Studi Efektifitas Metode ABaBta Dalam Pembelajaran Literasi Siswa Kelas Rendah MI Lombok Timur
Authors: Hulaimi Ahmad
Published: April 2022

Pembelajaran adalah aktivitas di kelas yang dilakukan oleh guru dengan peserta didik sehingga menimbulkan interaksi baik antara guru, peserta didik, sumber belajar dan lingkungan yang ada, sehingga peserta didik tidak hanya menjadi obyek tapi aktor, begitu juga denga guru tidak hanya satu-satunya sumber belajar, tapi lebih kepada penunjuk, pengarah dan pendidik. Pembelajaran tersebut akan efektif apabila disertai dengan penguasaan metode pembelajaran yang baik bagi guru. Ada pepatah pendidikan yang sering kita dengar, yakni : Materi pembelajaran adalah sesuatu yang penting, tetapi metode pembelajaran jauh lebih penting dari pada materi pembelajaran; Metode pembelajaran adalah sesuatu yang penting, tetapi guru jauh lebih penting dari pada metode pembelajaran; Guru adalah sesuatu yang penting, tetapi jiwa guru jauh lebih penting dari seorang guru itu sendiri. Pernyataan tersebut menunjukkan urgensinya metode dalam pembelajaran, begitu juga dengan gurunya karena core learning ada pada guru itu sendiri, tapi jika guru kurang menguasai metode pembelajaran, maka bisa dipastikan pembelajaran tersebut akan monoton dan menyebabkan siswa akan bosan dalam belajar.

Metode ABaBta merupakan metode yang dipergunakan oleh guru dalam pembelajaran anak didik di tingkat dasar MI/SD. ABaBta singkatan dari (Amati, Dengar, Baca, dan Ceritakan) adalah akronim dari konsep pembelajaran yang ada dalam pendidikan pondok pesantren di Lombok Timur yakni Adabte (bahasa sasak : perilaku kita). Makna inilah yang menginspirasi terbentuknya metode ABaBta yang akan digunakan dalam pembelajaran literasi di Madrasah Ibtidaiyah yang ada di Kabupaten Lombok Timur.

Dalam beberapa studi pendahuluan ditemukan tingkat literasi dasar di Madrasah Ibtidaiyah di Kabupaten Lombok Timur masih tinggi yang mencakup literasi baca-tulis khususnya di kelas rendah yakni kelas 1 s/d 3, hal ini menjadi problem pendidikan karena baca-tulis saja sudah bermasalah apalagi pada tingkatan selanjutnya. Persoalan tersebut disebabkan banyak faktor salah satunya adalah pendekatan dan penggunaan metode dalam pembelajaran yang belum efektif diterapkna oleh guru. Dalam studi ini peneliti ingin menggali dan melihat bagaimana studi efektifitas metode ABaBta dalam pembelajaran literasi siswa kelas rendah MI Lombok Timur.

Published: April 2022

Five species of genus Asparagus are recognized in the flora of Algeria: A. acutifolius L., A. albus L., A. horridus L., A. officinalis L., and the endemic A. altissimus Munby. The chorology of each of these species is fairly well known. In this study, morphological variation and the anatomical features of the cladodes have been evaluated in respect to each taxonomic unit and ecogeographical distribution and suggest distinct adaptive strategies. Analysis have been performed on twenty-nine natural populations sampled along the east-west bioclimatic gradient of the Northern Algeria. Multivariate analysis based on the main diagnostic descriptors, underlines the interspecific differentiation particularly with respect to the stigma type bifid versus trifid, shape of flowers, color of berry, and the number of cladodes in a fascicle. For each species the anatomy of the cladodes is unique, unlike that of stems and roots. Interspecific differentiation was observed in the form of cross-sections of the cladode, thickness of the cuticle, shape of epidermal cells, number of vascular bundles and presence of raphides. Morphological and anatomical traits of the cladode
constitute important interspecific criteria within the genus Asparagus.

