Meteorology influencing springtime air quality, pollution transport, and visibility in Korea

In an environment with many local, remote, persistent, and episodic sources of pollution, meteorology is the primary factor that drives periods of unhealthy air quality and reduced visibility. The 2016 Korea-United States Air Quality (KORUS-AQ) field study provides a unique opportunity to examine the impact of meteorology on the relative influence of local and transboundary pollution. Much of the KORUS-AQ campaign can be grouped into four distinct research periods based on observed synoptic meteorology, including a period of complex aerosol vertical profiles driven by dynamic meteorology, stagnation under a persistent anticyclone, low-level transport and haze development, and a blocking pattern. These episodes are examined using a diverse archive of ground, airborne, and satellite data. While frontal boundaries are recognized as the primary mechanism driving pollution transport in eastern Asia, results show that they are not always related to sustained periods of hazardous air quality and reduced visibility at the surface. Significant long-range transport of pollution and dust was constrained to a few short events, suggesting that the majority of pollutants sampled during KORUS-AQ originated from local sources. A severe regional pollution episode is examined in detail, featuring dense haze and significant secondary particle formation within a shallow moist boundary layer. Observations during KORUS-AQ also highlight a rapid, 40 ppbv increase in ozone pollution as a strong sea breeze front traversed the Seoul Metropolitan Area. Representativeness of meteorology and pollution conditions measured by KORUS-AQ is considered by comparison with climatology. This analysis is an essential step toward improved local and regional forecasting of air quality and visibility.
Maximal amplitudes of hyperelliptic solutions of the derivative nonlinear Schrödinger equation

A simple formula is proven for an upper bound for amplitudes of hyperelliptic (finite‐gap or N‐phase) solutions of the derivative nonlinear Schrödinger equation. The upper bound is sharp, viz, it is attained for some initial conditions. The method used to prove the upper bound is the same method, with necessary modifications, used to prove the corresponding bound for solutions of the focusing NLS equation (Wright OC, III. Sharp upper bound for amplitudes of hyperelliptic solutions of the focusing nonlinear Schrödinger equation. Nonlinearity. 2019;32:1929‐1966).
Adaptive finite‐time tracking control for robotic manipulators with funnel boundary

The finite‐time tracking control problem with the output‐constraint property of robotic manipulators subjected to system uncertainties is addressed. Specifically, the radial basis function neural network is employed to compensate for system uncertainties. The finite‐time stability theorem is used for the backstepping design process, by which the limit of the settling time is set. A funnel boundary is used to limit the output overshoot. The proposed controller guarantees that all the signals are semi‐globally practically finite‐time bounded, while the tracking errors are enveloped by the funnel boundary. The performance of the proposed control method is illustrated by a numerical simulation of a 3‐DOF manipulator. It is shown that the tracking errors are bounded by prescribed funnel boundaries. In the meantime, the manipulator is stabilized within a finite period of time.
Motion control of self-driving vehicles on rough roads

Control of self-driving vehicles is one of the-up-to-date tasks. Vehicles are non-linear dynamic systems with a large number of parameters. When it is supposed to move on a rough road with a lot of abrupt turns, significant unpredictable and unmeasurable disturbances emerge and the control quality degrades significantly. We implemented model predictive path integral (MPPI) control to deal with significant unmeasured disturbances. To approve efficiency of the proposed controller, we conducted simulation of complex car motion on a plane under the control of PID, and MPPI controllers. Performance of controllers is comparatively equal in stable modes, when reference position and velocity do not change. MPPI controllers outperform PID ones in unstable modes due to their ability to predict a vehicle behavior. Also, MPPI is the best choice for the rejection of significant external disturbances.
Understanding community responses to tourism gentrification in Seochon Village in South Korea: the significance of parental, social, and cultural factors

ABSTRACT Drawing on qualitative interviews with residents in Seochon Village, South Korea, this study investigates the conditions by which residents could develop community attachments and could therefore lead to collective action to safeguard the village. The results of this study suggest that the common identities of residents as parents of children in the village; social capital promoted by activities, events, and shared spaces; and the cultural capital of highly educated activists in organizations have interactively played a role in fostering residents’ attachment to Seochon and thus in facilitating collective actions to negotiate with the local Jongno-gu district office.
Relationship between levels of Copeptin, NTproBNP and structural functional parameters of the heart in patients with acute myocardial infarction with ST-segment elevation complicated by pulmonary hypertension

