The Orbit Galaxy XTRASOFT Coils: A Multicenter Study of Coil Safety and Efficacy in Both Ruptured and Unruptured Cerebral Aneurysms
Creators: name: Zeenat Qureshi Stroke Institutes
Publisher: name: Zenodo
Year: 2023

description: Increase packing density with the use of softer three-dimensional (3D) coils has been indicated in reducing aneurysm recurrence. We are reporting a multicenter initial experience of using the Orbit Galaxy XTRASOFT which is a stretch-resistant, softer 3D coil in both ruptured and unruptured aneurysms. A total of 57 consecutive patients from five high-volume neurointerventional centers were reported where at least one Galaxy XTRASOFT coil was used during a procedure. There were 25 patients with ruptured aneurysm and 32 with elective coiling. The overall complication rate was 3.5%, one patient with nonoperative retroperitoneal hematoma and one patient with intraoperative rupture but with no neurological deficit. The occlusion rate of 90% or greater was achieved in 86% of the cases. The discharge modified Rankin score of 0 or 1 was achieved in 100% of the elective coiling and 65% in the ruptured cases. Early experience with Galaxy XTRASOFT coils for both ruptured and unruptured aneurysms appears to be safe with good aneurysm obliteration and low complication rate.

description: Management information systems are computer systems within an organisation that incorporate both hardware and software operations. It involves using business processes, people, and technology to collect, record, process, and store essential data that is significant to decision-making processes (Hartanto and Asmuni, 2017, 11). Management information systems are also used to coordinate, analyse, control, and visualise crucial organisational information. The ultimate goal of using MIS within the corporate environment is to increase value creation and profit earnings for businesses. Information systems play a significant role in helping global organisations become competitive and innovative because of their capacity to enable multinational corporations to develop superior business coordination skills necessary for the management of a global economy (Laudon and Laudon, 2013, 19). Organisations that have adopted effective information systems have a superior capacity to collect, analyse, visualise, and store appropriate market data that they can use to enhance efficient functioning and competitive position.

description: The United Kingdom (UK) is a constitutional monarchy where the Head of State is currently the Queen (part of the monarch) rather than the president. The roles, functions, and power are considered via convention, among them being that the monarch should be neutral politically (Bodleian Libraries 2021). The UK has three legal systems for England and Wales, Scotland, and Northern Ireland (Rab 2021). The former two nations use the common law system combining the approval of legislation by parliament, which includes the Monarch, House of Commons, and House of Lords, and the creation of precedents via case law (Rab 2021). The House of Commons is elected the population, with the Prime Minister being a traditional member of the House (Rab 2021). On the other hand, the judiciary is appointed to control the Court System and case law and is separate from the Parliament (Bodleian Libraries 2021). However, these systems are the UK law emanating from applicable laws to the UK, including its citizens. The UK law is summarized in the concept map highlighting the different types of laws governing the UK

description: We study four-dimensional N=2 supersymmetric pure-gauge (Seiberg-Witten) theory and its N=1 mass perturbation by using compactification S**1 x R**3. It is well known that on R**4 (or at large S**1) the perturbed theory realizes confinement through monopole or dyon condensation. At small S**1, we demonstrate that confinement is induced by a generalization of Polyakov's three-dimensional instanton mechanism to a locally four-dimensional theory - the magnetic bion mechanism - which also applies to a large class of nonsupersymmetric theories. Using a large- vs. small-L Poisson duality, we show that the two mechanisms of confinement, previously thought to be distinct, are in fact continuously connected.

description: Концепция нормальной бактериальной флоры организма человека является статистической концепцией, которая исходит из иммунной компетентности большинства населения. Однако, заметной тенденцией последних десятилетий является рост доли населения, имеющей скомпрометированную иммунную систему. Среди причин этого роста – старение, аутоиммунные процессы, врожденные, метаболические и дегенеративные заболевания, СПИД, усиление стрессового давления социальной среды, экологические факторы. Поэтому не удивительно, что на фоне широкого применения гормональной терапии, антимикробных средств и иммунодепрессантов, когда бактерии подвергаются действию веществ, взаимодействующих со структурными компонентами и метаболическими процессами, существенными для выживания микроба, in vivo возникают плеоморфные, мутантные и дремлющие бактериальные популяции.

