description: Elliptic flow measurements are presented and discussed with emphasis on the hydrodynamic character of the hot and dense QCD matter created in heavy ion collisions at RHIC. Predictions from perfect fluid hydrodynamics for the scaling of the elliptic flow coefficient $v_2$ with eccentricity, system size and transverse energy are validated. A universal scaling for the flow of both mesons and baryons is observed for a broad transverse kinetic energy range when quark number scaling is employed. This suggests a new state of nuclear matter at extremely high density and temperature whose primary constituents have the quantum numbers of quarks and anti-quarks in chemical equilibrium. The scaled flow is used to constrain estimates for several transport coefficients including the sound speed $c_s$, shear viscosity to entropy ratio $η/s$, diffusion coefficient ($D_c$) and sound attenuation length ($Γ$). The estimated value $η/s \sim 0.1$, is close to the absolute lower bound ($1/4π$), and may signal thermodynamic trajectories for the decaying matter which lie close to the QCD critical end point.

description: After crossing an initial barrier to break the first base-pair (bp) in double-stranded DNA, the disruption of further bps is characterized by free energies between less than one to a few kT. This causes the opening of intermittent single-stranded bubbles. Their unzipping and zipping dynamics can be monitored by single molecule fluorescence or NMR methods. We here establish a dynamic description of this DNA-breathing in a heteropolymer DNA in terms of a master equation that governs the time evolution of the joint probability distribution for the bubble size and position along the sequence. The transfer coefficients are based on the Poland-Scheraga free energy model. We derive the autocorrelation function for the bubble dynamics and the associated relaxation time spectrum. In particular, we show how one can obtain the probability densities of individual bubble lifetimes and of the waiting times between successive bubble events from the master equation. A comparison to results of a stochastic Gillespie simulation shows excellent agreement.

description: Testing for causality between events in distributed executions is a fundamental problem. Vector clocks solve this problem but do not scale well. The probabilistic Bloom clock can determine causality between events with lower space, time, and message-space overhead than vector clock; however, predictions suffer from false positives. We give the protocol for the Bloom clock based on Counting Bloom filters and study its properties including the probabilities of a positive outcome and a false positive. We show the results of extensive experiments to determine how these above probabilities vary as a function of the Bloom timestamps of the two events being tested, and to determine the accuracy, precision, and false positive rate of a slice of the execution containing events in the temporal proximity of each other. Based on these experiments, we make recommendations for the setting of the Bloom clock parameters. We postulate the causality spread hypothesis from the application's perspective to indicate whether Bloom clocks will be suitable for correct predictions with high confidence. The Bloom clock design can serve as a viable space-, time-, and message-space-efficient alternative to vector clocks if false positives can be tolerated by an application.

description: The $\ge73m$ metastable states decay with a very characteristic signature which allow them to be tagged event-by-event. Studies were performed using data taken with a high-purity germanium detector in a low-background laboratory near a nuclear power reactor core where $\nuebar$-flux was $\rm{6.4 \times 10^{12} ~ cm^{-2} s^{-1}}$. The measured average and equilibrium production rates of $\ge73m$ were $\rm{(8.7 \pm 0.4)}$ and $\rm{(6.7 \pm 0.3) ~ kg^{-1} day^{-1}}$, respectively. The production channels were studied and identified. By studying the difference in the production of $\ge73m$ between the reactor ON and OFF spectra, the limiting sensitivities at the range of $\rm{\sim 10^{-42} - 10^{-43} ~ cm^2}$ for the cross-sections of neutrino-induced nuclear transitions were derived. The dominant background are due to $β$-decays of cosmic-ray induced $^{73}$Ga. The prospects of enhancing the sensitivities at underground locations are discussed.

