Nomogram to Predict Radiation Enteritis in Cervical Squamous Cell Carcinoma

Purpose To investigate the risk factors of radiation enteritis in patients with cervical cancer after radiotherapy. Patients and Methods Retrospective analysis 90 cervical cancer patients receiving radiation therapy from January 2019 to May 2021 in Hefei Cancer Hospital, Chinese Academy of Sciences. The patients were divided into radiation enteritis group and control group according to the radiation enteritis, the continuous variable were analyzed by ROC to obtain the best truncation value, and univariate and multifactorial logistic regression models analyzed the independent risk factors for radiation enteritis in cervical cancer patients. Nomogram was constructed and evaluated based on independent risk factors. Results The radiation enteritis incidence rate was 35.56%. Univariate analysis found that hemoglobin (OR=4.25, 95% CI=1.43~13.73), albumin (OR=2.33, 95% CI=0.95~5.83), hypertension (OR=3.57, 95% CI=1.24~10.90), sigmoid colon V45(OR=0.41, 95% CI=0.15~1.03), external radiation dose (OR=0.45, 95% CI=0.18~1.08), age (OR=2.27, 95% CI=0.90~6.18), total T lymphocyte count (OR=2.4, 95% CI=0.97~6.29)(p<0.1) are risk factors for radiation enteritis. Multivariate logistic regression analysis found that hemoglobin (p=0.001, OR=13.22, 95% CI=3.03~72.65), albumin (p=0.003, OR=6.76, 95% CI=2.08~25.67), total T lymphocyte count (p=0.015, OR=4.79, 95% CI=1.45~13.38) were independent risk factors for radiation enteritis. Based on the above predictors, a nomogram model is established, and the area under the model fit, C-index, and ROC curve indicates that the model has good prediction efficiency and differentiation. Conclusion Hemoglobin, albumin, and total T lymphocyte count are risk factors for radiation enteritis in cervical cancer patients under radiotherapy, the nomogram model based on the above risk factors has good predictive efficacy and can provide a reference for radiation enteritis prediction.
APPROXIMATE ANALYTICAL SOLUTIONS FOR PRIMARY CHATTER IN THE NON-LINEAR METAL CUTTING MODEL

This paper considers an accepted model of the metal cutting process dynamics in the context of an approximate analysis of the resulting non-linear differential equations of motion. The process model is based upon the established mechanics of orthogonal cutting and results in a pair of non-linear ordinary differential equations which are then restated in a form suitable for approximate analytical solution. The chosen solution technique is the perturbation method of multiple time scales and approximate closed-form solutions are generated for the most important non-resonant case. Numerical data are then substituted into the analytical solutions and key results are obtained and presented. Some comparisons between the exact numerical calculations for the forces involved and their reduced and simplified analytical counterparts are given. It is shown that there is almost no discernible difference between the two thus confirming the validity of the excitation functions adopted in the analysis for the data sets used, these being chosen to represent a real orthogonal cutting process. In an attempt to provide guidance for the selection of technological parameters for the avoidance of primary chatter, this paper determines for the first time the stability regions in terms of the depth of cut and the cutting speed co-ordinates.
Penetration and energy-loss theory of electrons in solid targets

Starting from a simple atomic model giving the potential between electrons and atoms as V(r) = Ze2as−1/srs with the empirical value s=fraction six-fifths, we combine the diffusion effect due to multiple collisions and the energy retardation in accordance with a modified Thomson-Whiddington law, with the scattering cross section in the Lenard absorption law. On this basis, consistent expressions are obtained for the fraction of transmitted electrons in amorphous solid targets, the backscattering fraction with depth, the fraction of electrons absorbed per unit mass-thickness and the depth-dose function, which are in good agreement with experiments over the energy range 10-1000 keV. A diffusion model represented by a sphere whose centre is located at the maximum energy dissipation depth, related to the diffusion depth and the range, is found to agree well with experiments.
The First Swift BAT Gamma-Ray Burst Catalog

