Design and implementation of a high performance induction motor servo drive (1993)

In the paper, the design and implementation of a high performance induction motor servo drive system is presented. An experimental indirect field-orientated induction motor drive system is implemented, and its dynamic model is built up using stochastic techniques. To obtain good dynamic responses both in the position command tracking and load regulation characteristics, a position servo controller with two degrees of freedom is proposed. The parameters of the controller are found using a systematic design procedure according to the given drive specifications. The theoretic basis of the design procedure is developed in some detail. Having tested the performance of the controller by simulation, the microcomputer-based realisation of the designed controller has been successfully implemented. Some experimental results are given to demonstrate the effectiveness of the proposed position servo controller.
Optimization of the travel time of an electric vehicle with consideration of the recharging terminals (2021)

This paper deals with the computation of the energy profile of a battery electric vehicle in order to find the optimal path in terms of travel time on a defined route in the presence of recharging terminals. The model used in this study to calculate the energy profile must respect constraints such as speed limits, desired initial and final battery energy states, and maximum terminal power. This problem can be written as an Optimal Control Problem and will be solved using the dynamic programming method in order to find the optimal speed and charging quantity at the terminal to save time. The results from a defined scenario show that recharging is done in favour of terminals with a higher maximum power and that our vehicle is constantly driving at the maximum speed allowed. The vehicle can also adapt its speed to reach the next charging station with the consideration of a waiting time at a station. The Dynamic Programming method allows us to respect the final energy constraints and shows that charging at high-powered terminals saves time.
Engineering of Ru(<scp>ii</scp>) dyes for interfacial and light-harvesting optimization (2013)

A new Ru(II) dye, Ru(L1)(L2) (NCS)2, L1 = (4-(5-hexylthiophen-2-yl)-4'(4-carboxyl-phenyl 2,2'-bipyridine) and L2 = (4-4'-dicarboxy-2,2'-bipyridine), labelled MC112, based on a dissymmetric bipyridine ligand for improved interfacial and optical properties, was synthesized and used in DSCs, yielding photovoltaic efficiencies of 7.6% under standard AM 1.5 sunlight and an excellent device stability. Increased light harvesting and IPCE maximum were observed with MC112 compared to the prototypical homoleptic N719 dye, due to the functionalized bipyridyne ligand acting as an antenna. In addition, the mixed bipyridyne ligand allowed MC112 binding to TiO2 to occur via three anchoring carboxylic groups, thus exhibiting similar interfacial properties to those of the N719 dye. DFT/TDDFT calculations were performed on the new dye, both in solution and adsorbed on a TiO2 surface model, revealing that the peculiar photovoltaic properties of the MC112 dye are related to its anchoring mode. The new design rule thus allows us to engineer both light-harvesting and interfacial properties in the same dye.

Time-lapsed integrated Raman and angular scattering microscopy of single cells (2011)

Integrated Raman- and Angular-scatteringMicroscopy (IRAM) combines two light scattering techniques to make chemical and morphological measurements of intact, single cells without the use of external labeling. IRAM has previously demonstrated its ability to differentiate between activated and non-activated CD8+ T cells based on both chemical and morphological differences. Activated cells showed an increase in protein and lipid content as well as an increase in the size and number of 0.5-1.0 &mu;m diameter scatterers (likely lysosomes). Recent improvements to the IRAM system enable studies over an extended period of time. The applications of IRAM to chemical and structural changes of single cells during biological processes and treatments will be discussed.

