Authors: Winiarska Dominika Maria , Szymański Paweł , Osiejuk Tomasz Stanisław 
Published: June 2023

Abstract
Passive acoustic monitoring has proven to have many advantages for monitoring efforts and research activities. However, there are considerations to be taken into account regarding the placement of autonomous sound recorders. Detection ranges differ among species and in response to variable conditions such as weather or the location of vocalising animals. It is thus important to the success of a research project to understand, with a certain degree of confidence, the distances at which birds might be detected. In two types of forests in Poland, we played back the vocalisations of 31 species of European forest birds exemplifying different singing characteristics. Based on recordings obtained along a 500-m transect, we estimated the probability of detection and maximum detection distance of each vocalisation. We simulated three heights of singing and repeated playbacks three times during the breeding season to evaluate the effect of vegetation growth. Our results revealed that environmental and meteorological factors had a significant influence on both detection probability and maximum detection distances. This work provides comprehensive measurements of detection distance for 31 bird species and can be used to plan passive acoustic monitoring research in Europe, taking into account species traits and individual characteristics of the study area.

Abstract
Background: Onchocerciasis or river blindness is a parasitic endemicity caused by a filariasis called Onchocerca volvulus. This nematode worm is transmitted to humans due to bites by infested female black flies. In 2002, WHO closed the Onchocerciasis control programme in West Africa at the time when the disease transmission risk was constricted in all countries where Onchocerciasis was a cause of concern. The aim of this study is to evaluate Onchocerciasis transmission in the Kafolo area, located at the Ivorian-Burkinabe border in the region of Tchologo in Côte d’Ivoire, after the period of interruption of the national Onchocerciasis control programme activities, and following the observation of an increase in the disease prevalence in both sides of the border.
Methods: Standardized human landing catches of black flies based on a WHO/OCP technique were carried out in 2019 at the intervals of two (2) days per month. Caught black flies were dissected to look for potential onchocerca larvae. These larvae were then analyzed through the PCR technique 0 - 150 to identify their species.
Results: Annual Bitting Rates (ABR) were 25,355 and 20,235 bites/person/year at Kafolo-Amont and at Kafolo-Aval respectively, with an average parturity rate of 60.33% at the level of the first site and 55.23% at the level of second one. Adjusted infectivity rates amounted to 3.93 IF/1,000 pares and 4.91 IL/1,000 pares for Kafolo-Amont (Upstream) and to 4.03 IF/1,000 pares and 6.71 IL/1,000 pares for Kafolo- Aval (Downstream). Adjusted ABR reported 75 bites/person/year in each site. This rate exceeds almost 4 times the threshold defined by WHO for the disease control. the high transmission rate observed in this study was not expected and could constitute a potential source of contamination of adjacent river basins across the border in Burkina Faso.
Conclusion: There is active onchocerciasis transmission continues at Kafolo. Therefore, Onchocerciasis elimination is not yet achieved in this site. The subsequent recommendation is that entomological and epidemiological transmission prevalence data be updated in this area.
Failure Characteristics of Thick Hard Roof Stratum under Hydraulic Pre-splitting and Its Application in A Coal Mine, Dongsheng Mining Area
Authors: Zhu Jing-zhong , Li Wen-ping , Teng Bo , Liu Yu 
Published: June 2023

Abstract
Due to the presence of the hard suspended roof, it cannot collapse naturally after being mined in a large-scale goaf. If the roof suddenly destroys without human intervention, it would cause serious disasters. In this paper, we discuss the mechanisms and applications of hydraulic fracturing in alleviating the potential for catastrophic disasters. After the fracturing crack propagation principle, we investigate the failure and stress characteristics of overburden with and without fracturing, taking a mine in Dongsheng mining area. The results show that the regulated roof suffers severe damage after fracturing, and the initial rupture distance of hard roof is reduced to 40 m or so. Additionally, the development height of water-conducting fissure zone is approximately 138.18 m. The fracturing effect can be preliminarily speculated according to fluid pressure curves. It is inferred that hydraulic fracturing point 3 has the best damage effect on the hard suspended roof. On the other hand, a common trait of overburden stress is easily observed by monitoring points, namely that the overburden stress after fracturing shows a relatively smaller value. The study provides theoretical support for the safety management of thick hard roofs, especially in the coal mines seriously affected by roof accidents.

