Classical, refined, zig-zag and layer-wise models for laminated structures

This chapter overviews classical and advanced theories for laminated plates and shell structures. Findings from existing historical reviews are used to confirm that the advanced theories can be grouped and referred to as: Lekhnitskii multilayered theories, Ambartsumian multilayered theories, and Reissner multilayered theories. The unified formulation proposed by the first author, which is known as CUF (Carrera’s unified formulation), is used to make numerical assessments of various laminated plate/shell theories. The chapter ends by giving details of a recent reliable finite element formulation for laminated shell analysis. It is embedded in the CUF framework and it leads to the classical, zig-zag, and layer-wise models as particular cases. Numerical mechanisms such as shear and membrane locking are contrasted by developing an appropriate choice of shape functions and mixed assumed shear strain techniques.
Investigation on Intermittent Failure Phenomenon of Electrical Connectors Under Repetitive Mechanical Insertion and Withdrawal Operations

Electrical connectors play an indispensable role in electrical and electronic systems. The frequently occurred intermittent failure events seriously affect the reliability of application systems. In this article, the repetitive mechanical insertion and withdrawal experiment of electrical connector is carried out by using our designed test rig and the intermittent failure phenomena recurs. The typical waveforms of contact resistance and force during the mating operation are presented. The variation laws of static contact resistance and dynamic contact resistance under intermittent failure condition are counted and analyzed. And the dynamic contact resistance is proven to be a suitable sensitive parameter to characterize the intermittent failure event. Based on the mathematical model, variation of surface morphology, and element analysis, the failure mechanism of electrical connectors under repetitive operation is proposed.
Efficient Reliable Wireless Communications through Raptor Codes and Rateless Codes with Feedback

Multi-connectivity can increase the reliability of wireless communications by orders of magnitude due to an increased diversity. However, simply copying packets and sending them on multiple links in parallel, i. e. , as standardized as packet duplication, will result in a wasteful scheme. For example, there is no benefit in receiving the same information more often than once if multiple links succeed. This drawback can be resolved by channel coding. In a previous work, we proposed packet transmission schemes based on rateless codes, which could already increase resource efficiency compared to packet duplication. Here, we extend our previous studies in two different ways. First, we replace the previously used random linear fountain code by a more sophisticated raptor code, namely the R10 code. Second, we investigate a scenario, where the rateless coding scheme, which typically does not need any feedback, has acknowledgement information available. Both proposals show significant benefits of up to 15 % compared with our previous work in our mathematical analysis and empirical simulations.
Inheritance of Resistance to Mechanical Damage and Transverse Cotyledon Cracking in Snap Beans (Phaseolus vulgaris L.)1

Colored and white seeded inbred bean lines resistant to mechanical damage (MD) and transverse cotyledon cracking (TVC) were crossed with 2 susceptible white seeded snap bean cultivars. Resistance to both MD and TVC was inherited quantitatively although colored segregants were more resistant than white-seeded segregants, MD and TVC resistant white-seeded selections were obtained. Broad-sense heritability varied from 55 to 79% for MD and 53 to 93% for TVC; narrow-sense heritability resistance varied from 22 to 73% for MD and from 22 to 58% for TVC. Severe selection pressure for MD resistance on bulked F3 seed was shown to be a simple and practical method to obtain resistance.
Neuro-immune interactions at single-cell resolution in neurodevelopmental, infectious, and neurodegenerative diseases

ABSTRACT Recent technological advance in single-cell and single-nucleus transcriptomics has made it possible to generate an unprecedentedly detailed landscape of neuro-immune interactions in healthy and diseased brains. In this review, we overview the recent literature that catalogs single-cell-level gene expression in brains with signs of inflammation, focusing on maternal immune activation, viral infection, and auto-immune diseases. The literature also includes a series of papers that provide strong evidence for immunological contributions to neurodegenerative diseases, which, in a strict sense, are not considered neuroinflammatory. To help with the discussion, we present a diagram of experimental and analytical flows in the single-cell analysis of the brain. We also discuss the recurring themes of neuro-immune interactions and suggest future research directions.
Normalization-Based Approach to Electric Motor BVR Related Capacitances Computation

