Live‐view 4D GRASP MRI: A framework for robust real‐time respiratory motion tracking with a sub‐second imaging latency
Authors: Feng Li 
Published: May 2023

PurposeTo propose a framework called live‐view golden‐angle radial sparse parallel (GRASP) MRI for low‐latency and high‐fidelity real‐time volumetric MRI.MethodsLive‐view GRASP MRI has two stages. The first one is called an off‐view stage and the second one is called a live‐view stage. In the off‐view stage, 3D k‐space data and 2D navigators are acquired alternatively using a new navi‐stack‐of‐stars sampling scheme. A 4D motion database is then generated that contains time‐resolved MR images at a sub‐second temporal resolution, and each image is linked to a 2D navigator. In the live‐view stage, only 2D navigators are acquired. At each time point, a live‐view 2D navigator is matched to all the off‐view 2D navigators. A 3D image that is linked to the best‐matched off‐view 2D navigator is then selected for this time point. This framework places the typical acquisition and reconstruction burden of MRI in the off‐view stage, enabling low‐latency real‐time 3D imaging in the live‐view stage. The accuracy of live‐view GRASP MRI and the robustness of 2D navigators for characterizing respiratory variations and/or body movements were assessed.ResultsLive‐view GRASP MRI can efficiently generate real‐time volumetric images that match well with the ground‐truth references, with an imaging latency below 500 ms. Compared to 1D navigators, 2D navigators enable more reliable characterization of respiratory variations and/or body movements that may occur throughout the two imaging stages.ConclusionLive‐view GRASP MRI represents a novel, accurate, and robust framework for real‐time volumetric imaging, which can potentially be applied for motion adaptive radiotherapy on MRI‐Linac.
Recycling of polyamides: Processes and conditions
Authors: Hirschberg Valerian , Rodrigue Denis 
Published: May 2023

AbstractPolyamides (PA) are a family of engineering thermoplastics used in a wide range of applications including automotive, building, construction, separation processes, textiles, and so forth. This is related to their good properties (mechanical and thermal) which can also be modified by additives, other polymers (blends and multilayers) and fillers (composites). But these complex systems (several components) make the final materials more difficult to recycle. In this review, basic statistics on the production rate of polyamides are presented and the different recycling methods are reported to compare their advantages and limitations with respect to economics and technical analyses. The discussion includes biological, chemical, mechanical, physical, and thermal treatments to reintroduce, as much as possible, the parts after their end‐of‐service. Finally, a general conclusion on the current state of PA recycling is presented with several openings for future developments to satisfy the concept of circular economy and general sustainability.

AbstractBACKGROUNDAs an invasive pest from North America, grey squirrels (GSs; Sciurus carolinensis Gmelin) are displacing native squirrels in Europe. However, the climatic niche and range dynamics of GSs in Europe remain largely unknown. Through niche and range dynamic models, we investigated climatic niche and range shifts between introduced GSs in Europe and native GSs in North America.RESULTSGSs in North America can survive in more variable climatic conditions and have much wider climatic niche breadth than do GSs in Europe. Based on climate, the potential range of GSs in Europe included primarily Britain, Ireland, and Italy, whereas the potential range of GSs in North America included vast regions of western and southern Europe. If GSs in Europe could occupy the same climatic niche space and potential range as GSs in North America, they would occupy an area ca. 2.45 times the size of their current range. The unfilling ranges of GSs in Europe relative to those of GSs in North America were primarily in France, Italy, Spain, Croatia, and Portugal.CONCLUSIONOur observations implied that GSs in Europe have significant invasion potential, and that range projections based on their occurrence records in Europe may underestimate their invasion risk. Given that small niche shifts between GSs in Europe and in North America could lead to large range shifts, niche shifts could be a sensitive indicator in invasion risk assessment. The identified unfilling ranges of the GS in Europe should be prioritized in combating GS invasions in the future. © 2023 Society of Chemical Industry.
Hydroxysafflor yellow A attenuates allergic response of ovalbumin induced allergic rhinitis via Nrf2/HO‐1 and inflammatory signaling pathways

