To graze or not to graze livestock in public forests

Year: 2024

description: Forest ecosystems are important for the social, economic, and environmental well-being of many people globally. However, with the growing human needs and the impacts of climate change, there is an emerging forest policy discourse on whether to allow or disallow livestock grazing in public forests. This study used a case study research design and document content analysis to share comparative insights on the effects of forest grazing in two critical forest ecosystems in Kenya. The key documents reviewed included official government publications, policy papers, strategic plans, academic articles, relevant case studies from government websites, academic databases, international organizations, and research institutions specializing in sustainable forest management. The findings indicate that Kenya is endowed with diverse forest capital with immense potential for contributing to sustainable development. However, there is a complex interplay between livestock grazing and forest ecosystems. Insights from Mau and Aberdares indicate that livestock grazing in the two ecosystems under the current grazing system has a positive socio-economic impact. However, due to overgrazing by livestock, there are significant negative environmental impacts such as soil degradation, compaction, and erosion, reducing the forest land's ability to retain water and support plant growth, reduction in biodiversity, exacerbating the spread of invasive species, and increased vulnerability to natural disasters such as floods and landslides besides increased carbon emissions. Moreover, despite deploying several strategies to enhance sustainability, there is no adequate monitoring framework for the indicators of grazing impacts. Based on the precautionary principle, this study recommends banning livestock grazing in the two ecosystems. However, a "win-win" arrangement should be developed to enhance the "cut and carry system" for fodder from the two forests to promote livelihoods and socio-economic empowerment. These findings are critical for promoting the sustainable management of critical water towers with similar contexts in the country and enhancing the achievement of various national development aspirations, such as the aspiration to plant 15 billion trees by 2032 and a host of climate-related commitments.

title: Fermionic excitations at finite temperature and density

description: We study fermionic excitations in a hot and dense strongly interacting medium consisting of quarks and (pseudo-)scalar mesons. In particular, we use the two-flavor quark-meson model in combination with the functional renormalization group (FRG) approach, which allows to take into account the effects from thermal and quantum fluctuations. The resulting fermionic excitation spectrum is investigated by calculating the quark spectral function at finite temperature, quark chemical potential, and spatial momentum. This involves an analytic continuation from imaginary to real energies by extending the previously introduced analytically continued FRG method to the present case. We identify three different collective excitations in the medium: the ordinary thermal quark, the plasmino mode, and an ultrasoft “phonino” mode. The dispersion relations of these modes are extracted from the quark spectral function. When compared to corresponding results from an FRG-improved one-loop calculation, a remarkable agreement has been found.
The inviscid limit and stability of characteristic boundary layers for the compressible Navier-Stokes equations with Navier-friction boundary conditions
Creators: name: Williams, Mark
name: Wang, Ya-Guang

Year: 2012

description: We study boundary layer solutions of the isentropic, compressible Navier-Stokes equations with Navier-friction boundary conditions when the viscosity constants appearing in the momentum equation are proportional to a small parameter ϵ. These boundary conditions are characteristic for the underlying inviscid problem, the compressible Euler equations. The boundary condition implies that the velocity on the boundary is proportional to the tangential component of the stress. The normal component of velocity is zero on the boundary. We first construct a high-order approximate solution that exhibits a boundary layer. The main contribution to the layer appears in the tangential velocity and is of width ϵ√ and amplitude O(ϵ√). Next we prove that the approximate solution stays close to the exact Navier-Stokes solution on a fixed time interval independent of ϵ. As an immediate corollary we show that the Navier-Stokes solution converges in L∞ in the small viscosity limit to the solution of the compressible Euler equations with normal velocity equal to zero on the boundary.
Genre hybridisation in the feminist short stories of Margo Lanagan & Synchronisation
Creators: name: Goldie, Sheriden
Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: This thesis explores how Margo Lanagan employs multiple genre conventions and tropes to create fictional worlds and new narrative discourses around issues of feminism, historical representation, national identities in her short fiction. It is comprised of research and a creative component. The creative component will implement the techniques and genres explored in the discussion of Lanagan’s short stories. Margo Lanagan is an Australian author whose fiction blends genres and appeals to both young adults and adults. Several scholarly essays have focused on her young adult novels; however, her short fiction has not received the same attention. This paper aims to begin closing this gap by examining Lanagan’s shorts stories, with a specific focus on how Lanagan manipulates multiple genre conventions to create narratives that resist easy genre classification. While the scholarship of science fiction and fantasy texts creates a false dichotomy between the modes, writers often combine genres, and sub-genres, from either side of this divide. Lanagan’s stories exemplify this trend as they all bridge science fiction and fantasy. In order to discuss these texts then, one must draw from both sides of the existing scholarship. Lanagan is a consciously feminist writer, and this is an aspect of the analysis of these narratives. It is fruitful to combine research approaches in order to explore the full breadth of Lanagan’s creative expression. This thesis examines a selection of Lanagan’s short fiction using close reading in combination with feminist theory and genre theory. These narratives build complex secondary worlds while also engaging with contemporary issues through their plots and characters. Through this investigation, this thesis will show how Lanagan manipulates genre at a textual level and what effect that manipulation has on how the narrative engages with social issues. This thesis's research is accompanied by a creative work titled “Synchronisation” and a short reflective essay discussing the interaction between the research and the creative process.

