description: Geometry, design, and processing in addition to the thermoelectric material properties have a significant influence on the economic efficiency and performance of thermoelectric generators (TEGs). While conventional BULK TEGs are elaborate to manufacture and allow only limited variations in geometry, printed TEGs are often restricted in their application and processing temperature due to the use of organic materials. In this work, a proof-of-concept for fabricating modular, customizable, and temperature-stable TEGs is demonstrated by applying an alternative laser process. For this purpose, low temperature cofired ceramics substrates were coated over a large area, freely structured and cut without masks by a laser and sintered to a solid structure in a single optimized thermal post-processing. A scalable design with complex geometry and large cooling surface for application on a hot shaft was realized to prove feasibility. Investigations on sintering characteristics up to a peak temperature of 1173 K, thermoelectric material properties and temperature distribution were carried out for a Ca3Co4O9/Ag-based prototype and evaluated using profilometer, XRD, and IR measurements. For a combined post-processing, an optimal sintering profile could be determined at 1073 K peak temperature with a 20 min holding time. Temperature gradients of up to 100 K could be achieved along a thermocouple. A single TEG module consisting of 12 thermocouples achieved a maximum power of 0.224 μW and open-circuit voltage of 134.41 mV at an average hot-side temperature of 413.6 K and temperature difference of 106.7 K. Three of these modules combined into a common TEG with a total of 36 thermocouples reached a maximum power of 0.58 K and open-circuit voltage of 319.28 mV with a lesser average hot-side temperature of 387.8 K and temperature difference of 83.4 K.

description: In the realm of artificial intelligence (AI), copyright infringement refers to the unauthorised usage, reproduction, distribution, or adaptation of copyrighted materials by AI systems or technologies without the required consent from copyright holders. Artificial intelligence (AI) has played a vital role in transforming many industries, such as content creation. With the escalating capabilities of AI to produce creative works, the line between human-authored and AI-generated content is increasingly blurred. This necessitates a review of the conventional copyright structures. Ownership, authorship, and liability questions have emerged as AI systems become more proficient in producing creative content. This abstract, aims to illuminate the complex interplay between AI creativity and copyright protection by examining the developing arena of AI-produced content and its linkages with current copyright laws. This research paper scrutinises the multifaceted issue of copyright infringement in AI, examining legal frameworks, ethical considerations, technological challenges, and potential solutions to guarantee a peaceful coexistence between AI and copyright. This study emphasizes the critical requirement for adaptable legal, technological, and ethical frameworks that facilitate a peaceful symbiosis between AI innovation and the safeguard of creative rights.

description: The current limits for fourth generation quarks allows to expect their mass of the order of 500 GeV. In this mass region for quark-anti-quark pair the additional Yukawa-type attraction due to Higgs mechanism is expected to emerge. This Higgs induced attraction greatly exceeds strong interaction between quarks and leads to the formation of bound states in both colour octet $S^{(8)}$ and singlet $S^{(1)}$ states. In the key of recent works on significance of colour octet channel for production of colour singlet state of fourth generation $Q\bar{Q}$ we calculated the binding energies for both octet and singlet states. Such attraction localizes quarks in extremely small area. Hence colour octet pair of fourth generation quarks can form the "nucleus" and together with colour neutralizing light particle that is captured by strong interaction in orbit around the nucleus, create particle, similar by its structure to Deuterium.

description: On 9 June 2020, the European Commission announced that it is bringing an infringement procedure against Germany because of the PSPP judgment of its Federal Constitutional Court. On 5 May 2020 the German Court had declared a ruling by the European Court of Justice ultra vires and therefore not legally binding on Germany. In this policy position, Thu Nguyen argues that the Commission is right to initiate an infringement procedure against Germany: It is a matter of principle and a signal that the Commission, as the guardian of the Treaties, will not accept breaches of EU Treaty obligations, no matter the member state or authority in breach of EU law.

