A Bayesian Point Process Model for User Return Time Prediction in Recommendation Systems

In order to sustain the user-base for a web service, it is important to know the return time of a user to the service. In this work, we propose a point process model which captures the temporal dynamics of the user activities associated with a web service. The time at which the user returns to the service is predicted, given a set of historical data. We propose to use a Bayesian non-parametric model, log Gaussian Cox process (LGCP), which allows the latent intensity function generating the return times to be learnt non-parametrically from the data. It also allows us to encode prior domain knowledge such as periodicity in users return time using Gaussian process kernels. Further, we cap- ture the similarities among the users in their return time by using a multi-task learning approach in the LGCP framework. We compare the performance of LGCP with different kernels on a real- world last.fm data and show their superior performance over standard radial basis function kernel and baseline models. We also found LGCP with multitask learning kernel to provide an improved predictive performance by capturing the user similarity

We show the effectiveness of the proposed approaches on predicting the return time of users to last.fm music service

Effect of hydration therapy on oligohydramnios

Background: Oligamnios is defined as an AFI 34 weeks with AFI <5 cms were randomised into an Intervention group who receive 1 litre of ringer lactate i.v given daily for 5 days and nonintervention group who were kept under observation by serial ultrasound and antepartum fetal surveillance. All were followed-up till delivery to obtain maternal and perinatal outcomes.Results: Among the 68 who were given intervention, 61 responded and 7 were non responders. With hydration therapy, mean increase in AFI was 4 cm and minimum duration needed for improvement was one week. Hydration therapy showed significant improvement in the maternal and fetal outcomes. Intravenous route of maternal hydration has the advantage that a fixed amount of fluid can be infused at a relatively constant rate with ensured compliance.Conclusions: From the study, it was concluded that Hydration therapy is an excellent method to improve AFI in Oligohydramnios and maternal and perinatal outcome

Impacts of Short-term Exposure of Caselio (plant fertilizer) On The Freshwater Snail, Lanistes carinatus (Ampullariidae, Mollusca)

ABSTRACT Ecotoxicological effects of agriculture products especially fertilizers on aquatic invertebrates is a crucial case to study. The effect of Caselio, the fertilizer (Plant Metabolism Regulators, PMR) on aquatic organisms&apos; response is of great importance. The freshwater snail, Lanistes carinatus was collected from Bahr Shebeen canal, Menoufia Province, Egypt. Snails were exposed to 200 and 600 µl/l of the plant fertilizer (PMR) for 0, 1, 3 and 7 days. Endpoints investigated were LC 50 , 90 , condition index (CI), shell, operculum, foot and soft tissue metals concentrations (Zn, Fe, Mn and Ca), metallothioneins (MTs) and antioxidants (Catalase; CAT and Total Glutathione; GSH) of gonad-digestive complex. LC 50 and LC 90 values were 1.3 and 4.2 ml/l, respectively. CI of the exposed snails reduced significantly especially on the 1 st day (17.5 % reduction). The plant fertilizer (PMR) exposure caused metal accumulation mainly in digestive-gonad complex, followed by the shell, foot and lastly the operculum. Exposure to the plant fertilizer (PMR) resulted in lower Ca concentrations in shell, but disturbed/increased its content in the rest tissues of the exposed snails (ANOVA/Kruskal Wallis, P ≤ 0.05). Metallothioneins increased 1.5 fold in the plant fertilizer (PMR) exposed snails` digestive-gonad complex (200 and 600 µl/l) when compared to the control group (3223.2 ± 127.5, 2797.6 ± 119.4 and 2076.4 ± 73.8 pg/mg, respectively). The plant fertilizer (PMR) caused increase in the activity of the antioxidants CAT but decrease in GSH concentration significantly (Kruskal Wallis, P ≤ 0.05) in the digestive-gonad complex of the exposed snails. It can be conclude that the plant fertilizer (PMR) exposure affected the biological responses in L. carinatus with specific tissue response and caused oxidative stress. Digestive-gonad complex, foot and shell could be used as target organs and biomarkers for metals accumulation; however, operculum was not a target organ for metal accumulation

