The Supersymmetric Leptophilic Higgs Model
Creators: name: Marshall, Gardner

Publisher: name: arXiv
Year: 2010
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: In the leptophilic model, one Higgs doublet couples to quarks and another couples to leptons. We study the supersymmetric version of this model, concentrating on the tightly constrained Higgs sector, which has four doublets. Constraints from perturbativity, unitarity, and LEP bounds are considered. It is found that the lightest Higgs, h, can have a mass well below 114 GeV, and for masses below 100 GeV will have a substantially enhanced branching ratio into tau pairs. For this region of parameter space, traditional production mechanisms (Higgs-strahlung, W fusion and gluon fusion) are suppressed, but it may be produced in the decay of heavier particles. The second lightest Higgs has a mass of approximately 110 GeV for virtually all of parameter space, with Standard Model couplings, and thus an increase of a few GeV in the current lower bound on the Standard Model Higgs mass would rule out the model. The two heavier Higgs are both gauge-phobic, one decays almost entirely into b pairs and can be produced via gluon fusion while the other decays almost entirely into tau pairs but can't be easily produced.

description: Lorentz Invariance Violation (LIV) manifesting itself by energy dependent modification of standard relativistic dispersion relation has recently attracted a considerable attention. Ellis et al. previously investigated the energy dependent time offsets in different energy bands on a sample of gamma ray bursts and, assuming standard cosmological model, they found a weak indication for redshift dependence of time delays suggestive of LIV. Going beyond the $Λ$CDM cosmology we extend this analysis considering also four alternative models of dark energy (quintessence with constant and variable equation of state, Chaplygin gas and brane-world cosmology). It turns out that the effect noticed by Ellis et al. is also present in those models and is the strongest for quintessence with variable equation of state.

description: We study the properties of Brightest Cluster Galaxies (BCGs) drawn from a catalogue of more than 69000 clusters in the SDSS DR6 based on the adaptive matched filter technique (AMF, Szabo et al., 2010). Our sample consists of more than 14300 galaxies in the redshift range 0.1-0.3. We test the catalog by showing that it includes well-known BCGs which lie in the SDSS footprint. We characterize the BCGs in terms of r-band luminosities and optical colours as well as their trends with redshift. In particular, we define and study the fraction of blue BCGs, namely those that are likely to be missed by either colour-based cluster surveys and catalogues. Richer clusters tend to have brighter BCGs, however less dominant than in poorer systems. 4-9% of our BCGs are at least 0.3 mag bluer in the g-r colour than the red-sequence at their given redshift. Such a fraction decreases to 1-6% for clusters above a richness of 50, where 3% of the BCGs are 0.5 mag below the red-sequence. A preliminary morphological study suggests that the increase in the blue fraction at lower richnesses may have a non-negligible contribution from spiral galaxies. We show that a colour selection based on the g-r red-sequence or on a cut at colour u-r >2.2 can lead to missing the majority of such blue BCGs. We also extend the colour analysis to the UV range by cross-matching our catalogue with publicly available data from Galex GR4 and GR5. We show a clear correlation between offset from the optical red-sequence and the amount of UV-excess. Finally, we cross-matched our catalogue with the ACCEPT cluster sample (Cavagnolo et al., 2009), and find that blue BCGs tend to be in clusters with low entropy and short cooling times. That is, the blue light is presumably due to recent star formation associated to gas feeding by cooling flows. (abridged)

description: We show that $\ell_p$ norms are characterized as the unique norms which are both invariant under coordinate permutation and multiplicative with respect to tensor products. Similarly, the $L_p$ norms are the unique rearrangement-invariant norms on a probability space such that $\|X Y\|=\|X\|\cdot\|Y\|$ for every pair $X,Y$ of independent random variables. Our proof relies on Cramér's large deviation theorem.

Brain connectivity dynamics of reading and dyslexia : typical and perturbed reading networks in adults and children
Creators: name: Bedo, Nicolas
Publisher: name: University of British Columbia
Year: 2018

