On Outage Probability and Diversity-Multiplexing Tradeoff in MIMO Relay Channels

description: Fading MIMO relay channels are studied analytically, when the source and destination are equipped with multiple antennas and the relays have a single one. Compact closed-form expressions are obtained for the outage probability under i.i.d. and correlated Rayleigh-fading links. Low-outage approximations are derived, which reveal a number of insights, including the impact of correlation, of the number of antennas, of relay noise and of relaying protocol. The effect of correlation is shown to be negligible, unless the channel becomes almost fully correlated. The SNR loss of relay fading channels compared to the AWGN channel is quantified. The SNR-asymptotic diversity-multiplexing tradeoff (DMT) is obtained for a broad class of fading distributions, including, as special cases, Rayleigh, Rice, Nakagami, Weibull, which may be non-identical, spatially correlated and/or non-zero mean. The DMT is shown to depend not on a particular fading distribution, but rather on its polynomial behavior near zero, and is the same for the simple "amplify-and-forward" protocol and more complicated "decode-and-forward" one with capacity achieving codes, i.e. the full processing capability at the relay does not help to improve the DMT. There is however a significant difference between the SNR-asymptotic DMT and the finite-SNR outage performance: while the former is not improved by using an extra antenna on either side, the latter can be significantly improved and, in particular, an extra antenna can be traded-off for a full processing capability at the relay. The results are extended to the multi-relay channels with selection relaying and typical outage events are identified.

description: Background:  Iron folate supplementation in pregnant women is needed to address two
main problems: maternal anemia and neural tube closure defects .World health
organization recommend standard dose of 60 mg iron + 400 μg folic acid daily for six
months for all pregnant women. According to Mini Ethiopian Demographic Health
Survey 2014 only 34% took iron tablets during their last pregnancy this did not show the
level of adherence. Therefore, this study aims to assess the level of adherence to iron
folate supplement and factors affecting the level of adherence among pregnant women in
the study area. And the study will serve as a base line data for further study.
Objective: To assess level of adherence to Iron Folate Supplementation and associated
factors among pregnant women in Burji woreda Segen area peoples zone 2017.
Methods and material: A community based cross sectional study was conducted among
pregnant women in Burji woreda, from December to May2017. Simple random sampling
was used to select 8 kebeles from 26 kebele. Single Population proportion formula was
used to estimate the sample size of 317 pregnant. The data was coded, entered, in to
Epi.info version 3.5.1, bivariate and multivariable analysis was conducted by SPSS
version 20.And the result was presented using  proportions, mean and median, and
Significance was declared by using p value of <0.05 and at 95% confidence interval.
Result:  About half  (51.4%) pregnant  women were adhered  to iron folic acid
supplementation  based on pill counting.  Women’s  education,  (AOR=2.10(1.0, 4.4),
frequency of ANC visit (AOR=2.2, (1.16, 4.06), Starting month of ANC
(AOR=3.7(1.056, 13.164)  respectively were significantly associated with  IFA  adherent
among pregnant in study area.
Conclusion and Recommendation: About half of pregnant women were not adhere with
iron folic acid supplementation despite WHO  recommendation. The  associated  factors
identified not to adhere  to IFA supplementation during pregnancy were forgetfulness,
followed by fear of sideefects, and inadequate supplements in the facility.
 Encouraging women to consume IFA tablets daily in between meals, and to put the IFA
tablets where it was seen easily, reduce the reasons of non adherent of IFA supplement.

