description: Interactive session presented at the UMD Libraries Research and Innovative Practice Forum, June 11, 2019.
description: Labor sustains cultural heritage and yet it is undervalued across libraries, archives, and museums (LAM). LAMs furthermore normalize contingency through practices like using short-term funding to create short-term positions in support of long-term programs and services. Conversations about labor practices and workers’ well-being in LAM often frame these issues as individual concerns. However, the impacts of LAM labor practices spread beyond the growing number of undervalued, invisible, and contingent workers that characterizes this field. In academic libraries, for example, workers with job protections (such as non-contingent faculty status) face mounting workloads as they find themselves unable to support and retain talented colleagues. These protected workers may also find it difficult to scale down their units’ responsibilities, even as undervalued and contingent workers depart. And when library workers depart or become burned out, what becomes of libraries’ ability to sustain access to information, teaching and learning, and high-quality research collections? In this session, we’ll discuss our recent work with the Digital Library Federation Working Group on Labor in Digital Libraries, Archives, and Museums (https://wiki.diglib.org/Labor), which focuses on two research areas: foregrounding the experiences of contingent and precarious workers; and developing a research agenda for valuing labor. We’ll briefly review each research activity in the first half of the session and devote the second half to discussion with participants. This session will be interactive but we hope you’ll stay!
title: Entwicklung einer Kalibriereinrichtung und eines Sensors für
magnetische Feldmessungen in einem Frequenzbereich von 100Hz bis

description: A new calibration facility was developed, tested, and installed at the premises of the Geomagnetic observatory in Niemegk to test induction coil magnetometers (search coils) in the frequency range 100Hz to 1 MHz. The new calibration facility is based on a Braunbeck coil, which extends existing installations based on a three-dimensional Helmholtz coil and a cylindrical coil which cover only the frequency range from a few mHz to 100 kHz. The new calibration coil is primarily needed to test magnetic field sensors used by the Geophysical Instrument Pool Potsdam for the so-called Radio Magnetotelluric (RMT) method. The RMT method uses electromagnetic fields transmitted by radio stations to infer the electrical conductivity distribution of the shallow subsurface (~1 m to 50 m). We present theoretical calculations to determine the parameters of the new calibration coil, which could be confirmed with measurements using an OMICRON BODE 100 spectrum analyser. The new coil system was also tested by calibrating two existing magnetic field sensors (METRONIX) MFS07 and SHFT-02e) with known response functions. We infer an overall accuracy of the new system of <0.05nT in amplitude and <0.5° in phase for frequencies < 700kHz and ≤0.05nT and ≤3° degrees for frequencies >	 700kHz. We also developed, tested and calibrated a new magnetic field sensor, using a set of three orthogonal toroidal coils (based on the antenna AN 200). The initial results look promising. The overall noise figures surpass those of the Metronix SHFT-02e sensor. The amplitude characteristic is slightly non-linear though, varying between 5 and 75 mV/nT over the frequency range 10 kHz to 1 MHz.
Where Voices are Heard: Historic Archaeology at the 19th Century Refugee Village at Tikal, Guatemala

description: In the late nineteenth century Maya refugees fleeing the violence of the Caste War of Yucatan (1847-1901) briefly reoccupied the ancient Maya ruins of Tikal. Unlike the numerous Yucatec refugee communities established in British Honduras, those who settled at Tikal combined with Lacandon Maya and Ladinos from Lake Petén Itza to form a small multiethnic village in the sparsely occupied Petén jungle of northern Guatemala. This dissertation directly investigates the materiality of the refugee experience and demonstrates methods in which archaeology can aid and inform the growing field of Refugee and Forced Migration Studies.
The relatively short occupation span combined with archaeologically intact households and depositional areas make the historic Tikal village the opportune location to directly explore the exploitation of frontier zones by refugee populations. A copious and varied assemblage of mass-produced consumer goods from around the globe was found in the houses and vast midden deposits of the Tikal village which reveals its interconnectedness to local, national, and international exchange markets as the historic inhabitants of Tikal were experiencing and actively engaging in incipient global capitalism (globalization) from the relative safety of the jungle frontier zone. How globally produced consumer goods were distributed and consumed by different societies in and around the frontier zone of nineteenth-century Petén elucidates patterns of economic choice and changing ethnic identities which is witnessed in refugee behaviors in the modern era.

