description: On the basis of a theoretical discussion about the concepts of leisure and media use, the article investigates how so-called ordinary people apply different media to disclose part of their leisure time and everyday life for public consumption not only in order to construct a personal identity formation, but also in order to commercialize the self. The interaction and everyday actions of participants in reality programmes on television and creators of Vlogs on YouTube are objects for observation and recording leisure behaviour with the intention to entertain and engage other people in their free time. There are two principal aspects of this: first, the functionality of the leisure time in the present media culture, in which performing and presenting the self in various situations become a serious matter for the reality star or Vlogger. Second, power and control of the performance are significant aspects of understanding this functionality, which furthermore involves a distinction regarding the specific affordances of television and YouTube as media platforms. The article’s theoretical fundament framework draws on Colin Campbell’s revision of Max Weber, and especially the notion of modern hedonism.

description: This paper presents an approach to provide strong assurance of the secure execution of distributed event-driven applications on shared infrastructures, while relying on a small Trusted Computing Base. We build upon and extend security primitives provided by Trusted Execution Environments (TEEs) to guarantee authenticity and integrity properties of applications, and to secure control of input and output devices. More specifically, we guarantee that if an output is produced by the application, it was allowed to be produced by the application's source code based on an authentic trace of inputs. We present an integrated open-source framework to develop, deploy, and use such applications across heterogeneous TEEs. Beyond authenticity and integrity, our framework optionally provides confidentiality and a notion of availability, and facilitates software development at a high level of abstraction over the platform-specific TEE layer. We support event-driven programming to develop distributed enclave applications in Rust and C for heterogeneous TEE, including Intel SGX, ARM TrustZone and Sancus. In this article we discuss the workings of our approach, the extensions we made to the Sancus processor, and the integration of our development model with commercial TEEs. Our evaluation of security and performance aspects show that TEEs, together with our programming model, form a basis for powerful security architectures for dependable systems in domains such as Industrial Control Systems and the Internet of Things, illustrating our framework's unique suitability for a broad range of use cases which combine cloud processing, mobile and edge devices, and lightweight sensing and actuation.

description: Carbon burning is a crucial process for a number of important astrophysical scenarios. The lowest measured energy is around E$_{\rm c.m.}$=2.1 MeV, only partially overlapping with the energy range of astrophysical interest. The currently adopted reaction rates are based on an extrapolation which is highly uncertain because of potential resonances existing in the unmeasured energy range and the complication of the effective nuclear potential. By comparing the cross sections of the three carbon isotope fusion reactions, ${}^{12}$C+${}^{12}$C, ${}^{12}$C+${}^{13}$C and ${}^{13}$C+${}^{13}$C, we have established an upper limit on the molecular resonance strengths in ${}^{12}$C+${}^{12}$C fusion reaction. The preliminary results are presented and the impact on nuclear astrophysics is discussed.

description: We provide a solution to the problem of determining whether a target pure state can be asymptotically prepared using dissipative Markovian dynamics under fixed locality constraints. Beside recovering existing results for a large class of physically relevant entangled states, our approach has the advantage of providing an explicit stabilization test solely based on the input state and constraints of the problem. Connections with the formalism of frustration-free parent Hamiltonians are discussed, as well as control implementations in terms of a switching output-feedback law.

description: Many research questions in public health and medicine concern sustained interventions in populations defined by substantive priorities. Existing methods to answer such questions typically require a measured covariate set sufficient to control confounding, which can be questionable in observational studies. Differences-in-differences relies instead on the parallel trends assumption, allowing for some types of time-invariant unmeasured confounding. However, most existing difference-in-differences implementations are limited to point treatments in restricted subpopulations. We derive identification results for population effects of sustained treatments under parallel trends assumptions. In particular, in settings where all individuals begin follow-up with exposure status consistent with the treatment plan of interest but may deviate at later times, a version of Robins' g-formula identifies the intervention-specific mean under SUTVA, positivity, and parallel trends. We develop consistent asymptotically normal estimators based on inverse-probability weighting, outcome regression, and a double robust estimator based on targeted maximum likelihood. Simulation studies confirm theoretical results and support the use of the proposed estimators at realistic sample sizes. As an example, the methods are used to estimate the effect of a hypothetical federal stay-at-home order on all-cause mortality during the COVID-19 pandemic in spring 2020 in the United States.

