A Spaceborne Integrated S/Ka Dual-Band Dual-Reflector Antenna

by Zenan Yang, Weiqiang Han, Liang Tang, Haihua Wang, Yilin Wang and Yongchang Jiao

Micromachines 2026, 17(1), 124; https://doi.org/10.3390/mi17010124 (registering DOI) - 18 Jan 2026

Abstract

To address the diverse requirements of satellite communication applications involving medium-/low-rate reliable links and high-rate high-capacity services, an integrated S/Ka dual-band dual-reflector antenna is proposed as an effective solution. Owing to the stringent spatial constraints of satellite platforms, the longer operating wavelengths in the S-band lead to oversized feed horns in the integrated antenna design, which induces severe secondary aperture blockage, thus degrading aperture efficiency and impeding practical mechanical layout implementation. To alleviate this critical drawback, the proposed antenna achieves multi-band aperture reuse by deploying an array with four miniaturized S-band radiating elements around a broadband Ka-band feed horn. A frequency-selective surface (FSS)-based sub-reflector is further designed to effectively enhance the effective aperture size for the S-band operation, while ensuring unobstructed electromagnetic propagation in the Ka-band, thus enabling simultaneous dual-band high-gain radiation. After comprehensive electromagnetic simulation and parametric optimization for the antenna feed and the FSS sub-reflector, experimental measurements verify that the S-band left-hand and right-hand circularly polarized (LHCP/RHCP) channels achieve more than 20.2 dBic gains with more than 6° half-power beamwidths (HPBWs), and the Ka-band channel yields gains exceeding 41.2 dBic, with HPBWs greater than 0.8°.

Organoids 2026, 5(1), 4; https://doi.org/10.3390/organoids5010004 (registering DOI) - 18 Jan 2026

Abstract

Hepatoblastoma (HB) is a paediatric liver malignancy arising from hepatic precursor cells, with >90% of cases harbouring a mutation in exon 3 of CTNNB1. We present a fully genetically characterised HB tumour organoid (tumoroid) biobank, which allows for in vitro studies of disease progression and clonal dynamics in vitro. We established a biobank of 14 tumoroid lines from 9 different patients. Tumours and tumoroids were characterised by whole genome sequencing (WGS) and histology, revealing strong concordance in cell morphology and β-catenin staining. In tumour—tumoroid pairs, identical pathogenic CTNNB1 variants were found, alongside shared copy number alterations (CNAs) and mutations. Variant allele frequency (VAF) was consistently higher in tumoroids, indicating increased tumour purity in vitro. In addition to CTNNB1, we frequently observed ARID1A alterations (single-nucleotide variants [SNVs] or CNAs in 56% of patients), and MYC gains as described previously. In paired pre- and post-treatment samples, we observed a clear increase in mutational load, attributed to a chemotherapy signature. Notably, from one patient, we analysed 4 tumour samples (3 post-treatment) with 4 matching tumoroid lines, all carrying a novel BCL6 mutation and loss of ARID1A. Mutational profiles varied across samples from different locations, suggesting intratumoral heterogeneity and clonal selection during tumoroid derivation. Taken together, this biobank allows detailed analysis of HB tumour biology, including treatment-induced progression and clonal dynamics across temporally and spatially distinct samples. Full article

Performance Optimization of Series-Connected Supercapacitor Microbial Fuel Cells Fed with Molasses-Seawater Anolytes

by Jung-Chieh Su, Kai-Chung Huang, Chia-Kai Lin, Ai Tsao, Jhih-Ming Lin and Jung-Jeng Su

Electronics 2026, 15(2), 424; https://doi.org/10.3390/electronics15020424 (registering DOI) - 18 Jan 2026

Abstract

Microbial fuel cells (MFCs) utilizing livestock wastewater represent a critical path toward sustainable energy and net-zero emissions. To maximize this potential, this study investigates a novel circuit configuration, integrating twin MFCs with dual supercapacitors in a closed-loop system, to enhance charge storage and electricity generation. By utilizing molasses-seawater anolytes, the study establishes a performance benchmark for optimizing energy recovery in future livestock wastewater treatment applications. The self-adjusting potential difference between interconnected MFCs is verified, and supercapacitors significantly improve energy harvesting by reducing load impedance and balancing capacitor plate charges. Voltage gain across supercapacitors exceeds that of single MFC charging, demonstrating the benefits of series integration. Experimental results reveal that catholyte properties—electrical conductivity, salinity, pH, and dissolved oxygen—strongly influence MFC performance. Optimal conditions for a neutralized anolyte (pH 7.12) include dissolved oxygen levels of 5.37–5.68 mg/L and conductivity of 24.3 mS/cm. Under these conditions, supercapacitors charged with sterile diluted seawater catholyte store up to 40% more energy than individual MFCs, attributed to increased output current. While the charge balance mechanism of supercapacitors contributes to storage efficiency, its impact is less pronounced than that of conductivity and oxygen solubility. The interplay between electrochemical activation and charge balancing enhances overall electricity harvesting. These findings provide valuable insights into optimizing MFC-supercapacitor systems for renewable energy applications, particularly in livestock wastewater treatment. Full article