description: The quasiparticle band structure and optical properties of single-walled zigzag and armchair SiC nanotubes (SiC-NTs) as well as single SiC sheet are investigated by ab initio many-body calculations using the GW and the GW plus Bethe-Salpeter equation (GW+BSE) approaches, respectively. Significant GW quasiparticle corrections of more than 1.0 eV to the Kohn-Sham band gaps from the local density approximation (LDA) calculations are found. The GW self-energy corrections transform the SiC sheet from a indirect LDA band gap to a direct band gap material. Furthermore, the quasiparticle band gaps of SiC-NTs with different chiralities behave very differently as a function of tube diameter, and this can be attributed to the difference in the curvature-induced orbital rehybridization between the different chiral nanotubes. The calculated optical absorption spectra are dominated by discrete exciton peaks due to exciton states with large binding energy up to 2.0 eV in the SiC sheet and SiC-NTs. The formation of strongly bound excitons is attributed to the enhanced electron-hole interaction in these low dimensional systems. Remarkably, the excited electron amplitude of the exciton wavefunction is found to peak on the Si atoms near the hole position (which is on the C site) in the zigzag SiC-NTs, indicating a charge transfer from an anion (hole) to its neighboring cations by photoexcitation. In contrast, this pronounced peak structure disappear in the exciton wavefunction in the armchair SiC-NTs. Furthermore, in the armchair SiC-NTs, the bound exciton wavefunctions are more localized and also strongly cylindrically asymmetric.

description: A versatile stroboscopic technique based on active phase-locking of a surface acoustic wave to picosecond laser pulses is used to monitor dynamic acoustoelectric effects. Time-integrated multi-channel detection is applied to probe the modulation of the emission of a quantum well for different frequencies of the surface acoustic wave. For quantum posts we resolve dynamically controlled generation of neutral and charged excitons and preferential injection of holes into localized states within the nanostructure.

description: Geometrical Volume-of-Fluid (VoF) methods mainly support structured meshes, and only a small number of contributions in the scientific literature report results with unstructured meshes and three spatial dimensions. Unstructured meshes are traditionally used for handling geometrically complex solution domains that are prevalent when simulating problems of industrial relevance. However, three-dimensional geometrical operations are significantly more complex than their two-dimensional counterparts, which is confirmed by the ratio of publications with three-dimensional results on unstructured meshes to publications with two-dimensional results or support for structured meshes. Additionally, unstructured meshes present challenges in serial and parallel computational efficiency, accuracy, implementation complexity, and robustness. Ongoing research is still very active, focusing on different issues: interface positioning in general polyhedra, estimation of interface normal vectors, advection accuracy, and parallel and serial computational efficiency.
 This survey tries to give a complete and critical overview of classical, as well as contemporary geometrical VOF methods with concise explanations of the underlying ideas and sub-algorithms, focusing primarily on unstructured meshes and three dimensional calculations. Reviewed methods are listed in historical order and compared in terms of accuracy and computational efficiency.

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: If the Einstein-Hilbert action ${\cal L}_{\rm EH}\propto R$ is re-expressed in Riemann-Cartan spacetime using the gauge fields of translations, the vierbein field $h^α_μ$, and the gauge field of local Lorentz transformations, the spin connection $A_{μα}{}^ β$, there exists a new gauge symmetry which permits reshuffling the torsion, partially or totally, into the Cartan curvature term of the Einstein tensor, and back, via a {\em new multivalued gauge transformation\/}. Torsion can be chosen at will by an arbitrary gauge fixing functional. There exist many equivalent ways of specifing the theory, for instance Einstein's traditional way where ${\cal L}_{\rm EH}$ is expressed completely in terms of the metric $g_{μν}=h^ α{}_μh_ α{}_ ν$, and the torsion is zero, or Einstein's teleparallel formulation, where ${\cal L}_{\rm EH}$ is expressed in terms of the torsion tensor, or an infinity of intermediate ways. As far as the gravitational field in the far-zone of a celestial object is concerned, matter composed of spinning particles can be replaced by matter with only orbital angular momentum, without changing the long-distance forces, no matter which of the various new gauge representations is used.

