Mechanisms of biological control of crown and root rot in tomato by a nonpathogenic Fusarium oxysporum strain
Creators: name: Sircom, Katharine M.
Publisher: name: University of British Columbia
Year: 2008

description: The biological control of crown and root rot in tomato was studied in a sterile system in which tomato seedlings were grown on water agar in petri plates or on filter wicks in test tubes containing fertilizer solution. The biological control agent, nitBl, was a nonpathogenic strain of Fusarium oxysporum which had been mutated to a nitrate non-utilizing form in order to distinguish it from the pathogen, Fusarium oxysporum f. sp.radicis-lycopersici (FORL). Four different approaches were used to deduce possible mechanisms of control. One approach was to study the effect of inoculum timing and inoculum density on biological control. Biological control was demonstrated when nit B1 was inoculated to the roots as much as 21 days before FORL, and persisted for at least 23 days after the FORL inoculation. When nit B1 was inoculated to seedling roots at least 3 days before FORL, there was good disease control even when the initial inoculum density of nit B1 was 60 times lower than that of FORL. As the lag between inoculations decreased, higher densities of nit B1 were needed to bring about control, and when the two fungi were inoculated simultaneously the inoculum density of nit B1 had to be at least 10 times that of FORL for there to be any reduction of disease symptoms. The second approach was to observe the colonization of seedling roots by the two strains. Both nit B1 and FORL colonized the outer layers of the root. However, when nit B1 was inoculated to the root 4 days before FORL, the rate of increase of nit B1 was greater than the rate of increase of FORL. The third approach was to test possible elicitors of a defence reaction in tomato for their biological control ability. Sterile filtrates from cultures of nit B1 grown in nutrient broth, sterile exudates from nit B1-infested germinating seeds and seedling roots, heat-killed nit B1 spores, and the cell wall fraction from nit B1 all failed to protect seedlings against crown and root rot induced by FORL. The fourth approach was to test nutrient competition by adding an excess of nutrients that might otherwise be limiting. Biological control by nit B1 was not affected when excess glucose or iron were added to the growth medium. In a related experiment, FORL caused severe disease symptoms (in the absence of nit B1) even when iron availability was artificially decreased by adding a strong iron chelator to the growth medium. The conclusion from all these experiments was that nit B1may elicit a defense response in tomato roots, possibly dependent on the prior colonization of the roots by this strain, which makes the roots resistant to subsequent infection by FORL.

description: La traduzione poetica viene affrontata sul piano empirico dell'analisi testuale.
Una breve introduzione presenta le riflessioni più importanti sulla traduzione del testo poetico, da Benjamin e Steiner fino alle teorie più recenti di Meschonnic, Apel, Berman e Mattioli. Alla luce di queste teorie vengono analizzate le opere di due coppie di poeti e poeti-traduttori. Nel primo esempio troviamo il poeta svizzero (francofono) Philippe Jaccottet alle prese con l'intera opera di Ungaretti; nel secondo il rapporto travagliato di Vittorio Sereni con la poesia di René Char.
Oltre a indagare la natura problematica della traduzione poetica come pratica e come esperienza, questa tesi di Letteratura Comparata vuole presentare la traduzione come strumento ermeneutico e come meccanismo rienunciativo: il suo ruolo nella dialettica delle influenze e dell'evoluzione letteraria è da considerarsi infatti essenziale. La vocazione originariamente etica della traduzione è sfondo costante della trattazione.
description: Poetic translation is faced on the empirical level of textual analysis.
A short introduction presents some main theories about poetic translation, from Benjamin and Steiner till more recent experts: Meschonnic, Apel, Berman and Mattioli. Following these thoughts, the works of two couples of poets and translators are analyzed. In the first case Philippe Jaccottet will be dealing with the entire Ungaretti's poetic production; in the second example, the translating intent of Vittorio Sereni on René Char's poems is described.
While investigating the complex nature of poetic translation as a practice and an experience, this thesis in Compared Literature tries to present translation as an hermeneutic tool and a re-enunciating mechanism: its role in the dialectic movement of influences and literary evolutions is considered as essential. The original ethical vocation of translation is a constant background of the research.

