Interference Mitigation and Dynamic User Association for Load Balancing in Heterogeneous Networks
Authors: Hassan Noha , Fernando Xavier 
Published: November 2022

<p>Viewing the communication system as three-dimensional (3-D) with various tiers cooperating among each other is a new trend to present 5G heterogeneous networks (HetNets). Base stations (BS) in each tier operate with different power levels, access methods, and unique topologies. A proper user (UE) association algorithm for HetNets is a great challenge. We develop a new real-time dynamic user (UE) association algorithm for multitier cooperating systems that considers users' mobility and traffic dynamics considering both overall network load and received signal to interference and noise ratio (SINR). Despite that our proposed UE association algorithm does not depend on an interference mitigation algorithm to improve its performance, we develop a location-based interference mitigation algorithm to mitigate co-tier and cross-tier interferences in the worst case scenario of spectrum sharing among various tier BSs to overcome some of the drawbacks of spectrum partitioning algorithms. Our new algorithms are studied and analyzed through simulation and they are proved to provide the best performance compared to other algorithms.</p>

Authors: Escayg Kerry-Ann , Berman Rachel , Royer Natalie 
Published: November 2022

<p> </p>
<p>Psychological research on Canadian children and race has shown that young White and racialized children generally have a pro-White bias. While scholars have utilized developmental or social psychological explanations for this finding, none have used an antiracism lens to interpret children’s racial attitudes or to develop an antiracism pedagogy. To address this research gap, this article uses antiracism theory as an analytical tool to explore the social-historical processes that have affected how children evaluate racial differences and White identity. It also briefly proposes antiracism teaching practices specific to early childhood education settings. </p>

Published: November 2022

Evaluation of learning is a crucial step in understanding the progress of students' competence and determining the success of the learning process. This study aims to explain, with reference to the 2013 Curriculum, the experience of teachers conducting evaluations during online learning. This study focused on nine English teachers from nine public schools in Jambi City, including five junior high schools, two high schools, and two vocational high schools. This case study employed an interview instrument which data were then qualitatively analyzed. The findings of this study include teachers' comprehension of learning evaluation, forms of assessment, barriers in the learning process, and the effectiveness of implementing learning evaluation. First, teachers have a comprehensive understanding of learning evaluation, which includes students’ knowledge, skills, and attitudes. However, teachers consider the number of student competencies that must be assessed in online learning to be burdensome, specifically due to limited hour of meeting. The teachers emphasize on delivering the material and decrease the number of competencies that students must acquire. Second, teachers assign daily tasks to assess students' knowledge, video projects to assess their skills, and pay attention to the punctuality of assignment submission and classroom interaction to assess students' attitudes. Third, the obstacles of learning include the absence of gadgets, limited of internet quotas, the difficulty of the internet access, the lack of student participation, and the absence of parental support for online learning. Fourth, the limited abilities of teachers, the difficult conditions of students, and the limited time contribute to the ineffectiveness of the online learning process. In conclusion, the evaluation of online learning cannot completely reference the curriculum.

Políticas educativas, planes de estudio y diferencias sexuales bajo un enfoque de género (1884-2007)
Authors: Casabona Guido 
Published: November 2022

El presente escrito aborda la articulación entre planes de estudio y diferencias sexuales bajo un enfoque de género en el contexto histórico de la política educativa Argentina. Considerando un rango temporal de larga duración que va desde la sanción de la Ley N.° 1420 de Educación Común en 1884, hasta el año 2006 con el dictado de la Ley N.° 26206 de Educación Nacional (LEN); este trabajo recorre lo que se concibe como sexualidad en los planes de estudio y cómo se expresa en las políticas educativas lo que se ha esperado para cada persona en base a su sexualidad y género.
El análisis realizado ha sido estructurado en dos apartados. El primero presenta una periodización articulada en cuatro instancias denominadas: Sexualidad sexuada (1884-1945), Sexualidad como igualdad (1945-1955) Sexualidad reprimida (1955-1994) y Sexualidad como derecho (2000-2007). Se trata de un eje que explica las características centrales de cada etapa a la luz de las diferencias sexuales y de género en los planes de estudio, en un ejercicio que conecta la denominación de cada instancia, con cuestiones significativas de los cuatro momentos abordados. El segundo apartado se encuentra dedicado a indagar discursos pedagógicos y políticas educativas, a través del análisis de planes de estudio vigentes en cada una de las cuatro etapas mencionadas, dando cuenta de continuidades y rupturas entre ellas. El estudio cierra con las conclusiones, a modo de reflexiones finales en torno al recorrido realizado.

