Genetic studies of the host-parasite relationship between Ustilago hordei and Hordeum vulgare
Creators: name: Ebba, Tadessa
Publisher: name: University of British Columbia
Year: 2010

description: Genetic studies were carried out on the fungal parasite Ustilago hordei (Pers.) Lagerh. and on its host, Hordeum vulgave L. (cultivated barley). In these studies of the host-parasite relationship, special emphasis was placed on the genetic investigation of the pathogenicity. The thesis is divided into four parts. Part I deals with multial1 elism of genes for virulence (v-genes) in the parasite, and demonstrated that four different levels of virulence (obtained on the barley cultivar Trebi) are controlled by alternative alleles at a single genetic locus in the parasite. This is the first demonstrated example of a series of multiple alleles determining different levels of virulence. Part II concerns the identification and characterization of v-genes in U. hordei and of resistance genes (R-genes) in H. vulgave. Three v-genes (two of them new, one of them previously known) were identified. It was shown that the previously identified gene was expressed either as a dominant or a recessive, dependingoon the conditions under which it was tested, and that the newly-identified genes were both recessive. Cultures possessing the newly-discovered v-genes were used in identifying two new R-genes in the barley host. A study of interactions involving the newly discovered v- and R-genes led to the conclusion that these interactions have their basis in gene-for-gene relationships. Part III deals with the synthesis of a complex biotype of u. hordei possessing v-genes at two genetic loci. Disease reaction obtained with this complex biotype were compared both qualitatively and quantitatively with those obtained with the simpler, parental biotypes. In tests on certain cultivars the complex biotype produced either the same or higher levels of disease reaction. Because the new biotype has ah extended host range it is considered that under certain conditions it would be comparatively more fit than either of the parental biotypes from which it was derived. Part IV of the thesis concerns the effects of nutritional deficiency on the action of v-genes. Dikaryons which were homozygous for arg, ad or met were in all cases non-pathogenic; for those which were homozygous for pdx, pathogenicity was unaffected. For dikaryons which were heterozygous for one or more nutritional deficiences, pathogenicity was either unimpaired or reduced, depending on the combination (deficiency: virulence gene: host cultivar) which was tested. It was concluded that the specificity of pathogen biotypes was not determined by the availability or non-availability of specific nutritional factors. However, the effects were not entirely non-specific, since changes in levels of virulence were shown only in certain tests.

description: In this work we obtain a new criterion to establish ergodicity and non-uniform hyperbolicity of smooth measures of diffeomorphisms. This method allows us to give a more accurate description of certain ergodic components. The use of this criterion in combination with topological devices such as blenders lets us obtain global ergodicity and abundance of non-zero Lyapunov exponents in some contexts. In the partial hyperbolicity context, we obtain that stably ergodic diffeomorphisms are C^1-dense among volume preserving partially hyperbolic diffeomorphisms with two-dimensional center bundle. This is motivated by a well known conjecture of C. Pugh and M. Shub.

New Numerical Methods to Evaluate Homogeneous Solutions of the Teukolsky Equation II. Solutions of the Continued Fraction Equation
Creators: name: Fujita, Ryuichi

Year: 2009
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: We investigate the solution of the continued fraction equation by which we determine "the renormalized angular momentum parameter", $ν$, in the formalism developed by Leaver and Mano, Suzuki, and Takasugi. In this formalism, we describe the homogeneous solutions of the radial Teukolsky equation, which is the basic equation of the black hole perturbation formalism. We find that, contrary to the assumption made in previous works, the solution, $ν$, becomes complex valued as $ω$ (the angular frequency) becomes large for each $l$ and $m$ (the degree and order of the spin-weighted spheroidal harmonics). We compare the power radiated by gravitational waves from a particle in a circular orbit in the equatorial plane around a Kerr black hole in two ways, one using the Mano-Suzuki-Takasugi formalism with complex $ν$ and the other using a direct numerical integration method. We find that the two methods produce consistent results. These facts prove the validity of using complex solutions to determine the homogeneous solutions of the Teukolsky equation.