description: We present two fast algorithms which apply inclusion-exclusion principle to sum over the bosonic diagrams in bare diagrammatic quantum Monte Carlo (dQMC) and inchworm Monte Carlo method, respectively. In the case of inchworm Monte Carlo, the proposed fast algorithm gives an extension to the work ["Inclusion-exclusion principle for many-body diagrammatics", Phys. Rev. B, 98:115152, 2018] from fermionic to bosonic systems. We prove that the proposed fast algorithms reduce the computational complexity from double factorial to exponential. Numerical experiments are carried out to verify the theoretical results and to compare the efficiency of the methods.

description: L’obiettivo di questa tesi è rilevare se e quanto i medical dramas abbiano contribuito a ridefinire conoscenze, aspettative e pratiche dei telespettatori/pazienti rispetto a questioni concernenti la salute e il loro ruolo all’interno della relazione medico-paziente. Grazie ad un lavoro di campo, fatto di questionari e interviste con utenti, operatori della sanità di Centro e Nord Italia e studenti di Medicina, sono state poi registrate le modalità di interazione che i protagonisti della scena della cura dichiarano di sperimentare quotidianamente. Ciò ha permesso di rendere conto delle trasformazioni più recenti della professione medica e di come viene elaborato oggi il sapere sulla malattia da parte dei soggetti implicati, fra tecnicismi, atteggiamenti difensivi, sfiducia e affidamento. La tesi restituisce anche alcune modalità sperimentali di interazione fra pazienti e medici, messe in atto in contesti locali, che testimoniano l’esigenza di approdare a un sapere partecipato delle relazioni di cura. Infine, raccogliendo la sfida posta dalle medical humanities, immagina un utilizzo del medical drama nella formazione degli studenti di medicina per l’apprendimento di competenze narrative necessarie ad una pratica medica più umana e efficace.
description: The aim of this thesis is to identify whether and to what degree medical dramas have contributed to redefine TV viewers/patients’ knowledge, expectations, and practices with regard to health-related issues and their role in the doctor-patient relationship. The fieldwork, conducted through questionnaires and interviews with users, medical students and health professionals from Central and Northern Italy, has revealed the interactional modes the key players in medical care declare to experience in everyday life. This has made it possible to access the most recent transformations within the medical profession and the way the involved actors acquire knowledges about illness, amidst technical jargon, defensive behaviours, mistrust and entrustment. Moreover, the thesis offers insight into some experimental modes of interaction between patients and physicians taking place in local contexts, revealing the need to achieve participatory understandings of health care relationships. Finally, embracing the challenge posed from the medical humanities, it conceives of medical dramas as a training tool for medical students to acquire the narrative competence necessary to a more human and effective medical practice.

description: Federated Learning (FL) is a technique that allows multiple parties to train a shared model collaboratively without disclosing their private data. It has become increasingly popular due to its distinct privacy advantages. However, FL models can suffer from biases against certain demographic groups (e.g., racial and gender groups) due to the heterogeneity of data and party selection. Researchers have proposed various strategies for characterizing the group fairness of FL algorithms to address this issue. However, the effectiveness of these strategies in the face of deliberate adversarial attacks has not been fully explored. Although existing studies have revealed various threats (e.g., model poisoning attacks) against FL systems caused by malicious participants, their primary aim is to decrease model accuracy, while the potential of leveraging poisonous model updates to exacerbate model unfairness remains unexplored. In this paper, we propose a new type of model poisoning attack, EAB-FL, with a focus on exacerbating group unfairness while maintaining a good level of model utility. Extensive experiments on three datasets demonstrate the effectiveness and efficiency of our attack, even with state-of-the-art fairness optimization algorithms and secure aggregation rules employed.

