Published: April 2024

AbstractTo verify the effectiveness of the intelligent decision method for fertigation, an automatic control system for fertigation in greenhouses was designed, and three intelligent decision methods based on evapotranspiration (T1), soil moisture (T2) and accumulated temperature (T3) were tested. Intelligent decisions included monitoring meteorological information, automatically monitoring soil moisture, utilizing fertigation application systems and using automated control modules. The system was stable and accurately controlled according to the decision scheme. The results showed that the average errors of the automated control system for decision‐making and irrigation were 1.1 and 0.8%, respectively. The study findings serve as a reference for the integration of intelligent irrigation decision‐making and control systems and for further improving the efficiency of water and fertilizer utilized. Compared with those of the control, the three intelligent decision‐making methods increased the tomato yield by 8, 12 and 7%, respectively. In addition, the irrigation water and fertilizer levels decreased significantly compared with those in the control treatment. Although the accuracy of the soil water content (SWC) estimated based on ET and temperature in irrigation decision‐making is low, the general trend is consistent with practice. In addition, the irrigation water use efficiency (IWUE) and partial factor productivity of fertilizer (PFP) were significantly improved. Similarly, the IWUE in T1 was the highest (60 kg m⁻3), and the PFP in T3 was the highest (669 kg kg⁻¹).

Published: April 2024

AbstractPredictive genetic testing is increasingly available for individuals with a heightened risk of motor neuron disease (MND). However, little is known about how they decide whether or not to get tested, and how they experience this process. This paper reports findings from a constructivist grounded theory‐informed interview study with 24 family members of people with identified or suspected inherited MND (iMND). Fourteen did not know their genetic status, and nine had decided to have predictive testing, of whom six tested positive for the pathogenic gene variant identified in their family and three tested negative. One additional person was identified as negative through a parent's negative result. This paper explores the diverse ways people approached testing, and the many factors and motivations involved, based on personal attitudes and goals, experiences of living with genetic risk, and wider family considerations and circumstances. Results were met with a range of emotions; whatever the outcome, the news disrupted each person's view of the future, and they adapted in their own way and time. Support after results was variable and a perceived lack of support impacted coping and the ability to move forwards. This paper situates findings against literature on other genetic conditions, highlighting experiences as grounded in the unique characteristics of iMND. Thus, it emphasizes the need for disease‐specific guidelines and support structures around predictive genetic testing in this context. Understanding people's experiences and responding to these needs is particularly timely given the uptake of testing amongst this group is anticipated to rise with increasing access to genetic testing for people with MND, and gene‐specific clinical trials.
Fentanyl's potential impact on public health in India and China: A comparative review
Authors: Lassi Nicholas 
Published: April 2024

AbstractThis study reviewed and compared fentanyl's potential impact on public health in India and China, two nations linked to its production and distribution. A comparison of China and India's governance structures, historical experiences with opioids, ideologies, and drug policies on the potential for domestic fentanyl use showed that fentanyl will likely become a more significant threat to Indian society. India's relatively weak governance, historical acceptance of opium, and permissive drug culture facilitate an environment conducive to the production and use of fentanyl. In contrast, China's strong central government, the Opium Wars, the historical effects of opium addiction, and adherence to conservative Confucian ethics will likely contribute to opposition to fentanyl use. Understanding these disparities is paramount for policymakers and public health officials in both nations to develop and customise strategies to confront the challenges posed by fentanyl.

Published: April 2024

AbstractALG1‐CDG is a rare, clinically variable metabolic disease, caused by the defect of adding the first mannose (Man) to N‐acetylglucosamine (GlcNAc2)‐pyrophosphate (PP)‐dolichol to the growing oligosaccharide chain, resulting in impaired N‐glycosylation of proteins. N‐glycosylation has a key role in functionality, stability, and half‐life of most proteins. Therefore, congenital defects of glycosylation typically are multisystem disorders. Here we report a 3‐year‐old patient with severe neurological, cardiovascular, respiratory, musculoskeletal and gastrointestinal symptoms. ALG1‐CDG was suggested based on exome sequencing and Western blot analysis. Despite her severe clinical manifestations and genetic diagnosis, serum transferrin glycoform analysis was normal. Western blot analysis of highly glycosylated proteins in fibroblasts revealed decreased intercellular adhesion molecule 1 (ICAM1), but normal lysosomal associated membrane protein 1 and 2 (LAMP1 and LAMP2) expression levels. Glycoproteomics in fibroblasts showed the presence of the abnormal tetrasacharide. Reviewing the literature, we found 86 reported ALG1‐CDG patients, but only one with normal transferrin analysis. Based on our results we would like to highlight the importance of multiple approaches in diagnosing ALG1‐CDG, as normal serum transferrin glycosylation or other biomarkers with normal expression levels can occur.