Мотивация студентов вузов в сфере физической культуры и спорта (2014)

In Russia the year 2013 was declared crucial in respect to university sport. At the same time the scientific and technical progress, being one of the reasons for hypodynamia, requires from future specialists high qualification and high working capacity. Students, especially at the initial training phase, are the most vulnerable among young people, because they face many difficulties associated with the increase in the learning load, hypodynamia, relative freedom of college life, problems in social and interpersonal communication. Numerous studies show that sports activity among young people is clearly insufficient at present. In this context studies of interests and needs of modern young people in the sphere of physical culture and sport, development of methods of motivational stimulation of their motor activity acquire great importance and relevance. The purpose of the present study was to examine the ways of stimulation of motivation to classes of physical education and sport. The value system of values influences directly formation of the motivational structure of the personality of a student as a subject implementation of his inner choice and therefore on the basis it is being formed on: fashion, social environment, education, etc., i.e., the values the community is offering to a person. The process of formation of the interest in classes of physical education and sport is not a multi-stage process. Motivation is defined as a set of determining behavior factors, a combination of psychological reasons of human behavior, its beginning, direction and activity, motives. Based on the studies, changes and improvements are to be introduced to the organization of physical education classes to in order to enhance students' motivation to them. Classes organized this way have a complex effect on the body, promote the development of physical, mental, moral and volitional qualities, endurance, mutual assistance, are a great alternative to conventional physical education classes and stimulate the interest in physical culture and active way of life.

Syntheses, structures and redox properties of some complexes containing the Os(dppe)Cp* fragment, including [{Os(dppe)Cp*}2(µ-CCCC)] (2007)

The sequential conversion of [OsBr(cod)Cp*] (9) to [OsBr(dppe)Cp*] (10), [Os([=C=CH2)(dppe)Cp*]PF6 ([11]PF6), [Os(C triple bond CH)(dppe)Cp*] (12), [{Os(dppe)Cp*}2{mu-(=C=CH-CH=C=)}][PF6]2 ([13](PF6)2) and finally [{Os(dppe)Cp*}(2)(mu-C triple bond CC triple bond C)] (14) has been used to make the third member of the triad [{M(dppe)Cp*}2(mu-C triple bond CC triple bond C)] (M = Fe, Ru, Os). The molecular structures of []PF6, 12 and 14, together with those of the related osmium complexes [Os(NCMe)(dppe)Cp*]PF6 ([15]PF6) and [Os(C triple bond CPh)(dppe)Cp*] (16), have been determined by single-crystal X-ray diffraction studies. Comparison of the redox properties of 14 with those of its iron and ruthenium congeners shows that the first oxidation potential E1 varies as: Fe approximately Os < Ru. Whereas the Fe complex has been shown to undergo three sequential 1-electron oxidation processes within conventional electrochemical solvent windows, the Ru and Os compounds undergo no fewer than four sequential oxidation events giving rise to a five-membered series of redox related complexes [{M(dppe)Cp*}2(mu-C4)]n+ (n = 0, 1, 2, 3 and 4), the osmium derivatives being obtained at considerably lower potentials than the ruthenium analogues. These results are complimented by DFT and DT DFT calculations.
Comparison of carcass and lingual examination for the diagnosis of porcine cysticercosis in Nepal (2008)

Abstract: With the increase in pig production and consumption by smallholder, there have been problems with zoonotic parasitic diseases especially porcine cysticercosis in Nepal. Materials and Methods: This study was conducted among 320 pigs from four different slaughter slabs of Chitwan and Kathmandu valley during June to November 2006. The objectives of this study were to determine prevalence by lingual examination, carcass examination and to identify predilection sites of T. solium cysticercosis in pigs as well as to compare the lingual examination, carcass examination. Result: The prevalence rate of cysticercosis for lingual and carcass examination was 0.63%, 0.94% respectively. The incidence of cysticercosis was not significantly different (P&gt;0.05) between the Chitwan and Kathmandu valley and lingual (P&gt;0.05) and carcass examination (P&gt;0.05). Similarly the incidence of the disease was not significantly (P&gt;0.05) different among the slaughter slabs by lingual (P&gt;0.05) and carcass examination (P&gt;0.05). The common predilection sites of the cysts were skeletal muscle, diaphragm, heart, oesophagus and tongue. The sensitivity, specificity, positive and negative predictive values of Lingual examination, taking carcass examination, as gold standard was 50, 100, 100, 98.99 and 100, 82.65 respectively. Conclusion: Among the animal factor under study breed was found significantly (P&lt;0.05) associated with incidence of cysticercosis while the age and sex were not significant.
Reduction of CO<sub>2</sub> by Pyridine Monoimine Molybdenum Carbonyl Complexes: Cooperative Metal–Ligand Binding of CO<sub>2</sub> (2015)

