PointNet with Spin Images

Machine learning on 3D point clouds is challenging due to the absence of natural ordering of the points. PointNet is a neural network architecture capable of processing such unordered point sets directly, which has achieved promising results on classiﬁcation and segmentation tasks. We explore methods of utilizing point neighborhood features within PointNet and their impact on classiﬁcation performance. We propose neural models that operate on point clouds accompanied by point features. The results of our experiments suggest that traditional spin image representations of point neighborhoods can improve classi-ﬁcation eﬀectiveness of PointNet on datasets comprised of objects that are not aligned into canonical orientation. Furthermore, we introduce a feature-based alternative to spatial transformer, which is a sub-network of PointNet responsible for aligning misaligned objects into canonical orientation. Additional experiments demonstrate that the alternative might be competitive with spatial transformer on challenging datasets.
Coherent dusty and gaseous structures near the Galactic center

Sagittarius A*, a compact source in the centre of the Milky Way, is the nearest supermassive black hole (SMBH) in our cosmic neighbourhood, where various astrophysical processes take place. In consequence, variety of structures emerge near the Galactic centre and bow shocks that are closely studied in this work represent an example of them. The introductory part of this thesis is a brief review of the history of the Galactic centre research and its discovery in radio wavelengths. The main body of the thesis is focused on a simplified model of the bow-shock structures that are generated by stars moving supersonically with respect to the ambient medium. We discuss how these structures vary along the orbit. To this end, we consider four different models: (a) without the presence of any gaseous medium emerging from or accreting onto the SMBH, (b) taking an outflow from the SMBH into account, (c) the case of an inflow onto the SMBH, and finally (d) the combined model involving both an outflow and an inflow at the same time. We discuss symmetries of each model (or lack of them) and we find that the model considering the ambient medium at rest appears symmetrical with respect to the pericentre passage. The combined model manifests itself as the most asymmetrical one of them all. We show profiles for the tangential velocity in the shell and the mass surface density of the bow-shock shell along the stellar orbit for all considered models.

Conflicts of interest: there is no conflict of interest to declare. Abstract Objective: To learn how nurses perceive their professional activity and what are their expectations concerning the development of comprehensive care management. Methods: Qualitative research with Alfred Schütz’s social phenomenology approach. The participants were nine female nurses who worked at public and private hospitals in Montevideo, Uruguay. Results: The nurses experience the gap between theory and practice, administrative overload, insecurity to take over care management and pursuit of formal and informal knowledge; they show desires and specific definitions, autonomy and professional identity, and professional valuation. Conclusion: The nurses perceive their professional activity as having a gap between theory and practice, administrative overload, insecurity to take over care management and pursuit of formal and informal knowledge, with expectations and desires of recovery and definitions of specific duties, autonomy and professional identity.
Extracorporeal Membrane Oxygenation for Near-Drowning Victims

Background: Drowning is the leading cause of death in children worldwide. Likewise, the survival rate of adults found in cardiac arrest by emergency medical personnel after a drowning event is 1.7%. Sequelae attached to near-drowning events are highly varied in type and severity and are often proportional to stretch of anoxia and liquid volume aspirated. Extracorporeal membrane oxygenation is a form of cardiopulmonary bypass allowing heart and/or lung rest post insult by artificially oxygenating, removing CO2 waste, and rewarming blood. Method: An exhaustive search using MEDLINE-Ovid, Web of Science, and CINAHL was performed using keywords: extracorporeal membrane oxygenation and drowning. These were screened with eligibility criteria. The resulting studies were then appraised and assessed for quality with GRADE. For ethical reasons no prospective, randomized and controlled human studies are available thus all data are derived from retrospective observational studies or individual case reports. Results: Fifty articles were reviewed for relevance; two retrospective observational studies and two case reports were identified fitting the question under investigation. Due to the nature of the question posed, the quality of the evidence was very low, but one study and both case reports showed a resulting benefit to early intervention with ECMO post near-drowning incident. The second study had the added confounder of each patient suffering moderate too severe hypothermia thus making a conclusion difficult due to relatively high mortality. Conclusion: Due to the complex nature and high mortality rate of near-drowning victims, ECMO can be used safely and effectively as an adjunct resuscitative strategy for select patients with cardiac and/or pulmonary failure and hypothermia resistant to conventional therapies.
Useful Mutations Violate Invariants — Equivalent Mutants do not

Mutation testing measures the adequacy of a test suite by seeding artiﬁcial defects (mutations) into a program. If a mutation is not detected by the test suite, this usually means that the test suite is not adequate. However, it may also be that the mutant keeps the program’s semantics unchanged— and thus cannot be detected by any test. Such equivalent mutants have to be eliminated manually, which is a tedious task. We assess the impact of mutations by checking dynamic invariants. In an evaluation of our JAVALANCHE framework on seven industrial-size programs, we found that mutations that violate invariants are signiﬁcantly more likely to be detectable by a test suite. As a consequence, mutations with impact on invariants should be focused upon when improving test suites. With less than 3% of equivalent mutants, our approach provides a precise and fully automatic measure of the adequacy of a test suite.
First Aid Training Program for Mothers of Blind Children

