description: The aim of this questionnaire study is to investigate the impact of life-time experiences of violence on the course and severity of endometriosis at a University Endometriosis Center. It also explores women’s attitudes toward medical screening for violence. The questionnaire covered demographic data, medical data, information involving possible experiences of psychological, physical, sexual, and intimate partner violence as well as violence screening in medical care. Questionnaires of 118 participants were analyzed. 41/118 women reported some form of violence (34.8%). These women had a significantly higher risk for severe dysmenorrhea, use of analgesics, and comorbidities in comparison to women without life-time experiences of violence. Statistically significant differences were also found for employment status and impaired working ability. More than 60% of women considered the aspect of violence as important for health. However, only 17.1% of women with experiences of violence recalled being asked about violence by a medical professional. The study results suggest that experiences of violence have a significant impact on the course and severity of endometriosis. The findings highlight the importance of healthcare providers to be aware of the potential impact of violence on women’s health, and routine screening for violence in medical care, especially in women with endometriosis.

description: We review the perturbative QCD approach study of hadronic B decays. Utilizing the constrained parameters in these well measured decay channels, we study most of the possible charmless $B_s \to PP$, $PV$ and $VV$ decay channels in the perturbative QCD approach. In addition to the branching ratios and CP asymmetries, we also give predictions to the polarization fractions of the vector meson final states. The size of SU(3) breaking effect is also discussed. These predictions can be tested by the future LHCb experiment.

description: We derive a high energy factorization theorem for inclusive gluon production in A+A collisions. Our factorized formula resums i) all order leading logarithms (g^2 \ln(1/x_{1,2}))^n of the incoming partons momentum fractions, and ii) all contributions (g ρ_{1,2})^n that are enhanced when the color charge densities in the two nuclei are of order of the inverse coupling-- ρ_{1,2}\sim g^{-1}. The resummed inclusive gluon spectrum can be expressed as a convolution of gauge invariant distributions W[ρ_{1,2}] from each of the nuclei with the leading order gluon number operator. These distributions are shown to satisfy the JIMWLK equation describing the evolution of nuclear wavefunctions with rapidity. As a by-product, we demonstrate that the JIMWLK Hamiltonian can be derived entirely in terms of retarded light cone Green's functions without any ambiguities in their pole prescriptions. We comment on the implications of our results for understanding the Glasma produced at early times in A+A collisions at collider energies.

description: We consider the decoding of bit interleaved coded modulation (BICM) applied to multiband OFDM for practical scenarios where only a noisy (possibly very bad) estimate of the channel is available at the receiver. First, a decoding metric based on the channel it a posteriori probability density, conditioned on the channel estimate is derived and used for decoding BICM multiband OFDM. Then, we characterize the limits of reliable information rates in terms of the maximal achievable outage rates associated to the proposed metric. We also compare our results with the outage rates of a system using a theoretical decoder. Our results are useful for designing a communication system where a prescribed quality of service (QoS), in terms of achievable target rates with small error probability, must be satisfied even in the presence of imperfect channel estimation. Numerical results over both realistic UWB and theoretical Rayleigh fading channels show that the proposed method provides significant gain in terms of BER and outage rates compared to the classical mismatched detector, without introducing any additional complexity.

description: Rydberg chains provide an appealing platform for probing conformal field theories (CFTs) that capture universal behavior in a myriad of physical settings. Focusing on a Rydberg chain at the Ising transition separating charge density wave and disordered phases, we establish a detailed link between microscopics and low-energy physics emerging at criticality. We first construct lattice incarnations of primary fields in the underlying Ising CFT including chiral fermions -- a nontrivial task given that the Rydberg chain Hamiltonian does not admit an exact fermionization. With this dictionary in hand, we compute correlations of microscopic Rydberg operators, paying special attention to finite, open chains of immediate experimental relevance. We further develop a method to quantify how second-neighbor Rydberg interactions tune the sign and strength of four-fermion couplings in the Ising CFT. Finally, we determine how the Ising fields evolve when four-fermion couplings drive an instability to Ising tricriticality. Our results pave the way to a thorough experimental characterization of Ising criticality in Rydberg arrays, and can inform the design of novel higher-dimensional phases based on coupled critical chains.

