description: The fundamental assumption of statistical mechanics is that the system is equally likely in any of the accessible microstates. Based on this assumption, the Boltzmann distribution is derived and the full theory of statistical thermodynamics can be built. In this paper, we show that the Boltzmann distribution in general can not describe the steady state of open system. Based on the effective Hamiltonian approach, we calculate the specific heat, the free energy and the entropy for an open system in steady states. Examples are illustrated and discussed.

description: Abstract

Most studies on the cystic component of ovarian tumors have been aimed at determining tumor biomarkers, with CA-125 and CEA being the most commonly studied tumor markers. The CEA content in the cystic component of the tumor is increased in mucinous type ovarian tumors although it can be increased in both cystadenoma and cystadenocarcinoma. The CEA value was found to be highest in tumor cystic fluid, followed by ascites fluid, then lowest in blood. 46 Different things were found in the tumor marker CA-125, where higher concentrations of this biomarker were found in serous type ovarian tumors compared to mucinous types, although several other studies have shown that the opposite is true. Another study also reported that there was no difference in the concentration of the tumor marker CA-125 in benign or malignant ovarian tumors. 46 Attenuation value (Hounsfield Unit) of soft tissue on Abdominal Computed Tomography. The attenuation value of x-ray beams on CT (computed tomography) is very dependent on the thickness and anatomical composition of the soft tissue that affects it.

description: We show that a deep learning model with built-in relational inductive bias can bring benefits to sample-efficient learning, without relying on extensive data augmentation. The proposed one-shot classification model performs relational matching of a pair of inputs in the form of local and pairwise attention. Our approach solves perfectly the one-shot image classification Omniglot challenge. Our model exceeds human level accuracy, as well as the previous state of the art, with no data augmentation.

description: The purpose of this study is to provide means to physicians for automated and fast recognition of airways diseases. In this work, we mainly focus on measures that can be easily recorded using a spirometer. The signals used in this framework are simulated using the linear bi-compartment model of the lungs. This allows us to simulate ventilation under the hypothesis of ventilation at rest (tidal breathing). By changing the resistive and elastic parameters, data samples are realized simulating healthy, fibrosis and asthma breathing. On this synthetic data, different machine learning models are tested and their performance is assessed. All but the Naive bias classifier show accuracy of at least 99%. This represents a proof of concept that Machine Learning can accurately differentiate diseases based on manufactured spirometry data. This paves the way for further developments on the topic, notably testing the model on real data.

description: Interactive theorem provers are tools designed for the certification of formal proofs developed by means of man-machine collaboration. Formal proofs obtained in this way cover a large variety of logical theories, ranging from the branches of mainstream mathematics, to the field of software verification. The border between these two worlds is marked by results in theoretical computer science and proofs related to the metatheory of programming languages. This last field, which is an obvious application of interactive theorem proving, poses nonetheless a serious challenge to the users of such tools, due both to the particularly structured way in which these proofs are
constructed, and to difficulties related to the management of notions typical of programming languages like variable binding.

This thesis is composed of two parts, discussing our experience in the development of the Matita interactive theorem prover and its use in the mechanization of the metatheory of programming languages. More specifically, part I covers:

- the results of our effort in providing a better framework for the development of tactics for Matita, in order to make their implementation and debugging easier, also resulting in a much clearer code;

- a discussion of the implementation of two tactics, providing infrastructure for the unification of constructor forms and the inversion of inductive predicates; we point out interactions between induction and inversion and provide an advancement over the state of the art.

