description: In this dissertation, I investigate the authentic learning experiences of students participating in the Engineering Projects in Community Service (EPICS) program at Purdue University within the framework of authentic education. Utilizing a quantitative approach, the study assesses the performance of new and returning students across five key outcomes that measure authentic learning during a single semester. The analysis of variance (ANOVA) revealed significant main effects for time of assessment and type of student on performance, with an overall improvement in all outcomes observed from mid-term to final evaluations and returning students typically outperforming new students. Interaction effects between time and type were also examined, revealing subtle yet complex dynamics in students’ learning trajectories. The findings hold implications for enhancing authentic learning, especially in engineering design contexts, and offer insights to guide future implementation of and improvements to authentic education initiatives, particularly the EPICS program. Despite certain limitations, the research opens avenues for future investigations into diverse aspects of authentic education in STEM and beyond.

description: Universal properties of mass-imbalanced three-body systems in 2D are studied using zero-range interactions in momentum space. The dependence of the three-particle binding energy on the parameters (masses and two-body energies) is highly non-trivial even in the simplest case of two identical particles and a distinct one. This dependence is parametrized for ground and excited states in terms of {\itshape supercircles} functions in the most general case of three distinguishable particles.

LAr scintillation light measurements taken during one year by ProtoDUNE Dual Phase at CERN
Creators: name: Ros, Ana Gallego
Publisher: name: Zenodo
Year: 2020

description: DUNE is a dual-site experiment for neutrino science and searches for physics BSM. The Far Detector will consist of four 10 kton fiducial mass LAr TPCs. The photon detection system (PDS) embedded within the detector adds precise timing capabilities for non-beam events. The ProtoDUNE Dual Phase (DP) detector is a 300 ton LAr TPC currently operating at the CERN Neutrino Platform. The PDS is formed by 36 8-inch cryogenic photomultiplier tubes (PMTs) and includes an LED-based fiber calibration system. The topic of this poster is the ProtoDUNE-DP PDS performance using cosmic ray data taken during one year at CERN. Studies on the PMT gain stability, the scintillation light profile and electroluminescence light detection (from the gas, more than 6 meters away from the PMTs) are shown. Moreover, the first analyses on the low energy background and the muon-detection efficiency using the PDS are presented.

description: This deliverable is a guidebook to support the successful implementation of the Sectoral Conversations for industry, mobility & transport, buildings, and agriculture, land use, and forestry under the NDC ASPECTS project. The purpose of the Sectoral Conversations is to provide a space for inter- and transdisciplinary exchange within the project and with project-external sectoral experts. It provides an opportunity to share (interim) results from the outset with different disciplines and external stakeholders. Their feedback might help to hone research questions and reconfigure ongoing analyses so that they speak to each other, thus maximizing their policy and academic relevance.
The nEXO Outer Detector and Muon Veto
Creators: name: Nexo Collaboration

Publisher: name: Zenodo
Year: 2020

description: The nEXO experiment is a next-generation neutrinoless double-beta decay search with the isotope $^{136}$Xe and a half-life sensitivity goal of 10$^{28}$ years. The nEXO experiment plans to take full advantage of the self-shielding effects of the liquid xenon and exploit as large a fiducial mass as possible; therefore minimizing external contributions to the background radiation entering the nEXO time projection chamber (TPC) is required. In order to accomplish this task, an outer detector, in which the nEXO TPC and cryostat are fully submerged, consisting of a tank filled with ultra-pure deionized water and instrumented with 8-inch PMTs will provide the outer shielding and act as a muon veto for nEXO. The initial design along with the passive and active shielding capability for external backgrounds will be presented.

description: We present the first extensive study of the coronal line variability in an active galaxy. Our data set for the nearby source NGC 4151 consists of six epochs of quasi-simultaneous optical and near-infrared spectroscopy spanning a period of about eight years and five epochs of X-ray spectroscopy overlapping in time with it. None of the coronal lines showed the variability behaviour observed for the broad emission lines and hot dust emission. In general, the coronal lines varied only weakly, if at all. Using the optical [Fe VII] and X-ray O VII emission lines we estimate that the coronal line gas has a relatively low density of n~10^3 cm^-3 and a relatively high ionisation parameter of log U~1. The resultant distance of the coronal line gas from the ionising source is about two light years, which puts this region well beyond the hot inner face of the obscuring dusty torus. The high ionisation parameter implies that the coronal line region is an independent entity rather than part of a continuous gas distribution connecting the broad and narrow emission line regions. We present tentative evidence for the X-ray heated wind scenario of Pier & Voit. We find that the increased ionising radiation that heats the dusty torus also increases the cooling efficiency of the coronal line gas, most likely due to a stronger adiabatic expansion.