Association of Corneal Biomechanical Properties with Fingertip-Measured Advanced Glycation End Products and Carotenoids in Glaucoma Patients

by Keigo Takagi, Hinako Ohtani, Chisako Ida, Mizuki Koike, Kana Murakami and Masaki Tanito

J. Clin. Med. 2026, 15(2), 783; https://doi.org/10.3390/jcm15020783 (registering DOI) - 18 Jan 2026

Abstract

Background/Objectives: Advanced glycation end products (AGEs) and carotenoids are systemic indicators of metabolic and oxidative status, yet their influence on ocular tissue biomechanics remains unclear. This study investigated the relationships between systemic AGEs and skin carotenoid levels, as well as corneal biomechanical properties in glaucoma patients. Methods: A retrospective observational analysis was performed on 676 patients (1278 eyes) who attended the glaucoma clinic at Shimane University Hospital between May 2019 and August 2024. Fingertip skin autofluorescence (sAF)-based AGE scores using AGE Sensor^® and skin carotenoid scores using the Veggie Meter^® were collected as part of systemic evaluation. Corneal hysteresis (CH), corneal resistance factor (CRF), Goldmann-correlated intraocular pressure (IOPg), and corneal compensated intraocular pressure (IOPcc) were measured using the ocular response analyzer (ORA). Associations between systemic variables, AGEs, carotenoids, and ORA parameters were analyzed using univariate tests, mixed-effects regression models, and quartile-based comparisons. Results: The mean AGEs and carotenoid scores were 0.42 ± 0.10 arbitrary units and 338.5 ± 130.8 optical density units, respectively. Via a univariate analysis, an inverse association was found between carotenoid level and CRF; however, via multivariate analyses, neither AGEs nor carotenoid levels were associated with IOPg, IOPcc, CH, or CRF in any analysis. In contrast, demographic parameters showed significant associations with ORA parameters. Via quartile-based comparisons, a significant inverse correlation was found between AGEs and carotenoids (p < 0.0001). Conclusions: In conclusion, sAF-measured AGEs and skin carotenoids showed no remarkable associations with corneal biomechanical properties. AGEs and carotenoids demonstrated an inverse relationship with each other, and each marker was associated with several demographic parameters. Full article

Microbial Landscape of Pharmaceutical Failures: A 21-Year Review of FDA Enforcement Reports

by Luis Jimenez

BioTech 2026, 15(1), 8; https://doi.org/10.3390/biotech15010008 (registering DOI) - 18 Jan 2026

Abstract

By analyzing Food and Drug Administration (FDA) enforcement reports from 2004 to 2025, we can determine the incidence of microbial contamination in non-sterile and sterile drugs in the United States of America and, at the same time, compare the trends and patterns over a period of 21 years to determine the distribution and frequency of microbial contaminants. The most common microorganisms detected from 2019 to 2025 were the mold Aspergillus penicilloides, with 17 citations for sterile products, followed by 16 citations for non-sterile products of Burkholderia cepacia complex (BCC) bacteria. Analysis from the last 21 years revealed the dominant microbial contaminants belong to the BCC, reaching a maximum level between 2012 and 2019. Some of the previous microbial contaminants, such as Salmonella and Clostridium, decline in the 2019–2025 period, with no notifications issued. S. aureus and Pseudomonas contamination persisted through the years but at very low levels. Gram-negative bacteria contaminated non-sterile drugs more frequently than Gram-positive. A worrisome trend continued with unacceptable levels of enforcement reports not providing any information on the identity of the microbial contaminant. New species of Bacillus and Acetobacter nitrogenifigens were responsible for a significant increase in non-sterile drug recalls. The main driver for sterile product recalls over a 21-year period is the lack of assurance of sterility (LAS) where major failures in process design, control, and operational execution were not conducive to the control of microbial proliferation and destruction. Enforcement data analysis identified the problematic trends and patterns regarding microbial contamination of drugs, providing important information to optimize process control and provide a framework for optimizing risk mitigation. Although the 21-year landscape demonstrated that some microbial contaminants have been successfully mitigated, others remain resilient. The emergence of new contaminants highlights the evolving nature of microbial risk. The consistent problem with LAS is not only a major regulatory violation but also a potential catalyst for the next major healthcare-associated outbreak. Full article

