description: A Space-Time Block Code (STBC) in $K$ symbols (variables) is called $g$-group decodable STBC if its maximum-likelihood decoding metric can be written as a sum of $g$ terms such that each term is a function of a subset of the $K$ variables and each variable appears in only one term. In this paper we provide a general structure of the weight matrices of multi-group decodable codes using Clifford algebras. Without assuming that the number of variables in each group to be the same, a method of explicitly constructing the weight matrices of full-diversity, delay-optimal $g$-group decodable codes is presented for arbitrary number of antennas. For the special case of $N_t=2^a$ we construct two subclass of codes: (i) A class of $2a$-group decodable codes with rate $\frac{a}{2^{(a-1)}}$, which is, equivalently, a class of Single-Symbol Decodable codes, (ii) A class of $(2a-2)$-group decodable with rate $\frac{(a-1)}{2^{(a-2)}}$, i.e., a class of Double-Symbol Decodable codes. Simulation results show that the DSD codes of this paper perform better than previously known Quasi-Orthogonal Designs.

description: Standard calculations suggest that the entropy of our universe is dominated by black holes, whose entropy is of order their area in Planck units, although they comprise only a tiny fraction of its total energy. Statistical entropy is the logarithm of the number of microstates consistent with the observed macroscopic properties of a system, hence a measure of uncertainty about its precise state. Therefore, assuming unitarity in black hole evaporation, the standard results suggest that the largest uncertainty in the future quantum state of the universe is due to the Hawking radiation from evaporating black holes. However, the entropy of the matter precursors to astrophysical black holes is enormously less than that given by area entropy. If unitarity relates the future radiation states to the black hole precursor states, then the standard results are highly misleading, at least for an observer that can differentiate the individual states of the Hawking radiation.

description: We show that, due to the weak ferromagnetism of La$_{2-x}$Sr$_x$CuO$_4$, an external magnetic field leads to a dimensional crossover 2D $\to$ 3D for the in-plane transport. The crossover results in an increase of the hole's localization length and hence in a dramatic negative magnetoresistance in the variable range hopping regime. This mechanism quantitatively explains puzzling experimental data on the negative magnetoresistance in the Néel phase of La$_{2-x}$Sr$_x$CuO$_4$.

description: Basalt rock is very fine-grained, almost glassy, and impervious in the Deccan trap area. It coversMaharashtra and parts of Madhya Pradesh. Since it is an impervious geological zone, rainwater harvestingand hydro landscape planning will be the best way to develop a water body. Chandrapur is one ofMaharashtra's eleven Vidarbha districts. It borders Andhra Pradesh on the south, Garhchiroli on the east,Gondia, Bhandara, Nagpur, and Wardha on the north, and Yavatmal on the west. Wardha and Waingangarivers border the district. 19°30'–20°45' north latitudes and 78°46'–80°00' east longitudes define thedistrict. Since annual rainfall averages 1227.0 mm, humidity ranges from 17%-89%, and temperaturesrange from 4deg C to 44deg C. A lake will improve the hydro landscape and accommodate flooded watersince the region receives 5.0 lakh to 6.0 lakh cubic meters of water annually. The impervious Deccan trapcauses flooding and water logging in local depressions due to its good runoff. The study area is in DeccanTrap, where low rainfall infiltration and high runoff cause waterlogging, flooding, and ugly hydrolandscapes. The lake is suggested to improve the hydro landscape and accommodate flooding andwaterlogging.

description: In the field of parametric partial differential equations, shape optimization represents a challenging problem due to the required computational resources. In this contribution, a data-driven framework involving multiple reduction techniques is proposed to reduce such computational burden. Proper orthogonal decomposition (POD) and active subspace genetic algorithm (ASGA) are applied for a dimensional reduction of the original (high fidelity) model and for an efficient genetic optimization based on active subspace property. The parameterization of the shape is applied directly to the computational mesh, propagating the generic deformation map applied to the surface (of the object to optimize) to the mesh nodes using a radial basis function (RBF) interpolation. Thus, topology and quality of the original mesh are preserved, enabling application of POD-based reduced order modeling techniques, and avoiding the necessity of additional meshing steps. Model order reduction is performed coupling POD and Gaussian process regression (GPR) in a data-driven fashion. The framework is validated on a benchmark ship.

