description: We study security games in which a defender commits to a mixed strategy for protecting a finite set of targets of different values. An attacker, knowing the defender's strategy, chooses which target to attack and for how long. If the attacker spends time $t$ at a target $i$ of value $α_i$, and if he leaves before the defender visits the target, his utility is $t \cdot α_i $; if the defender visits before he leaves, his utility is 0. The defender's goal is to minimize the attacker's utility. The defender's strategy consists of a schedule for visiting the targets; it takes her unit time to switch between targets. Such games are a simplified model of a number of real-world scenarios such as protecting computer networks from intruders, crops from thieves, etc. We show that optimal defender play for this continuous time security games reduces to the solution of a combinatorial question regarding the existence of infinite sequences over a finite alphabet, with the following properties for each symbol $i$: (1) $i$ constitutes a prescribed fraction $p_i$ of the sequence. (2) The occurrences of $i$ are spread apart close to evenly, in that the ratio of the longest to shortest interval between consecutive occurrences is bounded by a parameter $K$. We call such sequences $K$-quasi-regular. We show that, surprisingly, $2$-quasi-regular sequences suffice for optimal defender play. What is more, even randomized $2$-quasi-regular sequences suffice for optimality. We show that such sequences always exist, and can be calculated efficiently. The question of the least $K$ for which deterministic $K$-quasi-regular sequences exist is fascinating. Using an ergodic theoretical approach, we show that deterministic $3$-quasi-regular sequences always exist. For $2 \leq K < 3$ we do not know whether deterministic $K$-quasi-regular sequences always exist.

Major general of probiotic bacteria that promote plant growth include Bacillus, Pseudomonas, Acinetobacter, Arthrobacter and Serratia (Rahman et al., 2018).In addition, some PGPR strains are effective in suppressing pest, pathogen and effective as biocontrol agents. Study reported that various Bacillus strains are important in controlling pathogens and improving plant growth due to antagonistic relationships (Rahman et al., 2018). A previous study also showed that PGPR is involved in the production of plant hormones such as indole acetic acid (IAA). The bacteria species most studied and likely to produce this compound are Bradyrhizobium japonicum SB-1 and Bradyrhizobium thuringiensis (Asghari et al., 2020). This study determined the reproducibility of using three plant probiotics strains (Isolate 4 (Acinetobacter pittii), Isolate 9 (Bacillus altitudinis), and Isolate 8 (Bacillus licheniformis)) on the plant growth of curly kale, Jericho lettuce and Thai basil seeds.

description: Scalar-Tensor-Vector Gravity (STVG) is a theory that does not require dark components to describe astrophysical data. We aim at constraining the free parameters of STVG based on recent observations of the jet in M87. We derive the equations of motion for particles in STVG-Kerr spacetime, we develop a numerical code that integrates such equations, and apply it to the jet of M87. We find that STVG deviates from GR and we set new upper limits for the free parameters of the former. We conclude that STVG is not contradicted by the observational data of M87, and may help to explain jet formation.

description: Localizability of entanglement in fully inseparable states is a key ingredient of assisted quantum information protocols as well as measurement-based models of quantum computing. We investigate the existence of fully inseparable states with nonlocalizable entanglement, that is, with entanglement which cannot be localized between any pair of subsystems by any measurement on the remaining part of the system. It is shown, that the nonlocalizable entanglement occurs already in suitable mixtures of a three-qubit GHZ state and white noise. Further, we generalize this set of states to a two-parametric family of fully inseparable three-qubit states with nonlocalizable entanglement. Finally, we demonstrate experimentally the existence of nonlocalizable entanglement by preparing and characterizing one state from the family using correlated single photons and linear optical circuit.