description: Postpartum depression (PPD) is classified under postpartum psychiatric disorders and initiates soon after birthing, eliciting neuropsychological and behavioral deficits in mothers and offspring. Globally, PPD is estimated to be associated with 130–190 per 1000 birthing. The severity and incidences of PPD have aggravated in the recent years due to the several unfavorable environmental and geopolitical circumstances. The purpose of this systematic review hence is to explore the contributions of recent circumstances on the pathogenesis and incidence of PPD. The search, selection and retrieval of the articles published during the last three years were systematically performed. The results from the primary studies indicate that unfavorable contemporary socio-geopolitical and environmental circumstances (e.g. Covid-19 pandemic, political conflicts/wars, and natural calamities; such as floods and earthquakes) detrimentally affect PPD etiology. A combination of socio-economic and psychological factors, including perceived lack of support and anxiousness about the future may contribute to drastic aggravation of PPD incidences. Finally, we outline some of the potential treatment regimens (e.g. inter-personal psycho- and art-based therapies) that may prove to be effective in amelioration of PPD-linked symptoms in birthing women, either alone or in complementation with traditional pharmacological interventions. We propose these psychological and art-based intervention strategies may beneficially counteract the negative influences of the unfortunate recent events across multiple cultures, societies and geographical regions.

description: We here introduce indicator functions, which identify regions of a given density in order to characterize the density dependence of clustering. After a general introduction to this tool, we show that indicator-function power spectra are biased versions of the linear spectrum on large scales. We provide a calculation from first principles for this bias, we show that it reproduces simulation results, and we provide a simple functional form for the translinear portion of the indicator-function spectra. We also outline two applications: first, these spectra facilitate surgical excision of non-linearity and thus significantly increase the reach of linear theory. Second, indicator-function spectra permit calculation of theoretical covariance matrices for counts-in-cells (CIC), facilitating parameter estimation with complementary CIC methods.

description: As a generalization of Davis-Januszkiewicz theory, there is an essential link between locally standard $(\Z_2)^n$-actions (or $T^n$-actions) actions and nice manifolds with corners, so that a class of nicely behaved equivariant cut-and-paste operations on locally standard actions can be carried out in step on nice manifolds with corners. Based upon this, we investigate what kinds of closed manifolds admit locally standard $(\Z_2)^n$-actions; especially for the 3-dimensional case. Suppose $M$ is an orientable closed connected 3-manifold. When $H_1(M;\Z_2)=0$, it is shown that $M$ admits a locally standard $(\Z_2)^3$-action if and only if $M$ is homeomorphic to a connected sum of 8 copies of some $\Z_2$-homology sphere $N$, and if further assuming $M$ is irreducible, then $M$ must be homeomorphic to $S^3$. In addition, the argument is extended to rational homology 3-sphere $M$ with $H_1(M;\Z_2) \cong \Z_2$ and an additional assumption that the $(\Z_2)^3$-action has a fixed point.

description: To assess experienced stress on different aspects of life and evaluate patient preferences for the consultation of periconception blended lifestyle care, combining face-to-face counseling with eHealth, during the COVID-19 pandemic among (pre)pregnant women. Using this two-fold aim, we were able to analyze the levels of stress among (pre)pregnant women during the COVID-19 pandemic, and to study whether their preferences for the consultation modality of periconception blended lifestyle care was influenced by the levels of stress. A quantitative survey among (pre)pregnant women who received blended periconception lifestyle care between March 2020 and December 2021, from the first until the fourth COVID-19 wave in the Netherlands. The questionnaire used a 5-point Likert scale and measured experienced stress and preferred periconception blended lifestyle care modality. 984 women (response rate: 55.2%) filled out the questionnaire. Experienced stress during the COVID-19 pandemic was relatively low and stable over time. The highest percentage of respondents (31.2%) reported to have experienced stress on fertility and pregnancy. 40.4% (309/764) of the respondents indicated that face-to-face consultations could be replaced by digital consultation. Additionally, the mean experienced stress did not differ between the patients who preferred a video consultation (2.60 ± 1.1), or a telephone consultation (2.57 ± 1.2), either a video or telephone consultation (2.54 ± 1.3), still preferred a face-to-face consultation (2.41 ± 1.4) (p = .83). Our findings indicate willingness for wide implementation of telemedicine within health care delivery, and reorganizing of periconception blended lifestyle care toward personalized and value-based health care.