Published: May 2023

AbstractAllergic reaction is the most common nasal conditions worldwide and it will remain throughout life. The symptoms of an allergic reaction include sneezing, itching, hives, swelling, difficulty breathing, and a runny nose. Hydroxysafflor yellow A (HYA) is a flavonoid compound which is the active phyto‐constituent of flower of Carthamus tinctorius L., and exhibited the various medicinal activities like antioxidant, anti‐inflammatory and cardiovascular protective effects. This study aimed to assess the efficacy and mode of action of HYA against the allergic rhinitis induced by ovalbumin in mice. HYA was given orally to the Swiss BALB/s mice once daily, 1 h before, they were challenged with ovalbumin (OVA) via intranasal administration, after that the mice were sensitized via intraperitoneal injection of OVA. Allergic nasal symptoms, body weight, spleen weight, OVA‐specific immunoglobulins, inflammatory cytokines, Th17 cytokines and Th17 transcription factors also estimated. HYA had a significant (p < .001) effect on body weight and reduced spleen weight. It effectively decreased the nasal symptoms of allergy such as sneezing, rubbing, and redness. HYA significantly reduced the level of malonaldehyde (MDA) and improved levels of superoxide dismutase (SOD), glutathione peroxidase (GPx), catalase (CAT) and glutathione (GSH). It also remarkably decreased the levels of Th2 cytokines and Th17 transcription factors like RAR‐related orphan receptor gamma (ROR‐γ), signal transducer and activator of transcription 3 (STAT3) and phosphor signal transducer and activator of transcription 3 (p‐STAT3), while increasing levels of nuclear factor erythroid 2‐related factor 2 (Nrf2) and heme oxygenase‐1 (HO‐1). The treatment with HYA improved the lung histology in mice with allergic rhinitis. The results suggest that HYA may have therapeutic potential against ovalbumin‐induced allergic rhinitis in mice, by altering the Th17/Treg balance and improving the Nrf2/HO‐1 signaling pathway.

Published: May 2023

Abstract
The interpretation of present and future neutrino experiments requires accurate theoretical predictions for neutrino-nucleus scattering rates. Neutrino structure functions can be reliably evaluated in the deep-inelastic scattering regime within the perturbative QCD (pQCD) framework. At low momentum transfers (Q2 ≲ few GeV2), inelastic structure functions are however affected by large uncertainties which distort event rate predictions for neutrino energies Eν up to the TeV scale. Here we present a determination of neutrino inelastic structure functions valid for the complete range of energies relevant for phenomenology, from the GeV region entering oscillation analyses to the multi-EeV region accessible at neutrino telescopes. Our NNSFν approach combines a machine-learning parametrisation of experimental data with pQCD calculations based on state-of-the-art analyses of proton and nuclear parton distributions (PDFs). We compare our determination to other calculations, in particular to the popular Bodek-Yang model. We provide updated predictions for inclusive cross sections for a range of energies and target nuclei, including those relevant for LHC far-forward neutrino experiments such as FASERν, SND@LHC, and the Forward Physics Facility. The NNSFν determination is made available as fast interpolation LHAPDF grids, and it can be accessed both through an independent driver code and directly interfaced to neutrino event generators such as GENIE.
On scalar charges and black hole thermodynamics
Authors: Ballesteros Romina , Gómez-Fayrén Carmen , Ortín Tomás , Zatti Matteo 
Published: May 2023

Abstract
We revisit the first law of black hole thermodynamics in 4-dimensional theories containing scalar and Abelian vector fields coupled to gravity using Wald’s formalism and a new definition of scalar charge as an integral over a 2-surface which satisfies a Gauss law in the background of stationary black-hole spacetimes. We focus on ungauged supergravity-inspired theories with symmetric sigma models whose symmetries generate electric-magnetic dualities leaving invariant their equations of motion. Our manifestly duality-invariant form of the first law is compatible with the one obtained by of Gibbons, Kallosh and Kol. We also obtain the general expression for the scalar charges of a stationary black hole in terms of the other physical parameters of the solution and the position of the horizon, generalizing the expression obtained by Pacilio for dilaton black holes.

Published: May 2023

Abstract
We provide, through the framework of extended geometry, a geometrisation of the duality symmetries appearing in magical supergravities. A new ingredient is the general formulation of extended geometry with structure group of non-split real form. A simple diagrammatic rule for solving the section constraint by inspection of the Satake diagram is derived.

Abstract
Gravitational subsystems with boundaries carry the action of an infinite-dimensional symmetry algebra, with potentially profound implications for the quantum theory of gravity. We initiate an investigation into the quantization of this corner symmetry algebra for the phase space of gravity localized to a region bounded by a 2-dimensional sphere. Starting with the observation that the algebra $$ \mathfrak{sdiff} $$
sdiff
(S2) of area-preserving diffeomorphisms of the 2-sphere admits a deformation to the finite-dimensional algebra $$ \mathfrak{su} $$
su
(N), we derive novel finite-N deformations for two important subalgebras of the gravitational corner symmetry algebra. Specifically, we find that the area-preserving hydrodynamical algebra $$ \mathfrak{sdiff}\left({S}^2\right){\oplus}_{\mathcal{L}}{\mathbb{R}}^{S^2} $$

Additionally, we present a number of novel results related to the various algebras appearing, including a detailed analysis of the asymptotic expansion of the $$ \mathfrak{su} $$

Zusammenfassung
Hintergrund und Fragestellung
Zerebrale Schädigungen können als infantilen Zerebralparese (ICP) oder durch andere Erkrankungen vorliegen. Durch Störung des Muskeltonus entwickelt sich häufig eine neurogene Hüftdezentrierung. Ein hüftrekonstruierender Eingriff kann die Mobilität und Pflegequalität der Kinder wesentlich verbessern. Derartige operative Versorgungen werden durch Abwertungen im DRG-System finanziell benachteiligt. In der Folge ziehen sich kinderorthopädische Abteilungen aus diesem Versorgungskonzepten zurück, es besteht das Risiko einer Unterversorgung.

