description: Travelling Edges: An Immersed Autoethnographic and Practice-led Exploration of the Australian Bush in Art explores the effects of deep immersion in the bush on the portrayal of rural and wilderness environments. Current research into immersion in natural environments demonstrates there is “a cognitive advantage” to being immersed in bush settings that includes enhanced “higher order cognitive skills” such as creative thinking (Atchley et al., 2012, pp. 1-2). From the perspective of an artist, I argue immersed living in natural environments generates robust “emotional connections”, “higher intensity learning”, and “first hand” authentic experiences that enhance an artist’s creativity (Chaehan, n.p., 2020). Immersion in the bush is crucial to my art and provides an important reference point for this practice-led and autoethnographic research contextualised against the “societal phenomenon” shaping Australian culture (Wall, 2006, p. 1). The use of practice-led research relates to the development of my art practice which is reflective and “informed by theory” (Bolt, 2006, p. 4), thereby enabling a more intimate response to the bush as my primary art subject. To communicate the nature of this bush centred research, the title “Travelling Edges” has been used to evoke my isolation but sense of security in rural areas and the wariness I feel towards large urban centres. This project has been motivated by my lifelong connection with the bush, traceable to a mnemonic of family origins interrelated with life in and near Australian First Nations communities, with each shaping my understanding and experience as a non-Indigenous artist and informing my artistic practice.

description: The case describes the journey of Riya Grover and Lyz Swanton (MBAs from HBS and LBS respectively) who launched, scaled and sold London-based startup Feedr during the second half of 2010. Feedr introduced a sustainable solution offering nutritionally healthy food by leveraging technology to drive personalisation in choice and scale.  In Part B, we meet the founders as they set out to fundraise a second round. Feedr leveraged the 'funding buffet' by raising capital from a mix of investors; raising an investment through an equity crowdfunding campaign and completing the round with an institutional investor, the VC fund Episode 1. The case concludes with the sale of Feedr to a strategic buyer. It describes a process that started as a prospective investment from a corporate VC and ended in an outright acquisition.

Why assurance and advisory reports look the way they do: a discourse analysis of submissions to an Australian Royal Commission
Creators: name: Matthews, Sally

description: The purpose of this study was to analyse the Executive Summaries of assurance and advisory reports submitted by Professional Service Firms (PSF) as evidence to the Australian 2018 – 2019 Royal Commission into the Banking, Superannuation and Financial Services Industry. The 32 Word and PowerPoint documents in this dataset were reviews by PSFs of large corporations’ financial controls, policies and procedures and are often relied on by regulators and stakeholders to ensure the integrity and reliability of financial institutions. Following CGA principles, a variety of research methods were employed to investigate this hard to access but influential discourse community, including genre analysis, multimodal analysis and interviews. Results indicated that the Executive Summaries are a pliable and hybrid genre, made up of mainly optional stages which are sequenced in a variety of patterns to meet the writers’ surface and private purposes. Their writers collaborate with their clients to write the reports, although the tenor of the documents is impersonal and objective. Visual semiotics are used, particularly in the PowerPoint documents, however language is the main meaning making resource. These results were taken as evidence of the value of CGA in helping to investigate the discursive practices of an opaque but essential professional community.

description: The band structure and the optical conductivity of an ABA (Bernal-type) stacked graphene trilayer are calculated. It is shown that, under appropriate doping, a strong resonant peak develops in the optical conductivity, located at the frequency corresponding to approximately 1.4 times the interlayer hopping energy and caused by the 'nesting' of two nearly parabolic bands in the electronic spectrum. The intensity of this resonant absorption can be controlled by adjusting the gate voltage. The effect is robust with respect to increasing temperature.

