description: Replica exchange molecular dynamics (REMD) becomes more efficient as the frequency of swap between the temperatures is increased. Recently in [Plattner et al, J. Chem. Phys. 135, 134111 (2011)] a method was proposed to implement infinite swapping REMD in practice. Here we show that this method naturally leads to a reformulation in terms of molecular dynamics simulations over a mixture potential, which is both simple to implement in practice and provides a better, energy based understanding of how to choose the temperatures in REMD to optimize efficiency. It also opens the door to generalizations of REMD in which the swaps involve other parameters than the temperature.

description: Das vorliegende Diskussionspapier beschäftigt sich mit den Veränderungen im Bereich der Erwerbs-arbeit, welche aufgrund der COVID-19-Pandemie und den gesetzlichen Maßnahmen zur Eindäm-mung der Pandemie ausgelöst wurden. Hierbei geht es insbesondere um die Analyse der veränder-ten Arbeitspraktiken sowie der Entwicklung neuer Organisationsstrukturen. Ein wesentlicher Fokus liegt auf den neuen Arbeitsbedingungen, der Arbeitszufriedenheit und dem Wohlbefinden. Die Ergebnisse zeigen, dass die Arbeit aufgrund der Pandemie verstärkt in die privaten Räumlichkei-ten verlagert wurde, sodass die gesetzlichen Maßnahmen eingehalten und die Ansteckungsgefahr reduziert werden können. Die gesetzlichen Maßnahmen als auch die Veränderungen innerhalb der Arbeitswelt haben gravierende Auswirkungen auf den Alltag der Bürger*innen, welche sowohl posi-tiv als auch negativ bewertet werden. Die Daten zur Analyse dieser Veränderungen stammen aus dem Forschungsprojekt „Logbuch der Veränderungen“ (LdV) der Hochschule für nachhaltige Ent-wicklung Eberswalde (HNEE). Dabei handelt es sich um eine bürgerwissenschaftliche Online-Tage-buchstudie mit dem Ziel, anhand der COVID-19-Krise Verhaltensveränderungen und gesellschaftli-chen Wandel besser verstehen zu können. Im LdV können insgesamt zu sechs Handlungsfeldern Be-obachtungen festgehalten werden. Diese Arbeit bezieht sich auf das Handlungsfeld „Arbeit“ mit 711 Einträgen. Den theoretischen Rah-men zur Auswertung des Datenmaterials bildete die Praxistheorie. Diese stellt soziale Praktiken bzw. routinierte, meist unbewusste Gewohnheiten ins Zentrum der Betrachtung und erkennt, dass diese eng miteinander verbunden und sozial geteilt sind. Im Zuge der Analyse des Handlungsfelds „Arbeit“ konnten drei Praktiken identifiziert werden: 1) „Home-Office“, 2) „Digitale Kommunikation und digitales Arbeiten“ sowie 3) „Präsenzarbeit“. Zu-sammenfassend zeigt sich, dass aufgrund der Pandemie und der gravierenden Veränderungen in-nerhalb der Erwerbsarbeit neue Arbeitsroutinen entwickelt wurden. Zudem wird deutlich, dass vor allem zu Beginn viele Schwierigkeiten und Herausforderungen im Home-Office eingetreten sind, trotz allem aber bei vielen der Wunsch vorherrscht, auch in Zukunft die Arbeit flexibel im Home-Office als auch im Büro auszuüben. Die Ergebnisse werden aus sozial-ökologischer Perspektive an-hand des Konzepts „Gute Arbeit“ diskutiert.

description: This work compares computational methods for laser pulse propagation in hollow waveguides filled with rare gases at high pressures, with applications in extreme nonlinear optics in the mid-infrared wavelength region. As the wavelength of light λ=2π/k increases with respect to the transverse size R of a leaky waveguide, the loss of light out of the waveguide upon propagation, in general, increases. The now standard numerical approach for studying such structures is based on expansion of the propagating field into approximate leaky waveguide modes. We compare this approach to a new method that resolves the electric field in real space and correctly captures the energy loss through the waveguide wall. The comparison reveals that the expansion-based approach overestimates losses that occur in nonlinearly reshaped pulsed waveforms. For a modest increase in computational effort, the new method offers a physically more accurate model to describe phenomena (e.g., extreme pulse-selfcompression) in waveguides with smaller values of kR.

