description: In this thesis I argue that Oliva Sabuco was the author of the New Philosophy of Human Nature, based on the book's medical content as well as her use of language and feminine metaphors. Herein the medical theories of Sabuco are compared with the Canon of Medicine, by Avicenna, and The Controversies, by Francisco Vallés, in order to establish the medical and historical origins of Sabuco's inspiration. The results of this thesis are the following: first, it presents a new perspective related to the concepts of mothers in New Philosophy, that supports the argument in favour of Oliva; second, an identification of the sources in the Canon that are related to the influence of the moon on the humours and liquids of the world; third, a demonstration of how Oliva offers her own solutions to Vallés' polemics, in spite of the fact that Oliva was not formally educated in medicine.

description: Linear gyrokinetic simulations covering the collisional -- collisionless transitional regime of the tearing instability are performed. It is shown that the growth rate scaling with collisionality agrees well with that predicted by a two-fluid theory for a low plasma beta case in which ion kinetic dynamics are negligible. Electron wave-particle interactions (Landau damping), finite Larmor radius, and other kinetic effects invalidate the fluid theory in the collisionless regime, in which a general non-polytropic equation of state for pressure (temperature) perturbations should be considered. We also vary the ratio of the background ion to electron temperatures, and show that the scalings expected from existing calculations can be recovered, but only in the limit of very low beta.

description: The far ultraviolet (FUV) continuum flux is recognized as a very sensitive diag- nostic of the temperature structure of the Sun's lower chromosphere. Until now analysis of the available stellar FUV data has shown that solar-type stars must also have chromospheres, but quantitative analyses of stellar FUV continua require far higher quality spectra and comparison with new non-LTE chromosphere models. We present accurate far ultraviolet (FUV, 1150-1500^{\circ}) continuum flux measurements for solar-mass stars, made feasible by the high throughput and very low detector background of the Cosmic Origins Spectrograph (COS) on the Hubbble Space Telescope. We show that the continuum flux can be measured above the detector background even for the faintest star in our sample. We find a clear trend of increasing continuum brightness temperature at all FUV wavelengths with decreasing rotational period, which provides an important measure of magnetic heating rates in stellar chromospheres. Comparison with semiempirical solar flux models shows that the most rapidly rotating solar-mass stars have FUV continuum brightness temperatures similar to the brightest faculae seen on the Sun. The thermal structure of the brightest solar faculae therefore provides a first-order estimate of the thermal structure and heating rate for the most rapidly rotating solar-mass stars in our sample.

Effectiveness of urinary tract infection self-assessment tool-ACSS in adult female population at primary care outpatient clinic in New Jersey
Creators: name: Panagar, Joanna M.
Publisher: name: No Publisher Supplied
Year: 2020

description: Project Purpose: Urinary tract infection (UTI) is one of the most commonly occurring infection in the outpatient care setting that requires antibiotic treatment. Postmenopausal females have a substantially higher risk of developing UTIs due to hormonal changes occurring in the body. This study will be conducted to evaluate the effectiveness of the Acute Cystitis Symptom Score (ACSS) questionnaire in self symptom-reporting by the patient. The study will utilize information on UTI symptoms and treatment guidelines to provide education and promote patient self-efficacy in reporting UTI symptoms in a standardized manner using the ACSS tool. Methodology: This pilot study used a pre- and post-test design to assess the effectiveness of symptom-reporting by utilizing the ACSS in the outpatient care setting. Differences in the typical, differential, and quality of life scores pre- and post-treatment were assessed using the Wilcoxon Rank Sum test, with significance set at p-value <0.05. Results: Among the participants, there were significant reductions in symptoms at initial and follow-up visits. Most of the participants had either no symptoms or mild symptoms at follow-up as compared to the initial visits when they had mild and moderate symptoms. Also, most of the respondents had either no or mild affectation of their quality of life at the follow-up visits compared to the initial visit when they reported moderate, and extreme affectation.Implications for Practice:The ACSS tool could be used in the primary care setting to standardize the reporting of the UTI symptoms by the female patients.

