0015 Die Salomonische Säulenordnung
Creators: name: Hubertus, Günther
Publisher: name: RIHA Journal
Year: 2019

description: As early as 1549, i.e. 50 years before Villalpando's famous Ezechiel commentary was published, Jacques Androuet Ducerceau introduced the Salomonic Order in his Exempla arcuum, a series of engravings in which the Salomonic Order is even presented as a part of a canon of orders. For the first time, the article draws attention to this hitherto neglected early example. The author analyses Ducerceau's canon within the broader context of renaissance theories of architecture, treatises on the columnar order, and conceptions of the origins of good or artful architecture, some of which can be traced back to medieval positions. Furthermore, it is argued that the dismissal of the italic orders in favor of the Salomonic order by Ducerceau and others is inextricably linked to the increasing nationalist tendencies of the renaissance.

Vertical and horizontal integration in public utilities. Evidence from telecom EU operators and Italian water regulatory agencies
Creators: name: BRUNO, Clementina
Publisher: name: Universit� degli studi di Bergamo
Year: 2012

description: The thesis is composed of three chapters.
The first chapter is a review of the literature on economies of vertical and horizontal integration, focused on the public utilities industry. First of all, the definition of economies of scope and the different methods of evaluation are illustrated. Subsequently, the problem of integration connected with the implementation of unbundling (business separation) policies is presented for different categories of utilities (energy, telecommunications, water, multiutilities). Finally, the issue of the quality of service is treated, by examining the indicators used in the mentioned industries, and it is linked to the problem of integration. The second chapter presents an empirical analysis of the economies of vertical integration in fixed telecommunications, which is an issue of large interest but rarely addressed from the empirical perspective. The dataset includes European incumbent firms and the analysis employs a method based on Data Envelopment Analysis. It allows to compute the economies of vertical integration by comparing, for each firm, the efficiency scores obtained with respect to two frontiers, composed of separated and of integrated firms, respectively. The results show the existence of vertical diseconomies, which however become less important when firms concentrate more on ?high-quality? retail services (broadband).
The third chapter is aimed to measure the potential gains from merging Italian water authorities. The dataset contains operational and financial (cost) information on fifty agencies (more than half of the existing authorities). The approach, illustrated in Bogetoft and Wang (2005) and in Bogetoft and Otto (2011), is implemented both in a parametric and in a non-parametric framework. The merger gains are evaluated ex-ante on the basis of the technology as defined by the existing observations. Moreover, the computed potential gain (or loss) is decomposed in technical efficiency, harmony and size effect. By looking at the results, it emerges a relevant potential from recovering technical inefficiency. Moreover, important gains seem to be achievable in terms of size effect, while the output remix (harmony) effect is limited.

description: Context. The anelastic approximation is often adopted in numerical calculation with low Mach number, such as stellar internal convection. This approximation requires frequent global communication, because of an elliptic partial differential equation. Frequent global communication is negative factor for the parallel computing with a large number of CPUs. Aims. The main purpose of this paper is to test the validity of a method that artificially reduces the speed of sound for the compressible fluid equations in the context of stellar internal convection. The reduction of speed of sound allows for larger time steps in spite of low Mach number, while the numerical scheme remains fully explicit and the mathematical system is hyperbolic and thus does not require frequent global communication. Methods. Two and three dimensional compressible hydrodynamic equations are solved numerically. Some statistical quantities of solutions computed with different effective Mach numbers (due to reduction of speed of sound) are compared to test the validity of our approach. Results. Numerical simulations with artificially reduced speed of sound are a valid approach as long as the effective Mach number (based on the reduced speed of sound) remains less than 0.7.

description: In this paper, I have chosen to analyze the importance and role of public debt on economies as a whole. The link between public debt and economic growth is still widely discussed. Although now, less important than during the Eurozone crisis, it does not mean that a high public debt can't be a problem. The financial stability is fundamental to the country's economic groëth and a country with a high debt is most vulnerable when the situation in international markets is not favorable. The public debt makes the economy of a country more vulnerable to an international confidence crisis. The reducing of the international confidence affects the businesses progress, the investments decrease and the increase of the interest rate, decreasing so the economic growth. Let's see how these two indicators affect each other, a low economic growth to the public debt and vice versa; how can we keep public debt under control, how the Central Banks intervene and what the sovereign debt crisis taught us. Key words: public debt, economic growth, economic crisis, financial stability, sovereign state

