Abstract
Purpose
Lower gastrointestinal bleeding (LGIB) can be fatal; therefore, several scoring systems have been developed to predict its prognosis. We aimed to compare the mortality predictions and evaluate the usefulness of various scoring systems.
Methods
The medical records of 3,794 patients who visited the emergency department with hematochezia between January 2016 and December 2021 were retrospectively reviewed. We calculated the areas under the receiver operating characteristic curves (AUROCs) for 30-day mortality and prolonged hospital stay (≥ 10 days), based on the age, blood tests, and comorbidities (ABC); AIMS65; Glasgow Blatchford; Oakland; Rockall (pre-endoscopy); and SHA2PE scores. We compared the predictive accuracy of each score.
Results
Data for 963 patients (median age, 69 years; males, 54.5%; median hospital stay, 6 days) with colonoscopy-confirmed LGIB were analyzed. The 30-day mortality rate was 3.5%. The most common causes of LGIB were ischemic colitis and diverticulum hemorrhage in 19.3% and 19.2% of the cases, respectively. The AIMS65 (AUROC, 0.845) and ABC (AUROC, 0.835) scores were superior in predicting 30-day mortality (both p < 0.001). The SHA2PE score was the most accurate predictor of prolonged hospital stay (AUROC, 0.728; p < 0.001). Through multivariate regression analysis, 30-day mortality was correlated with albumin level ≤ 3.0 g/dL, international normalized ratio > 1.5, blood urea nitrogen level ≥ 30 mg/dL, and systolic blood pressure (SBP) < 100 mmHg. Prolonged hospital stay was correlated with liver cirrhosis, hemoglobin ≤ 10 g/dL, albumin level ≤ 3.0 g/dL, and SBP < 100 mmHg.
Conclusion
The recently developed scoring systems accurately predict LGIB prognosis, and their usefulness in clinical decision-making was confirmed.

Published: January 2023

Abstract
Thermal conductivity measurements of ten refrigerant mixtures (R-404A, R-406A, R-407C, R-409A, R-410A, R-415A, R-507A, R-227ea/R-134a 61.5/38.5, R-227ea/R-134a 88.8/11.2, R-227ea/R-134a 45/55) in the gas phase are analysed. The thermal conductivity was studied with the same experimental setup, which improved the reliability of the results, excluding thereby systematic errors caused by using different methods to measure thermal conductivity. The reported experimental data have 1.5–2.5 % uncertainty. Equations for calculating thermal conductivity depending on temperature and pressure are given for each mixture. The equations for thermal conductivity on the dew line and in the ideal gas state are obtained. A model for predicting thermal conductivity on a wide range of state parameters is proposed based on obtained experimental data and the theory of thermodynamic similarity. A comparison of the experimental data with the calculation model gives the standard deviation at 0.4–2.1 %, which does not exceed the measurement error.
Stabilizing the Propagation of the Weighted Finite-Difference LSRTM Riemannian Wavefield Extrapolator
Authors: Muhammed Hussein 
Published: January 2023

Abstract
Earth’s subsurface illuminating is a great problem of interest. Least-squares reverse-time migration is considered as a cutting-edge technique due to its advance structural irradiating which can be seen from the corresponding mathematics and optimization. Its procedure consumes a lot of time and occupies huge memory amounts thus wavefield extrapolation has been juxtaposed in a Riemannian coordinate system to transform the vertical axis to overcome the above-mentioned issues and oversampling/aliasing for modelling deeper parts of the seismic section. The problem of stabilizing this Riemannian wavefield arises from the introduction of the mapping velocity and the vertical axis operator that converts the finite difference solution partially from time into frequency domains. For every point in the Cartesian space, there is a corresponding vertical-time point with the coordinates hence we can interpolate the reconstructed source wavefield by drawing a Cartesian-to-Riemannian mapping function. Our stability and convergence analysis suggests that the spatial derivatives of Riemannian axis can be approximated by a Fourier pseudo-spectral methods as well as fast-Fourier transform using a special Gaussian-like impulse function to generate the vector-matrix of the source term within the finite-difference operator, in addition to the mapping velocity, which is a differential form of the initial input velocity model, manifestly controls the CFL conditions of the associated Riemannian-finite difference operator. Numerical and synthetic examples indicate that this approach is more stable and efficient in extrapolating a smooth Riemannian wavefield while maintaining Claerbout’s principle for locating subsurface reflectors also choosing an appropriate sampling rate for the new vertical axis is related inversely by the maximum frequency of the impulse wavelet and directly with minimum velocity value in the given model.

