Humanoid robotics is an emerging research field that has received significant attention during the past years and will continue to play an important role in robotics research and many applications of the 21st century and beyond. In this rapid moving world, there is a need of robot such a “A Human Following Robot” that can interact and co-exist with them. Because of its human following capability, these robots can work as assistants for humans in various situations and it can also acquire or monitor certain information associated with the human subject. In this paper we present a prototype that uses Arduino Uno along with basic sensors such as ultrasonic and IR sensor. All the processing is carried out by the microprocessor while the control of the motors is carried out by the controller. This robot can further be modified by using many technologies such as Bluetooth, PixyCamera etc.

Main Ideas

Abstract In his meticulously researched and conceptually innovative book, Zoltán Boldizsár Simon aims to capture the historical sensibility emergent during the postwar period broadly conceived, spanning from the 1940s to our present moment. Attending particularly to the debates concerning ecological and technological outlooks, Simon theorizes that our historical horizon is increasingly shaped by the expectations of an unprecedented event that challenges the sustainability of the human subject as known today. Arguing that the concept of unprecedented change can best be explained against the backdrop of a modern processual temporal configuration originating in the eighteenth century, Simon likewise probes the same concept to illuminate a distinct relationship with the past. Elaborating on the main ideas of the book, the paper will interrogate critically Simon’s assertion whereby the novel postwar temporality is inherently dystopian, and will negotiate Simon’s engagement with presentism, which he questions as an inaccurate representation of our current regime of historicity.

Road Maps

This is an introduction to the essays from the Jcom commentary devoted to the statute and the future of research in science communication. The authors have a long experience in international research in this domain. In the past few years, they have all been committed to the production of collective works which are now the most important references for science communication research programmes in the next few years. What topics should science communication research focus on and why? What is its general purpose? What is its real degree of autonomy from other similar fields of study? In other words, is science communication its 'own' field? These are some of the questions addressed by the in-depth discussion in this Jcom issue, with the awareness that science communication is a young, brittle research field, looking for a shared map, but also one of the most stimulating places of the contemporary academic panorama.

The Way

At a time when the Union between Scotland and England is once again under the spotlight, Remembering the Past in Nineteenth-Century Scotland examines the way in which Scotland’s national heroes were once remembered as champions of both Scottish and British patriotism. Whereas 19th-century Scotland is popularly depicted as a mire of sentimental Jacobitism and kow-towing unionism, this book shows how Scotland’s national heroes were once the embodiment of a consistent, expressive and robust view of Scottish nationality. Whether celebrating the legacy of William Wallace and Robert Bruce, the reformer John Knox, the Covenanters, 19th-century Scots rooted their national heroes in a Presbyterian and unionist view of Scotland’s past. Examined through the prism of commemoration, this book uncovers collective memories of Scotland’s past entirely opposed to 21st-century assumptions of medieval proto-nationalism and Calvinist misery. Detailed studies of 19th-century commemoration of Scotland’s national heroes Uncovers an all but forgotten interpretation of these ‘great Scots’ Shines a new light on the mindset of nineteenth-century Scottish national identity as being comfortably Scottish and British Overturns the prevailing view of Victorian Scottishness as parochial, sentimental tartanry

Significant Attention

For the past few decades, the mechanisms of immune responses to cancer have been exploited extensively and significant attention has been given into utilizing the therapeutic potential of the immune system. Cancer immunotherapy has been established as a promising innovative treatment for many forms of cancer. Immunotherapy has gained its prominence through various strategies, including cancer vaccines, monoclonal antibodies (mAbs), adoptive T cell cancer therapy, and immune checkpoint therapy. However, the full potential of cancer immunotherapy is yet to be attained. Recent studies have identified the use of bioinformatics tools as a viable option to help transform the treatment paradigm of several tumors by providing a therapeutically efficient method of cataloging, predicting and selecting immunotherapeutic targets, which are known bottlenecks in the application of immunotherapy. Herein, we gave an insightful overview of the types of immunotherapy techniques used currently, their mechanisms of action, and discussed some bioinformatics tools and databases applied in the immunotherapy of cancer. This review also provides some future perspectives in the use of bioinformatics tools for immunotherapy.

