Stability of queueing networks and scheduling policies (2002)

Usually, the stability of queueing networks is established by explicitly determining the invariant distribution. However, except for product form queueing networks, such explicit solutions are rare. We develop here a programmatic procedure for establishing the stability of queueing networks and scheduling policies. The method uses linear or nonlinear programming to determine what is an appropriate quadratic functional to use as a Lyapunov function. If the underlying system is Markovian, our method establishes not only positive recurrence and the existence of a steady-state probability distribution, but also the geometric convergence of an exponential moment. We illustrate this method on several example problems. For an open re-entrant line, we show that all stationary nonidling policies are stable for all load factors less than one. This includes the well known first-come-first-served (FCFS) policy. We determine a subset of the stability region for the Dai-Wang example (1991), for which they have shown that the Brownian approximation does not hold. In another re-entrant line, we show that the last-buffer-first-served (LBFS) and first-buffer-first-served (FBFS) policies are stable for all load factors less than one. Finally, for the Rybko-Stolyar example (1992), for which a subset of the instability region has been determined by them under a certain buffer priority policy, we determine a subset of the stability region.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Analysis of Stress Patterns in the Human Mandible (1975)

Replicas of a dentate human mandible were prepared in photoelastic resin material. They were positioned in a supporting frame by means of struts, representing the principal muscles of mastication. Occlusal loading was simulated, and the stresses generated within the models were examined by three-dimensional photoelastic stress analysis.
Comparison of EEG Synchrony Measures for Post-Stroke Neurorehabilitation (2018)

In post-stroke neurorehabilitation, the Functional Independence Measure (FIM) is a standard clinical scale used to assess patient's activities of daily living. Recently, we reported a new electroencephalography-based biomarker (the phase synchrony index) that correlates with this scale. For a more comprehensive evaluation, we compared three synchrony measures: phase synchrony index, phase lag index, and imaginary part of coherency. These synchrony measures showed a significant correlation with FIM motor subscores in the same frequency bands, but in different ways. These differences may be partly attributed to the susceptibility to the spurious synchrony by volume conduction effects and/or presence of the ceiling effect of synchrony measures. Our results suggest that we should select an appropriate synchrony measure as a biomarker for stroke recovery depending on the brain network of interest.
25 YEARS OF THE ISBS: A SILVER SALUTE TO SPORTS BIOMECHANICS RESEARCH PRESENTATIONS (2007)

The purpose of this report was to assemble a preliminary database of the research that has been presented at ISBS conferences over the past 25 years. Data were compiled
using available proceedings from previous years. Of interest were the volume of presentations, the distribution by continent, region, and nation, and the level of collaborative effort made by participating affiliates. A special focus was also placed on the last 5 conferences to demonstrate recent trends. With over 2,400 presentations, tremendous diversity has been seen so far, though it is recommended that concerted efforts be made to promote sports biomechanics in certain areas of the world, particularly South America, Africa, and Central and West Asia. Future research will determine the
best way to facilitate their future contributions to ISBS.
Self-diffusion of Er in pure and HfO/sub 2/-doped polycrystalline Er/sub 2/O/sub 3/ (1979)

Using a tracer sectioning technique, the self-diffusion of Er in pure and HfO/sub 2/-doped polycrystalline Er/sub 2/O/sub 3/ was measured at 1614 to 1900/sup 0/C. Up to approx. = 10 mol % HfO/sub 2/ dopant level, the Er self-diffusion coefficients followed a relation based on cation vacancies as the principal mobile defects present and available for cation diffusion. Above 10 mol % HfO/sub 2/, deviation from this relation occurred, apparently due to clustering of cation vacancies and oxygen interstitials around the dopant hafnium ions. The activation energy for the self-diffusion of Er in pure Er/sub 2/O/sub 3/ was 82.2 kcal/mol and increased with the HfO/sub 2/ dopant level present.
Crystallization and Melting Behavior in Polymer Blends (2016)

