Slip rate and slip magnitudes of past earthquakes along the Bogd left‐lateral strike‐slip fault (Mongolia)

We carried out morphotectonic studies along the left-lateral strike-slip Bogd Fault, the principal structure involved in the Gobi-Altay earthquake of 1957 December 4 (published magnitudes range from 7.8 to 8.3). The Bogd Fault is 260 km long and can be subdivided into five main geometric segments, based on variation in strike direction. West to East these segments are, respectively: the West Ih Bogd (WIB), The North Ih Bogd (NIB), the West Ih Bogd (WIB), the West Baga Bogd (WBB) and the East Baga Bogd (EBB) segments. Morphological analysis of offset streams, ridges and alluvial fans-particularly well preserved in the arid environment of the Gobi region-allows evaluation of late Quaternary slip rates along the different faults segments. In this paper, we measure slip rates over the past 200 ka at four sites distributed across the three western segments of the Bogd Fault. Our results show that the left-lateral slip rate is similar to 1 mm yr(-1) along the WIB and EIB segments and similar to 0.5 mm yr(-1) along the NIB segment. These variations are consistent with the restraining bend geometry of the Bogd Fault. ;Our study also provides additional estimates of the horizontal offset associated with the 1957 earthquake along the western part of the Bogd rupture, complementing previously published studies. We show that the mean horizontal offset associated with the 1957 earthquake decreases progressively from 5.2 m in the west to 2.0 m in the east, reflecting the progressive change of kinematic style from pure left-lateral strike-slip faulting to left-lateral-reverse faulting. Along the three western segments, we measure cumulative displacements that are multiples of the 1957 coseismic offset, which may be consistent with a characteristic slip. Moreover, using these data, we re-estimate the moment magnitude of the Gobi-Altay earthquake at M-w 7.78-7.95. ;Combining our slip rate estimates and the slip distribution per event we also determined a mean recurrence interval of similar to 2500-5200 yr for past earthquakes along the different segments of the western Bogd Fault. This suggests that the three western segments of the Bogd Fault and the Gurvan Bulag thrust fault (a reverse fault bounding the southern side of the Ih Bogd range that ruptured during the 1957 earthquake) have similar average recurrence times, and therefore may have ruptured together in previous earthquakes as they did in 1957. These results suggest that the western part of the Bogd Fault system, including the Gurvan Bulag thrust fault, usually behaves in a 'characteristic earthquake' mode.
Characterizations of Riemannian space forms, Einstein spaces and conformally flat spaces

In a recent paper the first author introduced two sequences of Riemannian invariants on a Riemannian manifold M, denoted respectively by 6(nl,. ,nk) and 5(ni,. ,nk), which trivially satisfy 6(ni,. ,nk) > 6(n,. , nk). In this article, we completely determine the Riemannian manifolds satisfying the condition 6(nfl,. , nk) = S(nl,. ,nk). By applying the notions of these 6-invariants, we establish new characterizations of Einstein and conformally flat spaces; thus generalizing two well-known results of Singer-Thorpe and of Kulkarni.
Asset Prices and Business Cycles with Liquidity Shocks

We develop a production based asset pricing model with financially constrained firms to explain the observed high equity premium and low risk-free rate volatility. Investment opportunities are scarce and firms face productivity and liquidity shocks. A negative liquidity shock forces firms to liquidate a fraction of their assets. We calibrate the model to U.S. data and find that it generates an equity premium and a level and volatility of risk-free rate comparable to those observed in the data. The model also fits key aspects of the behavior of aggregate quantities, in particular, the volatility of aggregate consumption and investment. JEL Codes: E20, E32, G12
Testing Efficiency of the London Metal Exchange: New Evidence

This paper explores the market efficiency of the six base metals traded on the LME (London Metal Exchange) using daily data from January 2000 to June 2016. The hypothesis that futures prices 3M (3-month) are unbiased predictors of spot prices (cash) in the LME is rejected based on the false premise that the financialization of commodities has been growing. For the robustness check, monthly data is analyzed using ordinary least squares (OLS) and GARCH (1,1) models. We reject the null hypothesis for all metals except for zinc.
Potential lineage transmission within the active microbiota of the eggs and the nauplii of the shrimp Litopenaeus stylirostris: possible influence of the rearing water and more

