Pseudaganides subbiangulatus subsp. dimidiatuo Marchand & Tintant, 1971: 150, pl. II, fig. 1a-c, fig. III, pl. 6.
Nautilus subbiangulatus – Couffon 1919: pl. XVII, figs 7a-7b.
Pseudaganides dimidiatus – Tintant 1994: 36.
DIAGNOSIS. — Small sized nautilus, less than 80 mm, with a compressed and high section. Flat sides becoming slightly rounded on the body-chamber with a flat, sometime concave, venter.
MATERIAL EXAMINED. — France • 1 specimen (complete); NouvelleAquitaine, Saint-Laon, la Grève quarry (POC0051); [46°57’19”N, 0°01’38”W]; Gracilis Zone, Patina Subzone to Anceps Zone; Lower to Middle Callovian; Patrick Branger leg.; MBAN; 2023.PB.N126 (Fig. 14B1-B3).
MEASUREMENTS. — See Table 9.
DISTRIBUTION. — P. dimidiatus is known from Lower Callovian, Gracilis Zone, Patina Subzone, to Middle Callovian, Anceps Zone.
DESCRIPTION
According to Marchand &Tintant (1971), these are small sized individuals, less than 80 mm in diameter, with a compressed and high section. Flanks are flat, becoming slightly rounded on the body-chamber. Suture line with a wide lateral saddle, not as deep as the external one.
REMARKS
As pointed byMarchand & Tintant (1971), P.dimidiatus differs from P. subbiangulatus in several ways. Besides its smaller size, the existence of quite sharp ridges at an earlier stage proves that it is a different species. All the other characteristics of the shell are the same. According to these authors, the age of the two species were different. New in-situ collecting demonstrates that this point of view is probably erroneous. Those authors also assumed that, in the collections, P. dimidiatus was rather common beside the total lack of any other sample of P. subbiangulatus. This study does not confirm this opinion since, at the same level, we collected more P. subbiangulatus than P. dimidiatus. Therefore, another explanation which could be considered would be a possible sexual dimorphism. This phenomenon has been described by several authors in modern Nautilus. Willey (1902) was the first biologist who noticed that males are larger and have a broader aperture than females. More recent studies (Saunders & Spinosa 1978; Saunders et al. 2017) lead to the same conclusions. Consequently, we suggest that P. dimidiatus, the smallest shell, could be the presumed female and P. subbiangulatus, the largest, could be the male of a single species.

description: Deep networks are now ubiquitous in large-scale multi-center imaging studies. However, the direct aggregation of images across sites is contraindicated for downstream statistical and deep learning-based image analysis due to inconsistent contrast, resolution, and noise. To this end, in the absence of paired data, variations of Cycle-consistent Generative Adversarial Networks have been used to harmonize image sets between a source and target domain. Importantly, these methods are prone to instability, contrast inversion, intractable manipulation of pathology, and steganographic mappings which limit their reliable adoption in real-world medical imaging. In this work, based on an underlying assumption that morphological shape is consistent across imaging sites, we propose a segmentation-renormalized image translation framework to reduce inter-scanner heterogeneity while preserving anatomical layout. We replace the affine transformations used in the normalization layers within generative networks with trainable scale and shift parameters conditioned on jointly learned anatomical segmentation embeddings to modulate features at every level of translation. We evaluate our methodologies against recent baselines across several imaging modalities (T1w MRI, FLAIR MRI, and OCT) on datasets with and without lesions. Segmentation-renormalization for translation GANs yields superior image harmonization as quantified by Inception distances, demonstrates improved downstream utility via post-hoc segmentation accuracy, and improved robustness to translation perturbation and self-adversarial attacks.

