description: A significant fraction of planetary nebulae (PNe) and proto-planetary nebulae (PPNe) exhibit aspherical, axisymmetric structures, many of which are highly collimated. The origin of these structures is not entirely understood, however recent evidence suggests that many observed PNe harbor binary systems, which may play a role in their shaping. In an effort to understand how binaries may produce such asymmetries, we study the effect of low-mass (< 0.3 M_sun) companions (planets, brown dwarfs and low-mass main sequence stars) embedded into the envelope of a 3.0 M_sun star during three epochs of its evolution (Red Giant Branch, Asymptotic Giant Branch (AGB), interpulse AGB). We find that common envelope evolution can lead to three qualitatively different consequences: (i) direct ejection of envelope material resulting in a predominately equatorial outflow, (ii) spin-up of the envelope resulting in the possibility of powering an explosive dynamo driven jet and (iii) tidal shredding of the companion into a disc which facilitates a disc driven jet. We study how these features depend on the secondary's mass and discuss observational consequences.

Deriving the Normalized Min-Sum Algorithm from Cooperative Optimization
Creators: name: Huang, Xiaofei
Publisher: name: arXiv
Year: 2006
Subjects: subject: Information Theory (cs.IT)
subject: FOS: Computer and information sciences

description: The normalized min-sum algorithm can achieve near-optimal performance at decoding LDPC codes. However, it is a critical question to understand the mathematical principle underlying the algorithm. Traditionally, people thought that the normalized min-sum algorithm is a good approximation to the sum-product algorithm, the best known algorithm for decoding LDPC codes and Turbo codes. This paper offers an alternative approach to understand the normalized min-sum algorithm. The algorithm is derived directly from cooperative optimization, a newly discovered general method for global/combinatorial optimization. This approach provides us another theoretical basis for the algorithm and offers new insights on its power and limitation. It also gives us a general framework for designing new decoding algorithms.

description: Solar wind stream interaction regions (SIRs) are often characterized by energetic ion enhancements. The mechanisms accelerating these particles, as well as the locations where the acceleration occurs, remain debated. Here, we report the findings of a simulation of a SIR event observed by Parker Solar Probe at ~0.56 au and the Solar Terrestrial Relations Observatory-Ahead at ~0.95 au in 2019 September when both spacecraft were approximately radially aligned with the Sun. The simulation reproduces the solar wind configuration and the energetic particle enhancements observed by both spacecraft. Our results show that the energetic particles are produced at the compression waves associated with the SIR and that the suprathermal tail of the solar wind is a good candidate to provide the seed population for particle acceleration. The simulation confirms that the acceleration process does not require shock waves and can already commence within Earth's orbit, with an energy dependence on the precise location where particles are accelerated. The three-dimensional configuration of the solar wind streams strongly modulates the energetic particle distributions, illustrating the necessity of advanced models to understand these particle events.

description: We study an extension of the gravity dual to a perfect fluid model found by Janik and Peschanski. By relaxing one of the constraints, namely invariance under reflection in the longitudinal direction, we introduce a metric ansatz which includes off-diagonal terms. We also include an $R$-charge following Bak and Janik. We solve the Maxwell-Einstein equations and through holographic renormalization, we show that the off-diagonal components of the bulk metric give rise to heat conduction in the corresponding CFT on the boundary.