Product design for sustainability: integrated scales of design and production
Creators: name: Dogan, Cagla
Publisher: name: Environmental Design
Year: 2007

description: Bibliography: p. 229-239
description: Some pages are in colour.
description: This thesis presented here introduces outcomes of a design research project and provides new insights into an integrated concept for sustainable product design. This project focuses on re-integrating 'localization' in product design, production, use and post-use in order to better address sustainable principles (i.e. environmental, sociocultural and economic). The original concept developed in this research has been termed 'Integrated Scales of Design and Production for Sustainability' (ISDPS). The approach reappraises current norms of product production and disposal by offering new 'integrated thinking' across the lifespan of contemporary products. This concept proposes integrating mass-production of certain product components with local parts production, locally appropriate design and research, and local services for product repair, reuse and recovery to better address a variety of sustainable criteria. An overview of the concept is given, together with primary research findings from product examples in the furniture and lighting sectors (at the mass-, batch and craft production scales). The research includes interviews with designers, manufacturers and environmental specialists, and key aspects of the design and production processes are highlighted, such as material selection, production processes, and connectivity with end users, local suppliers and/or manufacturers. Several 'product case pairs ' are examined that include: Furniture: mass-produced panel design for a modular office system and craft produced entrance table; Furniture and Lighting: batch produced industrial design ceramic lamp and chair, and locally produced craft lamp and chair; Furniture: further examination of design and production of four small-scale furniture design companies. The study has a design-based research component and so it includes design explorations and propositions in furniture and lighting that enable local producers at the batch-production scale to create products, to contribute to material culture, and to express local tastes and cultural preferences (i.e. ephemeral, adaptable, integrated design). These exploratory designs lead to further conclusions, and provide design insights into new product categories that are currently predominantly designed, produced and distributed at the mass-production scale (e.g. small household appliances, electronics, etc.). The conclusions from this research provide a substantial basis to better understand and define the feasibility and potential of 'design for sustainability' and the potential contribution of the "ISDPS" concept.

description: In this article, we continue our mathematical study of organic solar cells (OSCs) and propose a two-scale (micro- and macro-scale) model of heterojunction OSCs with interface geometries characterized by an arbitrarily complex morphology. The microscale model consists of a system of partial and ordinary differential equations in an heterogeneous domain, that provides a full description of excitation/transport phenomena occurring in the bulk regions and dissociation/recombination processes occurring in a thin material slab across the interface. The macroscale model is obtained by a micro-to-macro scale transition that consists of averaging the mass balance equations in the normal direction across the interface thickness, giving rise to nonlinear transmission conditions that are parametrized by the interfacial width. These conditions account in a lumped manner for the volumetric dissociation/recombination phenomena occurring in the thin slab and depend locally on the electric field magnitude and orientation. Using the macroscale model in two spatial dimensions, device structures with complex interface morphologies, for which existing data are available, are numerically investigated showing that, if the electric field orientation relative to the interface is taken into due account, the device performance is determined not only by the total interface length but also by its shape.
Electronic viscosity and energy relaxation in neutral graphene

description: We explore hydrodynamics of Dirac fermions in neutral graphene in the Corbino geometry. In the absence of magnetic field, the bulk Ohmic charge flow and the hydrodynamic energy flow are decoupled. However, the energy flow does affect the overall resistance of the system through viscous dissipation and energy relaxation that has to be compensated by the work done by the current source. Solving the hydrodynamic equations, we find that local temperature and electric potential are discontinuous at the interfaces with the leads as well as the device resistance and argue that this makes Corbino geometry a feasible choice for an experimental observation of the Dirac fluid.

description: We have developed a spherically symmetric dynamical model of a dwarf spheroidal galaxy using the Schwarzschild method. This type of modelling yields constraints both on the total mass distribution (e.g. enclosed mass and scale radius) as well as on the orbital structure of the system modelled (e.g. velocity anisotropy). Therefore not only can we derive the dark matter content of these systems, but also explore possible formation scenarios. Here we present preliminary results for the Sculptor dSph. We find that the mass of Sculptor within 1kpc is 8.5\times10^(7\pm0.05) M\odot, its anisotropy profile is tangentially biased and slightly more isotropic near the center. For an NFW profile, the preferred concentration (~15) is compatible with cosmological models. Very cuspy density profiles (steeper than NFW) are strongly disfavoured for Sculptor.