Abstract

Purpose
Gram-negative rod (GNR) bacteremia has been suggested as a clinical marker of occult cancer; however, no studies are available in this regard in the Japanese population. Here, we investigated the risk factors for gastrointestinal cancer with GNR bacteremia.
Methods
Patients with GNR bacteremia admitted to St. Luke’s International Hospital between January 2011 and July 2021 were included. The clinical data of patients with and without cancer, 1 year before and after GNR bacteremia diagnosis, were compared. Univariate analysis was performed using χ2 and Fisher’s exact tests for categorical variables and the Mann–Whitney U test for continuous variables, while multivariable analysis was performed using logistic regression analysis, and a p of < 0.05 was considered statistically significant.
Results
Of 2,296 GNR bacteremia-positive patients, 96 were associated with gastrointestinal cancer, and univariate analysis showed significant differences between the gastrointestinal cancer and comparison groups in terms of mean body mass index (20.2 vs. 21.8 kg/m2), Enterobacteriaceae detection (64.6% vs. 81.3%), and anaerobic GNR detection (24.0% vs. 8.5%). Thirty-five (36%) and 61 (64%) patients had upper and lower gastrointestinal cancer, respectively. There were 23 patients with anaerobic GNR bacteremia related to 24 strains, (upper and lower gastrointestinal cancer, 5 and 18 cases, respectively). Multivariate analysis identified anaerobic GNR (odds ratio 2.4, 95% confidence interval 1.2–4.6) as a significant risk factor for cancer.
Conclusions
Anaerobic GNR in blood cultures may be a risk factor for gastrointestinal cancer. Therefore, it is necessary consider cancer workup, such as endoscopy, for patients with anaerobic GNR bacteremia.
Three-dimensional stability lobe diagram construction in milling process with considering multiple modes

Published: June 2023

Abstract
In the milling process, chatter has a significant impact on tool abrasion, machining surface quality and productivity. Stability lobe diagram (SLD) is one of the earliest methods used for offline chatter prediction. Traditionally, a two-dimensional SLD constructed by only selecting the most flexible mode and can seek the limit of axial depth of cut at a corresponding spindle speed. However, the SLD constructed only with the most flexible mode is not accurate enough when two or more important flexible modes existed with nearly the same modal stiffness, moreover, when the whole number of full vibration cycles between passages of two teeth is relatively small the SLD will fail to predict in some certain spindle speed ranges. This paper develops a three-dimensional SLD of the spindle speed, axial and radial depth of cut with considering multiple modes to solve the inaccurate prediction problem mentioned above. In consideration of the fact that accurate calibration milling force coefficients is essential for construction of SLD, a calibration procedure is presented to obtain more accurate milling force coefficients based on the average force method. In addition, as the basic input parameters for establishing the SLD, four modal parameters are identified via impact test. Then, a two-dimensional SLD is established in frequency domain by using the zero-order approximation method (ZOA) with two important flexible modes existed with nearly the same modal stiffness. Finally, a three-dimensional SLD can be constructed by scanning at different radial depths of cut and taking the lowest envelop of the two modes SLD. The validity, accuracy and basic principles of the above method are verified by a series of experiments.

Published: June 2023

Abstract
School attendance problems is a broader symptomatology that includes “School Refusal” due to internalizing problems and “Truancy” linked to externalizing problems. These different profiles of young patients might highlight specific developmental trajectories and specific risk factor profiles. The aims of this study is to present retrospective data to compare school refusal to three different populations (Truancy, behavior disorder and Anorexia Nevrosa) of inpatients thought dimensional approach on development and environmental aspects. In this study, we highlight risk factors profile for school refusal and truancy. School refusal inpatients are characterized by associated specific risk factors usually found in internalizing problems: medical complications during pregnancy, learning disorder, isolation/reject and bullying in peer relationships. It is frequently associated with a diagnosis of anxiety and depression and suggest difficulties in emotional dysregulation and problems of socializing with peers. In behavior disorder and truancy groups, associated to externalizing problems, the following associated specific factors were found: unwanted pregnancy, substance abuse during pregnancy, baby sleeping disturbances, delayed language development, attachment disorder, learning disorder, physical abuse, violent and conflictual family relationships, breaking contact with parents and a concomitant diagnosis of conduct disorder or oppositional defiant disorder. The highlight of these two profiles should enable the identification of specific axes of intervention according to the type of problem, whether internalized or externalized.

