description: The procedure to improve the convergence in transverse momentum space of the NLL BFKL kernel using a w-shift is revisited. An accurate approximation to this shift only depending on transverse momenta is presented. This approximation is based on a Bessel function of the first kind with argument depending on the strong coupling and a double logarithm of the ratio of transverse scales. A comparison between different renormalization schemes is also included.

description: We present spatially resolved VLT/SINFONI spectroscopy with adaptive optics of type-2 active galactic nuclei (AGN) from the SINFONI Survey for Unveiling the Physics and Effect of Radiative feedback (SUPER), which targeted X-ray bright ($L_{2-10 keV}\gtrsim10^{42}$ erg s$^{-1}$) AGN at Cosmic Noon ($z\sim2$). Our analysis of the rest-frame optical spectra unveils ionised outflows in all seven examined targets, as traced via [OIII]$λ$5007 line emission, moving at $v\gtrsim600$ km s$^{-1}$. In six objects these outflows are clearly spatially resolved and extend on 2-4 kpc scales, whereas marginally resolved in the remaining one. Interestingly, these SUPER type-2 AGN are all heavily obscured sources ($N_{H}\gtrsim10^{23}$ cm$^{-2}$) and host faster ionised outflows than their type-1 counterparts within the same range of bolometric luminosity ($L_{bol} \sim 10^{44.8-46.5}$ erg s$^{-1}$). SUPER has hence provided observational evidence that the type-1/type-2 dichotomy at $z\sim2$ might not be driven simply by projection effects, but might reflect two distinct obscuring life stages of active galaxies, as predicted by evolutionary models. Within this picture, SUPER type-2 AGN might be undergoing the 'blow-out' phase, where the large amount of obscuring material efficiently accelerates large-scale outflows via radiation pressure on dust, eventually unveiling the central active nucleus and signal the start of the bright, unobscured type-1 AGN phase. Moreover, the overall population of ionised outflows detected in SUPER has velocities comparable with the escape speed of their dark matter halos, and in general high enough to reach 30-50 kpc distances from the centre. These outflows are hence likely to sweep away the gas (at least) out of the baryonic disk and/or to heat the host gas reservoir, thus reducing and possibly quenching star formation.

description: It is often claimed that analysis with infinitesimals requires more substantial use of the Axiom of Choice than traditional elementary analysis. The claim is based on the observation that the hyperreals entail the existence of nonprincipal ultrafilters over N, a strong version of the Axiom of Choice, while the real numbers can be constructed in ZF. The axiomatic approach to nonstandard methods refutes this objection. We formulate a theory SPOT in the st-$\in$-language which suffices to carry out infinitesimal arguments, and prove that SPOT is a conservative extension of ZF. Thus the methods of Calculus with infinitesimals are just as effective as those of traditional Calculus. The conclusion extends to large parts of ordinary mathematics and beyond. We also develop a stronger axiomatic system SCOT, conservative over ZF+ADC, which is suitable for handling such features as an infinitesimal approach to the Lebesgue measure. Proofs of the conservativity results combine and extend the methods of forcing developed by Enayat and Spector.

description: Рассматривается смысловое наполнение важной для модернизма мифологемы души у двух крупнейших его представителей — А.А.Блока и И.Ф.Анненского. Исследование проводится на материале статьи Блока «Душа писателя» (1909) и стихотворения в прозе Анненского «Моя душа» (1908). Исходная ситуация для обоих поэтов общая — замкнутость персональной души писателя. Между тем при внешнем сходстве предмета осмысления в публикации выявляется прежде всего различия в понимании «души» творца и способа преодоления замкнутости персональной писательской души двумя писателями. Анализ показал, что блоковская трактовка мифологемы души соотнесена с его основным авторским мифом о Мировой Душе, в слиянии с которой ему видится драмы индивидуализма. Лишь улавливая ее космические ритмы, душа писателя, по Блоку, способна обрести подлинный «путь». В отличие от Блока мифологему души Анненский рассматривает в системе нравственно-психологических координат, что подтверждается выделенным мотивом страдания души. Разрешение муки и внутренней, и внешней для Анненского возможно не метафизически (как для Блока), а лишь эстетически, творчески.
How do the successive buckling events affect a galaxy bar and stellar disk? Potential Observable Signatures For Spotting the Buckling Action -- I

