description: In this paper we consider the use of extended formulations in LP-based algorithms for mixed integer conic quadratic programming (MICQP). Extended formulations have been used by Vielma, Ahmed and Nemhauser (2008) and Hijazi, Bonami and Ouorou (2013) to construct algorithms for MICQP that can provide a significant computational advantage. The first approach is based on an extended or lifted polyhedral relaxation of the Lorentz cone by Ben-Tal and Nemirovski (2001) that is extremely economical, but whose approximation quality cannot be iteratively improved. The second is based on a lifted polyhedral relaxation of the euclidean ball that can be constructed using techniques introduced by Tawarmalani and Sahinidis (2005). This relaxation is less economical, but its approximation quality can be iteratively improved. Unfortunately, while the approach of Vielma, Ahmed and Nemhauser is applicable for general MICQP problems, the approach of Hijazi, Bonami and Ouorou can only be used for MICQP problems with convex quadratic constraints. In this paper we show how a homogenization procedure can be combined with the technique by Tawarmalani and Sahinidis to adapt the extended formulation used by Hijazi, Bonami and Ouorou to a class of conic mixed integer programming problems that include general MICQP problems. We then compare the effectiveness of this new extended formulation against traditional and extended formulation-based algorithms for MICQP. We find that this new formulation can be used to improve various LP-based algorithms. In particular, the formulation provides an easy-to-implement procedure that, in our benchmarks, significantly improved the performance of commercial MICQP solvers.

description: We present a satisfiability tester QSAT for quantified Boolean formulae and a restriction of QSAT to unquantified conjunctive normal form formulae. QSAT makes use of procedures which replace subformulae of a formula by equivalent formulae. By a sequence of such replacements, the original formula can be simplified to or . It may also be necessary to transform the original formula to generate a subformula to replace. eliminates collections of variables from an unquantified clause form formula until all variables have been eliminated. QSAT and can be applied to hardware verification and symbolic model checking. Results of an implementation of are described, as well as some complexity results for QSAT and . QSAT runs in linear time on a class of quantified Boolean formulae related to symbolic model checking. We present the class of “long and thin” unquantified formulae and give evidence that this class is common in applications. We also give theoretical and empirical evidence that is often faster than Davis and Putnam-type satisfiability checkers and ordered binary decision diagrams (OBDDs) on this class of formulae. We give an example where is exponentially faster than BDDs.

description: Recent theoretical studies have predicted magnetic states for Ru and Os in the body centered tetragonal structure (bct) with c/a < 1. In this study, we present first principles calculations of the phonon dispersion for ferromagnetic Ru- and Os-bct along the epitaxial and uniaxial Bain paths, to evaluate their dynamical stability. The phonon dispersions were computed using the density function perturbation theory, including the gradient corrections to the exchange-correlation functional within the plane-waves ultrasoft-pseudopotential approximation. The phonon dispersion for the local minimum in the Bain path with c/a < 1 as well as the uniaxial and epitaxial strained structures are analyzed. We find imaginary frequencies along different directions of the Brillouin zone, which indicates that both systems are dynamically unstable. Consequently, ferromagnetic Ru and Os in the body centered tetragonal structure with c/a < 1 are not truly metastable phases.

description: Les monopieux utilisés comme fondations pour les éoliennes offshore sont souvent installés dans le fond marin par battage. Au cours de l’exploitation des éoliennes, les monopieux sont soumis à des chargements horizontaux importants dus aux vents, aux courants et aux vagues. Cependant, le comportement latéral du monopieu est complexe en particulier pour de faibles profondeurs d’encastrement (tendance actuelle des applications industrielles). C’est pourquoi un dispositif expérimental embarqué en centrifugeuse a été conçu pour examiner la réponse horizontale d’un monopieu battu à l’échelle 1/100 (prototype de 5 m de diamètre D) dans du sable dense saturé. En particulier, l'effet (i) de l'installation par battage jusqu’à 5D de profondeur, et (ii) de la profondeur d'encastrement (L/D = 3 à 5) sur la réponse latérale du monopieu sont étudiées en utilisant un monopieu instrumenté par fibres optiques. En outre, les résultats expérimentaux sont comparés avec la méthode de conception PISA en réalisant un modèle numérique aux éléments finis 1D.

