Towards An 'All Speed' Unstructured Upwind Scheme (2009)

In the authors previous studies [1], a time-accurate, upwind finite volume method (ETAU scheme) for computing compressible flows on unstructured grids was proposed. The scheme is second order accurate in space and time and yields high resolution in the presence of discontinuities. The scheme features a multidimensional limiter and multidimensional numerical dissipation. These help to stabilize the numerical process and to overcome the annoying pathological behaviors of upwind schemes. In the present paper, it will be further shown that such multidimensional treatments also lead to a nearly all-speed or Mach number insensitive upwind scheme. For flows at very high Mach number, e.g., 10, local numerical instabilities or the pathological behaviors are suppressed, while for flows at very low Mach number, e.g., 0.02, computation can be directly carried out without invoking preconditioning. For flows in different Mach number regimes, i.e., low, medium, and high Mach numbers, one only needs to adjust one or two parameters in the scheme. Several examples with low and high Mach numbers are demonstrated in this paper. Thus, the ETAU scheme is applicable to a broad spectrum of flow regimes ranging from high supersonic to low subsonic, appropriate for both CFD (computational fluid dynamics) and CAA (computational aeroacoustics).
Worst-Case Identification under Binary-Valued Observations (2010)

This chapter focuses on the identification of systems where the disturbances are formulated in a deterministic framework as unknown but bounded. Different from the previous chapters, here the identification error is measured by the radius of the set that the unknown parameters belong to, which is a worst-case measure of the parameter uncertainties. By considering several different combinations of the disturbances and unmodeled dynamics, a number of fundamental issues are studied in detail: When only binaryvalued observations are available, how accurately can one identify the parameters of the system? How fast can one reduce uncertainty on model parameters? What are the optimal inputs for fast identification? What is the impact of unmodeled dynamics and disturbances on identification accuracy and time complexity?
Growth of nanostructured nonmetallic inorganic coatings obtained by nanoscale localization of high-energy flows at the boundary of the phase separation (2020)

We performed a mathematical analysis of the theory of collective microplasma processes in solutions and the basic equation for the growth of a nanostructured nonmetallic inorganic coating during the formation of a coating - a film on the surface of a material immersed in an electrolyte solution during nanoscale localization of high-energy flows at the phase boundary. The microplasma process is considered as a process of collective microplasma discharges. It is shown that this model allows one to relate the main physicochemical parameters of electrochemical and microplasma processes in electrolyte solutions: concentration, temperature, pulse duration, polarization voltage with the characteristics of the coating formation process, growth rate, thickness, size, and grain weight of the coating. The total current of microplasma discharges is limited by the current passing through the boundary immiscible layer.
Towards a dissipativity framework for power system stabilizer design (1996)

The paper describes a dissipativity-based framework for the study of low-frequency oscillations in power systems and for power system stabilizer design. This framework leads to a robust controller design formulation, amenable to both H/sub /spl infin// and QFT tools. An illustrating numerical example presents QFT based design for a widely used benchmark two area, four machine power system.
Synchronous primary cutaneous melanomas: a descriptive study of their clinical features, histology, genetic background of the patients and clinical outcomes (2022)

Synchronous melanomas are more frequent than previously reported and are more frequent in older patients compared to single melanomas. Moreover, these patients have a higher risk of developing a new primary melanoma during follow-up and have higher rates of germline susceptibility variants. Nevertheless, these findings were not associated with worse outcomes.
Economic Analysis of Thermal Solvent Processes (2006)

