description: In the field of Photovoltaic technologies the organic solar cells are particularly attractive because of their ease of processing, mechanical flexibility and potential low cost production techniques. So far, the reported efficiencies are not high enough to allow to be competitive in the market, however with the introduction of new photoactive materials, device architectures and light management structures, the power conversion efficiencies, at laboratory scale, has rapidly reached the 12%, showing a great potential and a bright future for organic solar cells. Nevertheless, in view of commercial products, two main problems are still unresolved: the relatively low performance of the modules and their lifetime. In sight of this, the present Ph.D thesis has a double goal: 1) a better understanding of the relationship between devices performance and photoactive materials structures 2) a deep investigation on device degradation processes, with particular attention on the effects induced by temperature and incident light. As a result, promising approaches to further optimize the polymer’s optoelectrial properties, and thus the corresponding device performance, are proposed. About the lifetime, first the thermal degradation mechanisms involved on the active layer was investigated and it has been demonstrated the role of the other layers and interfaces in the solar cell thermal stability. In this contest an innovative fast capacitance based thermal test has been developed in order to obtain information regarding the limit operating temperature above which the device becomes thermally unstable. In the end, a preliminary study on the photostability issue was carried out demostrating that the photodegradation of organic solar cells not depends just on the photostability of the donor polymer, but is connected also with the composition of the active layer solution and on the interaction with the adjacent layers. Solutions to limit or prevent the devices degradation processes are proposed.

description: Change Detection (CD) is an essential field in remote sensing, with a primary focus on identifying areas of change in bi-temporal image pairs captured at varying intervals of the same region by a satellite. The data annotation process for the CD task is both time-consuming and labor-intensive. To make better use of the scarce labeled data and abundant unlabeled data, we present an adaptive dynamic semi-supervised learning method, AdaSemiCD, to improve the use of pseudo-labels and optimize the training process. Initially, due to the extreme class imbalance inherent in CD, the model is more inclined to focus on the background class, and it is easy to confuse the boundary of the target object. Considering these two points, we develop a measurable evaluation metric for pseudo-labels that enhances the representation of information entropy by class rebalancing and amplification of confusing areas to give a larger weight to prospects change objects. Subsequently, to enhance the reliability of sample-wise pseudo-labels, we introduce the AdaFusion module, which is capable of dynamically identifying the most uncertain region and substituting it with more trustworthy content. Lastly, to ensure better training stability, we introduce the AdaEMA module, which updates the teacher model using only batches of trusted samples. Experimental results from LEVIR-CD, WHU-CD, and CDD datasets validate the efficacy and universality of our proposed adaptive training framework.

description: Nowadays video-assisted lobectomy could be considered an appropriate treatment option for early stage lung cancer patients, as obtaining similar or even better early outcomes when compared to open standard lobectomy. This study was aimed at verifying the long-term impact (three months after surgery) of VATS-lobectomy technique on physical and mental status of patients undergoing lung resection for lung cancer and to compare the physical variation to the one registered after open approach. 
We enrolled patients treated by VATS-lobectomy at our institution since June 2012 to June 2015, comparing the preoperative physical evaluation (in terms of FEV1, DLCO and VO2max) and perceived quality of life (measured using the EORTC questionnaire) to the postoperative values. Moreover we performed a propensity score matching analysis to verify if the physical variation registered after VATS-lobectomy differed from that after  open resection.
We found a three months postoperative reduction of the physical indicators in comparison to the preoperative values (FEV1-variation: -8.3%, DLCO-variation: -12.4%, VO2max-variation: -6.6%). A similar negative trend was found for the psychological indicators, but the only parameter with a significative worsening was the perceived physical functioning (variation: -6.2%).
The propensity score procedure yielded 83 well-matched open and VATS-lobectomy patients. The reductions in FEV1, DLCO and VO2max were similar in both groups (open patients’ reduction: FEV1 -10%, DLCO -11.9%, VO2max -5.5%; VATS patients’ reduction: FEV1 -7.2%, DLCO -10.6%, VO2max -6.9%), with a Cohen effect size < 0.2 for all the comparisons.
In conclusion, VATS-lobectomy influences a reduction of the preoperative functional status three months after the operation, without affecting the postoperative perceived quality of life. Moreover VATS-lobectomy doesn’t offer any advantage in terms of FEV1, DLCO and exercise capacity recovery in comparison to the open approach.

