Preventive Cardiology in the Digital and COVID-19 Era: A Brave New World within the Veterans Health Administration

The past year challenged patients, health care providers, and health systems alike to adapt and recalibrate to meet healthcare needs within pandemic constraints. The coronavirus 2019 (COVID-19) pandemic has radically interfered with the accessibility and delivery of cardiovascular care in the United States. With an emphasis on social distancing and stay-at-home orders in effect, many Americans delayed seeking routine medical care and treatment for acute cardiac symptoms due to fear of contracting the coronavirus. The COVID-19 pandemic compelled a rapid shift toward virtual care solutions across cardiovascular domains. The U.S Department of Veterans Affairs (VA) expanded virtual modalities, notably in specialty care and rehabilitation, which offered secure solutions to maintain treatment continuity. Within the VA and other health systems, virtual cardiac rehabilitation (CR) was embraced as an efficacious alternative to on-site cardiac rehabilitation that enabled patients to receive cardiac care remotely. Leveraging the infrastructure and lessons learned from the pandemic-induced expansion of virtual care carries enormous potential to refine virtual CR and revitalize future treatment paradigms for cardiovascular disease patients.
Wellenbeanspruchung auf hydrodynamisch kompakte Betonstrukturen für Offshore‐Windenergieanlagen

Für die Ermittlung von Wellen‐ und Strömungslasten auf Offshore‐Gründungskonstruktionen wird häufig die Morison‐Gleichung verwendet. Diffraktionseffekte und vertikale Kraftanteile werden von ihr nicht berücksichtigt. Dass dies nicht nur an hydrodynamisch kompakten Gründungsstrukturen zu unsicheren Ergebnissen führen kann, wird durch Vergleichsrechnungen nach Morison sowie mittels CFD‐Methoden an einer Schwergewichtsgründung gezeigt. Für möglichst realistische Wellenzüge werden hierzu maßgebende Wellenparameter aus langjährigen Messzeitreihen bestimmt und in vergleichenden hydrodynamischen Analysen angesetzt. An definierten Punkten der Struktur werden die resultierenden Schubkräfte und Momente beider Verfahren für eine häufig auftretende Welle moderater Abmessungen und eine Extremwelle verglichen. Hierbei werden auch bei im Verhältnis zur Struktur sehr großen Wellen Effekte bei der Umströmung aufgezeigt, welche zu einer signifikanten Erhöhung der Beanspruchung führen. In einer alleinigen Berechnung nach Morison werden diese Effekte nicht detektiert.
Enhancing Engagement of Fathers in Web-Based Preventive Parenting Programs for Adolescent Mental Health: A Discrete Choice Experiment

Few fathers enrol in web-based preventive parenting programs for adolescent mental health, despite the evidence of the benefits associated with their participation. To inform the development of father-inclusive programs, this study used a discrete choice experiment (DCE) design to determine (a) the relative influence of number of sessions, program benefits, program participants, and user control over program content on fathers’ preferences for web-based preventive parenting programs; and (b) whether selected father characteristics were associated with their preferences. One hundred and seventy-one fathers completed the DCE survey, which comprised 25 choices between hypothetical programs. Programs that included the participant’s adolescent child (z = 10.06, p < 0.0001), or parenting partner (z = 7.30, p < 0.001) were preferred over those designed for fathers only. Participants also preferred program content that was recommended for them by experts (z = −4.31, p < 0.0001) and programs with fewer sessions (z = −2.94, p < 0.01). Program benefits did not predict fathers’ choice of program. Prior use of a parenting program, level of education, perceived role of parenting for adolescent mental health, and being part of a dual-working family were associated with preferences. Application of these findings may improve paternal enrolment in web-based preventive parenting programs.

Voltage-current characteristics of high-current pulsed discharges in SF

A high-current pulsed discharge in SF6 has been used as a closing switch for a pulsed power generator. The characteristics of a high-current pulsed discharge are not clear, since it is difficult to measure the time-dependent arc voltage accurately. In the present paper, the voltage-current characteristics and the time-dependent arc resistance of the high-current pulsed discharge in SF6 are obtained accurately from the arc current and the breakdown voltage by solving the circuit equation. The electrode separation and the pressure are changed from 0.1 to 1 cm and from 200 to 760 torr, respectively. The current rise time is about 380 ns. The minimum arc resistance occurs at the maximum arc current, and is from 0.04 to 0.1 Ω under the experimental conditions. The voltage-current characteristics in SF6, which are characterized by five phases, are similar to the characteristics in air but not in Ar.
Stability of Selected Lower Limb Joint Kinetic Parameters During Vertical Jump

