AbstractAll‐inorganic perovskite quantum dots (QDs) have emerged as a new category of low‐cost semiconducting luminescent materials for optoelectronic applications. However, their poor stability has become the main challenge that impedes their potential applications. Herein, Ni‐doped CsPbBr3 QDs with lead phosphate (Pb3(PO4)2) shell through surface sacrificial coating (c‐Ni‐CsPbBr3) have been developed based on a modified thermal injection approach. The synergistic effect of Ni doping and Pb3(PO4)2 coating effectively improves the stability and optical performances of CsPbBr3 QDs, including photoluminescence (PL) intensity, the average lifetime, and PL quantum yield (QY). Thus, the c‐Ni‐CsPbBr3 QDs demonstrate the full width at half maxima (FWHM) and PLQY being 18.42 nm and 90.77%, respectively. The PL intensity of c‐Ni‐CsPbBr3 can be maintained at 81% of its original value after being heated at 100 °C for 1 h. No phase transformation can be observed after being stored under ambient conditions (25 °C, 60% relative humidity (RH)) for 21 days. In addition, by combining green c‐Ni‐CsPbBr3 QDs, red CdSe‐based QDs and the blue GaN chip, a QD enhancement film (QDEF) is fabricated to form a liquid crystal display (LCD) backlit with a wide color gamut covering cover 121% of the National Television System Committee (NTSC) standard.
Current status of IBD and surgery of Crohn's disease in Thailand
Authors: Riansuwan Woramin , Limsrivilai Julajak 
Published: May 2021

AbstractInflammatory bowel disease (IBD) consists of two diseases: ulcerative colitis (UC) and Crohn's disease (CD). The incidence of IBD is much higher in Western countries compared to Asian countries, especially in Thailand. The incidence of UC in Thailand is quite low and seems less aggressive than in Western countries. Over the past two decades, the evolution of UC management in Thailand has led to a reduction in hospitalization and colectomy rate. Regarding CD, the majority of patients have an inflammatory phenotype at diagnosis. Diagnosis of CD remains challenging in Thailand as the time from onset of symptoms to diagnosis is quite delayed, possibly due to unawareness and difficulty in the differential diagnosis between CD and other infectious entero‐colitis such as intestinal tuberculosis. With a significant trend to early initiation of immunomodulators and biologics, the cumulative rate of surgery after diagnosis has been improved. To improve the outcomes of CD treatment in Thailand, physicians need more awareness to recognize the disease, which results in early diagnosis, prevention of long‐term complications, and reduction in the rate of surgery.

AbstractBackgroundThis article reports the results of a rapid scoping review of the literature on COVID‐19 transmission risk to workers in essential sectors such as retail, health care, manufacturing, and agriculture, and more particularly the experiences of workers in precarious employment and social situations.MethodsFollowing scoping review methods, we included 30 studies that varied in terms of methodology and theoretical approaches. The search included peer‐reviewed articles and grey literature published between March and September 2020.ResultsBased on the studies reviewed, we found that COVID‐19 infection and death rates increased not only with age and comorbidities, but also with discrimination and structural inequities based on racism and sexism. Racial and ethnic minority workers, including migrant workers, are concentrated in high‐risk occupations and this concentration is correlated to lower socioeconomic conditions. The COVID‐19 pandemic appears in the occupational health and safety spotlight as an exacerbator of already existing socioeconomic inequalities and social inequalities in health, especially in light of the intersection of issues related to racism, ethnic minority status, and sexism.ConclusionsThis review provides early evidence about the limitations of institutions' responses to the pandemic, and their capacity to provide a safe and decent working environment for all workers, regardless of their employment status or the social protections they may enjoy under normal circumstances. It is also important to think about these issues in the postpandemic context, when conditions of precariousness and vulnerability persist and possibly worsen.

AbstractTCF7L2 encodes transcription factor 7‐like 2 (OMIM 602228), a key mediator of the evolutionary conserved canonical Wnt signaling pathway. Although several large‐scale sequencing studies have implicated TCF7L2 in intellectual disability and autism, both the genetic mechanism and clinical phenotype have remained incompletely characterized. We present here a comprehensive genetic and phenotypic description of 11 individuals who have been identified to carry de novo variants in TCF7L2, both truncating and missense. Missense variation is clustered in or near a high mobility group box domain, involving this region in these variants' pathogenicity. All affected individuals present with developmental delays in childhood, but most ultimately achieved normal intelligence or had only mild intellectual disability. Myopia was present in approximately half of the individuals, and some individuals also possessed dysmorphic craniofacial features, orthopedic abnormalities, or neuropsychiatric comorbidities including autism and attention‐deficit/hyperactivity disorder (ADHD). We thus present an initial clinical and genotypic spectrum associated with variation in TCF7L2, which will be important in informing both medical management and future research.

