description: We compare the peak optical luminosity with the orbital period for a sample of 22 stellar-mass black hole candidates with good measurements of both quantities. We find that the peak absolute magnitude for the outbursts follows a linear relation with $M_{V,peak}=3.48 (\pm 0.85)-3.89 (\pm 0.91) {\rm log}P_{orb}$, which corresponds to a $L_V \propto P_{orb}^{1.56\pm 0.36}$ power law relation. Excluding V4641 Sgr which is a strong outlier and not likely to have outbursts produced by the standard disc instability model, in addition to BW Cir and V821 Ara -- both of which have highly uncertain distances; the new correlation for the 19 sources is found to be $M_{V,peak}= 3.01\;(\pm 0.93)-3.21\;(\pm 1.04){\rm log}P_{orb}$, which corresponds to $L_V \propto P_{orb}^{1.28 \pm 0.42}$. This is an analogous relationship to the "Warner relation" between orbital period and peak luminosity found for cataclysmic variables. We discuss the implications of these results for finding black hole X-ray binaries in other galaxies and in our own Galaxy with the Large Synoptic Survey Telescope and other future large time domain surveys.

description: Most generic object detectors are mainly built for standard object detection tasks such as COCO and PASCAL VOC. They might not work well and/or efficiently on tasks of other domains consisting of images that are visually different from standard datasets. To this end, many advances have been focused on adapting a general-purposed object detector with limited domain-specific designs. However, designing a successful task-specific detector requires extraneous manual experiments and parameter tuning through trial and error. In this paper, we first propose and examine a fully-automatic pipeline to design a fully-specialized detector (FSD) which mainly incorporates a neural-architectural-searched model by exploring ideal network structures over the backbone and task-specific head. On the DeepLesion dataset, extensive results show that FSD can achieve 3.1 mAP gain while using approximately 40% fewer parameters on binary lesion detection task and improved the mAP by around 10% on multi-type lesion detection task via our region-aware graph modeling compared with existing general-purposed medical lesion detection networks.

description: The coronal magnetic field is the prime driver behind many as-yet unsolved mysteries: solar eruptions, coronal heating, and the solar wind, to name a few. It is, however, still poorly observed and understood. We highlight key questions related to magnetic energy storage, release, and transport in the solar corona, and their relationship to these important problems. We advocate for new and multi-point co-optimized measurements, sensitive to magnetic field and other plasma parameters, spanning from optical to $γ$-ray wavelengths, to bring closure to these long-standing and fundamental questions. We discuss how our approach can fully describe the 3D magnetic field, embedded plasma, particle energization, and their joint evolution to achieve these objectives.

description: With the human friendly declarative intent policy expression, intent-driven network can make network management and configuration autonomous without human intervention. However, the availability and dependability of these refined policies from the expressed intents should be well ensured by full-life cycle verification. Moreover, intent-driven network verification is still in its initial stage, and there is a lack of full-life cycle end-to-end verification framework. As a result, in this article, we present and review existing verification techniques, and classify them according to objective, purpose, and feedback. Furthermore, we describe intent verification as a technology that provides assurance during the intent form conversion process and propose a novel full-life cycle verification framework that expands on the concept of traditional network verification. Finally, we verify the feasibility and validity of the presented verification framework in the case of an access control policy for different network functions with multi conflict intents.

