Seismic auxetic metamaterials as novel earthquake protections

We propose that wave propagation through a class of elastodynamic metamaterials opens unprecedented avenues in seismic wave protection based on spectral properties of auxetic metamaterials. The elastic parameters of these metamaterials, like the Poisson ratio {\nu}, bulk modulus B, shear modulus G, or the mass density \r{ho}0, are known to exhibit negative values in elastic stop bands. We show here that the propagation of seismic waves with different frequencies can be influenced by a meter scale version of auxetic metamaterials buried in the soil. More precisely, we numerically examine and illustrate the markedly different behaviors between the propagation of seismic waves through a continuum isotropic elastic medium (concrete) and our seismic auxetic metamaterials utilized here like a foundation of the building one would like to protect. This novel class of seismic metamaterials opens band gaps at frequencies compatible with seismic waves when they are designed appropriately, what makes them interesting candidates for seismic isolation structures.
Tense as a Grammatical Category in Sinitic: A Critical Overview

Sinitic languages are very often described as tenseless, since they are generally seen as lacking ‘true’ grammatical markers of tense: thus, the interpretation of time reference relies on other factors, such as aspect, modal verbs, and the use of time expressions. However, the debate concerning the tenseless nature of Chinese has not been settled yet: several types of items in Sinitic have been analyzed as expressing both aspect and tense, tense and modality, or even tense only. In this paper, we offer a critical analysis of the proposals made in the description of Standard Mandarin Chinese and (so-called) Chinese dialects concerning grammatical exponents of tense. We shall show that there appears to be a very broad degree of variation within Sinitic in the type and nature of tense(-like) meanings expressed, with different degrees of overlap between tense and other TAM categories (i.e., aspect and modality), and different degrees of grammaticalisation of alleged tense markers. Furthermore, the most grammaticalised tense markers are located in subregions within northern China: we shall thus discuss the relevance of our data for the areal typology of Sinitic.
Late stent thrombosis as a complication of T and small protrusion bifurcation stenting: a case report

Abstract Background A case of stent thrombosis as a complication of coronary bifurcation stenting is described. We review potential complications of bifurcation stenting and established guidelines. Case summary A 64-year-old man presented with a non-ST segment elevation myocardial infarction. High-sensitivity troponin I peaked at 99 000 ng/L (normal <5). He previously had coronary stenting for stable angina when residing in another country 2 years previously. Coronary angiography revealed no significant stenosis with TIMI 3 flow in all vessels. Cardiac magnetic resonance imaging demonstrated a left anterior descending artery (LAD) territory regional motion abnormality, late gadolinium enhancement consistent with recent infarction, and a left ventricular apical thrombus. Repeat angiography and intravascular ultrasound (IVUS) confirmed bifurcation stenting at the junction of the LAD and second diagonal (D2) with protrusion of several millimetres of the uncrushed proximal segment of the D2 stent in the LAD vessel lumen. There was under-expansion of the LAD stent in the mid-vessel and stent malapposition in the proximal LAD, extending into the distal left main stem coronary artery and involving the ostium of the left circumflex coronary artery. Percutaneous balloon angioplasty was performed along the length of the stent, including an internal crush of the D2 stent. Coronary angiography confirmed a uniform expansion of the stented segments and TIMI 3 flow. Final IVUS confirmed full stent expansion and apposition. Discussion This case highlights the importance of provisional stenting as a default strategy and familiarity with procedural steps in bifurcation stenting. Furthermore, it emphasizes the benefit of intravascular imaging for lesion characterization and stent optimization.
Agglomerate Size Evolution in Solid Propellant Combustion under High Pressure

Solid propellant combustion and flow are significantly affected by condensed combustion products (CCPs) in solid rocket motors. A new aluminum agglomeration model is established using the discrete element method, considering the burning rate and formulation of the propellant. Combining the aluminum combustion and alumina deposition model, an analytical model of the evolution of CCPs is proposed, capable of predicting the particle-size distribution of completely burned CCPs. The CCPs near and away from the propellant burning surface are collected by a special quench vessel under 6~10 MPa, to verify the applicability of the CCP evolution model. Experimental results show that the predicted error of the proposed CCP evolution model is less than 8.5%. Results are expected to help develop better analytical tools for the combustion of solid propellants and solid rocket motors.

