TL;DR: The novel fabrication method of the polymer-free absorber and device parameters determined using nonlinear reflectivity measurement are described in detail and the observed operation bandwidth of approximately 1 microm is the broadest reported to date for a single carbon nanotube-based saturable absorber.
Abstract: Mode-locked sub-picosecond operation of Yb-, Er- and Tm:Hodoped fiber lasers operating at 1.05 microm, 1.56 microm and 1.99 microm, respectively, is demonstrated using the same sample carbon nanotube-based saturable absorber mirror. A mesh of single-walled carbon nanotubes was deposited on an Ag-mirror using a one-step dry-transfer contact press method to combine broadband saturable absorption and high reflectance properties. The novel fabrication method of the polymer-free absorber and device parameters determined using nonlinear reflectivity measurement are described in detail. To our knowledge the observed operation bandwidth of approximately 1 microm is the broadest reported to date for a single carbon nanotube-based saturable absorber.

TL;DR: It is shown that vibrotactile stimuli, applied on the palm and fingers of a congenitally deaf adult, activated his auditory cortices and recorded magnetoencephalographic signals indicated that the auditory Cortices were able to discriminate between the applied 180 Hz and 250 Hz vibration frequencies.

TL;DR: In this article, the authors propose an interactive process of preference programming which allows the decision maker to enter ambiguous preference statements by indicating the relative importance of factors as intervals of values on a ratio scale, and synthesize the interval judgments into dominance relations on the alternatives by solving a series of linear programming problems.

TL;DR: This study employs atomistic simulations and experiments to characterize a cholesterol compound with fluorescent boron dipyrromethene difluoride linked to sterol carbon‐24 (BODIPY‐cholesterol), and concludes that this new probe closely mimics the membrane partitioning and trafficking of cholesterol and enables the direct monitoring of sterol movement by time‐lapse imaging using trace amounts of the probe.
Abstract: Analysis of sterol distribution and transport in living cells has been hampered by the lack of bright, photostable fluorescent sterol derivatives that closely resemble cholesterol. In this study, we employed atomistic simulations and experiments to characterize a cholesterol compound with fluorescent boron dipyrromethene difluoride linked to sterol carbon-24 (BODIPY-cholesterol). This probe packed in the membrane and behaved similarly to cholesterol both in normal and in cholesterol-storage disease cells and with trace amounts allowed the visualization of sterol movement in living systems. Upon injection into the yolk sac, BODIPY-cholesterol did not disturb zebrafish development and was targeted to sterol-enriched brain regions in live fish. We conclude that this new probe closely mimics the membrane partitioning and trafficking of cholesterol and, because of its excellent fluorescent properties, enables the direct monitoring of sterol movement by time-lapse imaging using trace amounts of the probe. This is, to our knowledge, the first cholesterol probe that fulfills these prerequisites.