description: A detailed understanding of the different mechanisms being responsible for terahertz (THz) emission in ferromagnetic (FM) materials will aid in designing efficient THz emitters. In this report, we present direct evidence of THz emission from single layer Co$_{0.4}$Fe$_{0.4}$B$_{0.2}$ (CoFeB) FM thin films. The dominant mechanism being responsible for the THz emission is the anomalous Hall effect (AHE), which is an effect of a net backflow current in the FM layer created by the spin-polarized current reflected at the interfaces of the FM layer. The THz emission from the AHE-based CoFeB emitter is optimized by varying its thickness, orientation, and pump fluence of the laser beam. Results from electrical transport measurements show that skew scattering of charge carriers is responsible for the THz emission in the CoFeB AHE-based THz emitter.

We propose a scheme to add a dark matter sector to quiver gauge theories with metastable supersymmetry breaking. We discuss the embedding of such scheme in string theory and we describe the dark matter sector in terms of D7 flavour branes. We explore the phenomenology in various regions of the parameters.

description: Modern spectroscopic databases provide a wealth of information about the physical processes and environments associated with astrophysical populations. Techniques such as blind source separation (BSS), in which sets of spectra are decomposed into a number of components, offer the prospect of identifying the signatures of the underlying physical emission processes. Principle Component Analysis (PCA) has been applied with some success but is severely limited by the inherent orthogonality restriction that the components must satisfy. Non-negative matrix factorisation (NMF) is a relatively new BSS technique that incorporates a non-negativity constraint on its components. In this respect, the resulting components may more closely reflect the physical emission signatures than is the case using PCA. We discuss some of the considerations that must be made when applying NMF and, through its application to the quasar spectra in the Sloan Digital Sky Survey (SDSS) DR6, we show that NMF is a fast method for generating compact and accurate reconstructions of the spectra. The ability to reconstruct spectra accurately has numerous astrophysical applications. Combined with improved SDSS redshifts, we apply NMF to the problem of defining robust continua for quasars that exhibit strong broad absorption line (BAL) systems. The resulting catalogue of SDSS DR6 BAL quasars will be the largest available. Importantly, the NMF approach allows quantitative error estimates to be derived for the Balnicity Indices as a function of key astrophysical and observational parameters, such as the quasar redshifts and the signal-to-noise ratio of the spectra.

Computation of forces and stresses in solids: Towards accurate structural optimization with auxiliary-field quantum Monte Carlo
Creators: name: Chen, Siyuan

Year: 2023
Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: The accurate computation of forces and other energy derivatives has been a long-standing challenge for quantum Monte Carlo methods. A number of technical obstacles contribute to this challenge. We discuss how these obstacles can be removed with the auxiliary-field quantum Monte Carlo (AFQMC) approach. AFQMC is a general, high-accuracy, many-body total-energy method for molecules and solids. The implementation of back-propagation for pure estimators allows direct calculation of gradients of the energy via the Hellmann-Feynman theorem. A planewave basis with norm-conserving pseudopotentials is used for the study of periodic bulk materials. Completeness of the planewave basis minimizes the effect of so-called Pulay terms. The ionic pseudopotentials, which can be incorporated in AFQMC in exactly the same manner as in standard independent-electron methods, regulate the force and stress estimators and eliminate any potential divergence of the Monte Carlo variances. The resulting approach allows applications of full geometry optimizations in bulk materials. It also paves the way for many-body computations of the phonon spectrum in solids.

