Curvelet-based method for orientation estimation of particles
2013
A method based on the curvelet transform is introduced for estimating from two-dimensional images the orientation distribution of small anisotropic particles. Orientation of fibers in paper is considered as a particular application of the method. Theoretical aspects of the suitability of this method are discussed and its efficiency is demonstrated with simulated and real images of fibrous systems. Comparison is made with two traditionally used methods of orientation analysis, and the new curvelet-based method is shown to perform clearly better than these traditional methods.
Phantom/liminal fat and feminist theories of the body
2017
This article brings together two concepts, ‘phantom fat’ and ‘liminal fat’, which both aim to grasp how fat in contemporary culture becomes a kind of material immateriality, corporeality in suspension. Comparing the spheres of representation and experience, we examine the challenges and usefulness of these concepts, and feminist fat studies perspectives more broadly, to feminist scholarship on the body. We ask what connects and disconnects fat corporeality and fat studies from ways of theorising other embodied differences, like gender, ‘race’, disability, class and sexuality, especially when thinking through their perceived mutability or removability, and assumptions about their relevance …
An Atypical Case of Taravana Syndrome in a Breath-Hold Underwater Fishing Champion: A Case Report
2013
Dysbaric accidents are usually referred to compressed air-supplied diving. Nonetheless, some cases of decompression illness are known to have occurred among breath-hold (BH) divers also, and they are reported in the medical literature. A male BH diver (57 years old), underwater fishing champion, presented neurological disorders as dizziness, sensory numbness, blurred vision, and left frontoparietal pain after many dives to a 30–35 meters sea water depth with short surface intervals. Symptoms spontaneously regressed and the patient came back home. The following morning, pain and neurological impairment occurred again and the diver went by himself to the hospital where he had a generalized to…
Non-stationary dynamo and magnetospheric accretion processes of the classical T Tauri star V2129 Oph
2011
We report here the first results of a multiwavelength campaign focussing on magnetospheric accretion processes of the classical T Tauri star V2129 Oph. In this paper, we present spectropolarimetric observations collected in 2009 July with ESPaDOnS at the Canada-France-Hawaii Telescope and contemporaneous photometry secured with the SMARTS facility. Circularly polarized Zeeman signatures are clearly detected, both in photospheric absorption and accretion-powered emission lines, from time-series of which we reconstruct new maps of the magnetic field, photospheric brightness and accretion-powered emission at the surface of V2129 Oph using our newest tomographic imaging tool - to be compared wi…
High-Frequency and Ultra-High Frequency Ultrasound: Musculoskeletal Imaging up to 70 MHz
2020
AbstractMusculoskeletal (MSK) ultrasound has well-established advantages, able to investigate very small structures with high resolution and a quick and real-time dynamic evaluation with the possibility of contralateral comparison. Thus ultrasound has kept its own almost exclusive fields of application in daily clinical practice, and it is considered the first-level imaging technique to assess tendons, bursae, and capsuloligamentous structures of small peripheral joints as well as peripheral nerves. Up to now, however, clinical MSK ultrasound imaging could not go beyond the first 1 to 2 cm under the skin, using high-frequency probes up to 18 to 20 MHz with spatial resolution just below mill…
Psicothema
2014
Resumen tomado de la publicación Características psicométricas de la versión española del Cuestionario sobre la Práctica en Imaginación en el Deporte. Antecedentes: la presente investigación describe las características psicométricas de la versión española del cuestionario sobre la práctica en imaginación en el deporte que evalúa funciones cognitivas y motivacionales del uso de la imaginación. Método: el estudio se realizó en una muestra de 361 deportistas (234 hombres y 127 mujeres) con una media de edad de 24.29 ± 7.76 años. Los deportistas competían en 31 modalidades a nivel regional, nacional o internacional. Resultados: un análisis confirmatorio inicial representando un modelo de cinco…
GLOBAL ISSUES, WESTERN FOCI: BANAL OCCIDENTALISM IN A FINNISH NEWSPAPER
2016
‘The West’ is an imagined community par excellence with a plethora of connotations that often contradict each other. Although it is often not at all certain exactly what the West or things Western refer to, the concepts are used as if there was some distinct cultural reality corresponding to them. Like any other ethnic group, tribe, nation state, or even village, the West is both fantasy and real, a social construction and, to some extent, an observable social formation. The Western world exists because people believe in its unity and share the connotations but also for a more mundane—or banal— reason: because these are constantly expressed in text and speech. This article examines the news…
POLITICAL THEORY'S IMAGINATION. A FEW REMARKS ON WIKTOR MARZEC BOOK
2017
Social sciences, understood as critical and not neutral by nature, they should be equipped with specific competencies and sensivity. C. W. Mills these comptence define as sociological imagination – which is study of the relationship of history and biography, Giddens interpreted it as three basic senses: historical, anthropological, critical. The translation into political science would be a political theories imagination, it consist,, among over things like a: historicity of political phenomena, antisubstansialism, research self-awareness. Definition of political theories imagination I propose in the context of Wiktor Marzec’s paper Rebelion and Reaction, which is a study from field of his…
Decagram-Scale Synthesis of Multicolor Carbon Nanodots: Self-Tracking Nanoheaters with Inherent and Selective Anticancer Properties
2022
Carbon nanodots (CDs) are a new class of carbon-based nanoparticles endowed with photoluminescence, high specific surface area, and good photothermal conversion, which have spearheaded many breakthroughs in medicine, especially in drug delivery and cancer theranostics. However, the tight control of their structural, optical, and biological properties and the synthesis scale-up have been very difficult so far. Here, we report for the first time an efficient protocol for the one-step synthesis of decagram-scale quantities of N,S-doped CDs with a narrow size distribution, along with a single nanostructure multicolor emission, high near-infrared (NIR) photothermal conversion efficiency, and sel…