La rilevanza giuridica delle unioni omosessuali nell’antica Roma

description: Oggetto del presente lavoro di ricerca è lo studio circa l’eventuale rilevanza giuridica delle unioni omosessuali nell’antica Roma. Dedicarsi al delicato tema dell’omosessualità dalla prospettiva giuridica costituisce di per sé un’esperienza di studio complessa, la quale – nelle sue innumerevoli articolazioni ed implicazioni – valica i limiti spazio-temporali tipici del perimetro di ricerca degli storici del diritto, tanto da sollecitare anche l’attenzione dei vigentisti i quali tutt’oggi, a cavallo fra diritto, morale e politica, copiosamente ne dibattono. Pensare all’omosessualità come una variante naturale del comportamento umano, piuttosto che una sua aberrazione o una trasgressione, costituisce un imprescindibile punto di partenza che (senza violare la pur sempre legittima opinione personale sul punto) consente allo storico del diritto di avvicinarsi alla questione con un atteggiamento più ricettivo ai segnali – non numerosi e non sempre facilmente decodificabili – presenti nelle fonti oggi disponibili al suo vaglio, la maggior parte delle quali posteriori al I sec. a.C.. Come si osserva nel lavoro, la posizione – in linea di massima – degli antichi Romani rispetto all’omosessualità era di parziale ‘indifferenza morale’, almeno fintantoché alcuni suoi palesamenti non confliggessero con altri valori sociali di primario rilievo: i Romani, insomma, non erano abituati a classificare l’orientamento sessuale di un civis in maniera granitica (adoperando, dunque, termini assimilabili agli odierni ‘omosessuale’, ‘bisessuale’, ‘eterosessuale’, ‘pansessuale’, etc.), quanto piuttosto ad osservarne la condotta complessiva al fine di considerarlo pudicus o inpudicus. La premessa testé segnata, tuttavia, merita di essere ulteriormente approfondita: è necessario chiarire quali fossero le logiche (anche etiche e sociali) sottese a siffatto atteggiamento e quali ne fossero le conseguenze sul piano giuridico. Pertanto, premessi doverosi cenni al valore della pudicitia ed al rapporto intercorrente fra essa e gli atteggiamenti omosessuali, si procederà a verificare se, nelle varie epoche della storia di Roma, esistessero configurazioni del rapporto fra persone dello stesso sesso assimilabili alle odierne unioni civili o matrimoni. La parte conclusiva dello studio, invece, è orientata ad esaminare l’approccio del Cristianesimo alle relazioni omosessuali, quali furono i principali provvedimenti assunti per contrastarle, nonché, infine, si passerà allo studio circa l’effettiva portata del loro contenuto, convenzionalmente ritenuto come ineluttabilmente proibitivo e repressivo.

description: In a calculation of rotated matrix elements with angular momentum projection, the generalized Wick's theorem may encounter a practical problem of combinatorial complexity when the configurations have more than four quasi-particles (qps). The problem can be solved by employing the Pfaffian algorithm generally applicable to calculations of matrix elements for Hartree-Fock-Bogoliubov states with any number of qps. This breakthrough in many-body techniques enables studies of high-spin states in a shell-model framework. As the first application of the Pfaffian algorithm, the configuration space of the Projected Shell Model is expanded to include 6-qp states for both positive and negative parities. Taking $^{166}$Hf as an example, we show that 6-qp states become the main configuration of the yrast band beyond spin $I \approx 34\hbar$, which explains the observed third back-bending in moment of inertia. Structures of multi-qp high-$K$ isomers in $^{176}$Hf are analyzed as another example.

description: Handheld kinesthetic haptic interfaces can provide greater mobility and richer tactile information as compared to traditional grounded devices. In this paper, we introduce a new handheld haptic interface which takes input using bidirectional coupled finger flexion. We present the device design motivation and design details and experimentally evaluate its performance in terms of transparency and rendering bandwidth using a handheld prototype device. In addition, we assess the device's functional performance through a user study comparing the proposed device to a commonly used grounded input device in a set of targeting and tracking tasks.

description: The emission from young stellar objects (YSOs) in the mid-IR is dominated by the inner rim of their circumstellar disks. We present an IR-monitoring survey of about 800 objects in the direction of the Lynds 1688 (L1688) star forming region over four visibility windows spanning 1.6 years using the \emph{Spitzer} space telescope in its warm mission phase. Among all lightcurves, 57 sources are cluster members identified based on their spectral-energy distribution and X-ray emission. Almost all cluster members show significant variability. The amplitude of the variability is larger in more embedded YSOs. Ten out of 57 cluster members have periodic variations in the lightcurves with periods typically between three and seven days, but even for those sources, significant variability in addition to the periodic signal can be seen. No period is stable over 1.6 years. Non-periodic lightcurves often still show a preferred timescale of variability which is longer for more embedded sources. About half of all sources exhibit redder colors in a fainter state. This is compatible with time-variable absorption towards the YSO. The other half becomes bluer when fainter. These colors can only be explained with significant changes in the structure of the inner disk. No relation between mid-IR variability and stellar effective temperature or X-ray spectrum is found.

