description: An improved standard solar model has been used to calculate the fluxes of standard solar neutrinos. It includes premain sequence evolution, element diffusion, partial ionization effects, and all the possible nuclear reactions between the main elements. It uses updated values for the initial solar element abundances, the solar age, the solar luminosity, the nuclear reaction rates and the radiative opacities. Neither nuclear equilibrium, nor complete ionization are assumed. The calculated solar neutrino fluxes are compared with published results from the four solar neutrino experiments. The calculated $^8$B solar neutrino flux is consistent, within the theoretical and experimental uncertainties, with the solar neutrino observations at Homestake and Kamiokande. The observations suggest that the $^7$Be solar neutrino flux is much smaller than that predicted. However, conclusive evidence for the suppression of the $^7$Be solar neutrino flux will require experiments like BOREXINO and HELLAZ. If the $^7$Be solar neutrino flux is suppressed, it still can be due either to standard physics and astrophysics or neutrino properties beyond the standard electroweak model. Only future neutrino experiments, such as SNO, Superkamiokande, BOREXINO and HELLAZ, will be able to show that the solar neutrino problem is a consequence of neutrino properties beyond the standard electroweak model.

description: We describe a modular rewriting system for translating optimization problems written in a domain-specific language to forms compatible with low-level solver interfaces. Translation is facilitated by reductions, which accept a category of problems and transform instances of that category to equivalent instances of another category. Our system proceeds in two key phases: analysis, in which we attempt to find a suitable solver for a supplied problem, and canonicalization, in which we rewrite the problem in the selected solver's standard form. We implement the described system in version 1.0 of CVXPY, a domain-specific language for mathematical and especially convex optimization. By treating reductions as first-class objects, our method makes it easy to match problems to solvers well-suited for them and to support solvers with a wide variety of standard forms.

description: While Martin Heidegger and the Situationist International exist politically and ideologically opposed, the intersection of historical events, people and ideas creates a framework for investigating their common ground. The relationship between Situationist ideas, the revolutionary Paris events of 1968 and Heideggerian thought contains elements of both philosophical influence and historical connections. As the historical outline demonstrates, Heidegger influenced French philosophy across a variety of dimensions by way of Hebert Marcuse, Kostas Axelos, and Jean-Paul Sartre, all of whom were involved in the French New Left. The pertinence of the connections between Martin Heidegger, French philosophers and the events of May 1968 illuminates the notion that political and intellectual developments emerge shaped by and dependent on context. After exploring the historical connections between Heidegger and French universities and intellectual circles in the 1960s, Heidegger and the Situationist International are examined philosophically in tandem. As both Heidegger and the Situationist International critique the advent of technology divorced from human values, there begins a discussion of some of the most philosophically important topics of our time, including authenticity, freedom, objectification, technology and everyday life.

description: Spectral-spatial classification of hyperspectral images has been the subject of many studies in recent years. In the presence of only very few labeled pixels, this task becomes challenging. In this paper we address the following two research questions: 1) Can a simple neural network with just a single hidden layer achieve state of the art performance in the presence of few labeled pixels? 2) How is the performance of hyperspectral image classification methods affected when using disjoint train and test sets? We give a positive answer to the first question by using three tricks within a very basic shallow Convolutional Neural Network (CNN) architecture: a tailored loss function, and smooth- and label-based data augmentation. The tailored loss function enforces that neighborhood wavelengths have similar contributions to the features generated during training. A new label-based technique here proposed favors selection of pixels in smaller classes, which is beneficial in the presence of very few labeled pixels and skewed class distributions. To address the second question, we introduce a new sampling procedure to generate disjoint train and test set. Then the train set is used to obtain the CNN model, which is then applied to pixels in the test set to estimate their labels. We assess the efficacy of the simple neural network method on five publicly available hyperspectral images. On these images our method significantly outperforms considered baselines. Notably, with just 1% of labeled pixels per class, on these datasets our method achieves an accuracy that goes from 86.42% (challenging dataset) to 99.52% (easy dataset). Furthermore we show that the simple neural network method improves over other baselines in the new challenging supervised setting. Our analysis substantiates the highly beneficial effect of using the entire image (so train and test data) for constructing a model.

