A particle image velocimetry study of dual-rotor counter-rotating wind turbine near wake
Authors: Hollands Eloise O. , He Chuangxin , Gan Lian 
Published: March 2020

AbstractThis experimental work studied the flow characteristics in the near wake region behind dual-rotor wind turbines using two-dimensional particle image velocimetry. Two auxiliary rotors of 50% and 80% scale of the main rotor were installed upwind and operated in counter-rotating condition, which are compared to the conventional single-rotor turbine. In all the three configurations, a constant Reynolds number$$9.5\times 10^4$$9.5×104was applied, and all the rotors operated at a fixed tip speed ratio of 3.46. The mean and phase-averaged velocity fields were investigated together with the turbulence kinetic energy. It was found that the two auxiliary rotors do not result in a significantly different wake flow property. The configuration implementing the$$50\%$$50%auxiliary rotor sees a slightly better wake characteristics, in terms of weaker main rotor tip vortices and a counter-rotating swirling shear region at the mid-span behind the main rotor. The decay rates of the peak vorticity of the main rotor tip vortices and their circulation are found to follow an exponential manner.Graphic abstract

Published: March 2020

Abstract

Introduction
Cavernositis is a rare acute infection of the corporal bodies of the penis. It might result in corporal cavernosal abscesses, fibrosis, and subsequently erectile dysfunction if the treatment is inadequate. Previous reports advocate penile aspiration when cavernosal abscesses were significantly present.

Aim
We report 2 cases of cavernositis treated by the standard antimicrobial therapy in addition to the daily use of phosphodiesterase type 5 inhibitors (iPDE-5).

Methods
We include 2 patients who fulfill the criteria for the diagnosis of cavernositis. They were diagnosed clinically based on history and physical examination. Patient 1 had multifocal abscesses on initial penile contrast-enhanced magnetic resonance imaging (MRI). This patient showed rapid clinical improvement with the addition of phosphodiesterase inhibitor (PDEi) to the antimicrobial therapy without the need for surgical drainage of the abscesses. Patient 2 had persistent infection despite 3 weeks of oral second-generation cephalosporin (Cefuroxime). But he showed significant clinical improvement after being started on PDEi in conjunction with the current antimicrobial therapy. Follow-up after 3 months by clinical examination and penile magnetic resonance imaging in both patients showed normal erectile function with no scarring.

Conclusion
PDEi have promising results on disease progression and outcomes. It synergizes the effect of antimicrobial therapy and can potentially reduce the residual corporal fibrosis and erectile dysfunction. However, large studies are required to validate and generalize this treatment approach.
Compersion: An Alternative to Jealousy?
Authors: BRUNNING LUKE 
Published: March 2020

AbstractCompersion is an important concept for non-monogamous people. Often described as jealousy's opposite, compersion labels positive feelings toward the intimacy of a beloved with other people. Since many people think jealousy is ordinary, intransigent, and even appropriate, compersion can seem psychologically and ethically dubious. I make the case for compersion, arguing it focuses on the flourishing of others and is thus not akin to pride, vicarious enjoyment, or masochistic pleasure. People cultivate compersion by softening their propensity to be jealous and by attending to the flourishing of others, which requires them to tackle entitlement and temper vulnerability. I argue that jealousy is not a valuable emotional disposition; its instrumental benefits are minor, unstable, and have to be traded against the harms of aggression. Arguments that conclude that jealousy is a virtue rest on contentious premises and overlook the practical question as to whether jealousy and compersion could be cultivated together.
Cerebrospinal Fluid Flow Cytometry: Utility in Central Nervous System Lymphoma Diagnosis
Authors: Au Ka Loong Kelvin , Latonas Sarah , Shameli Afshin , Auer Iwona , Hahn Christopher 
Published: March 2020

ABSTRACT:Background:Flow cytometry of the cerebrospinal fluid (CSF) is used in isolation or as an adjunct to cytology to increase the sensitivity of detecting central nervous system (CNS) lymphoma. We aimed to evaluate the sensitivity of CSF flow cytometry as a diagnostic screening tool for primary CNS lymphoma in patients presenting with undifferentiated neurologic symptoms.Methods:We retrospectively reviewed all CSF samples received by the Calgary Laboratory Services Flow Cytometry Laboratory from 2012 to 2015. Clinical data, laboratory investigations, radiologic imaging studies, and pathological data were analyzed. Clinical review extended to 2 years post-CSF flow cytometric testing.Results:Only 43/763 (5.6%) samples of CSF flow cytometry in 28/573 (4.9%) patients were found to be positive for a hematological malignancy in patients with undifferentiated neurologic symptoms. The overall sensitivity of the test was 13.8% with 25 patients with negative CSF flow cytometry later having a positive biopsy for CNS lymphoma. CSF flow cytometry was negative in all cases when at the time of CSF examination the patient did not have a previous hematological malignancy or findings of abnormal enhancement on MRI (n = 249).Conclusion:CSF flow cytometry has low utility in screening for primary CNS lymphoma in the absence of a previous history of hematologic malignancy or findings of abnormal enhancement on MRI.

