AbstractThe suitability of Ba2MgWO6 (BMW) double perovskite doped with Eu3+ for the construction of an optical thermometer was tested. It has been shown that by controlling the conditions of BMW synthesis, the sensitivity of the optical thermometer and the useful range of its work can be changed. Pure BMW and doped with Eu3+ samples were prepared using the mechano-chemical and co-precipitation methods. Both the absolute sensitivity and the relative sensitivity in relation to the synthesis route were estimated. The findings proved that the relative sensitivity can be modulated from 1.17%K−1 at 248 K, to 1.5%K−1 at 120 K for the co-precipitation and the mechanochemical samples, respectively. These spectacular results confirm the applicability of the Ba2MgWO6: Eu3+ for the novel luminescent sensors in high-precision temperature detection devices. The density-functional theory was applied to elucidate the origin of the host emission.

AbstractDespite great advances in describing Bordetella pertussis infection, the role of the host microbiota in pertussis pathogenesis remains unexplored. Indeed, the microbiota plays important role in defending against bacterial and viral respiratory infections. We investigated the nasopharyngeal microbiota in infants infected by B. pertussis (Bp), Rhinovirus (Rv) and simultaneously by both infectious agents (Bp + Rv). We demonstrated a specific nasopharyngeal microbiome profiles for Bp group, compared to Rv and Bp + Rv groups, and a reduction of microbial richness during coinfection compared to the single infections. The comparison amongst the three groups showed the increase of Alcaligenaceae and Achromobacter in Bp and Moraxellaceae and Moraxella in Rv group. Furthermore, correlation analysis between patients’ features and nasopharyngeal microbiota profile highlighted a link between delivery and feeding modality, antibiotic administration and B. pertussis infection. A model classification demonstrated a microbiota fingerprinting specific of Bp and Rv infections. In conclusion, external factors since the first moments of life contribute to the alteration of nasopharyngeal microbiota, indeed increasing the susceptibility of the host to the pathogens' infections. When the infection is triggered, the presence of infectious agents modifies the microbiota favoring the overgrowth of commensal bacteria that turn in pathobionts, hence contributing to the disease severity.

Published: November 2021

AbstractComposite rocks are easily encountered in a wide range of geotechnical construction projects. Understanding their mechanical properties and failure modes is very important to ensure project quality and safety. This study conducted a mechanical analysis to assess the stress distribution in composite rock with a horizontal interlayer and predicted the possible failure modes. Uniaxial compression tests were carried out on the composite rock samples to reveal their mechanical properties. It was concluded that a composite rock with a thick interlayer failed more easily than a composite rock with a thin interlayer. Four potential failure modes were related to the internal stress distribution under compression and the differences in deformation capacity and strength among the constituent components. The stress distribution derived from the mechanical analysis could explain the failure mechanism very well. These results verified the validity of the mechanical analysis results and improved understanding of the mechanical properties of composite rock with a horizontal interlayer.

Published: November 2021

AbstractThough asthma and bronchiectasis are two different diseases, their coexistence has been demonstrated in many patients. The aim of the present study is to compare the characteristics of asthmatic patients with and without bronchiectasis and to assess risk factors for the development of this condition. Two hundred and twenty-four moderate-severe asthmatic patients were included. The severity of bronchiectasis was assessed by Reiff and FACED parameters. Logistic regression was used to identify independent factors associated with bronchiectasis. Bronchiectasis was identified in 78 asthma patients. In severe asthma patients, its prevalence was 56.9%. Bronchiectasis was defined as mild in81% of patients using modified Reiff criteria and in 74% using FACED criteria. Asthmatic patients with bronchiectasis had decreasing FEV1, FVC and FEV1/FVC (p = 0.002, 0.005 and 0.014 respectively), presented more frequent asthma exacerbations (p < 0.001) and worse asthma control (ACT 21 vs 16pts, p < 0.001). Factors independently associated with bronchiectasis were older age (42–65 years: OR, 3.99; 95% CI 1.60 to 9.95, P = 0.003; ≥ 65 years: OR, 2.91; 95% CI 1.06 to 8.04, P = 0.039), severe asthma grade (OR, 8.91; 95% CI 3.69 to 21.49; P < 0.001) and frequency of asthma exacerbations (OR, 4.43; 95% CI 1.78 to 11.05; P < 0.001). In patients with severe asthma, age of asthma onset (OR, 1.02; 95% CI 1.01 to 1.04; P = 0.015) and asthma exacerbations (OR, 4.88; 95% CI 1.98 to 12.03; P = 0.001) were independently associated with the development of bronchiectasis. The prevalence of bronchiectasis in severe asthmatic patients is high. Age of asthma onset and exacerbations were independent factors associated with the occurrence of bronchiectasis.