Εξετάζεται αρχικά ο βασικός κορμός της πλατωνικής σκέψης και συγκεκριμένα η διάκριση του Πλάτωνα στον κόσμο των ιδεών σε αντιδιαστολή προς τον κόσμο των αισθήσεων. Γίνεται αναφορά πώς αξιοποιεί ο Πλάτων την αντίθεση της ηρακλείτειας φιλοσοφίας προς την σκέψη του Παρμενίδη. Έπειτα γίνεται λόγος για τη θεωρία του Πλάτωνα σχετικά με την υπόθεση ότι η γνώση είναι ανάμνηση. Εξετάζονται οι πλατωνικοί διάλογοι Μένων, Φαιδρός, Φαίδων, Πολιτεία και Συμπόσιο. Με τη μελέτη αυτών των διαλόγων ερευνάται ο τρόπος με τον οποίο αντιμετώπιζε ο Πλάτων τη θεωρία της ανάμνησης.
description: The aim of this thesis was the question of knowledge as recollection in the Plato's philosophy. Initially we examined the basic trunke of Plato's thought and concretely the discrimination of Plato to the world of ideas in contradiction to the world of senses. It is also explicated the way that Plato develops backs the opposition of Heraclitus' philosophy and thought of Parmenides. Another point is the Plato's theory about the affair that the knowledge is recollection. The examined dialogues are Meno, Faedrus, Fhaedo, Republic, and Symposium. The study of these dialogues can explicate the Plato's theory of recollection.
Pseudo-Adaptive Penalization to Handle Constraints in Particle Swarm Optimizers

description: The penalization method is a popular technique to provide particle swarm optimizers with the ability to handle constraints. The downside is the need of penalization coefficients whose settings are problem-specific. While adaptive coefficients can be found in the literature, a different adaptive scheme is proposed in this paper, where coefficients are kept constant. A pseudo-adaptive relaxation of the tolerances for constraint violations while penalizing only violations beyond such tolerances results in a pseudo-adaptive penalization. A particle swarm optimizer is tested on a suite of benchmark problems for three types of tolerance relaxation: no relaxation; self-tuned initial relaxation with deterministic decrease; and self-tuned initial relaxation with pseudo-adaptive decrease. Other authors' results are offered as frames of reference.

description: The Freight Movement and Intermodal Access in Kentucky Study (SPR 98-189), undertaken by the Kentucky Transportation Center (KTC) on behalf of the Kentucky Transportation Cabinet (KYTC), has two main objectives. These objectives include 1) the evaluation of access for trucks between intermodal or other truck generating sites and the National Highway System (NHS) and 2) furthering the understanding of freight commodity flows throughout the state. This report summarizes the access evaluation for one facility located in Henry County in the KIPDA Area Development District (ADD) and KYTC Highway District #5. The location of the site is shown in Figure 1. Work on other specific sites as well as the freight commodity flow task are on-going and are documented elsewhere.  The sites to be evaluated were selected from two existing databases (a truck facility survey from 1994 and the intermodal facility inventory) based on ADD and KYTC Highway District planner recommendations, geographic location, distance to the NHS, and the number of trucks accessing the site. Consideration was also made for the freight type handled and transportation modes used.  The facility for study in this report is Safety Kleen in Smithfield, and the initial trip to the site revealed that there were no other significant sources of truck traffic in the vicinity. The site was visited for video recording on March 5, 1998 and the initial site visit for data collection was on July 3, 1998. Traffic counts were conducted by Presnell Associates for the KYTC Division of Planning between July 27 and July 29, 1998. Early into the study process, phone surveys were conducted so that facility managers could indicate the routes used by trucks and provide insight into potential access-limiting issues. The phone survey completed with this facility, which is found in Appendix A, indicated that approximately 60 trucks per day (120 one-way trips) are accessing the facility.

description: We present precise z-band photometric time series spanning times of transit of the two exoplanets recently discovered by the SuperWASP collaboration. We find planetary radii of 1.44 +/- 0.08 R_J and 1.04 +/- 0.06 R_J for WASP-1b and WASP-2b, respectively. These error estimates include both random errors in the photometry and also the uncertainty in the stellar masses. Our results are 5 times more precise than the values derived from the discovery data alone. Our measurement of the radius of WASP-2b agrees with previously published models of hot Jupiters that include both a 20-M_Earth core of solid material and the effects of stellar insolation. In contrast, we find that the models cannot account for the large size of WASP-1b, even if the planet has no core. Thus, we add WASP-1b to the growing list of hot Jupiters that are larger than expected. This suggests that ``inflated'' hot Jupiters are more common than previously thought, and that any purported explanations involving highly unusual circumstances are disfavored.

