description: An international trade model which explains trade patterns of processed foods relative to textiles using relative technological change and relative factor endowments was developed. This model was tested in the case of the United States and a number of ASEAN countries. Results indicate that exogenous technology drives the trade pattern of the Asian Newly Industrializing Countries (NICs) while endogenous technology drives the trade patterns of the lesser developed ASEAN countries. Significant determinants of endogenous technology were identified: foreign aid flows, research and development expenditures, and market power. Two significant issues were raised in the course of the analysis: (1) the effectiveness of U.S. foreign aid package in developing the United States and the ASEAN countries' agri-based manufacturing industries, and (2) the evolution of the high growth Asian NICs and their impact on the lesser developed ASEAN countries.

description: A cluster analysis based on a five-year growth rate of agricultural imports from the United States was conducted on 86 countries and revealed two significant market segments for U.S. agriculture: the high-growth markets and the low-growth markets. Multiple discriminant analysis was then used to test the significance of the countries' trade-related and macroeconomic variables to their market growth classification. The discriminant function was used to predict the high-growth markets for U.S. agriculture in 1994. High-growth markets for U.S. agriculture exhibit faster GDP and agricultural import growth rates, are relatively agriculturally self-sufficient, and are near the United States. On the other hand, low-growth markets exhibit slower GDP and agricultural import growth rates, and are geographically distant from the United States.

description: „Fridays For Future“ ist eine globale soziale Bewegung von SchülerInnen und StudentInnen, welche sich für den Klimaschutz, insbesondere für die Einhaltung der Ziele des Pariser Klimaabkommens und des 1,5 º C-Ziels einsetzen. An Freitagen verweigern sie den Schul- bzw. Universitätsbesuch und demonstrieren öffentlich. Auf selbstgemachten Demonstrations-Plakaten drücken sie sich zum größten Teil metaphorisch aus. Es scheint, als wirken Vorstellungen über eine derzeitige und zukünftige Bedrohung mit einer gewissen Strahlkraft auf die metaphorischen Problembeschreibungen. Diese Arbeit analysiert die verwendeten Metaphern systematisch. Welche Aspekte werden durch die Metaphern besonders hervorgehoben, welche ausgegrenzt? Ziel ist es, mögliche Logiken im Umgang mit dem Klimawandel zu erkennen. Gleichzeitig ist diese Arbeit ein Versuch, die Relevanz von Metaphern für zukunftsorientiertes Forschen hervorzuheben. Neben einer theoretischen Beschreibung unterschiedlicher Methaphernarten zeigt die Arbeit den Einfluss von Metaphern auf Denken, Wahrnehmung und Handeln auf.

description: Scanner data for breakfast cereals are used to estimate demand elasticities for six supermarket stores in two distinct socio-economic areas. Three stores are in low-income locations and three are in high-income locations. A time series cross-section model is estimated for five product categories across six cross sections over forty-two weeks. Results show lower-income shoppers to have more elastic demands for four of the five product categories: private label cold cereals, the top ten brands of cold cereals, all other brands of cold cereals, and hot cereals. Price is not statistically significant for a fifth product category, snack cereals.

description: We model the dynamics of point Josephson junctions in a 1D microstrip line using a wave equation with delta distributed sine nonlinearities. The model is suitable for both low T$_c$ and high T$_c$ systems (0 and $π$ junctions). For a single junction in the line, we found two limiting behaviors: the ohmic mode where the junction acts as a pure resistor which stops waves and separates the cavity and the junction mode where the wave is homogeneous throughout the strip. This classification allows to bound the IV curves of the system. Two junctions in a strip give generally ohmic modes and combined junction/ohmic modes and yield information about the behavior with an array with many junctions. Finally we use this analysis to understand the many junction case for 0 and $π$ junctions and the effect of an external magnetic field.