Existence of strong solutions for a system of interaction between a compressible viscous fluid and a wave equation

In this article, we consider a fluid–structure interaction system where the fluid is viscous and compressible and where the structure is a part of the boundary of the fluid domain and is deformable. The fluid is governed by the barotropic compressible Navier–Stokes system, whereas the structure displacement is described by a wave equation. We show that the corresponding coupled system admits a unique, strong solution for an initial fluid density and an initial fluid velocity in H 3 and for an initial deformation and an initial deformation velocity in H 4 and H 3 respectively. The reference configuration for the fluid domain is a rectangular cuboid with the elastic structure being the top face. We use a modified Lagrangian change of variables to transform the moving fluid domain into the rectangular cuboid and then analyze the corresponding linear system coupling a transport equation (for the density), a heat-type equation, and a wave equation. The corresponding results for this linear system and estimations of the coefficients coming from the change of variables allow us to perform a fixed point argument and to prove the existence and uniqueness of strong solutions for the nonlinear system, locally in time.
The Effect of Natrium Hydroxide Molarity Variation and Alkali Ratio on the Compressive Strength of Geopolymer Paste and Mortar

Geopolymers have great potential to replace conventional cementitious materials and are classified as green materials. Their main constituents are silica (Si) and aluminum (Al), which can be found in the fly ash material from industrial processes of the PLTU. The parameters that affect the strength of the concrete are influenced by the molarity of natrium hydroxide and the ratio of alkalis (NaOH/Na2SiO3). This study examined the characteristics of the geopolymer paste and mortar specimens. Furthermore, mixture composition was carried out using the weight ratio method. The mortar produced consists of 65% fine aggregate and 35% paste, while the pasta contains 60% fly ash and 40% alkaline solution. The molarities of NaOH used were 8M, 10M, 12M, and 14M with a base ratio of 1.5, 2, and 2.5 Na2SiO3/NaOH. The curing of specimens was carried out with the humid temperature method. The results showed that the highest compressive strength of geopolymer paste and mortar was obtained at 12M NaOH molarity with an alkaline ratio of 2.5, namely 12.59 MPa and 21.75 MPa at 28 days, respectively. NaOH of more than 12M can cause a decrease, while the base ratio of 2.5 has the highest strength. The results also showed that the higher the molarity of NaOH and the greater the alkaline ratios, the longer the setting time.
Lattice gases, large deviations, and the incompressible Navier-Stokes equations

We study the incompressible limit for a class of stochastic particle systems on the cubic lattice Zd, d = 3. For initial distributions corresponding to arbitrary macroscopic L2 initial data, the distributions of the evolving empirical momentum densities are shown to have a weak limit supported entirely on global weak solutions of the incompressible Navier-Stokes equations. Furthermore, explicit exponential rates for the convergence (large deviations) are obtained. The probability to violate the divergence-free condition decays at rate at least exp{-E-d+l}, while the probability to violate the momentum conservation equation decays at rate exp{fE-d+2} with an explicit rate function given by an HI1 norm.
Viability of Napier Grass Ash as Partial Substitute of Cement in CHB

The effects on the physical and mechanical properties of Napier grass ash (NGA) as substitute for ordinary Portland cement (OPC) on concrete hollow block (CHB) were investigated. Mix ratio of 1:2:4 with water-cement ratio of 0.60, and 10%, 15%, and 20% NGA replacements were adapted. Experimental procedures and testing conformed to American Society of Testing and Materials (ASTM) standards. Slump values, in comparison to control, showed a decline of 16.67%, 25%, and 58.33% for 10%, 15%, and 20% NGA replacements, respectively, which correlates to water absorption result. The denser the CHB, the lower the moisture content. Compressive strength results revealed that all NGA substitutes performed better than the control sample. NGA-20% had the highest compressive strength of 4.2 MPa (individual unit) and 3.9 MPa (average of 3 units) after 28 days of curing. Overall, NGA replacement was not viable for load-bearing but ideal for nonload-bearing CHB using the mix design.
Convergence in Distribution of the One-Dimensional Kohonen Algorithms when the Stimuli are not Uniform

We show that the one-dimensional self-organizing Kohonen algorithm (with zero or two neighbours and constant step ε) is a Doeblin recurrent Markov chain provided that the stimuli distribution μ is lower bounded by the Lebesgue measure on some open set. Some properties of the invariant probability measure vε (support, absolute continuity, etc.) are established as well as its asymptotic behaviour as ε ↓ 0 and its robustness with respect to μ.
Warm Jupiters Beyond the Tidal Synchronization Limit may Exhibit a Wide Range of Secondary Eclipse Depths

