Two W-subtype contact binaries: GQ Boo and V1367 Tau

Two contact binaries, GQ Boo and V1367 Tau, were observed and analysed with a new method to obtain the absolute parameters. The light-curve analysis shows that both of them are obvious W-subtype contact binaries, with much more massive but apparently cooler components (M2/M1 2 and 4, T2/T1 0.95 and 0.94). The orbital periods were studied using the O–C diagrams, and it is thought that the minima timings were heavily affected by the longstanding magnetic activities on the star surface, so the minima timings cannot represent the real period changes. The mass–radius relationships were proposed by the light-curve analysis alone, which is equivalent to the mean density. The density and temperature can determine the other absolute parameters in most of the time. With the almost complete star parameter space provided by PARSEC, approximate masses and radii were obtained (0.52 ± 0.08 M and 1.01 ± 0.15 M for GQ Boo, and 0.22 ± 0.01 M and 0.92 ± 0.06 M for V1367 Tau). The mass–radius relationship is a neglected useful tool to calculate the mass and radius, especially for the detached binaries.
Circle patterns, topological degrees and deformation theory

By using topological degree theory, this paper extends Koebe-Andreev-Thurston theorem to include obtuse intersection angles. Then it considers the characterization problem of circle patterns having the same preassigned contact graphs and dihedral angle datum. To be specific, the article develops the deformation theory by showing that the space of all such patterns could be depicted with the product of the Teichmuller spaces of its interstices. As corollaries, the density property of the set of packable surfaces and the ideal circle patterns are discussed.
Early Prediction of Mortality after Birth Asphyxia with the nSOFA

(1) Birth asphyxia is a major cause of delivery room resuscitation. Subsequent organ failure and hypoxic–ischemic encephalopathy (HIE) account for 25% of all early postnatal deaths. The neonatal sequential organ failure assessment (nSOFA) considers platelet count and respiratory and cardiovascular dysfunction in neonates with sepsis. To evaluate whether nSOFA is also a useful predictor for in-hospital mortality in neonates (≥36 + 0 weeks of gestation (GA)) following asphyxia with HIE and therapeutic hypothermia (TH), (2) nSOFA was documented at ≤6 h of life. (3) A total of 65 infants fulfilled inclusion criteria for TH. All but one infant received cardiopulmonary resuscitation and/or respiratory support at birth. nSOFA was lower in survivors (median 0 [IQR 0–2]; n = 56, median GA 39 + 3, female n = 28 (50%)) than in non-survivors (median 10 [4–12], p < 0.001; n = 9, median GA 38 + 6, n = 4 (44.4%)). This was also observed for the respiratory (p < 0.001), cardiovascular (p < 0.001), and hematologic sub-scores (p = 0.003). The odds ratio for mortality was 1.6 [95% CI = 1.2–2.1] per one-point increase in nSOFA. The optimal cut-off value of nSOFA to predict mortality was 3.5 (sensitivity 100.0%, specificity 83.9%). (4) Since early accurate prognosis following asphyxia with HIE and TH is essential to guide decision making, nSOFA (≤6 h of life) offers the possibility of identifying infants at risk of mortality.
Exploring the Use of Alumina Nanofluid as Emergency Coolant for Nuclear Fuel Bundle

Nanofluids are suspensions of nanosized particles in any base fluid that show significant enhancement of their heat transfer properties at modest nanoparticle concentrations. Due to enhanced thermal properties at low nanoparticle concentration, it is a potential candidate for utilization in nuclear heat transfer applications. In the last decade, there have been few studies which indicate possible advantages of using nanofluids as a coolant in nuclear reactors during normal as well as accidental conditions. In continuation with these studies, the utilization of nanofluids as a viable candidate for emergency core cooling in nuclear reactors is explored in this paper by carrying out experiments in a scaled facility. The experiments carried out mainly focus on quenching behavior of a simulated nuclear fuel rod bundle by using 1% Alumina nanofluid as a coolant in emergency core cooling system (ECCS). In addition, its performance is compared with water. In the experiments, nuclear decay heat (from 1.5% to 2.6% reactor full power) is simulated through electrical heating. The present experiments show that, from heat transfer point of view, alumina nanofluids have a definite advantage over water as coolant for ECCS. Additionally, to assess the suitability of using nanofluids in reactors, their stability was investigated in radiation field. Our tests showed good stability even after very high dose of radiation, indicating the feasibility of their possible use in nuclear reactor heat transfer systems.
INTERACTIVE LEARNING MEDIA FOR CRITICAL AND CREATIVE THINKING SKILLS DEVELOPMENT

