description: A novel prediction is derived by the Two-State-Vector-Formalism (TSVF) for a particle superposed over three boxes. Under appropriate pre- and postselections, and with tunneling enabled between two of the boxes, it is possible to derive not only one, but three predictions for three different times within the intermediate interval. These predictions are moreover contradictory. The particle (when looked for using a projective measurement) seems to disappear from the first box where it would have been previously found with certainty, appearing instead within the third box, to which no tunneling is possible, and later re-appearing within the second. It turns out that local measurement (i.e. opening one of the boxes) fails to indicate the particle's presence, but subtler measurements performed on the two boxes together reveal the particle's nonlocal modular momentum spatially separated from its mass. Another advance of this setting is that, unlike other predictions of the TSVF that rely on weak and/or counterfactual measurements, the present one uses actual projective measurements. This outcome is then corroborated by adding weak measurements and the Aharonov-Bohm effect. The results strengthen the recently suggested time-symmetric Heisenberg ontology based on nonlocal deterministic operators. They can be also tested using the newly developed quantum router.

description: Sub-Neptune planets formed in the protoplanetary disk accreted hydrogen-helium (H,He) envelopes. Planet formation models of sub-Neptunes formed by pebble accretion result in small rocky cores surrounded by polluted H,He envelopes where most of the rock (silicate) is in vapor form at the end of the formation phase. This vapor is expected to condense and rain-out as the planet cools. In this Letter we examine the timescale for the rainout and its effect on the thermal evolution. We calculate the thermal and structural evolution of a 10 Earth masses planet formed by pebble accretion, taking into account material redistribution from silicate rainout (condensation and settling) and from convective mixing. We find that the duration of the rainout in sub-Neptunes is on Gyr timescale and varies with envelope mass: planets with envelopes below 0.75 Earth mass rainout into a core-envelope structure in less than 1 Gyr, while planets in excess of 0.75 Earth mass of H,He preserve some of their envelope pollution for billions of years. The energy released by the rainout inflates the radius with respect to planets that start out from a plain core-envelope structure. This inflation would result in estimates of the H,He contents of observed exoplanets based on the standard core-envelope structure to be too high.We identify a number of planets in the exoplanet census where rainout may operate, which would result in their H,He contents to be overestimated by up to a factor two. Future accurate age measurements by the PLATO mission may allow the identification of planets formed with polluted envelopes.

description: This review comprehensively covers the coordination chemistry of elemental phosphorus during the years 2011–2020. The main part is dedicated to the activation of white phosphorus mediated by early and late transition metals and its subsequent reactivity once in the coordination sphere of a metal. The burgeoning interest towards early TMs has opened the way to new coordination topologies and types of reactivity. Meanwhile, the coordination chemistry of P₄ towards late transition metal elements has also attracted significant attention. Numerous studies have targeted transformations of P₄-derived phosphorus ligands and the subsequent release of said ligand fragments. The final part of this review focuses on the black allotrope of phosphorus, which offers a polydentate phosphorus surface able to interact with transition metals forming new functionalized 2D materials.

description: FRB 20210912A is a fast radio burst (FRB), detected and localised to sub-arcsecond precision by the Australian Square Kilometre Array Pathfinder. No host galaxy has been identified for this burst despite the high precision of its localisation and deep optical and infrared follow-up, to 5-$σ$ limits of $R=26.7$ mag and $K_\mathrm{s}=24.9$ mag with the Very Large Telescope. The combination of precise radio localisation and deep optical imaging has almost always resulted in the secure identification of a host galaxy, and this is the first case in which the line-of-sight is not obscured by the Galactic disk. The dispersion measure of this burst, $\mathrm{DM_{FRB}}=1233.696\pm0.006~\mathrm{pc}\ \mathrm{cm}^{-3}$, allows for a large source redshift of $z>1$ according to the Macquart relation. It could thus be that the host galaxy is consistent with the known population of FRB hosts, but is too distant to detect in our observations ($z>0.7$ for a host like that of the first repeating FRB source, FRB 20121102A); that it is more nearby with a significant excess in $\mathrm{DM_{host}}$, and thus dimmer than any known FRB host; or, least likely, that the FRB is truly hostless. We consider each possibility, making use of the population of known FRB hosts to frame each scenario. The fact of the missing host has ramifications for the FRB field: even with high-precision localisation and deep follow-up, some FRB hosts may be difficult to detect, with more distant hosts being the less likely to be found. This has implications for FRB cosmology, in which high-redshift detections are valuable.