The participation of women in the environmental movements and their association with forest resources in some areas are notable throughout the world. A comparative study to understand the perception and participation of women in forest protection programmes in the fringe villages of Sundarban Biosphere Reserve is the main focus of this paper. Four villages from two blocks of Sundarban Biosphere Reserve are selected. The entire work is mainly based on primary data. For comparative analysis, Chi-square and Cramer's V values are used. The ordinal regression method is used for relationship analysis. Although there are many differences in socio-economic factors and involvement in forest protection committees, there are no disagreements in the perception of women regarding the significance of forest protection of Sundarban. In fine, the focus is given on the inclusion of women's ideas in the decision-making process for the advancement of Sundarban Biosphere Reserve.

Published: April 2022

Deep convolutional neural networks (CNNs) with strong learning abilities have been used in the field of image super-resolution. However, some CNNs depends on a single deep network to training an image super-resolution model, which will have poor performance in complex screens. To address this problem, we propose a hybrid denoising CNN (HDCNN). HDCNN is composed of a dilated block (DB), RepVGG block (RVB) and feature refinement block (FB), a single convolution. DB combines a dilated convolution, batch normalization (BN), common convolutions, activation function of ReLU to obtain more context information. RVB uses parallel combination of convolution and BN, ReLU to extract complementary width features. FB is used to obtain more accurate information via refining obtained feature from the RVB. A single convolution collaborates a residual learning operation to construct a clean image. These key components make the HDCNN have good performance in image denoising. Experiment shows that the proposed HDCNN enjoys good denoising effect in public datasets.
EFFECTS OF SUNLIGHT AND SHADOW ON THE SURFACES OF PIGEON TOWERS IN CENTRAL ASIA: CASE STUDIES IN IRAN, QATAR, EGYPT AND SAUDI ARABIA
Authors: Momeni Kourosh , Shiri Tohid
Published: April 2022

In many parts of the world, especially Central Asia, pigeon towers have been constructed as traditional buildings with different forms and types to keep pigeons. These buildings are cylindrical, cubic, dome-like and multi-cylinder in shape. This study was conducted to identify the effects of sunlight and shadow on the surfaces of pigeon towers in Iran, Qatar, Egypt, and Saudi Arabia with hot and dry or humid climates. Several pigeon towers with different types and structures in these countries were selected and modeled in detail in Rhino 5. Radiance and Ecotect were then employed to measure solar radiation and shadow on the surfaces of the pigeon towers on the hottest day of the year. According to the graphical and numerical results obtained, sunlight and shadow differently affected the surfaces of the different pigeon towers. The effect level of sunlight and shadow on the single-form pigeon towers was higher than on the vaults. In fact, solar radiation was lower and shadow was higher per square meter of the surfaces of the vaults constructed as pigeon towers in close proximity. These houses were therefore found to be the optimal type for the hot and dry or humid climate in Central Asia.
PUSHing Core-collapse Supernovae to Explosions in Spherical Symmetry. V. Equation of State Dependency of Explosion Properties, Nucleosynthesis Yields, and Compact Remnants
Authors: Ghosh Somdutta , Wolfe Noah , Fröhlich Carla
Published: April 2022

In this fifth paper of the series, we use the parameterized, spherically symmetric explosion method PUSH to investigate the impact of eight different nuclear equations of state (EOS). We present and discuss the explosion properties and the detailed nucleosynthesis yields, and predict the remnant (neutron star or black hole) for all our simulations. For this, we perform two sets of simulations. First, a complete study of nonrotating stars from 11 to 40 M
⊙ at three different metallicities using the SFHo EOS; and, second, a suite of simulations for four progenitors (16 M
⊙ at three metallicities and 25 M
⊙ at solar metallicity) for eight different nuclear EOS. We compare our predicted explosion energies and yields to observed supernovae and to the metal-poor star HD 84937. We find EOS-dependent differences in the explosion properties and the nucleosynthesis yields. However, when comparing to observations, these differences are not large enough to rule out any EOS considered in this work.
Wakefield Acceleration in a Jet from a Neutrino-driven Accretion Flow around a Black Hole
Authors: Kato Yoshiaki , Ebisuzaki Toshikazu , Tajima Toshiki