Introduction: Acute Myocardial Infarction with ST-Segment Elevation (STEMI) - one of the major causes of morbidity and mortality worldwide, including in Ukraine. The prevalence of pulmonary hypertension (PH) in STEMI significantly is not known due to lack of epidemiological studies in this area. Currently, the prognostic significance of PH in patients with STEMI is not set. Objective: To evaluate the levels of NTproBNP and Copeptin and their relationship with structural and functional features of the heart in patients with STEMI complicated by PH. Materials and Methods: The study involved 85 patients (49 men and 36 women) with STEMI who were treated in intensive care and emergency cardiology for the treatment of patients with myocardial infarction communal non-profit enterprise "City hospital and emergency ambulance" Zaporizhia city council. Patients were divided into two groups: 53 patients with STEMI in the presence of PH (mean age 72,40 ± 2,26 years), 32 patients with STEMI without PH (mean age 67,30 ± 2,12 years). Results: In assessing the clinical anamnesis (Table 1) found that PH mainly develops in the anterior localization of STEMI (73,6%). In patients with STEMI in the presence of PH compared with patients without significant PH frequently observed violations systolic function (64,2%). Significant increasing in the level of copeptin (p <0,05) were found in the serum of patients with acute myocardial infarction in the presence of PH compared with patients with normal pressure in the pulmonary artery (PA). NTproBNP level was also higher in patients with STEMI and PH compared with patients without PH. In patients with STEMI and PH we found reliable positive correlation between the NTproBNP and copeptin level (+0,31; p <0,05), systolic pressure in PA (0,41; p <0,05) and negative correlation between NTproBNP level and ejection fraction (-0,41; p <0,05), stroke volume (-0,42; p <0,05). Copeptin positively correlated with the level of NTproBNP (+0,31; p <0,05), systolic pressure in PA (0,37; p <0,05) and negatively correlated with ejection fraction (-0,30; p <0,05 ). Conclusions: Pulmonary hypertension develops mainly in the anterior localization of STEMI (73,6%) in the presence of systolic dysfunction (64,2%). In patients with STEMI and PH level of NTproBNP and copeptin in serum were increased compared than patients without PH. In patients with STEMI and PH NTproBNP and copeptin levels correlated with decreased left ventricular ejection fraction and increased pressure in the pulmonary artery.
A Multi-Indicator Multi-Output Mixed Frequency Sampling Approach for Stock Index Forecasting

Compared to stock price index sampled at higher frequency, its indicators are usually sampled at lower frequencies. In practice, with higher frequency variables response to lower frequency variables, we can get multi-output for each period. This paper explores how to construct a multi-indicator multi-output (MIMO) mixed sampling frequency approach for stock price index forecasting. We also consider nonlinear relationship between dependent variables and independent variables in stock market. We establish a new model by applying multiple output support vector machine (MSVM) to modify mixed data sampling (MIDAS). We compare results with other models and make DM tests. The experiment shows that the proposed model performances better.

Discrete‐time [𝒦,𝒦ℒ] sector based hands‐off control for nonlinear system

This article presents a hands‐off control design for discrete‐time nonlinear system with a special type of nonlinear sector termed as “discrete‐time [𝒦,𝒦ℒ] sector. ” The design method to define the boundary of a discrete‐time [𝒦,𝒦ℒ] sector is done with control‐Lyapunov function. The generalization of nonlinear system is viewed in the perspective of a comparison function. By means of a proposed sector, a switching control is designed such that no control action is experienced inside the sector thus, saving unnecessary control efforts. However, to study the robustness for discrete‐time system, a hands‐off control is modified to ensure the monotonic decrease in the energy of the system. Finally, the proposed approach is verified with the simulation results.

STIG: Generation and simulated sequencing of synthetic T cell receptor repertoires

