description: We explore a chameleon type of interacting dark matter-dark energy scenario in which a scalar field adiabatically traces the minimum of an effective potential sourced by the dark matter density. We discuss extensively the effect of this coupling on cosmological observables, especially the parameter degeneracies expected to arise between the model parameters and other cosmological parameters, and then test the model against observations of the cosmic microwave background (CMB) anisotropies and other cosmological probes. We find that the chameleon parameters $α$ and $β$, which determine respectively the slope of the scalar field potential and the dark matter-dark energy coupling strength, can be constrained to $α< 0.17$ and $β< 0.19$ using CMB data alone. The latter parameter in particular is constrained only by the late Integrated Sachs-Wolfe effect. Adding measurements of the local Hubble expansion rate $H_0$ tightens the bound on $α$ by a factor of two, although this apparent improvement is arguably an artefact of the tension between the local measurement and the $H_0$ value inferred from Planck data in the minimal $Λ$CDM model. The same argument also precludes chameleon models from mimicking a dark radiation component, despite a passing similarity between the two scenarios in that they both delay the epoch of matter-radiation equality. Based on the derived parameter constraints, we discuss possible signatures of the model for ongoing and future large-scale structure surveys.

description: We show that the Natanzon family of potentials is necessarily dropped into a restricted set of distinct potentials involving a fewer number of independent parameters if the potential term in the Schrödinger equation is proportional to an energy-independent parameter and if the potential shape is independent of both energy and that parameter. In the hypergeometric case only six such potentials exist, all five-parametric. Among these, only two (Eckart, Pöschl-Teller) are independent in the sense that each cannot be derived from the other by specifications of the involved parameters. Discussing the solvability of the Schrödinger equation in terms of the single-confluent Heun functions, we show that in this case there exist in total fifteen seven-parametric potentials, of which independent are nine. Six of the inde-pendent potentials present different generalizations of the hypergeometric or confluent hypergeometric ones, while three others do not possess hypergeometric sub-potentials. The result for the double- and bi-confluent Heun equations produces the three independent double- and five independent bi-confluent six-parametric Lamieux-Bose potentials, and the general five-parametric quartic oscillator potential for the tri-confluent Heun equation.

description: The linear energy dispersion of graphene electrons leads to a strongly nonlinear electromagnetic response of this material. We develop a general quantum theory of the third-order nonlinear local dynamic conductivity of graphene $σ_{αβγδ}(ω_1,ω_2,ω_3)$, which describes its nonlinear response to a uniform electromagnetic radiation. The derived analytical formulas describe a large number of different nonlinear phenomena such as the third harmonic generation, the four wave mixing, the saturable absorption, the second harmonic generation stimulated by a dc electric current, etc., which may be used in different terahertz and optoelectronic devices.

The contribution of the Indian Council for Cultural Relations (ICCR) to a foreign student's achievement of his or her goals is significant. ICCR is more than just a financial support organization for educational purposes; it is a solid pillar for every foreigner pursuing their aspirations of achievement and illumination. Throughout student stay and education in India, each member of the ICCR family is dedicated to motivating, supporting, soothing, securing, and advising you. India's greatest achievement is that it has remained true to its own land's values and religious teachings throughout the years. The author tries to spotlight the reasons that have led to India's transformation into soft power. Finally, the article discusses the principles of Indian foreign policy that hold Indian engaged with the world tightly.

