description: We carefully analyse the use of the effective action in dynamical problems, in particular the conditions under which the equation $\frac{δ\Ga} {δϕ}=0$ can be used as a quantum equation of motion, and the relation between the asymptotic states involved in the definition of $\Ga$ and the initial state of the system. By considering the quantum mechanical example of a double-well potential, where we can get exact results for the time evolution of the system, we show that an approximation to the effective potential in the quantum equation of motion that correctly describes the dynamical evolution of the system is obtained with the help of the wilsonian RG equation (already at the lowest order of the derivative expansion), while the commonly used one-loop effective potential fails to reproduce the exact results.

description: Aims. We investigate the physical and chemical conditions of molecular gas in the circumnuclear disk (CND) region of NGC 1068. Methods. We carried out a spectral line survey with the IRAM 30m telescope toward the center of NGC 1068 and mainly focused on the 2 mm band with a frequency coverage of 160.7-168.6 GHz and 176.5-184.3 GHz. Results. Fifteen lines are detected in NGC 1068, eight of which are new detections for this galaxy. We derive the rotation temperatures and column densities of fourteen molecular species. Conclusions. Based on the [HCO+ (2 - 1)]/[HOC+ (2 - 1)] ratio, we obtain a high ionization degree in the CND of NGC 1068. It is found that HC3N is concentrated in the east knot, while 13CCH, CH3CN, SO, HOC+, CS, CH3CCH, and H2CO are concentrated in the west knot. Compared to the star-forming galaxies M 82 and NGC 253, the chemistry of NGC 1068 might be less strongly affected by the UV radiation field, and its kinetic temperature might be lower.

description: In this paper we calculate the Italian Cities Sustainable Development Goals (SDGs) Composite Index potentially useful for policy analysis and dissemination of sustainable development at local level in Italy. Structured into several dimensions representing 16 out of 17 SDGs adopted by the United Nations at the end of September 2015, the index merges 53 available economic, social and environmental elementary indicators into a single composite dimension, highlighting a geographical and demographic heterogeneity within the country. By using the Spectral Value Decomposition technique, the index offers an urban focus of sustainability, showing some differences among the goals and the cities of Italy. Finally, it identifies the Goal concerning quality education and decent work and economic growth as the main key Goals for sustainability.

Balabeesa Parade!

description: The Coptic diaspora in Canada has long been grappling with issues of identity in our newly adopted spaces. Many feel retrofitted spaces are not ‘Coptic enough,’ that it’s not the way it was back home. Attempting to achieve this sense typically manifests in shipping art and trinkets from Egypt to display in our new spaces, or merely copying typologies into new build churches. However, this prompts further questions regarding the authenticity of the work and identity of the diasporic people, and lacks consideration of the contexts they currently live in. What has proven to be truly enduring and viscerally alive are the traditions which cross borders with us. These traditions, whether religious or secular, mitigate better cultural preservation than any stagnant artifacts, as they shift with the realities of those practicing them. This project reimagines the revival of a since forgotten Epiphany parade, once widely celebrated throughout towns in Egypt, now lost in time, to be rekindled by the Canadian diasporic community here in Vancouver, British Columbia. In this space, culture becomes dynamic and entangled with all those participating.

description: Nuclear is considered as a valuable option for the decarbonization of the power generation, as it is a no-carbon, yet commercially consolidated technology. However, its real prospects are uncertain: if some countries, especially in the non-OECD area, have been extensively investing in nuclear, many OECD countries, which host the vast majority of operational reactors worldwide, feature old fleets which will not be replaced, as phase-out policies are being implemented. Research scenarios often consider polarized conditions based on either a global unconstrained nuclear development or a generalized phase-out. The main aim of this work is instead to explore the techno-economic implications of policy-relevant scenarios, designed on the actual nuclear prospects in the world regions, i.e. mainly differentiating policy constraints between the OECD and the non-OECD regions. The analysis, conducted via the Integrated Assessment Model WITCH, shows that nuclear generation constantly grows over the century, even if in general the nuclear share in the electricity mix does not significantly change over time, both at a global and at a European level. Over time, and especially if constraints are applied to nuclear deployment, the nuclear contribution is compensated by renewables (mainly wind and solar PV) and, to a lower extent, by CCS (only marginally in the EU). The policy costs related to the nuclear phase-out are not particularly high (0.4% additional global GDP loss with respect to the unconstrained policy scenario), as they are almost completely compensated by innovation and technology benefits in renewables and energy efficiency. Phase-out policies applied only to the OECD regions do not entail any additional policy costs, while non-OECD regions marginally benefit from lower uranium prices. A sudden shutdown of nuclear reactors in the OECD regions results in a doubling of these losses and gains.

