description: Microbial biofilms on stainless steel surfaces exposed to water from a freshwater pond were dominated by manganese-oxidizing bacteria, as initially diagnosed by microscopy and elemental analysis. The application of electron paramagnetic resonance (EPR) spectroscopy revealed conspicuous sextet (six-line) patterns that intensified with immersion time, implying the gradual accumulation of Mn(II) in the biofilms. Correspondingly, cathodic polarization designated the manganese oxide (MnOx) reduction peak in the form of a distinctive ‘nose’, which grew increasingly more negative with biofilm growth. The progressive expansion of cathodic current densities and the concurrent area-under-the-curve also allowed the quantification of microbially mediated MnOx deposition. Furthermore, the merger of EPR and cathodic polarization techniques yielded key insights, in tandem with Mn speciation data, into the pathways of microbial manganese transformations in biofilms, besides providing meaningful interpretations of prevailing literature. Accordingly, the natural freshwater biofilm was inferred as one supporting a complete manganese cycle encompassing multiple redox states.

description: We present the high-resolution X-ray spectrum of the low-redshift quasar H 1821+643 and its surrounding hot cluster observed with the Chandra High Energy Transmission Grating Spectrometer (HETGS). An iron emission line attributed to the quasar at ~6.43 keV (rest frame) is clearly resolved, with an equivalent width of ~100 eV. Although we cannot rule out contributions to the line from a putative torus, the diskline model provides an acceptable fit to this iron line. We also detect a weak emission feature at ~6.9 keV (rest frame). We suggest that both lines could originate in an accretion disk comprised of a highly ionized optically thin atmosphere sitting atop a mostly neutral disk. We search for absorption features from a warm/hot component of the intergalactic medium along the ~1.5Gpc/h line of sight to the quasar. No absorption features are detected at or above the 3 sigma level while a total of six OVI intervening absorption systems have been detected with HST and FUSE. Based on the lack of OVII and OVIII absorption lines and by assuming collisionally ionization, we constrain the gas temperature of a typical OVI absorber to 10^5 < T < 10^6 K, which is consistent with the results from hydrodynamic simulations of the intergalactic medium. The zeroth order image reveals the extended emission from the surrounding cluster. We have been able to separate the moderate CCD X-ray spectrum of the surrounding cluster from the central quasar and find that this is a hot cluster with a temperature of ~10 keV and a metal abundance of ~0.3 Zo. We also independently obtain the redshift of the cluster, which is consistent with the optical results. We estimate that the cluster makes negligible contributions to the 6.9 keV iron K line flux.

description: This payer presents a model framework and results that combine resource depletion with optimal economic growth and climate change in a macro-geoeconomic model. In doing so, the authors build upon the 'n Nordhaus DICE model to include the demands for coal, oil, and natural gas. These demands depend upon own price, prices of substitute fuels, per capita income, and population. The resource depletion model captures the effect on oil depletion of upward shifting demand curves which respond to population and income growth. A methodological advantage of including price, income, and population sensitive energy demand functions is that it allows substitution possibilities in the "production" of emissions. Furthermore, it allows the analysis of energy tax regimes in an environment of growing world population and income, non-decreasing energy and carbon intensity, and future, declining petroleum availability. •

These solutions are continuously self-similar near the central singularity. We analyze linear perturbations of these solutions, and discuss the subtle question of boundary conditions. We find two growing modes, one of which corresponds to the linearization of static singular solutions, while the other describes black hole formation.

description: Detection of forming planets means detection of the circumplanetary disk (CPD) in reality, since the planet is still surrounded by a disk at this evolutionary stage. Yet, no comprehensive CPD modeling was done in near-infrared wavelengths, where high contrast imaging is a powerful tool to detect these objects. We combined 3D radiative hydrodynamic simulations of various embedded planets with RADMC-3D radiative transfer post-processing that includes scattering of photons on dust particles. We made synthetic images for VLT NaCo/ERIS in the Ks, L', M' bands as well as examined the spectral energy distributions (SEDs) of disks between 1 $μm$ and 10 cm. We found that the observed magnitudes from the planet's vicinity will mostly depend on the CPD parameters, not on the planet's. The CPD is 20-100x brighter than the embedded planet in near-IR. We also show how the CPD parameters, e.g. the dust-to-gas ratio will affect the resulting CPD magnitudes. According to the SEDs, the best contrast ratio between the CPD and circumstellar disks is in sub-mm/radio wavelengths and between 8-33 microns in case if the planet opened a resolvable, deep gap ($\ge 5 \rm{M_{Jup}}$), while the contrast is particularly poor in the near-IR. Hence, to detect the forming planet and its CPD, the best chance today is targeting the sub-mm/radio wavelengths and the 10-micron silicate feature vicinity. In order to estimate the forming planet's mass from the observed brightness, it is necessary to run system specific disk modeling.