description: We use deep images taken with the Advanced Camera for Surveys on board the Hubble Space Telescope of the disk galaxy NGC 891, to search for globular cluster candidates. This galaxy has long been considered to be a close analog in size and structure to the Milky Way and is nearly edge-on, facilitating studies of its halo population. These extraplanar ACS images, originally intended to study the halo field-star populations, reach deep enough to reveal even the faintest globular clusters that would be similar to those in the Milky Way. From the three pointings we have identified a total of 43 candidates after culling by object morphology, magnitude, and colour. We present (V,I) photometry for all of these, along with measurements of their effective radius and ellipticity. The 16 highest-rank candidates within the whole sample are found to fall in very much the same regions of parameter space occupied by the classic Milky Way globular clusters. Our provisional conclusion from this survey is that the total globular cluster population in NGC 891 as a whole may be almost as large as that of the Milky Way.

Consumer spatial behaviour and its relation to social class and family status in metropolitan Vancouver, Canada
Creators: name: Gayler, Hugh James
Publisher: name: University of British Columbia
Year: 2010

description: This study is concerned with the relationship between consumers' social class and family status characteristics and some spatial aspects of their shopping behaviour. In the past much of our understanding of how consumers behave spatially has been derived from studies of retail structure, and thus it has to be assumed that consumers behave in the same fashion; and where studies have looked at variations in behaviour they have concentrated on differences in retail demands or differences in the single, personal attributes (e.g. income or ethnic origin) which influence behaviour. Many of these personal attributes are interrelated, and in this study two such interrelationships are identified - social class and family status. A sample survey of consumers was undertaken in Metropolitan Vancouver, Canada; and using factor analysis it is possible to identify, and measure consumers according to, three dimensions (or interrelationships) among the socio-economic and demographic attributes asked for in the survey - social class and older and younger family status (two similar dimensions result from respondents being asked to identify their children by age group). Social class and family status are then related to two aspects of consumer spatial behaviour - travel behaviour, and in particular the distance and frequency travelled to shop for various goods and secondly the specific department store and its location chosen by the consumer. It is found that the higher the social class group, the greater the frequency shopping goods were purchased and the greater the distance travelled for groceries and dress. But for goods required less frequently and/or lacking a specialty nature (furniture, appliances and footwear) the differences in distance are not significant. On the family status dimension the low group (small families, invariably older and without children) often travel significantly shorter distances than other groups; the former reside mostly in the older areas, close to major shopping centres, and/or tend to shop at the nearest centre. Department-store preference is found to vary according to area. A significant polarisation of preference by social class is seen in downtown Vancouver, but in the outer suburbs, where the same firm has decentralised to widely differing social areas, similar allegiances are not found. Different department-store firms do not attract one particular family status group more than another. Differences are, however, related to geographic location with the downtown Vancouver and suburban stores attracting a significantly higher proportion of low and medium-high group consumers respectively.
The Scope of Free Inquiry According to the Vīmaṃsaka - sutta and its Madhyama - āgama Parallel

Year: 2010

description: The theme of the present article is the scope of free inquiry from the perspective of the Vīmaṃsaka-sutta of the Pāli Majjhima-nikāya and its counterpart in the Madhyama-āgama, preserved in Chinese translation. In these two specimens from the corpus of early Buddhist discourses, a prospective disciple is encouraged to investigate whether the Buddha’s claim to being a fully awakened teacher is justified. My presentation is based on an annotated translation of the Madhyama-āgama discourse, which is followed by a comparative study of the two versions and an evaluation of the significance of their presentation. My frame of reference in the present article is that of the thought-world of the early Buddhist discourses themselves, which for the most part can be considered representative of Buddhism in its pre-sectarian stage. This thought-world forms my point of departure in an attempt to illustrate the message these two parallel discourses convey on the theme of free inquiry in relation to one’s own teacher.