description: Hydroxy fatty acids (HFAs) are major chemical feedstocks for industries manufacturing cosmetics, paints, polymers and resins. Currently, Ricinus communis (Castor) is the only agronomic source of HFA but cultivation of castor is banned in US due to the presence of toxin in its seed. Physaria fendleri (Lesquerella) is a native plant from southwest US, non-toxic, and accumulates about 60% hydroxy fatty acids in its seed oil/triacylglycerol (TAG). However, P. fendleri is not a crop and requires breeding or engineering to be a high yielding oilseed crop. Therefore, it is important to understand the triacylglycerol assembly pathway involved in accumulation of HFA in P. fendleri seeds. Castor uses linear Kennedy pathway with efficient acyl-editing to accumulate triacylglycerol with HFAs whereas other oilseed plants use membrane lipid phosphatidylcholine (PC) as an intermediate to make TAG without HFAs. Most plants keep HFAs out of their membrane lipids so, P. fendleri was thought to use linear Kennedy pathway as castor to avoid unusual fatty acids in membrane lipids. But seed transcriptomics data suggested that expression of TAG assembly genes in P. fendleri are similar to other brassica species which use PC-derived DAG (diacylglycerol) pathway, thus making TAG assembly pathway in P. fendleri unclear. Metabolic labeling experiments using radioactive substrates in developing seeds demonstrated that P. fendleri uses a novel pathway known as TAG remodeling to make final TAG molecule containing two HFAs. In the TAG remodeling pathway, PC is used as an intermediate to first make 1HFA-TAG, subsequently a non-hydroxy fatty acid is removed and replaced with a second hydroxy fatty acid to make the final 2HFA-TAG species. A triacylglycerol lipase and acyl-CoA:diacylglycerol acyltransferase (DGAT) might work in tandem for TAG remodeling mechanism. Protein-protein interactions studies using Yeast two-hybrid and Bimolecular fluorescence complementation assays were able to identify the candidate genes for TAG remodeling. Green fluorescent protein (GFP) fused version of these candidate genes were used for their subcellular localization in tobacco leaves. In addition to identifying possible genes, Arabidopsis thaliana HFA line overexpressing those candidate enzymes from P. fendleri were used to test if TAG remodeling can be reconstituted in a different species.

description: The research was carried out at NPIUB research laboratory, Dept. of Food Engineering, NPI university of Bangladesh, Manikgonj, Bangladesh, during June-July 2020. The quality of Mustard oils was analyzed by evaluating physicochemical properties such as density, moisture content, reflexive index, peroxide values, acid values and iodine values using standard methods.In this study oils from selected mustard seeds investigated to determine the physicochemical properties like density, moisture content, reflexive index, saponification value (SV), peroxide value (PV), acid value (AV) and iodine value (IV). Highest density observed in (Red(Local)80%+Red(Hybrid)20%)- mustard oil (0.92 g/ml) and lowest in (Red(Local)75%+White(Local)25%)- mustard oil (0.91 g/ml). On the other hand, moisture content was observed in between 0.17% to 0.19% & (Red(Local)100%)- mustard oil (0.15%). It was observed that (Red(Local)75%+White(Local)25%)- mustard oil showed maximum (1.19 meq O2/kg) and (Red(Local)80%+Red(Hybrid)20%)- mustard oil showed minimum (1.18 meq O2/kg) peroxide values. Highest acid value was observed in (Red(Local)-100%) mustard oil (2.01 mg KOH/g) and lowest in (Red(Local)75%+White(Local)25%)- mustard oil (1.3 mg KOH/g). Highest iodine value was observed in (Red(Local)80%+Red(Hybrid)20%)- mustard oil (102.4 g I2/g oil) and lowest in (Red(Local)75%+White(Local)25%)- mustard oil (99.7 g I2/g oil). The results will help us for selecting a good quality of Mustard oil from the differences kind of Mustard seeds.
La Palygorskite calcinée comme ajout cimentaire : une étude comparative avec le métakaolin

