AbstractForage quality surveys can provide a variety of insights into the nutritional well‐being of herbivores. Even small differences in how much of the food eaten can be digested and used for life requisites (dry matter digestibility %; DMD) can affect performance of ruminants, and thus methods for determining forage digestibility must be accurate, repeatable, and robust among laboratories and over time. In 2013, we observed levels of DMD as determined from sequential detergent fiber assays with the filter bag method and the ANKOM fiber analyzer200/200® that were greater than expected given the plant species, season, and environmental setting. Using stockpiled and previously analyzed forage samples from Oregon, Washington, and Idaho, we evaluated whether fiber results had shifted since 2012, potential causes of the shifts, and whether results since 2012 aligned with data on ungulate performance. Beginning in 2012, our results indicated that sequential detergent fiber analysis began significantly overestimating DMD compared to the same samples analyzed using identical methodology prior to 2012. Magnitude of the difference increased as soluble fiber increased and overestimated DMD by up to 31 percentage points. We detected no changes in laboratory procedures (e.g., fiber bag design or origin of chemical solution) nor differences among laboratories using identical methodologies (e.g., Washington State University versus Dairy One) that might explain the shift, and thus were unable to pinpoint the cause. Results obtained prior to 2012 better explained ungulate performance (e.g., body fat, pregnancy, population trends) and thus we developed predictive equations (0.59 ≤ r2 ≤ 0.88) to align post‐2012 lab results with those obtained before 2012. Shifts in assay results and inconsistencies in laboratory methods have marked potential to affect inferences from studies of ruminant nutritional ecology. We provide recommendations for researchers using sequential detergent fiber analysis to measure DMD.
Multi-jet merging with TMD parton branching
Authors: Bermudez Martinez A. , Hautmann F. , Mangano M. L. 
Published: September 2022

Abstract
One of the main theoretical systematic uncertainties in studies of final states with large jet multiplicities at high-energy hadron colliders is associated with the merging of QCD parton showers and hard-scattering matrix elements. We present a method to incorporate the physics of transverse momentum recoils due to initial-state shower evolution into multi-jet merging algorithms by using the concept of transverse momentum dependent (TMD) distributions and the associated parton branching. We investigate the dependence on the merging scale and illustrate the impact of the new method at the level of both exclusive and inclusive final-state observables by studying differential jet rates, transverse momentum spectra and multiplicity distributions, using vector boson + jets events at the LHC as a case study.
NNLO study of top-quark mass renormalization scheme uncertainties in Higgs boson production
Authors: Mazzitelli Javier 
Published: September 2022

Abstract
The ambiguity in the choice of a renormalization scheme and scale for the top-quark mass leads to an additional source of theoretical uncertainty in the calculation of the Higgs boson production cross section via gluon fusion. These uncertainties were found to be dominant in the case of off-shell Higgs production at next-to-leading order in QCD for large values of the Higgs virtuality $$ {m}_H^{\ast } $$

We include the full top-quark mass dependence up to three loops in the virtual corrections, and evaluate the real contributions in the soft limit, therefore obtaining the so-called soft-virtual (SV) approximation. We construct NNLOSV predictions for off-shell Higgs boson production renormalizing the top-quark mass within both the on-shell (OS) and the $$ \overline{\mathrm{MS}} $$

We also observe that the difference between renormalization schemes is largely reduced when increasing the order of the perturbative expansion. We analyze the quality of the convergence of the perturbative series in both schemes, and find that at large invariant masses the $$ \overline{\mathrm{MS}} $$

Elliptical and purely NS superstrata
Authors: Ganchev Bogdan , Houppe Anthony , Warner Nicholas P. 
Published: September 2022

Abstract
We analyze the BPS equations in the “superstratum sector” of three-dimensional gauged supergravity. We obtain multi-parameter supersymmetric solutions that include elliptical deformations of the supertubes that underlie standard superstrata. We uplift the three-dimensional solutions to obtain the corresponding six-dimensional geometries. This yields new families of elliptically-deformed, ambi-bolar hyper-Kähler geometries in four dimensions with a non-tri-holomorphic U(1) isometry. We also find a new family of scaling superstrata whose S-dual lives entirely within the NS-sector of supergravity, and will thus be more amenable to exact analysis using string probes. In all these new superstrata, including the scaling ones, if the momentum charge is non-zero we find that the ellipse stays away from the degeneration locus in which the ellipse becomes flat.
FIMP dark matter in heterotic M-theory
Authors: Dumitru Sebastian , Ovrut Burt A. 
Published: September 2022

