Machine Learning–Based Feasibility Checks for Dynamic Time Slot Management
Authors: van der Hagen Liana , Agatz Niels , Spliet Remy , Visser Thomas R. , Kok Leendert 
Published: November 2022

Online grocers typically let customers choose a delivery time slot to receive their goods. To ensure reliable service, the retailer may want to close time slots as capacity fills up. The number of customers that can be served per slot largely depends on the specific order sizes and delivery locations. Conceptually, checking whether it is possible to serve a certain customer in a certain time slot given a set of already accepted customer orders involves solving a vehicle routing problem with time windows. This is challenging in practice as there is little time available and not all relevant information is known in advance. We explore the use of machine learning to support time slot decisions in this context. Our results on realistic instances using a commercial route solver suggest that machine learning can be a promising way to assess the feasibility of customer insertions. On large-scale routing problems it performs better than insertion heuristics. History: This paper has been accepted for the Transportation Science Special Issue on Machine Learning Methods and Applications in Large-Scale Route Planning Problems. Funding: This research was funded by the Netherlands Organization for Scientific Research under the City Logistics Living Laboratory project [Grant 439.18.424].
Near-perfect ultrabroadband metal-free ultrathin THz absorber
Authors: Varshney Gaurav , Gupta Ravi Raj , Sharma Ajay K. 
Published: November 2022

An ultrathin metal-free terahertz (THz) absorber is implemented and numerically analyzed. The absorber structure with a rectangular graphite resonator is designed to operate with the fundamental magnetic resonance in the lower- and higher-order magnetic resonance in the upper band. Carving the slots in the graphite resonator converts the magnetic resonance into the electric resonance at the upper frequency and merges the resonance spectra. The proposed absorber provides near-perfect flat broadband absorption of more than 99% in the 7.28–11.21 THz frequency range. Further, the absorber provides absorption of more than 90% and 80% in the 6.26–13.05 and 5.69–14.25 THz frequency range, respectively. The absorber structure utilizes a graphite-based resonator and backreflecting plane and provides the polarization insensitive response with the allowed incidence angle of more than 20° with the absorption more than 99%. The absorber response is validated through a transmission line method-based equivalent electrical circuit. Moreover, the reliability of the implemented absorber for its use in electromagnetic shields and stealth applications is calculated in terms of shielding effectiveness, which remains high in range of 50 to 250 dB.
The Cyber Resilience Act: the EU Commission’s proposal for a horizontal regulation on cybersecurity for products with digital elements
Authors: Chiara Pier Giorgio 
Published: November 2022

AbstractThe EU Commission presented on 15 September 2022 the proposal for a ‘Regulation on horizontal cybersecurity requirements for products with digital elements amending Regulation (EU) 2019/1020’ (Cyber Resilience Act, CRA). This long-awaited piece of legislation would complement EU cybersecurity acquis by laying down horizontal cybersecurity requirements for all products with digital elements. This article sheds light on the ‘horizontal’ character of the CRA proposal by highlighting its main pillars. In particular, the contribution takes into account the new set of obligations placed on economic operators, the conformity assessment procedures as well as the market surveillance framework and the interplay with other legislative initiatives, both in the policy area and outside EU cybersecurity law. Against the backdrop of the sectoral regulatory approach adopted thus far by the Commission vis-à-vis cybersecurity requirements for products, horizontal intervention is needed to ensure legal certainty, avoiding duplicative obligations and further market fragmentation.

Published: November 2022

BackgroundMaternity services around the world have been disrupted since the outbreak of the COVID-19 pandemic. The International Confederation of Midwives (ICM) representing one hundred and forty-three professional midwifery associations across the world sought to understand the impact of the pandemic on women and midwives.AimThe aim of this study was to understand the global impact of COVID-19 from the point of view of midwives’ associations.MethodsA descriptive cross-sectional survey using an on-line questionnaire was sent via email to every midwives’ association member of ICM.Survey instrumentThe survey was developed and tested by a small global team of midwife researchers and clinicians. It consisted of 106 questions divided into seven discreet sections. Each member association was invited to make one response in either English, French or Spanish.ResultsData were collected between July 2020 and April 2021. All respondents fulfilling the inclusion criteria irrespective of whether they completed all questions in the survey were eligible for analysis. All data collected was anonymous. There were 101 surveys returned from the 143 member associations across the world. Many countries reported being caught unaware of the severity of the infection and in some places, midwives were forced to make their own PPE, or reuse single use PPE. Disruption to maternity services meant women had to change their plans for place of birth; and in many countries maternity facilities were closed to become COVID-19 centres. Half of all respondents stated that women were afraid to give birth in hospitals during the pandemic resulting in increased demand for home birth and community midwifery. Midwifery students were denied access to practical or clinical placements and their registration as midwives has been delayed in many countries. More than 50% of the associations reported that governments did not consult them, and they have little or no say in policy at government levels. These poor outcomes were not exclusive to high-, middle- or low-income countries.ConclusionsStrong recommendations that stem from this research include the need to include midwifery representation on key government committees and a need to increase the support for planned out of hospital birth. Both these recommendations stand to enhance the effectiveness of midwives in a world that continues to face and may face future catastrophic pandemics.
Reference intervals for common clinical chemistry parameters in healthy adults of Northeast Ethiopia

Published: November 2022

Background
Clinical chemistry reference intervals are important tools for health evaluation, diagnosis, prognosis and monitoring adverse events. Currently used reference intervals in most African countries including Ethiopia are mainly derived from Western populations, despite studies reporting differences that could lead to incorrect clinical decisions. The aim of this study was to establish reference intervals for commonly used clinical chemistry parameters for healthy adults in Northeast Ethiopia.

