Authors: Salek Md. Abu , Islam Md. Shahidul 
Published: April 2023

The goal of this examine is to model the age-time established prevalence of hepatitis B whilst estimating the impact of vaccination. While stochastic models/time series have been used before to version hepatitis B cases in the absence of know-how on the wide variety of susceptible, this paper proposes to apply a way that fits into the generalized additive version framework. Generalized additive models with penalized regression splines are used to make the most the underlying continuity of each age and time in a bendy nonparametric way. Primarily based on a unique case notification dataset, it's far proven that the implemented immunization programme in Bangladesh ended in a huge lower in incidence for babies in their first year of existence with 82% (79%-84%). Moreover, its miles proved that conditional on an assumed baseline susceptibility percent; a clean force of infection profile can be received from which two local maxima had been determined at ages 9 and 24.
Ser mãe de uma pessoa com transtorno de espectro autista: um estudo sobre representações e estigmas em séries
Authors: Faria Marina Dias 
Published: April 2023

As representações midiáticas podem ser capazes de criar e reforçar estigmas e estereótipos. Tal cenário é ainda mais frequente quando se trata de grupos que são socialmente invisibilizados. Nesta pesquisa o objetivo foi analisar as representações de mães de pessoas com transtorno do espectro autista em séries. Para isso foram analisadas duas séries Atypical e Parenthood, séries de grande alcance e que são apontadas como emblemáticas no que diz respeito à representação de pessoas com transtorno do espectro autista. As análises mostraram que as tramas trazem representações que reforçam que as mães de pessoas com autismo correspondem ao estereótipo de extremamente dedicadas aos filhos, dispostas a abandonar suas vidas pessoais e profissionais e responsáveis por manter a família unida, mesmo quando os pais dizem não conseguir lidar com o diagnóstico.
Historia, identidad y mesianismo en la mitología andina
Authors: Gutierrez Estevez Manuel 
Published: April 2023

El autor realiza un análisis paradigmático de seis versiones de las competiciones entre Inkarrí y Collarrí. Demuestra que el sentido de la competición no está en, la victoria sino en el fundamento del intercambio entre los pueblos encabezados por Inkarrí y Collarí. El intercambio asimétrico, contradictorio en sí mismo, expresado y transmitido a través de una serie de competiciones rituales, constituye el objeto del mito.
Sostiene luego, brevemente y de manera hipotética, que lo fundamental del mito de la derrota de Inkarrí a manos de Españarrí no sería la expresión de una esperanza mesiánica, sino la de una búsqueda de reciprocidad necesariamente asimétrica, entre la cultura tradicional andina y la cultura española.
Alude finalmente a un ritual la carrera de los Tres Reyes Magos, en, San Pablo, Provincia de Canchis, que reune lo que los mitos tenían separado: competiciones de Inkarrí y Collarrí por un lado, combate entre Inkarrí y Españarrí por otro. Los tres reyes -Inkarrí, Collarrí y Mistirey - compiten y en los efectos esperados según cuál de ellos haya sido vencedor -buen o mal año agrícola-- se expresan su complementariedad y reciprocidad.

Published: April 2023

Introducción: Los aneurismas intracraneales representan el 85% de casos de hemorragias subaracnoideas, dentro de las cuales las no traumáticas tienen una alta tasa de mortalidad (40-60%). En el manejo endovascular y microquirúrgico de esta enfermedad, el debate ha sido siempre intenso respecto a si el tratamiento temprano produce un beneficioso resultado funcional y reduce la morbi-mortalidad del paciente. Caso Clínico: Paciente mujer de 54 años, admitida con cefalea súbita y cuadro neurológico que cursó con rápido deterioro. La tomografía mostró hemorragia subaracnoidea por ruptura aneurísmica del complejo comunicante anterior; fue sometida a microcirugía dentro de las primeras 24 horas y transferida luego a UCI, sin complicaciones. Discusión: El tiempo de resolución, sea mediante clipaje microquirúrgico o tratamiento endovascular es tema de intensos debates. Las guías actuales señalan la necesidad del manejo más temprano posible de la patología. Conclusión: En nuestro caso, se obtuvo un buen resultado funcional debido a varios factores uno de ellos el ingreso precoz a cirugía. La actualización de las guías y nuevos estudios ayudarán a mejorar el conocimiento de la enfermedad y protocolos hospitalarios adecuados a la realidad clínica ayudarán a reducir su tiempo de resolución.

