Expansion of the multifunctionality in off-stoichiometric manganites using post-annealing and high pressure: physical and electrochemical studies.

Prospects for the use of manganites in various areas of modern technologies require comprehensive studies of their physical and chemical properties. La0.9Mn1. 1O3 (LMO) ceramics have been synthesized at an annealing temperature tann of 1150 °C with further post-annealing at 1250, 1350, and 1450 °C. As tann increases, the structure symmetry changes, and both the crystallite size and chemical defects increase. The post-annealing, on one hand, leads to a dramatic reduction of the magnetocaloric effect (MCE) |-ΔSmaxM| from 3.50 to 0.75 J (kg K)-1 at 2 T and a Curie temperature TC from 227 to 113 K with increasing tann. On the other hand, an external hydrostatic high-pressure P works oppositely enhancing ferromagnetic interactions. The saturation of -ΔSmaxM and TC is already achieved at a relatively low P of ≈ 0.4 GPa. LMO-1150 exhibits the best magnetocaloric characteristics compared with other studied samples. Moreover, the electrochemical characteristics of the LMO materials as electrocatalysts for overall water splitting (OER process) and features of their transformation in different 0.5 M K2SO4, 0.5 M K2HPO4, and 0.1 M K2B4O7 electrolytes have been studied thoroughly. After electrocatalysis of LMO, the magnetization M decreases and TC remains, which makes it possible to control the depletion of electrodes and predict their working time based on the magnetic measurements. All samples show the best OER activity in the 0.5 M K2HPO4 media. The obtained results demonstrate the ways for controlling the MCE of LMO under changing internal and external conditions, and an evaluation of the possibilities for their OER applications in electrocatalysts.
Analysis of the Composition of Bromide Anion Oxidation Products in Aqueous Solutions with Different pH via Rotating Ring-Disk Electrode Method

We measured the ring collection coefficient of bromide anion oxidation products in a neutral and slightly alkaline medium on a rotating ring-disk electrode (glassy carbon disk, platinum ring) varying the following parameters: disk electrode rotation velocity, sodium bromide concentration, pH of the medium (in the range of 6–12), anode current on the disk, and the electroreduction potential of the bromide anion oxidation products on the ring. The data obtained are presented via dependences of the cathode ring current on the disk current ratio vs. the ring electrode potential. The analysis of the results was carried out by comparing the experimental polarization curves of the ring electrode with the data of cyclic voltammetry in model solutions to determine the electrical activities of various bromine compounds in positive oxidation states. We claim that the RRDE method could be used to obtain quantitative and qualitative data on the electrooxidation of bromide ions in neutral and alkaline solutions. For the most effective regeneration of the spent oxidizer, the values of pH > 10 and moderate concentrations of NaBr should be used.
Quantitation of 1,4-Dichlorobenzene and Thymol in Beeswax Using Dynamic Headspace Vacuum Transfer in Trap Extraction Prior to Gas Chromatography-Mass Spectrometry

A method based on dynamic headspace vacuum transfer in trap extraction, followed by gas chromatography coupled with a mass spectrometer (DHS-VTT-GC-MS), was validated for the fast quantitation of 1,4-dichlorobenzene (p-dichlorobenzene; PDCB) and thymol residues in beeswax. The quantitation limits (LOQ) were 0.05 mg/kg (PDCB) and 0.25 mg/kg (thymol). Recoveries above 80% were obtained for PDCB concentrations between 0.05 and 10 mg/kg and for thymol concentrations between 0.25 and 200 mg/kg. Analysis of beeswax samples showed a good correlation between the results obtained by DHS-VTT-GC-MS analysis and those of a previous method based on SPE extraction followed by gas chromatography and triple- quadrupole mass spectrometry (GC-MS/MS) (R2 = 0.9770 for PDCB and 0.9666 for thymol). However, the sample preparation and chromatography were much shorter using the DHS-VTT-GC-MS method. Forty comb foundations samples produced in Switzerland in 2019 and 2021 were analysed using DHS-VTT-GC-MS. Fourteen samples contained PDCB above the LOQ of 0.05 mg/kg, ranging up to a maximum of 1.53 mg/kg. The mean concentration of the positive samples was 0.22 mg/kg. All samples contained thymol residues ranging between 3.9 and 84.4 mg/kg with mean and median concentrations of 22.7 mg/kg and 17.4 mg/kg. Residue levels of PCDB and thymol in Swiss beeswax were substantially below those measured 20 (PDCB) and 10 (thymol) years ago, respectively.
Sudden Sensorineural Hearing Loss after Third Dose Booster of COVID-19 Vaccine Administration

