Introduction:
Initiation of Pavlik harness treatment for developmental dysplasia of the hip (DDH) by 6 to 7 weeks of age predicts a higher rate of success. Child Opportunity Index (COI) 2.0 is a single metric designed to measure resources and conditions affecting children's healthy development. This study investigates COI in relation to the timing of DDH diagnosis.

Methods:
This is a retrospective cohort study on patients younger than 4 years diagnosed with DDH between 2016 and 2023, treated with a Pavlik harness, rigid hip abduction orthosis, and/or surgery. Demographic and clinical data were recorded, including date of first diagnostic imaging. Patients with syndromes, congenital anomalies, or neuromuscular disorders and those referred with an unknown date of first diagnostic imaging were excluded. A subgroup analysis of patients diagnosed at ≤6 weeks (“early”) and >6 weeks (“late”) was conducted. Statewide COI scores (total, three domains) and categorical quintile scores (very low, low, moderate, high, and very high) were recorded.

Results:
A total of 115 patients were included: 90 female infants (78%), with a median age of 32 days at diagnostic imaging. No notable difference was observed between median age at diagnosis for study patients in low or very low quintiles and those in moderate, high, or very high quintiles for COI total or domains. “Early” and “late” diagnosis subgroups did not differ markedly by COI total or domains, nor insurance type, race, or ethnicity. Subgroups differed markedly by race and insurance status.

Discussion:
In an urban children's hospital, COI did not differ markedly between patients diagnosed with DDH by ≤6 weeks and >6 weeks. This is the first study to pose this question on DDH in a population with predominantly low/very low COI scores and public insurance, which may lead to unexpected results. Replicating the study in a different setting could yield different results.

Maniculan

The Manicule. Literature’s Guiding HandThe ☛ manicule ☚ or typographical pointer has a unique place in literary history. Originally a reader’s annotation, it became a printer’s mark and an advertiser’s tool-in-trade before making the leap into narrative as a fictional object in its own right. In this essay I trace the manicule’s evolution from the medieval scriptorium to electronic publishing in the late age of print before examining its narrative and aesthetic functions in V. F. Palmblad’s Törnrosens Bok (1840), August Strindberg’s Röda rummet (1879), and Hjalmar Söderberg’s Doktor Glas (1905). In this trio of novels, I argue, the manicule is not just another element of narrative realism but a way to thematize historic changes in the material conditions of literary production. More than visual gimmicks, these pointing hands invite us to reassess the wider significance of these landmark works of Swedish literature.

A study on the correlation between English learning styles and learning strategies of junior middle school students
Authors: He Ruitang 
Published: June 2024

Abstract: Researches show that learning style and learning strategy are two very important factors that affect English learning, and their mutual influence plays a role in language learning. Based On Reid's theory of perceptual learning styles and Oxford's theory of language learning strategies, this study uses the questionnaire of perceptual learning styles and language learning strategies to investigate 99 students from two classes of the second grade of a key middle school in Changchun, and interviews 12 of them.This paper explores the correlation between English learning styles and English learning strategies of junior high school students by using quantitative and qualitative methods. The results are as follows: (1) The general characteristics of junior high school students' English learning styles are that they have a variety of secondary learning styles, and only the visual style is their main learning style. (2) Junior high school students are not good at using English learning strategies, their utilization rate is low, and they lack frequently used learning strategies. (3) There are certain correlations between English learning styles and learning strategies of junior high school students, and they are all positive, but most of them are low. According to the results of the study, some suggestions are put forward for teachers and students.
De juridische emancipatie van slachtoffers van criminaliteit

The legal emancipation of crime victims: A systematic and critical literature review of historical explanations
The legal position of crime victims has been greatly extended in the Netherlands in the last decades, particularly within criminal proceedings. Victims have been granted a number of rights within these proceedings. Well known are the right to file a compensation claim and the right to deliver a victim statement. This legal ‘emancipation’ is rather remarkable in light of the distrustful attitude the Dutch legislator for a long time has had towards victims. The aim of this study was to explore which factors may explain this turnaround. This was done through a systematic and critical review of the literature. In 4 Dutch databases (BJu tijdschriften online, Kluwer navigator, Legal Intelligence en Sdu OpMaat) we searched for relevant publications. To ensure that no other relevant publications were missed, we screened the reference lists of these publications and their authors’ publications lists and entered their titles in Google Scholar to check for relevant citing and related publications. Eventually, twenty-seven publications were included in the literature review. These publications provided 10 different explanations for the legal emancipation of crime victims. However, the large majority of these explanations were not based on historical research and may therefore be unreliable and invalid. More research is needed to confirm or refute the role these factors played in the extension of victims’ legal position.

