<scp>l</scp>-Citrulline ameliorates chronic hypoxia-induced pulmonary hypertension in newborn piglets (2009)

Newborn piglets develop pulmonary hypertension and have diminished pulmonary vascular nitric oxide (NO) production when exposed to chronic hypoxia. NO is produced by endothelial NO synthase (eNOS) in the pulmonary vascular endothelium using l-arginine as a substrate and producing l-citrulline as a byproduct. l-Citrulline is metabolized to l-arginine by two enzymes that are colocated with eNOS in pulmonary vascular endothelial cells. The purpose of this study was to determine whether oral supplementation with l-citrulline during exposure of newborn piglets to 10 days of chronic hypoxia would prevent the development of pulmonary hypertension and increase pulmonary NO production. A total of 17 hypoxic and 17 normoxic control piglets were studied. Six of the 17 hypoxic piglets were supplemented with oral l-citrulline starting on the first day of hypoxia. l-Citrulline supplementation was provided orally twice a day. After 10 days of hypoxia or normoxia, the animals were anesthetized, hemodynamic measurements were performed, and the lungs were perfused in situ. Pulmonary arterial pressure and pulmonary vascular resistance were significantly lower in hypoxic animals treated with l-citrulline compared with untreated hypoxic animals (P < 0.001). In vivo exhaled NO production (P = 0.03) and nitrite/nitrate accumulation in the perfusate of isolated lungs (P = 0.04) were significantly higher in l-citrulline-treated hypoxic animals compared with untreated hypoxic animals. l-Citrulline supplementation ameliorated the development of pulmonary hypertension and increased NO production in piglets exposed to chronic hypoxia. We speculate that l-citrulline may benefit neonates exposed to prolonged periods of hypoxia from cardiac or pulmonary causes.
Residential Demand Response: Dynamic Energy Management and Time-Varying Electricity Pricing (2015)

Demand response programs are currently being proposed as a solution to deal with issues related to peak demand and to improve the operation of the electric power system. In the demand response paradigm, electric utilities provide incentives and benefits to private consumers as a compensation for their flexibility in the timing of their electricity consumption. In this paper, a dynamic energy management framework, based on highly resolved energy consumption models, is used to simulate automated residential demand response. The models estimate the residential demand using a novel bottom-up approach that quantifies consumer energy use behavior, thus providing an accurate estimation of the actual amount of controllable resources. The optimal schedule of all of the controllable appliances, including plug-in electric vehicles, is found by minimizing consumer electricity-related expenditures. Recently, time-varying electricity rate plans have been proposed by electric utilities as an incentive to their customers with the objective of re-shaping the aggregate demand. Large-scale simulations are performed to analyze and quantitatively assess the impact of demand response programs using different electricity price structures. Results show that simple time-varying electricity price structures, coupled with large-scale adoption of automated energy management systems, might create pronounced rebound peaks in the aggregate residential demand. To cope with the rebound peaks created by the synchronization of the individual residential demands, innovative electricity price structures-called Multi-TOU and Multi-CPP-are proposed.
High efficiency and power density GaN-based LED driver (2016)

LED lighting is becoming more attractive and popular due to its high efficiency, long lifetime, instant brightness and ability to dim. But LEDs are powered by DC, which requires a rectifier to allow it to run off the AC utility grid. These converters must have small form factors and operate in high ambient temperatures due to the close proximity of the LED light. Gallium Nitride (GaN) based switched mode power supplies have the ability to increase switching frequencies to allow for form factors small enough to enable new applications with stricter space requirements. But to achieve this size reduction, the switching frequency must operate in the megahertz range, which requires soft switching techniques to achieve acceptable performance. A small and simple analog hysteresis-controlled valley-switched floating buck converter is proposed to solve these problems. This solution has a minimal component count while maintaining similar performance to existing solutions. A 20W prototype is built to verify the performance of the converter, which is measured to have a size reduction of 1.87× of the power stage when compared to an existing commercial product while achieving an efficiency of 91.2%, an input current THD of 15.9% and PF of 0.976.
Fluoreszierende Stoffe aus <i>Drosophila melanogaster</i>. 14. Mitteilung [1]. Eine Synthese des Biopterins (1969)