description: Corporate social responsibility is a self-equipped business approach that helps an organization be socially responsible to its stakeholders and the overall public. Through the practice of CSR, companies are conscious and aware of the impacts they have on all aspects of society, including economic, social, and environmental (Goel and Ramanathan, 2014, p. 51). A case study scenario, in this case, is of StanBed Tours Ky, the impact of CSR on consumer loyalty, stating that the increase of CSR has resulted in the society's satisfaction with the business (Bediako, 2017, p. 1). CSR influences the people affected by it in various intensities and means. Such as, employees, who are part of the major stakeholders, are significantly affected by the organization's corporate social responsibility activities in marketing, which shape their logic, inspiration and lead to deeper commitments to achieving organizational goals and strategic plans (Makasi et al., 2014, p. 2600). Additionally, CSR investments in marketing significantly impact external shareholders such as consumers and the organization's image (Kaman, 2015, p. 7). CSR activities carried out by StanBed include tree planting exercises to mitigate carbon dioxide emissions resulting from flying airplanes, voluntary beach cleaning services to protect marine life, and providing educational services to children in the community of tours.

description: Because of globalisation's intense change and competition pressure, businesses are driving from the company's dimension of individual management to collaborative cooperation approaches aided by the anticipated business strategy. A business strategy is a decision or action of a business or organisation to attract customers and achieve the organisation's objective. These strategies are the master plan for securing a competitive position of the firm market area of the competitors. Through business strategies, organisations will carry their business operations and fulfill the customers' desires and demands. Multination organisations and firms establishing subsidiaries and business entities in international markets or foreign countries must adopt different strategies during the integration process. The macro-economic and intercultural factors are the epicenter for change and must be considered in complex ventures. In the modern competitive market, multinational firms must collaborate and communicate with the partners, suppliers and customers through a complicated and temporary product supply chain. Business strategies involve complex processes requiring information on the diverse sources that need simultaneous changes by the managers of entrepreneurs. I this report, I choose Tesla Inc or Tesla Motors to explore the key strategies they have anticipated to inherit the global motor vehicle sector within the past few decades. The organisation was founded in 2003 by a group of various engineers. Tesla Motors deal in the automotive industry and has transformed its services to the global society.

description: The construct of Leadership entails the process of influencing other people to accomplish specific objectives. However, like love, the construct of Leadership is a universal desire that is virtually difficult to define explicitly (Klingborg, Moore and Varea-Hammond, 2006, p.280). It is characterised by the idea of an individual charisma capable of recruiting followers towards his or her path, promoting team-based problem-solving. Conversely, the concept of Leadership is based on many factors such as; "leaders are made not born", "he was a leader since he was a kid" and "if you have the will power, you can become an effective leader" (Klingborg, Moore and Varea-Hammond, 2006, p.280). However, scholars and organisations tend to focus on Leadership and how leaders impact an organisation. The leadership process entails how an individual influences other(s) to achieve a common goal or mission.

description: In their different ownership structures, business enterprises pursue different strategies towards accomplishing their owners’ needs and interests. At the heart of these accomplishments is the generation of sufficient financial returns to cover obligations as they become due and residual incomes for the owners. It is doubtless that without a grip of financial stability, the survivability of for-profit organizations becomes bleak. Financial management plays and instrumental role in this case. The generation of sufficient information for decision making for the business and investors alike is integrally critical in shaping the progression of the business enterprise. While businesses provide financial statements according to prevailing laws and accounting standards to the public for their consumption in decision making, they are further needed to be accountable to them regarding their performance and investors’ engagements, especially considering that investors are foundational sources of capital for organizational operations.

