Abstract
In the article, the viability of adopting photovoltaic energy systems to convert solar energy into hydrogen in Iraqi four main cities are examined. A 22 kWp off-grid solar system, an 8 kW alkaline electrolyzer, a hydrogen compressor, and a hydrogen tank were modeled for an entire year in order to produce hydrogen. Using hourly experimental weather data from 2021 to 2030, MATLAB/Simulink is used to create a mathematical model of the recommended system behavior. The results revealed a range of annual hydrogen production from 1713.92 to 1891.12 kg, annual oxygen production from 1199.74 to 1323.78 kg, and annual water consumption from 7139.91 to 7877.29 L. Each kilogram of hydrogen costs $3.79. The results indicate that the optimal location for solar hydrogen production systems might be constructed in the central region of Iraq and in other regions with comparable climatic characteristics, particularly those with high radiation levels.
Down the paths to the past habitual: its historical connections with counterfactual pasts, future in the pasts, iteratives and lexical sources in Ancient Greek
Authors: la Roi Ezra 
Published: October 2022

Abstract
To complement existing synchronic typological studies of the marking strategies of (past) habituality, this paper details the diachronic paths leading to and from past habitual constructions. The rich corpus evidence from the diachrony of Ancient Greek demonstrates at least four source constructions: (1) past counterfactual mood (in optative and indicative), (2) futures in the past, (3) iteratives (with -sk) and (4) lexical sources with semantic affinity to habituality (volition, habit, love). It is argued that the former two acquire habitual meaning through an invited inference of epistemic certainty of the statement by the speaker: what certainly would have happened in the knowable past is implied to be characteristic of the past. The past forms with the so-called iterative -sk (3) suffix follow the cross-linguistically frequent evolution of pluractional constructions through a form of semantic bleaching: past iterative > frequentative > habitual > habitual imperfective. Lexical sources (4) first acquire habitual meaning in the present after which only the more heavily grammaticalized ones receive past habitual usage through semantic bleaching and generalization of usage (as reflected by host class expansions). The paper is concluded with a diachronic map of these paths into habituality and the paths leading from past habituality into other domains such as genericity.

Abstract
Accurate and regulated protein targeting is crucial for cellular function and proteostasis. In the yeast Saccharomyces cerevisiae, peroxisomal matrix proteins, which harboring a Peroxisomal Targeting Signal 1 (PTS1), can utilize two paralog targeting factors, Pex5 and Pex9, to target correctly. While both proteins are similar and recognize PTS1 signals, Pex9 targets only a subset of Pex5 cargo proteins. However, what defines this substrate selectivity remains uncovered. Here, we used unbiased screens alongside directed experiments to identify the properties underlying Pex9 targeting specificity. We find that the specificity of Pex9 is largely determined by the hydrophobic nature of the amino acid preceding the PTS1 tripeptide of its cargos. This is explained by structural modeling of the PTS1-binding cavities of the two factors showing differences in their surface hydrophobicity. Our work outlines the mechanism by which targeting specificity is achieved, enabling dynamic rewiring of the peroxisomal proteome in changing metabolic needs.
Detection of atypical response trajectories in biomedical longitudinal databases
Authors: Pantazis Lucio José , García Rafael Antonio 
Published: October 2022

AbstractMany health care professionals and institutions manage longitudinal databases, involving follow-ups for different patients over time. Longitudinal data frequently manifest additional complexities such as high variability, correlated measurements and missing data. Mixed effects models have been widely used to overcome these difficulties. This work proposes the use of linear mixed effects models as a tool that allows to search conceptually different types of anomalies in the data simultaneously.
A copula-based set-variant association test for bivariate continuous, binary or mixed phenotypes
Authors: St-Pierre Julien , Oualkacha Karim 
Published: October 2022

Abstract
In genome wide association studies (GWAS), researchers are often dealing with dichotomous and non-normally distributed traits, or a mixture of discrete-continuous traits. However, most of the current region-based methods rely on multivariate linear mixed models (mvLMMs) and assume a multivariate normal distribution for the phenotypes of interest. Hence, these methods are not applicable to disease or non-normally distributed traits. Therefore, there is a need to develop unified and flexible methods to study association between a set of (possibly rare) genetic variants and non-normal multivariate phenotypes. Copulas are multivariate distribution functions with uniform margins on the [0, 1] interval and they provide suitable models to deal with non-normality of errors in multivariate association studies. We propose a novel unified and flexible copula-based multivariate association test (CBMAT) for discovering association between a genetic region and a bivariate continuous, binary or mixed phenotype. We also derive a data-driven analytic p-value procedure of the proposed region-based score-type test. Through simulation studies, we demonstrate that CBMAT has well controlled type I error rates and higher power to detect associations compared with other existing methods, for discrete and non-normally distributed traits. At last, we apply CBMAT to detect the association between two genes located on chromosome 11 and several lipid levels measured on 1477 subjects from the ASLPAC study.

