description: Σκοπός της εργασίας ήταν η μελέτη των βίων των δια Χριστόν σαλών από δογματική πλευρά. Εξετάσαμε την ορολογία της σαλότητας και της μωρίας στην Αγία Γραφή και ιδιαίτερα στο απόστολο Παύλο και κατά τους Πατέρες της Εκκλησίας, κάποιοι από αυτούς είχαν κάποιες αντιρρήσεις και ειδικά στους ψευδοσαλούς. Στη συνέχεια μελετήσαμε τις δογματικές προϋποθέσεις των Σαλών, παρουσιάσαμε αναλυτικά την βιωμένη διδασκαλία τους, την Θεολογία: πίστη, απάθεια, την Πνευματολογία: φωτισμός, κλήση, την Χριστολογία: μίμηση του Χριστού, Ενσάρκωση, την Ανθρωπολογία: θέωση, ελευθερία του προσώπου, την Εκκλησιολογία: λατρεία έμψυχη της καρδιάς και την Εσχατολογία: έρχεται από τα έσχατα να εγκαινιάσει το παρόν. Ασχοληθήκαμε επιπλέον με την έννοια της αγιότητας γενικά και την αγιότητα των Σαλών ειδικά, και εξετάσαμε την αναγνώριση αγιότητας και ιδιαίτερα πως αναγνώρισε η Εκκλησία την αγιότητα τέτοιων δια Χριστόν σαλών ως αγίων μεταξύ των λοιπών αγίων της. Συμπεράναμε τελικά ότι όντως αυτοί οι άγιοι είχαν μες στην ζωή τους το δογματικό υπόβαθρο σύμφωνα με την διδασκαλία της Εκκλησίας.
description: The aim of the present thesis was the study of biographies of the holy fools for Christ from doctrinal side. We examined the proposed terminology and the definitions of holy foolishness, salos, moria, in the Bible, especially in the Apostle Paul’s letters, in the writings of the Church’s Fathers, some of those had certain objections, particularly with the false fools, or pseudosaloi. Then we presented the dogmatic preconditions of the Holy Fools. Furthermore, we analyzed theirs experimental teaching: about Theology, creed, apathy, about Pneumatology, illumination, evocation, about Christology, incarnation, and Christ imitation, about Anthropology, person’s freedom, divinization, about Ecclesiology, heart animate worship and about Eschatology, the Fool come from the escheat to renew the present. We also examined the definition of holiness generally and the holiness of the Fools particularly, then we examined the recognition of the saint and especially haw the Church recognized such Holy Fools as saints between its others saints. We conclude finally that in deed those saints had a dogmatic background in their lives.

description: We investigate limitations imposed by sequential attacks on the performance of differential-phase-shift quantum key distribution protocols that use pulsed coherent light. In particular, we analyze two sequential attacks based on unambiguous state discrimination and minimum error discrimination, respectively, of the signal states emitted by the source. Sequential attacks represent a special type of intercept-resend attacks and, therefore, they do not allow the distribution of a secret key.

description: We present Very Large Array 7 mm continuum observations of four Ultra-Compact (UC)HII regions, observed previously at 1.3 cm, in order to investigate the nature of the compact radio sources associated with these regions. We detected a total of seven compact radio sources, four of them with thermal emission, and two compact radio sources have clear non-thermal emission. The thermal emission is consistent with the presence of an ionized envelope, either static (i.e., trapped in the gravitational radius of an associated massive star) or flowing away (i.e., a photo-evaporative flow). On the other hand, the nature of the non-thermal sources remains unclear and several possibilities are proposed. The possibility that most of these compact radio sources are photo-evaporating objects and the remaining ones more-evolved objects is consistent with previous studies on UCHII regions.

description: We reassess the estimate of the cross-correlation of the spatial distribution of the NRAO VLA Sky Survey (NVSS) radio sources with that of Cosmic Microwave Background (CMB) anisotropies from the Wilkinson Microwave Anisotropy Probe (WMAP). This re-analysis is motivated by the fact that most previous studies adopted a redshift distribution of NVSS sources inconsistent with recent data. We find that the constraints on the bias-weighted redshift distribution, b(z)xN(z), of NVSS sources, set by the observed angular correlation function, w(theta), strongly mitigate the effect of the choice of N(z). If such constraints are met, even highly discrepant redshift distributions yield NVSS-WMAP cross-correlation functions consistent with each other within statistical errors. The models favoured by recent data imply a bias factor, b(z), decreasing with increasing z, rather than constant, as assumed by most previous analyses. As a consequence, the function b(z)xN(z) has more weight at z<1, i.e. in the redshift range yielding the maximum contribution to the ISW in a standard LambdaCDM cosmology. On the whole, the NVSS turns out to be better suited for ISW studies than generally believed, even in the absence of an observational determination of the redshift distribution. The NVSS-WMAP cross-correlation function is found to be fully consistent with the prediction of the standard LambdaCDM cosmology.

