description: Low-quality and misleading information online can hijack people’s attention, often by evoking curiosity, outrage or anger. Resisting certain types of information and actors online requires people to adopt new mental habits that help them avoid being tempted by attention-grabbing and potentially harmful content. We argue that digital information literacy must include the competence of “critical ignoring”—choosing what to ignore and where to invest one’s limited attentional capacities. We review three types of cognitive strategies for implementing critical ignoring: self-nudging, in which people ignore temptations by removing them from their digital environments; lateral reading, which requires users to vet information by leaving the source and verifying its credibility elsewhere online; and the “do not feed the trolls” heuristic, which advises people to not reward malicious actors with attention. We argue that these strategies implementing critical ignoring should be part of school curricula on digital information literacy. Teaching the competence of critical ignoring requires a paradigm shift in educators’ thinking, from a sole focus on the power and promise of paying close attention to an additional emphasis on the power of ignoring. Encouraging students and other online users to embrace critical ignoring can empower them to shield themselves from the excesses, traps, and information disorders of today’s attention economy.

description: We analyze the trajectories of three geostationary satellites forming the GEOstationary GRAvitational Wave Interferometer (GEOGRAWI)~\cite{tinto}, a space-based laser interferometer mission aiming to detect and study gravitational radiation in the ($10^{-4} - 10$) Hz band. The combined effects of the gravity fields of the Earth, the Sun and the Moon make the three satellites deviate from their nominally stationary, equatorial and equilateral configuration. Since changes in the satellites relative distances and orientations could negatively affect the precision of the laser heterodyne measurements, we have derived the time-dependence of the inter-satellite distances and velocities, the variations of the polar angles made by the constellation's three arms with respect to a chosen reference frame, and the time changes of the triangle's enclosed angles. We find that, during the time between two consecutive station-keeping maneuvers (about two weeks), the relative variations of the inter-satellite distances do not exceed a value of $0.05$ percent, while the relative velocities between pairs of satellites remain smaller than about $0.7 \ {\rm m/s}$. In addition, we find the angles made by the arms of the triangle with the equatorial plane to be periodic functions of time whose amplitudes grow linearly with time; the maximum variations experienced by these angles as well as by those within the triangle remain smaller than $3$ arc-minutes, while the East-West angular variations of the three arms remain smaller than about $15$ arc-minutes during the two-weeks period. The relatively small variations of these orbit parameters result into a set of system functional and performance requirements that are less stringent than those characterizing an interplanetary mission.

description: Water-ice-poor, 5-$μ$m-bright material on Saturn's moon Titan has previously been geomorphologically identified as evaporitic. Here we present a global distribution of the occurrences of the 5-$μ$m-bright spectral unit, identified with Cassini's Visual Infrared Mapping Spectrometer (VIMS) and examined with RADAR when possible. We explore the possibility that each of these occurrences are evaporite deposits. The 5-$μ$m-bright material covers 1\% of Titan's surface and is not limited to the poles (the only regions with extensive, long-lived surface liquid). We find the greatest areal concentration to be in the equatorial basins Tui Regio and Hotei Regio. Our interpretations, based on the correlation between 5-$μ$m-bright material and lakebeds, imply that there was enough liquid present at some time to create the observed 5-$μ$m-bright material. We address the climate implications surrounding a lack of evaporitic material at the south polar basins: if the south pole basins were filled at some point in the past, then where is the evaporite?

Pumping Lemmata for Recognizable Weighted Languages over Artinian Semirings

description: Pumping lemmata are the main tool to prove that a certain language does not belong to a class of languages like the recognizable languages or the context-free languages. Essentially two pumping lemmata exist for the recognizable weighted languages: the classical one for the Boolean semiring (i.e., the unweighted case), which can be generalized to zero-sum free semirings, and the one for fields. A joint generalization of these two pumping lemmata is provided that applies to all Artinian semirings, over which all finitely generated semimodules have a finite bound on the length of chains of strictly increasing subsemimodules. Since Artinian rings are exactly those that satisfy the Descending Chain Condition, the Artinian semirings include all fields and naturally also all finite semirings (like the Boolean semiring). The new pumping lemma thus covers most previously known pumping lemmata for recognizable weighted languages.