Bacteriological and Molecular Identification of Thermophilic Campylobacters of Animal and Human Origins in Beni-Suef Governorate, Egypt

Thermophilic species of the genus Campylobacter are generally considered commensals of livestock and the leading cause of bacterial food-borne zoonoses. The present study was delineated to clarify the role of Campylobacter species as a diarrheagenic pathogen in animals and man and to investigate the fecal carriage rate of Campylobacters in animals and in-contact humans. A total number of 78 fecal samples were collected from diarrheic and non-diarrheic cattle (n=26), sheep (n=28) and humans (n=24). Samples were enriched in Preston broth, followed by streaking on selective Campylobacter agar base medium. The suspected colonies were tested morphologically and biochemically. Campylobacter spp. was recovered from 29 (37.17%) out of 78 fecal samples (34.61%, 42.85% and 33.33%) for cattle, sheep and humans, respectively. Positive correlation between the occurrence of diarrhea and the isolation of Campylobacters was observed in samples of human origin while in adult ruminants particularly sheep, high fecal carriage rate was observed in non-diarrheic animals. The isolates were identified to genus and species levels by polymerase chain reaction targeting the 16S rRNA gene, the mapA gene and the ceuE gene which revealed that all of isolates were Campylobacter jejuni. These findings pose a significant epidemiological implication where cattle and sheep act as vehicles of, and excrete Campylobacter jejuni which is capable of causing disease in the local community in the area of investigation

A classic triphasic pleomorphic adenoma of nasal cavity mimicking as malignancy: a rare case report

Pleomorphic adenoma (PA) is the most common benign tumor of major salivary glands and intra nasal PA is unusual which may be misdiagnosed as malignancy. A 65-year-old female presented with unilateral nasal bleeding and nasal obstruction in right nasal cavity for 6 months. Local examination showed polypoid mass which surgically excised. HPE showed classic triphasic component of epithelial, myoepithelial with cartilaginous stromal elements and pathological diagnosis of PA made. High cellularity of tumor and predominant squamous epithelial component with keratin pearl created diagnostic confusion of malignancy and it confirmed by immune-histochemistry using p63 to demonstrate presence of myoepithelial component. Highlighted this case report for its unusual location and rare triphasic component of tumor tissue with keratin pearl formation which mimic as malignancy

Extensibility of External Magnetic Potential at High Latitudes - Antarctica

We investigated the external magnetic potential due to solar forcing, with nine years of data during 2001-2009, coveringthe deep solar minimum (2006-2009), at two stations: one is in the polar cap -Vostok (78º27'S, 106º52’E; mag. lat 83oS) andanother is in the subauroral region - Maitri (70º45'S, 11º43'E: mag. lat 67oS) in Antarctica. The significance of the work isassociated with space weather prediction and its impact on planet Earth. We used Advance Composition Explorer (ACE)satellite data for the aforesaid period for a thorough understanding of influences due to solar wind origin and to compare theparameter observed in these regions. We used the spherical cap harmonic analysis (SCHA) function as a tool. The inferenceindicates that at Vostok the magnitude is enhanced throughout and depicts a broad ambient external magnetic potential. Itseems to be essentially the intensification of the region 1 currents whereas at Maitri intense electric fields are producedduring geomagnetic perturbations which drive a system of disturbed time Region 2 currents over the quiet time currents.During this scenario in Maitri there are noticeable peaks or enhancements in the magnetic potential that can be observedmainly during geomagnetic disturbances. Hence the regression relation developed for external magnetic potentialcalculation, in terms of solar wind parameters agrees well with polar cap region and the area is relatively less exploredearlier, the present investigation can be expected to add knowledge about that regime
