description: We present an analysis of Mg II $\lambda2798$ and Fe II UV emission lines for archival Sloan Digital Sky Survey (SDSS) quasars to explore diagnostics of the magnesium-to-iron abundance ratio in a broad-line region cloud. Our sample consists of 17,432 quasars selected from the SDSS Data Release 7 with a redshift range of $0.72 < z < 1.63$. A strong anticorrelation between Mg II equivalent width (EW) and the Eddington ratio is found, while only a weak positive correlation is found between Fe II EW and the Eddington ratio. To investigate the origin of these differing behaviors of Mg II and Fe II emission lines, we have performed photoionization calculations using the Cloudy code, where constraints from recent reverberation mapping studies are considered. We find from calculations that (i) Mg II and Fe II emission lines are created at different regions in a photoionized cloud, and (ii) their EW correlations with the Eddington ratio can be explained by just changing the cloud gas density. These results indicate that the Mg II/Fe II flux ratio, which has been used as a first-order proxy for the Mg/Fe abundance ratio in chemical evolution studies with quasar emission lines, depends largely on the cloud gas density. By correcting this density dependence, we propose new diagnostics of the Mg/Fe abundance ratio for a broad line region cloud. Comparing the derived Mg/Fe abundance ratios with chemical evolution models, we suggest that $α$-enrichment by mass loss from metal-poor intermediate-mass stars occurred at $z\sim2$ or earlier.

description: We study the orientation dependence of the reconstructed deceleration parameter as a function of redshift. We use the Union 2 and Loss datasets, by using the well known preferred axis discussed in the literature, finding the best fit reconstructed deceleration parameter. We found that a low redshift transition of the reconstructed $q(z)$ is clearly absent in one direction and amazingly sharp in the opposite one. We discuss the possibility that such a behavior can be associated with large scale structures affecting the data.

description: Στην παρούσα διπλωματική εργασία με τίτλο «Ανάλυση Οικονομικών καταστάσεων σε υπό κατασκευή εργοστάσιο φαρμακευτικής κάνναβης στην Ελλάδα» γίνεται αναφορά στην ένταξή της φαρμακευτικής κάνναβης στην αγορά της χώρας μας. Τα τελευταία χρόνια, το δημόσιο ενδιαφέρον παγκοσμίως έχει στραφεί προς τις θεραπευτικές ιδιότητες της κάνναβης, οδηγώντας σε αύξηση της φαρμακευτικής της χρήσης. Η χρήση της κάνναβης έχει ρυθμιστεί εδώ και καιρό με νόμο λόγω των ψυχοδραστικών της επιδράσεων και της πιθανότητας κατάχρησης. Το ισχύον νομικό πλαίσιο για τη ρύθμιση της κάνναβης για ιατρικούς σκοπούς στην Ευρωπαϊκή Ένωση και τις Ηνωμένες Πολιτείες της Αμερικής διερευνάται υπό το φως των συμβάσεων των Ηνωμένων Εθνών και της διάφορης εθνικής και κρατικής νομοθεσίας για την παραγωγή, το εμπόριο και τη χρήση. Έχουν γίνει επίσης προσπάθειες να διερευνηθεί ο οικονομικός και κοινωνικός αντίκτυπος της χρήσης φαρμακευτικής κάνναβης στη δημόσια υγεία και την κοινωνία από την «απελευθέρωση» της καλλιέργειας, παραγωγής και χρήσης της, για παράδειγμα οι Ηνωμένες Πολιτείες της Αμερικής και ο Καναδάς έχουν εφαρμόσει νόμους για «απελευθερώστε» την κάνναβη τόσο για ιατρικούς όσο και για «ψυχαγωγικούς» σκοπούς. Αναμφίβολα, το αυξημένο ενδιαφέρον των καταναλωτών για τη συνολική υγεία και ευεξία στον απόηχο της πανδημίας θα συνεχίσει να τροφοδοτεί την ταχεία ανάπτυξη της βιομηχανίας φαρμακευτικής κάνναβης. Η παρούσα εργασία γράφτηκε στο πλαίσιο της χρήσης μελετών δυναμικής συστημάτων και του σχεδιασμού προγράμματος ελέγχου παραγωγής (PCP) με στόχο την ανάπτυξη κατάλληλου μοντέλου για την αποτελεσματική προσομοίωση της παραγωγής φαρμακευτικής κάνναβης στην Ελλάδα. Η παραγωγή φαρμακευτικής κάνναβης στην Ελλάδα διέπεται από το Ν. 4523/2018 «Ρυθμίσεις Παραγωγής Έτοιμης Κάνναβης Φαρμακευτικής Χρήσης και Άλλοι Κανονισμοί» (Α' 41), ο οποίος προστέθηκε στον Νόμο για τις Εθιστικές Ουσίες (Α) 4139/2013.

