description: Lattice calculations of the form factors for $\bar{B}\to D^{(*)}\ell\barν$ decays can be used to extract the CKM matrix element $|V_{cb}|$. The Oktay-Kronfeld action is a highly improved version of the Fermilab action, which systematically reduces heavy quark discretization effects through $\mathcal{O}(λ^3)$ in HQET power counting, for heavy-light meson quantities. To calculate $\bar{B}\rightarrow D^{(*)}\ell \barν$ semi-leptonic form factors using Oktay-Kronfeld heavy quarks, we need to improve the heavy quark currents to the same level. We report our progress in calculating the improvement coefficients for currents composed of bottom and charm quarks. Our results presented in this paper are preliminary.

description: We continue to explore the scaling transformation in the reduced action formalism of gravity models. As an extension of our construction, we consider the extended forms of the Smarr relation for various black holes, adopting the cosmological constant as the bulk pressure as in some literatures on black holes. Firstly, by using the quasi-local formalism for charges, we show that, in a general theory of gravity, the volume in the black hole thermodynamics could be defined as the thermodynamic conjugate variable to the bulk pressure in such a way that the first law can be extended consistently. This, so called, thermodynamic volume can be expressed explicitly in terms of the metric and field variables. Then, by using the scaling transformation allowed in the reduced action formulation, we obtain the extended Smarr relation involving the bulk pressure and the thermodynamic volume. In our approach, we do not resort to Euler's homogeneous scaling of charges while incorporating the would-be hairy contribution without any difficulty.

description: We present the detection of supermassive black holes (BHs) in two Virgo ultracompact dwarf galaxies (UCDs), VUCD3 and M59cO. We use adaptive optics assisted data from the Gemini/NIFS instrument to derive radial velocity dispersion profiles for both objects. Mass models for the two UCDs are created using multi-band Hubble Space Telescope (HST) imaging, including the modeling of mild color gradients seen in both objects. We then find a best-fit stellar mass-to-light ratio ($M/L$) and BH mass by combining the kinematic data and the deprojected stellar mass profile using Jeans Anisotropic Models (JAM). Assuming axisymmetric isotropic Jeans models, we detect BHs in both objects with masses of $4.4^{+2.5}_{-3.0} \times 10^6$ $M_{\odot}$ in VUCD3 and $5.8^{+2.5}_{-2.8} \times 10^6$ $M_{\odot}$ in M59cO (3$σ$ uncertainties). The BH mass is degenerate with the anisotropy parameter, $β_z$; for the data to be consistent with no BH requires $β_z = 0.4$ and $β_z = 0.6$ for VUCD3 and M59cO, respectively. Comparing these values with nuclear star clusters shows that while it is possible that these UCDs are highly radially anisotropic, it seems unlikely. These detections constitute the second and third UCDs known to host supermassive BHs. They both have a high fraction of their total mass in their BH; $\sim$13% for VUCD3 and $\sim$18% for M59cO. They also have low best-fit stellar $M/L$s, supporting the proposed scenario that most massive UCDs host high mass fraction BHs. The properties of the BHs and UCDs are consistent with both objects being the tidally stripped remnants of $\sim$10$^9$ M$_\odot$ galaxies.

description: Planar photonic nanostructures have recently attracted a great deal of attention for quantum optics applications. In this article, we carry out full 3D numerical simulations to fully account for all radiation channels and thereby quantify the coupling efficiency of a quantum emitter embedded in a photonic-crystal waveguide. We utilize mixed boundary conditions by combining active Dirichlet boundary conditions for the guided mode and perfectly-matched layers for the radiation modes. In this way, the leakage from the quantum emitter to the surrounding environment can be determined and the spectral and spatial dependence of the coupling to the radiation modes can be quantified. The spatial maps of the coupling efficiency, the $β$-factor, reveal that even for moderately slow light, near-unity $β$ is achievable that is remarkably robust to the position of the emitter in the waveguide. Our results show that photonic-crystal waveguides constitute a suitable platform to achieve deterministic interfacing of a single photon and a single quantum emitter, which has a range of applications for photonic quantum technology.

