description: Motivated by recent experiments pertaining to the interaction of weak SASE-FEL pulses with atoms and molecules, we investigate the conditions under which such interactions can be described in the framework of a simple phase-diffusion model with decorrelated atom-field dynamics. The nature of the fluctuations that are inevitably present in SASE-FEL pulses is shown to play a pivotal role in the success of the decorrelation. Our analysis is performed in connection with specific recent experimental results from FLASH in the soft X-ray regime.

description: We demonstrate an amplitude-to-phase (AM-PM) conversion coefficient for a balanced optical-microwave phase detector (BOM-PD) of 0.001 rad, corresponding to AM-PM induced phase noise 60 dB below the single-sideband relative intensity noise of the laser. This enables us to generate 8 GHz microwave signals from a commercial Er-fibre comb with a single-sideband residual phase noise of -131 dBc/Hz at 1 Hz offset frequency and -148 dBc/Hz at 1 kHz offset frequency.

description: This paper analyzes the implications of different designs of policies, which aim to contain the diffusion of the SARS-CoV-2 virus, with respect to induced economic loss and virus mortality. An agent-based simulation model is implemented and calibrated with German data, which combines the representation of a simple multi-sectoral closed economy with the explicit incorporation of virus transmission channels at the workplace, during shopping activities and other social contacts. It is demonstrated that under a policy resembling German containment measures the model closely reproduces the dynamics of pandemic and economic variables in the aftermath of the COVID-19 outbreak in Germany. Exploring alternative policy designs shows that any efficient policy should impose a low threshold of newly infected for moving from the lock-down to the opening-up stage and in the opening-up stage all restrictions on economic activity should be lifted. With respect to the reduction of consumption activities during the lock-down a trade-off between the induced GDP loss and the resulting mortality emerges. Regardless of the chosen design of the containment measures, the introduction of complementary economic support measures substantially reduces the induced GDP loss and leads to a reduction of the public debt accumulated during the considered time interval. The efficient design of containment policies changes substantially if lifting economic restrictions during the opening-up stage also results in reduced effectiveness of the individual prevention measures by agents.
Strict inequality of Robin eigenvalues for elliptic differential operators on Lipschitz domains

description: On a bounded Lipschitz domain we consider two selfadjoint operator realizations of the same second order elliptic differential expression subject to Robin boundary conditions, where the coefficients in the boundary conditions are functions. We prove that inequality between these functions on the boundary implies strict inequality between the eigenvalues of the two operators, provided that the inequality of the functions in the boundary conditions is strict on an arbitrarily small nonempty, open set.

description: A fabrication method for positioning and embedding a single-walled carbon nanotube (SWNT) across the diameter of a solid state nanopore is presented. Chemical vapor deposition (CVD) is used to grow SWNTs over arrays of focused ion beam (FIB) milled pores in a thin silicon nitride membrane. This typically yields at least one pore whose diameter is centrally crossed by a SWNT. The final diameter of the FIB pore is adjusted to create a nanopore of any desired diameter by atomic layer deposition (ALD), simultaneously embedding and insulating the SWNT everywhere but in the region that crosses the diameter of the final nanopore, where it remains pristine and bare. This nanotube-articulated nanopore is an important step towards the realization of a new type of detector for biomolecule sensing and electronic characterization, including DNA sequencing.

description: UX strategy is an indispensable part of UX management. However, several practical questions exist for many UX professionals: Which levels, departments, and job roles impact UX strategy, and on which of these does UX strategy have an impact in return? Which factors play a role in establishing UX strategy? We conducted a workshop with UX professionals to find answers to these questions. Our results indicate that UX strategy relates business and UX, and thus covers a large variety of areas. However, we also discovered significant uncertainty about how to create and establish UX strategy. From the UX professionals’ points of view, there is a high need for creating awareness for UX strategy, both within and outside the UX community, and especially in C-level management. Based on the results, we derive recommendations and follow-up steps for further engagement with UX strategy.

