description: By comparing the orbital period distributions of black hole and neutron star low mass X-ray binaries (LMXBs) in the Ritter-Kolb catalogue we show that there is statistical evidence for a dearth of black hole systems at short orbital periods (P_orb < 4h). This could either be due to a true divergence in orbital period distributions of these two types of system, or to black hole LMXBs being preferentially hidden from view at short orbital periods. We explore the latter possibility, by investigating whether black hole LMXBs could be concealed by a switch to radiatively inefficient accretion at low luminosities. The peak luminosity and the duration of X-ray binary outbursts are related to the disc radius and, hence, the orbital period. At short periods, where the peak outburst luminosity drops close to the threshold for radiatively inefficient accretion, black hole LMXBs have lower outburst luminosities, shorter outburst durations and lower X-ray duty cycles than comparable neutron star systems. These factors can combine to severely reduce the detection probability of short period black hole LMXBs relative to those containing neutron stars. We estimate the outburst properties and orbital period distribution of black hole LMXBs using two models of the transition to radiatively inefficient accretion: an instantaneous drop in accretion efficiency (eta) to zero, at a fraction (f) of the Eddington luminosity (L_Edd) and a power-law efficiency decrease, eta \propto \dot{M}^n, for L < f*L_Edd. We show that a population of black hole LMXBs at short orbital periods can only be hidden by a sharp drop in efficiency, either instantaneous or for n >= 3. This could be achieved by a genuine drop in luminosity or through abrupt spectral changes that shift the accretion power out of a given X-ray band.

description: Muon spin spectroscopy is one of the most powerful tools to investigate the microscopic properties of superconductors. In this manuscript, an overview on some of the main achievements obtained by this technique in the iron-based superconductors (IBS) are presented. It is shown how the muons allow to probe the whole phase diagram of IBS, from the magnetic to the superconducting phase, and their sensitivity to unravel the modifications of the magnetic and the superconducting order parameters, as the phase diagram is spanned either by charge doping, by an external pressure or by introducing magnetic and non-magnetic impurities. Moreover, it is highlighted that the muons are unique probes for the study of the nanoscopic coexistence between magnetism and superconductivity taking place at the crossover between the two ground-states.

description: Proliferating cell nuclear antigen (PCNA) is the key regulator of human DNA metabolism. One important interaction partner is p15, involved in DNA replication and repair. Targeting the PCNA–p15 interaction is a promising therapeutic strategy against cancer. Here, a Förster resonance energy transfer (FRET)-based assay for the analysis of the PCNA–p15 interaction was developed. Next to the application as screening tool for the identification and characterization of PCNA–p15 interaction inhibitors, the assay is also suitable for the investigation of mutation-induced changes in their affinity. This is particularly useful for analyzing disease associated PCNA or p15 variants at the molecular level. Recently, the PCNA variant C148S has been associated with Ataxia-telangiectasia-like disorder type 2 (ATLD2). ATLD2 is a neurodegenerative disease based on defects in DNA repair due to an impaired PCNA. Incubation time dependent FRET measurements indicated no effect on PCNA^C148S–p15 affinity, but on PCNA stability. The impaired stability and increased aggregation behavior of PCNA^C148S was confirmed by intrinsic tryptophan fluorescence, differential scanning fluorimetry (DSF) and asymmetrical flow field-flow fractionation (AF4) measurements. The analysis of the disease associated PCNA variant demonstrated the versatility of the interaction assay as developed.

description: We examine how HI and metal absorption lines within low-redshift galaxy halos trace the dynamical state of circumgalactic gas, using cosmological hydrodynamic simulations that include a well-vetted heuristic model for galactic outflows. We categorize inflowing, outflowing, and ambient gas based on its history and fate as tracked in our simulation. Following our earlier work showing that the ionisation level of absorbers was a primary factor in determining the physical conditions of absorbing gas, we show here that it is also a governing factor for its dynamical state. Low-ionisation metal absorbers (e.g. MgII) tend to arise in gas that will fall onto galaxies within several Gyr, while high-ionisation metal absorbers (e.g. OVI) generally trace material that was deposited by outflows many Gyr ago. Inflowing gas is dominated by enriched material that was previously ejected in an outflow, hence accretion at low redshifts is typically substantially enriched. Recycling wind material is preferentially found closer to galaxies, and is more dominant in lower-mass halos since high-mass halos have more hot gas that is able to support itself against infall. Low-mass halos also tend to re-eject more of their accreted material, owing to our outflow prescription that employs higher mass loading factors for lower-mass galaxies. Typical HI absorbers trace unenriched ambient material that is not participating in the baryon cycle, but stronger HI absorbers arise in cool, enriched inflowing gas. Instantaneous radial velocity measures of absorbers are generally poor at distinguishing between inflowing and outflowing gas, except in the case of very recent outflows. These results suggest that probing halo gas using a range of absorbers can provide detailed information about the amount and physical conditions of material that is participating in the baryon cycle.