Development of strategies to enhance the contribution of hematopoietic cells to skeletal muscle repair
Creators: name: Long, Michael Anthony
Publisher: name: University of British Columbia
Year: 2011

description: The ability of bone marrow derived cells to contribute to skeletal muscle repair may represent a novel means of cell therapy for myopathies. However, this phenomenon takes place at exceedingly low frequencies and has failed to yield any measurable functional improvement in disease models. In an effort to increase the efficiency of this process, we designed Cre/loxP-based tracing strategies to identify the lineages and mechanisms involved. However, these experiments were complicated by a previously unknown limitation of common Cre-reporter strains. We have studied the Z/AP, Z/EG and R26R-EYFP reporter strains and have demonstrated that although each reporter can be reliably activated by Cre during early development, exposure to Cre in adult hematopoietic cells results in a much lower frequency of reporter-positive cells in the Z/AP or Z/EG strains than in the R26R-EYFP strain. In reporter-negative cells derived from the Z/AP and Z/EG strains, the transgenic promoter is methylated and Cre-mediated recombination of the locus is inhibited. These findings suggest that the Z/AP and Z/EG strains may not be suitable for the investigation of developmental plasticity in adult models. As bone marrow derived cells are now believed to contribute to skeletal muscle repair primarily via fusion, we also constructed a chimeric measles hemagglutinin, Hα7, which efficiently mediates the fusion of diverse cell types with skeletal muscle. When compared directly to polyethylene glycol in vitro, Hα7 consistently generated a ten to fifteen fold increase in heterokaryon yield and induced insignificant levels of toxicity. More importantly, Hα7 was also capable of increasing the contribution of mouse and human bone marrow derived cells to skeletal muscle repair in vivo.

Multiculturalism is Dead, Long Live Nationalism: The Identitarian Projects of the Centre Right and the Far Right in Great Britain, France and Germany

description: Inspired by the coherent anti-multiculturalist rhetoric of the centre right and far right political parties in Great Britain, France and Germany in 2011 and guided by the critical theory, constructionism and critical discourse analysis, the thesis compares and contrasts centre right and far right political discourses to reveal convergences and divergences in their identitarian projects. The thesis suggests that the theoretical distinction between the legitimate centre right and the dangerous far right is not fully empirically justified in the area of identitarian politics as the centre right vying with the far right for electoral success and the far right eager to break the cordon sanitaire share many commonalities in their topic problematization and discursive strategies of legitimation as well as in the potential effects of their respective discourses. The thesis argues that both the centre right and the far right resort to the risk framework to legitimate their interest in and exploitation of identity, which results in stigmatisation, securitisation and criminalisation of the threatening Other. It demonstrates that the far right seeking mainstreaming resorts to the discourse of rights and the problematization of seemingly legitimate political issues, such as the affirmative action, multiculturalism, supra-nationalism and globalisation, which leads to the convergence of the two political camps in their covert reification of the mythical majority’s privilege and pre-emption of minorities’ claims-making. It also demonstrates that the centre right seeking political relevance exploits the topics and discursive moves traditionally associated with the far right, such as the risks of ‘uncontrolled’ immigration, ‘failed’ integration and ‘growing’ insecurity. Examining the two camp’s civic and nationalist national identity markers, the thesis demonstrates that, despite the alleged acceptability of the civic markers associated with the centre right, both camps and types of markers normalise the concepts of intrinsic national homogeneity and inter-national incompatibility, legitimate the surveillance and stigmatisation of difference and reify the moral and cultural superiority of the mythical majority defined by Christian European ancestry.

description: Bei der Anwendung des europäischen Beihilfenrechts als einer der Grundpfeiler der unionalen Wirtschaftsordnung auf nationale Steuersysteme und -maßnahmen kommt es immer wieder zu Reibungen. Der folgende Beitrag untersucht – unter der Annahme der Erfüllung des Selektivitätskriteriums – zum einem die Anwendbarkeit des Art. 107 Abs. 1 AEUV auf Steuervergünstigungen im Allgemeinen und im Speziellen die Anwendung des „Market Economy Operator Tests“ auf die selbigen. Dabei werden anhand der unterschiedlichen erdenklichen Konstellationen Fallgruppen entwickelt und die bisherige Rechtsprechung in diesem Bereich den verschieden Fallgruppen zugeordnet. Insbesondere wird dabei auf das Urteil des EuGH in der Rs. EdF eingegangen. When applying the European state aid regime as one of the fundamentals of the economic order of the Union to national tax systems and measures, frictions frequently occur. The following article scrutinizes – under the assumption that the criterion of selectivity is fulfilled – the applicability of Art. 107 para. 1 TFEU to tax advantages in general and specifically focuses on the applicability of the “market economy operator test” to those benefits. On the basis of the different imaginable constellations, a categorization is developed and the current jurisprudence in this area is matched to those categories. In particular the judgment of the ECJ in the case EdF is examined.