Injuries are a common problem among blind and visually impaired children, therefore first aid measures for blind children must be performed properly to prevent further complications and potentially saving their life. This study aimed to evaluate the effect of a first aid training program for mothers of blind children. A research design that used was a quasi-experimental study. Setting: The study was carried out at the Model Centre for the Care and Guidance of the Blind, affiliated to the Ministry of Social Solidarity. Sample All mothers accompanying their blind children (42 mothers) who were attended in the previously mentioned setting over 6 months period. For data collection one tool was used; a structured interviewing questionnaire to assess the blind children and their mothers' demographic characteristics, mothers' knowledge and reported practices related to first aid for injuries. Results of the study revealed that; wounds, dislocation, fractures, and epistaxis are the most common injuries that occurred among blind children. There were statistically significant differences between pre/post the first aid training program related to mothers’ total knowledge about first aid to injuries, where about three-quarters of studied mothers had unsatisfactory total knowledge pre program compared to slightly more than a quarter of them had unsatisfactory total knowledge post-implementation. Additionally, the majority of studied mothers had inadequate total reported practices pre program compared to more than twothirds of them had adequate total reported practices post-implementation Conclusion: The first aid training program led to significant improvement in the knowledge and practices of studied mothers related to injuries and first aid measures applied for their blind children. Recommendation: Health education program must be conducted for mothers of blind children on injuries prevention and first aid measures as a routine service at all rehabilitation centers of the blind children.

Achados à prova calórica e canal semicircular acometido na vertigem posicional paroxística benigna Caloric test results and damaged semicircular canal in benign positional paroxysmal vertigo

PURPOSE: To characterize caloric test results in benign paroxysmal positional vertigo patients, according to the damaged semicircular canal. METHODS: The data of 1033 patients submitted to Dix-Hallpike testing, positional nystagmus and electronystagmography were analyzed. Caloric test results were compared to the damaged semicircular canals and were submitted to statistical analysis. RESULTS: In cases with posterior canal damage, there was prevalence of normal responses compared to abnormal results (p<0.0001); hypo activity was more prevalent than hyperactivity (p<0.0001) and directional preponderance (p<0.0001), and hyperactivity more prevalent than directional preponderance (p<0.0001). In cases with lateral canal damage, normal responses were more prevalent than hypo activity (p<0.0001) and hyperactivity (p<0.0001); there was a tendency of prevalence of hypo activity over hyperactivity (p=0.0771), and directional preponderance was not observed. In cases with anterior canal damage, normal responses were more prevalent than hypo activity (p<0.0001); hyperactivity and directional preponderance were not observed. CONCLUSION: In the caloric test of benign positional paroxysmal vertigo patients, normal responses, hypo activity, hyperactivity or directional preponderance of post-caloric nystagmus occur in decreasing order of prevalence when the posterior canal is damaged; normal responses are more prevalent than hypoactive or hyperactive caloric responses, and there is a tendency of prevalence of hypoactive over hyperactive caloric responses when the lateral canal is damaged; normal responses are more prevalent than hypoactive caloric responses when the anterior canal is damaged.
Sound Traditional and Nontraditional Prepartum Exercise for Good Health

There has been a progressive evolution in the concept of exercise for prepartum women. Per contra, screening guidelines have not changed. All women should have a thorough clinical evaluation by the health care team before an exercise program is recommended. This is true for previously sedentary women or women who have been active before their pregnancy. The consensus today is that given no medical contraindications to exercise during pregnancy women with uncomplicated pregnancies should participate in moderate exercise, such as brisk walking, 30 min a day or more. The use of heart rate to guide intensity is not valid for prepartum women because of the large variability of heart rate during pregnancy. Rather, metabolic equivalents (METS), the Rating of Perceived Exertion Scale (RPE) or methods such as the talk test should be used to monitor exercise intensity. The recommendation is 3-5 METS, an RPE of 12-14 (somewhat hard) on the 6-20 scale, or women should be able to maintain a conversation while exercising. Strength-conditioning activites are also advocated in uncomplicated pregnancies. However, there is less evidence on strength conditioning and weight training in pregnancy. The research on yoga and Plates on gravid women is too limited to make a position stand on these activities. Regardless of the type of activity, all goals should be reasonable. Furthermore, pregnancy it is not a time to reach peak fitness levels or train for an athletic competition. Elite athletes who train during pregnancy require supervision by an obstetric care provider with knowledge of the impact of strenuous exercise on fetal outcomes.
Federal Reserve Bank of Minneapolis Research Department Staff Report 363 Does Income Inequality Lead to Consumption Equality? Evidence and Theory

Using data from the Consumer Expenditure Survey, we first document that the recent increase in income inequality in the United States has not been accompanied by a corresponding rise in consumption inequality. Much of this divergence is due to different trends in within-group inequality, which has increased significantly for income but little for consumption. We then develop a simple framework that allows us to analytically characterize how within-group income inequality affects consumption inequality in a world in which agents can trade a full set of contingent consumption claims, subject to endogenous constraints emanating from the limited enforcement of intertemporal contracts (as in Kehoe and Levine, 1993). Finally, we quantitatively evaluate, in the context of a calibrated general equilibrium production economy, whether this setup, or alternatively a standard incomplete markets model (as in Aiyagari, 1994), can account for the documented stylized consumption inequality facts from the U.S. data. * We thank the editor, Fabrizio Zilibotti, three anonymous referees, and seminar participants at numerous institutions and conferences for their many and very helpful comments.

