Abstract
Treatment of tailwater in intensive aquaculture has been a major issue that affects the utilization efficiency and pollution of water resources. In this study, the intensive farming of bullfrogs (Rana catesbeiana) was taken as an example to construct a tailwater treatment system consisting of a flotation tank, a biochemical tank and wetlands. The operating conditions of the biochemical tank were first optimized. The results showed that at an influent flow rate of 250 m3·h− 1, a hydraulic retention time of 6 h, and an aeration intensity of 2000 m3 h− 1, the levels of CODCr, ammoniacal nitrogen and total phosphorus in the effluent of the biochemical tank were reduced by 70%, 43% and 42%, respectively. Under these operating conditions, the efficiencies of the flotation tank, biochemical tank and constructed wetlands were 8.3%, 67.3% and 5.6% for CODCr removal, 4.2%, 40.4% and 70.5% for ammoniacal nitrogen removal, and 16.8%, 42.1% and 59.4% for total phosphorus removal, respectively. After one month of continuous operation, the following treatment results were obtained: 71.7% and 90% removal for CODCr and BOD5, 83% and 92% removal for ammoniacal nitrogen and nitrite nitrogen, 86.7% and 76.5% removal for reactive phosphorus and total phosphorus, and 95.1% removal of suspended solids. The dissolved oxygen level increased from 1.2 mg·L− 1 (influent) to 3.5 mg·L− 1 (effluent), indicating significantly improved water quality that met the Grade 1 national wastewater discharge standard and the criteria of recycled water utilization in bullfrog farming. This system thus realized the regeneration and utilization of tailwater in intensive aquaculture.

Abstract
Appropriate determination of actual evapotranspiration (ETa) is crucial to improve crop water productivity and optimizing water resource consumption. Satellite data enables us to calculate ETa for a large spatial extent with higher granularity, but the temporal frequency of non-commercial satellite data is often a limitation. This research proposes a method that combines crop coefficients with satellite data to fill temporal data gaps and calculate ETa on a daily basis. The study was conducted on sugarcane crops in the Amirkabir Agro-industries area in the southern part of Khuzestan Province, southwestern Iran. First, Landsat-8 data with the 8- day temporal resolution is acquired to estimate Land Surface Temperature (LST) using Single-Channel Algorithm. The estimated LST is validated with the in-situ canopy temperature measurement via Infrared Thermometer (IRT). Then, the validated LST is used to predict the crop stress coefficient (Ks) based on its relationship with the crop water stress index (CWSI). The crop coefficient (Kc) is obtained from the Surface Energy Balance Algorithm for Land (SEBAL) algorithm. The predicted Ks and Kc with the 8-day temporal resolution are assumed to be constant during the eight days and are utilized to calculate daily ETa by multiplying by the daily reference evapotranspiration (ET0) obtained from local meteorological data. The calculated Ks based on the LST result showed that nRMSE ranged from 0.03 to 0.07 from April to September. The results indicate that the crop coefficients of sugarcane in the initial and mid-stage are 12% and 18%, respectively, higher than the proposed figures by the FAO56 guideline. The aggregated decadal and monthly ETa have shown remarkable similarity with the WaPOR datasets, represented by an RMSE of 8.7 and 1.93 mm, respectively. We think this naval approach can significantly overcome the challenge of remote sensing data availability with the desired higher temporal resolution.
A Lightweight Clock Synchronization Technique for Wireless Sensor Networks: A Randomization-Based Secure Approach
Authors: Kara Mostefa 
Published: January 2023

Abstract
Wireless sensor networks (WSNs) are receiving significant attention. In which, there is a large number of studies are being done to address the problem of clock synchronization; where an adversary attacks a node and it can prevent the network from running certain clock-based applications. Due to the low capacity of wireless sensors, we propose in this article a new technique to synchronize the nodes of a system, through the random selection of a subset of neighbors instead of taking into account all the neighbors. Thanks to the proposed technique, we reduce the influence of malicious nodes, reduce the storage space, computation time, and energy consumption.

