Toward a computational theory for motion understanding: The expert animators model

Artificial intelligence researchers claim to understand some aspect of human intelligence when their model is able to emulate it. In the context of computer graphics, the ability to go from motion representation to convincing animation should accordingly be treated not simply as a trick for computer graphics programmers but as important epistemological and methodological goal. In this paper we investigate a unifying model for animating a group of articulated bodies such as humans and robots in a three-dimensional environment. The proposed model is considered in the framework of knowledge representation and processing, with special reference to motion knowledge. The model is meant to help setting the basis for a computational theory for motion understanding applied to articulated bodies

SyZyGy: A Straight Interferometric Spacecraft System for Gravity Wave Observations

We apply TDI, unfolding the general triangular configuration, to the special case of a linear array of three spacecraft. We show that such an array ("SyZyGy") has, compared with an equilateral triangle GW detector of the same scale, degraded (but non-zero) sensitivity at low-frequencies (f<<c/(arrany size)) but similar peak and high-frequency sensitivities to GWs. Sensitivity curves are presented for SyZyGys having various arm-lengths. A number of technical simplifications result from the linear configuration. These include only one faceted (e.g., cubical) proof mass per spacecraft, intra-spacecraft laser metrology needed only at the central spacecraft, placement in a single appropriate orbit can reduce Doppler drifts so that no laser beam modulation is required for ultra-stable oscillator noise calibration, and little or no time-dependent articulation of the telescopes to maintain pointing. Because SyZyGy's sensitivity falls off more sharply at low frequency than that of an equilateral triangular array, it may be more useful for GW observations in the band between those of ground-based interferometers (10-2000 Hz) and LISA (.1 mHz-.1 Hz). A SyZyGy with ~1 light- second scale could, for the same instrumental assumptions as LISA, make obseervations in this intermediate frequency GW band with 5 sigma sensitivity to sinusoidal waves of ~2.5 x 10^-23 in a year's integration.Comment: 13 pages, 6 figures; typos corrected, figure modified, references adde

Aspects of Gravitational and Cosmological Scattering Amplitudes

This thesis presents three distinct aspects of scattering amplitudes research along with background material on the concepts underpinning them. The first of these is the study of on-shell diagrams for \cN=7 supergravity and an associated recursion relation automatically encorporating the bonus relations. This is used to produce momentum twistor expressions which in the case of six-point NMHV use different `coordinate patches' with different ordering of external legs to get compact results and see the cancellation of spurious poles through momentum twistors. The second is the study of colour/kinematics duality of Yang-Mills amplitudes in four-dimensional Anti-de Sitter (AdS) space. By applying a generalised gauge transformation the kinematic numerators can be made to obey a Jacobi relation and these shifted numerators also obey a deformed AdS version of the Bern-Carrasco-Johansson relations. Finally we study wavefunction coefficients of scalar effective field theories (EFTs) in de Sitter space using a representation involving boundary conformal generators acting on contact diagrams and the cosmological scattering equations. Through this representation, we show that four-point wavefunction coefficients of EFTs exhibit double copy relations analogous to those in flat space with additional curvature corrections with unfixed coefficients. Imposing enhanced soft limits analogous to the EFTs in flat space allows these to be unambiguously fixed and also recovers Lagrangians with hidden shift symmetries. This is explored at four- and six-point

The Attitude of Queen Victoria Toward the Indian Mutiny and the Second Afghan War

It was in the field of foreign and imperial policy that the rights to advise, encourage, and to warn were found in wide use. The rise of the cabinet system drew the actual making of policy into its hands with the advice of parliament. Nevertheless, Gladstone pointed out that the power of the crown was of great importance in the conduct of government

A Survey of Errors in Senior Grammar at the Lincoln High School, Dallas, Texas

The use of good grammar is as habit forming as poor usage. The errors in English, which is the basic tool for all subjects, are far too frequent. The purpose of this thesis is to determine how well these students recognize these errors on this test. This entire survey is devoted to a study made of errors in senior grammar at the Lincoln High School, Dallas, Texas. The survey is made in the hope of improving these conditions in the English department at Lincoln. Every effort is made to find out as many of the causes for these conditions as possible. First, a check is made on the student to find out how they rate in comparison with students in other schools. Since it was not possible to make tests in enough schools to give a satisfactory conclusion, a reliable standard test had to be selected for that purpose. It was not possible to give the test to the entire student body or the entire senior class. A representative number of seniors in two classes were used to conduct this survey, sixty to be exact. The supervisor deemed this necessary. The Cross English test was selected by the supervisor, as it was accepted by the Dallas Board of Education as a reliable test. The Cross English test proved most satisfactory, as it dealt with the more common errors of grammar. This study will tell how these classes were organized, supervised, the method used in teaching, and administering the test. After the explanation of the frequency item in each test, the actual material used to improve the students ability is given. This material was taken from the daily lesson plan used during the survey

Five year mortality and direct costs of care for people with diabetic foot complications are comparable to cancer.

BackgroundIn 2007, we reported a summary of data comparing diabetic foot complications to cancer. The purpose of this brief report was to refresh this with the best available data as they currently exist. Since that time, more reports have emerged both on cancer mortality and mortality associated with diabetic foot ulcer (DFU), Charcot arthropathy, and diabetes-associated lower extremity amputation.MethodsWe collected data reporting 5-year mortality from studies published following 2007 and calculated a pooled mean. We evaluated data from DFU, Charcot arthropathy and lower extremity amputation. We dichotomized high and low amputation as proximal and distal to the ankle, respectively. This was compared with cancer mortality as reported by the American Cancer Society and the National Cancer Institute.ResultsFive year mortality for Charcot, DFU, minor and major amputations were 29.0, 30.5, 46.2 and 56.6%, respectively. This is compared to 9.0% for breast cancer and 80.0% for lung cancer. 5 year pooled mortality for all reported cancer was 31.0%. Direct costs of care for diabetes in general was $237 billion in 2017. This is compared to$80 billion for cancer in 2015. As up to one-third of the direct costs of care for diabetes may be attributed to the lower extremity, these are also readily comparable.ConclusionDiabetic lower extremity complications remain enormously burdensome. Most notably, DFU and LEA appear to be more than just a marker of poor health. They are independent risk factors associated with premature death. While advances continue to improve outcomes of care for people with DFU and amputation, efforts should be directed at primary prevention as well as those for patients in diabetic foot ulcer remission to maximize ulcer-free, hospital-free and activity-rich days
