Line-drawing algorithms for parallel machines (1990)

The fact that conventional line-drawing algorithms, when applied directly on parallel machines, can lead to very inefficient codes is addressed. It is suggested that instead of modifying an existing algorithm for a parallel machine, a more efficient implementation can be produced by going back to the invariants in the definition. Popular line-drawing algorithms are compared with two alternatives; distance to a line (a point is on the line if sufficiently close to it) and intersection with a line (a point on the line if an intersection point). For massively parallel single-instruction-multiple-data (SIMD) machines (with thousands of processors and up), the alternatives provide viable line-drawing algorithms. Because of the pixel-per-processor mapping, their performance is independent of the line length orientation.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Continuous culture studies on the synthesis of capsular polysaccharide by <i>Klebsiella pneumoniae</i> K1 (1994)

The synthesis of capsular polysaccharide by Klebsiella pneumoniae K1 was investigated in a minimal salts medium by continuous culture. The organism produced larger amounts of polysaccharide under nitrogen-limited conditions than under carbon-limited conditions. The synthesis of polysaccharide was dependent not only on the availability of excess carbon, but also on growth rate. The rate of polysaccharide synthesis was greatest at low dilutions, low temperature (30 degrees C) and at neutral pH. Prolonged growth in nitrogen-limited culture resulted in the development of non-mucoid variants, possibly due to a selective growth advantage over mucoid cells. The non-mucoid isolate was more susceptible to some bacteriophages, possibly due to the reduction nor absence of capsular polysaccharide.

Callus formation and organogenesis by explants of six <i>Lycopersicon</i> species (1983)

Stem and hypocotyl explants of six Lycopersicon species, L. esculentum var. cerasiformae, L. cheesmanii, L. hirsutum, L. pimpinellifolium, L. peruvianum, and L. glandulosum, were examined for ability to form callus, adventitious shoots, and adventitious roots on media containing varying levels of indole acetic acid (IAA) and kinetin. Callus growth of L. peruvianum and L. glandulosum explants was better than that of the other species tested. Stem explants tended to form more callus than hypocotyl explants. Shoot formation by hypocotyl explants was superior to stem explants for all species and at nearly all hormone levels. Hypocotyl explants of L. peruvianum and L. glandulosum showed the highest levels of shoot formation, and L. cheesmanii and L. esculentum var. cerasiformae hypocotyl explants showed good shoot formation on media containing 3 mg/L kinetin and 0.3 or 1 mg/L indole acetic acid. No shoot formation was observed by L. hirsutum explants, and L. pimpinellifolium explants gave only a poor response. Shoot formation by stem explants was obtained only with L.. esculentum var. cerasiformae and L. glandulosum. When callus of the six species, subcultured for 63 days on a medium optimal for callus growth, was subcultured on shoot-forming media, only callus of L. peruvianum and L. glandulosum subsequently formed shoots. Callus of L. glandulosum has retained its morphogenic potential for 1 year in culture and can be used to initiate liquid suspension cultures.
Imaging of the aging brain. Part I. Normal findings. (1988)

A thorough knowledge of the normal changes that occur in the brain with age is critical before abnormal findings are analyzed. Magnetic resonance (MR) imaging improves the ability to distinguish normal and abnormal findings in the brain. The major changes that may occur in elderly individuals without neurologic deficits include enlargement of the ventricles, cortical sulci, and vermian subarachnoid spaces; multifocal areas of hyperintensity in the white matter and basal ganglia; a progressive prominence of hypointensity on T2-weighted images of the putamen, almost equal to that of the globus pallidus; an increase in the oxygen extraction ratio with normal or mildly decreased neuron metabolism; arteriosclerosis in large and small arteries and amyloid angiopathy in leptomeningeal cortical vessels; and decreased dopamine receptor binding in the corpus striatum. Since approximately half of the elderly population exhibits only negligible brain alterations, MR imaging may facilitate the distinction between usual (no neurologic dysfunction) and successful (no brain or vascular changes) aging.

