A 31 L multilevel inverter topology with less switching devices for hybrid electric vehicle applications.

In this article, a 12 switch 31 L multi-level inverter (MLI) is proposed with the benefits of least switching devices for electric vehicle applications. In most electric vehicles (EV), conventional inverters are utilized so the lifetime of electric vehicle induction motors is reduced due to the high THD level and high voltage stress. To rectify this, a new inverter topology is proposed with minimum switching devices by increasing the level to 31, and also the THD should be maintained within IEEE standards.

Artificial intelligence: Potential tool to subside SARS-CoV-2 pandemic.

Artificial intelligence (AI), a method of simulating the human brain in order to complete tasks in a more effective manner, has had numerous implementations in fields from manufacturing sectors to digital electronics. Despite the potential of AI, it may be obstinate to assume that the person administered society would rely solely on AI; with an example being the healthcare field. With the ever-expanding discoveries made on a regular basis regarding the growth of various diseases and its preservations, utilizing brain power may be deemed essential, but that doesn't leave AI as a redundant asset.

Perspectives and Consensus among International Orthopaedic Surgeons during Initial and Mid-lockdown Phases of Coronavirus Disease.

With a lot of uncertainty, unclear, and frequently changing management protocols, COVID-19 has significantly impacted the orthopaedic surgical practice during this pandemic crisis. Surgeons around the world needed closed introspection, contemplation, and prospective consensual recommendations for safe surgical practice and prevention of viral contamination. One hundred orthopaedic surgeons from 50 countries were sent a Google online form with a questionnaire explicating protocols for admission, surgeries, discharge, follow-up, relevant information affecting their surgical practices, difficulties faced, and many more important issues that happened during and after the lockdown.

Computational and Microstructural Stability Analysis of Shock Wave Interaction with NbB-BC-Based Nanostructured Ceramics.

Despite extensive research on developing different transition metal boride composites for aero-thermostructural applications, the understanding of the shockwave interaction using high pressure shock testing facilities and computational simulation of such interactions are much less explored. This aspect is even more important for much less explored ceramics, like NbB-based materials. While addressing this aspect, the present investigation reports the thermostructural stability of spark plasma sintered NbB-(0-40) mol % BC composites under the hypersonic aero-thermodynamic conditions using a miniature detonation-driven shock tube facility.

Children (10-12 years age) of women with epilepsy have lower intelligence, attention and memory: Observations from a prospective cohort case control study.

Objective: To compare the cognitive outcome of children of women with epilepsy (CWE) with matched controls (CWO).

Methods: CWE (10-12 years) under follow up in Kerala Registry of Epilepsy and Pregnancy (n=190) were evaluated with WISC-IV, Trail Making Test (TMT), Rey Auditory Verbal Learning Test (RAVLT) and compared with age and sex matched children of women without epilepsy - CWO (n=149) drawn from schools in the same region. The dosage was expressed as prescribed daily dose/daily-defined dose (PDD/DDD) ratio in order to make comparisons.
