description: We consider the finite temperature Casimir effect of a massive fermionic field confined between two parallel plates, with MIT bag boundary conditions on the plates. The background spacetime is $M^{p+1}\times T^q$ which has $q$ dimensions compactified to a torus. On the compact dimensions, the field is assumed to satisfy periodicity boundary conditions with arbitrary phases. Both the high temperature and the low temperature expansions of the Casimir free energy and the force are derived explicitly. It is found that the Casimir force acting on the plates is always attractive at any temperature regardless of the boundary conditions assumed on the compact torus. The asymptotic limits of the Casimir force in the small plate separation limit are also obtained.

description: We report the probable identification of the X-ray counterpart to the gamma-ray pulsar PSR J2021+4026 using imaging with the Chandra X-ray Observatory ACIS and timing analysis with the Fermi satellite. Given the statistical and systematic errors, the positions determined by both satellites are coincident. The X-ray source position is R.A. 20h21m30.733s, Decl. +40 deg 26 min 46.04sec (J2000) with an estimated uncertainty of 1.3 arsec combined statistical and systematic error. Moreover, both the X-ray to gamma-ray and the X-ray to optical flux ratios are sensible assuming a neutron star origin for the X-ray flux. The X-ray source has no cataloged infrared-to-visible counterpart and, through new observations, we set upper limits to its optical emission of i' >23.0 mag and r' > 25.2mag. The source exhibits an X-ray spectrum with most likely both a powerlaw and a thermal component. We also report on the X-ray and visible light properties of the 43 other sources detected in our Chandra observation.

Diffusion Scattering of Waves is a Model of Subquantum Level?

description: In the paper, we discuss the studies of mathematical models of diffusion scattering of waves in the phase space, and relation of these models with quantum mechanics. In the previous works it is shown that in these models of classical scattering process of waves, the quantum mechanical description arises as the asymptotics after a small time. In this respect, the proposed models can be considered as examples in which the quantum descriptions arise as approximate ones for certain hypothetical reality. The deviation between the proposed models and the quantum ones can arise, for example, for processes with rapidly changing potential function. Under its action the diffusion scattering process of waves will go out from the states described by quantum mechanics. In the paper it is shown that the proposed models of diffusion scattering of waves possess the property of gauge invariance. This implies that they are described similarly in all inertial coordinate systems, i.e., they are invariant under the Galileo transformations. We propose a program of further research.

Delayed and Sustained Remote Triggering of Small Earthquakes in the San Jacinto Fault Region by the 2014 Mw 7.2 Papanoa, Mexico Earthquake

description: We apply a move max matched-filter method to detect heightened seismicity triggered in the San Jacinto fault (SJF) zone, by the 2014 Mw 7.2 Papanoa, Mexico earthquake. The move max matched filter detects 5.4 and 1.7 times the number of earthquakes in the Southern California Seismic Network catalog and those detected by the matched-filter method, respectively. The seismicity rate increases significantly ~3.5 hr after the passage of the teleseismic waves and persists above the background level for about 1 week. This observation of delayed triggering may imply that dynamic stresses had initiated a time-dependent advance to failure or a secondary process. A highly active triggered patch is located ~10 km west of the SJF near Anza, on a previously unmapped fault. Focal mechanisms and a best fit plane suggest a normal fault perpendicular to the SJF. The unmapped fault may indicate higher seismic hazard in the surrounding areas if a large earthquake nucleated around the Anza seismic gap.
Using Balanced Scales to Address Acquiescent Response Style

description: Measurement scales are widely used for collecting survey data about latent constructs in the social sciences. These scales are composed of multiple items that measure a single latent construct through rating response scales. Ideally, higher scores derived from ratings of these items indicate higher locations on a continuum of the latent construct. Nonetheless, errors stemming from how respondents choose their responses may complicate this measurement and lead to erroneous conclusions. Rating response scales are particularly vulnerable to Acquiescent Response Style (ARS), respondents’ tendency to choose “agree” responses regardless of the content of the items. Even though ARS has been studied for over half a century, there is still little agreement on how to address it. Balanced scales, formed by mixing items written in opposite directions of a given latent construct, are a well-known method used to measure and correct for ARS. However, concerns have been raised about the measurement properties of balanced scales, making their use controversial. The goal of this dissertation was to provide an in-depth insight into the capability of balanced scales to not only measure ARS but also to correct for it. For this goal, this dissertation combined three studies. The first study investigated the effects of scale balancing under ARS on construct and convergent validity, reliability, and factor structure. The second study compared statistical methods to correct for ARS in computing scores of latent constructs using balanced scales. The third study empirically examined the differences in measurement properties of two wording strategies for drafting reverse-worded items for balanced scales. Findings from this research suggest that scale balancing alone is insufficient to mitigate ARS-associated error and that statistical correction methods also need to be applied. However, these findings also imply that simple correction methods, such as Ordinary Least Squares regression and Confirmatory Factor Analysis, that use balanced scales may reduce the effects of ARS on scale scores. Furthermore, this study indicates that wording strategies used to generate balanced scales resulted in similar measurement properties. While the best practice for balanced scales design is still to be confirmed, this dissertation suggests that balanced scales may be a useful tool to control for ARS in surveys.

