description: Small form factor limits physical input space in earable (i.e., ear-mounted wearable) devices. Off-device earable inputs in alternate mid-air and on-skin around-ear interaction spaces using uni-manual gestures can address this input space limitation. Segmenting these alternate interaction spaces to create multiple gesture regions for reusing off-device gestures can expand earable input vocabulary by a large margin. Although prior earable interaction research has explored off-device gesture preferences and recognition techniques in such interaction spaces, supporting gesture reuse over multiple gesture regions needs further exploration. We collected and analyzed 7560 uni-manual gesture motion data from 18 participants to explore earable gesture reuse by segmentation of on-skin and mid-air spaces around the ear. Our results show that gesture performance degrades significantly beyond 3 mid-air and 5 on-skin around-ear gesture regions for different uni-manual gesture classes (e.g., swipe, pinch, tap). We also present qualitative findings on most and least preferred regions (and associated boundaries) by end-users for different uni-manual gesture shapes across both interaction spaces for earable devices. Our results complement earlier elicitation studies and interaction technologies for earables to help expand the gestural input vocabulary and potentially drive future commercialization of such devices.

description: Anderson localization on random regular graphs (RRG) serves as a toy-model of many-body localization (MBL). We explore the transition for ergodicity to localization on RRG with large connectivity $m$. In the analytical part, we focus on the inverse participation ratio of eigenstates and identify several regimes on the ergodic side of the transition -- self-consistent golden rule, golden rule, precritical, and critical -- that the system consecutively goes through when the disorder increases towards the point $W_c$ of the localization transition. We also perform exact-diagonalization numerics as well as a population-dynamics analysis that combines analytical and numerical techniques. Results of all the approaches are in excellent mutual agreement. We further explore the evolution from ergodicity to localization in two models of Fock-space MBL: fermionic and spin quantum dots. Large-connectivity RRG models serve as an approximation for this class of many-body problems; one of our central goals is to better understand the status of this approximation. Our numerical simulations support the conjecture that, in the limit of a large system, there is a sharp ergodicity-to-localization transition in the quantum-dot models. Furthermore, our results are consistent the RRG-like scaling of the critical disorder, $W_c \sim m \ln m$. While in the golden-rule range the behavior of quantum-dot models is in agreement with analytical predictions based on RRG model, substantial deviations occur in the pre-critical regime. Our results indicate that the pre-critical and critical behavior (as well as the numerical coefficient in the formula for $W_c$) in the quantum-dot models may be different from what one would expect from the RRG-like approximation.

description: We reconstruct the star formation history of the Sco-Cen OB association using a novel high-resolution age map of the region. We develop an approach to produce robust ages for Sco-Cen's recently identified 37 stellar clusters using the SigMA algorithm. The Sco-Cen star formation timeline reveals four periods of enhanced star formation activity, or bursts, remarkably separated by about 5 Myr. Of these, the second burst, which occurred about 15 million years ago, is by far the dominant, and most of Sco-Cen's stars and clusters were in place by the end of this burst. The formation of stars and clusters in Sco-Cen is correlated but not linearly, implying that more stars were formed per cluster during the peak of the star formation rate. Most of the clusters that are large enough to have supernova precursors were formed during the 15 Myr period. Star and cluster formation activity has been continuously declining since then. We have clear evidence that Sco-Cen formed from the inside out and contains 100-pc long chains of contiguous clusters exhibiting well-defined age gradients, from massive older clusters to smaller young clusters. These observables suggest an important role for feedback in forming about half of Sco-Cen stars, although follow-up work is needed to quantify this statement. Finally, we confirm that the Upper-Sco age controversy discussed in the literature during the last decades is solved: the nine clusters previously lumped together as Upper-Sco, a benchmark region for planet formation studies, exhibit a wide range of ages from 3 to 19 Myr.

