Intensive food sharing among foragers and horticulturists is commonly explained as a means of reducing the risk of daily shortfalls, ensuring adequate daily consumption for all group members who actively pool resources. Consistently high food producers who give more than they receive, however, gain the least risk-reduction benefit from this daily pooling because they are the least likely to go ...

We extend on the work developed by R.R. Poznanski and J. Bell from a linearized somatic persistent sodium current source to a non-linear representation of the dendritic Na‡P current source associated with a small number of persistent sodium channels. The main objective is to investigate the modulation in the ampli®cation of excitatory postsynaptic potentials (EPSPs) in dendrites studded with pe...

This paper presents a new discretization method for the computation of the orientation workspace of 6DOF parallel manipulators, de®ned as the set of all attainable orientations of the mobile platform about a ®xed point. The method is based on the use of a modi®ed set of Euler angles and a particular representation of the orientation workspace. In addition, the projected orientation workspace is...

We address the problem of forecasting spatial activities on a daily basis that are subject to the types of multiple, complex calendar e€ects that arise in many applications. Our problem is motivated by applications where we generally need to produce thousands, and frequently tens of thousands, of models, as arises in the prediction of daily origin±destination freight ̄ows. Exponential smoothing...

Int Clin Pathol J 2016, 2(2): 00032 locus has been identified in children of age two years or younger with various types of leukemia. Heterogeneity of the breakpoints ranging from 7q32 (very few) or q36 (frequently) and 12p13 have been reported in myeloid disorders [4-9]. We report here a case of Pediatric Acute Erythroblastic Leukemia with a variant t(7;12) translocation involving three chromo...

Analgorithm for addition and deletion (ADDEL) of resources during learning is developed to achieve two goals: (1) tofind feed-forward multilayer networks that are as small as possible, (2) tojind an appropriate structure for such small networks. These goals are accomplished by operating alternately between an adding phuse and a deleting phase while learning the given input-output associations. ...

Dynamic telepathology uses a teleoperated microscope to allow pathologists to view samples at a remote location. However, time delays introduced by remote operation have made use of a commercial dynamic telepathology system difficult and frustrating. This paper describes the iterative redesign of the user interface. We redesigned the interface, conducted experiments to evaluate the improvements...

Aging is accompanied by a continuous decline of the adrenal steroid hormone DHEA and its ester DHEAS. Results from studies in rodents have demonstrated that DHEA(S) administration can enhance memory in several test paradigms. However studies from this laboratory did not find positive effects of DHEA treatment on cognitive performance in young and elderly humans. With respect to a possible mecha...

Systems for automated image analysis are useful for a variety of tasks. Their importance is still growing due to technological advances and increased social acceptance. Especially driver assistance systems have reached a high level of sophistication. Fully or partly autonomously guided vehicles, particularly for road traffic, require highly reliable algorithms due to the conditions imposed by n...