description: The UKIDSS Large Area Survey (LAS) began in 2005, with the start of the UKIDSS program as a 7 year effort to survey roughly 4000 deg$^2$ at high galactic latitudes in Y, J, H and K bands. The survey also included a significant quantity of 2-epoch J band observations, with an epoch baseline greater than 2 years to calculate proper motions. We present a near infrared proper motion catalogue for the 1500 deg$^2$ of the 2 epoch LAS data, which includes 135,625 stellar sources and a further 88,324 with ambiguous morphological classifications, all with motions detected above the 5$σ$ level. We developed a custom proper motion pipeline which we describe here. Our catalogue agrees well with the proper motion data supplied for a 300 deg$^2$ subset in the current WFCAM Science Archive (WSA) tenth data release (DR10) catalogue, and in various optical catalogues, but it benefits from a larger matching radius and hence a larger upper proper motion detection limit. We provide absolute proper motions, using LAS galaxies for the relative to absolute correction. By using local 2nd order polynomial transformations, as opposed to linear transformations in the WSA, we correct better for any local distortions in the focal plane, not including the radial distortion that is removed by the UKIDSS pipeline. We present the results of proper motion searches for new brown dwarfs and white dwarfs. We discuss 41 sources in the WSA DR10 overlap with our catalogue with proper motions $>$300 $mas yr^{-1}$, several of which are new detections. We present 15 new candidate ultra-cool dwarf binary systems.

description: Kontext: Digitale Ökosysteme bestehen aus mindestens zwei Kundengruppen – den Konsumenten und den Anbietern. Untersucht wurde bisher, wie die Konsumenten auf die Assets des digitalen Ökosystems zugreifen, jedoch nicht, wie Anbieter auf die Plattformen digitaler Ökosysteme gelangen und wie sich ihre Customer Journey gestaltet. Ziel: Demnach gilt es, eine Ecosystem Journey zu entwickeln, d. h. eine Journey, die sowohl aus einer Konsumenten-Journey als auch aus einer Anbieter-Journey besteht. Da Konsumenten-Journeys in der Literatur bereits betrachtet wurden, liegt in dieser Arbeit der Fokus auf der Konzeption der Customer Journey der Anbieter, also auf der Anbieter-Journey in einem digitalen Ökosystem. Methode: Hierzu wurden 15 digitale Ökosysteme untersucht. Es wurden gemeinsame Merkmale zwischen den Customer Journeys der 15 digitalen Ökosysteme extrahiert und darauf aufbauend wurde ein Ansatz entwickelt, der eine strukturierte Entwicklung zukünftiger Anbieter-Journeys ermöglicht. Ergebnis: Die konzipierte Anbieter-Journey besteht aus sieben Phasen, die jeweils zugehörige Ziele, Kernfragen, Teilfragen und Maßnahmen enthalten. Dies ermöglicht ein strukturiertes Vorgehen sowohl innerhalb der Phasen als auch über die Phasen hinweg, um einer Anbieter Journey. Fazit: Der entwickelte Ansatz liefert einen ersten Ansatzpunkt zu einer strukturierten Entwicklung eine Anbieter-Journey systematisch zu erstellen. Gleichwohl handelt es sich bisher um ein theoretisches Konstrukt, welches im nächsten Schritt in der Praxis evaluiert wird.

description: The three standard products (the Cartesian, the direct and the strong product) of undirected graphs have been wellinvestigated, unique prime factor decomposition (PFD) are known and polynomial time algorithms have been established for determining the prime factors. For directed graphs, unique PFD results with respect to the standard products are known. However, there is still a lack of algorithms, that computes the PFD of directed graphs with respect to the direct and the strong product in general. In this contribution, we focus on the algorithmic aspects for determining the PFD of directed graphs with respect to the strong product. Essential for computing the prime factors is the construction of a so-called Cartesian skeleton. This article introduces the notion of the Cartesian skeleton of directed graphs as a generalization of the Cartesian skeleton of undirected graphs. We provide new, fast and transparent algorithms for its construction. Moreover, we present a first polynomial time algorithm for determining the PFD with respect to the strong product of arbitrary connected digraphs.