description: Few treatments have been able to effectively manage pediatric irritable bowel syndrome (IBS). Internet-delivered cognitive behavior therapy (Internet-CBT) based on exposure for abdominal symptoms is effective for adult IBS. The objective of this study was to evaluate the efficacy of Internet-CBT based on behavioral exposure for adolescents with IBS. Adolescents with IBS fulfilling the Rome III criteria were randomized to either Internet-CBT or a wait-list control. The Internet-CBT was a 10-week intervention where the main component was exposure to IBS symptoms by reduction of avoidance of abdominal symptoms and instead stepwise provocation of symptoms. The primary outcome was total score on Gastrointestinal Symptoms Rating Scale for IBS (GSRS-IBS). Secondary outcomes included adolescent- and parent-rated quality of life and parent-rated gastrointestinal symptoms. Difference between groups was assessed from pretreatment to posttreatment and the Internet-CBT group was also evaluated at 6 months after treatment completion. A total of 101 adolescents with IBS (13-17 years of age) were included in this study. Dropout rates were low (6%) and all randomized patients were included in intent-to-treat analyses based on mixed effects models. Analyses showed a significant larger pretreatment to posttreatment change on the primary outcome GSRS-IBS (B-6.42, P=0.006, effect size Cohen's d=0.45, 95% confidence interval (0.12, 0.77)) and on almost all secondary outcomes for the Internet-CBT group compared with the control group. After 6 months, the results were stable or significantly improved. Internet-CBT based on exposure exercises for adolescents with IBS can effectively improve gastrointestinal symptoms and quality of life.

description: Topologically stable matters can have a long lifetime, even if thermodynamically costly, when the thermal agitation is sufficiently low. A magnetic skyrmion lattice (SkL) represents a unique form of long-range magnetic order that is topologically stable, and therefore, a long-lived, metastable SkL can form. Experimental observations of the SkL in bulk crystals, however, have mostly been limited to a finite and narrow temperature region in which the SkL is thermodynamically stable; thus, the benefits of the topological stability remain unclear. Here, we report a metastable SkL created by quenching a thermodynamically stable SkL. Hall-resistivity measurements of MnSi reveal that, although the metastable SkL is short-lived at high temperatures, the lifetime becomes prolonged (>> 1 week) at low temperatures. The manipulation of a delicate balance between thermal agitation and the topological stability enables a deterministic creation/annihilation of the metastable SkL by exploiting electric heating and subsequent rapid cooling, thus establishing a facile method to control the formation of a SkL.

description: The paper discusses the possibilities and prospects of a disciplinary search portal for sources and data on the history of education in Switzerland called “Bildungsgeschichte Schweiz” (www.bildungsgeschichte.ch). The open-access and multilingual portal offers a combined full-text and metadata search of historic holdings from different collections and providers. In the context of increasing digitisation and public accessibility of historical materials and the ongoing digital transformation of the humanities, the goal is to create a user-friendly “information space” for researchers and non-researchers alike. The paper focuses on the ideas behind building up this information space and on the possibilities that are given with the application of a search function to a large and diverse data basis. Particular attention is paid to the reuse of research data in the light of current open research data strategies.

description: In two-dimensional statistical physics, correlation functions of the O(N) and Potts models may be written as sums over configurations of non-intersecting loops. We define sums associated to a large class of combinatorial maps (also known as ribbon graphs). We allow disconnected maps, but not maps that include monogons. Given a map with n vertices, we obtain a function of the moduli of the corresponding punctured Riemann surface. Due to the map's combinatorial (rather than topological) nature, that function is single-valued, and we call it an n-point correlation function. We conjecture that in the critical limit, such functions form a basis of solutions of certain conformal bootstrap equations. They include all correlation functions of the O(N) and Potts models, and correlation functions that do not belong to any known model. We test the conjecture by counting solutions of crossing symmetry for four-point functions on the sphere.

