description: Antiphospholipid antibody syndrome (APS) has a broad spectrum of thrombotic and non-thrombotic clinical manifestations. Diagnosis requires a set of clinical criteria of thrombosis along with persistently positive anti-phospholipid antibody tests. In this report, we are presenting a case of APS, who is a 38 years old male, presented with complains of seizures and found to have stroke, which on further investigation revealed to have been caused possibly from a left atrial mass. High index of suspicion is required for the diagnosis of APS in young patients, who present with various neurological and cardiovascular manifestations, mostly secondary to thrombosis. APS usually is classified as primary and secondary, respectively, according to the absence or presence of an underlying disease as well as other autoimmune, malignancy, or drug-induced disorders.

description: Probabilistic program analysis aims to quantify the probability that a given program satisfies a required property. It has many potential applications, from program understanding and debugging to computing program reliability, compiler optimizations and quantitative information flow analysis for security. In these situations, it is usually more relevant to quantify the probability of satisfying/violating a given property than to just assess the possibility of such events to occur. In this work, we introduce an approach for probabilistic analysis of open programs (i.e. programs with undefined identifiers) based on game semantics and model counting. We use a symbolic representation of algorithmic game semantics to collect the symbolic constraints on the input data (context) that lead to the occurrence of the target events (e.g. satisfaction/violation of a given property). The constraints are then analyzed to quantify how likely is an input to satisfy them. We use model counting techniques to count the number of solutions (from a bounded integer domain) that satisfy given constraints. These counts are then used to assign probabilities to program executions and to assess the probability for the target event to occur at the desired level of confidence. Finally, we present the results of applying our approach to several interesting examples and illustrate the benefits they may offer.

description: Many applications heavily rely on piecewise triangular meshes to describe complex surface geometries. High-quality meshes significantly improve numerical simulations. In practice, however, one often has to deal with several challenges. Some regions in the initial mesh may be overrefined, others too coarse. Additionally, the triangles may be too thin or not properly oriented. We present a novel mesh adaptation procedure which greatly improves the problematic input mesh and overcomes all of these drawbacks. By coupling surface reconstruction via radial basis functions with the higher dimensional embedding surface remeshing technique, we can automatically generate anisotropic meshes. Moreover, we are not only able to fill or coarsen certain mesh regions but also align the triangles according to the curvature of the reconstructed surface. This yields an acceptable trade-off between computational complexity and accuracy.

description: Phosphorus (P) is an essential constituent of life but large P losses from agroecosystems and sanitation systems are a major source of eutrophication in water bodies.These losses are doubly detrimental as P in human excretions can be used for crop fertilization.Through a unique dataset of 20,000 French WasteWater Treatment Plants (WWTPs) operational measurements over two decades and a P mass balance, we assess the fate of human excretions and their agricultural potential.Despite 75% of French WWTPs sludge being spread on crops, only 50% of the excreted P makes it back to agroecosystems. This is among the highest rate in Western countries where assessments have been made.Meanwhile, another 35% of the excreted P ends up in surface waters or the environment through WWTP discharge, individual autonomous systems diffuse losses, and sewers leaks.The remaining 15% is incinerated or sent to landfills.Moreover, while WWTP removal efficiency increased in the 2000s, reaching an 80% national average, it has been followed by a decade of stagnation in every French basin.The final removal efficiency for each basin, from 65% to 85%, closely matches whether the area was defined as P-sensitive in the European directive.Our results suggest that recycling all P in excretions could help supply 7 to 34% of French food supply without changing the current food system.Reshaping agricultural systems (shifting to more plant-based diets, decreasing P losses and food waste) would enable to go even further on the road to food sufficiency.