description: Ejecta knot flickering, ablation tails, and fragmentation are expected signatures associated with the gradual dissolution of high-velocity supernova (SN) ejecta caused by their passage through an inhomogeneous circumstellar or interstellar medium. Such phenomena mark the initial stages of the gradual merger of SN ejecta with and the enrichment of the surrounding interstellar medium. Here we report on an investigation of this process through changes in the optical flux and morphology of several high-velocity ejecta knots located in the outskirts of the young core-collapse SN remnant Cassiopeia A using {\sl Hubble Space Telescope} images. Examination of WFPC2 F675W and combined ACS F625W + F775W images taken between June 1999 and December 2004 of several dozen debris fragments in the remnant's northeast ejecta stream and along the remnant's eastern limb reveal substantial emission variations ('flickering') over time scales as short as nine months. Such widespread and rapid variability indicates knot scale lengths ~ 10^15 cm and a highly inhomogeneous surrounding medium. We also identify a small percentage of ejecta knots located all around the remnant's outer periphery which show trailing emissions typically 0.2" to 0.7" in length aligned along the knot's direction of motion suggestive of knot ablation tails. We discuss the nature of these trailing emissions as they pertain to ablation cooling, knot disruption and fragmentation, and draw comparisons to the emission "strings" seen in eta Car. Finally, we identify several tight clusters of small ejecta knots which resemble models of shock induced fragmentation of larger SN ejecta knots caused by a high-velocity interaction with a lower density ambient medium.

description: Logical entropy gives a measure, in the sense of measure theory, of the distinctions of a given partition of a set, an idea that can be naturally generalized to classical probability distributions. Here, we analyze how fundamental concepts of this entropy and other related definitions can be applied to the study of quantum systems, leading to the introduction of the quantum logical entropy. Moreover, we prove several properties of this entropy for generic density matrices that may be relevant to various areas of quantum mechanics and quantum information. Furthermore, we extend the notion of quantum logical entropy to post-selected systems.

description: Accounting is a fundamental aspect of business operations because it records transactions through which businesses achieve and retain profitability. Recoding transactions is an important aspect of business because the primary goal of businesses is to maximise profitability (Tirole, 2010). Accounting lays the groundwork to manage the income, expenses, assets and cash flow of the firm, all of which are pivotal to the financial health of the business regardless of its size. This report discusses different accounting principles in practice. The first task utilises the double-entry method to record the transactions of the business in ledgers using the double-entry method. This task also includes the formulation of a trial balance using the balance off rule and illustrates to which final account each trial balance entry is attributable. The second task involves the creation of final accounts for different businesses. The legal implications of varying business structures differ, so their financial statements are different. This task also includes a discussion of the properties, purposes, and structures of different financial statements. The third task addresses bank reconciliation. Bank reconciliation resolves any discordance between the records of the business and its bank statement. The gist of the fourth task is the use of control accounts. Control accounts summarise ledger balances to ensure a match between those accounts and the accounts in the ledger of each account.

description: Organisations may either belong to the private sector or the public sector. When they are in the private sector, they can be large, small or medium-sized depending on the annual income and the number of workers they hire. Global organisations are developing rapidly because of the need to tap into new markets and production locations. Under the organisational structure, the organisation selected was Nike. It has several functional units whose activities are interrelated. For instance, human resource units ensure that the right personnel for finance or marketing are recruited and promoted. The emergence of new markets in BRIC and the digital revolution are highly relevant to external factors that affect the organisation. As a response, Nike has used social media and the digital revolution to reach customers directly. It, however, needs to take on new markets and products to remain in business.

description: We investigate the electromagnetic form factors of the Delta and the Omega baryons within the Poincare-covariant framework of Dyson-Schwinger and Bethe-Salpeter equations. The three-quark core contributions of the form factors are evaluated by employing a quark-diquark approximation. We use a consistent setup for the quark-gluon dressing, the quark-quark bound-state kernel and the quark-photon interaction. Our predictions for the multipole form factors are compatible with available experimental data and quark-model estimates. The current-quark mass evolution of the static electromagnetic properties agrees with results provided by lattice calculations.