We have investigated electromagnetic (EM) wave pulses in a jet from a neutrino-driven accretion flow (NDAF) around a black hole (BH). NDAFs are massive accretion disks whose accretion rates are

M

̇

≈

0.01–10 M
⊙ s−1 for stellar-mass BHs. Such an extreme accretion may produce a collimated relativistic outflow like a magnetically driven jet in active galactic nuclei and microquasars. When we consider strong toroidal magnetic field stranded in the inner region of an NDAF disk and magnetic impulses on the jet, we find that they lead to the emanation of high-energy emissions for gamma-ray bursts, as well as high-energy cosmic rays. When Alfvénic wave pulses are generated by episodic immense accretions, they propagate along the large-scale structured magnetic field in the jet. Once the Alfvénic wave pulses reach nearly the speed of light in the underdense condition, they turn into EM wave pulses, which produce plasma wakes behind them. These wakefields exert a collective accelerating force synchronous to the motion of particles. As a result, the wakefield acceleration premises various observational signatures, such as pulsating bursts of high-energy gamma rays from accelerated electrons, pulses of neutrinos from accelerated protons, and protons with maximum energies beyond 1020 eV.

Using Bayesian analyses we study the solar electron density with the NANOGrav 11 yr pulsar timing array (PTA) data set. Our model of the solar wind is incorporated into a global fit starting from pulse times of arrival. We introduce new tools developed for this global fit, including analytic expressions for solar electron column densities and open source models for the solar wind that port into existing PTA software. We perform an ab initio recovery of various solar wind model parameters. We then demonstrate the richness of information about the solar electron density, n

E
, that can be gleaned from PTA data, including higher order corrections to the simple 1/r
2 model associated with a free-streaming wind (which are informative probes of coronal acceleration physics), quarterly binned measurements of n

E
and a continuous time-varying model for n

E
spanning approximately one solar cycle period. Finally, we discuss the importance of our model for chromatic noise mitigation in gravitational-wave analyses of pulsar timing data and the potential of developing synergies between sophisticated PTA solar electron density models and those developed by the solar physics community.
Is There an Enormous Cold Front at the Virial Radius of the Perseus Cluster?
Authors: Walker S. A. , Mirakhor M. S. , ZuHone J. , Sanders J. S. , Fabian A. C. , Diwanji P.
Published: April 2022

We present new XMM-Newton observations extending the mosaic of the Perseus cluster out to the virial radius to the west. Previous studies with ROSAT have reported a large excess in surface brightness to the west, possibly the result of large-scale gas sloshing. In our new XMM-Newton observations we have found two X-ray surface brightness edges at 1.2 and 1.7 Mpc to the west. The temperature measurements obtained with Suzaku data indicate that the temperature increases sharply at each edge, consistent with what would be expected from cold fronts. However the the XMM-Newton data are affected by stray light, which at present is a poorly understood source of systematic error that can also lead to curved features in X-ray images. To test our results, we compared our X-ray surface brightness profile with that obtained from ROSAT PSPC data. While the edge at 1.2 Mpc is confirmed by ROSAT PSPC, the ROSAT data quality is insufficient to confirm the outer edge at 1.7 Mpc. Further observations with future X-ray telescopes will be needed to confirm the existence of the outer edge at 1.7 Mpc. By comparing with numerical simulations, we find that these large cold fronts require a large impact parameter, and low-mass ratio mergers that can produce fast gas motions without destroying the cluster core.
Quantifying Chemical and Kinematical Properties of Galactic Disks
Authors: Hu 胡 Guozhen 国真 , Shao 邵 Zhengyi 正义
Published: April 2022

