Abstract
This research presents a novel ensemble fuzzy deep learning approach for brain Magnetic Resonance Imaging (MRI) analysis, aiming to improve the segmentation of brain tissues and abnormalities. The method integrates multiple components, including diverse deep learning architectures enhanced with volumetric fuzzy pooling, a model fusion strategy, and an attention mechanism to focus on the most relevant regions of the input data. The process begins by collecting medical data using sensors to acquire MRI images. These data are then used to train several deep learning models that are specifically designed to handle various aspects of brain MRI segmentation. To enhance the model’s performance, an efficient ensemble learning method is employed to combine the predictions of multiple models, ensuring that the final decision accounts for different strengths of each individual model. A key feature of the approach is the construction of a knowledge base that stores data from training images and associates it with the most suitable model for each specific sample. During the inference phase, this knowledge base is consulted to quickly identify and select the best model for processing new test images, based on the similarity between the test data and previously encountered samples. The proposed method is rigorously tested on real-world brain MRI segmentation benchmarks, demonstrating superior performance in comparison to existing techniques. Our proposed method achieves an Intersection over Union (IoU) of 95% on the complete Brain MRI Segmentation dataset, demonstrating a 10% improvement over baseline solutions.

ABSTRACTUsing the method of moments, we first analyse reference and present dual‐loop antennas with a perturbation segment and branched feedline, respectively. The loop elements of each antenna are gradually rotated for an increased 3 dB axial ratio bandwidth. Analysis reveals that as the loop rotation angle increases, the bandwidths of the reference and present antennas reach 20% and 43%, respectively, twice and three times as broad as those of the corresponding antennas without the rotation. Next, we modify the present antenna using a sequential rotation technique and discuss the radiation characteristics. The simulated results are verified with experimental ones.
An innovative hybrid load shifting and curtailing technique for operating a plug‐in hybrid electric vehicle integrated microgrid system in a clean and cost‐effective manner

Published: February 2025

AbstractDemand‐side management (DSM) tactics such as load shifting (LSP) and load curtailment (LCP) improve energy efficiency in a low‐voltage microgrid (MG). LCP encourages load reduction, whereas LSP directs elastic loads to low‐cost times. The MG under consideration includes price‐based (PBDR) and incentive‐based demand response (IBDR), as well as a hybrid DSM (HDSM) that blends LSP and IBDR. Plug‐in hybrid electric vehicles (PHEVs) are also incorporated to reduce expense and pollution. LSP shifts 20% of elastic loads, while IBDR cuts 35 kW to counter PHEV demand. Optimal generator scheduling seeks to reduce costs and emissions across five load profiles, including base load. The minimum generating cost is reduced from $252 (base load) to $234, $246, and $230 for LSP, IBDR, and HDSM, respectively. Emissions remain at 2916 kg for base and LSP‐based loads, while IBDR and HDSM reduce them to 2792 kg. Among all techniques, HDSM has the best trade‐off, with a $237 generation cost and 3116 kg emissions.

Abstract
Introduction Treatment options for patients with hemophilia (PWH) have changed substantially in the last years. This study aimed to compare hemophilia treatment in the eastern part of Germany in 2021 with data from 2015.
Methods Substitution diaries and patient records of PWH from 2021 were collected in 13 hemophilia centers from the “Kompetenznetz Hämorrhagische Diathese Ost” (KHDO) and compared with 2015.
Results A total of 130 children and 357 adults, 411 hemophilia A (HA) and 76 hemophilia B (HB), were included in 2021, and 359 were already analyzed in 2015. In 2021, 97.8% of children and 95.7% of adults with severe hemophilia had prophylaxis compared with 98.8 and 80.2% in 2015. Plasma-derived concentrates were used in 25.6%, recombinant in 30.2%, extended half-life (EHL) factor concentrates in 24.4%, and emicizumab in 19.8% of the children with severe HA (sHA). In adults with sHA, plasma-derived, recombinant concentrates, EHL, and emicizumab were used in 21.0, 33.2, 31.2, and 14.2%, respectively. All children and 93.3% of the adults with severe HB (sHB) were on EHL. Median annual factor consumption per body weight increased in adults with sHA, remained stable in children with sHA and adults with sHB, and decreased in children with sHB between 2015 and 2021. Annualized bleeding rate (ABR) decreased in children with sHB and sHA.
Conclusion The use of EHL and emicizumab has changed hemophilia treatment. About 50% of the sHA patients switched to EHL or emicizumab and almost all sHB patients to EHL. More adults with sHA received prophylaxis and ABR decreased in children.
Dose-Optimized Image Acquisition Parameters for Neonatal Chest Radiography: A Phantom Study Comparing Computed Radiography and Wireless Digital Radiography Needle Detectors