description: Η πανδημία των τελευταίων ετών επέφερε ξαφνικές αλλαγές στην καθημερινότητα των ανθρώπων, με συνέπεια το σταμάτημα της κανονικότητας της εκπαιδευτικής δράσης σε παγκόσμιο και εθνικό επίπεδο. Η εξ αποστάσεως εκπαίδευση έκτακτης ανάγκης, είτε όπως καλείται διαφορετικά η τηλεκπαίδευση, αποτέλεσε τη μοναδική λύση με στόχο τη συνέχιση της εκπαίδευσης των παιδιών από το σπίτι κατά την περίοδο της πανδημίας στη χώρα μας. Οι εκπαιδευτικοί κλήθηκαν να συνεχίζουν τις δράσεις τους μέσα στα καινούρια δεδομένα και να αποκαταστήσουν άμεσα την επικοινωνία με την αξιοποίηση της εξ αποστάσεως εκπαίδευσης, για την οποία, όμως, οι περισσότεροι στη χώρα μας δεν ήταν εξοικειωμένοι. Κλήθηκαν, επομένως, να αντιμετωπίσουν σημαντικές προκλήσεις, όπως ήταν για παράδειγμα τα διαφοροποιημένα επίπεδα ψηφιακών ικανοτήτων, ο μη επαρκής τεχνολογικός εξοπλισμός, καθώς επίσης και η τεράστια έλλειψη προσβασιμότητας σε αυτή την εκπαιδευτική δράση είτε ακόμα και η μη επαρκής επιμόρφωση σχετικά με αυτό το ζήτημα. Στόχος της συγκεκριμένης τακτικής ήταν να διευκολυνθεί και πάλι η επικοινωνία μεταξύ του εκπαιδευτικού κόσμου και να συνεχιστεί κατά κάποιον τρόπο η μαθησιακή δράση. Δεν θα πρέπει να ξεχνάμε πως τα τελευταία χρόνια έρευνες αναφέρουν πως η τηλεκπαίδευση αποτελεί την καταλληλότερη εκπαιδευτική τακτική μετά τη δια ζώσης διδασκαλία. Η εφαρμογή της εν λόγω εκπαιδευτικής δράσης έφερε και πάλι στην επιφάνεια τη συζήτηση για τις εκπαιδευτικές ανισότητες στις σύγχρονες σχολικές μονάδες, αφού αρκετά παιδιά δεν είχαν τα απαιτούμενα εφόδια για να συμμετέχουν σε μια τέτοια δράση. Κυριότερος στόχος της εν λόγω εργασίας είναι η μελέτη των αντιλήψεων των εκπαιδευτικών πρωτοβάθμιας εκπαίδευσης σε ό,τι έχει να κάνει με τον τρόπο δράσης της εξ αποστάσεως εκπαίδευσης στη χώρα μας κατά την περίοδο της πανδημίας, τα προβλήματα τα οποία υπήρξαν, καθώς επίσης και τη σχέση της αποδοτικότητας αυτής της εκπαιδευτικής δράσης με τα κοινωνικά και οικονομικά γνωρίσματα των παιδιών.

description: State governments are concerned with economic development because the condition of their well being determines residents' standard of living. Therefore, state governments are interested in strategies for strengthening their economies. States with substantial agricultural production can implement a strategy of maintaining or increasing markets for that production, positively affecting all of the aforementioned measures. In some states, the focus has been to "add value" to raw agricultural commodities. Texas's food processing industry is the focus of this research. A survey was conducted to determine the cost components of Texas food processors, the percent of purchases from Texas, and reasons for these purchases. This article summarizes the results of this survey.

description: We consider the scenario in which neutrino data are explained by the interplay of type I and II seesaw terms in the Majorana neutrino mass matrix ${\cal M}_ν= {\cal M}_L - {\cal M}_D {\cal M}_R^{-1} {\cal M}_D^T$. We construct a predictive model with ${\cal M}_L$ proportional to the unit matrix, 3 diagonal texture zeros in ${\cal M}_R$, and ${\cal M}_D$ diagonal. We show how this pattern can be maintained by the non-Abelian discrete symmetry $A_4$, and discuss its phenomenological consequences. It turns out that the two types of seesaw give contributions of the same order to ${\cal M}_ν$. In the CP conserving case, we find $\sinθ_{13}\approx 2/(\tan 2θ_{23} \tan 2θ_{12})$ and we predict inverted (normal) ordering of the mass spectrum for $\tan^2θ_{12} < 0.5 ~(>0.5)$.

