description: Voice over Internet Protocol (VoIP) is a technology that allows you to make voice calls using a broadband Internet connection instead of a regular (or analog) phone line. Voice over Internet Protocol (VoIP) has led human speech to a new level, where conversation across continents can be much cheaper & faster. However, as IP networks are not designed for real-time applications, the network impairments such as packet loss, jitter and delay have a severe impact on speech quality. The playout buffer at the receiver side is used to compensate jitter at a trade-off of delay and loss. We found the characteristics of delay and loss are dependent on IP network and sudden variable delay (spike) often performs both regular and irregular characteristics. Different playout buffer algorithms can have different impacts on the achievement speech quality. It is important to design a playout buffer algorithm which can help achieve an optimum speech quality. In this paper, we investigate to the understanding how network impairments and existing adaptive buffer algorithms affect the speech quality and further to design a modified buffer algorithm to obtain an optimized voice quality. We conduct experiments to existing algorithms and compared their performance under different network conditions with high and low network delay variations. Preliminary results show that the new algorithm can enhance the perceived speech quality in most network conditions and it is more efficient and suitable for real buffer mechanism.

description: A typical formula of multiple zeta values is the sum formula which expresses a Riemann zeta value as a sum of all multiple zeta values of fixed weight and depth. Recently weighted sum formulas, which are weighted analogues of the sum formula, have been studied by many people. In this paper, we give two formulas of weighted sums with two parameters of multiple zeta values. As applications of the formulas, we find some linear combinations of multiple zeta values which can be expressed as polynomials of usual zeta values with coeffcients in the rational polynomial ring generated by the two parameters, and obtain some identities for weighted sums of multiple zeta values of small depths.

description: Teleparallel gravity is an equivalent formulation of general relativity in which instead of the Ricci scalar $R$, one uses the torsion scalar $T$ for the Lagrangian density. Recently teleparallel dark energy has been proposed by Geng et al. in (Geng et al., 2011). They have added quintessence scalar field, allowing also a non-minimal coupling with gravity in the Lagrangian of teleparallel gravity and found that such a non-minimally coupled quintessence theory has a richer structure than the same one in the frame work of general relativity. In the present work we are interested in tachyonic teleparallel dark energy in which scalar field is responsible for dark energy in the frame work of torsion gravity. We find that such a non-minimally coupled tachyon gravity can realize the crossing of the phantom divide line for the effective equation of state. Using the numerical calculations we display such a behavior of the model explicitly.

Two-time scale subordination in physical processes with long-term memory

description: We use the two-time scale subordination in order to describe dynamical processes in continuous media with a long-term memory. Our consideration touches two physical examples in detail. First we study a temporal evolution of the species concentration for the trapping reaction in which a diffusing reactant is surrounded by a sea of randomly moving traps. The analysis is based on the random-variable formalism of anomalous diffusive processes. We find that the empirical trapping-reaction law, according to which the reactant concentration decreases in time as a product of an exponential and a stretched exponential function, can be explained by the two-time scale subordination of random processes. Another example is connected with a state equation for continuous media with memory. If the pressure and the density of a medium are subordinated in two different random processes, then the ordinary state equation becomes fractional with two time scales. This allows one to arrive at the state equation of Bagley-Torvik type.

description: We report an interesting phenomenon of noise-induced vortex reversal in a two-dimensional system of self-propelled particles (SPP) with soft-core interactions. With the aid of forward flux sampling, we analyze the configurations along the reversal pathway and thus identify the mechanism of vortex reversal. We find that statistically the reversal exhibits a hierarchical process: those particles at the periphery first change their motion directions, and then more inner layers of particles reverse later on. Furthermore, we calculate the dependence of the average reversal rate on noise intensity $D$ and the number $N$ of SPP. We find that the rate decreases exponentially with the reciprocal of $D$. Interestingly, the rate varies nonmonotonically with $N$ and a minimal rate exists for an intermediate value of $N$.

description: We performed magnetization M(H,T) and magnetoresistance R(T,H) measurements on powdered (grain size ~ 149 micrometers) as well as highly oriented rhombohedral (A7) bismuth (Bi) samples consisting of single crystalline blocks of size ~ 1x1 mm2 in the plane perpendicular to the trigonal c-axis. The obtained results revealed the occurrence of (1) local superconductivity in powdered samples with Tc(0) = 8.75 \pm 0.05 K, and (2) global superconductivity at Tc(0) = 7.3 \pm 0.1 K in polycrystalline Bi triggered by low-resistance Ohmic contacts with silver (Ag) normal metal. The results provide evidence that the superconductivity in Bi is localized in a tiny volume fraction, probably at intergrain or Ag/Bi interfaces. On the other hand, the occurrence of global superconductivity observed for polycrystalline Bi can be accounted for by enhancement of the superconducting order parameter phase stiffness induced by the normal metal contacts, the scenario proposed in the context of "pseudogap regime" in cuprates [E. Berg et al., PRB 78, 094509 (2008)].