Abstract

We propose an innovative framework for assessing the probability that a subject drawing is the work of a particular artist. While numerous efforts have applied neural networks to classify two-dimensional works of art by style and author, these efforts — with few exceptions — have been limited to paintings. Drawings, which can involve multiple media with very different visual characteristics and greater susceptibility to damage than paint, present a more formidable challenge. Our technique is robust to the age and wear of a drawing as well as the possibility that it contains marks made with multiple drawing media. We obtained classification accuracies exceeding 90% using a five-layer convolutional neural network (CNN), which we trained on a curated set of drawing images attributed to Raffaello Sanzio da Urbino (1483–1520), known as Raphael, as well as drawings by his admirers, imitators, and forgers.

Published: January 2023

Abstract
The red imported fire ant (RIFA), Solenopsis Invicta Buren (Hymenoptera: Formicidae), is an invasive species that is considered to be among the 100 most dangerous species to human health and the environment. RIFA is currently controlled primarily by chemical pesticides. Human health concerns and environmental problems require environmentally friendly, green control technology. In this study, the HS-SPME–GC/MS method was used to determine the volatile components of six essential oils, namely I. verum, B. balsamifera, C. lemon, A. tatarinowii, M. chinensis and C. cassia, as well as the fumigation activity of RIFA. There was an identification of D-Limonene as a core volatile. Except for C. limon essential oil, all other five plant essential oils exhibit excellent fumigation activity under the treatment of a high dose (10 µL) within 24 h. All plant essential oils are capable of causing the death of all red fire ants, while C. limon essential oil exhibits the lowest fumigation activity at 63.25%. Significant reductions in RIFA aggregation, aggressiveness, and gripping abilities were observed with all plant essential oils, and antenna sensilla appeared to bend or break. Moreover, after treating red ant fire ants with essential oil for 24 h, three protective enzymes were assessed. All six plant essential oils were shown to have enhanced enzyme activities for superoxide dismutase (SOD), glutathione S-transferase (GST), and catalase (CAT). It has been shown that plant essential oils have the capability of reducing the viability of red fire ants via physiological, receptor, and behavioral factors, ultimately causing them to die off. In this study, plant oils were demonstrated to be negatively affecting RIFA and providing a green and environmentally sustainable control method.
Three-non Quantum Communication
Authors: Xu Qifeng 
Published: January 2023

AbstractIn the 40 years since the BB84 protocol was proposed, the practical progress of quantum communication has been relatively slow, because many key technologies have not yet made breakthroughs. This paper proposes a model that can be supported by existing technologies, that is, three-non quantum communication which has no quantum key distribution, no teleportation, and no information transmission. Its working principle is that Alice uses fiber channel or free space to send polarized entangled photon streams to Bob and has the controllable decoherence of entangled photons with the industrial-grade optoelectronic devices, and her control role is equivalent to information coding to realize communication functions. It also has other characteristics such as no requirement for code rate, single-photon detection, quantum base operations and classical channel, etc. It has a low requirement for light sources and transmission channels and is easy to implement.

Authors: Zhang Song , Zhang Song , Ma Zhaolei 
Published: January 2023

Abstract
Objective
To compare the prognostic effects of two different anesthesia methods on endovascular treatment (EVT) of acute anterior circulation ischemic stroke.
Methods
We collected 90 cases of patients with acute anterior circulation ischemic stroke who received endovascular treatment, and these patients were randomly divided into general anesthesia (GA) group and conscious sedation (CS) group before operation. We recorded the related parameters of EVT under the two anesthesia methods for comparative study. The main outcome index of this study was a good neurological prognosis after 90 days of EVT.
Results
In this study, a total of 174 patients with acute ischemic stroke were screened, 90 cases met the inclusion criteria. The 90 cases were randomly divided into GA group and CS group before receiving EVT. Of the 90 cases, 88 cases achieved different degrees of vascular recanalization, and all cases were followed up. There was no significant difference in baseline data, mortality, vascular recanalization, incidence of pneumonia, hospitalization time in ICU, postoperative intracranial hemorrhage, improvement of MRS and NIHSS scores between patients in the two groups. Arterial dissection occurred in 6 cases in CS group and 1 case in GA group, with significant difference. The mean arterial pressure at 10, 20, 30, 60min after anesthesia were different. The time of arterial puncture was different in the two groups, but there was no difference in the time of vascular recanalization. There was no significant difference in neurological function prognosis between patients in the two groups at 90 days. However, there are differences in terms of lung infection, mortality and ICU hospitalization time of elderly patients between the two groups.
Conclusion
There was no significant difference in neurological prognosis between the two anesthesia methods for 90 days after endovascular treatment of acute anterior circulation ischemic stroke. Conscious sedation was superior to general anesthesia for elderly patients.