description: We find that the minor axes of the ultra-diffuse galaxies (UDGs) in Abell 2634 tend to be aligned with the major axis of the central dominant galaxy, at a $\gtrsim 95\%$ confidence level. This alignment is produced by the bright UDGs with the absolute magnitudes $M_r0.5R_{200}$. The alignment signal implies that these bright, outer-region UDGs are very likely to acquire their angular momenta from the vortices around the large-scale filament before they were accreted into A2634, and form their extended stellar bodies outside of the cluster; in this scenario, the orientations of their primordial angular momenta, which are roughly shown by their minor axes on the images, should tend to be parallel to the elongation of the large-scale filament. When these UDGs fell into the unrelaxed cluster A2634 along the filament, they could still preserve their primordial alignment signal before violent relaxation and encounters. These bright, outer-region UDGs in A2634 are very unlikely to be the descendants of the high-surface-brightness dwarf progenitors under tidal interactions with the central dominant galaxy in the cluster environment. Our results indicate that the primordial alignment could be a useful probe of the origin of UDGs in large-scale structures.

description: Famous non-Fermi liquid-like behaviors of the transport phenomena in high-Tc cuprates (Hall coefficient, magnetoresistance, thermoelectric power, Nernst coefficient, etc) are caused by the current vertex corrections in neary antiferromagnetic (AF) Fermi liquid, which was called the backflow by Landau. We present a simple explaination why the backflow is prominent in strongly correlated systems. In nearly AF Fermi liquid, R_H is enhanced by the backflow because it changes the effective curvature of the Fermi surfaces. Therefore, the relaxation time approximation is not appricalbe to a system near a magnetic quantum critical point (QCP).

description: Carbonates are highly heterogeneous formations with large variations in pore size distribution and pore space topology, which results in complex multiphase flow behavior. Here we investigate the spontaneous imbibition behavior of fluids in vuggy carbonates. Glass beads of 1.0 mm diameter, with dissolvable inclusions, are sintered to form multiple configurations of heterogeneous vuggy core with variations in matrix porosity, vug size, vug spatial location, and number of vugs. The core fabrication process is repeatable and allows the impact of vug textural properties to be investigated in a controlled manner. Capillary rise experiments are conducted in these proxy vuggy carbonate core and compared with the homogeneous non-vuggy core as reference. Continuous optical imaging is performed to track the position of the air-water interface in the cores. To understand the change in capillary height in the presence of a vug, a volume-of-fluid two-phase numerical simulation is performed in a parallel set of connected and disconnected tubes. Finally x-ray tomography scans are performed to identify the shape of the air-water interface in a select few cores. The results can be summarized as follows: disconnected vugs result in higher capillary rise compared to non-vuggy porous media. The vugs act as capillary barriers, diverting fluid flow to the adjacent connected channels, which ultimately results in a higher overall capillary rise. The results of this work highlight that radius of spontaneous invasion of aqueous phases, such as fracture fluid and hazardous wastes, are affected by vug porosity but not their distribution.

description: This exploratory research looks at the role of capital expenditures in the food manufacturing industries in the face of industry productivity changes and industry restructuring. Food processing's position as the economy's largest manufacturing industry in shipments is compared with its share of total capital expenditures. Gross capital stock, net capital stock, gross constant stock, and net constant stock are examined to estimate changing capital base. Rates of change in multifactor and output per man hour productivity are compared with rates of change in new capital expenditures. Major industrial reorganization has taken place in food processing because of mergers, acquisitions, and leveraged buyouts. The change in capital expenditures following these transactions is examined to determine their impact on industry investment.

