Dilemmasituation: Nächtlicher Unruhezustand beim älteren Patienten
Authors: Schwerthöffer Dirk , Fatke Bastian , Förstl Hans
Published: April 2020

Elderly individuals, particularly those with cognitive impairment, are oftentimes restless during the night, and this increases the distress of relatives, professional carers and themselves. A number of conditions other than dementia need to be considered from nyctophobia and insomnophobia, to pain, specific motor disorders during sleep, parasomnias as REM-sleep behaviour disorder, dipping, hypoglycemia, withdrawal or excessive tea, coffee and alcohol consumption. A clear-cut differential diagnosis between dementia and delirium is not always possible, as dementia is the major risk factor for confusional states decreasing the vulnerability by anticholinergic medication and any other disruptive factor, biological or psychological. Treatment of nocturnal agitation usually requires (1) reassurance and re-orientation; (2a) the discontinuation of anticholinergic substances; (2b) symptomatic psychotropic intervention; and (3) causal treatment of underlying problems. Benzodiazepines should only be used at the lowest necessary dosage for the shortest possible time, particularly in individuals who are already benzodiazepine-dependent. Quetiapine or mirtazapine at low dosages can be employed in patients with psychotic or depressive symptoms. Melatonin and its derivatives hold promise for chronic circadian rhythm disorders. There is no “one fits all” recipe for this notorious problem and each case needs to be examined individually.
Synthesis and Structure Activity Relationships of Chalcone based
Benzocycloalkanone Derivatives as Adenosine A1 and/or
A2A Receptor Antagonists
Authors: Janse van Rensburg Helena D. , Legoabe Lesetja J. , Terre’Blanche Gisella
Published: April 2020

Adenosine A1 and/or A2A receptor antagonists hold
promise for the potential treatment of neurological conditions, such as
Parkinson’s disease. Herein, a total of seventeen benzocycloalkanone
derivatives were synthesised and evaluated for affinity towards adenosine
receptors (A1 and A2A AR). The obtained results allowed
for the conclusion that affinity and/or selectivity of the
2-benzylidene-1-indanone and -tetralone derivatives toward A1
and/or A2A ARs may be modulated by the nature of the
substituents (either -OH, -OCH3 or morpholine) attached at position
C4 of the 1-indanone core and C5 of the 1-tetralone core as well as the
meta (C3’) and/or para (C4’)
position(s) on ring B. Several compounds (2a–b,
3b–c and 4a–b) possessed
affinity for the A1 and/or A2A AR below 10
µM. Additionally, compounds 2a, 3b and 4a were
A1 AR antagonists. These results, once again, confirmed the
importance of C4 methoxy-group substitution on ring A in combination with
meta (C3’) and/or para (C4’)
hydroxyl-group substitution ring B of the 2-benzylidene-1-indanone scaffold
leading to drug-like compounds 1h and 1j with affinity in the
nanomolar-range.

Authors: Gudziol Hilmar , Quaas Tina , Guntinas-Lichius Orlando , Lehnich Holger , Bitter Thomas
Published: April 2020

Hintergrund Im aufmerksamen Wachzustand verlängern angenehme Gerüche häufig die Einatmung, während unangenehme Gerüche häufig die Ausatmung verkürzen. Es soll überprüft werden, ob dieses induzierte Atemmuster auch im Schlaf erhalten bleibt.

Methodik 23 gesunde normosmische Erwachsene wurden für 1 Nacht polysomnografisch untersucht und dabei entweder mit H2S, Phenylethylalkohol (PEA) oder CO2 über ein Fluss-Olfaktometer randomisiert impulsartig gereizt. Anhand der standardmäßig erfassten Polysomnografie-Kurven erfolgte die Bestimmung der Schlafstadien (REM, NREM, pWach), der Dauer der Inspiration (DIN) und der Dauer der Exspiration (DEX). DIN und DEX wurden von 6 prästimulatorischen Atemzügen und vom Reizatemzug (RAZ) bestimmt. Daraus wurde der Reaktionsindex (RI) berechnet, der angibt, ob eine bedeutsame Änderung von DIN und/oder DEX vorliegt. Die verschiedenen RI wurden um die spontanen RI korrigiert und entsprechend der Reizart und den Schlafstadien analysiert.

