An econophysical and system dynamical analysis of the cross-price elasticity and the price elasticity of demand by Bishop as key factors to determine the market structure of an industry
Authors: Franck Oliver 
Published: February 2023

Abstract
A precise understanding of the market structure of an industry forms the basis for any entrepreneurial decisions. The combination of Bishop's cross-price elasticity of demand and price elasticity of demand forms the mathematical basis for determining the market structure. However, these formulas are time-independent, which does not adequately capture the complex dynamics of today's economy. This paper attempts a systemic dynamic extension of the cross-price elasticity of demand and the price elasticity of demand by adding a temporal dimension to these formulas. This ensures that entrepreneurial and industry-specific decisions can be made more accurately by following a system-dynamic approach. This paper provides a methodological extension based on Estola's econophysical theory and combining it with Bishop’s approach for determining the market structure of an industry. Econophysics ensures that the temporal dimension is taken into account in economic formulas and therefore providing a more accurate view on current economic issues.

Abstract
Studies examining the association between type 1 diabetes (T1D) and atopic diseases, i.e., atopic dermatitis, allergic rhinitis and asthma have yielded conflicting results due to different algorithms for classification, sample size issues and risk of referral bias of exposed groups with frequent contact to prescribers. Using Danish national registries and well-established disease algorithms, we examined the bidirectional association between T1D and atopic diseases in childhood and adolescence using Cox Proportional Hazard regression compared to two different unexposed groups from a population of 1.5 million Danish children born from 1997–2018. We found no associations between T1D and atopic dermatitis, allergic rhinitis, or asthma (defined after age five). However, in multivariate analysis we found an increased risk of persistent wheezing (defined as asthma medication before age five) after T1D with an adjusted Hazard Ratio (aHR) of 1.70 [1.17–2.45]. We also identified an increased risk of developing T1D after persistent wheezing with aHR of 1.24 [1.13–1.36]. This study highlights similar risks of atopic diseases in children with T1D and of T1D in children with atopic disease after age of five years versus healthy controls, however more research is needed to understand the possible early immunological effects of the link between persistent wheezing and T1D.

Abstract
In this research article, we have extracted simple closed form resolutions containing the variables and some parameters of the Lonngren wave equation and the (2 + 1)-dimensional stochastic Nizhnik-Novikov-Veselov system pressed in the Ito sense by augmentative noise. The acquired solutions of the Lonngren wave equation and the (2 + 1)-dimensional stochastic Nizhnik-Novikov-Veselov system may be effective to explore the electromagnetic signals in any cable lines and sound wave in any stochastic system respectively. For the required solutions, we use here the two variables (G1⁄G, 1/G)-expansion method and we notice the obtained solutions are ascertained in terms of trigonometric function, hyperbolic function, and rational function types. By taking the parameters as some special values, we see that the obtained solutions graphically imply the soliton solutions like as, singular solition, singular periodic solution, bell shape soliton and anti-bell shape soliton which all are added in the ultimate part of this paper.

Abstract
This research work demonstrates an approach to solve nonlinear evolution equations via the generalized \(\left(G{\prime }/G\right)\)-expansion method which is an advantageous mathematical tool for establishing abundant solutions of these types of nonlinear evolution equations. Here, we select the \(\left(1+1\right)\)-dimensional integro-differential Ito equation and \(\left(2+1\right)\)-dimensional integro-differential Sawda-Kotera equation to extract the closed traveling wave solutions by using the mentioned method. In applied Mathematics, mathematical Physics, engineering science as well as real time application fields have enormous application of these type of equations. The new traveling wave solutions derived by this method are involving hyperbolic function, trigonometric function and rational function. This method is direct, efficient, convenient and powerful to solve other nonlinear evolution equations. Moreover, the features of the solutions are illustrated by some figures.
Effect of Stability of Hexagonal Honeycomb Plate Girders on Shear Strength: Analytical Study
Authors: Shaffaf Noora N. , Ammash Haider K. 
Published: February 2023

Abstract
Shear behavior of two full scale honeycomb steel plate web girders that were modeled in finite element program was numerically studied. All girders were created with 0.30mm steel plate thickness and 20mm outside thickness of corrugated web. The girders were numerically loaded for an intermediate stiffeners to depth ratio (a/d) equal to 1%. The performance of plate web girder was improved through enhancement shear strength. The thin webs was strengthen by using corrugations system. Four cells of hexagonal honeycomb web were constructed to form the web cross section of such girder. One concentrated load was applied at mid span up to failure. The behavior of the shear girders was studied through reporting failure load values, shear buckling failure modes, maximum mid span deflections and load-displacement relationships. The numerical shear buckling strength of the girders were compared with theoretical value of the flat web girder. The finite element results showed that in general using honeycomb corrugated steel plate increased slightly the shear capacity of the girders compared with the flat web girder. Furthermore, the stability of honeycomb steel plate girder can be enhanced when more than one cell in honeycomb section was used which can increase the shear buckling strength regardless of the shear span to depth ratio.

