A great progress has been made in strangeness nuclear physics in the past decade. Examples are; 1) The "hyperfine" structure of hypernuclei were measured with the Hyperball, and ΛN spin dependent interactions in p -shell hypernuclei were determined. 2) The "complete measurements" of the weak decay of hypernuclei were made and the np ratio puzzle in the non-mesonic decay was solved. 3) The discovery of a clean event of "Lambpha" and determination of its binding energy concluded that the Λ-Λ interaction is weak attractive. However, we still have important questions to be answered in this field, especially in relation with QCD and nuclear physics. For the future strangeness nuclear physics, we have and will have facilities such as JLab, SPring-8, Daphne, J-PARC, FAIR. We discuss experimental challenges in the strangeness nuclear physics and related fields in the next decade.

This paper summarizes the progress made in the quest to establish a Cybersickness Dose Value (CSDV). The Motion Sickness Dose Value (MSDV), reported in the British Standard BS6841, has been used to predict the severity of seasickness since 1987. In 1999, the authors of this paper proposed a CSDV formulation with a structure similar to that of the MSDV (So, 1999). Since then, several experiments and simulation studies have been conducted to modify and develop the proposed CSDV formula. In particular, progress has been made in (i) the methods to measure CSDV, (ii) the determination of a frequency weighting curve to equalize the non-linear relationship between the navigation velocity and levels of cybersickness, and (iii) the detailed formulation of CSDV. This paper summarizes the past progress and reports on the current effort in developing a CSDV.

Requirements of form (such as writing) are not as important today as they were in the past. As a general rule, contracts can be made in any form and can be proved by any means, although there remain exceptional cases where the law does insist upon requirements of form. This chapter, which considers the reasons for continued reliance upon requirements of form, along with the criticisms levelled against such requirements, begins by explaining why legal systems impose formal requirements upon contracting parties. It then outlines the formal requirements in English contract law, followed by a discussion of the future of formal requirements, noting the distinction between cases where the contract must be made in writing and cases in which contracts must be evidenced in writing.

The past two decades have seen great progress in recognizing the importance of inflammation in medicine. Increased focus on inflammation in both prevention and treatment has improved outcomes and quality of life in chronic diseases. Science has improved our understanding of inflammation’s many causes and effects on health, and many advances have been made in the availability of targeted therapeutic options for treating inflammation. This chapter gives an overview of recognizing the many causes of inflammation, its many targeted treatments strategies, and the questions that still surround it. It discusses several integrative approaches to reducing inflammation, including exercise, diet, and different strategies for managing sleep, mood, and stress, such as meditation and massage.

Whilst online dating has been around for several years; immersive technologies are relatively new to this type of interaction. The first forays into immersive VR online dating have only just being made in the past year. To what degree this type of technology will change the way that we date is potentially quite different from the current way that online dates are conducted. The way the technology works could make virtual dates seem as real as a physical date. Understanding how immersive technology functions gives some insights into the future of online dating and also the impact on the digital economy.

Carborane Anions

This article highlights the achievements in the chemistry of supercarboranes (carboranes with more than 12 vertices) in the past decade and the future perspectives. The chemistry of boron clusters has been dominated by 12-vertex carboranes for several decades. Only in recent years has significant progress been made in the chemistry of supercarboranes. Such a breakthrough relies on the use of CAd (carbon-atoms-adjacent) 12-vertex nido-carborane anions as starting materials. A series of 13- and 14-vertex carboranes as well as their corresponding 14- and 15-vertex metallacarboranes have been prepared and structurally characterized. Reactions of supercarboranes with reducing agents, electrophiles, and nucleophiles are studied, which reveal a more diverse and richer reaction chemistry than their icosahedral cousins.

Regeneration, the replacement of body parts in a living animal, has excited scientists for centuries and our knowledge of vertebrate appendage regeneration has increased significantly over the past decades. While the ability of amniotes to regenerate body parts is very limited, members of other vertebrate clades have been shown to have rather high regenerative capacities. Among tetrapods (four-limbed vertebrates), only salamanders show unparalleled capacities of epimorphic tissue regeneration including replacement of organ and body parts in an apparently perfect fashion. The closest living relatives of Tetrapoda, the lungfish, show regenerative abilities that are comparable to those of salamanders and recent studies suggest that these high regenerative capacities may indeed be ancestral for bony fish (osteichthyans) including tetrapods. While great progress has been made in recent years in understanding the cellular and molecular mechanisms deployed during appendage regeneration, comparatively few studies have investigated gross morphological and histological features of regenerated fins and limbs. Likewise, rather little is known about how fin regeneration compares morphologically to salamander limb regeneration. In this study, we investigated the morphology and histology of regenerated fins in all three modern lungfish families. Data from histological serial sections, 3D reconstructions, and x-ray microtomography scans were analyzed to assess morphological features, quality and pathologies in lungfish fin regenerates. We found several anomalies resulting from imperfect regeneration in regenerated fins in all investigated lungfish species, including fusion of skeletal elements, additional or fewer elements, and distal branching. The similarity of patterns in regeneration abnormalities compared to salamander limb regeneration lends further support to the hypothesis that high regenerative capacities are plesiomorphic for sarcopterygians.

Summary Judgment

Alberta’s law of civil procedure, and summary judgment in particular, has experienced a culture shift since the Supreme Court of Canada’s ruling in Hryniak v. Mauldin. This article asks whether litigation directed toward a conventional trial is now, or is soon to be, a thing of the past. Although intended to revive traditional trials as a realistic and timely resolution option, it is impossible to say yet if this will be Hryniak’s legacy in Alberta. Three things are clear in post-Hryniak Albertan jurisprudence, however: first, the Hryniak test governs the determination of summary judgment applications in Alberta; second, Alberta courts have embraced the call for proportionality in litigation procedure; and third, the Hryniak culture shift creates uncertainty for Alberta litigants.

Great progress has been made in the tandem annulation of enynes in the past few years. This review only presents the corresponding reactions of 1,3-enyne structural motifs to provide the functionalized pyridine and pyrrole derivatives. The functionalization reactions cover iodination, bromination, trifluoromethylation, azidation, carbonylation, arylation, alkylation, selenylation, sulfenylation, amidation, esterification, and hydroxylation. We also briefly introduce the applications of the products and the reaction mechanisms for the synthesis of corresponding N-heterocycles.

This review covers the five themes of Temporal Turn: Art and Speculation in Contemporary Asia, and suggests the greatest achievement of the exhibition, while also offering suggestions to improve its impact. The paper also delves into the rapid changes in Asia over the past 50 years, including political, cultural, and population transformation, tying them to specific works in the exhibition. The article selects artworks in Temporal Turn emphasizing these large, rapid changes made by contemporary Asian artists. Research into the economic, political, and cultural facets of East Asian culture is used to back claims made in the paper. Furthermore, the paper proposes how the viewer should respond to the exhibition with thematic context, suggesting it disorients its audience in time and reality.
