A Kosloff/Basal method, 3D migration program implemented on the CYBER 205 supercomputer

Conventional finite difference migration has relied on approximations to the acoustic wave equation which allow energy to propagate only downwards. Although generally reliable, such approaches usually do not yield an accurate migration for geological structures with strong lateral velocity variations or with steeply dipping reflectors. An earlier study by D. Kosloff and E. Baysal (Migration with the Full Acoustic Wave Equation) examined an alternative approach based on the full acoustic wave equation. The 2D, Fourier type algorithm which was developed was tested by Kosloff and Baysal against synthetic data and against physical model data. The results indicated that such a scheme gives accurate migration for complicated structures. This paper describes the development and testing of a vectorized, 3D migration program for the CYBER 205 using the Kosloff/Baysal method. The program can accept as many as 65,536 zero offset (stacked) traces

Effectiveness of Biofeedback in Improving Heart Rate Variability Recovery Following Stress

The current study was designed to examine the efficacy of heart rate variability (HRV) biofeedback using emWave, a specific biofeedback device available to the public, and to determine whether such treatment affects phasic physiological responses to stress. Twenty-seven individuals (4 males, 23 females), aged 18-30 years (M = 22.54 years, SD = 3.82) participated in the current study. Thirteen individuals were randomly assigned to a control group and received no intervention, whereas the remaining 14 participants underwent 4-8 sessions of emWave intervention. All participants attended pre-treatment and post-treatment assessment sessions during which a stressor protocol was administered; physiological data were collected during rest, during stress, and following stress. EmWave treatment did not confer changes in resting, or tonic, measures of HRV. However, participants who received emWave treatment exhibited higher parasympathetic responses (i.e., pNN50) during stress at the post-treatment session compared to their control counterparts. Significant group differences in HRV were not evident during the post-stress recovery period. Additionally, no treatment effects were evident on self-reported measures of stress, psychological symptoms, or affect administered during the pre- and post-treatment assessment visits. Overall, results from the current study, combined with previous literature, suggest that the emWave may confer some limited treatment effects by increasing HRV in response to stress. Additional development and testing of the emWave treatment protocol is necessary before it can be recommended for regular use in clinical settings, including the determination of what physiological changes occur during HRV biofeedback that contribute to any clinical effects that may occur with the emWave treatment

The introduction of forgiveness into a path analytical model of the association between parental divorce and adult attachment

Several factors (i.e., parental divorce, parent-child relationship quality, interparental conflict, individual forgiveness) that have been investigated separately in relation to adult romantic attachment were examined alongside family forgiveness, which has not previously explored in relation to attachment. Undergraduate students (N = 299) completed several surveys online for the current study. Several significant findings emerged when factors were considered in path models individually, and in an overall path model built on the basis of those individual model findings. Maternal and paternal social support, maternal negative interactions, and family forgiveness were moderators of parental divorce---romantic attachment relations. Based upon these findings, it was concluded that (1) several factors should be accounted for beyond parental divorce when considering the link between parental marital status and romantic attachment in young adulthood, and (2) family and individual forgiveness, which have not been studied as extensively as other factors in the relevant literature, should also be included in future investigations of romantic attachment

Free drifting buoy trajectories in the Gulf Stream system : 1975-1978 : a data report

From 1975 to 1978, thirty-one satellite-tracked free-drifting surface buoys were launched in the Gulf Stream system. Most of these buoys were launched in cyclonic rings, as part of an interdisciplinary Gulf Stream ring experiment, Other buoys were launched in anticyclonic rings and the Gulf Stream itself; one buoy was launched in a cyclonic Kuroshio ring. The basic data set consists of buoy trajectories and sea surface temperature and velocity measurements along trajectories. The main results consist of a series of 19 buoy trajectories in rings from which the movement of rings is inferred and a series of 20 buoy trajectories in the Gulf Stream. Rings frequently coalesced with the Gulf Stream, and some reformed as modified rings. The trajectories of buoys in the Stream reveal that at times surface currents are strongly influenced by topographic features such as seamounts and ridges. Most buoys in the Stream continued to move eastward until they reached the vicinity of the Grand Banks (50°W) where they rapidly fanned out, some moving northward, others eastward across the mid-Atlantic Ridge, still others southward and westward .Prepared for the Office of Naval Research under Contract N00014-74-C-0262; NR 083-004 and for the National Science Foundation under Grants OCE 75-008765 and OCE 77-08045