Do About Half the Top Quarks at FNAL Come From Gluino Decays?

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We argue that it is possible to make a consistent picture of FNAL data including the production and decay of gluinos and squarks. The additional cross section is several pb, about the size of that for Standard Model (SM) top quark pair production. If the stop squark mass is small enough, about half of the top quarks decay to stop squarks, and the loss of SM top quark pair production rate is compensated by the supersymmetric processes. This behavior is consistent with the reported top quark decay rates in various modes and other aspects of the data, and suggests several other possible decay signatures. This picture can be tested easily with more data, perhaps even with the data in hand, and demonstrates the potential power of a hadron collider to determine supersymmetric parameters. It also has implications for the top mass measurement and the interpretation of the LEP $R_b$ excess.

description: The presence of COVID-19 has affected many industries across the United States, with one of the more prominent industry being workers compensation. With an insurance contingent on the basic concept of a worker within their work environment, the introduction of this contagious illness impacted the industry as a whole. Insurance claims have adjusted: the frequency and severity rates, premium costs, and overall workers compensation loss costs have changed to fit the new socio-economic environment. However, to what extent? As such, this thesis aims to elaborate on three main topics. First, can we better understand the impact of workers compensation claims by analyzing how workers compensation was affected during previous recessions and trend it to the current recession transpiring in the United States. Second, how do less restrictive regulations and social interactions in a state such as Texas impact workers compensation loss costs. Finally, what actions can be taken to mitigate the changes in loss costs and better prepare workers compensation claims for future pandemics. As COVID-19 continues to develop across the United States, workers compensation has been impacted on both a financial and social basis.
Near-infrared and optical broadband surface photometry of 86 face-on disk dominated galaxies. IV. Using color profiles to study stellar and dust content of galaxies

description: The stellar and dust content of spiral galaxies as function of radius has been investigated using near-infrared and optical broadband surface photometry of 86 face-on spiral galaxies. Colors of galaxies correlate with the azimuthally averaged local surface brightness both within and among galaxies, with the lower surface brightness regions being bluer. The colors formed from different passband combinations correlate strongly indicating that they probably arise from the same physical process. A 3D radiative transfer model was developed to calculate the effect of dust absorption and scattering on the luminosity and color profiles of galaxies. Stellar synthesis models were used to investigate the effects of the star formation history and the metallicity on the broadband color profiles. Combining all optical and near-infrared data shows that the color gradients in this sample of face-on galaxies are best explained by a combined stellar age and metallicity gradient across the disk, with the outer regions being on average younger and of lower metallicity. Dust reddening probably plays only a minor role, as the dust models cannot produce reddening profiles that are compatible with the observations. The observed color differences implicate substantial M/L_lambda differences, both within galaxies and among galaxies. The variations are such that the ``missing light'' problem derived from rotation fitting becomes even worse. Late-type galaxies (T>=6) have lower metallicities and are often of younger average age than earlier types and have therefore an entirely different M/L_λin most passbands. The near-infrared passbands are recommended for studies where the M/L_λratios should not vary too much.

description: The status of searches for gravitational microlensing events of the stars in our galaxy and in other galaxies of the Local Group, the interpretation of the results, some theory, and prospects for the future are reviewed. The searches have already unveiled about 100 events, at least two of them caused by binaries, and have already proven to be useful for studies of the Galactic structure. The events detected so far are probably attributable to the effects of ordinary stars, and possibly to sub-stellar brown dwarfs; however a firm conclusion cannot be reached yet because the analysis published to date is based on a total of only 16 events. The current searches, soon to be upgraded, will probably allow determination of the mass function of stars and brown dwarfs in the next few years; these efforts will also provide good statistical information about binary systems, in particular their mass ratios. They may also reveal the nature of dark matter and allow us to detect planets and planetary mass objects.

description: We explore possibilities of gauge coupling unification in left--right symmetric models with non--minimal particle content. In addition to unification we require the absence of anomalies and sufficient proton lifetime. Numerous previously unknown solutions are presented where unification occurs within the latest experimental errors. Solutions exist where the scale of left--right symmetry breaking can be as low as ${\cal O}(TeV)$ or the scale $M_R$ as high as the Planck scale.

