Effect of Annealing on Performance of Solar Cells with New Oxide Absorber Mn2V2O7 (2017)

All-oxide solar cells are attractive due to their stability, low cost and ease of fabrication. Very few oxide-absorbers are known and the efficiencies are limited by low mobility and lifetimes. In this work, for the first time, photovoltaic properties of a new oxide semiconductor, Mn <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> V <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> O <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">7</sub> (MVO) are described. Optical measurements show that MVO has an indirect bandgap of 1.6 eV and a direct bandgap of 1.75 eV, which suggests that it absorbs efficiently in the visible region of the solar spectrum. The valence and conduction band positions of the intrinsically n-doped MVO film are determined to be at 5.5 eV and 3.9 eV. Schottky solar cells fabricated using Pt/MVO heterojunction show low short circuit current (J <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">SC</sub> ) and open circuit voltage (VOC).

Effects of pH‐variations on the kinetics of growth and energy metabolism in cultured T‐lymphoma cells: A microcalorimetric study (1992)

The progression of T-lymphoma cells (CCRF-CEM) growing in suspension has been monitored during long term (12-28 h) batch experiments using microcalorimetry. In parallel with the calorimetric measurements, changes in cell concentration, pH, p(O2) and concentrations of the main energy sources (glucose and glutamine) were determined. The overall metabolic rate per cell (as reflected by the heat production rate per cell, Pcell) and the growth rate decreased with time. These changes could be attributed solely to the decrease in pH of the medium until the total heat production, Q, exceeded 1.2 J per ml (corresponding to an incubation time of 20 h of a batch having an initial cell concentration of 1 x 10(6) cells per ml). The lowering of p(O2) to a level of 0.02 mmol/l or the decrease in concentrations of glucose and glutamine to 7.7 and 1.3 mmol/l, respectively, did not influence Pcell or the growth pattern. No "crowding effect" was observed for the cells in the investigated concentration range (0.6-1.3) x 10(6) cells per ml.
Selective mode excitation of piezoelectric disk-type resonator by electrode pattern definition (2010)

Contour-mode piezoelectric MEMS resonators have been widely studied as one of potential components for future multi-band RF solution based on cognitive radio technology, because its resonant frequency is generally determined by the size and shape. To apply them to applications at frequency of higher than hundreds MHz, a specific higher mode should be strongly excited. However, it is often difficult, because the higher order vibration is a compound mode including radial and rotational displacements. In this study, the displacement distributions of higher order wine-glass modes of disk-type resonators were derived from FEM modal analysis. Then, mechanically-coupled disk-array filters with baseball-type and doughnut-type electrodes were fabricated and tested. Using the doughnut-type electrodes, (2. 6) mode was selectively excited, and a filter characteristic at a center frequency of 500.3 MHz was obtained. It was numerically and experimentally confirmed that a well-designed electrode pattern enhanced a specific vibration mode and suppressed other modes by comparing different electrode patterns.
Oral Controlled‐Release Polymeric Drug Delivery Systems (2013)

This chapter focuses on the drug release mechanisms of oral dosage forms and polymers for controlled-release formulation. It deals with manufacturing technologies, and industrial applications of controlled-release drug products. In the case of oral controlled-release formulations, drug release occurs in a matter of hours, and pseudo-steady-state mechanistic models as well as empirical and semiempirical models are useful for this timescale to understand the underlying release mechanism. Determination of the release mechanism is a prerequisite for tailoring a release profile to target in vivo blood levels or for troubleshooting release rate variations from batch to batch. The chapter focuses on monolithic matrices, coated reservoir systems, and osmotic delivery products. It also provides key aspects related to the in vitro characterization of such systems.

Photoisomerization of tetraethyl 6,8,15,17-tetrahydro-7H,16H-5,18[1',2']-benzeno-9,14-ethenodibenzo[a,h]cyclotetradecene-7,7,16,16-tetracarboxylate. Structure of tetraethyl 2,3,3a,7b,9,10,10a,14b-hexahydro-1H,8H-3a,7b[1',2']-benzeno-10a,14b-ethenodibenzo[a,e]dicyclopenta[c,g]cyclooctene-2,2,9,9-tetracarboxylate as its methylene chloride solvate (1994)

The initially formed cyclophane product, tetraethyl 6,8,15,17-tetrahydro-7H,16H-5,18[1',2']-benzeno-9,14-ethenodibenzo[a,h]cyclotetradecene-7,7,16,16-tetracarboxylate (I), produced from the cyclization of 9,10-bis{[2,2-di(ethoxycarbonyl)]ethyl}anthracene by treatment with sodium hydride followed by 1,4-bis(bromomethyl)naphthalene, was completely isomerized into its intramolecular [4πs+4πs] cycloaddition product, tetraethyl 2,3,3a,7b,9,10,10a,14b-hexahydro-1H,8H-3a,7b[1',2']-benzeno-10a,14b-ethenodibenzo[a,e]dicyclopenta[c,g]cyclooctene-2,2,9,9-tetracarboxylate (II), when passed through a silica gel column under fluorescent light

