WeDoCWT: A New Method for Web Document Clustering Using Discrete Wavelet Transforms

Organizing web information is an important aspect of finding information in the easiest and most efficient way. We present a new method for web document clustering called WeDoCWT, which exploits the discrete wavelet transform and term signal, to improve the document representation. We studied different methods for document segmentation to construct the term signals. We used two datasets, UW-CAN and WebKB, to evaluate the proposed method. The experimental results indicated that dividing the documents into fixed segments is preferable to dividing them into logical segments based on HTML features because the web pages do not have the same structure. Mean TF–IDF reduction technique gives the best results in most cases. WeDoCWT gives F-measure better than most of the previous approaches described in the literature. We used Munkres assignment algorithm to assign each produced cluster to the original class in order to evaluate the clustering results.
Pharmacogenetic rescue in time and space of the rutabaga memory impairment by using Gene-Switch

The GAL4-based Gene-Switch system has been engineered to regulate transgene expression in Drosophila in both time and space. We constructed a Gene-Switch transgene in which Gene-Switch expression is restricted spatially by a defined mushroom body enhancer. This system allows Gene-Switch to be active only in the mushroom bodies and only on administration of the pharmacological Gene-Switch ligand RU486. This line was used to drive the expression of a rutabaga cDNA in otherwise rutabaga mutant flies. Induction of the rutabaga cDNA in the mushroom bodies only during adulthood, or during adulthood along with the larval and pupal developmental stages, corrects the olfactory memory impairment found in rutabaga mutants. Induction of the cDNA only during the larval and pupal stages was inconsequential to performance in olfactory memory tasks. These data indicate that normal rutabaga function must be expressed in adulthood for normal memory and conclusively delimit the time and space expression requirements for correcting the rutabaga memory impairment. Such combined pharmacogenetic regulation of transgene expression now allows this time and space dissection to be made for other behavioral mutants.
Recurrent ovarian cancer. Effective radiotherapeutic palliation after chemotherapy failure

Background. Recurrent ovarian cancer after frontline chemotherapy is incurable; however, palliation of focal lesions often is needed to alleviate symptoms. Because published response rates to palliative irradiation (RT) among patients failing cisplatin‐based chemotherapy are scarce, the authors attempted to define the palliative role of radiotherapy for symptomatic, localized ovarian cancer recurrences. Factors predicting a response to RT also were sought.
Acupuncture and temporomandibular disorders: a 3-month follow-up EMG study.

OBJECTIVES The purpose of this study was to investigate the levels of electromyographic (EMG) activation and maximal molar bite force before and after a 3-month acupuncture therapy in individuals with temporomandibular disorder (Helkimo Index) from a pool of subjects attending the Special Care Course of the Ribeirão Preto Dental School, São Paulo University, Brazil. DESIGN All 17 patients, aged between 37 and 50 years (44.2 +/- 4.84 years), with an average weight of 71 +/- 9.45 kg and height of 1.64 +/- 0.07 m, were clinically examined with regard to pain and dysfunctions of the masticatory system. The temporomandibular acupuncture points of needling were IG4, E6, E7, B2, VB14, VB20, ID18, ID19, F3, E36, VB34, E44, R3, and HN3. EMG measures were acquired before and after the treatment using a MyoSystem-BR1 electromyographer. The data collected at rest, protrusion, left and right laterality, and clenching were normalized by maximum voluntary contraction. Maximal bite force in right and left molar regions were registered using a dynamometer with a capacity of up to 1000 N, adapted for oral conditions. The highest value out of three recordings was considered to be the individual's maximal bite force. The results were statistically analyzed using the paired t test (SPSS version 15.0) during the comparison before and after treatment. RESULTS We found decreased EMG activity at rest, protrusion, left and right laterality, and clenching; as well as increased values of maximal bite force after acupuncture treatment. CONCLUSIONS Acupuncture promoted alterations in the EMG activity of masticatory muscles, increased maximal molar bite force, and led to remission of the subjects' painful symptomatology.
Tie Persistence in Academic Social Networks