Abstract
By simulating the aroma changes during in vitro mastication, we can better understand the aroma changes during rice eating, which is helpful in studying people’s sensory preferences. To investigate the rice aroma released during the in vitro mastication, the present study analyzed rice bolus’s odor fingerprints in vitro mastication using electronic nose and gas chromatography-ion mobility spectrometry (GC-IMS). The electronic nose analysis results showed significant differences in the flavor of japonica rice in vitro mastication. In addition, GC-IMS determined 30 volatile organic compounds (VOCs) during rice in vitro mastication. Among these compounds, the most important content was aldehydes, followed by ketones and alcohols. Although the concentration of various chemicals was relatively high in cooked rice, most compounds decreased after mastication. The concentration of propan-2-ol, ethanol, and methanol increased after mastication. Multivariate data analysis showed that isoamyl sovalerate, pentanal, hexanal, acetone, hexanal, and limonene were the main VOCs of japonica rice during in vitro mastication. GC-IMS and e-nose analyses are complementary and recommended for using the two techniques to achieve the VOCs’ rapid and comprehensive detection during in vitro mastication. Results from this study allowed us to understand rice flavor during oral processing.

Abstract
Mandarin peel, an agro waste has an immense potential for bio utilization. The present study highlights the effect of drying on the physicochemical and biochemical properties of dried mandarin peel. Microwave drying and forced air drying accomplished at three different power levels (180, 360 and 540 W) and temperatures (30, 50 and 70 °C), respectively, while freeze drying was carried out at shelf temperature of –35 °C. The results revealed highest recovery of bioactive compounds from microwave drying at 540 W viz total phenolic (43.61 mg GAE/g), flavonoid (8.08 mg QE/g), tannin (8.73 mg GAE/g), saponin (159.91 mg EE/g−1), as well as, gallic acid antioxidant activity (3.58 mg GAEAC/g) and ferric reducing antioxidant power (50.61 mg TE/g−1). Furthermore, results from HPLC and UV–vis spectroscopy revealed presence of major polyphenols in dried peel. Microwave drying can be concluded as an industrial method for the bio utilization of mandarin peel.

Published: October 2022

Abstract
The actor Zheng Zhegu is a long-forgotten pioneer in Chinese film. He is perhaps best known for playing the part of Carpenter Zheng in China’s earliest surviving film, Labourer’s Love. Both professionals in the film industry and audiences of the time recognized him as achieving new heights in acting. Starting with Zheng Zhegu’s personal story, this article explores the history of performances in early Chinese film. It emphasizes the transition from “new play-oriented” screen acting to interiors performances, placing this shift in the transformation of Chinese cinema from a “cinema of attractions” to narrative films.
A critical discourse account of the process of ideological expressions in the Ẹdo (Bini) guilds
Authors: Aigbẹdo William Ighasere 
Published: October 2022

AbstractThe study examines how language, peculiar to members of the guilds in Ẹdo, is used to express their cultural ideology. This is expected to provide the necessary insight and comprehension of the nature of the guilds’ socio-cultural activities resulting in the distinct ideology expressed by them. Data were purposively collected through the indepth interview of key informants (individuals with knowledge of the activities of the guilds examined) and direct observation of the interaction between the members of the different guilds. The collected data were subjected to discursive analysis. The language used by the guilds in interaction among members is a marker of the guilds ideological orientation as this serves to bring members together while at the same time separates those that are not members of the respective guilds. The choice of language use by these groups therefore is determined by the ideological orientation of the guilds which seeks to maintain the relevance and supremacy of the group in the larger Ẹdo (Bini) society.
Novel fiber-tip micro flowmeter based on optofluidic microcavity filled with silver nanoparticles solutions
Authors: Li Jinjian , Qu Jian , Liu Yi , Li Yan , Qu Shiliang 
Published: October 2022

