Topological classification of billiards bounded by confocal quadrics in three-dimensional Euclidean space
Authors: Belozerov G. V. 
Published: December 2021

Abstract
We study billiards on compact connected domains in

bounded by a finite number of confocal quadrics meeting in dihedral angles equal to

. Billiards in such domains are integrable due to having three first integrals in involution inside the domain. We introduce two equivalence relations: combinatorial equivalence of billiard domains determined by the structure of their boundaries, and weak equivalence of the corresponding billiard systems on them. Billiard domains in

are classified with respect to combinatorial equivalence, resulting in 35 pairwise nonequivalent classes. For each of these obtained classes, we look for the homeomorphism class of the nonsingular isoenergy 5-manifold, and we show this to be one of three types: either

, or

, or

. We obtain 24 classes of pairwise nonequivalent (with respect to weak equivalence) Liouville foliations of billiards on these domains restricted to a nonsingular energy level. We also define bifurcation atoms of three-dimensional tori corresponding to the arcs of the bifurcation diagram.

Published: December 2021

Abstract
The quaternionic Stiefel manifold

is the total space of a fibre bundle over the corresponding Grassmannian

. The group

acts freely on the fibres of this bundle. The quotient space is called the quaternionic projective Stiefel manifold. Its real and complex analogues were actively studied earlier by a number of authors. A finite group acting freely on the three-dimensional sphere also acts freely and discretely on the fibres of the quaternionic Stiefel bundle. The corresponding quotient spaces are called partially projective Stiefel manifolds.
The cohomology rings of partially projective quaternionic Stiefel manifolds with coefficients in

Significance
Endocytosis transports cargos inside the cell by creating spherical vesicles from the plasma membrane. This membrane remodeling requires proteins to generate force to bend the membrane inwards, overcoming the high-turgor pressure in plant cells. However, as plants create clathrin-coated vesicles without actin, the machinery to bend membranes during endocytosis is entirely unknown and appears distinct from other model systems. Here, we refine the physiological role of the plant-specific and essential endocytic TPLATE complex. We find it localizes outside of clathrin-coated vesicles and mediates membrane bending, contrasting with previous predictions. We further demonstrate that the TPLATE complex contains protein domains which have intrinsic membrane-bending activity; thus, we identify a component of the unique endocytosis membrane-bending machinery in plants.
Hyperentanglement teleportation through external momenta states
Authors: Ali Liaqat , -ul-Islam Rameez , Ikram Manzoor , Abbas Tasawar , Ahmad Iftikhar 
Published: December 2021

Abstract
The conventional teleportation protocol requires a state entangled in only one degree of freedom (DOF), while hyperteleportation requires more than single DOF to complete the task. The hyperteleportation schematics are demonstrated only for the photonic systems, where in the present paper we extend the idea to a hyperteleportation protocol involving the atomic internal and external states. The protocol is deterministically engineered through resonant and off-resonant atomic Bragg diffraction involving two-level neutral atoms under standard cavity-QED working environment. Moreover, the longer interaction time Bragg’s regime with well separated transverse momenta states as an output of the neutral atoms guarantees the high enough engineering fidelities with reduced decoherence rates. The experimental parameters for the demonstration of the proposed scheme are also elucidated briefly describing the optimistic feasibility for the experimental execution of the proposed schematics.

Published: December 2021

Abstract
Based on the problem where the intensity of an excitation source is not easy to regulate using the traditional active control method, this paper presents an accurate temperature control system based on a micro-hotplate for the first time. This system realizes the active control of terahertz functional devices, and implements various functions by using the proposed accurate temperature control process. The temperature control characteristics of the micro-hotplate are introduced into the design of terahertz functional devices by taking a vanadium dioxide (VO2) terahertz absorber as an example. In this design, a silicon-based micro-hotplate is used to heat the terahertz absorber. According to the phase transition characteristics of VO2, the alteration of temperature leads to a conductivity change, so as to realize the active control of the absorber. At the same time, this paper also analyzes the heating and cooling time of the micro-hotplate. The simulation results show that, by using the micro-hotplate to heat the terahertz functional devices, the temperature adjustment speed is reasonably high and the controllable performance is excellent. The test results show that the surface temperature can be controlled between 40 °C and 80 °C, and the temperature difference of the working area can be kept within 1 °C. The temperature control of the micro-hotplate is accurately controlled, resulting in excellent performance of the terahertz functional devices.
A reliability evaluation framework for smart meters based on AGG-ARIMA and PFR
Authors: Ma Lisha , Meng Zhiqiang , Teng Zhaosheng , Qiu Wei 
Published: December 2021

