description: Electroencephalography may be a valuable tool for assessing lexico-semantic processing in conditions where behavioural measures are unreliable. Detecting and quantifying effects in individuals is crucial for clinical applications, but individual-subject analyses are frequently not reported, and are hampered by low signal-to-noise. Multivariate analyses (MVPA) may be more sensitive than traditional approaches, so we asked how robustly they could detect differential neural responses to semantically matched and mismatched word/picture pairs in individuals. With clinical application in mind, we compared data from a research-grade EEG system to concurrently recorded data from the wireless Emotiv EPOC + . In both EEG systems, despite robust group-level effects, we only detected statistically significant processing of lexico-semantic condition in 50% of individuals. Surprisingly, detection rates were similar for MVPA and univariate analyses. MVPA may be advantageous when individual responses are heterogeneous, but in this simple paradigm, lexico-semantic processing could not be reliably detected at the individual level.

description: We investigate in detail the charged Higgs production associated with a $W$ boson at electron-positron colliders within the framework of the Type-I two-Higgs-doublet model (THDM). We calculate the integrated cross section at the LO and analyze the dependence of the cross section on the THDM parameters and the colliding energy in a benchmark scenario of the input parameters of Higgs sector. The numerical results show that the integrated cross section is sensitive to the charged Higgs mass, especially in the vicinity of $m_{H^{\pm}} \simeq 184~ {\rm GeV}$ at a $500~ {\rm GeV}$ $e^+e^-$ collider, and decreases consistently as the increment of $\tanβ$ in the low $\tanβ$ region. The peak in the colliding energy distribution of the cross section arises from the resonance of loop integrals and its position moves towards low colliding energy as the increment of $m_{H^{\pm}}$. We also study the two-loop NLO QCD corrections to both the integrated cross section and the angular distribution of the charged Higgs boson, and find that the QCD relative correction is also sensitive to the charged Higgs mass and strongly depends on the final-state phase space. For $\tanβ= 2$, the QCD relative correction at a $500~ {\rm GeV}$ $e^+e^-$ collider varies in the range of $[-10\%,\, 11\%]$ as $m_{H^{\pm}}$ increases from $150$ to $400~ {\rm GeV}$.

description: We study families of polynomial dynamical systems inspired by biochemical reaction networks. We focus on complex balanced mass-action systems, which have also been called toric. They are known or conjectured to enjoy very strong dynamical properties, such as existence and uniqueness of positive steady states, local and global stability, persistence, and permanence. We consider the class of disguised toric dynamical systems, which contains toric dynamical systems, and to which all dynamical properties mentioned above extend naturally. By means of (real) algebraic geometry we show that some reaction networks have an empty toric locus or a toric locus of Lebesgue measure zero in parameter space, while their disguised toric locus is of positive measure. We also propose some algorithms one can use to detect the disguised toric locus.

description: Secondary contacts can play a major role in the evolutionary histories of species. Various taxa diverge in allopatry and later on come into secondary contact during range expansions. When they meet, their interactions and the extent of gene flow depend on the level of their ecological differentiation and the strength of their reproductive isolation. In this study, we present the multilocus phylogeography of two cryptic whiskered bat species, Myotis mystacinus and M. davidii, with a particular focus on their putative sympatric zone. Our findings suggest that M. mystacinus and M. davidii evolved in allopatry and came into secondary contact during range expansions. Individuals in the area of secondary contact, in Anatolia and the Balkans, have discordant population assignments based on the mitochondrial and the nuclear datasets. These observed patterns suggest that the local M. mystacinus populations hybridized with expanding M. davidii populations, which resulted in mitochondrial introgression from the former. In the introgression area, M. mystacinus individuals with concordant nuclear and mitochondrial genotypes were identified in relatively few locations, suggesting that the indigenous populations might have been largely replaced by invading M. davidii. Changing environmental conditions coupled with ecological competition is the likely reason for this replacement. Our study presents one possible example of a historical population replacement that was captured in phylogeographic patterns.
Theory and Simulations of Compressional and Global Alfven Eigenmode Stability in Spherical Tokamaks

