Published: October 2021

Aims
Impaired renal function is a major contributor to the low proportion of mineralocorticoid receptor antagonist (MRA) treatment in patients with heart failure with reduced ejection fraction (HFrEF). Our aims were to investigate the impact of MRA treatment on all-cause mortality and worsening renal function (WRF) in patients with HFrEF and moderately impaired renal function.

Methods
Retrospective data between 2010–2018 on HFrEF patients from a single-centre hospital with estimated glomerular renal function (eGFR) < 60 ml/min/1.73 m2 were analysed. WRF was defined as a decline of by eGFR ≥ 20%.

Results
416 patients were included, 131 patients on MRA and 285 without MRA, mean age was 77 years (SD ± 9) and 82 years (SD ± 9), respectively. Median follow-up was 2 years. 128 patients (32%) experienced WRF, 25% in the MRA group and 30% in patients without MRA (p = 0.293). In multivariable analysis, hospitalization for heart failure and systolic blood pressure were associated with WRF (p = 0.015 and p = <0.001), but not use of MRA (p = 0.421). MRA treatment had no impact on the risk of adjusted all-cause mortality (HR 0.93; 95% CI, 0.66–1.32 p = 0.685). WRF was associated with increased adjusted risk of all-cause mortality (HR 1.43; 95% CI, 1.07–1.89 p = 0.014). Use of MRA did not increase the adjusted overall risk of mortality even when experiencing WRF (HR 1.15; 95% CI, 0.81–1.63 p = 0.422).

Conclusion
In this cohort of elderly HFrEF patients with moderately impaired renal function, MRA did not increase risk for WRF or all-cause mortality.

Published: October 2021

Background
Pharmaceuticals wastes are drugs and medicines that can no longer be used. The improper disposal of unused medicines is a growing problem throughout the world. This study assessed the pharmaceutical wastage rate and pharmaceutical waste management for the year 2015 to 2017 in the public health facility of Dessie, Ethiopia.

Methodology
A cross-section study design was used to review logistic data retrospectively from health commodity management information systems and manual records in 8 health facilities. Health professionals’ (135) pharmaceutical waste management practices were assessed using the world health organization waste management checklist. Descriptive and inferential statistics were made using a statistical package for social sciences version 20.

Result
Supplies were the leading class of pharmaceuticals with an overall wastage rate of 37.1%. Tablet and injectable constituted the highest class of pharmaceuticals dosage form with the overall wastage rate of 20.78% and 16.49%. The overall pharmaceutical wastage rate was 3.68% amounting to USD 159,762.66 and expiry (92.05%) was the major reason for wastage. The pharmaceutical wastage rate of health centers was nearly twofold higher than hospitals. Pharmaceutical waste management was practiced by 105 (77%; 95% CI; 69.9%, 84.9%) health professionals. Determinants of pharmaceutical waste management were being male (P value = 0.08, AOR = 3.72), receiving training (P value = 0.01, AOR = 4.34), writing label (P value = 0.02, AOR = 5.04), storage of segregated waste in dispensing unit (P value = 0.01, AOR = 0.72) and the presence of disposal plan (P value = 0.002, AOR = 16.93).

Conclusions
Supplies and tablets constituted the highest wastage class of pharmaceuticals and dosage form. The pharmaceutical wastage rate was higher than the standard and increasing in successive years. Pharmaceutical waste management was not fully practiced. Appropriate inventory control and waste management are recommended.

Studies on the Ammatowa indigenous people have been carried out by several researchers. Unfortunately, none of these studies have focused on the role and position of women in the Ammatowa people, both in their daily lives and in regard to education. Therefore, this study fills that void. This study aims to identify the position and role of women in the life of the Ammatowa people; what specific roles are performed by women in customary areas; and how the traditions are still firmly held provide space for women to express themselves. As a study of a unique community, this study uses an ethnographic approach, by collecting, classifying, and analyzing the various positions of women in the Ammatowa Kajang community. In the traditional structure of Tana Towa, women have an important, strategic and respected position. In the structure of these customs, there is an important role played by a woman called Angrota who has the task and responsibility of preparing all the needs for traditional ceremonies, facilitating the selection of Ammatowa and inaugurating them. In the economic aspect, women have an important role in supporting the family’s financial, such as weaving, selling in the market, and farming. Meanwhile, education for Tana Towa women is still a major issue that needs serious attention. It is because the education world is related to issues of customs, and the family economy.
Demonstration of apperception