In the second part of the thesis, we focus on aspects related to the formalization of programming languages. We describe two works of ours:

- a discussion of basic issues we encountered in our formalizations of part 1A of the Poplmark challenge, where we apply the extended inversion principles we implemented for Matita;

- a formalization of an algebraic logical framework, posing more complex challenges, including multiple binding and a form of hereditary substitution; this work adopts, for the encoding of binding, an extension of Masahiko Sato's canonical locally named representation we designed during our visit to the Laboratory for Foundations of Computer Science at the University of Edinburgh, under the supervision of Randy Pollack.

description: This research aims to realize a critical reading of the work of the Italian poet Andrea Zanzotto through the perspective of the Lacanian Real. What is Lacan?s Real? The real is a domain that is outside language, ?that which resists symbolization absolutely? (Lacan). The work is composed of three parts. In the first one, we shall go through the poetical itinerary in order to describe the relationship of the poet with the fundamental object of his poetical universe: the landscape. In the second part, entitled Textual analysis, we shall verify the hypothesis of the first part on four single texts, describing particularly the typical unstructured textuality of Zanzotto?s poetry. In the last part, we shall both pay attention on Zanzotto?s idea of reading and on the idea of the paratext. At this level, the analysis shows us the changes of the structural shapes facing the void and the lack of meaning from another point of view.

description: With the completion of human genome mapping, the focus of scientists seeking to explain the biological complexity of living systems is shifting from analyzing the individual components (such as a particular gene or biochemical reaction) to understanding the set of interactions amongst the large number of components that results in the different functions of the organism. To this end, the area of systems biology attempts to achieve a "systems-level" description of biology by focusing on the network of interactions instead of the characteristics of its isolated parts. In this article, we briefly describe some of the emerging themes of research in "network" biology, looking at dynamical processes occurring at the two different length scales of within the cell and between cells, viz., the intra-cellular signaling network and the nervous system. We show that focusing on the systems-level aspects of these problems allows one to observe surprising and illuminating common themes amongst them.

description: Unlike silicene, for which the demonstration of its existence has been done through numerous independent studies, the possibility of growing epitaxial germanene remains highly controversial. It has been recently shown by scanning tunneling microscopy that the (3 x 3) surface reconstruction formed upon Ge deposition on Al(111) presents a honeycomb structure, and it was assigned to a pure germanene monolayer. Using quantitative measurements by surface X-ray diffraction compared to density functional theory calculations, we demonstrate that this Ge/Al(111) (3 x 3) reconstruction corresponds, in fact, to a mixed Ge--Al honeycomb layer on top of an alloyed interfacial layer. The model of a germanene monolayer on top of the Al(111) surface can be completely excluded.

Subjects: Tourist Perception, Experiential Satisfaction, Motivation, Sustainable Tourism.

description: Abstract

Sustainable tourism is tourism that considers the future and that can contribute to the survival of the industry. Regrettably, sustainable tourism has not been fully integrated into society at the anticipated magnitude. This study was aimed to identify any factors that enable sustainable tourism development. The study employed a quantitative approach and used nonprobability sampling with a sample examination of as many as 200 respondents. The data was collected through online surveys using a Likert scale. This study applies to external and internal models completed using structural equation modeling 3.0. Based on the research results and analysis, it can be concluded that variables such as tourism perception, positive impact, experiential satisfaction, destination image, and motivation have a positive and significant influence on the sustainable tourism development attitude, and it is possible to conclude that all hypotheses are accepted. This research is expected to contribute to developing knowledge about how tourists can preserve natural resources and contribute to future tourism development, especially from the perception of tourists from different countries. Thus, this research provides valuable contributions in filling the gaps in knowledge about the real attitudes of tourists toward preserving and contributing to environmental sustainability to develop future tourism.

THE MICROBIOTA ASSOCIATED WITH THE INVASIVE POPILLIA JAPONICA (COLEOPTERA: SCARABAEIDAE) AND EVALUATION OF ENTOMOPATHOGENIC ACTIVITY OF THE ISOLATED NEMATODES