AbstractCHARGE syndrome is a genetic disorder that affects multiple organ and sensory systems. Cranial nerve involvement is one of the key clinical diagnostic criteria. We present the case of an 8‐year‐old girl with CHARGE syndrome, associated right‐sided facial palsy, and chronic severe migraines, that were intractable to medical treatment. At age 6, onabotulinum toxin A was used to weaken the contralateral non‐paralyzed side of her face to address her stigmatizing asymmetry. Onabotulinum toxin A chemodenervation was performed on the left lower lip depressors to relax the muscles and improve left lower lip position. Coincidentally, it was noted that with these treatments, migraine symptoms resolved. As the chemodenervation subsided over the next 3–4 months, the severe migraines returned. Continued treatment with onabotulinum toxin A injections every 3 months has resulted in ongoing improvements in facial symmetry and migraine control. Onabotulinum toxin A is a well‐known treatment of chronic migraine. Injections are usually directed to the occipitalis, frontalis, and corrugator muscles. The literature has no reports of injections to the lower lip depressors as a useful therapy for migraine, making the results from this case unique.

AbstractIntroductionPrior research suggests that the strength of association between Alzheimer's disease (AD) pathology and lower cognitive performance is influenced by modifiable psychosocial factors, such as social network size. However, little is known about distinct social relationship types.MethodsThe current cross‐sectional study used data from the Washington Heights‐Inwood Columbia Aging Project to examine whether social network characteristics (i.e., total size, spouse/partner, number of children, other relatives, friends) moderate associations between cortical thickness in regions implicated in AD and cognitive performance.ResultsLower cortical thickness was associated with worse global cognition among individuals with smaller friend networks, but not among individuals with larger friend networks. This pattern of results was most prominent for language and speed/executive functioning.DiscussionLongitudinal and intervention studies are needed to determine whether these cross‐sectional findings reflect a protective effect of later‐life friendships for maintaining cognitive performance in the context of poorer brain health.
Enhanced swelling using photothermal responsive surface‐immobilized microgels
Authors: Ou Charly , Wang Chang‐Sheng , Giasson Suzanne 
Published: May 2021

AbstractUnprecedented quantitative assessment of the swelling behavior of surface‐immobilized photothermal responsive microgels (PTRM) is reported. The PTRM were prepared by incorporating plasmonic gold nanoparticles (AuNPs) in thermo‐responsive cationic microgels based on poly(N‐isopropylacrylamide) (BM). The stimuli‐responsive behavior of the microgels was investigated in aqueous suspensions using Dynamic Light Scattering (DLS) and on surfaces using a Quartz Crystal Microbalance with Dissipation (QCM‐D) as well as with the Surface Forces Apparatus (SFA). Both the BM and PTRM in aqueous suspensions underwent a similar temperature‐induced volume phase transition at around 35°C. The complexation of AuNPs with the BM led to a decrease in the surface charge allowing to increase the surface grafting density. This favored a unidirectional upward swelling of the surface immobilized PTRM. The study reports significant photo‐triggered swelling responses on surface with decreases in film thickness up to 82%.
Modernisierung U‐Bahnhof Sendlinger Tor

AbstractRund 250.000 Fahrgäste/d und 13 kreuzende U‐Bahn‐, Tram‐ und Buslinien machen die Station Sendlinger Tor zu einem der wichtigsten Verkehrsknotenpunkte im Münchner Nahverkehrsnetz. Die 1971 eröffnete Station wird aktuell umfassend erneuert und zu einem modernen Zukunftsbahnhof umgestaltet. Ziel der Maßnahmen ist es, die Leistungsfähigkeit und Sicherheit für Fahrgäste zu erhöhen – denn das heutige Fahrgastaufkommen bringt den Bahnhof an seine Kapazitätsgrenze. Täglich bilden sich lange Staus der Fahrgäste an den zentralen Treppenanlagen. Insbesondere ist auch im Falle eines Brands zu befürchten, dass die knappen Treppenkapazitäten im Bestand zu langen Entfluchtungszeiten führen. Zentrale Maßnahmen sind daher die Erweiterung des Bauwerks, die Neugestaltung der Durchgänge sowie die Verbreiterung der bestehenden Ausgänge und die Verlängerung der Lifte an die Oberfläche. Gleichzeitig werden bei notwendigen Sanierungsarbeiten die Schäden an Betonsubstanz und Bauwerksfugen, die in den letzten 50 Jahren durch Feuchtigkeit und Streusalz entstanden sind, behoben. Das Konzept zur gestalterischen Erneuerung ging aus einem europaweiten Planungswettbewerb hervor. Im Ergebnis erhält der Bahnhof eine kräftige Farbgebung, die auf den beiden Bahnsteigebenen die ursprünglichen Farben aufgreift, der Verteilerebene eine moderne aufgeräumte Optik verleiht und die Ausgangsbereiche akzentuiert. Modernisiert wird auch die gesamte technische Ausrüstung des Bahnhofs. Dies geschieht wie der gesamte Umbau unter laufendem Betrieb. Entstehen wird ein moderner, barrierefreier U‐Bahnhof mit attraktivem Erscheinungsbild und höchsten Sicherheitsstandards. Zentrale Herausforderung sind neben den technischen Aspekten die extrem beengten Platzverhältnisse sowie das Bauen im Bestand mit möglichst geringen Einschränkungen für sämtliche Verkehrsteilnehmer.
Enhancing environmental information transparency through corporate social responsibility reporting regulation

