A Comparative Study and Component Analysis of Query Plan Representation Techniques in ML4DB Studies
Authors: Zhao Yue , Li Zhaodonghui , Cong Gao 
Published: March 2024

Query plan is widely used as input in machine learning for databases (ML4DB) research, with query plan representation as a critical step. However, existing studies typically focus on one task, and propose a novel design to represent query plans along with a ML4DB framework, without comparing with other representation methods designed for a different task. This raises a critical question: How do we select a query plan representation method in a ML4DB system?
To address this question, we perform a comparative study on ten representation methods on three distinct ML4DB tasks: cost estimation, index selection and query optimization. Our extensive experiments not only verify the interchangeability of representation methods across different tasks, but also identify consistently high-performing models. Further, we dissect the query plan representation into two core components: feature encoding and tree model, and evaluate the impact of design choices for each in different scenarios. Our results show that the findings for tasks optimizing absolute errors are different from findings for tasks optimizing relative errors. Some findings challenge widely-held assumptions, i.e., one finding shows that tree models do not significantly impact cost estimation results, but only play a significant role to optimize relative performance. Practical guidelines and future directions are provided based on the findings of the study.

Abstract

Dysphania ambrosioides (L.) holds a prominent place in Moroccan folk medicine due to its therapeutic attributes. Despite its widespread use, instances of inadvertent intoxication linked to its consumption have been reported. This study aims to evaluate the potential cytogenotoxic effects of D. ambrosioides leaf aqueous extract (DAAE) and explore the prospective protective role of vitamin C (l-ascorbic acid) through the micronucleus test conducted on (1) Vicia faba root-tip meristem and (2) mouse bone marrow cells. In addition, antioxidant enzyme activities, specifically superoxide dismutase (SOD) and catalase (CAT), were evaluated in V. faba treated with DAAE. After a 7-day daily administration of DAAE to mice, serum biochemical parameters (aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, creatinine, and uric acid) were measured, and histological examination of liver and kidney tissues was performed. The results indicated that DAAE had dose-dependent cytotoxic and genotoxic effects on both biological models. Furthermore, V. faba treated with DAAE showed significant increases in the activities of SOD and CAT enzymes. Mice treated with DAAE exhibited significant elevations in serum biochemical parameters compared to the control group. Histological examination of liver and kidney tissues revealed hepatic degeneration, glomerular shrinkage, and distinct vacuolated tubular epithelial cells. The cotreatment with vitamin C demonstrated a significant protective effect against DAAE-induced cytogenotoxicity. These findings underscore the importance of vitamin C as a protective agent against oxidative stress and cytogenotoxicity induced by DAAE and recommend its use in any DAAE-based preparation.

Authors: Chaker Rawad , Hajj-Hassan Mira , Ozanne Sacha 
Published: March 2024

Abstract
Continuing education offers healthcare professionals the opportunity to adapt to the many changes in society and to improve their skills and knowledge to provide optimal care for patients. As technology evolves, healthcare workers can benefit from virtual peer-to-peer and mentor interactions with digital technology as a platform for continuing professional development (CPD). Nevertheless, healthcare professionals’ experiences in CPD in online learning settings have not been tackled clearly. The aim of our systematic scoping review is to investigate the effects of distance and hybrid learning settings in continuing education on learning outcomes and perceptions among healthcare professionals. A quantitative literature search was conducted following the preferred reporting items for systematic reviews and meta-analyses scoping research, allowing data collection of healthcare study scores from previous articles tackling the subject. A total of 17 articles met the inclusion criteria and were reviewed. We identified four main categories of learning outcomes: knowledge acquisition, skills and performance, participants’ attitudes toward training, satisfaction, confidence, and self-efficacy. This systematic scoping review highlights that continuing distance education improves health professional learning outcomes. Continuing education in online learning setting allow more learning accessibility for healthcare professionals, as it was found to be a solution for temporal and physical constraints.
Reverse engineering and analysis of microstructure polymer fiber via artificial neural networks: simplifying the design approach
Authors: Rahman Afiquer , Mollah Md. Aslam 
Published: March 2024

Abstract
Microstructure polymer fibers have been extensively researched for their applications in various fields. The design and simulation of these fibers have utilized time-consuming techniques like the finite-difference time-domain and finite element method to facilitate the process. This study proposes an optimal artificial neural network (ANN) for predicting the structural design required to achieve desired optical properties. The ANN model takes various optical properties, including confinement loss, effective index, effective mode area, and wavelengths, as inputs to predict fiber design parameters such as diameter and pitch. To address the challenge of skewed distributions, a data set with a Gaussian-like distribution for confinement loss was generated using a logarithmic transformation method, enabling effective training of machine learning models. Furthermore, the ANN model demonstrates its capability to rapidly predict unknown geometric parameters using only the core mode properties of a polymer fiber, achieving results in a significantly shorter time (3 ms) compared to the trial-and-error approach of finite element method simulation (15 s). The reverse engineering model achieves a mean square error of 3.4877 × 10−06 with five hidden layers. The ANN model not only offers ultrafast calculation speed but also delivers high prediction accuracy, thereby accelerating the design process of optical devices. The differentiation among the prediction result, target, and calculation result provides compelling evidence that the proposed approach is an effective methodology for designing microstructure polymer fibers.

