description: The objective of this study was to report the results of the continued monitoring of the performance of guardrail end treatments in traffic accidents. This report includes an analysis of accidents involving the breakaway-cable-terminal (BCT), Kentucky's version of the median BCT (MBCT), Kentucky's weakened turned down (Type 7), the Crash Cushion Attenuating Terminal (CAT), and the Breakmaster System. The report includes data for 349 accidents. This includes 232 accidents involving a BCT, 66 accidents involving a MBCT, 37 accidents involving the Type 7 turned-down end treatment, 12 accidents involving the CAT, and 2 accidents involving the Breakmaster.  Considering all accidents, the BCT performed properly in 76 percent of the accidents. A more detailed analysis showed the importance of installing the BCT using the parabolic flare. Use of the BCT end treatment should be continued where geometries permit. While the MBCT performed properly in 64 percent of all accidents, proper performance was 39 percent when only severe impacts were considered. Use of the MBCT should be eliminated or the MBCT modified due to the problems associated with impacts at shallow angles.  Performance of the Type 7 weakened turned-down end treatment was judged to be proper in 84 percent of the accidents involving this type. Performance appears to justify expanded use. The rollover problem experienced with the original "stiff" turned-down design has been significantly reduced.  Performance was judged to proper in 9 of the 12 accidents involving the CAT. Considering the results of CAT impacts in Kentucky, along with those in other states, permits the conclusion to be drawn that the CAT could be classified as operational. The Breakmaster system may provide an alternative to the CAT; however, additional accident data area needed to evaluate the performance of this system.

description: We report the effect of 4f electron doping on structural, electrical and magneto-transport properties of Dy doped half Heusler Y1-x(Dy)xPdBi (x =0, 0.2, 0.5, 1) thin films grown by pulsed laser deposition. The Dy doping leads to lattice contraction which increases from 0% for the parent x =0 sample to approx 1.3% for x=1 sample with increase in Dy doping. The electrical transport measurements show a typical semi-metallic behaviour in the temperature range 3K to 300K and a sharp drop in resistivity at low temperatures (less than 3K) for all the samples. Magnetotransport measurements and Shubnikov de-Hass oscillations at high magnetic fields demonstrate that for these topologically non-trivial samples, Dy doping induced lattice contraction plays an active role in modifying the Fermi surface, carrier concentration and the effective electron mass. There is an uniform suppression of the onset of superconductivity with increased Dy doping which is possibly related to the increasing local exchange field arising from the 4f electrons in Dy. Our results indicate that we can tune various band structure parameters of YPdBi by f electron doping and strained thin films of Y1-x(Dy)xPdBi show surface dominated relativistic carrier transport at low temperatures.

description: We investigate the exotic Peierls state in the one-dimensional organic compound (EDO-TTF)_{2}X, wherein the Peierls transition is accompanied by the bending of molecules and also by a fourfold periodic array of charge disproportionation along the one-dimensional chain. Such a Peierls state, wherein the interplay between the electron correlation and the electron-phonon interaction takes an important role, is examined based on an extended Peierls-Holstein-Hubbard model that includes the alternation of the elastic energies for both the lattice distortion and the molecular deformation. The model reproduces the experimentally observed pattern of the charge disproportionation and there exists a metastable state wherein the energy takes a local minimum with respect to the lattice distortion and/or molecular deformation. Furthermore, we investigate the excited states for both the Peierls ground state and the metastable state by considering the soliton formation of electrons. It is shown that the soliton excitation from the metastable state costs energy that is much smaller than that of the Peierls state, where the former is followed only by the charge degree of freedom and the latter is followed by that of spin and charge. Based on these results, we discuss the exotic photoinduced phase found in (EDO-TTF)_{2}PF_{6}.

