The Minimum Amount of Useful Space: New Results and New Directions
2014
We consider minimal space requirements when using memory with restricted access policy (pushdown - hence giving pushdown automata (PDAs), and counter - hence giving counter automata (CAs)) in connection with two-way and realtime head motion. The main results are that: (i) loglogn is a tight space lower bound for accepting general nonregular languages on weak realtime PDAs, (ii) there exist unary nonregular languages accepted by realtime alternating CAs within weak logn space, (iii) there exist nonregular languages accepted by two-way DPADs within strong loglogn space, and, (iv) there exist unary nonregular languages accepted by two-way CAs with quantum and classical states within middle log…
The Symbolical Realm and Historical Framework of the Contrade
2017
The chapter describes the contemporary symbolism of the contrade and its historic development in order to allow the reader to follow the subsequent analysis of the content of the contrade’s websites, in which symbols play a key role. It suggests that the contrade of Siena make significant use of mediaeval and Renaissance signs and symbol s such as particular colours, flags, and instruments. Members of a contrada build a community based on a specific district of Siena, and their lives are heavily focused on what is deemed necessary to the win a horse race called palio .
One-Counter Verifiers for Decidable Languages
2013
Condon and Lipton (FOCS 1989) showed that the class of languages having a space-bounded interactive proof system (IPS) is a proper subset of decidable languages, where the verifier is a probabilistic Turing machine. In this paper, we show that if we use architecturally restricted verifiers instead of restricting the working memory, i.e. replacing the working tape(s) with a single counter, we can define some IPS’s for each decidable language. Such verifiers are called two-way probabilistic one-counter automata (2pca’s). Then, we show that by adding a fixed-size quantum memory to a 2pca, called a two-way one-counter automaton with quantum and classical states (2qcca), the protocol can be spac…
The generalizability of Older Adult Self-Report (OASR) syndromes of psychopathology across 20 societies
2020
Contains fulltext : 217516.pdf (Publisher’s version ) (Closed access) Objectives: As the world population ages, psychiatrists will increasingly need instruments for measuring constructs of psychopathology that are generalizable to diverse elders. The study tested whether syndromes of co-occurring problems derived from self-ratings of psychopathology by US elders would fit self-ratings by elders in 19 other societies. Methods/design: The Older Adult Self-Report (OASR) was completed by 12 826 adults who were 60 to 102 years old in 19 societies from North and South America, Asia, and Eastern, Northern, Southern, and Western Europe, plus the United States. Individual and multigroup confirmatory…
Employment status and occupational positions of childhood cancer survivors from Denmark, Finland and Sweden: A Nordic register-based cohort study fro…
2021
Background: A childhood cancer diagnosis and late effects of treatment may affect survivors' possibilities of employment or highly skilled occupations later in life. In this study, we compared the employment and occupational status of childhood cancer survivors with population comparisons and siblings.Methods: In a cohort study based on Nordic registers, we identified 10 461 survivors of childhood cancer diagnosed before age 20 years in Denmark, Finland and Sweden since 1971. Survivors were compared with 48 928 population comparisons matched to survivors by age, sex and geographical region and 12 605 siblings of survivors. Annual outcome information on employment, unemployment, health-relat…
PESI - a taxonomic backbone for Europe
2015
Reliable taxonomy underpins communication in all of biology, not least nature conservation and sustainable use of ecosystem resources. The flexibility of taxonomic interpretations, however, presents a serious challenge for end-users of taxonomic concepts. Users need standardised and continuously harmonised taxonomic reference systems, as well as highquality and complete taxonomic data sets, but these are generally lacking for nonspecialists. The solution is in dynamic, expertly curated web-based taxonomic tools. The Pan-European Species-directories Infrastructure (PESI) worked to solve this key issue by providing a taxonomic e-infrastructure for Europe. It strengthened the relevant social (…
Association of maternal prenatal smoking GFI1-locus and cardio-metabolic phenotypes in 18,212 adults
2018
Background: DNA methylation at the GFI1-locus has been repeatedly associated with exposure to smoking from the foetal period onwards. We explored whether DNA methylation may be a mechanism that links exposure to maternal prenatal smoking with offspring's adult cardio-metabolic health.Methods: We meta-analysed the association between DNA methylation at GFI1-locus with maternal prenatal smoking, adult own smoking, and cardio-metabolic phenotypes in 22 population-based studies from Europe, Australia, and USA (n= 18,212). DNA methylation at the GFI1-locus was measured in whole-blood. Multivariable regression models were fitted to examine its association with exposure to prenatal and own adult s…
Prä- und postnatales Nierenscreening im Vergleich: eine Analyse von 34.450 Neugeborenen des Geburtenregisters Mainzer Modell
2002
Zielsetzung. Fehlbildungen des internen Urogenitalsystems sind haufig und stellen die zweithaufigste Organkategorie dar. Anhand des Mainzer Geburtenregisters werden populationsbezogene Pravalenzen von Nierenfehlbildungen, die Sensitivitat des pranatalen Ultraschalls und die Haufigkeit operationsbedurftiger Befunde ermittelt. Material und Methode. Im Zeitraum von 1990–2001 erhielten alle in Mainz geborenen Kinder neben einer klinischen Untersuchung eine Ultraschalluntersuchung der ableitenden Harnwege. Bei Totgeborenen, Spontanaborten (≥15. SSW) und induzierten Aborten wurden die Befunde der Pathologie in die Erfassung einbezogen. Seit 1996 (nach Einfuhrung des Fehlbildungsschalles in die Mu…
Variació funcional i expressió de l'evidencialitat en el català del s. XV: la traducció de Les paradoxa de Ferran Valentí
2013
Resum: L’anàlisi comparativa de l’obra de Ciceró Paradoxa Stoicorum i la traducció del s. XV fetaper Ferran Valentí és d’alguna utilitat des de la perspectiva lingüística. En aquest article, examinemun element d’interès per a la semàntica del català: l’expressió de l’evidencialitat mitjançant algunsverbs com jutjar, estimar, pensar, sentir, etc. En aquest estudi, observem com tradueix Valentí elsverbs llatins en català i provem de reconèixer quins evidentials del català medieval són el resultatd’una interferència del llatí. L’objectiu és establir el valor evidencial de cadascun d’aquests verbs i feraixí un primer acostament a l’expressió de l’evidencialitat en un registre formal del català …
Genome-wide meta-analysis identifies six novel loci associated with habitual coffee consumption
2015
Contains fulltext : 155360.pdf (Publisher’s version ) (Closed access) Coffee, a major dietary source of caffeine, is among the most widely consumed beverages in the world and has received considerable attention regarding health risks and benefits. We conducted a genome-wide (GW) meta-analysis of predominately regular-type coffee consumption (cups per day) among up to 91,462 coffee consumers of European ancestry with top single-nucleotide polymorphisms (SNPs) followed-up in ~30 062 and 7964 coffee consumers of European and African-American ancestry, respectively. Studies from both stages were combined in a trans-ethnic meta-analysis. Confirmed loci were examined for putative functional and b…
