Abstract

Hyperspectral cameras face challenging spatial-spectral resolution trade-offs and are more affected by shot noise than RGB photos taken over the same total exposure time. Here, we present a colorization algorithm to reconstruct hyperspectral images from a grayscale guide image and spatially sparse spectral clues. We demonstrate that our algorithm generalizes to varying spectral dimensions for hyperspectral images, and show that colorizing in a low-rank space reduces compute time and the impact of shot noise. To enhance robustness, we incorporate guided sampling, edge-aware filtering, and dimensionality estimation techniques. Our method surpasses previous algorithms in various performance metrics, including SSIM, PSNR, GFC, and EMD, which we analyze as metrics for characterizing hyperspectral image quality. Collectively, these findings provide a promising avenue for overcoming the time-space-wavelength resolution trade-off by reconstructing a dense hyperspectral image from samples obtained by whisk or push broom scanners, as well as hybrid spatial-spectral computational imaging systems., Comment: 16 Pages, 13 Figures, 3 Tables, for more information: https://mehmetkeremaydin.github.io/hypercolorization/

Abstract

We have constructed a new, fast, robust and reliable pipeline to detect variable stars from the ROTSE-IIId archival data. Turkish share of ROTSE-III archive contains approximately one million objects from a large field of view (1.85\dgr) and it considerably covers a large portion of northern sky ($\delta>-25\dgr$). The unfiltered ROTSE-III magnitude of the objects ranges from 7.7 to 16.9. The main stages of the new pipeline are as follows: Source extraction, astrometry of the objects, light curve generation and inhomogeneous ensemble photometry. A high performance computing (HPC) algorithm has also been implemented into the pipeline where we had a good performance even on a personal computer. Running the algorithms of the pipeline on a cluster decreases analysis time significantly from weeks to hours. The pipeline is especially tested against long period variable stars with periods of a few hundred days (e.g Mira and SR) and variables having periods starting from a few days to a few hundred days were detected., Comment: 8 pages, 5 figures 2 tables; last revision before published

Abstract

The aim of this study was to develop a measurement tool that can be used to determine the online teaching competency levels of teachers and instructors. During the validation, the draft scale was applied to online teachers and instructors actively involved in distance education. After the implementation processes, the sample was divided into two groups randomly (n1 = 158; n2 = 144). The first sample was used for Exploratory Factor Analysis (EFA), and the second sample for Confirmatory Factor Analysis (CFA). The EFA highlighted 17 items and 3 factors found in the final scale. Factors were found as Technology, Pedagogy, Ethical and Institution dimensions. The reliability analysis for the whole scale was 0.90, the Cronbach alpha reliability coefficient of sub-dimensions were found to be 0.87, 0.88, 0.78, respectively. In addition, the composite reliability (CR) value of the whole scale was calculated as 0.953 and the CR values for the sub-factors were calculated as 0.877, 0.871 and 0.832, respectively. As a result of the CFA, it was concluded that the scale could be used to measure online teaching competencies of teachers and instructors., Aydın, M., & Aydın, M. (2023).

Abstract

Abstract Background Acute coronary syndrome (ACS) is frequently reported in patients with coronavirus disease 2019 (COVID-19). Cytokine storm induced by interleukin-6 (IL-6) has been suggested to potentially cause myocardial injury in COVID-19. We investigated the association between baseline level of IL-6 and development of ACS in COVID-19 patients. Methods Demographic and clinical data of hospitalized COVID-19 patients from 2020 to 2022 were reviewed. Extracted data including patient characteristics, laboratory biomarkers, and systemic inflammation indexes in patients with or without ACS were reviewed and analyzed. Logistic regression models were applied to analyze predictors of ACS development and receiver-operating characteristic (ROC) curves were used to assess discriminatory power of IL-6 and other risk factors for predicting ACS development. Results Among 1,753 COVID-19 patients, 37 cases experienced ACS and 159 patients without main COVID-19 complications were randomly selected as controls. ACS patients were older (p = 0.001) and suffered from more comorbidities including diabetes (43% vs. 18%, p = 0.001), hypertension (40.5% vs. 24.5%, p = 0.050), ischemic heart disease (49% vs. 9%, p = 0.001), and hyperlipidemia (19% vs. 5%, p = 0.010). Also, decreased level of consciousness (31.6% vs. 2.5%, p = 0.001), ICU admission (65% vs. 2%, p = 0.001), and mortality events (70% vs. 0.6%, p = 0.001) were more prevalent in the ACS group. Baseline levels of IL-6 (p = 0.001), D-dimer (p = 0.026), troponin (p = 0.001), blood urea nitrogen (p = 0.002), and creatinine (p = 0.008) were higher in ACS patients but erythrocyte sedimentation rate (p = 0.013), hemoglobin (p = 0.033), and red blood cells (p = 0.028) were lower compared with controls. Also, age (OR: 1.06, p = 0.019), IL-6 (OR: 1.44, p = 0.047), and cardiovascular disease (CVD) (OR: 3.66, p = 0.043) were associated with ACS development. The area under the curve (AUC) of IL-6 and combined predictors respectively was 0.661 (p = 0.002) and 0.829 (p = 0.001). Conclusions High IL-6 concentration at baseline is a strong predictor for ACS development in COVID-19 patients. Also, elderly and concurrent CVD are significantly associated with ACS development.