Authors: Tat Jimmy , Bodansky David , Sheth Ujash , Ung Yee , Whyne Cari , Nam Diane 
Published: April 2023

Background:
The humerus is the second most common site of metastatic disease involving long bones, yet it is still unclear which patients are at high risk for a fracture and may require prophylactic surgical fixation. The goal of this study was to assess the validity of the Mirels score to predict fractures of metastatic lesions in the humerus.

Methods:
We performed a retrospective electronic chart review of patients with humeral metastases at our institution (2005 to 2021), with 188 patients meeting the inclusion criteria. Sixty-one of the patients developed a fracture during follow-up. The metastatic humeral lesions were scored according to the Mirels rating system and additional radiographic criteria (cortical breach, location within the humerus, number of lesions). The predictive value of each Mirels score cutoff for fracture was assessed using sensitivity, specificity, area under the receiver operating characteristic curve (AUC), and multivariate logistic regression. Survivorship until fracture was analyzed for each Mirels score cutoff using Kaplan-Meier curves and the log-rank test. Significance was set at p < 0.01.

Results:
There were no significant differences in age, sex, side of the lesion, type of malignancy, and radiation dose between the groups with and without fracture (all p > 0.01). A Mirels score of ≥8 points had the best predictive profile, with sensitivity of 83.6%, specificity of 79.5%, and AUC of 0.82 (95% confidence interval [CI], 0.75 to 0.88, p < 0.01). A logistic regression model also demonstrated that a Mirels score of ≥8 (odds ratio = 5.8, 95% CI = 1.9 to 18.2, p < 0.01) and a cortical breach (odds ratio = 21.0, 95% CI = 5.7 to 77.2, p < 0.01) were significant predictors of pathological fracture. No other radiographic characteristics were found to be significant predictors of fracture.

Conclusions:
This study indicated that a Mirels score of ≥8 points had the best predictive profile for anticipating fractures at a metastasis in the humerus. This is in contrast to the traditional Mirels definition of an impending pathological fracture that is used for the lower extremity, a score of ≥9. Additionally, the presence of a cortical breach was a significant predictor of fracture risk.

Level of Evidence:
Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

Authors: Muharni Riza , Sutra Dewi Aminar 
Published: April 2023

Titanium paduan merupakan material implan yang banyak digunakan untuk implan medis terutama bidang kedokteran gigi ( ortodentik ). Aplikasi implan gigi pada rongga mulut mengalami fluktuasi temperatur sesuai dengan temperatur makanan dan minuman yang masuk kedalam mulut sehingga membuat implan mudah terkorosi. Pada penelitian ini dilakukan pelapisan biokeramik hidroksiapatit pada permukaan Ti6Al4V ELI dengan metode EPD kemudian direndam dengan larutan air ludah buatan selama 6 minggu pada temperatur yang berfluktuasi yaitu 20ºC dan 60ºC. Tujuan dari penelitian ini adalah mengetahui pengaruh temperatur fluktuasi dalam air ludah buatan terhadap laju korosi dari Ti6Al4V ELI yang dilapisi biokeramik dengan metode weight loss ( kehilangan berat ) dan mengetahui pengaruh temperatur fluktuasi dalam air ludah buatan terhadap nilai kekerasan dari Ti6Al4V ELI yang dilapisi biokeramik.Hasilnya laju korosi menurun dari 1,10 mpy menjadi 0,43 mpy dan nilai kekerasan menurun dari 317 HVN menjadi 200 HVN. Hal ini menunjukkan bahwa hidroksiapatit dapat menghambat korosi tetapi tidak dapat mempertahankan sifat mekanis dari implan.

Abstract
The emergence of new viral threats, wide applications of viruses in biotechnology and challenges associated with viral contamination necessitate multiple types of virustatic agents. Here, we show that highly biocompatible tapered CuS nanoparticles efficiently agglutinate COVID virus with binding affinity dependent on chirality of surface ligands and particle shape. L-penicillamine-stabilized nanoparticles with left-handed curved apexes display half-maximal inhibitory concentration as low as 0.57 pM for authentic SARS-CoV-2 viruses, which is ca 15 times greater than for antibodies. Exposure to elevated temperatures causes no change in activity or biocompatibility of nanoparticles while completely deactivating antibodies. Testing with mice indicates that the chirality-optimized nanoparticles can serve as analogs of high antiviral molecular weight biologics complementing the current spectrum of virustatic agents. Their thermal and chemical stability simplifies their applications in biomedical and biotechnological processes.

