description: We characterize waves in small magnetic elements and investigate their propagation in the lower solar atmosphere from observations at high spatial and temporal resolution. We use the wavelet transform to analyze oscillations of both horizontal displacement and intensity in magnetic bright points found in the 300 nm and the Ca II H 396.8 nm passbands of the filter imager on board the Sunrise balloon-borne solar observatory. Phase differences between the oscillations at the two atmospheric layers corresponding to the two passbands reveal upward propagating waves at high frequencies (up to 30 mHz). Weak signatures of standing as well as downward propagating waves are also obtained. Both compressible and incompressible (kink) waves are found in the small-scale magnetic features. The two types of waves have different, though overlapping, period distributions. Two independent estimates give a height difference of approximately 450+-100 km between the two atmospheric layers sampled by the employed spectral bands. This value, together with the determined short travel times of the transverse and longitudinal waves provide us with phase speeds of 29+-2 km/s and 31+-2 km/s, respectively. We speculate that these phase speeds may not reflect the true propagation speeds of the waves. Thus, effects such as the refraction of fast longitudinal waves may contribute to an overestimate of the phase speed.

description: We propose a systematic procedure called the Clebsch canonization for obtaining a canonical Hamiltonian system that is related to a given Lie-Poisson equation via a momentum map. We describe both coordinate and geometric versions of the procedure, the latter apparently for the first time. We also find another momentum map so that the pair of momentum maps constitute a dual pair under a certain condition. The dual pair gives a concrete realization of what is commonly referred to as collectivization of Lie-Poisson systems. It also implies that solving the canonized system by symplectic Runge-Kutta methods yields so-called collective Lie-Poisson integrators that preserve the coadjoint orbits and hence the Casimirs exactly. We give a couple of examples, including the Kida vortex and the heavy top on a movable base with controls, which are Lie-Poisson systems on $\mathfrak{so}(2,1)^{*}$ and $(\mathfrak{se}(3) \ltimes \mathbb{R}^{3})^{*}$, respectively.

description: An essential feature of any successful organization is employees' satisfaction. One of the most important challenges facing managers is therefore the creation of a context within which employee satisfaction is enhanced and sustained. This motivates employees to act effectively enabling the organization to achieve its vision, mission and goals. Therefore, the perception of an employee towards employment has a direct effect on the quality of the expected output. The purpose of this study was to assess the factors that affect employee job satisfaction in project-driven organization: the case of Onesimus Children Development Association (OCDA). More over this research also aims to find out the overall job satisfaction level in OCDA and to show the outcome of job satisfaction on employee performance. The researcher has used stratified sampling technique and sample size determination formula delivered by Yamane. The sample of the study consisted of 140 employees through semi structured questionnaire and of which all questionnaires were returned and processed. The statistical software version 20.0 and excel spread sheet have been used to analyze the generated data. The collected data were analyzed using descriptive and inferential statistics that includes frequencies, percentages, means and standard deviations. Some of the respondents appeared to be satisfied with, and well-motivated by their jobs. In the site of the findings, working environment seems to be one of the most important elements of job satisfaction followed by Training and leadership, Reward, Organizational structure, Organizational culture. The study also shown that the employee's job satisfaction can affect employee's productivity and performance, self-reliance level, actions, connection with coworkers, influence to the group and the excellence of jobs output. So, Onesimus Children Development Association/ OCDA/ needs to create an empowerment culture, gratitude and prizes to the employees for their hard work ,support the working method of the organizations with various technology and system mechanizations, establish employee recognition frame work, Provide training to meet the career needs of employees, formulate a fair promotion system ,and develop the leaders and managers capacity on teaching and mentoring and design or customize HRM practices in order to motivate the employees' and gain competitive advantage by establishing a fair rewarding system and provide equitable and competitive benefit package to the financial sector. And also there should be a constant communication between top management and all employees of the organization.

description: After the discovery of the Higgs boson, understanding the nature of electroweak symmetry breaking and the associated electroweak phase transition has become the most pressing question in particle physics. Answering this question is a priority for experimental studies. Data from the LHC and future lepton collider-based Higgs factories may uncover new physics coupled to the Higgs boson, which can induce the electroweak phase transition to become first order. Such a phase transition generates a stochastic background of gravitational waves, which could potentially be detected by a space-based gravitational wave interferometer. In this paper, we survey a few classes of models in which the electroweak phase transition is strongly first order. We identify the observables that would provide evidence of these models at the LHC and next-generation lepton colliders, and we assess whether the corresponding gravitational wave signal could be detected by eLISA. We find that most of the models with first order electroweak phase transition can be covered by the precise measurements of Higgs couplings at the proposed Higgs factories. We also map out the model space that can be probed with gravitational wave detection by eLISA.

