Hawking Radiation of an Arbitrarily Accelerating Kinnersley Black Hole: Spin-Acceleration Coupling Effect

The Hawking radiation of Weyl neutrinos in an arbitrarily accelerating Kinnersley black hole is investigated by using a method of the generalized tortoise coordinate transformation. Both the location and temperature of the event horizon depend on the time and on the angles. They coincide with previous results, but the thermal radiation spectrum of massless spinor particles displays a kind of spin-acceleration coupling effect.Comment: 8 pages, no figure, revtex 4.0, revisted version with typesetting errors and misprint correcte

Conditional Local Convolution for Spatio-temporal Meteorological Forecasting

Spatio-temporal forecasting is challenging attributing to the high nonlinearity in temporal dynamics as well as complex location-characterized patterns in spatial domains, especially in fields like weather forecasting. Graph convolutions are usually used for modeling the spatial dependency in meteorology to handle the irregular distribution of sensors' spatial location. In this work, a novel graph-based convolution for imitating the meteorological flows is proposed to capture the local spatial patterns. Based on the assumption of smoothness of location-characterized patterns, we propose conditional local convolution whose shared kernel on nodes' local space is approximated by feedforward networks, with local representations of coordinate obtained by horizon maps into cylindrical-tangent space as its input. The established united standard of local coordinate system preserves the orientation on geography. We further propose the distance and orientation scaling terms to reduce the impacts of irregular spatial distribution. The convolution is embedded in a Recurrent Neural Network architecture to model the temporal dynamics, leading to the Conditional Local Convolution Recurrent Network (CLCRN). Our model is evaluated on real-world weather benchmark datasets, achieving state-of-the-art performance with obvious improvements. We conduct further analysis on local pattern visualization, model's framework choice, advantages of horizon maps and etc.Comment: 14 page

Montana’s Campaign Contribution Limits Put to the Test in \u3cem\u3eLair v. Bullock\u3c/em\u3e

Montana’s campaign contribution limits directly address the anti-corruption state interest. While the minimum standard for corruption applied in Eddleman was much broader, the facts of that case also meet the definition of quid pro quo corruption or its appearance. Even if the contribution limits were originally conceived to prohibit a broader range of activity, they are still sufficiently tailored to pass muster under the narrower Citizens United standard. Montana’s long history of combatting corruption demonstrates that there is a compelling state interest. Montana’s contribution limits are also closely drawn to that anticorruption interest. There is a freedom to affiliate that has been unchanged since Eddleman was decided. While Montana’s individual contribution limits are low by national standards, candidates still are capable of amassing sufficient resources to mount effective campaigns. Under an Eddleman analysis, the contribution limits are not so stifling as to render campaigns ineffective. Montanans wanted low contribution limits specifically to combat the type of quid pro quo corruption experienced in the age of the Copper Kings by requiring candidates to obtain broad-based contribution support. The limits are narrowly tailored given Montana’s history of political corruption. Because Montana has a compelling state interest and its campaign contribution limits are narrowly tailored to that interest, the limits should be upheld in the next hearing before the district court

Valuing Domestic Work

This report is based on a three-year collaboration with Domestic Workers United (DWU) and the National Domestic Workers Alliance (NDWA). BCRW was proud to host the first National Domestic Workers Alliance congress at Barnard College in 2008 and subsequently the first East Coast Regional Congress in 2009. Together BCRW, DWU, and NDWA developed this publication in order to further knowledge about the processes by which domestic work has been devalued historically and how we can all work together to make domestic work safe, fair, and protected

Water resources assessment, irrigation and agricultural developments in Tajikistan

This paper provides a description of current state of water resources assessment in Tajikistan, their use for the agriculture development and maintenance of irrigation infrastructures. The Vakhsh and Pyandzh River Basins and its tributaries in Tajikistan were directly surveyed during an expedition within the framework of a Joint Research Project: Investigation of natural resources of Central Asia and reconstruction of agriculture in Afghanistan, that is supported by the Ministry of Education and Culture of Japan Grant in Aid for Scientific Joint Research, 2003, No. 15252002), that is represented by professor Dr. Tsuneo Tsukatani, Department of Natural Resources and the Environment, Kyoto Institute of Economics, Kyoto University, Japan. The field expedition was carried out in September 2003 according to the Joint Project Research Program to study the natural resources and contemporary state of irrigation in Pyandzh River basin.water resources, cropping system, irrigation infrastructure, Tajikistan, Subsurface drip irrigation, SDI, Pyandzh, AmuDarya, Kumsangir, Vakhsh
