Browsing a digital library: a new approach for the New Zealand Digital Library
Creators: name: McKay, Dana
name: Cunningham, Sally Jo
Publisher: name: Swinburne
Year: 2024

description: Browsing is part of the information seeking process, used when information needs are ill-defined or unspecific. Browsing and searching are often interleaved during information seeking to accommodate changing awareness of information needs. Digital Libraries often support full-text search, but are not so helpful in supporting browsing. Described here is a novel browsing system created for the Greenstone software used by the New Zealand Digital Library that supports users in a more natural approach to the information seeking process.

Subjects: subject: Engineering, Electronics and Electrical.

description: In this thesis, image and video processing algorithms, especially the compression algorithms, are first studied in their natural formats to appreciate the needs for real-time operations and hence, parallel computing. The computational intense, memory-bound problems are next approached from two directions: algorithmic and architectural. Algorithmic approach tends to systematically analyze the flow independence and data independence of a program, while architectural approach tends to gain speed-up by resource multiplicity and time sharing. The majority of image and video processing algorithms are inherently data-parallel in nature. The vectorization of these algorithms requires consistent practices, and new challenge in parallel programming seems endless. The data-parallel nature of image/video processing algorithms map well onto the Single-Instruction stream, Multiple-Data stream (SIMD) of an increasingly popular Memory-Embedded Array Processor classified as the Intelligent RAMS, specifically, the Computational*RAM (C*RAM). C*RAM is a SIMD-memory hybrid where the processing elements are pitch-matched to memory columns of a conventional computer RAM at the sense-amplifiers to take advantage of the inherently high memory bandwidth, and the emulation of the massively parallel processors. Throughout the thesis, speed-ups from 1 to 3 orders of magnitude are obtained. Memory-bound algorithms such as Motion Estimation, and Mean-Absolute-Error for Nearest Neighbor Distortion Computation are among the most efficient implementations. At its best, this thesis will, definitely, put forward the promising research direction which involves fast and efficient in-memory parallel computing for visual communications.

description: Strip cutting, from its form and dimension, may be called a landscape element; it is also a disturbance which brings about sudden changes in the resources of the natural environment, particularly in forest vegetation. Therefore, the purpose of this thesis is to determine the spatial variation (in vertical stratification and horizontal structure) of deciduous forest vegetation in three strip corridors of variable widths (30, 60 and 90 metres). To this effect, quantitative measures of composition and specific diversity have been taken, as well as other measures of variables closely related to vegetation. The use of factorial methods (correspondence analysis, grouping method) completes the information gathered on vegetation dynamism in strip corridors. The results of this study indicate that the width of the corridor has, to a certain extent, a structuring effect on composition and specific diversity, and has an influence on the succession pattern. All three strip corridors are sufficiently regenerated, and the 30 metre corridor shows the highest specific diversity. The subject is dealt with in terms of both forest regeneration conditions and landscape ecology, since the effect of corridor width on secondary vegetation dynamism is studied.

description: The primary difficulty in measuring dynamical masses of galaxy clusters from galaxy data lies in the separation between true cluster members from interloping galaxies along the line of sight.We study the impact of membership contamination and incompleteness on cluster mass estimates obtained with 25 commonly used techniques applied to nearly 1000 mock clusters with precise spectroscopic redshifts. We show that all methods overestimate or underestimate cluster masses when applied to contaminated or incomplete galaxy samples, respectively. This appears to be the main source of the intrinsic scatter in the mass scaling relation. Applying corrections based on a prior knowledge of contamination and incompleteness can reduce the scatter to the level of shot noise expected for poorly sampled clusters.We establish an empirical model quantifying the effect of imperfect membership on cluster mass estimation and discuss its universal and method-dependent features.We find that both imperfect membership and the response of the mass estimators depend on cluster mass, effectively causing a flattening of the estimated-true mass relation. Imperfect membership thus alters cluster counts determined from spectroscopic surveys, hence the cosmological parameters that depend on such counts.

