Abstract
Background Anaemia during pregnancy could cause adverse outcomes to the woman and the foetus, including anaemic heart failure, prematurity, and intrauterine growth retardation. Iron deficiency is the leading cause of anaemia and oral iron supplementation during pregnancy is widely recommended. However, little focus is directed to dietary intake. This study estimates the contribution of iron deficiency among anaemic pregnant women and examines risk factors including dietary risk factors for iron deficiency anaemia (IDA) in pregnant women with moderate or severe anaemia in Lagos and Kano states, Nigeria.Methods In this cross-sectional study, 11,582 women were screened for anaemia at 20–32 weeks gestation. The 872 who had moderate or severe anaemia (haemoglobin concentration < 10g/dL) were included in this study. Iron deficiency was defined as serum ferritin level < 30ng/mL. We described the sociodemographic and obstetric characteristics of the sample and their self-report of consumption of common food items. We conducted bivariate and multivariable logistic regression analysis to identify risk factors associated with IDA.Results Iron deficiency was observed among 41% (95%CI: 38–45) of women with moderate or severe anaemia and the prevalence increased with gestational age. Any consumption of green vegetables was found to be associated with a 64–74% reduction in odds for IDA compared to non-consumption (aOR: 0.26–0.36, p < 0.05). Daily consumption of edible kaolin clay was associated with increased odds of having IDA compared to non-consumption, aOR 9.13 (95%CI: 3.27–25.48). Consumption of soybeans three to four times a week was associated with higher odds of IDA compared to non-consumption, aOR: 1.78 (95%CI: 1.12–2.82).Conclusion About 4 in 10 women with moderate or severe anaemia during pregnancy had IDA. Our study provides evidence for the protective effect of green leafy vegetables against IDA while self-reported consumption of edible kaolin clay and soybeans appeared to increase the odds of having IDA during pregnancy. Health education on diet during pregnancy need to be evaluated since this could potentially increase awareness and change behaviours that could reduce IDA among pregnant women with moderate or severe anaemia in Nigeria and other countries.

Abstract
Background Hepatitis B infection remains a major cause of chronic liver disease worldwide, which exerts substantial pressure on global public health security. Recent studies have demonstrated that T cell-mediated cellular immune mechanisms are important in hepatitis B progression. Oxidative stress is also an important background of numerous liver disorders, but the connections between numbers and oxidative stress of T cells remain unclear in hepatitis B.Purpose To assess the characterizations and changes of peripheral blood T lymphocytes and their mitochondrial reactive oxygen species in hepatitis B development.Methods We recruited 432 patients with hepatitis B (144 with mild disease, 165 with moderate and severe disease, 90 with compensated cirrhosis, 33 with decompensated cirrhosis) and 65 healthy people (controls) to the study. Mitochondrial damage was detected by flow cytometry with a specific probe. The immune levels of specific immune cells and T cell mitochondrial functions were evaluated with the relative and absolute counts of T lymphocyte subsets.Results Patients with hepatitis B had higher mitochondrial damage indexes, which increased with disease progression. The patients also had lower absolute CD3+, CD4+, and CD8+ T lymphocyte counts compared with the controls (p < 0.05), where the counts decreased with disease progression. The absolute CD8+ T cell counts were negatively correlated with the mitochondrial damage indexes (p < 0.05, r = -0.11), but there were no correlations between the absolute CD4+ T cell counts and the mitochondrial damage indexes. Furthermore, the absolute T cell counts had a weakly positive correlation with the liver injury index, but the T cell mitochondrial damage indexes were not correlated with the liver injury index.Conclusions These data suggested that the mitochondrial damage frequencies and T lymphocyte subset levels differed between the different phases of chronic HBV infection, and decreased lymphocyte subsets might be related to the increased mitochondrial damage indexes in hepatitis B patients. The abnormal change in mitochondrial function and lymphocyte subsets might be important in hepatitis B development, but the underlying mechanisms remain ambiguous.

Published: May 2023

Abstract
The generalised Hopf equation is the first order nonlinear equation defined on a planar domain Ω ⊂ C, with data Φ a holomorphic function and η ≥ 1 a positive weight on Ω, hw hw η(w) = Φ. The Hopf equation is the special case η(w) = ˜η(h(w)) and reflects that h is harmonic with respect to the conformal metric p η˜(z)|dz|, usually η is the hyperbolic metric. This article obtains conditions on the data to ensure that a solution is open and discrete. We also prove a strong uniqueness result.
Life-course Transition as a Determinant of Migration: A Scoping Review
Authors: Narayan Akhila Chakshu , Chakraborty Rituparna 
Published: May 2023

