Approximate analytical solution of fractional-order generalized integro-differential equations via fractional derivative of shifted Vieta-Lucas polynomial

In this paper, we extend fractional-order derivative for the shifted Vieta-Lucas polynomial to generalized-fractional integro-differential equations involving non-local boundary conditions using Galerkin method as transformation technique and obtained N - \delta + 1 system of linear algebraic equations with \lambda i, i = 0, . . . , N unknowns, together with \delta non-local boundary conditions, we obtained (N + 1)- linear equations. The accuracy and effectiveness of the scheme was tested on some selected problems from the literature. Judging from the table of results and figures, we observed that the approximate solution corresponding to the problem that has exact solution in polynomial form gives a closed form solution while problem with non-polynomial exact solution gives better accuracy compared to the existing results.

Migration and tectonic implications of Late Jurassic mafic magmatism in South China

The Jurassic magmatism in the southeastern South China Block has been interpreted as extension-related, yet its tectonic drivers remain unclear. Tectonic models vary between two end-members: (1) Palaeopacific subduction-related; and (2) intracontinental extension-related. This study presents new geochronological and geochemical data for the Late Jurassic mafic rocks in the southeastern South China Block that allow us to differentiate between these tectonic models. The Late Jurassic mafic rocks yielded crystallization ages of 162–157 Ma. Our new geochemical data, together with previously published data, can be divided into three groups: group A with variable ε Nd ( t ) (+0.1 to +3.4) and zircon ε Hf ( t ) (−4.1 to +15.9) values has slightly negative Nb–Ta anomalies; group B is characterized by negative Nb–Ta anomalies with varying ε Nd ( t ) (+1.4 to +1.5) and ε Hf ( t ) (–3.0 to +2.6) values; and group C displays significant Nb–Ta anomalies with high ε Nd ( t ) (+4.5 to +6.6) and ε Hf ( t ) (+6.4 to +14.4) values. The geochemical characteristics suggest that groups A and B are mainly the products of asthenosphere–lithosphere interactions and group C was derived from the asthenosphere. Our new data, together with geological observations, suggest that the Late Jurassic magmatism in the southeastern South China Block probably resulted from asthenospheric upwelling in an intracontinental extension setting due to the far-field effects of the subduction of the Palaeopacific Ocean.

Knowledge, Perception and Preparedness Related to COVID-19 among Adult Rural Population in Konso, Southern Ethiopia.

According to the world health organization, the COVID-19 outbreak has currently affected millions of people worldwide. Since the start of the pandemic in China, everything countries have thrown at the virus turned unsuccessful. As there is no established vaccine to halt the virus transmission, it might be very difficult for developing countries like Ethiopia even after vaccine development. Thus, focusing on improving knowledge, perception, and preparedness related to the virus might be very vital. A community-based cross-sectional survey was conducted using the questionnaire applied in most countries which is suitable to apply in the Konso zone in South Nations Nationalities Region (SNNPR) from April.2020 to July 2020. Data were collected, cleaned, coded, checked, and entered into Epi Info and then exported and analyzed in STATA 15. We fitted a binary logistic regression model. Categorical variables were presented using figure tables, and proportion and for continuous variables, mean and standard deviation were used. The results were also presented using Adjusted Odds Ratio (AOR) with 95% CI. From 636 respondents expected, 615(97%) were participated and possessed the knowledge of 39%, and 64% perception and preparedness each. Measurements related to the policy and interventions like restrictions to movement, self-isolation, wearing a face mask, & the need for more tests was not supported by most participants. The poor knowledge, perception, and preparedness were correlated with the unavailability of water and electricity, less education, and informal source of information which could be improved through area appropriate health education interventions.

Was sagt uns ein Gesetz?

Abstract What kind of rhetoric does a statute present? In the following essay, you will find, after the introduction (1.), the answer in studying interpretants (2.). When you look at written law, you find at least four different types: the academic Roman today antecedent (3.a), the modern blanket clause of the police (3.b), the constitutional clauses which date from the same time (3.c), and finally the last post-modern product as a type of rule which determines the legal form itself (3.d). With tables of measures, figures, and clauses of discretion, it attempts to suppress the disturbance of interpretants (4.).

