description: Millisecond pulsars (MSPs) are generally believed to be old neutron stars (NSs) which have been spun up to high rotation rates via accretion of matter from a companion star in a low-mass X-ray binary (LMXB). However, many details of this recycling scenario remain to be understood. Here we investigate binary evolution in close LMXBs to study the formation of radio MSPs with low-mass helium white dwarf companions (He WDs) in tight binaries with orbital periods P_orb = 2-9 hr. In particular, we examine: i) if such observed systems can be reproduced from theoretical modelling using standard prescriptions of orbital angular momentum losses (i.e. with respect to the nature and the strength of magnetic braking), ii) if our computations of the Roche-lobe detachments can match the observed orbital periods, and iii) if the correlation between WD mass and orbital period (M_WD, P_orb) is valid for systems with P_orb < 2 days. Numerical calculations with a detailed stellar evolution code were used to trace the mass-transfer phase in ~ 400 close LMXB systems with different initial values of donor star mass, NS mass, orbital period and the so-called gamma-index of magnetic braking. Subsequently, we followed the orbital and the interior evolution of the detached low-mass (proto) He WDs, including stages with residual shell hydrogen burning. We find that a severe fine-tuning is necessary to reproduce the observed MSPs in tight binaries with He WD companions of mass < 0.20 M_sun, which suggests that something needs to be modified or is missing in the standard input physics of LMXB modelling. We demonstrate that the theoretically calculated (M_WD, P_orb)-relation is in general also valid for systems with P_orb < 2 days, although with a large scatter in He WD masses between 0.15-0.20 M_sun. The results of the thermal evolution of the (proto) He WDs are reported in a follow-up paper (Paper II).

description: Das ethnografische Material wurde in der Redaktion des Science Media Center Germany gesammelt: Einer unabhängigen, intermediären Organisation zwischen Wissenschaft und Journalismus, die wissenschaftliche Expertise für die journalistische Nutzung auswählt und aufbereitet. Das Forschungsinteresse galt den Praktiken der redaktionellen Themenauswahl, den Organisationsstrukturen und dem Selbstverständnis des einzigartigen Akteurs in der deutschen Wissenschaftskommunikationslandschaft. Unerwartet kollidierte der einmonatige geplante Forschungsaufenthalt in der Redaktion im Januar 2020 mit dem ersten Ausbruch des neuartigen Coronavirus in Europa. Die in Interviews, Beobachtungen von Redaktionssitzungen und Chatprotokollen gesammelten ethnografischen Daten zeigen, wie die Redakteur:innen auf den anfänglichen Mangel an wissenschaftlichem Wissen und die unsichere Situation reagierten, z.B. durch die Nutzung vorhandener Beziehungen zu passenden wissenschaftlichen Expert:innen, die Anpassung der Auswahlkriterien zur Berücksichtigung wissenschaftlicher Preprints und die Entwicklung neuer Sendeformate, um den akuten Bedürfnissen im Journalismus gerecht zu werden. Auf der Grundlage dieser Erkenntnisse wurde mitten in der COVID-19-Pandemie im Oktober 2020 eine weitere Ethnografie initiiert. Das Interesse galt dabei der Entwicklung der redaktionellen Praktiken und des Selbstverständnisses der Organisation hinsichtlich ihrer Rolle in der Wissenschaftskommunikation in einer Zeit, in der Wissenschaftsthemen öffentlich rasch an Bedeutung gewannen. Diese Feldphase wurde als „hybride" Ethnografie mit drei Wochen digitaler und einer Woche physischer Präsenz konzipiert. Dies ermöglichte zudem vergleichende Einblicke in die redaktionelle Arbeitsorganisation unter Heimarbeitsbedingungen.