Published: April 2023

AbstractHow to effectively recycle Ni–Co ore mining mullock (OMM) is a key means to address both local environmental pollution and resource waste. In this study, OMM and bottom ash (BA) were prepared into cementitious materials (OBM) by mechanochemical means with gentle conditions. It is mainly realized by grinding the mixture and pressing it into columnar blocks. The results show that the maximum compressive strength of OBM is 4.803 MPa in 28 day meet the standard of China mine backfilling for mine repair, and the stability efficiency of Ni2+and Co2+is above 90%. The mechanism studies show that the amorphous materials recombine to form silicon-aluminum polymers, while a small portion of Ni2+and Co2+binds to the polymer during consolidation to form massive structure. Most of the heavy metal ions are encased in the hard structure, which is relatively stable and without pollution risk. The chemical behavior of metals in the system is fitted by geochemical model. This study not only solved the problem of heavy metal contamination in OMM, but also transformed it into a cementitious material that can be used for backfilling of local pits.

Published: April 2023

Abstract
Background Blastocyst transfer may cause cycle cancellation due to no blastocyst has developed. Could we develop a model for predicting probability of blastocyst formation on Day 5?Methods The model was developed base on 4327 fresh in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) cycles. Univariate logistic regression analysis and multivariate logistic regression analysis were conduct to investigate the relationship between patient and cycle characteristics and the formation of usable blastocysts on Day 5. And the nomogram was developed based on variables selected from multivariate logistic regression analysis. Discrimination and calibration of the model was evaluated by area under the curve (AUC) of the receiver operating characteristic (ROC) curve and calibration curve.Results Female age, type of fertilization, fertilization rate, cleavage rate, number of Day 3 embryo extended culture to blastocyst stage, high-quality rate of Day 3 embryos extended culture to blastocyst stage, were predictors of usable blastocysts formation on Day 5. Results showed AUC in the training cohort was 0.874 (95% CI 0.862–0.887) and AUC in validation cohort was 0.886 (95% CI 0.867–0.905), indicating the good discrimination ability of the model. And the calibration curves in training and validation cohorts were both close to the ideal diagonal line, reflecting good accuracy of the model.Conclusion This model provides an intuitive and simple tool for predicting the probability of usable blastocysts formation on Day 5, and it may be helpful to reduce the cancellation rate of blastocyst transfer.
Accelerating Thouless pump in bilayer integrated waveguide lattices

Published: April 2023

Abstract
The Thouless pump refers to the quantized transport of a one-dimensional system under cyclic motion of the system parameters without external forces. This phenomenon has a first Chern class topological invariant and typically requires a slow evolution to meet the adiabatic condition, which imposes a constraint on the system's compactness. In this study, we propose a method to accelerate the Thouless pump in an optical system that consists of bilayer integrated silicon waveguides operating at telecommunication wavelengths. The bilayer system's effective long-range couplings allow the adiabatic criteria to persist even with a rapid parameter evolution speed. As a result, the adiabatic pump evolution can be significantly sped up without violating the topological nature. This approach challenges traditional notions and promises a feasible and powerful compact platform for quasi-3D photonic integration at the nanoscale, enabling the realization of complex topological physics and novel on-chip photonic devices.
Finite-time control for UA quadcopter in application of wildfire monitoring
Authors: Mawanza Joewell Tafadzwa 
Published: April 2023

Abstract
An improved finite-time control technique for an uncrewed aerial (UA) quadcopter subjected to nonlinear uncertainties and disturbances is proposed in this paper. Firstly, high order sliding mode observer (HOSOM) is developed to estimate system states, nonlinear uncertainties and disturbances in the system. The estimated system states are then used to design an improved non-singular fast terminal sliding mode control scheme with an improved exponential term added to the sliding surface. The overall system stability under the proposed control scheme is investigated using the Lyapunov stability theory. Finally, numerical simulations show that the proposed control scheme offers a comprehensive solution to the trajectory tracking problem for a UA quadcopter.

Published: April 2023

Abstract
Heavy-duty freight railway axles are no less important than that of passenger ones, due to the potentially catastrophic results caused by the derailment of trains carrying hazardous substances. Intrinsic and extrinsic imperfections challenge classical design theories built based on the safe life concept, and damage tolerance assessment becomes vital for the safety and reliability of long-term serviced railway axles, as pits and scratches are common defects for heavy-duty railway axles. In this work, four-point rotating bending fatigue tests of the AAR-CM railway axle steel specimens with semi-circular and circumferential groove notches were conducted. The fatigue limit of the semi-circular notched specimen was evaluated based on the fracture mechanics theory, in which non-conservative results were obtained by the Haddad model; and the 𝑺–𝑵curves of circumferential groove notched specimens were correlated by the theory of critical distance (TCD).