description: We resolve 182 individual giant molecular clouds (GMCs) larger than 2.5 $\times$ 10$^{5}$ \Msun in the inner disks of five large nearby spiral galaxies (NGC 2403, NGC 3031, NGC 4736, NGC 4826, and NGC 6946) to create the largest such sample of extragalactic GMCs within galaxies analogous to the Milky Way. Using a conservatively chosen sample of GMCs most likely to adhere to the virial assumption, we measure cloud sizes, velocity dispersions, and $^{12}$CO (J=1-0) luminosities and calculate cloud virial masses. The average conversion factor from CO flux to H$_{2}$ mass (or \xcons) for each galaxy is 1-2 \xcounits, all within a factor of two of the Milky Way disk value ($\sim$2 \xcounits). We find GMCs to be generally consistent within our errors between the galaxies and with Milky Way disk GMCs; the intrinsic scatter between clouds is of order a factor of two. Consistent with previous studies in the Local Group, we find a linear relationship between cloud virial mass and CO luminosity, supporting the assumption that the clouds in this GMC sample are gravitationally bound. We do not detect a significant population of GMCs with elevated velocity dispersions for their sizes, as has been detected in the Galactic center. Though the range of metallicities probed in this study is narrow, the average conversion factors of these galaxies will serve to anchor the high metallicity end of metallicity-\xco trends measured using conversion factors in resolved clouds; this has been previously possible primarily with Milky Way measurements.

description: Large, high-energy ($E>100$ GeV) cosmic neutrino telescopes are now quite mature. IceCube, for example, observes about 50,000 well-reconstructed single atmospheric neutrino events/year, with energies above 100 GeV. Although the neutrino detection probability is small, current detectors are large enough so that it is possible to detect two neutrinos from the same cosmic-ray interaction. In this paper, we calculate the expected rate of double-neutrino interactions from a single cosmic-ray air shower. The rate is small, about 0.07 events/year for a 1 km$^3$ detector like IceCube, with only a small dependence on the assumed cosmic-ray composition and hadronic interaction model. For a larger detector, like the proposed KM3Net, the rate is about 0.8 events/year, a rate that should be easily observable. These double neutrino interactions are the major irreducible background to searches of pairs of particles produced in supersymmetric neutrino or cosmic-ray air-shower interactions. Other standard-model backgrounds are considered, and found to be small.

description: The Galaxy And Mass Assembly Survey (GAMA) has now been operating for almost 5 years gathering spectroscopic redshifts for five regions of sky spanning 300 sq degrees in total to a depth of r<19.8 mag. The survey has amassed over 225,000 redshifts making it the third largest redshift campaign after the SDSS and BOSS surveys. The survey has two novel features that set it apart: (1) complete and uniform sampling to a fixed flux limit (r<19.8 mag) regardless of galaxy clustering due to multiple-visits to each sky region, enabling the construction of high-fidelity catalogues of groups and pairs, (2) co-ordination with diverse imaging campaigns which together sample an extremely broad range along the electro-magnetic spectrum from the UV (GALEX) through optical (VST KIDs), near-IR (VISTA VIKING), mid-IR (WISE), far-IR (Herschel-Atlas), 1m (GMRT), and eventually 20cm continuum and rest-frame 21cm line measurements (ASKAP DINGO). Apart from the ASKAP campaign all multi-wavelength programmes are either complete or in the final stages of observations and the UV-far-IR data are expected to be fully merged by the end of 2013. This article provides a brief flavour of the coming panchromatic database which will eventually include measurements or upper-limits across 27 wavebands for 380,000 galaxies. GAMA DR2 is scheduled for the end of January 2013.

description: Let $k[X]=k[x_0,...,x_{n-1}]$ and $k[Y]=k[y_0,...,y_{n-1}]$ be the polynomial rings in $n\geqslant 3$ variables over a field $k$ of characteristic zero containing the $n$-th roots of unity. Let $d$ be the cyclotomic derivation of $k[X]$, and let $Δ$ be the factorisable derivation of $k[Y]$ associated with $d$, that is, $d(x_j)=x_{j+1}$ and $Δ(y_j)=y_j(y_{j+1}-y_j)$ for all $j\in\mathbb Z_n$. We describe polynomial constants and rational constants of these derivations. We prove, among others, that the field of constants of $d$ is a field of rational functions over $k$ in $n-\f(n)$ variables, and that the ring of constants of $d$ is a polynomial ring if and only if $n$ is a power of a prime. Moreover, we show that the ring of constants of $Δ$ is always equal to $k[v]$, where $v$ is the product $y_0... y_{n-1}$, and we describe the field of constants of $Δ$ in two cases: when $n$ is power of a prime, and when $n=p q$.
Two-mode effective interaction in a double-well condensate

description: We investigate the origin of a disagreement between the two-mode model and the exact Gross-Pitaevskii dynamics applied to double-well systems. In general this model, even in its improved version, predicts a faster dynamics and underestimates the critical population imbalance separating Josephson and self-trapping regimes. We show that the source of this mismatch in the dynamics lies in the value of the on-site interaction energy parameter. Using simplified Thomas-Fermi densities, we find that the on-site energy parameter exhibits a linear dependence on the population imbalance, which is also confirmed by Gross-Pitaevskii simulations. When introducing this dependence in the two-mode equations of motion, we obtain a reduced interaction energy parameter which depends on the dimensionality of the system. The use of this new parameter significantly heals the disagreement in the dynamics and also produces better estimates of the critical imbalance.