Electrical discharge machining bearing currents that may occur within electric machines of variable-speed-drive motor systems have been recognized for a long time. One key influential factor, the machine's capacitive voltage divider “bearing-voltage-ratio” (BVR) strongly depends on the rotor-to-frame and the stator winding-to-rotor capacitances; these are, in turn, affected by the design of the machine's stator slot. This paper presents an approach to improve the accuracy with which these capacitances can be estimated. It is based on the well-known plate capacitance equation which is then corrected by normalization functions. The functions are defined by extensive parameter studies using electrostatic finite element method (FEM) simulations. The final expressions not only allow for the prediction of the stator-winding-to-rotor and rotor-to-frame capacitances, they are also readily applicable. Thereby, they facilitate, for example, the clear-cut study of the sensitivity of the BVR towards changes in the different stator slot parameters.
EFL students' perspectives on the use of Wordwall.net as vocabulary learning media

Using ICT tools to teach vocabulary is a commonly researched topic in language teaching. Many popular web tools, such as Kahoot and Quizizz, are used as experimental tools with learners to investigate how effectively they enhance learners' vocabulary. This study analyzed the students' perceptions of Wordwall.net, a less known and researched game-based web tool, in their vocabulary learning. This study was conducted since there is still limited research conducted in Indonesia that analyses the students' perception of using Wordwall.net in English vocabulary learning. This research design was survey research with a sample of 29 8th-grade students at one of the Junior High Schools in Bengkulu Tengah. The data were collected using a close-ended questionnaire. It was analyzed quantitatively by implementing the Likert scale. The result of this research found that most students' perception of the use of Wodwall.net in their vocabulary learning was positive. Their feeling about Wordwall.net was great. They enjoyed the teamwork and competition; they perceived Wordwall.net as an exciting, interesting, motivating & fun web tool to learn vocabulary. From the students' perceived effects of using Wordwall.net, Wordwall.net was a kind of awaited learning media for the students. In addition, Wordwall.net also influenced the students' engagement with the web tool and the classroom. It indicated that the students paid more attention to the learning process. The researchers strongly recommended that teachers start using Wordwall.net to learn vocabulary based on the results.
Efficacy and Safety of Low-Dose Brexpiprazole for Acute Schizophrenia: Meta-Analysis of Randomized Placebo-Controlled Trials

Purpose The purpose of this meta-analysis was to compare the efficacy and safety profile of low-dose brexpiprazole (<2 mg/d) compared to placebo and standard-dose brexpiprazole (2–4 mg/d). Patients and Methods We identified relevant studies pertaining to the specific purpose of our meta-analysis by searching PubMed, Web of Science, Embase, Cochrane library, and PsycINFO using the search terms “schizophrenia” or “schizophrenic” AND “brexpiprazole” or “REXULTI”. We systematically reviewed all randomized controlled trials (RCTs) comparing low-dose brexpiprazole with placebo. Primary efficacy outcomes were the PANSS total score change and response rate. Primary safety outcomes were total treatment discontinuation rate, and total serious adverse events (SAEs). Risk ratios (RR) and standardized mean differences (SMDs) were pooled implementing a random effect model. Results Four RCTs (2178 patients) were included for effect assessment of low-dose brexpiprazole treatment on the patients with acute schizophrenia. Low-dose brexpiprazole was not superior to placebo (SMD = −0.11, 95% CI = −0.23, 0.02, P = 0.10, I2 = 0%), and significantly inferior to standard-dose brexpiprazole (SMD = 0.15, 95% CI = 0.03, 0.26, P = 0.01, I2 = 0%) for PANSS total score change. Low-dose brexpiprazole did not result in significant difference for response rate when compared to placebo and standard-dose brexpiprazole (RR = 1.16, 95% CI = 0.95, 1.41, P = 0.14, I2 = 25%; RR = 0.92, 95% CI = 0.76, 1.12, P = 0.40, I2 = 38%, respectively). For ratio of total discontinuation, low-dose brexpiprazole did not exhibit significant difference when compared to placebo (RR = 0.95, 95% CI = 0.81, 1.11, P = 0.53, I2 = 0%) and standard-dose brexpiprazole group (RR = 1.11, 95% CI = 0.95, 1.29, P = 0.19, I2 = 0%). Total SAEs in low-dose brexpiprazole group did not differ significantly from placebo and standard-dose brexpiprazole group (RR = 0.96, 95% CI = 0.52, 1.80, P = 0.90, I2 = 0%; RR = 1.29, 95% CI = 0.65, 2.57, P = 0.47, I2 = 26%, respectively). Conclusion The results indicated that low-dose brexpiprazole may be not superior for improving the efficacy and safety for acute schizophrenia compared to placebo and standard-dose brexpiprazole, and may cause additional risk of increasing body weight. Therefore, using low-dose brexpiprazole in acute schizophrenia patients may be not recommended.
A Radon-Nikodym theorem for the v-integral.