Creators: name: Konečný, Lubomír
Publisher: name: RIHA Journal
Year: 2019

description: In the first half of the 19th century Georg Franz August de Longueval, Count Buquoy (1781-1851) belonged to the leading, but today not very well known personalities of Czech society, science and culture. He authored approximately thirty pieces of writing on various topics, among them a thirteen-pages booklet Worte der Begeisterung vor der Nacht des Correggio (la Notte del Correggio), issued in Prague in 1825. Buquoy's text deals with the painting known as La Notte, painted in 1527-30 by Antonio Allegri, Il Correggio. From September 1746 in Dresden, it has been extolled as one of the most important Renaissance paintings. Buquoy's text has two parts: The "Vorbemerkung" brings standard information about the picture and explains that the poem which constitutes the second part is meant to echo what was executed by the master's brush strokes ("das am Gemälde in des Meisters Pinselstrichen Vollendete, in Worten [...] anzudeuten"). The author tries to convey here his enthusiasm and religious rapture which Correggio's painting woke up in him. The term "Symbol", the key element in Buquoy's poem, comes into it at its close. This term reflects the discussions on allegory and symbol around and after 1800, and the Count used the concept elaborated by Friedrich Schelling in his Philosophie der Kunst. According to Schelling, not only academic or scholarly analysis, but poetic enthusiasm (Begeisterung) as well plays an essential role in the process of understanding the work of art.

Kolekcjonerzy nawiązywali kontakty ze znawcami i badaczami sztuki, aby tworzyć zbiory najwyższej klasy. Polski arystokrata, Jan Działyński, zaprezentował kolekcję sztuki w specjalnie w tym celu przygotowanej zamkowej sali swojej rodzinnej posiadłości w Kórniku. Ekspozycja jego zbiorów posiada cechy charakterystyczne dla systematycznego i naukowego podejścia do kolekcjonowania, jednak pewne jej elementy nadal świadczą o inspiracji romantycznym zbieractwem narodowych pamiątek, tak popularnym na początku XIX stulecia w Polsce.

Creators: name: Magaš, Lovorka
name: Prelog, Petar
Publisher: name: RIHA Journal
Year: 2019

description: The paper analyses the key aspects of George Grosz's influence on Croatian art between the two World Wars. A number of artists, especially the members of the association Zemlja, considered Grosz to be an author of similar ideological belief, who advocated an active role of art in society. Grosz's standpoints thus indirectly influenced the formation of the overall cultural atmosphere, marked by the polarization of the entire artistic scene. The artist became one of the key reference points and a figure cited by those who exerted a crucial influence on the formation of Croatian artistic scene between the two World Wars – the writer and one of the most prominent intellectuals Miroslav Krleža and visual artists Krsto Hegedušić and Ljubo Babić. The paper also addresses the circumstances regarding the organization of Grosz's solo exhibition in Zagreb in 1932, along with an analysis of the reception of his work among Croatian art critics.

Year: 2019

description: This essay analyses the self-portraits of Jean-Étienne Liotard (1702-1789). Interpreting these objects through the lens of Maurice-Merleau-Ponty's writings on art and vision, I argue that Liotard's self-portraits can be understood as artistic experiments relating to the fundamental phenomenological problem of seeing and representing the lived-body. In making this argument this essay re-evaluates the art-historical tendency to read Liotard's self-portraits biographically as pictures of his unusual life or as tools of self-promotion.

description: The process of liberalization of the Albanian economy throughout the 90's was accompanied by the liberalization of the insurance market, increasing the number of insurance companies with domestic and foreign capital. Since 2011, the process of liberalization of the insurance market was further intensified by the liberalization of motor liability insurance (MTPL), a process that was associated with a fluctuation in the premiums of this type of insurance, causing a lack of stability in the insurance market. The liberalization can lead to market failures and distortions if this liberalization is premature. The main challenge of switching from a regulated tariff system to a liberalized system is to determine the fair pricing of the insurance product. An insurer survives only if he sets appropriate tariffs to cover the risk he has undertaken. This paper describes the liberalization process of MTPL product in the insurance market, its effects as well as the measurement challenges in stabilizing the market. The process of liberalization in the Albanian insurance market should have been more gradual as it was in other countries in the region such as Montenegro, or Bosnia and Herzegovina. The risk-based supervision, the implementation of the Bonus-Malus system as well as the implementation of the European Solvency II directive remain the main challenges but also important factors that could improve the situation in the insurance market in Albania.