description: We solve the Killing spinor equations for all near-horizon IIB geometries which preserve at least one supersymmetry. We show that generic horizon sections are 8-dimensional almost Hermitian spin${}_c$ manifolds. Special cases include horizon sections with a $Spin(7)$ structure and those for which the Killing spinor is pure. We also explain how the common sector horizons and the horizons with only 5-form flux are included in our general analysis. We investigate several special cases mainly focusing on the horizons with constant scalars admitting a pure Killing spinor and find that some of these exhibit a generalization of the 2-SCYT condition that arises in the horizons with 5-form fluxes only. We use this to construct new examples of near-horizon geometries with both 3-form and 5-form fluxes.

description: Ab initio calculations have been used to derive the elastic constants, equation of state and free energy of NaCl-, KOH-, and CsCl-type structures of AgBr. The elastic constants have been derived by the stress-strain relation. The shear elastic constants $C_{44}$ has proven to be exceptionally soft. We have found that at temperature T=0 the phase transition from the low pressure NaCl-type to the high-pressure CsCl-type structure goes over a monoclinic KOH-type structure. The free energy comparison indicates that the monoclinic phase ranges from 8 to 35 GPa.

We show that different systems having the same zero-field energy spectrum exhibit strong differences in their orbital magnetic response at zero energy, ranging from diamagnetism (graphene) to paramagnetism (dice lattice). A lattice model is introduced which interpolates continuously between these two limits. This striking behavior is related to a Berry phase varying continuously from pi to 0. These predictions could be tested with cold atoms in an optical lattice

description: The indirect, charge-carrier mediated coupling between localized magnetic moments is studied for graphene nanoflakes of triangular shape and zig-zag edge. The characteristic feature of such nanoflakes is the presence of a shell of zero-energy states in the electronic spectrum. The tight-binding Hamiltonian supplemented with a Hubbard term is used for electronic structure calculations. The indirect RKKY (Ruderman-Kittel-Kasuya-Yosida) coupling energy is derived from the total electronic energy of the system in a non-perturbative way. The attention is focused on the on-site and plaquette impurities situated along the edge. The charge doping is also taken into account. It is found that the zero-energy states may give rise to a coupling mechanism which is describable by a first-order perturbation calculus and can yield robust indirect coupling of both ferro- and antiferromagnetic character, which dominates ovet the usual RKKY mechanism. The numerical results obtained emphasize the importance of the Hubbard term and the effect of the charge doping on the coupling.

Therefore, to minimize the interaction we impose $L_1$ norm restrictions on the control pulses. In order to efficiently solve this optimization problem we employ the BFGS algorithm. We use three different functions as the derivative of the $L1$ norm of control pulses: the signum function, a fractional derivative $\frac{\dd^α|x|}{\dd x^α}$, where $0

description: We present a general overview and the first results of the SUMO project (a SUrvey of Multiple pOpulations in Globular Clusters). The objective of this survey is the study of multiple stellar populations in the largest sample of globular clusters homogeneously analysed to date. To this aim we obtained high signal-to-noise (S/N>50) photometry for main sequence stars with mass down to ~0.5 M_SUN in a large sample of clusters using both archival and proprietary U, B, V, and I data from ground-based telescopes. In this paper, we focus on the occurrence of multiple stellar populations in twenty three clusters. We have defined a new photometric index cubi= (U-B)-(B-I), that turns out to be very effective for identifying multiple sequences along the red giant branch (RGB). We found that in the V-cubi diagram all clusters presented in this paper show broadened or multimodal RGBs, with the presence of two or more components. We found a direct connection with the chemical properties of different sequences, that display different abundances of light elements (O, Na, C, N, and Al). The cubi index is also a powerful tool to identify distinct sequences of stars along the horizontal branch and, for the first time in the case of NGC104 (47 Tuc), along the asymptotic giant branch. Our results demonstrate that i) the presence of more than two stellar populations is a common feature among globular clusters, as already highlighted in previous work; ii) multiple sequences with different chemical contents can be easily identified by using standard Johnson photometry obtained with ground-based facilities; iii) in the study of GC multiple stellar populations the cubi index is alternative to spectroscopy, and has the advantage of larger statistics.