title: Analysis and Implementation of Isogeometric Boundary Elements for Electromagnetism
Creators: name: Wolf, Felix
Publisher: name: UNSPECIFIED
Year: 2020

description: This thesis is concerned with the analysis and implementation of an isogeometric boundary element method for electromagnetic problems. After an introduction of fundamental notions, we will introduce the electric field integral equation (EFIE), which is a variational problem for the solution of the electric wave equation under the assumption of constant coefficients. Afterwards, we will review the notion of isogeometric analysis, a technique to conduct higher-order simulations efficiently and without the introduction of geometrical errors. We prove quasi-optimal approximation properties for all trace spaces of the de Rham sequence and show inf-sup stability of the isogeometric discretisation of the EFIE. Following the analysis of the theoretical properties, we discuss algorithmic details. This includes not only a scheme for matrix assembly but also a compression technique tailored to the isogeometric EFIE, which yields dense matrices. The algorithmic approach is then verified through a series of numerical experiments concerned with electromagnetic scattering problems. These behave as theoretically predicted. In the last part, the boundary element method is combined with an eigenvalue solver, a so-called contour integral method. We introduce the algorithm and solve electromagnetic resonance problems numerically, where we will observe that the eigenvalue solver benefits from the high orders of convergence offered by the boundary element approach.

description: We present UV (2300 Ang) images, obtained with the HST Faint Object Camera, of the central 20'' of five galaxies containing circumnuclear star-forming rings. The five galaxies are from a well-defined sample of 103 normal, nearby galaxies we have observed with HST. At the HST resolution (0.05''), the rings break up into discrete star-forming clumps, each composed of many luminous and compact ($R \ltorder 5$ pc) star clusters. These objects are similar to those that have been recently reported in colliding and starburst galaxies, and in several other circumnuclear rings. A large fraction, 15%--50%, of the UV emission originates in these compact clusters. Compact clusters therefore may be the preferred mode of star formation in starburst environments. For one galaxy, NGC 2997, we measure the UV-optical colors of the individual clusters using an archival HST WFPC2 image at 6000 Ang . Comparing the colors and luminosities to starburst population synthesis models, we show that the clusters are less than 100 Myr old and have masses of at least a few $10^3 M_{\odot}$, with some as high as $10^5 M_{\odot}$. The UV extinction to those clusters that are detected in the UV is at most a factor of 10. In NGC 2997, the limits on the masses and the ages of the young clusters indicate that these objects will remain bound and evolve into globular clusters. The luminosity function of the clusters in the rings is similar in shape to those measured for super star clusters in other star-forming galaxies, and extends to luminosities lower by several orders of magnitude. All five of the UV-detected circumnuclear rings occur in barred or weakly barred spiral galaxies of type Sc or earlier. None of the five rings has an active nucleus at its center, arguing against a direct correspondence between circumnuclear star formation and nuclear

Για την συγκέντρωση του ερευνητικού δείγματος ακολουθήθηκε η δειγματοληψία ευκολίας και χιονοστιβάδας. Η στατιστική ανάλυση έγινε μέσω του SPSS. Τα ερευνητικά αποτελέσματα έδειξαν μέτρια επίπεδα συνολικής εργασιακής ικανοποίησης των εκπαιδευτικών και χαμηλά επίπεδα μισθολογικής τους ικανοποίησης. Ικανοποίηση των εκπαιδευτικών από τις μισθολογικές τους απολαβές μπορεί να επηρεάσει την ποιότητα της εκπαίδευσης και να έχει επιρροή στην σχολική επίδοση των μαθητών, αλλά δεν επηρεάζει σε στατιστικά σημαντικό βαθμό την απόδοση των εκπαιδευτικών. Χαμηλότερα επίπεδα μισθολογικής ικανοποίησης εμφανίζουν οι άντρες εκπαιδευτικοί, οι εκπαιδευτικοί μεγαλύτερης ηλικίας και περισσοτέρων ετών προϋπηρεσίας, καθώς επίσης και οι εκπαιδευτικοί που δήλωσαν ότι εργάζονται σε δημόσια σχολεία, αλλά και όσοι δήλωσαν ότι έχουν ένα ή κανένα παιδί.