Abstract

Background: Oral anticoagulant treatment represents one of the most important therapeutic advances of the last century as an indication of chronic anticoagulation par excellence for atrial fibrillation. Direct oral anticoagulants (DOACs) stand out for their predictable effect at a fixed dose, reduction of drug interactions, and ease of use, since they do not require monitoring, which allows greater flexibility in management than vitamin K antagonists.
Aim: Analyze the implementation of the management Protocol for direct-acting oral anticoagulants in primary health care.
Methods: A quasi-experimental study was designed to improve the management of DOACs in patients with atrial fibrillation. The study began in June 2017 and ended in December 2018. The DOAC management protocol was developed by the research team following the recommendations of scientific societies.
Results: Regarding the information received by the DOAC user, 15.4% did not know that they were taking an anticoagulant, 43.1% did not receive information about the DOAC at the time of prescription, and 21.5% received information written. Regarding the content of the information in primary health care, the information on the risk of bleeding was found in the upper part with 100%, followed by the importance of adherence with 90%. The follow-up need was met in 60%. 34.1% of patients with DOAC have a specific episode, 90.1% do not have any specific nursing follow-up visit, and the frequency of analytical controls is inadequate in 60.7% in patients older than 75 years. 62% with associated comorbidity and 75% with altered renal function.
Conclusions: As a conclusion of the ZAR-ACOD study, the management Protocol for direct-acting oral anticoagulants has been correctly implemented in our population with atrial fibrillation. We can highlight the improvement in the follow-up and control of patients undergoing anticoagulant treatment after the application of the protocol.
Optimizing cultivation and shipping environments for an edible green alga, Caulerpa chemnitzia var. laetevirens (Bryopsidales) from Japan: Effects of temperature, irradiance, desiccation, and salinity on photochemical efficiency
Authors: Terada Ryuta , Matsuda Koki , Nishihara Gregory N. 
Published: June 2023

Abstract
The effects of four stressors, temperature, irradiance, desiccation, and salinity, on the photochemical efficiency (ΔF/Fm') of a green alga, Caulerpa chemnitzia var. laetevirens from Kagoshima, Japan were determined for optimizing cultivation and shipping environments using a pulse amplitude modulation (PAM)-chlorophyll fluorometer. The ΔF/Fm' remained stable at 24–34°C during the 3-d temperature exposures ranging from 8–36°C; however, it dropped at higher and lower temperatures. During continuous 6-h exposure to irradiance levels of 400 (low), and 1000 (high) µmol photons m− 2 s− 1 at 16, 24, and 32°C, the decline of ΔF/Fm' was pronounced at high irradiance. Moreover, the ΔF/Fm' also dropped at 16°C even under low irradiance, suggesting the occurrence of low temperature–light stress. Desiccation experiments under 50% humidity and up to 5-h of aerial exposure at 24°C and dim-light (20 µmol photons m− 2 s− 1) indicated that ΔF/Fm' was well tolerated within 1-h of desiccation; however, it dropped quickly as the desiccation period prolonged, suggesting that if more than 20% of the thallus interior water was lost, ΔF/Fm' dropped progressively. However, during a similar experiment up to 14 days of aerial exposure under saturated humidity (99%) and dim-light (12L12D photoperiod), as the interior water of the thallus was maintained due to the saturated humidity, ΔF/Fm' seemed to be well maintained for up to 5 days. Like desiccation, this alga exhibited stenohaline characteristics (30–40 psu) under the salinity gradient of 0–80 psu up to 7 days of culture at 24°C and dim light (12L12D). In conclusion, this alga can be cultivated by modifying the techniques used for cultivating Japanese Caulerpa lentillifera and adjusting its environment accordingly. To ensure appropriate shipping conditions, it is essential to maintain saturated humidity in a plastic container at room temperature.
Standard Scaling and PCA-based Logistic Regression Model for Classifying and Detecting DDoS Attack
Authors: Gupta Avinash , Kumar Anoj 
Published: June 2023

Abstract
Distributed Denial of Service Attack (DDoS) is one of the attacks used by cybercriminals against the target system in the world of technology. Using this attack, attackers tried to fool the target system and force the targeted system to deny the request of genuine clients. As a result of a successful attack, the targeted system becomes unavailable from the Internet, and the client gets a message of service unavailability. To perform this attack, the attacker tries to create fake traffic by using different approaches. This fake traffic forces the targeted system to deny the request of further requests received by genuine clients. Here DDoS stands for “Denial of Service,” which means denying clients' requests. For securing the services from DDoS attacks, here we propose a machine learning model for detecting and classifying DDoS attacks. This will help us to safeguard the services from this type of attack. In this paper, we are going to propose two different machine learning models which will help us to classify and detect the DDoS attack performed on the system. For creating the first model, we used standard scaling to pre-process the data. For the second model, we apply Principal Component Analysis(PCA) over the standard scaling to reduce the features present in the dataset so that the complexity of the model can be reduced. After preprocessing the dataset, we apply Logistic Regression in the dataset and build two different models, which help us to classify and detect the DDoS Attack.
The Significance of Kappa and F-score in Clustering Ensemble: A Comprehensive Analysis
Authors: Yan Jie , Liu Xin , Qi Ji , You Tao , Zhang Zhong-Yuan 
Published: June 2023

Abstract

Clustering ensemble techniques have gained significant attention due to their ability to enhance partition results’ accuracy and robustness. Selective clustering ensemble (SCE) and weighted clustering ensemble (WCE) methods further improve performance by selecting and weighting base partitions or clusters based on their diversity and stability. However, striking a balance between these two factors remains challenging. The primary difficulty lies in evaluating the quality of base partitions and clusters. Existing evaluation criteria, such as normalized mutual information (NMI) and its variants, suffer from inherent flaws, including symmetric problem, context meaning problem, and the disregard for small clusters’ importance. To address these limitations, this paper proposes a novel evaluation method that utilizes kappa and F-score. We introduce a new SCE method that employs kappa to select informative base partitions and utilizes F-score to assign weights to clusters based on their stability. Empirical validation on real datasets demonstrates the effectiveness and efficiency of the proposed approach.