description: This paper reflects on an interdisciplinary and method triangulation approach for digital product development. The research project "Smart Inclusivity for homeless people" (SIWo), conducted by the Ohm, is cited as an example. In the project, research methods from qualitative social sciences involving group discussions and interviews were combined with a human-centered design process to develop customized digital products that aim to support homeless people in their everyday life. In the Social Sciences Research subproject, (digital) needs of homeless people were identified. In a human-centered design process, these results were used to define the context of use for product development. The project yielded several digital solutions, including apps for information needs like "Stromer Max" and "Schlaue Lise," along with concepts for housing and peer support apps. Additionally, a public Wi-Fi and charging station was installed in Nuremberg. Incorporating qualitative social research methods into the product development process can provide valuable insights and improve the human-centered design process, especially in the context of addressing social issues like homelessness. These methods help understand user needs and preferences in a more nuanced way than traditional Design Thinking approaches. However, challenges of time-intensive evaluations and issues of bridging the gap between social research and technical product development have to be faced. Overall, the paper emphasizes the potential for societal transformations through such interdisciplinary collaboration in the field of product development.

Characterization of the climatology in the Mediterranean Sea

Publisher: name: Universit� degli studi di Genova
Year: 2022

description: The main aim of this research thesis is to find and study new methodologies in order to derive an enhanced knowledge of meteorological conditions and in particular of the sea wave climatology. This applies at first locally and then to the whole extension of the Mediterranean basin. Thanks to the large amount of information stored in databases with high temporal and spatial resolution of time series of wind and wave characteristics, it is possible to improve the knowledge of marine climate. In this way, it is possible to make more accurate assessments that may concern, for example, the planning of offshore operations to be carried out safely, a study of the dispersion of pollutants in case of accident to perform rapid and targeted interventions, an accurate design of "ad hoc" structures to protect coastlines or port areas, proper functioning of measuring instruments or energy production to avoid encountering intense storm events during navigation that can create dangerous situations. Using the hindcast of MeteOcean group at DICCA (Univeristy of Genoa), four main topics have been explored. First, the study of the main tool that allows the definition of wave conditions, namely the energy wave spectrum, is addressed, including the development of the procedure of the reconstruction of the bi-dimensional spectrum, defined in the frequency-direction space. Based on the spectral data, in the second chapter a climatological analysis of the Mediterranean Sea is addressed with the aim of identifying and characterizing the major systems in the spectrum. The study of the climatology of the sea continues by exploring another point of view. In the third chapter, the aim is to select significant climatological scenarios of sea states to effectively summarise the local marine climate, introducing clustering algorithms. Using the capabilities of clustering, the fourth chapter of this research thesis concerns climatology from a spatial point of view. The aim is to divide the Mediterranean basin into climatological areas through the help of k-Means.
The Identity of the ‘Employer’ in Australian Labour Law: Moving Beyond the Unitary Conception of the Employer
Creators: name: Forsyth, Anthony
Publisher: name: Italian Labour Law e-Journal
Year: 2020
Subjects: Unitary employer; Labour hire; Franchising; Supply chains; Collective bargaining

description: This article examines the concept of the ‘employer’ in Australian labour law, showing how the use of this term (and the related concept of ‘employee’) can operate to limit the rights of workers in relation to unfair dismissal, collective bargaining and employment entitlements under the Fair Work Act 2009. It also considers several areas in which rights and obligations are ascribed more broadly, under both the Fair Work Act and workplace health and safety laws. The article then explores various regulatory approaches through which attempts have been made to extend responsibility beyond the unitary conception of the employer, in the context of three specific business models: labour hire, franchising and supply chains. The new forms of regulation adopted in Australia in recent years include labour hire licensing schemes, statutory provisions imposing liability for breaches of minimum employment standards upon franchisors, and regulatory schemes to enhance accountability across sector-specific supply chains. The article concludes with a brief discussion of reforms to bargaining structures which are critical, if business reliance on the unitary concept of the employer is to be meaningfully contested in the Australian setting.

description: This article analyses the switch of the Italian regulatory approach to subcontracting, from the “fordist” model based on a rigid coincidence between the formal employer (holder of the contract) and the user of the work performance, to the new models of production characterised by “organisational fragmentation”. To this purpose, it considers the evolution of the legislative discipline and jurisprudential elaboration concerning the “appalto” contract, the most common Italian commercial contract as for buying labour, goods or services, alongside that of some neighbouring legal instruments.