Published: March 2020

AbstractOrnamental jewelweed (Impatiens glanduliferaRoyle) is an alien invasive plant in Europe. This annual plant often grows in riparian habitats where herbicides are prohibited. Several studies have reported the negative effect on ecosystem and ecosystem services by this species. However, limited research is published on control measures and the aim of our study was to explore use of hot water and cutting to controlI. glandulifera. A lab experiment showed that the lethal water temperature for seed was between 45 and 50 C. In a pot experiment with seeds in soil, emergence ofI. glanduliferawas reduced by 78% and 93% compared with the untreated control with volumes of hot water (80 C) of 7.2 and 14.5 L m−2, respectively. When treatments were conducted on relatively tall plants (almost 60 cm) in late June, hot water gave significantly better control than cutting. Compared with an untreated control,I. glanduliferacover was reduced by 97% and 79% after hot water and cutting, respectively. Application of hot water to smaller (<40 cm) and less developed plants (BBCH 12–13) in early June and cutting of plants with visible flower buds (mid-July) led to no significant difference in cover. Compared with an untreated control,I. glanduliferacover was reduced by 99% (cut below first node) and 91% (hot water and cut above first node). When relatively tall plants (almost 60 cm) were treated, hot water use was high (31.1 L m−2) and required twice as many work hours (4.8 min m−2) as cutting (2.4 min m−2). When smaller plants (<40 cm) were targeted, work hours and hot water use were reduced to 2.1 min m−2and 13.7 L m−2, respectively.
New Early Devonian (late Emsian) placoderms from Belarus
Authors: Plax Dmitry P. , Newman Michael J. 
Published: March 2020

AbstractFour placoderm fishes are described from the Lepel Beds of the Vitebsk Regional Stage of the Lower Devonian (upper Emsian) of Belarus. Two forms are new (Stipatosteus svidunovitchi new genus, new species and Actinolepis zaikai new species) and the other two taxa are left in open nomenclature (Coccosteidae gen. indet. sp. indet.; Placodermi indet. 1). Specimens of all four forms consist of disarticulated, mostly well-preserved plates (some are worn at the edges) originating from the cores of six boreholes. Additionally, the paper presents data on organic remains with the placoderms. A detailed lithological description of the enclosing rocks and a taphonomic description of the ichthyofauna are also provided. The 2010 Stratigraphic Chart of the Devonian deposits of Belarus was used as the stratigraphic basis. The presence of the genus Actinolepis Agassiz, 1844 in these deposits as well as in the Emsian of the Baltic region and Spitsbergen suggests a regional paleogeographic connection at this time.UUID: http://zoobank.org/368b44df-e9e9-417c-a0e0-f7e138b7f4ec
HIDDEN DEBATES OVER THE STATUS OF THE CASAMANCE DURING THE DECOLONIZATION PROCESS IN SENEGAL: REGIONALISM, TERRITORIALISM, AND FEDERALISM AT A CROSSROADS, 1946–62
Authors: AWENENGO DALBERTO SÉVERINE 
Published: March 2020

AbstractThe article studies the contexts in which the idea of a separation of the Casamance from the rest of Senegal arose during the process of decolonization. The idea was an outgrowth of colonial representations forged since the end of the nineteenth century. It was first formulated by the French authorities in secret discussions with the representatives of the Casamance in the context of the 1958 referendum. It was taken over by local political leaders who saw it as a possible answer to the debates over representation that arose in the post-war process of democratization, and later by proponents of political mobilization at the sub-regional level after independence. By examining this little-known moment of possibility, the article shows that the claims of the current armed independence movement are in fact part of a longer, more ambivalent history in which a separatist imaginary of the Casamance took shape.
THE NORTHEASTERN FACTOR IN SOUTH AFRICAN HISTORY: REEVALUATING THE VOLUME OF THE SLAVE TRADE OUT OF DELAGOA BAY AND ITS IMPACT ON ITS HINTERLAND IN THE EARLY NINETEENTH CENTURY
Authors: CHEWINS LINELL , DELIUS PETER 
Published: March 2020

AbstractThis article, largely on the basis of in-depth research in archives in Lisbon, provides an account of the trading systems linking Delagoa Bay to its southern hinterland. Within this framework we argue that the role of the slave trade has been previously underestimated. There is evidence that the booming demand for slaves in Brazil and on the Mascarene Islands hit this region with force. The scale of that trade is difficult to establish because it was, by and large, illicit and so not systematically recorded. There are indications of a significant trade prior to 1823 and a substantial one after that date. There is also evidence that northern Nguni groups, including the Zulu kingdom, were deeply involved in this trading system. The main sources of captives, however, were militarily weak societies, like the Tembe, which lived closer to the Bay.
Effekt: Capability-passing style for type- and effect-safe, extensible effect handlers in Scala
Authors: BRACHTHÄUSER JONATHAN IMMANUEL , SCHUSTER PHILIPP , OSTERMANN KLAUS 
Published: March 2020