Many recent video applications---including traffic monitoring, drone analytics, autonomous driving, and virtual reality---require piecing together, combining, and operating over many related video streams. Despite the massive data volumes involved and the need to jointly reason (both spatially and temporally) about these videos, current techniques to store and manipulate such data are often limited to file systems and simple video processing frameworks that reason about a single video in isolation.
We present Apperception, a new type of database management system optimized for geospatial video applications. Apperception comes with an easy to use data model to reason about multiple geospatial video data streams, and a programming interface for developers to collectively reason about the entities observed in those videos. Our demo will let users write queries over video using Apperception and retrieve (in real-time) both metadata and rendered video data. Users can also compare results and observe speedups achieved by using Apperception.
Interactive demonstration of SQLCheck

Published: October 2021

We will demonstrate a prototype of sqlcheck, a holistic toolchain for automatically finding and fixing anti-patterns in database applications. The advent of modern database-as-a-service platforms has made it easy for developers to quickly create scalable applications. However, it is still challenging for developers to design performant, maintainable, and accurate applications. This is because developers may unknowingly introduce anti-patterns in the application's SQL statements. These anti-patterns are design decisions that are intended to solve a problem, but often lead to other problems by violating fundamental design principles.
sqlcheck leverages techniques for automatically: (1) detecting anti-patterns with high accuracy, (2) ranking them based on their impact on performance, maintainability, and accuracy of applications, and (3) suggesting alternative queries and changes to the database design to fix these anti-patterns. We will demonstrate that sqlcheck enables developers to create more performant, maintainable, and accurate applications. We will show the prevalence of these anti-patterns in a large collection of queries and databases collected from open-source repositories.

Database management systems (DBMSs) are notoriously difficult to deploy and administer. Self-driving DBMSs seek to remove these impediments by managing themselves automatically. Despite decades of DBMS auto-tuning research, a truly autonomous, self-driving DBMS is yet to come. But recent advancements in artificial intelligence and machine learning (ML) have moved this goal closer.Given this, we present a system implementation treatise towards achieving a self-driving DBMS. We first provide an overview of the NoisePage self-driving DBMS that uses ML to predict the DBMS's behavior and optimize itself without human support or guidance. The system's architecture has three main ML-based components: (1) workload forecasting, (2) behavior modeling, and (3) action planning. We then describe the system design principles to facilitate holistic autonomous operations. Such prescripts reduce the complexity of the problem, thereby enabling a DBMS to converge to a better and more stable configuration more quickly.
Towards scalable online machine learning collaborations with OpenML
Authors: Vanschoren Joaquin 
Published: October 2021

Is massively collaborative machine learning possible? Can we share and organize our collective knowledge of machine learning to solve ever more challenging problems? In a way, yes: as a community, we are already very successful at developing high-quality open-source machine learning libraries, thanks to frictionless collaboration platforms for software development. However, code is only one aspect. The answer is much less clear when we also consider the data that goes into these algorithms and the exact models that are produced. A tremendous amount of work and experience goes into the collection, cleaning, and preprocessing of data and the design, evaluation, and finetuning of models, yet very little of this is shared and organized in a way so that others can easily build on it.
Suppose one had a global platform for sharing machine learning datasets, models, and reproducible experiments in a frictionless way so that anybody could chip in at any time to share a good model, add or improve data, or suggest an idea. OpenML is an open-source initiative to create such a platform. It allows anyone to share datasets, machine learning pipelines, and full experiments, organizes all of it online with rich metadata, and enables anyone to reuse and build on them in novel and unexpected ways. All data is open and accessible through APIs, and it is readily integrated into popular machine learning tools to allow easy sharing of models and experiments. This openness also allows a budding ecosystem of automated processes to scale up machine learning further, such as discovering similar datasets, creating systematic benchmarks, or learning from all collected results how to build the best machine learning models and even automatically doing so for any new dataset. We welcome all of you to become a part of it.
‘Smelling’ diasporic: bargaining interactions and the problem of politeness
Authors: Wagner Lauren 
Published: October 2021

AbstractWhile post-migrant generation Moroccans from Europe often are able to converse competently enough in Moroccan languages to bargain in shops during visits to Morocco, many report that they are not given the ‘local’, ‘right’ prices because they are ‘smelled’ as outsiders. During fieldwork following these diasporic visitors in Morocco, several participants strategically shopped for goods with a ‘local’ friend or family member who might negotiate on their behalf for the ‘right’ price. This strategy was seen as a way to circumvent or ameliorate the ways the diasporic client might be negatively categorized as an outsider, especially in terms of his or her language use. Yet, examining these events in recorded detail indicates that diasporic clients are often bargaining for themselves as competent speakers, but are sometimes not able to skillfully bargain politely. In these moments, proxy bargainers intervene when debate and tension increases during bargaining and diasporic visitors do not adequately perform politeness – specifically by deploying religious speech – to soften and minimize tension. Analysis of these interactions indicates how diasporic branching of linguistic practice contrasts communicative skills of mobile populations with subtle, place-based competences, and how the mismatch between these can negatively mark diasporic visitors.

