description: To complete tasks faster, developers often have to sacrifice the quality of the software. Such compromised practice results in the increasing burden to developers in future development. The metaphor, technical debt, describes such practice. Prior research has illustrated the negative impact of technical debt, and many researchers investigated how developers deal with a certain type of technical debt. However, few studies focused on the removal of different types of technical debt in practice. To fill this gap, we use the introduction and removal of different types of self-admitted technical debt (i.e., SATD) in 7 deep learning frameworks as an example. This is because deep learning frameworks are some of the most important software systems today due to their prevalent use in life-impacting deep learning applications. Moreover, the field of the development of different deep learning frameworks is the same, which enables us to find common behaviors on the removal of different types of technical debt across projects. By mining the file history of these frameworks, we find that design debt is introduced the most along the development process. As for the removal of technical debt, we find that requirement debt is removed the most, and design debt is removed the fastest. Most of test debt, design debt, and requirement debt are removed by the developers who introduced them. Based on the introduction and removal of different types of technical debt, we discuss the evolution of the frequencies of different types of technical debt to depict the unresolved sub-optimal trade-offs or decisions that are confronted by developers along the development process. We also discuss the removal patterns of different types of technical debt, highlight future research directions, and provide recommendations for practitioners.
Feedback Control and Characterization of a Microcantilever Using Optical Radiation Pressure

description: We describe a method for feedback-regulation of a microcantilever's response using optical radiation pressure. One laser measures the position of the cantilever and another laser applies a force that is a phase-shifted function of that position. The force is due solely to the momentum of the photons in the laser. The feedback changes the microcantilever's effective quality factor Qeff and effective temperature Teff. Reduction of both Qeff and Teff by more than a factor of 15 is demonstrated. Additionally, we suggest a method for determination of a microcantilever's spring constant using the known force exerted on it by radiation pressure.

description: The Country Research Agenda for Jordan was developed over the span of nine months as part of the first year of the Education Research in Conflict and Protracted Crisis (ERICC) program. ERICC is a large-scale FCDO-funded, three-year program to generate new, rigorous research evidence on the most effective approaches to providing education in conflict and protracted crisis contexts. Ultimately, the program aims to expand the global research base in this area and provide relevant evidence to policy-makers and other education stakeholders to support necessary reform in education delivery in conflict- and crisis-affected contexts. To this end, ERICC is being implemented in six conflict-affected countries – Jordan, Bangladesh (Cox’s Bazar), and Nigeria in the first cohort and South Sudan, Lebanon and Syria in the second cohort. The research agenda presented here highlights ERICC’s co-constructed national research priorities within Jordan, the rationale and factors that inform these priorities, and research plans to enact the agenda moving forward.

description: In this work we report on the effects of short-range correlations upon the matrix elements of neutrinoless double beta decay. We focus on the calculation of the matrix elements of the neutrino-mass mode of neutrinoless double beta decays of 48Ca and 76Ge. The nuclear-structure components of the calculation, that is the participant nuclear wave functions, have been calculated in the shell-model scheme for 48Ca and in the proton-neutron quasiparticle random-phase approximation (pnQRPA) scheme for 76Ge. We compare the traditional approach of using the Jastrow correlation function with the more complete scheme of the unitary correlation operator method (UCOM). Our results indicate that the Jastrow method vastly exaggerates the effects of short-range correlations on the neutrinoless double beta decay nuclear matrix elements.

Hydromagnetic Instability in Differentially Rotating Flows

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We study the stability of a compressible differentially rotating flows in the presence of the magnetic field, and we show that the compressibility profoundly alters the previous results for a magnetized incompressible flow. The necessary condition of newly found instability can be easily satisfied in various flows in laboratory and astrophysical conditions and reads $B_{s} B_ϕ Ω' \neq 0$ where $B_{s}$ and $B_ϕ$ are the radial and azimuthal components of the magnetic field, $Ω' = d Ω/ds$ with $s$ being the cylindrical radius. Contrary to the well-known magnetorotational instability that occurs only if $Ω$ decreases with $s$, the instability considered in this paper may occur at any sign of $Ω'$. The instability can operate even in a very strong magnetic field which entirely suppresses the standard magnetorotational instability. The growth time of instability can be as short as few rotation periods.

