Plasmonic spin induced Imbert–Fedorov shift

Abstract The spin angular momentums of surface plasmon polaritons (SPPs) on chiral material interfaces and the Imbert–Fedorov shifts of linearly polarized light beams are investigated. Compared to a traditional TM-polarized SPP having a transverse spin, the SPP on a chiral material interface also has a longitudinal spin component, resulting from the nature that this new kind of SPP is a hybrid of TE and TM-polarized evanescent waves. When a light beam is incident on a sandwich structure composed of chiral material, prisms, and metal layers, in which the SPP is supported, the reflection and transmission processes can be analogous to the transport of a photon in a waveguide QED system. The SPP with longitudinal spin can be excited by the incident wave and the reflected and transmitted beams carry the spin features of the SPP. Moreover, the beams exhibit large Imbert–Fedorov shifts stemming from the spin–orbit coupling even for a linearly polarized incident beam. The shifts are determined by the longitudinal spin angular momentum and excitation coefficient of the SPP. This present work extends the study of photonic spin–orbit coupling and provides an important platform to investigate the plasmonic spin.

Влияние эксклавности и уровня доходов населения на потребительские предпочтения пациентов на рынке медицинских услуг

The article presents the results of a qualitative analysis of the influence of exclavity and the level of income of the population on the consumer preferences of patients in the medical services market using the Kaliningrad region as an example. Economic disparity in access to healthcare services contributes to the psychographic stratification of healthcare consumer preferences. Territorial isolation from the country and the proximity of foreign countries leave an imprint on the social and economic life of the population of an exclave subject and commitment to medical tourism. M a t e r i a l s a n d m e t h o d s . In the period from September to November 2022, a one-time comparative study of consumer preferences for choosing a country and a medical organization in the medical services market of 773 working-age residents of the Russian Federation was planned and conducted. All respondents were stratified into two groups according to their place of residence: residents of the Central Federal District and the Kaliningrad Region. The groups were comparable in terms of gender and age. Methods used: open online survey, qualitative analysis, statistical. The significance of differences in the percentages of the trait was estimated by the Fisher angular transformation coefficient (φ) with a given confidence level of 95%. R e s u l t s . The influence of exclavity and income level on consumer preferences for choosing a medical organization has been established. The features of the priority motivators for the choice of public, private or foreign medical services of the respondents of the Kaliningrad region are revealed. The comfort of receiving medical services (“lack of queues”) was 1,4 times more likely to motivate the choice of private medicine among respondents in the Kaliningrad region compared to respondents in other regions. The demand for the services of private and foreign clinics in the exclave territory is proportional to the level of income. Medical tourism services were used by 28,7% of respondents from the exclave territory who prefer private medicine. C o n c l u s i o n . A distinctive feature of consumers of medical services in the exclave Kaliningrad region is the increase in demand for private medicine and treatment abroad in proportion to the increase in income levels. Respondents from the exclave territory are 1,4 times more likely to choose private clinics and 23,9 times more likely to use medical tourism services compared to residents of the Central Federal District. Every fourth respondent in the Kaliningrad region does not trust the quality of training of doctors in the Russian Federation. Transport accessibility of the EU countries, dissatisfaction with the level of training of medical personnel, the lack of a number of medical services in the Russian Federation, the ability to realize the desire to combine treatment with a trip abroad with a sufficient level of income of the population in the exclave region, along with a shortage of medical personnel in the subject, contribute to increasing the attractiveness of private medical organizations, import of medical services and outflow of patients abroad. Recommendations are given to increase the attractiveness of state medicine in the exclave territory.

