A meshless P1-Lagrange Interpolation operator in Rd
Authors: benmensour Khadidja , pousin jerome 
Published: April 2023

Abstract
Generally, meshless interpolations are not polynomial, in this paper, we propose a meshless polynomial local interpolator. This interpolator uses Lagrange polynomials P1 and a nearest neighbors strategy, and have yet been introduced in a previous work [1] investigating the relation between an artificial neural network and the transport of the identity towards a given function to be interpolated. Unfortunately, it has been reported in [1] that the order of convergence of the interpolation deteri- orates when the size of the d-simplexe becomes too small, because the built d-simplexe does not necessary contain the point at which inter- polation is computed. The aim of this note is to remedy this difficulty. Here, we study the problem of interpolating d-dimensional data with P1 polynomials by minimizing a data-fidelity cost function, involving the barycentric coordinates of the d + 1-nearest neighbors. Data points dis- tributions are not required to be structured, and the nearest neighbors are computed through a penalized minimization process in order to get a no degenerate d-simplex containing the point at which the interpolation is computed. The proposed interpolation operator is local, and a global one can be built which will be no more polynomial. Some numerical results are provided showing the efficiency of the proposed method.

Abstract
In this article, we investigate the S-wave of Ω0c baryon in the relativistic Dirac formalism. The spectroscopy is performed using the independent quark model(IQM). The spin-average masses are obtained by summing the individual Dirac energies of the constituent quarks under the mean field confinement of Martin-like potential with a parametric center of mass correction. We find the spin-average masses of low-lying S-wave and the spin degeneracy is removed by considering the spin-spin (j · j) interactions. The best-fitted potential parameters yielded the estimation of the ground state masses in very good agreement with experimental data. The computed masses of 1S( 3/2+), 2768.84 MeV and 1S( 1/2+), 2698.14 MeV are very close to the experimentally observed states. We also predict the experimentally observed state Ω0C(3120) is 3102 MeV as 2S( 3/2+) state. Higher S state doublets are also predicted which will be useful for the identification of future experimental data.

Abstract
Herein we report the thermodynamic and transport properties of a polymer-DES solution. The density, apparent viscosity, electrical conductivity, and interfacial tension for the mixtures of poly (ethylene glycol) (PEG)/zinc chloride (ZnCl2)/ethylene glycol (EG) with various compositions were determined experimentally in the temperature range of 303.15 to 343.15 K. The variations of density, apparent viscosity, electrical conductivity, and interfacial tension with the temperature, PEG concentration, molar ratio of ZnCl2 to EG, and PEG molecular weight were analyzed and interpreted with the variations of H-bond, molecular thermal motion, polymer chain “end” effect, and polymer chain entanglement. The results showed that the hydrogen bond effect displayed enhancement with molar ratio of ZnCl2/EG and weakening with temperature, PEG concentration and molecular weight. The polymer chain “end” effect was enhanced with PEG concentration and weakened with PEG molecular weight. The effect of polymer chain entanglement was enhanced with PEG concentration and molecular weight. At low temperatures the Zn2+-EG H-bond was stronger than Zn2+-PEG while the situation became opposite at high temperatures. The correlations of density, apparent viscosity, and electrical conductivity with temperature and correlation of viscosity with density were conducted and the results showed that the activation energy of viscosity Eη showed increase while the activation energy of conductivity Eκ displayed decrease with the molar ratio of ZnCl2/EG and the closed-packed volumes of the PEG/ZnCl2/EG mixtures displayed increases with PEG concentration.

Published: April 2023

Abstract
Temozolomide (TMZ) has been used as a first-line therapy against low-grade gliomas (LGGs) combined with other chemotherapy drugs. However, there has been no reliable index predicting TMZ response of patients with LGGs. In this study, we aim to investigate the relationship between gene expressions and the prognosis of TMZ therapy in LGGs. We integrated transcriptome and clinical data of 171 LGGs from the Chinese Glioma Genome Atlas (CGGA). Consensus LASSO Cox regression was used to identify 14 key genes related to different clinical outcomes under TMZ chemotherapy. We constructed and evaluated a risk score based on the 14 genes. Patients with LGGs of lower risk scores (low-risk group) generally had better survival than those LGGs of higher risk scores (high-risk group), which is independent of clinicopathological factors. High-risk patients showed activation of innate and humoral-type immunity. The prognostic contribution of the risk score was validated in an independent validation cohort of 65 patients. Besides, combined with three independent predictors (grade, IDH1 mutation status, and chr1p19q co-deletion status), we further developed a nomogram to predict the benefit from TMZ treatment in LGGs. Our results indicate that transcriptome-based index can optimize the treatment strategy for patients with LGGs under TMZ therapy.

