The Threshold Pion-Photoproduction of Nucleons In The Chiral Quark Model

Field: Physics and Astronomy (Physical Sciences)

In this paper, we show that the low energy theorem (LET) of the threshold pion-photoproduction can be fully recovered in the quark model. An essential result of this investigation is that the quark-pion operators are obtained from the effective chiral Lagrangian, and the low energy theorem does not require the constraints on the internal structures of the nucleon. The pseudoscalar quark-pion coupling generates an additional term at order $μ=m_π/M$ only in the isospin amplitude $A^{(-)}$. The role of the transitions between the nucleon and the resonance $P_{33}(1232)$ and P-wave baryons are also discussed, we find that the leading contributions to the isospin amplitudes at $O(μ^2)$ are from the transition between the P-wave baryons and the nucleon and the charge radius of the nucleon. The leading contribution from the P-wave baryons only affects the neutral pion production, and improve the agreement with data significantly. The transition between the resonance $P_{33}(1232)$ and the nucleon only gives an order $μ^3$ corrections to $A^{(-)}$.
An Averaging Technique for the Analysis of Rough Surface High Bearing Number Gas Flows

Field: Engineering (Physical Sciences)

Earlier analytical solutions by White (1980, 1983, 1992, 1993) included Couette effects, transverse diffusion, and mass storage in a model lubrication equation for narrow width wavy surface high bearing number gas films. The model lubrication equation did not include longitudinal diffusion effects due to the high bearing number restriction. Crone et al. (1991), however, reported numerical solutions of the full Reynolds equation for a gimbal mounted slider subject to wavy surface roughness. The first objective of this work is to reconcile the differences observed between the reported results of White and those of Crone et al. for moving and stationary roughness. The second objective is to describe how to best apply what appears to be a universal property of a high bearing number gas film subjected to a rough surface. Each solution of the model lubrication equation by White (1980, 1983, 1992, 1993) produced a product term based on local gas pressure and clearance (Z = Ph) that is independent of roughness details but which is dependent on the statistical properties of the roughness. In the present work, this characteristic is treated as a universal property of all high bearing number rough surface gas films. The product variable Z = Ph is introduced into the generalized full lubrication equation, and the resulting lubrication equation is ensemble averaged before a solution is attempted. This removes the short length and time scale effects due to the surface roughness. Solution of the ensemble averaged equation for Z(x, y, t) then follows by standard analytical or numerical methods. The unaveraged pressure is then given by P(x, y, t) = Z(x, y, t)/h(x, y, t) and the ensemble averaged or mean pressure at a point is computed from Pm(x, y, t) = Z(x, y, t)E(1/h(x, y, t)), where E(1/h) represents the ensemble average of 1/h. Using this technique, numerical solutions of the full generalized lubrication equation based on kinetic theory were obtained for a low flying gimbal mounted slider. Results indicate that the nominal flying height increases and the minimum flying height decreases as surface roughness increases.
Sacroiliac joint injection using the posterior superior iliac spines as landmarks: a preliminary study using cadavers

Field: Medicine (Health Sciences)

It is estimated that about 30% of cases of low back pain (LBP) are due to sacroiliac joint dysfunctions (SIJD). Accurate clinical diagnosis and treatment of LBP caused by SIJD is difficult without image guided techniques for needle placement into the sacroiliac joint cavity. Limitations in the availability of such image guided techniques in health institutions in developing countries are an obvious and major restriction, however the use of fundamental anatomic landmarks for surface marking of the sacroiliac joint for needle placement into the joint cavity is suggested as a useful substitute. Twelve adult cadavers (used for teaching) obtained from the Department of Anatomy, School of Medical Sciences, University of Science and Technology between 2006 and 2008 were studied. For each cadaver, the gluteal region was dissected to expose the bony posterior superior iliac spines (PSIS) and the posterior long sacroiliac ligaments. The proximal third of both posterior long sacroiliac ligaments were removed to expose the clefts between the two bones on both sides for the introduction of an IV cannula introducer needle 24G (Suruflon, Suru International PVT, Ltd, Mumbai) into the cleft between the two bones inferior to PSIS and advanced in a direction where the penetration was without resistance. A second needle was placed perpendicularly at the PSIS and radiographs of the posterioanterior view of the cadaveric pelvis were taken to confirm the placement of the needle in the sacroiliac joint, using Turdde 38 mobile X-ray machine. The needle position from the posterior superior iliac spine and its angle of inclination from the para-sagittal plane were measured. The data was analyzed using graph pad prism. The position of the needle ranged from 2 to 3.7 cm inferior to PSIS in all the cadavers with a mean of 2.52 cm (SE 0.09) for right and 2.59 cm (SE 0.20) for left. There was no significant difference between the right and the left needle positions of the joint (paired t-test, p>0.05). The angle of inclination of the needle ranged from 10o to 30o medial to the parasagittal plane with a mean of 24.58o (SE 2.2) and 25.12o (SE 1.8) for right and left respectively. These results show that an IV cannula introducer needle placed at 2-3 cm inferior to PSIS and directed at angle of 20-30o medial to the para-sagittal plane would get into the synovial part of the sacroiliac joint and confirms the intra-articular needle position within the sacroiliac joint using the PSIS as the anatomic landmark. These quantitative data present baseline values forfurther clinical investigation.
P10 Pregnancy outcomes in autoimmune hepatitis from a single tertiary centre