With the JWST we can now characterize the atmospheres of longer-orbit planets, but this moves us into a regime where we cannot assume that tidal forces from the star have eroded the planets’ obliquities and synchronized their rotation rates. These rotation vectors may be tracers of formation and evolution histories and also enable a range of atmospheric circulation states. Here we delineate the orbital space over which tidal synchronization and alignment assumptions may no longer apply and present three-dimensional atmospheric models of a hypothetical warm Jupiter over a range of rotation rates and obliquities. We simulate the secondary eclipses of this planet for different possible viewing orientations and times during its orbital, seasonal cycle. We find that the eclipse depth can be strongly influenced by the rotation rate and obliquity through the timing of the eclipse relative to the planet’s seasonal cycle, and advise caution in attempting to derive properties such as albedo or day–night transport from this measurement. We predict that if warm Jupiters beyond the tidal limit have intrinsic diversity in their rotation vectors, then this will manifest itself as dispersion in their secondary eclipse depths. We explore eclipse mapping as a way to uniquely constrain the rotation vector of warm Jupiters but find that the associated signals are likely at the edge of the JWST performance. Nevertheless, as the JWST begins to measure the secondary eclipses of longer-orbital-period planets, we should expect to observe the consequences of a wider range of rotation states and circulation patterns.
Study on the Influence of Salt Marsh Vegetation on Tidal Current and Sediment Transport in Intertidal Zone

Due to the sensitivity of the environment and immoderate human activities, the coastal zone in China is facing resource conflicts and environmental pressures. Salt marsh vegetation is regarded as an important measure for coastal ecological restoration. Therefore, it is of practical significance to study the influence of salt marsh vegetation on hydro-sediment dynamics. Based on the measured topography and tidal sediment data, a generalized model of salt marsh vegetation is established to study its effects on the dynamics of nearshore water and sediment. The results show that salt marsh vegetation has prominent effect of attenuating flow velocity and promoting sedimentation, and the ability differs depending on vegetation. Salt marsh vegetation can promote the development of tidal channels to shore, causing intensified erosion in the deep trough. The expansion of the vegetation area will allow the tidal channels to extend small branches to shore and connect with the vegetation front.
The absolute magnitudes of RR Lyrae stars – V. WY Antliae, W Crateris, RV Octantis and BB Puppis

We present infrared (JHK) light curves and radial velocity curves for four southern hemisphere RRab Lyraes (WY Ant, W Crt, RV Oct and BB Pup) and an infrared light curve for one RRc Lyrae (AU Vir). Absolute magnitudes are determined for the RRab stars, using a combination of the infrared flux method and the Baade-Wesselink method. Including these four stars, there are now 29 RR Lyraes that have been analysed, using these, or similar, methods. The best-fitting lines to these stars are = 0.21 (± 0.05)[Fe/H] + 1.04(± 0.10) and = −2.95(± 0.10) log P − 1.07 (± 0.10), where the quoted errors are, we believe, realistic rather than formal or internal
Risk perception of non-communicable diseases: A systematic review on its assessment and associated factors

Background The burden of non-communicable diseases (NCDs) is increasing. Risk perception of NCDs is an important factor towards the uptake of preventive health interventions. There are various questionnaires assessing risk perception of NCDs, but no internationally standardized questionnaire has been available. Identification of factors associated with risk perception of NCDs may facilitate the development of targeted interventions. This systematic review aims to identify available questionnaire assessing risk perception of NCDs and the factors associated with risk perception of NCDs. Methods The reporting of this systematic review is in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We carried out a literature search through three databases (Scopus, PubMed, Web of Science) and targeted original article published in English between 2012 and 2021. Quality appraisal of the eligible articles was conducted using the Mixed Methods Appraisal Tool. Findings were synthesized using content analysis. Results A total of 86 studies were included. We found a variety of questionnaires assessing risk perception of NCDs, with many differences in their development, domains, items and validity. We also identified several personal, sociopsychological and structural factors associated with risk perception of NCDs. Limitations Most of the included studies were of cross-sectional design, and therefore the quality of evidence was considered low and exhibit a high risk of bias. The role of publication bias within this systematic review should be acknowledged as we did not include grey literature. Additionally, language bias must be considered as we only included English-language publications. Conclusion Further development and testing of available questionnaire is warranted to ensure their robustness and validity in measuring risk perception of NCDs. All the identified factors deserve further exploration in longitudinal and experimental studies.
Dirac distribution and Dirac constraint quantizations

We explore two ways of quantizing constraints through integral quantizations based on the Weyl–Heisenberg group. The first one is based on the quantization of distributions on phase space expressing geometric constraints, like Dirac or Heaviside distributions. The second one is implemented in the spirit of Dirac. In both cases we complete the study with a semiclassical analysis through the use of lower symbols. For the sake of simplicity, we restrict our study to the complex plane viewed as the phase space of the motion on the line, or as the phase space for classical electromagnetic radiation (quadratures). Despite the fact that the two procedures do not in general yield identical results, we show interesting features in exploring aspects of their quantum and semiclassical versions.
Validation of a genome-wide polygenic score in improving fracture risk assessment beyond the FRAX tool in the Women’s Health Initiative study