description: In this paper, we investigate the problem of mining numerical data in the framework of Formal Concept Analysis. The usual way is to use a scaling procedure --transforming numerical attributes into binary ones-- leading either to a loss of information or of efficiency, in particular w.r.t. the volume of extracted patterns. By contrast, we propose to directly work on numerical data in a more precise and efficient way, and we prove it. For that, the notions of closed patterns, generators and equivalent classes are revisited in the numerical context. Moreover, two original algorithms are proposed and used in an evaluation involving real-world data, showing the predominance of the present approach.
title: Image-based Semantic Segmentation of Large-scale Terrestrial Laser Scanning Point Clouds
Creators: name: Cai, Yuanzhi
Publisher: name: University of Liverpool Repository
Year: 2023

description: Large-scale point cloud data acquired using terrestrial laser scanning (TLS) often need to be semantically segmented to support many applications. To this end, various three-dimensional (3D) methods and two-dimensional (i.e., image-based) methods have been developed. For large-scale point cloud data, 3D methods often require extensive computational effort. In contrast, image-based methods are favourable from the perspective of computational efficiency. However, the semantic segmentation accuracy achieved by existing image-based methods is significantly lower than that achieved by 3D methods. On this basis, the aim of this PhD thesis is to improve the accuracy of image-based semantic segmentation methods for TLS point cloud data while maintaining its relatively high efficiency. In this thesis, the optimal combination of commonly used features was first found, and an efficient manual feature selection method was proposed. It was found that existing image-based methods are highly dependent on colour information and do not provide an effective means of representing and utilising geometric features of scenes in images. To address this problem, an image enhancement method was developed to reveal the local geometric features in images derived by the projection of point cloud coordinates. Subsequently, to better utilise neural network models that are pre-trained on three-channel (i.e., RGB) image datasets, a feature extraction method (LC-Net) and a feature selection method (OSTA) were developed to reduce the higher dimension of image-based features to three. Finally, a stacking-based semantic segmentation (SBSS) framework was developed to further improve segmentation accuracy. By integrating SBSS, the dimension-reduction method (i.e. OSTA) and locally enhanced geometric features, a mean Intersection over Union (mIoU) of 76.6% and an Overall Accuracy (OA) of 93.8% were achieved on the Semantic3D (Reduced-8) benchmark. This set the state-of-the-art (SOTA) for the semantic segmentation accuracy of image-based methods and is very close to the SOTA accuracy of 3D method (i.e., 77.8% mIoU and 94.3% OA). Meanwhile, the integrated method took less than 10% of the processing time (52.64s versus 563.6s) of the fastest SOTA 3D method.

description: Poverty is a situation or circumstance in which an individual or society lacks the financial services and necessities for a minimum standard of life. Poverty implies that the income standard from work is so low that essential human requirements can't be fulfilled. Poverty-stricken individuals and families might go without adequate shelter, safe water, nutritious food, and medical care. This study aims to assess the factors that might contribute to the quality of life of the respondents. Thus, its' purpose was to describe the demographic profile of the residents of the partner community of St. Paul College of Bocaue. The respondents of the study were the community in a slum area in Bulacan, Philippines. The descriptive research method was utilized to describe the respondents' gender, age of parents, marital status, number and age of siblings, educational attainment, job classifications, employment status, religion and Catholic faith manifestation. A total of fifty-five (55) families of the partner community participated in this study. Based on the survey, the following are the study's significant findings: Most of them are engaging in a lived-in relationship that results in teenage pregnancy. Thus, most of the respondents have low educational attainment and unemployed.
Making a Living in Trinidad: An Ethnographic Exploration of Entrepreneurial Learning among Youth

