Local languages based information storage and retrieval system is essential for any online digital repository system. This paper reports the development of an interface in Bengali that allows users not only browsing and searching Indic-script based documents but also allows administrator performing various system level operations. This paper briefly describes the origin and key characteristics of Indic-scripts along with their encoding in Unicode standard with special reference to Bengali language. It also demonstrates the development processes of Bengal-script based information representation and retrieval (IRR) system viz. BURA (Burdwan University Research Archive) using different open standard and open source software (OSS) including different factors essential for building such successful Indic-script based multilingual digital libraries. The suggested strategies may help digital library developers to design an appropriate multi-script based information access services in any other Indic-script based languages.

Indian subcontinent is a birthplace of multilingual people where documents such as job application form, passport, number plate identification, and so forth is composed of text contents written in different languages/scripts. These scripts may be in the form of different indic numerals in a single document page. Due to this reason, building a generic recognizer that is capable of recognizing handwritten indic digits written by diverse writers is needed. Also, a lot of work has been done for various non-Indic numerals particularly, in case of Roman, but, in case of Indic digits, the research is limited. Moreover, most of the research focuses with only on MNIST datasets or with only single datasets, either because of time restraints or because the model is tailored to a specific task. In this work, a hybrid model is proposed to recognize all available indic handwritten digit images using the existing benchmark datasets. The proposed method bridges the automatically learnt features of Capsule Network with hand crafted Bag of Feature (BoF) extraction method. Along the way, we analyze (1) the successes (2) explore whether this method will perform well on more difficult conditions i.e. noise, color, affine transformations, intra-class variation, natural scenes. Experimental results show that the hybrid method gives better accuracy in comparison with Capsule Network.

Various models have been presented to describe early Southeast Asian political formations that draw on both indigenous and imported Indic ideas. The most influential of these are the "Mandala" (Wolters 1968, 1982, 1999), "Galactic" (Tambiah 1976), "Negara" (Geertz 1980), and Anderson's 1972 "The idea of power in Javanese culture." This paper represents an initial attempt to compare the salient features of these models with historical and archaeological data from South Sulawesi where, exceptionally and importantly, societies developed independently of Indic ideas. South Sulawesi is unique in being the only region of maritime Southeast Asia where there are sufficient written and oral sources, often substantiated by archaeological data, to document the social evolution of its society from scattered, economically self-sufficient communities with ranked lineages practicing swidden agriculture to large political units (kingdoms) constructed around indigenous cultural and political concepts with economies based on wet-rice agriculture. This wealth of data provides us with a much more detailed picture of the emergence, development and support structures of early kingdoms than found in the models, which makes South Sulawesi of fundamental importance in understanding the social and economic evolution of pre-Indic influenced Austronesian societies in Maritime Southeast Asia.

World history today has been greatly influenced by the fact that it was the revolution in naval power during the past two centuries that made the world truly global. This has led to a new master narrative that re-framed five millennia of recorded history in order to explain the ultimate triumph of the maritime economies. The result of such revision is to underestimate and distort the role of continental Eurasia in the shaping of the three key civilizations that developed independently and remain distinct: the Mediterranean, the Indic and the Sinic. Only by a fuller reappraisal of the linkages of trade and war dominated by the Eurasian central forces for most of history can we understand the global pressures perennially at work. By setting the continental and the maritime in their total historical context and recognizing their importance today, we can better explain what is happening and what is likely to continue to influence the course of world history.

The larval development of Parupilumnus trispinosus Sakai, 1965 completed in the laboratory consisted of four zoeal stages and one megalopal stage. Completion of the lanral development required at least 18 days at 20-25"C. The morphology of the lanrae of each stage is described in detail, and comparisons are made with larvae of other 11 species of the subfamily Pilumninae. Although, the zoeae of the subfamily Pilumninae show almost consistent characteristics of the mouthpart appendages, in the characteristics of the carapace spines and the abdominal lateral knobs they can be divided into five groups: (1) the genera Heteropanope and Heteropilumnus, (2) the genera Actumnus and Pilumnus, (3) Pilumnopeus makiona and P sewutifrons, (4) Porupilumnus trispinosus, and (5) Pilumnopeus eucratoides and. p indic${\alpha}$.

Migratory insect pest populations migrate from the southern China to Korea through jet streams. In Korea, 5 major migratory insect species are important, i.e. Nilaparvata lugens, Sogatella furcifera, Laodelphax striatellus, Cnaphalocrocis medinalis and Mythimma separate, which are damages to the major crops, rice. This study was conducted from late July 2016 to early September 2016 and from July 2017 to August 2017 in rice paddy of Jeolla-province. C. medinalis and M. separata collected using pheromone traps, while N. lugens, S. furcifera and L. striatellus collected using 3 methods (visual surveys, sweeping surveys, sticky traps). SADIE (Spatial Analysis by Distance IndicEs) among geostatistics was used to analyze migratory insect pests. SADIE was used to analyze spatial distribution and index of aggregation $I_a$, index of clustering $V_i$, $V_j$ were used to investigate the spatial distribution. Also, the clustering indices were mapped as red-blue plot. C. medinalis and M. separata showed different distribution based on SADIE spatial aggregation analysis and red-blue plot analysis. Initial spatial distributions of L. striatellus and other planthoppers were differed for sampling location and time.