Published: February 2025

AbstractTo determine dose-optimized image acquisition parameters for good image quality (IQ) in neonatal chest radiography with a computed radiography (CR) CsBr needle detector vs. a wireless digital radiography (DR) CsI detector using different doses and filters.Physical resolution of the two detectors in unprocessed imaging of a contrast-detail phantom was automatically evaluated. Post-processed chest radiographic imaging of a neonatal phantom was used for Visual Grading Analysis (VGA) by three radiology raters. Different kVp, mAs, and filter settings were used. The VGA score (VGAS) and dose area product (DAP) were used to determine image acquisition parameters and dose levels for good image quality. Pixel data from segments corresponding to visual grading characteristics (VGC) was used to calculate signal-to-noise ratio, contrast-to-noise ratio (CNR), and signal profile curves. These results were compared to the raters’ “ground truth” by Spearman’s correlation.The CR detector had the highest resolution in unprocessed imaging, although this was dependent on a tube voltage of 66 kVp (P < 0.001), and more so than the DR detector. The VGAS showed no significant difference between the CR needle and the DR CsI detectors at the same DAP, or when using standard pediatric filtering of 3.5 mm Al + 0.1 mm Cu (P > 0.05). A lung dose level of 0.017 mSv was needed for good IQ (effective dose (E): 0.010 mSv). This was achievable with different acquisition parameters. Out of 24 segments, only the CNR of bone-to-soft-tissue had a good Spearman’s correlation (ρ > 0.50) to raters’ VGAS (P < 0.0001), mostly due to problems with image registration.The CR needle and DR CsI detectors have comparable IQ in neonatal chest radiography. In this study, an E of approximately 0.010 mSv was needed for good IQ.

Published: February 2025

AbstractTo compare postoperative edema, ecchymosis, and pain after rhinoplasty using conventional (classical) osteotomy versus powered (electric) micro-saw osteotomy techniques. Between December 2021 and May 2023, 90 patients aged 18 to 45 underwent rhinoplasty at our clinic. Of these, 45 patients underwent lateral and transverse osteotomy with powered saw instruments, whereas 45 underwent conventional osteotomy. A resident examined edema, ecchymosis, and pain on the first, third, and seventh postoperative days. The specialist was blinded to the osteotomy method (single-blind). Edema and ecchymosis were categorized using the Yücel modification of the Kara and Gokalan classification, and the pain was evaluated using the visual analog scale. The patients who underwent osteotomy with an electric micro-saw (group 1) had less edema on the first and third days than with conventional osteotomy (group 2). However, on the seventh day, although group 1 had slightly less edema than group 2, there were no significant differences. On the other hand, group 2 had significantly more ecchymosis on the first and third postoperative days compared with group 1, but there were no significant differences on the seventh day. On the first postoperative days, patients in group 2 reported significantly more pain on average compared with group 1. There were no significant differences in pain levels between the two groups on the third and seventh days following the surgery. After rhinoplasty, patients commonly suffer from edema, ecchymosis, and pain. Our research suggests that using a powered micro-saw effectively reduces early-stage ecchymosis and pain compared with the conventional low-to-low osteotomy technique. However, there were no notable differences between the two methods regarding edema, ecchymosis, and pain on the seventh day after surgery. The electric micro-saw appears to be a feasible alternative in the osteotomy step, showing effectiveness comparable to that of the conventional method.
Scaphoid Non-union Arthroscopic treatment without Bone Graft: Is it Possible?

