description: The present study aims at evaluating how YouTube users understand, negotiate and appropriate science-related knowledge on YouTube. It is informed by the qualitative analysis of post-video discussions around visual scenarios of sea-level rise (SLR) triggered by climate change. On the one hand, the SLR maps have an exemplary status as contemporary visualizations of climate change risks, beyond traditional image categories such as scientific or popular imagery. YouTube, on the other hand, is a convenient media environment to investigate the situated appropriation of such visual knowledge, considering its increasing relevance as a navigational platform to provide, search, consume and debate science-related information. The paper draws on media practice theory and operationalizes digital methods and qualitative coding informed by Grounded Theory. It characterizes a number of communicative practices of articulated knowledge appropriation regarding climate knowledge. This includes “locating impacts,” “demanding representation,” “envisioning further,” “debating future action,” “relativizing the information,” “challenging the reality of anthropogenic climate change,” “embedding popular narratives,” “attributing to politics,” and “insulting others.” The article then discusses broader questions posed by the comments and related to the appropriation and discursive negotiation of knowledge within online video-sharing platforms. Ambiguity is identified as a major feature within the practice of science-related information retrieval and knowledge appropriation on YouTube. This consideration then serves as an opportunity to reconsider the relationship between information credibility and knowledge appropriation in the age of the digital. Findings suggest that ambiguity of information can have a positive impact on problem definition, future imagination and the discursive negotiation of climate change.

description: We have measured the flux, profile, color, and substructure in the diffuse intracluster light (ICL) in a sample of ten galaxy clusters with a range of mass, morphology, redshift, and density. Deep, wide-field observations for this project were made in two bands at the one meter Swope and 2.5 meter du Pont telescope at Las Campanas Observatory. Careful attention in reduction and analysis was paid to the illumination correction, background subtraction, point spread function determination, and galaxy subtraction. ICL flux is detected in both bands in all ten clusters ranging from 7.6 x 10^{10} to 7.0 x 10^{11} h^{-1} solar luminosities in r and 1.4 x 10^{10} to 1.2 x 10^{11} h^{-1} solar luminosities in the B-band. These fluxes account for 6 to 22% of the total cluster light within one quarter of the virial radius in r and 4 to 21% in the B-band. Average ICL B-r colors range from 1.5 to 2.8 mags when k and evolution corrected to the present epoch. In several clusters we also detect ICL in group environments near the cluster center and up to ~1 h^{-1} Mpc distant from the cluster center. Our sample, having been selected from the Abell sample, is incomplete in that it does not include high redshift clusters with low density, low flux, or low mass, and it does not include low redshift clusters with high flux, mass, or density. This bias makes it difficult to interpret correlations between ICL flux and cluster properties. Despite this selection bias, we do find that the presence of a cD galaxy corresponds to both centrally concentrated galaxy profiles and centrally concentrated ICL profiles. This is consistent with ICL either forming from galaxy interactions at the center, or forming at earlier times in groups and later combining in the center.

description: The recent demonstration of MoSi2N4 and its exceptional stability to air, water, acid, and heat has generated intense interest in this family of two-dimensional (2D) materials. Among these materials, NbSi2N4, VSi2N4, and VSi2P4 are semiconducting, easy-plane ferromagnets with negligible in-plane magnetic anisotropy. They thus satisfy a necessary condition for exhibiting a dissipationless spin superfluid mode. The Curie temperatures of monolayer VSi2P4 and VSi2N4 are determined to be above room temperature based on Monte Carlo and density functional theory calculations. The magnetic moments of VSi2N4 can be switched from in-plane to out-of-plane by applying tensile biaxial strain or electron doping.

description: Microplastics (MPs) are ubiquitously found in terrestrial ecosystems and are increasingly recognized as a factor of global change (GCF). Current research shows that MP can alter plant growth, soil inherent properties, and the composition and activity of microbial communities. However, knowledge about how microplastic affects arbuscular mycorrhizal fungi (AMF) is scarce. For plants it has been shown that microplastic can both increase and decrease the aboveground biomass and reduce the root diameter, which could indirectly cause a change in AMF abundance and activity. One of the main direct effects of microplastic is the reduction of the soil bulk density, which translates to an altered soil pore structure and water transport. Moreover, especially fibers can have considerable impacts on soil structure, namely the size distribution and stability of soil aggregates. Therefore, microplastic alters a number of soil parameters that determine habitat space and conditions for AMF. We expect that this will influence functions mediated by AMF, such as soil aggregation, water and nutrient transport. We discuss how the impacts of microplastic on AMF could alter how plants deal with other GCFs in the context of sustainable food production. The co-occurrence of several GCFs, e.g., elevated temperature, drought, pesticides, and microplastic could modify the impact of microplastic on AMF. Furthermore, the ubiquitous presence of microplastic also relates to earth system processes, e.g., net primary production (NPP), carbon and nitrogen cycling, which involve AMF as key soil organisms. For future research, we outline which experiments should be prioritized.

