description: Quality requirements deal with how well a product should perform the intended functionality, such as start-up time and learnability. Researchers argue they are important and at the same time studies indicate there are deficiencies in practice. Our goal is to review the state of evidence for quality requirements. We want to understand the empirical research on quality requirements topics as well as evaluations of quality requirements solutions. We used a hybrid method for our systematic literature review. We defined a start set based on two literature reviews combined with a keyword-based search from selected publication venues. We snowballed based on the start set. We screened 530 papers and included 84 papers in our review. Case study method is the most common (43), followed by surveys (15) and tests (13). We found no replication studies. The two most commonly studied themes are 1) Differentiating characteristics of quality requirements compared to other types of requirements, 2) the importance and prevalence of quality requirements. Quality models, QUPER, and the NFR method are evaluated in several studies, with positive indications. Goal modeling is the only modeling approach evaluated. However, all studies are small scale and long-term costs and impact are not studied. We conclude that more research is needed as empirical research on quality requirements is not increasing at the same rate as software engineering research in general. We see a gap between research and practice. The solutions proposed are usually evaluated in an academic context and surveys on quality requirements in industry indicate unsystematic handling of quality requirements.

description: We demonstrate flux-bias locking and operation of a gradiometric fluxonium artificial atom using two symmetric granular aluminum (grAl) loops to implement the superinductor. The gradiometric fluxonium shows two orders of magnitude suppression of sensitivity to homogeneous magnetic fields, which can be an asset for hybrid quantum systems requiring strong magnetic field biasing. By cooling down the device in an external magnetic field while crossing the metal-to-superconductor transition, the gradiometric fluxonium can be locked either at $0$ or $Φ_0/2$ effective flux bias, corresponding to an even or odd number of trapped fluxons, respectively. At mK temperatures, the fluxon parity prepared during initialization survives to magnetic field bias exceeding $100 \,Φ_0$. However, even for states biased in the vicinity of $1 \,Φ_0$, we observe unexpectedly short fluxon lifetimes of a few hours, which cannot be explained by thermal or quantum phase slips. When operating in a deep-underground cryostat of the Gran Sasso laboratory, the fluxon lifetimes increase to days, indicating that ionizing events activate phase slips in the grAl superinductor.

description: We develop Bayesian statistical methods for discovering and assigning probabilities to non-random (e.g., physical) stellar companions. These companions are either presently bound or were previously bound. The probabilities depend on similarities in corrected proper motion parallel and perpendicular to the brighter component's motion, parallax, and the local phase-space density of field stars. Control experiments are conducted to understand the behavior of false positives. The technique is applied to the Hipparcos Catalogue within 100 pc. This is the first all-sky survey to locate escaped companions still drifting along with each other. In the <100 pc distance range, ~220 high probability companions with separations between 0.01 - 1 pc are found. The first evidence for a population (~300) of companions separated by 1 - 8 pc is found. We find these previously unnoticed naked-eye companions (both with V<6th mag): Capella & 50 Per, delta Vel & HIP 43797, Alioth (epsilon UMa), Megrez (delta UMa) & Alcor (80 UMA), gamma & tau Cen, phi Eri & eta Hor, 62 & 63 Cnc, gamma & tau Per, zeta & delta Hya, beta01, beta02 & beta03 Tuc, N Vel & HIP 47479, HIP 98174 & HIP 97646, 44 & 58 Oph, s Eri & HIP 14913, and pi & rho Cep. High probability fainter companions (V > 6th mag) of primaries with V < 4th mag are found for: Fomalhaut (alpha PsA), gamma UMa, alpha Lib, Alvahet (iota Cephi), delta Ara, beta Ser, iota Peg, beta Pic, kappa Phe and gamma Tuc.

