One body, many heads; the Cerberus of catalysis. A new multipurpose in-situ cell for XAS at ALBA
No full textA new multi-purpose in-situ cell and its control system have been developed for
synchrotron-based techniques as are X-Ray Absorption spectroscopy (XAS) and X-Ray
Diffraction (XRD). The cell is made of a stainless steel body and three different
exchangeable heads to tackle different scientific areas that include solid-gas catalysis, solidliquid catalysis and electrocatalysis. The different versions of the cell are herein described and their functionality is exemplified by some case studies.Guilera, G.; Rey Garcia, F.; Hernandez Fenollosa, J.; Cortés Vergaz, JJ. (2013).

The vanishing author in computer-generated works: a critical analysis of recent Australian case law
No full textAbstract
The use of software is ubiquitous in the creation of many copyright works, yet the requirement in copyright law that every work have a human author who engages in independent intellectual effort means that its use may prevent copyright subsistence. Several recent Australian cases have refocused attention on authorship as an essential criterion of copyright subsistence, and these cases suggest that much computer-produced output may be authorless and thus lack copyright protection. This article, the first in a two-part series, analyses how each case deals with the question of authorship of computer-produced works and why the use of software diminishes copyright protection for a significant number of computer-generated works. The article critiques the application of conventional notions of human authorship developed in the pre-computer age to modern productions and suggests alternative approaches to authorship that satisfy both the major objectives of copyright policy and the need to adapt to the computer age. The article argues that, without a broader judicial approach to authorship of computer-generated works, Parliament must remedy the lacuna in protection for these ‘authorless’ works. Possible solutions for reform are suggested. In a forthcoming article, the author comprehensively examines those reform proposals

Cefalea y otros efectos adversos de la mielografía por punción lumbar
No full textResumenObjetivo: Determinar la frecuencia y distribución en el tiempo de los efectos adversos de la mielografía por punción lumbar (MPL) y con base en nuestra experiencia y en la literatura, la relación existente entre la cefalea posterior a la mielografía (CPM) con variablesque dependen del paciente, del examinador y del procedimiento. Metodología: Estudio prospectivo de una cohorte de 274 pacientes sometidos a mielografía cervical, torácica o lumbar. Se interrogó sobre efectos adversos presentados posterior al procedimiento para análisisuni y bivariado entre quienes presentaron complicaciones y quienes no, con análisis de regresión logística para controlar factores de confusión. Resultados: La incidencia de cefalea es similar a lo observado en Estados Unidos y Europa, siendo menos frecuenteen los extremos de edad. Fueron factores protectores para cefalea el antecedente de punción lumbar y la ausencia de antecedente de cefalea de otra clase. Como factor predisponente se detectó la salida del paciente caminando luego de realizado el procedimiento.Conclusiones: La mayoría de los efectos adversos posterior a la mielografía pueden ser susceptibles de disminuir con el cambio de algunas conductas simples, como es garantizar al paciente completo reposo en decúbito apenas se termine el procedimiento.[Valdivieso OF, Mantilla JC, Moncada JC, Rey JJ.