description: Fluid dynamic considerations are used to determine the electric current spectral density in the regime of small energies and momenta. The spectral density in this regime is parameterized by the electric conductivity, the charge susceptibility, and the relaxation time for the electric current, which is needed for relativistic causality. Experimentally, the spectral function can be accessed through the production rates of photons and dileptons in the expanding quark-gluon plasma. We use fluid dynamic simulations of high energy nuclear collisions, together with the transport limit of the spectral density, to obtain photon and dielectron spectra for different values of the conductivity and relaxation times. The yields of photon and dileptons produced in the plasma are compared to the background from decays of short-lived hadrons. We discuss how experiments can constrain the electrical conductivity and associated relaxation time of the quark-gluon plasma.

description: Controlling interactions out of thermodynamic equilibrium is crucial for designing addressable and functional self-organizing structures. These active interactions also underpin collective behavior in biological systems. Here we study a general setting of active particles in a bath of passive particles, and demonstrate a novel mechanism for long range attraction between active particles. The mechanism operates when the translational persistence length of the active particle motion is smaller than the particle diameter. In this limit, the system reduces to particles of higher diffusivity ("hot" particles) in a bath of particles with lower diffusivity ("cold" particles). This attractive interaction arises as a hot particle pushes cold particles away to create a large hole around itself, and the holes interact via a depletion-like attraction. Strikingly, the interaction range is more than an order of magnitude larger than the particle radius, well beyond the range of conventional depletion force. Although the mechanism occurs outside the parameter regime of typical biological swimmers, the mechanism could be realized in the laboratory.

description: Future in situ space plasma investigations will likely involve spatially distributed observatories comprised of multiple spacecraft, beyond the four and five spacecraft configurations currently in operation. Inferring the magnetic field structure across the observatory, and not simply at the observation points, is a necessary step towards characterizing fundamental plasma processes using these unique multi-point, multi-scale data sets. We propose improvements upon the classic first-order reconstruction method, as well as a second-order method, utilizing magnetometer measurements from a realistic nine-spacecraft observatory. The improved first-order method, which averages over select ensembles of four spacecraft, reconstructs the magnetic field associated with simple current sheets and numerical simulations of turbulence accurately over larger volumes compared to second-order methods or first-order methods using a single regular tetrahedron. Using this averaging method on data sets with fewer than nine measurement points, the volume of accurate reconstruction compared to a known magnetic vector field improves approximately linearly with the number of measurement points.

description: The Fisher matrix is a widely used tool to forecast the performance of future experiments and approximate the likelihood of large data sets. Most of the forecasts for cosmological parameters in galaxy clustering studies rely on the Fisher matrix approach for large-scale experiments like DES, Euclid, or SKA. Here we improve upon the standard method by taking into account three effects: the finite window function, the correlation between redshift bins, and the uncertainty on the bin redshift. The first two effects are negligible only in the limit of infinite surveys. The third effect, on the contrary, is negligible for infinitely small bins. Here we show how to take into account these effects and what the impact on forecasts of a Euclid-type experiment will be. The main result of this article is that the windowing and the bin cross-correlation induce a considerable change in the forecasted errors, of the order of 10-30% for most cosmological parameters, while the redshift bin uncertainty can be neglected for bins smaller than $Δz = 0.1$ roughly.

The enhancement consists in allowing morphisms from an object to itself to be chains on the manifold. Higher compositions correspond to counting Morse trees passing through a given set of chains. We provide two viewpoints on the construction and on the proof of the $A_\infty$ relations for the composition maps. One viewpoint is via an effective action for the $BF$ theory computed in a special gauge. The other is via higher topological quantum mechanics.