Background:A wide variety of biological activities are exhibited by N, O and S containing heterocycles and recently, many reports appeared for the synthesis of these heterocycles. The synthesis of heterocycles with the help of metal and non-metal catalyst has become a highly rewarding and important method in organic synthesis. This review article concentrated on the synthesis of S-heterocylces in the presence of metal and non-metal catalyst. The synthesis of five-membered S-heterocycles is described here.Objective:There is a need for the development of rapid, efficient and versatile strategy for the synthesis of heterocyclic rings. Metal, non-metal and organocatalysis involving methods have gained prominence because traditional conditions have disadvantages such as long reaction times, harsh conditions and limited substrate scope.Conclusion:The metal-, non-metal-, and organocatalyst assisted organic synthesis is a highly dynamic research field. For ßthe chemoselective and efficient synthesis of heterocyclic molecules, this protocol has emerged as a powerful route. Various methodologies in the past few years have been pointed out to pursue more sustainable, efficient and environmentally benign procedures and products. Among these processes, the development of new protocols (catalysis), which avoided the use of toxic reagents, are the focus of intense research.

The Past

ABSTRACT This response to the recent contribution by Matthews (2019) entitled “The Past, Present, and Future of Accounting History” specifically deals with the issues associated with concentrating on counting publication numbers in examining the state of a scholarly research field at the start of the 2020s. It outlines several pitfalls with the narrowly focused publications count analysis, in selected English language journals only, as provided by Matthews. The commentary is based on three key arguments: (1) accounting history research and publication is far more than a “numbers game”; (2) trends in the quality of the research undertaken and published are paramount; and (3) international publication and accumulated knowledge in accounting history are indeed more than a collection of English language publications. The author seeks to contribute to discussion and debate between accounting historians and other researchers for the benefit and development of the international accounting history community and global society.

Machine Interaction

Electric power wheelchairs (EPWs) enhance the mobility capability of the elderly and the disabled, while the human-machine interaction (HMI) determines how well the human intention will be precisely delivered and how human-machine system cooperation will be efficiently conducted. A bibliometric quantitative analysis of 1154 publications related to this research field, published between 1998 and 2020, was conducted. We identified the development status, contributors, hot topics, and potential future research directions of this field. We believe that the combination of intelligence and humanization of an EPW HMI system based on human-machine collaboration is an emerging trend in EPW HMI methodology research. Particular attention should be paid to evaluating the applicability and benefits of the EPW HMI methodology for the users, as well as how much it contributes to society. This study offers researchers a comprehensive understanding of EPW HMI studies in the past 22 years and latest trends from the evolutionary footprints and forward-thinking insights regarding future research.

The 40th Anniversary Edition of Taylor, Walton and Young’s New Criminology, published in 2013, opened with these words: ‘The New Criminology was written at a particular time and place, it was a product of 1968 and its aftermath; a world turned upside down’. We are at a similar moment today. Several developments have been, and are turning, our 21st century world upside down. Among the most profound has been the emergence of a new earth, that the ‘Anthropocene’ references, and ‘cyberspace’, a term first used in the 1960s, which James Lovelock has recently termed a ‘Novacene’, a world that includes both human and artificial intelligences. We live today on an earth that is proving to be very different to the Holocene earth, our home for the past 12,000 years. To appreciate the Novacene one need only think of our ‘smart’ phones. This world constitutes a novel domain of existence that Castells has conceived of as a terrain of ‘material arrangements that allow for simultaneity of social practices without territorial contiguity’ – a world of sprawling material infrastructures, that has enabled a ‘space of flows’, through which massive amounts of information travel. Like the Anthropocene, the Novacene has brought with it novel ‘harmscapes’, for example, attacks on energy systems. In this paper, we consider how criminology has responded to these harmscapes brought on by these new worlds. We identify ‘lines of flight’ that are emerging, as these challenges are being met by criminological thinkers who are developing the conceptual trajectories that are shaping 21st century criminologies.

Over the past several decades, photopolymerization has become an active research field, and the ongoing efforts to develop new photoinitiating systems are supported by the different applications in which this polymerization technique is involved—including dentistry, 3D and 4D printing, adhesives, and laser writing. In the search for new structures, bis-chalcones that combine two chalcones’ moieties within a unique structure were determined as being promising photosensitizers to initiate both the free-radical polymerization of acrylates and the cationic polymerization of epoxides. In this review, an overview of the different bis-chalcones reported to date is provided. Parallel to the mechanistic investigations aiming at elucidating the polymerization mechanisms, bis-chalcones-based photoinitiating systems were used for different applications, which are detailed in this review.

The past few decades have seen an increase of sport mega events (SMEs) held outside the Global North. This tendency has been accompanied by a growing public expenditure in these events. This paper employs selected Global South SMEs to discuss this trend. By critically analysing public documents, biddings and reports, the study traces comparisons between 21st-century Global South and Global North SMEs expenditures, in the revenue of franchise owners (FIFA and the International Olympic Committee), in construction costs within the budgets and in the costs related to security. This comprehensive and intertwined investigation shows the need for new analytical tools – such as the Renewed Policy of Sport Mega Events Allocation, a concept developed here - to better capture the central questions posed by the challenges of ‘SMEs going South’.
