Overflow analysis for finite waiting room systems (1990)

A system of multiple primary queues with finite waiting rooms, where blocked jobs are allowed to overflow onto a common secondary queue, also with finite waiting room, is considered. Poisson arrivals and exponentially distributed service times, possibly different ones, are assumed at each primary service facility. Service facilities consist of a single server or multiple servers. Based on a simple iterative expression for the Laplace-Stieltjes transform of the interoverflow time distribution, the peakedness of the overflow process from primary queues is studied as a function of the number of primary servers and buffers as well as the original primary load. Behaviors and relations are identified for extreme cases (low offered load or large waiting rooms) and illustrated with examples. An approximation consisting of a natural extension of Hayward's formula to finite waiting room systems is proposed to estimate the blocking seen by the overflow traffic offered to the secondary service facility. Numerical examples covering a wide range of systems show that the approximation is good over a wide range of loads for systems with a single primary queue, as well as at high load for systems with multiple primary queues.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Migration and Diffusion of Finishing Agents in Drying (1968)

Large increases in crease-recovery angles may be obtained if the drying of methylol- melamine-impregnated cotton and rayon fabrics is interrupted at 34% and 40% regain, respectively, and the drying is completed slowly or after a delay of some hours. Resistance to abrasion is not correspondingly reduced, but the tensile strength of cotton was somewhat lower. This effect was not observed when migration during the first (constant-rate) drying period was substantially reduced, but the highest recovery angles were obtained when maximum migration to the fabric surfaces occurred. The probable explanation is that time is required for diffusion into the fibers by the methylol- melamine concentrated in the fabric surfaces. Estimates of surface resin, and of the rates of diffusion support this hypothesis.
Interaction of the Protein Kinase Raf-1 with 14-3-3 Proteins (1994)

Members of a family of highly conserved proteins, termed 14-3-3 proteins, were found by several experimental approaches to associate with Raf-1, a central component of a key signal transduction pathway. Optimal complex formation required the amino-terminal regulatory domain of Raf-1. The association of 14-3-3 proteins and Raf-1 was not substantially affected by the activation state of Raf.

Morphology and composition of spray-flame-made yttria-stabilized zirconia nanoparticles (2005)

Homogeneous yttria-stabilized zirconia (YSZ) with 8-31 nm average crystallite and particle diameter containing 3-10 mol% yttria are made by flame spray pyrolysis (FSP) of various yttrium and zirconium precursors at production rates up to 350 g h(-1). Product particles are characterized by N(2) adsorption (BET), transmission electron microscopy (TEM), energy-dispersive x-ray spectroscopy (EDS) and x-ray diffraction (XRD). The effect of liquid precursor composition on product particle morphology, composition and crystallinity is investigated. The yttria content does not affect the product primary particle and crystal sizes of homogeneous YSZ. These are determined, in turn, by the process enthalpy content and overall metal concentration. Flame-made YSZ nanoparticles of homogeneous composition and morphology are formed when using either only organometallic zirconium and yttrium precursors or 2-ethylhexanoic acid as solvent and inexpensive zirconium carbonate and yttrium nitrate hexahydrate as precursors. In contrast, and consistent with the literature, hollow or inhomogeneous YSZ particles are made when organometallic zirconium and yttrium nitrate precursors of high water content are employed, especially at high production rate. The ratio of XRD-determined small to large sizes for inhomogeneous crystalline particles is an effective quantitative measure of their degree of inhomogeneity. For such inhomogeneous particles nitrogen adsorption is not a reliable technique for the average grain size as it relies on integral properties of the particle size distribution.

Gallstones: Laparoscopic Treatment, Intracorporeal Lithotripsy Followed by Cholecystostomy or Cholecystectomy - A Personal Technique (1989)

The authors describe a personal technique for the treatment of gallbladder stones using a laparoscopic approach. They first evacuate the stones with the aid of an intracorporeal ultrasonic lithotriptor (L.U.S. Olympus). They next perform a cholecystostomy or a cholecystectomy. The first 40 cases are reported, and good results were obtained.
Performance evaluation of an agent server capable of hosting large numbers of agents (2001)

Recently Web sites have been providing users with services in accordance with their preference data. In addition to such configuration services, notification services, which process jobs in response to events which occurred at a server in the users' absence, and asynchronous services, which perform jobs after users submit requests, are also available. An agent server architecture which manages users' agents on the server side is proposed for developing systems which provide such services. Such agent servers must be able to sustain high performance. In this paper, we demonstrate that the agent server approach can achieve higher performance than an existing approach which uses DBMS. Also, we describe the performance characteristics of the agent server.
Hybrid battery charging system combining OBC with LDC for electric vehicles (2014)

