Evaluation of Apically Extruded Debris during Root Canal Filling Material Removal in Teeth with External Apical Root Resorption: A Comparison of Different Obturation Techniques
Authors: Çağlar Büşra Melike , uzun ismail
Published: November 2023

Aim
Root canal retreatment is required when the initial procedure fails. While NiTi systems aid in filling material removal, some preparation methods can extrude canal contents, leading to inflammation, pain, and delayed healing due to the design and kinematics of endodontic files. This study seeks to mitigate complications and promote healing by limiting the dispersion of materials to periradicular tissues. It also investigates the impact of preparation techniques and endodontic file systems on apical debris volume to identify the optimal method for minimizing extrusion during filling removal.
Material and Method:
Ninety extracted maxillary incisor teeth were studied. Simulated apical root resorption was created by removing the apical 2 mm of the root with a fissure bur. The teeth were divided into two groups: one filled with a single cone and the other with cold lateral compaction. These were further split into three subgroups (n = 15 each). Subgroup 1 used Reciproc R25 for removal and R50 for final preparation. Subgroup 2 employed PTUR files D1, D2, D3 for removal and ProTaper Next X5 for finalization. Subgroup 3 utilized VDW.RotateR for removal and VDW.Rotate 50.04 for completion. Debris from retreatment was collected in pre-weighed eppendorf tubes to determine the amount. The apical extrusion data underwent a two-way analysis of variance.
Results
The Reciproc group had a mean weight of extruded debris of 0.54 ± 0.24 mg, significantly higher than the PTUR (0.28 ± 0.15 mg) and VDW.RotateR (0.39 ± 0.29 mg) groups (p < 0.05). The single-cone technique (SCT) resulted in a mean debris weight of 0.34 ± 0.23 mg, statistically lower than the cold lateral compaction (CLC) technique, which had a mean of 0.46 ± 0.27 mg (p < 0.05). While there was no significant difference in retreatment time between file systems (p > 0.05), the SCT group had a mean retreatment duration of 111.12 ± 33.46 seconds, shorter than the CLC group's 176.26 ± 52.26 seconds (p < 0.05).
Conclusion
The Reciproc file system and the CLC obturation technique resulted in greater apical debris extrusion than other methods. Although retreatment time remained consistent across file systems, the SCT had a quicker duration than the CLC method. The Reciproc groups are more susceptible to extrusion from the apex during retreatment.
Clinical Relevance:
This study is crucial for dental practitioners, offering insights into minimizing complications during root canal retreatment, enhancing patient outcomes by guiding the selection of optimal techniques and file systems.

Published: November 2023

Climate change is a vital driver of biodiversity patterns and species distributions, understanding how organisms respond to climate change will shed light on the conservation of endangered species. In this study, the MaxEnt model was used to predict the potential suitable area of 12 threatened medicinal plants in the QTP (Qinghai-Tibet Plateau) under the current and future (2050s, 2070s) three climate scenarios (RCP2.6, RCP4.5, RCP8.5). The results showed that the climatically suitable habitats for the threatened medicinal plants were primarily found in the eastern, southeast, southern and some part of the central regions on the QTP. Moreover, 25% of the threatened medicinal plants would have reduced suitable habitat areas within the next 30-50 years in the different future global warming scenario. Among these medicinal plants, FP (Fritillaria przewalskii) would miss the most habitat (97.1%), while the RAN (Rhododendron anthopogonoides) would miss the least habitat (0.30%). Nevertheless, 41.6% of the threatened medicinal plants showed an increase in their future habitat area because of their physiological characteristics which are more adaptable to a wide range of climate. The climatic suitable habitat for 50% of the threatened medicinal plants would migrate to higher altitudes or higher latitudes regions.
This study provides a data foundation for the conservation of biodiversity and wild medicinal plants on the QTP.