Abstract
The central and southern section of Tanlu fault zone is a section with frequent seismic activity and dense population distribution.Along the fault are infrastructure such as high-speed rail and the South-north Water Diversion project, as well as world heritage sites such as the Grand Canal, ancient city ruins and cultural landscapes. If a strong earthquake occurs in the future, it may cause great social impact and property losses.It is necessary to have a clear understanding of the current activity characteristics and potential seismic risk of fault zone to reduce the loss of earthquake disaster scientifically and reasonably.However, there are few data on its current activity characteristics through geodetic data.Based on GPS observation data from 1991 to 2020, the characteristics of fine slip distribution between present earthquakes in the mid-southern segment of the Tanlu fault zone are retrieved based on the fastest descent method. On this basis, the lock degree and slip rate deficit characteristics of this section are obtained；Finally, by comparing the surface strain results from 1991 to 2007 and 2013 to 2020, the differences of deformation characteristics between the two phases of the mid-southern segment of the Tanlu fault zone are analyzed.The results show that the interseismic sliding rate of the mid-southern segment of the Tanlu fault zone is 0 ~ 1 mm·-1，In the northern Tancheng-Sihong section, it showed right-handed thrust, and the sliding rate was between 0.2 ~ 1 mm·-1；The Sihong - Tongcheng section of the southern section is dextrorotally stretched, and the sliding rate is between 0 and 0.5mm.The degree of blockage in the mid-southern segment of the Tanlu fault zone is segmented along fault strike.In the north section, the locking depth of Changyi-Tancheng section was relatively high, with the deepest reaching 32 km,and the maximum compression-slide loss rate reaching -1mm·a-1；Tancheng-Wangji closure coefficient decreased significantly, with a concentrated distribution between 0.2 and 0.7. The Wangji-Jiashan section has a high degree of closure, small and medium earthquakes are not active, and it is the unruptured section, which is more prone to stress accumulation.
Goodwill, Earnings Predictability and Stock Mispricing: An Empirical Study on Agency Cost View
Authors: Jiang Allen 
Published: April 2023

Abstract
Existing literature reports that a company’s goodwill is not the higher the better. But is the value of goodwill affected by agency costs? Do investors understand the difference in the value of goodwill under different agency costs? These two questions are still unresolved. This paper studies the above questions from the influence of goodwill on the predictability of earnings and whether the stock price correctly reflects this influence, and uses the Mishkin model to test the effectiveness of the stock market in identifying the value of goodwill. This paper finds that higher book value of goodwill significantly reduces the predictability of earnings, especially when the agency costs of managers and major shareholders are high. But this fact is not understood by the market and leads to the mispricing. The mispricing will be corrected by the market from the second year, resulting in the reversal of stock returns. The results of this paper show that serious agency issues will lead to accounting information being distorted due to improper implementation of accounting standards, thereby affecting the efficiency of the stock market.

Abstract
Hypertensive diseases (HT) have become one of the leading causes of death among older people in developing countries, but data on HT-related deaths and HT-specific deaths in the whole population in the context of healthy ageing have not been well studied. We analysed the HT-related death and HT-specific death spectrum, crude mortality rate (CMR), age-standardized mortality rate by Segi’s world standard population (ASMRW), years of life lost (YLL) and age-specific proportion and then used the Joinpoint Regression Program to analyse the trends. We also studied the mortality rate increases by demographic age structure factors by the decomposition method. Of all 110,393 HT-related deaths, there were 5,757 HT-specific deaths in Pudong, Shanghai, from 2005–2020. The CMR, ASMRW, YLL and YLL rates of HT-related deaths (and HT-specific deaths) were 244.73/105 (12.76/105) person-years, 79.86/105 (4.22/105) person-years, 846,645.55 (43,912.98) years and 1,876.94/105 (97.35/105), respectively. The top 3 common causes of death among HT-related deaths (and HT-specific deaths) were cerebrovascular disease (heart disease), heart disease (renal failure) and diabetes mellitus (cerebrovascular disease). The HT-related and HT-specific CMR increased with age and year (all P < 0.05). The age-specific mortality rates decreased in age group 70–79 years, while in other groups, they increased or stabilized. The CMR caused by demographic age structure factors increased in the two groups (all P < 0.05). Our study provides new insights into the mortality trend of HT in a hyperaged society. As a common disease among older people, the burden of HT requires further study to meet the needs of healthy ageing.