Are you impaired? : Developing a task sensitive to the impairing effects of alcohol and drugs using a combined compensatory tracking and dual attention task
Creators: name: Vuister, Josef
Publisher: name: University of Tasmania
Year: 2024

description: As the use of prescription cannabis, psychiatric medications, and new psychoactive substances increases, concerns have been raised over how best to assess drug intoxication, particularly since there are no consistent biological markers of impairment for substances such as cannabis. Subsequently, there has been growing interest in cognitive tests of impairment, for which divided attention shows promise as a functional biomarker of acute drug and alcohol intoxication. In this study, we examined whether a newly developed gamified dual-task test of impairment, 'Save the Bunnies' would be sensitive to acute alcohol intoxication. We recruited 36 participants in order to test for differences in task performance in an alcohol vs placebo condition at BrAC levels of 0.05% ascending, 0.08%, and 0.05% descending. Overall, three of the four performance measures on StB were sensitive to alcohol intoxication, including tracking accuracy, reaction time, and hit accuracy, with moderate to large magnitude differences between conditions. In addition, we compared Save the Bunnies! against a commercially available dual-task test of impairment, the Druid, in order to establish convergent validity, compare the sensitivity of each test, and assess user preference. Overall, correlational measures between Save the Bunnies! and Druid were lower than expected. The Druid also appeared to lack sensitivity when classifying individuals on the basis of its impairment guidelines.

description: This report focuses on providing a synthetic description of COVID-19 communication strategies and practices by governments and public health authorities in 15 countries in the EU and beyond. The report contains a description and analysis of national COVID-19 communication by different COVINFORM partners, presenting the work developed for each country. This includes, first, the review and description of communication strategies and practices across time of governments and public health authorities on a national, regional, and local level in selected communities, including strategies to influence behaviour change, and a detailed analysis of factors influencing communication practices. Second, it includes the review of research and professional analysis to national communication on COVID-19 crisis. Third, the main learnings, best practices and successful communications approaches in each country as well as relevant indicators that can be used to evaluate communication efficiency.

The report also identifies at an early stage some main lessons and best practices for effective risk communication in pandemics (beyond the current COVID-19 pandemic), which not only emerge from countries’ communication analysis, but which are also supported by literature.

This report is the first outcome of WP7 Inclusive COVID-19 communication for behaviour change and addressing misinformation and will be updated in M26. This second iteration will focus communication with and for communities, which will be analysed on COVINFORM case studies.

description: Photovoltaic effect, e.g., solar cells, converts light into DC electric current. This phenomenon takes place in various setups such as in noncentrosymmetric crystals and semiconductor pn junctions. Recently, we proposed a theory for producing DC spin current in magnets using electromagnetic waves, i.e., the spin-current counterpart of the solar cells. Our calculation shows that the nonlinear conductivity for the spin current is nonzero in a variety of noncentrosymmetric magnets, implying that the phenomenon is ubiquitous in inversion-asymmetric materials with magnetic excitations. Intuitively, this phenomenon is a bulk photovoltaic effect of magnetic excitations, where electrons and holes, visible light, and inversion-asymmetric semiconductors are replaced with magnons or spinons, THz or GHz waves, and asymmetric magnetic insulators, respectively. We also show that the photon-driven spin current is shift current type, and as a result, the current is stable against impurity scattering. This bulk photovoltaic spin current is in sharp contrast to that of well-known spin pumping that takes place at the interface between a magnet and a metal.

description: We study breaking stress of deformed Coulomb crystals in a neutron star crust, taking into account electron plasma screening of ion-ion interaction; calculated breaking stress is fitted as a function of electron screening parameter. We apply the results for analyzing torsional oscillation modes in the crust of a non-magnetic star. We present exact analytic expression for the fundamental frequencies of such oscillations and show that the frequencies of all torsional oscillations are insensitive to the presence of the outer neutron star crust. The results can be useful in theoretical modeling of processes involving deformed Coulomb crystals in the crust of neutron stars, such as magnetic field evolution, torsional crustal or thermo-elastic quasi-periodic oscillations of flaring soft gamma-ray repeaters, pulsar glitches. The applicability of the results to soft gamma-ray repeaters is discussed.

