C-reactive protein/abumin ratio is a useful biomarker for predicting the mucosal healing in the Crohn disease

Abstract Ileocolonoscopy is currently recognized as the gold standard for evaluating mucosal healing in patients with Crohn disease (CD). However, the ideal noninvasive marker to assess mucosal healing instead of invasive ileocolonoscopy is not available. This study aimed to determine the correlations between the mucosal healing and serological optimizing markers in CD. This retrospective study consecutively included 62 CD patients with 137 hospitalizations between March 2014 and March 2020. On the basis of the Simple Endoscopic Score for Crohn's disease (SES-CD), the CD patients were divided into mucosal healing group (SES-CD ≤ 2) and nonmucosal healing group (SES-CD > 2). We collected the results of ileocolonoscopy examination and inflammatory markers and then serological optimizing markers, including C-reactive protein/albumin ratio (CRP/ALB), platelet/albumin ratio (PLT/ALB), neutrophil-lymphocyte ratio (NLR), and platelet-lymphocyte ratio (PLR) were calculated. The control group consisted of 50 healthy volunteers in the corresponding period. We found that CRP/ALB, PLT/ALB, NLR, and PLR were correlated with the mucosal healing of CD, and the correlation of CRP/ALB with the mucosal healing was the highest (r = -0.64). Receiver operating characteristic (ROC) analysis showed that the area under the curve (AUC) of CRP/ALB (0.87) was higher than NLR (0.69), PLR (0.72), and PLT/ALB (0.81). In the efficacy of assessing the mucosal healing in CD, the sensitivity of CRP/ALB, NLR, PLR, and PLT/ALB were 91.1%, 83.9%, 73.2%, and 73.2%, respectively, and the specificity was 76.5%, 46.9%, 64.2%, and 75.3%, respectively. CRP/ALB was the most appropriate marker to assess CD mucosal healing among the serological optimizing markers.
La0.8Sr0.2Ni0.4Fe0.6O3–Ce0.8Gd0.2O2–δ Nanocomposite as Mixed Ionic–Electronic Conducting Material for SOFC Cathode and Oxygen Permeable Membranes: Synthesis and Properties

Mixed ionic–electronic conducting nanocomposite La0.8Sr0. 2Ni0.4Fe0. 6O3 (LSNF)–Ce0.8Gd0. 2O2– δ (GDC) was prepared via ultrasonic dispersion of nanocrystalline powders of perovskite and fluorite oxides in water with addition of surfactant, followed by drying and sintering up to 1300°C. Analysis of the real structure of nanocomposite (studied by XRD and TEM with EDX) and its surface composition (studied by XPS) revealed moderate redistribution of elements between phases favoring their epitaxy. Results of impedance spectroscopy, oxygen isotope exchange, O2 TPD and H2 TPR experiments revealed a positive effect of composite interfaces on the oxygen mobility and reactivity agreeing with the ambipolar transport behavior of MIEC composite. Preliminary testing of button-size cell with functionally graded LSNF–GDC cathode layer supported on thin YSZ layer covering Ni/YSZ cermet demonstrated high and stable performance, which is promising for its practical application.
Polarization conversion metasurface design based on characteristic mode rotation and its application into wideband and miniature antennas with a low radar cross section.

In this paper, a characteristic mode rotation (CMR) method has been proposed to design a compact metasurface antenna with a low radar cross section (RCS) in a wideband. In the proposed CMR method, the incident wave dependent complex characteristic currents corresponding to the dominant characteristic modes solved by the characteristic mode method (CMM) are calculated. With the direction of the superposition of the complex characteristic currents orthogonal to that of the incident electric field in the CMR method, the metasurface subarray with wideband polarization conversion characteristic is designed. By arranging the metasurface subarray in a rotation way, a metasurface array with a compact size of 1. 28λ0×1. 28λ0 is designed for wideband RCS reduction. A miniature circle patch antenna is integrated with the metasurface array to achieve not only good radiation performance but also low observability for the in-band and the out-of-band of the antenna. Simulated and measured results demonstrate that the proposed miniature metasurface antenna designed by the CMR method has a good broadside radiation pattern, a maximal gain of 10.75 dB, and a -10 dB RCS reduction characteristic in the wide band of 6∼20.7 GHz with a fractional band of 110%.
Ursachen der chronischen Nierenschädigung in Patienten mit Lebererkrankungen – Pathophysiologie und Therapiemöglichkeiten

