Abstract
Non-operative treatment is the mainstay of colonic diverticulitis, but some patients require surgery due to non-operative treatment failure. This study aims to identify risk factors for the failure of non-operative treatment of colonic diverticulitis. From January 2011 to December 2020, we retrospectively reviewed 2362 patients with non-operative treatment for first-attack acute diverticulitis. Patients were categorized into non-operative treatment success or failure groups. Clinical characteristics and serum inflammatory markers were analyzed by multivariable logistic regression to determine risk factors for non-operative treatment failure of colonic diverticulitis. Overall, 2.2% (n = 50) of patients underwent delayed surgery within 30 days (median 4.0 [3.0; 8.0]) due to non-operative treatment failure. Multivariable logistic regression identified that platelet to lymphocyte ratio (odds ratio [OR], 4.2; 95% confidence interval [CI], 0.05–0.13; p < 0.001), diabetes mellitus (OR, 2.2; 95% CI, 0.01–0.09; p = 0.025), left-sided colonic diverticulitis (OR, 4.1; 95% CI, 0.04–0.13; p < 0.001), and modified Hinchey classification (OR, 6.2; 95% CI, 0.09–0.17; p < 0.001) were risk factors for non-operative treatment failure. Platelet to lymphocyte ratio (PLR) is a potential risk factor for the non-operative treatment failure of acute first-attack colonic diverticulitis. Therefore, patients with higher PLR during non-operative treatment should be monitored with special caution.
Adpative multivarite RLV reentry attitude control with pre-specified performance in the presence of unmatched disturbances

Published: January 2023

Abstract
This paper presents a new adaptive multivariable attitude control method for the reusable launch vehicle (RLV) to track desired attitude trajectories subject to unknown external disturbances and uncertainties. In contrast to most designs neglecting mismatched disturbances, this method employs an adaptive finite-time observer (AFO) to estimate the unknown states. Based on the outputs from the AFO and the prescribed performance function, a time-varying non-overestimated adaptive gain is designed to construct the adaptive multivariable attitude control for the RLV system. Simulation studies were carried out and the results show that the proposed approach is able to steer the RLV to track desired attitude signals in the presence of unmatched disturbances and uncertainties.

Abstract
Purpose To describe three patterns of posterior plane edge identification in small-incision lenticule extraction to prevent lenticule mis-dissection.
Methods Femtosecond laser application was performed for small-incision lenticule extraction (SMILE) by one surgeon. The surgical videos of SMILE were recorded and re-watched by the surgeon after operation.
Results Small-incision lenticule extraction was performed in 52 eyes of 28 patients, and no patient had cap-lenticular adhesion. Three patterns of posterior plane of lenticule were noticed when the surgical videos were re-watched. A "double line" attached to the dissector was visible, signifying the reflective tape of the edge of the lenticule and the cap. During the expansion of the posterior lamellar separation, a fusiform opening between the lenticule edge and the underlying matrix layer was assumed to be a "leaf sign". With some unintentional operation, the posterior lamella was pushed away from the surgeon. The edge of the lenticule away from the anatomical part, the marking of the femtosecond laser cut, and the edge of the cap layer showed three reflective bands, which formed a "triple line".The "double line", "leaf sign" and "triple line" were observed in 30 eyes (57.7%), 21 eyes (40.4%) and 1 eye (1.9%), respectively.
Conclusion Thesethree signs cover possible situations and provide visual landmarks to identify the correct dissection of the posterior plane, which can help shortenthe learning curve of novice doctors.
Incentives for promoting climate change adaptation technologies in agriculture: An evolutionary game approach
Authors: Sun Yong , YU RUIHUI , Cheng Tai Chiu Edwin 
Published: January 2023

Abstract
Climate change adaptation technologies (CCATs) have become an important tool for farmers to cope with climate change and address the risks of natural disasters, but in many rural areas, there is still a reliance on traditional agricultural techniques. It is necessary to explore the incentives for promoting CCATs in agriculture, and the conditions for the effectiveness and realization of policy measures. In this paper, we construct an evolutionary game model to analyze the behaviour of local governments and farmers in promoting CCATs. Our findings are as follows: Under certain conditions, the evolutionary game of promoting CCATs in agriculture can achieve equilibrium. Within a certain range, the incentive for farmers to choose to adopt CCATs increases with local governments’ risk subsidy and cost-sharing. When the subsidy is too high, local governments may choose the no- promotion strategy, under which the policy incentive disappears, reducing the incentive for farmers to adopt CCATs. Publicity is an important incentive for promoting CCATs, and its effect is evident. Our findings provide insights into the development of policies to promote CCATs in agriculture.