description: The inability of existing models to solve multidimensional real-time problems, using a single criterion, led to the development of Multi Criteria Decision Making Methodology. In this theses we present the main multicriteria decision making methods. The first chapter is an introductory analysis of decision making theory and analysis. The second chapter lists the methods of multi utility theory, AHP, DEA and TOPSIS methods. The third chapter presents the theories of the predominance relations family, PROMETHEE and ELECTRE. The last chapter presents a program application which implements the ELECTRE methods in a modern multicriteria real-time problem, and helps us understand the philosophy of predominance methods in order to coclude the effectiveness and validity of these methods.
Origin of carbonate hosted gold rich replacement deposits and related mineralization styles in the Ketza River deposit, Yukon Territory
Creators: name: Fonseca, Ana L.
Publisher: name: University of British Columbia
Year: 2009

description: The Ketza River deposit consists of gold-rich, base metal-poor oxidized and unoxidized manto style orebodies and Fe-silicate alteration zones hosted in Early Cambrian limestones, and quartzsulphide veins and stockwork in Late Proterozoic to Eady Cambrian metasedimentary rocks. Sulphide mineralogy in unoxidized mantos, Fe-silicate alteration zones and in veins and stockwork consists mainly of pyrrhotite, pyrite, arsenopyrite, marcasite, and chalcopyrite. Minor amounts of native bismuth are present in all ore types. Gangue minerals are mainly carbonates (calcite and ankerite), and quartz. Additionally, Fe-silicate alteration zones have locally abundant magnetite and Fe-amphibole. The area was affected by two episodes of folding, followed by two of faulting. All units exposed in the area are affected by the deformation. The two phases of folds have coincident, E-W-trending axes, and are distinguished on the basis of their vergence and nature of the axial planar foliation. First phase folds (FO have upright axial-planar foliation (SO, whereas second phase folds (F2) have moderately NE-dipping axial planar foliation (S2) defined by spaced crenulation cleavage. Folding was followed by NNE-directed thrusting, which was in turn followed by doming and extension that produced horsts and grabens. Arsenopyrite geothermometry was performed in ore samples from various locations in the deposit, and yielded 27.4 to 29.4 average atomic % arsenic, corresponding to temperatures below 330°C. ^Ar/^Ar analysis of white mica from a quartz-sulphide vein gives a mid-Cretaceous (108 +/- 0.3 Ma) age for the mineralization that coincides with the emplacement of the Cassiar plutonic suite. Lead isotopic ratios of samples from the different styles of mineralization in the Ketza River deposit plot in overlapping fields, suggesting a genetic relationship between the different ore types. Analyses from carbonate hosted mineralization have a wider spread, suggesting more complex rock-fluid interactions or less homogenization of Pb isotopes. The distribution of orebodies along normal faults and the coincidence of the age of mineralization with the emplacement of a plutonic suite in the region, make the Ketza River deposit a typical intrusion centered sedimentary rock hosted hydrothermal system, with different ore manifestations according to host rock type. However, the central part of the system (the intrusive source of heat, and possibly fluids, metals, and sulphur) is not exposed.

description: Η μεταπτυχιακή εργασία με τίτλο "Ο Βασιλεύς της Ελλάδος Οθων και η διαχείριση της μνήμης του από την ελληνική ιστοριογραφία" σκοπό έχει να περιγράψει και να αναδείξει τη διαχρονική αντιμετώπιση της εικόνας του πρώτου μονάρχη, από τη στιγμή της βίαιης αποπομπής του (Οκτώβριος 1862) μέχρι και σήμερα. Ερευνητικό έναυσμα υπήρξαν οι διαφορετικοί και συχνά αντικρουόμενοι χαρακτηρισμοί, με τους οποίους οι έλληνες ιστορικοί περιέγραψαν το έργο και την προσωπικότητα του Όθωνα. Κύριοι ερευνητικοί άξονες της παρούσης εργασίας ήταν οι εκάστοτε προβαλλόμενοι από την ελληνική ιστοριογραφία παράγοντες, που οδήγησαν τους Ελληνες στη ρήξη με την ανώτατη κρατική τους αρχή. Το πιο ενδιαφέρον κομμάτι της εργασίας στάθηκε η ανεύρεση των ιστορικών τομών που ορίζουν την αλλαγήστην εξελικτική αντιμετώπιση της Βασιλικής εικόνας και η ανάλογη κατάρτιση των διαφορετικών ιστορικο-ιδεολογικών ενοτήτων.
description: The dissertation titled "King of Greece Otho and the handling of his memory from the Greek historiography" intends to describe and show the outline of the image of the first monarch, over the years, since his violent expulsion (October 1862) until today. A reason for research were the different and often contradictory characterizations in which greek historians described the work and personality of Otho. Main points of research in the present project were the factors that greek historiography brought forth, regarding the reasons why Greeks were led to rupture with their superior govermental authority. The most interesting part of the project was the finding of the historic sections which define the change in the confrontation of the royal image and the constitution of different historial and ideological units.