Abstract

Objectives
To assess the influence of frame rate settings on longitudinal strain (LS) and mechanical synchrony (SYN) values in Speckle Tracking Echocardiography (STE) of healthy fetuses.

Methods
In this prospective study, we collected transversal or apical four-chamber-views of 121 healthy fetuses between 20 and 38 weeks of gestation using three different frame rate (FR) settings (≥ 110, 100 ± 10, 60 ± 10 frames per second). We assessed the segmental and the global LS of both ventricles (2C) and of the left ventricle (LV) offline with QLab 10.8 (Philips Medical Systems, Andover, MA, USA). Inter- and intraventricular SYN were calculated as time difference in peak myocardial strain between the mid-segments of left and right ventricle (interventricular, 2C_Syn) and lateral wall and septum of the left ventricle (intraventricular, LV_Syn), respectively.

Results
In 84.3% STE was feasible at all three FR settings. The LS increased in both views at higher FRs to a statistically noticeable extent. SYN measurements and the absolute differences at patient level between the FR settings showed no statistically noticeable alterations.

Conclusions
STE is feasible at low and high FR settings. SYN emerges to be a robust parameter for fetal STE as it is less affected by the FR. High FRs enable high temporal resolutions and thus an accurate examination of fetal hearts. Future research for the technical implementation of tailored fetal STE software is necessary for reliable clinical application.
Emotional positioning in British news reports about Dover and Essex migrant tragedies: A corpus-based study
Authors: Yang Qinyi 
Published: October 2021

AbstractThis article, based on the Appraisal System, investigates British journalists’ different attitudes toward China and Vietnam in British news reports about the Dover migrant tragedy in 2000 and the Essex migrant tragedy in 2019. By analyzing affect resources in a newly built corpus with the help of UAM Corpus Tool 3.3, this study finds that more negative affect resources are used to portray China than those depicting Vietnam. British journalists manipulated emotions to emphasize that China, whether in 2000 or 2019, was a backward and underdeveloped country where citizens tried all means to escape to Britain. However, when British journalists found that the victims were Vietnamese instead of Chinese, they shifted attention to the pitiful Vietnamese families of the victims and tended to arouse readers’ sympathy. The corpus findings highlight the ideological contradiction between Britain and China, reveal Britain’s distrust of China’s system, and suggest that the different comprehensive national powers of China and Vietnam have different impacts on Britain’s international status, verifying that news discourse is permeated by ideology, politics, and economy.
A diffusion Monte Carlo method for charge density on a conducting surface at non-constant potentials
Authors: Yu Unjong , Jang Hoseung , Hwang Chi-Ok 
Published: October 2021

Abstract
We develop a last-passage Monte Carlo algorithm on a conducting surface at non-constant potentials. In the previous researches, last-passage Monte Carlo algorithms on conducting surfaces with a constant potential have been developed for charge density at a specific point or on a finite region and a hybrid BIE-WOS algorithm for charge density on a conducting surface at non-constant potentials. In the hybrid BIE-WOS algorithm, they used a deterministic method for the contribution from the lower non-constant potential surface. In this paper, we modify the hybrid BIE-WOS algorithm to a last-passage Monte Carlo algorithm on a conducting surface at non-constant potentials, where we can avoid the singularities on the non-constant potential surface very naturally. We demonstrate the last-passage Monte Carlo algorithm for charge densities on a circular disk and the four rectangle plates with a simple voltage distribution, and update the corner singularities on the unit square plate and cube.