description: Developmental dyslexia is a language-based learning disability characterized by impaired reading speed and accuracy, poor spelling, and poor decoding abilities, despite normal intelligence. Neuroimaging investigations have identified brain regions critical for reading; few studies, however, have characterized how those regions interact to form networks and how those networks are perturbed in individuals with dyslexia. Advances in electroencephalography (EEG) analysis techniques now allow for intricate examination of these networks by focusing on individual frequency bands that comprise the brain signals. This study used EEG across several experiments to examine theta- and gamma-band connectivity patterns—first in the brains of adults, and then in dyslexic and typically-developing children during reading tasks. I investigated: 1) the ways in which the reading networks of typical and dyslexic readers differ, and 2) whether targeted reading interventions reduce these differences over time. Results show that dyslexic children generated greater occipito-temporal connectivity at critical time points in response to words and word-like stimuli, as well as increased engagement of higher-level language areas even for stimuli lacking linguistic content (e.g. consonant strings). After six months, the networks of dyslexic readers resembled those of their typically-developing counterparts for simple orthographic processing, but continued to utilize existing alternative pathways when engaging in higher-level language processes (e.g. phonology). This suggests that performance improvements in dyslexic readers are not necessarily related to changes to the typical left-lateralization of reading networks. These findings are in line with existing frameworks of dyslexia, and highlight the value of connectivity measures in understanding the neural underpinnings of word reading.

Subjects: subject: Computer Vision and Pattern Recognition (cs.CV)

description: Combining the properties of monovariate internal functions as proposed in Kolmogorov superimposition theorem, in tandem with the bounds wielded by the multivariate formulation of Chebyshev inequality, a hybrid model is presented, that decomposes images into homogeneous probabilistically bounded multivariate surfaces. Given an image, the model shows a novel way of working on reduced image representation while processing and capturing the interaction among the multidimensional information that describes the content of the same. Further, it tackles the practical issues of preventing leakage by bounding the growth of surface and reducing the problem sample size. The model if used, also sheds light on how the Chebyshev parameter relates to the number of pixels and the dimensionality of the feature space that associates with a pixel. Initial segmentation results on the Berkeley image segmentation benchmark indicate the effectiveness of the proposed decomposition algorithm.

description: The goal of this research was to study how fear-arousing misinformation (FAM) elicits a backfire effect of web add-on correction and whether situational fear and situational threat appraisals intervene in the relationship. The study featured an online experiment (N = 167) with a 2 (misinformation: fear-neutral vs. fear-arousal) × 2 (presence of correction: no correction vs. web add-on correction) between-group factorial design. Results suggest that web add-on correction was effective in decreasing situational susceptibility when fear-neutral misinformation was displayed (but not when FAM was presented) and that this susceptibility is positively associated with belief in misinformation. The findings from this research highlight that emotional-laden misinformation and perceived susceptibility are key drivers of nullifying correction effects, thereby providing insight into mapping out strategies for mitigating persuasive effects misinformation in risky situations.

description: Using density functional theory in a time dependent approach we determine the frequencies of the compressional modes of the normal phase of a Fermi gas at unitarity as a function of its polarization. Our energy functional accounts for the typical elastic deformations exhibited by Landau theory of Fermi liquids. The comparison with the available experiments is biased by important collisional effects affecting both the {\it in phase} and the {\it out of phase} oscillations even at the lowest temperatures. New experiments in the collisionless regime would provide a crucial test of the applicability of Landau theory to the dynamics of these strongly interacting normal Fermi gases.

Advanced network analysis of resting-state functional connectivity to probe executive function in Parkinson's Disease and Multiple Sclerosis
Creators: name: Lin, Sue-Jin
Publisher: name: University of British Columbia
Year: 2018

description: This thesis is to probe the systems-level neurobiological bases for executive function in patient populations overarchingly. We focus on two representative diseases, Parkinson’s Disease (PD), and Multiple Sclerosis (MS), as although they have different pathologies, patients often result in similar cognitive deficits. We examine resting-state fMRI data from both PD and MS subjects with novel methods in a network fashion. We employ advanced connectivity analyses to evaluate graph theoretical, static and dynamic resting-state functional connectivity (rsFC) measures. Multivariate statistical methods such as Canonical Correlate Analysis (CCA) and Multiset Canonical Correlate Analysis (MCCA) are used to robustly link rsFC and cognitive performance. PD data used in the thesis research include three cohorts: Parkinson’s Progression Markers Initiative (PPMI) and two research projects conducted at UBC (project name: BCT and GFM2). For MS, two cohorts are included: OPERA MS clinical trial and COGMS research project, which are both conducted at UBC. After a general introduction in the first chapter, in the second chapter we examine multivariate relations between demographic and cognitive profiles with CCA, showing that female gender is associated with better cognitive performance in both diseases possibly due to protective effects of estrogen. In chapter 3, we use correlation to assess functional connections. Both diseases have significantly altered interhemispheric connectivity, which is associated with altered cognitive performance in MS, but not PD. In chapter 4, we utilize graph theoretical approaches and find increased segregation of rsFC in PD, supporting a previously-proposed model of vulnerability of hubs in disease populations. In MS, higher modularity of the rsFC network is correlated with better executive skills. In chapter 5, we explore dynamic rsFC and discover that longer disease duration in MS is associated with decreased dynamic rsFC. In both populations, dynamic interhemispheric connectivity is robustly associated with cognitive abilities. In chapter 6, MCCA is applied to jointly explore the associations between dynamic and stationary rsFC, and behavioural measures. In MS, better executive functioning is supported by higher education, stronger and dynamic rsFC; in PD, better memory function is related to segregated brain networks and dynamics of interhemispheric connections. Chapter 7 summarizes and concludes these chapters.