Coronavirus disease 2019 (COVID-19) was declared a pandemic due to its rapid spread worldwide, and its vaccination campaign is considered one of the most historic public hygiene measures in modern medicine. Sudden sensorineural hearing loss (SSHL) is a common emergency that affects patient’s quality of life and requires rapid treatment with steroids. The etiology could be viral or vascular even though in most cases it remains unknown (idiopathic SSHL). During the SARS-CoV-2 vaccination campaign, several rare but serious adverse events have been reported including thrombosis with thrombocytopenia syndrome, myocarditis, and Guillain-Barré Syndrome. ENT adverse events after vaccination were reported too, including cases of sudden sensorineural hearing loss (SSHL), vestibular neuronitis and audio vestibular disorders (such as tinnitus, dizziness, and vertigo). For the first time here, we reported two cases of SSHL after third administration of COVID-19 mRNA vaccine. Even if there is not clear evidence of an association between SSHL and vaccination, adverse effects should be kept in mind since viral infection could be the etiology of SSHL.
Rheological Properties and Stability of Thickeners for Clinical Use

The adaptation of liquids for patients with dysphagia requires precision and individualization in the viscosities used. We describe the variations of viscosity in water at different concentrations and evolution over time of the three compositions of commercial thickeners that are on the market (starch, starch with gums, and gum). By increasing the concentration in water, the viscosity of gum-based thickeners increases linearly, but it did not reach pudding texture, whereas the viscosity of the starch-based thickeners (alone or mixed with gums) rapidly reaches very thick textures. We modeled the viscosity at different concentrations of the four thickeners using regression analysis (R2 > 0.9). We analyzed viscosity changes after 6 h of preparation. The viscosity of gum-based thickeners increased by a maximum of 6.5% after 6 h of preparation, while starch-based thickeners increased by up to 43%. These findings are important for correct handling and prescription. Gum-based thickeners have a predictable linear behavior with the formula we present, reaching nectar and honey-like textures with less quantity of thickener, and are stable over time. In contrast, starch thickeners have an exponential behavior which is difficult to handle, they reach pudding-like viscosity, and are not stable over time.
Autologous Platelet Concentrates (APCs) for Hard Tissue Regeneration in Oral Implantology, Sinus Floor Elevation, Peri-Implantitis, Socket Preservation, and Medication-Related Osteonecrosis of the Jaw (MRONJ): A Literature Review

Simple Summary Autologous platelet concentrates with high growth factor levels are used in many fields of dentistry. In recent years, the critical role of blood-derived materials in bone and soft tissue engineering has become apparent. After tooth extraction, the alveolar bone is exposed to progressive bone resorption, which can lead to difficulties in implant placement. Hence, many studies have demonstrated that APCs have the potential for soft tissue and bone regeneration. Furthermore, no inflammatory reactions occur, and they may be used alone or in combination with bone grafts, promoting bone growth and maturation. Moreover, the released growth factors and the presence of fibrin structures can induce osteogenesis. This review aims to provide information regarding the applications, indications, advantages, and disadvantages of three APC techniques in hard tissue regeneration. Abstract Over recent years, the usage of autologous platelet concentrates (APCs) has risen in hard tissue regeneration and oral implantology. The purpose of the present review is to offer an overview of the use of three APC techniques in dentistry: platelet-rich plasma (PRP), platelet-rich fibrin (PRF), and concentrated growth factor (CGF). A narrative summary of articles published between January 2011 and April 2022 is provided. The PubMed, Cochrane Library, Scopus, and Embase databases were used to conduct the search. The following keywords were used in the preliminary: “VEGF”, “TGF-b1”, “PRP”, “PRF”, “CGF”, AND “sinus augmentation” OR “implants” OR “peri-implantitis” OR “socket preservation” OR “MRONJ”. A total of 82 articles was finally included. The review then takes into account the application of the three techniques in different areas of treatment—including oral implantology, sinus floor elevation, peri-implantitis, socket preservation, and medication-related osteonecrosis of the jaw (MRONJ)—as well as their advantages and disadvantages.
Developmental events in the lung of the Japanese quail (Coturnix coturnix japonica): Morphological, histochemical and electron‐microscopic studies