Project Icarus: A Review of Local Interstellar Medium Properties of Relevance for Space Missions to the Nearest Stars

description: I review those properties of the interstellar medium within 15 light-years of the Sun which will be relevant for the planning of future rapid ($v /ge 0.1c$) interstellar space missions to the nearest stars. As the detailed properties of the local interstellar medium (LISM) may only become apparent after interstellar probes have been able to make in situ measurements, the first such probes will have to be designed conservatively with respect to what can be learned about the LISM from the immediate environment of the Solar System. It follows that studies of interstellar vehicles should assume the lowest plausible density when considering braking devices which rely on transferring momentum from the vehicle to the surrounding medium, but the highest plausible densities when considering possible damage caused by impact of the vehicle with interstellar material. Some suggestions for working values of these parameters are provided. This paper is a submission of the Project Icarus Study Group.

description: With an ever evolving cyber domain, delays in reporting incidents are a well-known problem in the cyber insurance industry. Addressing this problem is a requisite to obtaining the true picture of cyber incident rates and to model it appropriately. The proposed algorithm addresses this problem by creating a model of the distribution of reporting delays and using the model to correct reported incident counts to account for the expected proportion of incidents that have occurred but not yet been reported. In particular, this correction shows an increase in the number of cyber events in recent months rather than the decline suggested by reported counts.

description: We consider a mixture of two-component Fermi and (one-component) dipolar Bose gases in which both dipolar interaction and s-wave scattering between fermions of opposite spins are tunable. We show that in the long wavelength limit, the anisotropy in the Fermi-Fermi interaction induced by phonons of the dipolar condensate can strongly enhance the scattering in the triplet channel. We investigate in detail the conditions for achieving optimal critical temperature at which the triplet superfluid begins to compete with the singlet superfluid.

Device for the Field Measurements of Frequency-Dependent Soil Properties in the Frequency Range of Lightning Currents
Creators: name: Kuklin, Dmitry

Year: 2022
Subjects: subject: Geophysics (physics.geo-ph)
subject: FOS: Physical sciences

description: Existing approaches for the field measurements of the frequency-dependent soil properties take a significant amount of time, making it difficult to obtain new experimental data and study the electrical soil properties further. However, a relatively uncomplicated measurement device assembled from accessible electronic components can make the measurements almost as easy as those for the regular low-frequency resistivity. The article presents a detailed description of such a device: the description includes the functional scheme, pseudocodes for central parts of the calculation algorithm, used electronic components, and working principle of the device. The article discusses the reasons behind the chosen parameters of the device (such as isolation between the measurement circuits, generated signal waveform, usage of the electrode arrays) and addresses other possible approaches for the measurements. The paper also provides several measurement results and a comparison with a calculation result for a particular electrode array configuration. Finally, the work describes essential aspects affecting the accuracy of measurement results.
Spin-orbit coupling and anisotropic exchange in two-electron double quantum dots

description: The influence of the spin-orbit interactions on the energy spectrum of two-electron laterally coupled quantum dots is investigated. The effective Hamiltonian for a spin qubit pair proposed in F. Baruffa et al., Phys. Rev. Lett. 104, 126401 (2010) is confronted with exact numerical results in single and double quantum dots in zero and finite magnetic field. The anisotropic exchange Hamiltonian is found quantitatively reliable in double dots in general. There are two findings of particular practical importance: i) The model stays valid even for maximal possible interdot coupling (a single dot), due to the absence of a coupling to the nearest excited level, a fact following from the dot symmetry. ii) In a weak coupling regime, the Heitler-London approximation gives quantitatively correct anisotropic exchange parameters even in a finite magnetic field, although this method is known to fail for the isotropic exchange. The small discrepancy between the analytical model (which employes the linear Dresselhaus and Bychkov-Rashba spin-orbit terms) and the numerical data for GaAs quantum dots is found to be mostly due to the cubic Dresselhaus term.