description: The heavy-quark expansion for inclusive semi-leptonic B decays introduces $\barΛ$ and $λ_1$, which are matrix elements in heavy-quark effective field theory. We review how they can be obtained from an analysis of the heavy quark mass dependence of heavy-light meson masses in lattice QCD. We present preliminary results for the bottom quark mass, $m_b$, using $\barΛ$ and $λ_1$ for the $B_s$ meson from a 2+1 sea-flavor unquenched calculation.

description: Η παρούσα εργασία μελετάει την ασυμπίεστη, διδιάστατη, σταθερή και ιξώδη ροή αέρα πάνω από διπλό και τριπλό τροποποιημένο τοξωτό θερμοκήπιο. Το υπολογιστικό πεδίο με τις κατάλληλες οριακές συνθήκες προσομοιώνει τη ροή μέσα σε αεροσήραγγα. Οι εξισώσεις Navier –Stokes και συνέχειας αδιαστατοποιούνται ως προς την ομοιόμορφη ταχύτητα εισόδου της ροής και το ύψος των θερμοκηπίων. Η αριθμητική επίλυση των εξισώσεων Navier – Stokes και συνέχειας γίνεται με την μέθοδο των πεπερασμένων στοιχείων σταθερής μάζας (Galerkin method) με οριακές συνθήκες την ομοιόμορφη ταχύτητα ελεύθερης ροής στην αρχή του πεδίου ροής, τις συνθήκες μη ολισθήσεως στα όρια του πεδίου ροής και τις ελεύθερες οριακές συνθήκες στην έξοδο του πεδίου. Ο αριθμός Reynolds ορίζεται ως προς το ύψος του εμποδίου και την ομοιόμορφη ταχύτητα εισόδου του πεδίου ροής. Οι αριθμοί Reynolds ποικίλουν από 0,02 μέχρι 1370 για το θερμοκήπιο με δυο παραβολικές οροφές και από 0,02 μέχρι 1490 για το θερμοκήπιο με τρεις παραβολικές οροφές. Τα αριθμητικά αποτελέσματα όπως οι γραμμές ροής, τα προφίλ της ταχύτητας σε διάφορα σημεία του υπολογιστικού πεδίου, το μήκος αποκόλλησης και προσκόλλησης, το πάχος της οριακής στοιβάδας, οι γραμμές ίσης πίεσης και διατμητικής τάσης, οι γραμμές ίσου στροβιλισμού, οι συντελεστές πίεσης και διατμητικής τάσης του τοιχώματος και ελεύθερης διατμητικής τάσης καθώς και οι γραμμές ίσης ενέργειας παρουσιάζονται και συγκρίνονται ποιοτικά με διαθέσιμα αριθμητικά και πειραματικά δεδομένα για να ελεγχθεί η ακρίβεια των αριθμητικών προβλέψεων.
description: The present work studies an incompressible two-dimensional, steady, viscous air flow over multispan greenhouses with two and three parabolic roofs. The boundary conditions at the wall, the inlet and the outlet determine airflow in the wind tunnel. The N-S and continuity equations have been solved numerically, using the Galerkin Finite Element Method. The N-S and continuity equations have been solved numerically, using the Galerkin Finite Element Method. The Reynolds numbers are varied from 0.02 to 1370 for the greenhouse of two parabolic roofs and 0.02 to 1490 for the greenhouse of three parabolic roofs. Numerical results, such as streamlines, velocities distribution, separation and reattachment length, boundary layer thickness, isobar, vorticity and shear stress contours, pressure coefficient and wall shear stress coefficient and energy contours are compared qualitatively with available numerical and experimental data to verify the precision of numerical predictions.

