Development of discussions on national housing statistics surveys in Japan
Authors: Horiuchi Keisuke , Nakae Ken 
Published: November 2021

AbstractIn this paper, the survey conducted by the government aimed at collecting fundamental statistics on housing is referred to as the “national housing statistics survey.” The purpose of this study is to clarify the background of the discussions on the national housing statistics survey in Japan and how these discussions were linked to the actual survey. Previous studies have recognized two surveys in 1941, the “Housing Survey of Industrial Cities” and the “Housing Survey of Larger Cities” as the first national housing statistical surveys in Japan, and revealed the background to how both surveys were conducted. In contrast, this paper also focused on the discussions that ensued between the 1920s and 1930s, and discovered that discussions on obtaining national housing statistics began in 1923, and Japanese researchers intended to include housing‐related items in the 1930 National Census. However, its implementation was incomplete owing to a lack of funds, and only the number of rooms was investigated. The results of the discussions up to 1930 were reflected in the discussions around 1940, and two surveys with many items were conducted to understand the actual detailed conditions of the houses existing in the “industrial cities” and “larger cities” where munitions industries were concentrated.

AbstractPurposeThe dual‐energy CT (DECT) LiverVNC application class in the Siemens Syngo.via software has been used to perform non‐iodine material decompositions. However, the LiverVNC application is designed with an optional size‐specific calibration based on iodine measurements. This work investigates the effects of this iodine‐based size‐specific calibration on non‐iodine material decomposition and benchmarks alternative methods for size‐specific calibrations.MethodsCalcium quantification was performed with split‐filter and sequential‐scanning DECT techniques on the Siemens SOMATOM Definition Edge CT scanner. Images were acquired of the Gammex MECT abdomen and head phantom containing calcium inserts with concentrations ranging from 50–300 mgCa/ml. Several workflows were explored investigating the effects of size‐specific dual‐energy ratios (DERs) and the beam hardening correction (BHC) function in the LiverVNC application. Effects of image noise were also investigated by varying CTDIvol and using iterative reconstruction (ADMIRE).ResultsWith the default BHC activated, Syngo.via underestimated the calcium concentrations in the abdomen for sequential‐scanning acquisitions, leaving residual calcium in the virtual non‐contrast images and underestimating calcium in the enhancement images for all DERs. Activation of the BHC with split‐filter images resulted in a calcium over‐ or underestimation depending on the DER. With the BHC inactivated, the use of a single DER led to an under‐ or overestimate of calcium concentration depending on phantom size and DECT modality. Optimal results were found with BHC inactivated using size‐specific DERs. CTDIvol levels and ADMIRE had no significant effect on results.ConclusionWhen performing non‐iodine material decomposition in the LiverVNC application class, it is important to understand the implications of the BHC function and to account for patient size appropriately. The BHC in the LiverVNC application is specific to iodine and leads to inaccurate quantification of other materials. The inaccuracies can be overcome by deactivating the BHC function and using size‐specific DERs, which provided the most accurate calcium quantification.
Robust fault‐tolerant attitude synchronization control for formation flying satellites

Published: November 2021

SummaryThis article investigates the fault‐tolerant attitude synchronization control problem for a team of formation flying satellites. The dynamics of each satellite is influenced by nonlinearities, parametric perturbations, external disturbances, and actuator faults. A robust fault‐tolerant formation flying controller is proposed, via the linear quadratic regulation method and the robust compensating theory, for the satellite team to achieve the desired attitude synchronization. Robustness analysis shows that the attitude tracking error of the global closed‐loop control system can converge into a given neighborhood of the origin in a finite time. Numerical simulation results validate the effectiveness and advantages of the proposed formation flying controller for the satellite team.

