description: We introduce a family of methods for the full configuration interaction problem in quantum chemistry, based on the fast randomized iteration (FRI) framework [L.-H. Lim and J. Weare, SIAM Rev. 59, 547 (2017)]. These methods, which we term "FCI-FRI," stochastically impose sparsity during iterations of the power method and can be viewed as a generalization of full configuration interaction quantum Monte Carlo (FCIQMC) without walkers. In addition to the multinomial scheme commonly used to sample excitations in FCIQMC, we present a systematic scheme where excitations are not sampled independently. Performing ground-state calculations on five small molecules at fixed cost, we find that the systematic FCI-FRI scheme is 11 to 45 times more statistically efficient than the multinomial FCI-FRI scheme, which is in turn 1.4 to 178 times more statistically efficient than the original FCIQMC algorithm.

description: We examine the images of hundreds of planetary nebulae (PNe) and find that for about one in six PNe the morphology is too `messy' to be accounted for by models of stellar binary interaction. We speculate that interacting triple stellar systems shaped these PNe. In this preliminary study we qualitatively classify PNe by one of four categories. (1) PNe that show no need for a tertiary star to account for their morphology. (2) PNe whose structure possesses a pronounced departure from axial-symmetry and/or mirror-symmetry. We classify these, according to our speculation, as `having a triple stellar progenitor'. (3) PNe whose morphology possesses departure from axial-symmetry and/or mirror-symmetry, but not as pronounced as in the previous class, and are classified as `likely shaped by triple stellar system'. (4) PNe with minor departure from axial-symmetry and/or mirror symmetry that could have been as well caused by an eccentric binary system or the inter-stellar medium. These are classified as `maybe shaped by a triple stellar system'. Given a weight eta_t=1, eta_l=0.67, eta_m=0.33 to classes 2, 3 and 4, respectively, we find that according to our assumption about 13 - 21% of PNe have been shaped by triple stellar systems. Although in some evolutionary scenarios not all three stars survive the evolution, we encourage the search for a triple stellar systems at the center of some PNe.

Rademacher Complexity Bounds for a Penalized Multiclass Semi-Supervised Algorithm

description: We propose Rademacher complexity bounds for multiclass classifiers trained with a two-step semi-supervised model. In the first step, the algorithm partitions the partially labeled data and then identifies dense clusters containing $κ$ predominant classes using the labeled training examples such that the proportion of their non-predominant classes is below a fixed threshold. In the second step, a classifier is trained by minimizing a margin empirical loss over the labeled training set and a penalization term measuring the disability of the learner to predict the $κ$ predominant classes of the identified clusters. The resulting data-dependent generalization error bound involves the margin distribution of the classifier, the stability of the clustering technique used in the first step and Rademacher complexity terms corresponding to partially labeled training data. Our theoretical result exhibit convergence rates extending those proposed in the literature for the binary case, and experimental results on different multiclass classification problems show empirical evidence that supports the theory.

description: Visual Question Answering (VQA) is a recent problem in computer vision and natural language processing that has garnered a large amount of interest from the deep learning, computer vision, and natural language processing communities. In VQA, an algorithm needs to answer text-based questions about images. Since the release of the first VQA dataset in 2014, additional datasets have been released and many algorithms have been proposed. In this review, we critically examine the current state of VQA in terms of problem formulation, existing datasets, evaluation metrics, and algorithms. In particular, we discuss the limitations of current datasets with regard to their ability to properly train and assess VQA algorithms. We then exhaustively review existing algorithms for VQA. Finally, we discuss possible future directions for VQA and image understanding research.

Periodic asymptotic dynamics of the measure solutions to an equal mitosis equation

subject: FOS: Mathematics

description: We are interested in a non-local partial differential equation modeling equal mitosis. We prove that the solutions present persistent asymptoticoscillations and that the convergence to this periodic behavior, in suitable spaces of weighted signed measures, occurs exponentially fast. It can beseen as a result of spectral gap between the countable set of dominant eigenvalues and the rest of the spectrum, which is to our knowledge completely new. The two main difficulties in the proof are to define the projection onto the subspace of periodic (rescaled) solutions and to estimate thespeed of convergence to this projection. The first one is addressed by using the generalized relative entropy structure of the dual equation, and thesecond is tackled by applying Harris's ergodic theorem on sub-problems.