description: Until now, observations have caught up only a handful of galaxies in ongoing buckling action. Interestingly, N-body simulations over the past several decades show that almost every bar buckles or vertically thickens as soon as it reaches its peak strength during its evolution and leads to box$/$ peanut$/$ x (BPX) shapes. In order to understand the effect of multiple buckling events on the observable properties of galactic bar and disk, we perform an N-body simulation of a Milky Way-type disk. The axisymmetric galaxy disk forms a bar within a Gyr of its evolution and the bar undergoes two successive buckling events. We report that the time spans of these two buckling events are 220 Myr and 1 Gyr which have almost similar strengths of the bending modes. As a result of these two buckling events, the sizes of BPX shapes are around 5.8 kpc and 8.6 kpc which are around two-thirds of the bar length at the end of each buckling event. We find that the first buckling occurs at a smaller scale (radius less than 3 kpc) with a shorter time span affecting the larger length scales of the disk which is quantified in terms of changes in $m$ =2 and $m$ = 4 Fourier modes. While the second buckling occurs at larger scales (radius of around 6 kpc) affecting the inner disk the most. Finally, we provide observable kinematic signatures (for example quadrupolar patterns of the line-of-sight velocities) which can potentially differentiate the successive buckling events.

description: Urban mobility needs alternative sustainable travel modes to keep our pandemic cities in motion. Ride-pooling, where a single vehicle is shared by more than one traveller, is not only appealing for mobility platforms and their travellers, but also for promoting the sustainability of urban mobility systems. Yet, the potential of ride-pooling rides to serve as a safe and effective alternative given the personal and public health risks considerations associated with the COVID-19 pandemic is hitherto unknown. To answer this, we combine epidemiological and behavioural shareability models to examine spreading among ride-pooling travellers, with an application for Amsterdam. Findings are at first sight devastating, with only few initially infected travellers needed to spread the virus to hundreds of ride-pooling users. Without intervention, ride-pooling system may substantially contribute to virus spreading. Notwithstanding, we identify an effective control measure allowing to halt the spreading before the outbreaks (at 50 instead of 800 infections) without sacrificing the efficiency achieved by pooling. Fixed matches among co-travellers disconnect the otherwise dense contact network, encapsulating the virus in small communities and preventing the outbreaks.

description: We report results from {\it XMM-Newton} observations of thirteen X-ray bright BL Lacertae objects, selected from the {\it Einstein} Slew Survey sample. The survey was designed to look for evidence of departures of the X-ray spectra from a simple power law shape (i.e., curvature and/or line features), and to find objects worthy of deeper study. Our data are generally well fit by power-law models, with three cases having hard ($Γ<2; dN/dE \propto E^{-Γ}$) spectra that indicate synchrotron peaks at $E \gsim 5$ keV. Previous data had suggested a presence of absorption features in the X-ray spectra of some BL Lacs. In contrast, none of these spectra show convincing examples of line features, either in absorption or emission, suggesting that such features are rare amongst BL Lacs, or, more likely, artifacts caused by instrumental effects. We find significant evidence for intrinsic curvature (steepening by $dΓ/ d({\rm log} E) = 0.4 \pm 0.15$) in fourteen of the seventeen X-ray spectra. This cannot be explained satisfactorily via excess absorption, since the curvature is essentially constant from $0.5-6$ keV, an observation which is inconsistent with the modest amounts of absorption that would be required. We use the {\it XMM-Newton} Optical Monitor data with concurrent radio monitoring to derive broadband spectral energy distributions and peak frequency estimates. From these we examine models of synchrotron emission and model the spectral curvature we see as the result of episodic particle acceleration.