In this paper, we prove the global well-posedness for the compressible Navier-Stokes equations in the critical functional framework with the initial data close to a stable equilibrium. Especially, this result allows us to construct global solutions for the highly oscillating initial velocity. The proof relies on a new estimate for the hyperbolic/parabolic system with convection terms.

description: Within the context of local type IIB models arising from branes at toric Calabi-Yau singularities, we present a systematic way of joining any number of desired sectors into a consistent theory. The different sectors interact via massive messengers with masses controlled by tunable parameters. We apply this method to a toy model of the minimal supersymmetric standard model (MSSM) interacting via gauge mediation with a metastable supersymmetry breaking sector and an interacting dark matter sector. We discuss how a mirror procedure can be applied in the type IIA case, allowing us to join certain intersecting brane configurations through massive mediators.

The general problem in relation to which takes the form of educational research is that of rational control of the practices of education.

description: We consider the linear stability to three-dimensional perturbations of two-dimensional nonlinear magnetohydrodynamic basic states obtained from a specified forcing function in the presence of an imposed initially uniform magnetic field of strength $B_0$. The forcing is chosen such that it drives the CP flow of Galloway & Proctor (1992) when $B_0=0$. We first examine the properties of these basic states and their dependence on $B_0$ and on the magnetic Reynolds number $Rm$. The linear stability of these states is then investigated. It is found that at a given $Rm$ the presence of a background field is stabilising. The results also allow us to speculate that at a fixed value of $B_0$ the growth of the unstable perturbations is `fast', in the sense that the growth rate becomes independent of $Rm$ as $Rm \to \infty$.

Il Rigestum comunis Albe: la struttura di un liber iurium dal progetto originario alla fisionomia attuale

Publisher: name: Scrineum Rivista
Year: 2013
Subjects: diplomatics; Alba; liber iurium

description: The Rigestum comunis Albe is one of the earliest libri iurium in Piemonte and it has been used for a lot of papers about history and diplomatics; nevertheless, after the publication of the critical edition (1903) the codex was lost. Its founding, in 2003, allowed to analyse the book's structure, to reconstruct its original appearance, to trace the events of its life, so that the liber is not only the case of the sources for the history of the town, but also the protagonist of its own history. The first part (1215) is a faithful reproduction of the whole content of civic archive; after that, periodical updates have been added. Moreover, the scribes used to record on its pages also different kinds of documents, such as banishment lists or statutes’ articles. The form and content analysis of the unities composing the liber let us understand that, in comparison to the orginal project, both their sequence and their number have changed. The use of keeping fascicles unbound, so to make them easier to use in communal offices, was often the cause of their misplacing: because of that, they have been bound in the wrong order and material that was not part of the book has been included. It is likely that there have been some losses, but they are impossible to quantify. So we see a picture of the Rigestum which is different from today’s, but the constant element is the book’s identity: although in changed conditions, it succeedes in meeting the communal records’ conservation needs that led to its drafting.

description: We present low-frequency observations starting from ~150 MHz with the Giant Metrewave Radio Telescope (GMRT), and high-frequency observations with the Very Large Array (VLA) of two large radio galaxies 3C46 and 3C452. These observations were made with the objectives of estimating their spectral ages and examining any evidence of diffuse extended emission at low radio frequencies due to an earlier cycle of activity. While no evidence of extended emission due to an earlier cycle of activity has been found, the spectral ages have been estimated to be ~15 and 27 Myr for the oldest relativistic plasma seen in the regions close to the cores for 3C46 and 3C452 respectively. The spectra in the vicinity of the hotspots are consistent with a straight spectrum with injection spectral indices of ~1.0 and 0.78 respectively, somewhat steeper than theoretical expectations.

description: We have studied the contribution of higher order corrections of the flavor symmetry breaking in the $A_4$ seesaw model with the supersymmetry. Taking account of possible higher dimensional mass operators, we predict the deviation from the tri-bimaximal lepton mixing for both normal hierarchy and inverted hierarchy of neutrino masses. We have found that the value of $\sin^2 2θ_{23}$ is larger than 0.96 and the upper bound of $\sin^2θ_{13}$ is 0.01. We have also examined the flavor changing neutral current of leptons from the soft SUSY breaking in slepton masses and A-terms within the framework of supergravity theory. Those magnitudes are enough suppressed to be consistent with experimental constraints.