The olive (Olea europaea L.) is one of the most important plants grown in many Mediterranean countries that has a high economic value. Olives, which are specific to each region, have different bioactive components. In this study, we investigated the phenolic/flavonoid contents, as well as antioxidant, antimicrobial, and antithrombotic activities of the fruit, leaf, and seed extracts obtained from the Halhalı olive grown in Arsuz district of Hatay, Turkey.
Antioxidant activities of the phenolic compounds found in the olive fruit, seed, and leaf extracts were determined by employing established in vitro systems. Total phenolics were determined as gallic acid equivalents, while total flavonoids were determined as quercetin equivalents. Also, we evaluated a possible interaction between oleuropein and aggregation-related glycoproteins of the platelet surface via docking studies.
The extracts showed effective antioxidant activity. The seed extract had the highest phenolic content of 317.24 μg GAE, while the fruit extract had the highest flavonoid content of 4.43 μg. The highest potential for metal chelating activity was found in the leaf extract, with an IC50 value of 13.33 mg/mL. Also, the leaf extract showed higher levels of antioxidant, antithrombotic, and antimicrobial activity, compared to the fruit and seed extracts. The docking scores of oleuropein against the target molecules GPVI, α2β1, and GPIbα were calculated as –3.798, –4.315, and –6.464 kcal/mol, respectively.
The olive fruit, leaf, and seed extracts used as experimental material in our study have remarkable antioxidant, antimicrobial, and antithrombotic potential.

Published: January 2023

Kashk is a perishable fermented dairy product. Since chemical preservatives are harmful for human health, we aimed to study lemongrass (Cymbopogon citratus L.) as a natural preservative.
First, we assessed the phytochemical properties of lemongrass extract. Then, we added lemongrass extract and microencapsulated lemongrass extract to kashk samples. Finally, we analyzed their physicochemical and sensorial properties during 60 days of storage.
Catechin (419.04 ± 0.07 mg/L), gallic acid (319.67 ± 0.03 mg/L), and chloregenic acid (4.190 ± 0.002 mg/L) were found to be the predominant phenolic constituents in lemongrass. Total phenolics, total flavonoids, and antioxidant activity (IC50) values of the lemongrass extract were 26.73 mg GA/g, 8.06 mg Quercetin/g, and 2751.331 mg/L, respectively. The beads were spherical in shape with a 35.03-nm average particle diameter and 47.81% microencapsulation efficiency. The pH of the supplemented kashks decreased during the storage time. They showed lower acid degree values than the control at the end of storage. The peroxide, p-anisidine, and thiobarbituric acid values of the sample fortified with microencapsulated lemongrass extract were 6.15, 4.76, and 44.12%, respectively, being the lowest among the samples. This kashk sample had the highest hardness (570.62 ± 21.87 g), adhesiveness (18.10 ± 4.36 mJ), and cohesiveness (0.56 ± 0.25) but the lowest chewiness (72.66 ± 3.08 mJ) among the samples. It also had a better sensory profile than the control samples.
Our results indicated that microencapsulated lemongrass extract could be incorporated into kashk to ensure suitable sensorial and textural properties. Furthermore, it may delay fat oxidation and lipolysis during storage.

Published: January 2023

Background
The construction of an elimination stoma has a physical, psychological, and social impact on the person. The development of stoma self-care competence contributes to the adaptation to a new health condition and improvement of quality of life. eHealth refers to everything associated with information and communication technology and health care, including telemedicine, mobile health, and health informatics. The use of eHealth platforms by the person with an ostomy, as a digital application that includes websites and mobile phone apps, can bring scientific knowledge and well-informed practices to individuals, families, and communities. It also allows functionalities that enable the person to describe and identify early signs and symptoms and precursors of complications and to be guided to an adequate health response for their problems.

Objective
This study aimed to define the most relevant content and features to promote ostomy self-care integrated into an eHealth platform as a digital app or website to be used by patients for self-management of stoma care.

Methods
We developed a descriptive, exploratory study with a qualitative approach using the focus group methodology, which was oriented to reach a consensus of at least 80%. A convenience sample of 7 participants consisting of stomatherapy nurses was used. The focus group discussion was recorded, and field notes were taken. The focus group meeting was fully transcribed, and a qualitative analysis was performed. The research question was: Which content and features for ostomy self-care promotion should be integrated into an eHealth platform as a digital app or website?

Results
An eHealth platform, which can be a smartphone app or website, for people with ostomy should provide content aimed at promoting self-care, namely in the field of knowledge and self-monitoring, as well as the possibility of interacting with a stomatherapy care nurse.

Conclusions
The stomatherapy nurse has a decisive role in promoting adaptation to life with a stoma, namely through the promotion of stoma self-care. Technological evolution has emerged as a useful tool to enhance nursing interventions and promote self-care competence. The development of an eHealth platform aimed at promoting ostomy self-care should include the capabilities for telehealth and help with decision-making regarding self-monitoring and seeking differentiated care.