AbstractIn this study, hindcasts from eight Copernicus Climate Change Service (C3S) and three North American Multi‐Model Ensemble (NMME) operational seasonal forecast systems, based on dynamical climate models, are employed to investigate the influence of the South Atlantic Ocean Dipole (SAOD) on the predictive skill of Central Africa (CA) rainfall. The focus is primarily on the June–July–August season for 1993–2016. The findings reveal that, when regionally averaged, all models exhibit positive skill in predicting CA rainfall, except for the Geophysical Fluid Dynamics Laboratory (GFDL‐SPEAR) model. Notably, there are significant spatial variations in skill across different regions. Model performance is particularly low (high) in the Central African Republic and Congo Basin (Gabon and Chad) and tends to deteriorate with increasing lead‐time. Models that demonstrate a strong connection between SAOD and CA rainfall tend to exhibit better predictive skills in forecasting rainfall, in contrast to models with weaker connections. This leads to a significant in‐phase relationship between the predictive skills of rainfall and the strength of the SAOD–rainfall connection among the models. Furthermore, the atmospheric circulation responding to SST forcing associated with the El Niño–Southern Oscillation exerts a significant influence on the robust atmospheric circulation associated with the climatological mean of SST over the SAO. This suggests that mean state bias in the SAO/equatorial Pacific region plays a role in modulating the strength of the simulated SAOD–CA rainfall connection and, consequently, the prediction skill of CA rainfall. In general, both NMME and C3S models appear to be valuable tools capable of providing essential seasonal information several months in advance. These insights can aid decision‐makers in the region in making informed decisions regarding adaptation and mitigation measures.
Spatiotemporal variability of the rainy season in the Yucatan Peninsula
Authors: Romero David , Alfaro Eric J. 
Published: April 2024

AbstractThe rainfall regime is a critical factor in the Yucatan Peninsula, as the spatial and multiannual variability of rainfall is a major concern, particularly for crops. Variability in the rainy season was examined considering the onset and demise of the annual rainy season, the total rain volume, the rainfall season duration and the intense precipitation events recorded in meteorological stations (1978–2020). We analysed individual time series and calculated the long‐term trend. Additionally, we explored the relationship between each summer rainfall characteristic and several oceanographic indices using multivariate techniques. We also developed a Trans‐Isthmic Index from the relationship between the El Niño–Southern Oscillation and the Atlantic Multidecadal Oscillation. This index allows for determining the effect of the overall influence of the ocean on climate. The timeseries analysis revealed a high interannual variability and long‐term positive trends concerning the duration of the rainy season with earlier onset and later demise, and the total rainfall volume and also a positive trend for the occurrence of heavy precipitation suggesting a shift in intra‐annual patterns. Spatially, the analysis revealed clusters of stations with a similar variation, probably related to the AMO, NIÑO3.4 or TII indices. The spatial pattern was confirmed by analysing CHIRPS gridded precipitation data. Our results show that wetter conditions are associated with lower temperatures in the equatorial Pacific and warmer conditions in the Atlantic.

AbstractObjectivesPrior studies on the psychological well‐being in pediatric inflammatory bowel disease (PIBD) have reported controversial results. Our aim was to compare the psychological well‐being and lifestyle factors in patients with PIBD and their controls and to assess the role of contributing disease characteristics.MethodsThis cross‐sectional study included 60 PIBD patients aged 6−17 years (26 with Crohn's disease [CD], 34 with ulcerative colitis [UC] or unclassified colitis [IBD‐U]) from two university hospitals in Finland, and their age‐ and sex‐matched healthy controls. Psychological well‐being was assessed with three measures: a questionnaire on overall psychological well‐being (PSWB) and for adolescents also Beck Depression Inventory (BDI Ia) and Perceived Stress Scale (PSS). In addition to disease characteristics and pain, we assessed physical activity, sleep, screen time, and social well‐being.ResultsControls were more likely of stressing more (odds ratio [OR] = 3.67, 95% confidence interval [95% CI] 95% CI = 1.02−13.14), but other measures of psychological well‐being did not differ statistically significantly between patients and controls. In CD, a clinically more active disease associated with inferior psychological well‐being in adolescents (BDI [ρ = 0.63, p = 0.021], PSS [ρ = 0.70, p = 0.008], PSWB [ρ = 0.56, p = 0.049]). Longer time from diagnosis correlated with better psychological well‐being on BDI (ρ = −0.39, p = 0.024) and PSS (ρ = −0.38, p = 0.034). Lifestyle was more sedentary in PIBD (less physical activity in children OR = 0.82, 95% CI = 0.68−0.99 and more screen time in adolescents OR = 1.18, 95% CI = 1.00−1.40).ConclusionAlthough the clinical features of PIBD are potentially a burden for psychological well‐being, many young patients cope well with their disease. Individual variation in well‐being is remarkable, making supportive measures challenging.