AbstractEffect handlers are a promising way to structure effectful programs in a modular way. We present the Scala libraryEffekt, which is centered around capability passing and implemented in terms of a monad for multi-prompt delimited continuations.Effektis the first library implementation of effect handlers that supports effect safety and effect polymorphism without resorting to type-level programming. We describe a novel way of achieving effect safety using intersection types and path-dependent types. The effect system of our library design fits well into the programming paradigm of capability passing and is inspired by the effect system of Zhang & Myers (2019,Proc. ACM Program. Lang.3(POPL), 5:1-5:29). Capabilities carry an abstract type member, which represents an individual effect type and reflects the use of the capability on the type level. We represent effect rows as the contravariant intersection of effect types. Handlers introduce capabilities and remove components of the intersection type. Reusing the existing type system of Scala, we get effect subtyping and effect polymorphism for free.

AbstractWe explore the design and implementation of Frank, a strict functional programming language with a bidirectional effect type system designed from the ground up around a novel variant of Plotkin and Pretnar’s effect handler abstraction. Effect handlers provide an abstraction for modular effectful programming: a handler acts as an interpreter for a collection of commands whose interfaces are statically tracked by the type system. However, Frank eliminates the need for an additional effect handling construct by generalising the basic mechanism of functional abstraction itself. A function is but the special case of a Frankoperatorthat interprets no commands. Moreover, Frank’s operators can bemultihandlerswhich simultaneously interpret commands from several sources at once, without disturbing the direct style of functional programming with values. Effect typing in Frank employs a novel form of effect polymorphism which avoids mentioning effect variables in source code. This is achieved by propagating anambient abilityinwards, rather than accumulating unions of potential effects outwards. With the ambient ability describing the effects that are available at a certain point in the code, it can become necessary to reconfigure access to the ambient ability. A primary goal is to be able to encapsulate internal effects, eliminating a phenomenon we calleffect pollution. Moreover, it is sometimes desirable to rewire the effect flow between effectful library components. We propose adaptors as a means for supporting both effect encapsulation and more general rewiring. Programming with effects and handlers is in its infancy. We contribute an exploration of future possibilities, particularly in combination with other forms of rich type systems.

AbstractObjectives:To characterise the mortality and neurological outcomes of paediatric cardiac patients requiring cardiopulmonary resuscitation for more than 30 minutes prior to extracorporeal membrane oxygenation cannulation and to identify risk factors associated with adverse outcomes in this population.Materials and methods:Observational retrospective cohort study in paediatric cardiac patients undergoing cardiopulmonary resuscitation for greater than 30 minutes prior to cannulation in a tertiary children’s hospital, from July 2000 to July 2013.Results:Seventy-three paediatric cardiac patients requiring cardiopulmonary resuscitation for more than 30 minutes prior to cannulation were included in the study. Survival to hospital discharge was 43.8%, with 75% of survivors having either normal neurologic function or only mild disability. Multivariable logistic regression analysis demonstrated that increased use of calcium during resuscitation (odds ratio 14.5, p 0.01), cardiopulmonary resuscitation duration >50 minutes (odds ratio 4.12, p 0.03), >6 interruptions of chest compressions during cannulation (odds ratio 6.40, p 0.03), the need for continuous renal replacement therapy (odds ratio 11.1, p 0.001), and abnormal pupillary response during extracorporeal membrane oxygenation (odds ratio 33.9, p 0.006) were independent predictors for hospital mortality.Conclusion:Survival after cardiopulmonary resuscitation for more than 30 minutes prior to extracorporeal membrane oxygenation cannulation in our paediatric cardiac cohort was 43.8%. Factors associated with mortality included calcium use during resuscitation, longer cardiopulmonary resuscitation, increased chest compression pauses during cannulation, the use of continuous renal replacement therapy, and abnormal pupils during extracorporeal membrane oxygenation support. A prospective assessment of these factors in paediatric cardiac patients may be beneficial in improving outcomes.