description: This thesis explores how certain entrepreneurial skills and knowledge are transmitted to Trinidadian youth through family and educational programs. On one hand, government initiatives direct unemployed youth back into the labour market through entrepreneurship education. On the other hand, many youth attending these institutions are already employed, and have pre-existing businesses. This invites reflection on how youth are learning about entrepreneurship outside of formal training, and why they are choosing to pursue formal training anyway. Based on ethnographic fieldwork in Trinidad, this thesis demonstrates that young entrepreneurs engage in both the measured pursuit of profit and the fulfillment of other culturally meaningful desires, and that these internal motivations are influenced by external sources of knowledge and social interactions. Drawing on the literature on economic anthropology, I agree that youth are learning about entrepreneurship from families, and argue that such learning can be effectively supported via public policy and educational institutions.

description: The effects of polymer concentration and chain length on aggregation in associative polymer solutions, are studied using self-consistent field lattice model. Only two inhomogenous morphologies, i.e. microfluctuation homogenous (MFH) and micelle morphologies, are observed in the systems with different chain lengths. The temperatures at which the above two inhomogenous morphologies first appear, which are denoted by T_MFH and T_m, respectively, are dependent on polymer concentration and chain length. The variation of the logarithm of critical MFH concentration with the logarithm of chain length fulfils a linear-fitting relationship with a slope equaling -1. Furthermore, the variation of the average volume fraction of stickers at the micellar core (AVFSM) with polymer concentration and chain length is focused in the system at T_m. It is founded by calculations that the above behavior of AVFSM, is explained in terms of intrachain and interchain associations.

Social identity, agency, and the politics of adherence to antiretroviral therapy in HIV/AIDS care
Creators: name: Berkhout, Suze Gillian
Publisher: name: University of British Columbia
Year: 2010

description: Within Vancouver’s Downtown Eastside community, gendered disparities exist with respect to uptake and continuity of antiretroviral therapy; limited access and adherence to therapy is commonly reported in the medical literature concerning women in the community. These findings are particularly hard to reconcile, as HIV treatment exists amidst a range of neighbourhood health and social support services that are ostensibly accessible to all through a universal health care system. In this dissertation, I examine conventional approaches to facilitating treatment uptake and adherence along with dominant narratives employed to explain treatment challenges faced by women in Downtown Eastside Vancouver. Bringing together discourse analysis, qualitative interviewing, and participant observation with HIV-positive women and their health care providers I propose an alternate lens with which to examine gender disparities in HIV care. I argue that discourses of adherence to antiretroviral therapy are suffused with cultural imagery and tropes associated with women at high risk of HIV infection: images of sex work, drug use, homelessness, and mental illness. Additionally, an individualist, rationalist bias exists within much of the North American literature regarding women’s access and adherence to care; the literature finds points of convergence with larger normative frameworks of liberalism within medical practices. Contrary to a conventional emphasis on psychosocial “barriers” to care, I focus on social interests, institutional authorities, relations of power, and strategies of social control. These are exerted on, resisted, and internalized by women attempting to negotiate care. I also suggest how a normative liberal framework underpinning HIV research and care may have the inadvertent consequence of further entrenching images of HIV positive women as deviant, dangerous, and/or irrational. My reframing issues of access and adherence as matters of negotiation and negative agency leads me to discuss the ways in which liberal conceptions of autonomous agency are employed within discourses of HIV/AIDS care, structuring health care decision making and possible courses of action. The arguments I offer endorse a constitutively relational account of the self and autonomy. A relational account can, I argue, provide insight and guidance concerning adherence to antiretroviral therapy.