Speed and Distance Redistribution—Lower Limb Power Strategy in Single-Leg-Approach Jumps

by Wei-Hsun Tai, Hsien-Te Peng, Jian-Zhi Lin, Hai-Bin Yu and Po-Ang Li

Life 2026, 16(1), 160; https://doi.org/10.3390/life16010160 (registering DOI) - 18 Jan 2026

Abstract

This study systematically investigated the influence of approach kinematics on the subsequent kinetics and power production strategies during the approach to running jumps with a single leg (ARJSL). Twenty-five physically active male university students performed ARJSL trials under two prescribed approach speeds (fast and slow) and three approach distances (3, 6, and 9 m) in a 2 × 3 within-subjects design. Three-dimensional motion capture synchronized with force platform data was used to quantify jump height (JH), vertical touchdown velocity (TDv), reactive strength index (RSI), peak joint power (hip, knee, and ankle), and joint stiffness. Significant approach speed × distance interactions were observed for JH (p = 0.006), TDv (p < 0.001), RSI (p = 0.014), ankle stiffness (p = 0.006), and peak power generation at all lower-limb joints (all p < 0.034). The results demonstrate that changes in approach strategy systematically alter the distribution of mechanical power among the hip, knee, and ankle joints, thereby influencing the effectiveness of horizontal-to-vertical momentum conversion during take-off. Notably, RSI and ankle stiffness were particularly sensitive to combined manipulations of speed and distance, highlighting their value as neuromechanical indicators of stretch–shortening cycle intensity and joint loading demands. In conclusion, ARJSL performance depends on finely tuned, speed- and distance-specific biomechanical adaptations within the lower extremity. These findings provide a constrained, joint-level mechanical characterization of how approach speed and distance interact to influence power redistribution and stiffness behavior during ARJSL, without implying optimal or performance-maximizing strategies.

Obesity Hypoventilation Syndrome in Children and Adolescents

by Duilio Petrongari, Paola Di Filippo, Francesca Cacciatore, Armando Di Ludovico, Giuseppe Francesco Sferrazza Papa, Sabrina Di Pillo, Francesco Chiarelli and Marina Attanasi

Children 2026, 13(1), 140; https://doi.org/10.3390/children13010140 (registering DOI) - 18 Jan 2026

Abstract

Obesity hypoventilation syndrome (OHS) is a severe and underrecognized respiratory disorder characterized by the coexistence of obesity, daytime hypercapnia, and sleep-disordered breathing. Although well described in adults, pediatric OHS remains poorly defined despite the rising prevalence of childhood obesity. Its pathophysiology is multifactorial, involving obesity-related mechanical constraints, impaired ventilatory control, altered chemosensitivity, and frequent overlap with obstructive sleep apnea. Clinical manifestations in children are often subtle and nonspecific, including snoring, sleep fragmentation, daytime sleepiness, and neurocognitive impairment, frequently leading to delayed diagnosis and, in some cases, acute cardiopulmonary decompensation. Management of pediatric OHS is challenging and largely extrapolated from adult data. Positive airway pressure therapy remains the cornerstone of treatment, while weight reduction is essential but difficult to achieve in pediatric populations. Pharmacological approaches such as medroxyprogesterone or acetazolamide remain experimental, with limited pediatric evidence. This review synthesizes current knowledge on pediatric OHS, focusing on epidemiology, pathophysiology, clinical presentation, diagnostic challenges, and therapeutic strategies. Increased awareness and earlier recognition are essential to prevent progression to chronic respiratory failure and long-term cardiovascular complications. Full article

A Smartphone-Based Application for Crop Irrigation Estimation in Selected South and Southeast Asia Countries

by Daniel Simonet, Ajita Gupta and Taufiq Syed

Sustainability 2026, 18(2), 990; https://doi.org/10.3390/su18020990 (registering DOI) - 18 Jan 2026