We aim to quantify the chemical and kinematical properties of Galactic disks with a sample of 119,558 giant stars having abundances and 3D velocities taken or derived from the APOGEE DR17 and Gaia EDR3 catalogs. A Gaussian mixture model is employed to distinguish the high-α and low-α sequences along the metallicity by simultaneously using chemical and kinematical data. Four disk components are identified and quantified; they are named the hαmp, hαmr, lαmp, and lαmr disks and correspond to the high-α or low-α, and metal-poor or metal-rich properties. Combined with the spatial and stellar-age information, we confirm that they are well interpreted by the two-infall formation model. The first infall of turbulent gas quickly forms the hot and thick hαmp disk with consequent thinner hαmr and lαmr disks. Then the second gas accretion forms a thinner and outermost lαmp disk. We find that the inside-out and upside-down scenario does not only satisfy the overall Galactic disk formation of these two major episodes but is also presented in the formation sequence of the three inner disks. Importantly, we reveal the inverse age–[M/H] trend of the lαmr disk, which means its younger stars are more metal-poor, indicating that the rejuvenated gas from the second accretion gradually dominates later star formation. Meanwhile, the recently formed stars converge to [M/H] ∼ −0.1 dex, demonstrating a sufficient mixture of gas from two infalls.
Simple Analytic Formula Relating the Mass and Spin of Accreting Compact Objects to Their Rapid X-Ray Variability

Published: April 2022

Following the previous research on epicyclic oscillations of accretion disks around black holes (BHs) and neutron stars (NSs), a new model of high-frequency quasiperiodic oscillations (QPOs) has been proposed, so-called cusp torus (CT) model, which deals with oscillations of fluid in marginally overflowing accretion tori (i.e., tori terminated by cusps). According to preliminary investigations, the model provides better fits of the NS QPO data compared to the relativistic precession (RP) model. It also implies a significantly higher upper limit on the Galactic microquasar BH spins. A short analytic formula has been noticed to well reproduce the model’s predictions on the QPO frequencies in Schwarzschild spacetimes. Here we derive an extended version of this formula that applies to rotating compact objects. We start with the consideration of Kerr spacetimes and derive a formula that is not restricted to a particular specific angular momentum distribution of the inner accretion flow, such as a Keplerian or constant one. Finally, we consider Hartle–Thorne spacetimes and include corrections implied by the NS oblateness. For a particular choice of a single parameter, our relation provides frequencies predicted by the CT model. For another value, it provides frequencies predicted by the RP model. We conclude that the formula is well applicable to rotating oblate NSs and both models. We briefly illustrate the application of our simple formula on several NS sources and confirm the expectation that the CT model is compatible with realistic values of the NS mass and provides better fits of data than the RP model.
The Primary Proton Spectrum of the Hadronic PeVatron Candidate HAWC J1825-134
Authors: Dzhatdoev Timur , Podlesnyi Egor , Vaiman Igor
Published: April 2022

The γ-ray spectrum of the source HAWC J1825-134 measured with the High Altitude Water Cherenkov (HAWC) observatory extends beyond 200 TeV without any evidence for a steepening or cutoff. There are some indications that the γ-rays detected with HAWC were produced by cosmic-ray protons or nuclei colliding with the ambient gas. Assuming primary protons, we inquire which shape of the primary proton spectrum is compatible with the HAWC measurements. We find that the primary proton spectrum with the power-law shape of γ

p
= 2.2 and the cutoff energy E

c−p
> 500 TeV describes the data well. However, much harder spectra with γ

p
down to 1.3 and E

c−p
as low as 200 TeV also do not contradict the HAWC measurements. The former option might be realized if the accelerator is inside or very near to the γ-ray production zone. The latter option is viable for the case of a cosmic-ray source that effectively confines low-energy (E

p
< 10 TeV) accelerated protons. Using publicly available data of the Fermi-LAT space γ-ray telescope, we derive upper limits on the intensity of the HAWC J1825-134 source in the 1 GeV–1 TeV energy range. We show that the account of these upper limits drastically changes the interpretation: only hard (γ

p
< 1.7) spectra describe the combined HAWC and Fermi-LAT data sets well.

