MATERIAL EXAMINED. — Seven traces; four traces preserved as convex hyporeliefs on slab M486_ 2022.1.1; three traces preserved as convex hyporeliefs on slab M486_ 2022.1.2.
DESCRIPTION
Traces are horizontal, unbranched, straight to curved, run in different directions and up to 3.0 mm wide. The longest course is 72 mm. The traces consist of two thin and up to 1.4 mm wide parallel hypichnial ridges separated by a central groove that is up to 0.8 mm wide (Fig. 3C, D).
REMARKS
The ichnogenus Diplopodichnus Brady, 1947 is reported from the Late Proterozoic to the Early Jurassic (Buatois et al. 1998; Uchman et al. 2011 and references therein). D. biformis is widely recorded in Palaeozoic deposits including many occurrences in Permian formations worldwide (e.g. Brady 1947; Lucas et al. 2004, 2005; Contardi & Santi 2009; Avanzini et al. 2011a; Lima & Netto 2012; Moreau et al. 2020).

description: In this work we propose an alternative model to explain the spontaneous exchange bias (SEB) effect observed in spin glass (SG)-like systems. As in a previously proposed model (Ref. 1), it is based on the unconventional dynamics of the SG-like moments at the magnetic hysteresis cycle. However, using a reliable estimate of the amount of SG-spins that are relaxing during the cycle, the new model can correctly describe the changes in the SEB observed for measurements performed at different temperatures and different maximum applied fields.

description: The generalized Dirac equation of the third order, describing particles with spin 1/2 and three mass states, is analyzed. We obtain the first order generalized Dirac equation in the 24-dimensional matrix form. The mass and spin projection operators are found which extract solutions of the wave equation corresponding to pure spin states of particles. The density of the electromagnetic current is obtained, and minimal and non-minimal (anomalous) electromagnetic interactions of fermions are considered by introducing three phenomenological parameters. The Hamiltonian form of the first order equation has been obtained.

description: Die Koordination arbeitsteiliger Prozesse in der Wertschopfungskette kann marktlich, vertraglich oder durch vertikale Integration vollzogen werden. Im Rahmen des Markt-Hierarchie-Paradigmas der Transaktionskostentheorie ist diese Entscheidung zwischen verschiedenen Formen der contractual governance vielfach diskutiert und empirisch analysiert worden. Der vorliegende Beitrag rückt die Steuerung der Supply Chain durch Vertrauensaufbau und damit Fragen der relational governance in den Vordergrund. In einer empirischen Studie wurden 357 Schweinemaster zu ihrem Vertrauen in die abnehmenden Schlachtunternehmen befragt. Es zeigten sich deutliche Abweichungen hinsichtlich der verschiedenen Abnehmer. Überraschend ist auch, dass sich die Determinanten des Vertrauensaufbaus, die beispielhaft für zwei marktführende Schlachtunternehmen erhoben wurden, wesentlich unterscheiden.

description: A Morita context is constructed for any comodule of a coring and, more generally, for an $L$-$\cC$ bicomodule $Σ$ for a pure coring extension $(\cD:L)$ of $(\cC:A)$. It is related to a 2-object subcategory of the category of $k$-linear functors $\Mm^\Cc\to\Mm^\Dd$. Strictness of the Morita context is shown to imply the Galois property of $Σ$ as a $\cC$-comodule and a Weak Structure Theorem. Sufficient conditions are found also for a Strong Structure Theorem to hold. Cleft property of an $L$-$\cC$ bicomodule $Σ$ -- implying strictness of the associated Morita context -- is introduced. It is shown to be equivalent to being a Galois $\cC$-comodule and isomorphic to $\End^\cC(Σ)\otimes_{L} \cD$, in the category of left modules for the ring $\End^\cC(Σ)$ and right comodules for the coring $\cD$, i.e. satisfying the normal basis property. Algebra extensions, that are cleft extensions by a Hopf algebra, a coalgebra or a pure Hopf algebroid, as well as cleft entwining structures (over commutative or non-commutative base rings) and cleft weak entwining structures, are shown to provide examples of cleft bicomodules. Cleft extensions by arbitrary Hopf algebroids are described in terms of Morita contexts that do not necessarily correspond to coring extensions.