The lung of birds is the most complex and efficient gas exchanger in the air‐breathing vertebrates. A total number of 27 normal Japanese quail embryos during the pre‐hatching period were used. The current work aimed to investigate the histomorphological, histochemical and ultrastructural changes of the lung at different stages of development using light and electron microscopy. The results showed that the respiratory primordium was observed on the 2nd embryonic day (ED) as a ventral out‐pouching of the primitive foregut into the surrounding mesenchyme. The first evidence of the lung buds appeared on the 3rd ED. On the 4th ED, the buds increased in size. In addition, the secondary bronchi budded from the epithelial lining of the primary bronchus into the surrounding mesenchyme. On the 6th ED, the number of the secondary bronchi increased and began to give rise small tubules (parabronchi). On the 7th ED, telocytes (TCs) were seen extensively in relation to the undifferentiated mesenchymal cells (UMC) and surrounding the developing bronchi and blood vessels. On the 8th ED, the number of the small‐diameter, smooth‐walled parabronchi (PR) was considerably increased. On the 9th ED, anastomosing of the developing parabronchi was observed forming large diameter ones and the open‐type endocrine cells in the parabronchial wall were observed. On the 10th ED, deep costal impressions on the lung tissue were seen, the atrial primordia could be observed and the primordia of all air sac were developed. In conclusion; morphogenesis and differentiation of the developing lung epithelium depend on epithelial‐mesenchyme interaction.
The Block Bootstrap for Parameter Estimation Error In Recursive Estimation Schemes, With Applications to Predictive Evaluation

This paper introduces a new block bootstrap which is valid for recursive m-estimators, in the sense that its use suFFIces to mimic the limiting distribution of (1/P^.5)(SUM(t=R to T-1)(THETA-t-hat - THETA-plus)); where R denotes the length of the estimation period, P the number of recursively estimated parameters, bµt is a recursive miestimator constructed using the first t observations, and THETA-t-plus is its probability limit. In the recursive case, earlier observations are used more frequently than temporally subsequent observations. This introduces a bias to the usual block bootstrap. We circumvent this problem by first resampling R observations from the initial R sample observations, and then concatenating onto this vector an additional P resampled observations from the remaining sample. Thereafter, THETA-hat-t-star is constructed using the resampled series, and an adjustment term is added to 1/P^. 5)(SUM(t=R to T-1)(THETA-hat-t-star - THETA-t-hat)); in order to ensure that the distribution of this sum is the same as the distribution of (1/P^.5)(SUM(t=R to T-1)(THETA-t-hat - THETA-plus)). This parameter estimation error bootstrap for recursive estimation schemes can be used to provide valid critical values in a variety of interesting testing contexts, and three such leading applications are developed. The first is a generalization of the reality check test of White (2000) that allows for non vanishing parameter estimation error. The second is an out-of-sample version of the integrated conditional moment (ICM) test of Bierens (1982,1990) and Bierens and Ploberger (1997) which provides out of sample tests consistent against generic (nonlinear) alternatives. Finally, the third is a procedure assessing the relative out-of-sample predictive accuracy of multiple conditional distribution models. This procedure is based on an extension of the Andrews (1997) conditional Kolmogorov test. The main findings from a small Monte Carlo experiment indicate that: (i) the adjustment term used in the suggested bootstrap substantially improve coverage rates relative to a bootstrap without adjustment, and (ii) the suggested bootstrap is as reliable as the standard block bootstrap within the context of full sample estimation.
Expression and Role of TRIM2 in Human Diseases