Joint Employment in the United States

Publisher: name: Italian Labour Law e-Journal

Subjects: Joint employer; Labour law; Employment law; Employment discrimination; Statutory interpretation

description: The joint-employer doctrine in the United States is as fissured as the economy itself. As this paper’s brief survey of the different joint-employer standards used in the U.S. shows, the diverse set of work laws and governing authorities involved in workplace disputes have led to an unpredictable and confusing set of joint-employer standards.Although most of these standards share similarities, there are numerous differences based on the statute involved, whether the dispute is brought under federal or state law, which federal court is hearing the case, and which political party controls a relevant agency. Moreover, thanks in large part to a labor law action against McDonald’s, the joint-employer doctrine has become a politically charged issue, leading several federal agencies recently to change their approach to the question. As a result, businesses and workers cannot be certain that the relevant joint employer standard that exists today will be the same one that applies later. In short, joint employment in the U.S. consists of a complex set of standards that lack clarity and predictability, imposing costs on businesses and workers alike.

description: There is growing observational evidence that disk evolution is stellar-mass dependent. Here, we show that these dependencies extend to the atomic and molecular content of disk atmospheres. We analyze a unique dataset of high-resolution Spitzer/IRS spectra from 8 very low-mass star and brown dwarf disks. We report the first detections of Ne+, H2, CO2, and tentative detections of H2O toward these faint and low-mass disks. Two of our [NeII] 12.81 micron emission lines likely trace the hot (>5,000 K) disk surface irradiated by X-ray photons from the central stellar/sub-stellar object. The H2 S(2) and S(1) fluxes are consistent with arising below the fully or partially ionized surface traced by the [NeII] emission, in gas at about 600 K. We confirm the higher C2H2/HCN flux and column density ratio in brown dwarf disks previously noted from low-resolution IRS spectra. Our high-resolution spectra also show that the HCN/H2O fluxes of brown dwarf disks are on average higher than those of T Tauri disks. Our LTE modeling hints that this difference extends to column density ratios if H2O lines trace warm > 600 K disk gas. These trends suggest that the inner regions of brown dwarf disks have a lower O/C ratio than those of T Tauri disks which may result from a more efficient formation of non-migrating icy planetesimals. A O/C=1, as inferred from our analysis, would have profound implications on the bulk composition of rocky planets that can form around very low-mass stars and brown dwarfs.

description: We consider arbitrary quantum wire networks modelled by finite, noncompact, connected quantum graphs in the presence of an external magnetic field. We find a general formula for the total scattering matrix of the network in terms of its local scattering properties and its metric structure. This is applied to a quantum ring with $N$ external edges. Connecting the external edges of the ring to heat reservoirs, we study the quantum transport on the graph in ambient magnetic field. We consider two types of dynamics on the ring: the free Schrödinger and the free massless Dirac equations. For each case, a detailed study of the thermal noise is performed analytically. Interestingly enough, in presence of a magnetic field, the standard linear Johnson-Nyquist law for the low temperature behaviour of the thermal noise becomes nonlinear. The precise regime of validity of this effect is discussed and a typical signature of the underlying dynamics is observed.

description: In this article, the concept of the employer is analysed for Swedish conditions from a variety of perspectives. The special difficulties that face the private sector are charted, as are the principles of the legal subject in triparty contracts with temporary employment agencies, platform work, and umbrella companies. Found to go hand in hand with the concept of employee, the concept of the employer in the Swedish public sector is now far closer to the standard concept in the private sectordue to the principles of the functional concept of the employer. The concept of the employer in tax law and social security legislation, which have different purposes, differs from labour law.

Reanalysis of the $e^+ e^- \to (D^* \bar D^*)^{\pm} π^{\mp}$ reaction and the claim for the $Z_c (4025)$ resonance

description: In this paper we study the reaction $e^+ e^- \to (D^* \bar D^*)^{\pm} π^{\mp}$ in which the BESIII collaboration has claimed the existence of a $1^+$ resonance, named $Z_c(4025)$, in the $D^*\bar D^*$ invariant mass spectrum with a mass around 4026 MeV and width close to 26 MeV. We determine the $D^*\bar D^*$ invariant mass distribution and find that although the explanation considered by the BESIII collaboration is plausible, there are others which are equally possible, like a $2^+$ resonance or a bound state. Even more, we find that the data can be explained without the existence of a resonance/bound state. In view of the different possible interpretations found for the BESIII data, we try to devise a strategy which could help in identifying the origin of the signal reported by the BESIII collaboration. For this, we study the dependence of the $D^*\bar D^*$ spectrum considering the different options as a function of the total center of mass energy. We arrive to the conclusion that increasing the center of mass energy from 4.26 GeV to 4.6 GeV can be useful to distinguish between a resonance, a bound state or just a pure background as being responsible for the signal found. This information should be useful for future experiments.