Στην έρευνα συμμετείχαν 200 παιδιά και οι νηπιαγωγοί τους από νηπιαγωγεία της Ανατολικής Θεσσαλονίκης. Συμπληρώθηκαν ερωτηματολόγια από τους νηπιαγωγούς για την παιγνιώδη συμπεριφορά των νηπίων. Εφαρμόστηκε ένα κοινωνιομετρικό τεστ για την κατάταξη των νηπίων σε κατηγορίες δημοτικότητας. Στο τέλος, τα παιδιά υποβλήθηκαν σε κινητική δοκιμασία για να εντοπιστεί το επίπεδο της κινητικής δημιουργικότητα τους. Τα αποτελέσματα των αναλύσεων έδειξαν πως διαστάσεις της παιγνιώδους συμπεριφοράς, όπως ο κινητικός και ο κοινωνικός τομέας, επιδρούν θετικά στην ανάπτυξη της κινητικής δημιουργικότητας των νηπίων. Αντίθετα, το κοινωνικό προφίλ φάνηκε ότι επιδρά αρνητικά στην κινητική δημιουργικότητα και συγκεκριμένα, στην καλλιέργεια της φαντασίας των παιδιών προσχολικής ηλικίας. Συμπερασματικά, τα αποτελέσματα της παρούσας έρευνας δίνουν σημαντικές πληροφορίες για τη διαμόρφωση της κινητικής δημιουργικότητας στην προσχολική ηλικία.
description: The present study focused on the investigation of the relationship between playfulness, social profile and motor creativity, i.e, fluency, imagination and originality, in preschoolers. In the study participated 200 children and their preschool teachers from kindergartens in East Thessaloniki. Kindergarten teachers completed the Children’s Playfulness Scale (CPS) for each child separately to assess their playfulness. A sociometric test was used by the researcher to classify children into popularity categories. In addition, children performed a motor test assessing their motor creativity. The results of the analyses indicated that dimensions of playful behavior, such as motor and social sector, positively influence the development of children’s motor creativity. On the other hand, social behavior was found to negatively influence motor creativity, and specifically the dimension of imagination. Overall, the results of the present study provide valuable information about the development of motor creativity in preschoolers.

description: Jump deformations and contractions of Lie algebras are inverse concepts, but the approaches to their computations are quite different. In this paper, we contrast the two approaches, showing how to compute jump deformations from the miniversal deformation of a Lie algebra, and thus arrive at the contractions. We also compute contractions directly. We use the moduli spaces of real 3-dimensional and complex 3 and 4-dimensional Lie algebras as models for explaining a deformation theory approach to computation of contractions.

description: Recent study reported that an aerosolised virus (COVID-19) can survive in the air for a few hours. It is highly possible that people get infected with the disease by breathing and contact with items contaminated by the aerosolised virus. However, the aerosolised virus transmission and trajectories in various meteorological environments remain unclear. This paper has investigated the movement of aerosolised viruses from a high concentration source across a dense urban area. The case study looks at the highly air polluted areas of London: University College Hospital (UCH) and King Cross and St Pancras International Station (KCSPI). We explored the spread and decay of COVID-19 released from the hospital and railway stations with the prescribed meteorological conditions. The study has three key findings: the primary result is that it is possible for the virus to travel from meters up to hundred meters from the source location. The secondary finding shows viruses released into the atmosphere from entry and exit points at KCSPI remain trapped within a small radial distance of < 50m. This strengthens the case for the use of face coverings to reduce the infection rate. The final finding shows that there are different levels of risk at various door locations for UCH, depending on which door is used there can be a higher concentration of COVID-19. Although our results are based on London, since the fundamental knowledge processes are the same, our study can be further extended to other locations (especially the highly air polluted areas) in the world.

description: Ultraviolet-photoemission (UPS) measurements and supporting specific-heat, thermal-expansion, resistivity and magnetic-moment measurements are reported for the magnetic shape-memory alloy Ni$_2$MnGa over the temperature range $100K < T < 250K$. All measurements detect clear signatures of the premartensitic transition ($T_\mathrm{PM}\sim 247K$) and the martensitic transition ($T_\mathrm{M} \sim 196K$). Temperature-dependent UPS shows a dramatic depletion of states (pseudogap) at $T_\mathrm{PM}$ located 0.3eV below the Fermi energy. First-principles electronic structure calculations show that the peak observed at 0.3eV in the UPS spectra for $T > T_\mathrm{PM}$ is due to the Ni-d minority-spin electrons. Below $T_\mathrm{M}$ this peak disappears, resulting in an enhanced density of states at energies around 0.8eV. This enhancement reflects Ni-d and Mn-d electronic contributions to the majority-spin density of states and is accompanied by significant reconstruction of the Fermi surface.