This paper attempts to shed light on the importance of some social academic-related factors in determining the strength of links in academic social networks. Our purpose is to assess the extent to which the frequency of the tie, the closeness between its actors, and the scientific contributions of the actors in the tie can affect the scientific collaboration relationship between them. We propose a model that relies on this three link strength indicators in order to predict the tie persistence in academic social networks. We experimented the model on a social network extracted from the DBLP computer science bibliographic network. We compared the output of the model with that of the link prediction baseline methods. The results show better performance of the proposed model.
Accuracy of clinical and ultrasound estimation of fetal weight in predicting actual birth weight in Enugu, Southeastern Nigeria.

BACKGROUND Estimation of fetal weight is important for antenatal and intrapartum management of pregnant women. Sonographic methods are not readily accessible in under-resourced settings, it is therefore necessary to study the accuracy of a clinical method of estimating fetal weight where this limitation (unavailability of ultrasound) exists. OBJECTIVE To compare the accuracy of clinical and ultrasound methods of fetal weight estimation at term. MATERIALS AND METHODS Clinical and ultrasound fetal weights were estimated on 200 consecutive term pregnancies (37 completed weeks of gestation - 41 weeks and 6 days) at the University of Nigeria Teaching Hospital, Enugu, Nigeria from 1 st April to 30 th November 2012. Accuracy was determined using percentage error, absolute percentage error, and proportion of estimates within 10% of actual birth weight. RESULTS Actual birth weight had strong positive correlation with both clinical and ultrasound estimated fetal weights (r = 0.71, P < 0.001 and r = 0.69, P < 0.001, respectively). Overall, both the clinical and ultrasound methods systematically overestimated the actual birth weight. The proportion of the clinical estimated weights that were within 10% of the actual birth weight was significantly lower than that of ultrasound method for babies of all birth weights (35.0 vs. 67.5%; P < 0.001) and for macrosomic babies (76 vs 100%, P = 0.009). For babies with normal birth weights (2.5-3.9 kg), ultrasound method error values were significantly lower than those of clinical method for both the mean % error (5.4 vs 19.6%; P < 0.001) and the mean absolute % error (9.97 vs 20.6%; P < 0.001). CONCLUSION The ultrasound method is generally a better predictor of the actual birth weight than the clinical method, and thus should be used in estimating the actual birth weight when accessible.
AN IN VITRO SYSTEM FOR THE STUDY OF THE MECHANISM OF ANTIGENIC STIMULATION IN THE SECONDARY RESPONSE.

The uptake of [14C]thymidine by spleen cell suspensions from rabbits previously immunized to heterologous serum proteins is stimulated by the addition of antigen in vitro. This stimulation is specific and dependent upon concentration of antigen. It represents an increased rate of DNA synthesis and cell division by certain cells of the suspension. These cells are large undifferentiated mononuclear cells comprising approximately 1 per cent of the total population. It is suggested that this response is the in vitro counterpart of the cellular proliferation seen in whole animals following the re-injection of antigen. The procedure described provides a quantitative system for the study of the mechanism of antigenic stimulation. Some preliminary experiments are reported.
Performance assessment of technology transfer project: An application of DEA technique

Technology transfer is a mechanism to acquire technology and helps company to enhance their technology capabilities. The purpose of this study is to demonstrate how Data Envelopment Analysis (DEA) can be used to assess performance of technology transfer project at firm level. Data collected from transferring the robotics operating technology project of 12 automotive parts/components manufacturing companies are examined by using the DEA model. The results of this study show that six companies carried out efficient technology transferring. The average efficiency score of technology transfer project is 93.3%. This finding confirms that absorptive capacity of recipient firms is a critical success factor underlying differences between efficient and inefficient firms. DEA method provides Chief Technology Officers (CTO) or project leaders a framework to determine appropriate transferring mechanisms and necessary internal and external resources.
Observation of resonance fluorescence and the Mollow triplet from a coherently driven site-controlled quantum dot

