Proyección y reivindicación de los poetas yahilíes en la poesía árabe contemporánea.
2001
Veglison Elias de Molins, Josefina - Josefina.Veglison@uv.es Este articulo analiza las referencias a poetas de la Yahiliyya presentes en la poesía árabe contemporánea en calidad de mitos y arquetipos. Cabe destacar el hecho de que éstos sean beduinos pertenecientes a la categoría de autores de mu'allaqa o al grupo de poetas bandoleros (sa'álik). El autor contemporáneo rescata sus figuras porque interpreta como signo de modernidad su talante innovador y su rebeldía contra la norma, tanto en lo formal como en los contenidos. Esta reivindicación se lleva a cabo, en los contenidos, mediante la evocación de sus nombres en poemas o títulos de diwanes, la inclusión de sus versos o la réplica a sus…
Evaluación morfológica y morfométrica de neuroimágenes retinianas y cerebrales como factor pronóstico de la función visual en pacientes con esclerosi…
2013
El propósito de esta tesis doctoral es estudiar la proporción de pérdida neurológica en el tiempo a nivel cerebral y retiniano en relación con la deficiencia sensorial y motora en pacientes diagnosticados de esclerosis múltiple. La muestra está constituida por 35 pacientes clasificados en tres grupos en función del subtipo de enfermedad (síndromes clínicos aislados, formas remitentes-recurrentes y formas progresivas) diagnosticados de esclerosis múltiple según los criterios de McDonald, aunque a efectos del análisis estadístico, las unidades de observación fueron los 70 ojos correspondientes. Se recopiló información mediante la anamnesis y revisión de la historia clínica de los pacientes re…
A Domain Imbedding Method with Distributed Lagrange Multipliers for Acoustic Scattering Problems
2003
The numerical computation of acoustic scattering by bounded twodimensional obstacles is considered. A domain imbedding method with Lagrange multipliers is introduced for the solution of the Helmholtz equation with a second-order absorbing boundary condition. Distributed Lagrange multipliers are used to enforce the Dirichlet boundary condition on the scatterer. The saddle-point problem arising from the conforming finite element discretization is iteratively solved by the GMRES method with a block triangular preconditioner. Numerical experiments are performed with a disc and a semi-open cavity as scatterers.
Allogeneic Stem Cell Transplant Versus Tandem High-Dose Melphalan for Front-Line Treatment of Deletion 13q14 Myeloma – An Interim Analysis of the Ger…
2009
Abstract Abstract 51 Background Allogeneic stem cell transplantation (allo SCT), a treatment modality based on transfer of immunocompetent donor lymphocytes offers curative potential to subjects with a variety of hematological cancers. In multiple myeloma (MM), high-dose melphalan followed by autologous stem cell transplantation (auto SCT) is adopted as a standard of care. However, it remains palliative since virtually all patients (pts) relapse and renders allo SCT an option of interest. Deletion of chromosome 13q14 (13q-) in MM has been shown to negatively impact prognosis. Therefore, improvement of therapy for 13q- pts is highly desirable. Patients and methods A prospective two-arm multi…
Sezernierter Interleukin-2-Rezeptor als Aktivitätsparameter der Sarkoidose*
2008
Serum sIL-2-R levels were measured in 28 sarcoidosis patients at multiple time points before, during, and after therapy, with a mean follow-up time of 10.2 +/- 5.2 months, and the results compared with the clinical activity of the disease. Before therapy, 20 out of 24 episodes with active disease exhibited elevated levels of sIL-2-R (918 +/- 362 U/ml). In inactive disease after tapering off corticoid therapy the sIL-2-R levels were 453 +/- 274 U/ml. Disease activity under therapy also correlated with sIL-2-R serum levels. 23 out of 29 episodes with signs of activity under therapy had elevated sIL-2-R levels (808 +/- 409 U/ml). Only three of 28 patients in whom disease activity ceased after …
Persistent inflammation alters the function of the endogenous brain stem cell compartment
2008
Endogenous neural stem/precursor cells (NPCs) are considered a functional reservoir for promoting tissue homeostasis and repair after injury, therefore regenerative strategies that mobilize these cells have recently been proposed. Despite evidence of increased neurogenesis upon acute inflammatory insults (e.g. ischaemic stroke), the plasticity of the endogenous brain stem cell compartment in chronic CNS inflammatory disorders remains poorly characterized. Here we show that persistent brain inflammation, induced by immune cells targeting myelin, extensively alters the proliferative and migratory properties of subventricular zone (SVZ)-resident NPCs in vivo leading to significant accumulation…
Wireless ECG and cardiac monitoring systems: State of the art, available commercial devices and useful electronic components
2021
Abstract Wireless ElectroCardioGram (ECG) systems are employed in manifold application fields: tele-monitoring, sport applications, support to ageing people at home, fetal ECG, wearable devices and ambulatory monitoring. The presence of cables often hinders user’s free movements, alongside clinicians’ routine operations. Therefore, wireless ECG systems are desirable. This paper aims at reviewing the solutions described in the literature, besides commercially available devices and electronic components useful to setup laboratory prototypes. Several systems have been developed, different in terms of the adopted technology; when approaching the development of a wireless ECG system, some import…
Response to Stanich et al.: Correspondence regarding-PTEN hamartoma tumor syndromes in childhood-Description of two cases and a proposal for follow-u…
2014
The follow-up protocol, which we describe in this study can serve as a practical proposal for clinicians, and as a basis for future studies. We strongly urge the clinician to start an early surveillance of the gastrointestinal tract including regular endoscopy. The main management goals in PHTS patients are to detect colon cancer early, and to prevent polyp-related complications (bowel obstruction from intussusception). The presence of multiple nonmalignant polyps in patients with PTEN mutations may complicate noninvasive methods of colon evaluation [Tan et al., 2012]. In addition, there is a high variability in severity of polyps progression, and the malignant potential of these lesions is…
An Adaptive Alternating Direction Method of Multipliers
2021
AbstractThe alternating direction method of multipliers (ADMM) is a powerful splitting algorithm for linearly constrained convex optimization problems. In view of its popularity and applicability, a growing attention is drawn toward the ADMM in nonconvex settings. Recent studies of minimization problems for nonconvex functions include various combinations of assumptions on the objective function including, in particular, a Lipschitz gradient assumption. We consider the case where the objective is the sum of a strongly convex function and a weakly convex function. To this end, we present and study an adaptive version of the ADMM which incorporates generalized notions of convexity and penalty…
Two-dimensional single- and multiple-quantum correlation spectroscopy in zero-field nuclear magnetic resonance.
2020
We present single- and multiple-quantum correlation $J$-spectroscopy detected in zero ($<\!\!1$~$\mu$G) magnetic field using a \Rb vapor-cell magnetometer. At zero field the spectrum of ethanol appears as a mixture of \carbon isotopomers, and correlation spectroscopy is useful in separating the two composite spectra. We also identify and observe the zero-field equivalent of a double-quantum transition in ${}^{13}$C$_2$-acetic acid, and show that such transitions are of use in spectral assignment. Two-dimensional spectroscopy further improves the high resolution attained in zero-field NMR since selection rules on the coherence-transfer pathways allow for the separation of otherwise overlappi…