description: Learning from visual data opens the potential to accrue a large range of manipulation behaviors by leveraging human demonstrations without specifying each of them mathematically, but rather through natural task specification. In this paper, we present Learning by Watching (LbW), an algorithmic framework for policy learning through imitation from a single video specifying the task. The key insights of our method are two-fold. First, since the human arms may not have the same morphology as robot arms, our framework learns unsupervised human to robot translation to overcome the morphology mismatch issue. Second, to capture the details in salient regions that are crucial for learning state representations, our model performs unsupervised keypoint detection on the translated robot videos. The detected keypoints form a structured representation that contains semantically meaningful information and can be used directly for computing reward and policy learning. We evaluate the effectiveness of our LbW framework on five robot manipulation tasks, including reaching, pushing, sliding, coffee making, and drawer closing. Extensive experimental evaluations demonstrate that our method performs favorably against the state-of-the-art approaches.

description: In this paper we investigate factorizations of polynomials over the ring of dual quaternions into linear factors. While earlier results assume that the norm polynomial is real ("motion polynomials"), we only require the absence of real polynomial factors in the primal part and factorizability of the norm polynomial over the dual numbers into monic quadratic factors. This obviously necessary condition is also sufficient for existence of factorizations. We present an algorithm to compute factorizations of these polynomials and use it for new constructions of mechanisms which cannot be obtained by existing factorization algorithms for motion polynomials. While they produce mechanisms with rotational or translational joints, our approach yields mechanisms consisting of "vertical Darboux joints". They exhibit mechanical deficiencies so that we explore ways to replace them by cylindrical joints while keeping the overall mechanism sufficiently constrained.

description: Neutral atomic gas (HI) effectively traces galactic dynamics across mid to large galactocentric radii. However, its limitations in observing small-scale changes within the central few kiloparsecs, coupled with the often observed HI deficit in galactic centers, necessitates using molecular gas emission as a preferred tracer in these regions. Understanding the dynamics of both neutral atomic and molecular gas is crucial for a more complete understanding of how galaxies evolve, funnel gas from the outer disk into their central parts, and eventually form stars. In this work we aim to quantify the dynamics of both, the neutral atomic and molecular gas, in the nearby spiral galaxies NGC 1512, NGC 4535, and NGC 7496 using new MeerKAT-HI observations together with ALMA CO (2-1) observations from the PHANGS collaboration. We use the analysis tool 3D-Barolo to fit tilted ring models to the HI and CO observations. A combined approach of using the HI to constrain the true disk orientation parameters before applying these to the CO datasets is tested. This paper sets expectations for the results of the upcoming high-resolution HI coverage of many galaxies in the PHANGS-ALMA sample using MeerKAT or VLA, to establish a robust methodology for characterizing galaxy orientations and deriving dynamics from combining new HI with existing CO data.

description: Anomalous features of the proximity effect specific to diffusive normal metal / triplet superconductor (DN/TS) junctions are studied within the quasiclassical Green's function formalism. The pair amplitude $f_{N}$ as a function of energy $ε$ in DN, satisfies an anomalous relation, $% f_{N}(ε)=-f^{*}_{N}(-ε)$, contrary to that in singlet superconductor junctions case where $f_{N}(ε)=f^{*}_{N}(-% ε)$. Such an unusual $ε$ dependence is responsible for a zero energy peak in the local density of states and is a source of an anomalous penetration of the applied magnetic field into DN. % Our results are relevant to Sr$_{2}$RuO$_{4}$, which is considered to have a $p_{x}+ip_{y}$-wave symmetry.