Abstract SAGD and CSS are the main commercial technologies used for in-situ recovery of bitumen in Alberta. Due to the increasing costs for energy (natural gas) and the increasing restrictions on fresh water usage, VAPEX and other technologies have been proposed as alternative technologies for heavy oil production. VAPEX uses a pair of horizontal wells, similar to SAGD, but uses a gaseous solvent, typically propane, to mobilize the oil. The Thermal Solvent process uses a light hydrocarbon solvent, injected into the upper will of a horizontal well pair. The action of the solvent is augmented by heating the wellbores, possibly by a steam loop. The Hybrid Solvent process injects light hydrocarbon solvent (propane) plus a modest amount of steam, sufficient to vaporize the solvent. Several scaled laboratory model experiments were designed to evaluate VAPEX and other solvent-based processes for recovery of heavy oil or bitumen. One experiment evaluated the VAPEX process in Athabasca UTF bitumen. Two experiments were completed to evaluate the Thermal Solvent Process. Two experiments were completed to evaluate a Hybrid Solvent process. All experiments were compared using a common set of economic assumptions. The economic results indicated that a hybrid process could be cost-competitive with SAGD for a 30 m thick Athabasca formation, and that the Thermal Solvent process could be competitive in certain thick heavy oil situations. Introduction Heavy oil and bitumen reservoirs may be immobile at reservoir temperature, or they may have some initial oil mobility and some reservoir drive energy. These reservoirs may contain dead oil, as in the case of Athabasca bitumen, or they may have some dissolved gas, as in the case of Cold Lake or Burnt Lake reservoirs. SAGD is the main commercial technology used for in-situ recovery for Athabasca reservoirs. Due to the increasing costs for energy and the increasing restrictions on fresh water usage, VAPEX has been proposed as an alternative technology for bitumen production. VAPEX uses a pair of horizontal wells, similar to SAGD, but uses a gaseous solvent, typically propane, to recover the oil. Experimental evaluation of VAPEX and related processes for mobile heavy oil recovery was assessed by Alberta Research Council in Reference 1. The VAPEX process may be augmented by adding heat. Heating of a horizontal wellbore will reduce viscosity sufficiently to produce a large increase in oil rate. The heat will also serve to initiate communication between the injector and the producer. The heat will serve to speed the diffusion of solvent into the oil. The combination of heated wellbores and VAPEX is known as the Thermal Solvent process. Again, a pair of horizontal wells is used, but the wells contain heating strings. This heat vaporizes the injected solvent. Solvent vapour moves to the oil interface at the edge of the vapour chamber and dissolves in the oil. The diluted oil is reduced in viscosity and flows down the edge of the vapour chamber to the production well. The vaporized solvent is driven out of the oil by the heat as it enters the production well.
Beta TiNbSn Alloys with Low Young&rsquo;s Modulus and High Strength (2005)

Young’s modulus and tensile strength were investigated in relation to phase transformation and microstructural changes occurring during cold rolling and subsequent heat treatment using β (Ti–35 mass%Nb)–4 mass%Sn and (Ti–35 mass%Nb)–7.9 mass%Sn alloys. Stress-induced α″ martensite is generated on cold rolling of (Ti–35Nb)–4Sn whose martensitic transformation start temperature is around room temperature. Young’s modulus in the rolling direction is lowered by the generation of stress induced α″ phase with preferred texture, while it is recovered by the reverse martensitic transformation to β at 523 K. The reverse transformation yields fine β grains which are elongated approximately along the rolling direction and have an average grain size in width of less than 1 μm. This fine microstructure leads to high strength over 800 MPa with keeping low static Young’s modulus of 43 GPa. In contrast, mechanical properties of (Ti–35Nb)–7.9Sn in which matensite is not stress-induced are not so significantly improved by cold rolling and heat treatment.
Repetition of Single Words and Nonwords in Alzheimer's Disease (1997)

Repetition of single words and pronounceable nonwords (pseudowords) was assessed in Alzheimer's Disease (AD) patients to evaluate how lexical phonological processing might be accomplished when semantic and conceptual knowledge is impaired. AD patients performed significantly worse than healthy elderly controls on all repetition tasks. However, repetition abilities and dementia severity were not correlated, and AD patients produced the same distribution of error types as controls. Furthermore, despite their semantic problems, AD patients, like controls, showed a significant advantage for repeating real words compared to pseudowords, even when repeating low frequency phonologically complex words whose meaning is not likely to have been retained. The results support the postulated existence of a lexical phonological system that is used to repeat both known and novel words and that processes linguistic information independent of its meaning.
A 90nm CMOS bio-potential signal readout front-end with improved powerline interference rejection (2009)

