Benefits of surface textures for improving the performance behaviors of tribo-contacts are being explored and established by the investigators across the globe. But the consolidated information of findings of such explorations are spread. Therefore, the objective of this paper is to summarize the information available related to the preparation of surface textures and performance outcomes in the presence of surface textures at the concentrated contacts. Mainly, recent research findings and practices followed for the study of friction, wear, lubrication, contact fatigue, vibration, and noise at the generic concentrated contacts in presence of surface textures are reviewed for current status of research in the area and outlining the future prospects.

In July 2012 the ATLAS and CMS experiments announced the discovery of a Higgs boson, confirming the conjecture put forward by Tom Kibble and others in the 1960s. This article will attempt to outline some of the challenges faced during the construction of the Large Hadron Collider and its experiments, their operation and performance, and selected physics results. In particular, results relating to the new heavy boson will be discussed as well as its properties and the future prospects for the LHC programme.

Abstract Nontyphoidal Salmonella and Salmonella Paratyphi are responsible for significant morbidity and mortality worldwide. To date, no vaccine has been licensed against these organisms. The development of effective vaccines remains an urgent priority. In this review, the rationale for and current status of various vaccine candidates against S. Paratyphi and nontyphoidal Salmonella are presented, with a focus on the research findings from the 2019 International Conference on Typhoid and Other Invasive Salmonelloses. Additionally, other vaccine candidates that are currently undergoing clinical development are highlighted. Future approaches, which may include antigens that are genetically conserved across Salmonella and confer broad, non–serotype-specific protection, are also discussed.

Botnets have been around for about three decades, and their sophistication and capabilities have evolved rapidly over the period. Originally simple codes that were used for the administration of IRC channels, botnets today pose very formidable threats to systems and network infrastructure. They have become one of the more-preferred options in the toolkit of hackers and cybercriminals; particularly due to their ability to subvert and overrun secure infrastructures within a relatively short time. Research has greatly advanced in trying to keep up with the rapid evolution of the botnet threat. At this time, it is important to review the status of the threat, vis-á-vis the extent of research that has emerged in relation to the threat. This is crucial for understanding the future prospects of the threat, in terms of where it is headed next; as well as what research areas require more work. This exploratory research serves this purpose. It introduces the botnet threat from its early origins; then it traverses the current status of botnets, and summarizes research efforts so far (highlighting some limitations of modern countermeasures). It further goes on to discuss the future trends of botnets and botnet research, before bringing it together to present the current threat landscape.

Approximately ten years ago the first experiments were performed in which the Auger electrons produced after inner-shell ionisation of atoms by electron impact were detected in coincidence with the scattered electrons. Only a limited number of such experiments have been performed since that time, mainly due to the very low count rates characteristic of these measurements. Recent developments in the field are discussed and the future prospects for such measurements are considered.