description: We introduce a family of models, which we name matrix models associated with children's drawings -- the so-called dessin d'enfant. Dessins d'enfant are graphs of a special kind drawn on a closed connected orientable surface (in the sky). The vertices of such a graph are small disks that we call stars. We attach random matrices to the edges of the graph and get multimatrix models. Additionally, to the stars we attach source matrices. They play the role of free parameters or model coupling constants. The answers for our integrals are expressed through quantities that we call the "spectrum of stars." The answers may also include some combinatorial numbers, such as Hurwitz numbers or characters from group representation theory.

description: We propose a simple scenario which explains why our Universe appears spatially flat, homogeneous and isotropic. We use the Einstein-Cartan-Kibble-Sciama (ECKS) theory of gravity which naturally extends general relativity to include the spin of matter. The torsion of spacetime generates gravitational repulsion in the early Universe filled with quarks and leptons, preventing the cosmological singularity: the Universe expands from a state of minimum but finite radius. We show that the dynamics of the closed Universe immediately after this state naturally solves the flatness and horizon problems in cosmology because of an extremely small and negative torsion density parameter, $Ω_S \approx -10^{-69}$. Thus the ECKS gravity provides a compelling alternative to speculative mechanisms of standard cosmic inflation. This scenario also suggests that the contraction of our Universe preceding the bounce at the minimum radius may correspond to the dynamics of matter inside a collapsing black hole existing in another universe, which could explain the origin of the Big Bang.

Accretion

description: The accretion of material from the protoplanetary disk onto the star is essential in the formation of Sun-like stars and in setting the properties of the disk at the time when planet formation happens. Although often described by simple and static models, the accretion process is inherently variable. For this reason, variability of young stars is perhaps the most important source of information on the accretion process and on the behavior of the innermost region of the systems. We designed a program to study six young stars in the Chamaeleon I star-forming region with the aim of characterizing the accretion process in time, to study the accretion diagnostic parameters and to examine the innermost part of the circumstellar disk. We combined the high-precision optical photometric observations of the TESS space telescope with contemporaneous ground-based IJHK-band photometry, and multi-epoch high-resolution optical spectroscopic observations obtained by the VLT/ESPRESSO and the 2.2m /FEROS spectrographs. Besides uncovering the periodic light variations that can be attributed to the stellar rotation, the uninterrupted TESS observations allowed us to examine the shorter timescale fluctuations due to accretion variability and also revealed flare-like events in the light curves. Our high-resolution spectroscopy allowed us to examine the amplitude, timescale and pattern of variability in accretion tracers which carry information on the distribution and the kinematics of the accreting material, the density structure of the inner disk, stellar activity, and the presence of outflows or jets. Where we have contemporaneous photometry and spectroscopy we linked the photometric variability to spectroscopic variations.

Instrumentation and fabrication techniques for semiconductor-based quantum technologies

description: Large-scale quantum computers have the potential to perform calculations that are otherwise impossible, a capability that could power exciting advances in fields such as materials design and optimization. Building large-scale quantum computers with spin qubits is appealing because they have long coherence times and can be fabricated on silicon chips using an industrial process amenable to scaling. State-of-the-art spin qubit systems are still small, having only just reached the 2-qubit and 4-qubit scale, and their performance and scalability are not optimized yet. Connecting large numbers of spin qubits on chips remains a challenge. In this thesis we demonstrate a simplified fabrication process using a single layer of gates to realize hole spin qubits, anticipated to be easier to scale up than conventional approaches, based on quantum dots formed in a germanium quantum wells on silicon substrates. We also devised a novel approach to reduce contact resistance to the quantum well. Using this process we successfully built quantum dots, as evidenced by Coulomb blockade spectroscopy. Future work will demonstrate quantum bits using this process. Optimization of qubits based on quantum devices requires cooling them down below 4 Kelvin and connecting them to microwave control and measurement circuits. Designing a high frequency control and measurement apparatus is challenging since it requires suppression of stray resonances and crosstalk in the setup. Typically each research group designs its own apparatus, or purchases an expensive apparatus that is not possible to customize. In this thesis, we design and test an apparatus for controlling and measuring few-qubit devices using low-frequency and microwave electrical signals, that can be used to optimize qubit devices. Our setup has -40 dB cross-talk with no resonances up to 7 GHz, and has the advantage of being small in size (< 44 mm diameter) so it fits within the bore of a small electromagnet or cryostat. We share our apparatus and design freely with the research community, enabling new groups to more quickly build and customize an apparatus to test their chips. These results will help the quantum computing research community to fabricate and test advanced quantum computing devices faster.

