description: This is a scanned copy of a document, including diagrams and a photograph, of a trend assessment of Sneeuberg Hut Plot 1 in the Cederberg State Forest, site 3219AC/2/1/1. The Jonkershoek Forestry Research Center (part of the former South African Forestry Research Institute) was established in 1935 at Jonkershoek, near Stellenbosch, under the directorship of Dr C. L. Wicht. The initial aim was to determine how forestry activities in state plantations would affect climate, water conservation and erosion, and was later expanded to include studies of fynbos ecology, fire and alien species. Studies from the 1930s to the early 1990s saw the accumulation of a large amount of data dealing with fire experiments, detailed vegetation plot surveys, rare plant surveys and ecological studies, hydrological studies and the development of management plans for catchments around the Western Cape. SAEON now houses the archive of data collected by the Jonkershoek Forestry Research Center, which was originally held by the Council for Scientific and Industrial Research (CSIR).

description: We examine the adsorption of a single Ni atom on a monolayer of MgO on a Ag substrate using DFT and DFT+U computational approaches. We find that the electronic and magnetic properties vary considerably across the three binding sites of the surface. Two of the binding sites are competitive in energy, and the preferred site depends on the strength of the on-site Coulomb interaction U. These results can be understood in terms of the competition between bonding and magnetism for surface adsorbed transition metal atoms. Comparisons are made with a recent experimental and theoretical study of Co on MgO/Ag, and implications for scanning tunneling microscopy experiments on the Ni system are discussed.

description: We explore possible asymmetric dark matter models using CP violating scatterings to generate an asymmetry. In particular, we introduce a new model, based on DM fields coupling to the SM Higgs and lepton doublets, a neutrino portal, and explore its UV completions. We study the CP violation and asymmetry formation of this model, to demonstrate that it is capable of producing the correct abundance of dark matter and the observed matter-antimatter asymmetry. Crucial to achieving this is the introduction of interactions which violate CP with a $T^{2}$ dependence.

description: We study the extended thermodynamics, obtained by considering the cosmological constant as a thermodynamic variable, of STU black holes in 4-dimensions in the fixed charge ensemble. The associated phase structure is conjectured to be dual to an RG-flow on the space of field theories. We find that for some charge configurations the phase structure resembles that of a Van der Waals gas: the system exhibits a family of first order phase transitions ending in a second order phase transition at a critical temperature. We calculate the holographic entanglement entropy for several charge configurations and show that for the cases where the gravity background exhibits Van der Waals behavior, the entanglement entropy presents a transition at the same critical temperature. To further characterize the phase transition we calculate appropriate critical exponents and show that they coincide. Thus, the entanglement entropy successfully captures the information of the extended phase structure. Finally, we discuss the physical interpretation of the extended space in terms of the boundary QFT and construct various holographic heat engines dual to STU black holes.

Distorted black holes

description: The study of black holes and their interactions and the extraction of gravitational waves become of primary importance from both - the astrophysical and theoretical points of view now that the first gravitational detectors have started operating; gravitational waves, while certainly extremely weak, are also extremely pervasive and thus a novel and very promising way of exploring the universe. Space-times containing highly distorted black holes will generally have strong time-dependent gravitational fields and presumably provide the strongest sources of gravitational waves in the universe. This work focuses on two fundamental problems in modern numerical relativity: (1) Creating valid initial data of non-perturbative distorted black hole space-times for numerical evolution, and (2) extracting the radiation quantities in a coordinate independent way, using the Newman-Penrose formalism. I first consider the initial data for such distorted black hole space-times, prescribing them successfully in a simplified situation of superimposed time symmetric Brill waves, and leading the way to more general initial data which corresponds to rotating black holes. To drop the assumption of time symmetric initial hypersurfaces will be subject of future work. Next I move to the numerical evolution and introduce a simple but stable way to perform excision in spherical coordinates. Finally, I extract the gravitational wave signal from the numerical simulations, using the Newman-Penrose formalism, in particular the Weyl scalars. I adopt a particular frame where the Weyl scalars acquire physical meaning, and can be directly associated with the waveform. Moreover, I derive a formula to calculate the energy carried away by the wave. Comparison of the even and odd parity waveforms of our non-perturbation approach with the metric perturbation approaches such as Regge-Wheeler [1], Zerilli [2] and Teukolsky [3] will partly be discussed and partly be subject of future work

Beliefs about seeking and receiving help: Measurement of the recipient's perspective on helping behavior