description: Many software development problems can be addressed by program analysis tools, which traditionally are based on precise, logical reasoning and heuristics to ensure that the tools are practical. Recent work has shown tremendous success through an alternative way of creating developer tools, which we call neural software analysis. The key idea is to train a neural machine learning model on numerous code examples, which, once trained, makes predictions about previously unseen code. In contrast to traditional program analysis, neural software analysis naturally handles fuzzy information, such as coding conventions and natural language embedded in code, without relying on manually encoded heuristics. This article gives an overview of neural software analysis, discusses when to (not) use it, and presents three example analyses. The analyses address challenging software development problems: bug detection, type prediction, and code completion. The resulting tools complement and outperform traditional program analyses, and are used in industrial practice.
Heavy-to-light meson form factors at large recoil

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: Heavy-to-light meson form factors at large recoil can be described using the same techniques as for hard exclusive processes involving only light hadrons. Two competing mechanisms appear in the large-recoil regime, describing so-called ``soft-overlap'' and ``hard-scattering'' components of the form factors. It is shown how existing experimental data from B and D decays constrain the relative size of these components, and how lattice data can be used to study properties such as the energy scaling laws obeyed by the individual components. Symmetry relations between different form factors (F_+, F_0 and F_T), and between different heavy initial-state mesons (B and D), are derived in the combined heavy-quark and large-recoil limits, and are shown to generalize corresponding relations valid at small recoil. Form factor parameterizations that are consistent with the large-recoil limit are discussed.

description: In order to establish the computational equivalence between quantum Turing machines (QTMs) and quantum circuit families (QCFs) using Yao's quantum circuit simulation of QTMs, we previously introduced the class of uniform QCFs based on an infinite set of elementary gates, which has been shown to be computationally equivalent to the polynomial-time QTMs (with appropriate restriction of amplitudes) up to bounded error simulation. This result implies that the complexity class BQP introduced by Bernstein and Vazirani for QTMs equals its counterpart for uniform QCFs. However, the complexity classes ZQP and EQP for QTMs do not appear to equal their counterparts for uniform QCFs. In this paper, we introduce a subclass of uniform QCFs, the finitely generated uniform QCFs, based on finite number of elementary gates and show that the class of finitely generated uniform QCFs is perfectly equivalent to the class of polynomial-time QTMs; they can exactly simulate each other. This naturally implies that BQP as well as ZQP and EQP equal the corresponding complexity classes of the finitely generated uniform QCFs.

description: Blind or no-reference video quality assessment of user-generated content (UGC) has become a trending, challenging, heretofore unsolved problem. Accurate and efficient video quality predictors suitable for this content are thus in great demand to achieve more intelligent analysis and processing of UGC videos. Previous studies have shown that natural scene statistics and deep learning features are both sufficient to capture spatial distortions, which contribute to a significant aspect of UGC video quality issues. However, these models are either incapable or inefficient for predicting the quality of complex and diverse UGC videos in practical applications. Here we introduce an effective and efficient video quality model for UGC content, which we dub the Rapid and Accurate Video Quality Evaluator (RAPIQUE), which we show performs comparably to state-of-the-art (SOTA) models but with orders-of-magnitude faster runtime. RAPIQUE combines and leverages the advantages of both quality-aware scene statistics features and semantics-aware deep convolutional features, allowing us to design the first general and efficient spatial and temporal (space-time) bandpass statistics model for video quality modeling. Our experimental results on recent large-scale UGC video quality databases show that RAPIQUE delivers top performances on all the datasets at a considerably lower computational expense. We hope this work promotes and inspires further efforts towards practical modeling of video quality problems for potential real-time and low-latency applications. To promote public usage, an implementation of RAPIQUE has been made freely available online: \url{https://github.com/vztu/RAPIQUE}.

description: This paper reports the results of economic analysis of the effects of floor space and feeder space on broiler chicken growth rates. First, liveweightffeed conversion rates are described and a function fitted. Use of conversion efficiency functions for determining optimal space inputs in the production process would be appropriate where feed cost considerations are dominant. Second, use of more orthodox response surface analysis permits specific consideration of marginal productivities of floor and feeder space inputs. Optimal input levels (i.e., stocking rates and feeder space allocations) and profit margins are developed parametrically for a range of input costs and liveweight prices.