description: The ability to make zero-shot predictions about the fitness consequences of protein sequence changes with pre-trained machine learning models enables many practical applications. Such models can be applied for downstream tasks like genetic variant interpretation and protein engineering without additional labeled data. The advent of capable protein structure prediction tools has led to the availability of orders of magnitude more precomputed predicted structures, giving rise to powerful structure-based fitness prediction models. Through our experiments, we assess several modeling choices for structure-based models and their effects on downstream fitness prediction. Zero-shot fitness prediction models can struggle to assess the fitness landscape within disordered regions of proteins, those that lack a fixed 3D structure. We confirm the importance of matching protein structures to fitness assays and find that predicted structures for disordered regions can be misleading and affect predictive performance. Lastly, we evaluate an additional structure-based model on the ProteinGym substitution benchmark and show that simple multi-modal ensembles are strong baselines.

description: We present new measurements of the temperature of the intergalactic medium (IGM) derived from the Lyman-alpha forest over 2.0 < z < 4.8. The small-scale structure in the forest of 61 high-resolution QSO spectra is quantified using a new statistic, the curvature, and the conversion to temperature calibrated using a suite of hydrodynamic simulations. At each redshift we focus on obtaining the temperature at an optimal overdensity probed by the Lyman-alpha forest, T(Delta), where the temperature is nearly a one-to-one function of the curvature regardless of the slope of the temperature-density relation. The median 2-sigma statistical uncertainty in these measurements is 8 per cent, though there may be comparable systematic errors due to the unknown amount of Jeans smoothing in the IGM. We use our T(Delta) results to infer the temperature at the mean density, T0. Even for a maximally steep temperature-density relation, T0 must increase from ~8000 K at z ~ 4.4 to >~12000 K at z ~ 2.8. This increase is not consistent with the monotonic decline in T0 expected in the absence of He II reionization. We therefore interpret the observed rise in temperature as evidence of He II reionization beginning at z >~ 4.4. The evolution of T0 is consistent with an end to He II reionization at z ~ 3, as suggested by opacity measurements of the He II Lyman-alpha forest, although the redshift at which T0 peaks will depend somewhat on the evolution of the temperature-density relation. These new temperature measurements suggest that the heat input due to the reionization of He II dominates the thermal balance of the IGM over an extended period with Delta_z >~ 1.

description: Few-layer graphene (FLG) has been predicted to exist in various crystallographic stacking sequences, which can strongly influence the electronic properties of FLG. We demonstrate an accurate and efficient method to characterize stacking order in FLG using the distinctive features of the Raman 2D-mode. Raman imaging allows us to visualize directly the spatial distribution of Bernal (ABA) and rhombohedral (ABC) stacking in tri- and tetra-layer graphene. We find that 15% of exfoliated graphene tri- and tetra-layers is comprised of micron-sized domains of rhombohedral stacking, rather than of usual Bernal stacking. These domains are stable and remain unchanged for temperatures exceeding $800^{\circ}$C.

Planetary nebulae abundances and stellar evolution II

description: Context: In recent years mid- and far infrared spectra of planetary nebulae have been analysed and lead to more accurate abundances. It may be expected that these better abundances lead to a better understanding of the evolution of these objects. Aims: The observed abundances in planetary nebulae are compared to those predicted by the models of Karakas (2003) in order to predict the progenitor masses of the various PNe used. The morphology of the PNe is included in the comparison. Since the central stars play an important role in the evolution, it is expected that this comparison will yield additional information about them. Methods: First the nitrogen/oxygen ratio is discussed with relation to the helium/hydrogen ratio. The progenitor mass for each PNe can be found by a comparison with the models of Karakas. Then the present luminosity of the central stars is determined in two ways: first by computing the central star effective temperature and radius, and second by computing the nebular luminosity from the hydrogen and helium lines. This luminosity is also a function of the initial mass so that these two values of initial mass can be compared. Results: Six of the seven bipolar nebulae can be identified as descendants of high mass stars (4Msun - 6Msun) while the seventh is ambiguous. Most of the elliptical PNe have central stars which descend from low initial mass stars, although there are a few caveats which are discussed. There is no observational evidence for a higher mass for central stars which have a high carbon/oxygen ratio. The evidence provided by the abundance comparison with the models of Karakas is consistent with the HR diagram to which it is compared. In the course of this discussion it is shown how `optically thin' nebulae can be separated from those which are 'optically thick'.

