description: The aging of a charged colloidal system has been studied by Small Angle X-rays Scattering, in the exchanged momentum range Q=0.03 - 5 nm-1, and by Dynamic Light Scattering, at different clay concentrations (Cw =0.6 % - 2.8 %). The static structure factor, S(Q), has been determined as a function of both aging time and concentration. This is the first direct experimental evidence of the existence and evolution with aging time of two different arrested states in a single system simply obtained only by changing its volume fraction: an inhomogeneous state is reached at low concentrations, while a homogenous one is found at high concentrations.

description: Automatic phenotype concept recognition from unstructured text remains a challenging task in biomedical text mining research. Previous works that address the task typically use dictionary-based matching methods, which can achieve high precision but suffer from lower recall. Recently, machine learning-based methods have been proposed to identify biomedical concepts, which can recognize more unseen concept synonyms by automatic feature learning. However, most methods require large corpora of manually annotated data for model training, which is difficult to obtain due to the high cost of human annotation. In this paper, we propose PhenoTagger, a hybrid method that combines both dictionary and machine learning-based methods to recognize Human Phenotype Ontology (HPO) concepts in unstructured biomedical text. We first use all concepts and synonyms in HPO to construct a dictionary, which is then used to automatically build a distantly supervised training dataset for machine learning. Next, a cutting-edge deep learning model is trained to classify each candidate phrase (n-gram from input sentence) into a corresponding concept label. Finally, the dictionary and machine learning-based prediction results are combined for improved performance. Our method is validated with two HPO corpora, and the results show that PhenoTagger compares favorably to previous methods. In addition, to demonstrate the generalizability of our method, we retrained PhenoTagger using the disease ontology MEDIC for disease concept recognition to investigate the effect of training on different ontologies. Experimental results on the NCBI disease corpus show that PhenoTagger without requiring manually annotated training data achieves competitive performance as compared with state-of-the-art supervised methods.

description: The paper aims at reflecting on relation and communication in education. The first part proposes a brief pedagogical theoretical framework on the topic of communication within the educational relationship, and it underlines the concept of empathy. A discussion on the role of the educator follows to focus on the helping relationship to explore the topic of the management of communicative and relational dynamics. By arguing on the etymology and the misuse of the word “dynamic”, a reflection is proposed on the concept of strength and of communication as the meeting between two strengths. The third part discusses about the communication skills and, according to what shown before, proposes and reflects on counselling microskills that have been taught on University lectures for educators. Conclusions underline possible developments and attentions to be integrated in designing university training on communicational and relational skills for educators.

description: Peers may help others avoid violating organisational information security policies (ISPs). This study explores how peer monitoring reduces employee ISP violation intention. We propose that peer monitoring discourages employees from violating ISP. Moreover, trust plays an important role. Trust not only facilitates peer monitoring, but also moderates the effect of peer monitoring on employee ISP violation intention. In addition, collective responsibility leads to peer monitoring. We test our research model with data from two waves of surveys of 254 employees in the United States conducted two weeks apart. We utilise four scenarios in the second wave of surveys capturing the dependent variable and measure all other constructs in the first wave of surveys. Our results suggest that peer monitoring decreases one’s intention to violate ISPs. Furthermore, both collective responsibility and trust contribute to peer monitoring. Finally, trust amplifies the effect of peer monitoring on employees’ intention to violate ISPs. We discuss the theoretical contributions and practical implications.

description: This poster paper analyses the international marketing and trade strategies implemented by italian quality food producers with special attention to the export and trade aspects for some important Italian PDOs products: Prosciutto di Parma PDO and Parmigiano Reggiano PDO. Discussing the international marketing and trade strategies, according to the traditional 4P approach, the poster paper will report examples of the strategies of the exporters and would focus on the rapid change in trading and distribution channel. The future of PDO products is not only connected to their positioning, to their promotion and international protection but also to the strategies of the retail leaders and to the overall strategy of the procucers, that range from small companies to international companies. The latter is more and more present in these markets of "typical products" which represent a diversification and a good investment to improve market positioning.
Exceptional points of degeneracy in traveling wave tubes