This paper describes a 90 nm CMOS low-noise low-power biopotential signal readout front-end (RFE). The front-stage instrumentation amplifier (IA) features a chopper; an AC-coupler and a novel chopper notch filter for minimizing the DC-offset; transistors' flicker noise and 50 Hz powerline interference concurrently. A noise-aware transistor selection (thin- and thick-oxide) in the IA enables a flexible tradeoff between noise and input impedance performances. The 2 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">nd</sup> stage is a spike filter clocked by a parallel use of two non-overlapping clock generators, effectively tracking and suppressing the chopper spikes. The last stage is a gain-bandwidth-controllable amplifier for boosting the gain and alleviating different bio-potential signal measurements through simple digital controls. Simulation results showed that the RFE is capable of tolerating a differential electrode offset up to plusmn50 mV, while achieving 140 dB CMRR and 51.4 nV/radicHz inputreferred noise density. The notch at 50 Hz achieves 41dB rejection. The entire RFE consumes 16.55 to 35.5 muA at 3V.
The economic cost of inadequate sleep (2018)

The financial and nonfinancial costs associated with inadequate sleep are substantial. The estimated total financial cost of $17.88 billion represents 1.55 per cent of Australian gross domestic product. The estimated nonfinancial cost of $27.33 billion represents 4.6 per cent of the total Australian burden of disease for the year. These costs warrant substantial investment in preventive health measures to address the issue through education and regulation.
Molecular and Electronic Structure of Two Linear Thiophenolate-Bridged Heterotrinuclear Complexes [LFeRuFeL]2+/3+ (L = 1,4,7-Tris(4-tert-butyl-2-mercaptobenzyl)-1,4,7-triazacyclononane) (2000)

The reaction of [FeIIIL] with [RuIICl2(dmso)4] in methanol under argon, affords, upon addition of NaPF6, brown crystals of [LFeRuFeL](PF6)2· 3 CH3OH (1). Its one-electron oxidation product [LFeRuFeL](PF6)3 (2) [L = 1,4,7-(4-tert-butyl-2-mercaptobenzyl)-1,4,7-triazacyclononane] was generated by using one equivalent of [NO]BF4. The crystal structure determination of [LFeRuFeL](BPh4)2· CH3CN · 3 (CH3)2CO shows that 1 contains a trinuclear, face-sharing thiolato-bridged dication. Mössbauer spectroscopy established that the oxidation state distribution of 1 can best be described by Fe2.5RuIIIFe2.5 and 2 by FeIIIRuIIIFeIII. Complex 1 possesses a diamagnetic (St = 0) and 2 an St = 1/2 ground state. The electronic structures of 1 and 2 are rationalized by an MO picture involving Fe–Ru metal-metal bonds of bond order 0.5 in both species. Complex 1 is formally a mixed valence compound with complete delocalization of the “excess electron” (class III).

Associations of Sleep-disordered Breathing and Insomnia with Incident Hypertension and Diabetes. The Hispanic Community Health Study/Study of Latinos (2020)

<b>Rationale:</b> Sleep disorders are associated with hypertension and diabetes, which are primary risk factors for cardiovascular diseases and mortality. It is important to understand these associations in Hispanic/Latino individuals, in whom cardiovascular death is the leading cause of mortality.<b>Objectives:</b> To investigate the prospective associations of sleep-disordered breathing (SDB) and insomnia with incident hypertension and diabetes among U.S. Hispanic/Latino people over 6 years of follow-up and to assess potential sex differences in these associations.<b>Methods:</b> Data from 11,623 Hispanic/Latino participants in the Hispanic Community Health Study/Study of Latinos (visit 1, 2008-2011; visit 2, 2014-2017) were analyzed using survey logistic regression models, adjusting for potential confounders.<b>Measurements and Main Results:</b> SDB (apnea-hypopnea index of 5 or more) and insomnia (Women's Health Initiative Insomnia Rating Scale of 9 or more) were measured at baseline. Incident hypertension (stage 2 or greater) and diabetes were defined according to national guidelines. In the target population, 52.6% were women, with a mean age of 41.1 ± 14.9 years at baseline. SDB was associated with 1.54 higher adjusted odds of incident hypertension (95% confidence interval [CI], 1.18-2.00) and 1.33 higher odds of incident diabetes (95% CI, 1.05-1.67) compared with no SDB. Insomnia was associated with incident hypertension (odds ratio, 1.37; 95% CI, 1.11-1.69) but not with diabetes. The association between insomnia and incident hypertension was stronger among men than among women.<b>Conclusions:</b> SDB was associated with incident hypertension and diabetes. Insomnia was associated with incident hypertension. These findings support the importance of sleep disorders as modifiable targets for disease prevention and reduction.
Perspectives of physicians on medical acupuncture in Lebanon: a preliminary study (2020)

