description: Facilitating the use and exchange of biological samples and associated health data in large cross-border collaborations is essential to promoting biomedical research. However, practices for the ethical review of research projects are not harmonized across European countries and there are no systems for mutual recognition of ethical approval decisions (RECognition). Variations in legal frameworks provide an additional level of complexity to this landscape. Thus shared information on Research Ethics Committee (REC) requirements in different EU countries is a critical element for a harmonized and collaborative environment. It leads to a need for an updated mapping of ethics review processes for biobank-based research at European level. To promote a framework of mutual RECgnition, it is key to understand the common needs and challenges and the national level REC workflows, needs and requirements. The Task Force REC, as a part of the ELSI Services of BBMRI-ERIC dedicated to RECs͛ needs and issues, has launched a pilot survey targeting nine EEA Countries (Austria, Czech Republic, Germany, Greece, Italy, Latvia, Malta, Norway, United Kingdom) as the first step of an extensive European REC mapping of practices and legal landscapes for ethical approval.

description: We consider the elastic deformation of a circular cylindrical sector composed of an incompressible isotropic soft solid when it is straightened into a rectangular block. In this process, the circumferential line elements on the original inner face of the sector are stretched while those on the original outer face are contracted. We investigate the geometrical and physical conditions under which the latter line elements can be contracted to the point where a localized incremental instability develops. We provide a robust algorithm to solve the corresponding two-point boundary value problem, which is stiff numerically. We illustrate the results with full incremental displacement fields in the case of Mooney-Rivlin materials and also perform an asymptotic analysis for thin sectors
The practice of informal waste recovery and solid waste management in Kathmandu, Nepal
Creators: name: Yoshida, Yukiko
Publisher: name: University of British Columbia
Year: 2009

description: The issue of Solid Waste Management (SWM) has become a major urban problem in developing countries. SWM is a basic service function which requires sizable injections of national and international assistance. Nevertheless, the results of investments are often far from satisfactory: large amounts of garbage remain uncollected, resulting in serious environmental pollution. In most developing countries, two SWM systems exist side-by-side. One is a "formal system", which is managed by public institutions or registered corporations. It is associated with registered ownership, organized labour, capital investment and modern technology. The main activities of the formal sector are typically based on collection, transportation and disposal of waste. The other, "informal system", is based on waste recovery activities operating outside the official, legal, and institutional framework. It is associated with unregistered ownership, small scale operation, low capital and labour intensive inputs, and local technology. The purpose of this paper is to analyse the linkages between formal SWM and informal waste recovery practises in Kathmandu, Nepal. Methods of investigation included interviews of actors involved in both formal and informal SWM systems and site observation. Through this investigation, the pathways of solid waste recovery of Kathmandu were identified. It was found that a highly organized informal sector recovers significant amounts of waste from the municipal solid waste stream. Different actors in the informal sector play different roles in a rigid hierarchical social system. Informal waste recovery as a whole not only provides a source of income to one of the poorest segments of the population, but it also lessens the need for a costly, sophisticated SWM system. Based on the findings of the study, the thesis concludes that informal waste recovery activities hold potential that is presently inhibited and handicapped in many ways. One of the major causes of such limitations is the lack of a source separation mechanism in the current SWM system. It is recommended that Kathmandu's waste management handling agencies recognize the importance of informal recovery practices and encourage source separation to enhance the quality of the city's overall solid waste management system.
The effect of NLO conformal spins in azimuthal angle decorrelation of jet pairs

description: Azimuthal angle decorrelation in inclusive dijet cross sections is studied analytically to take into account the next-to-leading corrections to the BFKL kernel while keeping the jet vertices at leading order. The spectral representation on the basis of leading order eigenfunctions is generalized to include the dependence on conformal spins. With this procedure running coupling effects and angular dependences are both included. It is shown how the angular decorrelation for jets with a wide relative separation in rapidity largely decreases at this higher order in the resummation.

By varying a single experimental parameter we can coherently move from a fully separable state to a maximally robust W state, while at all times preserving an optimally robust, symmetric entanglement configuration. We achieve a high fidelity with these configurations experimentally, including the highest reported W state fidelity.

description: Let $K$ be a number field. Given a polynomial $f(x)\in K[x]$ of degree $d\ge 2$, it is conjectured that the number of preperiodic points of $f$ is bounded by a uniform bound that depends only on $d$ and $[K:\mathbb Q]$. However, the only examples of parametric families of polynomials with no preperiodic points are known when $d$ is divisible by either $2$ or $3$ and $K=\mathbb Q$. In this article, given any integer $d\ge 2$, we display infinitely many parametric families of polynomials of the form $f_t(x)=x^d+c(t)$, $c(t)\in K(t)$, with no rational preperiodic points for any $t\in K$.