description: Home sharing has become a buzzword in recent decades. Although revenue is increasing year by year, the home-sharing industry still faces fierce competition, not only from the traditional hospitality industry but also from OTA (online travel agency) platforms and other house-sharing platforms. To survive in this competitive accommodation market, a growing number of organizations have begun to focus on improving customer experiences through cultivating customer engagement and loyalty, thereby obtaining and sustaining competitive advantage. On the other hand, AI techniques are also widely used in the sharing economy to enhance personalization, analyse data, and increase output. However, despite the importance of positive customer experience to home-sharing platforms, and the potential usage of AI as a service, there are specific gaps in the existing literature. Firstly, there is a lack of theoretical foundation to support the relationship between AI and customer experience. Secondly, the literature on how AI is utilized in the sharing economy remains to be consolidated. Finally, minimal studies exist which examine if and how AI can be adopted to enhance the customer experience in the home-sharing industry, improve customer loyalty, and gain competitive advantage. This thesis uses qualitative and quantitative research methods to address the research gaps. The first phase of this study includes content analysis and systematic quantitative literature review to identify the relationship between AI and the customer experience in service, and how AI is used in the sharing economy. The systematic quantitative literature review is significant in this period as it clarifies the research gap that leads to the empirical research in the second phase. The empirical investigation examines guests who have used home-sharing platforms regarding their experience with AI, as well as levels of trust, engagement and loyalty towards the platforms and hosts. Online surveys and structural equation models are used in the second phase. [...]

description: Being the polymorphs of calcium carbonate (CaCO3), vaterite and calcite have attracted a great deal of attention as promising biomaterials for drug delivery and tissue engineering applications. Furthermore, they are important biogenic minerals, enabling living organisms to reach specific functions. In nature, vaterite and calcite monocrystals typically form self-assembled polycrystal micro- and nanoparticles, also referred to as spherulites. Here, we demonstrate that alpine plants belonging to the Saxifraga genus can tailor light scattering channels and utilize multipole interference effect to improve light collection efficiency via producing CaCO3 polycrystal nanoparticles on the margins of their leaves. To provide a clear physical background behind this concept, we study optical properties of artificially synthesized vaterite nanospherulites and reveal the phenomenon of directional light scattering. Darkfield spectroscopy measurements are supported by a comprehensive numerical analysis, accounting for the complex microstructure of particles. We demonstrate the appearance of generalized Kerker condition, where several higher order multipoles interfere constructively in the forward direction, governing the interaction phenomenon. As a result, highly directive forward light scattering from vaterite nanospherulites is observed in the entire visible range. Furthermore, ex vivo studies of microstructure and optical properties of leaves for the alpine plants Saxifraga 'Southside Seedling' and Saxifraga Paniculata Ria are performed and underlined the importance of Kerker effect for these living organisms. Our results pave the way for a bioinspired strategy of efficient light collection by selfassembled polycrystal CaCO3 nanoparticles via tailoring light propagation directly to the photosynthetic tissue with minimal losses to undesired scattering channels.

description: We report the possible identification of weak methane spectral features in the near-infrared K band in two late L dwarfs, DENIS 0205-11 (L7) and 2MASS 1523+30 (L8). New, high signal-to-noise ratio flux-calibrated spectra, spanning the wavelength interval 1.10 - 2.35 microns with an average resolving power R = 1800 were obtained using NIRSPEC on the Keck II telescope. Results are reported and compared for three late L dwarfs (L5, L7, and L8) and two T dwarfs (T1 and T6). The spectra, which are continuous through the atmospheric absorption bands, show the development of deep steam bands and the weakening of iron hydride features through the L dwarfs and the emergence of strong methane bands in the T dwarfs. A detailed comparison of the K band regions with synthetic spectra suggests that the weak features seen in the L7 and L8 dwarfs at 2.20 microns are likely to be methane. We see no evidence for methane in the H band. At the R = 1800 resolution, significant differences are evident between the spectral signatures of the L8 and the T1, leaving room for additional transition objects (L9 or T0).

