The past, present and future of indexing on persistent memory
Authors: Huang Kaisong , He Yuliang , Wang Tianzheng 
Published: September 2022

Persistent memory (PM) based indexing techniques have been proposed to build fast yet persistent indexes that sit on the memory bus. Over the past decade, numerous techniques have been proposed with various assumptions and different properties (e.g., some of them were proposed before real PM became available), making it hard for researchers and practitioners to gain a comprehensive understanding of the area.In this tutorial, we give a comprehensive overview of PM indexing techniques, covering both range and hash indexes. We contrast the designs proposed before and after real PM became available, summarize the common and useful design techniques, and discuss potential future challenges and opportunities in this area.

Published: September 2022

AbstractIntroductionDenture cleaners should not be harmful to dental prostheses elements, but immersions in cleaner solutions during a long time of using prosthesis may cause changes on Co–Cr alloy surfaces. There are five classes of denture cleaners: alkaline hypochlorites, alkaline peroxides, disinfectants, diluted acids, and enzymes. The aim of this work was to evaluate the influence of denture cleaners solutions on the surface properties of Co–Cr alloy.Materials and methodSpecimens cast from cobalt–chromium alloy were divided into eight groups: 1 – dry; 2 – ultrapure water; 3 – 20% wt/wt sodium; 4 – 20% chlorhexidine digluconate; 5 – Correga Tabs BioFormula; 6 – 20% wt/wt citric acid; 7 – 0.5% NaOCl; and 8 – 5.0% NaOCl. After immersion in 200 mL of cleaning agent solution at 45°C in 3 years, simulation of use, surface roughness, contact angle, surface free energy (SFE), and microscopic observation was performed.ResultsFor citric acid and NaOCl, roughness (Ra) raised clearly. These cleaning agents also causedRq,Rv,Rp, andRSmto increase the most. The observed water contact angle after using denture cleaners, especially citric acid, and NaOCl decreases, and the values of SFE increase. Under a digital microscope, the harmful effect of citric acid and solutions of NaOCl was visible.ConclusionsDiluted acids and alkaline hypochlorites in presented concentrations influence Co–Cr surface parameters like roughness and wettability. Other classes of denture cleaning agents do not affect surface roughness parameters which make them safer for the metallic components of removable partial dentures.

Abstract
Medical telemetry applications rely heavily on biomedical implanted antennas. These biomedical implanted devices can enhance and monitor patients’ daily life circumstances. A low-profile, downsized size implanted antenna operating at 915 MHz in the industrial, scientific, and medical (ISM) band is suggested in this research. The antenna is a simple slotted patch supplied by a 50-impedance coaxial probe. The radiator is made up of two slotted parasitic patches with one square-shaped outer radiator are manufactured on a Roger Droid RT5880 substrate with a standard height of 0.254 mm (ε
r = 2.2, tanδ = 0.0009). The entire dimension of the given antenna is 11 × 11 × 0.2514 mm with an electrical size of 0.049λ
g × 0.049λ
g × 0.0011λ
g. The antenna spans a bandwidth of 0.82–1.05 GHz when working inside muscle tissues (25.13 percent). The antenna’s calculations and experimental findings are quite similar. The computed specific absorption rate (SAR) values inside muscle of above 1 g mass tissue are 7.25 W/kg, according to the data. The stated SAR values are lower than the limit set by the Federal Communications Commission (FCC). As a result, the proposed small antenna is a strong contender for biological implantable applications.