description: Increasing evidence suggests that dysregulated miRNA expression can lead to the tumorigenesis of osteosarcoma (OS). Nevertheless, the potential role of miR-23b-3p in OS is unclear and remains to be explored. Microarray analysis was performed to identify key genes involved in OS. Reverse transcription quantitative polymerase chain reaction and Western blotting were used to examine miR-23b-3p expression, ventricular zone expressed PH domain-containing 1 (VEPH1) transcript (as well as other transcripts as indicated), and phosphatidylinositol 3-kinase/protein kinase B (PI3K/AKT) signaling pathway-related protein expression. A luciferase reporter gene assay was performed to confirm the regulatory relationship between VEPH1 mRNA and miR-23b-3p. Cell viability was evaluated using the Cell Counting Kit-8 assay, cell growth was assessed using the bromodeoxyuridine enzyme-linked immunosorbent assay, and cell migration was tested using a wound healing assay. We found significant upregulation of miR-23b-3p in OS, which prominently promoted the viability, proliferation, and migration of OS cells. Additionally, VEPH1 was found to be a target of miR-23b-3p and its expression was decreased in OS. Lastly, VEPH1 alleviated the promotion effect of miR-23b-3p on the malignancy phenotypes of OS cells via the PI3K/AKT signaling pathway. Thus, miR-23b-3p augmented the viability, proliferation, and migration of OS cells by directly targeting and downregulating VEPH1, which inhibited the activation of the PI3K/AKT signaling pathway.
The Consistent Result of Cosmological Constant From Quantum Cosmology and Inflation with Born-Infeld Scalar Field

description: The Quantum cosmology with Born-Infeld(B-I) type scalar field is considered. In the extreme limits of small cosmological scale factor the wave function of the universe can also be obtained by applying the methods developed by Hartle-Hawking(H-H) and Vilenkin. H-H wave function predicts that most Probable cosmological constant $Λ$ equals to $\frac{1}η$($\frac{1}{2η}$ equals to the maximum of the kinetic energy of scalar field). It is different from the original results($Λ=0$) in cosmological constant obtained by Hartle-Hawking. The Vilenkin wave function predicts a nucleating unverse with largest possible cosmological constant and it is larger than $1/η$. The conclusions have been nicely to reconcile with cosmic inflation. We investigate the inflation model with B-I type scalar field, and find that $η$ depends on the amplitude of tensor perturbation $δ_h$, with the form $\frac{1}η\simeq \frac{m^2}{12π[(\frac{9δ_Φ^2}{N δ_h^2})^2-1]}.$ The vacuum energy in inflation epoch depends on the tensor-to-scalar ratio $\frac{δ_h}{δ_Φ}$. The amplitude of the tensor perturbation ${δ_{h}}$ can, in principle, be large enough to be discovered. However, it is only on the border of detectability in future experiments. If it has been observed in future, this is very interesting to determine the vacuum energy in inflation epoch.

Connecting planet formation and astrochemistry: C/O and N/O of warm giant planets and Jupiter-analogs