3D density structure of upper mantle beneath the Antarctic plate: The influence of Moho depth

In this study, we explore the impact of using different Moho surfaces on the reconstruction of the upper mantle geophysical parameters. The study area is the subsurface of the Antarctica continent. Using the optimization program of Sequential Integrated Inversion (SII) and the gravity anomalies synthetized by a global Gravity Field Model (GFM), we reconstructed the upper mantle density and the related 3D distribution of the ρ-vSV couplings down to the depth of 400 km, with a lateral resolution of 0.5° × 0.5°. Here, we present the results obtained for four models, built with four different Moho surfaces. A correlation analysis showed that different Moho structures affect the optimization of the intensity of the anomalies and the ρ-vSV couplings. The possibility of having both a density model and a 3D distribution of the ρ-vSV couplings enables us to highlight several significant features for all models that are not disclosed by seismic tomography. Among them, a trend of positive, presumably compositional anomalies suggests the contribution of the Lambert Rift System (LRS) to the Gamburstev Mountains (GSM) uplift, which in turn may have influenced the formation of the Maud Subglacial Basin (MSB). A continuous low-density anomaly and positive ρ-vSV phase coupling anomaly, extending from the northwestern side of the Transantarctic Mountains (TAM) to Victoria Land, support the thermal buoyancy force as the causative element of the formation of the TAM. A circumscribed negative density anomaly extending up to depth of 365 km, which is associated to a negative variation in the angular coefficients of the ρ-vSV couplings, indicates the presence of an active magmatic system in the upper mantle or a Cenozoic mantle plume beneath the region of Mary Byrd Land (MBL).

From field observations to temporally dynamic soil surface roughness retrievals in the U.S. Corn Belt

Soil surface roughness in the U.S. Corn Belt varies outside of the growing season due to rainfall and soil management activities such as tillage. This is not consistent with the assumption that roughness is a static parameter in the Soil Moisture Active Passive (SMAP) soil moisture retrieval algorithm. SMAPVEX16-IA, an extensive field campaign focused on calibration of SMAP retrievals in croplands, occurred during a period when roughness is theoretically at a minima. Satellite-scale measurements of rms height and correlation length collected via pinboard, gridboard, and lidar methodologies resulted in a ensemble of model roughness coefficients that, at h = [0.13, 0.97], is significantly rougher than the original SMAP assumption in croplands of h = 0.108. Comparing simulated brightness temperatures using the ensemble h to SMAP observations resulted in a best-fit angular sensitivity coefficient of N=−2 for both horizontal and vertical polarizations. Satellite-scale h is then retrieved for a four-year study period (excluding growing seasons) via the single channel algorithm from SMAP brightness temperatures and in situ observations of soil moisture and temperature. Roughness retrievals are highly variable in the spring as rainfall events decrease h followed by an increase during soil dry-down; h steadily increases in the fall post-harvest as fields are tilled across the network. Retrievals of h are effectively independent of polarization and demonstrate the potential to simultaneously retrieve soil moisture and roughness in the absence of crops. These soil roughness retrievals could provide new information on tillage and other soil management activities.

Soil, Runoff Water Contaminated with Agrochemicals, their Relationship in Fruits (Passiflora ligularis) Oxapampa-Pasco

It was investigated in the district of Oxapampa, a place of high production of granadilla, where it was observed that farmers frequently use pesticides, they are protagonists of contaminating the soil, runoff water and that it is directly related to the quality of the fruit. The objective was to evaluate the relationship of soil and runoff water, in the concentration of heavy metals in fruits of (Passiflora ligularis), in the sectors; del Abra (Ab), Chacos (Ch), Quillazú (Qll), Acuzazú (Ac), Cañera (Ca), San Alberto (SA), Alto Río Pisco (ARP) and Paraíso (Pa). The Non-experimental and Correlative Design was used. The concentration correlation of As, Hg, Cd, Cu and Pb found in samples collected from soil and water from production fields of three groups (ABC) of farmers, as well as their relationship with the contamination of the fruits was determined. Whose results: Soil-Fruit: Determination index R 2 = (0.013 (As), 0.1348(Hg), 0.1189 (Pb), 0.0079 (Cd) and 0.1577 (Cu)). Runoff water- Fruit: R 2 = (0.109 (As), 0.1586 (Hg), 0.0005 (Pb), 0.0197 (Cd) and 0.0065 (Cu)); statistically it indicates that there is no linear correlation. interpreting for each unit in mg/Kg of each heavy metal that takes the independent variable of contaminated soil and water, there is an increase or decrease in the concentration of metals in the fruit, according to values of the angular coefficient in mg/Kg (As, Hg, Pb, Cd and Cu), according to Pearson, significance (α=0.05) was higher, accepting the null hypothesis, rejecting the alternative hypothesis. Conclusion: the concentrations of heavy metals found in the production fields do not statistically influence the concentration of metals in the fruits.