Measuring the proton-argon cross section at ProtoDUNE-SP
Creators: name: Heng-Ye Liao
Publisher: name: Zenodo
Year: 2020

description: Recent neutrino oscillation experiments have ushered in a new era with precision measurements employed in the search for CP violation and mass hierarchy. The Deep Underground Neutrino Experiment (DUNE) is a next generation long-baseline neutrino experiment in USA. The single-phase liquid argon far-detector prototype at CERN (ProtoDUNE-SP) is a critical milestone for the DUNE experiment. ProtoDUNE-SP utilizes the CERN H4 beam line with known particle type (hadrons and electrons) and incident energy. This provides a controlled environment for better understanding of the interactions taking place within a LArTPC detector. Protons are one of the final state particles in neutrino charged current interactions and hence they play an essential role in reconstructing the neutrino total energy in the interactions. I will present our progress on the proton-argon cross section, including the selection of beam protons, space charge calibration, calorimetric reconstruction, and calculation of cross section.

Updated results on reactor antineutrino oscillation amplitude and frequency for 2900 days at RENO
Creators: name: Dongha Lee
Publisher: name: Zenodo
Year: 2020

description: The RENO experiment has precisely measured the amplitude and frequency of reactor antineutrino oscillaion at Hanbit Nuclear Power Plant since Aug. 2011. The previously measured values based on ~2200 days of data were reported for publication in 2018. Since then, an additional ~700 day data has been analyzed with improved methods to obtain an updated result. The additional data were taken during a period of rather minimal thermal power by the reactors, corresponding to only one or two reactors in operation. In that period, we have measured relatively low fluxes of reactor antineutrinos. In this presentation, we report updated measurement of reactor antineutrino oscillation obtained from the 2900 day data and variation of their measured rates.
D4.1 - What determines climate ambition? Analysing NDC enhancement with a mixed-method design

description: The study presents four key findings. First, based on prior academic and policy literature, we establish three categories of potential drivers and barriers to NDC enhancement: political institutions, the economy, and structural factors. Second, we identify the key role of democratic institutions through quantitative and qualitative methods. We find that more democratic countries were more likely to enhance their 2030 emission targets in the updated NDCs. The qualitative part of the deliverable supports this by finding that open and transparent stakeholder consultations were beneficial for the enhancement of greenhouse gas emission targets in updated NDCs. Saudi Arabia, however, is a key outlier as it enhanced its 2030 NDC mitigation target within completely closed decision-making institutions. Third, we establish that government and stakeholder concerns about the potential negative impacts of the green transition constitute a key barrier to continued NDC enhancement. The quantitative analysis shows that governments in countries with high economic fast-growing economies tended to keep their pledges the same or even reduced ambition. Qualitative interviews indicated that this may be due to worries about increasing GHG emissions and the effects of the low emission transition on future economic growth. The mixed-method findings suggest that the enhancement of climate pledges is supported by open political processes that manage to take into account concerns about economic development. Finally, we do not find that structural factors, such as fossil fuel production and physical impacts of climate change constitute a significant barrier to NDC enhancement, although they may determine the initial level of climate ambition in the first NDC.
On a test on switching separability of graphs modulo $q$

description: We consider the graphs whose edges are marked by the integers (weights) from $0$ to $q-1$ (zero corresponds to no-edge). Such graph is called additive if its vertices can be marked in such a way that the weight of every edge is equal to the modulo-$q$ sum of weights of the two incident vertices. By a switching of a graph we mean the modulo-$q$ sum of the graph with some additive graph on the same vertex set. A graph with $n$ vertices is called switching separable if some of its switchings does not have a connected component of order $n$ or $n-1$. We consider the following test for the switching separability: if removing any vertex of a graph $G$ results in a switching separable graph, then $G$ is switching separable itself. We prove this test for odd $q$ and characterize the exceptions when $q$ is even. We establish a connection between the switching separability of a graph and the reducibility of $(n-1)$-ary quasigroups constructed from this graph.