PELATIHAN PENGGUNAAN TABLE OF FIGURES (TOF) DAN INSERT CAPTION UNTUK MEMBUAT DAFTAR TABEL DAN DAFTAR GAMBAR MAKALAH SECARA OTOMATIS DI SMK PAB 8 SAMPALI

The purpose of community service activities is to implement the Tri Dharma of Higher Education and provide learning how to use Table of Figures (TOF) and Insert Captions to create a list of tables and a list of pictures of papers automatically at SMK PAB 8 Sampali. A paper is a work that is written, has a scientific nature and contains a discussion on a particular topic. In a paper, a table of contents, a list of tables and a table of figures is one of the components that must be present. Generally, students often make lists of tables and lists of pictures manually. As a result, sometimes the results obtained are not neat and not in accordance with the rules of writing the correct picture list. Even though Microsoft Word has provided the Insert Table of Figures feature that makes it easy for users to create a list of images or a list of tables automatically. Through training for SMK PAB 8 Sampali students, it is hoped that they will be able to use Table of Figures (TOF) and Insert Captions to write papers correctly as a support in the teaching and learning process.

Spatial and temporal influence of Pacific subduction on South China: geochemical migration of Cretaceous mafic–intermediate rocks

The Cretaceous igneous rocks in the South China Block (SCB) were associated with the slab subduction and roll-back of the Pacific Plate. Thus, they provide excellent opportunities to examine the spatial–temporal geochemical migration of magmatism in the retreating subduction margins. The Cretaceous mafic–intermediate igneous rocks from the southeastern SCB were aged between 142 and 71 Ma, and can geochemically be subdivided into three groups: Group A (126–129 Ma and 83–93 Ma), Group B (126–142 Ma and 71–108 Ma) and Group C (116–142 Ma and 70–110 Ma). Group A and B were mainly distributed in the SCB interior and derived from asthenosphere and asthenosphere–lithosphere interaction sources, respectively. Group C occurred to the east of the Ganjiang Fault and originated from slab–lithosphere interaction. From the coastal provinces to the interior, these mafic–intermediate igneous rocks show increasing incompatible element ratios and Nd isotopic compositions, reflective of a westerly decreasing involvement of slab-derived components. They show two similar age-pulses at c . 125 Ma and c . 90 Ma as well as the Cretaceous A-type granites, indicating two episodes of subduction retreat of the Pacific slab during the Cretaceous. This spatial–temporal pattern of the Cretaceous mafic–intermediate igneous rocks suggests that the Cretaceous slab metasomatism of Pacific subduction retreat was limited to the east of the Ganjiang Fault.

Neuroprotective effects of Ghrelin on traumatic brain injury in mice

Objective To investigate the neuroprotective effect of Ghrelin on traumatic brain injury (TBI) in mice. Methods TBI model of C57BL / 6 mice was established by electronic cortical impact instrument (eCCI). According to the random figure table method, twenty-four mice were randomly divided into sham group(Sham group), TBI group and Ghrelin intervention group(Ghrelin group) with 8 mice in each group. The model of TBI was established in TBI group and Ghrelin group.The mice in Ghrelin group was injected intraperitoneally 0.5 g/kg before and 1 h after injury respectively. And the mice Sham group and TBI group were injected with the same amount of normal saline. The changes of cerebral blood perfusion (CBP) were monitored in real time by laser speckle contrast analysis(LSCI), the changes of neuroelectrophysiology were observed by monitoring motor evoked potential (MEP), and the status of neurological deficit was evaluated by modified neurological deficit score (mNSS). Results Compared with Sham group, the mice in TBI group had significantly lower cerebral blood perfusion(CBP) (t=-12.36, P<0.01), longer latency and lower amplitude of motor evoked potential (MEP) (t=5.03, -11.55, all P<0.01), and significantly higher mNSS scores (t=9.34, P<0.01). However, compared with the TBI group, the cerebral blood perfusion(CBP) of Ghrelin group increased significantly at 12 h after TBI((196.87±17.36) PU/mm2vs (123.62±8.04)PU/mm2, t=10.45, P<0.01), while the latency of MEP decreased((5.30±0.33)ms vs (6.80±0.97)ms, t=-5.01, P<0.01), the amplitude of MEP increased((2.21±0.16)mV vs (1.27±0.27)mV, t=9.65, P<0.01). And compared with the TBI group, the neurological deficit score of Ghrelin group decreased significantly at 24 h after TBI((4.9±1.2) vs (8.4±2.6), t=-3.87, P<0.01). Conclusion Ghrelin exhibits a significant neuroprotective role by increasing cerebral blood flow perfusion, reducing the degree of neurological deficit and promoting motor function recovery in TBI mice.