title: Assessment drives learning: how program-level assessment occurs in Australian universities
Creators: name: Charlton, Nicholas J
Publisher: name: Griffith University
Year: 2024
Subjects: subject: program-level assessment
subject: terminology
subject: higher education

description: The aim of this research was to explore if, and to what extent, program-level assessment is adopted in Australian universities, and if not, what are the barriers to it being adopted. Programmatic assessment (Schuwirth & Van der Vleuten, 2011; van der Vleuten et al., 2012) or program-focused assessment (Hartley & Whitfield, 2013; Whitfield & Hartley, 2019) are the terms used to describe the process of integrating assessment within a program of study. These two terms are used interchangeably and when taken in context, refer to a holistic approach to assessment throughout a program. Program-level assessment uses a backward mapping design process to arrange assessments strategically and holistically throughout a degree or program of study. Despite having construct validity, program-level assessment has not been widely adopted internationally (Whitfield & Hartley, 2017), except within medical education and health discipines (Hartley & Whitfield, 2013; Palermo et al., 2017; Roberts et al., 2022; Schut et al., 2021). This is in part due to the predominant modular approach to program and assessment design driven by national and international drivers that have resulted in the commodification and marketisation of higher education. This approach to program and assessment planning, results in a variable quality experience for the student, limits a deeper approach to study, encourages students to focus on their achievements in individual assessment tasks, rather than on the development of self-directed behaviours, such as critical and ethical thinking. The increase in accessibility and sophistication of generative artificial intelligence (Sullivan et al., 2023) provides an impetus to reform assessment practices to be more coordinated, valid and trustworthy (Tertiary Education Quality and Standards Agency, 2023). It should focus on career skill development not just context-specific learning. A program-level approach to assessment would achieve this and help students develop and apply skills and knowledge required for future careers. [...]

description: The lognormal distribution describing, e.g., exponentials of Gaussian random variables is one of the most common statistical distributions in physics. It can exhibit features of broad distributions that imply qualitative departure from the usual statistical scaling associated to narrow distributions. Approximate formulae are derived for the typical sums of lognormal random variables. The validity of these formulae is numerically checked and the physical consequences, e.g., for the current flowing through small tunnel junctions, are pointed out.

description: Larkin and Ovchinnikov established that the viscous flow of magnetic flux quanta in current-biased superconductor films placed in a perpendicular magnetic field can lose stability due to a decrease in the vortex viscosity coefficient $η$ with increasing velocity of the vortices $v$. The dependence of $η$ on $v$ leads to a $nonlinear$ section in the current-voltage ($I$-$V$) curve which ends at the flux-flow instability point with a voltage jump to a highly resistive state. At the same time, in contradistinction with the nonlinear conductivity regime, instability jumps often occur in $linear$ $I$-$V$ sections. Here, for the elucidation of such jumps we develop a theory of local instability of the magnetic flux flow occurring not in the entire film but in a narrow strip across the film width in which vortices move much faster than outside it. The predictions of the developed theory are in agreement with experiments on Nb films for which the heat removal coefficients and the inelastic scattering times of quasiparticles are deduced. The presented model of local instability is also relevant for the characterization of superconducting thin films whose performance is examined for fast single-photon detection.

description: In this study, we develop and estimate a censored LA/AIDS model using household-level purchase data. In addition to imposing non-negativitity constraints, we account for the endogeneity of unit value. We address the non-negativity issue using an Amemiya-Tobin approach, which imposes the adding-up condition on both observed and latent shares. We address the endogeneity of unit value by estimating share equations and unit value equations simultaneously. Given the need to evaluate high-order probability integrals, we use a simulated probability method in the model estimation. This model is applied to estimate and analyze a demand system featuring six fish and three meat commodities, using Norwegian household data.

description: We investigate the impact of gas evolution on the expected yields from deep Sunyaev-Zel'dovich (SZ) effect surveys as well as on the expected SZ effect contribution to fine scale anisotropy in the Cosmic Microwave Background. The approximate yields from SZ effect surveys are remarkably insensitive to gas evolution, even though the observable properties of the resulting clusters can be markedly different. The CMB angular power spectrum at high multipoles due to the SZ effect from clusters is quite sensitive to gas evolution. We show that moderate resolution SZ effect imaging of clusters found in deep SZ effect surveys should allow a good understanding of gas evolution in galaxy clusters, independent of the details of the nature of the gas evolution. Such an understanding will be necessary before precise cosmological constraints can be set from yields of large cluster surveys.

