description: We solve the group classification problem for the $2+1$ generalized quantum Zakharov-Kuznetsov equation. Particularly we consider the generalized equation $u_{t}+f\left( u\right) u_{z}+u_{zzz}+u_{xxz}=0$, and the time-dependent Zakharov-Kuznetsov equation $u_{t}+δ\left( t\right) uu_{z}+λ\left( t\right) u_{zzz}+\varepsilon \left( t\right) u_{xxz}=0$% . Function $f\left( u\right) $ and $δ\left( t\right) ,~λ\left( t\right) $,~$\varepsilon \left( t\right) $ are determine in order the equations to admit additional Lie symmetries.\ Finally, we apply the Lie invariants to find similarity solutions for the generalized quantum Zakharov-Kuznetsov equation.

description: Philosopher and aesthetician Arto Haapala (2005) claims that the routine gives us a feeling of homeyness and control. Brushing teeth, dressing or cleaning are tasks that we perform almost automatically every day and in their repetitiveness we find a balance against the unpredictability of reality outside our homes. But what if daily routine becomes a permanent condition? If the ruptures that disrupt it go away? The global pandemic has exposed us to a new model of existence. By accelerating the extraction of daily routine’s monotonous cycle, it disrupted its basic function - to keep our lives within the limits of (apparent) normalcy. One way to restore the status of support to everyday rituals is to place them in an aesthetic dimension. For example, by making the dusting a performative act. What happens to a routine when we “infect” it with the language of a dance performance? In my paper, I will address the question of how the pandemic changed the perception of everyday rituals and how the dance or performative movement can be one of the effective tools to bring the safety and familiarity back to the routine.

description: Sudden cardiac death and ventricular arrhythmias are a global health issue. Recently, a new guideline for the management of ventricular arrhythmias and prevention of sudden cardiac death has been published by the European Society of Cardiology that serves as an update to the 2015 guideline on this topic. This review focuses on 10 novel key aspects of the current guideline: As new aspects, public basic life support and access to defibrillators are guideline topics. Recommendations for the diagnostic evaluation of patients with ventricular arrhythmias are structured according to frequently encountered clinical scenarios. Management of electrical storm has become a new focus. In addition, genetic testing and cardiac magnetic resonance imaging significantly gained relevance for both diagnostic evaluation and risk stratification. New algorithms for antiarrhythmic drug therapy aim at improving safe drug use. The new recommendations reflect increasing relevance of catheter ablation of ventricular arrhythmias, especially in patients without structural heart disease or stable coronary artery disease with only mildly impaired ejection fraction and haemodynamically tolerated ventricular tachycardias. Regarding sudden cardiac death risk stratification, risk calculators for laminopathies, and long QT syndrome are now considered besides the already established risk calculator for hypertrophic cardiomyopathy. Generally, "new" risk markers beyond left ventricular ejection fraction are increasingly considered for recommendations on primary preventive implantable cardioverter defibrillator therapy. Furthermore, new recommendations for diagnosis of Brugada syndrome and management of primary electrical disease have been included. With many comprehensive flowcharts and practical algorithms, the new guideline takes a step towards a user-oriented reference book.

Clastic sediment sources and suspended sediment yield in a Coast Mountain watershed, British Columbia
Creators: name: Hart, Jackson Sanford
Publisher: name: University of British Columbia
Year: 2010

description: This dissertation investigates the clastic sediment sources and suspended sediment yields of clear-cut and undisturbed areas of a glacially- -modified, 33 km² watershed in the southern Coast Mountains of British Columbia. Surficial materials were mapped and the character of sediment movement interpreted by morphologic evidence. Basin sediment yields through snowmelt, summer low flow and fall storm periods were related to the magnitude of precipitation inputs, storage changes of snow and the availability of clastic sediment to the channel system. In the undisturbed area sediment activated along steep tributary streams of the till-mantled valley walls below treeline was considered most important to basin scale yield. In the alpine zone mass wastage activity is widespread yet effects mainly a redistribution of materials on slopes; sediment supply to the fluvial system is limited by the extensive presence of coarse materials and the lower drainage density. Snowmelt period sediment export exceeded that during summer low flow and October storm periods; however, approximately 60 percent of the total sediment yield observed took place during a November rain-on-snow event of an estimated 10 year recurrence interval. During the October storm period, when sediment yields from the forested and clear-cut slopes could be isolated, sediment removal from the clear-cut slope was greater by approximately eight times and this accelerated erosion was attributed almost entirely to road effects.

