The genomic history of Southern Europe

2018

Farming was first introduced to southeastern Europe in the mid-7th millennium BCE - brought by migrants from Anatolia who settled in the region before spreading throughout Europe. However, the dynamics of the interaction between the first farmers and the indigenous hunter-gatherers remain poorly understood because of the near absence of ancient DNA from the region. We report new genome-wide ancient DNA data from 204 individuals-65 Paleolithic and Mesolithic, 93 Neolithic, and 46 Copper, Bronze and Iron Age-who lived in southeastern Europe and surrounding regions between about 12,000 and 500 BCE. We document that the hunter-gatherer populations of southeastern Europe, the Baltic, and the Nor…

An Efficient Cooperative Smearing Technique for Degraded Historical Documents Images Segmentation

2020

Segmentation is one of the critical steps in historical document image analysis systems that determines the quality of the search, understanding, recognition and interpretation processes. It allows isolating the objects to be considered and separating the regions of interest (paragraphs, lines, words and characters) from other entities (figures, graphs, tables, etc.). This stage follows the thresholding, which aims to improve the quality of the document and to extract its background from its foreground, also for detecting and correcting the skew that leads to redress the document. Here, a hybrid method is proposed in order to locate words and characters in both handwritten and printed docu…

“Not in Possession of Any Weltanschauung”: Otto Neugebauer’s Flight from Nazi Germany and His Search for Objectivity in Mathematics, in Reviewing, an…

2016

Two major factors have to be considered to account for Neugebauer’s “Weltanschauung”, in particular his apparent or real rejection of philosophical or political judgments. On the one hand, Neugebauer, as a mathematician and a historian, had to cope, with the double character of mathematics as a science in its continuity and universality, independent of time, and of mathematics as a characteristic and fundamental product of each individual culture. On the other hand emphasis has to be put on Neugebauer being torn between organizational work (institution building, reviewing, editing) and historical research. One has to consider the vicissitudes of Neugebauer’s long and eventful life, which wa…

History of Data Centre Development

2012

International audience; Computers are used to solve different problems. For solving these problems computer software and hardware are used, but for operations of those computing facilities a Data Centre is necessary. Therefore, development of the data centre is subordinated to solvable tasks and computing resources. We are studying the history of data centres’ development, taking into consideration an understanding of this. In the beginning of the computer era computers were installed in computing centres, because all computing centres have defined requirements according to whom their operation is intended for. Even though the concept of ‘data centre’ itself has been used since the 1990s, t…

Who loves prescriptivism and why? Some aspects of language correctness in Latvia

2015

ABSTRACTTaking into account the crosscultural differences in prescriptive attitudes in various linguistic communities, a theory of three types of prescriptivism – human-oriented, language-oriented, and error-oriented prescriptivism – has been offered [Strelēvica-Osiņa, Dace. [2011] 2012. Kāpēc mēs gribam, lai valoda ir pareiza? Ieskats preskriptīvisma vēsturē, teorijā un praksē [Why Do We Want Language to Be Correct? An Insight into the History, Theory, and Practice of Prescriptivism]. Rīga: LU Latviesu valodas institūts]. This paper presents a synopsis of this theory, with the main emphasis on the situation of Latvia and the attitudes towards language correctness and correction in the Latv…

Beware of the dog! Private linguistic landscapes in two ‘Hungarian’ villages in South-West Slovakia

2015

This study demonstrates how a single type of sign can be connected to language policy on a larger scale. Focusing on the relationship between language policy and language ideologies, I investigate the private Linguistic Landscape (LL) of Hungarians living in two villages in Slovakia. Through an examination of ‘beware of the dog’ signs, it is shown how such signs can be indicative of different language policies. In Slovakia, the Hungarian public LL is often referred to as a threat to the state language and public order. This ideology is reflected on the LL so that there are mostly Slovak-only public signs in bilingual and Hungarian dominant villages. The private realm is the only significant…

History in Lexicography and Lexicography in History: A Reappraisal

2018

This paper aims to provide an overview of anglophone literature on historical lexicography. It begins by defining history and lexicography in order to explore possible relationships between them. What follows is a critical discussion of two analytical perspectives: “history in lexicography” and “lexicography in history.” The former seeks to explain what historical information is, how history has permeated dictionaries, particularly those compiled on historical principles, and why the historical dictionary needs to be re-interpreted along new lines. The latter, by contrast, attempts to identify the main elements involved in the writing of a history of lexicography. Since no historical accoun…

Past, Present and Future Perspectives on Halloysite Clay Minerals

2020

Halloysite nanotubes (HNTs), clay minerals belonging to the kaolin groups, are emerging nanomaterials which have attracted the attention of the scientific community due to their interesting features, such as low-cost, availability and biocompatibility. In addition, their large surface area and tubular structure have led to HNTs’ application in different industrial purposes. This review reports a comprehensive overview of the historical background of HNT utilization in the last 20 years. In particular it will focus on the functionalization of the surfaces, both supramolecular and covalent, following applications in several fields, including biomedicine, environmental science and catalysis.

First fossil record (Middle Miocene) of the viper shark Trigonognathus Mochizuki and Ohe, 1990, in the Mediterranean realm

2022

The genus Trigonognathus Mochizuki and Ohe, 1990, is a monospecific taxon of `lantern sharks¿ (i.e., family Etmopteridae), a group of small-sized bioluminescent deep-sea chondrichthyans, ranging in mature male specimens between 42¿47 cm total length, and at least 52 cm for females (Ebert et al., 2021). This shark inhabits the upper continental slopes as well as the uppermost slope of seamounts, often at the bottom, at depths ranging between 250¿1000 m, but has been caught at 150 m and 270 m in deep open waters (Mochizuki and Ohe, 1990; Compagno et al., 2005; Ebert et al., 2021). Only two species have been described thus far, the extant species Trigonognathus kabeyai Mochizuki and Ohe, 1990,…
