Low AC loss structures in YBCO coated conductors with filamentary current sharing (2005)

Architectural design improvements, such as filamentation, to YBa/sub 2/Cu/sub 3/O/sub 7-x/ (YBCO) coated conductors can result in a more ac-tolerant version of the conductor. However, finely made striations in the conductor make filament breakage more probable. In this case, weakly linking the filaments can enable current sharing among the filaments of striated coated conductors while maintaining reduced hysteretic losses. Data is presented for a YBCO sample divided into superconducting filaments separated such that the transverse critical current density of the striation is significantly less than the longitudinal critical current density along the filaments. A LAO substrate was physically scribed with parallel incisions to adversely affect the subsequent epitaxial growth of the YBCO layer between the striations. Vibrating sample magnetometry measurements verified a reduction in hysteretic loss compared to a control sample of epitaxially grown YBCO on an unscribed LAO substrate. Since filamentation requires a twist in the conductor for practical applications, a discussion is also given outlining an alternate means of accomplishing this by placing a twist in the coated conductor architecture itself.

Fast sub-pixel motion estimation having lower complexity (2003)

This paper presents fast sub-pixel motion estimation having less computational complexity. The proposed methods are based on mathematical models of the motion compensated errors for moving picture compression. The methods need no interpolation from the integer-pixel search results. In order to decide the coefficients of the models, the motion compensated errors of the neighboring pixels around motion vectors are used. The errors were already obtained during the pixel accuracy full search. The models estimate the motion compensated errors at sub-pixel accuracy level. The proposed mathematical models are referred to as Model 1, Model 2, Model 3, modified Model 2, and modified Model 3, respectively. The simulation results show that the performance depends on the accuracy of the models. The performance of the proposed methods, having less computational complexity, is close to that of the full search method.
Job Search Methods: Internet versus Traditional (2000)

In the current “e-commerce” boom, much attention has been paid to how the Internet is transforming product markets. At the same time, the Internet also is transforming labor markets, altering the way workers look for jobs, and the way firms recruit workers. More than 2,000 Internet job search sites now exist, yet little is known of their effects on labor markets. What percentages of unemployed (and employed) Americans use the Internet to search for jobs? This article examines the frequency and incidence of Internet job search among U.S. workers, by race, gender, and other demographic characteristics, the location of the job search (from home, from work, or from other access points), and the relation between Internet search and traditional job search methods. Internet job search data are from a special supplement to the December 1998 Current Population Survey (CPS), which asked respondents about computer and Internet use. The traditional job search methods are from the monthly CPS, where they are used by the BLS to determine if a respondent is an active jobseeker. The nine traditional methods are: • Contacted employer directly • Contacted public employment agency • Contacted private employment agency • Contacted friends or relatives • Contacted school employment center • Sent resumes/filled applications • Checked union/professional registers • Placed or answered ads • Used other active search methods Note that there is a possibility of overlap between search for a job via the Internet and the traditional methods outlined in the CPS. For example, unemployed jobseekers who say they “contacted employers directly” may have done so through the Internet, perhaps submitting a resume via e-mail (Internet search) or they may have actually mailed or personally delivered a copy of the resume to potential employers (traditional search).
Why Children Talk to Themselves (2001)

If you could become the shadow of a 2- to 8-year-old, furtively tagging along as the child goes about his or her daily activities, you would notice a curious form of language behavior—remarks in which the child seems to talk to himself or herself or to no one in particular. This speech-to-self occurs frequently. It can surface in virtually any of the child’s pursuits—during fantasy play, drawing and painting, building with blocks, tackling academic tasks, idly passing the time of day, and quieting down before naptime or nightly sleep. Researchers call this spontaneous, self-directed talk private speech. Unlike adults, who self-consciously talk to themselves only in solitary moments, young children freely use private speech in public. So at ease are preschool and primary-school children in speaking to themselves in front of others that on observing this behavior, many adults question its normalcy! “Confused,” “touched,” and “strange” are among the descriptors I have heard them apply to self-talking children, generalizing from “crazy people,” who not only speak aloud to fantasized audiences but also act improperly in a great many ways because they are indifferent to their social surroundings. To be sure, talking to oneself in the midst of a roomful of people is not acceptable in the adult social world. Yet all of us engage in private speech from time to time. And it is ubiquitous in early childhood. When children between the ages of 3 and 10 are observed in classrooms, private speech makes up as much as 20 percent to 60 percent of their language. Why do young children engage in it so frequently? To grasp the significance of private speech in the life of the child, let’s begin by looking at it in ourselves. When are you most likely to talk out loud to yourself? In response to this question, most adults say they engage in audible self-talk when they face cognitive, emotional, or social challenges. Here are some self-reports: • “At the end of a busy day, when I’m tired and distracted, I sometimes find myself looking for an important document, for my keys, or even for where I parked my car.
[Effect of swimming exercise on the expression of apelin and its receptor in pulmonary tissues of rats with hypoxic pulmonary hypertension]. (2012)

The improving effect of swimming exercise on hypoxic pulmonary hypertension in rats could be mediated by regulating the pulmonary apelin/APJ system.
ON THE INTENSITY-TIME RELATIONS FOR STIMULATION BY ELECTRIC CURRENTS. II (1932)

Hypotheses previously used (Blair, 1932) in deriving formulae for stimulation by direct currents are applied to other forms of electrical stimuli. This consists in considering solutions of the equation See PDF for Structure. where p is assumed to represent the local excitatory process, V is the voltage of the stimulus and K and k are constants. The solutions are discussed in regard to condenser discharges, linearly rising currents, exponentially rising currents, and alternating currents. New experimental work with alternating currents of frequencies above 400 per second on the sciatic gastrocnemius of the frog is related to the formulae.