description: Popillia japonica Newman (Coleoptera: Scarabaeidae) is a highly polyphagous invasive beetle originating from Japan. It attacks more than 300 plant species, causing severe damage, and can adapt rapidly to new environments. Recently, several studies have been carried out in order to study insect-associated microorganisms and their impact on insect physiology. These microbiota-based studies have also investigated the impact of symbionts on their host?s potential to adapt to changing conditions, thus contributing to an insect?s invasive potential. However, to date, no study has been reported regarding the microbial community associated with P. japonica and the factors that may influence the composition of these communities. Therefore, our group decided to investigate the bacterial community associated with P. japonica at different developmental stages (i.e., larvae, pupae and adults (male, female) using NGS approaches. The aim of this thesis is to investigate the microbiota associated with the three gut regions of different developmental stages of P. japonica (i.e., larvae, pupae and adults) in order to address the following biological questions: 1) Do the developmental stages (i.e., larvae vs. adults) influence the bacterial community associated with P. japonica? 2) Are the bacterial communities which are associated with the three gut regions different? 3) Does the soil have an impact on shaping the bacterial community associated with the different developmental stages of P. japonica (i.e., larvae, pupae and adults)? Further, we seek to: 4) investigate the isolation and molecular characterization of the nematode associated with the third larvae of P. japonica and the microbiota associated with the isolated nematode and 5) test the entomopathogenic activity of the nematode associated with the third larvae of P. japonica. Regarding the P. japonica bacterial community, our results show that soil microbes represent an important source of gut bacteria for P. japonica larvae; but, as the insect develops, its gut microbiota richness and diversity decrease substantially. These changes are in parallel with changes in community composition. Regarding the nematode associated with the third larvae of P. japonica, the results of both the BLAST search and the reconstruction of a phylogenetic tree using the maximum-likelihood method from 18S rRNA sequences confirm the attribution of the isolated nematode to the genus Oscheius. The isolated nematode leads to the mortality of more than 50% of the host after five days. The microbiota study of the nematode shows that its bacterial community is dominated by bacteria belonging to the genus Ochrobactrum, which includes entomopathogenic species.

description: So far the amyloid hypothesis has mainly driven the Alzheimer's Disease (AD) drugs development; however most of the anti A?-clinical trials have been suspended due to the lack of significant cognitive improvements as well as to the side effects caused in AD patients in some studies. Although the negative outcomes of ?- and ?-secretases targeting therapies are reasonable explained by the significant biological functions covered by such proteases, the reason A?-centric therapies fail is still unclear. Thus, to design a successful therapy for AD it is therefore crucial to uncover the role of soluble endogenous A? in the healthy brain. Even though the amyloid peptide has been extensively studied because of its association to AD, its physiological function(s) is now being studied in much more detail. My thesis work is part of the recently emerging idea that A? ? at low concentrations - is not just a toxic waste product of the brain but it might be a relevant element involved in the maintenance of neuronal network homeostasis. Our final goal is therefore to explore the effects of the monomeric A?1-42 peptide on excitable cells.

description: Loop extrusion convincingly describes how certain Structural Maintenance of Chromosome (SMC) proteins mediate the formation of large DNA loops. Yet, most of the existing computational models cannot reconcile recent in vitro observations showing that condensins can traverse each other, bypass large roadblocks and perform steps longer than its own size. To fill this gap, we propose a three-dimensional (3D) "trans-grabbing" model for loop extrusion which not only reproduces the experimental features of loop extrusion by one SMC complex, but also predicts the formation of so-called "Z-loops" via the interaction of two or more SMCs extruding along the same DNA substrate. By performing Molecular Dynamics simulations of this model we discover that the experimentally observed asymmetry in the different types of Z-loops is a natural consequence of the DNA tethering in vitro. Intriguingly, our model predicts this bias to disappear in absence of tethering and a third type of Z-loop, which has not yet been identified in experiments, to appear. Our model naturally explains road-block bypassing and the appearance of steps larger than the SMC size as a consequence of non-contiguous DNA grabbing. Finally, it is the first to our knowledge to address how Z-loops and bypassing might occur in a way that is broadly consistent with existing cis-only 1D loop extrusion models.

