Publisher: name: Revista Turismo & Desenvolvimento
Year: 2016

description: O contributo do turismo rural para a economia em geral e em particular para as economias locais parece ser já inquestionável. Esta evidência é apresentada em vários estudos presentes na literatura e reforçada por um conjunto de organismos oficiais. Este estudo tem como objetivo geral avaliar a perceção da população residente sobre a importância do turismo rural para o desenvolvimento sustentável da Península de Setúbal. Especificamente, o estudo pretende compreender a perceção da população no que concerne aos impactos desta atividade, assim como avaliar se os fatores, idade, género, nível de educação e residência na região têm influência sobre uma perceção mais positiva ou negativa relativamente aos impactos do turismo rural no desenvolvimento desta península. Propõe-se uma pesquisa exploratória suportada numa análise quantitativa e qualitativa. Os resultados do estudo indiciam um elevado otimismo da população relativamente ao impacto do turismo rural para o desenvolvimento da região, tendo sido verificada uma influência muito reduzida dos fatores sociodemográficos para a explicação das perceções dos residentes.

The social construction of cooperation: exchange, identification and collective intentions within the organization
Creators: name: Sguera, Francesco <1977>

Subjects: SECS-P/07 Economia aziendale

description: My aim is to develop a theory of cooperation within the organization and empirically test it. Drawing upon social exchange theory, social identity theory, the idea of collective intentions, and social constructivism, the main assumption of my work implies that both cooperation and the organization itself are continually shaped and restructured by actions, judgments, and symbolic interpretations of the parties involved. 
Therefore, I propose that the decision to cooperate, expressed say as an intention to cooperate, reflects and depends on a three step social process shaped by the interpretations of the actors involved. The first step entails an instrumental evaluation of cooperation in terms of social exchange. In the second step, this “social calculus” is translated into cognitive, emotional and evaluative reactions directed toward the organization. Finally, once the identification process is completed and membership awareness is established, I propose that individuals will start to think largely in terms of “We” instead of “I”. Self-goals are redefined at the collective level, and the outcomes for self, others, and the organization become practically interchangeable.
I decided to apply my theory to an important cooperative problem in management research: knowledge exchange within organizations. Hence, I conducted a quantitative survey among the members of the virtual community, “www.borse.it” (n=108). Within this community, members freely decide to exchange their knowledge about the stock market among themselves. Because of the confirmatory requirements and the structural complexity of the theory proposed (i.e., the proposal that instrumental evaluations will induce social identity and this in turn will causes collective intentions), I use Structural Equation Modeling to test all hypotheses in this dissertation. The empirical survey-based study found support for the theory of cooperation proposed in this dissertation. 
The findings suggest that an appropriate conceptualization of the decision to exchange knowledge is one where collective intentions depend proximally on social identity (i.e., cognitive identification, affective commitment, and evaluative engagement) with the organization, and this identity depends on instrumental evaluations of cooperators (i.e., perceived value of the knowledge received, assessment of past reciprocity, expected reciprocity, and expected social outcomes of the exchange). Furthermore, I find that social identity fully mediates the effects of instrumental motives on collective intentions.

Abstract: Resistive in-memory computing (IMC) architectures currently lag behind SRAM IMCs and digital accelerators in both energy efficiency and compute density due to their low compute accuracy. To understand the reasons underlying this trend, we develop a behavioral model of resistive IMCs to analyze the signal-to-noise-plus-distortion ratio (SNDR) of MRAM, ReRAM, and FeFET-based IMCs, employing parameter variation and noise models which are validated w.r.t. measured results from a recent MRAM-based IMC prototype in a 22nm process. We obtain fundamental limits on the maximum achievable SNDR under various operating conditions and identify device and circuit parameters that have the most significant impact on the SNDR. Finally, we study the impact of bank level SNDR on network-level accuracy by mapping ResNet-20 (CIFAR-10) to find that MRAM and FeFET-based architectures find it challenging to meet the minimum SNDR required for the classification accuracy to approach that of a fixed-point digital architecture – a result that clearly implies the need for algorithmic and learning-based methods, to improve the inference accuracy of resistive IMC architectures. Next, we hypothesize that the low native SNDR of resistive IMCs might provide resilience against security attacks, such as model extraction attacks (MEAs). This hypothesis is invalidated by employing the behavioral model to develop resistive IMC-specific MEAs,  which are then applied to the 22nm MRAM-based IMC prototype and shown to be quite effective in extracting model weights. The security vulnerability of resistive IMCs is shown to be a function of the SNDR, and the trade-off between energy-accuracy-security of resistive IMCs is quantified. This work opens up opportunities for AI chip designers and security experts to design resistive IMCs that are secure, energy-efficient, and accurate.
Chiplets for AI and Data Centers: Trends and Innovations in I/O Circuit Designs Slides