Abstract
Background
In Crohn's disease (CD), the inability to intubate the ileocecal valve during colonoscopy may be associated with a poor disease prognosis. In this study, we aimed to compare the long-term outcomes of CD patients with and without ileocecal valve intubation during colonoscopy to assess its value as a prognostic parameter.
Methods
This retrospective study involved CD patients with isolated ileal involvement who underwent colonoscopy between 1993 and 2022. We compared the basic characteristics and long-term clinical outcomes of two groups of patients: those with intubated and non-intubated ileocecal valves during colonoscopy.
Results
Of the 155 participants, 97 (62.5%) patients’ ileum could be intubated and 58 (37.5%) could not be intubated. The non-intubated group was older at diagnosis (39 years versus 30.5 years, p =0.002), but other baseline characteristics such as sex, smoking status, disease duration, perianal disease, and upper gastrointestinal involvements were similar. The non-intubated group had higher rates of steroid dependence (67.2% versus 46.4%; p =0.012), biologic treatment (89.7% versus 58.8%; p <0.001), CD-related hospitalization (81% versus 24.7%; p <0.001), and major abdominal surgery (58.6% versus 15.5%; p <0.001).
In the logistic regression analysis, the positive predictors of successful ileum intubation were inflammatory type CD (OR: 14.821), high serum albumin level (OR: 5.919), and older age (OR: 1.069), while the negative predictors were stenosing (OR: 0.262) and penetrating (OR: 0.247) CD behavior.
Conclusions
Crohn's disease patients with isolated ileal involvement, ileocecal valve cannot be intubated during colonoscopy may indicate the severity of the disease.
Conflict Resolution between Multi-Level Government and Farmers in Land Expropriation Based on Institutional Credibility Theory: Empirical Evidence from Shandong Province, China

Published: February 2023

Abstract

The land expropriation policy of Merging Villages & Living Together (MVLT) in rural areas has intensified conflicts due to insufficient financial compensation and "demolishing old houses before building new ones". The current research rarely includes farmers, governments at all levels, the strength of policy tools, and policy perceptions into a unified quantitative research framework.This paper adopts the institutional credibility theory, incorporates the policy instruments of higher-level governments, administrative instruments of lower-level governments, and farmers' credibility of policies into a unified accounting framework, constructs a conflict stress index, evaluates the role of each subject's characteristics, policy perceptions, and policy instruments in the process of conflict generation and resolution, and analyzes the ways of conflict resolution from the perspective of different stakeholder games. The analysis framework are verified by using the case study of MVLT policy in Shandong Province, China.The results show that the credibility of the policy is influenced by individual characteristics and varies significantly. The administrative means and different combinations of the lower level government can significantly improve the success rate of policy implementation. The highest value of the conflict index was observed when the administrative instruments reached the maximum value without marginal increase in farmers' credibility for policy implementation and improvement were made.

Published: February 2023

Abstract
Purpose: To explore the characteristics and risk factors of the joint incidence of Tuberculosis, Hepatitis B, and AIDS at the provincial level in China.
Methods: A Bayesian hierarchical spatio-temporal model of multiple diseases is established. The shared components are used to identify diseases with similar spatio-temporal patterns, and specific components explain the specific spatio-temporal patterns of each disease. Finally, the integrated nested Laplace approximation algorithm is used to estimate the posterior mean of each effect parameter.
Results: Tuberculosis and Hepatitis B have more similar shared space mode, and the shared space effect has the highest impact. The shared time risk of the three diseases has little change on the whole, and the change of specific time relative risk and combined time relative risk is quite different. Among them, the combined time relative risk of tuberculosis is almost constant, Hepatitis B first and then stabilizes, and AIDS shows a trend of increasing first and then decreasing.
Conclusion: The geographical environment factors may be used as a replacement for the shared Spatial effect. It has a more significant impact on the onset of Tuberculosis and Hepatitis B and has a negligible impact on the onset of HIV. In addition, some risk factors, such as economy and policy, may have different time effects on these three diseases.
Upstream water management and its role in estuary health, evaluation of freshwater management and subtropical estuary function
Authors: Julian Paul , Reidenbach Leah 
Published: February 2023

