A Pulsatile Control Algorithm of Continuous-Flow Pump for Heart Recovery (2012)

The intra-aorta pump is a novel continuous flow (CF) left ventricular (LV) device. According to literatures, the pulsatile flow LV device can provide superior LV unloading and circulatory support compared with CF LV assist devices at the same level of ventricular assist device flow. Therefore, a pulsatile control algorithm for the intra-aorta pump is designed. It can regulate the pump to generate pulsatile arterial pressure (AP) and blood flow. A mathematic model of the cardiovascular-pump system is used to verify the feasibility of the control strategy in the presence of LV failure. The surplus hemodynamic energy (SHE), pulsatile ratio (PR), and pulsatile attenuation index (PAI) are used to evaluate the pulsatility of AP and blood flow. The SHE is 8,012.0 ergs/cm(3) by using the pulsatile control strategy (PCS) compared with 5,630.0 ergs/cm(3) by failing heart without support. The PR is 0.302 in the PCS vs. 0.315 in failing heart without support. Meanwhile, the PAI is 85.9% in the PCS compared with 69.7% in failing heart without support. The results demonstrate that the presented control strategy can maintain the pulsatility of AP and blood flow. Moreover, the pulsatile controller provides notably LV unloading. To test the response of the controller to the change of blood demand of patients, another simulation is conducted. In this simulation, the peripheral resistance is reduced to mimic the status of a slight physical active; the Emax is increased to simulate the ventricular contractility recovery. The simulation results demonstrate that the proposed control strategy can automatically regulate the pump in response to the change of the parameters of the circulatory system. To test the dynamic character of the intra-aorta pump, an in vitro experiment is conducted on an in vitro experiment rig. The experimental results demonstrate that the intra-aorta pump can achieve the pulsatile pump speed calculated by the pulsatile controller. The PCS is feasible for the intra-aorta pump. As a key feature, the proposed control strategy provides adequate perfusion in response to the change of blood demands of patients, while restoring the pulsatility of AP and blood flow.
Dietary protein and chromium tripicolinate in Suffolk wether lambs: effects on production characteristics, metabolic and hormonal responses, and immune status. (1999)

Thirty-two Suffolk wether lambs were fed for 84 d in a 2 x 2 factorial experiment using two levels of dietary protein (9.0 to 12.1% CP, low protein, LP; or 12.8 to 14.4% CP, high protein, HP) and supplemental Cr (none, C; or 400 ppb Cr as chromium tripicolinate, Cr). At 14- to 21-d intervals, lambs were weighed, and jugular blood samples were collected. Mean ADG and carcass weight (P > .10) did not differ. In lambs fed HP, Cr reduced liver weight and increased kidney weight (P < .01). Lambs fed HP had elevated plasma urea N (PUN; P < .01) and albumin (P < .04). During an i.v. epinephrine challenge on d 43, plasma cortisol declined in lambs fed Cr (Cr x time, P < .03) and in lambs fed LP (CP x time, P < .001). An i.v. glucose tolerance test conducted 3 h later showed that supplemental Cr decreased glucose clearance rate in lambs fed HP (CP x Cr, P < .10) but not in lambs fed LP. On d 62, PUN was increased in lambs fed HP (P < .001) between 0 and 3 h postprandial, and there was a Cr x CP interaction (P < .04). Postprandial plasma NEFA declined with Cr vs C (Cr x time, P < .07) and with HP vs LP (CP x time, P < .10). By d 66, lambs fed Cr had an elevated (P < .03) blood platelet and fibrinogen content. Chromium increased erythrocyte count in lambs fed HP (Cr x CP, P < .08), and isolated peripheral lymphocytes had greater blastogenic response to 4 microg/mL of phytohemagglutinin (Cr x CP, P < .001). The lymphocyte response to pokeweed mitogen (.2 microg/mL) was reduced in lambs fed Cr (P < .10). In the present experiment, Cr supplementation had minimal and inconsistent effects on production and metabolic criteria of lambs.
Electronic structure ofThRu2Si2studied by angle-resolved photoelectron spectroscopy: Elucidating the contribution of U5fstates inURu2Si2 (2017)