description: We prove a strengthened version of a theorem of Lionel Schwartz that says that certain modules over the Steenrod algebra cannot be the mod 2 cohomology of a space. What is most interesting is our method, which replaces his iterated use of the Eilenberg--Moore spectral sequence by a single use of the spectral sequence converging to the mod 2 cohomology of Omega^nX obtained from the Goodwillie tower for the suspension spectrum of Omega^nX. Much of the paper develops basic properties of this spectral sequence.

The presentation, by IEEE Smart Grid Expert,  Imre Gyuk, will discuss multi-megawatt applications of a variety of energy storage technologies. Major storage facilities recently constructedin Texas, California, Pennsylvania, and New Mexico under the ARRA stimulus program will be presented. As major players begin deploying increasingly more substantial storage projects, operators are recognizing their value for ancillary services. Storage will make renewables dispatchable and enable deeper penetration. It will also make the grid more resilient, improve asset utilization, and prevent outages.
A record-driven growth process

Year: 2008
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: We introduce a novel stochastic growth process, the record-driven growth process, which originates from the analysis of a class of growing networks in a universal limiting regime. Nodes are added one by one to a network, each node possessing a quality. The new incoming node connects to the preexisting node with best quality, that is, with record value for the quality. The emergent structure is that of a growing network, where groups are formed around record nodes (nodes endowed with the best intrinsic qualities). Special emphasis is put on the statistics of leaders (nodes whose degrees are the largest). The asymptotic probability for a node to be a leader is equal to the Golomb-Dickman constant omega=0.624329... which arises in problems of combinatorical nature. This outcome solves the problem of the determination of the record breaking rate for the sequence of correlated inter-record intervals. The process exhibits temporal self-similarity in the late-time regime. Connections with the statistics of the cycles of random permutations, the statistical properties of randomly broken intervals, and the Kesten variable are given.

description: We propose a novel approach of wet electrospinning to yield fiber-reinforced polymer ceramic composites, where a reactive ceramic precursor gel is used as a collector. We illustrate our approach by generating polyethylene oxide (PEO) fibers in a potassium silicate gel; the gel is later activated using metakaolin to yield a ceramic-0.5 wt% PEO fiber composite. An increase of 29% and 22% is recorded for the fabricated polymer ceramic composites in terms of indentation modulus and indentation hardness respectively. Our initial findings demonstrate the process viability and might lead to a potentially scalable manufacturing approach for fiber-reinforced polymer ceramic composites.

title: Premiumerwerb internationaler Investoren für Immobilien in deutschen Städten

Publisher: name: UNSPECIFIED

description: Umfangreiche internationale Transaktionen am Investmentmarkt für Immobilien des letzten Jahrzehnts werfen die grundlegende Frage auf, ob sich diese von nationalen unterscheiden. Als methodische Entwicklung soll mittels Propensity Score-Matching der Einfluss von verschiedenen Transaktions-charakteristika in den Stichproben begrenzt werden, die nicht mit den von ausländischen Investoren gekauften und verkauften Transaktionen vergleichbar sind, sodass das Problem der Selektionsverzerrung gelöst wird.
Für eine deutsche Stichprobe mit Daten zu knapp 2.400 gewerblichen Immobilientransaktionen von Büroimmobilien in den sieben A-Lagen werden in der ersten Studie sowohl Auswirkungen auf Kauf- als auch auf Verkaufspreise analysiert. Dabei wird aufgezeigt, dass internationale Investoren im Vergleich zu ähnlichen Immobilien, die von nationalen Investoren gekauft und verkauft werden, mit einem signifikanten Abschlag von ca. 14,7% verkaufen, während ein signifikanter Preisaufschlag internationaler Käufer dann realisiert wird, wenn auf der Verkäuferseite ein nationaler Investor vertreten ist. Dabei beträgt das gezahlte Premium ca. 13,1%. Nationale Verkäufer erzielen damit bessere Preise, wenn auf der Käuferseite ein internationaler Investor vertreten ist.
Die zweite Studie zeigt, dass ein Premium von ausländischen Investoren in Höhe von ca. 22,4% beim Ankauf gezahlt wird. Darüber hinaus kann durch Tests auf Asymmetrie aufgezeigt werden, dass ausländische Investoren ein höheres Premium von ca. 30,3% zahlen, wenn auf der Verkäuferseite inländische Investoren vertreten sind. Weiterführende Analysen auf nicht gemessene Qualitätsmerkmale zeigen, dass es unbeobachtete und positive, preisliche Eigenschaften bei ausländischen Transaktionen gibt.
In der dritten Studie wird aufgezeigt, dass internationale Investoren im Vergleich zu ähnlichen Immobilien, die von nationalen Investoren gekauft und verkauft werden, mit einem signifikanten Premium von ca. 31% kaufen. Das Premium ist nahezu identisch mit ca. 30%, wenn auf der Verkaufsseite ein nationaler Investor vertreten ist. Weiterführende Tests auf nicht gemessene Qualitätsmerkmale deuten darauf hin, dass es unbeobachtete preisliche Eigenschaften im Zusammenhang mit ausländischen Transaktionen gibt, wo sowohl Käufer als auch Verkäufer ausländischer Herkunft sind.
title:  Speculating Everyday Beauty

