Enhanced photoinduced birefringence in methyl orange/polyvinyl alcohol composite film
四川大学学报. 自然科学版The influence of ambient humidity on the photoinduced birefringence of methyl orange doped polyvinyl alcohol （MO/PVA） composite film is investigated in this paper.We prepared MO/PVA films with three mass fractions （1%， 2% and 3%） and measured their ...

AA Amyloidosis Resulting From Unintended Discontinuation of Rheumatoid Arthritis Therapy due to Cognitive Impairment. [PDF]
Clin Case RepABSTRACT Amyloid A (AA) amyloidosis is a serious complication of chronic inflammatory diseases, including rheumatoid arthritis (RA). A 78‐year‐old woman with advanced dementia developed progressive renal dysfunction following prolonged, unintentional RA treatment discontinuation.

Limnology and Oceanography: Methods, EarlyView.Abstract Accurate direct measurements of coccolithophore particulate inorganic and organic carbon ratios (PIC/POC) are crucial for understanding the physiology and role these microbes play in global ocean carbon flux. Direct measurements of POC are commonly obtained by acid fuming or applying acid directly to filters to dissolve PIC (CaCO3) prior to CN

Fiber Birefringence Modeling for Polarization Mode Dispersion [PDF]
, 2007 This thesis concerns polarization mode dispersion (PMD) in optical fiber communications. Specifically, we study fiber birefringence, PMD stochastic properties, PMD mitigation and the interaction of fiber birefringence and fiber nonlinearity.

Ultra Short Pulse Laser Welding of Glass to Metal in the Low Fluence Regime
Laser &Photonics Reviews, EarlyView.Ultrashortpulse laser welding enables precise joining of glass and metal with minimal thermal damage. We introduce the TwoThresholds Criteria to identify suitable laser parameters by combining the nonlinearabsorption threshold in glass with the metalmodification fluence threshold.

Birefringence in single-mode optical fibres
, 1982 The birefringence properties of single-mode optical-fibre waveguides are discussed.A fibre birefringence measurement system has been developed specifically to measure the birefringence of fibres as a function of temperature, wavelength, twist and bending.

Frontiers of Bright CEP‐Stable Broadband Infrared Sources
Laser &Photonics Reviews, EarlyView.Bright CEP‐stable broadband infrared sources push the limits of ultrafast science by delivering exceptional brightness alongside few‐cycle durations and multi‐octave spectral coverage. This review highlights emerging architectures and nonlinear conversion strategies that scale power while preserving phase stability.

Low‐Hysteresis Cellulose‐Based Hydrogels for Strain Detecting
Macromolecular Rapid Communications, EarlyView.Low‐hysteresis hydrogel with high cellulose content is prepared. The modified cellulose is prepared through a sequential periodate oxidation and borohydride reduction process. The hydrogel can be used as a strain sensor with a gauge factor of 1.1 in the 0%–300% sensing range.