description: The VODAN Brazil (VODAN BR) project aims at establishing, at the national level, the VODAN federated data infrastructure to support the capture and use of data, not only during this Covid-19 pandemic but also on future disease outbreaks. This poster describes the first steps for collecting and treating anonymized patients data from Covid-19 cases, following the WHO standard form, initially from two public hospitals. VODAN BR is establishing an IT architecture to manage these data, addressing practical challenges from the hospital partners, such as collecting data from the current hospital information systems and integrating these data with semantic-oriented CRF systems that are based on the WHO semantic model developed by VODAN. This flexible architecture addresses these challenges through: (1) an extraction and collection strategy for the heterogeneous systems; (2) a staging relational database adherent to the WHO semantic model; (3) a workflow-based support for the FAIRification process through the ETL4LOD tool; (4) data repositories enriched with graph database technologies and FAIR Data Points.

Agent for Autonomous Driving based on Simulation Theories
Creators: name: Donà, Riccardo
Publisher: name: Università degli studi di Trento
Year: 2021

description: The field of automated vehicle demands outstanding reliability figures to be matched by the artificially driving agents. The software architectures commonly used originate from decades of automation engineering, when robots operated only in confined environments on predefined tasks. On the other hand, autonomous driving represents an “into the wild” application for robotics. The architectures embraced until now may not be sufficiently robust to comply with such an ambitious goal. This research activity proposes a bio-inspired sensorimotor architecture for cognitive robots that addresses the lack of autonomy inherent to the rules-based paradigm. The new architecture finds its realization in an agent for autonomous driving named “Co-driver”. The Agent synthesis was extensively inspired by biological principles that contribute to give the Co-driver some cognitive abilities. Worth to be mentioned are the “simulation hypothesis of cognition” and the “affordance competition hypothesis”. The former is mainly concerned with how the Agent builds its driving skills, whereas the latter yields an interpretable agent notwithstanding the complex behaviors produced. Throughout the essay, the Agent is explained in detail, together with the bottom-up learning framework adopted. Overall, the research effort bore an effectively performing autonomous driving agent whose underlying architecture provides considerable adaptation capability. The thesis also discusses the aspects related to the implementation of the proposed ideas into a versatile software that supports both simulation environments and real vehicle platforms. The step-by-step explanation of the Co-driver is made up of theoretical considerations supported by working simulation examples, some of which are also released open-source to the research community as a driving benchmark. Eventually, guidelines are given for future research activities that may originate from the Agent and the hierarchical training framework devised. First and foremost, the exploitation of the hierarchical training framework to discover optimized longer-term driving policies.
On the Interaction between Small Decay, Agent Heterogeneity and Diameter of Minimal Strict Nash Networks in Two-way Flow Model: A Note

description: In this note, I study the roles of value heterogeneity - i.e., agents are heterogeneous in terms of values of nonrival information thay they possessed - in determining the shapes of two-way flow Strict Nash networks when small amount of decay is present. I do so by extending the two-way flow network with small decay of De Jaegher and Kamphorst (J ECON BEHAV ORGAN, 2015). Results of this extension shows that the effects of value heterogeneity on Strict Nash networks, when small decay is present, largely resemble the effects of heterogeneity in link formation cost - without decay - found in the literature. Another surprising finding is that value heterogeneity can extend the diameters of Strict Nash networks without changing any other properties. In the discussion section of this note, I relate this finding to two well-known concepts in the studies of social networks - small world and preferential attachment.
Essays on Migration and Gender
Creators: name: Crocè, Clementina
Publisher: name: Università degli studi di Trento
Year: 2021