description: We consider physical properties of a superconductor with a recently proposed type of odd-frequency pairing that exhibits diamagnetic Meissner response ("odd-dia state"). Such a state was suggested in order to address stability issues arising in an odd-frequency superconducting state with paramagnetic Meissner response ("odd-para state"). Assuming the existence of an odd-dia state (due to a proper retarded interaction), we study its coexistence with an odd-para state. The latter is known to be generated as an induced superconducting component in, e.g., singlet superconductor/ferromagnet proximity structures or triplet superconductor/normal metal systems. Calculating the superfluid density of the mixed odd-para/odd-dia state and the Josephson current between the odd-para and odd-dia states, we find that the expressions for the currents in both cases have non-vanishing imaginary contributions and are therefore unphysical. We show that a realization of the odd-dia state implies the absence of a Hamiltonian description of the system, and suggest that there exists no physically realizable perturbation that could give rise to the spontaneous symmetry breaking necessary for an actual realization of the odd-dia superconducting state.

It is shown that, for a collection of positive charges on a pentagonal linkage, there is a unique critical point in the set of convex configurations which is the point of absolute minimum. This enables us to prove that two controlling charges are sufficient to navigate between any two convex configurations of a pentagonal linkage.

description: We introduce a method for obtaining new classes of free divisors from representations $V$ of connected linear algebraic groups $G$ where $\dim G = \dim V$, with $V$ having an open orbit. We give sufficient conditions that the complement of this open orbit, the “exceptional orbit variety”, is a free divisor (or a slightly weaker free* divisor) for “block representations” of both solvable groups and extensions of reductive groups by them. These are representations for which the matrix defined from a basis of associated “representation vector fields” on $V$ has block triangular form, with blocks satisfying certain nonsingularity conditions.

description: A natural atom placed into a cavity with time-dependent parameters can be parametrically excited due to the interaction with the quantized photon mode. One of the channels of such a process is the dynamical Lamb effect, induced by a nonadiabatic modulation of atomic level Lamb shift. However, in experiments with natural atoms it is quite difficult to isolate this effect from other mechanisms of atom excitation. We point out that a transmission line cavity coupled with a superconducting qubit (artificial macroscopic atom) provides a unique platform for the observation of the dynamical Lamb effect. A key idea is to exploit a dynamically tunable qubit-resonator coupling, which was implemented quite recently. By varying nonadiabatically the coupling, it is possible to parametrically excite a qubit through a nonadiabatic modulation of the Lamb shift, even if the cavity was initially empty. A dynamics of such a coupled system is studied within the Rabi model with time-dependent coupling constant and beyond the rotating wave approximation. An efficient method to increase the effect through the periodic and nonadiabatic switching of a qubit-resonator coupling energy is proposed.

description: The paper examines impact of open and distance education in prisoner's rehabilitation and reintegration in Enugu Maximum Custodial Centre, from 2011 to 2024. The paper adopted a descriptive research design while data were collected through survey (Questionnaires and oral interviews) and documentary sources. The sample size of the study is seventy-six (76) participants, made up of seventy (73) serving and former inmates/students as well as three (3) officials of the Custodial Centre selected using a purposive sampling method. Data collected from questionnaire were presented in tables, figures, percentages and frequencies. Data from interviews and documentary sources were analyzed using content analysis. The quantitative data generated were subjected to inferential statistical tool using multiple regression analysis with the aid of Statistical Package for Social Science (IBM SPSS) Software, version 22.0. The result showed that open and distance learning (ODL) has been effective and efficient in prisoners’ rehabilitation and reintegration and that challenges such as lack of adequate structures/classroom building for the program, lack of internet services, and lack of budgetary support, among others, hinder the program. The paper concludes that prisoner education and literacy programs such as ODL should be included in the nation’s education curriculum and made compulsory for prison inmates as part of their rehabilitation and reintegration programs
Unique Continuation for Quasimodes on Surfaces of Revolution: Rotationally invariant Neighbourhoods
Creators: name: Christianson, Hans
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: We introduce the definition of irreducible quasimodes, which are quasimodes with $h$-wavefront sets living on the smallest invariant sets in phase space. We prove a strong conditional unique continuation estimate for these quasimodes in rotationally invariant neighbourhoods on compact surfaces of revolution. The estimate states that irreducible Laplace quasimodes have $L^2$ mass bounded below by $C_\epsilon \lambda ^{-1 - \epsilon }$ for any $\epsilon >0$ on any open rotationally invariant neighbourhood which meets the semiclassical wavefront set of the quasimode. For an analytic manifold, we conclude the same estimate with a lower bound of $C_\delta \lambda ^{-1 + \delta }$ for some fixed $\delta >0$.

