Social capital and its role to improve maternal and child health services in Northwest Ethiopia: A qualitative study
Authors: Mengesha Endalkachew Worku , Tessema Gizachew A. , Assefa Yibeltal , Alene Getu Degu 
Published: April 2023

Background
Social capital is a set of shared values that allows individuals or groups receive emotional, instrumental or financial resources flow. In Ethiopia, despite people commonly involved in social networks, there is a dearth of evidence exploring whether membership in these networks enhances uptake of maternal and child health (MCH) services. This study aimed to explore perspectives of women, religious leaders and community health workers (CHWs) on social capital to improve uptake of MCH services in Northwest Ethiopia.

Methods
We employed a qualitative study through in-depth interviews with key informants, and focus group discussions. A maximum variation purposive sampling technique was used to select 41 study participants (11 in-depth interviews and 4 FGDs comprising 7–8 participants). Data were transcribed verbatim and thematic analysis was employed using ATLAS.ti software.

Results
Four overarching themes and 13 sub-themes of social capital were identified as factors that improve uptake of MCH services. The identified themes were social networking, social norms, community support, and community cohesion. Most women, CHWs and religious leaders participated in social networks. These social networks enabled CHWs to create awareness on MCH services. Women, religious leaders and CHWs perceived that existing social capital improves the uptake of MCH services.

Conclusion
The community has an indigenous culture of providing emotional, instrumental and social support to women through social networks. So, it would be useful to consider the social capital of family, neighborhood and community as a tool to improve utilization of MCH services. Therefore, policymakers should design people-centered health programs to engage existing social networks, and religious leaders for improving MCH services.
Prevalence of refractive error in Portugal estimated from ophthalmic lens manufacturing data: Ten-years analysis
Authors: Alves Carneiro Vera L. , González-Méijome José Manuel 
Published: April 2023

Purpose
To investigate the prevalence, distribution and trends of refractive error from ophthalmic lens manufacturing data over a ten-year period.

Methods
Fully anonymized data from ophthalmic lenses, for the years between 2010 and 2020, provided by the leading ophthalmic lens manufacturer operating in Portugal were analysed (no human participants were involved in the research). Prescriptions delivered were divided in single vision prescriptions and progressive/multifocal prescriptions and categorized into 14 spherical equivalent ranges. Given the lack of absolute values, indirect estimates and a qualitative analysis of the current situation and trends on refractive error epidemiology was carried out.

Results
Dataset from manufacturer comprises percentage values of ophthalmic lenses dispensed in Portugal. The distribution of ophthalmic prescriptions for single vision prescriptions presents most of the observations in the range [-1.49, -0.50] diopters, in every year from 2010 to 2020. For the progressive prescription’s lenses, most of the observations is in an interval of two ranges, [0.50, 1.49] and [1.50, 2.99] diopters. From 2010 to 2020 the proportion of single vision ophthalmic lens prescriptions for myopia increased from 38.13% to 46.21%; the proportion for high myopia increased from 2.76% to 4.45%; and the proportion for hyperopia decreased from 40.85% to 31.36%.

Conclusions
Ophthalmic lens manufacturing data can be a valuable source for long-term analysis of refractive error prescription and trends over time. It was possible to observe a trend of increasing prevalence of myopia and high myopia from 40.89% in 2010 to 50.66% in 2020. That increase trend has important implications for public health and in the planning of services.
Chinese synthetic verbs: a further challenge to manner/result complementarity on the basis of lexical root meaning analysis
Authors: Li Tianyu 
Published: April 2023

Abstract
This paper introduces Chinese synthetic verbs and analyses their contributions to debates in manner/result complementarity studies and cognitive typology studies. Chinese synthetic verbs simultaneously express manner information and path/result information, but encode them into separate root slots under Beavers and Koontz-Garboden’s (2012. Manner and result in the roots of verbal meaning. Linguistic Inquiry 43(3). 331–369) scopal modifier test, so they differ from English “manner+result verbs” and further challenge the manner/result complementarity hypothesis. Synthetic verbs followed by redundant path/result verbs constitute double-framing structures that twice encode the framing information, and the non-motion case, i.e., the “synthetic verb+result verb” structure, supplements Croft et al.’s (2010. Revising Talmy’s typological classification of complex event constructions. In Hans C. Boas (ed.), Contrastive studies in construction grammar, vol. 10, 201–235. Amsterdam & Philadelphia: John Benjamins Publishing Company) classification that only includes the motion case, so that Chinese synthetic verbs complement the discussion on double-framing structures. This paper thereby further falsifies the manner/result complementarity hypothesis and provides an overall illustration of the double-framing structure in cognitive typology. This paper also illustrates the diachronic changes of manner, which might be universal and await further investigation.
Enhanced design of PI controller with lead-lag filter for unstable and integrating plus time delay processes
Authors: Kumar Sanjay , Ajmeri Moina 
Published: April 2023