description: Game developers cannot always meet the growing and changing needs of the gaming community, due to the often already overloaded schedules of developers. So-called modders can potentially assist game developers with addressing gamers' needs. Modders are enthusiasts who provide modifications or completely new content for a game. By supporting modders, game developers can meet the rapidly growing and varying needs of their gamer base. Modders have the potential to play a role in extending the life expectancy of a game, thereby saving game developers time and money, and leading to a better overall gaming experience for their gamer base. In this paper, we empirically study the metadata of 9,521 mods of the 20 most-modded games on the Nexus Mods distribution platform. Our goal is to provide useful insights into the modding community of the Nexus Mods distribution platform from a quantitative perspective, and to provide researchers with a solid foundation for future exploration of game mods. In doing so, game developers can potentially reduce development time and cost due to the increased replayability of their games through mods. We find that providing official support for mods can be beneficial for the perceived quality of the mods of a game. In addition, mod users are willing to submit bug reports for a mod. However, they often fail to do this in a systematic manner using the bug reporting tool of the Nexus Mods platform, resulting in low-quality bug reports which are difficult to resolve. Based on our findings, we recommend that game developers who desire an active modding community for their own games provide the modding community with an officially-supported modding tool. In addition, we recommend that mod distribution platforms, such as Nexus Mods, improve their bug reporting system to receive higher quality bug reports.

description: Biological materials are self-assembled with near-atomic precision in living cells, whereas synthetic 3D structures generally lack such precision and controllability. Recently, DNA nanotechnology, especially DNA origami technology, has been useful in the bottom-up fabrication of well-defined nanostructures ranging from tens of nanometres to sub-micrometres. In this Primer, we summarize the methodologies of DNA origami technology, including origami design, synthesis, functionalization and characterization. We highlight applications of origami structures in nanofabrication, nanophotonics and nanoelectronics, catalysis, computation, molecular machines, bioimaging, drug delivery and biophysics. We identify challenges for the field, including size limits, stability issues and the scale of production, and discuss their possible solutions. We further provide an outlook on next-generation DNA origami techniques that will allow in vivo synthesis and multiscale manufacturing.

description: Στη διατριβή αυτή μελετήθηκε η κλιματολογία και η ταξινόμηση των οπτικών και μικροφυσικών ιδιοτήτων των αιωρούμενων σωματιδίων με τη χρήση μεθόδων επίγειας τηλεπισκόπησης. Οι τεχνικές αυτές περιλαμβάνουν κατά βάση μία διάταξη lidar και ένα φωτόμετρο. Αν και η ανάλυση στο μεγαλύτερό της μέρος αφορά μετρήσεις του εργαστηρίου Φυσικής της Ατμόσφαιρας στην Θεσσαλονίκη, εντούτοις, στο πλαίσιο της διατριβής αξιοποιήθηκαν επίσης μετρήσεις του Ευρωπαϊκού δικτύου των lidar, European Lidar Network (EARLINET). Η ανάλυση συνοψίζεται σε τέσσερις κύριες θεματολογίες. Αρχικά, γίνεται παρουσίαση των διεργασιών συντήρησης και βελτιστοποίησης ενός συστήματος depolarization Raman lidar. Στη συνέχεια, περιγράφονται εκτενώς η μεθοδολογία και τα αποτελέσματα της κλιματολογικής ανάλυσης των μετρήσεων της χρονοσειράς του lidar και του φωτόμετρου στην περιοχή της Θεσσαλονίκης. Επιπρόσθετα, γίνεται υπολογισμός κάποιων μικροφυσικών ιδιοτήτων των αεροζόλ με τη συνδυαστική χρήση των δύο οργάνων και τα αποτελέσματα χρησιμοποιούνται για την αξιολόγηση ενός μοντέλου ποιότητας αέρα στην περιοχή της Θεσσαλονίκης. Τέλος, κάποια από τα προϊόντα τα οποία προέκυψαν από την ανάλυση, μαζί με μετρήσεις της βάσης δεδομένων του EARLINET αξιοποιήθηκαν στην αξιολόγηση δορυφορικών παρατηρήσεων.
description: The main topic of the thesis is the climatology and classification of the optical and microphysical properties of aerosols using ground-based remote sensing techniques. These techniques include mainly a lidar instrument and a sunphotometer. While the primary focus is on measurements performed at the Laboratory of Atmospheric Physics station in Thessaloniki, Greece, the thesis is also supplemented with public lidar data from the European Lidar Network (EARLINET) database. The analysis covers four main subjects. The maintenance and quality control procedures of a depolarization Raman lidar instrument located in the station of Thessaloniki, Greece, is presented first. Then, an extensive climatological analysis based on the aerosol optical and geometrical properties calculated from lidar and sunphotometer measurements of the station is performed. Aerosol microphysical properties obtained from combined lidar and sunphotometer measurements are applied in the evaluation of aerosol forecasts of an air quality model for Thessaloniki. Finally, some of the aforementioned lidar products, along with lidar data from the EARLINET database are applied for the validation of satellite products.

