People behave differently in the presence of other people than they do when they are alone. People also may behave differently when designers introduce more human-like qualities into computer interfaces. In an experimental study we demonstrate that people's responses to a talking-face interface differ from their responses to a text-display interface. They attribute some personality Lee Sproull ...

Recently, the demand for high voltage and high power IGBTs has been increasing. In order to achieve a device structure with high voltage blocking capability in the 1,200V range, the non-punch-through (NPT) type with non-buffer layer IGBT has become popular. Commercially available devices today in the 600 V range are mainly PT type, and in the 1,200 V range are mainly NPT type. These two device ...

Two studies examined attachment style differences in social perception. In Study 1, participants wrote open-ended explanations for hypothetical relationship events and described how they would feel and behave in response to each event. Compared with secure participants, preoccupied participants explained events in more negative ways; they also reported more emotional distress and behaviors that...

Analysis of HLA-associated susceptibility to insulindependent diabetes mellitus (IDDM) has largely focused on identifying the susceptibility gene. Adherents of a countertrend have long suggested the importance of analysis of HLA haplotypes (combinations of alleles on 1 chromosome) rather than individual genes. Accumulating data suggest that the relationship between IDDM susceptibility and HLA i...

Early approaches to mathematically abstracting websurfing behavior were largely based on first-order Markov models. Most humans however do not surf in a “memoryless” fashion, rather they are guided by their timedependent situational context and associated information needs. This belief is corroborated by the non-exponential revisit times observed in many site-centric weblogs. In this paper, we ...

Insects are generally described as essentially blind to red wavelengths but sensitive to ultraviolet. Therefore, ants are generally reared in nests where "obscurity" is obtained by the use of a red filter. Yet, no study has been done in order to confirm this idea and to verify whether ants behave differently with or without red light. We performed aggregation experiments with the ant Lasius nig...

Background Patients presenting with large surface area burns are common in our practice; however, patients with a secondary large burn on pre-existing burn scars and grafts are rare and not reported. Case presentation We report on an unusual case of a patient sustaining a secondary large burn to areas previously injured by a burn from a different mechanism. We discuss the potential implicatio...

Modeling of the land surface water-, energy-, and carbon balance provides insight into behavior Earth System, under current future conditions. Currently, there exists a substantial variability between model outputs, for range types, whereby differences input parameters could be an important reason. For large-scale surface, hydrological, crop models, soil hydraulic properties (SHP) are required ...

We investigate the asymptotic symmetry group of a scalar field minimally-coupled to an abelian gauge using Hamiltonian formulation. This extends previous work by Henneaux and Troessaert on pure electromagnetic case. deal with minimally coupled massive massless fields find that they behave differently insofar as latter do not allow for canonically implemented boost symmetries. also consider Higg...

Romer et al (ASPLOS 96) examined several interpreters and concluded that they behave much like general purpose integer programs such as gcc. We show that there is an important class of interpreters which behave very differently. Efficient virtual machine interpreters perform a large number of indirect branches (3.2%–13% of all executed instructions in our benchmarks, taking up to 61%-79% of the...