Abstract
In this work, a proportional–integral (PI) controller with a set point filter is designed using the direct synthesis method for unstable plus time delay process. The Suggested method involves design parameters whose suitable values are recommended based on robust stability and robust performance constraints. The absence of derivative term makes PI controllers less sensitive to noise and, therefore, PI controllers are more preferable than PID in industrial applications. Despite a simple control architecture, the proposed method gives improved or comparable performance to previously presented approaches, which are comparatively complex. Four case studies are considered to evaluate the suitability and superiority of the suggested control technique. Proposed controller may be applied to the integrating plus time delay plants after some elementary transformations in the process model.
Reverse droop control strategy with virtual resistance for low-voltage microgrid with multiple distributed generation sources
Authors: Raj Devaraju Chethan , Prakash Dadadahalli Basavaraju , Lakshminarayana Chaluvaiah 
Published: April 2023

AbstractIn the island operation mode of the microgrid, the rated capacity and feeder impedance of each parallel distributed generation inverter are different and the output power is difficult to be reasonably distributed when the traditional droop control strategy is adopted, which reduces the stability of the system. In order to solve this problem, the power transmission characteristics of low-voltage microgrid are analyzed and the leading factors affecting the reasonable power distribution are obtained. A control strategy of virtual resistor is proposed and the difference between the actual output power and the expected output power is used to control the power compensation coefficient and proportional integration to adjust the reference voltage of each DG inverter. The control strategy can automatically adjust the change in the output power of the distributed power supply in real time, adjust the voltage change caused by the line impedance mismatch in time, improve the power quality, reduce the system circulation, and realize the reasonable distribution of power. Finally, the simulation model verifies the effectiveness of the strategy.
On the survival of the Spanish absolute construction: a qualitative diachronic study based on a corpus of translations from Latin
Authors: Molenaers Marie 
Published: April 2023

Abstract
This article studies the diachronic behaviour of the non-finite verbal (participial, gerundial) absolute construction (AC) in (pre)classical and modern Spanish translations from Latin, written between the 15th and the 18th centuries. It focuses on the convergence of and divergence between the ACs of the Spanish target texts and those of the Latin source texts, drawing on three types of translations: (i) Latin absolute constructions translated as Spanish absolutes (translated ACs), (ii) Latin absolute constructions translated as Spanish constructions other than absolutes (non-translated ACs) and (iii) Spanish absolute constructions that do not stem from Latin absolutes (ex-novo ACs). The article traces a diachronic evolution of the AC in terms of formal and functional equivalence, or creativity, and links the results to the cultural-historical context. The analysis shows that the nearly extinct, (pre)classical participial AC developed from a ‘marked’ Latin calque situated at the far end of the Communicative Distance pole to a less formal, gerundial AC, moving in the direction of Communicative Immediacy. This process of syntactic elaboration concurred with the AC’s increased frequency and was caused by language-internal mechanisms such as structural priming and form/function overlap with gerundial free adjuncts (FAs). From the 15th century onwards, a growing tendency towards unbounded construals enabled the gerundial AC to become fully entrenched in early modern Spanish, which guaranteed the survival of this construction.
Investigating willingness to communicate in synchronous group discussion tasks: one step closer towards authentic communication
Authors: Nematizadeh Shahin , Cao Yiqian (Katherine) 
Published: April 2023

Abstract
This study employed a mixed-method approach to investigate L2 WTC as a dynamic variable in synchronous group discussion tasks. Data were collected from a group of Farsi-speaking ESL students in six online discussion tasks. The participants rated their WTC level every 5 min during the discussions and then provided explanations for changes in WTC in follow-up written stimulated recall procedures. The results indicate that participants’ WTC levels fluctuate significantly during the online discussion tasks, lending support to viewing online WTC as a fluid dynamic variable. The results also show that WTC changes are triggered by complex interactions between a range of internal and external forces. Pedagogical implications and directions for future research are discussed.
Bit slicing approaches for variability aware ReRAM CIM macros