Hellas Eschate : the interactions of Greek and non-Greek populations in Bactria-Sogdiana during the Hellenistic period
Creators: name: Jassar, Gurtej
Publisher: name: University of British Columbia
Year: 2009

description: This study deals with the syncretism between Greek and non-Greek peoples as evidenced by their architectural, artistic, literary and epigraphic remains. The sites under investigation were in the eastern part of the Greek world, particularly Ai Khanoum, Takht-i-Sangin, Dilberdjin, and Kandahar. The reason behind syncretism was discussed in the introduction, which included the persistence of the ancient traditions in Egypt, Mesopotamia, and Bactria even after being conquered by the Greeks. The Greeks highly respected these ancient 'repositories of wisdom', and the fluidity and adaptability of Greek culture was not particularly restrictive to foreign elements. Religious freedom and the identification of Greek gods with the local gods by the Greeks appears to have been a primary impetus in some aspects of syncretism, while functionality appears to have been important in the architectural adaptations to the climatic and environmental conditions of Bactria. It was ultimately found that Greek/non-Greek interactions in Bactria- Sogdiana were more complex than originally thought. Syncretism occurred in many cultural and biological aspects, in more than the simple Greek/non- Greek manner. The various non-Greek cultures (viz. Achaemenids, Scythians, Indians, and neo-Babylonians) also had interactions with each other. There was also a coexistence of the various cultures and peoples. Further evidence can only come from renewed excavations in Afghanistan.

description: Food rescue has emerged as a promising approach to address the interrelated issues of food insecurity and food waste. According to the food waste hierarchy, the next best strategy after food waste prevention is to donate surplus food for human consumption. However, while some countries have well-established networks of charities and government support to promote surplus food donation and food rescue in most developing countries is often less structured and smaller in scale. To gain insights into the current landscape of food rescue, this study thoroughly examined existing food rescue operations and systems, mainly from the UK, Singapore, Malaysia, India, and the Philippines. The study also analysed several countries' food rescue policy environments to understand how an enabling environment can be created. A particular focus was set on food safety being a critical consideration when rescuing and donating surplus food. Simplified food safety guidelines, staff training, and adequate storage and transportation facilities are crucial to food safety. Effective partnerships between food rescue organizations, food businesses, government agencies, and other stakeholders are also critical to the success of food rescue efforts. The study found a need to develop such partnerships in developing countries, where they may be less established than in the Global North. To facilitate the development of an enabling environment for food rescue in low- and middle-income countries (LMICs), the study developed a set of templates, including relevant food safety guidelines, partnership contracts, and policy templates. These resources can serve as valuable tools for stakeholders in LMICs to promote and enhance food rescue efforts that can help address food insecurity and reduce food waste.

Ideal intersections for radio-frequency trap networks

description: We investigate the possible form of ideal intersections for two-dimensional rf trap networks suitable for quantum information processing with trapped ions. We show that the lowest order multipole component of the rf field that can contribute to an ideal intersection is a hexapole term uniquely determined by the tangents of the intersecting paths. The corresponding ponderomotive potential does not provide any confinement perpendicular to the paths if these intersect at right angles, indicating that ideal right-angle X intersections are impossible to achieve with hexapole fields. Based on this result, we propose an implementation of an ideal oblique-X intersection using a three-dimensional electrode structure.

description: Committor analysis is a powerful, but computationally expensive, tool to study reaction mechanisms in complex systems.
 The committor can also be used to generate initial trajectories for transition path sampling, a less-expensive technique
 to study reaction mechanisms. The main goal of the project was to facilitate an implementation of committor analysis
 in the software application OpenPathSampling (http://openpathsampling.org/) that is performance portable across a
 range of HPC hardware and hosting sites. We do this by the use of hardware-enabled MD engines in OpenPathSampling
 coupled with a custom library extension to the data analytics framework Dask (https://dask.org/) that allows for the
 execution of MPI-enabled tasks in a steerable High Throughput Computing workflow. The software developed here is being used to generate initial trajectories to study a conformational change in the main protease of the SARS-CoV-2 virus, which causes COVID-19. This conformational change may regulate the accessibility of the active site of the main protease, and a better understanding of its mechanism could aid drug design.