[((Ar) PMI)Mo(CO)4 ] complexes (PMI=pyridine monoimine; Ar=Ph, 2,6-di-iso-propylphenyl) were synthesized and their electrochemical properties were probed with cyclic voltammetry and infrared spectroelectrochemistry (IR-SEC). The complexes undergo a reduction at more positive potentials than the related [(bipyridine)Mo(CO)4 ] complex, which is ligand based according to IR-SEC and DFT data. To probe the reaction product in more detail, stoichiometric chemical reduction and subsequent treatment with CO2 resulted in the formation of a new product that is assigned as a ligand-bound carboxylate, [( iPr 2PhPMI)Mo(CO)3 (CO2 )](2-) , by NMR spectroscopic methods. The CO2 adduct [( iPr 2PhPMI)Mo(CO)3 (CO2 )](2-) could not be isolated and fully characterized. However, the C-C coupling between the CO2 molecule and the PDI ligand was confirmed by X-ray crystallographic characterization of one of the decomposition products of [( iPr 2PhPMI)Mo(CO)3 (CO2 )](2-) .
Adherence of <i>Streptococcus pneumoniae</i> to Human Bronchial Epithelial Cells (BEAS-2B) (1998)

Pneumococcal adherence to alveolar epithelial cells and nasopharyngeal epithelial cells has been well characterized. However, the interaction of Streptococcus pneumoniae with bronchial epithelial cells has not been studied. We have now shown that pneumococci bind specifically to a human bronchial epithelial cell line (BEAS-2B cells). Pneumococci adhered to BEAS-2B cells in a time- and dose-dependent manner. These results suggest that the bronchial epithelium may serve as an additional site of attachment for pneumococci and demonstrate the utility of the BEAS-2B cell line for studying mechanisms of pneumococcal infection.

Favorable Propagation and Linear Multiuser Detection for Distributed Antenna Systems (2020)

Cell-free MIMO, employing distributed antenna systems (DAS), is a promising approach to deal with the capacity crunch of next generation wireless communications. In this paper, we consider a wireless network with transmit and receive antennas distributed according to homogeneous point processes. The received signals are jointly processed at a central processing unit. We study if the favorable propagation properties, which enable almost optimal low complexity detection via matched filtering in massive MIMO systems, hold for DAS with line of sight (LoS) channels and general attenuation exponent. Making use of Euclidean random matrices (ERM) and their moments, we show that the analytical conditions for favorable propagation are not satisfied. Hence, we propose multistage detectors, of which the matched filter represents the initial stage. We show that polynomial expansion detectors and multistage Wiener filters coincide in DAS and substantially outperform matched filtering. Simulation results are presented which validate the analytical results.
Universal fused floating-point dot-product unit (UFDP) (2013)

A universal floating-point fused dot-product (UFDP) unit is presented that is capable of performing floating-point multiplication and addition or subtraction operations on two pairs of data, floating-point multiply add operation on three data items, floating-point multiplication of two data items and floating-point addition or subtraction of two data items. The proposed UFDP unit could be used as the only floating-point primitive a processor needs, where it easily can replace a floating-point adder, multiplier, fused multiply-add and a fused dot-product unit. Due to the dominance of multiply-add and dot-product operations in audio and video processing algorithms this unit can lead to substantial performance enhancement. The synthesis results using 32nm industry standard-cell library shows that the proposed architecture occupies an area of approximately twice a basic floating-point multiplier, can perform all operations in less 160% of a basic floating-point operation and consumes 80% more than a basic floating-point multiplier.
Invasion and Metastasis (2007)