description: Microsomal and mitochondrial isoforms of glycerol-3-phosphate acyltransferase (GPAT; E.C. 2.3.1.15) catalyze the committed step in glycerolipid synthesis. The mitochondrial isoform, mtGPAT, was believed to control the positioning of saturated fatty acids at the sn-1 position of phospholipids, and nutritional, hormonal, and overexpression studies suggested that mtGPAT activity is important for the synthesis of triacylglycerol. To determine whether these purported functions were true, we constructed mice deficient in mtGPAT. mtGPAT−/− mice weighed less than controls and had reduced gonadal fat pad weights and lower hepatic triacylglycerol content, plasma triacylglycerol, and very low density lipoprotein triacylglycerol secretion. As predicted, in mtGPAT−/− liver, the palmitate content was lower in triacylglycerol, phosphatidylcholine, and phosphatidylethanolamine. Positional analysis revealed that mtGPAT−/− liver phosphatidylethanolamine and phosphatidylcholine had about 21% less palmitate in the sn-1 position and 36 and 40%, respectively, more arachidonate in the sn-2 position. These data confirm the important role of mtGPAT in the synthesis of triacylglycerol, in the fatty acid content of triacylglycerol and cholesterol esters, and in the positioning of specific fatty acids, particularly palmitate and arachidonate, in phospholipids. The increase in arachidonate may be functionally significant in terms of eicosanoid production.

Interplay between these two phenomena is being investigated. Depending on the mean-field potential parameters one can observe two types of critical points, called "Boltzmann" and "Bose", that belong to different universality classes with distinct sets of critical exponents. As examples of Bose and Boltzmann CPs pion and $α$ matter are considered, respectively. In general, the phase diagram can have one of the CPs or both of them.

Nitrogen cycling in salt-marsh and mangrove sediments at Western Port, Victoria

MDFRC item.

The metabolism of organic nitrogen compounds in sediments from salt-marsh (Sarcocornia quinqueflora) and mangrove (Avicennia marina) areas at Western Port, Victoria, was investigated. Organic nitrogen compounds were metabolized at potential rates of up to 3.9 µmol cmF3 day-1 for amino acids, 23 µmol cm-3 day-( for dipeptides, and 5 µmol cm-1 day-1 for an amide. These were higher than the rate of ammonium regeneration in the absence of added substrate (<0.08 µmol cm-3 day-1); this indicates that organic nitrogenous compounds play a major role in nutrient cycling in coastal sediments. Rates of some transformations were highly correlated with sediment organic-matter content, total nitrogen content or concentration of soluble reactive phosphorus in the sediments, but overall there were few significant correlations between metabolic rates and edaphic conditions. Degradation of organic nitrogenous compounds in these sediments is likely to be influenced strongly by the availability of phosphorus, the quantity and quality of detrital inputs, and the size and activity of microbial populations.

description: Das Projekt richtete sich auf die gesamte Statuspassage von der Berufsfindung über die Berufsausbildung bis in die ersten Jahre im Beschäftigungssystem. In einer quantitativen und qualitativen Längsschnittstudie wurden junge Fachkräfte aus sechs ausgewählten Berufen in zwei unterschiedlich strukturierten Arbeitsmarktregionen untersucht. Besonderes Interesse galt dabei der Frage, wie die Erfahrungen mit den regionalen Chancenstrukturen zum Zeitpunkt der Berufsentscheidung und Lehrstellensuche Mitte der 80er Jahre und der Arbeitsmarktentspannung in den darauf folgenden Ausbildungs- und Berufsjahren auf den Verlauf des Berufsstarts einwirken und welche Konsequenzen für berufliches Handeln hieraus gezogen werden. Das Projekt trägt zur Erforschung der Strukturierung sozialer Ungleichheit in der Phase der Arbeitsmarktintegration und Familiengründung bei. Es wurden Ausbildungsabsolventen des Jahres 1989 kurz vor Ende der Ausbildung sowie ein Jahr danach über die bisherigen Stationen ihres Bildungs - und Berufsverlaufs befragt. In der letzten Projektphase wurde die Befragung thematisch auf die Verknüpfung mit den Passagen in Partnerschaft und Familie ausgedehnt. Eine auf Basis der quantitativen Längsschnittstudie erstellte Typologie bildete die Grundlage für die Auswahl der Jugendlichen, mit denen dreimalig problemzentrierte Interviews durchgeführt wurden. Im Mittelpunkt der Interviews standen Fragen nach Stabilität bzw. Veränderung der Arbeitsorientierungen, Beschäftigungsinteressen und Strategien der Bewältigung der regional und nach Ausbildungsberuf unterschiedlich ausgeprägten Übergangsrisiken. Der vorliegende Studienreport fokussiert die inhaltlichen und methodisch-konzeptionellen Grundlagen der über Qualiservice zur Verfügung gestellten Interviews. Es werden die Forschungsfragen, das Vorgehen bei der Fallauswahl sowie die Erhebung der Daten über problemzentrierte Interviews dargelegt.
Molecular Anatomy of the Human Excision Nuclease Assembled at Sites of DNA Damage

