WIND TURBINES

description: Vertical axis wind turbines (VAWTs) have been attracting increasing attention in recent years in order to save fossil resources and protect the environment. However, the relatively low efficiency of VAWTs has limited their development. This paper studies the influence of the airfoil\'s maximum camber as well as its position on the performance of the VAWT based on the CFD analysis. During this process, the Kriging model is applied to the samples accessed by the Latin Hypercube Sampling approach. The influence of the airfoil\'s thickness is studied based on the two-dimensional symmetrical NACA 4 digital airfoils. In addition, the three-dimensional rotating process of the VAWT is studied by simulating a single blade with the assistant of a UDF file. Based on this approach, this paper investigates the 3D blade\'s shape on its aerodynamic performance and power coefficient. The current result shows that the straight blade with a symmetrical airfoil has the best power efficiency. The thickness of the NACA0018 is the most suitable for the operating conditions investigated.

description: The CFVib experiment investigated the use of piezoelectric actuators to manipulate fluids via the vibroequilibria effect. A model is developed to simulate fluid behaviour in this experiment, including interaction with the container and piezoelectrics. Since vibroequilibria evolve slowly compared to the applied forcing, a separation of timescales is used to obtain a linear problem on the fast timescale whose solution provides a quasisteady source term driving slow vibroequilibria dynamics. We find that the surface adopts different vibroequilibria depending on the selected mode of vibration. Simulations show good agreement with experiments and suggest a potential strategy for manipulating fluids in weightlessness.
Material-specific gap function in the high-temperature superconductors

description: We present theoretical arguments and experimental support for the idea that high-Tc superconductivity can occur with s-wave, d-wave, or mixed-wave pairing in the context of a magnetic mechanism. The size and shape of the gap is different for different materials. The theoretical arguments are based on the t-J model as derived from the Hubbard model so that it necessarily includes three-site terms. We argue that this should be the basic minimal model for high-Tc systems. We analyze this model starting with the dilute limit which can be solved exactly, passing then to the Cooper problem which is numerically tractable, then ending with a mean field approach. It is found that the relative stability of s-wave and d-wave depends on the size and the shape of the Fermi surface. We identify three striking trends. First, materials with large next-nearest-neighbor hopping (such as YBa(2)Cu(3)O(7-x)) are nearly pure d-wave, whereas nearest-neighbor materials (such as La(2-x)Sr(x)CuO(4)) tend to be more s-wave-like. Second, low hole doping materials tend to be pure d-wave, but high hole doping leads to s-wave. Finally, the optimum hole doping level increases as the next-nearest-neighbor hopping increases. We examine the experimental evidence and find support for this idea that gap function in the high-temperature superconductors is material-specific.

description: ClJ1449+0856, a galaxy cluster at z=2, is an exemplary case to investigate everything from galaxy evolution in dense environments, to early-time energetic feedback in clusters, and the physics of the high-redshift intra-cluster medium (ICM). Despite its early epoch, ClJ1449 has now been detected in both diffuse X-ray emission and through the thermal Sunyaev Zel’Dovich effect - the lowest mass single SZ detection to date, confirming its virialised nature. In this talk, I will summarise the picture of high-redshift galaxy and cluster evolution emerging from ClJ1449 so far, and present our latest discoveries. Having uncovered a population of highly-excited, merging, star-forming galaxies in ClJ1449, we turn our attention to the excess radio emission at 3GHz. We discover multiple faint radio-jet emission sites in the cluster core - quite unlike the picture in local galaxy clusters, where Active Galactic Nuclei (AGN) activity is confined to a single central galaxy. I will discuss the implications of this kinetic feedback for energy injection into the ICM, gas accretion, and the infrared-radio correlation in dense environments. Finally, I introduce our future goal to quantify the cold ICM in ClJ1449.

In this paper, the kinematics model of fo ldable Flapping Wing Aircraft is constructed with reference to bats. The aerodynamic modeling method is a co mbination of the quasiconstant model and the elemental theory with wash effect. The longitudinal dynamics model is constructed through multi-rig id body finite element method. Robust variable gain control method is used to analyze the closed-loop longitudinal stability of foldable Flapping Wing Aircraft.

description: Based on a broad evaluation of possible Semi-RLV configurations with a vertical take-off, vertical landing (VTVL) first stage, a two staged concept with a methane fueled first stage and hydrogen fueled second stage was selected for further investigation. A number of parameter studies were undertaken to identify optimal design trends specific to VTVL-stages. These parametric studies and their results are the core of this paper. Based on the results a robust initial design was developed and will in further steps be investigated on a subsystem level in order to promote the understanding of reuse-related technologies within Europe.