Suppose Σ is a σ-field of subsets of a nonempty set S and μ is a nonnegative, countably additive measure function defined on Σ and S is the union of a countable number of sets of finite measure. If f is a μ-integrable function, then for each E € Σ with μ (E) < oo \eiv(E) = Jfd/j where the integral is a Frechet-Lebesgue type integral. It follows that the E countably additive measure v is absolutely continuous with respect to μ. The classical Radon-Nikodym theorem states that this is a tautology, that is, if v is finite and absolutely continuous with respect to μ, then there exists a function f such that for each E € Σ, v (E) = f fdμ. The equivalence class[f] of functions which are μ-almost everywhere equal
Mediastinal melioidosis: A case series from far North Queensland

Melioidosis is the clinical disease caused by the Gram‐negative bacillus Burkholderia pseudomallei and is endemic to Northern Australia and Southeast Asia. It is commonly referred to as the ‘great mimicker’ because of its wide range of clinical presentations, often making diagnosis challenging. Isolated mediastinal lymphadenopathy as the presenting feature of melioidosis is rare and can be indistinguishable from tuberculosis or malignancy. Endobronchial ultrasound (EBUS) is the preferred technique for evaluating undifferentiated mediastinal lymphadenopathy but its role in the diagnosis of mediastinal melioidosis remains sparsely reported in the literature. In this case series, we present four cases of mediastinal melioidosis, and the role that EBUS guided fine needle aspiration (FNA) played in the diagnosis and management.
Undergraduate Students’ Perceptions towards the Process of Writing

Writing process has been proven to be an effective approach to enhance students’ writing performance. The writing process consists of pre-writing, drafting, revising, and editing. The writing process aids the students in developing ideas while writing, but it was claimed that students also face challenges during the process. Therefore, this current study aimed to investigate the students’ perceptions of the writing process and the challenges. The subjects taken were the first-year students of the English Educational program at the State University of Malang, in which 31 students of IC Writing Class were chosen. The perceptions were investigated through a survey study by distributing online questionnaires via Google Form. The questionnaire was divided into four aspects; pre-writing, drafting, revising, and editing, which aimed at exploring the students’ perceptions during the writing process and its challenges. The findings of the study showed that the students experienced difficulties in the writing process. The most challenging stages they had were the pre-writing and revising stage. The students faced challenges in generating and structuring ideas, respectively. Meanwhile, the students claimed that drafting and editing were less challenging since they followed the preceding stage. Nonetheless, the students also believed that proofreading was a complex process in the editing stage. The results of this study will be beneficial for English teachers and future researchers to vary the teaching methodology and reflect a better analysis.
Influence of surface charge decay on cavity PD frequency at DC voltage

In this study, two types of samples, i.e. a disc-shaped cavity embedded within solid dielectrics and the other on an electrode surface, were used to investigate partial discharge (PD) behaviours at DC voltage. It has been found that the discharge frequency of the sample with one metallic surface was much larger under a positive voltage than under a negative one, whereas it was not sensitive to voltage polarities for the sample with two insulating surfaces. In order to explain experimental results, a simulation model based on continuity equations was established to obtain PD sequences at DC voltage, in which surface charge decay and discharge time lag were taken into account. Simulation results showed that positive surface charges dissipated faster than the negative, and the discharge time lag kept almost unchanged at the same voltage amplitude. The discharge time interval consisted of field recovery time and discharge time lag, and the former was determined by surface charge decay rate. In terms of these, the effect of surface charge decay on discharge frequency was discussed. The research is helpful to clarify PD mechanism at DC voltage.
Cranberry Growth Related to Tissue Concentration and Soil Test Phosphorus1

