The presence of several naturally occurring amino acids in the serosal bath of toad urinary bladder significantly alters the hydrosmotic response of this tissue to vasopressin. We found that histidine, glutamate, and lysine increase vasopressinstimulated water flow by 75%, 60%, and 43%, respectively. In contrast, alanine did not alter vasopressin-stimulated water flow, whereas glutamine decreas...
When a stimulus-response event is frequently paired with a specific foreperiod, response performance for this event is improved after this foreperiod. This phenomenon is referred to as specific temporal expectancy. In four experiments, we investigated whether stimulus- or response-related processing benefits from specific temporal expectancy. In a speeded choice reaction task, different feature...
This paper will investigate the effect of digital filtering on the operating time of a generic digital distance relay. Two popular filtering approaches will be considered: the Cosine Filter and the Fourier Filter. The effects of several variables, such as sampling rate, fault location, fault incidence angle, and non-fundamental frequencies, will be discussed. This paper will attempt to discuss ...
We have studied the AC response of a hopping model in the variable range hopping regime by dynamical Monte Carlo simulations. We find that the conductivity as function of frequency follows a universal scaling law. We also compare the numerical results to various theoretical predictions. Finally, we study the form of the conducting network as function of frequency.
This paper assesses and compares the performance of generalized linear models (GLM) with respect to log transformation and ANOVA approaches on the basis of coverage results and expected length of confidence intervals (CI) for the expected responses for exponentially distributed response variable. We also focus on the power functions of tests of hypothesis for testing significance of underlying ...
We present a retrospective review of four patients treated with infliximab (5 mg ⁄ kg) for recalcitrant hidradenitis suppurativa (HS). Data including gender, age, previous treatments and therapeutic response are recorded in Table 1. All patients were screened beforehand with a chest X-ray and a Mantoux test to exclude concomitant TB. Patients 1 and 2. Our first two patients were middle-aged wom...
Human cells derived from various organs of a single embryo responded variably to polyinosinic-polycytidylic acid with respect to induction of antiviral resistance and interferon.
The random forest method is a commonly used tool for classification with high-dimensional data that is able to rank candidate predictors through its inbuilt variable importance measures (VIMs). It can be applied to various kinds of regression problems including nominal, metric and survival response variables. While classification and regression problems using random forest methodology have been...
Intratumoral heterogeneity arises through the evolution of genetically diverse subclones during tumor progression. However, it remains unknown whether cells within single genetic clones are functionally equivalent. By combining DNA copy number alteration (CNA) profiling, sequencing, and lentiviral lineage tracking, we followed the repopulation dynamics of 150 single lentivirus-marked lineages f...