description: Many women are experiencing postpartum depression (PPD) after giving birth. How to recognize and intervene in high-risk PPD women early and effectively remains unknown. Our objective is to describe the latent trajectory groups of cognitive reactivity (CR) in perinatal women, and their relationship to demographic and disease-related factors, as well as investigate the associations with PPD. Data from 321 perinatal women who were evaluated in urban tertiary hospitals in China at three-time points: 32-35 weeks of pregnancy, 1 week postpartum, and 6 weeks postpartum. Latent class growth modeling was used to identify the trajectory patterns of CR and logistic regression was used to explore the association between demographic and disease-related factors, CR trajectories, and depression. Three trajectory groups were identified: the continuing deterioration group (17.2%), the postpartum deterioration group (22.1%), and the consistent resilient group (60.7%). Participants with a bachelor’s degree or higher and with gestational diabetes diagnosis were more likely to be in the continuing deterioration group. Those who were from only-child families were more likely to be in the postpartum deterioration group. Women in the continuing deterioration group and postpartum deterioration group were more likely to experience PPD. Targeted interventions should be developed based on trajectory group of CR.

description: Hot charge carriers in graphene exhibit fascinating physical phenomena, whose understanding has improved greatly over the past decade. They have distinctly different physical properties compared to, for example, hot carriers in conventional metals. This is predominantly the result of graphene's linear energy-momentum dispersion, its phonon properties, its all-interface character, and the tunability of its carrier density down to very small values, and from electron- to hole-doping. Since a few years, we have witnessed an increasing interest in technological applications enabled by hot carriers in graphene. Of particular interest are optical and optoelectronic applications, where hot carriers are used to detect (photodetection), convert (nonlinear photonics), or emit (luminescence) light. Graphene-enabled systems in these application areas could find widespread use and have a disruptive impact, for example in the field of data communication, high-frequency electronics, and industrial quality control. The aim of this review is to provide an overview of the most relevant physics and working principles that are relevant for applications exploiting hot carriers in graphene.

description: The study of dynamical large deviations allows for a characterization of stationary states of lattice gas models out of equilibrium conditioned on averages of dynamical observables. The application of this framework to the two-dimensional random walk conditioned on partial currents reveals the existence of a dynamical phase transition between delocalized band dynamics and localized vortex dynamics. We present a numerical microscopic characterization of the phases involved, and provide analytical insight based on the macroscopic fluctuation theory. A spectral analysis of the microscopic generator shows that the continuous phase transition is accompanied by spontaneous $\mathbb{Z}_2$-symmetry breaking whereby the stationary solution loses the reflection symmetry of the generator. Dynamical phase transitions similar to this one, which do not rely on exclusion effects or interactions, are likely to be observed in more complex non-equilibrium physics models.

description: LiDAR depth completion is a task that predicts depth values for every pixel on the corresponding camera frame, although only sparse LiDAR points are available. Most of the existing state-of-the-art solutions are based on deep neural networks, which need a large amount of data and heavy computations for training the models. In this letter, a novel non-learning depth completion method is proposed by exploiting the local surface geometry that is enhanced by an outlier removal algorithm. The proposed surface geometry model is inspired by the observation that most pixels with unknown depth have a nearby LiDAR point. Therefore, it is assumed those pixels share the same surface with the nearest LiDAR point, and their respective depth can be estimated as the nearest LiDAR depth value plus a residual error. The residual error is calculated by using a derived equation with several physical parameters as input, including the known camera intrinsic parameters, estimated normal vector, and offset distance on the image plane. The proposed method is further enhanced by an outlier removal algorithm that is designed to remove incorrectly mapped LiDAR points from occluded regions. On KITTI dataset, the proposed solution achieves the best error performance among all existing non-learning methods and is comparable to the best self-supervised learning method and some supervised learning methods. Moreover, since outlier points from occluded regions is a commonly existing problem, the proposed outlier removal algorithm is a general preprocessing step that is applicable to many robotic systems with both camera and LiDAR sensors.

description: A recent group cognitive behavioral therapy (gCBT) intervention for dysmenorrhea conducted by our team demonstrated feasibility, acceptability, and preliminary efficacy at reducing menstrual pain. This study aimed to use qualitative analyses to explore participants’ reflections about the intervention’s group dynamic. Participants included 20 young women ages 18–24 years with average menstrual pain of 8.0 (SD = 1.1) on a 0–10 (0 = none, 10 = worst pain possible) numeric rating scale. Semi-structured individual and group interviews were conducted after the intervention. Researchers then conducted deductive, iterative thematic analysis using a template analysis approach. Two themes were generated: benefit and logistics. The benefit theme included two sub-themes: (1) camaraderie (an emotional, psychological, or social connection between participants); and (2) sharing (information, advice, or experiences). The logistics theme highlighted how the structure of the group influenced the dynamic and was divided into two sub-themes according to the time frame being described: (1) reactions (participants’ experiences with how the group dynamic was facilitated); and (2) future (how the group structure could be improved). Results of this study contribute to the growing body of literature related to gCBT for pain conditions. Future research is needed to optimize the group dynamic and evaluate its specific therapeutic role in the treatment.