Authors: Atoloye Kehinde Adebola , Lawal Temitayo Victor , Adebowale Ayo Stephen , Fagbamigbe Adeniyi Francis 
Published: June 2023

Abstract
Background
Pneumonia remains a public health challenge in most parts of the world, with Nigeria having the highest number of pneumonia-related deaths. Understanding the geographical distribution, trends and risk factors associated with some symptoms of pneumonia can aid an appropriate preventive intervention towards abating its burden in Nigeria.
Method
This cross-sectional study used data from the 2008, 2013, and 2018 Nigeria Demographic Health Surveys. The outcome variables include fever, cough, and short, rapid breaths as selected symptoms of pneumonia. Optimized hotspot analysis was used to identify areas with a significantly high prevalence of fever, cough, and short rapid breaths, and a MCMC random-intercept logistic regression model was fitted to each symptom.
Results
The prevalence of cough was 12.1%, 10.1% and 16.9% in 2008, 2013 and 2018 respectively, 16.2%, 13.3%, and 25.7% for fever; and 41.7%, 42.5% and 6.5% for short rapid breaths respectively with variations across the states. Children aged 6-11 months had the highest higher odds (adjusted odds ratio (aOR) =1.95, 95% Credible Interval (CrI): 1.77, 2.18) of having cough, compared to children of other age groups. Similar pattern wasss noticed for fever and short rapid breaths. Other significantly associated factors with symptoms include the mother’s education, mother’s age, residence type, housing quality, wealth index and region.
Conclusion
The northern states were more characterized by short, rapid breaths while the southern states were more characterized by fever but both regions have a fair share of cough among under-five children. For cough and fever symptoms, the increased prevalence between 2013 and 2018 indicates more attention is needed. There is also higher odds of finding the symptoms amongst children aged 6-11 months compared to children of other age groups, especially in the North-eastern part of the country. Hence, government needs to strengthen immunization against diseases such as Hib, pneumococcus, measles and whooping cough (pertussis) which has been shown to be the most effective way to prevent pneumonia. Adequate nutrition is also key to improving children's natural defences. Educated mothers needs to be adequately sensitized to understand that exclusive breastfeeding for the first 6 months of life of a child is paramount.
Scheelite composition fingerprints pulsed flow of magmatic fluid in the Fujiashan W skarn deposit, eastern China

Published: June 2023

Abstract
Scheelite (CaWO4) is an economically important W mineral in skarns that form when magmatic fluids exsolved from a granitic intrusion react with carbonate wall rocks. In the Fujiashan W skarn deposit, scheelite formed during four stages of the hydrothermal skarn development. We present cathodoluminescence (CL) images and in situ trace element and Sr-O isotope data of scheelite from these four stages, i.e., scheelite in prograde and retrograde skarn, quartz-sulfide veins, and late calcite replacements. Scheelite from prograde skarn and quartz sulfide veins are homogeneous and show oscillatory zoning textures in CL images, whereas scheelite from retrograde skarn and late carbonate stages display dissolution-reprecipitation and patchy textures. The brightness of CL textures decreases with a higher substitution of Mo. Molybdenum-rich scheelite (up to 2.1 wt%) is characterized by relatively high contents of Nb and Ta (up to 156 and 0.9 ppm, respectively), positive Eu anomalies, high-δ18O values (5.2 to 5.9‰), and relatively low-87Sr/86Sr values (0.70661 to 0.70727), and has grown in a system with a continuous supply of magmatic fluid. Molybdenum-poor scheelite (0.2 wt%) has low contents of Nb and Ta, negative Eu anomalies, low-δ18O values (4.2 to 4.3‰), and relatively high-87Sr/86Sr ratios (0.70748 to 0.70804). This type of scheelite formed in a system with a restricted flow of magmatic fluid during scheelite precipitation became increasingly depleted in elements that substitute into scheelite. The continued reaction of the magmatic fluid with the wall rocks and the precipitation of minerals from the fluid resulted in a systematic change of the δ18O and 87Sr/86Sr ratios. Chemical and isotopic variations in scheelite may reflect the pulsed flow of a magmatic fluid and do not require the involvement of different fluids or contrasting redox conditions.