Multivariate alternating decision tree

Subjects: Uncategorized

description: Decision trees are characterized by fast induction time and comprehensible classification rules. However, their classification accuracies are relatively lower in comparison to other black-box classifiers such as support vector machines. It is often possible to improve decision tree accuracies by combining them via boosting or bagging to form an ensemble of trees (i.e., forests). Unfortunately, ensemble approaches will cause the decision trees to lose their comprehensibility and significantly lengthen their induction time. The invention of the alternating decision tree (ADTree) allows the incorporation of boosting within a single decision tree to retain comprehensibility. However, the existing ADTree is univariate in nature which limits its potential to further improve the accuracy and induction time. This thesis presents the multivariate alternating decision tree, whereby multivariate decision nodes are incorporated into the ADTree learning algorithm. It can be considered as a generalization of the existing univariate ADTree. Three different variants of multivariate ADTrees are presented in this thesis, namely the Fisher’s ADTree, Sparse ADTree and regularized LogitBoost ADTree (rLADTree). These algorithms were benchmarked against other existing univariate, multivariate and ensemble-based decision trees using real-world datasets from the University of California, Irvine Machine Learning Repository and University of Eastern Finland Spectral Database. It is shown that the Fisher’s ADTree is capable of improving the accuracy of multivariate decision trees through boosting. At the same time it remains to be significantly smaller than boosted multivariate decision trees. It is also shown that the Sparse ADTree is a non-parametric extension of the Sparse Linear Discriminant Analysis (SLDA). It is therefore able to linearly partition the data when it is beneficial to do so, or to grow a tree to improve the classification accuracy when necessary. The most notable multivariate ADTree variant is the regularized LADTree, which is characterized by having no statistically significant differences in all performance metrics and offering comprehensibility when compared with the univariate, unboosted decision trees like C4.5 and CART for general datasets. For datasets with highly correlated features, the regularized LADTree outperforms the existing decision trees in terms of accuracy and comprehensibility, making it a top choice among decision tree classifiers.

Deciphering the Enigma of Wave-Particle Duality

Publisher: name: arXiv
Year: 2016
Subjects: subject: General Physics (physics.gen-ph)
subject: FOS: Physical sciences

description: A reasonable explanation of the confounding wave-particle duality of matter is presented in terms of the reality of the wave nature of a particle. In this view a quantum particle is an objectively real wave packet consisting of irregular disturbances of underlying quantum fields. It travels holistically as a unit and thereby acts as a particle. Only the totality of the entire wave packet at any instance embodies all the conserved quantities, for example the energy-momentum, rest mass, and charge of the particle, and as such must be acquired all at once during detection. On this basis, many of the bizarre behaviors observed in the quantum domain, such as wave function collapse, the limitation of prediction to only a probability rather than a certainty, the apparent simultaneous existence of a particle in more than one place, and the inherent uncertainty can be adequately understood. The reality of comprehending the wave function as an amplitude distribution of irregular disturbances imposes the necessity of acquiring the wave function in its entirety for detection. This is evinced by the observed certainty of wave function collapse that supports the paradigm of reality of the wave function portrayed in this article.

description: TeV-range cosmic ray electrons and positrons (CREs) have been directly measured in the search for new physics or unknown astrophysical sources. CREs can inverse-Compton scatter solar photons and boost their energies into gamma ray bands. Any potential CRE excess would enhance the resultant inverse Compton emission spectrum in the relevant energy range, offering a new window to verify the measured CRE spectrum. In this paper, we show that an excess in the TeV range of the CRE spectrum, such as the one indicated by the DAMPE experiment, can induce a characteristic solar gamma ray signal. Accounting for contamination from extragalactic gamma ray backgrounds (EGB), we forecast the DAMPE feature is testable ($\gtrsim 4 σ$) with a $\sim 10^{5}\,\mathrm{m}^2\,{\rm yr}$ exposure in the off-disk direction. This can be achieved by long-exposure observations of water Cherenkov telescopes, such as LHAASO (7.2 years) and HAWC (25.9 years).

Mixing of fluids and suspensions in a laminar stirred tank

description: Mechanically agitated vessels are widely used unit operations in the modern processing industry. Mixing vessels are critical for bulk materials chemical slurry processing such as leaching, digestion, crystallization, adsorption, ion-exchange and polymerization. Homogeneous mixing is vital for product blending consistency and purity of the reaction products. Inconsistent solute distribution and non-homogeneous blending due to poor mixing can lead to undesirable by-product which is often unacceptable in terms of product quality. One distinctive phenomenon related to poor mixing in a stirred vessel is the formation of isolated mixing regions. Isolated mixing regions or IMRs refer to regions of confined mixed zone, segregated by well-defined boundary layer. The present work is driven by a need to eliminate IMRs at high viscosities with practical engineering designs. Experiments were carried out in a small perspex tank. The features of the IMRs formed in the viscous Newtonian systems in a stirred tank have been studied. Homogeneous mixing can be achieved via some geometrical modifications including baffle installation and addition of particles, via completely eliminating the isolated mixing regions. The experimental and CFD results confirmed that the breaking spatial symmetry in the angled-shaft system leads to destruction of the isolated mixing regions. A new particle-localization phenomenon has been discovered in a solid-liquid laminar mixing tank, and the mechanism has been uncovered from the prospective of dynamical systems. The results demonstrated that sufficiently straining flow combined with the presence of separated flow regions (i.e IMRs) are the necessary conditions for particle clustering and the particles cluster into the IMRs when the total fluid strain on a particle exceeds a critical value that depends on the particle and fluid inertia. A facile separation strategy using a highly novel particle-location-manipulation physics has been successfully developed, and several methods have been proposed to improve the mixing in the solid-liquid slurry system.