description: We present the application of a fast quasi-adiabatic continuous method to the measurement of specific heat at 4He temperatures, which can be used for the study of a wide range of materials. The technique can be performed in the same configuration used for the relaxation method, as the typical time constants between calorimetric cell and thermal sink at 4.2 K are chosen to be of the order of tau~30 s. The accuracy in the absolute values have been tested by comparing them to relaxation-method results obtained in the same samples (performed in situ using the same set-up), with a deviation between the absolute values < 3% in the whole temperature range. This new version of the continuous calorimetric method at low temperatures allows us to completely characterize and measure a sample within a few hours with a high density of data points, whereas when employing other methods we typically need a few days. An exhaustive study has been performed for reproducibility to be tested. In the present work, we have applied this method to two different substances: CeSb2, which exhibits three magnetic transitions at 15.5 K, 11.7 K and 9.5 K, and graphite, both highly-oriented pyrolytic graphite (HOPG) and natural crystals. Our results on these graphites are discussed in comparison with previous published data on different kinds of graphite samples.

description: Digitisation involves a comprehensive workplace transformation which is embedded in an overall economic and societal change (globalisation, demographic trends). The currently widely unclear impacts on the labour market resulting from the digitisation of production and business processes as well as from new platform-based forms of work are of particular social importance. The increased flexibility resulting from being able to work anywhere at any time offers employees more autonomy with regard to shaping their work. Partly, however, there is a risk that the boundaries between work and leisure time are blurred and work is intensified which could involve impacts on human health. Currently, the knowledge and data basis for evaluating these ambiguities is very rudimentary and should be improved within the framework of a broadly based research policy.
A Self-Gravitating Disc Around L1527 IRS?

description: Recent observations of the Class 0 protostar L1527 IRS have revealed a rotationally supported disc with an outer radius of at least 100 au. Measurements of the integrated flux at 870 microns suggest a disc mass that is too low for gravitational instability to govern angular momentum transport. However, if parts of the disc are optically thick at sub-mm wavelengths, the sub-mm fluxes will underestimate the disc mass, and the disc's actual mass may be substantially larger, potentially sufficient to be self-gravitating. We investigate this possibility using simple self-gravitating disc models. To match the observed mass accretion rates requires a disc-to-star mass ratio of at least ~0.5, which produces sub-mm fluxes that are similar to those observed for L1527 IRS in the absence of irradiation from the envelope or central star. If irradiation is significant, then the predicted fluxes exceed the observed fluxes by around an order of magnitude. Our model also indicates that the stresses produced by the gravitational instability are low enough to prevent disc fragmentation. As such, we conclude that observations do not rule out the possibility that the disc around L1527 IRS is self-gravitating, but it is more likely that despite being a very young system, this disc may already have left the self-gravitating phase.

A lack of short-period multiplanet systems with close-proximity pairs and the curious case of Kepler 42
Creators: name: Steffen, Jason H.

Publisher: name: arXiv
Year: 2013
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)
subject: FOS: Physical sciences

description: Many Kepler multiplanet systems have planet pairs near low-order, mean-motion resonances. In addition, many Kepler multiplanet systems have planets with orbital periods less than a few days. With the exception of Kepler-42, however, there are no examples of systems with both short orbital periods and nearby companion planets while our statistical analysis predicts ~17 such pairs. For orbital periods of the inner planet that are less than three days, the minimum period ratio of adjacent planet pairs follows the rough constraint P_2/P_1 >~ 2.3 (P_1/day)^(-2/3). This absence is not due to a lack of planets with short orbital periods. We also show a statistically significant excess of small, single candidate systems with orbital periods below 3 days over the number of multiple candidate systems with similar periods---perhaps a small-planet counterpart to the hot Jupiters.

description: We consider the synchrotron emission from electrons out in the Galactic halo bubble region where the Fermi bubble structures reside. Utilizing a simple analytical expression for the non-thermal electron distribution and a toy magnetic field model, we simulate polarized synchrotron emission maps at a frequency of 30 GHz. Comparing these maps with the observational data, we obtain constraints on the parameters of our toy Galactic halo bubble magnetic field model. Utilizing this parameter value range for the toy magnetic field model, we determine the corresponding range of arrival directions and suppression factors of ultra high energy cosmic rays (UHECRs) from potential local source locations. We find that high levels of flux suppression (down to 2 per cent) and large deflection angles (≥80°) are possible for source locations whose line of sight pass through the Galactic halo bubble region. We conclude that the magnetic field out in the Galactic halo bubble region can strongly dominate the level of deflection UHECRs experience whilst propagating from local sources to Earth.