Species and Functional Composition of some Abandoned Fields in the Northern Apennines (Italy). A Detailed Overview with particular Reference to the Habitat 6210 in the EU 92/43 Directive

description: Abandoned croplands can be considered a new category of “scattered elements” of mountain landscapes. To gain deeper understanding of the conservation status (sensu EEC Directive 92/43) of abandoned cropland in the northern Apennines, we coupled the concepts of the social behavior type (SBT) and the functional assessment of plant communities. SBTs refer to behaviour and ecological attributes of species at a given observation level and allow the understanding of the plant community conservation status, while the functional approach may help in predicting changes of species composition along disturbance and stress gradients. We found that topographic and soil conditions drive the species assemblage in pastures after crop abandonment, but long-term abandonment does not lead per se to the recovery of the semi-natural grassland communities deemed worthy of conservation in the EEC Directive. It was mainly due to the lack of appropriate disturbance regimes that allows the spread of dominant tall herbs, which, in turn, reduces the site suitability for subordinate plants. Moreover, their spread fosters the presence of elements such as ruderals and fringe species. We conclude that, these abandoned croplands have a good potential to develop into Habitat of EU Directive but without appropriate management plans they will remain of low representativeness.

description: We consider the generalization of the Araki-Uhlmann formula for relative entropy to Petz-Rényi relative entropy. We compute this entropy for a free scalar field in the Minkowski wedge between the vacuum and a coherent state, as well as for the free chiral current in a thermal state. In contrast to the relative entropy which in these cases only depends on the sympletic form and thus reduces to the classical entropy of a wave packet, the Petz-Rényi relative entropy also depends on the symmetric part of the two-point function and is thus genuinely quantum. We also consider the relation with standard subspaces, where we define the Rényi entropy of a vector and show that it admits an upper bound given by the entropy of the vector.

Models and Solutions of Resource Allocation Problems based on Integer Linear and Nonlinear Programming
Creators: name: Thomopulos, Dimitri <1987>
Publisher: name: Alma Mater Studiorum - Università di Bologna
Year: 2016
Subjects: MAT/09 Ricerca operativa

description: In this thesis we deal with two problems of resource allocation solved through a Mixed-Integer Linear Programming approach and a Mixed-Integer Nonlinear Chance Constraint Programming approach.
In the first part we propose a framework to model general guillotine restrictions in two dimensional cutting problems formulated as Mixed-Integer Linear Programs (MILP). The modeling framework requires a pseudo-polynomial number of variables and constraints, which can be effectively enumerated for medium-size instances. Our modeling of general guillotine cuts is the first one that, once it is implemented within a state of-the-art MIP solver, can tackle instances of challenging size. Our objective is to propose a way of modeling general guillotine cuts via Mixed Integer Linear Programs (MILP), i.e., we do not limit the number of stages (restriction (ii)), nor impose the cuts to be restricted (restriction (iii)). We only ask the cuts to be guillotine ones (restriction (i)). We mainly concentrate our analysis on the Guillotine Two Dimensional Knapsack Problem (G2KP), for which a model, and an exact procedure able to significantly improve the computational performance, are given. 
In the second part we present a Branch-and-Cut algorithm for a class of Nonlinear Chance Constrained Mathematical Optimization Problems with a finite number of scenarios. This class corresponds to the problems that can be reformulated as Deterministic Convex Mixed-Integer Nonlinear Programming problems, but the size of the reformulation is large and quickly becomes impractical as the number of scenarios grows. We apply the Branch-and-Cut algorithm to the Mid-Term Hydro Scheduling Problem, for which we propose a chance-constrained formulation. A computational study using data from ten hydro plants in Greece shows that the proposed methodology solves instances orders of magnitude faster than applying a general-purpose solver for Convex Mixed-Integer Nonlinear Problems to the deterministic reformulation, and scales much better with the number of scenarios.