Undersampled single-shell to MSMT fODF reconstruction using CNN-based ODE solver

Background and Objective: Diffusion MRI (dMRI) has been considered one of the most popular non-invasive techniques for studying the human brain’s white matter (WM). dMRI is used to delineate the brain’s microstructure by approximating the WM region’s fiber tracts. The achieved fiber tracts can be utilized to assess mental diseases like Multiple sclerosis, ADHD, Seizures, Intellectual disability, and others. New techniques such as high angular resolution diffusion-weighted imaging (HARDI) have been developed, providing precise fiber directions, and overcoming the limitation of traditional DTI. Unlike Single-shell, Multi-shell HARDI provides tissue fractions for white matter, gray matter, and cerebrospinal fluid, resulting in a Multi-shell Multi-tissue fiber orientation distribution function (MSMT fODF). This MSMT fODF comes up with more precise fiber directions than a Single-shell, which helps to get correct fiber tracts. In addition, various multi-compartment diffusion models, including as CHARMED and NODDI, have been developed to describe the brain tissue microstructural information. This type of model requires multi-shell data to obtain more specific tissue microstructural information. However, a major concern with multi-shell is that it takes a longer scanning time restricting its use in clinical applications. In addition, most of the existing dMRI scanners with low gradient strengths commonly acquire a single b-value (shell) upto b=1000s/mm2 due to SNR (Signal-to-noise ratio) reasons and severe imaging artifacts.Methods: To address this issue, we propose a CNN-based ordinary differential equations solver for the reconstruction of MSMT fODF from under-sampled and fully sampled Single-shell (b=1000s/mm2) dMRI. The proposed architecture consists of CNN-based Adams-Bash-forth and Runge-Kutta modules along with two loss functions, including L1 and total variation.Results: We have shown quantitative results and visualization of fODF, fiber tracts, and structural connectivity for several brain regions on the publicly available HCP dataset. In addition, the obtained angular correlation coefficients for white matter and full brain are high, showing the proposed network’s utility.Finally, we have also demonstrated the effect of noise by adjusting SNR from 5 to 50 and observed the network robustness.Conclusion: We can conclude that our model can accurately predict MSMT fODF from under-sampled or fully sampled Single-shell dMRI volumes.

О сброшенных напряжениях в очагах умеренных и слабых землетрясений: особенности распределения во времени

An analysis has been performed of the change in stress drops over time during the period of foreshock activity of strong earthquakes for two seismically active regions with different geodynamic settings: the Northern Tien Shan and the Southern Kuril Islands. The catalogs of earthquake dynamic parameters, DP (source ones in English publications), in these regions, with a number of events, were used as initial data. The DP catalog for the Northern Tien Shan includes 183 records of source parameters of earthquakes with magnitudes of 2.6–6.0, and the catalog for the Southern Kurils – 264 records. The stress drop values throughout a general sampling were analyzed as well as that in foreshock periods of 500 days length before the strongest earthquakes. For each region 12 such meaningful events have been specified, the magnitudes were М > 5 for the Northern Tien Shan, and М ≥ 6.5 for the Southern Kurils. The median average values of stress drops during 500-day period have been determined. The temporal variations of stress drops have been compared with changes in the b-value parameter (angular coefficient of earthquake recurrence plot) in the same observation periods. The computation of b-value for the case of the Northern Tien Shan involved the catalog data of KNET seismological network (1994–2021, more than 10 000 events), and the catalog of International Seismological Center (ISC, 1964–2000) for the Southern Kurils. In both cases, b-values were determined in 500-day moving interval with one day step. The computation gave the result that the well-known effect of b-value growth before strong earthquakes manifested itself explicitly in the considered regions. It has been established that such increase in b-value is accompanied by a decrease in the averaged stress drop values. The obtained results showed that the monitoring of the stress drop values can be used to identify the non stationary stage of the seismic regime.