description: Realistic propagation modeling requires a detailed understanding and characterization of the radio channel properties. This paper is based on channel sounder measurements with 1 GHz bandwidth at a carrier frequency of 5.7 GHz and particular tracking methods. We present statistical models for the number of, birth rate, lifetime, excess delay and relative Doppler frequency of individual multipath components (MPCs). Our findings are concluded from 72 measurement runs in eight relevant vehicular communication scenarios and reveal wide insights into the dynamic propagation process in vehicular communication scenarios.

description: Conventional LIDAR systems require hundreds or thousands of photon detections to form accurate depth and reflectivity images. Recent photon-efficient computational imaging methods are remarkably effective with only 1.0 to 3.0 detected photons per pixel, but they are not demonstrated at signal-to-background ratio (SBR) below 1.0 because their imaging accuracies degrade significantly in the presence of high background noise. We introduce a new approach to depth and reflectivity estimation that focuses on unmixing contributions from signal and noise sources. At each pixel in an image, short-duration range gates are adaptively determined and applied to remove detections likely to be due to noise. For pixels with too few detections to perform this censoring accurately, we borrow data from neighboring pixels to improve depth estimates, where the neighborhood formation is also adaptive to scene content. Algorithm performance is demonstrated on experimental data at varying levels of noise. Results show improved performance of both reflectivity and depth estimates over state-of-the-art methods, especially at low signal-to-background ratios. In particular, accurate imaging is demonstrated with SBR as low as 0.04. This validation of a photon-efficient, noise-tolerant method demonstrates the viability of rapid, long-range, and low-power LIDAR imaging.

description: A proper vertex coloring of a graph $G$ is equitable if the sizes of color classes differ by at most one. The equitable chromatic threshold $χ_{eq}^*(G)$ of $G$ is the smallest integer $m$ such that $G$ is equitably $n$-colorable for all $n\ge m$. We show that for planar graphs $G$ with minimum degree at least two, $χ_{eq}^*(G)\le 4$ if the girth of $G$ is at least $10$, and $χ_{eq}^*(G)\le 3$ if the girth of $G$ is at least $14$.

description: The project “The reconfiguration of the European Union presence in Latin America and the Caribbean” (EUinLAC) was conceived and launched between 2019 and 2020. The European Union Jean Monnet programme generously financed it in 2020 and the project activities were carried out between 2020 and 2023. The project was designed to promote both research and teaching on European Union (EU)-Latin America and the Caribbean (LAC) relations. The first mission was accomplished with the publication of the volume named after the project “The Redefinition of EU presence in Latin America and the Caribbean”, which brings together 18 original contributions on the topic and was published by Peter Lang in 2023. The second objective was met by the release of this innovative open educational resource, or teaching tool, an undertaking that Friedrich-Alexander University Press enthusiastically embraced and published in full open access to reach as wide an audience as possible.

description: A detailed understanding of the dynamic processes of vehicular radio channels is crucial for its realistic modeling. In this paper, we present multipath components (MPCs) tracking results from a channel sounder measurement with 1 GHz bandwidth at a carrier frequency of 5.7 GHz. We describe in detail the applied algorithms and perform a tracking performance evaluation based on artificial channels and on measurement data from a tunnel scenario. The tracking performance of the proposed algorithm is comparable to the tracking performance of the state-of-the-art Gaussian mixture probability hypothesis density filter, yet with a significantly lower complexity. The fluctuation of the measured channel gain is followed very well by the proposed tracking algorithm, with a power loss of only 2.5 dB. We present statistical distributions for the number of MPCs and the birth/death rate. The applied algorithms and tracking results can be used to enhance the development of geometry-based channel models.

description: An exploding primordial black-hole (PBH) may produce a single pulse of electromagnetic radiation detectable at the low-frequency end of the radio spectrum. Furthermore, a radio transient from an exploding PBH could be a signature of an extra spatial dimension. We describe here an approach for searching for PBH explosions using a low-frequency radio antenna array, and as a practical example, the results of a such a search using the Eight-meter-wavelength Transient Array (ETA). No compelling astrophysical signal was detected in $\approx 4$ hours of data implying an observational upper limit on the rate of exploding PBHs is $4.2 \times 10^{-7} \,\rm{pc}^{-3}\,\rm{yr}^{-1}$ for an exploding PBH with a fireball Lorentz factor of $10^{4.5}$ for the standard scenario of Page and Hawking. This rate limit is the strongest constraint yet set for PBH explosions with this fireball Lorentz factor. Observations ($\sim300$ hours) using the Arecibo Observatory were used to set a stronger constraint on the rate of PBH explosions for a fireball Lorentz factor of $10^{4.6}$ but the limit set by those observations for the fireball Lorentz factor considered here are less stringent by more than an order of magnitude. The limits considered here are applicable to exploding PBHs in the halo of the Galaxy. These observations also imply an upper limit of $2.0 \times 10^{-4} \,\rm{pc}^{-3}\,\rm{yr}^{-1}$ on the rate of PBH explosions in the context of certain extra dimension models as described by Kavic et al. This rate limit is for a fireball Lorentz factor of $10^{4.3}$ which corresponds to an extra dimension compactification scale of $3.0 \times 10^{-18}$m.

