description: The task of integrating a large number of independent ODE systems arises in various scientific and engineering areas. For nonstiff systems, common explicit integration algorithms can be used on GPUs, where individual GPU threads concurrently integrate independent ODEs with different initial conditions or parameters. One example is the fifth-order adaptive Runge-Kutta-Cash-Karp (RKCK) algorithm. In the case of stiff ODEs, standard explicit algorithms require impractically small time-step sizes for stability reasons, and implicit algorithms are therefore commonly used instead to allow larger time steps and reduce the computational expense. However, typical high-order implicit algorithms based on backwards differentiation formulae (e.g., VODE, LSODE) involve complex logical flow that causes severe thread divergence when implemented on GPUs, limiting the performance. Therefore, alternate algorithms are needed. A GPU-based Runge-Kutta-Chebyshev (RKC) algorithm can handle moderate levels of stiffness and performs significantly faster than not only an equivalent CPU version but also a CPU-based implicit algorithm (VODE) based on results shown in the literature. In this chapter, we present the mathematical background, implementation details, and source code for the RKCK and RKC algorithms for use integrating large numbers of independent systems of ODEs on GPUs. In addition, brief performance comparisons are shown for each algorithm, demonstrating the potential benefit of moving to GPU-based ODE integrators.

description: In this data report we discuss reprocessing of the Space Technology 5 (ST5) magnetometer database for inclusion in NASA's Coordinated Data Analysis Web (CDAWeb) virtual observatory. The mission consisted of three spacecraft flying in elliptical orbits, from 27 March to 27 June 2006. Reprocessing includes (1) transforming the data into the Modified Apex Coordinate System for projection to a common reference altitude of 110km, (2) correcting gain jumps, and (3) validating the results. We display the averaged magnetic perturbations as a keogram, which allows direct comparison of the full-mission data with the solar wind values and geomagnetic indices.With the data referenced to a common altitude, we find the following: (1) Magnetic perturbations that track the passage of corotating interaction regions and high-speed solar wind; (2) unexpectedly strong dayside perturbations during a solstice magnetospheric sawtooth oscillation interval characterized by a radial interplanetary magnetic field (IMF) component that may have enhanced the accompanying modest southward IMF; and (3) intervals of reduced magnetic perturbations or "calms," associated with periods of slow solar wind, interspersed among variable-length episodic enhancements. These calms aremost evidentwhen the IMF is northward or projectswith a northward component onto the geomagnetic dipole. The reprocessed ST5 data are in very good agreement with magnetic perturbations from the Defense Meteorological Satellite Program (DMSP) spacecraft, which we also map to 110km. We briefly discuss the methods used to remap the ST5 data and the means of validating the results against DMSP. Our methods form the basis for future intermission comparisons of space-based magnetometer data.

Subjects: Other education not elsewhere classified

description: Clinicians and researchers agree that, in addition to acutely painful episodes such as heel lancing, infants in the neonatal intensive care unit (NICU) and high dependency unit (HDU) may also experience other types of pain such as chronic pain. Although chronic pain is defined as pain lasting three months or more, such a definition is not appropriate for infants in the NICU or HDU due to their younger age. The aim of this thesis was to develop a clear and clinically valid definition of chronic pain in infants admitted to the NICU and HDU using multiple methodologies. The thesis begins with an exploration of the ethical implications of neonatal and infant pain in the context of clinical pain management. Following this exploration, the thesis begins to develop a definition of chronic pain. First, a systematic review demonstrates that many studies refer to various types of non-acute pain such as chronic pain, however a consistent definition was lacking. Second, analysis of real-world clinical data demonstrates that chronic pain, according to current descriptions, is statistically evident in neonates and infants who underwent major surgery. Third, an expert panel is detailed which leads to a consensus definition of chronic pain in infants in the NICU and HDU, and which is then validated using a global survey of neonatal clinicians. Fourth, exploratory and confirmatory factor analyses of a non-acute pain assessment tool reveal the constructs underlying this instrument commonly used in the NICU and HDU. Fifth, a prognostic and clinical definition of chronic pain in neonates is currently underway in a prospective cohort study to determine whether longer periods of treated pain result in adverse effects on neurodevelopment, psychosocial wellbeing, and growth outcomes. Therefore, this thesis provides 1) an ethical analysis of neonatal pain management, 2) a systematic review of non-acute pain in critically ill neonates and infants, 3) a statistical definition of chronic pain in critically ill neonates and infants, 3) a consensus definition of chronic pain, 4) an analysis of non-acute pain and assessment, and 6) a protocol for a prospective cohort study to develop a prognostic and clinical definition of chronic pain. The thesis takes an important step towards guiding the assessment, prevention, and treatment of chronic pain in neonates and infants in the NICU.