T cell receptor repertoire inference from DNA and RNA sequencing experiments is frequently performed to characterize host immune responses to disease states. Existing tools for repertoire inference have been compared across publicly available biological datasets or unpublished simulated sequencing data. Evaluation and comparison of these tools is challenging without common data sets created from a known repertoire with well-defined biological and sequencing characteristics. Here we introduce STIG, a tool to create simulated T cell receptor sequencing data from a customizable virtual T cell repertoire, with clear attribution of individual reads back to locations within their respective T-cell receptor clonotypes. STIG allows for robust performance evaluation of T cell repertoire inference and downstream analysis methods. STIG is implemented in Python 3 and is freely available for download at https://github.com/Benjamin-Vincent-Lab/stig Author summary As part of the acquired immune system, T cells are integral in the host response to microbes, tumors and autoimmune disease. These cells each have a semi-unique T cell receptor that serves to bind a set of antigens that will in turn stimulate that cell to perform its particular pro- (or anti) inflammatory role. This receptor is the product of DNA rearrangement of germline gene segments, similar to B cell receptor loci rearrangement, which provides a wide variety of potential T cell receptors to respond to antigens. At the site of an immune reaction, T cells can increase their number through clonal expansion and methods have been developed to analyze bulk genetic sequencing data to infer the individual receptors and the relative size of their clonal subpopulations present within a sample. To date, these methods and tools have been tested and compared using either biological samples (where the true quantitiy and types of T cells is unknown) or unshared synthetic datasets. In this paper I describe a new tool to generate biologically-inspired T-cell repertoires in-silico and generate simulated sequencing data from them.
Evaluation of Trunk-Supporting Exoskeleton

Trunk Supporting Exoskeletons are increasingly being evaluated in workplaces as viable ergonomic interventions for reducing the risk of back injuries. A series of trunk-supporting exoskeletons have been designed and built at the University of California at Berkeley and suitX. These exoskeletons decrease the forces on the wearer’s back at L5/S1 location. This article describes one of these exoskeletons, referred to as backX, and its evaluation method. backX is designed not only to reduce the forces and torques on the wearer’s back at L5/S1 location, but also to allow the wearer to perform all kinds of maneuvers such as walking, squatting, ascending and descending stairs, slopes and ladders, riding bicycles and driving trucks. This study finds that average muscle activities of the thoracic and lumbar erector spinae muscles among equal populations of male and female subjects, wearing backX while maintaining forward bending postures, are reduced by 75% and 56% respectively. The results of this study and extended field evaluations indicate that wearing backX minimizes the risk of back injuries among workers who repeatedly go through stooping, squatting, and bending postures for various tasks, such as lifting objects.
Stochastic modeling of a technological process using histogram computation

The focus of research is a discrete-event simulation model of the production process, including many technological operations, the time duration of which should be considered as a random function of several discrete variables. It is assumed that a limited amount of available statistics allows us to construct estimating distribution functions of the random function concerned only for individual values of its arguments. The estimates obtained in this way are suggested in order to be used to form the estimating distribution functions of the random function for any values of its arguments by the methods of histogram arithmetic. Results of the use of the proposed approach, implemented within a computer simulation model of a transport technological process are considered.
Compliance with Continuous Positive Airway Pressure (CPAP) Therapy in a Dedicated Sleep Clinic Population

Obstructive sleep apnea syndrome (OSAS) is characterized by repeated cessations of breathing during sleep. Most patients suffering from OSAS are treated with continuous positive airway pressure (CPAP) as the first line of therapy. Overall, noncompliance to CPAP can range from 29-83%. In this study of 135 patients, we aimed to evaluate the role of sleep clinics in factors improving adherence to CPAP. Initially, patients had a compliance of 72.6%, but after one year or more overall compliance was 85.9%. Remarkably, the most significant difference was seen in the Medicaid population, whose compliance increased by 26.6%. Considering the well-established benefits of CPAP in patients with OSAS, we determined that a close follow up in a dedicated sleep clinic improves overall compliance especially in the Medicaid population. CPAP mask change was the most successful intervention that improved compliance.
Physical Scattering Interpretation of POLSAR Coherency Matrix by Using Compound Scattering Phenomenon

