A Computational Study of Icart\u27s Function

A hash function maps some elements of a larger, initial set to elements of a smaller, resultant set. By nature, this leads to collisions and, sometimes, not all elements in the smaller set will be mapped to as a result. The set in consideration here is all points on an elliptic curve. This is a special class of curve with two variables, which takes the form here as y2 = x3 + ax + b. A hash function is useful in offering a deterministic way to map an input to a pair of x and y values that satisfy such an equation. This paper experimentally verifies that an asymptotic result on the size of the image for Icart\u27s hash function provided by Fouque and Tibouchi is true for small primes less than 219 and for all curves of conductor less than or equal to 100. Combined with Fouque and Tibouchi\u27s asymptotic result, this proves that the coverage of Icart\u27s hash function is a 5/8 fraction of the points (with some error)

Characterization of Hardening by Design Techniques on Commercial, Small Feature Sized Field-Programmable Gate Arrays

In this thesis, a methodology is developed to experimentally test and evaluate a programmable logic device unde r gamma irradiation. The purpose of which is to determine the radiation effects and characterize the improvements of various hardening by design techniques. The techniques analyzed in this thesis include Error Correction Coding (ECC) and Triple Modular Redundancy (TMR). The TMR circuit includes three different functional implementations of adders compared to TMR voted circuits of those same adders. The TMR is implemented with the same functional adders and as a Functional TMR (FTMR) with three different function adders that are voted on. The three functional adders are: a behavioral adder that allows the FPGA synthesis software to create the implementation, a ripple carry adder that consists of multiple single bit full adders linked together, and a carry look ahead adder that operates the fastest by using an algorithm that creates generate and propagate signals. These adders are connected to single voter TMR and FTMR circuits to evaluate the improvements that could be obtained. The ECC circuit includes Block RAM (BRAM) and Distributed RAM memory elements that are loaded both with ECC and non-error corrected data. The circuit is designed to check for errors in memory data, stuck bit values in the memory, and the performance improvements that ECC provides the system

Inconceivability, Horror, and the Mercy Seat

In an ordinary home in Huron, South Dakota-sometime in the very early morning hours of Sunday, April 5, 1987-a young girl was murdered in her crib. By March of the next year, her mother, Debra Jenner, had been convicted of second-degree murder. She was sentenced to life in prison. Although she became eligible for parole in 2003 after Governor Janklow commuted her sentence, her applications for discretionary parole were consistently denied. She remained incarcerated until last year, when she was finally granted parole. This essay embarks on a retelling of Debra Jenner\u27s trial, her subsequent post-conviction proceedings, and her numerous parole hearings, including the one in which she finally won release in September of 2021. In the process, it confronts a criminal act so ghastly that it evades nearly every attempt to comprehend it and attempts to assess the proper role of mercy in the criminal justice system-specifically, in the context of applications for discretionary parole. [M]ercy is above this scepter\u27d sway. - Shakespear

A Will for Willa Cather

Consider a songwriter who wants to ban the use of her music in advertisements or an author intent on eliminating the possibility that her novel will be optioned to a filmmaker. The law frowns upon these sorts of alienability limitations and use constraints. Property – including intellectual property – comes with an assorted bundle of use and alienability rights. The law detests unreasonable restraints on alienability. Courts have deterred owners from placing use limitations on property that bind future owners. Restraints on alienation are said to be repugnant, as are future interests that vest too remotely. The dead hand is feared and the living hand is protected. Exceptions can be noted, such as short-term use limitations between contracting parties, equitable servitudes, and the nearly extinct determinable estates. These exceptions, however, are generally present either in commercial or charitable contexts. In the private noncharitable donative context, which we will be concerned in the pages that follow, use and alienability limitations are more closely scrutinized. This Article is concerned specifically with use restrictions in the private non-charitable donative context

Invasion of winter moth in New England: Effects of defoliation and site quality on tree mortality.

Abstract Widespread and prolonged defoliation by the European winter moth, Operophtera brumata L., has occurred in forests of eastern Massachusetts for more than a decade and populations of winter moth continue to invade new areas of New England. This study characterized the forests of eastern Massachusetts invaded by winter moth and related the duration of winter moth defoliation estimated using dendrochronology to observed levels of tree mortality and understory woody plant density. Quercus basal area mortality in mixed Quercus and mixed Quercus-Pinus strobus forests in eastern Massachusetts ranged from 0-30%; mortality of Quercus in these forests was related to site quality and the number of winter moth defoliation events. In addition, winter moth defoliation events lead to a subsequent increase in understory woody plant density. Our results indicate that winter moth defoliation has been an important disturbance in New England forests that may have lasting impacts

The structure of the diencephalon in the insectivora (especially elephantulus myurus), the tupaioidea and the prosimian primates, with special reference to the evolution of the primate diencephalon.

A thesis submitted to the Faculty of Science, University of the Witwatersrand, Johannesburg, for the Degree of Doctor of Philosophy.The comparative structure of the diencephalon was investigated in the elephant shrew, the tree-shrew and several of the prosimian and anthropoid primates, including man. The brains were perfused with and fixed in formol saline. Most of those brains were sectioned transversely; others horizontally and sagitaliy. Sections of the diencophalon were stained with the cresyl-echt violet method for cytology and the study of cytoarchitectonics, and with the Kluver and Barrera, and Simmons techniques for myeloarchitectonics.WHSLYP201

Ecological and evolutionary processes at expanding range margins

Many animals are regarded as relatively sedentary and specialized in marginal parts of their geographical distributions. They are expected to be slow at colonizing new habitats. Despite this, the cool margins of many species' distributions have expanded rapidly in association with recent climate warming. We examined four insect species that have expanded their geographical ranges in Britain over the past 20 years. Here we report that two butterfly species have increased the variety of habitat types that they can colonize, and that two bush cricket species show increased fractions of longer-winged (dispersive) individuals in recently founded populations. Both ecological and evolutionary processes are probably responsible for these changes. Increased habitat breadth and dispersal tendencies have resulted in about 3- to 15-fold increases in expansion rates, allowing these insects to cross habitat disjunctions that would have represented major or complete barriers to dispersal before the expansions started. The emergence of dispersive phenotypes will increase the speed at which species invade new environments, and probably underlies the responses of many species to both past and future climate change