Subjects: Social psychology

description: To fully understand the nature of help, we need to study it from both the helper’s and the recipient’s perspectives, yet the recipient's perspective of help has been often overlooked. This study aimed to identify and measure people’s general beliefs about seeking and receiving help. The first study used thematic analysis to identify broad belief themes from 81 participants’ written thoughts and experiences of help. The five belief themes were then used to generate a pool of items to measure general beliefs about seeking and receiving help. The second study used a split-half sample to assess the factor structure and identify items to remove using EFA and CFA. Ten distinct, though related, subscales of the five belief themes were retained, and these items were then assessed through a content validation study, which supported the definitional correspondence and distinctiveness of the items to their scales. While further validation of the measure needs to be conducted, there is promising evidence of the scale’s content coverage compared to previous scales, reliability, and content validity of the identified subscales.

description: The African Union is made up of 55 Member States representing all the countries on the African continent. These Member States are divided into five geographic regions. AU aims to achieve greater unity, cohesion and solidarity among the African countries and African nations.The African Union is a key driving force for the continent’s political and economic development, its primary purpose being African integration and increased cooperation among African countries, with a view to achieving peace, security, and prosperity for all the people of the continent.Historically India’s outreach to Africa began in 2008 although China before India had first reached Africa in 2000 & since the formation of Forum on China Africa Cooperation (FOCAC) has come a long way indicating evolving Chinese interests in the African continent.However, with her shrewd move to include the African Union in the G20 grouping, India has pitched itself as a leader of the developing and underdeveloped countries, it is opined. It is said the move is in sync with India’s aspiration for Permanent Membership of the UNSC for which India is keen to garner support from Africa, which has 55 votes.

description: We report on four large filament eruptions (FEs) from solar cycles 23 and 24 that were associated with large solar energetic particle (SEP) events and interplanetary type II radio bursts. The post-eruption arcades corresponded to mostly C-class soft X-ray enhancements, but an M1.0 flare was associated with one event. However, the associated coronal mass ejections (CMEs) were fast (speeds about 1000 km/s) and appeared as halo CMEs in the coronagraph field of view. The interplanetary type II radio bursts occurred over a wide wavelength range indicating the existence of strong shocks throughout the inner heliosphere. No metric type II bursts were present in three events, indicating that the shocks formed beyond 2 to 3 Rs. In one case, there was a metric type II burst with low starting frequency indicating a shock formation height of about 2 Rs. The FE-associated SEP events did have softer spectra (spectral index greater than 4) in the 10 to 100 MeV range, but there were other low-intensity SEP events with spectral indices >/=4. Some of these events are likely FE-SEP events, but were not classified so in the literature because they occurred close to active regions. Some were definitely associated with large active region flares, but the shock formation height was large. We definitely find a diminished role for flares and complex type III burst durations in these large SEP events. Fast CMEs and shock formation at larger distances from the Sun seem to be the primary characteristics of the FE-associated SEP events.

Dispersion in rectangular networks: effective diffusivity and large-deviation rate function

description: The dispersion of a diffusive scalar in a fluid flowing through a network has many applications including to biological flows, porous media, water supply and urban pollution. Motivated by this, we develop a large-deviation theory that predicts the evolution of the concentration of a scalar released in a rectangular network in the limit of large time $t \gg 1$. This theory provides an approximation for the concentration that remains valid for large distances from the centre of mass, specifically for distances up to $O(t)$ and thus much beyond the $O(t^{1/2})$ range where a standard Gaussian approximation holds. A byproduct of the approach is a closed-form expression for the effective diffusivity tensor that governs this Gaussian approximation. Monte Carlo simulations of Brownian particles confirm the large-deviation results and demonstrate their effectiveness in describing the scalar distribution when $t$ is only moderately large.

description: Recent improvements in control of quantum systems make it seem feasible to finally build a quantum computer within a decade. While it has been shown that such a quantum computer can in principle solve certain small electronic structure problems and idealized model Hamiltonians, the highly relevant problem of directly solving a complex correlated material appears to require a prohibitive amount of resources. Here, we show that by using a hybrid quantum-classical algorithm that incorporates the power of a small quantum computer into a framework of classical embedding algorithms, the electronic structure of complex correlated materials can be efficiently tackled using a quantum computer. In our approach, the quantum computer solves a small effective quantum impurity problem that is self-consistently determined via a feedback loop between the quantum and classical computation. Use of a quantum computer enables much larger and more accurate simulations than with any known classical algorithm, and will allow many open questions in quantum materials to be resolved once a small quantum computer with around one hundred logical qubits becomes available.