Abstract
This scoping review analyses life-course transition as a determinant of migration. Migration paired with life-course transitions has been analysed from developmental psychology and life course perspectives. The context of the review is limited to the contemporary industrialized globalized developed and developing societies in which migration has become prevalent. This review analysed the alignment of life course transition stages and migration, delving into its possible explanations. An increase of migration within emerging adulthood is brought out. The review follows PRISMA guidelines, and the final protocol was registered at Open Science Framework’s open-access registry. The review found that most migrations are aligned with developmental life course transition events, like progression from school to higher education, college to work, or from work to retirement. Steadily increasing migration within the period of emerging adulthood has been identified as being relevant to the psychosocial developmental relevance within the life-course. In addition, the review also indicates that although the mental health and well-being of migrating individuals need consideration at all ages, older adults are at higher risk of both physical and mental health complications.
On Discerning Between Mixtures of Linearly Polarized Photons using the Hong-Ou-Mandel Effect and Heralding Photon
Authors: Troyansky Lidror 
Published: May 2023

Abstract
The Hong, Ou, and Mandel (HOM) effect allows to assess the similarity between the polarization of two (otherwise identical) photons that enter a beam-splitter from two different ports at the same time, without obtaining information regarding the absolute polarization. This report presents new methods that utilize the HOM effect with three photons to discern between mixtures of polarized photons. When one photon is detected in one port of the beam splitter, it heralds that the two other photons are likely to be identical. The resulted polarization statistics can be utilized to discern between mixed states of polarized photons that cannot be discerned by previous methods.
Mating alters the food choices of adult ladybird beetle (Propylea dissecta Mulsant)
Authors: Verma Lata , Mishra Geetanjali , Omkar Omkar 
Published: May 2023

Abstract
Mating alters nutritional and energetic needs which results in behavioural and physiological changes related to reproduction. But little is known as to how mating influences sex specific food preferences in ladybird beetle, Propylea dissecta. To explore this, 10-day old adults were subjected to different time mating interruption treatments, i.e., no mating, 30, 60, 90, 120, 150, 180 minutes and complete mating (211 ± 8.1 min) and post mating they were then provided with food choice (i.e., Aphis craccivora, conspecific eggs, and heterospecific eggs) separately in Petridish. Results show that on increase in mating duration females showed altered food choice whereas it was found to be insignificant in males. However, in both the sexes time to consume first prey was decreased on increase in mating duration possibly to cope up high energy expenditure and to fulfil their instant food requirements. Our results indicate that mating modulates sex-specific food preference in ladybird beetle, P. dissecta.

AbstractEomecon chionanthaHance (EC) is a unique species in China with high medicinal value. Ethnic minorities in China, such as the Miao and Tujia ethnic groups, have a long history of using blood herbs for treatment, andEChas been used for this purpose for centuries. However, despite its long history of use, we have no knowledge of the chloroplast genome ofECTherefore, this study reportsEC's complete chloroplast genome information to better develop and protect this unique plant species in China. The complete chloroplast genomic information indicates thatEC's chloroplast DNA (CPDNA) (178,808 bp) contains 99 protein-coding genes, including 8 rRNAs, 37 tRNAs. We have discovered 54 SSRs, most of which are single nucleotide adenine-thymidine (A-T) repeats. Comparative analysis of codons, repeats, and genomic sequences have found that the CPDNA ofECis highly conserved. According to our phylogenetic tree results,ECis closely related to four species. Through K2-P analysis, we have identified five hypervariable regions, includingycf4-cemA,ycf3-trnS-GGA,trnC-GCA-petN,rpl32-trnL-UAG, andpsbI-trnS-UGA. In summary, this study has reported, for the first time, the complete chloroplast genome of the unique single genus plantECin China. This provides a more scientific basis for further development and utilization of this species and is conducive to an in-depth understanding of plant species diversity from a genomic perspective.

Published: May 2023

Abstract
Nonlinear tracking control enabling a dynamical system to track a desired trajectory is fundamental to robotics, serving a wide range of civil and defense applications. In control engineering, designing tracking control requires complete knowledge of the system model and equations. We develop a model-free, machine-learning framework to control a two-arm robotic manipulator using only partially observed states, where the controller is realized by reservoir computing. Stochastic input is exploited for training, which consists of the observed partial state vector as the first and its time-delayed copy as the second component so that the neural machine regards the latter as the future state of the former. In the testing (deployment) phase, the time-delayed component is replaced by the desired observational vector from the reference trajectory. We demonstrate the effectiveness of the control framework using a variety of periodic and chaotic signals, and establish its robustness against measurement noise, disturbances, and uncertainties.
Generalizing Frobenius Inversion to Quaternion Matrices
Authors: Chen Qiyuan , Uhlmann Jeffery , Ye Ke 
Published: May 2023