In-situ leakage behavior of polymer-metal hybrids under mechanical load
Authors: Ott Constantin , Drummer Dietmar 
Published: September 2022

Abstract
Tightness against media is a frequent requirement for technical components. Despite various standardized test procedures, failure regularly occurs during use. Often, no clear cause for failure can be determined afterwards. In this article, a new test setup is presented and applied, which allows an in-situ measurement during a mechanical load. A flow meter with a measuring range of 0.02 mL/min to 5 mL/min is used for this purpose. This makes it possible to determine leakage rates with time resolution and thus to identify the moment of failure or the causal failure load. This new method was applied directly to different aluminum inserts with a polyamide 66 (PA66) overmold. It was shown that no increase in leakage occurs until a maximum force is reached, even with multiple loads. This maximum force depends only on the pretreatment of the inserts and can be determined in a simple pull-out test independently of the test setup used here and can therefore be used for the design of assemblies. In the test, a maximum force of 100 N was achieved for untreated inserts, 140 N for adhesion promoter-coated parts and 600 N for etched inserts with a contact area of 48 mm2. With this results, a new link between adhesion and tightness can be shown, which of course is only valid for initial tight parts.
Comparing the influence of foot reflexology and fasting mimicking diet on quality of life and sleep quality in obesity hypoventilation syndrome
Authors: Elbanna Rana Hesham Mohamed , Elabd Sherif Osama Abdelsalam , Alghitany Salma Ibrahim Abdelmohsen 
Published: September 2022

Abstract

Objectives
Obesity hypoventilation syndrome is one of the most serious outcomes of obesity-related respiratory difficulties, resulting in higher healthcare costs as well as increased cardio-respiratory morbidity and mortality.

Methods
Sixty-two males who had a high risk of obstructive sleep apnea according to the STOP-BANG Sleep Apnea Questionnaire were enrolled in the study. Their age is 50–60 years old, and they have a BMI of 35–40 kg/m2, daytime hypercapnia, and sleep breathing problems. The patients were divided into two equal groups at random reflexology fasting-mimicking diet groups. Weight, height, waist, and neck circumference were assessed at the beginning of the study and after two months of the intervention. Sleep quality was measured using the Pittsburgh Sleep Quality Index (PSQI), which is used to evaluate sleep quality. The Maugeri Obstructive Sleep Apnea Syndrome (MOSAS) questionnaire was used to assess a patient’s quality of life.

Results
There was a significant change in the MOSAS and PSQI questionnaires for both groups post-intervention, as the p-value was less than 0.05. The percentage change in the MOSAS questionnaire score and PSQI questionnaire was higher in the mimic diet group than in the reflexology group. Also, the mimic diet group’s weight and neck circumference were considerably reduced after the intervention, with no change in the reflexology group.

Conclusions
Reflexology and a fasting-mimicking diet were found to have a substantial impact on enhancing the quality of life and sleep in people with obesity hypoventilation syndrome.

Abstract

Objectives
Despite major advances in prevention, sudden infant death syndrome (SIDS) remains an important cause of infant mortality. The aim of our study was to determine actual knowledge and intentions to implement SIDS prevention measures among new mothers and to identify potential knowledge gaps for improved postpartum counselling strategies.

Methods
Data was collected in a standardized interview from participants of the KUNO-Kids birth cohort study before discharge from maternity ward. The mothers did not receive any specific teaching prior to the interview.

Results
The majority of 2,526 interviewed mothers were able to actively report important recommendations for safe infant sleep, including the exclusive face-up position. However, 154 mothers (9%) intended to position the newborn face-down sometimes or often. The most frequently envisaged sleeping furniture was a bedside sleeper (n=1,144, 47%), but 2.2% of mothers indicated that the intended default sleeping place for the newborn would be the parents’ bed (which is discouraged by the recommendations). For 43% of the infants (n=1,079), mothers planned to have loose objects in the bed and 189 mothers (7%) intended to use a loose blanket. 22% of infants (n=554) will live in a household with a smoker. Multivariate regression showed a significant association of “good knowledge” with maternal age and with not being a single parent, whereas the household size was negatively associated.