Zusammenfassung Eine akute oder chronische Nierenschädigung bei gleichzeitig bestehender Lebererkrankung stellt ein häufiges Problem dar und geht im weiteren klinischen Verlauf mit zahlreichen Komplikationen sowie einer gesteigerten Dialysepflichtigkeit und Mortalität einher. Die Prävalenz einer chronischen Niereninsuffizienz (CNI) bei Patienten mit Lebererkrankungen ist hoch, nicht zuletzt wegen parallel bestehender Komorbiditäten (z. B. metabolisches Syndrom, chronische Entzündungsprozesse, Hyperkoagulabilität, Hyperfibrinolyse, Diabetes mellitus, Dyslipidämie usw.). Doch nicht jede chronische Verschlechterung der Nierenretentionsparameter lässt sich auf ein hepatorenales Syndrom zurückführen. Neben diesem sind die häufigsten Ursachen der CNI bei bestehenden Lebererkrankungen die diabetische Nephropathie, die alkoholassoziierte IgA-Nephropathie, die mit Hepatitis C assoziierte membranoproliferative Glomerulonephritis und die mit Hepatitis B assoziierte membranöse Glomerulonephritis. Koexistente Erkrankungen, ähnlich bzw. parallel ablaufende pathophysiologische Mechanismen und überlappende Erscheinungsbilder stellen hinsichtlich der Ursachenfindung und entsprechenden Behandlung der CNI im Rahmen einer existenten Lebererkrankung eine Herausforderung an den Kliniker dar. Diese Übersichtsarbeit skizziert sowohl häufige als auch seltene Entitäten, die zu einer chronischen Nierenschädigung in diesem speziellen Patientenkollektiv führen, und zeigt einen Überblick zu therapeutischen Möglichkeiten.
Association reactions at low pressure. V. The CH+3/HCN system. A final wordq

The reaction of the methyl cation with hydrogen cyanide is revisited. We have confidence that we have resolved a long standing apparent contradiction of experimental results. A literature history is presented along with one new experiment and a re‐examination of an old experiment. In this present work it is shown that all of the previous studies had made consistent observations. Yet, each of the previous studies failed to observe all of the information present. The methyl cation does react with HCN by radiative association, a fact which had been in doubt. The product ions formed in the two‐body and three‐body processes react differently with HCN. The collisionally stabilized association product formed by a three‐body mechanism, does not react with HCN and is readily detected in the experiments. The radiatively stabilized association product, formed by a slow two‐body reaction, is not detected because it reacts with HCN by a fast proton transfer reaction forming the protonated HCN ion. Previous studies eit.
Reflective Debugging in Spinoza V3.0

In this paper we present an online IDE (Spinoza 3.0) for teaching Python programming in which the students are (sometimes) required to verbally reflect on their error messages and unit test failures before being allowed to modify their code. This system was designed to be used in large synchronous in-person, remote, or hybrid classes for either in-class problem solving or out-of-class homework problems. For each student and problem, the system makes a random choice about whether to require reflection on all debugging steps. If the student/problem pair required reflection, then after each time the student ran the program and received feedback as an error message or a set of unit test results, they were required to type in a description of the bug and a plan for how to modify the program to eliminate the bug. The main result is that the number of debugging steps to reach a correct solution was statistically significantly less for problems where the students were required to reflect on each debugging step. We suggest that future developers of pedagogical IDEs consider adding features which require students to reflect frequently during the debugging process.
Enabledness-based Testing of Object Protocols

A significant proportion of classes in modern software introduce or use object protocols, prescriptions on the temporal orderings of method calls on objects. This article studies search-based test generation techniques that aim to exploit a particular abstraction of object protocols (enabledness preserving abstractions (EPAs)) to find failures. We define coverage criteria over an extension of EPAs that includes abnormal method termination and define a search-based test case generation technique aimed at achieving high coverage. Results suggest that the proposed case generation technique with a fitness function that aims at combined structural and extended EPA coverage can provide better failure-detection capabilities not only for protocol failures but also for general failures when compared to random testing and search-based test generation for standard structural coverage.
A dielectric relaxation study of plasticization of poly(ethyl methacrylate) by carbon dioxide