Abstract
A novel fiber-tip micro flowmeter based on optofluidic microcavity filled with silver nanoparticles solutions (SNS) is proposed. CW fiber laser was used to heat SNS that can emit heat obviously due to the excellent optic-thermo effect. The heat generated by the silver nanoparticles would be taken away as the microfluidic flows over the fiber microcavity until thermal balance is established under different velocity. The effective refractive index (RI) of the SNS changed followed by temperature of the thermal balance. The dips of the Fabry–Perot interference spectrum shift and the flow velocity can be demodulated. Moreover, the sensor can measure the flow rate with a high sensitivity due to the superior thermal conductivity and specific heat capacity of sidewalls. The max flow rate sensitivity can reach 1.5 nm/(μL/s) in the large range of 0–5 μL/s with a detection limitation (DL) of 0.08 μL/s. The Micron scale probe-type flowmeter has strong robustness and can be used to measure flow rate in tiny space. The heating medium also has an excellent biological compatibility and is not contact with the fluidics directly. As such, we believe that the proposed fiber-tip micro flowmeter has great application potentials in haematology, oil prospecting, ocean dynamics and drug research.

Abstract
Near-field optics is essential in many nanotechnology applications, such as implementing sensitive biosensing and imaging systems with extreme precision. Understanding optical near-fields at the nanoscale has so attracted the considerable research interest, which use a variety of analytical approaches, most notably near-field scanning microscopy. Here, we show defocused point localization mapped accumulation (DePLOMA), which can overcome many weaknesses of conventional analytical methods. DePLOMA is based on imaging fluorescence emitters at an out-of-focal plane. The acquisition, collection, and accumulation of the position and fluorescence intensity of emitters moving above nanostructures can generate three-dimensional near-field maps of light distribution. The idea enables super-resolution liquid-phase measurements, as demonstrated by reconstruction of near-field created by nanoslits with a resolution determined by emitter size. We employed fluorescent emitters with a radius of 50 and 100 nm for confirmation. The axial resolution was found to be enhanced by more than 6 times above that of diffraction-limited confocal laser scanning microscopy when DePLOMA was used.

Forebrain development–an intricate balance decides between health and disease
Authors: Mamo Tamrat Meshka , Hammes Annette 
Published: October 2022

Abstract
Patients carrying pathogenic gene variants encoding factors linked to the sonic hedgehog (SHH) pathway suffer from severe congenital brain malformations including holoprosencephaly (HPE). A poorly understood feature of these common anomalies is the highly variable penetrance, even amongst family members, carrying the same mutation. Modifier genes–genetic variants that can affect the phenotypic outcome of the primary disease-causing gene–contribute to this variability within pedigrees. Modifier genes can confer resilience or susceptibility to a disease, but are difficult to identify in humans. Studying the complex genetic interactions in mouse models of human congenital disorders can be instrumental in the identification of genes, that powerfully modulate SHH signaling pathway capacity and ultimately the penetrance of genetic disturbances. Understanding the underlying complex molecular mechanisms of disease aetiology and can support directing future genetic linkage studies in humans.

Authors: Gupta Samik 
Published: October 2022

Abstract
Coordination polymers (CP) and metal-organic frameworks (MOF) have become a topic of immense interest in this century primarily because of the structural diversity that they offer. This structural diversity results in their multifaceted utility in various fields of science and technology such as catalysis, medicine, gas storage or separation, conductivity and magnetism. Their utility inspires a large variety of scientists to engage with them in their scientific pursuit thus creating a buzz around them in the scientific community. Metals capable of forming CPs and MOFs are primarily transition metals. Among them vanadium-based CPs and MOFs demand detailed discussion because of the unique nature of vanadium which makes it stable in many oxidation states and coordination number. Vanadium’s versatility imparts additional structural marvel and usefulness to these CPs and MOFs.

Published: October 2022

Abstract
In view of the problem that the vibration of the centrifugal impeller of the compressor exceeds the standard when a micro turbojet engine crosses the first-order critical speed, this research proposes a vibration control technology for the engine rotor system based on the new integral squeeze film damper (NISFD) according to the unique structure and assembly characteristics of the rotor bearing seat of the micro turbojet engine. Through numerical analysis and experimental research, the dynamic characteristics of NISFD are analyzed, and the vibration reduction mechanism of NISFD is revealed. The engine test verification based on NISFD is carried out. The results show that NISFD has good damping characteristics, which can improve the bending stress and strain energy distribution of the rotor. The engine test proves that NISFD can well solve the problem of excessive vibration of the engine when passing through the first-order critical speed, greatly reduce the vibration level within the working speed range, and significantly improve the reliability of the engine during operation. It provides a solid theoretical basis for the design of aeroengine, and provides a reference for the practical engineering application of NISFD in aeroengine.
Control of subsonic jets using vanes as vortex generators
Authors: Gandhinathan Balamani , Subramanian Thanigaiarasu 
Published: October 2022