description: (Abridged) The chemical composition of planetary atmospheres has long been thought to store information regarding where and when a planet accretes its material. Predicting this chemical composition theoretically is a crucial step in linking observational studies to the underlying physics that govern planet formation. As a follow-up to a study of hot Jupiters in our previous work, we present a population of warm Jupiters (semi-major axis between 0.5-4 AU) extracted from the same planetesimal formation population synthesis model as used in our previous work. We compute the astrochemical evolution of the protoplanetary disks included in this population to predict the carbon-to-oxygen (C/O) and nitrogen-to-oxygen (N/O) ratio evolution of the disk gas, ice, and refractory sources, the accretion of which greatly impacts the resulting C/O and N/O in the atmosphere of giant planets. We confirm that the main sequence (between accreted solid mass and atmospheric C/O) we found previously is largely reproduced by the presented population of synthetic warm Jupiters. And as a result, the majority of the population fall along the empirically derived mass-metallicity relation when the natal disk has solar or lower metallicity. Planets forming from disks with high metallicity ([Fe/H] $>$ 0.1) result in more scatter in chemical properties which could explain some of the scatter found in the mass-metallicity relation. Combining predicted C/O and N/O ratios shows that Jupiter does not fall among our population of synthetic planets, suggesting that it likely did not form in the inner 5 AU of the solar system before proceeding into a Grand Tack. This result is consistent with recent analysis of the chemical composition of Jupiter's atmosphere which suggests that it accreted most of its heavy element abundance farther than tens of AU away from the Sun.

Neutrino Phenomenology, Dark Energy and Leptogenesis from pseudo-Nambu-Goldstone Bosons

description: We consider a model of dynamical neutrino masses via the see-saw mechanism. Nambu-Goldstone bosons (majorons) arise associated with the formation of the heavy right-handed majorana masses. These bosons then acquire naturally soft masses (become pNGB's) at loop level via the Higgs-Yukawa mass terms. These models, like the original neutrino pNGB quintessence schemes of the 1980's that proceed through the Dirac masses, are natural, have cosmological implications through mass varying neutrinos, long range forces, and provide a soft potential for dark energy. We further argue that these models can explain leptogenesis naturally through the decays of the right-handed neutrinos.

description: Uncertainty lower bounds for parameter estimations associated with a unitary family of mixed-state density matrices are obtained by embedding the space of density matrices in the Hilbert space of square-root density matrices. In the Hilbert-space setup the measure of uncertainty is given by the skew information of the second kind, while the uncertainty lower bound is given by the Wigner-Yanase skew information associated with the conjugate observable. Higher-order corrections to the uncertainty lower bound are determined by higher-order quantum skew moments; expressions for these moments are worked out in closed form.

Redistributing union power to women : the experiences of two women’s committees
Creators: name: Foley, Janice R.
Publisher: name: University of British Columbia
Year: 2009

description: This study examined women’s committees in two public sector unions in British Columbia with predominantly female memberships over a twenty year period. The question addressed was how and under what circumstances the committees could secure gains for women, given a context where women remain at a power disadvantage relative to men. Gains sought were of three types: 1) improvements in contract clauses particularly beneficial to women; 2) increased female participation in union governance; and 3) structural changes conducive to future increases in female participation in union governance. Structures as defmed included both formal structures and other regularized procedures, including processes of communication, decision making and resource distribution. Based on literatures from several disciplines, a power model was developed that guided data collection. Data were collected via archival research and semi-structured interviews, and analyzed qualitatively. The study found that the structures governing how the committees operated were significant factors in committee effectiveness and that the active cooperation of the leadership and/or the membership ensured that structures conducive to committee effectiveness existed. The committees’ major challenge was to align their goals with those of the leadership or the membership in order to generate the level of support that would permit them to achieve their goals. The degree of alignment between committee and membership goals affected to what extent the committee could secure goals not supported by the leadership and was the major variable affecting committee power. However, committee power was not necessarily associated with the level of gains achieved for women because both leadership and membership actions and existing union structures could induce outcomes for women not orchestrated by the committees. As a result of this research, the initial power model was refined and the restrictions on the committees’ and leaderships’ use of power were clarified. The utility of crossing the disciplinary boundaries between organizational theory, industrial relations, and political science to explore how power is exercised in unions was demonstrated. Support for the political model of organizations was generated, suggesting that insights gained from the study of unions might advance organizational theorizing.
Relics of Supersymmetry in Ordinary 1-flavor QCD: Hairpin Diagrams and Scalar-Pseudoscalar Degeneracy

description: The large-$N_c$ orientifold planar equivalence between $\mathcal{N}=1$ SUSY Yang-Mills theory and ordinary 1-flavor QCD suggests that low-energy quark-gluon dynamics in QCD should be constrained by the supersymmetry of the parent theory. One SUSY relic expected from orientifold equivalence is the approximate degeneracy of the scalar and pseudoscalar mesons in 1-flavor QCD. Here we study the role of the $q\bar{q}$ annihilation (hairpin) contributions to the meson correlators. These annihilation terms induce mass shifts of opposite sign in the scalar and pseudoscalar channels, making degeneracy plausible. Calculations of valence and hairpin correlators in quenched lattice QCD are consistent with approximate degeneracy, although the errors on the scalar hairpin are large. We also study the role of $q\bar{q}$ annihilation in the 1- and 2-flavor Nambu-Jona Lasinio model, where annihilation terms arise from the chiral field determinant representing the axial U(1) anomaly. Scalar-pseudoscalar degeneracy for the 1-flavor case reduces to a constraint on the relative size of the anomalous and non-anomalous 4-fermion couplings.