description: We study the constraints on reionization from five years of WMAP data, parametrizing the evolution of the average fraction of ionized hydrogen with principal components that provide a complete basis for describing the effects of reionization on large-scale E-mode polarization. Using Markov Chain Monte Carlo methods, we find that the resulting model-independent estimate of the total optical depth is nearly twice as well determined as the estimate from 3-year WMAP data, in agreement with simpler analyses that assume instantaneous reionization. The mean value of the optical depth from principal components is slightly larger than the instantaneous value; we find tau=0.097+/-0.017 using only large-scale polarization, and tau=0.101+/-0.019 when temperature data is included. Likewise, scale invariant n_s=1 spectra are no longer strongly disfavored by WMAP alone. Higher moments of the ionization history show less improvement in the 5-year data than the optical depth. By plotting the distribution of polarization power for models from the MCMC analysis, we show that extracting most of the remaining information about the shape of the reionization history from the CMB requires better measurements of E-mode polarization on scales of l~10-20. Conversely, the quadrupole and octopole polarization power is already predicted to better than cosmic variance given any allowed ionization history at z<30 so that more precise measurements will test the LambdaCDM paradigm.

Reducts of relation algebras: The aspects of axiomatisability and finite representability
Creators: name: Rogozin, Daniel
Publisher: name: arXiv

Subjects: subject: Logic (math.LO)

description: In this paper, we show that the class of representable residuated semigroups has the finite representation property. That is, every finite representable residuated semigroup is representable over a finite base. This result gives a positive solution to Problem 19.17 from the monograph by Hirsch and Hodkinson \cite{hirsch2002relation}. We also show that the class of representable join semilattice-ordered semigroups is pseudo-universal and it has a recursively enumerable axiomatisation. For this purpose, we introduce representability games for join semilattice-ordered semigroups.

Year: 1998

description: Eine umweltverträgliche Tierhaltung ist gekennzeichnet durch emissionsarme Verfahren der Entmistung, Lagerung und Ausbringung der Gülle. Mit dem Ansäuern der Gülle kommt es zur pH-Wert-Verschiebung und als Folge zu geringeren Schadgasemissionen. Stand bisher Ammoniak (NH3) im Vordergrund der Betrachtung, richten sich neuere Untersuchungen auch auf Methan (CH4) und Distickstoffmonoxid (N20). Im Vergleich zu Salpetersäure wurde Milchsäure eingesetzt. Dabei stellt sich die Güllebehandlung mit Milchsäure vorteilhafter dar. Neben der Erhöhung der Arbeitssicherheit wird eine beträchtliche Reduzierung der Emissionen von NH3, CH4 und N20 erreicht.

description: This pilot study investigated the feasibility of postpartum Eye Movement Desensitization and Reprocessing (EMDR) for improving posttraumatic stress disorder (PTSD) symptoms, and its association with work absence, relationship difficulties, and development of psychiatric disorders in women with a traumatic childbirth experience who do not meet all criteria for PTSD. A randomized controlled study was conducted among 20 women (EMDR (N=11) vs. care as usual (CAU) (N=9)) who reported a traumatic birth. Outcomes were measured by questionnaires and a semi-structured interview. The results showed improvement of trauma-related psychological complaints for all women. EMDR appears to be more effective in reducing PTSD symptoms than CAU. Moreover, EMDR showed a small positive effect on work absence due to factors related to the traumatic childbirth experience. Results from the questionnaires were substantiated by interviews. However, due to the small size of the study, no statistically significant differences were found. In addition, no differences were found for relationship difficulties and development of psychiatric disorders. In conclusion, women with a traumatic birth experience may benefit from EMDR, even if they do not qualify for a diagnosis of PTSD. This study could be a starting point for future research aimed at early treatment that reduces trauma-related psychological complaints in postpartum women.
Transport and Quantum Walk of Nonclassical Light in Coupled Waveguides

description: We study the transport and quantum walk of nonclassical light in an array of coupled waveguides which have novel properties like very low decoherence and thus making them ideal for storage of quantum information. We show how squeezing gets turned over from one waveguide to another. We further show how input nonclassical light can generate entanglement among different waveguides. Our results involve both first quantization due to array structure and second quantization due to the quantum nature of fields and can also be used to discuss the Talbot effect in the quantum regime.

