description: Auf einen Blick...
• Die vorgezogenen Renten sind rückläufig, und die Regelaltersrente mit 65 wird wieder häufiger in Anspruch genommen. Bis 2001 ist das nur ein "demographischer Nachhall“ starker Geburtsjahrgänge, deren größere Teile bereits in den Jahren zuvor in vorgezogene Renten gegangen sind. Ab 2002 / 2003 ist jedoch eine echte Trendwende zurück zur Rente mit 65 erkennbar. 
• Die gleitende Heraufsetzung der Altersgrenzen für vorgezogene Renten ohne Abschlag zeigt noch eine weitere Wirkung: Die Zugänge in vorgezogene Altersrenten verschieben sich vom frühestmöglichen Lebensjahr der Inanspruchnahme (60 bzw. 63) in die jeweils folgenden Altersstufen (61 bis 63 bzw. 64).
• Im Ergebnis ist das durchschnittliche Rentenzugangsalter für Zugänge zwischen 50 und 69 Jahren von 1996 bis 2003 um 12 Monate angestiegen. Das ist nicht nur auf die spätere Inanspruchnahme von Altersrenten, sondern auch auf geringere Eintritte von Älteren in Erwerbsminderungsrenten zurückzuführen.
• In den neuen Bundesländern dominieren nach wie vor die vorgezogenen Renten. Dieses ist einerseits ein Spiegelbild der ungünstigen Arbeitsmarktsituation, andererseits ein Ergebnis der höheren Erwerbsbeteiligung der Frauen: Ostdeutsche Frauen erfüllen häufiger als westdeutsche die Voraussetzungen für die Frauenaltersrente ab 60.
• In ganz Deutschland ist für Frauen die Frauenaltersrente nach wie vor die häufigste, wenn auch rückläufige Rentenart.
• Spätere Renteneintritte sind nicht mit längerer Erwerbstätigkeit gleichzusetzen. Ebenso gut könnten die Überbrückungszeiträume zwischen Erwerbsaustritt und Renteneintritt länger werden. Zu denken ist hier an Arbeitslosigkeit, an „Leistungsbezug unter erleichterten Voraussetzungen“ oder an Nichterwerbstätigkeit. – Diese Problematik muss künftigen Reports vorbehalten bleiben.

description: The magnetically ordered states of the A-site ordered perovskite manganites LaBaMn2O6 and YBaMn2O6 have been investigated by muon spin relaxation in zero external magnetic field. Our data reveal striking differences in the nature of the magnetically ordered state of these materials. For LaBaMn2O6, the muSR time-spectra in the ferromagnetic state below ~ 330 K reveal a strongly inhomogeneous phase, reminiscent of a Griffiths phase. Within this magnetically inhomogeneous phase, an antiferromagnetic state develops below 150 K, which displays well defined static internal magnetic fields, but reaches only 30% of the volume fraction at low temperatures. A broad distribution of muSR relaxation rates is inferred down to the lowest temperatures. This behavior is similar to the A-site disordered La0.5Ba0.5MnO3. On the other hand, for YBaMn2O6, the muSR time spectra for both (i) the charge and orbital ordered and (ii) the paramagnetic phases reveal rather homogeneous states, namely, an exponential relaxation in the paramagnetic state and well defined muon spin oscillation in the antiferromagnetic state.

description: The research for this master’s thesis is based in the field of text semiotics, but also draws on the methodological framework of the genetic trajectory (parcours génératif) developed by linguist and semiologist Algirdas Julien Greimas is adopted for specific research purposes. The aim of the study is to investigate the concept of “disease” in the literary text titled Kerenia κoukla by K. Christomanos by employing a pilot study in Computer-Assisted Text Analysis using software Voyant Tools based in interpretive discourse analysis methodology, which emphasizes corpus editing tools derived from Corpus Linguistics with application, among other fields, to Digital Humanities. The corpus-driven lexico-metric analysis is applied to explore linguistic shapes and patterns depicted in the literary text for contextualizing the “disease”. In the next stage, the narrative program of the “disease”, its representation and textual realization are studied, quantitatively and qualitatively, through contextual tables (concordances). On a second level, by using these tables, the research reveals “isotopies” for the level of expression as well as for the connotative value of the “disease”.
Interface-resolved DNS of vertical particulate channel flow in the turbulent regime