Publisher: name: arXiv
Year: 2020
Subjects: subject: Plasma Physics (physics.plasm-ph)
subject: FOS: Physical sciences

description: Neutral-beam-driven, sub-cyclotron compressional (CAE) and global (GAE) \Alfven eigenmodes are routinely excited in spherical tokamaks such as NSTX(-U) and MAST, have been observed on the conventional aspect ratio tokamak DIII-D, and may be unstable in ITER burning plasmas. Their presence has been experimentally linked to the anomalous flattening of electron temperature profiles at high beam power in NSTX, potentially limiting fusion performance. A detailed understanding of CAE/GAE excitation, therefore, is vital to predicting (and ultimately controlling) their effects on plasma confinement. To this end, hybrid kinetic-MHD simulations are complemented with an analytic study of the linear stability properties of CAEs and GAEs. Perturbative, local analytic theory has been used to derive new instability conditions for CAEs/GAEs driven by realistic neutral beam distributions. A comprehensive set of simulations of NSTX-like plasmas has been performed for a wide range of beam parameters, providing a wealth of information on CAE and GAE stability in spherical tokamaks. Linear simulations show that the excitation of CAEs vs GAEs has a complex dependence on the fast ion injection velocity and geometry, qualitatively described by the analytic theory developed in this thesis. Strong energetic particle modifications of GAEs are found in simulations, indicating the existence of a new type of high frequency energetic particle mode. A cross validation between the theoretical stability bounds, simulation results, and experimental measurements shows favorable agreement for both the unstable CAE and GAE spectra's dependence on fast ion parameters. The analytic results accurately explain the recent experimental discovery of GAE stabilization with small amounts of off-axis beam injection on NSTX-U and suggest new techniques for control of these instabilities in future experiments.

Dopamine trasporter reversal as a pathogenic mechanism for L-dopa induced dyskinesia
Creators: name: Cheng, Christina
Publisher: name: University of British Columbia
Year: 2009

description: L-dopa remains the most effective drug for improving motor symptoms of Parkinson's disease (PD). However, following long-term chronic treatment, the therapeutic effects of L-dopa are often accompanied by debilitating peak-dose dyskinesia. The mechanisms underlying L-dopa induced dyskinesia remain unknown. Rapid increases of dopamine (DA) in the severely DA denervated striatum are associated with L-dopa induced dyskinesia (Miller and Abercrombie, 1999). This DA efflux is believed to cause many post-synaptic changes that are associated with L-dopa induced dyskinesia (Olanow et al., 2000). Therefore, it is of interest to examine the underlying mechanisms of the L-dopa induced DA release. The objectives of the present experiments were to examine the role for the DA transporter (DAT) in mediating L-dopa-induced DA release. Firstly, systemic injection of a DAT antagonist, methylphenidate (MP) was used to assess the role of the DAT in L-dopa induced dyskinesia in chronically L-dopa treated animals. Results showed a dose-dependent effect of MP in the attenuation of L-dopa induced dyskinesia. Secondly, we investigated the functional mode of the DAT by examining the effects of MP pre-treatment on the L-dopa induced DA efflux and dyskinetic responses in three groups of rats 1) L-dopa-naive, 2) 1-week L-dopa treated, and 3) 3-week L-dopa treated, rats. MP pretreatment had no effect on L-dopa induced DA efflux in L-dopa naive, or 1 -week L-dopa treated animals. In contrast, systemic pretreatment of MP significantly attenuated the L-dopa induced DA response in 3-week treated rats, which was correlated with a similar decrease in L-dopa induced dyskinesia. The results from these experiments lend support to our hypothesis that reversal of the DAT through chronic L-dopa treatment contributes to the pathogenesis of L-dopa induced dyskinesia. Therefore, these findings suggest that the DAT is an important pharmacological target in the study and treatment of L-dopa induced dyskinesia.
Relativistic Heavy-Ion Collisions within 3-Fluid Hydrodynamics: Hadronic Scenario