description: The aim of the present thesis was the study and search of alternatives in the management of waste and residues from the olive industry in the area of Messenia. The main steps of the activity are described from olive farming to olive oil production in olive mills and the exploitation of solid residues form second extraction industries for the production of olive stone and olive-kernel oil. The environmental impacts of the oil industry are described and amount and characteristics of the main waste and residues are also being mentioned. Management alternatives are proposed for the exploitation of biomass from olive farming such as olive tree pruning residues, the olive stone use for energy production or heating and the composting of olive tree pruning residues and olive leaves which are produced as waste from olive mills. Special discussion is being made for olive oil mill wastewater and the conventional and alternative treatment methods. Finally, a system for the treatment of olive mills wastewater is being proposed and scenarios of separate and centralized treatment plants are examined on the basis of economic sustainability of olive mills.

description: Illustrations are widely used in education, and sometimes, alternatives are not available for visually impaired students. Therefore, those students would benefit greatly from an automatic illustration description system, but only if those descriptions were complete, correct, and easily understandable using a screenreader. In this paper, we report on a study for the assessment of automated image descriptions. We interviewed experts to establish evaluation criteria, which we then used to create an evaluation questionnaire for sighted non-expert raters, and description templates. We used this questionnaire to evaluate the quality of descriptions which could be generated with a template-based automatic image describer. We present evidence that these templates have the potential to generate useful descriptions, and that the questionnaire identifies problems with description templates.

description: We calculate the CP averaged branching ratios and CP-violating asymmetries for $B^0 \to ηη, ηη^\prime$ and $η^\prime η^\prime$ decays by employing the perturbative QCD (pQCD) factorization approach. The pQCD predictions for the CP-averaged branching ratios are $Br(B^0 \to ηη) \approx 0.67 \times 10^{-7}$, $Br(B^0 \to ηη^\prime) \approx 0.18 \times 10^{-7}$, and $Br(B^0 \to η^{\prime} η^{\prime}) \approx 0.11 \times 10^{-7}$, which are consistent with currently available experimental upper limits. We also predict large CP-violating asymmetries for the considered three decay modes, which can be tested by the future B meson experiments.

description: The concepts of paracontracting, pseudocontracting and nonexpanding operators have been shown to be useful in proving convergence of asynchronous or parallel iteration algorithms. The purpose of this paper is to give characterizations of these operators when they are linear and finite-dimensional. First we show that pseudocontractivity of stochastic matrices with respect to sup-norm is equivalent to the scrambling property, a concept first introduced in the study of inhomogeneous Markov chains. This unifies results obtained independently using different approaches. Secondly, we generalize the concept of pseudocontractivity to set-contractivity which is a useful generalization with respect to the Euclidean norm. In particular, we demonstrate non-Hermitian matrices that are set-contractive for ||.||_2, but not pseudocontractive for ||.||_2 or sup-norm. For constant row sum matrices we characterize set-contractivity using matrix norms and matrix graphs. Furthermore, we prove convergence results in compositions of set-contractive operators and illustrate the differences between set-contractivity in different norms. Finally, we give an application to the global synchronization in coupled map lattices.

description: For each integer n\ge 2, we construct an irreducible, smooth, complex projective variety M of dimension n, whose fundamental group has infinitely generated homology in degree n+1 and whose universal cover is a Stein manifold, homotopy equivalent to an infinite bouquet of n-dimensional spheres. This non-finiteness phenomenon is also reflected in the fact that the homotopy group π_n(M), viewed as a module over Zπ_1(M), is free of infinite rank. As a result, we give a negative answer to a question of Koll'ar on the existence of quasi-projective classifying spaces (up to commensurability) for the fundamental groups of smooth projective varieties. To obtain our examples, we develop a complex analog of a method in geometric group theory due to Bestvina and Brady.