Performance evaluations of wireless Internet access using the Wireless Applications Protocol
Creators: name: Sheoran, Shailesh
Publisher: name: University of British Columbia

description: The popular Internet protocol stack, TCP/IP, is not suitable for low bandwidth, high latency wireless channels. Problems associated with TCP's throughput in wireless conditions has necessitated the development of alternative protocols that can provide efficient means of transmitting Internet content over a wireless network. Wireless Applications Protocol (WAP) is one such alternative to using TCP/IP for accessing Internet services over wireless channels. In this thesis, the performance of two different WAP network configurations, one being more secure than the other is evaluated and compared under varying Internet and wireless conditions. Effect of asymmetric conditions is also studied. Possibility of providing WAP services over wireless bearers with no error recovery Link Layer is also evaluated experimentally. Simulations indicate that the secure configuration, termed as the alternate configuration (AC), has a better performance than non-secure standard configuration (SC) for good (1% FER) and average (6% FER) wireless conditions. SC has better performance on bad wireless conditions (44% FER, <1000 bps throughput). Performance of AC is affected primarily by wireless conditions whereas performance of SC is affected primarily by Internet conditions. Primary factor that degrades AC's performance is flooding of the wireless channel by redundant reply packets from the server end causing long waiting times on the wireless channel queues. Additionally, under bad wireless conditions, if there is asymmetry present on the channel, AC is unusable. SC's performance degrades under degraded (congested) Internet conditions because TCP's employs congestion avoidance mechanisms and reduces its throughput on detecting congestion on the Internet. Another result of consequence is that under good and average wireless and Internet conditions, presence of the error recovery Link Layer has minimal effect on performance of AC and SC. Some solutions to cushion effect of bad wireless conditions on AC's performance are proposed and tested. The solutions proposed are the use of duplicate packet filtering at link layer level and use of larger reply timers and gradually increasing timers at the WAP gateway. First solution is not employable if data decryption is used. The other two gateway end solutions improve AC's performance under bad wireless conditions but decrease its performance under good and average wireless conditions. This leads to the conclusion that better flow control mechanisms are needed in WTP such that the traffic generation (of retransmissions) at the server is sensitive to conditions on the wireless channel.

description: Einstein gravitation theory can be extended by preserving its geometrical nature but changing the relation between curvature and energy-momentum tensors. This change accounts for radiative corrections, replacing the Newton gravitation constant by two running couplings which depend on scale and differ in the two sectors of traceless and traced tensors. The metric and curvature tensors in the field of the Sun, which were obtained in previous papers within a linearized approximation, are then calculated without this restriction. Modifications of gravitational effects on geodesics are then studied, allowing one to explore phenomenological consequences of extensions lying in the vicinity of general relativity. Some of these extended theories are able to account for the Pioneer anomaly while remaining compatible with tests involving the motion of planets. The PPN Ansatz corresponds to peculiar extensions of general relativity which do not have the ability to meet this compatibility challenge.

description: The linear conductance of a molecular conductor oscillating between two metallic leads is investigated numerically both for Hubbard interacting and noninteracting electrons. The molecule-leads tunneling barriers depend on the molecule displacement from its equilibrium position. The results present an interesting interference which leads to a conductance dip at the electron-hole symmetry point, that could be experimentally observable. It is shown that this dip is caused by the destructive interference between the purely electronic and phonon-assisted tunneling channels, which are found to carry opposite phases. When an internal vibrational mode is also active, the electron-hole symmetry is broken but a Fano-like interference is still observed.