Methods
A community based cross-sectional study was conducted among 328 apparently healthy adults between the ages of 18 and 57 years. Blood samples were collected for clinical chemistry analysis using Dirui CS-T240 auto-analyzer and serological testing to screen the population. Medians and 95% reference intervals were computed using non-parametric method according to the Clinical and Laboratory Standards Institute guideline. The Mann–Whitney U test was used to compare reference values between males and females.

Results
Reference intervals established were: ALT 11.2–48.0 U/L, AST 16–60 U/L, ALP 53–342.3 U/L, total protein 5.4–8.9 mg/dL, total bilirubin 0.1–1.23 mg/dL, glucose 65–125 mg/dL, total cholesterol 69–213 mg/dL, triglycerides 46–207 mg/dL, creatinine 0.3–1.2 mg/dL and urea 9.5–46.3 mg/dL. Significant sex-differences were observed for ALT, AST, ALP, total cholesterol, triglycerides, creatinine and urea. We found that the established reference intervals substantially differ from the reference ranges currently in use. Up to 43.1% of apparently healthy adults are considered as having abnormal test values on the bases of the currently in use reference ranges. If the reference values from the United States based intervals were applied to the study population, 81.8% would have been classified as having abnormal laboratory test results.

Conclusions
Local population-specific reference intervals were established for commonly used clinical chemistry parameters in adult population of Northeast Ethiopia. Although further study is needed, these reference intervals may have the potential to facility the decision-making process based on laboratory test results in this population.

One of the determinants of the success of learning Arabic for non-Arabic is the clarity of learning objectives according to their level. In this study, the reseacher described the goal of learning Arabic for non-Arabic in the West (Europe and America), and in Indonesia according to the 2013 curriculum. This paper uses a qualitative approach. Data obtained from various sources of literature and related documents. After describing the goal of learning Arabic for non-Arabic in European, American and Indonesian, the reseacher analyzed it with descriptive analysis. The results show that the purpose of learning Arabic in Indonesia as stated in the 2013 curriculum has not yet referred to a certain level, while the goal of learning Arabic in the West has been formulated according to its position as a foreign language and according to each level. It is hoped that this study will initiate curriculum developers in Indonesia, to formulate the objectives and standards of learning Arabic in accordance with its position as a foreign language in Indonesia according to its level. So that learning Arabic in Indonesia can be equal to learning Arabic at the international level as in Europe and America.

Salah satu faktor penentu suksesnya pembelajaran bahasa Arab untuk non-Arab-adalah tujuan pembelajaran yang jelas dan sesuai dengan levelnya. Problematika yang terjadi di Indonesia selama ini adalah, rendahnya kemampuan para pendidik dalam merumuskan tujuan pembelajaran bahasa Arab untuk non-Arab secara tepat. Dalam kajian ini, penulis mendeskripsikan tujuan pembelajaran bahasa Arab untuk non-Arab, di Barat (Eropa dan Amerika), dan di Indonesia (kurikulum 2013). Dengan demikian, kajian ini sangat penting bagi para pendidik bahasa Arab dalam memahami bagaimana merumuskan tujuan pembelajaran bahasa Arab untuk non-Arab. Tulisan ini menggunakan pendekatan kualitatif. Setelah mendeskripsikan tujuan pembelajaran bahasa Arab untuk non-Arab di Barat (Eropa dan Amerika) dan di Indonesia, penulis menganalisisnya dengan deskripstif analisis. Hasilnya menunjukkan bahwa tujuan pembelajaran bahasa Arab di Indonesia sebagaimana tertera dalam kurikulum 2013 belum mengacu pada tingkatan atau level tertentu. Sedangkan tujuan pembelajaran bahasa Arab di Barat, telah dirumuskan sesuai dengan posisinya sebagai bahasa Asing dan sesuai dengan level masing-masing. Diharapkan kajian ini dapat menginisiasi para pengembang kurikulum di Indonesia, untuk merumuskan tujuan pembelajaran bahasa Arab dan standarisasinya sesuai dengan posisinya sebagai bahasa Asing di Indonesia dan sesuai dengan levelnya, sehingga pembelajaran bahasa Arab di Indonesia dapat sejajar dengan pembelajaran bahasa Arab level internasional sebagaimana di Eropa dan Amerika.