Published: April 2023

Abstract
Computation-in-Memory accelerators based on resistive switching devices represent a promising approach to realize future information processing systems. These architectures promise orders of magnitudes lower energy consumption for certain tasks, while also achieving higher throughputs than other special purpose hardware such as GPUs, due to their analog computation nature. Due to device variability issues, however, a single resistive switching cell usually does not achieve the resolution required for the considered applications. To overcome this challenge, many of the proposed architectures use an approach called bit slicing, where generally multiple low-resolution components are combined to realize higher resolution blocks. In this paper, we will present an analog accelerator architecture on the circuit level, which can be used to perform Vector-Matrix-Multiplications or Matrix-Matrix-Multiplications. The architecture consists of the 1T1R crossbar array, the optimized select circuitry and an ADC. The components are designed to handle the variability of the resistive switching cells, which is verified through our verified and physical compact model. We then use this architecture to compare different bit slicing approaches and discuss their tradeoffs.
Narrow bandpass filter using Octonacci photonic quasicrystal
Authors: Abohassan Khedr M. , Daher Malek G. , Taya Sofyan A. , Panda Abinash , Prajapati Yogendra K. 
Published: April 2023

Abstract
In this paper, we propose structures for tunable narrow bandpass optical filters covering the visible range of 400–800 nm. The transmittance spectra of s-polarized (TE mode) light in one-dimensional photonic crystals are obtained by using a theoretical calculation based on the transfer matrix method. Here, photonic crystals and photonic quasicrystals composed of Si and SiO2 are organized according to some generations of the Octonacci sequence. The number of output channels and their central wavelengths are found to be dependent on the generation number and the angle of incidence. The results show an increase in the quality factor as the angle of incidence increased. Therefore, the proposed structures are believed to be suitable for efficient narrow bandpass filters operating in the visible range.

Abstract

Objectives
Early diagnosis in Turner syndrome is desirable to optimize growth and puberty and yet, it is often made late. Here, we aim to identify age at diagnosis, clinical features at presentation and potential strategies to improve the care of TS girls.

Methods
Retrospective study, including patients from 14 care centers across Tunisia including neonatal and pediatric care units, adult endocrinology and genetics departments.

Results
We identified 175 patients with TS, karyotype showing 45, xmonosomy in 83(47.4 %) with mosaicism in 37(20 %). Mean ± SD, median (range) age at diagnosis available in 173 patients was 13 ± 9.2,12 (birth-48) years. The diagnosis was antenatal in 4(2.3 %), from birth-2 years in 14 (8 %)with lymphoedema (8)and dysmorphic features (9),2–12 years in 53 (35.5 %) including 35 with short stature, 13–18 years in 43(28.8 %) with short stature(28) and delayed puberty(14) and 35(23.5 %) after 18 years, related to ovarian insufficiency (20) and short stature (11). The associated malformations were cardiac in 14 (12.8 %), renal in 22 (19.6 %). A total of 56 girls (32 %) had proven gonadal dysgenesis and 13 (7 %) had otological problems. Parental height was available in 71 girls (40 %) of whom 59 were below the lower end of parental target range (LTR) (83 %).

Conclusions
This first Tunisian multicenter study, the first African of its kind, reveals that more than half of Turner syndrome cases are diagnosed after the age of 12 years. Subsequently, national strategies for an earlier TS diagnosis are needed such as measuring and plotting parental heights as well as introducing a systematic height screening at 5 years in Tunisia with a view to carrying out a re-audit in five years’ time.
Impact of tool rotational speed on the microstructural transitions and tensile properties of the dissimilar AZ80A-Mg – AA6061-Al joints fabricated by friction stir welding
Authors: Lokesh Kumar P. J. , Sevvel P. , Loganathan T. G. 
Published: April 2023