description: Despite initial responses to hormone treatment, metastatic prostate cancer invariably evolves to a lethal state. To characterize the intra-patient evolutionary relationships of metastases that evade treatment, we perform genome-wide copy number profiling and bespoke approaches targeting the androgen receptor (AR) on 167 metastatic regions from 11 organs harvested post-mortem from 10 men who died from prostate cancer. We identify diverse and patient-unique alterations clustering around the AR in metastases from every patient with evidence of independent acquisition of related genomic changes within an individual and, in some patients, the co-existence of AR-neutral clones. Using the genomic boundaries of pan-autosome copy number changes, we confirm a common clone of origin across metastases and diagnostic biopsies, and identified in individual patients, clusters of metastases occupied by dominant clones with diverged autosomal copy number alterations. These autosome-defined clusters are characterized by cluster-specific AR gene architectures, and in two index cases are topologically more congruent than by chance (p-values 3.07 × 10-8 and 6.4 × 10-4). Integration with anatomical sites suggests patterns of spread and points of genomic divergence. Here, we show that copy number boundaries identify treatment-selected clones with putatively distinct lethal trajectories.

description: Introduction: Due to the increasing complexity and diversity of work tasks in teams, teams need team members who are dedicated and energetic, both characteristics attributed to team members’ work engagement. Especially in the domain of health care, high demands at work impact professionals’ work engagement. Despite teams being the main work unit in this domain, team research on antecedents of work engagement has been neglected. The present study examines the role of team behaviors such as reflection activities in the relationships between demands at work and team members’ work engagement. In doing so, the study aims to extend findings on team behaviors by considering cognitive and work-task related team behaviors as well as team behaviors that focus on emotional aspects. Methods: Data of 298 team members of 52 interdisciplinary teams of health and social care organizations which provide care and assistance were collected in this cross-sectional survey study. Relationships between team demands at work, team learning behaviors, dealing with emotions in the team and team members’ work engagement were estimated in a mediation model using structural equation modeling (SEM). Results: The results indicate that team members’ work engagement is positively related to team learning behaviors and dealing with emotions in the team. Cognitive team demands at work such as the complexity of work tasks, were found to relate positively to team members’ work engagement, while emotional team demands such as the amount of emotional labor at work had a negative relationship. Team learning behaviors and dealing with emotions in the team were found to mediate the relationship between team demands at work and team members’ work engagement. Discussion: Our results provide insights into the actual behavior of teams in the domain of health care, both on cognitive and emotional aspects, and the capability of team learning behaviors and dealing with emotions in the team to mediate the relationship between team demands at work and team members’ work engagement. The findings encourage future researchers and practitioners to address cognitive, emotional and motivational components in team research to provide a better understanding of team conditions, team behavior and team outcomes.