Background Microbial communities associated with animals are known to be key elements in the development of their hosts. In marine environments, these communities are largely under the influence of the surrounding water. In aquaculture, understanding the interactions existing between the microbiotas of farmed species and their rearing environment could help establish precise bacterial management. Method In light of these facts, we studied the active microbial communities associated with the eggs and the nauplii of the Pacific blue shrimp (Litopenaeus stylirostris) and their rearing water. All samples were collected in September 2018, November 2018 and February 2019. After RNA extractions, two distinct Illumina HiSeq sequencings were performed. Due to different sequencing depths and in order to compare samples, data were normalized using the Count Per Million method. Results We found a core microbiota made of taxa related to Aestuariibacter, Alteromonas, Vibrio, SAR11, HIMB11, AEGEAN 169 marine group and Candidatus Endobugula associated with all the samples indicating that these bacterial communities could be transferred from the water to the animals. We also highlighted specific bacterial taxa in the eggs and the nauplii affiliated to Pseudomonas, Corynebacterium, Acinetobacter, Labrenzia, Rothia, Thalassolituus, Marinobacter, Aureispira, Oleiphilus, Profundimonas and Marinobacterium genera suggesting a possible prokaryotic vertical transmission from the breeders to their offspring. This study is the first to focus on the active microbiota associated with early developmental stages of a farmed shrimp species and could serve as a basis to comprehend the microbial interactions involved throughout the whole rearing process.
Effect of DA-9701 on the Gastrointestinal Motility in the Streptozotocin-Induced Diabetic Mice

Background: Compared to the general population, diabetic patients experience more frequent episodes of gastrointestinal (GI) motility dysfunction, owing to the disruption of functional innervations. DA-9701 is a new prokinetic agent formulated from the extracts of Pharbitidis semen and Corydalis tuber. Aim: To investigate the effect of DA-9701 on GI motility in an animal model of streptozotocin (STZ)-induced diabetes. Methods: Diabetes was induced in mice by intraperitoneal injection of STZ (40 mg/kg of body weight in 0.1 M citrate buffer) for 3 days. Diabetic mice were divided into four groups and administered DA-9701 in different doses (1, 3, and 10 mg/kg) or placebo for 2 weeks. Intestinal transit was assessed using charcoal meal movement. GI isometric contraction was measured by applying an isometric force transducer on a circular muscle strip of the antrum, ileum, and proximal colon of sacrificed mice. Gastric emptying rate was evaluated by measuring the dye percentage remaining in the stomach relative to the total dye amount recovered in a standardization group of mice. Results: Body weight and antral and small intestinal motility were less in diabetic mice than in control mice, and colonic motility was similar in both. DA-9701 showed a dose-dependent increase in the amplitude of spontaneous phasic contractions in the antrum, ileum, and colon in diabetic mice without influencing body weight or blood glucose levels. The degree of improvement was comparable between diabetic and control mice. Intestinal transit was significantly more delayed in diabetic mice than in controls (43 ± 7% vs. 67 ± 8%, p < 0.05); however, DA-9701 restored the delayed intestinal transit more effectively compared to placebo (75% vs. 50%). The gastric emptying rate was significantly more delayed in diabetic mice than in controls (43 ± 10% vs. 62 ± 12%, p < 0.05), and was improved by DA-9701 in a dose-dependent manner (50%, 55%, and 60% in mice treated with 1, 3, and 10 mg/kg of DA-9701, respectively, vs. 43% in placebo-treated and 60% in control mice). Conclusions: DA-9701 improved GI contractility without affecting blood sugar and body weight in diabetic mice. DA-9701 could improve the decreased GI motility and clinical symptoms in progressive diabetic patients.
Demographic Aspects of Human Hydatidosis in Egypt