Published: April 2022

The subject of switchbacks, defined either as large angular deflections or polarity reversals of the magnetic field, has generated substantial interest in the space physics community since the launch of the Parker Solar Probe (PSP) in 2018. Previous studies have characterized switchbacks in several different ways and have been restricted to data available from the first few orbits. Here, we analyze the frequency of occurrence of switchbacks per unit distance for the first full eight orbits of PSP. In this work, events that reverse the sign of the magnetic field relative to a regional average are considered switchbacks. A significant finding is that the rate of occurrence falls off sharply approaching the Sun near 0.2 au (40 R
⊙) and rises gently from 0.2 au outward. The analysis is varied for different magnetic field cadences and for different local averages of the ambient field, confirming the robustness of the results. We discuss implications for the mechanisms of switchback generation. A publicly available database has been created with the identified reversals.
Limiting Flux versus Redshift as a Flag of New Physics
Authors: Loeb Abraham
Published: April 2022

I show that General Relativity sets an absolute upper limit on the energy flux observed from a cosmological source as a function of its redshift. Detecting a brighter source in gravitational waves, neutrinos or light, would flag new physics. The derived flux limit can also be used to determine the maximum redshift possible for any source with an unknown origin.

Les mutations économiques dont l’ouverture à la concurrence, conduisent les entreprises de pompes funèbres et la Poste à redéfinir les missions des salariés en relation de service. Pour les conseillers funéraires, on observe une professionnalisation croissante accompagnée par une augmentation des contraintes réglementaires. Il devient notamment un spécialiste de réseaux d’acteurs professionnels. Pour les guichetiers de la Poste, sont introduites de nouvelles contraintes commerciales qui modifient les relations avec la clientèle. Le guichetier devient polyvalent : il doit prendre en charge simultanément des fonctions administrative, financière et commerciale tout en conseillant le client. La qualité de service devient un objet de transaction entre l’agent et le client. Les objectifs de rentabilité et de qualité relationnelle avec la clientèle peuvent être contradictoires dans la réalisation de l’activité des agents. Ce contexte de travail invite à questionner les régulations individuelles et collectives mises en œuvre par les agents pour gérer ces contradictions.

Vers une définition de l’éducateur comme « expert »
Authors: Prouvez Valentine
Published: April 2022

À partir de l’examen des lignes directrices des référentiels métiers et des parcours de formation des travailleurs sociaux, tels qu’ils ont été récemment révisés par le législateur, nous proposons d’amorcer une réflexion critique sur le développement de la notion d’expertise et l’adossement des contenus de formation aux « savoirs » universitaires.
Enhanced existence time of solutions to evolution equations of Whitham type
Authors: Ehrnström Mats , Wang Yuexun
Published: April 2022

We show that Whitham type equations \begin{document}$u_t + u u_x -\mathcal{L} u_x = 0$\end{document}, where \begin{document}$L$\end{document} is a general Fourier multiplier operator of order \begin{document}$\alpha \in [-1, 1]$\end{document}, \begin{document}$\alpha\neq 0$\end{document}, allow for small solutions to be extended beyond their ordinary existence time. The result is valid for a range of quadratic dispersive equations with inhomogenous symbols in the dispersive regime given by the parameter \begin{document}$\alpha$\end{document}.
A Moser theorem for multiscale mappings
Authors: Zhao Xuefeng , Li Yong
Published: April 2022

In this paper, we study the persistence of invariant tori in nearly integrable multiscale twist mappings with intersection property and high degeneracy in the integrable part. Such results are also presented for the mappings with distinct number of angles and actions, which affirms the existence of lower-dimensional invariant tori in such mappings. Hence we establish a Moser's theorem in multiscales.
Unbiased parameter inference for a class of partially observed Lévy-process models
Authors: Ruzayqat Hamza , Jasra Ajay
Published: April 2022

