Abstract
At present, the history of Chinese ancient architecture has a long history and independent development. As early as The Shang Dynasty, Chinese architectural system has been initially formed. Until the beginning of the 20th century, it has always maintained its own structure and layout principles, and has been widely spread to other countries. BIM Technology is a rapidly rising digital modeling technology in recent years, which is widely used in the construction industry. Its intuition and accuracy have become the advantages of its rapid development. At the same time, BIM Technology can also better protect ancient buildings from the perspective of information. Starting from the ancient building restoration industry, this paper analyzes the current development trend of the domestic ancient building industry, and summarizes the key problems existing in the existing ancient building restoration methods. This paper analyzes and discusses the advantages and functions of BIM technology. According to the example of the old office building of Fengtian Zhaoxin Kiln Company, a BIM model is established. Starting from the application of BIM technology in survey and design, construction process management and repair of special parts, the actual application of BIM technology in ancient building repair is discussed, and valuable results are obtained.

Published: June 2021

Abstract
In recent years, with the continuous development of economy, people’s living standards have been continuously improved, urbanization has become more and more perfect, and requirements for indoor environmental art design have become higher and higher. The requirements for interior decoration have changed from the original decoration materials to be strong and durable to the modern decoration which is mainly beautiful and comfortable. Soft decoration materials play a vital role, because indoor soft decoration materials are the most important factor in determining the interior decoration style factor. In the decoration market at this stage, there is a saying that light decoration is heavy decoration, which shows the importance of soft decoration in indoor environmental art.

Authors: Li Bing , Yang Xiaofan 
Published: June 2021

Abstract
With the continuous development of the society, the business environment has changed, and consumers’ consumption concepts have been updated, and consumers are in pursuit of efficient and diversified commercial space experience. Traditional commercial buildings are difficult to meet the new needs of people, and new materials and new technologies emerge in an endless stream to meet the needs of architectural development. This puts forward higher requirements to the design of commercial buildings. At present, new space in commercial buildings has emerged, and more architectural technologies have been applied in commercial buildings. Commercial space is constantly changing and reconstructing with the development of The Times and the needs of consumers.

Authors: Tan Songlin , Zhuang Yongqi , Yi Jianhong 
Published: June 2021

Abstract
The multi-wall carbon nanotube (MWCNT) reinforced alumina (Al2O3) matrix composites were fabricated by spray drying and vacuum hot-pressing sintering. The mechanical properties of the composites with different mass fractions of MWCNT were studied. The flexural strength and fracture toughness of the composite were 498.3 MPa and 5.69 MPa·m 1/2, respectively, which were about 55.3% and 84.7% higher than that of pure Al2O3. With the increase in the content of MWCNT, the Vickers hardness and relative density of the composite decreased gradually. The correlation between the microstructure and the mechanical properties of the composite was analyzed.
The formation of sigma phase in the CoCrFeNi high-entropy alloys
Authors: Wang X J , Xu M , Liu N , Liu L X 
Published: June 2021

Abstract
The as-cast CoCrFeNi high-entropy alloys show simple FCC structure and outstanding deformation ability at room temperature. Respectively, after 50% of deforming at room temperature and annealing at intermediate temperature range of 600 °C–800 °C for 2 h, CoCrFeNi alloys still show simple-phase FCC structure. It is noteworthy that CoCrFeNi high-entropy alloys can’t be strengthened by means of annealing, while deformation is an effective way to strengthen the alloys. It is investigated that the formation of sigma (σ) phase in high-entropy alloys is closely related to the difference of atomic radius (δ), the concentration of valence electron (VEC) and paired sigma-forming element (PSFE) content, and PSFE plays an crucial role. When PSFE > 40 at.%, 6.75 ≤ VEC ≤ 7.86, 4.0 ≤ δ ≤ 7.2, σ phase is prone to form in high-entropy alloys. In addition, alloying and processing route are two important factors that affect the sigma-formation in CoCrFeNi high-entropy alloys.