Velocity distribution and hydrodynamic drag in turbulent flow

This work aims to study the vertical velocity distribution in the near-wall layer of a pipe, channel, and boundary layer of a flat plate because these issues are of great practical and theoretical importance. Until now, engineering calculations of turbulent flows have been based on empirical formulas derived in the last century. The theory of turbulent fluid motion has not been completed, and the issues of velocity distribution and hydraulic resistance remain open for further study. It is known that velocity distribution in the flow is intricately linked to hydraulic resistance. Therefore, the study’s objectives also include determining the position of the point of maximum turbulent tangential stresses and comparing the change in tangential stresses with the logarithmic velocity profile. Based on calculation and analytical methods, we have researched the distribution of the turbulent component of the tangential stress along the depth of the flow. Derived an expression determining the position of the maximum point of the turbulent component of the tangential stress for smooth tubes. The contribution of the viscous component of the tangential stress at different points along the flow depth has been evaluated. The calculation results determining the position of the maximum point of the turbulent component of the tangential stress were compared with experimental data on velocity distribution in the flow. With the decrease of the hydraulic resistance coefficient, the point of maximum turbulent tangential stresses shifts towards the solid flow boundary. Based on the results of comparing the maximum turbulent tangential stresses with the total tangential stress, we can conclude that the contribution of the viscous component of the tangential stress to the total amount of friction and its influence on velocity distribution is significant. The angular coefficient of the velocity profile for the flow core is determined.

FRACTURE OF 30CRMNSIA STEEL UNDER MIXED LOADING MODES

Tests were conducted on notched specimens made of 30CrMnSiA steel in loading mode I with the fracture surface perpendicular to the loading direction (90°) and in mode II with shear angles of 45° and 15°. Shear loading was performed using Richard’s grips that allow for a transition from pure mode I to pure mode II by varying the angle of the notch in relation to the direction of the tensile load. Using digital image correlation, the acoustic emission (AE) signals and the strain field were measured during testing, and the damage and microhardness of the polished side face of the specimens were evaluated after failure. The macro- and microscopic research of fracture surfaces revealed that an increase in the shear component during tension leads to changes in the mechanical and acoustic properties and the ductile-to-brittle-transition temperature. This is evidenced by a change of the fracture surface morphology from ductile to brittle at 45° loading direction, accompanied by a change in all estimated acoustic parameters (the total number of events, the angular coefficient of the cumulative distribution of acoustic signals by amplitude-b-value, and the activity of AE signals). An increase in the shear component also leads to a nonlinear dependence of the damage parameters on the load application angle, such as the relative microcrack area S*, average microcrack length lav, and microcrack inclination angle with respect to the loading axis, which correlate with the change in the principal strains estimated by digital image correlation.

Hydrodynamic coefficients of the DARPA SUBOFF AFF-8 in rotating arm maneuver - Part Ⅱ: Test results and discussion

The study of submarine maneuverability is an important part in the overall design of submarines. The goal of this investigation is to study the hydrodynamic coefficients of SUBOFF AFF-8 in rotating arm maneuver. This paper consists of two parts, which deal with the test technology and test results, respectively. Part Ⅱ of this paper presents the angular velocity-dependent derivatives and spatial coupling coefficients of SUBOFF AFF-8 and investigates the forces and moments in steady turn. The forces and moments of SUBOFF AFF-8 are investigated and the hydrodynamic coefficients of SUBOFF AFF-8 are fitted. The results show the coefficients with r in the lower corner represent the linearity of hydrodynamic forces. In order to get more accurate nonlinear coefficients and coupling coefficients, the drift angle should not be too small in the rotating arm test. When SUBOFF AFF-8 has both drift angle and attack angle, the nonlinear degree of rotation increases sharply, which will bring great difficulties to the measurement of forces and moments.