According to the LLM prescription, half BPS excitations of AdS_5 x S^5 geometries in type IIB string theory can be mapped into free fermion configurations. We show that unitarity of the theory describing these fermions is intimately related to the protection of the chronology in the dual geometries.

They are derived from the off-shell Compton scattering amplitude $\mathcal{W}_{μν}(a,p,q)$ of massless quarks with momentum $p$. The Wilson coefficients are classified according to the transformation of the corresponding operators under the hypercubic group H(4). We give selected examples for a special choice of the momentum transfer $q$. All Wilson coefficients are given in closed analytic form and in an expansion in powers of $a$ up to first corrections.

description: Textual explanations have proved to help improve user satisfaction on machine-made recommendations. However, current mainstream solutions loosely connect the learning of explanation with the learning of recommendation: for example, they are often separately modeled as rating prediction and content generation tasks. In this work, we propose to strengthen their connection by enforcing the idea of sentiment alignment between a recommendation and its corresponding explanation. At training time, the two learning tasks are joined by a latent sentiment vector, which is encoded by the recommendation module and used to make word choices for explanation generation. At both training and inference time, the explanation module is required to generate explanation text that matches sentiment predicted by the recommendation module. Extensive experiments demonstrate our solution outperforms a rich set of baselines in both recommendation and explanation tasks, especially on the improved quality of its generated explanations. More importantly, our user studies confirm our generated explanations help users better recognize the differences between recommended items and understand why an item is recommended.

description: Late blight caused by Phytophthora infestans is the most destructive disease of potatoes worldwide and is most notable as the cause of the Irish potato famine of the mid 1840’s. Whole mitochondrial genome sequences were generated from 44 Australian, two UK and one US isolates of P. infestans stored as either herbarium specimens or as recent samples on FTA cards, spanning the period 1873–2019. Mitochondrial (mt) genome sequence comparison confirmed that over the past c. 110 years, an old A1 strain of P. infestans has been present in Australia. There was evidence, however, that P. infestans had been introduced on multiple separate occasions in the early 1900s prior to the introduction of quarantine measures. The 44 Australian samples included six infected specimens of the Australian native kangaroo apple (Solanum aviculare) collected in 1911. The P. infestans mt genome sequences from these isolates clustered with P. infestans from infected potatoes collected in Victoria (1910, 1911, 1986, 1989), South Australia (1909, 2003) and Tasmania (1910, 2019), supporting the hypothesis that Australia has one old strain that has survived since the first arrival of the pathogen into the country. The study highlights the success of Australia’s potato biosecurity setting and supports the need for ongoing surveillance and biosecurity measures to prevent the introduction of the newer more aggressive strains of the pathogen.

This can be used to perform quantum computations [A. Yu. Kitaev, Ann. Phys. (N.Y.) 303, 2 (2003)]. We show how to simulate the creation and manipulation of Abelian and non- Abelian anyons in topological lattice models using trapped atoms in optical lattices. Our proposal, feasible with present technology, requires an ancilla particle which can undergo single-particle gates, be moved close to each constituent of the lattice and undergo a simple quantum gate, and be detected.

Results indicate that soybean oil futures should in fact be part of a composite hedge, and that in some instances greater hedging weight should be placed on the soybean oil futures contract than the conventionally used heating oil futures contract.
Robust observer for uncertain linear quantum systems

description: In the theory of quantum dynamical filtering, one of the biggest issues is that the underlying system dynamics represented by a quantum stochastic differential equation must be known exactly in order that the corresponding filter provides an optimal performance; however, this assumption is generally unrealistic. Therefore, in this paper, we consider a class of linear quantum systems subjected to time-varying norm-bounded parametric uncertainties and then propose a robust observer such that the variance of the estimation error is guaranteed to be within a certain bound. Although in the linear case much of classical control theory can be applied to quantum systems, the quantum robust observer obtained in this paper does not have a classical analogue due to the system's specific structure with respect to the uncertainties. Moreover, by considering a typical quantum control problem, we show that the proposed robust observer is fairly robust against a parametric uncertainty of the system even when the other estimators--the optimal Kalman filter and risk-sensitive observer--fail in the estimation.