Human-rights reporting and the Ghanaian press : pro-active rights reporting and its potential for human-rights growth
Creators: name: Peck, Sarah Mitchell

Year: 2004
Subjects: Human-rights

Press coverage

description: The following report is an attempt to assess the degree to which human-rights reporting in the Ghanaian Media actively promotes and addresses human-rights issues. This assessment draws upon both quantitative and qualitative study, as well as communication theory including agenda setting. Ghana serves as an example of a country striving to establish a free press and in many rights is achieving this goal. Ghana makes a compelling case study for a number of reasons, the most important being that the country’s press continuously grows and changes. New papers, including one weekly only focusing on human-rights issues, are sprouting up. While the government owns the largest two circulating papers, the independent press has emerged as a strong counter to these papers. Papers like The Ghanaian Chronicle and the Accra Daily Mail have high readerships. One can find in excess of 15 newspapers in Accra, as well as a growing berth of radio stations. The press is thriving. Over the years in Ghana, since it gained its independence in 1957, human-rights abuses have occurred with some frequency. The National Reconciliation Commission (NRC) of Ghana examines these abuses, and allows Ghanaians to come forward and tell their stories. It serves to create a record of violations of human-rights inflicted over the years. In and of itself, the NRC provides a step towards rectifying committed abuses, and preventing future ones. A recent publication produced by the Ghana Journalists Association brought to light the importance of media coverage about such issues, as well as the process and significance of the NRC. Previous literature indicates undeniable press ability to affect pressing matters like human-rights. However, the Ghanaian Press, like all media, must rely on consumer demands, which in Ghana largely revolve around politics. General knowledge of human-rights issues is low, and the press often does little to increase this knowledge. The extent to which human-rights reporting exists in Ghana is changing, but at a marginally slow pace. If expanded, press coverage could lead to a great improvement in the protection and enforcement of human-rights. The press can play a large role in the development of any society. This thesis posits that the amount of human-rights reporting in Ghana can directly affect the degree to which human-rights are respected. A pro-active approach to addressing human-rights issues in the press can change Ghanaians’ awareness of what their rights are – and then, an eventual change in to the level in which these rights are enforced

description: We determine solutions to 5D Einstein gravity with a discrete fifth dimension. The properties of the solutions depend on the discretization scheme we use and some of them have no continuum counterpart. In particular, we find that the neglect of the lapse field (along the discretized direction) gives rise to Randall-Sundrum type metric with a negative tension brane. However, no brane source is required. We show that this result is robust under changes in the discretization scheme. The inclusion of the lapse field gives rise to solutions whose continuum limit is gauge fixed by the discretization scheme. We find however one particular scheme which leads to an undetermined lapse reflecting the reparametrization invariance of the continuum theory. We also find other solutions, with no continuum counterpart with changes in the metric signature or avoidance of singularity. We show that the models allow a continuous mass spectrum for the gravitons with an effective 4D interaction at small scales. We also discuss some cosmological solutions.

Facies-guided 3-dimensional seismic modeling and reservoir characterization

description: A set of 3-D seismic models has been generated for a lower Miocene progradational micro-tidal shore-zone system at Powderhorn field, Calhoun County, Texas. These models are based on detailed mapping of facies and rock-properties that involves 250 m of stratigraphic section over an area of 13 by 9 km. Examination of logs from 115 wells shows that fourteen sandy depositional units averaging 3-30 m in thickness are encased in 15 shale units. Effective porosity, P-wave velocity and bulk density are calculated from suites of wireline logs in five recent wells, and then expanded to older wells through regression with SP and resistivity logs. Property mapping in two dimensions is accomplished by employing the directional weighted average method (DWA), which simulates the hand mapping of a geoscientist by incorporating the directional and geometrical information gained from facies analysis into gridding. This biased mapping approach produces a striking visual impact compared to unbiased computer mapping. A predictogram analysis also confirmed that DWA is better than other computer algorithms for generating sandstone thickness maps, though rock-property pedictions were not improved. The predictogram measures information content of both wells and seismic data, and can help to explain the mistie between synthetic and real seismic traces at well locations. Idealized 3-dimensional seismic models are generated by convolving a Ricker wavelet with the primary reflection coefficient series from stacked 2-D P-wave velocity and impedance models. The idealized stratal slices show that to achieve the best image of depositional facies, seismic frequency should be tuned to the maximum sandstone thickness. Framework sand bodies surrounded by muddy deposits are well illustrated. Clean sandstone and pure shale have similar impedance, creating ambiguous amplitude patterns. The stratal resolution of seismic imagery depends not only on wavelet frequency, but also on the magnitude of geological interference. This 3-D model also provides a realistic basis for evaluating the expected hydrocarbon detectability for the reservoirs in this evironment. Examples illustrate that the presence of gas should produce stratal slice amplitude anomalies that are very large compared to the facies-related amplitude variations. Seismic events do not necessarily follow geological time lines. The correlation error of peak picking is often large enough to distort reservoir facies image on stratal slices. In some cases, event crossing connects sand bodies from different units to form a new event. An event tying as many as six depositional units over 50 m has been observed. Phantom mapping produces truer stratal slices, making it possible to map detailed depositional facies within reservoir sequences from 3-D seismic data

