All-sky search for short gravitational-wave bursts in the second Advanced LIGO and Advanced Virgo run
2019
We present the results of a search for short-duration gravitational-wave transients in the data from the second observing run of Advanced LIGO and Advanced Virgo. We search for gravitational-wave transients with a duration of milliseconds to approximately one second in the 32-4096 Hz frequency band with minimal assumptions about the signal properties, thus targeting a wide variety of sources. We also perform a matched-filter search for gravitational-wave transients from cosmic string cusps for which the waveform is well-modeled. The unmodeled search detected gravitational waves from several binary black hole mergers which have been identified by previous analyses. No other significant event…
Fluorescent biological aerosol particle measurements at a tropical high-altitude site in southern India during the southwest monsoon season
2016
An ultraviolet aerodynamic particle sizer (UV-APS) was continuously operated for the first time during two seasons to sample the contrasting winds during monsoon and winter to characterize the properties of fluorescent biological aerosol particles (FBAPs), at a high-altitude site in India. Averaged over the entire monsoon campaign (1 June–21 August 2014), the arithmetic mean number and mass concentrations of coarse-mode (> 1 µm) FBAPs were 0.02 cm−3 and 0.24 µg m−3, respectively, which corresponded to ∼ 2 and 6 % of total aerosol loading, respectively. Average FBAP number size distribution exhibited a peak at ∼ 3 µm, which is attributed to the fungal spores, as supported by scanning …
Banner clouds observed at Mount Zugspitze
2012
Abstract. Systematic observations of banner clouds at Mount Zugspitze in the Bavarian Alps are presented and discussed. One set of observations draws on daily time lapse movies, which were taken over several years at this mountain. Identifying banner clouds with the help of these movies and using simultaneous observations of standard variables at the summit of the mountain provides climatological information regarding the banner clouds. In addition, a week-long measurement campaign with an entire suite of instruments was carried through yielding a comprehensive set of data for two specific banner cloud events. The duration of banner cloud events has a long-tailed distribution with a mean of…
Spatio-temporal variability of fog-water collection in the eastern Iberian Peninsula: 2003-2012
2019
Abstract Among the different inputs involved in the hydrological system, fog water measured by man-made passive devices is one of the most unknown components, although it could be an additional water resource for specific environmental applications (forest restoration, forest firefighting, etc.). Focusing on the Mediterranean Iberian Peninsula, the aim of this work is to quantify fog-water collected by a 24-fog-stations network spread across three latitudinal sectors with different locations (coastal, pre-littoral and inland), and to determine the most productive sites. Measurements from the network show that distance-to-sea, latitude or elevation differences between stations are factors af…
PCA analysis of wind direction climate in the baltic states
2021
Wind direction is one of the fundamental parameters of weather. In this study we investigate the wind direction climate 10 m above surface level in the Baltic States (Estonia, Latvia, Lithuania). The analysis of wind direction over larger regions is usually hindered by the fact that wind direction is a circular variable, which means that averaged values are meaningless. Here we show how Principal Component Analysis (PCA) can be applied to give a large scale overview of typical wind direction patterns in the region. Here we apply PCA to both observational and reanalysis data. The most significant wind direction patterns are detected in both synoptic scale and mesoscale, and we attempt to lin…
La Direttiva 2014/104/UE sul risarcimento dei danni per violazione della normativa antitrust dell'Unione Europea e la sua attuazione in Italia
2019
Con il d.lg. 13 gennaio 2017, n. 3, è stata data attuazione alla direttiva 2014/104/UE del Parlamento e del Consiglio del 26 novembre 2014, relativa a determinate norme che regolano le azioni per il risarcimento del danno ai sensi del diritto nazionale per violazioni delle disposizioni del diritto della concorrenza degli Stati membri e dell'Unione europea. Il saggio esamina criticamente le novità e le principali questioni interpretative poste dal nuovo testo. With the legislative decree 13 January 2017, n. 3, has been implemented in Italy the 2014/104 / EU directive of the Parliament and of the Council of 26 November 2014 , concerning certain rules governing actions for damages under nation…
Beyond Evidentiality. The epistemic function of the suffix -wa in Aymara
2021
In contrast to the specialized literature (Hardman 1986, 2001; Martinez-Vera 2020), this paper questions the direct evidential function of the sentence-type suffix -wa in «Northern Aymara» (Cerrón-Palomino 2000), an understudied Andean language spoken in the area around Lake Titicaca. By taking a narrow perspective on evidentiality, it proposes that -wa is a modal epistemic marker that indicates the speaker’s high commitment to information. Semantic considerations that support this proposal focus on both the interplay of -wa with other grammatical categories and its distribution within the sentence. Additionally, considerations on the scope properties of the suffix, as applied by Hengeveld …
Family Matters : Abusing Family Refresh Tokens to Gain Unauthorised Access to Microsoft Cloud Services Exploratory Study of Azure Active Directory Fa…
2022
Azure Active Directory (Azure AD) is an identity and access management service used by Microsoft 365 and Azure services and thousands of third-party service providers. Azure AD uses OIDC and OAuth protocols for authentication and authorisation, respectively. OAuth authorisation involves four parties: client, resource owner, resource server, and authorisation server. The resource owner can access the resource server using the specific client after the authorisation server has authorised the access. The authorisation is presented using a cryptographically signed Access Token, which includes the identity of the resource owner, client, and resource. During the authorisation, Azure AD assigns Ac…
Exploring Azure Active Directory Attack Surface: Enumerating Authentication Methods with Open-Source Intelligence Tools
2022
Azure Active Directory (Azure AD) is Microsoft’s identity and access management service used globally by 90 per cent of Fortune 500 companies and many other organisations. Recent attacks by nation-state adversaries have targeted these organisations by exploiting known attack vectors. In this paper, open-source intelligence (OSINT) is gathered from organisations using Azure AD to explore the current attack surface. OSINT is collected from Fortune 500 companies and top 2000 universities globally. The collected OSINT includes authentication methods used by the organisation and the full name and phone number of the primary technical contact. The findings reveal that most organisations are using…
In light of the ends. Copyright hysteresis and private copy exception after the British Academy of Songwriters, Composers and Authors (BASCA) and oth…
2015
In British Academy of Songwriters, Composers and Authors (BASCA) and others v Secretary of State for Business, Innovation and Skills, the High Court of Justice in matter of private copy exception provides the twofold prime opportunity to shed light on the state of the art of copyright in the UK and to flesh out the idea of 'legal hysteresis’. I support the reintroduction of the private copy exception, possibly in a less narrow fashion, and I explain the reasons why I am confident that my expectations will be fulfilled.