Resonant excitation of solid state quantum emitters has the potential to deterministically excite a localized exciton while ensuring maximally coherent emission. In this work, we demonstrate the coherent coupling of an exciton localized in a lithographically positioned, site-controlled semiconductor quantum dot to an external resonant laser field. For strong continuous-wave driving we observe the characteristic Mollow triplet and analyze the Rabi splitting and sideband widths as a function of driving strength and temperature. The sideband widths increase linearly with temperature and the square of the driving strength, which we explain via coupling of the exciton to longitudinal acoustic phonons. We also find an increase of the Rabi splitting with temperature, which indicates a temperature-induced delocalization of the excitonic wave function resulting in an increase of the oscillator strength. Finally, we demonstrate coherent control of the exciton excited state population via pulsed resonant excitation and observe a damping of the Rabi oscillations with increasing pulse area, which is consistent with our exciton–photon coupling model. We believe that our work outlines the possibility to implement fully scalable platforms of solid state quantum emitters. Such scalability is one of the key prerequisites for more advanced, integrated nanophotonic quantum circuits.
Performance Comparison Between Bulk and SOI Junctionless Transistors

The design and characteristics of a junctionless (JL) bulk FinFET were compared with the silicon-on-insulator (SOI) JL nanowire transistor (JNT) using 3-D quantum transport device simulation. The JL bulk FinFET exhibits a favorable on/offcurrent ratio and short-channel characteristics by reducing the effective channel thickness that is caused by the channel/substrate junction. The drain-induced barrier lowering and the subthreshold slope are about 40 mV and 73 mV/dec, respectively, with an on/offcurrent ratio of 10<sup>5</sup> at <i>W</i> = 10 nm. The JL bulk FinFET is less sensitive to the channel thickness than the SOI JNT. Furthermore, the threshold voltage <i>V</i><sub>th</sub> of the JL bulk FinFET can be easily tuned by varying substrate doping concentration <i>N</i><sub>sub</sub>. The modulation range of <i>V</i><sub>th</sub> as <i>N</i><sub>sub</sub> changes from 10<sup>18</sup> to 10<sup>19</sup> cm<sup>-3</sup>, which is around 30%.
Variation in Inflammatory and Early Onset Breast Cancer Incidence and Survival by Geography, Socioeconomic Position, and Tumor Characteristics.

ed by SEER registries. In cases where assay results were reported for more than one tumor specimen, the highest value was recorded (if any sample is positive, the receptor is recorded as positive). SEER abstractors record assay results from tumor specimens prior to receipt of neoadjuvant therapy, although if not available, posttreatment results are reported. Cases where either assay was not ordered or performed, borderline and undetermined whether positive or negative, ordered – results not in chart, or where there was no documentation/information in the patient record were excluded (22). Although excluding cases where hormone receptor status is missing may potentially introduce selection bias, the large majority of cases (82%) had hormone receptor status recorded. Grade was dichotomized into low grade (well differentiated grade I and moderately differentiated grade II tumors) vs. high grade tumors (poorly differentiated grade III and undifferentiated; anaplastic grade IV tumors). County-Level Measures Three county-level measures of SEP derived from the 1990 and 2000 US censuses were used in this analysis (23). For both the 1990 and 2000 census, the percent of persons below the poverty level within a county was dichotomized to 20%. The 1990 poverty level and census result was applied to all cases diagnosed from 1990- 1999, while the 2000 poverty level and census result was applied to cases diagnosed from
44-plex cytokine profile of cholesteatoma