Background : Cystic echinococcosis or hydatidosis is caused by the larval stage of the tapeworm Echinococcus granulosus . It is one of the most important parasitic zoonoses. Objective: The aim of the work was to determine the prevalence of the disease in humans and its clinical presentation, also targeted to identify risk factors predisposing infections. Subjects and Methods: Thirty-one cystic echinococcosis cases were collected to determine the presence of hydatid cysts in human. Confirmation of hydatid cyst infection was done by radiological assessment and direct parasitological detection of hydatid cyst through PAIR technique or pathological confirmation of surgical removal cyst . A questionnaire survey to identify risk factors of transmission was also carried out . Results: The highest percent of infection with hydatid cyst was in age group 21-30 years (29.04%), followed by age group 31-40 years and 41-50 years that attained (25.81%) for each. Females attained the higher percent of infection (58.06%) in comparison to males (41.94 %). The highest percent of cystic echinococcosis was recorded for farmers (32.26 %) followed by housewives (29.03%). 67.75 % of cystic echinococcosis was for rural resident and (32.25%) was for urban resident. It could be concluded that hydatid disease is still an endemic problem and is a course of challenge to all the medical practitioners. The study has established that hydatidosis is prevalent in humans in Egypt and that the risk factors for its transmission exist.
Modifying two-body relaxation in N-body systems by gas accretion

We consider the effects that accretion from the interstellar medium onto the particles of an N-body system has on the rate of two-body relaxation. To this end, we derive an accretion-modified relaxation time by adapting Spitzer's two-component model to include the damping effects of accretion. We consider several different mass-dependencies and efficiency factors for the accretion rate, as well as different mass ratios for the two components of the model. The net effect of accretion is to accelerate mass segregation by increasing the average mass $\bar{m}$, since the relaxation time is inversely proportional to $\bar{m}$. Under the assumption that the accretion rate increases with the accretor mass, there are two additional effects that accelerate mass segregation. First, accretion acts to increase the range of any initial mass spectrum, quickly driving the heaviest members to even higher masses. Second, accretion acts to reduce the velocities of the accretors due to conservation of momentum, and it is the heaviest members that are affected the most. Using our two-component model, we quantify these effects as a function of the accretion rate, the total cluster mass, and the component masses. We conclude by discussing the implications of our results for the dynamical evolution of primordial globular clusters, primarily in the context of black holes formed from the most massive stellar progenitors.
Identification of SNP rs1799854 ABCC8 gene and blood glucose levels in patients with type 2 diabetes mellitus at Moewardi hospital Surakarta Solo

Type 2 diabetes mellitus (T2DM) is a complex metabolic disease characterized by high blood glucose levels due to impaired insulin secretion or insulin resistance. Polymorphisms in the ABCC8 gene rs1799854 are widely found to have an association with T2DM, where the ABCC8 gene encodes the SUR1 protein from the K-ATP channel that plays a role in insulin secretion in cells β pancreas. Mutations in the ABCC8 gene can cause potassium channels and insulin secretions problems that possibly decrease the effectiveness of the drug. Polymorphisms in some populations have been reported, but similar research on Solo's population has never been conducted. The purpose of this study is to identify the genotype of the ABCC8 gene in rs1799854 and the therapeutic outcome of blood glucose levels in T2DM patients. This research is cross-sectional research conducted prospectively at Moewardi Hospital Surakarta, Solo. Blood samples were collected from 10 T2DM patients who received sulfonylurea monotherapy taken through veins for genotype examination by DNA isolation, PCR amplification, and sequencing. Parameters of fasting blood glucose (FBG), 2-hour postprandial blood glucose, and HbA1c are measured as therapeutic outcomes . We found the dominant results in a mutant homozygote (TT) 40%; while wild type (CC); and a mutant heterozygote (CT) was 30%. Single Nucleotide Polymorphisms (SNP) of ABCC8 gene rs1799854, found in T2DM patients at Moewardi Hospital Surakarta, Solo, who received sulfonylurea therapy.