Photogenotoxicity of Mammalian Cells: A Review of the Different Assays for In Vitro Testing¶ (2002)

During the past several years, phototoxicity has been studied at the molecular level, and these studies have provided new insights in the field of DNA lesion characterization, DNA repair and cell response to ultraviolet (UV)-induced stress. The development of new antibiotics and antiinflammatory drugs has highlighted the necessity to develop the assessment of phototoxicity in the safety evaluation of new chemical compounds. This paper aims at reviewing the known molecular mechanisms of the cellular response to UV-induced stress, the in vitro methods that can be proposed and used to screen for toxicity of sunlight and the photosensitization process resulting from the activation of drugs by light. UV sources, biological systems and endpoints of interest in that particular objective are listed. Phototoxic effects span from the cytotoxic-apoptotic effect to the induction of primary DNA damage, DNA repair and a variety of stress genes acting on the cell cycle and the fate of the cell. Ultimately, it can lead to the induction of hereditary DNA modification. A variety of assays are proposed to specifically address all these particular consequences of UV-induced toxicity.
Inflation-indexed bonds: how do they work? (1997)

In January 1997, the United States Treasury, after years of debate, issued its first inflation-indexed bonds. These securities differ from conventional bonds in that principal and interest payments are linked to a price index. Thus, the purchasing power of an investor's savings is protected from inflation. This article provides a simple description of the Treasury's new offering and discusses why indexed bonds may be useful to investors, the Treasury, and policymakers
New dimensions in endodontic imaging: part 1. Conventional and alternative radiographic systems (2009)

Conventional radiographs used for the management of endodontic problems yield limited information because of the two-dimensional nature of images produced, geometric distortion and anatomical noise. These factors often act in combination. This review paper assesses the limitations of periapical radiographs and seeks to clarify three-dimensional imaging techniques that have been suggested as adjuncts to conventional radiographs. These include tuned aperture computed tomography, magnetic resonance imaging, ultrasound, computed tomography and cone beam computed tomography (CBCT). Of these techniques, CBCT appears to be an effective and safe way to overcome some of the problems associated with conventional radiographs.
Charge equalization based-on three-level NPC converter for series connected battery strings (2009)

Abstract:- The main purpose of this paper is to design a charge equalization circuit for series connected lead-acid batteries. The charger utilizes a three-level neutral point clamped (NPC) AC/DC converter with voltage balance control to charge the series connected rechargeable battery strings. This paper details the operation principles of the charge equalization circuit under different operation modes and derives the governed equations. The proposed charge equalization circuit can not only regulate the power factor of AC source side, but also can balance the charge voltage for series connected rechargeable batteries. Finally, some simulation results are made to demonstrate the effectiveness of the charge equalization circuit scheme presented in this paper.
Canopeo: A Powerful New Tool for Measuring Fractional Green Canopy Cover (2015)

Fractional green canopy cover (FGCC) is a key diagnostic variable that can be used to estimate canopy development, light interception, and evapotranspiration partitioning. Available image analysis tools for quantifying FGCC are time‐consuming or expensive and cannot analyze video. Our objective was to develop a simple, accurate, and rapid tool to analyze FGCC from images and videos. This tool, called Canopeo, was developed using Matlab and is based on color ratios of red to green (R/G) and blue to green (B/G) and an excess green index (2G–R–B). The output from this tool was compared to that from two software packages widely used to analyze FGCC, SamplePoint, and SigmaScan Pro. Canopeo's image processing speed was 20 to 130 times faster than SigmaScan and 75 to 2500 times faster than SamplePoint. Canopeo correctly classified 90% of pixels when compared to SamplePoint. Root mean squared difference (RMSD) values for Canopeo FGCC vs. FGCC determined by SamplePoint and SigmaScan ranged from 0.04 to 0.12, with an average RMSD of 0.073 across several sets of images of corn ( Zea mays L.), forage sorghum [ Sorghum bicolor (L.) Moench], bermuda grass [ Cynodon dactylon (L.) Pers.], and switchgrass ( Panicum virgatum L.). Analysis of video recordings of transects over crop canopies proved to be useful to minimize sampling error and to quantify FGCC spatial variability. This analysis was simple and rapid with Canopeo but not possible with SamplePoint or SigmaScan. The Canopeo app for Matlab and for iOS and Android mobile devices can be downloaded at www.canopeoapp.com .
Joint chunk, power and bit allocation in multicast OFDMA system with average BER constraint (2012)

In this paper, resource allocation in multicast OFDMA system has been studied using joint chunk, power and bit allocation scheme. Multicasting is widely used in broadband wireless systems in which the same information is transmitted to many users at the same time while making minimum use of network resources. To reduce the complexity of the system resource allocation is carried out chunk by chunk. We propose an approach to maximize the overall throughput while decreasing the outage probability of the subcarriers. Numerical results show that in a multicast OFDMA system the throughput with joint chunk, power and bit allocation scheme is higher than the given chunk-based allocation scheme.