Subjects: subject: Fluid Dynamics (physics.flu-dyn)
subject: FOS: Physical sciences

description: We have conducted a direct numerical simulation (DNS) study of dilute turbulent particulate flow in a vertical plane channel, considering thousands of finite-size rigid particles with resolved phase interfaces. The particle diameter corresponds to approximately 11 wall units and their terminal Reynolds number is set to 136. The fluid flow with bulk Reynolds number 2700 is directed upward, which maintains the particles suspended upon average. Two density ratios were simulated, differing by a factor of 4.5. The corresponding Stokes numbers of the two flow cases were O(10) in the near-wall region and O(1) in the outer flow. We have observed the formation of large-scale elongated streak-like structures with streamwise dimensions of the order of 8 channel half-widths and cross-stream dimensions of the order of one half-width. At the same time, we have found no evidence of significant formation of particle clusters, which suggests that the large structures are due to an intrinsic instability of the flow, triggered by the presence of the particles. It was found that the mean fluid velocity profile tends towards a concave shape, and the turbulence intensity as well as the normal stress anisotropy are strongly increased. The effect of varying the Stokes number while maintaining the buoyancy, particle size and volume fraction constant was relatively weak.

Publisher: name: SAGE Publications
Year: 2023

description:
As age at first birth continues to increase in the United States, the use of medically assisted reproduction (MAR) has likely increased. Using population-level data of births in the United States from the National Vital Statistics System from 2010 to 2021, the authors document the proportion of births due to MAR with a focus on parents 40 years or older, disaggregating by parental age combinations and parity. Although MAR-related births constitute a small proportion of all births, there is a growing and sizable proportion of first births to women 40 years or older due to MAR. Specifically, 28.2 percent, 21.5 percent, and 15.3 percent first births involved MAR among mothers 40 or older with an unknown father’s age, both parents 40 or older, and mothers 40 or older with fathers younger than 40, respectively. Thus, for some groups, MAR is a particularly important component of the pathway to parenthood.
Integration of vision and force sensors for grasping

description: This paper describes a set of methods that can be used to integrate real-time external vision sensing with internal force and position sensing to estimate contact forces by the fingers of a hand. Estimating these forces and contacts is essential to performing dextrous manipulation tasks. Most robotic hands are either sensorless or lack the ability to accurately and robustly report position and force information relating to contact. By adding external vision sensing, we can complement any internal sensors to more accurately estimate forces and contact positions. Experiments are described that use real-time visual trackers in conjunction with internal strain gauges and a new tactile sensor to accurately estimate finger contacts and applied forces for a three fingered robotic hand.
Barriers and facilitators to hearing aid uptake in older females : a qualitative report
Creators: name: Winsor, Danielle Andrea
Publisher: name: University of British Columbia
Year: 2011

description: Although hearing loss is one of the most prevalent chronic conditions among older adults in Canada, affecting more than 30% of the population over the age of 65 (Public Health Agency of Canada, 2006), it is surprising that only 15% to 25% of people with hearing loss actually use hearing assistive technology such as hearing aids (Cohen-Mansfield & Taylor, 2004a; Edwards & Jones, 1998; Gilhome Herbst, Meredith, & Stephens, 1991). A review by Jenstad and Moon (2011) of the literature on barriers and facilitators to hearing aid use reported 7 types of barriers and/or facilitators: effects of hearing loss on quality of life, cost, personality/psychological factors, stigma, degree of hearing loss, age, and gender. The purpose of the current study was to use qualitative methods to further investigate the facilitators and barriers to hearing aid uptake as reported by females with age-related hearing loss. Nine women between 60 and 75 years of age and diagnosed with hearing loss were interviewed, five of whom had decided to get hearing aids while the remaining four had not. Through semi-structured interviews analyzed thematically, the overarching theme identified was dynamism. Dynamism is the interplay of factors that influence each individual’s decision regarding hearing aid uptake. Within the overarching theme of dynamism, 4 themes were identified: self-perceived hearing, information gathering and informed decision making, influence of others, and associated cost. Specific clinical applications of the results include: the provision of unbiased sources of information regarding hearing and hearing loss, careful word choice of the clinician, and the need for rapport between the clinician and client. The results of this study underscore the need for qualitative research on hearing aid uptake in males and in other age groups, as well as the need for further examination of the impact of information gathering and the influence of others on hearing aid uptake.