The electronic structure of ${\mathrm{ThRu}}_{2}{\mathrm{Si}}_{2}$ was studied using angle-resolved photoelectron spectroscopy (ARPES) with incident photon energies of $h\ensuremath{\nu}=655$--745 eV. Detailed band structure and the three-dimensional shapes of Fermi surfaces were derived experimentally, and their characteristic features were mostly explained by means of band-structure calculations based on density-functional theory. Comparison of the experimental ARPES spectra of ${\mathrm{ThRu}}_{2}{\mathrm{Si}}_{2}$ with those of ${\mathrm{URu}}_{2}{\mathrm{Si}}_{2}$ shows that they have considerably different spectral profiles, particularly in the energy range of $1\phantom{\rule{4pt}{0ex}}\mathrm{eV}$ from the Fermi level, suggesting that $\mathrm{U}\phantom{\rule{4pt}{0ex}}5f$ states are substantially hybridized in these bands. The relationship between the ARPES spectra of ${\mathrm{URu}}_{2}{\mathrm{Si}}_{2}$ and ${\mathrm{ThRu}}_{2}{\mathrm{Si}}_{2}$ is very different from the one between the ARPES spectra of ${\mathrm{CeRu}}_{2}{\mathrm{Si}}_{2}$ and ${\mathrm{LaRu}}_{2}{\mathrm{Si}}_{2}$, where the intrinsic difference in their spectra is limited only in the very vicinity of the Fermi energy. The present result suggests that the $\mathrm{U}\phantom{\rule{4pt}{0ex}}5f$ electrons in ${\mathrm{URu}}_{2}{\mathrm{Si}}_{2}$ have strong hybridization with ligand states and have an essentially itinerant character.
Electron and hole in-plane mobilities in HgTe-CdTe superlattices (1992)

Using a recently developed formalism for free-carrier transport in semiconductor superlattices with interacting quantum wells, we have calculated in-plane mobilities for electrons and holes in HgTe-CdTe heterostructures. Details of the highly nonparabolic and anisotropic band structures are fully incorporated into the theory, and the previous treatment of interface roughness scattering in quasi-two-dimensional structures has been generalized to account for superlattices with significant interwell interactions. Our results accurately account for a number of distinctive features in the experimental data, and good agreement between theory and experiment is obtained.
Is soybean oil an effective repellent against Aedes aegypti? (2010)

Abstract Soybean oil (SO) is considered an active ingredient in commercial BiteBlocker™ insect-repellent products. Our objective was to test mechanisms by which SO exhibits repellency, using the yellow fever mosquito, Aedes aegypti (L.) (Diptera: Culicidae), as a representative blood-feeding insect. In dual-port glass-cage olfactometers, human hands treated with SO at various concentrations attracted as many mosquitoes as did untreated hands, indicating that SO has no long-range repellent effect. In contrast, hands treated with N,N -diethyl-3-methylbenzamide (DEET) attracted significantly fewer mosquitoes than did untreated control hands. In cage experiments, treating an area of a human forearm exposed to A. aegypti with SO provided no protection against bites, whereas treating it with DEET did. These results indicate that SO has no short-range or contact repellent properties. Both DEET and the BiteBlocker™ product conferred protection for periods similar to those previously reported. Based on our data, classification of SO as an active mosquito repellent should be reconsidered.
Survival Differences in Women and Men After Septal Myectomy for Obstructive Hypertrophic Cardiomyopathy (2019)

In this large cohort of surgical patients with obstructive HCM, we observed significant differences at clinical presentation between women and men, in that women were older and more symptomatic. However, after adjustment for important baseline prognostic factors, there was no survival difference after septal myectomy by sex. Improved care of women with obstructive HCM should focus on early identification of disease and prompt surgical referral of appropriate patients who do not respond to medical treatment.
Comparison of Urban Link Travel Time Estimation Models Based on Probe Vehicle Data (2010)