Phosphorus stress caused a general restriction of growth, pinkish tips and purplish leaves and was associated with low tissue P concn. Phosphorus concn for severe deficiency ranged from 0.034 to 0.08%, hidden hunger occurred from 0.09 to 0.11%, and sufficiency 0.12 to 0.27%. Phosphorus removed from the nutrient solutions was recovered in the plants. Soil test P at 50-70 kg/ha did not limit growth.
Effect of Pulse Polarity and Dielectric Configuration on the Spatio-Temporal Evolution Characteristics of Methane Pulsed Dielectric Barrier Discharge Plasma

Plasma assisted CH4 directly converse into higher hydrocarbons has received particular attention in controlling the energy depletion and environmental pollution. The current work establishes the kinetic model of methane pulsed dielectric barrier discharge (DBD) plasma to investigate the spatio-temporal evolution characteristics under the double dielectric positive pulsed DBD (DDBD), single dielectric positive pulsed DBD (SP DBD), and single dielectric negative pulsed DBD (SN DBD) at atmospheric pressure. The results show that the emergence of peak values (discharge current densities, average electron temperatures and densities.) are later and smaller under DDBD compared with that under SP DBD and SN DBD. In DDBD, the distributions of the species are uniform over the plasma area at the beginning of the discharge, and then move toward the anode, gradually the species accumulate towards the cathode with the cathode sheath formed. As the discharge proceeding, the species principally distribute on the cathode. Unlike the DDBD, the majority of the species are concentrated on the anode at the start of discharge under SP DBD, then the species move toward the cathode over time. And the species mainly distribute on both electrodes. Furthermore, the species spatial distributions under SN DBD are symmetrical to that in SP DBD.
Maintenance of specificity in sympatric host-specific fig/wasp pollination mutualisms

Background Fig/wasp pollination mutualisms are extreme examples of species-specific plant-insect symbioses, but incomplete specificity occurs, with potentially important evolutionary consequences. Why pollinators enter alternative hosts, and the fates of pollinators and the figs they enter, are unknown. Methods We studied the pollinating fig wasp, Ceratosolen emarginatus, which concurrently interacts with its typical host Ficus auriculata and the locally sympatric alternative host F. hainanensis, recording frequencies of the wasp in figs of the alternative hosts. We measured ovipositor lengths of pollinators and style lengths in female and male figs in the two host species. Volatile organic compounds (VOCs) emitted by receptive figs of each species were identified using GC-MS. We tested the attraction of wasps to floral scents in choice experiments, and detected electrophysiologically active compounds by GC-EAD. We introduced C. emarginatus foundresses into figs of both species to reveal the consequences of entry into the alternative host. Results C. emarginatus entered a low proportion of figs of the alternative host, and produced offspring in a small proportion of them. Despite differences in the VOC profiles of the two fig species, they included shared semiochemicals. Although C. emarginatus females prefer receptive figs of F. auriculata, they are also attracted to those of F. hainanensis. C. emarginatus that entered male figs of F. hainanensis produced offspring, as their ovipositors were long enough to reach the bottom of the style; however, broods were larger and offspring smaller than in the typical host. Female figs of F. hainanensis failed to produce seeds when visited by C. emarginatus. These findings advance our current understanding of how these species-specific mutualisms usually remain stable and the conditions that allow their diversification.
Inference on spatial heterogeneity in tumor microenvironment using spatial transcriptomics data