description: Human nucleotide excision repair is initiated by six repair factors (XPA, RPA, XPC-HR23B, TFIIH, XPF-ERCC1, and XPG) which sequentially assemble at sites of DNA damage and effect excision of damage-containing oligonucleotides. We here describe the molecular anatomy of the human excision nuclease assembled at the site of a psoralen-adducted thymine. Three polypeptides, primarily positioned 5′ to the damage, are in close physical proximity to the psoralen lesion and thus are cross-linked to the damaged DNA: these proteins are RPA70, RPA32, and the XPD subunit of TFIIH. While both XPA and XPC bind damaged DNA and are required for XPD cross-linking to the psoralen-adducted base, neither XPA nor XPC is cross-linked to the psoralen adduct. The presence of other repair factors, in particular TFIIH, alters the mode of RPA binding and the position of its subunits relative to the psoralen lesion. Based on these results, we propose that RPA70 makes the initial contact with psoralen-damaged DNA but that within preincision complexes, it is RPA32 and XPD that are in close contact with the lesion.

description: We combine in-situ electrical transport and Seebeck coefficient measurements with the ionic liquid gating technique to investigate superconductivity and the normal state of FeySe1-xTex (FST) films. We find that the pristine FST films feature a non-Fermi liquid temperature dependence of the Seebeck coefficient, i.e., S/T ~ AS lnT, and AS is strongly correlated with the superconducting transition temperature (Tc). Ionic liquid gating significantly raises Tc of FST films, for which the Seebeck coefficient displays a novel scaling behavior and retains the logarithmic temperature dependence. Moreover, a quantitative relationship between the slope of T-linear resistivity (A\r{ho}) and Tc for gated films is observed, i.e., (A\r{ho})1/2 ~ Tc, consistent with previous reports on cuprates and FeSe. The scaling behaviors of AS and A\r{ho} point to a spin-fluctuation-associated transport mechanism in gated FeySe1-xTex superconductors.

description: Lower-hybrid current drive (LHCD) actuators are important components of modern day fusion experiments as well as proposed fusion reactors. However, simulations of LHCD often differ substantially from experimental results, and from each other, especially in the inferred power deposition profile shape. Here we investigate some possible causes of this discrepancy; "full-wave" effects such as interference and diffraction, which are omitted from standard raytracing simulations and the breakdown of the raytracing near reflections and caustics. We compare raytracing simulations to state-of-the-art full-wave simulations using matched hot-plasma dielectric tensors in realistic tokamak scenarios for the first time. We show that differences between full-wave simulations and raytracing in previous work were primarily due to numerical and physical inconsistencies in the simulations, and we demonstrate that good agreement between raytracing and converged full-wave simulations can be obtained in reactor relevant-scenarios with large ray caustics and in situations with weak damping.

description: We analyzed the Einstein radius, $θ_E$, in our sample of SL2S galaxy groups, and compared it with $R_A$ (the distance from the arcs to the center of the lens), using three different approaches: 1.- the velocity dispersion obtained from weak lensing assuming a Singular Isothermal Sphere profile ($θ_{E,I}$), 2.- a strong lensing analytical method ($θ_{E,II}$) combined with a velocity dispersion-concentration relation derived from numerical simulations designed to mimic our group sample, 3.- strong lensing modeling ($θ_{E,III}$) of eleven groups (with four new models presented in this work) using HST and CFHT images. Finally, $R_A$ was analyzed as a function of redshift $z$ to investigate possible correlations with L, N, and the richness-to-luminosity ratio (N/L). We found a correlation between $θ_{E}$ and $R_A$, but with large scatter. We estimate $θ_{E,I}$ = (2.2 $\pm$ 0.9) + (0.7 $\pm$ 0.2)$R_A$, $θ_{E,II}$ = (0.4 $\pm$ 1.5) + (1.1 $\pm$ 0.4)$R_A$, and $θ_{E,III}$ = (0.4 $\pm$ 1.5) + (0.9 $\pm$ 0.3)$R_A$ for each method respectively. We found a weak evidence of anti-correlation between $R_A$ and $z$, with Log$R_A$ = (0.58$\pm$0.06) - (0.04$\pm$0.1)$z$, suggesting a possible evolution of the Einstein radius with $z$, as reported previously by other authors. Our results also show that $R_A$ is correlated with L and N (more luminous and richer groups have greater $R_A$), and a possible correlation between $R_A$ and the N/L ratio. Our analysis indicates that $R_A$ is correlated with $θ_E$ in our sample, making $R_A$ useful to characterize properties like L and N (and possible N/L) in galaxy groups. Additionally, we present evidence suggesting that the Einstein radius evolves with $z$.

