Enhancing Missing Values Imputation through Transformer-Based Predictive Modeling
Authors: Hina Ayub , Harun Jamil
Published: January 2024

This paper tackles the vital issue of missing value imputation in data preprocessing, where traditional techniques like zero, mean, and KNN imputation fall short in capturing intricate data relationships. This often results in suboptimal outcomes, and discarding records with missing values leads to significant information loss. Our innovative approach leverages advanced transformer models renowned for handling sequential data. The proposed predictive framework trains a transformer model to predict missing values, yielding a marked improvement in imputation accuracy. Comparative analysis against traditional methods—zero, mean, and KNN imputation—consistently favors our transformer model. Importantly, LSTM validation further underscores the superior performance of our approach. In hourly data, our model achieves a remarkable R2 score of 0.96, surpassing KNN imputation by 0.195. For daily data, the R2 score of 0.806 outperforms KNN imputation by 0.015 and exhibits a notable superiority of 0.25 over mean imputation. Additionally, in monthly data, the proposed model’s R2 score of 0.796 excels, showcasing a significant improvement of 0.1 over mean imputation. These compelling results highlight the proposed model’s ability to capture underlying patterns, offering valuable insights for enhancing missing values imputation in data analyses.

Nutritional value of extracted soybean, full fat soya and maize gluten meal proteins in comparison to a fish meal based reference diet for fingerling tilapia
Authors:   Simon Davies, Bell Matt
Published: January 2024

A two-month investigation evaluated potential selected plant protein sources compared to fish meal protein in scientifically formulated diets for fingerling tilapia (Oreochromis mossambicus). Six nutritionally balanced diets: one reference (control) diet (fish-meal-based diet), three selected plant proteins (solvent extracted soybean, full fat soybean, and maize gluten) were substituted in the LT (Low Temperature dried) fish-meal-based control diet protein at 50 % respectively, and the remaining diets were replaced with 75% inclusion of solvent extracted soybean and maize gluten meals. Results showed that SESB50, FFSB50 and MG50 fed tilapia did not appreciably differ in their growth performance (final mean weights of 12.07, 10.75 and 9.18% respectively) with a final mean weight of 14.95g being significantly superior for the fish meal control (CO) group. Substitution of fish meal diet with solvent-extracted soybean and maize gluten at levels of 75% gave the poorest growth performance and Feed Efficiency (FE) (7.01g final weight, 51% FE). However, the MG50 dietalso showed some inferior feed utilisation performance. However, tilapia fed on a full fat soybean diet (FFSB50) did not vary significantly from the control (CON) diet in terms of Apparent Net Protein Utilisation (ANPU) at 34.20 and 37.53 percent respectively. Whilst this preliminary study concluded that limitations on the use of the selected plant proteins in diets for tilapia are apparent, several approaches that could result in the future improvement of the nutritional value of soybean and maize gluten products for use in fish diets are also stated.

Published: January 2024

The composition of seed and cake volatiles of Pongamia pinnata (L) Pierre extracted by solid phase micro extraction was analyzed by GC and GC-MS. A total of 84 and 81 volatile compounds were identified from the headspace samples of seed and cake, respectively. The volatiles belonged to ten major groups of compounds comprising hydrocarbons (aliphatic and aromatic), terpenoids, alcohols, phenols, aldehydes and ketones, acids, esters, oxo compounds, sulphur compounds and nitrogen compounds. The most abundant individual compound present in the volatile fraction of both seed and cake was 2-chloroacetophenone (19.58% and 19.47%, respectively). Significant differences in the proportion of sulphur compounds, phenols and nitrogenous compounds between seed and cake were observed while there were little differences in others. The study found several compounds in the volatile fractions of both seed and cake reported to have an adverse effect on pests and pathogens of crops. This finding provides the first experimental evidence for the use of Pongamia volatiles as a bio-pesticide for crop protection.

Geopolitics of the Indo-Pacific Region: Current Status and Prospects of Comptetition between Major Powers
Authors: Kato Yoichi
Published: January 2024

The geopolitical and geoeconomic conditions in the Indo-Pacifi c region have been undergoing a variety of changes at a rapid pace. In this paper, the changes are examined from the perspectives of the four major powers in the region: China’s overreach and revision of the “Belt and Road Initiative” (BRI), United States’ hardening stance toward China, India’s sense of caution toward China, and Japan’s changes in strategy toward China brought about by the “Free and Open Indo-Pacifi c” (FOIP) strategy. Currently, projects of the BRI are being implemented across a wide geographical range including the Indo-Pacific region, despite criticisms regarding ‘debt traps’ and ‘new colonialism’ from many countries. As China’s infl uence grows, small and medium-sized countries of the region are playing a role in the struggle between United States and Japan’s FOIP and China’s BRI. China’s aim to expand its own national power challenges the previously U.S.-dominated order, while Japan is in a position to advocate maintenance of the existing order and while India sees a multipolar order as more desirable. Although China’s growing power in Asia is appearing sooner than expected, it is also evident that the US will not concede its leadership position in the Indo-Pacific. The fundamental question is whether the dominance of the United States that has prevailed since the end of Cold War can be sustained, and if it cannot, how the new order will be formed.

