Big data has ushered in an era of unprecedented access to vast amounts of new， unstructured data， particularly in the realm of sensitive information. This data presents unique opportunities for enhancing risk alerting systems， but also poses challenges in terms of extraction and analysis due to its diverse file formats. This paper proposes the utilization of a DAE-based (Deep Auto Encoders) model for projecting risk associated with financial data. The research delves into the development of an indicator assessing the degree to which organizations successfully avoid displaying bias in handling financial information. Results from simulation experiments demonstrate the superior performance of the DAE algorithm， showcasing fewer false positives， improved overall detection rates， and a noteworthy 9% reduction in failure jitter. The optimized DAE algorithm achieves an accuracy of 99%， surpassing existing methods， thereby presenting a robust solution for sensitive data risk projection.

Pomegranate rind is abundantly available as a waste material. Pomegranate Rind Extract (PRE) can be applied to cotton fabrics for its natural colours, as a mordanting agent and also for imparting certain functional properties such as fire retardancy and antimicrobial properties. This paper reviews the feasibility of Pomegranate Rind Extract to improve the functional properties of cellulosic fabrics. Studies show that varying concentrations and higher temperatures that were used to apply the extract on the fabric, resulted in enhanced functional properties. At a particular concentration, the treated fabric showed a 15 times lower burning rate in comparison with the control fabric. Also, antimicrobial efficacy has been observed against Gram-positive and Gram-negative bacteria. Due to the natural colouring material, it can be used as a natural dye on cotton material. The fire retardancy of pomegranate rind extract was tested on jute material under varying alkalinity. Research has indicated that pomegranate rind extract could be used to dye polyamide as well. The rubbing and wash fastness of the finished fabrics is good. The light fastness was fair, and its antibacterial efficiency against tested bacteria was good.

In the present study, morphology, size distribution, structure, biocompatibility and magnetic properties of potassium ferrite nanoparticles （KFeO2 NPs）, synthesized by conventional sol-gel method have been reported. The formation of spherical nanoparticles with orthorhombic structure has been confirmed by scanning electron microscopy and X-ray diffraction. The particle size, as obtained by transmission electron microscopy has been found to be in the range of 4-7 nm. Further, the size distribution has been scrutinized using Analyse-it software, where a platykurtic feature in the size distribution was observed. Fourier transform-infrared spectroscopy and thermogravimetric analysis showed the formation of metal （Fe, K） bonds at Neel temperature of 337℃. Vibrating sample magnetometer analysis revealed the superparamagnetic behaviour of the synthesized KFeO2 NPs, with saturation magnetization of 25.72 emu/g. In vitro cytotoxicity test, using MTTassay, on T cell lines （Jurkat cells） showed that KFeO2 NPs are biocompatible at a particle concentration of 100μg/ml.

High entropy pyrochlores(HEP)are potential candidates as dispersoids in the oxide dispersed strengthened steels or alloys,which can be used in nuclear reactors and supercritical *** the first time,HEP oxides Y_(2)(TiZrHfMoV)_(2)O_(7) were synthesized with Y_(2)Ti_(2)O_(7) as a base structure with the B site(Ti)substituted with five cations through reverse co-precipitation technique in the nanocrystalline form at lowest synthesis *** synthesis parameters for Y_(2)(TiZrHfMoV)_(2)O_(7)(5C)and other derived compositions(five compositions of four cationic systems with each cation eliminated at B site from 5 C)are optimised to obtain lower crystallite and particle sizes.5C has a smaller crystallite size(27 nm)than other single-phase *** cation’s influence,oxidation state,and oxygen vacancy in the phase formation were analysed through *** single-phase HEPs are consolidated through spark plasma sintering.Y_(2)(TiZrHfMo)_(2)O_(7)(4 C-V)shows the highest hardness among the compositions reported so far due to its finer grain size,and Y_(2)(TiHfMoV)_(2)O_(7)(4 C-Zr)has a higher Young’s modulus compared to other single-phase composition due to its higher degree of order in the structure.

Erosion corrosion performance of 6061 aluminum alloy in simulated sea water slurry was investigated under multi-phase jet impingement conditions. The main objective of the work is to study erosion–corrosion of a material with engineering application and mitigate it using eco-friendly green inhibitor. Experiments were performed with the sand concentration of 0.3% and 0.3 μm size. The effect of temperature and flow rate on the performance of inhibitor was explored. Electrochemical methods were adopted for erosion-corrosion measurements. Experiments revealed that starch could mitigate erosion-corrosion with a maximum reduction efficiency of 58% at temperature of 303 K and flow rate of 4 L·min–1. Inhibition efficiency decreased with increase in flowrate and temperature. EIS spectrum demonstrated that the corrosion process in the presence on inhibitor was both charge transfer and mass transfer controlled. A key role of hydrodynamics in the performance of corrosion inhibitor was confirmed by the present study.

Dengue virus,a member of the Flavivirus genus in the Flaviviridae family,has four serotypes(DEN-1 to DEN-4),and is responsible for both mild and severe dengue fever(dengue hemorrhagic fever and dengue shock syndrome)[1].Dengue cases are under reported in India and the cases are treated clinically based on the clinical triage of symptoms[2].Nonstructural protein(NS1)antigen is a highly conserved glycoprotein found in Flavivirus group such as Dengue,Zika,and Japanese encephalitis *** detection of NS1 antigen,IgM and IgG antibody in a single cassette is used for testing primary and secondary dengue *** diagnosis of disease progression associated with severe dengue and accessibility to appropriate medical care reduces severe dengue fatality rates to less than 1%.This retrospective study,conducted from January 2021 to December 2021 in the tertiary care hospital,South India,was aimed to determine the seroprevalence of dengue adult patients with acute febrile illness.
