Structure property relations in BiFeO3/BaTiO3 solid solutions (2000)

BiFeO 3 , when forming a solid solution with BaTiO3, shows structural transformations over the entire compositional range. Above 70 mole % of BiFeO3 the structure is rhombohedral and below 4 mole %, it is tetragonal. In between the structure is cubic. The ferroelectric TC decreases with increasing composition of BaTiO3 and a relatively small relaxation is observed. Impedance measurements showed a structural dependence and analysis of which has clearly shown that the capacitance observed is from the bulk of the sample. Relaxation time (τ) of BiFeO3 was estimated using the relaxation times of the intermediate compositions. Magnetization measurements showed field induced ferromagnetism. As the structure becomes cubic with increasing concentration of BaTiO3, paramagnetism sets in, as evidenced by the electron spin resonance spectra.

<i>Pseudomonas aeruginosa</i> inhibits endocytic recycling of CFTR in polarized human airway epithelial cells (2005)

The most common mutation in the CFTR gene in individuals with cystic fibrosis (CF), DeltaF508, leads to the absence of CFTR Cl(-) channels in the apical plasma membrane, which in turn results in impairment of mucociliary clearance, the first line of defense against inhaled bacteria. Pseudomonas aeruginosa is particularly successful at colonizing and chronically infecting the lungs and is responsible for the majority of morbidity and mortality in patients with CF. Rescue of DeltaF508-CFTR by reduced temperature or chemical means reveals that the protein is at least partially functional as a Cl(-) channel. Thus current research efforts have focused on identification of drugs that restore the presence of CFTR in the apical membrane to alleviate the symptoms of CF. Because little is known about the effects of P. aeruginosa on CFTR in the apical membrane, whether P. aeruginosa will affect the efficacy of new drugs designed to restore the plasma membrane expression of CFTR is unknown. Accordingly, the objective of the present study was to determine whether P. aeruginosa affects CFTR-mediated Cl(-) secretion in polarized human airway epithelial cells. We report herein that a cell-free filtrate of P. aeruginosa reduced CFTR-mediated transepithelial Cl(-) secretion by inhibiting the endocytic recycling of CFTR and thus the number of WT-CFTR and DeltaF508-CFTR Cl(-) channels in the apical membrane in polarized human airway epithelial cells. These data suggest that chronic infection with P. aeruginosa may interfere with therapeutic strategies aimed at increasing the apical membrane expression of DeltaF508-CFTR.
Automatically locating relevant programming help online (2012)

While maintaining software systems, developers often encounter compilation errors and runtime exceptions that they do not know how to solve. Solutions to these errors can often be found through discussions with other developers on the Internet. Unfortunately, many of these online discussions do not contain relevant answers. We have developed an approach to automatically query and analyze online discussions to locate relevant solutions to programming problems. Our tool, called Dora, is integrated into Visual Studio and allows developers to query and evaluate solutions within their development environment, enabling them to reduce context switching between their development tasks and their search sessions. We have performed a semi-controlled experiment to validate the utility of our search approach with 18 tasks, finding that our approach provides 55% more relevant results than traditional web searching approaches.
Fritzing (2009)

Today a growing community of DIY-practitioners, artists and designers are using microcontroller-based toolkits to express their concepts for digital artifacts by building them. However, as these prototypes are generally constructed using solder-free technologies, they are often fragile and unreliable. This means a huge burden of care and upkeep for these inventions when they are either exhibited or sold.
Independent Regulation of Lymphocytic Choriomeningitis Virus-Specific T Cell Memory Pools: Relative Stability of CD4 Memory Under Conditions of CD8 Memory T Cell Loss (2001)

Abstract Infection of mice with a series of heterologous viruses causes a reduction of memory CD8+ T cells specific to viruses from earlier infections, but the fate of the virus-specific memory CD4+ T cell pool following multiple virus infections has been unknown. We have previously reported that the virus-specific CD4+ Th precursor (Thp) frequency remains stable into long-term immunity following lymphocytic choriomeningitis virus (LCMV) infection. In this study, we questioned whether heterologous virus infections or injection with soluble protein CD4 Ags would impact this stable LCMV-specific CD4+ Thp memory pool. Limiting dilution analyses for IL-2-producing cells and intracellular cytokine staining for IFN-γ revealed that the LCMV-specific CD4+ Thp frequency remains relatively stable following multiple heterologous virus infections or protein Ag immunizations, even under conditions that dramatically reduce the LCMV-specific CD8+ CTL precursor frequency. These data indicate that the CD4+ and CD8+ memory T cell pools are regulated independently and that the loss in CD8+ T cell memory following heterologous virus infections is not a consequence of a parallel loss in the memory CD4+ T cell population.
Hydraulic Fracture Diagnostics (1996)