Utilization of health service and associated factors among women in childbearing age in selected internally displaced persons camps, Hargeisa – Somaliland
Authors: Asker Isahaq Mohamoud , Nuh Abdulkadir Mohamed 
Published: March 2024

Abstract

Introduction
Access to and use services in health care are significant to the development of health outcomes in many African countries. In most sub-Saharan countries, the utilization of health care services is very low. Although global strategies have been planned to improve access to high-quality health services, there are still obstacles to attain. Women of childbearing age usually need more health services than other age groups, and they are more likely to experience complications during pregnancy and childbirth, which might result in increased morbidity and mortality.

Objective
The aim of this study is to assess the utilization of health services and associated factors among women of childbearing age in internal displaced person (IDP) camps in Hargeisa, Somaliland.

Methods
A community-based cross-sectional study design was employed among women of childbearing age in the selected IDP camps in Hargeisa. Of eight IDPs in Hargeisa, three were selected by the lottery method. A total of 402 women of childbearing age were selected using a simple random sampling method. Data were collected using an interviewer-administered structured questionnaire.

Results
The overall health service utilization among women of childbearing age in Hargeisa IDPs was found to be 61.5%. The age groups of 23–27 years old and 33–37 years old were five times and three times more likely to utilize health services, respectively (adjusted odds ratio (AOR) 5.2 (confidence interval (Cl): 2.1–13.0)) and (AOR 2.7 (Cl: 1.2–5.9)). Married women had lower odds of utilizing health services than single women. (AOR: 0.23 (0.07–0.73)). The Able reading and writing and primary education women have lower odds of utilizing health services than Secondary and above.

Conclusion
The overall health service utilization among women in childbearing in IDPs in Hargeisa was found to be unsatisfactory. Respondents’ age group, marital status, and educational level were found to be significantly associated with health service utilization among mothers in childbearing in IDPs in Hargeisa Somaliland.

Published: March 2024

Abstract
Polyvinyl alcohol (PVA)-based scaffold fabricated by fused deposition modeling (FDM) shows great potential in cartilage repair field. However, the limited mechanical properties after being swollen by water molecules in the body fluid hinder their applications. Herein, the boric acid is introduced to improve the mechanical behaviors of FDM-printed PVA-based scaffold. The ICP, FTIR, SEM, and swelling behaviors are utilized to explore the influence of boric acid concentration on the materials. The results indicate that the boric acid would form boronic ester-crosslinked PVA (B-PVA) and the density of the crosslink will increase at first then decrease with the boric acid concentration increases. As the concentration of boric acid is 1 %, the densest crosslink point in materials can be obtained. Then the fatigue, relaxation, and creep behaviors tests are carried out, which indicates that the crosslinking will improve the mechanical behaviors of scaffold at a great level. At last, the scaffold shows a good mineralization ability and excellent biocompatibility.
De los derechos humanos a los humanos sin derechos
Authors: Pevida Eduardo Klinger 
Published: March 2024

Resumen
La Declaración Universal de los Derechos Humanos se aprobó en París en 1948, compuesta de 30 artículos en los que se detallan todos los derechos políticos, civiles, sociales, económicos y culturales que deben disfrutar todos los seres humanos y guía de comportamiento de los Estados hacia los mismos. Basados en ellos se aprobaron posteriormente el Pacto Internacional de Derechos Económicos, Sociales y Culturales y el de Derechos Civiles y Políticos, todos dieron origen a la “Carta Internacional de Derechos Humanos” de las Naciones Unidas. Aunque ni la “Declaración” ni la “Carta” conceden prevalencia alguna a un conjunto de derechos sobre los otros, un grupo de países resalta los políticos y civiles sobre el resto con fines geopolíticos, obviando la propia falencia en que incurren en sus propias naciones sobre los derechos sociales, económicos y culturales.
Schwäche ist tödlich – Warum Putin die Ukraine angegriffen hat und wie der Krieg beendet werden muss
Authors: Bugayova Nataliya , Stepanenko Kateryna , Kagan Frederick W. 
Published: March 2024