description: The effect of femtosecond laser irradiation on bulk and single-layer MoS2 on silicon oxide is studied. Optical, Field Emission Scanning Electron Microscopy (FESEM) and Raman microscopies were used to quantify the damage. The intensity of A1g and E2g1 vibrational modes was recorded as a function of the number of irradiation pulses. The observed behavior was attributed to laser-induced bond breaking and subsequent atoms removal due to electronic excitations. The single-pulse optical damage threshold was determined for the monolayer and bulk under 800nm and 1030nm pulsed laser irradiation and the role of two-photon versus one photon absorption effects is discussed.

description: Mesoscopic thermoelectric heat engine is much anticipated as a device that allows us to utilize with high efficiency wasted heat inaccessible by conventional heat engines. However, the derivation of the heat current in this engine seems to be either not general or described too briefly, even inappropriate in some cases. In this paper, we give a clear-cut derivation of the heat current of the engine with suitable assumptions beyond the linear-response regime. It resolves the confusion in the definition of the heat current in the linear-response regime. After verifying that we can construct the same formalism as that of the cyclic engine, we find the following two interesting results within the Landauer-Büttiker formalism: the efficiency of the mesoscopic thermoelectric engine reaches the Carnot efficiency if and only if the transmission probability is finite at a specific energy and zero otherwise; the unitarity of the transmission probability guarantees the second law of thermodynamics, invalidating Benenti et al.'s argument in the linear-response regime that one could obtain a finite power with the Carnot efficiency under a broken time-reversal symmetry. These results demonstrate how quantum mechanics constraints thermodynamics.

Profondo conoscitore della scuola italiana e dei sistemi scolastici a livello mondiale, particolarmente attento alle dimensioni comparative in ambio scolastico, al nesso istruzione-sviluppo economico, all’innovazione e alla sperimentazione in campo educativo (in primo luogo, per quanto riguarda l’utilizzazione delle nuove tecnologie a fini didattici), Gozzer è stato consigliere di numerosi ministri della Pubblica Istruzione ed uno dei più attivi protagonisti del dibattito pedagogico nel secondo Novecento.

description: ZICOS is scintillator experiment for 0$\nu \beta \beta$ of $^{96}$Zr. In order to achieve sensitivity over $10^{27}$ years, ZICOS will use tons of $^{96}$Zr, and need to remove $^{208}$Tl backgrounds as observed by KamLAND-Zen one order of magnitude. For this purpose, we have developed new technique to distinguish the signal and background using Cherenkov light, and succeeded that 93% of $^{208}$Tl events could be removed even though remaining 80% of 0$\nu \beta \beta$ signal using Monte Carlo simulation. In order to realize this technique, we have to select PMT which receives Cherenkov lights. From recent measurement using $^{90}$Sr $\beta$ source, a clear pulse of Cherenkov light was observed among scintillation, and pulse shape discrimination was established. Here, we report current status and discuss about plans to demonstrate the background reduction and to observe 2$\nu \beta \beta$ decay of $^{96}$Zr.
Darboux transformations for CMV matrices

description: We develop a theory of Darboux transformations for CMV matrices, canonical representations of the unitary operators. In perfect analogy with their self-adjoint version -- the Darboux transformations of Jacobi matrices -- they are equivalent to Laurent polynomial modifications of the underlying measures. We address other questions which emphasize the similarities between Darboux transformations for Jacobi and CMV matrices, like their (almost) isospectrality or the relation that they establish between the corresponding orthogonal polynomials, showing also that both transformations are connected by the Szegö mapping. Nevertheless, we uncover some features of the Darboux transformations for CMV matrices which are in striking contrast with those of the Jacobi case. In particular, when applied to CMV matrices, the matrix realization of the inverse Darboux transformations -- what we call 'Darboux transformations with parameters' -- leads to spurious solutions whose interpretation deserves future research. Such spurious solutions are neither unitary nor band matrices, so Darboux transformations for CMV matrices are much more subject to the subtleties of the algebra of infinite matrices than their Jacobi counterparts. A key role in our theory is played by the Cholesky factorizations of infinite matrices. Actually, the Darboux transformations introduced in this paper are based on the Cholesky factorizations of degree one Hermitian Laurent polynomials evaluated on CMV matrices. We also show how these transformations can be generalized to higher degree Laurent polynomials, as well as to the extension of CMV matrices to quasi-definite functionals -- what we call 'quasi-CMV' matrices.