It presents a hybrid battery charging system unifying an on-board charger (OBC) with a low voltage dc-to-dc converter (LDC) for small and light design of EV charger. The proposed hybrid charger consists of three H-bridge converters including a selective switch, a high frequency transformer, and inductors. Front-end converter connected to the grid by a selective switch has two roles. One is to obtain unity power factor by ac-to-dc converting. It belongs to one of the behavior of OBC. The other is to charge an auxiliary battery by working a step-down converter. Back-end converter employs a transformer to ensure galvanic isolation between the grid and EV. It charges propulsion battery by phase-shift control, and as the occasion demands, energy stored in propulsion battery discharges to dc-link capacitor to supply power to the grid or auxiliary battery. To verify the validity of the proposed approach, we carry out computer-aided simulations and experiments.
Myxovirus Antibody Increases in Human Connective Tissue Disease (1970)

Antibodies to measles and parainfluenza type 1 viruses were significantly increased in systemic lupus erythematosus and Reiter's syndrome. Of the individuals with highest titers of measles antibody, 75 percent had neurologic illness. Persistent virus infection may be a factor in the pathogenesis of these diseases.
Selective alkylation and allylation of allylic halides by tetraorganoindates: regio- and stereo-selective synthesis of rosefuran and sesquirosefuran (1995)

Tetraalkylindates regioselectively alkylate allylic bromides at the α-carbon. In this way, 1,5-dienes have been regio- and stereo-selectively synthesized by the allyl–allyl coupling of allylic bromides and allylic indates, including rosefuran 1 and sesquirosefuran 3.
Improvement in electron emission from carbon nanotube cathodes after Ar plasma treatment (2004)

Carbon nanotube (CNT) cathode surfaces have been exposed to Ar plasma and the emission characteristics were measured. When a CNT cathode was exposed to Ar plasma for 3 min, the emission characteristics were improved. The emission current increased after an Ar plasma treatment for 3 min by three orders of magnitude from 9.0×10−5 to 3.3×10−1 mA/cm2 at 4.0 V/μm with a decrease in turn-on voltage from 3.3 to 1.7 V/μm. According to scanning electron microscopy images, entangled CNT bundles were raveled out by Ar plasma treatment.
Bacteria of the Genus Rhodococcus Accompanying Green Algae in Nature and under Conditions of Laboratory Cultivation (2000)

The species composition of bacteria of the genus Rhodococcus isolated from the algal samples taken in nature, as well as from the cultures of halophilous, freshwater, and aerophilous green algae, was studied. It has been found that the isolated strains of the genus Rhodococcus belong to the species Rhodococcus erythropolis, R. luteus and R. maris. Some species of the genus Rhodococcus were found to be associated with the definite genera of algae, their habitats and conditions of cultivation. The data obtained suggest that bacteria of the genus Rhodococcus incorporated into natural algal and bacterial communities continue to act as accompanying organisms under conditions of prolonged laboratory cultivation and in storage in collections.
The Present state and Future of Macromolecules for Dental Applications (1977)

Abstract Dentistry has always been dependent on the advances of science and engineering for improvement of methods and procedures. The search for desirable preventive, corrective, and restorative dental materials, because of the exacting requirements that are demanded for this application, has necessarily been restricted to a limited class of materials. Dentistry led the health science field in taking advantage of the rapidly expanding family of polymeric materials that have been developed over the years in the United States and abroad. The volume of dental resins used is insignificant compared to the total consumption of plastics. Yet, the impact of scientists working on dental problems has done much to increase the usefulness of macromolecular materials. Examples of such research are epoxy resins, which were first synthesized by Pierre Castan in the laboratories of a Swiss dental manufacturer; amine-peroxide systems specially developed to obtain rapid-curing, chemically activated dental resins which are now widely used in the cure of polyester resins; and self- curing acrylic resins which have found diverse applications as cements in orthopedic and neurosuigical techniques.

Selective One-Step Extraction of <b><i>Arabidopsis thaliana</i></b> Seed Oleosins Using Organic Solvents (2007)

Oleosins are hydrophobic proteins from oleaginous seeds, surrounding and stabilizing oil bodies. They are known to display interesting interfacial properties. Specific sera were raised against four different A. thaliana oleosins and used in dot-blot assays for oleosin quantification. These assays were used to set up extraction of oleosins from A. thaliana seeds. One mixture of chloroform/methanol gave optimal oleosin extraction. Extracted proteins represented 9% of seed proteins and were identified by immunoblot and proteomic analyses. Oleosins accounted for 79% of the extracted proteins. This simple one-step procedure allows selective extraction and concentration of oleosins from seeds without tedious oil body purification. Oleosin extract was indeed used to demonstrate the presence of the rare oleosin S5 in mature seeds. Moreover, this method will be useful to investigate the potential use of oleosins as emulsifier and to question their possible allergenicity.
Comparison of in vitro dialysis release methods of loperamide-encapsulated liposomal gel for topical drug delivery (2014)

