The monodromy groups of Schwarzian equations on closed Riemann surfaces

Let \theta:\pi_1(R) \to \PSL(2,\C) be a homomorphism of the fundamental group of an oriented, closed surface R of genus exceeding one. We will establish the following theorem. Theorem. Necessary and sufficient for \theta to be the monodromy representation associated with a complex projective stucture on R, either unbranched or with a single branch point of order 2, is that \theta(\pi_1(R)) be nonelementary. A branch point is required if and only if the representation \theta does not lift to \SL(2,\C).Comment: 80 pages, published versio

Análisis de los factores de riesgo para la infección por Klebsiella pneumoniae multirresistente en pacientes postquirúrgicos

En los últimos años, el número de brotes hospitalarios causados por Klebsiella pneumoniae resistente a carbapenems ha aumentado drásticamente. Dichas infecciones están asociadas a una mayor estancia hospitalaria, a un incremento de los costes sociosanitarios y a un aumento de la mortalidad, que en algunos casos es de hasta el 50%. El objetivo principal de nuestro estudio consiste en describir la epidemiología y las características demográficas de los pacientes infectados por Klebsiella pneumoniae resistente a carbapenems en los pacientes intervenidos de cirugía cardíaca con circulación extracorpórea y cirugía abdominal en el Hospital Clínico Universitario de Valladolid. Estudio observacional, retrospectivo de cohortes de pacientes intervenidos de cirugía cardíaca con circulación extracorpórea y cirugía abdominal entre octubre de 2015 y septiembre de 2016, en el Hospital Clínico Universitario de Valladolid, España. Se identificaron 28 casos de Klebsiella pneumoniae resistente a carbapenems. La edad media fue de 68,6 9,73 años, con predominio del sexo masculino (67,9 %). Se pudo observar un claro aumento de la incidencia en pacientes intervenidos de cirugía cardíaca con circulación extracorpórea (82,1%), pacientes con puntuaciones SOFA elevadas (10,32 5,06), ventilación mecánica prolongada (11,7 13,09 días) y reintervenidos (32,1%). La mortalidad registrada fue del 35,7%. La edad fue identificada como factor predictor de mortalidad.Departamento de Cirugía, Oftalmología, Otorrinolaringología y FisioterapiaGrado en Medicin

The neutral acts and the money-laundering offence

La crisis económica ha diezmado las arcas públicas, provocando que se aumenten los esfuerzos para conseguir ingresos. Para ello, se intenta eliminar la existencia de capital no controlado por la Hacienda pública, a través de una legislación cada vez más expansiva. En materia de blanqueo de capitales también se ha vivido esta expansión, quedando incriminadas conductas con una clara vocación delictiva pero también otras que se realizan dentro de los estándares sociales, las conocidas como actos neutrales. Analizaremos la posible subsunción de tales acciones en el tipo del delito de blanqueo de capitales, mediante el estudio del debate doctrinal y jurisprudencial, para fijar los límites de la intervención del derecho penal respecto de las conductas socialmente adecuadasThe economic crisis has decimated the public coffers, producing an increase in efforts to generate revenue. For this reason, eliminating the existence of capital beyond the supervision of the Tax Authority has been attempted through ever-expanding legislation. With regard to money laundering this expansion has also been imposed, criminalising not only conduct of a clear criminal vocation but also that which falls within social standards: the so-called neutral acts. We will analyse the possible subsumption of such actions in the money laundering offense by examining jurisprudence and case law, in order to establish the limits of the intervention of criminal law with respect to socially appropriate conduc

Attractive regular stochastic chains: perfect simulation and phase transition

We prove that uniqueness of the stationary chain, or equivalently, of the $g$-measure, compatible with an attractive regular probability kernel is equivalent to either one of the following two assertions for this chain: (1) it is a finitary coding of an i.i.d. process with countable alphabet, (2) the concentration of measure holds at exponential rate. We show in particular that if a stationary chain is uniquely defined by a kernel that is continuous and attractive, then this chain can be sampled using a coupling-from-the-past algorithm. For the original Bramson-Kalikow model we further prove that there exists a unique compatible chain if and only if the chain is a finitary coding of a finite alphabet i.i.d. process. Finally, we obtain some partial results on conditions for phase transition for general chains of infinite order.Comment: 22 pages, 1 pseudo-algorithm, 1 figure. Minor changes in the presentation.

Vaccinia virus binds to the scavenger receptor MARCO on the surface of keratinocytes.

Patients with altered skin immunity, such as individuals with atopic dermatitis (AD), can have a life-threatening disruption of the epidermis known as eczema vaccinatum after vaccinia virus (VV) infection of the skin. Here, we sought to better understand the mechanism(s) by which VV associates with keratinocytes. The class A scavenger receptor known as MARCO (macrophage receptor with collagenous structure) is expressed on human and mouse keratinocytes and found to be abundantly expressed in the skin of patients with AD. VV bound directly to MARCO, and overexpression of MARCO increased susceptibility to VV infection. Furthermore, ligands with affinity for MARCO, or excess soluble MARCO, competitively inhibited VV infection. These findings indicate that MARCO promotes VV infection and highlights potential new therapeutic strategies for prevention of VV infection in the skin

Telemedicine platforms must be leveraged to strengthen rural health systems

[Extract] Telemedicine is a technology that has come of age, now it must be put to use to address inequities in cancer care. The principles and applications of telemedicine have undergone rapid evolution over the last two years globally.1, 2 Prior to the COVID-19 pandemic, the utilisation of telemedicine was largely driven by local champions and lacked systematic uptake despite Government investment and incentives at both state and commonwealth levels. The pandemic and the resulting need for social distancing saw rapid and widespread adoption of telephone and telehealth services aided by Government funding, even for patients in metropolitan areas. Now is the time to leverage this momentum to embed telemedicine in our health systems