description: Patients with inflammatory bowel disease (IBD) are at increased risk of thrombotic events. Therapies for IBD have the potential to modulate this risk. The aims of this Evidence-Based Guideline were to summarize available evidence and to provide practical recommendations regarding epidemiological aspects, prevention and drug-related risks of venous and arterial thrombotic events in patients with IBD. A virtual meeting took place in May 2020 involving 14 international IBD experts and 3 thrombosis experts from 12 countries. Proposed statements were voted upon in an anonymous manner. Agreement was defined as at least 75% of participants voting as 'fully agree' or 'mostly agree' with each statement. For each statement, the level of evidence was graded according to the Scottish Intercollegiate Guidelines Network (SIGN) grading system. Consensus was reached for 19 statements. Patients with IBD harbour an increased risk of venous and arterial thrombotic events. Thromboprophylaxis is indicated during hospitalization of any cause in patients with IBD. Disease activity is a modifiable risk factor in patients with IBD, and physicians should aim to achieve deep remission to reduce the risk. Exposure to steroids should be limited. Antitumour necrosis factor agents might be associated with a reduced risk of thrombotic events.

description: Body temperature homeostasis is essential and reliant upon the integration of outputs from multiple classes of cooling- and warming-responsive cells. The computations that integrate these outputs are not understood. Here, we discover a set of warming cells (WCs) and show that the outputs of these WCs combine with previously described cooling cells (CCs) in a cross-inhibition computation to drive thermal homeostasis in larval Drosophila WCs and CCs detect temperature changes using overlapping combinations of ionotropic receptors: Ir68a, Ir93a, and Ir25a for WCs and Ir21a, Ir93a, and Ir25a for CCs. WCs mediate avoidance to warming while cross-inhibiting avoidance to cooling, and CCs mediate avoidance to cooling while cross-inhibiting avoidance to warming. Ambient temperature-dependent regulation of the strength of WC- and CC-mediated cross-inhibition keeps larvae near their homeostatic set point. Using neurophysiology, quantitative behavioral analysis, and connectomics, we demonstrate how flexible integration between warming and cooling pathways can orchestrate homeostatic thermoregulation.

description: We present molecular line observations, made with angular resolutions of ~20", toward the filamentary infrared dark cloud G34.43+0.24 using the APEX [CO(3-2), 13CO(3-2), C18O(3-2) and CS(7-6) transitions], Nobeyama 45 m [CS(2-1), SiO(2-1), C34S(2-1), HCO+(1-0), H13CO+(1-0) and CH3OH(2-1) transitions], and SEST [CS(2-1) and C18O(2-1) transitions] telescopes. We find that the spatial distribution of the molecular emission is similar to that of the dust continuum emission observed with 11" resolution showing a filamentary structure and four cores. The cores have local thermodynamic equilibrium masses ranging from 3.3x10^2 - 1.5x10^3 solar masses and virial masses from 1.1x10^3 - 1.5x10^3 solar masses, molecular hydrogen densities between 1.8x10^4 and 3.9x10^5 cm^{-3}, and column densities >2.0x10^{22} cm^{-2}; values characteristics of massive star forming cores. The 13CO(3-2) profile observed toward the most massive core reveals a blue profile indicating that the core is undergoing large-scale inward motion with an average infall velocity of 1.3 km/s and a mass infall rate of 1.8x10^{-3} solar masses per year. We report the discovery of a molecular outflow toward the northernmost core thought to be in a very early stage of evolution. We also detect the presence of high velocity gas toward each of the other three cores, giving support to the hypothesis that the excess 4.5 $μ$ emission ("green fuzzies") detected toward these cores is due to shocked gas. The molecular outflows are massive and energetic, with masses ranging from 25 -- 80 solar masses, momentum 2.3 - 6.9x10^2 \Msun km/s, and kinetic energies 1.1 - 3.6x10^3 \Msun km^2 s^{-2}; indicating that they are driven by luminous, high-mass young stellar objects.