description: From the 1800s onwards, sitar makers and affiliated artisans have shaped transnational cultural, political, and material exchanges of sitar making and music through their labors and roles as economic and cultural agents. However, historical representations that perpetuate Western European and Indian social, labor, and economic theories decontextualize, pathologize, and portray sitar making—alongside other forms of Indian hereditary artisanship—as incompatible with modern economic systems. Representing sitar makers as anachronistic intensifies their political and socioeconomic precarities as largely invisible artisans whose labors sustain vibrant worlds of sitar music in and beyond India. In this dissertation, I argue that five intersecting domains of discourse and practice render invisible sitar-making labors in transnational settings: 1) Indian and Western European social and economic theories of Indian hereditary artisanship; 2) colonial-era portraiture and museum curation of sitars and hereditary Indian artisans; 3) the opposition of constructs of labor and craft in sitar makers’ self-representation and literature on Indian artisanship; 4) leisure musical consumption in diasporic settings; and 5) Indian political policies on handicraft. I uncover connections between these five domains through historiographic and ethnographic research in museums, archives, and with sitar makers in India and the United States. Case studies from this research uncover sitar-making artisans’ roles as dynamic sociopolitical and cultural agents who adapt to and harness changing economic, political, and virtual infrastructures. Theoretically speaking, I draw upon interdisciplinary perspectives from critical organology, South Asian studies, economic and labor theory, and material culture studies to reveal how sitar makers navigate unpredictable material, political, social, and economic conditions. This historically grounded perspective counters contemporary cultural representations that erase or underplay the role of sitar makers in shaping the proliferation and cultural exchange of Hindustani music in India and its diasporas. It also reasserts the importance of historical, sociopolitical, and economic contexts in applications of material culture and ethnomusicological studies. By tracing how sitar makers engage, resist, leverage, and subvert historical processes and narratives through exercising their sociopolitical agencies, this dissertation establishes sitar makers’ roles as instrumental agents of musical and artisanal production.
Unexpected thermo-elastic effects in liquid glycerol by mechanical deformation

description: It is commonly accepted that shear waves do not propagate in a liquid medium. The shear wave energy is supposed to dissipate nearly instantaneously. This statement originates from the difficulty to access static shear stress in macroscopic liquids. In this paper, we take a different approach. We focus on the stability of the thermal equilibrium while the liquid (glycerol) is submitted to a sudden shear strain at sub-millimetre scale. A thermal response of the deformed liquid is unveiled. The liquid exhibits simultaneous and opposite bands of about +0.04 °C and -0.04 °C temperature variations. The sudden thermal changes exclude the possibility of heat transfer and highlight the ability of the liquid to store the shear energy in non-uniform thermodynamic states. The thermal effects depend nearly linearly on the amplitude of the deformation supporting the hypothesis of a shear wave propagation (elastic correlations) extending up to several hundreds microns. This new physical effect can be explained in terms of the underlying phonon physics of confined liquids, which unveils a hidden solid-like response with many similarities to glassy systems.
Torsion instability of soft solid cylinders

Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: The application of pure torsion to a long and thin cylindrical rod is known to provoke a twisting instability, evolving from an initial kink to a knot. In the torsional parallel-plate rheometry of stubby cylinders, the geometrical constraints impose zero displacement of the axis of the cylinder, preventing the occurrence of such twisting instability. Under these experimental conditions, wrinkles occur on the cylinder's surface at a given critical angle of torsion. Here we investigate this subclass of elastic instability--which we call torsion instability--of soft cylinders subject to a combined finite axial stretch and torsion, by applying the theory of incremental elastic deformation superimposed on finite strains. We formulate the incremental boundary elastic problem in the Stroh differential form, and use the surface impedance method to build a robust numerical procedure for deriving the marginal stability curves. We present the results for a Mooney-Rivlin material and study the influence of the material parameters on the elastic bifurcation.

description: We study a non-Hermitian $PT-$symmetric generalization of an $N$-particle, two-mode Bose-Hubbard system, modeling for example a Bose-Einstein condensate in a double well potential coupled to a continuum via a sink in one of the wells and a source in the other. The effect of the interplay between the particle interaction and the non-Hermiticity on characteristic features of the spectrum is analyzed drawing special attention to the occurrence and unfolding of exceptional points (EPs). We find that for vanishing particle interaction there are only two EPs of order $N+1$ which under perturbation unfold either into $[(N+1)/2]$ eigenvalue pairs (and in case of $N+1$ odd, into an additional zero-eigenvalue) or into eigenvalue triplets (third-order eigenvalue rings) and $(N+1)\mod 3$ single eigenvalues, depending on the direction of the perturbation in parameter space. This behavior is described analytically using perturbational techniques. More general EP unfoldings into eigenvalue rings up to $(N+1)$th order are indicated.

