Potential game theoretic attitude coordination on the circle: Synchronization and balanced circular formation (2010)

In this paper we consider potential game theoretic attitude coordination. We especially focus on two ordered configurations: “synchronization” and “balanced circular formation”. We first show that both problems constitute potential games by employing some global and individual objective functions, and a learning algorithm called Restrictive Spatial Adaptive Play (RSAP) leads robots to the ordered configurations with high probability even in the presence of mobility constraints. We moreover show that the problem also constitutes a group-based potential game and convergence of distribution of actions to stationary one can be accelerated. Finally, the effectiveness of the schemes is demonstrated by simulation and experiments on a testbed.
Effectiveness of Growth Hormone–Releasing Hormone Agonists (GHRH-A) in Chronic Kidney Disease-Induced Heart Failure with Preserved Ejection Fraction (2020)

ABSTRACT Background Therapies that improve morbidity and mortality in heart failure with preserved ejection fraction (HFpEF) are lacking. Growth hormone releasing hormone analogues (GHRH-A) reverse fibrosis and improve cardiac function in ischemic and non-ischemic animal models. We tested the hypothesis that GHRH-A treatment ameliorates chronic kidney disease (CKD)-induced HFpEF in a large animal model. Methods Female Yorkshire pigs (n=16) underwent 5/6 nephrectomy via renal artery embolization, which induced HFpEF, and 12-weeks later received daily subcutaneous injections of GHRH-A (n=8) or placebo (n=8). Kidney function, renal and cardiac MRI, pressure-volume loops, and electrical stimulation were assessed at baseline, 12-weeks, and 16-18 weeks post-embolization. Results The CKD model was confirmed by increased creatinine and BUN. HFpEF was demonstrated at 12 weeks by maintenance of ejection fraction associated with increased left ventricular mass, relative wall thickening, end-diastolic pressure (EDP), end-diastolic pressure-volume relationship (EDPVR), and tau. After 6 weeks of treatment, diastolic function improved in the GHRH-A group, evidenced by normalization of EDP (p=0.03) associated with improved diastolic compliance as measured by EDP/EDV ratio (p=0.018). Conclusion A beneficial effect of GHRH-A in diastolic function was observed in a CKD large animal model that manifests the characteristics of HFpEF. These findings have important therapeutic implications for the HFpEF syndrome.
Mass, quark-number, andsNNdependence of the second and fourth flow harmonics in ultrarelativistic nucleus-nucleus collisions (2007)

We present STAR measurements of the azimuthal anisotropy parameter ${v}_{2}$ for pions, kaons, protons, $\ensuremath{\Lambda},\overline{\ensuremath{\Lambda}},\ensuremath{\Xi}+\overline{\ensuremath{\Xi}}$, and $\ensuremath{\Omega}+\overline{\ensuremath{\Omega}}$, along with ${v}_{4}$ for pions, kaons, protons, and $\ensuremath{\Lambda}+\overline{\ensuremath{\Lambda}}$ at midrapidity for Au+Au collisions at $\sqrt{{s}_{\mathit{NN}}}=62.4$ and 200 GeV. The ${v}_{2}({p}_{T})$ values for all hadron species at 62.4 GeV are similar to those observed in 130 and 200 GeV collisions. For observed kinematic ranges, ${v}_{2}$ values at 62.4, 130, and 200 GeV are as little as 10--15% larger than those in Pb+Pb collisions at $\sqrt{{s}_{\mathit{NN}}}=17.3$ GeV. At intermediate transverse momentum (${p}_{T}$ from 1.5--5 GeV/$c$), the 62.4 GeV ${v}_{2}({p}_{T})$ and ${v}_{4}({p}_{T})$ values are consistent with the quark-number scaling first observed at 200 GeV. A four-particle cumulant analysis is used to assess the nonflow contributions to pions and protons and some indications are found for a smaller nonflow contribution to protons than pions. Baryon ${v}_{2}$ is larger than antibaryon ${v}_{2}$ at 62.4 and 200 GeV, perhaps indicating either that the initial spatial net-baryon distribution is anisotropic, that the mechanism leading to transport of baryon number from beam- to midrapidity enhances ${v}_{2}$ or that antibaryon and baryon annihilation is larger in the in-plane direction.