Abstract

In highly modified and managed systems the balance of freshwater inputs discharged to estuarine systems are important to maintain salinity balances and thus estuarine function. However, the availability of freshwater is highly dependent on upstream water management to provide flood protection whilst meeting freshwater demand for people and the environment. In South Florida, water is managed by a water control plan with Lake Okeechobee at the center. Currently, water levels within the lake are managed based on the Lake Okeechobee Regulation Schedule of 2008. The new regulation schedule, Lake Okeechobee System Operating Manual (LOSOM), updates water management rules while attempting to balance the needs of downstream systems; salinity and water quality in the Caloosahatchee and Saint Lucie (northern) estuaries; and more water for the southern Everglades. This study evaluates LOSOM relative to ecologically significant performance measures for the northern estuaries. Overall the proposed regulation schedule is expected to provide a more sustainable flow regime to the estuaries by reducing stressful and damaging discharge events. Moreover, new management rules combined with new infrastructure are expected to reduce low discharge events to the Caloosahatchee estuary and reduce stress on key indicator species such as Vallisneria americana during the wet season. This regulation schedule provides improved conditions for the estuaries, but Lake Okeechobee carries the burden. Future restoration and water management strategies are needed to maintain the benefits afforded to the estuaries while at the same time reducing the stress and damage to Lake Okeechobee to develop a more sustainable and resilient system.
Genesis of Mesozoic high-Mg dioritic rocks from the eastern North China Craton: Implications for the evolution of continental lithosphere
Authors: Guo Jun , Huang Xiao-Long , He Peng-Li , Chen Lin-Li , Zhong Jun-Wei 
Published: February 2023

Abstract
Pre-Cenozoic high-Mg andesites (HMAs) are mostly present in continental interiors, but their genetic relationship with continental lithosphere evolution remains unclear because of uncertainties of their mantle source, magmatic processes, and physicochemical conditions of formation. Early Cretaceous high-Mg dioritic rocks (HMDs, analogs of HMAs) of the Jinling complex in the Luxi area are typical intra-plate intrusions of the eastern North China Craton (NCC) and can be subdivided into two groups (Group-I and -II) on the basis of their petrographic and geochemical features. Group-I HMDs show low SiO2 contents (52.47–56.10 wt%) and Sr/Y (34.5–39.6) and (La/Yb)N (10.3–13.6) ratios but high contents of MgO (7.86–9.13 wt%), Y (18.3–20.3 ppm), Yb (1.43–1.47 ppm), and compatible elements (Cr = 407–585 ppm; Ni = 117–216 ppm), classifying as sanukitic rocks. Group-II HMDs are characterized by high SiO2 contents (63.81–64.87 wt%) and Sr/Y (47.1–63.4) and (La/Yb)N (16.1–17.5) ratios with low MgO (2.90–3.08 wt%), Y (0.88–1.04 ppm), Yb (0.88–1.04 ppm), and compatible elements (Cr = 201–213 ppm; Ni = 55–57 ppm) contents, belonging to adakitic rocks. Group-I and Group-II HMDs of the Jinling complex are closely related in spatial and temporal distribution, and all have enriched Sr-Nd isotopic compositions and arc-like trace element patterns with abundant hydrous minerals. Therefore, the Jinling HMDs should share a common source of ancient sub-continental lithospheric mantle that was metasomatized by aqueous fluids derived from the subducted Paleo-Pacific slab. The Jinling HMDs were not formed from interaction between slab-derived melts and mantle-wedge peridotites but were instead derived from partial melting of hydrous mantle peridotites in the continental interior of the eastern NCC. The distinctly different petrography, geochemistry, and mineralogy of the two groups of rocks resulted mainly from differing magmatic processes at crustal depths. Thus, Pre-Cenozoic intra-plate HMAs/HMDs are genetically distinct from Cenozoic HMAs that were mostly present in arc settings and generally represent juvenile crust growth. In a way, Archean tonalitic-trondhjemiticgranodioritic rocks (TTG) and sanukitoids, geochemically similar to HMAs/HMDs, could also be derived from interaction between slab-derived melts and mantle-wedge peridotites in arc settings or partial melting of hydrous mantle peridotites in continental interiors, and thus might not always be related with continental crustal growth and the onset of plate subduction.