Background Previous study has established two polygenic scores (PGSs) related to femoral neck bone mineral density (BMD) (PGS_FNBMDldpred) and total body BMD (PGS_TBBMDldpred) that are associated with fracture risk. However, these findings have not yet been externally validated in an independent cohort. Objectives This study aimed to validate the predictive performance of the two established PGSs and to investigate whether adding PGSs to the Fracture Risk Assessment Tool (FRAX) improves the predictive ability of FRAX in identifying women at high risk of major osteoporotic fracture (MOF) and hip fractures (HF). Methods The study used the Women’s Health Initiative (WHI) cohort of 9,000 postmenopausal women of European ancestry. Cox Proportional Hazard Models were used to assess the association between each PGS and MOF/HF risk. Four models were formulated to investigate the effect of adding PGSs to the FRAX risk factors: (1) Base model: FRAX risk factors; (2) Base model + PGS_FNBMDldpred; (3) Base model + PGS_TBBMDldpred; (4) Base model + metaPGS. The reclassification ability of models with PGS was further assessed using the Net Reclassification Improvement (NRI) and the Integrated discrimination improvement (IDI). Results The study found that the PGSs were not significantly associated with MOF or HF after adjusting for FRAX risk factors. The FRAX base model showed moderate discrimination of MOF and HF, with a C-index of 0.623 (95% CI, 0.609 to 0.641) and 0.702 (95% CI, 0.609 to 0.718), respectively. Adding PGSs to the base FRAX model did not improve the ability to discriminate MOF or HF. Reclassification analysis showed that compared to the model without PGS, the model with PGS_TBBMDldpred (1.2%, p = 0.04) and metaPGS (1.7%, p = 0.05) improve the reclassification of HF, but not MOF. Conclusions The findings suggested that incorporating genetic information into the FRAX tool has minimal improvement in predicting HF risk for elderly Caucasian women. These results highlight the need for further research to identify other factors that may contribute to fracture risk in elderly Caucasian women.
The impact of a rosemary containing drink on event-related potential neural markers of sustained attention

Background Research suggests that the ingestion or aroma of rosemary enhances cognitive ability in both rodents and humans. However, how rosemary facilitates cognition and the precise therapeutic impacts on information processing remains unclear. Hypothesis/purpose This pilot study used the temporal precision of event-related potentials (ERPs) to examine the cognitive-enhancing benefits of a rosemary drink. Neural markers of sustained attention were used as indices to explore whether rosemary facilitates concentration in general or the allocation of resources to task-relevant information only. Study design and methods In a between-subject design (rosemary vs water control drink), 48 adults performed a 3-stimulus visual oddball task. Participants differentiated between rare target stimuli (index of task-relevant attentional processes; P3b ERP) embedded in a train of frequent stimuli. The presentation of an infrequent novel stimulus was also included (index of task-irrelevant stimulus processing; P3a ERP). Throughout the session, electroencephalograms (EEG) were collected and time-locked to the presentation of the target (P3b) and novel (P3a) stimulus types. Results The primary analyses revealed facilitation of the P3a in particular with a medium Cohen’s effect size reported. The investigation of the P3b component, although less reliable, also had a medium effect. The subsidiary consideration of the association between behaviour and the ERPs provided a further level of explanation regarding the therapeutic effect of rosemary on cognition. Indeed, the pattern of associations was suggestive of strategy differences during the performance of the task across the treatment group. , although these data should be treated with caution. Conclusions These pilot data provide critical insights into the utility of rosemary to facilitate different aspects of attention. In particular, data are consistent with rosemary providing additional attentional resources to enhance the processing of stimuli we encounter, irrespective of task relevance. Indeed, the enhancement of both P3a and P3b components following rosemary administration may indicate that the herb enhances the processing of all stimuli in the environment. We argue for the use of both behavioural and EEG methods to explore the therapeutic effects of herbal compounds.
Factors affecting unmet healthcare needs in female baby boomers: Andersen model application in Korea

This study aimed to measure unmet healthcare needs and investigate the factors affecting them in female baby boomers (individuals born between 1955 and 1963) using the Korea Health Panel Data 2017 from February to June 2017 by the Korea Institute for Health and Social Affairs and the National Health Insurance Corporation. The data were analyzed using descriptive statistics, chi-square test, t-test, and multiple logistic regression using SPSS WIN 25.0 program. The results showed that the proportion of unmet healthcare needs was 11.1%, and the primary reason for unmet healthcare needs was the lack of visitation time. Female baby boomers experienced more unmet healthcare needs when they had no spouse (1.63 times), eating problems (2.33 times), and stress (1.31 times). This study is significant because it measured the unmet healthcare needs of women in the baby boomer generation and identified the factors influencing unmet healthcare needs. The study’s results can help provide essential data to decrease the unmet healthcare needs of female baby boomers.
