description: There are two modes by which clusters of aggregating particles can coalesce: The clusters can merge either (i) by the Ostwald ripening process in which particles diffuse from one cluster to the other whilst the cluster centres remain stationary, or (ii) by means of a cluster translation mode, in which the clusters move towards each other and join. To understand in detail the interplay between these different modes, we study a model system of hard particles with an additional attraction between them. The particles diffuse along narrow channels with smooth or periodically corrugated walls, so that the system may be treated as one-dimensional. When the attraction between the particles is strong enough, they aggregate to form clusters. The channel potential influences whether clusters can move easily or not through the system and can prevent cluster motion. We use Dynamical Density Functional theory to study the dynamics of the aggregation process, focusing in particular on the coalescence of two equal size clusters. As long as the particle hard-core diameter is non-zero, we find that the coalescence process can be halted by a sufficiently strong corrugation potential. The period of the potential determines the size of the final stable clusters. For the case of smooth channel walls, we demonstrate that there is a cross-over in the dominance of the two different coarsening modes, that depends on the strength of the attraction between particles, the cluster sizes and the separation distance between clusters.

description: The relation between the progenitor mass and the kinetic energy of the explosion is a key toward revealing the explosion mechanism of stripped-envelope (SE) core-collapse (CC) supernovae (SNe). Here, we present a method to derive this relation using the nebular spectra of SESNe, based on the correlation between the [O~I]/[Ca~II], which is an indicator of the progenitor mass, and the width of [O~I], which measures the expansion velocity of the oxygen-rich material. To explain the correlation, the kinetic energy ($E_{\rm K}$) is required to be positively correlated with the progenitor mass as represented by the CO core mass ($M_{\rm CO}$). We demonstrate that SNe IIb/Ib and SNe Ic/Ic-BL follow the same $M_{\rm CO}$-$E_{\rm K}$ scaling relation, which suggests the helium-rich and helium-deficient SNe share the same explosion mechanism. The $M_{\rm CO}$-$E_{\rm K}$ relation derived in this work is compared with the ones from early phase observations. The results are largely in good agreement. Combined with early phase observation, the method presented in this work provides a chance to scan through the ejecta from the outermost region to the dense inner core, which is important to reveal the global properties of the ejecta and constrain the explosion mechanism of core-collapse supernovae.

description: Taking a pragmatic approach to the processes involved in the phenomena of collective opinion formation, we investigate two specific modifications to the co-evolving network voter model of opinion formation, studied by Holme and Newman [1]. First, we replace the rewiring probability parameter by a distribution of probability of accepting or rejecting opinions between individuals, accounting for the asymmetric influences in relationships among individuals in a social group. Second, we modify the rewiring step by a path-length-based preference for rewiring that reinforces local clustering. We have investigated the influences of these modifications on the outcomes of the simulations of this model. We found that varying the shape of the distribution of probability of accepting or rejecting opinions can lead to the emergence of two qualitatively distinct final states, one having several isolated connected components each in internal consensus leading to the existence of diverse set of opinions and the other having one single dominant connected component with each node within it having the same opinion. Furthermore, and more importantly, we found that the initial clustering in network can also induce similar transitions. Our investigation also brings forward that these transitions are governed by a weak and complex dependence on system size. We found that the networks in the final states of the model have rich structural properties including the small world property for some parameter regimes. [1] P. Holme and M. Newman, Phys. Rev.