description: L’écrit étant omniprésent dans notre société, savoir lire et écrire est essentiel pour l’autonomie, la qualité de vie et l’épanouissement personnel de toute personne. Bien que l’apprentissage de la lecture soit un réel défi pour des élèves avec une déficience intellectuelle, les différentes études révèlent qu’il est tout à fait possible pour eux d’apprendre à lire. Cette réussite dépendra certes de leurs capacités intellectuelles, mais ils devront surtout bénéficier d’un enseignement explicite, systématique et intensif de la conscience phonologique, des correspondances graphème-phonème, du décodage et de l’encodage. L’enseignant devra aussi faire preuve de persévérance car cet apprentissage demandera plus de temps à ces élèves. Les élèves ayant une déficience intellectuelle et des besoins complexes en communication ont peu ou pas de langage oral et doivent donc avoir recourt à des moyens alternatifs et augmentés pour parvenir à communiquer efficacement. L’apprentissage de la lecture est d’autant plus complexe, mais quelques rares recherches anglophones s’accordent à dire qu’il leur est également possible d’acquérir les compétences nécessaires pour lire lorsqu’un enseignement adapté leur est proposé. Ce mémoire s’inscrit dans le cadre du projet de recherche ELODI II « Enseigner la lecture de manière optimale aux élèves ayant une déficience intellectuelle et des besoins complexes de communication » dirigé par Rachel Sermier Dessemontet. Pendant plusieurs mois, avec mon élève, nous avons testé le matériel pédagogique de la méthode DÉCODI (de Chambrier & al., 2012) adapté pour des personnes avec des besoins complexes de communication. Afin d’évaluer les effets de cette intervention, des tests standardisés ont été réalisés avant et après celle-ci. Les résultats obtenus mettent en évidence les magnifiques progrès réalisés par cet élève dans la connaissance des correspondances graphème-phonème, du décodage de syllabes et de mots. Ils sont très encourageants pour la suite du projet d’étude ELODI II. Ces ressources pédagogiques pourront bientôt profiter à tous les élèves ayant une déficience intellectuelle et des besoins complexes de communication ainsi qu’à leurs enseignants.

Χρησιμοποιήθηκε δείγμα αποτελούμενο από σαράντα ολικά νωδούς ασθενείς με προϋπάρχουσες Ο.Ο. Βάση του πρωτοκόλλου κατασκευής, διαχωρίστηκαν τυχαία, σε δύο ομάδες των είκοσι ατόμων και στη συνέχεια, κάθε ομάδα σε δυο υποομάδες. Στην αρχή της μελέτης, στον 3μηνο και στον 6μηνο επανέλεγχο διανεμήθηκαν ερωτηματολόγια για τους δείκτες OHIP-20 και τον δείκτη ικανοποίησης των ασθενών. Κατά την αρχική περίοδο προσαρμογής των Ο.Ο. σημειώθηκε η εντόπιση των επώδυνων σημείων στον στοματικό βλεννογόνο. Παρατηρήθηκε αύξηση του δείκτη γενικής ικανοποίησης και αντίστοιχα μείωση του συνολικού δείκτη OHIP-20 και στις τέσσερις υπό εξέταση ομάδες. Ο ρυθμός προσαρμογής και ο βαθμός αποδοχής των ασθενών του δείγματος στις νέες Ο.Ο. δεν επηρεάστηκε αρνητικά από το διαφορετικό πρωτόκολλο κατασκευής τους, ούτε από τον διαφορετικό τύπο αποδιδόμενης σύγκλεισης.
description: The aim of present thesis was to register the patients’ adaptation and acceptance to conventional complete dentures fabricated with two different construction protocols. Forty complete denture wearers, who sought replacement dentures because of complaints (material degradation or unsatisfactory repaired fractures) associated with them, were selected. Based on the construction protocol, the study participants were initially divided into two groups and then each group into two subgroups. Pre-treatment, three and six months post-treatment the participants completed the OHIP-20 and Complete Denture Satisfaction questionnaires. During the initial adaptation/adjustment period, the location and number of sore spots were recorded on a customized data sheet. Patients’ overall acceptance of their newly constructed complete dentures improved significantly for all groups. The adaptation and acceptance of conventional complete dentures by the patients were independent of the fabrication protocol and the occlusal scheme used for the construction of their prostheses. Duplicate dentures with bilateral balanced occlusion exhibited significant less sore spots than those constructed with the same occlusal scheme but a conventional construction protocol.