Entanglement monotones connect distinguishability and predictability

description: Distinguishability and predictability are part of complementarity relations which apply to two different kinds of interference experiments, with and without a path-detector, respectively. In [Opt. Comm. 179, 337 (2000)], Englert and Bergou pointed out the possible connection between distinguishability, predictability, and entanglement. They even conjectured that an entanglement measure was hidden between the measures of distinguishability and predictability. Here, we push forward this conjecture. We start defining a new entropic distinguishability measure and suggesting an entanglement measure as the difference between this entropic distinguishability and an entropic predictability measure already defined in the literature. Besides, we prove that it is possible to define an entanglement monotone from the largest value of the distinguishability and the corresponding predictability, provided that the predictability satisfy the criteria already established in the literature. Thus, this result formally connects an entanglement monotone with distinguishability and the corresponding predictability, without appealing to specific measures.

description: We investigate modifications of a stochastic polymer picture through a shift in the boundary between the system and an external environment. A conventional bead-and-spring model serving as the coarse-graining model is given by the Langevin equation for all the monomers subject to white noise. However, stochastic motion for only a tagged monomer is observed to occur in the presence of colored noise. The qualitative change in the observations arises from the boundary shift decided by the observer. The Langevin dynamics analyses interpret the colored noise as the emergence of the polymeric elastic force, resulting in additional heat in the tagged monomer observation. Being distinguished from coarse-graining based on scale separation, the projection of comparable internal degrees of freedom is also discussed in light of the fluctuation theorem and the stochastic polymer thermodynamics.

Pseudaganides aganiticus

description: Pseudaganides aganiticus (Schlotheim, 1820)
(Fig. 14C1-C3)
Nautilites aganiticus Schlotheim, 1820: 63. — von Loesch 1914: pl. XV (VI), fig. 1a-b.
Pseudaganides aganiticus – Marchand & Tintant 1971: 146, pl. IV, fig. 1a-b. — Jain et al. 2023: 17, fig. 14A-H.
DIAGNOSIS. — Small shells, maximum diameter about 90 mm. The umbilicus is quite small, the section is higher than wide with flat sides converging toward a narrow and rounded venter on the phragmocone. This venter flattens on the body-chamber, becoming rarely concave. Most of the time it is boarded by angular ventrolateral shoulders. Suture line with a wide and deep dissymmetric lateral lobe, lateral saddle narrow and quite short, shallow, and rounded ventral lobe.
MATERIAL EXAMINED. — France • 1 specimen (complete); Pays de la Loire, Montreuil-Bellay; [47°06’37”N, 0°06’14”W]; top of the Anceps Zone; Middle Callovian; Patrick Branger leg.; MBAN; 2023.PB.N111 (Fig. 14C1-C3).
MEASUREMENTS. — See Table 10.
DISTRIBUTION. — The oldest sample that can be attributed to this taxon has been taken from the top of the Anceps Zone, Middle Callovian. It is a common species within Upper Callovian and Lower Oxfordian (Marchand & Tintant 1971; Jain et al. 2023).
DESCRIPTION AND REMARKS
As the investigations were mainly focused on Jurassic strata from southern Deux-Sèvres, the collection is lacking in Upper Callovian examples. Nevertheless, the few Pseudaganides from these beds clearly belong to P. aganiticus (Schlotheim). This species has been revised by Marchand & Tintant (1971) and no further comment is needed. It differs from P. subbiangulatus in three major points, a more rounded section on the flanks, a smaller size (Fig. 10) and a rather closed umbilicus (Fig. 7).

description: Η κίνηση είναι συναρπαστικό μέρος της ζωής, καθώς μέσα από αυτήν τα παιδιά ανακαλύπτουν τον εαυτό τους και το περιβάλλον τους. Στα παιδιά με δυσπραξία στα οποία οι κινητικές δυσκολίες είναι κυρίαρχες, η εξερεύνηση αυτή δεν είναι τόσο ελκυστική, αφού καταναλώνουν περισσότερο χρόνο και ενέργεια για το σκοπό αυτό. Οι κινητικοί περιορισμοί έχουν αντίκτυπο στην καθημερινή τους ζωή και επιδρούν αρνητικά στην κοινωνικοσυναισθηματική τους ανάπτυξη. Στην παρούσα εργασία επιχειρείται η ψυχοδυναμική προσέγγιση της διαταραχής, με αναφορά στο σύνολο των συνειδητών και ασυνείδητων στάσεων του παιδιού για το σώμα του. Δίνεται έμφαση στην εικόνα σώματος και στο σωματικό σχήμα, καθοριστικοί παράγοντες για την κινητική συμπεριφορά του παιδιού. Πρόθεση της εργασίας είναι η θεώρηση της δυσπραξίας μέσα από μια άλλη ματιά.
description: The ability to move is a fascinating part of our lives, because it is the way in which children discover themselves and the world around them. To children suffering from dyspraxia, who have significant difficulties in their motor skills, exploring is not that appealing, since they consume more time and energy for that purpose. The limitations in their motor skills have an impact on their daily lives and negative impact on their psychosocial development. In this dissertation an attempt is made to approach this disorder through a psychodynamic approach, considering both the conscious and the unconscious experience of their body. Attention is given to the body image and body schema which are key factors to children’s motor behavior. The intention of this dissertation is to reconsider dyspraxia through another angle.