The information collected by probe vehicles on the urban signalized network is widely used for traffic monitoring. Traffic conditions could be inferred based on the data collected by these probe vehicles. In recent years, the attempts to estimate link travel time based on probe vehicle data (e.g. positions, time stamps and speeds) are arising. However, due to the low polling frequencies (e.g. 1min or 5min), travel times recorded by probe vehicles provide only partial link or route travel times. In this paper, a three-layer Artificial Neural Network (ANN) model is proposed to estimate the complete link travel time for each individual probe vehicle. The information including positions, time stamps and speeds is input into the model and the output is the complete link travel time. The model is evaluated using the data from vissim simulation model. The results are compared with those from Hellinga's model and distance-proportion model. The evaluation results show that the proposed ANN model performs much better than Hellinga's model and distance-proportion model both in undersaturated conditions and oversaturated conditions.
Active vibration suppression of a flexible structure using smart material and a modular control patch (2000)

This paper presents experimental results of vibration suppression of a flexible structure using smart materials and a miniaturized digital controller, called the modular control patch (MCP). The MCP employs a TI-C30 digital signal processor and was developed by TRW for the United States Air Force for future space vibration control. In this research, the MCP is used to implement different control algorithms for vibration suppression of a cantilevered aluminium beam. The beam is equipped with smart sensors and actuators, and both are made of piezoceramics. Positive position feedback (PPF) control, strain rate feedback (SRF) control and their combinations were implemented. Experiments found that PPF control is most effective for single-mode vibration suppression, and two PPF filters in parallel are most effective for multimode vibration suppression. Experiments also demonstrated the capacity of smart material being used as sensors and actuators for vibration suppression. The MCP was shown to be capable of implementing various real-time control laws.
Geo-Consistency for Wide Multi-Camera Stereo (2005)

This paper presents a new model to overcome the occlusion problems coming from wide baseline multiple camera stereo. Rather than explicitly modeling occlusions in the matching cost function, it detects occlusions in the depth map obtained from regular efficient stereo matching algorithms. Occlusions are detected as inconsistencies of the depth map by computing the visibility of the map as it is reprojected into each camera. Our approach has the particularity of not discriminating between occluders and occludees. The matching cost function is modified according to the detected occlusions by removing the offending cameras from the computation of the matching cost. The algorithm gradually modifies the matching cost function according to the history of inconsistencies in the depth map, until convergence. While two graph-theoretic stereo algorithms are used in our experiments, our framework is general enough to be applied to many others. The validity of our framework is demonstrated using real imagery with different baselines.

Numerical analysis of frequency chirp in strongly injection-locked semiconductor ring lasers (2014)

Frequency chirp simulations based on rate equation analysis are performed for strongly injection-locked ring lasers for applications in optical communication and rf photonics. Different scenarios are explored and compared, including weak injection of a single ring laser, strong injection of a single ring laser, and strong injection of cascaded ring lasers. Together with previously published results, these simulations confirm that the novel whistle-geometry ring laser scheme can provide, especially when modulation signal is applied to both ring lasers in the cascaded arrangement, a greatly improved performance in terms of modulation response and frequency chirp, and more flexibility in the design of ultrahigh speed transmitters.
“Mix of Mics”- Phenotypic and Biological Heterogeneity of “Multipotent” Muscle Interstitial Cells (MICs) (2012)

The capacity of adult skeletal muscle for regeneration appears to be limited, with progressive impairment in repair efficiency of injured muscles observed in chronic muscular disorders and during aging. While satellite cells, the committed adult muscle stem cells, are the main direct cell source supporting the regenerative potential of adult skeletal muscles, the characterization of the cell types and signals that constitute the functional "niche" of satellite cells is currently the object of intense investigation. Recent studies have identified a functional relationship between satellite cells and various cell types located in key anatomical position, such as the interstitium of skeletal muscles. This heterogeneous population of muscle interstitial cells (MICs) appears to retain an intrinsic multipotency within the mesodermal lineage, and their direct or indirect contribution to myofiber turnover, repair and degeneration has been suggested by many studies that will be reviewed here. Given the existing gap of knowledge on lineage identity and functional properties of MICs, their detailed characterization at the single cell level holds the promise to provide key insight into the composition of this heterogeneous population and the dynamic transition through distinct sub-populations in healthy, diseased and aging muscles. This review provides an overview of the results of various studies describing the phenotype and the function of cells isolated from skeletal muscle interstitium, and discusses the importance of single cell transcription profiling in order to decipher the functional and phenotypical heterogeneity of muscle interstitial cells (MICs).
Two novel 14-Epi-analogues of 1,25-dihydroxyvitamin D3 inhibit the growth of human breast cancer cells in vitro and in vivo. (2000)