Abstract
The unavoidable outliers and the characteristics of the small sample dataset affect the performance of the failure rate (FR) prediction and reliability analysis model of smart meters (SMs). To solve these problems, we choose the basic error (BE) as the performance index of the equipment and propose a reliability evaluation framework for SMs by combining adaptive Gauss genetic-algorithm-autoregressive integrated moving average (AGG-ARIMA) and proportional FR (PFR) for the first time. First, the ARIMA model is used to predict the BEs to describe the performance of SMs. Then, an AGG is used to optimize the order of ARIMA and a PFR model is established to analyze the reliability of batch SMs through the BE predictions. Finally, actual datasets from four companies are used to verify the effectiveness of our evaluation framework. The experimental results show that our framework has better reliability assessment performance for SMs under small sample conditions, and has strong adaptability to the analysis of individual meters.
Confinement improvement during detached phase with RMP application in deuterium plasmas of LHD

Abstract
In order to explore the compatibility of good core plasma performance with divertor heat load mitigation, the interaction between cold edge plasma and core plasma transport, including the edge transport barrier (ETB), has been analysed in the divertor detachment discharges of deuterium plasmas in LHD with resonant magnetic perturbation (RMP) field application. The RMP application introduces a widened edge stochastic layer and sharp boundary in the magnetic field structure between the confinement region and the edge stochastic layer. The widened edge stochastic layer enhances impurity radiation and provides stable detachment operation as compared with the case without RMP. It is found that ETB is formed at the confinement boundary at the onset of detachment transition. However, as the detachment deepens, the resistive pressure gradient-driven MHD mode is excited, which degrades the ETB. At the same time, however, the core transport decreases to keep global plasma stored energy (W
p) unchanged, showing clear core-edge coupling. After a gradual increase of density fluctuation during the MHD activity, a spontaneous increase of W
p and the recovery of ETB are observed while the detachment is maintained. Then, the coherent MHD mode ceases and ELM-like bursts appear. In the improved mode, impurity decontamination occurs, and the divertor heat load increases slightly. Key controlling physical processes in the interplay between core and cold edge plasma are discussed. A comparison between deuterium and hydrogen plasmas shows that hydrogen plasmas exhibit similar features to the deuterium ones in terms of density and magnetic fluctuations, impurity decontamination towards higher confinement, etc. But most of the features are modest in the hydrogen plasmas and thus no clear confinement mode transition with clear ETB formation is defined. Better global confinement is obtained in the deuterium plasmas than the hydrogen ones at a higher radiation level.
Single-trial detection of EEG error-related potentials in serial visual presentation paradigm
Authors: Parashiva Praveen K , Vinod A P 
Published: December 2021

Abstract
When the outcome of an event is not the same as expected, the cognitive state that monitors performance elicits a time-locked brain response termed as Error-Related Potential (ErrP). Objective—In the existing work, ErrP is not recorded when there is a disassociation between an object and its description. The objective of this work is to propose a Serial Visual Presentation (SVP) experimental paradigm to record ErrP when an image and its label are disassociated. Additionally, this work aims to propose a novel method for detecting ErrP on a single-trial basis. Method—The method followed in this work includes designing of SVP paradigm in which labeled images from six categories (bike, car, flower, fruit, cat, and dog) are presented serially. In this work, a text (visual) or an audio clip describing the image in one word is presented as the label. Further, the ErrP is detected on a single-trial basis using novel electrode-averaged features. Results - The ErrP data recorded from 11 subjects’ have consistent characteristics compared to existing ErrP literature. Detection of ErrP on a single-trial basis is carried out using a novel feature extraction method on two type labeling types separately. The best average classification accuracy achieved is

for the audio and visual type of labeling the image, respectively. The proposed feature extraction method achieved higher classification accuracy when compared with two existing feature extraction methods.