description: We recently proposed a scheme for the creation of coherent superpositions of vortex states in Bose-Einstein condensates (BEC) using orbital angular momentum (OAM) states of light [Phys. Rev. Lett. 95, 173601 (2005)]. Here we discuss further technical details of the proposal, provide alternative, time-reversal-symmetric scheme for transfer of a superposition of OAM states of light to the BEC via a procedure analogous to the traditional STimulated Raman Adiabatic Passage (STIRAP) technique, and discuss an alternative trap configuration conducive for sustaining large charge vortices. Superpositions of OAM states of light, created using experimental techniques, can be transfered to an initially nonrotating BEC via a specially devised Raman coupling scheme. The techniques proposed here open up avenues to study coherent interaction of OAM states of light with matter. The study could also be employed for performing various quantum information processing tasks with OAM states of light--including a memory for a quantum state of the initial superposition.

The impact of endogenous retrovirus-like sequences on the human genome
Creators: name: Goodchild, Nancy L.
Publisher: name: University of British Columbia
Year: 2009

description: Transposable elements comprise ~10% of the human genome and are hypothesized to play a significant role in genome variability and gene regulation. My work has focused on the RTVL-H family of human endogenous retroviruses and the possible impact these elements may have had and continue to have on the human genome. The evolutionary history of the RTVL-H family within the primate lineage was examined using several approaches. My findings suggest that the RTVL-H family has undergone two successive waves of amplification during primate evolution. The major amplification of RTVL-H elements appears to have occurred very early within the Old World primate lineage, after its divergence from the New World monkeys. The genomes of humans, apes and Old World monkeys are estimated to contain 50-100 copies of undeleted elements and 800-1000 copies of deleted sequences. This is in contrast to the New World monkey, marmoset, genome which contains only a handful of intact elements and ~50 deleted sequences. A second expansion of deleted elements appears to have occurred within a common ancestor of the ape lineage and was associated with a novel long terminal repeat (LTR) subtype. The structure of RTVL-H elements and their distribution in the genome suggest that RTVL-H elements amplified via retrotransposition. I have found evidence for this through the identification of an RTVL-H element in the orangutan genome that appears to represent the reverse transcription and integration of a spliced RTVL-H transcript. An apparent spliced genomic element found in human DNA lacks an intact 5’ LTR and may represent a processed RTVL-H pseudogene. This element appears to be polymorphic in the human population. I have also laid the ground work for a strategy to demonstrate RTVL-H retrotransposition within an experimental time frame. This strategy uses a “retro- transposition indicator gene” and allows for the direct selection of a retrotransposition event. RTVL-H LTRs contain transcriptional regulatory sequences and thus may affect the expression of adjacent cellular sequences. I have identified a clone, termed cPj-LTR, containing an ORF of 223 aa that has been polyadenylated within an RTVL-H LTR. The corresponding gene, termed PLT, is a novel, multi-exon locus that appears to have been evolutionarily conserved. Northern analysis identified several PLT-related transcripts in placental RNA samples, one of which appears to be associated with the LTR. The presence of this PLT-LTR fusion transcript was confirmed by PCR. Analysis of additional PLT cDNA clones suggests that the PLT mRNA undergoes alternative splicing at its 3’ end, with polyadenylation within an RTVL-H LTR occurring in one of the resulting transcripts.

description: We report the results of experimental investigations on structural, magnetic, resistivity, caloric properties of Fe$_2$RhZ (Z=Si,Ge) along with \textit{ab-initio} band structure calculations using first principle simulations. Both these alloys are found to crystallize in inverse Heusler structure but with disorder in tetrahedral sites between Fe and Rh. Fe$_2$RhSi has saturation moment of 5.00 $μ_B$ and while its counterpart has 5.19 $μ_B$. Resistivity measurement reveals metallic nature in both of them. Theoretical simulations using generalized gradient approximation(GGA) predict inverse Heusler structure with ferromagnetic ordering as ground state for both the alloys. However it underestimates the experimentally observed moments. GGA+$U$ approach, with Hubbard $U$ values estimated from density functional perturbation theory helps to improve the comparison of the experimental results. Fe$_2$RhSi is found to be half metallic ferromagnet while Fe$_2$RhGe is not. Varying $U$ values on Fe and Rh sites does not change the net moment much in Fe$_2$RhSi, unlike in Fe$_2$RhGe. Relatively small exchange splitting of orbitals in Fe$_2$RhGe compared to that of Fe$_2$RhSi is the reason for not opening the band gap in the minority spin channel in the former. High ordering temperature and moment make Fe$_2$RhSi useful for spintronics applications.

