False data injection attacks (FDIA) contain maliciously injecting fabricated data as to the system measurements, capable of due to improper decisions and disruptions in power distribution. Identifying these attacks is vital for preserving the reliability and integrity of the power grid. Researchers in this domain utilize modern approaches namely machine learning (ML) and deep learning (DL) for detecting anomalous forms in the data that signify the existence of such attacks. By emerging accurate and effective detection approaches, this research purposes to improve the resilience of CPS and make sure of a secure and continuous power supply to consumers. This article presents an Improved Equilibrium Optimizer with Deep Learning Enabled False Data Injection Attack Recognition (IEODL-FDIAR) technique in a CPS platform. The main purpose of the IEODL-FDIAR technique is to enable FDIA attack detection and accomplishes security in the CPSS environment. In the presented IEODL-FDIAR technique, the IEO algorithm is used for the feature subset selection process. Moreover, the IEODL-FDIAR technique applies a stacked autoencoder (SAE) model for FDIA attack detection. Furthermore, the pelican optimization algorithm (POA) can be utilized for the optimum hyperparameter chosen for the SAE algorithm which in turn boosts the detection outcomes of the SAE model. To portray the better outcome of the IEODL-FDIAR system, a wide range of simulation analyses

Although several rapid DNA isolation techniques from human peripheral blood and saliva have been developed, there are still some disadvantagesvolume, time, cost, and yield are a few notable ones. Objective: We aim to develop a rapid and inexpensive method to isolate high-molecular-weight genomic DNA from human peripheral blood and saliva that can be used for molecular biology experiments. Methods: Five DNA isolation methods with slightly varying protocols were used. High-quality DNA obtained from one specific method was further amplified by PCR and the template with good amplification was further used for performing RFLP and sequencing. Results: Out of 5 different isolation methods (R1 to R5), DNA obtained from the R4 was of good quality (molecular weight is > 10 kb and 260/280 ratio is 1.89 ± 0.2), which allows successful PCR amplification and good separation in Restriction Fragment Length Polymorphism analysis. Sequencing by the Sanger Sequencing produced a good readable sequence of an amplified fragment from Method R4 DNA. Conclusion: In the present study we have developed a simple, rapid, and cost-effective DNA isolation method, which uses low sample volume and yields good quantity and high-quality product. The DNA obtained is highly fit for molecular genetics research applications.

Given an image and a natural language question about the image, the task is to provide an accurate natural language answer. Mirroring real-world scenarios, such as helping the visually impaired, both the questions and answers are open-ended. Visual questions selectively target different areas of an image, including background details and underlying context. As a result, a system that succeeds at VQA typically needs a more detailed understanding of the image and complex reasoning than a system producing generic image captions. Moreover, VQA is amenable to automatic evaluation, since many open- ended answers contain only a few words or a closed set of answers that can be provided in a multiple choice format. We provide a dataset containing ~0.25M images, ~0.76M questions, and ~10M answers and discuss the information it provides. Numerous baseline for VQA are provided and compared with human performance. ...

This requires minimum parasitic interconnection elements along with the reduction in internal supply voltage. In view of the requirements for low power and low voltage with highly efficient circuit, an ultra low power and low voltage two stage FinFET based OP-AMP with very high unity gain bandwidth (UGB) and high open loop gain (DC gain) is proposed to achieve fast settling requirements and accuracy. FinFET design is suitable for reducing short channel effects in lower technology node. In this work cascode technique is employed for attaining high open loop gain with quick settling time and the unity gain bandwidth is improved by the gain stage along the miller capacitor feedback path. The proposed FinFET based OP-AMP offers open loop gain of 92 dB, unity gain bandwidth of 230 MHz and having power consumption of only 15.43 μW. All the simulations are performed using Cadence in 45nm technology.

Globally, almost three-quarters of neonatal deaths occur within the first seven day of delivery. Postnatal period has been identified as one of the important periods when information concerning neonatal danger signs is passed on to the mother and this assist the mothers to identify children at risk and seek medical assistance as soon as possible. The objective of this study is to assess the knowledge regarding danger signs of neonatal illness among mothers. A Descriptive study was conducted on 110 mothers in postnatal ward of hospital by purposive sampling technique. Data was collected by using self structured questionnaire. The result of the study revealed that the mean±SD score was 6.20±2.74 for the knowledge among the mothers regarding danger signs of neonatal illness. It was found that half of the mothers that is 61 out of 110 had average knowledge (55.5%) regarding danger signs in neonate illness, 46 respondents had average knowledge and only 1and 2 out of 110 mothers had good and excellent knowledge respectively. There was significant association between the knowledge among mothers regarding danger signs of neonatal illness and educational status of mothers at the level of 0.01 and with source of knowledge regarding health at the level of 0.05. The findings of study conclude that there is need to enhance the knowledge among mothers regarding danger signs of neonatal illness.

The receptor has been found to be selective toward La3+ with ∼70 fold fluorescence enhancement due to a combined effect of keto-enol tautomerism inhibition and chelation enhanced fluorescence (CHEF) with a detection limit of 3.91 ×10-6 M. In addition receptor is also able to sense CN- with a detection limit of 3.55 × 10-6 M via deprotonation effect, justifying its multiple analyte sensing behaviour. Hence the current analytical methodology improves the sensing activity of the probe and also provides a greener alternative for La3+ and CN - detection.

However, how it starts and propagates is unknown.Here we show that amyloid-β released by microglia in association with large extracellular vesicles (Aβ-EVs) alters dendritic spine morphology in vitro, at the site of neuron interaction, and impairs synaptic plasticity both in vitro and in vivo in the entorhinal cortex–dentate gyrus circuitry. One hour after Aβ-EV injection into the mouse entorhinal cortex, long-term potentiation was impaired in the entorhinal cortex but not in the dentate gyrus, its main target region, while 24 h later it was also impaired in the dentate gyrus, revealing a spreading of long-term potentiation deficit between the two regions. Similar results were obtained upon injection of extracellular vesicles carrying Aβ naturally secreted by CHO7PA2 cells, while neither Aβ42 alone nor inflammatory extracellular vesicles devoid of Aβ wer...

To perceive the fall detection algorithm, the angles acquired by the electronic compass and the waveform sequence of the tri-axial accelerometer on the smart phone are used as the system inputs. The obtained signals are used to produce an ordered feature sequence and then tested in consecutive way by the proposed cascade classifier for identification purpose. As soon as equivalent characteristic is confirmed by the classifier at the current state, it can continue to the state; contrarily the system will come back to the initial state and halt for the emergence of another feature sequence. When a fall accident event is diagnosed the victim’s position can be acquired by global positioning system (GPS) and forwarded to the rescue centre via 3G network so that immediate medical help can be provided.With the proposed cascaded classification architecture, the computational...

In India, large number of population is dependent on livestock for their livelihood. India has vast store of livestock breeds but milk productivity is still low in the country as compared to many countries. Various livestock species contributes differently to the income of poor and marginal farmers but among different livestock species, cattle and buffalo are largely maintained by farmers to earn their livelihood through sale of milk. There is need to adopt new technologies and package of practices by farmers to enhance the income from rearing of livestock. These include breeding, nutritional, management and health interventions. Dairy technologies such as processing of milk and augmentation of nutritive value of milk are needed to be adopted to increase the income of farmers. Organic farming and Integrated Farming System supplement all other interventions in enhancing the returns to farmers. Keywords: livestock, farmer’s income, packa...
