Finite volume scheme for the lattice Boltzmann method on unstructured meshes

Abstract: Department of Mathematics and Statistics, Bowling Green State University, Bowling Green, Ohio 43403~Received 9 September 1998!A finite volume scheme for the lattice Boltzmann method is developed for unstructured triangular meshes intwo dimensions. The accuracy of this new scheme is demonstrated by comparing the numerical results with theexact solutions to the Navier-Stokes equations for Taylor vortex flow, shear flow between two parallel plates,shear flow between two rotating cylinders, and Poiseuille flow. The agreement between the numerical andanalytical results is very good for each of these tests. @S1063-651X~99!07804-6#PACS number~s!: 47.10.1g, 47.11.1j, 05.20.DdI. INTRODUCTION

Religious coping among psychotic patients: relevance to suicidality and treatment outcomes.

Abstract: Religious coping is very common among individuals with psychosis, however its relevance to symptoms and treatment outcomes remains unclear. We conducted a prospective study in a clinical sample of n¼47 psychiatric patients with current/past psychosis receiving partial (day) treatment at McLean Hospital. Subjects completed measures of religious involvement, religious coping and suicidality prior to treatment, and we assessed for psychosis, depression, anxiety and psychological well-being over the course of treatment. Negative religious coping (spiritual struggle) was associated with substantially greater frequency and intensity of suicidal ideation, as well as greater depression, anxiety, and less well-being prior to treatment (accounting for 9.0–46.2% of the variance in these variables). Positive religious coping was associated with significantly greater reductions in depression and anxiety, and increases in well-being over the course of treatment (accounting for 13.7–36.0% of the variance in change scores). Effects remained significant after controlling for significant covariates. Negative religious coping appears to be a risk factor for suicidality and affective symptoms among psychotic patients. Positive religious coping is an important resource to this population, and its utilization appears to be associated with better treatment outcomes. & 2013 Elsevier Ireland Ltd. All rights reserved.

Recognition of Dominance Status By Chemoreception in the Red Swamp Crayfish, Procambarus clarkii

Abstract: We tested the hypothesis that chemical signals play a role in the recognition of dominance status in the red swamp crayfish, Procambarus clarkii. Dominance was judged on the outcome of dyadic interactions in all male or female groups of three individuals. This resulted in a dominant, intermediate, and subordinate individual within each population. A choice paradigm in a flow-through Y maze was used to judge whether crayfish were able to recognize dominance through chemical cues alone. Both individuals that interacted with the animal producing the odor and naive individuals were tested. Irrespective of sex and previous experience, individuals increased their rates of locomotion in the presence of conspecific odor. Naive males investigated the dominant arm first, spent more time at the dominant nozzle, and responded more aggressively (as measured by meral spread) to dominant male odor and subordinate female odor. Intermediate males spent more time at the dominant male nozzle and responded more aggressively to dominant male odor. Naive females spent more time at the dominant nozzle. These results show that males recognize dominant animals. Since both naive and experienced males respond to water from dominant animals, we concluded that this is recognition of dominance and not just individual recognition. This signal may be important for the formation or reinforcement of dominance relationships. Based on the change in behavior between odors, we suggest that crayfish can use chemical cues to recognize the dominance status of conspecifics.