description: Αντικείμενο της παρούσας διατριβής είναι η συστηματική καταγραφή της αθλητικής ιστορίας της Καβάλας από το 1906, όταν ιδρύθηκε ο πρώτος γυμναστικός σύλλογος μέχρι το 1970. Μελετάται η λειτουργία των αθλητικών συλλόγων και η αθλητική και κοινωνική δράση τους. Η έρευνα βασίστηκε στα καταστατικά και το αρχειακό υλικό των συλλόγων της πόλης, στο αρχειακό υλικό κρατικών οργανισμών και στις εφημερίδες και περιοδικά που έχουν διασωθεί μέχρι σήμερα. Η επεξεργασία των στοιχείων έδειξε ότι η αθλητική δράση των κατοίκων της Καβάλας ήταν αξιόλογη και πρωτοποριακή για τα δεδομένα της επαρχίας της εποχής εκείνης. Ο πρώτος σύλλογος, «Οι Φίλιπποι», που ιδρύθηκε το 1906 έδωσε το «εναρκτήριο λάκτισμα» στην πόλη για να δραστηριοποιηθεί στο χώρο του αθλητισμού. Στο μεταξύ, σταδιακά, άρχισαν να κάνουν την εμφάνισή τους και άλλοι σύλλογοι με αποτέλεσμα η αθλητική ζωή στην πόλη να γίνεται έντονη. Κυρίαρχη αθλητική δραστηριότητα ήταν το ποδόσφαιρο, στη διάδοση του οποίου συντέλεσε αποφασιστικά η πληθυσμιακή αλλαγή με την έλευση των προσφύγων από τη Μ. Ασία (1922). Η περίοδος 1926-1934 υπήρξε η πιο λαμπρή για τον αθλητισμό της Καβάλας. Παράλληλα το αθλητικό σωματείο αποτελούσε ένα τόπο ψυχαγωγίας και κοινωνικής συνάθροισης. Οι επιρροές από τη Δύση ήταν ολοφάνερες. Οι ξένοι αντιπρόσωποι των καπνεμπορικών οίκων έφερναν μαζί τους συνήθειες που αφομοιώνονταν από τους ντόπιους: ίδρυση Λέσχης, χοροεσπερίδες, συναντήσεις για τένις κ.ά. Τη μεταπολεμική περίοδο η Καβάλα προσπάθησε να ορθοποδήσει και να ξανακερδίσει τη χαμένη της αίγλη στον αθλητικό τομέα. Με μεγάλη δυσκολία αλλά και με εξαιρετικό ζήλο οργανώθηκαν τα πρώτα διοικητικά συμβούλια των συλλόγων με μεγάλες ελλείψεις σε άψυχο αλλά κυρίως σε έμψυχο υλικό. Η δράση των αθλητικών σωματείων ακολούθησε τους ρυθμούς γενικότερα της ανάπτυξης της πόλης που εκ των πραγμάτων ήταν αργοί, εξαιτίας του πολέμου που προηγήθηκε.

colorectal surgery

description: To evaluate the compliance of anesthesia providers in using GDFT following an educational training module. Secondary outcomes included length of hospital stay and rate of surgical site infection. Methods: A retrospective chart review was conducted at a single-site acute care hospital. The sample included colorectal surgery cases between December 2021 and May 2022. The final sample size was 20 patients. Descriptive, comparative, and correlational analysis was performed. Results: There was a lack of provider compliance using GDFT. A significant association exists between fluid volume administered and bleeding requiring intraoperative blood transfusion (p = .018). No relationship was found between fluid volume administered and other complications. In particular, the rate of SSI was not associated with GDFT or ZBFT. Post hoc analysis also revealed a significant association between blood product administration and postoperative kidney complications (p = .013). The ASA Classification was found to positively correlate with the length of hospital stay (p = .002). A significant difference exists in the length of stay across four different ASA Classification levels (p = .017). Conclusions: This study found a significant association between fluid volume and bleeding requiring blood transfusion. Anesthesia providers must consider the risks associated with excess crystalloid administration when providing anesthesia to colorectal surgery patients. In particular, anesthesia providers should consider the significant relationship between blood product administration and kidney complications. Additionally, higher ASA Classifications should alert the anesthesia provider to the possibility of prolonged hospitalization in colorectal surgery patients. Future studies can be conducted with a larger sample size to assess associations between fluid administration and SSI, as SSI remains a leading cause of morbidity in colorectal surgery.

description: One of the tasks of the Kepler Asteroseismic Science Operations Center (KASOC) is to provide asteroseismic analyses on Kepler Objects of Interest (KOIs). However, asteroseismic analysis of planetary host stars presents some unique complications with respect to data preprocessing, compared to pure asteroseismic targets. If not accounted for, the presence of planetary transits in the photometric time series often greatly complicates or even hinders these asteroseismic analyses. This drives the need for specialised methods of preprocessing data to make them suitable for asteroseismic analysis. In this paper we present the KASOC Filter, which is used to automatically prepare data from the Kepler/K2 mission for asteroseismic analyses of solar-like planet host stars. The methods are very effective at removing unwanted signals of both instrumental and planetary origins and produce significantly cleaner photometric time series than the original data. The methods are automated and can therefore easily be applied to a large number of stars. The application of the filter is not restricted to planetary hosts, but can be applied to any solar-like or red giant stars observed by Kepler/K2.