Gradient flow for the Boltzmann entropy and Cheeger's energy on time-dependent metric measure spaces
Creators: name: Kopfer, Eva
Publisher: name: arXiv
Year: 2016
Subjects: subject: Probability (math.PR)
subject: FOS: Mathematics

description: We introduce notions of dynamic gradient flows on time-dependent metric spaces as well as on time-dependent Hilbert spaces. We prove existence of solutions for a class of time dependent energy functionals in both settings. In particular we are interested in the case when the underlying spaces are metric measure spaces and the energy functional is given by the time-dependent Boltzmann entropy or the time-dependent Cheeger's energy. Under the assumption that each static space satisfies a lower Ricci curvature bound, we prove existence and uniqueness of the entropy gradient flow and we identify it with the forward adjoint heat flow introduced in "Super-Ricci Flows for Metric Measure Spaces" by Kopfer/Sturm. We identify the gradient flow for the time-dependent Cheeger's energy with the heat flow introduced by Kopfer/Sturm.

description: This paper is aimed at evaluating state-of-the-art models for Multi-document Summarization (MDS) on different types of datasets in various domains and investigating the limitations of existing models to determine future research directions. To address this gap, we conducted an extensive literature review to identify state-of-the-art models and datasets. We analyzed the performance of PRIMERA and PEGASUS models on BigSurvey-MDS and MS$^2$ datasets, which posed unique challenges due to their varied domains. Our findings show that the General-Purpose Pre-trained Model LED outperforms PRIMERA and PEGASUS on the MS$^2$ dataset. We used the ROUGE score as a performance metric to evaluate the identified models on different datasets. Our study provides valuable insights into the models' strengths and weaknesses, as well as their applicability in different domains. This work serves as a reference for future MDS research and contributes to the development of accurate and robust models which can be utilized on demanding datasets with academically and/or scientifically complex data as well as generalized, relatively simple datasets.

description: Hydroxyapatite [Ca1o(PO)s(OH)z] is an integral part of the body found predominantly in bones and teeth which provide the main framework and structural support for vital organs. Hydroxyapatite is present in a variety of crystallinities and also substituted with small amounts of ions such as carbonate and magnesium which overall contributes to the mineral phase of bone and teeth [1 , 2]. The first biodegradable ceramic discovered and used was particulate hydroxyapatite in Paster of Paris [3] (CaS04.2HzO) followed by the discovery of hydroxyapatite in 1920's [4]. Commercialization of hydroxyapatite occurred in the 1970's [5]. Despite the resorbability of hydroxyapatite it failed to provide a load bearing function; hence titanium alloy was used as the preferred material. Titanium has since been used extensively in orthopaedic implants for knee and hip prosthesis. Commercial hydroxyapatite implants are produced by plasma spraying hydroxyapatite onto titanium alloy, TisAL4 V which fulfils the load bearing function of the implant.

description: The reversing symmetry group is considered in the setting of symbolic dynamics. While this group is generally too big to be analysed in detail, there are interesting cases with some form of rigidity where one can determine all symmetries and reversing symmetries explicitly. They include Sturmian shifts as well as classic examples such as the Thue--Morse system with various generalisations or the Rudin--Shapiro system. We also look at generalisations of the reversing symmetry group to higher-dimensional shift spaces, then called the group of \emph{extended symmetries}. We develop their basic theory for faithful $\mathbb{Z}^{d}$-actions, and determine the extended symmetry group of the chair tiling shift, which can be described as a model set, and of Ledrappier's shift, which is an example of algebraic origin.