description: Exoplanets display incredible diversity, from planetary system architectures around Sun-like stars that are very different to our Solar System, to planets orbiting post-main sequence stars or stellar remnants. Recently the B-star Exoplanet Abundance STudy (BEAST) reported the discovery of at least two super-Jovian planets orbiting massive stars in the Sco Cen OB association. Whilst such massive stars do have Keplerian discs, it is hard to envisage gas giant planets being able to form in such hostile environments. We use N-body simulations of star-forming regions to show that these systems can instead form from the capture of a free-floating planet, or the direct theft of a planet from one star to another, more massive star. We find that this occurs on average once in the first 10Myr of an association's evolution, and that the semimajor axes of the hitherto confirmed BEAST planets (290 and 556au) are more consistent with capture than theft. Our results lend further credence to the notion that planets on more distant (>100au) orbits may not be orbiting their parent star.

description: We perform spatially dependent tuning of a GaInP photonic crystal cavity using a continuous wave violet laser. Local tuning is obtained by laser heating of the photonic crystal membrane. The cavity resonance shift is measured for different pump positions and for two ambient gases: helium and nitrogen. We find that the width of the temperature profile induced in the membrane depends strongly on the thermal conductivity of the ambient gas. For He gas a narrow spatial width of the temperature profile of 2.8 um is predicted and verified in experiment.

description: When elements of a measure-preserving action of Rd or Zd are selected in a random way, according to a stationary stochastic process, a.e. convergence of the averages of an LP function along the resulting orbits may almost surely hold, in every system; in such a case we call the sampling scheme universally representative. We show that i.i.d. integervalued sampling schemes are universally representative (with p > 1) if and only if they have nonzero mean, and we discuss a variety of other sampling schemes which have or lack this property.

description: The electrostatic interaction in ionic fluids is well-known to give rise to a characteristic phase behavior and structure. Sometimes its long range is proposed to single out the electrostatic potential over other interactions with shorter ranges. Here the importance of the range for the phase behavior and the structure of ionic fluids is investigated by means of grandcanonical Monte Carlo simulations of the lattice restricted primitive model (LRPM). The long-ranged electrostatic interaction is compared to various types of short-ranged potentials obtained by sharp and/or smooth cut-off schemes. Sharply cut off electrostatic potentials are found to lead to a strong dependence of the phase behavior and the structure on the cut-off radius. However, when combined with a suitable additional smooth cut-off, the short-ranged LRPM is found to exhibit quantitatively the same phase behavior and structure as the conventional long-ranged LRPM. Moreover, the Stillinger-Lovett perfect screening property, which is well-known to be generated by the long-ranged electrostatic potential, is also fulfilled by short-ranged LRPMs with smooth cut-offs. By showing that the characteristic phase behavior and structure of ionic fluids can also be found in systems with short-ranged potentials, one can conclude that the decisive property of the electrostatic potential in ionic fluids is not the long range but rather the valency dependence.

description: Computational approaches are beginning to be used to design dynamic visual identities fuelled by data and generative processes. In this work, we explore these computational approaches in order to generate a visual identity that creates bespoke letterings and images. We achieve this developing a generative design system that automatically assembles black and white visual modules. This system generates designs performing two main methods: (i) Assisted generation; and (ii) Automatic generation. Assisted generation method produces outputs wherein the placement of modules is determined by a configuration file previous defined. On the other hand, the Automatic generation method produces outputs wherein the modules are assembled to depict an input image. This system speeds up the process of design and deployment of one visual identity design as well as it generates outputs visual coherent among them. In this paper, we compressively describe this system and its achievements.

