description: The first modern edition of William of Tyre's Historia was published in 1844. However, the 12th chapter of the 19th book of the Historia was lost at that time. R. B. C. Huygens discovered it and announced the discovery in 1962. In this autobiographical chapter, William mainly talks about his education in Europe. He also mentions his first service in the Church of Acre after returning to the Kingdom of Jerusalem and his first contact with the royal family. With the discovery of the chapter, an important phase of William of Tyre's life is enlightened. Although the Turkish translation of the Historia was published after the discovery of the chapter, the chapter is not included in the translation. To fill the gap, the chapter is translated into Turkish in this study.

description: In this paper we extend our techniques, developed in a previous paper (Du, etc, JHEP 05(2016)086) for direct evaluation of arbitrary $n$-point tree-level MHV amplitudes in 4d Yang-Mills and gravity theory using the Cachazo-He-Yuan (CHY) formalism, to the 4d Einstein-Yang-Mills (EYM) theory. Any single-trace color-ordered $n$-point tree-level MHV amplitude in EYM theory, obtained by a direct evaluation of the CHY formula, is of an elegant factorized form of a Parke-Taylor factor and a Hodges determinant, much simpler and more compact than the existing formulas in the literature. We prove that our new expression is equivalent to the conjectured Selivanov-Bern-De Freitas-Wong (SBDW) formula, with the help of a new theorem showing that the SBDW generating function has a graph theory interpretation. Together with Ref. (Du, etc, JHEP 05(2016)086), we provide strong analytic evidence for hidden simplicity in quantum field theory.

description: Every consumers' in the market has his/her own brand preference. Dairy product consider certain factor affecting before purchasing products. The objective of this study was to analyze the factors affecting consumers' brand preference in Fiche town and area. The independent variables included in this study are price, product quality, advertisement, brand name awareness and brand availability; while brand preference is the dependent variable. The objective of this study was to examine consumers' consume pattern for different dairy products (fluid milk, butter, cheese, yoghurt Butter milk/Arera/), and to assess the factors affecting consumers' brand preference for dairy product in Fiche town and area. Different literatures have been used in discussing the concept and to identify major factors that affect consumer brand preference. Questionnaires were distributed to sample respondents using structured questionnaire interview administered by the researcher to 382 consumers' the Council housing units using dairy products. The respondent were sampled based on simple random sampling and consumer were sampled using Council housing units as this study, one housing unit represented one person method. Both descriptive and ANOVA, two tailed t- test and multiple regression. The findings indicate that consumers' using purchase of dairy products increased significantly for fluid milk and moderately for other products (butter, cheese yogurt and butter milk/Arera ) while Particularly fluid milk and butter were found to be the most preferred brand among all dairy brands in Fiche town and area. Marital status, gender, income and occupation are found to be the demographic variables affecting consumers brand preferences significantly. Product/brand and center most factor affecting consumers brand preference significantly are: prices and product quality. Recommendations for business sector and policy makers were made and future research area suggested considering contextual issues for Ethiopian dairy brand consumers. On dairy cooperative and small scale enterprise play a vital role for the success of Fiche town and area dairy cooperative and small scale enterprise. Therefore, there must be training for management and the management must be willing to use modern value added technologies such as diversification of processed products by focusing on factor affect consumers' brand preference.

description: We introduce a new information theoretic measure of quantum correlations for multiparticle systems. We use a form of multivariate mutual information -- the interaction information and generalize it to multiparticle quantum systems. There are a number of different possible generalizations. We consider two of them. One of them is related to the notion of quantum discord and the other to the concept of quantum dissension. This new measure, called dissension vector, is a set of numbers -- quantumness vector. This can be thought of as a fine-grained measure, as opposed to measures that quantify some average quantum properties of a system. These quantities quantify/characterize the correlations present in multiparticle states. We consider some multiqubit states and find that these quantities are responsive to different aspects of quantumness, and correlations present in a state. We find that different dissension vectors can track the correlations (both classical and quantum), or quantumness only. As physical applications, we find that these vectors might be useful in several information processing tasks. We consider the role of dissension vectors -- (a) in deciding the security of BB84 protocol against an eavesdropper and (b) in determining the possible role of correlations in the performance of Grover search algorithm. Especially, in the Grover search algorithm, we find that dissension vectors can detect the correlations and show the maximum correlations when one expects.