description: Biochemical and pharmacological investigations about the effect of the antidepressant drug viloxazine (Vivalan) on catecholamine metabolism in rats led to the following results: Viloxazine exerts a dose and time dependent inhibition of monoamine oxidase activity of brain and liver mitochondrial fraction and tissue homogenates of hypothalamus, heart, liver, and adrenal glands, both in vitro and after oral and parenteral administration in vivo. Consequently, an increase in catecholamine concentrations in brain of rats could be observed after pretreatment with viloxazine. In addition brain serotonin concentrations rose and 5-hydroxy-indoleacetic acid was diminished. However, characterization of inhibition of monoamine oxidase activity by viloxazine in vitro revealed: Compared to the specific inhibitors clorgyline for MAO-A- and pargyline for MAO-B-activity, viloxazine was a very weak inhibitor both for MAO-A and MAO-B in vitro. The type of inhibition was competitive and reversible. From the presented results and the results obtained by other laboratories it is concluded that inhibition of monoamine oxidase activity by viloxazine, although clearly demonstrated in animal experiments, may not be the only mechanism for an antidepressant action of the drug in man.

description: Autonomous vehicles and robots need to operate over a wide variety of scenarios in order to complete tasks efficiently and safely. Multi-camera self-supervised monocular depth estimation from videos is a promising way to reason about the environment, as it generates metrically scaled geometric predictions from visual data without requiring additional sensors. However, most works assume well-calibrated extrinsics to fully leverage this multi-camera setup, even though accurate and efficient calibration is still a challenging problem. In this work, we introduce a novel method for extrinsic calibration that builds upon the principles of self-supervised monocular depth and ego-motion learning. Our proposed curriculum learning strategy uses monocular depth and pose estimators with velocity supervision to estimate extrinsics, and then jointly learns extrinsic calibration along with depth and pose for a set of overlapping cameras rigidly attached to a moving vehicle. Experiments on a benchmark multi-camera dataset (DDAD) demonstrate that our method enables self-calibration in various scenes robustly and efficiently compared to a traditional vision-based pose estimation pipeline. Furthermore, we demonstrate the benefits of extrinsics self-calibration as a way to improve depth prediction via joint optimization.

description: To evaluate the therapeutic value of various antihypotensive agents we investigated amezinium (AMZ; CAS 30578-37-1), dihydroergotamine (DHE; CAS 511-12-6), midodrine (MDD; CAS 42794-76-3), and oxilofrine (OXF; CAS 365-26-4) in volunteers during passive orthostasis in a randomized double-blind study against placebo (PCB). Blood pressure, heart rate, and circulating catecholamines were determined before and after i.v. injections of the mentioned agents before and during 10 min of passive orthostasis. Echocardiographic and venous plethysmographic data were obtained during resting before and after the administration of the drugs. Resting heart rate decreased after injection of PCB, AMZ, DHE, and MDD. During tilting no significant changes in heart rate could be observed. Blood pressure remained unchanged at rest and during orthostasis after all agents injected. DHE and MDD lowered circulating noradrenaline. Echocardiographic parameters were changed after administration of AMZ (increase in stroke volume index (SVI) and ejection fraction (EF)), MDD (increase in enddiastolic volume index and SVI), and OXF (increase in SVI, EF, and cardiac index). The venous capacity of the lower left leg was only significantly decreased after injection of DHE, indicating an increased venous tone of the leg veins. The observed changes in sympathetic and cardiovascular parameters are in agreement with their sympathomimetic actions and allow a differential therapeutic classification: DHE and MDD are suitable agents for patients with sympathotonic orthostatic reaction; if asympathotonic orthostatic reaction occurs MDD, AMX and OXF should be recommended to those patients.

description: Entanglement plays an important role in quantum communication, algorithms, and error correction. Schmidt coefficients are correlated to the eigenvalues of the reduced density matrix. These eigenvalues are used in Von Neumann entropy to quantify the amount of the bipartite entanglement. In this paper, we map the Schmidt basis and the associated coefficients to quantum circuits to generate random quantum states. We also show that it is possible to adjust the entanglement between subsystems by changing the quantum gates corresponding to the Schmidt coefficients. In this manner, random quantum states with predefined bipartite entanglement amounts can be generated using random Schmidt basis. This provides a technique for generating equivalent quantum states for given weighted graph states, which are very useful in the study of entanglement, quantum computing, and quantum error correction.