description: In this paper, we propose Varying Effects Regression with Graph Estimation (VERGE), a novel Bayesian method for feature selection in regression. Our model has key aspects that allow it to leverage the complex structure of data sets arising from genomics or imaging studies. We distinguish between the predictors, which are the features utilized in the outcome prediction model, and the subject-level covariates, which modulate the effects of the predictors on the outcome. We construct a varying coefficients modeling framework where we infer a network among the predictor variables and utilize this network information to encourage the selection of related predictors. We employ variable selection spike-and-slab priors that enable the selection of both network-linked predictor variables and covariates that modify the predictor effects. We demonstrate through simulation studies that our method outperforms existing alternative methods in terms of both feature selection and predictive accuracy. We illustrate VERGE with an application to characterizing the influence of gut microbiome features on obesity, where we identify a set of microbial taxa and their ecological dependence relations. We allow subject-level covariates including sex and dietary intake variables to modify the coefficients of the microbiome predictors, providing additional insight into the interplay between these factors.
A Note on Supply Responses in the Adelaide Whole Milk Zone

description: In the Adelaide whole milk supply area, licensed dairymen are encouraged by higher bonus payments to maintain production during the summer and autumn months. High bonus payments in the late 1950s encouraged dairymen to increase output, but by 1960-61 the Adelaide whole-milk market was substantially oversupplied, principally as a result of marked increases in productivity on dairy holdings. Excess supplies have resulted in declining butterfat prices, but productivity gains have been sufficient to maintain rising farm incomes for the more specialised producers remaining in the whole-milk industry.
Explosive Nucleosynthesis in GRB Jets Accompanied by Hypernovae

description: Two-dimensional hydrodynamic simulations are performed to investigate explosive nucleosynthesis in a collapsar using the model of MacFadyen and Woosley (1999). It is shown that 56Ni is not produced in the jet of the collapsar sufficiently to explain the observed amount of a hypernova when the duration of the explosion is \sim 10 sec, which is considered to be the typical timescale of explosion in the collapsar model. Even though a considerable amount of 56Ni is synthesized if all explosion energy is deposited initially, the opening angles of the jets become too wide to realize highly relativistic outflows and gamma-ray bursts in such a case. From these results, it is concluded that the origin of 56Ni in hypernovae associated with GRBs is not the explosive nucleosynthesis in the jet. We consider that the idea that the origin is the explosive nucleosynthesis in the accretion disk is more promising. We also show that the explosion becomes bi-polar naturally due to the effect of the deformed progenitor. This fact suggests that the 56Ni synthesized in the accretion disk and conveyed as outflows are blown along to the rotation axis, which will explain the line features of SN 1998bw and double peaked line features of SN 2003jd. Some fraction of the gamma-ray lines from 56Ni decays in the jet will appear without losing their energies because the jet becomes optically thin before a considerable amount of 56Ni decays as long as the jet is a relativistic flow. We show that abundance of nuclei whose mass number \sim 40 in the ejecta depends sensitively on the energy deposition rate. So it may be determined by observations of chemical composition in metal poor stars which model is the proper one as a model of a gamma-ray burst accompanied by a hypernova.

description: Between 1964 and 1966 a very detailed study of food distribution in the United States was undertaken by the National Commission on Food Marketing. In this article an attempt is made to set out the main findings of the Commission and to evaluate them. This study was undertaken primarily to examine whether the growing margin between the prices consumers pay and the prices farmers receive in the United States was justified and if not how it could be reduced. The Commission concluded that the growth in this margin was, by and large, justified; that food processors and retailers were technically progressive and earning mostly profits which were comparable with those in other sectors of the economy. A majority of the Commission was critical of excessive advertising expenditures in the marketing and distribution of food. The Commission assembled a sizable staff to provide a detailed picture of present trends; in addition they undertook some useful analyses of the profitability of different sections of the food marketing and retailing industries and of the factors which affect such profitability.