Effective formulations of objective functions for optimizing U-shaped folded dipole antenna by PSO (2012)

In this paper, particle swarm optimization (PSO) is applied to optimize dimension parameters of U-shaped folded dipole antenna (UFDA) assumed to be used inside an USB dongle for WiMAX. By adopting effective formulations of two different objective functions to PSO, shapes of the ground plane and the antenna element are optimized respectively to achieve broadband characteristic of UFDA in each case.
Treatment of FL cells with neuraminidase stimulating the sensitivities to diphtheria toxin and ricin toxin [proceedings]. (1978)

A linear independence measure is given for the coordinates of algebraic points of abelian functions in two variables. From this an abelian analogue of the Franklin-Schneider theorem is deduced.
Mobile Point Defects and Atomic Basis for Structural Transformations of a Crystal Surface (1994)

Structural transformations on elemental semiconductor surfaces typically occur above several hundred degrees Celsius, and the atomic motions involved are extremely rapid and difficult to observe. However, on the (111) surface of germanium, a few lead atoms catalyze atomic motions so that they can be observed with a tunneling microscope at temperatures below 80 degrees C. Mass transport and structural changes are caused by the creation and propagation of both vacancy-like and interstitial-like point defects within the crystal surface. The availability of dangling bonds on the surface is critical. A detailed atomic model for the observed motions has been developed and is used to explain the structural phase transition Ge(111)-c(2x8) <--> 1x1, which occurs near 300 degrees C.
Development of a Polymer Gel System for Improved Sweep Efficiency and Injection Profile Modification of IOR/EOR Treatments (2014)

Abstract The existence of high-permeability features, such as fissures, fractures, and eroded-out zones, diminishes the sweep efficiency of any water, gas, or polymer flooding operation. Placing crosslinked conformance polymer gels or other types of blocking agents in injection and/or production wells can generate the necessary flow diversion for increasing the recovery factor of enhanced oil recovery/improved oil recovery (EOR/IOR) treatments. This paper evaluates a high-molecular-weight (HMW) organically crosslinked polymer (OCP) (referred to as HMW-OCP) gel system for such scenarios. This conformance technology is the result of crosslinking reactions between HMW polyacrylamide and polyethylenimine (PEI). The relatively medium viscosities of the fluids caused by the HMW of the components of the system allows for in-depth gel placement in fractures and high-perm channels, without invading the matrix of the rock. A low-molecular version of this polymer system has proven to successfully control water production in matrix applications. This HMW-OCP system gelation occurs gradually with time and temperature and can be designed to suit the need for short and long placement times. Optimization of gelation times using chemical activators and bimodal distribution of polymer molecular weights (MWs) is discussed. Fast hydration of the base polymer provides on-the-fly mixing capabilities. Also, the use of all liquid polymers and additives allows ease of transportation, handling, and storage and mixing of large volumes of material usually necessary for this type of treatment. Laboratory test results show long-term plugging capabilities, thermal stability, and fluid-loss control. Introduction Inadequate profile injection and sweep efficiency are key challenges when trying to achieve reasonable recovery factors with IOR/EOR treatments. Fractures, high-permeability channels, and other heterogeneities present in reservoirs are very likely to provide preferential paths of least resistance to the fluid being injected to sweep hydrocarbons causing premature injected-fluid breakthrough. A common way to mitigate this problem and to maximize the amounts of swept oil from the reservoir is to place sealants or blocking agents in such flow paths. Polymer gels and other types of conformance materials are permeability-reducing agents that can fill fractures and high-permeability channels at the injector or producing well to generate flow diversion and increase sweep efficiency. There are several technologies that can be used to reduce injected-fluid production and increase sweep efficiency in fractured reservoirs.Crosslinked polymer gels.In situ swellable particulate polymers (or preformed gel particles).Triggered in situ activation of nano-sized gel particle emulsions.Silicate systems.
Optically induced ferroelectric domain gratings in SBN: theory and applications to quasi-phase matching and optical data storage (2002)