High Accuracy Battery Modeling : Fully 3D-Resolved Lithium-Ion Battery Mesostructure Including Carbon Binder Domains

In the literature, reported 3D-resolved models rely on oversimplifications, such as an implicit representation of the carbon-binder domains (CBD) through the use of effective parameters for porosity and tortuosity or by merging CBD with the Active Material (AM) as a single solid phase. This work’s novelty relies on the explicit representation of CBD, leading to a new level of accuracy in terms of electrochemical modeling. This achievement is made possible thanks to an in-house algorithm, called INfinite Number Of phases meshing through Voxelization (INNOV) [1] . INNOV can generate a volumetric mesh from data of different types due to its flexible input format. INNOV takes as input binary stack of images to reconstruct the 3D structure. Such an input can result from tomography imaging, from slicing a 3D object or from Coarse Grained Molecular Dynamics (CGMD) simulations [2] . For the latter a function has been developed to convert its output (coordinates of the centers and radii of the particles) into a binary stack of images. The segmentation method of Nielson and Franke [3] has been translated and optimized for MATLAB language and modified to suit the COMSOL Multiphysics meshing importation process. This algorithm is designed in the scope of the ARTISTIC Project [4] to import a multi-phase volumetric mesh of an electrode (from a CGMD simulation) into COMSOL Multiphysics to simulate the performances of the cell. The core of this work is to increase the current level of precision of the modeling of batteries by separating active and inactive materials. In doing so, one must not sacrifice the integrity of the mesostructure geometry. To ensure this, INNOV provides a number of observables, which can be compared to experimental numbers (e.g. arising from tomography characterizations). Once the integrity of the mesh is ensured, electrochemical simulations can be done to characterize the structure (Figure 1). Such characterizations can capture the role of CBD to further understand the limiting phenomena and predict the optimal LIB structure to achieve the optimization of the fabrication process. Simulations on NMC/Li half-cell have been carried out to demonstrate the versatility of this algorithm. In conclusion, INNOV offers a time-efficient tool to perform meshing without requiring substantial computational resources. Simulations can later be performed to characterize these meshes with the CBD explicitly considered. It is also a powerful tool to couple with tomography imaging. FIGURE TABLE Figure 1.

The clinical effects of acupuncture combined with Mingmu-Dihuang pill on dry eyes

Objective To evaluate the effect and safety of acupuncture combined with Mingmu-Dihuang pill in patients with dry eyes. Methods A total of 100 patients with dry eye were enrolled in line with the inclusion criteria and divided into experimental group and control group by random figure table. The experimental group was treated with acupuncture combined with Mingmu-Dihuang pill, and the control group was treated with artificial tears. After 2 months of treatment, the Schirmer test (schirmerI, SIT), tear film break up time (BUT), fluorescent staining (FL) and clinical symptom score were observed and compared, and the clinical efficacy and safety were evaluated. Results The total effective rate of the experimental group was 89.0% (89/100) and the control group was 67.0% (67/100), and the difference was significant (χ2=14.121, P<0.001). After treatment, the levels of BUT (7.89 ± 1.65 s vs. 5.01 ± 1.72 s, t=8.543), SIT (7.45 ± 1.68 mm vs. 5.01 ± 1.72 mm, t=5.991) in the experimental group were significantly higher than those of the control group, and the difference is significant (P<0.01). The FL score and dry eye score in the experimental group were significantly lower than those of the control group (t were 11.551, 12.342, P<0.01). Conclusions Acupuncture combined with Mingmu-Dihuang pill has better clinical effect and good safety for the treatment of dry eye patients.