We present the first Swift Burst Alert Telescope (BAT) catalog of gamma-ray bursts (GRBs), which contains bursts detected by the BAT between 2004 December 19 and 2007 June 16. This catalog (hereafter the BAT1 catalog) contains burst trigger time, location, 90% error radius, duration, fluence, peak flux, and time-averaged spectral parameters for each of 237 GRBs, as measured by the BAT. The BAT-determined position reported here is within 1.75′ of the Swift X-Ray Telescope (XRT)-determined position for 90% of these GRBs. The BAT T90 and T50 durations peak at 80 and 20 s, respectively. From the fluence-fluence correlation, we conclude that about 60% of the observed peak energies, Epeakobs, of BAT GRBs could be less than 100 keV. We confirm that GRB fluence to hardness and GRB peak flux to hardness are correlated for BAT bursts in analogous ways to previous missions’ results. The correlation between the photon index in a simple power-law model and Epeakobs is also confirmed. We also report the current status for the on-orbit BAT calibrations based on observations of the Crab Nebula.
Fine-Grained Object Detection in Remote Sensing Images via Adaptive Label Assignment and Refined-Balanced Feature Pyramid Network

Object detection in high-resolution remote sensing images remains a challenging task due to the uniqueness of its viewing perspective, complex background, arbitrary orientation, etc. For fine-grained object detection in high-resolution remote sensing images, the high intra-class similarity is even more severe, which makes it difficult for the object detector to recognize the correct classes. In this article, we propose the refined and balanced feature pyramid network (RB-FPN) and center-scale aware (CSA) label assignment strategy to address the problems of fine-grained object detection in remote sensing images. RB-FPN fuses features from different layers and suppresses background information when focusing on regions that may contain objects, providing high-quality semantic information for fine-grained object detection. Intersection over Union (IoU) is usually applied to select the positive candidate samples for training. However, IoU is sensitive to the angle variation of oriented objects with large aspect ratios, and a fixed IoU threshold will cause the narrow oriented objects without enough positive samples to participate in the training. In order to solve the problem, we propose the CSA label assignment strategy that adaptively adjusts the IoU threshold according to statistical characteristics of oriented objects. Experiments on FAIR1M dataset demonstrate that the proposed approach is superior. Moreover, the proposed method was applied to the fine-grained object detection in high-resolution optical images of 2021 Gaofen challenge. Our team ranked sixth and was awarded as the winning team in the final.
Pressure dependence of Sm:YAG fluorescence to 50 GPa: A new calibration as a high pressure scale

The pressure‐induced wavelength shift of laser excited fluorescence from samarium doped yttrium aluminum garnet (Sm:YAG) was measured up to 50 GPa at room temperature against the R1 shift of ruby. The intense peaks between 618 and 611 nm were analyzed as triplet, Y1, Y2, and Y3, by curve fitting analysis using the Lorentzian function. The Y1 (λ0=618 nm) peak was the strongest peak up to 40 GPa, while the Y2 (λ0=616 nm) peak became the strongest above it. Based upon the pressure dependency of the Y1 and Y2 peaks, the following pressure scales are proposed: P=3.25×Δλ(Y1)–0.015×Δλ2(Y1); P=4.03×Δλ(Y2)–0.055×Δλ2(Y2). As the temperature dependence of the fluorescence shift of Sm:YAG is negligibly small, these pressure scales will be useful for high pressure and high temperature experiments using a diamond anvil cell.
Group Recommendation Based on Heterogeneous Graph Algorithm for EBSNs