Abstract
A central challenge for systems neuroscience and artificial intelligence is to understand how cognitive behaviors arise from large, highly interconnected networks of neurons. Digital simulation is linking cognitive behavior to neural activity to bridge this gap in our understanding at great expense in time and electricity. A hybrid analog–digital approach, whereby slow analog circuits, operating in parallel, emulate graded integration of synaptic currents by dendrites while a fast digital bus, operating serially, emulates all-or-none transmission of action potentials by axons, may improve simulation efficacy. Due to the latter’s serial operation, this approach has not scaled beyond millions of synaptic connections (per bus). This limit was broken by following design principles the neocortex uses to minimize its wiring. The resulting hybrid analog–digital platform, Neurogrid, scales to billions of synaptic connections, between up to a million neurons, and simulates cortical models in real-time using a few watts of electricity. Here, we demonstrate that Neurogrid simulates cortical models spanning five levels of experimental investigation: biophysical, dendritic, neuronal, columnar, and area. Bridging these five levels with Neurogrid revealed a novel way active dendrites could mediate top-down attention.
From smart city to digital urban commons: Institutional considerations for governing shared mobility data
Authors: Creutzig Felix 
Published: June 2021

Abstract
Smart and shared mobility, from e-scooters to pool-riding services, reshape mobility in cities worldwide. While there is wide scope for new business opportunity in mobility, administrations remain unclear of how to manage and organize shared mobility and the big data underpinning shared mobility to serve the public good, in particular by reducing congestion and greenhouse gas emissions. Here, we suggest that management of smart mobility data constitutes a new layer of urban infrastructure that is integral to reaching sustainability goals. We investigate how integrated data management can realize the benefits of big data applications, while effectively managing risks, exemplifying our argument for the case of shared mobility in Israel. We argue that shared mobility and associated data management is neither necessary nor sufficient condition for sustainable mobility. However, given the current trend towards digitalization, data rentiership and surveillance capitalism, we suggest that institutionalizing data management of smart and shared mobility as a public good is a wise move that protects mobility users and facilitates efforts to steer shared mobility systems to low-carbon, low-congestion, and inclusive mobility. We develop a typology of six data platforms and find that integrated data platforms offer an opportunity to leverage benefits if three key design principles are followed: (1) open (but not necessarily free) data access; (2) maintaining the privacy, agency and participation of individuals, users, and the public; and (3) tailoring mobility services to meet well-defined goals of public policy.

Abstract
As source of sensory information, the body provides a sense of agency and self/non-self-discrimination. The integration of bodily states and sensory inputs with prior beliefs has been linked to the generation of bodily self-consciousness. The ability to detect surprising tactile stimuli is essential for the survival of an organism and for the formation of mental body representations. Despite the relevance for a variety of psychiatric disorders characterized by altered body and self-perception, the neurobiology of these processes is poorly understood. We therefore investigated the effect of psilocybin (Psi), known to induce alterations in self-experience, on tactile mismatch responses by combining pharmacological manipulations with simultaneous electroencephalography–functional magnetic resonance imaging (EEG–fMRI) recording. Psi reduced activity in response to tactile surprising stimuli in frontal regions, the visual cortex, and the cerebellum. Furthermore, Psi reduced tactile mismatch negativity EEG responses at frontal electrodes, associated with alterations of body- and self-experience. This study provides first evidence that Psi alters the integration of tactile sensory inputs through aberrant prediction error processing and highlights the importance of the 5-HT2A system in tactile deviancy processing as well as in the integration of bodily and self-related stimuli. These findings may have important implications for the treatment of psychiatric disorders characterized by aberrant bodily self-awareness.

Abstract
Folic acid (FA) has been reported to inhibit astrocyte apoptosis and improve aging-induced disorders; however, its role in telomere attrition remains unclear. In present study, 4-month-old senescence-accelerated mouse prone 8 (SAMP8) mice were assigned to four treatment groups for the in vivo experiment: FA-deficient diet (FA-D) group, FA-normal diet (FA-N) group, low FA-supplemented diet (FA-L) group, and high FA-supplemented diet (FA-H) group. These mice were euthanized when 10 months old. There was also a young SAMP8 (4 months old) control group (Con-Y) fed with FA-normal diet. In in vitro study, primary cultures of astrocytes from hippocampus and cerebral cortex were incubated for five generations with various concentrations of FA (0–40 μM) and were assigned to five groups: FA 0 μM (generation 5), FA 10 μM (generation 5), FA 20 μM (generation 5), FA 40 μM (generation 5), and FA 10 μM (generation 1). The results showed that FA supplementation inhibited aging-induced astrocytosis, astrocyte apoptosis, neurodegeneration, and prevented telomere attrition in hippocampus and cortex of SAMP8 mice. FA supplementation also decreased apoptosis and telomere attrition, and increased telomerase activity, in primary cultures of astrocytes. These results showed that it may be one of the mechanisms that FA inhibiting aging-induced apoptosis of astrocyte by alleviating telomere attrition.