State-deterministic Finite Automata with Translucent Letters and Finite Automata with Nondeterministically Translucent Letters

description: Deterministic and nondeterministic finite automata with translucent letters were introduced by Nagy and Otto more than a decade ago as Cooperative Distributed systems of a kind of stateless restarting automata with window size one. These finite state machines have a surprisingly large expressive power: all commutative semi-linear languages and all rational trace languages can be accepted by them including various not context-free languages. While the nondeterministic variant defines a language class with nice closure properties, the deterministic variant is weaker, however it contains all regular languages, some non-regular context-free languages, as the Dyck language, and also some languages that are not even context-free. In all those models for each state, the letters of the alphabet could be in one of the following categories: the automaton cannot see the letter (it is translucent), there is a transition defined on the letter (maybe more than one transitions in nondeterministic case) or none of the above categories (the automaton gets stuck by seeing this letter at the given state and this computation is not accepting). State-deterministic automata are recent models, where the next state of the computation determined by the structure of the automata and it is independent of the processed letters. In this paper our aim is twofold, on the one hand, we investigate state-deterministic finite automata with translucent letters. These automata are specially restricted deterministic finite automata with translucent letters. In the other novel model we present, it is allowed that for a state the set of translucent letters and the set of letters for which transition is defined are not disjoint. One can interpret this fact that the automaton has a nondeterministic choice for each occurrence of such letters to see them (and then erase and make the transition) or not to see that occurrence at that time. Based on these semi-translucent letters, the expressive power of the automata increases, i.e., in this way a proper generalization of the previous models is obtained.

description: Light nuclei at room temperature and below exhibit a kinetic energy which significantly deviates from the predictions of classical statistical mechanics. This quantum kinetic energy is responsible for a wide variety of isotope effects of interest in fields ranging from chemistry to climatology. It also furnishes the second moment of the nuclear momentum distribution, which contains subtle information about the chemical environment and has recently become accessible to deep inelastic neutron scattering experiments. Here we show how, by combining imaginary time path integral dynamics with a carefully designed generalized Langevin equation, it is possible to dramatically reduce the expense of computing the quantum kinetic energy. We also introduce a transient anisotropic Gaussian approximation to the nuclear momentum distribution which can be calculated with negligible additional effort. As an example, we evaluate the structural properties, the quantum kinetic energy, and the nuclear momentum distribution for a first-principles simulation of liquid water.

description: We identify the graph data structure, frontiers, operators, an iterative loop structure, and convergence conditions as essential components of graph analytics systems based on the native-graph approach. Using these essential components, we propose an abstraction that captures all the significant programming models within graph analytics, such as bulk-synchronous, asynchronous, shared-memory, message-passing, and push vs. pull traversals. Finally, we demonstrate the power of our abstraction with an elegant modern C++ implementation of single-source shortest path and its required components.

description: We investigate the equational theory of Kleene algebra terms with variable complements -- (language) complement where it applies only to variables -- w.r.t. languages. While the equational theory w.r.t. languages coincides with the language equivalence (under the standard language valuation) for Kleene algebra terms, this coincidence is broken if we extend the terms with complements. In this paper, we prove the decidability of some fragments of the equational theory: the universality problem is coNP-complete, and the inequational theory t <= s is coNP-complete when t does not contain Kleene-star. To this end, we introduce words-to-letters valuations; they are sufficient valuations for the equational theory and ease us in investigating the equational theory w.r.t. languages. Additionally, we prove that for words with variable complements, the equational theory coincides with the word equivalence.

