Relationship between wave processes in sunspots and quasi-periodic pulsations in active region flares
Get PDFA phenomenological relationship between oscillations in a sunspot and quasi-periodic pulsations (QPP) in flaring energy releases at an active region (AR) above the sunspot is established. The analysis of the microwave emission recorded by the Nobeyama Radioheliograph at 17 GHz shows a gradual increase in the power of the 3-min oscillation train in the sunspot associated with AR 10756 before flares in this AR. The flaring light curves are found to be bursty with a period of 3 min. Our analysis of the spatial distribution of the 3-min oscillation power implies that the oscillations follow from sunspots along coronal loops towards the flaring site. It is proposed that QPP in the flaring energy releases can be triggered by 3-min slow magnetoacoustic waves leaking from sunspots
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
The cytosolic SycE and SycH chaperones of Yersinia protect the region of YopE and YopH involved in translocation across eukaryotic cell membranes
No full textYersinia adhering at the surface of eukaryotic cells secrete a set of proteins called Yops. This secretion which occurs via a type III secretion pathway is immediately followed by the injection of some Yops into the cytosol of eukaryotic cells. Translocation of YopE and YopH across the eukaryotic cell membranes requires the presence of the translocators YopB and YopD. YopE and YopH are modular proteins composed of an N-terminal secretion signal, an internalization domain, and an effector domain. Secretion of YopE and YopH requires the presence of the specific cytosolic chaperones SycE and SycH, respectively. In this work, we have mapped the regions of YopE and YopH that are involved in binding of their cognate chaperone. There is only one Syc-binding domain in YopE (residues 15-50) and YopH (residues 20-70). This domain is localized immediately after the secretion signal and it corresponds to the internalization domain. Removal of this bifunctional domain did not affect secretion of YopE and YopH and even suppressed the need for the chaperone in the secretion process. Thus SycE and SycH are not secretion pilots. Instead, we propose that they prevent intrabacterial interaction of YopE and YopH with proteins involved in translocation of these Yops across eukaryotic cell membranes

A comparison of medical and physical therapies in the management of facial arthromyalgia (temporomandibular joint dysfunction).
No full textThis thesis reports on a randomised controlled trial of medical and physical therapy in the management of chronic temporomandibular joint pain and dysfunction. The literature review first explores the meaning and measurement of chronic pain. The anatomy and dynamic function of the temporomandibular joint and associated musculature is then introduced before describing the pain and dysfunction which affects this specific region. The development of terminology, classification and epidemiology is addressed to provide a basis for understanding the condition. A discussion of the presumed multifactorial aetiology and current management follows, with focus on the two areas of specific interest in this study the physical and medical therapies The study methods, results and discussion are presented in accordance with the CONSORT (Consolidated Standards of Reporting Trials) guidelines. A referral cohort of 1,038 subjects were screened and assessed. 250 subjects met inclusion criteria and agreed to participate with informed consent. Subjects were randomised into four groups: medical therapy, placebo, occlusal bite guard, medical therapy and occlusal bite guard. A three month treatment phase and a six month follow-up phase were then conducted. The first section of the results examines the referral cohort. Demographic, clinical diagnostic, and psychosocial profile are reported with treatment uptake for the trial. The second section examines the three month trial phase, treatment efficacy and outcome. The analysis of subgroups is explored, including the characteristics of responders and non-responders to therapy in addition to outcome measures in subjects with initially high pain scores and high levels of depression. The final section analyses reasons for patient withdrawal and non compliance before examining the follow up phase post therapy for maintenance of improvement. Both primary and secondary outcome measures revealed significant improvement in pain amongst all four groups which was maintained during the follow-up phase