Ergebnis Reaktionsindizes mit Verkürzungen von DEX waren bei einer H2S-Reizung größer als spontane RI und RI bei einer PEA-Reizung. Bei einer CO2-Reizung waren RI mit Verkürzungen von DIN und DEX größer als bei olfaktorischer Reizung. Alle RI waren in ihrer Ausprägung zwischen den Schlafstadien gleich. Im REM war der Unterschied der olfaktorischen RI mit verkürzten DEX zwischen einer H2S- und PEA-Reizung am größten.

Schlussfolgerung Bei Reizung mit einem unangenehmen Geruch im Schlaf bleibt das respiratorische Reaktionsmuster aus dem Wachzustand erhalten. RI mit verkürzten DEX können als unvollkommene Arousals angesehen werden.

Authors: Morani Ajaykumar C. , Taher Ahmed , Ramani Nisha S. , Jensen Corey T. , Patel Asif , Mujtaba Bilal
Published: April 2020

Pancreatic cancer is rare but is one of the deadliest cancers. Complete surgical removal of the cancer with negative margins is the only potentially curative treatment. However, majority of the cases present with distant metastases and/or locally advanced disease, and only a limited subset (up to 20%) of patients are surgical candidates. Therefore, accurate staging of pancreatic cancer is very important for treatment planning. It is very important to distinguish between patients who are surgical candidates and those who would need palliative treatment. Imaging plays a crucial role in the detection of the primary tumor, vascular involvement and variants, metastasis, prediction of resectability, and monitoring treatment response. High-resolution multidetector computed tomography (CT) is the primary imaging modality of choice for diagnosing and staging pancreatic cancers. Nevertheless, integration of ultrasound, CT, and magnetic resonance imaging (MRI) may be needed for accurate determination of the tumor extent and optimal management. Herein, we aim to provide a radiological review for “what the surgeon wants to know about pancreatic cancer?” In this review, we highlight the main types of invasive pancreatic cancers and discuss the role of imaging in determining the resectability of pancreatic tumors and the role of neoadjuvant treatment in downstaging borderline or unresectable cases in addition to featuring significant postsurgical complications.

Authors: Shojaee-Mend Hassan , Ayatollahi Haleh , Abdolahadi Azam
Published: April 2020

Background Development of ontologies in traditional medicine can be a foundation for other applications of informatics in this field. Despite the importance of the development of ontologies in traditional medicine, there are few review studies in this area. This study aims to review different methods for ontology development and evaluation in traditional medicine.

Methods This review study was performed in 2019. To find related papers, six databases including Scopus, Web of Science, PubMed, Embase, IEEE Xplore, and SpringerLink were searched. Initially, 761 articles were identified. After applying inclusion and exclusion criteria, 22 articles were selected to review different methods for ontology development and evaluation in traditional medicine.

Results Five different methods were used for ontology development in traditional medicine, namely conventional, customized, semiautomatic, upper-level, and large-scale methods. The results showed that ontology evaluation was only considered in 32% of the studies. The common methods used for ontology evaluation were competency questions, expert-based evaluation, and automatic detection of inconsistency errors.

Conclusion Development of ontologies is of high importance for organizing knowledge in traditional medicine, as this branch of medicine is often not documented or is documented in local languages. The results of this study can help ontology developers to be familiar with the common methods of ontology development and evaluation in traditional medicine and use them for future research.