description: OBJECTIVES:There is increased interest in measuring patient-reported outcomes (PROs) such as quality of life (QoL) among patients with inflammatory bowel disease (IBD). We aimed to create and validate a new measure of QoL to assess the psychosocial burden of IBD using publicly available assessment tools.METHODS:Using the Crohn's & Colitis Foundation's IBD Partners cohort, we performed several cross-sectional and longitudinal analyses to create a new PRO-based evaluation (PROBE) of QoL among patients with Crohn's disease (CD) and ulcerative colitis (UC). We used factor analysis and Pearson correlation test to identify candidate questions for inclusion, Wilcoxon rank-sum test to examine responsiveness of the PROBE to changes in disease activity, and test-retest reliability assessments in patients with stable disease activity. We also compared the PROBE to the Short Inflammatory Bowel Disease Questionnaire to assess construct validity.RESULTS:A total of 4,854 patients (64% CD, 36% UC) completed surveys with 6 items included in the final PROBE. Compared with baseline there was a significant decrease in PROBE scores at follow-up among patients who experienced a flare for UC (25.0 vs 22.2, P = 0.001) and CD (23.1 vs 21.0, P < 0.001). Among patients with stable disease activity, Cronbach alpha was 0.87 in CD and 0.82 in UC. The PROBE correlated well with the Short Inflammatory Bowel Disease Questionnaire in CD (r = 0.88) and UC (r = 0.86).DISCUSSION:We created a novel measure to assess QoL in patients with IBD using publicly available survey items. This new PROBE can be used to facilitate clinical care, clinical and epidemiological research, and quality improvement.

description: INTRODUCTION:We conducted a cohort study on the impact of obesity on disease activity and Patient-Reported Outcomes Measurement Information System (PROMIS) measures in the inflammatory bowel disease (IBD) Partners cohort.METHODS:We performed a cross-sectional and longitudinal study within IBD Partners, an internet-based cohort of >15,000 patients living with Crohn's disease (CD) and ulcerative colitis (UC). We included adult patients with IBD, with recorded body mass index (BMI), with at least 6 months of follow-up, excluding patients with BMI < 18.5 kg/m2. We evaluated the independent effect of World Health Organization classes of obesity on risk of clinical relapse or persistent disease activity (using validated disease activity indexes) and PROMIS measures, using multivariate logistic regression and linear regression, respectively.RESULTS:We included 7,296 patients with IBD (4,748 patients with CD, 19.5% obese; 2,548 patients with UC with intact colon, 20.3% obese). Obesity was independently, and in a dose-dependent fashion, associated with an increased risk of persistent disease activity or relapse in both patients with CD (class II or III obesity vs normal BMI: adjusted odds ratio, 1.86; 95% confidence interval, 1.30-2.68) and UC (adjusted odds ratio, 2.97; 95% confidence interval, 1.75-5.17). Obesity was also independently associated with higher anxiety, depression, fatigue, pain, and inferior social function scores in patients with CD and UC at baseline and with worsening depression, fatigue, pain, and social function in patients with CD on longitudinal assessment.DISCUSSION:Obesity at baseline is independently associated with worsening disease activity and PROMIS measures in patients with IBD.

Insensitivity of spin dynamics to the orbital angular momentum transferred from twisted light to extended semiconductors

description: We study the spin dynamics of carriers due to the Rashba interaction in semiconductor quantum disks and wells after excitation with light with orbital angular momentum. We find that although twisted light transfers orbital angular momentum to the excited carriers and the Rashba interaction conserves their total angular momentum, the resulting electronic spin dynamics is essentially the same for excitation with light with orbital angular momentum $l=+|l|$ and $l=-|l|$. The differences between cases with different values of $|l|$ are due to the excitation of states with slightly different energies and not to the different angular momenta per se, and vanish for samples with large radii where a $k$-space quasi-continuum limit can be established. These findings apply not only to the Rashba interaction but also to all other envelope-function approximation spin-orbit Hamiltonians like the Dresselhaus coupling.