description: A significant fraction of cosmological gamma-ray bursts (GRBs) are characterised by a fast rise and exponential decay (FRED) temporal structure. This is not a distinctive feature of this class, since it is observed in many Galactic transients and is likely descriptive of a sudden release of energy followed by a diffusion process. Possible evidence has recently been reported by Tello et al. (2012) for a Galactic contamination in the sample of FRED GRBs discovered with Swift. We searched for possible Galactic intruders disguised as FRED GRBs in the Swift catalogue up to September 2014. We selected 181 FRED GRBs (2/3 with unknown redshift) and considered different subsamples. We tested the degree of isotropy through the dipole and the quadrupole moment distributions, both with reference to the Galaxy and in a coordinate-system-independent way, as well as with the two-point angular autocovariance function. In addition, we searched for possible indicators of a Galactic origin among the spectral and temporal properties of individual GRBs. We found marginal (~3 sigma) evidence for an excess of FREDs with unknown redshift towards the Galactic plane compared with what is expected for an isotropic distribution corrected for the non-uniform sky exposure. However, when we account for the observational bias against optical follow-up observations of low-Galactic latitude GRBs, the evidence for anisotropy decreases to ~2 sigma. In addition, we found no statistical evidence for different spectral or temporal properties from the bulk of cosmological GRBs. We found marginal evidence for the presence of a disguised Galactic population among Swift GRBs with unknown redshift. The estimated fraction is f=(19 +- 11)%, with an upper limit of 34% (90% confidence).

description: The introduction of more renewable energy sources into the energy system increases the variability and weather dependence of electricity generation. Power system simulations are used to assess the adequacy and reliability of the electricity grid over decades, but often become computational intractable for such long simulation periods with high technical detail. To alleviate this computational burden, we investigate the use of outlier detection algorithms to find periods of extreme renewable energy generation which enables detailed modelling of the performance of power systems under these circumstances. Specifically, we apply the Maximum Divergent Intervals (MDI) algorithm to power generation time series that have been derived from ERA5 historical climate reanalysis covering the period from 1950 through 2019. By applying the MDI algorithm on these time series, we identified intervals of extreme low and high energy production. To determine the outlierness of an interval different divergence measures can be used. Where the cross-entropy measure results in shorter and strongly peaking outliers, the unbiased Kullback-Leibler divergence tends to detect longer and more persistent intervals. These intervals are regarded as potential risks for the electricity grid by domain experts, showcasing the capability of the MDI algorithm to detect critical events in these time series. For the historical period analysed, we found no trend in outlier intensity, or shift and lengthening of the outliers that could be attributed to climate change. By applying MDI on climate model output, power system modellers can investigate the adequacy and possible changes of risk for the current and future electricity grid under a wider range of scenarios.

description: Cosmarium amstelodamense Van Geest et Coesel sp. nov. (Figs. 4, 10, 22)
Diagnosis: Cells 1.2–1.3 times longer than broad, with a moderately deep constriction. Sinus linear, closed for the greater part. Semicells in frontal view subcirculair with a slightly flattened apex. Each semicell with 16, almost equally sized marginal crenations. Cell wall ornamentation consisting of 3–4 concentric series of submarginal rounded verrucae as well as 2–3 irregular, transversal rows of granules or short costae just above the isthmus. In between the submarginal and the supraisthmial ornamentation the cell wall is unsculptured. Cells in lateral view elliptic with a shallow, widely open, median invagination. Semicells in lateral view somewhat ovoid with a slight, basal inflation about 1/3 distance from the median invagination. Semicells in apical view ellipsoid with broadly rounded poles and a slight median inflation. Chloroplast with a single, central pyrenoid. Dimensions: cell length 32–37 μm, cell breadth 23–26μm, cell thickness 18–19μm, breadth of isthmus 12–14μm.
 Type:— THE NETHERLANDS. Amsterdam: rain puddle, 52.38525 N, 4.90167 E, Van Geest, 31 May 2016 (holotype L! Nationaal Herbarium Nederland, Hugo de Vries Lab. no 2018.07, preserved as a fixed natural sample).
Etymology: The name ‘amstelodamense’ is a Latinization of Amsterdam, being our collection area.
 Because of the combination of a crenate cell outline with transversal series of supraisthmial granules, this species should be compared with species such as C. speciosum P. Lundell, C. subspeciosum Nordstedt, C. costatum Nordstedt, C. cinctutum Nordstedt, etc., species of which quite a series of infraspecific taxa have been described. Our alga, readily to be recognized by the regularly wrinkled, subcircular outline of the semicells, could not be matched with any known species in a satisfactory way. All of the above-mentioned taxa are characterized by a semi-elliptic to pyramidal outline of the semicell, not a subcircular one. As our alga was found to be but little variable in shape and occurred in six out of the nine localities sampled (1, 2, 3, 4, 5 and 8), we think it justified to describe it as a new species.