Abstract Conclusion: A nuanced profiling was achieved by the simultaneous analysis of 44 cytokines in cholesteatoma. The novel discovery of high levels of interleukin 21 (IL21) in cholesteatoma could explain the expansive growth and could serve as future drug target, as for example also suggested for psoriasis. Objective: The aim of this study was to analyze and compare the cytokine profiles of cholesteatoma and the surrounding tissues. Methods: The Luminex Multiplex xMAP bead-based antibody assay was applied to measure the concentrations of 44 cytokines, chemokines, and growth factors (BIRC5, CCL11, CCL2, CCL3, CCL4, CCL5, CCL7, CD40LG, CSF2, CSF3, CX3CL1, CXCL10, CXCL9, EGF, HGF, ICAM1, IFNA2, IFNG, IL10, IL12*, IL12B, IL13, IL15, IL17A, IL17F, IL1A, IL1B, IL1R1, IL2, IL20, IL21, IL22, IL23A, IL4, IL5, IL6, IL7, IL8, LTA, MIF, TGFA, TGFB1, TNF, VEGFA) in human biopsies from cholesteatoma, neck of cholesteatoma (the transition zone from tympanic membrane), tympanic membrane, external auditory canal skin, and middle ear mucosa. Results: All 44 cytokines were detected in all 5 tissue types. Compared with external auditory canal skin, cholesteatoma showed high levels of IL8 (ratio 38, p = 0.027) and IL-21 (ratio 4.1, p = 0.02) and low levels of IL-6 (ratio 0.07, p = 0.027).
Transformation of Schwanniomyces occidentalis with an ADE2 gene cloned from S. occidentalis

We have developed an efficient transformation system for the industrial yeast Schwanniomyces occidentalis (formerly Schwanniomyces castellii). The transformation system is based on ade2 mutants of S. occidentalis deficient for phosphoribosylaminoimidazole carboxylase that were generated by mutagenesis. As a selectable marker, we isolated and characterized the S. occidentalis ADE2 gene by complementation in an ade2 strain of Saccharomyces cerevisiae. S. occidentalis was transformed with the recombinant plasmid pADE, consisting of a 4.5-kilobase-pair (kbp) DNA fragment from S. occidentalis containing the ADE2 gene inserted into the S. cerevisiae expression vector pYcDE8 by a modification of the spheroplasting procedure of Beggs (J. D. Beggs, Nature [London] 275:104-108, 1978). Intact plasmids were recovered in Escherichia coli from whole-cell lysates of ADE+ transformants, indicating that plasmids were replicating autonomously. High-molecular-mass species of pADE2 were found by Southern hybridization analysis of intact genomic DNA preparations. The shift to higher molecular mass of these plasmids during electrophoresis in the presence ethidium bromide after exposure to shortwave UV suggests that they exist in a supercoiled form in the transformed host. Subclones of the 4.5-kbp insert indicated that ADE2-complementing activity and sequences conferring autonomous replication in S. occidentalis were located within a 2.7-kbp EcoRI-SphI fragment. Plasmids containing this region cloned into the bacterial vector pUC19 complemented ade2 mutants of S. occidentalis with efficiencies identical to those of the original plasmid pADE.
Hate Crimes and Stigma-Related Experiences Among Sexual Minority Adults in the United States

Using survey responses collected via the Internet from a U.S. national probability sample of gay, lesbian, and bisexual adults (N = 662), this article reports prevalence estimates of criminal victimization and related experiences based on the target's sexual orientation. Approximately 20% of respondents reported having experienced a person or property crime based on their sexual orientation; about half had experienced verbal harassment, and more than 1 in 10 reported having experienced employment or housing discrimination. Gay men were significantly more likely than lesbians or bisexuals to experience violence and property crimes. Employment and housing discrimination were significantly more likely among gay men and lesbians than among bisexual men and women. Implications for future research and policy are discussed.