description: Agricultural systems are currently experiencing a wave of new technological developments, which could lead to large and possibly disruptive changes in agricultural systems. So far, the adoption rates of new technologies have been highly variable, and attempts have been made to estimate adoption rates based on specific attributes of the technology and how it will be used, which can be difficult with new and emerging technology. An alternative approach is the Theory of Reasoned Action, published by Fishbein and Ajzen in 1975, which aims to explain how individuals will behave based on their existing attitudes and behavioural intentions and could be useful for examining the factors influencing adoption of future technologies. Current agricultural students are the farmers, researchers and rural professionals of the future. Their attitudes and beliefs towards technology will influence its integration into farming systems and how ethical concerns will have to be addressed. 300 current UK agricultural students participated in in an online survey; their perceptions around current and future agricultural technology developments were analysed using quantitative and qualitative methods. Results showed efficiency gains and improved management as the major perceived benefits of technology, while potential malfunction of and overreliance on technology were the main perceived risks.

description: Governments span generations, connecting the governed to their history and to their future through the continuous pursuit of civil peace and flourishing. A state’s constitution binds the government to this pursuit. Success in the endeavor is most importantly gauged by the actions of the government over time. The buildings that house the government have a role in articulating its purpose to public officials and citizens. By durable and contextually suitable design and by architectural expressions that incorporate the recognizable and time-honored typological symbols associated with edifices of its kind, a state’s capitol can project into the surrounding city fabric the worthy purpose of the government.
Resource versus ratio-dependent consumer-resource models: A Bayesian perspective

description: There is an ongoing debate in the literature regarding the appropriate mathematical description of consumer resource interactions, particularly with respect to the issue of resource vs. ratio-dependent functional response models. Early formulations of consumer-re source exploitation of the Lotka-Volterra type described predator consumption rates as linear functions of prey density (see Berryman 1992). This characterization has since been questioned by many researchers (e.g., Holling 1959, DeAngelis et al. 1975). Numerous consumer-resource functional response models have been proposed, each implying different system behaviors and stabilities. In a series of recent articles R. Arditi and colleagues have advocated a modification of these functional responses so that consumer exploitation of a resource is related to the ratio of the resource to the consumer (Arditi and Ginzburg 1989, Arditi et al. 1991, Arditi and Saiah 1992). This view has been challenged by Oksanen et al. (1992) who favor are source-dependent functional response. Diehl et al. (1993) have offered the perspective that simplified descriptions of consumer-resource dynamics are counter productive because they preclude a true mechanistic understanding of the complex interactions that occur. We argue that resource vs. ratio dependence should not be approached as a dichotomy, but rather as a continuum, and propose a Bayesian perspective as a useful context in which to view the issue. From this vantage ratio dependence can be a matter of degree, which varies among systems, and serves as a useful surrogate to characterize underlying mechanisms. Previous research has shown that resource vs. ratio dependence is difficult to ascertain from field data (Carpenter et al. 1994). This difficulty may, in part, result from spatial and temporal aggregation of the data such that resource/ratio dependence is in fact manifest at an intermediate level. We demonstrate the Bayesian approach with a simple ex ample, using time-series data from a mesocosm nutrient-enrichment experiment.
"We are not a conquered people" : expressions of resistance, resurgence, and reclamation through electric pow wow

description: This thesis examines the work of Indigenous DJ collective A Tribe Called Red, namely their reimagining of the contemporary pow wow. Dubbed “Electric Pow Wow,” the event showcases urban Indigenous culture, centered around music that layers elements of hip hop and electronic dance music with samples of First Nations vocals and drumming. Born out of the “Indigenous music renaissance,” A Tribe Called Red stands among a new generation of artists who are working alongside resistance movements like Idle No More in order to push back against colonial narratives of erasure and illuminate the voices of Indigenous communities the world over. Prioritizing contemporary Indigenous perspectives, this study seeks to engage with core themes of identity, community, representation, and decolonization, and discusses the essential role of musicians and culture-bearers within these spheres. Through an examination of A Tribe Called Red’s live shows, music videos, and social/political presence, I investigate Electric Pow Wow as both a physical and virtual gathering place where Indigenous identities are reclaimed, articulated, strengthened, and celebrated within broader movements of decolonization in North America and around the globe.
title: CeFF: A Frameword for Forensics Enabled Cloud Investigation