description: Human action recognition has been one of the most active fields of research in computer vision for last years. Two dimensional action recognition methods are facing serious challenges such as occlusion and missing the third dimension of data. Development of depth sensors has made it feasible to track positions of human body joints over time. This paper proposes a novel method of action recognition which uses temporal 3D skeletal Kinect data. This method introduces the definition of body states and then every action is modeled as a sequence of these states. The learning stage uses Fisher Linear Discriminant Analysis (LDA) to construct discriminant feature space for discriminating the body states. Moreover, this paper suggests the use of the Mahalonobis distance as an appropriate distance metric for the classification of the states of involuntary actions. Hidden Markov Model (HMM) is then used to model the temporal transition between the body states in each action. According to the results, this method significantly outperforms other popular methods, with recognition rate of 88.64% for eight different actions and up to 96.18% for classifying fall actions.
Engineered Sn doped TiO2 bifunctional catalyst for improved hetero-photocatalytic oxidation of arsenite in water

Year: 2022

description: Millions of people worldwide are exposed to arsenic contaminated water. TiO2 photocatalytic oxidation (PCO) of As(III) to the less toxic As(V) which can be easily removed is a challenging process due to several reasons particularly the bandgap limitation and the poor quantum efficiency. Here, a procedure was developed to accurately determine the oxidation rates of As(III) which is challenging. The calculated photon and energy absorption by TiO2 were 36.7 and 44.9 %, respectively. Finally, the quantum efficiency (QE) as a potential measure of the PCO was determined. SnO2@Sn-TiO2 and Sn-TiO2@SnO2 photocatalysts were synthesised and characterised using XRD, Raman, XPS, DRS, LEIS, EDX, HR-TEM, SEM, S-TEM and FTIR. These analyses revealed that at low doping ratios, SnO2 formed the shell of the catalyst (SnO2@Sn-TiO2), whereas higher Sn doping ratio developed a Sn-TiO2 shell alongside a core of SnO2 (Sn-TiO2@SnO2). Increasing Sn-doping resulted in a shift in the conduction and valence band edge energies accompanied with a reduction in the bandgap. The smallest bandgap in 1Sn:1TiO2 (2.87 eV) is linked to the improved electron-hole separation. Sn-TiO2@SnO2 and SnO2@Sn-TiO2 improved the PCO of TiO2 by ∼94 % to 145 %. For the first time, the PCO rate was accurately determined by mounting both adsorbed As(V) (using XPS) and aqueous As(V) (spectrophotometry). TAS experiments showed a long-lived charge carriers in 1Sn:1TiO2. The initial transient absorption signal was ~2 times higher than anatase TiO2, suggesting early timescale (pre-μs) suppression in the electron-hole recombination in 1Sn:1TiO2. The scavenger studies show that the hydroxyl radical (OH.) is the main oxidant. Lastly, the controls of experimental parameters on the PCO of As(III) over 1Sn:1TiO2 were studied. These controls include the distance between the light source and the solution surface which shows a high effect on the photon flux reaching the solution, the QE and PCO rate.
Ultra-high frame rate and high resolution CMOS ISFET arrays for ion imaging