description: Let $X$ be a compact connected Riemann surface, $D\, \subset\, X$ a reduced effective divisor, $G$ a connected complex reductive affine algebraic group and $H_x\, \subsetneq\, G_x$ a Zariski closed subgroup for every $x\, \in\, D$. A framed principal $G$--bundle is a pair $(E_G,\, ϕ)$, where $E_G$ is a holomorphic principal $G$--bundle on $X$ and $ϕ$ assigns to each $x\, \in\, D$ a point of the quotient space $(E_G)_x/H_x$. A framed $G$--Higgs bundle is a framed principal $G$--bundle $(E_G,\, ϕ)$ together with a section $θ\, \in\, H^0(X,\, \text{ad}(E_G)\otimes K_X\otimes{\mathcal O}_X(D))$ such that $θ(x)$ is compatible with the framing $ϕ$ for every $x\, \in\, D$. We construct a holomorphic symplectic structure on the moduli space $\mathcal{M}_{FH}(G)$ of stable framed $G$--Higgs bundles. Moreover, we prove that the natural morphism from $\mathcal{M}_{FH}(G)$ to the moduli space $\mathcal{M}_{H}(G)$ of $D$-twisted $G$--Higgs bundles $(E_G,\, θ)$ that forgets the framing, is Poisson. These results generalize \cite{BLP} where $(G,\, \{H_x\}_{x\in D})$ is taken to be $(\text{GL}(r,{\mathbb C}),\, \{\text{I}_{r\times r}\}_{x\in D})$. We also investigate the Hitchin system for $\mathcal{M}_{FH}(G)$ and its relationship with that for $\mathcal{M}_{H}(G)$.

description: Abstract
Literature shows more of the world population turns to coffee consumption particularly Latin America, India and China. Demand for the beverage is estimated to increase by nearly 25% over the coming five years. On the other hand, global coffee production and supply is very unlikely to increase due to many factors. To fill the expected gap between production and consumption, Ethiopia has a better opportunity. Current productivity per hectare is about 647 kg which is lower than in many growing countries. Eventually, the research developed 42 coffee verities among which 35 are selections and seven of them are hybrids. As different coffee husbandry technologies enable to boost coffee production and productivity many agronomic practices are generated and recommended along with coffee varieties.

description: We calculate the number spectrum of particles radiated during a scattering into a heat bath using the thermal largest-time equation and the Dyson-Schwinger equation. We show how one can systematically calculate {d}/{dω} to any order using modified real time finite-temperature diagrams. Our approach is demonstrated on a simple model where two scalar particles scatter, within a photon-electron heat bath, into a pair of charged particles and it is shown how to calculate the resulting changes in the number spectra of the photons and electrons.

description: We discuss the production of $t\bar t$ quark-antiquark pairs in proton-proton collisions via the $γγ$ fusion mechanism. We include topologies in which both protons stay intact or one or even both of them undergo dissociation. The calculations are performed within the $k_{\rm T}$-factorisation approach, including transverse momenta of intermediate photons. Photon fluxes associated to inelastic (dissociative) processes are calculated based on modern parameterisations of proton structure functions. We find an integrated cross section of about 2.36 fb at $\sqrt{s}=$ 13 TeV for all contributions. The cross section for the fully elastic process is the smallest. Inelastic contributions are significantly reduced when a veto on outgoing jets is imposed. We present several differential distributions in rapidity and transverse momenta of single $t$ or $\bar t$ quarks/antiquarks as well as distributions in invariant mass of both the $t\bar t$ and masses of dissociated systems. A few two-dimensional distributions are presented in addition.

AGN feedback in the Planck selected Clusters: a detailed study of X-ray cavities
Creators: name: Olivares, Valeria

Publisher: name: Zenodo
Year: 2021

description: We present a statistical study of X-ray cavities in 77 CC and 112 NCC Planck selected clusters using Chandra observations to further insight into how AGN feedback operates on clusters. The Planck cluster sample is an all-sky mass-selected, nearly unbiased sample of galaxy clusters at moderate redshift (z<0.5), which could reflect the entire AGN feedback cycle at the centers of galaxy clusters. We find that the AGN heating traced by the power of the X-ray cavities alone is able to balance the radiative losses of the ICM in our sample. Our observations show a hint on how the dynamical state of the clusters could affect the asymmetries of the cavities. We also found that clusters with cavities also display Halpha emission, indicating the important role of AGN feedback on the condensation of gas in CC clusters. However, a few Halpha emitting systems lack X-ray cavities, suggesting either different heating mechanisms or different timescales for the dissipation of the X-ray cavities and the cold gas.

