Upper gastrointestinal (GI) cancers of the stomach and esophagus have high incidence and mortality worldwide, but they are uncommon in Western countries. Little information exists on the association between vitamin D and risk of upper GI cancers. This study examined the association between circulating 25-hydroxyvitamin D (25(OH)D) and upper GI cancer risk in the Cohort Consortium Vitamin D Pool...
Common video representations often deploy an average or maximum pooling of pre-extracted frame features over time. Such an approach provides a simple means to encode feature distributions, but is likely to be suboptimal. As an alternative, we here explore combinations of learnable pooling techniques such as Soft Bag-of-words, Fisher Vectors, NetVLAD, GRU and LSTM to aggregate video features ove...
1. Introduction In the last 15 years, for the standard three-batch stability analyses, debates focused on what is the significance level to be used in the stability pooling tests (pooling intercepts and pooling slopes). Because of the lack of sample size and power consideration, FDA adopted Bancroft's [1] recommendation of using 0.25 as the significant level at any of the pooling tests in order...
OBJECTIVE Annual blood lead (BPb) screening is recommended for children </=2 years of age residing in high-risk areas. Strategies for identifying these areas exist but lack specificity. We sought to develop an efficient method for identifying risk factors for undue lead exposure in children by using community variables. DESIGN Logistic regression for model development in one half of the sampl...
How can di¤erent individualsprobability assignments to some events be aggregated into a collective probability assignment? Classic results on this problem assume that the set of relevant events the agenda is a -algebra and is thus closed under disjunction (union) and conjunction (intersection). We drop this demanding assumption and explore probabilistic opinion pooling on general agendas. On...
We use agent-based modeling to study osotua, a gift giving system used by the Maasai of East Africa. Osotua’s literal meaning is “umbilical cord,” but it is used metaphorically to refer to a specific type of gift-giving relationship. Osotua relationships are characterized by respect, responsibility and restraint. Osotua partners ask each other for help only if they are in need and provide help ...
the credit portfolio management and the optimal credit portfolio selection are identified as one of the most effective factors in banks’ credit risk. two main strategies in this regard include diversification versus concentration. in this study, at first, the status of diversification of iran’s banking sector is analyzed, then the relationship between diversification of the credit portfolio and...