Flaw Tolerance in Lap Shear Brazed Joints — Part 1 Investigation brings a better understanding of the failure mechanism in brazed joints containing defects

Furnace brazing is a joining process used in the aerospace and other industries to produce strong permanent and hermetic structural joints. As in any joining process, brazed joints have various imperfections and defects. At the present time, our understanding of the influence of the internal defects on the strength of the brazed joints is not adequate. The goal of this three-part investigation is to better understand the properties and failure mechanisms of the brazed joints contain- ing defects. This study focuses on the be- havior of brazed lap shear joints because of their importance in manufacturing aerospace structures. In Part 1, an average shear strength capability and failure modes of the single lap joints are explored. Stainless steel specimens brazed with pure silver are tested in accordance with the AWS C3.2 standard. Comparison of the failure loads and the ultimate shear strength with the finite element analysis (FEA) of the same specimens as a func- tion of the overlap widths shows excellent correlation between the experimental and calculated values for the defect-free lap joints. A damage zone criterion is shown to work quite well in understanding the failure of the braze joints. In Part 2, the findings of Part 1 will be verified on the larger test specimens. Also, various flaws will be introduced in the test specimens to simulate incomplete braze coverage in the lap joints. Mechanical testing and FEA will be performed on these joints to verify that behavior of the flawed ductile lap joints is similar to joints with a reduced braze area. Finally, in Part 3, the results obtained in Parts 1 and 2 will be applied to the actual brazed structure to evaluate the load-carrying capability of a structural lap joint containing discontinuities. In addi- tion, a simplified engineering procedure will be offered for the laboratory testing of the lap shear specimens.
Synthesis, Biological Evaluation and Docking Studies of Chalcone and Flavone Analogs as Antioxidants and Acetylcholinesterase Inhibitors

Several oxidative processes are related to a wide range of human chronic and degenerative diseases, like Alzheimer’s disease, which also has been related to cholinergic processes. Therefore, search for new or improved antioxidant molecules with acetylcholinesterase activity is essential to offer alternative chemotherapeutic agents to support current drug therapies. A series of chalcone (2a–2k) and flavone (3a–3k) analogs were synthesized, characterized, and evaluated as acetylcholinesterase (AChE) inhibitors, and antioxidant agents using 1,1-diphenyl-2-picrylhydrazyl (DPPH•), 2-2′-azino-bis-(3-ethylbenzothiazoline-6-sulfonate) (ABTS•), and β-carotene/linoleic acid bleaching assay. Compounds more active were 3j and 2k in DPPH with EC50 of 1 × 10−8 and 5.4 × 10−3 μg/mL, respectively; 2g and 3i in ABTS (1.14 × 10−2 and 1.9 × 10−3 μg/mL); 2e, 2f, 3f, 2j, and 3j exceeded the α-tocopherol control in the β-carotene assay (98–99% of antioxidant activity). At acetylcholinesterase inhibition assay, flavones were more active than chalcones; the best results were compounds 2d and 3d (IC50 21.5 and 26.8 µg/mL, respectively), suggesting that the presence of the nitro group enhances the inhibitory activity. The docking of these two structures were made to understand their interactions with the AChE receptor. Although further in vivo testing must be performed, our results represent an important step towards the identification of improved antioxidants and acetylcholinesterase inhibitors.
Julia and Mandelbrot Sets for Dynamics over the Hyperbolic Numbers

Julia and Mandelbrot sets, which characterize bounded orbits in dynamical systems over the complex numbers, are classic examples of fractal sets. We investigate the analogs of these sets for dynamical systems over the hyperbolic numbers. Hyperbolic numbers, which have the form x + τ y for x , y ∈ R , and τ 2 = 1 but τ ≠ ± 1 , are the natural number system in which to encode geometric properties of the Minkowski space R 1 , 1 . We show that the hyperbolic analog of the Mandelbrot set parameterizes the connectedness of hyperbolic Julia sets. We give a wall-and-chamber decomposition of the hyperbolic plane in terms of these Julia sets.
Fatty Acid Amide Hydrolase Binding in Brain of Cannabis Users : Imaging With the Novel Radiotracer [ 11 C ] CURB