Hardware implementations of computer-generated holography: a review

Abstract. Computer-generated holography (CGH) is a technique to generate holographic interference patterns. One of the major issues related to computer hologram generation is the massive computational power required. Hardware accelerators are used to accelerate this process. Previous publications targeting hardware platforms lack performance comparisons between different architectures and do not provide enough information for the evaluation of the suitability of recent hardware platforms for CGH algorithms. We aim to address these limitations and present a comprehensive review of CGH-related hardware implementations.
The Perception of Head Teachers on the Instructional Performance of Teachers by Distance Learning in the Upper West Region of Ghana

The goal of the study is to analyze the perception of head teachers on the instructional performance of teachers by distance learning in the Upper West Region of Ghana. We cannot continue to pretend distance education does not matter, to the development of education in Ghana. Researching into distance learning in the present times is crucial because the rate at which distance learning is expanding needs attention. Common observation has shown that you can sight at least one distance learning student in most organizations. The situation has become critical, and we need to investigate more into the new area that has revolutionalized the educational system in Ghana. The researcher is interested in the question whether teachers after receiving instructional training in distance learning are performing well in the classroom. The design of the study is a case study, and the site is the Upper West Region of Ghana. Purposive and snowballing methods are used to select the sample. A survey questionnaire is used to gather data for the study, and analysis was primarily descriptive. The study is important because research has shown that, distance learning programs are valid and relevant, but some people also believe they are not reliable and trustworthy. We need to continue to investigate the issues of distance learning programs. It should be a matter of great concern to all stakeholders in education, on what can or cannot be done, to make the Ghana Education Service accept or reject teachers by distance learning.
Use of Tissue Doppler Imaging in horses – exercise stress echocardiography with Tissue Doppler Imaging in healthy horses and horses with cardiac disease

The evaluation of performance capacity with exercise test is of particular importance in horses with mild to moderate valvular regurgitations as a possible exercise intolerance, and a detrimental cardiac function is often first detected after exercise. Aim of the study was the comparison of myocardial velocities evaluated with Tissue Doppler imaging in healthy horses and horses with a cardiologic disease. 20 adult warmblood horses without cardiovascular diseases and 40 horses with valvular regurgitation or atrial fibrillation were examined. The examination included a clinical examination and standard electroand echocardiographic examinations at rest. Additionally, the left ventricular septum (IVS) and the left ventricular free wall (LVW) were evaluated with tissue Doppler imaging at rest and after lung exercise. The peak systolic (S), early diastolic (E-Wave) and late diastolic (A-Wave) myocardial velocities were analysed with colour-coded Tissue Doppler and imaging (TVI) and with PW-Tissue Doppler Imaging respectively. Horses with atrial fibrillation (n=15) showed an increase of systolic myocardial velocities at rest (TVI: IVS: control: -3.92±1.54cm/s, AF: -6.66±3.26cm/s, p<0.0001, LVW: control: 7.14±1.18cm/s, AF: 10.03±3.10cm/s, p<0.0001) and after exercise (PW: IVS: control: -13.37±3.84cm/s, AF: -17.15±3.93cm/s, p<0.005, LVW: control: 13.53±3.66cm/s, AF: 17.95±3.50cm/s, p<0.001) compared to the healthy control horses. Furthermore, the group of horses with atrial fibrillation had higher early diastolic myocardial velocities then the control horses (TVI: IVS: control: 12.34±2.91cm/s, AF: 16.70±6.13cm/s, p<0.001, LVW: control: -17.32±5.25cm/s, AF: -22.25±5.19cm/s, p<0.01). Horses with mitral valve regurgitation (n=15) also had higher systolic myocardial velocities, but only at rest compared to the healthy control horses (PW: IVS: control: -8.36±1.78cm/s, MVI: -10.99±3.13cm/s, p<0.005), while horses with aortic valve regurgitations (n=10) had higher early diastolic myocardial velocities at rest (PW: IVS: control: 17.06±3.85cm/s, AVI: 20.30±3.59cm/s, p<0.05), but higher late diastolic velocities after exercise compared to the healthy control horses (TVI: LVW: control: -8.62±3,7cm/s, AVI: -11.86±2.05cm/s, p<0.05). The myocardial analysis with Tissue Doppler imaging was feasible at rest and after exercise. The increase of myocardial velocities in the horses with cardiovascular disease is probably the result of an increase in contractility due to increased filling pressure of the ventricle in the presence of adequate ventricular capacity.