Abstract
The passive control of jets using vanes as vortex generators is studied by numerical simulation in this paper. The vanes are positioned inside the nozzle near the exit, inclined to the flow with the longitudinal direction of the jet. Two configurations namely, straight vanes (k = 0 mm−1) and curved vanes (k = 0.05 mm−1) are considered. Curvature k is defined as the reciprocal of the radius of the vanes. The blockage due to the presence of the vanes is 0.5%. The total pressure variation along the jet centreline and along the radial distance is determined from nozzle exit at a Mach number of 0.4, 0.6 and 0.8. It is found that the vanes cause faster decay of the jet, both in the near field and far field compared to the base nozzle (plain circular nozzle) and the curved vanes perform better than the straight vanes in promoting the jet mixing. A maximum of 54% reduction in jet potential core length is achieved by the curved vanes and the jet becomes asymmetrical due to the presence of the vanes inside the nozzle, as observed in the radial pressure decay plots and Mach number contours.
A Cyclic True Triaxial with Rigid-Rigid-Flexible Boundary for Determination of Cross-Anisotropic Nature of Geomaterials

Published: October 2022

Abstract
This paper describes a custom-designed Soil Poly-Axial Test System, SPAX-3000, developed to investigate the cross-anisotropic material properties of geomaterials under varying loading conditions. SPAX-3000, a mixed-boundary type of large-scale cyclic true triaxial apparatus (CTTA), is capable of applying a wide range of principal stress combinations on prismatic specimens of dimensions 152 × 152 × 304 mm. Two vertical and two horizontal load actuators on two opposite faces apply principal major (σ1) and intermediate (σ2) stresses independently to evaluate the performance of pavement structures under anisotropic stress states through resilient modulus (MR) testing. SPAX-3000 is controlled through software (CATS Software, provided by the manufacturer to provide advanced digital servo control of stresses and deformations). In this study, SPAX-3000 capabilities were evaluated through MR testing of both isotropic (urethane rubber) and cross-anisotropic materials (base, subbase, and subgrade) for the development of stress histories. The test results showed that SPAX-3000 is capable of determining MR independently of the anisotropy characteristics of the tested materials. Stress-hardening and stress-softening behaviors were observed for the coarse- and fine-grained geomaterials under different loading conditions. Anisotropy ratios (ratio of horizontal MR [MhR] to the vertical MR [MvR]) were determined for the base, subbase, and subgrade materials. MR test results showed that higher MvR results were obtained than that of MhR regardless of the loading conditions. The anisotropy ratios ranged from 0.08 to 0.21, 0.38 to 0.87, and 0.05 to 0.50 for the base, subbase, and subgrade materials, respectively. The highest MvR values (200–590 MPa) were obtained for the base material, whereas subbase material yielded the highest MhR (35–169 MPa). In general, stress-hardening behavior was observed for the geomaterials tested in both directions except for the stiffness of subgrade and subbase materials in the vertical direction.
Influence of Particle Size on the Long-Term Resistivity of NaCl-Polluted Sandy Soil
Authors: Sun Funan , Wen Wang , Han Pengju , Bai Xiaohong , He Bin 
Published: October 2022

Abstract
The size of soil particles can change the conducting channels through which an electrolyte solution flows in a soil mass, which has an influence on the tortuosity of pores in soil mass, thus further changing the conductivity of the soil mass. By carrying out laboratory tests, the influences of moisture and particle size of sandy soil on the resistivity of sandy soil polluted with sodium chloride were evaluated. Furthermore, the models for analyzing relationships linking the resistivity of sandy soil polluted with sodium chloride with moisture and particle size of sandy soil under experimental conditions were separately established. The test results showed that the resistivity of sandy soil polluted with sodium chloride at different moisture contents linearly decreases with increasing particle size. Based on the Archie resistivity model, the influence of particle size on the resistivity of polluted sandy soil was explored by carrying out laboratory tests. On this basis, the formula (ρ = [(3 − 2ω)(3ω − 35)][(ω + 3) + g]) for predicting the resistivity of polluted sandy soil with changes in moisture content and the particle size of the system of sandy soil is established, where ω, g, and ρ separately refer to the moisture content, particle size, and resistivity of the system, respectively. Finally, by analyzing the influence of particle size on tortuosity, a resistivity model (ρ=Aρωτe(θ)θ) for analyzing the influence of tortuosity on the resistivity of sandy soil is established, where τe(θ), θ, and ρω separately refer to tortuosity, porosity, and resistivity of pore water, respectively.