We show that the physics of the Sarma phase is sufficient to understand the recent observations of Zwierlein et al. [Science 311, 492 (2006); Nature 442, 54 (2006)] and indicate how the apparent contradictions between this experiment and the experiment of Partridge et al. [Science 311, 503 (2006)] may be resolved.

description: We summarize recent developments in the field of higher dimensional bosonization made by the authors and collaborators and propose a general formula for the field operator in terms of currents and densities in one dimension using a new ingredient known as a `singular complex number'. Using this formalism, we compute the Green function of the homogeneous electron gas in one spatial dimension with short-range interaction leading to the Luttinger liquid and also with long-range interactions that leads to a Wigner crystal whose momentum distribution computed recently exhibits essential singularities. We generalize the formalism to finite temperature by combining with the author's hydrodynamic approach. The one-particle Green function of this system with essential singularities cannot be easily computed using the traditional approach to bosonization which involves the introduction of momentum cutoffs, hence the more general approach of the present formalism is proposed as a suitable alternative.

description: Although the production of YBa$_{2}$Cu$_{3}$O$_{7-δ}$ (Y123) has been extensively reported, there is still a lack of information on the ideal heat treatment to produce this material in the form of one dimension nanostructures. Thus, by means of the Solution Blow Spinning technique, metals embedded in polymer fibers were prepared. These polymer composite fibers were fired and then investigated by thermogravimetric analysis. The maximum sintering temperatures of heat treatment were chosen in the interval \SI{850}{\celsius}-\SI{925}{\celsius} for one hour under oxygen flux. SEM images allowed us to determine the wire diameter as approximately 350~nm for all samples, as well as to map the evolution of the entangled wire morphology with the sintering temperature. XRD analysis indicated the presence of Y123 and secondary phases in all samples. Ac magnetic susceptibility and dc magnetization measurements demonstrated that the sample sintered at \SI{925}{\celsius}/1h is the one with the highest weak-link critical temperature and the largest diamagnetic response.

description: Studies at high pressures and temperatures are helpful for understanding the physical properties of the solid state, including such classes of materials as, metals, semiconductors, superconductors, or minerals. In particular, the phase behaviour of ABX4 scintillating materials is a challenging problem with many implications for other fields including technological applications and Earth and planetary sciences. A great progress has been done in the last years in the study of the pressure-effects on the structural and electronic properties of these compounds. In particular, the high-pressure structural sequence followed by these compounds seems now to be better understood thanks to recent experimental and theoretical studies. Here, we will review studies on the phase behaviour of different ABX4 scintillating materials. In particular, we will focus on discussing the results obtained by different groups for the scheelite-structured orthotungstates, which have been extensively studied up to 50 GPa. We will also describe different experimental techniques for obtaining reliable data at simultaneously high pressure and high temperature. Drawbacks and advantages of the different techniques are discussed along with recent developments involving synchrotron x-ray diffraction, Raman scattering, and ab initio calculations. Differences and similarities of the phase behaviour of these materials will be discussed, on the light of the Fukunaga and Yamaoka and the Bastide diagrams, aiming to improve the actual understanding of their high-pressure behaviour. Possible technological and geophysical implications of the reviewed results will be also commented.

description: The scope of this work is the study of software project management antipatterns and their effective integration in the course of "IT Project Management" of the The Joint Postgraduate Course on “Informatics and Management” of Aristotle University of Thessaloniki. The technological development and social change affect the business environment and all the people working in them, creating unexpected problems and demands. Projects fail to meet their goals as a result of the above. The integrated education of future managers becomes a dynamic challenge in these new environments, which is achieved by proposing new concepts such as software project management antipatterns. Since poor management is one of the most serious problems that a software project may face, it often causes insuperable obstacles to the development team and thus the project itself. The use of software project management antipatterns, through the SPARSE and Webprotege environment, has the potential to enrich and complete the knowledge of Software Project Managers in order to understand directly and on time problems that arise and solve them in the best possible way.

