Characterizing the weather band variability of the Texas shelf current

Considering the benefits of understanding the circulation patterns of the shelf, it is not surprising that there are numerous studies of the Texas Shelf circulation patterns. Given that previous studies were focused on the low-frequency variability of the circulation which is upcoast (northeast flow) in the summer and downcoast (southwest flow) especially on the inner shelf in the non-summer seasons, this study investigates the weather band (2–15 days) variability of the Texas Shelf near-surface circulation pattern. Current meter data at 1.5 m below the sea surface from the inner, mid, and outer shelves were analyzed. This study demonstrated that there are high-frequency current reversals within the weather band in each season. From the estimated persistence of the currents during reversals, the inner and mid shelf currents are predominantly downcoast in the non-summer seasons and upcoast in the summer season whereas the outer shelf currents are mostly upcoast all year round. The Wavelets analysis of the currents revealed that most of the variabilities on the inner and mid shelf regions were within the 4-12-day band whereas on the outer shelf the dominant variability was within the 3–8-day band. From the cross-spectra analysis of both the currents and wind data, it was determined that the influence of the wind was more dominant on the inner and mid shelf regions at the 8–15-day band than on the outer shelf where the contribution of the wind is prevalent at the 2–4-day band

Discovery of ((<i>S</i>)-5-(Methoxymethyl)-7-(1-methyl-1<i>H</i>-indol-2-yl)-2-(trifluoromethyl)-4,7-dihydropyrazolo[1,5-<i>a</i>]pyrimidin-6-yl)((<i>S</i>)-2-(3-methylisoxazol-5-yl)pyrrolidin-1-yl)methanone As a Potent and Selective I_Kur Inhibitor

Previously disclosed dihydropyrazolopyrimidines are potent and selective blockers of I_Kur current. A potential liability with this chemotype is the formation of a reactive metabolite which demonstrated covalent binding to protein in vitro. When substituted at the 2 or 3 position, this template yielded potent I_Kur inhibitors, with selectivity over <i>h</i>ERG which did not form reactive metabolites. Subsequent optimization for potency and PK properties lead to the discovery of ((<i>S</i>)-5-(methoxymethyl)-7-(1-methyl-1<i>H</i>-indol-2-yl)-2-(trifluoromethyl)-4,7-dihydropyrazolo­[1,5-<i>a</i>]­pyrimidin-6-yl)­((<i>S</i>)-2-(3-methylisoxazol-5-yl)­pyrrolidin-1-yl)­methanone (<b>13j</b>), with an acceptable PK profile in preclinical species and potent efficacy in the preclinical rabbit atrial effective refractory period (AERP) model

An Assessment of the Current State of Cybercrime Scholarship

Computers and the Internet have become a vital part of modern life across the world, affecting communications, finance, and governance. At the same time, technology has created unparalleled opportunities for crime and deviance on- and off-line. Criminological research has expanded its focus over the last two decades to address the various forms of technology-enabled crime and the applicability of traditional theories to account for offending. There is, however, a need for careful consideration of the state of the field in order to identify issues requiring further study and analysis. This study examines the current literature on virtually all forms of cybercrime and the theoretical frameworks used to address these issues. In turn, we hope to give direction to refine our understanding of criminological theory and social policies to combat these offenses

Plant size, latitude, and phylogeny explain within-population variability in herbivory

Interactions between plants and herbivores are central in most ecosystems, but their strength is highly variable. The amount of variability within a system is thought to influence most aspects of plant-herbivore biology, from ecological stability to plant defense evolution. Our understanding of what influences variability, however, is limited by sparse data. We collected standardized surveys of herbivory for 503 plant species at 790 sites across 116° of latitude. With these data, we show that within-population variability in herbivory increases with latitude, decreases with plant size, and is phylogenetically structured. Differences in the magnitude of variability are thus central to how plant-herbivore biology varies across macroscale gradients. We argue that increased focus on interaction variability will advance understanding of patterns of life on Earth
