Analisis Sentimen dan Emosi Publik pada Awal Pandemi COVID-19 Berdasarkan Data Twitter dengan Pendekatan Berbasis Leksikon

Coronavirus Disease 2019 (COVID-19) merupakan penyakit menular yang disebabkan oleh Severe Acute Respiratory Illness Coronavirus. Penyebaran virus ini tergolong sangat cepat dan sulit dikendalikan sehingga pada Maret 2020, organisasi kesehatan dunia mendeklarasikan COVID-19 sebagai pandemi. Pandemi COVID-19 memberi dampak negatif hampir di segala aspek kehidupan. Mulai dari sosial, ekonomi, hingga psikologis publik. Selama pandemi, aktivitas di luar rumah terbatas. Korban PHK bertambah. Hal-hal tersebut diduga melatarbelakangi publik mengalami gangguan psikis. Oleh karenanya, perlu pemantauan keadaan psikologis agar kesehatan mental publik dapat tetap terjaga. Tujuan penelitian ini adalah mengkaji sentimen dan psikis publik yang dilihat melalui keadaan emosi publik selama pandemi COVID-19 periode Maret-Juli 2020. Data penelitian adalah data Twitter yang dianalisis menggunakan analisis sentimen dan emosi dengan pendekatan berbasis leksikon. Hasil penelitian menunjukan sentimen negatif lebih banyak diekspresikan dan ketakutan adalah emosi yang paling dirasakan publik. Hasil tersebut dapat dijadikan masukan khususnya bagi pemerintah agar lebih memerhatikan keadaan emosi publik.
Monge-Amp\`{e}re operators, energy functionals, and uniqueness of Sasaki-extremal metrics

We develop some pluripotential theoretic techniques for the transversally holomorphic foliation of a Sasakian manifold. We prove the convexity of the K-energy along weak geodesics for Sasakian manifolds. This implies that the K-energy is bounded below if a constant scalar curvature structure exists with those metrics minimizing it. More generally, a relative version of the K-energy is convex, and bounded below if there exists a Sasaki-extremal metric, providing an important necessary condition for Sasaki-extremal metrics. Another application is a proof of the uniqueness of Sasaki-extremal metrics, for a fixed transversally holomorphic structure on the Reeb foliation.
RECORDS OF PHARMACEUTICAL AND BIOMEDICAL SCIENCES Hepatocellular carcinoma pathogenesis: Epigenetics and relationship with cancer hallmarks

On the global scale, primary liver cancer (PLC) is the second leading cause of death due to cancer in men, and the third most prevalent cause of death in both sexes. Hepatocellular carcinoma (HCC) accounts for almost 75% of the total cases among primary liver malignancies. Curative operations for HCC include liver resection, ablation, and transplantation. However, a timely diagnosis is required for these operations to be successful. Hepatocarcinogenesis is a multistep process and can be induced by molecular alterations at both the genetic and epigenetic levels. The characteristic pathogenesis mechanisms of HCC are abnormal signal transduction resulting in uncontrolled cell proliferation, loss of apoptosis or programmed cell death, tissue invasion and metastasis allowing the spread of cancer, and finally angiogenesis which leads to the enhanced blood supply of tumors. In addition to epigenetic control of tumorigenesis. The p53 cell-cycle pathway, mutations in oxidative stress pathways, PI3K/AKT/mTOR, and Ras/Raf/MAPK signaling pathways are of great important pathways in HCC pathogenesis. Crosstalk between these pathways may be targeted by anti-cancer medications.
Orthogonal polynomials, Laguerre Fock space and quasi-classical asymptotics

Continuing our earlier investigation of the Hermite case [J. Math. Phys. 55 (2014), 042102], we study an unorthodox variant of the Berezin-Toeplitz quantization scheme associated with Laguerre polynomials. In particular, we describe a "Laguerre analogue" of the classical Fock (Segal-Bargmann) space and the relevant semi-classical asymptotics of its Toeplitz operators; the former actually turns out to coincide with the Hilbert space appearing in the construction of the well-known Barut-Girardello coherent states. Further extension to the case of Legendre polynomials is likewise discussed.
The Tight Constant in the Dvoretzky-Kiefer-Wolfowitz Inequality