Abstract
In this paper we derive and analyze an algorithm for inverting quaternion matrices. The algorithm is an analogue of the Frobenius algorithm for the complex matrix inversion. On the theory side, we prove that our algorithm is more efficient that other existing methods. Moreover, our algorithm is optimal in the sense of the least number of complex inversions. On the practice side, our algorithm outperforms existing algorithms on randomly generated matrices. We argue that this algorithm can be used to improve the practical utility of recursive Strassen-type algorithms by providing the fastest possible base case for the recursive decomposition process when applied to quaternion matrices.
Red cell distribution width to albumin ratio is a risk factor for atrial fibrillation in general population
Authors: Song Yanbin , Li Wenhua 
Published: May 2023

Abstract
Background: Red cell distribution width to albumin ratio (RAR) has been demonstrated to be associated with the risk of cardiovascular diseases. However, it is still unknown whether the RAR affects atrial fibrillation (AF) . Therefore, this study aimed to investigate the association between RAR and AF in general population.
Methods: A total of 2436 participants were retrospectively enrolled. Red cell distribution width, albumin and other data were collected. AF was confirmed using 12-lead electrocardiogram (ECG) or 24-hour Holter. All participants were divided into four groups according to the RAR values by quartile (Q1, Q2, Q3, Q4). Univariate and multivariate logistic regression were performed to examine the correlation between RAR and AF.
Results: Among the 2436 participants, 227 (9.3%) AF cases were observed. The RDW and RAR were significantly higher in AF group than in non-AF group (all P<0.001). Univariate logistic regression showed an positive association between RAR and AF (P<0.001). In multivariate logistic regression, RAR was found to be an independent risk factor of AF after adjusting for confounding factors (OR:2.015, 95%CI:1.315-3.089, P=0.001) .
Conclusions: The present study indicated that elevated RAR level was independently correlated with increased risk of AF in general population.
The [k]-multiple Roman domination in Graphs
Authors: Valenzuela-Tripodoro J. C. , Mateos-Camacho M. A. , Cera M. , Alvarez-Ruiz M. P. 
Published: May 2023

Abstract
In 2016, Beeler et al. introduced the double Roman domination as a variation of Roman domination and recently Abdollahzadeh et al. (resp. Amjadi et al.) initiated the study of triple (resp. quadruple) Roman domination in graphs. Given any labeling of the vertices of a graph, AN(v) stands for the set of neighbors of a vertex v having a positive label. In this paper we generalize these concepts by studying the [k]-multiple Roman domination functions ([k]-MRDF) in graphs which coincides with the previous versions when 2 ≤ k ≤ 4. Namely, f is a [k]-MRDF if f(N[v]) ≥ k + |AN(v)| for all v. We approach the complexity of the associate decision problem and we also give sharp bounds and exact values for several classes of graphs.

Published: May 2023

Abstract
Perilla frutescens L. is a kind of phenolic acids riches plant. Rosmarinic acid (RA) is the main phenolic acid component in perilla. It has various pharmacological activities such as anti-allergic, anti-inflammatory, and antioxidant. In this study, the hairy roots culture of Perilla was established from leaves explants using Agrobacterium rhizogenes C58C1, A4, R1000, and the content of phenolic acids was also determined. The highest RA content in the five obtained fast-growing lines reached 19.08mg/g (DW). The effects of salicylic acid (SA) and methyl jasmonate (MeJA) treatment on phenolic acids (Protocatechuic aldehyde, caffeic acid, ferulic acid, RA, and ethyl caffeic acid ) accumulation in hairy roots were also investigated. SA can promote phenolic acid accumulation; the content of RA reached 20.92 mg/g (DW) on day nine after treatment. MeJA can upregulate the RA content to 17.36mg/g (DW) on day three, and then the RA content declined to 4.27mg/g (DW) on day 9. These results showed the high potential of perilla hairy roots to produce phenolic acids. It would be an efficient method for the large-scale production of RA in P. frutescens.

Authors: Puente Héctor , Arguello Héctor , Cortey Martí , Gómez-García Manuel , Mencía-Ares Oscar , Pérez-Perez Lucía , Díaz Ivan , Carvajal Ana 
Published: May 2023