description: Everyday aesthetics inter alia claims: Also outside of art, there is beauty. The existence of such extra-artistic beauty is taken as a given in this branch of aesthetic research; yet the issue it faces is of a methodological kind: How would it be possible to research ordinary beauties without turning them into extraordinary beauties and thus re-aligning them to art? The present paper proposes the method of speculation as a possible solution. Speculation is argued to be of aid for everyday aesthetics, because taking a speculative stance on reality means to not intervene in it, but to rather take a step back and respectfully narrate the withdrawing from our human perception that certain aspects of reality undertake. As such, speculation is a possibility to master the paradox faced by everyday aesthetics, which consists in engaging without intruding on beauties hiding within the everyday, and hence of preserving while and whilst researching them.

title: Viral Etiology of Central Nervous System Infections and Community-Acquired Sepsis in Southeast Asia: Unravelling the Unknown
Creators: name: Nguyen, To Anh
Publisher: name: The Open University
Year: 2021

description: My PhD research consists of a series of studies on the application of metagenomic next-generation sequencing (mNGS) to search for viral etiology in patients presenting with community-acquired sepsis or central nervous system (CNS) infections. I first developed a mNGS workflow for the sensitive detection of a broad range of viruses in clinical samples (Chapter 2). I then used this optimized method to search for viruses in 665 patients presenting with community-acquired sepsis of unknown origin enrolled in an observational study across Thailand and Vietnam in 2013-2015. While the mNGS analysis revealed significant insights into the epidemiology of sepsis in both countries, the analysis also led to the first detection of a recently discovered flavivirus - human pegivirus 2 (HPgV-2) - in a serum sample of a Vietnamese patient co-infected with HIV and HCV. This represents the first detection of HPgV-2 in Vietnam. Therefore, I conducted further research to unravel its epidemiology in Vietnam (Chapter 4). In Chapter 5, I used mNGS to analyze 204 cerebrospinal fluid (CSF) from patients with CNS infections of unknown origin enrolled from hospitals across central and southern Vietnam in 2012-2016. Enteroviruses were the most common viruses detected, especially in children and young adults. To inform future research directions, I conducted a pilot of 66 consecutive CSF samples collected from patients presenting with CNS infections admitted to the Hospital for Tropical Diseases in Ho Chi Minh City, Vietnam (Chapter 6). mNGS accurately detected a wide range of pathogens that were also detected by routine diagnostic methods, but also increased the diagnostic yield from 22.7% (15/66) to 34.8% (23/66) (Chapter 6). Finally, in Chapter 7, I provide an overview about my research findings, and propose some future directions based on the main findings obtained during my PhD research.

description: In this work, a new version of KNOSOS is presented. KNOSOS is a low-collisionality radially-local, bounce-averaged neoclassical code that is extremely fast, and at the same time, includes physical effects often neglected by more standard codes: the component of the magnetic drift that is tangent to the flux-surface and the variation of the electrostatic potential on the flux-surface. An earlier version of the code could only describe configurations that were sufficiently optimized with respect to neoclassical transport. KNOSOS can now be applied to any large aspect ratio stellarator, and its performance is demonstrated by means of detailed simulations in the configuration space of Wendelstein 7-X.

