Effects of Measurement Center Shift on Ganglion Cell-inner Plexiform Layer Thickness Measurements.

Our authors studied the effects of measurement center shift on ganglion cell-inner plexiform layer (GCIPL) thickness measurements in Cirrus spectral-domain optical coherence tomography (SD-OCT). The measurement center shift affects the GCIPL thickness measurement depending on the distance of shift.

FBG wavelength demodulation based on a radio frequency optical true time delay method.

A new fiber Bragg grating (FBG) wavelength shift demodulation method based on optical true time delay microwave phase detection is proposed. We used a microwave photonic link (MPL) to transport a radio frequency (RF) signal over a dispersion compensation fiber (DCF). The wavelength shift of the FBG will cause the time delay change of the optical carrier that propagates in an optical fiber with chromatic dispersion, which will result in the variation of the RF signal phase. A long DCF was adopted to enlarge ...

Trump and the GOP agenda: implications for retirement policy.

Policymakers need to act to protect Americans' retirement security. A significant portion of Americans are at risk of not being able to maintain their standard of living in retirement and research suggests that this percentage is likely to grow. This commentary provides background on the current state of American retirement, highlights recent efforts to reform retirement policy, and predicts what to expect under President Donald Trump. Retirement has not been a major focus of national policymakers in recent...

Cbl Ubiquitin Ligases Control B Cell Exit from the Germinal-Center Reaction.

Selective expansion of high-affinity antigen-specific B cells in germinal centers (GCs) is a key event in antibody affinity maturation. GC B cells with improved affinity can either continue affinity-driven selection or exit the GC to differentiate into plasma cells (PCs) or memory B cells. Here we found that deleting E3 ubiquitin ligases Cbl and Cbl-b (Cbls) in GC B cells resulted in the early exit of high-affinity antigen-specific B cells from the GC reaction and thus impaired clonal expansion. Cbls were h...

Draining the swamp while making America great: senior dissonance in the age of Trump.

In his surprise election as President, Donald Trump enjoyed disproportionate electoral support from older voters, many of whom saw in Trump a person who would work to reverse demographic, economic, and cultural forces that had transformed American life as they had long seen it. Yet, Trump's campaign and incumbency has also been very much about gutting the Washington policy establishment of officials, bureaucrats, and lobbyists (aka, the Swamp) which, for over half a century, has been instrumental in enactin...

Contrast-dependent red-green hue shift.

On bright surrounds, red-green-balanced yellow targets become greenish brown with decreased target luminance, and red-green-balanced brown targets become reddish yellow with increased target luminance. These effects imply luminance- and/or contrast-dependent weighting of M- and L-cone signals in post-receptoral pathways. We show psychophysically that luminance contrast between the surround and the target is the primary determinant of the magnitude of red-green hue shift, requiring surround luminance at leas...

Chemical shift imaging with in-phase and opposed-phase sequences at 3 T: what is the optimal threshold, measurement method, and diagnostic accuracy for characterizing marrow signal abnormalities?

To determine the threshold signal drop on 3-T chemical shift imaging (CSI), with in-phase (IP) and opposed-phase (OP) sequences, for accurately identifying bone marrow replacement with 100% sensitivity, and determine a clinically useful measurement method for deriving such a threshold.

Signal intensity influences on the atomic Faraday filter.

Previous studies of the Faraday anomalous dispersion optical filter (FADOF) mainly focus on the weak signal light filtering, without regard for the influences of the signal light intensity on the filter itself. However, in some applications the signal light is strong enough to change the filter's performance. In this work, the influences of the signal light intensity on the transmittance spectrum is experimentally investigated in a 780 nm Rb85 FADOF in both the line-center and wings operation modes. The re...

Undermining the ACA through the executive branch and federalism: what the Trump administration's approach to health reform means for older Americans.

The ACA has survived multiple existential threats in the legislative and judicial branches, including dozens of congressional attempts at repeal and two major Supreme Court cases. Even as it seems that the ACA is here to stay, what the law accomplishes is far from settled. The Trump administration is using executive powers to weaken the law, in many cases the same powers that President Obama used to strengthen the effects of the reform. States have responded by seeking flexibility to pursue reforms, such as...

Tunable 360° microwave photonic multichannel phase shifter with frequency quadrupling.

In this paper, a photonic scheme to generate a frequency-quadrupled microwave signal with full-range 360° tunable phase shift is proposed and experimentally demonstrated. Pure ±2nd-order sidebands with the carrier suppressed are generated by a dual-parallel Mach-Zehnder modulator. The two sidebands are separated by a fiber Bragg grating with the polarization state of one sideband rotated by 90 deg via a Faraday rotating mirror and then recombined to obtain a pair of orthogonally polarized wavelengths. Th...

Mid-life psychosocial work environment as a predictor of work exit by age 50.

To examine whether psychosocial work characteristics at age 45 years predict exit from the labour market by the age of 50 years in data from the 1958 British Birth Cohort.

Characterizing the effect of femtosecond photo-treatment on the center wavelength of fiber Bragg gratings.

Various types of pre- and post-treatments to optical fibers are typically used to improve and/or change the properties of fiber Bragg grating (FBG). Here, we investigate experimentally the effects of NIR femtosecond (fs) laser pulses used for pre- and post-treatment on the refractive index of the fiber, and the resulting center wavelength shift of an fs inscribed FBG. We observe "red"-shift when applying a suitable pre-treatment, and both "blue"- and "red"-shifts when applying post-treatment. We characteriz...