Le lecteur trouvera, dans le présent ouvrage, un très large éventail des commentaires les plus intéressants sur l’œuvre d’Homère, principalement orientés vers le sens physique et théologique de ses poèmes.

En empruntant à Porphyre, pour intituler ce florilège, l’expression « questions homériques », nous entendons lui rendre son titre de noblesse. Il ne s’agit pas tant de savoir si l’Iliade et l’Odyssée sont l’œuvre d’un seul poète ou de plusieurs, ni si le nom d’Homère s’applique à un personnage historiquement existant ou non, que de percevoir l’intention de l’auteur dans tel vers ou tel passage.

description: The halos of galaxies preserve unique records of their formation histories. We carry out the first combined observational and theoretical study of phase-space halo substructure in an early-type galaxy: M87, the central galaxy in the Virgo cluster. We analyze an unprecedented wide-field, high-precision photometric and spectroscopic data set for 488 globular clusters (GCs), which includes new, large-radius Subaru/Suprime-Cam and Keck/DEIMOS observations. We find signatures of two substructures in position-velocity phase-space. One is a small, cold stream associated with a known stellar filament in the outer halo; the other is a large shell-like pattern in the inner halo that implies a massive, hitherto unrecognized accretion event. We perform extensive statistical tests and independent metallicity analyses to verify the presence and characterize the properties of these features, and to provide more general methodologies for future extragalactic studies of phase-space substructure. The cold outer stream is consistent with a dwarf galaxy accretion event, while for the inner shell there is tension between a low progenitor mass implied by the cold velocity dispersion, and a high mass from the large number of GCs, which might be resolved by a ~0.5 L* E/S0 progenitor. We also carry out proof-of-principle numerical simulations of the accretion of smaller galaxies in an M87-like gravitational potential. These produce analogous features to the observed substructures, which should have observable lifetimes of ~1 Gyr. The shell and stream GCs together support a scenario where the extended stellar envelope of M87 has been built up by a steady rain of material that continues until the present day. This phase-space method demonstrates unique potential for detailed tests of galaxy formation beyond the Local Group.

description: We investigate the dynamics of a single two-level atom, which interacts with pulses propagating in two spatial-modes (right and left) and frequency-continuum. Using Heisenberg equations of motion, we present the explicit analytical derivations and general formalisms for atomic excitation with two spatial-mode multi-photon pulses in both Fock state and coherent state. Based on those formalisms, we show that perfect atomic excitation by single photon Fock state pulse can only be realized when it is rising-exponentially shaped in the even-mode---a balanced superposition of the two spatial-modes. Single photon from single spatial-mode can only give half of the maximal atomic excitation probability. We also show that the maximum atomic excitation probability with multi-photon pulses in the even-mode is a monotonic function of the average photon number for coherent state, but not for Fock states. Furthermore, we demonstrate that the atomic dynamics can be controlled by the relative phase between the two counter-propagating coherent state pulses incident on the atom, which is not the case with two Fock state pulses.