Authors: K. Remya , Kumar Arunachalam , Kumar Vishal
Published: April 2020

Uncus or uncinate process is flange-like lip which arises from most of the lateral circumference of the upper margin of the vertebral body. It ossifies from neural arch of vertebrae. These are commonly found in lower five cervical vertebrae. The area between the periphery of intervertebral disc and uncus is occupied by loose fibrous tissue. When this fibrous tissue resorbs it leaves a space that constitutes Luschka's joint. These joints are well developed and larger in the mid to lower cervical region and smaller joints appear in the most cranial and caudal levels. We have found total of 23 such type of articular facets, on both upper and lower surfaces. These joints are clinically important because of its relationship with vessels and nerves. Many of the neurological symptoms of the arm, neck and back of the head are related to these accomadative joints

THE POLLEX – INDEX COMPLEX AND THE KINETICS OF OPPOSITION
Authors: Kumar Arunachalam
Published: April 2020

The term opposition is exclusive to human manual articulation. The origin and development of the opposable thumb was a milestone in evolutionary history of man. The transition from pongid, pithecoid to paranathropus and thereon to anthropoid apes was witness to the transformation of the apposable thumb to an opposable one. While a few marsupials, primates and prosimians can and do 'oppose' their digits (either of the forelimb or hind-limb) these articulations are non-classical and cannot be categorized as opposition. The shortness of the thumb in proportion to the size and length of the palm / foot handicaps performance of functionally efficient 'opposition' in most species (1).

According to evolutionary biologists, one of the more singular factors elevating man as a higher mammal, as compared to any other, is the modification in the functional capability of the thumb. The human thumb stands alone in its talent to 'oppose'. Anatomically, 'opposition' implies the movement by which you can touch the tip of your thumb to the tips of other fingers of the same hand. No animal except the human kind has a truly opposable thumb(2)

The biomechanics of opposition of the pollex with special reference to its preferred digit, the index is discussed in this paper, in the light of increasing stress and usage of these digits in modern man exposed to newer personal communication devices and technologies which demand dexterity and speed in manipulation of these specific joints for specialized functions

Published: April 2020

Blindness is one of the most significant social problems in India with uncorrected refractive errors as the second major cause accounting for 19.7% of blindness and low vision.

All adolescents (12-18 years) attending the eye clinic from Jan 2007-Jan 2009 for any eye ailment were examined and screened for refractive error using Snellen's chart.

Out of total 930 adolescents, 508(54.62%) of adolescents had refractive errors. Of the total males and females examined 57.43% and 52.12% respectively had refractive errors. The mean age of presentation was 14.3 years. Most of the adolescents presented with myopia 257(50.59%) followed by astigmatism (35.23%) and hypermetropia (14.17%).

High prevalence of refractive errors warrants early detection and treatment.
HOPPING IN BIRDS: IS THE CHOICE OF GAIT INFLUENCED BY CERVICAL MOBILITY AND FIELD OF VISION?
Authors: Kumar Arunachalam
Published: April 2020

One of the more intriguing questions in avian locomotion is why some birds, when on ground, choose to hop while others prefer walking. Biped gait is common to birds as well as the most evolved among mammals, man. Observations made show that, choice of gait in birds is determined by a remote factor–the range and extent of neck mobility. The wider the gamut of cervical mobility, the wider is the 'field of vision' available. Cervical movement capability is perhaps the single most deterministic factor in the bird's choice of terrestrial gait.

Published: April 2020

Congenital coronary artery anomalies are extremely rare causes of early cardiac failure. Several cardiac lesions are associated with coronary anomalies such as pulmonary atresia with intact ventricular septum. Isolated coronary ostial atresia is extremely rare and described in only a few published case reports. To our knowledge, there were two reports of bilateral coronary ostial atresia in which the entire coronary arterial system originated from the right ventricle without other intracardiac defects. We present a case of a full-term infant who presented with severely depressed biventricular function secondary to bilateral coronary ostial atresia.

