جنوب الجزيرة العربية - تاريخ

_ اكتشفت في موقع مليحة وسط امارة الشارقة أدلة كثيرة على التواصل بينها وبين مراكز تجارية عربية وأجنبية خلال فترة استيطانها بين أواخر القرن الثالث قبل الميلاد ومنتصف القرن الثالث الميلادي. أثبتت نتائج التنقيبات في مليحة منذ عام 1973 م وحتى الآن أنها ازدهرت في نفس فترة ازدهار الفاو والجرهاء، ونجران ومأرب، وتمنع وشبوة، والبتراء والبحرين، وغيرها، التي ترافق ازدهارها مع توسع تجارة البخور واللبان والتوابل، عبر الجزيرة العربية. ونظراً لموقع مليحة على الأطراف الشمالية الشرقية لصحراء الربع الخالي وعلى المسافة نفسها من الخليج العربي وبحرعُمان، فقد شاركت في الوضع الثقافي الذي ضم الفاو وسمد، وشمل ذلك اليمن بدون شك. واستفادت من المبادلات بين البحر الأبيض المتوسط وجنوبي شبه الجزيرة العربية والساحل الإيراني كما اتضح من بعض الموجودات أي أنها كانت على طريق هذه التجارة الهامة وشاركت فيها، وكانت محطتها في جنوب شرقي شبه الجزيرة العربية. وعلى امتداد هذا التواصل الذي شقت دروبه قوافل الجِمال، أو رفرفت وسط أمواجه أشرعة السفن كان إنسان مليحة يتلقى الأفكار والتأثيرات الثقافية، ويحمل معه بعض أنسامها، ويَسِمها بخصائص محلية أبقت كثيراً أو قليلاً من تلك التأثيرات. وفي هذا المقال نطلّ على أهم دلائل الروابط والصلات التي أقامها أهل مليحة مع مراكز جنوبي الجزيرة العربية التجارية وممالكها من خلال ما أفرزته المكتشفات الأثرية في الشارقة في العقود الخمسة الماضية.

description: We implement a Monte Carlo sampling strategy to extract helicity parton densities and their uncertainties from a reference set of longitudinally polarized scattering data, chosen to be that used in the DSSV14 global analysis. Instead of adopting the simplest possible functional forms for the helicity parton distributions and imposing certain restrictions on their parameter space in order to constrain them, we employ redundant, flexible parametrizations and fit them to a large number of Monte Carlo replicas of the existing data. The optimum fit and its uncertainty estimates are then assumed to be given by the statistical average of the obtained ensemble of replicas of helicity parton densities and their corresponding variance, respectively. We compare our results to those obtained by the traditional fitting approach and to the uncertainty estimates derived with the robust Lagrange multiplier method, finding good agreement. As a first application of our new set of replicas, we discuss the impact of the recent STAR dijet data in further constraining the elusive gluon helicity density through the reweighting method.

description: The role of step edge diffusion (SED) in epitaxial growth is investigated. To this end we revisit and extend a recently introduced simple cubic solid-on-solid model, which exhibits the formation and coarsening of pyramid or mound like structures. By comparing the limiting cases of absent, very fast (significant), and slow SED we demonstrate how the details of this process control both the shape of the emerging structures as well as the scaling behavior. We find a sharp transition from significant SED to intermediate values of SED, and a continuous one for vanishing SED. We argue that one should be able to control these features of the surface in experiments by variation of the flux and substrate temperature.

description: Cardiovascular diseases are one of the most common causes of death in the world. Prevention, knowledge of previous cases in the family, and early detection is the best strategy to reduce this fact. Different machine learning approaches to automatic diagnostic are being proposed to this task. As in most health problems, the imbalance between examples and classes is predominant in this problem and affects the performance of the automated solution. In this paper, we address the classification of heartbeats images in different cardiovascular diseases. We propose a two-dimensional Convolutional Neural Network for classification after using a InfoGAN architecture for generating synthetic images to unbalanced classes. We call this proposal Adversarial Oversampling and compare it with the classical oversampling methods as SMOTE, ADASYN, and RandomOversampling. The results show that the proposed approach improves the classifier performance for the minority classes without harming the performance in the balanced classes.