description: L'utilisation d'argiles calcinées comme supplementary cementitious materials (SCMs) est une technologie aujourd’hui bien connue qui permets de diminuer l’empreinte environnementale du ciment. Le métakaolin (résultant de la calcination de la Kaolinite) est l'argile calcinée qui présente le plus grand potentiel pour une utilisation comme SCM. Cependant, l’étude de l'utilisation de nouvelles argiles comme ajouts cimentaires est essentielle pour développer des ciments plus durables dans les régions où le kaolin n'est pas disponible. Cette étude examine l'utilisation comme ajout cimentaire d’une Palygorskite (dont la réactivité en milieu cimentaire n'a encore jamais été étudiée) et compare les résultats à la référence actuelle qu’est le métakaolin. La calcination, la réactivité pouzzolanique et les performances mécaniques en système cimentaire ont été étudiées. Les résultats montrent que la Palygorskite se comporte très différemment de la Kaolinite pendant la calcination et présente une cinétique de déshydroxylation plus longue et graduelle. Bien que la Palygorskite calcinée n'atteigne pas la pouzzolanicité élevée du métakaolin, elle se classe parmi les SCMs hautement réactifs, permettant une augmentation significative des performances mécaniques sur des pâtes incorporant seulement 10% de Palygorskite calcinée. Il apparaît donc que la Palygorskite calcinée peut être un SCM approprié une fois calcinée, ce qui pourrait à terme permettre de proposer de nouvelles alternatives au métakaolin.

description: Le béton drainant est un matériau en constante augmentation car il présente des avantages environnementaux, tels que la réduction du bruit, la gestion des eaux pluviales et la limitation des polluants. Il présente aussi des avantages pour lutter contre les îlots de chaleur urbains (ICU), mais jusqu’à présent, peu d’études ont été faites. L’objectif de ce travail est d’étudier le comportement thermique du béton drainant à base de gravier naturel (BD) en conditions sèche et humide afin de réduire les effets de l’ICU. Un modèle analytique est proposé. Il est validé par des mesures obtenus en condition sèche à partir d’un banc expérimental innovant développé spécialement pour cette étude. Une étude de sensibilité de paramètres menée sur la base du modèle analytique en condition sèche montre que la température de surface du BD est plus sensible aux variations de l’albédo qu’à celles de la conductivité thermique. En condition humide, les résultats montrent que l’effet de refroidissement par évaporation du BD est efficace pendant trois jours. Cet effet est conditionné par la présence de l’eau près de la surface.

description: Hempcrete is known for its advantages in the field of construction, but the lack of standards on this material leads to a lack of guarantees on site. Nowadays, professionals use a sensible approach to evaluate the drying of hempcrete. The goal of this research is to propose a relevant method to assess the water content by in-situ measurements with usual devices. A wood moisture meter was calibrated for hempcrete in order to monitor the drying of a hempcrete screed and enhance the existing database on the hydric transfer mechanisms in hempcrete.

description: By synchronizing a microwave waveform with the synchrotron x-ray pulses, we use the ferromagnetic resonance (FMR) of the Py (Ni81Fe19) layer in a Py/Cu/Cu75Mn25/Cu/Co multilayer to pump a pure spin current into the Cu75Mn25 spacer layer, and then directly probe the spin current in the Cu75Mn25 layer by a time-resolved x-ray magnetic circular dichroism (XMCD). This element-specific pump-probe measurement unambiguously identifies the AC spin current in the Cu75Mn25 layer. In addition, phase resolved x-ray measurements reveal a characteristic bipolar phase behavior of the Co spins that is a fingerprint of spin-current driven spin precession.

Plusieurs phénomènes physico-chimiques et mécaniques se produisent durant la carbonatation d’un mortier de ciment. Pour les étudier, des échantillons de mortier sont soumis à la carbonatation accélérée afin de suivre l’évolution de leur retrait en fonction du degré de carbonatation. Dans un premier temps, la carbonatation de la portlandite et la précipitation de la calcite dominent et sont accompagnés d’un léger retrait de carbonatation. Par la suite, la carbonatation des C-S-H devient prépondérante conduisant à la formation de vatérite et d’aragonite ainsi qu’au développement un fort retrait de carbonatation favorisant l’apparition de microfissures.

description: En France, le secteur du bâtiment existant représente environ 45% de la consommation d’énergie finale. Ainsi, d’importantes économies d’énergie peuvent être réalisées dans ce secteur. Un des leviers d’actions consiste à améliorer l’isolation des bâtiments. Pour cela, nous proposons une méthode active couplant mesures et modèles physiques afin d’identifier in-situ sur un temps court la résistance thermique de parois avant et après une action de rénovation. Dans ce papier, trois méthodes inverses sont proposées et comparées à l’aide d’essais virtuels sur des parois de type « isolation thermique intérieur » (ITI) et mono-mur. Les premiers résultats montrent que les modèles RC peuvent être utilisés afin d’identifier, avec une bonne précision et à moindre coût de calcul, la résistance thermique de parois ITI. Par contre, un modèle basé sur les équations de la chaleur en unidimensionnel doit être privilégié pour les parois mono-murs.