description: We investigate mean-field dynamics of a nonlinear opinion formation model with congregator and contrarian agents. Each agent assumes one of the two possible states. Congregators imitate the state of other agents with a rate that increases with the number of other agents in the opposite state, as in the linear voter model and nonlinear majority voting models. Contrarians flip the state with a rate that increases with the number of other agents in the same state. The nonlinearity controls the strength of the majority voting and is used as a main bifurcation parameter. We show that the model undergoes a rich bifurcation scenario comprising the egalitarian equilibrium, two symmetric lopsided equilibria, limit cycle, and coexistence of different types of stable equilibria with intertwining attrative basins.

description: Persistent homology probes topological properties from point clouds and functions. By looking at multiple scales simultaneously, one can record the births and deaths of topological features as the scale varies. In this paper we use a statistical technique, the empirical bootstrap, to separate topological signal from topological noise. In particular, we derive confidence sets for persistence diagrams and confidence bands for persistence landscapes.

description: The spectrum averaged cross section (SACS) in standard neutron field is a preferable tool for cross section validation. There are very few measurements involving lutetium neutron cross sections. The presented work uses only neutron standard, i.e., 252Cf(sf) neutron field, for validation of lutetium threshold cross sections. SACS were inferred from gamma spectrometry derived reaction rates. The SACS which were derived include 175Lu(n,2n)174Lu, 175Lu(n,3n)173Lu, 175Lu(n,p)175Yb, and 176Lu(n,n)176m1Lu reactions. All these reactions SACS were measured for the first time. MCNP6 calculations using JEFF-3.3 or ENDF/B-VIII.0 libraries for lutetium cross sections were compared with experimental data. The agreement was found very poor for all reactions under study. Thus there is a need for their improvement. The presented data can be also used for validation of the various theoretical models.

description: Objective: To develop and pilot a web-based patient decision aid (PDA) to support people living with motor neurone disease (plwMND) considering having a gastrostomy tube placed. Methods: In Phase 1, content and design were informed by semi-structured interviews, literature reviews and a prioritization survey. In Phase 2, the prototype PDA was tested with users and developed iteratively with feedback from surveys and ‘think-aloud’ interviews. Phase 1 and 2 participants were plwMND, carers and healthcare professionals (HCPs). In Phase 3, the PDA was evaluated by plwMND using validated questionnaires and HCPs provided feedback in focus groups. Results: Sixteen plwMND, 16 carers and 25 HCPs took part in Phases 1 and 2. Interviews and the literature review informed a prioritization survey with 82 content items. Seventy-seven per cent (63/82) of the content of the PDA was retained. A prototype PDA, which conforms to international standards, was produced and improved during Phase 2. In Phase 3, 17 plwMND completed questionnaires after using the PDA. Most plwMND (94%) found the PDA completely acceptable and would recommend it to others in their position, 88% had no decisional conflict, 82% were well prepared and 100% were satisfied with their decision-making. Seventeen HCPs provided positive feedback and suggestions for use in clinical practice. Conclusion: Gastrostomy Tube: Is it for me? was co-produced with stakeholders and found to be acceptable, practical and useful. Freely available from the MND Association website, the PDA is a valuable tool to support the shared decision-making process for gastrostomy tube placement.

description: Nuclei instance segmentation on histopathology images is of great clinical value for disease analysis. Generally, fully-supervised algorithms for this task require pixel-wise manual annotations, which is especially time-consuming and laborious for the high nuclei density. To alleviate the annotation burden, we seek to solve the problem through image-level weakly supervised learning, which is underexplored for nuclei instance segmentation. Compared with most existing methods using other weak annotations (scribble, point, etc.) for nuclei instance segmentation, our method is more labor-saving. The obstacle to using image-level annotations in nuclei instance segmentation is the lack of adequate location information, leading to severe nuclei omission or overlaps. In this paper, we propose a novel image-level weakly supervised method, called cyclic learning, to solve this problem. Cyclic learning comprises a front-end classification task and a back-end semi-supervised instance segmentation task to benefit from multi-task learning (MTL). We utilize a deep learning classifier with interpretability as the front-end to convert image-level labels to sets of high-confidence pseudo masks and establish a semi-supervised architecture as the back-end to conduct nuclei instance segmentation under the supervision of these pseudo masks. Most importantly, cyclic learning is designed to circularly share knowledge between the front-end classifier and the back-end semi-supervised part, which allows the whole system to fully extract the underlying information from image-level labels and converge to a better optimum. Experiments on three datasets demonstrate the good generality of our method, which outperforms other image-level weakly supervised methods for nuclei instance segmentation, and achieves comparable performance to fully-supervised methods.