For each lattice size quenched averages are performed over 96 realizations. By using reweighting techniques and finite-size scaling analyses we investigate the critical properties of the model in the close vicinity of the phase transition point. Our random lattice data provide strong evidence that, for the available system sizes, the resulting effective critical exponents are indistinguishable from recent high-precision estimates obtained in Monte Carlo studies of the Ising model and ϕ^4 field theory on three-dimensional regular cubic lattices.

description: In a view of recent proposals for the realization of anisotropic light-matter interaction in such platforms as (i) non-stationary or inductively and capacitively coupled superconducting qubits, (ii) atoms in crossed fields and (iii) semiconductor heterostructures with spin-orbital interaction, the concept of generalized Dicke model, where coupling strengths of rotating wave and counter-rotating wave terms are unequal, has attracted great interest. For this model, we study photon fluctuations in the critical region of normal-to-superradiant phase transition when both the temperatures and numbers of two-level systems are finite. In this case, the superradiant quantum phase transition is changed to a fluctuational region in the phase diagram that reveals two types of critical behaviors. These are regimes of Dicke model (with discrete $\mathbb{Z}_2$ symmetry), and that of (anti-) and Tavis-Cummings $U(1)$ models. We show that squeezing parameters of photon condensate in these regimes show distinct temperature scalings. Besides, relative fluctuations of photon number take universal values. We also find a temperature scales below which one approaches zero-temperature quantum phase transition where quantum fluctuations dominate. Our effective theory is provided by a non-Goldstone functional for condensate mode and by Majorana representation of Pauli operators. We also discuss Bethe ansatz solution for integrable $U(1)$ limits.

description: We present VLA HI observations of JO206, a prototypical ram-pressure stripped galaxy in the GASP sample. This massive galaxy (M$_{\ast} =$ 8.5 $\times$ 10$^{10}$ M$_{\odot}$) is located at a redshift of $z =$ 0.0513, near the centre of the low-mass galaxy cluster, IIZw108 ($σ\sim575$ km/s). JO206 is characterised by a long tail ($\geq$90 kpc) of ionised gas stripped away by ram-pressure. We find a similarly long HI tail in the same direction as the ionised gas tail and measure a total HI mass of $3.2 \times 10^{9}$ M$_{\odot}$. This is about half the expected HI mass given the stellar mass and surface density of JO206. A total of $1.8 \times 10^{9}$ M$_{\odot}$ (60%) of the detected HI is in the gas stripped tail. An analysis of the star formation rate shows that the galaxy is forming more stars compared to galaxies with the same stellar and HI mass. On average we find a HI gas depletion time of $\sim$0.5 Gyr which is about four times shorter than that of "normal" spiral galaxies. We performed a spatially resolved analysis of the relation between star formation rate density and gas density in the disc and tail of the galaxy at the resolution of our HI data. The star formation efficiency of the disc is about 10 times higher than that of the tail at fixed HI surface densities. Both the inner and outer parts of JO206 show an enhanced star formation compared to regions of similar HI surface density in field galaxies. The enhanced star formation is due to ram-pressure stripping during the galaxy's first infall into the cluster.

description: Spherically symmetric, null dust clouds, like their time-like counterparts, may collapse classically into black holes or naked singularities depending on their initial conditions. We consider the Hamiltonian dynamics of the collapse of an arbitrary distribution of null dust, expressed in terms of the physical radius, $R$, the null coordinates, $V$ for a collapsing cloud or $U$ for an expanding cloud, the mass function, $m$, of the null matter, and their conjugate momenta. This description is obtained from the ADM description by a Kuchař-type canonical transformation. The constraints are linear in the canonical momenta and Dirac's constraint quantization program is implemented. Explicit solutions the constraints are obtained for both expanding and contracting null dust clouds with arbitrary mass functions.