description: Single-shot real-time characterization of optical waveforms with sub-picosecond resolution is essential for investigating various ultrafast optical dynamics. However, the finite temporal recording length of current techniques hinders comprehensive understanding of many intriguing ultrafast optical phenomena that evolve over a time scale much longer than their fine temporal details. Inspired by the space-time duality and by stitching of multiple microscopic images to achieve a larger field of view in the spatial domain, here a panoramic-reconstruction temporal imaging (PARTI) system is devised to scale up the temporal recording length without sacrificing the resolution. As a proof-of-concept demonstration, the PARTI system is applied to study the dynamic waveforms of slowly-evolved dissipative Kerr solitons in an ultrahigh-Q microresonator. Two 1.5-ns-long comprehensive evolution portraits are reconstructed with 740-fs resolution and dissipative Kerr soliton transition dynamics, in which a multiplet soliton state evolves into stable singlet soliton state, are depicted.

description: There is a strong interest to attach nanoparticles non-covalently to one-dimensional systems like boron nitride nanotubes to form composites. The combination of those materials might be used for catalysis, in solar cells, or for water splitting. Additionally, the fundamental aspect of charge transfer between the components can be studied in such systems. We report on the synthesis and characterization of nanocomposites based on semiconductor nanoparticles attached directly and non-covalently to boron nitride nanotubes. Boron nitride nanotubes were simply integrated into the colloidal synthesis of the corresponding nanoparticles. With PbSe, CdSe, and ZnO nanoparticles a wide range of semiconductor bandgaps from the near infrared to the ultra violet range was covered. A high surface coverage of the boron nitride nanotubes with these semiconducting nanoparticles was achieved, while it was found that a similar in-situ approach with metallic nanoparticles does not lead to proper attachment. In addition, possible models for the underlying attachment mechanisms of all investigated nanoparticles are presented. To emphasize the new possibilities that boron nitride nanotubes offer as a support material for semiconductor nanoparticles we investigated the fluorescence of BN-CdSe composites. In contrast to CdSe nanoparticles attached to carbon nanotubes, where the fluorescence is quenched, particles attached to boron nitride nanotubes remain fluorescent. With our versatile approaches we expand the library of BN-nanoparticle composites that present an interesting, electronically non-interacting complement to the widely applied carbon nanotube-nanoparticle composite materials.

description: Internal gravity waves play a primary role in geophysical fluids: they contribute significantly to mixing in the ocean and they redistribute energy and momentum in the middle atmosphere. Until recently, most studies were focused on plane wave solutions. However, these solutions are not a satisfactory description of most geophysical manifestations of internal gravity waves, and it is now recognized that internal wave beams with a confined profile are ubiquitous in the geophysical context. We will discuss the reason for the ubiquity of wave beams in stratified fluids, related to the fact that they are solutions of the nonlinear governing equations. We will focus more specifically on situations with a constant buoyancy frequency. Moreover, in light of recent experimental and analytical studies of internal gravity beams, it is timely to discuss the two main mechanisms of instability for those beams. i) The Triadic Resonant Instability generating two secondary wave beams. ii) The streaming instability corresponding to the spontaneous generation of a mean flow.

description: Jets from supermassive black holes in the centres of galaxy clusters are a potential candidate for moderating gas cooling and subsequent star formation through depositing energy in the intra-cluster gas. In this work, we simulate the jet-intra-cluster medium interaction using the moving-mesh magnetohydrodynamics code Arepo. Our model injects supersonic, low density, collimated and magnetised outflows in cluster centres, which are then stopped by the surrounding gas, thermalise and inflate low-density cavities filled with cosmic-rays. We perform high-resolution, non-radiative simulations of the lobe creation, expansion and disruption, and find that its dynamical evolution is in qualitative agreement with simulations of idealised low-density cavities that are dominated by a large-scale Rayleigh-Taylor instability. The buoyant rising of the lobe does not create energetically significant small-scale chaotic motion in a volume-filling fashion, but rather a systematic upward motion in the wake of the lobe and a corresponding back-flow perpendicular to it. We find that, overall, 50 per cent of the injected energy ends up in material which is not part of the lobe, and about 25 per cent remains in the inner 100 kpc. We conclude that jet-inflated, buoyantly rising cavities drive systematic gas motions which play an important role in heating the central regions, while mixing of lobe material is sub-dominant. Encouragingly, the main mechanisms responsible for this energy deposition can be modelled already at resolutions within reach in future, high-resolution cosmological simulations of galaxy clusters.