description: The increasing demand for the use of lightweight materials and part designs, especially in the automotive industry, is a driving factor for the development of new joining techniques. One of the main challenges is joining of dissimilar materials. Magnetic pulse welding (MPW), a high-velocity, cold forming technique is a possible solution, as it is known for its ability to join dissimilar metals. To determine the potential of this technology for a certain application, simulation techniques have become a major part of the research process. This paper shows some ways how to use simulation tools effectively to analyse the coil and the field shaper-geometry as well as to study their effect on the workpiece. The predictability of current distributions, resulting magnetic pressures and general process efficiency are discussed. Furthermore it is described which simplifications may be applied in order to reduce the simulation time for transient calculations. Especially aspects of the transient force evolution during a pulse are discussed and comparisons to simplified timeharmonic results are given.

description: While the vast majority of multiple-planet systems have their orbital angular momentum axes aligned with the spin axis of their host star, Kepler-56 is an exception: its two transiting planets are coplanar yet misaligned by at least 40 degrees with respect to their host star. Additional follow-up observations of Kepler-56 suggest the presence of a massive, non-transiting companion that may help explain this misalignment. We model the transit data along with Keck/HIRES and HARPS-N radial velocity data to update the masses of the two transiting planets and infer the physical properties of the third, non-transiting planet. We employ a Markov Chain Monte Carlo sampler to calculate the best-fitting orbital parameters and their uncertainties for each planet. We find the outer planet has a period of 1002 $\pm$ 5 days and minimum mass of 5.61 $\pm$ 0.38 Jupiter masses. We also place a 95% upper limit of 0.80 m/s/yr on long-term trends caused by additional, more distant companions.

description: Material constitutive models are important to predict deformation behaviour of materials. To identify parameters of constitutive models for high-strain-rate forming, appropriate methods are needed to investigate the dynamic behaviour of materials. Electromagnetic forming is a high-velocity and high-strain-rate forming process in which velocities of up to 300 m/s and strain rates of more than 103 s−1 can be achieved. Recently, the development of Photon Doppler Velocimetry (PDV) enables the accurate measurement of high velocity, and the electromagnetism module of LS-DYNA allows the reliable simulation of electromagnetic forming. In this study, PDV and LS-DYNA were applied to investigate the electromagnetic tube expansion of Al 6061-T6. The experimental and simulation results are presented and discussed to study the dynamic behaviour of Al 6061-T6 and to verify constitutive model parameters for it.

description: Neutron star high mass X-ray binaries with superorbital modulations in luminosity host warped inner accretion disks that occult the neutron star during precession. In SMC X-1, the instability in the warped disk geometry causes superorbital period "excursions:" times of instability when the superorbital period decreases from its typical value of 55 days to $\sim$40 days. Disk instability makes SMC X-1 an ideal system in which to investigate the effects of variable disk geometry on the inner accretion flow. Using the high resolution spectral and timing capabilities of the Neutron Star Interior Composition Explorer (NICER) we examined the high state of four different superorbital cycles of SMC X-1 to search forchanges in spectral shape and connections to the unstable disk geometry. We performed pulse phase-averaged and phase-resolved spectroscopy to closely compare the changes in spectral shape and any cycle-to-cycle variations. While some parameters including the photon index and absorbing column density show slight variations with superorbital phase, these changes are most evident during the intermediate state of the supeorbital cycle. Few spectral changes are observed within the high state of the superorbital cycle, possibly indicating the disk instability does not significantly change SMC X-1's accretion process.