Let F^ n denote the empirical distribution function for a sample of n i.i. d. random variables with distribution function F. In 1956 Dvoretzky, Kiefer and Wolfowitz proved that P(√n sup x (F^ n (x)−F(x))>λ)≤C exp(−2λ 2 ), where C is some unspecified constant. We show that C can be taken as 1, provided that exp(−2λ 2 )≤1/2. In particular, the two-sided inequality P(√n sup x |F^ n (x)−F(x)|>λ)≤2 exp(−2λ 2 ) holds without any restriction on λ. In the one-sided as well as in the two-sided case, the constants cannot be further improved
NEW EVALUATION OF THE K-ε TURBULENCE MODEL FORFREE BUOYANT PLUMES

Several versions of the k- l turbulence model are examined as to their suitability for Computational fluid dynamics (CFD) modeling of free turbulent jets and buoyant plumes. The study is based largely on the availability of relatively new experimental data for turbulent buoyant plumes. The modeling includes the effect of buoyancy on the production of turbulence and examines several different models for this source term, including the standard gradient diffusion model, the generalized gradient diffusion model, and an algebraic model. The fluctuations in mixture fraction are also briefly examined.
Velocity and heat transfer measurements in thermal convection

Measurements were taken of the heat transport and vertical component of the fluid velocity in a horizontal layer of water heated from below. The heat transfer results were well correlated by a simple power law relationship and indicated the possibility of flow transitions even at relatively high Rayleigh numbers. The velocity measurements were obtained optically and compared to predictions of Kraichnan.
Coherent control of two-photon transitions in a two-level system with broadband absorption

Multiphoton transition probability can be manipulated by tailoring the ultrashort laser pulses. In this paper, we theoretically and experimentally investigate the influence of the absorption bandwidth and line shape on the coherent control of two-photon transitions in two-level system by manipulating the femtosecond laser pulse with the spectral phase step. A coherent feature with a coherent peak and two coherent dips can be achieved if the absorption bandwidth is less than twice of the laser spectral bandwidth. The absorption bandwidth decides the coherent peak or dip intensity, and the absorption line shape affects the symmetry of the two coherent dips.
Same graph, different data: A usability study of a student-facing dashboard based on self-regulated learning theory

Student-facing learning analytics dashboards have the potential to reconnect students with their purpose for learning, reminding them of their goals and promoting reflection about their learning journey. However, far less is known about the specifics of the relationship between different types of visualisations and data presented in dashboards and their impact on students’ motivation. In this study, we used a Human-Centred Design method across three iterations to (1) understand how students prioritise similar visualisations when presenting different data (2) examine how they interact with these, and (3) propose a dashboard design that would accommodate students’ different motivational needs. In the first iteration, 26 participants ranked their preferred visualisations using paper prototypes; in the second iteration, a digital wireframe was created based on the results from the first iteration to conduct user tests with two participants; and in the third iteration, a high-fidelity prototype was created to reflect findings from the previous iterations. Overall, findings showed that students mostly valued setting goals and monitoring their progress from a multiple goals approach, and were reluctant about comparing their performance with peers due to concerns related to promoting unproductive competition amongst peers and data privacy. Implications for educators and learning designers are discussed.
A study of impact of childhood maltreatment on depressive disorder in adults

Childhood maltreatment (CM), also known as early life stress or childhood trauma, is a major risk factor for the onset of mental illnesses, including Major Depressive Disorder. The purpose of the research was to determine how common CM was among people who had been diagnosed with a depressive condition and to analyse the cumulative impact of several forms of CM that often occurred together. The study compared 150 patients diagnosed with major depressive disorder to 150 age- and sex-matched healthy controls. The purpose of the SCIDI was to confirm a diagnosis of depression and rule out other possible mental health problems. Depressive symptoms were also evaluated using the Beck Depression Inventory. Prevalence of childhood abuse was measured using the Childhood Trauma Questionnaire (CTQ). The findings showed that more than 80% of those diagnosed with depression also had CM. The strongest link was found between emotional maltreatment and both an earlier start and greater severity of major depressive disorder. More impairment is shown when many CMT kinds are present at once. Ultimately, this study adds to our knowledge of CM and its severe link to depression. There is a strong correlation between childhood maltreatment and adult depression, with more than 88% of depressed people seeking treatment for their condition reporting some kind of abuse.
COMBINED CAUDAL EPIDURAL WITH GENERAL ANESTHESIA FOR LUMBAR DISCECTOMY