Zusammenfassung
Der russische Präsident Wladimir Putin ist 2022 nicht in die Ukraine einmarschiert, weil er die NATO fürchtete, sondern weil er diese für schwach hielt. Und weil er nach dem Scheitern seiner Versuche, die Kontrolle über die Ukraine mit anderen Mitteln wiederzuerlangen, die Installation einer prorussischen Regierung in Kyjiw als sicher und einfach einschätzte. Sein Ziel war es nicht, Russland gegen eine nicht existierende Bedrohung zu verteidigen, sondern Russlands Macht auszuweiten, die Staatlichkeit der Ukraine auszulöschen und die NATO zu zerstören – Ziele, die er immer noch verfolgt.
Wie man Russland schlagen kann – Lektionen aus dem Verteidigungskrieg der Ukrainer
Authors: Lange Nico 
Published: March 2024

Zusammenfassung
Der Artikel analysiert die Ursachen für den weitgehend erfolgreichen Widerstand der Ukrainer gegen die russische Aggression. Ein wesentlicher Grund für den Erfolg ist die umfassende Mitwirkung der Bevölkerung am bewaffneten Widerstand gegen die russische Invasion. Wichtig ist auch die Tatsache, dass die Ukraine eine sehr moderne datenbasierte Kampfführung betreibt, bei der Daten aus unterschiedlichen Quellen bezogen und verarbeitet werden, um diese zur Bekämpfung des russischen Militärs einzusetzen. Die ukrainischen Streitkräfte arbeiten zudem oft als dezentralisierte Netzwerke mit viel Führungsverantwortung auf unteren und mittleren Ebenen. Dies hat sich als enormer Vorteil erwiesen. In der Kriegführung hat es sich als sinnvoll herausgestellt, Angriffe auf Logistik, Führungseinrichtungen und Kommunikation des Gegners zu konzentrieren. Eine zentrale Rolle kommt im Ukraine-Krieg Drohnen zu, die massenweise im Einsatz sind. Beachtlich ist auch, dass die Ukrainer große Erfolge mit kleinsten Einheiten im Jagdkampf erzielen konnten. Zudem findet eine Renaissance der Artillerie statt, aber in erweiterter, fortgeschrittener Form. Ein weiterer Baustein des Erfolgs der Ukraine ist die komplexe und redundant strukturierte Logistik vor allem auf Schienen, die stabil auch unter Kriegsbedingungen funktioniert. Die Ukraine hat zudem ein hohes Maß an operativer Sicherheit herstellen können, welches wiederum die Voraussetzung für erfolgreiche Täuschungsoperationen war. Nicht zuletzt bietet die Ukraine ein exzellentes Beispiel dafür, wie man mit den richtigen Methoden und Narrativen den strategischen Informationskrieg gewinnen kann. Der Beitrag gelangt zu dem Schluss, dass die NATO-Militärs sehr viel von der Ukraine lernen können und dass die Erfahrungen des Krieges zur Anpassung ihrer Doktrinen und zu entsprechenden politischen Entscheidungen führen müssen.

Combined knee osteotomy and cartilage procedure for varus knees: friend or foe? A narrative review of the literature
Authors: Mabrouk Ahmed , An Jae-Sung , Kley Kristian , Tapasvi Komal , Tapasvi Sachin , Ollivier Matthieu 
Published: March 2024

Varus knees with associated cartilage pathologies are not uncommon scenarios that present to orthopaedic surgeons.
There is no agreement on the ideal management of varus knees with concomitant cartilage pathology.
Through a literature review, the authors tried to answer three main questions:
On October 2022, OVID MEDLINE, EMBASE, and COCHRANE databases were searched. Clinical studies reporting on clinical, radiologic, or macroscopic cartilage regeneration following either isolated knee osteotomy or concomitant osteotomy and a cartilage procedure were reviewed.
Despite controversies, the literature demonstrated favourable outcomes of combined knee osteotomy and a cartilage procedure in patients with substantial deformity and cartilage defects.
Isolated high tibial osteotomy may induce cartilage regeneration in several scenarios and severities of concomitant malalignment and cartilage defects.
There are recommendations that knee osteotomy should be added to a cartilage procedure when an extra-articular deformity of > 5° is detected.
Some studies report good outcomes for combining a knee osteotomy with cartilage grafting, but they lack a control group of isolated osteotomy.
There is still scarce of evidence on the influence of osteotomies on cartilage regeneration and the outcomes of concomitant osteotomy and different cartilage procedures vs isolated osteotomies.
With advanced statistical evaluation (artificial intelligence, machine learning) of big datasets, more answers and better results will be delivered.

