A π-phase-shifted fiber Bragg grating fabricated using a single phase mask

, 2009
A fiber Bragg grating at twice the Bragg wavelength was fabricated by a standard phase mask technique and its two peaks/dips are attributed to the interleaved refractive index modulations along the fiber core that produced a pi-phase-shifted ...

Synergistic perspectives—How single‐molecule biophysics complement biochemical understanding

FEBS Letters, EarlyView.
In this review, we discuss how ensemble biochemistry and single‐molecule approaches are complementary, outline commonly used single‐molecule techniques, and illustrate their relevance through two representative case studies: chromatin organization by SMC complexes and pathway choice during DNA double‐strand break repair.

Design and Application of Phase-Only Diffractive Optical Element Based on Non-Iterative Method

Photonics, 2022
In this study, we devised a method for the design of continuous phase-only holographic masks that map laser light to arbitrary target illumination patterns, which have a wide range of applications.

Fabrication of a π-phase-shifted fiber Bragg grating at twice the Bragg wavelength with the standard phase mask technique

, 2009
A pair of reflection peaks/transmission dips, at twice the Bragg wavelength, were observed in spectra of a Type I fiber Bragg grating written with the standard phase mask technique. The occurrence of two peaks/ dips, rather than one, is attributed to the

Functional comparison of EncB and EncC cargo proteins in iron storage within the Myxococcus xanthus encapsulin

FEBS Letters, EarlyView.
Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

Inverse design for phase mask lithography

Optics Express, 2008
We have developed a method for designing the diffractive optics used in phase mask lithography. Genetic algorithms were used to inverse-design a grating's relief profile and associated exposure conditions so that desired periodic structures are formed. An experimentally promising grating designed to produce helices is demonstrated.

Metastatic niche shaped by host factors influences disseminated cancer cell fate

FEBS Letters, EarlyView.
Metastasis is shaped not only by cancer cells but also by the environments they encounter. This review explores how factors such as aging, diet, the microbiome, lifestyle, and environmental exposures remodel organ‐specific niches in the lung, liver, bone, and brain, influencing where metastatic cells survive, remain dormant, or grow, and ultimately ...

Beyond the IFTA – Phase mask generation for 3D laser beam shaping, tailored temperature distributions and optical amplifiers

Journal of the European Optical Society-Rapid Publications
The iterative Fourier transform algorithm (IFTA) is the most widely used algorithm for the generation of phase masks for laser beam shaping in the field of laser material processing. But its simplicity and efficiency also come with heavy limitations.

Moving fibre/phase mask-scanning beam technique for enhanced flexibility in producing fibre gratings with a uniform phase mask

, 1995
We demonstrate a new and flexible technique for producing photorefractive fibre gratings with a uniform phase mask. By slowly moving the fibre relative to the mask as the writing beam is scanned, wavelength shifts, pure apodisation and phase-shifted ...

Stimulator of interferon genes agonist augmented antitumor immunity of osimertinib in Egfr‐mutated lung cancer

Molecular Oncology, EarlyView.
Combining osimertinib with the STING agonist ADU‐S100 activates innate and adaptive immunity to overcome the non‐inflamed microenvironment of Egfr‐mutant lung cancer. This combination increases NK and CD8+ T‐cell infiltration, associated with activation of the STING‐IRF3 pathway and local immunogenic cell death.