The transport phenomena of alkali metal chlorides through poly(2 hydroxyethyl methacrylate) hydrogel membrane have been studied using electrodialysis. The hydrogel membranes were prepared by the polymerization of 2-hydroxvethyl methacrylate in the presence of 45%(V/V) H2O and ethyleneglycodimethacrylate. The initiator used in the polymerization was azobismethylisobutyrate (AMIB) prepared from azobisiobtyronitrile (AIBN) using Mortimer method. The permeability of alkali metal chlorides such LiCl, NaCl and KCI at 50 voltage was obtained. The permeability of NaCl was also observed at 30, 40, 50, and 60 voltages respectively. The concentration of solutes permeated through the membrane was measurer by flame photometry. The experimental results have been discussed with the comparison of apparent solute molecular size, the self-diffusion coefficient of solutes, the transport number of cations in aqueous solution. These indic aloes that poly(2 hydroxyethyl methacrylate) hydrogel membrane shows a specific selectivity for sodium ion.

The archaeological remnants of coastal ports and shipwrecks serve as invaluable heritage sites that provide profound insights into historical maritime activities conducted by humans. Cross-regional voyages occurred as early as the beginning of the first millennium, aided by the increasing knowledge of the monsoons. Along with expanding intra- and inter-sailing routes, the improved seaworthiness of vessels facilitated the movement of people and seaborne commodities. The names of the Indic, Kunlun, and Persian ships appear in various historical accounts written in the latter half of the first millennium, and the structural details and characteristics can be physically examined by looking at shipwrecks. Southeast and East Asian shipwrecks from the eighth to the fourteenth century provide a perspective on the dynamism of types of seagoing ships involved in long-distance trade. By examining the remnants of cargo being transported by these ships, we begin to understand how the system of cross-regional shipment of heavy and bulky items, metal objects, fragrant woods, glass, and ceramics sustained and impacted the religions, societies, culture, and regional economies. Furthermore, it helps define the Maritime Silk Route heritage to be managed and protected. As such, this paper gives the archaeological evidence of port ruins and wrecks and also introduces, as an example, a case from Central Vietnam.

This research proposes a novel approach for Tamil Handwritten Character Recognition (THCR) that combines feature selection and ensemble learning techniques. The Tamil script is complex and highly variable, requiring a robust and accurate recognition system. Feature selection is used to reduce dimensionality while preserving discriminative features, improving classification performance and reducing computational complexity. Several feature selection methods are compared, and individual classifiers (support vector machines, neural networks, and decision trees) are evaluated through extensive experiments. Ensemble learning techniques such as bagging, and boosting are employed to leverage the strengths of multiple classifiers and enhance recognition accuracy. The proposed approach is evaluated on the HP Labs Dataset, achieving an impressive 95.56% accuracy using an ensemble learning framework based on support vector machines. The dataset consists of 82,928 samples with 247 distinct classes, contributed by 500 participants from Tamil Nadu. It includes 40,000 characters with 500 user variations. The results surpass or rival existing methods, demonstrating the effectiveness of the approach. The research also offers insights for developing advanced recognition systems for other complex scripts. Future investigations could explore the integration of deep learning techniques and the extension of the proposed approach to other Indic scripts and languages, advancing the field of handwritten character recognition.

In this study, we analyzed the gene expression data of Saccharomyces cerevisiae obtained from Holstege et al. 1998 to understand the relationship between expression level and nucleotide sequence of a gene. First, the correlation between gene expression and percent composition of each type of nucleotide was computed. It was observed that nucleotide 'G' and 'C' show positive correlation (r ${\geq}$ 0.15), 'A' shows negative correlation (r ${\approx}$ -0.21) and 'T' shows no correlation (r ${\approx}$ 0.00) with gene expression. It was also found that 'G+C' rich genes express more in comparison to 'A+T' rich genes. We observed the inverse correlation between composition of a nucleotide at genome level and level of gene expression. Then we computed the correlation between dinucleotides (e.g. AA, AT, GC) composition and gene expression and observed a wide variation in correlation (from r = -0.45 for AT to r = 0.35 for GT). The dinucleotides which contain 'T' have wide range of correlation with gene expression. For example, GT and CT have high positive correlation and AT have high negative correlation. We also computed the correlation between trinucleotides (or codon) composition and gene expression and again observed wide range of correlation (from r = -0.45 for ATA r = 0.45 for GGT). However, the major codons of a large number of amino acids show positive correlation with expression level, but there are a few amino acids whose major codons show negative correlation with expression level. These observations clearly indic ate the relationship between nucleotides composition and expression level. We also demonstrate that codon composition can be used to predict the expression of gene in a given condition. Software has been developed for calculating correlation between expression of gene and codon usage.