description: This paper derives a novel formulation of the depth-averaged shallow water equations with anisotropic porosity for computational efficiency reasons. The aim is to run simulations on coarser grids while maintaining an acceptable accuracy through the introduction of porosity terms, which account for subgrid-scale effects. The porosity is divided into volumetric and areal porosities, which are assigned to the cell volume and the cell edges, respectively. The former represents the volume in the cell available to flow and the latter represents the area available to flow over an edge, hence introducing anisotropy. The porosity terms are variable in time in dependence of the water elevation in the cell and the cumulative distribution function of the unresolved bottom elevation. The main novelty of the equations is the formulation of the porosities which enables full inundation of the cell. The applicability of the equations is verified in five computational examples, dealing with dam break and rainfall-runoff simulations. Overall, good agreement between the model results and a high-resolution reference simulation has been achieved. The computational time decreased significantly: on average three orders of magnitude.
Geometric construction of some families of two-class and three-class association schemes and codes from nondegenerate and degenerate Hermitian varieties
Creators: name: Chakravarti, I.M.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1993

description: Taking a nondegenerate Hermitian variety as a projective set in a projective plane PG(2,s2), Mesner (1967) derived a two-class association scheme on the points of the affine space of dimension 3, for which the projective plane is the plane at infinity.We generalize his construction in two ways. We show how his construction works both for nondegenerate and degenerate Hermitian varieties in any dimension.We consider a projective space of dimension N, partitioned into an affine space of dimension N and a hyperplane H of dimension N − 1 at infinity.The points of the hyperplane are next partitioned into 2 or 3 subsets. A pair of points a,b of the affine space is defined to belong to class i if the line ab meets the subset i of H.In the first case, the two subsets of the hyperplane are a nondegenerate Hermitian variety and its complement. In this case, we show that the classification of pairs of affine points defines a family of two-class association schemes. This family of association schemes has the same set of parameters as those derived as restrictions of the Hamming association schemes to two-weight codes defined as linear spans of coordinate vectors of points on a nondegenerate Hermitian variety in a projective space of dimension N − 1. The relations of these codes to orthogonal arrays and difference sets are described in [5,6].In the second case, the three subsets are the singular point of the variety, the regular points of the variety and the complement of the variety defined by a Hermitian form of rank N − 1. This leads to a family of three-class association schemes on the points of the affine space. A geometric construction is first given for the case N = 3.Using a general algebraic method pointed out by the referee, we have also derived the three-class association scheme for general N.

title: Molecular studies on the control of the expression of the NPY-Y1 receptor gene

Publisher: name: University of Glasgow
Year: 1997
Subjects: subject: Genetics.

description: The cDNA that encodes for the rat NPY-Y1 receptor has been reported (Eva at al., 1990) and predicts a classical G-protein coupled receptor. This receptor has been linked to important physiological process in the nervous system (Grundemar and Hakanson, 1994). In this thesis the gene that encodes for the promoter of the rat NPY-Y1 receptor was obtained by PCR subcloning. (i) This region contains several consensus sequences for transcription factors: a "TATA-like" box, a "CAAT-like" box, an Sp1 site, an AP1 site, two CRE elements, a non-palindromic ERE and four non-palindromic GRE. (ii) This region has been attached to the reporter function, luciferase, so that the expression of this enzyme has been placed under the control of the promoter region of the NPY-Y1 receptor (pY1-LUC). (iii) The pY1-LUC has been transiently transfected into PC12 cells, a rat phaeochromocytoma cell line (Greene and Tischler, 1976), GTl-7 cells, a mouse hypothalamic cell line (Mellon et al., 1990) and RINm5f cells, a rat beta-pancreatic cell line (Poliak et al., 1993) which express constitutive levels of the NPY-Y1 receptor. It is thus possible to measure the basal transcriptional activity of this gene and study the factors which affect its transcriptional levels in these cells. (iv) Differentiation of the cells into an adrenal chromaffin-like phenotype with dexamethasone and in a neuronal-like phenotype with NGF or PACAP increased the transcriptional activity of the NPY-Y1 gene in PC 12 cells. Moreover, activation of PKA with DBC or forskolin, and activation of PKC with DH1 or PMA also increased the expression of this gene in PC12 cells. (v) The transcriptional response to NGF was dependent on trk A receptor and PKC activation but independent of ras-MAPK activation. Moreover, the effect of PACAP-38 was dependent in both PKA and PKC activation, but is also independent in ras-MAPK activation. Thus, the transcription of the NPY-Y1 receptor its under tight regulation by the glucocorticoid receptor, PKA and PKC signalling in a sympatho-adrenal model system, PC 12 cells.