Abstract

Efficient irrigation planning in data-scarce regions remains challenging due to limited access to localized meteorological data, reliance on complex computer-based models, and the technical knowledge required to deploy them at the field scale. Hence, the need for accessible, smartphone-based tools that simplify soil water balance calculations using public data to support practical decision-making in resource-limited contexts. This smartphone-based application estimates Net and Gross Irrigation Requirements using a Soil Water Balance (SWB) framework. The app combines region-specific empirical formulations for Effective Rainfall (Pe) calculation. The application utilizes user-supplied crop and irrigation parameters and meteorological data available in the public domain and operates at multiple temporal scales (daily, 10-day, weekly, and monthly), thereby supporting flexible irrigation schedules. The performance of app was evaluated through simulation-based benchmarking against FAO-CROPWAT 8.0 using harmonized inputs across five representatives agro-climatic region: Central India, Southern Vietnam, Northern Thailand, Western Bangladesh, and Central Sri Lanka. Quantitative comparison showed deviations within ±5% for Effective Rainfall, crop evapotranspiration, Net Irrigation, and Gross Irrigation, and low mean bias values (−2.8% to +3.3%) show the absence of systematic over- or under-estimation compared to CROPWAT model. The application also demonstrated responsiveness to climatic variability. Although the validation is limited to few representative locations and assumed minimal runoff conditions, the results suggest that the proposed method is technically consistent and feasible in practice. This study demonstrates smartphone-based application as a decision support for field-level irrigation planning and water resource management, particularly in data-limited agricultural contexts.

Symbolic Transfigurations of Jinhua in The Secret of the Golden Flower (Taiyi Jinhua Zongzhi太乙金華宗旨): From Inner Alchemy to Interreligious Synthesis

by Danke Zhang

Religions 2026, 17(1), 113; https://doi.org/10.3390/rel17010113 (registering DOI) - 18 Jan 2026

Abstract

The Secret of the Golden Flower (Taiyi Jinhua Zongzhi 太乙金華宗旨), a Qing dynasty spirit-writing (fuji扶乩) text, is widely known through the Wilhelm–Jung translation lineage, where jinhua 金華 is rendered as “Golden Flower” and read as mandala-like symbolism. Based on a close reading of the Daozang Jiyao 道藏輯要version, this article argues that in the Chinese text jinhua is not primarily a floral image but a technical and experiential term for luminosity in Daoist inner-alchemical cultivation. Hua 華 is resemanticized from botanical “flower/flourishing” into “radiance,” and the work explicitly defines the key term as “jinhua is light”. The text further organizes cultivation into a three-stage trajectory—“sudden emergence”, “circulation”, and “great condensation”, through which qi 氣 is refined into light and luminosity stabilizes as spirit (shen 神). Finally, the analysis situates this luminous grammar within the work’s explicit Three Teachings (sanjiao 三教) framing: Confucian “illuminating virtue” (mingde 明德) and Buddhist idioms of luminous mind-nature (xin-xing guangming 心性光明) and dharma-body language function as a shared vocabulary for describing non-grasping awareness and embodied realization. On this basis, jinhua is best understood not as a decorative metaphor or a purely psychological symbol but as a practice-oriented mechanism of ontological luminosity, clarifying both the inner-alchemical logic of The Secret and the stakes of its modern reception.

Horticulturae 2026, 12(1), 105; https://doi.org/10.3390/horticulturae12010105 (registering DOI) - 18 Jan 2026

Abstract

A two-factor experiment was conducted using the cultivar ‘Xin you No. 2’ (Citrullus lanatus) to identify an efficient and green production model for drip-irrigated watermelon under plastic mulch in Southern Xinjiang. A basal organic fertilizer was applied at 2250 kg·ha⁻¹. The experimental design comprised three irrigation levels, maintaining soil moisture at 60–70% (W1), 70–80% (W2), and 80–90% (W3) of field capacity, and three nitrogen application rates: 180 (N1), 240 (N2), and 300 (N3) kg·ha⁻¹. This study systematically investigated the effects of water–nitrogen coupling on watermelon yield, quality, water use efficiency, and nitrogen partial factor productivity. The W2N2 treatment achieved the highest yield of 64,617.59 kg·ha⁻¹. Vine length, stem diameter, and dry matter accumulation increased with increasing nitrogen application under the W1 and W2 irrigation levels, but exhibited an initial increase followed by a decrease under the W3 condition. Water restriction combined with increased nitrogen application significantly enhanced the central sugar content, with the W1N3 treatment increasing it by 15.69% compared to CK. Conversely, the W1N1 treatment was most conducive to vitamin C accumulation, showing a 49.88% increase over CK. The total water consumption across the different treatments ranged from 362.12 to 493.92 mm. Both water use efficiency and irrigation water use efficiency reached their maximum values under the W1N3 treatment, at 21.94 kg·m⁻³ and 35.05 kg·m⁻³, respectively. In contrast, the highest partial factor productivity of nitrogen (NPFP) was observed under W3N1, reaching 239.33 kg·kg⁻¹. A comprehensive multi-index evaluation using the Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS) method indicated that the W1N3 treatment achieved the highest relative closeness (0.669), identifying it as the optimal water–nitrogen combination.