Subjects: subject: Classical Physics (physics.class-ph)
subject: FOS: Physical sciences

description: Traveling wave tube (TWT) is a powerful vacuum electronic device used to amplify radio-frequency (RF) signals with numerous applications, including radar, television and telephone satellite communications. TWT design in a nutshell comprises of a pencil-like electron beam (e-beam) in vacuum interacting with guiding it slow-wave structure (SWS). In our studies here the e-beam is represented by one-dimensional electron flow and SWS is represented by a transmission line (TL). The interaction between the e-beam and the TL is modeled by an analytic theory that generalizes the well-known Pierce model by taking into account the so-called space-charge effects particularly electron-to-electron repulsion (debunching). Many important aspects of the analytic theory of TWTs have been already analyzed in our monograph on the subject. The focus of the studies here is on degeneracies of the TWT dispersion relations particularly on exceptional points of degeneracy and their applications. The term exceptional point of degeneracy (EPD) refers to the property of the relevant matrix to have nontrivial Jordan block structure. Using special parameterization particularly suited to chosen EPD we derive exact formulas for the relevant Jordan basis including the eigenvectors and the so-called root vector associated with the Jordan block. Based on these studies we develop constructive approach to sensing of small signals.
The intention of tradition : contemporary contexts and contests of the Kwakwaka’wakw Hamat’sa dance
Creators: name: Glass, Aaron J.
Publisher: name: University of British Columbia
Year: 2009

description: This thesis explores the dialectical relationship between aboriginal and anthropological discourses of tradition and cultural performance. Specifically, I examine some ways in which concepts of tradition and culture are invoked in British Columbia's First Nations communities in order to negotiate, validate, and contest contemporary transformations to cultural practice. Two case studies of recent controversies within Kwakwaka'wakw communities are presented, one surrounding the bestowal of the Hamat'sa Dance on the pan-tribal American Indian Dance Theater for use in public presentations, the other involving the performance of the Hamat'sa— customarily a male prerogative— by women. This study addresses both local Kwakwaka'wakw dialogues about history and contemporary values, and the larger public, academic, and political environments in which those dialogues occur. This thesis takes as its broadest context these dialogues and shifts in the scale of identity and representation: between different native communities and different voices within them; between contests for local privilege and global control over "national" heritage; between indigenous peoples and the discipline of anthropology. I argue that tradition is best approached as a critical value emerging from these discourses, a concept which is intentionally used as a marker of present identity through strategic appeal to the past.

To explain this effect we develop a theory taking into account the nonlinearity of the fluid. The theory is validated through an experiment to measure the dynamic radiation force on an acrylic sphere. Results exhibit an amplification of 66 dB in water and 80 dB in alcohol as the difference of the frequencies is increased from 10 Hz to 240 kHz.

description: The recognition of the knowledge and skills about relational and communicational area as central elements in the architecture of the Educational Sciences Courses is a key step in the more general acknowledge of the profession of educator. However, the translation of those in terms of epistemological, theoretical and methodological approaches can follow other logics than the educational ones, especially when higher education is constantly imbued with neo-liberal thinking. For this reason, based of the experience conducted at the University “Suor Orsola Benincasa” in Naples, the paper proposes to re-read, considering the Deweyan transactional approach: 1) the relationship and communication as a natural substratum within which educational practice intervenes; 2) educational practice, as intentional and reflective. It follows that such knowledge and skills can be developed thanks to inquiry-based activities, i.e. observation, questioning, problematization, and documentation.

description: Several pedagogical Authors already stressed that, working with vulnerable families, neither educative relationship, nor communicative act, which compose or nourish it, can exclude educators’ emphatic and introspective skills. According to this perspective, the paper therefore seeks to define a didactic Syllabus aimed at orienting teachers and tutors in implementing empathic and introspective abilities of their learners, which is based on the experiential and reflective learning approach. This propose, outlined by goals, didactic, and assessment strategies, would be a starting point for promoting wider discussions on didactic practices characterizing the learning paths of educators, students, or professionals.