1992 Safety Belt Usage Survey and Evaluation of Effectiveness in Kentucky
Creators: name: Agent, Kenneth R.
Publisher: name: Kentucky Transportation Center, University of Kentucky
Year: 1992
Subjects: subject: Transportation Engineering

description: The objective of the survey was to establish 1992 safety belt and child safety seat usage rates in Kentucky. Data were collected at 100 sites and combined based on vehicle miles travelled for a given type of highway, rural or urban location, and county population category. Also included in this report is an analysis of accident records evaluating the effectiveness of safety belts.  Statewide usage rates were 41 percent for drivers and front-seat passengers (over 19 years of age) and 62 percent for children under four years of age (front and rear seats). Driver usage rates increased in 1992 compared to 1991, however, the amount of the increase was less than in previous years. Rates were highest on interstate highways and lowest on rural, non-interstate highways.  Benefits in the reduction of injures for occupants involved in police-reported accidents wearing a safety belt or in a safety seat were shown through the analysis of accident records. For example, a 52 percent reduction in fatal or incapacitating injuries was determined for drivers wearing a safety belt compared to those who were not restrained.  The increased usage that resulted in Fayette County and Jefferson County after enactment of local mandatory usage laws was shown. Increased usage rates in Covington and Bowling Green would also be related to passage of local laws. The recommendation is that a statewide mandatory safety belt law should be passed or, in lieu of a statewide law, additional local governments should pass such a law.

Metastable dynamics of convection-diffusion-reaction equations
Creators: name: Sun, Xiaodi
Publisher: name: University of British Columbia
Year: 2009

description: Metastable dynamics, which qualitatively refers to physical processes that involve an extremely slow approach to their final equilibrium states, is often associated with singularly perturbed convection-diffusion-reaction equations. A problem exhibits metastable behavior when the approach to equilibrium occurs on a time-scale of order 0(e?), where C > 0 and ε is the singular perturbation parameter. The studies of these mathematical models are not only significant in their own right, but also useful in simulating and explaining observed physical phenomena and exploring possibly certain unknown ones. A typical common characteristic associated with these convection-diffusion-reaction equations is that the linearized operator is exponentially ill-conditioned. By exponential ill-conditioning we mean that the linearized operator has an exponentially small eigenvalue. As a result, conventional analytical methods and numerical schemes may fail to provide accurate information about the metastable behavior. This thesis is concerned with developing a systematic and robust approach based on asymptotic and numerical methods to quantify the dynamic metastability associated with various problems. Using the asymptotic method called the projection method which was originated by Ward in [108], we have succeeded in deriving ordinary differential equations (ODEs) or differential algebraic equations (DAEs) which characterize the metastable patterns for several problems, including, the phase separation of a binary alloy modeled by the viscous Cahn-Hilliard equation, the upward propagation of a flame front in a vertical channel modeled by the Mikishev-Rakib-Sivashinsky equation, and two problems in slowly varying geometries. The main role of our numerical method called the transverse method of lines is to give a numerical justification of these ODEs/DAEs and to provide useful information about the metastable solutions in their transient phases and collapse phases during which our asymptotic method fails. From the numerical point of view, little is known of the nature concerning the convergence and stability of any numerical scheme that computes metastable behavior, as a result of the exponential ill-conditioning of the linearized operator. In this thesis, several finite difference schemes and their convergence are analyzed rigorously for a boundary layer resonance problem. Our results from this problem are shown numerically to be also valid for other nonlinear metastable problems and some guidelines in designing effective numerical schemes are provided. The analytical and numerical results show that our approach is a powerful and general tool to quantitatively study the metastable patterns in various physical problems. In addition, the metastable behavior revealed by our analysis appears to be also rather interesting from the viewpoint of physical applications.