description: This study aimed to quantitatively examine how the addition of a strong or weak nucleophile (1.0 mol/L) to a soda cooking treatment (1.0 mol/L NaOH) at 150 °C affects the disappearance and condensation reactions of a simple phenolic lignin model compound, vanillyl alcohol (Va). All the observed phenomena could basically be attributed to the adduct formation of each reagent with the quinone methide intermediate derived from Va (QMVa) and the stabilization of the adduct. The adduct is irreversibly stabilized to be its conjugate base when the reagent was MeNH2 or Me2NH, resulting in the accumulation of the adduct and consequent consumption of QMVa without the reformation of Va from QMVa and condensation reactions of Va with QMVa. The adduct is not stabilized to be its conjugate base and reproduce QMVa when the reagent was Me3N, CO32¯, or SO42¯ (the sodium salt), resulting in the increased concentration of QMVa to promote the condensation reactions of Va with QMVa. These suppressive and promotive effects were more visible in the same treatment of Va with each nucleophile without the addition of NaOH, in which the concentration of hydroxide anion was low.

description: We address the important question of whether the newly discovered exoplanet, Proxima Centauri b (PCb), is capable of retaining an atmosphere over long periods of time. This is done by adapting a sophisticated multi-species MHD model originally developed for Venus and Mars, and computing the ion escape losses from PCb. The results suggest that the ion escape rates are about two orders of magnitude higher than the terrestrial planets of our Solar system if PCb is unmagnetized. In contrast, if the planet does have an intrinsic dipole magnetic field, the rates are lowered for certain values of the stellar wind dynamic pressure, but they are still higher than the observed values for our Solar system's terrestrial planets. These results must be interpreted with due caution, since most of the relevant parameters for PCb remain partly or wholly unknown.

description: We study the evolution of altruistic behaviour under a model where individuals choose to cooperate by comparing a set of continuous phenotype tags. Individuals play a donation game and only donate to other individuals that are sufficiently similar to themselves in a multidimensional phenotype space. We find the generic maintenance of robust altruism when phenotypes are multidimensional. Selection for altruism is driven by the coevolution of individual strategy and phenotype; altruism levels shape the distribution of individuals in phenotype space. Low donation rates induce a phenotype distribution that renders the population vulnerable to the invasion of altruists, whereas high donation rates prime a population for cheater invasion, resulting in cyclic dynamics that maintain substantial levels of altruism. Altruism is therefore robust to invasion by cheaters in the long term in this model. Furthermore, the shape of the phenotype distribution in high phenotype dimension allows altruists to better resist the invasion by cheaters, and as a result the amount of donation increases with increasing phenotype dimension. We also generalize previous results in the regime of weak selection to two competing strategies in continuous phenotype space, and show that success under weak selection is crucial to success under strong selection in our model. Our results support the viability of a simple similarity-based mechanism for altruism in a well-mixed population.

description: Stars form in cold molecular clouds. However, molecular gas is difficult to observe because the most abundant molecule (H2) lacks a permanent dipole moment. Rotational transitions of CO are often used as a tracer of H2, but CO is much less abundant and the conversion from CO intensity to H2 mass is often highly uncertain. Here we present a new method for estimating the column density of cold molecular gas (Sigma_gas) using optical spectroscopy. We utilise the spatially resolved H-alpha maps of flux and velocity dispersion from the Sydney-AAO Multi-object Integral-field spectrograph (SAMI) Galaxy Survey. We derive maps of Sigma_gas by inverting the multi-freefall star formation relation, which connects the star formation rate surface density (Sigma_SFR) with Sigma_gas and the turbulent Mach number (Mach). Based on the measured range of Sigma_SFR = 0.005-1.5 M_sol/yr/kpc^2 and Mach = 18-130, we predict Sigma_gas = 7-200 M_sol/pc^2 in the star-forming regions of our sample of 260 SAMI galaxies. These values are close to previously measured Sigma_gas obtained directly with unresolved CO observations of similar galaxies at low redshift. We classify each galaxy in our sample as 'Star-forming' (219) or 'Composite/AGN/Shock' (41), and find that in Composite/AGN/Shock galaxies the average Sigma_SFR, Mach, and Sigma_gas are enhanced by factors of 2.0, 1.6, and 1.3, respectively, compared to Star-forming galaxies. We compare our predictions of Sigma_gas with those obtained by inverting the Kennicutt-Schmidt relation and find that our new method is a factor of two more accurate in predicting Sigma_gas, with an average deviation of 32% from the actual Sigma_gas.