A method for rapid testing of social learning in vampire bats.

Designing experiments on social learning using an untested behaviour or species requires baseline knowledge of how the animals will perform. We conducted a pilot study of a procedure for rapidly testing social learning in the highly social common vampire bat () using a simple maze. To create demonstrators, we allowed captive bats to learn to exit a three-dimensional maze, which reunited them with their colony as a reward. We then filmed naive bats in the same maze, comparing their ability to exit the maze b...

Multifunctional all-optical signal processing scheme for wavelength-division-multiplexing multicast, wavelength conversion, format conversion, and all-optical encryption using hybrid modulation format exclusive-OR gates based on four-wave mixing in highly nonlinear fiber.

A multifunctional optical signal processing scheme for 10-Gbaud quadrature phase shift keying (QPSK) and binary phase shift keying (BPSK) signals based on four-wave mixing (FWM) in highly nonlinear fiber (HNLF) is proposed. Wavelength-division-multiplexing (WDM) multicast, wavelength conversion, modulation format conversion, and hybrid modulation format exclusive-OR (HMF-XOR) logic gates are realized simultaneously by simulation. One-to-three WDM multicast of 20-Gbps QPSK signals are achieved paying the opt...

Change from health center to family physician period in the Turkish health system: A qualitative study.

Health care reforms in Turkey have been implemented resolutely in the last 12 years. The shift from health center (HC) to a family physician (FP) approach is 1 of the basic interventions of these reforms. The goal of the current study is to evaluate opinions of patients, health care workers, and managers, using qualitative methods.

Pressure-induced photoluminescence of MgO.

It is reported in this paper that pressure can promote strong photoluminescence (PL) in MgO. The PL measurements of MgO powder indicate that it has no obvious luminescence at pressures lower than 13 GPa. PL starts to appear upon further compression and reaches a maximum intensity at about 35 GPa. The center of the emission band shows a red shift at lower pressures and turns to a blue shift as pressure exceeds 25 GPa. The PL is preserved upon complete decompression. The defects and micro-strain due to the pl...

Shift work, parental cardiovascular disease and myocardial infarction in males.

Shift work has been associated with an increased risk of cardiovascular disease (CVD). However, there is a need for more studies to determine whether there is an interaction between shift work and other risk factors of CVD, thereby increasing the risk of CVD in shift workers.

In utero Fetal Intubation for a Large Neck Mass: A Minimally Invasive EXIT Option.

Fetuses with obstructive neck and orofacial lesions have been delivered via an ex utero intrapartum treatment (EXIT) procedure to facilitate securement of the airway while on placental circulation. Pregnancy-related cardiovascular changes and technical issues unique to an EXIT procedure increase fetal and maternal risks relative to a standard cesarean section. In order to circumvent such issues, fetal endoscopic intubation has been proposed. We report a case of a fetus with a large neck mass (mixed solid an...

Using H amide temperature coefficients to define intrinsically disordered regions: An alternative NMR method.

This report describes a cost-effective experimental method for determining an intrinsically disordered protein (IDP) region in a given protein sample. In this area, the most popular (and conventional) means is using the amide ( H ) NMR signal chemical shift distributed in the range of 7.5-8.5 ppm. For this study, we applied an additional step: analysis of H chemical shift temperature coefficients ( H -CSTCs) of the signals. We measured H- N two-dimensional NMR spectra of model IDP samples and ordered samp...

The "mechanostat" principle in cell differentiation. The osteochondroprogenitor paradigm.

The "mechanostat" principle may be depicted as an oscillating signal of a signaling molecule, in which the amplitude, frequency, cumulative level, delay, and duration of the curve encode the information for concrete cellular responses and biological activities. When the oscillating signal is kept sustained (present delay), cell exit may be performed, whereas when the oscillating signal remains robust, cell proliferation may take place. B-catenin-Wnt signaling pathway has a key role in the differentiation of...

EXIT (ex utero intrapartum treatment) in a growth restricted fetus with tracheal atresia.

Congenital high airway obstruction syndrome (CHAOS) encompasses a heterogeneous group of pathologies leading to poor lung development and difficulty oxygenating the newborn after delivery. While previously uniformly fatal, the ex utero intrapartum therapy (EXIT) procedure has provided a method to treat these patients and provide an airway to potentiate survival. We present a patient diagnosed prenatally with CHAOS secondary to tracheal atresia complicated by severe intra-uterine growth restriction (IUGR) wh...

Data-driven gating in PET: Influence of respiratory signal noise on motion resolution.

Data-driven gating (DDG) approaches for positron emission tomography (PET) are interesting alternatives to conventional hardware-based gating methods. In DDG, the measured PET data themselves are utilized to calculate a respiratory signal that is subsequently used for gating purposes. The success of gating is then highly dependent on the statistical quality of the PET data. In this study we investigate how this quality determines signal noise and thus motion resolution in clinical PET scans using a center-o...

Direct measurement of the composite Goos-Hänchen shift of an optical beam.

We experimentally study the Goos-Hänchen shift of a focused Gaussian optical beam in the critical region of incidence. We directly measure the beam's shift evaluated from the displacement of the location of the beam's intensity peak and its centroid by a novel image analysis method. We verify that the evaluation method has a dramatic impact on the physics of beam shift phenomena. The influence of wavelength, beam waist, and propagation distance on the beam shift is studied. Our experimental results confirm...
