On the Term Structure of Futures and Forward Prices

We investigate the term structure of forward and futures prices for models where the price processes are allowed to be driven by a general marked point process as well as by a multidimensional Wiener process. Within an infinite dimensional HJM-type model for futures and forwards we study the properties of futures and forward convenience yield rates. For finite dimensional factor models, we develop a theory of affine term structures, which is shown to include almost all previously known models. We also derive two general pricing formulas for futures options. Finally we present an easily applicable sufficient condition for the possibility of fitting a finite dimensional futures price model to an arbitrary initial futures price curve, by introducing a time dependent function in the drift term.term structure; futures price; forward price; options; jump-diffusion model; affine term structure

Survey of Branch Prediction, Pipelining, Memory Systems as Related to Computer Architecture

This paper is a survey of topics introduced in Computer Engineering Course CEC470: Computer Architecture (CEC470). The topics covered in this paper provide much more depth than what was provided in CEC470, in addition to exploring new concepts not touched on in the course. Topics presented include branch prediction, pipelining, registers, memory, and the operating system, as well as some general design considerations for computer architecture as a whole. The design considerations explored include a discussion on different types of instruction types specific to the ARM Instruction Set Architecture, known as ARM and Thumb, as well as an exploration of the differences between heterogeneous and homogeneous multi-processors. Further sections explain the interoperability of various portions of the computer architecture with a focus on performance optimizations. Branch prediction is introduced, and the quality improvement which branch prediction provides is detailed. An explanation of pipelining is given followed by how pipelining on different types of processors may be difficult. Registers, one of the fundamental parts of a computer, are explained in detail, as well as their importance to computer systems as a whole. The memory and operating systems sections tie this paper together by delving deeper into the architecture of computers, then resurfacing with how the software and hardware interact through the operating system. This paper concludes by tying each section discussed together and presenting the importance of computer architecture

Touchy Topics: The Imperial Public Anxiety and Null Curriculum of Sexuality in Late Nineteenth- and Early Twentieth-Century Britain

At the height of British imperial power and global influence in the late nineteenth- and early twentieth century, Britain’s populace and intellectuals alike frequently saw one fitting comparison in patriotically describing their Empire: the might of Britain, in their eyes, resembled that of the Roman Empire. To the dismay of many, however, such a comparison extended not only to Rome’s dominance but its demise as well. The fall of Rome was described in Britain as being the result of moral degradation, paralyzing the Empire from within. With the rise of social Darwinism, moreover, the strength of the British Empire, like that of Rome, soon came to be associated with the strength of the individuals that comprised the state. While troops fought for Queen and Country abroad, an alternative frontline of childhood sexual deviance, in the eyes of many, threatened the British Empire internally. An examination of the actions and policies of the perceived soldiers of this frontline, teachers and headmasters, is attempted here through the theoretical lens of null curriculum. Null curriculum signifies not what is taught publicly, but rather expressed and learned through absence. Despite public calls to arms against male sexuality in the speeches, publications, letters and policy documents of teachers and headmasters, the sexual regulation of boys in public schools was seemingly silent and largely reserved to the null curriculum

Why, If Things Are So Good, Are They So Bad? Magnitogorsk, Stalin’s Five-Year Plan, and American Engineers, 1928–1932

This article focuses on Magnitogorsk, the Magnetic Mountain, the practical and symbolic crux of Stalin’s Five-Year Plan. To Stalin, the Magnetic Mountain and the instant industrial city of Magnitogorsk would help materialize the radical dream of the Soviet Union and eventually save it from invaders from the west. American involvement in early Soviet technological expansion has been historically hidden and ignored by American’s and Soviet’s alike. This article argues that while Stalin called for industrial expansion to outstrip the West, paradoxically it was Western engineers that made his progress possible

High Resolution Validation of Next Generation Turbulent Flow Models Using Neutron Beams, Laser Fluorescence, and Cryogenic Helium

Turbulent fluid flow is an incredibly unpredictable subject that continues to confound scientists and engineers. All of the empirical data that has been the basis of conventional turbulent computational fluid dynamics (CFD) models for decades only extends to roughly the equivalent turbulence created when Michael Phelps swims in a pool. The problem is that this data is then extrapolated out many orders of magnitude in order to design cruise ships, airplanes, and rockets which operate in significantly more turbulent flow regimes. This creates an incredible degree of uncertainty in the design process that demands over-engineering and increased expenditures. The development of a new technique that allows scientists to capture high resolution flow data for extremely turbulent conditions as a function of three-dimensional space and time could revolutionize the aerospace industry. A proof of principle experiment has been developed that utilizes the unique properties of superfluid cryogenic helium and metastable helium-2 excimers to directly image turbulent flow on the scale of tens of microns. By scaling this technique up, a new generation of turbulent flow models will be created for the modern age

Growth Differentiation Factor 5 is a Paracrine Regulator of Sarcopenic Obesity

Sarcopenic obesity attributes to skeletal muscle loss more than sarcopenia and obesity alone. Individuals with SO suffer from the comorbidity of excess body fat and concurrent muscle mass loss due to aging. Growth differentiation factors (Gdfs) have never been recognized as playing a role in skeletal muscle maintenance in those with SO. Specifically, Gdf5, has been recognized as playing a part in Bone Morphogenic Protein signaling to activate protein synthesis and deactivate protein degradation via SMAD 1/5/8 and SMAD 4 complex. Using RNA sequencing, Gdf5 was identified as being significantly upregulated in SO mice. Purpose: To determine the cellular role that Gdf5 plays in sarcopenic obese skeletal muscle. Methods: In vitro experimentation was conducted by using C2C12 cell culture. Cells were grown to 70-80% confluency with 10% growth media and differentiated out for 6 days in differentiation media. Lipofectamine transfection was used to transfect myoblasts with an empty vector control plasmid or a shRNA for Gdf5 knockdown. Western blot was used to measure Gdf5 protein expression. Myotube diameter were measured for each group. Markers for myogenic regulation (Cyclin D1, MyoD, MyoG), protein degradation (Atrogin, MuRF1) and inflammatory markers (IL-6, TNF-α) were assessed using RT-PCR for mRNA abundance. Results: There was a 62% and 30% (p\u3c0.05) decrease of Gdf5 protein expression at 28 kDa and 55 kDa in the shRNA 1 group. The shRNA 2 and 3 groups had decreases of 36% and 27% (p\u3c0.05) at 55 kDa. respectively. Myotube size between groups were unchanged. Gdf5 and Dnmt3a mRNA abundance increased in the Gdf5 shRNA group when compared to control group by 51% and 14% (p\u3c0.05) respectively. In the Gdf5 shRNA group, mRNA abundance of MyoD was decreased by 17% and MyoG was increased by 51% (p\u3c0.05). mRNA abundance of protein degradation marker, MuRF-1, was increased by 39.2% (p\u3c0.05) in the Gdf5 shRNA group