description: In our daily lives, we rely on the proper functioning of supply networks, from power grids to water transmission systems. A single failure in these critical infrastructures can lead to a complete collapse through a cascading failure mechanism. Counteracting strategies are thus heavily sought after. In this article, we introduce a general framework to analyse the spreading of failures in complex networks and demonstrate that both weak and strong connections can be used to contain damages. We rigorously prove the existence of certain subgraphs, called network isolators, that can completely inhibit any failure spreading, and we show how to create such isolators in synthetic and real-world networks. The addition of selected links can thus prevent large scale outages as demonstrated for power transmission grids.

description: We study the multivariate independence polynomials of graphs and the log-concavity of the coefficients of their univariate restrictions. Let $R_{W_4}$ be the operator defined on simple and undirected graphs which replaces each edge with a caterpillar of size $4$. We prove that all graphs in the image of $R_{W_4}$ are what we call pre-Lorentzian, that is, their multivariate independence polynomial becomes Lorentzian after appropriate manipulations. In particular, as pre-Lorentzian graphs have log-concave (and therefore unimodal) independence sequences, our result makes progress on a conjecture of Alavi, Malde, Schwenk and Erdős which asks if the independence sequence of trees or forests is unimodal.

Oliver Madox-Brown’s the Black Swan and Gabriel Denver : a critical edition
Creators: name: Emond, Elizabeth Suzanne
Publisher: name: University of British Columbia
Year: 2009

description: The text of Oliver Madox—Brown’s only published novel, Gabriel Denver, presents a fascinating textual problem. Madox—Brown, the son of the painter Ford Madox Brown, composed the novel sometime during the winter he turned seventeen, 1871—72. During the following year, the young author was browbeaten by Smith, Elder’s principal reader, William Smith Williams, into making extensive and radical revisions before the work would be published in 1873. In 1874, Madox—Brown died, and in 1876 his brothers—in—law, William Michael Rossetti and Franz Hueffer, published what they said was the original version of Gabriel Denver, a tale they called The Black Swan. Manuscript fragments of each version survive, but they are far from finished copy. The challenge, then, is to assign some meaning to the concept of “final authorial intention” when each of the primary sources is either not intentional, not authorial, or not final. I decided to reproduce the text at two different stages of its history: just before Williams first read the tale, and after it had been revised to his satisfaction. My copy—text for the former was Rossetti’s and Hueffer’s The Black Swan, and for the latter, the 1873 Gabriel Denver. I have emended errata in both, and in The Black Swan have removed what were clearly editorial intrusions on Rossetti’s and Hueffer’s part; all these modifications are recorded either in the textual or in the editorial apparatus. Each edited text is accompanied by an apparatus listing variants in wording with the corresponding MS fragments, and changes in wording within the MSS themselves. The two texts do more than present a bibliographical conundrum. They also highlight the similarities and differences in values between the Pre—Raphaelite circle and mainstream Victorian society. Furthermore, though neither work is by any means a literary masterpiece, The Black Swan has an artistic integrity that is completely undermined by the revisions Williams insisted be made in Gabriel Denver in order to minimize its ardent Romanticism. Together, the two tales dramatically illustrate the constraints under which Victorian writers struggled as they saw their works into print.

description: Adiabatic time evolution of degenerate eigenstates of a quantum system provides a means for controlling electronic states since mixing between degenerate levels generates a matrix Berry phase. In the presence of spin-orbit coupling in n-type semiconductor quantum dots the electron Hamiltonian is invariant under time reversal operation and the many body groundstate may be doubly degenerate. This double degeneracy can generate non-Abelian vector potentials when odd number of electrons are present. We find that the antisymmetry of many electron wavefunction has no effect on the matrix Berry phase. We have derived equations that allow one to investigate the effect of electron correlations by expressing the non-Abelian vector potentials for many electron system in terms of single electron non-Abelian vector potentials.

description: We extend the original cylinder conjecture on point sets in affine three-dimensional space to the more general framework of divisible linear codes over $\mathbb{F}_q$ and their classification. Through a mix of linear programming, combinatorial techniques and computer enumeration, we investigate the structural properties of these codes. In this way, we can prove a reduction theorem for a generalization of the cylinder conjecture, show some instances where it does not hold and prove its validity for small values of $q$. In particular, we correct a flawed proof for the original cylinder conjecture for $q = 5$ and present the first proof for $q = 7$.