The <inline-formula> <tex-math notation="LaTeX">$2\times 2$ </tex-math></inline-formula> relative scattering matrix <inline-formula> <tex-math notation="LaTeX">$[S]$ </tex-math></inline-formula> is characterized by five elements (three amplitudes and two relative phases). A more suitable representation of the data in terms of power expression for target identification exists in the <inline-formula> <tex-math notation="LaTeX">$3\times 3$ </tex-math></inline-formula> Pauli-based polarimetric coherency matrix <inline-formula> <tex-math notation="LaTeX">$[T]$ </tex-math></inline-formula>. The aim of this work is to expand the physical interpretation of <inline-formula> <tex-math notation="LaTeX">$[T]$ </tex-math></inline-formula> elements in terms of a physical scattering mechanism, which has not yet been achieved completely. Compound scattering matrix nature is considered to interpret the elements of <inline-formula> <tex-math notation="LaTeX">$[T]$ </tex-math></inline-formula>. Compound scattering phenomenon, and thereby generated matrices, are verified with measured compound scattering matrices in an anechoic chamber by comparing measured and theoretical polarization signature responses. The behavior of measured polarization signature(s) is consistent with the theoretical/hypothetical polarization signature(s). It is also observed that the combination of two or more dipole-type targets formed the scattering generators and helped to reveal the unknown scattering mechanisms in the coherency matrix. Furthermore, the existence of compound scattering phenomenon is also justified with airborne and spaceborne fully polarimetric synthetic aperture radar (POLSAR) data by implementing recent physical model-based scattering power decomposition methods.
A Simple Non-Invasive Automated Heart Rate Monitoring System Using Facial Images

In this chapter we will discuss a simple non invasive automated heart rate monitoring method. Commonly heart rate is measured by using heart rate monitor devices. Many patients do not feel comfortable when they use contact devices for diagnostic purposes. Our algorithm gives a non-invasive way of heart rate measurement. The first step is to record a video. After 5 frames of the video are captured, the face is detected. A total of 300 frames will be used for further processing. At this stage, ROI (part of forehead) will be cropped out automatically. All image frames are in RGB color model, so these will be separated into 3 channels. For analysis, graph normalization is applied, which uses mean and standard deviation. Fast Fourier transform is used to plot the power spectrum of the traces. This power spectrum will have a peak if the heart rate is detected. We used RGB, HSI, YCbCr, YIQ, and CIE LAB color models for analysis. The best result is achieved with RGB color model followed by CIELab. The average accuracy is 95.32%.
Transfusion -Related Acute Lung Injury (TRALI): Incidence, Risk Factors and Outcome in The Cardiothoracic Intensive Care Unit

BACKGROUND: Transfusion –related acute lung injury (TRALI) is a life threatening complication of blood transfusion. Cardiac surgery under cardiopulmonary bypassis a risk factor for acute lung injury(ALI) . The term‟ possible TRALI ” is used when there are alternative risk factors for ALI in addition to blood transfusion. OBJECTIVES OF THE STUDY: To determine the incidence, outcome and risk factors of‟ possible TRALI ” in the cardiothoracic intensive care unit. MATERIALS AND METHODS: It was an observational prospective cohort study in patients who underwent cardiac surgery and received perioperative blood transfusion.Perioperative patient related,surgery related and transfusion related data were recorded. RESULTS: The incidence of ‟possible TRALI” was 5.4%. The APACHE 2 score (p= 0.032) and platelet transfusion (p=0.035) was significantly higher for the ‟possible TRALI” group compared to the no lung injury group. There was no mortality. The duration ofventilation and ICU stay was comparable between both the groups. CONCLUSION: The incidence of possible TRALI is high (5.4%) in cardiac surgery. The occurrence of TRALI is highest for platelet transfusion.
Deformation detection through the realization of reference frames

Abstract Hellenic Military Geographical Service (HMGS) has established and measured various networks in Greece which constitute the geodetic infrastructure of the country. One of them is the triangulation network consisting of about 26.000 pillars all over Greece. Classical geodetic measurements that held by the Hellenic Military Geographic Service (HMGS) through the years have been used after adjustment for the state reference frame which materializes the current Hellenic Geodetic Reference System of 1987 (HGRS87). The aforementioned Reference System (RS) is a static one and is in use since 1990. Through the years especially in the era of satellite navigation systems many Global Navigation Satellite System (GNSS) networks have been established. The latest such network materialized by HMGS is ongoing and covers until now more than the 2/3 of the country. It is referenced by International GNSS Service (IGS) permanent stations and consists a local densification IGS08 Reference Frame. Firstly, this gives the opportunity to calculate transformation parameters between the two systems and a statistical analysis of the residuals leads to intermediate conclusions. After that and in conjunction with existing past transformations, tectonic deformations and their directions are concluded. Moreover past GPS observations on the same pillars in compare to the newer ones give also a sense of tectonic displacements. Greece is one of the most tectonically active countries in Europe and the adoption of a modern kinematic or semi-kinematic geodetic datum is a necessity as it should incorporate a deformation model like 3d velocities on the reference frame realization. The detection of geodynamic changes is a continuous need and should be taken into consideration at each epoch.