Field: Medicine (Health Sciences)

Background

Autoimmune hepatitis (AIH) affects women of reproductive age and data on pregnancy outcomes provide insight into managing this complex condition. Specifically, the effect of cirrhosis and immunosuppression use in AIH pregnancy would aid clinicians and women with pregnancy planning. This study aims to provide patient level data on pregnancy outcomes in AIH.

Method

A prospective database of self-reported pregnancies from women with liver disease was reviewed to identify AIH pregnancies. Medical records were used to gather retrospective data on demographics, preconception counselling, pregnancy outcomes, serological and biochemical markers.

Results

Between 1983 and 2022, there were 126 pregnancies from 74 women with AIH at King's College Hospital. Mean age at conception was 28 years and women with cirrhosis were significantly younger (p=0.48). There were 64 pregnancies from 41 women with cirrhosis at conception. Women who received pre-pregnancy counselling (n=32) were more likely to have a surveillance gastroscopy (p=0.03). The majority of patients were on immunosuppression (IS) at conception with 38 pregnancies on monotherapy, 50 on dual and 7 on triple IS. During gestation, there were no changes to IS in 90 pregnancies. 25 were not on IS at conception of which 2 were started on IS during pregnancy. The IS was reduced or stopped in 4 pregnancies. Complications in pregnancy were not increased in those with cirrhosis or on IS. There were 32 post-partum loss of biochemical remission (LOBR) of which 10 were not on IS. LOBR resulted in 1 fulminant liver failure requiring liver transplantation and 1 decompensation with ascites. A total of 99 live births (LB) were reported of which 15 were preterm birth (PTB) (32- 37 weeks gestation) and 2 very preterm (<32 gestation). The rate of miscarriages, stillbirths and PTB were not increased in those with cirrhosis or IS. Preconception albumin-bilirubin score (ALBI) and AST to platelet ratio index (APRI) was predictive of LB with area under receiver operator curve of 0.7547 (p=0.0011) and 0.700 (p=0.0123) respectively. ALBI cut-off of -2.870 has sensitivity of 78.95% and specificity of 67.31% for predicting LB whereas APRI cut-off of 0.305 has sensitivity of 72.22% and specificity of 56%.

Conclusion

Women with AIH including those with cirrhosis can expect favourable pregnancy outcomes. Women with preconception counselling were more likely to receive surveillance endoscopy. The continued use of immunosuppression did not increase adverse pregnancy outcomes and may reduce post-partum LOBR. The ALBI and APRI scores may be useful as prognostic tools.
Akt-Dependent Anabolic Activity of Natural and Synthetic Brassinosteroids in Rat Skeletal Muscle Cells

Field: Pharmacology, Toxicology and Pharmaceutics (Life Sciences)

Brassinosteroids are plant-derived polyhydroxylated derivatives of 5α-cholestane, structurally similar to cholesterol-derived animal steroid hormones and insect ecdysteroids. In this study, we synthesized a set of brassinosteroid analogues of a natural brassinosteroid (22S,23S)-homobrassinolide (HB, 1), including (22S,23S)-homocastasterone (2), (22S,23S)-3α-fluoro-homobrasinolide (3), (22S,23S)-3α-fluoro-homocastasterone (4), (22S,23S)-7-aza-homobrassinolide (5), and (22S,23S)-6-aza-homobrassinolide (6) and studied their anabolic efficacy in the L6 rat skeletal muscle cells in comparison to other synthetic and naturally occurring brassinosteroids (22R,23R)-homobrassinolide (7), (22S,23S)-epibrassinolide (8), and (22R,23R)-epibrassinolide (9). Presence of the 6-keto group in the B ring and stereochemistry of 22α,23α-vicinal hydroxyl groups in the side chain were critical for the anabolic activity, possibly due to higher cytotoxicity of the 22β,23β-hydroxylated brassinosteroids. All anabolic brassinosteroids tested in this study selectively activated PI3K/Akt signaling pathway as evident by increased Akt phosphorylation in vitro. Plant brassinosteroids and their synthetic derivatives may offer a novel therapeutic strategy for promoting growth, repair, and maintenance of skeletal muscles.
Site-Specific Covalent Labeling of RNA by Enzymatic Transglycosylation