description: The dark matter (DM) can consist of the primordial black holes (PBHs) in addition to the conventional weakly interacting massive particles (WIMPs). The Poisson fluctuations of the PBH number density produce the isocurvature perturbations which can dominate the matter power spectrum at small scales and enhance the early structure formation. We study how the WIMP annihilation from those early formed structures can affect the CMB (in particular the E-mode polarization anisotropies and $y$-type spectral distortions) and global 21cm signals. Our studies would be of particular interest for the light (sub-GeV) WIMP scenarios which have been less explored compared with the mixed DM scenarios consisting of PBHs and heavy ($\gtrsim 1$ GeV) WIMPs. For instance, for the self-annihilating DM mass $m_χ=1$ MeV and the thermally averaged annihilation cross section $\langle σv \rangle \sim 10^{-30} \rm cm^3/s$, the latest Planck CMB data requires the PBH fraction with respect to the whole DM to be at most ${\cal O}(10^{-3})$ for the sub-solar mass PBHs and an even tighter bound (by a factor $\sim 5$) can be obtained from the global 21-cm measurements.

Meanwhile, on the grounds of NASA Science Working Group Report in 1984, we reexamine the strategy of Search for Extraterrestrial Intelligence (SETI). A mathematical analysis of the radar equation will be performed in the first section, aiming to make it convenient to design a receiver system that can detect activities of an extraterrestrial civilization, according to the observable region of the narrowband. Taking advantage of the inherent potential of FAST, we simulate the theoretical detection of a Kardashev Type I civilization by a snowflake-selected reflecting area.

description: The motivations to make ultraviolet (UV) studies of supernovae (SNe) are reviewed and discussed in the light of the results obtained so far by means of IUE and HST observations. It appears that UV studies of SNe can, and do lead to fundamental results not only for our understanding of the SN phenomenon, such as the kinematics and the metallicity of the ejecta, but also for exciting new findings in Cosmology, such as the tantalizing evidence for "dark energy" that seems to pervade the Universe and to dominate its energetics. The need for additional and more detailed UV observations is also considered and discussed.

Invariant relative timing in the learning of a perceptual motor skill
Creators: name: Stanley, Mary Louise
Publisher: name: University of British Columbia
Year: 2010

description: The concept of invariant relative timing has typically been associated with the concept of a generalized motor program. The present study approaches the phenomenon of invariant relative timing from the perspective of learning. The underlying question of concern for this study is "What is learned?". The specific question addressed by the present study is whether relative timing is one of the essential properties of movement that is learned during skill acquisition. In the present experiment, subjects were given extensive practice in learning to visually track and reproduce a criterion waveform using a joystick control for their response. In order to test whether subjects learn the relative timing of a movement, they were transferred to waveforms which were identical to the criterion in terms of relative timing, but different in terms of absolute timing. Measurements were taken on all waveforms in two conditions: 1) in a pursuit tracking condition where subjects were temporally constrained by the stimulus, and 2) in a reproduction condition where subjects' timing was not constrained. Pursuit tracking performance was evaluated using three dependent measures: RMS error, lead-lag index, and variability. Performance in the reproduction condition was subjected to three analyses: 1) an harmonic analysis, which described each response waveform in terms of its phase, frequency, amplitude, and period; 2)proportional interval durations; and 3) proportional interval displacements. The outcome from both conditions gives support to the idea that the invariant relative timing of movement is one of the aspects of a movement that humans learn.

description: Fluctuations in the abundance of molecules in the living cell may affect its growth and well being. For regulatory molecules (e.g., signaling proteins or transcription factors), fluctuations in their expression can affect the levels of downstream targets in a network. Here, we develop an analytic framework to investigate the phenomenon of noise correlation in molecular networks. Specifically, we focus on the metabolic network, which is highly inter-linked, and noise properties may constrain its structure and function. Motivated by the analogy between the dynamics of a linear metabolic pathway and that of the exactly soluable linear queueing network or, alternatively, a mass transfer system, we derive a plethora of results concerning fluctuations in the abundance of intermediate metabolites in various common motifs of the metabolic network. For all but one case examined, we find the steady-state fluctuation in different nodes of the pathways to be effectively uncorrelated. Consequently, fluctuations in enzyme levels only affect local properties and do not propagate elsewhere into metabolic networks, and intermediate metabolites can be freely shared by different reactions. Our approach may be applicable to study metabolic networks with more complex topologies, or protein signaling networks which are governed by similar biochemical reactions. Possible implications for bioinformatic analysis of metabolimic data are discussed.

