An ecological-systems analysis of anorexia nervosa
Creators: name: Sheppy, Margarette Isabell
Publisher: name: University of British Columbia
Year: 2010

description: Aspects of the ecological systemic approach were used to provide a framework for the understanding of the dynamics of anorexia nervosa and were empirically tested by comparing 30 anorexics and their parents to 34 matched control subjects and their parents. The theoretical model employed was an adaptation of Conger's Ecological-Systems approach which was based on the principles of Bronfenbrennei's theory of human development. The subjects were compared on selected variables arising from the individual, parent, family, and community systems using: 1) the California Psychological Inventory (CPI), 2) the Structural Analysis of Social Behavior (SASB), 3) the Family Environment Scale (FES), and 4) the Pattison Psychosocial Inventory (PPI). Statistical analysis of the difference between means was tested using Hotelling's (T²) procedure followed by a discriminant analysis. The final analysis occured using a Stepwise Discriminant procedure. The results of the stepwise analysis revealed that the Affiliation score (SASB) for the anorexics and the control subjects and the Psychopathic Deviancy score (CPI-Clinical) of the mothers of the anorexics and the controls were the variables which contributed to the discriminant analysis. With the Affiliation and the Psychopathic Deviancy scores alone, it was possible to correctly classify 87.5% of the research subjects. Analyses also showed statistically significant results at the individual, parent, and family levels. Specifically, the anorexic daughters were found to have a negative self-worth as measured by the SASB. They were also more anxious and at odds with themselves and others (CPI). The anorexics were more depressed than the controls, had a greater tendency toward rebelliousness and hostility toward authority, and expressed their feelings in a more indirect manner. The anorexics may use ritualistic thoughts and actions in an attempt to structure their lives to overcome their feelings of losing control. They lack a sense of who they are emotionally and generally feel alienated and lonely as if on the outside looking in. The CPI-Psychopathic Deviancy scale was significantly higher for the mothers of the anorexics than for the controls. No differences were found between the two groups of fathers. Interactions within the family, as perceived by the anorexics, were characterized by overprotection and control by the mothers while the anorexics responded with significantly less affiliation to both their mothers and their fathers. The mothers of the anorexics also viewed their daughters as being less friendly in the relationship. There were no significant findings regarding the perceptions of the fathers of the anorexics and the controls. The families of the anorexics were less supportive, helpful and committed to each other than were the families of the control subjects as measured by the FES.

description: We study the non-monotonic force-extension behaviour of helical ribbons using a new model for inextensible elastic strips. Unlike previous rod models our model predicts hysteresis behaviour for low-pitch ribbons of arbitrary material properties. Associated with it is a first-order transition between two different helical states as observed in experiments with cholesterol ribbons. Numerical solutions show non-uniform uncoiling with hysteresis also occurring under controlled tension. They furthermore reveal a new uncoiling scenario in which a ribbon of very low pitch shears under tension and successively releases a sequence of almost planar loops. Our results may be relevant for nanoscale devices such as force probes.

description: Semiconductor spin qubits may show significant device-to-device variability in the presence of spin-orbit coupling mechanisms. Interface roughness, charge traps, layout or process inhomogeneities indeed shape the real space wave functions, hence the spin properties. It is, therefore, important to understand how reproducible the qubits can be, in order to assess strategies to cope with variability, and to set constraints on the quality of materials and fabrication. Here we model the variability of single qubit properties (Larmor and Rabi frequencies) due to disorder at the Si/SiO$_2$ interface (roughness, charge traps) in metal-oxide-semiconductor devices. We consider both electron qubits (with synthetic spin-orbit coupling fields created by micro-magnets) and hole qubits (with intrinsic spin-orbit coupling). We show that charge traps are much more limiting than interface roughness, and can scatter Rabi frequencies over one order of magnitude. We discuss the implications for the design of spin qubits and for the choice of materials.

description: We present evidence, from Lattice Monte Carlo simulations of the phase diagram of graphene as a function of the Coulomb coupling between quasiparticles, that graphene in vacuum is likely to be an insulator. We find a semimetal-insulator transition at $α_g^\text{crit} = 1.11 \pm 0.06$, where $α_g^{} \simeq 2.16$ in vacuum, and $α_g^{} \simeq 0.79$ on a SiO$_2^{}$ substrate. Our analysis uses the logarithmic derivative of the order parameter, supplemented by an equation of state. The insulating phase disappears above a critical number of four-component fermion flavors $4 < N_f^{\text{crit}} < 6$. Our data are consistent with a second-order transition.