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

We demonstrate the site-specific incorporation of nucleobase derivatives bearing fluorophores or affinity labels into a short RNA stem loop recognition motif by exchange of a guanine residue. The RNA-TAG (transglycosylation at guanosine) is carried out by a bacterial (E. coli) tRNA guanine transglycosylase (TGT), whose natural substrate is the nitrogenous base PreQ1. Remarkably, we have successfully incorporated large functional groups including biotin, BODIPY, thiazole orange, and Cy7 through a polyethylene glycol linker attached to the exocyclic amine of PreQ1. Larger RNAs, such as mRNA transcripts, can be site-specifically labeled if they possess the 17-nucleotide hairpin recognition motif. The RNA-TAG methodology could facilitate the detection and manipulation of RNA molecules by enabling the direct incorporation of functional artificial nucleobases using a simple hairpin recognition element.
Activity of the local self-government aimed at improvement of sanitary and hygienic situation in Vladivostok and Primorskaya Oblast in the conditions of modernization of the early XX century

Field: Social Sciences (Social Sciences)

The subject of this research is the activity of central and, specifically, local authorities aimed at ensuring conditions for public health and well-being in Vladivostok and Primorskaya Oblast in the early XX century. The goal is to determine the key problems pertaining to provision of urban amenities to the city and region, and the measures taken by the authorities to resolve them. Research methodology is based on the analysis of archival documents and a combination of special historical methods, such as problematic-chronological, comparative-historical, and classification. The author also used the materials from Primorsky State Archive, including cases of Vladivostok City Administration, reports of Vladivostok State Duma, and cases of the Military Governor of Primorskaya Oblast. In the conditions of modernization of the early XX century, including Stolypin's resettlement policy, the unpreparedness of suburbs of the Far East to mass population by foreign and Russian citizens became evident due to the absence of basic conditions of urban civilization. The conclusion is made that local authorities, relying on support of the central administration, undertook measures for ensuring favorable living conditions in the region. Leaning on examination of the previously unstudied archival documents, the author concludes on ineffectiveness of measures undertaken by the local authorities. The acquired results of can be applied in the current activity of local authorities, as well as in teaching historical disciplines universities, including such discipline as the History of the Primorsky Krai (in the department of Humanities at Pacific State Medical University). The experience accumulated demonstrates the effective solution for multiple issues.
Characterization of the roles of the Escherichia coli SeqA protein in vivo and in vitro by studying two different mutant SeqA proteins

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

The Escherichia coli SeqA protein, a negative regulator of chromosomal DNA replication, prevents the overinitiation of replication within one cell cycle by binding to hemimethylated GATC sequences in the replication origin, oriC. This process is termed sequestration. Lack of SeqA causes asynchronous initiation because of overinitiation. Binding of SeqA to hemimethylated GATC sequences may also be involved in segregating replicated chromosomes for cell division. SeqA has been found to affect DNA topology in vitro and this indicates that it might have a role in organizing DNA. In vivo, SeqA foci are formed that consist of SeqA proteins cooperatively bound to the newly formed hemimethylated DNA right behind the replication forks. Structural analysis has revealed that the SeqA protein consists of a DNA binding C terminal domain and an N terminal domain with self- association activity.\n\nIn order to understand more about the roles of SeqA protein in DNA replication and chromosome organization, two different sequestration deficient mutants, seqA3 and seqA4, with mutations in the C terminal and N terminal domain, respectively, were studied.\n\nThe two mutants were studied in vivo by flow cytometry and immunostaining followed by fluorescence microscopy. Both mutants were found to have an asynchronous phenotype and none of them were able to form discrete fluorescent foci.\n\nThe SeqA4 protein was purified as a His- tagged protein for in vitro studies. Gel filtration analysis showed that the molecular weight of the SeqA4 mutant protein was close to a tetramer, and that it lacked the wild type property of forming higher order structures with increasing concentration. This indicates that the N terminal domain is necessary for formation of higher order structures. Gel retardation assays showed that the mutant bound hemimethylated oriC as efficiently as wild type SeqA, but with a less cooperative binding pattern than wild type protein. The binding specificity for hemimethylated GATC sites was thus retained in the SeqA4 mutant protein. It was also able to bind to fully methylated oriC, but to a lesser degree and at a much higher concentration of protein compared to wild type SeqA. Supercoiling assays showed that wild type SeqA and the SeqA4 mutant protein affect plasmid topology differently. The SeqA4 mutant protein was capable of restraining fewer negative supercoils in a supercoiled plasmid than wild type SeqA. It was capable of introducing supercoils into a relaxed plasmid at the same level as wild type SeqA.\n\nThese results show that SeqA binding specificity and higher order oligomerization must both be intact for the formation of "DNA organizing" foci as well as for prevention or re- initiation.