description: The Maritime Spatial Planning Directive (2014/89/EU) required European Union member states to finalise Marine Spatial Plans by 2021. These efforts have created new forums for considering synergies and conflicts around blue growth objectives at both national and local scales, but in many cases have consolidated management action at European or national levels. These nationalised MSP actions can conflict with the path dependence (legacy effects) of traditional industries. The preparation and publication of Ireland's National Marine Planning Framework (NMPF) provides rich examples of how the legacy effects of traditional rights of access and withdrawal can both inform and complicate planning goals. This research describes these interactions in the context of Ireland's seaweed sector. Efforts to equitably expand and manage Ireland's seaweed resource are hampered by controversy in the licensing of seaweed harvesting. Interviews with seaweed harvesting stakeholders were analysed using modified grounded theory, supplemented with critical analyses of the NMPF. Interviews made clear a longstanding and successful path dependence of community management of the Ireland's seaweed resource. However, national blue growth targets may conflict with local management traditions, alienating goal dependence between institutions and actors. These conflicts are exacerbated by national and exclusionary definitions of seaweed ownership. This work reveals conflicts between top-down management and local traditions of seaweed harvesting and provides recommendations as to how Irish legislation could prevent actor alienation from the management process by considering path dependence in management decisions and cultivating interdependent relationships to ensure seaweed harvester rights are respected in management plans.

description: With the help of the Berry curvature and the first Chern number $($$\textit{C}_1$$)$, we both analytically and numerically investigate and thus simulate artificial magnetic monopoles formed in parameter space of the Hamiltonian of a driven superconducting qubit. The topological structure of a spin-1/2 system $($qubit$)$ can be captured by the distribution of Berry curvature, which describes the geometry of eigenstates of the Hamiltonian. Degeneracy points in parameter space act as sources $($$\textit{C}_1$ = $1$$)$ or sinks $($$\textit{C}_1$ = $-1$$)$ of the magnetic field. We note that the strength of the magnetic field $($described by Berry curvature$)$ has an apparent impact on the quantum states during the process of topological transition. It exhibits an unusual property that the transition of the quantum states is asymmetric when the degenerate point passes from outside to inside and again outside the manifold spanned by system parameters. Our results also pave the way to explore intriguing properties of magnetic monopoles in other spin-1/2 systems.

description: Measuring the sum of the three active neutrino masses, $M_ν$, is one of the most important challenges in modern cosmology. Massive neutrinos imprint characteristic signatures on several cosmological observables in particular on the large-scale structure of the Universe. In order to maximize the information that can be retrieved from galaxy surveys, accurate theoretical predictions in the non-linear regime are needed. Currently, one way to achieve those predictions is by running cosmological numerical simulations. Unfortunately, producing those simulations requires high computational resources -- several hundred to thousand core-hours for each neutrino mass case. In this work, we propose a new method, based on a deep learning network, to quickly generate simulations with massive neutrinos from standard $Λ$CDM simulations without neutrinos. We computed multiple relevant statistical measures of deep-learning generated simulations, and conclude that our approach is an accurate alternative to the traditional N-body techniques. In particular the power spectrum is within $\simeq 6\%$ down to non-linear scales $k=0.7$~\rm h/Mpc. Finally, our method allows us to generate massive neutrino simulations 10,000 times faster than the traditional methods.

The mass distribution and gravitational potential of the Milky Way

Year: 2016
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: We present mass models of the Milky Way created to fit observational constraints and to be consistent with expectations from theoretical modelling. The method used to create these models is that demonstrated in McMillan (2011), and we improve on those models by adding gas discs to the potential, considering the effects of allowing the inner slope of the halo density profile to vary, and including new observations of maser sources in the Milky Way amongst the new constraints. We provide a best fitting model, as well as estimates of the properties of the Milky Way. Under the assumptions in our main model, we find that the Sun is $R_0 = (8.20\pm0.09)\,\mathrm{kpc}$ from the Galactic Centre, with the circular speed at the Sun being $v_0 = (232.8\pm3.0)\,\mathrm{km}\,\mathrm{s}^{-1}$; that the Galaxy has a total stellar mass of $(54.3\pm5.7)\times10^9\,{\rm M}_\odot$, a total virial mass of $(1.30 \pm 0.30)\times10^{12}\,{\rm M}_\odot$ and a local dark-matter density of $0.38\pm0.04\,\mathrm{GeV\,cm}^{-3}$, where the quoted uncertainties are statistical. These values are sensitive to our choice of priors and constraints. We investigate systematic uncertainties, which in some cases may be larger. For example, if we weaken our prior on $R_0$, we find it to be $(7.97\pm0.15)\,\mathrm{kpc}$ and that $v_0=(226.8\pm4.2)\,\mathrm{km}\,\mathrm{s}^{-1}$. We find that most of these properties, including the local dark-matter density, are remarkably insensitive to the assumed power-law density slope at the centre of the dark-matter halo. We find that it is unlikely that the local standard of rest differs significantly from that found under assumptions of axisymmetry. We have made code to compute the force from our potential, and to integrate orbits within it, publicly available.