description: Multi-wavelength observations of an M 2.0 flare event on 2000 March 23 in NOAA active region 8910 provide us a good chance to study the detailed structure and dynamics of the magnetic reconnection region. In the process of the flare, extreme ultraviolet (EUV) loops displayed two times of sideward motions upon a loop-top hard X-ray source with average velocities of 75 and 25.6 km/s, respectively. We consider these two motions to be the observational evidence of reconnection inflow, and find an X-shaped structure upon the post-flare loops during the period of the second motion. Two separations of the flare ribbons are associated with these two sideward motions, with average velocities of 3.3 and 1.3 km/s, separately. Using the observation of photospheric magnetic field, the velocities of the sideward motions and the separations, we deduce the corresponding coronal magnetic field strength to be about 13.2-15.2 G, and estimate the reconnection rates to be 0.05 and 0.02 for these two magnetic reconnection processes, respectively. We also observe motions of bright points upward and downward along the EUV loops with velocities ranging from 45.4 to 556.7 km/s. A cloud of bright material flowing outward from the loop-top hard X-ray source with an average velocity of 51 km/s in the process of the flare may be accelerated by the tension force of the newly reconnected magnetic field lines. All the observations can be explained by schematic diagrams of magnetic reconnection.

description: It has recently been shown that by measuring the transverse polarization of the final particles in the LFV processes $μ\to eγ$, $μ\to eee$ and $μN\to e N$, one can derive information on the CP-violating phases of the underlying theory. We derive formulas for the transverse polarization of the final particles in terms of the couplings of the effective potential leading to these processes. We then study the dependence of the polarizations of $e$ and $γ$ in the $μ\to e γ$ and $μN \to e N$ on the parameters of the Minimal Supersymmetric Standard Model (MSSM). We show that combining the information on various observables in the $μ\to eγ$ and $μN\to e N$ search experiments with the information on the electric dipole moment of the electron can help us to solve the degeneracies in parameter space and to determine the values of certain phases.

description: We present the STAR preliminary results on mid-rapidity and low transverse momentum mean, standard deviation, skewness, and kurtosis of net-charge and net-proton distributions in Au+Au and Cu+Cu collisions at $\sqrt{s_{NN}}$ = 200 GeV for various collision centralities. All the measured high moments of these distributions can be scaled by the number of participating nucleons, consistent with the soft process emissions. The ratios of fourth to second order cumulants of both the net-charge and net-proton distributions are consistent with models without QCD critical point.

description: Optical single-short measurement of the cross-correlation function between periodic sequences is demonstrated. The sequences are encoded into the broadband ultrashort phase-shaped pulses which are mixed in the nonlinear medium with additional amplitude-shaped narrowband pulse. The spectrum of the resulted four wave mixing signal is measured to provide the cross-correlation function. The high contrast between the values of cross-correlation and auto-correlation (the latter includes also the information of the sequence period) has potential to be employed in the optical implementation of CDMA communication protocol.

description: AIMS. Several authors have claimed to detect a significant cross-correlation between microwave WMAP anisotropies and the SDSS galaxy distribution. We repeat these analyses to determine the different cross-correlation uncertainties caused by re-sampling errors and field-to-field fluctuations. The first type of error concerns overlapping sky regions, while the second type concerns non-overlapping sky regions. METHODS. To measure the re-sampling errors, we use bootstrap and jack-knife techniques. For the field-to-field fluctuations, we use three methods: 1) evaluation of the dispersion in the cross-correlation when correlating separated regions of WMAP with the original region of SDSS; 2) use of mock Monte Carlo WMAP maps; 3) a new method (developed in this article), which measures the error as a function of the integral of the product of the self-correlations for each map. RESULTS. The average cross-correlation for b>30 deg. is significantly stronger than the re-sampling errors--both the jack-knife and bootstrap techniques provide similar results--but it is of the order of the field-to-field fluctuations. This is confirmed by the cross-correlation between anisotropies and galaxies in more than the half of the sample being null within re-sampling errors. CONCLUSIONS. Re-sampling methods underestimate the errors. Field-to-field fluctuations dominate the detected signals. The ratio of signal to re-sampling errors is larger than unity in a way that strongly depends on the selected sky region. We therefore conclude that there is no evidence yet of a significant detection of the integrated Sachs-Wolfe (ISW) effect. Hence, the value of Omega_Λ~ 0.8 obtained by the authors who assumed they were observing the ISW effect would appear to have originated from noise analysis