Gain assisted nanocomposite multilayers with near zero permittivity modulus at visible frequencies

description: We have fabricated a layered nano-composite by alternating metal and gain medium layers, the gain dielectric consisting of a polymer incorporating optically pumped dye molecules. Exploiting an improved version of the effective medium theory, we have chosen the layers thicknesses for achieving a very small value of the real part of the permittivity epsilon_\| (parallel to the layers plane) at a prescribed visible wavelength. From standard reflection-transmission experiments on the optically pumped sample we show that, at a visible wavelength, both the real and the imaginary parts of the permittivity epsilon_\ attain very small values and we measure | ε_\| | = 0.04 at lambda = 604 nm, amounting to a 21.5-percent decrease of the minimum | ε_\| | in the absence of optical pumping. Our investigation thus proves that a medium with a dielectric permittivity with very small modulus, a key condition which should provide efficient subwavelength optical steering, can be actually synthesized.

description: Star formation is regulated through a variety of feedback processes. In this study, we treat feedback by X-rays and discuss its implications. Our aim is to investigate whether star formation is significantly affected when a star forming cloud resides in the vicinity of a strong X-ray source. We perform an Eulerian grid simulation with embedded Lagrangian sink particles of a collapsing molecular cloud near a massive, 10^7 M_o black hole. The chemical and thermal changes caused by radiation are incorporated into the FLASH code. When there is strong X-ray feedback the star forming cloud fragments into larger clumps whereby fewer but more massive protostellar cores are formed. Competitive accretion has a strong impact on the mass function and a near-flat, non-Salpeter IMF results.

Building on Treacherous Ground: Sense-of-Purpose Research and Demarcating Problematic Purposes

Year: 2010

description: Developmental psychologist Damon’s (Damon, Menon, & Cotton Bronk, 2003) ongoing research program on youth purpose may have important practical implications for education. However, in the course of the development of this research, two fundamental conceptual questions have not yet been resolved satisfactorily: (a) How should “sense of purpose” be defined? and (b) How can one distinguish between noble and ignoble purposes? A careful examination of Damon et al.’s (2003) approach to these two questions is conducted, and some significant shortcomings in the analysis are pointed out. Specifically, Damon et al.’s definition of purpose is shown to be idiosyncratic, and some defects are pointed out in the criteria offered to differentiate between noble and ignoble purposes. In conclusion, an alternative approach to demarcating purpose is offered that relies on Erikson’s (1968) concept of totalized identity.

description: We consider the generation of electric currents in the solar chromosphere where the ionization level is typically low. We show that ambient electrons become magnetized even for weak magnetic fields (30 G); that is, their gyrofrequency becomes larger than the collision frequency while ion motions continue to be dominated by ion-neutral collisions. Under such conditions, ions are dragged by neutrals, and the magnetic field acts as if it is frozen-in to the dynamics of the neutral gas. However, magnetized electrons drift under the action of the electric and magnetic fields induced in the reference frame of ions moving with the neutral gas. We find that this relative motion of electrons and ions results in the generation of quite intense electric currents. The dissipation of these currents leads to resistive electron heating and efficient gas ionization. Ionization by electron-neutral impact does not alter the dynamics of the heavy particles; thus, the gas turbulent motions continue even when the plasma becomes fully ionized, and resistive dissipation continues to heat electrons and ions. This heating process is so efficient that it can result in typical temperature increases with altitude as large as 0.1-0.3 eV/km. We conclude that this process can play a major role in the heating of the chromosphere and corona

A novel photovoltaic device for improvements in solar energy collection

description: Governments around the world are striving to develop clean energy solutions to lessen their impact on the environment while addressing the growing need for energy generation. Solar technology has emerged as a major contender and will undoubtedly play a role in this endeavour. However, solar technology has been hampered by its fundamental challenge of cost versus performance. The proposed work recognizes this challenge and introduces a corner-cube-cell capable of being uniformly arrayed for scalability. It is shown that the corner-cube-cell facilitates low-cost implementations, due to its compatibility with standard silicon solar cells, and enables improved performance. Performance improvements shown in this work exhibit an increase in generated electrical power density of up to 3.80% at noon for an 8.29% increase in generated electrical energy density by the end of the day. This improvement comes about due to the geometry of the corner-cube-cell, which captures internal reflections and can exploit multi-channel maximum power point tracking. The corner-cube-cell also shows substantial improvements in generated electrical energy density during sun-rise and sun-set due to its protrusion out of the two-dimensional (horizontal) plane. These performance improvements result in a 6.10% increase in semi-annual generated electrical energy density over a conventional flat-lying solar cell. The introduced technology has strong prospects for realizing low-cost and high-performance solar power system implementations.

