Biomedical event extraction using pre-trained SciBERT
Authors: Mulya Dimmas , Khodra Masayu Leylia 
Published: January 2024

AbstractBiomedical event extraction is applied to biomedical texts to obtain a list of events within the biomedical domain. The best GENIA biomedical event extraction research uses sequence labeling techniques with a joint approach, softmax decoder for event trigger identification, and the BioBERT v1.1 encoder. However, this event extraction model has three drawbacks: tasks are carried out independently, it does not provide special handling of multi-label event trigger labels, and it uses an encoder with vocabulary from non-biomedical domains. We propose to use the pipeline approach to provide forward information sigmoid to address multi-label event trigger labels and alternative BERT encoders with vocabulary from the biomedical domain. The experiment showed that the performance of the biomedical event extraction model increased after changing the encoder, which had been built using a biomedical-specific domain vocabulary. Changing the encoder to SciBERT while still using the joint approach and softmax decoder increased the precision by 4.22 points (reaching 69.88) and resulted in anF1-score of 58.48.

Authors: Chang Wanjun , Zhu Mingdong 
Published: January 2024

Abstract
This study proposes an emotional analysis method of consumer comment text based on Bidirectional Encoder Representations from Transformers (BERT) and hierarchical attention. First, using the BERT pre-training model, the left and right contextual information is fused to enhance the semantic representation of words and generate dynamic word vectors containing contextual semantics. Second, the bidirectional long short-term memory network is used to obtain the sequence feature matrix, and the sentence representation and the text representation are obtained using the two-layer long short-term memory. Finally, the local attention mechanism and the global attention mechanism are introduced into the sentence representation layer and the text representation layer, respectively, and the text emotion of consumer comments is classified by softmax. Experiments show that the accuracy of the proposed method in Laptop data set is 93.01% and that in Restaurant data set is 92.45%. Therefore, the performance of the proposed method in the emotional analysis of consumer comment text is significantly better than that of the comparison method.

Published: January 2024

Abstract
We report on the analysis of individual dye loaded block copolymer (BCP) vesicles via a combination of confocal laser scanning microscopy (CSLM)/fluorescence lifetime imaging microscopy (FLIM) on the one hand and atomic force microscopy (AFM) on the other hand. AFM measurements on ATTO 647N-loaded poly(styrene-block-poly(acrylic acid)) (PS115-b-PAA15) vesicles were carried out with high spatial resolution and afforded morphology and dimensions of BCP vesicles on solid substrates. By contrast the CSLM and FLIM data are diffraction limited, but from the time resolved fluorescence data information on the local vicinity of the reporter dye can be extracted. In the combined experiment individual dye-loaded vesicles and vesicle aggregates were discerned, analyzed metrologically by AFM and in more detail by CSLM and FLIM. On the basis of FLIM data the partitioning of the reporter dye was analyzed. The dye resides preferentially in the hydrophilic corona inside the vesicles. The dye concentration in the polymersome was about 90 times higher than in the solution used for encapsulation. These results underline that the combination of AFM with sensitive optical techniques, especially FLIM, is a promising approach for obtaining a deeper understanding of molecular interactions and nanoenvironments in supramolecular macromolecular structures and beyond.
Harmonic current suppression method of virtual DC motor based on fuzzy sliding mode
Authors: Shang Lisha , Jia Yajuan , Zheng Liming , Xie Gaoshang 
Published: January 2024

Abstract
In the operation of power grid, the low frequency subharmonics in power lines are easy to cause harmonic current problems. A harmonic current suppression method is constructed based on fuzzy sliding mode and virtual DC motor (VDC). First, the adaptive linear network is introduced to compare and analyze the output value and the actual value in the power line, and the possible harmonic current is obtained, which is detected and discretized. After that, this study adopts Fuzzy sliding mode control (FSMC) strategy for VDC, uses FSMC to participate in on-off control of VDC, and then realizes the suppression of harmonic current in VDC ports. In addition, the model also uses the circuit superposition theorem and the amount of harmonic data to be compensated by FSMC. The whole method uses VDC control technology to ensure the voltage stability of DC bus and load side when the load changes. In this physical experiment, harmonic current generated by load disturbance is eliminated by reducing DC harmonic voltage, so as to achieve the suppression of DC port harmonic current. Experimental results show that the third and fifth harmonics in power lines can be eliminated by this method to a large extent. Therefore, the proposed method can accurately detect and eliminate the harmonic current caused by sudden load change, and then realize the suppression of VDC harmonic current.