Fantastical disruptions: representation and ideology in historical fiction for children
Creators: name: Grattan, Tricia Charlotte
Publisher: name: University of Calgary
Year: 2007

description: Bibliography: p. 139-148
description: This thesis examines how the insertion of fantasy into historical fiction for children offers a subversive challenge to monologism. As Rosemary Jackson explains, "the fantastic traces the unsaid and the unseen of culture: that which has been silenced" (4). I draw on the work of Linda Hutcheon and Mikhail Bakhtin to argue that the fantastical can efface straightforward equations of history with "truth," permitting alternate perspectives. I first examine Julius Lester's use of magical realism and tall tales to question conceptions of slavery. Next, I turn to the historical narratives of Paul Yee, and demonstrate how effectively the ghost story can create a multifaceted history that links past to present. I also investigate three times lip novels that demonstrate the genre's strengths and limitations. As long as historical fiction influences how children conceive of their pasts, presents and futures, fantasy's capacity to inte1ject dialogism into these understandings will remain important.

description: Recently, integrated photonic circuits have brought new capabilities to electron microscopy and been used to demonstrate efficient electron phase modulation and electron-photon correlations. Here, we quantitatively analyze the feasibility of high fidelity and high purity quantum state heralding using a free electron and a photonic integrated circuit with parametric coupling, and propose schemes to shape useful electron and photonic states in different application scenarios. Adopting a dissipative quantum electrodynamics treatment, we formulate a framework for the coupling of free electrons to waveguide spatial-temporal modes. To avoid multimode-coupling induced state decoherence, we show that with proper waveguide design, the interaction can be reduced to a single-mode coupling to a quasi-TM00 mode. In the single-mode coupling limit, we go beyond the conventional state ladder treatment, and show that the electron-photon energy correlations within the ladder subspace can still lead to a fundamental purity and fidelity limit on complex optical and electron state preparations through heralding schemes. We propose applications that use this underlying correlation to their advantage, but also show that the imposed limitations for general applications can be overcome by using photonic integrated circuits with an experimentally feasible interaction length, showing its promise as a platform for free-electron quantum optics.

description: Am 9.4.2014 hat die Kommission einen Richtlinienvorschlag für eine Societas Unius Personae (SUP) veröffentlicht. Leitgedanke des Vorhabens ist es, insbesondere kleinen und mittleren Unternehmen die Etablierung und Leitung einer grenzüberschreitenden Konzernstruktur zu ermöglichen. Zentrale Aspekte wie die Organpflichten der Tochtergeschäftsführer wurden jedoch bislang keiner Regelung zugeführt. Der folgende Beitrag setzt sich mit der Frage auseinander, inwiefern die SUP den Anforderungen an einen europaweit einheitlich einsetzbaren Konzernbaustein gerecht wird. Zudem werden einzelne Gestaltungsmöglichkeiten für eine Normierung der Organpflichten der Tochtergeschäftsführer diskutiert, insbesondere die Pflicht zur Befolgung von Weisungen der Konzernleitung. On 4 September 2014, the Commission published a proposal for a Directive on a Societas Unius Personae (SUP). The guiding principle of the draft is to enable small and mid-sized companies to establish and manage transborder group structures. However, fundamental aspects such as the duties of subsidiaries’ directors have not been subject to regulation yet. This paper examines whether the SUP meets the requirements of a corporate group building block that is applicable Europe-wide. Moreover, various possibilities of regulating subsidiaries’ directors’ duties are discussed, especially the duty to comply with instructions of the parent company.