The results indicate that sprinkler range with nozzle diameter, working pressure, Installation Heights, spray elevation angle, discharge coefficient, wind direction and speed, water flow regime, and droplet motion in air was in highly significant correlation, the sprinkler range Progressive decreases around the sprinkler along the sprinkler range direction, as well increases by 5.2342%~10.6278% in the downwind direction and decreases by 4.6897%~9.8623% in the headwind direction compared with no wind. The wind speed increases, then the range decreases, and the wind direction shifts, then the range shifts, so the wind direction wind speed changes then the range changes. The coefficients of determination, the consistency Index, the root mean square error, absolute error, relative error between calculated Values and Measured Values of computational models are 0.9146, 0.9205, 8.7748%, 10.4980%, 8.2524% and 8.1421%, respectively. The smaller coefficients of determination and the consistency Index of calculated Values and Measured Values of computational model under windy conditions comparing with no wind, as well the larger root error, deviation, absolute error and relative error. The calculation model in this paper has a clear principle, comprehensive influence factors, complete physical meaning, high calculation accuracy, small error, and wide applicability. This calculation model can effectively reflect the nozzle range change law. This study provides theoretical basis for determining the sprinkler hydraulic performance and provides technology support for Planning and Design of sprinkler irrigation system.

Abstract
Follistatin-like 1 (FSTL-1), a secreted glycoprotein, is upregulated in the serum of patients with acute kidney injury. However, it is unknown whether it protects against renal ischemia-reperfusion (I/R) injury. Our present study found that treatment with FSTL-1 (100 mg/kg) intravenous injection alleviated renal injury, as evidenced by reduced serum creatinine (Scr) and blood urea nitrogen (BUN) levels, along with reduced histopathological kidney damage. Moreover, FSTL-1 treatment reduced the number of apoptotic cells and the accumulation of reactive oxygen species (ROS) during I/R injury. The protective effect of FSTL-1 was via AMPK/PPAR-δ pathway, because, after blockade of AMPK/PPAR-δ pathway by individual inhibitor (GSK0660, a PPAR-δ antagonist, or compound C, an AMPK inhibitor), the protective effects of FSTL-1 on oxidative stress and apoptosis were blocked. Taken together, our results reveal that FSTL-1 attenuates renal I/R injury by inhibiting apoptosis in renal tubular epithelial cells, which is meditated by activating AMPK/PPAR-δ pathway.

Authors: Liao Xiaozu , Chen Xiaojuan , Zhong Shi , Wen Junlin , Li Binfei 
Published: January 2023

Abstract
Massive pulmonary embolism (PE) is a life-threatening complication of major surgery with a mortality rate of up to 50%. Extracorporeal membrane oxygenation (ECMO) is primarily used for respiratory and circulatory support. Venoarterial extracorporeal membrane oxygenation (VA-ECMO) was used to stabilize patients with acute massive PE. Acute brain injury, vascular disease, and immunosuppression, as proposed in the 2021 ELSO guidelines, are contraindications to ECMO. We report a case of a patient with craniocerebral trauma whose postoperative course was complicated by massive PE and subsequent cardiac arrest that required emergent VA‐ECMO, followed by anticoagulation with heparin. The patient showed hemodynamic improvement. The patient was discharged 68 days after hospitalization.

Published: January 2023

Abstract
The household expenditure patterns and the factors related to them caught the attention of policymakers for social programs. Household consumption is the key component for living standards and a good economy. The objective of this research is to estimate the factors influencing household expenditure patterns concerning household residence area for each household on basis of the social-economic as well as demographic factors. The data was obtained from the Fifth Integrated Household Living Conditions Survey (EICV 5) 2016/2017. The neural network method has been used in the analysis of the data. The results on household characteristics and component expenditure, independent variables play a crucial role in discriminating the household expenditure categories i.e low and high expenditure in Rwanda. The component expenditure analysis on rural and urban residence areas revealed that there is a disparity between rural and urban residential areas. In rural residence areas, the household expenditure is significantly estimated by Household assets (durable goods), food, and household size while in the urban residence area, the household expenditure is significantly estimated by Household assets (durable goods), non-food, and education costs. When the residence area is taken as an explanatory variable, the order of importance has been changed as follows Household assets (durable goods), non-food, education cost, food, household size, and Age. All independent variables considered in this study are important in estimating household expenditure.