This chapter focuses on recent developments and progress related specifically to the crystallization and melting characteristics of polymer blends. It contains some basic aspects of crystallization kinetics, semicrystalline morphology, and melting behavior of miscible and immiscible polymer blends. It also includes important information from earlier books and articles and extends it to more recent achievements in this area. The addition of a second component to the pure polymer affects the crystallization and melting behavior of both polymer phases. These processes are complicated and influenced by parameters, such as the structures and molecular weights of both components, intermolecular interactions between them, blend compositions, equilibrium thermodynamics, and melt rheology. In the case of crystallizable/amorphous polymer blends, the amorphous component is rejected during crystallization of the crystallizable phase. In partially miscible polymer blends, two crystallization and demixing phenomena affect the phase transitions and the morphology, depending on the composition of the crystallizable component.
Cannabinoids for the treatment of neuropathic pain: clinical evidence. (2008)

Neuropathic pain is a worldwide epidemic that occurs in 3 to 8% of individuals in industrialized countries and is often refractory to existing treatments. Drugs currently available to target neuropathic pain are, at best, moderately effective and include antidepressants, gabapentin, NMDA receptor antagonists, as well as other anticonvulsants, all of which are limited by their adverse-effect profiles. Cannabinoid drugs are emerging as a promising class of drugs to treat neuropathic pain and have been tested for analgesic effects in a range of chronic pain conditions. Data show that cannabinoids are often effective in individuals with refractory pain receiving concomitant analgesic drugs. Clinical studies on cannabinoids for the treatment of neuropathic pain are reviewed, focusing on clinical trials published within the last five years. Data from large, well-controlled studies show that cannabinoids are moderately effective in reducing chronic pain and that side effects are comparable to existing treatments, suggesting that cannabinoids can play a useful role in the management of chronic pain. Like other drugs for neuropathic pain, cannabinoids have a dose titration that is limited by psychoactive side effects. The development of cannabinoid drugs to target neuropathic pain with improved therapeutic ratios will depend upon the development of cannabinoid treatments with reduced psychoactivity.
Separating the Power of Monotone Span Programs over Different Fields (2005)

Monotone span programs represent a linear-algebraic model of computation. They are equivalent to linear secret sharing schemes and have various applications in cryptography and complexity. A fundamental question regarding them is how the choice of the field in which the algebraic operations are performed affects the power of the span program. In this paper we prove that the power of monotone span programs over finite fields of different characteristics is incomparable; we show a superpolynomial separation between any two fields with different characteristics, solving an open problem of Pudlák and Sgall [Algebraic models of computation and interpolation for algebraic proof systems, in Proof Complexity and Feasible Arithmetic, DIMACS Ser. Discrete Math. Theoret. Comput. Sci. 39, P. W. Beame and S. Buss, eds., AMS, Providence, RI, 1998, pp. 279--296]. Using this result we prove a superpolynomial lower bound for monotone span programs for a function in uniform-${\cal N}C^2$ (and therefore in ${\cal P}$), solving an open problem of Babai, Gál, and Wigderson [Combinatorica, 19 (1999), pp. 301--319]. (All previous superpolynomial lower bounds for monotone span programs were for functions not known to be in ${\cal P}$.) Finally, we show that quasi-linear secret sharing schemes, a generalization of linear secret sharing schemes introduced in Beimel and Ishai [On the power of nonlinear secret-sharing, in Proceedings of the 16th Annual IEEE Conference on Computational Complexity, 2001, pp. 188--202], are stronger than linear secret sharing schemes. In particular, this proves, without any assumptions, that nonlinear secret sharing schemes are more efficient than linear secret sharing schemes.
Positional (supine dependent) obstructive sleep apnea (POSA) is uncommon in children (2016)

<b>Introduction:</b> Positional (supine) dependent obstructive sleep apnea (POSA) is a common condition in adults occurring in > 50% of adult OSA patients. Data regarding the effect of sleep position on the occurrence of respiratory events in children are limited and conflicting. <b>Aim:</b> To study the prevalence of POSA in children with moderate to severe OSA and correlate the data with upper airway findings. <b>Methods:</b> Sleep position was measured by means of a position sensor during full-night polysomnography. Obstructive apnea/hypopnea index (oAHI) was calculated for supine (oAHIsup) and non-supine (oAHInsup) positions. Time spent in each position was recorded. POSA is defined as oAHIsup > 2 X oAHInsup. Positional data were correlated to upper airway findings during drug induced sedation endoscopy (DISE). Data are presented as median and 25-75<sup>th</sup> percentile. <b>Results:</b> Data are available for 37 patients (15 girls, 22 boys), age 3.1 years (1.8-4.7), BMIz-score 0,29 (-0.96-1.3) with moderate to severe OSA: oAHI 14.3/hr (7.0-23.4). There was no significant difference between oAHIsup 13.6/hr (6.1-20.1) and oAHInsup 10.8 hr (6.6-19.2). Three patients had POSA, 2 of them had less than 5 minutes sleep in the non-supine position. There were no correlations between oAHIsup or oAHInsup and degree of adenoidal, tonsilar or tongue base obstruction during DISE. <b>Conclusions:</b> Positional (supine) dependent OSA is an uncommon condition in children with moderate to severe OSA. Further studies are needed to explore the prevalence of this condition in subgroups such as obese children or those with Down syndrome.
An overview of dialysis treatment in Juntendo Koto Geriatric Medical Center (KGMC) for the first five years of operation. (2008)