Random multiparty entanglement distillation

description: We describe various results related to the random distillation of multiparty entangled states - that is, conversion of such states into entangled states shared between fewer parties, where those parties are not predetermined. In previous work [Phys. Rev. Lett. 98, 260501 (2007)] we showed that certain output states (namely Einstein-Podolsky-Rosen (EPR) pairs) could be reliably acquired from a prescribed initial multipartite state (namely the W state) via random distillation that could not be reliably created between predetermined parties. Here we provide a more rigorous definition of what constitutes ``advantageous'' random distillation. We show that random distillation is always advantageous for W-class three-qubit states (but only sometimes for Greenberger-Horne-Zeilinger (GHZ)-class states). We show that the general class of multiparty states known as symmetric Dicke states can be readily converted to many other states in the class via random distillation. Finally we show that random distillation is provably not advantageous in the limit of multiple copies of pure states.

Reconstructing Single Field Inflationary Actions From CMBR Data

description: This paper describes a general program for deriving the action of single field inflation models with nonstandard kinetic energy terms using CMBR power spectrum data. This method assumes that an action depends on a set of undetermined functions, each of which is a function of either the inflaton wave function or its time derivative. The scalar, tensor and non-gaussianity of the curvature perturbation spectrum are used to derive a set of reconstruction equations whose solution set can specify up to three of the undetermined functions. The method is then used to find the undetermined functions in various types of actions assuming power law type scalar and tensor spectra. In actions that contain only two unknown functions, the third reconstruction equation implies a consistency relation between the non-gaussianty, sound speed and slow roll parameters. In particular we focus on reconstructing a generalized DBI action with an unknown potential and warp factor. We find that for realistic scalar and tensor spectra, the reconstructed warp factor and potential are very similar to the theoretically derived result. Furthermore, physical consistency of the reconstructed warp factor and potential imposes strict constraints on the scalar and tensor spectral indices.

Long-Term Evolution in Transit Duration of Extrasolar Planets from Magnetic Activity in their Parent Stars
Creators: name: Loeb, Abraham
Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Existing upper limits on variations in the photospheric radius of the Sun during the solar magnetic activity cycle are at a fractional amplitude of 2x10^{-4}. At that level, the transit duration of a close-in planet around a Sun-like star could change by a fraction of a second per year. This magnitude of variation is larger than that caused by other studied effects (owing to proper motion or general-relativistic effects), and should be included in the analysis of constraints on multi-planet systems from transit timing. A temporal correlation between the transit duration and spectroscopic measures of stellar activity can be used to separate the stellar radius change from other effects. The magnetic activity effect could be significantly larger for late-type stars, such as M-dwarfs, which are more variable than the Sun. In general, precision transit measurements provide a new tool for measuring long-term variations of stellar radii.

description: A central question in a large class of strongly correlated electron systems, including heavy fermion compounds and iron pnictides, is the identification of different phases and their origins. It has been shown that the antiferromagnetic (AFM) phase in some heavy fermion compounds is induced by Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction between localized moments, and that the competition between this interaction and Kondo effect is responsible for quantum criticality. However, conclusive experimental evidence of the RKKY interaction in pnictides is lacking. Here, using high resolution $^{23}$Na NMR measurements on lightly Cu-doped metallic single crystals of NaFe$_{1-x}$Cu$_{x}$As ~($x \approx 0.01$) and numerical simulation, we show direct evidence of the RKKY interaction in this pnictide system. Aided by computer simulation, we identify the $^{23}$Na NMR satellite resonances with the RKKY oscillations of spin polarization at Fe sites. Our $^{23}$Na spin-lattice and spin-spin relaxation data exhibits signature of an itinerant and inhomogeneous AFM phase in this system, accompanied by a simulation of Cu-induced perturbation to the ordered moments on the Fe sites. Our NMR results indicate coexistence of local and itinerant magnetism in lightly Cu-doped NaFe$_{1-x}$Cu$_{x}$As.