Wrapped Unsupervised Hyperspectral Band Selection via Reconstruction Error from Wasserstein Generative Adversarial Network

by Haoyang Yu, Hongna Zheng, Tao Yao, Yuling Zhang and Deyin Zhang

Remote Sens. 2026, 18(2), 326; https://doi.org/10.3390/rs18020326 (registering DOI) - 18 Jan 2026

Abstract

Wrapped unsupervised band selection (WUBS) is a powerful means of reducing the dimensions of hyperspectral images (HSIs) and has drawn much focus recently. Nevertheless, numerous WUBS approaches struggle to strike a balance between computational complexity and performance and typically disregard high-level information between bands. This paper presents a new reconstruction error-based algorithm called distance density (DD) and Wasserstein generative adversarial network (WGAN)-driven WUBS (DW-WUBS), which is intended to overcome these problems. Minutely, DW-WUBS employs DD to weigh the spectral fluctuation in different band groups and thus determine the detailed expression of the importance of each group. At the same time, it uses a sequential search method on the important band group instead of the original HSIs, thereby reducing the computational complexity of band retrieval. Afterwards, DW-WUBS trains a WGAN and applies its critical network to test the representativeness of the searched bands by considering their contribution to HSI reconstruction. This automatically derives underlying and higher-level structure information of the spectrum. The superiority of DW-WUBS is certified by comprehensive experiments on three benchmark data sets. For instance, on the Pavia Center scene, the peaked mean accuracy (MA) using the twelve bands chosen via DW-WUBS with the CART classifier exceeds the baseline (i.e., all bands) by 0.91% in the classification task.

Assessing Stability and Correlations Among Cotton Seed Quality Traits Across Multiple Environments Using the Stability Index

by Vasileios Greveniotis, Elisavet Bouloumpasi, Adriana Skendi, Dimitrios Kantas and Constantinos G. Ipsilandis

Appl. Sci. 2026, 16(2), 984; https://doi.org/10.3390/app16020984 (registering DOI) - 18 Jan 2026

Abstract

The stability of seed quality traits is a key factor for developing reliable cotton cultivars with consistent performance across diverse environments. This study evaluated six seed traits (1000-seed weight, crude protein, oil, ash, crude fiber, and moisture) across five commercial upland cotton cultivars grown in four distinct environments in Greece. Field trials were conducted in ten independent commercial fields per cultivar within each environment, with four samples collected from each field. Seed quality traits were analyzed using recommended official methods, and the Stability Index (SI) was calculated for each trait to quantify consistency across environments and cultivars. Traits such as 1000-seed weight, oil, and crude protein exhibited more consistent expression across environments and cultivars, whereas crude fiber and moisture showed substantial variation in stability across environments and cultivar × environment combinations, reflecting strong genotype × environment effects. Evaluation of relationships between traits revealed significant positive associations between 1000-seed weight and oil, and between crude protein and ash, as well as negative associations between 1000-seed weight and moisture and between crude protein and oil, indicating potential trade-offs among seed traits. Principal component analysis further highlighted trait associations and variability patterns across genotypes and environments. Overall, the combined use of Stability Index assessments and multivariate analyses provides a robust descriptive framework for evaluating cultivar performance and supporting cultivar selection under diverse agro-ecological conditions.

Caught Between Vulnerability and Neglect: Nutrition in People with Intellectual Disabilities

by Ellen Margrete Iveland Ersfjord, Helen Kathrine Røstad-Tollefsen, Svein Olav Kolset and Arlene M. McGarty

Nutrients 2026, 18(2), 304; https://doi.org/10.3390/nu18020304 (registering DOI) - 18 Jan 2026

Abstract

People with intellectual disabilities are disproportionately affected by diet-related health inequalities. This Perspective outlines a dual challenge: (1) intrinsic vulnerabilities—cognitive limitations, health-literacy constraints, and comorbidities—that impair individuals’ ability to make healthy dietary choices, and (2) extrinsic neglect—insufficient support in care environments, inadequate nutrition-related training among informal caregivers and support staff, and structural gaps in policy and services. We argue that this “double jeopardy” undermines nutritional equity and proposes strategies for person-centered nutrition education, caregiver empowerment, supportive food environments, and inclusive policy frameworks. Greater interdisciplinary collaboration and tailored research are urgently needed to ensure nutritional health as a right for people with intellectual disabilities. Full article