Published: February 2025

AbstractScaphoid fractures are the most frequent fractures of carpal bones, accounting for 70 to 80% of all carpal fractures. Appropriate and early diagnosis of scaphoid fractures is imperative.To relieve symptoms and prevent degenerative changes, scaphoid non-union surgery should aim at healing and restoration of the normal anatomy, and correction of carpal deformities.Since the scaphoid non-unions are a heterogeneous group, and categorization is not easy, the management remains controversial with a reported failure rate as high as 40% and the absence of a “gold standard” treatment.Based on (a) Qu and Von Schroeder's new concepts on the osteogenic ability of the non-union cells stimulated by osteoinductive bone factors; (b) the encouraging results obtained by Illarramedi et al on decompression of the distal radius and ulna in Kiënbock disease treatment; and (c) along with the minimal surgical trauma of percutaneous and arthroscopic techniques, the authors have begun treating scaphoid non-unions without bone graft by using arthroscopic-assisted reduction and internal fixation with metaphyseal core decompression of the distal radius. The technique has also been used in advanced cases with “humpback” deformity and long-standing non-unions. Resting on the observations of CT scans and arthroscopic findings, we have introduced a new comprehensive classification of scaphoid non-union for better categorization and typification and provide an improved treatment approach. We recommend arthroscopic-assisted treatment in young and middle-aged non-smoking patients with scaphoid non-unions. Percutaneous fixation alone is sufficient for stable stages I and II, whereas additional core decompression of the distal radius can be used for unstable stages, for bone defects greater than 10 mm, and for the proximal pole non-unions. This method is not suggested in non-unions with significant sclerosis, with a complete absence of punctate bleeding of the proximal pole, and in those with a very small proximal fragment.
Queer Muslim solidarity: Working against binaries
Authors: Minty Sodah 
Published: February 2025

Abstract
This paper addresses unique intersectional identities within the Muslim community, and some common assumptions regarding “religious identity” and the blind spots that this creates in the therapeutic space. It discusses the author’s advocacy work for queer Muslims seeking an identity or cultural match with a Muslim therapist who also affirms their queer identities, and explores issues related to invisible and visible identities, intersectionality, belonging, and advocacy. This paper uses intersectionality as a framework to emphasize the added labor, adversity and invisible negotiations that Muslims who do not fit the stereotype “Muslim” face from all angles. Applying Jasbir Puar’s conceptualization of “homonationalism,” which captures the multiple negotiations queer Muslims living in the west face as they also navigate their other intersecting identities, this paper argues that the invisibility of some identities creates both barriers to mental health care and the potential for secret solidarity between provider and client. The reader is brought on a journey of secret solidarity—the bond formed between those who understand the risk of allying with queerness as a Muslim person, and the lengths we all go to be perceived a certain way while trying to make revolutionary change.
Spectrum of high-frequency gravitational waves from graviton bremsstrahlung by
the decay of inflaton: case with polynomial potential
Authors: Jiang Yiheng , Suyama Teruaki 
Published: February 2025

Abstract
We study the generation of high-frequency gravitational waves (GWs) through graviton
bremsstrahlung during the decay of inflaton in the post-inflationary universe, focusing on
scenarios with a polynomial inflaton potential. Two main reheating channels are considered:
decays into bosons (spin 0) and fermions (spin 1/2). We compute the resulting GW spectra
from three-body decays, where the inflaton decays into a pair of daughter particles and a
graviton. We numerically compute the GW spectra for various polynomial exponents by employing two
distinct approaches: one treating the inflaton as a collection of rest particles and the other
treating it as a coherently oscillating classical field. In the former approach, only gravitons
with energies below half the inflaton mass are produced, while the latter allows for the
production of gravitons with arbitrarily high energies when the potential exponent is 4 or
greater. This difference arises because the inflaton's oscillations are no longer described by a
single harmonic mode but instead consist of infinitely many harmonic modes with different
frequencies. As a result, the GW spectrum exhibits multiple peaks, with these peaks being less
pronounced for higher powers of the potential. We also examine the dependence of the GW spectrum
on the coupling constant between the inflaton and daughter particles. Our findings suggest that
future GW detectors targeting GWs in the GHz band, such as resonant cavities, may have the
capability to detect these signals, offering potential insights into the reheating phase of the
early universe.