description: We report progress on the ongoing recalibration of the Wolf sunspot number (SN) and Group sunspot number (GN) following the release of version 2.0 of SN in 2015. This report constitutes both an update of the efforts reported in the 2016 Topical Issue of Solar Physics and a summary of work by the International Space Science Institute (ISSI) International Team formed in 2017 to develop optimal SN and GN re-construction methods while continuing to expand the historical sunspot number database. Significant progress has been made on the database side while more work is needed to bring the various proposed SN and (primarily) GN reconstruction methods closer to maturity, after which the new reconstructions (or combinations thereof) can be compared with (a) ``benchmark'' expectations for any normalization scheme (e.g., a general increase in observer normalization factors going back in time), and (b) independent proxy data series such as F10.7 and the daily range of variations of Earth's undisturbed magnetic field. New versions of the underlying databases for SN and GN will shortly become available for years through 2022 and we anticipate the release of next versions of these two time series in 2024.

description: We showed previously that activated Ras, but not Raf, causes transformation of RIE-1 epithelial cells, demonstrating the importance of Raf-independent pathways in mediating Ras transformation. To assess the mechanism by which Raf-independent effector signaling pathways contribute to Ras-mediated transformation, we recently utilized representational difference analysis to identify genes expressed in a deregulated fashion by activated Ras but not Raf. One gene identified in these analyses encodes for α-tropomyosin. Therefore, we evaluated the mechanism by which Ras causes the downregulation of tropomyosin expression. By using RIE-1 cells that harbor inducible expression of activated H-Ras(12V), we determined that the downregulation of tropomyosin expression correlated with the onset of morphological transformation. We found that the reversal of Ras transformation caused by inhibition of extracellular signal-regulated kinase activation corresponded to a restoration of tropomyosin expression. Inhibition of p38 activity in Raf-expressing RIE-1 cells caused both morphological transformation and loss of tropomyosin expression. Thus, a reduction in tropomyosin expression correlated strictly with morphological transformation of RIE-1 cells. However, forced overexpression of tropomyosin in Ras-transformed cells did not reverse morphological or growth transformation, a finding consistent with the possibility that multiple changes in gene expression contribute to Ras transformation. We also determined that tropomyosin expression was low in two human tumor cell lines, DLD-1 and HT1080, that harbor endogenous mutated alleles of ras, but high in transformation-impaired, derivative cell lines in which the mutant ras allele has been genetically deleted. Finally, treatment with azadeoxycytidine restored tropomyosin expression in Ras-transformed RIE-1, HT1080, and DLD-1 cells, suggesting a role for DNA methylation in downregulating tropomyosin expression.

description: Being able to design genetic regulatory networks (GRNs) to achieve a desired cellular function is one of the main goals of synthetic biology. However, determining minimal GRNs that produce desired time-series behaviors is non-trivial. In this paper, we propose a 'top-down' approach to evolving small GRNs and then use these to recursively boot-strap the identification of larger, more complex, modular GRNs. We start with relatively dense GRNs and then use differential evolution (DE) to evolve interaction coefficients. When the target dynamical behavior is found embedded in a dense GRN, we narrow the focus of the search and begin aggressively pruning out excess interactions at the end of each generation. We first show that the method can quickly rediscover known small GRNs for a toggle switch and an oscillatory circuit. Next we include these GRNs as non-evolvable subnetworks in the subsequent evolution of more complex, modular GRNs. Successful solutions found in canonical DE where we truncated small interactions to zero, with or without an interaction penalty term, invariably contained many excess interactions. In contrast, by incorporating aggressive pruning and the penalty term, the DE was able to find minimal or nearly minimal GRNs in all test problems.

description: We investigate the specific heat of ultra-pure single crystals of Sr2RuO4, a leading candidate of a spin-triplet superconductor. We for the first time obtained specific-heat evidence of the first-order superconducting transition below 0.8 K, namely divergent-like peaks and clear hysteresis in the specific heat at the upper critical field. The first-order transition occurs for all in-plane field directions. The specific-heat features for the first-order transition are found to be highly sensitive to sample quality; in particular, the hysteresis becomes totally absent in a sample with slightly lower quality. These thermodynamic observations provide crucial bases to understand the unconventional pair-breaking effect responsible for the first-order transition.