description: With the KOSMA 3-m telescope, 54 Herbig Ae/Be stars were surveyed in CO and $^{13}$CO emission lines. The properties of the stars and their circumstellar environments are studied by fitting the SEDs. The mean line width of $^{13}$CO (2-1) lines of this sample is 1.87 km s$^{-1}$. The average column density of H$_{2}$ is found to be $4.9\times10^{21}$ cm$^{-2}$ for the stars younger than $10^{6}$ yr, while drops to $2.5\times10^{21}$ cm$^{-2}$ for those older than $10^{6}$ yr. No significant difference is found among the SEDs of Herbig Ae stars and Herbig Be stars at the same age. The infrared excess decreases with age. The envelope masses and the envelope accretion rates decease with age after $10^{5}$ yr. The average disk mass of the sample is $3.3\times10^{-2} M_{\sun}$. The disk accretion rate decreases more slowly than the envelope accretion rate. A strong correlation between the CO line intensity and the envelope mass is found.

Spectroscopy as a test of Coulomb's law - A probe of the hidden sector

description: High precision spectroscopy can provide a sensitive tool to test Coulomb's law on atomic length scales. This can then be used to constrain particles such as extra "hidden" photons or minicharged particles that are predicted in many extensions of the standard model, and which cause small deviations from Coulomb's law. In this paper we use a variety of transitions in atomic hydrogen, hydrogenic ions, and exotic atoms to probe Coulomb's law. This extends the region of pure Coulomb's law tests to larger masses. For hidden photons and minicharged particles this region is already tested by other astrophysical and laboratory probes. However, future tests of true muonium and muonic atoms are likely to probe new parameter space and therefore have good discovery potential for new physics. Finally, we investigate whether the discrepancy between the theoretical calculation of the 2s_{1/2}^{F=1} - 2p_{3/2}^{F=2} transition in muonic hydrogen and its recent experimental measurement at PSI can be explained by the existence of a hidden photon. This explanation is ruled out by measurements of the Lamb shift in ordinary hydrogen.

Special Education in First Nations Schools in Canada: Policies of Cost Containment
Creators: name: Phillips, Ron

description: The education of First Nations students in Canada on reserve is the legal responsibility of the federal government. This article reviews and critiques the federal government’s past and current special education policies and practices in regard to First Nations schools throughout Canada. The author has found that rather than establishing a comprehensive special education system for First Nations schools, the federal government has focused on limiting funding, services, and development. Four themes emerge from this review: (a) lack of willingness on the part of the federal government to honor constitutional obligations and responsibilities in special education to First Nations; (b) focus of providing provincial level of special education services resulted in little consultation with First Nations; (c) limited funding, and (d) lack of respect for First Nations expertise.

description: Encouraging student engagement is a key aim in any educational setting, and allowing students the freedom to pursue their own methods of solving problems through independent experimentation has been shown to markedly improve this. In many contexts, however, allowing students this flexibility in their learning is hampered by constraints of the material itself, such as in the electronics laboratory, where expensive and bulky equipment confines the learning environment to the laboratory room. Finding ourselves in the position of teaching one such laboratory course at the undergraduate level, we sought to encourage students to learn through independent investigation and the pursuit of personal projects, by providing a more flexible and inquiry-based learning environment and allowing them to take their measurement equipment -- and their learning -- beyond the laboratory itself. We present this project as a case of design both for and by students, with the lead designer undertaking the project after attending the course in question, and pursuing its development as a foundational step in their graduate career. We discuss the challenges and opportunities we encountered over the course of the design and development process, and the eventual key output of the project: a portable, low-cost, integrated electronics experimentation platform called the Winterlab board.