As a result 85 compounds, representing 87.9-99.2% of the detected compounds, were identified by GC/MS and simultaneously quantified by GC-FID.The main aroma constituents in the essential oil sampleswere monoterpene alcohols citronellol (20.8-30.8%), geraniol (19.3-23.3%) and nerol (8.9-10.8%), followed by the stearopten fraction with nonadecane (12.0-17.5%), nonadecene (1.0-4.0%), heneicosane (4.0-5.8%) and heptadecane (1.8-2.5%) found in highest concentration. The chemical composition of the extracts was dominated by b-phenylethyl alcohol - 56.6% found in the subcritical sample and 46.7% in the supercritical one. Fatty acids esters, waxes and triterpenoids were found in the extracts as well. In addition, sensory evaluation of the rose aroma products was performed, demonstrating intense citrus, floral and balsamic notes for the essential oils and slight herbaceous and fruity notes for the extracts.

description: We study dynamical ordering of rods. In this process, rod alignment via pairwise interactions competes with diffusive wiggling. Under strong diffusion, the system is disordered, but at weak diffusion, the system is ordered. We present an exact steady-state solution for the nonlinear and nonlocal kinetic theory of this process. We find the Fourier transform as a function of the order parameter, and show that Fourier modes decay exponentially with the wave number. We also obtain the order parameter in terms of the diffusion constant. This solution is obtained using iterated partitions of the integer numbers.

description: I present new results on the quark distribution in an on-shell heavy quark in perturbative QCD and explore its all-order relations with heavy-quark fragmentation. I first compute the momentum distribution function to all orders in the large-beta_0 limit and show that it is identical to the perturbative heavy-quark fragmentation function in the same approximation. I then analyze the Sudakov limit of the distribution and the fragmentation functions using Wilson lines and prove that the corresponding Sudakov exponents in the non-Abelian theory are the same to any logarithmic accuracy. The anomalous dimension is then determined to two-loop order, corresponding to next-to-next-to-leading logarithmic accuracy in the exponent, in two ways: the first by extracting the singular terms from a recent calculation of the fragmentation function and the second by performing the two-loop Wilson-line calculation in configuration space. I find perfect agreement between the two.

description: The demand for food away from home, food at home, and non-food items is investigated using a complete systems approach. Using the linear approximation of the dynamic version of the Almost Ideal Demand System, the results indicate that the share of total expenditure going to food away from home increases as the labor force participation rate of women increases. All expenditure elasticities are positive and all own-price elasticities are negative. Moreover, the demand for food away from home is more price sensitive than the demand for food at home. Seasonal patterns of consumption are also evident.

description: We present results from Atacama Large Millimeter/submillimeter Array (ALMA) observations of CS from the nearby galaxy NGC 1068 ($\sim14$ Mpc). This Seyfert 2 barred galaxy possesses a circumnuclear disc (CND, $r\sim200$ pc) and a starburst ring (SB ring, $r\sim1.3$ kpc). These high-resolution maps ($\sim0.5$", $\sim35$ pc) allow us to analyse specific sub-regions in the galaxy and investigate differences in line intensity ratios and physical conditions, particularly those between the CND and SB ring. Local thermodynamic equilibrium (LTE) analysis of the gas is used to calculate CS densities in each sub-region, followed by non-LTE analysis conducted using the radiative transfer code RADEX to fit observations and constrain gas temperature, CS column density and hydrogen density. Finally, the chemical code UCLCHEM is used to reconstruct the gas, allowing an insight into its origin and chemical history. The density of hydrogen in the CND is found to be $\geq10^5$ cm$^{-2}$, although exact values vary, reaching $10^6$ cm$^{-2}$ at the AGN. The conditions in the two arms of the SB ring appear similar to one another, though the density found ($\sim10^4$ cm$^{-2}$) is lower than in the CND. The temperature in the CND increases from east to west, and is also overall greater than found in the SB ring. These modelling methods indicate the requirement for multi-phase gas components in order to fit the observed emission over the galaxy. A larger number of high resolution transitions across the SLED may allow for further constraining of the conditions, particularly in the SB ring.