Published: January 2023

Abstract
Many studies have dealt with the effect of invasive species in urban environments, leading to decline in species richness, and changes in the composition of faunal communities. However, few studies have investigated the role of native species while turning into invasive pests. In Colombia, Atta cephalotes, a native leaf-cutting ant (LCA), has responded successfully to the conversion of natural ecosystems to agricultural-rural environments and, most recently, to residential and urban development. In this case study, we illustrate the response of this native ant species to urban disturbs in the physical environment, resource availability, and ecosystem processes associated with human urbanization in Cali, the third most important city in Colombia. Atta cephalotes nests were present in all green areas sampled and, even in human dwellings, the ants harvested both native and introduced plant species. Despite being well adapted to intensively modified urban environments, this ant species appears to be dependent on human-subsidized resources. As discussed in the light of published studies, ecological competence, resource availability, opportunistic behaviour, reduction of natural enemies and heat islands can be identified as key factors driving the urban proliferation of this LCA species. Given the wide distribution of leaf-cutting ants, it is, plausible to expect that similar processes are underway in other Latin American countries where these ants are found. Hence, this study also proposes to alert the academic and social communities to direct future research towards evaluating both the responses and impacts of these ants in relation to changes in the urban landscape.

Published: January 2023

Abstract
Discrete chaotic synchronization is crucial in secure communication. Studies on the design of a discrete chaotic system mainly depend on the system. Some discrete chaotic systems cannot synchronize as required. In this study, we proposed a new algorithm blended with error control for designing an inverse discrete chaotic synchronization system. Based on the eigenvalues of the synchronization error system, the coefficient matrix of the discrete chaotic system was inversely controlled for precisely controlling the positive Lyapunov exponents in the system. The results indicated that the error control-blended inverse discrete chaotic synchronization system had good chaotic characteristics and high reliability and flexibility.
Compact description of quantum phase slip junctions
Authors: Koliofoti Christina , Riwar Roman-Pascal 
Published: January 2023

Abstract
Quantum circuit theory is a powerful and ever-evolving tool to predict the dynamics of superconducting circuits. In its language, quantum phase slips (QPSs) are famously considered to be the exact dual to the Josephson effect. However, this duality renders the integration of QPS junctions into a unified theoretical framework very difficult, and as we show, gives rise to serious inconsistencies for different formalisms, and in some cases difficulties to include time-dependent flux driving. We propose to resolve these issues by reducing and compactifying the Hilbert space describing the QPS processes. Our treatment provides for the first time a unified description of the Aharonov-Bohm and Aharonov-Casher effects, properly defines the valid form of inductive interactions to an environment, and allows to account for recent insights on how to include electromotive forces. Finally, we show that the compactification is likewise important for correctly predicting the available computational space for qubit architectures involving QPS junctions.

Abstract
Cancer-associated adipocytes (CAAs), one of the primary stromal components, exhibit intimate crosstalk and release multiple cell factors mediating local and systemic biological effects. However, the role of CAAs in the regulation of systemic immune responses and their potential value in the clinical treatment of triple-negative breast cancer (TNBC) are not well described. Transcriptome sequencing was performed on CAA and normal adipocyte (NA) tissues isolated from surgically resected samples from TNBC patients and healthy controls. Cytokines, including C-X-C motif chemokine ligand 8 (CXCL8, also known as IL-8), secreted from NAs and CAAs were compared by transcriptome sequencing and enzyme-linked immunosorbent assay (ELISA). Proliferation, migration and invasion assays were employed to analyze the role of CAAs and CAA-derived CXCL8 (macrophage inflammatory protein-2 (MIP2) as a functional surrogate in mice). TNBC syngraft models were established to evaluate the curative effect of targeting CXCL8 in combination with anti-PD-1 therapies. Real-time quantitative polymerase chain reaction (RT-qPCR), western blotting (WB), polymerase chain reaction (PCR) array, flow cytometry, immunohistochemistry (IHC), and immunofluorescence (IF) were applied to analyze immune cell infiltration and epithelial-mesenchymal transition (EMT) markers. Specifically, we demonstrated that CAAs and CAA-derived CXCL8 played important roles in tumor growth, EMT, metastasis and tumor immunity suppression. CAA-derived CXCL8 remodeled the tumor immune microenvironment not only by suppressing CD4+ T and CD8+ T immune cell infiltration but also by upregulating PD-L1 expression in TNBC. The combination of targeting CXCL8 pathway and blocking PD-1 pathway synergistically increased the tumor immune response and inhibited tumor progression. Thus, our results highlight the molecular mechanisms and translational significance of CAAs in tumor progression and immune ecosystem regulatory effects and provide a better understanding of the potential clinical benefit of targeting CAA-derived CXCL8 in antitumor immunity and as a new therapeutic moiety in TNBC.
A data-driven method for the correction of optical distortions of depth cameras in immersion NDT&amp;E