description: We investigate finite-size effects on chiral symmetry breaking in a four-fermion interaction model at a finite temperature and a chemical potential. Applying the imaginary time formalism, the thermal quantum field theory is constructed on an $S^1$ in the imaginary time direction. In this paper, the finite-size effect is introduced by a compact $S^1$ spatial direction with a $\mathrm{U}(1)$-valued boundary condition. Thus, we study the model on a $\mathbb{R}^{D-2} \times S^1 \times S^1$ torus. Phase diagrams are obtained by evaluating the local minima of the effective potential in the leading order of the $1/N$ expansion. From the grand potential, we calculate the particle number density and the pressure, then we illustrate the correspondence with the phase structure. We obtain a stable size for which the sign of the pressure flips from negative to positive as the size decreases. Furthermore, the finite chemical potential expands the parameter range that the stable size exists.

description: This new 1:50,000 geological map covers 830 km2 between the southern shoreline of Manukau Harbour and the lower Waikato River. The area, which includes Pukekohe, Waiuku, Pōkeno, and Papakura townships. Basement rocks (Austral Superprovince) beneath the map area consist of three fault-bounded, meta-sedimentary and meta-igneous terranes of Permian to Early Cretaceous age, although it is only Triassic–Jurassic ‘greywacke’ rocks of Waipapa Composite Terrane that crop out. An overlying succession of cover strata (Zealandia Megasequence), in places >1 km thick, consists of Late Eocene–Early Miocene non- to deep-marine sedimentary rocks (Te Kuiti, Waitematā, and Waitākere groups) unconformably overlain by Pliocene to Holocene terrestrial and shallow-marine sedimentary strata (Tauranga Group). Intra-plate effusive and explosive basaltic volcanism of Early to Middle Pleistocene age (South Auckland Volcanic Field) underpins the distinctive landscape within the southern parts of the map area. Distal airfall and pyroclastic flow deposits from North Island’s Central Volcanic Region have further modified the region’s landscape.

description: Let G be a finite graph with the non-k-order property (essentially, a uniform finite bound on the size of an induced sub-half-graph). A major result of the paper applies model-theoretic arguments to obtain a stronger version of Szemerédi's regularity lemma for such graphs, Theorem 5.18, in which there are no irregular pairs, the bounds are significantly improved, and each component satisfies an indivisibility condition. Motivation for this work comes from a coincidence of model-theoretic and graph-theoretic ideas. Namely, it was known that the "irregular pairs" in the statement of Szemerédi's regularity lemma cannot be eliminated, due to the counterexample of half-graphs. The results of this paper show in what sense this counterexample is the only essential difficulty. The proof is largely model-theoretic (though written to be accessible to finite combinatorialists): arbitrarily large half-graphs coincide with model-theoretic instability, so in their absence, structure theorems and technology from stability theory apply. In addition to the theorem quoted, we give several other regularity lemmas with different advantages, in which the indivisibility condition on the components is improved (at the expense of letting the number of components grow with |G|) and extend some of these results to the larger class of graphs without the independence property.

description: Using 3D-MHD Eulerian-grid numerical simulations, we study the formation and evolution of rising magnetic towers propagating into an ambient medium. The towers are generated from a localized injection of pure magnetic energy. No rotation is imposed on the plasma. We compare the evolution of a radiatively cooling tower with an adiabatic one, and find that both bend due to pinch instabilities. Collimation is stronger in the radiative cooling case; the adiabatic tower tends to expand radially. Structural similarities are found between these towers and the millimeter scale magnetic towers produced in laboratory experiments.