Acoustic pressure modulation driven by spatially non-uniform flow

description: The recent identification of a modulation of acoustic waves that is driven by spatial velocity gradients, using acoustic black and white hole analogues [Schenke et al., J. Acoust. Soc. Am. 154 (2023), 781-791], has shed new light on the complex interplay of acoustic waves and non-uniform flows. According to the virtual acoustic black hole hypothesis, these findings should be applicable to acoustic waves propagating in non-uniform flows of arbitrary velocity. In this study, the propagation of acoustic waves in non-uniform flows is investigated by incorporating a leading-order model of the acoustic pressure modulation into a Lagrangian wave tracking algorithm. Using this numerical method, the acoustic pressure modulation is recovered accurately in non-uniform subsonic flows. This suggests that spatial velocity gradients drive acoustic pressure modulations in any non-uniform flow, which can, as shown here, be readily quantified.

description: Objective: The last decades have seen a surge of robots for physical training and work assistance. How to best control these interfaces is unknown, although arguably the interaction should be similar to human movement assistance. Methods: We compare the behaviour and assessment of subjects tracking a moving target with assistance from (i) trajectory guidance (as typically used in robots for physical training), (ii) a human partner, and (iii) the reactive robot partner of Takagi et al. Results: Trajectory guidance was recognised as robotic, while the robot partner was felt as human-like. However, trajectory guidance was preferred to assistance from a human partner, which was recognised as less predictable. The robot partner also was felt to be more predictable and helpful than a human partner, and was preferred. Conclusions: While subjects like to rely on predictable interaction, such as in trajectory guidance, the control reactivity of the robot partner is essential for perceiving an interaction as human-like.
The Unified Method: II NLS on the Half-Line with $t$-Periodic Boundary Conditions

description: Boundary value problems for integrable nonlinear evolution PDEs formulated on the half-line can be analyzed by the unified method introduced by one of the authors and used extensively in the literature. The implementation of this general method to this particular class of problems yields the solution in terms of the unique solution of a matrix Riemann-Hilbert problem formulated in the complex $k$-plane (the Fourier plane), which has a jump matrix with explicit $(x,t)$-dependence involving four scalar functions of $k$, called spectral functions. Two of these functions depend on the initial data, whereas the other two depend on all boundary values. The most difficult step of the new method is the characterization of the latter two spectral functions in terms of the given initial and boundary data, i.e. the elimination of the unknown boundary values. For certain boundary conditions, called linearizable, this can be achieved simply using algebraic manipulations. Here, we first present an effective characterization of the spectral functions in terms of the given initial and boundary data for the general case of non-linearizable boundary conditions. This characterization is based on the analysis of the so-called global relation and on the introduction of the so-called Gelfand-Levitan-Marchenko representations of the eigenfunctions defining the spectral functions. We then concentrate on the physically significant case of $t$-periodic Dirichlet boundary data. After presenting certain heuristic arguments which suggest that the Neumann boundary values become periodic as $t\to\infty$, we show that for the case of the NLS with a sine-wave as Dirichlet data, the asymptotics of the Neumann boundary values can be computed explicitly at least up to third order in a perturbative expansion and indeed at least up to this order are asymptotically periodic.

description: We examine some properties of stars evolving close to the classical Eddington limit for electron-scattering opacity, when these stars maintain a chemically homogeneous structure as a result of mixing and/or mass loss. We consider analytical relations and models computed with the Geneva code. Homologous, chemically homogeneous stars evolving with a constant Eddington factor obey a relation of the form mu^2 M = const. This applies, for example, to Wolf-Rayet (WR) stars in stages without hydrogen. The value of the constant may depend on the metallicity, initial mass, evolutionary stage, and physical processes included in the considered homologous evolutionary sequence. An average value of the constant between 20 and 40 in solar units is consistent with the masses of Galactic WR stars.

description: X-ray variability in cool stars can be indicative of coronal magnetic field changes and reconfiguration from a variety of phenomena, including flare events (typical timescales of minutes – hours), active-region evolution (hours – days – weeks), rotational modulation (hours – days – weeks), and activity cycles (years – decades). As part of the EXTraS project (Exploring the X-ray transient and variable sky - http://www.extras-fp7.eu/ ), we are performing a survey of ‘long-term’ X-ray variability using the ~decade-long public database of XMM-Newton observations. We are thus focussing here on timescales from ~a day to ~a decade, using average flux values from individual XMM-Newton observations. Though the resulting sampling is often highly non-uniform in time, the light-curves can provide valuable insights into the magnetic activity outside of shorter-term flaring episodes. We have taken a number of stellar samples (Hipparcos-Tycho, Simbad …) and are evaluating the statistical properties of the flux distributions, and comparing these across, for example spectral type, and with previously-published estimates. We are also examining the potential effects of flare events on the apparent long-term variability estimates. We give a preliminary report both on the overall variability distributions and extreme cases, distinguishing between serendipitously-observed stars (yielding, in some sense an unbiased sample) and XMM-Newton target objects (a number of them already reported by other authors).