description: At optical wavelengths, blazar Electric Vector Position Angle (EVPA) rotations linked with gamma-ray activity have been the subject of intense interest and systematic investigation for over a decade. One difficulty in the interpretation of EVPA rotations is the inherent 180° ambiguity in the measurements. It is therefore essential, when studying EVPA rotations, to ensure that the typical time-interval between successive observations -- i.e. the cadence -- is short enough to ensure that the correct modulo 180° value is selected. This optimal cadence depends on the maximum intrinsic EVPA rotation speed in blazars, which is currently not known. In this paper we address the following questions for the RoboPol sample: What range of rotation speeds for rotations greater than 90° can we expect? What observation cadence is required to detect such rotations? Have rapid rotations been missed in EVPA rotation studies thus far? What fraction of data is affected by the ambiguity? And how likely are detected rotations affected by the ambiguity? We answer these questions with three seasons of optical polarimetric observations of a statistical sample of blazars sampled weekly with the RoboPol instrument and an additional season with daily observations. We model the distribution of EVPA changes on time scales from 1-30 days and estimate the fraction of changes exceeding 90°. We show that at least daily observations are necessary to measure >96% of optical EVPA variability in the RoboPol sample of blazars correctly and that intra-day observations are needed to measure the fastest rotations that have been seen thus far.

Considering the strong dependence of planet frequency on stellar metallicity, we studied the metal rich old open cluster NGC 6791 and searched for close-in planets using the transit technique. Methods. A ten-night observational campaign was performed using the Canada-France-Hawaii Telescope (3.6m), the San Pedro Mártir telescope (2.1m), and the Loiano telescope (1.5m). To increase the transit detection probability we also made use of the Bruntt et al. (2003) eight-nights observational campaign. Adequate photometric precision for the detection of planetary transits was achieved. Results. Should the frequency and properties of close-in planets in NGC 6791 be similar to those orbiting field stars of similar metallicity, then detailed simulations foresee the presence of 2-3 transiting planets. Instead, we do not confirm the transit candidates proposed by Bruntt et al. (2003). The probability that the null detection is simply due to chance coincidence is estimated to be 3%-10%, depending on the metallicity assumed for the cluster. Conclusions. Possible explanations of the null-detection of transits include: (i) a lower frequency of close-in planets in star clusters; (ii) a smaller planetary radius for planets orbiting super metal rich stars; or (iii) limitations in the basic assumptions. More extensive photometry with 3-4m class telescopes is required to allow conclusive inferences about the frequency of planets in NGC 6791.

description: Stellar winds from fast-rotating Population III (Pop III) stars have long been suspected to make important contributions to early metal enrichment, as features in the nucleosynthesis of such `spinstars' are consistent with the chemical abundance patterns of some metal-poor stars in the local Universe. Particularly, stellar winds rich in light elements can provide another pathway towards explaining the carbon enhancement in carbon-enhanced metal-poor (CEMP) stars. In this work, we focus on the feedback of Pop III stellar winds combined with supernovae (SNe), and derive the resulting chemical signatures in the enriched medium. We explore a large parameter space of Pop III star formation, feedback, yields from winds and SNe with a semi-analytical model. The predicted pattern of carbon and iron abundances of second-generation stars agrees well with observations of CEMP-no stars ($[\rm Ba/Fe]<0$) at $[\rm Fe/H]\lesssim -3$ and $A(\mathrm{C})\lesssim 7$, under the optimistic assumption of significant mass loss by winds from massive ($\gtrsim 25\ \rm M_{\odot}$) stars that collapse into BHs without SNe. In this scenario, carbon-rich but iron-free second-generation stars can form in systems dominated by enrichment from winds, gaining trace amounts of iron by accretion from the interstellar medium, to become the most iron-poor and carbon-enhanced stars seen in observations ($[\rm Fe/H]\lesssim -4$, $[\rm C/Fe]\gtrsim 2$). We conclude that the observed CEMP-no stars can be explained by both our winds + ISM accretion channel as well as the well-studied faint SN scenario. Wind feedback from Pop~III spinstars deserves more detailed modelling in early cosmic structure formation.