description: Most robotic hands are either sensorless or lack the ability to accurately and robustly report position and force information relating to contact. This paper describes a robotic hand system that uses a limited set of native-joint position and force sensing along with custom-designed tactile sensors and real-time vision modules to accurately compute finger contacts and applied forces for grasping tasks. Three experiments are described: integration of real-time visual trackers in conjunction with internal strain gauge sensing to correctly localize and compute finger forces, determination of contact points on the inner and outer links of a finger through tactile sensing and visual sensing, and determination of vertical displacement by tactile sensing for a grasping task.

In the case of the electric and magnetic form factors, the level of agreement between theory and experiment is very satisfactory and gives us considerable confidence in our capacity to make reliable calculations within non-perturbative QCD. In view of the importance of the scalar form factors to the detection of dark matter candidates such as neutralinos, we place a particular emphasis on the determination of the pi-N and strange quark sigma commutators.

Synergy of anti-leukemic effects between anti-thymocyte globulin, busulfan, and fludarabine

description: Antithymocyte Globulin (ATG) is an anti-GvHD (Graft versus Host Disease) drug that has recently been shown to have anti-leukemic effects. In Alberta, Busulfan and Fludarabine are used to treat acute myeloid leukemia. However, both drugs also lead to the death of healthy cells within the body, especially with increased doses. It would be beneficial to study ways to maintain their effects while decreasing their toxicity, such as synergy with ATG. Different concentrations of ATG were combined with different concentrations of Busulfan and Fludarabine separately to test their effects on pre-conditioned leukemia cell samples from acute myeloid leukemia patients. Cell death was quantified using flow cytometry. The cells from five patients were used and combined into graphs that compared cells dyed by 7AAD (dead cells) between the drugs. In some of the combinations, there appeared to be increased cell death in test tubes with a combination of ATG with Busulfan or ATG with Fludarabine. However, with the use of the Wilcoxon Matched Pairs Test, the difference was deemed not significant. Even though there were no significant differences, it could be due to the low sample size. Furthermore, other concentrations not tested in this experiment could yield better results. If synergy exists between ATG and Busulfan or Fludarabine, the two drugs should be moved up in patients’ conditioning schedules to allow synergism to occur, leading to more cancer cell death with less risk for side effects.

The effects of magnetic field, single-ion anisotropy, and biquadratic interactions are investigated using linear spin wave theory with spins in a canted basis about the Type IIA FCC antiferromagnetic ground state structure which is known to be stable. We calculate the expected finite frequency neutron scattering intensity and give qualitative criteria for typical FCC materials MnO and CoO. The magnetization reduction due to quantum zero point fluctuations is also analyzed.

Determining targeting specificity of nuclearly encoded organelle proteins

Subjects: subject: 570

description: Pflanzenzellen tragen zwei Organellen endosymbiotischen Ursprungs, Mitochondrien und Chloroplasten (Plastiden). Die meisten ihrer Proteine sind im Zellkern codiert und müssen deshalb nach ihrer Synthese im Cytosol in das jeweilige Zielorganell "zurück"transportiert werden. In der Regel erfolgt dieser Transport monospezifisch, d.h. nur in eines dieser Organellen. Allerdings konnten in den letzten Jahren einige Proteine identifiziert werden, die "mehrdeutige" Transitpeptide für den Transport sowohl in die Mitochondrien als auch in die Plastiden tragen. Ein solches dual targeting ist jedoch häufig umstritten, zum einen wegen der oftmals unklaren Funktion des Proteins in einem der Organellen, zum anderen wegen divergenter Ergebnisse bei Verwendung mehrerer experimenteller Ansätze. Deshalb sollten in dieser Arbeit vier häufig genutzte in vivo-Ansätze zur subzellulären Proteinlokalisierung systematisch miteinander verglichen werden. Außerdem wurde hier erstmals eine in vivo-Methode auf Pflanzenzellen angewendet, die auf spontan assemblierenden Teilen eines Fluoreszenzproteins (self assembling split-FP) beruht.
description: The uniqueness of plant cells is marked by the presence of two organelles of endosymbiotic origin, namely mitochondria and plastids. Most of the organelle proteins are encoded in the nucleus, synthesized in the cytosol and need to be “re”-transported into the respective target organelle. While transport is in most instances strictly monospecific, a group of proteins carries “ambiguous” transit peptides mediating transport into both, mitochondria and plastids (dual targeting). A number of different approaches including in organello and in vivo assays are established to determine the targeting specificity of such transit peptides. Due to variability in the results obtained from different experimental approaches, such dual targeting is often disputed particularly in those instances where the function of these proteins is enigmatic in one or the other organelle. In this work, four in vivo approaches based on fluorescent protein (FP) tagging were systematically analyzed. Furthermore, a novel self-assembling splitfluorescent protein-based approach was established to circumvent some of the inherent drawbacks of the ‘standard’ FP-based approaches.