Abstract
Within the context of N = 1 supersymmetric heterotic M-theory, we present a “freeze-in” mechanism for producing dark matter via a “moduli portal” between the observable and hidden sectors. It is assumed that the observable sector consists of the MSSM or some physically acceptable extension of it, while the hidden sector is chosen to satisfy all physical and mathematical constraints. Dark matter production processes are examined for two fundamental types of hidden sectors; those whose gauge bundle structure group contains an anomalous U(1) and those whose structure group is non-Abelian and anomaly free. The couplings of the dilaton and the “universal” modulus to all fields of the observable and hidden sectors are presented and analyzed. These interactions are then combined to produce a moduli portal from a thermal bath of observable sector particles to the hidden sector. These processes are then analyzed for both anomalous and non-anomalous cases. It is shown that only the uncharged hidden sector matter scalars can play the role of dark matter and that these are predominantly produced during the “reheating” epoch on the observable sector. Within the context of both an anomalous and non-anomalous hidden sector, we calculated the dark matter “relic density”. We show that in both cases, for a wide choice of moduli vacua, one can correctly predict the observed relic density. For the anomalous U(1) case, we choose a specific physically acceptable vacuum within the context of the B − L MSSM and show that one precisely obtains the measured dark matter relic abundance.

Authors: Li Xiaojiao , Liu Qingwei , Xu Jingxu , Huang Chencui , Hua Qianqian , Wang Haili , Ma Teng , Huang Zhaoqin 
Published: September 2022

Abstract
Objectives
This study is aimed to establish a fusion model of radiomics-based nomogram to predict the renal function of autosomal dominant polycystic kidney disease (ADPKD).

Methods
One hundred patients with ADPKD were randomly divided into training group (n = 69) and test group (n = 31). The radiomics features were extracted from T1-weighted fat suppression images (FS-T1WI) and T2-weighted fat suppression images (FS-T2WI). Decision tree algorithm was employed to build radiomics model to get radiomics signature. Then multivariate logistic regression analysis was used to establish the radiomics nomogram based on independent clinical factors, conventional MR imaging variables and radiomics signature. The receiver operating characteristic (ROC) analysis and Delong test were used to compare the performance of radiomics model and radiomics nomogram model, and the decision curve to evaluate the clinical application value of radiomics nomogram model in the evaluation of renal function in patients with ADPKD.

Results
Fourteen radiomics features were selected to establish radiomics model. Based on FS-T1WI and FS-T2WI sequences, the radiomics model showed good discrimination ability in training group and test group [training group: (AUC) = 0.7542, test group (AUC) = 0.7417]. The performance of radiomics nomogram model was significantly better than that of radiomics model in all data sets [radiomics model (AUC) = 0.7505, radiomics nomogram model (AUC) = 0.8435, p value = 0.005]. The analysis of calibration curve and decision curve showed that radiomics nomogram model had more clinical application value.

Conclusion
radiomics analysis of MRI can be used for the preliminary evaluation and prediction of renal function in patients with ADPKD. The radiomics nomogram model shows better prediction effect in renal function evaluation, and can be used as a non-invasive renal function prediction tool to assist clinical decision-making.

More than a simple epithelial layer: multifunctional role of echinoderm coelomic epithelium

Published: September 2022

Abstract
In echinoderms, the coelomic epithelium (CE) is reportedly the source of new circulating cells (coelomocytes) as well as the provider of molecular factors such as immunity-related molecules. However, its overall functions have been scarcely studied in detail. In this work, we used an integrated approach based on both microscopy (light and electron) and proteomic analyses to investigate the arm CE in the starfish Marthasterias glacialis during different physiological conditions (i.e., non-regenerating and/or regenerating). Our results show that CE cells share both ultrastructural and proteomic features with circulating coelomocytes (echinoderm immune cells). Additionally, microscopy and proteomic analyses indicate that CE cells are actively involved in protein synthesis and processing, and membrane trafficking processes such as phagocytosis (particularly of myocytes) and massive secretion phenomena. The latter might provide molecules (e.g., immune factors) and fluids for proper arm growth/regrowth. No stem cell marker was identified and no pre-existing stem cell was observed within the CE. Rather, during regeneration, CE cells undergo dedifferentiation and epithelial-mesenchymal transition to deliver progenitor cells for tissue replacement. Overall, our work underlines that echinoderm CE is not a “simple epithelial lining” and that instead it plays multiple functions which span from immunity-related roles as well as being a source of regeneration-competent cells for arm growth/regrowth.