The second part is devoted to cosmological inflation and the generation of primordial fluctuations. In part three it will be shown how these initial perturbation evolve and produce the temperature anisotropies of the cosmic microwave background radiation. Comparing the theoretical prediction for the angular power spectrum with the increasingly accurate observations provides important cosmological information (cosmological parameters, initial conditions).

description: Machine Learning (ML) has already fundamentally changed several businesses. More recently, it has also been profoundly impacting the computational science and engineering domains, like geoscience, climate science, and health science. In these domains, users need to perform comprehensive data analyses combining scientific data and ML models to provide for critical requirements, such as reproducibility, model explainability, and experiment data understanding. However, scientific ML is multidisciplinary, heterogeneous, and affected by the physical constraints of the domain, making such analyses even more challenging. In this work, we leverage workflow provenance techniques to build a holistic view to support the lifecycle of scientific ML. We contribute with (i) characterization of the lifecycle and taxonomy for data analyses; (ii) design principles to build this view, with a W3C PROV compliant data representation and a reference system architecture; and (iii) lessons learned after an evaluation in an Oil & Gas case using an HPC cluster with 393 nodes and 946 GPUs. The experiments show that the principles enable queries that integrate domain semantics with ML models while keeping low overhead (<1%), high scalability, and an order of magnitude of query acceleration under certain workloads against without our representation.

description: This paper discusses traversable wormholes that differ slightly but significantly from those of the Morris-Thorne type under the assumption of cylindrical symmetry. The throat is a piecewise smooth cylindrical surface resulting in a shape function that is not differentiable at some value. It is proposed that the regular derivative be replaced by a one-sided derivative at this value. The resulting wormhole geometry satisfies the weak energy condition.

description: Exploiting final-state interactions and/or identity interference, analysis of anisotropic correlations of particles at low-relative velocities yields information on the anisotropy of emission sources in heavy-ion reactions. We show that the use of cartesian surface-spherical harmonics in such analysis allows for a systematic expansion of the correlations in terms of real angular-moment coefficients dependent on relative momentum. The coefficients are directly related to the analogous coefficients for emission sources. We illustrate the analysis with an example of correlations generated by classical Coulomb interaction.

Diese auf Grundlage der Effizienz- und Verteilungstheorien institutionellen Wandels durchgeführte institutionenöko-nomische Analyse zeichnet sich durch eine besondere Komplexität in Form einer doppelten Mehrebenenperspektive aus: Zum einen werden mit der EU-, Bundes-, Landes- und Land-kreisebene die relevanten föderalen Ebenen betrachtet. Zum anderen wird dies durch einen ebenfalls auf vier Ebenen differenzierten Institutionenbegriff ergänzt. Diese von Ostrom (1998) abgeleiteten vier Regelebenen, die wiederum auf allen föderalen Ebenen lokalisiert sind, beinhalten jeweils eine Vielzahl von Regeln, die sich gegenseitig beeinflussen und des-halb von Ostrom (1998; 1999) als "verschachtelte Regeln" bezeichnet werden. In dem Beitrag wird aufgezeigt, welche institutionellen Anreize und Hemmnisse das Handeln der Akteure entscheidend beeinflussen. Aufgrund der durch die kürzlich veröffentlichte neue Verordnung (EG) Nr. 1698/2005 zur Entwicklung des ländlichen Raumes weiterhin bestehenden politi-schen Relevanz werden abschließend einige Politikempfehlungen abgeleitet.