description: We calculate the phonons in a graphene nanoconstriction(GNC) in the presence of a high current density. The Joule-heating, current-induced forces, and coupling to electrode phonons is evaluated using first principles nonequilibrium DFT-NEGF calculations. Close to a resonance in the electronic structure we observe a strongly nonlinear heating with bias and breakdown of the harmonic approximation. This behavior results from negatively damped phonons driven by the current. The effect may limit the stability and capacity of graphene nanoconstrictions to carry high currents.
Effect of a High Opacity on the Light Curves of Radioactively Powered Transients from Compact Object Mergers

Year: 2013
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: The coalescence of compact objects are a promising astrophysical sources of gravitational wave (GW) signals. The ejection of r-process material from such mergers may lead to a radioactively-powered electromagnetic counterpart which, if discovered, would enhance the science return of a GW detection. As very little is known about the optical properties of heavy r-process elements, previous light curve models have adopted opacities similar to those of iron group elements. Here we report that the presence of heavier elements, particularly the lanthanides, increase the ejecta opacity by several orders of magnitude. We include these higher opacities in time dependent, multi-wavelength radiative transport calculations to predict the broadband light curves of one-dimensional models over a range of parameters (ejecta masses from 0.001 to 0.1 solar masses and velocities from 0.1 to 0.3c). We find that the higher opacities lead to much longer duration light curves which can last a week or more. The emission is shifted toward the infrared bands due to strong optical line blanketing, and the colors at later times are representative of a blackbody near the recombination temperature of the lanthanides (T ~ 2500K). We further consider the case in which a second mass outflow, composed of 56Ni, is ejected from a disk wind, and show that the net result is a distinctive two component spectral energy distribution, with a bright optical peak due to 56Ni and an infrared peak due to r-process ejecta. We briefly consider the prospects for detection and identification of these transients.

description: We construct simple triaxial generalisations of Navarro-Frenk-White haloes. The models have elementary gravitational potentials, together with a density that is cusped like 1/r at small radii and falls off like 1/r^3 at large radii. The ellipticity varies with radius in a manner that can be tailored to the user's specification. The closed periodic orbits in the planes perpendicular to the short and long axes of the model are well-described by epicyclic theory, and can be used as building blocks for long-lived discs. As an application, we carry out the simulations of thin discs of satellites in triaxial dark halo potentials. This is motivated by the recent claims of an extended, thin disc of satellites around the M31 galaxy with a vertical rms scatter of ~12 kpc and a radial extent of ~ 300 kpc (Ibata et al. 2013). We show that a thin satellite disc can persist over cosmological times if and only if it lies in the planes perpendicular to the long or short axis of a triaxial halo, or in the equatorial or polar planes of a spheroidal halo. In any other orientation, then the disc thickness doubles on ~5 Gyr timescales and so must have been born with an implausibly small vertical scaleheight.

description: We demonstrate that trapping of dispersive waves between two optical solitons takes place when resonant scattering of the waves on the solitons leads to nearly perfect reflections. The momentum transfer from the radiation to solitons results in their mutual attraction and a subsequent collision. The spectrum of the trapped radiation can either expand or shrink in the course of the propagation, which is controlled by arranging either collision or separation of the solitons.

description: Material ejected during (or immediately following) the merger of two neutron stars may assemble into heavy elements by the r-process. The subsequent radioactive decay of the nuclei can power electromagnetic emission similar to, but significantly dimmer than, an ordinary supernova. Identifying such events is an important goal of future transient surveys, offering new perspectives on the origin of r-process nuclei and the astrophysical sources of gravitational waves. Predictions of the transient light curves and spectra, however, have suffered from the uncertain optical properties of heavy ions. Here we consider the opacity of expanding r-process material and argue that it is dominated by line transitions from those ions with the most complex valence electron structure, namely the lanthanides. For a few representative ions, we run atomic structure models to calculate radiative data for tens of millions of lines. We find that the resulting r-process opacities are orders of magnitude larger than that of ordinary (e.g., iron-rich) supernova ejecta. Radiative transport calculations using these new opacities indicate that the transient emission should be dimmer and redder than previously thought. The spectra appear pseudo-blackbody, with broad absorption features, and peak in the infrared (~1 micron). We discuss uncertainties in the opacities and attempt to quantify their impact on the spectral predictions. The results have important implications for observational strategies to find and study the radioactively powered electromagnetic counterparts to compact object mergers.