description: In studying temperature fluctuations in the cosmic microwave background Weinberg has noted that some ease of calculation and insight can be achieved by looking at the structure of the perturbed light cone on which the perturbed photons propagate. In his approach Weinberg worked in a specific gauge and specialized to fluctuations around the standard Robertson-Walker cosmological model with vanishing spatial three-curvature. In this paper we generalize this analysis by providing a gauge invariant treatment in which no choice of gauge is made, and by considering geometries with non-vanishing spatial three-curvature. By using the scalar, vector, tensor fluctuation basis we find that the relevant gauge invariant combinations that appear in the light cone temperature fluctuations have no explicit dependence on the spatial curvature even if the spatial curvature of the background geometry is nonvanishing. We find that a not previously considered, albeit not too consequential, temperature fluctuation at the observer has to be included in order to enforce gauge invariance. As well as working with comoving time we also work with conformal time in which a background metric of any given spatial three-curvature can be written as a time-dependent conformal factor (the comoving time expansion radius as written in conformal time) times a static Robertson-Walker geometry of the same spatial three-curvature. For temperature fluctuations on the light cone this conformal factor drops out identically. Thus the gauge invariant combinations that appear in the photon temperature fluctuations have no explicit dependence on either the conformal factor or the spatial three-curvature at all.

Gaining trust advantage for the vaccination certificate platform
Creators: name: Joller, Liina
Publisher: name: Journal of Business Models
Year: 2021

description: Purpose: In the conventional international health and safety policy design the decision makers rarely think in terms of business models. As an example, the yellow paper-based vaccination certificates, initiated by the WHO already in 1969, have not changed very much since then. In 2020, the Covid-19 crisis accelerated innovation, particularly digitalization, in many sectors, and the sense of urgency to have a digital immunisation certificate was voiced by many governments, as well as corporations. The new solution must enable international interoperability, but it is a challenging task because the setup of health registries varies across countries, and also because the common actions have been hindered due to the lack of trust – the trust deficit. Approach: In this article the case is discussed in the platform business model framework, and the role of trust in gaining competitive advantage – the trust advantage – in its fast and widespread adoption is particularly exemplified. The case was written in parallel with the actual development and piloting of the vaccination certificate platform, not ex post, as common in business model literature. Findings: The solution that could be capable of overcoming the privacy and security concerns that have been brought up in the international discourse can be described as a decentralised multi-sided platform, which has a distributed management system. The platform’s standardisation would ease its global uptake, and the strategic partnerships with countries, organisations, and firms that are already considered trustworthy (possess trust credit) will have the opportunity to gain trust advantage. Limitations: This paper is written having the managerial perspective in mind, hence, it does not go deeply into all technical and legal aspects affecting the implementation of the digital vaccination certificate platform.

description: There are a variety of elementary and collective terahertz-frequency excitations in condensed matter whose magnetic field dependence contains significant insight into the states and dynamics of the electrons involved. Often, determining the frequency, temperature, and magnetic field dependence of the optical conductivity tensor, especially in high magnetic fields, can clarify the microscopic physics behind complex many-body behaviors of solids. While there are advanced terahertz spectroscopy techniques as well as high magnetic field generation techniques available, combination of the two has only been realized relatively recently. Here, we review the current state of terahertz time-domain spectroscopy experiments in high magnetic fields. We start with an overview of time-domain terahertz detection schemes with a special focus on how they have been incorporated into optically accessible high-field magnets. Advantages and disadvantages of different types of magnets in performing terahertz time-domain spectroscopy experiments are also discussed. Finally, we highlight some of the new fascinating physical phenomena that have been revealed by terahertz time-domain spectroscopy in high magnetic fields.