CHARACTERIZING INTERACTIONS BETWEEN CANCER CELLS AND THE EXTRACELLULAR MATRIX IN METASTATIC BREAST CANCER THROUGH FIBRONECTIN ACCUMULATION

description: Metastases are responsible for approximately 90% of all cancer-related deaths, with metastatic breast cancer (BC) holding a 5-year survival rate of only 27%. Recent research has highlighted a complex dynamic between cancer cells and the tumor microenvironment as essential for the formation of macrometastases. Within this field, tissue stiffening through matrix accumulation and altered matrix organization at the primary tumor site were recently linked with sustained proliferation and increased migration of tumor cells. Separately, elevated levels of the glycoprotein, fibronectin, were correlated to poor patient survival in BC and were linked to enhanced seeding of disseminated tumor cells at metastatic sites. Through my doctoral work, we have identified several mechanisms through which accumulated fibronectin impacts the metastatic potential of BC cells. First, we identified a transient increase in extracellular fibronectin in the lungs, which peaked before overt metastasis, coupled with a non-transient increase in total lung volume. To better recapitulate physiological conditions, we then developed a novel magnetically-actuated platform with the ability to apply tensile strain on cells at various amplitudes and frequencies in a high-throughput multi-well culture plate using suspended fibrillar fibronectin for 3D cell culture that is not reliant on a synthetic substrate. Using this as a biomimetic lung model, we found that cyclic mechanical force acted as a suppressor of cancer cell growth in a biomimetic lung model, implicating the accumulation and reorganization of extracellular matrix as an attempt by the cancer cells to alter the mechanical properties of the lung tissue and resist entering dormancy. However, our results showed that BC cells could not organize extracellular fibronectin independently. Instead, BC cells altered the accumulation and architecture of fibronectin by conditioning fibroblasts through soluble factors and extracellular vesicles. We observed that the fibronectin produced by conditioned fibroblasts varied as an effect of both the method of conditioning and the phenotype of the BC cell as the conditioning source. Taken together, these results have increased our knowledge of the relationship between disseminated breast cancer cells, fibroblasts, and fibronectin architecture in the early metastatic lung niche that paves the way for further investigation on targeting disseminated BC cells during early disease intervention in order to inhibit later overt metastatic outgrowth.

description: Gender inequities can be partly traced back to gender differences in working time arrangements. In fact, it is established knowledge that women as compared to men are more (less) likely to work part-time (overtime). Based on social role theory, however, we also expect gender differences among part-time and overtime workers, such that women and men differ in why they work part-time or overtime. In a preregistered and highly powered study conducted in Germany (N = 3,844–17,361, depending on the analysis), we observed that, on average, women were more likely than men to work part-time (i.e., fewer than 35 hours per week) because of personal or family obligations. Moreover, in comparison to men, women were less likely to work overtime (i.e., at least two hours per week) to attain additional income, but more likely to work overtime to step in for colleagues. Altogether, people had “gendered” reasons to work certain hours. Furthermore, as people’s paid working time arrangements are intertwined with their lives outside of the workplace, we examined women’s and men’s work–life interface and observed that women (as compared to men) deemed it less acceptable to be available for work-related issues during leisure time. We discuss implications for future theorizing and for practitioners who aim to design work schedules that consider the different lived experiences of women and men.

description: We have used Minor Planet Center data and tools to explore the discovery circumstances and properties of the currently known population of over 10,000 NEAs, and to quantify the challenges for follow-up from ground-based telescopes. The increasing rate of discovery has grown to ~1,000/year as surveys have become more sensitive, by 1mag every ~7.5 years. However, discoveries of large (H =< 22) NEAs have remained stable at ~365/year over the past decade, at which rate the 2005 Congressional mandate to find 90% of 140m NEAs will not be met before 2030. Meanwhile, characterization is falling farther behind: Fewer than 10% of NEAs are well characterized in terms of size, rotation periods, and spectra, and at current rates of follow-up it will take about a century to determine them even for the known population. Over 60% of NEAs have an orbital uncertainty parameter, U >= 4, making reacquisition more than a year following discovery difficult; for H > 22 this fraction is over 90%. We argue that rapid follow-up will be essential to characterize newly-discovered NEAs. Most new NEAs are found within 0.5mag of peak brightness and fade quickly, typically by 0.5/3.5/5mag after 1/4/6 weeks. About 80% have synodic periods of <3 years that bring them close to Earth several times a decade. However, follow-up observations on subsequent apparitions will be near impossible for the bulk of new discoveries, as these will be H > 22 NEAs that tend to return 100 times fainter. We show that for characterization to keep pace with discovery would require: Visible spectroscopy within days with a dedicated >2m telescope; long-arc astrometry, used also for phase curves, with a >4m telescope; and fast-cadence (= 4m telescope. For the already-known large (H =< 22) NEAs, subsequent-apparition spectroscopy, astrometry, and photometry could be done with 1-2m telescopes.