Summary Fracture diagnostics can provide important information on fracture geometry that can be used to improve stimulation effectiveness and reduce costs. Several cost-effective diagnostics already exist, and the technology for obtaining a full image of the fracture is progressing to the point of practical application. Introduction Hydraulic fracturing is an interesting technology that has evolved to a mature, complex level; is critical to the economical production of hydrocarbons; and is a significant portion of the well-development cost. Nevertheless, it is still not understood fully or, at least, is interpreted poorly. Some may argue that the physical laws governing fracturing are known and fracture models are accurate, but the emergence of "new mechanisms" every few years (e.g., scale-dependent fracture toughness, complex fracturing, dilatancy, and convection) suggests that the basic physics incorporated into models has not been as comprehensive as required to model a fracture fully. The reasons for the uncertainty surrounding the fracturing process are quite clear. The Earth is a complex, discontinuous medium, and historically there has been limited technology for observing or inferring fracturing results. Nothing can be done about the complexity of typical reservoirs in the Earth, and one can expect that difficulties with complexity will increase as more marginal reservoirs are exploited. On the other hand, diagnostic capabilities continue to improve and technology is reaching the point where fracture diagnostics can be applied by the average producer in problem situations, in new fields, or for validation of new fracturing techniques. Furthermore, as operators continue to work in difficult, complex lithologies, it becomes clear that stimulation problems cannot be solved without some diagnostic data from which judicious decisions can be made. Diagnostics cost money, but trial-and-error approaches often cost more money and can result in lost wells. Decisions on well spacing, field layout, sand concentrations and volumes, number of zones that can be stimulated in one treatment, optimum perforation schedule, and many other operational parameters can be made correctly if the proper diagnostic information is available in a timely manner. This article briefly reviews the status of stimulation diagnostics and provides some information on newer technology that is becoming available. Some of these techniques could provide information that will improve production or reduce costs.
Gift cards: a review and research agenda (2015)

Gift cards have received limited study despite being a key element of many retailers’ strategies. One reason may be that approaching the study of gift cards from a traditional economic perspective, i.e. ignoring social relationships, leaves little justification for the rapid increase in gift card sales. Failing to see the value of gift cards, many commentators go so far as to argue against the purchase of gift cards, suggesting that consumers would better off using other gift types. This misses the important point that givers voluntarily buy cards and receivers enjoy gaining them. Consumers undoubtedly perceive the value in gift cards. We suggest that taking a broader perspective on consumer behavior and considering consumers involved in social systems that encourage gift giving, allows us to see the value gift cards create while allowing us to address the concerns gift cards raise more effectively. In this article, we detail the benefits created for givers, receivers, and merchants by the use of gift cards. We highlight areas with significant public policy implications. We outline an agenda for some promising areas of research, including seeking to gain a better understanding of the psychology of giving gift cards and the economics of retail strategies dependent upon gift card usage.
CHEMISTRY OF HOP CONSTITUENTS XI*. SOME OBSERVATIONS ON THE ISOMERIZATION OF HUMULONE (1957)

It is suggested that the bitter bacteriostatic principles in beer which are derived from humulone, cohumulone and adhumulone should be termed isohumulone A, isocohumulone A and isoadhumulone A respectively. These materials have been isolated from beer and some of their characteristics are described. The product obtained when humulone is boiled in alcoholic alkaline solution is shown to be a complex mixture. Relatively pure isohumulone A can, however, be obtained by treating humulone either with hot aqueous alkali or with cold potassium tertiary butoxide in tertiary butanol. The racemization of humulone by heat and its behaviour towards acid have been investigated.
Selective Laser Melting (2012)

Abstract Manufacturing enterprises in highwage countries such as Germany are increasingly being exposed to global competition. These enterprises are confronted by an increasing demand for individualized, high quality as well as low‐cost products [1]. Additive manufacturing methods have accelerated their technological capability in the last few years and provide great potential to fulfill these challenges. The most common additive manufacturing method is called Selective Laser Melting (SLM), developed at the Fraunhofer Institute for Laser Technology ILT [2].
The case for efficient file access pattern modeling (2003)