Spontaneous violation of chiral symmetry in QCD vacuum is the origin of baryon masses and determines baryon magnetic moments and their other static properties

description: A short review is presented of the spontaneous violation of chiral symmetry in QCD vacuum. It is demonstrated, that this phenomenon is the origin of baryon masses in QCD. The value of nucleon mass is calculated as well as the masses of hyperons and some baryonic resonances and expressed mainly through the values of quark condensates -- $<0\mid \bar{q} q \mid 0>, ~q=u,d,s$ -- the vacuum expectation values (v.e.v.) of quark field. The concept of vacuum expectation values induced by external fields is introduced. It is demonstrated that such v.e.v. induced by static electromagnetic field results in quark condensate magnetic susceptibility, which plays the main role in determination of baryon magnetic moments. The magnetic moments of proton, neutron and hyperons are calculated. The results of calculation of baryon octet $β$-decay constants are also presented.

An analytic probability density function for partially premixed flames with detailed chemistry

description: Laminar premixed flame profiles of methane/air free flames and strained flames at different fuel/air ratios and strain rates are analysed using detailed chemistry with Lewis numbers equal to one. It is shown that the detailed chemistry flame profiles of progress variables CO2+CO and H2O+H2 in canonically stretched coordinates can be fitted accurately by a slight generalization of recently proposed analytical presumed flame profiles over a wide range of fuel/air ratios through adaptation of a single model parameter. Strained flame profiles can be reproduced using an additional linear coordinate transformation, emulating the compression of the preheat zone by strain as predicted by premixed flame theory. The model parameter can alternatively be determined using only the laminar flame speeds and the fully burnt temperatures from the laminar flame calculations. The stretch factor of the coordinate transformation is proportional to cp/lambda, which drops by factor up to 4 across the laminar flame. It is shown how the non-constant cp/lambda modifies the laminar flame \textcolor{black}{probability density function (pdf)}, a polynomial fit to cp/lambda as function of progress variable allows analytical results for the laminar flame pdf, the mean value of progress variable and of the reaction source term. An analytic pdf for partially premixed flames is proposed based on Bayes theorem as a combination of a beta pdf for the mixture fraction and the laminar flame pdf's evaluated at the respective fuel/air ratio.

description: Social units, such as households and schools, can play an important role in controlling epidemic outbreaks. In this work, we study an epidemic model with a prompt quarantine measure on networks with cliques (a $clique$ is a fully connected subgraph representing a social unit). According to this strategy, newly infected individuals are detected and quarantined (along with their close contacts) with probability $f$. Numerical simulations reveal that epidemic outbreaks in networks with cliques are abruptly suppressed at a transition point $f_c$. However, small outbreaks show features of a second-order phase transition around $f_c$. Therefore, our model can exhibit properties of both discontinuous and continuous phase transitions. Next, we show analytically that the probability of small outbreaks goes continuously to 1 at $f_c$ in the thermodynamic limit. Finally, we find that our model exhibits a backward bifurcation phenomenon.