Our gaze on technology is often short-sighted, even cross-eyed. It focuses only on technological novelty and forgets the other half of the issue: human beings and their ways of using technology.
My new book Confidenze Digitali: Vizi e virtù dell’innovazione (‘Digital intimacy: Vices and virtues of innovation’) starts from everyday life situations that we all know well and from habits that are as widespread as they are unconscious, analyzing key features that characterize our relationship with technology and more in general contemporary society.
For example, why do big tech companies, chatbot and virtual assistants address us confidentially as friends, rather than customers? Why do we often receive kisses and hugs in messages, even from people we do not really know that well? If the person sitting next to us looks at their telephone, why are we likely to do the same within thirty seconds? Why do we not want to pay to read daily news anymore, but we are ready to donate money to Wikipedia? Where does the extraordinary spread of video tutorials on «how to do…» anything – from fresh bread to barbecues, from dying hair to repairing a roller shutter – come from? And what does it say about us?

Behind every scientific advance, behind every discovery, but also behind every mistake and every unproven hypothesis... behind science, in short, there are stories to be told. Indeed, as one of the monographs in this volume points out: «Evidence is accumulating that storytelling can be one of the most effective means for communicating sciences». In Metode Science Studies Journal, we give researchers a voice to tell their own stories, or the stories behind their research. How fossil remains from the past are discovered and what they mean to the region where they are found; how images accompany, document, and help to disseminate science; how we learn more about our primate relatives; and how we present the story behind the science to the general public. Four monographs, with the collaboration of leading experts and researchers in their respective fields, that offer us fragments, pieces of science, so necessary to understand today’s world and its challenges. At a time when reason is losing ground to populism and it is often difficult to distinguish reliable signals from the noise of disinformation, scientific journals are more necessary than ever. Perhaps the clearest example of this is the implementation of artificial intelligence in our daily lives. We watch the progress of this technology with a mixture of wonder and hope, but also uncertainty and suspicion. This is why it is important to analyse the applications of the technology, as Professor Massimiano Bucchi points out in the article that opens this volume, and to provide the reader with a context for the current situation. And to understand it, science from a multidisciplinary point of view is more necessary than ever. How can we explain the applications of artificial intelligence without analysing its impact on society, culture, and work? How can we discuss climate change without including a geopolitical and economic analysis? And above all, how can we understand reality without science?
Photo-fixation of Ag onto TiO2 Powder Films for Improved Photocatalytic Activity and Atomic-absorption Determination of Residual Noble Metal in Dyes Solution

For the first time, we photo-fixed silver ions (10–2, 10–3, and 10–4 M) onto films prepared from commercial TiO2 powder via ultraviolet illumination. The synthesis process is straightforward and environmentally friendly. The nanostructures are characterized by SEM, XRD, FAAS, and UV/Vis spectroscopy for the photocatalytic properties. The X-ray diffraction pattern demonstrated the phase of the anatase TiO2 structure. Flame Atomic Absorption Spectrometry is used as a simple way to determine the Ag+ content in solutions from the heterogeneous photocatalysis under UV illumination. The research shows that at the end of the degradation process, no silver ions are observed for both dyes – malachite green and methylene blue. The formation of stable intermediates by the reaction of OH with the triarylmethane dye during the photocatalysis resulted in faster degradation of malachite green than methylene blue. In comparison to pure TiO2, the TiO2/Ag films have higher photocatalytic efficiency. The reason is the presence of silver, which leads to a decrease in the recombination of pairs of charges.
Gene regulatory patterning codes in early cell fate specification of the C. elegans embryo