description: The TROPOspheric Monitoring Instrument (TROPOMI) aboard the European Space Agency's Copernicus Sentinel-5 Precursor satellite, to be launched this year, mandates high-accuracy spectral reference data for CO and H2O in the 2.3µm region [1]. We present measurements of absorption line parameters for H2O and for the 2-0 rovibrational band of CO to be used in TROPOMI atmospheric retrievals. The experiments were carried out on a Bruker IFS 125HR Fourier transform spectrometer and a multispectrum fitting software developed at DLR was used for parameter retrieval [2] using the Hartmann-Tran-Profile [3,4].

In the case of carbon monoxide, we report line intensities, air-broadening and -shift parameters for lines of the 2-0 rovibrational band, which serve as a useful validation of the HITRAN2012 spectral database [5] while our analysis of Dicke narrowing, speed dependence and Rosenkranz line mixing  emphasizes the importance of modern line shape functions. Comparisons with previous studies of these non-Voigt parameters (e.g. [6]) show good agreement.

As for H2O, spectral parameters were measured in the 4190cm-1-4340cm-1 spectral range. Comparisons of measured line intensities of the ν3 band show remarkable agreement (<1.5% deviation on average) with ab initio values [7,8] and we will present air-broadening, -narrowing and -shift parameters together with their temperature dependences.

description: Polymorphic transitions in layered transition metal dichalcogenides provide an excellent platform for discovering exotic phenomena associated with metastable states, ranging from topological phase transitions to enhanced superconductivity. In particular, the transition from 2H to 1T'-MoTe$_2$, which was thought to be induced by high-energy photon irradiation among many other means, has been intensely studied for its technological relevance in nanoscale transistors. Despite the remarkable electrical performance arising from this 2H-to-1T' transition, it remains controversial whether a crystalline 1T' phase is produced because optical signatures of this putative transition are found to be associated with the formation of elemental Te clusters instead. Here, we demonstrate the creation of an intrinsic 1T' lattice after irradiating a mono- or few-layer 2H-MoTe$_2$ with a single field-enhanced terahertz pulse, whose low photon energy limits possible structural damage by optical pulses. To visualize the temporal evolution of this irreversible transition, we further develop a single-shot terahertz pump-second harmonic probe technique, and we find that the transition out of the 2H phase occurs within 10 ns after photoexcitation. Our results not only resolve the long-standing debate over the light-induced polymorphic transition in MoTe$_2$, they also highlight the unique capability of strong-field terahertz pulses in manipulating the structure of quantum materials.

description: We describe the automorphism groups of finite $p$-groups arising naturally via Hessian determinantal representations of elliptic curves defined over number fields. Moreover, we derive explicit formulas for the orders of these automorphism groups for elliptic curves of $j$-invariant $1728$ given in Weierstrass form. We interpret these orders in terms of the numbers of $3$-torsion points (or flex points) of the relevant curves over finite fields. Our work greatly generalizes and conceptualizes previous examples given by du Sautoy and Vaughan-Lee. It explains, in particular, why the orders arising in these examples are polynomial on Frobenius sets and vary with the primes in a nonquasipolynomial manner.

description: We analyse cosmological hydrodynamical simulations of galaxy clusters to study the X-ray scaling relations between total masses and observable quantities such as X-ray luminosity, gas mass, X-ray temperature, and $Y_{X}$. Three sets of simulations are performed with an improved version of the smoothed particle hydrodynamics GADGET-3 code. These consider the following: non-radiative gas, star formation and stellar feedback, and the addition of feedback by active galactic nuclei (AGN). We select clusters with $M_{500} > 10^{14} M_{\odot} E(z)^{-1}$, mimicking the typical selection of Sunyaev-Zeldovich samples. This permits to have a mass range large enough to enable robust fitting of the relations even at $z \sim 2$. The results of the analysis show a general agreement with observations. The values of the slope of the mass-gas mass and mass-temperature relations at $z=2$ are 10 per cent lower with respect to $z=0$ due to the applied mass selection, in the former case, and to the effect of early merger in the latter. We investigate the impact of the slope variation on the study of the evolution of the normalization. We conclude that cosmological studies through scaling relations should be limited to the redshift range $z=0-1$, where we find that the slope, the scatter, and the covariance matrix of the relations are stable. The scaling between mass and $Y_X$ is confirmed to be the most robust relation, being almost independent of the gas physics. At higher redshifts, the scaling relations are sensitive to the inclusion of AGNs which influences low-mass systems. The detailed study of these objects will be crucial to evaluate the AGN effect on the ICM.