Εάν το δικαίωμα προς ικανοποίηση του οποίου διενεργήθηκε η εκτέλεση ήταν ανύπαρκτο και επιπλέον, ο επισπεύδων-δανειστής βαρύνεται με υπαιτιότητα ως προς την ανυπαρξία του δικαιώματός του, τότε αντίστοιχα και η εκτέλεση είναι άδικη και ο επισπεύδων ευθύνεται για την κάλυψη των ζημιών που επήλθαν εξ αφορμής της αναγκαστικής εκτέλεσης (940 §§1 και 2). Η δυνατότητα αυτή του καθ’ ού αποκλείεται εφόσον η απόφαση κατέστη απρόσβλητη με ένδικα μέσα. Το άδικο στις §§1 και 2 εντοπίζεται στην κίνηση της εκτελεστικής διαδικασίας από τον επισπεύδοντα, μολονότι γνώριζε ότι το δικαιώμά του είναι ανύπαρκτο.Αν η εκτέλεση επισπεύσθηκε δυνάμει άλλου πλην της δικαστικής απόφασης εκτελεστού τίτλου, τίθεται το ζήτημα της αναλογικής εφαρμογής των §§1 και 2 του άρθρου 940, καθώς το άρθρο 940 αναφέρεται μόνο στην περίπτωση της εξαφάνισης της απόφασης μετά από άσκηση ενδίκου μέσου. Θεωρία και νομολογία διχάζονται κατά την εξέταση του θέματος αυτού και έχει διατυπωθεί η γνώμη ότι σκόπιμη θα ήταν η νομοθετική παρέμβαση.Ο καθ’ ού η εκτέλεση οφειλέτης δικαιούται αποζημίωσης και στην περίπτωση αμετάκλητης ακύρωσης της αναγκαστικής εκτέλεσης (§3 940). Το παράνομο στην περίπτωση αυτή συνίσταται στην αμετάκλητη ακύρωση της αναγκαστικής εκτέλεσης. Σε κάθε περίπτωση, επικουρικά έχει την αξίωση του αδικαιολόγητου πλουτισμού (904 ΑΚ).

description: Recently, the diagnosability of {\it stochastic discrete event systems} (SDESs) was investigated in the literature, and, the failure diagnosis considered was {\it centralized}. In this paper, we propose an approach to {\it decentralized} failure diagnosis of SDESs, where the stochastic system uses multiple local diagnosers to detect failures and each local diagnoser possesses its own information. In a way, the centralized failure diagnosis of SDESs can be viewed as a special case of the decentralized failure diagnosis presented in this paper with only one projection. The main contributions are as follows: (1) We formalize the notion of codiagnosability for stochastic automata, which means that a failure can be detected by at least one local stochastic diagnoser within a finite delay. (2) We construct a codiagnoser from a given stochastic automaton with multiple projections, and the codiagnoser associated with the local diagnosers is used to test codiagnosability condition of SDESs. (3) We deal with a number of basic properties of the codiagnoser. In particular, a necessary and sufficient condition for the codiagnosability of SDESs is presented. (4) We give a computing method in detail to check whether codiagnosability is violated. And (5) some examples are described to illustrate the applications of the codiagnosability and its computing method.

description: The assessment of human internal/core temperature (Tcore) is relevant in many scientific disciplines, but also for public health authorities when attempting to identify individuals with fever. Direct assessment of Tcore is often invasive, impractical on a large scale, and typically requires close contact between the observer and the target subject. Non-contact infrared thermometry (NCIT) represents a practical solution in which Tcore can potentially be assessed from a safe distance and in mass screening scenarios, by measuring skin temperature at specific anatomical locations. However, the COVID-19 pandemic has clearly demonstrated that these devices are not being used correctly, despite expert guided specifications available in International Standard Organization (ISO) documents. In this review, we provide an overview of the most pertinent factors that should be considered by users of NCIT. This includes the most pertinent methodological and physiological factors, as well as an overview on the ability of NCIT to track human Tcore. For practical use, we provide a checklist based on relevant ISO standards which are simple to follow and should be consulted prior to using NCIT for assessment of human Tcore. Our intention is for users of NCIT to adopt this checklist, which may improve the performance of NCIT for its ability to track Tcore.
Evaluation of Headwalls and Outlets for Geocomposite Edge Drains on I-75 and I-71

