Influence of Metal Screen Materials on 3-D Electromagnetic Field and Eddy Current Loss in the End Region of Turbogenerator (2012)

Since the structure of a large capacity turbogenerator is complex in the end region, accurate calculation about the leakage magnetic field becomes a key factor in the design. In this paper, a 330-MW level turbogenerator is electromagnetically analyzed and investigated with different metal screens in the end region. Its nonlinear transient electromagnetic field and eddy current loss were calculated by using the time step finite-element method (FEM). The influences of metal screen materials on the electromagnetic field and eddy current loss were compared and analyzed. All of these will contribute to the turbogenerator engineering design. Using the loss gained by the magnetic field calculation as a heat source, the thermal field of the end region with a copper screen was calculated. Compared with the test data, the calculated temperature results match well with the measured data.
Variation in the reporting of elective surgeries and its influence on patient safety indicators (2021)

Abstract Background US hospital safety is routinely measured via patient safety indicators (PSIs). Receiving a score for most PSIs requires a minimum number of qualifying cases, which are partly determined by whether the associated diagnosis-related group (DRG) was surgical and whether the surgery was elective. While these criteria can exempt hospitals from PSIs, it remains to be seen whether exemption is driven by low volume, small numbers of DRGs, or perhaps, policies that determine how procedures are classified as elective. Methods Using Medicare inpatient claims data from 4,069 hospitals between 2015 and 2017, we examined how percentages of elective procedures relate to numbers of surgical claims and surgical DRGs. We used a combination of quantile regression and machine learning based anomaly detection to characterize these relationships and identify outliers. We then used a set of machine learning algorithms to test whether outliers were explained by the DRGs they reported. Results Average percentages of elective procedures generally decreased from 100% to 60% in relation to the number of surgical claims and the number of DRGs among them. Some providers with high volumes of claims had anomalously low percentages of elective procedures (5% – 40%). These low elective outliers were not explained by the particular surgical DRGs among their claims. However, among hospitals exempted from PSIs, those with the greatest volume of claims were always low elective outliers. Conclusion Some hospitals with relatively high numbers of surgical claims may have classified procedures as non-elective in a way that ultimately exempted them from certain PSIs.
Deviations from Ideality in Mixtures of Two Ionic Liquids Containing a Common Ion (2005)

Excess molar volumes of six binary mixtures composed of two ionic liquids of the 1-methyl-3-alkyl-imidazolium bis(trifluoromethylsulfonyl)amide family -- ([C(m)()mim] + [C(n)()mim])[NTf(2)] with n and m ranging from 2 to 10 -- were measured for several compositions at 298 and 333 K. Similarly, three other binary systems containing [C(4)mim](+) (1-methyl-3-butylimidazolium) as a common cation have been studied: [C(4)mim]([NTf(2)] + [PF(6)]), [C(4)mim]([NTf(2)] + [BF(4)]) and [C(4)mim]([BF(4)] + [PF(6)]). Thus, the mixing process of two distinct ions of equal sign embedded in a constant field network of a given counterion was analyzed. All systems exhibit small, positive V(E) values of the order of a few tenths of cm(3) mol(-1), which are essentially temperature and pressure independent. The results show additive trends, for instance, the V(E) values become larger as the difference between the alkyl chain lengths of the two cations increases. The Flory theory of mixtures provides a useful, semiquantitative correlation between the excess volumes and excess enthalpies in these systems, allowing for comparison with analogous results obtained within the linear primary alcohols.
Volumetric self-sampling of cervicovaginal fluid to determine potential fertility: a multicentre pre-effectiveness study of the Rovumeter (1997)