description: In a seminal paper, Page found the exact formula for the average entanglement entropy for a pure random state. We consider the analogous problem for the ensemble of pure fermionic Gaussian states, which plays a crucial role in the context of random free Hamiltonians. Using recent results from random matrix theory, we show that the average entanglement entropy of pure random fermionic Gaussian states in a subsystem of $N_A$ out of $N$ degrees of freedom is given by $\langle S_A\rangle_\mathrm{G}\!=\!(N\!-\!\tfrac{1}{2})Ψ(2N)\!+\!(\tfrac{1}{4}\!-\!N_A)Ψ(N)\!+\!(\tfrac{1}{2}\!+\!N_A\!-\!N)Ψ(2N\!-\!2N_A)\!-\!\tfrac{1}{4}Ψ(N\!-\!N_A)\!-\!N_A$, where $Ψ$ is the digamma function. Its asymptotic behavior in the thermodynamic limit is given by $\langle S_A\rangle_\mathrm{G}\!=\! N(\log 2-1)f+N(f-1)\log(1-f)+\tfrac{1}{2}f+\tfrac{1}{4}\log{(1-f)}\,+\,O(1/N)$, where $f=N_A/N$. Remarkably, its leading order agrees with the average over eigenstates of random quadratic Hamiltonians with number conservation, as found by Lydzba, Rigol and Vidmar. Finally, we compute the variance in the thermodynamic limit, given by the constant $\lim_{N\to\infty}(ΔS_A)^2_{\mathrm{G}}=\frac{1}{2}(f+f^2+\log(1-f))$.

description: New BVRI photometry and optical spectroscopy of the Type IIp supernova 2004dj in NGC 2403, obtained during the first year since discovery, are presented. The progenitor cluster, Sandage 96, is also detected on pre-explosion frames. The light curve indicates that the explosion occured about 30 days before discovery, and the plateau phase lasted about +110 \pm 20 days after that. The plateau-phase spectra have been modelled with the SYNOW spectral synthesis code using H, NaI, TiII, ScII, FeII and BaII lines. The SN distance is inferred from the Expanding Photosphere Method and the Standard Candle Method applicable for SNe IIp. They resulted in distances that are consistent with each other as well as earlier Cepheid- and Tully-Fisher distances. The average distance, D = 3.47 \pm 0.29 Mpc is proposed for SN 2004dj and NGC 2403. The nickel mass produced by the explosion is estimated as 0.02 \pm 0.01 M_o. The SED of the progenitor cluster is reanalysed by fitting population synthesis models to our observed BVRI data supplemented by U and JKH magnitudes from the literature. The chi^2-minimization revealed a possible "young" solution with cluster age T_{cl} = 8 Myr, and an "old" solution with T_{cl} = 20 - 30 Myr. The "young" solution would imply a progenitor mass M > 20 M_o, which is higher than the previously detected progenitor masses for Type II SNe.

description: Objectifs À l’heure actuelle, l’obésité est en augmentation dans les pays industrialisés. Ainsi, nous rencontrons de plus en plus de femmes présentant une obésité dans le milieu des soins. Cette obésité peut engendrer des difficultés dans la santé materno-foetale, notamment lors de l’allaitement. Ainsi, notre objectif principal est de comprendre les attentes des femmes et des soignants. En découle notre second objectif, qui est de pouvoir proposer une prise en soins satisfaisante pour les femmes et les professionnels de santé, en nous basant sur la littérature scientifique et nos expériences professionnelles. Méthodologie Nous avons tenté d’apporter des pistes de réflexion à ce sujet d’actualité à l’aide d’une revue de littérature composée de huit articles. Ces articles sont quantitatifs et qualitatifs en lien avec notre sujet qui traite de prises en soin de l’allaitement chez les femmes présentant une obésité, mais aussi du ressenti des femmes et des professionnels de santé. Principaux résultats Nous avons pu mettre en évidence que de nombreux professionnels de santé ne connaissent pas les difficultés spécifiques rencontrées lors de l’allaitement par les femmes présentant une obésité. Les femmes quant à elle décrivent des obstacles réels à l’allaitement et un soutien perçu comme inadapté. Des pistes de réflexion sur l’amélioration de la pratique soignante auprès de cette population ont pu être mises en avant et ouvrir vers des actions concrètes à apporter aux femmes. Conclusion Le soutien centré sur la femme semble être une des clés de la réussite de l’allaitement chez cette population. Cependant, d’autres recherches sont nécessaires afin d’offrir des pistes de compréhension du phénomène étudié et de permettre aux professionnels d’ajuster leurs connaissances et de développer des outils d’aide concrets.