description: Large ensembles of heterogeneous oscillators often exhibit collective synchronization as a result of mutual interactions. If the oscillators have distributed natural frequencies and common shear (or nonisochronicity), the transition from incoherence to collective synchronization is known to occur at large enough values of the coupling strength. However, here we demonstrate that shear diversity cannot be counterbalanced by diffusive coupling leading to synchronization. We present the first analytical results for the Kuramoto model with distributed shear, and show that the onset of collective synchronization is impossible if the width of the shear distribution exceeds a precise threshold.
Role of PKC-? in the induction of ferroptosis: a therapeutic target to fight chemoresistance of cancer stem cells
Creators: name: MONTELEONE, LORENZO
Publisher: name: Universit� degli studi di Genova
Year: 2022

description: Cancer stem cells (CSCs) are a small cancer cells population inside the tumor bulk which play a crucial role in tumor recurrence, metastatic dissemination and therapy resistance. CSCs are characterized by high antioxidant defences, such as glutathione (GSH), which by maintaining low production of reactive oxygen species (ROS) confers to CSCs the ability to counteract therapy-induced ROS production favoring the acquisition of resistance. Moreover, GSH is the co?factor of glutathione peroxidase 4 (GPX4), an enzyme able to reduce phospholipid hydroperoxides into corresponding phospholipid alcohols. In this regard, it has been demonstrated that phospholipid peroxidation together with GPX4 inactivation and GSH depletion led to ferroptosis, an iron-dependent non-apoptotc cell death.
CSCs overexpressed xCT, a glutamate-cystine antiport that modulating cysteine availability could limit GSH synthesis. xCT is stabilized at the plasma membrane by CD44, a stem cell marker whose expression is regulated by protein kinase C? (PKC?).
A lot of chemoterapeutics, such as Etoposide, act by increasing ROS levels to eradicate tumor cells.
The aim of this study is to modulate GSH levels in order to sensitize CSCs to pro-oxidant effects induced by Etoposide. Therefore, CSCs were selected from HTLA-230, a human neuroblastoma cell line, and from etoposide?resistant cells (ER-CSCs), and then they were treated with Etoposide alone or in combination with sulfasalazine (SSZ), an xCT inhibitor, or with C2-4, a PKC-? inhibitor.

description: In order to effetively suppress intersymbol interference (ISI) at low complexity, we propose in this paper an approximate maximum likelihood (ML) decision feedback block equalizer (A-ML-DFBE) for doubly selective (frequency-selective, time-selective) fading channels. The proposed equalizer design makes efficient use of the special time-domain representation of the multipath channels through a matched filter, a sliding window, a Gaussian approximation, and a decision feedback. The A-ML-DFBE has the following features: 1) It achieves performance close to maximum likelihood sequence estimation (MLSE), and significantly outperforms the minimum mean square error (MMSE) based detectors; 2) It has substantially lower complexity than the conventional equalizers; 3) It easily realizes the complexity and performance tradeoff by adjusting the length of the sliding window; 4) It has a simple and fixed-length feedback filter. The symbol error rate (SER) is derived to characterize the behaviour of the A-ML-DFBE, and it can also be used to find the key parameters of the proposed equalizer. In addition, we further prove that the A-ML-DFBE obtains full multipath diversity.

Revisiting the Evidence on Capital Openness Using a New Indicator
Creators: name: NUGAWELA, THARINDI RANGITHA GUNARATNA
Publisher: name: Monash University
Year: 2021
Subjects: Economics

description: This thesis explores knowledge in the capital openness domain by introducing new concepts of potential capital openness and the efficiency of capital openness and measuring them. Potential capital openness is proposed as a new index of measuring capital openness. The new indices are applied to revisit the evidence on the macroeconomic trilemma theory, and evidence on a dilemma is revealed. This thesis also explores the income distribution effects of capital openness and reveals that outward capital openness exacerbates inequality while inward capital openness reduces inequality. The extent of the income distribution effect varies with the per-capita income level.

description: The spin torque assisted thermal switching of the single free layer was studied theoretically. Based on the rate equation, we derived the theoretical formulas of the most likely and mean switching currents of the sweep current assisted magnetization switching, and found that the value of the exponent $b$ in the switching rate formula significantly affects the estimation of the retention time of magnetic random access memory. Based on the Fokker-Planck approach, we also showed that the value of $b$ should be two, not unity as argued in the previous works.