description: This paper reports a study of the horticultural chain in Fiji. The objectives of the research was to understand how the domestic horticultural supply could meet the demand currently generated by the tourism sector, i.e. how new income opportunities for the rural people could be generated by feeding the tourists. If policy interventions are to be directed at strengthening backward economic linkages between tourism and local food supplier, a better understanding of factors driving farmers marketing choice is required. This paper aims to contribute in this regard by analyzing the decisions of farmers to engage in direct selling to hotels. Hotels pay premium prices for quality fresh produce and direct marketing can allow farmers to retain the highest possible portion of this premium without sharing it with intermediaries. The results of the application of a discrete choice model to data collected in the chain study, suggest that quality is the most important factor among those affecting the choice of direct marketing to hotels. Other variables influencing the decision were found to be ethnicity, distance from the market and the availability of transportation means of property.

description: This paper depicts how the general turn from mass consumption toward increased qualitative differentiation of products - the 'quality turn' - manifest in the South African agro-food system. The strong influence of these quality trends on agro-food systems evolution has been widely discussed in Europe and North America. We show that identifying quality related dynamics is bringing an interesting perspective into understanding some of the evolution of the local agro-food system. The discussion is mainly based on the perspective of the organic sector. Most domestic retailers' food quality positioning is in line with consumer trends, being general and price orientated. However, the retail sector has been entering and driving quality related niche markets, especially organics, fostering new organizational arrangements through certification schemes development. Price premiums and consumer behavior analysis associated with organic production reveal significant consumers' willingness to pay for immaterial product attributes (e.g. health) and reflect the current supply and demand imbalance in the organic sector. The leading role of the retail sector in conveying quality movements is instrumental in understanding the discussed evolution. Pointing out the growing interest in farmer's markets provides elements to foresee new development in the agro-food system and departure from the retail driven quality movement.
Galaxy rotation curve in hyperconical universes: a natural relativistic MOND

description: Modified Newtonian dynamics (MOND) and similar proposals can (at least partially) explain the excess rotation of galaxies or the equivalent mass-discrepancy acceleration, without (or by reducing) the requirement of dark matter halos. This paper develops a modified gravity model to obtain a local limit to general relativity (GR) compatible with a cosmological metric different from the standard Friedmann--Lema\^ıtre--Robertson--Walker metric. Specifically, the paper uses a distorted stereographic projection of hyperconical universes, which are 4D hypersurfaces embedded into 5D Minkowski spacetime. This embedding is a key in the MOND effects found in galactic scales. To adequately describe the mass-discrepancy acceleration relation, the centrifugal force would present a small time-like contribution at large-scale dynamics due to the curvature of the Universe. Therefore, the Lagrangian density is very similar to GR but with subtracting the background curvature (or vacuum energy density) of the perturbed hyperconical metric. Results showed that the proposed model adjusts well to 123 galaxy rotation curves obtained from the Spitzer Photometry and Accurate Rotation Curves database, using only a free parameter.

description: An increasing interest in geographical indications of origin (GIs) as a tool of product differentiation can be observed in the so-called specialty coffee sector. Similar to the approach for wine in France and Italy, more and more coffee-producing countries try to establish appellations systems for coffee. Whereas some countries and regions such as Colombia or Jamaica have already legally protected GIs for coffee, most coffee GIs are still informal meaning that no legal protection has been obtained so far. But the recent acceptation of the term Café de Colombia as a Protected Geographical Indication (PGI) in the EU and the Ethiopian Trademark Initiative document the increasing engagement of coffee-producing countries to achieve an appropriate legal protection for their GIs. From an economic point of view, data from US online retail stores indicate that single-origin coffees receive significant higher retail prices, with 100% Kona coffee from Hawaii and Jamaican Blue Mountain coffee being the most expensive ones. Furthermore, results from a hedonic pricing model based on internet auction data for single-origin coffees show that the country and the region of origin is already an important determinant of prices paid by importers and roasters.