Bestimmung der Energieausnutzung in der Pflanzenproduktion

Year: 1998

description: Energetische Kennzahlen erlauben Aussagen zur Bewirtschaftungsintensität und zu Umweltwirkungen der Landwirtschaft. Zur Bewertung des Energiehaushaltes in Landwirtschaftsbetrieben sind Indikatoren und Zielwerte erforderlich. ln der Pflanzenproduktion eignen sich hierfür der Energieeinsatz sowie Kenngrößen der Energieausnutzung. Da ein möglichst geringer Energieeinsatz für die Produktion von Nahrungsmitteln und Rohstoffen volkswirtschaftlich sinnvoll ist, wurde als Indikator der Energieausnutzung die Energieintensität Verhältnis aus Energieeinsatz und Produktmenge in Getreideeinheiten gewählt. Zur Ableitung energetischer Kennzahlen in der Pflanzenproduktion werden Dauerfeldversuche ausgewertet. Ausgehend vom Anbauverhältnis kann mit standort- und fruchtartenbezogenen Zielwerten ein betrieblicher Zielwert errechnet werden.

description: We investigate the integer quantum Hall system in a two dimensional lattice model with spatially correlated disorder by using the efficient method to calculate the Chern number proposed by Fukui \textit{et al}. Distribution of charge density indicates that the extended states at the center of each Landau band have percolating current paths, which are topologically equivalent to the edge states that exist in a system with boundaries. As increasing the strength of disorder, floating feature is observed in an averaged Hall conductance as a function of filling factor. Its relation to the observed experiments is also discussed.
On Optimal Turbo Decoding of Wideband MIMO-OFDM Systems Under Imperfect Channel State Information

description: We consider the decoding of bit interleaved coded modulation (BICM) applied to both multiband and MIMO OFDM systems for typical scenarios where only a noisy (possibly very bad) estimate of the channel is provided by sending a limited number of pilot symbols. First, by using a Bayesian framework involving the channel a posteriori density, we adopt a practical decoding metric that is robust to the presence of channel estimation errors. Then this metric is used in the demapping part of BICM multiband and MIMO OFDM receivers. We also compare our results with the performance of a mismatched decoder that replaces the channel by its estimate in the decoding metric. Numerical results over both realistic UWB and theoretical Rayleigh fading channels show that the proposed method provides significant gain in terms of bit error rate compared to the classical mismatched detector, without introducing any additional complexity.

description: Computational micromagnetics has become an essential tool in academia and industry to support fundamental research and the design and development of devices. Consequently, computational micromagnetics is widely used in the community, and the fraction of time researchers spend performing computational studies is growing. We focus on reducing this time by improving the interface between the numerical simulation and the researcher. We have designed and developed a human-centred research environment called Ubermag. With Ubermag, scientists can control an existing micromagnetic simulation package, such as OOMMF, from Jupyter notebooks. The complete simulation workflow, including definition, execution, and data analysis of simulation runs, can be performed within the same notebook environment. Numerical libraries, co-developed by the computational and data science community, can immediately be used for micromagnetic data analysis within this Python-based environment. By design, it is possible to extend Ubermag to drive other micromagnetic packages from the same environment.

description: We review our recent analysis of pion-pion scattering data in terms of Roy equations and Forward Dispersion Relations, and present some preliminary results in terms of a new set of once-subtracted coupled equations for partial waves. The first analysis consists of independent fits to the different pion-pion channels that satisfies rather well the dispersive representation. In the second analysis we constrain the fit with the dispersion relations. The latter provides a very precise and model independent description of data using just analyticity, causality and crossing.

description: Consider a branching random walk, where the branching mechanism is governed by a Galton-Watson process, and the migration by a finite range symmetric irreducible random walk on the integer lattice $\mathbb{Z}^d$. Let $Z_n(z)$ be the number of the particles in the $n$-th generation at the point $z\in \mathbb{Z}^d$. Under the mild moment conditions for offspring distribution of the underlying Galton-Watson, we derive a second order expansion in the local limit theorem for $Z_n(z)$ for each given $z\in \mathbb{Z}^d$. That generalizes the results for simple branching random walks obtained by Gao [2018, SPA].