"CATCH" Study: Correct Antibiotic Therapy in Continuous Hemofiltration in the Critically Ill in Continuous Renal Replacement Therapy: A Prospective Observational Study.

The proper posology of antibiotics in the critically ill in CRRT is difficult to assess. We therefore performed a prospective observational cohort study to make clear hints in this topic. Our results reveal a high Sieving Coefficient for all antibiotics, equal to or higher than those described in previous papers. CVVH clearance in relation to total body clearance was significant, (i.e., >than 25% for all classes). A strong correlation between the antibiotic concentrations obtained in plasma and ultrafiltrate was found both at the peak and in the valley, with the determination of two equations that allow a new method for calculating the amount of antibiotic lost in CVVH both for trough levels and peak. Based on the results of our study and considering the limitations we believe that we can extrapolate the following final considerations: (1) it is likely to carry out a loading dose for the main antibiotics (2) subsequent administrations must take into account the daily loss identified by the linear regression equation. This angular coefficient gives the idea that the average daily loss of given antibiotic is about 25%; this implies that on the basis of the linear regression equation that correlates ultrafiltered/plasma antibiotic concentration, the dosage should be increased by 25% every day, while still ensuring a daily plasma TDM of the drug.

Hydrodynamic coefficients of the DARPA SUBOFF AFF-8 in rotating arm maneuver: Part I: Test technology and validation

The study of submarine maneuverability is an important part in the overall design of submarines. The goal of this investigation is to study the hydrodynamic coefficients of SUBOFF AFF-8 in rotating arm maneuver. This paper consists of two parts, which deal with the test technology and test results, respectively. In Part I, the measuring and testing technique of the rotating arm test in rotating arm basin of Zhejiang University (ZJU) is presented. The connection between the model and the trailer is completed through a cylindrical strut. A steel base is pre-installed inside the model to connect one end of the strut. The detailed calibration of the six-component balance is presented. The linear hydrodynamic coefficients on the horizontal and vertical plane are obtained and compared with the results of DTRC. The results show that the ZJU test values is reliable. The difference between DTRC and ZJU is within 10%. Some technical details about the rotating arm test are discussed in the conclusion. Part Ⅱ of this paper presents the angular velocity-dependent derivatives and spatial coupling coefficients of SUBOFF AFF-8 and investigates the forces and moments in steady turn.

Instantaneous effect of real-time avatar visual feedback on interlimb coordination during walking post-stroke

BackgroundGait asymmetry, which is common after stroke, is typically characterized using spatiotemporal parameters of gait that do not consider the aspect of movement coordination. In this manuscript, we examined whether an avatar-based feedback provided as a single-session intervention to improve gait symmetry also improved inter-limb coordination among people with stroke and we examined the relationship between changes in coordination and step length symmetry. MethodsTwelve stroke participants walked on a self-paced treadmill with and without a self-avatar that replicated their locomotor movements in real time. Continuous relative phase and angular coefficient of correspondence calculated using bilateral sagittal hip movements were used to quantify temporal and spatial interlimb coordination, respectively. Spatial gait symmetry, previously shown to improve with the avatar feedback, was quantified using step length ratio between both limbs, with the largest value as numerator. FindingsParticipants who improved their spatial symmetry during avatar exposure also improved their temporal coordination, while spatial coordination remained unchanged. Overall, improvements in spatial symmetry correlated positively with improvements in temporal coordination. The non-paretic hip and paretic ankle angle excursion in the sagittal plane also significantly increased during avatar exposure. InterpretationImprovements in gait symmetry may be explained by changes in interlimb coordination. Current data and existing literature further suggest that such improvements are largely driven by adaptations in non-paretic leg movements, notably at the hip. By providing real-time information on walking movements not affordable in other ways, avatar-based feedback shows great potential to improve gait symmetry and interlimb coordination post-stroke.