Millicharged Particles and Inelastic Dark Matter at the DUNE Near-Detector Complex
Creators: name: Yu-Dai Tsai

Publisher: name: Zenodo
Year: 2020

description: The DUNE Near-Detector (ND) complex, including LArTPC and HPgTPC detectors, provides a powerful multi-purpose facility to search for dark-sector particles, produced when 120 GeV proton beam (~10^21 POT/yr) hits the LBNF target. In this talk, I will discuss two types of searches: decay and scattering. For the decay search, I will talk about a sub-GeV dark matter (DM) candidate, inelastic dark matter (iDM), that also has a long-lived state to be searched for in DUNE. DUNE can provide one of the strongest probes of iDM in the MeV-GeV regime. For the scattering search, I will present a study of the millicharged particle (MCP), a stable particle carrying fractional charges in the LArTPC detector. DUNE can provide leading sensitivity to MCPs and strongly interacting DM that cannot be seen in traditional direct-detection experiments. Finally, I briefly discuss scattering-plus-decay studies.

description: Diese Arbeit befasst sich mit dem Problem der geringen Akzeptanz von Werkzeugen zur statischen Analyse von Sicherheitstests (SAST) bei den Benutzern aufgrund von Problemen mit der Benutzerfreundlichkeit, wie z. B. falschen Warnungen und langen Laufzeiten. Um diese Probleme zu beheben, werden in dieser Arbeit Methoden und Werkzeuge vorgeschlagen, die die Anpassung der Taint-Analyse an die Zielprogramme (halb-)automatisieren und so die Konfiguration der Werkzeuge für einen breiteren Benutzerkreis erleichtern. Eine empirische Studie wird durchgeführt, um die Bedürfnisse der Benutzer besser zu verstehen, und die Ergebnisse werden verwendet, um SWAN vorzuschlagen, einen vollautomatischen maschinellen Lernansatz zur Ableitung sicherheitsrelevanter Methoden für die Spezifikation von Taint-Flows. Um die Einschränkungen von SWAN zu verbessern, wird ein halbautomatischer aktiver Machine-Learning-Ansatz namens SWANAssist vorgeschlagen. Um einen brauchbaren Weg für die Konfiguration der Taint-Analyse zu bieten, wird fluentTQL, eine entwicklerorientierte, domänenspezifische Sprache für die Spezifikation von Taint-Flows, vorgeschlagen und in einer Benutzerstudie als hervorragend brauchbar befunden. Die Ergebnisse zeigen, dass die Anpassung von Taint-Analyse-Tools für Benutzer durch maschinelles Lernen und benutzerzentriertes Design verbessert werden kann.
description: This thesis focuses on the issue of low acceptance and popularity of static analysis security testing (SAST) tools among users due to usability problems, such as false warnings and long-running times. To address these issues, the thesis proposes methods and tools to (semi-)automate the adaptation of taint analysis to target programs, making it easier for a broader range of users to configure the tools. An empirical study is conducted to better understand the needs of users, and the results are used to propose SWAN, a fully automatic machine-learning approach for inferring security-relevant methods for taint-flow specification. To improve the limitations of SWAN, a semi-automated active machine-learning approach is proposed called SWANAssist. To provide a usable way for configuring taint analysis, fluentTQL, a developer-oriented domain-specific language for specifying taint-flows, is proposed and found to have excellent usability in a user study. The results demonstrate that adaptation of taint analysis tools can be improved for users via machine-learning and user-centric design.

description: The active simultaneously transmitting/reflecting surface (ASTARS) is considered a promising technique to achieve full spatial coverage and overcome multiplicative fading caused by cascaded paths. This paper investigates the performance of ASTARS-assisted rate-splitting multiple-access networks (ASTARS-RSMA) with multiple transmission users (TUs) and reflection users (RUs). The energy-splitting configurations of ASTARS and the effects of imperfect/perfect successive interference cancellation (SIC) on ASTARS-RSMA networks are considered in the analysis. We derive new exact and asymptotic expressions of the outage probability with imperfect/perfect SIC for TUs and RUs. On this basis, we further calculate the diversity orders of TUs and RUs. Moreover, the system throughput and energy efficiency (EE) of ASTARS-RSMA are evaluated in the delay-limited mode. The simulation results confirm the accuracy of the theoretical expressions and show that (i) the outage probability and system throughput with imperfect/perfect SIC of ASTARS-RSMA exceed that of passive simultaneously transmitting/reflecting surface (PSTARS)-assisted RSMA when the number of elements is not too large; (ii) although ASTARS increases power consumption compared to PSTARS, it can bring further EE improvements to RSMA networks.