Published: November 2023

Objectives
This study aimed to compare apical debris extrusion and canal preparation time of two NiTi files (ProTaper-Gold (PTG), ProTaper-Ultimate (PTU)) when operated with irrigation solutions of different temperatures.
Materials and Methods
Mesio-buccal roots of sixty mandibular first molars were distributed into six groups depending on the file type (PTG, PTU) and irrigation solution temperature (20°C, 37°C, 45°C). During canal preparation, apically extruded debris was collected in glass tubes, where the difference of the pre and post extruded debris wight was measured. The time required for canal preparation was recorded in seconds. One-way and two-way ANOVA tests were used followed by multiple comparisons using the Bonferroni post-hoc test.
Results
Both file systems were associated with debris extrusion, which was affected by the file type and temperature (p < 0.05). Only PTU was affected by the temperature with significantly lower extrusion at 37°C. The canal preparation time was only affected by the temperature, (p = 0.001) without a significant effect of the file type (p = 0.552). Both file types had shorter canal preparation times at 20°C.
Conclusions
The novel PTU file system has a similar performance to the PTG at room and body temperatures and higher debris extrusion on heated irrigation, the irrigant temperature could influence the debris extrusion and time of preparation.
Clinical relevance:
This study highlights the importance of considering the temperature of irrigation solutions during root canal treatment. Depending on the file system used, the temperature was found to impact the amount of apical debris extrusion and canal preparation time during instrumentation.

Pig farming is a significant economic activity, especially in the Southern states of Brazil. However, it can have environmental impacts, primarily through the discharge of liquid effluents into the soil. Therefore, this study aimed to analyze the variability in the concentration of chemical elements in the soil in two areas located on the same property, one using swine waste and the other without, in the Northwestern region of the Rio Grande do Sul State. To do this, the concentrations of the chemical elements Cadmium, Chromium, Cobalt, Copper, and Zinc were analyzed at three depths (0.00, 0.50, and 1.00 meters) using Flame Atomic Absorption Spectrometry. Physical parameters (particle size distribution and saturated hydraulic conductivity) were also determined. The results indicated that the soil has low permeability, with a predominance of the silt fraction. Regarding the chemical parameter analyses, values above the levels established by current legislation were identified, with Copper and Cadmium showing higher values at all analyzed spots and depths. Significant differences between the areas were observed only at a depth of 1.00 meter and for the elements Zinc, Cobalt, and Manganese. It can be concluded from this that the use of swine liquid waste did not alter the natural properties of the soil, and the higher concentration of Copper may be related to the geological origin of the region. For some chemical elements, leaching through the soil profile and/or translocation of the clay fraction to deeper layers were observed.

Published: November 2023

Primary open angle glaucoma (POAG) is a chronic, progressive optic neuropathy with a characteristic optic disc and no other eye disease or congenital abnormality. We have collected a 4-generation family of POAG from Chinese Han nationality. Gene-chip linkage localization and whole exome sequencing were performed on this family to identify pathogenic mutations. Linkage localization analysis identified a linkage peak overlapping with glaucoma candidate genes on chromosome 2, with a LOD value of 2.4, a NPL value of 4.62. Whole exome sequencing revealed frameshift variant in GTF2A1L gene on chromosome 2, which was adjacent to linkage localization. The specific frameshift mutation of GTF2A1L gene correlates with the phenotype of glaucoma in this family, which conforms to an autosomal dominant inheritance pattern.
Enhancing Insight into Regional Differences: Hierarchical Linear Models in Multiregional Clinical Trials
Authors: Kim Jeewuan , Kang Seungho
Published: November 2023

Background: The planning and analysis of multi-regional clinical trials (MRCTs) has increased in the pharmaceutical industry to facilitate global research and development. The ICH E17 guideline emphasizes the importance of considering the potential for regional differences, which may arise from shared intrinsic and extrinsic factors among patients within the same region in MRCTs. These differences remain as challenges in the design and analysis of MRCTs.
Methods: We introduce and investigate hierarchical linear models (HLMs) that account for regional differences by incorporating known factors as covariates and unknown factors as random effects. Extending previous studies, our HLMs incorporate random effects in both the intercept and slope, enhancing the model's flexibility. We facilitate understanding through illustrative figures that depict the distribution of the primary endpoint and covariates under the proposed models. Moreover, we investigate the test statistics for the overall treatment effect and derive the required sample size under the HLM, considering both a fixed number of regions and real-world budgetary constraints.
Results: Our simulation studies show that HLMs with random effects in both the intercept and slope provide empirical type I error rates that are closer to the nominal level than those of conventional models. However, the estimate for the regional variabilities remains challenging for the small number of the regions. Budgetary constraints impact the required number of regions, while the required number of patients per region is influenced by the variability of treatment effects across regions.
Conclusion: We offer a comprehensive framework for understanding and addressing regional differences in the primary endpoint for MRCTs. Through the proposed HLMs and required sample size, considering the budget constraints, designs for MRCT could be more efficient.
Ten-year follow-up after chemotherapy (S1 + cisplatin + trastuzumab) and surgery for human epidermal growth factor receptor 2-positive stage IV esophagogastric junction cancer with pathological complete response: a case report
Authors: Enomoto Takeharu , Mikami Shinya , Otsubo Takehito , Tsuda Takashi , Chosokabe Motohiro
Published: November 2023