Stability and consistency is a critical aspect in joint kinetic measurements. By applying a statistical technique, called sequential estimation procedure, the aim of this work was to determine the minimum number of trials required to obtain a stable mean for peak hip, knee, and ankle moments and powers during vertical jump. Nine competitive track and field sprinters (21.7 ± 3.5 yrs, 177.6 ± 4.3 cm, 70.8 ± 3.6 kg) performed 5 series of 5 double-legged maximum-height countermovement vertical jumps. From force platform and kinematic data, moment and power output were calculated for hip, knee, and ankle joints. The sequential estimation procedure applied to these data revealed that at least a 12-trial protocol is needed to establish a true measure for all the selected parameters. The mean number of trials for each variable was greater than 8 and less than 13. When hip moments were excluded from the analysis, a 10-trial protocol could be sufficient to reach a stable mean. In conclusion. the results of this stu.
Building education for the next industrial revolution: teaching and learning environmental literacy for the building professions

Resource efficient design and construction, i.e. doing more with less, contributes to decreasing the negative environmental implications of resource consumption. However, the environmental effects of buildings arise from the combination of many design and management decisions, and good environmental design and construction can avoid more than just the damage that flows from resource use. It is therefore important that students of building professions learn how the many decisions they make can help create ecology sustaining buildings, and this awareness begins in the classroom. This paper proposes a model for teaching and learning environmental literacy for tertiary students of building professions. It also argues that, in comparison with a well recognized theory for language learning, some of the conditions required for learning environmental literacy may not be present in Australian tertiary institutions. This work was commissioned for the Australian Council of Building Design Professions for the Environment Design Guide and funded by EcoRecycle Victoria.
Envelop transient analysis: a new method for the transient and steady state analysis of microwave communication circuits and systems

The two popular and general purpose simulation techniques, Time Domain Integration and Harmonic Balance, do not fulfil the requirement for analysis of microwave communication systems with arbitrary modulated carrier frequency. A new technique is presented, which overcomes this default. A dramatic saving in computer memory space and computation time is obtained with respect to the previous methods.
Is prenatal diet associated with the composition of the vaginal microbiome?

BACKGROUND The vaginal microbiome has been associated with adverse pregnancy outcomes, but information on the impact of diet on microbiome composition is largely unexamined. OBJECTIVE To estimate the association between prenatal diet and vaginal microbiota composition overall and by race. METHODS We leveraged a racially diverse prenatal cohort of North Carolina women enrolled between 1995 and 2001 to conduct this analysis using cross-sectional data. Women completed food frequency questionnaires about diet in the previous 3 months and foods were categorised into subgroups: fruits, vegetables, nuts/seeds, whole grains, low-fat dairy, sweetened beverages and red meat. We additionally assessed dietary vitamin D, fibre and yogurt consumption. Stored vaginal swabs collected in mid-pregnancy were sequenced using 16S taxonomic profiling. Women were categorised into three groups based on predominance of species: Lactobacillus iners, Lactobacillus miscellaneous and Bacterial Vaginosis (BV)-associated bacteria. Adjusted Poisson models with robust variance estimators were run to assess the risk of being in a specific vagitype compared to the referent. Race-stratified models (Black/White) were also run. RESULTS In this study of 634 women, higher consumption of dairy was associated with increased likelihood of membership in the L. crispatus group compared to the L. iners group in a dose-dependent manner (RR quartile 4 vs. 1: 2.01 [95% CI: 1.36, 2.95]). Increased intake of fruit, vitamin D, fibre and yogurt was also associated with increased likelihood of membership in L. crispatus compared to L. iners, but only among black women. Statistical heterogeneity was only detected for fibre intake. There were no detected associations between any other food groups or risk of membership in the BV group. CONCLUSIONS Higher consumption of low-fat dairy was associated with increased likelihood of membership in a beneficial vagitype, potentially driven by probiotics.
DYNAMIC MODELING AND ANALYSIS OF ALTERNATIVE FUEL CYCLE SCENARIOS IN KOREA