Impact of an air-in-liquid compound drop onto a liquid surface
Authors: Zhu Siqi , Kherbeche Abderrahmane , Feng Yumeng , Thoraval Marie-Jean
Published: April 2020

We study experimentally the dynamics of a liquid drop containing an air bubble falling onto a pool of the same liquid. We first develop a drop-on-demand setup capable of forming repeatable compound drops without any surfactant. Then, we investigate the impact dynamics above and below the pool surface combining two high-speed cameras. We identify three different regimes as the impact height increases. At low impact velocities, the bubble is engulfed into the pool. Above a critical impact velocity, the bubble bursts during impact. For higher falling heights, the bubble ruptures before reaching the pool due to air drag decelerating the compound drop.
Effective hardness of interaction from thermodynamics and viscosity in dilute gases
Authors: Bell Ian H.
Published: April 2020

The hardness of the effective inverse power law (IPL) potential, which can be obtained from thermodynamics or collision integrals, can be used to demonstrate similarities between thermodynamic and transport properties. This link is investigated for systems of increasing complexity (i.e., the EXP, square-well, Lennard-Jones, and Stockmayer potentials; ab initio results for small molecules; and rigid linear chains of Lennard-Jones sites). These results show that while the two approaches do not yield precisely the same values of effective IPL exponent, their qualitative behavior is intriguingly similar, offering a new way of understanding the effective interactions between molecules, especially at high temperatures. In both approaches, the effective hardness is obtained from a double-logarithmic temperature derivative of an effective area.

Published: April 2020

The eastern barn owl (Tyto delicatula) is a significant native predator of small mammals in Australia. Regurgitated pellets can provide important data on species presence, current or historical changes in mammal fauna over time, or data on cryptic or threatened species. We collected 125 pellets from Cravens Peak reserve, Simpson Desert, Queensland, and examined the contents, including changes in diet over time (using age of pellet as a proxy) and the relative importance of different prey. In total, 642 unique prey items were recorded, 92% of which were mammals. Small rodents were the dominant prey – Mus musculus and Pseudomys hermannsburgensis, and the presence of Notomys cf. fuscus, Pseudantechinus cf. mimulus and Dasycercus blythi were all significant, being range extensions. Such data add to more traditional or novel techniques to record community changes over time.
Interspecific variations in tree allometry and functional traits in subtropical plantations in southern China
Authors: Zhu Liwei , Hu Yanting , Zhao Ping
Published: April 2020

Mechanical stability against buckling and water transport resistance through xylem vary with increasing tree height. To explore interspecific allometry based on morphological and physiological traits can play a crucial role in revealing their ecological adaptation. Four architectural traits (tree height, diameter at the breast height (DBH), crown width and crown depth) and seven functional traits (specific leaf area (SLA), leaf total carbon concentration (TC), midday leaf water potential, leaf δ13C and δ18O, wood density and xylem water transport efficiency) were measured in Schima superba, Acacia auriculiformis and Eucalyptus citriodora plantations in the subtropical region of China. The mechanical stability declined in the order of S. superba > A. auriculiformis > E. citriodora. Taller species at a given DBH had slender stems and narrower crowns. Smaller leaf δ18O and more efficient xylem water transport were observed in two taller tree species, A. auriculiformis and E. citriodora. Smaller SLA, higher leaf TC and larger leaf area indicated more carbon allocation to leaves of S. superba. The variations in architectural and functional traits with tree allometry among tree species may provide a more complete understanding of species-specific growth strategies in this subtropical region.

