description: The candidate PeVatron MGRO J1908+06, which shows a hard spectrum beyond 100 TeV, is one of the most peculiar $γ$-ray sources in the Galactic plane. Its complex morphology and some possible counterparts spatially related with the VHE emission region, preclude to distinguish between a hadronic or leptonic nature of the $γ$-ray emission. In this paper we illustrate a new multiwavelength analysis of MGRO J1908+06, with the aim to shed light on its nature and the origin of its ultra high-energy emission. We performed an analysis of the $^{12}$CO and $^{13}$CO molecular line emission demonstrating the presence of dense molecular clouds spatially correlated with the source region. We also analyzed 12-years of Fermi-LAT data between 10 GeV and 1 TeV finding a counterpart with a hard spectrum ($Γ\sim 1.6$). Our reanalysis of XMM-Newton data allowed us to put a more stringent constraint on the X-ray flux from this source. We demonstrate that a single accelerator cannot explain the whole set of multiwavelength data, regardless of whether it accelerates protons or electrons, but a 2-zone model is needed to explain the emission from MGRO J1908+06. The VHE emission seems most likely the superposition of a TeV PWN powered by PSR J1907+0602, in the southern part, and of the interaction between the supernova remnant G40.5-0.5 and the molecular clouds towards the northern region.

Publisher: name: University of British Columbia

description: In this thesis we introduce Non-Standard Methods, in particular the use of hyperfinite difference equations, to the study of space-time random processes. We obtain a new existence theorem in the spirit of Keisler (1984) for the one dimensional heat equation forced non-linearly by white noise. We obtain several new results on the sample path properties of the Critical Branching Measure Diffusion, and show that in one dimension it has a density which satisfies a non-linearly forced heat equation. We also obtain results on the dimension of the support of the Fleming-Viot Process.

description: Graphene oxide (GO) is reduced by Joule heating using in-situ transmission electron microscopy (TEM). The approach allows the simultaneous study of GO conductivity by electrical measurements and of its composition and structural properties throughout the reduction process by TEM, electron diffraction and electron energy-loss spectroscopy. The small changes of GO properties observed at low applied electric currents are attributed to the promotion of diffusion processes. The actual reduction process starts from an applied power density of about 2 1014 Wm-3 and occurs in a highly uniform and localized manner. The conductivity increases more than 4 orders of magnitude reaching a value of 3 103 Sm-1 with a final O content of less than 1%. We discuss differences between the reduction by thermal annealing and Joule heating.
Keynote: Operational Risks and Fast Frequency Control in Future Low-Inertia Power Systems (slides)
Creators: Prof. Igor Kuzle
Publisher: name: IEEE
Year: 2023

Environmental concerns are leading to the proliferation of inverter-coupled renewable energy systems (RES), which are rapidly replacing conventional fossil fuel power plants. This has significant implications for the inertia of the power system, since RES does not normally exhibit rotational inertia.

However, the inertia of the system has become more variable over time and is highly dependent on the current power generation mix. At the same time, the increasing variability of demand due to new loads such as electric vehicles and electric heaters reduces the overall predictability of demand.

Most of these loads are also connected through an inverter. As a result of the high penetration of power electronics connected generation and loads, the nature of the dynamics of modern electric power systems has changed, and their operation has become a challenge that requires new approaches to monitoring and control.

The presentation aims to develop new approaches for monitoring and controlling the operational risks of future low-inertia power systems, focusing on the inertial frequency response and fast frequency control, as well as a number of possible technologies and solutions that can be used to improve the frequency response of the system after disturbances.

description: Bias stress degradation in conjugated polymer field-effect transistors is a fundamental problem in these disordered materials and can be traced back to interactions of the material with environmental species,1,2,3 as well as fabrication-induced defects.4,5 However, the effect of the end groups of the polymer gate dielectric and the associated dipole-induced disorder on bias stress stability has not been studied so far in high-performing n-type materials, such as N2200.6,7 In this work, the performance metrics of N2200 transistors are examined with respect to dielectrics with different end groups (Cytop-M and Cytop-S8). We hypothesize that the polar end groups would lead to increased dipole-induced disorder, and worse performance.1,9,10 The long-time annealing scheme at lower temperatures used in the paper is assumed to lead to better crystallization by allowing the crystalline domains to reorganize in the presence of the solvent.11 It is hypothesized that the higher crystallinity could narrow down the range at which energy carriers are induced and thus decrease the gate dependence of the mobility. The results show that the dielectric end groups do not influence the bias stress stability of N2200 transistors. However, long annealing times result in a dramatic improvement in bias stress stability, with the most stable devices having a mobility that is only weakly dependent on or independent of gate voltage.