description: Cosmarium scutiforme Van Geest et Coesel sp. nov. (Figs. 7, 18, 24)
Diagnosis: Cells in frontal view elliptic, moderately constricted, about 1.5 times longer than broad, with a shallow, almost closed sinus. Semicells pyramidal with a broadly rounded apex and convex sides. Sides crenate with about 18 crenations that slightly increase in width from the sinus to the apex. On the inner side of the margin there are some two additional series of flattened verrucae visible. The centre of the semicell is distinctly punctate. Lateral view elliptic with a shallow obtusely angled constriction. Apical view elliptic-rhombic. Chloroplast with a single, central pyrenoid. Dimensions: cell length 38–41μm, cell breadth 26–27μm, cell thickness 19–20μm, breadth of isthmus 15–17 μm.
 Type:— THE NETHERLANDS. Amsterdam: rain puddle, 52.33838 N, 4.91980 E, Van Geest, 18 Nov 2015 (holotype L! Nationaal Herbarium Nederland, Hugo de Vries Lab. no 2018.09, preserved as a fixed natural sample).
Etymology: Latin ‘scutu’ means ‘shield’, so ‘scutiforme’ means ‘shield shaped’.
 At first glance, the taxon under discussion reminded us of Cosmarium microsphinctum var. crispulum Nordstedt (Nordstedt & Wittrock 1876) albeit it that the cell apex in our specimens is broader rounded than that in Nordstedt’s (1875, pl. 6: 5) illustration. However, when observing empty cells, some faintly developed series of submarginal verrucae could be distinguished where C. microsphinctum Nordstedt (1876) is characterized by smooth-walled cells. In respect of that, there is more similarity with C. speciosum var. simplex Nordstedt (1872: 31, pl. 6: 12). Main difference is in the outline of the semicell: semi-elliptic in C. speciosum var. simplex, pyramidal in our alga under discussion. Later on, however, various formae of C. speciosum var. simplex have been described varying in cell size, cell outline and number of crenations, see Růžička (1957).
 Our alga could be rendered a place in that series of formae but we are of opinion that it deserves the status of a separate species as it differs in too many aspects with C. speciosum as originally described by Lundell (1871). C. scutiforme was found at location 4 and 5.

description: We provide new methods to straightforwardly obtain compact and analytic expressions for epsilon-expansions of functions appearing in both field and string theory amplitudes. An algebraic method is presented to explicitly solve for recurrence relations connecting different epsilon-orders of a power series solution in epsilon of a differential equation. This strategy generalizes the usual iteration by Picard's method. Our tools are demonstrated for generalized hypergeometric functions. Furthermore, we match the epsilon-expansion of specific generalized hypergeometric functions with the underlying Drinfeld associator with proper Lie algebra and monodromy representations. We also apply our tools for computing epsilon-expansions for solutions to generic first-order Fuchsian equations (Schlesinger system). Finally, we set up our methods to systematically get compact and explicit alpha'-expansions of tree-level superstring amplitudes to any order in alpha'.

description: We introduce local Moufang sets as a generalization of Moufang sets. We present a method to construct local Moufang sets from only one root group and one permutation. We use this to describe $\mathsf{PSL}_2$ over a local ring as a local Moufang set, and give necessary and sufficient conditions for a local Moufang set to be of this form.

description: We show that inflationary models with broken rotational invariance generate testable off-diagonal signatures in the correlation between the $μ$-type distortion and temperature fluctuations of the cosmic microwave background. More precisely, scenarios with a quadrupolar bispectrum asymmetry, usually generated by fluctuations of primordial vector fields, produce a nonvanishing $μ$-$T$ correlation when $|\ell_1-\ell_2|=2$. Since spectral distortions are sensitive to primordial fluctuations up to very small scales, a cosmic variance limited spectral distortion experiment can detect such effects with a high signal-to-noise ratio.