description: Various transcript elongation factors (TEFs) including modulators of RNA polymerase II (RNAPII) activity and histone chaperones tune the efficiency of transcription in the chromatin context. TEFs are involved in establishing gene expression patterns during growth and development in Arabidopsis, while little is known about the genomic distribution of the TEFs and the way they facilitate transcription. We have mapped the genome-wide occupancy of the elongation factors SPT4–SPT5, PAF1C and FACT, relative to that of elongating RNAPII phosphorylated at residues S2/S5 within the carboxyterminal domain. The distribution of SPT4–SPT5 along transcribed regions closely resembles that of RNAPII-S2P, while the occupancy of FACT and PAF1C is rather related to that of RNAPII-S5P. Under transcriptionally challenging heat stress conditions, mutant plants lacking the corresponding TEFs are differentially impaired in transcript synthesis. Strikingly, in plants deficient in PAF1C, defects in transcription across intron/exon borders are observed that are cumulative along transcribed regions. Upstream of transcriptional start sites, the presence of FACT correlates with nucleosomal occupancy. Under stress conditions FACT is particularly required for transcriptional upregulation and to promote RNAPII transcription through +1 nucleosomes. Thus, Arabidopsis TEFs are differently distributed along transcribed regions, and are distinctly required during transcript elongation especially upon transcriptional reprogramming.

description: Accurate and sensitive measurements of higher order cumulants open up new approaches to pion interferometry. It is now possible to test whether a given theoretical prediction can consistently match cumulants of both second and third order. Our consistency test utilizes a new technique combining theoretically predicted functions with experimentally determined weights in a quasi-Monte Carlo approach. Testing a general quantum statistics-based framework of Bose-Einstein correlations with this technique, we find that predictions for third order cumulants differ significantly from UA1 data. This discrepancy may point the way to more detailed dynamical information.

description: Iron oxides are among the most abundant compounds on Earth and have consequently been studied and used extensively in industrial processes. Despite these efforts, concrete understanding of some of their surface phase structures has remained elusive, in particular the oxidized $α-Fe_2O_3(0001)$ hematite surface. We detail an optimized recipe to produce this phase over the entire hematite surface and study the geometrical parameters and composition of its complex structure by means of atomically resolved microscopy, electron diffraction and surface-sensitive spectroscopies. We conclude that the oxidized $α-Fe_2O_3(0001)$ surface is terminated by a two-dimensional iron oxide with structure, lattice parameters, and orientation different from the bulk substrate. Using total-energy density functional theory for simulation of a large-scale atomic model, we identify the structure of the surface layer as antiferromagnetic, conductive $1T-FeO_2$ attached on half-metal terminated bulk. The model succeeds in reproducing the characteristic modulations observed in the atomically resolved images and electron diffraction patterns.

description: We calculate the incoherent resonant and non-resonant scattering production of sterile neutrinos in the early universe. We find ranges of sterile neutrino masses, vacuum mixing angles, and initial lepton numbers which allow these species to constitute viable hot, warm, and cold dark matter (HDM, WDM, CDM) candidates which meet observational constraints. The constraints considered here include energy loss in core collapse supernovae, energy density limits at big bang nucleosynthesis, and those stemming from sterile neutrino decay: limits from observed cosmic microwave background anisotropies, diffuse extragalactic background radiation, and Li-6/D overproduction. Our calculations explicitly include matter effects, both effective mixing angle suppression and enhancement (MSW resonance), as well as quantum damping. We for the first time properly include all finite temperature effects, dilution resulting from the annihilation or disappearance of relativistic degrees of freedom, and the scattering-rate-enhancing effects of particle-antiparticle pairs (muons, tauons, quarks) at high temperature in the early universe.