Published: September 2022

Abstract
Objective
We retrospectively analyzed risk factors on in-hospital mortality in CRRT-therapy patients with open cardiac surgery (CS)-induced acute kidney injury (AKI), to provide the clinical basis for predicting and lowering the in-hospital mortality after CS.

Methods
84 CS-AKI patients with CRRT were divided into survival and death groups according to discharge status, and the perioperative data were analyzed with R version 4.0.2.

Results
There were significant differences between the two groups, including: urea nitrogen, Sequential Organ Failure Assessment (SOFA) score and vasoactive-inotropic score (VIS) on the first day after operation; VIS just before CRRT; SOFA score and negative balance of blood volume 24 h after CRRT; the incidence rate of bleeding, severe infection and MODS after operation; and the interval between AKI and CRRT. Univariate logistic regression analysis showed that SOFA score and VIS on the first day after operation; VIS just before CRRT; VIS and negative balance of blood volume 24 h after CRRT; the incidence rate of bleeding, infection and multiple organ dysfunction syndrome (MODS) after operation; bootstrap resampling analysis showed that SOFA score and VIS 24 h after CRRT, as well as the incidence of bleeding after operation were the independent risk factors.

Conclusion
Maintaining stable hemodynamics and active prevention of bleeding are expected to decrease the in-hospital mortality.

AbstractUnder arid and semi-arid climates, adopting the appropriate tools for alleviating water deficit impacts is a critical factor that affects the physiological characteristics and yield of sunflower. Therefore, in order to find promising field practices in sunflower cultivation, the strip plots design in randomized complete block arrangement was used to examine the effects of two irrigation regimes as 100% (FI) and 85% (DI) of crop evapotranspiration and five antioxidant treatments on physiological and agronomic traits, yield response factor, and irrigation water use efficiency (IWUE) of sunflower. The antioxidant treatments involved two rates of ascorbic acid (150 and 300 mg L−1) and two rates of citric acid (250 and 500 mg L−1), in addition to the check treatment (tap water). The study was conducted for two growing seasons of 2019 and 2020 at the Experimental Farm of Ain Shams University, Egypt, located in a semi-arid environment. Findings showed that exogenous application of higher rate of ascorbic acid, i.e. 300 mg L−1 with FI exhibited the highest increase of chlorophyll a, chlorophyll b and the lowest proline content compared to other interaction treatments. Seed yield was significantly higher with FI plus ascorbic acid 300 mg L−1 and DI plus ascorbic acid 300 mg L−1 treatments than with their counterpart check treatment in both growing seasons. Under DI, IWUE was improved with antioxidant-treated plants compared to untreated plants. Yield response factor as an indicator of crop tolerance to drought was higher than the unit (> 1) under all ascorbic acid and citric acid levels. It could be concluded that ascorbic acid and citric acids partially mitigated the reductions in growth and yield caused by low water supply. However, yield response factor demonstrated that the crop is still sensitive to drought. Thus, other applicable patterns should be adopted to increase the yield potential of sunflower for counteracting the adverse impacts of drought.
A Two-Degree-of-Freedom Knee Model Predicts Full Three-Dimensional Tibiofemoral and Patellofemoral Joint Motion During Functional Activity
Authors: Guan Shanyuanye , Gray Hans A. , Thomeer Lucas T. , Pandy Marcus G. 
Published: September 2022