This study has demonstrated that the actual method used for equilibrium dialysis plays a significant role in determining the true characteristics of a topical nanoformulation, with Method 3 providing the most accurate indication of the release of a hydrophobic drug from a topical liposomal formulation.
Simulation Study of Regenerative Inverter for DC Traction Substation (2005)

The substation of DC system, which generates DC line voltage with 12-pulse diode rectifiers, has the rise in DC line voltage because it doesn't absorb the regenerative power caused by electric brakes of a train. To tackle this problem, the IGBT regenerative inverter is installed in the DC system to recycle the surplus regenerative power by delivering it to the supply grid. In this paper, the regenerative motion control algorithm of 3-phase PWM AC/DC converter is used to deliver the regenerative power to the supply grid and stabilize the line voltage. It is confirmed that the high quality regenerative power is delivered to the supply grid using computer simulations
Scaling of sensitivity and efficiency in planar microresonators for electron spin resonance (2008)

Electron spin resonance (ESR) of volume-limited samples or nanostructured materials can be made significantly more efficient by using microresonators whose size matches that of the structures under investigation. We describe a series of planar microresonators that show large improvements over conventional ESR resonators in terms of microwave conversion efficiency (microwave field strength for a given input power) and sensitivity (minimum number of detectable spins). We explore the dependence of these parameters on the size of the resonator and find that both scale almost linearly with the inverse of the resonator size. Scaling down the loops of the planar microresonators from 500 down to 20 mum improves the microwave efficiency and the sensitivity of these structures by more than an order of magnitude and reduces the microwave power requirements by more than two orders of magnitude.
Spectrum Aggregation Based Cooperative Communications in the LTE Further Evolution (2010)

The wide band radio transmission may be implemented in two parallel ways:to design a new system with larger bandwidth;to construct a cooperative system based on existing systems.The former is a spectrum aggregation scheme based on multi-carrier transmission within one system,while the latter fulfills spectrum aggregation based on multi-carrier transmission among systems.On one hand,the advantage of the multi-carrier transmission scheme within system and among systems lies in that the existing Radio Frequency (RF) techniques and elements can be sufficiently utilized,so the system cost can be decreased.On the other hand,the spectrum aggregation among systems,especially among heterogeneous air-interfaces,can not only expand the basic bandwidth functions,but also fulfill efficient spectrum usage for Frequency Division Duplex (FDD) system under the unbalanced Uplink/Downlink (UL/DL) service scenario and efficient guard band usage between FDD and Time Division Duplex (TDD) system.Commercially,this solution is more significant for operators.
Nuclear staining with alum hematoxylin (2009)

The hematoxylin and eosin stain is the most common method used in anatomic pathology, yet it is a method about which technologists ask numerous questions. Hematoxylin is a natural dye obtained from a tree originally found in Central America, and is easily converted into the dye hematein. This dye forms coordination compounds with mordant metals, such as aluminum, and the resulting lake attaches to cell nuclei. Regressive formulations contain a higher concentration of dye than progressive formulations and may also contain a lower concentration of mordant. The presence of an acid increases the life of the solution and in progressive solutions may also affect selectivity of staining. An appendix lists more than 60 hemalum formulations and the ratio of dye to mordant for each.
Gastroesophageal reflux disease and its consequences. (1992)

Gastroesophageal reflux is a common event characterized by orad movement into the esophagus of gastric and/or duodenal contents. Reflux may produce either no damage to the esophageal mucosa or erosions, exudates, ulcerations, strictures, and/or Barrett's (columnar-lined) esophagus. In addition to the esophagus, all the anatomic structures from the pharynx to the lung may be affected by reflux. Numerous factors promote abnormal esophageal mucosal contact time with acid and pepsin. These include incompetent lower esophageal sphincter, impaired esophageal clearance, increased frequency of reflux episodes, delayed gastric emptying, and the presence of a hiatal hernia. The relative contribution of each of these factors in the pathogenesis of esophageal mucosal disease has not been clearly defined. Epidemiologic and clinical data support an association between gastroesophageal reflux and pulmonary disease. Most asthmatic patients, independent of bronchodilator use, have evidence of gastroesophageal reflux, as demonstrated by ambulatory pH testing, endoscopy, and the presence of reflux symptoms. Studies with antireflux agents indicate that partial or complete symptom relief and healing of esophagitis are obtained in about half the patients using H2-receptor antagonists and almost all patients using omeprazole. Preliminary evidence suggests that surgical correction of reflux may lead to improved pulmonary status. Controlled clinical trials are needed, however, to further determine whether effective gastric acid suppression will improve reflux-associated pulmonary disease.
Melt spinning of metallocene catalyzed polypropylenes. I. On‐line measurements and their interpretation (2001)