Background:
In recent years, many reports have focused on the usefulness of conversion surgery, in which chemotherapy is given to patients with unresectable advanced gastric cancer (GC) and radical surgery is performed if resection becomes possible. However, no consensus has been reached regarding the usefulness of this strategy.
Case presentation:
A 74-year-old man was diagnosed with GC after experiencing abdominal pain. Esophagogastroduodenoscopy revealed an elevated lesion with ulceration at the esophagogastric junction (40 mm in size, type 1 gross type), and biopsy revealed well-differentiated adenocarcinoma. Chest and abdominal computed tomography showed wall thickening at the hilum and multiple enlarged lymph nodes in the left supraclavicular fossa and around the aorta from the hilum to the upper abdomen. These findings were consistent with a malignant tumor at the esophagogastric junction, and esophagogastric junction cancer was diagnosed [T3N3M1 (LYM): stage IV]. Chemotherapy was chosen, and seven courses of S1 + cisplatin (SP) + trastuzumab (HCN) were administered. The patient developed neuropathy, and two courses of S1 + HCN were administered. Approximately 10 months after the start of chemotherapy, upper gastrointestinal endoscopy and positron emission tomography/computed tomography showed that the tumor was almost gone; therefore, we decided to perform conversion surgery. The patient underwent open total gastrectomy, D2 lymph node dissection, and Roux-en-Y reconstruction. Scarring at the esophageal junction was evident on palpation of the specimen, but pathologic examination of the specimen and dissected lymph nodes showed no cancer. Postoperatively, the patient underwent 2 cycles of S1 + HCN followed by 48 cycles of HCN until the second postoperative year. No metastasis or recurrence was observed for 9 years after surgery.
Conclusions:
We have reported a case of stage IV esophagogastric junction cancer with a pathological complete response obtained by SP + HCN therapy. Conversion surgery after chemotherapy resulted in recurrence-free survival. However, further study is needed to elucidate the effect of surgery on top of chemotherapy for stage IV GC as chemotherapy continues to evolve.
Screening of Multi-Traits PGPR isolates for their potential as Growth Promoters for Wheat plantation
Authors: Mathur Abhishek , Jain Rashmi , Singh Devendra
Published: November 2023

Background
Global food production has increased by historic amounts thanks to the Green Revolution of the 20th century. Chemical inputs (pesticides, herbicides, and chemical fertilisers) and better crop plants (achieved through selective breeding and sophisticated genetic engineering) made up the bulk of the Green Revolution. Gains from fertilizer inputs, however, come at a significant environmental cost. To meet the needs for food, fuel, and fiber of a growing global population and a changing environment during the 21st century, a new agricultural innovation revolution will be required. It is necessary for a "Fresh" Green Revolution—possibly the Bio-Revolution—to be built on fewer intensive inputs with less negative environmental impact. Some of the bacteria have evolved into facultative intracellular endophytes as a result of the co-evolution of plants and microbes. PGPR is one of these bacteria that may live freely and has both direct and indirect advantages for plants. In order to increase plant tolerance to biotic and abiotic stress, beneficial rhizobacteria have been used. The mechanism(s) through which soil bacteria display beneficial activities are frequently unclear, despite the fact that, several soil bacteria have been found to support plant growth and development.
Results
The PGPRs viz. RS03 Bacillus subtilis, RS07 Bacillus cereus, RS21 Bacillus mycoides and RS25 Pseudomonas fluorescens were isolated and screened independently and also in possible combinations for evaluation of growth promotion activities in wheat (Triticum aestivum). The growth promotion activity was determined after 50 days of treatment in terms of growth parameters like plant height, shoot dry mass and root dry mass, seedling length and vigor index. Effect of PGPR isolates [sole as well as consortium] shown enhanced effect on germination %, growth and vigor index of wheat plants in comparison to non-inoculated control plants. The consortium application of RS03 + RS07 + RS21 + RS25 showed maximum seedling vigor index followed by the RS03 + RS21 + RS25.
Conclusions
Effect of PGPR isolates [sole as well as consortium] shown enhanced effect on germination %, growth and vigor index of wheat plants in comparison to non-inoculated control plants. The consortium application of RS03 + RS07 + RS21 + RS25 showed maximum seedling vigor index followed by the RS03 + RS21 + RS25.