Illuminating a photoconducting strontium barium niobate crystal with a low intensity optical standing wave generates dynamic as well as remnant polarization gratings. We study the kinetics of these gratings and present a thermodynamic model for the grating formation. Fundamentally, light induced space charge fields dynamically modify the positions of ions within the unit cell and tailor the electronic, optical, and acoustic properties of the material.
3D Roadmapping in neuroendovascular procedures - an evaluation (2010)

The 2D Roadmapping technique was introduced in the field of digital angiography more than a decade ago, and has become the standard used in all interventional procedures. This technique is based around the generation of a 2D projected image of the vessels, used for endovascular material guidance, thereby allowing accurate guidance.
Large negative and positive optical Goos–Hänchen shift in photonic crystals (2018)

Low-loss photonic crystal (PC) mirrors exhibit positive and negative Goos-Hänchen shift (GHS) due to the strong angular and wavelength dependencies of their reflected phase. This Letter demonstrates the existence of large positive and negative GHS in PC mirrors through theoretical, numerical, and experimental approaches. A simple algebraic relation shows that positive effective thickness yields positive (negative) GHS for resonances that blue (red) shift with angle, while the opposite is true for interfaces with negative effective thickness. Spatiotemporal coupled-mode theory demonstrates the above relation for simple systems with one or two resonance modes, and it also shows the existence of both positive and negative GHS. These effects are numerically and experimentally verified in complex PCs with several resonance modes.
Formation and Characterization of Ni Nanofiber Catalysts on Nickel Metallic Foam by Electrospinning Process (2014)

We report the fabrication of nickel nanofiber catalysts supported on nickel metallic foam using a modified electrospinning with a grounded rotor and sequential reduction process. The robust deposition of aligned Ni nanofibers with a uniform morphology on the highly porous surfaces of the metallic foam could be achieved by controlling electrospinning parameters such as applied voltage, tip-collector-distance (TCD), concentration of polymer, and humidity. The diameters of the obtained nanofibers decreased with increasing voltage and TCDs. The uniform and thinnest Ni nanofibers on the Ni foam were obtained at a humidity of less than 30%, 15 kV applied voltage, and 17 cm TCD when using a precursor composed of nickel nitrate salt and poly(vinyl) pyrrolidone. The Ni foam catalyst support exhibited the superior thermal conducting property than other supports of MgO-MgAl2O4, Al2O3, and SiC, enabling to a higher heat transfer during catalytic reaction. As a result, the Ni nanofiber catalyst with a high surface area and superior heat transfer performance, which is supported on the metallic foam, were successfully fabricated via a modified electrospinning for potential application of XTL process converting anything to liquids, such as for Gas-to-Liquid (GTL), Coal-to-Liquid (CTL), and Biomass-to-Liquid (BTL).

Uma proposta para detecção de erros grosseiros em balanços de massa de processos industriais (2011)