description: We derive a set of no-go theorems and yes-go examples for the parity-odd primordial trispectrum of curvature perturbations. We work at tree-level in the decoupling limit of the Effective Field Theory of Inflation and assume scale invariance and a Bunch-Davies vacuum. We show that the parity-odd scalar trispectrum vanishes in the presence of any number of scalar fields with arbitrary mass and any parity-odd scalar correlator vanishes in the presence of any number of spinning fields with massless de Sitter mode functions, in agreement with the findings of Liu, Tong, Wang and Xianyu [1]. The same is true for correlators with an odd number of conformally-coupled external fields. We derive these results using both the (boostless) cosmological bootstrap, in particular the Cosmological Optical Theorem, and explicit perturbative calculations. We then discuss a series of yes-go examples by relaxing the above assumptions one at the time. In particular, we provide explicit results for the parity-odd trispectrum for (i) violations of scale invariance in single-clock inflation, (ii) the modified dispersion relation of the ghost condensate (non-Bunch-Davies vacuum), and (iii) interactions with massive spinning fields. Our results establish the parity-odd trispectrum as an exceptionally sensitive probe of new physics beyond vanilla inflation.
Covid-19 and Self-employment: emergency measures and unsolved challenges

description: The COVID-19 pandemic is having a profound impact on the present world of work and will probably characterize any future debate regarding labour law. The crisis is throwing millions of people across the globe out of employment and high resonance is paid to European governments’ emergency measures to cope with this exogenous catastrophe. Public interventions are driven to protect subordinate workers and their incomes or to support self-employed workers highly affected by lockdown measures. The emergency and temporary measures for this latter group of workers are different from Country to Country, although similar patterns can be identified, varying from the extension of social security coverage to short-term support schemes. Their effectiveness is currently under discussion, alongside some concerns about the future of self-employed workers are still pending.

description: Making user interaction with laboratory equipment more convenient and intuitive should promote experimental work and help researchers to complete their tasks efficiently. The most common form of interaction in current instrumentation is either direct tactile, with buttons and knobs, or interfaced through a computer, using a mouse and keyboard. Scripting is another function typical of smart and automated laboratory equipment, yet users are currently required to learn bespoke programming languages and libraries for individual pieces of equipment. In this paper, we present two open-source, novel and intuitive ways of interacting with and scripting laboratory equipment. We choose the OpenFlexure family of microscopes as our exemplar, due to their open-source nature and smart control system. Firstly, we demonstrate 'OpenFlexure Voice Control' to enable users to control the microscope hands-free. Secondly, we present 'OpenFlexure Blockly' which uses the Blockly Visual Programming Language to enable users to easily create scripts for the microscope, using a drag and drop Web interface. We explain the design choices when developing these tools, and discuss more typical use cases and more general applications.
Early Retirement in the Italian Social Security System: Some Critical Insights

description: This paper examines the age and contributory requirements needed to take retirement in Italy. The focus is on one of the novelties introduced by Decree Law No. 4/2019, namely the possibility to access early retirement through the temporary Quota 100 scheme. This can be done provided that the worker has paid 38 years of contributions and is at least 62 years old by the end of 2021. This exception allows retirement up to 5 years before fulfilling the requirements established under current legislation. Moreover, according to Decree Law No. 4/2019, until 2026 life expectancy growth will not be considered for the purposes of automatic upwards adjustments in pension eligibility requirements. The paper argues that the new measures privilege a specific cohort of people, frustrating the improvements of the Italian pension system over the last three decades. This view is supported by the fact that this temporary relaxation of retirement criteria is not in line with the needs of the Country which emerge through social research and statistical data. Based on demographic and economic analysis, this paper argues that some imbalances question the long-term economic and social sustainability of national social security. The most serious imbalance concerns the disparity between young and older citizens, as the current apparatus favours people who have already reached – or are about to reach – retirement, disadvantaging the following generations.

description: We consider an anisotropic bond percolation model on $\mathbb{Z}^2$, with $\textbf{p}=(p_h,p_v)\in [0,1]^2$, $p_v>p_h$, and declare each horizontal (respectively vertical) edge of $\mathbb{Z}^2$ to be open with probability $p_h$(respectively $p_v$), and otherwise closed, independently of all other edges. Let $x=(x_1,x_2) \in \mathbb{Z}^2$ with $0\prob(\{0\leftrightarrow x'\})$. In this note we give an affirmative answer in the highly supercritical regime.