description: IGR J17091--3624 is a transient galactic black hole which has a distinct quasi-periodic variability known as `heartbeat', similar to the one observed in GRS 1915+105. In this paper, we report the results of $\sim 125$ ks \textit{AstroSat} observations of this source during the 2016 outburst. For the first time a double peaked QPO (DPQ) is detected in a few time segments of this source with a difference of $δf ~\sim12$ mHz between the two peaks. The nature of the DPQ was studied based on hardness ratios and using the static as well as the dynamic power spectrum. Additionally, a low frequency (25--48 mHz) `heartbeat' single peak QPO (SPQ) was observed at different intervals of time along with harmonics ($50-95$ mHz). Broadband spectra in the range $0.7-23$ keV, obtained with \textit{SXT} and \textit{LAXPC}, could be fitted well with combination of a thermal Comptonisation and a multicolour disc component model. During \textit{AstroSat} observation, the source was in the Soft-Intermediate State (SIMS) as observed with \textit{Swift/XRT}. We present a comparative study of the `heartbeat' state variability in IGR J17091--3624 with GRS 1915+105. Significant difference in the timing properties is observed although spectral parameters ($Γ\sim2.1-2.4$ and $T_\mathrm{max}\sim0.6-0.8$ keV) in the broad energy band remain similar. Spectral properties of segments exhibiting SPQ and DPQ are further studied using simple phase resolved spectroscopy which does not show a significant difference. Based on the model parameters, we obtain the maximum ratio of mass accretion rate in GRS 1915+105 to that in IGR J17091--3624 as $\sim25:1$. We discuss the implications of our findings and comment on the physical origin of these exotic variabilities.

description: We perform one-dimensional radiation-hydrodynamic simulations of energetic supernova ejecta colliding with a massive circumstellar medium (CSM) aiming at explaining SN 2016aps, likely the brightest supernova observed to date. SN 2016aps was a superluminous Type-IIn SN, which released as much as $\gtrsim 5\times 10^{51}$ erg of thermal radiation. Our results suggest that the multi-band light curve of SN 2016aps is well explained by the collision of a $30\ M_\odot$ SN ejecta with the explosion energy of $10^{52}$ erg and a $\simeq 8\ M_\odot$ wind-like CSM with the outer radius of $10^{16}$ cm, i.e., a hypernova explosion embedded in a massive CSM. This finding indicates that very massive stars with initial masses larger than $40\ M_\odot$, which supposedly produce highly energetic SNe, occasionally eject their hydrogen-rich envelopes shortly before the core-collapse. We suggest that the pulsational pair-instability SNe may provide a natural explanation for the massive CSM and the energetic explosion. We also provide the relations between the peak luminosity, the radiated energy, and the rise time for interacting SNe with the kinetic energy of $10^{52}$ erg, which can be used for interpreting SN 2016aps-like objects in future surveys.

description: An investigation on stochastic deflection of high-energy charged particles in a bent crystal was carried out. In particular, we investigated the deflection efficiency under axial confinement of both positively and negatively charged particles as a function of the crystal orientation, the choice of the bending plane, and of the charge sign. Analytic estimations and numerical simulations were compared with dedicated experiments at the H4 secondary beam line of SPS North Area, with 120 GeV/$c$ electrons and positrons. In the work presented in this article, the optimal orientations of the plane of bending of the crystal, which allow deflecting the largest number of charged particles using a bent crystal in axial orientation, were found.

description: New theoretical and experimental investigation of the occupied and unoccupied local electronic density of states (DOS) are reported for alpha-Li3N. Band structure and density functional theory calculations confirm the absence of covalent bonding character. However, real-space full-multiple-scattering (RSFMS) calculations of the occupied local DOS finds less extreme nominal valences than have previously been proposed. Nonresonant inelastic x-ray scattering (NRIXS), RSFMS calculations, and calculations based on the Bethe-Salpeter equation are used to characterize the unoccupied electronic final states local to both the Li and N sites. There is good agreement between experiment and theory. Throughout the Li 1s near-edge region, both experiment and theory find strong similarities in the s- and p-type components of the unoccupied local final density of states projected onto an orbital angular momentum basis (l-DOS). An unexpected, significant correspondence exists between the near-edge spectra for the Li 1s and N 1s initial states. We argue that both spectra are sampling essentially the same final density of states due to the combination of long core-hole lifetimes, long photoelectron lifetimes, and the fact that orbital angular momentum is the same for all relevant initial states. Such considerations may be generically applicable for low atomic number compounds.