Published: May 2021

AbstractThis research aims to contribute to the scientific debate about the lack of interlinkages between mandatory non‐financial reporting and sustainable business models. For our purposes, a counter‐accounting analysis was conducted on the non‐financial reports of a sample of 145 Italian firms interested by the Directive 2014/95/EU effects. Specifically, the study adopts an empirical approach to evaluate environmental information transparency, which represents one of the main critical issues concerning the non‐financial declarations prepared by European Italian Public Interest Entities (PIEs) to comply with Directive 2014/95/EU. The results highlight that corporate governance and report characteristics affect environmental transparency. Furthermore, the results confirm the overall attitude to avoid the disclosure of unfavourable or unavailable environmental information through impression management strategies. Finally, the analysis underlines the opportunities for policymakers to rethink mandatory non‐financial reporting to sustain the ecological transition of European PIEs.
Computed tomography study of the relationship between pelvic incidence and bony contribution to lumbar lordosis in children
Authors: Baker Joseph F. 
Published: May 2021

AbstractThere is little data regarding the relationship in children and how it may change with aging. The aim of this radiographic study was to define the relationship between pelvic incidence (PI) and segmental vertebral body lordosis through childhood. In 150 children, CT scans of the lumbar spine and pelvis were analyzed measuring PI, sacral table angle (STA), sacral kyphosis (SK), and segmental lordosis (SL) individually L1–L5. Children were grouped by age: (1) 0–60 months; (2) 61–120 months; (3) 121–185 months. Mean PI for the entire cohort was 40.4, mean SL for L1–0.6, L2 0.0, L3 1.8, L4, 4.7, and L5 11.4. There were 40 children in Group 1, 63 in Group 2 and 37 in Group 3. SL differed between age groups at all levels except at L2. L1 and L2 became more kyphotic with increasing age; L3, L4, and L5 became more lordotic with increasing age. The correlation between PI and SL at each level became stronger with increasing age. Similarly, the correlation between PI and STA and between PI and SK also became stronger with increasing age. As children mature, the relationship between PI and segmental lordosis at each level of the lumbar spine becomes stronger—the relationship between PI and lordosis trends toward that seen in the adult. Future work should aim to define when the adult PI‐LL relationship is realized.

AbstractBackgroundThyroid cancer is a growing threat to human health. Few studies have explored trends of thyroid cancer and relationships with social development factors. In this study, we explored the trend and relationship based on GBD.MethodsBy using GBD study, we obtained detailed data of thyroid cancer. Incidence, mortality and DALY were used to assess epidemiological characteristics. ASR and EAPC were used to estimate the trend.ResultsGlobally, the incidence significantly increased from 1990 to 2017, especially in high‐income regions. Males and middle SDI region demonstrated a higher increase of age‐standardized incidence rates. Unlike incidence trend, mortality trend showed a minor increase, and even showed a decreasing trend in some regions such as Eastern Sub‐Saharan Africa. Additionally, the DALY trend also demonstrated a slightly increase with an EAPC of 0.77 (95% CI 0.73–0.81). More significant increase of DALY was found in males, middle SDI region and high‐income Asia Pacific. The incidence of thyroid cancer peaked in middle‐aged people, while the mortality and DALY peaked in elder‐aged. Moreover, the proportion of thyroid cancer deaths contributable to high BMI was highest in developed countries and middle‐aged people.ConclusionsThyroid cancer is a public health problem worldwide. Over‐diagnosis might be partly responsible for its rising trend. It remains us to revise the guidelines to avoid unnecessary burdens. Moreover, we should pay attention to the risk factors of thyroid cancer. More targeted measures should be formulated to improve potential environmental and lifestyle‐related factors which might contribute to rising trend of thyroid cancer.
Lesbian mothers' perceptions and experiences of their school involvement
Authors: Iraklis Grigoropoulos 
Published: May 2021