description: Diamond is a material that offers potential in numerous device applications. In particular, highly boron doped diamond is attractive due to its superconductivity and high Young's Modulus. The fabrication of stable, low resistance, ohmic contacts is essential to ensure proper device function. Previous work has established the efficacy of several methods of forming suitable contacts to diamond at room temperature and above, including carbide forming and carbon soluble metallisation schemes. Herein, the stability of several contact schemes (Ti, Cr, Mo, Ta and Pd) to highly boron doped nanocrystalline diamond was verified down to the cryogenic temperatures with modified Transmission Line Model (TLM) measurements. While all contact schemes remained ohmic, a significant temperature dependency is noted at Tc and at the lowest temperatures the contact resistances ranged from Ti/Pt/Au with ${(8.83 \pm 0.10)\times 10^{-4} \:Ω.cm}$ to Ta/Pt/Au with ${(8.07 \pm 0.62) \times 10^{-6} \:Ω.cm}$.

description: We present a simple and realistic model of supersymmetry breaking. In addition to the minimal supersymmetric standard model, we only introduce a hidden sector gauge group SU(5) and three fields X, F and \bar{F}. Supersymmetry is broken at a local minimum of the potential, and its effects are transmitted to the supersymmetric standard model sector through both standard model gauge loops and local operators suppressed by the cutoff scale, which is taken to be the unification scale. The form of the local operators is controlled by a U(1) symmetry. The generated supersymmetry breaking and mu parameters are comparable in size, and no flavor or CP violating terms arise. The spectrum of the first two generation superparticles is that of minimal gauge mediation with the number of messengers N_mess = 5 and the messenger scale 10^11 GeV < M_mess < 10^13 GeV. The spectrum of the Higgs bosons and third generation superparticles, however, can deviate from it. The lightest supersymmetric particle is the gravitino with a mass of order (1-10) GeV.

description: MAGIS-100 is a next-generation quantum sensor under construction at Fermilab that aims to explore fundamental physics with atom interferometry over a 100-meter baseline. This novel detector will search for ultralight dark matter, test quantum mechanics in new regimes, and serve as a technology pathfinder for future gravitational wave detectors in a previously unexplored frequency band. It combines techniques demonstrated in state-of-the-art 10-meter-scale atom interferometers with the latest technological advances of the world's best atomic clocks. MAGIS-100 will provide a development platform for a future kilometer-scale detector that would be sufficiently sensitive to detect gravitational waves from known sources. Here we present the science case for the MAGIS concept, review the operating principles of the detector, describe the instrument design, and study the detector systematics.

description: We theoretically study a ferrimagnetic domain-wall motion driven by a rotating magnetic field. We find that, depending on the magnitude and the frequency of the rotating field, the dynamics of a ferrimagnetic domain wall can be classified into two regimes. First, when the frequency is lower than a certain critical frequency set by the field magnitude, there is a stationary solution for the domain-wall dynamics, where a domain-wall in-plane magnetization rotates in-phase with the external field. The field-induced precession of the domain wall gives rise to the translational motion of the domain wall via the gyrotropic coupling between the domain-wall angle and position. In this so-called phase-locking regime, a domain-wall velocity increases as the frequency increases. Second, when the frequency exceeds the critical frequency, a domain-wall angle precession is not synchronous with the applied field. In this phase-unlocking regime, a domain wall velocity decreases as the frequency increases. Moreover, the direction of the domain-wall motion is found to be reversed across the angular compensation point where the net spin density of the ferrimagnet changes its sign. Our work suggests that the dynamics of magnetic solitons under time-varying biases may serve as platform to study critical phenomena.

description: The effect of fluctuations on the conductivity of ion channels is investigated. It is shown that modulation of the potential barrier at the selectivity site due to electrostatic amplification of charge fluctuations at the channel mouth exerts a leading-order effect on the channel conductivity. A Brownian dynamical model of ion motion in a channel is derived that takes into account both fluctuations at the channel mouth and vibrational modes of the wall. The charge fluctuations are modeled as a short noise flipping the height of the potential barrier. The wall fluctuations are introduced as a slow vibrational mode of protein motion that modulates ion conductance both stochastically and periodically. The model is used to estimate the contribution of the electrostatic amplification of charge fluctuations to the conductivity of ion channels.