description: Field models with $n$ extra spatial dimensions have a larger $SO(1,3+n)$ Lorentz symmetry which is broken down to the standard $SO(1,3)$ four dimensional one by the compactification process. By considering Lorentz violating operators in a $5D$ supersymmetric Wess-Zumino mo\-del, which otherwise conserve the standard four dimensional Poincare invariance, we show that supersymmetry can be restored upon a simple deformation of the supersymmetric transformations. However, supersymmetry is not preserved in the effective $4D$ theory that arises after compactification when the $5D$ Lorentz violating operators do not preserve $Z_2: y\rightarrow -y$ bulk parity. Our mechanism unveils a possible connection among Lorentz violation and the Scherk-Schwarz mechanism. We also show that parity preserving models, on the other hand, do provide well defined supersymmetric KK models.

description: Future experiments at the Jefferson Lab 12 GeV upgrade, in particular, the Solenoidal Large Intensity Device (SoLID), aim at a very precise data set in the region where the partonic structure of the nucleon is dominated by the valence quarks. One of the main goals is to constrain the quark transversity distributions. We apply recent theoretical advances of the global QCD extraction of the transversity distributions to study the impact of future experimental data from the SoLID experiments. Especially, we develop a simple strategy based on the Hessian matrix analysis that allows one to estimate the uncertainties of the transversity quark distributions and their tensor charges extracted from SoLID data simulation. We find that the SoLID measurements with the proton and the effective neutron targets can improve the precision of the u- and d-quark transversity distributions up to one order of magnitude in the range 0.05 < x < 0.6.

description: Using simultaneous multi-filter observations during the transit of an exoplanet around a K dwarf star, we determine the temperature of a starspot through modeling the radius and position with wavelength-dependent spot contrasts. We model the spot using the starspot modeling program STarSPot (STSP), which uses the transiting companion as a knife-edge probe of the stellar surface. The contrast of the spot, i.e. the ratio of the integrated flux of a darker spot region to the star's photosphere, is calculated for a range of filters and spot temperatures. We demonstrate this technique using simulated data of HAT-P-11, a K dwarf (T = 4780 K) with well-modeled starspot properties for which we obtained simultaneous multi-filter transits using LCO's MuSCAT3 instrument on the 2-meter telescope at Haleakala Observatory which allows for simultaneous, multi-filter, diffuser assisted high-precision photometry. We determine the average (i.e. a combination of penumbra and umbra) spot temperature for HAT-P-11's spot complexes is 4500 K $\pm$ 100 K using this technique. We also find for our set of filters that comparing the SDSS g' and i' filters maximizes the signal difference caused by a large spot in the transit. Thus, this technique allows for the determination of the average spot temperature using only one spot occultation in transit and can provide simultaneous information on the spot temperature and spot properties.

description: The aim of this study is to examine, to what extent the chance of survival of children under 5 years of age was influenced by a biological parent’s death in the region of western Bohemia. Young children’s mortality is considered in relation to family structure, since persons raising the child in its early childhood significantly influenced the quality of child care. Given the gender-specific division of labour in pre-modern families we focus chiefly on the possible different effects of a mother’s death or a father’s death. In addition, we try to establish whether the negative impact of a biological parent’s death could be compensated by the entrance of a stepparent. For the purposes of this analysis we used the Cox proportional hazards mixed-effect model. Our research has shown that although maternal death had more serious consequences compared to paternal death, especially if it occurred in the child’s first year of life, even paternal death increased child mortality since the need to assume the paternal role prevented the surviving mother from taking optimum care of her children. The entrance of a stepparent in general increased children’s chance of survival although in the case of stepmothers the positive effect was limited and could mainly be observed among children over 3. In contrast, our research has shown that there was no major difference in survival chances resulting from the presence of a biological father vs. a stepfather, an interesting result demonstrating that in the functioning of the pre-modern family biological ties were of only relative importance.
Weakening and Shifting of the Saharan Shallow Meridional Circulation During Wet Years of the West African Monsoon