Emerging event-based social networks (EBSNs), such as Meetup, have grown rapidly and become popular in recent years. EBSNs differ from conventional social networks such as Facebook in that they not only involve online social interactions but also include offline, in-person interactions. Thus, EBSNs are naturally heterogeneous and possess more valuable social information. Group recommendations in EBSNs are typically only based on the interest information filled in by users, or friends’ group information. Both these methods may not well reflect users’ real intentions. In this study, we propose a recommender system to predict groups that may interest EBSN users, based on a novel heterogeneous augmented graph method and a random walk with restart algorithm. In this approach, online and offline social interactions are combined into a single heterogeneous augmented graph capturing all useful relationships, including user-to-group relationships, user-to-event relationships, user-to-attribute relationships, and group-to-attribute relationships, and among others. To our knowledge, this work is the first attempt to apply a random walk algorithm into group recommendation in EBSNs. Extensive experiments on Meetup datasets demonstrate that our proposed recommender system achieves better results in terms of recall, precision, F-Measure and MRR metrics in comparison with the other four commonly used algorithms, including random recommendation, interest-based recommendation, interest- and neighborhood-based recommendation, and Katz Centrality. The significant recommendation performance of our approach may further enhance user satisfaction of EBSNs. Moreover, our approach to group recommendation may also be extended to other recommendation-related applications such as event or friend recommendation.
Extrapolation of perturbation-theory expansions by self-similar approximants

The problem of extrapolating asymptotic perturbation-theory expansions in powers of a small variable to large values of the variable tending to infinity is investigated. The analysis is based on self-similar approximation theory. Several types of self-similar approximants are considered and their use in different problems of applied mathematics is illustrated. Self-similar approximants are shown to constitute a powerful tool for extrapolating asymptotic expansions of different natures.
Components of spaces of curves with constrained curvature on flat surfaces

Let $S$ be a complete flat surface, such as the Euclidean plane. We obtain direct characterizations of the connected components of the space of all curves on $S$ which start and end at given points in given directions, and whose curvatures are constrained to lie in a given interval, in terms of all parameters involved. Many topological properties of these spaces are investigated. Some conjectures of L. E. Dubins are proved.
Variational models for phase separation

The paper deals with the asymptotic behaviour (as" ! 0) of a familyF"(u,v) of integral functionals in the framework of phase separation. In order to obtain a selection criterion for the minima of the usual double-well, non-convex free energy involving the phase-variable u, we add a gradient term in a new variable v which is related to u through the L 2 -distance between u and v, weighted by a coefficient . We prove that the limit as " ! 0 is a minimal area model with a surface tension of non-local form. The well-known Modica‐Mortola constant can be recovered in this setting as a limit case when ! +1.
Semi-algebraic horizontal subvarieties of Calabi-Yau type

We study horizontal subvarieties $Z$ of a Griffiths period domain $\mathbb D$. If $Z$ is defined by algebraic equations, and if $Z$ is also invariant under a large discrete subgroup in an appropriate sense, we prove that $Z$ is a Hermitian symmetric domain $\mathcal D$, embedded via a totally geodesic embedding in $\mathbb D$. Next we discuss the case when $Z$ is in addition of Calabi-Yau type. We classify the possible VHS of Calabi-Yau type parametrized by Hermitian symmetric domains $\mathcal D$ and show that they are essentially those found by Gross and Sheng-Zuo, up to taking factors of symmetric powers and certain shift operations. In the weight three case, we explicitly describe the embedding $Z\hookrightarrow \mathbb D$ from the perspective of Griffiths transversality and relate this description to the Harish-Chandra realization of $\mathcal D$ and to the Kor\'anyi-Wolf tube domain description. There are further connections to homogeneous Legendrian varieties and the four Severi varieties of Zak.

A bibliometric analysis of the psychologization of human resource management

Abstract Despite years of discussion, whether and to what extent human resource management (HRM) has been psychologized remains controversial. We consider HRM psychologization as indicated by a disciplinary (i.e., the relative contribution of psychology and other fields to HRM research) and an inter-disciplinary component (i.e., knowledge integration of psychology and other fields in HRM research). Accordingly, we apply two bibliometric methods (i.e., citation and co-citation analysis) to a sample of 6,709 articles published in six HRM journals from 2000 to 2021. Overall, psychology became more influential as a citation source in HRM research but integrated more closely with other intellectual sources in the period examined. In addition, HRM psychologization was contingent on HRM journals, the first authors’ countries, and HRM subdomains. This study presents an enriched pattern of psychologization as well as substantial quantitative evidence that confirms, counters, or extends prior findings.
A mechanism for layer formation in a double-diffusive fluid