description: A graph $G$ is \textit{$k$-critical} if $χ(G) = k$ and every proper subgraph of $G$ is $(k - 1)$-colorable, and if $L$ is a list-assignment for $G$, then $G$ is \textit{$L$-critical} if $G$ is not $L$-colorable but every proper induced subgraph of $G$ is. In 2014, Kostochka and Yancey proved a lower bound on the average degree of an $n$-vertex $k$-critical graph tending to $k - \frac{2}{k - 1}$ for large $n$ that is tight for infinitely many values of $n$, and they asked how their bound may be improved for graphs not containing a large clique. Answering this question, we prove that for $\varepsilon \leq 2.6\cdot10^{-10}$, if $k$ is sufficiently large and $G$ is a $K_{ω+ 1}$-free $L$-critical graph where $ω\leq k - \log^{10}k$ and $L$ is a list-assignment for $G$ such that $|L(v)| = k - 1$ for all $v\in V(G)$, then the average degree of $G$ is at least $(1 + \varepsilon)(k - 1) - \varepsilon ω- 1$. This result implies that for some $\varepsilon > 0$, for every graph $G$ satisfying $ω(G) \leq \mathrm{mad}(G) - \log^{10}\mathrm{mad}(G)$ where $ω(G)$ is the size of the largest clique in $G$ and $\mathrm{mad}(G)$ is the maximum average degree of $G$, the list-chromatic number of $G$ is at most $\left\lceil (1 - \varepsilon)(\mathrm{mad}(G) + 1) + \varepsilonω(G)\right\rceil$.

description: Motivated by the significant interaction of convection, rotation and magnetic field in many astrophysical objects, we investigate the interplay between large-scale flows driven by rotating convection and an imposed magnetic field. We utilise a simple model in two dimensions comprised of a plane layer that is rotating about an axis inclined to gravity. It is known that this setup can result in strong mean flows; we numerically examine the effect of an imposed horizontal magnetic field on such flows. We show that increasing the field strength in general suppresses the time-dependent mean flows, but in some cases it organises them leading to stronger time-averaged flows. Further, we discuss the effect of the field on the correlations responsible for driving the flows and the competition between Reynolds and Maxwell stresses. A change in behaviour is observed when the (fluid and magnetic) Prandtl numbers are decreased. In the smaller Prandtl number regime, it is shown that significant mean flows can persist even when the quenching of the overall flow velocity by the field is relatively strong.

description: High-resolution in situ measurements from the three Swarm spacecraft, in a string-of-pearls configuration, provide new insights about the combined role of flow channel events and particle impact ionization in creating $\textit{F}$ region electron density structures in the northern Scandinavian dayside cusp. We present a case of polar cap patch formation where a reconnection-driven low-density relative westward flow channel is eroding the dayside solar-ionized plasma but where particle impact ionization in the cusp dominates the initial plasma structuring. In the cusp, density features are observed which are twice as dense as the solar-ionized background. These features then follow the polar cap convection and become less structured and lower in amplitude. These are the first in situ observations tracking polar cap patch evolution from creation by plasma transport and enhancement by cusp precipitation, through entrainment in the polar cap flow and relaxation into smooth patches as they approach the nightside auroral oval.

description: The formation of two sperm cells by the angiosperm male gametophyte is essential for seed production and ultimately for plant productivity. The MYB transcription factor DUO1 POLLEN 1 (DUO1) is a key regulator of male gametogenesis in Arabidopsis thaliana and forms a germline-specific regulatory module with the functionally redundant genes DUO1-ACTIVATED ZINC FINGER1 (DAZ1) and DAZ2. This regulatory module is conserved in some bryophytes, but its wider role among angiosperms remains unexplored. Here the DUO1-DAZ1 regulatory module is investigated in tomato (Solanum lycopersicum L.), wheat (Triticum aestivum L.) and barley (Hordeum vulgare L.). Two DUO1 orthologues and a single DAZ1 orthologue were identified in the genomes of tomato and barley, while three DUO1 and three DAZ1 homoeologues are present in the bread wheat genome. Analysis of RNA-seq data revealed that transcripts for DUO1 and DAZ1 are expressed in male reproductive tissues in each of these crops. Plants carrying knockout alleles disrupting SlDUO1 or SlDAZ1 function in tomato were shown to block generative cell division and the transmission of SlDUO1 or SlDAZ1 mutant alleles through pollen. Further, the generative cell was round in mutant alleles compared to elongated generative cell in wild type. Quantitative analysis of RNA expression in loss of function mutants also indicated that regulatory interactions of the DUO1-DAZ1 module are conserved in tomato. Preliminary analysis of knockout alleles disrupting TaDUO1 function in wheat indicate that generative cell division and sperm cell formation are affected. Plants homozygous for knock out alleles in one of two barley DUO1 orthologues were fertile and showed no generative cell defects. In summary, the data presented demonstrate an essential role for the DUO1-DAZ1 module in tomato and support the hypothesis that this regulatory module is more widely conserved in some key crop plants.