Publisher: name: IEEE
Year: 2025

Webinar Slides
Abstract: Today’s complex systems for high-performance computing feature chiplets using advanced packaging technologies, commercially known as EMIB, CoWoS, InFO, FOCoS, and several others from multiple sources. These 2D/2.5D structures require ultra-dense I/O PHYs to deliver a large amount of data between dice over a distance of a few millimeters without adding much power and area penalty to each die.

This talk will highlight several important use cases of chiplets for AI and data centers, and then delve deeper into the latest trends in I/O circuit designs for chiplets. It will also discuss ongoing standardization efforts and I/O circuits for 3D integrations.
Consistency relation for the Lorentz invariant single-field inflation

description: In this paper we compute the sizes of equilateral and orthogonal shape bispectrum for the general Lorentz invariant single-field inflation. The stability of field theory implies a non-negative square of sound speed which leads to a consistency relation between the sizes of orthogonal and equilateral shape bispectrum, namely $f_{NL}^{orth.}\lesssim -0.054 f_{NL}^{equil.}$. In particular, for the single-field Dirac-Born-Infeld (DBI) inflation, the consistency relation becomes $f_{NL}^{orth.}\simeq 0.070 f_{NL}^{equil.}\lesssim 0$. These consistency relations are also valid in the mixed scenario where the quantum fluctuations of some other light scalar fields contribute to a part of total curvature perturbation on the super-horizon scale and may generate a local form bispectrum. A distinguishing prediction of the mixed scenario is $τ_{NL}^{loc.}>({6\over 5}f_{NL}^{loc.})^2$. Comparing these consistency relations to WMAP 7yr data, there is still a big room for the Lorentz invariant inflation, but DBI inflation has been disfavored at more than 68% CL.

Inclusive and differential cross section measurements of single top quark production in association with a Z boson in proton-proton collisions at $\sqrt{s}$ = 13 TeV

description: Inclusive and differential cross sections of single top quark production in association with a Z boson are measured in proton-proton collisions at a center-of-mass energy of 13 TeV with a data sample corresponding to an integrated luminosity of 138 fb$^{-1}$ recorded by the CMS experiment. Events are selected based on the presence of three leptons, electrons or muons, associated with leptonic Z boson and top quark decays. The measurement yields an inclusive cross section of 87.9 $_{-7.3}^{+7.5}$ (stat) $_{-6.0}^{+7.3}$ (syst) fb for a dilepton invariant mass greater than 30 GeV, in agreement with standard model (SM) calculations and the most precise determination to date. The ratio between the cross sections for the top quark and the top antiquark production in association with a Z boson is measured as 2.37 $_{-0.42}^{+0.56}$ (stat) ${}_{-0.13}^{+0.27}$ (syst). Differential measurements at parton and particle levels are performed for the first time. Several kinematic observables are considered to study the modeling of the process. Results are compared to theoretical predictions with different assumptions on the source of the initial-state b quark and found to be in agreement, within the uncertainties. Additionally, the spin asymmetry, which is sensitive to the top quark polarization, is determined from the differential distribution of the polarization angle at parton level to be 0.54 $\pm$ 0.16 (stat) $\pm$ 0.06 (syst), in agreement with SM predictions.