Tripartite motif (TRIM) protein family proteins contain more than 80 members in humans, and most of these proteins exhibit E3 ubiquitin ligase activity mediated through a RING finger domain. Their biological functions are very complex, and they perform diverse functions in cell evolution processes, such as intracellular signaling, development, apoptosis, protein quality control, innate immunity, autophagy, and carcinogenesis. Tripartite motif-containing protein 2 (TRIM2), a member of the TRIM superfamily, is an 81 kDa multidomain protein, also known as CMT2R or RNF86, located at 4q31.3. TRIM2 functions as an E3 ubiquitin ligase. Current studies have shown that TRIM2 can play roles in neuroprotection, neuronal rapid ischemic tolerance, antiviral responses, neurological diseases, etc. Moreover, based on some studies in tumors, TRIM2 regulates tumor proliferation, migration, invasion, apoptosis, and drug resistance through different mechanisms and plays a critical role in tumor occurrence and development. This review is aimed at providing a systematic and comprehensive summary of research on TRIM2 and at exploring the potential role of TRIM2 as a biomarker and therapeutic target in many kinds of human diseases.
Female Rural–Urban Migrants and Online Marketplaces in Emerging Economies: Evidence from Thailand and Viet Nam

This research aimed to examine the factors affecting the participation of female rural–urban migrants in online marketplaces, and the welfare gains and their distribution from their participation. Our analysis was based on a unique data set of rural households, villages, and rural–urban migrants in Thailand and Viet Nam. Online market participation is classified into three activities: financial transaction; trading; and business. We accounted for the endogeneity issue of online market participation in welfare impact assessment by using an instrumental variable approach. Our results show that the participation has a positive effect on the consumption of female migrants only when they participate in the complete bundle of online market activities. In addition, we also find that the poor benefit insignificantly from online marketplaces. This raises a concern regarding increasing welfare inequality and suggests that the poor should be supported in order not to be left behind.
Persuasive strategy implementation choices and their effectiveness: towards personalised persuasive systems

ABSTRACT Persuasive systems motivate behaviour change using persuasive strategies (PS) which are often implemented in various ways. However, whether or not the effectiveness of PS varies depending on implementation choices is yet to be investigated via an empirical study. We conduct a large-scale study of 568 participants to investigate if and how individuals at different Stages of Change (SoC) respond to different implementations of each strategy in the same system. We also explore why the implementations motivate behaviour change using ARCS motivation model. Our results show that people’s SoC plays a significant role in the perceived effectiveness of different implementations of the same strategy and that the implementations motivate for different reasons. For instance, people at the precontemplation stage are motivated by reward strategy implemented as badges because it increases their Confidence, while people in the preparation stage prefer reward implemented as points to build their Confidence. Our work links SoC theory with motivation theory and Persuasive Systems Design (PSD) model to offer practical guidelines for tailoring PS implementations to individuals to motivate behaviour change.
SICL-Fed Balanced Antipodal Dipole Antenna With Wideband Operation and Cross-Polarization Improvement at Millimeter-Wave Band

A substrate integrated coaxial line-fed balanced antipodal dipole antenna array is proposed for millimeter-wave (MMW) applications in this letter. Different from the traditional dual-armed dipole antenna, a balanced antipodal dipole element with three arms is proposed to improve the cross-polarization level by canceling the vertically polarized electric-field components. A cross-polarization level of less than −20 dB is achieved over the entire frequency band. Meanwhile, a gap is etched on each dipole arm to achieve dual-mode operation and broaden the impedance bandwidth of the dipole element, and an impedance bandwidth of more than 65% is obtained. By combining the proposed dipole elements with the unequal feeding network, a 1 × 8 dipole antenna array is designed, fabricated, and measured. The measured results show that the proposed dipole antenna array can achieve a wide −10 dB impedance bandwidth of more than 54% from 24.5 to 43 GHz, a sidelobe level of low than −18 dB in E-plane, and a cross-polarization level of low than −20 dB. With the merits of wide operating bandwidth, low cross-polarization level, low sidelobe level, low profile, and easy integration, the proposed antenna array is valuable to advanced MMW communication systems.
Comparative Analysis of Online Student Engagement across Gender