Abstract
The “Tian Di Chang Chun” horizontal plaque inscribed by the general Feng Yü-hsiang in R.O.C. 25 (1936) shows his patriotic, compassionate, fair, and just thoughts and ideals. It has significant educational value for contemporary society. However, due to the aging of the materials and some factors in the preservation environment, the coloured decorative coating on the surface of the plaque has shed. The digital microscope system, scanning electron microscopy-energy dispersive spectroscopy (SEM-EDS), X-ray diffraction (XRD) and micro-Fourier transform infrared spectroscopy (µ-FTIR) were used to analyse the materials and techniques used on this plaque. It has been showed that the decorative layer of the plaque consists of a red Chinese lacquer film layer on the surface and a ground layer. The red lacquer film layer comprises Chinese lacquer, tung oil, and cinnabar. The materials used for the ground layer are the blood putty made of the blood product, youman (flour-oil-lime mixture), and brick powder. The technique used is the SDH (San Dao Hui) layer technique in ancient buildings. This study provides physical evidences regarding the materials and techniques used in inscribed plaque relics, and also provides technical supports to further protect and restore the plaque.
DeFi: data-driven characterisation of Uniswap v3 ecosystem &amp; an ideal crypto law for liquidity pools
Authors: Miori Deborah , Cucuringu Mihai 
Published: January 2023

Abstract
Uniswap is a Constant Product Market Maker built around liquidity pools, where pairs of tokens are exchanged subject to a fee that is proportional to the size of transactions. At the time of writing, there exist more than 6,000 pools associated with Uniswap v3, implying that empirical investigations on the full ecosystem can easily become computationally expensive. Thus, we propose a systematic workflow to extract and analyse a meaningful but computationally tractable sub-universe of liquidity pools. Leveraging on the 34 pools found relevant for the six-months time window January-June 2022, we then investigate the related liquidity consumption behaviour of market participants. We propose to represent each liquidity taker by a suitably constructed transaction graph, which is a fully connected network where nodes are the liquidity taker’s executed transactions, and edges contain weights encoding the time elapsed between any two transactions. We extend the NLP-inspired graph2vec algorithm to the weighted undirected setting, and employ it to obtain an embedding of the set of graphs. This embedding allows us to extract seven clusters of liquidity takers, with equivalent behavioural patters and interpretable trading preferences. We conclude our work by testing for relationships between the characteristic mechanisms of each pool, i.e. liquidity provision, consumption, and price variation. We introduce a related ideal crypto law, inspired from the ideal gas law of thermodynamics, and demonstrate that pools adhering to this law are healthier trading venues in terms of sensitivity of liquidity and agents’ activity. Regulators and practitioners could benefit from our model by developing related pool health monitoring tools.

Abstract
Groundwater is important for human survival and development, particularly in arid and semi-arid regions, such as western Jilin Province. This study aimed to evaluate the hydrochemical characteristics and nitrate human health risks of groundwater in the semi-arid plains of western Jilin Province, northwest China. The study collected of 88 and 151 phreatic and confined water samples, respectively, which were analyzed for 13 water quality indicators using statistical and graphical methods. The Combined Weighted Water Quality Index (CWQI) based on the entropy weight, Criteria Importance Though Inter-criteria Correlation (CRITIC), the coefficient of difference method, and the water quality index (WQI) was used to evaluate the water quality of the study area. The human health risk assessment (HHRA) model was used to assess the risks of nitrate to the health of humans among different age groups. The results indicate that: (1) Groundwater in the study area is weakly alkaline and the main hydrochemical types of the phreatic and confined water were HCO3−·Ca-Mg and HCO3−-Na. (2) Rock weathering was the dominant processes responsible for groundwater ions, whereas groundwater hydrochemistry was also affected by silicate weathering and cation exchange. (3) Although the quality of groundwater was generally good, 9.1% of phreatic water samples failed drinking water standards. (4) The areas in which groundwater nitrate posed a higher risk to human health are mainly in the saline-alkali lands of Qian'an, Tongyu, and Zhenlai, with 15.9% of water samples exceeded the nitrate standard for children. This study can improve the understanding of groundwater hydrochemical characteristics and human health risks in the study area and can contribute to the study of groundwater in semi-arid regions.