Plasticization of poly(ethyl methacrylate) (PEMA) by CO2 is investigated by dielectric relaxation spectroscopy. The dissipation factor of a dielectric cell containing the film and air gaps is measured as a function of frequency (1–10,000 kHz) and CO2 pressure (0–60 atm) over the temperature range 35–115°C. A maximum in the frequency dependence of the dissipation factor, which is attributed to the α relaxation of PEMA, shifts to higher frequency with increasing temperature, pressure, or concentration. The apparent activation energy of the isosteric relaxation decreases from 28 to 23 kcal/mol as the concentration is increased from 0 to 90 cm3 (STP)/cm3 (polym). The relaxation peak temperature at fixed frequency decreases with increasing concentration. The effect of hydrostatic pressure on the dielectric relaxation is estimated and compared with values for the PEMA-He and PEMA-Ar systems. The plasticizing effect of sorbed CO2 is discussed on the basis of the relaxation data.
Novice Difficulties with Analyzing the Running Time of Short Pieces of Code

This work attempts to understand how novices approach runtime analysis tasks, where the number of operations performed by a given program needs to be analyzed by looking at the code. Such tasks are commonly used by instructors in courses on data structures and algorithms. The focus of this work is on the difficulties faced by novices when approaching such tasks and how novices differ from experts in how they approach these tasks. The study involved one-on-one think-aloud interviews with five instructors of an introductory data structures and algorithms course and 14 students enrolled in that course. The interviews were analyzed using a framework introduced in this study for describing the steps needed to perform runtime analysis of simple pieces of code. The study found the interviewed experts to clearly differentiate between the task of formulating a summation describing the number of operations performed by the code and the task of solving that summation to find how many operations are done. Experts in the study also showed fluency in looking at the code from different perspectives and sometimes re-wrote the code to simplify the analysis task. On the other hand, the study found several novices to make mistakes because of not explicitly tracing the code and because of not explicitly describing the number of performed operations using a summation. Many of the novices also seemed inclined to approach the analysis of nested loops by multiplying two running times, even when that is incorrect. The study concluded with a discussion of the implications of these results on the teaching and assessment of runtime analysis.
Vulnerability context and well-being factors of Indigenous community development: a study of Peninsular Malaysia

The Indigenous people of Malaysia are a heterogeneous community scattered over more than 852 villages in Peninsular Malaysia. This community has been identified to be among the poorest and marginalized in Peninsular Malaysia. This study evaluates the well-being factors as well as problems that hinder the development of an Indigenous community in Peninsular Malaysia. This article adopted a quantitative approach based on data collected through survey and 2,136 respondents were interviewed. The study reveals that the Indigenous community is likely to remain poor in terms of economic status significantly because of insufficient access to basic education and the inability of being employed. This is also due to the inability to receive support for housing, economic livelihood, and other social infrastructures. In addition, the study indicates that economic status and access to education are the most significant factors that may help improve the overall well-being of an Indigenous community. This finding also suggests that the social and environmental aspects in Peninsular Malaysia have not improved together with economic development.
Positional dependency in Murrinhpatha: expanding the typology of non-canonical morphotactics

Abstract Principles of morphotactics are a major source of morphological diversity amongst the world’s languages, and it is well-known that languages exhibit many different types of deviation from a canonical ideal in which there is a unique and consistent mapping between function and form. In this paper we present data from Murrinhpatha (non-Pama-Nyungan, northern Australia) that demonstrates a type of non-canonical morphotactics so far unattested in the literature, one which we call positional dependency. This type is unusual in that the non-canonical pattern is driven by morphological form rather than by morphosyntactic function. In this case the realisation of one morph is dependent on the position in the verbal template of another morph. Thus, it is the linearisation of morphs that conditions the morphological realisation, not the morphosyntactic feature set. Positional dependency in Murrinhpatha thus expands our typology of content-form interactions and non-canonical morphotactics with implications for our understanding of morphological structure cross-linguistically.
Physicochemical properties of South African prickly pear fruit and peel: Extraction and characterisation of pectin from the peel