description: Dengue fever is a virulent disease spreading over 100 tropical and subtropical countries in Africa, the Americas, and Asia. This arboviral disease affects around 400 million people globally, severely distressing the healthcare systems. The unavailability of a specific drug and ready-to-use vaccine makes the situation worse. Hence, policymakers must rely on early warning systems to control intervention-related decisions. Forecasts routinely provide critical information for dangerous epidemic events. However, the available forecasting models (e.g., weather-driven mechanistic, statistical time series, and machine learning models) lack a clear understanding of different components to improve prediction accuracy and often provide unstable and unreliable forecasts. This study proposes an ensemble wavelet neural network with exogenous factor(s) (XEWNet) model that can produce reliable estimates for dengue outbreak prediction for three geographical regions, namely San Juan, Iquitos, and Ahmedabad. The proposed XEWNet model is flexible and can easily incorporate exogenous climate variable(s) confirmed by statistical causality tests in its scalable framework. The proposed model is an integrated approach that uses wavelet transformation into an ensemble neural network framework that helps in generating more reliable long-term forecasts. The proposed XEWNet allows complex non-linear relationships between the dengue incidence cases and rainfall; however, mathematically interpretable, fast in execution, and easily comprehensible. The proposal's competitiveness is measured using computational experiments based on various statistical metrics and several statistical comparison tests. In comparison with statistical, machine learning, and deep learning methods, our proposed XEWNet performs better in 75% of the cases for short-term and long-term forecasting of dengue incidence.

description: We present a simple and general coherence model for multiorbital tunnel ionization of molecules, which we incorporate into our previously developed density matrix approach for sequential double ionization [Yuen and Lin, Phys. Rev. A 106, 023120 (2022)]. The influence of this coherence is investigated through simulations of single ionization and sequential double ionization of N$_2$ and O$_2$ using few-cycle near-infrared laser pulses. In the case of single ionization, our results reveal the crucial role played by this coherence in generating population inversion in N$_2^+$, suggesting a potential mechanism for air lasing. Regarding sequential double ionization, we observe only minor changes in the kinetic energy release spectra when the coherence is included, while noticeable differences in the angle-dependent dication yield for both N$_2$ and O$_2$ are found. Based on these findings, we recommend the inclusion of multiorbital tunnel ionization coherence in models for single ionization of general molecules, while suggesting that it can be safely neglected in the case of sequential double ionization.

description: We reviewed the tree architecture models for a deeper understanding of plant forms and their suitability in a wide range of natural environments. Few classical papers were analysed to see the relationship of tree architecture with the successional status that implies distinct strategies for early to late-successional species. Canopy architecture has always been important with respect to forest characteristics such as species composition and crown closure. Remote sensing plays a crucial role in providing cost-effective and timely information for the measurement of forest or individual tree growth factors and also provides information regarding ecological and environmental processes. The attention of researchers has also been drawn towards automated detection and delineation of individual tree crowns from high-resolution remotely sensed imagery techniques. In this study, we depicted that several algorithms and image-processing techniques are required to improve the accuracy of plant canopy architecture.
Advances in Shell Buckling: Theory and Experiments

description: In a recent feature article in this journal, co-authored by Gert van der Heijden, I described the static-dynamic analogy and its role in understanding the localized post-buckling of shell-like structures, looking exclusively at integrable systems. We showed the true significance of the Maxwell energy criterion load in predicting the sudden onset of 'shock sensitivity' to lateral disturbances. The present paper extends the survey to cover non-integrable systems, such as thin compressed shells. These exhibit spatial chaos, generating a multiplicity of localized paths (and escape routes) with complex snaking and laddering phenomena. The final theoretical contribution shows how these concepts relate to the response and energy barriers of an axially compressed cylindrical shell. After surveying NASA's current shell-testing programme, a new non-destructive technique is proposed to estimate the 'shock sensitivity' of a laboratory specimen that is in a compressed meta-stable state before buckling. A probe is used to measure the nonlinear load-deflection characteristic under a rigidly applied lateral displacement. Sensing the passive resisting force, it can be plotted in real time against the displacement, displaying an equilibrium path along which the force rises to a maximum and then decreases to zero: having reached the free state of the shell that forms a mountain-pass in the potential energy. The area under this graph gives the energy barrier against lateral shocks. The test is repeated at different levels of the overall compression. If a symmetry-breaking bifurcation is encountered on the path, computer simulations show how this can be supressed by a controlled secondary probe tuned to deliver zero force on the shell.

