History of Endoscopic Spine Surgery in India

Endoscopic spine surgeries provide distinct advantages and is therefore a viable alternative to open or microscopic techniques. Indian surgeons have shown their expertise from craniovertebral junction to lumbosacral spine with these techniques. Many novel approaches like endoscopic transcervical, partial corpectomy, and others have been designed, and many technological innovations for these surgeries have been made. With different training programs attracting both native and international surgeons, the future of endoscopic spine surgery is bright.

Novel Approaches for Species Concepts and Delimitation in Polyploids and Hybrids

Hybridization and polyploidization are important processes for plant evolution. However, classification of hybrid or polyploid species has been notoriously difficult because of the complexity of processes and different evolutionary scenarios that do not fit with classical species concepts. Polyploid complexes are formed via combinations of allopolyploidy, autopolyploidy and homoploid hybridization with persisting sexual reproduction, resulting in many discrete lineages that have been classified as species. Polyploid complexes with facultative apomixis result in complicated net-work like clusters, or rarely in agamospecies. Various case studies illustrate the problems that apply to traditional species concepts to hybrids and polyploids. Conceptual progress can be made if lineage formation is accepted as an inevitable consequence of meiotic sex, which is established already in the first eukaryotes as a DNA restoration tool. The turnaround of the viewpoint that sex forms species as lineages helps to overcome traditional thinking of species as “units”. Lineage formation and self-sustainability is the prerequisite for speciation and can also be applied to hybrids and polyploids. Species delimitation is aided by the improved recognition of lineages via various novel -omics methods, by understanding meiosis functions, and by recognizing functional phenotypes by considering morphological-physiological-ecological adaptations.

KnowMIS-ABSA: an overview and a reference model for applications of sentiment analysis and aspect-based sentiment analysis

The analysis of the opinions of customers and users has been always of great interest in supporting decision-making in many fields, especially in marketing. Sentiment analysis (SA) is the umbrella term for techniques and approaches that analyze user’s sentiments, emotions, opinions in text or other media. The need for a better understanding of these opinions paved the way to novel approaches that focus on the analysis of the sentiment related to specific features of a product, giving birth to the field of aspect-based sentiment analysis (ABSA). Although the increasing interest in this discipline, there is still confusion regarding the basic concepts of ABSA: terms like sentiment, affect, emotion, opinion, are used as synonyms while they represent different concepts. This often leads to an incorrect analysis of the users’ opinions.This work presents an overview of the state-of-the-art techniques and approaches for ABSA, highlighting the main critical issues related to current trends in this field. Following this analysis, a new reference model for SA and ABSA, namely the KnowMIS-ABSA model, is proposed. The model is grounded on the consideration that sentiment, affect, emotion and opinion are very different concepts and that it is profoundly wrong to use the same metric and the same technique to measure them. Accordingly, we argue that different tools and metrics should be adopted to measure each of the dimensions of an opinion. A qualitative case study, regarding product reviews, is proposed to motivate the advantages of the KnowMIS-ABSA model.

Flow Control in Wings and Discovery of Novel Approaches via Deep Reinforcement Learning

In this review we summarize existing trends of flow control used to improve the aerodynamic efficiency of wings. We first discuss active methods to control turbulence, starting with flat-plate geometries and building towards the more complicated flow around wings. Then, we discuss active approaches to control separation, a crucial aspect towards achieving high aerodynamic efficiency. Furthermore, we highlight methods relying on turbulence simulation, and discuss various levels of modelling. Finally, we thoroughly revise data-driven methods, their application to flow control, and focus on deep reinforcement learning (DRL). We conclude that this methodology has the potential to discover novel control strategies in complex turbulent flows of aerodynamic relevance.

Using Road Maps for High-tech Projects Management

The purpose of this article is to study the necessity of creation and road maps usage as an effective ‎tool in order to create novel approaches for managing innovative high-tech projects using the author-developed criterion of innovative ‎tension, interpreted as the difference of potentials of participants in the innovation process — the ‎donor-enterprise of innovations and the recipient-enterprise of innovations.‎ The method of comparative analysis of various forms of organization of the innovation process and the corresponding variants of the ‎ratio of innovative potentials of participating enterprises was used. As a result of the conducted research, methodical approaches to evaluate innovation potentials of donors-enterprises of innovations and enterprises-recipients of innovations were developed. A ‎criterion for estimating the innovative potential in the donor-recipient system, so-called innovative stress, is formulated. An attempt to disclose the importance of methodological support of road maps on the example of ‎innovative projects is made.

How Should One Read “The Reader”?

In the final months of her life, Virginia Woolf worked on two projects. One was the posthumously published novel Between the Acts (1941). The other was a literary-historical project, which she provisionally titled “Turning the Page” or “Reading at Random”, but which is now known by the dual titles “Anon” and “The Reader”. Although published in a 1979 eclectic edition, these documents have received little critical attention. This article proposes three novel approaches to this archive of documents. The first takes up the methodology proposed by Woolf’s original titles and reads a single folio of this project at random, paying close material attention to what is on both sides of Woolf’s typescript page. The second approach expands on the materialist slant of the first approach and offers an anatomy of this archive, while the third approach expands on my previous discussion of cataloging and classification, in order to sketch out a historiography of Woolf’s late archive.