Arc
attenuates the behavioral and molecular responses for sleep homeostasis in mice
Authors: Suzuki Ayako , Yanagisawa Masashi , Greene Robert W.
Published: April 2020

Significance

Arc
is a neural immediate early gene involved in synaptic downscaling and is robustly induced by prolonged wakefulness in rodent brains. However, it remains unclear if and how
Arc
is involved in sleep regulation. Here we find that
Arc
is important for inducing multiple homeostatic responses induced by sleep deprivation at behavioral and molecular levels: (1) rebound of sleep time; (2) expression of a subset of sleep deprivation-induced genes; and (3) synaptic glutamate receptor expression. In sleep-deprived wild-type brains, Arc protein levels are significantly increased in the nucleus, cytoplasm, and synapse, suggesting multiple roles for Arc depending on its subcellular location. These findings provide the functional evidence for the role of
Arc
in homeostatic sleep regulation.
What Is a Replication?
Authors: Machery Edouard
Published: April 2020

This article develops a new, general account of replication (the Resampling Account of replication). I argue that a replication is an experiment that resamples the experimental components of an original experiment that are treated as random factors and that the function of replications is, narrowly, to assess the reliability of the replicated experiments. On this basis, I argue that the common notion of conceptual replication is confused and that the ongoing controversy about the relative value of direct and conceptual replications should be dissolved.
Annual modulation in direct dark matter searches
Authors: Froborg Francis , Duffy Alan R
Published: April 2020

The measurement of an annual modulation in the event rate of direct dark matter detection experiments is a powerful tool for dark matter discovery. Indeed, several experiments have already claimed such a discovery in the past decade. While most of them have later revoked their conclusions, and others have found potentially contradictory results, one still stands today. This paper explains the potential as well as the challenges of annual modulation measurements, and gives an overview on past, present and future direct detection experiments.
Spatiotemporal dynamics of cross-field ejection events in recombining detached plasma
Authors: Tanaka Hirohiko , Kajita Shin , Natsume Hiroki , Saeki Isaya , Ohno Noriyasu
Published: April 2020

Three-dimensional spatiotemporal dynamics of detached helium plasma parameters along time, radius, and magnetic field were revealed in the linear device NAGDIS-II. To measure plasma parameters before and after the radial plasma ejection that was enhanced around the volume-recombining region, the conditional averaging technique was applied. The radial ejection was found to correlate with low-frequency changes of plasma-column parameters, which seemed to suppress the axial movement of the recombining region. Moreover, an azimuthal charge separation inside the ejected structure was observed, similar to the typical edge transport phenomenon: blobby plasma transport. The neutral flow effect was suggested as a candidate of the driving force.
Interfacial current distribution between helium plasma jet and water solution

Published: April 2020

The plasma–liquid interaction holds great importance for a number of emerging applications such as plasma biomedicine, yet a main fundamental question remains about the nature of the physiochemical processes occurring at the plasma–liquid interface. In this paper, the interfacial current distribution between helium plasma jet and water solution was measured for the first time by means of the splitting electrode method, which was borrowed from the field of arc plasma. For a plasma plume in continuous mode, it was found that the mean absolute current distribution at the plasma–liquid interface typically had an annular shape. This shape could be affected by regulating the air doping from the surrounding atmosphere, the gas flow rate, the applied voltage and the conductivity of the water solution. However, only the air doping fraction and the water conductivity could fundamentally change the interfacial current distribution from the annular shape to the central maximum shape. It was deduced that a certain amount of ambient air doping (mainly N2 and O2) and a low conductivity (typically <300 μS cm−1) of the treated water were essential for the formation of the annular current distribution at the plasma–liquid interface.
Can two quantum Cheshire cats exchange grins?
Authors: Das Debmalya , Pati Arun Kumar
Published: April 2020

A common-sense perception of a physical system is that it is inseparable from its physical properties. The notion of quantum Cheshire cat challenges this, as far as quantum systems are concerned. It shows that a quantum system can be decoupled from its physical property under suitable pre and postselections. However, in the quantum Cheshire cat setup, the decoupling is not permanent. The photon, for example, and its circular polarization is separated and then recombined. In this paper, we present a thought experiment where we decouple two photons from their respective polarizations and then interchange them during recombination. Thus, our proposal shows that that the belongingness of a property for a physical system is very volatile in the quantum world. This raises the question of reality of an observable at a much deeper level.
Torque Distribution Strategy Based on Deep Learning for Parallel Hybrid Electric Vehicle
Authors: Fang Yao , Kong Huifang , Fan Lei
Published: April 2020

