The presence of vegetation on railway tracks threatens track safety and longevity. However, vegetation inspections in Sweden are currently being carried out manually. Manually inspecting vegetation is very slow and time consuming. Maintaining an even quality standard is also very difficult. A machine vision-based approach is therefore proposed to emulate the visual abilities of the human inspector. Work aimed at detecting vegetation on railway tracks has been split into two main phases. The first phase is aimed at detecting vegetation on (...) the tracks using appropriate image analysis techniques. The second phase is aimed at detecting the rails in the image to determine the cover of vegetation that is present between the rails as opposed to vegetation present outside the rails. Results achieved in the current work indicate that the machine vision approach has performed reasonably well in detecting the presence/absence of vegetation on railway tracks when compared with a human operator.

Spatially and temporally restricted expression of Hox genes requires multiple mechanisms at both the transcriptional and the post-transcriptional levels. New insight into this precise expression mechanism comes from recent findings of a novel sense–antisense miRNA combination from the bithorax complex of Drosophila melanogaster.1-4 These two miRNAs encoded from the same locus target 3′ untranslated regions of anterior hox genes, Antp, Ubx and abd-A to establish the dominance of posterior hox gene Abd-B in its expression domain. Such double-edge tools, sense–antisense miRNA (...) combinations, also operate at multiple loci in the genome implicating their wider impact on the post-transcriptional gene regulation in eukaryotes.

Description: Jain Philosophy : Historical Outline interprets the fundamentals of Jain philosophy from the viewpoint of their historical genesis and development and shows that the incipient stage of the Jain thought-complex agreed totally with the pythagorean approach to philosophy which was based on observed realities and was quite in harmony with the existing socio-political conditions of the time of Lord Mahavira while the sophisticated stage marked by the a priori doctrines and dogmas it had generated in course of its development (...) and by the traditionally floating ideas in regard to the belief in a eternal moral order in the universe, the law of karma, ignorance as the cause of bondage and knowledge as that of liberation, the efficacy of meditation, and so forth, was a persistent juxtaposition in the evolutionary stages of the former. Since no system of Indian philosophy allows a purely isolated treatment, a comparative study of all the philosophical systems has been made here to determine the real nature of the Jain standpoint with more emphasis on the original dynamism of Jainism which had contributed to the growth of various natural sciences, including those of biology and astronomy, on the total rejection of the concept of a supernatural agent in the form of God, on the theories of valid knowledge and on the unique logical system based on the principles of relativity.

. Speaker recognition has been an active research area for many years. Methods to represent and quantify information embedded in speech signal are termed as features of the signal. The features are obtained, modeled and stored for further reference when the system is to be tested. Decision whether to accept or reject speakers are taken based on parameters of the data modeling techniques. Real world offers various degradations to the signal that hamper the signal quality. The degradations may be due (...) to ambient background noise, reverberation or multispeaker scenario. This paper presents a survey of various feature extraction, data modeling methods, metrics that are used to take the decisions and methods that can be used to preprocess the degraded data that have been used to perform the task of speaker recognition.

On journalistic ethics of mass media in Sri Lanka and the role of Śrī Laṅkā Puvatpat Maṇḍalaya.

Serial analysis of gene expression (SAGE) is a powerful technique that can be used for global analysis of gene expression. Its chief advantage over other methods is that it does not require prior knowledge of the genes of interest and provides qualitative and quantitative data of potentially every transcribed sequence in a particular cell or tissue type. This is a technique of expression profiling, which permits simultaneous, comparative and quantitative analysis of gene‐specific, 9‐ to 13‐basepair sequences. These short sequences, called (...) SAGE tags, are linked together for efficient sequencing. The sequencing data are then analyzed to identify each gene expressed in the cell and the levels at which each gene is expressed. The main benefit of SAGE includes the digital output and the identification of novel genes. In this review, we present an outline of the method, various bioinformatics methods for data analysis and general applications of this important technology.

Thomas Kuhn's The Structure of Scientific Revolutions has sold more than one million copies since its publication in 1962, is one of the most cited academic books of all time, and continues to be read and studied today. This volume of new essays evaluates the significance of Kuhn's classic book in its changing historical context, including its initial reception and its lasting effects. The essays explore the range of ideas which Kuhn made popular with his influential philosophy of science, including (...) paradigms, normal science, paradigm changes, scientific revolutions, and incommensurability; and they also look at less-studied themes in his work, including scientific measurement, science education, and science textbooks. Drawing on the latest scholarship as well as unpublished material in the Thomas Kuhn Archives at MIT, this volume offers a comprehensive way into Kuhn's philosophy and demonstrates the continuing relevance of his ideas for our understanding of science.

Phosphatidylinositol 4,5‐bisphosphate (PI4,5P2) is a key lipid signaling molecule that regulates a vast array of biological activities. PI4,5P2 can act directly as a messenger or can be utilized as a precursor to generate other messengers: inositol trisphosphate, diacylglycerol, or phosphatidylinositol 3,4,5‐trisphosphate. PI4,5P2 interacts with hundreds of different effector proteins. The enormous diversity of PI4,5P2 effector proteins and the spatio‐temporal control of PI4,5P2 generation allow PI4,5P2 signaling to control a broad spectrum of cellular functions. PI4,5P2 is synthesized by phosphatidylinositol phosphate kinases (...) (PIPKs). The array of PIPKs in cells enables their targeting to specific subcellular compartments through interactions with targeting factors that are often PI4,5P2 effectors. These interactions are a mechanism to define spatial and temporal PI4,5P2 synthesis and the specificity of PI4,5P2 signaling. In turn, the regulation of PI4,5P2 effectors at specific cellular compartments has implications for understanding how PI4,5P2 controls cellular processes and its role in diseases. (shrink)

This paper offers a review of the catalogue composed by Myriam Vogelaar of one of the largest and most important collections of Fight Books and fencing manuals in the field of Historical European Martial Arts Studies (HEMAS). The Mokken Collection is named after Wiebe Mokken, the man who meticulously built it up over the past decades in Amsterdam. The book also highlights the glaring lack of contemporary knowlegde about other major historical fencing-related collections, like Gotti’s spectacular private collection held at (...) the Museo dell Arte Marziale in Brescia, Italy. Others, such as the Corble collection at the KU Leuven Libraries, recently published their catalogue on line. This catalogue thus constitutes an important milestone for this exciting and still relatively new subdomain in the field of European cultural studies, by making accessible one of the most important collections of source materials dedicated to it.

At the beginning of the study of physical phenomena, the idea of "force" was widely used to explain the non-stationarity of observed phenomena, such as the movement of bodies. However, as mechanics and physical theories developed, the force notions gained own formal definitions and names, without the use of the term "force". So, the concept of kinetic energy arose instead of "vis viva", and "current" instead of "current strength" ets. Additionally, a number of new physical theories have been formulated without (...) the use of force concept. As a result, different types of forces have gradually been replaced by other more important concepts, such as energy and action, which are closely linked to fundamental physical principles. It is interesting to note that the general trend in the development of civilizations has been a shift from unrestricted power (expressed in the thesis "might makes right") to its subordination and incorporation into a legal framework. This is similar to the evolution of physics, which has seen the notion of force become eliminated or subordinated to more general principles and laws. (shrink)