description: This research work focused on investigating factors impeding and promoting E-government development in Lagos State of Nigeria through the lens of the government’s e-Service initiates. Empirical evidence in this work suggest that E-government maturity in governmental Ministries in Lagos State are at mixed stages of development, ranging from ‘emerging’ to ‘transactional’ with reference to the United Nation’s E-government benchmarks on frameworks used in assessing developmental stages of E-government. Major factors found to impede E-government development in Lagos State Government Ministries are issues of inadequate E-government infrastructure and E-readiness issues, lack of technically skilled workforce, issues related to funding, inadequate political will to develop and support electronic forms of government initiatives, and resistance to organisational transformation and change. Major factors found to facilitate electronic government development in Lagos State Government Ministries are issues related to reduction in corrupt practises in public-sector organisations, encouragement of accountability and transparency in public-sector organisations, and reduction in overall cost of running public-sector organisations. The findings highlighted above can generalise across other regions in Nigeria and are consistent with literature on E-government development and implementation in emerging economies around the world. The research work was conducted according to the mixed-method research tradition. Using an exploratory sequential research design that uses both the qualitative and quantitative strands of enquiry, the researcher was able to investigate various factors impacting E-government development in Lagos State which can generalise to other regions across Nigeria. The E-government research framework is underpinned by relevant E-government theories, frameworks, maturity models and interrelated concepts of Network and cross-agency collaboration processes. Research participants used in this work are drawn mainly from selected Ministries of the Lagos State government in Nigeria. The techniques for collecting the research data included document reviews, research visits and interviews, and the use of survey questionnaire. Finally, the study revealed that Lagos State Government Ministries exist in silos, with non-existent cross-agency collaboration and Networking among governmental organisations.

description: Mapping our universe in 3D by imaging the redshifted 21 cm line from neutral hydrogen has the potential to overtake the cosmic microwave background as our most powerful cosmological probe, because it can map a much larger volume of our Universe, shedding new light on the epoch of reionization, inflation, dark matter, dark energy, and neutrino masses. We report on MITEoR, a pathfinder low-frequency radio interferometer whose goal is to test technologies that greatly reduce the cost of such 3D mapping for a given sensitivity. MITEoR accomplishes this by using massive baseline redundancy both to enable automated precision calibration and to cut the correlator cost scaling from N^2 to NlogN, where N is the number of antennas. The success of MITEoR with its 64 dual-polarization elements bodes well for the more ambitious HERA project, which would incorporate many identical or similar technologies using an order of magnitude more antennas, each with dramatically larger collecting area.

description: We investigate inflationary models in f(R,T) modified gravity with a kinetic coupling term ω^2 G^{μν}\partial_μϕ\partial_νϕhaving a positive factor needed to remove the ghosts. Taking f(R,T)=R+2βT, we calculate and analyse the relevant observable quantities including the spectral index $n_s$ and the tensor-to-scalar ratio r using the slow-roll approximations. Concretely, we consider two scenarios described by the decoupling and the coupling behaviors between the scalar potential and the f(R,T) gravity via the moduli space by dealing with two potentials being the quartic one V(ϕ) =λϕ^4 and the small field inflation V(ϕ) =V_0(1- (\fracϕμ)^α). For the quartic inflation model, we consider a decoupling behavior. For the small field inflation, however, we present the parameter decoupling and coupling scenarios. For both scenarios, we compute and inspect n_s and r showing interesting results. For three different values of the number of e-folds N=60,65 and 70, we find that the coupling between f(R,T)1 and the scalar potential via the moduli space provides an excellent agreement with the observational findings. In the last part of this work, we provide a possible discussion on the amplitude of scalar power spectrum needed to provide a viability of the proposed theory. Considering the second potential form in the parameter coupling scenario, we find acceptable values in certain points of the moduli space.

description: Heleomyzidae
Though the identity of this family, proposed by Westwood in 1840, is quite uncertain (McAlpine 2007) it contains, nonetheless, more than 750 species (Evenhuis & Pape 2020) predominantly from temperate northern regions but also some from the Neotropical and Australasian regions. In his “ Stirps Scatophaginae ”, rather than in the family Heleomyzidae, Rondani (1866d) described nine Palaearctic nominal species. Two are currently considered as valid, six as junior synonyms and one as doubtful (Gorodkov 1984b, Canzoneri et al. 1995). In his paper on the Rondani types at MZUB, Morge (1959b) listed one unpublished name (nomen nudum) of Rondani. Papp (1980) designated a lectotype for Helomyza tuberiperda Rondani, 1866 in the MZUF. The type material has been recovered for all nominal species and is in the MZUF; additional syntypes of one species are in the MZLU.