AbstractRhesus macaques are considered an important reservoir of different gastrointestinal (GI) zoonotic parasites affecting livestock and humans. Loads of GI parasites in the free‐ranging rhesus macaques living in close proximity to communities in Bangladesh are still unknown. To estimate the prevalence and diversity of zoonotic GI parasites in rhesus macaques of Bangladesh, a total of 182 freshly voided fecal samples were collected from macaques living in rural (N = 67), peri‐urban (N = 57), urban (N = 28), and Safari park (N = 30) between October 2015 and December 2016. All samples were tested by direct smear, sedimentation, flotation, and the McMaster techniques. A total of fourteen different taxa of GI parasites were detected, revealing an overall prevalence of 54.4% (n = 99; 95% confidence interval [CI]: 46.9–61.8). The prevalence of GI parasites was found to be significantly correlated with the mean parasitic taxa per individual in a group (r = 0.90;p = 0.002). The multivariable logistic regression analysis showed that the overall prevalence of GI parasites in macaques was significantly higher in those inhabiting rural areas (62.69%; odds ratio [OR]: 7.22;p = 0.001) and in macaques with interactions with other animals (60.98%; OR: 5.49;p = 0.005). Our results also indicated that the prevalence ofStrongyloidesspp. andBalantidium coliinfections varied significantly between land gradients. Our results also indicate that macaques frequently visit human settlements for food and are found interacting with domestic animals. In conclusion, the high prevalence of zoonotic GI parasite infection in rhesus macaques found in our study may pose a significant public health risk to communities, particularly in rural areas of Bangladesh. Health promotion to at‐risk communities focusing on limiting contact with rhesus macaques is necessary to mitigate potential zoonotic transmission.

Published: November 2021

AbstractThis paper describes structural elucidation of a layered conductive metal‐organic framework (MOF) material Cu3(C6O6)2 by microcrystal electron diffraction with sub‐angstrom precision. This insight enables the first identification of an unusual π‐stacking interaction in a layered MOF material characterized by an extremely short (2.73 Å) close packing of the ligand arising from pancake bonding and ordered water clusters within pores. Band structure analysis suggests semiconductive properties of the MOF, which are likely related to the localized nature of pancake bonds and the formation of a singlet dimer of the ligand. The spin of CuII within the Kagomé arrangement dominates the paramagnetism of the MOF, leading to strong geometrical magnetic frustration.

Published: November 2021

AbstractBroad functional group compatibility and gentle reaction conditions are the advantages of the majority of the palladium‐catalyzed reactions. Fascinating pharmacokinetic properties are possessed by the difluoromethyl group that is isopolar and isosteric to hydroxyl group. The difluoromethylene group is bioisostere for a carbonyl group or an oxygen atom. These groups are present in the structures of plenty of agrochemicals and drug molecules. Attempts to develop new approaches for difluoromethylation and difluoroalkylation reactions are growing notably. Owing to the importance of these compounds in diverse fields, the advances and prospects of palladium‐catalyzed difluoromethylation and difluoroalkylation reactions are reviewed here covering literature up to 2021.
The composition of edible oils modifies β‐sitosterol/γ‐oryzanol oleogels. Part II: Addition of selected minor oil components
Authors: Scharfe Maria , Prange Daniel , Flöter Eckhard 
Published: November 2021

AbstractThe role of selected minor oil components on sterol/sterol ester oleogels was studied. Therefore, oleic acid, tocopheryl acetate and monoglycerides were admixed with three vegetable oils, having different fatty acid compositions. Before that, minor natural components were removed from untreated oils (purification). Moreover, purified oils were subjected to a humidity treatment to increase their water content. All additives retarded the molecular self‐assembly of sitosterol with oryzanol, and the effect was dose‐dependent. Gel hardness only increased at low concentrations of tocopheryl acetate and decreased in all gels at higher concentrations. In contrast, was invariable in samples with oleic acid and monoglycerides and increased in gels containing tocopheryl acetate and water. Therefore, does not necessarily relate to the gels' compression firmness. Atomic force microscopy showed that the microstructure of oleogels was considerably modified by the additives. In general, a packed surface of twisted, thick bundles of tubules may be associated with a stiffer gel. Moreover, a composite structure in gels with monoglycerides was visible and confirmed by differential scanning calorimetry (DSC). DSC was used to determine gel–sol transition temperature and was associated with the number of tubules in the gel. The gel–sol temperature increased in samples 1.0% w/w oleic acid and tocopheryl acetate and decreased in gels with monoglycerides and water. The results show that oleogel properties can be significantly modified by minor components with functional groups. That was associated with interactions with the sterol and sterol ester in solution and with the surface of the tubules (ferulic acid moieties of oryzanol) in oleogels.