Multipole Mixing Ratios of Gamma Rays From Ge 70 32 (p,nγ) As 70 33 Reaction Using the Constant Statistical Tensor Method (CST)

The δ-Multipole mixing ratios of  -transitions from levels of 70As populated in the Ge 70 32 (p,nγ) As 70 33 reaction are calculated by using the constant statistical tensor method (CST). This method has been used in other works [1-5] but only with pure transitions orwith transitions that can be considered as pure transitions. In our work, we used this method for mixed gamma -transitions in addition to pure gmma - transitions. The experimental angular distribution coefficients (a2) was used from previous work [6] in order to calculet δ-values.

Fock Expansion for Two-Electron Atoms: High-Order Angular Coefficients

The Fock expansion, which describes the properties of two-electron atoms near the nucleus, is studied. The angular Fock coefficients ψk,p(α,θ) with the maximum possible value of subscript p are calculated on examples of the coefficients with 5≤k≤10. The presented technique makes it possible to calculate such angular coefficients for any arbitrarily large k. The mentioned coefficients being leading in the logarithmic power series representing the Fock expansion, they may be indispensable for the development of simple methods for calculating the helium-like electronic structure. The theoretical results obtained are verified by other suitable methods. The Wolfram Mathematica is used extensively.

A Program Library for Computing Pure Spin–Angular Coefficients for One- and Two-Particle Operators in Relativistic Atomic Theory

A program library for computing pure spin-angular coefficients for any one- and scalar two-particle operators is presented. The method used is based on the combination of the second quantization and quasi-spin techniques with the angular momentum theory and the method of irreducible tensorial sets. A relativistic approach is assumed. This program library is integrated in the General Relativistic Atomic Structure Package but it can be implemented in other program packages, too.

Oat productivity by root and foliar nitrogen uptake in cropping systems

Urea is the standard source of nitrogen for plants, yet it is very unstable, causing losses and environmental pollution. The objective of this study is to validate the technology of spraying liquid source N-Top® of nitrogen for foliar uptake, considering the main oat crops systems in southern Brazil under different agricultural year conditions. The study was developed in 2016, 2017, and 2018, in the city of Augusto Pestana, RS, Brazil, in system soybean/oat and maize/oat. In each system, two experiments were conducted, one for quantifying the biomass rate and the other for the estimation of grain yield. In the four experiments, the design of the randomized block was used with four repetitions in factorial 2×4, for 2 nitrogen sources (liquid and urea) with 4 doses of the nutrient (0, 30, 60, and 120 kg ha-1), respectively. The urea source with 45% of nitrogen for root absorption and the liquid with 28% (N-Top®), via foliar absorption, were applied at the phenological stage of the fourth expanded leaf. In corn/oat system, increasing the dose of nitrogen from urea and liquid sources promotes linear behavior in the expression of grain yield, with similar values of angular coefficient. In the soybean/oat system in the average of the agricultural years, the dose of 78 kg ha-1 of nitrogen, promotes grain yield around 3000 kg ha-1, regardless of the nutrient source. N-top® liquid source nitrogen validation is confirmed, however the acquisition cost may make the recommendation unfeasible

Development of a new [formula omitted]–[formula omitted] angular correlation analysis method using a symmetric ring of clover detectors

A new method for γ–γ angular correlation analysis using a symmetric ring of HPGe clover detectors is presented. Pairwise combinations of individual crystals are grouped based on the geometric properties of the spectrometer, constrained by a single variable parameterization based on symmetry considerations. The corresponding effective interaction angles between crystal pairs, as well as the attenuation coefficients are extracted directly from the measured experimental data. Angular correlation coefficients, parameter uncertainties and parameter co-variances are derived using a Monte-Carlo approach, considering all sources of statistical uncertainty. The general applicability of this approach is demonstrated by reproducing known multipole mixing ratios in 177Hf, 152Gd and 116Sn, populated by either β-decay or (n, γ)-reactions, measured at the Institut Laue-Langevin, using the EXILL&FATIMA spectrometer and different configurations of the FIPPS instrument. The derived mixing ratios are in excellent agreement with adopted literature values with comparable or better precision.