Material und Methode
Ziel dieser retrospektiven Studie war eine Wirtschaftlichkeitsanalyse von kinderorthopädischen Eingriffen am Beispiel der neurogenen Hüftdezentrierung. Dazu wurde bei Patienten mit ICP und mit anderen zerebralen Schädigungen die Erlös-Kosten-Situation an einem Haus der Maximalversorgung im Zeitraum 2019–2021 untersucht.

Ergebnisse
Über den gesamten Analysezeitraum zeigt sich eine Verlustsituation. Bei Kindern ohne frühkindliche Hirnschädigung noch deutlicher als in der Gruppe der Patienten mit ICP. Während hüftrekonstruktive Eingriffe bei Kindern mit ICP zunächst 2019 noch kostendeckend zu erbringen waren, sind auch diese Versorgungen seit 2021 defizitär.

Diskussion
Obwohl die Unterscheidung zwischen einer ICP und anderen kindlichen Hirnschäden im kinderorthopädischen Versorgungskonzept keine Rolle spielt, zeigt sich vor allem die nicht-CP-Gruppe im DRG-System deutlich unterfinanziert. Insgesamt offenbart sich die negative wirtschaftliche Bilanz der Kinderorthopädie. Kinder mit Behinderung können in der aktuellen Auslegung des DRG-Systems an einem universitären Zentrum der Maximalversorgung nicht kostendeckend versorgt werden.

Published: May 2023

Abstract
Purpose
The aim of the presented case is to describe an unprecedented innervation of the coracobrachialis longus muscle by the radial nerve.

Methods
An 82-year-old body donor at death was subjected to a routine anatomical dissection for teaching and research purposes at the Department of Anatomical Dissection and Donation in Lodz, Poland.

Results
We have found an additional branch of the radial nerve, which departed from it just below its beginning. Its initial section ran alongside the radial nerve in the axilla, then headed medially accompanying superior ulnar collateral artery. Then, it reaches the coracobrachialis longus muscle and is the only one to innervate it.

Conclusions
The brachial plexus (BP) is very variable and well understood. Nevertheless, we must remember that there may still be variations in its structure, which may involve problems at every stage of diagnosis and treatment of diseases associated with its structures. Their knowledge is extremely important.
Adaptive LASSO estimation for functional hidden dynamic geostatistical models
Authors: Maranzano Paolo , Otto Philipp , Fassò Alessandro 
Published: May 2023

AbstractWe propose a novel model selection algorithm based on a penalized maximum likelihood estimator (PMLE) for functional hidden dynamic geostatistical models (f-HDGM). These models employ a classic mixed-effect regression structure with embedded spatiotemporal dynamics to model georeferenced data observed in a functional domain. Thus, the regression coefficients are functions. The algorithm simultaneously selects the relevant spline basis functions and regressors that are used to model the fixed effects. In this way, it automatically shrinks to zero irrelevant parts of the functional coefficients or the entire function for an irrelevant regressor. The algorithm is based on an adaptive LASSO penalty function, with weights obtained by the unpenalised f-HDGM maximum likelihood estimators. The computational burden of maximisation is drastically reduced by a local quadratic approximation of the log-likelihood. A Monte Carlo simulation study provides insight in prediction ability and parameter estimate precision, considering increasing spatiotemporal dependence and cross-correlations among predictors. Further, the algorithm behaviour is investigated when modelling air quality functional data with several weather and land cover covariates. Within this application, we also explore some scalability properties of our algorithm. Both simulations and empirical results show that the prediction ability of the penalised estimates are equivalent to those provided by the maximum likelihood estimates. However, adopting the so-called one-standard-error rule, we obtain estimates closer to the real ones, as well as simpler and more interpretable models.
An art painting style explainable classifier grounded on logical and commonsense reasoning
Authors: Costa Vicent , Alonso-Moral Jose M. , Falomir Zoe , Dellunde Pilar 
Published: May 2023

AbstractThis paper presents the art painting style explainable classifier named ANYXI. The classifier is based on art specialists’ knowledge of art styles and human-understandable color traits. ANYXI overcomes the principal flaws in the few art painting style classifiers in the literature. In this way, we first propose, using the art specialists’ studies, categorizations of the Baroque, Impressionism, and Post-Impressionism. Second, we carry out a human survey with the aim of validating the appropriateness of the color features used in the categorizations for human understanding. Then, we analyze and discuss the accuracy and interpretability of the ANYXI classifier. The study ends with an evaluation of the rationality of explanations automatically generated by ANYXI. We enrich the discussion and empirical validation of ANYXI by considering a quantitative and qualitative comparison versus other explainable classifiers. The reported results show how ANYXI is outstanding from the point of view of interpretability while keeping high accuracy (comparable to non-explainable classifiers). Moreover, automated generations are endowed with a good level of rationality.