Abstract
Measuring the growth of structure is a powerful probe for studying the dark sector,
especially in light of the σ
8 tension between primary CMB anisotropy and low-redshift
surveys. This paper provides a new measurement of the amplitude of the matter power spectrum,
σ
8, using galaxy-galaxy and galaxy-CMB lensing power spectra of Dark Energy Spectroscopic
Instrument Legacy Imaging Surveys Emission-Line Galaxies and the Planck 2018 CMB lensing
map. We create an ELG catalog composed of 24 million galaxies and with a purity of 85%,
covering a redshift range 0 < z < 3, with z
mean = 1.09. We implement several novel
systematic corrections, such as jointly modeling the contribution of imaging systematics and
photometric redshift uncertainties to the covariance matrix. We also study the impacts of various
dust maps on cosmological parameter inference. We measure the cross-power spectra over f
sky = 0.25 with a signal-to-background ratio of up to 30σ. We find that the choice of
dust maps to account for imaging systematics in estimating the ELG overdensity field has a
significant impact on the final estimated values of σ
8 and ΩM, with
far-infrared emission-based dust maps preferring σ
8 to be as low as 0.702 ± 0.030, and
stellar-reddening-based dust maps preferring as high as 0.719 ± 0.030. The highest preferred
value is at ∼ 3 σ tension with the Planck primary anisotropy results. These
findings indicate a need for tomographic analyses at high redshifts and joint modeling of systematics.

Abstract
Artificial intelligence is fast-growing and applied in a wide range of industries nowadays, including the healthcare sector. Dermatology is one of the areas where AI has a big influence, particularly when it comes to dermoscopy-based skin lesion diagnosis. This paper aims to develop useful techniques for disease image classification that make use of deep learning and machine learning techniques. Continuously, looking at and making suggestions for improvements is to raise the model’s efficacy during the training phases. The convolutional Neural Network (CNN) model was developed, trained, and evaluated on the Skin Cancer MNIST: HAM10000 data set, and subsequently deployed on Kaggel software using Python and the Keras framework. The results are mostly 0.95 or higher, models with Precision and Recall measurements are relatively stable. In particular, for cases like actinic keratosis, benign skin tumors, and vascular lesions, the values of Precision and Recall both reached level 1, indicating that there were no instances of incorrect predictions.

Published: February 2025

Abstract
Predicting the risk of developing various diseases using machine learning models, deep learning, and neural networks trained on electronic health record (EHR) data has become crucial in today’s healthcare landscape. However, safeguarding personal information remains a significant concern due to the potential for sensitive information leakage from EHR databases, which often contain personal information that, if revealed, can lead to identity theft, discrimination, and other types of harm. This study aims to apply synthetic data as a replacement for real databases to protect personal information while ensuring the responsible use of data for research, AI applications, and collaborative analysis. The research was conducted on two different EHR databases using a statistical model (Gaussian Copula Synthesizer) and a deep learning model (Conditional Generative Adversarial Network Synthesizer). Specifically, the study focused on forecasting diabetes risks in the next year and predicting Intensive Care Unit outcomes in EHRs. The quality of these synthetic datasets was evaluated using statistical metrics and machine learning efficiency. Moreover, data security efficiency was assessed using statistical-based privacy metrics, including k-Anonymity, l-Diversity, and ε–Identifiability values. The results demonstrate the significant quality and privacy of synthetic data generated by both models, highlighting the potential of the proposed pipeline of synthetic data-generating models in future healthcare applications.

Published: February 2025

Abstract
Surcharge load with prefabricated vertical drain (PVD) is a special soft soil improvement technique. The utilization of this technique leads the soft soil to reach the ultimate consolidation settlement effectively since it can save the time and cost for embankment construction. The effectiveness of using surcharge load with PVD to enhance the ultimate consolidation settlement of the soft soil is strongly dependent on the soil properties, surcharge load, the configuration of PVD such as spacing and penetration length. The current study investigates the effect of PVD spacing and penetration length on the consolidation settlement of the improved soft soil via finite element analysis program, Plaxis 2D 2017. The results showed that the soft soil with PVD different spacings as 1.0 m, 1.5 m and 2.0 m produced similar results for the ultimate consolidation settlement and the excess pore water pressure. In addition, this study also figured that PVD penetration lengths seemed to not affect remarkably the consolidation process of the improved soft soil when the PVD penetration length was 50%, 75% and 100%. It is noted that the results of the current study were based on a finite element analysis program. In the future, further laboratory and field tests should be carried out to better understand the consolidation settlement of the soft soil that subjected to surcharge load and improved by PVD as the vertical drains.