Abstract
Distinct AZ80A-Mg alloy with AA6061-Al alloy plates were joined using friction stir welding and investigation regarding the weld features of the fabricated joints, related to microstructural attributes and mechanical properties was carried out by employing distinctive tool rotational speeds (1600, 1400, 1200, 1000 and 800 rpm). Tool possessing cylindrical pin with tapered profile was employed at constant traverse speed of 30 mm/min and was inserted towards AA6061 alloy plate at 0.5 mm offset distance. Experimental observations revealed that employment of tool rotational speed of 1200 rpm have generated ideal amounts of frictional heat, which have softened the ingredients of both the parent metals and have contributed for the transition of the grains into dynamically recrystallized, finely refined structures being distributed evenly in nugget zone. Moreover, this joint exhibited a tensile strength of 224 MPa (nearly 77.78 % of the tensile strength of AZ80A and 72.26 % of AA6061 alloy). Presence of river like patterns, rifts, tear crinkles at the middle portions of fractured surfaces, announced the brittle category of fracture of the flaw free joint and exhibited fracture at the horizon of the thermomechanically influenced zone and the nugget zone on retreatment side, where the warped structures have fused together.

Published: April 2023

Abstract

Objectives
This study aims to determine the effects of Hericium erinaceus extracts on cell viability and the effects of H. erinaceus water extract on the telomerase activity of MCF-7 cells. H. erinaceus is an edible mushroom widely used in traditional Chinese medicine. Although its various therapeutic properties, the literature has not yet submitted evidence about H. erinaceus for its effects on the telomerase activity of MCF-7 cells.

Methods
MCF-7 cells were treated with ethanol, ethanol-water, ether, ethyl acetate, methanol-water, and water extracts to determine the effects on cell viability using the WST8 method. The TeloTAGGG Telomerase PCR ELISA kit was used to assess telomerase activity.

Results
The water extract was determined to be the most efficient extract to decrease cell viability. The water extract’s half-maximal inhibitory concentration was 250 μg/mL at 72 h. It is found that H. erinaceus has no statistically significant effect compared to positive control on reducing telomerase activity. We found a statistically significant difference in telomerase activity % between H. erinaceus water extracts and negative control (p<0.05).

Conclusions
Consequently, these differences in telomerase activity are a significant association rather than inferring action. It is considered that water extract shows its cell viability inhibition effects through different mechanisms.

Abstract
Eosin Y (EY) is a toxic dye and has adverse effects on human beings as well as on aquatic organisms. During the last few decades, various methods such as physio-chemical and biological methods have been reported for the degradation of this toxic dye. Many researchers reported degradation of EY using different polymer stabilized metal nanoparticles synthesized employing green methods. Mono-metallic nanoparticles (MNPs) stabilized by polymeric systems are the most widely used tools for the degradation of many toxic dyes including EY. Characterization as well as morphology assessment of the nanoparticles is done by different analytical techniques including UV-visible, FTIR, SEM, TEM and XRD. In this review article, synthesis, characterization, chemistry of the polymeric stabilized nanoparticles has been reported. In addition, mechanism, kinetics and thermodynamics of catalytic degradation of EY using polymeric stabilized nanoparticles, have been discussed. This review also carries the discussion on various nano catalytic systems which have been used for the degradation of EY to link the most recent work on water purification from EY dye. This review will be helpful in understanding the spectrum of already published work describing role of polymeric stabilized nanoparticles for EY degradation. It will also motivate researchers to design their future work and commercial applications of polymeric stabilized nanoparticles.

Unabhängigkeit der Finanzmarktaufsicht
Authors: Gurlit Elke 
Published: April 2023

Zusammenfassung
Das deutsche Modell einer ministeriell gesteuerten Verwaltung gerät zunehmend unter Druck. Denn im europäischen und internationalen Vergleich ist der Typus der „independent agency“, die allein dem Parlament verantwortlich ist, weit verbreitet. Nachdem das Unionsrecht schon die politische Unabhängigkeit der mitgliedstaatlichen Datenschutzaufsicht und der Bundesnetzagentur erzwungen hat, erteilte nunmehr das BVerfG in seinem Urteil zur Bankenunion der unionsrechtlich geforderten Entlassung der BaFin in den ministerialfreien Raum seinen verfassungsrechtlichen Segen, soweit die Bundesanstalt im Rahmen des Einheitlichen Europäischen Aufsichts- und Abwicklungsmechanismus tätig ist. Der Beitrag analysiert die unions- und verfassungsrechtlichen Vorgaben zur Rechtsstellung der europäischen und deutschen Finanzmarktaufsichtsbehörden und bewertet die Leistungsfähigkeit der divergierenden Modellannahmen. Im Ergebnis plädiert er dafür, die BaFin vollständig von der Rechts- und Fachaufsicht durch das Bundesfinanzministerium zu befreien.