description: In this paper we present a detailed and exact study of the probability density function $P(F)$ of the total force $F$ acting on a point particle belonging to a perturbed lattice of identical point sources of a power law pair interaction. The main results concern the large $F$ tail of $P(F)$ for which two cases are mainly distinguished: (i) Gaussian-like fast decreasing $P(F)$ for lattice with perturbations forbidding any pair of particles to be found arbitrarily close to one each other; (ii) Lévy-like power law decreasing $P(F)$ when this possibility is instead permitted. It is important to note that in the second case the exponent of the power law tail of $P(F)$ is the same for all perturbation (apart from very singular cases), and is in an one to one correspondence with the exponent characterizing the behavior of the pair interaction with the distance between the two particles.

description: Parametric Markov chains have been introduced as a model for families of stochastic systems that rely on the same graph structure, but differ in the concrete transition probabilities. The latter are specified by polynomial constraints for the parameters. Among the tasks typically addressed in the analysis of parametric Markov chains are (1) the computation of closed-form solutions for reachabilty probabilities and other quantitative measures and (2) finding symbolic representations of the set of parameter valuations for which a given temporal logical formula holds as well as (3) the decision variant of (2) that asks whether there exists a parameter valuation where a temporal logical formula holds. Our contribution to (1) is to show that existing implementations for computing rational functions for reachability probabilities or expected costs in parametric Markov chains can be improved by using fraction-free Gaussian elimination, a long-known technique for linear equation systems with parametric coefficients. Our contribution to (2) and (3) is a complexity-theoretic discussion of the model checking problem for parametric Markov chains and probabilistic computation tree logic (PCTL) formulas. We present an exponential-time algorithm for (2) and a PSPACE upper bound for (3). Moreover, we identify fragments of PCTL and subclasses of parametric Markov chains where (1) and (3) are solvable in polynomial time and establish NP-hardness for other PCTL fragments.

description: Fix r ≥ 2 and a collection of r-uniform hypergraphs . What is the minimum number of edges in an -free r-uniform hypergraph with chromatic number greater than k? We investigate this question for various . Our results include the following: An (r,l)-system is an r-uniform hypergraph with every two edges sharing at most l vertices. For k sufficiently large, there is an (r,l)-system with chromatic number greater than k and number of edges at most c(kr−1 log k)l/(l−1), where This improves on the previous best bounds of Kostochka et al. (Random Structures Algorithms 19 (2001), 87–98). The upper bound is sharp apart from the constant c as shown in (Random Structures Algorithms 19 (2001) 87–98). The minimum number of edges in an r-uniform hypergraph with independent neighborhoods and chromatic number greater than k is of order kr+1/(r−1) log O(1)k as k ∞. This generalizes (aside from logarithmic factors) a result of Gimbel and Thomassen (Discrete Mathematics 219 (2000), 275–277) for triangle-free graphs. Let T be an r-uniform hypertree of t edges. Then every T-free r-uniform hypergraph has chromatic number at most 2(r − 1)(t − 1) + 1. This generalizes the well-known fact that every T-free graph has chromatic number at most t. Several open problems and conjectures are also posed.

description: I briefly review the X/UV absorber models and show that the observations of NLS1s are generally consistent with the models. The covering factor of absorbers in NLS1s is likely to be high and there is some evidence of super-solar metallicities. I argue that NLS1s may be active galaxies in the early stage of their evolution and as such, may be low luminosity, low redshift analogues of the high redshift quasars. NLS1s may reside in rejuvenated gas-rich galaxies. I also propose that the high Fe II emission in NLS1s may be a direct consequence of their large accretion rate and so a collisional ionization origin of FeII is favored.