description: An inventory model is used to determine least-cost fodder reserves for sheep in the Hamilton area of Victoria. Unlike earlier studies a grazing model is used to generate feeding requirements and thus allows for the gradual onset of drought and the associated rise in feed prices. Compared with studies based on probabilities of effective rainfall, the approach used measures more accurately the way in which drought incidence is affected by the seasonal pattern of pasture production in relation to animal requirements. The grazing model facilitates a study of the relative severity of drought at a range of stocking rates and a number of probability distributions are identified. The refinements achieved by using a grazing model also allow a more realistic treatment of penalty costs than the usual prescription of a constant drought price for fodder. Furthermore it allows for the determination of least-cost fodder reserves for a range of stocking rates, and thus a comparison between stocking rates is possible because allowances can be made for the effect of different timing and level of feeding on feed costs. The sensitivity of the least cost reserve to changes in acquisition cost and rate or interest is examined for various stocking rates.
The developmental course of children’s free-labeling responses to facial expressions

Publisher: name: University of British Columbia

description: The current study investigated the developmental course of how young children label various facial expressions of emotion. 160 children (2 to 5 years) freely produced labels for six prototypical facial expressions of emotion and six animals. Even 2-year-olds were able to correctly label 5 of 6 animals, but the proportion of correct specific emotion category responses for this age group was < .30 for each of the six facial expressions. The 5-year-olds' proportion of correct specific emotion category labels was at ceiling for the happy and angry faces, but significantly lower for each of the other four facial expressions, and at floor level for the disgust face. The type of errors in labeling facial expressions changed with age: when incorrect, the youngest children produced any emotion label; older children produced labels of the correct valence; and the majority of the 5-year-olds' responses were of the correct specific emotion category. These results indicate that the free-labeling task per se is not too difficult even for 2-year-olds, but that children's use of emotion terms is not initially linked to facial expressions. Thus, the children's production of emotion terms far exceeded their proportion of correct specific emotion category labels. With age, children's implicit definition of emotion terms develops to include the associated facial expression, though this process is not complete for all expressions before the age of 6 years.
Connecting the radio AGN life cycle to feedback: Ionised gas is more disturbed in young radio AGN

description: In the host galaxies of radio AGN, kinematically disturbed gas due to jet-driven feedback is a widely observed phenomenon. Simulations predict that the impact of jets on the surrounding gas changes as they grow. Useful insights into this phenomenon can be obtained by characterising radio AGN into different evolutionary stages and studying their impact on gas kinematics. We present a systematic study of the [OIII] gas kinematics for a sample of 5720 radio AGN up to $z\sim0.8$ with a large 1.4 GHz luminosity range of $\approx10^{22.5}-10^{28}$W/Hz, and 1693 [OIII] detections. Taking advantage of the wide frequency coverage of LOFAR and VLA surveys from $144-3000$MHz, we determine the radio spectral shapes, using them to characterise sources into different stages of the radio AGN life cycle. We determine the [OIII] kinematics from SDSS spectra and link it to the life cycle. Our main conclusion is that the [OIII] gas is $\sim$3 times more likely to be disturbed in the peaked spectrum (PS) sources (that represent a young phase of activity) than non-peaked spectrum (NPS) sources (that represent more evolved sources) at $z<0.4$. This changes to a factor of $\sim$2 at $z>0.4$. This shows that on average, the strong impact of jets is limited to the initial stages of the radio AGN life cycle. At later stages, the impact on gas is more gentle. We also determine the dependence of this trend on 1.4GHz and [OIII] luminosities and find that the difference between the two groups increases with 1.4GHz luminosity. Young radio AGN with $L_\mathrm{1.4GHz}>10^{25}$W/Hz have the most extreme impact on [OIII]. Using a stacking analysis, we are further able to trace the changing impact on [OIII] in the high-frequency peaked spectrum (i.e. youngest), low-frequency peaked spectrum ("less young"), and non-peaked spectrum (evolved) radio AGN.