THE EFFECT OF PACKAGING ON CONSUMERS PURCHASE DECISION IN ADDIS ABABA, THE CASE OF YAMI MANGO JUICE
Creators: name: SHEREMEKA SHEBETA
Publisher: name: Zenodo
Year: 2018

description: Due to increasing self-service and changing consumers’ lifestyle the interest in packaging as a tool of sales promotion and stimulator of impulsive buying decision is growing increasingly. So packaging performs an important role in marketing communications, especially in the point of sale and could be treated as one of the most important factors influencing consumer’s purchase decision. Many consumers today shop under higher levels of perceived time pressure and tend to purchase fewer products than intended (Herrington and Capella, 1995; Silayoi and Speece, 2004). Products purchased during shopping excursions often appear to be chosen without prior planning and represent an impulse buying event (Hausman, 2000). A package that attracts consumers at the point of sale will help them make decisions quickly in-store. As the customer’s eye movement tracks across a display of packages, different new packages can be noticed against the competitors. Hence, the research findings could provide how important the packaging elements are to consumers to make decisions at the point of purchase & to marketers how they attract consumers at the point of sale

description: Robbins' problem of optimal stopping asks one to minimise the expected {\it rank} of observation chosen by some nonanticipating stopping rule. We settle a conjecture regarding the {\it value} of the stopped variable under the rule optimal in the sense of the rank, by embedding the problem in a much more general context of selection problems with the nonanticipation constraint lifted, and with the payoff growing like a power function of the rank.

description: We consider the problem of distributed online learning with multiple players in multi-armed bandits (MAB) models. Each player can pick among multiple arms. When a player picks an arm, it gets a reward. We consider both i.i.d. reward model and Markovian reward model. In the i.i.d. model each arm is modelled as an i.i.d. process with an unknown distribution with an unknown mean. In the Markovian model, each arm is modelled as a finite, irreducible, aperiodic and reversible Markov chain with an unknown probability transition matrix and stationary distribution. The arms give different rewards to different players. If two players pick the same arm, there is a "collision", and neither of them get any reward. There is no dedicated control channel for coordination or communication among the players. Any other communication between the users is costly and will add to the regret. We propose an online index-based distributed learning policy called ${\tt dUCB_4}$ algorithm that trades off \textit{exploration v. exploitation} in the right way, and achieves expected regret that grows at most as near-$O(\log^2 T)$. The motivation comes from opportunistic spectrum access by multiple secondary users in cognitive radio networks wherein they must pick among various wireless channels that look different to different users. This is the first distributed learning algorithm for multi-player MABs to the best of our knowledge.

The combined first order spin-density wave/structural transition occurs in the parent CaFe2As2 compound at 168 K and gradually shifts to lower temperature for low doping levels (x = 0.032 and x = 0.051). It is completely suppressed upon higher doping x = 0.056. Simultaneously, superconductivity appears at lower temperature with a transition temperature around Tc = 14.1 K for Ca(Fe0.937Co0.063)2As2. The phase diagram of Ca(Fe0.937Co0.063)2As2 has been derived and the upper critical field is found to be H(c) c2 = 11.5

description: This report contains human-caused injury and mortality records of pinnipeds and cetaceans that occur in U.S. west coast waters for the period 2010-2014, for those species evaluated in Pacific region marine mammal stock assessment reports (SARs) (Carretta et al. 2015a). Mortality records, while included in this report, were obviously not evaluated for SI/NSI status. Subsistence and directed takes (i.e., gray whales taken by Russian natives) are not reported here but are reported in SARs published by NMFS. Previous records, including cases from 2007 through 2009, are published in previous reports (Carretta et al. 2013a, 2014, 2015b). Sources of injury data include strandings, disentanglement networks, the public, researchers, and fishery observer programs. Stranding data includes records of injured marine mammals at sea and ashore. Injury sources include, but are not limited to, vessel strikes, gillnet entanglement, pot and trap gear entanglement, shootings, marine debris entanglement, researchrelated injuries/deaths, hook and line fishery interactions, and power plant water intake entrainment. Most records originate from stranding networks in California, Oregon, and Washington, though a few Alaska records of Eastern North Pacific gray whales (Eschrichtius robustus) are included, because this population is assessed in the Pacific region SARs and occurs along the U.S. west coast. Other marine mammals, such as Steller sea lions (Eumetopias jubatus), occur in California, Oregon, and Washington waters, but they are assessed in Alaska region SARs (Allen and Angliss 2014) and are not included in this report. Injury determinations for Pacific region species/stocks in the central Pacific from Hawaii westward are also included in separate reports (Bradford and Forney 2014).