description: This research aims to identify the guidelines that are opposed to Judaism in the body of the work Dialogue with Trypho of Justin Martyr, using the methodology engendered by Norbert Elias and John L. Scotson in their work, The Established and the Outsiders. As a result, our research intends to contribute to unveil another aspect of Justin’s work, considered by many scholars as a proselytistic tool; by taking it as a document builder of the Christian identity trough its dissociation from Judaism. For this reason, this thesis investigates and reviews the socio-cultural and political environment that gave rise to Roman Christianity, taking into consideration Christian internal conflicts and the resulting dichotomies within the Roman Christian community, as a result of its departure from its Jewish matrix.
The universal shear conductivity of Fermi liquids and spinon Fermi surface states and its detection via spin qubit noise magnetometry

description: We demonstrate a remarkable property of metallic Fermi liquids: the transverse conductivity assumes a universal value in the quasi-static ($ω\rightarrow 0$) limit for wavevectors $q$ in the regime $l_{\rm mfp}^{-1} \ll q \ll p_{\rm F}$, where $l_{\rm mfp}$ is the mean free path and $p_{\rm F}$ is the Fermi momentum. This value is $(e^2/h) \mathcal{R}_{\rm FS}/q$ in two dimensions (2D), where $\mathcal{R}_{\rm FS}$ measures the local radius of curvature of the Fermi surface in momentum space. Even more surprisingly, we find that U(1) spin liquids with a spinon Fermi surface have the same universal transverse conductivity. This means such spin liquids behave effectively as metals in this regime, even though they appear insulating in standard transport experiments. Moreover, we show that transverse current fluctuations result in a universal low-frequency magnetic noise that can be directly probed by a spin qubit, such as a nitrogen-vacancy center in diamond, placed at a distance $z$ above of the 2D metal or spin liquid. Specifically the magnetic noise is given by $Cω\mathcal{P}_{\rm FS}/z$, where $\mathcal{P}_{\rm FS}$ is the perimeter of the Fermi surface in momentum space and $C$ is a combination of fundamental constants of nature. Therefore these observables are controlled purely by the geometry of the Fermi surface and are independent of kinematic details of the quasi-particles, such as their effective mass and interactions. This behavior can be used as a new technique to measure the size of the Fermi surface of metals and as a smoking gun probe to pinpoint the presence of the elusive spinon Fermi surface in two-dimensional systems. We estimate that this universal regime is within reach of current nitrogen-vacancy center spectroscopic techniques for several spinon Fermi surface candidate materials.

description: The star CD-42o11721 is a curious B[e] star sometimes pointed as an evolved B[e] supergiant and sometimes as a young HAeBe star, due to very uncertain or even unknown stellar parameters, especially the distance. In this paper, we present new data gained from high-resolution optical spectroscopy and a detailed description of IR data of this star. We present a qualitative study of the numerous emission lines in our optical spectra and the classification of their line profiles, which indicate a non-spherically symmetric circumstellar environment. The first real detection of numerous [Fe II] emission lines and of many other permitted and forbidden emission lines is reported. From our optical data, we derive an effective temperature of 14000 K, a radius of 17.3 +/- 0.6 Rsun, as well as a luminosity of 1.0 +/- 0.3 x 10^{4} Lsun. We advocate that CD-42o11721 might be a post-main sequence object, even though a pre-main sequence nature cannot be ruled out due to the uncertain distance. We further found that the SED in the optical and infrared can best be fitted with an outflowing disk-forming wind scenario rather than with a spherical symmetric envelope or with a flared disc, supporting our tentative classification as a B[e] supergiant.