Little is known about severe acute respiratory syndrome coronavirus 2 “vaccine-breakthrough” infections (VBIs). Here we characterize 24 VBIs in predominantly young healthy persons. While none required hospitalization, a proportion endorsed severe symptoms and shed live virus as high as 4.13 × 103 plaque-forming units/mL. Infecting genotypes included both variant-of-concern (VOC) and non-VOC strains.
Dehydration risk is associated with reduced nest attendance and hatching success in a cooperatively breeding bird, the southern pied babbler Turdoides bicolor

Published: June 2021

Abstract
High air temperatures have measurable negative impacts on reproduction in wild animal populations, including during incubation in birds. Understanding the mechanisms driving these impacts requires comprehensive knowledge of animal physiology and behaviour under natural conditions. We used a novel combination of a non-invasive doubly labelled water (DLW) technique, nest temperature data and field-based behaviour observations to test effects of temperature, rainfall and group size on physiology and behaviour during incubation in southern pied babblers Turdoides bicolor, a cooperatively breeding passerine endemic to the arid savanna regions of southern Africa. The proportion of time that clutches were incubated declined as air temperatures increased, a behavioural pattern traditionally interpreted as a benefit of ambient incubation. However, we show that (i) clutches had a &lt;50% chance of hatching when exposed to daily maximum air temperatures of &gt;35.3°C; (ii) pied babbler groups incubated their nests almost constantly (99% of daylight hours) except on hot days; (iii) operative temperatures in unattended nests frequently exceeded 40.5°C, above which bird embryos are at risk of death; (iv) pied babblers incubating for long periods of time failed to maintain water balance on hot days; and (v) pied babblers from incubating groups lost mass on hot days. These results suggest that pied babblers might leave their nests during hot periods to lower the risk of dehydration associated with prolonged incubation at high operative temperatures. As mean air temperatures increase and extreme heat events become more frequent under climate change, birds will likely incur ever greater thermoregulatory costs of incubation, leading to compromised nest attendance and increased potential for eggs to overheat, with implications for nest success and, ultimately, population persistence.

Abstract

Aims
Compared with adult patients, clinical manifestations of children’s coronavirus disease-2019 (COVID-19) are generally perceived as less severe. The objective of this study was to evaluate cardiac involvement in previously healthy children with asymptomatic or mildly symptomatic severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection.

Methods and results
We analysed a cohort of 53 paediatric patients (29 males, 55%), mean age 7.5 ± 4.7 years, who had a confirmed diagnosis of SARS-CoV-2 infection and were asymptomatic or only mildly symptomatic for COVID-19. Patients underwent standard transthoracic echocardiogram and speckle tracking echocardiographic study at least 3 months after diagnosis. Thirty-two age, sex, and body surface area comparable healthy subjects were used as control group. Left ventricular ejection fraction was within normal limits but significantly lower in the cases group compared to controls (62.4 ± 4.1% vs. 65.2 ± 5.5%; P = 0.012). Tricuspid annular plane systolic excursion (20.1 ± 3 mm vs. 19.8 ± 3.4 mm; P = 0.822) and left ventricular (LV) global longitudinal strain (−21.9 ± 2.4% vs. −22.6 ± 2.5%; P = 0.208) were comparable between the two groups. Regional LV strain analysis showed a significant reduction of the LV mid-wall segments strain among cases compared to controls. Furthermore, in the cases group, there were 14 subjects (26%) with a regional peak systolic strain below −16% (−2.5 Z score in our healthy cohort) in at least two segments. These subjects did not show any difference regarding symptoms or serological findings.

Conclusion
SARS-CoV-2 infection may affect left ventricular deformation in 26% of children despite an asymptomatic or only mildly symptomatic acute illness. A follow-up is needed to verify the reversibility of these alterations and their impact on long-term outcomes.