The aim of this study was to assess how effectively the Rovumeter, designed for the volumetric self-sampling of cervicovaginal fluid (CVF), can be used to locate the minimum period of potential fertility (PPF) during ovulatory cycles. A multicentre, prospective study was undertaken of volunteers (attending natural family planning clinics) over three consecutive, apparently normal, menstrual cycles. All women collected daily samples of early morning urine and CVF and recorded the volumes (to the nearest 1.0 and 0.1 ml respectively). The concentrations of oestrone glucuronide (EG), luteinizing hormone (LH) and pregnanediol glucuronide (PG) were measured in all samples of early morning urine by immunoassay. A preliminary data set was used to optimize an algorithm to detect the start and end of potential fertility from the volumes of CVF. The end-points used were the normality of each menstrual cycle from its length, the length of luteal phase, and concentrations of EG, LH and PG, the start and end days of potential fertility from CVF volumes, and the minimum PPF, which was defined as the day of the LH peak minus 3 to day plus 2 inclusive. Overall, 72 women (median age 30 years, range 24-38) were recruited from three centres (23 from Birmingham, 24 from Milan, 25 from Santiago) and contributed data from 235 menstrual cycles (median length 28 days, range 23-44). The urinary LH peak was identified in 228 cycles (97%; median time, day 15 from day 1 of last menses, with range day 10 to day 35). The use of the Rovumeter gave start and end signals of potential fertility during 138 cycles (59%). The median length of the derived PPF was 8 days (range 4-18). The signals covered the defined, minimum PPF in 113 cycles [i.e. 50% of those with an LH peak; range 28% (Milan) to 62% (Birmingham)]. Overall 16/72 women (22%) had successful tests over three consecutive menstrual cycles [range 2/24 (8%; Milan) to 8/23 (35%; Birmingham)]. We conclude that signals from daily changes in the volume of CVF as determined by the use of the Rovumeter consistently locate the minimum period of potential fertility in only a small proportion of women.
Microfluidic MEMS for semiconductor processing (1998)

The advent of MEMS (microelectromechanical systems) will enable dramatic changes in semiconductor processing. MEMS-based devices offer opportunities to achieve higher performance and functionality, at lower cost, with decreased size and increased reliability. In this work, we describe the achievement of several important devices for use in the semiconductor equipment industry. They include a low-flow mass flow controller, a high-precision pressure regulator, and an integrated gas panel. Compared to current technology, the devices are ultra-small in size, thus minimizing dead volumes and gas contact surface areas. With wettable surfaces comprised of ceramic and silicon (or, silicon coated with Si <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</inf> N <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">4</inf> or SiC), they are resistant to corrosion, and generate virtually no particles. The devices are created from modular components. The science and technology of these components will be detailed. The modules examined are: normally-open proportional valves; normally-closed, low leak-rate shut-off valves; critical orifices (to extract information of flow rate); flow models (to extract flow rate from pressure and temperature information); silicon-based pressure sensors; and, the precision ceramic-based packages which integrate these modules into useful devices for semiconductor processing. The work finishes with a detailed description of the low-flow mass flow controller.
Resonant Microwave Effect on Locally Fixed Yeast Microcolonies (1989)

The microwave influence on the growth of yeast cells is studied in a novel experimental set-up designed to observe individual cells growing for several division cycles. The results are in accordance with resonant microwave-induced growth stimulation as observed in our earlier set-up where the turbidity of a stirred suspension of cells was used as the measure of growth. The new experimental set-up is suited to decide on the proposed triplet mechanism of resonant microwave biological effects.
A Possible Intrinsic Fluence-Duration Power-Law Relation in Gamma-ray Bursts (2000)

We argue that the distributions of both the intrinsic fluence and the intrinsic duration of the gamma-ray emission in gamma-ray bursts from the BATSE sample are well represented by log-normal distributions, in which the intrinsic dispersion is much larger than the cosmological time dilatation and redshift effects. We perform separate bivariate log-normal distribution fits to the BATSE short and long burst samples. The bivariate log-normal behavior results in an ellipsoidal distribution, whose major axis determines an overall statistical relation between the fluence and the duration. We show that this fit provides evidence for a power-law dependence between the fluence and the duration, with a statistically significant different index for the long and short groups. We discuss possible biases which might affect this result, and argue that the effect is probably real. This may provide a potentially useful constraint for models of long and short bursts.
Atherosclerosis as an Inflammatory Process (1985)

In this brief review, we have addressed the roles of the monocyte-macrophage in atherogenesis, with emphasis on the recruitment to the arterial wall. We have presented summary data on the SMC-derived chemoattractant protein and also on the temporal evolution of monocyte-derived macrophages into cholesteryl ester-rich foam cells. The concept of atheroma as an inflammatory process has also been discussed.

