Study of contaminated snow cover using remote sensing in the Eastern Himalayas of Arunachal Pradesh, India.

Snow is considered contaminated when any foreign materials are deposited/mixed with it, which can accelerate melting and significantly impact the snow cover's radiative balance. Such an enhanced melting rate results in a reduction in freshwater sources at the catchment level. In optical remote sensing, snow contamination is widely studied using a normalizing difference index called the snow contamination index.

Experimental investigation of circumnutation-inspired penetration in sand.

Probes that penetrate soil are used in fields such as geotechnical engineering, agriculture, and ecology to classify soils and characterize their properties. Conventional tools such as the Cone Penetration Test (CPT) often face challenges due to the lack of reaction force needed to penetrate stiff or dense soil layers, necessitating the use of large drill rigs. This paper investigates more efficient means of penetrating soil by taking inspiration from a plant-root motion known as circumnutation.

Simplistic metasurface design approach for incident angle and polarization insensitive rcs reduction.

This paper proposes the design of a metasurface for polarization and incident angle-insensitive RCS reduction applications. An ellipse-shaped unit cell is utilized as a polarization converter, which is then arranged to form a checkerboard surface. While a single layer checkerboard structure gives a wideband RCS reduction, a double layer structure yields polarization and incident angle independent operation.

Cardiac autonomic dysfunctions in type 2 diabetes mellitus: an investigative study with heart rate variability measures.

Cardiac autonomic neuropathy (CAN) is a common yet underdiagnosed complication of Type 2 diabetes mellitus (T2DM). Heart rate variability (HRV), a sensitive diagnostic marker of cardiovascular risk, could help detect CAN at its earliest stage. However, the progression of CAN based on age and disease duration in T2DM is lacking.

Maresins: The Mainstay in Periodontal Resolution.

Not much was known about the resolution of inflammation until the recent past when significant breakthroughs led to the unveiling of the exact mechanism of this. It is now known that the resolution of inflammation involves specific mediators of resolution such as lipoxins, protectins, resolvins, and maresins, making it an active process. Of these mediators, maresins are the latest discovery.