Published: January 2023

Abstract
Stereoscopic cameras (a class of depth cameras) are increasingly present in robotics navigation and 3D scene reconstruction. Normally, off-the-shelf depth cameras are not suited for underwater environments and exhibit considerable distortions in the provided 3D images when operating underwater. This is mainly due to the large difference in the refractive coefficients of air and water. This issue prevents their use in subsea applications such as the inspection of oil pipelines, valves and manifolds, where these devices could be used for odometry during ultrasonic inspections as well as for 3D scanning. Aiming to allow for such applications, we present a data-driven method for the correction of distortions caused by unaccounted diffractions in depth cameras. First, the distortion is modelled via a series of detections of control points from a standard target at known underwater positions, and an approximation of the inverse distortion is obtained. Then, at runtime, a procedure takes as input the (distorted) point cloud given by the camera at each frame, applies the inverse distortion, and yields a corrected point cloud. We apply the method to data provided by a RealSense D405 camera encased in a sealed acrylic container underwater. The correction made it possible to use the camera for 3D imaging underwater with root mean square error (RMSE) below 10 mm in the worst case tested. The method clears the path for the use of off-the-shelf depth cameras in a wide range of subsea applications.

Published: January 2023

Abstract
In order to preliminarily explore the distribution of antibiotic pollution in the coastal waters of eastern China, the concentrations of 13 antibiotics in 5 representative coastal rivers in Jiangsu and 21 sampling sites in the coastal waters of Jiangsu were analyzed. The total antibiotic concentrations in the 5 rivers ranged from 33.14 ng L-1 to 417.78 ng L-1, and the total antibiotic concentrations in the 21 sampling sites ranged from 0.90 ng L-1 to 86.33 ng L-1. The concentrations of antibiotics in a sampling site decreased as the distance of the sampling site from the coastline increased, indicating that river inputs are important sources of antibiotic pollution in the coastal waters of Jiangsu. The detection rates of roxithromycin, lincomycin, azithromycin, and sulfamethoxazole in the rivers and sampling sites were above 70%. Correlation analysis showed that the concentrations of antibiotics were positively correlated with the levels of total phosphorus and chemical oxygen demand. An ecological risk assessment revealed that roxithromycin posed a moderate risk to aquatic organisms in the coastal waters of Jiangsu. The results of this study highlight the significance of monitoring and controlling the concentrations of antibiotic contaminants in the coastal waters of Jiangsu.

Published: January 2023

Abstract
The article presents hyperchaos image encryption using DNA (deoxyribonucleic acid) coding and the chaotic maps in discrete cosine transform. The proposed multilayered security system comprises of advanced levels of confusion and diffusion. Initially, the diffusion among the pixels is attained by employing DNA XOR operation between pixel values and the unpredictable sequence generated from hyperchaotic system. Secondly, the pixels of the partially encrypted image is scrambled by Baker map to permute the image pixels. Finally, the partially encrypted image is diffused through the discrete cosine transform. The significant contribution of this algorithm is to improve the quality of encryption through a DNA encoded scheme. The demonstration results and experimental values are in support the robustness of the proposed scheme and have shown resistance against underlying cryptanalytic attacks.