Detecting Music in Ambient Audio by Long-Window Autocorrelation

description: We address the problem of detecting music in the background of ambient real-world audio recordings such as the sound track of consumer-shot video. Such material may contain high levels of noises, and we seek to devise features that will reveal music content in such circumstances. Sustained, steady musical pitches show significant, structured autocorrelation at when calculated over windows of hundreds of milliseconds, where autocorrelation of aperiodic noise has become negligible at higher-lag points if a signal is whitened by LPC. Using such features, further compensated by their long-term average to remove the effect of stationary periodic noise, we produce GMM and SVM based classifiers with high performance compared with previous approaches, as verified on a corpus of real consumer video.

A sensitivity analysis at the optimal solution has revealed the importance of states at large deformations in driving the parameterization of the functional. The good agreement with experimental data on masses and separation energies, achieved with the previous parameterization UNEDF0, is largely preserved. In addition, the new energy density UNEDF1 gives a much improved description of the fission barriers in 240Pu and neighboring nuclei.

3-D modeling from range imagery: an incremental method with a planning component

Publisher: name: Columbia University
Year: 1997

description: In this paper we present a method for automatically constructing a CAD model of an unknown object from range images. The method is an incremental one that interleaves a sensing operation that acquires and merges information into the model with a planning phase to determine the next sensor position or "view". This is accomplished by integrating a system for 3-D model acquisition with a sensor planner. The model acquisition system provides facilities for range image acquisition, solid model construction and model merging: both mesh surface and solid representations are used to build a model of the range data from each view, which is then merged with the model built from previous sensing operations. The planning system utilizes the resulting incomplete model to plan the next sensing operation by finding a sensor viewpoint that will improve the fidelity of the model. Experimental results are presented for a complex part that includes polygonal faces, curved surfaces, and large self-occlusions.

BACKGROUND: Peripheral artery disease (PAD) is associated with lower physical activity but less is known about its association with daily patterns of activity. We examined the cross-sectional association between ankle-brachial index (ABI) and objectively measured patterns of physical activity among Hispanic/Latino adults. METHODS: We analyzed data from 7 688 participants (aged 45-74 years) in the Hispanic Community Health Study/Study of Latinos. ABI was categorized as low (≤0.90, indicating PAD), borderline low (0.91-0.99), normal (1.00-1.40), and high (>1.40, indicating incompressible ankle arteries). Daily physical activity metrics derived from accelerometer data included: log of total activity counts (LTAC), total log-transformed activity counts (TLAC), and active-to-sedentary transition probability (ASTP). Average differences between ABI categories in physical activity, overall and by 4-hour time-of-day intervals, were assessed using linear regression and mixed-effects models, respectively. RESULTS: In Hispanic/Latino adults, 5.3% and 2.6% had low and high ABIs, respectively. After adjustment, having a low compared to a normal ABI was associated with lower volume (LTAC = -0.13, p < .01; TLAC = -74.4, p = .04) and more fragmented physical activity (ASTP = 1.22%, p < .01). Having a low ABI was linked with more fragmented physical activity after 12 pm (p < .01). Having a high ABI was associated with lower volumes of activity (TLAC = -132.0, p = .03). CONCLUSIONS: Having a low or high ABI is associated with lower and more fragmented physical activity in Hispanic/Latino adults. In adults with low ABI, physical activity is more fragmented in the afternoon to evening. Longitudinal research is warranted to expand these findings to guide targeted interventions for PAD or incompressible ankle arteries.

description: This paper presents a novel method for identifying regions of speech in the kinds of energetic and highly-variable noise present in 'personal audio' collected by body-worn continuous recorders. Motivated by psychoacoustic evidence that pitch is crucial in the perception and organization of sound, we use a noise-robust pitch detection algorithm to locate speech-like regions. To avoid false alarms resulting from background noise with strong periodic components (such as air-conditioning), we add a new channel selection scheme to suppress frequency subbands where the autocorrelation is more stationary than encountered in voiced speech. Quantitative evaluation shows that these harmonic noises are effectively removed by this compensation technique in the domain of autocorrelogram, and that detection performance is significantly better than existing algorithms for detecting the presence of speech in real-world personal audio recordings.