Pattern formation originates during embryogenesis by a series of symmetry-breaking steps throughout an expanding cell lineage. In Drosophila, classic work has shown that segmentation in the embryo is established by morphogens within a syncytium, and the subsequent action of the gap, pair-rule, and segment polarity genes. This classic model however does not translate directly to species that lack a syncytium – such as Caenorhabditis elegans – where cell fate is specified by cell-autonomous cell lineage programs and their inter-signaling. Previous single-cell RNA-Seq studies in C. elegans have analyzed cells from a mixed suspension of cells from many embryos to study late differentiation stages, or individual early stage embryos to study early gene expression in the embryo. To study the intermediate stages of early and late gastrulation (28- to 102-cells stages) missed by these approaches, here we determine the transcriptomes of the 1- to 102-cell stage to identify 119 embryonic cell states during cell fate specification, including ‘equivalence-group’ cell identities. We find that gene expression programs are modular according to the sub-cell lineages, each establishing a set of stripes by combinations of transcription factor gene expression across the anterior-posterior axis. In particular, expression of the homeodomain genes establishes a comprehensive lineage-specific positioning system throughout the embryo beginning at the 28-cell stage. Moreover, we find that genes that segment the entire embryo in Drosophila have orthologs in C. elegans that exhibit sub-lineage-specific expression. These results suggest that the C. elegans embryo is patterned by a juxtaposition of distinct lineage-specific gene regulatory programs each with a unique encoding of cell location and fate. This use of homologous gene regulatory patterning codes suggests a deep homology of cell fate specification programs across diverse modes of development.

Increasing evidence supports a role for deficient Wnt signaling in Alzheimer’s disease (AD). Studies reveal that the secreted Wnt antagonist Dickkopf-3 (DKK3) colocalizes to amyloid plaques in AD patients. Here, we investigate the contribution of DKK3 to synapse integrity in healthy and AD brains. Our findings show that DKK3 expression is upregulated in the brains of AD subjects and that DKK3 protein levels increase at early stages in the disease. In hAPP-J20 and hAPPNL-G-F/NL-G-F mouse AD models, extracellular DKK3 levels are increased and DKK3 accumulates at dystrophic neuronal processes around plaques. Functionally, DKK3 triggers the loss of excitatory synapses through blockade of the Wnt/GSK3β signaling with a concomitant increase in inhibitory synapses via activation of the Wnt/JNK pathway. In contrast, DKK3 knockdown restores synapse number and memory in hAPP-J20 mice. Collectively, our findings identify DKK3 as a novel driver of synaptic defects and memory impairment in AD.
“Ühel mehel käind naine undiks…”. Saaremaalt kogutud libahundimuistenditest

The articles discusses the material relating to werewolves collected from the island of Saaremaa that is stored at the Estonian Folklore Archives. It is presumed that belief in werewolves persisted longer on Saaremaa than in many other Estonian regions. Interpretations are offered to the werewolf legends. For this purpose, historical background data and information on the significance of wolves in the mental world of the Estonian peasant is introduced. Werewolf legends represent alternative strategies of coping with difficulties (the danger of famine, tension between genders and social classes) that defied existing social norms. As relatively many tales of female werewolves have been collected from Saaremaa, they are given special attention. The popularity of female werewolves on Saaremaa, and in Estonia, can be connected with the strong status of women among the Estonian and Livonian peasants and with the hypothesis of the matrilineality of these societies in prehistoric times.

Background

Feature selection is a vital process in data mining and machine learning approaches by determining which characteristics, out of the available features, are most appropriate for categorization or knowledge representation. However, the challenging task is finding a chosen subset of elements from a given set of features to represent or extract knowledge from raw data. The number of features selected should be appropriately limited and substantial to prevent results from deviating from accuracy. When it comes to the computational time cost, feature selection is crucial. A feature selection model is put out in this study to address the feature selection issue concerning multimodal.

Methods

In this work, a novel optimization algorithm inspired by cuckoo birds’ behavior is the Binary Reinforced Cuckoo Search Algorithm (BRCSA). In addition, we applied the proposed BRCSA-based classification approach for multimodal feature selection. The proposed method aims to select the most relevant features from multiple modalities to improve the model’s classification performance. The BRCSA algorithm is used to optimize the feature selection process, and a binary encoding scheme is employed to represent the selected features.

Results

The experiments are conducted on several benchmark datasets, and the results are compared with other state-of-the-art feature selection methods to evaluate the effectiveness of the proposed method. The experimental results demonstrate that the proposed BRCSA-based approach outperforms other methods in terms of classification accuracy, indicating its potential applicability in real-world applications. In specific on accuracy of classification (average), the proposed algorithm outperforms the existing methods such as DGUFS with 32%, MBOICO with 24%, MBOLF with 29%, WOASAT 22%, BGSA with 28%, HGSA 39%, FS-BGSK 37%, FS-pBGSK 42%, and BSSA 40%.