description: This study identifies the opportunities and constraints of the development of Malawi's soybean value chain. The results show that a significant supply gap exists for soybeans in Malawi with current production only meeting less than half of total demand. The industry's future expansion will be supported by existing improvements in yields and utilisation of the existing excess capacity to process soya into value-added products that attract better margins in domestic and export markets. The study demonstrates that that if implemented, the proposed reforms can improve the competitiveness of the soybean industry, resulting in economic growth, employment creation, and poverty reduction.

description: This theory explores the hypothetical concept of white holes, proposing they act as the inverse of black holes — repelling matter, energy, and even light. It considers the bending of space-time in reverse and proposes white holes as possibly existing on the opposite side of space-time fabric. Time dilation is also discussed in reverse, where time speeds up near a white hole.

description: The idea of transfer in reinforcement learning (TRL) is intriguing: being able to transfer knowledge from one problem to another problem without learning everything from scratch. This promises quicker learning and learning more complex methods. To gain an insight into the field and to detect emerging trends, we performed a database search. We note a surprisingly late adoption of deep learning that starts in 2018. The introduction of deep learning has not yet solved the greatest challenge of TRL: generalization. Transfer between different domains works well when domains have strong similarities (e.g. MountainCar to Cartpole), and most TRL publications focus on different tasks within the same domain that have few differences. Most TRL applications we encountered compare their improvements against self-defined baselines, and the field is still missing unified benchmarks. We consider this to be a disappointing situation. For the future, we note that: (1) A clear measure of task similarity is needed. (2) Generalization needs to improve. Promising approaches merge deep learning with planning via MCTS or introduce memory through LSTMs. (3) The lack of benchmarking tools will be remedied to enable meaningful comparison and measure progress. Already Alchemy and Meta-World are emerging as interesting benchmark suites. We note that another development, the increase in procedural content generation (PCG), can improve both benchmarking and generalization in TRL.
Concept mapping through a hub: coli-conc pilot study

description: Concept mapping through a hub is based on expressing each concept from any participating KOS through a description logic (DL) formula, a combination of elemental concepts drawn from a common classification of elemental concepts (such as a faceted classification). Complex DL formulas also give the role of each elemental concept in the compound. The resulting DL formulas are assembled in the hub; reasoning over DL formulas discovers concept relationships within and between KOS, including concept mappings. DL formulas are linked to concepts from participating KOS. KOS concepts linked to the same DL formula are mapped as skos:exactMatch. (Other types of SKOS mappings can be inferred from the relationships between DL formulas). Coli-conc is an integrated system for the collection, management, and mapping of KOS; it stores individual KOS and the mappings between KOS imported from various sources or created in Coli-conc with computer assistance. We will report on an exploratory qualitative study comparing mappings created through a hub with mappings available in Coli-conc. We drew a list of 50 examples for which Col-conc has three pairs of mappings {DDC — RVK, DDC — GND, RVK — GND} from the subject areas Psychology, Law, Education, Transportation, and Medicine. For each of the involved classes/ subject headings we created a simple DL formula. In the process we built an ad-hoc hierarchical list of elemental concepts. We will report observations and conclusions from inspecting the results, comparing the mappings based on DL formulas with the mappings given in Coli- conc.