The Korean nuclear fuel cycle was modeled by the dynamic analysis method, which was applied to the once-through and alternative fuel cycles. First, the once-through fuel cycle was analyzed based on the Korean nuclear power plant construction plan up to 2015 and a postulated nuclear demand growth rate of zero after 2015. Second, alternative fuel cycles including the direct use of spent pressurized water reactor fuel in Canada deuterium uranium reactors (DUPIC), a sodium-cooled fast reactor and an accelerator driven system were assessed and the results were compared with those of the once-through fuel cycle. The once-through fuel cycle calculation showed that the nuclear power demand would be 25 GWe and the amount of the spent fuel will be tons by 2100. The alternative fuel cycle analyses showed that the spent fuel inventory could be reduced by more than 30% and 90% through the DUPIC and fast reactor fuel cycles, respectively, when compared with the once-through fuel cycle. The results of this study indicate that both spent fuel and uranium resources can be effectively managed if alternative reactor systems are timely implemented along with the existing reactors.
LOCOS-induced stress effects on thin-film SOI devices

LOCOS-induced stress effects on thin-film SOI devices are investigated. We show that as the field oxide thickness increases, degradation (enhancement) of nMOSFET's (pMOSFET's) I-V characteristics becomes increasingly pronounced. The total degradation or enhancement of I-V characteristics can reach /spl sim/40% of drive current for devices under certain processing conditions. Estimated stress results using four-point bending measurement show that the stress level on the silicon film is of order 1200 MPa for devices with /spl sim/40% of I-V degradation/enhancement. We attribute the stress phenomenon to the volumetric expansion of field oxide during the LOCOS process.
Bandwidth prediction for high-performance interconnections

This paper compares the major classes of chip-to-chip and on-chips interconnections used in high-performance computers and communication systems. Measurement of dielectric loss is shown and the attenuation is compared for printed-circuit-board, glass-ceramic, thin-film, and on-chip wiring. Simulation results are shown with representative driver and receiver circuits, guidelines are formulated for when losses are significant, and predictions are made for the sustainable bandwidths on useful wiring lengths.

It is regulating the traffic that can pass through a router that connecting to the network infrastructure. It is preventing from unauthorized users to access the network whether from outside via the Internet or inside, Local Area Network (LAN) itself. Firewall system has many methods and techniques that imply and describes on each of their types or technologies. This paper had discussed about how all the methods in types of firewall functioning and give the advantages and disadvantages on decision making in a network security policy especially on using firewall system.
A SVM-based method for sentiment analysis in Persian language

Persian language is the official language of Iran, Tajikistan and Afghanistan. Local online users often represent their opinions and experiences on the web with written Persian. Although the information in those reviews is valuable to potential consumers and sellers, the huge amount of web reviews make it difficult to give an unbiased evaluation to a product. In this paper, standard machine learning techniques SVM and naive Bayes are incorporated into the domain of online Persian Movie reviews to automatically classify user reviews as positive or negative and performance of these two classifiers is compared with each other in this language. The effects of feature presentations on classification performance are discussed. We find that accuracy is influenced by interaction between the classification models and the feature options. The SVM classifier achieves as well as or better accuracy than naive Bayes in Persian movie. Unigrams are proved better features than bigrams and trigrams in capturing Persian sentiment orientation.
Early Identification of Suicide Risk Factors Among Justice-Involved Youth

Suicidal thoughts and behaviors among juvenile justice populations are elevated. However, the characteristics of justice-involved youth who consider and attempt suicide are not well understood. This study examined suicidal ideation and attempt with first-time, preadjudicated diverted youth, and the relationship with commonly associated risk factors. The sample included 135 youth (50% male, Mage = 14.48) that provided complete responses to self-reported lifetime suicidal ideation and attempt items. Analyses examined relationships between suicidal ideation/attempt and mental health, child welfare involvement, delinquency, self-cutting, and substance use. First time, preadjudicated diverted youth reported high rates of lifetime suicidal ideation (27%) and attempt (17%). Suicidal ideation and attempt were associated with sexually minoritized status and self-cutting, while child welfare involvement was only associated with suicidal ideation. This high-risk population would benefit from refined suicide screening and prevention services not always available to justice-involved youth living in the community.
Simulation of annual daylighting profiles for internal illuminance

A true measure of the long-term daylighting performance of a building must account for the illumination that results from a wide range of sky and sun conditions. This paper describes how to predict hourly internal daylight illuminances for a period of a full year using sky and sun conditions derived from meteorological time-series data. The technique is based on a refined implementation of the daylight coefficient approach. The analysis and the reduction of the large datasets that result from a daylight coefficient based evaluation are described. The new approach was validated under real sky condition using the BRE-IDMP dataset and shown to be highly accurate.
Whole-limb scaling of muscle mass and force-generating capacity in amniotes