In order to improve the fuel economy of hybrid electric vehicle (HEV), an improved deep recurrent neural network-based energy management strategy model (IDRNN-EMS) is proposed to learn optimal torque distribution strategy for the single-axle parallel hybrid electric vehicle (HEV). Specifically, we formulate EMS as time series prediction problem to meet the requirement of deep recurrent neural network (DRNN). Then, skip connection structure is introduced into deep recurrent neural network to improve the training efficiency of our proposed model. We provide comprehensive simulation evidence showing that the improved model with skip connection is easier to optimize in public platform TensorFlow. Comparing with the DRNN-EMS model, our improved model with ship connection yields remarkable performance in terms of fuel economy and accuracy.
Problems Analysis on Preparation of Oil and Gas Drilling Rig Installation for Next Operations Readiness after HPHT (High Pressure High Temperature) Well Operation
Authors: Samuelson Andrew , Nirbito Wahyu
Published: April 2020

Oil and gas drilling is an activity designed to bring oil and gas resources into the surface of the earth using drilling rig. One of the characteristics of drilling wells is HPHT (High-Pressure High Temperature) condition, where this type of well can reach temperature of 150 °C and pressure of 15,000 psi. Due to these extreme conditions, the drilling rig installation often need to be serviced after it operates under HPHT condition before it can be operated again. The influences of HPHT wells conditions to the equipment component in the drilling operation systems are studied to find out the probable failures root cause that make the drilling rig break down and have significant Non-Productive Time (NPT) after operated on HPHT well. During this study, we found out that the root cause of the problem is failed to apply a detailed requirements in SOP and Operation Manual as a provision of drilling operation. The problems become more significant for the rig performance and its NPT thus affecting the overall drilling program and company revenue.

Published: April 2020

The effect of welding parameters on GTAW (gas tungsten arc welding) between low carbon steel and 3CR12 ferritic stainless steel with ER308L filler metal was investigated with regard to microstructure and mechanical properties. The welded metal presented good configuration. The microstructure of weldment was found to be of widmanstatten austenite, acicular ferrite and martensite. Martensite and Cr-rich carbide precipitated particles formed under certain conditions in weldment produced results of both better hardness values and tensile strength. The results indicated that influence of these welding parameters have significant effects on microstructure and mechanical properties in welded metal.
Kinetic Sculpture Design Using the Dynamic Cage

Published: April 2020

Kinetic sculptures are attractive for periodic dynamic deformation effects. Designing such a sculpture is not easy considering the holistic shape versus many part details. To provide an easier design process, we propose a top-down framework for kinetic sculpture design. The system converts several input sketch curves to a dynamic cage, which shows the deformation of the sculpture’s holistic shape in motion. The user can manipulate the sculpture’s shape by dragging on the cage at any moment in motion. After that, a group of skeletons is generated from the cage. The user can adjust their shapes for detailed unit model generation. Experimental results show that with our system, designers can concentrate on the shape and motion effects, significantly promoting the orientation and speed of design.

Detection of the psychophysical state of a person and identification of a person by various biometric data is becoming an increasingly popular and widespread every year. The systems also detect the state of alcohol or drug intoxication. Managers need an employee who has certain qualities: paying attention to small details, honest and stress-resistant. At the same time, employers are faced with the task of choosing one of several job applicants. Video analytical tracking systems, supplemented by Eye tracking system and special test objects register parameters by which you can judge the characteristics inherent in the applicants. Such systems will make it easier to find people who have the competencies expected by the employer. The article presents the first results of the research on the reaction of the human pupil in response to an irritant compared with a stressful situation.