description: We perform a set of 38 numerical simulations of equal-mass BH binaries in a configuration where the BH spins in the binary are equal in both magnitude and direction, to study precession effects. We vary the initial direction of the total spin S with respect to the orbital angular momentum L, covering the 2 dimensional space of orientation angles with 38 configurations consisting of 36 configurations distributed in the azimuthal angle phi and polar angle theta, and two configurations on the poles. In all cases, we set the initial dimensionless BH spins to 0.8. We observe that during the late-inspiral stage, the total angular momentum of the system J remains within 5 deg of its original direction, with the largest changes in direction occurring when the spins are nearly counter-aligned with the orbital angular momentum. We also observe that the angle between S and L is nearly conserved during the inspiral phase. These two dynamical properties allow us to propose a new phenomenological formula for the final mass and spin of merged BHs in terms of the individual masses and spins of the progenitor binary at far separations. We determine coefficients of this formula (in the equal-mass limit) using a least-squares fit to the results of this new set of 38 runs, an additional set of five new configurations with spins aligned/counteraligned with the orbital angular momentum, and over 100 recent simulations. We find that our formulas reproduce the remnant mass and spin of these simulations to within a relative error of 2.5%. We discuss the region of validity of this dynamical picture for precessing unequal-mass binaries. Finally, we perform a statistical study to see the consequence of this new formula for distributions of spin-magnitudes and remnant masses with applications to BH-spin distributions and gravitational radiation in cosmological scenarios involving several mergers.

description: In two groups of volunteers pharmacological parameters of the antihypotensive drug midodrine have been investigated. The first group of 12 male healthy volunteers received 2.5 mg midodrine hydrochloride intravenously, as drinking solution or as tablet according to a randomized cross-over design. Plasma and urine samples were analyzed for midodrine and its main metabolite ST 1059 by high-performance liquid chromatography. The mean maximum concentration in plasma for midodrine was 10 ng/ml 20-30 min after oral administration, for ST 1059 5 ng/ml after 1 h. Midodrine was eliminated with a terminal half-life of 0.5 h, ST 1059 with a half-life of 3 hrs. The mean area under the plasma-level vs. time curve (AUC) of ST 1059 after administration of 2.5 mg midodrine i.v. was 28.7 ng x h/ml, and similar for the other formulations which are considered to be bioequivalent. In a second group of 15 volunteers with postural hypotension midodrine (M) as alpha-sympathomimetic drug and oxilofrine (O) as beta-sympathomimetic drug was given i.v. in a randomized double blind study against placebo (P). Blood pressure (BP), heart rate (HR) and circulating catecholamines (CA) were determined before and after injections of the drugs as well as before and during 10 min of tilting. Echocardiographic parameters were obtained at rest before and after the administration of the drugs. Blood pressure remained unchanged at rest and during orthostasis after all agents injected. After oral administration of midodrine heart rate was decreased and systolic blood pressure increased significantly and dose-dependently. M lowered circulating noradrenaline.(ABSTRACT TRUNCATED AT 250 WORDS)

description: This paper introduces a framework for state estimation on a humanoid robot platform using only common proprioceptive sensors and knowledge of leg kinematics. The presented approach extends that detailed in [1] on a quadruped platform by incorporating the rotational constraints imposed by the humanoid's flat feet. As in previous work, the proposed Extended Kalman Filter (EKF) accommodates contact switching and makes no assumptions about gait or terrain, making it applicable on any humanoid platform for use in any task. The filter employs a sensor-based prediction model which uses inertial data from an IMU and corrects for integrated error using a kinematics-based measurement model which relies on joint encoders and a kinematic model to determine the relative position and orientation of the feet. A nonlinear observability analysis is performed on both the original and updated filters and it is concluded that the new filter significantly simplifies singular cases and improves the observability characteristics of the system. Results on simulated walking and squatting datasets demonstrate the performance gain of the flat-foot filter as well as confirm the results of the presented observability analysis.