description: We discuss the relations between the Atiyah-Hirzebruch spectral sequence and the Gysin map for a multiplicative cohomology theory, on spaces having the homotopy type of a finite CW-complex. In particular, let us fix such a multiplicative cohomology theory h* and let us consider a smooth manifold X of dimension n and a compact submanifold Y of dimension p, satisfying suitable hypotheses about orientability. We prove that, starting the Atiyah-Hirzebruch spectral sequence with the Poincarè dual of Y in X, which, in our setting, is a simplicial cohomology class with coefficients in h^{n-p}(one-point), if such a class survives until the last step, it is represented by the image via the Gysin map of the unit cohomology class of Y. We then prove the analogous statement for a generic cohomology class on Y.

description: An analysis of arrival directions of extensive air showers (EAS) registered with the EAS MSU and EAS-1000 prototype arrays has revealed a region of excessive flux of PeV cosmic rays in the direction toward pulsars PSR J1840+5640 and LAT PSR J1836+5925 at significance level up to 4.5sigma. The first of the pulsars was discovered almost 30 years ago and is a well-studied old radio pulsar located at the distance of 1.7pc from the Solar system. The second pulsar belongs to a new type of pulsars, discovered by the space gamma-ray observatory Fermi, pulsations of which are not observed in optical and radio wavelengths but only in the gamma-ray range of energies (gamma-ray-only pulsars). In our opinion, the existence of the region of excessive flux of cosmic rays registered with two different arrays provides a strong evidence that isolated pulsars can give a noticeable contribution to the flux of Galactic cosmic rays in the PeV energy range.

Realization of the Exactly Solvable Kitaev Honeycomb Lattice Model in a Spin Rotation Invariant System

Publisher: name: arXiv

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: The exactly solvable Kitaev honeycomb lattice model is realized as the low energy effect Hamiltonian of a spin-1/2 model with spin rotation and time-reversal symmetry. The mapping to low energy effective Hamiltonian is exact, without truncation errors in traditional perturbation series expansions. This model consists of a honeycomb lattice of clusters of four spin-1/2 moments, and contains short-range interactions up to six-spin(or eight-spin) terms. The spin in the Kitaev model is represented not as these spin-1/2 moments, but as pseudo-spin of the two-dimensional spin singlet sector of the four antiferromagnetically coupled spin-1/2 moments within each cluster. Spin correlations in the Kitaev model are mapped to dimer correlations or spin-chirality correlations in this model. This exact construction is quite general and can be used to make other interesting spin-1/2 models from spin rotation invariant Hamiltonians. We discuss two possible routes to generate the high order spin interactions from more natural couplings, which involves perturbative expansions thus breaks the exact mapping, although in a controlled manner.

description: One studies Cremona monomial maps by combinatorial means. Among the results is a simple integer matrix theoretic proof that the inverse of a Cremona monomial map is also defined by monomials of fixed degree, and moreover, the set of monomials defining the inverse can be obtained explicitly in terms of the initial data. A neat consequence is drawn for the plane Cremona monomial group, in particular the known result saying that a plane Cremona (monomial) map and its inverse have the same degree. Included is a discussion about the computational side and/or implementation of the combinatorial invariants stemming from these questions.

Metaheuristics for Search Problems in Genomics - New Algorithms and Applications

Year: 2012
Subjects: ING-INF/05 Sistemi di elaborazione delle informazioni

description: In this thesis we made the first steps towards the systematic application of a methodology for automatically building formal models of complex biological systems. Such a methodology could be useful also to design artificial systems possessing desirable properties such as robustness and evolvability.
The approach we follow in this thesis is to manipulate formal models by means of adaptive search methods called metaheuristics.
In the first part of the thesis we develop state-of-the-art hybrid metaheuristic algorithms to tackle two important problems in genomics, namely, the Haplotype Inference by parsimony and the Founder Sequence Reconstruction Problem. We compare our algorithms with other effective techniques in the literature, we show strength and limitations of our approaches to various problem formulations and, finally, we propose further enhancements that could possibly improve the performance of our algorithms and widen their applicability.
In the second part, we concentrate on Boolean network (BN) models of gene regulatory networks (GRNs). We detail our automatic design methodology and apply it to four use cases which correspond to different design criteria and address some limitations of GRN modeling by BNs. Finally, we tackle the Density Classification Problem with the aim of showing the learning capabilities of BNs.
Experimental evaluation of this methodology shows its efficacy in producing network that meet our design criteria.
Our results, coherently to what has been found in other works, also suggest that networks manipulated by a search process exhibit a mixture of characteristics typical of different dynamical regimes.