As plantas químicas modernas são compostas por diversas unidades industriais como reatores, colunas de destilação etc. que estão conectados por uma complexa rede de tubulações. Variáveis de processo (vazões mássicas, temperaturas) são regularmente usadas para controle e avaliação de desempenho dos processos industriais. É esperado que essas medições satisfaçam os balanços de massa e energia associadas a restrições industriais quando o mesmo encontra-se no estado estacionário. Infelizmente, medições industriais não são perfeitas, e, de fato, sujeito a erros aleatórios, e, possivelmente, erros grosseiros. Os erros grosseiros podem ser causados devido ao mau funcionamento dos instrumentos, ruídos, ou, até mesmo, vazamentos no processo. A detecção de erros grosseiros é de grande importância, pois invalida a base estatística dos procedimentos de reconciliação de dados devido aos dados corrompidos, além de ser a base para o processo de diagnóstico de falha em uma unidade industrial. _________________________________________________________________________________________ ABSTRACT: A modern chemical plant consists of a large number of process units such as reaction vessels, distillation columns, and so forth, which are interconnected together by a complicated network of streams. Measurements of mass flow rates, temperature, and so forth are routinely made for purpose of process control and process performance evaluation. These measurements are expected to satisfy mass and energy balance constraints associated with the process network when the process is in a steady state. Unfortunately, the process measurements data are never perfectly corrected and are in fact subject to random and possibly gross errors. Malfunctioning instruments, measurement biases and process leaks, could cause the gross errors. Detection of the gross errors is of great of importance, because, firstly, the presence of gross errors will corrupt the data reconciliation calculation and spread the errors over all relatively corrected data; secondly, it is the basis of process fault diagnosis.
Amino Acids and Peptides. XXVI. Laminin-Related Peptide Poly(Ethylene Glycol) Hybrids and Their Inhibitory Effect on Experimental Metastasis. (1995)

Laminin-related peptide poly(ethylene glycol) hybrid, Tyr-Ile-Gly-Ser-Arg-aminopoly(ethylene glycol) was prepared by the solution method and carboxylated poly(ethylene glycol)-Tyr-Ile-Gly-Ser-Arg was prepared by the solid phase method. Their inhibitory effects on experimental tumor metastasis were examined in mice. The inhibitory effect of Tyr-Ile-Gly-Ser-Arg was significantly potentiated by hybrid formation with poly(ethylene glycol) either at amino- or carboxyl terminals of the peptide. Of the hybrids, Tyr-Ile-Gly-Ser-Arg-amino(polyethylene glycol) #6000 hybrid exhibited about 10 times more potent anti-metastatic effect than the peptide itself. The inhibitory effect of a mixture of the carboxylated poly(ethylene glycol) hybrid and Arg-Gly-Asp-aminopoly(ethylene glycol) hybrid also exhibited an inhibitory effect.
Theory and in vitro validation of a new extracorporeal arteriovenous loop approach for hemodynamic assessment in pediatric and neonatal intensive care unit patients* (2008)

In vitro validation confirmed the ability of the ultrasound dilution technology to accurately measure small flows and volumes required for hemodynamic assessments in small pediatric and neonatal patients. Clinical studies are in progress to assess the reliability of this technology under different clinical situations.
Chronic ataluren (PTC124) treatment of nonsense mutation cystic fibrosis (2011)

In a subset of patients with cystic fibrosis (CF), nonsense mutations (premature stop codons) disrupt production of full-length, functional CF transmembrane conductance regulator (CFTR). Ataluren (PTC124) allows ribosomal readthrough of premature stop codons in mRNA. We evaluated drug activity and safety in patients with nonsense mutation CF who took ataluren three times daily (morning, midday and evening) for 12 weeks at either a lower dose (4, 4 and 8 mg·kg(-1)) or higher dose (10, 10 and 20 mg·kg(-1)). The study enrolled 19 patients (10 males and nine females aged 19-57 yrs; dose: lower 12, higher seven) with a classic CF phenotype, at least one CFTR nonsense mutation allele, and an abnormal nasal total chloride transport. Both ataluren doses were similarly active, improving total chloride transport with a combined mean change of -5.4 mV (p<0.001), and on-treatment responses (at least -5 mV improvement) and hyperpolarisations (values more electrically negative than -5 mV) in 61% (p<0.001) and 56% (p = 0.002) of patients. CFTR function was greater with time and was accompanied by trends toward improvements in pulmonary function and CF-related coughing. Adverse clinical and laboratory findings were uncommon and usually mild. Chronic ataluren administration produced time-dependent improvements in CFTR activity and clinical parameters with generally good tolerability.
Equipment (1995)

