The deterministic proliferation of the orientation of hexagonally packed cylinders (HEX) from the twinned body-centered cubic (BCC) phase is investigated by synchrotron small-angle X-ray scattering (SAXS) and rheo-optical methods for di- and triblock copolymers of styrene and isoprene (SI and SIS). Repeated heating and cooling cycles starting from an initially aligned HEX produce a proliferation of cylinder orientations from successively twinned BCC states. The evolution of the orientation distr

A tumoral calcinosis is considered a rare disorder with a poorly understood etiology. This uncommon soft tissue calcification is characterized clinically by the presence of an irregular, painless, periarticular soft tissue calcifying mass. People from African decent are mainly affected with the disease, which typically occurs in the periarticular regions. We report a case of a middle aged woman who complained a left inguinal subcutaneous mass. The characteristic clinical features, radiological a

In recent years, fibrillar string-based wearable sensors have gained significant attention for their ability to detect mechanical and physiological stimuli, including tactility, temperature, humidity, and glucose levels. Stretchability, flexibility, and lightweight nature of the fibrillar strings make them ideal for integration into textiles and wearable devices. This review highlights recent advancements in the fabrication of fibrillar string sensors by using various spinning techniques, includ