description: A 3-fluid hydrodynamic model for simulating relativistic heavy-ion collisions is introduced. Alongside with two baryon-rich fluids, the new model considers time-delayed evolution of a third, baryon-free (i.e. with zero net baryonic charge) fluid of newly produced particles. Its evolution is delayed due to a formation time, during which the baryon-free fluid neither thermalizes nor interacts with the baryon-rich fluids. After the formation it starts to interact with the baryon-rich fluids and quickly gets thermalized. Within this model with pure hadronic equation of state, a systematic analysis of various observables at incident energies between few and about 160A GeV has been done as well as comparison with results of transport models. We have succeeded to reasonably reproduce a great body of experimental data in the incident energy range of E_{lab} = (1-160)A GeV. The list includes proton and pion rapidity distributions, proton transverse-mass spectra, rapidity distributions of Lambda and antiLambda hyperons, elliptic flow of protons and pions (with the exception of proton v2 at 40A GeV), multiplicities of pions, positive kaons, phi-mesons, hyperons and antihyperons, including multi-strange particles. This agreement is achieved on the expense of substantial enhancement of the interflow friction as compared to that estimated proceeding from hadronic free cross sections. However, we have also found out certain problems. The calculated yield of K^- is approximately by a factor of 1.5 higher than that in the experiment. We have also failed to describe directed transverse flow of protons and pion at E_{lab} > 40A GeV. This failure apparently indicates that the used EoS is too hard and thereby leaves room for a phase transition.

description: A choice experiment was used to examine the value of various fluid milk attributes. Respondents were surveyed regarding half or whole gallon milk purchases. A split-sample design was used to examine consumer inferences regarding food safety. Willingness to pay for verification of production process attributes varied across attributes and verifying entity. Consumers were generally willing to pay substantial premiums for milk produced without the use of rbST, on local family farms, with assured food safety enhancement, and for these claims to be verified by the U.S. Department of Agriculture.

description: The match between the Linac beam energy and the energy determined by the bending field of the Booster magnets is crucial for rf capture, beam quality, and the transmission efficiency in a Booster cycle. The observation of the injection energy match is important for injection tuning. Several signals, such as phase shift drive (PSD), radial position error (RPOS), synchrotron phase (SPD), and fast phase error (FPERR), provide consistent information on the energy match and can be used for a injection match tuning.

description: We present X-ray imaging spectroscopy of one of the weakest active region (AR) microflares ever studied. The microflare occurred at $\sim$11:04 UT on 2018 September 9 and we studied it using the Nuclear Spectroscopic Telescope ARray (NuSTAR) and the Solar Dynamic Observatory's Atmospheric Imaging Assembly (SDO/AIA). The microflare is observed clearly in 2.5-7 keV with NuSTAR and in Fe XVIII emission derived from the hotter component of the 94 $\unicode{x212B}$ SDO/AIA channel. We estimate the event to be three orders of magnitude lower than a GOES A class microflare with an energy of 1.1$\times$10$^{26}$ erg. It reaches temperatures of 6.7 MK with an emission measure of 8.0$\times$10$^{43}$ cm$^{-3}$. Non-thermal emission is not detected but we instead determine upper limits to such emission. We present the lowest thermal energy estimate for an AR microflare in literature, which is at the lower limits of what is still considered an X-ray microflare.

description: We show that adaptive least-squares finite element methods driven by the canonical least-squares functional converge under weak conditions on PDE operator, mesh-refinement, and marking strategy. Contrary to prior works, our plain convergence does neither rely on sufficiently fine initial meshes nor on severe restrictions on marking parameters. Finally, we prove that convergence is still valid if a contractive iterative solver is used to obtain the approximate solutions (e.g., the preconditioned conjugate gradient method with optimal preconditioner). The results apply within a fairly abstract framework which covers a variety of model problems.

description: As the frequency of two-wheeled vehicle driving and related traffic accidents increase, the need for two-wheeled vehicle safety management is emerging. However, the development of quantitative indicators that comprehensively consider various behaviors of two-wheeled vehicle driving has been limited. In this study, 11 evaluation items, such as signal violation, reverse lane driving, central line violation, and speed violation were defined, and the weight was determined using the AHP technique. As the result, helmet violation (0.158), speed violation (0.124), and pedestrian close driving (0.122) had the highest weights. It is expected that the development of two-wheeled vehicle safe driving indicators will be possible through the derived risk criteria and weights.