description: The lack of large video databases obtained from real patients with respiratory disorders makes the design and optimization of video-based monitoring systems quite critical. The purpose of this study is the development of suitable models and simulators of breathing behaviors and disorders, such as respiratory pauses and apneas, in order to allow efficient design and test of video-based monitoring systems. More precisely, a novel Continuous-Time Markov Chain (CTMC) statistical model of breathing patterns is presented. The Respiratory Rate (RR) pattern, estimated by measured vital signs of hospital-monitored patients, is approximated as a CTMC, whose states and parameters are selected through an appropriate statistical analysis. Then, two simulators, software- and hardware-based, are proposed. After validation of the CTMC model, the proposed simulators are tested with previously developed video-based algorithms for the estimation of the RR and the detection of apnea events. Examples of application to assess the performance of systems for video-based RR estimation and apnea detection are presented. The results, in terms of Kullback-Leibler divergence, show that realistic breathing patterns, including specific respiratory disorders, can be accurately described by the proposed model; moreover, the simulators are able to reproduce practical breathing patterns for video analysis. The presented CTMC statistical model can be strategic to describe realistic breathing patterns and devise simulators useful to develop and test novel and effective video processing-based monitoring systems.

Year: 2017
Subjects: subject: Differential Geometry (math.DG)
subject: FOS: Mathematics

description: Let the circle act on a compact almost complex manifold $M$. In this paper, we classify the fixed point data of the action if there are 4 fixed points and the dimension of the manifold is at most 6. First, if $\dim M=2$, then $M$ is a disjoint union of rotations on two 2-spheres. Second, if $\dim M=4$, we prove that the action alikes a circle action on a Hirzebruch surface. Finally, if $\dim M=6$, we prove that six types occur for the fixed point data; $\mathbb{CP}^3$ type, complex quadric in $\mathbb{CP}^4$ type, Fano 3-fold type, $S^6 \cup S^6$ type, and two unknown types that might possibly be realized as blow ups of a manifold like $S^6$. When $\dim M=6$, we recover the result by Ahara in which the fixed point data is determined if furthermore $\mathrm{Todd}(M)=1$ and $c_1^3(M)[M] \neq 0$, and the result by Tolman in which the fixed point data is determined if furthermore the base manifold admits a symplectic structure and the action is Hamiltonian.

description: We have analyzed images from the VST ATLAS survey to identify candidate gravitationally lensed quasar systems in a sample of WISE sources with W1 - W2 > 0.7. Results from followup spectroscopy with the Baade 6.5 m telescope are presented for eight systems. One of these is a quadruply lensed quasar and two are doubly lensed systems. Two are projected superpositions of two quasars at different redshifts. In one system two quasars, though at the same redshift, have very different emission line profiles, and constitute a physical binary. In two systems the component spectra are consistent with the lensing hypothesis, after allowing for micro-lensing. But as no lensing galaxy is detected in these two, we classify them as lensless twins. More extensive observations are needed to establish whether they are in fact lensed quasars or physical binaries.

In this paper we solve this open problem by finding the packing number of the double vertex graph (2-token graph) of a path graph. This double vertex graph is isomorphic to the Sloane's graph. Our solution implies a conjecture of Rob Pratt about the ordinary generating function of sequence A085680.

description: The orbital angular momentum and the polarisation of light are physical quantities widely investigated for classical and quantum information processing. In this work we propose to take advantage of strong light-matter coupling, circular-symmetric confinement, and transverse-electric transverse-magnetic splitting to exploit states where these two degrees of freedom are combined. To this end we develop a model based on a spin-orbit Poincaré hypersphere. Then we consider the example of semiconductor polariton systems and demonstrate full ultrafast Stark control of spin-orbit states. Moreover, by controlling states on three different spin-orbit spheres and switching from one sphere to another we demonstrate the control of different logic bits within one single physical system.