Την ίδια στιγμή, η βούληση του κρατικού καταναγκασμού να έχει λόγο για το είδος και το περιεχόμενο του κοινωνούμενου λόγου, στο πλαίσιο της λειτουργίας μιας κοινωνίας αποτέλεσε ανέκαθεν πραγματικότητα. Τόσο για λόγους γενικούς και προληπτικούς (θρησκευτικό συναίσθημα, κρατούσες αντιλήψεις περί ηθικής, δημόσια αιδώς, πολιτική ορθότητα κ.α.), όσο και για αιτίες που ανάγονται στην προστασία ανθρωπίνων δικαιωμάτων (προσωπικότητα, ανηλικότητα κ.α.) ή λόγω συνταγματικών σκοπιμοτήτων (ποιοτική στάθμη προγράμματος ραδιοτηλεόρασης, σεβασμός της αξίας του ανθρώπου κ.α.) η κρατική εξουσία θέσπιζε ανέκαθεν περιορισμούς στην συνταγματικώς κατοχυρωμένη, ως ανεπιφύλακτη, ελευθερία της Τέχνης.

description: The freedom of thinking’s and thought’s development, as well as the unobstructed freedom of expression, in the context of the social cohabitation, were always priorities for liberal states. At the same time, the state coercion’s will to have a say in the type and the context of the communicated reason, in the context of a society’s function, was always a reality. Either for general preventing reasons (religious sensitivity, holding moral beliefs, indecency, political correctness, etc.) or for causes related with the protection of human rights (personality, minority etc.) or constitutional purposes (quality of radio and television broadcasting, respect of human value etc.) the state authority has always been enacting restrictions against Freedom of Art, although it is constitutionally established without restrictions. At the same time, the markets’ and new technologies’ necessities pose additional challenges to Law and to the modern legal thought. Thus, the relationship of Art and Law within a modern democratic state is not always an easy case, as it raises problems and questions, which exceed the strict doctrine and extend upon philosophical, sociological and eventually political dimensions
Do mean-field dynamos in nonrotating turbulent shear-flows exist?

description: A plane-shear flow in a fluid with forced turbulence is considered. If the fluid is electrically-conducting then a mean electromotive force (EMF) results even without basic rotation and the magnetic diffusivity becomes a highly anisotropic tensor. It is checked whether in this case self-excitation of a large-scale magnetic field is possible (so-called WxJ-dynamo) and the answer is NO. The calculations reveal the cross-stream components of the EMF perpendicular to the mean current having the wrong signs, at least for small magnetic Prandtl numbers. After our results numerical simulations with magnetic Prandtl number of about unity have only a restricted meaning as the Prandtl number dependence of the diffusivity tensor is rather strong. If, on the other hand, the turbulence field is stratified in the vertical direction then a dynamo active alpha-effect is produced. The critical magnetic Reynolds number for such a self-excitation in a simple shear flow is slightly above 10 like for the other - but much more complicated - flow patterns used in existing dynamo experiments with liquid sodium or gallium.

A study of the applications of gainsharing incentive plans in the Canadian mining industry
Creators: name: McDonald, Douglas J.
Publisher: name: University of British Columbia
Year: 2008

description: Increased competition in the mining industry has demanded that companies focus on their operations to minimize the costs of production. While there are many strategies being used to lower costs, employee incentives that attempt to tap the human resources are becoming more prevalent. This research focuses on the applications of one of these human resources incentives in the mining industry: Gainsharing. In the mining context, gain sharing combines a group based bonus system that covers virtually all employees and is based on parameters over which they have control, with an appropriate communication network and management structure. The mining environment is conducive to gainsharing plans; in deed, gainsharing has many advantages over more commonly used incentives like piece-rate production bonuses and profit sharing plans. Currently, five percent of the operating mines in Canada use gainsharing plans, while six percent use profit sharing plans and 30% use piece-rate incentives. Surveys returned from five Canadian mines and two U.S. mines with gainsharing plans indicate that in all cases there were increases in productivity, and in all cases the mines are satisfied with the plans. However, despite the positive results, in some cases the plans are not structured and implemented in the way dictated by both experience with the plans in other industries and the characteristics of the mining industry. After thoroughly explaining the gainsharing concept and exploring the structure and results of the plans used at the mines participating in the survey, this research provides recommendations which will improve the effectiveness of gainsharing applications in mines.