description: Consumers' use of quality characteristics to make milk purchase decisions reveal opportunities to create successful marketing strategies. Such a strategy could concern food quality. In this case, three core areas influence consumers' quality perception: the perception process, the physical product itself and the communication about it (Grunert et al., 1996). Beyond this background, this article analyzes the impact of certain quality characteristics and socio-demographics on consumption patterns regarding whole fat milk, skim milk and organic milk. These milks were chosen because of the increasing awareness of different fat contents in the meaning of lower fat contents being healthier and the increasing importance of the organic food market. Steenkamp's (1990) concept of 'perceived quality' provides as theoretical background. To gather the data a consumer survey with 260 households took place in Germany in 2004. An ordered logit model and a cluster analysis were used for analyzing the data. We find clear differences in consumers' perception of quality characteristics for the different milks. This information can be used to develop demand-oriented marketing activities (Kotler and Armstrong, 1994: 48).

description: Compton Gamma Ray Observatory, OSSE, SMM, TGRS, balloon and recent INTEGRAL data reveal a feature of the 0.511 MeV annihilation radiation of the Galactic Center with a flux of approximately 5x 10^{-4}~0.511 MeV photons cm^{-2} s^{-1}. We argue that e+e- pairs can be generated when the X-ray radiation photons and ~10-30 MeV photons interact with each other in the compact region in the proximity of the Galactic Center black hole. In fact, disks formed near black holes of 10^{17} g mass should emit the ~ 10 MeV temperature blackbody radiation. If positron e+ sources are producing about 10^{42} e+ s^{-1} near the Galactic Center they would annihilate on the way out and result in 0.511 MeV emission. We suggest that the annihilation radiation can be an observational consequence of the interaction of the accretion disk radiation of the SMall Mass Black Holes (SMMBHs) with X-ray radiation in the Galactic Center. This is probably the only way to identify and observe these SMMBHs.

description: The implementation of eco-labelling schemes for agricultural and food products may represent an opportunity to enhance production technologies compatible with the sustainable economic approach. The paper presents an attempt to design a comprehensive methodological framework in which the consumer behaviour change is the driving force for redirecting the market, the production, and the international trade. This approach focuses on the specification of the most relevant variables necessary to implement a simplified, but comprehensive analysis, from which it is possible to proceeding to a broad estimate of the changes in terms of consumption patterns, revenue distribution, import and export, and natural resources consumption. On a theoretical basis, the framework highlights that the most relevant conservation effect on natural resources, occurs when the eco-labelling schemes are enforced by two countries, under a market regime of free trade. On the contrary, if only one country adopts the schemes, then the effect is negligible.

description: Genetic relationships between blood eosinophil count (BEC), asthma susceptibility, and severity are unclear. We sought to identify the genetic difference between type 2 (T2) and nontype 2 (non-T2) asthma (defined by BEC) and investigate genetic relationships between high BEC, asthma susceptibility, and severity. Genome-wide association studies (GWASs) were performed for T2 (n = 9,064; BEC ≥ 300 cells/μL) versus non-T2 asthma (n = 14,379; BEC < 150 cells/μL) and asthma susceptibility (37,227 asthmatics vs. 124,132 nonasthma controls) in the UK Biobank and asthma severity (moderate-to-severe asthma [n = 2,153] vs. mild asthma [n = 5165]) in the All of Us Research Program (AoURP). Genetic causality between BEC, asthma susceptibility, and severity were dissected using Mendelian randomization (MR). High BEC was associated with asthma and decreased pulmonary function. GWASs revealed four sets of genetic variants (p < 5 × 10−8): genes associated with only BEC or asthma and genes associated with high BEC and asthma in the same or opposite direction. The C allele of rs653178 in ATXN2 was associated with high BEC, risk for autoimmune diseases, and protection for asthma. Genetic variants associated with BEC or asthma were not associated with asthma severity. MR indicated high BEC and asthma were in bidirectional causal relationship (p < .001); however, they were not causal for asthma severity. Genetic variants associated with asthma or BEC and asthma severity are distinctive. High BEC is a risk factor for asthma; however, it is neither necessary nor sufficient for asthma susceptibility and severity.

