Nations within a nation: variations in epidemiological transition across the states of India, 1990–2016 in the Global Burden of Disease Study
18% of the world's population lives in India, and many states of India have populations similar to those of large countries. Action to effectively improve population health in India requires availability of reliable and comprehensive state-level estimates of disease burden and risk factors over time. Such comprehensive estimates have not been available so far for all major diseases and risk factors. Thus, we aimed to estimate the disease burden and risk factors in every state of India as part of the Global Burden of Disease (GBD) Study 2016
TECHNOLOGY Reduction of Total Harmonic Distortion Using Filtered SVPWM in Multiphase Voltage Source Inverters
In recent years, multiphase PWMs have been proposed because of their increased efficiency, reduced torque pulsation, improved fault tolerance, and lower power handling requirement by adopting multiphase machines. In the digital implementation, multiphase reference voltages are sampled and fed into the digital modulator to produce gating signals at a constant clock rate f. This means a finite pulse-width resolution because the gating state transition can only occur at some specific time instants depending on f. This will result in a deviation of produced phase voltages from the desired phase voltages, i.e., increasing harmonic distortion especially for a small modulation index signal. In the present paper a filtered space-vector pulse-width modulation (SVPWM) considering finite pulsewidth resolution is proposed to produce a switching sequence with reduced baseband harmonics for multiphase voltage source inverters (VSI). This is achieved by incorporating a pseudo feedback loop regarding weighted voltage difference between desired and produced phase voltages

Agronomic Management of CRIDA 18RA rainfed experiment was conducted at two contrasting rainfall situations of two different states of South India viz., Hyderabad
(Telangana) and Tirupathi (Andhra Pradesh) during 2007-08 to standardize the optimum sowing time, plant densities and
fertiliser dose for horsegram variety CRIDA 18R released and recommended for cultivation in South India. Results showed
that the second fortnight of August and first fortnight of November were suitable optimum times of sowing in Hyderabad
and Tirupathi regions respectively due to receipt of rainfall from South West monsoon and North East monsoon at respective
locations. Plant densities of 3.33 lakh per hectare with or without 10N + 20P2O5 fertilizer dose yielded higher seed in both
the regions. However when the sowing was delayed, wisest decision might be to continue the plant densities of 3.33 lakh
population per hectare with or without fertilizer. The results revealed that CRIDA-18R responded to fertilizer up to 10 N
+20 P2O5 kg ha-1 with 3.33 lakh plant density but for the varied optimum time of sowing at two different centers with
occurrence of favourable rainfall situations, revealing a very flexible sowing time for CRHG-18R in South India.Not Availabl

Not AvailablePrincipal component analysis has been explored for assessing the consistency of 14 plant traits for sunflower growth using multivariate data of 6 field experiments conducted during kharif 1994 to 1999 seasons on rainfed alfisol. Seven genotypes have been used in the study viz., Guj-sun-1, MSFH-8, MSFH-17 KBSH-1, Jwala, Pac-36 and Morden. Observations were recorded on leaf nitrogen, leaf area, leaf weight, leaf number, stem nitrogen, stem weight root length, root weight, stomatal conductance, photosynthesis, total biomass on 30, 45 and 60 days after sowing (DAS) and flower head diameter and flower head weight on 45 and 60 days after sowing in each season. The first two principal components have extracted about 80% of variance in the data of different plant traits on different days after sowing. The consistency of plant traits has been assessed by examining correlations between different plant traits and the distribution of loadings of plant traits on the first two leading principal components 30, 45 and 60 days after sowing. The results have indicated that stem weight and lead number on the 30th day, leaf area and leaf weight on the 45th day and leaf area, leaf weight and total biomass on the 60th day after sowing had significantly higher loadings on the 1st principal component. Similarly, root length on the 30th day, flower head diameter and flower head weight on the 45th day and root length and photosynthesis on the 60th day after sowing had significantly higher loadings on the 2nd principal component. Based on a graphic plot of the loadings, root length (30 and 60 DAS), stomatal conductance (30, 45 and 60 DAS) and photosynthesis (30 DAS) were found to be consistent since their loadings on the 1st principal component had high mean values with low standard deviations. Similarly, stem nitrogen (45 and 60 DAS), stomatal conductance (45 DAS), photosynthesis (30 DAS), leaf nitrogen (60 DAS), root length (30 DAS), flower head diameter (45 DAS) and flower head weight (45 DAS) were also consistent since their loadings on the 2nd principal component had high mean values with low standard deviations.Not Availabl

Not AvailableGrowth and yield responses of castor bean (Ricinus communis L.) to two elevated CO2 levels (550 and 700 ppm) were evaluated up to the maturity of first order spikes in open top chambers (OTCs). The growth characteristics – root and shoot lengths, root volume, root:shoot ratios, leaf area, dry weights of different plant parts, leaf area duration and crop growth rate increased with 550 and 700 ppm of CO2 levels compared with ambient control. The spike length, pod and seed yield of first order spikes increased under enhanced CO2 levels over ambient control. Elevated CO2 levels significantly increased the total biomass and yield of castor bean, however enhanced CO2 levels per se did not changed the content and quality of the castor oil. A positive response of castor bean to increased CO2 concentrations is a good indication for its future existence in potentially changed climatic conditions.NPCC, ICA

ChatGPT's Ability to Assess Quality and Readability of Online Medical Information: Evidence From a Cross-Sectional Study
Introduction
Artificial Intelligence (AI) platforms have gained widespread attention for their distinct ability to generate automated responses to various prompts. However, its role in assessing the quality and readability of a provided text remains unclear. Thus, the purpose of this study is to evaluate the proficiency of the conversational generative pre-trained transformer (ChatGPT) in utilizing the DISCERN tool to evaluate the quality of online content regarding shock wave therapy for erectile dysfunction.
Methods
Websites were generated using a Google search of “shock wave therapy for erectile dysfunction” with location filters disabled. Readability was analyzed using Readable software (
Readable.com
, Horsham, United Kingdom). Quality was assessed independently by three reviewers using the DISCERN tool. The same plain text files collected were inputted into ChatGPT to determine whether they produced comparable metrics for readability and quality.
Results
The study results revealed a notable disparity between ChatGPT's readability assessment and that obtained from a reliable tool,
Readable.com
(p<0.05). This indicates a lack of alignment between ChatGPT's algorithm and that of established tools, such as
Readable.com
. Similarly, the DISCERN score generated by ChatGPT differed significantly from the scores generated manually by human evaluators (p<0.05), suggesting that ChatGPT may not be capable of accurately identifying poor-quality information sources regarding shock wave therapy as a treatment for erectile dysfunction.
Conclusion
ChatGPT’s evaluation of the quality and readability of online text regarding shockwave therapy for erectile dysfunction differs from that of human raters and trusted tools. Therefore, ChatGPT's current capabilities were not sufficient for reliably assessing the quality and readability of textual content. Further research is needed to elucidate the role of AI in the objective evaluation of online medical content in other fields. Continued development in AI and incorporation of tools such as DISCERN into AI software may enhance the way patients navigate the web in search of high-quality medical content in the future.
