Network Lifetime Enhancement by Elimination of Spatially and Temporally Correlated RFID Surveillance Data in WSNs
In wireless sensor networks (WSNs), radio frequency identification (RFID) plays an important role due to its data characteristics which are data simplicity, low cost, simple deployment, and less energy consumption. It consists of a series of tags and readers which collect a huge number of redundant data. It increases system overhead and decreases overall network lifetime. Existing solutions like Time-Distance Bloom Filter (TDBF) algorithm are inapplicable to the large-scale environment. Received Signal Strength (RSS) used in this algorithm is highly dependent on quality of tag and application environment. In this paper, we propose an approach for data redundancy minimization for RFID surveillance data which is a modified version of TDBF. The proposed algorithm is formulated by using the observed time and calculated distance of RFID tags. To overcome these problems, we design our approach to relevantly reduce the spatiotemporal data redundancy in the source level by adding the Received Signal Strength Indicator (RSSI) concept for energy-efficient RFID data communication in wireless sensor network scenario. We introduce in this paper the new improved idea of an existing algorithm which efficiently reduces the rate of data redundancy spatially and temporally. The implemented results overcome the limitations of existing algorithm for data redundancy reduction. Nevertheless, the performance evaluation shows the efficiency of proposed algorithm in terms of time and data accuracy. Furthermore, this algorithm supports multidimensional and large-scale environment suitable for sensor network nowadays. 2022 Lucy Dash et al. -
Climate predictors in Indian summer monsoon forecasting: a novel De-correlated RVFL ensemble strategy
Excessive rainfall and droughts harshly impact India's social and economic growth. Though several statistical methods have been used in literature to predict Indian monsoons, uncertainties cannot be ruled out. The accuracy prediction of ISMR (Indian Summer Monsoon Rainfall) is scientifically demanding. From this perspective, it is essential to explore exploiting machine learning techniques. In this paper, a novel De-correlated Regularized Random Vector Functional Link Neural Network Ensemble (DRRNE) prediction approach was proposed using Climate Predictors such as Southern Oscillation Index (SOI), Sea Surface Temperature Anomaly (SST), El-Ni Southern Oscillation (ENSO), and Dipole Mode Index (DMI) to predict ISMR. The proposed work has also investigated the predictability of climate above predictors using the DRRNE approach to predict ISMR. In addition to the predictors above, the data for an 8-year training window time series for June to September is combined and analyzed for four predictors (ENSO, DMI, SOI, and SST) to derive another predictor, ENSO-DMI-SOI-SST (EDSS). It is found that the combination of these four predictors- the EDSS- produces better accuracy than using any of the individual predictors in this study. Among the individual predictors (ENSO, DMI, SOI, and SST), the DMI predictor has shown the best predictability for ISMR prediction. Thus, the suggestedstudy concludes that the DRRNE technique with negative correlation learning may be a suitable tool for predicting the ISMR using the combined outcome of the four climate predictorsas mentioned above.

Role of Symptomatic Management in Understanding Effects of Early Integration of Palliative Care among Nonmetastatic Lung Cancer Patients on Psychological Well-Being
Aim. The impact of early referral to palliative care on quality of life for patients with lung cancer has already been discussed. However, the benefits of early integration of palliative care service (EIPCS) combined with standard oncology care for nonmetastatic lung cancer patients remain unclear. Hence, we designed a study to assess the impact of EIPCS among nonmetastatic cancer patients in India. Methods. In this randomized controlled trial study, we divided the data from 115 patients with diagnosed nonmetastatic lung cancer between age group of >18 years to ?65 years. Following clinicopathological and radiology diagnosis, patients were referred to pain and palliative medicine department. Patients were randomly assigned by palliative physicians into two groups: Group A (N = 64), those who were receiving standard oncology care (chemotherapy or radiation or both) along with EIPCS, and Group B (N = 51), receiving standard oncology care. Patients were followed up every 3 weeks up to 3 months. Primary outcomes, symptoms' burden, and psychological well-being were measured by validated tools. To define the impact of EIPCS, appropriate statistics were calculated as the mean standard deviation of the score of validated tools. Statistical significance was defined at p<0.005. Results. From the beginning, we had taken 115 patients, and on 42 days' follow-up, the number of dropout patients for Group A was 3 (due to unable to contact), and for Group B, 9 (due to physical condition). This was followed by a reassessment after 126 days where dropout patients for Group A was 4 (due to unable to contact), and for Group B, 7 (due to physical condition). Following statistical report compliance at 126 days by WEMWBS was 21.16 3.65 in Group A versus 16.1 1.93 versus in Group B and by ESAS 51.84 0.01 in Group A versus 97.64 2.18 in Group B. Conclusion. The findings of this study showed that patients with nonmetastatic lung cancer who received standard oncology care combined with EIPCS had increased the psychological well-being and reduced symptoms burden. 2024 Arunima Datta et al. -

Moderating role of location autonomy on technostress and subjective wellbeing in information technology companies
Integrating digital tools into day-to-day work activities has become an undeniable reality. However, the unprecedented reliance on technology has brought with it the escalating degrees of technostress evident through health concerns like chronic musculoskeletal problems and decreased job satisfaction. And the COVID-19 pandemic accelerated the negative impact, as IT industries adopted the hybrid workplace approach, especially in developing countries like India. This paper aims to find whether location autonomy moderates the effect of technostress on subjective wellbeing among IT employees working in a hybrid model. A purposive sampling method gathered 440 responses from IT professionals in Bengaluru tech parks. IBM SPSS and AMOS software were used to assess the constructs by SEM analysis, in line with the job demand-control theory. The results showed that location autonomy accounts for 31.6% of the variance in subjective wellbeing, while technostress explains 33.2% of the variance, with dimensions ranging from 21% to 46%. Additionally, location autonomy moderates and strengthens the link between technostress and subjective wellbeing. The study recommends that organizational leaders adopt HR policies that allow employees to choose their workplace rather than mandating a specific location for scheduled days in the week. This approach can potentially improve overall employee wellbeing, offering a favorable resolution to the challenges posed by technostress in the IT industry.

Efficient lipophilicity prediction of molecules employing deep-learning models
Lipophilicity, expressed as logP, is a significant physiochemical property and is an indicator of absorption, distribution, metabolism and elimination characteristics of drugs used in medication. It is one of the major deciding factors of the fate of a molecule to be a successful drug. Mol2vec is a convenient and unsupervised machine learning technique which produces high-dimensional vector representations of molecules and its molecular substructures. The work described here aims to simplify prediction of logP values with high-degree of accuracy by using Deep Learning (DL) models paired with Mol2vec. The work described in this paper empirically demonstrates that by using the described DL models paired with Mol2vec, one can achieve results which are much better than the conventional ML techniques as well as more complex and recent algorithms like Message-passing Neural Networks (MPNN), Graph Convolution (GC) and Spatial Graph embedding (C-SGEN). Our RMSE (Root Mean Square Error) scores from the ensemble model is one of the best reported so far in literature. The methods elaborated in this paper are simple, yet effective in predicting logP values to a great degree of accuracy due to the use of Mol2vec and standard TensorFlow operators. The models employed here can be coded and maintained with much more ease compared to the techniques of MPNN, C-SGEN or GC. 2021 Elsevier B.V. -
