BackgroundAlthough bone pathologies and lesions can be detected via CT images, patients may be exposed to radiation exposure. In contrast to CT, MRI does not subject the patient to radiation exposure; however, it is incapable of detecting cortical bone. CT-like images, on the other hand, can circumvent this limitation. GAN and U-net were utilized to generate CT-like images from 3D MR images for the purpose of comparing them to actual CT images. ObjectiveThis study aims to generate CT-like images from MRI images in three dimensions using fundamental deep learning methods. Materials and MethodsThe pelvic region real CT images and MR images of the same patients were obtained from the GOLD atlas public data set. A total of 6,236 images were utilized to train the model using the Python-based Spyder program. The model was then evaluated using 332 images to compare the quality of CT-like images to that of real CT images and to establish a comparison between the two models ResultsThe cGAN model generated CT-like images with smaller mean absolute error (MAE) and mean square error (MSE) values (0.0244 ± 0.0197 and 0.0032 ± 0.0040, respectively), and larger Pearson correlation coefficient (PCC) and peak signal-to-noise ratio (PSNR) values (27.1221 ± 3.9920 and 0.9283 ± 0.0389, respectively). ConclusionThis research illustrates the capability of GAN to produce CT-like images from MR data, which could potentially serve as a substitute for authentic CT images when assessing bone morphologies.

Magnetic Resonance Imaging (MRI) plays a major role in the diagnosis of several diseases. However, the acquisition of measurements in the k-space domain, which is the basis for image reconstruction, takes a long time compared to other imaging modalities and is comparatively costly. In this context, undersampled MRI reconstruction is an approach for decreasing the acquisition duration and the exam's final cost. With this objective, both Compressed Sensing (CS) and Deep Learning (DL) provide techniques for generating good quality MRI images from undersampled measurements. In this paper, we combine CS and DL methods in order to investigate the potential increase in image quality over each isolated approach. We use reconstructions from from highly undersampled MRI signals using two CS approaches, the L1 and total minimizations, as inputs to a U-Net. We also use, for comparison, the reconstructions from the same undersampled signals using L2 minimization, and also test them as inputs to a U-net. The goal is to evaluate whether the the U-Net can improve the results of the CS reconstructions after learning from degraded and original image pairs. Our experimental results suggest that the combination of L1 or TV minimization with U-Nets can improve reconstruction, in terms of objective image quality, over each technique used in isolation.

As it is known the passive components like the resistor, the coil and the capacitor in reality are not ideal components and have a nonlinear component. In this paper is started from the real equivalent circuit of a capacitor and is created a nonlinear SPICE model whose static capacity varies with voltage. The correctness of the SPICE model is studied on the capacitive region of the capacitor. Also, a study of the behavior of the SPICE model without considering the variation with temperature, aging, ESL and ESR will be presented. All to be considered in a future paper. The behavior of the SPICE model is compared with the behavior of the real capacitor and with the SPICE behavior of the capacitor proposed by the component manufacturer.

High-quality fluorescence imaging of biological systems is limited by processes like photobleaching and phototoxicity, and also in many cases, by limited access to the latest generations of microscopes. Moreover, low temporal resolution can lead to a motion blur effect in living systems. Our work presents a deep learning (DL) generative-adversarial approach to the problem of obtaining high-quality (HQ) images based on their low-quality (LQ) equivalents. We propose a generative-adversarial network (GAN) for contrast transfer between two different separate microscopy systems: a confocal microscope (producing HQ images) and a wide-field fluorescence microscope (producing LQ images). Our model proves that such transfer is possible, allowing us to receive HQ-generated images characterized by low mean squared error (MSE) values, high structural similarity index (SSIM), and high peak signal-to-noise ratio (PSNR) values. For our best model in the case of comparing HQ-generated images and HQ-ground truth images, the median values of the metrics are 6·10-4, 0.9413, and 31.87, for MSE, SSIM, and PSNR, respectively. In contrast, in the case of comparison between LQ and HQ ground truth median values of the metrics are equal to 0.0071, 0.8304, and 21.48 for MSE, SSIM, and PSNR respectively. Therefore, we observe a significant increase ranging from 14% to 49% for SSIM and PSNR respectively. These results, together with other single-system cross-modality studies, provide proof of concept for further implementation of a cross-system biological image quality enhancement. © 2024, CC BY-SA.

Metacells are disjoint and homogeneous groups of single-cell profiles, representing discrete and highly granular cell states. Existing metacell algorithms tend to use only one modality to infer metacells, even though single-cell multi-omics datasets profile multiple molecular modalities within the same cell. Here, we present Cross-MOdal Embedding for MetaCell Identification (COEM), which utilizes an embedded space leveraging the information of both scATAC-seq and scRNA-seq to perform aggregation, balancing the trade-off between fine resolution and sufficient sequencing coverage. COEM outperforms the state-of-the-art method SEACells by efficiently identifying accurate and well-separated metacells across datasets with continuous and discrete cell types. Furthermore, COEM significantly improves peak-to-gene association analyses, and facilitates complex gene regulatory inference tasks. © 2022, CC BY.

The amount of waste in Indonesia is estimated to reach 68 million tons in 2019, of which 9.52 million tons is a plastic waste. With this amount, Indonesia is ranked second in the world as the largest producer of plastic waste. One area that suffers from plastic waste is the coastal area. This plastic waste is difficult to decompose and cause environmental problems. Likewise, it happened on the Tambaan coast in Tambaan sub-district, Panggungrejo subdistrict, Pasuruan city. Currently, accumulation of plastic waste is evident throughout the coastal area. The accumulation of scattered plastic waste and its proximity to the residents' settlements has become a hotbed of mosquitoes and caused a pungent smell. The Serving Doctoral program at Universitas Brawijaya offers a solution to process plastic waste into fuel oil such as diesel, kerosene, and premium. The technology used was Muryani's distillation from Wlingi, Blitar Regency. The technology can change certain types of plastic waste to produce fuel. Karang Taruna Bina Hang Tuah was acted as a reliable partner to assist the implementation of the technology on site. This study aims to strengthen the capacity of Karangtaruna in Tambaan Village to be more concerned about the environmental problems of Tambaan beach by processing waste that has been polluted by plastic waste. The results of plastic waste treatment showed that 10 kg of dried plastic waste can be transformed into diesel, premium and kerosene with the efficiency value of 60%, 35%, and 15%, respectively. © Published under licence by IOP Publishing Ltd.

This paper compares single microstrip antenna designs and microstrip arrays used for Manpack Radar with X-band frequency. Antenna array configurations were investigated for 1x2, 1x4, and 1x32 elements. A gain increase is required for each additional patch element. Patch dimensions are set at 9.17 x 10.10 x 0.035 mm. The parameters needed are X-Band frequency with gain >15 dBi, beamwidth angle of ≤5°, and bandwidth of more than 60 MHz. The simulation results show a good match with the target required for the 9.3 GHz frequency. The largest gain value numerically is obtained on the antenna with 32 patches, which is 17.1 dBi.