Slides for: A Walk Through Image Deblurring: From Model-Based to Generative Restoration
Creators: Dr. Mauricio Delbracio
Publisher: name: IEEE
Year: 2023

SPS Webinar, March 29, 2023, Dr. Mauricio Delbracio
Image deblurring has seen tremendous progress in recent years mostly coming hand-in-hand with the success of deep neural networks. Greater computational power, reliable and accessible training frameworks and large amounts of data have enabled deep image processing models that exceed or are on par with those conceived through careful and artisan modeling. During this talk I will present our recent work on image deblurring with a focus on two distinct scenarios.  First, I will introduce Polyblur, a highly efficient blind restoration method for removing mild blur in natural images. Polyblur estimates slight image blur and compensates for it by combining multiple applications of the estimated blur allowing processing of a 12MP photo on a modern mobile phone in a fraction of a second. In the second part of the talk, I will discuss how to train deep image enhancement models for improved realism in restored images. I will present an alternative approach using a conditional diffusion model to stochastically refine the output of a deterministic predictor capable of producing realistic results. To conclude this talk, I will showcase the newly introduced Unblur feature in the Google Pixel 7 Pro.

title: The Graph Isomorphism Problem and the GI-Completeness of Selected Problems from Context-Free Grammars and Rewrite Systems
Creators: name: Fink Amores, Michael Christian
Publisher: name: Universitätsbibliothek der Ludwig-Maximilians-Universität München
Year: 2021

description: Graph isomorphisms are adjacency and label (equivalence class) preserving one-to-one correspondences between vertex sets of possibly labelled graphs. The graph isomorphism problem is then the task of deciding whether two given graphs are isomorphic or not and basis of complexity class GI, containing all problems with polynomial reduction to former problem. We highlight history and state of the art research on graph isomorphism related problems, with special focus on categorisation of GI in the complexity hierarchy and its relation to the unsolved P = NP problem, where strong theoretic and heuristic evidence suggests that GI is NP-intermediate. The core of the thesis is study of GI-completeness of selected problems from context-free grammars and term rewriting systems. We show polynomial equivalence of the graph isomorphism problem and decision problems on context-free and regular grammars, involving grammar isomorphisms and isomorphic strict interpretations, describing bijective mappings between nonterminals and terminals of different symbol sets. Grammar concepts are specialised to term rewriting systems, formalising substitution based on a function/variable symbol term model. Isomorphism on such finite structures involve local, on a per rule basis, and global rewriting of respective symbol sets, including arbitrary combinations. Completely local term rewriting system isomorphism can be determined in polynomial time by introduction of local templates, subject to different restrictions. Explicit pseudocode algorithms are subsequently provided to support those claims. In contrast, different graph encodings are used to prove that global rewriting of atleast one symbol set already leads to GI-completeness of the related decision problem.

description: We investigate the feasibility of a high statistics experiment to search for invisible decay modes in nuclear gamma cascades using 200 kg of %36 Cs(Tl) scintillators that are presently available at Texas A\&M. The experiment aims to search for missing energy by robustly establishing the absence of a photon in a well identified gamma cascade. We report on the experimental demonstration of the energy resolution necessary for this search. Prior explorations of this detector concept focused on baryonically coupled physics that could be emitted in $E_2$ transitions. We point out that this protocol can also search for particles that are coupled to photons by searching for the conversion of a photon produced in a gamma cascade into a hidden particle. Examples of these processes include the oscillation of a photon into a hidden photon and the conversion of a photon into an axion-like-particle either in the presence of a magnetic field or via the Primakoff process. This proof-of-concept apparatus appears to have the ability to search for hitherto unconstrained baryonically coupled scalars and pseudoscalars produced in $E_0$ and $M_0$ transitions. If successfully implemented, this experiment serves as a pathfinder for a larger detector with greater containment that can thoroughly probe the existence of new particles with mass below 4 MeV that lie in the poorly constrained supernova ``trapping window'' that exists between 100 keV and 30 MeV.