AbstractBACKGROUNDThe wild variety Fritillaria taipaiensis E.B (EB) is known for its superior therapeutic effects, but its limited production cannot meet demand. As a result, the cultivated variety F. taipaiensis P. Y. Li (PY) has been widely grown. In this study, we conducted a comprehensive analysis comparing EB and PY in terms of external features, sipeimine content, metabolome and chloroplast genome to differentiate these two varieties.RESULTSOur research revealed that the petals and pods of EB are green, while those of PY have purple markings. The bulbs of EB contain significantly higher levels of sipeimine compared to those of PY. Metabolomic analysis identified 56 differentially expressed metabolites (DMs), with 23 upregulated and 33 downregulated in EB bulbs. Particularly, 3‐hydroxycinnamic acid and secoxyloganin may serve as distinctive DMs. These DMs were associated with 17 KEGG pathways, including pyrimidine metabolism, alanine, aspartate and glutamate metabolism, and galactose metabolism. Differences in the length of the chloroplast genome were primarily observed in the large single‐copy (LSC) region, with the largest variation in the trnH‐GUC–psbA region. The placement of the trnH gene and the rps gene in proximity to the LSC/IRb boundary differs between EB and PY.CONCLUSIONThe results of this study provide valuable insights for the introduction and comprehensive development of wild F. taipaiensis from a scientific perspective. © 2024 Society of Chemical Industry.

AbstractAlthough microbiomes associated with plants and the environment are intricately intertwined, it remains unclear how various environmental scales affect these relationships differently. We employed high‐throughput amplicon sequencing to examine the plant‐associated bacterial and fungal communities across three different micro‐habitats (leaf, root, and root zone soil) in 16 shrubs distributed across a >500 km transect of the eastern Qinghai‐Tibetan Qaidam Basin. Among the three microhabitats, the diversity and composition of plant‐associated bacterial and fungal communities differed significantly. Although micro‐habitats play a crucial role in shaping plant‐associated microbial communities, geographic and climatic variables largely influenced the community compositions across the three micro‐habitats. Notably, the microbial communities in all three micro‐habitats showed significant distance‐decay patterns. Furthermore, fungi exhibited less variation across the three microenvironments, and were more sensitive to environmental changes than bacteria. Moreover, microbiome complexity and stochasticity gradually increased from soils to roots and finally to leaves. The microbial communities in soils and epiphytes (leaves and roots) were predominantly shaped by determinism and stochasticity, respectively. These results highlight that plant‐associated microbiomes are primarily shaped by the microenvironments associated with plants; however, their compositions, dynamics, and assembly are further influenced by geographic and climatic factors. Overall, our findings greatly increase our understanding of the intricate dynamics between plant‐associated microbiomes and their surrounding environment in drylands. This knowledge contributes to ongoing research on microbial ecology and provides substantial supports for the precise evaluation of desert ecosystem function. The findings are helpful for biodiversity conservation and sustainable management of desert shrublands.
How does ski infrastructure change soil erosion processes on hillslope?

Published: April 2024

AbstractSki tourism's popularity is driving a rise in the number of ski resorts. This study aims to present the impact of ski infrastructure on soil erosion processes in the example from a small catchment in the Gubałowskie Foothills in southern Poland, where landscape changes before (since 1879) and after the construction of the ski station (2007) are presented. The analyses of changes in flow accumulation, slope morphometry, and drainage ditches were conducted in the test area. Quantitative analyses were performed using repeated DEMs derived from aerial LiDAR survey and detailed geodetic measurements, complemented by geomorphological mapping done in the field. The study has revealed that the ski infrastructure has not only directly transformed the hillslope by flattening and constructing escarpments (up to 3 m high) but has also created alternating patterns of erosion and accumulation. In the test area, the drainage ditch was poorly designed. It was filled with materials (0.1–0.5 m), and two new outlets formed. The escarpment of the analyzed ski run has been diminished by 0.5 m. An alluvial fan (0.1–0.22 m thick) has developed on the flattened surface below the escarpment with drainage ditch outlets. This fan is eroded by subsurface flow that creates a piping system. The gully below the alluvial fan has retreated upslope, accelerated by subsurface erosion. This study enables the presentation of hillslope adjustments and processes in response to the new conditions caused by ski infrastructure. Such results may support more effective land management in regions changed by ski infrastructure.