description: The EU Nature Restoration Law (NRL) is critical for the restoration of degraded ecosystems and active afforestation of degraded peatlands has been suggested as a restoration measure under the NRL. Here, we discuss the current state of scientific evidence on the climate mitigation effects of peatlands under forestry. Afforestation of drained peatlands without restoring their hydrology does not fully restore ecosystem functions. Evidence on long-term climate benefits is lacking and it is unclear whether CO2 sequestration of forest on drained peatland can offset the carbon loss from the peat over the long-term. While afforestation may offer short-term gains in certain cases, it compromises the sustainability of peatland carbon storage. Thus, active afforestation of drained peatlands is not a viable option for climate mitigation under the EU Nature Restoration Law and might even impede future rewetting/restoration efforts. Instead, restoring hydrological conditions through rewetting is crucial for effective peatland restoration.

description: La presente recherche a pour but d'analyser le developpement de la regle de position des pronoms clitiques objets en francais langue seconde acquis par une population adulte. Le cadre d'analyse adopte est le modele multi-dimensionnel dans sa version la plus recente proposee par Manfred Pienemann. Les postulats defendus par le modele fondent l'universalite de certaines regles syntaxiques de l'interlangue sur un ensemble de contraintes psycholinguistiques, essentiellement cognitives plutot que formelles. Une etude longitudinale courte, constituee de trois series de tests administres a des intervalles reguliers, a permis de recueillir pendant une periode de 16 semaines les productions orales et ecrites d'un groupe d'apprenants adultes. Trois tests distincts ont ete utilises a chaques etape de l'etude: un test de closure, un test ecrit de debrouillement de phrases contenant un pronom clitique objet, et un test de traduction orale dont les phrases stimulus anglaises sont identiques aux phrases cibles du test de debrouillement correspondant. Une correlation relativement elevee a ete observee entre les tests de debrouillement et ceux de traduction utilises pour les deux dernieres series de tests. (Abstract shortened by UMI.)
Erotic depictions on a selection of fourteen Attic sixth-century black-figure vases found in Etruscan tombs.

Subjects: subject: Art History.

description: The subject of this Thesis is "Erotica on a Selection of Fourteen Attic Sixth-Century Black-Figure Vases Found in Etruscan Tombs". The first chapter provides an introduction to the subject. It discusses the evidence to be examined in the thesis, and briefly reviews the secondary literature on the subject. It then outlines the method followed in researching the thesis. Finally, it gives a summary of the basic techniques of Attic black-figure pottery. The second chapter is a detailed descriptive catalogue of fourteen vases with human copulation scenes. Details are given of each figure painted on the vases, and all subsidiary decoration. Both homoerotic and heterosexual copulations are shown. The third chapter is a discussion of the data revealed by the detailed catalogue. It examines copulation positions, Dionysian iconography, the komos, symposion and banquet, homoerotic courting imagery and question of the status of the women shown. The thesis also contains an appendix which lists twenty-nine vases with copulation scenes. In addition, there are forty-five illustrations. The main contribution made by this thesis is the discovery of the close link between Dionysian imagery and the depiction of human copulation in Attic black-figure. This throws into question the distinction made by previous scholarship between erotica which is designed to titilate and religious expressions of fertility rites. Also of interest is the frequency of multiple copulation scenes and the relative paucity of single-couple heterosexual copulations.

description: Pakistan is experiencing an undersupply of electricity, causing load shedding several hours per day due to the adherence to conventional energy resources having quantitative and environmental limitations. Fossil fuels generate more than half of the country's total electricity, but they will ultimately run out due to their limited supply. Their combustion emits greenhouse gases, posing environmental threats. Since the world is tending toward efficient and sustainable alternative methods for harvesting energy from nature, Pakistan has also been investigating an elevated deployment of renewable energy projects. This paper presents a critical analysis of the present energy sector of Pakistan along with global scenarios. Pakistan relies on mainly thermal, hydro, and nuclear energy for power generation. National solar, wind, geothermal, and biomass resources have not been extensively explored and implemented. This paper provides an insight into the potential of these resources in Pakistan to generate electricity for the national grid on a large scale. It focuses on biomass energy, which can be harnessed from bagasse, poultry waste, and municipal waste for power production, and biomass-based fuel for industries and transportation. It concludes that biomass is the most sustainable, available, implementable, and environment-friendly resource that can be utilized to lessen the energy demand and supply gap in Pakistan.