The static local magnetization as well as the low-frequency spin dynamics, probed via the nuclear spin-lattice relaxation rate 1/T_1, were explored from the low to the high field limit and at temperatures from the quantum regime (k_B T << J) up to the classical regime (k_B T >> J). The experimental data show very good agreement with quantum Monte Carlo calculations over the complete range of parameters investigated. Close to the critical field, as derived from static experiments, a pronounced maximum in 1/T_1 is found which we interpret as the finite-temperature manifestation of a diverging density of zero-energy magnetic excitations at the field-driven quantum critical point.

Abstract: Nowadays both digital and analog electronics are reaching fundamental limits that will require revolutionary approaches to satisfy the power/bandwidth requirements of the next generation of data-driven applications.
In the first part of the talk, analog and digital signal processing will be compared in terms of power efficiency by highlighting the presence of a thermodynamic upper-bound which relates dynamic range, bandwidth and power dissipation. To circumvent this limit, in the second part of the talk, the quantized-analog signal processing will be introduced. In such approach, analog and digital domains are merged together in a more fluid scenario compared to traditional mixed-signal circuits avoiding the needs of rigid interfaces such as analog-to-digital and digital-to-analog converters.
It will be shown that the quantized-analog signal processing leads to superior power efficiency and flexibility compared to its analog counterpart and it represents a good candidate for the development of a new generation of mixed signal integrated circuits.  The effectiveness of the proposed solutions will be demonstrated through simulations and measurement results on RF-analog front-ends.
Model-independent constraints on reionization from large-scale CMB polarization
Creators: name: Mortonson, Michael J.
name: Hu, Wayne
Publisher: name: arXiv
Year: 2007
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: On large angular scales, the polarization of the CMB contains information about the evolution of the average ionization during the epoch of reionization. Interpretation of the polarization spectrum usually requires the assumption of a fixed functional form for the evolution, e.g. instantaneous reionization. We develop a model-independent method where a small set of principal components completely encapsulate the effects of reionization on the large-angle E-mode polarization for any reionization history within an adjustable range in redshift. Using Markov Chain Monte Carlo methods, we apply this approach to both the 3-year WMAP data and simulated future data. WMAP data constrain two principal components of the reionization history, approximately corresponding to the total optical depth and the difference between the contributions to the optical depth at high and low redshifts. The optical depth is consistent with the constraint found in previous analyses of WMAP data that assume instantaneous reionization, with only slightly larger uncertainty due to the expanded set of models. Using the principal component approach, WMAP data also place a 95% CL upper limit of 0.08 on the contribution to the optical depth from redshifts z>20. With improvements in polarization sensitivity and foreground modeling, approximately five of the principal components can ultimately be measured. Constraints on the principal components, which probe the entire reionization history, can test models of reionization, provide model-independent constraints on the optical depth, and detect signatures of high-redshift reionization.

A comparative study of stability conditions in dynamical systems, cobweb models, and differential delay equations
Creators: name: Pang, Yeuk Yi
Publisher: name: University of British Columbia
Year: 2010

description: In the study of ordinary differential equations (ODE), a wealth of time has been spent studying dynamical systems. Because of this, much is known about the behaviour of such systems and many methods have been developed to further aid in their analysis. Through comparisons and the construction of actual parallels, this thesis attempts to show how this knowledge of dynamical systems can also be useful in the study of cobweb models and differential delay equations (DDE). Concentration is placed on the development of methods for stability analysis, with general introductions to stability analysis in dynamical systems, cobweb models and differential delay systems. A special parallel is drawn between Hopf-type bifurcation in dynamical systems and Ailwright bifurcation in cobweb models; while the construction of equivalent dynamical systems for S-convertible DDE is presented and stability analysis is carried out for several special examples.