description: Using the time-dependent density-matrix renormalization group (tDMRG), we study the time evolution of electron wave packets in one-dimensional (1D) metal-superconductor heterostructures. The results show Andreev reflection at the interface, as expected. By combining these results with the well-known single-spin-species electron-hole transformation in the Hubbard model, we predict an analogous spin Andreev reflection in metal-Mott insulator heterostructures. This effect is numerically confirmed using 1D tDMRG, but it is expected to be present also in higher dimensions, as well as in more general Hamiltonians. We present an intuitive picture of the spin reflection, analogous to that of Andreev reflection at metal-superconductors interfaces. This allows us to discuss a novel antiferromagnetic proximity effect. Possible experimental realizations are discussed.

description: Purpose: The call for data-driven health care has been bolstered by the digitization of medical records, quality initiatives, and payment reform. Administrative databases and clinical registries are increasingly being used to study oropharyngeal dysphagia and to facilitate data-driven decision making. The objective of this work was to summarize key findings, etiologies studied, data sources used, study objectives, and quality of evidence of all original research articles that have investigated oropharyngeal dysphagia or aspiration pneumonia using administrative or clinical registry data to date.Method: A literature search was completed in MEDLINE, Scopus, and Google Scholar (January 1, 1990, to February 1, 2017). Each study that met inclusion criteria was rated for quality of evidence on a 5-point scale.Results: Eighty-four research articles were included in the final analysis (n = 221–1,649,871). Over the past 20 years, the number of new publications in this area has quintupled. Most of the administrative database and clinical registry studies of dysphagia have been retrospective cohort studies and cross-sectional studies and limited to quality of evidence levels of 3–4. In these studies, much has been learned about risk factors for dysphagia and pneumonia in defined populations and health care costs and usage. Little has been gleaned from these studies regarding swallowing physiology or dysphagia management.Conclusions: Investigators are just beginning to develop the methods to study oropharyngeal dysphagia using administrative data and clinical registries. Future research is needed in all areas, from the fundamental issue of how to identify individuals with dysphagia with high sensitivity in these data sets to evaluating treatment effectiveness.

For the first time in the far-IR domain, we spatially resolve the emission associated with the bright H2 shocked regions "Peak 1" and "Peak 2" from that of the Hot Core and ambient cloud. We analyze the ~54-310um spectra taken with the PACS and SPIRE spectrometers. More than 100 lines are detected, most of them rotationally excited lines of 12CO (up to J=48-47), H2O, OH, 13CO, and HCN. Peaks 1/2 are characterized by a very high L(CO)/L(FIR)~5x10^{-3} ratio and a plethora of far-IR H2O emission lines. The high-J CO and OH lines are a factor ~2 brighter toward Peak 1 whereas several excited H2O lines are ~50% brighter toward Peak 2. A simplified non-LTE model allowed us to constrain the dominant gas temperature components. Most of the CO column density arises from Tk~200-500 K gas that we associate with low-velocity shocks that fail to sputter grain ice mantles and show a maximum gas-phase H2O/CO~10^{-2} abundance ratio. In addition, the very excited CO (J>35) and H2O lines reveal a hotter gas component (Tk~2500 K) from faster (v_S>25 km/s) shocks that are able to sputter the frozen-out H2O and lead to high H2O/CO>~1 abundance ratios. The H2O and OH luminosities cannot be reproduced by shock models that assume high (undepleted) abundances of atomic oxygen in the preshock gas and/or neglect the presence of UV radiation in the postshock gas. Although massive outflows are a common feature in other massive star-forming cores, Orion BN/KL seems more peculiar because of its higher molecular luminosities and strong outflows caused by a recent explosive event.