Subjects: ICAR/08 Scienza delle costruzioni

description: The inherent stochastic character of most of the physical quantities involved
in engineering models has led to an always increasing interest for probabilistic
analysis.
Many approaches to stochastic analysis have been proposed. However, it
is widely acknowledged that the only universal method available to solve accurately
any kind of stochastic mechanics problem is Monte Carlo Simulation.
One of the key parts in the implementation of this technique is the accurate and
efficient generation of samples of the random processes and fields involved in the
problem at hand. In the present thesis an original method for the simulation
of homogeneous, multi-dimensional, multi-variate, non-Gaussian random fields
is proposed. The algorithm has proved to be very accurate in matching both
the target spectrum and the marginal probability. The computational efficiency
and robustness are very good too, even when dealing with strongly non-Gaussian
distributions. What is more, the resulting samples posses all the relevant, welldefined
and desired properties of “translation fields”, including crossing rates
and distributions of extremes.
The topic of the second part of the thesis lies in the field of non-destructive
parametric structural identification. Its objective is to evaluate the mechanical
characteristics of constituent bars in existing truss structures, using static loads
and strain measurements. In the cases of missing data and of damages that
interest only a small portion of the bar, Genetic Algorithm have proved to be
an effective tool to solve the problem.

description: The outbreak of coronavirus disease 2019 (COVID-19) has had a significant repercussion on the health, economy, politics and environment, making coronavirus-related issues more complicated and difficult to solve adequately by relying on a single field. Interdisciplinary research can provide an effective solution to complex issues in the related field of coronavirus. However, whether coronavirus related research becomes more interdisciplinary still needs corroboration. In this study, we investigate interdisciplinary status of the coronavirus-related fields via the COVID-19 Open Research Dataset (CORD-19). To this end, we calculate bibliometric indicators of interdisciplinarity and a co-occurrence analysis method. The results show that co-occurrence relationships between cited disciplines have evolved dynamically over time. The two types of co-occurrence relationships, Immunology and Microbiology & Medicine and Chemical Engineering & Chemistry, last for a long time in this field during 1990-2020. Moreover, the number of disciplines cited by coronavirus-related research increases, whereas the distribution of disciplines is uneven, and this field tends to focus on several dominant disciplines such as Medicine, Immunology and Microbiology, Biochemistry, Genetics and Molecular Biology. We also gauge the disciplinary diversity of COVID-19 related papers published from January to December 2020; the disciplinary variety shows an upward trend, while the degree of disciplinary balance shows a downward trend. Meanwhile, the comprehensive index 2Ds demonstrates that the degree of interdisciplinarity in coronavirus field decreases between 1990 and 2019, but it increases in 2020. The results help to map the interdisciplinarity of coronavirus-related research, gaining insight into the degree and history of interdisciplinary cooperation.

description: Il testo ripercorre le origini del romanzo poliziesco, la sua
struttura, le tecniche narrative utilizzate e l’evoluzione del genere
che ha condotto alla nascita del Noir francese e del Noir
Mediterraneo.
Arrivando ad osservare che per le sue caratteristiche, la
letteratura noir in generale presenta specificità di tipo culturale,
ambientale e linguistico, che risultano molto evidenti nell’opera
di Izzo, si giunge a considerare come sia necessario per il
traduttore porsi rispetto all’opera come un antropologo o un
etnologo, di farsi cioè interprete di una “cultura”.
Nella terza parte del lavoro vengono presentati la Trilogia di
Izzo, la struttura narrativa e gli elementi socio-culturali presenti
nell’opera.
La quarta parte propone le teorie relative sia al problema
della traduzione interlinguistica, sia a quello della traduzione
intralinguistica e successivamente dopo una analisi della
traduzione italiana dei testi, presenta, in appendice, una
possibile traduzione del prologo di Total Khéops, inteso come
sintesi delle caratteristiche narrative e culturali dell’autore.
La parte conclusiva di questo lavoro riguarda la traduzione
intercodica e, seguendo la linea di pensiero che ha governato
l’analisi della Trilogia vengono presi in esame e messi a confronto
col testo narrativo alcuni dialoghi significativi dell’adattamento