Preparing for counselling : developing and testing an affective awareness training program for the mentally disabled
Creators: name: Sproul, Grace Yuen-Yee Tse
Publisher: name: University of British Columbia
Year: 2010

description: This thesis starts with the observation that if mentally disabled individuals are to establish a place for themselves in the community and successfully cope with the accompanying stress, they must, within their own range of capabilities, (1) learn to recognize their emotions, and (2) learn to express these emotions in socially acceptable ways. The thesis then attempts to explore whether this is a realizable goal. A review of the literature reveals that, in spite of its importance to the mainstreaming process, the emotional development of mentally handicapped individuals has received scant attention toy psychologists, special educators, or counsellors. Some of the reasons for this are explored including an examination of the prevalent "cognitive deterministic" viewpoint which assumes that emotional awareness presupposes higher levels of cognitive development than the mentally handicapped are commonly capable of demonstrating. The thesis notes the recent view of researchers in special education and psychotherapy that appropriate behavioral expression of feelings by the mentally handicapped must develop out of awareness of feelings; it cannot come about through efforts to manipulate manifest behavior alone. Perhaps more importantly, it is argued that affective development takes place in tandem with cognitive abilities, not necessarily as a consequence of them. Based on evidence that affective awareness training for mentally handicapped individuals can and should be pursued along with cognitive and life skills training, the thesis focuses on taking up the challenge of developing and field testing "An Affective Awareness Training Program for the Mentally Disabled." A Gestalt approach to developing awareness of oneself and one's environment was utilized as the theoretical basis for preparing the 46 lessons which make up the content of the "Affective Awareness Training Program." The researcher adapted freely from the work of others to create a unique instructional program designed especially to meet the needs and abilities of Trainable Mentally Retarded (TMR) students. The effectiveness of this program in teaching recognition of, and improving ability to empathize with, expressions of the five primary emotions of joy, sadness, fear, anger, and surprise, was then tested by the researcher using 12 TMR subjects living in an institution (six in the control group, six in the treatment or experimental group). The test instrument for measuring changes in pre-treatment, post-treatment, and retention level performance, was a series of 15 specially prepared video vignettes. Each vignette focused on one emotion and there were three different vignettes portraying each emotion. The thesis concludes that the experimental group, who participated in the affective awareness training program, changed significantly in their ability to recognize and empathize with expressions of the five primary emotions.

description: When a photon collides with a laser pulse, an electron-positron pair can be produced via the nonlinear Breit-Wheeler process. A simulation framework has been developed to calculate this process, which is based on a ponderomotive approach that includes strong-field quantum electrodynamical effects via the locally monochromatic approximation (LMA). Here we compare simulation predictions for a variety of observables, in different physical regimes, with numerical evaluation of exact analytical results from theory. For the case of a focussed laser background, we also compare simulation with a high-energy theory approximation. These comparisons are used to quantify the accuracy of the simulation approach in calculating harmonic structure, which appears in the lightfront momentum and angular spectra of outgoing particles, and the transition from multi-photon to all-order pair creation. Calculation of the total yield of pairs over a range of intensity parameters is also used to assess the accuracy of the locally constant field approximation (LCFA).

description: The magnetic properties of single-domain nanoparticles with different geometric shapes, crystalline anisotropies and lattice structures are investigated. A recently proposed scaling approach is shown to be universal and in agreement with dimensional analysis coupled with an assumption of {\em incomplete} self-similarity. It is used to obtain phase diagrams of magnetic nanoparticles featuring three competing configurations: in-plane and out-of-plane ferromagnetism and vortex formation. The influence of the vortex core on the scaling behavior and phase diagram is analyzed. Three-dimensional phase diagrams are obtained for cylindrical nanorings, depending on their height, outer and inner radius. The triple points in these phase diagrams are shown to be in linear relationship with the inner radius of the ring. Elliptically shaped magnetic nanoparticles are also studied. A new parametrization for double vortex configurations is proposed, and regions in the phase diagram are identified where the double vortex is a stable ground state.

description: An exploratory study was conducted to discover significant events and feelings attached to those events during the experience of unemployment for university graduates under 25 years of age. Twelve university graduates of mixed sex, under the age of 25 were interviewed. The phenomenological/critical incident methodology adapted by Amundson and Borgen (1984) was utilized. The experience was found to be comprised of two segments: the initial holiday period, and the downward trend. Idiosyncratically occurring positive and negative critical incidents were identified. Job search activities were found to be most closely aligned with middle class professionals rather than less educated youth findings. The subjects were found to channel their energy into new areas of interest and activity, particularly further education in spite of feelings of disillusionment. These results may aid counsellors in understanding the experience of unemployed university graduates, and lead to more effective therapeutic interventions for this population.