The role of the N-terminus of the Cav2.2 voltage-dependent calcium channel in the inhibition by G-proteins

The neuronal Cay2.2 calcium channel is inhibited by Gpy subunits of heterotrimeric G-proteins in a voltage-dependent manner. It has been shown previously that an 11 amino acid motif (44-55) in the intracellular N-terminus of Cav2.2al (aiB) is essential for G-protein modulation of currents. Mutation of 2 amino acids, R52 and R54, in this region completely abolishes G-protein inhibition. They may form part of the G0y binding site, or translate binding into a functional response. To investigate the role of the N-terminus of the Cay2.2ai subunit I have expressed functional channels in Xenopus oocytes and recorded currents using the two-electrode voltage-clamp technique. To examine further the role of the N-terminus I have tethered it to the membrane via an N-terminal palmitoylation motif and I have also used an isolated N-terminus. The palmitoylation motif Cav2.2ai showed reduced modulation by G(3y (lower facilitation ratio and reduced GPCR activated inhibition). Other additions on the N-terminus such as GFP or a HA-tag, also reduced modulation. However, only the palmitoylation motif Cay2.2ai showed an increase in the rate of loss of G-protein modulation during depolarisation (faster facilitation rate). This increase in facilitation rate is unique to the palmitoylation motif Cav2.2ai. The increased facilitation rate may be due to a reduction in the affinity of the channel for Gfiy because of the reduced mobility of the N-terminus

Insights from Monitoring Aspirin Adherence: A Medication Adherence Cascade Tool

Background: Adherence to recommended medications is a key issue in the care of patients with cardiovascular disease (CVD) and barriers to adherence are well established during the medication adherence cascade, the processes of prescribing, obtaining, taking, and maintaining medication use. Aspirin avoids many of the barriers in the medication adherence cascade as it does not require a prescription (prescribing) and is inexpensive, easily accessible (obtaining), prescribed once-daily (taking) as an over-the-counter medication and is generally perceived by patients as safe (maintaining). The purpose of this paper is to report aspirin adherence and propose the Medication Adherence Cascade Tool to assist clinicians to consider all aspects of medication adherence. Methods: Adherence to aspirin was monitored with an electronic pillbox. Frequency analysis, independent T-tests, and ANOVA were completed on 151 patients with underlying heart failure who were prescribed aspirin within a larger parent study. Chi-square tests were completed to assess differences in baseline demographic characteristics. Findings: Mean aspirin adherence was 82.2% overall, with 11.9% of sample with adherence ≤ 50%, 18.5% with adherence 50–80%, and 69.5% with adherence ≥80%. Greater adherence was observed in self-identified White as compared to Black patients (84.47% vs 73.53%; p = 0.014), and patients ≥70 years of age compared to \u3c70 years (87.00% vs 77.49%; p = 0.009). Interpretation: Aspirin adherence was suboptimal despite the fact that it addresses most of the barriers on the medication adherence cascade (ie, relatively easy access, low cost, and low risk). A Medication Adherence Cascade Tool (MACT) is proposed as a clinical guide to facilitate patient–provider co-production of strategies to address medication adherence. The tool can assist patients and providers to co-produce adherence to achieve optimal medication benefits

Exploring Possibilities of Predicting Positive Counselor Qualities in Counseling Students from Personality Domains

In this pilot study, the authors investigated the degree that Big Five personality domains may predict the positive counselor qualities among 160 students enrolled in sections of a combined undergraduate/graduate Counseling Skills course. Positive counselor qualities of focus in this study are empathy, mindfulness or self-awareness, and unconditional positive self-regard in students studying counseling skills. The results do not suggest a significant predictive role for the Big Five personality domains for the Counseling Skills students, except that the Big Five domain of neuroticism predicted enough variation in mindfulness and unconditional positive self-regard to be practically significant. Limitations and potential implications of these findings for counselor educators and for future research are discussed