description: In Galactic halo stars, sulphur has been shown to behave like other $α$-elements, but until now, no comprehensive studies have been done on this element in stars of other galaxies. Here, we use high-resolution ESO VLT/FLAMES/GIRAFFE spectra to determine sulphur abundances for 85 stars in the Sculptor dwarf spheroidal galaxy, covering the metallicity range $-2.5\leq \text{[Fe/H]} \leq-0.8$. The abundances are derived from the S~I triplet at 9213, 9228, and 9238~Å. These lines have been shown to be sensitive to departure from local thermodynamic equilibrium, i.e. NLTE effects. Therefore, we present new NLTE corrections for a grid of stellar parameters covering those of the target stars. The NLTE-corrected sulphur abundances in Sculptor show the same behaviour as other $α$-elements in that galaxy (such as Mg, Si, and Ca). At lower metallicities ($\text{[Fe/H]}\lesssim-2$) the abundances are consistent with a plateau at $\text{[S/Fe]}\approx+0.16$, similar to what is observed in the Galactic halo, $\text{[S/Fe]}\approx+0.2$. With increasing [Fe/H], the [S/Fe] ratio declines, reaching negative values at $\text{[Fe/H]}\gtrsim-1.5$. The sample also shows an increase in [S/Mg] with [Fe/H], most probably because of enrichment from Type Ia supernovae.

Understanding Vaccine Hesitancy: Three Essays on the Role of Risk, Trust and Cognitive Characteristics in Vaccine Acceptance
Creators: name: Martinelli, Mauro
Publisher: name: Universit� degli studi di Trento
Year: 2022

description: Vaccine prophylaxis can undoubtedly be classified among the most important medical discoveries of the last century. The World Health Organization estimates that each year vaccinations prevent between two and three million deaths. Despite vaccines? safety and effectiveness, vaccine hesitancy, the delay or refusal of vaccines despite their availability, is a re-emerging issue in high income countries. In this thesis I examine this issue pre- and post-COVID-19 pandemic, investigating the main predictors of vaccine hesitancy and highlighting the cognitive processes involved in individual's decision-making. In the theoretical section, I rely on contributions from sociology, economics and public health studies to build a framework enlightening the most relevant predictors of vaccine acceptance, the perceived risk of infectious diseases and the trust in the vaccination process. Through recent development in cognitive sciences, I reframe the issue showing the importance of considering the way individuals perceive, process and retrieve information in developing an informed analysis of vaccine acceptance. In the first empirical chapter, I investigate whether it is possible to identify subgroups in the population characterized by different world-views based on different patterns of the relationship between perceived risk and trust measures. I further assess whether such partitioning hides different levels of vaccine acceptance and whether it also entails a mean of social stratification. In the second empirical chapter I further explore how certain cognitive processes, analytic and intuitive cognition, might be connected to a differential in vaccine acceptance. Furthermore, I highlight individuals? qualitatively complex perceptions of risk, and I suggest how enhancing the attention on cognitive processes and affective concerns might be a key to addressing vaccine hesitancy. In the third empirical chapter, I investigate vaccine hesitancy during the COVID-19 pandemic. I exploit rich comparative longitudinal data and analyze the association between risk perceptions, trust, and willingness to be vaccinated at three different levels: between individuals, between countries and within countries over time. In this chapter, I underline the importance of disentangling the main relationships of this thesis at different levels of analysis, and stress that vaccine acceptance is a multifaceted topic that could involve issues far beyond its own boundaries.

Alternative Uses of CZTS Thin Films for Energy Harvesting
Creators: name: Mustaffa, Muhammad Ubaidah Syafiq
Publisher: name: Universit� degli studi di Trento
Year: 2021