Interest in acupuncture among physicians in Lebanon appears to be limited, based on the low response rate. Among respondents, physicians who had tried or referred patients for acupuncture appeared to be more well informed about different acupuncture styles.

Reactive Stepping After Stroke: Determinants of Time to Foot Off in the Paretic and Nonparetic Limb (2016)

Unique stroke-related impairments of dynamic balance control and limb-load asymmetry may differentially influence paretic and nonparetic reactive step TFO, in response to a loss of balance. The amplitude of the perturbation influences reactive step TFO in both limbs. The results of the current study have implications for the future development of standardized clinical assessment methodologies and training strategies to evaluate and remediate reactive stepping and reduce fall risk.Video Abstract available for more insights from the authors (see Supplemental Digital Content 1, http://links.lww.com/JNPT/A133).
A preliminary evaluation of the effects of primary and secondary radiation forces on acoustic contrast agents (1997)

Primary and secondary radiation forces result from pressure gradients in the incident and scattered ultrasonic fields. These forces and their dependence on experimental parameters are described, and the theory for primary radiation force is extended to consider a pulsed traveling wave. Both primary and secondary radiation forces are shown to have a significant effect on the flow of microbubbles through a small vessel during insonation. The primary radiation force produces displacement of microspheres across a 100 micron vessel radius for a small transmitted acoustic pressure. The displacement produced by primary radiation force is shown to display the expected linear dependence on the pulse repetition frequency and a nonlinear dependence on transmitted pressure. The secondary radiation force produces a reversible attraction and aggregation of microspheres with a significant attraction over a distance of approximately 100 microns. The magnitude of the secondary radiation force is proportional to the inverse of the squared separation distance, and thus two aggregates accelerate as they approach one another. We show that this force is sufficient to produce aggregates that remain intact for a physiologically appropriate shear rate. Brief interruption of acoustic transmission allows an immediate disruption of the aggregate.

Valence ionization energies of Ni(CN) 2? 4 , CO(CN) 3? 6 and Fe(CN) 4? 6 , studied by X-ray emission spectroscopy and ab initio molecular-orbital methods (1988)

The valence ionization energies of Ni(CN)2–4, CO(CN)3–6and Fe(CN)4–6have been measured using X-ray emission spectroscopy. Ab initio molecular-orbital calculations of these ionization energies have been carried out at various levels of approximation and reveal the importance of both the different relaxation and correlation energies associated with metal and ligand localized ionizations.

Structured covariance completion via proximal algorithms (2017)

This paper studies the interplay between dynamics and statistics of a stochastically driven dynamical system. Motivation is provided by applications in fluid flow modeling and control. In this context, second-order statistics around the mean velocity profile can be obtained, for a subset of variables, from experiments or numerical simulations. The basic idea is to determine a parsimonious perturbation of the generator of the linearized Navier-Stokes equations, together with directions of excitation sources, that can account for the observed statistics. This covariance completion problem is to determine minimum energy and low-rank perturbation of the linearized dynamics to reconcile them with the partially available second-order statistics - such models are valuable as tools for analysis and control purposes. The resulting optimization problem can be cast as a convex semidefinite program (SDP). However, generalpurpose SDP solvers cannot handle typical problem-sizes that are of interest in fluid flows. We develop customized algorithms that allow handling such covariance completion problems for substantially larger scales. These algorithms exploit the structure of the problem and utilize the method of multipliers and the proximal augmented Lagrangian method.