Abstract Cancer is usually diagnosed and treated when it is too late for local therapeutic strategies and most patients already harbour occult or overt metastasis. Metastatic dissemination can occur via lymphatic and vascular systems and represents the final stage of a disease process that can evolve over 5–20 years. Unrestrained growth by itself does not cause metastasis; additional genetic mutations over and above those that cause uncontrolled proliferation are needed. Less than 0.05% of circulating tumour cells are successful in initiation and development of a metastatic process. Metastatic distribution varies widely with histological type and anatomical location of the primary tumour. The organ preference for metastatic colonization is strongly influenced by communications between the circulating tumour cells and the target host tissue through a variety of molecular mechanisms. Moreover the presence of the new malignant cells within the invaded host tissue is associated with a local reorganization of the stroma, blood vessels, lymphatics, and epithelial morphology. Host cells contribute to enzymes and cytokines that promote tumour cell survival and invasion. Significant progress has been made in our understanding of the molecular cross‐talk between tumour cells and host cells at the invasion front. Several molecules including cytokines, growth and motility factors, matrix components, and degradative enzymes are thought to be required for the invasion process. Based on the cellular and extracellular context of the microenvironment, cytokines, stromal elements, and immune factors may promote or retard cancer pathogenesis. Invasion is dependent on the coordinated activity of a series of interacting proteins extending from the inside of the cell to the cell surface and the adjacent host cellular and extracellular microenvironment. Cellular adhesion, local proteolysis at the cell surface and of the extracellular matrix, and motility are the triad of necessary functions that mediate invasion. Normal tissue morphology and organ architecture are tightly regulated by a communication reciprocity between the tissue cells and the extracellular matrix and/or basement membrane. Instead of being autonomous, malignant cells communicate extensively with other cells and the extracellular matrix. Moreover, the transition from normal epithelium to invasive carcinoma is sturdily associated with activation of local host vascular elements, stromal fibroblasts, and matrix turnover. Locally activated vascular channels at the invasive edge of the tumour are highly permeable and offer a reduced barrier for intravasation. The transformation of epithelial cells into mesenchymal elements plays an important role in the promotion of the invasive phenotype. Tumour cells that successfully invade and metastasize are selected out because somatic genetic progression has resulted in an altered communication circuit that continues to call up and support invasion and survival.

Stability of the laser in situ keratomileusis corneal flap in rabbit eyes (2006)

In rabbits, LASIK corneal flaps were very resistant to high-speed wind trauma as early as 24 hours postoperatively. Flap stability was robust prior to the formation of collagen scar tissue, probably due to epithelial bridging at the edge of the flap and an osmotic gradient across the flap-stromal bed interface. Although this study used a rabbit model, it seems likely that both these flap adhesion mechanisms would also provide stability to the LASIK flap in humans.
Combustion System Performance and Field Test Results of the MS7001F Gas Turbine (1993)

This paper presents the results of the combustion system test of the MS7001F installed at the Virginia Power Chesterfield station. Tests of water and steam injection for NOx control were performed. Results of emissions, combustor dynamics, and combustor hardware performance are presented. Emissions test results include NOx, CO, unburned hydrocarbons, VOC, and formaldehyde levels. Combustor dynamic activity over a range of diluent injection ratios, and the performance of an actively cooled transition duct are also discussed. Combustion system mechanical performance is described following the first combustion system inspection.
Nonionic dimer: development and initial testing of an intrathecal contrast agent. (1982)

