Imaging of a weak target hidden behind a scattering medium can be significantly confounded by glare. We report a method, termed coherence gated negation (CGN), that uses destructive optical interference to suppress glare and allow improved imaging of a weak target. As a demonstration, we show that by permuting through a set range of amplitude and phase values for a reference beam interfering wi...
We generalize results of earlier work on learning in Bayesian games by allowing players to make decisions in a nonmyopic fashion. In particular, we address the issue of nonmyopic Bayesian learning with an arbitrary number of bounded rational players, i.e., players who choose approximate best-response strategies for the entire horizon (rather than the current period). We show that, by repetition...
Recently, we read with great interest the article by Liu et al, which was published in your journal (Liu et al., 2010). The aim of the study was to evaluate the impact of the COX-2 gene 8473T>C polymorphism on lung cancer risk. The results indicated that the COX-2 gene was a factor for suffering from lung cancer, especially of small cell type among Asians. After carefully reading the article, w...
Theories concerning the concentration-dependence of sedimentation and diffusion coefficients for macro-molecules in dilute solution are compared and discussed, together with their experimental basis. An attempt has been made to clarify an important uncertainty still present in the literature as to whether sedimentation coefficients should be corrected for solvent or solution density. It is poin...
This paper considers a credit mechanism for selecting a unique competitive equilibrium (CE). It is shown that in general there exists a “price-normalizing” bundle, with which the enlargement of the general-equilibrium structure to allow for default subject to appropriate penalties results in a construction of a simple credit mechanism for a credit using society to select a unique CE. With some ...
Objectives. Development of a simple mutation directed method in order to allow lowering the cost of mutation testing using an easily obtainable biological material. Assessment of the feasibility of such method was tested using a GC-rich amplicon. Design and Methods. A method of denaturing high-performance liquid chromatography (dHPLC) was improved and implemented as a technique for the detectio...
When a clinician considers the results of laboratory tests (as ’good’ or ’bad’), the reference range used by the laboratory is the cornerstone and the basis of further evaluations. In the majority of laboratories healthy reference range is declared according to test descriptions and literature; just a minority perform a systematic analysis among individuals of a population considered as healthy...
Standard belief hierarchies are an insufficient description of uncertainty for the BayesianNash Equilibrium (BNE) solution concept. Two states with the same belief hierarchy profile may have different sets of BNE action profiles, for many games. We construct new hierarchy profiles with explicit beliefs about payoff irrelevant signals. We show that BNE can be described within those hierarchy pro...
We present the case of a 64-year-old man with a presumed diagnosis of extracerebral cavernous hemangioma involving the cavernous sinus. The diagnosis was made on the basis of labeled red cell blood pool scintigraphy findings in conjunction with those of MR imaging. This lesion was not altered in appearance at 6-year follow-up MR imaging. We also present the labeled red cell blood pool scintigra...
User equilibrium with recourse (UER) is a static traffic assignment equilibrium model. The model accounts for the adaptive behaviour of users when provided additional information en-route within a transport network. Similar to the traditional deterministic user equilibrium (DUE) model, this equilibrium model analytically exhibits what is known as the “Braess Paradox”. The paradox suggests that ...