La investigación privada de la CEO (2007)

Cuando la nueva CEO Cheryl Tobin llega a Hammond Aerospace, percibe un ligero aroma a corrupcion. Pero si su predecesor rompio las reglas, su equipo ejecutivo guarda silencio. Temerosa de danar reputaciones sin datos solidos, duda en hacer publicas su preocupaciones. ?Se requiere una investigacion privada? Cinco expertos comentan este caso ficticio escrito por Finder, un escritor superventas de thrillers corporativos.
Harry Brandon, especialista internacional en inteligencia de negocios, ayuda a las empresas a llegar al fondo de asuntos como este. La evaluacion meticulosa de documentos y el manejo cuidadoso de los informantes internos puede ser crucial, dice, para determinar si se ha violado la ley. En un cuarto de los casos no hay nada bajo el humo; en el resto, encuentra llamas.
Christopher E. Kubasik y James B. Comey, de Lockheed Martin aconsejan a Cheryl desde el mundo real del sector aeroespacial: primero, que acuda al vicepresidente de etica o, si no lo hay, a las personas que dirigen la organizacion de auditorias internas. Donde sea que esto lleve a Cheryl, su primera prioridad deberia ser enviar un mensaje claro de que los actos ilicitos no seran ignorados.
Eric A. Klein, un abogado de Katten Muchin Rosenman que asesora a empresas y a sus consejos de administracion, tiene una regla cardinal: gestione el proceso, no la crisis. Dice que Cheryl deberia descubrir como se manejaron previamente los problemas eticos en la empresa. Tambien deberia medir sus responsabilidades legales, sopesando los costos y beneficios potenciales de una investigacion.
William J. Teuber, Jr., de EMC, dice que Cheryl deberia aprovechar la sabiduria del presidente del consejo, quien acaba de reclutarla. Si se requiere una investigacion, Teuber sostiene que abogados externos son los mas indicados para el trabajo y que Cheryl no deberia seguir investigando ella misma.
[Intra-arterial infusion chemotherapy for advanced or recurrent breast cancers]. (1995)

Ideally, in preoperative intra-arterial infusion chemotherapy (regarding advanced breast cancer) is to obtain the most significant effects concerning histological features. Intra-arterial infusion chemotherapy using epirubicin (EPI), used in conjunction with daily doses of 1,200 mg medroxyprogesterone acetate (MPA), have recently been performed. This procedure has shown remarkable histological effects in the metastatic lymph nodes as well as in the primary lesions. These results were especially remarkable in the patients who were administered MPA (daily) two weeks prior to EPI infusion. These patients showed a complete disappearance of tumor cells. The results were interesting in view of the mechanism of action. Intra-arterial infusion chemotherapy combined with MPA may also be valuable in treating metastatic liver tumors and recurrent lesions in the regional lymph nodes such as supraclavicular tumors. A high response rate was obtained in the chemo-endocrine therapy when combined with MPA as a pretreatment. Thus, MPA may be expected to be available as a systemic therapy, too. In the future, a new development in the field of intra-arterial infusion chemotherapy may be achieved by utilizing a combination of angiogenesis inhibitors and peripheral blood stem cell transplantation.
A Circulating β<sub>2</sub>-Microglobulin Intermediate in Hemodialysis Patients (2009)

This study demonstrated that two or three conformational isomers of beta(2)m were probably ubiquitously recognized in human serum. Though no progressive increase in serum I-beta(2)m concentration could be found along with HD, this study shows a significantly poor removal of I-beta(2)m in comparison to N-beta(2)m in patients receiving ongoing dialysis treatment, even with online HDF.
Joint multiuser downlink beamforming and admission control in heterogeneous networks (2014)

This work studies the problem of joint multiuser downlink beamforming and admission control in multiple-input multiple-output (MIMO) heterogeneous networks. Considered is a network where a newly deployed femtocell base-station (FBS) has the coverage overlapped with that of an existing macrocell base-station (MBS). Our design objective is to serve as many femto-users (FUEs) as possible at their quality-of-service (QoS) requirements while maintaining the QoS requirements at the macro-users (MUEs). In the first part of this work, we consider the joint downlink beamforming and admission control problem as a joint optimization problem, which can be solved in a centralized manner with full coordination between the MBS and the FBS. In the second part, we propose a distributed algorithm in performing joint downlink beamforming and admission control at the femtocell with only limited MBS-FBS coordination. Specifically, after acquiring certain design parameters from the MBS, the FBS unilaterally determines its beamforming and admission control strategy while coordinating its induced interference to the macrocell. We then prove that the distributed algorithm will converge to a fixed-point where the QoS at the MUEs and admitted FUEs is guaranteed. Simulation results show that the distributed algorithm performs as well as the centralized one in terms of number of FUEs served with only a small penalty on the power usage at the MBS and the FBS.
A multi-version approach to conflict resolution in distributed groupware systems (2002)

