Integrable S matrix, mirror TBA and spectrum for the stringy AdS3×S3×S3×S1\text{AdS}_{3}\times\text{S}^3\times\text{S}^3\times\text{S}^1 WZW model

We compute the tree-level bosonic S matrix in light-cone gauge for superstrings on pure-NSNS $\text{AdS}_{3}\times\text{S}^3\times\text{S}^3\times\text{S}^1$. We show that it is proportional to the identity and that it takes the same form as for $\text{AdS}_{3} \times \text{S}^3\times\text{T}^4$ and for flat space. Based on this, we make a conjecture for the exact worldsheet S matrix and derive the mirror thermodynamic Bethe ansatz (TBA) equations describing the spectrum. Despite a non-trivial vacuum energy, they can be solved in closed form and coincide with a simple set of Bethe ansatz equations - again much like $\text{AdS}_{3}\times\text{S}^3\times\text{T}^4$ and flat space. This suggests that the model may have an integrable spin-chain interpretation. Finally, as a check of our proposal, we compute the spectrum from the worldsheet CFT in the case of highest-weight representations of the underlying Ka\v{c}-Moody algebras, and show that the mirror-TBA prediction matches it on the nose.Comment: 38 pages, Version accepted for publication in JHE

Studio e analisi della tecnica del Problem Solving e sua applicazione in una multinazionale del settore meccanico

Questo lavoro di tesi è il risultato di un periodo di partecipazione ad un progetto con il Consorzio Universitario Quinn svolto presso l’azienda Rotork Fluid System di Lucca. Tale progetto richiedeva una classica analisi del clima e ri-motivazione delle risorse umane. Il progetto, nonostante le premesse iniziali, ha assunto una piega differente. Infatti, in fase di progettazione, si è deciso che non sarebbe stato efficace un intervento motivazionale classico, poiché solitamente gli effetti generati sono di breve durata. Il progetto si è articolato in due fasi: durante la prima sono stati svolti degli incontri, Workshop, con i 15 dipendenti dell’Unità Organizzativa Inside Sales allo scopo di individuare i problemi riscontrati dagli stessi durante lo svolgimento del loro lavoro, nella seconda fase è stata svolta l’analisi dei problemi emersi e l’individuazione delle strategie più idonee per la messa in pratica delle soluzioni. In parallelo con i manager della U.O. sono state fatte alcune riunioni allo scopo di valutare la necessità di un miglioramento organizzativo attraverso un processo di riconfigurazione interna. È stata quindi proposta una metodologia generale di Problem Solving, che ha portato come risultato proposte di risoluzioni concrete ed applicabili nella realtà aziendale. This thesis is the result of a collaborative project with Consorzio Universitario Quinn for Rotork Fluid System, in Lucca. This project required a classic analysis of the climate and re-motivation of human resources. The project, although the initial premises, took a different turn. Indeed, in the planning phase, it was decided that a classic motivational intervent would not have been effective, because the effects usually wear out in the short term. The project was carried out in two phases: in the first, 15 employees of Inside Sales gathered in Workshops, in order to identify the problems encountered during the work. In the second stage the issues raised have been analyzed and the best strategies, to practice the solutions, have been identified. Meanwhile, some meetings were made with the managers of the U.O., with the aim of assessing the need for organizational through a process of internal reconfiguration. A general methodology for problem solving was set forth and it has resulted in proposals for concrete solutions for the company.

In conducting the research, descriptive-qualitative method is employed. The techniques utilized by this research are observation, interview, and documentation. This research uses a recorder, observation checklist sheets, references checklist sheets, and interview guidelines as the research instruments. The findings cover the TNgRR history at the Kuru Setra Hermitage motivated by a belief of the ancestors. It is said that on 11, 12, 13, 14 Rabi-ul-Awal month4) the angels are praying to Allah in heaven. Thus, those become the perfect days to pray to Allah and to purify the minds. The ritual is started by art performances followed by a sermon, dhikr, and mass bathing by using water from seven wells/springs. The findings also cover the esthetic value of the TNgRR comprised of pure value, such as a) the decorations, used in the ritual (e.g. janur kuning, flowers, wayang, flags, four-colored fabrics) to create harmony and beauty; b) the clothing, where the esthetic value can be seen from the color of the clothing that is black representing braveness ; c) the offerings, where the esthetic value can be seen from the offerings placement order to create beauty as well as to cherish the ancestors; d) the art performances, which purposes is to complement the TNgRR, where the esthetic value can be seen from the types of art performed. In addition, the value is increased through the involvement of human beings, nature, animals, etc. In order to maintain the tradition, the result of this research is implemented as a cultural reading text for senior high school students

About the Strength of Proof Statements in Judicial Decision: The Constitutive Leap