description: We study the concentration of dark matter halos and its evolution in N-body simulations of the standard LCDM cosmology. The results presented in this paper are based on 4 large N-body simulations with about 10 billion particles each: the Millennium-I and II, Bolshoi, and MultiDark simulations. The MultiDark (or BigBolshoi) simulation is introduced in this paper. This suite of simulations with high mass resolution over a large volume allows us to compute with unprecedented accuracy the concentration over a large range of scales (about six orders of magnitude in mass), which constitutes the state-of-the-art of our current knowledge on this basic property of dark matter halos in the LCDM cosmology. We find that there is consistency among the different simulation data sets. We confirm a novel feature for halo concentrations at high redshifts: a flattening and upturn with increasing mass. The concentration c(M,z) as a function of mass and the redshift and for different cosmological parameters shows a remarkably complex pattern. However, when expressed in terms of the linear rms fluctuation of the density field sigma(M,z), the halo concentration c(sigma) shows a nearly-universal simple U-shaped behaviour with a minimum at a well defined scale at sigma=0.71. Yet, some small dependences with redshift and cosmology still remain. At the high-mass end (sigma < 1) the median halo kinematic profiles show large signatures of infall and highly radial orbits. This c-sigma(M,z) relation can be accurately parametrized and provides an analytical model for the dependence of concentration on halo mass. When applied to galaxy clusters, our estimates of concentrations are substantially larger -- by a factor up to 1.5 -- than previous results from smaller simulations, and are in much better agreement with results of observations.

Red and near-infrared luminescent materials for biological imaging
Creators: name: Paisley, Nathan R.
Publisher: name: University of British Columbia
Year: 2022

description: Fluorescence imaging is a critical tool for visualizing cellular structures and complex biological processes; however, background autofluorescence from molecules and structures within the cell can severely reduce the signal-to-noise ratio (SNR) and imaging quality. Time-resolved imaging (TRI) and two-photon excited fluorescence (2PEF) microscopy are two techniques that can be used to remove background autofluorescence and improve SNR. Imaging probes with long lifetime emission are required to utilize TRI techniques. Purely organic materials with properties such as thermally activated delayed fluorescence (TADF) exhibit long lifetime photoluminescence. Additionally, to image living samples, luminescent imaging probes should ideally absorb and emit within the biological transparency window (650–1350 nm), but efficient TADF emission within this range is rare. Work described in this thesis uses materials exhibiting TADF or 2PEF to develop biological imaging probes with emission within the biological transparency window. These materials were synthesized as small molecules or polymerized with a semiconductor host and formed into polymer nanoparticles called polymer dots (Pdots) that retain the photophysical properties required for TRI or 2PEF microscopy. New deep-red/near-infrared (NIR) emissive TADF monomers were synthesized and the mechanism behind TADF was explored using density functional theory (DFT). Pdots with a cell-penetrating peptide mimic shell were demonstrated to efficiently enter multiple cell lines in under 30 minutes while retaining high cell viability. Proof-of-concept experiments for the use of these Pdots in TRI demonstrated that the TADF emission can be separated from background fluorescence. This work represents some of the first demonstrations of Pdots containing red to NIR emissive TADF polymers for cellular imaging. For materials exhibiting 2PEF, it was shown that the electron donor moieties effect on planarity directly correlates to the relative strength of 2PEF within a series. Additionally, in the closely related field of semiconductor polymers, reactive semifluorinated polymers were investigated for the efficient synthesis of a series of polymers based on p-type and n-type semiconductor motifs commonly found in organic light-emitting diodes (OLEDs), organic thin-film transistors (OTFTs), and organic photovoltaics (OPVs). Experiments demonstrating that semifluorinated polymers can provide a useful building block in the synthesis of organic electronic materials were conducted.