description: Longitudinal, round, perforated pipe edge drains have been used along Kentucky roadways for approximately two decades. Panel (fin) edge drains were first used in Kentucky in 1984. Most of these edge drains were installed on the Interstate and Parkway systems.  Several problems related to the drains have been noted in the last seven years. A number of these problems have been observed to be related to flexible outlet pipes and headwalls.  A recent study was initiated to evaluate headwalls and outlets on I-75 from Lexington, Kentucky to Cincinnati, Ohio (approximately 70 miles) and on I-71 from Louisville, Kentucky to I-75 in Northern Kentucky (approximately 68 miles). This study was initiated as a first phase of a much more intensive study which will evaluate all edge drains and outlets on Interstates and Parkways in Kentucky.  This report documents findings of the investigation of 234 edge drain outlets. Of the 234 outlets investigated, approximately 43 percent of the edge drain outlets inspected were out of service. Approximately 50 percent of the outlet pipes had been damaged during installation. More significant problems were found at the headwall and outlet pipe connection than any other location in the drainage system.  It appears that a maintenance program should be established to clean the troughs of the headwalls and to check the screens for clogging and rust. The metal screens should be replaced with galvanized screens.  Positive flow should also be maintained from the headwalls. The buildup of grass and silt can eventually detour some of the flow. Headwalls located in cuts are more prone to become covered or ponded.  Edge drains and outlets should be inspected after they are installed.  Rigid outlet pipe should be precast into the headwalls. This should help eliminate problems occurring at the headwall connection. Currently, a rigid outlet pipe is connected to an approximately 2-foot long "pigtail" (4-inch flexible pipe) which is precast into the headwall.

description: We investigate the role of squeezing interaction in inducing topological Bogoliubov excitations of a bosonic system. We introduce a squeezing transformation which is capable of reducing the corresponding Bogoliubov-de Gennes Hamiltonian to an effective non-interacting one with the spectra and topology unchanged. In the weak interaction limit, we apply the perturbation theory to investigate the squeezing-induced topological gap opening on bosonic Bogoliubov excitations and find that the squeezing interaction plays an equivalent role as a spin-orbit or Zeeman-like coupling in the effective Hamiltonian. We thus apply this formalism to two existed models for providing deeper understandings of their topological structures. We also construct minimal models based on the elegant Clifford algebra for realizing bosonic topological Bogoliubov excitations. Our construction is potentially applicable for experiments in bosonic systems.

description: A complete and explicit classification of generalized, or local, symmetries of massless free fields of spin $s \geq 1/2$ is carried out. Up to equivalence, these are found to consists of the conformal symmetries and their duals, new chiral symmetries of order $2s$, and their higher-order extensions obtained by Lie differentiation with respect to conformal Killing vectors. In particular, the results yield a complete classification of generalized symmetries of the Dirac-Weyl neutrino equation, Maxwell's equations, and the linearized gravity equations.

Within our formulation, we show generically that every parasupersymmetric quantum system of order p consists of N-fold supersymmetric pairs with N

description: We report on two simultaneous XMM-Newton and INTEGRAL observations of the microquasar GRO J1655-40 during the 2005 outburst when the source was in its high-soft state. The 0.3-200 keV spectra are complex with an overall continuum which may be modeled using an absorbed blackbody together with a weak, steep, power-law component. In addition, there is evidence for the presence of both a relativistically broadened Fe K line and a highly photo-ionized absorber. The photo-ionized absorber is responsible for strong K absorption lines of Fe XXV and Fe XXVI in the EPIC pn spectra and blue-shifted (v = -540 +/- 120 km/s) Ne X and Fe XXIV features in the RGS spectra. The parameters of the photo-ionized absorber were different during the two observations with the ionization parameter, logxi, decreasing from 3.60 +/- 0.04 to 3.30 +/- 0.04 erg cm/s and the column density decreasing from (5.2 +/- 1.0) x 10^22 atom cm-2 to (1.5 +/- 1.0) x 10^22 atom cm-2 during the first and second observations as the 0.5-200 keV GRO J1655-40 luminosity decreased by around a half. At 90% confidence the INTEGRAL data show no evidence of a break in the power-law component up to energies of 380 keV and 90 keV for the first and second observations, respectively.