AbstractThe impact of climate warming on coastal benthic fauna is already observed, but forecasting their long‐term fate remains challenging. This study uses δ18Oshell data of specimens of five bivalve species collected at six locations and results from kilometer‐scale atmosphere–ocean climate model for the time intervals of 1987–2017 and 2070–2100, to estimate changes in bivalve growth phenology. All species will benefit from climate warming during winter, experiencing a longer growing season than currently. The growth of Aequipecten opercularis, Flexopecten glaber, and Pecten jacobaeus will decrease in summer, resulting in up to 3 months of reduced growth per year. Glycymeris pilosa and Venus verrucosa in the southern Adriatic Sea will be more affected than those in the north, with up to 4 months longer annual growth. These findings can inform adaptation plans for bivalve management in the Adriatic Sea but also in areas where the studied species are present.
Weakening Indian Ocean carbon uptake in 2015: The role of amplified basin‐wide warming and reduced Indonesian throughflow
Authors: Liao Enhui , Lu Wenfang , Xue Liang , Du Yan 
Published: April 2024

AbstractIn 2015, the Indian Ocean exhibits an exceptionally weakened CO2 uptake, highlighting strong interannual variability of ocean carbon sink. By utilizing multiple ocean CO2 partial pressure (pCO2) data and a state‐of‐the‐art ocean biogeochemical model, we show that the 2015 ocean CO2 anomaly is characterized by a basin‐wide amplification of ocean pCO2, differing from ocean pCO2 responses to other Indian Ocean Dipole events (e.g., 1997 and 2019). The distinct ocean pCO2 anomaly is attributed to an amplified warming and an unprecedented weakening Indonesian Throughflow under the influence of co‐occurrence of positive IOD and extreme El Niño in 2015. The amplified warming drives higher ocean pCO2 in the western and central Indian Ocean, while the ITF transports anomalously high ocean pCO2 water from the Pacific Ocean to the southeastern Indian Ocean. This newly identified ocean carbon response provides deeper insights into the Indian Ocean carbon interannual variability.

Published: April 2024

AbstractTracking polarization in real‐time is a long‐term challenge. The conventional heuristic and gradient‐descent‐based algorithms for polarization tracking lack efficiency and interpretability. To resolve the problem, a white‐box digital twin modeling the entire polarization tracking system is derived by calculating with Stokes vectors and Mueller matrices. Moreover, the real‐time polarization tracking enabled by the white‐box digital twin is experimentally demonstrated, which is over 7 times faster than the commonly used stochastic parallel gradient descent (SPGD) on average. The adoption of digital twin allows the algorithm to bypass the loop of perturbation, sampling, and adjusting over the real system, thereby significantly reducing the sample times and recovery time. The proposed white‐box digital‐twin‐based algorithm has strong interpretability and high efficiency, which has substantial potential to become a standard approach to achieve real‐time polarization tracking.

AbstractAs a powerful platform for next‐generation display, planar liquid crystal (LC) optics exhibit attractive properties such as electro‐optical response, high efficiency, and broadband tunability. With planar LC optics applications taking off, multidimensional modulation and multiplexing capability of light wave is becoming crucial. Here, a Pancharatnam‐Berry phase LC hologram is demonstrated that enables the multidimensional modulation of amplitude, phase, and polarization of light, which increases the degree of freedom of multiplexing display to 4 at a single wavelength, realizing the simultaneous decoupling modulation in dual polarization channels in near and far fields. According to the quaternary degeneracy characteristics of the orientation angle of LC molecules implied in Malus' law, the LC holograms are designed using the optimized Gerchberg‐Saxton and annealing algorithms, and it is demonstrated that the spatial and polarization multiplexing of LC holograms have remarkable wavelength‐dependent electrical tunability. This LC hologram paves a promising pathway toward multifunctional LC optics for advanced display and imaging.