description: This thesis investigates the interdependence between migration and gender dynamics, with a focus on low- and middle-income countries. The first chapter concerns intra-household bargaining and migration decision-making: considering that the decision to migrate is likely to be made within the family, the bargaining powers of household members may shape the result of the decision-making process. Given that there is evidence of women’s altruistic behaviours towards their children, I investigate how women’s bargaining power affects the decisions about the individual migrations of their young offspring, who may benefit from the change in location. A collective model of migration decision-making and an empirical analysis regarding the context of Mexico are presented. This analysis sheds the light on how empowerment may be beneficial not only to women themselves but also to their children, and suggests that policies intending to improve women’s position within the household and the whole society should also acknowledge these positive spillover effects. The second chapter regards the uncertainty over health status and the gendered determinants of migration. While several studies show a relationship between migration and health, migration selection in terms of health conditions is relatively under-investigated, as regards the context of Sub-Saharan African countries. Using panel data from a survey on young women and men living in Malawi, I assess the impact of randomised HIV testing on long- and short-term migrations, and I find that becoming certain of being HIV-negative affects the probability of both types of movements, only for women. This impact evaluation indicates that HIV testing may have gender-specific unintended consequences, which should be considered. Finally, the third chapter evaluates the impact of a randomised intervention, aiming to promote child development through improvements in parenting skills, on the empowerment of women in Bangladesh. Results show that the programme increases women’s autonomy and reduces their exclusion from decision-making processes: these effects do not concern only child-related decisions – consistent with the type of training that women in the treatment group receive – but also decisions about the allocation of resources. The empowerment effect regards only women whose partner has never migrated before the baseline, thus suggesting the existence of a relationship between women’s decision-making power and men’s migration – as found in previous studies.

description: Lead-free double perovskite materials (viz. Cs$_2$AgInCl$_6$) are being explored as stable and non-toxic alternatives of lead halide perovskites. In order to expand the optical response of Cs$_2$AgInCl$_6$ in visible region, we report here the stability, electronic structure and optical properties of Cs$_2$AgInCl$_6$ by sublattice mixing of various elements. Here, we have employed %high-throughput screening using a hierarchical first-principles based approach starting from density functional theory (DFT) with appropriate exchange-correlation functionals to beyond DFT methods under the framework of many body perturbation theory (viz. G$_0$W$_0$@HSE06). We have started with 32 primary set of combinations of metals M(I), M(II), M(III) and halogen X at Ag/In and Cl site, respectively, where concentration of each set is varied to build a database of nearly 140 combinations. The most suitable mixed sublattices are identified to engineer the band gap of Cs$_2$AgInCl$_6$ to have its application in optoelectronic devices under visible light.

description: Background: Caregivers play a central role in post-stroke patients care. However, the role of and problems managed by caregivers have not been widely studied, particularly in Indonesia. This study aims to explore the roles and problems of caregivers in post- stroke patients’ care. Method: This was a qualitative study. Caregivers of post-stroke patients from the homecare clinic of Dr Sardjito General Hospital were purposely selected during January 2017 to June 2018. Focus group discussions were conducted to explore the roles and problems of caregiving. Results: Themes related to caregivers’ roles were: connecting patients with medical personnel and other family members, maintaining patients’ health conditions by fulfilling basic needs and assisting rehabilitation, as well as maintaining patients’ psychological conditions by encouraging conversation, telling jokes, or recreation. On the other hand, themes related to caregivers’ problems were: lack of knowledge caused by education inadequacy, underappreciated and unconcerned family, suboptimal service including limited physiotherapy and pharmacy resource, and unthorough administration, lack of communication, physical limitations and burnout, as well as uncooperative patients. Conclusions: Caregivers play essential roles as communicators and help to maintain patient's health conditions. Common problems are related to a lack of knowledge about strokes and a lack of attention from family. Understanding the roles and problems of caregivers may help facilitate better management and increase the quality of life for both patients and their caregivers.