description: An ion beam can destabilize Alfvén/ion-cyclotron waves and magnetosonic/whistler waves if the beam speed is sufficiently large. Numerical solutions of the hot-plasma dispersion relation have previously shown that the minimum beam speed required to excite such instabilities is significantly smaller for oblique modes with $\vec k \times \vec B_0\neq 0$ than for parallel-propagating modes with $\vec k \times \vec B_0 = 0$, where $\vec k$ is the wavevector and $\vec B_0$ is the background magnetic field. In this paper, we explain this difference within the framework of quasilinear theory, focusing on low-$β$ plasmas. We begin by deriving, in the cold-plasma approximation, the dispersion relation and polarization properties of both oblique and parallel-propagating waves in the presence of an ion beam. We then show how the instability thresholds of the different wave branches can be deduced from the wave--particle resonance condition, the conservation of particle energy in the wave frame, the sign (positive or negative) of the wave energy, and the wave polarization. We also provide a graphical description of the different conditions under which Landau resonance and cyclotron resonance destabilize Alfvén/ion-cyclotron waves in the presence of an ion beam. We draw upon our results to discuss the types of instabilities that may limit the differential flow of alpha particles in the solar wind.

description: Mit der Digitalisierung geht eine umfassende Transformation der Arbeitswelt einher, die in einen übergreifenden wirtschaftlichen und gesellschaftlichen Wandel eingebettet ist (Globalisierung, demografische Entwicklungen). Von gesellschaftlicher Bedeutung sind insbesondere die derzeit weitgehend unklaren Effekte auf den Arbeitsmarkt, die sich durch die Digitalisierung von Produktions- und Unternehmensprozessen sowie neue plattformbasierte Arbeitsformen ergeben. Die resultierende Flexibilisierung als Folge zeit- und ortsungebundenen Arbeitens gibt Beschäftigten mehr Autonomie in der Arbeitsgestaltung; teilweise droht aber auch eine gesundheitsschädliche Verdichtung und Entgrenzung von Tätigkeiten. Die Daten- und Wissensgrundlage zur Beurteilung dieser Ambivalenzen ist derzeit sehr rudimentär und sollte im Rahmen einer breit ausgerichteten Forschungspolitik verbessert werden.

Roboter bieten prinzipiell das Potenzial, sowohl hilfsbedürftige als auch pflegende Personen zu unterstützen. Für diverse Aufgaben in der Altenpflege befinden sich Prototypen in der Entwicklung, der Transfer in die Praxis ist aber bislang nur ansatzweise gelungen. Grundsätzliche Fragen stellen sich hinsichtlich der gesellschaftlichen Wünschbarkeit eines verbreiteten Robotereinsatzes, vor allem angesichts der grundlegenden Bedeutung der zwischenmenschlichen Interaktion für die Pflegearbeit. Die Gestaltung guter Pflege ist eine gesamtgesellschaftliche Aufgabe. Neben einer bedarfsorientierten Technikentwicklung gehört dazu eine öffentliche Debatte über die zukünftige Rolle der Robotik in der Pflege.

We compared longitudinal trajectories, rates of change and mortality risks of fasting blood glucose, body weight and fat mass in mice, nonhuman primates, and humans throughout their lifespans, and found similar trajectories of body weight and fat in the three species. In contrast, fasting blood glucose decreased late in life in mice but increased over the lifespan of nonhuman primates and humans. Higher glucose was associated with lower mortality in mice, but higher mortality in nonhuman primates and humans, providing a cautionary tale for translating age-associated metabolic changes from mice to humans.