The parameters of a nation's success can be evaluated by how revolution 4.0 education advances science and technology. This is also a new difficulty in the educational realm. In order to prepare for Revolution 4.0, students must have talents as provisions. Contextual learning is one way for helping students enhance their critical and creative thinking skills. Simple harmonic motion is one of the ideas that is relevant to everyday life, hence there are many contextual problems that may be handled. To enhance students' critical and creative thinking skills, the researchers developed interactive learning media focused on the concept of simple harmonic motion. The type of research was research and development (R&D) with ADDIE model. This study examined at interactive learning media oriented at critical and creative thinking skills on the concept of simple harmonic motion. The research goal was to create learning media with critical and creative thinking skills based on the simple harmonic motion concepts. The product validity was reviewed by three physics lecturer at FMIPA UNP. Product validity has an average value of 0.83 in the very valid category.
Dependence of Induced Biological Damage on the Energy Distribution and Intensity of Clinical Intra-Operative Radiotherapy Electron Beams

The survival fraction of epithelial HaCaT cells was analysed to assess the biological damage caused by intraoperative radiotherapy electron beams with varying energy spectra and intensities. These conditions were achieved by irradiating the cells at different depths in water using nominal 6 MeV electron beams while consistently delivering a dose of 5 Gy to the cell layer. Furthermore, a Monte Carlo simulation of the entire irradiation procedure was performed to evaluate the molecular damage in terms of molecular dissociations induced by the radiation. A significant agreement was found between the molecular damage predicted by the simulation and the damage derived from the analysis of the survival fraction. In both cases, a linear relationship was evident, indicating a clear tendency for increased damage as the averaged incident electron energy and intensity decreased for a constant absorbed dose, lowering the dose rate. This trend suggests that the radiation may have a more pronounced impact on surrounding healthy tissues than initially anticipated. However, it is crucial to conduct additional experiments with different target geometries to confirm this tendency and quantify the extent of this effect.
Consistent formulation of ship motions in time-domain simulations by use of the results of the strip theory

Based on the three-dimensional time-domain impulse response function (IRF) and frequency-domain hydrodynamic coefficients, such as the infinite frequency added mass and damping, and radiation restoring coefficients, the IRF method is used in this work to obtain consistent formulations of linear radiation forces and ship motions. The new developments are twofold. First, the hydrodynamic added mass at infinite frequency and radiation damping in the time domain are theoretically derived using the strip theory. Second, via Kramers–Kronig (K–K) relationship for forward speed, it is observed that the added-mass and damping coefficients in the frequency domain and radiation restoring coefficients in the time domain should satisfy the K–K relationship to obtain the linear hydrodynamics in the time domain consistent with those from the frequency domain in strip theory. Following the K–K relationship and the frequency-domain added-mass and damping coefficients obtained by the strip theory, the new expressions of radiation restoring coefficients are derived. Finally, numerical validations are performed to confirm the consistent formulation proposed in this work.