Search for Anomalous WW/WZ {r_arrow} e{nu}jj Production at D0; Busqueda de Produccion Anomala WW/WZ {r_arrow}e{nu}jj en D-Zero
No full textA search for anomalous WW and WZ production in p{anti p} collisions at {radical}s = 1.8 TeV using the D0 detector at Fermilab is presented. With a data sample of p{anti p} {r_arrow} e{nu}jjX events corresponding to an integrated luminosity of 76.5 {+-} 4.1pb{sup {minus}1}. 399 candidate events were identified, from which 387.1 {+-} 39.8 events were estimated to be background. No deviations from the Standard Model were seen, which predicts 16.2 {+-} 2.7 events. The 95% CL limit on the cross section {sigma}(p{anti p} {r_arrow} W{sup +}W{sup {minus}}X) was calculated to be 93.8 pb. Limits on the CP-conserving anomalous WW{sub {gamma}} and WWZ coupling parameters were obtained from a binned likelihood fit to the transverse momentum spectrum of the W boson. Assuming that the WW{sub {gamma}} and WWZ coupling parameters are equal, the 95% CL limits on the CP-conserving couplings are {minus}0.56 < {Delta}{kappa} < 0.75 (with {lambda} = 0) and {minus}0.42 < {lambda} < 0.44 (with {Delta}{kappa} = 0), for a form factor scale {Lambda}{sub FF} = 1.5 TeV. Limits on other assumptions are also reported. These results were combined with the previous D0 WW, WZ {r_arrow} e{nu}jj published results (13.7 {+-} 0.7 pb{sup {minus}1}), and the limits on the anomalous coupling parameters were set to {minus}0.44 < {Delta}{kappa} < 0.60 (with {lambda} = 0) and {minus}0.34 < {lambda} 0.37 (with {Delta}{kappa} = 0), for a form factor scale {Lambda}{sub FF} = 2.0 TeV
Successful Intubation Using a Cap-Assisted Colonoscope for Endoscopic Retrograde Cholangiopancreatography in Patients Undergoing Roux-en-Y Reconstruction
No full textEndoscopic retrograde cholangiopancreatography (ERCP) is challenging in patients undergoing Roux-en-Y (REY) reconstruction; although balloon-assisted enteroscopy is the first-line treatment, it is not always available considering equipment and expertise. We aimed to evaluate the feasibility of using a cap-assisted colonoscope as the primary approach for ERCP in REY reconstruction. We included 47 patients with REY who underwent ERCP using a cap-assisted colonoscope between January 2017 and February 2022. The primary outcome was intubation success for ERCP using a cap-assisted colonoscope during REY reconstruction. The secondary outcomes were cannulation success, procedure-related adverse events, and variables affecting successful intubation. Comparing side-to-side jejunojejunostomy (SS-JJ) and side-to-end jejunojejunostomy (SE-JJ) groups, the intubation success rate using a cap-assisted colonoscope in the SS-JJ group was higher than that in the SE-JJ group (34 of 38 (89.5%) vs. 1 of 9 (11.1%), p < 0.001). Successful intubation was achieved in 37 (97.4%) and 8 (88.9%) patients in the SS-JJ and SE-JJ groups, respectively, after applying the rescue technique using a balloon-assisted enteroscope for failed ERCP using only a colonoscope. No perforation occurred. Multivariable analysis showed that SS-JJ was a predictive factor for successful intubation (odds ratio [95% confidence interval] = 37.06 [3.91–925.56], p = 0.005). Usage of a cap-assisted colonoscope can be crucial for ERCP in patients undergoing REY reconstruction. Anatomically, SS-JJ can facilitate easy and accurate identification of the afferent limb and a highly successful ERCP using a cap-assisted colonoscope
O comportamento da dengue não é grave nos últimos quatro anos, em Santander, Colômbia
No full textLa transmisión e incidencia del virus del dengue ha aumentado de manera importante en las tres últimas décadas, por lo cual se considera actualmente la enfermedad infecciosa re-emergente que genera mayor morbilidad y mortalidad en el mundo. Objetivo: Observar el comportamiento del dengue no complicado en los últimos cuatro años en Santander, Colombia. MetodologÍa: Se realizó un estudio analÍtico con datos secundarios de dengue no complicado en Santander, entre el año 2007 y el 2015. Se calculó la incidencia por semana epidemiológica y se construyeron canales endémicos de los años 2012 al 2015 mediante logaritmo en base 10, con media geométrica e intervalos de confianza del 95%. La investigación se clasificó como sin riesgo según la Ley 8430 de 1993 de la República de Colombia. Resultados: El Sistema Nacional de Vigilancia en Salud Pública (SIVIGILA) reportó 26,849 casos de dengue no grave en Santander entre el año 2007 y el 2015. Los puntos de corte (éxito, seguridad, riesgo y epidemia) varÍan para las diferentes zonas, con diferencias estadÍsticamente significativas con picos de incidencia de 4.2 (en el 2007), 2.9 (en el año 2010), 8.1 (entre el 2013 y 2014) por cada 100,000 habitantes. Conclusiones: Los canales endémicos de dengue se deben tener en cuenta junto con el impacto de la incidencia calculada para monitoreo de la enfermedad. Según la tendencia secular cada 3 a 4 años se presenta un pico de incidencia, por lo que es probable que en el 2016 se presente un nuevo pico de dengue incluso mayor a los registrados hasta el momento en Santander. Se requieren estrategias medidas e inmediatas para el control de la enfermedad. [Serrano-Gómez SE, De-Montijo C, Rey-Serrano JJ. Comportamiento del dengue no grave en los últimos cuatro años en Santander, Colombia. MedUNAB 2015; 18 (2): 107-115]Transmission and incidence of dengue virus have greatly increased during the last three decades which is the reason why it is currently considered the most emergent infectious disease that causes morbidity and mortality around the world. Objective: Observe simple dengue behavior in the last four years in Santander, Colombia. Method: An analytical study based on secondary data of simple dengue in Santander was performed between the years 2007 and 2015. The weekly epidemiological incidence was calculated and endemic channels between the years of 2012 and 2015 were built using logarithm base 10 with geometric mean and confidence intervals of 95%. The investigation was classified as non-risky according to Law 8430 of 1993, Republic of Colombia. Results: The National Service of Public Health Surveillance (SIVIGILA) reported 26.849 cases of simple dengue in Santander between the years of 2007 and 2015. The cutoff points (success, security, risk, and epidemic) vary in different zones, with significant statistically differences of 4.2 (in 2007), 2.9 (in 2010), and 8.1 (between 2013 and 2014) for each 100.000 inhabitants. Conclusions: The endemic channels of dengue must be taken into account as well as the impact of calculated incidence for monitoring the disease. According to the secular trend, every 3 to 4 years, there is a peak incidence. It is possible that in 2016 a new and bigger peak incidence of dengue will take place in Santander. It is therefore necessary to consider strategies and immediate measures to control this disease. [Serrano-Gómez SE, De-Montijo C, Rey-Serrano JJ.

Evidence for Electroweak Production of W(+/-)W(+/-)jj in pp Collisions at root s=8 TeV with the ATLAS Detector
No full textFurther distribution of this work must maintain attribution to the author(s) and the published article's title, journal citation, and DOI.This Letter presents the first study of W±W±jj, same-electric-charge diboson production in association with two jets, using 20.3 fb-1 of proton-proton collision data at √s=8 TeV recorded by the ATLAS detector at the Large Hadron Collider. Events with two reconstructed same-charge leptons (e±e±, e±μ±, and μ±μ±) and two or more jets are analyzed. Production cross sections are measured in two fiducial regions, with different sensitivities to the electroweak and strong production mechanisms. First evidence for W±W±jj production and electroweak-only W±W±jj production is observed with a significance of 4.5 and 3.6 standard deviations, respectively. The measured production cross sections are in agreement with standard model predictions. Limits at 95% confidence level are set on anomalous quartic gauge couplings
