Learning Monocular 3D Human Pose Estimation from Multi-view Images
Accurate 3D human pose estimation from single images is possible with
sophisticated deep-net architectures that have been trained on very large
datasets. However, this still leaves open the problem of capturing motions for
which no such database exists. Manual annotation is tedious, slow, and
error-prone. In this paper, we propose to replace most of the annotations by
the use of multiple views, at training time only. Specifically, we train the
system to predict the same pose in all views. Such a consistency constraint is
necessary but not sufficient to predict accurate poses. We therefore complement
it with a supervised loss aiming to predict the correct pose in a small set of
labeled images, and with a regularization term that penalizes drift from
initial predictions. Furthermore, we propose a method to estimate camera pose
jointly with human pose, which lets us utilize multi-view footage where
calibration is difficult, e.g., for pan-tilt or moving handheld cameras. We
demonstrate the effectiveness of our approach on established benchmarks, as
well as on a new Ski dataset with rotating cameras and expert ski motion, for
which annotations are truly hard to obtain.Comment: CVPR 2018, Ski-Pose PTZ-Camera Dataset availabl
In vitro isolation of equine piroplasms derived from Cape Mountain zebra (Equus zebra zebra) in South Africa
Twenty blood samples of zebras ( Equus zebra zebra) from the Karoo National Park and the Bontebok National Park in South Africa, all seropositive for Theileria equi, were subjected to in vitro culture to identify carrier animals and to isolate the parasites. Sixteen animals had a detectable parasitaemia in Giemsa-stained blood smears examined before culture initiation, the remaining four animals were identified as T. equi carriers by in vitro culture. Cultures were initiated either in an oxygen-reduced gas mixture or in a 5% CO2-in-air atmosphere. Out of the 20 blood samples, 12 cultures of T. equi and two cultures of T. equi mixed with Babesia caballi were established. None of the four animals seropositive for B. caballi could be identified as carrier animals, whereas two seronegative samples became culture-positive for B. caballiThe articles have been scanned in colour with a HP Scanjet 5590; 600dpi.

CLIB-Graduate Cluster Industrial Biotechnology: Ein neuer Weg zur praxisnahen Doktorandenausbildung
Estrategias cognitivas para la comprensión lectora de textos narrativos en estudiantes de segundo grado de educación básica primaria en una institución educativa de la ciudad de Barranquilla
La lectura es sin caer en la exageración, una de las actividades humanas más enriquecedoras y productivas para los individuos, dado que leer y comprender lo que se lee, sella el futuro profesional e intelectual del lector. Con este trabajo de investigación, se pretende fortalecer la comprensión lectora de textos narrativos en estudiantes de segundo grado, a través de la aplicación de estrategias cognitivas, tales como identificación del tema principal, subrayado y paráfrasis, con la finalidad que éstas se adapten como estrategia curricular en el plantel educativo donde se desarrolló el trabajo de investigación y con ello se mejore la competencia de comprensión lectora en toda la institución

A Cross-Sectional Study of People with Epilepsy and Neurocysticercosis in Tanzania: Clinical Characteristics and Diagnostic Approaches.
Neurocysticercosis (NCC) is a major cause of epilepsy in regions where pigs are free-ranging and hygiene is poor. Pork production is expected to increase in the next decade in sub-Saharan Africa, hence NCC will likely become more prevalent. In this study, people with epilepsy (PWE, n=212) were followed up 28.6 months after diagnosis of epilepsy. CT scans were performed, and serum and cerebrospinal fluid (CSF) of selected PWE were analysed. We compared the demographic data, clinical characteristics, and associated risk factors of PWE with and without NCC. PWE with NCC (n=35) were more likely to be older at first seizure (24.3 vs. 16.3 years, p=0.097), consumed more pork (97.1% vs. 73.6%, p=0.001), and were more often a member of the Iraqw tribe (94.3% vs. 67.8%, p=0.005) than PWE without NCC (n=177). PWE and NCC who were compliant with anti-epileptic medications had a significantly higher reduction of seizures (98.6% vs. 89.2%, p=0.046). Other characteristics such as gender, seizure frequency, compliance, past medical history, close contact with pigs, use of latrines and family history of seizures did not differ significantly between the two groups. The number of NCC lesions and active NCC lesions were significantly associated with a positive antibody result. The electroimmunotransfer blot, developed by the Centers for Disease Control and Prevention, was more sensitive than a commercial western blot, especially in PWE and cerebral calcifications. This is the first study to systematically compare the clinical characteristics of PWE due to NCC or other causes and to explore the utility of two different antibody tests for diagnosis of NCC in sub-Saharan Africa