Publisher: name: Memorial University of Newfoundland
Year: 2019

description: This thesis offers an ethnographic account of LGBTQ2S tattooing in St. John’s, Newfoundland and Labrador through 19 interviews, four months of participant observation, and a media analysis. Interviews took place with tattooed and non-tattooed LGBTQ2S individuals, and tattoo artists/apprentices, ranging from 20 to 68 years old. Tattoo narratives were collected to understand what it might mean to be LGBTQ2S in St. John’s, in 2018. Research revealed that some LGBTQ2S individuals use tattoos for commemoration, self-expression, and representations of affiliation and group belonging. This thesis explores how some LGBTQ2S individuals use tattoos to visibly represent people, life events, accomplishments, and aspects of their LGBTQ2S identities. Using Brubaker and Cooper’s (2000) reconceptualization of ‘identity’, this thesis discusses participants’ usages of tattooed LGBTQ2S symbols to express elements of their self-understanding. This thesis argues that these uses of tattoos elucidate the importance of visibility for some LGBTQ2S individuals in St. John’s. Drawing on concepts of imagined communities (Anderson 2006) and the symbolic construction of communities (Cohen 1985), this thesis offers a critical discussion of tattoo and LGBTQ2S communities in St. John’s.
The Development of an Individual Competence Assurance Framework at a Major Hazardous Installation

Publisher: name: Cardiff Metropolitan University

Subjects: Occupational and workplace health and safety

description: In 2004 Alpha Hydrocarbon decided to build a new hydrocarbon processing plant at a Greenfield site within the United Kingdom (UK). Given that large quantities of hydrocarbon would be stored and processed by the plant, it was deemed a major hazardous installation, as defined by the Control of Major Accident Hazard Regulations 1999 (COMAH), as amended. One of the key requirements of this COMAH legislation is individual competence assurance. In 2006 it was noted by the Alpha Hydrocarbon senior management team that the development and implementation of the Competence Assurance Framework (ICAF), for all operations-based personnel, had not been executed for some unknown reason. It was evident that Alpha Hydrocarbon needed to embark on a process of planned organisation change, and the Researcher was recruited in the capacity of Management Consultant, in order to develop and implement an ICAF. A pragmatic research philosophy was adopted, this allowed for the use of knowledge to be utilized as a tool for action and change. In order to underpin this pragmatic philosophy I decided on an action research methodology, in order to achieve the desired change agenda within Alpha Hydrocarbon. This action research methodology is imbedded within the thesis structure. Drawing on the wider academic and practitioner literature the thesis examines the development and implementation of the ICAF. From an analysis of relevant literature a model was developed, which encompassed all aspects of individual competence assurance. In order to ensure the ultimate success of the ICAF it was necessary to develop and implement a wide range of learning and development interventions that in essence would underpin and support the developed ICAF. The implementation strategy focused on successfully achieving the desired change agenda in a structured, systematic and measured manner. Finally an evaluation methodology was developed and this was applied to both the development and implementation of the ICAF. The key output was to determine whether operational-based personnel had the correct degree of competence (skills, knowledge, attitude, behaviour), in order to operate a hydrocarbon processing plant facility safely, effectively and efficiently. The developed ICAF is of sufficient generalisability that it could be implemented within industry and commerce alike.

description: Super-Soft-Source (SSS) X-ray spectra are blackbody-like spectra with effective temperatures ~3-7x10^5 K and luminosities of 10^{35-38} erg/s. SSS grating spectra display atmospheric absorption lines. Radiation transport atmosphere models can be used to derive physical parameters, but more sophisticated models are required. We bypass the complications of spectral models and concentrate on the data in a comparative, qualitative study. We inspect all available X-ray grating SSS spectra to determine systematic, model-independent trends. We use comparative plots of spectra of different systems to find common and different features. The results are interpreted in the context of system parameters obtained from the literature. We find two distinct types of SSS spectra which we name SSa and SSe. Their main observational characteristics are either clearly visible absorption lines or emission lines, respectively, while both types contain atmospheric continuum emission. SSe may be obscured SSa systems, which is supported by similarities between SSe and SSa with obscured and unobscured AGN, respectively. Further, we find all known or suspected high-inclination systems to emit permanently in an SSe state. Some sources are found to transition between SSa and SSe states, becoming SSe when fainter. SSS spectra are subject to various occultation processes. In Cal 87, the accretion disc blocks the central hot source when viewed edge on. In novae, the accretion disc may have been destroyed during the initial explosion but could have reformed by the time of the SSS phase. In addition, clumpy ejecta may lead to temporary obscuration events. The emission lines originate from reprocessed emission in the accretion disc, its wind or further out in clumpy ejecta while Thomson scattering allows continuum emission to be visible also during total obscuration of the central hot source.