AbstractOnline learning has become an increasingly expected and popular component for education of the modern-day adult learner, including the medical provider. In light of the recent coronavirus pandemic, there has never been more urgency to establish opportunities for supplemental online learning. Heart University aims to be “the go-to online resource” for e-learning in CHD and paediatric-acquired heart disease. It is a carefully curated open access library of paedagogical material for all providers of care to children and adults with CHD or children with acquired heart disease, whether a trainee or a practising provider. In this manuscript, we review the aims, development, current offerings and standing, and future goals of Heart University.
An Impact Crater Origin for the InSight Landing Site at Homestead Hollow, Mars: Implications for Near Surface Stratigraphy, Surface Processes, and Erosion Rates

AbstractThe InSight mission to Mars landed within Homestead hollow on an Early Amazonian lava plain. The hollow is a 27‐m‐diameter, 0.3‐m‐deep quasi‐circular depression that shares morphologic and sedimentologic characteristics to degraded impact craters. Unlike the intercrater plains outside of the hollow, the interior lacks cobbles and is dominated by loose sand, granules, and pebbles. Fresher craters near the landing site exhibit meter‐scale bedforms in their ejecta and on their floors due to sediment trapping. The sedimentology of the interior fill of Homestead hollow suggests similar trapping. The hollow falls along a morphologic continuum that requires low rates of rim degradation and fill. Crater degradation rates (rim erosion plus filling) in the landing site decline nonlinearly through time from 10−2 to 10−4 m/Myr as craters evolve to a hollow‐like form. Rim erosion rates are lower initially, at 10−3 m/Myr, but converge with degradation rates to 10−4 m/Myr. This implies that while filling plays an important role soon after crater formation, it is limited in later stages. Crater statistics indicate that the bulk of the fill occurred in the first ~50 Myr for Homestead hollow. The estimated maximum age of the hollow is ~400 to 700 Myr. This requires near‐zero fill aggradation and long‐term soil stability for the bulk of the crater's history. Fill stability manifests in Homestead hollow as a ~5‐ to 10‐cm‐thick duricrust, formed by exchanges of atmospheric water vapor with soil. The estimated degradation in the hollow requires ~2 to 3 m of sedimentary fill beneath the lander.

AbstractPlant architecture includes vital traits that influence and benefit crops, and economically important trees. Different plant architectures provide natural beauty. Weeping ornamental plants are aesthetically appealing to people. The regulatory mechanism controlling the weeping trait is poorly understood in crape myrtle. To investigate the weeping trait mechanism, transcriptional profiling of different organs in weeping and upright crape myrtle was performed based on phenotype. Phenotypic and histological analyses demonstrated that endodermal cells were absent, and that new shoot phenotypes could be rescued by the GA3 treatment of weeping plants. The transcriptional analysis and coexpression network analysis (WGCNA) of differentially expressed genes indicated that GA synthesis and signal transduction pathways play a role in weeping traits. When the expression level of a negative element of GA signaling, LfiGRAS1, was reduced by virus-induced gene silencing (VIGS), new branches grew in infected plants in a negatively geotropic manner. An integrated analysis implied that GA had a strong influence on weeping crape myrtle by interacting with other factors. This study helps to elucidate the mechanism governing the weeping trait and can improve the efficiency of breeding in Lagerstroemia.

AbstractIntradialytic cycling is a widely used workout mode, whereas added benefit of other exercise modalities remains unknown. This is the first randomised controlled trial on the effects and sustainability of functional training and counselling in addition to intradialytic cycling. Patients were randomly assigned to a kinesiologist-guided functional training in addition to intradialytic cycling (n = 20, experimental group) or intradialytic cycling only (n = 20, control group) over 16 weeks. The experimental group attended predialysis functional exercise in the first eight weeks and afterward performed functional training at home for the next eight weeks. The primary study endpoint was 10-repetition-sit-to-stand test time at eight weeks: at this test, the experimental group improved significantly better than controls (−4.5 ± 1.9 s, 95%CI −8.4 to −0.7; P = 0.021), which was maintained at week 16 (−4.7 ± 2.1 s, 95%CI −9.0 to −0.3; P = 0.037). At week 8, the experimental group significantly outperformed controls also at handgrip strength (P = 0.004), lower body flexibility test (P < 0.001), balance test (P < 0.001), and upper body flexibility test (P = 0.003). At week 16, superior results of the experimental group in secondary end-points remained preserved for handgrip strength, balance, and upper body flexibility tests. Functional training with exercise counselling meaningfully improves physical performance and successfully prepares patients for sustainable home exercise.

Published: March 2020

AbstractAmbipolar carbon nanotube based field-effect transistors (AP-CNFETs) exhibit unique electrical characteristics, such as tri-state operation and bi-directionality, enabling systems with complex and reconfigurable computing. In this paper, AP-CNFETs are used to design a mixed-signal machine learning logistic regression classifier. The classifier is designed in SPICE with feature size of 15 nm and operates at 250 MHz. The system is demonstrated in SPICE based on MNIST digit dataset, yielding 90% accuracy and no accuracy degradation as compared with the classification of this dataset in Python. The system also exhibits lower power consumption and smaller physical size as compared with the state-of-the-art CMOS and memristor based mixed-signal classifiers.