Abstract The melt spinning of metallocene catalyzed isotactic polypropylene resins was investigated. The details are presented for on‐line studies performed on six miPP resins with melt flow rates (MFRs) between 10 and 100 and a Ziegler–Natta catalyzed isotactic polypropylene resin with a MFR of 35 for comparison. The on‐line studies indicated that, as the molecular weight and polydispersity increased, crystallization occurred closer to the spinneret at higher crystallization temperatures and under lower spin line stresses. Further, as the spinning speed increased, crystallization occurred closer to the spinneret at higher crystallization temperatures because of increased stress in the spin line. These observations were interpreted in terms of an increased rate of crystallization caused by increased molecular orientation in the spin line with increasing molecular weight and increasing spinning speed. This “stress‐enhanced” crystallization was further interpreted in terms of an increased rate of crystal nucleation. It was further concluded that the narrower molecular weight distribution of metallocene resins was the primary factor that produced differences in the structure and properties of fibers spun from these resins compared to those of Ziegler–Natta catalyzed resins of similar weight‐average molecular weight or MFR. © 2001 John Wiley & Sons, Inc.

Ethylene Biosynthesis and Accumulation under Drained and Submerged Conditions (A Comparative Study of Two Rumex Species) (1996)

A model is presented of the regulation of ethylene biosynthesis in relation to submergence and flooding resistance. It is based on time-course measurements of ethylene production, ethylene accumulation, and concentrations of free and conjugated 1-aminocyclo-propane-1-carboxylic acid (ACC) in submerged and drained flooding-resistant Rumex palustris Sm. and flooding-sensitive Rumex acetosella L. plants. From these data, in vivo reaction rates of the final steps in the ethylene biosynthetic pathway were calculated. According to our model, submergence stimulates ACC formation and inhibits conversion of ACC to ethylene in both Rumex species, and as a result, ACC accumulates. This may explain the stimulated ACC conjugation observed in submerged plants. Although submergence inhibited ethylene production, physical entrapment increased endogenous ethylene concentrations in both flooding-resistant R. palustris and flooding-sensitive R. acetosella plants. However, R. palustris plants controlled their internal ethylene levels in the long term by a negative regulation of ACC synthase induced by ethylene. In flooding-sensitive R. acetosella plants, absence of negative regulation increased internal ethylene levels to more than 20 [mu]L L-1 after 6 d of submergence. This may accelerate the process of senescence and contribute to their low level of flooding resistance.
A prescribing incentive scheme for non-fundholding general practices: an observational study (1996)

The prescribing behaviour of non-fundholding general practitioners responded to financial incentives in a similar way to that of fundholding practitioners. The incentive scheme did not seem to reduce the quality of prescribing.
A Wirelessly-Powered Homecage With Segmented Copper Foils and Closed-Loop Power Control (2016)

A new wireless electrophysiology data acquisition system, built around a standard homecage, is presented in this paper, which can power up and communicate with sensors and actuators/stimulators attached to or implanted in small freely behaving animal subjects, such as rodents. Key abilities of the energized homecage (EnerCage) system is enabling longitudinal experiments with minimal operator involvement or interruption, while providing test subjects with an enriched environment closer to their natural habitat, without the burden of being tethered or carrying bulky batteries. The magnetic resonant multi-coil design used in the new EnerCage-HC2 automatically localizes the transmitted electromagnetic power from a single transmitter (Tx) coil at the bottom of the cage toward the receiver coil (Rx), carried on/in the animal body, obviating the need for tracking the animal or switching the coils. In order to increase the resonators' quality factor (Q > 166) at the desired operating frequency of 13.56 MHz, while maintaining a high self-resonance frequency [Formula: see text], they are made of wide copper foils and optimally segmented based on a set of design rules that can be adopted for experimental arenas with different shapes and dimensions. The Rx rectified voltage is regulated at a user-defined window [Formula: see text] by a Tx-Rx closed-loop power control (CLPC) mechanism that creates a volume inside the homecage with 42 mW of power delivered to the load (PDL), and a homogeneous power transfer efficiency (PTE) plane of 14% on average at ∼7 cm height, plus stability against angular mis-alignments of up to 80°.