description: We construct finite element subspaces of the space of symmetric tensors with square-integrable divergence on a three-dimensional domain. These spaces can be used to approximate the stress field in the classical Hellinger--Reissner mixed formulation of the elasticty equations, when standard discontinous finite element spaces are used to approximate the displacement field. These finite element spaces are defined with respect to an arbitrary simplicial triangulation of the domain, and there is one for each positive value of the polynomial degree used for the displacements. For each degree, these provide a stable finite element discretization. The construction of the spaces is closely tied to discretizations of the elasticity complex, and can be viewed as the three-dimensional analogue of the triangular element family for plane elasticity previously proposed by Arnold and Winther.

description: Στόχος της παρούσας διατριβής είναι η διερεύνηση της σχέσης μεταξύ της αποτελεσματικότητας των γεωργικών εκμεταλλεύσεων και της γεωργικής βιοποικιλότητας. Επιπλέον παράγοντες που διερευνούνται είναι: η εργασία, το μέγεθος της εκμετάλλευσης, τα λιπάσματα, τα φυτοφάρμακα, η απόσταση των αγροτεμαχίων από την οικία, ο πολυτεμαχισμός και η υγεία του παραγωγού. Η αποτελεσματικότητα των εκμεταλλεύσεων υπολογίζεται με την βοήθεια της Περιβάλλουσας Ανάλυσης Δεδομένων (Data Envelopment Analysis-DEA), ενώ η διερεύνηση των παραγόντων που την επηρεάζουν πραγματοποιείται με πολλαπλή γραμμική παλινδρόμηση (multiple regression). Η ανάλυση εφαρμόζεται σε ένα σύνολο δεδομένων επιπέδου εκμετάλλευσης για τις γεωργικές εκμεταλλεύσεις σιτηρών (σιτάρι, κριθάρι, βρώμη) στο Νομό Λάρισας. Η έρευνα έδειξε ότι οι εκμεταλλεύσεις που έχουν μικρό δείκτη γεωργικής βιοποικιλότητας είναι περισσότερο αποτελεσματικές και ότι η υγεία του παραγωγού αποτελεί καθοριστικό παράγοντα για την αποτελεσματικότητα των γεωργικών εκμεταλλεύσεων, με τις εκμεταλλεύσεις, των οποίων οι αρχηγοί παρουσιάζουν μεγαλύτερη συχνότητα εμφάνισης προβλημάτων στη μέση, να είναι και οι λιγότερο αποτελεσματικές.
description: The aim of this study is to analyze the impact of agricultural biodiversity on farm efficiency. Labor, farm size, fertilizers, herbicides, fragmentation, distance of parcels from home and farmers’ health are also studied. A non-parametric data envelopment analysis (DEA) technique is employed to calculate the efficiency scores, while a multiple regression model is applied to investigate the factors that have an impact on farm efficiency. The analysis is applied on farm-level data of cereal farms in province of Larissa. The study shows that farms, which have a small agricultural biodiversity index, are more efficient and that farmers’ health is a determinant of farm efficiency. Farms, whose heads face low back pain more frequently, are less efficient.

description: A possible setup for the experimental verification of linear Breit-Wheeler pair creation of electrons and positrons in photon-photon collisions is studied theoretically. It combines highly energetic bremsstrahlung photons, which are assumed to be generated by an incident beam of GeV electrons penetrating through a high-$Z$ target, with keV photons from an X-ray laser field, which is described as a focused Gaussian pulse. We discuss the dependencies of the pair yields on the incident electron energy, target thickness, laser parameters, and collision geometry. It is shown that, for suitable conditions which are nowadays in reach at X-ray laser facilities, the resulting number of created particles seems to be well accessible for enabling the first experimental observation of the linear Breit-Wheeler process $γγ\to e^+e^-$.

description: This volume covers Leg 79 of the cruises of the Drilling Vessel Glomar Challenger. The continental margin off Morocco has long been recognized as an ideal location to learn about the early history of rifting in the central North Atlantic, because its later history of sediment starvation enables access to the early deposits by deep sea drilling. Deep Sea Drilling Project Legs 41 and 50 were devoted to the study of the deep sea basin off Morocco, and Leg 79 was designed to study the adjacent continental margin. The four sites drilled during Leg 79 were located in a stepwise series down the Mazagan Escarpment in order to reconstruct the stratigraphy and depositional history of the deeper part of the continental margin. This approach proved to be successful, and an almost complete Jurassic section was encountered at one of the drilled sites. Since the Mazagan Plateau is capped by a carbonate platform, Leg 79 also provided a unique opportunity to study the development of the outer deep margin of a carbonate platform; such information is not obtainable from the Mesozoic carbonate platforms which rim the eastern North American margin because of their thick sedimentary cover. Leg 79 began on April 15, 1981, when Glomar Challenger steamed out of Las Palmas toward the Mazagan Plateau, and ended in Brest, France on May 30, 45 days later. Thirty-four days were spent at 4 drill sites.