description: We examine the concept of black hole thermodynamic volume and its consistency with thermodynamic mass in spacetimes that are not asymptotically flat but instead have anisotropic Lifshitz scaling symmetry. We find that the generalized Smarr relation in anti de Sitter space -- extended to include a pressure-volume term -- holds here as well, and that there exists a definition of thermodynamic mass and thermodynamic volume that satisfy both this relation and the $1^{st}$ law of thermodynamics. We compare the thermodynamic mass with other known quantities such as ADM, Brown-York and Hollands-Ishibashi-Marolf masses. We also conjecture methods for obtaining a thermodynamic mass where there is ambiguity due to the cosmological constant lengthscale depending on the horizon radius lengthscale.

description: The Directive on Copyright in the Digital Single Market has been a subject of heated and highly polarised debate, and an object of intense lobbying from the outset. It grasped the attention of a multitude of stakeholders, including tech companies, publishers, platforms, creators and SMEs, and urged thousands of people to go out on the streets in a sign of protest against what they believed was the “end of the internet as we know it”. The debate was often emotional, and involved such terms as “meme ban”, “censorship”, “upload filters”, “link tax”, or a puzzling “value gap”. However, amongst those emotive catchphrases lies a foundational discussion on the purposes of copyright law, and how its relationship with artists, technology, media, news, culture and citizenship unfolded. In this presentation, we investigate how discourse developed during the negotiation phase of the Directive, focusing on the most controversial provisions: draft Articles 11 (press publishers’ right) and 13 (platform liability). Focusing on the period between publication of the proposal by the Commission in September 2016, and the adoption of the Directive by Parliament and Council in March/April 2019, we juxtapose these changes with an analysis of (1) parliamentary debates, (2) press releases by the Commission, Parliament and Council, and (3) 80 stakeholder submissions that sought to shape the evolving legislation. Through discourse analysis, we uncover four topoi that appear to dominate the debate: (a) Technocratic (responding to tech development by updating the copyright framework), (b) Value gap (the redistribution of revenues to benefit creators and producers), (c) Internet freedoms (freedom of expression and user interests), and (d) European (the promotion and protection of European culture and identity). Finally, we show that changes in the Directive’s text can be associated with the appearance and evolution of the discourse. We show that changes in the draft legislation can be associated with the appearance and evolution of the four topoi in the debates, but that changes in the proposed legal language tend to be obfuscatory, rather than addressing the issues. Controversial language such as “content identification” (associated with filtering) was removed and safeguards were offered, but many of these changes remained meaningless (in law) or open to different implementations.

description: Effluents of waste products coming from pharmaceutical industry enter environmental ecosystems through various channels such as pharmaceutical equipments, wastewater treatment plants and medical center wastes. During the last few decades, the production and consumption of pharmaceutical products have drastically increased due to the considerable usage of medical products by the fast growing world population. Today, large quantities of medical products are produced each year for human and animal healthcare. As a result of the production and use of antibiotics, a large amount of antibiotic-containing wastewater is generated. These waters are discharged into the environment and cause serious pollution. Antibiotics cannot be treated with conventional wastewater treatment technology such as physical adsorption, chemical reactions, and biodegradation due to their tenacity and chemical stability. Therefore, more effective treatment methods need to be developed to remove its from water. Advanced oxidation processes (AOPs) is an environmentally friendly technology for removing stubborn pollutants. In this study, the treatability of antibiotics in wastewater with advanced oxidation processes was evaluated. Studies with different types of antibiotics were examined and the methods used in treatment were compared and their removal efficiencies were evaluated. This study will be a resource for researchers who will purify with advanced oxidation method.