description: We present the Apache Point Observatory BG40 broadband and simultaneous Gemini $r$-band and $i$-band high-speed follow-up photometry observations and analysis of the 40.5 minute period eclipsing detached double-degenerate binary SDSS J082239.54$+$304857.19. Our APO data spans over 318 days and includes 13 primary eclipses, from which we precisely measure the system's orbital period and improve the time of mid-eclipse measurement. We fit the light curves for each filter individually and show that this system contains a low-mass DA white dwarf with radius $R_A=0.031\pm0.006~{\rm R_\odot}$ and a $R_B=0.013\pm0.005~{\rm R_\odot}$ companion at an inclination of $i=87.7\pm0.2^\circ$. We use the best-fitting eclipsing light curve model to estimate the temperature of the secondary star as $T_{\rm eff}=5200\pm100~{\rm K}$. Finally, while we do not record significant offsets to the expected time of mid-eclipse caused by the emission of gravitational waves with our 1-year baseline, we show that a $3σ$ significant measurement of the orbital decay due to gravitational waves will be possible in 2023, at which point the eclipse will occur about $8$ seconds earlier than expected.

Alignment of Dust with Magnetic Inclusions: Radiative Torques and Superparamagnetic Barnett and Nuclear Relaxation

description: We consider grains with superparamagnetic inclusions and report two new condensed matter effects that can enhance the internal relaxation of the energy of a wobbling grain, namely, superparamagnetic Barnett relaxation, as well as, an increase of frequencies for which nuclear relaxation becomes important. This findings extends the range of grain sizes for which grains are thermally trapped, i.e. rotate thermally, in spite of the presence of uncompensated pinwheel torques. In addition, we show that the alignment of dust grains by radiative torques gets modified for superparamagnetic grains, with grains obtaining perfect alignment with respect to magnetic fields as soon as the grain gaseous randomization time gets larger than that of paramagnetic relaxation. The same conclusion is valid for the mechanical alignment of helical grains. If observations confirm that the degrees of alignment are higher than radiative torques can produce alone, this may be a proof of the presence of superparamagentic inclusions.

description: We consider the problem of c-axis transport in double-layered cuprates, in particular with reference to Bi$_{2}$Sr$_{2}$CaCu$_{2}$O$_{8+δ}$ compounds. We exploit the effect of the two barriers on the thermal and tunnel transport. The resulting model is able to describe accurately the normal state c-axis resistivity in Bi$_{2}$Sr$_{2}$CaCu$_{2}$O$_{8+δ}$, from the underdoped side up to the strongly overdoped. We extend the model, without introducing additional parameters, in order to allow for the decrease of the barrier when an external voltage bias is applied. The extended model is found to describe properly the c-axis resistivity for small voltage bias above the pseudogap temperature $T^{*}$, the c-axis resistivity for large voltage bias even below $T_c$, and the differential $dI/dV$ curves taken in mesa structures.

description: The Freight Movement and Intermodal Access in Kentucky Study (SPR 98-189) is being conducted by the Kentucky Transportation Center on behalf of the Kentucky Transportation Cabinet. There are two main objectives of the study: 1) evaluation of the access for trucks between intermodal or other truck generating sites and the National Highway System (NHS) and 2) furthering the understanding of freight commodity flows throughout the state. This report summarizes the access evaluation for a facility located in Logan County in the Barren River Development District (ADD) and KYTC Highway District# 3. The location of the site is shown in Figure 1. Work on other specific sites as well as the freight commodity flow task is ongoing and is documented elsewhere.  The sites to be evaluated were selected from two existing databases (a truck facility survey from 1994 and the intermodal facility inventory) based on ADD and KYTC Highway District planner recommendations, geographic location, distance to the national highway system, and the number of trucks accessing the site. Consideration was also made for the freight type handled and transportation modes used. This site is located on US 431 in Logan County. The National Highway System route serving the area is US 68 shown in Figure 1.  A phone survey was conducted with the facility truck routing personnel early in the study process. The site was visited on October 26, 1998 for data collection and December 5, 1998 for video recording. The only facility in the area is Logan Aluminum located on US 431 north of Russellville. The approximate location is also shown in Figure 1. The surrounding area is generally rural and agricultural. The phone survey found approximately 200 trucks per day accessing this site (in and out), while HIS data indicates 720 trucks per day travel along US 431. The site trucks are generally flatbed truck 45-48 feet in length. The phone survey information can be found in Appendix B.  A concern mentioned in the phone survey was the absence of a southern bypass around Russellville. The Six Year Highway Plan includes the design for construction of a southern bypass. Also included in the Six Year Highway Plan is a project to widen a section of US 431 from near Logan Aluminum to north of the Russellville Bypass.