description: Load optimisation applied to air bending is used to optimise the damage state in the formed component. In [1], elastomer bending is presented, where superposed stresses due to the reaction forces of the elastomer cushion lead to reduced damage growth. Replacing the elastomer cushion with compressive loads allows for optimisation of these loads such that the damage, estimated with the stress triaxiality, is reduced. The optimisation is accomplished with the commercial FEM‐Software Abaqus as the solver for the mechanical problem where Sequential Quadratic Programming (SQP) is used within Matlab to generate improved loads.

description: Cooperatives are not only a legal form, but also a form of organisation, which is owned by a group of individuals. For gaining and sustaining competitiveness cooperatives are forced to grow into certain minimum optimal size categories. Common measures of size are turnover or total assets. But, for cooperatives the number of members has been a quite popular measure for cooperatives' success, size, and their attractiveness. Although often mentioned, the number of members has only been taken as a given value, ignoring the influence of the group itself on its own size. However, there has been no attempt to measure the potential size of a group and its growth dynamic under a given set-up. With the development of a strategic decision game for a hypothetical member, we attempt to show, how the individual member influences the size of his group. Our findings will provide more insight into the overall understanding of cooperatives as a specific organisational and legal form of corporation. Genossenschaften sind nicht nur eine Rechtsform, sondern gleichzeitig eine Form der Organisation, die durch eine Gruppe von Individuen getragen wird. Für die Behauptung im Wettbewerb wird von Genossenschaften eine bestimmte Mindestgröße verlangt. Als Größenkriterien werden neben den üblichen finanzwirtschaftlichen Kennzahlen vor allem die Zahl der Mitglieder als Maß ihres Erfolges und ihrer Attraktivität verwendet. Allerdings gab es noch keinen Versuch, die potenzielle Größe und die Wachstumsdynamik einer Gruppe unter festgelegten Bedingungen zu charakterisieren und zu quantifizieren. Anhand eines strategischen Entscheidungsspiels wird gezeigt, wie das einzelne Mitglied die Größe seiner Gruppe beeinflussen kann. Außerdem zeigen wir, dass Gruppenwachstum einen exponentiellen Charakter aufweist. Diese Erkenntnisse sind für das Gesamtverständnis der Genossenschaft als Organisations- und Rechtsform unerlässlich.

description: Breast cancer (BC) is the most preval ent cause of cancer-related death in women worldwide. BC is frequently associated with elevated levels of nicotinamide phosphoribos yltransferase (NAMPT) in blood and tumor tissue. MicroRNA-494 (miR-494) has been described to play key anti-tumor roles in human cancers. The aim of the present study was to investigate the inhibitory effect of miR-494 on NAMPT-mediated viability of BC cells. In this experimental study, MCF-7 and MDA-MB-231 cells were cultured and then transfec ted with miR-494 mimic, miR-494 inhibitor and their negative controls. The mRNA and protein expression of NAMPT were assessed using real-time PCR and Western blotting, respectively. Subseq uently, intracellular NAD levels were determined by a colorimetric method. Finally, cell apoptosis was examined by fl ow cytometry. Bioinformatics evaluations pre- dicted NAMPT as a miR-494 target gene which was confirmed by luciferase reporter assay. Our results showed an inverse relationship between the expression of miR-494 and NAMPT in both MCF-7 and MDA-MB-231 cell lines. miR-494 significantly down-regulated NAMPT mRNA and protein expression and was also able to reduce the cellular NAD content. Cell viability was decreased fo llowing miR-494 up-regulation. In addition, apoptosis was induced in MCF-7 and MDA-MB-231 cells by miR-494 mimic. Our findings indicate that miR-494 acts as a tumor suppressor and has an important effect in suppressing the growth of BC cells through NAMPT. Therefore, miR-494 might be considered as a novel therapeutic target for the management of human breast cancer.