Abstract
Two types of exploratory touch including active sliding and passive sliding are usually encountered in the daily life. The friction behavior of the human finger against the surface of objects is important in tactile perception. The neural mechanisms correlating to tribological behavior are not fully understood. This study investigated the tactile response of active and passive finger friction characterized with functional near-infrared spectroscopy (fNIRS). The friction test and fNIRS test were performed simultaneously using the tactile stimulus of polytetrafluoroethylene (PTFE) specimens. Results showed that the sliding modes did not obviously influence the friction property of skin. While three cortex regions were activated in the prefrontal cortex (PFC), showing a higher activation level of passive sliding. This revealed that the tribological performance was not a simple parameter to affect tactile perception, and the difference in cortical hemodynamic activity of active and passive touch was also recognised. The movement-related blood flow changes revealed the role of PFC in integrating tactile sensation although there was no estimation task on roughness perception.

Published: April 2023

Abstract
Background Evidence-based health and nutrition findings have a crucial role in improving the level of the problem and associated mortality reduction in children. With Borana experiencing a prolonged drought, our study sought to both update estimates and determinants of malnutrition in the zone and assess the impact of the drought on these estimates and determinants in order to inform drought response strategies.Methods A cross-sectional study was conducted among children under five years in Borena Zone from August 16 to September 03, 2022 using multistage cluster sampling technique. Data was collected by a structured questionnaire and anthropometrical measurements. The collected data was exported into STATA 15 for analysis. Multivariable logistic regression analysis was used to identify the factors associated with malnutrition.Results A total of 537 children aged from 6 months up to 59 months and their caregivers were included in the study. The prevalence of stunting, underweight and wasting was 40%, 33.5%, 27.6% respectively. The 12–24 months age group (AOR: 0.51, p = 0.021), unimproved water sources (AOR: 1.93, p = 0.003), and history of diarrhea in the two weeks prior to the survey (AOR: 1.66, p = 0.05) were independently associated with acute malnutrition. Moreover, living in urban areas (AOR: 1.68, p = 0.007), access to diversified food (AOR: 0.67, p = 0.046) and feeding frequency (AOR: 0.43, p = 0.044) were independent predictors of chronic malnutrition.Conclusion There was a higher prevalence of stunting, wasting, and underweight in Borena Zone than the national malnutrition prevalence. Community based nutrition programs need to be established to tackle the problem of malnutrition and exacerbate the impact of a prolonged drought in Borana. Interventions should be focused on improving household food security, use of improved water sources, and nutrition education to diversify child diet.

Abstract
Background Circular RNAs (circRNAs) are thought to play a crucial function in controlling gene expression, according to expanding findings. However, the importance of circRNAs in the regulation of acne inflammation is unclear.Methods Microarray analysis has been carried out to investigate circRNAs/miRNAs/mRNAs that express abnormally in acne. RNase R digestion assay is used for confirmation of the hsa_circ_0105040 characteristic. The functional roles of hsa_circ_0105040 on inflammatory response induced by Cutibacterium acnes (C. acnes) biofilm in human primary keratinocytes were revealed by Fluorescence in situ hybridization (FISH), Reverse transcription quantitative (PCR), Western blotting analysis, Immunoprecipitation, Luciferase reporter assay, Biotin-labeled miRNA pull-down assay, RNA immunoprecipitation (RIP).Results We first evaluate the human circRNA expression patterns in acne tissues and find that hsa_circ_0105040 expression is considerably reduced in acne tissues. Moreover, we discover that the majority of hsa_circ_0105040 is found to be localized in the cytoplasm of primary human keratinocytes. Hsa_circ_0105040 overexpression significantly enhances the production of proinflammatory factors (interleukin-8, interleukin-6, and tumor necrosis factor-α). Mechanistic research reveals that the microRNA miR-146a binds to hsa_circ_0105040, which then actively sponges miR-146a to prevent the level of IRAK1 and TRAF6.Conclusions These findings point to hsa_circ_0105040 as a critical circRNA that function as "microRNA sponges" for the controlled inflammatory response in the development of acne. Our findings may provide valuable insights into the progression of acne.