description: We investigate the $H_0$ tension in a range of extended model frameworks beyond the standard $Λ$CDM without the data from cosmic microwave background (CMB). Specifically, we adopt the data from baryon acoustic oscillation, big bang nucleosynthesis and type Ia supernovae as indirect measurements of $H_0$ to study the tension. We show that the estimated value of $H_0$ from indirect measurements is overall lower than that from direct local ones regardless of the data sets and a range of extended models to be analyzed, which indicates that, although the significance of the tension varies depending on models, the $H_0$ tension persists in a broad framework beyond the standard $Λ$CDM model even without CMB data.

description: We report a refractive index sensor comprising of unique T grating on top of periodic nano-cavities. The sensor has two resonant modes sensitive to different regions of the structure with low inter-region interference, hence allows simultaneous detection of two different analytes or more accurate detection of a single analyte. The sensor also provides a self-referencing feature for a broad range of refractive index, from 1.3 to 1.5. Using the FDTD method, the sensitivities of 801.7 nm/RIU and 1386.8 nm/RIU have been recorded for the two modes respectively. The versatility of the structure makes the sensor a prominent candidate for biochemical and other sensing applications.

description: Η διδακτορική διατριβή του Παύλου Σεραφείμ στο τμήμα Θεολογίας της Θεολογικής Σχολής του Α.Π.Θ. έχει τίτλο: «Η εκλογή του Αρχιεπισκόπου Αμερικής Αθηναγόρα στον Οικουμενικό Θρόνο (1946-1948)». Σε αυτήν εξετάζονται τα γεγονότα και οι εξελίξεις που συνέβησαν κατά κύριο λόγο τη διετία 1946 – 1948 και οδήγησαν στην άνοδο στον Οικουμενικό Θρόνο του Αρχιεπισκόπου Βορείου και Νοτίου Αμερικής Αθηναγόρα Σπύρου. Κατά τον συγγραφέα, η έρευνά του σε Αθήνα, Κωνσταντινούπολη, Νέα Υόρκη, Ουάσινγκτον και Λονδίνο επιτρέπει ασφαλή συμπεράσματα για την εκλογή εκείνη, η οποία ήταν αποτέλεσμα του Ψυχρού Πολέμου. Τα επιμέρους θέματα της διδακτορικής διατριβής αναφέρονται στο διεθνές πλαίσιο της εποχής του Ψυχρού Πολέμου ειδικά για την περιοχή της Νοτιοανατολικής Ευρώπης, στη θέση της Ελληνορθόδοξης Εκκλησίας και ειδικά του Οικουμενικού Πατριαρχείου στο πλαίσιο αυτό και στην ανάλυση του παρασκηνίου της συγκεκριμένης εκλογής. Το παρασκήνιο αυτό είναι ιδιαίτερα ενδιαφέρον, καθώς τρεις κυβερνήσεις, η ελληνική, η τουρκική και η αμερικανική, αναμίχθηκαν στην εκλογική διαδικασία υποστηρίζοντας τον Αθηναγόρα, διότι θεωρούσαν ότι με εκείνον επικεφαλής το Οικουμενικό Πατριαρχείο θα χρησίμευε ως αντίβαρο στην αύξηση της επιρροής της υπό σοβιετικό έλεγχο Ρωσικής Ορθόδοξης Εκκλησίας στην περιοχή της Νοτιοανατολικής Ευρώπης.
description: Pavlos Serafeim’ s doctoral thesis in the Faculty of Theology of the Aristotle University of Thessaloniki, Greece, is about the election of the Archbishop of Northern and Southern America Athenagoras as Εcumenical Patriarch in 1948. Pavlos Serafeim believes that his research work in Athens, Istanbul, New York, Washington DC and London permits the exaggeration of safe conclusions about this election which, in his opinion, was a product of the Cold War Era. The topics of the doctoral thesis refer to the international framework of the Cold War in the region of Eastern and Southern Europe, the position of the Greek - Orthodox Church and especially of the Εcumenical Patriarchate in that framework, and the analysis of the backstage of the election of Athenagoras. This backstage is of special interest because three governments, the Greek, the Turkish and the American, favored Athenagoras to become an Εcumenical Patriarch as they thought he would be able to use the Εcumenical Patriarchate as a counterweight in the influence of the soviet dominated Russian Church in the orthodox world.