Most modern I/O systems treat each file access independently. However events in a computer system are driven by programs. Thus, accesses to files occur in consistent patterns and are by no means independent. The result is that modern I/O systems ignore useful information. Using traces of file system activity we show that file accesses are strongly correlated with preceding accesses. In fact, a simple last-successor model (one that predicts each file access will be followed by the same file that followed the last time it was accessed) successfully predicted the next file 72% of the time. We examine the ability of two previously proposed models for file access prediction in comparison to this baseline model and see a stark contrast in accuracy and high overheads in state space. We then enhance one of these models to address the issues of model space requirements. This new model is able to improve an additional 10% on the accuracy of the last-successor model, while working within a state space that is within a constant factor (relative to the number of files) of the last successor model. While this work was motivated by the use of file relationships for l/O prefetching, information regarding the likelihood of file access patterns has several other uses such as disk layout and file clustering for disconnected operation.
The Application of Anti-trust Legislation to Labor Unions--Past, Present, and Proposed (1950)

Today labor unions enjoy practically complete immunity from the federal antitrust statutes, which now prevent only businessmen from imposing unreasonable restraints on trade.This immunity of labor is unique in the long history of antitrust law.Certain labor activities were held to violate the common law on restraints of trade before the passage of the first federal antitrust law, the Sherman Act,' and then, until 1941, the statutory law was held to curb the unions. 2 This labor immunity has left the nation so exposed to exploitation by union-imposed restraints of trade that the wisdom of modifying the present policy is now receiving serious consideration.The critics of the unions' immunity cite John L. Lewis' prolonged fight with the mine owners as an example of the ability of a powerful union to control production in essential commodities. 3Without examining the merits of the unions' or the operators' contention, it is apparent that the tactics adopted by the unionwork stoppages separated by periods of production on a three day weekhave resulted in a grievious loss to the national economy.It is also apparent that this control of production would be a violation of the Sherman Act if imposed by any party other than the union. 4 None of our present laws prevent the unions from adopting competition-stifling tactics.While the Taft-Hartley Act provides for an eighty-day injunction in the event of a national emergency, 5 there

No-history method of intraocular lens power calculation for cataract surgery after myopic laser in situ keratomileusis (2006)

The no-history method is a viable alternative for IOL power calculation after myopic LASIK when the refractive surgery data are not available.
Design and evaluation of a new capillary electrochromatography system (1999)

A new computer-controlled capillary electrochromatography (CEC) system was built. Up to +/- 60 kV can be used for CEC separation, and buffer vials can be pressurized to prevent bubble formation and to facilitate conditioning and rinsing of columns. This CEC system is compact and flexible. Short columns can be used to achieve fast separations. A fiber optic detection assembly is used to separate the main body of the UV detector from the high potential to prevent potential discharge and disturbance of the UV absorbance signal. This system was evaluated by separating 16 polycyclic aromatic hydrocarbons (PAHs) on different types of octadecyl silane (ODS) particles. Over 200,000 plates/m (k = 4.4) were obtained using 1.5 microm ODS particles. Voltage programming was used to reduce the analysis time by nearly 50%.
On the use of dual frequency nematic material for adaptive optics systems: first results of a closed -loop experiment (2000)

The use of liquid crystal devices for wavefront control has been suggested and implemented by several authors. In this paper we report some preliminary results on the use of Nematic based liquid crystal devices. Several experimental efforts have been carried out in the past few months. One of the main aims was to characterize a new device that uses dual frequency nematic material in a closed loop arrangement.
Building, visualizing, and computing on surfaces of evolution (1988)

An approach is presented to giving a robot the ability to move safely through a scene using its own vision that depends, as in humans, on the ability to operate explicitly in both space and time and to exploit the massive redundancy present in the hundreds of views that can be obtained when moving through a scene. The mechanism for integrating these space-time factors is a 3-D surface-building process called the Weaving Wall. In robotic navigation work the 3-D surfaces built by its process represent the space-time evolution of scene images, and this representation, in conjunction with geometric constraints, enables the 3-D structure of the scene to be determined. In other domains where there is a gradual evolution of data over a third dimension (e.g. medical tomography), the surfaces constructed by the Weaving Wall are immediately of value for their topographic structure. The designs of both the surface-building and scene-reconstruction processes make them well suited for real-time operation, given appropriate hardware.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
DC-Link Voltage Stabilization for Reduced DC-Link Capacitor Inverter (2013)

