Metrical Distinctiveness of Indian Crania Demonstrated through Stepwise Multivariate Classification
Our previous metrical study of Indian crania from across the South Asian subcontinent found great variability within all of the series, combined with average trends whereby the Indian series resemble each other and contrast with series outside of South Asia. This contribution confirms the craniometric distinctiveness of Indian crania, notwithstanding their intra-series variability, through stepwise discriminant function analysis of the six best sampled series from northern and South India. The proportion of crania from places beyond South Asia classified as Indian is negligible, while over 90% of Indian crania are correctly identified as Indian. This correct identification of Indian crania is enhanced amongst those specimens whose possession of pronouncedly Indian craniometric attributes is revealed through index analysis. By extrapolation, index analysis may also assist the correct classification of non-Indian populations that also are craniometrically distinct. Further, Indians’ craniometric distinctiveness aligns with genetic evidence for the predominantly indigenous ancestry of Indians who speak Indo-Aryan and especially Dravidian languages
Effect of soil parameter uncertainty on seismic response of buried segmented pipeline
Pipelines are important lifeline facilities spread over a large area and they generally encounter a range of seismic hazards and different soil conditions. The seismic response of a buried segmented pipe depends on various parameters such as the type of buried pipe material and joints, end restraint conditions, soil characteristics, burial depths, and earthquake ground motion, etc. This study highlights the effect of the variation of geotechnical properties of the surrounding soil on seismic response of a buried pipeline. The variations of the properties of the surrounding soil along the pipe are described by sampling them from predefined probability distribution. The soil-pipe interaction model is developed in OpenSEES. Nonlinear earthquake time-history analysis is performed to study the effect of soil parameters variability on the response of pipeline. Based on the results, it is found that uncertainty in soil parameters may result in significant response variability of the pipeline

Impact of tissue microstructure on a model of cardiac electromechanics based on MRI data
Cardiac motion is a vital process as it sustains the pumping of blood in the body. For this reason motion abnormalities are often associated with severe cardiac pathologies. Clinical imaging techniques, such as MRI, are powerful in assessing motion abnormalities but their connection with pathology often remains unknown.

Computational models of cardiac motion, integrating imaging data, would thus be of great help in linking tissue structure (i.e. cells organisation into fibres and sheets) to motion abnormalities and to pathology. Current models, though, are not able yet to correctly predict realistic cardiac motion in the healthy or diseased heart.

Our hypothesis is that a more realistic description of tissue structure within an electromechanical model of the heart, with structural information extracted from data rather than mathematically defined, and a more careful definition of tissue material properties, would better represent the high heterogeneity of cardiac tissue, thus improving the predictive power of the model
A Comparison of Numerical Methods used for\ud Finite Element Modelling of Soft Tissue\ud Deformation
Soft tissue deformation is often modelled using incompressible nonlinear elasticity, with solutions computed using the finite element method. There are a range of options available when using the finite element method, in particular, the polynomial degree of the basis functions used for interpolating position and pressure, and the type of element making up the mesh. We investigate the effect of these choices on the accuracy of the computed solution, using a selection of model problems motivated by typical deformations seen in soft tissue modelling. We set up model problems with discontinuous material properties (as is the case for the breast), steeply changing gradients in the body force (as found in contracting cardiac tissue), and discontinuous first derivatives in the solution at the boundary, caused by a discontinuous applied force (as in the breast during mammography). We find that the choice of pressure basis functions are vital in the presence of a material interface, higher-order schemes do not perform as well as may be expected when there are sharp gradients, and in general that it is important to take the expected regularity of the solution into account when choosing a numerical scheme
The poisson process in quantum stochastic calculus
Given a compensated Poisson process based on , the Wiener-Poisson isomorphism is constructed. We restrict the isomorphism to and prove some novel properties of the Poisson exponentials . A new proof of the result is also given. The analogous results for are briefly mentioned.
The concept of a compensated Poisson process over is generalised to any measure space as an isometry satisfying certain properties. For such a generalised Poisson process we recall the construction of the generalised Wiener-Poisson isomorphism, , using Charlier polynomials. Two alternative constructions of are also provided, the first using exponential vectors and then deducing the connection with Charlier polynomials, and the second using the theory of reproducing kernel Hilbert spaces.
Given any measure space , we construct a canonical generalised Poisson process , where is the maximal ideal space, with the completion of its Borel -field with respect to , of a -algebra . The Gelfand transform is unitarily implemented by the Wiener-Poisson isomorphism . This construction only uses operator algebra theory and makes no a priori use of Poisson measures.
A new Fock space proof of the quantum Ito formula for is given. If is a real, bounded, predictable process with respect to a compensated Poisson process , we show that if , then on , and that is an essentially self-adjoint quantum semimartingale. We prove, using the classical Ito formula, that if is a regular self-adjoint quantum semimartingale, then is an essentially self-adjoint quantum semimartingale satisfying the quantum Duhamel formula, and hence the quantum Ito formula. The equivalent result for the sum of a Brownian and Poisson martingale, provided that the sum is essentially self-adjoint with core , is also proved
Cyberlaw : A Study On The Computer Crime Act
The world of information technology is growing tremendously. More and more computer users surf the cyberspace everyday. Advancement in communication
technology enables the usage of Internet in various aspects of our daily live. Cyberspace is a space without boundary, law enforcement and virtual. Computers are
used as a medium to surf this space with Internet technology. Various activities ranging from business, education, government ruling and others uses Internet. The
wide usage of Internet imposes a new problem, computer crime. The law enforcement for computer crimes is categorized as Cyber Law. This is a very specific law to prevent unlawful activities involving the usage of computers. Cyber Law should be amended frequently along with the growth of Internet technology. This law has to be comprehensive. The definition used has to be precise
to avoid any confusion. The definition analysis on computer crime act has to be conducted regularly. This is to ensure latest definition in the world of information
technology is updated on a timely manner. Computer crimes can be prevented using prevention steps. These steps will help to curb these crimes
The Myth of Preliminary Due Process for Misdemeanor Prosecutions in New York
The existing criminal procedure laws of New York do not afford the misdemeanor accused any meaningful preliminary opportunity to fight the substantiation of the accusations against them. This is problematic given that a criminal prosecution can have extreme consequences on an individual’s life, including the loss of liberty, employment, housing, child custody or freedom from immigration removal proceedings. This article therefore analyzes the weaknesses in the existing criminal procedure laws for these prosecutions, and assesses how historical protections dissolved into the myth of preliminary due process for misdemeanor cases today. Ultimately, since the current procedures are ineffective in protecting against unwarranted misdemeanor prosecutions, the solution lies in reintroducing preliminary hearings in all misdemeanor prosecutions to better provide due process for all in the State of New York