description: A theory of scattering by charged dislocation lines in a two-dimensional electron gas (2DEG) is developed. The theory is directed towards understanding transport in AlGaN/GaN high-electron-mobility transistors (HEMT), which have a large number of line dislocations piercing through the 2DEG. The scattering time due to dislocations is derived for a 2DEG in closed form. This work identifies dislocation scattering as a mobility-limiting scattering mechanism in 2DEGs with high dislocation densities. The insensitivity of the 2DEG (as compared to bulk) to dislocation scattering is explained by the theory.

description: Additional file 5: Figure S5 Mean plasma and tumor concentrations of APG-115 in MH-22A tumor bearing mice after treatment. Mice bearing MH-22A tumor were treated with vehicle, APG-115, anti-PD-1 alone or their combination. Four hours after the drug administration on day eight, the plasma and tumor concentrations of APG-115 were analyzed by quantitative liquid chromatography mass spectrometry (LC/MS/MS). Briefly, quantitative LC/MS/MS analysis was conducted using an Exion HPLC system (AB Sciex) coupled to an API 5500 mass spectrometer (AB Sciex) equipped with an API electrospray ionization source. The Phenomenex Titank phenyl-Hexyl column (50 mm × 2.1 mm, 5 μm particle size) was used to achieved HPLC separation. The injection volume was 2 μL and the flow rate was kept constantly at 0.5 mL/min. Chromatography was performed with mobile phase A, acetonitrile: water: formic (5:95:0.1, in volume) and B, acetonitrile: water: formic (95:5:0.1, in volume). The mass spectrometer was operated at ESI positive ion mode for APG-115. The results were presented as dot plots with each dot representing a sample.

description: We discuss baryon production in the nucleon fragmentation region in deep inelastic scattering. The dependence of the nucleon spectra on Bjorken-$x$ is evaluated within the parton model and in QCD, and ways to look for the break-down of the DGLAP approximation via baryon production are suggested. We argue also that the leading neutron production in these small $x$ processes is rather insensitive to the pion parton densities of the nucleon.

description: We study interference patterns in the $ϕ\to(γa_0+π^0ρ)\toγπη$ and $ϕ\to(γf_0+π^0ρ)\toγπ^0π^0$ reactions. Taking into account the interference, we fit the experimental data and show that the background reaction does not distort the $π^0η$ spectrum in the decay $ϕ\toγπη$ everywhere over the energy region and does not distort the $π^0π^0$ spectrum in the decay $ϕ\toγπ^0π^0$ in the wide region of the $π^0π^0$ system invariant mass, $m_{ππ}>670$ MeV, or when the photon energy is less than 300 MeV. We discuss the details of the scalar meson production in the radiative decays and note that there are reasonable arguments in favor of the one-loop mechanism $ϕ\to K^+K^-\toγa_0$ and $ϕ\to K^+K^-\toγf_0$. We discuss also distinctions between the four-quark, molecular, and two-quark models and argue that the Novosibirsk data give evidence in favor of the four-quark nature of the scalar $a_0(980)$ and $f_0(980)$ mesons.

title: The influence of measurement density on micro-instability testing
Creators: name: Daling, Nika
Publisher: name: Student Undergraduate Research E-journal!

description: Protection from water flooding by dikes is an important issue in the Netherlands. Therefore dikes have to be regularly tested for possible failure, for example caused by micro-instability. Micro-instability occurs in the upper layer of the dike, due to water flowing through it. The goal of this research was to determine the influence of the measurement density on safety assessment of river dikes for micro-instability and in addition to give a confidence interval for these assessments. This paper shows that uncertainty in cover layer thickness has the largest effect on the reliability of dike safety assessment in relation to micro-instability.

description: Motivated by the important role of the normalized second order coherence function, often called $g^{(2)}$, in the field of quantum optics, we propose a method to determine magnon coherence in solid-state devices. Namely, we show that the cross-correlations of pure spin-currents injected by a ferromagnet into two metal leads, normalized by their dc value, replicate the behavior of $g^{(2)}$ when magnons are driven far from equilibrium. We consider two scenarios: driving by ferromagnetic resonance, which leads to the coherent occupation of a single mode, and driving by heating of the magnons, which leads to an excess of incoherent magnons. We find an enhanced normalized cross-correlation in the latter case, thereby demonstrating bunching of nonequilibrium thermal magnons due to their bosonic statistics. Our results contribute to the burgeoning field of quantum magnonics, which seeks to explore and exploit the quantum nature of magnons.

