The Higgs Sector and electron electric dipole moment in next-to-minimal supersymmetry with explicit CP violation

We study the explicit CP violation of the Higgs sector in the next--to--minimal supersymmetric model with a gauge singlet Higgs field. Our numerical predictions show that electric dipole moment of electron lies around the present experimental upper limits. The mass of the lightest Higgs boson is quite sensitive to the CP violating phases in the theory. It is observed that as the vacuum expectation value of the singlet gets higher values, CP violation increases.Comment: 20 pages, 16 figure

Emerging Market Business Cycles Revisited: Learning about the Trend

We build an equilibrium business cycle model in which agents cannot perfectly distinguish between the permanent and transitory components of TFP shocks and learn about those components using the Kalman filter. Calibrated to Mexico, the model predicts a higher variability of consumption relative to output and a strongly negative correlation between the trade balance and output for a wide range of variability and persistence of permanent shocks vis-a-vis the transitory shocks. Moreover, our estimation for Mexico and Canada suggests more severe informational frictions in emerging markets than in developed economies.emerging markets, business cycles, learning, Kalman filter

Dominant currency paradigm†

We propose a “dominant currency paradigm” with three key features: dominant currency pricing, pricing complementarities, and imported inputs in production. We test this paradigm using a new dataset of bilateral price and volume indices for more than 2,500 country pairs that covers 91 percent of world trade, as well as detailed firm-product-country data for Colombian exports and imports. In strong support of the paradigm we find that (i) noncommodities terms-of-trade are uncorrelated with exchange rates; (ii) the dollar exchange rate quantitatively dominates the bilateral exchange rate in price pass-through and trade elasticity regressions, and this effect is increasing in the share of imports invoiced in dollars; (iii) US import volumes are significantly less sensitive to bilateral exchange rates, compared to other countries’ imports; (iv) a 1 percent US dollar appreciation against all other currencies predicts a 0.6 percent decline within a year in the volume of total trade between countries in the rest of the world, controlling for the global business cycle. We characterize the transmission of, and spillovers from, monetary policy shocks in this environment

Muerte de un lince ibérico. Establecimiento de la causa y la autoría

Las ciencias forenses se aplican desde hace poco tiempo como herramientas en las investigaciones de delitos contra el medio ambiente. En este trabajo se expone un caso pionero en cuanto a la utilización de estas técnicas en un caso de un delit o contra la fauna silvestre. La investigación se inicia tras la apari ción de un lince ibérico muerto en el interior de una finca, donde se encontraron también varios pollos supuestamente utilizados como cebos envenenados y otro cadáver, el de un zorro. El lince ib érico es uno de los mamíferos más amenazados del planeta. Se llevaron a cabo distintos análisis a partir de la necropsia de los cadáveres en el Centro de Análisis y Diagnóstico de la Fauna Silvestre (CAD), el laboratorio de referencia para la fauna silvestre pertene ciente a la Junta de Andalucía. Los resultados fuer on concluyentes, ambas muertes se produjeron como consecuencia de la ingestión de cebos envenenados con un plaguicida extremadamente tóxico, el aldicarb. También se encontró esta sustancia en los pollos recogidos en el interior de la finca. Con el fin de e stablecer la culpabilidad de los propietarios de la finca, que negaron tener nada que ver con las muertes y la colocación de los cebos, se utilizó una herramienta novedosa en este tipo de investigaciones, la genética forens e. En base a los resultados se co nsiguió establecer una relación de parentesco entre los pollos utilizados como cebos envenenados y los pollos propiedad reconocida de los sospechosos, que permitió demostrar que todos tenían el mismo origen. Gracias al trabajo conjunto y coordinado durante toda la investigación y el informe pericial elaborado por el laboratorio del CAD, la Consejería de Medio Ambiente y Organización del Territorio de la Junta de Andalucía consiguió una sentencia ejemplar contra los envenenador es.The application of forensic science as a research tool to resolve crimes against the environment is relatively rec ent. To our knowledge this is the first instance in which the forensic genetic have been used as a definitive evidence to find out guilty in crimes against the wildlife. Our research starts when an Iberian lynx was found dead into a farm; very close to sev eral chickens used as poisoned baits and a fox carcass. Iberian lynx is one of the most endangered mammals in the planet. A comprehensive investigation from the carcasses was performed in the Analysis and Diagnostic Center for Wildlife in Andalucia (CAD), the reference laboratory for wildlife of the Andalusian Government (Spain). The results determined that the deaths occurred as a result of ingestion o f baits poisoned with an extremely toxic pesticide, aldicarb. This substance was also found in chickens ga thered inside the farm. In order to establish the guilt of the owners of the farm, who refused to be related to the deaths and the placement of the b aits, an innovative tool was used in this kind of research, the forensic genetic. Based on the results we got, we established a relationship between the chickens used as poisoned baits and the chickens from the farmer, all of them had the same origin. Thanks to the coordinated actuation during the complete investigation and the official report by the CAD labor atory used in the trial, the Ministry of Environmental and Territorial Organization got an exemplary sentence against the poisoners