We consider the problem of static Bayesian inference for partially observed Lévy-process models. We develop a methodology which allows one to infer static parameters and some states of the process, without a bias from the time-discretization of the afore-mentioned Lévy process. The unbiased method is exceptionally amenable to parallel implementation and can be computationally efficient relative to competing approaches. We implement the method on S & P 500 log-return daily data and compare it to some Markov chain Monte Carlo (MCMC) algorithm.
An efficient algorithm of fuzzy reinstatement labelling
Authors: Zhao Shuangyan , Wu Jiachao
Published: April 2022

The fuzzy reinstatement labelling ($ FRL $) puts forward a reasonable method to rewind the acceptable degrees of arguments in fuzzy argumentation frameworks. The fuzzy labelling algorithm ($ FLAlg $) computes the $ FRL $ by infinitely approximating the limits of an iteration sequence. However, the $ FLAlg $ is unable to provide an exact $ FRL $, and its computation complexity depends on not only the number of arguments but also the accuracy. This brings a quick increase in complexity when higher accuracy is acquired. In this paper, through the in-depth study of the $ FLAlg $, we introduce an effective algorithm for decomposing $ FRL $ by strongly connected components. For simple fuzzy frameworks in the form of trees, odd cycles, and even cycles, the new algorithm provides an exact value of the limit. Therefore, by avoiding the infinite approximation process, it is independent of accuracy. And for complex frames, the new algorithm outputs an approximate value to the $ FLAlg $. It is more efficient because the number of arguments in the approximation process is usually reduced.
Analysis of Covid 19 disease with SIR model and Taylor matrix method
Authors: UÇAR Deniz , ÇELİK Elçin
Published: April 2022

Covid 19 emerged in Wuhan, China in December 2019 has continued to spread by affecting the whole world. The pandemic has affected over 328 million people with more than 5 million deaths in over 200 countries which has severely disrupted the healthcare system and halted economies of the countries. The aim of this study is to discuss the numerical solution of the SIR model on the spread of Covid 19 by the Taylor matrix and collocation method for Turkey. Predicting COVID-19 through appropriate models can help us to understand the potential spread in the population so that appropriate action can be taken to prevent further transmission and prepare health systems for medical management of the disease. We deal with Susceptible–Infected–Recovered (SIR) model. One of the proposed model's improvements is to reflect the societal feedback on the disease and confinement features. We obtain the time dependent rate of transmission of the disease from susceptible $ \beta(t) $ and the rate of recovery from infectious to recovered $ \gamma $ using Turkey epidemic data. We apply the Taylor matrix and collocation method to the SIR model with $ \gamma $, $ \beta(t) $ and Covid 19 data of Turkey from the date of the first case March 11, 2020 through July 3, 2021. Using this method, we focus on the evolution of the Covid 19 in Turkey. We also show the estimates with the help of graphics and Maple.

Published: April 2022

Fixed point theory is one of the most interesting areas of research in mathematics. In this direction, we study some unique common fixed point results for a pair of self-mappings without continuity on fuzzy metric spaces under the generalized contraction conditions by using "the triangular property of fuzzy metric". Moreover, we present weak-contraction and generalized Ćirić-contraction theorems. The results are supported by suitable examples. Further, we establish a supportable application of the fuzzy differential equations to ensure the existence of a unique common solution to validate our main work.
Galerkin time discretization scheme for the transmission dynamics of HIV infection with non-linear supply rate
Authors: Attaullah  , Drissi Ramzi , Weera Wajaree
Published: April 2022

