Backhaul-Capacity-Aware Interference Mitigation Framework in 6G Cellular Internet of Things

To meet the increasing demands for wide-band communications and network densification, a new paradigm of millimeter-wave (mmWave)-enabled integrated access and backhaul (IAB) is urgently needed in the sixth-generation (6G) cellular Internet-of-Things (IoT) network. However, the mmWave-enabled IAB technology brings new challenges on network capacity in terms of the differentiated backhaul capacities of small-cell base stations and the various interferences among access links in the 6G cellular IoT network. Therefore, this article proposes a joint traffic load-balancing and interference mitigation framework to maximize the network capacity for 6G cellular IoT services. A novel two-step resource allocation scheme is designed by optimizing the user equipment association and the transmit power allocation (PA), iteratively. Moreover, to minimize both the backhaul burden and the interference, a novel backhaul capacity and interference-aware matching utility function using the many-to-many matching model is designed to measure the interference penalty and the backhaul capacity. By transforming the nonconvex PA subproblem into a convex problem using the successive convex approximation method, both upper and lower bounds of the optimal transmit power are theoretically achieved. Simulation results prove that the proposed algorithms can significantly improve the network sum rate by 71.9% compared to the conventional algorithms, and the successful transmission probability can be well guaranteed.
Parents or teachers: whose guidance matters more in students’ alignment of educational plan and achievement? A comparative study of Taiwan and Hong Kong

ABSTRACT While existing research has well-recognized educational plan as an important predictor of students’ educational achievement, the alignment of educational plan and achievement should not be taken for granted. As plan-achievement misalignment is liable to negative psychological and social consequences, this study aims to examine the extent to which parents vis-à-vis teachers could guide students into plan-achievement alignment. Specifically, this study is set within two comparable cases of Taiwan and Hong Kong to explore whether the relative importance of parents’ and teachers’ guidance would differ according to the institutional contexts of education systems. Methodologically, society-specific (multinomial) logistic regression analyses are conducted based on the data of the Taiwan Education Panel Survey and the Hong Kong Survey on High School Students’ Aspirations for Higher Education and Employment. In Taiwan, we find students not only received more guidance from parents, but parents’ guidance was also more effective in helping them reach plan-achievement alignment. By contrast, teachers are found to have played a key role in these regards in Hong Kong. The findings provide support to our propositions that the relative importance of parents’ and teachers’ guidance may vary by the opportunity structures of post-secondary education and the level of school-based parental involvement.
Direct and indirect pathways of convected water masses and their impacts on the overturning dynamics of the Labrador Sea

<p>The dense waters formed by wintertime convection in the Labrador Sea play a key role in setting the properties of the deep Atlantic Ocean. To understand how variability in their production might affect the Atlantic Meridional Overturning Circulation (AMOC) variability, it is essential to determine pathways and associated timescales of their export. In this study, we analyze the trajectories of Argo floats and of Lagrangian particles launched at 53<sup>o</sup>N in the boundary current and traced backwards in time in a high&#8208;resolution model, to identify and quantify the importance of upstream pathways. We find that 85% of the transport carried by the particles at 53<sup>o</sup>N originates from Cape Farewell, and it is split between a direct route that follows the boundary current and an indirect route involving boundary&#8208;interior exchanges. Although both routes contribute roughly equally to the maximum overturning, the indirect route governs its signal in denser layers. This indirect route has two branches: part of the convected water is exported rapidly on the Labrador side of the basin, and part follows a longer route towards Greenland and is then carried with the boundary current. Export timescales of these two branches typically differ by 2.5 years. This study thus shows that boundary&#8208;interior exchanges are important for the pathways and the properties of water masses arriving at 53<sup>o</sup>N. It reveals a complex three&#8208;dimensional view of the convected water export, with implications for the arrival time of signals of variability therein at 53<sup>o</sup>N and thus for our understanding of the AMOC. </p>
Toward a culture-sensitive approach to playfulness research: Development of the Adult Playfulness Trait Scale-Chinese version and an alternative measurement model

Abstract The growing global interest in playfulness research calls for increasing research cross-pollination that often necessitates instrument translation with cultural sensitivity. Taking a collaborative and iterative translation approach, we developed a Chinese version of the Adult Playfulness Trait Scale–an instrument originally developed and validated in North America and increasingly used in international applications. Reliability and structural validity of the translated scale were examined using data from a national adult sample of Chinese adults (N = 1561). The results confirmed the scale’s composite reliability and a common playfulness factor shared by four sub-dimensions. Higher-order confirmatory factor analyses validated via split-sample testing revealed a distinct factorial configuration, indicating culture-specific characteristics in Chinese participants’ cognitive organization of the construct—particularly the critical role of a free, non-conforming attribute in the expression of playfulness in Chinese society. Underlying cultural causes are discussed as are implications for cultural adaptation of translated instruments and cross-cultural playfulness research.
Robust Monocular Pose Tracking of Less-Distinct Objects Based on Contour-Part Model