The Case for Reparative and Transformative Justice Approaches to Sexual Violence in Canada: A Proposal to Pilot and Test New Approaches.
Creators: name: Boutilier, Sophia
name: Wells, Lana
Publisher: name: Social Work
Year: 2018

description: The intention of writing this case and proposal is in response to the highly-visible #MeToo and #TimesUp movements that have provided an opportunity to think about processes for healing from sexual violence and social change. Sexual abusers and harassers are being called out, but where do they go? Where do the victims of sexual violence go if they do not want to pursue a traditional justice response? At Shift, we believe that we need to be working on strategies and initiatives that create hope, healing, and opportunities to transform gender relations and norms. We hope this case will inspire and rally key leaders in communities, government, advocacy, and justice to design, fund, pilot, and evaluate non-mandated programs outside of the criminal justice system. We call for a non-mandated model that integrates restorative, reparative, and transformative principles to respond to sexual violence. We believe that this approach has the potential to meet victims’ needs, rehabilitate offenders, address injustice, and prevent future acts of violence.

Abstract Despite the availability of effective vaccines and a recent decrease in annual deaths, coronavirus disease-2019 (COVID-19) remains a leading cause of death. Serological studies provide insights into host immunobiology of adaptive immune response to infection, which holds promise for identifying high-risk individuals for adverse COVID-19 outcomes. We investigated correlates of anti-nucleocapsid (N) antibody responses following Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) infection in a U.S. population-based meta-cohort of adults participating in longstanding NIH-funded cohort studies. Anti-nucleocapsid antibodies were measured from dried blood spots collected between February 2021-February 2023. Among 1419 Collaborative Cohort of Cohorts for COVID-19 Research (C4R) participants with prior SARS-CoV-2 infection, the mean age (standard deviation) was 65.8(12.1), 61% were women, and 42.8% self-reported membership in a race/ethnicity minority group. The proportion of participants reactive to nucleocapsid peaked at 69% by 4 months post-infection and waned to only 44% ≥12 months after infection. Higher anti-nucleocapsid antibody response was associated with older age, Hispanic or American Indian Alaskan Native (vs. white) race/ethnicity, lower income, lower education, former smoking and higher anti-spike antibody levels. Asian race (vs. white) and vaccination (even after infection) were associated with lower nucleocapsid reactivity. Neither vaccine manufacturer nor common cardiometabolic co-morbidities were not associated with anti-nucleocapsid response. These findings inform the underlying immunobiology of adaptive immune response to infection, as well as the potential utility of anti-nucleocapsid antibody response for clinical practice and COVID-19 serosurveillance.

description: We study semi-infinite paths of the radial spanning tree (RST) of a Poisson point process in the plane. We first show that the expectation of the number of intersection points between semi-infinite paths and the sphere with radius $r$ grows sublinearly with $r$. Then, we prove that in each (deterministic) direction, there exists with probability one a unique semi-infinite path, framed by an infinite number of other semi-infinite paths of close asymptotic directions. The set of (random) directions in which there are more than one semi-infinite paths is dense in $[0,2π)$. It corresponds to possible asymptotic directions of competition interfaces. We show that the RST can be decomposed in at most five infinite subtrees directly connected to the root. The interfaces separating these subtrees are studied and simulations are provided.

description: The current thesis is about the ethnoarchaeological research in Greece in the 21st century. Case studies that took place in Greece but also in countries outside of Greece during the 20th and 21st have been chosen in order to present and highlight the evolution of the science as well as its contribution to the science of archaeology. Through the selected ethnoarchaeological case studies it is sought to make a comparison and to project the evaluation of the methodologies between the researches that took place in Greece during the 20th and 21st centuries, using researches that deal with issues related to animal husbandry activities, surviving strategies, the management of material remains as well as a geoethnoarchaeological example that is related to the construction of traditional farmsteads in the islands of Naxos and Kato Koufonisi.