Hydrocarbon charge assessment of frontier basins – a case study of the oceanic crust of the Moroccan Atlantic margin

A string of prominent structural anticlines is located in the deep offshore Atlantic Ocean c. 150 km west of Essaouira (Morocco), possibly forming large traps. However, the basement is inferred to comprise oceanic crust, which raises concerns for source-rock presence and sufficient subsurface temperatures for oil generation. The presented work showcases a hydrocarbon charge assessment approach adapted to the very sparse data context and the specific geodynamic settings of the Moroccan Atlantic margin. Regional 2D basin and petroleum systems modelling was performed to assess possible scenarios of hydrocarbon charge of the deep-water folds, its migration style and timing. Several possible oil and gas generation drivers have been identified for postulated Toarcian marine shale source rocks. These range from simple burial-driven heating to more unique scenarios involving early stage oceanic ridge heating and the effect of the Canary Island hotspot. In particular, the latter might have had a major impact on the oil and gas generation, the migration style and overall accumulated amounts.

The significance and managerial challenges of virtual teamworking

Abstract Living in a world where technology has evolved in an alarming pace, the working structures have become more diverse adapting to this trend, and giving birth to virtual teams, thanks to the ITC tools that have broken the physical boundaries, allowing coworkers to connect from all corners of the world and construct together. The aim of the article is to enrich the effectiveness of virtual teams but also acknowledge the difficulties they may run into throughout their project completions. Mixed methodology was chosen for the study case, having the Romanian Tourism Heritage Federation members as the sample of the survey. The quantitative method was used to quantify the data offered by the surveyed candidates and offer a deeper insight, by collecting data regarding certain aspects of the candidate such as: age, education and experience level, online “literacy”, size and role of the team member etc. and presented in a well-structured figure table. Whereas, the qualitative method concentrated on obtaining beneficial data regarding aspects as: cultural and technological barriers, trust and team commitment barriers along with social interaction ones, as well as leadership and team dynamics perspective. The findings of the research were gathered, interpreted and presented briefly, giving a comprehensive image of the “virtual team” nowadays, facing both fruitful and challenging traces in their working style.

Analysis of the effect of laparoscopy and hysteroscopy on ovarian function, immune function and quality of sexual life of patients with hysteromyoma at different ages.

This study aims to comparatively analyze the impact of laparoscopic myomectomy (LM) and transcervical resection of myoma (TCRM) on ovarian function, immune function and quality of sexual life of patients with hysteromyoma. Two hundred and forty patients with hysteromyoma admitted into the Second Affiliated Hospital of Zhengzhou University from June 2014 to June 2016 were divided into laparoscopic myomectomy group (LM group, n=120) and transcervical resection of myoma group (TCRM group, n=120) according to random figure table. The difference between the two surgical methods were compared among hysteromyoma patients of different age in the following aspects: perioperative indicators, ovarian function, immune function and quality of sexual life before treatment and after operation. 1) there was no significant difference in age structure between LM and TCRM group (P>0.05). 2) There were no significant differences in the amount of bleeding, operative time, analgesics usage rate between the groups (P>0.05), but the anal exhaust time, postoperative ambulation time, hospitalization time and hospitalization costs in TCRM group were significantly less than that in LM group, the difference was statistically significant (P<0.01). 3) Before treatment and in the 3rd, and 6th month after operation, there was no significant difference on follicle stimulating hormone (FSH), luteinizing hormone (LH) or estradiol (E2) level between the two groups (P>0.05); but in the 3rd month after operation, the level of E2 decreased remarkably, with FSH and LH level increased significantly compared with the 6th month after operation and before treatment (P<0.05). 4) Compared with the preoperative status, there was no significant decrease in humoral immunity (IgG, IgA, IgM) and cellular immune function (CD4+, CD8+) in TCRM group at the 3rd and 6th month after operation (P>0.05). While at the 3rd month after operation, the levels of CD4+, CD8+ were decreased significantly in comparison to those at the 6th month after operation (P<0.05), but the levels of IgG, IgA and IgM were not decreased significantly (P>0.05). 5) There was no significant difference in the quality of sexual life between the two groups before operation or at the 3rd and 6th month after operation (P>0.05). In recent years, endoscopic treatment has become the main treatment evolution of hysteromyoma, patients of all ages are paying attention to the preservation of the uterus. This study showed that TCRM is approaching through the natural cavity, which has the features of less damage to body, faster recovery and lower cost of hospitalization than LM. The two surgical methods have no obvious influence on ovarian function, immune function and quality of sexual life.