description: Green Internet of Things (IoT) aims to enable a sustainable smart world by making energy efficiency (EE) the main performance indicator for IoT hardware and software. With respect to network design, this implies in developing energy-efficient communication protocols and network architectures adapted to the ubiquitousness of the IoT machine-type devices (MTDs) and the sporadic traffic generated by them, keeping a low power consumption at the MTDs-side. In this sense, reconfigurable intelligent surfaces (RISs) have presented the capacity of significantly improving the network coverage using mostly passive reflecting elements, drastically reducing the power expenditure. In this paper, we develop a realistic power consumption model and an expression for the overall system EE for RIS-aided IoT networks that adopt a two time-scale random access (RA) protocol to handle the uplink transmissions. Specifically, during each time slot of the RA protocol, the RIS covers a specific area of interest in the communication cell with a predefined set of phase-shift configurations, changing the channel qualities of the contending MTDs. Numerical results comparing the RA protocol performance reveal that access policies that exploit information of the channel qualities are suitable for green IoT networks, simultaneously attaining competitive EE and throughput combined with low power consumption at the MTDs-side.

description: In this article, we study the uplink (UL) channel of a cellular network of Internet of Things (IoT) devices assisted by a reconfigurable intelligent surface (RIS) with a limited number of reflecting angle configurations. Firstly, we derive an expression of the required transmit power for the machine-type devices (MTDs) to attain a target signal-to-noise ratio (SNR), considering a channel model that accounts for the RIS discretization into sub-wavelength reflecting elements. Such an expression demonstrates that the transmit power depends on the target SNR, the position of the MTD in the service area, and the RIS setup, which includes the number of reflecting elements and the available reflecting angle configurations. Secondly, we develop an expression for the expected battery lifetime (EBL) of the MTDs, which explicitly depends on the MTD transmit power. Numerical simulations on the energy efficiency (EE) evaluated via the EBL demonstrate the benefits of adopting RISs to enable energy-efficient IoT networks.

description: To explore the origin of the Fermi level pinning in germanium we investigate the Ge(001) and Ge(001):H surfaces. The absence of relevant surface states in the case of Ge(001):H should unpin the surface Fermi level. This is not observed. For samples with donors as majority dopants the surface Fermi level appears close to the top of the valence band regardless of the surface structure. Surprisingly, for the passivated surface it is located below the top of the valence band allowing scanning tunneling microscopy imaging within the band gap. We argue that the well known electronic mechanism behind band bending does not apply and a more complicated scenario involving ionic degrees of freedom is therefore necessary. Experimental techniques involve four point probe electric current measurements, scanning tunneling microscopy and spectroscopy.

Plug, Plan, and Produce for Reconfiguration of Modular and Robot-Based Production Systems

description: Smart Factories, collaborative robots, and cyber-physical systems revolutionize the production processes and reshape the industrial landscape initiated by Industry 4.0 developments. Within this changing environment, the role of the human worker shifts from the manual production of goods to the supervision of automated processes. Workers have to master new skills such as programming collaborative robots, arrange its workspace, and put the workcell into operation.

 As these are new tasks, I introduce a Modular Production System that assists the nonprofessional robotic users with helpful, context-sensitive instructions. To this end, I contribute a methodology I coin “Plug, Plan, and Produce“ that realizes a bidirectional commissioning process with modular components for flexible adjustment of manufacturing processes. An extended Plug-and-Produce concept enables the physical connection of components, wherein the operator explores the workspace utilizing the collaborative robot as an advanced localization tool. During a dedicated planning phase, an interactive user interface facilitates an embedded kinematic simulation to visualize robot motions, to represent the accurate state of workspace, and to compute dynamically collision-free trajectories. Components are specified by a Self-Description to ensure a seamless data-driven integration process providing a distinct function description, an entire representation of robotic task frames, and CAD-models for visualization and collision avoidance purposes of the simulation.

 Targeting the customized and small-batched production with frequent reconfiguration demands, a Skill-Based Architecture allows the configuration, composition, and parameterization of executable workflows to control the robot and production system. Further, I contribute an Interactive Workspace Assistant to generate, simulate, and evaluate component layouts enhancing the assistance of implicit robot programming and commissioning processes.