description: The remarkable optoelectronic, and especially photovoltaic performance of hybrid-organic-inorganic perovskite (HOIP) materials drives efforts to connect materials properties to this performance. From nano-indentation experiments on solution-grown single crystals we obtain elastic modulus and nano-hardness values of APbX3 (A = Cs, CH3NH3 and X = I, Br). The Youngs moduli are about 14, 19.5 and 16 GPa, for CH3NH3PbI3, CH3NH3PbBr3 and CsPbBr3, respectively, lending credence to theoretically calculated values. We discuss possible relevance of our results to suggested self-healing, ion diffusion and ease of manufacturing. Using our results, together with literature data on elastic moduli, we classified HOIPs amongst relevant materials groups, based on their elasto-mechanical properties.

description: We have carried out wall-resolved unstructured fully-compressible Navier--Stokes simulations of a complete standing-wave thermoacoustic piezoelectric (TAP) engine model inspired by the experimental work of Smoker et al. (2012). The model is axisymmetric and comprises a 51 cm long resonator divided into two sections: a small diameter section enclosing a thermoacoustic stack, and a larger diameter section capped by a piezoelectric diaphragm tuned to the thermoacoustically amplified mode (388 Hz). The diaphragm is modelled with multi-oscillator broadband time-domain impedance boundary conditions (TDIBCs), providing higher fidelity over single-oscillator approximations. Simulations are first carried out to the limit cycle without energy extraction. The observed growth rates are shown to be grid-convergent and are verified against a numerical dynamical model based on Rott's theory. The latter is based on a staggered grid approach and allows jump conditions in the derivatives of pressure and velocity in sections of abrupt area change and the inclusion of linearized minor losses. The stack geometry maximizing the growth rate is also found. At the limit cycle, thermoacoustic heat leakage and frequency shifts are observed, consistent with experiments. Upon activation of the piezoelectric diaphragm, steady acoustic energy extraction and a reduced pressure amplitude limit cycle are obtained. A heuristic closure of the limit cycle acoustic energy budget is presented, supported by the linear dynamical model and the nonlinear simulations. The developed high-fidelity simulation framework provides accurate predictions of thermal-to-acoustic and acoustic-to-mechanical energy conversion (via TDIBCs), enabling a new paradigm for the design and optimization of advanced thermoacoustic engines.

description: We perform uniformly sampled large-scale cosmological simulations including magnetic fields with the moving mesh code AREPO. We run two sets of MHD simulations: one including adiabatic gas physics only; the other featuring the fiducial feedback model of the Illustris simulation. In the adiabatic case, the magnetic field amplification follows the $B \propto ρ^{2/3}$ scaling derived from `flux-freezing' arguments, with the seed field strength providing an overall normalization factor. At high baryon overdensities the amplification is enhanced by shear flows and turbulence. Feedback physics and the inclusion of radiative cooling change this picture dramatically. In haloes, gas collapses to much larger densities and the magnetic field is amplified strongly and to the same maximum intensity irrespective of the initial seed field of which any memory is lost. At lower densities a dependence on the seed field strength and orientation, which in principle can be used to constrain models of cosmic magnetogenesis, is still present. Inside the most massive haloes magnetic fields reach values of $\sim 10-100\,\,{\rm μG}$, in agreement with galaxy cluster observations. The topology of the field is tangled and gives rise to rotation measure signals in reasonable agreement with the observations. However, the rotation measure signal declines too rapidly towards larger radii as compared to observational data.

description: We report the discovery of K2-31b, the first confirmed transiting hot Jupiter detected by the K2 space mission. We combined K2 photometry with FastCam lucky imaging and FIES and HARPS high-resolution spectroscopy to confirm the planetary nature of the transiting object and derived the system parameters. K2-31b is a 1.8-Jupiter-mass planet on an 1.26-day-orbit around a G7\,V star ($M_\star=0.91$~\Msun, $R_\star=0.78$~\Rsun). The planetary radius is poorly constrained (0.7$