Subjects: Other human society not elsewhere classified

description: Akan society in Ghana is a covert gynocracy. The Akan Queen Mothers assume a background position despite being co-political rulers of Akan traditional political chieftaincy institutions with sole authority and power for electing a man to be enstooled as king or chief. This background position results directly from traditional cultural and social norms-“cultural politics” -that have existed in Ghana from pre-colonial times to the modern-day and reflect how wider Ghanaian society perceives women.Festivals are extremely important in Ghana with women playing a central role in festival celebrations. One such festival of national and international importance is PANAFEST which celebratesthe ideals of Pan-Africanism. PANAFEST is dominated by men with women, apart from the Queen Mothers,playing a secondary role in the celebrations, only one day focuses on women's activities.This study investigates the implications of covert gynocracy for women's empowerment in Ghana through a case study of women in tourism, particularly PANAFEST,and the role of the Akan Queen Mothers therein.Promoting social harmony rather than gender equality, this post-modern feminist study interprets rich qualitative data generated from unstructured interviews with better-educated individuals and focus group discussions with less well-educated individuals at three PANAFEST destinations.The thesis discusses the structures that underpin Akan society and the power and authority of the Akan Queen Mothers as decision-makers, particularly in respect of kingship. It exposes the contradiction of the Queen Mothers' power and authority with their background position as covert gynocracy and the implications of this for women's empowerment. The thesis presents the Theory of the Giant Leap to encapsulate the enormous challenges for women's empowerment in Ghana through addressing covert gynocracy and male hegemony. The thesis concludes that there is no short-term panacea and that issues can only be addressed in the long-term through education.

description: Several inequivalent definitions of the geometric measure of entanglement (GM) have been introduced and studied in the past. Here we review several known and new definitions, with the qualifying criterion being that for pure states the measure is a linear or logarithmic function of the maximal fidelity with product states. The entanglement axioms and properties of the measures are studied, and qualitative and quantitative comparisons are made between all definitions. Streltsov et al. [New J. Phys 12 123004 (2010)] proved the equivalence of two linear definitions of GM, whereas we show that the corresponding logarithmic definitions are distinct. Certain classes of states such as "maximally correlated states" and isotropic states are particularly valuable for this analysis. A little-known GM definition is found to be the first one to be both normalized and weakly monotonous, thus being a prime candidate for future studies of multipartite entanglement. We also find that a large class of graph states, which includes all cluster states, have a "universal" closest separable state that minimizes the quantum relative entropy, the Bures distance and the trace distance.

description: The separation between single particle levels in nuclei plays the dominant role in determining the location of the neutron drip line. The separation also provides a test of current crossed shell model interactions if the experimental data is such that multiple shells are involved. The present work uses the $^{14}$N(d, p)$^{15}$N reaction to extract the 2s$_{1/2}$, and 1d$_{5/2}$ total neutron single particle strengths and then compares these results with a shell model calculation using a p-sd crossed shell interaction to identify the J$^π$ of all levels in $^{15}$N up to 12.8 MeV in excitation.

description: Multiple myeloma (MM) is an incurable hematological tumor stemming from malignant plasma cells. Similarly to normal plasma cells, MM cells accumulate in the bone marrow (BM) where they establish complex interactions with normal BM stroma, which promote tumor survival and bone disease due to unbalanced bone deposition and resorption. The Notch family of receptors consists of 4 isoforms that, once activated, act as transcription factors. The activation is triggered by membrane-bound ligands (Jagged1-2 and DLL1-3-4). Notch has a key role in the regulation of proliferation, survival, differentiation and stemness in various tissues and tumors. Notch receptors and ligands are deregulated in MM and this signaling system may play a role in the pathogenesis of MM by modulating tumor cell biology, as well as their pathological interactions with the BM niche. Specifically, the myeloma-associated alteration of Notch signaling mainly consists in the aberrant expression of two Notch ligands, Jag1 and Jag2, by tumor cells resulting in Notch signaling activation in both tumor cells and the surrounding cells of the bone niche. Notch mediated signals have been reported to play a role in MM-induced osteoclasts activity and the release of tumor promoting factors by stromal cells. This work unequivocally demonstrates that Notch signaling drives MM cell-induced osteoclastogenesis. The underlying molecular mechanisms is based on: 1) Notch signaling-dependent MM cell ability to promote the release of the osteoclastogenic receptor activator of NF-?B ligand (RANKL), 2) Notch2-mediated transcription of osteoclastogenic master genes, such as Tartrate-resistant acid phosphatase (TRAP) and Receptor Activator of Nuclear Factor ? B (RANK), within osteoclast precursors. Notch2 signaling activation, occurring upon RANKL stimulation, results to be necessary for osteoclastogenesis completion, and further boosts the differentiation by promoting an autonomous secretion of RANKL by osteoclasts. Finally, the most crucial finding of this study is that MM-induced osteoclastogenesis could be disrupted by silencing in MM cells two of the Notch ligands, Jag1 and 2,. These results make Jag1 and Jag2 new promising therapeutic targets to hamper MM-associated bone disease and co-morbidities, lacking the toxicity of the currently used drugs which affects the whole Notch pathway.