description: The Hamilton action principle, also known as the principle of least action, and Lagrange equations are an integral part of advanced undergraduate mechanics. At present, substantial efforts are ongoing to suitably incorporate the action principle in introductory physics courses. Although the Hamilton principle is oft stated as "the action for any nearby trial world-line is greater than the action for the classical world-line", the landscape of action in the space of world-lines is rarely explored. Here, for three common problems in introductory physics - a free particle, a uniformly accelerating particle, and a simple harmonic oscillator - we present families of trial world-lines, characterized by a few parameters, that evolve continuously from their respective classical world-lines. With explicit analytical expressions available for the action, they permit a graphical visualization of the action landscape in the space of nearby world-lines. Although these trial world-lines form only a subset of the space of all nearby world-lines, they provide a pedagogical tool that complements the traditional Lagrange equation approach and is well-suited for advanced undergraduate students.

description: In dieser Bachelorarbeit wird das Problem der Auswahl von Antennenstandorten für eine maximale räumliche Abdeckung in 5G-Funknetzen untersucht. Das Hauptziel besteht darin, eine effiziente Lösung für dieses kombinatorische Optimierungsproblem zu finden, indem es als Partial Set Covering Problem formuliert und gelöst wird. Die Arbeit gliedert sich in zwei Teile: Der erste Teil bietet eine Einführung in die mathematischen Grundlagen des Partial Set Covering Problems, einschließlich Definitionen, Formulierung und Lösungsverfahren. Im zweiten Teil wird ein praktischer Ansatz zur Lösung dieses Problems präsentiert, wobei realen Instanzen für die Auswahl von Antennenstandorten analysiert werden. Hierbei werden zwei Hauptfragen untersucht: 1) Wie kann die gegebene Instanz in ein Partial Set Covering Problem umformuliert werden? 2) Wie kann dieses Problem mithilfe eines heuristischen Verfahrens, insbesondere des Simulated-Annealing-Algorithmus, gelöst werden? Die Ergebnisse dieser Arbeit tragen dazu bei, fundierte Entscheidungen über den Aufbau von 5G-Netzen zu treffen und die Netzwerkabdeckung unter Berücksichtigung von Nebenbedingungen zu maximieren.

Stimuli-responsive DNA-based hydrogels for controlled drug delivery applications
Publisher: name: UW URMSE
Year: 2021

Adverse side effects from drugs being delivered to healthy tissue inside the body remain a persistent challenge within the medical field. Targeted drug delivery by use of stimuli-responsive DNA-based hydrogels emerge as a promising solution to this issue. These hydrogels can be used for a "smart" controlled drug delivery system that enables a drug to be delivered to a target location in a controlled amount by responding to an external stimulus. DNA hydrogels that respond to various non-biological and biological stimuli and their potential applications for targeted drug delivery are discussed in this paper.