The present work implements the continuous Galerkin-Petrov method (cGP(2)-method) to compute an approximate solution of the model for HIV infection of $ \text{CD4}^{+} $ T-cells. We discuss and analyse the influence of different clinical parameters on the model. The work also depicts graphically that how the level of $ \text{CD4}^{+} $ T-cells varies with respect to the emerging parameters in the model. Simultaneously, the model is solved using the fourth-order Runge Kutta (RK4) method. Finally, the validity and reliability of the proposed scheme are verified by comparing the numerical and graphical results with those obtained through the RK4 method. A numerical comparison between the results of the cGP (2) method and the RK4 method reveals that the proposed technique is a promising tool for the approximate solution of non-linear systems of differential equations. The present study highlights the accuracy and efficiency of the proposed schemes as in comparison to the other traditional schemes, for example, the Laplace adomian decomposition method (LADM), variational iteration method (VIM), homotopy analysis method (HAM), homotopy perturbation method (HAPM), etc. In this study, two different versions of the HIV model are considered. In the first one, the supply of new $ \text{CD4}^{+} $ T-cells from the thymus is constant, while in the second, we consider the production of these cells as a monotonically decreasing function of viral load. The experiments show that the lateral model provides more reasonable predictions than the former model.
Forms of Fanon Remain
Authors: De Walt Patrick S.
Published: April 2022

This chapter applies Frantz Fanon's notion of third person consciousness to the educational experiences of an Africana male faculty member within a higher educational institution. Additional concepts were also integrated such as the 5E instructional model, nigrescence, and ethic and intellectual development models to analyze those experiences. Using personal narrative, an analysis of those experiences with students and colleagues was conducted in a layered approach: 1) identity, 2) philosophy, 3) pedagogy, 4) the interplay of all three, and lastly, 5) next steps.
A Nontraditional Student Returns to Teach Nontraditional Students
Authors: Krueger Erica
Published: April 2022

This chapter chronicles the story of the author's degree completion path as a nontraditional student and how that evolved into the author becoming an instructor for this same subsegment of the post-secondary student population. The return to teach happened following completion of a Master's degree. Returning to teach nontraditional students effectively and successfully has proven to be an undertaking the author finds rewarding as it provides ample opportunity for the needs of current and future nontraditional students to benefit from the combination of education and lived experiences of a nontraditional student returning to teach nontraditional students.
Resistencia
Authors: Sánchez-Connally Patricia , Cabello Constanza
Published: April 2022

This chapter focuses on the experiences of two Latina, first generation immigrant doctoras who developed and taught an inaugural Introduction to Critical Race Theory (CRT) course at a predominantly white institution in the Northeast. The authors discuss their salient identities that served as a catalyst to reimagine a teaching collaboration. Drawing from their cultural values, the authors comment on how they worked together during a contentious year to teach a course that affirmed the stories of people of color and immigrants. The authors share how the implementation, pedagogical perspectives, and goals for the course were informed by CRT in different ways, specifically relying on counterstorytelling as an approach to challenge dominant narratives and using the classroom as a counterspace for students of color. The chapter proposes two emerging dynamics the authors believe can assist in continuing to innovate teaching: first, reimagining diversity in the curriculum and second, forging faculty and staff teaching collaborations.
A Review on Artificial Intelligence for Electrocardiogram Signal Analysis
Authors: Chaitanya M Krishna , Sharma Lakhan Dev , Roy Amarjit , Rahul Jagdeep
Published: April 2022

Cardiovascular disease (CVD) is a broad term encompassing a group of heart and blood vessel abnormalities that is the leading cause of death worldwide. The most popular and low-cost diagnostic tool for assessing the heart electrical impulses is an electrocardiogram (ECG). Automation is required to reduce errors and human burden while interpreting ECG signals. In recent years, deep learning shows better performance in ECG classification and has also shown that automated classification of ECG signals can improve accuracy and efficiency. In this chapter, the authors review the research work on ECG signals using deep learning methods like deep belief network (DBNK), convolutional neural network (CNNK), long short-term memory (LSTMY), recurrent neural network (RNNK), and gated recurrent unit (GRUT). In the research articles published between 2017 and 2021, CNNK was found to be the most appropriate technique for feature extraction.