Recursive principal components analysis using eigenvector matrix perturbation (2005)

Principal components analysis is an important and well-studied topic in statistics and signal processing. Most algorithms could be grouped into one of the following three approaches: adaptation based on Hebbian updates and deflation, optimization of a second order statistical criterion, and fixed point update rules with deflation. In this paper, we propose a completely different approach that updates the eigenvector and eigenvalue matrices with every new data sample, such that the estimates approximately track their true values. The performance is compared with traditional methods like Sanger and APEX algorithm, as well as with a similar matrix perturbation based method. The results show the efficiency of the algorithm in terms of convergence speed and accuracy
Method of deposition by molecular beam epitaxy (2023)

A method is described for reproducibly controlling layer thickness and varying layer composition in an MBE deposition process. In particular, the present invention includes epitaxially depositing a plurality of layers of material on a substrate with a plurality of growth cycles whereby the average of the instantaneous growth rates for each growth cycle and from one growth cycle to the next remains substantially constant as a function of time.
High-Capacity Tube Network Design Using the Hough Transform (2009)

A new airspace design concept, tube networks, could enable high-density operations with less air traffic control workload. To construct tubes optimally, it is necessary to identify the commonality of flight trajectories. This paper proposes a new strategy to cluster great circle flight trajectories for forming tubes. The Hough transform is applied to identify groups or clusters of great circle trajectories that could form the tube networks. The genetic algorithm is then applied to optimize the tube network. Results show that small deviations from great circle routes could yield tubes that accommodate significant traffic levels within feasible computational time.
Efficient Synthesis of ω-(<i>p</i>-Vinylbenzyl)polystyrene by Direct Functionalization of Poly(styryl)lithium with <i>p</i>-Vinylbenzyl Chloride in Hydrocarbon Solvent with Lithium 2,3-Dimethyl-3-pentoxide (2006)

The direct functionalization of poly(styryl)lithium (Mn ≈ 2000 g/mol) with p-vinylbenzyl chloride (VBC) has been investigated in hydrocarbon solvent. With a 9-fold excess of VBC and normal addition, the predominant product (55% yield) was the corresponding head-to-head dimer; the macromonomer was formed in only 20% yield as determined by 1H NMR analysis. MALDI-TOF MS analysis of the products showed that the other major side reaction products resulted from addition of PSLi to the vinyl group of VBC. However, in the presence of excess lithium halides (LiCl, LiBr) the amount of dimer formation was reduced (30%), but the yield of macromonomer was increased only slightly (27%). The principal impurity was the corresponding nonfunctional polystyrene attributed to hydrogen abstraction from VBC by PSLi. A high yield (≥98%) of ω-(p-vinylbenzyl)polystyrene macromonomer was obtained when the functionalization was effected in the presence of 10 equiv of lithium 2,3-dimethyl-3-pentoxide. No dimer formation was observed by SEC analysis, but the presence of a small amount (≤2%) of nonfunctional polystyrene was detected by MALDI-TOF MS analysis of the product.

The Effect of Microseparation on Corrosion Rates of Metal-on-Metal Total Hip Replacements (2015)

Abstract The poor performance of Metal-on-Metal (MoM) bearings has to date been blamed on “adverse loading” conditions. Studies have focused on the effect of cup inclination and microseparation on gravimetric wear rates and highlighted the importance of surgical technique when implanting such devices. Up to four fold increase in the wear rates of MoM bearings subjected to microseparation has been reported during the bedding-in period. The contribution of corrosive processes to overall material degradation during adverse loading has not previously been investigated. In the present study 28 mm HC CoCrMo alloy Total Hip Replacements were tested to 1 Mcycles under standard gait and severe microseparation conditions in an electrochemically instrumented hip simulator. An order of magnitude increase in material lost as a result of oxidation was noted (0.234 to 2.044 mm3/Mcycle) during microseparation. Corrosive degradation may therefore be a much more significant contribution to poor bearing performance under adverse loading than previously considered.
Dislocation Revelation for 4H-SiC by Using Vaporized NaOH: A Possible Way to Distinguish Edge, Screw and Mixed Threading Dislocations by Etch Pit Method (2014)