Microfluidic technology, including fabrication methodologies, materials, and working modules, are touched upon. Finally, the current shortcomings on the implementation of the microfluidic technology in the forensic field are discussed along with the future perspectives.
A Variable Stiffness Actuation Based Robotic Hand Designed for Interactions

This research presents the design, modeling, and control for a bio-inspired robotic hand with antagonistic variable stiffness (AVS). A key design character is the integrated modular finger unit. The modular finger unit is developed based on the variable stiffness actuation principle and has physical impact absorption and stiffness adjustment capabilities to achieve safer grasping and manipulation in interactions and adjustable system bandwidth. Compared with the design of the previous version, the finger unit is optimized in terms of mechanism, cable path, transmission gap, and manufacturing process, and specially designed torque sensors are added to achieve the force perception of the fingertip in three dimensions. A modularized finger unit integrating mechanical parts, sensors, and electronic devices with more compact size, higher precision, and low friction is developed, which eventually lead to the implementation of the fully actuated AVS hand with three fingers and eight degrees of freedom (DOF). The hand controller hardware developed based on a field programmable gate array (FPGA) chip is integrated in the palm. These have guaranteed the real-time and stable grasping and manipulation performance of the hand.
Comparison of primary hepatic neuroendocrine tumors and non-hepatitis B non-hepatitis C hepatocellular carcinoma on contrast-enhanced ultrasound

Objective The purpose of this study was to compare the sonographic features of primary hepatic neuroendocrine tumors (PHNETs) to those of non-hepatitis B and non-hepatitis C hepatocellular carcinoma (NBNC-HCC) on contrast-enhanced ultrasound (CEUS). Materials and methods Fourteen patients with a mean age of 56.9 ± 12.2 (SD) years with histopathologically confirmed PHNET were included in the study. Twenty-eight patients with a mean age of 58.5 ± 10.4 years with histopathologically confirmed NBNC-HCC were randomly selected as the control group. The clinical data, conventional ultrasound and CEUS features were retrospectively analyzed between PHNET and NBNC-HCC. Results PHNET was more common in women (57.1%, 8/14 cases), and NBNC-HCC was more common in men (75.0%, 21/28) (P=0.040). No significant differences were observed in etiology, tumor marker, and liver function between the two group (P>0.05). Conventional ultrasound revealed that the tumor size of PHNET (10.1 ± 4.7 cm) was larger than that of NBNC-HCC (5.9 ± 3.8 cm) (P=0.006). NBNC-HCC was predominantly hypoechoic, while the echogenicity of PHNET varied (P=0.001). On CEUS, 57.1% (8/14) of PHNETs showed heterogeneous hyperenhancement, whereas 77.0% (21/28) of NBNC-HCC presented homogeneous hyperenhancement (P=0.015). Furthermore, 35.7% (5/14) of PHNETs showed early washout (onset of washout <60 s), which was significantly different from that of NBNC-HCC (3.7%, 1/28) (P=0.005). Conclusion CEUS is helpful in discriminating between PHNET and NBNC-HCC. PHNETs mainly present as a single mass with a large size (>10 cm) in the liver. The CEUS showed that most PHNETs exhibited heterogeneous enhancement in the arterial phase, washout in the portal venous and late phases and early washout being more likely than NBNC-HCC. However, more imaging features need to be evaluated in a larger sample.
A marker band folgen stratigraphy for the Cenomanian Chalk of England and its extension to northen Germany and France

: Jeans, C.V. 2023. A marker band folgen stratigraphy for the Cenomanian Chalk of England and its extension to northen Germany and France. Acta Geologica Polonica , 73 (2), 135–180. Warszawa. A novel stratigraphical scheme within the Folge Concept is described for the Cenomanian Chalk of England that is particularly suitable for investigating the regional changes in the lithofacies, diagenesis, geochemistry, and mineralogy of the sediments of the Chalk Sea leading up to the Cenomanian–Turonian Oceanic Anoxic Event. It is based on “isochronous” marker bands defined largely by calcitic macrofossil assemblages, and it avoids problems caused by the poor or non-preservation of ammonite assemblages and lateral changes in chalk lithofacies. Eight folgen are based on one, two, or more marker bands. Their sequences, lithologies and calcitic macrofossil assemblages are described from 33 exposures in the Northern Chalk Province of England. The folgen are named, in ascending order, the Belchford, Stenigot, Dalby, Bigby, Candlesby, Nettleton, Louth and Flixton, after villages in Lincolnshire and Yorkshire, England. The folgen are traced throughout the Transitional and Southern Chalk provinces of England. They are present in the Cenomanian chalk of northern Germany and northwest France. Regionally, an individual folge may display considerable vertical and lateral variation in general lithology and lithofacies whilst still maintaining their defining marker bands. The possibility of further refinement to the scheme is discussed.
Search for supersymmetry in the first √s = 13 TeV pp-collisions using the αT variable with the CMS detector