description: We perform Monte Carlo simulations based on current age estimates of high-z objects to forecast constraints on the equation of state (EoS) of the dark energy. In our analysis, we use two different EoS parameterizations, namely, the so-called CPL and its uncorrelated form and calculate the improvements on the figure of merit for both cases. Although there is a clear dependence of the FoM with the size and accuracy of the synthetic age samples, we find that the most substantial gain in FoM comes from a joint analysis involving age and baryon acoustic oscillation data.

description: High-dimensional quantum key distribution (HDQKD) offers the possibility of high secure-key rate with high photon-information efficiency. We consider HDQKD based on the time-energy entanglement produced by spontaneous parametric downconversion, and show that it is secure against collective attacks. Its security rests upon visibility data -- obtained from Franson and conjugate-Franson interferometers -- that probe photon-pair frequency correlations and arrival-time correlations. From these measurements an upper bound can be established on the eavesdropper's Holevo information by translating the Gaussian-state security analysis for continuous-variable quantum key distribution so that it applies to our protocol. We show that visibility data from just the Franson interferometer provides a weaker, but nonetheless useful, secure-key rate lower bound. To handle multiple-pair emissions, we incorporate the decoy-state approach into our protocol. Our results show that over 200\,km transmission distance in optical fiber, time-energy entanglement HDQKD could permit a 700 bit/sec secure-key rate, and a photon information efficiency of 2 secure-key bits per photon coincidence in the key-generation phase using receivers with 15% system efficiency.

title: Хоругвь у славян и прагерм. *khrungo
Creators: name: Гаврилов, Александр
Publisher: name: Новгородский государственный университет имени Ярослава Мудрого (НовГУ)
Year: 2020

description: Происхождение слова хоругвь засвидетельствовано в старослав. языке с XIв. как хорѫга, -гъве для перевода греч. σκῆπτρον (‘скипетр, жезл’) и представлено как в славянских, так и в балт. языках, напр. лит. karingas или польск.chorągiew и  chorązy, откуда, опосредованно, русск. ‘хорунжий’.  Со времен научной разработки истории славянской лексики были высказаны различные идеи о происхождении этой по всей видимости заимствованной лексемы, в особенности версии германская и восточная (алтайско-монгольская или собств. тюркская). Учитывая мощное влияние Византии на славянство, можно было начать обзор отсюда, но источника изучаемой лексемы здесь, как будто, не обнаруживается. Мысль о монгольском происхождении лексемы, к которой склонялся М.Фасмер, не утратила своего влияния, хотя вызвала профессиональную критику со стороны ориенталистов; не убеждает и тюркская версия Ф.Миклошича. Что касается германского происхождения лексемы (В.Ягич, Ф.Ф.Браун и др.), то она представляется не только правдоподобной, но и вероятной, так как ее можно подкрепить лингвистическими, культурно-историческими и «реальными» соображениями: древко с воинским значком (готск. hrugga) живет и поныне в германских языках в знач. ‘палка, шесток’ и т. п.; отсюда в соврем. нем. Runge в смысле ‘спица в колесе’, англ. rong. Характерно, что и вошедшее в употреблении в западноевропейских языках обозначение воинского, употребительного в кавалерии «значка», со временем принимает, как и «хоругвь» на прицепленных к древку поверхностях христианские символы, как это видно на позднеантичных штандартах.  Франц. gonfalon также заимствовано из языка германцев <*gundfano, где второй элемент тождествен современному нем. Fahne. Воинственность и вера выступают тут вместе в связи с этим меняющим свой облик и содержание предметом и создают для когда-то простого названия вещи значение символа и атмосферу сугубой святости.