description: The main goal of this study was the elucidation of structures of products of oxidation of industrial hydrolysis lignin (HL) obtained in the system H2O2-H2SO4-H2O. It was found that the obtained oxidized hydrolysis lignin (OHL) contained structural fragments of muconic acid dilactone. The latter appeared as a result of the oxidation of aromatic ring of HL into unstable structures of 3,4-dihydroxyadipic acid, which are spontaneously cyclized into the corresponding fragments of muconic acid dilactone in acidic oxidative medium. Consequent reaction of OHL with aqueous sodium hydroxide (NaOH) led to the formation of sodium salt of OHL (Na-OHL), in which the muconic acid dilactone units of OHL opened into fragments of disodium salts of 3,4-dihydroxyadipic acid. The Na-OHL was transformed into the series of novel derivatives of lignins. Thus, the reaction of Na-OHL with thionyl chloride proceeded as a substitution of hydroxyl groups into chlorine atoms in the structure of OHL, that afforded chloro-derivative of OHL. The latter was transformed into amino-amide and ester-ether derivatives of OHL by nucleophilic substitution of chlorine atoms with amines and alcohols correspondingly.

description: Hydroxylamine (NH2OH) is one of the potential precursors of complex pre-biotic species in space. Here we present a detailed experimental study of hydroxylamine formation through nitric oxide (NO) surface hydrogenation for astronomically relevant conditions. The aim of this work is to investigate hydroxylamine formation efficiencies in polar (water-rich) and non-polar (carbon monoxide-rich) interstellar ice analogues. A complex reaction network involving both final (N2O, NH2OH) and intermediate (HNO, NH2O, etc.) products is discussed. The main conclusion is that hydroxylamine formation takes place via a fast and barrierless mechanism and it is found to be even more abundantly formed in a water-rich environment at lower temperatures. In parallel, we experimentally verify the non-formation of hydroxylamine upon UV photolysis of NO ice at cryogenic temperatures as well as the non-detection of NC- and NCO-bond bearing species after UV processing of NO in carbon monoxide-rich ices. Our results are implemented into an astrochemical reaction model, which shows that NH2OH is abundant in the solid phase under dark molecular cloud conditions. Once NH2OH desorbs from the ice grains, it becomes available to form more complex species (e.g., glycine and beta-alanine) in gas phase reaction schemes.

description: We report occurrence of large magnetoresistance in lightly doped antiferromagnetic paraelectric EuTiO3. Reports of magnetoresistance in rare-earth titanates (RTiO3 oxides) are very scarce because they are highly insulating at low temperatures. EuTiO3 is an insulator at 2.5 K and 1% La3+ substitution for Eu2+ lowers the resistivity over five orders of magnitude at 2.5 K. It is shown that Eu0.99La0.01TiO3 which is antiferromagnetic below T= 5.43 K shows large magnetoresistance over a wide temperature. At 2.5 K, magnetoresistance is -42 % for H = 6 kOe and it increases to -75 % for H = 7 T. Even at 50 K which is ten times higher than Neel temperature, magnetoresistance is very significant (-20 % for H = 7 T). It is suggested that 4f spins on Eu2+ ion is strongly exchange coupled to doped electron in Ti-3d band via f-d interation and field-induced suppression of 4f spin fluctuations decrease spin-disorder scattering experienced by 3d electrons. In view of our results, it will be interesting to investigate magnetoresistance of other rare earth titanates.

These solutions have many free parameters such that they may be used to simulate many experimental situations, and to precisely control the dynamics of the system.