: Background: Lumbar Discectomy can be effectively performed using various anesthetic techniques. General anesthesia is more frequently used for these surgeries, though regional anesthesia when combined with general anesthesia is proven to be safe in few studies. Aim of the Work: To compare the intra operative and short term post-operative outcome variable in patients undergoing primary single level lumbar discectomy under combined caudal epidural with general anesthesia versus general anesthesia alone. Patients and Methods: This study included 100 patients aging 25 – 40 years old, admitted to operating room in Ain Shams University hospitals for single-level lumbar discectomy. The patients were divided into two groups of 50 each: Group A received general anesthesia, Group B, in addition to GA, received caudal epidural using 20 ml Bupivacaine 0.25% injected in the caudal region. Results: Intra operative HR, MAP, narcotic consumption, blood loss were lower in the Caudal Epidural with GA group. Postoperative 1 st analgesia needed was less in the GA group. Postoperative VAS score and PONV were higher in the GA group when compared to combined caudal epidural with GA. There was no motor affection in both groups and sensory affection was with a median at T10 in the group receiving Caudal epidural with GA. Conclusion: Epidural caudal anesthesia can safely be combined with GA for single leveled lumbar discectomy. It reduces intraoperative tachycardia and hypertension, blood loss, intraoperative and postoperative IV analgesic requirements and PONV.
Transient solution for a plane‐strain fracture driven by a shear‐thinning, power‐law fluid

This paper analyses the problem of a fluid‐driven fracture propagating in an impermeable, linear elastic rock with finite toughness. The fracture is driven by injection of an incompressible viscous fluid with power‐law rheology. The relation between the fracture opening and the internal fluid pressure and the fracture propagation in mobile equilibrium are described by equations of linear elastic fracture mechanics (LEFM), and the flow of fluid inside the fracture is governed by the lubrication theory. It is shown that for shear‐thinning fracturing fluids, the fracture propagation regime evolves in time from the toughness‐ to the viscosity‐dominated regime. In the former, dissipation in the viscous fluid flow is negligible compared to the dissipation in extending the fracture in the rock, and in the later, the opposite holds. Corresponding self‐similar asymptotic solutions are given by the zero‐viscosity and zero‐toughness (J. Numer. Anal. Meth. Geomech. 2002; 26:579–604) solutions, respectively. A transient solution in terms of the crack length, the fracture opening, and the net fluid pressure, which describes the fracture evolution from the early‐time (toughness‐dominated) to the large‐time (viscosity‐dominated) asymptote is presented and some of the implications for the practical range of parameters are discussed.

Evaluation of Bioceramic Putty in Pulpotomy of Immature Permanent Molars With Symptoms of Irreversible Pulpitis

Purpose This study aimed to evaluate the effectiveness of both mineral trioxide aggregate (MTA) and bioceramic putty (Well-Root PT) in the pulpotomy of immature permanent molars diagnosed with symptoms of irreversible pulpitis. Materials and methods The study included 30 immature permanent molars with symptoms of irreversible pulpitis in 30 healthy children aged six to eight years. They were randomly distributed into the following two groups according to the material used: group 1 included 15 first permanent molars capped by MTA and group 2 included 15 first permanent molars capped by bioceramic putty. Clinical and radiographical evaluations of the treatment results were made after one week, three months, six months, nine months, and 12 months. Results The success rate in the bioceramic putty group was 93.3% clinically and radiographically after a 12 months follow-up, whereas in the group that underwent MTA treatment no cases of failure were registered with a 100% success rate. No statistical differences were observed between groups (p=0.309). The dentin bridge was formed in 60% of the MTA group and 33.3% of the bioceramic group without any statistically significant differences (p=0.272) after a 12 months follow-up. Conclusion Pulpotomy using biocompatible materials (MTA and bioceramic putty) on immature permanent molars with symptoms of irreversible pulpitis is considered acceptable and effective.
Iterative methods for an inverse heat conduction problem