description: We report the discovery of PSR J1757-1854, a 21.5-ms pulsar in a highly-eccentric, 4.4-h orbit with a neutron star (NS) companion. PSR J1757-1854 exhibits some of the most extreme relativistic parameters of any known pulsar, including the strongest relativistic effects due to gravitational-wave damping, with a merger time of 76 Myr. Following a 1.6-yr timing campaign, we have measured five post-Keplerian parameters, yielding the two component masses (m(p) = 1.3384(9) M-circle dot and m(c) = 1.3946(9) M-circle dot) plus three tests of general relativity, which the theory passes. The larger mass of the NS companion provides important clues regarding the binary formation of PSR J1757-1854. With simulations suggesting 3-sigma measurements of both the contribution of Lense-Thirring precession to the rate of change of the semimajor axis and the relativistic deformation of the orbit within similar to 7-9 yr, PSR J1757-1854 stands out as a unique laboratory for new tests of gravitational theories.

description: 4-methylbenzylidene camphor (4-MBC) is used as a UV-B filter in cosmetics. Two oxidized metabolites of 4-MBC - 3-(4-carboxybenzylidene)camphor (cx-MBC) and 3-(4-carboxybenzylidene)-6-hydroxycamphor (cx-MBC-OH) - were analyzed in 250 24-h urine samples from young adults in Germany. The samples were from the German Environmental Specimen Bank (ESB) and represented exposure in the years 1995, 2005, 2010, 2015 and 2019. A UHPLC-MS/MS method enabled the sensitive determination of both metabolites, with limits of quantifi cation at 0.15 mikrogL-1 (cx-MBC) and 0.30 mikrogL-1 (cx-MBC-OH), respectively. A temporal trend of the internal exposure to 4-MBC was clearly noticeable. The metabolite cx-MBC was frequently quantifiable at the beginning of the period: in 70% of the samples in 1995, and 56% in 2005. After 2005, urinary concentrations and detection rates of cx-MBC dropped to reach very low levels. In 2015 and 2019, the detection rate was only 2% and 0%, respectively. A similar trend was observed for cx-MBC-OH, though overall, this metabolite was detected less often and at lower concentration levels than cx-MBC. Nowadays, measurable levels of urinary 4-MBC metabolites are an extremely rare occurrence in Germany. These trends are consistent with the history of 4-MBC use by the cosmetic industry. The highest measured individual concentration of 16.20 mikrogL-1 (in a sample of the year 2005) was still more than 30 times below the health-based guidance value (HBM-I). An investigation of the ratios between both metabolites uncovered several features of the 4-MBC metabolism which have been essentially overlooked until now. In particular, stereochemical aspects should be explored in future studies. As urine was collected in autumn/winter in Northwestern Germany, the 4-MBC metabolites measured prob ably do not arise from sunscreen products in a narrow sense. They rather may reveal the use of other skin care products containing 4-MBC for UV protection as an added feature. © 2023 Elsevier

description: T cell activation and the generation of effective immune responses is critically dependent on APC-derived signalling. The relative expression of B7 isoforms on APC may be important in determining the nature and extent of the immune response, and immunoregulatory cytokines may mediate their effects through alterations in B7 isoform expression. The effects of a panel of cytokines on B7 isoform expression on resting and activated monocytes and B cells was evaluated. IL10 and IL4, which induce the development of Th2 type T cells, downregulated expression of B7-2 and modestly upregulated expression of B7-1 on unstimulated human monocytes. IFN$\gamma,$ a potent inducer of Th1 type T cells, upregulated both B7-1 and B7-2 expression. TNF$\alpha$ downregulated B7-2 expression, but did not alter B7-1 expression. Addition of anti-IL10 antibodies did not abrogate the effects of TNF$\alpha$ on B7-2 expression. LPS had effects on B7 isoform expression on purified monocytes similar to those of IL10 in PBMC, namely marked B7-2 downregulation and modest B7-1 upregulation. None of the cytokines influenced the levels of expression of B7 isoforms on either resting or activated B cells. Thus cytokines that influence development of T helper type immune responses have differential effects on expression of individual B7 isoform on monocytes but not on B cells. These findings may have important implications in activation and control of immune responses in infections, autoimmunity and malignancies.