To conclude the article, the authors present a brief further prospective on this new domain, highlighting existing gaps that are specifically related to artificial intelligence technologies, such as explainability, cost-effectiveness, and, of course, the importance of proper regulatory oversight for each clinical implementation.
Reflections on the usefulness of today’s atrial fibrillation ablation procedure endpoints and patient-reported outcomes
Authors: Blomström-Lundqvist Carina , Svedung Wettervik Victoria 
Published: December 2021

Abstract
The improvement of Patient-reported outcomes, such as health-related quality of life, is the main indication for atrial fibrillation ablation. Despite this guideline derived indication for an AF ablation procedure the current standardized primary endpoint in AF ablation trials is still rhythm-related, and primarily a 30-second long AF episode. The review presents reflections on the non-rational arguments of using rhythm related endpoints rather than Patient-reported outcomes in AF ablation procedure trials despite the mismatch between many of the rhythm related variables and symptoms. Arguments for health-related quality of life as the most optimal primary endpoint in clinical trials are presented while atrial fibrillation burden is presented as the most optimal electrical complementary endpoint, apart from being the major variable in mechanistic trials.

Abstract

Aims
School-based routine screenings of electrocardiograms (ECGs) have been performed upon admission to primary school (PS), junior high school (JHS), and high school (HS) in Japan. Though ECGs with prolonged QT intervals are occasionally found, the role of regular ECG screening tests in identifying long QT syndrome (LQTS) remains to be determined. We investigated the usefulness of the ECG screenings by comparing the results of genetic tests between students who showed QT-prolongation in the screenings and patients with LQTS.

Methods and results
We genetically screened 341 students (106 PS, 173 JHS, and 62 HS). Of these, 230 subjects showed QT-prolongation during regular screenings (S-S group), and the other 111 patients were clinically consulted with suspected LQTS by paediatricians (C-C group). Genotype–phenotype relationships were compared between the two groups. The positive rates in the genetic tests were comparable among the two groups; however, symptomatic subjects were significantly fewer in the S-S group than the C-C group (3% vs. 70%). Compared to the genotype-negative subjects, the positive subjects showed significantly longer QTc (P &lt; 0.0001) and more frequently presented LQTS risk scores with ≥3.5 points (P &lt; 0.0001). Lethal arrhythmic events (LAE) occurred only in the C-C group; 18 subjects experienced LAE and 83% of them were found to carry variant(s) in the LQTS-related genes.

Conclusion
The school-based ECG screenings are effective in identifying young patients with LQTS who require genetic analysis. If individuals are screened at a younger age, we can identify patients at risk earlier and provide preventative treatments.
PS interferometric imaging condition for microseismic source elastic time-reversal imaging
Authors: Zhou Yicheng , Zhang Qingshan , Zhang Wei 
Published: December 2021

SUMMARYThe time-reversal imaging method utilizes the wave equation to back-propagate recorded seismic data and a proper imaging condition to locate a passive seismic source. For an explosive source, the reconstructed wavefield is focused at the seismic source location and origin time. Although the elastic time-reversal wavefield for a moment tensor source may not exhibit a maximum at the true location at the origin time, it does exhibit a quasi-symmetrical spatial distribution around the source location that represents the radiation pattern of the moment tensor source. We propose the use of an interferometric imaging condition to solve the radiation pattern problem, which is combined with elastic PS cross-correlation imaging condition (referred to as the PS interferometric cross-correlation imaging condition) to locate a moment tensor source using elastic time-reversal imaging method. 2-D and 3-D numerical tests demonstrate that our proposed method can identify the moment tensor source location in complex velocity models with a high noise level. In tests of the sensitivity of the method to the accuracy of the velocity model, we find that the method can still get focused images under about 10–25 per cent random perturbations in P- and S-wave velocities, but only under about 5 per cent correlated perturbation of global P- and S-wave velocities with a potential bias in the location.
Conflict and synergy in health promotion partnerships: a Danish case study
Authors: Holt Ditte Heering , Højlund Holger , Jensen Heidi A R 
Published: December 2021