Subjects: Business information management (incl. records, knowledge and intelligence)

description: This present thesis is based on the critical conceptualisation of the leadership and the organisational change. Leadership is an action of the leading group of the people and company. It is a practical skill and research area that encompassing the ability of a person or company to lead other people in, team and firm. The organisational change is about the procedure of changing processes, culture, strategies and technologies of the company. It is a process under which a company make changes in its working methods and aim effectively, investigating the leadership style of the top management executives, including the Chief Executive Officer of Royal Jordanian airline to understand the factors that influence organisational cultural change within the company. There have been few studies of the Middle-Eastern situation that treats organisational cultural change in the development of an organisation in terms of the values of the company. What leadership is and what leaders do within the context of organisations based in the Middle-Eastern region deserve deeper investigation and analysis. The researcher has developed a conceptual framework and a set of propositions to analyse the relationship between leadership, organisational change and effective organisational performance. The aim is to convey the aspiration of developing a theoretical contribution to knowledge about leadership and organisational change as mediated by Arab cultural traits by investigating the case of leadership in the Royal Jordanian airline.

description: The dependence of the lower critical solution temperature (LCST) of charged, thermosensitive copolymers on their charge fraction and the salt concentration is investigated by employing systematic cloud-point experiments and analytical theory. The latter is based on the concept of the Donnan equilibrium incorporated into a thermodynamic expansion of a two-state free energy around a charge-neutral reference homopolymer and should be applicable for weakly charged (or highly salted) polymer systems. Very good agreement is found between the theoretical description and the experiments for aqueous solutions of the responsive copolymer poly(NIPAM-co-EVImBr) for a wide range of salt concentrations and charge fractions up to 8%, using only two global, physical fitting parameters.

description: Calliphoridae
This worldwide family contains more than 1,300 species (Evenhuis & Pape 2020), the fewest in the Neotropics where less than 100 species are known (James 1970). Rondani (1848b, 1850 c, 1851, 1862d, 1863, 1865 c, 1868a, 1873e, 1875c) described five Palaearctic, ten Neotropical, five Oriental and one Afrotropical nominal species in his “ Stirps Muscinae ”. The family Calliphoridae was proposed by Brauer & Bergenstamm (1889). Six of these are currently considered as valid, six as junior synonyms and nine as doubtful or had not been included in any recent catalog (James 1970, 1977, Pont 1980b, Dear 1985, Schumann 1986, Rognes 1991a, 1991b, Pape et al. 1995, Mac- Lean & González 2006, Kurahashi 2007, Kosmann et al. 2013, Wolff & Kosmann 2016, Velásquez et al. 2017, Evenhuis & Pape 2020). Rondani proposed one new replacement name for species previously described and named by Macquart. Except for two species, which have presumably been lost, the type material has been recovered for all nominal species and is distributed among the MZUF (six), MSNG (six), MZUN (four), MSNC (two), MRSN (two), MSNPV (one), and NHMW (one).

description: The following study is aimed at examination and analysis of the influence of hedonic and materialistic values on compulsive buying behaviour among Pakistani shoppers. The study has followed a mixed design for research combining both qualitative and quantitative methods. The data has been collected through primary and secondary means but the core focus has been primary data for purpose of analysis and presentation of results. Furthermore, the study is a causal study which is cross-sectional conducted through survey questionnaire and interviews as part of mixed design. 200 subjects have been selected for questionnaire while 100 interviews have been conducted from shoppers in Pakistanthrough simple random and stratified sampling respectively. Data is analysed through SPSS using reliability, frequency, correlation and regression analysis while qualitative data is analysed through thematic analysis. The results revealed that influence of hedonic and materialistic values on compulsive buying behaviour is significant. Further quantitative and qualitative analysis revealed that hedonic and materialistic values are major influencers for compulsive buying behaviour because people that tend to adopt these behaviour are either triggered by hedonic values that are related to internal satisfaction, culture or pleasure seeking or either by materialistic values such as possession of wealth, possessions of materialistic and valuable items, societal image or societal status.