Training and validation of a knowledge-based dose-volume histogram predictive model in the optimisation of intensity-modulated proton and volumetric modulated arc photon plans for pleural mesothelioma patients

BackgroundTo investigate the performance of a narrow-scope knowledge-based RapidPlan (RP) model for optimisation of intensity-modulated proton therapy (IMPT) and volumetric modulated arc therapy (VMAT) plans applied to patients with pleural mesothelioma. Second, estimate the potential benefit of IMPT versus VMAT for this class of patients.MethodsA cohort of 82 patients was retrospectively selected; 60 were used to "train" a dose-volume histogram predictive model; the remaining 22 provided independent validation. The performance of the RP models was benchmarked, comparing predicted versus achieved mean and near-to-maximum dose for all organs at risk (OARs) in the training set and by quantitative assessment of some dose-volume metrics in the comparison of the validation RP-based data versus the manually optimised training datasets. Treatment plans were designed for a prescription dose of 44 Gy in 22 fractions (proton doses account for a fixed relative biological effectiveness RBE = 1.1).ResultsTraining and validation RP-based plans resulted dosimetrically similar for both VMAT and IMPT groups, and the clinical planning aims were met for all structures. The IMPT plans outperformed the VMAT ones for all OARs for the contra-lateral and the mean and low dose regions for the ipsilateral OARs. Concerning the prediction performance of the RP models, the linear regression for the near-to-maximum dose resulted in Dachieved = 1.03Dpredicted + 0.58 and Dachieved = 1.02Dpredicted + 1.46 for VMAT and IMPT, respectively. For the mean dose it resulted: Dachieved = 0.99Dpredicted + 0.34 and Dachieved = 1.05Dpredicted + 0.27 respectively. In both cases, the linear correlation between prediction and achievement is granted with an angular coefficient deviating from unity for less than 5%. Concerning the dosimetric comparison between manual plans in the training cohort and RP-based plans in the validation cohort, no clinical differences were observed for the target volumes in both the VMAT and IMPT groups. Similar consistency was observed for the dose-volume metrics analysed for the OAR. This proves the possibility of achieving the same quality of plans with manual procedures (the training set) or with automated RP-based methods (the validation set).ConclusionTwo models were trained and validated for VMAT and IMPT plans for pleural mesothelioma. The RP model performance resulted satisfactory as measured by the agreement between predicted and achieved (after full optimisation) dose-volume metrics. The IMPT plans outperformed the VMAT plans for all the OARs (with different intensities for contra- or ipsilateral structures). RP-based planning enabled the automation of part of the optimisation and the harmonisation of the dose-volume results between training and validation. The IMPT data showed a systematic significant dosimetric advantage over VMAT. In general, using an RP-based approach can simplify the optimisation workflow in these complex treatment indications without impacting the quality of plans.

Angular coefficients in hbox {W}+hbox {j} production at the LHC with high precision

The extraction of the W-boson mass, a fundamental parameter of the Standard Model, from hadron-hadron collision requires precise theory predictions. In this regard, angular coefficients are crucial to model the dynamics of W-boson production. In this work, we provide, for the first time, angular coefficients at NNLO QCD + NLO EW accuracy for finite transverse momentum W-boson at the LHC. The corrections can reach up to 10% in certain regions of phase space. They are accompanied by a significant reduction of the scale uncertainty. This work should, besides providing reference values for theory-data comparison, provide state-of-the-art theory input for W-boson mass measurements.