Optimizing Fairness Measures Through Neural Networks and Subdominance Minimization
Creators: name: Vu, Linh
Publisher: name: University of Illinois at Chicago
Year: 2024

description: The pursuit of fairness in machine learning decisions is evolving, particularly in how fairness is balanced against other performance metrics like accuracy, demographic parity, equalized odds, and predictive value difference. Traditional methods often restrict to fixed trade-offs, potentially overlooking optimal fairness integrations. This thesis proposes a re-conceptualization of fairness through the lens of imitation learning, enhanced by the adoption of neural networks integrated with subdominance minimization. Unlike previous approaches that utilize logistic regression, our neural network model surpasses human decision benchmarks across multiple fairness and performance metrics. We demonstrate the superiority of this advanced model through comprehensive evaluations on standard datasets, showing significant improvements in decision fairness without compromising predictive accuracy.

Διερευνάται και ερμηνεύεται ο τρόπος με τον οποίο μεταβάλλεται η παρουσία των εθνικών σημείων ταυτότητας με την πάροδο του χρόνου καθώς και ποιες κατηγορίες προϊόντων απεικονίζονται κατά τη διάρκεια αυτής της περιόδου. Επιπρόσθετα, η μελέτη εξερευνά και συγκρίνει τα πολιτισμικά νοήματα που εντοπίζονται σε διαφημίσεις επίσημων φορέων, όπως ο Κυπριακός Οργανισμός Τουρισμού και οι Κυπριακές Αερογραμμές, καθώς και σε διαφημίσεις από μη-επίσημους φορείς, όπως η Μπύρα KEO και το Λαϊκό Καφεκοπτείο. Η έρευνα αξιοποιεί θεωρητικά εργαλεία από το χώρο της κονστρουκτιβιστικής θεωρίας για την εθνική ταυτότητα και της μελέτης των διαφημίσεων ως καθημερινά αντικείμενα ‘εμπορικού εθνικισμού’.

description: The current study seeks to identify what kinds of national identity signs are found in the images of commercial print advertisements in the Republic of Cyprus and which ones prevail. The study analyzed a corpus of n=1860 advertisements from State independence in 1960 till 2010. The aim was to investigate and interpret how the presence of national identity signs changes over time and what kind of product categories are depicted during this period. The study also aimed to identify what additional cultural meanings are found in print advertisements of official institutions, such as the Cyprus Tourism Organisation and Cyprus Airways, as well as compare them to the advertisements of two local non-state companies, KEO Beer and Laiko Kafekopteio (People’s coffee). The research falls under the constructivist conception of national identity and explores the reading of advertisements as part of commercial nationalism in everyday life. The study utilized a methodological approach, drawing from quantitative content analysis and semiotic analysis of advertisements. While the findings of the study depict predominant cultural values and characteristics of the Cypriot national identity, a mapping of the signs over time, portrays which ones are affected or not, throughout the socio-political development of the island from a post-colonial, independent state, to a member of the European Union.
Avant-garde film theory and praxis : an historical analysis of the narrative/anti-narrative debate
Creators: name: Insell, Maria Katherine
Publisher: name: University of British Columbia
Year: 2010

description: This analysis of the narrative/anti-narrative debate in avant-garde film theory and praxis is contextualized in terms of the developments in Modernism in the visual and plastic arts. The problems raised by the aesthetic strategies formal autonomy versus narrative appropriation are explored by examining several discrete historical paradigms rather than following a strict linear historical chronology of the development of Modernism and avant-garde practices. Therefore the late 1930's East/West debates between the four writers associated with the Frankfurt school were discussed because their discourses reveal a spectrum of possibilities which span each end of this polarized autonomy/efficacy argument. The discourses look at the issues of production aesthetics and reception aesthetics also. Within the parameters of East/West debates, the positioning of the subject in terms of "distracted habit" or "praxis" are critical considerations to a reception aesthetic. Another historical paradigm for this debate was the writing and film practice which emerged from the nexus of the events of May 1968. The East/West debates informed this writing and the development of the aesthetic questions raised by Peter Wollen in the "Two Avant-Gardes." Here the important issues of materialism, ontology, and the development of human perception are raised. The return to narrative is represented by the "second" avant-garde's film practice (Godard, Straub etc.) and informs the issues of new narrative in feminist film practices. This is narrative with a difference however. Here questions of language and the production of culture are critically examined and naturally the narrative/anti-narrative debate continues. Finally, these issues are brought foreword to the contemporary context and related specifically to the production of avant-garde film in Canada. One can see this contemporary debate in light of the past, however, the conclusions drawn by the thesis do not presume to resolve the narrative/anti-narrative debate or prescribe one particular approach, since this will arise from actual practice. The intention of the study is to introduce the central issues raised by social commitment/artistic autonomy and contribute to a better understanding of theoretical and practical implications of the debate over the use of narrative.

