Authors: Chen First Zidong , Hassan Second Fadratul Hafinaz 
Published: July 2023

Abstract

This article presents a medical image segmentation model based on a semi-STDP (Spike-Timing-Dependent Plasticity) optimization strategy. The study utilizes a modified Swin-Transformer as the feature extraction module and combines it with a pyramid model. The STDP is employed to optimize the semi-segmentation results generated by the pyramid model, achieving precise segmentation of medical images. The architecture and features of the modified Swin-Transformer are described in detail, highlighting its excellent performance in feature extraction. Next, the design concept of the pyramid model is introduced, which can extract and fuse features at different scales to enhance the accuracy and robustness of the segmentation results. Furthermore, an innovative neural network module called the STDP-based segmentation module is proposed. The proposed model is experimentally validated using two medical image datasets and compared with other classical medical image segmentation methods. The experimental results demonstrate significant improvements in accuracy and robustness, validating the effectiveness of the semi-STDP optimization strategy and the superiority of the proposed model. Finally, in-depth analysis and discussion of the experimental results are provided, along with prospects for future improvements. This research has important theoretical and practical implications for improving the accuracy and automation level of medical image segmentation.

Published: July 2023

Using the renormalized wavefunction approach, we examined the excitonic quantum beat in a three-level system in disk-shaped quantum dots. The non-stationary electron wave function and the time-dependent exciton absorption intensity under the effect of an intensity pump laser that resonates with two excited electron states were also provided. Our numerical findings demonstrate that the time-dependent exciton absorption intensity takes the shape of a periodic oscillation when the quantum dot is subjected to a powerful resonant pump laser. This is clear evidence that quantum beats appears in the quantum disk. Additionally, the dot radius and the pump field detuning significantly affect the beat characteristics, such as frequency and amplitude.

La acuicultura se enfrenta a grandes pérdidas económicas en cultivos de camarón blanco (Litopenaeus vannamei) debido a las enfermedades microbianas y virales. Una de estas enfermedades es la Necrosis Hepatopancreática Aguda (AHPND), la cual emergió en China en el año 2009, reportándose en México hasta el año 2013. Los agentes causales de AHPND en el camarón blanco son Vibrio parahaemolyticus y Vibrio harveyi, los cuales provocaron el 80% de las pérdidas en cultivos en los estados de Sonora, Sinaloa y Nayarit, México. Por este motivo, los objetivos de este estudio se enfocaron en identificar bacterias marinas como probióticos, capaces de inhibir a los agentes causales de AHPND. Las bacterias se aislaron de almejas, cangrejos, algas y agua marina de ecosistemas de Sonora y Baja California. Se analizó su capacidad hemolítica, degradación de celulosa y amilasa de las cepas seleccionadas, y su capacidad de inhibir a los patógenos. La identificación de las cepas probióticas se realizó con ensayos bioquímicas usando el sistema API y se confirmó mediante la amplificación del gen 16S rRNA. Se obtuvo que 10 aislados presentaron capacidad antagónica contra V. harveyi y se identificaron como: H3 Aeromonas hydrophila, mientras que los aislados J1, G10, H3 M, H2, G2, G2.1, 14 2.1, G3.2 y E 2.1 como Bacillus pumilus. En el caso de V. parahaemolyticus fueron: G2.1, H2, J1, G3.2 y E2.1. Para los ensayos de actividad hemolítica los aislados J1, G10 y E2.1 (B. pumilus) presentaron β hemolisis. Los aislados identificados como B. pumilus y A. hydrophila demostraron tener actividad antagónica contra V. paraheamolyticus y V. harveyi por lo que pueden ser catalogados como probióticos potenciales en base a los resultados obtenidos, los cuales contribuyen a conocer nuevas cepas benéficas para el biocontrol de estos patógenos y su aplicación permitirá evitar el uso de antibióticos en la acuicultura, reduciendo la incidencia de resistencia estos fármacos.

Craniospinal is known as the method to kill the cancer within a wide radiation area, starting from the cranial to spinal nervous system. In the case, the cancer has spread through the fluid of cerebro spinalis, such as medulloblastoma. We carried out the research to determine the isodose curve in medulloblastoma craniospinal patients and DVH (Dose Volume Histogram) statistic in the OAR (Organ at Risk) by using 3D-CRT radiotherapy technique. To conduct the radiative treatment, we used the moving Junction method in which the radiation was divided into three Iso section, i.e.: Section Iso brain with gantry 90° and 270°, Section Iso thoracic with gantry 0°, and Section Iso lumbar with gantry 0°. Then, we analyzed the isodose curves and DVH statistics created by photon beams of 6 MV and 10 MV with and without considering the dose absorbed by OAR. We found that the isodose curves created with considering the OAR dose were better than those created without considering the OAR dose. We also found that the dose absorbed by OAR was within the tolerance limit stated in ICRU guidelines.