Abstract
Background:
The aim of this work was to study the prevalence and distribution of Porcine astrovirus (PAstV), Porcine kobuvirus (PKoV), Porcine torovirus (PToV), Mammalian orthoreovirus (MRV) and Porcine mastadenovirus (PAdV) as well as their association with widely recognized virus that cause diarrhoea in swine such as coronavirus (CoVs) and rotavirus (RVs) in diarrhoea outbreaks from Spanish swine farms. Furthermore, a selection of the viral strains was genetically characterized.
Results:
PAstV, PKoV, PToV, MRV and PAdV were frequently detected. Particularly, PAstV and PKoV were detected in almost 50% and 30% of the investigated farms, respectively, with an age-dependent distribution; PAstV was mainly detected in postweaning and fattening pigs, while PKoV was more frequent in sucking piglets. Viral co-infections were detected in almost half of the outbreaks, combining CoVs, RVs and the viruses studied, with a maximum of 5 different viral species reported in three investigated farms.
Using a next generation sequencing approach, we obtained a total of 24 ARN viral genomes (>90% genome sequence), characterizing for first time the full genome of circulating strains of PAstV2, PAstV4, PAstV5 and PToV on Spanish farms. Phylogenetic analyses showed that PAstV, PKoV and PToV from Spanish swine farms clustered together with isolates of the same viral species from neighboring pig producing countries.
Conclusions:
Although further studies to evaluate the role of these enteric viruses in diarrhoea outbreaks are required, their wide distribution and frequent association in co-infections cannot be disregard. Hence, their inclusion into routine diagnostic panels for diarrhoea in swine should be considered.
Deformation prediction and experimental investigation on alternating additive-subtractive hybrid manufacturing of 316L stainless steel thin-walled parts

Published: May 2023

Abstract
The additive-subtractive hybrid manufacturing (ASHM) technology has become a research hotspot in recent years. In order to realize high-precision manufacturing of complex parts and avoid machine interference, the alternating additive manufacturing (AM) and subtractive manufacturing (SM) are valuable to be adopted. In this paper, the finite element numerical model was developed to simulate the temperature, stress distribution and deformation of the alternating ASHM thin-walled parts after the AM process and the subsequent milling process. Then, 316L stainless steel thin-walled samples were built by alternating ASHM. In AM process, the molten pool temperature was measured by a colorimetric pyrometer. And the surface contour of the sample was adopted by a laser distance sensor after each AM and SM operation. The results show that higher tensile stress is exhibited at the top and bottom of the AM segments, and the residual stress level decreases after the subsequent milling due to stress relaxation. Moreover, the deformation of the two ends and the top of the AM segments is more significant than that of the bottom. After SM, the deformation of the top of the SM segments is still slightly more extensive than that of the bottom. The next AM segment has little effect on the deformation of the upper SM segment, but has a destructive impact on the interface between the SM and upper AM segment. The repeated cutting height between the SM and upper AM segment was studied. This study may offer valuable guidance for 316L thin-walled parts fabricated by alternating ASHM.
Mapping the flood hazard potential of small watercourses in a mountain river basin
Authors: Solín Ľubomír , Madajová Michala Sládeková , Michaleje Lukáš 
Published: May 2023

Abstract
The aim of this study is to present a methodological approach for the mapping of the flood hazard potential of small watercourses, based on their hydromorphogical attributes on the example of a mountain river basin in Slovakia. The flood hazard of a watercourse is understood more comprehensively and includes a set of watercourse attributes that are pressure indicators that affect the flood hazard. The proposed procedure consists of several steps: from the selection of watercourse variables influencing flood hazard potential through to the evaluation of the attributes of the variables in terms of their impact on flood hazards and the determination of the flood hazard index. The mapping divides the watercourse into reaches that differ by their level of flood hazard potential. This enables to identify those river reaches that are critical in terms of flood hazard and where management interventions are needed. The interpretation of the achieved results on the flood hazard of river reaches is carried out in the context of cadastral areas through which watercourses flow. It is considered to be particularly important and beneficial for local authorities.
Context modulates perceived fairness in altruistic punishment: Neural signatures from ERPs and EEG oscillations
Authors: Yang Lei , Gao Yuan , Ao Lihong , Wang He , Liu Yingjie 
Published: May 2023

Abstract
Social norms and altruistic punitive behaviours are both based on the integration of information from multiple contexts. Individual behavioural performance can be altered by loss and gain contexts, which produce different mental states and subjective perceptions. In this study, we used event-related potential and time-frequency techniques to examine performance on a third-party punishment task and to explore the neural mechanisms underlying context-dependent differences in punishment decisions. The results indicated that individuals were more likely to reject unfairness in the context of loss (vs. gain) and to increase punishment as unfairness increased. In contrast, fairness appeared to cause an early increase in cognitive control signal enhancement, as indicated by the P2 amplitude and theta oscillations, and a later increase in emotional and motivational salience during decision-making in gain vs. loss contexts, as indicated by the medial frontal negativity and beta oscillations. In summary, individuals were more willing to sanction violations of social norms in the loss context than in the gain context and rejecting unfair losses induced more equity-related cognitive conflict than accepting unfair gains, highlighting the importance of context (i.e., gain vs. loss) in equity-related social decision-making processes.