Student engagement is an important component to learning. It has shown a connection to higher academic achievements among students who are more engaged. Student engagement in collaborative writing is required to ensure the success of the group in achieving the goal. However, due to Covid-19 circumstances, collaborative writing projects among the academic writing students had to be carried out online. The objectives of this study are to assess the overall student engagement in online collaborative writing projects, and investigate the differences in their responses based on gender. Male and female student engagement was found to be more influenced by participation attribute, followed by performance, emotions and skills. Female students’ way to participate was by engaging in online conversation, while male students prefer to get to know their team members. Both groups, however, did not prefer to make regular post on online forums. Future research is suggested to include peer evaluation as a method to verify online student engagement in collaborative writing projects.
BUILDING INFORMATION MODELLING AND PROJECT INFORMATION MANAGEMENT FRAMEWORK FOR CONSTRUCTION PROJECTS

The study aims to develop an effective BIM-project information management framework (BIM-PIMF) and associated assessment model for construction projects with a view to enhancing the functional management of project information. An explanatory case study technique and case study evidence from four BIM construction projects form the study’s research design. The study identified and established the three sub-criteria of the BIM-PIMF model which are the BIM process level factors, BIM product level factors, and the key indicators for a successful BIM deployment on construction project sites. These criterias were semantically linked to the development of the BIM-PIMF framework on a five-point metric scale. The deliverables of this study include the development of the BIM-PIMF framework, together with its analytical scoring system. The findings of the study will improve the information channels of and ease the integration of technological innovations in construction processes while improving the technical competencies of project staff. The study highlighted a basket of effective recommendations and strategies to enhance the deployment of BIM throughout a project lifecycle. Policymakers and government departments can utilize the model in assessing the level of usage of BIM in a construction project as one of the useful measures in gauging which construction firms to be provided subsidies.
Healthcare-Associated SARS-CoV-2 Reinfection after 3 Months with a Phylogenetically Distinct Omicron Variant: A Case Report

This case report describes a 60-year-old female patient suffering from systemic sclerosis, for which she received immunomodulatory drugs. Her first SARS-CoV-2-positive nasopharyngeal sample was obtained in the emergency department, on 31 January 2022. Whole genome sequencing confirmed infection with Omicron BA.1. 1. Her hospital stay was long and punctuated by many complications, including admission to the intensive care unit. At the beginning of April 2022, she started complaining of increased coughing, for which another SARS-CoV-2 RT-qPCR test was performed. The latter nasopharyngeal swab showed a strongly positive result. To support the theory of healthcare-associated reinfection, whole genome sequencing was performed and confirmed reinfection with Omicron BA.2. Since this patient was one of ten positive cases in this particular ward, a hospital outbreak investigation was performed. Whole genome sequencing data were available for five of these ten patients and showed a cluster of four patients with ≤2 small nucleotide polymorphisms difference.
A critique of length and bias dependent constraints for 1T-DRAM operation through RFET

Capacitorless dynamic memory (one transistor dynamic random access memory (1T-DRAM)) operation in a reconfigurable field effect transistor (RFET) is critically governed by different lengths associated with the architecture. These lengths consisting of ungated region (L UG), control gate (L CG), polarity gate (L PG), storage region length (L S), and total length (L T) can be sensitive to the fabrication process, and hence, critical for 1T-DRAM. This work presents an insightful critique of the above mentioned lengths for realising optimal 1T-DRAM performance. It is shown that RFET with highest values of L S/L T and L CG/L T shows good short channel immunity but does not necessarily ensure enhanced 1T-DRAM metrics. Results indicate that for a fixed L T, retention time can vary over a wide range (550 ms to 8.7 s) depending on the values of L S/L T and L CG/L T, and hence, appropriate optimization is imperative. The work contributes towards better understanding and optimizing L CG/L T to ensure improved 1T-DRAM metrics in terms of enhanced retention (>64 ms), acceptable sense margin (>6 µA µm−1), current ratio (>104) with low values of read (2 ns) and write (1 ns) time to further extend multi-functional facets of nanoscale RFETs for memory applications. In addition, the effect of traps, process sensitivity, reduced number of voltage levels, and disturbance caused by shared word line (WL)/bit line (BL) are also analysed in this work. Results indicate that state ‘0’ of the cell sharing BL with the selected cell is strongly affected by BL disturbance. WL disturbance primarily impacts state ‘1’ of the cell sharing WL with selected cell (only for write 1 and read operations).