description: Clarithromycin is a new macrolide that has a longer half-life than erythromycin and is claimed to reach higher tissue concentrations. We aimed to investigate whether, following oral administration, the drug and its 14-hydroxy metabolite reach levels in lung tissue that are likely to be clinically effective against common respiratory pathogens. Ten patients undergoing diagnostic bronchoscopy received seven doses of clarithromycin, 500 mg b.i.d. orally. Bronchoscopy was performed at a mean time of 4.25 h after the last dose. At bronchoscopy, bronchial biopsies and bronchoalveolar lavage were performed. Clarithromycin and its 14-OH metabolite were measured in serum, bronchial biopsies, epithelial lining fluid (ELF) and alveolar cells. Mean levels of clarithromycin were 4.0 mg.l-1 in serum, 16.8 mg.kg in bronchial biopsies, 20.5 mg.l-1 in ELF and 372.7 mg.l-1 in alveolar cells. The equivalent levels of 14-OH metabolite were 0.7, 2.7, 1.9 and 38.6 mg.l-1, respectively. We conclude that there is considerable concentration of clarithromycin and its 14-OH metabolite in alveolar cells, and to a lesser extent in bronchial tissue and ELF; this implies efficacy against susceptible organisms at these sites.

The tablet formulations showed nearly identical pharmacokinetic parameters and were bioequivalent. The mean maximum serum concentration was 4.7 micrograms/ml, achieved after 2.1 h. The serum half-live was 1.2-1.4 h, the area under the serum concentration-time curve was 14.3-14.4 micrograms/ml.h and the urinary recovery of unchanged cefuroxime was 54%. The bioavailability of cefuroxime after administration of cefuroxime axetil in aqueous suspension was lower, but bio-inequivalence was not demonstrated.

description: In the past two decades, esports has proliferated and attracted public and research attention. Researchers have primarily focused on non-verbal communication in esports, such as pings, which is integral to effective esports communication but can be distracting if used ineffectively. However, there has been little examination of verbal communication within teams. This study is the first to analyze how esports athletes use verbal communication within teams during a high-stakes competition. This exploratory qualitative analysis focuses on the content of intrateam verbal communication and explores its role in effective performance. Researchers verbatim transcribed a publicly accessible video of a high-stakes esports competition that included full audio of intrateam communication. Subsequently, three researchers used content analysis and open coding to identify emergent themes and patterns in the transcription. Researchers identified five emergent themes: emotional feedback, decision-making communication, points of emphasis, moments of uncertainty, and confirmations. Each theme contained several subthemes which were interwoven throughout in-game communication. The relationship between subthemes appeared to have a bidirectional relationship with in-game performance. Results highlight the importance of effective communication, team roles, and leadership in esports.
The Economic Value of Streams for Fishing

Publisher: name: Kentucky Water Resources Research Institute, University of Kentucky
Year: 1970

description: Abstract:
The pressures of urbanization and industrialization are gradually destroying stream fishing sites while at the same time producing an increased demand to serve a greater population. Reservoir construction is one cause behind the diminishing availability of stream fisheries. The recreational value of the stream fishery lost should be deducted from the value gained through reservoir recreation in estimating net benefits for economic justification. This study utilized information collected from 3321 stream fishermen to derive a method and the necessary empirical coefficients for predicting the number and economic value of the average annual fisherman-days enjoyed along average streams throughout Kentucky.
The locations of the home and the fishing site were noted for each fisherman interviewed. The collected data were fitted to a gravity-type model for predicting annual fishing use from the magnitude and distribution of the surrounding population. The unit value of a fisherman-day was estimated from the observed willingness of fishermen to travel to find a suitable fishing site and an. estimated cost of travel. The unit value was found to vary as functions of geographical location within Kentucky and stream order. The annual number of fisherman-days was found to vary with stream order.
The method when applied to a reservoir which inundated 75.6 miles of streams from the second through the fifth order in Western Kentucky deduced an average annual recreational value lost of $10,410 at an average value of $1.83 per fisherman-day. Annual values per mile ranged from 1.9 fisherman days and $2.60 on second order streams to 221 fisherman-days and $395 on fifth order streams.