description: A multi-wavelength analysis of the large Galactic infrared bubble N 24 is has been presented in this paper in order to investigate the molecular and star formation environment around expanding HII regions. Using archival data from Herschel and ATLASGAL, the distribution and physical properties of the dust over the entire bubble are studied. Twenty three dense clumps are identified using the Clumpfind2d algorithm with sizes and masses in the range 0.65-1.73 pc and 600-16300 Msun, respectively. To analyse the molecular environment in N 24, observations of NH3 (1,1) and (2,2) were carried out using the Nanshan 26m radio telescope. Analysis of the kinetic temperature and gravitational stability of these clumps suggests gravitational collapse in several of them. The mass-size distributions of the clumps and the presence of massive young protostars indicate that the shell of N 24 is a region of ongoing massive star formation. The compatibility of the dynamical and fragmentation time-scales and the overabundance of YSOs and clumps on the rim suggest that the collect and collapse mechanism is in play at the boundary of the bubble, but the existence of the IRDC at the edge of bubble indicates that radiation-driven implosion mechanism may also have played a role there.

description: Dairy cow ownership has been widely promoted by a number of development projects in Kenya (and other countries in East Africa) for the last two decades, and the country has the largest population of smallholder producers with dairy cows in sub-Saharan Africa. Supporters of dairy development efforts often have assumed that there will be positive nutritional impacts from increased milk consumption by dairy cow-owning households. This expectation has been further strengthened by recent research findings about the micronutrient benefits of animal product consumption. However, the nutritional impacts of more intensive dairying have received relatively little study to date in East Africa. This paper develops a conceptual framework that identifies key pathways through which dairy cow ownership may have both positive and negative impacts on child nutritional status. Using household- and child-level data on dairy cow owners and non-owners in coastal and highland Kenya, two alternative econometric models are used to estimate the impacts of the number of dairy cows owned, controlling for child characteristics, household head characteristics, and other household characteristics. To explore a principal hypothesized pathway through which dairy cows may influence nutritional outcomes, additional econometric models explore the impact of household income on nutritional status. Consistent with two previous studies, cattle ownership per se had a statistically significant positive impact on height-for-age (a measure of longer-term growth) in both regions. The number of dairy cows has a limited impact on weight-for-height, a measure of short-term child nutritional status. In coastal Kenya, however, there is evidence that dairy cow ownership has a positive impact on height-for-age. Household income has limited positive impacts on nutritional status at the coast. In the Kenyan highlands, our results suggest a marginally significant negative impact of household income on both weight-for-height, but existing data do not allow exploration of the sources of this anomalous result. Overall, the evidence suggests that dairy cow ownership per se does not result in negative nutritional impacts of dairy cow ownership, which implies that dairy development efforts have not increased child malnutrition. However, the evidence also suggests that positive nutritional ii impacts expected for more intensive dairying—particularly from increases in household income—may be limited. Further site-specific study of the pathways influencing household nutrient allocation, child morbidity, and labor requirements should be undertaken to inform policy and program efforts to enhance the nutritional benefits of dairy cow ownership.

description: We show that induction over $Δ(\mathbb R)$-definable well-founded classes is equivalent to the reflection principle which asserts that any true formula of first order set theory with real parameters holds in some transitive set. The equivalence is proved in primitive recursive set theory (which is weaker than Kripke-Platek set theory) extended by the axiom of dependent choice.

description: Belt and Road Initiative is an ambitious plan of China that can significantly change the global trade. It aims to connect and co-operate China across six main economic corridors. 29 economies are involved in BRI project from Europe and Central Asia and one of them is Georgia. Georgia gets involved in Silk Road project with its new port in Anaklia city, which is under construction and Baku-Tbilisi-Kars railway. China’s economic plan is not new thing for Georgia, because it has already been included in the same Silk Road project centuries ago. In the past few years, economic cooperation between Georgia and China deepened. On 1January 2018, free-trade agreement between Georgia and China came into force and Georgia became the first country in Eurasia to conclude a free-trade agreement with China. After Russia, China became the second-biggest wine market for Georgia.Scientific work ‘China’s Belt and Road Initiative and Georgia as a Participating Economy’ describes the importance of BRI for participating countries, particularly for Georgia and China. It includes five parts: introduction, observation, findings, conclusion and bibliography. The major research, findings, with qualitative and quantitative methods, responds to the question, what will be benefits for Georgia and China after the full implementation of BRI? – For Georgia, close relations with China means increased trade flow. Georgian-Chinese relations also complement the country’s Euro-Atlantic orientation and its ongoing integration. The BRI gives more importance to Anaklia Deep Sea Port, which will expand the efficiency of Georgian economy. Anaklia port can solve the unemployment problem in western Georgia. Ecologically, BRI sustainable development motivation is vital for Georgia, because Tbilisi faces problems in green transportation, green building and green energy. Large infrastructure projects of BRI can mitigate current overcapacity in Chinese steel and construction sectors. The initiative will be an economic stimulus package for its Western and Central Provinces, which witness rapidly growing income inequality. The BRI will support China’s need to promote itself in high technology and service sectors.
Supermassive Black Holes in Nuclei of Galaxies