AbstractLesbian‐parented families challenge the heteronormative dominant discourse of family in major social institutions such as schools. This study explores Greek lesbian mothers' experiences and perceptions of their interaction with the school personnel and other parents. Interpretative phenomenological analysis was used to analyse the data obtained through in‐person interviews with 14 lesbian mothers. The study revealed three overarching themes: (a) anticipating teachers' rejection, (b) non‐traditional family models are not addressed in school curricula, and (c) Managing disclosure. Participants' experiences of anticipated rejection, of hiding and concealing their family structure and sexual identity confirm that LGBTQ+ individuals live in a macro‐ and micro‐environmental context which adds to minority stress and produces essential new challenges. The findings of this study are discussed in the light of the institutional sources of minority stress that affect lesbian mothers.

Published: May 2021

AbstractA variety of π‐electronic ion‐pairing assemblies can be constructed by combining anion complexes of π‐electronic systems and countercations. In this study, a series of anion‐responsive π‐electronic molecules, dipyrrolyldiketone PtII complexes containing a phenylpyridine ligand, were synthesized. The resulting PtII complexes exhibited phosphorescence emission, with higher emission quantum yields (0.30–0.42) and microsecond‐order lifetimes, and solution‐state anion binding, as revealed by our spectroscopic analyses. These PtII complexes displayed solid‐state ion‐pairing assemblies, exhibiting various anion‐binding modes, which derived from pyrrole‐inverted and pyrrole‐non‐inverted conformations, and packing structures, with the contribution of charge‐by‐charge assemblies, which were dependent on the substituents in the PtII complexes and the geometries and electronic states of their countercations.

Published: May 2021

AbstractFullerene host‐guest constructs have attracted increasing attention owing to their molecular‐level hybrid arrangements. However, the usage of simple carbazolic derivatives to bind with fullerenes is rare. In this research, three novel carbazolic derivatives, containing a tunable bridging linker and carbazole units for the capturing of fullerenes, are rationally designed. Unlike the general concave‐convex interactions, fullerenes could interact with the planar carbazole subunits to form 2‐dimensional hexagonal/quadrilateral cocrystals with alternating stacking patterns of 1 : 1 or 1 : 2 stoichiometry, as well as the controllable fullerene packing modes. At the meanwhile, good electron‐transporting performances and significant photovoltaic effects were realized when a continuous C60⋅⋅⋅C60 interaction channel existed. The results indicate that the introduction of such carbazolic system into fullerene receptor would provide new insights into novel fullerene host‐guest architectures for versatile applications.

Published: May 2021

AbstractFlexible operation of air separation units may lead to enhanced thermal stress on the main heat exchanger, typically an aluminum plate‐fin heat exchanger. Hence, a large, cryogenic test rig has been built to investigate fatigue effects of dynamic operation. Nitrogen streams at –175 °C and 50 °C are applied to induce a highly repetitive series of temperature changes in two plate‐fin heat exchangers, which are extensively equipped with measurement technology to collect 3D temperature and strain data and to detect the provoked fatigue damages. Results of the measurements will be used to improve computational lifetime estimation tools.
A comparative analysis between late fusion of features approach and ensemble of multiple classifiers approach for image classification

Published: May 2021

SummaryIn recent times the late fusion of features approach for high‐level features extracted by multiple deep convolutional neural networks (DCNNs) has proven to be very effective in the computer vision field, especially for object classification problems. Pretrained DCNNs DenseNet‐121 and ResNet‐18 are retrained, keeping the number of output nodes equal to the number of classes present in the dataset. The last fully connected layers of these networks thereby get adapted to transform the high‐level features to a low‐dimensional feature map. Then these maps are fused to improve the performance of the model. On the other hand, an ensemble of multiple classifiers reduces the overfitting problem by combining multiple models prediction matrices. In this work, the prediction matrices of two Logsoftmax multiclass classifiers are combined. The feature maps for these two classifiers are extracted using pretrained DenseNet and ResNet. This study compares the late fusion of high‐level features approach and ensemble of multiple classifiers approach for object classification problems. Experimentation has been carried out on two benchmark datasets, such as CIFAR‐10 and CIFAR‐100, and it achieves 96.48% and 83.33% of test accuracy for ensemble of multiple classifiers and the late feature fusion approach. The proposed method has been compared with other deep architectures and datasets.