description: Transport and mixing processes in fluid flows can be studied directly from Lagrangian trajectory data, such as obtained from particle tracking experiments. Recent work in this context highlights the application of graph-based approaches, where trajectories serve as nodes and some similarity or distance measure between them is employed to build a (possibly weighted) network, which is then analyzed using spectral methods. Here, we consider the simplest case of an unweighted, undirected network and analytically relate local network measures such as node degree or clustering coefficient to flow structures. In particular, we use these local measures to divide the family of trajectories into groups of similar dynamical behavior via manifold learning methods.

description: Glioblastoma and neuroblastoma are malignant tumors of the brain and central nervous system. Current treatment options are limited to treating these malignancies. There is a need to find new adjuvants to combat these cancers. Natural products and their derivatives are promising anticancer agents because of their broad pharmacological activities. Curcumin has shown remarkable anticancer effects against various cancers by targeting many molecular targets in cancer development. Curcumin analogs such as diarylpentanoids (e.g., MS17) are emerging anticancer agents. MS17 has shown potent cell growth inhibitory effects in in-vitro studies.

description: The bulk composition of the Earth is dramatically carbon poor compared to that of the interstellar medium, and this phenomenon extends to the asteroid belt. To interpret this carbon deficit problem, the carbonaceous component in grains must have been converted into the gas-phase in the inner regions of protoplanetary disks prior to planetary formation. We examine the effect of carbon grain destruction on the chemical structure of disks by calculating the molecular abundances and distributions using a comprehensive chemical reaction network. When carbon grains are destroyed and the elemental abundance of the gas becomes carbon-rich, the abundances of carbon-bearing molecules, such as HCN and carbon-chain molecules, increase dramatically near the midplane, while oxygen-bearing molecules, such as H$_2$O and CO$_2$, are depleted. We compare the results of these model calculations with the solid carbon fraction in the solar system. Although we find a carbon depletion gradient, there are some quantitative discrepancies: the model shows a higher value at the position of asteroid belt and a lower value at the location of the Earth. In addition, using the obtained molecular abundances distributions, coupled with line radiative transfer calculations, we make predictions for ALMA to potentially observe the effect of carbon grain destruction in nearby protoplanetary disks. The results indicate that HCN, H$^{13}$CN and c-C$_3$H$_2$ may be good tracers.

description: We develop a scale-invariant truncated Lévy (STL) process to describe physical systems characterized by correlated stochastic variables. The STL process exhibits Lévy stability for the probability density, and hence shows scaling properties (as observed in empirical data); it has the advantage that all moments are finite (and so accounts for the empirical scaling of the moments). To test the potential utility of the STL process, we analyze financial data.

description: The Read-Rezayi (RR) parafermion states form a series of exotic non-Abelian fractional quantum Hall (FQH) states at filling $ν= k/(k+2)$. Computationally, the wave functions of these states are prohibitively expensive to generate for large systems. We introduce a series of parton states, denoted "$\bar{2}^{k}1^{k+1}$," and show that they lie in the same universality classes as the particle-hole-conjugate RR ("anti-RR") states. Our analytical results imply that a $(U(1)_{k+1} \times U(2k)_{-1})/(SU(k)_{-2} \times U(1)_{-1})$ coset conformal field theory describes the edge excitations of the $\bar{2}^{k}1^{k+1}$ state, suggesting non-trivial dualities with respect to previously known descriptions. The parton construction allows wave functions in anti-RR phases to be generated for hundreds of particles. We further propose the parton sequence "$\bar{n}\bar{2}^{2}1^{4}$," with $n=1,2,3$, to describe the FQH states observed at $ν=2+1/2,~2+2/5$ and $2+3/8$.

description: For two prototype systems, we calculate the exact exchange-correlation kernels $f_{\mathrm{xc}}(x,x',ω)$ of time-dependent density functional theory. $f_{\mathrm{xc}}$, the key quantity for optical absorption spectra of electronic systems, is normally subject to uncontrolled approximation. We find that, up to the first excitation energy, the exact $f_{\mathrm{xc}}$ has weak frequency-dependence and a simple, though non-local, spatial form. For higher excitations, the spatial behavior and frequency-dependence become more complex. The accuracy of the underlying exchange-correlation potential is of crucial importance.