Spin-orbit coupling, strong correlation, and insulator-metal transitions: the J$_{\rm eff}$ =3\2 ferromagnetic Mott insulator Ba$_{2}$NaOsO$_{6}$

description: The double perovskite Ba$_{2}$NaOsO$_{6}$ (BNOO), an exotic example of a very high oxidation state (heptavalent) osmium $d^1$ compound and also uncommon by being a ferromagnetic Mott insulator without Jahn-Teller (JT) distortion, is modeled using the density functional theory (DFT) hybrid functional based exact exchange for correlated electrons (oeeHyb) method and including spin-orbit coupling (SOC). The experimentally observed narrow gap ferromagnetic insulating ground state is obtained, with easy axis along [110] in accord with experiment, providing support that this approach provides a realistic method for studying this system. The predicted spin density for [110] spin orientation is nearly cubic (unlike for other directions), providing an explanation for the absence of JT distortion. An orbital moment of -0.4$μ_B$ strongly compensates the +0.5$μ_B$ spin moment on Os, leaving a strongly compensated moment more in line with experiment. Remarkably, the net moment lies primarily on the oxygen ions. An insulator-metal transition by rotating the magnetization direction with an external field under moderate pressure is predicted as one consequence of strong SOC, and metallization under moderate pressure is predicted. Comparison is made with the isostructural, isovalent insulator Ba$_2$LiOsO$_6$ which however orders antiferromagnetically.

description: We explore the abilities of two machine learning approaches for no-arbitrage interpolation of European vanilla option prices, which jointly yield the corresponding local volatility surface: a finite dimensional Gaussian process (GP) regression approach under no-arbitrage constraints based on prices, and a neural net (NN) approach with penalization of arbitrages based on implied volatilities. We demonstrate the performance of these approaches relative to the SSVI industry standard. The GP approach is proven arbitrage-free, whereas arbitrages are only penalized under the SSVI and NN approaches. The GP approach obtains the best out-of-sample calibration error and provides uncertainty quantification.The NN approach yields a smoother local volatility and a better backtesting performance, as its training criterion incorporates a local volatility regularization term.

description: In a sample of 60 quasars selected from Sloan Digital Sky Survey (SDSS) with at least six-epoch spectroscopy, we investigate the variability of emission lines and continuum luminosity at various aspects. A strong anti-correlation between the variability and continuum luminosity at 2500 Å is found for the sample, which is consistent with previous works. In individual sources, we find that half of the sample objects have a trend of being bluer-when-brighter trend (BWB), while the remaining half exhibit redder-when-brighter trend (RWB). Although the mechanism for RWB is unclear, the effects of host galaxy contribution due to seeing variations can not be completely ruled out. As expected from photoionization model, the positive correlations between the broad emission line and continuum luminosity are found in most individual sources, as well as for the whole sample. We confirm the Baldwin effect in most individual objects and the whole sample, while a negative Baldwin effect is also found in several quasars, which can be at least partly (if not all) due to the host galaxy contamination. We find positive correlations between the broad emission line luminosity and line width in most individual quasars, as well as the whole sample, implying a more variable line base than the line core.

description: In the last years, epigenetics and functional genomics methods to evaluate the genomic effects and mechanisms of mind-body therapies have increasingly grown. DNA microarray technology has been used to show the involvement of the stress response pathways both in the case of disease and stress and as an effect of mind-body therapies. In the present research, the DNA samples obtained from 20 individuals who experienced a mind-body therapeutic protocol (MBT-T), were analysed from the bio-molecular point of view by means of an epigenetic marker (MSAP molecular tool), in order to estimate the different status of methylation. The subjects were compared at 3 different times: prior to, 1 hour after, and 24 hours after the treatment. The molecular data were processed through different biostatistics approaches: the Bayesian statistics approach, in order to estimate the clustering membership of the subjects (Structure), and the statistical estimation of the DNA methylation level (MSAP statistical tool). The structure analysis revealed that the clusters and their membership changed among the three time points moving from higher heterogeneous distribution to higher homogeneous clusters. Before the treatment, the subjects’ epigenetic profiles were heterogeneous; after the mind-body treatment we found that epigenetic profiles converged to homogeneous DNA methylation status. DNA epigenetic status of the subjects was affected by the MBT-T treatment.

description: We have established a network of 19 faint (16.5 mag $< V < $19 mag) northern and equatorial DA white dwarfs as spectrophotometric standards for present and future wide-field observatories. Our analysis infers SED models for the stars that are tied to the three CALSPEC primary standards. Our SED models are consistent with panchromatic Hubble Space Telescope ($HST$) photometry to better than 1%. The excellent agreement between observations and models validates the use of non-local-thermodynamic-equilibrium (NLTE) DA white dwarf atmospheres extinguished by interstellar dust as accurate spectrophotometric references. Our standards are accessible from both hemispheres and suitable for ground and space-based observatories covering the ultraviolet to the near infrared. The high-precision of these faint sources make our network of standards ideally suited for any experiment that has very stringent requirements on flux calibration, such as studies of dark energy using the Large Synoptic Survey Telescope (LSST) and the Wide-Field Infrared Survey Telescope ($WFIRST$).