Epigenetics in the adult brain: the role of REST in epilepsy
Creators: name: NATALI, GIULIA
Publisher: name: Universit� degli studi di Genova
Year: 2022

description: The Repressor Element 1 Silencing Transcription Factor (REST) is an epigenetic master regulator that plays a crucial role during the life of an individual. REST function was originally described in developmental stages, where it determines neuronal phenotype. However, recent studies showed that REST participates in several processes also in the adult brain, including neuronal plasticity and epileptogenesis. In this regard, the relationship between REST and epilepsy is still controversial and needs further investigation. Here, we studied the role of REST in epilepsy by inducing REST conditional knockout (REST-cKO) specifically in excitatory neurons in vivo. To target the excitatory neuronal population, we cloned the calcium/calmodulin-dependent protein kinase II (CaMKII) minimal promoter upstream of either the Cre recombinase or its inactive form. After assessing the specificity of the promoter?s expression, the aforementioned transgenes were packaged in an engineered adeno-associated virus (PHP.eB) able to cross the blood-brain and blood-cerebrospinal fluid barriers and delivered in the lateral ventricles of 2-month-old RESTflox/flox mice. We then characterized the cognitive phenotype (open field, novel object recognition, and social interaction tests) and the seizure propensity. We show that, with respect to control mice, REST-cKO mice display higher levels of anxiety and short-term memory deficits but have an unaltered social profile. Behavioral evaluation of the susceptibility to epileptic seizures shows that REST-cKO mice are more resistant to pentylenetetrazole (PTZ)-induced kindling, but not to seizures induced by a single PTZ shot, showing a higher survival rate. Overall, these data suggest that the absence of REST induces behavioral alterations and decreases seizure susceptibility. In addition, we developed and characterized genetic tools to specifically delete REST in other central nervous system (CNS) cellular populations (all neurons, inhibitory neurons, and glia) that will help us to draw a more precise and comprehensive picture of the role of REST in the physiopathology of the CNS.

description: Despite its relatively fast development, the insurance sector in Albania suffers from lack of experience, and lack of a database with historical records to make risk assessments feasible and to enable risk premium calculation. Consequently, the newly established companies that operate in the insurance market in Albania cope with difficulties to make accurate calculations of reinsurance premium, i.e. the premium paid by a ceding company to a reinsurer in exchange of the liability assumed by the reinsurer. Given the situation, this research paper aims to provide an introduction to the reinsurance activity and to find an alternative way to the empiric method for the calculation of risk premium for Excess of Loss treaty. First, we will consider the reinsurance function, where we will consider the possible benefits of reinsurance agreement, then we will explore: the different type of reinsurance (Quota Share, Excess of Loss, Surplus); the factors affecting reinsurance needs and finally we will analyse two different methods for calculation of risk premium.

Assuming that $α(\cdot)$ attains its unique minimum at zero and satisfies the regularity condition, we propose a method for construction of observation points (composite dilated design) and find an asymptotics for the integrated mean square error, where a piecewise constant approximation $X_n$ is based on $N(n)\sim n$ observations of $X$. Further, we prove that the suggested approximation rate is optimal, and then show how to find an optimal constant.
0060 "L'idea della architettura universale": Vincenzo Scamozzis Grundlegung einer Theorie der Architektur
Creators: name: Oechslin, Werner
Publisher: name: RIHA Journal
Year: 2012