Gas mass calibration in a z=2.5 protocluster
Creators: name: Lee, Minju
Publisher: name: Zenodo
Year: 2021

description: The evolution of cosmic gas content up to z=6 in general fields is now relatively well constrained, thanks to deep and/or wide surveys of dust and CO measurements. Compared to this, the gas measurements of rarer fields including high-z clusters and their progenitors, protoclusters, still suffer from not only the small number of statistics but also the unknown gas mass calibration of, especially more abundant, main-sequence galaxies. Probing these dense environments is important because they offer a unique window in understanding the formation of the earliest quenched population in the early universe. This talk discusses the gas-mass cross-calibration of star-forming main-sequence galaxies in a z=2.5 protocluster, using three different cold gas tracers of dust, CO(3-2), and the lowest atomic carbon transition [C I]^3P_1 −^3P_0 from Atacama Large Millimeter/submillimeter Array observations. The [CI]-based gas measurements are, in general, bridging the gap between the CO(3-2)-based and dust-based measurements. There is a hint that CO-based gas content could be overestimated if one takes the same recipe adopted in the field galaxies. Based on the gas-mass cross calibrations, we find that the mean gas fraction of protocluster galaxies is comparable to field galaxies for a stellar-mass range of log(Mstar/Msun) = [10.6, 11.3]. However, a stronger stellar-mass dependence in the gas depletion time scale is observed and this might be related to earlier quenching in dense environments.
Beam-Induced Nuclear Depolarisation in a Gaseous Polarised Hydrogen Target

description: Spin-polarised atomic hydrogen is used as a gaseous polarised proton target in high energy and nuclear physics experiments operating with internal beams in storage rings. When such beams are intense and bunched, this type of target can be depolarised by a resonant interaction with the transient magnetic field generated by the beam bunches. This effect has been studied with the HERA positron beam in the HERMES experiment at DESY. Resonances have been observed and a simple analytic model has been used to explain their shape and position. Operating conditions for the experiment have been found where there is no significant target depolarisation due to this effect.

description: We study the propagation of very large amplitude localized excitations in a model of DNA that takes explicitly into account the helicoidal structure. These excitations represent the ``transcription bubble'', where the hydrogen bonds between complementary bases are disrupted, allowing access to the genetic code. We propose these kind of excitations in alternative to kinks and breathers. The model has been introduced by Barbi et al. [Phys. Lett. A 253, 358 (1999)], and up to now it has been used to study on the one hand low amplitude breather solutions, and on the other hand the DNA melting transition. We extend the model to include the case of heterogeneous chains, in order to get closer to a description of real DNA; in fact, the Morse potential representing the interaction between complementary bases has two possible depths, one for A-T and one for G-C base pairs. We first compute the equilibrium configurations of a chain with a degree of uncoiling, and we find that a static bubble is among them; then we show, by molecular dynamics simulations, that these bubbles, once generated, can move along the chain. We find that also in the most unfavourable case, that of a heterogeneous DNA in the presence of thermal noise, the excitation can travel for well more 1000 base pairs.

description: We show that the cosmological abundance of string axions is much smaller than naive estimates if the Hubble scale of inflation, $H_{\rm inf}$, is sufficiently low (but can still be much higher than the axion masses) and if the inflation lasts sufficiently long. The reason is that the initial misalignment angles of the string axions follow the Bunch-Davies distribution peaked at the potential minima. As a result, the cosmological moduli problem induced by the string axions can be significantly relaxed by low-scale inflation, and astrophysical and cosmological bounds are satisfied over a wide range of the mass without any fine-tuning of the initial misalignment angles. Specifically, the axion with its decay constant $f_ϕ= 10^{16}$\,GeV satisfies the bounds over $10^{-18}{\rm \, eV} \lesssim m_ϕ\lesssim 10{\rm\,TeV}$ for $H_{\rm inf} \lesssim 10{\rm\,keV}- 10^{6}$\,{\rm GeV}. We also discuss cases with multiple axions and the QCD axion.

description: Based on 25 case studies from the global comparative study ‘GENNOVATE: Enabling gender equality in agricultural and environmental innovation’, this paper explores rural young women’s and men’s occupational aspirations and trajectories in India, Mali, Malawi, Morocco, Mexico, Nigeria, and the Philippines. We draw upon qualitative data from 50 sex-segregated focus groups with the youth to show that across the study’s regional contexts, young rural women and men predominantly aspire for formal blue and white-collar jobs. Yet, they experience an aspirationachievement gap, as the promise of their education for securing the formal employment they seek is unfulfilled, and they continue to farm in their family’s production. Whereas some young men aspired to engage in knowledge-intensive or ‘modern’ agriculture, young women did not express any such interest. Framing our analysis within a relational approach, we contend that various gender norms that discriminate against women in agriculture dissuade young women from aspiring for agriculture-related occupation. We discuss the gendered opportunity spaces of the study sites, the meanings these hold for allowing young women and men to achieve their aspirations and catalyze agricultural innovation, and implications for agricultural policies and research for development. Our findings show that youth and gender issues are inextricably intertwined and cannot be understood in isolation one from the other.