Published: November 2023

Introduction:
Ventricular septal defects (VSDs) account for 50% of congenital heart defects (CHDs) in children. Moderate to large VSDs can lead to heart failure. To prevent future complications, surgical closure of moderate to large VSDs using patch material is considered the standard treatment in children within the first year of life.
Objectives:
We evaluated the fate of VSD patch leak and its impact on aortic and tricuspid valve regurgitation at 1 year after surgery.
Methods:
Patients with a perimembranous VSD who underwent surgery between January 2016 and December 2021 were included in the study. Demographic, echocardiographic, clinical and operative data were retrospectively reviewed. All patients’ echocardiographic images were analyzed at discharge and 3, 6, and 12 months after surgery. Echocardiography assessment focused on the degree of residual VSD (rVSD) patch leak and aortic and tricuspid regurgitation grade compared with preoperative echocardiography.
Results:
Seventy-one consecutive patients who underwent perimembranous VSD surgical closure were included. There was no mortality during follow-up. No patient required re-intervention. Forty-three patients (~ 61%) had no rVSD patch leak on discharge. On 12-month follow-up echocardiography, 67 patients (95.7%) had no rVSD patch leak. Aortic and tricuspid valve regurgitation significantly improved from discharge to 12 months after surgery. No relationship between the size of the patch leak and patient weight was identified (P value = > 0.005).
Conclusions:
We demonstrated that a less than 2 mm rVSD patch leak is benign in nature, has no impact on tricuspid or aortic valve function, and almost always decreases in severity or disappears.

Background
Moral distress occurs when people’s moral integrity is compromised by external factors. Healthcare workers experience difficult situations that can increase their moral distress.
Aim
To translate and validate the “Moral Distress Thermometer” (MDT) in Greek.
Methods
Our study included 142 nurses in Greece. We collected our data during September 2023. We employed the forward-backward method to translate and adapt the MDT in Greek. We examined the concurrent validity of the MDT using the “Moral Injury Symptom Scale-Healthcare Professionals” (MISS-HP), the revised “Rushton Moral Resilience Scale” (RMRS), the “Quiet Quitting Scale” (QQS), and the single item burnout measure. Moreover, we performed a test-retest study to examine the reliability of the MDT.
Results
The MDT showed very good psychometric properties. Concurrent validity of the Greek version of the MDT was exceptional. We found statistically significant correlations between the MDT and MISS-HP (r = 0.51, p < 0.001), RMRS (r = -0.33, p < 0.001), QQS (r = 0.41, p < 0.001), and the single item burnout measure (r = 0.40, p < 0.001). We found that the MDT had excellent reliability since the intraclass correlation coefficient in test-rest reliability analysis was 0.994 (95% confidence interval = 0.991 to 0.996, p-value < 0.001).
Conclusions
The “Moral Distress Thermometer” is a reliable and valid tool to measure moral distress among healthcare workers.

Authors: Karthikeyan V. , Palin Visu Y. , Raja E.
Published: November 2023

In India, water demands have risen inexorably over the last decade. The world's growing need for water has become a huge concern. The resource has been depleted due to wastewater, global warming, and industrialization. The importance of resource conservation and management must be prioritized. This work introduces an Internet of Things concept for water scanning and management in this work, which provides real-time feature extraction via the Internet. The suggested strategy addresses emerging needs within the aquatic sector, like gauging flow velocity and the imperative for scrutinizing water provision to minimize wastage and promote conservation. It also utilizes pH and conductivity sensors to examine the excellence of the aquatic that is distributed to every home. Traditional water metering methods necessitate consistent personal engagement for conservation, rendering them unwieldy and inefficient. To address the shortcomings of existing models, the proposed strategy employs wireless technology for smart quality sensing and information communication.