description: The global dynamics of the two-species Lotka-Volterra competition patch model with asymmetric dispersal is classified under the assumptions of weak competition and the weighted digraph of the connection matrix is strongly connected and cycle-balanced. It is shown that in the long time, either the competition exclusion holds that one species becomes extinct, or the two species reach a coexistence equilibrium, and the outcome of the competition is determined by the strength of the inter-specific competition and the dispersal rates. Our main techniques in the proofs follow the theory of monotone dynamical system and a graph-theoretic approach based on the Tree-Cycle identity.

description: Training of socio-pedagogical educators is being continuously renewed and open to dialogue with personal and relational spaces they live in. From family to educational settings, students take care of their own professional expectations, thanks to the activation of democratic and participatory dynamics, which make them work in teams and address community complex contexts. In order to comprehend and underline the transformative value of Pedagogy, the paper shows a training experience, run with students of the Degree Course in Education Science, in which communication and relational dynamics within small group are highlighted. The analysis, which focuses on the impact of the didactical strategies selected for the development of the above mentioned experience, is run through pedagogical reflections on the emerged meanings and by valorising students’ expertise and perceptions, with a design-perspective, starting from the collection of their own feedback.

description: In this article, we clarify the link between the conformal (i.e. Weyl) correspondence from the Minkowski space to the de Sitter space and the conformal (i.e. SO(2,$d$)) invariance of the conformal scalar field on both spaces. We exhibit the realization on de Sitter space of the massless scalar representation of SO$(2,d)$. It is obtained from the corresponding representation in Minkowski space through an intertwining operator inherited from the Weyl relation between the two spaces. The de Sitter representation is written in a form which allows one to take the point of view of a Minkowskian observer who sees the effect of curvature through additional terms.

First a short review of the literature on channel structure and product differentiation is presented, in order to identify, on a theoretical grounding the incentives for differentiation strategies. Second, a case study is drawn of a UK channel intermediary organisation carrying out differentiation policies in the fresh produce category (on behalf of UK multiple retailer customers) supplied by a dedicated Italian grower. Results show that in the fresh produce industry there is room for product differentiation, but with contradictory welfare effects.
Including beyond-linear halo bias in halo models

Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)

description: We derive a simple prescription for including beyond-linear halo bias within the standard, analytical halo-model power spectrum calculation. This results in a corrective term that is added to the usual two-halo term. We measure this correction using data from $N$-body simulations and demonstrate that it can boost power in the two-halo term by a factor of $\sim2$ at scales $k\sim0.7\,h Mpc^{-1}$, with the exact magnitude of the boost determined by the specific pair of fields in the two-point function. How this translates to the full power spectrum depends on the relative strength of the one-halo term, which can mask the importance of this correction to a greater or lesser degree, again depending on the fields. Generally we find that our correction is more important for signals that arise from lower-mass haloes. When comparing our calculation to simulated data we find that the under-prediction of power in the transition region between the two- and one-halo terms, which typically plagues halo-model calculations, is almost completely eliminated when including the full non-linear halo bias. We show improved results for the auto and cross spectra of galaxies, haloes and matter. In the specific case of matter-matter or matter-halo power we note that a large fraction of the improvement comes from the non-linear biasing between low- and high-mass haloes. We envisage our model being useful in the analytical modelling of cross correlation signals. Our non-linear bias halo-model code is available at https://github.com/alexander-mead/BNL