description: Sexist speech is a pervasive issue on online social media platforms. Despite the ongoing development of increasingly sophisticated models for detecting sexist speech, the focus on the explainability and interpretability of these models remains limited. Automated tools can significantly aid in identifying sexism on a large scale. However, binary detection often overlooks the multifaceted nature of sexist content and fails to provide clear reasoning behind the classification of content as sexist. To address this issue, we present an ensemble model that is based on diverse pre-trained models. Our composite model leverages the power of its constituents by extracting relational information from the text by using different pre-trained models (BERT, XLMRoBERTa, DistilBERT) and passing it through a distinct Convolutional Neural Network (CNN) architecture. The design facilitates the integration of multiple techniques to improve the model's robustness and generalizability. To foster transparency, we apply explainable artificial intelligence techniques to discern the influence of individual tokens and various model components on the decision-making process. Moreover, we incorporate a feedback loop that involves human validation, where humans review and validate the model's predictions and explanations. This iterative approach enhances the model's rationality and alignment with human cognition. To continually evaluate the model's performance, we utilize explainability metrics. The result is a more reliable and interpretable model that aligns with human evaluation and contributes a comprehensive dataset in the field of sexism detection. This dataset, enriched with annotation and interpretability features, offers valuable insights into decision-making processes and serves as a robust foundation.

description: We perform a rigorous analysis of the quasineutral limit for a hydrodynamical model of a viscous plasma represented by the Navier Stokes Poisson system in $3-D$. We show that as $λ\to 0$ the velocity field $u^λ$ strongly converges towards an incompressible velocity vector field $u$ and the density fluctuation $ρ^λ-1$ weakly converges to zero. In general the limit velocity field cannot be expected to satisfy the incompressible Navier Stokes equation, indeed the presence of high frequency oscillations strongly affects the quadratic nonlinearities and we have to take care of self interacting wave packets. We shall provide a detailed mathematical description of the convergence process by using microlocal defect measures and by developing an explicit correctors analysis. Moreover we will be able to identify an explicit pseudo parabolic pde satisfied by the leading correctors terms. Our results include all the previous results in literature, in particular we show that the formal limit holds rigorously in the case of well prepared data.

description: We studied the new heavy-fermion system YbNi$_{4}$P$_{2}$, which presents strong ferromagnetic correlations, using the local $^{31}$P NMR probe over a wide field (0.2-8.6 \textsf{T}) and temperature (1.8-200 K) range. $^{31}$P NMR Knight shift provides the static spin susceptibility which tracks the bulk susceptibility whereas the spin-lattice relaxation rate $^{31}(1/T_{1}$) provide information about the fluctuations of the Yb 4f moment. The Korringa law is valid over a wide range in temperature and field. The Korringa product $^{31}(1/T_{1}TK^{2}$S$_{0}$) $\ll$ 1 gives evidence for the presence of strong ferromagnetic correlations. Over two decades in temperature a $^{31}(1/T_{1}T) \sim T^{-3/4}$ behaviour was found.

description: Considering Vaidya-Tikekar metric, we obtain a class of solutions of the Einstein-Maxwell equations for a charged static fluid sphere. The physical 3-space (t=constant) here is described by pseudo-spheroidal geometry. The relativistic solution for the theory is used to obtain models for charged compact objects, thereafter a qualitative analysis of the physical aspects of compact objects are studied. The dependence of some of the properties of a superdense star on the parameters of the three geometry is explored. We note that the spheroidicity parameter $a$, plays an important role for determining the properties of a compact object. A non-linear equation of state is required to describe a charged compact object with pseudo-spheroidal geometry which we have shown for known masses of compact objects. We also note that the size of a static compact charged star is more than that of a static compact star without charge.

description: We derive and analyze the dynamic equations for polar liquid crystals in two spatial dimensions in the framework of classical dynamical density functional theory (DDFT). Translational density variations, polarization, and quadrupolar order are used as order-parameter fields. The results are critically compared with those obtained using the macroscopic approach of time-dependent Ginzburg-Landau (GL) equations for the analogous order-parameter fields. We demonstrate that for both the microscopic DDFT and the macroscopic GL approach the resulting dissipative dynamics can be derived from a dissipation function. We obtain microscopic expressions for all diagonal contributions and for many of the cross-coupling terms emerging from a GL approach. Thus we establish a bridge between molecular correlations and macroscopic modeling for the dissipative dynamics of polar liquid crystals.