description: Purpose: Access to communication is a basic human right, yet autistic adults have reported challenges fully and effectively expressing themselves throughout childhood. This may be due to the historical (and ongoing) focus and prioritization of speech skills as a barometer of communicative success. The result is a lack of support for other forms of communication for children who may speak but still require support to fully meet their communication needs. This study aimed to examine the knowledge, experience, and training of school-based professionals in order to better understand one possible barrier to early communication access for autistic children.Method: Using a participatory research method, we designed and administered a 35-question online survey. A total of 567 participants completed the survey, including 465 special educators, 71 speech-language pathologists (SLPs), and 31 other professionals. A segment of the survey data was analyzed in R. Comparisons between and within the largest groups (SLPs and special educators) were made with nonparametric statistics, including Fisher’s exact, Wilcoxon signed-ranks, and Quade tests.Results: SLPs and special educators differed significantly on a variety of survey measures, including undergraduate coursework in augmentative and alternative communication (AAC) and autism, caseloads, and confidence related to working with autistic students and AAC users. Regardless of profession, most respondents reported completing what they considered to be an AAC assessment.Conclusions: Increasing school-based professionals’ knowledge related to autism and AAC, as well as opportunities to improve skills, is critical to resolving access and opportunity barriers for autistic children who speak but may benefit from AAC. Partnering with autistic people to better understand autistic speech and careful collaboration among team members are recommended.Supplemental Material S1. Participant survey.Donaldson, A.

description: Abstract Electric power summarizes different kinds of utilities and interests considered to be a responsibility of the State, of the person and of the market, taking into account that “not only the functioning of economy but above all of the institutions and of the basic public services and even the survival of people” depend on the security of energy supply. The energy sector has undergone a far-reaching process of privatization and liberalization which has demolished the organization structure provided for by article 43 of the Italian Constitution (public monopoly and vertically integrated undertaking) for the benefit of the market as a result of (alleged) advantages in terms of the efficient allocation of resources. Finally, the use of electricity meets existential interests to the point that it is a real need. In fact, several parties have claimed that the right of access to basic energy services should be elevated to fundamental human right. The specific characteristics of electric power – in other words the fact that it serves a multiplicity of interests –inevitably influence the legal classification of the resource and the related owner statute. Authoritative legal theory explain that the legal basis of the service lie not so much on the possibility of economic exploitation but on the suitability to become an objective reference point of (economic or existential) interests deserving legal protection. In this perspective, the question is whether electricity can be considered as a common good. However, in the present case, the selection of specific characteristics is not sufficient to solve the problem of the objectification sub specie iuris. This is mainly due to the fact that the concept of energy is unclear because “even if the term is generally understood, actually it includes a variety of events and situations which cannot be reduced to an unique ensemble”. In this respect, it should be noted right from the start that electrical current is the result of a multi-stage system and that each stage is regulated by specific laws and has its own legal status.

description: We associate lattices to the sets of unions and intersections of left and right quotients of a regular language. For both unions and intersections, we show that the lattices we produce using left and right quotients are dual to each other. We also give necessary and sufficient conditions for these lattices to have maximal possible complexity.

description: Focal Ration Degradation (FRD) is a change in light angular distribution caused by fiber optics. FRD is important to fiber-fed, spectroscopic astronomical systems because it can cause loss of signal, degradation in spectral resolution, or increased complexity in spectrograph design. Laboratório Nacional de Astrofísica (LNA) has developed a system that can accurately and precisely measures FRD, using an absolute method that can also measure fiber throughput. This paper describes the metrology system and shows measurements of Polymicro fiber FBP129168190, FBP127165190 and Fujikura fiber 128170190. Although the FRD of the two fibers are low and similar to one another, it is very important to know the exact characteristics of these fibers since both will be used in the construction of FOCCoS (Fiber Optical Cable and Connectors System) for PFS (Prime Focus Spectrograph) to be installed at the Subaru telescope.