Conclusion
Although the majority of mothers in our birth cohort were aware of many recommendations for safe infant sleep, our data also uncovered weaknesses in SIDS prevention knowledge and point to specific areas with potential for improved counselling.
A (Long) Tale of Two Leaders: Charting the Spatial and Sectoral Roles of the West and China in Shaping Past, Present and Future Economic Globalization(s)
Authors: Chen Xiangming 
Published: September 2022

Abstract
Globalization has run into two intersected momentous shifts over the past decade. One is an accelerating retreat in the Western-led economic globalization. The other is the continued surge of China as a leader of alternative economic globalization, via the Belt and Road Initiative. These two powerful trends are complicated by COVID-19 and the Ukraine war with their disruptions of global geopolitics, plus a potential technological decoupling between China and the United States as great-power rivals. This unprecedented combination of challenges and crises occasions a fresh analysis of the roles of the West versus China in shaping economic globalization past and present. Against the state-centric approach to globalization, I develop a historically-informed framework to couple spatial and sectoral analyses of the trajectories of economic globalization shaped by the West and China. I first examine the cross-regional dimensions of economic globalization across Eurasia featuring China’s primary role in driving the China-Europe Freight Train. I then explore China’s exceptional strength in delivering overseas infrastructure projects, as embodied by the China-Laos Railway, relative to the West’s sectoral advantages bearing on economic globalization. Lastly, I summarily discuss the past and present roles of the West versus China in producing new divergence in future economic globalization.
A new rate of convergence estimate for homogeneous discrete-time nonlinear Markov chains
Authors: Shchegolev Aleksandr A. 
Published: September 2022

Abstract
In the paper, we study a new rate of convergence estimate for homogeneous discrete-time nonlinear Markov chains based on the Markov–Dobrushin condition. This result generalizes the convergence estimates for any positive number of transition steps. An example of a class of processes is provided to point that such estimates considering several transition steps may be applicable when one transition can not guarantee any convergence. Moreover, a better estimate can be obtained for a higher number of transitions steps. A law of large numbers is presented for a class of ergodic nonlinear Markov chains with finite state space that may serve as a basis for nonparametric estimation and other statistics.

Performance Analysis of ACO and FA Algorithms on Parameter Variation Scenarios in Determining Alternative Routes for Cars as a Solution to Traffic Jams
Authors: Sibaroni Yuliant , Prasetiyowati Sri Suryani , Fairuz Mitha Putrianty , Damar Muhammad , Salis Rafika 
Published: September 2022

This study proposes several alternative optimal routes on traffic-prone routes using Ant Colony Optimization (ACO) and Firefly Algorithm (FA). Two methods are classified as the metaheuristic method, which means that they can solve problems with complex optimization and will get the solution with the best results. Comparison of alternative routes generated by the two algorithms is measured based on several parameters, namely alpha and beta in determination of the best alternative route. The results obtained are that the alternative route produced by FA is superior to ACO, with an accuracy of 88%. This is also supported by the performance of the FA algorithm which is generally superior, where the resulting alternative route is shorter in distance, time, running time andÂ there is no influence on the alpha parameter value. But in each iteration, the number of alternative routes generated is less. The contribution of this research is to provide information about the best algorithm between ACO and FA in providing the most optimal alternative route based on the fastest travel time. The recommended alternative path is a path that is sufficient for cars to pass, because the selection takes into account the size of the road capacity.
A method for the mix design of low carbon concrete towards industrial production
Authors: Boscaro Federica , Flatt Robert J. 
Published: September 2022

AbstractThe introduction of newly developed blended cements into the mass market is essential to ensure an effective reduction of the carbon footprint related to cement production. To facilitate this process, formulating mix proportions using pastes and/or mortars rather than concrete can be a great advantage. However, for the upscaling towards industrial concrete it is then essential to maintain the target rheological and mechanical properties, something that is all too often challenging. In this work, a procedure facilitating such an upscaling was illustrated in the form of a flow chart. Specifically, best practices to obtain a good correlation between concrete prepared in a laboratory and one prepared in a plant were presented. This includes new data showing how to accommodate for possible differences in temperature and/or water content between both situations. The dataset of state-of-the-art correlations between mechanical performance and heat of hydration, considering w/b ratios relevant to practice, were expanded. This greatly facilitates the mix design of concrete with particularly low clinker contents, which in this work were illustrated with a blended cement containing only 50% clinker.
