal cancer (1999)

Conflicting data exist on the prognosis of hereditary colorectal cancer. HNPCC patients, in particular, are often reported to have a better survival. We examined 2,340 colorectal-cancer patients treated in our Institution: 144 HNPCC patients (Amsterdam Criteria), 161 FAP patients and 2,035 patients with sporadic cancer. Data on hereditary-cancer patients treated between 1980 and 1995 was collected in a registry. The 2,035 sporadic colorectal-cancer patients (controls) included all new cases treated in the Department of Gastrointestinal-Tract Surgery during the same period. Observed survival was estimated using the Kaplan-Meier method. Cumulative survival probability was estimated at 5 years within each group and stratified by various clinical and pathological variables. The age distribution at diagnosis of sporadic patients was significantly higher than that of FAP and HNPCC patients (median 60 years vs. 43 and 49 years; p < 0.0001). In the HNPCC group, 40% had a right cancer location, vs. 14% in the FAP group and 13% in the sporadic-cancer group. In the sporadic group, 51% were early-stage cancers (Dukes A or B) vs. 48.4% and 52.1% in the FAP and HNPCC groups respectively. In the HNPCC, FAP and sporadic-cancer groups, the 5-year cumulative survival rate was 56.9%, 54.4% and 50.6% respectively. Survival analysis by the Cox proportional-hazards method revealed no substantial survival advantage for HNPCC and FAP patients compared with the sporadic group, after adjustment for age, gender, stage and tumor location. The hazard ratio for HNPCC was 1.01 (95% CI 0.72-1.39) and 1.27 (95% CI 0.95-1.7) for FAP patients compared with the sporadic-colorectal-cancer group.
New phosphorylation procedure. Activation of phosphates with cyclohexyl isocyanide (1974)

Cyclohexyl isocyanide reacts with nucleoside 2′(3′)-phosphates to afford 2′,3′-cyclic phosphates or with a mixture of phosphomonoesters (viz., 2′,3′-di-O-acetyluridine 5′-phosphate or phenyl phosphate) and alcohols to give the corresponding phosphodiesters in ca. 90% yields.
Low-temperature bonding of laser diode chips on Si substrates with oxygen and hydrogen atmospheric-pressure plasma activation (2009)

Surface activated bonding (SAB) method with atmospheric-pressure plasma treatment is an effective approach to develop low cost, low damage, and low temperature bonding technology. In this research, not only conventional low-pressure plasma treatment (Ar RF plasma) but also atmospheric-pressure plasma treatment (Ar+O <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> , Ar+H <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> ) was investigated for low-temperature Au-Au surface-activated bonding (150degC).

Bacterial Endosymbionts of Free‐living Amoebae<sup>1</sup> (2004)

The occurrence of bacterial endosymbionts in free-living amoebae has been known for decades, but their obligate intracellular lifestyle hampered their identification. Application of the full cycle rRNA approach, including 16S rRNA gene sequencing and fluorescence in-situ hybridization with 16S rRNA-targeted oligonucleotide probes, assigned the symbionts of Acanthamoeba spp. and Hartmannella sp. to five different evolutionary lineages within the Proteobacteria, the Bacteroidetes, and the Chlamydiae, respectively. Some of these bacterial symbionts are most closely related to bacterial pathogens of humans, and it has been suggested that they should be considered potential emerging pathogens. Complete genome sequence analysis of a chlamydia-related symbiont of Acanthamoeba sp. showed that this endosymbiont uses similar mechanisms for interaction with its eukaryotic host cell as do the well-known bacterial pathogens of humans. Furthermore, phylogenetic analysis suggested that these mechanisms have been evolved by the ancestor of these amoeba symbionts in interplay with ancient unicellular eukaryotes.
Development of Models for Managing Network Congestion on Global System for Mobile Communication (GSM) in Nigeria (2012)

Unexpectedly, the level of patronage being experienced in Global System for Mobile Communication (GSM) in Nigeria is overwhelming. This is as a result of freedom of calling from anywhere at anytime and clarity of the voice enjoyed in GSM since it is on a digital technology platform. This has brought a lot of congestion in the network resulting in poor services by the operators. This research has developed a management algorithm for the management of the congestion experienced in the GSM network in Nigeria. It explores the use of Erlang-B in determining the appropriate probability level for some range of subscribers. Thereafter, when there is congestion, block time sharing, dynamic allocation without time slicing, dynamic allocation time slicing with signal sensing, frequently recent call allocation, and priority allocation algorithms were developed to manage the congestion. Furthermore, a hybrid algorithm was developed that integrates all the algorithms together in other to manage the congestion considering all the strengths and constraints of each algorithm. If the recommended congestion management algorithm is followed comprehensibly, the congestion problem on the GSM network will be reduced drastically.