Determinants of Foreign Direct Investment Inflow to Ethiopia: Time Series Analysis
Creators: name: Solomon, Berhanemeskel
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: This thesis focuses on the determinants of foreign direct investment inflows to Ethiopia. In an attempt to attract Foreign Direct Investment (FDI), most countries have liberalized trade and attempted to create enabling environment in recent decades. Ethiopia, like many African countries, took some steps towards liberalizing trade and the macroeconomic regime as well as introducing some measures aimed at improving the FDI regulatory framework. This paper attempts to study the determinants of foreign direct investment inflows to Ethiopia over the period 1991-2017. The study gives an extensive account of the theoretical explanation of FDI as well as reviewing the FDI regulatory framework of the country over the study period. It also undertakes empirical analysis to establish the determining factors of FDI inflows to Ethiopia. Our findings show that macroeconomic instability and financial health, among others, have negative impact on FDI. These findings imply that financial health and macroeconomic stability are essential to attract FDI to Ethiopia.

Each robot regulates their responses to a different stimuli using a series of motivational states. Robots respond to requests once their motivation state is sufficiently high, which leads to a reduction in communication messages without significantly altering the outcome of the task. This allows team-mates to iteratively respond to each other's actions without directly influencing them. The position of a robot has always an error associated with the movement of the autonomous platform. These errors are measured from data derived from the experimentation and then calibrated with the novel laser interferometry based calibration methodology. Finally the proposed architecture is experimentally evaluated, thus testing the deliberative capabilities as well as the autonomous capabilities. The area coverage problem is chosen to test the architecture, and therefore four solutions to the problem were successfully established and experimentally tested. The Swarm Global Planner Methodology considerer the entire region when calculating the paths; the Divide and Conquer methodology divides the region into sub-regions, and subsequently distributes the workload among robots. The Biological Motivation Based methodology assigns tasks as they appear in the environment; the Controlled Distribution of Task methodology maintains a maximum number of robots working on each task. The experimental results showed the feasibility of the methodologies, the performance of the proposed architecture, and its versatility.

description: The semantic understanding of indoor 3D point cloud data is crucial for a range of subsequent applications, including indoor service robots, navigation systems, and digital twin engineering. Global features are crucial for achieving high-quality semantic and instance segmentation of indoor point clouds, as they provide essential long-range context information. To this end, we propose JSMNet, which combines a multi-layer network with a global feature self-attention module to jointly segment three-dimensional point cloud semantics and instances. To better express the characteristics of indoor targets, we have designed a multi-resolution feature adaptive fusion module that takes into account the differences in point cloud density caused by varying scanner distances from the target. Additionally, we propose a framework for joint semantic and instance segmentation by integrating semantic and instance features to achieve superior results. We conduct experiments on S3DIS, which is a large three-dimensional indoor point cloud dataset. Our proposed method is compared against other methods, and the results show that it outperforms existing methods in semantic and instance segmentation and provides better results in target local area segmentation. Specifically, our proposed method outperforms PointNet (Qi et al., 2017a) by 16.0% and 26.3% in terms of semantic segmentation mIoU in S3DIS (Area 5) and instance segmentation mPre, respectively. Additionally, it surpasses ASIS (Wang et al., 2019) by 6.0% and 4.6%, respectively, as well as JSPNet (Chen et al., 2022) by a margin of 3.3% for semantic segmentation mIoU and a slight improvement of 0.3% for instance segmentation mPre.

description: We present an HST/ACS weak gravitational lensing analysis of 13 massive high-redshift (z_median=0.88) galaxy clusters discovered in the South Pole Telescope (SPT) Sunyaev-Zel'dovich Survey. This study is part of a larger campaign that aims to robustly calibrate mass-observable scaling relations over a wide range in redshift to enable improved cosmological constraints from the SPT cluster sample. We introduce new strategies to ensure that systematics in the lensing analysis do not degrade constraints on cluster scaling relations significantly. First, we efficiently remove cluster members from the source sample by selecting very blue galaxies in V-I colour. Our estimate of the source redshift distribution is based on CANDELS data, where we carefully mimic the source selection criteria of the cluster fields. We apply a statistical correction for systematic photometric redshift errors as derived from Hubble Ultra Deep Field data and verified through spatial cross-correlations. We account for the impact of lensing magnification on the source redshift distribution, finding that this is particularly relevant for shallower surveys. Finally, we account for biases in the mass modelling caused by miscentring and uncertainties in the concentration-mass relation using simulations. In combination with temperature estimates from Chandra we constrain the normalisation of the mass-temperature scaling relation ln(E(z) M_500c/10^14 M_sun)=A+1.5 ln(kT/7.2keV) to A=1.81^{+0.24}_{-0.14}(stat.) +/- 0.09(sys.), consistent with self-similar redshift evolution when compared to lower redshift samples. Additionally, the lensing data constrain the average concentration of the clusters to c_200c=5.6^{+3.7}_{-1.8}.