Abstract 2,4,5‐Triamino‐6‐oxo‐1, 6‐dihydropyrimidin wird mit 1‐(Benzylphenylhydrazino)‐5‐desoxy‐ L ‐ribulose in wässrigem Methanol unter N 2 kondensiert. Die Mischung der gebildeten Tetrahydropterine wird zu den entsprechenden Pterinen oxydiert, wobei die polyhydroxyalkylierte Kette teilweise abgespalten wird. Diese Pterine stellen eine Mischung von Biopterin, wenig seines 7‐Isomeren und viel Pterin sensu stricto dar. Aus dieser Mischung lässt sich reines Biopterin durch Chromatographie an Dowex 1 × 8 gewinnen. Das synthetische und das aus Drosophila melanogaster isolierte Biopterin sind völlig identisch.
New method of carbon nanotube growth by ion beam irradiation (1996)

We report a new method of carbon nanotube growth by the argon ion beam irradiation of amorphous carbon under high vacuum conditions of 4×10−5 Torr. Earlier, carbon nanotubes have been produced at gas pressures above 100 Torr. The incident angle of the ion beam was normal to the target surface, and the acceleration ion energy was 3 keV. Nanotubes are produced outside the sputtering region on the target surface after ion irradiation. The tubes have multilayered walls, the distance between carbon layers is 0.34 nm, and wall thickness of tubes ranges from 10 to 15 sheets.
Percolation model for electron conduction in films of metal nanoparticles linked by organic molecules (2002)

We have investigated theoretically and experimentally the temperature dependence of the conductance of films of Au nanoparticles linked by alkane dithiol molecules in the temperature range between 5 and 300 K. Conduction in these films is due to tunneling of single electrons between neighboring metal nanoparticles via the linker molecules. During tunneling an electron has to overcome the Coulomb charging energy. We find that the observed temperature dependence of the conductance is non-Arrhenius-like and can be described in terms of a percolation theory which takes account of disorder in the system. Disorder in our nanoparticle films is caused by variations in the nanoparticle size, fluctuations in the separation gaps between adjacent nanoparticles and by offset charges. To explain in detail our experimental data, a wide distribution of separation gaps and charging energies has to be assumed. We find that a wide Coulomb charging energy distribution can arise from random offset charges even if the nanoparticle size distribution is narrow.
Evaluation of Intensity-Modulated Recording for Ultrasonic Diagnosis (1968)

An evaluation of available intensity-modulated recording systems has shown that they do not produce identical records from the same echo pattern. Differences in the records are due to two factors: the video time constants used and whether or not the zero-signal level or “base line” is stabilized. Several tests are described by which the processing inherent in a particular type of equipment can be assessed and by means of which these changes can be demonstrated. Because of these differences in apparatus, it appears that conclusions about the usefulness of ultrasonic diagnosis depend on the particular equipment.
Simplification of adult mosquito bioassays through use of time-mortality determinations in glass bottles. (1998)

A simple method is described for treating 250-ml glass Wheaton bottles with insecticide, and using them as test chambers for detecting insecticide resistance in mosquito and sandfly populations. The methods for treating bottles, obtaining baseline data, and applying this technique to insects from the field are described. Sample data are presented from tests run on different vector species using a variety of insecticides. Time-mortality data from the bottle bioassay are presented alongside results from biochemical detection methods applied to the same mosquito population. The potential role, advantages, and limitations of the time-mortality bottle method are discussed.
WAVE: Popularity-based and collaborative in-network caching for content-oriented networks (2012)

In content-oriented networking, content files are typically cached in network nodes, and hence how to cache content files is crucial for the efficient content delivery and cache storage utilization. In this paper, we propose a content caching scheme, WAVE, in which the number of chunks to be cached is adjusted based on the popularity of the content. In WAVE, an upstream node recommends the number of chunks to be cached at its downstream node, which is exponentially increased as the request count increases. Simulation results reveal that the average hop count of content delivery of WAVE is lower than other schemes, and the inter-ISP traffic volume of WAVE is the second lowest (CDN is the lowest). Also, WAVE achieves higher cache hit ratio and fewer frequent cache replacements than other on-demand caching strategies.