Candidate X-ray-Emitting OB Stars in the Carina Nebula Identified Via Infrared Spectral Energy Distributions

description: We report the results of a new survey of massive, OB stars throughout the Carina Nebula using the X-ray point source catalog provided by the Chandra Carina Complex Project (CCCP) in conjunction with infrared (IR) photometry from the Two Micron All-Sky Survey and the Spitzer Space Telescope Vela--Carina survey. Mid-IR photometry is relatively unaffected by extinction, hence it provides strong constraints on the luminosities of OB stars, assuming that their association with the Carina Nebula, and hence their distance, is confirmed. We fit model stellar atmospheres to the optical (UBV) and IR spectral energy distributions (SEDs) of 182 OB stars with known spectral types and measure the bolometric luminosity and extinction for each star. We find that the extinction law measured toward the OB stars has two components: Av=1--1.5 mag produced by foreground dust with a ratio of total-to-selective absorption Rv=3.1 plus a contribution from local dust with Rv>4.0 in the Carina molecular clouds that increases as Av increases. Using X-ray emission as a strong indicator of association with Carina, we identify 94 candidate OB stars with Lbol\geq10^4 Lsun by fitting their IR SEDs. If the candidate OB stars are eventually confirmed by follow-up spectroscopic observations, the number of cataloged OB stars in the Carina Nebula will increase by ~50%. Correcting for incompleteness due to OB stars falling below the Lbol cutoff or the CCCP detection limit, these results potentially double the size of the young massive stellar population.

Navigating family caregiving for dementia : the joint actions and projects of family members
Creators: name: Silva, Vanessa
Publisher: name: University of British Columbia
Year: 2019

description: As the “baby boom” generation ages and the population shifts over the next two decades there will be an unparalleled number of individuals in need of care and a significant gap in resources to meet the demand. With this shift, family members, though often unequipped and lacking in resources, are expected to shoulder the financial, medical, and other care needs of the aging population (Barnett, 2015). Though one individual often serves as the main caregiver, all family members can be impacted and experience stress due to the complex caregiving process. This study explored the joint goal-directed processes that occur in the caregiving process for a family member with dementia. The research question that guided the study was, “What are the goal-directed actions and projects that family members construct, express and participate in together, relevant to the caregiving process for a family member with dementia?” The method used to explore this research question was the action project method that examines the internal thoughts and feelings, manifest behaviours and social meaning behind joint actions. Three family dyads (six individuals) who are involved in family caregiving for an individual with dementia participated in a joint conversation and self-confrontation interview. The study was examined from a multicase perspective following in-depth analysis of each case using the action project method. Qualitative analysis revealed that family members engaged in joint goal-directed actions that facilitated caregiving projects for the three participating families. Although there were processes unique to each family, common processes amongst the three families included relative unwillingness to vocalize internal thoughts and feelings, a focus on the primary caregiver, having different perspectives on caregiving, prioritization of physical needs of the caregiver or care receiver, and grieving the loss of normal. This work represents the first attempt to explore family caregiving processes (i.e. conversations) as they occur between family members and adds to the growing literature on the family caregiving experience. Implications for counselling practice working with individuals navigating the complex process of family caregiving are also drawn.
Aboriginal Students’ Achievement in Science Education: The Effect of Teaching Methods

description: Some authors assume that the academic difficulties encountered by Aboriginal students can be partly explained by the discrepancy between teaching methods and Aboriginal learning styles. However, this hypothesis lacks empirical foundations. Using pan-Canadian data, we tried to identify the most efficient teaching methods for Aboriginal students and assessed whether these methods were associated with performance differences between Aboriginals and non-Aboriginals in science education. Results revealed that judicious dosage and a proper balance among teaching methods seem to be required for students’ optimal achievement. In addition, only marginal differences were observed between Aboriginals and non-Aboriginals. However, standard assessment methods might partly explain these unexpected results.