description: -The explosive trend of smartphone usage as the most effective and convenient communication tools of human life in recent years make developers build ever more complex smartphone applications. Gaming, navigation, video editing, augmented reality, and speech recognition applications require considerable computational power and energy. Although smart- phones have a wide range of capabilities - GPS, WiFi, cameras - their inherent limitations - frequent disconnections, mobility - and significant constraints - size, lower weights, longer battery life - make difficult to exploiting their full potential to run complex applications. Several research works have proposed solutions in application offloading domain, but few ones concerning the highly changing properties of the environment. To address these issues, we realize an automated application offloading middleware, ACOMMA, with dynamic and re-adaptable decision-making engine. The decision engine of ACOMMA is based on an ant- inspired algorithm.

It is found that the widths of the mass distribution increases monotonically with excitation energy, indicating the absence of quasi-fission for both reactions. This is contrary to two recent claims of the presence of quasi-fission in the above mentioned reactions.

description: We consider the spectral gap of a uniformly chosen random $(d_1,d_2)$-biregular bipartite graph $G$ with $|V_1|=n, |V_2|=m$, where $d_1,d_2$ could possibly grow with $n$ and $m$. Let $A$ be the adjacency matrix of $G$. Under the assumption that $d_1\geq d_2$ and $d_2=O(n^{2/3}),$ we show that $λ_2(A)=O(\sqrt{d_1})$ with high probability. As a corollary, combining the results from Tikhomirov and Youssef (2019), we showed that the second singular value of a uniform random $d$-regular digraph is $O(\sqrt{d})$ for $1\leq d\leq n/2$ with high probability. Assuming $d_2$ is fixed and $d_1=O(n^2)$, we further prove that for a random $(d_1,d_2)$-biregular bipartite graph, $|λ_i^2(A)-d_1|=O(\sqrt{d_1})$ for all $2\leq i\leq n+m-1$ with high probability. The proofs of the two results are based on the size biased coupling method introduced in Cook, Goldstein, and Johnson (2018) for random $d$-regular graphs and several new switching operations we defined for random bipartite biregular graphs.

description: One can obtain exact information about Virasoro conformal blocks by analytically continuing the correlators of degenerate operators. We argued in recent work that this technique can be used to explicitly resolve information loss problems in AdS$_3$/CFT$_2$. In this paper we use the technique to perform calculations in the small $1/c \propto G_N$ expansion: (1) we prove the all-orders resummation of logarithmic factors $\propto \frac{1}{c} \log z$ in the Lorentzian regime, demonstrating that $1/c$ corrections directly shift Lyapunov exponents associated with chaos, as claimed in prior work, (2) we perform another all-orders resummation in the limit of large $c$ with fixed $cz$, interpolating between the early onset of chaos and late time behavior, (3) we explicitly compute the Virasoro vacuum block to order $1/c^2$ and $1/c^3$, corresponding to $2$ and $3$ loop calculations in AdS$_3$, and (4) we derive the heavy-light vacuum blocks in theories with $\mathcal{N}=1,2$ superconformal symmetry.