Due to the lack of distinctiveness to the background, robust monocular 6DOF pose tracking of less-distinct objects remains an important open problem. In this paper, we firstly analyze the object distinctiveness in the tracking process. Then, we propose a novel contour-part model based robust monocular pose tracking method for less-distinct objects. This paper uses the traditional contour feature for pose tracking in a novel strategy called contour part model. First, the contour part model is built by segmenting the projected contour rendered from the 3D model into contour segments of a certain length adaptively according to the Shi-Tomasi cornerness scores. Then, the correspondence is detected in the input image for each contour part by gradient orientation based template matching. Finally, pose tracking is achieved by solving the PnP problem. Experiment results on semi-synthetic and real images show that the proposed method performs better than the existing methods when pose tracking less-distinct objects and shows great robustness toward interference. Additionally, we combine the edge feature and the regional feature in a simple strategy. The overall performance of the fused method is boosted according to the experimental results on the RBOT dataset. The fact shows that the fusion of the edge and regional features has great potential for improving tracking performance.
Study of morphotypes and life history of six clones of Lecane bulla (Gosse, 1851) from Quintana Roo, Mexico

The genus Lecane is highly diverse, there are 209 species, most of which inhabits tropical aquatic systems. In Quintana Roo 42 species have been reported, one of these is Lecane bulla described at the widest distribution throughout the Yucatan peninsula however; their morphotypes and demographic features are unknown. Therefore, the objective of this work was identify the presence of morphotypes L. bulla and their life history traits. We evaluated life history and morphometric data of females and asexual and sexual eggs from the populations were established from clonal strains, which remained in laboratory conditions for 6 months. They were kept in a bioclimatic chamber with photoperiod of 12 hours of light and 12 hours darkness, at a 25 ± 2 °C, and were feeding with the green algae Nannochloropsis oculata at 1 × 106 cell/ml. Thirty-four clonal strains from six locations were analyzed. Statistical analysis determined significant differences between morphometric measurements (p < 0.001) in the six localities as well as showed statistically significant differences in all demographic parameters. In conclusion, this study indicates the possible coexistence in the same geographical area of two different morphotypes of L. bulla, one is a small-sized distributed in the northwest of Quintana Roo and another large-sized in the southwest.

ABSTRACT First, modified halloysite-Fe3O4 nanotubes (mHNT-Fe3O4) were synthesized. Second, mHNT-Fe3O4-Ag was synthesized by reduction process. Third, mHNT-Fe3O4-Ag was covalently incorporated into the polyurea (PUA) matrix and the mHNT-Fe3O4-Ag/PUA nanocomposites were prepared. The mHNT-Fe3O4-Ag was characterized by Fourier transform infrared spectroscopy, X-ray diffraction, UV-vis absorption spectra, transmission electron microscopy, thermogravimetric analysis, and dynamic mechanical analysis. The experimental results shown that thermal stability, tensile strength, and storage modulus of nanocomposites were improved with the increasing of the content of mHNT-Fe3O4-Ag. Meanwhile, mHNT-Fe3O4-Ag/PUA nanocomposites had excellent magnetic properties and good antibacterial property. GRAPHICAL ABSTRACT
Psychological distress and trauma in doctors providing frontline care during the COVID-19 pandemic in the United Kingdom and Ireland: a prospective longitudinal survey cohort study