description: The fundamental action of the bubble-driven inertial micropump is investigated. The pump has no moving parts and consists of a thermal resistor placed asymmetrically within a straight channel connecting two reservoirs. Using numerical simulations, the net flow is studied as a function of channel geometry, resistor location, vapor bubble strength, fluid viscosity, and surface tension. Two major regimes of behavior are identified: axial and non-axial. In the axial regime, the drive bubble either remains inside the channel or continues to grow axially when it reaches the reservoir. In the non-axial regime the bubble grows out of the channel and in all three dimensions while inside the reservoir. The net flow in the axial regime is parabolic with respect to the hydraulic diameter of the channel cross-section but in the non-axial regime it is not. From numerical modeling, it is determined that the net flow is maximal when the axial regime crosses over to the non-axial regime. To elucidate the basic physical principles of the pump, a phenomenological one-dimensional model is developed and solved. A linear array of micropumps has been built using silicon-SU8 fabrication technology, and semi-continuous pumping across a 2 mm-wide channel has been demonstrated experimentally. Measured variation of the net flow with fluid viscosity is in excellent agreement with simulation results.

description: Objective. This study examined the relationship of multiple mild traumatic brain injuries (mTBIs) and psychological resilience to persistent post-concussion symptoms (PCS). Methods. Participants (N = 65), ages 8-18 years, who sustained multiple mTBIs (n = 24), a single mTBI (n = 22), or an orthopaedic injury (OI; n = 19) were recruited from a children’s hospital in Calgary, Alberta. Resilience was measured using the Connor-Davidson Resilience Scale (CD-RISC) and PCS were measured using the Post-Concussion Symptom Inventory (PCSI). Results. The multiple mTBI group and low psychological resilience were significant predictors of PCS. Conclusions. Sustaining multiple mTBIs may increase a child’s risk of persistent PCS; however, high psychological resilience may serve as a protective factor, regardless of the number of injuries a child sustains. Results of this study provide support for interventions aimed at increasing psychological resilience in order to improve outcomes for children suffering from persistent PCS after mTBI.

description: Background: Early mortality after dialysis initiation is common among older adults. Information on an individual’s risk of death may influence the decision to initiate dialysis. Objective: To develop a clinical risk prediction tool for mortality within six and twelve months of dialysis initiation, for older adults. Methods: Eligible individuals were adults age ≥65 who initiated chronic dialysis between May 1, 2003 and March 31, 2012. Measures of demographics, laboratory values, health-usage and comorbidity were potential predictors of early mortality. We used logistic regression to predict mortality, and created a point score system. Results: The six- and twelve-month tools included age, glomerular filtration rate, atrial fibrillation, lymphoma, chronic heart failure, prior hospitalization and metastatic cancer. Cirrhosis and late referral to nephrologist were also in the twelve-month score. Model discrimination was 0.72 for each outcome. Conclusion: These tools may aide decision making for older adults considering dialysis.

description: Die folgende Arbeit setzt sich mit dem wenig bekannten § 357 StGB auseinander. Aufgrund dieser Norm wird ein (Amts-)Vorgesetzter oder ein Aufsichtsbeamter (Abs. 2), der einen Untergebenen zu einer rechtswidrigen Tat im Amt verleitet oder zu verleiten unternimmt oder eine solche Tat geschehen lässt, immer als Täter dieser Tat bestraft. Die Vorschrift soll dabei der besonderen Verantwortlichkeit des Vorgesetzten Rechnung tragen. Zunächst wird auf den Tatbestand sowie auf Schwierigkeiten bei der Auslegung seines Wortlauts eingegangen. Es folgt eine kriminalpolitische Begutachtung, bei der insbesondere versucht wird, die niedrigen Fallzahlen zu erklären. Zudem wird die Frage erörtert, ob der Tatbestand überhaupt noch aktuell und notwendig ist. Dies wird nach einer ausführlichen Diskussion schließlich bejaht. Abschließend werden mögliche Gesetzesänderungen diskutiert.