description: Rare-earth magnets with parent cubic symmetry exhibit unique topological properties. However, the origin of these behaviors remains presently unclear. Here, we develop minimal models for Dirac semimetals (DSMs) with accidental band crossings and higher-order topology in cubic systems, incorporating candidate magnetic order to analyze bulk, surface, and hinge state characteristics. In certain cubic-symmetric DSMs, we identify an effective Z2 chiral symmetry which significantly impacts surface and hinge-localized states. Our results highlight distinct features in surface state dispersions, Fermi arcs, polarization dependence, and band splitting that correlate with photoemission data in rare-earth monopnictides. We also suggest candidate materials and experimental tests for further validation. These findings advance our understanding of surface states in rare-earth magnets with parent cubic symmetries and illuminate the role of DSM physics in these systems.

description: This paper presents an experimental approach of using crowdsourcing to test controlled vocabularies for digital collections of cultural objects. For a digital humanities initiative project, Project Andvari, which is intended to create a digital portal of early medieval northern European artifacts, it was recognized that there was a need to develop a semantically structured iconographic thesaurus to describe the iconographic content of distributed artefactual collections from a variety of contributing institutions. This paper discusses a workflow of planning and development process of controlled vocabularies for the project and a testing process of the vocabularies to determine both the usability of controlled vocabularies and the feasibility of quality assurance approach. This paper demonstrates an applicability of crowdsourcing in developing controlled vocabularies.
Pure Designation. Deleuze’s Reading of Hjelmslev in The Time-Image
Creators: name: Schreel, Louis
Publisher: name: Università degli Studi di Milano
Year: 2016

description: In the second chapter of The Time-Image, Deleuze addresses the conditions of possibility of a semiology of cinema. These conditions depend on the relations between cinema and language: under what conditions can cinematic images and signs be understood as a language? In other words, (how) can cinematic images and signs be inscribed in the discursive plane of the signifiable? Discussing Christian Metz’s semiological approach of cinema, Deleuze argues that the structural conditions of linguistics and of post-Saussurian semiology cannot adequately render intelligible the specificity of cinematic semiosis. Drawing on Louis Hjelmslev’s semiotics, Deleuze redefines the specificity of a relation of designation distinct from a relation of signification (strictly linguistic), a specificity that concerns the fact that the designative relation is antecedent and heterogeneous to any signifying relation. Put differently, the very constitution of the sign is redefined: in opposition to semiology, semiotics becomes the study of images and signs as (1) being independent of language in general and (2) expressing a “non-language material”. This article explicates the importance of Hjelmslev’s semiotic theory in The Time-Image by offering a detailed account of the constitution of the sign in Hjelmslev’s Prolegomena to a Theory of Language and by tracing Deleuze’s earlier appreciation of Hjelmslev in Anti-Oedipus and its intricate relation to his appreciation of Jean-François Lyotard’s theory of designation in Discourse Figure.

description: In this work, we derive working equations for the Linear Response pair Coupled Cluster Doubles (LR-pCCD) ansatz and its extension to singles (S), LR-pCCD+S. These methods allow us to compute electronic excitation energies and transition dipole moments based on a pCCD reference function. We benchmark the LR-pCCD+S model against the {linear response} coupled-cluster singles and doubles method for modeling electronic spectra (excitation energies and transition dipole moments) of the BH, \ce{H2O}, \ce{H2CO}, and furan molecules. We also analyze the effect of orbital optimization within pCCD on the resulting LR-pCCD+S transition dipole moments {and oscillator strengths} and perform a statistical error analysis. We show that the LR-pCCD+S method can correctly reproduce the transition dipole moments features, thus representing a reliable and cost-effective alternative to standard, more expensive electronic structure methods for modeling electronic spectra of simple molecules. Specifically, the proposed models require only mean-field-like computational cost, while excited-state properties may approach the CCSD level of accuracy. Moreover, we demonstrate the capability of our model to simulate electronic transitions with non-negligible contributions of double excitations and the electronic spectra of polyenes of various chain lengths, for which standard electronic structure methods perform purely.