description: We present measurements of differential cross sections and analyzing powers for the elastic 2H(~d; d)d scattering process. The data were obtained using a 130 MeV polarized deuteron beam. Cross sections and spin observables of the elastic scattering process were measured at the AGOR facility at KVI using two independent setups, namely BINA and BBS. The data harvest at setups are in excellent agreement with each other and allowed us to carry out a thorough systematic analysis to provide the most accurate data in elastic deuteron-deuteron scattering at intermediate energies. The results can be used to confront upcoming state-of-the-art calculations in the four-nucleon scattering domain, and will, thereby, provide further insights in the dynamics of three- and four-nucleon forces in few-nucleon systems.

description: The Anderson and midgap models are often used in the study of semiconductor heterojunctions, but for van der Waals (vdW) vertical heterostructures they have shown only very limited success. Using the group-IV monochalcogenide vertical heterostructures as a prototypical system, we propose a linear response model and compare the effectiveness of these models in predicting density functional theory (DFT) band alignments, band types and bandgaps. We show that the DFT band alignment is best predicted by the linear response model, which falls in between the Anderson and midgap models. Our proposed model can be characterized by an interface dipole $α\times(E_{m2}-E_{m1})$, where the linear response coefficient $α$ = 0 and 1 corresponds to the Anderson and midgap model respectively, and $E_{m}$ is the midgap energy of the monolayer, which can be viewed as an effective electronegativity. For group-IV monochalcogenides, we show that $α$ = 0.34 best captures the DFT band alignment of the vdW heterostructure, and we discuss the viability of the linear response model considering other effects such as strains and band hybridization, and conclude with an application of the model to predict experimental band alignments.
Common-spectrum process versus cross-correlation for gravitational-wave searches using pulsar timing arrays

description: The North American Nanohertz Observatory for Gravitational Waves (NANOGrav) has recently reported strong statistical evidence for a common-spectrum red-noise process for all pulsars, as seen in their 12.5-yr analysis for an isotropic stochastic gravitational-wave background. However, there is currently very little evidence for quadrupolar spatial correlations across the pulsars in the array, which is needed to make a confident claim of detection of a stochastic background. Here we give a frequentist analysis of a very simple signal+noise model showing that the current lack of evidence for spatial correlations is consistent with the magnitude of the correlation coefficients for pairs of Earth-pulsar baselines in the array, and the fact that pulsar timing arraysbare most-likely operating in the intermediate-signal regime. We derive analytic expressions that allow one to compare the expected values of the signal-to-noise ratios for both the common-spectrum and cross-correlation estimators.

description: We report results of direct measurements of velocity profiles in a microchannel with hydrophobic and hydrophilic walls, using a new high precision method of double-focus spacial fluorescence cross-correlation under a confocal microscope. In the vicinity of both walls the measured velocity profiles do not turn to zero by giving a plateau of constant velocity. This apparent slip is proven to be due to a Taylor dispersion, an augmented by shear diffusion of nanotracers in the direction of flow. Comparing the velocity profiles near the hydrophobic and hydrophilic walls for various conditions shows that there is a true slip length due to hydrophobicity. This length, of the order of several tens of nanometers, is independent on electrolyte concentration and shear rate.

description: While [OIII] narrow-band imaging is commonly used to measure the size of the narrow-line regions (NLRs) in active galactic nuclei (AGNs), it can be contaminated by emission from surrounding starbursts. Recently, we have shown that long-slit spectroscopy provides a valuable alternative approach to probe the size in terms of AGN photoionisation. Moreover, several parameters of the NLR can be directly accessed. We here apply the same methods developed and described for the Seyfert-2 galaxy NGC1386 to study the NLR of five other Seyfert-2 galaxies by using high-sensitivity spatially-resolved optical spectroscopy obtained at the VLT and the NTT. We probe the AGN-photoionisation of the NLR and thus, its ``real'' size using diagnostic line-ratio diagrams.We derive physical properties of the NLR such as reddening, ionisation parameter, electron density, and velocity as a function of distance from the nucleus. For NGC5643, the diagnostic diagrams unveil a similar transition between line ratios falling in the AGN regime and those typical for HII regions as found for NGC1386, thus determining the size of the NLR. For the other four objects, all measured line ratios fall in the AGN regime. In almost all cases, both electron density and ionisation parameter decrease with radius. Deviations from this general behaviour (such as a secondary peak) seen in both the ionisation parameter and electron density can be interpreted as signs of shocks from the interaction of a radio jet and the NLR gas. In several objects, the gaseous velocity distribution is characteristic for rotational motion in an (inclined) emission-line disk in the centre. We compare our results to those of NGC1386 and show that the latter can be considered as prototypical also for this larger sample. We discuss our findings in detail for each object.