description: The character of star formation is intimately related to the supersonic magnetohydrodynamic (MHD) turbulent dynamics of the molecular clouds in which stars form. A significant amount of the turbulent energy dissipates in low velocity shocks. Fast and slow MHD shocks differ in how they compress and heat the molecular gas, and so their radiative signatures reveal distinct physical conditions. We use a two-fluid model to compare one-dimensional fast and slow MHD shocks propagating at low speeds (a few km/s). Fast shocks are magnetically driven, forcing ion species to stream through the neutral gas ahead of the shock front. This magnetic precursor heats the gas sufficiently to create a large, warm transition zone where all the fluid variables smoothly change in the shock front. In contrast, slow shocks are driven by gas pressure, and neutral species collide with ion species in a thin hot slab that closely resembles an ordinary gas dynamic shock. We consider shocks at velocities $v_s = 2$-$4$ km/s and preshock Hydrogen nuclei densities $n_\mathrm{H} = 10^2$-$10^4$ cm$^{-3}$. We include a simple oxygen chemistry and cooling by CO, H$_2$ and H$_2$O. CO rotational lines above $J = 6\to 5$ are more strongly excited in slow shocks. These slow shock signatures may have already been observed in infrared dark clouds in the Milky Way.

description: The successful implementation of Spectral Matching Measures (SMMs) often plays a crucial role in material discrimination and classification using hyperspectral dataset. The commonly exploited SMMs, such as Spectral Angle Mapper (SAM), Spectral Information Divergence (SID), and their hybrid, i.e., SIDSAMtan, show limited discrimination ability while discriminating spectrally similar materials. This study presents three new effective SMMs named Dice Spectral Similarity Coefficient (DSSC), Kumar–Johnson Spectral Similarity Coefficient (KJSSC), and a hybrid of DSSC and KJSSC, i.e., KJDSSCtan, for accurate discrimination of spectrally similar materials. A wide range of hyperspectral datasets of minerals and vegetation acquired under laboratory and real atmospheric conditions were used to compare and evaluate the performance of newly proposed and existing SMMs using Relative Spectral Discrimination Power (RSDPW) statistics. We also assessed the discrimination ability of the proposed and existing SMMs using spectra of selected minerals and vegetation species with an added component of random noise and linearly synthesized mixed spectra. An in-depth comparison and evaluation of different SMMs demonstrated that the discrimination power of the proposed SMMs is significantly higher than existing SMMs. The proposed SMMs also outperform existing SMMs when discriminating noisy and linearly synthesized mixed counterparts. The KJSSC and DSSC show similar efficacy in discriminating spectra of minerals and vegetation, whereas their hybrid measure, i.e., KJDSSCtan shows significantly higher spectral discrimination ability. Therefore, the newly proposed hybrid measure, i.e., KJDSSCtan is recommended over existing SMMs for successful material discrimination and classification using hyperspectral data.

description: This is a scanned copy of a photo plot of Riviersonderend, Langeberg, site 3319DC/2. The Jonkershoek Forestry Research Center (part of the former South African Forestry Research Institute) was established in 1935 at Jonkershoek, near Stellenbosch, under the directorship of Dr C. L. Wicht. The initial aim was to determine how forestry activities in state plantations would affect climate, water conservation and erosion, and was later expanded to include studies of fynbos ecology, fire and alien species. Studies from the 1930s to the early 1990s saw the accumulation of a large amount of data dealing with fire experiments, detailed vegetation plot surveys, rare plant surveys and ecological studies, hydrological studies and the development of management plans for catchments around the Western Cape. SAEON now houses the archive of data collected by the Jonkershoek Forestry Research Center, which was originally held by the Council for Scientific and Industrial Research (CSIR).
Appearance of the prolate and the toroidal magnetic field dominated stars - Analytic approach

description: We have analyzed magnetized equilibrium states and showed a condition for appearance of the prolate and the toroidal magnetic field dominated stars by analytic approaches. Both observations and numerical stability analysis support that the magnetized star would have the prolate and the large internal toroidal magnetic fields. In this context, many investigations concerning magnetized equilibrium states have tried to obtain the prolate and the toroidal dominant solutions, but many of them have failed to obtain such configurations. Since the Lorentz force is a cross product of current density and magnetic field, the prolate shaped configurations and the large toroidal magnetic fields in stars require a special relation between current density and the Lorentz force. We have analyzed simple analytical solutions and found that the prolate and the toroidal dominant configuration require non force-free toroidal current density that flows in the opposite direction with respect to the bulk current within the star. Such current density results in the Lorentz force which makes the stellar shape prolate. Satisfying this special relation between the current density and the Lorentz force is a key for appearance of the prolate and the toroidal magnetic field dominated magnetized star.