description: Detecting the change of a cosmological object's redshift due to the time evolution of the Universal expansion rate is an ambitious experiment that will be attempted with future telescope facilities. In this paper, we describe the ACCELERATION programme, which aims to study the properties of the most underdense regions of the Universe. One of the highlight goals of this programme is to prepare for the redshift drift measurement. Using the EAGLE cosmological hydrodynamic simulations, we estimate the peculiar acceleration of gas in galaxies and in the Lya forest. We find that star-forming 'cold neutral gas' exhibits large peculiar acceleration due to the high local density of baryons near star-forming regions. We conclude that absorption by cold neutral gas is unlikely to yield a detection of the cosmological redshift drift. On the other hand, we find that the peculiar accelerations of Lya forest absorbers are more than an order of magnitude below the expected cosmological signal. We also highlight that the numerous low H I column density systems display lower peculiar acceleration. Finally, we propose a new 'Lya cell' technique that applies a small correction to the wavelength calibration to secure a relative measurement of the cosmic drift between two unrelated cosmological sources at different redshifts. For suitable combinations of absorption lines, the cosmological signal can be more than doubled, while the affect of the observer peculiar acceleration is mitigated. Using current data of four suitable Lya cells, we infer a limit on the cosmological redshift drift to be dv/dt_obs < 65 m/s/year (2 sigma).

 Type species. Melita subchelata Schellenberg, 1925.
 Diagnosis. Antenna 1 longer than antenna 2. Maxilla 1 inner plate long, narrow, tapering distally, with 2 well developed apical plumose setae. Maxilla 2 inner plate with oblique setal row. Gnathopod 2 male, significantly unequal in size, palm in larger acute, female equal in size. Pereopods 5–7 dactylar ungues without accessory spines. Pereopod 7 basis sexual dimorphism unknown. Pleonites dorsally serrate. Uropod 3 inner ramus scalelike; outer ramus 4 to 5 x longer than wide, 2-articulate. Telson deeply cleft, lobes tapering distally to an acute point.
 Included species. Verdeia includes 2 species: V. grandimana (Chevreux, 1908) and V. subchelata (Schellenberg, 1925).
 Remarks. Verdeia is part of the Megamoera group of melitids and appears to be a sister taxon of Dulichiella. The shapes of the lateral cephalic lobes, the robust setae along the posterior margin of antenna 1 peduncular article 1, the slender mandibular palps with a long third article, the long, slender shape of the inner plates on maxilla 1, the asymmetrical and enlarged male second gnathopods, the shapes and structure of the female second gnathopods, the shape of coxae 4, the shapes of the basis of pereopods 5–7, the third uropods and the telsons are all similar.
 Verdeia differs from Dulichiella in not having setae on the anteroventral corner of the head, in not having posteroventral notches on the anterior coxae, in having a different structure to the distolateral crown and palm on the propodus of male gnathopod 2, in having an acute rather than obtuse palmar angle on gnathopod 2, and in not having accessory spines on the dactyli of pereopods 5–7.

Our analysis takes into account all possible uncertainties, such as statistical, finite size and quenching errors when performing the chiral and continuum extrapolations and we have indications that our signal is separated from scattering states. The lowest mass that we find in the I^P=0^- channel is in complete agreement with the experimental value of the Θ^+ mass. On the other hand, the lowest mass state in the opposite parity I^P=0^+ channel is much higher. Our findings suggests that the parity of the Θ^+ is negative.

description: The high potential of integrating renewable energy resources into the power system using voltage source converters (VSCs) raises some system stability issues due to the absence of inertia in VSCs. The virtual synchronous machine (VSM) control concept is consequently introduced to mimic the properties of traditional synchronous machines. Several VSM control algorithms with different structures have been introduced in literature. However, since all VSM controllers are co-linked as an active and reactive power control, it is difficult to achieve a unity power factor from a VSC-based VSM, a feature which is more likely favoured in a multi-terminal HVDC systems. This paper proposes a new way to implement the VSM control concept which offers several advantages. The proposed hybrid virtual synchronous machine (HVSM) provides a fully decoupled independent active and reactive power control. This paper further presents a comparative comprehensive study of the proposed HVSM with the existing VSM in literature. The system has been validated and investigated in a time-domain simulation environment, namely PSCAD/EMTDC. The simulation results show significant results that will further extend the field of virtual synchronous machine research.