description: Needs analysis is a set of procedures used to collect information about learners’ needs. In this study, the researchers conducted a community service project by conducting a needs analysis to investigate the learners’ needs in studying English language skills. This survey study involved 60 English students at an Islamic university in Malang City, Indonesia. Having collected and analyzed data from the questionnaire and interview, the researchers found that most respondents in this study were willing to improve their speaking and writing skills. The students also found that some of the materials were not suitable for their needs and were occasionally boring. The researchers, therefore, suggest that the lecturers need to conduct a more thorough needs analysis and upgrade their teaching methods to attract the students to learn English more enthusiastically. The future needs analysis can be conducted at the beginning of the course, so the results can be used as the basis to modify existing academic materials and teaching methods that suit the learners’ needs more accurately.

description: We explore and contrast the capabilities of future colliders to probe the nature of the electro-weak phase transition. We focus on the real singlet scalar field extension of the Standard Model, representing the most minimal, yet most elusive, framework that can enable a strong first-order electro-weak phase transition. By taking into account the theoretical uncertainties and employing the powerful complementarity between gauge and Higgs boson pair channels in the searches for new scalar particles, we find that a 100 TeV proton collider has the potential to confirm or falsify a strong first-order transition. Our results hint towards this occurring relatively early in its lifetime. Furthermore, by extrapolating down to 27 TeV, we find that a lower-energy collider may also probe a large fraction of the parameter space, if not all. Such early discoveries would allow for precise measurements of the new phenomena to be obtained at future colliders and would pave the way to definitively verify whether this is indeed the physical remnant of a scalar field that catalyses a strong first-order transition.

Magnetar giant flares and afterglows as relativistic magnetized explosions
Creators: name: Lyutikov, Maxim
Publisher: name: arXiv
Year: 2005
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: (Abridged) We propose that giant flares on Soft Gamma-Ray Repeaters produce relativistic, strongly magnetized, weakly baryon loaded magnetic clouds, somewhat analogous to solar coronal mass ejection (CME) events. Flares are driven by unwinding of internal non-potential magnetic fields which leads to slow build-up of magnetic energy outside of the neutron star. For large magnetospheric currents, corresponding to a large twist of external magnetic field, magnetosphere becomes dynamically unstable on \Alfven crossing times scale of inner magnetosphere, $t_A \sim R_{NS}/c \sim 30 μ$sec. Released magnetic energy results in formation of a strongly magnetized, pair-loaded, quasi-spherically expanding flux rope, topologically connected by magnetic field to the neutron star during the prompt flare emission. Magnetic stresses of the tied flux rope lead to late collimation of the expansion, on time scales longer than giant flare duration. Relativistic bulk motion of the expanding magnetic cloud, directed at an angle $θ\sim 135^\circ$ to the line of sight (away from the observer), results in a strongly non-spherical forward shock with observed non-relativistic apparent expansion and bulk motion velocities $β_{app} \sim \cot θ/2 \sim 0.4 $ at times of first radio observations approximately one week after the burst. Interaction with a shell of wind-shocked ISM and then with the unshocked ISM leads to deceleration to non-relativistic velocities approximately one month after the flare.

description: The presence of some microorganisms in the respiratory tract is a known risk factor for the infection of air passages; however, it is not clear whether this holds true for Candida spp. Thus, our objective was to determine the frequency of yeast colonization in the tracheobronchial secretions of critically ill intubated patients and to assess the presence of these yeasts in the infra-cuff region of the endotracheal tube (ET). Patients aged 18 years or older who had been using an endotracheal tube for 48 hours were recruited. Tracheal secretions were collected; after extubation, the ETs were cut into two fragments in the infra-cuff region. One of these fragments was placed in a solution containing antibiotics and sent to the lab for cultu re and identification of yeasts. The remaining fragment was fixed and subjected to scanning electron microscopy (SEM). In total, 20 patients with an average age of 73.3 years (± 13.1) participated in this study. These patients remained under endotracheal intubation and invasive mechanical ventilation for an average of 6. 4 (± 1.8) and 13.5 days (± 15), respectively. Of these patients, 45 % showed respiratory tract colonization by yeasts of the Candida genus, with C. albicans being the most frequently isolated species (66.7 %). Moreover, in almost 90 % of these patients, blastoconidia of the same yeast were found in the infra-cuff portion of the ET, as evidenced by SEM, strongly fixed on the ET surface. Yeasts isolated from both the infra-cuff region and the tracheobronchial secretions were susceptible to amphotericin B and fluconazole. In conclusion, our results show that the frequency of colonization by yeasts of the Candida genus in the tracheobronchial secretions of intubated patients within 48 hours is high, and that these species can also be found as a biofilm on the ET surface.