Objectives The psychological impact of the COVID-19 pandemic on doctors is a significant concern. Due to the emergence of multiple pandemic waves, longitudinal data on the impact of COVID-19 are vital to ensure an adequate psychological care response. The primary aim was to assess the prevalence and degree of psychological distress and trauma in frontline doctors during the acceleration, peak and deceleration of the COVID-19 first wave. Personal and professional factors associated with psychological distress are also reported. Design A prospective online three-part longitudinal survey. Setting Acute hospitals in the UK and Ireland. Participants Frontline doctors working in emergency medicine, anaesthetics and intensive care medicine during the first wave of the COVID-19 pandemic in March 2020. Primary outcome measures Psychological distress and trauma measured using the General Health Questionnaire-12 and the Impact of Events-Revised. Results The initial acceleration survey distributed across networks generated a sample of 5440 doctors. Peak and deceleration response rates from the original sample were 71.6% (n=3896) and 56.6% (n=3079), respectively. Prevalence of psychological distress was 44.7% (n=1334) during the acceleration, 36.9% (n=1098) at peak and 31.5% (n=918) at the deceleration phase. The prevalence of trauma was 23.7% (n=647) at peak and 17.7% (n=484) at deceleration. The prevalence of probable post-traumatic stress disorder was 12.6% (n=343) at peak and 10.1% (n=276) at deceleration. Worry of family infection due to clinical work was the factor most strongly associated with both distress (R2=0.06) and trauma (R2=0.10). Conclusion Findings reflect a pattern of elevated distress at acceleration and peak, with some natural recovery. It is essential that policymakers seek to prevent future adverse effects through (a) provision of vital equipment to mitigate physical and psychological harm, (b) increased awareness and recognition of signs of psychological distress and (c) the development of clear pathways to effective psychological care.

The Influence of the Window Width on FRA Assessment with Numerical Indices

Frequency response analysis is a method used in transformer diagnostics for the detection of mechanical faults or short-circuits in windings. The interpretation of test results is often performed with the application of numerical indices. However, usually these indices are used for the whole frequency range of the recorded data, returning a single number. Such an approach is inaccurate and may lead to mistakes in the interpretation. An alternative quality assessment is based on the estimation of the local values of the quality index with the moving window method. In this paper, the authors analyse the influence of the width of the input data window for four numerical indices. The analysis is based on the data measured on the transformer with deformations introduced into the winding and also for a 10 MVA transformer measured under industrial conditions. For the first unit the analysis is performed for various window widths and for various extents of the deformation, while in the case of the second the real differences between the frequency response curves are being analysed. On the basis of the results it was found that the choice of the data window width significantly influences the quality of the analysis results and the rules for elements number selection differ for various numerical indices.
Grit and language learning: construct validation of L2-Grit scale and its relation to later vocabulary knowledge

Abstract The present study aimed to empirically examine the validity of grit among language learners and its relation to vocabulary knowledge. Grit is defined as a trait that is characterised by a tendency to be passionate about and persevere towards the achievement of long-term goals. A newly developed questionnaire, L2-Grit Scale, which assesses perseverance of effort and consistency of interest in language learning was used. The construct validity was evaluated, and bi-factor CFA was supported. The convergent and divergent validity of the grit constructs were tested against operationalisations of related motivational constructs. The results suggest that the L2-Grit Scale is, reliable, valid and suitable for use in L2 research. With regard to predictive validity, grit has shown to have a non-significant direct effect on later vocabulary knowledge. Rather, initial grit was only indirectly associated with later vocabulary knowledge through the mediation role of later endorsement of grit.

Benign breast disorders and diseases in rural Andhra Pradesh: A prospective study

Background: Throughout life period of female, breast is subjected to constant physical and physiological alterations that are related to puberty, menstrual cycle, pregnancy, lactation, and menopause. Benign breast diseases (BBD) constitute a heterogeneous group of breast lesions which include developmental abnormalities, inflammatory and granulomatous lesions, epithelial and stromal proliferations, and neoplasms.Methods: This is a prospective study of females with breast disease presenting to surgery department over a period of one year. Malignant cases or benign cases treated earlier are excluded from the study. In addition to detailed history, triple assessment including thorough clinical examination, imaging study and tissue biopsy was done to arrive at a diagnosis. Investigations included routine hematological in all patients and imaging (ultrasonography and mammography) in some.Results: Most common BBD is fibroadenoma followed by mastalgia, breast abscess and fibrocystic disease in our population. Commonest way of presentation was lump in breast followed by mastalgia and nipple discharge.Conclusion: Benign breast diseases are common problems of 2nd and 3rd decade in females and raises considerable fear of malignancy. The patients of BBDs generally present with one or more of these complaints–breast lump, breast pain or nipple discharge. All the patients with discrete breast lumps should undergo a triple assessment to make an early diagnosis.
Perceiving commitments: When we both know that you are counting on me

Funding information Central European University ERC Starting, Grant/Award Number: 679092; SENSE OF COMMITMENT ERC Synergy, Grant/Award Number: 609819, SOMICS Can commitments be generated without promises or gestures conventionally interpreted as such? We hypothesized that people believe that commitments are in place when one agent has led a recipient to rely on her to do something, even without a commissive speech act or any action conventionalized as such, and this is mutual knowledge. To probe this, we presented participants with online vignettes describing everyday situations in which a recipient's expectations were frustrated by one's behavior. Our results show that moral judgments differed significantly according to whether the recipient's reliance was mutually known, irrespective of whether this was verbally acknowledged.
Towards teacher innovative work behavior: A conceptual model