subject: Clinical Teaching, Medical student, Clinical Teacher, learning in clinical setting,

description: Clinical teaching of medical students is vital to prepare them for effective patient management and future practice. In turn, it is important for teachers to recognize the factors that influence learning (i.e., principles) along with the processes that underlie them (i.e., theories). This is expected to promote student learning and facilitate student achievement, future practice and lifelong learning. This study focuses on the effectiveness of the clinical teacher in a clinical teaching setting, through the statistical and empirical investigation of a model representing the relationship between teacher characteristics, student perceptions and student outcomes. This study was carried out in clinical settings in one medical school in Saudi Arabia. The study focused on two research questions: First, if there is there a relationship between teacher characteristics (input), student perceptions (process) and student assessment (outcome) factors in clinical teaching. Second, if a latent variable path model can be developed to demonstrate the relationship between teacher characteristic, student perception and student outcome. This study developed and tested a theory-based model using structural equation modeling. It evaluated clinical teaching by taking into consideration three levels: (1) input factors including teacher characteristics, (2) process factors focusing on student perceptions, and (3) outcome factors addressing student achievement. Data were gathered from clinical teachers as well as medical students. The results showed a significant relationship between teacher characteristics, student perceptions and student outcomes in clinical teaching. A latent variable path analysis showed a good fit to the data with a comparative fit index of .93, which converged in 7 iterations, with a standardized residual mean error of 0.05 and RMSEA of 0.08, SRMR = 0.05. To our knowledge this is the first study in the medical education literature that analyzed and demonstrated a perfect fit of the tested three level theoretical model (teacher characteristics, teaching and coaching skills and student outcomes) and empirical data using Structural Equation Modelling. It is proposed that future research studies identify and test additional factors that may influence student outcomes in a clinical setting.

description: This work investigates the use of an optical tomography system as a non-intrusive measurement tool for the study of horizontal multiphase flow. Dispersed bubble flow of water and air is captured with a set of three high-speed video cameras. Bubble position data is reconstructed from the cameras's images to analyze its structure inside the pipe. Three pipe diameters are used and a set of different Reynolds numbers are chosen at two investigation points along the pipe. Commonly, multiphase flows are studied using a top-view imaging technique. Thus, in order to assess the capability of the tomographic system to measure flow properties, a comparison between top-view imaging and tomography is performed. The 3D tomography data is also used to characterize the flow of bubbles. A statistical analysis of the sizes, velocities, positions and shapes is presented.

description: We report a comprehensive experimental and theoretical study of the quasi-one-dimensional quantum magnet CuNCN. Based on magnetization measurements above room temperature as well as muon spin rotation and electron spin resonance measurements, we unequivocally establish the localized Cu+2-based magnetism and the magnetic transition around 70 K, both controversially discussed in the previous literature. Thermodynamic data conform to the uniform-spin-chain model with a nearest-neighbor intrachain coupling of about 2300 K, in remarkable agreement with the microscopic magnetic model based on density functional theory band-structure calculations. Using exact diagonalization and the coupled-cluster method, we derive a collinear antiferromagnetic order with a strongly reduced ordered moment of about 0.4 mu_B, indicating strong quantum fluctuations inherent to this quasi-one-dimensional spin system. We re-analyze the available neutron-scattering data, and conclude that they are not sufficient to resolve or disprove the magnetic order in CuNCN. By contrast, spectroscopic techniques indeed show signatures of long-range magnetic order below 70 K, yet with a rather broad distribution of internal field probed by implanted muons. We contemplate the possible structural origin of this effect and emphasize peculiar features of the microstructure studied with synchrotron powder x-ray diffraction.

Opioid use treatment waitlist effects on engagement
Creators: name: Pettyjohn, Faith
Publisher: name: No Publisher Supplied
Year: 2020