description: Equilibrium atomic configuration and electronic structure of the (001) surface of IV-VI semiconductors PbTe, PbSe, SnTe and SnSe, is studied using the density functional theory (DFT) methods. At surfaces of all those compounds, the displacements of ions from their perfect lattice sites reveal two features characteristic of the rock salt crystals. First, the ionic displacements occur only along the direction perpendicular to the surface, and they exhibit the rumpling effect, i.e., the vertical shifts of cations and anions differ. Second, the interlayer spacing of the first few monolayers at the surface oscillates. Our results are in good agreement with the previous X-ray experimental data and theoretical results where available. They also are consistent with the presence of two {110} mirror planes at the (001) surface of the rock salt. One the other hand, experiments preformed for the topological Pb$_{1-x}$Sn$_x$ Se alloy indicate breaking of the mirror symmetry due to a large 0.3 Å relative displacement of the cation and anion sublattices at the surface, which induces the opening of the gap of the Dirac cones. Our results for Pb$_{1-x}$Sn$_x$Se including the simulated STM images, are in contradiction with these findings, since surface reconstructions with broken symmetry are never the ground state configurations. The impact of the theoretically determined surface configurations and of the chemical disorder on the surface states is analyzed.

description: Course load analytics (CLA) inferred from LMS and enrollment features can offer a more accurate representation of course workload to students than credit hours and potentially aid in their course selection decisions. In this study, we produce and evaluate the first machine-learned predictions of student course load ratings and generalize our model to the full 10,000 course catalog of a large public university. We then retrospectively analyze longitudinal differences in the semester load of student course selections throughout their degree. CLA by semester shows that a student's first semester at the university is among their highest load semesters, as opposed to a credit hour-based analysis, which would indicate it is among their lowest. Investigating what role predicted course load may play in program retention, we find that students who maintain a semester load that is low as measured by credit hours but high as measured by CLA are more likely to leave their program of study. This discrepancy in course load is particularly pertinent in STEM and associated with high prerequisite courses. Our findings have implications for academic advising, institutional handling of the freshman experience, and student-facing analytics to help students better plan, anticipate, and prepare for their selected courses.

description: The enhancing waste productions, the change in its composition along with the widespread awareness of environmental issues have increased the technical interest towards the implementation of suitable waste management strategies. Aim of these strategies is the minimization of waste amount and hazardousness as well as the identification of correct treatment and disposal systems, reducing the environmental impact and enhancing the recovery of materials and energy. The implementation of an integrated waste management system represents the most suitable option to enhance waste recovery, thus reducing landfill disposal. In this context, the characterization of the materials subjected to recovery activities is a fundamental phase, because of the potential health and environmental risk connected to the reintroduction, in the cycle of matter, of waste substances, which are potentially harmful. Into consideration of these problems, the research was aimed at: identifying innovative methods for material recovery from waste; studying and promoting the implementation of the most appropriate characterization procedures, in order to minimize the risk associated with the products of recovery activities. According to the different characteristics of waste, the experimental activity was carried out with reference to two different matrixes: a source sorted cellulosic material; an organic fraction coming from the mechanical selection of unsorted waste. The identification of non-conventional recovery solutions is, indeed, particularly interesting, for both cellulosic material and mechanically sorted organic waste. In the former case, the reason is related to the uncertain prospects of the pulp market, so that its use for litter production was proposed. On the other hand, the possible use of the mechanically selected organic fraction represents one of the most important issues due to the its high content of impurities, which limits its recovery. For this matrix, the use as landfill daily cover material was proposed. [edited by Author]

description: Diversity, equity and inclusion (DEI) programs can only be implemented successfully if proper work-life balance is possible in Heliophysics (and in STEM field in general). One of the core issues stems from the culture of "work-above-life" associated with mission concepts, development, and implementation but also the expectations that seem to originate from numerous announcements from NASA (and other agencies). The benefits of work-life balance are well documented; however, the entire system surrounding research in Heliophysics hinders or discourages proper work-life balance. For example, there does not seem to be attention paid by NASA Headquarters (HQ) on the timing of their announcements regarding how it will be perceived by researchers, and how the timing may promote a culture where work trumps personal life. The same is true for remarks by NASA HQ program officers during panels or informal discussions, where seemingly innocuous comments may give a perception that work is expected after "normal" work hours. In addition, we are calling for work-life balance plans and implementation to be one of the criteria used for down-selection and confirmation of missions (Key Decision Points: KDP-B, KDP-C).

description: We use Superconducting QUantum Interference Device (SQUID) microscopy to characterize the current-phase relation (CPR) of Josephson Junctions from 3-dimentional topological insulator HgTe (3D-HgTe). We find clear skewness in the CPRs of HgTe junctions ranging in length from 200 nm to 600 nm. The skewness indicates that the Josephson current is predominantly carried by Andreev bound states with high transmittance, and the fact that the skewness persists in junctions that are longer than the mean free path suggests that the effect may be related to the helical nature of the Andreev bound states in the surface of HgTe.