Skeletal muscle mass, architecture and force-generating capacity are well known to scale with body size in animals, both throughout ontogeny and across species. Investigations of limb muscle scaling in terrestrial amniotes typically focus on individual muscles within select clades, but here this question was examined at the level of the whole limb across amniotes generally. In particular, the present study explored how muscle mass, force-generating capacity (measured by physiological cross-sectional area) and internal architecture (fascicle length) scales in the fore- and hindlimbs of extant mammals, non-avian saurians (‘reptiles’) and bipeds (birds and humans). Sixty species spanning almost five orders of magnitude in body mass were investigated, comprising previously published architectural data and new data obtained via dissections of the opossum Didelphis virginiana and the tegu lizard Salvator merianae. Phylogenetic generalized least squares was used to determine allometric scaling slopes (exponents) and intercepts, to assess whether patterns previously reported for individual muscles or functional groups were retained at the level of the whole limb, and to test whether mammals, reptiles and bipeds followed different allometric trajectories. In general, patterns of scaling observed in individual muscles were also observed in the whole limb. Reptiles generally have proportionately lower muscle mass and force-generating capacity compared to mammals, especially at larger body size, and bipeds exhibit strong to extreme positive allometry in the distal hindlimb. Remarkably, when muscle mass was accounted for in analyses of muscle force-generating capacity, reptiles, mammals and bipeds almost ubiquitously followed a single common scaling pattern, implying that differences in whole-limb force-generating capacity are principally driven by differences in muscle mass, not internal architecture. In addition to providing a novel perspective on skeletal muscle allometry in animals, the new dataset assembled was used to generate pan-amniote statistical relationships that can be used to predict muscle mass or force-generating capacity in extinct amniotes, helping to inform future reconstructions of musculoskeletal function in the fossil record.
Automatic Representative View Selection of a 3D Cultural Relic Using Depth Variation Entropy and Depth Distribution Entropy

Automatically selecting a set of representative views of a 3D virtual cultural relic is crucial for constructing wisdom museums. There is no consensus regarding the definition of a good view in computer graphics; the same is true of multiple views. View-based methods play an important role in the field of 3D shape retrieval and classification. However, it is still difficult to select views that not only conform to subjective human preferences but also have a good feature description. In this study, we define two novel measures based on information entropy, named depth variation entropy and depth distribution entropy. These measures were used to determine the amount of information about the depth swings and different depth quantities of each view. Firstly, a canonical pose 3D cultural relic was generated using principal component analysis. A set of depth maps obtained by orthographic cameras was then captured on the dense vertices of a geodesic unit-sphere by subdividing the regular unit-octahedron. Afterwards, the two measures were calculated separately on the depth maps gained from the vertices and the results on each one-eighth sphere form a group. The views with maximum entropy of depth variation and depth distribution were selected, and further scattered viewpoints were selected. Finally, the threshold word histogram derived from the vector quantization of salient local descriptors on the selected depth maps represented the 3D cultural relic. The viewpoints obtained by the proposed method coincided with an arbitrary pose of the 3D model. The latter eliminated the steps of manually adjusting the model’s pose and provided acceptable display views for people. In addition, it was verified on several datasets that the proposed method, which uses the Bag-of-Words mechanism and a deep convolution neural network, also has good performance regarding retrieval and classification when dealing with only four views.
Static/dynamic trade-off performance of PZT thick film micro-actuators

Piezoelectric actuators are widespread in the design of micro/nanorobotic tools and microsystems. Studies toward the integration of such actuators in complex micromechatronic systems require the size reduction of these actuators while retaining a wide range of performance. Two main fabrication processes are currently used for the fabrication of piezoelectric actuators, providing very different behaviors: (i) the use of a bulk lead zirconate titanate (PZT) layer and (ii) the use of thin film growth. In this paper, we propose a trade-off between these two extreme processes and technologies in order to explore the performance of new actuators. This resulted in the design and fabrication of thick film PZT unimorph cantilevers. They allowed a high level of performance, both in the static (displacement) and dynamic (first resonance frequency) regimes, in addition to being small in size. Such cantilever sizes are obtained through the wafer scale bonding and thinning of a PZT plate onto a silicon on insulator wafer. The piezoelectric cantilevers have a 26 μm thick PZT layer with a 5 μm thick silicon layer, over a length of 4 mm and a width of 150 μm. Experimental characterization has shown that the static displacements obtained are in excess of 4.8 μm V−1 and the resonance frequencies are up to 1103 Hz, which are useful for large displacements and low voltage actuators.