description: We study the Bianchi-I cosmological model motivated by signals of statistical isotropy violation seen in cosmic microwave background (CMB) observations and others. To that end, we consider various kinds of anisotropic matter that source anisotropy in our model, specifically Cosmic strings, Magnetic fields, Domain walls and Lorentz violation generated magnetic fields. These anisotropic matter sources, taking one at a time, are studied for their co-evolution with standard model (isotropic) sources viz., dust-like (dark/normal) matter, and dark energy modelled as cosmological constant. We constrain the Hubble parameter, density fractions of anisotropic matter, cold dark matter (CDM), and dark energy ($Λ$) in a Bianchi-I universe with planar symmetry i.e., which has a global ellipsoidal geometry, and try to find signatures of a cosmic preferred axis if any. The latest compilation of Type Ia Supernova (SNIa) data from Pantheon+SH0ES collaboration is used in our analysis to obtain constraints on cosmological parameters and any preferred axis for our universe. In our analysis, we found mild evidence for a cosmic preferred axis. It is interesting to note that this preferred axis lies broadly in the vicinity of other prominent cosmic anisotropy axes reported in the literature from diverse data sets. Also we find some evidence for non-zero (negative) cosmic shear and eccentricity that characterize different expansion rates in different directions and deviation from an isotropic scale factor respectively. The energy density fractions of two of the sources considered are found to be non-zero at a $2σ$ confidence level. To be more conclusive, we require more SNIa host galaxy data for tighter constraints on distance and absolute magnitude calibration which are expected to be available from the future JWST observations and others.

description: Mesoscale objects with unusual structural features may serve as the analogues of atoms in the design of larger-scale materials with novel optical, electronic or mechanical behaviour. In this paper we investigate the structural features and the equilibrium dynamics of micron-scale spherical crystals formed by polystyrene particles adsorbed on the surface of a spherical water droplet. The ground state of sufficiently large crystals possesses finite-length grain boundaries (scars). We determine the elastic response of the crystal by measuring single-particle diffusion and quantify the fluctuations of individual dislocations about their equilibrium positions within a scar determining the dislocation spring constants. We observe rapid dislocation glide with fluctuations over the barriers separating one local Peierls minimum from the next and rather weak binding of dislocations to their associated scars. The long-distance (renormalised) dislocation diffusion glide constant is extracted directly from the experimental data and is found to be moderately faster than single particle diffusion. We are also able to determine the parameters of the Peierls potential induced by the underlying crystalline lattice.

description: Stenosis in internal jugular veins (IJVs) are frequently associated to pathological venous circulation and insufficient cerebral blood drainage. In this work, we set up a computational framework to assess the relevance of IJV stenoses through numerical simulation, combining medical imaging, patient-specific data and a mathematical model for venous occlusions. Coupling a three-dimensional (3D) description of blood flow in IJVs with a reduced one-dimesional model (1D) for major intracranial veins, we are able to model different anatomical configurations, an aspect of importance to understand the impact of IJV stenosis in intracranial venous haemodynamics. We investigate several stenotic configurations in a physiologic patient-specific regime, quantifying the effect of the stenosis in terms of venous pressure increase and wall shear stress patterns. Simulation results are in qualitative agreement with reported pressure anomalies in pathological cases. Moreover, they demonstrate the potential of the proposed multiscale framework for individual-based studies and computer-aided diagnosis.

description: In this article, the optimal control of a cooling line for production of dual phase steel in a hot rolling process is discussed. In order to achieve a desired dual phase steel microstructure an optimal cooling strategy has to be found. The cooling strategy should be such that a desired final distribution of ferrite in the steel slab is reached most accurately. This problem has been solved by means of mathematical control theory. The results of the optimal control of the cooling line have been verified in hot rolling experiments at the pilot hot rolling mill at the Institute for Metal Forming (IMF), TU Bergakademie Freiberg.

description: Open systems with balanced gain and loss, described by parity-time PT-symmetric Hamiltonians have been deeply explored over the past decade. Most explorations are limited to finite discrete models (in real or reciprocal spaces) or continuum problems in one dimension. As a result, these models do not leverage the complexity and variability of two-dimensional continuum problems on a compact support. Here, we investigate eigenvalues of the Schrodinger equation on a disk with zero boundary condition, in the presence of constant, PT-symmetric, gain-loss potential that is confined to two mirror-symmetric disks. We find a rich variety of exceptional points, re-entrant PT-symmetric phases, and a non-monotonic dependence of the PT-symmetry breaking threshold on the system parameters. By comparing results of two model variations, we show that this simple model of a multi-core fiber supports propagating modes in the presence of gain and loss.