description: We update the theoretical predictions for direct Y(nS) hadroproduction in the framework of NRQCD. We show that the next-to-leading order corrections in alpha_s to the color-singlet transition significantly raise the differential cross section at high pT and substantially affect the polarization of the Upsilon. Motivated by the remaining gap between the NLO yield and the cross section measurements at the Tevatron, we evaluate the leading part of the alpha_s^5 contributions, namely those coming from Y(nS) associated with three light partons. The differential color-singlet cross section at alpha_s^5 is in substantial agreement with the data, so that there is no evidence for the need of color-octet contributions. Furthermore, we find that the polarization of the Y(nS) is longitudinal. We also present our predictions for Y(nS) production at the LHC.

This webinar is based on an earlier SmartGrid e-newsletter article, “Active Damping With Energy Storage to Improve Power System Frequency Stability”, http://bit.ly/IEEESG_Jan2020eNews . This earlier article outlined how appropriately designed energy storage (ES) systems can offset the negative power system impacts of reduced inertia (H, MW-s), as traditional rotating machines are offset by inverter based resources including PV.
In this webinar, the authors focus on two specific areas, 1) underlying control design concept for using ES with advanced power electronics with advanced grid sensing (e.g. PMU’s) to damp power system oscillations, 2) examples of early energy storage systems that have demonstrated that appropriately designed ES systems can and have supported power system frequency stability.

Slides for Webinar: Part 1 - Expanding DER Hosting Capacity: Processes, Features, and Methods
This presentation addresses topics covering utilities new practices to reduce economic barriers to the expansion of renewable DERs. Increasing DER Hosting Capacity not only can enable more market participants, but primarily improves the economic feasibility of many projects. Traditional utility practices are very restrictive on how DERs can operate. Forms of operational control that were not previously adopted, such as DER voltage control, have recently been considered and accepted by utilities to fulfill modern societal mandates. Another essential feature in the interconnection of DERs is the ability to detect operation under islanded condition. International standards have strict requirements for detection and extinction of islanding conditions, resulting in requirements that may preclude renewable DER projects to become financially viable. The acceptance of inverter native active anti-islanding schemes is a potential low-cost solution but represents a new paradigm for electric utilities. Similarly, employing out-of-the-box solutions to improve performance grounding and protection coordination are needed to streamline interconnection.

Part 1: Multi-Energy Systems (MES), in which multiple energy carriers are integrated and optimally operated, are key assets to enable low-carbon energy systems. Multi-carrier integration of distributed energy resources via different energy networks generates the so-called distributed MES (DMES). This webinar presents foundational concepts to characterize, model, optimise, and visualise the flexibility that could be provided to the electricity grid by DMES, including the role of integrated energy networks (e.g., electricity, heat and gas) in enabling or constraining power system flexibility. Several examples will be presented with illustrative case studies on current and future DMES practical applications, including technologies and concepts such as: combined heat and power (CHP); combined cooling, heat, and power (CCHP); electric heat pumps, electric boilers, and hybrid (electricity-gas) boilers and heat pumps; power-to- hydrogen and power-to-gas; integrated electricity-hydrogen virtual power plants; power-to-heat; building-to-grid flexibility; virtual energy storage; community energy systems; etc.

Part 2: Non Frequency-related Ancillary Services, Testing Procedures of new DRES converters, Identification of Obstacles and Suggestions for lifting them