Published: November 2021

AbstractEveryone who drinks bottled water contributes at least 17 kg to the post‐consumer poly(ethylene terephthalate) (W‐PET) accelerating the accumulation of the waste plastics (WP) that already have an annual rate of increase of ~4.5%. Disposals of W‐PET mimics a pseudo‐renewable resource of WP, that creates many recycling and economic opportunities. This work presents a recycling method that reduces the burden of W‐PET on the environment while saves energy and creates new economic opportunities. The recovered purified PET (PET‐R) that its thermal properties are reported here was obtained by solvent extraction method. Five samples of PET‐R were analyzed by thermogravimetry to study its kinetics properties assuming that the degradation process followed a pseudo‐single component model. The isoconversional Ea,α values obtained from the f(α) functions were comparable to each other by the average and standard deviation of 200 ± 5 kJ mol−1; which is very close to the value of Ea of pure PET. The results were consistent with kinetics data reported in the literature for pure PET.
Effect of aspect ratio and bulk density of carbon nanotube on the electrical conductivity of polycarbonate/multi‐walled carbon nanotube nanocomposites

Published: November 2021

AbstractThis study investigated the electrical conductivity of PC/multi‐walled carbon nanotube (MWCNT) nanocomposites prepared by both compression and injection molding using three different MWCNTs. Among the three MWCNTs used, two of which have similarly low‐aspect ratio (AR) (60) but different bulk density (BD) (35 and 19 kg/m3). The third MWCNT has highest AR (150) and lowest BD (11 kg/m3) among the three MWCNTs. Our findings showed that CNTs having the lowest BD and the highest AR does not always produce the best dispersion quality and highest electrical conductivity, which is contradictory to existing studies. Among three MWCNTs, the MWCNT with lower AR (60) and a BD at the mid value (19 kg/m3) exhibited the highest electrical conductivity in injection‐molded samples. This MWCNT also exhibited the highest electrical conductivity in compression‐molded samples for MWCNT content above 2 wt%. This MWCNT provided better dispersion state than MWCNT with the highest AR (150) and lowest BD (11 kg/m3). We found that BD and AR have correlative effects in the individualization and dispersion of MWCNTs from its primary agglomerates. Lower BD can improve the ease of agglomerate disintegration during extrusion while a high‐AR beyond an optimal value can entangle and coil the MWCNTs, which can actually worsen the dispersion quality of the nanotubes.
Synthesis of graphene oxide functionalized by phytic acid for anticorrosive reinforcement of waterborne epoxy coating
Authors: Wang Lingyun , Chen Yaxin , Luo Jing , Liu Ren 
Published: November 2021

AbstractGraphene derivatives are excellent fillers for providing outstanding barrier performance in organic protective coating but no active inhibition property. In this paper, a facile and environmentally friendly strategy is presented to improve the anticorrosion ability of graphene by modifying graphene oxide (GO) with a green corrosion inhibitor derived from nature, phytic acid (PA). The as‐prepared PA modified GO (PAGO) thus possesses the passive barrier property and active corrosion inhibition function simultaneously. Employing PAGO as filler, a high‐performance waterborne epoxy composite coating (PAGO/WEP) with “barrier + inhibitor” double anticorrosion effect was fabricated. The EIS test results demonstrated that after 21 days of immersion, the impedance modulus of the PAGO/WEP coating did not decrease and still maintained at the initial impedance value. The salt spray tests also demonstrated the significantly enhanced anticorrosion performance.

AbstractObjectivesTo compare incidence of forearm radial artery occlusion (RAO) and hemostasis characteristics between distal and conventional transradial approach (DRA and TRA, respectively).BackgroundDRA has the potential advantage of reducing RAO. DRA effectively reduces time‐to‐hemostasis, however its role on preserving flow in the radial artery (PF) during hemostasis and consequent impact on RAO remains speculative.MethodsEight hundred thirty‐seven patients with TRA were previously enrolled in a prospective registry investigating the relationship of residual anticoagulation and RAO. Three hundred twenty‐six additional patients with DRA were added to the cohort and matched to the original cohort by propensity score. The composite end‐point of RAO at forearm and distal site of puncture (dRAO) was evaluated as secondary end‐point.ResultsRAO occurred in 4.8% (41 of 837) of patients undergoing TRA and in 0% (0 of 326) of those undergoing DRA (p < 0.0001). DRA was associated with higher percentage of PF (97.2% vs. 78.5% in TRA group, p < 0.0001) and reduced time‐to‐hemostasis (147 ± 99 min vs. 285 ± 138 min, p < 0.0001). After matching, hemostasis characteristics were still significant different (PF 95.7% vs. 90.1%, p = 0.023, and 190 ± 92 vs. 323 ± 162 min, p < 0.0001) with reduction in the incidence of RAO (0 of 213, 0% vs. 7 of 213, 3.3%, p = 0.0015). dRAO occurred in one case (0.3% and 0.5% after matching, p < 0.0001 and p = 0.032 compared to TRA).ConclusionsDRA was associated with lower rates of RAO compared to TRA. This effect is potentially explained by reduced time‐to‐hemostasis and maintained flow at the wrist during hemostasis.