Technical Capacity Building and the Growth of an NREN - Case Study: RENU since 2014
Creators: name: Mbonimpa, Nicholas
Publisher: name: My University
Year: 2017

description: An NREN network is an aggregation of member institution networks. Sadly, the state of the member institution networks, and the technical competence of member institution network and systems administrators are, many a time, not considered vital contributors to the growth of an NREN. The member institution technical staff are faced with various hardships in their day to day tasks. Aside from the limited budgets allocated to ICT departments, there are two other major reasons for these hardships; the limited network and systems support skills, and the very poor state of the networks of member institutions - many of which are inherited from several generations of neglect. In this paper, we present the technical capacity building drive that was undertaken in RENU and also seek to bring out the impact it has had on the growth of RENU as an NREN. The background and the problems facing campus networks are brought out in the first chapter of this paper. The second chapter details the activities and structure of the RENU capacity building program. In the third chapter, we discuss the benefits and results (both direct and indirect) that have come out of the capacity building program. A trajectory of RENU’s growth from 2014 as a network and an NREN community is discussed, highlighting the invisible contribution of technical capacity building. The challenges faced are discussed in the chapter before the conclusion. We conclude by arguing that an NREN suffers in various ways when member institution networks function sub optimally. Keywords/phrases: throughput, bandwidth, latency, bottleneck, capacity building, campus networks, direct engineering assistance.

description: Motivation: Meta-analysis methods widely used for combining metabolomics data do not account for correlation between metabolites or missing values. Within- and between-study variability are also often overlooked. These can give results with inferior statistical properties, leading to misidentification of biomarkers. Results: We propose a multivariate meta-analysis model for high-dimensional metabolomics data (MetaHD), which accommodates the correlation between metabolites, within- and between-study variances, and missing values. MetaHD can be used for integrating and collectively analysing individual-level metabolomics data generated from multiple studies as well as for combining summary estimates. We show that MetaHD leads to lower root mean square error compared to the existing approaches. Furthermore, we demonstrate that MetaHD, which exploits the borrowing strength between metabolites, could be particularly useful in the presence of missing data compared with univariate meta-analysis methods, which can return biased estimates in the presence of data missing at random.
Addressing the statistical mechanics of planet orbits in the solar system

description: The chaotic nature of planet dynamics in the solar system suggests the relevance of a statistical approach to planetary orbits. In such a statistical description, the time-dependent position and velocity of the planets are replaced by the probability density function (PDF) of their orbital elements. It is quite natural to set up this kind of approach in the framework of statistical mechanics. In the present paper I focus on the collisionless excitation of eccentricities and inclinations by gravitational interactions in a planetary system, the prototype of such a dynamics being the future planet trajectories in the solar system. I thus address the statistical mechanics of the planetary orbits in the solar system and try to reproduce the PDFs numerically constructed by Laskar (2008). I show that the microcanonical ensemble of the Laplace-Lagrange theory accurately reproduce the statistics of the giant planet orbits. To model the inner planets I then investigate the ansatz of equiprobability in the phase space constrained by the secular integrals of motion. The eccentricity and inclination PDFs of Earth and Venus are reproduced with no free parameters. Within the limitations of a stationary model, the predictions also show a reasonable agreement with Mars PDFs and that of Mercury inclination. The eccentricity of Mercury demands in contrast a deeper analysis. I finally revisit Laskar's random walk approach to the time dependence of the inner planet PDFs. Such a statistical theory could be combined with direct numerical simulations of planet trajectories in the context of planet formation, which is likely to be a chaotic process.

Blockchain technology: Facilitating collaborative research via Intellectual Property sharing
Creators: name: Thabiso, Mpofu
Publisher: name: My University

description: Blockchain is the underlying technology on which CryptoCurrencies such as Bitcoin and Etherium are based. Blockchain is implemented via the use of a distributed ledger. Blockchain ensures permanence of information and addition or modification is subject to everyone and the owner of information contained in the ledger agreeing as well thus making it temper proof. Transactions are grouped into blocks and time stamped and the whole mechanism is decentralised in nature and open to anyone and everyone. Many African countries currently do not have the requisite information sharing infrastructure in place. The use of blockchain technology will enable African and other developing countries to jump the technology gap. The current ledger systems where Intellectual property is adjudicated and stored (such as ARIPO) is centralised in nature. The storage and sharing of Intellectual property such as Patents could harness such technology as blockchain. Various academic, corporate and research institutions across the African continent and other developing countries can be able to share and access Intellectual Property inexpensively and thus effectively facilitating collaborative research.
The NEAAR Collaboration: Supporting low-cost PerfSONAR deployments for end-to-end perfomance monitoring