We also show that our expressions describe better the tau to 3pi ALEPH data and are able to fit BABAR data on the isovector component of e^+e^- -> KKpi. The theoretical foundations of our framework are the large-N_C limit of QCD, the chiral structure exhibited at low energies and the proper asymptotic behaviour, ruled by QCD, that is demanded to the associated form factors.

description: Este artigo tem como objetivo mostrar como as pesquisas em hospitalidade realizadas nos últimos 25 anos, no Brasil, têm amadurecido a ponto de poderem figurar em posição relevante dentre os estudos desenvolvidos em outras partes do mundo, anteriormente realizados majoritariamente por pesquisadores americanos, britânicos e franceses sob a influência de diferentes correntes do pensamento humano e social aplicado. A condição de relativa liberdade linguística – por conta do acesso, em alguma medida, a publicações em outros idiomas, entre os quais o inglês e francês - e epistemológica - que permite escapar da chamada tirania da dominância epistêmica - da comunidade brasileira de pesquisadores em hospitalidade, tem permitido aos pesquisadores brasileiros aprofundar-se no tema e sinalizado a possibilidade de ascender o país a uma posição relevante no cenário internacional da pesquisa em hospitalidade. Chegou-se a esta conclusão a partir de pesquisa direta sobre as produções mais importantes relacionadas ao tema em língua inglesa, francesa e portuguesa, no período entre 1990 e 2014. Ainda que o distanciamento teórico-metodológico entre estes trabalhos seja recorrente, há conexões entre as publicações de referência. Os resultados mostram que há, mundialmente, uma rede de estudos e pesquisas cujos padrões de organização começam, aos poucos, a favorecer a transferência efetiva de conhecimento entre pesquisadores, embora estas relações ainda sejam incipientes. Neste sentido, nossos indicadores identificam que um grupo de pesquisadores brasileiros tem estabelecido pontos de conexão entre diferentes domínios geográficos, linguísticos e epistemológicos, o que pode favorecer a efetiva construção de uma rede internacional de pesquisa em hospitalidade. Para análise dos dados, utilizou-se o software de Análise de Redes Sociais (ARS) Yed (YWorks) e os dados foram sistematizados a partir da aplicação da metodologia de análise de citações.

description: Motivated by the need to understand which are the underlying forces that trigger network evolution, we develop a multilevel theoretical and empirically testable model to examine the relationship between changes in the external environment and network change. We refer to network change as the dissolution or replacement of an interorganizational tie, adding also the case of the formation of new ties with new or preexisting partners. Previous research has paid scant attention to the organizational consequences of quantum change enveloping entire industries in favor of an emphasis on continuous change. To highlight radical change we introduce the concept of environmental jolt. The September 11 terrorist attacks provide us with a natural experiment to test our hypotheses on the antecedents and the consequences of network change. Since network change can be explained at multiple levels, we incorporate firm-level variables as moderators. The empirical setting is the global airline industry, which can be regarded as a constantly changing network of alliances. The study reveals that firms react to environmental jolts by forming homophilous ties and transitive triads as opposed to the non jolt periods. Moreover, we find that, all else being equal, firms that adopt a brokerage posture will have positive returns. However, we find that in the face of an environmental jolt brokerage relates negatively to firm performance. Furthermore, we find that the negative relationship between brokerage and performance during an environmental jolt is more significant for larger firms. Our findings suggest that jolts are an important predictor of network change, that they significantly affect operational returns and should be thus incorporated in studies of network dynamics.

