Background: Esophagectomy is considered to be the main treatment for esophageal malignancies. Among the different methods, transhiatal approach can cause less damage to patients and is widely used however, manipulation of esophagus result in heart rate and blood pressure variations. The aim of this study was to investigate changes in blood pressure and heart rhythm during transhiatal esophagect...

Product ratings have become an integral element of online businesses especially for experience goods, yet seem to be prone to biases that shift most of the distribution towards the extreme points of the scales. Response biases due to inherent traits (such as acquiescence or extreme response style) are widely investigated in survey design and marketing research, yet little is known about how the...

Most efforts at automatically creating multilingual lexicons require input lexical resources with rich content (e.g. semantic networks, domain codes, semantic categories) or large corpora. Such material is often unavailable and difficult to construct for under-resourced languages. In some cases, particularly for some ethnic languages, even unannotated corpora are still in the process of collect...

(UAC) like characteristics of an S-CSCF. To show its efficiency, the session transfer delay and the traffic cost of RSA session transfer are investigated and compared with those of existing session transfer applications, including Assured and Consultative session transfers, by practically considering multiple session transfer failures. It is shown that RSA session transfer can further improve u...

Behavioral economics tells us that emotions can profoundly affect individual behavior and decisionmaking. Does this also apply to societies at large, i.e. can societies experiencemood states that affect their collective decision making? By extension is the public mood correlated or even predictive of economic indicators? Here we investigate whether measurements of collective mood states derived...

While Hall (1978) argues that the solution for consumption of a life-cycle model with uncertainty and isoelastic preferences evolves as a random walk in first order approximation around small income shocks, I show that it does not. First, I explain that the solution for consumption departs from a random walk because of precautionary behavior. A prudent household facing uncertainty allocates mor...

Accounts of mental content rooted in asymmetric dependence hold, crudely speaking, that the content of a mental representation is the cause of that representation on which all its other causes depend.1 To speak somewhat less crudely, such accounts, hereafter “AD accounts”, hold 1) that (a) any nomic relations which obtain between, on the one hand, a mental representation and, on the other hand,...

Exemplar and distributional accounts of categorization make differing predictions for the classification of a critical exemplar precisely halfway between the nearest exemplars of two categories differing in variability. Under standard conditions of sequential presentation, the critical exemplar was classified into the most similar, least variable category, consistent with an exemplar account. H...

∗ Talk given at ACAT 2000, Fermilab, Batavia, IL, October 16–20, 2000. To be published in Advanced Computing and Analysis Techniques in Physics Research, edited by: P.C. Bhat and M. Kasemann. We denote the generic two-loop tensor crossed (or non-planar) four-point function in D dimensions of Fig. 1 with seven propagators Ai raised to arbitrary powers νi as Xbox (ν1 . . .ν7;s,t) [1; k; l; kμkν; ...

Designing fair and unbiased metrics to measure the “level of excellence” of a scientist is a very significant task because they recently also have been taken into account when deciding faculty promotions, when allocating funds, and so on. Despite criticism that such scientometric evaluators are confronted with, they do have their merits, and efforts should be spent to arm them with robustness a...