description: Management development requires an investment of time and money and like other forms of investment, should be justified on the basis of return from that investment. Rising costs have not deterred organisations from increasing their investments in this activity. However, at least in the literature, there is little conclusive evidence of the contributions of management development to corporate profitability. The purpose of the present study was to obtain an in-depth understanding of evaluation approaches employed in leading Australian business organisations to establish the contributions of management development to the attainment of corporate goals. An exploratory-descriptive research design was employed to elicit human resource practitioners' perceptions and experiences. Data collection included a questionnaire survey of 50 leading companies, in-depth semi-structured interviews of senior human resource practitioners responsible for management development in 10 of those organisations, and extensive document analysis. The study found that evaluation was based mainly on immediate reactions and feedback from participants some time after the programs, and focused almost entirely on program design and implementation and not on the effects of the management development activities on manager performance and the achievement of corporate goals. The main contributory factor to the lack of impact evaluation was found to be a lack of requisite evaluation expertise. A number of factors emerge as crucial to an effective evaluation process. First, it is essential for all stakeholders in management development to upgrade their knowledge of evaluation theory. Second, effective evaluation can occur only if there is a strong culture of evaluation. Third, there is need for greater emphasis on the integration of qualitative and quantitative evaluation procedures, and to make the program participants and their line managers key players in the evaluation process. Effectiveness in management development evaluation practices can be attained through Multi-Faceted Evaluation which facilitates ongoing generation of quantitative and qualitative evaluative data by all key stakeholders via multiple formal and informal data collection techniques for use by the stakeholders themselves, researchers and other interested parties

description: We carry out a series of numerical simulations of viscous accretion flows having a reasonable spatial distribution of the viscosity parameter. We add the power-law cooling throughout the flow. We show that, in agreement with the theoretical solutions of viscous transonic flows, matter having the viscosity parameter above a critical value becomes a Keplerian disk while matter having lesser viscosity remains a low angular momentum, sub-Keplerian flow. The latter component produces centrifugal pressure supported shock waves. Thus, for instance, a flow having sufficiently high viscosity on the equatorial plane and low viscosity above and below, would produce a Two Component Advective Flow (TCAF) where a Keplerian disk is surrounded by a rapidly infalling sub-Keplerian halo. We find that the post- shock region of the relatively cooler Keplerian disk is evaporated and the overall configuration is quite stable. This agrees with the theoretical model with two components which attempt to explain the spectral and timing properties of black hole candidates.

description: In this paper we present a single-soliton two-component cellular automata (CA) model of waves as mobile self-localizations, also known as: particles, waves, or gliders; and its version with memory. The model is based on coding sets of strings where each chain represents a unique mobile self-localization. We will discuss briefly the original soliton models in CA proposed with {\it filter automata}, followed by solutions in elementary CA (ECA) domain with the famous universal ECA {\it Rule 110}, and reporting a number of new solitonic collisions in ECA {\it Rule 54}. A mobile self-localization in this study is equivalent a single soliton because the collisions of these mobile self-localizations studied in this paper satisfies the property of solitonic collisions. We also present a specific ECA with memory (ECAM), the ECAM Rule $ϕ_{R9maj:4}$, that displays single-soliton solutions from any initial codification (including random initial conditions) for a kind of mobile self-localization because such automaton is able to adjust any initial condition to soliton structures.

description: An abstract mathematical concept of fractal organization of certain complex objects received significant attention in astrophysics during last decades. The concept evolved into a broad field including multi-fractality and intermittency, percolation theory, self-organized criticality, theory of catastrophes, etc. Such a strong mathematical and physical approach provide new possibilities for exploring various aspects of astrophysics. In particular, in the solar and stellar magnetism, multi-fractal properties of magnetized plasma turned to be useful for understanding burst-like dynamics of energy release events, conditions for turbulent dynamo action, nature of turbulent magnetic diffusivity, and even the dual nature of solar dynamo. In this review, I will briefly outline how the ideas of multi-fractality are used to explore the above mentioned aspects of solar magnetism.