Letture e lezioni frontoniane nell’epistolario di Simmaco
Authors: Fascione Sara 
Published: October 2021

Abstract
This study aims to define the ways in which the work of Fronto circulated and was used in the intellectual circles of the fourth century A.D. through the testimony offered by the letters of Symmachus. In addressing illustrious members of the senatorial aristocracy of his time, Symmachus echoes Fronto’s work several times. The examination of Symm. Ep. 3.11 to Naucellius, with special reference to the expression spectator tibi veteris monetae solus supersum in Symm. Ep. 3.11.2, allows us to evaluate how Symmachus approaches the work of Fronto. The ways in which the short treatise ad M. Aurelium de orationibus is reprised lead us, further, to conclude that the lexical choices of the fourth-century letter-writer were determined by a textual variant in the text of Fronto available to him.
An autonomous and wireless pulse-amplitude modulated chlorophyll fluorometer

Published: October 2021

AbstractMeasuring chlorophyll fluorescence is an important tool in plant research, since it is a reliable non-invasive method for capturing photosynthetic efficiency of a plant and, hence, an indicator of plant stress/health. The principle of chlorophyll fluorometry is based on the optical illumination of a plant’s leaf at a certain wavelength, while simultaneously measuring the emitted fluorescence light intensity at a different optical wavelength. By relating the fluorescence light energy at small and large excitation power, conclusions on the efficiency of the photosystem and, therefore, on the plant’s photosynthesis capability can be drawn. Current mobile chlorophyll fluorometers are either (i) compact and energy efficient but limited in functionality and accuracy by omitting modulated measurement signals or (ii) sophisticated and precise with respect to the measurement, but with the drawback of extended weight, size, energy consumption and cost. This contribution presents a smaller, lighter and cheaper sensor device that can be built with sufficiently low energy consumption to be powered by energy harvesting while being light enough to be attached nearly anywhere such as tree branches. With a device cost below 250 €, the performance of the developed device is similar to more expensive commercial devices considering measurements of the relative variable fluorescence. Moreover, the sensor device provides a wireless interface in the European 868 MHz SRD band with up to 10 km of range in free space while just consuming 150 µW in receiving mode due to a custom duty cycling technique.
Biochar for the removal of detected micropollutants in South African domestic wastewater: a case study from a demonstration-scale decentralised wastewater treatment system in eThekwini

The presence of micropollutants, such as pharmaceuticals and personal care products, in surface and ground water has escalated globally, leading to adverse effects on aquatic organisms in receiving waters. Untreated or inadequately treated wastewater is the main source of micropollutants entering the environment. In South Africa, the consumption of antibiotics and antiretroviral drugs is relatively higher than other nations; however, little data exists on the identification and remediation of micropollutants in domestic wastewater. In this study, a novel method to detect and measure 71 micropollutants using online solid phase extraction liquid chromatography coupled to tandem mass spectrometry was developed. To test the method in the South African context, grab samples of the influent and anaerobically treated effluent (AF effluent) from a demonstration-scale decentralised wastewater treatment system in eThekwini (Durban) were taken over 3 consecutive days at 2 time points. The presence of 24 micropollutants was detected in the raw wastewater, with analgesics/anti-inflammatory drugs, antiretrovirals, and antibiotics showing the highest concentrations and with the majority of compounds still present in the AF effluent. One antibiotic, ciprofloxacin, exceeded its predicted no-effect concentration in all influent and AF effluent samples. This suggests that the anaerobic treatment of the raw wastewater was not effective in removing micropollutants. Preliminary data from lab-scale adsorption experiments using biochar produced from a set of 4 feedstocks – olive residues, tomato residues, rice husks, and the African palm tree Raphia farinifera – showed average removal rates for 4 compounds of up to 62%. The application of biochar is thus recommended as a secondary treatment step in decentralised wastewater treatment for the removal of micropollutants in South Africa.
Materials from Dwelling 2 on Suchu Island, the Lower Amur (1977 Season, Excavation III)
Authors: Medvedev V. E. , Filatova I. V. 
Published: October 2021

This article presents the fi nal results of excavations at one of the largest Neolithic sites in northeastern Asia— a settlement on Suchu Island on the Amur. Most of the rich collection (3967 spec.), owned by IAET SB RAS (stone tools, ceramics, ornaments, and artistic and ritual artifacts), has not been described before. This publication focuses on the analysis of artifacts from dwelling 2 (excavation III, 1977). We describe the construction of this semi-underground dwelling, circular in plan view. The typological analysis of the lithics indicates a complex economy. Many of them (arrowheads, projectile points, inserts, knives, plummets) relate to hunting and fi shing, and to processing carcasses (end-scrapers, scrapers, burins, combination tools), others are chopping tools. The distinctive feature of the lithics is that some are bifacial. The analysis of the ceramics suggests that they belong to the Late Neolithic Voznesenovskoye culture. The use of binocular microscopy allowed us to assess the technological and constructive properties of the ceramics, as well as their morphological, decorative, and functional features. Non-ut ilitarian artifacts shed light on the worldview of the Suchu people. The collection dates to the mid-second millennium BC.