The dynamics of layer formation by salt fingers from the uniform temperature and salinity gradients is studied by direct numerical simulations of the two-dimensional Navier–Stokes equations. It is shown that formation of steps in the model is caused by the parametric variation of the flux ratio ($\gamma\,{=}\,{\overline{wT}}/{\overline{wS}}$) as a function of the density ratio ($R$), which leads to an instability of equilibrium with uniform stratification. These unstable large-scale perturbations continuously grow in time until well-defined layers are formed. Subsequent evolution of the numerical staircases is explained by considering the secondary instabilities of a series of salt finger interfaces.
Holonomy of the Ising model form factors

We study the Ising model two-point diagonal correlation function C(N, N) by presenting an exponential and form factor expansion in an integral representation which differs from the known expansion of Wu, McCoy, Tracy and Barouch. We extend this expansion, weighting, by powers of a variable λ, the j-particle contributions, f(j)N,N, in the form factor expansion. The corresponding λ-extension of the two-point diagonal correlation function, C(N, N; λ), is shown, for arbitrary λ, to be a solution of the sigma form of the Painlevé VI equation introduced by Jimbo and Miwa in their isomonodromic approach to the Ising model. Fuchsian linear differential equations for the form factors f(j)N,N are obtained for j ⩽ 9 and shown to have both a ‘Russian-doll’ nesting and a decomposition of the corresponding linear differential operators as a direct sum of operators equivalent to symmetric powers of the second-order linear differential operator associated with the elliptic integral E. From this, we show that each f(j)N,N is unexpectedly simple, being expressed polynomially in terms of the elliptic integrals E and K. In contrast, we exhibit some mathematical objects, built from these form factors f(j)N,N, which break the direct sum of symmetric powers decomposition, with its associated polynomial expressions. First we show that the scaling limit of these differential operators, and form factors, breaks the direct sum structure but not the ‘Russian-doll’ structure. Secondly, we show that the previous λ-extension of two-point diagonal correlation functions, C(N, N; λ), is, for singled-out values λ = cos(πm/n), (m, n integers), also solutions of Fuchsian linear differential equations. These solutions of Painlevé VI are not polynomial in E and K but are actually algebraic functions, being associated with modular curves.
Kerr-Newman Solutions with Analytic Singularity and no Closed Timelike Curves

It is shown that the Kerr-Newman solution, representing charged and rotating stationary black holes, admits analytic extension at the singularity. This extension is obtained by using new coordinates, in which the metric tensor becomes smooth on the singularity ring. On the singularity, the metric is degenerale - its determinant cancels. The analytic extension can be naturally chosen so that the region with negative r no longer exists, eliminating by this the closed timelike curves normally present in the Kerr and Kerr-Newman solutions. On the extension proposed here the electromagnetic potential is smooth, being thus able to provide non-singular models of charged spinning particles. The maximal analytic extension of this solution can be restrained to a globally hyperbolic region containing the exterior universe, having the same topology as the Minkowski spacetime. This admits a spacelike foliation in Cauchy hypersurfaces, on which the information contained in the initial data is preserved.
Resonances within nonperturbative methods in field theories

We study the stability of solitonlike solutions of a classical relativistic field theory with logarithmic nonlinearities. For a given charge (not greater than a certain value g/sub max/) the model exhibits a stable state and an unstable one. The latter state, instead of being nonphysical, can be interpreted as a resonance. Problems related to the semiclassical quantization of this theory are also discussed. All calculations are done in any number of spatial dimensions. (AIP)
Reachability and Controllability Problems for the Heat Equation on a Half-Axis