description: Heavy pig breeding in Italy is mainly oriented for the production of high quality processed products. Of particular importance is the dry cured ham production, which is strictly regulated and requires specific carcass characteristics correlated with green leg characteristics. Furthermore, as pigs are slaughtered at about 160 kg live weight, the Italian pig breeding sector faces severe problems of production efficiency that are related to all biological aspects linked to growth, feed conversion, fat deposition and so on. It is well known that production and carcass traits are in part genetically determined. Therefore, as a first step to understand genetic basis of traits that could have a direct or indirect impact on dry cured ham production, a candidate gene approach can be used to identify DNA markers associated with parameters of economic importance.
In this thesis, we investigated three candidate genes for carcass and production traits (TRIB3, PCSK1, MUC4) in pig breeds used for dry cured ham production, using different experimental approaches in order to find molecular markers associated with these parameters.
description: L’allevamento del suino pesante italiano è principalmente orientato verso la produzione di prodotti stagionati di alto pregio. Particolarmente importante è la produzione del prosciutto crudo, che è strettamente regolata e richiede specifiche caratteristiche della carcassa correlate con le caratteristiche della coscia fresca. Inoltre dato che i suini vengono macellati ad un peso di circa 160kg, il settore dell’allevamento del suino pesante italiano si trova a dover far fronte a numerosi problemi di efficienza di produzione che sono correlati a tutti gli aspetti biologici legati a crescita, conversione alimentare, deposizione di grasso e così via. E’ ben noto che caratteri produttivi e caratteristiche della carcassa sono in parte geneticamente determinate. Perciò come primo step per comprendere le basi genetiche di attributi che possono avere un impatto diretto o indiretto nella produzione del prosciutto crudo, l’approccio del gene candidato può essere usato per identificare marcatori a DNA associati a caratteri di importanza economica.
In questa tesi abbiamo investigato tre geni candidati per caratteri produttivi e relativi alla carcassa (TRIB3, PCSK1, MUC4)in razze suine usate per la produzione del prosciutto crudo, utilizzando differenti approcci sperimentali al fine di trovare marcatori molecolari associati con questi caratteri.

description: We denote by C_p(X,G) the group of all continuous functions from a space X to a topological group G endowed with the topology of pointwise convergence. We say that spaces X and Y are G-equivalent provided that the topological groups C_p(X,G) and C_p(Y,G) are topologically isomorphic. We investigate which topological properties are preserved by G-equivalence, with a special emphasis being placed on characterizing topological properties of X in terms of those of C_p(X,G). Since R-equivalence coincides with l-equivalence, this line of research "includes" major topics of the classical C_p-theory of Arhangel'skii as a particular case (when G = R). We introduce a new class of TAP groups that contains all groups having no small subgroups (NSS groups). We prove that: (i) for a given NSS group G, a G-regular space X is pseudocompact if and only if C_p(X,G) is TAP, and (ii) for a metrizable NSS group G, a G^*-regular space X is compact if and only if C_p(X,G) is a TAP group of countable tightness. In particular, a Tychonoff space X is pseudocompact (compact) if and only if C_p(X,R) is a TAP group (of countable tightness). We show that Tychonoff spaces X and Y are T-equivalent if and only if their free precompact Abelian groups are topologically isomorphic, where T stays for the quotient group R/Z. As a corollary, we obtain that T-equivalence implies G-equivalence for every Abelian precompact group G. We establish that T-equivalence preserves the following topological properties: compactness, pseudocompactness, sigma-compactness, the property of being a Lindelof Sigma-space, the property of being a compact metrizable space, the (finite) number of connected components, connectedness, total disconnectedness. An example of R-equivalent (that is, l-equivalent) spaces that are not T-equivalent is constructed.