description: Early-life sleep disruption (ELSD) has been shown to have long-lasting effects on social behaviour in adult prairie voles (Microtus ochrogaster), including impaired expression of pair bonding during partner preference testing. However, due to the limitations of manual behaviour tracking, the effects of ELSD across the time course of pair bonding have not yet been described, hindering our ability to trace mechanisms. Here, we used pose estimation to track prairie voles during opposite-sex cohabitation, the process leading to pair bonding. Male–female pairs were allowed to interact through a mesh divider in the home cage for 72 h, providing variables of body direction, distance-to-divider and locomotion speed. We found that control males displayed periodic patterns of body orientation towards females during cohabitation. In contrast, ELSD males showed reduced duration and ultradian periodicity of these body orientation behaviours towards females. Furthermore, in both sexes, ELSD altered spatial and temporal patterns of locomotion across the light/dark cycles of the 72 h recordings. This study allows a comprehensive behavioural assessment of the effects of ELSD on later life sociality and highlights subtle prairie vole behaviours. Our findings may shed light on neurodevelopmental disorders featuring sleep disruption and social deficits, such as autism spectrum disorders.

description: Faserverstärkte Sandwichstrukturen nutzen den geometrischen Versteifungseffekt durch die Erhöhung des Flächenträgheitsmoments und bieten ein hohes Potential für den ressourceneffizienten Leichtbau. Zur Optimierung der ganzheitlichen Bilanzierung eines Bauteillebens muss neben der Bauteilstruktur auch die Fertigungsmethode effizient gestaltet sein. Im Rahmen dieser Arbeit wird ein neuartiges Herstellungsverfahren – der Direct Sand-wich Composite Molding (D-SCM) Prozess – konzipiert, entwickelt und validiert. Beim D-SCM Prozess wird der Schaumdruck infolge der chemischen Reaktion von schäumendem Polyurethan (PUR) im geschlossenen Fertigungswerkzeug genutzt. Dieser wirkt aus der Kernstruktur heraus auf die benetzten, textilen Decklagen und stellt den notwendigen Prozessdruck zur Decklagenkonsolidierung bereit. Ein Alleinstellungsmerkmal des D-SCM Prozesses ist die undurchlässige Barriereschicht in Form einer thermoplastischen Polyurethan-(TPU)-Folie zwischen Schaumkern und den Decklagen. Damit kann das unkontrollierte Eintreten von Schaumporen in die Decklagen verhindert werden. Innerhalb der methodischen Prozessentwicklung werden die Viskositätseigenschaften der Harzsysteme, das Kompaktierungsverhalten der Faserstruktur und die Adhäsionseigenschaften der TPU-Grenzschicht detailliert charakterisiert. Der zeitabhängige Druckaufbau des schäumenden Polyurethans in der Kernstruktur ist entscheidend für die ein-stufige Herstellung von Sandwichstrukturen im D SCM Prozess. Infolgedessen wird der Einfluss der chemischen PUR-Formulierung und der Schaumdichte auf die Druckentwicklung untersucht und das PUR-System auf Grundlage der Materialcharakterisierungen angepasst. Durch den Einsatz von Simulations- und Modellierungsmethoden werden anschließend zielführende Prozessfenster zur einstufigen Herstellung von Sandwichstrukturen im D SCM Verfahren bestimmt. Zur Prozessvalidierung werden auf Basis der identifizierten Prozessfenster zunächst Sandwichstrukturen im D-SCM Prozess hergestellt und die Bauteile im Anschluss charakterisiert. In den Decklagen werden Faservolumengehalte bis 35 % und Porositäten kleiner 1,5 % erreicht. Die TPU-Barriereschicht verhindert den Schaumeintritt in die Decklagen zuverlässig. Bei der Analyse der Bauteileigenschaften im 3-Punkt Biegeversuch zeigt sich, dass die im D SCM Prozess erzielbaren Verbundeigenschaften maßgeblich vom Schaumkern beeinflusst werden. Dieser stellt damit eine effiziente Stellgröße bei der Einstellung der gewünschten Verbundeigenschaften dar. Die Prozessdemonstration des D SCM Verfahrens an einer 2,5D Geometrie belegt zudem, dass der erzielbare Schaum-druck zum Umformen abwickelbarer Decklagenbereiche ausreichend ist und die Erkenntnisse aus der Prozessentwicklung übertragbar sind.