description: Functionals of the one-body reduced density matrix (1-RDM) are routinely minimized under Coleman's ensemble $N$-representability conditions. Recently, the topic of pure-state $N$-representability conditions, also known as generalized Pauli constraints, received increased attention following the discovery of a systematic way to derive them for any number of electrons and any finite dimensionality of the Hilbert space. The target of this work is to assess the potential impact of the enforcement of the pure-state conditions on the results of reduced density-matrix functional theory calculations. In particular, we examine whether the standard minimization of typical 1-RDM functionals under the ensemble $N$-representability conditions violates the pure-state conditions for prototype 3-electron systems. We also enforce the pure-state conditions, in addition to the ensemble ones, for the same systems and functionals and compare the correlation energies and optimal occupation numbers with those obtained by the enforcement of the ensemble conditions alone.

description: Cluster formation is a fundamental aspect of the equation of state (EOS) of warm and dense nuclear matter such as can be found in supernovae (SNe). Similar matter can be studied in heavy-ion collisions (HIC). We use the experimental data of Qin et al. [Phys. Rev. Lett. 108, 172701 (2012)] to test calculations of cluster formation and the role of in-medium modifications of cluster properties in SN EOSs. For the comparison between theory and experiment we use chemical equilibrium constants as the main observables. This reduces some of the systematic uncertainties and allows deviations from ideal gas behavior to be identified clearly. In the analysis, we carefully account for the differences between matter in SNe and HICs. We find that, at the lowest densities, the experiment and all theoretical models are consistent with the ideal gas behavior. At higher densities ideal behavior is clearly ruled out and interaction effects have to be considered. The contributions of continuum correlations are of relevance in the virial expansion and remain a difficult problem to solve at higher densities. We conclude that at the densities and temperatures discussed mean-field interactions of nucleons, inclusion of all relevant light clusters, and a suppression mechanism of clusters at high densities have to be incorporated in the SN EOS.

description: This systematic review provides an overview of the effects of menopausal symptom treatment options on palpitations, defined as feelings of missed or exaggerated heart beats, reported by perimenopausal and postmenopausal women. Guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, searches were conducted in PubMed, CINAHL and PsycINFO to identify articles meeting pre-specified inclusion criteria. Of 670 unique articles identified, 37 were included in the review. Treatments included drug therapies and non-drug therapies. Palpitations were studied as an outcome in 89% of articles and as an adverse effect in 11%. Articles provided mostly level II/III evidence due to their design and/or small sample sizes. Based on available evidence, no therapies can be fully recommended for clinical practice. Only some hormonal agents (e.g. estradiol) can be recommended with caution based on some positive evidence for reducing palpitation prevalence or severity. However, other drug therapies (e.g. moxonidine, atenolol), dietary supplementary treatments (e.g. isoflavones, Rheum rhaponticum, sage), cognitive-behavioral intervention and auricular acupressure cannot be recommended given the existing evidence. Additional well-designed randomized controlled treatment trials focusing on palpitations during the menopause transition as an inclusion criteria and outcome are needed to advance the field.
D3.5 - Report on Dynamic Data Assimilation methodology

description: This deliverable aims at describing a newly-developed methodology implemented by AUTh for the continuous update and refinement of numerical modelling results based on in-situ measurements. This method is based on a 3-D data assimilation protocol which supports fusion of data-streams both from micro weather stations installed at a number of selected demonstration pilots in Task 3.4 and from the networked unattended and low cost micro-climate stations developed within Task 3.5. More specifically, the data aggregated from the sensor network and delivered through the monitoring system are initially engaged with the simulated data and, as a second step, are analysed and fused (including aggregation, synchronization, calibration and assimilation) from a fully interoperable data management platform. In this way, localscale atmospheric and climate stressing on the CH of the selected demonstrations pilots which are in principle not resolved are explicitly introduced into the highresolution simulations.
ASYMMETRIC HYDROGENATION OFINDUSTRIALLY RELEVANT SUBSTRATES

description: This thesis is divided in two parts: In Part A (Chapters I to III), the studies on the asymmetric hydrogenation of substituted pyridines are described. These heteroaromatic compounds have proven very challenging to hydrogenate enantioselectively, however, the resulting chiral piperidines are of high industrial interest. In Chapter I, the state of the art and the mechanistic studies carried out on related N-heteroaromatic substrates are extensively discussed. In Chapter II, a new method for the asymmetric hydrogenation of 2-substitued pyridines is reported, together with complementary mechanistic studies that shed light on the origin of the enantioselectivity. In Chapter III, a method for the highly enantioselective hydrogenation of 3-substituted pyridines is disclosed. Furthermore, a deep mechanistic study reveals how this high level of stereocontrol can be achieved on substrates where no good results had been reported until now. Part B (Chapter IV to VI) is centered on the problems associated with the high prices of noble metals. Two different solutions have been envisioned in the scientific community to overcome this problem. The first one relies on the replacement of the more commonly used expensive metals for cheap and abundant 1st row transition metals, such as Fe, Co, Ni or Cu. The second approach consists in recycling or reusing the noble metals for more than one reaction. In this regard, tandem catalysis is a commonly applied methodology, where the same metal is used to catalyze at least two different reactions in one pot. In our case, we focused on developing an asymmetric version of the tandem olefin metathesis?hydrogenation. Chapter IV contains an introduction on the topic. In Chapter V and VI, the conversion of different Ru-olefin metathesis catalysts to efficient asymmetric hydrogenation and asymmetric transfer hydrogenation catalysts is described, respectively. These transformations have been subsequently applied to the tandem metathesis-asymmetric hydrogenation and to the metathesis-asymmetric transfer hydrogenation.

