Nonlinear science has evolved significantly over the 35 years since the launch of the journal Chaos. This Focus Issue, dedicated to the 80th Birthday of its founding editor-in-chief, David K. Campbell, brings together a selection of contributions on influential topics, many of which were advanced by Campbell's own research program and leadership role. The topics include new phenomena and method development in the realms of network dynamics, machine learning, quantum and material systems, chaos and fractals, localized states, and living systems, with a good balance of literature review, original contributions, and perspectives for future research.
The technology industry offers exciting and diverse career opportunities, ranging from traditional software development to emerging fields such as artificial intelligence, cybersecurity, and data science. Career fairs play a crucial role in helping Computer Science (CS) students understand the various career pathways available to them in the industry. However, limited research exists on how CS students experience and benefit from these events. Through a survey of 86 students, we investigate their motivations for attending, preparation strategies, and learning outcomes, including exposure to new career paths and technologies. We envision our findings providing valuable insights for career services professionals, educators, and industry leaders in improving the career development processes of CS students.
Trades were, and still are part of the daily life of any society and in particular reflect its economic aspect. As far as the Roman period is concerned, Algeria, like its neighbors, has seen a great deal of interest in archaeological research, especially in the urban environment. Many discoveries have been made, notably Latin inscriptions of all kinds. Pagan epitaphs beginning with the formula DMS make up the greatest number of these funerary inscriptions, which are invaluable documents that tell us about people's social lives, and bear witness to the diversity of professional activities and the economic dynamics of these urban centers during the Roman era. In this paper, we attempt to provide an insight into the various trades - craft, administrative, agricultural, commercial, domestic and artistic - and the status of the people who practiced them in Numidian towns such as Cirta, the administrative capital, Cuicul, a medium-sized town, and Thamughadi, the model for a Roman colony. This choice is justified by the greater number of inscriptions.
مثلت الهند تجربة رائدة في العالم النامي من حيث مبادئ الديمقراطية والتعددية الحزبية وإعطاء دور مهم ومؤثر للمعارضة السياسية، وأثبات إمكانية تطبيق الديمقراطية, إذ نجحت في تحقيق الاندماج الوطني للسياسات الهندية على الرغم من وجود بعض المشاكل التي تستجد مع كل متغير, فضلا عن نجاح التجربة البرلمانية الهندية بتنوع أيدولجيات أحزابها السياسية, وقاد راجيف غاندي الهند في مرحلة مهمة من تاريخها، وعمل على تعزيز الأسس الديمقراطية وتقوية حكم القانون في البلاد, وكان تعزيز الديمقراطية أحد أهم أغراض راجيف غاندي, فقام بتعزيز قيم الشفافية والمشاركة الشعبية وحقوق المواطنين, وأدرك غاندي أهمية تمكين الشعب الهندي وضمان مشاركته في صنع القرارات.
GeoAI, or geospatial artificial intelligence, is an exciting new area that leverages artificial intelligence (AI), geospatial big data, and massive computing power to solve problems with high automation and intelligence. This paper reviews the progress of AI in social science research, highlighting important advancements in using GeoAI to fill critical data and knowledge gaps. It also discusses the importance of breaking down data silos, accelerating convergence among GeoAI research methods, as well as moving GeoAI beyond geospatial benefits.

We define deriving semantic class targets as a novel multi-modal task. By doing so, we aim to improve classification schemes in the physical sciences which can be severely abstracted and obfuscating. We address this task for upcoming radio astronomy surveys and present the derived semantic radio galaxy morphology class targets.
In this paper we argue that data science is a coherent and novel approach to empirical problems that, in its most general form, does not build understanding about phenomena. Within the new type of mathematization at work in data science, mathematical methods are not selected because of any relevance for a problem at hand; mathematical methods are applied to a specific problem only by 'forcing', i.e. on the basis of their ability to reorganize the data for further analysis and the intrinsic richness of their mathematical structure. In particular, we argue that deep learning neural networks are best understood within the context of forcing optimization methods. We finally explore the broader question of the appropriateness of data science methods in solving problems. We argue that this question should not be interpreted as a search for a correspondence between phenomena and specific solutions found by data science methods; rather, it is the internal structure of data science methods that is open to precise forms of understanding.