description: We study the issue of symmetries and associated Ward-like identities in the context of two-particle-irreducible (2PI) functional techniques for abelian gauge theories. In the 2PI framework, the $n$-point proper vertices of the theory can be obtained in various different ways which, although equivalent in the exact theory, differ in general at finite approximation order. We derive generalized (2PI) Ward identities for these various $n$-point functions and show that such identities are exactly satisfied at any approximation order in 2PI QED. In particular, we show that 2PI-resummed vertex functions, i.e. field-derivatives of the so-called 2PI-resummed effective action, exactly satisfy standard Ward identities. We identify another set of $n$-point functions in the 2PI framework which exactly satisfy the standard Ward identities at any approximation order. These are obtained as field-derivatives of the two-point function $\bcG^{-1}[ϕ]$, which defines the extremum of the 2PI effective action. We point out that the latter is not constrained by the underlying symmetry. As a consequence, the well-known fact that the corresponding gauge-field polarization tensor is not transverse in momentum space for generic approximations does not constitute a violation of (2PI) Ward identities. More generally, our analysis demonstrates that approximation schemes based on 2PI functional techniques respect all the Ward identities associated with the underlying abelian gauge symmetry. Our results apply to arbitrary linearly realized global symmetries as well.

description: In this work, we revisit the non-minimally coupled Higgs Inflation scenario and investigate its observational viability in light of the current Cosmic Microwave Background, Baryon Acoustic Oscillation and type Ia Supernovae data. We explore the effects of the Coleman-Weinberg approximation to the Higgs potential in the primordial universe, connecting the predictions for the Lagrangian parameters at inflationary scales to the electroweak observables through Renormalization Group methods at two-loop order. As the main result, we find that observations on the electroweak scale are in disagreement with the constraints obtained from the cosmological data sets used in the analysis. Specifically, an $\approx 8σ$-discrepancy between the inflationary parameters and the electroweak value of the top quark mass is found, which suggests that a significant deviation from the scenario analysed is required by the cosmological data.

description: We investigate the electronic structures of some defective boron nitride nanotubes (BNNTs) under transverse electric fields within density-functional theory. (16,0) BNNTs with antisite, carbon substitution, single vacancy, and Stone-Wales 5775 defects are studied. Under transverse electric fields, the band gaps of the defective BNNTs are reduced, similar to the pristine ones. The energy levels of the defect states vary with the transverse electric field directions, due to the different electrostatic potential shift at the defect sites induced by the electric fields. Therefore, besides electronic structure and optical property engineering, the transverse electric field can be used to identify the defect positions in BNNTs.

Slides for: SPS Webinar, 13 March 2023, Dr. Donald Williamson.
Deep learning has helped make speech processing applications, such as speech recognition, speech synthesis and speech translation, more prevalent in everyday life. It has also advanced the field of speech enhancement, where it has become the state-of-the-art approach to removing unwanted sounds. Successful speech enhancement can have profound impacts on how people communicate with each other and through electronic devices, so it is an area of research that must be addressed. Although several deep learning approaches have been developed, which focus on novel architectures and optimization strategies, there remains other aspects of the problem that have not been adequately investigated.

In this talk, we will discuss how human perception should be leveraged to further address problems within speech enhancement, and we will discuss how human perception can be predicted and used to improve noise reduction. Additionally, we will provide highlights of my work in complex-domain speech enhancement, which encouraged full signal reconstruction.

description: By adding a GLPT3 (third-order Görling-Levy perturbation theory, or KS-MP3) term E3 to the XYG7 form for a double hybrid, we are able to bring down WTMAD2 (weighted total mean absolute deviation) for the very large and chemically diverse GMTKN55 benchmark to an unprecedented 1.17 kcal/mol, competitive with much costlier composite wavefunction ab initio approaches. Intriguingly: (a) the introduction of E3 makes an empirical dispersion correction redundant; (b) GGA or mGGA semilocal correlation functionals offer no advantage over LDA in this framework; (c) if a dispersion correction is retained, then simple Slater exchange leads to no significant loss in accuracy. It is possible to create a 6-parameter functional with WTMAD2=1.42 that has no post-LDA DFT components and no dispersion correction in the final energy.

description: In two recent reactions by Belle producing $D\bar D$ and $D\bar D^*$ meson pairs, peaks above threshold have been measured in the differential cross sections, possibly indicating new resonances in these channels. We want to study such reactions from the point of view that the $D$ meson pairs are produced from already known or predicted resonances below threshold. Our study shows that the peak in the $D\bar D^*$ production is not likely to be caused by the X(3872) resonance, but the peak seen in $D\bar D$ invariant mass can be well described if the $D\bar D$ pair comes from the already predicted scalar X(3700) resonance.