G-SharP: Globally Shared Kernel with Pruning for Efficient CNNs
Publisher: name: IEEE Signal Processing Society
Year: 2024

description: Filter Decomposition (FD) methods have gained traction in compressing large neural networks by dividing weights into basis and coefficients. Recent advancements have focused on reducing weight redundancy by sharing either basis or coefficients stage-wise. However, traditional sharing approaches have overlooked the potential of sharing basis on a network-wide scale. In this study, we introduce an FD technique called G-SharP that elevates performance by using globally shared kernels throughout the network. To bolster the efficacy of G-SharP, we unveil a novel batch normalization-based coefficient pruning strategy aiming to boost computational efficiency. Comprehensive evaluations show that our method notably diminishes computational demands and model size while incurring only a slight decline in performance. On benchmarks like CIFAR-10, ImageNet, PASCAL-VOC, and MS-COCO, G-SharP achieves significant reductions in model dimensions and FLOPs yet maintains accuracy levels akin to the original uncompressed models. Notably, G-SharP surpasses numerous leading lightweight models, striking a commendable balance between precision and efficiency.

description: Endgame (1957), considered by many as Samuel Beckett’s major work, stands out as a “terminal” play, a play in which the characters live in an absolute present, devoid of any idea of future and completely disconnected from the world of memories, which are so far away as to seem mere hallucinations. How, then, should these characters live in a universe that is so close to its end? By waiting, Beckett suggests; by waiting, paradoxically, for things to take their own course.

description: Presented is a methodology to explicitly identify and account for cloud-free satellite measurements below a sensor’s measurement detection level. These low signals can often be found in satellite observations of minor atmospheric species with weak spectral signals (e.g., ammonia (NH3)). Not accounting for these non-detects can high-bias averaged measurements in locations that exhibit conditions below the detection limit of the sensor. The approach taken here is to utilize the information content from the satellite signal to explicitly identify non-detects and then account for them with a consistent approach. The methodology is applied to the CrIS Fast Physical Retrieval (CFPR) ammonia product and results in a more realistic averaged dataset under conditions where there are a significant number of non-detects. These results show that in larger emission source regions (i.e., surface values > 7.5 ppbv) the non-detects occur less than 5% of the time and have a relatively small impact (decreases by less than 5%) on the gridded averaged values (e.g., annual ammonia source regions). However, in regions that have low ammonia concentration amounts (i.e., surface values < 1 ppbv) the fraction of non-detects can be greater than 70%, and accounting for these values can decrease annual gridded averaged values by over 50% and make the distributions closer to what is expected based on surface station observations.

description: This article examines Adorno’s non-identity thinking and the moral role of mimesis. On the one hand, Adorno criticises Kant’s moral theory, revealing the heteronomy of morality and the untruth of subjective freedom, on the other he defends the utopistic urge of the “transcendental”, moving from finitude and imperfection. Adorno opposes to the bourgeois personality neither a naïve return to nature, nor a getting rid of the subject, but the individual as differentiated coexistence of self and otherness, spirit and nature.

Factors associated with waist circumference in UK adults’ population
Creators: name: Albaloul, Anwar Hamoud
Publisher: name: Imperial College London
Year: 2022

description: Introduction: Waist circumference is significantly associated metabolic disease morbidity and mortality, independent of BMI. Characteristics of dietary intakes, such as overall dietary pattern, dietary fibre and fat intake, are recognised as factors associated with waist circumference. Common genetic variants have also been found to explain variation in population susceptibility to having a high waist circumference. However, it is not known whether dietary intakes modify associations between genetic and waist circumference. Therefore, this study's primary aim is to investigate how diet and genetics affect waist circumference across the UK adult’s population. This study secondary aim is to investigate the effect of dietary intake on genetic predisposition to having high waist circumference. Method: This cross-sectional study analysed data from the Airwave Health Monitoring Study, a UK-based occupational cohort study that included 45,000 participants (from 2004 to 2018). Diet quality was evaluated based on Dietary Approaches to Stop Hypertension. The genetic risk score associated with waist circumference (GRSwaist) was derived from 91 WC-associated single nucleotide polymorphisms. Multivariable regression models were used to determine the associations between diet, genetics and waist circumference. An interaction term was introduced to multivariable regression models to determine the effect of dietary intake on genetic predisposition to waist circumference. This study was replicated using 442,583 participants from the UK-Biobank Cohort study. Results: Groups with a larger waist circumference (female > 80 cm, males > 94 cm) was positively associated with HbA1c% (OR= 1.08, 95%CI =1.0,1.1, P-value= 0.02). DASH-diet score and fibre intake were negatively associated with waist circumference. A positive association was found between GRSwaist and waist circumference. No interaction was observed between diet scores and genetic predisposition to having high waist circumference. The replicated analysis on the UK-Biobank population was consistent with the Airwave study findings. Conclusion: Waist circumference was positively associated with HbA1c%. Dietary patterns and genetic risk scores are significant factors associated with waist circumference in the UK adults’ population. Dietary intake does not modify the influence of genetic on waist circumference.
Galleria mellonella: an infection model for the Mycobacterium tuberculosis complex
Creators: name: Asai, Masanori
Publisher: name: Imperial College London