description: Purpose of Project: Opioid use disorder is a chronically relapsing disorder requiring multiple attempts with treatment: that is why the ability to access treatment is so important. Barriers for accessing treatment directly impact outcomes due to higher risks for mortality and discouragement of seeking treatment. Wait time is a commonly studied barrier associated with unsuccessful treatment entry. Wait times can average a month or more for treatment entry. The purpose of this project was to explore the relationship between opioid use treatment waitlist experience and treatment outcomes.Methodology: This correlational pilot project took place in a small outpatient medication assisted treatment program in an urban city in New Jersey. A total of 25 male and female participants at least 18 years of age were recruited. Participants engagement was recorded across 30 days. The outcome measures included waitlist, resilience, and engagement. A waitlist survey examined the number of waitlist occurrence, denial of treatment entry, and feelings of depression and anxiety. Self-esteem, self-efficacy, intellect, religiosity/spirituality, optimism, and family support were used as factors for measuring resilience. Treatment engagement included urine toxicology screens and group attendance. Results: Due to the COVID-19 pandemic participant recruitment was halted and there was a decrease in participant engagement. Most of the participants had at least one experience of delayed treatment entry. Nearly all participants reported experiencing depression, anxiety, withdrawal, or no cessation of opioids while waiting to enter treatment. Implications for Practice: In order to effectively improved outcomes as an Advanced Practice Nurse treating individuals with opioid use disorder the following nursing practices will be beneficial; obtaining a waiver to practice opioid dependency treatment, monitoring signs and symptoms of anxiety and depression, targeting women in treatment for retention purposes, retraining resilience skills, and meeting individuals were they are by using harm reduction as a model for participants who are having difficulties with buprenorphine compliance.

description: Solar thermal water heating is a major application of renewable energy. Canada’s renewable energy utilization is very low in fulfilling its hot water demands. Though Alberta has a good solar energy potential, it is seldom used. Possibly the biggest application is the solar thermal system with 150 evacuated tube collectors (ETCs) which was installed by the City of Calgary on the roof of the Southland Leisure Centre (SLC). The system pre-heats the swimming pool water. Expansions of City of Calgary’s solar thermal water heating may well depend on the performance of the SLC system. Important parameters of two collectors in the system were measured to compute efficiency during seven months. Among them, global solar radiation indicated the total energy received by the collectors. The wind speed and direction used to assess the convective heat transfer losses. Panel inlet and outlet temperatures and flow rate of working fluid provided the useful energy absorbed. Ambient temperature was recorded to estimate temperature rise of the collector. A data logger monitored the solar radiation and wind while a special purpose monitoring system collected temperatures and flow rate. The efficiency of the collectors was computed based on steady and unsteady state energy balances. Experiment data were compared with the efficiency data measured by the Fraunhofer Institute (Germany) for the same collector type according to the appropriate international standard. Performance indicators were unsteady efficiency and the ratio of Unsteady/Steady terms in the energy equation. Unsteady state efficiency was very low compared to the international test standard and the ratio of Unsteady/Steady was very high. It was concluded that the operating efficiency of collectors is lower than the expected efficiency and the unsteady factors are dominant in the system.

description: Single motherhood is now becoming a "norm," the number of single mothers has been steadily increasing for so many reasons such as giving birth outside marriage, separation, divorce, annulment, the death of a partner, or simply because some women chose to have a child and stay single. The study explored the lived experiences of single mothers in raising their children. Thus, the study aims to determine how single mothers cope with their situation to provide improved life to their children and themselves. The researchers have employed qualitative research methodology. The fundamental question is, what are the lived experiences of single mothers in childrearing practices? The study's findings revealed that financial problems (struggles in meeting the basic needs of the children/family) and loneliness as the predominant feeling among single mothers are the common problems and experiences of being a single mother. Faith, support from family and community, and their job play an essential role in coping with their situation and helping them survive. It made them feel suitable for themselves, and they were trustworthy and independent in raising their children as single mothers. The study also suggests a need to recognize the struggles of single mothers and their children and call for interventions by both government and social workgroups to help them cope with single parenthood's financial, psychological, and emotional challenges.