Groupware systems are a special class of distributed computing systems which support human-computer-human interaction. Real-time collaborative graphics editors allow a group of users to view and edit the same graphics document at the same time from geographically dispersed sites connected by communication networks. Resolving conflict access to shared objects is one of the core issues in the design of this type of system. This paper proposes a novel distributed multi-version approach to conflict resolution. This approach aims to preserve the work concurrently produced by multiple users in the face of conflicts, and to minimize the number of object versions for accommodating combined effects of conflicting and compatible operations. Major technical contributions of this work include a formal specification of a unique combined effect for any group of conflicting and compatible operations, a distributed algorithm for incremental creation of multiple object versions, and a consistent object identification scheme for multi-version and multireplica graphics editing systems. All algorithms and schemes preserved in this paper have been used in the GRACE (Graphics Collaborative Editing) system implemented in Java.
Securing infrastructure from high explosive threats (2009)

Lawrence Livermore National Laboratory (LLNL) is working with the Department of Homeland Security's Science and Technology Directorate, the Transportation Security Administration, and several infrastructure partners to characterize and help mitigate principal structural vulnerabilities to explosive threats. Given the importance of infrastructure to the nation's security and economy, there is a clear need for applied research and analyses (1) to improve understanding of the vulnerabilities of these systems to explosive threats and (2) to provide decision makers with time-critical technical assistance concerning countermeasure and mitigation options. Fully-coupled high performance calculations of structural response to ideal and non-ideal explosives help bound and quantify specific critical vulnerabilities, and help identify possible corrective schemes. Experimental validation of modeling approaches and methodologies builds confidence in the prediction, while advanced stochastic techniques allow for optimal use of scarce computational resources to efficiently provide infrastructure owners and decision makers with timely analyses.

Imaging and image restoration of lens-combined modulated wavefront coding (2016)

In this paper, it presents a new wavefront coding (WFC) technology that we call lens-combined modulated wavefront coding (LM-WFC). Based on the LM-WFC design method, we establish a large depth of field and large aperture system. Simulation results indicate that the modulation transfer function of the system has a defocus invariant characteristic, which all typical WFC systems have, with a large depth of field. Experimental results for comparing the LM-WFC imaging system and a traditional imaging system are presented. The comparative results demonstrate that the LM-WFC system has an imaging performance invariant over a wide depth of field range.
Through a lens sharply [FluidFocus lens (2004)

Philips Research Laboratories has developed the FluidFocus lens that is ideal not only for camera phones but also in products whose design constraints demand a tiny but capable optical system. Like the lens of the human eye, the FluidFocus lens varies its focus by changing shape rather than by changing the relative positions of multiple lenses. The lens uses electrostatic forces to alter the shape of a drop of slightly salty water inside a glass cylinder 3 mm in diameter and 2.2 mm long. One end of the cylinder points toward the image plane while the other is directed at the subject being imaged. The cylinder containing the water drop is filled with oil. Around the inside walls of the cylinder is a water-repellent Teflon-like coating, and behind this coating is an electrode. Basically, the water and the oil makes up the lens, and the shape of the interface between the two determines its focal length. The optical power of the lens that forms at the surface between the oil and the water depends on the curvature of the meniscus and the difference between the refractive indices of the oil and water.
Experimental and computational studies on collective hydrogen dynamics in ammonia borane: Incoherent inelastic neutron scattering (2009)

Incoherent inelastic neutron scattering is used to probe the effects of dihydrogen bonding on the vibrational dynamics in the molecular crystal of ammonia borane. The thermal neutron energy loss spectra of (11)B enriched ammonia borane isotopomers ((11)BH(3)NH(3), (11)BD(3)NH(3), and (11)BH(3)ND(3)) are presented and compared to the vibrational power spectrum calculated using ab initio molecular dynamics. A harmonic vibrational analysis on NH(3)BH(3) clusters was also explored to check for consistency with experiment and the power spectrum. The measured neutron spectra and computed ab initio power spectrum compare extremely well (50-500 cm(-1)). Some assignment of modes to simple harmonic motion, e.g., NH(3) and BH(3) torsion in the molecular crystal is possible, and it is confirmed that the lowest modes are dominated by collective motion. We show that the vibrational dynamics as modeled with ab initio molecular dynamics provides a more complete description of anharmonic and collective dynamics in the low frequency region of the inelastic incoherent neutron scattering spectra when compared to the conventional harmonic approach.