description: Metadynamics is an established sampling method aimed at reconstructing the free-energy surface relative to a set of appropriately chosen collective variables. In standard metadynamics the free-energy surface is filled by the addition of Gaussian potentials of pre-assigned and typically diagonal covariance. Asymptotically the free-energy surface is proportional to the bias deposited. Here we consider the possibility of using Gaussians whose variance is adjusted on the fly to the local properties of the free-energy surface. We suggest two different prescriptions: one is based on the local diffusivity and the other on the local geometrical properties. We further examine the problem of extracting the free-energy surface when using adaptive Gaussians. We show that the standard relation between the bias and the free energy does not hold. In the limit of narrow Gaussians an explicit correction can be evaluated. In the general case we propose to use instead a relation between bias and free energy borrowed from umbrella sampling. This relation holds for all kinds of incrementally deposited bias. We illustrate on the case of alanine dipeptide the advantage of using adaptive Gaussians in conjunction with the new free-energy estimator both in terms of accuracy and speed of convergence.

description: We present preliminary results from a uniform, large-scale survey of X-ray flare emission from dM stars, and provide estimates of flare occurrence rates. The 3XMM Serendipitous Source Catalogue together with several dM-star catalogues (primarily SDSS and LAMOST) have been used as the basis for this survey of X-ray flares from dM stars. The 3XMM catalogue and its associated data products provide an excellent basis for a ~decade-long comprehensive and sensitive survey of stellar flares – both from targeted active stars and from those observed serendipitously in the half-degree diameter field-of-view of each observation. The standard 3XMM results and products have been augmented by the output of the EXTraS project (Exploring the X-ray transient and variable sky - http://www.extras-fp7.eu/ ). We present results from both target and serendipitous observations. The latter provide an unbiased (with respect to stellar activity) study of flare energetics and occurrence rates. We compare the dM-star X-ray flare rates with those for our previously published XMM/Tycho survey (Pye et al, 2015, A&A, 581, A28; which was weighted towards earlier-type, i.e. F – K, stars) and published values from optical-band surveys.
Neutralino dark matter in mSUGRA/CMSSM with a 125 GeV light Higgs scalar

description: The minimal supergravity (mSUGRA or CMSSM) model is an oft-used framework for exhibiting the properties of neutralino (WIMP) cold dark matter (CDM). However, the recent evidence from Atlas and CMS on a light Higgs scalar with mass m_h\simeq 125 GeV highly constrains the superparticle mass spectrum, which in turn constrains the neutralino annihilation mechanisms in the early universe. We find that stau and stop co-annihilation mechanisms -- already highly stressed by the latest Atlas/CMS results on SUSY searches -- are nearly eliminated if indeed the light Higgs scalar has mass m_h\simeq 125 GeV. Furthermore, neutralino annihilation via the A-resonance is essentially ruled out in mSUGRA so that it is exceedingly difficult to generate thermally-produced neutralino-only dark matter at the measured abundance. The remaining possibility lies in the focus-point region which now moves out to m_0\sim 10-20 TeV range due to the required large trilinear soft SUSY breaking term A_0. The remaining HB/FP region is more fine-tuned than before owing to the typically large top squark masses. We present updated direct and indirect detection rates for neutralino dark matter, and show that ton scale noble liquid detectors will either discover mixed higgsino CDM or essentially rule out thermally-produced neutralino-only CDM in the mSUGRA model.

description: All dark matter structures appear to follow a set of universalities, such as phase-space density or velocity anisotropy profiles, however, the origin of these universalities remains a mystery. Any equilibrated dark matter structure can be fully described by two functions, namely the radial and the tangential velocity distribution functions (VDF), and when we will understand these two then we will understand all the observed universalities. Here we demonstrate that if we know the radial VDF, then we can derive and understand the tangential VDF. This is based on simple dynamical arguments about properties of collisionless systems. We use a range of controlled numerical simulations to demonstrate the accuracy of this result. We therefore boil the question of the dark matter structural properties down to understanding the radial VDF.