The Influence of Corrosion Attack on Grey Cast Iron Brittle-Fracture Behaviour and its Impact on the Material Life Cycle

The paper is concerned with brittle‑fracture behaviour of grey cast iron attacked by corrosion and its impact on the life cycle of a spare part made of grey cast iron. In a corrosion chamber, outdoor climatic conditions (temperature and relative air humidity) were simulated in which degradation processes, induced by material corrosion, degrading mechanical properties of a material and possibly leading to irreversible damage of a machine component, occur in the material of maintenance vehicles that are out of operation for the period of one year. The corrosion degradation of grey cast iron, which the spare parts constituting functional parts of an engine are made of grey cast iron, is described with regard to brittle‑fracture behaviour of the material. For the description of corrosion impact on grey cast iron, an instrumented impact test was employed. A corrosion degradation effect on grey cast iron was identified based on measured values of total energy, macro plastic deformation limit, initiation force of unstable crack propagation and force exerted on unstable crack arrest. In the first part of the experiment, a corrosion test of the material concerned was simulated in a condensation chamber; in the second part of the experiment, research results are provided for the measured quantities describing the material brittle‑fracture behaviour; this part is supplemented with a table of results and figures showing the changes in the values of the measured quantities in relation to test temperatures. In the discussion part, the influence of corrosion on the values of unstable crack initiation and arrest forces is interpreted. In the conclusion, an overview of the most significant research findings concerning the impact of corrosion on the life cycle of grey cast iron material is provided.

A Spectrogram‐Based Method ofRgDetection for Explosion Monitoring

Abstract The detection of the high‐frequency fundamental‐mode Rayleigh‐wave Rg is important for explosion monitoring efforts because it indicates a shallow source, which is most often man‐made. We developed an automated Rg detector that successfully identifies Rg using the spectrogram of the seismic signal to find peaks in the characteristic Rg frequency band. We tested the detector using a network of over 200 seismometers in Wyoming, which recorded dozens of nearby coal‐mining blasts and active‐source tamped borehole shots. The detector finds peaks in the summed spectrogram amplitudes from 0.4 to 0.8 Hz for mining blasts and from 0.8 to 1.5 Hz for borehole shots. We achieved successful Rg detection of mining blasts across the entire array for the largest blasts, though smaller blasts had less success at distant stations, due to low signal amplitude. Similarly, Rg detection from borehole shots was successful at distances Finally, we compared our method with an existing Rg detection method based on finding retrograde particle motion, typical of Rg , in signal coming from the known source–receiver back azimuth. In our application, the detector worked well for more distant stations but failed at stations within the same basin as the source, where Rg has prograde particle motion. The two detectors are fundamentally different; the new detector is easier to automate but depends on Rg having larger amplitude than the pre‐ Rg time window, whereas the existing detector triggers based on the particle motion and the direction of arrival, independent of the amplitude. The new method, perhaps in conjunction with the existing method, can offer increased monitoring capability and higher confidence when detecting Rg .

The Ediacaran–Cambrian transition in the Cantabrian Zone (northern Spain): sub-Cambrian weathering, K-metasomatism and provenance of detrital series