description: This research explores the lived experience of four women who range in age from their mid-thirties to early forties. The aim of this study is to broaden our understanding of the meaning of depersonalization to the women who experience it. The qualitative methodology of phenomenology was utilized. This method was guided by the theoretical framework of new paradigm research which strives to put a human element into research and feminist research which focuses on gender specific issues, including the concept of egalitarian relationships. The literature review explored dissociation disorders with respect to four areas: 1) early theories of depersonalization; 2) multiple personality disorder; 3) treatment of multiple personality; and 4) treatment of dissociation. The findings are presented as reduced stories of the women's experience. The essence of depersonalization was distilled from the stories of lived experience and this is presented in three theme clusters. The thematic clusters are: 1) defence of self, which includes the themes of control, coping and blocking; 2) self dispersion, with the themes of altered state of consciousness, going within and separation; and 3) self insight, which included knowing and awareness. Each cluster and theme is discussed using examples from the women's stories. The fear of insanity, while not a part of the experience, is discussed. This is presented in a feminist framework. Limitations and implications of the research are presented. Clinical implications for social work are addressed in two areas. First, clinical issues are explored for women who experience depersonalization as a coping mechanism. Secondly, clinical issues are discussed for women who live in violent relationships and experience depersonalization as a situational response.

description: We investigate numerically the effect of the competition of disorder, nonlinearity, and boundaries on the Anderson localization of light waves in finite-size, one-dimensional waveguide arrays. Using the discrete Anderson - nonlinear Schrödinger equation, the propagation of the mode amplitudes up to some finite distance is monitored. The analysis is based on the calculated localization length and the participation number, two standard measures for the statistical description of Anderson localization. For relatively weak disorder and nonlinearity, a higher disorder strength is required to achieve the same degree of localization at the edge than in the interior of the array, in agreement with recent experimental observations in the linear regime. However, for relatively strong disorder and/or nonlinearity, this behavior is reversed and it is now easier to localize an excitation at the edge than in the interior.

description: This thesis investigates a series of models of a dynamically balanced bipedal running robot. The simulation models are used to study the control of running height to aid the building of dynamically balanced legged systems. A simple mass on a spring model evolved into a complex system based on the use of a PID (ProportionalÂ­Integral-Derivative) controlled hydraulic actuator to inject energy into an air spring. The behaviour of hydraulic systems are nonlinear requiring detailed simulation. The simulation of these models is based on the study of the free body forces acting on the system. From the sum of these forces, a net acceleration is determined. A general simulation environment based on a fourth-order Runge-Kutta method, was implemented to solve the differential equations of motion. The thesis resulted in a biped model that can be accurately controlled to achieve a running height based only on the specification of a desired height.

description: We discuss the model dependence in the determination of the Wilson coefficient C_7 that governs the radiative electromagnetic decays of B mesons in the Standard Model, by considering various extensions of the effective Hamiltonian used to describe such decays. We include already measured observables like the branching ratios of B->X_s mu+ mu- and B->X_s gamma, the isospin and CP asymmetries in B->K* gamma, as well as A_FB and F_L in B->K* l+ l-, adding the LHCb measurements presented at this conference. We explore the constraints on C_7,C_9,C_10 as well as their chirality-flipped counterparts. We also discuss the transverse asymmetry A_T^2 which, once measured, may help to disentangle some of the scenarios considered.

description: A stochastic model for the dynamics of enzymatic catalysis in explicit, effective solvents under physiological conditions is presented. Analytically-computed first passage time densities of a diffusing particle in a spherical shell with absorbing boundaries are combined with densities obtained from explicit simulation to obtain the overall probability density for the total reaction cycle time of the enzymatic system. The method is used to investigate the catalytic transfer of a phosphoryl group in a phosphoglycerate kinase-ADP-bis phosphoglycerate system, one of the steps of glycolysis. The direct simulation of the enzyme-substrate binding and reaction is carried out using an elastic network model for the protein, and the solvent motions are described by multiparticle collision dynamics, which incorporates hydrodynamic flow effects. Systems where solvent-enzyme coupling occurs through explicit intermolecular interactions, as well as systems where this coupling is taken into account by including the protein and substrate in the multiparticle collision step, are investigated and compared with simulations where hydrodynamic coupling is absent. It is demonstrated that the flow of solvent particles around the enzyme facilitates the large-scale hinge motion of the enzyme with bound substrates, and has a significant impact on the shape of the probability densities and average time scales of substrate binding for substrates near the enzyme, the closure of the enzyme after binding, and the overall time of completion of the cycle.