description: Purpose: A striking characteristic of the social communication deficits in individuals with autism is atypical patterns of eye contact during social interactions. We used eye-tracking technology to evaluate how the number of human figures depicted and the presence of sharing activity between the human figures in still photographs influenced visual attention by individuals with autism, typical development, or Down syndrome. We sought to examine visual attention to the contents of visual scene displays, a growing form of augmentative and alternative communication support.Method: Eye-tracking technology recorded point-of-gaze while participants viewed 32 photographs in which either 2 or 3 human figures were depicted. Sharing activities between these human figures are either present or absent. The sampling rate was 60 Hz; that is, the technology gathered 60 samples of gaze behavior per second, per participant. Gaze behaviors, including latency to fixate and time spent fixating, were quantified.Results: The overall gaze behaviors were quite similar across groups, regardless of the social content depicted. However, individuals with autism were significantly slower than the other groups in latency to first view the human figures, especially when there were 3 people depicted in the photographs (as compared with 2 people). When participants’ own viewing pace was considered, individuals with autism resembled those with Down syndrome.Conclusion: The current study supports the inclusion of social content with various numbers of human figures and sharing activities between human figures into visual scene displays, regardless of the population served. Study design and reporting practices in eye-tracking literature as it relates to autism and Down syndrome are discussed.

Search for astronomical neutrino from the Gamma-ray burst with Super-Kamiokande
Creators: name: Harada, Masayuki
Publisher: name: Zenodo

description: Gamma-ray bursts (GRB) are one of the most luminous astronomical events in the universe. GRB is a candidate for sources of ultra-high energy cosmic rays, but the detailed mechanism of emission of gamma-ray is not determined well. Neutrinos are expected to be emitted from the GRB object for many theoretical models. Therefore, the detection of neutrino enables us to discriminate among prompt emission mechanisms. The Super-Kamiokande is a large water-Cherenkov detector, which consists in 50 kton ultra-pure water and about 13000 Photomultiplier tubes. The detector is running since 1996, and it has a sensitivity to neutrinos with energies ranging from 4.5 MeV to 10 TeV. Atmospheric neutrinos are dominant above 100 MeV for the Super-Kamiokande experiment. In this poster, the neutrino signal correlated with GRB prompt emission was searched for 20 years Super-Kamiokande neutrino observation data, using timing and spatial information.
Gravity's fluctuation derives from its speed—a constant to the absolute space presumed

Subjects: gravity fluctuation, gravitational field, gravitational constant

description: According to the preprint by the same author, "1887 Michelson-Morley experiment: a new analysis with computer assistance" (https://doi.org/10.5281/zenodo.7385914), the M-M experiment should be concluded as delivering no result instead of reporting a null result. This means Newton's conception of absolute space may still be a valid proposal for future experimental tests. With this recognition of the M-M experiment, I combined Einstein's idea of finite speed gravity with Newton's conception of absolute space, by which the two meliorated gravity models were established, so that the doctrine of the field theory—“gravity effective only when its field reaches its target by traveling at finite speed” could be applied to each of the said models. Since there should be no reason for real space, or absolute space, making an instantaneous output of gravitational field elongate longer or shorter in certain radial directions than the rest, it is logical that the radial speed of a gravitational field should be definite and consistent with the absolute space. By using this supplementary assumption to the field theory of gravity, the fluctuation of gravity and the meliorated radar wave measurement were mathematically derived, and the elliptical orbits of planets with their changes in precession were tentatively explained.

description: Land-based activities are increasingly acknowledged for their important ongoing and potential contributions to the Paris Agreement’s mitigation target of reaching carbon neutrality in the second half of this century by reducing emissions and increasing removals from the sector, as well as by its capacity to produce biomass to substitute carbon-intensive products. Land use also plays an important role in short- and medium-term mitigation targets set out in countries’ Nationally Determined Contributions (NDCs) and 2030 strategies and plans. At the same time, the land is a critical resource for multiple developmental and environmental objectives, providing food, fodder, fibre, fuel, and a multitude of other goods and ecosystem services that are fundamental to human well-being. Due to its finite nature, land is subject to competition among these different uses and objectives, and mid to long-term planning of land use and enhancing governance is therefore fundamental to ensure socially and environmentally sound arbitrages among them. As ecosystems (managed and unmanaged) are increasingly impacted by climate change, it is therefore needed that mitigation measures are compatible with adaptation measures. Overall, to achieve sustainability in the sector is also necessary the preservation of other ecosystem services and respect for local communities’ rights, which requires a multiscale and fit-for-purpose governance structure. Despite some recent progress, governance structures and plans rarely address the multiple objectives listed above. For the purpose of the paper, the Intergovernmental Panel for Climate Change (IPCC) Agriculture, Forest, and other Land Uses (AFOLU) sector approach will be used. This paper will assess the AFOLU governance instruments beyond the domestic scale to enhance ambition and implementation of NDCs by acting in the sector while integrating environmental and developmental objectives other than mitigation, and point out the barriers and possible solutions to the governance gaps that are identified.
The Hα surface brightness - radius relation: a robust statistical distance indicator for planetary nebulae