description: Tuberculosis (TB), caused by Mycobacterium tuberculosis (MTB), is a leading cause of global infectious disease mortality. Advancement in TB research relies heavily on the use of animal infection models. However, all models have their limitations serving as bottlenecks in research, underlining the need for alternatives. This thesis describes the characterisation of an infection model for the MTB complex (MTBC) in Galleria mellonella (Gm) – the greater wax moth. Time-kill assays of Gm challenged with Mycobacterium bovis BCG (BCG), double auxotrophic MTB (SAMTB), or MTB (H37Rv) demonstrated that Gm can differentiate virulence between members of the MTBC, with establishment of a persistent (BCG) or proliferative (SAMTB and H37Rv) infection. A Gm-MTBC microscopy interaction study revealed internalisation of mycobacteria by phagocytic haemocytes (analogous to mammalian neutrophils and macrophages) as early as 1 hour post-infection. A non-replicative bacilli phenotype (lipid accumulation) was observed only in BCG infection. A histological study of infected Gm identified the formation of granuloma-like structures, containing non-replicative bacilli (loss of Ziehl-Neelsen-staining for SAMTB and H37Rv alone). The utility of Gm as a screen for antimycobacterial drug toxicity/efficacy and comparative MTB virulence was demonstrated using clinically relevant compounds, and isogenic MTB mutants (ΔphoP and ΔdosR), respectively. Proteomic and gene expression analysis of BCG infected Gm, identified immune responses indicative of phagocytosis, formation of granuloma-like structures, and secretion of antimicrobial peptides. Furthermore, proof-of-concept models of ex vivo granuloma-like structures and real-time in vivo drug screening are presented. These results indicate that Gm is a viable alternative infection model for TB being capable of mimicking critical aspects of the disease, and can be used to assess comparative MTB virulence, and as 6 a low-medium throughput antimycobacterial drug screen. The adoption and continued development of this model has the potential to substantially reduce/replace the use of animals in TB research.
Numerical methods for model predictive control
Creators: name: McInerney, Ian Scott
Publisher: name: Imperial College London
Year: 2021

description: There has been an increased interest in controlling complex systems using Model Predictive Control (MPC). However, the use of resource-constrained computing platforms in these systems has slowed the adoption of MPC. This thesis focuses on increasing the efficiency of numerical methods for MPC in terms of resource usage and solution time, while also simplifying the design process. We first show how block Toeplitz operators can be used to link the linear MPC matrices to the transfer function of the predicted system, resulting in horizon-independent bounds on the condition number of the condensed Hessian and the upper iteration bound for the Fast Gradient Method (FGM). We derive a horizon-independent preconditioner that produces up to a 9x speedup for the FGM while reducing the preconditioner computation time by up to 50,000x compared to an existing preconditioner. We propose a new method for computing the minimum number of fractional bits needed to ensure the FGM with fixed-point arithmetic is stable, with an example showing decreases of up to 77% in resource usage and 50% in the computational energy when using this method on a Field Programmable Gate Array. Finally, we present a framework using the derivative-free Mesh Adaptive Direct Search method to solve nonlinear MPC problems with non-differentiable features or quantized variables without the need for complex or costly reformulations. We augment the system dynamics with additional states to compute the Lagrange cost term and the violation of the path constraints along the state trajectory, and then perform a structured search of the input space using a single-shooting simulation of the system dynamics. We demonstrate this framework on a robust Goddard rocket problem with a non-differentiable cost and a quantized thrust input, where we achieve an altitude within 40m of the target, while other methods are unable to get closer than 180m.