In conventional motor drive systems using pulsewidth modulation (PWM) inverters, large electrolytic capacitors are used for stabilization of the dc-link voltage. Since the electrolytic capacitors are bulky and reduce reliability of the system due to short lifetime, there have been many efforts to eliminate or reduce the electrolytic capacitors in the motor drive system. However, the PWM inverter with reduced dc-link capacitor has a problem that the dc-link voltage is less stable compared to the conventional inverter because the capability of storing energy is also reduced. In this paper, a dc-link voltage stabilization algorithm using an active damping is proposed so that the dc-link voltage can be stabilized with reduced dc-link capacitor. To achieve load-/source-independent stabilization, a source state estimator which estimates both source voltage and current is also proposed. The fluctuation of the dc-link voltage due to a step load change can be also suppressed under the tolerance range using the estimated source current. The effectiveness of the proposed methods is evaluated by experimental results.
Geriforte stimulates antioxidant defense system. (1998)

Geriforte, a herbomineral preparation, feeding at 1 g% dose level for 4 weeks significantly increased catalase (CAT), superoxide dismutase (SOD) and glutathione peroxidase (GPx) activities in liver of mice. In rats, in addition to these enzymes, the levels of reduced glutathione (GSH) were also significantly enhanced. However, only SOD in mice and, CAT and SOD activities in rat lung were significantly elevated after Geriforte treatment. A decrease in superoxide (O2-) and H2O2 release by alveolar macrophages obtained from rats fed on Geriforte containing diet was observed. The results suggest that Geriforte feeding stimulates antioxidant defense system and indicate the future preventive/therapeutic prospects of this preparation against free radical damage under various pathological states.
Specular- and Diffuse-reflection-based Face Spoofing Detection for Mobile Devices (2019)

In light of the rising demand for biometric-authentication systems, preventing face spoofing attacks is a critical issue for the safe deployment of face recognition systems. Here, we propose an efficient face presentation attack detection (PAD) algorithm that requires minimal hardware and only a small database, making it suitable for resource-constrained devices such as mobile phones. Utilizing one monocular visible light camera, the proposed algorithm takes two facial photos, one taken with a flash, the other without a flash. The proposed $SpecDiff$ descriptor is constructed by leveraging two types of reflection: (i) specular reflections from the iris region that have a specific intensity distribution depending on liveness, and (ii) diffuse reflections from the entire face region that represents the 3D structure of a subject's face. Classifiers trained with $SpecDiff$ descriptor outperforms other flash-based PAD algorithms on both an in-house database and on publicly available NUAA, Replay-Attack, and SiW databases. Moreover, the proposed algorithm achieves statistically significantly better accuracy to that of an end-to-end, deep neural network classifier, while being approximately six-times faster execution speed. The code is publicly available at https://github.com/Akinori-F-Ebihara/SpecDiff-spoofing-detector.
A preliminary report on the antiestrogenic activity of the petals of Butea frondosa flowers. (1966)

Varying dosages of Butea frondosa flower extract concentrate were used to study the antiestrogenic activity in mice. A slight modification of the 3-day immature mice bioassay of Edgren and Calhoun was used. Sc injection of estrone and doses of 27 6.1 and 3.2 mg/kg body weight/day of extract resulted in a uterine weight increase less than that observed when estrone was administered separately (p less than .01 at each dose). 1.6 mg/kg body weight of extract administered with estrone caused only insignificant differences. It appears that the extract of Butea frondosa has antiestrogenic capabilities at a minimum dosage of 3.2 mg/kg body weight.
MECHANISMS OF TOLERANCE INDUCED BY PG490-88 IN A BONE MARROW TRANSPLANTATION MODEL (2002)

Host-specific tolerance induced by PG490-88 in a murine bone marrow transplantation model is not due to deletion of alloreactive cells. Moreover, suppressor cells are not involved in the maintenance of tolerance. Rather, PG490-88 seems to lead to allogeneic tolerance either through the induction of a state of antigen-specific anergy of the responding T cells or through the induction of T-helper cell, type II (TH2) responses.