description: We present Keck-I MOSFIRE spectroscopy in the Y and H bands of GDN-8231, a massive, compact, star-forming galaxy (SFG) at a redshift $z\sim1.7$. Its spectrum reveals both H$_α$ and [NII] emission lines and strong Balmer absorption lines. The H$_α$ and Spitzer MIPS 24 $μ$m fluxes are both weak, thus indicating a low star formation rate of SFR $\lesssim5-10$ M$_{\odot}$ yr$^{-1}$. This, added to a relatively young age of $\sim700$ Myr measured from the absorption lines, provides the first direct evidence for a distant galaxy being caught in the act of rapidly shutting down its star formation. Such quenching allows GDN-8231 to become a compact, quiescent galaxy, similar to 3 other galaxies in our sample, by $z\sim1.5$. Moreover, the color profile of GDN-8231 shows a bluer center, consistent with the predictions of recent simulations for an early phase of inside-out quenching. Its line-of-sight velocity dispersion for the gas, $σ^{\rm{gas}}_{\!_{\rm LOS}}=127\pm32$ km s$^{-1}$, is nearly 40% smaller than that of its stars, $σ^{\star}_{\!_{\rm LOS}}=215\pm35$ km s$^{-1}$. High-resolution hydro-simulations of galaxies explain such apparently colder gas kinematics of up to a factor of $\sim1.5$ with rotating disks being viewed at different inclinations and/or centrally concentrated star-forming regions. A clear prediction is that their compact, quiescent descendants preserve some remnant rotation from their star-forming progenitors.

description: Recent synthetic speech detectors leveraging the Transformer model have superior performance compared to the convolutional neural network counterparts. This improvement could be due to the powerful modeling ability of the multi-head self-attention (MHSA) in the Transformer model, which learns the temporal relationship of each input token. However, artifacts of synthetic speech can be located in specific regions of both frequency channels and temporal segments, while MHSA neglects this temporal-channel dependency of the input sequence. In this work, we proposed a Temporal-Channel Modeling (TCM) module to enhance MHSA's capability for capturing temporal-channel dependencies. Experimental results on the ASVspoof 2021 show that with only 0.03M additional parameters, the TCM module can outperform the state-of-the-art system by 9.25% in EER. Further ablation study reveals that utilizing both temporal and channel information yields the most improvement for detecting synthetic speech.

Max-balanced flows in oriented matroids

description: Let M=(E,O) be an oriented matroid on the ground set E. A real-valued vector x defined on E is a max-balanced flow for M if for every signed cocircuit Y∈O⊥, we have maxeεY+Xe=maxeεY−Xe. We extend the admissibility and decomposition theorems of Hamacher from regular to general oriented matroids in the case of max-balanced flows, which gives necessary and sufficient conditions for the existence of a max-balanced flow x satisfying l⩽×⩽u. We further investigate the semilattice of such flows under the usual coordinate partial order, and obtain structural results for the minimal elements. We also give necessary and sufficient conditions for the existence of such a flow when we are allowed to reverse the signs on a subset F⊆E. The proofs of all of our results are constructive, and yield polynomial algorithms in case M is coordinatized by a rational matrix A. In this same setting, we describe a polynomial algorithm that for a given vector w defined on E, either finds a potential p such that w′=w+pA is max-balanced, or a certificate that M has no max-balanced flow.

Restricted baby Skyrme-Maxwell theory in a magnetic medium: BPS configurations and some properties

description: We study the existence of BPS configurations in a restricted baby Skyrme-Maxwell enlarged via the inclusion of a nontrivial magnetic permeability. In order to attain such a goal, we use the Bogomol'nyi-Prasad-Sommerfield prescription, which allows us to obtain the lower bound for the energy and the BPS equations whose [electrically neutral] solutions saturate that bound. During the energy minimization procedure, we find a differential constraint which involves the self-dual potential, the superpotential itself and also the magnetic permeability. In order to solve the BPS system, we focus our attention on those solutions with rotational symmetry. For that, we fix the magnetic permeability and select two BPS potentials which exhibit a similar behavior near to the vacuum. We depict the resulting profiles and proceed to an analytical description of the properties of the BPS magnetic field. Furthermore, we consider some essential aspects of our model, such as the conditions for the overall existence of the BPS solutions, and how the permeability affects the magnetic flux. Finally, we present a family of exact BPS solutions.