Abstract
The world today presents significant environmental concerns for humans, such as smog and warmer temperatures, but we also need to think about how to accomplish economic growth that is sustainable. Therefore, this exploration researches the asymmetric effect of renewable energy consumption, economic growth and financial development on carbon emanation in the emerging economies. For this reason, this investigation uses Panel ARDL and PMG estimator. The consequences of PMG estimator demonstrate that information and communication technologies reduce the carbon emanations in the sample region. Additionally, renewable energy consumption also impedes the carbon emanations. The results also suggest that financial development additionally builds the carbon emissions but the impact is very minor. Finally, economic growth and population are also contributing toward carbon emissions. The power effective recommendation is vital to present the ICT assistance to confine the utilization of obsolete machinery for power generation.

Published: January 2024

Nutritional status based on BMI is not only influenced by biological factors but also affected by demographic, economic, socio-cultural and environmental conditions of a population.The present paper intends to study the nutritional status with reference to age and family income among the Bengali Muslim and Meitei Women of Cachar District, Assam.The data have been collected by household census method and nutritional anthropometry among 172 Bengali Muslim and 181 Meitei women of 20 to 64 years age.The study reveals that 40.1% of Bengali Muslim and 30.4% of Meitei women are suffering from CED malnutrition while very few women are found to be overweight or obese in both the communities. Chi-square test doesn’t show any significant (p-0.195) difference in nutritional status between the two communities. More than 50% of Bengali Muslim women who belong to higher age group (50+) are found to be suffering from CED malnutrition while frequency of CED malnutrition is high among the middle aged Meitei women. CED malnutrition is found to be more among the Bengali Muslim women of lowest family income category but it is high among the Meitei women who belong to middle income group. Although slight negative correlation exists between BMI and age of the Bengali Muslim women but opposite picture is observed among the Meitei women. BMI of both Bengali Muslim (r=0.209, p&#60;0.01) and Meitei women (r=0.165, p&#60;0.05) demonstrate significant positive correlation with annual family income.The study indicates the affect of family income in nutritional status. However, further studies are required considering other correlated bio-social factors to get deep insight knowledge on it.

Authors: Sheikh Mohammed Iliyas , Brahmbhatt Jignesh , Kanani Jayeshkumar 
Published: January 2024

Strangulation is one type of asphyxia death in which compression of neck with ligature material without suspension of the body and commonly homicidal in nature. Self-strangulation by ligature is uncommon. It must be differentiated from homicidal strangulation, accidental strangulation and from sexual asphyxia. The ligature material in suicidal strangulation may be knotted or multiple circle around the neck or tightened like a tourniquet. The uniqueness in the present study is the use of ‘self-retaining’ nature of the ligature material. The ligature material was found in situ, completely encircled the neck. Two cases of self-strangulation are discussed here. One case was found inside closed room and other was found on the bank of the river. In both cases two self-locked ligature material was used. Both cases were meticulously investigated by postmortem examination, scene of crime and circumstantial evidences, all are suggestive of suicidal strangulation.

Authors: Rajput Alpa Singh , Rajput Arpan Singh 
Published: January 2024

Purpose of the study: This research paper proposes the use of soft mapping techniques to model the relationship between crop treatment and crop yield, with the goal of analyzing and recommending the best treatment options for crops. Soft mapping combines fuzzy logic and neural networks to create a more accurate and robust model that considers uncertain or ambiguous inputs.
Methodology: The model can be trained using data on past crop yields, treatment options, and other relevant factors such as climate and soil quality. By taking into account the inherent uncertainty and ambiguity in the input data, the soft mapping model can provide more accurate predictions and recommendations for the best treatment options for a given crop and environmental conditions.
Main Findings: The findings of this research could have important implications for the agricultural industry, particularly in the context of sustainable agriculture and food security.
Applications of this study: The proposed approach has the potential to significantly improve the analysis and decision-making processes in agriculture, helping farmers to make more informed decisions about crop treatments and ultimately increasing crop yields.