description: Recently proposed nonlocal and nonperturbative late time behavior of the heat kernel is generalized to curved spacetimes. Heat kernel trace asymptotics is dominated by two terms one of which represents a trivial covariantization of the flat-space result and another one is given by the Gibbons-Hawking integral over asymptotically-flat infinity. Nonlocal terms of the effective action generated by this asymptotics might underly long- distance modifications of the Einstein theory motivated by the cosmological constant problem. New mechanisms of the cosmological constant induced by infrared effects of matter and graviton loops are briefly discussed.

title: Evaluation of ClearSpeed Accelerators for HPC
Creators: name: Kozin, Igor
Publisher: name: STFC
Year: 2009

description: ClearSpeed Accelerator Tera-scale System (CATS) has been evaluated in an HPC setup by running a number of benchmarks and real applications. Our tests demonstrated a significant advantage of the technology in terms of performance per Watt and density of compute power over the current commodity offerings. However this needs to be set against considerations of ?total cost of ownership? and the real benefit of the ClearSpeed acceleration technology currently appears to be the ability to deliver greater performance in HPC data centres which are limited by the power and/or space available rather than purchase and running costs.
Eliashberg Theory: a short review

Subjects: subject: Superconductivity (cond-mat.supr-con)
subject: FOS: Physical sciences

description: Eliashberg theory is a theory of superconductivity that describes the role of phonons in providing the attractive interaction between two electrons. Phonon dynamics are taken into account, thus giving rise to retardation effects that impact the electrons, in the form of a frequency-dependent electron self-energy. In the superconducting state, this means that the order parameter, generally considered to be a static quantity in the Bardeen-Cooper-Schrieffer (BCS) theory, also becomes frequency-dependent. Here we review the finite temperature formulation of Eliashberg theory, both on the imaginary and real frequency axis, and briefly display some examples of the consequences of a dynamical, as opposed to static, interaction. Along the way we point out where further work is required, concerning the validity of some of the assumptions used.

description: Since the Polish EU accession each EU programming period has brought changes in CAP and the level of funds assigned for Poland. There is a wide range of research publications presenting the structure of Common Agricultural Policy support for the Polish agriculture and rural areas. Yet, most of them cover only one programming period or concentrate on structural changes in agriculture and rural areas informing about the level of support only as a starting point for further analyses. The aim of the paper is to assess the actual objectives of the CAP implementation in Poland. These objectives are reconstructed by analysing the level of support allocated to different types of farms and farming regions and the types of instruments applied to transfer these funds. The analysis is conducted based on the national statistical data concerning agriculture including the last two censuses – in 2002 and 2010 as well as the data on the CAP transfers made by the Agency for Restructuring and Modernisation of Agriculture during the period 2004-2013. Some comparisons use also Polish FADN database. The results show that generally the key beneficiaries are the smallest and the largest farms. However, there are significant differences in the division between winners and losers when specific policy instruments are analysed.
Leibniz algebras, Lie racks, and digroups

description: The "coquecigrue" problem for Leibniz algebras is that of finding an appropriate generalization of Lie's third theorem, that is, of finding a generalization of the notion of group such that Leibniz algebras are the corresponding tangent algebra structures. The difficulty is determining exactly what properties this generalization should have. Here we show that \emph{Lie racks}, smooth left distributive structures, have Leibniz algebra structures on their tangent spaces at certain distinguished points. One way of producing racks is by conjugation in \emph{digroups}, a generalization of group which is essentially due to Loday. Using semigroup theory, we show that every digroup is a product of a group and a trivial digroup. We partially solve the coquecigrue problem by showing that to each Leibniz algebra that splits over its ideal generated by squares, there exists a special type of Lie digroup with tangent algebra isomorphic to the given Leibniz algebra. The general coquecigrue problem remains open, but Lie racks seem to be a promising direction.