Incomplete hypercubes (1988)

Since a k-dimensional hypercube has 2/sup k/ vertices, these systems are restricted to having exactly 2/sup k/ computing nodes. Because system sizes must be a power of two, there are large gaps in the sizes of systems that can be built with hypercubes. Routing and broadcast algorithms are presented for hypercubes that are missing certain of their nodes, called incomplete hypercubes. Unlike hypercubes, incomplete hypercubes can be used to interconnect systems with any number of processors. The routing and broadcast algorithms for incomplete hypercubes are shown also to be simple and deadlock-free.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Effect of thiocyanate ingestion through milk on thyroid hormone homeostasis in women (1997)

A thyroid-hormonal evaluation of thirty-five women consuming commercially packed milk containing thiocyanate was carried out. The mean serum thiocyanate concentration, which was measured by the FeCl3 colour test, was significantly higher (P < 0.01) than that of control subjects. Serum thyroxine (T4), triiodothyronine (T3) and thyroid-stimulating hormone (TSH) concentrations of exposed women were compared with those of thirty-five control subjects. Thiocyanate ingestion was associated with lower levels of T4 (P < 0.01) and higher levels of TSH (P < 0.01) compared with the control subjects. T3 was found to be higher in the women consuming thiocyanate-containing milk but the difference was not significant. The serum T4 level was found to be negatively correlated (r -0.359, P < 0.05) while the TSH level was positively correlated (r 0.354, P < 0.05) with thiocyanate concentration in the exposed group. From this study, it appears that ingestion of milk with added thiocyanate impairs thyroid function.
[The design and application of domestic mid-IR fiber optics]. (2004)

The combination of mid-IR fiber optics and FTIR has made the non-invasive determination of samples in situ, with long distances, and in vivo possible. In this paper domestic mid-IR fiber optics was improved to investigate the transmission ability of fiber optics and its application to the sample determination. New design was applied to obtaining one bare fiber optics, which has a minor energy loss and higher signal-to-noise ratio. The spectra of H2O/EtOH and tissue samples were measured using the new designed fiber optics and the results show that home-made mid-IR fiber optics can be applied to the field of determination of general and biological samples.
Dependence of the microstructure, residual stresses and texture of AA 6013 friction stir welds on the welding proces (2003)

Abstract The microstructure, the residual stresses and the texture of friction stir welds of 4 mm thick samples made of a 6013 Al–Mg–Si–Cu alloy in T4 state were investigated in order to study the influence of the friction stir welding process on the material and in order to determine the influence of different welding parameters. The results of the investigations reveal the influence of the process parameters (welding speed, tool diameter and rotational speed) on the weld properties such as the microstructure, the precipitation state, the hardness, the texture and the residual stresses. The formation of the residual stresses and their distribution is explained based on an existing, simple thermal model for the friction stir welding and on a classical model for the formation of the residual stresses in conventional fusion welding.
On finding minimum routes in a network with turn penalties (1961)

In some highway engineering work it is necessary to find a route between two points in a city's street and freeway network such that a function of time and distance is minimized. Such a route is called a “best” route, and finding such a route is not a difficult task. The Moore Algorithm 1 accomplishes this quite nicely, and using that algorithm and a procedure developed by Hoffman and Pavley 2 (programmed by them for the IBM 650) it is even possible to find the “ N th best path.”

