BI-RADS-3 is a category in mammography for probably benign lesions and for which periodic follow-up with repeat imaging is recommended. At our institution repeated mammograms are performed at 6, 12, 18, and 24 months. The purpose of this study was to assess the significance of 18-month mammogram for evaluation of BI-RADS-3 lesions. Following IRB ap...
How to model user interests and intentions through user profiling is an important key for providing personalized service on Internet. User profiling can be seen as the inference of user interests, intentions, characteristics, behaviors and preferences. This paper introduces a scalable and automated technique for user profiling by extracting his URL...
User profiling, defined as the inference of user interests, intentions, characteristics, behaviors and preferences, is nowadays one of the most important keys in personalized services on Internet, such as segmented target advertisements. In this paper, we propose a scalable and automated technique for user ontology profiling in social networks by e...
PURPOSE
To assess the influence of inter-reader variability of radiologists interpreting mammograms during the course of a two-year BI-RADS 3 follow up protocol.
METHOD AND MATERIALS
In this IRB approved retrospective study, medical records from February 1, 2002 to May 31, 2009 were reviewed, using a dedicated mammography database and the electron...
Resumen
Se presentan los resultados de un estudio sobre la influencia del gesto icónico en la memoria de trabajo en estudiantes con discapacidad intelectual leve. Cómo hipótesis general se planteó que la retención de la información verbal en la memoria de trabajo variaría en función del uso de gestos en niños/as con discapacidad intelectual leve, d...
Few studies have been done in Cuba for determining the thrips present on crops of the family Aliaceae. The major researches have been carried out on Thrips tabaci Lindenman, which is considered the major pest on these crops. For detecting the presence of thrips on this group of plants, three botanical species, onion, garlic and chive, were sampled...
This paper shows that breaking the barrier of 1 triangle/clock rasterization rate for microtriangles in modern GPU architectures
in an efficient way is possible. The fixed throughput of the special purpose culling and triangle setup stages of the classic
pipeline limits the GPU scalability to rasterize many triangles in parallel when these cover ve...
Los trips se caracterizan por constituir plagas en múltiples cultivos, causando daños directos a través de la alimentación o por la diseminación de enfermedades virales a diferentes cultivos, entre los que se encuentran las hortalizas (Prasada et al. 2003). En Cuba han sido escasos los estudios dirigidos a determinar la presencia de las diferentes...
Las plantas arvenses constituyen reservorios importantes para los trips, desde donde parten para infestar los diversos cultivos de importancia económica. Para conocer los tisanópteros presentes en las mismas se muestrearon 20 especies botánicas, pertenecientes a 13 familias, en nueve municipios de la provincia La Habana durante los años 2003 y 2004...
In reviewing the literature the dramatic role that memory and language have played in studies of cognitive processes is noticeable. However, there are few studies of the influence of non-verbal language -and specifically of gestures- on the working memory. This paper reviews the theory of how gestures facilitate working memory tasks both in childre...
The rapid pace of change in 3D game technology makes workload characterization necessary for every game generation. Comparing to CPU characterization, far less quantitative information about games is available. This paper focuses on analyzing a set of modern 3D games at the API call level and at the micro architectural level using the Attila simula...
Con el objetivo de obtener información epidemiológica de rebaños bovinos de raza Carora y mestizajes de Cebuínos con Pardo Suizo y Holstein infestados en condiciones naturales y estratificados en cuatro grupos etarios, mediante el empleo de antihelmínticos sobre la prevalencia y las cargas parasitarias expresadas en número de huevos de estróngilos...
The present work presents a cycle-level execution-driven simulator for modern GPU architectures. We discuss the sim- ulation model used for our GPU simulator, based in the con- cept of boxes and signals, and the relation between the timing simulator and the functional emulator. The simulation model we use helps to increase the accuracy and reduce t...
The aim of the present study was to gather epidemiological data in bovine herds of the Carora breed and crossings of Brahman, Holstein and Brown Swiss naturally infected. Animals were set out in four age groups to obtain information about management and anthelmintic control on prevalence and parasitic burdens expressed in eggs per feces gram number...
We present the TILA-rin GPU microarchitecture for embedded systems. We evaluate the architecture using the ATTILA GPU simulation framework. We use a trace from an execution of the Unreal Tournament 2004 PC game to evaluate and compare the performance of the proposed GPU and a baseline GPU architecture for the PC. This work presents the dif- ferent...
In spite of recent developments focusing on milling process
optimization through an effective cutting force control, there is a need
for the analysis of the transient response of these systems because
undesirable oscillations in cutting force can be harmful to the quality
of the finishing surface and tools. The main goal of this work is to
develop...
The difficulties in implementing adaptive and other advanced
control schemes in industrial machining processes have encouraged
researchers to combine the utilization of one hierarchical level, a
fuzzy control algorithm, and robust sensing systems. The main idea of
this paper deals with self-regulating controllers (SRCs). The control
signal's scalin...
The humoral response to Salmonella typhi is important for protective immunity against typhoid fever, as indicated by the protection obtained with killed cell vaccines and component vaccines (outer membrane proteins, Vi antigen) in animals and human beings. Nonetheless, analysis and interpretation of host humoral immune response to S. typhi surface...
Typhoid is a febrile and bacteremic disease of intestinal origin characterized by low but persistent numbers of Salmonella typhi in the blood stream (Christie, 1987). The defervescence of the febrile disease in untreated typhoid coincides with the appearance of cell-mediated immunity, as manifested by the delayed type hypersensitivity phenomena of...