description: The aim of this study was to assess the marketing strategy practice, identify challenges and provide possible recommendation to the identified challenges. It tries to identify the process the company follows in the formulation of marketing strategy, how segmentation and targeting is being practices, the choice of the marketing mix elements and the challenges experienced by the company in the implementation of the marketing strategy. The research design was descriptive and qualitative approach was used. The research was carried out using both primary and secondary source of data to get the intended data and meet the objective of the study. To gather the primary data semi structured questionnaire where used for an interview with purposively selected sample size 18 management from divisions responsible for formulation and implementation of the strategy. For the secondary data, of the company's planning document is used to understand the marketing strategy formulation process. Data was collected through one to one and telephone interview and self-administered questionnaire. The finding of the analysis shows; the company follow well-structured process in the formulation of the marketing strategy. With regards to segmentation and targeting, apart from an effort in trying to define the segments in the market, it is not fully implemented and there is lack of consistency across the application of segmentation in the company. The gaps on segmentation practice further affects the practice of targeting, although the company have many products and services it is not able to ensure delivery of tailored products for differentially segmented customers. The company has also well exploited the 4 marketing mix elements such as product, price, place and promotion with inadequate focus on three elements people, process and physical evidence. The main challenges in the implementation are also identified to be lack of attention, focus and poor integration by the management and working units, lack of knowledge and system readiness, lengthy and inefficient procurement and decision making process Accordingly, it is recommended by the researcher for the company to strengthen internal communication and create better alignment , empower management and ensure timely decision build its capacity hiring expertise on the industry and implementing data analytical tool to support segmentation, include the 3Ps in the marketing mix elements to ensure customer centricity of internal process, procedure and decision making

description: A classical theorem of Malykhin says that if $\{X_α:α\leqκ\}$ is a family of compact spaces such that $t(X_α)\leq κ$, for every $α\leqκ$, then $t\left( \prod_{α\leq κ} X_α\right)\leq κ$, where $t(X)$ is the tightness of a space $X$. In this paper we prove the following counterpart of Malykhin's theorem for functional tightness: Let $\{X_α:α<λ\}$ be a family of compact spaces such that $t_0(X_α)\leq κ$ for every $α<λ$. If $λ\leq 2^κ$ or $λ$ is less than the first measurable cardinal, then $t_0\left( \prod_{α<λ} X_α\right)\leq κ$, where $t_0(X)$ is the functional tightness of a space $X$. In particular, if there are no measurable cardinals, then the functional tightness is preserved by arbitrarily large products of compacta. Our result answers a question posed by Okunev.

description: We consider an alternating Heisenberg spin-$1/2$ antiferromagnetic-ferromagnetic ($AF-F$) chain with the space modulated dominant antiferromagnetic exchange and anisotropic ferromagnetic coupling (tetrameric spin-$1/2$ chain). The zero-temperature effect of a symmetry breaking transverse magnetic field on the model is studied numerically. It is found that the anisotropy effect on the ferromagnetic coupling induces two new gapped phases. We identified their orderings as a kind of the stripe-antiferromagnetic phase. As a result, the magnetic phase diagram of the tetrameric chain shows five gapped quantum phases and the system is characterized by four critical fields which mark quantum phase transitions in the ground state of the system with the changing transverse magnetic field. We have also exploited the well known bipartite entanglement (name as concurrence) and global entanglement tools to verify the occurrence of quantum phase transitions and the corresponding critical points.

description: The purpose of the study was to assess the practice of public procurement planning and Implementation (PPI) in Ethiopia, in the case of Public Procurement and property disposal Service (PPDS). The methodology used was both qualitative and quantitative methods, using descriptive techniques to discuss and interpret data. The study population was 120 staffs of PPDS of which the target population was 24 staffs working on procurement core process and five federal PB's as end users. The sample size of 20 staffs were selected from target using purposive sampling techniques from procuring entity and 5 staffs from end users were selected from sector ministries. The Questionnaires, in-depth interview and document review were used to collect data. The techniques used to analyze data were, frequency and percentage using Microsoft excel. The finding reveals that limited capacity in conducting needs assessment, description of needs, and late submission of requirements, insufficient staffing of procurement unit in terms of number and skill required, limited quality training in planning activities and preparation of procurement document at each stage, inadequate review procedure of requirement submitted by PB's, lack of practice in announcement of annual procurement plan, limited capacity: in conducting market survey, in costing and scheduling procurement activities, contract management, and monitoring; shortage and turnover of qualified professional, lack of using PP as management and monitoring tools, limited practice in periodic review of effectiveness in planning and implementation of public procurement, limited experience of using some procurement methods, submission of substandard requirement in terms of specification/TOR/SOW, limited interest to participate in open bidding by most suppliers/contractors and limited capacity of supplier to deliver as per contract and inadequate availability of foreign currency are among others. Based on the findings, following are major recommendations: procurement unit need to be staffed with qualified and trained personals, collaborate with knowledge center to improve skills and competencies of workforce, avail resource and facility to professionals, adopt comprehensive procurement planning documents, regularly provide quality training in all aspect, implement practice of conducting market survey and update market information and supplier list and apply oversight and control mechanism to support accountability throughout procurement cycle and create awareness and collaborate with key stakeholders at different level, enforce submission of requirement as per timeline of directive, and establish a mechanism to conduct periodic assessment and consistently the result of procurement planning, process and system