description: We study the symmetries of twisted trilayer graphene's band structure under various extrinsic perturbations, and analyze the role of long-range electron-electron interactions near the first magic angle. The electronic structure is modified by these interactions in a similar way to twisted bilayer graphene. We analyze electron pairing due to long-wavelength charge fluctuations, which are coupled among themselves via the Coulomb interaction and additionally mediated by longitudinal acoustic phonons. We find superconducting phases with either spin singlet/valley triplet or spin triplet/valley singlet symmetry, with critical temperatures of up to a few Kelvin for realistic choices of parameters.

description: The development of epitaxy techniques for localized growth of crystalline silicon nanofilms and nanostructures has been crucial to recent advances in electronics and photonics. A precise definition of the crystal growth location, however, requires elaborate pre-epitaxy processes for substrate patterning. Our molecular dynamics simulations reveal that homoepitaxial silicon nanofilms can be directly deposited by a crystalline silicon tip rubbing against the substrate, thus enabling geometrically controlled crystal growth with no need for substrate pre-patterning. We name this solid-phase epitaxial growth triboepitaxy as it solely relies on shear-induced amorphization and recrystallization that occur even at low temperature at the sliding interface between two silicon crystals. The interplay between the two concomitant, shear-induced processes is responsible for the formation of an amorphous sliding interface with constant nanometric thickness. If the two elastically anisotropic crystals slide along different crystallographic orientations, the amorphous layer can move unidirectionally perpendicular to the sliding plane, causing the crystal with lowest elastic energy per atom to grow at the expenses of the other crystal. As triboepitaxial growth is governed by the shear elastic response of the two crystals along the sliding direction, it can be implemented as a mechanical scanning-probe lithography method in which epitaxial growth is controlled by tuning the crystallographic misorientation between tip and substrate, the tip's size or the normal force. These results suggest a radically new way to conceive nanofabrication techniques that are based on tribologically induced materials transformations.

description: We review some applications of central limit theorems and extreme values statistics in the context of disordered systems. We discuss several problems, in particular concerning Random Matrix Theory and the generalisation of the Tracy-Widom distribution when the disorder has ``fat tails''. We underline the relevance of power-law tails for Directed Polymers and mean-field Spin Glasses, and we point out various open problems and conjectures on these matters. We find that in many instances the assumption of Gaussian disorder cannot be taken for granted.

description: In this paper, we present a fast min-sum algorithm for decoding LDPC codes over GF(q). Our algorithm is different from the one presented by David Declercq and Marc Fossorier in ISIT 05 only at the way of speeding up the horizontal scan in the min-sum algorithm. The Declercq and Fossorier's algorithm speeds up the computation by reducing the number of configurations, while our algorithm uses the dynamic programming instead. Compared with the configuration reduction algorithm, the dynamic programming one is simpler at the design stage because it has less parameters to tune. Furthermore, it does not have the performance degradation problem caused by the configuration reduction because it searches the whole configuration space efficiently through dynamic programming. Both algorithms have the same level of complexity and use simple operations which are suitable for hardware implementations.