The high proliferation of inverter-interfaced Distributed Renewable Energy Sources (DRES) at distribution grid level will gradually replace the conventional fuel-driven synchronous generators (SGs) at transmission system level. The inverter-interfaced DRES are mostly driven by variable-output RES such as PV or wind plants and for this reason are considered as non-dispatchable. There are DRES employing SGs directly connected to the grid which are mostly driven by biomass or small-hydro units, thereby considered as dispatchable. Although non-dispatchable, the inverter-interfaced DRES are highly controllable, thus able to provide a number of new services. DRES, particularly the inverter-interfaced ones, must urgently adopt a new more active role in the electricity networks by providing Part 1: Ancillary Services (AS) similarly to the conventional SGs and even new ones within the distribution grids in order to keep the system stability and robustness. Such AS include: inertial response, active power ramp rate control, operation in frequency sensitive mode, voltage regulation, contribution to fault clearing and harmonic mitigation. This webinar will provide suggestions on (i) how to control the DRES inverters, so that they behave as controllable SGs able to provide the aforementioned AS in a unified way; (ii) methods to aggregate frequency related AS to be offered to the transmission system; (iii) methods on the measurement and quantification of various AS, so that they are transformed from system support functions into tradable AS; (iv) methods for testing the DRES inverters with respect to the new AS. The webinar will also present the obstacles posed by current grid codes, standards or market regulations for the introduction of the new AS and provide suggestions on lifting those obstacles. It is noted that batteries, although not a conventional type of RES, are included in this webinar, since they can provide a number of the aforementioned AS either by themselves or in combination with the non-dispatchable DRES.

The phenomenological perspective seems especially interested in the most detailed and full presentation of human experience complete with atmosphere and value judgments and thus also in portraying the emotional reactions towards the world-as-experienced. The paper also focuses on the category of listening-in understood as an attentive, open, and engaged relation to the world.

Although non-dispatchable, the inverter-interfaced DRES are highly controllable, thus able to provide a number of new services. DRES, particularly the inverter-interfaced ones, must urgently adopt a new more active role in the electricity networks by providing Part 1: Ancillary Services (AS) similarly to the conventional SGs and even new ones within the distribution grids in order to keep the system stability and robustness. Such AS include: inertial response, active power ramp rate control, operation in frequency sensitive mode, voltage regulation, contribution to fault clearing and harmonic mitigation. This webinar will provide suggestions on (i) how to control the DRES inverters, so that they behave as controllable SGs able to provide the aforementioned AS in a unified way; (ii) methods to aggregate frequency related AS to be offered to the transmission system; (iii) methods on the measurement and quantification of various AS, so that they are transformed from system support functions into tradable AS; (iv) methods for testing the DRES inverters with respect to the new AS. The webinar will also present the obstacles posed by current grid codes, standards or market regulations for the introduction of the new AS and provide suggestions on lifting those obstacles. It is noted that batteries, although not a conventional type of RES, are included in this webinar, since they can provide a number of the aforementioned AS either by themselves or in combination with the non-dispatchable DRES.

description: Encapsulation of human mesenchymal stem cells is a well explored technique for different applications. Herein, we fabricated microcapsules of commercial biocompatible hydrogel matrix encapsulated with hMSCs. Electro-spraying the hydrogel solution helped us achieve uniform sized capsules that could be translated into a suspension bioreactor culture for cell expansion. Evaluating the critical process parameters that directly influence the cell quality attributes, we optimized the conditions to maximize cell yield post bioreactor harvest, without compromising the cell functionality and phenotype. We achieved an expansion of 10x for certain conditions and cell passage number. Using fed-batch approach helped us eliminate a taxing step of media exchange, vertical wheel impeller homogeneously distributed the nutrients necessary for cell expansion. Finally, we performed genetic engineering of cell by co-encapsulation of viral particles inside the matrix. This helped us understand the potential of the system for future biomanufacturing of hMSC.

description: In this work we investigated correlations between the internal microstructure and sample size (lateral as well as thickness) of mesoscopic, tens of nanometer thick graphite (multigraphene) samples and the temperature $(T)$ and field $(B)$ dependence of their electrical resistivity $ρ(T,B)$. Low energy transmission electron microscopy reveals that the original highly oriented pyrolytic graphite material -- from which the multigraphene samples were obtained by exfoliation -- is composed of a stack of $\sim 50 $nm thick and micrometer long crystalline regions separated by interfaces running parallel to the graphene planes. We found a qualitative and quantitative change in the behavior of $ρ(T,B)$ upon thickness of the multigraphene samples, indicating that their internal microstructure is important.} {The overall results indicate that the metallic-like behavior of $ρ(T)$ at zero field measured for bulk graphite samples is not intrinsic of ideal graphite. The results suggest that the interfaces between crystalline regions may be responsible for the superconducting-like properties observed in graphite. Our transport measurements also show that reducing the sample lateral size as well as the length between voltage electrodes decreases the magnetoresistance, in agreement with recently published results. The magnetoresistance of the multigraphene samples shows a scaling of the form ($(R(B) - R(0))/R(0))/T^α= f(B/T)$ with a sample dependent exponent $α\sim 1$, which applies in the whole temperature 2 K $\le T \le 270$K and magnetic field range $B \le 8 $T.