Published: November 2023

Several areas experience frequent floods due to anthropogenic activities. Among them, is the Dar es Salaam city, which experiences frequent floods along the Msimbazi River, whose flows originate from different tributaries including the Kinyerezi River. This study aims to evaluate the hydrological-sensitive areas of the Kinyerezi River sub-catchments using topographic index values (λ*) that enable the identification of areas with a higher probability of generating surface runoff. A digital elevation model was utilized to delineate the Kinyerezi River sub-catchment characteristics using ArcGIS 10.4. Soil infiltration rates (Ks) on selected open places were determined using a Guelph permeameter. Soil particle size distributions were analyzed and the λ* values were evaluated. The results showed the particle size distribution contains sand and silt-clay ranging from 46 to 84% and 16 to 53%, respectively. The Ks ranged from 0.6 to 7.8 mm/h while the sub-catchment KS3 scored the highest λ* value of about 10.7. Hence, there is a higher probability for generating surface runoff. Sub-catchment KS16 scored the smallest λ* value of 5.7, perceived to generate less surface runoff. Low-impact development practices capable of capturing runoff and enabling infiltration, evaporation, and detention should be employed in sub-catchments with higher λ* values.

Authors: Guo Yong , Cai Jindian , Liang Yaodong , He Yongjun
Published: November 2023

To solve the problem of liquid–liquid extraction of La(III), the oil-in-water Pickering emulsions were prepared by utilizing the aqueous solution of sodium alginate as the continuous phase, kerosene-diluted extractant di-(2-ethylhexyl) phosphate (P204) as the dispersed phase, and modified silica as an emulsifier. Then the emulsions were added to a calcium chloride solution to prepare the Pickering emulsion hydrogels (PEHGs) to better remove La(III). The PEHGs were characterized using Fourier transform infrared, thermogravimetric analysis, and scanning electron microscopy. The adsorption properties of PEHGs for La(III) in the aqueous solution were investigated using a UV–vis spectrophotometer. The study found that P204 was successfully coated by hydrogels and reached the highest adsorption capacity of 48 mg/g at pH 4. The amount of adsorption increased with the rise in temperature from 298 to 318 K. La(III) adsorption experimental data were more consistent with the pseudo-second-order kinetic model and the Langmuir isotherm model. Thermodynamic parameters showed that the adsorption of La(III) by PEHGs was a spontaneous endothermic process. The internal diffusion model revealed a linear relationship, indicating that internal diffusion played a role in the adsorption process. The encapsulating property of PEHGs indicated its potential usefulness in industrial wastewater for treating La(III).

Mitigating the negative impacts of abiotic stress is an important approach,
especially if climate change scenarios are realized. It is important to develop modern
applications to deliver adequate and safe food for human consumption, particularly in
arid and semi-arid regions that suffer from environmental and economic stressors. The
progress made by scientific research in the field of plant tolerance to stress conditions
during the last decade is considerable, but it needs to supply technical support for the
application. The development strategy is based on combining more than one technique
to achieve the integrated management of plants under different abiotic stresses, as will

Salt Stress and its Mitigation Strategies for Enhancing Agricultural Production
Authors: Saha Priyanka , Singh Bohra Jitendra , Barman Anamika , Bera Anurag
Published: November 2023

In agriculture, salinity has been a major limiting factor in food security. Soil
salinity has been shown to limit land utilization and crop productivity. It is especially
crucial to avoid such losses as the ever-increasing global population imposes a
tremendous amount of pressure on human populations to produce more food and feed.
Salt stress has a negative effect on the whole plant and can be seen at all phases of
growth, including germination, seedling and vegetative stages. Tolerance to salt stress,
on the other hand, varies with plant developmental processes and even from species
and cultivars. Salinity in the agricultural system can be managed by adopting various
mitigation strategies. To maintain higher productivity in salt-affected environments,
salt-tolerant genotypes must be introduced, as well as precise site-specific production
systems. Recent advances in genetics and biotechnology, along with traditional
breeding methods, provide the potential to create transgenic cultivars that perform well
under stress. Exogenous treatment of certain osmoprotectants and growth regulators, as
well as nutrient management and seed rejuvenation strategies, may be beneficial for
cost-effective agricultural production in saline soils