Abstract

The optimization of supercapacitive properties in carbon materials derived from cheap and sustainable wood scrap exhibits great application potential. Herein, in support of interfacial groups, polyaniline nanospheres were in-situ constructed in the internal pore structure of wood scraps, further the B and N element were imported by carbonized and hydrothermal. The doped B regulated the species of N-doping to improve the electrical conductivity of carbonized wood scraps, and endowed a certain pseudo-capacitance. Coupled with the fine double-layer capacitance from the hierarchical structures constructed by carbonized nanospheres and wood scrap channels, high specific capacitance of 406 F g-1 at 0.5 A g-1, high energy density (17.71 Wh kg-1 at 250 W kg-1) and cycle stability (93.04% capacitance retention after 10000 cycles) performed simultaneously. This study provided a new strategy to improve the supercapacitive performance of bio-carbon materials in terms of structure and conductance.

Authors: Gim Jeong-An 
Published: April 2023

Abstract

Background
Insights from public DNA methylation data derived from cancer or normal people can be obtained by machine learning. The goal is to determine the methylation pattern for predicting the prognosis for cancer patients and correcting lifestyles for normal people.
Methods
DNA methylation data were obtained from 446 healthy participants of 11 TCGA carcinomas, the Korean Genome Epidemiology Study (KoGES). For males and females, respectively, data from TCGA and KoGES were merged. To correct for the batch effect, R's ComBat function is used. Using the K-mean clustering (k = 3), the survival rates and chronic diseases were confirmed between the three groups of TCGA and KoGES.
Results
In a total of 82 female pancreatic cancer (TCGA-PAAD) patients and 220 normal participants, cluster 1 and 3 groups were compared. The survival rate in cluster 3 was significantly lower than in cluster 1. Among normal participants, the odds ratio according to the presence or absence of hypertension in two clusters was 2.18.
Conclusion
Based on the public DNA methylation and clinical data of normal participants and cancer patients, an analysis pipeline that integrates and clusters were provided. As a result of clustering, genes that explain survival and chronic disease were presented.

Abstract
China’s clean air actions since 2013 have led to dramatic changes in air pollutant emissions and surface air quality. Here, we investigated the trends and drivers of air pollutant emissions during the two phases of clean air actions (i.e., Phase I from 2013–2017 and Phase II from 2018–2020) in China. We estimated decreasing trends of nonmethane volatile organic compound (NMVOC) and NH3 emissions after 2017, representing the success of targeted policies for these pollutants during Phase II. However, regarding other pollutants, the emission reduction during Phase II were slowing down compared to those during Phase I. Although Phase II emphasized structural adjustment, end-of-pipe emission control measures remained the major drivers of emission reduction throughout the two phases. We thus recommend more active structural adjustment policies targeting the transition of the energy system in China.

Abstract
The rapid development of science and technology puts forward higher requirements for the quality and accuracy of high-performance impeller parts. In order to improve the machining accuracy of the inner surface and enhance the uniformity of the whole structure, In this paper, the large eddy simulation method is used to simulate and analyze the abrasive flow machining process of the high performance impeller with different machining parameters. Then the three processing parameters of inlet pressure, inlet speed and abrasive viscosity are simulated numerically. The results show that increasing the inlet pressure and abrasive viscosity can effectively improve the processing effect. Increasing the inlet speed will improve the processing intensity, but the overall processing uniformity will be reduced. The experiment result shows: The inlet pressure and particle size have a significant impact on the abrasive flow machining effect, followed by the number of machining times, and the surface roughness of the high-performance impeller after abrasive flow machining can reach 0.052µm, and the best technological parameters determined by the experimental research can realize the uniform polishing of the high performance impeller by abrasive flow machining technology.