Metallicity Calibrations and the Mass-Metallicity Relation for Star-Forming Galaxies

Subjects: subject: Astrophysics (astro-ph)

description: (Abridged) We investigate the effect of metallicity calibrations, AGN classification, and aperture covering fraction on the local mass-metallicity (MZ) relation using 27,730 star-forming galaxies from the Sloan Digital Sky Survey (SDSS) Data Release 4. We analyse the SDSS MZ relation with 10 metallicity calibrations, including theoretical and empirical methods. We show that the choice of metallicity calibration has a significant effect on the shape and y-intercept(12+log(O/H)) of the MZ relation. The absolute metallicity scale (y-int) varies up to 0.7 dex, depending on the calibration used, and the change in shape is substantial. These results indicate that it is critical to use the same metallicity calibration when comparing different luminosity-metallicity or mass-metallicity relations. We present new metallicity conversions that allow metallicities that have been derived using different strong-line calibrations to be converted to the same base calibration. These conversions facilitate comparisons between different samples, particularly comparisons between galaxies at different redshifts for which different suites of emission-lines are available.Our new conversions successfully remove the large 0.7 dex discrepancies between the metallicity calibrations, and we reach agreement in the MZ relation to within 0.03 dex on average. We find that different AGN classification methods have negligible effect on the SDSS MZ relation. We compare the SDSS MZ relation with nuclear and global relations from the Nearby Field Galaxy Survey (NFGS). The turn over of the MZ relation depends on aperture covering fraction. We find that a lower redshift limit of z<0.04 is insufficient for avoiding aperture effects in fiber spectra of the highest stellar mass galaxies.

Subjects: subject: Transportation Engineering

description: The objective of this study was to report the results of the continued monitoring of the performance of the modified turned-down guardrail end treatment (Type 7) in traffic accidents. Data for a total of 67 accidents involving the modified turned-down guardrail end treatment were identified. Performance was classified as proper in 51 of the 61 accidents (84 percent) in which it was determined. In the majority of the accidents in which proper performance occurred, the vehicle either traveled onto the top at the guardrail beyond the breakaway section or broke through the breakaway posts and proceeded behind the guardrail.  The performance of this 'weakened turned-down' end treatment has shown that continued use is warranted. Although lull scale crash tests have not been conducted for this end treatment, its performance in the field in actual accidents warrants further use. The rollover problem experienced with the original 'stiff' turned-down design has been substantially reduced. The remaining question concerning the rollover problem relates to the small car. When roadway geometries do not permit the guardrail end to be properly buried in a cut slope and conditions for the use of the BCT cannot be met, the Type 7 end treatment provides a practical alternative.

description: The characteristics of traffic accidents involving teenage (16 to 19 years of age) drivers are summarized in this report and compared to all accidents. This was accomplished through an analysis of statewide accident data for a three-year period (1989 through 1991). Counties having the highest overrepresentation of accidents involving teenage drivers were identified. The status of highway safety programs currently in place in school districts in Kentucky is presented. A survey was sent to 182 school districts in Kentucky with a 64 percent response rate obtained. Relevant literature was reviewed, and summary statements are given in the Appendix. This summary of the literature gives an overview of recognized problems associated with young drivers and programs which have been recommended to address these problems. The information given in this report may be used in the process of developing a statewide youth traffic safety program. Recommendations for implementation of such a program are given.

description: This report includes an analysis of traffic accident data in Kentucky tor the years of 1987-1991. A primary objective of this study was to determine average accident statistics for Kentucky highways. Average and critical number and rates of accidents were calculated for various types of highways in rural and urban areas. These data can be used in Kentucky's procedure to identify locations that have abnormal rates or numbers of accidents.  Another objective of this study was to provide data which can be used in the preparation of the problem identification portion of Kentucky's Annual Highway Safety Plan. County and city accident statistics were analyzed. A summary of results and recommendations in several problem identification areas is presented. These general areas include alcohol, occupant protection, speed, pedestrians, bicycles, motorcycles, and vehicle defects. Other areas included in the analysis included drugs, school bus accidents, and truck accidents.