Anomalous diffusions induced by enhancement of memory

Year: 2014
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: We introduced simple microscopic non-Markovian walk models which describe underlying mechanism of anomalous diffusions. In the models, we considered the competitions between randomness and memory effects of previous history by introducing the probability parameters. The memory effects were considered in two aspects, one is the perfect memory of whole history and the other is the latest memory improved with time. In the perfect memory model superdiffusion was induced with the relation the Hurst exponent $H$ to the controlling parameter $p$ as $H=p$ for $p>1/2$. While in the latest memory enhancement models, anomalous diffusions involving both superdiffusion and subdiffusion were induced with the relations $H=(1+α)/2$ and $H=(1-α)/2$ for $0 \le α\le 1$ where $α$ is the parameter controlling the degree of the latest memory enhancement. Also we found that although the latest memory was only considered, the memory improved with time results in the long-range correlations between steps and the correlations increases as time goes. Thus we suggest the memory enhancement as a novel key origin describing anomalous diffusions.

description: There is considerable evidence to suggest that the field equations of gravity have the same status as, say, the equations describing an emergent phenomenon like elasticity. In fact, it is possible to derive the field equations from a thermodynamic variational principle in which a set of normalized vector fields are varied rather than the metric. We show that this variational principle can arise as a low energy ($L_P = (G\hbar/c^3)^{1/2} \to 0$) relic of a plausible nonperturbative effect of quantum gravity, viz. the existence of a zero-point-length in the spacetime. Our result is nonperturbative in the following sense: If we modify the geodesic distance in a spacetime by introducing a zero-point-length, to incorporate some effects of quantum gravity, and take the limit $L_P \to 0$ of the Ricci scalar of the modified metric, we end up getting a nontrivial, leading order ($L_P$ - independent) term. \textit{This term is identical to the expression for entropy density of spacetime used previously in the emergent gravity approach.} This reconfirms the idea that the microscopic degrees of freedom of the spacetime, when properly described in the full theory, could lead to an effective description of geometry in terms of a thermodynamic variational principle. This is conceptually similar to the emergence of thermodynamics from mechanics of, say, molecules. The approach also has important implications for cosmological constant which are briefly discussed.

description: We propose an all optical ultrafast method to highly magnetize general quantum magnets using a circularly polarized terahertz laser. The key idea is to utilize a circularly polarized laser and its chirping. Through this method, one can obtain magnetization curves of a broad class of quantum magnets as a function of time even without any static magnetic field. We numerically demonstrate the laser-induced magnetization process in realistic quantum spin models and find a condition for the realization. The onset of magnetization can be described by a many-body version of Landau-Zener mechanism. In a particular model, we show that a plateau state with topological properties can be realized dynamically.

description: We perform the resummation of soft-gluon emissions for squark and gluino production at next- to-next-to-leading-logarithmic (NNLL) accuracy. We include also the one-loop hard matching coefficients as well as Coulomb corrections to second order, using Mellin-moment methods. We study the characteristics of this resummation in detail for a centre-of-mass (CM) energy of 8 TeV at the LHC, and for squark and gluino masses up to 2.5 TeV. We find significant enhancing effects for all four processes of squark- and gluino-pair production. Scale dependence is generally reduced compared to NLL resummation, except for gluino-pair production where we find a moderate enhancement.