On the equations of motion of dislocations in quasicrystals

description: In this work we investigate the theory of dynamics of dislocations in quasicrystals. We consider three models: the elastodynamic model of wave type, the elasto-hydrodynamic model, and the elastodynamic model of wave-telegraph type. Similarities and differences between the three models are pointed out and discussed. Using the framework of linear incompatible elastodynamic theory, the equations of motion of dislocations are deduced for these three models. Especially, the equations of motion for the phonon and phason elastic distortion tensors and elastic velocity vectors are derived, where the source fields are given in terms of the phonon and phason dislocation density and dislocation current tensors in analogy to the classical theory of elastodynamics of dislocations. The equations of motion for the displacement fields are also obtained.

The (non/)response of trade unions to the “gig” challenge

Year: 2020
Subjects: Platform workers; Trade unions; Collective agreements; Ireland; Slovenia

description: The advent of platform work has led to deepened debate about the role of trade unions in our contemporary, segmented labour market. One of the crucial questions unions face is how to approach the protection, and organisation, of platform (“gig”) workers. The dilemma about whether to extend employment protection to more of those who work outside of the classical employment relationship can be solved in at least two ways: by changing labour legislation, and/or by extending the scope of collective agreements. This paper analyses two different approaches, from a common law and civil law perspective within the EU, and evaluates their efficacy. The common law perspective is analysed by looking at the case of Ireland, while from the civil law perspective the case of Slovenia is presented. In both countries, trade unions have been struggling to define strategies to approach the issue of the diversification of work relations. On the one hand, unions are wary of eroding the benefits of “employee” status, but on the other, in the context of membership decline, demonstrating relevance to increasing numbers of “non-standard” workers (including “gig workers”) is more important than ever. The paper assesses the union movements’ response in both countries to the “Uberisation” of work.

description: We present numerically calculated, disk--integrated, spectropolarimetric signals of starlight that is reflected by vertically and horizontally inhomogeneous gaseous exoplanets. We include various spatial features that are present on Solar System's gaseous planets: belts and zones, cyclonic spots, and polar hazes, to test whether such features leave traces in the disk--integrated flux and polarization signals. Broadband flux and polarization signals of starlight that is reflected by gaseous exoplanets are calculated using an efficient, adding--doubling radiative transfer code, that fully includes single and multiple scattering and polarization. The planetary model atmospheres are vertically inhomogeneous and can be horizontally inhomogeneous, and contain gas molecules and/or cloud and/or aerosol particles.

Subjects: Covid-19; State of alarm; Telework; Temporary suspension of employment contracts; Temporary reduction in working hours; Force majeure; Dismissals; Social Security benefits

description: The COVID-19 pandemic has had a great impact in Spain. With the purpose of slowing down the spread of the virus and controlling the situation, the Government declared the state of alarm and imposed restrictions to people’s movement and social contact (including temporary confinement of the population at home). Most economic and working activities were temporarily paralysed, leaving apart those considered ‘essential services’ and other exceptions. With the aim of reducing the economic and social impact of such extraordinary circumstances, protecting workers and allowing to resume working activities after the crisis, the Government approved a package of urgent legislation, including a large list of measures in the area of Labour Law and Social Security: among others, promoting telework; facilitating the adaptation of working time to family care needs; favouring the temporary suspension of employment contracts or the reduction of working time due to force majeure or other grounds related to COVID-19, while dismissals were limited; establishing an extraordinary paid leave for workers of undertakings forced to stop their activity; finally, adapting and enhancing unemployment benefits and other forms of social protection. This paper provides a panoramic explanation on this legislation aiming to face the COVID-19 health, economic and employment crisis.