description: The Upper Citarum River Basin is a heavily polluted catchment on West Java, Indonesia. Policy makers and scientist show increasing interest for the issue, but there is no recent scientific study that gives an overview of the current state of the river basin. In this paper, the six drivers of the water quality problem are described by system analysis, tracing them back to weak social and governmental institutions. Stakeholder analysis reveals a strong mismatch between responsibilities, authorities and resources among monitoring stakeholders. Data analysis shows that the industry is the largest polluter of the basin, followed by pollutants from domestic origin.

description: We propose energy bandpass filtering employed using the idea of anti-reflection heterostructures as a means to reduce the energy requirements of a superlattice phase change memory based on GeTe and Sb$_{2}$Te$_{3}$ heterostructures. Different configurations of GeTe/Sb$_{2}$Te$_{3}$ superlattices are studied using the non-equilibrium Green's function approach. Our electronic transport simulations calculate the coupling parameter for the high resistance covalent state, to $97 \%$ that of the stable low resistance resonant state, maintaining the ON/OFF ratio of 100 for a reliable read operation. By examining various configurations of the superlattice structures we conclude that the inclusion of anti-reflection units on both sides of the superlattice increases the overall ON/OFF ratio by an order of magnitude which can further help in scaling down of the memory device. It is also observed that the device with such anti-reflection units exhibits 32$\%$ lesser RESET voltage than the most common PCM superlattice configurations and 27$\%$ in the presence of elastic dephasing. Moreover, we also find that the ON/OFF ratios in these devices are also resilient to the variations in the periodicity of the superlattice.

description: Het drooggedrag van watergedragen verven wordt in grote mate bepaald door de vervormbaarheid van de microscopisch kleine deeltjes waaruit ze bestaan. Om het effect van deze vervormbaarheid op het droogproces van een suspensie druppel te testen, synthetiseren wij gecrosslinkte rubber nanodeeltjes in water. De crosslinker voorkomt samenvloeiing van de deeltjes. De fenomenen die we observeren bij het drogen van zo’n druppeltje, invasie van lucht, capillaire deformatie, rimpelingen en breukvorming, blijken te veranderen rond één algemene transitiewaarde voor de hardheid van de deeltjes. Het geheel komt goed overeen met onze theoretische voorspellingen voor het droogproces. Dit onderzoek is ook gepubliceerd in Soft Matter (Kooij et al., Soft Matter 12, 2858–2867 (2016)).

description: Reversible field-induced phase transitions define antiferroelectric perovskite oxides and lay the foundation for high-energy storage density materials, required for future green technologies. However, promising new antiferroelectrics are hampered by transition´s irreversibility and low electrical resistivity. Here, we demonstrate an approach to overcome these problems by adjusting the local structure and defect chemistry, delivering NaNbO₃-based antiferroelectrics with well-defined double polarization loops. The attending reversible phase transition and structural changes at different length scales are probed by in situ high-energy X-ray diffraction, total scattering, transmission electron microcopy, and nuclear magnetic resonance spectroscopy. We show that the energy-storage density of the antiferroelectric compositions can be increased by an order of magnitude, while increasing the chemical disorder transforms the material to a relaxor state with a high energy efficiency of 90%. The results provide guidelines for efficient design of (anti-)ferroelectrics and open the way for the development of new material systems for a sustainable future.

description: We report two surprising results regarding the nature of the spatial broken symmetries in the two-dimensional (2D), quarter-filled band with strong electron-electron interactions. First, in direct contradiction to the predictions of one-electron theory, we find a coexisting ``bond-order and charge density wave'' (BCDW) insulating ground state in the 2D rectangular lattice for all anisotropies, including the isotropic limit. Second, we find that the BCDW further coexists with a spin-density wave (SDW) in the range of large anisotropy. Further, in contrast to the interacting half-filled band, in the interacting quarter-filled band there are two transitions: first, a similar singlet-to-AFM/SDW transition for large anisotropy and second, an AFM/SDW-to-singlet transition at smaller anisotropy. We discuss how these theoretical results apply to the insulating states that are proximate to the superconducting states of 2:1 cationic charge-transfer solids (CTS). An important consequence of this work is the suggestion that organic superconductivity is related to the proximate Coulomb-induced BCDW, with the SDW that coexists for large anisotropies being also a consequence of the BCDW, rather than the driver of superconductivity.