description: Scamozzi's Idea della architettura universale (1615) is the last architectural treatise endeavoring to provide a comprehensive and all-encompassing presentation of all theoretical and practical issues pertaining to architecture. In doing so, Scamozzi follows Alberti and, most notably, Vitruv who had first defined architecture as a "scientia." Celebrated by his contemporaries for its stunning erudition, Scamozzi's magnum opus was later, on the same grounds, dismissed as incomprehensible. Consequently, translations restricted themselves to the practical parts on building and the obligatory column theory, thus establishing Scamozzi within the canon of authorities, while the other parts of his all-encompassing work were mainly forgotten. This article is dedicated to Scamozzi's undertaking in its entirety: It traces Scamozzi's claims of the universal scope and significance of architecture and the foundation of these claims within a philosophical tradition. Scamozzi emphasizes that architecture, being committed to the principle of causality, qualifies as a science; more precisely, following Aristotelian tradition and the definiton of architecture as "habitus faciendi," he classifies it also as a "scientia fattiva." At the same time Scamozzi is eager, more than his predecessor Daniele Barbaro, to situate architecture beyond the realm of practice. These questions of the relationship of architecture to other arts and sciences are far from being obsolete today; to the contrary, whether we like it or not, they raise the perpetual issue of the self-understanding of architecture and its role and significance within society.

description: Solving cubic equations by a formula that involves only the elementary operations of sum, product, and exponentiation of the coefficients is one of the greatest results in 16th century mathematics. This was achieved by Girolamo Cardano's Ars Magna in 1545.

Still, a deep, substantial difference between the quadratic and the cubic formula exists: while the quadratic formula only involves imaginary numbers when all the solutions are imaginary too, it may happen that the cubic formula contains imaginary numbers, even when the three solutions are anyway all real (and different).
This means that a scholar of the time could stumble upon numerical cubic equations of which he already knew three (real) solutions and the cubic formula of which actually contains square roots of negative numbers.
This will be lately called the ?casus irreducibilis?. Cardano's De Regula Aliza (Basel, 1570) is (at least, partially) meant to try to overcome the problem entailed by it. Its (partial) analysis is the heart of this dissertation.

description: Magnetization, electrical resistivity and specific heat measurements were performed on high-quality single crystalline SmTi$_2$Al$_{20}$ (residual resistivity ratio $\sim$ 40) grown by Al self-flux method. A Kondo-like $\log T$ dependence in the resistivity is observed below 50 K. We discovered a field-insensitive phase transition at $T_{x}$ = 6.5 K and a field-insensitive heavy fermion behavior with the electronic specific heat coefficient $γ$ = 150 mJ/(K$^{2}$ mol). Specific heat analysis reveals that the ground state is a $Γ_{8}$ quartet state and the Sm magnetic dipole moment $m_{\rm Sm}$ ($\sim 0.5 μ_{\rm B}$ at $T \simeq$ 0) orders below $T_{x}$ in spite of the field-insensitive behavior. Possible reasons for the field insensitiveness will be discussed.

description: Nach der Entdeckung der Himmelsscheibe von Nebra entwickelte sich ein jahrelanger Krimi um die Frage nach der Echtheit dieses spektakulären archäologischen Funds. Dass es sich bei der Scheibe um keine Fälschung handelt, sondern tatsächlich um die aus der Bronzezeit stammende älteste konkrete Darstellung kosmischer Phänomene, konnte mithilfe archäometrischer Analysetechniken nachgewiesen werden. Als multidisziplinäres Forschungsgebiet klärt die Archäometrie kulturhistorische Fragen mit naturwissenschaftlichen Mitteln – und nähert sich damit beispielsweise auch Schritt für Schritt der Lösung eines der größten Rätsel der archäologischen Forschung: der Herkunft des bronzezeitlichen Zinns.

Fluctuations assisted stationary entanglement in driven quantum systems

description: We analyze the possible quantum correlations between two coupled dimer systems in the presence of independent losses and driven by a fluctuating field. For the case of the interaction being of a Heisenberg exchange type, we first analytically show the possibility for robust stationary entanglement for realistic values of the dissipation rates and then analyze its robustness as a function of the noise to signal ratio of the pump. We find that for a common fluctuating driving field, a stochastic resonance effect appears as function of the ratio between field strength and noise strength. The effect disappears in the case of uncorrelated or separate pumps. Our result is general and could be applied to different quantum systems ranging from electron spins in solid state, to ions trap technologies and cold atom set ups.