Clinical and Demographic Characteristics and Two-Year Efficacy and Safety Data of 508 Multiple Sclerosis Patients with Fingolimod Treatment

Introduction: Fingolimod is the first oral immunomodulatory treatment used as secondary care therapy in the treatment of multiple sclerosis for the last 10 years. The objective of our study is to reveal the experiences of the first generic fingolimod active ingredient treatment in different centers across Turkey. Method: The first generic fingolimod efficacy and safety data of patients followed-up in 29 different clinical multiple sclerosis units in Turkey were analyzed retrospectively. Data regarding efficacy and safety of the patients were transferred to the data system both before the treatment and on the 6th, 12th and 24th month following the treatment. The data were analyzed using the IBM SPSS 20.00. P value of <0.05 was considered to be statistically significant. Results: A total of 508 multiple sclerosis patients, 331 of whom were women, were included in the study. Upon comparing the Expanded Disability Status values before and after the treatment, a significant decrease was observed, especially at month 6 and thereafter. Since bradycardia occurred in 11 of the patients (2.3%), the first dose had to be longer than 6 hours. During the observation of the first dose, no issues that could prevent the use of the drug occured. Side effects were seen in 49 (10.3%) patients during the course of fingolimod treatment. Respectively, the most frequent side effects were bradycardia, hypotension, headache, dizziness and tachycardia. Conclusion: The observed results regarding efficacy and safety were similar to clinical trial data in the literature and real life data in terms of the first equivalent with fingolimod active ingredient. © 2023, Turkish Neuropsychiatric Society.

Classical limit for the scattering of Dirac particles in a magnetic field

We present a relativistic quantum calculation at first order in perturbation theory of the differential cross section for a Dirac particle scattered by a solenoidal magnetic field. The resulting cross section is symmetric in the scattering angle as those obtained by Aharonov and Bohm (AB) in the string limit and by Landau and Lifshitz (LL) for the non relativistic case. We show that taking pr_0\|sin(\theta/2)|/\hbar<<1 in our expression of the differential cross section it reduces to the one reported by AB, and if additionally we assume \theta << 1 our result becomes the one obtained by LL. However, these limits are explicitly singular in \hbar as opposed to our initial result. We analyze the singular behavior in \hbar and show that the perturbative Planck's limit (\hbar -> 0) is consistent, contrarily to those of the AB and LL expressions. We also discuss the scattering in a uniform and constant magnetic field, which resembles some features of QCD

Structural and Electrostatic Characterization of Pariacoto Virus: Implications for Viral Asembly

This is the peer reviewed version of the following article:Devkota, B., Petrov, A., Lemieux, S., Boz, M. B., Tang, L., Schneemann, A., … Harvey, S. C. (2009). Structural and Electrostatic Characterization of Pariacoto Virus: Implications for Viral Asembly. Biopolymers, 91(7), 530–538. http://doi.org/10.1002/bip.21168, which has been published in final form at doi.org/10.1002/bip.21168. This article may be used for non-commercial purposes in accordance with Wiley Terms and Conditions for Self-ArchivingWe present the first all-atom model for the structure of a T=3 virus, pariacoto virus (PaV), which is a non-enveloped, icosahedral RNA virus and a member of the Nodaviridae family. The model is an extension of the crystal structure, which reveals about 88% of the protein structure but only about 35% of the RNA structure. Evaluation of alternative models confirms our earlier observation that the polycationic protein tails must penetrate deeply into the core of the virus, where they stabilize the structure by neutralizing a substantial fraction of the RNA charge. This leads us to propose a model for the assembly of small icosahedral RNA viruses: nonspecific binding of the protein tails to the RNA leads to a collapse of the complex, in a fashion reminiscent of DNA condensation. The globular protein domains are excluded from the condensed phase but are tethered to it, so they accumulate in a shell around the condensed phase, where their concentration is high enough to trigger oligomerization and formation of the mature virus

CP-odd invariants in models with several Higgs doublets

We present CP-odd Higgs-basis invariants, which can be used to signal CP violation in a multi-Higgs system, written in an arbitrary Higgs basis. It is shown through specific examples how these CP-odd invariants can also be useful to determine the character of CP breaking (i.e. whether it is hard or soft CP breaking) in a given Higgs Lagrangian. We analyse in detail the cases of two and three Higgs doublets