Published: November 2023

Social media, one of which is Instagram, has been proven effective as a hospital marketing medium. A private hospital in Tulungagung Regency has had an Instagram account for four months but has not been well managed. As a result, the account does not function optimally and reflect digital marketing facilities. Based on this condition, the researchers aimed to analyze the ways to optimize Instagram as a hospital digital marketing tool. The method used was experimental research with pre- and post-experimental design without control in a private hospital in Tulungagung Regency in October 2021. The unit analyzed was the hospital marketing department. Two interventions were implemented, providing digital marketing training through Instagram and optimizing the hospital's Instagram management. The knowledge instrument was measured using a questionnaire, and the Instagram management instrument was measured by examining Instagram Insights. The results showed that Instagram training and management could optimize the use of Instagram as a hospital digital marketing tool. Knowledge about Instagram and activity increased after training and management on Instagram had been implemented. Yearly, monthly, and daily schedule preparation needs to be implemented to increase marketing optimization. The absence of a dedicated settle team in charge of managing the Instagram account makes the implementation challenging to evaluate. A team specifically addressing hospital social media will be able to focus the work and improve the management, so digital marketing through social media can be optimized.

Published: November 2023

Non-Covid-19 service closure has formed a stigma that hospitals only serve Covid-19 patients. This condition affects brand awareness and decreases the number of hospital visits. An interactive talk show using Instagram can be used to reintroduce hospital services to the public. This study aimed to measure the success of the talk show program in building brand awareness of Udayana University Hospital's Instagram account. One group pretest-posttest research was carried out at Udayana University Hospital on October 7, 14, and 21, 2021, by intervening with the Instagram content of Udayana University Hospital. After the live broadcast ended, the talk show content was published on the Instagram feed. The success of the talk show program was seen by comparing the audience growth, engagement rate, and brand awareness measurements before and after the talk show took place. Brand awareness can be seen in profiles, post-impressions, and profile visits to the Instagram account. The highest post-engagement (36.46%) was obtained in the first episode of the talk show and was in the very high category. Instagram followers and engagement rates increased and categorized very high. Profile impressions and visit profiles increased, indicating a wide range of content on the Udayana University Hospital's Instagram account. This study shows that talk show program can be implemented as a routine program that builds brand awareness on the Instagram account of Udayana University Hospital. This program can be used as a solution to introduce Udayana University Hospital to Instagram users by inviting quality guest stars and using easy-to-understand material.

Published: November 2023

Treatment options for end stage lung diseases are limited to stabilizing lung failure, decreasing disease progression, and symptom management, but significant reversal of lost lung function is often not possible. For well selected patients, lung transplantation may be a viable option to improve both longevity and quality of life. Though outcomes for lung transplant recipients have improved over several decades, long term survival still lags behind that of other solid organ transplant recipients. Longevity after lung transplantation is limited by chronic lung allograft dysfunction. Numerous insults to the allograft contribute to chronic rejection, alloimmune injuries including acute T-cell mediated and antibody mediated rejection are chief among them. Therefore, monitoring for and management of acute cellular and antibody mediated rejection are of paramount importance to those caring for lung transplant recipients. We provide an up to date and comprehensive review of acute rejection affecting lung allografts and attempt to highlight pathophysiology, risk factors, clinical presentation, rejection phenotypes, management strategies, as well as related from of acute allograft injury.