ADDITIVE MICRO- AND NANOPATTERNING FOR THE FABRICATION OF BRAIN CELL NETWORKS
Creators: name: PREVIDI, ANITA
Publisher: name: Universit� degli Studi di Milano

description: The challenges in creating cell cultures with controlled topology and in which cells maintain their in vivo-like phenotype are manifold. Engineering physiologically relevant brain cell networks requires the precise placement of cell bodies in an organized manner while providing the appropriate biophysical cues typical of the native extracellular matrix. In this work, an additive nanofabrication and micropatterning technique is employed to produce nanostructured substrates with complex micropatterns for cell culture aiming at this goal. The strength of this approach resides in the fact that the control on the nanoscale properties of the films, mimicking the native environment of the cells, is combined with the possibility to limit cell adhesion to predetermined substrate areas arranged in patterns. This enables the reproduction of in vitro cell networks with anatomically or functionally relevant geometrical shapes. This thesis provides the details of the method for the fabrication of nanostructured micropatterned films, analysing the advantages and limitations of the technique and providing solutions for obtaining stable and reproducible results. The nanostructured micropatterned substrates were used to characterize the combined effect of the nanoscale topography and cell confinement on astrocytic ensembles. The nanostructure is demonstrated to impact on proliferation, cell morphology, cytoskeletal structure, and calcium activity. It favours the development of astrocytes with morphological features like those found in vivo. Also, the micrometric architecture of the cultures was shown to affect cell morphology and behaviour. Calcium wave signaling was more effective in cells forming elongated clusters with dimension in the same range of blood vessels or axon fibers. The findings of this thesis provide novel insights on the mechanotransductive interaction between astrocytes and the nano- and micro-topographic cues of the cellular microenvironment, while highlighting the crucial role of the biophysical properties of the growth scaffolds to direct brain cell behaviour.

Robotics in the care sector - challenges for society. TAB-Fokus
Creators: name: Kehl, Christoph
Publisher: name: Büro für Technikfolgen-Abschätzung beim Deutschen Bundestag (TAB)
Year: 2018

description: There is hardly any social field that is more affected by ageing of society than care. In the future, significantly increasing care needs as well as a growing shortage of skilled care personnel are to be expected. As a matter of principle, robots offer the potential for supporting both people in need of care and carers. There are prototypes at the development stage that can be used for various tasks with regard to care of the elderly. So far, however, they have been implemented into practice only rudimentarily. Fundamental questions are raised with regard to whether a widespread use of robots would be socially desirable –particularly in view of the essential significance of human interaction for care work. Designing good care is a task of society as a whole. Besides a demand-oriented technology development, this also implies a public debate on the future role of robotics in the care sector.

description: Gynecologic malignancies are a leading cause of death in women worldwide. Standard treatment for many primary and recurrent gynecologic cancer cases includes a combination of external beam radiation, followed by brachytherapy. Magnetic Resonance Imaging (MRI) is benefitial in diagnostic evaluation, in mapping the tumor location to tailor radiation dose, and in monitoring the tumor response to treatment. Initial studies of MR-guidance in gynecologic brachtherapy demonstrate the ability to optimize tumor coverage and reduce radiation dose to normal tissues, resulting in improved outcomes for patients. In this article we describe a methodology to aid applicator placement and treatment planning for 3 Tesla (3T) MR-guided brachytherapy that was developed specifically for gynecologic cancers. This has been used in 18 cases to date in the Advanced Multimodality Image Guided Operating suite at Brigham and Women's Hospital. It is comprised of state of the art methods for MR imaging, image analysis, and treatment planning. An MR sequence using 3D-balanced steady state free precession in a 3T MR scan was identified as the best sequence for catheter identification with ballooning artifact at the tip. 3D treatment planning was performed using MR images. Item in development include a software module designed to support virtual needle trajectory planning that includes probabilistic bias correction, graph based segmentation, and image registration algorithms. The results demonstrate that 3T MR has a role in gynecologic brachytherapy. These novel developments improve targeted treatment to the tumor while sparing the normal tissues.