description: Measuring the distances to Galactic planetary nebulae (PNe) has been an intractable problem for many decades. We have now established a robust optical statistical distance indicator, the H$α$ surface brightness- radius or S-r relation, which addresses this problem. We developed this relation from a critically evaluated sample of primary calibrating PNe. The robust nature of the method results from our revised calibrating distances with significantly reduced systematic uncertainties, and the recent availability of high-quality data, including updated nebular diameters and integrated H$α$ fluxes. The S-r technique is simple in its application, requiring only an angular size, an integrated Hα flux, and the reddening to the PN. From these quantities, an intrinsic radius is calculated, which when combined with the angular size, yields the distance directly. Furthermore, we have found that optically thick PNe tend to populate the upper bound of the trend, while optically-thin PNe fall along the lower boundary in the S-r plane. This enables sub-trends to be developed which offer even better precision in the determination of distances, as good as 18 per cent in the case of optically-thin, high-excitation PNe. This is significantly better than any previous statistical indicator. We use this technique to create a catalogue of statistical distances for over 1100 Galactic PNe, the largest such compilation in the literature to date. Finally, in an appendix, we investigate both a set of transitional PNe and a range of PN mimics in the S-r plane, to demonstrate its use as a diagnostic tool. Interestingly, stellar ejecta around massive stars plot on a tight locus in S-r space with the potential to act as a separate distance indicator for these objects.

description: This paper is about the mechanical design of superconducting accelerator magnets. First, we give a brief review of the basic concepts and terms. In the following sections, we describe the particularities of the mechanical design of different types of superconducting accelerator magnets: solenoids, cos-theta, superferric, and toroids. Special attention is given to the pre-stress principle, which aims to avoid the appearance of tensile stresses in the superconducting coils. A case study on a compact superconducting cyclotron summarizes the main steps and the guidelines that should be followed for a proper mechanical design. Finally, we present some remarks on the measurement techniques.

description: The dearth of women leaders in fields such as politics, education, business, et al., has been a topic in several essays and studies, wherein the motives of those appointed to assign such leadership roles are questioned, as well as the rationale of those who vote on choices between male and female aspirants. Cited in this paper are some studies that purport to elucidate the perceived differences between men and women, or even male and female children, when it comes to leadership potential. Among these differences are noted characteristics such as physical height, intellectual abilities, and/or emotional qualities. In this study we explore the demographics of voters and how these can possibly explain why women are largely overlooked or even rejected, in particular as political leaders. We question whether people vote heuristically and/or operate under stereotypical perceptions regarding female intellect, and whether demographics such as religion, education, political viewpoints, etc., steer voters away from female contenders for political leadership positions. Central to this paper is the evolutionary perspective that explains why female leadership is slow to catch up to that of men.
Improved Limits on Millicharged Particles Using the ArgoNeuT Experiment at Fermilab

Publisher: name: Zenodo

description: A search for millicharged particles, a simple extension of the standard model, has been performed with the ArgoNeuT detector exposed to the Neutrinos at the Main Injector beam at Fermilab. The ArgoNeuT Liquid Argon Time Projection Chamber detector enables a search for millicharged particles through the detection of visible electron recoils. We search for an event signature with two soft hits (MeV-scale energy depositions) aligned with the upstream target. For an exposure of the detector of $1.0$ $\times$ $10^{20}$ protons on target, one candidate event has been observed, compatible with the expected background. This search is sensitive to millicharged particles with charges between $10^{-3}e$ and $10^{-1}e$ and with masses in the range from $0.1$ GeV to $3$ GeV. This measurement provides leading constraints on millicharged particles in this large unexplored parameter space region.