AbstractObjectivesTwo-dimensional (2D) through-plane phase-contrast (PC) cine flow imaging assesses shunts and valve regurgitations in paediatric CMR and is considered the reference standard for Clinical quantification of blood Flow (COF). However, longer breath-holds (BH) can reduce compliance with possibly large respiratory manoeuvres altering flow. We hypothesize that reduced BH time by application of CS (Short BH quantification of Flow) (SBOF) retains accuracy while enabling faster, potentially more reliable flows. We investigate the variance between COF and SBOF cine flows.MethodsMain pulmonary artery (MPA) and sinotubular junction (STJ) planes were acquired at 1.5 T in paediatric patients by COF and SBOF.Results21 patients (mean age 13.9, 10–17y) were enrolled. The BH times were COF mean 11.7 s (range 8.4–20.9 s) vs SBOF mean 6.5 s (min 3.6–9.1 s). The differences and 95% CI between the COF and SBOF flows were LVSV -1.43 ± 13.6(ml/beat), LVCO 0.16 ± 1.35(l/min) and RVSV 2.95 ± 12.3(ml/beat), RVCO 0.27 ± 0.96(l/min), QP/QS were SV 0.04 ± 0.19, CO 0.02 ± 0.23. Variability between COF and SBOF did not exceed intrasession variation of COF.ConclusionSBOF reduces breath-hold duration to 56% of COF. RV flow by SBOF was biased compared to COF. The variation (95% CI) between COF and SBOF was similar to the COF intrasession test–retest 95% CI.
Mixed-frequency quantile regressions to forecast value-at-risk and expected shortfall
Authors: Candila Vincenzo , Gallo Giampiero M. , Petrella Lea 
Published: May 2023

AbstractAlthough quantile regression to calculate risk measures is widely established in the financial literature, when considering data observed at mixed-frequency, an extension is needed. In this paper, a model is built on a mixed-frequency quantile regressions to directly estimate the Value-at-Risk (VaR) and the Expected Shortfall (ES) measures. In particular, the low-frequency component incorporates information coming from variables observed at, typically, monthly or lower frequencies, while the high-frequency component can include a variety of daily variables, like market indices or realized volatility measures. The conditions for the weak stationarity of the daily return process are derived and the finite sample properties are investigated in an extensive Monte Carlo exercise. The validity of the proposed model is then explored through a real data application using two energy commodities, namely, Crude Oil and Gasoline futures. Results show that our model outperforms other competing specifications, on the basis of some popular VaR and ES backtesting test procedures.
Unlocking the dual black box of GHRMP & EGOC for sustainable environmental performance in developing economies: can green workplace behavior and green passion transmit the real change?
Authors: He Weihua , Mushtaq Naveed , Jan Laraeb 
Published: May 2023

AbstractIn recent years, there has been a growing emphasis on environmental sustainability, resulting in the emergence of Green Human Resource Management (GHRM) practices. Studies have shown that the implementation of GHRM practices can enhance a company's Environmental Performance (EP) and promote the development of Enablers of Green Organizational Culture (EGOC), which can ultimately lead to sustained improvements in environmental performance over the long term. However, there is still a lack of research on Green Workplace Behavior (GWB) and Green Passion (GP). To address this gap, a study was conducted on a large-scale sample of 308 pharmaceutical workers. The study examined the dual mediation impact of major facilitators of Green Organization Culture and GWB on GHRM, and the regulation of GP. Smart Pls 3.0 was used for analyzing the measurement and structural model. The findings indicate that the dual mediation of EGOC and GWB, along with the regulation of GP, significantly enhances the EP levels of organizations. These findings have significant implications for pharmaceutical company managers who are interested in developing strategic HR strategies for sustainable development. The study's results provide guidance on how managers can motivate their employees to engage in green initiatives in their daily activities, and GHRM practices offer a practical way to enhance EP and sustainable development. However, the contribution of Human Resource Management to sustainable development remains limited in the literature. Therefore, it is important for businesses to recognize the significance of environmental sustainability and adopt GHRM practices to improve their EP levels. The environment and natural resources around the world have been severely impacted by the aggressive growth of human economic expansion, and there is an urgent need for social efforts to address this situation. The adoption of GHRM practices can help businesses to develop specialized skills and enhance their contribution to sustainable development. The literature suggests that GHRM practices are a viable and practical solution to enhance environmental performance and promote sustainable development.