description: The Networks for European, American, and African Research (NEAAR) collaboration, led by Indiana University and GEANT in partnership with the UbuntuNet Alliance, WACREN, ASREN, SANReN, and TENET, is building a dynamic platform for connecting researchers in the US with their counterparts in Europe and Africa. By providing bandwidth, targeted education and training, and pro-active end-user engagement, NEAAR, funded by the US National Science Foundation, is significantly improving connectivity for existing science collaborations while also enabling new collaborations to take advantage of the growing global research and education networking infrastructure. Since launching in late 2016, the NEAAR project partners have made significant progress towards achieving the project’s year 1 goals. A 100 GB circuit between New York City and London has been installed, adding 100GB of transatlantic connectivity and increased resiliency to the Advanced North Atlantic (ANA) collaboration. The NEAAR partners have also started working to deploy an Open Exchange Point in West Africa that will enable additional peering and resilience for African RENs. Finally, the NEAAR partners have begun working on a human capacity building program that is supporting regional perfSONAR workshops, one-on-one consultations, and other targeted training opportunities for African NRENs and campus staff. This talk will provide updates on these and other NEAAR year 1 developments, an overview of lessons learned to date, and a brief look into what to expect in year 2.
Fine-graind Image Classification via Combining Vision and Language

description: Fine-grained image classification is a challenging task due to the large intra-class variance and small inter-class variance, aiming at recognizing hundreds of sub-categories belonging to the same basic-level category. Most existing fine-grained image classification methods generally learn part detection models to obtain the semantic parts for better classification accuracy. Despite achieving promising results, these methods mainly have two limitations: (1) not all the parts which obtained through the part detection models are beneficial and indispensable for classification, and (2) fine-grained image classification requires more detailed visual descriptions which could not be provided by the part locations or attribute annotations. For addressing the above two limitations, this paper proposes the two-stream model combining vision and language (CVL) for learning latent semantic representations. The vision stream learns deep representations from the original visual information via deep convolutional neural network. The language stream utilizes the natural language descriptions which could point out the discriminative parts or characteristics for each image, and provides a flexible and compact way of encoding the salient visual aspects for distinguishing sub-categories. Since the two streams are complementary, combining the two streams can further achieves better classification accuracy. Comparing with 12 state-of-the-art methods on the widely used CUB-200-2011 dataset for fine-grained image classification, the experimental results demonstrate our CVL approach achieves the best performance.

Collaboration in Academia: Motives, Forms and Impacts on scientific Productivity

description: With the Internet becoming readily available and cheaper, even in the most remote corners of the world, opportunities for exchanges of all kinds are more and more wide spread. This is true for the exchange of ideas, results and research methods. Many scientists are taking advantage of these new opportunities by working collaboratively with peers, industry and governments both locally or in further places. The review of the literature on such activities clearly shows that industry-university collaboration in applied engineering receives the bulk of the attention. As well, these previous studies mainly focus on mechanisms and the financial costs and benefits of collaborative research. They thus leave out the impact of collaboration on academic productivity. Some of these studies also claim that collaborative research is just a pretext for generating additional research funds with minimum coordination. Others further contend that increased collaboration by scientists and educators will ultimately bastardize the traditional mission of universities, i.e. producing graduates and generating new knowledge and ideas. While these previous studies shed useful lights on scientists' collaborative activities, by mainly focusing on applied engineering, they are limited in scope. They also overlook many of the motives behind collaborative activities in academia. These omissions are in addition to the limited attention they pay to the impacts of collaboration on scientists' productivity. Using information from a survey of 1,566 scientists from all scientific disciplines in Québec, Canada, our study tries to overcome some of these limitations by i) looking at collaboration by scientists from all scientific disciplines; ii) by accounting and comparing collaborative activities among 1) researchers; 2) with industry; and 3) with other institutions, namely, governments and organized interest groups and finally iii) by assessing the impacts of these collaborative activities on scientific production. The results show that collaboration is prevalent in all scientific disciplines even though scientists in humanities have fewer collaborative output than others. As well, motives for collaboration are of three types: strategic, organisational and operational. Furthermore, even though academic collaboration intended to produce patented or unpatented products, scientific instruments, softwares and artistic products has few output, collaboration ultimately increases productivity, regardless of the discipline or the partners. Thus, university administrators aided by NRENs, government decision-makers and other donors should work at creating and enabling a collaborative friendly environment for academic researchers.