description: Non-Hermiticity is expected to add far more physical features to the already rich Floquet topological phases of matter. Nevertheless, a systematic approach to characterize non-Hermitian Floquet topological matter is still lacking. In this work we introduce a dual scheme to characterize the topology of non-Hermitian Floquet systems in momentum space and in real space, using a piecewise quenched nonreciprocal Su-Schrieffer-Heeger model for our case studies. Under the periodic boundary condition, topological phases are characterized by a pair of experimentally accessible winding numbers that make jumps between integers and half-integers. Under the open boundary condition, a Floquet version of the so-called open boundary winding number is found to be integers and can predict the number of pairs of zero and $π$ Floquet edge modes coexisting with the non-Hermitian skin effect. Our results indicate that a dual characterization of non-Hermitian Floquet topological matter is necessary and also feasible because the formidable task of constructing the celebrated generalized Brillouin zone for non-Hermitian Floquet systems with multiple hopping length scales can be avoided. This work hence paves a way for further studies of non-Hermitian physics in non-equilibrium systems.

description: Η 2,3 διοξυγονάση της ινδολεαμίνης είναι ένα καταβολικό ένζυμο που εμπλέκεται στο καταβολισμό ενός από τα πιο απαραίτητα αμινοξέα, της L-τρυπτοφάνης. Η έκφραση της IDO εμπλέκεται σε φαινόμενα καταστολής της ανοσιακής απάντησης, όπως η ανοχή που εμφανίζει η μητέρα κατά την εγκυμοσύνη προς το αλλογενές έμβρυο. Τελευταία, διάφορες μελέτες εστιάζονται σε αυτήν την πρωτεΐνη, καθώς φαίνεται να διαδραματίζει σημαντικό ρόλο στην διαφυγή των καρκινικών κυττάρων από την ανοσιακή απάντηση. Η έκφραση του ενζύμου αυτού έχει μελετηθεί σε πολλούς καρκινικούς τύπους, συμπεριλαμβανομένου του NSCLC, ωστόσο ποτέ δεν έχει συμπεριληφθεί στη μελέτη δείγμα μη προσβεβλημένου αυτόλογου ιστού από καρκινοπαθείς. Στην παρούσα μελέτη διερευνήθηκε η έκφραση της IDO τόσο σε καρκινικό αλλά και μη προσβεβλημένο ιστό ασθενών με NSCLC, καθώς και σε δείγματα ιστών από υγιή άτομα και σε καρκινικές σειρές. Η IDO ανιχνεύθηκε σε καρκινικές σειρές από αδενοκαρκίνωμα παχέως εντέρου και πνεύμονα, σε διεγερμένα μονοκύτταρα περιφερικού αίματος και σε μερικούς ιστούς υγιών ατόμων, όπως στον πνεύμονα, τον πλακούντα και το σκελετικό μυ. Η ανάλυση έδειξε αυξημένη έκφραση στον καρκινικό ιστό ασθενών με NSCLC, ενώ παράλληλα διαπιστώθηκε έκφραση του mRNA της IDO και στο μη προσβεβλημένο τμήμα ιστού, σε χαμηλότερα όμως επίπεδα. Επίσης εντοπίστηκε μια ασθενής τάση θετικής συσχέτισης της έκφρασης της IDO με τη βαρύτητα της ασθένειας στους ίδιους ασθενείς.
description: Indoleamine 2,3 dioxygenase is a catabolic enzyme that degrates one of the most important aminoacids, L-tryptophon. Lately, a number of studies focus on this protein as it plays an important role in tumor immune escape. In the present study IDO expression was investigated in cancerous and non-infected tissue of patients with USCLC, as well in tissue samples of healthy individuals and tumor cell lines. IDO expression was detected in colon and lung adenocarcinoma. Cell lines, PHA blasted PBMC's and some healthy tissues, including lung, placenta and sceletal muscle. Analysis demonstrated increased IDO expression in the cancerous tissue of pateints with NSCLC, though IDON in RNA expression was also detected in the non-malignant tissue in lower levels. Finally a weak correlation was detected between IDO expression and stage of the disease in the same patients