Published: November 2022

A previous study found that the capacitive behavior of nanoparticles fed to the silkworm can be delivered to carbonized silk fibers, which can be used to fabricate electrodes for the construction of flexible supercapacitors. However, the tendency of nanoparticles to aggregate decreases the quantity of nanoparticles that enter the silk and therefore reduces the capacitance performance of the prepared carbonized silk. Here, we sprayed ammonium molybdate tetrahydrate (AMT) on the surface of mulberry leaves used for feeding silkworms and investigated the effect of feeding AMT on the growth of silkworms and the properties of spun silk. The precursor incorporated into the silk was converted into scattered MoO2 NPs, which were embedded within the carbonized silk fiber (CSF) via carbothermal reduction. The specific capacitance of CSF obtained from silkworms fed with an aqueous solution of AMT-treated mulberry leaves reached up to 298 F/g at 0.2 g/A, which is much higher than that of the control group (102 F/g). Since AMT is highly water-soluble, and its concentration can be easily modulated, we believe that the proposed strategy is feasible for the large-scale fabrication of CSF with enhanced capacitive performance.

BackgroundMyocardial infarction induces elevation of progenitor cells in the circulation, a reparative response inhibited by type-2 diabetes.ObjectivesDetermine if myocardial infarct severity and diabetes interactively influence the migratory activity of CD34+/CXCR4+ progenitor cells and if the migratory test predicts cardiac outcomes.Materials and methodsA longitudinal study was conducted on patients with or without diabetes with a STEMI or NSTEMI. CD34+/CXCR4+ cells were measured in the peripheral blood using flow cytometry, and migratory activity was tested in vitro on cells isolated from samples collected on days 0 and 4 post-infarct. Cardiac function was assessed at three months using cardiac MRI.ResultsOf 1,149 patients screened, 71 (6.3%) were eligible and consented. Fifty had STEMI (16 with diabetes) and 21 NSTEMI (8 with diabetes). The proportion of CD34+/CXCR4+ cells within blood mononuclear cells was 1.96 times higher after STEMI compared with NSTEMI (GMR = 1.96, 95% CI 0.87, 4.37) and 1.55 times higher in patients with diabetes compared to patients without diabetes (GMR = 1.55, 95% CI 0.77, 3.13). In the latter, STEMI was associated with a 2.42-times higher proportion of migrated CD34 + /CXCR4 + cells compared with NSTEMI (GMR = 2.42, 95% CI 0.66, 8.81). In patients with diabetes, the association was the opposite, with a 55% reduction in the proportion of migrated CD34+/CXCR4+ cells. No statistically significant associations were observed between the frequency in peripheral blood or in vitro migration capacity of CD34+/CXCR4+ cells and MRI outcomes.ConclusionWe document the interaction between infarct and diabetes on the migratory activity of CD34+/CXCR4+ cells. The test did not predict functional outcomes in the studied cohort.

Published: November 2022

IntroductionMasticatory function is often impaired in patients with painful temporomandibular disorders (TMD); therefore, more detailed studies on comminution and mixing ability are warranted in well-defined TMD patients with chronic myalgia. Moreover, there is a need to explore the correlation between any changes in perceived pain or fatigue in such patients and the masticatory function.Materials and methodsSelf-assessments using questionnaires regarding pain, oral health, jaw function, masticatory ability, fear of movement, and psychosocial signs were answered by all the participants. A series of chewing tasks involving viscoelastic food and two-colored gum were performed. Optical imaging and analysis were conducted. Bite force as well as characteristics of pain and fatigue were assessed.ResultsIn patients, the fragmented soft candy particles were less in number and had larger median of area and minimum Feret's diameter after standardized chewing compared to healthy individuals (P = 0.02). Surprisingly, the two-colored Hue-Check gum was less mixed by the healthy controls since they displayed a greater variance of the hue (P = 0.04). There were significant differences between the patients and the healthy controls in the self-assessed masticatory ability, mainly regarding pain-related variables.ConclusionsObjectively, TMD patients with chronic myalgia exhibited an impaired masticatory performance with less efficiency in comminuting soft viscoelastic food compared to the pain-free healthy control group. There was an agreement between the patients' self-assessed masticatory ability and the efficiency of their masticatory function.