目的: 順天堂東京江東高齢者医療センターは2002年6月1日に開院し, 質と安全度の高い先端的な高齢者医療を提供してきた. 開院後5年間における血液浄化室にて施行した血液透析患者について解析し, 今後の高齢者に対する透析療法に活かすため, わが国全体の慢性透析療法の現況と比較検討した. 対象・方法: 2002年6月より2007年5月までの5年間に, 当センター血液浄化室にて透析療法を施行された慢性維持血液透析入院患者および維持血液透析療法に導入された入院患者計431名 (男性265名, 女性166名) を対象とした. 対象患者を1年毎に性別, 平均年齢, 新規血液透析導入患者数を統計学的に評価するとともに, 新規血液透析導入患者の原疾患および入院中の死亡原因について調査し, 日本透析医学会の統計調査と比較検討を行った. 結果: 毎年透析患者数は増加傾向で開業時と比較して直近で約3倍となっていた. 5年間の平均年齢は, 70.8歳 (男性69.4歳, 女性73.4歳) であった. また, 5年間で計89名 (男性61名, 女性28名) が新規導入され, 平均年齢は71.6歳 (男性66.7歳, 女性76.4歳) であった. 患者の原疾患は, 糖尿病性腎症46名 (51.7%), 腎硬化症17名 (19.1%), 慢性糸球体腎炎7名 (7.9%) であった. 当センター入院中に46名が死亡し, 原因として感染症が最も多く (14名), 死亡患者全体の30.4%を占めていた. 悪液質/尿毒症により死亡した5名の入院時平均血清アルブミン値は, 2.4g/dlと低下していた. 結論: 当センター血液浄化室にて透析療法を施行された患者は増加傾向であり, 2006年6月からの1年間では平均年齢73.6歳と全国と比較して7.2歳高齢であった. 原疾患も糖尿病性腎症が半数以上を占め, 急速進行性糸球体腎炎の比率も高いことは高齢化に起因すると思われる. 死亡原因としては感染症が最も多く, 患者の高齢化や糖尿病患者の割合が多く免疫不全により誤嚥性肺炎や敗血症に罹患しやすいためと考えられた. 悪液質/尿毒症による死亡者は全例が高齢で長期透析患者であり, 低アルブミン血症を伴っていたことから当センター入院中の高齢長期透析患者に対する適切な栄養管理および透析効率の確保が一層必要と思われる.
Regio- and Stereoselective Synthesis of 13β-Substituted-milbemycins, Including the 13β-Alkyl-milbemycins (1992)

The synthesis of 13β-substituted milbemycins including 13β-alkyl milbemycins was examined in some detail. After establishing the SN1 reaction as the prefered method of introduction of substituents at the 13β position, it was found that the optimal synthesis of 13β-ethyl-milbemycin A420B involves a novel syn 1,3 reaction of 15-chloro-Δ13,14-milbemycin A422B with triethyl aluminium. Another new alkylation reaction using a nickel or cobalt catalysed reaction of dialkyl zinc with 13β-bromo-milbemycin A414B, involving a radical intermediate, was developed. Biological results are discussed.
Tibial Fixation of Anterior Cruciate Ligament Allograft Tendons (2009)

This study demonstrated that not all tibial fixation devices are designed to adequately accommodate different types of anterior cruciate ligament allografts. Biomechanical evidence suggests that caution is warranted when using an Achilles allograft fixated solely with an interference device.
Single‐Chain Folding Nanoparticles as Carbon Nanotube Catchers (2018)

ABSTRACT This contribution describes a simple method for preparing polymeric nanoparticles using photodimerization of anthracene moieties on the side chain of terpolymers in dilute regime and transformation of obtained polymeric nanoparticles into pyrene functional nanoparticles via Menschutkin quaternization procedure. Subsequently, pyrene possessing polymeric nanoparticles are attached onto multiwalled carbon nanotube (MWCNT) surfaces by π–π stacking strategy. Gel permeation chromatography, thermal gravimetric analysis, ultraviolet–visible, and fluorescence spectroscopies are used to analyze modified nanoparticles and their precursors. Electron microscopy and dispersion studies show that pyrene‐modified polymeric nanoparticles are able to interconnect various CNTs. © 2018 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym.