description: Emerging evidence suggests the potential use of rapamycin in treatment of several neurological disorders. The drug readily crosses the blood brain barrier and may exert direct immunomodulatory effects within the brain. Microglia are the main innate immune cells of the brain, thus critically involved in the initiation and development of inflammatory processes at this level. However, there are conflicting data from rodent studies about the pharmacological effects of rapamycin on microglial inflammatory responses. Considering that rodent microglia display relevant biochemical and harmacological differences compared to human microglia, in the present study we studied the effects of rapamycin in an experimental model of human microglia, the human microglial clone 3 (HMC3) cell line. Rapamycin was tested in the nM range both under basal conditions and in cells activated with a pro-nflammatory cytokine cocktail, consisting in a mixture of interferon-γ and interleukin-1β (II). The drug significantly increased II stimulatory effect on interleukin-6 (IL-6) expression and release in the HMC3 cells, while reducing the production of free oxygen radicals (ROS) both under basal conditions and in cells activated with II. Consistently with its known molecular mechanism of action, rapamycin reduced the extent of activation of the so-called ‘mechanistic’ target of rapamycin complex 1 (mTORC1) kinase and the total amount of intracellular proteins. In contrast to rodent cells, rapamycin did not alter human microglial cell viability nor inhibited cell proliferation. Moreover, rapamycin did not exert any significant effect on the morphology of the HMC3 cells. All together these data suggest that the inhibition of mTORC1 in human microglia by rapamycin results in complex immunomodulatory effects, including a significant increase in the expression and release of the pro-inflammatory IL-6.

description: Η επιτακτική ανάγκη για κατανεμημένα δίκτυα κινητής τηλεφωνίας (εσωτερική κάλυψη) προέρχεται άμεσα από τις μεγάλες ανάγκες που έχουν οι χρήστες που βρίσκονται σε εσωτερικούς χώρους. Πολλές φορές το εξωτερικό δίκτυο κινητής τηλεφωνίας (macro network) δεν μπορεί να καλύψει επαρκώς τις μεγάλες ανάγκες των χρηστών. Οι περισσότεροι χρήστες περνάμε αρκετό χρόνο σε κλειστούς χώρους, όπως το γραφείο, σταθμούς τρένων, στάδια κ.α. Συνήθως οι 2 από τις 3 φωνητικές κλήσεις προέρχονται από χρήστες που βρίσκονται σε εσωτερικούς χώρους, ενώ για τις υπηρεσίες δεδομένων το ποσοστό αυτό υπερβαίνει ακόμα και το 90%. Για πολλά χρόνια οι χρήστες που βρίσκονταν σε εσωτερικούς χώρους είχαν κάλυψη μόνο από τα εξωτερικά δίκτυα κινητής τηλεφωνίας. Αυτό απαιτούσε μεγάλη ισχύ εκπομπής από τους σταθμούς βάσης και χρησιμοποιούσαν ένα μεγάλο μέρος του διαθέσιμου για κάθε πάροχο φάσματος. Έτσι κατέστη αναγκαία η χρήση δικτύων εσωτερικής κάλυψης που θα προσέφεραν υψηλής ποιότητας υπηρεσίες. Η παρούσα διπλωματική έχει ως θέμα την ανάλυση και παρουσίαση των απαιτήσεων αλλά και της διαδικασίας του σχεδιασμού των κατανεμημένων δικτύων κινητής τηλεφωνίας (DAS). Στα πρώτα κεφάλαια (πρώτο, δεύτερο και τρίτο) ήταν αναγκαία είναι και η αναφορά των βασικών εννοιών των τηλεπικοινω- νιακών δικτύων, εστιασμένα όμως στην χρήση τους ως DAS. Στο τέταρτο κεφάλαιο γίνεται η αναφορά των βασικών στοιχείων και εξαρτημάτων που απαρτίζουν ένα DAS. Στο πέμπτο κεφάλαιο δρομολογείται η διαδικασία που πρέπει να ακολουθηθεί από το σχεδιαστή αλλά και από όλους τους εμπλεκόμενους για την σχεδίαση ενός DAS συστήματος. Δίνεται ιδιαίτερη βάση στον ρόλο του σχεδιαστή. Στο έκτο κεφάλαιο αναλύονται όλα τα εργαλεία που πρέπει να έχει στα χέρια ο σχεδιαστής για την σωστή επίτευξη της σχεδίασης του DAS. Τέλος, στο έβδομο κεφάλαιο σχεδιάζεται ένα κατανεμημένο σύστημα κεραιών με την χρήση του λογισμικού ειδικού σχεδιαστικού λογισμικού.