Creators: name: Capalbo, Donatella
Publisher: name: Università degli Studi di Napoli Federico II

description: Endocrine system exerts relevant effects on multiple organs and tissues. Pleiotropic and redundant functions of circulating hormones are due to the various receptors expressed on multiple target cells. Moreover, receptors of circulating hormones share common transducing elements with receptors of many other molecules. Consequently, endocrine system participate to an integrated network of mediators that communicate and coordinate responsive cells to achive effective functions in an appropriate fashion. The presence of such a complex interplay contribute to unravel previously unappreciated functions of circulating hormones and the mechanisms of coordination and integration of several pathways.
An example of this interplay is the complex interaction between endocrine and immune system. Cytokines and growth factors, in fact,  after their binding to cell-surface receptos, activate common intracytoplasmatic signaling molecules. In the recent years the description of complex phenotypes, in which immunodeficiency and growth failure were associated at a different extent, greatly contributed to define how several signaling molecules play a role in both systems. As well as immunodeficiency, autoimmune diseases represent a unique model to study interactions between endocrine and immune systems.
Cardiovascular system also represents a  biological system higly sensitive to the effects of circulating hormones as suggested by the presence of several cardiovascular and metabolic alterations found in many endocrine diseases. In fact, patient with growth hormone deficiency  as well as thyroid dysfunction, may present an increased morbidity due to cardiovascular events and an increased incidence of atherosclerosis.
Aim of this project was to evaluate physiological and pathological implications of these complex molecular interactions on paediatric endocrinopathies starting from complex phenotype involving endocrine and other biological systems.
To this aim, we started from the study of 3 model of complex diseases:
•	The model of autoimmune diseases
•	The model of Growth Hormone (GH) Deficiency (GHD)
•	The model of Congenital Hypothyroidism (CH)
Moreover, during the study of patients affected with Growth Hormone  and thyroid disorders we also identified new genetic causes of GH deficiency and hyperthyroidism, highlithing new insights in the genetics of endocrine diseases,  as described in the last chapter of the thesis.

description: We summarize the intuitive connection between deformations of parton distributions in impact parameter space and single-spin asymmetries. Lattice results for the $x^2$-moment of the twist-3 polarized parton distribution $g_2(x)$ are used to estimate the average transverse force acting on the active quark in SIDIS in the instant after being struck by the virtual photon.

description: Over 91% of the Paraguayan Upper Paraná Atlantic Forest has been cleared and the Gran Chaco is the fastest disappearing habitat on the continent. One of the compounding issues for conservation in Paraguay is the lack of knowledge of the importance of nature amongst the population. Fundación Para La Tierra (PLT) began the country’s first Eco-Club program, “Voces de la Naturaleza” (Voices of Nature), in 2016. Three of the curriculums participatory lessons focus on primate conservation. These lessons formed the basis of PLT’s Atlantic Forest education programme in 2018 when the team began visiting 22 schools around San Rafael (Tekoha Guasu). To date 26 schools (1,500+ children) across two political departments and four districts have participated in this programme which is now entering its 6th year. The biggest challenges have included the COVID-19 pandemic and the logistics and costs involved in reaching rural and remote schools. Though it is too soon to record observable behavioural change ongoing monitoring over the six year period indicates that children remember the information gained through the participatory methods for several years. We believe that the main reasons for the success of this programme are the collaborations that we have built with the teachers of the schools based on open communication and mutual respect. Though costs can be an issue when beginning, or running, a long-term project we recommend that potential educators not be put off trying and that a lot of good can be achieved with a small amount of funding.