description: We have developed a simulation technique that uses non-linear finite element analysis and elastic fracture mechanics to compute physically plausible motion for three-dimensional, solid objects as they break, crack, or tear. When these objects deform beyond their mechanical limits, the system automatically determines where fractures should begin and in what directions they should propagate. The system allows fractures to propagate in arbitrary directions by dynamically restructuring the elements of a tetrahedral mesh. Because cracks are not limited to the original element boundaries, the objects can form irregularly shaped shards and edges as they shatter. The result is realistic fracture patterns such as the ones shown in our examples. This paper presents an overview of the fracture algorithm, the details are presented in our ACM SIGGRAPH 1999 and 2002 papers.

description: Two-dimensional electron gases (2DEGs) in SrTiO$_3$ have become model systems for engineering emergent behaviour in complex transition metal oxides. Understanding the collective interactions that enable this, however, has thus far proved elusive. Here we demonstrate that angle-resolved photoemission can directly image the quasiparticle dynamics of the $d$-electron subband ladder of this complex-oxide 2DEG. Combined with realistic tight-binding supercell calculations, we uncover how quantum confinement and inversion symmetry breaking collectively tune the delicate interplay of charge, spin, orbital, and lattice degrees of freedom in this system. We reveal how they lead to pronounced orbital ordering, mediate an orbitally-enhanced Rashba splitting with complex subband-dependent spin-orbital textures and markedly change the character of electron-phonon coupling, co-operatively shaping the low-energy electronic structure of the 2DEG. Our results allow for a unified understanding of spectroscopic and transport measurements across different classes of SrTiO$_3$-based 2DEGs, and yield new microscopic insights on their functional properties.

description: Clarithromycin and its metabolite, 14-hydroxy-clarithromycin are active against a wide range of respiratory pathogens. Antibiotics generally penetrate poorly into respiratory secretions which may therefore continue to harbour bacteria following bronchial infection. We have studied sputum and serum concentrations of clarithromycin and 14-hydroxy-clarithromycin in eight patients with idiopathic bronchiectasis without infective exacerbations (five male, three female; mean age 53.3 years). Oral single dose administration of 250 or 500 mg clarithromycin, separated by at least 6 days, was given to each patient. Serum and sputum samples were collected (the latter by physiotherapy at 0, 1, 2, 4, 8, 24 and 0, 4, 8 and 24 h respectively after administration of each dose. Serum sol phase was obtained by high speed centrifugation and concentrations of clarithromycin and 14-hydroxy-clarithromycin were determined by high performance liquid chromatography. Serum Cmax for clarithromycin and 14-hydroxy-clarithromycin were 1.20 mg/L (3 h) and 0.37 mg/L (3.1 h) for clarithromycin (250 mg)) and were 2.78 mg/L (2.5 h) and 0.68 mg/L (2.6 h) for clarithromycin (500 mg) respectively. Sputum Cmax for clarithromycin and 14-hydroxy-clarithromycin were 0.52 mg/L (5 h) and 0.30 mg/L (5.5 h) for clarithromycin (250 mg) and were 1.59 mg/L (5 h) and 0.47 mg/L (5.5 h) for clarithromycin (500 mg) respectively. The sputum/serum percentage ratios at Cmax (sputum) for clarithromycin and 14-hydroxy-clarithromycin were 74.3% and 113.9% (250 mg) and 94.7% and 99.9% (500 mg) respectively. We conclude that oral administration of clarithromycin to patients with bronchiectasis results in rapid penetration into respiratory mucus with persistent drug concentrations that exceed its MIC for many respiratory pathogens.

description: We report measurements of Shubnikov-de Haas oscillations in the giant Rashba semiconductor BiTeI under applied pressures up to $\sim 2\,\mathrm{GPa}$. We observe one high frequency oscillation at all pressures and one low frequency oscillation that emerges between $\sim 0.3-0.7\,\mathrm{GPa}$ indicating the appearance of a second small Fermi surface. BiTeI has a conduction band bottom that is split into two sub-bands due to the strong Rashba coupling, resulting in a `Dirac point'. Our results suggest that the chemical potential starts below the Dirac point in the conduction band at ambient pressure and moves upward, crossing it as pressure is increased. The presence of the chemical potential above this Dirac point results in two Fermi surfaces. We present a simple model that captures this effect and can be used to understand the pressure dependence of our sample parameters. These extracted parameters are in quantitative agreement with first-principles calculations and other experiments. The parameters extracted via our model support the notion that pressure brings the system closer to the predicted topological quantum phase transition.