agriculture development policy

description: This strong correlation between agriculture and climate change has led to the emergence of climate-smart agriculture (CSA) that seeks to balance agricultural productivity within the bounds of our climate. The CSV approach is participatory research for development approach that serve as testing ground for best context-specific CSA technologies and practices. International organizations have identified scaling of agricultural innovations as a priority agenda. In 2015, CGIAR-CCAFS began expanding the CSV approach in Southeast Asia with the establishment of seven CSVs in the region. Through the efforts of various partners, these CSVs have grown to 90 CSVs. This paper is presented as synthesis of the diverse experiences of the CSVs in Southeast Asia. The authors have reviewed key publications generated since 2015 in order to draw highlights and key lessons on scaling CSA via the CSV approach. The pathways of scaling can be through knowledge transfer, policy incidence and commercialization. Scaling can also be technology-driven and institution-driven processes. In the experience of the CSVs in Southeast Asia, a combination of various approaches was implemented to achieve scaling of CSA via CSVs. The CSVs have leveraged knowledge transfer activities via farmer-farmer to engagements and roving workshops. The CSVs also maximized the opportunities in national policies where it can mainstream CSA and CSVs. Policies such as Vietnam’s Nong Thon Moi national rural development program, Myanmar’s Climate-Smart Agriculture Strategy and the Philippine Department of Agriculture systemwide program called Adaptation and Mitigation Initiative in Agriculture, are all significant policy drivers of scaling CSA via CSVs in these countries. Albeit, on its early stages, the CSV in the Philippines and the work of IIRR in Cambodia have also utilized an economic, market-driven approach to scaling specific CSA options for these communities.

description: Discussing whether a machine is intelligent is relevant, but more urgent is the question whether our collaborations with machines are intelligent. An intelligent collaboration with Artificial Intelligence (AI) requires complementary traits, since there is no point in teamwork when all actors possess similar qualities. Consciousness, common sense, intuition, intentionality, imagination, morality, emotional intelligence and phenomenological experience are capacities that computers don’t have. Contrary to computers, humans can learn things that natural selection did not pre-program us with. Siri Beerends stresses in her article, that these human capacities are important to complement artificial intelligence and guide further developments in AI.

description: The COVID-19 pandemic has undoubtedly changed the standards and affected all aspects of our lives, especially social communication. It has forced people to extensively wear medical face masks, in order to prevent transmission. This face occlusion can strongly irritate emotional reading from the face and urges us to incorporate the whole body as an emotional cue. In this paper, we conduct insightful studies about the effect of face occlusion on emotion recognition performance, and showcase the superiority of full body input over the plain masked face. We utilize a deep learning model based on the Temporal Segment Network framework, and aspire to fully overcome the face mask consequences. Although facial and bodily features can be learned from a single input, this may lead to irrelevant information confusion. By processing those features separately and fusing their prediction scores, we are more effectively taking advantage of both modalities. This framework also naturally supports temporal modeling, by mingling information among neighboring frames. In combination, these techniques form an effective system capable of tackling emotion recognition difficulties, caused by safety protocols applied in crucial areas.

Aharonov-Bohm electrodynamics in material media: a scalar e.m. field cannot cause dissipation in a medium

description: In the extension of Maxwell equations based on the Aharonov-Bohm Lagrangian the e.m. field has an additional degree of freedom, namely a scalar field generated by charge and currents that are not locally conserved. We analyze the propagation of this scalar field through two different media (a pure dielectric and an ohmic conductor) in a range of frequencies such that the properties of the media are independent from the frequency. We find that an e.m. scalar wave cannot propagate in a material medium. If a scalar wave in vacuum impinges on a material medium it is reflected, at most exciting in the medium a pure "potential" wave (which we also call a "gauge" wave) propagating at $c$, the speed of light in vacuum, with a vector potential whose Fourier amplitude is related to that of the scalar potential by $ω\mathbf{A}_{0}=\mathbf{k}ϕ_{0}$, where $ω^{2}=c^{2}\left\vert \mathbf{k}\right\vert^{2}$.