The Department of Archaeology at the University of Sheffield hosted the 2nd Experimental Archaeology Student Symposium (EAStS) between the 28th February and 1st March 2020, following on from the first successful meeting held in Newcastle in October 2018. The Symposium hosted nine papers on a variety of different experimental reconstructions of material production and processes. A discussion panel was undertaken considering the future of experimental archaeology and what its purpose should be in this fast changing world with its diverse problems. The meeting also included an experimental day, during which attendees joined in smelting copper ore, casting bronze objects and working copper into broaches, led by Copper Smith and Experimental Archaeologist Sian Evans.
As a result of the excavation work carried out by the Turkish company for the purpose of building an additional building beside the central library of the University of Omar al- Mukhtar discovered an archaeological site at a depth of a meter, despite the destruction of machines to the roof of the building and commissioned a team from the Department of Archeology Faculty of Arts and the Department of Antiquities to excavate the site and submit a detailed scientific report . . It was discovered in the excavations that lasted for about a month that the site is the expression of a classical cemetery located within the borders of the town of Balagrae with a burial chamber with three terraces engraved in the rocky ground. It was probably a dating site dating back to the second century BC by a coin and some pottery Use the site to live in later periods after removing the constants and modifying the room.In front of the room there is an open area with the entrance which is descending by two stairs of the stairs and in the yard there is a collection of rainwater in the southwest corner of the courtyard. This cemetery is one of the dominant models in Cyrenaica and a number of similar models have been found in the region. Finally, the team assigned a detailed report required the company to stop work and restore the site and change the location of the additional building of the library.

Energy storage providing auxiliary service at the user-side has broad prospects in support of national polices. Three auxiliary services are selected as the application scene for energy storage participating in demand management, peak shaving and demand response. Considering the time value of funds, the user-side energy storage economy model is built. The model comprehensively considers the delayed transformation income, the government subsidy income, the auxiliary service income and the whole-life-cycle cost factor. According to the cost and benefit analysis, an energy storage optimization configuration model is proposed. The model takes maximum revenue of industrial user in energy storage’s whole-life-cycle as the objective function. Then, the Cplex solver is employed to solve the model. In addition, four indexes are utilized to evaluate the financial effect brought by the user-side energy storage. Finally, the revenue and configuration results of the four types of battery energy storage are calculated to verify the validity of the proposed model. In comparison to the value of evaluation index, planning suggestions are provided for the user-side energy storage providing different auxiliary services. Moreover, the conditions of profit and worthwhile investment are obtained through sensitivity analysis of energy storage providing peak shaving service.
Research objectives: Analyzing characteristics of the legal status of Prince Godan, son of Ögedei Khan, who was often mentioned in different imperial, Tibetan, and late medieval Mongolian sources; clarifying the reasons why he was given the title of khan in some sources, though he never possessed this title. The author attempts to define the status, level of power, and real position of Godan among the Chinggisids and in the political structure of the Mongol Empire.
Research materials: The basis for research comprises three groups of historical sources – Mongolian imperial historiography (works of Juwayni and Rashid al-Din, “Yuan shih”, etc.), Tibetan historical works (“The Blue Annals”, “Pagsam-jonsan”, “Debter-chjamtso”), and late medieval Mongolian chronicles created under the influence of Tibetan Buddhist historiography (“Golden Tale”, “Crystal Mirror”, “Yellow History”, “White History”, “Jewel beads”, etc.). The author also used the works of specialists on Mongolian and Tibetan historiography (such as Sh. Bira, R.E. Pubaev, Yu.N. Rerikh, A.D. Tsendina) as well as the works of researchers of political and religious history of the Mongol Empire (such as V.L. Uspenskiy, H. Franke, C.P. Atwood, etc.).
The novelty of the study: It offers a systematization of historical sources of different origins to clarify some aspects of the political biography of Prince Godan, identifying his legal status as a Chinggisid and the ruler of an ulus. At the same time, the author tries to not refute sources with contradicting statements but to clarify the reasons behind such contradictions and to find information which could clarify and complement the data of other sources.
Research results: The author tries to systematize different sources on the status of Prince Godan as one of the key political figures in the history of the Mongol Empire from the 1240s to the beginning of the 1250s and the ruler of a large ulus with substantial level of power, which could be compared with that of rulers of the Golden Horde, the Chaghadaid Ulus, etc. Also, the reasons behind the brief existence of Godan’s ulus and loss of his status already by the time of his direct descendants are analyzed.