description: Global change drivers (e.g. climate and land-use) affect the species and functional traits observed in a local site but also its dark diversity—the set of species and traits locally suitable but absent. Dark diversity links regional and local scales and, over time, reveals taxa under expansion lags by depicting the potential biodiversity that remains suitable but is absent locally. Since global change effects on biodiversity are both spatially and temporally scale dependent, examining long-term temporal dynamics in observed and dark diversity would be relevant to assessing and foreseeing biodiversity change. Here, we used sedimentary pollen data to examine how both taxonomic and functional observed and dark diversity changed over the past 14 500 years in northern Europe. We found that taxonomic and functional observed and dark diversity increased over time, especially after the Late Glacial and during the Late Holocene. However, dark diversity dynamics revealed expansion lags related to species' functional characteristics (dispersal limitation and stress intolerance) and an extensive functional redundancy when compared to taxa in observed diversity. We highlight that assessing observed and dark diversity dynamics is a promising tool to examine biodiversity change across spatial scales, its possible causes, and functional consequences.

Moreover, by using this characterization, we consider when Cayley sums and Minkowski sums of $2$-convex-normal lattice polytopes have the integer decomposition property. Finally, we also discuss the level property for Minkowski sums and Cayley sums.

The key point is that the twists are allowed to be meromorphic. This weakened analytic assumption applies in the context of our second theorem, which shows that the quotient of the symmetric square L-function of a Maass newform and the Riemann zeta function has infinitely many poles.

description: We show that an ansatz based on independent composite bosons [Phys. Rep. 463, 215 (2008)] accurately describes the condensate fraction of molecular Bose-Einstein condensates in ultracold Fermi gases. The entanglement between the fermionic constituents of a single Feshbach molecule then governs the many-particle statistics of the condensate, from the limit of strong interaction to close to unitarity. This result strengthens the role of entanglement as the indispensable driver of composite-boson behavior. The condensate fraction of fermion pairs at zero temperature that we compute matches excellently previous results obtained by means of fixed-node diffusion Monte Carlo methods and the Bogoliubov depletion approximation. This paves the way towards the exploration of the BEC-BCS crossover physics in mixtures of cold Fermi gases with an arbitrary number of fermion pairs as well as the implementation of Hong-Ou-Mandel-like interference experiments proposed within coboson theory.

We find that structure in voids as traced by faint galaxies is mildly non-linear as compared with the general population of galaxies with similar luminosities. This implies a redshift-space correlation function with a similar shape than the real-space correlation albeit a normalization factor. The redshift space distortions of void galaxies allow to calculate pairwise velocity distributions which are consistent with an exponential model with a pairwise velocity dispersion of $w \sim 50-70$ km/s, significantly lower than the global value of $w \sim 500$ km/s. We also find that the internal structure of voids as traced by faint galaxies is independent of void environment, namely the correlation functions of galaxies residing in void-in-void or void-in-shell regions are identical within uncertainties. We have tested all our results with the semi-analytic catalogue MDPL2-\textsc{Sag} finding a suitable agreement with the observations in all topics studied.

description: Global change drivers (e.g. climate and land-use) affect the species and functional traits observed in a local site but also its dark diversity—the set of species and traits locally suitable but absent. Dark diversity links regional and local scales and, over time, reveals taxa under expansion lags by depicting the potential biodiversity that remains suitable but is absent locally. Since global change effects on biodiversity are both spatially and temporally scale dependent, examining long-term temporal dynamics in observed and dark diversity would be relevant to assessing and foreseeing biodiversity change. Here, we used sedimentary pollen data to examine how both taxonomic and functional observed and dark diversity changed over the past 14 500 years in Northern Europe. We found that taxonomic and functional observed and dark diversity increased over time, especially after the Late Glacial and during the Late Holocene. However, dark diversity dynamics revealed expansion lags related to species' functional characteristics (dispersal limitation and stress intolerance) and an extensive functional redundancy when compared to taxa in observed diversity. We highlight that assessing observed and dark diversity dynamics is a promising tool to examine biodiversity change across spatial scales, its possible causes, and functional consequences.
Interplay of Site and Bond Electron-Phonon Coupling in One Dimension