description: The purpose of the first part of the research activity was to develop an aerobic cometabolic process in packed bed reactors (PBR) to treat real groundwater contaminated by trichloroethylene (TCE) and 1,1,2,2-tetrachloroethane (TeCA). In an initial screening conducted in batch bioreactors, different groundwater samples from 5 wells of the contaminated site were fed with 5 growth substrates. The work led to the selection of butane as the best growth substrate, and to the development and characterization from the site’s indigenous biomass of a suspended-cell consortium capable to degrade TCE with a 90 % mineralization of the organic chlorine. A kinetic study conducted in batch and continuous flow PBRs and led to the identification of the best carrier. A kinetic study of butane and TCE biodegradation indicated that the attached-cell consortium is characterized by a lower TCE specific degredation rates and by a lower level of mutual butane-TCE inhibition. A 31 L bioreactor was designed and set up for upscaling the experiment.
The second part of the research focused on the biodegradation of 4 polymers, with and with-out chemical pre-treatments: linear low density polyethylene (LLDPE), polyethylene (PP), polystyrene (PS) and polyvinyl chloride (PVC). Initially, the 4 polymers were subjected to different chemical pre-treatments: ozonation and UV/ozonation, in gaseous and aqueous phase. It was found that, for LLDPE and PP, the coupling UV and ozone in gas phase is the most effective way to oxidize the polymers and to generate carbonyl groups on the polymer surface. In further tests, the effect of chemical pretreatment on polyner biodegrability was studied. Gas-phase ozonated and virgin polymers were incubated aerobically with: (a) a pure strain, (b) a mixed culture of bacteria; and (c) a fungal culture, together with saccharose as a co-substrate.

description: We present a theoretical study of the equilibrium ordering in a 3D XY nematic system with quenched random disorder. Within this model, treated with the replica trick and Gaussian variational method, the correlation length is obtained as a function of the local nematic order parameter and the effective disorder strength. These results clarify what happens in the limiting cases of diminishing order parameter and disorder strength, that is near a phase transition of a pure system. In particular, it is found that quenched disorder is irrelevant as the order parameter tends to zero and hence does not change the character of the continuous XY nematic to isotropic phase transition. We discuss how these results compare with experiments and simulations

description: The EyeSight feature, introduced with the new Apple Vision Pro XR headset, promises to revolutionize user interaction by simulating real human eye expressions on a digital display. This feature could enhance XR devices' social acceptability and social presence when communicating with others outside the XR experience. In this pilot study, we explore the implications of the EyeSight feature by examining social acceptability, social presence, emotional responses, and technology acceptance. Eight participants engaged in conversational tasks in three conditions to contrast experiencing the Apple Vision Pro with EyeSight, the Meta Quest 3 as a reference XR headset, and a face-to-face setting. Our preliminary findings indicate that while the EyeSight feature improves perceptions of social presence and acceptability compared to the reference headsets, it does not match the social connectivity of direct human interactions.

description: The fake supergravity method is applied to 5-dimensional asymptotically AdS spacetimes containing gravity coupled to a real scalar and an abelian gauge field. The motivation is to obtain bulk solutions with R x S^3 symmetry in order to explore the AdS/CFT correspondence when the boundary gauge theory is on R x S^3. A fake supergravity action, invariant under local supersymmetry through linear order in fermion fields, is obtained. The gauge field makes things more restrictive than in previous applications of fake supergravity which allowed quite general scalar potentials. Here the superpotential must take the form W(ϕ) ~ exp(-kϕ) + c exp(2ϕ/(3k)), and the only freedom is the choice of the constant k. The fermion transformation rules of fake supergravity lead to fake Killing spinor equations. From their integrability conditions, we obtain first order differential equations which we solve analytically to find singular electrically charged solutions of the Lagrangian field equations. A Schwarzschild mass term can be added to produce a horizon which shields the singularity. The solutions, which include "superstars", turn out to be known in the literature. We compute their holographic parameters.