Published: June 2021

AbstractAims Despite the high use of cardioprotective medications, the risk factor control in patients with coronary heart disease (CHD) is still inadequate. Guidelines identify healthy lifestyles as equally important in secondary prevention as pharmacotherapy. Here, we describe reasons for poor lifestyle adherence from the patient’s perspective.Methods and results In the EUROASPIRE IV and V surveys, 16 259 CHD patients were examined and interviewed during a study visit ≥6 months after hospital discharge. Data gathering was fully standardized. The Brief Illness Perception questionnaire was completed by a subsample of 2379 patients. Half of those who were smoking prior to hospital admission, were still smoking; 37% of current smokers had not attempted to quit and 51% was not considering to do so. The prevalence of obesity was 38%. Half of obese patients tried to lose weight in the past month and 61% considered weight loss in the following month. In relation to physical activity, 40% was on target with half of patients trying to do more everyday activities. Less than half had the intention to engage in planned exercise. Only 29% of all patients was at goal for all three lifestyle factors. The number of adverse lifestyles was strongly related to the way patients perceive their illness as threatening. Lifestyle modifications were more successful in those having participated in a cardiac rehabilitation and prevention programme. Patients indicated lack of self-confidence as the main barrier to change their unhealthy behaviour.Conclusion Modern secondary prevention programmes should target behavioural change in all patients with adverse lifestyles.
The Dryas iulia Genome Supports Multiple Gains of a W Chromosome from a B Chromosome in Butterflies

Published: June 2021

Abstract
In butterflies and moths, which exhibit highly variable sex determination mechanisms, the homogametic Z chromosome is deeply conserved and is featured in many genome assemblies. The evolution and origin of the female W sex chromosome, however, remains mostly unknown. Previous studies have proposed that a ZZ/Z0 sex determination system is ancestral to Lepidoptera, and that W chromosomes may originate from sex-linked B chromosomes. Here, we sequence and assemble the female Dryas iulia genome into 32 highly contiguous ordered and oriented chromosomes, including the Z and W sex chromosomes. We then use sex-specific Hi-C, ATAC-seq, PRO-seq, and whole-genome DNA sequence data sets to test if features of the D. iulia W chromosome are consistent with a hypothesized B chromosome origin. We show that the putative W chromosome displays female-associated DNA sequence, gene expression, and chromatin accessibility to confirm the sex-linked function of the W sequence. In contrast with expectations from studies of homologous sex chromosomes, highly repetitive DNA content on the W chromosome, the sole presence of domesticated repetitive elements in functional DNA, and lack of sequence homology with the Z chromosome or autosomes is most consistent with a B chromosome origin for the W, although it remains challenging to rule out extensive sequence divergence. Synteny analysis of the D. iulia W chromosome with other female lepidopteran genome assemblies shows no homology between W chromosomes and suggests multiple, independent origins of the W chromosome from a B chromosome likely occurred in butterflies.
Exploring the Sustainability of Age-Friendly Initiatives in a Canadian Province

Published: June 2021

Abstract

Background and Objectives
Based on the World Health Organization Age-Friendly Cities and Communities (AFCC) framework, the government of Manitoba, Canada, launched a province-wide age-friendly initiative in 2008. The objective of this study was to explore the sustainability of the AFCC initiative more than a decade later. The study was guided by conceptualizations of sustainability as multidimensional and dynamic, composed of 4 aspects (continued capacity, institutionalization, continued benefits, and development/adaptation), and an ecologic perspective that highlights the importance of contextual influences, and their change over time, on AFCC activities.

Research Design and Methods
The study involved a qualitative, multiple case study design. Semistructured interviews were conducted in 2020 with a key informant from each of 52 AFCC. Interview data were analyzed deductively, guided by the sustainability framework and an ecologic perspective. Census data were used to describe the demographic characteristics of AFCC.

Results
We identified 6 groups of AFCC initiatives that varied in degree from the most to the least sustainable: active, in hiatus, reorganized, stalled, discontinued, and never got off the ground. Both local community factors (e.g., lack of capacity) and broader contextual factors, such as demographic changes and provincial legislations, influenced initiatives’ sustainability.

Discussion and Implications
AFCC initiatives can range in their degree of sustainability and can wax or wane over time. Ongoing external support for AFCC (e.g., from provincial or state government) to promote the vision of age-friendliness and to address lack of capacity (e.g., to assist with community assessments) could help with the long-term sustainability of initiatives.