Slides for Webinar: Electric Vehicles for Public Transportation in Smart Grids
The market for electric vehicles (EVs) has grown with each year, and EVs are considered to be a proper solution for the mitigation of urban pollution. However, it is well known that a massive introduction of EVs will lead to grid issues, so significant research has been performed in this area. However, a few research has been devoted to EVs for public transportation, such as taxis and buses. This webinar will focus on new trends, technologies, and challenges for integrating properly electric taxis and buses in power systems.
Dynamics of a vortex domain wall in a magnetic nanostrip: an application of the collective coordinate approach

description: The motion of a vortex domain wall in a ferromagnetic strip of submicron width under the influence of an external magnetic field exhibits three distinct dynamical regimes. In a viscous regime at low fields the wall moves rigidly with a velocity proportional to the field. Above a critical field the viscous motion breaks down giving way to oscillations accompanied by a slow drift of the wall. At still higher fields the drift velocity starts rising with the field again but with a much lower mobility dv/dH than in the viscous regime. To describe the dynamics of the wall we use the method of collective coordinates that focuses on soft modes of the system. By retaining two soft modes, parametrized by the coordinates of the vortex core, we obtain a simple description of the wall dynamics at low and intermediate applied fields that describes both the viscous and oscillatory regimes below and above the breakdown. The calculated dynamics agrees well with micromagnetic simulations at low and intermediate values of the driving field. In higher fields, additional modes become soft and the two-mode approximation is no longer sufficient. We explain some of the significant features of vortex domain wall motion in high fields through the inclusion of additional modes associated with the half-antivortices on the strip edge.

Slides for Webinar: Part 2: Flexibility provision from distributed multi-energy systems
Part 2: Multi-Energy Systems (MES), in which multiple energy carriers are integrated and optimally operated, are key assets to enable low-carbon energy systems. Multi-carrier integration of distributed energy resources via different energy networks generates the so-called distributed MES (DMES). This webinar presents foundational concepts to characterize, model, optimise, and visualise the flexibility that could be provided to the electricity grid by DMES, including the role of integrated energy networks (e.g., electricity, heat and gas) in enabling or constraining power system flexibility. Several examples will be presented with illustrative case studies on current and future DMES practical applications, including technologies and concepts such as: combined heat and power (CHP); combined cooling, heat, and power (CCHP); electric heat pumps, electric boilers, and hybrid (electricity-gas) boilers and heat pumps; power-to- hydrogen and power-to-gas; integrated electricity-hydrogen virtual power plants; power-to-heat; building-to-grid flexibility; virtual energy storage; community energy systems; etc.

description: An analysis of the residual-velocity field of OB associations within 3 kpc of the Sun has revealed periodic variations in the radial residual velocities along the Galactic radius vector with a typical scale length of lambda=2.0(+/-0.2) kpc and a mean amplitude of fR=7(+/-1) km/s. The fact that the radial residual velocities of almost all OB-associations in rich stellar-gas complexes are directed toward the Galactic center suggests that the solar neighborhood under consideration is within the corotation radius. The azimuthal-velocity field exhibits a distinct periodic pattern in the region 0

description: The deformation and crack initiation mechanisms were analyzed in a textured AZ31B-O Mg alloy subjected to fully-reversed, strain-controlled cyclic deformation along the rolling direction after 50 cycles (approximately 33% of the fatigue life). Distinct deformation bands corresponding to pyramidal slip or tensile twins were found in 538 grains out of 2100 grains. Slip trace analysis showed that 72.3% were pyramidal slip bands and 18.4% were twin boundaries. Both pyramidal slip and twinning was only found in 9.1% of the grains with deformation bands. Cracking was widespread after 50 cycles. Grain boundary cracks were found in approximately 15% of the small grains (< 20 $μ$m) and they were mainly associated with high angle grain boundaries (>40 degrees). Cracking was also found to occur by transgranular cracks parallel to the pyramidal slip bands or twin boundaries in large grains (>45 $μ$m). The majority (>60%) of these large grains presented transgranular cracks after 50 cycles.