These theories, unlike their equal level counterparts, possess a new non-trivial fixed point in the IR. By computing the exact in $λ$ two- and three-point functions for these operators we deduce their OPEs and their equal-time commutators. Using these we argue on the nature of the CFT at the IR fixed point. The associated to the currents Poisson brackets are a two-parameter deformation of the canonical structure of the isotropic PCM.

description: Group theoretical methods and ${\bf k}\cdot{\bf p}$ theory are combined to determine spin-dependent contributions to the effective conduction band Hamiltonian. To obtain the constants in the effective Hamiltonian, in general all invariants of the Hamiltonian have to be determined. Hence, we present a systematic approach to keep track of all possible invariants and apply it to the ${\bf k}\cdot{\bf p}$ Hamiltonian of crystals with zinc-blende symmetry, in order to obtain all possible contributions to effective quantities such as effective mass, g-factor and Dresselhaus constant. Further spin-dependent contributions to the effective Hamiltonian arise in the presence of strain. In particular, with regard to the constants $C_3$ and $D$ which describe spin-splitting linear in the components of ${\bf k}$ and ${\boldsymbol\varepsilon}$, considering all possible terms allowed by symmetry is crucial.

description: In the 1980's Colliot-Thélène, Sansuc, Kato and S. Saito proposed conjectures related to local-to-global principles for $0$-cycles on arbitrary smooth projective varieties over a number field. We give some evidence for these conjectures for a product $X=E_1\times E_2$ of two elliptic curves. In the special case when $X=E\times E$ is the self-product of an elliptic curve $E$ over $\mathbb{Q}$ with potential complex multiplication, we show that the places of good ordinary reduction are often involved in a Brauer-Manin obstruction for $0$-cycles over a finite base change. We give many examples when these $0$-cycles can be lifted to global ones.

description: A simple, inexpensive and field applicable metal determination system would be a powerful tool for the efficient control of metal ion contamination in various sources e.g. drinking-water, water reservoir and waste discharges. In this study, we developed a cell-based metal sensor for specific and real-time detection of copper ions. E. coli expressing metal-sensing green fluorescent protein (designated as TG1/(CG)6GFP and TG1/H6CdBP4GFP) were constructed and served as a metal analytical system. Copper ions were found to exert a fluorescence quenching effect, while zinc and cadmium ions caused minor fluorescence enhancement in the engineered bacterial suspension. To construct a user-friendly and reagentless metal detection system, TG1/H6CdBP4GFP and TG1/(CG)6GFP were encapsulated in polyacrylamide hydrogels that were subsequently immobilized on an optical fiber equipped with a fluorescence detection module. The sensor could be applied to measure metal ions by simply dipping the encapsulated bacteria into a metal solution and monitoring fluorescence changes in real time as a function of the metal concentration in solution. The sensor system demonstrated high specificity toward copper ions. The fluorescence intensities of the encapsulated TG1/(CG)6GFP and TG1/H6CdBP4GFP were quenched by approximately 70 % and 80 % by a high-dose of copper ions (50mM), respectively. The level of fluorescence quenching exhibited a direct correlation with the copper concentration, with a linear correlation coefficient (r) of 0.99. The cell-based metal sensor was able to efficiently monitor copper concentrations ranging between 5 µM and 50 mM, encompassing the maximum allowed copper contamination in drinking water (31.15 µM) established by the WHO. Furthermore, the cell-based metal sensor could undergo prolonged storage for at least 2 weeks without significantly influencing the copper sensitivity.

description: Acute diseases are characterised by a rapid onset of symptoms resulting in the need for intensive care. Globally ~20 million people per year are diagnosed with an acute disease and of these 30% die. Death results from a progression to organ failure that currently has no specific treatments. Recent findings show that gut-lymph serves as a conduit for toxins to enter the blood where the toxins damage organs. This thesis contains the first steps toward the application of neutralizing these toxins by lymphatic drug delivery strategies and presents evidence that this approach provides effective treatment of an acute disease.

description: The theory of free Majorana-Weyl spinors is the prototype of conformal field theory in two dimensions in which the gravitational anomaly and the Weyl anomaly obstruct extending the flat spacetime results to curved backgrounds. In this paper, we investigate a quantization scheme in which the short distance singularity in the two-point function of chiral fermions on a two dimensional curved spacetime is given by the Green's function corresponding to the classical field equation. We compute the singular term in the Green's function explicitly and observe that the short distance limit is not well-defined in general. We identify constraints on the geometry which are necessary to resolve this problem. On such special backgrounds the theory has locally $c=\frac{1}{2}$ conformal symmetry.