description: The search for renewable energy resources and ways to harvest them has become a global mainstream topic among researchers nowadays, with solar cells and thermoelectric generators among the energy harvesting technologies currently being researched in vast. CZTS (Cu2ZnSnS4), a p-type semiconducting material initially researched to replace copper indium gallium selenide (CIGS) as the light absorbing layer in thin film solar cells, was studied in this doctoral work for alternative uses in energy harvesting. This work aims to systemically investigate the prospects of CZTS to be used as hole transport layers and thermoelectric generators. CZTS thin film was successfully fabricated using a versatile approach involving hot-injection synthesis of CZTS nanoparticles ink followed by spin coating and thermal treatment. Results obtained revealed the possibility to fine control CZTS thin film fabrication based on ink concentration and spin. Besides that, thermal treatment temperature was found to affect the film?s overall properties, where an increase in thermal treatment temperature improved the degree of crystallinity and electrical properties. In addition, a phase change going from less stable cubic and wurtzite structures to a more stable tetragonal structure was also observed. Furthermore, CZTS was found to be a good candidate to replace the commonly used organic hole transport layer in perovskite solar cells, with potentials in improving performance and stability. In addition, CZTS also possessed good transport properties to be a potential p-type material in a thermoelectric generator, with the preliminary performance of fabricated CZTS/AZO thermoelectric generator showing a maximum power output of ~350 nW at ~170 K?T. These findings provide new perspectives for CZTS in energy harvesting applications, despite the struggle in its development as the absorber layer in thin film solar cells. Besides providing a deeper understanding of CZTS and its vast possibilities in energy harvesting applications, promising future research stemming from this work is also limitless, reinventing ways in material studies, in search of alternative applications which may be of benefit.
Optimal Strategies for Antenna Array Design in Advanced Radar and Communications Systems through Convex Optimization
Creators: name: Bui, Le Trong Phuoc
Publisher: name: Universit� degli studi di Trento
Year: 2021

description: In this dissertation, convex programming (CP ) as applied to antenna array synthesis is proposed as a methodology for the optimal synthesis of phased array antennas, and timed/pulsed array antenna as well. In particular, array antenna synthesis in frequency and time domain is formulated as an optimization problem for different types of architectures, systems, and applications in the CP paradigm. In addition, the CP-based optimization has shown great performance with efficient computation for a variety of canonical array synthesis problems due to its convexity property. Furthermore, the jointly satisfying geometrical and operation constraints are also presented because nowadays applications require unconventional array antennas able to guarantee high performance requirements. Therefore, the introduction of optimal synthesis methodologies for the unconventional array is shown for different applications. In this framework, the thesis is aimed to study and develop innovative CP -based methodologies for the optimal synthesis of the unconventional array antennas (e.g., sub-arrayed, wide-band, reconfigure, timed arrays) for next-generation radar and wireless communication systems. A number of examples, including some requirements/constraints and realistic scenarios will be taken into account in order to numerically validate the proposed methodologies when considering both ideal and realistic antenna models.

description: With the use of long-term numerical simulations, we study the evolution and orbital behavior of cometary nuclei in cold Kuiper belt-like debris disks under the gravitational influence of dwarf planets (DPs); we carry out these simulations with and without the presence of a Neptune-like giant planet. This exploratory study shows that in the absence of a giant planet, 10 DPs are enough to induce strong radial and vertical heating on the orbits of belt particles. On the other hand, the presence of a giant planet close to the debris disk, acts as a stability agent reducing the radial and vertical heating. With enough DPs, even in the presence of a Neptune-like giant planet some radial heating remains; this heating grows steadily, re-filling resonances otherwise empty of cometary nuclei. Specifically for the solar system, this secular process seems to be able to provide material that, through resonant chaotic diffusion, increase the rate of new comets spiraling into the inner planetary system, but only if more than the $\sim10$ known DP sized objects exist in the trans-Neptunian region.

Some questions regarding groups of automorphisms of primary trees
Creators: name: Di Domenico, Elena
Publisher: name: Universit� degli studi di Trento
Year: 2022