description: Η στατιστική και οι επιδόσεις των παικτών και των ομάδων αποτελούν σημαντική πτυχή του αθλητισμού και ειδικότερα της καλαθοσφαίρισης και συνεπώς απασχολούν συχνά τα διοικητικά και προπονητικά επιτελεία των ομάδων. Η στατιστική μέσω των Sports Analytics έχει γίνει αναπόσπαστο κομμάτι στη λήψη αποφάσεων και στη δημιουργία στρατηγικών των ομάδων. Στην παρούσα εργασία θα μας απασχολήσει η αξιοποίηση των στατιστικών δεδομένων των ομάδων του NBA και πιο συγκεκριμένα η κατηγορία στατιστικών εντοπισμού θέσης (tracking stats), μια καινοτόμας κατηγορίας δεδομένων που έκαναν την εμφάνιση τους στο χώρο του επαγγελματικού αθλητισμού τα τελευταία χρόνια. Για το λόγο αυτό δημιουργήσαμε μια web based online εφαρμογή, με δυναμική άντληση των δεδομένων απευθείας από το διαδίκτυο, όπου δίνει στο χρήστη την πρόσβαση σε μια πληθώρα στατιστικών κατηγοριών για τις ομάδες του NBA. Επιπρόσθετα θα του δίνει τη δυνατότητα οπτικοποίησης όλων των δεδομένων σε πολλαπλούς τύπους γραφημάτων με πολλές διαφορετικές επιλογές, τις οποίες ο κάθε χρήστης θα μπορεί να τις προσαρμόσει με βάση τις επιθυμίες του.

Τέλος, θα επιχειρηθεί η εφαρμογή μοντέλων ικανών να περιγράψουν το ποσοστό των νικών και η δημιουργία προβλέψεων.
description: The statistical performance of players and teams are important aspect of sports, especially basketball and therefore often concerns administrative and coaching staffs of the teams. Statistics through Sports Analytics have become inseparable part of decision making and creation of strategic for professional athletic teams. In this thesis we investigate the use of statistical data of the NBA teams, and more specifically the tracking stats, an innovative category of data which have appeared in the field of professional sports in recent years. For this reason we created a web based online application, which gives the user access to a multitude of statistical categories for the NBA teams. Additionally it enables visualization of all data to multiple chart types with lots of different options, that each user can adjust them according to his desire. Afterwards we will describe longitudinal data analysis methods, with particular emphasis on mixed effects models, which we will use in modeling the percentage of wins of the NBA teams. Finally, will be attempted the creation of models capable of describing the win percentage and forecasting.

description: We study Josephson junctions between a multi-band iron-pnictide Ba1-xNaxFe2As2 and conventional s-wave superconductors Nb and Cu/Nb bilayer. We observe that junctions with a Cu interlayer exhibit much larger IcRn, despite a weaker proximity-induced superconductivity. This counterintuitive result is attributed to the difference in Fermi surface geometries of Nb and Cu, which leads to a selective one-band tunneling from Cu and a non-selective multi-band tunnelng from Nb. The latter leads to a mutual cancellation of supercurrents due to the sign-reversal s+- symmetry of the order parameter in the pnictide. Our results indicate that Fermi surface geometries play a crucial role for pnictide-based junctions. This provides a new tool for phase sensitive studies and paves a way to a conscious engineering of such junctions.

Cross-Cultural Perspectives on Personality and Relationship Satisfaction

subject: Clinical psychology

description: The interplay between personality traits and relationship satisfaction across diverse cultural contexts is a pivotal area in cross-cultural psychology, with significant implications for theory and practice. This comprehensive review examines how personality traits, particularly those in the Five-Factor Model (FFM), influence relationship satisfaction in romantic, familial, and parent-child contexts. By integrating Persian and English literature, it synthesizes findings from Iranian studies emphasizing collectivist values and global research highlighting universal and individualist perspectives. Results indicate that conscientiousness and agreeableness are robust predictors of relationship satisfaction in collectivist cultures like Iran, while extraversion is more prominent in individualist societies. Neuroticism consistently shows a negative association across cultures. Cultural dimensions, such as collectivism versus individualism, shape these dynamics, with collectivist societies prioritizing relational harmony and individualist societies valuing personal fulfillment. The review also explores measurement challenges, non-romantic relationships, and clinical applications, identifying gaps like limited Middle Eastern cross-cultural comparisons. It advocates for culturally sensitive models and proposes future research directions, including mixed-methods studies and broader relational contexts, to advance cross-cultural psychology and inform culturally tailored interventions.