description: Competitiveness has become a key issue on international markets since it can be considered as the major source of export development. A country that utilizes the best its resources within its agricultural sector may benefit from comparative advantage on international agricultural markets. Due to the Deep and Comprehensive Free Trade Agreement signed recently between Moldova and European Union, it is of vital importance for local agri-food products to be competitive on the EU market and to assess the potential gains of the increased demand. Moldova’s share on agri-food exports is still large, but various changes occurred in the total value and the geographical structure of trade flows during the analyzed period. The aim of this research is to analyze the changes that happened in the pattern trade flows and to evaluate the consequences and potential benefits of DCFTA on agri-food exports of Moldova. In the given research data from the National Bureau of Statistics for the period 2001-2012 will be used. The analysis of competitiveness will be carried out by assessing trade indices of intra and inter industrial trade (RTA, GL).

description: We have computed correlation functions for nucleons and extracted the masses for positive- and negative-parities. Use of group theory plays an important role in obtaining sources that have good overlap to higher spin states and minimum contamination from unwanted states. In the simulation three distinct sources and corresponding sinks that transform according to the $G_1$ irreducible representations are tested and used to form matrices of correlation functions. Diagonalizations give us clear mass splittings between low-lying states and excited states for both parities.

Simulations of Normal Spiral Galaxies
Creators: name: Bottema, Roelof
Publisher: name: arXiv
Year: 2003
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Results are presented of numerical simulations of normal isolated late type spiral galaxies. Specifically the galaxy NGC 628 is used as a template. The method employs a TREESPH code including stellar particles, gas particles, cooling and heating of the gas, star formation according to a Jeans criterion, and Supernova feedback. A regular spiral disc can be generated as an equilibrium situation of two opposing actions. On the one hand cooling and dissipation of the gas, on the other hand gas heating by the FUV field of young stars and SN mechanical forcing. The disc exhibits small and medium scale spiral structure of which the multiplicity increases as a function of radius. The theory of swing amplification can explain, both qualitatively and quantitatively, the emerging spiral structure. In addition, swing amplification predicts that the existence of a grand design m=2 spiral is only possible if the disc is massive. The simulations show that the galaxy is then unstable to bar formation. A general criterion is derived for the transition between bar stable and unstable, depending on disc mass contribution and on disc thickness. It seems that bar stability hardly depends on the presence of gas. A detailed quantitative analysis is made of the emerging spiral structure and a comparison is made with observations. That demonstrates that the structure of the numerical isolated galaxies is not as strong and has a larger multiplicity compared to the structure of some exemplary real galaxies. It is argued that a grand design can only be generated by a central bar or by tidal forces resulting from an encounter with another galaxy.

description: This study deals with the differentiation of Czech countryside in its relation to the delineation of countryside itself. Ongoing changes in the countryside bring about its increased differentiation. This trend also applies to Czech countryside, which can be characterized as highly differentiated. This implies a need to delineate countryside itself, as well as its individual types. The delineation of countryside is a long term focus of the OECD, whose methodology is employed in this study. Its scale, however, has been adjusted to the level of districts (LAU 1). This study attempts to shed some light on the existing differentiation and diversity of the Czech countryside. For the individual categories of the OECD typology, we observed selected socio-economic indicators (net migration, primary sector employment, educational structure and unemployment rate) and analysed the differentiation of these characteristics across the sets of municipalities. The observation clearly indicates that small municipalities in rural regions display worse socio-economic characteristics. In terms of the selected indicators, the analysis also reveals a significant differentiation caused by the regions’ geographic position.

description: We present analytic expressions for the $s$-parametrized currents on the sphere for both unitary and dissipative evolutions. We examine the spatial distribution of the flow generated by these currents for quadratic Hamiltonians. The results are applied for the study of the quantum dissipative dynamics of the time-honored Kerr and Lipkin models, exploring the appearance of the semiclassical limit in stable, unstable and tunnelling regimes.