description: ABSTRACT
Prevalent occurrence of P deficiency in strongly acid soils is one of the major problems limiting crop production in high rainfall regions of Ethiopia where Phosphorus (P) fixation, nutrient leaching and soils erosion are common. This work investigated effect of liming and applied mineral P on the P transformation of acid soils of West Wollega, Ethiopia. To study the P transformations, P fractionation was carried out to determine distributions of P in the various P pools. The soils were categorized as strongly acidic in which the pH (H2O) values varied between 4.35 and 4.82.

description: Building on our recent proposal to explain the experimental hints of new physics in $B$ meson decays within the framework of Pati-Salam quark-lepton unification, through the interactions of the $(3,1)_{2/3}$ vector leptoquark, we construct a realistic model of this type based on the gauge group ${\rm SU}(4)_L \times {\rm SU}(4)_R \times {\rm SU}(2)_L \times {\rm U}(1)'$ and consistent with all experimental constraints. The key feature of the model is that ${\rm SU}(4)_R$ is broken at a high scale, which suppresses right-handed lepton flavor changing currents at the low scale and evades the stringent bounds from searches for lepton flavor violation. The mass of the leptoquark can be as low as $10 \ {\rm TeV}$ without the need to introduce mixing of quarks or leptons with new vector-like fermions. We provide a comprehensive list of model-independent bounds from low energy processes on the couplings in the effective Hamiltonian that arises from generic leptoquark interactions, and then apply these to the model presented here. We discuss various meson decay channels that can be used to probe the model and we investigate the prospects for discovering the new gauge boson at future colliders.

Star Formation and Chemical Enrichment in Protoclusters

Year: 2021

description: We study the protocluster’s (PC's) star formation and gas metallicity evolution at \(z=0.6-10\) using the cosmological SPH simulation code GADGET3-Osaka. The total star formation rate in the PC reaches \(3000\ \mathrm{M}_\odot \mathrm{yr}^{-1}\) at \(z=3\), with the core region accounting for about half of the star formation in the PC at \(z\sim2\). For the chemical abundance evolution, we find that the effect of Type II supernova (SN) appears at \(z>3\), while that of Type Ia SN appear at \(z\sim3\) in the core. We also compare the chemical abundance of the gas in individual PC galaxies with observations.

description: Self-pressurizing tank dynamics is modeled using a Baer-Nunziato type multiphase model, with relaxation source terms that account for the exchange of momentum, energy and matter among the phases. Numerical results for nitrous oxide are compared to experimental results available in literature. Since the source terms have an infinite relaxation speed, local thermodynamic equilibrium is reached and the model cannot reproduce the initial pressure and temperature drop observed in experimental results. However it well approximates the subsequent linear decrease of pressure with respect to time. Future work will investigate the effects of finite relaxation speed of the source terms.

description: We present density-matrix renormalization group results for the ground state properties of two-leg Hubbard ladders. The half-filled Hubbard ladder is an insulating spin-gapped system, exhibiting a crossover from a spin-liquid to a band-insulator as a function of the interchain hopping matrix element. When the system is doped, there is a parameter range in which the spin gap remains. In this phase, the doped holes form singlet pairs and the pair-field and the "$4 k_F$" density correlations associated with pair density fluctuations decay as power laws, while the "$2 k_F$" charge density wave correlations decay exponentially. We discuss the behavior of the exponents of the pairing and density correlations within this spin gapped phase. Additional one-band Luttinger liquid phases which occur in the large interband hopping regime are also discussed.

description: Self-disintegration concept is an innovation idea to enhance the regression rate of hybrid propulsion fuels. The self-disintegration fuel consists of fuel particles and functional locking binder. When the binder is unlocked in structure of charge at a critical condition, the fuel charge will be disintegrated into small particles to enlarge the fuel surface. The binder is an important component, and HTPB is convenient binder, but its molecular bond in chain is strong. The functional binders of weaken bond HTPB was designed and processed. The performance of weaken bond HTPB fuels were analyzed in experiments. The experimental results shown that the self-disintegrated effects of weaken bond HTPB induce the increase of regression rates.