Published: March 2024

In this paper, we present our recent results on the solvability of the Dirichlet problem Reω(z) → φ (ζ) as z → ζ, z∈ D, ζ∈ ∂D, with continuous boundary data φ: ∂D ???? R for degenerate Beltrami equations ωz =µ(z)ω2 + σ(z), |µ(z) ˂ 1 a.e., with sources σ: D → C that belong to the class Lp (D), p ˃ 2, and have compact supports in D. In the case of locally uniform ellipticity of the equations, we formulate, in arbitrary simply connected domains D of the complex plane C a series of eff ective integral criteria of the type of BMO, FMO, Calderon-Zygmund, Lehto and Orlicz on singularities of the equations at the boundary for existence of locally Hölder continuous solutions in the class W1.2loc (D) of the Dirichlet problem with their representation through the so-called generalized analytic functions with sources.
Addressing diversity: An analysis of German curricula for history
Authors: Barsch Sebastian 
Published: March 2024

AbstractThis article analyses the extent to which German history curricula address aspects of diversity. The curricula are analysed in terms of whether they include diagnostic phases to identify students' individual interests. It also examines whether the historical experiences of minorities and the agency of subaltern groups are addressed. The extent to which the curricula abandon a Eurocentric perspective and integrate global historical aspects will also be considered. Methodologically, the curricula of two main school types in all German states were analysed by means of a qualitative content analysis. The focus was on curricula for lower and upper secondary schools. The results show that diversity is usually addressed only from the perspective of established narratives. A national and Eurocentric history continues to dominate the curricula. Only a few curricula explicitly address the diagnosis of students' performance and ideas. Finally, the paper discusses the evolving nature of curricula, influenced by societal needs and growing sensitivity to social diversity. It highlights the need for future research on diversity in teacher education and the practicality of implementing complex concepts such as postcolonial thought in the classroom. More empirical research is needed on current curricula and the teaching of history in different regions and types of school.

Published: March 2024

AbstractLycium barbarum contains a variety of phytochemicals, primarily polysaccharides, and other potent compounds. L. barbarum is a plant that has several uses in contemporary society, including food processing and everyday eating. However, through traditional processing methods the medicinal or edible value of L. barbarum cannot be fully exploited, to further improve the utilisation rate of L. barbarum and enrich the variety of L. barbarum market. The L. barbarum compound beverage, which uses L. barbarum as its primary ingredient, was created through a series of trials, including the creation of tea beverage recipes and research on the most suitable content of stabilisers, flavouring agent formulations and so on. In addition, several validation tests, including those involving hypoglycaemic and lipid-lowering were conducted. The results indicated that 0.1 g mL−1 stabiliser CMC-Na, 0.2 g mL−1 erythritol, 3 g mL−1 citric acid, 8% L. barbarum juice, and 6% chrysanthemum tea cold brew extract were the best combinations for food additive formulations. Additionally, compound beverages have hypoglycemic and lipid-lowering effects. In conclusion, the research and development of L. barbarum compound beverages can not only increase the rate at which L. barbarum is utilised but also offer fresh ideas for the research and development of L. barbarum as they transition from cash crop agricultural products to market-oriented standardised processed products.
Disassembling the gendered archetype of the male jazz impresario in the United States
Authors: McGee Kristin , Leidinger Nora 
Published: March 2024

In the United States, jazz impresarios historically inhabited the quintessential cosmopolitan role of (white) male jazz critic and intrepid discoverer of Black musical creativity. This article explores the once entrenched and yet recently challenged gendered and cultural dynamics surrounding the powerful jazz impresario role in an era transitioning from a local individualized coterie of fans and critics with liberal socio-cultural politics to a more specialized, transnationally networked world of professionalized music agents and institutions. To trace this role, the seminal jazz impresarios John Hammond and George Wein are recollected, uncovering their particular embodied enactment of masculinity within the American jazz presentation and festival world. Through second-wave feminist initiatives, a critical counterpoint to this prominent role is explored, including the efforts of pioneering Black musicians and composers Melba Liston and Mary Lou Williams in the 1960s, the first Women in Jazz Festival programmers Carol Comer and Dianne Gregg during the 1970s and 1980s, and the tireless efforts of record label owner, critic, and concert promoter Rosetta Reitz during the 1980s and 1990s. These contrasting legacies set the stage for new avenues of curatorship and jazz presentation which take into account intersectional obstacles and experiences of both women in jazz as well as women behind the scenes in the American jazz music industry.