Abstract - We consider the problem of reconstruction of the temperature from measurements of the temperature and heat flux on a part of the boundary and present iterative methods for solving this problem. The characteristic feature of the methods is the fact that in each iteration step, well-posed problems for the same equation are solved. The regularizing character of the methods comes from suitable choice of boundary conditions. This fact allows one to use standard numerical packages. Some numerical experiments are given.
The Mesoscale Kinetic Energy Spectrum of a Baroclinic Life Cycle

Abstract The atmospheric mesoscale kinetic energy spectrum is investigated through numerical simulations of an idealized baroclinic wave life cycle, from linear instability to mature nonlinear evolution and with high horizontal and vertical resolution (Δx ≈ 10 km and Δz ≈ 60 m). The spontaneous excitation of inertia–gravity waves yields a shallowing of the mesoscale spectrum with respect to the large scales, in qualitative agreement with observations. However, this shallowing is restricted to the lower stratosphere and does not occur in the upper troposphere. At both levels, the mesoscale divergent kinetic energy spectrum—a proxy for the inertia–gravity wave energy spectrum—resembles a −5/3 power law in the mature stage. Divergent kinetic energy dominates the lower stratospheric mesoscale spectrum, accounting for its shallowing. Rotational kinetic energy, by contrast, dominates the upper tropospheric spectrum and no shallowing of the full spectrum is observed. By analyzing the tendency equation for the ki.
Spectroscopy of luminous infrared galaxies at 2 microns: 1. The ultraluminous galaxies (L(sub IR) approximately greater than 10 (exp 12) solar luminosity)

We present high-quality spectra covering the K window at a resolving power of 340 for a sample of 13 ultraluminous (L(sub IR) approximately greater than 10(exp 12) solar luminosity) infrared-selected galaxies, and line fluxes for a comparison sample of 24 lower luminosity galaxies. The 2 micrometers spectra of 10 of the ultraluminous galaxies are characterized by emission and absorption features commonly associated with stars and star formation; two others have the red power-law spectra and Br gamma line widths of Seyfert 1 galaxies; the final galaxy has strong emission from hot dust. We have found no broad-line active nuclei not already known from optical observations, despite the fact that the extinction at 2 micrometers is 1/10 that at optical wavelengths; any putative Seyfert 1 nuclei must be deeply buried. Powerful continua and emission lines from H2 and Br gamma are detected in all the ultraluminous galaxies. Comparing the H2 1-0 S(1), Br gamma, and 2 micrometers and far-infrared luminosities to those of the lower luminosity galaxies yields several major results. First, the dereddened Br gamma emission, relative to the far-infrared luminosity is significantly depressed in the ultraluminous sample, when compared to the lower luminosity galaxies. Five of the ultraluminous galaxies have L(sub Br gamma)L(sub IR) ratios lower than for any of the comparison objects. Second, the H2 1-0 S(1) luminosity is also responsible, directly or indirectly, for producing the excited H2, and that the H2 apparently comes from optically thin regions in both classes of objects. Third, eight of the 13 ultraluminous systems have lower 2 micrometers/far-infrared luminosity ratios than any of the lower luminosity galaxies, and five of these are the galaxies also deficient in Br gamma. These three findings may be understood if the the H2, Br gamma, and 2 mircometers continua in the ultraluminous galaxies arise from spatially distinct regions, with the continuum and Br gamma largely coming from volumes optically thick even at 2 micrometers, and obscured in such a fashion that the extinctions measured using optical spectroscopy do not properly measure the true optical depths. If this is the case, then even near-infrared spectroscopy may be unable to exclude the presence of undetected powerful active galactive nuclei in the ultraluminous galaxies.