The Upper Ediacaran detrital succession in the Cantabrian Zone shows geochemical and mineralogical changes resulting from sub-Cambrian weathering during the Late Ediacaran worldwide sea-level fall. Relative to the unaltered rocks the altered ones show crosscutting rubefaction of varying thickness and remarkable increase in illite, K 2 O, Rb and Cs indicating K-metasomatism, and also depletion in MgO, CaO, Na 2 O, Be and Sr, but not in Zr, Nb, Y or Sc. The basal Cambrian siliciclastic rocks mostly consist of detritus derived from the Ediacaran materials, as demonstrated by the geochemical and Nd-isotope data ( ε Nd ( t ) ranges are −3.4 to −2.1 and −3.6 to −1.8, respectively). However, these geochemical features of the basal Cambrian change upwards to more evolved compositions with lower ε Nd ( t ) values (−4.9 to −5.8). This change coincides with the Ediacaran–Cambrian unconformity in the Central Iberian Zone, and the Ediacaran siliclastic rocks of this zone and their unaltered equivalents of the Cantabrian Zone share the same geochemical features. This geochemical homogeneity rules out a significant coeval juvenile contribution to the Upper Ediacaran series. Thus, the juvenile supply was from a geological setting different from that in which the Ediacaran series were finally deposited.

Search, Liquidity, and the Dynamics of House Prices and Construction: Corrigendum

In the course of our ongoing research, we have discovered two substantive errors in this article. These mistakes do not affect significantly either the qualitative nature of the results or any of the principal conclusions stated in the paper. They do, however, affect the specific quantitative results. One error affects the empirical findings presented primarily in Section I and the online Appendix. The other involves the calculation of sales of existing houses in artificial data generated by the model. This affects both the calibration (Section IV) and the equilibrium dynamics in Section V, principally with regard to the dynamics of sales. The article’s quantitative results are presented through tables of statistics and figures depicting impulse responses. Virtually all of the specific numerical values in these tables and figures are affected, most only trivially, but some significantly. In this corrigendum, we describe the two errors and present corrected values and new versions for the statistics and figures most affected (we number the tables and figures as in the original article and the revised online Appendix). Updated, correct programs have replaced those containing the mistakes on the AER’s website, and the revised online Appendix contains a complete set of corrected tables and figures.

Shear Waves from Isotropically Dominated Sources: Comparison of the 2013 Rudna, Poland, and 2007 Crandall Canyon, Utah, Mine Collapses

Comparison of observed and synthetic radiation patterns suggests that Love waves generated by the 2007 Crandall Canyon Mine collapse ( M w 4.1) are the result of shear waves generated by a relatively large compensated linear vector dipole component at the source, whereas the Love waves associated with a 2013 Rudna Mine collapse ( M w 4.2) are minimal except where amplified by a deep sedimentary basin. We examine the source of the 19 March 2013 Rudna Mine, Poland, collapse with a full moment tensor inversion method, using the complete waveforms of regional‐distance seismic data. The computed source is primarily composed of a dominant, and statistically significant, implosive component. The Rudna source is more similar to previous mine collapses than to double‐couple tectonic earthquakes. Although source mechanisms are similar, there are clear differences in Love‐wave amplitudes.

Indicators of mental health of pre-school children in Irkutsk amid the wide introduction of information technologies

Aim. To assess the mental activity of pre-school children amid the wide introduction of information technologies. Methods. 176 children aged from 5.5 to 6.5 years were observed at the institution of pre-school education of Irkutsk central district from 1998 to 2012. Two groups were formed: the first group included 101 child who attended childcare center in 1998, the second group - 76 children who attended childcare center in 2012. Age groups of pre-school children were formed according to their age (from 5 years 5 months 30 days of age to 6 years 5 months 30 days of age). The mental activity was assessed using the figure tables by V.Y. Anfilov assessing the number of made mistakes and number of lines run through. Every missed line was equal to one mistake made. The productivity coefficient Q was calculated as Q=c2/c+d, where с - the number of lines run through; d - the number of mistakes (mistakes were not standardized). Results. The parameters of productivity did not change significantly in 2012 compared to 1998. The number of lines run through at Anfilov’s test increased by 1.8 times (р 0.05) in children of the second group (examined in 2012), the number of mistakes made increased by 7.5 times (р 0.05). Among the girls of the second group, the number of lines run through increased by 1.6 times (р 0.05), the number of mistakes made increased by 6.3 times (р 0.05). The trend was clearer in boys, in whom the number of lines run through increased by 2.0 times (р 0.05), the number of mistakes made increased by 8.3 times (р 0.05). Conclusion. The speed of information processing has increased, and the quality of information processing has dropped in contemporary pre-school children. The overall productivity did not change.