description: The correlation between increased Sahel rainfall and reduced Saharan surface pressure is well established in observations and global climate models, and has been used to imply that increased Sahel rainfall is caused by a stronger shallow meridional circulation (SMC) over the Sahara. This study uses two atmospheric reanalyses to examine interannual variability of Sahel rainfall and the Saharan SMC, which consists of northward near-surface flow across the Sahel into the Sahara and southward flow near 700 hPa out of the Sahara. During wet Sahel years, the Saharan SMC shifts poleward, producing a drop in low-level geopotential and surface pressure over the Sahara. Statistically removing the effect of the poleward shift from the low-level geopotential eliminates significant correlations between this geopotential and Sahel precipitation. As the Saharan SMC shifts poleward, its mid-tropospheric divergent outflow decreases, indicating a weakening of its overturning mass flux. The poleward shift and weakening of the Saharan SMC during wet Sahel years is reproduced in an idealized model of West Africa; a wide range of imposed sea surface temperature and land surface albedo perturbations in this model produce a much larger range of SMC variations that nevertheless have similar quantitative associations with Sahel rainfall as in the reanalyses. These results disprove the idea that enhanced Sahel rainfall is caused by strengthening of the Saharan SMC. Instead, these results are consistent with the hypothesis that the a stronger SMC inhibits Sahel rainfall, perhaps by advecting mid-tropospheric warm and dry air into the precipitation maximum.

description: A likely starburst galaxy (SBG), IRAS 13052-5711, which is the most distant SBG candidate discovered to date, was found by analyzing 14.4 years of data from the Fermi large-area telescope (Fermi-LAT). This SBG's significance level is approximately 6.55$σ$ in the 0.1-500 GeV band. Its spatial position is close to that of 4FGL J1308.9-5730, determined from the Fermi large telescope fourth-source Catalog (4FGL). Its power-law spectral index is approximately 2.1, and its light curve (LC) for 14.4 years has no significant variability. These characteristics are highly similar to those of SBGs found in the past. We calculate the SBG's star formation rate (SFR) to be 29.38 $\rm M_{\odot}\ yr^{-1}$, which is within the SFR range of SBGs found to date. Therefore, IRAS 13052-5711 is considered to be a likely SBG. In addition, its 0.1-500 GeV luminosity is (3.28 $\pm$ 0.67) $\times 10^{42}\ \rm erg\ s^{-1}$, which deviates from the empirical relationship of the $γ$-ray luminosity and the total infrared luminosity. We considered a hadronic model to explain the GeV spectrum of IRAS 13052-5711.

description: The Earth System Grid Federation (ESGF) data nodes are usually the first address for accessing climate model datasets from WCRP-CMIP activities. It is currently hosting different datasets in several projects, e.g., CMIP6, CORDEX, Input4MIPs or Obs4MIPs. Datasets are usually hosted on different data nodes all over the world while data access is managed by any of the ESGF web portals through a web based GUI or the ESGF Search RESTful API. The ESGF data nodes provide different access methods, e.g., https, opendap or globus.
 Beyond ESGF, there has been the Pangeo / ESGF Cloud Data Working Group that coordinates efforts related to storing and cataloging CMIP data in the cloud, e.g., in the Google cloud and in the Amazon Web Services Simple Storage Service (S3) where a large part of the WCRP-CMIP6 ensemble of global climate simulations is now available in analysis-ready cloud-optimized (ARCO) zarr format. The availibility in the cloud has signifcantly lowered the barrier for users with limited resources and no access to an HPC environment to work with CMIP6 datasets and at the same time increases the chance for reproducibilty and reusability of scientific results.
 We are now in the process of adapting the Pangeo strategy for publishing also regional climate model datasets from the CORDEX initiative on AWS S3 cloud storage. Thanks to similar data formats and meta data conventions in comparison to the global CMIP6 datasets, the workflows require only minor adaptations. In this talk, we will show the strategy and workflow implemented in python and orchestrated in github actions workflows as well as a demonstration of how to access CORDEX datasets in the cloud.

description: Modern control is implemented with digital microcontrollers, embedded within a dynamical plant that represents physical components. We present a new algorithm based on counter-example guided inductive synthesis that automates the design of digital controllers that are correct by construction. The synthesis result is sound with respect to the complete range of approximations, including time discretization, quantization effects, and finite-precision arithmetic and its rounding errors. We have implemented our new algorithm in a tool called DSSynth, and are able to automatically generate stable controllers for a set of intricate plant models taken from the literature within minutes.