Abstract The aim of this study was to determine the physicochemical properties, extract and characterise pectin from green (Morado), purple (Algerian), and orange (Gymno carpo) varieties of South African prickly pear (PP) (Opuntia ficus-indica) fruit peel. Pectin was extracted using sulphuric acid at four different pH levels (1, 2, 3, and 4) and three different microwave power levels (low 300 W, medium 400 W, and high 500 W) at a fixed time of 10 min. Yield of pectin for purple ranged from 2.9 to 13.8%, orange from 1.4 to 9.8%, and from 2.3 to 10.0% for green prickly pear peel (PPP). Maximum yield of 13.8% on purple, 10.0% on green, and 9.8% on orange was obtained at pH 1.0 and medium power level. Ash content of the extracted pectin was significantly high at 25.16, 34.26, and 36.30% for green, orange and purple PPP, respectively. However, pectin showed lower moisture content and equivalent weight. The methoxyl contents were 2.28, 2.38, and 3.86%, for anhydrouronic acid contents were 25.58, 25.93, and 38.84%, and degree of esterification was 49.87, 50.63, and 56.39% across the orange, purple, and green varieties. The PPP pectin spectra exhibited similarities in their absorption pattern to that of commercial citrus pectin.
The limits of Quediini at last (Staphylinidae: Staphylininae): a rove beetle mega‐radiation resolved by comprehensive sampling and anchored phylogenomics

Rove beetles of the tribe Quediini are abundant predators in humid microhabitats of forested, open, synanthropic or subterranean ecosystems, with just over 800 species distributed across the temperate and subtropical regions of the Northern Hemisphere. Previous molecular phylogenies included only a limited representation of this diversity but have already indicated that Quedius, containing the majority of Quediini species, is polyphyletic. Six genera, historically associated with Quediini but now Staphylininae incertae sedis, are known only from few pinned specimens and have never been sequenced. Recent synergy between target enrichment phylogenomics, low‐input sequencing of dry, pinned insect specimens and advances in alpha taxonomic knowledge have made comprehensive sampling of Quediini tractable. Here we developed a novel probe set specialized for anchored hybrid enrichment of 1229 single‐copy orthologous loci in Staphylinidae. In one of the largest target enrichment phylogenies of insects to‐date, we sequenced 201 ingroup taxa to clearly delimit monophyletic Quediini within Staphylininae and resolve relationships within this tribe, with 46% of sampled taxa derived from pinned specimens (0–45 years old). Maximum likelihood and coalescent phylogenetic analyses produced well‐resolved, congruent topologies that will serve as a framework for further exploration of this radiation and its necessary generic revision. The inclusion of nearly all remaining Staphylininae incertae sedis genera, all known only from pinned specimens, resulted in the creation of Quelaestrygonini Brunke, trib. n. and revised concepts for Cyrtoquediini and Indoquediini. Quediini was resolved as monophyletic with the transfer of Q. elevatus and Q. nigropolitus to other tribes but Quedius and its subgenera Microsaurus, Distichalius and Raphirus were shown to be para‐ or polyphyletic. Based on the results of our analyses, Velleiopsis Fairmaire, 1882 syn. n. and Megaquedius Casey, 1915 syn. n. are synonymized with Microsaurus Dejean, 1833 resulting in: Q. (Microsaurus) marginiventris (Fairmaire) comb. n. , Q. (M.) varendorffi (Reitter) comb.n. Several species of Quedius were transferred from Microsaurus to Distichalius (Q. aethiops Smetana, Q. biann Smetana, Q. cingulatus Smetana and Q. taruni Smetana), Distichalius to Raphirus (Q. fagelianus Scheerpeltz) and Microsaurus to Raphirus (Q. mixtus Eppelsheim and Q. persicus Korge).
Universality of zeta-Functions of Cusp Forms and non-Trivial zeros of the Riemann zeta-function