The Usability-Error Ontology

Field: Health Professions (Health Sciences)

Clinical Systems have become standard partners with clinicians in the care of patients. As these systems become integral parts of the clinical workflow, they have the potential to help improve patient outcomes, however they have also in some cases have led to adverse events and has resulted in patients coming to harm. Often the root cause analysis of these adverse events can be traced back to Usability Errors in the Health Information Technology (HIT) or its interaction with users. Interoperability of the documentation of HIT related Usability Errors in a consistent fashion can improve our ability to do systematic reviews and meta-analyses. In an effort to support improved and more interoperable data capture regarding Usability Errors, we have created the Usability Error Ontology (UEO) as a classification method for representing knowledge regarding Usability Errors. We expect the UEO will grow over time to support an increasing number of HIT system types. In this manuscript, we present this Ontology of Usability Error Types and specifically address Computerized Physician Order Entry (CPOE), Electronic Health Records (EHR) and Revenue Cycle HIT systems.
Percentile pension cost methods with random retirement age

Field: Decision Sciences (Social Sciences)

A new family of methods for pension valuation is studied; Ramsay (1993) who originally proposed them called them percentile cost methods. These are compared to traditional cost methods and their differences are discussed. A numerical illustration is presented. In addition, this thesis models the retirement age as a random variable. The traditional and percentile cost methods are redefined under this more general random context.
Rapid Star Tracking Algorithm for Star Sensor

Field: Computer Science (Physical Sciences)

A rapid star tracking algorithm is proposed. In order to speed up the tracking, three techniques includng parallel star centroiding, sorting, and star catalogue partition are designed for three time-consuming portions in tracking algorithms. The parallel star centroiding is implemented with Field Programmable Gate Array (FPGA) which avoid image storage and transmission. Update rate of star sensor is improved. Sorting star coordinates in star image plane, and then matching, which avoid matching between stars with a long distance in image plane. Star catalogue partition divides the celestial sphere into many small partitions. In star mapping, guide stars are searched in the partitions near the direction of star sensor's boresight is not in the whole celestial sphere and therefore reduced the total number of searched guide stars. The software and hardware performance of tracking algorithms are simulated. Tracking robustness and the tracking speed comparison are tested in the software simulation. In hardware tests, the tracking time in every step is obtained.

Legal Construction of International Business Contracts as an Instrument for Strengthening Banana Cracker Exports and Ogan Banana Supply Chain Management in Lumajang Regency

Field: Social Sciences (Social Sciences)

Today's entrepreneurs prioritize international trade as an important goal in business development, which leads to the formation of international business contracts, but not all entrepreneurs understand the various regulations related to international business contracts, dispute resolution in the event of a dispute, and legal certainty in the event of force majeure. In addition, this study also wants to analyze the provisions for the use of Indonesian in agreements based on Law of the Republic of Indonesia Number 24 of 2009 concerning the Flag, Language, and National Emblem, as well as the National Anthem, with an analytical knife using the principle of freedom of contact. This research related to international business contracts was inspired by the desires of home industry entrepreneurs in Nogosari Village, Rowokangkung District, Lumajang Regency, who produce "banana crackers" and want to spread their wings into the world of international trade. In addition to understanding the various rules of international business contracts, banana crackers entrepreneurs also face the problem of difficulty in obtaining organic banana raw materials. Fruits have a high water content so they are easily damaged and have a short shelf life. Bananas are a type of fruit that is easily damaged, so there must be a solution, namely producing banana products, one of which is banana crackers and analyzing the management of the Supply Chain....

The Recently-Described Ant-Like Leaf Beetle Elonus gruberi (Coleoptera: Aderidae) in Michigan

Field: Agricultural and Biological Sciences (Life Sciences)

The ant-like leaf beetle Elonus gruberi Gompel, 2017 (Coleoptera: Aderidae) is reported for the first time in Michigan. This new state record, initially based on two recent collections by the author and then supplemented with additional material in a Michigan entomological collection, highlights how the constituents of faunal lists can require re-appraisal after taxonomic revision, particularly where splitting of species has occurred. The composition of Elonus Casey, 1895 in Michigan as well as characters for identifying E. gruberi also are discussed.