description: Recently, the Economic Community of West African States (ECOWAS) lost three of its founding members, which had devastating implications for the effective performance of the regional institution. The efforts of Nigeria, a major player in the regiony, to strengthen and provide direction have not yielded the desired results, as the influence of the regional body continues to diminish.   Therefore, this study examined Nigeria’s role in mitigating the contemporary challenges facing the regional body. The study elicited data from existing sources to better understand the problems. The study found that the lack of a central authority to enforce rules and regulations has hindered the effectiveness of the regional body. Study findings also show that external interference in the politics of the region has weakened the effectiveness of the body. Furthermore, results revealed that Nigeria’s domestic challenges have worsened the problems of the regional international institution

Finding Exogenous Variables in Data with Many More Variables than Observations

description: Many statistical methods have been proposed to estimate causal models in classical situations with fewer variables than observations (p>n). In this paper, we propose a method to find exogenous variables in a linear non-Gaussian causal model, which requires much smaller sample sizes than conventional methods and works even when p>>n. The key idea is to identify which variables are exogenous based on non-Gaussianity instead of estimating the entire structure of the model. Exogenous variables work as triggers that activate a causal chain in the model, and their identification leads to more efficient experimental designs and better understanding of the causal mechanism. We present experiments with artificial data and real-world gene expression data to evaluate the method.

Isoperla bithynica (Kempy 1908). Distribution. The most common and abundant species of family Perlodidae, found almost everywhere in KBR. Predaceous larvae feed on larvae and pupae of the chironomid, Diamesa insignipes. Family Chloroperlidae in KBR is represented by 2 genera and 2 species that have limited natural habitat (Fig. 3). 7. Pontoperla katherinae Balynsky 1950 Distribution. The preimago stage of development is common among the benthos of glacial streams and spring rivers of foothill and mountain zones of KBR, but at 500 m below sea level larvae of this species were not found. In the foothill and mountain zone frequently associated with detrital materials in spring and summer, we found 17- 45 specimens per square meter. The average weight of mature larvae (length 7-8 mm) is 6.3-7.1 mg. The larvae are concentrated near the water and substrate interface, on stones washed by water. Most were found in streams with well developed riparian forests (Yakimov et al 2011 b). 6. Isoperla bithynica (Kempy 1908). Distribution.

description: We performed a systematic study on the properties of CeFeAs$_{1-x}$P$_{x}$O ($0\leq x\leq 1$) by electrical resistivity, magnetization and specific heat measurements. The c-axis lattice constant decreases significantly with increasing P content, suggesting a remarkable chemical pressure. The Fe-3d electrons show the enhanced metallic behavior upon P-doping and undergo a magnetic quantum phase transition around $x \approx 0.4$. Meanwhile, the Ce-4f electrons develop a ferromagnetic order near the same doping level. The ferromagnetic order is vanishingly small around $x=0.9$. The data suggest a heavy-fermion-like behavior as $x\geq 0.95$. No superconductivity is observed down to 2 K. Our results show the ferromagnetic ordered state as an intermediate phase intruding between the antiferromagnetic bad metal and the nonmagnetic heavy fermion metal and support the cerium-containing iron pnictides as a unique layered Kondo lattice system.

Characterization and modeling of low-frequency noise in MOSFETs

Year: 2009
Subjects: ING-INF/01 Elettronica

description: For many years, RF and analog integrated circuits have been mainly developed using bipolar and compound semiconductor technologies due to their better performance. In the last years, the advance made in CMOS technology allowed analog and RF circuits to be built with such a technology, but the use of CMOS technology in RF application instead of
bipolar technology has brought more issues in terms of noise. The noise cannot be completely eliminated and will therefore ultimately limit the accuracy of measurements and set a lower limit on how small signals can be detected and processed in an electronic circuit. One kind of noise which affects MOS transistors much more than bipolar ones is the low-frequency noise. In MOSFETs, low-frequency noise is mainly of two kinds: flicker or 1/f noise and random telegraph signal noise (RTS). The objective of this thesis is to characterize and to model the low-frequency noise by studying RTS and flicker noise under both constant and switched bias conditions. The effect of different biasing schemes on both RTS and flicker noise in time and frequency domain has been investigated.