description: The rise of deep learning in today's applications entailed an increasing need in explaining the model's decisions beyond prediction performances in order to foster trust and accountability. Recently, the field of explainable AI (XAI) has developed methods that provide such explanations for already trained neural networks. In computer vision tasks such explanations, termed heatmaps, visualize the contributions of individual pixels to the prediction. So far XAI methods along with their heatmaps were mainly validated qualitatively via human-based assessment, or evaluated through auxiliary proxy tasks such as pixel perturbation, weak object localization or randomization tests. Due to the lack of an objective and commonly accepted quality measure for heatmaps, it was debatable which XAI method performs best and whether explanations can be trusted at all. In the present work, we tackle the problem by proposing a ground truth based evaluation framework for XAI methods based on the CLEVR visual question answering task. Our framework provides a (1) selective, (2) controlled and (3) realistic testbed for the evaluation of neural network explanations. We compare ten different explanation methods, resulting in new insights about the quality and properties of XAI methods, sometimes contradicting with conclusions from previous comparative studies. The CLEVR-XAI dataset and the benchmarking code can be found at https://github.com/ahmedmagdiosman/clevr-xai.

Belastungen/Beanspruchungen wurden an 33 Teleheimarbeits- und alternierenden Telearbeitsplätzen sowie an 13 Kontrollarbeitsplätzen erhoben. Die Ergebnisse zeigen, dass sich die Belastungs- und Beanspruchungsprofile bei TA nur marginal von denen der Kontrollgruppe unterscheiden. Dabei verfügt die Gruppe der Teleheimarbeiter über einen größeren Zeitspielraum bei der Arbeit. Die soziale Unterstützung übt keinen moderierenden Effekt auf die Belastungs-Beanspruchungsrelation aus. Vor diesem Hintergrund werden abschließend einige der oft diskutierten Nachteile von Telearbeit diskutiert.
description: This article presents the first of eight waves of a longitudinal study with control groups on the evaluation and implementation of telework. We measured stress and strain of 33 telehome and alternating tele-workers, as well as of 13 persons in a control group. The results reveal marginal differences only in the stress and strain profiles between teleworkers and persons in the control group. Teleworkers report a better flexibility in their time-schedule during work. Social support has no moderating effect on the relation between stress and strain. The implications of these results for the critical debate of telework are discussed.

description: Behinderte Personen sind in vielen Lebensbereichen Benachteiligungen ausgesetzt, die sich auf das Stigma "Behinderung" zurückführen lassen. Integrationsfirmen bezeichnen eine qualitativ neue Beschäftigungsform auf dem ersten Arbeitsmarkt, die Benachteiligungen in beruflichen Kontexten entgegenwirken soll. Dabei leisten diese Firmen weitaus mehr, als "nur" die Konstituierung einer weiteren Beschäftigungsalternative: Über die Bereitstellung von Aktionsräumen, in denen Individualität unabhängig von sozialisierten Mustern geäußert werden kann, besitzen Integrationsfirmen erhebliches soziales Innovationspotential. Eine ungewöhnliche Organisationsstruktur, kollektiv etablierte Sinnkonstruktionen sowie redefinierte Interaktionsmuster fördern das Aufbrechen verfestigter Wahrnehmungsmuster, Individuation und damit Entstigmatisierung. Die Integrationsfirma ist dabei existenziell gezwungen, während der organisationalen Auseinandersetzung mit dem Phänomen Behinderung Konflikt- und Problemverarbeitungsmuster zu erarbeiten und einzusetzen, deren Qualitäten weit über den Kontext der Reintegration einer Randgruppe hinaus für Organisationen in turbulenten Umwelten von Bedeutung sein könnten.
description: Disabled people face many forms of discrimination in daily life. One basic reason for unfair treatment lies in the social definition and labeling of the stigma "to be disabled". Integration or self help firms characterize a qualitatively new approach concerning the integration of disabled people into the regular labour market without neglecting socio-psychological support. Therefore, they stand for another endeavour to neutralize discrimination on the labour market. Nevertheless, the achievement of the integration firm approach goes far beyond the establishment of "just" regular jobs. Integration firms open organizational space for enacting individuality without the determinant strictness of socialized behavioral patterns. Strange forms of organizational structure, collective sensemaking dynamics as well as redefined interaction patterns jeopardize established perception filters and encourage individuation and unstigmatization processes. While struggling with the stigma, the organization is forced to create and validate highly flexible and proactive patterns for internal conflict handling and problem solving. From that view, integration firms mark a social innovation potential not only for rehabilitative and integrative organizations.