Published: January 2023

Abstract
A series of fibrous aminated adsorbents for CO2 adsorption were prepared by covalent incorporation of poly (glycidyl methacrylate) (PGMA) by graft copolymerization of GMA onto electron beam (EB) irradiated polyethylene/polypropylene (PE/PP) fibrous sheets and subsequent amination with ethylenediamine (EDA), diethylenetriamine (DETA) or tetraethylenepentamine (TEPA). The physico-chemical properties of the adsorbents were evaluated using Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), X-ray diffraction (XRD), thermogravimetric (TGA) and Brunauer-Emmett-Teller (BET) analysis. Of all adsorbents, TEPA-containing fibres showed the highest CO2 adsorption capacity and thus was further investigated for CO2 capture from CO2/CH4 mixtures of different gas ratios under various pressures and temperatures. The selectivity of CO2 over CH4 and equilibrium isotherms, kinetics, and thermodynamics of the adsorption on the fibrous aminated adsorbent were all investigated. The Sips model was found to best fit the isotherm of CO2 adsorption suggesting the presence of a combination of monolayer and multilayer adsorptions. The adsorption kinetic data was found to best fit Elovich model reflecting chemisorption. The ΔG°, ΔS°, and ΔH° showed positive values suggesting that the adsorption of CO2 on the present fibrous adsorbent was non-spontaneous with an increase in randomness implying that the process was endothermic. Overall, it can be suggested that PE/PP-g-PGMA/TEPA adsorbent has a strong potential for separation of CO2 from NG.

Published: January 2023

Abstract
A hash table is a basic data structure for searching and retrieving data quickly. It's an important part of Artificial Intelligence (AI)/Machine Learning (ML) applications and advanced graph analytics. An effective hash function can make hashing effective. Existing hash table implementations either simplify the underlying model by supporting only a subset of hash table operations or use optimizations that result in highly data-dependent performance and, at worst, comparable to a sequential implementation of the problem. A dynamic hash table that supports all hash table queries—search, insert, delete, and update—while also allowing us to provide p parallel queries (p > 1) per clock cycle using p processing engines (PEs) in the worst-case, i.e., data agnostic performance. Our design is scalable up to 128PEs and supports throughput of up to 8000 Million Operations per Second (MOPS) at 325 MHz using state-of-the-art FPGAs. It supports the same set of operations as the hash table and achieves speeds up to 42.1× speedup. Using RXOR-based parallel hash tables, we achieve high throughput, low latency, and low power consumption.

Abstract
Banana is an important staple fruit crop consumed worldwide. The present study was carried out to evaluate the agronomic traits of 22 Musa cultivars of Assam, India, performed in a randomized complete block design with three replicates. The cultivars were evaluated based on different agronomic traits such as vegetative characteristics like pseudostem height/girth, pseudostem cross-sectional area, leaf length/girth, leave numbers, and peduncle length/girth. In addition, agronomic traits such as bunch height/girth, bunch weight, number of hands, numbers of fruits per bunch, finger length/girth, and finger weight were also evaluated. The yield of bananas varied from cultivar to cultivar depending on the agronomic traits. The highest yield was observed in Bhim (dangor) (38.34 t/ha) followed by Bharat moni (30.88 t/ha) and Jahaji (saru) (28.75 t/ha), whereas the lowest was recorded in Bawali manohar (11.47 t/ha) and Amrit sagar (11 t/ha). The Pearson's correlation among agronomic traits indicates that the bunch weight, bunch girth, number of hands, fruits per bunch, finger girth, and finger weight were significantly correlated with yield. On the other hand, the number of leaves was negatively correlated with yield. Overall, this study highlighted the agronomic traits of cultivated Musa genotypes, which would be helpful in the banana breeding program.

Abstract
Peanut is a world-renowned oilseed and food crop. Improving its biochemical quality traits is of great significance not only for meeting edible oil and food needs, but also for producing clean renewable energy. Identification of peanut genotypes with high and stable oil content in coastal areas is of economic importance, as the high oil trait of peanut bred in inland areas are difficult to fully express in coastal areas. Two peanut genotypes were grown at two sites in the coastal area. One of the genotypes was identified as with high oil and low carbohydrate, while the other, low oil and high carbohydrate. We noticed that number and total area of oil bodies were higher in high oil peanut than in low oil peanut, and that peanut with higher protein content had larger total protein body area. A novel finding of the present study was that number and area of starch grains were higher in peanut with high total soluble sugar (TSS) and sucrose contents than in peanut with low TSS and sucrose. Regarding the ultrastructural properties associated with oil, protein and TSS/sucrose contents, significant and highly positive correlations were detected between total oil body area and number of oil bodies, between total protein area and maximum protein body area, and between total starch grain area and number of starch grains. This study laid the foundation for further exploration of the mechanisms shaping peanut seed biochemical quality through transcriptomic, metabolomic and hormonal analysis.