SummaryIntersectoral partnerships constitute a central approach in health promotion. By combining different perspectives, knowledge and resources from different sectors, partnerships are important for addressing complex health problems. When successful, intersectoral partnerships create synergy, which is suggested to be a proximal outcome that links partnership functioning to health effects. Nonetheless, partnerships are also difficult and time-consuming and may result in conflicts, hostility and power struggles. Such antagonist outputs are expected to produce negative results. However, conflicts may also be a source of valuable learning. This article explores the relationship between conflict and synergy in health promotion partnerships. The empirical material is derived from an evaluation of a 4-year Danish government partnership program. Data consist of survey data collected from 35 partnerships and in-depth qualitative case studies of 10 partnerships. The analysis was inspired by realist evaluation. The qualitative data were coded, and cases written up. Cross-case analysis was conducted and triangulated with survey data. Surprisingly, disagreements and conflicts of interests between partners were common and associated with synergy creation. Moreover, the partnerships’ experiences of synergy were often linked to their attribution of differences rather than to common goals or value congruences. The study identifies that a potential for synergy lays in the productive confrontation between partners different perspectives. Moreover, a key mechanism enabling productive conflicts was inclusive dialog, in which the partners’ differences were valued, and all voices were included. The study thus builds on the existing synergy literature and adds nuance to the understanding of conflicts in health promotion partnerships.
The scope and concerns of public health
Authors: Detels Roger , Tan Chorh Chuan 
Published: December 2021

Abstract
Public health is the art and science of preventing disease, prolonging life, and promoting health through the organized efforts of society. The goal of public health is the biological, physical, and mental well-being of all members of society. Thus, public health must address the challenge of confronting health problems, as well as political, social, and economic factors affecting health, not only at the community, state, and national levels, but also at the global level. This chapter introduces the reader to the scope and current major concerns of public health in the twenty-first century, giving examples of each. It is the goal of this chapter to assist the reader in understanding the conceptual framework of the field, which will help them in placing the subsequent more detailed chapters into the context of the entire field of public health.
The history and development of public health in developed countries
Authors: Szreter Simon 
Published: December 2021

Abstract
It has been conventional to locate the origins of public health in early efforts to combat epidemics and to regulate the sanitary environment accompanying urban life and to trace its history in the gradual evolution of such measures in relation to politics, administrative practices, public laws, and medical science’s changing aetiology. Such an historical account provides important insights and understanding but it is also de-limited in one significant sense. Public health is cast in a responsive role in relation to the processes of economic development. However, the nature of the relationship between public health and global economic development can appear very differently when it is viewed over the long-term, encompassing the whole process of modern economic transformation from the singular matrix of its origins in the early modern society and economy of England, c.1600–1800. This chapter will show that state policies to promote the social order, security, and health of the population in fact pre-date and crucially underpinned the process through which the modern world’s economic transformation originated—in early modern England.
Globalization
Authors: Lee Kelley 
Published: December 2021

Abstract
Globalization, defined as the closer interconnectedness of human societies across national borders and geographies, through a mixture of spatial, temporal, and cognitive changes, is having wide-ranging impacts on public health. This interconnectedness is characterized by restructuring of the world economy, increased population mobility, and advances in information and communication technology, all of which can have profound impacts on health determinants and outcomes. Contemporary globalization creates new opportunities to enhance human health and well-being, but can also be a potential source of negative externalities. In addition, the costs and benefits to health from globalization have been inequitably distributed. A ‘global public health’ approach seeks to better understand the changing patterns of health and disease, and their determinants, arising from globalization, and the interventions needed to effectively manage them. This requires greater attention to achieving collective action, underpinned by legal and regulatory frameworks, across populations and societies to tackle transboundary health determinants and outcomes. More effective global health governance, in turn, will contribute to more sustainable forms of globalization.
