Exceptional points are spectral singularities of open systems, where several eigenvalues and eigenvectors coalesce.In photonics, they are associated to remarkable phenomena, such as unidirectional scattering, enhanced sensing or chiral mode conversion.In this work, we study scattering of electromagnetic waves by a single dielectric nanoparticle and
Back and neck pain are commonly associated with intervertebral disc (IVD) degeneration.Structural augmentation of diseased nucleus pulposus (NP) tissue with biomaterials could restore degeneration-related IVD height loss and degraded biomechanical behaviors; however, effective NP replacement biomaterials are not commercially available.This study de
Abstract Background The World Health Organization (WHO) recommends that the cost effectiveness of introducing human papillomavirus (HPV) vaccination is considered before such a strategy is implemented.However, developing countries often lack the technical capacity to perform and interpret results of economic appraisals of vaccines.To provide inform
Autoimmune hepatitis is a chronic liver inflammation resulting from deregulation of immune tolerance mechanisms.Multiple sclerosis is also an inflammatory disease in ice blue graphic tee which the insulating covers of nerve cells in the brain and spinal cord are damaged.Here we present a case of an 18 year old female with multiple sclerosis was tre