Improving 16 kb/s G.728 LD-CELP speech coder for frame erasure channels (2002)

We have improved G.728 output speech quality for frame erasure channels. Three cases are considered: (1) no change to G.728, (2) change only the G.728 decoder, and (3) change both the encoder and decoder. In case 1, we synthesize a bit-stream during erased frames so that the decoder decodes an excitation with low energy or with characteristics similar to the excitation of previous good frames. In case 2, the gain-scaled excitation and LPC coefficients are extrapolated, and vital operations of backward LPC and gain adaptations are continued. Case 3 adds spectral smoothing and increases bandwidth expansion for the LPC and gain predictors. These techniques are quite effective, as the speech quality degradation due to 1% frame erasures ranges from just slightly noticeable in case 1 to almost unnoticeable in case 3. For case 3, the output speech is still intelligible for frame erasure rates up to 10% or even 20%.
Spatially resolved thermoreflectance study of facet temperature in quantum cascade lasers (2005)

Abstract In the present work, we use spatially resolved thermoreflectance (SR TR) to measure temperature distribution over the facet of pulsed operated quantum cascade lasers. The laser beam probes the change in the refractive index caused by current‐induced heating of working device. The technique has a spatial resolution of about ∼1 μm and temperature resolution better than 1 K. It gives an insight into distribution and relative importance of heat sources within the laser.

The 10 KM/S, 10 KG railgun (1991)

The system design for a railgun powered by capacitor-based energy stores distributed along its length is presented. It is assumed that it is required to accelerate a mass of 10 kg to a velocity of 10 km/s. Parameters for the railgun and its energy stores are derived, and the performance of the system is computed with particular attention being paid to the efficiency with which store energy is converted to launch-package kinetic energy. It is shown that efficiencies of 90% can be expected from a properly designed system.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Immigrants, unions, and the new US labor market (2006)

In recent years, New Yorkers have been surprised to see workers they had taken for granted-Mexicans in greengroceries, West African supermarket deliverymen and South Asian limousine drivers-striking, picketing, and seeking support for better working conditions. Suddenly, businesses in New York and the nation had changed and were now dependent upon low-paid immigrants to fill the entry-level jobs that few native-born Americans would take. Immigrants, Unions, and the New U.S. Labor Market tells the story of these workers' struggle for living wages, humane working conditions, and the respect due to all people. It describes how they found the courage to organize labor actions at a time when most laborers have become quiescent and while most labor unions were ignoring them. Showing how unions can learn from the example of these laborers, and demonstrating the importance of solidarity beyond the workplace, Immanuel Ness offers a telling look into the lives of some of America's newest immigrants.

Oncometabolites: tailoring our genes (2015)

Increased glucose metabolism in cancer cells is a phenomenon that has been known for over 90 years, allowing maximal cell growth through faster ATP production and redistribution of carbons towards nucleotide, protein and fatty acid synthesis. Recently, metabolites that can promote tumorigeneis by altering the epigenome have been identified. These 'oncometabolites' include the tricarboxylic acid cycle metabolites succinate and fumarate, whose levels are elevated in rare tumours with succinate dehydrogenase and fumarate hydratase mutations, respectively. 2-Hydroxyglutarate is another oncometabolite; it is produced de novo as a result of the mutation of isocitrate dehydrogenase, and is commonly found in gliomas and acute myeloid leukaemia. Interestingly, the structural similarity of these oncometabolites to their precursor metabolite, α-ketoglutarate, explains the tumorigenic potential of these metabolites, by competitive inhibition of a superfamily of enzymes called the α-ketoglutarate-dependent dioxygenases. These enzymes utilize α-ketoglutarate as a cosubstrate, and are involved in fatty acid metabolism, oxygen sensing, collagen biosynthesis, and modulation of the epigenome. They include enzymes that are involved in regulating gene expression via DNA and histone tail demethylation. In this review, we will focus on the link between metabolism and epigenetics, and how we may target oncometabolite-induced tumorigenesis in the future.
Ring Opening of 3‐Bromo‐2‐Isoxazolines to β‐Hydroxy Nitriles (2004)

Abstract 3‐Bromo‐2‐isoxazolines were converted to the corresponding β‐hydroxy nitriles by treatment with sodium iodide in the presence of either chlorotrimethylsilane or para‐toluenesulfonic acid. Both methods gave β‐hydroxy nitriles under relatively mild conditions in good to moderate yields for a variety of substituted 3‐bromo‐2‐isoxazolines.