description: A quark model which includes both scalar and vector contributions to the reaction mechanism (SV quark model) is used in a DWBA calculation of $\bar ΛΛ$ production in $\bar p p$ interractions. Total and differential cross-sections, polarizations, depolarizations, and spin-correlattion coefficients are computed for laboratory momenta from threshold to 1695 MeV/c. The free parameters of the calculation are the scalar and vector strengths, a quark cluster size parameter,and the parameters of the unknown $\bar ΛΛ$ potentials. Good agreement with experiment is found for constructive interference of the scalar and vector terms, and for $\bar ΛΛ$ potentials which differ from those suggested by several authors on the basis of SU(3) arguments. The fit to the data is better than that obtained by other quark models, which use only scalar $or$ vector annihilation terms. The agreement with experiment is also better than that found in meson-exchange models. The recent suggestion[1] that measurement of the depolarization parameter $D_{nn}$ can be used to discriminatebetween meson-exchange and quark models is examined in detail. We conclude that a measurement of $D_{nn}$ will provide a test of which of these models, as presently constructed,is the more appropriate description of strangeness production in the $\bar p p \ rightarrow \bar ΛΛ$ reaction.

description: The aim of this paper is to prove an isoperimetric inequality relative to a d-dimensional, bounded, convex domain &Omega intersected with balls with a uniform relative isoperimetric constant, independent of the size of the radius r>0 and the position y∈cl(&Omega) of the center of the ball. For this, uniform Sobolev, Poincaré and Poincaré-Sobolev inequalities are deduced for classes of (not necessarily convex) domains that satisfy a uniform cone property. It is shown that the constants in all of these inequalities solely depend on the dimensions of the cone, space dimension d, the diameter of the domain and the integrability exponent p∈[1,d).

description: Public space utilization is crucial for urban developers to understand how efficient a place is being occupied in order to improve existing or future infrastructures. In a smart cities approach, implementing public space monitoring with Internet-of-Things (IoT) sensors appear to be a viable solution. However, choice of sensors often is a challenging problem and often linked with scalability, coverage, energy consumption, accuracy, and privacy. To get the most from low cost sensor with aforementioned design in mind, we proposed data processing modules for capturing public space utilization with Renewable Wireless Sensor Network (RWSN) platform using pyroelectric infrared (PIR) and analog sound sensor. We first proposed a calibration process to remove false alarm of PIR sensor due to the impact of weather and environment. We then demonstrate how the sounds sensor can be processed to provide various insight of a public space. Lastly, we fused both sensors and study a particular public space utilization based on one month data to unveil its usage.

description: The demographic composition of the United States is changing and Latinos, are becoming this nation's fastest growing ethnic minority. These changes will alter the makeup of persons in the work place. It is estimated that by the year 2000, the the majority of persons entering the work place will be ethnic minorities and women. These new workers, who are culturally different from the dominant White ethnic group, have experiences that are seldom heard and important to understand. This study examined the experiences of three successful Latina broadcast journalists in Texas. The ethnographic data gathered from interviews with the three women provided information regarding their experiences with racism, tokenism, and their coping strategies within the newsroom This research allows readers to better understand the challenges facing both the media organizations and the Latinas they hire

description: We describe how a stable effective theory in which particles of the same fermion number attract may spontaneously break Lorentz invariance by giving non-zero fermion number density to the vacuum (and therefore dynamically generating a chemical potential term). This mecanism yields a finite vacuum expectation value $$ which we consider in the context of proposed models that require such a breaking of Lorentz invariance in order to yield composite degrees of freedom that act approximately like gauge bosons. We also make general remarks about how the background source provided by $$ could relate to work on signals of Lorentz violation in electrodynamics.