description: This article presents a mixed-method study exploring interdisciplinary collaboration at Castelo Branco Polytechnic University during the 2022-2023 academic year. The collaboration involves an English for Specific Purposes (ESP) teacher and a content teacher, examining receptiveness to collaboration and the impact of Integrated Content and Language in Higher Education (ICLHE). The study focuses on first-year undergraduate students in the fashion and textile design course, utilising questionnaires developed with Social Cognitive Theory (SCT) and Expectancy-Value Theory (EVT) for validity and reliability. The study provides a broad context based on research on interdisciplinary collaboration and ICLHE. Preliminary qualitative and quantitative analyses reveal significant challenges for students in technical language, underscoring the need for targeted support. The findings indicate a generally positive attitude towards ICLHE and collaborative teaching methods. Additionally, the study highlights how students\\\' self-efficacy, expectancy beliefs, and task values influence their receptiveness and learning outcomes in interdisciplinary settings. The results emphasise the importance of clear learning objectives, active engagement, and adequate resources, suggesting that effective interdisciplinary collaboration can enhance technical language learning and overall educational experiences. These insights offer actionable recommendations for improving teaching practices and fostering successful interdisciplinary initiatives in higher education.

On the characterization of equilibria of nonsmooth minimal-time mean field games with state constraints

description: In this paper, we consider a first-order deterministic mean field game model inspired by crowd motion in which agents moving in a given domain aim to reach a given target set in minimal time. To model interaction between agents, we assume that the maximal speed of an agent is bounded as a function of their position and the distribution of other agents. Moreover, we assume that the state of each agent is subject to the constraint of remaining inside the domain of movement at all times, a natural constraint to model walls, columns, fences, hedges, or other kinds of physical barriers at the boundary of the domain. After recalling results on the existence of Lagrangian equilibria for these mean field games and the main difficulties in their analysis due to the presence of state constraints, we show how recent techniques allow us to characterize optimal controls and deduce that equilibria of the game satisfy a system of partial differential equations, known as the mean field game system.

AGENT-BASED METHODOLOGIES FOR FACILITY LOCATION PROBLEMS

description: The high relevance of location problems in the operations research literature arises from their wide spectrum of real applications, including decision optimization
in industrial management, logistics, and territorial planning. Most of these optimization problems fall into the class of NP-hard problems, motivating the search for heuristic and approximated algorithms. Currently, a great interest is being devoted to those optimization approaches yielding a concrete integration with spatial analysis instruments (such as Geographical Information Systems) that provide the user with an easy visualization of input data and optimization results.
Agent-Based computing was recently proposed as an alternative to mathematical programming in order to solve problems whose domains are concurrently distributed,
complex, and heterogeneous, also thanks to the availability of many commercial and open source codes including graphical interfaces for the elements of the problem.
In this paper we propose a general Agent-Based framework for modeling various location problems. Together with its description, we present some computational results confirming the suitability and the effectiveness of the proposed approach.

description: We apply the mathematical technique of factorization of differential operators to two different problems. First we review our results related to the supersymmetry of the Montroll kinks moving onto the microtubule walls as well as mentioning the sine-Gordon model for the microtubule nonlinear excitations. Second, we find analytic expressions for a class of one-parameter solutions of a sort of diffusion equation of Bessel type that is obtained by supersymmetry from the homogeneous form of a simple damped wave equations derived in the works of P.A. Robinson and collaborators for the corticothalamic system. We also present a possible interpretation of the diffusion equation in the brain context

description: In this paper the determination of material properties such as Sieverts' constant (solubility) and diffusivity (transport rate) via so-called gas release experiments is discussed. In order to simulate the time-dependent hydrogen fluxes and concentration profiles efficiently, we make use of an analytical method, namely we provide an analytical solution for the corresponding diffusion equations on a cylindrical specimen and a cylindrical container for three boundary conditions. These conditions occur in three phases -- loading phase, evacuation phase and gas release phase. In the loading phase the specimen is charged with hydrogen assuring a constant partial pressure of hydrogen. Then the gas will be quickly removed by a vacuum pump in the second phase, and finally in the third time interval, the hydrogen is released from the specimen to the gaseous phase, where the pressure increase will be measured by an equipment which is attached to the cylindrical container. The investigated diffusion equation in each phase is a simple homogeneous equation, but due to the complex time-dependent boundary conditions which include the Sieverts' constant and the pressure, we transform the homogeneous equations to the non-homogeneous ones with a zero Dirichlet boundary condition. Compared with the time consuming numerical methods our analytical approach has an advantage that the flux of desorbed hydrogen can be explicitly given and therefore can be evaluated efficiently. Our analytical solution also assures that the time-dependent boundary conditions are exactly satisfied and furthermore that the interaction between specimen and container is correctly taken into account.