description: The insulating state of matter is characterized by the excitation spectrum, but also by qualitative features of the electronic ground state. The insulating ground wavefunction in fact: (i) sustains macroscopic polarization, and (ii) is localized. We give a sharp definition of the latter concept, and we show how the two basic features stem from essentially the same formalism. Our approach to localization is exemplified by means of a two--band Hubbard model in one dimension. In the noninteracting limit the wavefunction localization is measured by the spread of the Wannier orbitals.

description: We present an efficient scheme for the generation and control of a degenerate four-wave mixing (FWM) signal in a N-type inhomogeneously broadened 85Rb atomic system. We observe the propagation dynamics of the generated FWM signal along with the probe pulse under the condition of Electromagnetically Induced Transparency. The FWM signal clones the temporal shape of the probe pulse and travels through the medium without changing its shape and intensity. We have also shown that a time dependent control field permits the storage and retrieval of these optical signals without losing their identity. This work allows us to generate, control, store and retrieve FWM signal of any arbirary shape.

description: Maximizing the minimum rate for a full-duplex multiple-input multiple-output (MIMO) wireless network encompassing two sources and a two-way (TW) relay operating in a two hop manner is investigated. To improve the overall performance, using a zero-forcing approach at the relay to suppress the residual self-interference arising from full-duplex (FD) operation, the underlying max-min problem is cast as an optimization problem which is non-convex. To circumvent this issue, semidefinite relaxation technique is employed, leading to upper and lower bound solutions for the optimization problem. Numerical results verify that the upper and lower bound solutions closely follow each other, showing that the proposed approach results in a close-to-optimal solution. In addition, the impact of residual self-interference upon the overall performance of the network in terms of the minimum rate is illustrated by numerical results, and for low residual self-interference scenarios the superiority of the proposed method compared to an analogous half-duplex (HD) counterpart is shown.

description: We propose a supergravity model that contains elements recently shown to arise in the strongly-coupled limit of the $E_8\times E_8$ heterotic string (M-theory), including a no-scale--like Kähler potential, the identification of the string scale with the gauge coupling unification scale, and the onset of supersymmetry breaking at an intermediate scale determined by the size of the eleventh dimension of M-theory. We also study the phenomenological consequences of such scenario, which include a rather constrained sparticle spectrum within the reach of present-generation particle accelerators.

title: Structural characterization and activation of nature’s fuels of life
Creators: name: Van Outersterp, Rianne
Publisher: name: Student Undergraduate Research E-journal!
Year: 2016

description: Hydrolysis of nucleotide triphosphates (NTPs) is known to drive highly important cellular processes. Of these NTPs, adenine triphosphate (ATP) is mainly studied as it is concerned to be the central fuel of living cells. Gas-phase studies have been performed to elucidate the conformational preference of NTPs focusing on the dependence of the nucleobase and extent of deprotonation. Therefore, a combination of infrared (IR) spectroscopy and mass spectrometry has been applied to ATP, CTP and GTP. IR action spectroscopy and supporting theoretical studies showed that the attached nucleobase has little influence on the three-dimensional structure of the phosphate tail. The favorable deprotonation sites of the singly and doubly deprotonated NTPs have been assigned. This can lead to a better explanation of the behavior and selection of NTPs in living cells.