description: Hot, dust-obscured galaxies (Hot DOGs) are a population of hyper-luminous obscured quasars identified by WISE. We present ALMA observations of the [CII] fine-structure line and underlying dust continuum emission in a sample of seven of the most extremely luminous (EL; L$_{\rm bol}$ $\ge$ 10$^{14}$ L$_\odot$) Hot DOGs, at redshifts z ~ 3.0-4.6. The [CII] line is robustly detected in four objects, tentatively in one, and likely red-shifted out of the spectral window in the remaining two based on additional data. On average, [CII] is red-shifted by ~ 780 km/s from rest-frame ultraviolet emission lines. EL Hot DOGs exhibit consistently very high ionized gas surface densities, with $Σ_{\rm [CII]}$ ~ 1-2 x 10$^{9}$ L$_\odot$ kpc$^{-2}$; as high as the most extreme cases seen in other high-redshift quasars. As a population, EL Hot DOG hosts seem to be roughly centered on the main-sequence of star forming galaxies, but the uncertainties are substantial and individual sources can fall above and below. The average, intrinsic [CII] and dust continuum sizes (FWHMs) are ~ 2.1 kpc and ~ 1.6 kpc, respectively, with a very narrow range of line-to-continuum size ratios, 1.61 $\pm$ 0.10, suggesting they could be linearly proportional. The [CII] velocity fields of EL Hot DOGs are diverse: from barely rotating structures, to resolved hosts with ordered, circular motions, to complex, disturbed systems that are likely the result of ongoing mergers. In contrast, all sources display large line-velocity dispersions, FWHM $\gtrsim$ 500 km/s, which on average are larger than optically and IR-selected quasars at similar or higher redshifts. We argue that one possible hypothesis for the lack of a common velocity structure, the systematically large dispersion of the ionized gas, and the presence of nearby companion galaxies may be that, rather than a single event, the EL Hot DOG phase could be recurrent.

description: We argue that quantum gravity theories that carry a Lie algebraic modification of the Poincare' and Heisenberg algebras inevitably provide inhomogeneities that may serve as seeds for cosmological structure formation. Furthermore, in this class of theories one must expect a strong polarisation and spin dependence of various quantum-gravity effects.

Neural Weighted A*: Learning Graph Costs and Heuristics with Differentiable Anytime A*

description: Recently, the trend of incorporating differentiable algorithms into deep learning architectures arose in machine learning research, as the fusion of neural layers and algorithmic layers has been beneficial for handling combinatorial data, such as shortest paths on graphs. Recent works related to data-driven planning aim at learning either cost functions or heuristic functions, but not both. We propose Neural Weighted A*, a differentiable anytime planner able to produce improved representations of planar maps as graph costs and heuristics. Training occurs end-to-end on raw images with direct supervision on planning examples, thanks to a differentiable A* solver integrated into the architecture. More importantly, the user can trade off planning accuracy for efficiency at run-time, using a single, real-valued parameter. The solution suboptimality is constrained within a linear bound equal to the optimal path cost multiplied by the tradeoff parameter. We experimentally show the validity of our claims by testing Neural Weighted A* against several baselines, introducing a novel, tile-based navigation dataset. We outperform similar architectures in planning accuracy and efficiency.
A Mechanical Model for Magnetized Relativistic Blastwaves

description: The evolution of a relativistic blastwave is usually delineated under the assumption of pressure balance between forward- and reverse-shocked regions. However, such a treatment usually violates the energy conservation law, and is inconsistent with existing MHD numerical simulation results. A mechanical model of non-magnetized blastwaves was proposed in previous work to solve the problem. In this paper, we generalize the mechanical model to the case of a blastwave driven by an ejecta with an arbitrary magnetization parameter $σ_{\rm ej}$. We test our modified mechanical model by considering a long-lasting magnetized ejecta and found that it is much better than the pressure-balance treatment in terms of energy conservation. For a constant central engine wind luminosity $L_{\rm ej} = 10^{47}{\rm erg~s^{-1}}$ and $σ_{\rm ej} < 10$, the deviation from energy conservation is negligibly small at small radii, but only reaches less than $25\%$ even at $10^{19}{\rm cm}$ from the central engine. For a finite life time of the central engine, the reverse shock crosses the magnetized ejecta earlier for the ejecta with a higher $σ_{\rm ej}$, which is consistent with previous analytical and numerical results. In general, the mechanical model is more precise than the traditional analytical models with results closer to those of numerical simulations.