An inclusive search for supersymmetry is performed in final states with jets and missing transverse energy, in the first pp-collisions at a centre-of-mass energy of √ s = 13 TeV. The dimensionless kinematic variable, αT, is employed to discriminate between events with genuine and misreconstructed missing energy, providing sensitivity to signatures with low hadronic activity. The data sample analysed corresponds to an integrated luminosity of 2.3 fb−1 collected by the CMS detector at the LHC in 2015. The search is categorised in total jet multiplicity, multiplicity of jets arising from b-quarks and the total hadronic energy. The results are interpreted in the context of squark and gluino pair produced simplified models. In addition, a study of a new jet algorithm for the Level-1 calorimeter trigger upgrade to operate effectively in conditions exceeding the LHC design instantaneous luminosity is presented. The performance of the upgrade algorithm jet and energy sum triggers at high luminosity is evaluated and the effectiveness of several different pileup subtraction techniques compared.
Identification of a Yielding Zone Using Dynamic Characteristics and Bayesian Neural Networks

Possible yielding of the cross-section of a structure can significantly decrease the safety margin of an investigated structure. The cross-section yielding causes a change of structure stiffness and, further, dynamic characteristics (eigenvalues and eigenvectors). The measurement of the changes of the dynamic parameters [2,6] may provide information necessary to identify the location and the extent of the yielding zone. The procedure applied in the previous papers by the author, see [4,5], involved the dynamic characteristics of the initial structure without yielding of cross-section. Furthermore, a simulated location of measurement points (accelerometers) was chosen arbitrary by the author. The present paper shows the identification of the yielding zones on the basis of the changes of the eigenfrequencies and selected elements of eigenvectors. The changes are caused either by the appearance of yielding or by the application of the additional, so called control load (in Fig. 1 the value and the location of control load are called K and lk, respectively). Characteristics of the initial structure are not involved. Moreover, the location of up to four measurement points, and the number of investigated eigenvalues and eigenvectors, are also optimized.
An improved measurement model of binocular vision using geometrical approximation

In order to improve the precision of a binocular vision measurement system, an effective binocular vision measurement method, named geometrical approximation, is proposed. This method can optimize the measurement results by geometrical approximation operation based on the principles of optimization theory and spatial geometry. To evaluate the properties of the proposed method, both simulative and practical experiments are carried out. The influence of image noise and focal length error on measurement results is discussed. The results show that measurement performance of the proposed method is manifested well. Besides, the proposed method is also compared with Bundle adjustment and least squares method in a practical experiment. The experiment results indicate that the average error, calculated by using the proposed method, is 0.076 mm less than Bundle adjustment’s 0.085 mm, and only half of the least squares method’s 0.146 mm. At the meantime, the proposed method enjoys a high level of computational efficiency when compared to Bundle adjustment. Since no nonlinear iteration optimization is involved, this method can be applied readily to real time on-line measurements.
COMBINING ABILITY ANALYSIS FOR SEED YIELD AND RELATED TRAITS IN PEAS OF INDIAN AND EXOTIC ORIGIN