AbstractSix kinematic parameters are needed to fully describe three-dimensional (3D) bone motion at a joint. At the knee, the relative movements of the femur and tibia are often represented by a 1-degree-of-freedom (1-DOF) model with a single flexion–extension axis or a 2-DOF model comprising a flexion–extension axis and an internal–external rotation axis. The primary aim of this study was to determine the accuracy with which 1-DOF and 2-DOF models predict the 3D movements of the femur, tibia and patella during daily activities. Each model was created by fitting polynomial functions to 3D tibiofemoral (TF) and patellofemoral (PF) kinematic data recorded from 10 healthy individuals performing 6 functional activities. Model cross-validation analyses showed that the 2-DOF model predicted 3D knee kinematics more accurately than the 1-DOF model. At the TF joint, mean root-mean-square (RMS) errors across all activities and all participants were 3.4°|mm (deg or mm) for the 1-DOF model and 2.4°|mm for the 2-DOF model. At the PF joint, mean RMS errors were 4.0°|mm and 3.9°|mm for the 1-DOF and 2-DOF models, respectively. These results indicate that a 2-DOF model with two rotations as inputs may be used with confidence to predict the full 3D motion of the knee-joint complex.
Nonhomogeneous expanding flows in hyperbolic spaces
Authors: Pipoli Giuseppe 
Published: September 2022

AbstractIn the present paper, we consider star-shaped mean convex hypersurfaces of the real, complex and quaternionic hyperbolic space evolving by a class of nonhomogeneous expanding flows. For any choice of the ambient manifold, the initial conditions are preserved and the long-time existence of the flow is proved. The geometry of the ambient space influences the asymptotic behaviour of the flow: after a suitable rescaling, the induced metric converges to a conformal multiple of the standard Riemannian round metric of the sphere if the ambient manifold is the real hyperbolic space; otherwise, it converges to a conformal multiple of the standard sub-Riemannian metric on the odd-dimensional sphere. Finally, in every case, we are able to construct infinitely many examples such that the limit does not have constant scalar curvature.
Viable healthcare supply chain network design for a pandemic
Authors: Alizadeh Mehdi , Pishvaee Mir Saman , Jahani Hamed , Paydar Mohammad Mahdi , Makui Ahmad 
Published: September 2022

AbstractThe recent COVID-19 pandemic revealed that healthcare networks must have a flexible and effective structure. In this study, we develop a viable healthcare network design for a pandemic using a multi-stage stochastic approach. We propose a multi-level network that includes health centers, computed tomography scan centers, hospitals, and clinics. Patients have conditions to returning to normal life or quarantining at home. Three objectives are defined: maximizing the probability of patient recovery, minimizing the costs of all centers in the network, and minimizing the Coronavirus death rate. We investigate a real case study in Iran to demonstrate the model’s applicability. Finally, we compare the healthcare supply chain network design in a pandemic with a normal situation to advise how the network can continue to remain viable.
Argumentation in Philosophical Controversies
Authors: Leal Fernando , Marraud Hubert 
Published: September 2022

AbstractAnyone interested in philosophical argumentation should be prepared to study philosophical debates and controversies because it is an intensely dialogical, and even contentious, genre of argumentation. There is hardly any other way to do them justice. This is the reason why the present special issue addresses philosophical argumentation within philosophical debates. Of the six articles in this special issue, one deals with a technical aspect, the diagramming of arguments, another contrasts two moments in philosophical argumentation, Antiquity and the twentieth century, focusing on the use of refutation, and the remaining four analyze particular philosophical controversies. The controversies analyzed differ significantly in their characteristics (time, extension, media, audience,…). Hopefully, this varied sample will illuminate some salient aspects of philosophical argumentation, its representation and variations throughout history. We are fully aware that, given the scarcity of previous studies of philosophical debates from the perspective of argumentation theory, the following specimens of analysis must have several shortcomings. But it is a well-known adage that the hardest part is the beginning. That is what we tried to achieve here, no more, but no less either.
Impact of instructor on-slide presence in synchronous e-learning
Authors: Katai Zoltan , Iclanzan David 
Published: September 2022

AbstractAs a consequence of the COVID-19 pandemic, many higher education programs had to switch to synchronous online teaching. Teachers suddenly faced pressing unaddressed challenges, such as how to better transfer their “presence” from the traditional classroom to the online space in a way that keeps students engaged. This paper explores new venues for increasing the quality of synchronous online learning. We propose the notion of broad on-slide presence, pillared on an increased instructor expressiveness and an elevated instructor slide-content interaction. We conducted four studies to investigate the benefits of delivering lectures in this format, using a mixed methods research approach. We combined survey methodology with transversal design and structural equation modelling with qualitative methodology using discourse analysis of teacher interviews. Results revealed a significant increase in perceived knowledge gain and attentional engagement, and an improved and more personal student experience. At the same time, the instructor’s broader on-slide presence also resulted in an increased teacher satisfaction.