description: We review the motivation and search for supermassive black holes (BHs) in galaxies. Energetic nuclear activity provides indirect but compelling evidence for BH engines. Ground-based dynamical searches for central dark objects are reviewed in Kormendy & Richstone (1995, ARA&A, 33, 581). Here we provide an update of results from the HST. As of 2001 March, dynamical BH detections are available for at least 37 galaxies. The demographics of these objects lead to the following conclusions: (1) BH mass correlates with the luminosity of the bulge component of the host galaxy. The median BH mass fraction is 0.13% of the mass of the bulge. (2) BH mass correlates with the mean velocity dispersion of the bulge inside its effective radius. For the best mass determinations, the scatter is consistent with the measurement errors. (3) BH mass correlates with the luminosity of the high-density central component in disk galaxies independent of whether this is a real bulge (a mini-elliptical, believed to form via a merger-induced dissipative collapse and starburst) or a ``pseudobulge'' (believed to form by inward transport of disk material). (4) BH mass does not correlate with the luminosity of galaxy disks. If pure disks contain BHs, then their masses are much smaller than 0.13% of the mass of the disk. We conclude that present observations show no dependence of BH mass on the details of whether BH feeding happens rapidly during a collapse or slowly via secular evolution of the disk. The above results increasingly support the hypothesis that the major events that form a bulge or elliptical galaxy and the main growth phases of its BH -- when it shone like a quasar -- were the same events.

description: Computational Grids, emerging as an infrastructure for next generation computing, enable the sharing, selection, and aggregation of geographically distributed resources for solving large-scale problems in science, engineering, and commerce. As the resources in the Grid are heterogeneous and geographically distributed with varying availability and a variety of usage and cost policies for diverse users at different times and, priorities as well as goals that vary with time. The management of resources and application scheduling in such a large and distributed environment is a complex task. This thesis proposes a distributed computational economy as an effective metaphor for the management of resources and application scheduling. It proposes an architectural framework that supports resource trading and quality of services based scheduling. It enables the regulation of supply and demand for resources and provides an incentive for resource owners for participating in the Grid and motives the users to trade-off between the deadline, budget, and the required level of quality of service. The thesis demonstrates the capability of economic-based systems for peer-to-peer distributed computing by developing users' quality-of-service requirements driven scheduling strategies and algorithms. It demonstrates their effectiveness by performing scheduling experiments on the World-Wide Grid for solving parameter sweep applications.

description: Most European farmers receive direct payments under the Single Payment Scheme and in addition, are member of farm certification schemes. Incentives to participate in these schemes are manifold: farm requirements often at least partially overlap, farm structure allows rather easy compliance, but also low monitoring intensities, detection rates, or sanctions may contribute to “free ride” on participation. The paper develops a theoretical model that explains farmer’s joint compliance behaviour and determinants of participation and tests the model using individual farm survey data. Evidence from the survey indicates that farmers weigh the relevance of compliance, control, detection and sanctions differently for the Single Payment Scheme and farm certification but strive to comply with all rules. Hence, potentially expected trade-off between costs and gains of participation and related compliance behaviour only partially occurs.

description: As a continuation of the study of the herding model proposed in (Bae et al. in arXiv:1712.01085, 2017), we consider in this paper the derivation of the kinetic version of the herding model, the existence of the measure-valued solution and the corresponding herding behavior at the kinetic level. We first consider the mean-field limit of the particle herding model and derive the existence of the measure-valued solutions for the kinetic herding model. We then study the herding phenomena of the solutions in two different ways by introducing two different types of herding energy functionals. First, we derive a herding phenomena of the measure-valued solutions under virtually no restrictions on the parameter sets using the Barbalat's lemma. We, however, don't get any herding rate in this case. On the other hand, we also establish a Grönwall type estimate for another herding functional, leading to the exponential herding rate, under comparatively strict conditions. These results are then extended to smooth solutions.