BACKGROUND: One of the major mechanisms for terminating the actions of the endocannabinoid anandamide is hydrolysis by fatty acid amide hydrolase (FAAH), and inhibitors of the enzyme were suggested as potential treatment for human cannabis dependence. However, the status of brain FAAH in cannabis use disorder is unknown. METHODS: Brain FAAH binding was measured with positron emission tomography and [C]CURB in 22 healthy control subjects and ten chronic cannabis users during early abstinence. The FAAH genetic polymorphism (rs324420) and blood, urine, and hair levels of cannabinoids and metabolites were determined. RESULTS: In cannabis users, FAAH binding was significantly lower by 14%–20% across the brain regions examined than in matched control subjects (overall Cohen’s d 5 0.96). Lower binding was negatively correlated with cannabinoid concentrations in blood and urine and was associated with higher trait impulsiveness. CONCLUSIONS: Lower FAAH binding levels in the brain may be a consequence of chronic and recent cannabis exposure and could contribute to cannabis withdrawal. This effect should be considered in the development of novel treatment strategies for cannabis use disorder that target FAAH and endocannabinoids. Further studies are needed to examine possible changes in FAAH binding during prolonged cannabis abstinence and whether lower FAAH binding predates drug use.
RELATIONSHIP BETWEEN C-REACTIVE PROTEIN TO ALBUMIN RATIO AND THE EXTENT OF CORONARY ARTERY DISEASE SEVERITY IN PATIENTS WITH NON ST ELEVATED MYOCARDIAL INFARCTION

Background: Coronary artery diseases (CAD) are as atherosclerotic heart disease, atherosclerotic cardiovascular diseases, coronary heart diseases (CHD), or ischemic heart disease (IHD). CAD is the largest contributor of cardiovascular diseases (CVDs), and mortality rate is due in prevalence to atherosclerosis, a chronic inflammatory condition of the arterial wall. Objective: To assess the relationship between C reactive protein /albumin ratio and the extent of coronary coronary disease assessed by the syntax score I in patients with non ST elevated myocardial infarction. Patients and methods: This was a prospective cohort study carried out at Cardiology Department of AlAzhar University, and Al-Agouza Cardiology Department, and enrolled 100 patients admitted with non STelevation myocardial infarction and underwent coronary intervention during the period from January 2019 to February 2020. Results: There was a non-statistically significant relation regarding gender and age. There was statistically significant relation regarding diabetes mellitus (DM) and dyslipidemia (cholesterol and LDL). There was also a statistically significant relation regarding syntax score, CRP and also CRP/Alb ratio. Conclusion: There was a correlation between CRP/ Albumin ratio and the severity of coronary artery disease assessed by syntax score I.
On prime ideals in rings of semialgebraic functions

It is proved that if p is a prime ideal in the ring S{M) of semialgebraic functions on a semialgebraic set M, the quotient field of S(M)/p is real closed. We also prove that in the case where M is locally closed, the rings S(M) and P(M)—polynomial functions on M—have the same Krull dimension. The proofs do not use the theory of real spectra.
Effect of different amounts of biochar on meadow soil characteristics and maize yields over three years

To evaluate the effect of biochar on soil characteristics and maize yields in meadow soil, a three-year field experiment was performed using different amounts of biochar (0, 10, 20, 40, and 80 t/ha). The soil pH decreased over time when biochar was applied to weakly basic soil. Single biochar applications increased the organic carbon, total nitrogen, available K, and cation exchange capacity for three continuous years, in proportion to the amount of biochar applied. However, as time progressed, the soil organic carbon, total nitrogen, available K, and cation exchange capacity began to decrease. The biochar stimulated the availability of soil phosphorus in the meadow soil and stably increased the available P content in the soil for three years. For maize, the biochar application decreased the occurrence of barren ear tips and increased the ear length, grain number per row, 100-kernel weight, and yield. When the single applications of biochar were greater than 40 t/ha, the soil characteristics showed continuous improvements and the maize yields stably increased for three years.