Based on the magnetotransport properties of Mn doped Ge, we argue that the hole concentration is a decisive parameter in establishing carrier-mediated ferromagnetism in magnetic Ge.

description: The American woman's college is not yet sixty-five years old. The establishment of Vassar College in 1865 marks the first real effort to develop institutions of higher education for women alone. During these sixty-five years profound social changes have taken place in American life. These changes have affected, especially, the world of women. Due to the developments of modern science and the spirit of American democracy, the entire industrial, economic, political and social world for women has been revolutionized since Vassar College opened its doors. As a result of this revolution, the industrial and professional life of American women, as it centers around the field of gainful occupations, has likewise changed completely. Especially is this true during the past four decades, since 1890, as is shown in the reports of the United States Census Bureau and the reports of the United States Department of Labor. It is evident, therefore, if education is to carry out its generally expressed purpose of preparation for life, or, in a democracy, preparation for citizenship, that the objectives of the educational institutions of America, during these sixty-five years of social change, have constantly needed reexamination and re-statement. And if this is true for education as a whole, it is especially true in regard to the education of women. The purpose of this investigation is, therefore, to study the world of American women as it exists today, and to examine the objectives of colleges for women, with the view of determining what place, among these objectives, should be given to vocational training. If we are adequately to prepare the students of these colleges to do their full duty as American citizens, such an investigation should be helpful

description: Обучение вопросам питания. Поликлиники могут предлагать программы обучения правильному питанию для родителей и детей, уделяя особое внимание важности сбалансированного питания. Они могут дать рекомендации по размеру порций, соответствующему возрасту, включению фруктов и овощей, а также ограничению употребления сладких и обработанных пищевых продуктов. Нас сейчас не может удовлетворить то понимание профилактики, которое включает в себя только предупреждение развития заболевания. Проблемы семьи и здорового образа жизни остаются крайне актуальными для нашей страны. Острота демографической ситуации, связанная в основном с кардинальными социально-экономическими переменами последних десятилетий, напрямую затрагивает жизненные интересы всего российского общества.

description: In various applications, the effect of errors in gradient-based iterations is of particular importance when seeking saddle points of the Lagrangian function associated with constrained convex optimization problems. Of particular interest here are problems arising in power control applications, where network utility is maximized subject to minimum signal-to-interference-plus-noise ratio (SINR) constraints, maximum interference constraints, maximum received power constraints, or simultaneous minimum and maximum SINR constraints. Especially when the gradient iterations are executed in a disributed fashion, imperfect exchanges among the link nodes may result in erroneous gradient vectors. In order to assess and cope with such errors, two running averages (ergodic sequences) are formed from the iterates generated by the perturbed saddle point method, each with complementary strengths. Under the assumptions of problem convexity and error boundedness, bounds on the constraint violation and the suboptimality per iteration index are derived. The two types of running averages are tested on a spectrum sharing problem with minimum and maximum SINR constraints, as well as maximum interference constraints.

description: We use the "tridiagonal representation approach" to solve the time-independent Schrödinger equation for the bound states of generalized versions of the trigonometric and hyperbolic Pöschl-Teller potentials. These new solvable potentials do not belong to the conventional class of exactly solvable problems. The solutions are finite series of square integrable functions written in terms of the Jacobi polynomial.

description: We use molecular dynamics with a first-principles based shell model potential to study pyroelec- tricity in lithium niobate. We find that the primary pyroelectric effect is dominant, and pyroelec- tricity can be understood simply from the anharmonic change in crystal structure with temperature and the Born effective charges on the ions. This opens a new experimental route to studying py- roelectricity, as candidate pyroelectric materials can be studied with X-ray diffraction as a function of temperature in conjunction with theoretical effective charges. We also predict an appreciable pressure effect on pyroelectricity, which could be used to optimize materials pyroelectricity, and the converse electrocaloric effect, peak as Tc is approached.

description: Reaction-diffusion systems with reversible reactions generically display power-law relaxation towards chemical equilibrium. In this work we investigate through numerical simulations aging processes that characterize the non-equilibrium relaxation. Studying a model which excludes multiple occupancy of a site, we find that the scaling behavior of the two-time correlation and response functions are similar to that discovered previously in an exactly solvable version with no restrictions on the occupation numbers. Especially, we find that the scaling of the response depends on whether the perturbation conserves a certain quantity or not. Our results point to a high degree of universality in relaxation processes taking place in diffusion-limited systems with reversible reactions.