description: The discovery of illisimonin A in 2017 extended the structural repertoire of the Illicium sesquiterpenoids─a class of natural products known for their high oxidation levels and neurotrophic properties─with a new carbon backbone combining the strained trans-pentalene and norbornane substructures. We report an asymmetric total synthesis of (−)-illisimonin A that traces its tricyclic carbon framework back to a spirocyclic precursor, generated by a tandem-Nazarov/ene cyclization. As crucial link between the spirocyclic key intermediate and illisimonin A, a novel approach for the synthesis of tricyclo[5.2.1.01,5]decanes via radical cyclization was explored. This approach was applied in a two-stage strategy consisting of Ti(III)-mediated cyclization and semipinacol rearrangement to access the natural product’s carbon backbone. These key steps were combined with carefully orchestrated C–H oxidations to establish the dense oxidation pattern.

description: One of the most important questions in game theory concerns how mutual cooperation can be achieved and maintained in a social dilemma. In Axelrod's tournaments of the iterated prisoner's dilemma, Tit-for-Tat (TFT) demonstrated the role of reciprocity in the emergence of cooperation. However, the stability of TFT does not hold in the presence of implementation error, and a TFT population is prone to neutral drift to unconditional cooperation, which eventually invites defectors. We argue that a combination of TFT and anti-TFT (ATFT) overcomes these difficulties in a noisy environment, provided that ATFT is defined as choosing the opposite to the opponent's last move. According to this TFT-ATFT strategy, a player normally uses TFT; turns to ATFT upon recognizing his or her own error; returns to TFT either when mutual cooperation is recovered or when the opponent unilaterally defects twice in a row. The proposed strategy provides simple and deterministic behavioral rules for correcting implementation error in a way that cannot be exploited by the opponent, and suppresses the neutral drift to unconditional cooperation.

These data sets may be distributed geographically, rich in size and as well as dimensions also. To analyze these data sets to find out the hidden patterns, it is required to down- load the data to a centralized site which is a challenging task in terms of the limited bandwidth available and computationally also expensive. The covariance matrix is one of the methods to estimate the relation between any two dimensions. In this paper, we propose a communication efficient algorithm to estimate the covariance matrix in a distributed manner. The global covariance matrix is computed by merging the local covariance matrices using a distributed approach. The results show that it is exactly same as centralized method with good speed-up in terms of computation. The reason for speed-up is because of the parallel construction of local covariances and distributing the cross-covariances among the nodes so that the load is balanced. The results are analyzed by considering Mfeat data set on the various partitions which address the scalability also.

description: The air in the Lombardy region, Italy, is one of the most polluted in Europe because of limited air circulation and high emission levels. There is a large scientific consensus that the agricultural sector has a significant impact on air quality. To support studies quantifying the role of the agricultural and livestock sectors on the Lombardy air quality, this paper presents a harmonised dataset containing daily values of air quality, weather, emissions, livestock, and land and soil use in the years 2016–2021, for the Lombardy region. The daily scale is obtained by averaging hourly data and interpolating other variables. In fact, the pollutant data come from the European Environmental Agency and the Lombardy Regional Environment Protection Agency, weather and emissions data from the European Copernicus programme, livestock data from the Italian zootechnical registry, and land and soil use data from the CORINE Land Cover project. The resulting dataset is designed to be used as is by those using air quality data for research.

description: We provide a gravitational argument in favour of the covariant holographic entanglement entropy proposal. In general time-dependent states, the proposal asserts that the entanglement entropy of a region in the boundary field theory is given by a quarter of the area of a bulk extremal surface in Planck units. The main element of our discussion is an implementation of an appropriate Schwinger-Keldysh contour to obtain the reduced density matrix (and its powers) of a given region, as is relevant for the replica construction. We map this contour into the bulk gravitational theory, and argue that the saddle point solutions of these replica geometries lead to a consistent prescription for computing the field theory Renyi entropies. In the limiting case where the replica index is taken to unity, a local analysis suffices to show that these saddles lead to the extremal surfaces of interest. We also comment on various properties of holographic entanglement that follow from this construction.

