Viscosity Solutions of Hamilton–Jacobi Equations for Neutral-Type Systems
No full textThe paper deals with path-dependent Hamilton–Jacobi equations with a coinvariant derivative which arise in investigations of optimal control problems and differential games for neutral-type systems in Hale’s form. A viscosity (generalized) solution of a Cauchy problem for such equations is considered. The existence, uniqueness, and consistency of the viscosity solution are proved. Equivalent definitions of the viscosity solution, including the definitions of minimax and Dini solutions, are obtained. Application of the results to an optimal control problem for neutral-type systems in Hale’s form are given. © 2023, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.Russian Science Foundation, RSF: 21-71-10070This work is supported by a Grant of the RSF No. 21-71-10070, https://rscf.ru/project/21-71-10070
The new work order: ensuring young Australians have skills and experience for the jobs of the future, not the past
No full textEconomic changes are transforming work through automation, globalisation, and more flexible work.
Overview
Work has long been important for the livelihood, dignity, and happiness of humankind. We intuitively and statistically know that work helps us meet our most basic and complex needs, providing a path towards financial security, mental and physical health, dignity and meaning. For at least the past century, the prospect of a good job that pays a fair wage has been part of Australia’s promise to our young people. By many measures, Australia has continued to deliver on its promise. We have enjoyed relatively strong economic growth, high wages and low levels of unemployment.
But beneath the seemingly benign surface of Australia’s labour market, there is a quiet revolution occurring in the way we work. The old ‘blue collar’ part of workforce is barely recognisable today. As the factories in our urban manufacturing suburbs have been closed down or automated, the manual jobs they once provided have been decimated. Over the past 25 years, we have lost around 100,000 machinery operator jobs, nearly 400,000 labourers, and nearly 250,000 jobs from the technicians and trades. Offsetting these losses, there has been an explosion of more than 400,000 new jobs in community and personal services. The work revolution is no less visible in what we used to call ‘white collar’ jobs. Computers have swept through corporate towers and small business offices, displacing nearly 500,000 secretaries and clerks. At the same time, the increasing complexity of business processes and financial markets has created 700,000 new jobs across the professional and business services.
While our unemployment rate may be low, our factory floor workers have not seamlessly switched their hard hats for a healthcare job. Instead, unskilled workers, especially men, have stepped out of the labour force on mass. Over the past 25 years, nearly one in ten unskilled men lost their jobs and did not return to the labour force. Today, more than one in four unskilled men don’t participate. Big economic shifts are not costless for everyone

The global governance of genetic enhancement technologies: Justification, proposals, and challenges
No full textThe prospect of human genetic enhancement requires an institutional response, and probably the creation of new institutions. The governance of genetic enhancement technologies, moreover, needs to be global in scope. In this article, I analyze the debate on the global governance of human genetic enhancement. I begin by offering a philosophical justification for the need to adopt a global framework for governance of technologies that would facilitate the improvement of non-pathological genetic traits. I then summarize the main concrete proposals that have recently emerged to govern genome editing at the global level. Finally, I develop some impediments that limit the impetus for global governance of genetic enhancement.The author thanks the funding from a US-Spain Fulbright grant, an INPhINIT Retaining Fellowship of the La Caixa Foundation (Grant number LCF/BQ/DR20/11790005), and Conselho Nacional de Desenvolvimento Científico e Tecnológico (421523/2022-0)
Draft genome of the filarial nematode parasite Brugia malayi
No full textParasitic nematodes that cause elephantiasis and river blindness threaten hundreds of millions of people in the developing world. We have sequenced the approximately 90 megabase (Mb) genome of the human filarial parasite Brugia malayi and predict approximately 11,500 protein coding genes in 71 Mb of robustly assembled sequence. Comparative analysis with the free-living, model nematode Caenorhabditis elegans revealed that, despite these genes having maintained little conservation of local synteny during approximately 350 million years of evolution, they largely remain in linkage on chromosomal units. More than 100 conserved operons were identified. Analysis of the predicted proteome provides evidence for adaptations of B. malayi to niches in its human and vector hosts and insights into the molecular basis of a mutualistic relationship with its Wolbachia endosymbiont. These findings offer a foundation for rational drug design

Significant internal waves and internal tides measured northeast of Taiwan

The definitive version was published in Journal of Marine Research 71 (2013): 47-81, doi:10.1357/002224013807343416.Internal gravity waves in an area northeast of Taiwan are characterized using data from multiple sensor types. The data set includes intermittent information collected from a ship and short time series from moorings. Modeled nonlinear waves are fitted to observed nonlinear waves to provide self-consistent estimates of multiple wave parameters. A nonlinear internal wave of over 50 m amplitude, observed in deep water, is examined in detail. This wave was moving northward from the southern Okinawa Trough toward the continental shelf, and presumably formed from internal tides propagating northward from the Ilan Ridge area. A possible scenario for the formation of this wave from the internal tide is compared to related behavior south of Taiwan. On the outer continental shelf, a few large internal waves with maximum displacement greater than one-quarter of the water depth were measured with moorings. Sensors aboard ship and satellite recorded waves in this area traveling in many directions. Two possible causes (not mutually exclusive) for the multiple wave directions are scattering of nonlinear internal waves arriving from the south, and variable local generation of nonlinear gravity waves by the strong tidal and internal tidal currents. Internal tides on the shelf are relatively strong, among the strongest measured, having about 10 times greater kinetic energy density than numerous low-energy sites, which is consistent with the strong barotropic tides of the area. The ratio of diurnal baroclinic to barotropic kinetic energy found in this area is unusually high.Funding for the use of RV OR1 was provided by the National Science Council of

The flux of the lens can be separated from that of the source, companions to the source, and unrelated nearby stars with high-resolution images taken when the lens and source are spatially resolved. For typical ground-based adaptive optics (AO) or space-based observations, this requires either inordinately long time baselines or high relative proper motions. We provide a list of microlensing events toward the Galactic bulge with high relative lens-source proper motion that are therefore good candidates for constraining the lens mass with future high-resolution imaging. We investigate all events from 2004 to 2013 that display detectable finite-source effects, a feature that allows us to measure the proper motion. In total, we present 20 events with μ ≥ 8 mas yr–1. Of these, 14 were culled from previous analyses while 6 are new, including OGLE-2004-BLG-368, MOA-2005-BLG-36, OGLE-2012-BLG-0211, OGLE-2012-BLG-0456, MOA-2012-BLG-532, and MOA-2013-BLG-029. In ≤12 yr from the time of each event the lens and source of each event will be sufficiently separated for ground-based telescopes with AO systems or space telescopes to resolve each component and further characterize the lens system. Furthermore, for the most recent events, comparison of the lens flux estimates from images taken immediately to those estimated from images taken when the lens and source are resolved can be used to empirically check the robustness of the single-epoch method currently being used to estimate lens masses for many events.Peer reviewe