Eigenvector 1: An Optimal Correlation Space for Active Galactic Nuclei

description: We identify a correlation space involving optical and UV emission line parameters as well as the soft X-ray spectral index that provides optimal discrimination between all principal classes of active galactic nuclei. Most of the sources in our three high quality data samples show a strong intercorrelation with narrow line Seyfert 1 (NLSy1) galaxies and steep spectrum radio galaxies occupying opposite extrema in the space. NLSy1 sources show a clear continuity with broader line sources indicating that they are not a disjoint class of AGN as is sometimes suggested. We interpret the principal intercorrelation in the parameter space as being driven by AGN luminosity to black hole mass ratio (L/M prop. to the Eddington ratio). Source orientation no doubt also plays an important role but it is not yet clear whether FWHM H beta or CIV 1549 line shift is the better indicator. We tentatively identify two RQ populations: an almost pure RQ population A with FWHM<=4000 and population B which occupies the same parameter domain as the flat spectrum RL sources. A possible interpretation sees Pop. A/NLSy1 as lower mass/high accretion rate sources and Pop. B/RL sources the opposite.

description: The military is a high-risk environment for occupational deafness. Acoustic trauma is a sensorineural hearing disorder caused by impulsive loud noise with a frequency range of 2-6 kHz. This study aims to assess the occurrence of acoustic trauma on a Howitzer 105 gunner. Indonesian military currently doesn’t have hearing conservation program. The work environment of the armed forces places military personnels to be at risk of suffering occupational hearing loss caused by the use of main equipments for system of defense as one of the skill requirements. The research used a prospective period method from July 7 to July 10, 2014, with the focus being new recruit soldiers in the Indonesian Army's Artillery Academy. The subjects were divided into two groups: Exposed (17 gunners) and non-exposed (stae the number of subjects). Subjects' identities, medical histories, and symptoms after firing were all reported on a questionnaire. The Integrating Sound Level Meter and Real Time Analyzer were used to measure the sound intensity and frequency. Pure tone audiometry was used to assess hearing function. Fisher Exact test was used to determine the value of the data (p<0.05) The findings of this study revealed that the sound pressure level of a Howitzer 105 artillery weapon totaled 148.6 dBA with a frequency that decayed to 60 dBA for 2 seconds, while the impulsive sound intensity received at a distance of one metre exceeded the 1998th National Institute for Occupational Safety and Health (NIOSH) criteria. Acoustic trauma on the gunner without ear protection is significant at 23.5% (p0.05), with symptoms of tinnitus and temporary hearing disorders (1 day) being only 6% and not significant (p>0.05).

description: This paper presents a novel model order reduction technique tailored for power systems with a large share of inverter-based energy resources. Such systems exhibit an increased level of dynamic stiffness compared to traditional power systems, posing challenges for time-domain simulations and control design. Our approach involves rotation of the coordinate system of a linearized system using a transformation matrix derived from the real Jordan canonical form, leading to mode decoupling. The fast modes are then truncated in the rotated coordinate system to obtain a lower-order model with reduced stiffness. Applying the same transformation to the original nonlinear system results in an approximate separation of slow and fast states, which can be truncated to reduce the stiffness. The resulting reduced-order model demonstrates an accurate time-domain performance, the slow eigenvalues of the linearized system are correctly preserved, and a reduction in the model stiffness is achieved, allowing for accurate integration with increased step size. Our methodology is assessed in detail for a 3-bus system with generation units involving grid-forming/following converters and synchronous machines, where it allows for a computational speed-up of up to 100x compared to the original system. Several standard larger test systems are also considered.

description: Probabilistic constraints represent a major model of stochastic optimization. A possible approach for solving probabilistically constrained optimization problems consists in applying nonlinear programming methods. In order to do so, one has to provide sufficiently precise approximations for values and gradients of probability functions. For linear probabilistic constraints under Gaussian distribution this can be successfully done by analytically reducing these values and gradients to values of Gaussian distribution functions and computing the latter, for instance, by Genz' code. For nonlinear models one may fall back on the spherical-radial decomposition of Gaussian random vectors and apply, for instance, Deák's sampling scheme for the uniform distribution on the sphere in order to compute values of corresponding probability functions. The present paper demonstrates how the same sampling scheme can be used in order to simultaneously compute gradients of these probability functions. More precisely, we prove a formula representing these gradients in the Gaussian case as a certain integral over the sphere again. Later, the result is extended to alternative distributions with an emphasis on the multivariate Student (or T-) distribution.