In 2017 Moshchevitin studied the corresponding Diophantine constant $\mathfrak{k}(α) = \liminf\limits_{t\to\infty} t \cdotψ_α^{[2]}(t)$ and the corresponding spectrum $\mathbb{L}_2 = \{ λ~| ~\existsα\in\mathbb{R\setminus Q} \colon λ= \mathfrak{k}(α) \}$. In particular, he calculated two largest elements of the spectrum $\mathbb{L}_2$. In the present paper we calculate the value for the third element of the spectrum $\mathbb{L}_2$.

description: Dynamic mode decomposition (DMD) is a powerful and increasingly popular tool for performing spectral analysis of fluid flows. However, it requires data that satisfy the Nyquist-Shannon sampling criterion. In many fluid flow experiments, such data are impossible to capture. We propose a new approach that combines ideas from DMD and compressed sensing. Given a vector-valued signal, we take measurements randomly in time (at a sub-Nyquist rate) and project the data onto a low-dimensional subspace. We then use compressed sensing to identify the dominant frequencies in the signal and their corresponding modes. We demonstrate this method using two examples, analyzing both an artificially constructed test dataset and particle image velocimetry data collected from the flow past a cylinder. In each case, our method correctly identifies the characteristic frequencies and oscillatory modes dominating the signal, proving the proposed method to be a capable tool for spectral analysis using sub-Nyquist-rate sampling.

description: We present a three-dimensional, time-dependent, MHD simulation of the short-term interaction between a protoplanetary disk and the stellar corona in a T Tauri system. The simulation includes the stellar magnetic field, self-consistent coronal heating and stellar wind acceleration, and a disk rotating at sub-Keplerian velocity to induce accretion. We find that initially, as the system relaxes from the assumed initial conditions, the inner part of the disk winds around and moves inward and close to the star as expected. However, the self-consistent coronal heating and stellar wind acceleration build up the original state after some time, significantly pushing the disk out beyond $10R_\star$. After this initial relaxation period, we do not find clear evidence of a strong, steady accretion flow funneled along coronal field lines, but only weak, sporadic accretion. We produce synthetic coronal X-ray line emission light curves which show flare-like increases that are not correlated with accretion events nor with heating events. These variations in the line emission flux are the result of compression and expansion due to disk-corona pressure variations. Vertical disk evaporation evolves above and below the disk. However, the disk - stellar wind boundary stays quite stable, and any disk material that reaches the stellar wind region is advected out by the stellar wind.

description: We present a detailed study on the charge ordering (CO) transition in GdBaCo2O5 system by combining high resolution synchrotron powder/single crystal diffraction with electron paramagnetic resonance (EPR) experiments as a function of temperature. We found a second order structural phase transition at TCO=247 K (Pmmm to Pmma) associated with the onset of long range CO. At Tmin = 1.2TCO, the EPR linewidth rapidly broadens providing evidence of spin fluctuations due to magnetic interactions between Gd3+ ions and antiferromagnetic couplings of Co2+/Co3+ sublattices. This likely indicates that, analogously to manganites, the long-range antiferromagnetic order in GdBaCo2O5 sets in at TCO. Pair distribution function (PDF) analysis of diffraction data revealed signatures of structural inhomogeneities at low temperature. By comparing the average and local bond valences, we found that above TCO the local structure is consistent with a fully random occupation of Co2+ and Co3+ in a 1:1 ratio and with a complete charge ordering below TCO. Below T = 100 K the charge localization is partially melted at the local scale, suggesting a reentrant behavior of CO. This result is supported by the weakening of superstructure reflections and the temperature evolution of EPR linewidth that is consistent with paramagnetic (PM) reentrant behavior reported in the GdBaCo2O5.5 parent compound.