description: We consider a relativistically moving blob consisting of an isotropic electron distribution that Compton-scatters photons from an external isotropic radiation field. We compute the resulting beaming pattern, i.e. the distribution of the scattered photons, in the blob frame as well as in the observer's frame by using the full Klein-Nishina cross section and the exact incident photon distribution. In the Thomson regime the comparison of our approach with Dermer 1995 results in concurrent characteristics but different absolute number of the scattered photons by a factor of f_corr = 3.09. Additionally, our calculation yields a slightly lower boost factor which varies the more from the corresponding value in Dermer 1995 the higher the spectral index p of the electron distribution gets.

description: The goal of this paper consists of developing a new (more physical and numerical in comparison with standard and non-standard analysis approaches) point of view on Calculus with functions assuming infinite and infinitesimal values. It uses recently introduced infinite and infinitesimal numbers being in accordance with the principle 'The part is less than the whole' observed in the physical world around us. These numbers have a strong practical advantage with respect to traditional approaches: they are representable at a new kind of a computer - the Infinity Computer - able to work numerically with all of them. An introduction to the theory of physical and mathematical continuity and differentiation (including subdifferentials) for functions assuming finite, infinite, and infinitesimal values over finite, infinite, and infinitesimal domains is developed in the paper. This theory allows one to work with derivatives that can assume not only finite but infinite and infinitesimal values, as well. It is emphasized that the newly introduced notion of the physical continuity allows one to see the same mathematical object as a continuous or a discrete one, in dependence on the wish of the researcher, i.e., as it happens in the physical world where the same object can be viewed as a continuous or a discrete in dependence on the instrument of the observation used by the researcher. Connections between pure mathematical concepts and their computational realizations are continuously emphasized through the text. Numerous examples are given.

description: NBody realizations of axisymmetric collisional galaxy cores (e.g. M32, M33, NGC205, Milky Way) with embedded growing black holes are presented. Stars which approach the disruption sphere are disrupted and accreted to the black hole. We measure the zone of influence of the black hole and disruption rates in relaxation time scales. We show that secular gravitational instabilities dominate the initial core dynamics, while the black hole is small and growing due to consumption of stars. Later, the black hole potential dominates the core, and loss cone theory can be applied. Our simulations show that central rotation in galaxies can not be neglected for relaxed systems, and compare and discuss our results with the standard theory of spherically symmetric systems.

description: Boundary value problems for integrable nonlinear evolution PDEs formulated on the finite interval can be analyzed by the unified method introduced by one of the authors and used extensively in the literature. The implementation of this general method to this particular class of problems yields the solution in terms of the unique solution of a matrix Riemann-Hilbert problem formulated in the complex $k$-plane (the Fourier plane), which has a jump matrix with explicit $(x,t)$-dependence involving six scalar functions of $k$, called spectral functions. Two of these functions depend on the initial data, whereas the other four depend on all boundary values. The most difficult step of the new method is the characterization of the latter four spectral functions in terms of the given initial and boundary data, i.e. the elimination of the unknown boundary values. Here, we present an effective characterization of the spectral functions in terms of the given initial and boundary data. We present two different characterizations of this problem. One is based on the analysis of the so-called global relation, on the analysis of the equations obtained from the global relation via certain transformations leaving the dispersion relation of the associated linearized PDE invariant, and on the computation of the large $k$ asymptotics of the eigenfunctions defining the relevant spectral functions. The other is based on the analysis of the global relation and on the introduction of the so-called Gelfand-Levitan-Marchenko representations of the eigenfunctions defining the relevant spectral functions. We also show that these two different characterizations are equivalent and that in the limit when the length of the interval tends to infinity, the relevant formulas reduce to the analogous formulas obtained recently for the case of boundary value problems formulated on the half-line.

description: Superflares are flares that release total energy 10-104 times greater than that of the biggest solar flares (~1032 erg). Recent Kepler-space-telescope observations found more than 1000 superflares on a few hundred solar-type stars (Maehara et al. 2012, Nature; Shibayama et al. 2013, ApJS, Maehara et al. 2015 EPS). Such superflare stars show quasi-periodic brightness variations with the typical period of from one to a few tens of days. Such variations are thought to be caused by the rotation of the star with large starspots (Notsu et al. 2013, ApJ). However,

spectroscopic observations are needed in order to confirm whether the variation is really due to the rotation and whether superflares can occur on ordinary single stars similar to our Sun.

Then we have carried out spectroscopic observations for 50 solar-type superflare stars with Subaru/HDS (Notsu et al. 2015a&b, PASJ). As a result, more than half (34 stars) of the target stars show no evidence of binarity, and the atmospheric parameters of these stars are in the range of solar-type stars.