In this paper, we report a newly developed dislocation-revealing etch pit method for 4H-SiC single crystal, which can distinguish edge (TED, Burgers vector b = a ), elementary screw (TSD, b =1 c ) and mixed (TMD, b = c + a ) threading dislocations. In this method, vaporized NaOH gas was used to etch the Si-face of a SiC wafer at substrate temperature around 950 °C. By a side-by-side comparison between the optical images of the etch pits and the X-ray topographic (XRT) images, it has been found that threading dislocations (TDs) in SiC could be revealed as hexagonal etch pits with distinct geometrical features (shape, size and facet orientation) depending on their Burgers vectors. Based on these results, we consider this etch pit method as an easily-operated and inexpensive technique to categorize TDs, and it may help to promote our understanding on the different roles that these types of TDs have played in the performance degradation of SiC power devices.
Revision Augmentation Mastopexy: Indications, Operations, and Outcomes (2003)

In the absence of any published information on the indications, frequency, and outcomes of revision augmentation/mastopexy, an 8-year retrospective review was undertaken of all patients undergoing revision of a previous augmentation/mastopexy in the senior author's practice. The data collected included original implant type, location and mastopexy type, indication for revision, interval from original surgery, new implant type, location, and associated corrective surgical procedures. A simultaneous review was also performed of all primary augmentation/mastopexies done during the same period. Twenty patients underwent revision of 34 previously performed augmentation/mastopexies. Five patients underwent revisions of a prior revision. Fourteen were bilateral, while 6 were unilateral, for a total of 34 breasts. Forty patients underwent primary augmentation/mastopexy during the same period. Among the revisions, 10 implants were originally subglandular, while 24 were either partly or totally submuscular. Twelve of the previous mastopexies were periareolar, 2 were vertical, and 20 were of the inverted T-type. The indications for revision included capsular contracture in 11 of 20 (55%) patients, nipple ptosis in 11 of 20 (55%) patients, implant malposition in 7 of 20 (35%) patients, dissatisfaction with implant size in 6 of 20 (30%) patients, poor scar in 5 of 20 (25%) patients, breast ptosis in 4 of 20 (20%) patients, nipple malposition in 2 of 20 (10%) patients, and patient preference in 1 of 20 (5%) patients. Most patients had 2 or more indications for revision. The average duration to revision was 7 years. In 13 of 20 (65%) patients, no change in implant type was made. The remainder had exchanges to a different type. In 12 of 20 (60%) patients, no change in implant location was made, whereas 8 of 20 (40%) patients had a change to the subpectoral or dual plane position. In 18 of 20 (90%) patients, the revision included the same type of mastopexy, while in 2 of 20 (10%) patients, the type of mastopexy was changed. Corrective surgical procedures performed included repeat mastopexy, capsulectomy, change of implant type, change of implant location, change of implant size, capsulotomy, capsulorrhaphy, and scar revision. To date, all of the patients are satisfied with their appearance. Follow-up ranged from 2 months to 4 years. Revision augmentation mastopexy is not an uncommon procedure, occurring half as often as primary augmentation/mastopexy in our series. There were 8 common indications for revision, with capsular contracture and recurrent ptosis being the most common. Eight surgical procedures, in various combinations, were performed during revision, with repeat mastopexy being the most common.

Cardioprotection by Conditioning Mimetic Drugs (2016)

Drugs capable of mimicking IP exhibit a high therapeutic potential because of their properties of eliciting an effective cardioprotective signaling. Future studies should clarify the optimal doses and timing of administration of IP mimetic agents in order to favor the advent of new cardioprotective strategies beyond available reperfusive therapies.
A network switch for supporting high‐performance parallel processing by computers distributed in local areas (2001)

Abstract The authors have developed a communications architecture called RHiNET that is capable of high‐performance parallel processing by interconnecting PCs and WSs. RHiNET uses not only computers concentrated in one place but also computers used for daily business within buildings and within floors for parallel processing. Networks used by RHiNET should have high effective bandwidths and small latencies for high‐efficiency computing, as well as link lengths for connecting the computers within buildings and floors and a free topology. The former requirements are not satisfied sufficiently by the conventional LANs, while the latter is not satisfied by SANs which are used in cluster systems. RHiNET satisfies both conditions by using a switch having a large memory capacity. In this paper, the architecture and implementation of the RHiNET/SW1 switch used by RHiNET networks are discussed. A scheme called virtual cache is used in RHiNET/SW1 such that a large‐capacity packet buffer is installed by SRAM outside the switch ASIC. In addition, the performance of the switch is evaluated by a simulator. © 2001 Scripta Technica, Syst Comp Jpn, 32(14): 24–33, 2001
The genome sequence of the entomopathogenic bacterium Photorhabdus luminescens (2003)