Strength distribution and interactions of spinnable carbon nanotubes

description: Carbon nanotubes are innovative materials with high potential for applications in various industries. However, it is very hard to perform direct experimentation to characterise their mechanical behaviour due to their dimensional constraints. There is wide scatter in the re- ported mechanical strength of individual carbon nanotubes in the literature. Nevertheless, theoretically it is very well established that individually they are amongst the strongest materials so far. However, this strength has yet to transfer to macro scale structures such as carbon nanotube yarns. Individual nanotube has 100 GPa of strength with 1 TPa of modulus of elasticity. But nanotube yarns have reached so far 1.5 GPa of strength. To address the issue of this huge differences in strengths in different structural scales of same material, this thesis embarks on logical step wise investigation of strength distribution and interaction properties of spinnable carbon nanotubes. First, to address the scattering strength issue, this thesis undertake extensive experi- mental investigations utilizing the newly developed nano tensile stage to test the individ- ual carbon nanotubes under uni axial tensile load inside a Scanning Electron Microscope (SEM). It was shown that the strength distribution of spinnable nanotubes depends on the geometric features of the specimen such as the number of broken walls. It increase with the higher numbers of broken walls. However, the probability of getting all the walls of a nanotube broken without any external aid or modification is extremely low. To improve this probability and to enhance their strength, the effect of post synthesis treatments such as gamma irradiation technique is investigated. It is shown that the irradiation doses and environment have influence on strength of spinnable carbon nanotubes. The interaction among the carbon nanotubes has been investigated through macro scale peel tests. It was found that the orientation angle of the nanotubes with respect to each other has profound influence on their interaction characteristics. Simulation of this peeling mechanics revealed that nanotube interface undergo mode transformation which assisted the production of their macro scale constructs. As a result of the findings of this research, it would enhance the understanding of spinnable carbon nanotube characteristics.

description: This research work attempts to provide empirical evidence on Practices and challenges of interest free banking in Ethiopia with particular reference to Commercial banks currently offering interest free banking service. The study has employed descriptive research based on survey and the data are of cross sectional type. The study has used structured and semi structured questionnaire and interview. A total of 560 sample respondents were taken through multistage sampling. Of the total sample interest free banking customers and staffs of the bank constitutes 384 and 176 respectively. The data was analyzed using descriptive statistics of mean, frequency and percentage using SPSS version 20 Software. The findings showed that Interest free banking services have been benefiting banks, not only in terms of increasing customers and mobilizing deposits, but also they enjoyed greater profitability and FCY generation. The findings also show that currently knowledge of bankers and customers on Interest free banking and IFB products is low. Moreover a of customers' sampled show they are skeptic about Interest free banking window of commercial banks' ability manage their fund and Shari'ah compliance these windows. Furthermore, the compliance of theses windows merely depends on maintaining separate records and accounts which lacks shariah advisor and management commitment to ensure fully compliance with requirements for adopting interest free banking within the bank. In addition the result indicates lack of supervision by NBE, lack of confidence and trust of clients, lack of legal support from government, lack of qualified human resource, lack of cooperation among Islamic windows, lack of infrastructure suitable for Interest free banking operation, and doubt of clients identified by the practitioners as major challenges in the process of offering interest free banking services in Ethiopia. Accordingly, the study recommends that there should be vigorous public enlightenment programmes to create more awareness and to remove misconception and doubt among Muslim and non-Muslim; Shareholders, board of directors and the management of the bank should accept the concept and be cooperative with interest free banking window of the banking and establish a working Shari'ah supervisory board (SSB) for interest free banking operation and strictly comply with its guidance; The government of Ethiopia should take more proactive efforts to promote Interest free banking services with certain amendments laws and regulations and NBE should also establish a separate department for handling all issues relating to Interest-Free Banking and closely monitor and supervise the operation of interest banking windows of conventional banks.