description: In December 2019, a COVID-19 epidemic was discovered in Wuhan, China, and since has disseminated around the world impacting human health for millions. Herein, in-silico drug discovery approaches have been utilized to identify potential natural products (NPs) as Severe Acute Respiratory Syndrome coronavirus 2 (SARS-CoV-2) main protease (Mpro) inhibitors. The MolPort database that contains over 100,000 NPs was screened and filtered using molecular docking techniques. Based on calculated docking scores, the top 5,000 NPs/natural-like products (NLPs) were selected and subjected to molecular dynamics (MD) simulations followed by molecular mechanics–generalized Born surface area (MM-GBSA) binding energy calculations. Combined 50 ns MD simulations and MM-GBSA calculations revealed nine potent NLPs with binding affinities (ΔGbinding ) > −48.0 kcal/mol. Interestingly, among the identified NLPs, four bis([1,3]dioxolo)pyran-5-carboxamide derivatives showed ΔGbinding  > −56.0 kcal/mol, forming essential short hydrogen bonds with HIS163 and GLY143 amino acids via dioxolane oxygen atoms. Structural and energetic analyses over 50 ns MD simulation demonstrated NLP-Mpro complex stability. Drug-likeness predictions revealed the prospects of the identified NLPs as potential drug candidates. The findings are expected to provide a novel contribution to the field of COVID-19 drug discovery. Communicated by Ramaswamy H. Sarma
The development and exploration of the influence of a decision aid for sequential paediatric bilateral cochlear implantation

Subjects: subject: Health Sciences, Medicine and Surgery.
subject: Health Sciences, Public Health.

description: Introduction. Bilateral paediatric cochlear implantation is a new clinical option for children with bilateral severe to profound hearing loss. The benefits and risks associated with the procedure need to be understood by parents and considered in light of their personal values before making an acceptable decision. Objectives. (1) To explore the decision-making needs of parents regarding cochlear implants (CIs). (2) To provide updated, comprehensive information on the risks and benefits associated with paediatric bilateral CIs. (3) To develop and pilot a decision aid for sequential paediatric bilateral CIs. Methods. (1) Clinicians and parents were interviewed using a semi-structured approach, regarding CI decisions that are perceived to be difficult, barriers and facilitators to decision-making, and potential strategies for overcoming barriers. (2) Published research on paediatric CI benefits and risks was systematically gathered and synthesized. A retrospective chart review of local CI surgeries was also undertaken to estimate risks. (3) A decision aid was designed based on parents needs, reviews of benefits and risks, and international (IPDAS) standards. (4) A pre-test post-test design was used to pilot the decision aid and measure knowledge and decisional conflict aid with parents. The acceptability of the decision aid was assessed by parents and clinicians post-decision aid. Results. The need for additional decisional support was identified for some parents, particularly for bilateral CI decisions. The benefits and risks of bilateral implantation were systematically identified, documented, and estimated. A decision tool was designed to provide information about the options, their risks and benefits, as well as tools for parents to clarify and communicate the value they attribute to the risks and benefits. The piloted decision aid was acceptable to parents and clinicians and significant improvements in parents' knowledge were noted. Conclusion. Parents considering the bilateral CI decision have needs that are not being met with current decision support. An intervention that addresses this clinical gap was designed with updated evidence of benefits and risks and shows promise in improving parental decision-making for their children with hearing loss.