description: Ο Σκοπός της έρευνας ήταν η καταγραφή και αξιολόγηση της ποιότητας των υπηρεσιών που παρέχουν τα ιδιωτικά γυμναστήρια της Ηλείας. Για την διερεύνηση της ποιότητας υπηρεσιών χρησιμοποιήθηκε η κλίμακα ποιότητας υπηρεσιών του Alexandris (2002). Το δείγμα αποτέλεσαν 217 πελάτες έξι ιδιωτικών γυμναστηρίων της Ηλείας. Η παραγοντική ανάλυση επιβεβαίωσε σε μεγάλο βαθμό την εγκυρότητα της κλίμακας του Alexandris (2002), καθώς προέκυψαν 7 παράγοντες: Αξιοπιστία, εγκαταστάσεις και τα προγράμματα, γυμναστές, αποτελέσματα στην υγεία, προσωπικό, εξυπηρέτηση, αποτελέσματα στην κοινωνικότητά. Από τις απαντήσεις των πελατών στις επταβάθμιες κλίμακες προέκυψε ότι οι αντιλήψεις τους για όλες τις διαστάσεις της ποιότητας υπηρεσιών ήταν πολύ θετικές με σκορ 6.58 για την αξιοπιστία του γυμναστηρίου, 6.04 για τις εγκαταστάσεις και τα προγράμματα, 6.40 για τους γυμναστές, 6.69 για τα αποτελέσματα στην υγεία τους, 6.54 για το προσωπικό, 6.42 για την εξυπηρέτηση, και 6.39 για τα αποτελέσματα στην κοινωνικότητά τους. Από τις αναλύσεις διακύμανσης προέκυψε στατιστικά σημαντική επίδραση της τοποθεσίας του γυμναστηρίου στις εγκαταστάσεις και τα προγράμματα, στους παράγοντες που αναφέρονται στην αξιοπιστία του γυμναστηρίου και στην εξυπηρέτηση των πελατών, καθώς και στατιστικά σημαντική επίδραση του φύλου των πελατών στους παράγοντες που περιγράφουν το προσωπικό και τους γυμναστές. Οι απόψεις των πελατών για την ποιότητα υπηρεσιών των γυμναστηρίων στην Ηλεία είναι θετικές. Διαφαίνεται ότι τα γυμναστήρια που δραστηριοποιούνται σε αστικές περιοχές είναι περισσότερο ακριβή, αξιόπιστα, και εξυπηρετούν τους πελάτες τους σε μεγαλύτερο βαθμό σε σχέση με τα γυμναστήρια αγροτικών περιοχών. Επίσης-άνδρες και γυναίκες αντιλαμβάνονται διαφορετικά την ποιότητα που αφορά στους γυμναστές και το υπόλοιπο προσωπικό του γυμναστηρίου.

description: The HOM-problem, which asks whether the image of a regular tree language under a tree homomorphism is again regular, is known to be decidable by [Godoy, Giménez, Ramos, Àlvarez: The HOM problem is decidable. STOC (2010)]. Research on the weighted version of this problem, however, is still in its infancy since it requires customized investigations. In this paper we address the weighted HOM-problem and strive to keep the underlying semiring as general as possible. In return, we restrict the input: We require the tree homomorphism h to be tetris-free, a condition weaker than injectivity, and for the given weighted tree automaton, we propose an ambiguity notion with respect to h. These assumptions suffice to ensure decidability of the thus restricted HOM-problem for all zero-sum free semirings by allowing us to reduce it to the (decidable) unweighted case.

description: Active galactic Nuclei (AGNs) with their relativistic jets pointed toward the observer, are a class of luminous gamma-ray sources commonly known as blazars. The study of this source class is essential to unveil the physical processes powering these extreme jets, to understand their cosmic evolution, as well as to indirectly probe the extragalactic background light. To do so, however, one needs to correctly classify and measure a redshift for a large sample of these sources. The Third Fermi-LAT Catalog of High-Energy Sources (3FHL) contains $1212$ blazars detected at energies greater than 10 GeV. However, $\sim$25% of these sources are unclassified and $\sim$56% lack redshift information. To increase the optical completeness of blazars in the 3FHL catalog, we devised an optical spectroscopic follow-up campaign using 4 $m$ and 8 $m$ telescopes. In this paper, we present the results of the last part of this campaign, where we observed 5 blazars using the 8 $m$ Gemini-S telescope in Chile. We report all 5 sources to be classified as BL Lacs, a redshift lower limit for 2 sources, and featureless spectra for the remaining 3 sources. We also performed a one-zone leptonic fit to the two sources with the redshift lower limits.

description: In Spring 2013, the LEECH (LBTI Exozodi Exoplanet Common Hunt) survey began its $\sim$130-night campaign from the Large Binocular Telescope (LBT) atop Mt Graham, Arizona. This survey benefits from the many technological achievements of the LBT, including two 8.4-meter mirrors on a single fixed mount, dual adaptive secondary mirrors for high Strehl performance, and a cold beam combiner to dramatically reduce the telescope's overall background emissivity. LEECH neatly complements other high-contrast planet imaging efforts by observing stars at L' (3.8 $μ$m), as opposed to the shorter wavelength near-infrared bands (1-2.4 $μ$m) of other surveys. This portion of the spectrum offers deep mass sensitivity, especially around nearby adolescent ($\sim$0.1-1 Gyr) stars. LEECH's contrast is competitive with other extreme adaptive optics systems, while providing an alternative survey strategy. Additionally, LEECH is characterizing known exoplanetary systems with observations from 3-5$μ$m in preparation for JWST.