Abstract To discover the predictors of teacher innovative work behavior, the authors surveyed 232 EFL teachers. Three instruments, including Urtecht Work Engagement Scale questionnaire, Dimensions of Learning Organization Questionnaire (Marsick & Watkins, 2003), and Innovative Work Behavior questionnaire were employed to examine the predictors of teachers’ innovation. The results demonstrated that learning organization not only positively predicted work engagement but also it acted as a significant positive predictor of innovative work behavior. Additionally, analysis of the data provided evidence on work engagement as an antecedent of teachers’ innovative work behavior. Finally, work engagement partially mediated the relationship between learning organization and innovative work behavior.
Improved Topotactic Reactions for Maximizing Organic Coverage of Methyl Germanane

The topotactic transformation of Zintl phases such as CaGe2 into organic-terminated germanium graphane analogues using haloalkanes is a powerful route for generating new 2D optoelectronic and spintronic building blocks. However, uniform ligand coverage is necessary for optimizing the properties and stability of these single-atom-thick frameworks. Here, we compare the effectiveness of different topochemical methods to maximize methyl-termination in GeCH3. We show that a previously developed CH3I/H2O phase transfer route produces a small percentage of partially oxidized germanane. The partially oxidized termination is readily removed upon HCl treatment, which leads to Ge–Cl termination, but rapidly reoxidizes after exposure to the ambient atmosphere. We then show that a one-pot route with CH3I in distilled CH3CN solvent and at least six equivalents of H2O results in no oxidation. The GeCH3 prepared from this one-pot route also has an increased −CH3/–H ratio of termination from ∼90:10 to ∼95:5, is air-stable.
Effect of Cooking Methods on Bioactive Compounds of Eggplant (Solanum melongena L.) and its Use in Preparing and Evaluating Frozen Baba Ghanoush Product During Storage

This research was undertaken to find out the effects of different cooking methods on bioactive compounds of eggplant. The effect of freezing and storage on microbial growth and sensory properties of the common Egyptian dish called Baba ghanoush were also studied. The results showed that eggplant contained a high percentage of crude fiber, crude protein, crude fat, and total ash. It can be noted that the mineral contents of fresh eggplant were Ca, Mg, Na and K as the major minerals. On the other hand, the results of total phenolics in the fresh, dry fresh, oven and steamed samples were 9.32, 75.78, 42.31 and 41.53 mg/100 g, respectively as gallic acid equivalent. The total flavonoids of the different eggplant treated samples varied between 0.46 to 0.7 mg equivalents of quercetin per 100 g. The results indicated that the antioxidant activity as well as IC50 of fresh, dry fresh, oven and steamed samples were 8.82, 87.20, 82.78, 90.23 and 10.86, 1.18, 1.21 and 1.12, respectively. Also, eighteen phenolic compounds were identified by HPLC. The color attributes L*, a*, and b* in case of Baba ghanoush prepared from oven eggplant slightly decreased with increasing the storage period. Significant reduction was noted in microbial growth with increasing the storage period up to 4 months in case of Baba ghanoush prepared either from oven and steamed eggplant. Sensory attributes of Baba ghanoush were well accepted by the panelists even after 4 months of storage.
Experimental Study on Performance and Combustion Analysis of a Diesel Engine Fueled with Diesel and Jatropha Oil Blended with Heptane

This work focuses on blending Jatropha oil with diesel fuel and heptane to improve its physico-chemical characteristics for production of blends and their use as fuel in a diesel engine. The influence of the heptane content was evaluated by comparing the results obtained from the engine (performance and combustion parameters) with those of the diesel fuel and straight Jatropha oil. The results obtained show an improvement in engine performance especially at low loads. Specifically, a reduction in the specific fuel consumption of the engine is obtained when the heptane content in the mixture is around 10% compared to that obtained with pure Jatropha oil. The best results were obtained with the blend containing 70% Jatropha oil, 20% diesel fuel and 10% heptane (J70G20H10). Overall engine efficiency and exhaust gas temperatures are comparable for all fuels tested. Engine combustion parameters are improved with J70G20H10. The results obtained with J70G20H10 are close to those of the engine operating on diesel fuel. The cyclic dispersion is low with coefficients of variation of the indicated mean effective pressure (COVIMEP) whose values are less than 10%. The lowest values of the COVIMEP are obtained with the blend J70G20H10.