In the paper, problems of controllability, approximate controllability, reachability and approximate reachability are studied for the control system $w_t=w_{xx}$, $w(0,\cdot)=u$, $x>0$, $t\in(0,T)$, where $u\in L^\infty(0,T)$ is a control. It is proved that each end state of this system is approximately reachable in a given time $T$, and each its initial state is approximately controllable in a given time $T$. A necessary and sufficient condition for reachability in a given time $T$ is obtained in terms of solvability a Markov power moment problem. It is also shown that there is no initial state that is null-controllable in a given time $T$. The results are illustrated by examples.
The charge $2$ monopole via the ADHMN construction

Recently we have shown how one may use use integrable systems techniques to implement the ADHMN construction and obtain general analytic formulae for the charge n su(2) Euclidean monopole. Here we do this for the case of charge 2: so answering an open problem of some 30 years standing. A comparison with known results and other approaches is made and new results presented.
PEDICLE SCREW CONVERGENCE IMPACT ON THE STABILITY OF TRANSPEDICULAR FIXATION SPINE MODEL IN CYCLIC LOADING: BIOMECHANICAL STUDY

The principle of this study is experimental measurement and description of behavior of transpedicular fixation during cyclic loading due to convergence of screw insertion. Investigations were made of three configurations of assemblies of posterior stabliization with converging screws at 0°, 20° and 40°. The experiment was inspired ASTM Standard F1717 and modified to minimize the effect of other parameters. The MTS 858.2 Mini Bionix testing system was used during the experiment, in conjunction with the Interface 1010ACK load cell. Data processing and analysis were carried out by Matlab R 20102b, MathWorks. The probed assemblies were cyclically loaded until structural failure occurred, always at the screwbone (or PUR block) interface, i.e., the "windshield wiper" effect. The measurement results show that while the rigidity of the assembly increases with increased convergence of transpedicular screws, they also indicate an increased initial rate of assembly damage accumulation, together with assembly failure during a reduced number of cyclic loading cycles. The mechanical behavioral study of transpedicular fixation is limited by the conditions of simplification of interpretation of complex movements and spinal pathophysiology in the attempt to minimize the effect of other parameters and exaggerated measurements.
Solar p-mode phenomenology

New observations of solar p-mode amplitudes and line widths are presented, along with a phenomenological discussion of the excitation and damping of the modes. A surprising amount of structure is seen in the measured mode line widths as a function of frequency, which at present is unexplained. It is shown that the energy flux required to keep the p-modes excited to their observed amplitudes is of the same order of magnitude as the nonthermal energy flux required to heat the chromosphere. Thus it is not inconceivable that acoustic modes play some role in heating the solar atmosphere. 10 references.
On the severe convective storm of 29 October 2013 in the Balearic Islands: observational and numerical study

On 29 October 2013, a severe squall line developed to the west of the Balearic Islands (Spain) ahead of an advancing cold front and then crossed the archipelago. We first provide an observational characterization of the event based on surface reports, remote sensing products, radiosoundings and synoptic information. We also achieve, by means of numerical experiments, new insights into the kinematic and thermodynamic factors that governed the genesis and evolution of the linear convective system. Radar and satellite images confirm the fast movement and linear shape of the system, with an indication of a possible transition into a bow‐echo structure during its later stages. The synoptic setting at mid‐upper tropospheric levels was dominated by a cold trough extended over western Europe, associated with a jet stream located downstream. Convection evolved under the right entrance region of the jet and initiated under the crucial influence of a surface low that developed over the Mediterranean Sea ahead of the cold front. The low not only cooperated with the upper‐level dynamical forcing to erode a capping inversion initially present over the Balearics and moisten the atmospheric column above, but also shaped and enhanced a convergence line along which the first convective cells grew and self‐aggregated. This scenario is confirmed by numerical simulations of the case, which also emphasize the important role of regional topography in the production of the aforementioned maritime convergence through the mesoscale modulation of the low‐level flow. Additional simulations show that (i) the destabilization of the low‐level air mass necessary for triggering and feeding an organized convective system on 29 October 2013 was attributable to prior evaporation from the Mediterranean and (ii) sea‐surface temperatures appear to be critical for a successful fine‐grid numerical forecast of the mode, degree of severity, timing and track of the convective precipitation system.