Photorhabdus luminescens is a symbiont of nematodes and a broad-spectrum insect pathogen. The complete genome sequence of strain TT01 is 5,688,987 base pairs (bp) long and contains 4,839 predicted protein-coding genes. Strikingly, it encodes a large number of adhesins, toxins, hemolysins, proteases and lipases, and contains a wide array of antibiotic synthesizing genes. These proteins are likely to play a role in the elimination of competitors, host colonization, invasion and bioconversion of the insect cadaver, making P. luminescens a promising model for the study of symbiosis and host-pathogen interactions. Comparison with the genomes of related bacteria reveals the acquisition of virulence factors by extensive horizontal transfer and provides clues about the evolution of an insect pathogen. Moreover, newly identified insecticidal proteins may be effective alternatives for the control of insect pests.
Cartridge Bearing System for Space Applications (1999)

Conventional spin axis ball bearings have been unreliable in spacecraft, often failing by two heretofore uncontrolled processes: ball retainer instability and lubricant breakdown. The Space Cartridge Bearing System (SCBS) addresses each of these mechanisms directly, leading to a bearing system with absolute freedom from retainer instability and negligible lubricant degradation rate. The result is a reliable plug-in bearing cartridge with a definite design life.
A thermal dissipation characteristics of integrated in-wheel motor using SiC power module (2017)

In-wheel motor is one of the expected electric vehicle technologies which has superiority in the vehicle control aspects. However, the integrated in-wheel motor in which the inverter is integrated with the motor makes thermal problems because of the reduction of cooling area. This paper analyses a cooling system of the inverter integrated in-wheel motor and considers the operating conditions of the integrated SiC power module. This paper also shows the effectiveness of the cooling system using the motor case as the heat sink of the inverter and it can keep the temperature under maximum junction temperature of SiC power devices.
Evaluating Moving Target Defenses against Realistic Attack Scenarios (2023)

Defenders are continuously seeking new tools for better security, including proactive defenses like Moving Target Defense (MTD). MTD continuously changes the attack surface, but there's little research on combining different MTD techniques, and often attack scenarios considered are simple and unrealistic. This paper proposes to evaluate the combined effects of MTD techniques against practical and realistic attack scenarios through a simulation framework. Our results indicate that adopting MTD techniques in general improves the security of systems, but combinations can have varying levels of defense depending on the attack scenarios. Hence, our proposed approach provides a more realistic evaluation of MTD techniques and their combinations taking into account practical attack scenarios, which can aid decision-makers to make better-informed decisions.
Revisión sistemática de las tasas de supervivencia de implantes colocados en el seno maxilar injertado (2004)

Basandose en una revision sistematica de la bibliografia de 1986 a 2002, este estudio se propuso determinar la tasa de supervivencia de implantes dentales con forma de raiz colocados en el seno maxilar injertado. Otros objetivos secundarios eran determinar los efectos del material del injerto, las caracteristicas de la superficie del implante y la colocacion simultanea frente a la demorada en la tasa de supervivencia. Se realizo una busqueda en bases de datos elctronicas principales junto a una busqueda manual de las revistas mas relevantes. Se recogieron todos los articulos importantes siguiendo los criterios de inclusion especificos. Se revisaron articulos seleccionados para la extraccion de datos. La busqueda permitio reunir 252 articulos aplicables a los injertos de seno asociados al tratamiento con implantes. De estos, 39 cumplian los criterios de inclusion para los analisis de datos cualitativos. Solo tres de esos articulos eran ensayos controlados aleatorizados. La supervivencia global del implante en los 39 estudios incluidos era del 91,49%. La base de datos incluia 6.913 implantes colocados en 2.046 sujetos con un tiempo de seguimiento, estando ya los implantes sometidos a carga, de 12 a 75 meses. La supervivencia del implante era del 87,70% con injertos de hueso autogeno al 100%, del 94,88% cuando se combinaba hueso autogeno con varios sustitutos oseos y del 95,98% con injertos oseos formados solo por sustitutos oseos. La tasa de supervivencia para los implantes que tenian superficies rugosas y lisas era del 85,64 y del 95,98%, respectivamente. Los procedimientos inmediatos y demorados presentaban tasas de supervivencia similares del 92,17 y el 92,93%, respectivamente. Cuando los implantes se colocaban en senos maxilares injertados, el comportamiento de los implantes rugosos era mejor que el de los implantes lisos. Los materiales utilizados como sustitutos de hueso son tan eficaces como el hueso autogeno cuando se utiliza solo o en combinacion con hueso autogeno. Son necesarios estudios que utilicen un diseno en boca partida con una varible para validar estos hallazgos.