description: Soil total nitrogen (STN) is an important indicator of soil quality and plays a key role in global nitrogen cycling. Accurate prediction of STN content is essential for the sustainable use of soil resources. Synthetic aperture radar (SAR) provides a promising source of data for soil monitoring because of its all-weather, all-day monitoring, but it has rarely been used for STN mapping. In this study, we explored the potential of multi-temporal Sentinel-1 data to predict STN by evaluating and comparing the performance of boosted regression trees (BRTs), random forest (RF), and support vector machine (SVM) models in STN mapping in the middle reaches of the Heihe River Basin in northwestern China. Fifteen predictor variables were used to construct models, including land use/land cover, multi-source remote sensing-derived variables, and topographic and climatic variables. We evaluated the prediction accuracy of the models based on a cross-validation procedure. Results showed that tree-based models (RF and BRT) outperformed SVM. Compared to the model that only used optical data, the addition of multi-temporal Sentinel-1A data using the BRT method improved the root mean square error (RMSE) and the mean absolute error (MAE) by 17.2% and 17.4%, respectively. Furthermore, the combination of all predictor variables using the BRT model had the best predictive performance, explaining 57% of the variation in STN, with the highest R2 (0.57) value and the lowest RMSE (0.24) and MAE (0.18) values. Remote sensing variables were the most important environmental variables for STN mapping, with 59% and 50% relative importance in the RF and BRT models, respectively. Our results show the potential of using multi-temporal Sentinel-1 data to predict STN, broadening the data source for future digital soil mapping. In addition, we propose that the SVM, RF, and BRT models should be calibrated and evaluated to obtain the best results for STN content mapping in similar landscapes.

description: We use the energy-balance code MAGPHYS to determine stellar and dust masses, and dust corrected star-formation rates for over 200,000 GAMA galaxies, 170,000 G10-COSMOS galaxies and 200,000 3D-HST galaxies. Our values agree well with previously reported measurements and constitute a representative and homogeneous dataset spanning a broad range in stellar mass (10^8---10^12 Msol), dust mass (10^6---10^9 Msol), and star-formation rates (0.01---100 Msol per yr), and over a broad redshift range (0.0 < z < 5.0). We combine these data to measure the cosmic star-formation history (CSFH), the stellar-mass density (SMD), and the dust-mass density (DMD) over a 12 Gyr timeline. The data mostly agree with previous estimates, where they exist, and provide a quasi-homogeneous dataset using consistent mass and star-formation estimators with consistent underlying assumptions over the full time range. As a consequence our formal errors are significantly reduced when compared to the historic literature. Integrating our cosmic star-formation history we precisely reproduce the stellar-mass density with an ISM replenishment factor of 0.50 +/- 0.07, consistent with our choice of Chabrier IMF plus some modest amount of stripped stellar mass. Exploring the cosmic dust density evolution, we find a gradual increase in dust density with lookback time. We build a simple phenomenological model from the CSFH to account for the dust mass evolution, and infer two key conclusions: (1) For every unit of stellar mass which is formed 0.0065---0.004 units of dust mass is also formed; (2) Over the history of the Universe approximately 90 to 95 per cent of all dust formed has been destroyed and/or ejected.

description: The understanding of the role of sphingolipid metabolism in cancer has tremendously increased in the past ten years. Many tumors are characterized by imbalances in sphingolipid metabolism. In many cases, disorders of sphingolipid metabolism are also likely to cause or at least promote cancer. In this review, sphingolipid transport proteins and the processes catalyzed by them are regarded as essential components of sphingolipid metabolism. There is much to suggest that these processes are often rate-limiting steps for metabolism of individual sphingolipid species and thus represent potential target structures for pharmaceutical anticancer research. Here, we summarize empirical and biochemical data on different proteins with key roles in sphingolipid transport and their potential role in cancer.

description: Synthesis of polymer nanocomposites with novel shear stiff, mica-like nanoplatelets from a synthetic layered silicate is presented. This novel synthetic clay filler shows high aspect ratios while organophilization may be selectively restricted to external surfaces minimizing the organic content of the filler. The obtained nanocomposite shows superior mechanical, thermal and fire properties as compared to commonly used natural clays. Furthermore, the influence of the blending method on the nanocomposite properties was investigated.
Using interior point methods to solve the multicommodity network flow problem.