(Fig. 4)
MATERIAL EXAMINED. — Eight tracks preserved as concave epireliefs on slab M486_ 2022.1.5.
DESCRIPTION
The trackway is 13 cm long, 6 cm wide and composed of four consecutive pes/manus sets (Fig. 4A, B). Pes and manus stride is 6.4-6.5 cm long. The manus tracks are more internal than pes tracks. Both are small sized and semi-plantigrade. Pes imprints are pentadactyl and wider than long (PL = 1.1 cm, PW = 1.8-2.0 cm; Fig. 4). The PL/PW ratio is equal to 0.6. Digit imprints are short, straight to slightly curved and end in an enlarged rounded tip (Fig. 4 C-E). Pes tracks show a short, large and poorly impressed sole with concave proximal margin. The manus tracks are strongly oriented inward, forming an angle of up to 120° with the trackway axis. Manus imprints are pentadactyl and wider than long (ML = 0.9-1.1 cm; MW = 1.6-1.9 cm; ML/MW = 0.6). Imprints of digits are short and end in a small enlarged rounded tip. The manual digits II-III bent inwards. The divarication angle of digits I-V is up 153°.
REMARKS
As noted by Gand et al. (2000) Amphisauropus Haubold, 1970 shares similarities with Merifontichnus Gand, Garric, Demathieu & Ellenberger, 2000. Tracks from Le Bousquet differ from this latter by smaller size and the pedal digit I not parallel to the proximal margin of the sole. Although tracks from Le Bousquet share some similarities with Dolomitipes Marchetti, Voigt & Klein, 2017, this ichnogenus differs in showing manus tracks placed in line or slightly external to the pes, and pedal tracks longer than wide or about as wide as long and 40 to 250 mm long (Marchetti et al. 2019). Amphisauropus represents a widespread Permian ichnogenus that has been reported from many areas including Africa (Voigt et al. 2011; Hminna et al. 2012; Moreau et al. 2020); Argentina (Melchor & Sarjeant 2004); Canada (Mossman & Place 1989; van Allen et al. 2005); Europe (e.g. Gand & Haubold 1984; Gand 1987; Haubold 1971; Santi & Krieger 2001; Ptaszyński & Niedźwiedzki 2004; Voigt 2005; Avanzini et al. 2008; Voigt et al. 2012; Marchetti et al. 2015) and the United States (Lucas et al. 2001). In France, Amphisauropus was previously reported from the Lodève Basin (Gand & Durand 2006) and the Rodez Basin (Gand 1987). Although Gand (1987) reported Amphisauropus in several localities near Banassac-Canilhac this ichnogenus is here for the first time reported from Le Bousquet.