description: Macrocnemus bassanii è un rettile diapside del Triassico medio appartenente al gruppo dei Protorosauria. Le sue principali caratteristiche sono gli arti posteriori molto più lunghi di quelli anteriori e il collo rigido e allungato. Questo lavoro ha lo scopo di chiarire alcuni aspetti ancora poco noti della sua anatomia, in particolare la struttura della regione nasale, la mobilità del quadrato e l’eventuale presenza di placche sternali e di epifisi. Inoltre si vuole comprendere la funzione del collo allungato, che è il principale enigma di questo gruppo di rettili. La sua particolare struttura è probabilmente correlata al tipo di locomozione di  Macrocnemus bassanii. Ricostruire il tipo di locomozione è fondamentale per stabilire qual era il ruolo ecologico di questo rettile. Si esaminano infine i rapporti filogenetici tra Macrocnemus bassanii e gli altri taxa appartenenti al gruppo dei protorosauria.
description: Macrocnemus bassanii is a Middle Trias diapsid reptile that belongs to the group of the Protorosauria. Its main features are the elongated stiff neck and the hindlimbs which are much longer than the forelimbs. The aim of this study is to clarify some aspects of its anatomy that are still controversial, like the structure of the nasal region, the mobility of the quadrate, and the existence of sternal plates and epiphysis.  Furthermore it is very important to understand the function of the neck. The neck is the major conundrum of this group of reptiles. Its particular structure is probably correlated to the kind of locomotion of Macrocnemus bassanii. The reconstruction of the kind of locomotion is fundamental to establish what the ecological role of this reptile was. Finally the phylogenetic relationships between Macrocnemus bassanii and the other taxa of the Protorosauria are studied.

description: The present PhD thesis summarizes the results of experimental activities carried out on the production and characterization of cast aluminum alloys and Al-based nanocomposites for room and high temperature applications. Two quaternary Al-Si-Cu-Mg alloys (A354 and C355) were studied, aiming to investigate the effect of chemical composition, solidification rate and heat treatment condition on the tensile and fatigue behavior at room and high temperature. Heat treatment optimization of A354 alloy was carried out. The overaging behavior of A354 and C355 alloys was compared to that of A356 (Al-Si-Mg) alloy, in order to evaluate the thermal stability of the alloys. As a result, the concurrent presence of Cu and Mg confers, by precipitation hardening, enhanced mechanical properties and higher thermal stability in comparison to the traditional Al-Si-Mg alloy. A preliminary study aimed to evaluate the effect of Molybdenum addition on A354 overaging response was also carried out. Enhanced mechanical properties after long-term overaging were registered in A354-0.3wt.%Mo alloy, in comparison to the base A354. Casting techniques for the production of Al-matrix composites were implemented at the laboratory scale. The stir-casting method assisted with ultrasonic treatment and in situ reactive casting were applied to produce Al2O3-A356 micro/nanocomposites and ZrB2-A356 composites, respectively. Friction Stir Process (FSP) was evaluated as possible solid state processing route to: (i) enhance Al2O3 nanoparticles distribution in a semisolid processed AA2024-based nanocomposite, and (ii) directly distribute Al2O3 nanoparticles into AA7075 alloy at the solid state. Experimental results highlighted difficulties in obtaining an even distribution of nanoparticles, by both liquid and semi-soli state routes, due to the low wettability of nano-sized ceramic reinforcement. The application of FSP led to enhanced nanoparticles distribution, mitigation of casting defects associated to nanoparticles addition (porosity, nanoparticles clusters) and microstructural homogenization, thus allowing to better exploit nanoparticles strengthening effect.