Cold-restraint stress increases rat fecal pellet output and colonic transit (1990)

Increased fecal pellet output that occurs during cold-restraint stress (CRS) was evaluated systematically. Free-feeding rats, which exhibit a reduced occurrence of gastric ulcers under these conditions, were studied. CRS significantly increased fecal pellet production and fluid content. However, the fecal output produced during CRS was not associated with increased gut secretory activity or somatic motor activity associated with cold restraint and did not occur in anesthetized animals. Cold and restraint stress were additive in producing increased fecal output. Significant dose-related decreases in fecal output were produced by drugs that decrease gut transit (i.e., B-HT 920, clonidine, Lomotil, loperamide, and lidamidine). Anticholinergic-antisecretory drugs, antidepressants, and tranquilizers had little effect on fecal output or fluid content. Changes in gastrointestinal transit did not contribute to the increased fecal output during CRS. Transit in the lower small intestine was not altered, but the cecum tended to empty more contents into the large intestine during CRS. Colonic transit was dramatically affected by CRS, which eliminated retrograde transit and produced the evacuation of the majority of colonic contents. The increased colonic transit produced by CRS was decreased in a dose-related fashion by hexamethonium, nifedipine, loperamide, and B-HT 920. In several time-response and drug-inhibition studies during CRS, both fecal pellet output and colonic transit were affected similarly. These data indicate that CRS appears to change central nervous system output to the colon and that it alters colonic smooth muscle motility in a manner that facilitates colonic transit and evacuation. Small intestinal transit is not involved in this phenomenon and is regulated differently during CRS.
Effects of Verapamil SR and Atenolol on 24-Hour Blood Pressure and Heart Rate in Hypertension Patients with Coronary Artery Disease... (2015)

Elevated night-time blood pressure (BP) and heart rate (HR), increased BP and HR variability, and altered diurnal variations of BP and HR (nighttime dipping and morning surge) in patients with systemic hypertension are each associated with increased adverse cardiovascular events. However, there are no reports on the effect of hypertension treatment on these important hemodynamic parameters in the growing population of hypertensive patients with atherosclerotic coronary artery disease (CAD). This was a pre-specified subgroup analysis of the INternational VErapamil SR-Trandolapril STudy (INVEST), which involved 22,576 clinically stable patients aged ≥50 years with hypertension and CAD randomized to either verapamil SR- or atenolol-based hypertension treatment strategies. The subgroup consisted of 117 patients undergoing 24-hour ambulatory monitoring at baseline and after 1 year of treatment. Hourly systolic and diastolic BP (SBP and DBP) decreased after 1 year for both verapamil SR- and atenolol-based treatment strategies compared with baseline (P<0.0001). Atenolol also decreased hourly HR (P<0.0001). Both treatment strategies decreased SBP variability (weighted standard deviation: P = 0.012 and 0.021, respectively). Compared with verapamil SR, atenolol also increased the prevalence of BP and HR night-time dipping among prior non-dippers (BP: OR = 3.37; 95% CI: 1.26 – 8.97; P = 0.015; HR: OR = 4.06; 95% CI: 1.35-12.17;P = 0.012) and blunted HR morning surge (+2.8 vs. +4.5 beats/min/hr; P = 0.019). Both verapamil SR- and especially atenolol-based strategies resulted in favorable changes in ambulatory monitoring parameters that have been previously associated with increased adverse cardiovascular events.

Revisiting Dilated Convolution: A Simple Approach for Weakly- and Semi-Supervised Semantic Segmentation (2018)

Despite the remarkable progress, weakly supervised segmentation approaches are still inferior to their fully supervised counterparts. We obverse the performance gap mainly comes from their limitation on learning to produce high-quality dense object localization maps from image-level supervision. To mitigate such a gap, we revisit the dilated convolution [1] and reveal how it can be utilized in a novel way to effectively overcome this critical limitation of weakly supervised segmentation approaches. Specifically, we find that varying dilation rates can effectively enlarge the receptive fields of convolutional kernels and more importantly transfer the surrounding discriminative information to non-discriminative object regions, promoting the emergence of these regions in the object localization maps. Then, we design a generic classification network equipped with convolutional blocks of different dilated rates. It can produce dense and reliable object localization maps and effectively benefit both weakly- and semi- supervised semantic segmentation. Despite the apparent simplicity, our proposed approach obtains superior performance over state-of-the-arts. In particular, it achieves 60.8% and 67.6% mIoU scores on Pascal VOC 2012 test set in weakly- (only image-level labels are available) and semi- (1,464 segmentation masks are available) supervised settings, which are the new state-of-the-arts.