description: We study the long-time behaviour of the growth-fragmentation equation, a nonlocal linear evolution equation describing a wide range of phenomena in structured population dynamics. We show the existence of a spectral gap under conditions that generalise those in the literature by using a method based on Harris's theorem, a result coming from the study of equilibration of Markov processes. The difficulty posed by the non-conservativeness of the equation is overcome by performing an $h$-transform, after solving the dual Perron eigenvalue problem. The existence of the direct Perron eigenvector is then a consequence of our methods, which prove exponential contraction of the evolution equation. Moreover the rate of convergence is explicitly quantifiable in terms of the dual eigenfunction and the coefficients of the equation.

description: Im nordrhein-westfälischen Modellversuch 'Meister-Studium', einer Innovation des dritten Bildungswegs, kann ein Studium ausschließlich aufgrund beruflicher Qualifikation aufgenommen werden. Hier wird der Frage nachgegangen, ob bei diesem `einfachen Weg zur Fachhochschule' gleiche Chancen für Männer und Frauen gegeben sind. Die geschlechtsspezifische Evaluierung zeigt, dass bereits die konzeptionelle Anlage des `Meister-Studiums' dazu beiträgt, Chancengleichheit zwischen Männern und Frauen zu verhindern. Auch die Umsetzung des Modellversuchs, als Folge der bisher praktizierten Weiterbildungsberatung und -politik, begünstigt Männer gegenüber Frauen. Die Evaluierung plädiert für die Etablierung einer Aufmerksamkeitsstruktur hinsichtlich der geschlechtsspezifischen Auswirkungen solcher Modellversuche.
description: The North Rhine-Westphalian pilot project Master Study is an innovation allowing professionals entrance into universities for applied science on the basis of their work-related qualifications. In this article the question is addressed if the Master Study, by providing easier access to the universities for applied science, contributes to the equality of men and women. A gender-specific evaluation shows that the conceptual framework of the model project in fact hinders equality between men and women. Furthermore, the Master Study, as implemented, builds on the preferential continuing education counseling and politics men receive over women. The relevance of the findings apply most importantly to creating a structure of attention with respect to the gender-specific effects of such model projects.

description: O trabalho de produção acadêmica consiste em analisar e discutir alguns aspectos que estão implícitos na Base Nacional Comum Curricular BNCC, aprovada pelo Conselho Nacional de Educação e homologada pelo Ministério da Educação, inicialmente no ano de 2017 com a educação infantil e ensino fundamental e, posteriormente em 2018, o ensino médio. Portanto, o referido documento, não se enquadra na perspectiva crítica-democrática, emancipadora e humanística, devido à sua complexidade, incompletude e limitações, além do que, é uma decisão política e ideológica de maneira verticalizada, colocando os educadores frente a vários desafios, não perspectivados. Por isso, torna-se necessário à sua ressignificação e uma profunda ampliação do diálogo para assegurar a qualidade social da educação básica, pública e gratuita.