Oxygen transport in the submerged freshwater macrophyte Egeria densa planch. II. Role of lacunar gas pressures

MDFRC item.

A pressure transducer was used to measure internal gas pressures (pI) in the lacumar system of Egeria densa Planch. Under illumination, pI values up to 25 kPa above atmospheric developed in shoots in unstirred water. Upon circulation of the water, pI values decreased to 50–90% of the maximal values in unstirred water. Positive pressures, indicating partitioning of photosynthetic O2 into the lacunae, were recorded in both re-circulating and open-circuit flow. When the shoot was darkened, negative internal pressures (5–10 kPa below atmospheric) developed.The pressure gradient (Δp) required to drive O2 transport in the lacunar system was calculated from the Hagen-Poiseuille equation. This gradient was 9.15 × 10−4 kPa m−1. Manometric measurements of pI and pressure transfer rates showed that transient gradients of approximately 0.9 kPa m−1 developed following dark to light changes. However, pressure equilibration (mean rate = 0.02 m s−1) resulted in rapid attainment of constant pI under steady-state conditions. It is proposed that O2 transport in Egeria is sustained by simple diffusion, assisted by advective movements under internal pressure gradients that develop following changes in external conditions.

description: The occurrence of heterogeneous perturbations of fluid mass density and solid elastic strain of a porous continuum, as a consequence of its undrained response is a very important topic in theoretical and applied poromechanics. The classical Mandel--Cryer effect provides an explanation of fluid overpressure in the central region of a porous sample, immediately after the application of the loading. However this effect fades away when the fluid leaks out of the porous network. Here this problem is studied within the framework of a second gradient theory and a thorough description of the static and the dynamics of the phenomenon is given.

description: Recent studies have shown the p19ARF tumor suppressor to be involved in the response to oncogenic stress by regulating the activity of p53. This response is mediated by antagonizing the function of Mdm2, a negative regulator of p53, indicating a pathway for tumor suppression that involves numerous genes altered in human tumors. We previously described a transgenic mouse brain tumor model in which oncogenic stress, provided by cell-specific inactivation of the pRb pathway, triggers a p53-dependent apoptotic response. This response suppresses the growth of developing tumors and thus represents a bona fide in vivo tumor suppressor activity. We further showed that E2F1, a transcription factor known to induce p19ARF expression, was required for the response. Here, we use a genetic approach to test whether p19ARF functions to transduce the signal from E2F1 to p53 in this tumor suppression pathway. Contrary to the currently accepted hypothesis, we show that a deficiency in p19ARF has no impact on p53-mediated apoptosis or tumor suppression in this system. All measures of p53 function, including the level of apoptosis induced by pRb inactivation, the expression of p21 (a p53-responsive gene), and the rate of tumor growth, were comparable in mice with and without a functional p19ARF gene. Thus, although p19ARF is required in some cell types to transmit an oncogenic response signal to p53, it is dispensable for this function in an in vivo epithelial system. These results underscore the complexity of p53 tumor suppression and further indicate the existence of distinct cell-specific pathways that respond to similar stimuli.