description: Hyperspectral image (HSI) denoising aims to restore clean HSI from the noise-contaminated one. Noise contamination can often be caused during data acquisition and conversion. In this paper, we propose a novel spatial-spectral total variation (SSTV) regularized nonconvex local low-rank (LR) tensor approximation method to remove mixed noise in HSIs. From one aspect, the clean HSI data have its underlying local LR tensor property, even though the real HSI data may not be globally low-rank due to out-liers and non-Gaussian noise. According to this fact, we propose a novel tensor $L_γ$-norm to formulate the local LR prior. From another aspect, HSIs are assumed to be piecewisely smooth in the global spatial and spectral domains. Instead of traditional bandwise total variation, we use the SSTV regularization to simultaneously consider global spatial structure and spectral correlation of neighboring bands. Results on simulated and real HSI datasets indicate that the use of local LR tensor penalty and global SSTV can boost the preserving of local details and overall structural information in HSIs.

CNO and pep neutrino spectroscopy in Borexino: Measurement of the deep underground production of cosmogenic 11C in organic liquid scintillator
Creators: name: Borexino Collaboration
Publisher: name: arXiv
Year: 2006
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: Borexino is an experiment for low energy neutrino spectroscopy at the Gran Sasso underground laboratories. It is designed to measure the mono-energetic $^7$Be solar neutrino flux in real time, via neutrino-electron elastic scattering in ultra-pure organic liquid scintillator. Borexino has the potential to also detect neutrinos from the \emph{pep} fusion process and the CNO cycle. For this measurement to be possible, radioactive contamination in the detector must be kept extremely low. Once sufficiently clean conditions are met, the main background source is $^{11}$C, produced in reactions induced by the residual cosmic muon flux on $^{12}$C. In the process, a free neutron is almost always produced. $^{11}$C can be tagged on an event by event basis by looking at the three-fold coincidence with the parent muon track and the subsequent neutron capture on protons. This coincidence method has been implemented on the Borexino Counting Test Facility data. We report on the first event by event identification of \emph{in situ} muon induced $^{11}$C in a large underground scintillator detector. We measure a $^{11}$C production rate of 0.130 $\pm$ 0.026 (stat) $\pm$ 0.014 (syst) day$^{-1}$ ton$^{-1}$, in agreement with predictions from both experimental studies performed with a muon beam on a scintillator target and \emph{ab initio} estimations based on the $^{11}$C producing nuclear reactions.

description: We study the structure of the formal groups associated to the Morava $K$-theories of integral Eilenberg-Mac Lane spaces. The main result is that every formal group in the collection $\{K(n)^*K({\mathbb Z}, q), q=2,3,...\}$ for a fixed $n$ enters in it together with its Serre dual, an analogue of a principal polarization on an abelian variety. We also identify the isogeny class of each of these formal groups over an algebraically closed field. These results are obtained with the help of the Dieudonné correspondence between bicommutative Hopf algebras and Dieudonné modules. We extend P. Goerss's results on the bilinear products of such Hopf algebras and corresponding Dieudonné modules.

title: DESIGN AND ANALYSIS OF A PAVEMENT MARKER DETECTION SYSTEM

Publisher: name: University of Kentucky Libraries

Subjects: subject: FOS: Civil engineering

description: Personal injuries and property damage due to the failure of snow-plowable pavement markers which detach from pavement surfaces has led to the development of new all-plastic pavement markers which are located entirely below the planar surface of the pavement. The new all-plastic design pushes existing solutions used to avoid striping over highway reflectors into obsolescence since current solutions operate using electromagnets to sense the metal housings of snow-plowable pavement markers. A replacement solution is currently sought by the highway maintenance industry and three different marker detection methods were developed and tested on real-world highways with both new and aging pavement markers to find that optimal solution. With the developed technologies accruing 106,038 observed data points, it is clear that the ideal solution to marker detection and avoidance is the deployment of a machine vision system operating on a deep learning trained model optimized for the detection of differing types of pavement markers on various pavement surfaces. The machine vision system can be further improved in several areas, the most important of which is the optimization model’s processing speeds such that the system could operate at highway speeds while providing real-time analysis of the integrity of installed pavement markers.