Cells are very sensitive to their direct environment—they place high demands, for example, on ambient culture medium, adjacent cell types, and the properties of surrounding material parts. As a result, mechanical and physical material properties—such as surface roughness, swelling, electrostatic effects, etc—can all have a significant impact on cell behaviour. In addition, a material’s composition also impacts whether that material meets biocompatibility requirements and can thus be considered for potential use in biomedical applications. The entry of high-resolution 3D printing technology in biotechnology has opened the door to individually-designed experiment-adaptable devices of almost unlimited complexity that can be manufactured within just a few hours. 3D printing materials are frequently lacking in the characteristics that make them suitable for biomedical applications, however.

This study introduces a high-resolution polyacrylic 3D printing material as a potential alternative material for use in cultivation systems with indirect or direct contact to cells. Viability analyses, studies of apoptotic/necrotic cell death response, and surface studies all suggest that this material meets the requirements for (in vitro) biocompatibility, and has surface properties sufficient to permit uninhibited cell proliferation for cells in direct contact to the material. Moreover, the translucency of this material facilitates the type of optical monitoring required for performing experiments in a microfluidic environment, or for facilitating microscopic observations.

In accordance with the 2018 joint consensus document issued by the European Heart Rhythm Association (EHRA), European Society of Cardiology (ESC) Working Group on Thrombosis, European Association of Percutaneous Cardiovascular Interventions (EAPCI), and European Association of Acute Cardiac Care (ACCA), and endorsed by the Heart Rhythm Society (HRS), Asia-Pacific Heart Rhythm Society (APHRS), Latin America Heart Rhythm Society (LAHRS), and Cardiac Arrhythmia Society of Southern Africa (CASSA), as well as with other recent ESC Guidelines, the management of antithrombotic therapy of patients with atrial fibrillation undergoing percutaneous coronary intervention requires that multiple and interconnected issues, including, duration of initial triple antithrombotic therapy, selection of P2Y12 inhibitor, choice of oral anticoagulant to be combined with antiplatelet therapy, intensity of oral anticoagulation throughout combination therapy, and choice of oral anticoagulant for indefinite therapy, are addressed. To assist the responsible physician in clinical decision making, a series of practical questions are proposed and discussed in the chronological sequence they should likely be answered.
What Is Wrong with Investment Arbitration? Evidence from a Set of Behavioural Experiments
Authors: Marceddu Maria Laura , Ortolani Pietro
Published: April 2020

Investment arbitration has attracted growing criticism both in academia and in the general political debate. The system has been criticized by groups and stakeholders with very different agendas – from academics to anti-globalization activists, from alt-right groups to policy-makers. While sharing a common aversion to such dispute resolution mechanism, these groups do not generally take the same viewpoints, and the same type of criticism could originate from different political and theoretical underpinnings. The current efforts to reform investor-state dispute settlement, undertaken both by the European Union and by the United Nations Commission on International Trade Law, constitute to a large extent an attempt to respond to the aforementioned public criticism. However, in spite of the growing importance of the topic in the public debate, reform discussions have been predominantly, if not exclusively, focused on states and their roles in, and their expectations towards, investment arbitration. Public opinion, conversely, remains largely overlooked. To fill this gap, this research devises an experimental approach to understand the roots of public criticism(s) against investment arbitration. In so doing, it aims to generate a constructive, timely and accessible empirical analysis of the theoretical underpinnings of ISDS criticisms, providing an integrated guide to one of the most heated debates in international economic law today. The main purpose is to understand which are the points of friction (real or perceived) that trigger public criticism against investment arbitration and, in the light of this information, whether this dispute resolution mechanism should be maintained in its current form, partially reformed or rejected entirely. To this end, the article presents the results of the first-ever set of behavioural experiments concerning ISDS and public opinion.
Three Worlds of Vocational Education: Specialized and General Craftsmanship in France, Germany, and The Netherlands