description: This is the challenge design document for the "Automated Segmentation Of Coronary Arteries" Challenge, accepted for MICCAI 2020. Cardiovascular disease is a major cause of death. Medical imaging such as Computed Coronary Tomography
 Angiography (CCTA) is often used to evaluate the severity of coronary artery disease. Due to the non-invasive
 nature of CCTA, it is also commonly used for evaluating and reconstructing heart and coronary vessel structures.
 Coronary artery tree models have a wide array of applications in anatomy, physiology and pathophysiology for
 educational, training and research purposes; Including study of anatomy of coronary vessels and effects of disease
 on anatomy, developing machine learning models for disease risk prediction, education and training of medical
 professionals, In-silico testing of medical devices and 3D printing models for testing and education.
 Due to the small size of coronary arteries, possible disease and image artefacts, segmentation of coronary arteries
 has been focused on semi-automatic methods where a human expert guides the algorithm and corrects errors.
 This severely limits large scale processing of medical images and possibility of integration with clinical systems.
 Previous challenges have been focused on specific tasks such as centreline extraction, stenosis quantification and
 segmentation of specific artery segments. However, to our knowledge this is the first challenge focused on
 developing fully automatic segmentation methods of the full coronary artery tree. This challenge aims to establish
 a large standardized annotated dataset of healthy and diseased coronary vessels and utilize this dataset to develop
 fully automated segmentation algorithms. Automated segmentation would allow processing the large number of
 CCTAs available to create larger datasets for use cases mentioned above.

description: We propose a unified approach to prove general formulas for the joint distribution of an Eulerian and a Mahonian statistic over a set of colored permutations by specializing Poirier's colored quasisymmetric functions. We apply this method to derive formulas for Euler-Mahonian distributions on colored permutations, derangements and involutions. A number of known formulas are recovered as special cases of our results, including formulas of Biagioli-Zeng, Assaf, Haglund-Loehr-Remmel, Chow-Mansour, Biagioli-Caselli, Bagno-Biagioli, Faliharimalala-Zeng. Several new results are also obtained. For instance, a two-parameter flag major index on signed permutations is introduced and formulas for its distribution and its joint distribution with some Eulerian partners are proven.

description: The strong isomorphism classes of extensions of finite groups are parametrized by orbits of a prescribed action on the second cohomology group. We study these orbits in the case of extensions of a finite abelian $p$-group by a cyclic factor of order $p$. As an application, we compute number and sizes of these orbits when the initial $p$-group is generated by at most $3$ elements.

description: In this article we study automorphisms and endomorphisms of lacunary hyperbolic groups. We prove that every lacunary hyperbolic group is Hopfian, answering a question by Henry Wilton. In addition, we show that if a lacunary hyperbolic group has the fix point property for actions on $\mathbf R$-trees, then it is co-Hopfian and its outer automorphism group is locally finite. We also construct lacunary hyperbolic groups whose automorphism group is infinite, locally finite, and contains any locally finite group given in advance.

description: We study the Modular Isomorphism Problem applying a combination of existing and new techniques. We make use of the small group algebra to give a positive answer for two classes of groups of nilpotency class 3. We also introduce a new approach to derive properties of the lower central series of a finite $p$-group from the structure of the associated modular group algebra. Finally, we study the class of so-called $p$-obelisks which are highlighted by recent computer-aided investigations of the problem.

description: جاءت هذه الدراسة حول الغزو الروسي لأوكرانيا للبحث في الآثار الاقتصادي للعقوبات الغربية على الاقتصاد الروسي خلال الفترة من 24 فيفري إلى منتصف شهر مارس من سنة 2022. ولتحقيق أهداف الدراسة تم استقراء عدد من البيانات والتقارير الصادرة عن جهات رسمية. أظهرت نتائج الدراسة، أنّه وبالرغم من حجم التضييق المفروضة على الاقتصاد الروسي، إلا أنّه استطاع الصمود خلال هذه الفترة، وهذا نتيجة ما عرفه الاقتصاد الروسي من تطور، وكذا ابتعاده عن التبعية للدول الغربية مؤخرًا، من خلال وضع البدائل الكفيلة بتحقيق الإدارة الجيدة لاقتصادها. وقد اقترحت الدراسة في الأخير أنّه على الحكومة الجزائرية حاليًا أنّ تحافظ على علاقتها مع جميع الأطراف، وأنّ تسعى مستقبلًا لتخفيف من تبعيتها المفرطة، وأنّ تعمل على تنويع اقتصادها. This early study on the Russian invasion of Ukraine came to search for the economic effects of Western sanctions on the Russian economy during the period from February 24 to mid-March 2022. By extrapolating a number of reports issued by official authorities.We concluded that despite the restrictions on the Russian economy, it was able to withstand, and this is a result of the development of the Russian economy and its distance from dependence on Western countries recently, by developing alternatives that ensure good management of its economy. Finally, the study suggested that the Algerian government should currently maintain its relationship with all parties, and seek in the future to reduce its excessive dependence on countries, and work to diversify its economy.