Στην προσπάθεια αυτή κάναμε μία αναφορά στην αρχαιολογική έρευνα της περιοχής, καθώς και πιο ειδικά στον χώρο των ταφικών πρακτικών. Επιπλέον εξετάστηκαν όλοι οι θεωρητικοί προβληματισμοί πάνω στο θέμα των ταφών απ’ τους οποίους ξεχωρίσαμε αυτόν που υιοθετήθηκε για τη μελέτη. Στην συνέχεια κρίθηκε απαραίτητο να δοθεί το πλαίσιο μέσα στο οποίο εξετάστηκαν οι ταφές, δηλαδή παρουσιάστηκε η κατάσταση που επικρατούσε στη Μακεδονία καθ’ όλες τις χρονικές περιόδους. Μετά απ’ την αναλυτική εξέταση των ταφών κάναμε μία σύνθεση των δεδομένων κατά περιφέρεια και κατά χρονική περίοδο. Τέλος τα συμπεράσματα της έρευνας αποτελούν και την κατακλείδα της εργασίας.
description: The aim of this thesis was to do a research on the burials of Macedonia during the period of EBA to EIA. In this effort we have also presented the archaeological research of the area and more specifically on the matter of burial rites. Furthermore we examined all the theoretical issues concerning burials and pointed out the one used in this study. It was also necessary to present the context of this research on burials, that is to say the conditions in Macedonia throughout all the time periods. After thorough study of the burials, follows a synthesis of the data per region and per time period. Last but not least the conclusions of this effort are the end of the thesis.

description: Die Auftragsstudie "Tourismus und Stadtentwicklung - Auswirkungen von Airbnb auf deutsche Wohnungsmärkte", in Kooperation mit Airbnb Germany GmbH, analysiert die wachsende Bedeutung der Shared-Housing-Plattform für das touristische Ökosystem und den Wohnungsmarkt in Deutschland. Im Mittelpunkt stehen die Fragen, inwiefern Airbnb zur Wohnraumknappheit und zu steigenden Mietpreisen beiträgt und welche wirtschaftlichen, sozialen und städtebaulichen Auswirkungen sich durch die zunehmende Nutzung der Plattform ergeben. Die Untersuchung analysiert Daten aus den sieben einwohnerstärksten deutschen Städten und kombiniert dabei öffentliche und interne Datenquellen sowie Umfrageergebnisse, um ein umfassendes Bild der Wechselwirkungen zwischen dem Wohnungsmarkt und Airbnb zu zeichnen. Die Ergebnisse liefern wertvolle Einblicke in die tatsächlichen Auswirkungen von Kurzzeitvermietungen und tragen dazu bei, die oft kontrovers diskutierten Effekte differenziert zu bewerten.
Quality of a Quantum Error Correcting Scheme and Memory Error Threshold Estimation

description: The error correcting capabilities of the Calderbank-Shor-Steane [[7,1,3]] quantum code, together with a fault-tolerant syndrome extraction by means of several ancilla states, have been numerically studied. A simple probability expression to characterize the code ability for correcting an encoded qubit has been considered. This probability, as a correction quality criterion, permits the error correction capabilities among different recovery schemes to be compared. The memory error threshold is calculated by means of the best method of those considered.
Periodic Eruptive Variability of the Isolated Pre-Main Sequence Star V347 Aurigae

description: V347 Aurigae is associated with the small dark cloud L1438 and appears to be an isolated pre-main sequence star located at distance $d\approx$200 pc. Multi-epoch, archival photometry reveals periodic brightness variations with amplitude $V\approx2.0$ magnitudes occurring on timescales of $\sim$160 days that have persisted for decades. Regular cadence, optical imaging of the source with the Zwicky Transient Facility shows that a small reflection nebula illuminated by V347 Aur also fluctuates in brightness, at times fading completely. Multi-epoch, Keck/HIRES data suggests the presence of two distinct spectral components: a prominent emission-line dominated spectrum with a heavily veiled continuum correlated with the bright photometric state, and an M-type absorption line spectrum associated with quiescence. All spectra exhibit strong Balmer and He I line emission, consistent with accretion, as well as high velocity emission arising from the forbidden transitions of [O I], [N II], and [S II] that are generally associated with collimated jets and disk winds. There is no evidence in existing high dispersion spectroscopy or high resolution imaging for binarity of V347 Aur. The repeating outburst events are possibly linked to accretion instabilities induced by an undetected companion or a structure within the circumstellar disk that periodically increases the mass accretion rate. V347 Aur is perhaps analogous to an EXor-type variable, though more regularly recurring.