Este ensayo propone una crítica a la tesis pragmática según la cual los enunciados probatorios de las decisiones judiciales del tipo «está probado que p» poseen fuerza descriptiva siendo, por tanto, verdaderos o falsos. En primer lugar, se dilucida la noción de fuerza pragmática y se estipula la distinción entre enunciados descriptivos y normativos. Luego, se muestra que en los contextos procedimentales donde el sistema de valoración de la prueba es el conocido como Sana Crítica Racional, los enunciados probatorios, por una parte, expresan un juicio valorativo de quien los profiere y, por la otra, fungen de razones prácticas dirigidas a justificar una acción del mismo emisor, a saber: la aceptación del enunciado fáctico como premisa de la decisión judicial. Estas circunstancias, se sostiene, muestran que enunciados probatorios proferidos en esos contextos poseen fuerza normativa postulándose provisoriamente su carácter constitutivo.This essay proposes a criticism to the pragmatic thesis according to which, the proof statements of judicial decision of the kind «it is proven that p» have descriptive strength, being, therefore, true or false. First of all, the notion of pragmatic strength is enlightened and the distinction between descriptive statements and normative statements is provided. Then, it is shown that in judicial process contexts where the proof evaluation system is the well-known as principle of «free proof», the proof statements, in one hand express a judgment of value of the one that utters them, and in the other hand, they work as practical reasons aiming to justify an action of the decision-maker by himself, namely: the acceptation of the factual statement as a premise of the judicial decision. This circumstances, it is upheld, demonstrate that proof statements issued in this kind of contexts bear a normative strength, postulating temporarily their constitutive character

Breast cancer or metastasis? An unusual case of metastatic malignant pleural mesothelioma to the breast

Background: Metastases to the breast from extramammary malignancies are very rare, and ruling out the diagnosis of primary breast tumor is important in order to decide on clinical management and predict prognosis. Case presentation: Clinical examination revealed in a 49-year-old hairdresser a 3-cm hard lump adherent to the underlying layers in the right breast. Trucut biopsy was performed. Histology showed a solid proliferation of medium-sized neoplastic polygonal cells. Immunohistochemical analysis showed tumor cells diffusely positive for cytokeratin 8/18 and calretinin and focally positive for cytokeratin 5/6 and Wilms’ tumor 1, e-cadherin, and human bone marrow endothelial-1. Estrogen receptors and progesterone receptors were negative. The final diagnosis was metastatic epithelioid malignant pleural mesothelioma. Conclusions: Immunohistochemistry is an important tool for a conclusive diagnosis of malignant pleural mesothelioma. Owing to the degree of histological and immunohistochemical overlap, a high level of clinical suspicion is essential in order to avoid unnecessary mutilating surgery

European standarts of youth work security

In this article we consider the peculiar properties of regulation of minor’s workers security within the Law of the European Union. To reveal such peculiar properties of legal regulation of a work security of youth within the Instruction of EU 89/391/EEC, as well as Instructions of 94/33/ЕС. Proper analysis of regulation of rules and rules of guarantees of the workers` rights under the age of 18 years which work on the basis of the labour contract or rules which are determined by the current legislation of the state-member and/or conformed to the current legislation of the state-member was fulfi lled. Thus, we may confirm, that except for some details, within EU territory the complex of the minimal labour standards for stable working environment which now are applied in all states-participants is created

Exit, Voice, And Loyalty In The Industrial District: The Case Of Prato

In this paper the "exit, voice and loyalty" approach by Albert O. Hirschman is applied to the case of the rise and evolution of the Prato industrial district, from post-war days until now. This is done, not so much to gain a better understanding of the specific events in Prato, but rather to shed light on the recuperation mechanisms that characterise the fundamental economic relations within the industrial district: i.e. labour relations, subcontracting relations, and relations between firms. The analysis shows how the higher competitiveness and adaptability of the district derives from the relative abundance of exit mechanisms, but also from the wealth of forms of voice, both individual and collective. These are continually being renewed within the district, thus bringing about an alternation and recombination of the mix of exit and voice, and also of the interaction models between them. The wealth of expressions of voice is a distinctive element of district relations which is linked to the multiplicity of loyalty relations (team attachment, professional category membership, local community sense of membership...) existing within the district.exit and voice, industrial district

On the Advantages of Using a Strict Hierarchy to Model Astrodynamical Problems

In this paper an algorithm is developed that combines the capabilities and advantages of several different astrodynamical models of increasing complexity. Splitting these models in a strict hierarchical order yields a clearer grasp on what is available. With the effort of developing a comprehensive model overhead, the equations for the spacecraft motion in simpler models can be readily obtained as particular cases. The proposed algorithm embeds the circular and elliptic restricted three-body problems, the four-body bicircular and concentric models, an averaged n-body model, and, at the top hierarchic ladder, the full ephemeris spice-based restricted n-body problem. The equations of motion are reduced to the assignment of 13 time-varying coefficients, which multiply the states and the gravitational potential to reproduce the proper vector field. This approach is powerful because it allows, for instance, an efficient and quick way to check solutions for different dynamics and parameters. It is shown how a gradual increase of the dynamics complexity greatly improves accuracy, the chances of success and the convergence rate of a continuation algorithm, applied to low-energy transfers