description: Single-tape nondeterministic Turing machines that are allowed to replace the symbol in each tape cell only when it is scanned for the first time are also known as 1-limited automata. These devices characterize, exactly as finite automata, the class of regular languages. However, they can be extremely more succinct. Indeed, in the worst case the size gap from 1-limited automata to one-way deterministic finite automata is double exponential. Here we introduce two restricted versions of 1-limited automata, once-marking 1-limited automata and always-marking 1-limited automata, and study their descriptional complexity. We prove that once-marking 1-limited automata still exhibit a double exponential size gap to one-way deterministic finite automata. However, their deterministic restriction is polynomially related in size to two-way deterministic finite automata, in contrast to deterministic 1-limited automata, whose equivalent two-way deterministic finite automata in the worst case are exponentially larger. For always-marking 1-limited automata, we prove that the size gap to one-way deterministic finite automata is only a single exponential. The gap remains exponential even in the case the given machine is deterministic. We obtain other size relationships between different variants of these machines and finite automata and we present some problems that deserve investigation.

description: RXJ0848.6+4453 (Lynx W) at redshift 1.27 is part of the Lynx Supercluster of galaxies. Our analysis of stellar populations and star formation history in the cluster covers 24 members and is based on deep optical spectroscopy from Gemini North and imaging data from HST. Focusing on the 13 bulge-dominated galaxies for which we can determine central velocity dispersions, we find that these show a smaller evolution of sizes and velocity dispersions than reported for field galaxies and galaxies in poorer clusters. The galaxies in RXJ0848.6+4453 populate the Fundamental Plane similar to that found for lower redshift clusters with a zero point offset corresponding to an epoch of last star formation at z_form= 1.95+-0.2. The spectra of the galaxies in RXJ0848.6+4453 are dominated by young stellar populations at all galaxy masses and in many cases show emission indicating low level on-going star formation. The average age of the young stellar populations (estimated from H-zeta) is consistent with a major star formation episode 1-2 Gyr prior, which in turn agrees with z_form=1.95. Galaxies dominated by young stellar populations are distributed throughout the cluster. We speculate that low level star formation has not yet been fully quenched in the center of this cluster may be because the cluster is significantly poorer than other clusters previously studied at similar redshifts, which appear to have very little on-going star formation in their centers.

description: Using a yukawa type of metric we derive the kretschmann scalar for a general static black hole of a certain mass. The scalar gives the curvature of the space time as a function of the radial distance in the vicinity as well as inside of the black hole. Furthermore, the kretschmann scalar helps us understand the appearance of the black hole as a whole entity. It can be applied in solar mass size black holes, neutron stars or super massive black holes at the center of various galaxies. In an effort to investigate the connection of geometry to entropy and information, the kretschmann scalar for a solar mass yukawa schwarzschild and simple schwarzschild black holes are derived. Moreover, the dependence of the curvature on the entropy and number of information in nats is derived.

description: Research on the relationship between acculturation and youth internalizing disorders and youth academic performance has been conflicting. Some studies have shown that when Latinx parents and children have an acculturation gap, youth are more likely to exhibit anxious and depressive symptoms. Other studies show that youth who were more associated with their Latinx culture were more at risk for internalizing symptoms. Other research indicates that a narrower parent-child acculturation gap was associated with problem classroom behaviors and decreases in academic engagement for students. In another study, parent and youth acculturation gaps were associated with decreasing academic performance. The proposed study strives to examine how the parent-child acculturation gap is related to youth internalizing disorders and youth academic performance while controlling for parent education level, socioeconomic status, time in residence in the United States for parents and for youth, gender of parents and youth, and age of parents and youth.

description: We provide a method, based on automata theory, to mechanically prove the correctness of many numeration systems based on Fibonacci numbers. With it, long case-based and induction-based proofs of correctness can be replaced by simply constructing a regular expression (or finite automaton) specifying the rules for valid representations, followed by a short computation. Examples of the systems that can be handled using our technique include Brown's lazy representation (1965), the far-difference representation developed by Alpert (2009), and three representations proposed by Hajnal (2023). We also provide three additional systems and prove their validity.