Construction Evaluation of Hydraway Edge Drains and Outlet Pipes on Interstate 64

description: This report documents the installation of the Hydraway edge drain (version two) on 1-64 in Franklin·Woodford-Scott and Fayette Counties. The edge drain was placed on the back side of the trench against the shoulder and backfilled with a sand/slurry.  From observations on this project and several previous projects, the sand/slurry backfill helps to insure the integrity of the drainage system during initial backfilling. It is apparent that the sand slurry backfill provides a better installation in comparison to previous methods using excavated trench material. Notable trench settlement did occur on this project. It is apparent that insufficient water was used to properly densify the sand. From observations on other projects, it appears that approximately one gallon per linear foot is required to achieve proper density. It appears that the method of flushing the sand, the speed of the construction, and the amount of water needed to achieve proper density will vary on the contractors equipment and methods. The net result is to achieve proper density with out damaging the edge drain. It also appears that the initial asphalt plug is not being properly compacted.  The Hydraway panel was reversed to minimize fabric intrusion into the core of the drain. Fabric intrusion into the inner core of the Hydraway drain appeared to be eliminated when the panel was reversed. When the panel was reversed and trench settlement occurred, the rigid back of the panel was forced to bend in the opposite direction it was designed. The net result was cracking occurring in the rigid backing.  Information reported in Research Report KTC-91-10 "Evaluation of Headwalls and Outlets for Geocomposite Edge Drains on 1-75 and l-71" indicates that 48 percent of the flexible outlet pipes that were inspected were less than 60 percent open. Approximately 10 percent of the rigid outlets inspected during this study were less than 60 percent open, thus showing a substantial increase in performance. A large amount of distress noted on 1-64 was observed in the flexible 4-inch pigtail. If rigid pipe is used throughout the outlet pipe system, performance should increase.
Resonant effects in a voltage-activated channel gating

description: The non-selective voltage activated cation channel from the human red cells, which is activated at depolarizing potentials, has been shown to exhibit counter-clockwise gating hysteresis. We have analyzed the phenomenon with the simplest possible phenomenological models by assuming $2\times 2$ discrete states, i.e. two normal open/closed states with two different states of ``gate tension.'' Rates of transitions between the two branches of the hysteresis curve have been modeled with single-barrier kinetics by introducing a real-valued ``reaction coordinate'' parameterizing the protein's conformational change. When described in terms of the effective potential with cyclic variations of the control parameter (an activating voltage), this model exhibits typical ``resonant effects'': synchronization, resonant activation and stochastic resonance. Occurrence of the phenomena is investigated by running the stochastic dynamics of the model and analyzing statistical properties of gating trajectories.

Critical fluctuations and random-anisotropy glass transition in nematic elastomers

description: We carry out a detailed deuterium NMR study of local nematic ordering in polydomain nematic elastomers. This system has a close analogy to the random-anisotropy spin glass. We find that, in spite of the quadrupolar nematic symmetry in 3-dimensions requiring a first-order transition, the order parameter in the quenched ``nematic glass'' emerges via a continuous phase transition. In addition, by a careful analysis of the NMR line shape, we deduce that the local director fluctuations grow in a critical manner around the transition point. This could be the experimental evidence for the Aizenman-Wehr theorem about the quenched impurities changing the order of discontinuous transition.