description: Two features in time series data: the existence of time trends and the degree of persistence, are examined in this work on the nitrogen oxides emissions from 37 OECD countries. Updated techniques in time series are used that allow for fractional degrees of differentiation in the data. Thus, if the number of differences required is one, nitrogen oxides emissions are not mean reverting in the sense that if there is an exogenous shock (resulting from a technological advancement to change nitrogen oxides emissions), the effect of such shock on nitrogen oxides emissions will be permanent. Time trends are observed in half of the series. For these countries the trend coefficient is found to be positive in all cases. This is an indication that continuous technological progress is needed in taming NOx emissions. In addition to developing their own local technologies, less technologically endowed OECD countries should engage in collaboration with the more technologically endowed countries in order to facilitate increase in trans-border transfer of technology. The technologically advanced countries should also strive to continue to introduce better technologies in a bid to reduce NOx emissions. Most of the results show evidence for persistence of nitrogen oxides emissions.

description: Glorious victories have been achieved when quantum theory (QT) is applied to microscopic systems. However, although there might be good reasons for us to believe that QT applies at the macroscopic level as well, to give a definite answer ”yes” there is still a long journey. If it does apply, a direct result is that it predicts highly counter-intuitive macroscopic quantum superpositions and entanglements, which we never experience in our daily lives. In this thesis we assume that QT applies to the macroscopic level, and try to find out why we never really observe macroscopic quantum effects. The thesis contains two projects, aiming at two reasons for the above problem. In the first project (Chapter 3 and 4), we show that the required resolution to observe macroscopic quantum effects increases with the size of the system, when both outcome precision and control precision are taken into account. This means that for really large quantum effects we need a very good measuring resolution to observe them, while what we usually do are coarse-grained measurements, whose resolutions are much lower. In the second project (Chapter 5), we try to deal with decoherence, another obstacle preventing us from observing macroscopic quantum effects. We propose to create and detect strong entanglement of micro-macro and macro-macro beams of photons with very weak cross Kerr nonlinearities that are obtainable by current technology. We analyze the entanglement under environmental decoherence with various methods, and show that strong entanglement can still be created and detected under decoherence. We hope that the above results will help to push the boundary of the realm of QT towards the macroscopic level.

The resulting surface plasmon-polaritons are responsible for a substantial increase of electromagnetic radiation absorption by the graphene sheet. The origin of the modulation can be due either to a periodic strain field or to adatoms (or absorbed molecules) with a modulated adsorption profile.

description: Purpose of Project: The purpose of the study was to evaluate the usefulness of the aromatherapy (AT) recommendation in the American Holistic Nurses Association’s (AHNA) Holistic Nurses' Pain Relief Tools for Patients & Self-Care (Pain Tool). Survey results were analyzed to make recommendations to AHNA on the current state of the Pain Tool and how it may be improved.Methodology: An observational survey design was used and a purposeful sample of 55 nurses were invited to a two-part, 15 question survey administered via SurveyMonkey. The demographic data was analyzed with quantitative analysis and the open-ended questions were analyzed via content analysis. Results: A total of 55 participants completed the survey and the mean age was 53 years old. The participants learned about the Paint Tool from the AHNA website (62%; n= 34) and publications (56%; n= 31). Lavender essential oil (EO) was used by 100% (n= 55) of participants. Over half, (65%; n= 17) of participants used EOs for pain relief. The inhalation method was favored (93%; n=51) due to institutional policy and procedure (67%; n=6) and ease of use (44%; n=4). The recommendation was most helpful for educational purposes (29%; n=16) and to reduce symptoms of pain (21%; n=8). A majority of participants used the five holistic nursing core values (70%; n=31) as well as promote more options for pain management (48%; n=13) to improve outcomes (30%; n=13). More than half of the respondents (54%; n=19) felt that the recommendation did not require changes, but some participants (23%; n=8) did recommend that AHNA add more essential oils and safety information (23%; n=8). Finally, recommendations were made to AHNA based on the outcomes. Implication for Practice: Nurses who use AT as a safe, cost-effective intervention for pain improve quality outcomes. Clinical practice guidelines may add AT as part of a multi-modal approach to pain management and institutions may use the Pain Tool as an addition to their protocols. Lastly, as more nurses use the Pain Tool and lead institutional policy changes to include AT for pain, nursing education may begin standardizing curricula with AT instruction. Further studies on safe methods of administration in COVID-19 are recommended.