Trata-se, este trabalho, de um esforço neste sentido, utilizando-se, para tal, do conceito de indicadores DSR, propostos pela ONU. São utilizados os resultados obtidos por Melo (1999) para os indicadores de Estado, dos Fatores Condicionantes, e de Resposta da sustentabilidade para a região do submédio São Franscisco para se estabelecer as forças condicionantes da sustentabilidade, através de uma regressão linear simples entre o índice de sustentabilidade, também estimado por Melo, e os indicadores de fatores condiocionantes e de resposta. Os resultados obtidos confirmam as proposições de que o uso de defensivos agrícolas e a concentração na posse da terra tem impactos adversos sobre a sustentabilidade; mas trazem evidências contrárias sobre o comportamento esperado da concentração de renda, instalação de drenagem e diversificação produtiva. Como principal conclusão infere-se a necessidade de uso de modelos não lineares para o tratamento da questão.

description: The dipole mode synchrotron frequency is a basic beam parameter; it and a few similarly basic quantities measured at small time intervals serve to characterize the longitudinal beam dynamics throughout the acceleration cycle. The effective accelerating voltage, in conjunction with the amount of rf voltage required for the acceleration, is important for the estimate of the beam energy loss per turn. The dipole mode frequency can be used to obtain the effective accelerating rf voltage, providing that it can be measured precisely. The synchrotron frequency measured from the synchrotron phase detector signal (SPD) generally agrees well with calculation, and it can be applied for such purposes as inferring the effective rf voltage.

description: In the rapidly growing two-wheeled vehicle industry, there is an increasing need to detect and prevent aggressive driving behaviors. In this study, we propose an effective method to identify aggressive driving behaviors of simulated two-wheeled vehicles using limited data from the Carla simulator. We focus on two types of aggressive driving behaviors: sharp turning and sharp lane changing. By utilizing acceleration, angular velocity, and position data, we establish a foundation for detecting these behaviors. For sharp turning, a multi-stage classification method is adopted using gyroscope and acceleration data. Sharp lane changings are detected using an XGBoost mode

One can trade accuracy for speed and find a part of the database (a block) containing the target item even faster, this is partial search. A partial search algorithm was recently suggested by Grover and Radhakrishnan. Here we optimize it. Efficiency of the search algorithm is measured by number of queries to the oracle. The author suggests new version of Grover-Radhakrishnan algorithm which uses minimal number of queries to the oracle. The algorithm can run on the same hardware which is used for the usual Grover algorithm.

description: Fine localization is a crucial task for autonomous vehicles. Although many algorithms have been explored in the literature for this specific task, the goal of getting accurate results from commodity sensors remains a challenge. As autonomous vehicles make the transition from expensive prototypes to production items, the need for inexpensive, yet reliable solutions is increasing rapidly. This article considers scenarios where images are captured with inexpensive cameras and localization takes place using pre-loaded fine maps of local roads as side information. The techniques proposed herein extend schemes based on normalized mutual information by leveraging the likelihood of shades rather than exact sensor readings for localization in noisy environments. This algorithmic enhancement, rooted in statistical signal processing, offers substantial gains in performance. Numerical simulations are used to highlight the benefits of the proposed techniques in representative application scenarios. Analysis of a Ford image set is performed to validate the core findings of this work.

description: Understanding the transition-crossing process is crucial for improving Booster performance at high intensity. The synchronous phase appears to drop toward 90 degrees right after transition regardless of beam intensity, more so at higher beam intensity. The implication is that the effective rf voltage (RFSUM) will run into a limit right after transition when the synchronous phase reaches 90 degrees for high intensity beam. A reduction in RFSUM is also observed at the same time. Solutions, such as raising the rf voltage during the transition period or controlling the RFSUM reduction by increasing longitudinal emittance before transition, are potentially important for high intensity operation.

description: We study the non-linear beam splitter in matter-wave interferometers using ultracold quantum gases in a double-well configuration in presence of non-local interactions inducing inter-well density-density coupling, as they can be realized, e.g., with dipolar gases. We explore this effect after considering different input states, in the form of either coherent, or Twin-Fock, or NOON states. We first review the non-interacting limit and the case in which only the local interaction is present, including the study of sensitivity near the self-trapping threshold. Then, we consider the two-mode model in the presence of inter-well interactions and consider the scaling of the sensitivity as a function of the non-local coupling strength. Our analysis clearly shows that non-local interactions can compensate the degradation of the sensitivity induced by local interactions, so that they may be used to restore optimal sensitivity.