description: We present a novel method for characterizing mammographic findings using spectral imaging without the use of contrast agent. Within a statistical framework, suspicious findings are analyzed to determine if they are likely to be benign cystic lesions or malignant tissue. To evaluate the method, we have designed a phantom where combinations of different tissue types are realized by decomposition into the material bases aluminum and polyethylene. The results indicate that the lesion size limit for reliable characterization is below 10 mm diameter, when quantum noise is the only considered source of uncertainty. Furthermore, preliminary results using clinical images are encouraging, but allow no conclusions with significance.

description: Recently, the United States - China trade dispute has emphasized the importance of Brazil as a major export competitor in the global soybean market. In this paper, we examine the time series characteristics of United States and Brazilian soybean basis markets for seasonality, changes in mean level, intermarket information flows, and other time series behavior. We specifically examined basis at 31 origins and 2 export locations in the United States and a primary export market in Brazil. The results strongly support the presence of analog seasonality indicating that seasonal patterns vary greatly from year-to-year at all locations. Time series intervention analysis indicates that the United States - China trade dispute had a significant lasting effect on the basis level in the Brazilian market but not in the United States. Granger causality analysis of information flows between the origin and export basis markets prior to and after the announcement of tariffs in the United States - China trade dispute shows a significant dampening effect upon the information flows between the markets following the announcement of tariffs. These results are useful in that they can provide guidance to market practitioners in modeling basis forecasts and also provide useful information regarding the impact of the recent United States – China dispute upon the behavior of these basis markets.

description: Landsat imagery is an unparalleled freely available data source that allows reconstructing horizontal and vertical urban form. This paper addresses the challenge of using Landsat data, particularly its 30m spatial resolution, for monitoring three-dimensional urban densification. We compare temporal and spatial transferability of an adapted DeepLab model with a simple fully convolutional network (FCN) and a texture-based random forest (RF) model to map urban density in the two morphological dimensions: horizontal (compact, open, sparse) and vertical (high rise, low rise). We test whether a model trained on the 2014 data can be applied to 2006 and 1995 for Denmark, and examine whether we could use the model trained on the Danish data to accurately map other European cities. Our results show that an implementation of deep networks and the inclusion of multi-scale contextual information greatly improve the classification and the model's ability to generalize across space and time. DeepLab provides more accurate horizontal and vertical classifications than FCN when sufficient training data is available. By using DeepLab, the F1 score can be increased by 4 and 10 percentage points for detecting vertical urban growth compared to FCN and RF for Denmark. For mapping the other European cities with training data from Denmark, DeepLab also shows an advantage of 6 percentage points over RF for both the dimensions. The resulting maps across the years 1985 to 2018 reveal different patterns of urban growth between Copenhagen and Aarhus, the two largest cities in Denmark, illustrating that those cities have used various planning policies in addressing population growth and housing supply challenges. In summary, we propose a transferable deep learning approach for automated, long-term mapping of urban form from Landsat images.

1H-MRS evaluation of the Phosphocreatine-Creatine (PCr/Cr) pool in human muscle
Creators: name: Trump, Mark Edward
Publisher: name: University of British Columbia
Year: 2009

description: Phosphocreatine (PCr) has been shown to effectively buffer ATP levels at high work rates in skeletal muscles. Our main goal was to assess whether or not the pool of PCr and Cr (Crtot) is the same in different metabolic states. Twelve healthy power trained (PWR) athletes (V02max 48 ± 1.9 ml/kg/min) and 12 healthy endurance trained (END) athletes (V02max 69.9 ± 1.5 ml/kg/min) completed a plantar flexion of the right foot against an increasing load until volitional fatigue. This was performed while lying supine in a 3 Tesla superconducting magnet with the gastrocnemius medialis (m. gastrocnemius), centered in a circumscribing coil. Total work production was calculated for the entire activity. Immediately following exhaustion a pressure cuff was inflated for 5 min (>350 mmHg superior to the knee) to allow collection of spectra prior to PCr resynthesis. A PRESS (Point Resolved Spectroscopy) sequence was used to resolve the 1H-visible Cr/PCr peak (3.02 ppm) during rest and ischemic fatigue. Standardized echo time (TE) of 100ms for 164 averages was used in collecting data from a 4.5 cm3 volume of interest (VOI) in the m. gastrocnemius. Upon removal of the cuff, recovery of Crtot was assessed for 10 min. Comparisons of rest vs. ischemic fatigue states in both groups indicated at least a 140% increase in the iH-MRS visible pool of Crtot. After 10 min of recovery the Crtot pool returned to within 27% of its resting state. These results suggest that there is a separate pool of Cr in the muscle which may be unavailable to creatine kinase until the onset of intense exercise. It is interesting to note that while both the transverse relaxation time (T2) for Crtot and the choline/carnitine/taurine peak (3.1 ppm) decreased by 65% and 26% respectively, the T2 of water was unchanged.