Soccer

description: Athletes participating in professional soccer are at an increased risk for long-term neurologic disease due to exposure of repetitive head trauma (MacKay et al., 2019). Recent studies have confirmed cases of dementia and chronic traumatic encephalopathy in retired professional soccer players who played during 1966 (McKee et al., 2014; Hales et al., 2014; Bieniek et al., 2015; Ling et al., 2017; Grinberg et al., 2016). It is suspected that repetitive sub concussive impacts from heading may be a contributing factor to the development of chronic neurological deficits (Matser et al., 1998; Witol & Webbe, 2003). It is unknown if current soccer players are at similar risk of brain trauma. Differences of soccer balls, rules changes, and evolution of the game, may have influenced total frequency and impact magnitude of heading. A comparison of frequency and impact magnitude of heading between 1966 and 2018, highlights the potential risk of chronic neurodegeneration in professional soccer players. Ten 1966 and ten 2018 FIFA World Cup matches were randomly chosen for video analysis. Total frequency of headers were documented for each game. Header exemplar reconstructions were completed in the laboratory using a 1966 Slazenger Challenge and 2018 Telstar 18 ball. A pneumatic linear impactor and projectile launcher were used to hit the ball and impact a Hybrid III head form to measure dynamic head response. A finite element model was then used to determine heading magnitudes as measured by Maximal Principal Strain (MPS). The study revealed there were no significant differences in overall frequency of headers between the 1966 and 2018 games. The year 2018 had significantly higher frequency of headers in the medium MPS category while, 1966 had significantly higher frequency in the high category. There were no significant differences of linear acceleration, angular acceleration, and MPS values when comparing the 2018 dry and 1966 dry ball at the same velocity and location. Current athletes who are heading the 2018 Telstar 18 are sustaining similar frequency and magnitudes of heading as athletes in 1966 under the same velocity and impact locations.
Pharmaceutical residues in drinking water and water bodies. TAB-Fokus

description: The consumption of medicines is increasing. Most of the pharmaceutical substances taken by humans and animals are excreted and can be found in many water bodies and partly even in groundwater. Currently, based on existing studies, an acute or chronic health risk from pharmaceutical substances in drinking water can be excluded. However, there are strong indications that pharmaceutical residues in combination with other micropollutants affect aquatic communities. Overall, there are still gaps of knowledge with regard to the occurrence and effects of pharmaceutical residues in the environment. With a series of measures, it is possible to reduce the discharge of pharmaceutical substances into the aquatic environment – without compromising health protection. Here, a combination of different measures seems to make sense. In this context, there is an intense debate focusing on the upgrading of large sewage treatment plants with a fourth treatment stage. It is necessary to consider which tangible measures should be taken within the framework of a comprehensive micropollutant strategy that is to be pursued.

description: Results of the latest financial profile study of U.S. farmer cooperatives are reported. The study is based on a survey of the financial characteristics of farmer cooperatives at the end of their 1987 fiscal years. Useful financial information is provided to cooperative managers, directors, educators, and others interested in cooperatives’ financial performance and practices. Specifically, this report analyzes the distribution of net margins and losses, per-unit capital retain deductions, financial structure, composition of equity capital, and sources of borrowed capital. Financial ratio analysis is conducted to analyze the general financial condition of cooperatives. Cooperatives are classified by principal product or function, major function, asset size, and farm credit district.

description: In view of the recent measurement of nonzero $θ_{13}$, we carry out a systematic study of a simple class of neutrino models that has one diagonal texture or cofactor zero in the mass matrix. There are seven free parameters in the model and five of them are already measured by neutrino oscillation experiments; some cases for the normal or inverted hierarchy are excluded and for the rest we obtain the preferred values for the lightest neutrino mass and Dirac CP phase. We find that there are strong similarities between one diagonal texture zero models with one mass hierarchy and one diagonal cofactor zero models with the opposite mass hierarchy. We also make predictions for neutrinoless double beta decay for these models. For the one cofactor zero models, we present a simple realization based on a new U(1) gauge symmetry.

description: Recent research in economics emphasizes the role of in utero conditions for the health endowment at birth and in early childhood and for social as well as economic outcomes in later life. This paper analyzes the relation between maternal mental health during pregnancy and birth outcomes of the child. In particular, we analyze the relationship between maternal mental health during pregnancy and the probability of giving birth preterm (PT), having a newborn at low birth weight (LBW) or being small for gestational age (SGA). Based on large population-representative data from the German Socio-Economic Panel (SOEP) and cohort data from the National Educational Panel Study (NEPS), we present extensive descriptive evidence on the relationship between maternal mental health and preterm birth by carrying out OLS estimates controlling for a wide range of socioeconomic characteristics. In addition, we apply matching estimators and mother fixed effects models, which bring us closer toward a causal interpretation of estimates. In summary, the results uniformly provide evidence that poor maternal mental health is a risk factor for preterm birth and low birth weight in offspring. In contrast, we find no evidence for an relationship between maternal mental health and small for gestational age at birth.