description: Existing literature exposes poor eating habits and low vegetable consumption as rife amongst adolescents. Increased autonomy in relation to decision-making around food often follows the onset of secondary school education. Studies have shown that adolescents are vulnerable to peer pressure because they want to fit in with their peers. The aim of this research was to develop a detailed insight into young adolescents’ (aged 11- to 13-years-old) behaviour concerning vegetables through exploratory research. The findings will inform the vegetable marketing of the company partner, Puffin Produce (who currently package Welsh fresh produce for supermarkets across Wales). A triangulated research methodology incorporated quantitative and qualitative data collection predominantly from schools in South Wales. Phase One involved collecting data from school canteen purchases (n=3 secondary schools), qualitative school catering manager interviews (n=6), catering staff focus groups (n=14) and parent focus groups (n=5). Phase Two included school canteen observations (n=3 secondary schools) and adolescent focus groups (n=42). A design period preceded the participatory design research with adolescents (n=41) and final parent focus groups (n=16) (Phase Three). Abductive thematic analysis resulted in numerous themes, the three most pertinent being convenience, taste preferences and parenting. This study fills three identified ‘gaps’ in the literature: the novel use of catering staff participants, the geographical research area of South Wales and the incorporation of adolescents in the participatory design research. The original contributions to knowledge includes an understanding into the factors influencing Welsh adolescents’ (aged 11- to 13-years-old) attitudes towards vegetables in addition to their food consumption routines and behaviours. Moreover, these insights are of commercial interest and could potentially inform the marketing communications of food companies seeking to target this market and improve healthful eating. The NPD process resulted in a vegetable-based snacking concept that is innovative yet feasible, suitable for Puffin Produce to develop further.
A note on M2-branes in opposite charge

description: The flux singularity that arise when branes are put in an oppositely charged background is a wildly discussed issue and in this paper the problem is investigated further. New AdS world volume (anti-)M2-brane solutions are constructed by placing the brane in a background where the charge dissolved in the flux is opposite that of the brane. A topological obstruction is derived to show how the singularity develops during localisation of this solution and any similarly constructed solution. Furthermore the singularity is shown not to be possible to hide behind a horizon, which would have given credence to a possible M-theory resolution.

description: Miltogramma punctatella Rondani, 1868
ORIGINAL DESCRIPTION: 1868a: 40.
TYPE LOCALITY: “ in colle agri parmensis [Parmese hill (Italy)]”.
TYPE MATERIAL: 1 ♀, lectotype (missing mid- and hind-legs, abdomen glued to a cardboard stage pinned below specimen) (MZUF: Box 14): Miltogramma Mgn / punctatella Rnd. / 718 / holotype ♀ Miltogramma punctatella Rnd., ♀, T. Pape det., 1986 / Senotainia albifrons (Rnd.), T. Pape det., 1986.
PARALECTOTYPES NOT EXAMINED: 1 ♂ (MSNC: Box DIPTERA Ex collezione Rondani - I): Sphixapata albifrons Rnd. 94 ♂ ♀ Parma / Coll. Rondani, scatola n° 1, posiz. H-11 / Museo di Storia Naturale Università di Pisa, Calci (PI) ex collezione Rondani; 1 ♀ (MSNC: Box DIPTERA Ex collezione Rondani - I): Sphixapata albifrons Rnd. ♀ Parm. / Coll. Rondani, scatola n° 1, posiz. H-12 / Museo di Storia Naturale Università di Pisa, Calci (PI) ex collezione Rondani.
CURRENT STATUS: junior synonym of Miltogramma punctatum Meigen, 1824 (Verves 1986: 75); junior synonym of Senotainia albifrons (Rondani, 1859) (Pape 1988: 14, 1996: 134).
REMARKS: Rondani (1868a: 40) described Miltogramma punctatella from just the female sex, without specifying either the number or the length of the specimens: “(Foem.) … semel capta [(Fem.[ale]) … collected once]”. Pape (1988: 14) reported a ‘holotype’ in the MZUF without knowing of two additional syntypes (one male and one female) in the MSNC, which brings the original syntype series to three specimens. In his original description, Rondani did not explicitly refer to a single female specimen, therefore Pape’s reference to a ‘holotype’ specimen must be considered as a lectotype (I.C.Z.N. 1999: Article 74.6). The additional syntypes in the MSNC not examined by Pape are paralectotypes.