description: We ``quantify'' the role of elastic as well as inelastic ggggg pQCD processes in kinetic equilibration within a pQCD inspired parton cascade. The contributions of different processes to kinetic equilibration are manifested by the transport collision rates. We find that in a central Au+Au collision at RHIC energy pQCD Bremstrahlung processes are much more efficient for momentum isotropization compared to elastic scatterings. For the parameters chosen the ratio of their transport collision rates amounts to 5:1.

description: Tsunamis are often generated by a moving sea bottom. This paper deals with the case where the tsunami source is an earthquake. The linearized water-wave equations are solved analytically for various sea bottom motions. Numerical results based on the analytical solutions are shown for the free-surface profiles, the horizontal and vertical velocities as well as the bottom pressure.

description: Cylindrical vector beams (CVBs), which possesses polarization distribution of rotational symmetry on the transverse plane, can be developed in many optical technologies. Conventional methods to generate CVBs contain redundant interferometers or need to switch among diverse elements, thus being inconvenient in applications containing multiple CVBs. Here we provide a passive polarization-selective device to substitute interferometers and simplify generation setup. It is accomplished by reversing topological charges of orbital angular momentum based on polarization-selective Gouy phase. In the process, tunable input light is the only condition to generate CVB with arbitrary topological charges. To cover both azimuthal and radial parameters of CVBs, we express the mapping between scalar Laguerre-Gaussian light on basic Poincaré sphere and CVB on high-order Poincaré sphere. The proposed device simplifies the generation of CVBs enormously, and thus has potentials in integrated devices for both quantum and classic optical experiments.

description: We consider the recently addressed problem of a passive particle (a predator), being the center of a ``sphere of interception'' of radius $R$ and able to absorb other passive particles (the preys) entering into the sphere. Assuming that all the particles are advected by a turbulent flow and that, in particular, the Richardson equation properly describes the relative dispersion, we calculate an analytical expression for the flux into the sphere as a function of time, assuming an initial constant density of preys outside the sphere. In the same framework, we show that the distribution of times of first passage into the sphere has a $t^{-5/2}$ power law tail, seen in contrast to the $t^{-3/2}$ appearing in standard 3D diffusion. We also discuss the correction due to the integral length scale on the results in the stationary case.

description: Cosmic strings were postulated by Kibble in 1976 and, from a theoretical point of view, their existence finds support in modern superstring theories, both in compactification models and in theories with extended additional dimensions. Their eventual discovery would lead to significant advances in both cosmology and fundamental physics. One of the most effective ways to detect cosmic strings is through their lensing signatures which appear to be significantly different from those introduced by standard lenses (id est, compact clumps of matter). In 2003, the discovery of the peculiar object CSL-1 (Sazhin et al.2003) raised the interest of the physics community since its morphology and spectral features strongly argued in favour of it being the first case of gravitational lensing by a cosmic string. In this paper we provide a detailed description of the expected observational effects of a cosmic string and show, by means of simulations, the lensing signatures produced on background galaxies. While high angular resolution images obtained with HST, revealed that CSL-1 is a pair of interacting ellipticals at redshift 0.46, it represents a useful lesson to plan future surveys.

description: Mathematical modeling of cardiac function can provide augmented simulation-based diagnosis tool for complementing and extending human understanding of cardiac diseases which represent the most common cause of worldwide death. As the realistic starting-point for developing an unified meshless approach for total heart modeling, herein we propose an integrative smoothed particle hydrodynamics (SPH) framework for addressing the simulation of the principle aspects of cardiac function, including cardiac electrophysiology, passive mechanical response and electromechanical coupling. To that end, several algorithms, e.g., splitting reaction-by-reaction method combined with quasi-steady-state (QSS) solver , anisotropic SPH-diffusion discretization and total Lagrangian SPH formulation, are introduced and exploited for dealing with the fundamental challenges of developing integrative SPH framework for simulating cardiac function, namely, (i) the correct capturing of the stiff dynamics of the transmembrane potential and the gating variables , (ii) the stable predicting of the large deformations and the strongly anisotropic behavior of the myocardium, and (iii) the proper coupling of electrophysiology and tissue mechanics for electromechanical feedback. A set of numerical examples demonstrate the effectiveness and robustness of the present SPH framework, and render it a potential and powerful alternative that can augment current lines of total cardiac modeling and clinical applications.