One of the biggest challenges in the design of educational systems concerns how vocational education and training (VET) systems are best organized for the labour markets of tomorrow. Do we need more specialized craftsmen with practical and specific skills that tightly link to specific occupations, or do we need a shift towards broader craftsmen with more general skills? Using microdata from France, Germany, and The Netherlands, we show that there are different ways by which the VET sector establishes school-to-work linkages. Linkages between school to work are on average stronger in systems with a dual VET sector compared to a full school-based model. However, an important reason why linkages are stronger is because of compositional differences, as in dual VET systems more students tend to be enrolled in strongly linking educational programs. Moreover, VET systems are far from homogeneous, and there are large differences in how strong educational programmes link to occupations within and between countries. In general, employment is highest among the stronger linking programs, and this effect is strongest in dual VET systems. These results suggest that there is still room for occupationally oriented schooling.
Magnetic resonance imaging for pathobiological assessment and interventional treatment of the coronary arteries

X-ray-based fluoroscopy is the standard tool for diagnostics and intervention in coronary artery disease. In recent years, computed tomography has emerged as a non-invasive alternative to coronary angiography offering detection of coronary calcification and imaging of the vessel lumen by the use of iodinated contrast agents. Even though currently available invasive or non-invasive techniques can show the degree of vessel stenosis, they are unable to provide information about biofunctional plaque properties, e.g. plaque inflammation. Furthermore, the use of radiation and the necessity of iodinated contrast agents remain unfavourable prerequisites. Magnetic resonance imaging (MRI) is a radiation-free alternative to X-ray which offers anatomical and functional imaging contrasts fostering the idea of non-invasive biofunctional assessment of the coronary vessel wall. In combination with molecular contrast agents that target-specific epitopes of the vessel wall, MRI might reveal unique plaque properties rendering it, for example, ‘vulnerable and prone to rupture’. Early detection of these lesions may allow for early or prophylactic treatment even before an adverse coronary event occurs. Besides diagnostic imaging, advances in real-time image acquisition and motion compensation now provide grounds for MRI-guided coronary interventions. In this article, we summarize our research on MRI-based molecular imaging in cardiovascular disease and feature our advances towards real-time MRI-based coronary interventions in a porcine model.
Research on a balanced circuit and control strategy
Authors: Zhang LingChao
Published: April 2020

For reducing the inconsistent state of charges (SOC) of lithium-ion battery cells and making the full use of battery packs, effective battery balancing technology should be used. In order to achieve the goal of balancing any single cell in the battery pack expediently and considering the cost and the balance efficiency, a balanced circuit is proposed. By changing the action state of single-pole double-throw relay connected to each of the single cell battery, the balanced single-cell battery is in a state of non-load power supply, at this point, the balanced battery is in `charging’ state compared with other batteries in the battery pack, thus achieving the balance target of the battery pack. On this basis, this paper also proposes a new balancing control strategy; it is different from the traditional control strategy to balance the SOC of the single cell to the SOC average of the battery pack, considering the different SOC change rates of the cells with different capacity in the battery pack. The balanced control strategy proposed in this paper allows the set condition of the single cell to end the equilibrium process in advance so as to reduce the unnecessary balance time and then improve the equilibrium speed. In order to verify the feasibility of the proposed circuit and control strategy, 18 650 batteries with different initial SOC in series are experimentally verified. The experimental results show that the balanced circuit proposed in this paper can well balance the cell of each single cell and make the battery pack reach a balanced state.

Background

Bacterial vaginosis (BV) is a common cause of vaginal discharge and associated with vaginal acquisition of BV-associated bacteria (BVAB).

Methods

We used quantitative polymerase chain reaction assays to determine whether presence or concentrations of BVAB in the mouth, anus, vagina, or labia before BV predict risk of incident BV in 72 women who have sex with men.

Results

Baseline vaginal and extra-vaginal colonization with Gardnerella spp, Megasphaera spp, Sneathia spp, BVAB-2, Dialister sp type 2, and other BVAB was more common among subjects with incident BV.

Conclusions

Prior colonization with BVAB is a consistent risk for BV.