description: The Bombax ceiba L. tree is a member of the family Bombacaceae and the genus Bombax. Both Chinese and Indian traditional medicine have made extensive use of it in the treatment of sickness. Its chemical composition is still a mystery. B. ceiba roots methanol extract (BCRME) was analyzed by different chromatographic analytical techniques in order to identify its major chemical constituents. Twelve compounds and six compounds were identified from GC–MS and LC–MS analysis, respectively. This is the first report on the presence of lathodoratin, cedrene, 4H-1-benzopyran-4-one,8-[{dimethylamino} methyl]-7-methoxy-3-methyl-2-phenyl, asiatic acid, and (E)-2,4,4'-trihydroxylchalcone in B. ceiba roots. Methanol extract demonstrated noteworthy antibacterial activity against Staphylococcus aureus (MTCC96) (MIC: 100 µg/mL) compare to antibiotic ampicillin (MIC: 250 µg/mL) as well as the highest α-amylase inhibition (IC50=26.91 µg/mL) and α-glucosidase inhibition (IC50=21.21 µg/mL) effects, molecular docking study confirmed these findings, with some compounds having a very high docking score.

description: We propose to probe the Higgs boson decay to invisible particles at a muon collider by observing the forward muons that are produced in association with the Higgs in the Z-boson fusion channel. An excellent sensitivity is possible in line of principle, owing to the large number of produced Higgs bosons, provided a forward muon detector is installed. We find that the resolution on the measurement of the muon energy and angle will be the main factor limiting the actual sensitivity. This poses tight requirements on the forward muon detector design.

description: The possible time variation of the fundamental constants of nature has been an active subject of research in modern physics. In this paper, we propose a new method to investigate such possible time variation of the speed of light $c$ using the updated Hubble diagram of high-redshift standard candles including Type Ia Supernovae (SNe Ia) and high-redshift quasars (based on UV-X relation). Our findings show that the SNe Ia Pantheon sample, combined with currently available sample of cosmic chronometers, would produce robust constraints on the speed of light at the level of $c/c_0=1.03\pm0.03$. For the Hubble diagram of UV+X ray quasars acting as a new type of standard candles, we obtain $c/c_0=1.19\pm0.07$. Therefore, our results confirm that there is no strong evidence for the deviation from the constant speed of light up to $z\sim 2$. Moreover, we discuss how our technique might be improved at much higher redshifts ($z\sim5$), focusing on future measurements of the acceleration parameter $X(z)$ with gravitational waves (GWs) from binary neutron star mergers. In particular, in the framework of the second-generation space-based GW detector, DECi-hertz Interferometer Gravitational-wave Observatory (DECIGO), the speed of light is expected to be constrained with the precision of $Δ{c}/c=10^{-3}$.

description: Ausgangspunkt des vorliegenden Beitrags bilden die Fragmentierung des studentischen Wissens und die Schwierigkeit, das Wissen in praktischen Situationen anzuwenden. Eine Möglichkeit, mit diesen Herausforderungen der Professionalisierung in der universitären Lehrer*innenbildung umzugehen, liegt in der Entwicklung von Lehretandems zwischen Fachdidaktik und Bildungswissenschaften, in denen Lerngelegenheiten zur Vernetzung und Anwendung des Wissens geschaffen werden. Im vorliegenden Beitrag werden die Überlegungen, theoretischen Grundlagen und didaktischen Entscheidungen von Dozentinnen aus der Musikdidaktik und den Bildungswissenschaften präsentiert, die ein solches Lehretandem für die Vorbereitung des Praxissemesters im Lehramtsstudium geplant und erprobt haben.