Subjects: subject: Engineering, System Science.

description: This thesis explores applications of Interior Point methods as popularized by Karmarkar (36) for solving Multicommodity Network Flow problems (MCNF). In these problems, several commodities must be shipped between various nodes of a network. The goal is to satisfy the shipping requirements at a minimum cost, while respecting processing capacities on the joint flow of commodities. The thesis presents a unified view of current methods for multicommodity networks, from the early formulations to current work that has involved nonlinear and interior point methods. It compares and contrasts some Interior Point methods, and discusses how they can be applied to the MCNF problem. It builds upon the first Interior Point partitioning method proposed to solve MCNF, and implements a related partitioning method. This scheme allows network subproblems to be solved using efficient network simplex algorithms: then the results are coordinated using a linear program that is solved with an Interior Point affine scaling algorithm. It presents computational results, comparing the results from the partitioning method with those found by solving an LP formulation of the problem using the affine scaling method.
De la soumission à l'émancipation?: La quête d'agentivité des héroïnes de "La dame dans l'auto avec des lunettes et un fusil" et de "Piège pour Cendrillon" de Sébastien Japrisot

description: Le mouvement féministe des années quatre-vingt a fourni de nouvelles approches analytiques aux littéraires: études des rôles sexuels, des relations hommes/femmes, etc. La littérature policière s'est alors vue, elle aussi, investie par des auteures femmes et des protagonistes féminins qui ont fait entrer la femme dans une littérature qui l'avait jusqu'alors sous-représentée. Pourtant, de telles avancées ne se produisent pas subitement et nous pouvons en déduire que des oeuvres précurseurs existent, oeuvres dans lesquelles l'auteur alloue au personnage féminin un espace narratif dans lequel il peut évoluer et grandir. Sébastien Japrisot, nous le croyons, fait partie de ces auteurs. Les héroïnes de La dame dans l'auto avec des lunettes et un fusil et de Piège pour Cendrillon sont certes des victimes, mais à qui l'auteur a donné certains outils pour s'affirmer et dénoncer. En nous appuyant sur les études féministes en policier ainsi que sur les théories de l'agentivité, nous souhaitons montrer la quête d'agentivité des protagonistes, c'est-à-dire comment ces femmes parviennent à passer d'un état passif à un état agent, et ce malgré leur rôle de victime. Par conséquent, nous pourrons montrer de quelle façon ces deux romans de Japrisot ont participé à ouvrir certaines possibilités dans la représentation d'un nouveau féminin dans la littérature policière.

Water and electrolyte balance in normal and hypertrophied hearts.

description: The condition of arteriosclerosis was simulated in male, Wistarstrain rats by sub-diaphragmal aortic constriction. Two days after constriction, a significant (P < 0.05) increase in cardiac mass had occurred. Significant changes in extracellular fluid volume and electrolyte content of the left ventricle, right ventricle and atrium were found much sooner than changes in cardiac mass and may thus play a role as instigating factors in the mechanism of cardiac hypertrophy. The extracellular fluid volume was measured by a radioactive isotope dilution method employing S35-sulphate. Significant increases in sulphate space and sodium content were found to occur in the left ventricle within 24 hours after aortic constriction. These increases became even more significant (P < 0.001) at 10 days, then both parameters decreased to within normal range between 2 and 3 weeks after aortic constriction. Close correlation (r = 0.915) was found between sulphate space and sodium content in both ventricles of hypertrophied hearts. Total water remained remarkably constant in the left ventricle but rose significantly in the right ventricle of hearts with the greatest degree of hypertrophy (over 66% increase). Potassium content remained unchanged in the left ventricle but dropped significantly in the right ventricle, as did total phosphate. The same parameters were measured in different regions of normal hearts of unoperated, 150 to 450 gram rats. It was found that sulphate space, total water, sodium content, intracellular potassium, etc. all reached maximal values in the 250 to 300 gram rats and then all (except sodium) decreased in larger rats. Because this weight group occurs at the steepest part of the normal growth curve, these changes in water and electrolyte values are thus associated with rapid normal growth as well as with the accelerated growth of cardiac hypertrophy. Possible reasons for the observed changes in water and electrolyte balance are discussed from the point of view of hormonal, metabolic, hemodynamic and physical changes.