description: Groups acting on p-adic trees have been well studied over the past decades since they represent a source of examples with interesting properties in group theory. Groups with intermediate growth or counterexamples to the General Burnside Problem can be found inside this class of groups. In this thesis we analyze some properties concerning the structures of two families of groups acting over primary regular rooted trees, i.e. regular rooted trees such that every vertex has a number of descendants equal to a power of a prime. These two families are the GGS-groups acting over the p^n-adic tree and the p-Basilica groups, a generalization of the Basilica group over the p-adic tree for a prime p. A GGS-group over the p^n-adic tree is defined by a vector e whose components are elements in Z/p^nZ. Depending on the defining vector of the GGS-group, we determine which of them are branch. We reduce our study to the fractal GGS-groups, since the non-fractal ones cannot be branch. We prove that all of them, except the ones acting over the 2^n-adic tree whose defining vectors have only one invertible component in position 2^{n-1}, are weakly regular branch. The GGS-groups with constant defining vector are weakly regular branch but not branch. For the other GGS-groups, we prove that they are all regular branch with some small exceptions for which the question is still open. The p-Basilica groups are weakly branch but not branch for any prime p. These provide the first examples of groups with these properties that are super strongly fractal. For this class of groups we also study other problems. We show that they have the p-congruence subgroup property but not the congruence subgroup property nor the weak congruence subgroup property, providing the first examples of weakly branch groups with such properties. We compute the orders of the congruence quotients of these groups, which enables us to determine the Hausdorff dimensions of the p-Basilica groups. Lastly, we show that the p-Basilica groups do not possess maximal subgroups of infinite index and that they have infinitely many non-normal maximal subgroups.

Continual Object Learning
Creators: name: Erculiani, Luca
Publisher: name: Universit� degli studi di Trento
Year: 2021

description: This work focuses on building frameworks to strengthen the relation between human and machine learning. This is achieved by proposing a new category of algorithms and a new theory to formalize the perception and categorizationof objects. For what concerns the algorithmic part, we developed a series of procedures to perform Interactive Continuous Open World learning from the point of view of a single user. As for humans, the input of the algorithms are continuous streams of visual information (sequences of frames), that enable the extraction of richer representations by exploiting the persistence of the same object in the input data. Our approaches are able to incrementally learn and recognize collections of objects, starting from emph{zero} knowledge, and organizing them in a hierarchy that follows the will of the user. We then present a novel Knowledge Representation theory that formalizes the property of our setting and enables the learning over it. The theory is based on the notion of separating the visual representation of objects from the semantic meaning associated with them. This distinction enables to treat both instances and classes of objects as being elements of the same kind, as well as allowing for dynamically rearranging objects according to the needs of the user. The whole framework is gradually introduced through the entire thesis and is coupled with an extensive series of experiments to demonstrate its working principles. The experiments focus also on demonstrating the role of a developmental learning policy, in which new objects are regularly introduced, enabling both an increase in recognition performance while reducing the amount of supervision provided by the user.
Evidence for L-dependence generated by channel coupling: O16 scattering from C12 at 115.9 Mev

description: The inclusion of strong coupling to states of projectile and target nuclei for 115.9 MeV \nuc{16}{O} scattering from \nuc{12}{C} leads to an S-matrix which, when subject to $S_{L} \rightarrow V(r) $ inversion, yields highly undulatory local potentials. Previous work has shown that explicitly $L$-dependent non-undulatory potentials are equivalent to undulatory $L$-independent potentials with the same S-matrix. Here we show that $L$-independent equivalents for certain simple model $L$-dependent potentials exhibit undulatory features qualitatively similar to those arising from channel coupling for 115.9 MeV \nuc{16}{O} scattering from \nuc{12}{C}. We discuss the relevance to the question of $L$-dependence as a generic property of nucleus-nucleus interactions.