Pathological diagnosis of ovarian cancer (2012)

Case 1: Serous tubal cancer detected on PAP smear A 60 year old woman with a history of breast cancer was referred after malignant cells were found on PAP smear. Abdominal exam, cervical visualisation, transvaginal ultrasound and CT of the abdomen and pelvis were all normal. Endocervical and endometrial curettings demonstrated serous carcinoma cells consistent with tubal / ovarian origin. CA125 was slightly elevated at 53 (Upper Limit of Normal 35). At laparatomy uterus, fallopian tubes and ovaries appeared normal. She had a hysterectomy, bilateral salpingo-oophorectomy, omentectomy, peritoneal biopsies and washings. There was no macroscopic evidence of cancer, but microscopic examination confirmed serous cancer in the fimbrial end of the left fallopian tube(A) with scattered malignant cells in the lumen of both fallopian tubes(B), the omentum(C) and surface of the ovaries(D), surface of uterus and paracolic gutter. Washings were positive. Family history was unremarkable. BRCA mutation screening revealed a BRCA1 mutation. Despite intraperitoneal cisplatin and paclitaxel she relapsed and died 4 years later.
A Bayesian Hierarchical Approach to Ensemble Weather Forecasting (2010)

Summary In meteorology, the traditional approach to forecasting employs deterministic models mimicking atmospheric dynamics. Forecast uncertainty due to partial knowledge of the initial conditions is tackled by ensemble predictions systems. Probabilistic forecasting is a relatively new approach which may properly account for all sources of uncertainty. We propose a hierarchical Bayesian model which develops this idea and makes it possible to deal with ensemble predictions systems with non-identifiable members by using a suitable definition of the second level of the model. An application to Italian small-scale temperature data is shown.
Entropy-Suppressed Ferroelectricity in Hybrid Lead-Iodide Perovskites (2015)

The actual nature of the electric polarization in hybrid lead-iodide perovskites is unveiled on the basis of ab initio and model results. A finite, albeit small electric polarization of few μC/cm(2) is found to be pervasive in this system, due to the polar-uncompensated alignment of methylammonium dimers, at least for temperature lower than the activation energy of dimer rotations; however, the presence of a large number of structural local minima corresponding to differently oriented polarization directions counteracts the stabilization of an ordered ferroelectric phase at the macroscale. According to our estimate, only for temperatures lower than 40-50 K a clear ferroelectric behavior is displayed. At higher temperature the polarization is progressively suppressed and the ferroelectric ordering hindered by the large configurational entropy, giving rise to a superparaelectric-like behavior at the macroscale.
The tolkin gene is a tolloid/BMP-1 homologue that is essential for Drosophila development. (1995)

The Drosophila decapentaplegic (dpp) gene, a member of the transforming growth factor beta superfamily of growth factors, is critical for specification of the embryonic dorsal-ventral axis, for proper formation of the midgut, and for formation of Drosophila adult structures. The Drosophila tolloid gene has been shown to genetically interact with dpp. The genetic interactions between tolloid and dpp suggests a model in which the tolloid protein participates in a complex containing the DPP ligand, its protease serving to activate DPP, either directly or indirectly. We report here the identification and cloning of another Drosophila member of the tolloid/bone morphogenic protein (BMP) 1 family, tolkin, which is located 700 bp 5' to tolloid. Its overall structure is like tolloid, with an N-terminal metalloprotease domain, five complement subcomponents C1r/C1s, Uegf, and Bmp1 (CUB) repeats and two epidermal growth factor (EGF) repeats. Its expression pattern overlaps that of tolloid and dpp in early embryos and diverges in later stages. In larval tissues, both tolloid and tolkin are expressed uniformly in the imaginal disks. In the brain, both tolloid and tolkin are expressed in the outer proliferation center, whereas tolkin has another stripe of expression near the outer proliferation center. Analysis of lethal mutations in tolkin indicate it is vital during larval and pupal stages. Analysis of its mutant phenotypes and expression patterns suggests that its functions may be mostly independent of tolloid and dpp.
Optimized compressive sampling for passive millimeter-wave imaging (2012)

In this paper, we briefly describe a single detector passive millimeter-wave imaging system, which has been previously presented. The system uses a cyclic sensing matrix to acquire incoherent measurements of the observed scene and then reconstructs the image using a Bayesian approach. The cyclic nature of the sensing matrix allows for the design of a single unified and compact mask that provides all the required random masks in a convenient way, such that no mechanical mask exchange is needed. Based on this setup, we primarily propose the optimal adaptive selection of sampling submasks out of the full cyclic mask to obtain improved reconstruction results. The reconstructed images show the feasibility of the imaging system as well as its improved performance through the proposed sampling scheme.