description: We investigate theoretically and experimentally the static magnetic properties of single crystals of the molecular-based Single-Chain Magnet (SCM) of formula [Dy(hfac)$_{3}$NIT(C$_{6}$H$_{4}$OPh)]$_{\infty}$ comprising alternating Dy$^{3+}$ and organic radicals. A peculiar inversion between maxima and minima in the angular dependence of the magnetic molar susceptibility $χ_{M}$ occurs on increasing temperature. Using information regarding the monomeric building block as well as an {\it ab initio} estimation of the magnetic anisotropy of the Dy$^{3+}$ ion, this anisotropy-inversion phenomenon can be assigned to weak one-dimensional ferromagnetism along the chain axis. This indicates that antiferromagnetic next-nearest-neighbor interactions between Dy$^{3+}$ ions dominate, despite the large Dy-Dy separation, over the nearest-neighbor interactions between the radicals and the Dy$^{3+}$ ions. Measurements of the field dependence of the magnetization, both along and perpendicularly to the chain, and of the angular dependence of $χ_{M}$ in a strong magnetic field confirm such an interpretation. Transfer matrix simulations of the experimental measurements are performed using a classical one-dimensional spin model with antiferromagnetic Heisenberg exchange interaction and non-collinear uniaxial single-ion anisotropies favoring a canted antiferromagnetic spin arrangement, with a net magnetic moment along the chain axis. The fine agreement obtained with experimental data provides estimates of the Hamiltonian parameters, essential for further study of the dynamics of rare-earths based molecular chains.

description: Abstract

This study aims to test the influence of self-efficacy, knowledge sharing, and motivation on the creativity of educators in the National Police educational institutions. The research method used was a cross-sectional survey with 248 certified educators. Data analysis uses structural equation modeling techniques with a partial least squares approach. The findings show that self-efficacy significantly increases teaching creativity with a relatively low effect. In addition, self-efficacy also positively affects knowledge sharing, which contributes to increased teaching creativity, although these two relationships vary. Educator motivation is also significant in increasing teaching creativity and knowledge sharing, with a moderate effect measure.

description: Let $ξ$ be a real irrational number. We are interested in sequences of linear forms in 1 and $ξ$, with integer coefficients, which tend to 0. Does such a sequence exist such that the linear forms are small (with given rate of decrease) and the coefficients have some given rate of growth? If these rates are essentially geometric, a necessary condition for such a sequence to exist is that the linear forms are not too small, a condition which can be expressed precisely using the irrationality exponent of $ξ$. We prove that this condition is actually sufficient, even for arbitrary rates of growth and decrease. We also make some remarks and ask some questions about multivariate generalizations connected to Fischler-Zudilin's new proof of Nesterenko's linear independence criterion.

description: Abstract

The study of banana fibers aimed to study the fibers obtained from the fiber extraction process for use in food packaging. The research selected 8-9-month-old Nam Wa bananas with trunks 2-3 meters high, cut the banana trees about 20 centimeters, passed through the process of releasing steam followed by chemical treatment to extract banana fibers, carried out at boiling temperature for 60 minutes, then washed with clean water, and then pressed the banana fibers to remove excess water. The test weighed the banana fibers. After that, the banana samples packed in containers with open lids were put into an oven at 70 ° C for 24 hours. From the statistics, it shows that all data sets follow a normal distribution. This type of graph is also a good way to consider whether the residuals from the regression analysis are normally distributed or not. The p-value for the test is 0.719, indicating that the data follow a normal distribution. From the Analysis of Variance, the P-Value is equal to 0.000, indicating that the pseudo stem banana from 12 layers of Namwa banana tree had no difference at the significance level of 0.000. The research selected 5 consecutive banana layers for research, and layers 3-7 were selected for further analysis. The results of the research found that banana fiber produced by the extraction of the exposed layers was a new and efficient production process, which produced the extracted layer through all layers. The 7 layer fiber had an average diameter of 125.7 µm, the highest, while the smallest fiber was layer 4, with an average diameter of 86.2 µm. It showed that the banana layer level affected the fiber size as the size increased with the layer, but there was no significant difference at the significance level of 0.000. It showed that the experimental results could be practically applied. From all 5 tested layers, all layers can be used as food packaging regardless of the banana layer level. Analysis of banana fiber layers produced by fiber extraction, the layer with large fibers also had a high swelling rate. The mixture of layer ratio 7 had a swelling rate of 3.88%, which would increase with the size of each layer of fiber.

