On stability of distance under some tensor products and some calculations
We prove that the Kadison-Kastler and Christensen distances are stable under the Banach space injective tensor product (resp., the Banach space projective tensor product) of a Banach space with any unital commutative $C^*$-algebra (resp., of a $C^*$-algebra with any unital $C^*$-algebra). Apart…

Quantification of Dysautonomia in Major Depressive Disorder Using the Composite Autonomic Scoring Scale-31 (COMPASS-31)
Background Dysautonomia denotes an alteration in the autonomic nervous system that can significantly lead to multiorgan failure. Conversely, depression not only affects cognitive functions but also poses a risk factor for sudden cardiac death. In our study, the Composite Autonomic Scoring-31…

Artificial Intelligence-Enabled Smartwatch Used for the Detection of Idiopathic Ventricular Tachycardia: A Case Report
Cardiovascular disease has become a huge burden to human health. Artificial intelligence (AI)-enabled smartwatches continuously monitor the heart rate, which potentially helps to diagnose unwarranted rhythm and irregularity problems such as tachycardia, bradycardia, and fibrillation. Deep learning…

Dysautonomia in ‘long COVID’: Case report
BACKGROUND: The reason for autonomic dysfunction in COVID-19 is yet to get clear, though we tend to notice a few dysautonomia cases during post-COVID-19 manifested most commonly in the form of postural orthostatic tachycardia syndrome (POTS). CASE PRESENTATION: A case of autonomic dysregulation is…

Bridging Cardiac and Mental Health: Screening for Depression in Cardiology Settings
Depression is a highly prevalent comorbidity in patients with cardiovascular disease (CVD), affecting approximately one in five cardiac patients and contributing to adverse cardiovascular outcomes, increased mortality, and reduced quality of life. Despite clinical guidelines from the American Heart…

Predicting rice diseases across diverse agro-meteorological conditions using an artificial intelligence approach
With the aid of a plant disease forecasting model, the emergence of plant diseases in a given region can be predicted ahead of time. This makes it easier to take proactive steps to reduce losses before they occur. The proposed model attempts to find an association between agrometeorological…