description: The current study determined the prevalence of chronic kidney disease associated pruritus (CKD-aP) and its impact on wellbeing and sleep quality among hemodialysis patients. Furthermore we aimed to quantify the effect of zolpidem versus acupressure in improving the sleep quality. The prevalence of CKD-aP was observed to be 74% in Pakistan and 61.3% in Malaysia. Pakistani patients had poorer quality of life score compared to Malaysian patients (52.0% vs 55.0%). A longer duration of CKD, older age and a higher pruritus score were associated with poor sleep quality. Zolpidem (10mg) was observed to have significant improvement in sleep quality of patients suffering from CKD-aP.

description: In this work, FeSe2@CNT nanocomposite anode materials are fabricated using a convenient and efficient one-step microwave method. The FeSe2@CNT electrode exhibits superior electrochemical performance. The carbon nanotube structure effectively mitigates the severe volume change in the FeSe2@CNT electrode during continuous charge and discharge. Thus, the capacitance value of 573 F g−1 and capacitance retention of 81.9% for 3000 constant current charge and discharge cycles are achieved. In addition, the asymmetric device assembled with FeSe2@CNT as the anode and NiSe2@CNT as the cathode exhibits high Energy density (E can reach 41.32 Wh kg−1 when P is 800 W kg−1), and the device achieves 82.6% capacity retention after 3000 cycles.

description: The main objective of this research paper is to identify the critical success factors in the building construction projects at Bole Arabsa and Bole Bulbula condominium sites. In addition, one of the objectives is to see the understanding of the project executioners towards the project management body of knowledge areas. The significance of this study is identification of success factors, huge contribution to knowledge development and serves as a reference for other researchers. On the way, the study examined the critical factors that ensure the success of a project using frequency percentage and Relative index approach. Construction industry is the backbone for the economy and the successful completion of projects plays a vital role for development. Thus, it is important to identify the factors which lead a project to be success and it is the main reason for the study to be conducted. The paper is descriptive type and the method used to gather data from the sites is questionnaire and reviewed the related literatures to organize the factors. The study used both primary and secondary data sources. The targeted population for the study was taken from governmental and privet institutes and only consists the skilled manpower. Due to the size of the targeted population is small, for this study the total targeted population is equal to sample size. The research paper analysis data using percentage frequency and Relative importance index methods. The study indicated 18 general success factors of which the top five average rank scores of the two sites are clear goal, adequate Budget, detail plan, project manager capability, and commitment of project team important to complete a project successfully. The study also indicates that there is a difference between the respondents on ranking the success factors between the two sites. The respondents at Bole Arabsa ranked Clear and defined Goal, detailed plan, support of project consultant, commitment of project team and top management support as top five success factors. While, the respondents at Bole Bulbula ranked Adequate Budget, project manager capability, clear and defined goal, detailed plan and commitment of project team as top five success factors chronologically. The respondents agreed that the 10 knowledge area success factors were important for successful completion of a project even if the differ on ranking of the success factors

description: We study the geometry of the Thurston metric on the Teichmüller space $\mathcal{T}(S)$ of hyperbolic structures on a surface $S$. Some of our results on the coarse geometry of this metric apply to arbitrary surfaces $S$ of finite type; however, we focus particular attention on the case where the surface is a once-punctured torus, $S_{1,1}$. In that case, our results provide a detailed picture of the infinitesimal, local, and global behavior of the geodesics of the Thurston metric, as well as an analogue of Royden's theorem.

description: In parasites, anthelmintic resistance is a major concern globally. There is a high demand for new anthelmintics with new chemical entities and mode of action to circumvent this problem. Parasitic helminths (worms) can be targeted with small-molecule drugs, either directly, or via the attack on bacterial endosymbionts of the genus Wolbachia present in some species. This thesis focuses on the development of lead drug-like molecules with potent anthelmintic activity.

description: We consider the compressible Vlasov-Poisson-Fokker-Planck-Navier-Stokes system in a three dimensional bounded domain with nonhomogeneous Dirichlet boundary conditions. The system describes the evolution of charged particles ensemble dispersed in an isentropic fluid. For the adiabatic coefficient $γ>3/2$, we establish the global existence of weak solutions to this system with arbitrary large initial and boundary data.