Because the objectives of seismic surveys vary tremendously, from surveys having very shallow objectives to those having deep objectives in difficult areas, the scale of seismic equipment varies. However, the concepts are generally the same and we will not discuss all the variations. Pieuchot (1984) along with Evenden and Stone (1971) provide the principal references for seismic equipment.
Neuroendocrine Dysfunction in Sleep Apnea: Reversal by Continuous Positive Airways Pressure Therapy* (1989)

We studied the effects of sleep apnea on neuroendocrine function in a cross-sectional study of 225 consecutive men undergoing sleep studies and in a longitudinal study of 43 men with severe obstructive sleep apnea before and after 3 months of successful treatment with nasal continuous positive airways pressure to eliminate upper airways obstruction. Blood samples were collected at 0600-0630 h on awakening for measurement of plasma insulin-like growth factor I (IGF-I), total and free testosterone, sex hormone-binding globulin (SHBG), LH, FSH, PRL, T4, T4-binding globulin, and cortisol. The plasma hormone levels were analyzed in relation to the severity of sleep apnea, as indicated by the desaturation index (the hourly rate of episodes of arterial oxygen desaturation greater than 4% of the stable baseline) and the mean minimal oxygen saturation during the desaturation episodes. In the cross-sectional study plasma IGF-I, free and total testosterone, and SHBG levels were significantly lower in relation to the severity of sleep apnea, whereas plasma LH, FSH, PRL, T4, T4-binding globulin, and cortisol were not. The decreases in plasma IGF-I and total and free testosterone were independent of the effects of aging and adiposity by covariance analysis. In the longitudinal study plasma IGF-I, total testosterone, and SHBG, but not free testosterone, significantly increased after 3 months of nasal continuous positive airways pressure treatment. We conclude that sleep apnea causes reversible neuroendocrine dysfunction in men, which is manifested by decreased plasma. IGF-I, testosterone, and SHBG levels. This neuroendocrine dysfunction is related to the severity of the sleep apnea, as indicated by the nadir levels of arterial oxygen desaturation and the rate of desaturation episodes. These hormonal measurements may provide biochemical markers for both the severity of sleep apnea and its response to therapeutic intervention. In addition, sleep apnea may be a previously unrecognized confounder of the neuroendocrine correlates of aging.
GATA6 is an astrocytoma tumor suppressor gene identified by gene trapping of mouse glioma model (2007)

Malignant astrocytomas are the most common and lethal adult primary brain tumor. Retroviral gene trapping of nontransformed neonatal astrocytes from a glial fibrillary acidic protein (GFAP):(V12)Ha-Ras murine astrocytoma model led to isolation of the transcription factor Gata6. Loss of Gata6 resulted in enhanced proliferation and transformation of astrocytes. Human malignant astrocytoma cell lines, explant xenografts, and operative specimens demonstrated loss of GATA6 expression. Loss-of-function GATA6 mutations with loss of heterozygosity of the GATA6 locus were found in human malignant astrocytoma specimens but not in lower-grade astrocytomas or normal adult astrocytes. Knockdown of Gata6 expression in (V12)Ha-Ras or p53-/- astrocytes, but not in parental murine or human astrocytes, led to acceleration of tumorgenesis. Knockin GATA6 expression in human malignant astrocytoma cells reduced their tumorgenic growth with decreased VEGF expression. Collectively, these data demonstrate that GATA6, isolated from a murine astrocytoma model, is a novel tumor suppressor gene that is a direct target of mutations during malignant progression of murine and human astrocytomas. This work also demonstrates the utility of random mutagenesis strategies, such as gene trapping, on murine cancer models toward discovery of novel genetic alterations in corresponding human cancers.