AbstractWe investigated the chemical pressure effects on structural and electronic properties of SnTe-based material using partial substitution of Sn by Ag0.5Bi0.5, which results in lattice shrinkage. For Sn1−2x(AgBi)xTe, single-phase polycrystalline samples were obtained with a wide range of x. On the basis of band calculations, we confirmed that the Sn1−2x(AgBi)xTe system is basically possessing band inversion and topologically preserved electronic states. To explore new superconducting phases related to the topological electronic states, we investigated the In-doping effects on structural and superconducting properties for x = 0.33 (AgSnBiTe3). For (AgSnBi)(1−y)/3InyTe, single-phase polycrystalline samples were obtained for y = 0–0.5 by high-pressure synthesis. Superconductivity was observed for y = 0.2–0.5. For y = 0.4, the transition temperature estimated from zero-resistivity state was 2.4 K, and the specific heat investigation confirmed the emergence of bulk superconductivity. Because the presence of band inversion was theoretically predicted, and the parameters obtained from specific heat analyses were comparable to In-doped SnTe, we expect that the (AgSnBi)(1−y)/3InyTe and other (Ag, In, Sn, Bi)Te phases are candidate systems for studying topological superconductivity.

AbstractRecently, pathological changes in the fat pad on the anterior inferior iliac spine (AIIS), between the proximal rectus femoris and joint capsule, have been highlighted as a cause of anterior hip pain. However, precise fat pad features, such as the spatial distribution distal to the AIIS, histological features, and in vivo tissue elasticity, remain unclear. This study aimed to investigate the morphological characteristics of the fat pad on the AIIS. Four hips from four cadaveric donors were both macroscopically and histologically investigated, and eight hips from four volunteers were assessed using ultrasonography. The fat pad on the AIIS was also surrounded by the iliopsoas and gluteus minimus, extending distally to the superficial portion of the vastus lateralis, and the anterior portion of the gluteus maximus tendon. Histological analysis revealed that the fat pad was composed of loose connective tissue. Based on the ultrasonography, the shear wave velocity in the fat pad was significantly lower than that in the joint capsule. Conclusively, the pathological adhesion between the joint capsule and pericapsular muscles, if caused by fat pad fibrosis, may occur following the abovementioned fat pad spatial distribution.

AbstractOmbrotrophic peatlands are a globally important carbon store and depend on atmospheric nutrient deposition to balance ecosystem productivity and microbial decomposition. Human activities have increased atmospheric nutrient fluxes, but the impacts of variability in phosphorus supply on carbon sequestration in ombrotrophic peatlands are unclear. Here, we synthesise phosphorus, nitrogen and carbon stoichiometric data in the surface and deeper layers of mid-latitude Sphagnum-dominated peatlands across Europe, North America and Chile. We find that long-term elevated phosphorus deposition and accumulation strongly correlate with increased organic matter decomposition and lower carbon accumulation in the catotelm. This contrasts with literature that finds short-term increases in phosphorus supply stimulates rapid carbon accumulation, suggesting phosphorus deposition imposes a threshold effect on net ecosystem productivity and carbon burial. We suggest phosphorus supply is an important, but overlooked, factor governing long-term carbon storage in ombrotrophic peatlands, raising the prospect that post-industrial phosphorus deposition may degrade this carbon sink.
The Complex Role of Utterance Length on Grammaticality: Multivariate Multilevel Analysis of English and Spanish Utterances of First-Grade English Learners
Authors: Castilla-Earls Anny , Francis David J. , Iglesias Aquiles 
Published: November 2021

Purpose:
This study examined the relationship between utterance length, syntactic complexity, and the probability of making an error at the utterance level.

Method:
The participants in this study included 830 Spanish-speaking first graders who were learning English at school. Story retells in both Spanish and English were collected from all children. Generalized mixed linear models were used to examine within-child and between-children effects of utterance length and subordination on the probability of making an error at the utterance level.