description: In the contemporary science and higher education system, national and supranational governments fund and foster universities to collaborate through specific funding lines and competition in World University Rankings, making it indispensable for universities to demonstrate collaboration at the organizational level. Thus, universities strive to encourage their scientific members to collaborate – and to different degrees – facilitate forms of collaboration. Questions on how universities as organizations influence academic research collaboration arise. To go beyond the existing literature, this study firstly develops an analytical two-dimensional framework organizing the literature on four levels of investigation (meta, macro, meso, micro). Based on this framework, the paper presents a literature review of the current state of the art in academic research collaboration. Secondly, the paper establishes a research agenda by synthesizing organizational influences found as organizational characteristics, management strategies, and organizational culture and presents three research avenues for future research. The paper concludes that we have only just begun to study the organizational influences of universities (especially the organizational culture) on academic research collaboration and how these organizational categories are interrelated.

description: This systematic review and meta-analysis aims to synthesise the evidence of the effectiveness of self-management interventions with action-taking components in improving self-efficacy, health-related quality of life, basic and instrumental activities of daily living, and depression for adult stroke survivors. Nine electronic databases were searched for relevant studies, including grey literature and ongoing studies. Randomised controlled trials targeting adult stroke survivors comparing health-related outcomes of patients receiving self-management interventions with action-taking components to usual care, placebo, or no-treatment were included. Screening, data extraction, and methodological quality assessment were conducted by two reviewers. Meta-analyses were performed. Overall quality of evidence was assessed using the GRADE tool. A total of seventeen studies were included. Meta-analyses showed that the intervention may result in a slight increase in self-efficacy (SMD = 0.29, 95% CI [0.07–0.52], p = 0.010, I2 = 47%) and basic activities of daily living (SMD = 0.31, 95% CI [0.16–0.46], p < 0.001, I2 = 0%), but not for the other outcomes. Self-management interventions with action-taking components may result in a slight improvement in self-efficacy and rehabilitation of basic activities of daily living. Future research should investigate which core self-management skill, or combination of them, is most effective in improving short-term and long-term outcomes.IMPLICATIONS FOR REHABILITATIONStroke can be a chronic condition as approximately half of stroke survivors suffer from permanent disabilities.Self-management interventions are one form of rehabilitation programmes available to stroke survivors.Self-management interventions with action-taking components may result in a slight increase in patient self-efficacy and carrying out basic activities of daily living compared to usual care given.

description: The four-body contribution of the model-independent radiative corrections to the Dalitz plot of the semileptonic decays of neutral kaons are computed to order (α/π)(q/M_1), where q is the momentum transfer and M_1 is the kaon mass. The final result is presented in two forms. The first one is given in terms of the triple integration of the bremsstrahlung photon ready to be performed numerically; the second one is a fully analytical expression. This paper is organized to make it accessible and reliable in the analysis of the Dalitz plot of precision experiments involving kaons and is not compromised to fixing the form factors at predetermined values. As a byproduct, gathering together three- and four-body contributions of radiative corrections yields, through a least-squares fit to the measured kaon decay rates, the value f_+^{K^0π^-}|V_{us}| = 0.2168(3).

description: Triterpenoids possess potent biological activities, but their polycyclic skeletons are challenging to synthesize. The skeletal diversity of triterpenoids in plants is generated by oxidosqualene cyclases based on epoxide-triggered cationic rearrangement cascades. Normally, triterpenoid skeletons then remain unaltered during subsequent tailoring steps. In contrast, the highly modified triterpenoids found in Sapindales plants imply the existence of post-cyclization skeletal rearrangement enzymes that have not yet been found. We report here a biosynthetic pathway in Sapindales plants for the modification of already cyclized tirucallane triterpenoids, controlling the pathway bifurcation between different plant triterpenoid classes. Using a combination of bioinformatics, heterologous expression in plants and chemical analyses, we identified a cytochrome P450 monooxygenase and two isomerases which harness the epoxidation-rearrangement biosynthetic logic of triterpene cyclizations for modifying the tirucallane scaffold. The two isomerases share the same epoxide substrate made by the cytochrome P450 monooxygenase CYP88A154, but generate two different rearrangement products, one containing a cyclopropane ring. Our findings reveal a process for skeletal rearrangements of triterpenoids in nature that expands their scaffold diversity after the initial cyclization. In addition, the enzymes described here are crucial for the biotechnological production of limonoid, quassinoid, apoprotolimonoid, and glabretane triterpenoids.