Gravitational wave background from sub-luminous GRBs: prospects for second and third generation detectors

description: We assess the detection prospects of a gravitational wave background associated with sub-luminous gamma-ray bursts (SL-GRBs). We assume that the central engines of a significant proportion of these bursts are provided by newly born magnetars and consider two plausible GW emission mechanisms. Firstly, the deformation-induced triaxial GW emission from a newly born magnetar. Secondly, the onset of a secular bar-mode instability, associated with the long lived plateau observed in the X-ray afterglows of many gamma-ray bursts (Corsi & Meszaros 2009a). With regards to detectability, we find that the onset of a secular instability is the most optimistic scenario: under the hypothesis that SL-GRBs associated with secularly unstable magnetars occur at a rate of (48; 80)Gpc^{-3}yr^{-1} or greater, cross-correlation of data from two Einstein Telescopes (ETs) could detect the GW background associated to this signal with a signal-to-noise ratio of 3 or greater after 1 year of observation. Assuming neutron star spindown results purely from triaxial GW emissions, we find that rates of around (130;350)Gpc^{-3}yr^{-1} will be required by ET to detect the resulting GW background. We show that a background signal from secular instabilities could potentially mask a primordial GW background signal in the frequency range where ET is most sen- sitive. Finally, we show how accounting for cosmic metallicity evolution can increase the predicted signal-to-noise ratio for background signals associated with SL-GRBs.

description: It has been previously shown that calculation of renormalization group (RG) functions of the scalar ϕ^4 theory reduces to the analysis of thermodynamic properties of the Ising model. Using high-temperature expansions for the latter, RG functions of four-dimensional theory can be calculated for arbitrary coupling constant g with an accuracy 10^{-4} for the Gell-Mann - Low function β(g) and an accuracy 10^{-3} - 10^{-2} for anomalous dimensions. Expansions of RG functions up to the 13th order in g^{-1/2} are obtained.

description: Not long after embarking on her PhD, data scientist Paola Chiara Masuzzo began to feel she was being coaxed into writing research papers primarily for one self-serving purpose: publishing in respected journals to increase the prestige of others. Fed up with this academic culture and the exploitative publishing industry, she decided to go rogue - and has since rediscovered how much she loves good science.

description: Magnesium and its alloys have been in the focus of investigation as a material for temporary implants because of several material properties. First of
 all, magnesium is known to be biodegradable, biocompatible and non-toxic. In addition, the density of magnesium is close to that of human bone.
 One of the main obstacle for application of Mg alloys is their low corrosion resistance, especially in the environment containing the high
 concentration of chloride ions.
 In this work, the corrosion resistance of composite chitosan – based coatings deposited on Mg20Zn substrate was investigated. The following types
 of coatings were deposited on Mg20Zn alloy: chitosan, chitosan containing silica glass and Na2SiO3. The chitosan coatings were deposited on the
 substrate by means of spin coater. The surface morphology and composition of the composite chitosan coatings were characterized by Fourier
 transformed infrared spectroscopy (FTIR), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy
 (SEM) with energy-dispersive spectroscopy (EDS). The corrosion tests has been performed in the Hank’s solution at 37 °C. The electrochemical
 performance of coated magnesium alloy was evaluated by linear sweep voltamperometry (LSV) and electrochemical impedance spectroscopy. The
 corrosion tests have revealed that the chitosan coatings improve the corrosion resistance of magnesium alloys in the Hank’s solution. The highest
 corrosion resistance of Mg alloy was found when chitosan coatings were modified by addition of silicon glass and Na2SiO3.