description: We revisit the classic problem of the effective diffusion constant of a Brownian particle in a square lattice of reflecting impenetrable hard disks. This diffusion constant is also related to the effective conductivity of non-conducting and infinitely conductive disks in the same geometry. We show how a recently derived Green's function for the periodic lattice can be exploited to derive a series expansion of the diffusion constant in terms of the disk's volume fraction $φ$. Secondly we propose a variant of the Fick-Jacobs approximation to study the large volume fraction limit. This combination of analytical results is shown to describe the behavior of the diffusion constant for all volume fractions.

description: Strong spin-orbit coupling in noncentrosymmetric materials and interfaces results in remarkable physical phenomena, such as nontrivial spin textures, which may exhibit Rashba, Dresselhaus, and other intricated configurations. This provides a promising basis for nonvolatile spintronic devices and further implications. Here, we simulate from first principles a two-dimensional electron gas in ultrathin platinum and palladium layers grown on ferroelectric PbTiO$_3$(001). The latter allows, in principle, to switch and control the spin-to-charge conversion by the polarization reversal. We show how the band structure and its Rashba splitting differ in the Pt and Pd overlayers and how these electronic features change with increasing the overlayer thickness and upon reversal of polarization. Besides, for both overlayers, we simulated their current-voltage ($I-V$) characteristics, the resistance of which upon the polarization reversal changes between 20% and several hundred percent. The reported findings can be used to model directly the Rashba-Edelstein effect.

Freedom of work-related choices and work-attachment : an exploratory study of secondary teachers

Publisher: name: University of British Columbia

description: The balance between freedom and constraint in the work situation lies at the core of interests in this study. The primary aim of the study is to examine among secondary school teachers in British Columbia the relationship between their attachment to work (i.e., the tendency to engage in their job consistently and continuously) and their personal assessments of freedom of choice concerning their (a) occupation, (b) working conditions, and (c) discretion in the work process. The study also deals with the impact that work-attachment has on the extent to which teachers (a) establish collegial friendship ties and (b) place special emphasis on student relations in instructional matters. Data for the study are based on self-administered questionnaires from 224 secondary school teachers in British Columbia collected during the academic year 1972-73. Supplementary data are provided by written comments of respondents toward the questionnaire, follow-up conversations with selected respondents, and observations of the teachers themselves in the classroom, staff rooms, and staff meetings. The data suggest that the relationship between any of the independent freedom-of-choice variables and work-attachment is generally contingent upon the teacher's age, sex, and size of school district in which he or she is located. Specifically, the findings indicate that (a) a high degree of freedom concerning choice of occupation is substantially related to work-attachment among young teachers (22-35 years) and among women teachers; (b) the original weak relationship between choice of working conditions and work-attachment was not greatly altered under the same controls for age, sex, or school district size; and (c) the relationship between work-discretion and work-attachment was substantially strengthened among teachers located in larger school districts. The data also show that women teachers and teachers. In. large-school districts who indicate a high degree of work-attachment tend to establish stronger collegial friendship ties. The impact of work-attachment on the teacher's tendency to emphasize student relations in. instructional matters is evident only in the case of the relatively older (36-65 years) teachers. Both theoretical and practical implications of the findings are assessed, and suggestions for extended research are specified.

description: We study the classical and quantum phase transitions of Sp(4) spin systems on three dimensional stacked square and triangular lattices. We present general Ginzburg-Landau field theories for various types of Sp(4) spin orders with different ground state manifolds such as CP(3), S^7/Z_2, Grassmann manifold G_{2,5}, G_{2,6} and so on, based on which the nature of the classical phase transitions are studied, and a global phase diagram is presented. The classical phase transitions close to quantum phase transitions toward spin liquid states are also discussed based on renormalization group (RG) flow. Our results can be directly applied to the simplest Sp(4) and SU(4) Heisenberg models which can be realized using spin-3/2 atoms and Alkaline earth atoms trapped in optical lattice.