Control of pattern formation in a single feedback system by photonic bandgap structures

We present the observation of the manipulation of modulational instability in a nonlinear dissipative system by a periodic photonic lattice. We use a setup based on a photorefractive BaTiO3 crystal in a single feedback mirror configuration leading to the formation of hexagonal patterns. Additionally, we impose an optical lattice to induce one or two-dimensional photonic band-gap structures with variable parameters. We show that by varying the lattice periodicity, thus adjusting the transverse spatial frequencies associated to the bandgap, we can induce patterns of particular symmetry or suppress the modulational instability when the position of the lattice bandgap coincides with the instability gain.
Convex projective surfaces with compatible Weyl connection are hyperbolic

We show that a properly convex projective structure $\mathfrak{p}$ on a closed oriented surface of negative Euler characteristic arises from a Weyl connection if and only if $\mathfrak{p}$ is hyperbolic. We phrase the problem as a non-linear PDE for a Beltrami differential by using that $\mathfrak{p}$ admits a compatible Weyl connection if and only if a certain holomorphic curve exists. Turning this non-linear PDE into a transport equation, we obtain our result by applying methods from geometric inverse problems. In particular, we use an extension of a remarkable $L^2$-energy identity known as Pestov's identity to prove a vanishing theorem for the relevant transport equation.
Estimasi Angka Partisipasi Kasar Perguruan Tinggi Level Kabupaten/Kota di Pulau Kalimantan Tahun 2020 dengan Small Area Estimation Hierarchical Bayes Beta-Logistic

Peningkatan kualitas pendidikan bukan hanya menjadi agenda nasional, tetapi juga menjadi prioritas dari agenda internasional. Berdasarkan Susenas Maret 2020, diketahui bahwa perguruan tinggi (PT) memiliki Angka Partisipasi Kasar (APK) terendah dibandingkan jenjang pendidikan lainnya. Pulau Kalimantan merupakan pulau dengan APK PT terendah pada tahun 2020. Kebutuhan data pada area kecil sangat diperlukan agar kebijakan peningkatan kualitas pendidikan tinggi tepat sasaran. Walaupun Susenas Maret 2020 dirancang untuk menyajikan estimasi hingga level kabupaten atau kota, tetapi nilai Relative Standard Error (RSE) beberapa kabupaten/kota yang lebih dari 25% menunjukan bahwa penduga langsung memiliki presisi yang kurang memadai. Oleh karena itu, penelitian ini mengaplikasikan estimasi tidak langsung menggunakan Small Area Estimation (SAE) dengan metode Empirical Best Linear Unbiased Predictor (EBLUP) dan Hierarchical Bayes Beta-logistic (HB Beta-logistic) untuk memperbaiki presisi penduga langsung. Hasil penelitian menunjukkan bahwa penduga HB Beta-logistic merupakan penduga yang paling presisi dibandingkan penduga langsung dan penduga EBLUP.

Roots of random polynomials whose coefficients have logarithmic tails

It has been shown by Ibragimov and Zaporozhets [In Prokhorov and Contemporary Probability Theory (2013) Springer] that the complex roots of a random polynomial Gn(z)=∑nk=0ξkzk with i.i. d. coefficients ξ0,…,ξn concentrate a.s. near the unit circle as n→∞ if and only if Elog+|ξ0|<∞. We study the transition from concentration to deconcentration of roots by considering coefficients with tails behaving like L(log|t|)(log|t|)−α as t→∞, where α≥0, and L is a slowly varying function. Under this assumption, the structure of complex and real roots of Gn is described in terms of the least concave majorant of the Poisson point process on [0,1]×(0,∞) with intensity αv−(α+1)dudv.
The rigidity of Ricci shrinkers of dimension four

In dimension $4$, we show that a nontrivial flat cone cannot be approximated by smooth Ricci shrinkers with bounded scalar curvature and Harnack inequality, under the pointed-Gromov-Hausdorff topology. As applications, we obtain uniform positive lower bounds of scalar curvature and potential functions on Ricci shrinkers satisfying some natural geometric properties.