description: We study the spectrum of light plasmons in the (gapped and gapless) two-flavor color superconducting phases and its connection with the chromomagnetic instabilities and the structure of the ground state. It is revealed that the chromomagnetic instabilities in the 4-7th and 8th gluonic channels correspond to two very different plasmon spectra. These spectra lead us to the unequivocal conclusion about the existence of gluonic condensates (some of which can be spatially inhomogeneous) in the ground state. We also argue that spatially inhomogeneous gluonic condensates should exist in the three-flavor quark matter with the values of the mass of strange quark corresponding to the gapless color-flavor locked state.

description: We investigate the decidability and computational complexity of conservative extensions and the related notions of inseparability and entailment in Horn description logics (DLs) with inverse roles. We consider both query conservative extensions, defined by requiring that the answers to all conjunctive queries are left unchanged, and deductive conservative extensions, which require that the entailed concept inclusions, role inclusions, and functionality assertions do not change. Upper bounds for query conservative extensions are particularly challenging because characterizations in terms of unbounded homomorphisms between universal models, which are the foundation of the standard approach to establishing decidability, fail in the presence of inverse roles. We resort to a characterization that carefully mixes unbounded and bounded homomorphisms and enables a decision procedure that combines tree automata and a mosaic technique. Our main results are that query conservative extensions are 2ExpTime-complete in all DLs between ELI and Horn-ALCHIF and between Horn-ALC and Horn-ALCHIF, and that deductive conservative extensions are 2ExpTime-complete in all DLs between ELI and ELHIF_\bot. The same results hold for inseparability and entailment.

Electronic properties of substitutional impurities in graphene-like C$_2$N, $tg$-C$_3$N$_4$, and $hg$-C$_3$N$_4$

description: We study the electronic and structural properties of substitutional impurities of graphenelike nanoporous materials C$_2$N, $tg$-, and $hg$-C$_3$N$_4$ by means of density functional theory calculations. We consider four types of impurities; boron substitution on carbon sites (B(C)), carbon substitution on nitrogen sites (C(N)), nitrogen substitution on carbon sites (N(C)), and sulfur substitution on nitrogen sites (S(N)). From cohesive energy calculations, we find that the C(N) and B(C) substitutions are the most energetically favorable and induce small bond modifications in the vicinity of the impurity, while the S(N) induces strong lattice distortions. Though all of the studied impurities induce defect levels inside the band gap of these materials, their electronic properties are poles apart depending on the behavior of the impurity as an acceptor or a donor. It is also observed that acceptor (donor) wavefunctions are composed only of $σ$ ($π$) orbitals from the impurity itself and/or neighboring sites. Consequently, acceptor wavefunctions are directed towards the pores and donor wavefunctions are more extended throughout the neighboring atoms, a property that could further be explored to modify the interaction between these materials and adsorbates. Moreover, impurity properties display a strong site sensitivity and ground state binding energies ranging from $0.03$ to $1.13$ eV, thus offering an interesting route for tuning the optical properties of these materials. Finally, spin-polarized calculations reveal that all impurity configurations have a magnetic ground state that rises from the spin splitting of the impurity levels. In a few configurations, more than one impurity level can be found inside the gap and two of them could potentially be explored as two-level systems for single-photon emission, following similar proposals recently made on defect complexes on TMDCs.

description: Two general-relativistic hydrodynamical models are considered: a model of self-gravitating static configurations of perfect fluid and a model of steady accretion of fluid onto a black hole. We generalise analytic results obtained for the original polytropic versions of these models onto a wider class of barotropic equations of state. The knowledge about the polytropic solutions is used to establish bounds on certain characteristic quantities appearing in both cases.