description: For the past few decades, CMOS Ion Sensitive Field Effect Transistors (ISFETs) have been the main enabler in the field of biomedical imaging based on electrochemical sensors. The development of the ISFET has been following the same trend to a photo-diode in optical imagers, whose single device robustness has been well-established over the years. Mass-manufacturing ISFETs in CMOS has set a new trend for incorporating them into arrays to serve as a CMOS Lab-on-Chip (LoC) ion imaging front end, exploring high-resolution spatial-temporal bio-information. As we continuously scale the size of the array while minimising the physical dimensions of each sensor, we also need to consider their readout architectures, to avoid significant compromises on their performances. From an array level, there exists a fundamental trade-off between the resolution of the array and its readout frame rate. In this thesis, we investigate novel system architectures to realise high resolution and high frame rate ISFET arrays on a minimum silicon area, with compensation techniques for CMOS ISFETs non-idealities considered. To start off, we present a system utilising current mode signal processing techniques to minimise the sampling interval between two subsequent pixels, followed by 8 multiplexed current mode 10-bit ADCs for quantisation. The system is implemented in the AMS 0.35 μm CMOS process, operating at 3000 fps for an array size of 128×128, which is the fastest ISFET array reported in the literature. From this perspective, we promote the second generation LoC front-end consisting of a similar current mode readout topology while improving its performance both in mismatch and noise under the TSMC 0.18 μm process. Using row-parallel system architectures, we implement one 8-bit ADC per readout row to deliver a frame rate of 6100 fps with a same array size as before, further elevating the speed record for ISFET arrays. Following this, we propose two innovative approaches focusing on array offset reduction and compensation in a per pixel basis. Each system features a pixel-level offset compensation circuit followed by 8-bit row-parallel ADCs as a part of a global feedback loop. Voltage and current mode architectures are implemented respectively while both can acquire ion interactions for up to 1000 fps with the same array size as before. We conclude this work by applying the designed array for bio-analysis, in particular to discover the spatial-temporal origin of DNA amplifications, and to explore the impact of flow rates with a microfluidics setup, as well as to characterise the short-term dynamics of the ion-selective membranes. We demonstrate an end-to-end high speed and high resolution ion imaging platform that can be used to explore various biomedical-related information from a much wider spectrum.
The tidally induced warping, precession and truncation of accretion discs in binary systems: three-dimensional simulations

description: We present the results of non linear, hydrodynamic simulations, in three dimensions, of the tidal perturbation of accretion discs in binary systems where the orbit is circular and not necessarily coplanar with the disc mid-plane. The accretion discs are assumed to be geometrically thin, and of low mass relative to the stellar mass so that they are governed by thermal pressure and viscosity, but not self-gravity. The parameters that we consider in our models are the ratio of the orbital distance to the disc radius, D/R, the binary mass ratio, the initial inclination angle between the orbit and disc planes and the Mach number in the outer parts of the unperturbed disc. For binary mass ratios of around unity and D/R in the range 3 to 4, we find that the global evolution of the discs is governed primarily by the value of the Mach number. For relatively low Mach numbers (i.e. 10 to 20) we find that the discs develop a mildly warped structure, are tidally truncated, and undergo a near rigid body precession at a rate which is in close agreement with analytical arguments. For higher Mach numbers (approx. 30), the evolution is towards a considerably more warped structure, but the disc none the less maintains itself as a long-lived, coherent entity. Additionally, it is found that the inclination angle between the disc and orbital angular momentum vectors evolves on a longer timescale which is probably the viscous evolution timescale of the disc. The calculations are relevant to a number of observed astrophysical phenomena, including the precession of jets associated with young stars, the high spectral index of some T-Tauri stars, and the light curves of X-ray binaries such as Hercules X-1 which suggest the presence of precessing accretion discs.

description: We introduce a new regularization scheme for Quantum Cosmology in Loop Quantum Gravity (LQG) using the tools of Quantum Reduced Loop Gravity (QRLG). It is obtained considering density matrices for superposition of graphs based on statistical countings of microstates compatible with macroscopic configurations. We call this procedure statistical regularization scheme. In particular, we show how the $μ_0$ and $\barμ$ schemes introduced in Loop Quantum Cosmology (LQC) emerge with specific choices of density matrices. Within this new scheme we compute effective Hamiltonians suitable to describe quantum corrected Friedmann and Bianchi I universes and their leading orders coincide with the corresponding effective LQC Hamiltonians in the $\barμ$ scheme. We compute the next to the leading orders corrections and numerical investigation of the resulting dynamics shows evidence for the emergent-bouncing universe scenario to be a general property of the isotropic sector of QRLG.

description: We investigate the scattering of a spinning test particle by a Kerr black hole within the Mathisson-Papapetrou-Dixon model to linear order in spin. The particle's spin and orbital angular momentum are taken to be aligned with the black hole's spin. Both the particle's mass and spin length are assumed to be small in comparison with the characteristic length scale of the background curvature, in order to avoid backreaction effects. We analytically compute the modifications due to the particle's spin to the scattering angle, the periastron shift, and the condition for capture by the black hole, extending previous results valid for the nonrotating Schwarzschild background. Finally, we discuss how to generalize the present analysis beyond the linear approximation in spin, including spin-squared corrections in the case of a black-hole-like quadrupolar structure for the extended test body.