description: An efficient hardware implementation for Simultaneous Localization and Mapping (SLAM) methods is of necessity for mobile autonomous robots with limited computational resources. In this paper, we propose a resource-efficient FPGA implementation for accelerating scan matching computations, which typically cause a major bottleneck in 2D LiDAR SLAM methods. Scan matching is a process of correcting a robot pose by aligning the latest LiDAR measurements with an occupancy grid map, which encodes the information about the surrounding environment. We exploit an inherent parallelism in the Rao-Blackwellized Particle Filter (RBPF) based algorithms to perform scan matching computations for multiple particles in parallel. In the proposed design, several techniques are employed to reduce the resource utilization and to achieve the maximum throughput. Experimental results using the benchmark datasets show that the scan matching is accelerated by 5.31-8.75x and the overall throughput is improved by 3.72-5.10x without seriously degrading the quality of the final outputs. Furthermore, our proposed IP core requires only 44% of the total resources available in the TUL Pynq-Z2 FPGA board, thus facilitating the realization of SLAM applications on indoor mobile robots.

description: We report on FORS2 optical spectroscopy of the black hole X-ray binary V404 Cygni, performed at the very beginning of its 2015 outburst decay, complemented by quasi-simultaneous $Swift$ X-ray and ultra-violet as well as REM near-infrared observations. Its peculiar spectrum is dominated by a wealth of emission signatures of HI, HeI, and higher ionisation species, in particular FeII. The spectral features are divided between broad red-shifted and narrow stationary varieties, the latter being emitted in the outer regions. Continuum and line variability at short time scale is high and we find Baldwin effect-like anti-correlations between the full-widths at half-maximum and equivalent widths of the broad lines with their local continua. The Balmer decrement Hα/Hβ is also abnormally large at $4.61\pm0.62$. We argue that these properties hint at the broad lines being optically thick and arising within a circumbinary component in which shocks between faster optically thick and slower optically thin regions may occur. We associate it to a nova-like nebula formed by the cooling remnant of strong accretion disc winds that turned off when the mass-accretion rate dropped following the last major flare. The FeII lines likely arise from the overlap region between this nebula and the companion star winds, whereas we favour the shocks within the nebula as responsible for the optical continuum via self-absorbed optically thin bremsstrahlung. The presence of a near-infrared excess also points towards the contribution of a strongly variable compact jet or a dusty component.

description: Research suggests that nursing facility structural characteristics are important contributors toward residents� quality of care. We use 2021 data from 220 Maryland nursing facilities to examine associations between two different quality-of-care metrics: family satisfaction and Care Compare five-star quality ratings. We used descriptive statistics to explore differences in quality metrics across facility ownership (for-profit vs. non-profit), geographic location (urban vs. rural), and resident census (1�, 61�0, and 121+). Relationships were examined across overall ratings, as well as across subdomains of the two frameworks (e.g., staffing). Family members of residents in non-profit, rural, and low-census facilities rated facilities higher. Non-profit and low-resident census facilities were more likely to be rated four or five stars, while no significant association was observed across geographic location, or interactions across structural factors. Findings emphasize the need for comprehensive quality-of-care frameworks that explore quality care across stakeholders and types of facilities.