description: Presidential speeches indicate the government's intentions and justifications supported by a dedicated style and rhetoric oscillating between explanation and controversy. Over a period of sixty years, can we observe stylistic variations by the different French presidents of the Fifth Republic (1958-2018)? Based on official transcripts of all their allocution, this paper illustrates the stylistic evolution and presents the underlying main trends. This study shows that de Gaulle's rhetoric is not mainly dedicated to his own person, or that the two terms of J. Chirac are not fully similar. According to several overall stylistic indicators, Macron's style does not appear as complex compared to his predecessors (F. Hollande or N. Sarkozy) but a more careful analysis clearly demonstrates his noticeable new style. Compared to the recent US presidents, the French ones present some similarities (e.g., similar mean sentence length) and dissimilarities (more I-words, less we-words). In this comparative analysis, Macron's style is also clearly distinctive from both the US and former French presidents. Opting for a more abstract discourse, less anchored in space, using less numbers, E. Macron tends to use long sentences. These various stylistic and rhetorical features could explain his being misunderstood by the French people and his recurrent low approval ratings.

description: Galvanostatic Intermittent Titration Technique (GITT) is widely used to evaluate solid-state diffusion coefficients in electrochemical systems. However, the existing analysis methods for GITT data require numerous assumptions, and the derived diffusion coefficients typically are not independently validated. To investigate the validity of the assumptions and derived diffusion coefficients, we employ a direct pulse fitting method for interpreting GITT data that involves numerically fitting an electrochemical pulse and subsequent relaxation to a one-dimensional, single-particle, electrochemical model coupled with non-ideal transport to directly evaluate diffusion coefficients that are independently verified through cycling predictions. Extracted from GITT measurements of the intercalation regime of FeS2 and used to predict the discharge behavior, our non-ideal diffusion coefficients prove to be two orders of magnitude more accurate than ideal diffusion coefficients extracted using conventional methods. We further extend our model to a polydisperse set of particles to show the validity of a single-particle approach when the modeled radius is proportional to the total volume-to-surface-area ratio of the system.

description: The LIGO/Virgo gravitational--wave observatories have detected 50 BH-BH coalescences. This sample is large enough to have allowed several recent studies to draw conclusions about the branching ratios between isolated binaries versus dense stellar clusters as the origin of double BHs. It has also led to the exciting suggestion that the population is highly likely to contain primordial black holes. Here we demonstrate that such conclusions cannot yet be robust, because of the large current uncertainties in several key aspects of binary stellar evolution. These include the development and survival of a common envelope, the mass and angular momentum loss during binary interactions, mixing in stellar interiors, pair-instability mass loss and supernova outbursts. Using standard tools such as the population synthesis codes StarTrack and COMPAS and the detailed stellar evolution code MESA, we examine as a case study the possible future evolution of Melnick 34, the most massive known binary star system. We show that, despite its well-known orbital architecture, various assumptions regarding stellar and binary physics predict a wide variety of outcomes: from a close BH-BH binary (which would lead to a potentially detectable coalescence), through a wide BH-BH binary (which might be seen in microlensing observations), or a Thorne-Zytkow object, to a complete disruption of both objects by pair-instability supernovae. Thus since the future of massive binaries is inherently uncertain, sound predictions about the properties of BH-BH systems are highly challenging at this time. Consequently, drawing conclusions about the formation channels for the LIGO/Virgo BH-BH merger population is premature.