description: Contactless energy transfer (CET) systems are gaining increasing interest in the automatic machinery industries. For this reason, circuit equivalent networks of CET systems considered in the literature are introduced with emphasis on their industrial applicability. The main operating principles and the required compensating networks, along with different topologies of power supplies optimised for wireless powering, are discussed. The analysis of the wireless transfer, at the maximum efficiency, of high power levels shows that, in the kHz range, highly coupled inductive links are needed and soft-switching power sources required. The employment of CET units in controlled systems requires combining a link for data communication with the wireless power channel. At low frequencies, capacitive and inductive couplings are integrated in a unique platform to implement the wireless data and power links, respectively. Differently, at UHF, an increased data channel transfer efficiency is made possible by exploiting auto-resonant structures, such as split-ring resonators instead of capacitances, one at each far-end side of the link. The design procedure of a power CET system, including the dc/ac converter, a rotary transformer and its windings, is discussed and the results presented. A different version of a WPT system, which involves multiple transmitting coils and a sliding receiver, is also presented. A low frequency RFID capacitive data link is then combined with the rotary CET unit to provide the temperature feedback of a controlled system, wherein the rectifying part of a passive tag is exploited to simultaneously power and read a temperature probe. Subsequently, a split-ring based near-field UHF data link is designed to ensure an improved temperature detection in terms of accuracy and resolution. The sensor readout is performed at the transmitter side by measuring the reflected power by the load rectifier.
Collisional Transport of Solar Wind Plasma during its Journey from the Sun to the Earth

description: Parker Solar Probe (PSP) is the first spacecraft to dive deep into the solar corona, making the first-ever direct measurements of the plasma within the corona and offering unprecedented observations of solar wind plasma in its nascent form. In their journey outward from the Sun, the streams that make up solar wind plasmas interact, expand, and evolve in a number of different ways. Previous theoretical work has shown that coulomb collisions are one of the many factors that dictate the thermodynamic properties that distinguish different kinds of solar wind. Plasma instruments onboard the PSP spacecraft, making up the Solar Wind Electrons, Alphas, and Protons (SWEAP) suite, provide an opportunity to further test and investigate this well-known collisional hypothesis by identifying solar wind plasma streams that are also measured by other spacecraft such as Solar Orbiter and Wind during suitable conjunctions. These multi-point observations will be compared to collisional predictions to evaluate the evolution of plasma distributions as they travel through the inner heliosphere. This work examines the degree to which collisional transport can explain the radial evolution of plasma parameters within 1 au.

L’estetica di Paolo VI e il progetto di nuova evangelizzazione degli artisti
Creators: name: De Caro, Eugenio
Publisher: name: Università degli Studi di Milano
Year: 2016

description: The paper focuses on the theory of art outlined by Giovanni Battista Montini (1897-1978) – usually known as Pope Paul VI (position held between 1963 and 1978) – investigated from an aesthetic point of view. The author refers also to less-known manuscripts outlined by G.B. Montini since the first decays of the XX century and then substantially confirmed by his subsequent speeches with the role of Archbishop of Milan (1954-1963) and later Pope. The paper allows to clarify the theoretical roots of the famous request addressed in 1964 to contemporary artists to enter into an alliance with the Church aimed at discovering the most genuine and spiritual needs of contemporary mankind. It focuses therefore not only on the Paul VI’s theory of holy art, but properly on his very conception of art and of the artists’ mission considered into a broader sense. The artist is ultimately regarded as a kind of prototype of contemporary Christian man.

Exploring Atomic Systems Using a Relativistic IMSRG Scheme
Creators: name: Patel, Hrishikesh
Publisher: name: The University of British Columbia
Year: 2023

description: In this work, we propose to use In-Medium Similarity Renormalisation Group (IMSRG) scheme to study the precise structure of atomic systems with a Dirac-Hartree Fock (DHF) reference frame. IMSRG was developed as a many-body method in the field of nuclear physics to decouple degrees of freedom in highly correlated Hamiltonians. DHF, on the other hand, is a well-established meanfield approach in the field of atomic physics where relativistic effects for multi-electron species are calculated using a mean-field potential. Precise agreement with experiment and prediction power are essential in the field of atomic physics. In this work, we provide a way to combine these two methods to accurately calculate ground states of atomic systems. We provide calculations comparable to state-of-the-art benchmarks for closed shell atomic systems and some proof-of-concept calculations for open shell atoms which have so far eluded most ab-initio methods in the field. We also address some key limitations of our method and outline steps needed to overcome them.
