“Nice opinion - god of fools” Drummond of Hawthornden and folly

Cet article se fonde sur les journaux intimes de Drummond of Hawthornden (1585-1649), poète et homme de lettres écossais, pour essayer de comprendre en quoi la folie était significative pour lui. Quelle était, dans son esprit, la relation entre la folie et la représentation publique du soi, la réputation ou encore la connaissance de soi ? Par ailleurs, les idées de Drummond sur la folie auraient-elles pu contraindre sa production créative

Portable Sawmilling Costs for Landholders in Western Queensland

Portable sawmilling trials with Acacia aneura (mulga) and A. cambagei (gidgee) have been undertaken to estimate the private landholder costs associated with small-scale timber production from woodlands in western Queensland, Australia. A time study of harvesting and milling operations facilitated estimation of landholder labour input requirements. The scarcity and small size of millable logs, coupled with the prevalence of timber defects, make harvesting and portable sawmilling of western Queensland acacias an expensive undertaking for landholders. The cost of producing sawn timber that meets the High Feature (HF) grade of Australian Standard AS2796 is estimated at between A$3,000-m3 and A$3,400/m3 of HF timber.

Short Selling in a Financial Crisis: The Regulation of Short Sales in the United Kingdom and the United States

In a well-regulated market with minimal risk of abuse, the liquidity and information efficiency benefits of short selling far outweigh its potential harm. Contrary to the recent hostility short sellers face from market regulators and the popular press, short sellers in aggregate are neither market villains nor agents of destruction. While a small minority of short sellers have exploited lax regulation and inattentive enforcement of anti-abuse rules to manipulate stock prices and earn substantial fees, these rare episodes suggest that the world\u27s major capital markets need better enforcement of existing rules and not new rules per se. The failure of market regulators to prevent abuse and manipulation of stock prices by short sellers and curb naked short selling reflects a failure of enforcement, not bad underlying policy. This comment outlines past attempts to regulate short selling, explains the emergency regulations enacted in 2008 in response to the financial crisis, and offers a series of recommendations for policymakers as they contemplate a new era of short sale regulation designed to match the pace of modern capital markets and the character of modern investors

Monitoring at-home care patients through a scalar polar plot visualization of motion sensor data

In Canada, approximately 18 percent (6.6 million) of the total population are age 65 or older, and 88 percent of people over age 65 want to stay in their residence for as long as possible. This older demographic is a group that is dependent on proactive and preventative healthcare. Using motion sensor data collected from a local company providing home-care services to this demographic, a data visualization was constructed to assist users in observing patient behavior and improving their quality of life while maintaining their independence. However, since the collected data is time-based, it results in a dataset that is too large to plot and determine behavior from. The goal of this project was to take an existing polar plot visualization created from the data over a period of one month and scale it to display data over a larger time frame of at least 6 months, allowing us to determine patient behavioral changes over time. This was achieved by using a weighted random sampling method and implemented using Python, Pandas, PlotlyExpress and Dash. As a result of this project, weighted random sampling enabled the viewer to determine behavioral changes and abnormalities using the polar plot visualization over a period of 6 months

Reconnection of Vortex Tubes with Axial Flow

This paper addresses the interaction of initially anti-parallel vortex tubes containing an axial flow that induces a twisting of the vortex lines around the tube axes, using numerical simulations. Vortex tube configurations with both the same and opposite senses of twist -- corresponding to same and opposite signs of kinetic helicity density -- are considered. It is found that the topology of the reconnection process is very different between the two cases. For tubes with the same sense of twist, the reconnection is fully three-dimensional (3D): vortex lines reconnect at a finite angle, and 3D vortex null points may be created. Following reconnection the vortex line topology in both bridge and thread structures exhibits a high degree of complexity. For oppositely-twisted tubes the reconnection is locally two-dimensional, occurring along vorticity null lines, that in contrast to the untwisted case are not perpendicular to the tube axes. This leads to a break in the symmetry between the two vortex bridges generated during reconnection. For all cases studied, increasing the twist in the vortex tubes leads to a later, faster, and more complete reconnection process.Comment: Accepted for publication in Physical Review Fluid