The detailed analyses for these 34 stars show that (1) the projected rotational velocities (v sin i) are consistent with the rotational velocities estimated from the brightness variations, (2) there is a correlation between the brightness variation amplitude and the intensity of Ca II IR triplet line. These results support that the brightness variation discussed above is explained by the rotation of a star with large starspots.

description: Starting with next-generation experiments, flavor physics fully enters the era of precision measurements. The focus shifts from testing the Standard Model to finding and characterizing new physics contributions. We review the opportunities offered by future flavor experiments, discussing the expected sensitivities of the most important measurements. We also present some examples of measurable deviations from the Standard Model in the flavor sector generated in a selection of new physics models, demonstrating the major contribution that precision flavor physics could give to the effort of going beyond the Standard Model.

H2020

description: Collaborative grant proposals are notoriously difficult to write. The EC selection process is very competitive, often retaining only proposals over 14 (out of 15) for funding. In this context, the lack of convincing open access strategy can lead the reviewer to flag a shortcoming and remove 0.5 point, which may well be the difference between a funded and unfunded proposal! It is not sufficient to write a paragraph repeating the open access requirements of Horizon 2020. You must also provide evidence to the reviewers that you have taken steps to implement these requirements in the dissemination plan (i.e. section 2) and the project plan (i.e. section 3). Failing to do so may have devastating effects in evaluations (in particular for Innovation Actions where section 2 has a 1.5x weight in the scoring formula). Common mistakes are to forget publishing budgets (for gold access) or to keep embargo periods which are too long (for green access). Experienced evaluators will also look for implementation details on your publication repository, and how it will integrate with search tools and social media tools. After all, it is not sufficient to deposit your publications in a repository, you must also ensure they are easily discoverable.
Sodium Channel Scn8a as a Target for Antiepileptic Therapy

description: The voltage-gated sodium channel Nav1.6 is a key regulator of neuronal excitability. Gain-of-function variants of SCN8A, the gene encoding Nav1.6, cause developmental and epileptic encephalopathy (DEE). SCN8A-DEE is characterized by drug-resistant seizures, movement disorders, and intellectual disability. We hypothesized that reducing expression of SCN8A would compensate for gain-of-function mutations. We developed an antisense oligonucleotide (ASO) that reduces expression of mouse Scn8a transcript. In SCN8A-DEE mice, neonatal administration of the Scn8a ASO delayed seizure onset and prolonged lifespan. However, people with SCN8A-DEE can only be treated after they begin to have seizures and receive a diagnosis. I therefore also administered the Scn8a ASO after the onset of seizures. The ASO reduced seizure frequency and prolonged survival from less than two months to more than one year after seizure onset. Due to its important role in the generation of action potentials, we hypothesized that reducing SCN8A expression could also be therapeutic in epilepsy caused by mutation of other genes. I administered the Scn8a ASO to epilepsy models caused by mutation of the sodium channel gene Scn1a, the potassium channel genes Kcna1 and Kcnq2, and the synaptic protein LGI1. The Scn8a ASO prolonged survival in all four models. Notably, the Scn1a mutant mice were completely rescued by a single, neonatal dose. I also tested reduction of potassium channel gene Kcnt1 in Scn1a and Scn8a mutants. The Kcnt1 ASO significantly prolonged survival of both models, though to a lesser extent than the Scn8a ASO. These results suggest that targeting key ion channel genes, including Scn8a and Kcnt1, may be a generalizable treatment for epilepsies of diverse etiologies. Despite the prominent role of ion channel genes in causing epilepsy, little is known about the transcriptional consequences of ion channel mutations. I performed single-nucleus RNA-sequencing on the hippocampus of Scn8a mutant mice. Before the onset of seizures, I detected few transcriptional changes within any cell type. After ten weeks of chronic seizures, dentate gyrus granule cells exhibited the most transcriptional changes, suggesting that seizures may specifically affect this cell type. I also detected expression of the voltage-gated sodium channels in oligodendrocyte precursor cells and a possible increase in the number of hippocampal oligodendrocytes in the Scn8a mutant mice, which may point to a role for sodium channels in oligodendrocyte differentiation. My results suggest that oligodendrocytes and dentate gyrus granule cells may play a role in the pathology of SCN8A-DEE.