AbstractAlthough single‐atom catalysts (SACs) show significantly higher catalytic performance compared to conventional and nanoparticle‐based catalysts (NPs) at the same amount of metal loading, their overall catalytic performance may still be unable to compete with the NPs in many applications due to the limited active sites. Generally, trace amounts of metal (less than 1 wt%) can be successfully loaded onto supports in an atomically‐dispersed feature, and higher metal loading usually results in aggregation of the metal atoms. Hence, it is very important to further increase the density of isolated metal atoms in these rising‐star SACs to pave the ways for widespread applications or even to replace the NPs. On the other hand, it is well known that this is one of the most challenging topics on SACs research. In this review, the advanced strategies to overcome this challenge and achieve high loading of isolated metal atoms on various supports will be extensively discussed together with the examples showing the research efforts to enrich the metal active sites from the pioneer works with metal loading below 0.2 wt% to the recently‐reported SACs with metal loading over 20 wt%. Besides, there are still plenty of rooms to further improve the quantity and quality of metal loading on different supports, and outlooks of this scope is provided. We hope that this comprehensive review aids in the development of synthesis techniques for the new‐generation SACs with richer active sites.

AbstractA single‐dose, open‐label, randomized‐sequence, 2×2 crossover study was conducted in healthy Chinese adults, after fasting and postprandial, to evaluate the bioequivalence of 2 pyrazinamide (PZA) formulations. Fasting and postprandial tests were conducted in 24 cases. Test‐reference and reference‐test were randomly divided into 2 sequence groups, with 12 cases in each group. The concentration of PZA in plasma was determined after 0.5 g single oral PZA test and reference formulations by the high‐performance liquid chromatography–tandem mass spectrometry method. In the fasting group, the 90% confidence intervals (CIs) of the 2 formulations maximum plasma concentration (Cmax), area under the plasma concentration–time curve (AUC) from time 0 to last detectable plasma concentration, and AUC from time 0 to infinity after logarithmic conversion were 104.8% to 121.9%, 97.7% to 101.6%, and 97.7% to 101.6%, respectively. In the postprandial group, the 90%CIs of the 2 formulations’ Cmax, AUC from time 0 to last detectable plasma concentration, and AUC from time 0 to infinity after logarithmic conversion were 86.4% to 100.2%, 96% to 102%, 95.8% to 102.3%, respectively. The 90%CIs of the test/reference Cmax ratio and AUC ratio were within the acceptable range of 80.00% to 125.00% for bioequivalence under both fasting and postprandial conditions. No serious adverse events occurred during treatment with the test formulation or the reference formulation.
Deprivation of direct adult contact during development affects social representation in a songbird
Authors: Perret Audrey , George Isabelle , Coulon Marion , Cousillas Hugo , Hausberger Martine , Henry Laurence 
Published: November 2021

AbstractSocial cognition involves a wide array of skills that are built largely through interactions with conspecifics and therefore depend upon early social experience. Motivation for social stimuli is a key feature of social behavior and an operant conditioning task showed that isolated wild‐caught adult starlings (Sturnus vulgaris) are highly motivated to access pictures of other starlings. Here, we show that hand‐raised adult starlings maintained in groups of peers throughout development but without any contact with adult models were not or only poorly motivated to access pictures of conspecifics. Moreover, they did not prefer pictures of starlings to pictures of landscapes, unlike birds wild‐caught as adults. These results raise questions about the role of social experience during development, particularly with adult models, in the development of social motivation and of social representation in general.