description: A classification is given of the exceptional $\mathbb{Z}_2 \times \mathbb{Z}_2$-symmetric spaces $G/K$ by A.Kollross, where $G$ is an exceptional compact Lie group or $S\!pin(8)$, and moreover the structure of $K$ is determined as Lie algebra. In the present article, we give a pair of commuting involutive automorphisms (involutions) $\tildeσ, \tildeτ$ of $G$ concretely and determine the structure of group $G^σ \cap G^τ$ corresponding to Lie algebra $\mathfrak{g}^σ\cap \mathfrak{g}^τ$, where $G$ is an exceptional compact Lie group. Thereby, we realize exceptional $\mathbb{Z}_2 \times \mathbb{Z}_2$-symmetric spaces, globally.

description: Recently, Advanced Laser Interferometer Gravitational-wave Observatory (aLIGO) detected gravitational wave (GW) transients from mergers of binary black holes (BHs). The system may also produce a wide-angle, relativistic outflow if the claimed short GRB detected by GBM is in real association with GW 150914. It was suggested that mergers of double neutron stars (or neutron star-black hole binaries), another promising source of GW transients, also produce fast, wide-angle outflows. In this paper, we calculate the high-energy gamma-ray emission arising from the blast waves driven by these wide-angle outflows. We find that TeV emission arising from the inverse-Compton process in the relativistic outflow resulted from mergers of binary BHs similar to those in GW 150914 could be detectable by ground-based IACT telescopes such as Cherenkov Telescope Array (CTA) if the sources occur in { a dense medium with density $n > 0.3 cm^{-3}$}. For neutron star-neutron star (NS-NS) and NS-BH mergers, TeV emission from the wide-angle, mildly-relativistic outflow could be detected as well if they occur in a dense medium {with $n > 10-100 cm^{-3}$.} Thus TeV afterglow emission would be a useful probe of the environment of the GW transients, which could shed light on the evolution channels of the progenitors of GW transients.

description: This thesis is the first to provide an overview of the English book ownership of Danish and Dutch collectors, by following the circulation of books printed in England on the book markets in Denmark and the Dutch Republic between 1600 and 1720. Book auctions first took place in the Dutch Republic in the early seventeenth century, where it became common practice to print and distribute an auction catalogue to facilitate sales. In 1661, Denmark followed the Dutch example and created a second thriving European market for book auctions. The printed auction catalogues marked the beginning of a book market that became more accessible to both private owners and institutions, such as universities, and they comprise the principal source base for this thesis. The English printing industry has long been studied only from a national perspective, in which the import of books played a major role. The opposite movement, the export of English books to mainland Europe, remained underexposed. Existing studies have made use of book trade and fair catalogues to understand the circulation of English publications abroad. This study aims to add to that knowledge by looking at private book ownership. During their lifetime, library owners sourced books from all the major printing centres in Europe. Books from England formed a modest share of their collections. However, the exact size of that share and the type of books these bibliophiles collected remained unknown. This study addresses that lacuna. In addition to the contents of 192 catalogues from private owners, another 51 catalogues from booksellers and 14 institutional catalogues were inspected to see how the collections relate to one another. Private owners, some of whom had strong ties to England, took the lead and were more adventurous than booksellers or university librarians in purchasing new titles. By choosing print published in England, these private collectors from Denmark and the Dutch Republic were at the forefront of the European reading public.
Generalisations of Hecke algebras from Loop Braid Groups