description: The application of autonomous mobile robots in robotic security platforms is becoming a promising field of innovation due to their adaptive capability of responding to potential disturbances perceived through a wide range of sensors. Researchers have proposed systems that either focus on utilizing a single mobile robot or a system of cooperative multiple robots. However, very few of the proposed works, particularly in the field of multi-robot systems, are completely dependent on LiDAR sensors for achieving various tasks. This is essential when other sensors on a robot fail to provide peak performance in particular conditions, such as a camera operating in the absence of light. This paper proposes a multi-robot system that is developed using ROS (Robot Operating System) for intruder detection in a single-range-sensor-per-robot scenario with centralized processing of detections from all robots by our central bot MIDNet (Multiple Intruder Detection Network). This work is aimed at providing an autonomous multi-robot security solution for a warehouse in the absence of human personnel.

More Accurate Theory for Bose-Einstein Condensation Fraction

description: In the thermodynamic limit the ratio of system size to thermal de Broglie wavelength tends to infinity and the volume per particle of the system is constant. Our familiar Bose-Einstein statistics is absolutely valid in the thermodynamic limit. For finite thermodynamical system this ratio as well as the number of particles is much greater than 1. However, according to the experimental setup of Bose-Einstein condensation of harmonically trapped Bose gas of alkali atoms this ratio near the condensation temperature($T_c$) typically is $\sim 32$ and at ultralow temperatures well below $T_c$ a large fraction of particles come down to the single particle ground state, and this ratio becomes comparable to 1. We justify the finite size as well as ultralow temperature correction to Bose-Einstein statistics. From this corrected statistics we plot condensation fraction versus temperature graph. This theoretical plot satisfies well with the experimental plot(A. Griesmaier et al..,Phys.Rev.Lett. {\bf{94}}{(2005){160401}}).

description: Σκοπός της διατριβής ήταν η αξιολόγηση των μεταβολών που παρατηρούνται στη σύσταση του παρθένου ελαιολάδου κατά τη χρήση του στο τηγάνισμα τεμαχισμένης πατάτας, ώστε να διαπιστωθεί μετά από πόσες ώρες χρησιμοποίησης σε διαδοχικά τηγανίσματα είναι αναγκαία η αντικατάστασή του, επειδή είναι πια ακατάλληλο σύμφωνα με όσα ισχύουν σε πολλές χώρες. Ένας άλλος σκοπός της παρούσας εργασίας ήταν και η διαπίστωση των συνεπειών που έχει η χρήση του σε διαδοχικά τηγανίσματα στη διατροφική αξία του. Για την παρακολούθηση των μεταβολών των ελαιολάδου, δείγματα ελήφθησαν μετά το τηγάνισμα και πραγματοποιήθηκαν αεριοχρωματογραφική εξέταση στη σύσταση των μεθυλεστέρων των λιπαρών οξέων, προσδιορισμός του αριθμού ανισιδίνης, προσδιορισμός της περιεκτικότητας σε πολικά συστατικά, λήψη και αξιολόγηση των φασμάτων FTIR και προσδιορισμός της ικανότητας δέσμευσης της σταθερής ρίζας 2,2-διφαινυλο-1-πικρυλυδραζυλίου (DPPH).
description: The aim of the present thesis was the evaluation of the changes that were observed to the composition of virgin olive oil during its use to the frying of sliced potato, in order to estimate how many hours of successive frying experiments are required for the oil to be replaced, because it is inappropriate accordingly to the regulations of many countries. Another purpose of this study was to evaluate the consequences of the successive frying to the nutritional value of the olive oil. To monitor the changes to the olive oil, samples were withdrawn after the frying sessions and the gas chromatographic examination of the composition of the fatty acid methyl esters, the determination of the p-anisidine value, the determination of the total polar compounds’ content, the evaluation of FTIR spectra and the evaluation of the radical scavenging ability using the stable radical 2,2-diphenyl-1-picrylhydrazyl (DPPH) were carried out.