description: European Union (EU) retailers are setting global benchmarks for the production of fresh food, and are asking their suppliers for produce to be certified according to food safety and quality standards. Compliance to these standards for developing countries small-scale producers entail costly investment in variable inputs and long term structures. Limited empirical evidence exists either to refute or confirm the concern that the proliferation and enhanced stringency of these standards marginalize smallholders from global market. This article therefore explores the costs of compliance, factors explaining the smallholder decision to adopt EU private quality standard and the impacts of the standard on farm financial performance. We develop a two-stage standard treatment effect model to account for self-selection as a source of endogeneity. Analysis is based on a random cross section sample of 439 small-scale export vegetable producers in Kenya whose production was monitored in 2005/2006. We demonstrate that adopters and non-adopters are distinguishable by their asset holding and household wealth, access to services, labor endowment and level of education. Once we control for endogeneity problem, we found that small-scale producers can benefit substantially from adopting the standard at the farm level.

description: In recent years an increasing consumer preference for regional food can be observed, both in Germany and in other European countries. Regression models investigating this region-of-origin effect are rare and in most cases the region or sample size under consideration is quite small. Different from that, the present study is based on a representative data set for Germany. Our objective is to identify and quantify the determining factors of consumers' preferences for regional food. Therefore, a theoretical construct is proposed and tested empirically by using a binary logit model. The results indicate that cognitive and normative factors are the main determinants on consumer preference for regional food, whereas affective and socio-demographic variables only are taking marginal influence. Especially consumers' perceptions, that regional food has better product attributes and offers a higher food safety, are significant and important determining factors. The same is true for the idea to support the domestic agriculture by purchasing locally grown food. Contrarily, no significant influence could be examined for most of the socio-demographic variables, e.g. level of education, location size, and level of income.

description: There is a theoretical vacuum within the study of mediation and mediators that develop the educator’s manage skills regards educational and training relations and situational dynamics. However, these are learning outcomes rooted in the theoretical constructs founding pedagogical theory and in the core contents of the L-19 Course. The contribution is therefore divided into two parts. In the first part, the Authors reconstruct the reasons for the shortage of empirical research of didactic matrix concerning the transposition of the knowledge of the relationship and educational communication. The second part discusses various aspects of the practice of teaching transposition within the university training of the socio-pedagogical educator refers to a chosen cultural object and in light of a collaborative research-training carried out in 2019-2020 at the Department of Education Science, Psychology, and Communication of the University Aldo Moro of Bari. The research, here shown in its methodological structure and outcomes, has been carried out with the second year students of L-19 Course, and it allowed to formalize some didactic mediation practices concerning Early Childhood 0-6 professional area. The paper intends to provide a contribution to the ongoing scientific debate on the construction of standards and profiles of competences referred the Law n. 205/2017.

description: Farm surveys are an indispensable tool for use at all levels of agricultural policy and in important phases in agricultural economics research. This paper is an attempt to synthesise some of the more important recent discussions that have centred round the roles of surveys in economics in general and in farming in particular. Farm surveys are comparatively recent in Australia. There is need for more of them, covering not only technical and financial data, but personal, subjective and institutional data also. Such surveys should be regarded as prerequisites for more effective policy-making in agriculture, and as such, provision for them should he incorporated within policy for its guidance and evaluation.
Power law tails of time correlations in a mesoscopic fluid model

description: In a quenched mesoscopic fluid, modelling transport processes at high densities, we perform computer simulations of the single particle energy autocorrelation function C_e(t), which is essentially a return probability. This is done to test the predictions for power law tails, obtained from mode coupling theory. We study both off and on-lattice systems in one- and two-dimensions. The predicted long time tail ~ t^{-d/2} is in excellent agreement with the results of computer simulations. We also account for finite size effects, such that smaller systems are fully covered by the present theory as well.