Research Resource: Whole-Genome Estrogen Receptor α Binding in Mouse Uterine Tissue Revealed by ChIP-Seq (2012)

To advance understanding of mechanisms leading to biological and transcriptional endpoints related to estrogen action in the mouse uterus, we have mapped ERα and RNA polymerase II (PolII) binding sites using chromatin immunoprecipitation followed by sequencing of enriched chromatin fragments. In the absence of hormone, 5184 ERα-binding sites were apparent in the vehicle-treated ovariectomized uterine chromatin, whereas 17,240 were seen 1 h after estradiol (E₂) treatment, indicating that some sites are occupied by unliganded ERα, and that ERα binding is increased by E₂. Approximately 15% of the uterine ERα-binding sites were adjacent to (<10 kb) annotated transcription start sites, and many sites are found within genes or are found more than 100 kb distal from mapped genes; however, the density (sites per base pair) of ERα-binding sites is significantly greater adjacent to promoters. An increase in quantity of sites but no significant positional differences were seen between vehicle and E₂-treated samples in the overall locations of ERα-binding sites either distal from, adjacent to, or within genes. Analysis of the PolII data revealed the presence of poised promoter-proximal PolII on some highly up-regulated genes. Additionally, corecruitment of PolII and ERα to some distal enhancer regions was observed. A de novo motif analysis of sequences in the ERα-bound chromatin confirmed that estrogen response elements were significantly enriched. Interestingly, in areas of ERα binding without predicted estrogen response element motifs, homeodomain transcription factor-binding motifs were significantly enriched. The integration of the ERα- and PolII-binding sites from our uterine sequencing of enriched chromatin fragments data with transcriptional responses revealed in our uterine microarrays has the potential to greatly enhance our understanding of mechanisms governing estrogen response in uterine and other estrogen target tissues.
Q[sub 0] Degradation of LANL 700-MHZ [beta]=0.64 Elliptical Cavities and ANL 340 MHZ Spoke Cavities (2002)

The quality factor (Q{sub 0}) of most of the six LANL {beta} = 0.64 700-MHz 5-cell elliptical cavities starts to drop at E{sub acc} = 8-10 MV/m, which may be related to multipacting. Residual resistances of these cavities were measured to be 5.0-7.6 n{Omega}. The sensitivity of surface resistance to the external magnetic field was measured to be 0.22 n{Omega}/mG. Q disease tests have shown no significant Q{sub 0} degradation for both elliptical cavities and a spoke cavity with our 100 {micro}m BCP.
GaN/AlGaN multiple quantum wells on <i>a</i>-plane GaN pillars for stripe-geometry nonpolar ultraviolet light-emitting devices (2003)

We investigated the growth of GaN/Al0.20Ga0.80N multiple quantum wells (MQWs) on selective-area-grown a-plane GaN pillars over r-plane sapphire. In contrast to the MQWs grown on planar a-plane GaN templates, these GaN/Al0.20Ga0.8N MQWs on the pillars exhibited pit-free and atomically smooth surface morphology. Their structural quality and their UV emission (at 357 nm) increased with the underlying pillar height. The epitaxy of GaN/AlGaN MQWs on the selective-area-grown pillars is thus a promising and simple approach for fabricating stripe-geometry, high-efficiency, nonpolar UV emitters.
Amorphous Semiconductor‐Electrolyte Junction. A New Interpretation of the Impedance Data of Amorphous Semiconducting Films on Metals (1986)