description: Injection of material from a core-collapse supernova into the solar system's already-formed disk is one proposed mechanism for producing the short-lived radionuclides, such as 26Al and 41Ca, inferred from isotopic studies of meteorites to have existed in the solar nebula. This hypothesis has recently been challenged on the basis that the injection of enough supernova material to match the meteoritic abundances of 26Al and 41Ca would produce large, measureable, and unobserved collateral effects on oxygen isotopes. Here we calculate again the shifts in oxygen isotopes due to injection of supernova material in the solar nebula, using a variety of nucleosynthetic conditions of our own progenitor explosions. Unlike previous studies of this type, we also consider the effect of non-homogeneity in abundance distribution of the nucleosynthesis products after the explosion. We calculate the shifts in oxygen isotopes due to injection of sufficient supernova material to produce the meteoritic abundances of 26Al and 41Ca, and analyze the predicted shifts in detail for compatibility with meteoritic data. We find that the range in possible isotopic shifts is considerable and sensitive to parameters such as progenitor mass and anisotropy of the explosion; however, a small number of compatible scenarios do exist. Because of the wide range of outcomes and the sensitivity of isotopic yields to assumed conditions, it is difficult to constrain the supernova that may have led to injection of 26Al in the solar nebula. Conversely, we argue that the existence of viable counterexamples demonstrates that it is premature to use oxygen isotopes to rule out injection of 26Al and 41Ca into the solar nebula protoplanetary disk by a nearby supernova.

description: We report on the feasibility of the direct measurement of the top Yukawa coupling g_t at the International Linear Collider (ILC) during its first phase of operation with a center-of-mass energy of 500 GeV. The signal and background models incorporate the non-relativistic QCD corrections which enhance the production cross section near the t-tbar threshold. The e+e- -> t tbar H signal is reconstructed in the 6-jet + lepton and the 8-jet modes. The results from the two channels are combined. The background processes considered are e+e- -> t bbar W- / tbar b W+ (which includes e+e- -> t tbar), e+e- -> t tbar Z, and e+e- -> t tbar g* -> t tbar b bar. We use a realistic fast Monte-Carlo detector simulation. Signal events are selected using event shape variables, through jet clustering, and by identifying heavy flavor jets. Assuming a Higgs mass of 120 GeV, polarized electron and positron beams with (Pe-,Pe+) = (-0.8,+0.3), and an integrated luminosity of 1 ab-1, we estimate that the e+e- -> t tbar H events can be seen with a statistical significance of 5.2 sigma, corresponding to the relative top Yukawa coupling measurement accuracy of |Delta g_t / g_t| = 10%.

Progress in top-down production of graphene
Publisher: name: UW URMSE
Year: 2021

In this review, the focus is on recent studies into production methods of graphene classified as "top-down". The methods are electrochemical exfoliation, liquid phase exfoliation (LPE), and liquid-phase pulsed laser ablation (LP-PLA). Each method is introduced and discussed based on changes that can be made to the chemistry involved, the layout and tools of the method, or additional steps taken. As graphene is looked at increasingly for research purpose, it is important to optimize its processing and gain a better understanding of each. TEM and SEM imagery help to give an indication of the structure, quality and morphology of graphene product made.

Organic piezoelectric wearable and implantable sensors
Publisher: name: UW URMSE
Year: 2021

Piezoelectric properties, capable of transforming mechanical stress into an electrical potential, or vice versa, are currently being explored for wearable and implantable sensor applications. The historical focus of studies has centered around inorganic materials systems. However, attention has recently shifted to organic piezoelectric materials, with an interest in the biocompatible and biodegradable properties for biomedical applications. The applications hold promise as a more sustainable and ideal alternative to the current industry-standard sensors. This paper explores the current understanding of organic piezoelectric materials, ongoing research into biomedical applications in sensor technology, and specific examples of current sensor prototypes.
Investigating the aging of release coating in aerospace composites manufacturing
Publisher: name: UW URMSE
Year: 2021

During aerospace composites manufacturing, release coating is applied on tools to minimize adhesive bonding and facilitate the removal of cured parts. For prepreg manufacturing, the aerospace industry typically uses semi-permanent release coatings that require frequent reapplications to mitigate aging effects. Release coatings are often over- or under-applied due to a lack of knowledge regarding the relationship between aging and processing. Understanding the relationship between aging and processing is critical to ensure end-part quality. This paper presents the investigation of aging in release coating using FTIR. The FTIR absorbance peak intensities of functional groups in release coating are shown to be valuable for qualitative evaluation of aging.
