Spatiotemporal evolution of a cosine-modulated stationary field and Kerr frequency comb generation in a microresonator

, 2015
Based on the normalized spatiotemporal Lugiato-Lefever equation, the evolutions of cosine-modulated stationary fields relating to the generation of single-free spectral range (FSR) or multi-FSR Kerr frequency combs in a microresonator with anomalous ...

Single‐cell RNA sequencing of peripheral blood defines two immunological subtypes of Sjögren's disease distinguished by anti‐SSA antibodies and aberrant B cell populations

Arthritis &Rheumatology, Accepted Article.
Objectives Sjögren's disease (SjD) is a heterogeneous autoimmune disorder characterized by substantial clinical and molecular diversity. This heterogeneity raises key questions regarding the existence of distinct pathogenic mechanisms underlying disease subtypes.

Selective amplification of frequency comb modes via optical injection locking of a semiconductor laser: influence of adjacent unlocked comb modes

Optical injection locking can be used to isolate and amplify individual comb modes from an optical frequency comb (OFC). However, it has been observed that for narrow spaced OFCs (e.g.

Gabapentinoids‐duloxetine combination therapy for chronic pain: A mechanism oriented rational to bridge theoretical knowledge and real life setting

British Journal of Clinical Pharmacology, EarlyView.
Chronic pain represents a complex debilitating condition that extends beyond the protective function of physiological pain, often persisting as an independent disease entity. Chronic primary and secondary pain syndromes reflect a multifaceted continuum involving nociceptive, neuropathic and nociplastic mechanisms.