description: The interplay of bond and charge correlations is studied in a one-dimensional model with both Holstein and Su-Schrieffer-Heeger (SSH) couplings to quantum phonons. The problem is solved exactly by quantum Monte Carlo simulations. If one of the couplings dominates, the ground state is a Peierls insulator with long-range bond or charge order. At weak coupling, the results suggest a spin-gapped and repulsive metallic phase arising from the competing order parameters and lattice fluctuations. Such a phase is absent from the pure SSH model even for quantum phonons. At strong coupling, evidence for a continuous transition between the two Peierls states is presented.

description: Myxoid liposarcoma (MLS) represents a common subtype of liposarcoma molecularly characterized by a recurrent chromosomal translocation that generates a chimeric FUS-DDIT3 fusion gene. The FUS-DDIT3 oncoprotein has been shown to be crucial in MLS pathogenesis. Acting as a transcriptional dysregulator, FUS-DDIT3 stimulates proliferation and interferes with adipogenic differentiation. As the fusion protein represents a therapeutically challenging target, a profound understanding of MLS biology is elementary to uncover FUS-DDIT3-dependent molecular vulnerabilities. Recently, a specific reliance on the Hippo pathway effector and transcriptional co-regulator YAP1 was detected in MLS; however, details on the molecular mechanism of FUS-DDIT3-dependent YAP1 activation, and YAP1´s precise mode of action remain unclear. In elaborate in vitro studies, employing RNA interference-based approaches, small-molecule inhibitors, and stimulation experiments with IGF-II, we show that FUS-DDIT3-driven IGF-IR/PI3K/AKT signaling promotes stability and nuclear accumulation of YAP1 via deregulation of the Hippo pathway. Co-immunoprecipitation and proximity ligation assays revealed nuclear co-localization of FUS-DDIT3 and YAP1/TEAD in FUS-DDIT3-expressing mesenchymal stem cells and MLS cell lines. Transcriptome sequencing of MLS cells demonstrated that FUS-DDIT3 and YAP1 co-regulate oncogenic gene signatures related to proliferation, cell cycle progression, apoptosis, and adipogenesis. In adipogenic differentiation assays, we show that YAP1 critically contributes to FUS-DDIT3-mediated adipogenic differentiation arrest. Taken together, our study provides mechanistic insights into a complex FUS-DDIT3-driven network involving IGF-IR/PI3K/AKT signals acting on Hippo/YAP1, and uncovers substantial cooperative effects of YAP1 and FUS-DDIT3 in the pathogenesis of MLS.

description: We propose a systematic procedure to optimize quantum state tomography protocols for continuous variable systems based on excitation counting preceded by a displacement operation. Compared with conventional tomography based on Husimi or Wigner function measurement, the excitation counting approach can significantly reduce the number of measurement settings. We investigate both informational completeness and robustness, and provide a bound of reconstruction error involving the condition number of the sensing map. We also identify the measurement settings that optimize this error bound, and demonstrate that the improved reconstruction robustness can lead to an order of magnitude reduction of estimation error with given resources. This optimization procedure is general and can incorporate prior information of the unknown state to further simplify the protocol.

description: We develop original models to study interacting agents in financial markets and in social networks. Within these models randomness is vital as a form of shock or news that decays with time. Agents learn from their observations and learning ability to interpret news or private information in time-varying networks. Under general assumption on the noise, a limit theorem is developed for the generalised DeGroot framework for certain type of conditions governing the learning. In this context, the agents beliefs (properly scaled) converge in distribution that is not necessarily normal. Fresh insights are gained not only from proposing a new setting for social learning models but also from using different techniques to study discrete time random linear dynamical systems.

description: This is an overview of higher structural constructions in physics. The main motivations of our current attempt are as follows: (i) to provide a brief introduction to derived algebraic geometry, (ii) to understand how derived objects naturally appear in physics and give rise to formal mathematical treatment, and (iii) to investigate how factorization algebras together with certain higher categorical structures come into play to encode the structure of observables in physics. Adopting such a heavy and relatively enriched language allows us to formalize the notions of quantization and observables in quantum field theory as well. This document is organized to examine each task listed above in an expository manner.