description: Emicizumab is a monoclonal antibody approved for prophylaxis against bleeds for people with hemophilia A (PwHA). A systematic review was conducted evaluating the efficacy/effectiveness and the safety of emicizumab as prophylaxis for PwHA compared to prophylaxis with factor VIII (FVIII) or bypassing agents (BPA), respectively in patients without and with inhibitors. Database-directed search strategies were performed in Aug/26/2022 and updated in Mar/16/2023. Studies evaluating the prophylaxis with emicizumab versus prophylaxis with FVIII or BPA in PwHA without or with inhibitors, respectively, were selected by two independent reviewers. Data were extracted by two independent reviewers. Annualized bleeding rates for total treated bleeding events (ABR-all) were evaluated by meta-analysis. The quality of studies and certainty of evidence were assessed. A total of 11 studies were included. The standard mean differences for ABR-all were −0.6 (95%CI −1.0 to −0.2, p-value = 0.0002), among PwHA without inhibitors, and −1.7 (95%CI −2.4 to −0.9, p-value <0.00001), among PwHA with inhibitors. However, there was moderate heterogeneity in both meta-analyses. The most frequent adverse event was injection site reaction. Emicizumab prophylaxis was superior in reducing the ABR-all when compared with prophylaxis with FVIII or BPA.

description: Objectives were to 1) assess COVID-19-associated medical and psychological challenges facing persons with inherited bleeding disorders (PIBD) and their parents/guardians (PG) in Germany, the US, and the UK; 2) describe similarities and differences among these countries; 3) identify needs and opportunities for intervention by patient advocacy organizations (PAGs).    A cross-sectional, international survey was conducted in three countries using validated psychometric instruments and investigator-developed items.   Five hundred and four surveys were included. Significant differences between countries were found including experiences with medical care, specific thoughts, and concerns about COVID-19, anxiety, and other mental health measures, as well as resources used to cope with stress. Age, education, income, race, IBD diagnosis, PIBD vs. BD group, and gender had moderating effects on resources used. Communication with friends/relatives and use of PAG and HTCs as resources for information/coping decreased in all countries during the pandemic.   There were similarities and differences between respondents across the country in the perceived impact of the pandemic, mental health scores, and strategies used to cope with stress.  Recommendations: strategies to increase PAG access for PIBD and their PG during pandemics and natural disasters, ongoing assessment and adaptation to provide supportive resources to specific patient subgroups. Persons with inherited bleeding disorders (PIBD) and their parents faced many challenges during the COVID-19 pandemic. An online survey was conducted within three countries: Germany, the United States, and the United Kingdom to explore these challenges and address how patient advocacy organizations can better meet their needs. Areas explored included experiences with medical care, concerns, and thoughts expressed during the pandemic, and coping resources used before and during the pandemic. In addition, mental health issues were explored addressing anxiety, COVID-related fears, depression, and resilience. Differences were found regarding experiences with medical care, specific thoughts, and concerns about COVID-19, anxiety, and other mental health measures, as well as resources used to cope with stress. These results provide an opportunity for advocacy organizations for PIBD to develop appropriate assessment, adaptation, and education resources to help patients during pandemics and/or natural disasters in the future.

description: We analyzed archival X-ray spectra of MXB 1728-34 obtained in 1996-99 by the Proportional Counter Array on board of the RXTE satellite. X-ray spectra were fitted to our extensive grids of model atmosphere spectra to determine the effective temperature T_eff on the neutron star surface, logarithm of surface gravity log(g), and the gravitational redshift z simultaneously. We have chosen fitting by numerical model spectra plus broad Gaussian line, modified by interstellar absorption and the absorption on dust. We arbitrarily assumed either hydrogen-helium chemical composition of a model atmosphere, or H-He-Fe mixture in solar proportion. The statistically best values of log(g), and z subsequently were used to determine mass and radius of the neutron star. We obtained the best values of the parameters for the neutron star in X-ray burst source MXB 1728-34: mass either M=0.40 or 0.63 M_sol (for H-He or H-He-Fe models, respectively), radius R=4.6 or 5.3 km, log(g)=14.6 or 14.6 and the gravitational redshift z=0.14 or 0.22. All the above parameters have very wide 1-sigma confidence limits. Their values strongly support the equation of state for strange matter in MXB 1728-34.