Abstract Secukinumab (Cosentyx®) is a fully human monoclonal antibody that selectively targets interleukin (IL)-17A, a proinflammatory cytokine involved in the pathogenesis of psoriatic arthritis (PsA). Administered subcutaneously, the first-in-class anti-IL-17 agent is approved in numerous countries worldwide for the treatment of adults with active PsA. In the phase III FUTURE trials, secukinumab 150 or 300 mg improved the clinical signs and symptoms of PsA versus placebo in patients with active disease despite previous treatment with NSAIDs, biological disease-modifying anti-rheumatic drugs (bDMARDs) and/or tumour necrosis factor inhibitors (TNFi). The benefits of secukinumab were seen regardless of whether or not patients had received previous TNFi therapy, and were maintained during longer term (up to 5 years) treatment. In FUTURE 1 and 5, secukinumab inhibited structural joint damage and was associated with sustained low rates of radiographic progression through 1–3 years of treatment. Treatment with secukinumab improved physical function and health-related quality of life (HR-QOL) and was generally well tolerated, both in the short- and longer-term. In the head-to-head EXCEED trial, secukinumab did not quite attain statistical significance for superiority versus adalimumab in the joint domain. In conclusion, secukinumab is effective across all key PsA domains and is generally well tolerated, and thus represents a useful treatment alternative to TNFi and other bDMARDs in adult patients with active PsA.

Strong and weak coupling limits in optics of quantum well excitons

description: A transition between the strong (coherent) and weak (incoherent) coupling limits of resonant interaction between quantum well (QW) excitons and bulk photons is analyzed and quantified as a function of the incoherent damping rate caused by exciton-phonon and exciton-exciton scattering. For confined QW polaritons, a second, anomalous, damping-induced dispersion branch arises and develops with increasing damping. In this case, the strong-weak coupling transition is attributed to a critical damping rate, when the intersection of the normal and damping-induced dispersion branches occurs. For the radiative states of QW excitons, i.e., for radiative QW polaritons, the transition is described as a qualitative change of the photoluminescence spectrum at grazing angles along the QW structure. Furthermore, we show that the radiative corrections to the QW exciton states with in-plane wavevector approaching the photon cone are universally scaled by an energy parameter rather than diverge. The strong-weak coupling transition rates are also proportional to the same energy parameter. The numerical evaluations are given for a GaAs single quantum well with realistic parameters.

description: In this paper, we investigate the self-affirmation effect on formation of public opinion in a directed small-world social network. The system presents a non-equilibrium phase transition from a consensus state to a disordered state with coexistence of opinions. The dynamical behaviors are very sensitive to the density of long-range interactions and the strength of self-affirmation. When the long-range interactions are sparse and individual generally does not insist on his/her opinion, the system will display a continuous phase transition, in the opposite case with high self-affirmation strength and dense long-range interactions, the system does not display a phase transition. Between those two extreme cases, the system undergoes a discontinuous phase transition.

description: Half-metallic Heusler alloys are amongst the most promising materials for future magnetoelectronic applications. We review some recent results on the electronic properties of these compounds. The origin of the gap in these half-metallic alloys and its connection to the magnetic properties are well understood. Changing the lattice parameter shifts slightly the Fermi level. Spin-orbit coupling induces states within the gap but the alloys keep a very high degree of spin-polarization at the Fermi level. Small degrees of doping and disorder as well as defects with low formation energy have little effect on the properties of the gap, while temperature effects can lead to a quick loss of half-metallicity. Finally we discuss two special issues; the case of quaternary Heusler alloys and the half-metallic ferrimagnets.

description: A new quantum model with rational functions for the potential and effective mass is proposed in a stretchable region outside which both are constant. Starting from a generalized effective mass kinetic energy operator the matching and boundary conditions for the envelope wave functions are derived. It is shown that in a mapping to an auxiliary constant-mass Schrodinger picture one obtains one-period ``associated Lame'' well bounded by two delta-wells or delta-barriers depending on the values of one ordering parameter. The results for bound states of this new solvable model are provided for a wide variation of the parameters.