description: Based on the recently formulated chiral radiation transport theory for left-handed neutrinos, we study the chiral transport of neutrinos near thermal equilibrium in core-collapse supernovae. We first compute the near-equilibrium solution of the chiral radiation transport equation under the relaxation time approximation, where the relaxation time is directly derived from the effective field theory of the weak interaction. By using such a solution, we systematically derive analytic expressions for the nonequilibrium corrections of the neutrino energy-momentum tensor and neutrino number current induced by magnetic fields via the neutrino absorption on nucleons. In particular, we find the nonequilibrium neutrino energy current proportional to the magnetic field. We also discuss its phenomenological consequences such as the possible relation to pulsar kicks.

description: It is mentioned that anyon thermodynamic potential $Q(α, N)$ could not be factorized in terms characteristic of the ideal boson $α=0$ and fermion $α=1$ gases by the relation $Q(α, N) = (1-α) Q(0, N_b)+ αQ(1, N_f)$ in which $N=N_f +N_b$, that claimed in Phys. Rev. Lett. 78, 3233 (1997). Our analyses indicate that the thermodynamic quantities of anyon gas may be factorized as $Q(α) = αQ(1) + (1-α) Q(0)$ only in the two-dimension system.

description: This review summarizes the research of Mercury's magnetosphere in the Post-MESSENGER era and compares its dynamics to those in other planetary magnetospheres, especially to those in Earth's magnetosphere. This review starts by introducing the planet Mercury, including its interplanetary environment, magnetosphere, exosphere, and conducting core. The frequent and intense magnetic reconnection on the dayside magnetopause, which is represented by the flux transfer event "shower", is reviewed on how they depend on magnetosheath plasma beta and magnetic shear angle across the magnetopause, following by how they contribute to the flux circulation and magnetosphere-surface-exosphere coupling. In the next, the progress of Mercury's magnetosphere under extreme solar events, including the core induction and the reconnection erosion on the dayside magnetosphere, the responses of the nightside magnetosphere, are reviewed. Then, the dawn-dusk properties of the plasma sheet, including the features of the ions, the structure of the current sheet, and the dynamics of magnetic reconnection, are summarized. The last topic reviews the particle energization in Mercury's magnetosphere, which includes the energization of the Kelvin-Helmholtz waves on the magnetopause boundaries, reconnection-generated magnetic structures, and the cross-tail electric field. In each chapter, the last section discusses the open questions related with each topic, which can be considered by the simulations and the future spacecraft mission. We close by summarizing the future BepiColombo opportunities, which is a joint mission between ESA and JAXA, and is en route to Mercury.

Analytical solutions for the case of two electronic bands coupled to two vibrational modes are given in detail. Within the model considered, the vector polaron can be classified by its wavefunction into several types and can have features that include: (1) a spatial variation in the electronic and vibrational character, and (2) low-energy internal degrees of freedom. For the case of electronic and vibrational degeneracy, local Jahn-Teller interactions can also lead to a novel spatiotemporal soliton, a long-lived excited state of the many-electron system stabilized by the conservation law resulting from degeneracy.

We give a reformulation of the Euler equations as a differential inclusion, and in this way we obtain transparent proofs of several celebrated results of V. Scheffer and A. Shnirelman concerning the non-uniqueness of weak solutions and the existence of energy--decreasing solutions. Our results are stronger because they work in any dimension and yield bounded velocity and pressure.

description: We study an individual-based predator-prey model of biological coevolution, using linear stability analysis and large-scale kinetic Monte Carlo simulations. The model exhibits approximate 1/f noise in diversity and population-size fluctuations, and it generates a sequence of quasi-steady communities in the form of simple food webs. These communities are quite resilient toward the loss of one or a few species, which is reflected in different power-law exponents for the durations of communities and the lifetimes of species. The exponent for the former is near -1, while the latter is close to -2. Statistical characteristics of the evolving communities, including degree (predator and prey) distributions and proportions of basal, intermediate, and top species, compare reasonably with data for real food webs.