Results:
The relationship between utterance length and grammaticality was found to differ by error type (omission vs. commission), language (Spanish vs. English), and level of analysis (within-child vs. between-children). For errors of commission, the probability of making an error increased as a child produced utterances that were longer relative to their average utterance length (within-child effect). Contrastively, for errors of omission, the probability of making an error decreased when a child produced utterances that were longer relative to their average utterance length (within-child effect). In English, a child who produced utterances that were, on average, longer than the average utterance length for all children produced more errors of commission and fewer errors of omission (between-children effect). This between-children effect was similar in Spanish for errors of commission but nonsignificant for errors of omission. For both error types, the within-child effects of utterance length were moderated by the use of subordination.

Conclusion:
The relationship between utterance length and grammaticality is complex and varies by error type, language, and whether the frame of reference is the child's own language (within-child effect) or the language of other children (between-children effect).

Family Environmental Dynamics Differentially Influence Spoken Language Development in Children With and Without Hearing Loss
Authors: Holt Rachael Frush , Kronenberger William G. , Pisoni David B. 
Published: November 2021

Purpose:
The aim of this study was to evaluate whether families of children with sensorineural hearing loss (SNHL) are organized similarly to those of typically developing, typically hearing (TH) children and whether the dimensions of family dynamics and environment are related to spoken language development similarly in children with and without SNHL.

Method:

Primary caregivers of children with SNHL (
n
= 63) or TH (
n
= 65) completed the Family Environment Scale–Fourth Edition (FES-4) to assess multiple dimensions of family environment. Children's receptive vocabulary was assessed with the Peabody Picture Vocabulary Test–Fourth Edition, and their receptive language was assessed by an age-appropriate version of the Concepts and Following Directions subtest of the Clinical Evaluation of Language Fundamentals and the Sentence Comprehension subscale of the Comprehensive Assessment of Spoken Language–Second Edition. Principal component analysis was used to examine the dimensional structure of the family environment.

Results:
Three higher order components were derived from FES-4 subscales for both families of children with SNHL and with TH: Supportive, Controlling, and Conflicted. However, the composition of the factors themselves differed between the two groups. For the TH group, most family environment measures on the FES-4 were not associated with language outcomes. In contrast, for children with SNHL, families who were more supportive, less controlling, and less conflicted had children with better language skills.

Conclusions:
Three well-accepted dimensions of family dynamics and functioning apply to families of children with SNHL, but their composition differs from those of families with TH children. Family environmental dynamics were much more strongly associated with language outcomes in children with SNHL than in their TH peers. The spoken language development of children with SNHL, in particular, is better in families that provide high levels of support for each other and, in particular, low levels of control, disorganization, and conflict, reflecting the fragile nature of their spoken language development.
Facial skin colour classification using machine learning and hyperspectral imaging data
Authors: Zhu Wanshan , Sang Peng , He Yifan 
Published: November 2021

AbstractFacial skin colour is a primary indicator of human health, and skin care products aim to improve it. However, the beauty industry lacks accurate methods to automatically classify skin colour because it uses high granularity labels such as the Pantone scale, with up to 110 facial skin‐colour types. In this study, the automatic classification of facial skin colour based on hyperspectral imaging and machine learning is investigated. An experiment is conducted using hyperspectral imaging to collect multi‐dimensional big data on most of these skin‐colour types. Owing to the multi‐dimensionality of the data and the high granularity of skin‐colour types, classifying the colour type accurately is challenging. Nevertheless, various machine‐learning methods are applied and it is found that each had an advantage in categorizing a subset of colour types. Further, the features of the data are analysed and it is found that skin chromaticity and brightness could be classified separately to provide valuable information. Finally, to utilise this information and combine the advantages of various machine‐learning methods, a two‐stage integrated classifier is developed, which achieved 90.4% accuracy. This classifier can be used by the beauty industry to evaluate the effect of skincare products on facial skin colour.

Authors: Liu Qing , Liu Qikun , Li Jianbin , Wei Jinjin , Zhang Dewei 
Published: November 2021