Subjects: International relations

description: Ebrahim Raisi won the Iran’s presidential elections from June 18, 2021, and he became the sixth president of the country. The newly elected president in his inaugurational speech outlined the main vectors and priorities of Iran’s political, economic and social development. Ebrahim Raisi determined two major priorities of Iran’s foreign policy: improvement of relations with neighboring countries (1) and expansion of communication with states in Asia, most importantly China and Russia (2). The messages voiced by the newly elected president was assessed by experts and international relations specialists as the rethinking of Iran’s foreign policy and start of the new era. Ebrahim Raisi and his team soon started the implementation of the aforesaid priorities. This is evidenced by the summit held on August 28 in Baghdad, which on its’ part can also serve as a starting point for improvement of relations between Iran and Arab countries. In addition, the summit held in Dushanbe on September 17, where the Shanghai Cooperation Organization approved official Tehran's application to join the alliance, can be considered as one of the most recent achievements of Iran’s foreign policy. The study will analyze the latest achievements, as well as the existing challenges with regards to neighborhood, regional and international politics. Based on the topic of the research it is important for us to study the main priorities and vectors of Iran’s foreign policy, in order to be able to determine its future trends for the coming years.

description: Background: High levels of patient activation (having the knowledge, skills, and confidence to effectively manage one's care), have been associated with improved outcomes in many chronic conditions. There have been few studies of the effects of activation in patients with inflammatory bowel disease (IBD). We performed a large, prospective Internet-based study to assess the relationship between patient activation level and clinical remission in patients with Crohn's disease or ulcerative colitis. Methods: We administered the Patient Activation Measure (Insignia Health) to 1486 cohort participants. Patients completed a follow-up survey within 13 months (median, 189 days). We collected demographic and clinical data; anxiety and depression were assessed using Patient-Reported Outcomes Measurement Information System instruments. We used bivariate analyses and multivariable logistic regression to identify characteristics associated with low or high patient activation and to evaluate the association between levels of patient activation and subsequent disease activity. Results: Higher anxiety (adjusted odds ratio [aOR], 0.32; 95% confidence interval [CI], 0.29-0.36) and depression (aOR, 0.33; 95% CI, 0.29- 0.37) scores were associated with a decreased odds of high patient activation. After we adjusted for education status, smoking, medication use, and other confounders, we found that patients with high activation at baseline were more likely to be in clinical remission during the follow-up period (aOR, 1.71; 95% CI, 1.20-2.45). Conclusions: In a large, prospective Internet-based cohort of patients with IBD, we found a strong association between patient activation and clinical remission. These findings suggest that patient activation affects disease outcomes.

description: Background: Variation in care is common in medical practice. Reducing variation in care is shown to improve quality and increase favorable outcomes in chronic diseases. We sought to identify factors associated with variation in care in children with newly diagnosed Crohn's disease (CD). Methods: Prospectively collected data from a 28-site multicenter inception CD cohort were analyzed for variations in diagnostic modalities, treatment, and follow-up monitoring practices, along with complicated disease outcomes over 3 years in 1046 children. Generalized linear mixed effects models were used to investigate the intercenter variations in each outcome variable. Results: The mean age at diagnosis was 12 years, and 25.9% were nonwhite. The number of participants ranged from 5 to 112 per site. No variation existed in the initial diagnostic approach. When medication exposure was analyzed, steroid exposure varied from 28.6% to 96.9% (P < 0.01) within 90 days, but variation was not significant over a 3-year period (P = 0.13). Early anti-tumor necrosis factor (anti-TNF) exposure (within 90 days) varied from 2.1% to 65.7% (P < 0.01), but variation was not significant over a 3-year period (P > 0.99). Use of immunomodulators (IMs) varied among centers both within 90 days (P < 0.01) and during 3 years of follow-up (P < 0.01). A significant variation was seen at the geographic level with follow-up small bowel imaging and colonoscopy surveillance after initial therapy. Conclusions: Intercenter variation in care was seen with the initial use of steroids and anti-TNF, but there was no difference in total 3-year exposure to these drugs. Variation in the initiation and long-term use of IMs was significant among sites, but further research with objective measures is needed to explain this variation of care. Small bowel imaging or repeat colonoscopy in CD patients was not uniformly performed across sites. As our data show the widespread existence of variation in care and disease monitoring at geographic levels among pediatric CD patients, future implementation of various practice strategies may help reduce the variation in care.