Ionization Characteristics of Atmospheric Pressure Ionization by Corona Discharge (1976)

Ionization characteristics of Atmospheric Pressure Ionization(API)by corona discharge are investigated in relation to total discharge current and needle electrode position. Cluster ions produced in the ionization region are dissociated into molecular ions by a collision induced dissociation method. Calibration curves relating nitrobenzene molecular ion intensity and injected sample size are obtained for wet nitrogen carrier. Ion intensity is found to increase linearly for sample sizes up to 2ng/sec., however, saturation occurs in a large sample size region. Ionization efficiency is found to increase as the needle electrode approaches the aperture electrode. It is close to 100% when the needle position is 3mm from the aperture electrode.
Polarization entanglement visibility of photon pairs emitted by a quantum dot embedded in a microcavity (2005)

We study the photon emission from a quantum dot embedded in a microcavity. Incoherent pumping of its excitons and biexciton provokes the emission of leaky and cavity modes. By solving a master equation we obtain the correlation functions required to compute the spectrum and the relative efficiency among the emission of pairs and single photons. A quantum regime appears for low pumping and large rate of emission. By means of a post-selection process, a two beams experiment with different linear polarizations could be performed producing a large polarization entanglement visibility precisely in the quantum regime.
The Pharmacokinetics of Bumetanide in the Newborn Infant (1997)

This study characterizes the pharmacokinetics of bumetanide after an intravenous dose of 0.05 or 0.10 mg/kg to 14 neonates (weight range 820-4,000 g; gestational age 26-40 weeks) during the first week of life. Blood samples and urine were collected for up to 12 h after dosing. Estimated serum clearance was 0.2-1.0 ml/min.kg (range), volume of distribution was 0.22 l/kg (range 0.11-0.32 l/kg), and the harmonic mean half-life was 6-7 h (range of 4-19 h). Nonrenal clearance accounted for 58-97% of the serum clearance with the presence of certain oxidative metabolites of bumetanide in the urine. These findings suggest higher dosing requirements and prolonged intervals as compared to adults. Utilizing these pharmacokinetic data, pharmacodynamic and ototoxicity studies should be conducted to establish a safe and effective neonatal dose.
Efficacy and tolerability of vildagliptin vs. pioglitazone when added to metformin: a 24‐week, randomized, double‐blind study* (2007)

When added to metformin, the efficacy of vildagliptin is non-inferior to that of pioglitazone. The treatments were similarly well tolerated, but only pioglitazone increased body weight.
The thickness of the intestinal mucous layer in the colon of rats fed various sources of non-digestible carbohydrates is positively correlated with the pool of SCFA but negatively correlated with the proportion of butyric acid in digesta (2009)

The present experiment aimed to study the influence of six sources of non-digestible carbohydrates (NDC) on the mucous layer in the colon of rats. The NDC sources used were as follows: cellulose (C); pectin (P); inulin; resistant starch (RS); barley hulls. The diets contained 108-140 g NDC/kg DM. A fibre-free (FF) diet served as a control. The diets were fed to forty-eight rats for 34-41 d. The thickness of the total mucous layer in the colon was increased (P < 0.05) in rats fed C, P and RS when compared with rats fed a FF diet. In the colon, positive correlations were observed between the total thickness of the mucous layer and the area of neutral mucins, the pool of SCFA and the pool of acetic acid, while it was negatively correlated with the proportion of butyrate. The total thickness of the mucous layer was not correlated with the MUC gene transcription. The transcription of the gene MUC2 was negatively correlated (P = 0.04), whereas the transcription of MUC3 was positively correlated (P = 0.05) with the butyrate pool in the caecum. No correlations between the MUC2 or MUC3 transcription and SCFA were found in the colon. Hence, the regulation of the MUC genes differs between the compartments of the hindgut and, within compartments, the MUC genes may be regulated differently. In conclusion, a diet providing a large pool of SCFA with a low proportion of butyrate in the colon stimulates the formation of a thick mucous layer, which probably benefits intestinal health.