AbstractThis paper proposes three balanced multiple‐layer dual‐mode substrate integrated waveguide (SIW) bandpass filters. The first balanced filter has two substrate layers, and two pairs of balanced feeding ports are located on the upper substrate layer. The lower and upper dual‐mode SIW cavities are coupled by two crossed slots in the middle metal layer. The second balanced filter has two substrate layers, and two pairs of balanced feeding ports locate parallelly on the upper and lower substrate layers, respectively. The third balanced filter has three substrate layers, and two pairs of balanced feeding ports locate vertically on the upper and lower substrate layers, respectively. The proposed three balanced filters can produce three, two and one finite‐transmission zeros (FTZs), respectively. Characteristics of the proposed multiple‐layer SIW filters with controllable FTZs' locations are analysed in detail. For the demonstration, some design examples with the centre frequency of 7.5 GHz and bandwidth of 240 MHz are presented, and three design examples are fabricated to verify the performance of the proposed balanced filters. The measured results agree well with simulated ones.
Development of a current source resonant inverter for high current MHz induction heating
Authors: Aunsborg Thore S. , Duun Sune Bro , Munk‐Nielsen Stig , Uhrenfeldt Christian 
Published: November 2021

AbstractHigh frequency industrial induction heating processes typically employ resonant inverters to reach high efficiency at high power levels. Advancements in wide band gap (WBG) device technology has made it feasible to push the possible frequency of these processes into the MHz regime using solid state technology. Several topologies can be applied, each with advantages and drawbacks. This paper presents a current source resonant inverter (CSRI) employing a custom designed power module utilizing 1700V SiC MOSFETs for MHz operation of a high‐Q resonant tank for induction heating, which presents new challenges in the inverter module design. An integrated gate driver structure is demonstrated driving four MOSFETs in parallel in MHz operation. Theoretical analysis predicts substantial parasitic influence on inverter operation, and thus an inverter is constructed to provide experimental verification of MHz operation, while the challenges associated with high frequency CSRI operation are discussed. In the experimental inverter setup, the fabricated power module achieves efficiency for a calculated reactive power of 170 kVA and 2.3 kW output power during unloaded operation, validating the inverter design for extension to higher power loaded operation.

Published: November 2021

Aims.We present the first release of Turin-SyCAT, a multifrequency catalog of Seyfert galaxies.Methods.We selected Seyfert galaxies considering criteria based on radio, infrared, and optical properties and starting from sources belonging to hard X-ray catalogs and surveys. We visually inspected optical spectra available for all selected sources. We adopted homogeneous and stringent criteria in the source selection aiming at reducing the possible contamination from other source classes.Results.Our final catalog includes 351 Seyfert galaxies distinguished in 233 type 1 and 118 type 2. Type 1 Seyfert galaxies appear to have mid-IR colors similar to blazars, but are distinguished from them by their radio-loudness. Additionally, Seyfert 2 galaxies have mid-IR colors more similar to quasars than BL Lac objects. As expected from their spectral properties, type 1 and 2 Seyfert galaxies show a clear distinction when using theu − rcolor. Finally, we found a tight correlation between the mid-IR fluxes at both 12 and 22 μm (i.e.,F12andF22, respectively) and hard X-ray fluxes between 15 and 150 keV. Both Seyfert types appear to follow the same trend and share similar values of the ratios ofF12andF22toFHXin agreement with expectations of the AGN unification scenario.Conclusions.As future perspectives, the Turin-SyCAT will then be used to search for heavily obscured Seyfert galaxies among unidentified hard X-ray sources, given the correlation between mid-IR and hard X-rays, and to investigate their large-scale environments.

Salt is an essential mineral to our health that, in its sodium form, is involved in many functional processes in human body. Excessive salt consumption increases the risk of high blood pressure and cardiovascular disease (CVD). The World Health Organization (WHO) and the United Nations (UN) have identified salt reduction as one of the most cost-effective strategies to prevent the spread of non-communicable diseases. The objectives of the present study is to determine the salt status in the Moroccan population based on 24-hour dietary recall and food frequency.
This descriptive cross-sectional study was conducted on 133 children and adolescents recruited from public schools in Rabat regions. The average total salt intake status was assessed by 24 h dietary recall. Food frequency questionnaire was used to evaluate children’s nutritional habits and the consumption of food rich in salt.
The average total salt intake is 5264.5±2398.6mg/day. The knowledge of the study population on the health risks of excess salt, 81% of participants stated that high salt consumption is positively associated with health risks, while only 7% confirmed that there is no relationship between excess salt and health problems. For the use of iodized salt, about half (46.6%) of the study population uses iodized salt. For each variable, a significant difference is shown between the subgroups (p<0.001).
The current intake of salt is very high in both children and adults. Reducing salt intake is one of the most cost-effective measures to prevent CVD. A low-salt diet during childhood can prevent the development of CVD and hypertension later in life. However, there is no strategy to keep children and adults low in salt.
