Inclusive and diffractive dijet photoproduction in UPCs at the LHC in NLO QCD
2019
We present a next-to-leading order QCD calculation of inclusive dijet photoproduction in ultraperipheral Pb-Pb collisions at the LHC and show that the results agree very well with various kinematic distributions measured by the ATLAS collaboration. The effect of including these data in nCTEQ or EPPS16 nuclear parton density functions (nPDFs) is then studied using the Bayesian reweighting technique. For an assumed total error of 5\% on the final data, its inclusion would lead to a significant reduction of the nPDF uncertainties of up to a factor of two at small values of the parton momentum fraction. As an outlook, we discuss future analyes of diffractive nPDFs, which are so far completely u…
Fitting particle size distribution models to data from Burundian soils for the BEST procedure and other purposes
2009
Testing the Beerkan Estimation of Soil Transfer (BEST) soil particle size distribution (PSD) model is necessary to evaluate the applicability of the BEST procedure for characterising soil hydraulics. In this investigation, the fitting performance of the BEST PSD model was tested using a database of 114 Burundian soils with 14 measured particle size fractions for each soil sample, and also by considering a reduced number of measured particle size fractions for a sample. The fitting performance of the model developed by Fredlund et al. (2000) (FR model) was also considered for comparative purposes. On average, the BEST model yielded satisfactory results (i.e., mean relative error, E r ¯ = 3.9…
Intraepidermal morphologic manifestations in lysosomal diseases.
1989
This paper reports the ultrastructural findings for the epidermis of biopsied skin specimens in numerous lysosomal diseases, which can be grouped as follows: a) presence of vacuolar lysosomal residual bodies in mucopolysaccharidoses I, II and III, Salla disease, GM 2 -gangliosidoses and infantile type II glycogenosis; b) avacuolar lysosomal residual bodies in Niemann-Pick disease type C, mucolipidosis IV, Farber disease, Fabry disease, and late infantile and juvenile neuronal ceroid-lipofuscinoses; c) absence of lysosomal residual bodies in GM 2 -gangliosidoses, metachromatic leukodystrophy, Gaucher disease and sialidosis type III Whenever possible, a biopsy of the skin for morphological di…
Population Level Survival of Patients with Chronic Myeloid Leukemia in Germany in the Early 21st Century
2012
Abstract Abstract 759 Background: Chronic myeloid leukemia (CML) is a rare but highly treatable form of leukemia. Recent advances in the treatment of CML have dramatically improved survival in clinical trials. Prior work using the Surveillance, Epidemiology, and End Results (SEER) database in the United States (US) suggest that survival on the population level has increased, but still lags behind that seen in clinical trials1. In the past, evaluation of population level survival in other countries has been hampered by the lack of high quality data from a large enough population to evaluate trends in survival in this rare disease. Recently, a collaborative effort between the German Cancer Re…
VALIDACIÓN DE UNA ESCALA PARA EL ANÁLISIS DE LAS PERCEPCIONES DE LOS RESIDENTES SOBRE EL IMPACTO SOCIAL DE UN CENTRO DEPORTIVO
2019
Resumen La finalidad de este estudio es validar una escala para el análisis de las percepciones de los residentes sobre el impacto social de un centro deportivo. Se recogió una muestra de 406 residentes del municipio de Moncada (Valencia), con un error de muestreo de ±4,82, que contestaron a una encuesta de 31 ítems que recogían posibles impactos sociales derivados de la presencia del centro deportivo en la localidad. La aplicación de análisis factorial exploratorio y confirmatorio redujo la escala a 28 indicadores distribuidos en siete dimensiones de impacto: impacto sociocultural, impacto socioeconómico, impacto en la imagen y la promoción del municipio, impacto en el desarrollo urbano y …
Multi-system machine translation using online APIs for English-Latvian
2015
This paper describes a hybrid machine translation (HMT) system that employs several online MT system application program interfaces (APIs) forming a MultiSystem Machine Translation (MSMT) approach. The goal is to improve the automated translation of English – Latvian texts over each of the individual MT APIs. The selection of the best hypothesis translation is done by calculating the perplexity for each hypothesis. Experiment results show a slight improvement of BLEU score and WER (word error rate).
Posterior chamber phakic intraocular lenses to improve visual outcomes in keratoconus patients
2016
The aim of this review is to summarize the results of using posterior chamber phakic intraocular lenses (pIOLs) to restore quality of vision in keratoconus patients. These pIOLs can correct the refractive errors associated with keratoconus and can also be combined with other surgical techniques to improve the results.
Two-stage adaptive designs with correlated test statistics.
2005
When performing a trial using an adaptive sequential design, it is usually assumed that the data for each stage come from different units; for example, patients. However, sometimes it is not possible to satisfy this condition or to check whether it is satisfied. In these cases, the test statistics and p-values of each stage may be dependent. In this paper we investigate the type I error of two-stage adaptive designs when the test statistics from the stages are assumed to be bivariate normal. Analytical considerations are performed under the restriction that the conditional error function is constant in the continuation region. We show that the decisions can become conservative as well as an…
Ultrafast Fault-Tolerant Long-Distance Quantum Communication with Static Linear Optics
2017
We present an in-depth analysis regarding the error resistance and optimization of our all-optical Bell measurement and ultrafast long-distance quantum communication scheme proposed in [arXiv:1503.06777]. In order to promote our previous proposal from loss- to fault-tolerance, we introduce a general and compact formalism that can also be applied to other related schemes (including non-all-optical ones such as [PRL 112, 250501]). With the help of this new representation we show that our communication protocol does not only counteract the inevitable photon loss during channel transmission, but is also able to resist common experimental errors such as Pauli-type errors (bit- and phase-flips) a…
Syntax Error Handling
1990
In the previous chapters we have seen that the various parsers discussed, at least whenever they are deterministic, detect an error in any nonsentence. This means, that on any nonsentence there is a computation ending with an error configuration. For practical parsers, mere error detection is not enough; the parser should also emit a meaningful error message and recover from the error. A recovery means that the error configuration is transformed into a non-error configuration at which normal parsing can be resumed. Moreover, the transformation should be done so that as few input symbols as possible will be discarded. The goal of the error recovery is to maximize the amount of input text tha…
