Xi (Alternate Reality Game)
Xi (UK: /ˈsaɪ/ or US: /ˈzaɪ/) was the world's first console-based and virtual world-based alternate reality game. It was a one-time-only play, unfolding in real time, and only available on the PlayStation 3 through the social gaming network, PlayStation Home. The game was an adventure to help find "Jess" and the meaning of Xi by collecting fragments and butterflies found in a series of secret areas in Home that changed frequently. The game also challenged the users to search for clues in the real world. The game was created by nDreams who released several spaces for Xi. The game was promoted through a teaser campaign of clues and hints during the month prior to its release on March 23, 2009. The clues were hidden in the Menu Pad and videos in the central meeting point. The game lasted a total of 12 weeks from its release. Xi and all of the corresponding spaces were exclusive to the European and North American versions of PlayStation Home, though there were also websites, videos, printed media and live events which were accessible to anyone. In September 2009, it was reported that the number of visits to the Xi spaces, including the ones after Xi's completion, had exceeded 5 million visits. A sequel, Xi: Continuum, was released in December 2012.

Lempel-Ziv Complexity
The Lempel-Ziv complexity is a measure that was first presented in the article On the Complexity of Finite Sequences (IEEE Trans. On IT-22,1 1976), by two Israeli computer scientists, Abraham Lempel and Jacob Ziv. This complexity measure is related to Kolmogorov complexity, but the only function it uses is the recursive copy (i.e., the shallow copy). The underlying mechanism in this complexity measure is the starting point for some algorithms for lossless data compression, like LZ77, LZ78 and LZW. Even though it is based on an elementary principle of words copying, this complexity measure is not too restrictive in the sense that it satisfies the main qualities expected by such a measure: sequences with a certain regularity do not have a too large complexity, and the complexity grows as the sequence grows in length and irregularity. The Lempel-Ziv complexity can be used to measure the repetitiveness of binary sequences and text, like song lyrics or prose. Fractal dimension estimates of real-world data have also been shown to correlate with Lempel-Ziv complexity.

Distributed Agile Software Development
Distributed Agile Software Development is a research area that considers the effects of applying the principles of Agile software development to software development in a globally distributed development setting. The goal of applying these principles is overcoming challenges in projects which are geographically distributed. The principles of Agile software development provide structures to promote better communication, which is an important factor in successfully working in a distributed setting. However, not having face-to-face interaction takes away one of the core principles of Agile. This makes Distributed Agile Software Development more challenging than Agile Software Development in general.

Coherent States in Mathematical Physics
Coherent states have been introduced in a physical context, first as quasi-classical states in quantum mechanics, then as the backbone of quantum optics and they are described in that spirit in the article Coherent states (see also). However, they have generated a huge variety of generalizations, which have led to a tremendous amount of literature in mathematical physics. In this article, we sketch the main directions of research on this line. For further details, we refer to several existing surveys.

No Postage Necessary
"No Postage Necessary” is a 2018 American romantic comedy independent film written and directed by Jeremy Culver as his second narrative feature and starring George Blagden, Charleene Closshey, Robbie Kay, Stelio Savante, with Michael Beach and Raymond J. Barry. The film integrates current political happenings—including the Silk Road (online marketplace) (referred to "The Spice Trail" in the film's script), hacktivism, and cyberterrorism—into a dramedy set in Plant City, FL. Principal photography began in Plant City, FL in August 2016 filming on 35mm film. The film initially premiered on October 14, 2017 as an Official Selection of the Heartland Film Festival. The shortened and final version later premiered on June 28, 2018 at the Tampa Theatre in Hillsborough County, Florida where the movie was filmed exclusively. It released in theaters in ten markets across the United States on July 6, 2018 by Two Roads Picture Co. as well as on the decentralized application Vevue, making history as the first film to ever release via blockchain technology and available to stream using cryptocurrency as payment. The film’s script is now part of the Core Collection of the Margaret Herrick Library at the Academy of Motion Picture Arts and Sciences. No Postage Necessary received mixed reviews, with praise for its heartfelt performances, music, production values, and ending that is “satisfying without artifice”, but criticism suggesting it relies too heavily on its unique distribution strategy as its "hook”.

Transformer Architecture and Attention Mechanisms in Genome Data
The emergence and rapid development of deep learning, specifically transformer-based architectures and attention mechanisms, have had transformative implications across several domains, including bioinformatics and genome data analysis. The analogous nature of genome sequences to language texts has enabled the application of techniques that have exhibited success in fields ranging from natural language processing to genomic data.

Assistive Technology for Dementia People
There has been a significant increase in the number of people diagnosed with dementia (PLWD). With diminishing public health and social care resources, there is substantial need for assistive technology-based devices that support independent living. The term assistive technology (AT) is used to describe electronic devices that can be used to support PLWD’s lifestyles. These devices can improve the living standards of PLWD, encourage independence, and may decrease hospital admission rates. Furthermore, assistive technology can reduce the stress of caring for PLWD. AT devices that support remote assistance of PLWD can play a vital role in mitigating loneliness and stress caused by pandemics, reducing the need for home visits and hospitalization, thus reducing the costs associated with caregiver services. Reducing the risks of virus transmission within care homes are also a major consideration.

Park Supplementary Review System
When planning a travel or an adventure, sightseers increasingly rely on opinions posted on the Internet tourism related websites, such as TripAdvisor, Booking.com or Expedia. Unfortunately, beautiful, yet less-known places and rarely visited sightspots often do not accumulate sufficient number of valuable opinions on such websites. An approach is developed  consisting of a system (PSRS) for wildlife sightspots and propose a method for verifying collected geotagged tweets and using them as on-spot reviews.