A nonionic dimer (DL-3-117) containing a novel substituent (D,L amino-threitol) was synthesized and tested as an intrathecal contrast medium. In the complement-mediated assay, the dimer was approximately half as inhibitory of hemolysis as metrizamide or iopamidol. The lethal dose (LD50) in protozoa was 320 mg I/ml for DL-3-117, 96 mg I/ml for metrizamide, and 101 mg I/ml for iopamidol. The intravenous LD50 of DL-3-117 in mice was 26 g/kg, and in rats it was 12.7 g/kg. The effective dose (ED50) of intradiencephalic injection in rats was 219 mg I/kg for DL-3-117, 61.9 mg I/kg for metrizamide, and 154.1 mg I/kg for iopamidol, which are significantly different. A dose of 300 mg I/kg injected into a permanently cannulated lateral ventricle produced neurofunctional deficits with all contrast media except DL-3-117, which scored equal to Ringer's solution. Metrizamide and iopamidol in the same model, adapted for aversion conditioning, induced aversion with 45 mg I/kg, while DL-3-117 did not condition the rats.
Efficient Generation of Delay Change Curves for Noise-Aware Static Timing Analysis (2002)

In this paper, we explore the concept of using analytical models to efficiently generate delay change curves (DCCs) that can then be used to characterize the impact of noise on any victim/aggressor configuration. Such an approach captures important noise considerations such as the possibility of delay change even when the switching windows of neighboring gates do not overlap. The technique is model-independent, which we demonstrate by using several crosstalk noise models to obtain results. Furthermore, we extend an existing noise model to more accurately handle multiple aggressors in the timing analysis framework. DCC results from the analytical approach closely match those from time-consuming SPICE simulations, making timing analysis using DCCs efficient as well as accurate.
VITAL Signs for Dietary Supplementation to Prevent Cancer and Heart Disease (2018)

The use of dietary supplement products is common in the United States. The National Health and Nutrition Examination Survey, conducted from 1999 through 2012, showed that more than half the adults in the United States consumed dietary supplements.1 In the past decade, the numbers of persons who supplemented their diets with fish oil increased by a factor of 10 and with vitamin D by a factor of 4.1 But any long-term health benefits from these products remain in doubt. Hence, the results from the Vitamin D and Omega-3 Trial (VITAL), a randomized, double-blind, placebo-controlled trial (with a two-by-two factorial design) . . .
Metabolism of Canthaxanthin, a Red Diketocarotenoid, by Chickens (1988)

Canthaxanthin, (4,4'-diketo-beta,beta-carotene), a red carotenoid used to extend the dominant wavelength of the yellow pigments in the skin and egg yolk of chickens, was fed (70 micrograms/g diet) to chicks depleted of normal tissue oxycarotenoids. High performance liquid chromatography analysis of tissues from such chicks revealed that a portion of canthaxanthin was reduced to 4-hydroxyechinenone (4-hydroxy-4'-keto-beta,beta-carotene) that in turn was reduced in part to isozeaxanthin (4,4'-dihydroxy-beta,beta-carotene). The alcohols thus formed were acylated in part to 4-hydroxyechinenone monoester and isozeaxanthin monoester and diester. Individual metabolites were identified by retention times, ratios A470/A430, and stopped-flow spectral analyses, which were identical in each case to authentic standards. Ratios of canthaxanthin to metabolites varied with the tissue, but in general metabolites were concentrated in the integument.
Embedded fiber-optic Fabry-Perot ultrasound sensor (1990)

A fiber-optic ultrasound sensor is presented. The sensor consists of a continuous length of single-mode optical fiber with a built-in Fabry-Perot interferometer. The acoustic pressure produces changes in the index of refraction along the interferometer cavity through the strain-optic effect, thus modulating the reflected power of the light propagating in the fiber. The dielectric internal mirrors that form the interferometer are fabricated by joining a fiber coating with a TiO(2) film at one end to an uncoated fiber by electric arc fusion splicing. Experimental results have been obtained for sensors embedded in plastic and graphite composite materials, using ultrasound waves in the range from 100 kHz to 5 MHz. Values for the optical phase shift amplitude as large as 0.5 rad were obtained at an acoustic frequency of 200 kHz for a 1.1-cm-long interferometer embedded in plastic.
TRIALS OF A SEMI-KAPLAN TOWBOAT PROPELLER (1990)