We compare several existing methods for removing such systematics from galaxy clustering measurements. We show how all the methods, including the popular pseudo-$C_\ell$ Mode Projection and Template Subtraction methods, can be interpreted under a common regression framework and use this to suggest improved estimators. We show how methods designed to mitigate systematics in the power spectrum can be used to produce clean maps, which are necessary for cosmological analyses beyond the power spectrum, and we extend current methods to treat the next-order multiplicative contamination in observed maps and power spectra. Two new mitigation methods are proposed, which incorporate desirable features of current state-of-the-art methods while being simpler to implement. Investigating the performance of all the methods on a common set of simulated measurements from Year 5 of the Dark Energy Survey, we test their robustness to various analysis cases. Our proposed methods produce improved maps and power spectra when compared to current methods, while requiring almost no user tuning. We end with recommendations for systematics mitigation in future surveys, and note that the methods presented are generally applicable beyond the galaxy distribution to any field with spatial systematics.

description: This study estimates demand during the 1980-90 period for wholesale beef cuts by season and by trend. A data set containing monthly nominal prices for wholesale cuts and average choice boxed beef from January 1980 to December 1990 was collected from multiple sources. The approach expressed the change in demand for wholesale cuts as the change in the price ratio of individual cuts relative to the price of boxed beef. This approach shows changes in amount by season and over time relative to the average wholesale cut. Brisket, Armbone Chuck, Bottom Gooseneck, and Knuckle showed the strongest demand in winter and lowest in summer. Top (Inside) Round had a clear downward trend in demand, but the seasonal pattern was less pronounced and more erratic than the lower-priced cuts. Top Sirloin Butt had its highest demand in spring and summer with November-December being the lowest period. Strip Loin had the strongest warm season demand during the period which contains Memorial Day. Ribeye experienced a seasonal demand highest in November-December and lowest in January to April. Full Tenderloin was the most expensive wholesale beef cut analyzed in the study, and its demand was highest in November-December. The study clearly showed that a change in seasonal demand was responsible for the major part of price ratio fluctuations for individual wholesale cuts.

description: Federal and state governments operate inspection systems to help assure consumers of the wholesomeness and cleanliness of food products. Each major outbreak of human illness attributed to foodborne pathogens or to cancer-causing residues in foods raises questions as to the effectiveness of this food inspection. How do food store managers and consumers differ in their perceptions of needed food inspection? Mail surveys of households and food stores in three urban and five rural Louisiana parishes in 1992 provided data on consumer perceived inspection requirements for domestically processed seafood, imported seafood and red meats, and for maximum permissible content of cancer-causing substances.

description: The K2 mission of the Kepler Space Telescope offers a unique possibility to examine sources of both Galactic and Extra-galactic origin with high cadence photometry. Alongside the multitude of supernovae and quasars detected within targeted galaxies, it is likely that Kepler has serendipitously observed many transients throughout K2. Such events will likely have occurred in background pixels, coincidentally surrounding science targets. Analysing the background pixels presents the possibility to conduct a high cadence survey with areas of a few square degrees per campaign. We demonstrate the capacity to independently recover key K2 transients such as KSN 2015K and SN 2018oh. With this survey, we expect to detect numerous transients and determine the first comprehensive rates for transients with lifetimes $\leq1$ day.

title: Speech Spectral Modeling and Speech Synthesis Using Finite Impulse Response Digital Filters
Creators: name: Gordy, Paul Edward
Publisher: name: Old Dominion University Libraries
Year: 1982

description: Synthetic speech can be produced using a discrete-time model of human speech production. This model depends on the use of digital filters to model the spectral characteristics of the vocal tract. Speech spectra can be efficiently encoded using a set of principal components basis vectors; however, these vectors are not in a convenient mathematical form for directly determining a digital filter for the speech production model. If discrete cosine basis vectors are used to approximate the principal components basis vectors, then the cosine basis vector coefficients can be used to determine a Finite Impulse Response(FIR) digital filter for speech spectral modeling and speech synthesis. Three FIR filter formulations are presented and the corresponding analysis/synthesis systems are implemented on a digital computer. These formulations vary in terms of phase, spectral amplitude and frequency scaling, and computational complexity. The FIR analysis/synthesis systems are compared with the analysis/synthesis systems based on the principal components basis vectors and linear predictor filters(Infinite Impulse Response filters). A sentence preference test is used to compare the various systems. The results of the tests indicate that FIR digital filters can be used to produce high quality synthetic speech.