description: In recent years, the long-term preservation of digital records has received increasing attention. Several research initiatives have focused upon the challenges presented by the preservation of digital photography. They have primarily addressed issues related to continuing access to accurate and authentic images. These initiatives are aware of the fundamental difference between preservation of analogue photographs and preservation of digital photographs. While the key factors allowing for digital preservation are media stability and technological interoperability, central to the scholarly discourse is the changing role of the creator (i.e., the photographer), who is becoming responsible for performing the functions traditionally carried out by the preserver (i.e., archivist). This thesis contributes to such discourse by investigating the creation, use, and preservation of born digital images as reliable and authentic records. It does so by studying existing literature in the archival-diplomatic, legal, and photographic fields; analyzing the results of a survey of the recordkeeping activities of digital photographers; examining existing best practices and standards, especially as regards metadata schemas for digital photographs; and comparing the findings of these research activities with protocols for record authenticity. This study reaches several conclusions. First, an interdisciplinary approach to the topic of digital preservation should incorporate the concerns of both creators and preservers. Second, although photographers are concerned about the reliability and authenticity of their born digital images, they should be informed of the conceptual and methodological thinking that supports best practices for creating, maintaining, and preserving reliable and authentic records. Third, current standards and best practices promulgated by the digital imaging community are a solid foundation on which it is possible to build a trusted recordkeeping system. Fourth, contemporary archival diplomatics provides a valid measurement of the effectiveness of existing standards to document the identity of born digital images and attest to their integrity over time. Lastly, strategies to ensure the reliability and authenticity of born digital images should be developed on the basis of the requirements of the creator's operating environment.

description: Plastics have become one of the most important materials in the automotive sector due to their outstanding mechanical performances and high potential in weight reduction and thus enhancing the OEMs to reduce the carbon dioxide (CO2) emissions of the vehicles. The European Unions regulations for limiting CO2 emissions is one of the biggest challenges for the European automotive industry. On the other hand the European Commissions, End-of-life Vehicle (ELV) Directive requires higher recovery and recycling rates and reduce the amount of automotive shredder residue ending up as landfills. The increasing weight percentage of plastics in present new vehicles, will require high share of plastics recycling once they attain their end-of-life, to achieve the recycling targets. OEMs already started setting commitments to reduce waste and incorporate, for example up to 25% of recycled plastics materials in the new cars by 2025, which is a big challenge.Polypropylene (PP), the largely used thermoplastics in the automotive has enormous po-tential as a new supply source for the automotive industry in attaining the regulatory re-quirements for end-of-life vehicles. But the current recycling process is very challenging in terms of costs, technology requirements and quality. The processing steps of automotive (AU) plastics recycling includes: dismantling, sorting & separating, shredding, up-scaling by compounding. The volume of polypropylene recovered from the ELVs are currently not high enough, which makes the recycled material cost unattractive for the customers.This research focuses on analysing the automotive plastics closed loop recycling industry structure, the challenges and threats involved in the automotive plastics recycling process and finally to propose solutions to increase the plastics recycling volume, quality and their usage in the automotive sector, concentrating on the European market. The outcome of the study reveals that besides the ELV management, front loading of design for recycling during the plastics part development phase is crucial. This can avoid multi-material part design and hence ease the dismantling, sorting of materials from ELVs and additionally reduce the loss of plastic materials during ELV recycling process. The PP bumpers case study demonstrate that the standardisation of material specifications for automotive applications has great potential to increase the volume of quality feedstock for recycling.

description: E-Scooters are everywhere nowadays. They seem to be well accepted by general population and are quickly gaining popularity among all ages and social classes. Lightweight, compact, easy to use, they appear to be one of the best tool for promoting the micro-mobility and environmental sustainability. On the other hand, there are many both apparent and concealed risks, limitations, and controversies associated with E-Scooters. They present a safety hazard for their own users as well as other traffic participants, mainly pedestrians. Their contribution to well-being of users is questionable, for they seem to augment the most common disease of today - sedentary lifestyle. By depriving individuals of physical activity, e.g. walking the “first and last miles”, E-Scooters have potential of causing serious implications for peoples health. Their practicality in winter season is uncertain. Their environmental impact is also currently unclear. Their actual CO2 footprint is not clearly defined and is often overlooked. Short shelf and operational life, toxic batteries, poor traceability, are all factors that should be taken into consideration and are often not. The explosion of E-Scooters seems to have caught authorities and regulators off guard. But they are rapidly starting to address the issue by creating and enforcing E-Scooter rules. No doubt that E-Scooters will survive. The question is how extensive their participation in total traffic will be after restrictions are introduced. This Masters Thesis clarifies the future of E-Scooters in Vienna`s micro-mobility scheme and focuses on E-Scooters potential to reduce motorized individual traffic (MIT) in the inner part of Vienna. It goes on to determine how many cars could be replaced by E-Scooters and quantifies the impact on emission of CO2 and air pollutants.