It is known that zeta-functions ζ(s, F ) of normalized Hecke-eigen cusp forms F are universal in the Voronin sense, i.e., their shifts ζ(s + iτ, F ), τ ∈ R, approximate a wide class of analytic functions. In the paper, under a weak form of the Montgomery pair correlation conjecture, it is proved that the shifts ζ(s+iγkh, F ), where γ1 < γ2 < . is a sequence of imaginary parts of non-trivial zeros of the Riemann zeta function and h > 0, also approximate a wide class of analytic functions.
A Systematic Survey of ML Datasets for Prime CV Research Areas - Media and Metadata

The ever-growing capabilities of computers have enabled pursuing Computer Vision through Machine Learning (i.e., MLCV). ML tools require large amounts of information to learn from (ML datasets). These are costly to produce but have received reduced attention regarding standardization. This prevents the cooperative production and exploitation of these resources, impedes countless synergies, and hinders ML research. No global view exists of the MLCV dataset tissue. Acquiring it is fundamental to enable standardization. We provide an extensive survey of the evolution and current state of MLCV datasets (1994 to 2019) for a set of specific CV areas as well as a quantitative and qualitative analysis of the results. Data were gathered from online scientific databases (e.g., Google Scholar, CiteSeerX). We reveal the heterogeneous plethora that comprises the MLCV dataset tissue; their continuous growth in volume and complexity; the specificities of the evolution of their media and metadata components regarding a range of aspects; and that MLCV progress requires the construction of a global standardized (structuring, manipulating, and sharing) MLCV “library”. Accordingly, we formulate a novel interpretation of this dataset collective as a global tissue of synthetic cognitive visual memories and define the immediately necessary steps to advance its standardization and integration.
Salt tolerance induced by hydrogen peroxide priming on seed is related to improvement of ion homeostasis and antioxidative defense in sunflower plants

Abstract Salt-induced redox and ion imbalance may lead to increased oxidative stress and impair the plant growth. However, among the many reactive oxygen species (ROS) produced under stress, hydrogen peroxide (H2O2) plays a central role in several signal transduction pathways triggering a series of physiological mechanisms and increase plant tolerance to salt stress. Thus, this study aimed to evaluate the changes in the balance of inorganic and organic solutes induced by seed priming with H2O2 in leaves and roots of sunflower plants grown under salt stress. In this study, six treatments were tested: T1 - control (absence of NaCl and absence of H2O2); T2 - salt control (presence of 100 mM NaCl and absence of H2O2); T3 − 100 mM H2O2 (12 h) + 100 mM NaCl; T4 − 10 mM H2O2 (12 h) + 100 mM NaCl; T5 − 1 mM H2O2 (24 h) + 100 mM NaCl; T6 − 0.1 mM H2O2 (36 h) + 100 mM NaCl. Our results show that, the role of H2O2 in increase of the salt tolerance is directly associated with reduction on Na+ (on average 46%) and Cl- (on average 24%) contents in the leaves, besides a positive regulation of K+ and NO3 - absorption (for three harvests). In addition, H2O2 priming also decreased the oxidative damage, mainly by increasing the activity of catalase enzyme (CAT) in leaves (on average 49% at 2nd and 3rd harvests) and roots (on average 39% at 3rd harvest).
Phase Formation, Morphology and Magnetic Properties of PbTiO3–Fe2O3 Heterostructure Ceramics

Abstract Multiferroic (1-x)PbTiO3−(x)Fe2O3 composite materials, when x = 0.1, 0.3, 0.5, 0.7 and 0.9, were prepared by solid-state reaction technique. PbTiO3 powder was synthesized with a calcination temperature of 900 °C in air. Phase formation, densification, morphology and magnetic properties of (1-x)PbTiO3−(x)Fe2O3 composites were investigated and discussed. The XRD technique was used to analyze the phase formation behavior of all specimens which shown the Fe2O3 accumulate phase with increasing Fe2O3 content. Densities of the sintered ceramics trend to decrease, possibly caused by an anomaly morphology of the specimens that related to particle packing. Also besides, the superparamagnetic behaviors were observed using a Vibrating Sample Magnetometer (VSM), which reached the maximum value at x = 0.7. In conclusion, Fe2O3 addition has been found to affect the phase formation, microstructure and magnetic properties of PbTiO3 ceramics.