Seventy five F, hybrids produced in a line x tester mating fashion, their 15 lines and five testers were evaluated in two environments to study combining ability for nine yield and related traits in pea. Additive gene action contributed significantly in the inheritance of days to flowering, days to maturity, plant height and seed weight while nonadditive gene action prevailed in the inheritance of pods per plant, seeds per pod, seed yield per plant, biological yield per plant and harvest index. LMR 20 emerged as the most promising parent for seed yield per plant and related traits; Alaska 81 for early flowering: Pusa 10 for early maturity, dwarfness and seed weight; LMR 20 for pods per plant and biological yield per plant. Garifield for seeds per pod and PI 280064 for harvest index were the best general combiners for respective traits. The cross HUP 1 x Pusa 10 was most outstanding hybrid as it exhibited high SCA effect and heterosis over better parent. The correlation coefficient r between the GCA effects and mean of parents was significantly correlated for most of the characters. Implications of genotype x environment interaction on combining ability has been discussed.
On the limits of inferring biophysical parameters of RBP-RNA interactions from in vitro RNA Bind’n Seq data

We develop a thermodynamic model describing the binding of RNA binding proteins (RBP) to oligomers in vitro. We apply expectation-maximization to infer the specificity of RBPs, represented as position-specific weight matrices (PWMs), by maximizing the likelihood of RNA Bind’n Seq data from the ENCODE project. We demonstrate that the model can reproduce known specificities for well-studied proteins and that in some cases we predict novel, longer binding motifs. However, the model does not recover all the motifs that are in principle known, indicating that the data is not well explained by a single underlying biophysical model. Our code is publicly available.
Prediction of 2-[18F]FDG PET-CT SUVmax for Adrenal Mass Characterization: A CT Radiomics Feasibility Study

Simple Summary Adrenal masses represent a common incidental finding at imaging exams such as computed tomography (CT) and magnetic resonance imaging performed for unrelated reasons. Encompassing both benign and malignant entities, these lesions can prove challenging to classify. 2-[18F]FDG PET-CT is a recognized imaging modality for the characterization of indeterminate adrenal masses, but it is an expensive imaging modality and involves radiation exposure. To reduce the number of required scans and identify a less invasive potential alternative, we investigated whether CT radiomics could be used to predict the diagnostic parameter obtained using 2-[18F]FDG PET-CT (namely SUVmax). However, in our retrospective cohort of 179 adrenal masses and 150 PET-CT scans (of which 66 without iodine contrast injection), no correlation was found between the radiomics synthetic value (RadSV) and 2-[18F]FDG PET-CT SUVmax. This preliminary finding suggests that it might not be possible to use CT radiomics to reduce 2-[18F]FDG PET-CT referrals, confirming the role as problem solving tool of this imaging modality. Abstract Background: Indeterminate adrenal masses (AM) pose a diagnostic challenge, and 2-[18F]FDG PET-CT serves as a problem-solving tool. Aim of this study was to investigate whether CT radiomics features could be used to predict the 2-[18F]FDG SUVmax of AM. Methods: Patients with AM on 2-[18F]FDG PET-CT scan were grouped based on iodine contrast injection as CT contrast-enhanced (CE) or CT unenhanced (NCE). Two-dimensional segmentations of AM were manually obtained by multiple operators on CT images. Image resampling and discretization (bin number = 16) were performed. 919 features were calculated using PyRadiomics. After scaling, unstable, redundant, and low variance features were discarded. Using linear regression and the Uniform Manifold Approximation and Projection technique, a CT radiomics synthetic value (RadSV) was obtained. The correlation between CT RadSV and 2-[18F]FDG SUVmax was assessed with Pearson test. Results: A total of 725 patients underwent PET-CT from April 2020 to April 2021. In 150 (21%) patients, a total of 179 AM (29 bilateral) were detected. Group CE consisted of 84 patients with 108 AM (size = 18.1 ± 4.9 mm) and Group NCE of 66 patients with 71 AM (size = 18.5 ± 3.8 mm). In both groups, 39 features were selected. No statisticallyf significant correlation between CT RadSV and 2-[18F]FDG SUVmax was found (Group CE, r = 0.18 and p = 0.058; Group NCE, r = 0.13 and p = 0.27). Conclusions: It might not be feasible to predict 2-[18F]FDG SUVmax of AM using CT RadSV. Its role as a problem-solving tool for indeterminate AM remains fundamental.