description: We present high-resolution observations made with the Very Large Array (VLA) in its A configuration at frequencies between 5 and 43 GHz of a sample of five massive young stellar objects (YSOs): LkHa101, NGC2024-IRS2, S106-IR, W75N and S140-IRS1. The resolution varied from 0.04 arcsec (at 43 GHz) to 0.5 arcsec (at 5 GHz), corresponding to a linear resolution as high as 17 AU for our nearest source. A MERLIN observation of S106-IR at 23 GHz with 0.03-arcsec resolution is also presented. S106-IR and S140-IRS1 are elongated at 43 GHz perpendicular to their large scale bipolar outflows. This confirms the equatorial wind picture for these sources seen previously in MERLIN 5 GHz observations. The other sources are marginally resolved at 43 GHz. The spectral indices we derive for the sources in our sample range from +0.2 to +0.8, generally consistent with ionized stellar winds. We have modelled our sources as uniform, isothermal spherical winds, with LkHa101 and NGC2024-IRS2 yielding the best fits. However, in all cases our fits give wind temperatures of only 2000 to 5000 K, much less than the effective temperatures of main-sequence stars of the same luminosity, a result which is likely due to the clumpy nature of the winds.

description: B-doped $δ$-layers were fabricated in Si(100) using BCl$_{3}$ as a dopant precursor in ultrahigh vacuum. BCl$_{3}$ adsorbed readily at room temperature, as revealed by scanning tunneling microscopy (STM) imaging. Annealing at elevated temperatures facilitated B incorporation into the Si substrate. Secondary ion mass spectrometry (SIMS) depth profiling demonstrated a peak B concentration $>$ 1.2(1) $\times$ 10$^{21}$ cm$^{-3}$ with a total areal dose of 1.85(1) $\times$ 10$^{14}$ cm$^{-2}$ resulting from a 30 L BCl$_{3}$ dose at 150 $^{\circ}$C. Hall bar measurements of a similar sample were performed at 3.0 K revealing a sheet resistance of $R_{\mathrm{s}}$ = 1.91 k$Ω\square^{-1}$, a hole concentration of $n$ = 1.90 $\times$ 10$^{14}$ cm$^{-2}$ and a hole mobility of $μ$ = 38.0 cm$^{2}$V$^{-1}$s$^{-1}$ without performing an incorporation anneal. Further, the conductivity of several B-doped $δ$-layers showed a log dependence on temperature suggestive of a two-dimensional system. Selective-area deposition of BCl$_{3}$ was also demonstrated using both H- and Cl-based monatomic resists. In comparison to a dosed area on bare Si, adsorption selectivity ratios for H and Cl resists were determined by SIMS to be 310(10):1 and 1529(5):1, respectively, further validating the use of BCl$_{3}$ as a dopant precursor for atomic precision fabrication of acceptor-doped devices in Si.

description: This article examines how a breakdown of a locally Lorentz invariant, point-like description of nature at tiny space-time intervals would translate into a distinctive set of signals in the primordial power spectrum generated by inflation. We examine the leading irrelevant operators that are consistent with the spatial translations and rotations of a preferred, isotropically expanding, background. A few of the resulting corrections to the primordial power spectrum do not have the usual oscillatory factor, which is sometimes taken to be characteristic of a "trans-Planckian" signal. Perhaps more interestingly, one of these leading irrelevant operators exactly reproduces a correction to the power spectrum that occurs in effective descriptions of the state of the field responsible for inflation.