In the tumor microenvironment (TME), functional interactions among tumor, immune, and stromal cells and the extracellular matrix play key roles in tumor progression, invasion, immune modulation, and response to treatment. Intratumor heterogeneity is ubiquitous not only at the genetic and transcriptomic levels but also in the composition and characteristics of TME. However, quantitative inference on spatial heterogeneity in the TME is still limited. Here, we propose a framework to use network graph-based spatial statistical models on spatially annotated molecular data to gain insights into modularity and spatial heterogeneity in the TME. Applying the framework to spatial transcriptomics data from pancreatic ductal adenocarcinoma samples, we observed significant global and local spatially correlated patterns in the abundance score of tumor cells; in contrast, immune cell types showed dispersed patterns in the TME. Hypoxia, EMT, and inflammation signatures contributed to intra-tumor spatial variations. Spatial patterns in cell type abundance and pathway signatures in the TME potentially impact tumor growth dynamics and cancer hallmarks. Tumor biopsies are integral to the diagnosis and clinical management of cancer patients; our data suggest that owing to intra-tumor non-genetic spatial heterogeneity, individual biopsies may underappreciate the extent of clinically relevant, functional variations across geographic regions within tumors.
Design and Multi-Objective Stratified Optimization of a Less-Rare-Earth Hybrid Permanent Magnets Motor With High Torque Density and Low Cost

The price fluctuation and the unstable supply chain of rare-earth permanent magnet (PM) have posed potential risks for further application of rare-earth PM motors. To alleviate the consumption of rare-earth PM material, a less-rare-earth PM brushless motor with two types of PM materials is proposed in this paper. The key of this motor is that the rare-earth PM is purposely combined with a non-rare-earth ferrite PM, forming the hybrid PM excitation. To design the proposed motor efficiently, a multi-objective stratified optimization strategy is proposed, where the selected five optimization objectives of output torque, PM cost, cogging torque, torque ripple, and efficiency are divided into two levels. Then, different optimization methods are skillfully combined to meet the specific design requirements. The corresponding electromagnetic performances are analyzed and compared with the baseline rare-earth PM brushless motor. Finally, several experiments of the two motors are carried out for evaluation. Both theoretical analysis and experimental results verify the feasibility and validity of the proposed motor and the optimization method.
The The Development of Vocabulary and Overall Proficiency in English as an Additional (Third) Language. What Matters More, Daily Use or Age of Onset?

While seminal work identified age of onset to L2 as a core predictor of L2 learning in naturalistic environments, recent research has shown that other variables, such as language use, are more important than an early age of onset in predicting L2 attainment in speakers who learn the second language primarily in school. In this study, we investigated whether the acquisition of vocabulary and the development of overall proficiency in English as L2 can be predicted more faithfully by daily language, intended as daily share of L2 use in comparison to L1s, or L2 age of onset. To explore this issue, we analyzed a large public dataset of 650 speakers (de Bruin et al., 2017), in which participants were native in Spanish and/or Basque and spoke English as an additional language. Participants were previously assessed on their vocabulary skills using the LexTALE task and on their overall proficiency using a semi-structured interview. Language skills were then added to a linear regression model where age of onset and daily use of English were treated as predictors. Our results show that, in this dataset, use is a better predictor of language skills (both lexical knowledge and overall proficiency) than age of onset.
Revalorizing a Pyrolytic Char Residue from Post-Consumer Plastics into Activated Carbon for the Adsorption of Lead in Water

This work focuses on the use of a char produced during the pyrolysis of a mixture of non-recyclable plastics as a precursor for the preparation of porous activated carbon with high developed adsorption uptake of lead in water. Physical and chemical activation was used to enhance the porosity, surface area, and surface chemistry of char. The final activated carbon materials were deeply characterized through N2 adsorption isotherms, scanning electron microscopy, Fourier transformed infrared spectroscopy, analysis of the metal content by inductively coupled plasma mass spectroscopy, and pH of point zero charge. The native char displayed a Pb adsorption uptake of 348 mg Pb·g−1 and considerably high leaching of carbon, mainly organic, ca. 12%. After stabilization with HCl washing and activation with basic character activators, i.e., CO2, NaOH, and KOH, more stable adsorbents were obtained, with no organic leaching and a porous developed structure, the order of activation effectiveness being KOH (487 m2·g−1) > NaOH (247 m2·g−1) > CO2 (68 m2·g−1). The activation with KOH resulted in the most effective removal of Pb in water with a saturation adsorption uptake of 747 mg Pb·g−1.