description: Continuous GPS and broadband seismic monitoring have revealed a variety of disparate slip patterns especially in shallow dipping subduction zones, among which regular earthquakes, slow slip events and silent quakes1,2. Slow slip events are sometimes accompanied by Non Volcanic Tremors (NVT), which origin remains unclear3, either related to fluid migration or to friction. The present understanding of the whole menagerie of slip patterns is based upon numerical simulations imposing ad hoc values of the rate and state parameters a and b4-6 derived from the temperature dependence of a and b of a wet granite gouge7. Here we investigate the influence of the cumulative slip on the frictional and acoustic patterns of a lab scale subduction zone. Shallow loud earthquakes (stick-slip events), medium depth slow, deeper silent quakes (smooth sliding oscillations) and deepest steady-state creep (continuous sliding) are reproduced by the ageing of contact interface with cumulative displacement8. The Acoustic Emission evolves with cumulative displacement and interface ageing, following a trend from strong impulsive events, similar to earthquake seismic signals, to a collection of smaller amplitude and longer duration signals, similar to Non Volcanic Tremors. NVT emerge as the recollection of the local unstable behaviour of the contact interface globally evolving towards the stable sliding regime.

description: The magneto-optic Kerr effect is a powerful tool for measuring magnetism in thin films at microscopic scales, as was recently demonstrated by the major role it played in the discovery of two-dimensional (2D) ferromagnetism in monolayer CrI$_3$ and Cr$_2$Ge$_2$Te$_6$. These 2D magnets are often stacked with other 2D materials in van der Waals heterostructures on a SiO$_2$/Si substrate, giving rise to thin-film interference. This can strongly affect magneto-optical measurements, but is often not taken into account in experiments. Here, we show that thin-film interference can be used to engineer the magneto-optical signals of 2D magnetic materials and optimize them for a given experiment or setup. Using the transfer matrix method, we analyze the magneto-optical signals from realistic systems composed of van der Waals heterostructures on SiO$_2$/Si substrates, using CrI$_3$ as a prototypical 2D magnet, and hexagonal boron nitride (hBN) to encapsulate this air-sensitive layer. We observe a strong modulation of the Kerr rotation and ellipticity, reaching several tens to hundreds of milliradians, as a function of the illumination wavelength, and the thickness of the SiO$_2$ and layers composing the van der Waals heterostructure. Similar results are obtained in heterostructures composed by other 2D magnets, such as CrCl$_3$, CrBr$_3$ and Cr$_2$Ge$_2$Te$_6$. Designing samples for the optimal trade-off between magnitude of the magneto-optical signals and intensity of the reflected light should result in a higher sensitivity and shorter measurement times. Therefore, we expect that careful sample engineering, taking into account thin-film interference effects, will further the knowledge of magnetization in low-dimensional structures.

description: At present, people are experiencing a slew of medical issues due to poor dietary habits. It is very importantto understand how the foods and beverages they consume affect their future health. People will be able toavoid unhealthy eating habits if there is a way to determine how healthy their diet is and what diseasesthey may get in the future as a result of the foods they eat. The grocery list is a key factor to get an idea ofthe foods and beverages that people consume. In this research, novel approaches are introduced to detectand predict the future diseases of the respective grocery list users by analyzing the amount of nutrients likeprotein, carbs, fat, and fiber in the grocery list. The research consists of a mobile application that uses atrained machine learning model to predict diseases. The system is capable of predicting three specificdiseases, namely high blood pressure, cholesterol, and diabetes. The results obtained show that a highaccuracy of 84% on Decision Tree model. Th proposed system is incredibly useful for users, as they canbe aware of the risk of contracting diseases and take appropriate measures to prevent those diseases. Userscan get many benefits such as eliminating health disparities, saving money and improving quality of life.
Dark Matter Halo Profiles in Scale-Free Cosmologies

description: We explore the dependence of the central logarithmic slope of dark matter halo density profiles $α$ on the spectral index $n$ of the linear matter power spectrum $P(k)$ using cosmological $N$-body simulations of scale-free models (i.e. $P(k) \propto k^n$). For each of our simulations we identify samples of well resolved haloes in dynamical equilibrium and we analyse their mass profiles. By parameterising the mass profile using a ``generalised'' Navarro, Frenk & White profile in which the central logarithmic slope $α$ is allowed to vary while preserving the $r^{-3}$ asymptotic form at large radii, we obtain preferred central slopes for haloes in each of our models. There is a strong correlation between $α$ and $n$, such that $α$ becomes shallower as $n$ becomes steeper. However, if we normalise our mass profiles by $r_{-2}$, the radius at which the logarithmic slope of the density profile is -2, we find that these differences are no longer present. We conclude that there is no evidence for convergence to a unique central asymptotic slope, at least on the scales that we can resolve.