Following feeding experiments, the distribution of algal cells on the trunk limbs of Daphnia carinata was almost exclusively on the setae and setules of the first two thoracic limbs (I and II). Traditionally, the third and fourth limbs (III and IV) were considered the sites of particle collection by filtration. High speed 16mm cinematography (250 f.p.s, Lo-Cam camera, Wild M – 400 photomacroscope) was used to determine the function(s) of the limbs, particularly whether III and IV were functioning as sieves. Polystyrene beads (5, 9 and 18 µm) and algae (Ankistrodesmus and Scenedesmus) were fed to D. carinata. All particles were handled by limbs I and II, with no evidence of a sieving function by III and IV. There was evidence from the film that the latter limbs are involved in maintaining the currents needed for particle extraction. The limb movements involved sequences that simple filtration is not an adequate description of the process.

description: Young giant planets are the best targets for characterization with direct imaging. The Medium Resolution Spectrometer (MRS) of the Mid-Infrared Instrument (MIRI) of the recently launched James Webb Space Telescope (JWST) will give access to the first spectroscopic data for direct imaging above 5 $μ$m with unprecedented sensitivity at a spectral resolution up to 3700. This will provide a valuable complement to near-infrared data from ground-based instruments for characterizing these objects. We aim to evaluate the performance of MIRI/MRS to detect molecules in the atmosphere of exoplanets and to constrain atmospheric parameters using Exo-REM atmospheric models. The molecular mapping technique, based on cross-correlation with synthetic models, has been introduced recently. This promising detection and characterization method is tested on simulated MIRI/MRS data. Directly imaged planets can be detected with MIRI/MRS, and we are able to detect molecules (H$_2$O, CO, NH$_3$, CH$_4$, HCN, PH$_3$, CO$_2$) at various angular separation depending on the strength of the molecular features and brightness of the target. We find that the stellar spectral type has a weak impact on the detection level. This method is globally most efficient for planets with temperatures below 1500 K, for bright targets and angular separation greater than 1$''$. Our parametric study allows us to anticipate the ability to characterize planets that would be detected in the future. The MIRI/MRS will give access to molecular species not yet detected in exoplanetary atmospheres. The detection of molecules as indicators of the temperature of the planets will make it possible to discriminate between the various hypotheses of the preceding studies, and the derived molecular abundance ratios should bring new constraints on planetary formation scenarios.

description: We explore an exact duality in $(2+1)$d between the fermionization of a bosonic theory with a $\mathbb{Z}_2$ subsystem symmetry and a fermionic theory with a $\mathbb{Z}_2$ subsystem fermion parity symmetry. A typical example is the duality between the fermionization of the plaquette Ising model and the plaquette fermion model. We first revisit the standard boson-fermion duality in $(1+1)$d with a $\mathbb{Z}_2$ 0-from symmetry, presenting in a way generalizable to $(2+1)$d. We proceed to $(2+1)$d with a $\mathbb{Z}_2$ subsystem symmetry and establish the exact duality on the lattice by using the generalized Jordan-Wigner map, with a careful discussion on the mapping of the twist and symmetry sectors. This motivates us to introduce the subsystem Arf invariant, which exhibits a foliation structure.

The timescale of low-mass proto-helium white dwarf evolution

description: A large number of low-mass (< 0.20 M_sun) helium white dwarfs (He WDs) have recently been discovered. The majority of these are orbiting another WD or a millisecond pulsar (MSP) in a close binary system; a few examples are found to show pulsations or to have a main-sequence star companion. There appear to be discrepancies between the current theoretical modelling of such low-mass He WDs and a number of key observed cases, indicating that their formation scenario remains to be fully understood. Here we investigate the formation of detached proto-He WDs in close-orbit low-mass X-ray binaries (LMXBs). Our prime focus is to examine the thermal evolution and the contraction phase towards the WD cooling track and investigate how this evolution depends on the WD mass. Our calculations are then compared to the most recent observational data. Numerical calculations with a detailed stellar evolution code were used to trace the mass-transfer phase in a large number of close-orbit LMXBs. Subsequently, we followed the evolution of the detached low-mass proto-He WDs, including stages with residual shell hydrogen burning and vigorous flashes caused by unstable CNO burning. We find that the time between Roche-lobe detachment until the low-mass proto-He WD reaches the WD cooling track is typically Delta_t_proto = 0.5 - 2 Gyr, depending systematically on the WD mass and therefore on its luminosity. The lowest WD mass for developing shell flashes is ~0.21 M_sun for progenitor stars of mass M2 <= 1.5 M_sun (and ~0.18 M_sun for M2 = 1.6 M_sun). The long timescale of low-mass proto-He WD evolution can explain a number of recent observations, including some MSP systems hosting He WD companions with very low surface gravities and high effective temperatures. We find no evidence for Delta_t_proto to depend on the occurrence of flashes and thus question the suggested dichotomy in thermal evolution of proto-WDs.