description: Πραγματοποιήθηκαν τέσσερα in vivo πειράματα πεπτικότητας και ένα πείραμα συγκριτικής διατροφής. Το ένα πείραμα πεπτικότητας ήταν σύνθετο και είχε σκοπό τον προσδιορισμό των συντελεστών πεπτικότητας πέντε πρωτεϊνικών πηγών, με τη μέθοδο διαφοράς, σε ένα σχέδιο λατινικού τετραγώνου 5Χ5. Τα τρία υπόλοιπα πειράματα πεπτικότητας είχαν ως σκοπό την αξιολόγηση της επίδρασης των παραπάνω πρωτεϊνικών πηγών στην πεπτικότητα των θρεπτικών συστατικών, στον ισολογισμό Ν και ενέργεια των σιτηρεσίων όπου αυτές συμμετέχουν. Τα συμπέρασμα από τα πειράματα πεπτικότητας είναι ότι η αύξηση της περιεκτικότητας σε μη αποδομήσιμη πρωτεϊνη δεν επηρεάζει την πεπτικότητα, τον ισολογισμό Ν και ενέργειας των σιτηρεσίων. Το πείραμα συγκριτικής διατροφής πραγματοποιήθηκε με τη χρήση 42 προβατικών της φυλής χίου κατά την εναρκτήρια φάση γαλακτοπαραγωγής, με σκοπό την αξιολόγηση της αύξησης σε μη αποδομήσιμη πρωτεϊνη, με ή χωρίς την προσθήκη συνθετικής λυσίνης, στα παραγωγικά χαρακτηριστικά. Η προσθήκη λυσίνης αυξάνει την ημερήσια παραγωγή πρωτεϊνης του γάλακτος
description: Four in vivo digestibility trials and an comparative lactating trial were conducted. The first digestibility trial aimed to measure, by difference, digestibility coefficients of five protein sources by the use of an 5x5 latin square design. The purpose of the other three digestion trials was to evaluate the effects, on nutrient digestibility, N and energy balance of sheep rations, of these protein sources. An 50% increase of rumen undergradable protein content(RUP) of the diet didn't negatively affect diet's nutrient digestibility nor energy and N balance. In the comparative lactating trial, forty two multiparous chios breed ewes were examined in a 8-wk study(repeated measures). The purpose of this study was to evaluate the effects of RUP content of the diet with or without additional lysine on milk yield and composition. Lysine have increased daily milk protein yield

Η εν λόγω διατριβή αφορά τη χρήση του θησαυρού όρων wordnet για την ακριβέστερη απόδοση της έννοιας των λέξεων μέσα στο περιεχόμενο στο οποίο απαντώνται αλλά και την αποτελεσματικότερη πρόσβαση σε πληροφορία με την τμηματοποίηση μεγάλης έκτασης κειμένων σε μικρότερα. Πιο συγκεκριμένα προτείνει τρία μοντέλα. Το πρώτο πραγματοποιεί κατηγοριοποίηση κειμένων με τη βοήθεια της έννοιας της κάθε λέξης και όχι των αυτούσιων λέξεων του εκιμένου. Το δεύτερο μοντέλο πραγματεύεται την τμηματοποίηση κειμένων με τη βοήθεια τεχνικών κατηγοριοποίησης κειμένων. Τέλος το 3ο μοντέλο υλοποιεί ένα μοντέλο τμηματοποίηση κειμένων μεγάλης έκτασης σε μικρότερα, καθένα από τα οποία παρουσιάζει ισχυρή συνάφεια και συνοχή σε τοπικό επίπεδο. Η εν λόγω τμηματοποίηση πραγματοποιείται ως συνδυασμός εύρεσης της ομοιότητας μεταξύ των μερών του κειμένου και αυτόματου καθορισμού των ορίων των τμημάτων. Η επιτυχία των μοντέλων επιβεβαιώνεται από την εφαρμογή τους σε αντίστοιχα σώματα κειμένων με σημαντικότερο αυτό που περιέχει ελληνικά κείμανα
description: This dissertation deals with the development of computational methods which penetrate into the context of texts and reveal their structure as the result of finding their topics and subtopics. The benefit of such methods is the improvement in accessing in information using a language technology. This dissertation uses Wordnet's thesaurous in order to attribute the sense of a word taking under consideration the content in which this word appears in the text. The dissertation proposes and implements three models. The first of those classifies texts using the apropriate sense of the texts. The second model implements text segmentation using the outcome of classification. Finally, the third model suggests a method for segmenting large texts into smaller segments, each of which exhibiting strong cohesion and coherence in a topical level. The afore mentioned segmentation is realized by the combination of a technique which calculates the similarity between parts of a text and a technique which automatically determines segment boundouries. The success of afore mentioned model was validated after their evaluation in on important number of datasets the most important of which consists texts