description: Coverage-guided fuzzing's aggressive, high-volume testing has helped reveal tens of thousands of software security flaws. While executing billions of test cases mandates fast code coverage tracing, the nature of binary-only targets leads to reduced tracing performance. A recent advancement in binary fuzzing performance is Coverage-guided Tracing (CGT), which brings orders-of-magnitude gains in throughput by restricting the expense of coverage tracing to only when new coverage is guaranteed. Unfortunately, CGT suits only a basic block coverage granularity -- yet most fuzzers require finer-grain coverage metrics: edge coverage and hit counts. It is this limitation which prohibits nearly all of today's state-of-the-art fuzzers from attaining the performance benefits of CGT. This paper tackles the challenges of adapting CGT to fuzzing's most ubiquitous coverage metrics. We introduce and implement a suite of enhancements that expand CGT's introspection to fuzzing's most common code coverage metrics, while maintaining its orders-of-magnitude speedup over conventional always-on coverage tracing. We evaluate their trade-offs with respect to fuzzing performance and effectiveness across 12 diverse real-world binaries (8 open- and 4 closed-source). On average, our coverage-preserving CGT attains near-identical speed to the present block-coverage-only CGT, UnTracer; and outperforms leading binary- and source-level coverage tracers QEMU, Dyninst, RetroWrite, and AFL-Clang by 2-24x, finding more bugs in less time.

description: The 21st century is characterized by the Fourth Industrial Revolution, with Computer Science at its core. As industrialization relies heavily on computer technology, the study of Computer Science has become central to modern education, particularly in universities. However, the integration of mathematics into Computer Science curricula has sparked debates among scholars. While some experts argue that Computer Science is inherently mathematical, others contend that its mathematical components are minimal, leading to the transformation of traditional mathematics courses like Numerical Methods and Discrete Mathematics into computer-specific versions. This study investigates the relationship between mathematics and Computer Science courses, examining whether differences exist in student performance based on the instructional approach (Blended Learning) and the type of university (public or private). The study involved 674 second-year Computer Science students from Enugu State, using the Mathematics Method Achievement Test (MMAT) and Computer Programming Achievement Test (CPAT) as data collection instruments. Results revealed no significant correlation between student achievements in Mathematics and Computer Science courses, although Blended Learning enhanced performance in both areas. Additionally, students from private universities outperformed their public university counterparts in Computer Science courses. The study recommends that the National Universities Commission (NUC) organize workshops to promote Blended Learning and reconsider the emphasis on mathematics in Computer Science curricula

description: Breast arterial calcification (BAC) is a common incidental finding on screening mammography. Recent evidence suggests that BAC is associated with cardiovascular disease (CVD). We systematically reviewed the associations between BAC and reproductive factors (menopausal status, hormone replacement therapy [HRT] use, oral contraceptive [OC] use and parity). MEDLINE and EMBASE databases, references of relevant papers and Web of Science were searched up to February 2020 for English-language studies that evaluated these associations. Study quality were determined and a random effects model was used to assess these associations. Nineteen observational studies (n = 47,249; three cohort studies, seven case–control studies, nine cross-sectional studies) were included. BAC was associated with menopause (nine studies; n = 15,870; odds ratio [OR] 2.67; 95% confidence interval [CI] 1.50–4.77) and parity (seven studies; n = 27,728; OR 2.50; 95% CI 1.68–3.71) and inversely with HRT use (10 studies; n = 33,156; OR 0.57; 95% CI 0.40–0.80). No association was found with OC use. Eleven studies were considered good in quality. Marked heterogeneity existed across all analyses. BAC is associated with HRT use, menopause and parity. However, careful interpretation is required as marked heterogeneity existed across all analyses. Traditional cardiovascular risk factors may need to be taken into account in future investigations of associations between BAC and reproductive factors. CRD42020141644.