description: Purpose: To assess perinatal nurses' attitudes toward technology, use, and readiness to use telehealth in practice.Methodology: Online survey invitation to 6,000 New Jersey State Nurses Association members. Descriptive statistics to analyze findings. Results: 52 perinatal nurses participated in the survey for a 25% response rate. 42% (n=22) completed the 90 question survey. Partial answers were included in the analysis. 62% worked in hospitals and workplaces with less than 50 people. 64% (n=26) used started or expanded telehealth since the pandemic and primarily used video telehealth (66%, n=23). Nurses reported that they felt that technology was a necessary skill (77%, n=23) and disagreed 63% (n=20) disagreed or strongly disagreed that technology made them feel nervous and there was no statistical significance when looking at those under 45 and those over 45, U=(Nunder 45=15, Nover45=17) = 11. z=-0.02, p < 0.83. The Telehealth Readiness Assessment has 52 questions. Of questions that were answered, the mean=26.4, median=25, mode=24, min=24, max=31. Aggregate survey data entered to complete the Telehealth Readiness Assessment Tool. The overall score was almost ready. Domain scores were: core readiness = ready, financial considerations = area of improvement, operations = about ready, staff engagement = almost ready and patient readiness = almost ready.Implications for Practice: Perinatal telehealth is a new service model in New Jersey and can be a tool to reach a vulnerable population. Clinical practice is significantly impacted by telehealth and can provide new opportunities for growth and patient satisfaction. Assessing readiness is an essential step in implementation. State and federal policies need to ensure telehealth infrastructure and investment with an equity lens. Safety and quality must be assured with appropriate guidelines, training, and support. Financial payment parity will be required for sustainability. Nursing education from entry-level to experienced nurse need to reinforce best practices in effective communication, teamwork, and leadership.
Bipartite entanglement, spherical actions and geometry of local unitary orbits

description: We use the geometry of the moment map to investigate properties of pure entangled states of composite quantum systems. The orbits of equally entangled states are mapped by the moment map on coadjoint orbits of local transformations (unitary transformations which do not change entanglement), thus the geometry of coadjoint orbits provides a partial classification of different entanglement classes. To achieve the full classification a further study of fibers of the moment map is needed. We show how this can be done effectively in the case of the bipartite entanglement by employing Brion's theorem. In particular, we presented the exact description of the partial symplectic structure of all local orbits for two bosons, fermions and distinguishable particles.

description: The exact composition of a specific class of compact stars, historically referred to as "neutron stars", is still quite unknown. Possibilities ranging from hadronic to quark degrees of freedom, including self-bound versions of the latter have been proposed. We specifically address the suitability of strange star models (including pairing interactions) in this work, in the light of new measurements available for four compact stars. The analysis shows that these data might be explained by such an exotic equation of state, actually selecting a small window in parameter space, but still new precise measurements and also further theoretical developments are needed to settle the subject.

description: Background: That there have been ‘long waves’ of consumption in parallel in different societies has previously been noted. Now there is a sustained drop in drinking among youth in most of Europe, Australia and North America. Can such changes be understood in a common frame? In terms of inexorable historical phenomena or forces, like Kondratieff waves? In terms of generational shifts, with a younger generation reacting against the habits of an older? Method: Such conceptual models for understanding the dynamics of social change are examined in terms of their potential contribution in explaining when and how substantial changes in levels of consumption occur roughly in concert in different societies, with particular reference to the decline in drinking and heavy drinking in current youth cohorts. Results and Conclusion: Timing tends to rule out economic change as a factor in the current widespread decline in youth drinking. The technological revolution of the electronic web and the smart phone seems a primary explanation, with the widespread change in social presentation and interaction — in habitus — between parents and children also involved. Directions for further research are suggested.