A Comprehensive Investigation of Brushless Direct Current (BLDC) Motors: Current State, Advanced Control Strategies, and Utilization Systems
Authors: Akram Suhair , Aljanabi Mohanned 
Published: June 2024

In the field of dynamic applications, specifically within automotive, pumping, and rolling sectors, there exists a noteworthy preference for the use of Brushless Direct Current (BLDC) motors. Projections show that, by the year 2030, BLDC motors are poised to supersede classic induction motors as the dominating force in industrial power transmission. This transformation, however, is accompanied by crucial issues and unresolved research challenges in the environment of BLDC motors.
The core concern revolves around the dependability and endurance of BLDC motors. These motors presently encounter obstacles in achieving advanced fault tolerance, reduced electromagnetic interference, lowered acoustic noise, as well as mitigated flux and torque fluctuations. The path of closed-loop vector control emerges as a possible technique to address these challenges.
In recent literature studies spanning the previous five years, a striking scarcity of exploration in the domain of BLDC motor controllers and design becomes clear. Furthermore, key areas such as the comparative study of existing vector control schemes, the increase of fault tolerance control, the attenuation of electromagnetic interference inside BLDC motor controllers, and other pivotal elements remain undiscovered. These research lacunae serve as a motivator for the undertaking of an intensive investigation to face the fundamental issues related with BLDC motors. BLDC motors have quickly become the motor of choice for electric vehicle (EV) applications due to the fact that they are reliable, simple, and energy efficient.
This detailed survey goes deep into numerous sophisticated control strategies for BLDC motors. These encompass fault tolerance control, electromagnetic interference reduction, field orientation control (FOC), direct torque control (DTC), current shaping, input voltage control, intelligent control, drive-inverter topology, and the underlying operational principles aimed at the minimization of torque irregularities. Additionally, the study goes through the historical narrative of BLDC motors, the categorization of BLDC motor kinds, their structural complexity, mathematical modeling, and the standards that govern BLDC motor uses in varied industries
The Generalized Gompertz-G Family of Distributions: Statistical Properties and Applications

Published: June 2024

This research aimed at presenting a new statistical model called the Generalized Gompertz-G family of distribution via the method of Alzaatreh, which introduces additional shape parameters for any baseline distribution. We investigate various mathematical aspects of this model, explicitly deriving properties such as moments, moment-generating function, survival function, hazard function, entropies, quantile function, and order statistics distribution. We explore a particular member of this family of distributions, the Generalized Gompertz-Exponential Distribution (GGED), by defining its properties and doing a detailed analysis. A Monte Carlo simulation was utilized to evaluate the model's flexibility and performance, and the distribution family's potential utility in real-world data analysis was further highlighted by investigating the model's parameter estimation using the method of maximum likelihood. We also assess the adaptability of the Generalized Gompertz-Exponential distribution using a real-life dataset and relating its performance with other established models through information criterion. The results show that the Generalized Gompertz-Exponential distribution (GGED) outperformed the compared distributions, emphasizing its potential applicability in diverse practical scenarios for data modeling.

Authors: Akinbolati A , Adamu Idris , Adache Tunde Davide 
Published: June 2024

This research investigated the variation of Surface Radio Refractivity and its propagation effects on radio signals over Lokoja, Kogi State, Nigeria. The study used six years (2015-2020) of satellite data on temperature, pressure, relative humidity and rainfall at the surface (12 km) above ground level. The data retrieved were used to determine the monthly, seasonal, and annual Surface Radio Refractivity value for Lokoja Kogi State. Results show that high Surface Radio Refractivity values were recorded generally during the wet season months compared to the dry season months in all Six years (2015-2020). The average values of Surface Radio Refractivity 307.7407 (N-units) and 323.4674 (N-units) were obtained during the dry and wet season, respectively. The minimum surface radio refractivity values of 280.7245, 284.6583, 308.0021, 285.2304, 304.2521 and 285.9139 (N-units) were recorded for the years 2015, 2016, 2017, 2018, 2019, and 2020 respectively. On the other hand, the highest values of 330.8153, 331.8133, 330.3580, 330.9278, 332.4704, and 331.1316 (N-units) were recorded for the years 2015, 2016, 2017, 2018, 2019 and 2020, respectively. Higher values of Surface Radio Refractivity were recorded generally during the wet season compared to the dry season months in all years (2015-2020) in Lokoja, Kogi State. This implies higher radio signal attenuation due to Ns during the wet season compared to the dry season. The correlation coefficients between Surface Radio Refractivity Ns and temperature are -0.41, -0.51, -0.49, -0.48, -0.46, -0.50, pressure 0.07, -0.15, -0.28, -0.08, -0.11, -0.26, relative humidity 0.89, 0.84, 0.75, 0.84, 0.77, 0.83, and the amount of rainfall 0.76, 0.64, 0.73, 0.58, 0.51, 0.65 respectively in the year 2015, 2016, 2017, 2018, 2019, 2020. The overall findings of the work will be useful to radio engineers for properly planning a reliable power budget for terrestrial radio communication over Lokoja, Kogi State.
A DFT+U Study of the Structural and Electronic Properties of Zinc Doped Anatase TiO2 Nanomaterial
Authors: Alhassan Shamsuddeen Sani , Abdulsalam Mahmud 
Published: June 2024

This work reports a theoretical study on the structural and electronic properties of the anatase phase of titanium dioxide (TiO2) within the framework of density functional theory corrected for on-site coulomb interactions in strongly correlated materials (DFT+U). The exchange correlation was described by local density approximation (LDA). The optimized lattice parameters obtained for the pure anatase TiO2 agree with the experimental data. Our results revealed that, after the zinc doping, the structure didn't change but there was a little expansion in the volume of the pure material. It was found that the doped structure's stability increases as the concentration of the dopant increases, but all the doped structures are stable. However, introducing the zinc dopant has significantly reduced the band gap of the pure anatase by 80.7 %, 80 %, and 78.6 % due to 0.25, 0.5, and 0.75 doping concentrations, respectively. This implies that the band gap energy increases as the doping concentration increases.