Response of a circumbinary accretion disc to black hole mass loss

description: We investigate the evolution of the surface density of a circumbinary accretion disc after the mass loss induced by the merger of two supermassive black holes. We first introduce an analytical model, under the assumption of a disc composed of test particles, to derive the surface density evolution of the disc following the mass loss. The model predicts the formation of sharp density peaks in the disc; the model also allows us to compute the typical timescale for the formation of these peaks. To test and validate the model, we run numerical simulations of the process using the Smoothed Particle Hydrodynamics (SPH) code PHANTOM, taking fluid effects into account. We find good agreement in the shape and position of the peaks between the model and the simulations. In a fluid disc, however, the epicyclic oscillations induced by the mass loss can dissipate, and only some of the predicted peaks form in the simulation. To quantify how fast this dissipation proceeds, we introduce an appropriate parameter, and we show that it is effective in explaining the differences between the analytical, collisionless model and a real fluid disc.

Spin- and band-ferromagnetism in trilayer graphene

description: We study the ground state properties of an ABA-stacked trilayer graphene. The low energy band structure can be described by a combination of both a linear and a quadratic particle-hole symmetric dispersions, reminiscent of monolayer- and bilayer-graphene, respectively. The multi-band structure offers more channels for instability towards ferromagnetism when the Coulomb interaction is taken into account. Indeed, if one associates a pseudo-spin 1/2 degree of freedom to the bands (parabolic/linear), it is possible to realize also a band-ferromagnetic state, where there is a shift in the energy bands, since they fill up differently. By using a variational procedure, we compute the exchange energies for all possible variational ground states and identify the parameter space for the occurrence of spin- and band-ferromagnetic instabilities as a function of doping and interaction strength.

description: Recent X-ray observations of the supernova remnant IC443 interacting with molecular clouds have shown the presence of a new population of hard X-ray sources related to the remnant itself, which has been interpreted in terms of fast ejecta fragment propagating inside the dense environment. Prompted by these studies, we have obtained a deep {\sl XMM-Newton} observation of the supernova remnant (SNR) Kes 69, which also shows signs of shock-cloud interaction. We report on the detection of 18 hard X-ray sources in the field of Kes 69, a significant excess of the expected galactic source population in the field, spatially correlated with CO emission from the cloud in the remnant environment. The spectra of 3 of the 18 sources can be described as hard power laws with photon index <2 plus line emission associated to K-shell transitions. We discuss the two most promising scenarios for the interpretation of the sources, namely fast ejecta fragments (as in IC443) and cataclysmic variables. While most of the observational evidences are consistent with the former interpretation, we cannot rule out the latter.

Success-driven distribution of public goods promotes cooperation but preserves defection

description: Established already in the Biblical times, the Matthew effect stands for the fact that in societies rich tend to get richer and the potent even more powerful. Here we investigate a game theoretical model describing the evolution of cooperation on structured populations where the distribution of public goods is driven by the reproductive success of individuals. Phase diagrams reveal that cooperation is promoted irrespective of the uncertainty by strategy adoptions and the type of interaction graph, yet the complete dominance of cooperators is elusive due to the spontaneous emergence of super-persistent defectors that owe their survival to extremely rare microscopic patterns. This indicates that success-driven mechanisms are crucial for effectively harvesting benefits from collective actions, but that they may also account for the observed persistence of maladaptive behavior.

description: The management of municipal solid waste in an environmentally safe and economically efficient manner has become a growing concern in Canada. Poor management and overburdened landfills have become increasingly serious problems in many cities, resulting in the need for comprehensive and objective evaluations of current practices to direct and improve future initiatives. Impending federal waste reduction legislation requires substantial reductions in the amount of refuse landfilled by 2000. Municipalities relying heavily upon landfilling for waste disposal must investigate techniques for improving effectiveness and efficiency of current waste management procedures, and examine alternative methods for managing municipal solid waste. Calgary, Alberta employs sanitary landfilling exclusively to fulfill municipal solid waste disposal requirements in the City. landfill operations appeared to pose little threat of environmental pollution. However, outstanding issues surrounding compliance with provincial waste legislation requires further attention. As greater emphasis is given to diverting solid waste from landfills, cities such as Calgary must investigate alternative waste management options such as incineration, recycling, and composting to decrease landfilled wastes and implement waste minimization programs. Prior to adopting new waste management methods, current waste management techniques must be evaluated to determine the appropriate direction of future initiatives.