description: The present study aimed to propose a theoretical framework that elucidates the impact of supply chain management (SCM) practices on the competitive advantage and performance of firms while considering the mediating effects of supply chain innovation and total quality management (TQM). This research article employed a descriptive correlational methodology based on a questionnaire, complemented by structural equation modelling. The study involved the participation of 279 individuals, including managers, assistants, and supply chain experts from small and medium-sized enterprises. The study findings suggest that SCM practices significantly influence TQM, supply chain innovation, competitive advantage, and firm performance. Additionally, TQM has a significant effect on supply chain innovation, competitive advantage, and firm performance. Similarly, supply chain innovation has a positive and significant impact on competitive advantage and firm performance. Furthermore, the positive and significant mediating role of supply chain innovation and TQM in the effect of SCM practices on competitive advantage and firm performance was observed. Therefore, it can be concluded that SCM practices enhance firm performance and competitive advantage through the improvement of supply chain innovation and TQM.

CNO and F abundances in the globular cluster M22 (NGC 6656)

description: Recent studies have confirmed the long standing suspicion that M22 shares a metallicity spread and complex chemical enrichment history similar to that observed in Omega Cen. M22 is among the most massive Galactic globular clusters and its colour-magnitude diagram and chemical abundances reveal the existence of sub-populations. To further constrain the chemical diversity of M22, necessary to interpret its nucleosynthetic history, we seek to measure relative abundance ratios of key elements (carbon, nitrogen, oxygen, and fluorine) best studied, or only available, using high-resolution spectra at infrared wavelengths. High-resolution (R = 50,000) and high S/N infrared spectra were acquired of nine red giant stars with Phoenix at the Gemini-South telescope. Chemical abundances were calculated through a standard 1D local thermodynamic equilibrium analysis using Kurucz model atmospheres. We derive [Fe/H] = -1.87 to -1.44, confirming at infrared wavelengths that M22 does present a [Fe/H] spread. We also find large C and N abundance spreads, which confirm previous results in the literature but based on a smaller sample. Our results show a spread in A(C+N+O) of ~ 0.7 dex. Similar to mono-metallic GCs, M22 presents a strong [Na/Fe]-[O/Fe] anticorrelation as derived from Na and CO lines in the K band. For the first time we recover F abundances in M22 and find that it exhibits a 0.6 dex variation. We find tentative evidence for a flatter A(F)-A(O) relation compared to higher metallicity GCs. Our study confirms and expands upon the chemical diversity seen in this complex stellar system. All elements studied to date show large abundance spreads which require contributions from both massive and low mass stars.

description: Using the Southeastern Association for Research in Astronomy 0.6 meter telescope located at Cerro Tololo, we searched for variable stars in the southern globular cluster NGC 6584. We obtained images during 8 nights between 28 May and 6 July of 2011. After processing the images, we used the image subtraction package ISIS developed by Alard (2000)to search for the variable stars. We identified a total of 69 variable stars in our 10x10 arcmin^2 field, including 43 variables cataloged by Millis & Liller (1980) and 26 hereto unknown variables. In total, we classified 46 of the variables as type RRab, with a mean period of 0.56776 days, 15 as type RRc with a mean period of 0.30886 days, perhaps one lower amplitude type RRe, with a period of 0.26482 days, 4 eclipsing binaries, and 3 long period (P > 2 days) variable stars. As many as 15 of the RRab Lyrae stars exhibited the Blazhko Effect. Furthermore, the mean periods of the RR Lyrae types, the exhibited period/amplitude relationship, and the ratio of N_c/(N_ab+N_c) of 0.25 are consistent with an Oosterhoff Type I cluster. Here we present refined periods, V-band light curves, and classifications for each of the 69 variables, as well as a color-magnitude diagram of the cluster.

description: Few-body physics has played a prominent role in atomic, molecular and nuclear physics since the early days of quantum mechanics. It is now possible---thanks to tremendous progress in cooling, trapping, and manipulating ultracold samples---to experimentally study few-body phenomena in trapped atomic and molecular systems with unprecedented control. This review summarizes recent studies of few-body phenomena in trapped atomic and molecular gases, with an emphasis on small trapped systems. We start by introducing the free-space scattering properties and then investigate what happens when two particles, bosons or fermions, are placed in an external confinement. Next, various three-body systems are treated analytically in limiting cases. Our current understanding of larger two-component Fermi systems and Bose systems is reviewed, and connections with the corresponding bulk systems are established. Lastly, future prospects and challenges are discussed. Throughout this review, commonalities with other systems such as nuclei or quantum dots are highlighted.