Establishing TVET Applied Research, Production and Extension centers in National Polytechnics can Spur Industrialization

description: According to Applied Research, applied research aims at finding a solution for an immediate problem facing a society, or an industrial/business organization and is considered to be a non-systematic inquiry usually launched by a company, agency or an individual in order to address a specific problem. While organizations in Kenya aspire to industrialize, lack of clarity on the appropriate strategy to go about it can stand in their way. Kenya Vision 2030 proposes application of science, technology and innovation to up the productivity and efficiency levels across the economic, social and political pillars. It therefore underscores the crucial role played by research and development (R&D) in spurring economic development. A survey across TVET institutions in Kenya shows that important industrial skills are offered in training but with one missing link: a coordinated central linkage between the institutions and industrial players as a way of enhancing the utilization of the skills to enhance productivity for mutual benefit. A grounded theory and discourse analysis of the survey confirms attempts by the institutions and line directorates to make this a reality.  By a case study with a peer higher education institution, this research concludes that establishing Applied Research, Production and Extension centers is the best way to go for mutual benefits between the TVET institutions, industrial players and the trainees in terms of quality of labor via the trainees; industrial products innovation and development and entrepreneurial industrialization. Important areas for industrialization can be tapped and developed in partnership with industrial players, external research partners, research & development and innovation sponsors, and relevant government agencies.

Electronic Fine Structure in the Electron-Hole Plasma in SrB6

description: Electron-hole mixing-induced fine structure in alkaline earth hexaborides leads to lower energy (temperature) scales, and thus stronger tendency toward an excitonic instability, than in their doped counterparts (viz. Ca(1-x)La(x)B(6), x=0.005), which are high Curie temperature, small moment ferromagnets. Comparison of Fermi surfaces and spectral distributions with de Haas - van Alphen (dHvA), optical, transport, and tunneling data indicates that SrB6 remains a fermionic semimetal down to (at least) 5 K, rather than forming an excitonic condensate. For the doped system the Curie temperature is higher than the degeneracy temperature.

description: Data peeking, quitting data collection early or adding more participants at the end, offers the advantage of saving time and money. However, performing an interim analysis without correction leads to a Type-I error inflation. Using alpha spending function could be used to solve this problem. In this paper, we simulated the effects of interim analysis with and without an alpha spending function on type-I error, power and expected sample size. We also offer a Bayesian perspective to interim analysis. In the last part, we discuss the use of interim analysis in psychological research using a qualitative approach.

Communicating Unknown Words in Machine Translation
Creators: name: Waibel, Alex
name: Vogel, Stephan
name: Eck, Matthias
Publisher: name: Association for Computational Linguistics (ACL)
Year: 2008

description: A new approach to handle unknown words in machine translation is presented. The basic idea is to find definitions for the unknown words on the source language side and translate those definitions instead. Only monolingual resources are required, which generally offer a broader coverage than bilingual resources and are available for a large number of languages. In order to use this in a machine translation system definitions are extracted automatically from online dictionaries and encyclopedias. The translated definition is then inserted and clearly marked in the original hypothesis. This is shown to lead to significant improvements in (subjective) translation quality.

description: We tackle \ac{NED} by comparing entities in short sentences with \wikidata{} graphs. Creating a context vector from graphs through deep learning is a challenging problem that has never been applied to \ac{NED}. Our main contribution is to present an experimental study of recent neural techniques, as well as a discussion about which graph features are most important for the disambiguation task. In addition, a new dataset (\wikidatadisamb{}) is created to allow a clean and scalable evaluation of \ac{NED} with \wikidata{} entries, and to be used as a reference in future research. In the end our results show that a \ac{Bi-LSTM} encoding of the graph triplets performs best, improving upon the baseline models and scoring an \rm{F1} value of $91.6\%$ on the \wikidatadisamb{} test set
Density Waves and Jamming Transition in Cellular Automaton Models for Traffic Flow

description: In this paper computer simulation results of higher order density correlation for cellular automaton models of traffic flow are presented. The examinations show the jamming transition as a function of both the density and the magnitude of noise and allow to calculate the velocity of upstream moving jams. This velocity is independent of the density and decreases with growing noise. The point of maximum flow in the fundamental diagram determines its value. For that it is not necessary to define explicitly jams in the language of the selected model, but only based upon the well defined characteristic density profiles along the line.