Abstract
Background The Canadian 24-hour movement behavior (24-HMB) guidelines recommend an adequate level of physical activity (PA), a limited amount of screen time (ST), and sufficient sleep duration (SLP) to promote the healthy development of children. Although the positive effects of adhering to the 24-HMB guidelines have been established for several health parameters, less is known about how adherence to the 24-HMB guidelines relates myopia risk (i.e., inability to see distant objects properly). This study investigated associations between meeting 24-HMB guidelines and myopia risk in school-aged children.Method Using a questionnaire survey, this cross-sectional study was conducted among parents of school-aged children (5–13 years) in China from September 15 to October 15, 2022, with a total of 1,423 respondents with complete data for analysis. Parents reported their child’s time spent in moderate-to-vigorous physical activity (MVPA), SLP and ST. Multiple logistic regression analyses were performed to examine the associations between measures of PA, ST, and SLP alone and in combination, and myopia.Results A relatively low percentage of the children (4.92%) met all 24-HMB guidelines, while 32.46% had myopia. Girls had a significantly higher risk of myopia compared to boys (OR = 1.3, 1.002 to 1.68, p = 0.049). Children of parents without myopia had a lower risk of myopia (OR = 0.45, 0.34–0.59, p < 0.001). Children who lived in cities (OR = 1.83, 95% CI 1.33 to 2.52, p < 0.001) or towns (OR = 1.60, 1.03 to 2.47, p = 0.04) had a significantly higher risk of myopia compared to those living in villiages. Meeting SLP guidelines (OR = 0.50, 95% CI 0.31 to 0.82, p < 0.01), meeting ST + SLP guidelines (OR = 0.47, 95% CI 0.32–0.69, < 0.001), and meeting all three guidelines were associated with significantly decreased risk of myopia (OR = 0. 40, 95% CI 0.20–0.82, p = 0.01). Meeting more 24-HMB guidelines was associated with reduced risk of myopia.Conclusions Adhering to SLP guideline, ST + SLP guideines, and ST + SLP + PA may be a preventive approach to the onset and progression of myopia. Future research investigating dose-response associations, and potential mechanisms, is necessary to achieve a more nuanced understanding of the observed associations.

Published: April 2023

Abstract
Now deep learn-based object detection can be deployed on drones for criminalinvestigation or military counter-terrorism. Because the proportion of pixels of pedestrians orvehicles in the aerial picture taken by UAV is very small, the probability of detection of smallobjects in the distance is very low or there are omissions. In this paper, the HPS-YOLOv7 algorithmis proposed to improve the detection accuracy of small objects. We have proposed a modifiedhigh-efficiency layer aggregation network for feature extraction, solved the problem that theconvergence of depth models tends to worsen, and lightly processed models with a Bottleneckstructure. We have proposed C-recursively gated convolution, which fully fuses shallow objectsemantic information and enhances the model capacity. To be more helpful for detect small objects,the detection head of 20×20 was replaced by 160×160 detection head, and shallow feature fusionnetwork (SFN) was connected to make up for the information lost by small objects in the deepconvolutional network. Mosaic data enhancement and a priori anchor adaptive adjustment strategyare used in model training to improve the detection efficiency and accuracy. Experimentalevaluation was carried out on VisDrone2019 and Tinyperson data sets respectively. The results showthat mAP increases by 3.0% and 13.29% compared with yolov7 on the basis of IoU=0.5. mAP of0.5≤IoU≤0.95 increased by 1.8% and 3.97%; It is shown that the advantages of HPS-YOLOv7 insmall object detection have certain theoretical value and practical significance.
Fixed-Time Tracking Control for State-Constrained Nonstrict-Feedback Systems Without Feasibility Conditions

Published: April 2023

Abstract
This paper investigates the fixed-time tracking control schemes for a class of state-constrained nonstrict-feedback nonlinear systems without involving the feasibility conditions. Based on nonlinear mapping, a nonlinear state transformation function is constructed to convert the constrained system into an equivalent system without state constraints, which achieves the asymmetric time-varying state constraints and eliminates the feasibility conditions on the virtual controllers. A nonlinear fixed-time filter with dynamic surface control is utilized to handle the problem of explosion of complexity in the backstepping framework. Furthermore, we develop a fixed-time observer-based tracking control strategy for the nonstrict-feedback system subject to unmeasured states. To remove the restrictive assumptions of known control gain functions, the nonlinear system is reconstructed and the neural networks are employed to approximate the unknown terms. In addition, a hyperbolic tangent function is utilized to address the input saturation problem. Through the Lyapunov theorem, the closed-loop system is proven to be practical fixed-time stable within the constraint requirements. Finally, simulation results demonstrate the effectiveness of the proposed methods.