Preaveraging description of polymer nonequilibrium stretching

Publisher: name: arXiv
Year: 2021
Subjects: subject: Soft Condensed Matter (cond-mat.soft)
subject: FOS: Physical sciences

description: This article focuses on a preaveraging description of polymer nonequilibrium stretching, where a single polymer undergoes a transient process from equilibrium to nonequilibrium steady state by pulling one chain end. The preaveraging method combined with mode analysis reduces the original Langevin equation to a simplified form for both a stretched steady state and an equilibrium state, even in the presence of self-avoiding repulsive interactions spanning a long range. However, the transient stretching process exhibits evolution of a hierarchal regime structure, which means a qualitative temporal change in probabilistic distributions assumed in preaveraging. We investigate the preaveraging method for evolution of the regime structure with consideration of the nonequilibrium work relations and deviations from the fluctuation-dissipation relation.

description: Higher-derivative corrections to cosmological effective actions in string theory are largely constrained by T-duality, but have been computed hitherto only to the first few orders in the string scale $α'$. The functional renormalization group, in conjunction with the strong constraints imposed by T-duality, allows to derive cosmological effective actions to all orders in $α'$ while avoiding "truncations" of the theory space. We show that the resulting higher-derivative $α'$-corrections forbid the existence of de Sitter vacua, at least in regimes where string-loop corrections can be neglected. Our findings thus support the implications of the no-de Sitter swampland conjecture in the presence of all-order effects in $α'$.

description: Η Μεταπτυχιακή Διπλωματική Εργασία με τίτλο Ανδρέας Καραντώνης: η συμβολή του στη δημιουργία του μύθου του Γιώργου Σεφέρη έχει ως κεντρικό άξονα μελέτης το κριτικό έργο του Ανδρέα Καραντώνη για το ποιητικό έργο του Γιώργου Σεφέρη. Η εργασία, ειδικότερα, εστιάζει αφενός σε αυτοτελείς εκδόσεις και αφετέρου στα άρθρα του στον περιοδικό τύπο της εποχής που αφορούν τις ποιητικές συλλογές και στα στοιχεία εκείνα με τα οποία κάθε φορά επιχειρεί να αναδείξει τον ποιητή σε μεγάλη μορφή των νεοελληνικών γραμμάτων. Άλλα ζητήματα που θίγονται είναι η εμπλοκή του Γιώργου Κατσίμπαλη στην καθιέρωση του ποιητή και του κριτικού στο λογοτεχνικό γίγνεσθαι, αλλά και η συνεισφορά του Καραντώνη στην πρώτη βράβευση του Σεφέρη, καθώς και οι αντιδράσεις που προκλήθηκαν εναντίον τους