Published: February 2023

Abstract
Membrane filtration technology is widely applied in conventional surface water treatment plants because of its low power load and high filtration accuracy. This study follows the transition from a power-driven to a gravity-driven siphon-submerged ultrafiltration membrane system in a drinking water treatment plant in Shandong Province, China. The proportion of space membrane areas in the tank was further developed, by increasing the membrane areas of a single tank to 1.6 times that before the transformation, and the design production capacity of a single tank is increased from 10,000 m3/d before the transformation to 16,700 m3/d. The recovery rate of a single tank was also increased from 96.28 to 97.77%. The energy consumption per ton of water decreased from 0.06 to 0.017 MJ. The annual carbon emissions reduction reached 197.13 tons per tank. In terms of the water quality, the algae removal rate from surface water by the ultrafiltration membrane reached 100%. Further, the removal rates of 2 μm particles, turbidity, and chlorophyll were above 99%. Our results suggest that gravity-driven siphon-submerged ultrafiltration promotes environmental protection, energy conservation, and emissions reduction. This technology introduces a new development direction for membrane filtering in drinking water treatment plants.
Expression and Clinical Significance of PIEZO2 in Gastric Cancer
Authors: Liang Tong , Da Ming-Xu 
Published: February 2023

Objective:
The aim of this research was to investigate the expression of PIEZO2 and its
potential clinical significance in gastric cancer (GC).

Methods:
In this study, we detected the protein expression levels of PIEZO2 in GC tissues and adjacent
normal tissues by immunohistochemistry (IHC) and analysed the relationship between the
protein expression levels of PIEZO2 and clinicopathological parameters of GC patients. Gene Expression
Profiling Interactive Analysis (GEPIA) and Kaplan–Meier Plotter were used to verify the
diagnostic and prognostic values of PIEZO2. Proteins interacting with PIEZO2 were predicted using
the SRING database.

Results:
Our results showed that the protein expression levels of PIEZO2 in GC tissues were lower
than those in adjacent normal tissues (all P < 0.05), and the protein expression level of PIEZO2
was correlated with lymph node metastasis and TNM stage of GC patients (all P < 0.05). Aberrant
overexpression of PIEZO2 was associated with poor prognosis of GC patients. Proteins such as
VR1, TRPV1, LHFPL5, STOM, TRPA1 and STOML3 had obvious interactions with PIEZO2 (P =
0.00213).

Conclusion:
In summary, our current study identified PIEZO2 as a promising target for early diagnosis
and as a potential prognostic biomarker in GC patients.

Asthma in South Indian Population
Authors: Maheswarappa Mahendra , Basavaraju Manjula , Bhaktha Geetha , Anand Mahesh P. , Seetharama Nagabushan 
Published: February 2023

Background:
Asthma is an important cause of morbidity worldwide. The FOXO3a gene plays an important role in human immune regulation and homeostasis. Loss of function may lead to chronic inflammation and asthma.

Objective:
To evaluate the association between Foxo3a gene polymorphism and susceptibility to asthma.

Methods:
We conducted a case-control study in a tertiary care hospital. Participants answered a questionnaire that collected demographic and clinical information. Asthma was confirmed by pre and post bronchodilator spirometry. Genotyping of the FOXO3a polymorphisms was performed us-ing PCR-RFLP.

Results:
The study population included 41 cases and 33 controls. Among cases, the heterozygous (CT) genotype frequency was greater compared to wild homozygous (CC) and mutant homozygous (TT) variants. In controls, the wild homozygous (CC) genotype frequency was greater compared to heterozygous and mutant homozygous variants. In the general model, the mutant homozygous (TT) group had significantly higher odds of 7.8 (1.78-34.07) of having asthma compared to the wild ho-mozygous (CC) group. The mutant homozygous (TT) group had greater severity of asthma as com-pared to the wild homozygous (CC) group. The mutant homozygous group (TT) had much lower lung functions, as compared to the wild homozygous (CC) group in asthmatics. Among non-asthmatic controls, lower lung functions were seen in the mutant (TT) group as compared to the wild (CC) group.

Conclusion:
We found a significant association between the Foxo3a gene polymorphism and asth-ma. The T allele, a variant of the Foxo3a gene polymorphism, is associated with a higher risk of asthma, and greater asthma severity. It is also associated with lower lung functions in both asthmat-ics and apparently healthy control subjects.