description: Scanning Microwave Microscopy (SMM) is a nanoscale imaging technique that combines the lateral resolution of Atomic Force Microscopy (AFM) with the high measurement precision of microwave analysis at GHz frequencies, provided by Vector Network Analyzers (VNA). SMM enables measuring complex materials properties for nano-electronics, materials science, and life science applications. SMM operates at broadband frequencies between 1 GHz and 20 GHz. We developed novel calibration workflows for complex impedance imaging1-2 and dielectric quantification3. Various nanodevices are studied including dopant profiling layers and high voltage transistors4,5. Based on the high frequency the laborious fabrication of back electrode contacts is not required, making it an easily applicable tool for electrical characterization of nanodevices. The capability of the electromagnetic waves to penetrate the surface of the sample under study allows the technique to be used to selectively sense sub-surface features6. The sub-surface and quantitative resistivity measurement capabilities are demonstrated for silicon back-wafer imaging and semiconductor failure analysis. As will be shown as an ultimate limit even atomically thin regions of dopant atoms in silicon can be electrically characterized and localized in 3 dimensions with nm resolution7. Such dopant structures are building blocks of quantum devices for physics research and it is anticipated that they will also serve as key components of devices for next generation classical and quantum information processing.

description: We consider the properties weak cancellation, K_1-surjectivity, good index theory, and K_1-injectivity for the class of extremally rich C*-algebras, and for the smaller class of isometrically rich C*-algebras. We establish all four properties for isometrically rich C*-algebras and for extremally rich C*-algebras that are either purely infinite or of real rank zero, K_1-injectivity in the real rank zero case following from a prior result of H. Lin. We also show that weak cancellation implies the other properties for extremally rich C*-algebras and that the class of extremally rich C*-algebras with weak cancellation is closed under extensions. Moreover, we consider analogous properties which replace the group K_1(A) with the extremal K-set K_e(A) as well as two versions of K_0-surjectivity.

Επιδιώξαμε να εμπλέξουμε τους μαθητές σε διαδικασίες συγκρότησης νοήματος στo μάθημα της λογοτεχνίας μέσα από τη χρήση κινηματογραφικών ταινιών. Εφαρμόσαμε μια έρευνα-δράση και μελετήσαμε την ανταπόκριση των μαθητών σε δραστηριότητες στις οποίες συνυπήρχαν κινηματογραφικές ταινίες, τηλεοπτικές σειρές και λογοτεχνικά κείμενα. Μας απασχόλησε αν η ερμηνεία των μαθητών χαρακτηρίζεται από κριτική ματιά ή επιφανειακή ανάγνωση των κειμένων, αν οι μαθητές λαμβάνουν υπόψη το ιστορικό, κοινωνικό και πολιτισμικό πλαίσιο και αν κατανοούν τις τεχνικές και τις συμβάσεις των λεκτικών, οπτικοακουστικών και πολυτροπικών κειμένων αυτοτελώς ή και σε σύγκριση. Επιχειρήσαμε να απαντήσουμε στο ερώτημα με ποιους τρόπους η κινηματογραφική ταινία, η τηλεοπτική σειρά και άλλα πολυτροπικά κείμενα μπορούν να ενταχτούν οργανικά και να υπηρετήσουν τους στόχους της λογοτεχνικής εκπαίδευσης στη δευτεροβάθμια εκπαίδευση.
description: This dissertation explores the use of film as a text in teaching literature in high school in the perspective of critical literacy. The aim was to engage students in understanding literature through the use of film. In this research project we adopted the action-research methodology and we studied students’ response to activities which involved films, TV series and literary texts. We explored whether the students’ interpretation is a true critical reading position or a typical reader response to texts. Furthermore we investigated whether students consider the historical, social and cultural context and if they comprehend the language of the literary or multimodal texts independently or in comparison. The overall aim was to demonstrate how film can be integrated into curriculum to serve the teaching literature aims in secondary education in Greece.

