Although most decision research concerns choice between simultaneously presented options, in many situations options are encountered serially, and the decision is whether to exploit an option or search for a better one. Such problems have a rich history in animal foraging, but we know little about the psychological processes involved. In particular, it is unknown whether learning in these probl...

We describe a new vaccination method called modified vaccination technique (MVT). The technique is able to achieve downregulation of pathogenic autoimmune events leading to a chronic progressive disorder in rats called slowly progressive Heymann nephritis. Downregulation of immunopathological events is achieved by injections of immune complex (IC) made up of the target native antigen (ag) and s...

In spite of enormous efforts there have been no solutions to date for preventing/ terminating chronic disorders of humans by vaccination or drugs. Yet it is well understood that if the target antigen (ag) could be presented appropriately to the cells of the immune system then solutions could be found. Recently, the Barabas research group has introduced and described the third vaccination method...

Foraging theory provides archaeology with a valuable set of tools for investigating the constraints that influenced procurement decisions of the past. The prey-choice model has been used extensively by archaeologists, but has significant limitations given the nature of archaeological data. This paper suggests that the seldom-used Marginal Value Theorem (MVT) is a valuable tool for examining the...

Objectives: To report the success of treatment with lowmolecular-weight heparins (LMWHs) in a case of nephrotic syndrome complicated by mesenteric vein thrombosis (MVT) and portal vein thrombosis (PVT). Clinical Presentation and Intervention: A 53-year-old man with nephrotic syndrome developed persistent mild abdominal pain for 3 days. Hepatic-portal venous system thrombosis of nephrotic syndro...

In hybrid foraging, observers search for multiple instances of target types. Children regularly perform such tasks (e.g., collecting LEGO pieces or looking different teammates within a game). Quitting rules (When do you leave the search?) are important in foraging I found enough LEGOs teammates). However, development quitting behavior has not yet been experimentally studied, and it could give u...

We present a new method for assignment of devices with different Vth in a double-Vth-process, whereas leakage is reduced and performance increases or is constant. A mixed-Vth gate type is developed, which renders new masks unnecessary. As compared with known methods, our approach achieves an additional leakage reduction of 25% while leakage reduction in raw designs is average 65%.

Superior mesenteric vein thrombosis (SMVT) is a rare yet frequently fatal cause of intestinal ischemia. Despite its severe consequences, SMVT often presents with nonspecific symptoms such as nausea, vomiting, and abdominal pain. It can occur with or without gastrointestinal bleeding, and symptoms may be present for hours to weeks. Physical exam can vary from a benign to an acute abdomen. The ar...