description: Αντικείμενο της παρούσας διπλωματικής εργασίας είναι η πρόβλεψη των θέσεων μεθυλίωσης χρησιμοποιώντας δεδομένα αλληλούχισης επόμενης γενιάς και δεδομένα από μικροσυστοιχίες. Συγκεκριμένα, χρησιμοποιούνται δεδομένα μεθυλίωσης από δείγματα λευκών αιμοσφαιρίων. Έχοντας ως βάση το σύνολο αυτών των δεδομένων, ορίζονται τα χαρακτηριστικά γνωρίσματα που θα αποτελέσουν τη βάση της έρευνας. Τα γνωρίσματα αυτά περιλαμβάνουν τον αριθμό δινουκλεοτιδίων, τον αριθμό τρινουκλεοτιδίων, το περιεχόμενο σε δινουκλεοτίδια CG, τον αριθμό παλίνδρομων αλληλουχιών και, τέλος, τον αριθμό δομών G – quadruplexes που παρουσιάζονται εντός της αλληλουχίας που ερευνάται σε κάθε θέση. Με τη χρήση του αλγόριθμου ταξινόμησης XGBoost, κατασκευάζονται διαφορετικά μοντέλα χρησιμοποιώντας κάθε φορά ως βάση διαφορετικές παραμέτρους και διαφορετικά υποσύνολα χαρακτηριστικών γνωρισμάτων. Τα διαφορετικά αυτά υποσύνολα προκύπτουν μέσα από τη σπουδαιότητα του κάθε γνωρίσματος σύμφωνα με τις επιδόσεις του αλγορίθμου XGBoost, καθώς και από τα αποτελέσματα μίας μεθόδου επιλογής χαρακτηριστικών που βασίζεται στα Τυχαία Δάση, του αλγόριθμου Boruta. Τα αποτελέσματα της έρευνας αποδεικνύουν πως τα χαρακτηριστικά γνωρίσματα που έχουν επιλεγεί είναι ικανά να δημιουργήσουν ισχυρά μοντέλα πρόβλεψης των θέσεων μεθυλίωσης στο ανθρώπινο γονιδίωμα. Συγκεκριμένα, το προτεινόμενο μοντέλο παρουσιάζει ακρίβεια που αγγίζει το 88,08% σε ένα σύνολο 298.639 δεδομένων. Η συγκεκριμένη επίδοση είναι αρκετά ικανοποιητική ενώ αποτελεί ταυτόχρονα βάση για περαιτέρω έρευνα και ανάπτυξη τόσο σε διαφορετικά σύνολα δεδομένων όσο και μέσω της χρήσης επιπλέον, νέων χαρακτηριστικών γνωρισμάτων.
description: The subject of this thesis is the prediction of methylation sites using next-generation sequencing and microarray data from white blood cell samples. Based on these data, the features that will form our study are defined: the number of dinucleotides, the number of trineucleotides, the content of CG dinucleotides, the number of palindromic sequences, and, finally, the number of G-quadruplexes structures within every sequence. Thus, using the XGBoost classification method, different models are constructed using different parameters and subsets of features. These subsets are constructed based on the feature importance and feature selection with XGBoost and the Boruta algorithm, a wrapper method built around the Random Forest classification algorithm. The results of this thesis indicate that the selected features can lead to strong classification models for the prediction of DNA methylation sites in the human genome. Specifically, the proposed model has a 88.08% classification accuracy in a total of 298.639 data.

description: Atomic response to a probe beam can be tailored, by creating coherences between atomic levels with help of another beam. Changing parameters of the control beam will change the nature of coherences and hence the nature of atomic response as well. Such change can depend upon intensity of both probe and control beams, in a nonlinear fashion. We present a situation where this nonlinearity in dependence can be precisely controlled, as to obtain different variations as desired. We also present a detailed analysis of how this nonlinear dependency arises and show that this is an interesting effect of several Coherent Population Trap(CPT) states that exist and a competition among them to trap atomic population in them.

description: We study phase-dependent fluctuations of the resonance fluorescence of a single $Λ$-type three-level atom in the regime near coherent population trapping, i.e., alongside the two-photon detuning condition. To this end, we employ the method of conditional homodyne detection (CHD) which considers squeezing in the weak driving regime, and extends to non-Gaussian fluctuations for saturating and strong fields. In this framework, and using estimated parameter settings of the resonance fluorescence of a single trapped $^{138} \mathrm{Ba}^{+}$ ion, the light scattered from the probe transitions is found to manifest a non-classical character and conspicuous asymmetric third-order fluctuations in the amplitude-intensity correlation of CHD.

description: Network slicing is one of the main differentiating and innovative features of 5G by enabling the partitioning of the network infrastructure to support specific use cases, services, individual customers or vertical industries. This feature will be implemented, evaluated and validated by the 5G-VINNI end-to-end Facility though the deployment of a wide range of 5G trials, according to the requirements defined by end users. This document is focused on operation, management and orchestration of network slicing and draws upon the current state of the art in standardization and R&D projects, as well as two previous 5G-VINNI deliverables, D1.1 and D1.2.

description: The observation and modeling of natural Complex Systems (CSs) like the human nervous system, the evolution or the weather, allows the definition of special abilities and models reusable to solve other problems. For instance, Genetic Algorithms or Ant Colony Optimizations are inspired from natural CSs to solve optimization problems. This paper proposes the use of ant-based systems to solve various problems with a non assessing approach. This means that solutions to some problem are not evaluated. They appear as resultant structures from the activity of the system. Problems are modeled with graphs and such structures are observed directly on these graphs. Problems of Multiple Sequences Alignment and Natural Language Processing are addressed with this approach.