description: We introduce a generalisation $LH_n$ of the ordinary Hecke algebras informed by the loop braid group $LB_n$ and the extension of the Burau representation thereto. The ordinary Hecke algebra has many remarkable arithmetic and representation theoretic properties, and many applications. We show that $LH_n$ has analogues of several of these properties. In particular we %introduce consider a class of local (tensor space/functor) representations of the braid group derived from a meld of the (non-functor) Burau representation and the (functor) Deguchi {\em et al}-Kauffman--Saleur-Rittenberg representations here called Burau-Rittenberg representations. In its most supersymmetric case somewhat mystical cancellations of anomalies occur so that the Burau-Rittenberg representation extends to a loop Burau-Rittenberg representation. And this factors through $LH_n$. Let $SP_n$ denote the corresponding quotient algebra, $k$ the ground ring, and $t \in k$ the loop-Hecke parameter. We prove the following: 1) $LH_n$ is finite dimensional over a field. 2) The natural inclusion $LB_n \rightarrow LB_{n+1}$ passes to an inclusion $SP_n \rightarrow SP_{n+1}$. 3) Over $k=\mathbb{C}$, $SP_n / rad $ is generically the sum of simple matrix algebras of dimension (and Bratteli diagram) given by Pascal's triangle. 4) We determine the other fundamental invariants of $SP_n$ representation theory: the Cartan decomposition matrix; and the quiver, which is of type-A. 5) The structure of $SP_n $ is independent of the parameter $t$, except for $t= 1$. \item For $t^2 \neq 1$ then $LH_n \cong SP_n$ at least up to rank$n=7$ (for $t=-1$ they are not isomorphic for $n>2$; for $t=1$ they are not isomorphic for $n>1$). Finally we discuss a number of other intriguing points arising from this construction in topology, representation theory and combinatorics.

description: Proton-proton (pp) collisions have been used extensively as a reference for the study of interactions of larger colliding systems at the LHC. Recent measurements performed in high-multiplicity pp and proton-lead (p-Pb) collisions have shown features that are reminiscent of those observed in lead-lead (Pb-Pb) collisions. In this context, the study of identified particle spectra and yields as a function of multiplicity is a key tool for the understanding of similarities and differences between small and large systems. We report on the production of pions, kaons, protons, $K^{0}_{\rm S}$, $Λ$, $Ξ$, $Ω$ and $K^{*0}$ as a function of multiplicity in pp collisions at $\sqrt{s}=$ 7 TeV measured with the ALICE experiment. The work presented here represents the most comprehensive set of results on identified particle production in pp collisions at the LHC. Spectral shapes, studied both for individual particles and via particle ratios as a function of $p_{\rm T}$, exhibit an evolution with charged particle multiplicity that is similar to the one observed in larger systems. In addition, results on the production of light flavour hadrons in pp collisions at $\sqrt{s}=$ 13 TeV, the highest centre-of-mass energy ever reached in the laboratory, are also presented and compared with previous, lower energy results.

description:  Landscaping is a popular industry in Dubai and there are many landscape companies to choose from. But what sets the best landscaping companies apart from the rest? The answer lies in their ability to properly manage their projects. In this blog, we will discuss how landscape companies in Dubai manage their projects properly and why it is important for them to do so. 

Planning Ahead
The first step to any successful project management is planning ahead. From creating an initial budget and timeline to outlining the scope of the project, proper planning ensures that no detail is overlooked during the course of the project. This also allows you to create realistic expectations for both yourself and your clients, as well as ensuring that all stakeholders are on board with the plan. 

Managing Resources Efficiently 
Another key element of proper project management is managing resources efficiently. Landscape companies in Dubai have access to a wide range of tools, materials, and personnel that can be used for their projects. It’s important for these companies to make sure they are using their resources effectively and efficiently by factoring in costs and availability when making decisions about which materials or personnel should be used for a particular project. 

Maintaining Quality Control 
Finally, landscape companies need to maintain quality control throughout each stage of their projects. This includes hiring qualified professionals who have experience working with plants or outdoor spaces, as well as conducting regular inspections throughout the course of the project to ensure everything meets quality standards before completion. By doing this, landscape companies in Dubai can ensure that their projects are completed successfully and exceed client expectations every time. 

Project management is an essential part of any successful business venture—especially when it comes to landscaping services in Dubai. From creating an initial budget and timeline to managing resources efficiently and maintaining quality control throughout each stage of the project, proper planning and execution can make all the difference between success and failure when it comes to completing a landscaping job on time and within budget. With careful attention paid at every step of the way, landscape companies in Dubai can ensure that they deliver exceptional results every time!