Abstract
Backgroud: There are approximately 100,000 proteins in humans with various physiological functions. The study of proteome in relation to calorie intake is expected to play an important role in solving major aging-associated problems in humans, such as obesity, diabetes, cardiovascular disease and cancer. Objective: To study the changes in serum proteins in young and old rats that were intermittently fasted. Method: 3 and 19 months old rats were intermittently fasted, Every 48 hours. The weights of both young and old rats were taken before feeding, while the young rats received 4g per 100g of body mass the adult rats received 1.75g per 100g of body mass for 14 days. Consecutively both young and old rats received a fattening ration of 25g feed ad lithium every 24 hours irrespective of age for 14 days. Throughout the experiment, animals were kept in individual cages with free access to water. Blood samples were collected after cervical dislocation. The blood serum was then analysed on SDS-PAGE electrophoresis. Results: Apolipoprotein A1 sharply increased in young rats during refeeding periods. Immunoglobulin light chains (lambda and kappa) levels increased during starvation in young rats. Apolipoprotein E levels in young animals was initially high during first cycle of starvation, Also In young animals alpha1-macroglobulin was observed to be high following starvation. In young animals apoA-4 increased during the first cycle of feeding. In young animals the levels of alpha1-antitrypsin flunctuated between the period of starvation and feeding, With higher levels been observed during starvation. In old rats after the first, Second intermittent fasting and second refeeding, Apo E, Apo A-4 and Apo A1 increased, While other serum proteins remained suppressed. Conclusion: The intermittent fasting in young and adult experimental animals, induced adaptive stress by upregulating and downregulating some serum proteins.
Combinatorial Generation of Planar Sets
Authors: Roussillon Tristan 
Published: January 2023

Abstract
We introduce a multi-dimensional generalization of the Euclidean algorithm and show how it is related to digital geometry and especially to the generation and recognition of digital planes. We show how to associate with the steps of the algorithm geometrical extensions of substitutions, i.e., rules that replace faces by unions of faces, to build finite sets called patterns. We examine several of their combinatorial, geometrical and topological properties. This work is a first step towards the incremental computation of patterns that locally fit a digital surface for the accurate approximation of tangent planes.

Published: January 2023

Abstract
Objectives: To report a resident-led otolaryngology clinic experience at an independent Federally Qualified Health Center (FQHC) with an affiliated academic center. We compared delivery of subspecialty care for underserved patients in a unique resident run clinic to standard care at the university staffed subspecialty clinics.
Methods: Retrospective cohort study of surgical patients seen at the Social Action Community Health System (SACHS) otolaryngology clinic over a one-year period compared with a matched control cohort of patients having similar procedures at the affiliated faculty academic practice. Measured endpoints were case type, time of referral to consultation, time interval between surgical decision and date of surgery, surgical complications, as well as post-surgical follow up.
Results: A total of 687 new patients were seen at SACHS clinic, with approximately 18% ultimately undergoing surgery. All otolaryngology sub-specialties were represented including otology, facial plastics, and head and neck oncology. SACHS patients had overall slightly higher median interval times from referral to consultation and from surgical decision to date of surgery though this did not reach significance. There were no differences in surgical outcomes or complication rates between the SACHS cohort and faculty cohort.
Conclusions: We demonstrate a mutually beneficial partnership between a fully resourced FQHC system and an otolaryngology residency program to provide reciprocally beneficial training experience and effective health care delivery.
Almost Universally Optimal Distributed Laplacian Solvers via Low-Congestion Shortcuts

Published: January 2023

Abstract
In this paper, we refine the (almost) existentially optimal distributed Laplacian solver of Forster, Goranci, Liu, Peng, Sun, and Ye (FOCS `21) into an (almost) universally optimal distributed Laplacian solver. Specifically, when the topology is known (i.e., the Supported-CONGEST model), we show that any Laplacian system on an n-node graph with shortcut quality SQ(G) can be solved after no(1) SQ(G) log(1/ε) rounds, where ε > 0 is the required accuracy. This almost matches our lower bound that guarantees that any correct algorithm on G requires Ώ (SQ(G)) rounds, even for a crude solution with ε ≤ 1/2. Several important implications hold in the unknown-topology (i.e., standard CONGEST) case: for excluded-minor graphs we get an almost universally optimal algorithm that terminates in D · no(1) log(1/ε) rounds, where D is the hop-diameter of the network; as well as no(1) log (1/ε)-round algorithms for the case of SQ(G) ≤ no(1), which holds for most networks of interest. Moreover, following a recent line of work in distributed algorithms, we consider a hybrid communication model which enhances CONGEST with limited global power in the form of the node-capacitated clique (NCC) model. In this model, we show the existence of a Laplacian solver with round complexity no(1) log(1/ε). The unifying thread of these results, and our main technical contribution, is the development of near-optimal algorithms for a novel ρ-congested generalization of the standard part-wise aggregation problem, which could be of independent interest.
