Hypercube matrix computation task

A major objective of the Hypercube Matrix Computation effort at the Jet Propulsion Laboratory (JPL) is to investigate the applicability of a parallel computing architecture to the solution of large-scale electromagnetic scattering problems. Three scattering analysis codes are being implemented and assessed on a JPL/California Institute of Technology (Caltech) Mark 3 Hypercube. The codes, which utilize different underlying algorithms, give a means of evaluating the general applicability of this parallel architecture. The three analysis codes being implemented are a frequency domain method of moments code, a time domain finite difference code, and a frequency domain finite elements code. These analysis capabilities are being integrated into an electromagnetics interactive analysis workstation which can serve as a design tool for the construction of antennas and other radiating or scattering structures. The first two years of work on the Hypercube Matrix Computation effort is summarized. It includes both new developments and results as well as work previously reported in the Hypercube Matrix Computation Task: Final Report for 1986 to 1987 (JPL Publication 87-18)

New World Origins of Southwest Pacific Gesneriaceae: Multiple Movements Across and Within the South Pacific

Coronanthereae is a tribe of ~20 species with a suite of unique morphological characters and a disjunct geographic distribution in the Southern Hemisphere. Three species are found in southern South America and the remainder in the southwest Pacific. It has been suggested, because of this distribution and disjunction, that Coronanthereae represents a relictual Gondwanan group from which the two major lineages in the family, the Old World Cyrtandroideae and the New World Gesnerioideae, originated. We tested this hypothesis by using phylogenetic analyses of nuclear and chloroplast DNA sequences, ancestral-area reconstruction, and molecular dating. The tribe is placed within the mostly Neotropical subfamily Gesnerioideae and comprises three lineages, treated here as subtribes. Two events of dispersal from South America explain the presence of the tribe in the South Pacific. Negriinae, newly recognized here, comprises arborescent genera: Australian Lenbrassia, New Caledonian Depanthus, and Negria from Lord Howe Island. Mitrariinae groups facultatively epiphytic Australian Fieldia with epiphytes from South America, a finding inconsistent with recent placement of Lenbrassia in synonymy of Fieldia. Coronantherinae consists of the arborescent Coronanthera from New Caledonia and the shrub Rhabdothamnus from New Zealand. Ancestral-area reconstruction and molecular dating of the clades support long-distance dispersal mechanisms, rather than Gondwanan vicariance, for explaining geographic distributions

Cuba and the Secret World

© 2019, © 2019 Informa UK Limited, trading as Taylor & Francis Group. This article explores the career of Maj. Juan Rodríguez, who served in Cuban intelligence from 1958 to 1987. It discusses the origins and nature of the Castro regime’s security and intelligence services, including the development and prioritization of their missions. It identifies the milestones that defined these services’ institutional history. It connects this history to US–Cuban relations in the post-Cold War period. And it proposes a research agenda that will contribute to more equitable and integrated approaches to the modern and contemporary history of the Americas and the developing world, and to more diverse and representative security and intelligence studies

The Effect of CardioWaves Interval Training on Resting Blood Pressure, Resting Heart Rate, and Mind-Body Wellness

International Journal of Exercise Science 9(1): 89-100, 2016. An experimental study to examine the effects of CardioWaves interval training (CWIT) and continuous training (CT) on resting blood pressure, resting heart rate, and mind-body wellness. Fifty-two normotensive (blood pressure \u3c120/80 mmHg), pre-hypertensive (120–139/80–89 mmHg), and hypertensive (\u3e140/90 mmHg) participants were randomly assigned and equally divided between the CWIT and CT groups. Both groups participated in the assigned exercise protocol 30 minutes per day, four days per week for eight weeks. Resting blood pressure, resting heart rate, and mind-body wellness were measured pre- and post-intervention. A total of 47 participants (15 females and 32 males) were included in the analysis. The CWIT group had a non-significant trend of reduced systolic blood pressure (SBP) and increased diastolic blood pressure (DBP) while the CT group had a statistically significant decrease in awake SBP (p = 0.01) and total SBP (p = 0.01) and a non-significant decrease in DBP. With both groups combined, the female participants had a statistically significant decrease in awake SBP (p = 0.002), asleep SBP (p = 0.01), total SBP (p = 0.003), awake DBP (p = 0.02), and total DBP (p = 0.05). The male participants had an increase in SBP and DBP with total DBP showing a statistically significant increase (p = 0.05). Neither group had a consistent change in resting heart rate. Both groups showed improved mind-body wellness. CWIT and CT reduced resting blood pressure, with CT having a greater effect. Resting heart rate did not change in either group. Additionally, both CWIT and CT improved mind-body wellness

The carbon dioxide combining power of the blood plasma, its determination and its significance in certain pathological conditions

1. There is a marked fall in the CO₂ combining power of the blood plasma in states of uraemia as estimated by the Van Slyke apparatus.2. Relative normal in Chronic Interstitial Nephritis where there is no clinical evidence of uraemia.3. If the CO₂ combining power reading of the blood plasma remains high then less likelihood of uraemia supervening.4. Suggested early treatment of uraemia before definite clinical signs of this condition appear if one finds the reading of the CO₂ combining power commencing to fall.5. Patient is more likely to die suddenly of cerebral haemorrhage than go into uraemic coma if the CO₂ combining power reading remains high. It is in cases of high blood pressures:- all the cases I have mentioned had relatively high blood pressures.)6. CO₂ combining power reading of the blood plasma is of useful diagnostic value in comatose or semi-comatose patients. If the CO₂ combining power reading is high then less likelihood of patient being in uraemic coma,7. If CO₂ combining,power reading is low in an unconscious patient and after examination of urine no sugar is found, the patient is likely to be in uraemic coma.8. Findings are not so low in this short series of cases as others have found (i.e. the CO₂ combining power readings of the blood plasma).9. There is no particular correlation between the CO₂ combining power findings and the blood chemistry findings.10. CO₂ combining power readings useful in diagnosis of epileptic seizures from uraemic convulsions, if any dubiety should arise in the diagnosis.11. Relative lowness of supposed normal figures found as compared to those found by Van Slyke, Dunlop Stewart and others

Executive Education: Can it Be Too Good?

A successful business school must serve two communities: the research community on one hand; and the business community on the other. However, despite the spectacular growth of business education over the last four or five decades, there has been growing criticism of the relevance of much business school activity: The academic-practitioner divide has emerged and largely refuses to close. To bridge the gap b-schools must serve both communities concurrently. Executive education is identified as being a critical strategy in the repertoire of b-school deans through which to do so. The aim of this paper is to discuss the construct of executive education, and to challenge some of the dominant logics that executive education is simply education for executives. Executive education is reported as being distinctive from most content focused education – the tangible material that most universities teach. The successful design and delivery of a suite of non-credit executive education courses, with a focus on corporate and institutional governance, is presented. Their underpinning pedagogy, based on developing a critically reflective practitioner, is discussed. Executive education courses are found to be distinctive on the basis that responsibility for learning, and the direction of the journey being taken, rests largely with the participants themselves. The adverse reaction to a six month long not-for-credit short course, offered in-house annually for four years is then briefly described. Observations are shared as to the source of this reaction. The means of avoiding similar adversity towards effective executive education in the future is then identified
