Solar neutrino spectroscopy in Borexino
2018
International audience; In more than ten years of operation, Borexino has performed a precision measurement of the solar neutrino spectrum, resolving almost all spectral components originating from the proton-proton fusion chain. The presentation will review the results recently released for the second data taking phase 2012–2016 during which the detector excelled by its unprecedentedly low background levels. New results on the rate of pp, 7Be, pep and 8B neutrinos as well as their implications for solar neutrino oscillations and metallicity are discussed.
Increasing the Astrophysical Reach of the Advanced Virgo Detector via the Application of Squeezed Vacuum States of Light
2019
Current interferometric gravitational-wave detectors are limited by quantum noise over a wide range of their measurement bandwidth. One method to overcome the quantum limit is the injection of squeezed vacuum states of light into the interferometer's dark port. Here, we report on the successful application of this quantum technology to improve the shot noise limited sensitivity of the Advanced Virgo gravitational-wave detector. A sensitivity enhancement of up to 3.2±0.1 dB beyond the shot noise limit is achieved. This nonclassical improvement corresponds to a 5%-8% increase of the binary neutron star horizon. The squeezing injection was fully automated and over the first 5 months of the thi…
The advanced Virgo longitudinal control system for the O2 observing run
2020
Following a successful period of data-taking between 2006 and 2011, the Virgo gravitational-wave detector was taken offline for a major upgrade. The changes made to the instrument significantly increased the complexity of the control systems and meant that an extended period of commissioning was required to reach a sensitivity appropriate for science data-taking. This commissioning period was completed in July of 2017 and the second-generation Advanced Virgo detector went on to join the Advanced LIGO detectors in the O2 science run in August of the same year. The upgraded detector was approximately twice as sensitive to binary neutron star mergers as the first-generation instrument. During …
Vārddarināšanas paņēmieni rakstu par biznesu virsrakstos
2022
Laikrakstu virsraksti informē lasītājus par aktualitātēm un pārliecina tos izlasīt laikrakstu rakstus, izmantojot uzmanību piesaistošu un daudzveidīgu valodu, radītu vārddarināšanas rezultātā. Bakalaura darbā ir analizētas vārddarināšanas metodes tiešsaistes laikrakstu virsrakstos saistībā ar Krievijai nesen uzliktajām sankcijām, izmantojot teorijas un leksisko analīzi. Pētījuma rezultāti atklāj, ka atvasinājumi un salikteņi ir analizētajos tiešsaistes virsrakstos visbiežāk izmantotie vārdi, kas radīti vārddarināšanas rezultātā, no kuriem krievu-, rietumu, globālā, ekonomisks, maksājums un inflācija ir visbiežāk atvasinātie vārdi. Saīsinājumu izmantošana kā vārddarināšanas metode atšķiras s…

SOME EXAMPLES RELATED TO A CLASS OF FUNCTIONALS WITHOUT GLOBAL MINIMA
2012
Abstract: In this paper, we provide six examples which show the sharpness of the assumptions of a recent deep result of Ricceri about a class of functionals without global minima.
Costrutti locativi e non locativi con mettere
2013
Sentence (a) Ada mise Pio nel sacco is ambiguous: one of its meanings is literal (Ada put Pio in the sack), whereas the other is figurative (Ada fooled / outsmarted Pio). Such ambiguity is not present in sentence (b) Ada mise Pio in un sacco. On the surface, (b) differs from (a) only insofar as the indefinite article is employed, but conveys a literal meaning exclusively (Ada put Pio in a sack). The ambiguity of sentence (a) is derived from the existence of two constructions employing mettere. The prepositional phrase of one of them displays standard paradigmatic properties and conveys literal (i.e. locative) meaning, whereas the other has no locative value and is highly constrained (e.g. n…
"Rokuja et pääse karkuun ilman jumpbootseja" : nonce borrowings in video gaming environment
2015
Videopelit ovat viime vuosina nousseet valtavirran vapaa-ajan aktiviteetiksi esimerkiksi television katselun ja urheilun ohelle. Videopelejä voi pelata monilla eri laitteilla kuten pelikonsoleilla, tietokoneilla sekä puhelimilla ja muilla kannettavilla laitteilla. Internet on myös mahdollistanut pelaamisen sekä kommunikoinnin pelaajien välillä paikasta riippumatta. Pelien ollessa valtaosin englanninkielisiä, pelaajat, jotka pelaavat yhdessä muiden kansalaisuuksien kanssa, valitsevat yleensä englannin yhteiseksi kommunikoinnin välineeksi. Englannin kielen asema sekä peleissä että tietokoneympäristössä yleensä on johtanut siihen, että esimerkiksi suomalaiset pelaajat käyttävät englanninkielis…
Framing Effects on Online Security Behavior
2020
We conducted an incentivized lab experiment examining the effect of gain vs. loss-framed warning messages on online security behavior. We measured the probability of suffering a cyberattack during the experiment as the result of five specific security behaviors: choosing a safe connection, providing minimum information during the sign-up process, choosing a strong password, choosing a trusted vendor, and logging-out. A loss-framed message led to more secure behavior during the experiment. The experiment also measured the effect of trusting beliefs and cybersecurity knowledge. Trusting beliefs had a negative effect on security behavior, while cybersecurity knowledge had a positive effect.
Web crawling dla celów lingwistycznych. Wybrane aspekty gromadzenia i analizy danych tekstowych na przykładzie rosyjskojęzycznych newsów internetowych
2021
Autor niniejszego artykułu zgromadził ok. 2,7 mln rosyjskojęzycznych newsów internetowych. Zasadnicze cele tego tekstu stanowią: omówienie pojęcia web crawlingu w odniesieniu do pozyskiwania internetowych danych tekstowych, omówienie kwestii strukturyzacji takich danych w nieanotowanych korpusach tekstowych, a także przedstawienie wybranych aspektów analizy danych strukturyzowanych w ten sposób. Autor rozpatruje newsy internetowe jako połączenie tekstu zasadniczego oraz identyfikujących i charakteryzujących go metadanych (wyróżnionych podczas automatycznej ich ekscerpcji ze stron internetowych). Rozdział newsów na tekst zasadniczy i metadane stwarza możliwość przeprowadzenia ich analizy z d…