description: Data publication is increasingly regarded as important scientific achievement and data publications are now fully citable in journal articles. This paper focuses on improving the reusability of data publications by providing comprehensive data descriptions complementary to standardized metadata. In this context, data reports proved to be a helpful tool to fill the gap between restricted ’README’ information on one hand and preparing an extended peer-reviewed data article on the other hand.
Feedback from an O star formed in a filament

description: We explore a simple semi-analytic model for what happens when an O star (or cluster of O stars) forms in an isolated filamentary cloud. The model is characterised by three configuration parameters: the radius of the filament, R_FIL, the mean density of H_2 in the filament, n_FIL, and the rate at which the O star emits ionising photons, Ndot_LyC. We show that for a wide range of these configuration parameters, ionising radiation from the O star rapidly erodes the filament, and the ionised gas from the filament disperses into the surroundings. Under these circumstances the distance from the O star to the ionisation front (IF) is given approximately by L ~ 5.2 pc [R_FIL/0.2pc]^-1/6 [n_FIL/10^4cm^-3]^-1/3 [Ndot_LyC/10^49s^-1]^1/6 [t/Myr]^2/3, and we derive similar simple power-law expressions for other quantities, for example the rate at which ionised gas boils off the filament, and the mass of the shock-compressed layer (SCL) that is swept up behind the IF. We show that a very small fraction of the ionising radiation is expended locally, and a rather small amount of molecular gas is ionised and dispersed. We discuss some features of more realistic models, and the extent to which they might modify or invalidate the predictions of this idealised model. In particular we show that, for very large R_FIL and/or large n_FIL and/or low Ndot_LyC, continuing accretion onto the filament might trap the ionising radiation from the O star, slowing the erosion of the filament even further.

Investigating the Role of NOX2 and Fatty Infiltration in Obesity-Induced Atrial Fibrillation

description: Obesity is linked to an increased risk of atrial fibrillation (AF) via increased oxidative stress. While NADPH oxidase II (NOX2), a major source of oxidative stress and reactive oxygen species (ROS) in the heart predisposes to AF, the underlying mechanisms remain unclear. Here, we studied NOX2-mediated ROS production in obesity-mediated AF using Nox2-knock-out (KO) mice and mature human induced pluripotent stem cell-derived atrial cardiomyocytes (hiPSC-aCMs). Diet-induced obesity (DIO) mice and human atrial induced pluripotent stem cell-derived cardiomyocytes (hiPSC-aCMs) treated with palmitic acid (PA) were infused with a NOX blocker (apocynin) and a NOX2-specific inhibitor, respectively. We showed that NOX2 inhibition normalized atrial action potential duration and abrogated obesity-mediated ion channel remodeling with reduced AF burden.
Additionally, serum and heart fractions from DIO mice show increased levels of saturated fatty acids (SFA), monounsaturated fatty acids (MUFA), and omega-6 polyunsaturated fatty acids (n-6 PUFA) compared to lean controls. We, thus, hypothesize that obesity-induced atrial remodeling is mediated by the differential effects of chronic SFA, MUFA, and n-6 PUFAs using HiPSC-aCMs. HiPSC-aCMs are treated with conjugated PA, oleic acid (OA), or linoleic acid (500 µM) chronically, and changes in atrial ion channel expression and function, lipid peroxidation, and oxidative stress are evaluated using cellular patch clamping, multi-electrode arrays (MEA), qPCR, and western blotting.
The direct impact of our studies will enable the development of mechanism-based therapeutic approaches for AF in obese patients, ultimately aiming to improve patient outcomes and reduce the burden of this arrhythmia.

description: Neutrino oscillation experiments and direct bounds on absolute masses constrain neutrino mass differences to fall into the microwave energy range, for most of the allowed parameter space. As a consequence of these recent phenomenological advances, older constraints on radiative neutrino decays based on diffuse background radiations and assuming strongly hierarchical masses in the eV range are now outdated. We thus derive new bounds on the radiative neutrino lifetime using the high precision cosmic microwave background spectral data collected by the Far Infrared Absolute Spectrophotometer instrument on board of Cosmic Background Explorer. The lower bound on the lifetime is between a few x 10^19 s and 5 x 10^20 s, depending on the neutrino mass ordering and on the absolute mass scale. However, due to phase space limitations, the upper bound in terms of the effective magnetic moment mediating the decay is not better than ~ 10^-8 Bohr magnetons. We also comment about possible improvements of these limits, by means of recent diffuse infrared photon background data. We compare these bounds with pre-existing limits coming from laboratory or astrophysical arguments. We emphasize the complementarity of our results with others available in the literature.