Extremum control of continuous systems (1966)

An extremum control system is considered which consists of the following in cascade: an integrator, a function of the parabolic type and a first-order system. A method is presented for determining and maintaining the extremum in the presence of disturbances. The method suggested consists of perturbing the system input, then using the discontinuities in an appropriate derivative of the system output to determine the extremum. The advantage gained is speed in identifying the extremum independent of the initial conditions. Analog and digital computer results are given.
1-Gword/s pseudorandom word generator (1989)

An integrated circuit that generates 16-bit pseudorandom words at up to 1 Gword/s is presented. The concept of a pseudorandom word sequence is introduced. The pseudorandom words shown have excellent properties for testing serial or parallel components and data links. If serialized, the words would form a pseudorandom bit sequence with a potential maximum serial bit rate of 16 Gb/s. The circuit was implemented in an advanced silicon bipolar process with an f/sub T/ of 10 GHz. The chip includes 16 output drivers, with adjustable amplitude and offset, capable of driving 25- Omega loads with 0.8-V swings and 400-ps rise times. Total chip dissipation is under 4 W on a 2-mm*2-mm die.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Evaluation of the size of time windows for the travelling salesman problem in delivery operations (2020)

Abstract A great challenge in operational research is to apply time-efficient algorithms to find the optimal solutions to the travelling salesman problem (TSP) and its many variations. The TSP with time windows (TSPTW) arises due to intense pressure for business to improve customer service. As online shopping becomes more popular, customer satisfaction increases if customers can decide when their orders are delivered to them. Customers may choose a time window, which is defined by an earliest delivery time and a latest delivery time, during which the package is delivered. Delivering packages to multiple customers is a typical TSPTW. One main challenge for a delivery business is to determine the size of the time window (i.e., the difference between the latest and earliest delivery times), which affects delivery cost and customer satisfaction. Although many previous studies investigated the TSPTW, none of those focused on the size of time windows. This study is the first that experiments with different time window sizes and determines their impact on tour duration, customer satisfaction, and solution time of the optimal delivery routes. The experiment results show that increasing the size of the time window decreases tour duration and customer satisfaction and increases solution time. Decreasing the size of the time window increases tour duration and customer satisfaction and decreases solution time. A small solution time is necessary for the scheduling of deliveries to many customers. A large solution time prevents a delivery business from delivering packages using optimal routes, which increases delivery cost and decreases customer satisfaction. The results of this study indicate that a general guideline for business is to allow customers to choose a time window size that is within the cost limit but is sufficiently small to maximize customer satisfaction and optimize delivery routes.
The effect of non-woven PP fabric covers on the yielding and the fruit quality of field-grown sweet peppers (2010)

In recent years in Poland there has been an increasing interest in the field growing of sweet peepers, both among producers and consumers. Therefore, research should be conducted to select cultivars well adapted to less favorable temperature conditions and suitable for cultivation in the field, and to increase their yield. A field experiment was carried out in the years 2006–2008 in the Garden of the Research and Experimental Station of the University of Warmia and Mazury in Olsztyn to determine the effect on plant cover on the yield and the content of dry matter and organic compounds in sweet pepper fruit. In comparison with the control treatment (without protective cover), the use of non-woven PP covers increased the marketable yield of sweet pepper cv. Iga, Lena and Mira, and it decreased the marketable yield of cv. Zorza. Sweet pepper fruit in the control treatment had the highest average dry matter content. The use of non-woven PP covers contributed to dry matter accumulation only in the fruit of cv. Zorza. The fruit of sweet pepper plants grown without protective cover contained greater amounts of L-ascorbic acid. Non-woven PP covers had no effect on the concentrations of total and reducing sugars, which were highest (subject to cultivar and cultivation method) in 2007.
El eros periodístico de Alfonso Reyes (2013)

Periodismo es informacion de actualidad y periodista es aquella persona que investiga la realidad para dar a conocer noticias o interpretarlas y comentarlas en un medio masivo a fin de sobrevivir decorosamente mediante una paga. Siendo asi, Alfonso Reyes fue un hombre de la prensa, en su tiempo de apuros economicos, y debido a sus colaboraciones en algunas publicaciones periodicas logro salvar su situacion precaria en Madrid. Ergo, Alfonso Reyes es un periodista en sus primeros textos en Espana, que tienen el sello del oficio con proyeccion hacia la literatura, ya que esta fue su vida y su vida fue la literatura, segun expresion del critico Emmanuel Carballo.