description: Today, cloud computing has developed a transformative model for the organization, business, governments that brings huge potentials and turn into popular for pay as you go, on-demand service, scalability and efficient services. However, cloud computing has made the concern for forensic data because of the architecture of cloud system is not measured appropriately. Due to the distributed nature of the cloud system, many aspects relating to the forensic investigation such as data collection, data storage, crime target, data violation are difficult to achieve. Investigating the incidents in the cloud environment is a challenging task because the forensics investigator still needs to relay on the third party such as cloud service provider for performing their investigation tasks. It makes the overall forensic process difficult to complete with a duration and presented it to the court. Recently, there are some cloud forensics studies to address the challenges such as evidence collection, data acquisition, identifying the incidents and so on. However, still, there is a research gap in terms of consistency of analysing forensic evidence from distributed environment and methodology to analyse the forensic data in the cloud.
This thesis contributes towards the direction of addressing the research gaps. In particular, this work proposes a forensic investigation framework CeFF: A framework for forensics enabled cloud investigation to investigate evidence in the cloud computing environment. The framework includes a set of concepts from organisational, technical and legal perspectives, which gives a holistic view of analysing cybercrime from organisation context where the crime has occurred through technical context and legal impact. The CeFF also includes a systematic process that uses the concept for performing the investigation. The cloud-enabled forensics framework meets all the forensics related requirement such as data collection, examination, presents the report, and identifies the potential risks that can consider while investigating the evidence in the cloud-computing environment. Finally, the proposed CeFF is applied to a real-life example to validate its applicability. The result shows that CeFF supports analysing the forensic data for a crime occurred in cloud-based system in a systematic way.

description: The novel coronavirus SARS-CoV-2 is the seventh identified human coronavirus. Understanding the extent of pre-existing immunity induced by seropositivity to endemic seasonal coronaviruses and the impact of cross-reactivity on COVID-19 disease progression remains a key research question in immunity to SARS-CoV-2 and the immunopathology of COVID-2019 disease. This paper describes a panel of lentiviral pseudotypes bearing the spike (S) proteins for each of the seven human coronaviruses (HCoVs), generated under similar conditions optimized for high titre production allowing a high-throughput investigation of antibody neutralization breadth. Optimal production conditions and most readily available permissive target cell lines were determined for spike-mediated entry by each HCoV pseudotype: SARS-CoV-1, SARS-CoV-2 and HCoV-NL63 best transduced HEK293T/17 cells transfected with ACE2 and TMPRSS2, HCoV-229E and MERS-CoV preferentially entered HUH7 cells, and CHO cells were most permissive for the seasonal betacoronavirus HCoV-HKU1. Entry of ACE2 using pseudotypes was enhanced by ACE2 and TMPRSS2 expression in target cells, whilst TMPRSS2 transfection rendered HEK293T/17 cells permissive for HCoV-HKU1 and HCoV-OC43 entry. Additionally, pseudotype viruses were produced bearing additional coronavirus surface proteins, including the SARS-CoV-2 Envelope (E) and Membrane (M) proteins and HCoV-OC43/HCoV-HKU1 Haemagglutinin-Esterase (HE) proteins. This panel of lentiviral pseudotypes provides a safe, rapidly quantifiable and high-throughput tool for serological comparison of pan-coronavirus neutralizing responses; this can be used to elucidate antibody dynamics against individual coronaviruses and the effects of antibody cross-reactivity on clinical outcome following natural infection or vaccination.
Generalized matching criterion for electrostatic ion solitary propagations in quasineutral magnetized plasmas

description: Based on the magnetohydrodynamics (MHD) model, an exact arbitrary-amplitude general solution is presented for oblique propagation of solitary excitations in two- and three-component quasineutral magnetoplasmas, adopting the standard pseudopotential approach. It is revealed that the necessary matching criterion of existence of such oblique nonlinear propagations in two and three-fluid magnetoplasmas share global features. These features are examined for the cases of electron-ion and electron-positron-ion magnetoplasmas with diverse equations of state. This study also reveals that for electron-ion magnetoplasmas with plasma-frequencies larger than the cyclotron-frequency ($B_0<0.137\sqrt{n_0}$) a critical-angle of $β_{cr}=\arccos{\left[B_0 /(0.137 \sqrt{n_0})\right]}$ exists, at which propagation of solitary excitation is not possible. Coriolis effect on allowed soliton matching condition in rotating magnetoplasmas is also considered as an extension to this work. Current investigation can have important implications for nonlinear wave dynamics in astrophysical as well as laboratory magnetoplasmas.