A Phenomenological Evaluation of Organisational Health and Growth of SMEs In Nigeria

Publisher: name: Leeds Beckett University
Year: 2022
Subjects: Uncategorized

description: The focus of this study is to investigate the influence of Organisational Health as non-financial indices on SMEs' growth in Nigeria. Research results revealed that SMEs in Nigeria suffer stagnation and high mortality rates despite financial factors. This suggests that these financial factors have not sufficiently impacted on SMEs' growth in Nigeria. This study is important because it is intended to fill the gap in previous research done by Jaja (2009) and Mezera and Spicka (2013) on financial indices by performing an in-depth analysis of the non-financial indices of selected Nigerian manufacturing firms. The conceptual framework of the study includes dimensions of Organisational Health classified as soft and hard factors. Soft factors are the behavioural aspects of management which are; perceived leadership and managerial capability. While the hard factors are work processes and control techniques; accountability and reporting structure. The non-financial elements of growth include success and survival. This interpretive phenomenological study adopted an inductive approach using the philosophical paradigm of constructivism to increase general understanding of situations. Consequently from the rich data gathered, ideas were induced but did not necessarily create new theories. This approach was used to inductively and holistically understand human experiences using case studies. Data collection methods included general observations and in-depth semi-structured interviews with a sample size of thirty respondents from ten manufacturing SMEs. Non-probability and stratified (strategic, tactical, operational) sampling techniques were used. The data analysis involved the use of Nvivo software. Key findings reveal that connectivity and relationship exist between dimensions of Organisational Health with capability and leadership on one hand and accountability and reporting structure on the other. All of which have influences on the survival and success of SMEs. It must be said however that capability and accountability have stronger influences on the growth of SMEs compared to leadership and reporting structure. This study revealed that the successes of SMEs are closely tied to socio-psychological processes and not merely to financing support. Contributing to knowledge, capability encompassing HR skills and accountability seem to be the ultimate foundation of Organisational Health. Entrepreneurs should be aware of industry conditions to improve their non-financing strategies and policy makers should understand the dimensions of Organisational Health in order to provide adequate training for them.

A Shell Theory for Chiral Single-Wall Carbon Nanotubes

description: In this paper, we propose a characterization of the mechanical response of the linearly elastic shell we associate to a single-wall carbon nanotube of arbitrary chirality. In Bajaj et al. 2013, we gave such a characterization in the case of zigzag and armchair nanotubes; in particular, we showed that the orthotropic response we postulated for the associated shells is to become isotropic in the graphene-limit, that is, when the shell radius grows bigger and bigger. Here we give an explicit recipe to construct the generally anisotropic response of the shell associated to a nanotube of any chirality in terms of the response of the shell associated to a related zigzag or armchair nanotube. The expected coupling of mechanical effects that anisotropy entrains is demonstrated in the case of a torsion problem, where the axial extension accompanying twist is determined analytically and found in good agreement with the available experimental data.

High energy emission from the nebula around the Black Widow binary system containing millisecond pulsar B1957+20

description: The features of pulsed $γ$-ray emission from classical and millisecond pulsars indicate that the high energy radiation processes in their inner magnetospheres occur in a similar way. In the last decade several TeV $γ$-ray nebulae have been discovered around classical pulsars. The above facts suggest that $γ$-rays should be produced also in the surroundings of millisecond pulsars. We discuss a model for the bow shock nebula around the well known Black Widow binary system containing the millisecond pulsar B1957+20. This model predicts the existence of a synchrotron X-ray and inverse Compton $γ$-ray nebula around this system. We want to find out whether $γ$-ray emission from the nebula around B1957+20 could be detected by the future and present Cherenkov telescopes. Using the Monte Carlo method we followed the propagation of relativistic electrons in the vicinity of the pulsar. We calculated the very high energy radiation produced by them in the synchrotron process and the inverse Compton scattering of the Microwave Background Radiation and of the infrared radiation from the galactic disk. We also computed the X-ray emission produced by the electrons in the synchrotron process. We show that the hard X-ray tail emission observed from the vicinity of B1957+20 can be explained by our model. Moreover, we predict that the TeV $γ$-ray emission produced by the electrons in the inverse Compton process should be detectable by the future Cherenkov Telescope Array and possibly by the long term observations with the present Cherenkov arrays such as MAGIC and VERITAS. The $γ$-ray emission from B1957+20 is expected to be extended, inhomogeneous, and shifted from the present location of the binary system by a distance comparable to the radius of the nebula.