description: We present an introductory discussion of deep-inelastic lepton-proton scattering as a means to probe the substructure of the proton. A resume of QCD is given, emphasizing the running of the coupling constant and the DGLAP evolution equations for the parton densities. The determination of parton distributions is discussed and their importance for predictions of processes at the LHC is emphasized. Going beyond the pure DGLAP regime, we briefly discuss the behaviour of parton densities at low x, and the evidence for non-linear absorptive contributions.

description: The decay of B mesons can be predicted within the Heavy Quark Expansion as the decay of a free bottom quark plus corrections which are suppressed by powers of 1/m$_b$. This contribution to Loops&Legs 2024 describes the calculation of the NNLO QCD corrections to nonleptonic decays of a free bottom quark including charm quark mass effects. In particular it outlines the challenges in connection to the computation of master integrals, the renormalization of the effective operators and the problems which arise from calculating traces with γ$_5$ in d dimensions.
Impact of the calibration of the Halo Mass Function on galaxy cluster number count cosmology

description: The halo mass function (HMF) is a critical element in cosmological analyses of galaxy cluster catalogs. We quantify the impact of uncertainties in HMF parameters on cosmological constraints from cluster catalogs similar to those from Planck, those expected from the Euclid, Roman and Rubin surveys, and from a hypothetical larger future survey. We analyse simulated catalogs in each case, gradually loosening priors on HMF parameters to evaluate the degradation in cosmological constraints. While current uncertainties on HMF parameters do not substantially impact Planck-like surveys, we find that they can significantly degrade the cosmological constraints for a Euclid-like survey. Consequently, the current precision on the HMF will not be sufficient for Euclid (or Roman or Rubin) and possible larger surveys. Future experiments will have to properly account for uncertainties in HMF parameters, and it will be necessary to improve precision of HMF fits to avoid weakening constraints on cosmological parameters.

description: The generalized lambda distribution (GLD) is a flexible four parameter distribution with many practical applications. L-moments of the GLD can be expressed in closed form and are good alternatives for the central moments. The L-moments of the GLD up to an arbitrary order are presented, and a study of L-skewness and L-kurtosis that can be achieved by the GLD is provided. The boundaries of L-skewness and L-kurtosis are derived analytically for the symmetric GLD and calculated numerically for the GLD in general. Additionally, the contours of L-skewness and L-kurtosis are presented as functions of the GLD parameters. It is found that with an exception of the smallest values of L-kurtosis, the GLD covers all possible pairs of L-skewness and L-kurtosis and often there are two or more distributions that share the same L-skewness and the same L-kurtosis. Examples that demonstrate situations where there are four GLD members with the same L-skewness and the same L-kurtosis are presented. The estimation of the GLD parameters is studied in a simulation example where method of L-moments compares favorably to more complicated estimation methods. The results increase the knowledge on the distributions that belong to the GLD family and can be utilized in model selection and estimation.

description: We discuss several new ideas for reactor neutrino oscillation experiments with a Large Liquid Scintillator Detector. We consider two different scenarios for a measurement of the small mixing angle $θ_{13}$ with a mobile $\barν_e$ source: a nuclear-powered ship, such as a submarine or an icebreaker, and a land-based scenario with a mobile reactor. The former setup can achieve a sensitivity to $\sin^2 2θ_{13} \lesssim 0.003$ at the 90% confidence level, while the latter performs only slightly better than Double Chooz. Furthermore, we study the precision that can be achieved for the solar parameters, $\sin^2 2θ_{12}$ and $Δm_{21}^2$, with a mobile reactor and with a conventional power station. With the mobile reactor, a precision slightly better than from current global fit data is possible, while with a power reactor, the accuracy can be reduced to less than 1%. Such a precision is crucial for testing theoretical models, e.g. quark-lepton complementarity.
