In this article, we investigate an intelligent ground penetrating radar (GPR) that facilitates root-zone soil moisture estimation, a key parameter in precision agriculture. To create an intelligent GPR, we must train machine learning (ML) methods applied to the GPR-received signal. This process requires a large number of labeled GPR data that would be time-consuming and labor-intensive if created via field measurements. This article uses gprMAX software to emulate drone-coupled GPR received signal to generate large-scale data for training ML models. The data are created via a 1.5 GHz Ricker waveform considering a three-layer soil consistent with a realistic soil horizon model. The approach is structured as follows: first, we generate a synthetic dataset using gprMAX. Feature engineering techniques are then employed to extract meaningful components from the GPR signals, followed by a rigorous selection process to identify the most effective ML model for soil moisture prediction. Finally, we validate our model by integrating synthetic data with real GPR data collected at the SoilX lab at Worcester Polytechnic Institute, enhancing prediction accuracy and generalization capability. Our proposed model achieves an overall average root-mean-squared error of 0.5%, and 1.56 cm for moisture and depth estimations, respectively. The proposed intelligent GPR, when installed on a drone, enables high horizontal (e.g., 10 m) and vertical (e.g., 1.5 cm) resolution and high penetration depth (beyond 2 m) megafarm root-zone 3-D moisture map creation. Thus, it offers much higher capabilities when compared to traditional methods, such as synthetic aperture radar and satellite imaging. These results facilitate efficient farming practices, such as optimizing irrigation models, for better crop yields and food security. © 2023 IEEE.

The development of agricultural biostimulants (BS) has marked a significant advancement in bolstering crop resilience against environmental stressors. This study investigates synthesizing and applying six novel nano-based potassium (K)-enriched biostimulants that enhance micronutrient availability, nitrogen uptake, and subsequent plant growth during seed germination and developmental phases. Using Nuclear Magnetic Resonance (NMR) and Fourier-transform infrared Spectroscopy (FTIR), the synthesized biostimulants were characterized before their application in soil-supporting wheat (Triticum aestivum L.) cultivation. The biostimulants’ effects at three concentrations (0.1, 0.2, and 0.5 mmol) and were evaluated on physiological and biomolecular parameters. To assess nutrient availability, soil mineral content was analyzed via X-ray Photoelectron Spectroscopy (XPS). An increase in biostimulant concentration led to a marked rise in seed germination rates, correlating with elevated bioavailability of nitrates, ammonia, sulfur, potassium, and other key micronutrients. At a threshold concentration of 0.2 mmol, a notable improvement in the bioavailability of nutrients and a significant increase in the total phenol and flavonoid content was observed. The phenolic content was measured using the Folin-Ciocalteu method and expressed as Gallic Acid Equivalents (GAE), while flavonoids were quantified based on quercetin equivalents. These phytochemicals were correlated with enhanced antioxidant activities, measured using the Ferric Reducing Antioxidant Power (FRAP) assay. The results indicated an 80% increase in antioxidant capacity, particularly for biostimulant BS6 at the 0.2 mmol concentration. Furthermore, biostimulants demonstrated a positive effect on the elongation of radicles and plumules, contributing to improved plant vigor. Overall, the study highlights the potential of synthesized K-based biostimulants to significantly enhance crop productivity, nutrient uptake, and antio

Neuropeptides configure the feeding network of Aplysia. For example, egestive activity is promoted by small cardioactive peptide (SCP), and ingestive activity is promoted by a combination of feeding circuit activating peptide (FCAP) and cerebral peptide 2 (CP-2). In addition, SCP and FCAP/CP-2 have a common network effect that does not contribute to motor program specification. They increase the excitability of an interneuron, B63. In this report, we further characterized the effects of peptides on B63. We performed voltage-clamp experiments and used a step protocol to look at steady-state currents. We found that SCP and FCAP/CP-2 both induced an inward current that was virtually absent in low-sodium saline. Previous work has established that B63 is unusual in the feeding circuit in that subthreshold depolarizations are autonomously generated that can trigger motor programs. Here, we show that this autonomous activity is more frequent in the presence of peptides. Previous studies have also shown that activity of the feeding central pattern generator (CPG) can be initiated by neurons that excite B63, e.g., by cerebral buccal interneuron 2 (CBI-2), a projection neuron that triggers biting-like motor programs. Here, we show that the latency of CBI-2-induced activity is decreased by stimulation of the esophageal nerve (EN) (which releases endogenous SCP). These results, taken together with previous results, indicate that peptides that act divergently to configure network activity additionally act convergently to promote motor program induction. We present data that suggest that this arrangement facilitates brief switches between ingestive and egestive motor activity. © 2025 The Authors.