description: In the presence of time-reversal symmetry, quantum interference gives strong corrections to the electric conductivity of disordered systems. The self-interference of an electron wavefunction traveling time-reversed paths leads to effects such as weak localization and universal conductance fluctuations. Here, we investigate the effects of broken time-reversal symmetry in a driven artificial two-level system. Using a superconducting flux qubit, we implement scattering events as multiple Landau-Zener transitions by driving the qubit periodically back and forth through an avoided crossing. Interference between different qubit trajectories give rise to a speckle pattern in the qubit transition rate, similar to the interference patterns created when coherent light is scattered off a disordered potential. Since the scattering events are imposed by the driving protocol, we can control the time-reversal symmetry of the system by making the drive waveform symmetric or asymmetric in time. We find that the fluctuations of the transition rate exhibit a sharp peak when the drive is time-symmetric, similar to universal conductance fluctuations in electronic transport through mesoscopic systems.
The Haiti Cholera case – Limits to the Immunity of the United Nations from Domestic Jurisdiction?

description: Die zunehmenden Aktivitäten der Vereinten Nationen (VN), insbesondere im Bereich der Friedenssicherung, sind eine Herausforderung für die Balance zwischen individuellem Rechtsschutz und funktioneller Immunität der VN wie sie im Übereinkommen über die Vorrechte und Immunitäten der VN von 1946 und im Völkergewohnheitsrecht niedergelegt sind. Am Beispiel der Cholera-Krise in Haiti wird das Für und Wider einer Aufhebung der Immunität der VN abgewogen. Hierbei werden Entwicklungen in der Rechtsprechung nationaler und internationaler Gerichte sowie Argumentationslinien aus dem Recht der Staatenimmunität einbezogen. Der folgende Beitrag kommt zu dem Schluss, dass eine Aufhebung der Immunität der VN durch staatliche Gerichte in der Abwesenheit eines alternativen Streitbelegungsmechanismus gerechtfertigt ist. The every expanding activities of the United Nations (UN), especially its peacekeeping missions, challenge the equilibrium of access to justice and the UN’s functional immunity as recognized under the Convention on the Privileges and Immunities of the United Nations and customary international law. Using the Haiti Cholera case as a case study, this article discusses why the UN’s immunity may or may not prevail. Taking into account the case-law of national and international courts and analogous developments in the law of State immunity, this article concludes that national courts may lift the UN’s immunity if the the UN fails to provide for an alternative dispute settlement mechanism.

description: An ongoing shortage of suitable woody waste materials due to the many recent saw-mill closures in Canada has been a major concern for particleboard manufacturers. The existing particleboard plants are currently competing with other industries for the scarce fiber resources available and facing significant competition from the cheap lower grade substitutes being imported from China. This thesis presents a solution through the development of hollow core sandwich panels for modular furniture components that serve the same function as solid slabs of particleboard but with reduced amounts of raw material inputs (wood and resin). Through a series of preliminary experiments, prototype honeycomb sandwich panels were fabricated with a variety of face and core materials. The characteristic effects of different types of Kraft paper honeycomb materials, its cell size, orientation and cell wall height as well as the influence of different wood-based face materials on the sandwich strength and stiffness properties were established. The results indicate that by combining thicker (6 mm) face sheet materials with Kraft paper honeycomb with cell size less than 16 mm, cell wall height 38 mm and oriented with the core ribbon direction perpendicular to the long axis of the panel, a sandwich panel with significant strength properties can be produced. The findings also imply that the performance of the honeycomb sandwich panels can further be improved through the application of edge rail enforcements and edge band application. The outcome of this study has the potential of reducing the total weight of finished products for the furniture manufacturers and provides avenues for product differentiation.
N$^2$M$^2$: Learning Navigation for Arbitrary Mobile Manipulation Motions in Unseen and Dynamic Environments

description: Despite its importance in both industrial and service robotics, mobile manipulation remains a significant challenge as it requires a seamless integration of end-effector trajectory generation with navigation skills as well as reasoning over long-horizons. Existing methods struggle to control the large configuration space, and to navigate dynamic and unknown environments. In previous work, we proposed to decompose mobile manipulation tasks into a simplified motion generator for the end-effector in task space and a trained reinforcement learning agent for the mobile base to account for kinematic feasibility of the motion. In this work, we introduce Neural Navigation for Mobile Manipulation (N$^2$M$^2$) which extends this decomposition to complex obstacle environments and enables it to tackle a broad range of tasks in real world settings. The resulting approach can perform unseen, long-horizon tasks in unexplored environments while instantly reacting to dynamic obstacles and environmental changes. At the same time, it provides a simple way to define new mobile manipulation tasks. We demonstrate the capabilities of our proposed approach in extensive simulation and real-world experiments on multiple kinematically diverse mobile manipulators.