Abstract On the basis of the theory of amorphous semiconductor Schottky barrier an equivalent electrical circuit of the amorphous oxide film/electrolyte interface is proposed.—The analytical expressions for the equivalent conductance and capacitance of the barrier are reported in the hypothesis of a constant density of states within the mobility gap.—According to this model, the semiconducting properties and the impedance behaviour at different frequencies of anodic oxide films on Niobium are interpreted by taking into account the amorphous nature of the films.—An explanation for the anomalous behaviour of the Mott‐Schottky plots usually observed with amorphous anodic oxide films is presented.—The possible extension of such a model to different metal/anodic oxide/electrolyte junctions is suggested.
147. Soporte mecánico circulatorio tras fallo primario del injerto como alternativa al retrasplante cardíaco (2012)

La prevalencia del fallo primario del injerto (FPI) varía entre 1,4–30,7% y es responsable del 40% de mortalidad hospitalaria. Ocasionalmente, se precisan medios de soporte hasta la recuperación o retrasplante. Analizar la utilidad de soportes mecánicos en pacientes que sufren FPI tras trasplante cardíaco. En nuestro centro se han implantado 6 dispositivos a 6 pacientes con FPI. Hemos realizado un estudio descriptivo de esta cohorte analizando las causas, complicaciones y resultados a corto-medio y largo plazo. La edad media fue de 43 ± 11,3 años (50% varones). Tres se trasplantaron en alarma 0. La edad de los donantes fue 35,6 ± 7,5. El tiempo de isquemia 193,8 ± 35 min y de circulación extracorpórea (CEC) 156,5 ± 39,8. Se realizó terapia antibiótica anticipada en todos los pacientes. Los 6 presentaron disfunción ventricular derecha grave y fracción de eyección del ventrículo izquierdo (FEVI) media de 38 ± 23,1% tras el procedimiento. Se implantaron 5 oxigenadores de membrana extracorpórea (ECMO) venoarteriales y 1 asistencia biventricular Levitronix Centrimag®. Se pudieron retirar todos los dispositivos por considerar que el 100% de los pacientes se habían recuperado del FPI (sin retrasplante) a los 6,8 ± 5,3 días del implante. Falleció el paciente que había sido portador de la asistencia biventricular a los 4 días de la retirada del soporte por sepsis. El resto fueron dados de alta a los 64 ± 10,9 días, permaneciendo estables tras un seguimiento de 341,4 ± 217,4 días, con un seguimiento acumulado de 1.707 días. El implante de asistencias en pacientes con FPI tras el trasplante supone un avance en el tratamiento de esta patología. Es una técnica rápida y segura que permite recuperar el órgano trasplantado.

Membership of the Committee is as follows: J. E. Church; W. W. Horner; A. F. Meyer; C. M. Saville; L. K. Sherman; Samuel Shulits; R. N, Towl; F. J. Veihmeyer; Robert E. Horton (Chairman). The Executive. Sub‐Committee consists of Messrs. Horner, Sherman, and the Chairman. A Special Sub‐Committee to deal with all phases of surface‐ and channel‐erosion, transportation, and sedimentation was appointed in 1938, consisting of R. N. Towl and Professor Samuel Shulits (Chairman). Meetings of the Advisory Committee have been held at Washington on an average of at least once a month during the past year. As a rule these meetings are attended only by members of the Executive Sub‐Committee. Thus far these members only have been provided with transportation. Other members of the Committee are kept in touch with the work by correspondence. In addition to these meetings various members of the Committee have inspected Soil Conservation Service field‐experiment research work accessible to them and have assisted and advised field‐men directly and by correspondence in carrying on their work. The Chairman has inspected the Watershed and Hydrologic Studies at Freehold, and the Soil and Water Conservation Experiment Stations at Marlboro and Beemerville, New Jersey, Marcellus, New York, and the Hydraulic Laboratory at Spartanburg, South Carolina. W. W. Horner has undertaken to follow closely the experimental work at Edwardsville, Illinois. In addition to other meetings, a meeting was held at Coshocton, Ohio, Experimental Watershed, May 2–3, 1938, attended by Messrs. Horner, Sherman, and the Chairman and by about one hundred other persons, including Dr. W. C. Lowdermilk, Chief of the Research Division, and also C. E. Ramser, of the Soil Conservation Service, who acted as Chairman. In addition there were present representatives of other United States Government bureaus interested in hydrologic research, including the United States Forest Service, United States Weather Bureau, and United States Geological Survey. In addition to a field‐inspection, a full day was spent in the discussion of problems and methodology of hydrologic research.