description: We study the electromagnetic beam reflection from layered structures that include the so-called double-negative materials, also called left-handed metamaterials. We predict that such structures can demonstrate a giant lateral Goos-Hanchen shift of the scattered beam accompanied by splitting of the reflected and transmitted beams due to the resonant excitation of surface waves at the interfaces between the conventional and double-negative materials as well as due to excitation of leaky modes in the layered structures. The beam shift can be either positive or negative, depending on the type of the guided waves excited by the incoming beam. We also perform finite-difference time-domain simulations and confirm the major effects predicted analytically.

description: Diversos trabalhos evidenciam que países pobres apresentam população com saúde precária. E a relação entre saúde e pobreza é tratada, na literatura, como sendo possivelmente bi-causal, uma vez que um baixo nível de renda causaria saúde precária, e essa por sua vez, tenderia a causar um baixo nível de renda. Assim, existiria um círculo vicioso, constituindo a chamada armadilha saúde-pobreza. No Brasil, de 1981 a 2005, houve uma redução de 10,16% na proporção de pobres, e de 73,70% na taxa de mortalidade na infância, considerando dados do IPEADATA e DATASUS. Com base nessas considerações, o objetivo do presente trabalho é analisar a existência de causalidade entre alguns indicadores de pobreza e saúde. É utilizada uma extensão do teste de causalidade Granger para dados em painel, utilizando-se os estados do Brasil, no período de 1981-2005. Espera-se que o presente trabalho contribua ao melhor entendimento da relação entre essas duas variáveis, de tal forma que oriente a formulação de políticas públicas que objetivem a melhora do bem-estar da população. Os principais resultados mostram uma relação bi-causal entre saúde e pobreza.------------------------ Many works evidence that poor countries present population with poor health. And the relation between health and poverty is treated, in literature, as being possibly bi-causal, since a low income level would cause a poor health, and this one would tend to cause a low income level. Thus, a vicious circle would exist, constituting the so calling trap health-poverty. In Brazil, from 1981 to 2005, there was a reduction of 10,16% in the poverty, and 73,70% in the child mortality rate, considering the data of IPEADATA and DATASUS. Basing in these considerations, the objective of the present paper is to analyze the causality existence among some poverty and health indicators. An extension of the Granger causality test for panel data is used, using the states of Brazil, from the period of 1981-2005. It hopes that the present paper contributes for a better understanding of the relation between these two variables, in a way that will guide the formularization of public policies that objectify the improvement of welfare of the population. The results indicate the existence of bi-causal relationship between health and poverty.

description: The problems of administration simply based on administrative unit that does not consider the operational purpose of the system have been consistently mentioned. For example, in the Republic of Korea, sex offenders information is notified by mail only in some regions. However, the information of sex offenders is notified based on the administrative ‘Dong’ of the offender's residence, so even if you live in the building next to the offender, you cannot be notified because the dong of residence is different. Therefore, in this study, the problems of administration that did not consider the realistic scope were analyzed using the case of sex offender. By expanding the distance, we derived the extent of the sex offenders notification problem. Also, in order to determine whether this problem occurred by chance at a specific point in time or a fundamental limitation in administration, Monte Carlo simulation were applied to compare the degree of problems in actual residence and random residence data.

description: We present the results of a detailed set of one-zone models that account for the coupling between pulsation and convection following the original prescriptions of Stellingwerf (1986). Motivated by the arbitrary nature of the input parameters adopted in this theoretical framework, we computed several sequences of models that cover a substantial fraction of the parameter space and a longer integration time. We also included a turbulent pressure term and found that this physical mechanism plays a crucial role in the pulsation characteristics of the models by removing the sharp discontinuities along the light and the velocity curves showed by models that do not account for turbulent pressure. Finally, we investigated the vibrational and the pulsational stability of completely convective models. We consider as the most important finding of the present work the identification of a well-defined region in the parameter space where they approach limit-cycle stability. Several numerical experiments performed by adopting different values of the adiabatic exponent and of the shell thickness indicate that the coupling between pulsation and convection is the key driving mechanism for LPVs, a finding supported by recent theoretical predictions.