description: The natural plant toxin asimicin and the standardized extract F020 from Asimina triloba (Annonaceae) were examined for their insecticidal properties using six insect species, encompassing four orders. Growth of Ostrinia nubilalis and Manduca sexta larvae was inhibited at 100 and 500 $\mu$g F020$\cdot$g diet$\sp{-1}$, respectively and mortality was significantly higher than controls at levels as low as 500 and 1 $\mu$g F020$\cdot$g diet$\sp{-1}$, respectively. Antifeedant properties were observed. Toxicity and growth reduction from exposure to F020 were apparent for Oncopeltus fasciatus (Hemiptera) and Tenebrio molitor (Coleoptera). Tenebrio molitor was significantly affected at doses as high as 250 $\mu$g F020$\cdot\mu$l$\sp{-1}$ and at 20 $\mu$g asimicin$\cdot\mu$l$\sp{-1}$. Examination of the effect of F020 on the respiratory rate of third instar O. nubilalis larvae demonstrated that F020 is an effective respiratory inhibitor. Both F020 and asimicin were very effective at inhibiting complex I, the NADH-ubiquinone site of the electron transport chain. The EC$\sb{50}$ values for inhibition of state 3 respiration by asimicin and F020 were 0.546 nmoles$\cdot$mg protein$\sp{-1}$ and 1.656 $\mu$g$\cdot$mg protein$\sp{-1}$, respectively.

description: Background: To review women with symptomatic and clinically progressive endometriosis after menopause in the absence of estrogen intake or excessive systemic endogenous production. Design: Seven case reports and a systematic review of the literature from 1995 till February 2018. Results: Only 7 case reports from the authors and 29 cases from the literature described women with either cystic ovarian or deep endometriosis. Severity, symptoms, and localization are highly variable. No case report describes symptomatic superficial typical lesions. In 22 of 36 women (61%), symptoms started more than 10 years after menopause. Conclusions: Symptomatic and clinically progressive endometriosis after menopause in the absence of increased systemic estrogen concentrations or exogenous estrogen intake starts more than 10 years after menopause in the majority of women. This observation suggests that a genetic and/or epigenetic incident caused estrogen-independent progression, increased sensitivity to estrogens or increased local production of estrogens. This observation is important for understanding the pathophysiology of endometriosis, for the management of postmenopausal endometriosis, and for individualization of medical therapy of endometriosis since estrogen-independent endometriosis growth probably also occurs before menopause.

description: Double neutron stars (DNSs) have been observed as Galactic radio pulsars, and the recent discovery of gravitational waves from the DNS merger GW170817 adds to the known DNS population. We perform rapid population synthesis of massive binary stars and discuss model predictions, including DNS formation rates, mass distributions, and delay time distributions. We vary assumptions and parameters of physical processes such as mass transfer stability criteria, supernova natal kick distributions, remnant mass prescriptions, and common-envelope energetics.We compute the likelihood of observing the orbital period-eccentricity distribution of the Galactic DNS population under each of our population synthesis models, allowing us to quantitatively compare the models.We find that mass transfer from a stripped post-heliumburning secondary (case BB) on to a neutron star is most likely dynamically stable. We also find that a natal kick distribution composed of both low (Maxwellian σ = 30 km s-1) and high (σ = 265 km s-1) components is preferred over a single high-kick component. We conclude that the observed DNS mass distribution can place strong constraints on model assumptions.