The biological activity of two novel 14-epi-analogues of 1,25(OH)2D3, 19-nor-14-epi-23-yne-1,25(OH)2D3 (TX 522) and 19-nor-14,20-bisepi-23-yne-1,25(OH)2D3 (TX 527), is described. Both analogues were at least 10 times more potent than 1,25(OH)2D3 in inhibiting in vitro cell proliferation and had much lower in vivo calcemic effects than 1,25(OH)2D3. Treatment with 1,25(OH)2D3, TX 522, or TX 527 in vitro was accompanied by an accumulation of cells in the G1 phase of the cell cycle. Protein levels of cyclin C and cyclin D1 in in vitro cultures of MCF-7 cells were down-regulated to 50 and 30%, respectively, of control levels at 72 and 120 h after stimulation. Protein levels of p21 and p27 at 72 h were significantly enhanced by 1,25(OH)2D3 and TX 522 but surprisingly not by TX 527. The inability of TX 527 to up-regulate p21 seemed to be cell type specific because p21 was induced in other cell types. Diminished phosphorylation of the retinoblastoma protein after treatment with 1,25(OH)2D3, TX 522, or TX 527 may ultimately contribute to the growth inhibition caused by these compounds. According to the data presented, the induction of apoptosis seemed not to be a major mechanism responsible for the growth-inhibitory effect of 1,25(OH)2D3 and analogues. Both 14-epianalogues significantly retarded tumor progression (40% reduced compared with control mice) in an in vivo model of MCF-7 breast cancer cells established in nude mice. In conclusion, these novel analogues have the eligible profile to be tested as therapeutic agents for the treatment of hyperproliferative diseases such as breast cancer.
FORMOSA-B: A Boiling Water Reactor In-Core Fuel Management Optimization Package (1999)

The computational capability to determine optimal core loading patterns (LPs) for boiling water reactors (BWRs) given a reference control rod program has been developed. The design and fidelity of the reference BWR core simulator are presented. The placement of feed and reload fuel is solved by an adaptive optimization by simulated annealing (OSA) objective algorithm. Objective functions available for BWR fuel management are maximization of end-of-cycle core reactivity, minimization of peak linear power density, maximization of critical power ratio, maximization of region average discharge burnup, and minimization of total reload cost. Constraints include thermal and fuel exposure related limits and cycle energy production, when appropriate. The results presented demonstrate the utility of OSA to improve LPs in this highly nonlinear and constrained search space.
Taming Large Events: Optimal Portfolio Theory for Strongly Fluctuating Assets (1998)

We propose a method of optimization of asset allocation in the case where the stock price variations are supposed to have "fat" tails represented by power laws. Generalizing over previous works using stable Lévy distributions, we distinguish three distinct components of risk described by three different parts of the distributions of price variations: unexpected gains (to be kept), harmless noise inherent to financial activity, and unpleasant losses, which is the only component one would like to minimize. The independent treatment of the tails of distributions for positive and negative variations and the generalization to large events of the notion of covariance of two random variables provide explicit formulae for the optimal portfolio. The use of the probability of loss (or equivalently the Value-at-Risk), as the key quantity to study and minimize, provides a simple solution to the problem of optimization of asset allocations in the general case where the characteristic exponents are different for each asset.
Thermoviscous effects on acoustic scattering by elastic solid cylinders and spheres (1982)

This paper presents analytic solutions and numerical results of the scattering of plane sound waves from a thermoelastic circular cylinder and from a thermoelastic sphere in an infinite, thermoviscous fluid medium. The thermoelastic properties of the cylinder and the sphere and the viscosity and thermal conductivity of the surrounding fluid are taken into consideration in the solutions of the acoustic-scattering problems. The associated acoustic quantities, such as the acoustic-radiation force, the acoustic attenuation, and the acoustic-scattering pattern, are first derived in closed forms and then evaluated numerically for a given set of material properties. Numerical results show that increasing fluid viscosity tends to increase the magnitudes of the acoustic-radiation force, the acoustic attenuation, and the angular distribution of the scattering pattern. However, the opposite trends are observed when the fluid temperature increases. The plots of the acoustic attenuation coefficients versus the dimensionless wavenumber of the incident sound wave reveal oscillatory phenomena, which are caused by the resonant vibrations of the cylinder or the sphere.
The Yeast HAL2 Nucleotidase Is an in Vivo Target of Salt Toxicity (1996)