Abstract: The face is one of the easiest ways to distinguish the individual identity of each other. Face recognition is a personal identification system that uses personal characteristics of a person to identify the person's identity. Human face recognition procedure basically consists of two phases, namely face detection, where this process takes place very rapidly in humans, except under conditions where the object is located at a short distance away, the next is the introduction, which recognize a face as individuals. Stage is then replicated and developed as a model for facial image recognition (face recognition) is one of the muchstudied biometrics technology and developed by experts. There are two kinds of methods that are currently popular in developed face recognition pattern namely, Eigenface method and Fisher face method. Facial image recognition Eigenface method is based on the reduction of face dimensional space using Principal Component Analysis (PCA) for facial features. The main purpose of the use of PCA on face recognition using Eigen faces was formed (face space) by finding the eigenvector corresponding to the largest eigenvalue of the face image. The area of this project face detection system with face recognition is Image processing. The software requirements for this project is MATLAB software.

Published: November 2023

Abstract: Convolutional neural networks (CNNs) have yielded state-of-theart performance in image classification and other computer vision tasks. Their application in fire detection systems will substantially improve detection accuracy, which will eventually minimize fire disasters and reduce the ecological and social ramifications. However, the major concern with CNNbased fire detection systems is their implementation in realworld surveillance networks, due to their high memory and computational requirements for inference. In this paper, we propose an original, energy-friendly, and computationally efficient CNN architecture, inspired by the SqueezeNet architecture for fire detection, localization, and semantic understanding of the scene of the fire. It uses smaller convolutional kernels and contains no dense, fully connected layers, which helps keep the computational requirements to a minimum. Despite its low computational needs, the experimental results demonstrate that our proposed solution achieves accuracies that are comparable to other, more complex models, mainly due to its increased depth. Moreover, this papershows how a tradeoff can be reached between fire detection accuracy and efficiency, by considering the specific characteristics of the problem of interest and the
Exploring the Different Types of Loads in Structures
Authors: Patel Rutvij
Published: November 2023

Abstract: Structural engineering relies heavily on loading. It is imperative that structural engineers or their relevant peers possess knowledge of the various loading types and their effects on structural elements. The structure cannot be constructed if the loading notion is not understood. Building a structure is impossible without comprehending this step. For instance, the analysis might not be correct and the building might collapse if there is no wind load conduction in a high-rise structure. This document covers the idea of loading, different types of loading, and how they affect structural parts.
Mapping forest plantations of the Volgograd region according to remote sensing data using the BSFI and NDWI indices
Authors: Vasilchenko A.A. , Vypritsky A.A.
Published: November 2023

The possibilities of adjusting the results of mapping wood plantations based on the bi-seasonal forest index (BSFI) according to Sentinel-2 data and calculated seasonal composite images of the NDWI index maximum values are presented. It was found out that with using a seasonal composite image of the mentioned values, calculated with the NIR and SWIR2 ranges, the manufacturer`s accuracy in raster cross-validation increases from 82,5 to 92,8 %. At the same time, the initial areas of wood zones decreased by 7 %, and those of false identifications shrank by 67 %. Comparison of mapping results with statistical data showed small differences in areas with a large number of natural forest plantations (in 18 of 33 areas they do not exceed 15 % of the design ones). Moreover, in lands with a large number of protective green spaces, discrepancies can reach up to 210 % of the design values. It is shown that significant distinctions in design and actual mapping materials can be associated with poor preservation, fires, illegal logging, as well as problems of accounting protective forest plantings. A fairly accurate method for adjusting BSFI was proposed (the manufacturer’s accuracy increased from 82,5 to 92,8 %) based on the maximum composite NDWI image calculated using the NIR and SWIR2 bands of the Sentilel-2A and Sentilel-2B satellites in a test area within the Volgograd region

Published: November 2023

Sentiment analysis plays an essential role in identifying user
preferences for recommender system. However, existing recommendation
systems mainly focus on the relationships between items and the user’s
purchasing behavior while ignoring the user’s sentiment information. To
improve the accuracy of recommender system, in this paper, a
multi-feature fusion recommendation model based on sentiment analysis
(MFF-SA) is proposed. Firstly, rather than sentiment values, sentiment
vectors are obtained by a new quantify sentiment method that based on
natural language processing, which to gain more valuable insights about
uses’ preferences. Secondly, to explicitly model the features
interactions, a multi-head self-attention mechanism is introduced, which
can capture multiple different aspects of the feature relationship
simultaneously. Finally, experimental results on three datasets
demonstrate that the proposed methods outperform the state-of-the-art
methods in terms of effectiveness and feasibility with a 3.9% relative
improvement.