The role of expert systems in supervisory control applications
Creators: name: Benford, Paul Michael
Publisher: name: University of British Columbia

description: The development of control systems that incorporate aspects of Artificial Intelligence into their strategy has become a reality for engineering and manufacturing companies. Expert systems, as a branch of AI technology have attained a foothold in real-time control and in doing so have established credibility through many successfully engineered applications. When applying AI to control and monitoring systems, a developer must use new ways to acquire and represent process knowledge. Knowledge Engineering, a new field of Engineering, requires proficiency in the techniques of interviewing experts, guiding experts in their discussions and representing the knowledge gleaned from such interviews into statements in a rule base of procedural code. The approach to knowledge acquisition and some of the pitfalls involved in developing expert systems for real-time control and monitoring are discussed. The descriptions of two leading expert system packages, Comdale/X© and Comdale/C©, are given with case examples, in order to show the development steps and potential benefits of this technology.
A measurement of two-photon exchange in Super-Rosenbluth separations with positron beams

description: The proton electric and magnetic form factors, $G_E$ and $G_M$, are intrinsically connected to the spatial distribution of charge and magnetization in the proton. For decades, Rosenbluth separation measurements of the angular dependence of elastic e$^-$-p scattering were used to extract $G_E$ and $G_M$. More recently, polarized electron scattering measurements, aiming to improve the precision of $G_E$ extractions, showed significant disagreement with Rosenbluth measurements at large momentum transfers ($Q^2$). This discrepancy is generally attributed to neglected two-photon exchange (TPE) corrections. At larger $Q^2$ values, a new `Super-Rosenbluth' technique was used to improve the precision of the Rosenbluth extraction, allowing for a better quantification of the discrepancy, while comparisons of e$^+$-p and e$^-$-p scattering indicated the presence of TPE corrections, but at $Q^2$ values below where a clear discrepancy is observed. In this work, we demonstrate the significant benefits to combining the Super-Rosenbluth technique with positron beam measurements. This approach provides a greater kinematic reach and is insensitive to some of the key systematic uncertainties in previous positron measurements.

description: While near-zero thermal expansion (NZTE) in YbGaGe is sensitive to stoichiometry and defect concentration, the NZTE mechanism remains elusive. We present x-ray absorption spectra that show unequivocally that Yb is nearly divalent in YbGaGe and the valence does not change with temperature or with nominally 1% B or 5% C impurities, ruling out a valence-fluctuation mechanism. Moreover, substantial changes occur in the local structure around Yb with B and C inclusion. Together with inelastic neutron scattering measurements, these data indicate a strong tendency for the lattice to disorder, providing a possible explanation for NZTE in YbGaGe.

description: We study the prospect of determining the decay properties of the gluino in the supersymmetric (SUSY) standard model at a 100 TeV future hadron collider. We consider the case where the neutral Wino is the lightest superparticle. In this case, the long-lived charged Wino can be used to eliminate standard model backgrounds, which enables us to study the details of superparticles. We show that, based on the analysis of the numbers of high $p_T$ leptons, boosted $W$-jets, and $b$-tagged jets, we may determine the gaugino species and the quark flavors in the gluino decay. With such determinations, we can obtain information about the mass spectrum of squarks even if squarks are out of the kinematical reach.

description: The rate of change of entropy $\dot S$ is measured for a system of particles floating on the surface of a fluid maintained in a turbulent steady state. The resulting coagulation of the floaters allows one to relate $\dot S$ to the velocity divergence and to the Lyapunov exponents characterizing the behavior of this system. The quantities measured from experiments and simulations are found to agree well with the theoretical predictions.

description: We analyze the "vacuum" polarization induced by a quantum charged scalar field near the inner horizon of a charged (Reissner-Nordström-de Sitter) black hole in quantum states that start out as regular states near an initial Cauchy surface. Contrary to the outer (i.e. event-) horizon, where polarization effects lead to a discharge, we find that near an inner horizon, the transversal component of the expected current density can have either sign depending on the black hole and field parameters. Thus, the inner horizon can be charged or discharged. But we find that it is always discharged close to extremality thus driving the black hole interior away from this critical point. Furthermore, we find that quantum effects dominate in that the strength of the blow up of the quantum current at the inner horizon is state-independent and stronger than that of the current of a classical solution.