A queue in health facilities happened when the service capacity is limited, while the patients keep arriving and then waiting. In many cases, besides waiting, customers can be rejected from the system (balking). This case was considered as the cause of the daily positive cases of COVID-19 patients in Arcamanik Sub City Area (SCA). This observation was conducted from September 17, 2020 to February 4, 2021. Arcamanik SCA was frequently included in one of the highest positive cases of COVID-19 in Bandung City, West Java, Indonesia. The server used was the number of beds in Hermina Arcamanik Hospital, the referral hospital in the observed area. The method used a discrete event simulation, with an Erlang B queuing model (G/M/c):(FIFO/c/∞). The more the servers, the more chances the patients being rejected would converge to zero. The minimum required bed was 32 beds, hence patients who come were not rejected. Meanwhile, the rejected patients can visit another hospital as an alternative, one of which is Hasan Sadikin hospital (Rumah Sakit Hasan Sadikin/RSHS) as the central hospital of Bandung City. The proportion of beds for patients from Arcamanik SCA was 0.16 times the excess empty beds. For patients to receive treatment at the two hospitals, the number of COVID-19 cases must not exceed 62 cases. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

Aquaculture and Fisheries 2024年第2期10卷 171-182页

The accelerated growth of global aquaculture has boosted the production chain of Nile tilapia (Oreochromis niloticus), currently the third most cultivated species worldwide. This fish plays a crucial role in global food security. Protein is the main fish diet nutrient, and its quality, as well as protein level variations, directly and significantly affect the productive chain of this species. In this study, we conducted a comprehensive review of protein requirements at different tilapia development stages, underscoring the fundamental importance of a balanced diet to promote efficient growth. The study identified protein requirement variations based on weight, age, and different tilapia farming systems. In addition, the challenges associated with formulating balanced diets are discussed, especially in the face of the scarcity of traditional protein sources, such as fishmeal. Several factors are considered in this review, including tilapia development stage, rearing system, stocking density, ingredient quality, specific tilapia nutritional requirements and strains, feed management, temperature, and water quality. A gradual decrease in protein requirements is observed as fish grow and reach a minimum point during the growth phase, followed by a slight increase during the subsequent fattening phase. Tilapia protein requirements are influenced by various factors, including growth phase and farming system characteristics. Identifying the ideal protein levels at each stage is crucial for guiding sustainable tilapia aquaculture practices and enhancing the overall production efficiency of the species. © 2024 Shanghai Ocean University.

Inventory management in the health sector, specifically in the pharmaceutical service, represents a high percentage of logistics costs, putting pressure on health institutions to optimize inventory management to guarantee the availability of supplies. On the other hand, different regulations worldwide establish the adoption of mechanisms and policies for adequate inventory management, a situation that in low- and middle-income countries is restricted by resource limitations and the low implementation of robust techniques and methodologies. Different applications of models for inventory management have been identified in the literature, such as optimization models, Lean tools, and multicriteria decision-making methods. However, integrated approaches to optimize demand management, ordering, and controlling pharmaceutical services supplies are still under development. Therefore, the present study proposes a three-phase hybrid approach based on MCDM techniques and data analytics to improve inventory management of the pharmaceutical service in a health research center. The first stage consisted of characterizing the process to identify aspects for improvement. In the second stage, a multicriteria ABC classification model based on F-AHP and TOPSIS was applied to classify laboratory supplies for three selected clinical studies. Furthermore, the appropriate forecasting method was chosen for each clinical study, and a combined model (P model and FEFO model) was applied to establish the reorder point. Then, strategies, mechanisms, and policies were proposed to improve inventory management and redesign the process flow. As the main results, a multicriteria ABC method was obtained to classify laboratory supplies, taking into account Rotation (GW = 0.512), Criticality (GW = 0.286), and Availability (GW = 0.203). On the other hand, through data analysis and regression models, the exponential smoothing model with α = 0.10 was identified as the most convenient forecasting model, as

Polymer Composites 2024年第16期45卷 15159-15172页

作者： Nugroho, Roshid Adi Saputra, Ozi Adi Pradita, Agung Lucky Fajar, Al Bukhori Nur Wibowo, Fajar Rakhman Department of Chemistry Faculty of Mathematics and Natural Sciences Universitas Sebelas Maret Central Java Surakarta Indonesia Sustainable Chemical Science and Technology Taiwan International Graduate Program Academia Sinica Taipei Taiwan Institute of Chemistry Academia Sinica Taipei Taiwan Department of Chemical Engineering Collage of Engineering National Taiwan University Taipei Taiwan

Polymer technology has rapidly advanced across diverse domains, particularly in biomedical applications. Among various polymers, polyurethane (PU) hold great potential in developing biomaterials such as biomedical scaffold and drug delivery. In this study, we have innovatively engineered eco-friendly polyurethane using lignin, a sustainable bio-polyol derived from oil palm empty fruit bunches. To enhance the physicochemical properties of the PU, we have incorporated hydroxyapatite (HA) into the composites. The inclusion of HA has led to notable improvements in crucial properties such as density, porosity, and water absorption, making these composites ideal candidates for tissue regeneration scaffolds. Furthermore, to assess their biomedical applicability in drug delivery and cell scaffolding, we have employed the quercetin drug model. The results revealed a sustained kinetic release behavior within the polyurethane/hydroxyapatite (PU/HA) composites, showcasing their potential for controlled drug delivery applications. Moreover, cytotoxicity assays conducted using neuro-2a cell models demonstrated the non-cytotoxic nature of both PU and PU/HA composites. This finding holds significant implications for biomedical applications, indicating that these composites offer biocompatible platforms for tissue engineering and regenerative medicine endeavors. The ability of these composites to support cell viability underscores their potential for a wide range of biomedical applications, including neural tissue engineering and drug delivery systems targeting brain diseases. These findings pave the way for the development of innovative and sustainable biomaterials with diverse biomedical applications. Highlights: An eco-friendly polyurethane has been engineered by harnessing liginin-derived oil palm empty fruit bunches. Incorporation of hydroxyapaptite enhance the physical properties of polyurethane. Controlled kinetic drug release is one of polyurethane/hydroxyapatite (PU/HA) com