Published: July 2023

Introduction: Following the COVID-19 outbreak in China in December 2019, viral spread started to be seen in many countries. In March 2020, simultaneous with the pandemic declaration, the first case was observed in Northern Cyprus. During this time, the emergency department visit patterns showed differences worldwide.
Aim: Thus, this study aims to compare and contrast the differences between pre-pandemic and pandemic period emergency department visits resulting from any kind of drug and/or substance intoxication. To do so, a retrospective analysis was held using two private university hospitals’ electronic recording systems for the periods of 1st December 2017-9th March 2020 (before the pandemic) and 10th March 2020-30th June 2022 (during the COVID-19 pandemic).
Results: The demographic data were collected, and the study-specific data were grouped into 5 different intoxication categories. Data collected were compared in terms of pre- and post-pandemic timescales. The results showed that there is no significant difference between the demographic data of patients however, intoxication-related emergency department visits were significantly lower during the pandemic compared to the pre-pandemic period.
Conclusion: This study will be a pioneer in contributing to many social problems, especially substance abuse, which was previously lacking in scientific data in Northern Cyprus.
Analisis Karakteristik FABA Sebagai Material Layering Timbunan Sampah
Authors: Fahriani Ferra , Hambali Roby 
Published: July 2023

Timbunan sampah yang berada pada Tempat Pemrosesan Akhir (TPA) seharusnya dilakukan layering (penutupan) dengan tanah secara rutin sesuai dengan ketentuan pengelolaan TPA. Penyedian material (tanah) sebagai material penutup timbunan sampah memerlukan biaya yang tidak sedikit, sehingga kegiatan penutupan timbunan sampah di TPA sering mengalami kendala. Pada kajian ini dilakukan suatu penelitian terhadap material pengganti tanah sebagai lapisan penutup timbunan sampah berupa Fly ash dan Bottm Ash (FABA). Sebagian material tanah yang biasa digunakan sebagai material layering timbunan sampah digantikan dengan FABA yang dicampur dengan kapur, kapur berfungsi untuk mengikat material tanah timbunan dan FABA. Komposisi campuran yaitu FABA 75% + 5% kapur + 20% tanah timbunan, FABA 75% + 10% kapur + 15% tanah timbunan serta FABA 90% +5% kapur + 5% tanah timbunan. Tujuan penelitian untuk mengetahui apakah FABA dapat digunakan sebagai material substitusi lapisan penutup (layering) dalam pengembangan teknologi layering timbunan sampah. Material campuran diuji karakteristik kekuatannya dilaboratorium berupa uji permeabilitas, berat isi tanah, kuat geser, analisa saringan, Atterberg Limit, dan CBR serta pemadatan. Parameter kekuatan material ini selanjutnya digunakan dalam pemodelan layering (timbunan sampah) dengan bantuan software geoteknik. Hasil Penelitian menunjukkan bahwa campuran material FABA tidak memenuhi syarat sebagai material layering sampah dikarenakan nilai permeabilitas yang tidak memenuhi syarat dalam sistem sanitary Landfill, walaupun memiliki nilai daya dukung yang baik berdasarkan nilai kohesi dan sudut geser tanah serta nilai stabilitas Landfill.

ObjectiveTo examine the validity of the 5-component SARC-F questionnaire for screening sarcopenia among patients with chronic kidney disease (CKD).MethodsEligible participants were enrolled from the Department of Nephrology, Ruijin Hospital, Shanghai Jiao Tong University School of Medicine from March 2019 to November 2019. Evaluations were performed using the self-administered SARC-F questionnaire. Sarcopenia was diagnosed by grip strength, the chair stand test and appendicular skeletal muscle mass. The severity of sarcopenia was evaluated by gait speed. We calculated the sensitivity and specificity of the SARC-F to evaluate construct validity. Moreover, receiver operating characteristic (ROC) curve analysis was performed to identify the cutoff value for nondialysis-dependent (NDD) CKD patients’ and maintenance hemodialysis (MHD) patients’ scores.ResultsA total of 105 NDD-CKD patients and 125 MHD patients were included, and the prevalence of sarcopenia was 5.7 and 31.2%, respectively. Among them, there were 21 (16.8%) MHD patients with severe sarcopenia but no NDD-CKD patients with severe sarcopenia. The sensitivity and specificity of the SARC-F were 16.7 and 98.0% for NDD-CKD patients, and 48.7 and 89.5% for MHD patients, respectively. For NDD-CKD patients, the area under the receiver operating characteristic curve (AUROC) of the total SARC-F score was 0.978 (95% confidence interval (CI): 0.929–0.997, p &lt; 0.001), and the cutoff value of 1 reached the highest Youden index of 0.950 and max ROC curve area of 0.974. For MHD patients, the AUROC of the total SARC-F score was 0.730 (95% CI: 0.644–0.806, p &lt; 0.001), and the cutoff value of 4 reached the highest Youden index of 0.383 and max ROC curve area of 0.691.ConclusionCKD patients, especially MHD patients, were at high risk of suffering sarcopenia. The SARC-F had low-to-moderate sensitivity but high specificity for screening sarcopenia among patients with CKD. The best cutoff values of the SARC-F score were different for screening sarcopenia among NDD-CKD and MHD patients.