ObjectiveFetal macrosomia is defined as a birth weight more than 4,000 g and is associated with maternal and fetal complications. This early metabolic disease may influence the entire life of the infant. Currently, macrosomia is predicted by using the estimated fetal weight (EFW). However, the EFW is inaccurate when the gestational week is gradually increasing. To assess precisely the risk of macrosomia, we developed a new predictive model to estimate the risk of macrosomia.MethodsWe continuously collected data on 655 subjects who attended regular antenatal visits and delivered at the Second Hospital of Hebei Medical University (Shijiazhuang, China) from November 2020 to September 2021. A total of 17 maternal features and 2 fetal ultrasonographic features were included at late-term pregnancy. The 655 subjects were divided into a model training set and an internal validation set. Then, 450 pregnant women were recruited from Handan Central Hospital (Handan, China) from November 2021 to March 2022 as the external validation set. The least absolute shrinkage and selection operator method was used to select the most appropriate predictive features and optimize them via 10-fold cross-validation. The multivariate logistical regressions were used to build the predictive model. Receiver operating characteristic (ROC) curves, C-indices, and calibration plots were obtained to assess model discrimination and accuracy. The model’s clinical utility was evaluated via decision curve analysis (DCA).ResultsFour predictors were finally included to develop this new model: prepregnancy obesity (prepregnancy body mass index ≥ 30 kg/m2), hypertriglyceridemia, gestational diabetes mellitus, and fetal abdominal circumference. This model afforded moderate predictive power [area under the ROC curve 0.788 (95% confidence interval [CI] 0.736, 0.840) for the training set, 0.819 (95% CI 0.744,0.894) for the internal validation set, and 0.773 (95% CI 0.713,0.833) for the external validation set]. On DCA, the model evidenced a good fit with, and positive net benefits for, both the internal and external validation sets.ConclusionsWe developed a predictive model for macrosomia and performed external validation in other regions to further prove the discrimination and accuracy of this predictive model. This novel model will aid clinicians in easily identifying those at high risk of macrosomia and assist obstetricians to plan accordingly.

Published: November 2022

IntroductionChronic and acute chlorogenic acid (CGA) can improve glucose tolerance (GT) and insulin sensitivity (IS). However, whether acute administration of CGA has beneficial effects on hepatic lipid metabolism and cecal microbiota composition remains unclear.MethodsIn the current study, diabetic db/db mice were administered CGA or metformin, and db/m mice were used as controls to explore the effects of CGA on hepatic lipid metabolism, including fatty acid oxidation and transportation and triglyceride (TG) lipolysis and synthesis. Moreover, alterations in the inflammatory response and oxidative stress in the liver and gut microbe composition were evaluated.ResultsThe results showed that CGA decreased body weight and improved glucose tolerance and insulin resistance, and these effects were similar to those of metformin. CGA decreased hepatic lipid content by increasing the expression of CPT1a (carnitine palmitoyltransferase 1a), ACOX1 (Acyl-CoA oxidase 1), ATGL (adipose triglyceride lipase), and HSL (hormone-sensitive lipase) and decreasing that of MGAT1 (monoacylglycerol O-acyltransferase 1), DGAT1 (diacylglycerol O-acyltransferase), DGAT2, CD36, and FATP4 (fatty acid transport protein 4). Additionally, CGA restored the expression of inflammatory genes, including TNF-α (tumor necrosis factor-alpha), IL-1β (interleukin-1beta), IL-6, and IL-10, and genes encoding antioxidant enzymes, including SOD1 (superoxide dismutases 1), SOD2 (superoxide dismutases 2), and GPX1 (glutathione peroxidase 1). Furthermore, CGA improved the bacterial alpha and beta diversity in the cecum. Moreover, CGA recovered the abundance of the phylum Bacteroidetes and the genera Lactobacillus, Blautia, and Enterococcus.DiscussionCGA can improve the antidiabetic effects, and microbes may critically mediate these beneficial effects.

BackgroundHigh mobility group box protein 1 (HMGB1) is considered as a kind of sterile inflammatory mediators, which is an overexpression in patients with unexplained recurrent spontaneous abortion (URSA). Specific targeting effect of aspirin on HMGB1 has been revealed. Our previous studies have explored the application of HMGB1 as a therapeutic target of aspirin in URSA disease of mice model and human, but the dynamic process of aspirin downregulating HMGB1 concentration has not been demonstrated.MethodsFrom December 2018 to November 2020, women with URSA (n = 91) and control women (n = 90) with no history of recurrent abortion or adverse pregnancy were included in the Reproductive Medicine Center of the First Affiliated Hospital of Anhui Medical University. ELISA was applied to detect the concentrations of HMGB1 and IFN-γ in the peripheral blood. Thirty-one URSA patients were monitored for low-dose aspirin treatment (2 and 4 weeks), the changes of HMGB1 and IFN-γ concentrations in peripheral blood of URSA patients before and after using aspirin were compared, and pregnancy outcomes after aspirin treatment were followed up.ResultsThe levels of HMGB1 in peripheral blood were significantly higher in URSA patients compared with controls, decreasing trends of HMGB1 and IFN-γ concentrations in plasma of URSA patients were observed after treatment with low-dose aspirin continuously, and the expression of HMGB1 was positively correlated with IFN-γ. There were no birth abnormalities in the babies of the URSA patients treated with aspirin.ConclusionsHigh levels of HMGB1 may be one of the pathogenesis of URSA. Low-dose aspirin may provide protective effect on the HMGB1-triggered URSA.