description: The phase-integral approximation devised by Fröman and Fröman, is used for computing cosmological perturbations in the power-law inflationary model. The phase-integral formulas for the scalar and tensor power spectra are explicitly obtained up to ninth-order of the phase-integral approximation. We show that, the phase-integral approximation exactly reproduces the shape of the power spectra for scalar and tensor perturbations as well as the spectral indices. We compare the accuracy of the phase-integral approximation with the results for the power spectrum obtained with the slow-roll and uniform approximation methods.

description: We classify the geometry of all supersymmetric IIB backgrounds which admit the maximal number of $G$-invariant Killing spinors. For compact stability subgroups $G=G_2, SU(3)$ and SU(2), the spacetime is locally isometric to a product $X_n\times Y_{10-n}$ with $n=3,4,6$, where $X_n$ is a maximally supersymmetric solution of a $n$-dimensional supergravity theory and $Y_{10-n}$ is a Riemannian manifold with holonomy $G$. For non-compact stability subgroups, $G=K\ltimes\bR^8$, $K=Spin(7)$, SU(4), $Sp(2)$, $SU(2)\times SU(2)$ and $\{1\}$, the spacetime is a pp-wave propagating in an eight-dimensional manifold with holonomy $K$. We find new supersymmetric pp-wave solutions of IIB supergravity.

Refined Astrometry and Positions for 179 Swift X-ray Afterglows

description: We present a refined catalog for the positions of 179 Gamma-ray burst (GRB) X-ray afterglows observed by the X-ray Telescope (XRT) on Swift prior to November 1, 2006. The positions are determined by detecting X-ray field sources in the deep X-ray images and comparing the centroids to those of optical sources in the Digitized Sky Survey (DSS) red2 catalog or the Sloan Digital Sky Survey (SDSS) DR-5 catalog. Half of the 90% confidence error region radii are <2.2 arcseconds. The error regions areas are typically ~4 times smaller than the best XRT-team error regions, although the positions require deep X-ray integration (>20 ksec) and cannot be generated nearly as rapidly after the GRB. The positions derived for >90% of 77 bursts with optical afterglows are consistent with the optical transient positions, without the need for systematic error. About 20% of the afterglows positions require a sizable shift in the Swift satellite aspect. We discuss the optical/X-ray properties of the field sources and discuss implications of the frame offsets for studies of optically dark GRBs.

description: Motor proteins are active enzyme molecules that play a crucial role in many biological processes. They transform the chemical energy into the mechanical work and move unidirectionally along rigid cytoskeleton filaments. Single-molecule experiments suggest that motor proteins, consisting of two motor domains, move in a hand-over-hand mechanism when each subunit changes between trailing and leading positions in alternating steps, and these subunits do not interact with each other. However, recent experiments on heterodimeric kinesins suggest that the motion of motor domains is not independent, but rather strongly coupled and coordinated, although the mechanism of these interactions are not known. We propose a simple discrete stochastic model to describe the dynamics of homodimeric and heterodimeric two-headed motor proteins. It is argued that interactions between motor domains modify free energy landscapes of each motor subunit, and motor proteins still move via the hand-over-hand mechanism but with different transitions rates. Our calculations of biophysical properties agree with experimental observations. Several ways to test the theoretical model are proposed.