The Elderly who Live Alone Their Mental Health and Social Relationships

In a community survey of the elderly in Hobart, persons who lived alone were compared to those who lived with others. Those who lived alone were more often widows and had had more education. They had markedly fewer close relationships but as much other social interaction. They reported that their personal networks were as adequate as other elderly persons, yet they experienced much more loneliness. They had no higher a prevalence of depressive disorders or dementia on DSM-III criteria, but they did have a higher frequency of neurotic depression and some depressive symptoms, of which loneliness was one. Contrary to what might intuitively be expected, the elderly who live alone may not be a group at increased risk for formal psychiatric morbidity. Instead, they may have a moderate excess of dysphoric symptoms.
Peri-Implantation Hormonal Milieu: Elucidating Mechanisms of Abnormal Placentation and Fetal Growth1

ABSTRACT Assisted reproductive technologies (ART) have been associated with several adverse perinatal outcomes involving placentation and fetal growth. It is critical to examine each intervention individually in order to assess its relationship to the described adverse perinatal outcomes. One intervention ubiquitously used in ART is superovulation with gonadotropins. Superovulation results in significant changes in the hormonal milieu, which persist during the peri-implantation and early placentation periods. Epidemiologic evidence suggests that the treatment-induced peri-implantation maternal environment plays a critical role in perinatal outcomes. In this study, using the mouse model, we have isolated the exposure to the peri-implantation period, and we examine the effect of superovulation on placentation and fetal growth. We report that the nonphysiologic peri-implantation maternal hormonal environment resulting from gonadotropin stimulation appears to have a direct effect on fetal growth, trophoblast differentiation, and gene expression. This appears to be mediated, at least in part, through trophoblast expansion and invasion. Although the specific molecular and cellular mechanism(s) leading to these observations remain to be elucidated, identifying this modifiable risk factor will not only allow us to improve perinatal outcomes with ART, but help us understand the pathophysiology contributing to these outcomes.

Laminar‐specific encoding of texture elements in rat barrel cortex

For rats texture discrimination is signalled by the large face whiskers by stick‐slip events. Neural encoding of repetitive stick‐slip events will be influenced by intrinsic properties of adaptation. We show that texture coding in the barrel cortex is laminar specific and follows a power function. Our results also show layer 2 codes for novel feature elements via robust firing rates and temporal fidelity. We conclude that texture coding relies on a subtle neural ensemble to provide important object information.
EVOLUTION OF WILD SHEEP IN IRAN

The genus Ovis, which includes all true sheep, constitutes one of the more complicated mammalian genera relative to its evolution and systematics. Wild sheep presently range from Europe (originally confined to Corsica and Sardinia in the Holocene, but now widely introduced in mainland Europe) through xeric and subxeric regions of the Middle East, Soviet Turkmenistan, the Indian Subcontinent, Central Asia, and Siberia. In North America, wild sheep range from Alaska to northern Mexico. Various authors (Lydekker, 1913; Nasonov, 1923; Tsalkin, 1951; Haltenorth, 1963) have recognized from one to nine species. A major obstacle in clarifying the systematics of Ovis arises from the diverse phenotypic variability exhibited throughout its wide Holarctic distribution. Iran, perhaps, presents the most complicated area relative to the evolution of wild sheep. Wild sheep occur throughout Iran except in forest, tall grass, and tall shrub regions; the animals prefer open, undulating montane habitat. In no other known area of comparable size do wild sheep exhibit as much phenotypic and chromosomal variation. Early authors (Lydekker, 1913; Nasonov, 1923) recognized three species in Iran. Recent studies (Nadler et al., 1971, 1973a) in northern Iran have greatly clarified the systematics of wild sheep in this area. They revealed the existence of two cytologically distinct populations with diploid (2N) chromosome numbers of 58 in northeastern Iran and 2N = 54 in northwestern Iran. Where these cytotypes converged in the Alborz (Elburz) Mountains of northern Iran, a hybrid zone existed with numerically heterogeneous karyotypes of 2N 54, 55, 56, 57 and 58. This paper further describes the chromosomes of wild sheep from the hybrid zone of the Central Alborz Mountains originally described by Nadler et al. (1971) and from other populations of wild sheep in southern Iran. In addition serological, morphological, ecological, and reproductive data are related to chromosomal characters and these lines of evidence are combined to clarify further the evolution of Iranian wild sheep.