description: We propose to identify the new "intermediate" morphology in subsaturation nuclear matter observed in a recent quantum molecular dynamics simulation with the ordered bicontinuous double-diamond structure known in block copolymers. We estimate its energy density by incorporating the normalized area-volume relation given in a literature into the nuclear liquid drop model. The resulting energy density is higher than the other five known morphologies.

description: We propose a new framework for constructing geometric and physical models on nonholonomic manifolds provided both with Clifford -- Lie algebroid symmetry and nonlinear connection structure. Explicit parametrizations of generic off-diagonal metrics and linear and nonlinear connections define different types of Finsler, Lagrange and/or Riemann-Cartan spaces. A generalization to spinor fields and Dirac operators on nonholonomic manifolds motivates the theory of Clifford algebroids defined as Clifford bundles, in general, enabled with nonintegrable distributions defining the nonlinear connection. In this work, we elaborate the algebroid spinor differential geometry and formulate the (scalar, Proca, graviton, spinor and gauge) field equations on Lie algebroids. The paper communicates new developments in geometrical formulation of physical theories and this approach is grounded on a number of previous examples when exact solutions with generic off-diagonal metrics and generalized symmetries in modern gravity define nonholonomic spacetime manifolds with uncompactified extra dimensions.

Motion of the hydrogen bond proton in cytosine and the transition between its normal and imino states

description: The potential energy surface of the H13 proton in base cytosine of the DNA molecules is calculated {\it ab initio} at the Gaussian98 MP2/6-311G(d,p) level. Two potential wells are found. One corresponds to the normal cytosine, while the other corresponds to its imino tautomer. The bindings of the proton in these wells are stable enough against the thermo-disturbance. The motions of the proton in these wells are oscillations around the nearest nitrogen atom like the pendula, and may move far away from the nitrogen atom to form the hydrogen bond with other bases. The estimated tunneling probability of the H13 proton from one well to another well shows that the life time of the proton staying in one of these wells is about 6$\times10^2$ yr. It is too long to let tautomers of cytosine be in thermodynamical equilibrium in a room temperature gas phase experiment. The biological significance of these result is discussed.

description: This article examines the impact of socio-demographic factors on individual consumption of alcohol in the United States using the Heckman procedure and logit analysis. Factors considered are urbanization, race, ethnicity, region, weight, height, sex, food stamp participation, employment status, diet status, day of consumption, household size, age, and income. All the variables, with the exception of ethnicity and food stamp participation, significantly influence the decision to consume alcohol. Results also indicate that urbanization, region, sex, food stamp participation, and household size significantly affect the level of alcohol consumption.

description: We investigate the on-average properties for 28 star-forming ultra-diffuse galaxies (UDGs) located in low-density environments, by stacking their spectra from the Sloan Digital Sky Survey. These relatively-isolated UDGs, with stellar masses of $\log_{10}(M_*/M_{\odot})\sim 8.57\pm0.29$, have the on-average total-stellar-metallicity [M/H]$\sim -0.82\pm0.14$, iron-metallicity [Fe/H]$\sim -1.00\pm0.16$, stellar age $t_*\sim5.2\pm0.5$ Gyr, $α$-enhancement [$α$/Fe]$\sim 0.24\pm0.10$, and oxygen abundance 12+log(O/H)$\sim 8.16\pm0.06$, as well as central stellar velocity dispersion $54\pm12$ km/s. On the star-formation rate versus stellar mass diagram, these UDGs are located lower than the extrapolated star-forming main sequence from the massive spirals, but roughly follow the main sequence of low-surface-brightness dwarf galaxies. We find that these star-forming UDGs are not particularly metal-poor or metal-rich for their stellar masses, as compared with the metallicity-mass relations of the nearby typical dwarfs. With the UDG data of this work and previous studies, we also find a coarse correlation between [Fe/H] and magnesium-element enhancement [Mg/Fe] for UDGs: [Mg/Fe]$\simeq-0.43(\pm0.26)$[Fe/H]$-0.14(\pm0.40)$.