description: In January 2013, Irish Tour Professional Golfer, Paul McGinley was named as Captain of Team Europe for the 2014 Ryder Cup in Gleneagles, Scotland. Across his career, McGinley had both played himself in the Ryder Cup as well as acted as Vice Captain in two successful tournaments for the Team Europe. Being the Captain, however, was a different game. This case traces McGinley's team strategy and demonstrates his leadership as he moulded 12 players from different European countries together into an effective team, in only a few days. He faced numerous challenges including diverse European nationalities, golf being an individual rather than a team sport, that he would only know who was on his team a few weeks before the Ryder Cup, and then that the players would only be 'together' to train four days before the actual tournament began. As well as these, Team Europe were the favourites and would be playing in Europe. McGinley knew that wasns'st an easy position to play from, particularly when the US were fielding a very strong team that year. Expectations were running high. Even during the competition, there were upheavals that McGinley had to deal with.

A tale of (sixty) two cities

description: In today’s globalized knowledge economy, technological knowledge plays an increasingly important role. Nowadays, cities and clusters cannot rely exclusively on local knowledge sources, but they need to combine local with complementary geographically distant (trans-local) knowledge sources. This dissertation contributes to the literature on the changing geographic composition of knowledge connections, and the complementarity of distant and local connections. We do this by providing a more detailed picture of how the spatial distribution of these connections is changing, and how they interact with one another across a mix of developed and developing country cities. In particular, we look at 62 cities to see how the geographic structure of their knowledge sourcing has been changing, both at the level of city dyads and in the overall structure of the worldwide knowledge network between cities. Using US patent citation data for patents invented in these 62 cities worldwide, our first study explores the nature of the association between local, trans-local and international citations. Our results show that in all cities there is a significant association between international and local citations, and that an increase in international citations leads to an increase in local connections. We also find that this effect is accentuated in highly innovative cities when compared to relatively lower innovative cities in our dataset. Our second study looks at dyadic relationships for all possible city pairs in our city dataset, and examines the determinants of the level of knowledge outflows and knowledge inflows between them. Our results show that knowledge sourcing patterns between individual cities have varied with the extent of their co-specialization of activities, their relative position in the international knowledge network and their degree of engagement with general purpose technologies. Using social network analysis techniques, we construct a unidirectional network of cities in our third study, since backward citations point in just one direction to prior knowledge sources. We observe how this network changes during our time period both in the aggregate and at the level of five selected sectors. The nodes in our network represent cities while the edges represent citations from one city to another. We calculate network statistics such as degree strength and eigenvector centrality to determine which cities have gained influence over time and which cities have become relatively less important. We find some developing cities have gained substantial influence over time especially in the network of patents in the ICT and other electrical equipment technological fields.

description: We apply color-spin and flavor-spin quark-quark interactions to the meson and baryon constituent quarks, and calculate constituent quark masses, as well as the coupling constants of these interactions. The main goal of this paper was to determine constituent quark masses from light and open bottom hadron masses, using the fitting method we have developed and clustering of hadron groups. We use color-spin Fermi-Breit (FB) and flavor-spin Glozman-Riska (GR) hyperfine interaction (HFI) to determine constituent quark masses (especially $b$ quark mass). Another aim was to discern between the FB and GR HFI because our previous findings had indicated that both interactions were satisfactory. Our improved fitting procedure of constituent quark masses showed that on average color-spin (Fermi-Breit) hyperfine interaction yields better fits. The method also shows the way how the constituent quark masses and the strength of the interaction constants appear in different hadron environments.