 I validated the presented methodology against a real-world setup evaluating the robotic system in an extensive user study where participants performed a flexible workcell setup with tasks of increasing complexity. The results support the hypothesis that the interactive assistance supports the commissioning process of users conducting a previously unknown robotic tasks in an industrial assembly scenario.

description: US Hispanic/Latino individuals are diverse in genetic ancestry, culture, and environmental exposures. Here, we characterized and controlled for this diversity in genome-wide association studies (GWASs) for the Hispanic Community Health Study/Study of Latinos (HCHS/SOL). We simultaneously estimated population-structure principal components (PCs) robust to familial relatedness and pairwise kinship coefficients (KCs) robust to population structure, admixture, and Hardy-Weinberg departures. The PCs revealed substantial genetic differentiation within and among six self-identified background groups (Cuban, Dominican, Puerto Rican, Mexican, and Central and South American). To control for variation among groups, we developed a multi-dimensional clustering method to define a “genetic-analysis group” variable that retains many properties of self-identified background while achieving substantially greater genetic homogeneity within groups and including participants with non-specific self-identification. In GWASs of 22 biomedical traits, we used a linear mixed model (LMM) including pairwise empirical KCs to account for familial relatedness, PCs for ancestry, and genetic-analysis groups for additional group-associated effects. Including the genetic-analysis group as a covariate accounted for significant trait variation in 8 of 22 traits, even after we fit 20 PCs. Additionally, genetic-analysis groups had significant heterogeneity of residual variance for 20 of 22 traits, and modeling this heteroscedasticity within the LMM reduced genomic inflation for 19 traits. Furthermore, fitting an LMM that utilized a genetic-analysis group rather than a self-identified background group achieved higher power to detect previously reported associations. We expect that the methods applied here will be useful in other studies with multiple ethnic groups, admixture, and relatedness.

description: Platelets play an essential role in hemostasis and thrombosis. We performed a genome-wide association study of platelet count in 12,491 participants of the Hispanic Community Health Study/Study of Latinos by using a mixed-model method that accounts for admixture and family relationships. We discovered and replicated associations with five genes (ACTN1, ETV7, GABBR1-MOG, MEF2C, and ZBTB9-BAK1). Our strongest association was with Amerindian-specific variant rs117672662 (p value = 1.16 × 10−28) in ACTN1, a gene implicated in congenital macrothrombocytopenia. rs117672662 exhibited allelic differences in transcriptional activity and protein binding in hematopoietic cells. Our results underscore the value of diverse populations to extend insights into the allelic architecture of complex traits.

description: We investigate the evolution of the galaxy two point correlation function (CF) over a wide redshift range, 0.2 < z < 3. For the first time the systematic analysis covers the redshifts above 1 - 1.5. The catalogue of ~250000 galaxies with i+ < 25 and known photometric redshifts in the Subaru Deep field is used. The galaxies are divided into three luminosity classes and several distance/redshift bins. First, the 2D CF is determined for each luminosity class and distance bin. Calculations are based on the quantitative differences between the surface distributions of galaxy pairs with comparable and distinctly different photometric redshifts. The power law approximation for the CF is used. A limited accuracy of photometric redshifts as compared to the spectroscopic ones has been examined and taken into account. Then, the 3D functions for all the selected luminosities and distances are calculated. The power-law parameters of the CF, the slope and the correlation length, are determined. Both parameters do not show strong variations over the whole investigated redshift range. The slope of the luminous galaxies appears to be consistently steeper than that for the fainter ones. The linear bias factor, b(z), grows systematically with redshift; assuming the local normalization b(0) = 1.1-1.2, the bias reaches 3 - 3.5 at the high redshift limit.

description: Approximate Bayesian Computation (ABC) methods are used to approximate posterior distributions in models with unknown or computationally intractable likelihoods. Both the accuracy and computational efficiency of ABC depend on the choice of summary statistic, but outside of special cases where the optimal summary statistics are known, it is unclear which guiding principles can be used to construct effective summary statistics. In this paper we explore the possibility of automating the process of constructing summary statistics by training deep neural networks to predict the parameters from artificially generated data: the resulting summary statistics are approximately posterior means of the parameters. With minimal model-specific tuning, our method constructs summary statistics for the Ising model and the moving-average model, which match or exceed theoretically-motivated summary statistics in terms of the accuracies of the resulting posteriors.