description: Abstract
Background: Conventional wisdom holds that the microbiological detection of Mycobacterium tuberculosis complex in clinical specimens via culture and phenotypic drug susceptibility testing allows people to be correctly diagnosed and ensures that an effective treatment regimen is selected.
Aim: The objective of this study was to provide a description of the drug resistance profiles of first-line and second-line anti-tuberculous drugs among individuals newly diagnosed with pulmonary tuberculosis in the Addis Ababa metropolitan area, located in Ethiopia.
Methods: A cross-sectional study was conducted between October 2019 and June 2021 on clinically suspected and bacteriologically confirmed pulmonary tuberculosis cases. The GeneXpert MTB/RIF assay was used to detect Mycobacterium tuberculosis complex and resistant to rifampicin. Mycobacterial culture and drug susceptibility testing were performed against 15 anti-tuberculosis drugs using the BD BACTEC™ MGIT™ 960 automated liquid culture system.
Results: A total of 156 Mycobacterium tuberculosis complex isolates were successfully recovered. Males account for 53.8 % [84/156]. Overall, 14.1% [22/156] of isolates were resistant to at least one drug, 85.9 % [134/156] of isolates were pan-susceptible, 7.1% [11/156] of isolates were mono-resistant strains, 5.8% [9/156] of isolates were multidrug-resistant strains, and 3.8% [6/156] of isolates were resistant to all first-line drugs. Interestingly, all isolates were susceptible to all recently recommended second-line drugs tested. Nevertheless, compared to the reference method, the rate of rifampicin resistance detected using GeneXpert MTB/RIF assay had a sensitivity, specificity, and accuracy of 100% [95% CI: 66.4 – 100], 94.6 [95% CI: 89.6 – 97.6], and 94.9 [95% CI: 90.2 – 97.8] respectively, with moderate level of agreement at Cohen kappa value of 0.667.
Conclusion: The rate of MDR-TB in new pulmonary TB cases remained high, at fivefold the national and nearly twofold the global estimated rate in this study. The rate of monoresistance was also high and alarming. The rate of resistance against second-line anti-TB drugs was absent and quite encouraging. The use of GeneXpert MTB/RIF assay alone for the detection of M. tuberculosis introduces 15.7% [34/216] false positivity and 47.1% [8/17] false rifampicin resistance. Treatment initiation with second-line medications without initial drug susceptibility test results may lead to erroneous decisions. [Ethiop. J. Health Dev. 2023; 37(2) 000-000]

description: We investigate radiation hardness within a representative sample of 67 nearby (0.02 $\lesssim $z$ \lesssim$0.06) star-forming (SF) galaxies using the integral field spectroscopic data from the MaNGA survey. The softness parameter $η$ = $\frac{O^{+}/O^{2+}}{S^{+}/S^{2+}}$ is sensitive to the spectral energy distribution of the ionizing radiation. We study $η$ via the observable quantity $η\prime$ (=$\frac{[OII]/[OIII]}{[SII][SIII]}$) We analyse the relation between radiation hardness (traced by $η$ and $η\prime$) and diagnostics sensitive to gas-phase metallicity, electron temperature, density, ionization parameter, effective temperature and age of ionizing populations. It is evident that low metallicity is accompanied by low log $η\prime$, i.e. hard radiation field. No direct relation is found between radiation hardness and other nebular parameters though such relations can not be ruled out. We provide empirical relations between log $\rmη$ and strong emission line ratios N$_2$, O$_3$N$_2$ and Ar$_3$O$_3$ which will allow future studies of radiation hardness in SF galaxies where weak auroral lines are undetected. We compare the variation of [O III]/[O II] and [S III]/[S II] for MaNGA data with SF galaxies and H II regions within spiral galaxies from literature, and find that the similarity and differences between different data set is mainly due to the metallicity. We find that predictions from photoionizaion models considering young and evolved stellar populations as ionizing sources in good agreement with the MaNGA data. This comparison also suggests that hard radiation fields from hot and old low-mass stars within or around SF regions might significantly contribute to the observed $η$ values.

description: The main features of SG-WAS (SkyGlow Wireless Autonomous Sensor), a low-cost device for measuring Night Sky Brightness (NSB), are presented. SG-WAS is based on the TSL237 sensor --like the Unihedron Sky Quality Meter (SQM) or the STARS4ALL Telescope Encoder and Sky Sensor (TESS)--, with wireless communication (LoRa, WiFi, or LTE-M) and solar-powered rechargeable batteries. Field tests have been performed on its autonomy, proving that it can go up to 20 days without direct solar irradiance and remain hibernating after that for at least \mbox{4 months}, returning to operation once re-illuminated. A new approach to the acquisition of average NSB measurements and their instrumental uncertainty (of the order of thousandths of a magnitude) is presented. In addition, the results of a new Sky Integrating Sphere (SIS) method have shown the possibility of performing mass device calibration with uncertainties below 0.02 mag/arcsec$^2$. SG-WAS is the first fully autonomous and wireless low-cost NSB sensor to be used as an independent or networked device in remote locations without any additional infrastructure.