title: Investigating manual performance when using push buttons following cold water hand immersion
Creators: name: Major, Alexandria

description: The research in this thesis investigates manual performance of humans when using push buttons following cold water hand immersion. An experiment involving 29 human participants was carried out to measure the activation rate for two types of commercially available personal locator beacons after their hands were immersed in either cold water (2 °C) or thermoneutral water (34 °C) for 2 minutes. Similarly, the activation rate was measured for a range of different push buttons mounted on a novel test apparatus after their dominant hand was immersed in both cold (2 °C) and thermoneutral (34 °C) water for 2 minutes. A series of standardized hand dexterity tests were completed to assess the participants baseline tactile sensitivity. The mean baseline performance of participants indicates that they were representative of the general population. The button test apparatus test was developed specifically for this experiment and was comprised of 12 different buttons at different locations on the panel which were varying in size, surface shape and texture. After the participants immersed their dominant hand in the assigned temperature condition, their index finger was guided to the centre of the panel, and they were instructed to find and press as many buttons as they could in a 2-minute time period with only their index finger. Repeat presses were permitted. For both the button panel test and the PLB test, the participants’ view was obstructed from seeing the buttons. After the experiments were completed a questionnaire was given to the participants for them to fill out. The questionnaire consisted of a variety of questions which related to performance feedback of both the PLB tests (Stage 2 & Stage 4) and the button panel apparatus test (Stage 3). This was to have results of how they thought they performed in comparison to how they had performed in the experimental session. Based on the findings from the previous research, it was hypothesized that having cold wet hands would lead to a poorer performance for push button activation than when having warm wet hands. Additionally, it was hypothesized that a button which was large, protruding, and rough would be activated most frequently. The results of the study show that temperature does not influence the activation rate for personal locator beacons or the activation rate of the push buttons on the button test apparatus. In addition, button size (large) was the most significant factor, followed by shape (protruding), however button texture was not a significant parameter. For the application of the activation of PLBs false activation rate occurred and this requires further investigation. For the PLB tests which were conducted it was evident that the two devices were difficult to activate for both hand immersion temperature conditions (thermoneutral and warm).

description: The security of energy supply has again become a similarly hot topic as it was during the oil crises in the 1970s, not least due to the recent historical oil price peaks. In this paper, we analyze the energy security situation of the G7 countries using a statistical risk indicator and empirical energy data for the years 1978 through 2010. We find that Germany’s energy supply risk has risen substantially since the oil price crises of the 1970s, whereas France has managed to reduce its risk dramatically, most notably through the deployment of nuclear power plants. As a result of the nuclear phase-out decision of 2011, Germany’s supply risk can be expected to rise further and to approach the level of Italy. Due to its resource poverty, Italy has by far the highest energy supply risk among G7 countries.

description: Aluminium alloys is desirable for the automotive and electronic appliances industries due to their high strength-to-weight ratio, corrosion resistance and weldability. However applications of the aluminium alloys were very difficult because aluminium alloys formability is very low at room temperature, despite their advantages. One of the high speed forming technologies is Electromagnetic Metal Forming (EMF), which can be useful forming method for low formability light-weight materials such as aluminium, magnesium alloys in overcoming the limitations of conventional forming methods. EMF process refers to the high velocity and high strain rate deformation of low-formability materials driven by electromagnetic forces that are generated by the rapid discharge current through forming coil. This technology depends on the properties of the sheet metal, as well as the process factors such as electromagnetic force in a practical forming operation. Moreover selection of proper shape of forming coil is most important to achieve the desired deformation using the EMF process. Therefore, the purpose of this study is to analyse of the dynamic behaviours on workpiece according to various forming coil shape with aluminium alloys. To achieve these objectives, a magnetic pulse forming system consisting of a 24kJ electromagnetic power source and a bar-type and helical-type forming coil was employed in an experiment. Then, deformation depth was measured for analyse dynamic behaviours on workpiece. The results showed that as the electromagnetic force increases, surface damage to part of the workpiece will increase and according to the shape of forming coil, distribution of electromagnetic force applied on workpiece is changed in EMF process.