description: Detecting the time of occurrence of an acoustic event (for instance, a cheer) embedded in a longer soundtrack is useful and important for applications such as search and retrieval in consumer video archives. We present a Markov-model based clustering algorithm able to identify and segment consistent sets of temporal frames into regions associated with different ground-truth labels, and simultaneously to exclude a set of uninformative frames shared in common from all clips. The labels are provided at the clip level, so this refinement of the time axis represents a variant of Multiple-Instance Learning (MIL). Evaluation shows that local concepts are effectively detected by this clustering technique based on coarse-scale labels, and that detection performance is significantly better than existing algorithms for classifying real-world consumer recordings.
Computing robust viewpoints with multi-constraints using tree annealing

description: In order to compute camera viewpoints during sensor planning, Tarabanis et al. (1991) present a group of feature detectability constraints which include six nonlinear inequalities in an eight-dimensional real space. It is difficult to compute robust viewpoints which satisfy all feature detectability constraints. In this paper, the viewpoint setting is formulated as an unconstrained optimization problem. Then a tree annealing algorithm, which is a general-purpose technique for finding minima of functions of continuously-valued variables, is applied to solve this nonlinear multiconstraint optimization problem. Our results show that the technique is quite effective to get robust viewpoints even in the presence of considerable amounts of noise.

description: One possibility for avoiding constraint violation in numerical relativity simulations adopting free-evolution schemes is to modify the continuum evolution equations so that constraint violations are damped away. Gundlach et. al. demonstrated that such a scheme damps low amplitude, high frequency constraint violating modes exponentially for the Z4 formulation of General Relativity. Here we analyze the effect of the damping scheme in numerical applications on a conformal decomposition of Z4. After reproducing the theoretically predicted damping rates of constraint violations in the linear regime, we explore numerical solutions not covered by the theoretical analysis. In particular we examine the effect of the damping scheme on low-frequency and on high-amplitude perturbations of flat spacetime as well and on the long-term dynamics of puncture and compact star initial data in the context of spherical symmetry. We find that the damping scheme is effective provided that the constraint violation is resolved on the numerical grid. On grid noise the combination of artificial dissipation and damping helps to suppress constraint violations. We find that care must be taken in choosing the damping parameter in simulations of puncture black holes. Otherwise the damping scheme can cause undesirable growth of the constraints, and even qualitatively incorrect evolutions. In the numerical evolution of a compact static star we find that the choice of the damping parameter is even more delicate, but may lead to a small decrease of constraint violation. For a large range of values it results in unphysical behavior.

description: Auf einen Blick... 
•Eintritte in vorgezogene Altersrenten haben sich in den letzten Jahren vom frühestmöglichen Lebensjahr der Inanspruchnahme (60 bzw. 63) zunehmend auf spätere Lebensjahre verschoben. Die Versicherten reagierten damit auf die gleitende Heraufsetzung der Altersgrenzen, ab denen diese Renten noch abschlagsfrei zu haben waren.
•Seit 2003 wird auch die Regelaltersrente (65 Jahre) wieder stärker in Anspruch genommen. Das unterstreicht den Trend: Renteneintritte erfolgen später, um Rentenminderungen durch Abschläge zu vermeiden bzw. zu minimieren.
•Insbesondere Männer verlagern ihren Rentenbeginn auf spätere Lebensjahre. Bei den Frauen kam es bisher überwiegend nur zu einer Verschiebung vom 60. auf das 61. Lebensjahr. 
•Die Heraufsetzung der Altersgrenzen erfolgt bei den einzelnen Rentenarten zeitlich unterschiedlich. Soweit sie die Voraussetzungen erfüllen, wichen Versicherte deshalb von einer Rentenart auf eine andere aus. 
•Arbeitslose Frauen nutzten nunmehr fast ausschließlich die Frauenaltersrente statt der Rente wegen Arbeitslosigkeit. Zunehmenden Zugänge in die Schwerbehindertenrente stand eine abnehmende Inanspruchnahme von Erwerbsminderungsrenten durch Ältere gegenüber.