The yeast halotolerance gene HAL2 encodes a nucleotidase that dephosphorylates 3'-phosphoadenosine 5'-phosphate (PAP) and 3'-phosphoadenosine 5'-phosphosulfate (PAPS), intermediates of the sulfate assimilation pathway. This nucleotidase is inhibited by Na+ and Li+ but not by K+. Incubation of wild-type yeast cells with NaCl and LiCl, but not with KCl, increased intracellular PAP to millimolar concentrations. No depletion of the pool of adenine nucleotides (AMP, ADP, ATP) was observed. Other stresses such as heat shock or oxidative stress did not result in PAP accumulation. PAPS concentrations also increased during salt stress but remained lower than 0.5 microM. S-Adenosylmethionine concentrations decreased by 50%, reflecting inhibition of sulfate assimilation during salt stress. Salt-induced PAP accumulation was attenuated in a yeast strain overexpressing HAL2. This strain grew better than the wild type under salt stress. These results suggest that the cation sensitivity of the HAL2 nucleotidase is an important determinant of the inhibition of yeast growth by sodium and lithium salts. In addition to blocking sulfate assimilation by product inhibition of PAPS reductase, PAP accumulation may have other unidentified toxic effects.
Improving pentose fermentation by preventing ubiquitination of hexose transporters in Saccharomyces cerevisiae (2016)

Substitution of N-terminal lysine residues in the endogenous hexose transporters Hxt1 and Hxt36 that are subjected to catabolite degradation results in improved retention at the cytoplasmic membrane in the absence of glucose and causes improved xylose fermentation upon the depletion of glucose and when cells are grown in d-xylose alone.
Prevention of Arachnoiditis and Postoperative Tethering of the Spinal Cord with Gore-Tex Surgical Membrane: An Experimental Study with Rats (1998)

In the present study, Gore-Tex surgical membrane was a very good material for the surgical repair of spinal dural defects. Additional experimental studies are required to compare Gore-Tex membrane with autologous tissues.
Comparison of phase situation in recently prepared chiral, racemic and achiral anticlinic high tilted compounds (2005)

Homologous series of three ring esters (biphenylates and benzoates) – chiral (S), racemic (R,S) and achiral (either isopropyl or 4-heptyl chain) were tested by DSC, X-ray and electrooptic methods. It was found that in chiral, racemic and achiral homologous series with a 4-heptyl chain, the smectic A phase is a strongly tilted phase of de Vries type, and molecules in the anticlinic phase are highly tilted within the layers (up to 45°). The homologous series with an isopropyl chain gave a normal smectic A phase and low tilted synclinic or anticlinic phase. Chirality does not influence the smectic layer thickness or the molecular tilts in the smectic synclinic or anticlinic phase, but strongly influences the ability to form anticlinic order. The ability of the molecules to adopt anticlinic order is suppressed when a permanent helical structure or strong steric hindrance is absent.
A Simulation-Based Digital Twin for Model-Driven Health Monitoring and Predictive Maintenance of an Automotive Braking System (2017)

This paper describes a model-driven approach to support heat monitoring and predictive maintenance of an automotive braking system. This approach includes the creation of a simulation-based digital twin, or numerical model, that combines different modeling formalisms into an integrated model of the braking system that can be used for monitoring, diagnostics, and prognostics. The paper provides an overview of the basic models including Modelica models, reduced order models for various key components of the system model, and controls and sensor models. The Modelica models are implemented in the ANSYS Simplorer simulation to leverage existing modeling work and connections with other ANSYS finite element software to utilize reduced order models. The simulation results include both baseline results for the system and the results of injecting failures into the system for monitoring and predictive maintenance.
Differentiating recurrent tumor from radiation necrosis: time for re-evaluation of positron emission tomography? (1998)

Our data suggest that the ability of FDG PET to differentiate recurrent tumor from radiation necrosis is limited. Both false-positive and false-negative PET scan results contributed to unacceptably low sensitivity and specificity values.
