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 ...

Exit-Site Infection: A Comparison of Classification Systems.

In general, in peritoneal dialysis (PD) practice in hospitals, Twardowski and Prowant's exit-site classification system is used, while the International Society for Peritoneal Dialysis (ISPD) exit-site scoring system is practical to use in community visits with less experienced healthcare personnel. Nevertheless, when exit-site scoring is 3 points under the ISPD exit-site score system and it falls in the category of equivocal under the Twardowski and Prowant's exit-site classification, the physician should ...

Gunshot Suicide: Cherry-Red Discoloration of the Temporal Muscle Beneath the Exit Wound.

The article describes a case of gunshot suicide to the head in a 51-year-old man. The entrance wound was located in the left temple and exit wound in the right temple. The entrance wound had the characteristics of a hard-contact gunshot wound. The most interesting finding in this case was cherry-red discoloration of the right temporal muscle surrounding the exit wound. This finding could make the determination of the entrance versus exit gunshot wound challenging, especially if the wounds are of atypical ap...

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...

Nurses who work rotating shifts consume more energy, macronutrients and calcium when they work the night shift versus day shift.

Shift work has been associated with increased body mass index (BMI), metabolic disruption and increased chronic disease risk. Typically, these reports compare individuals who work the day shift to those who work the night shift. Because shift assignment is not random, differences may reflect other, unmeasured characteristics that account for outcome differences.

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...

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...

Food policy in the era of Trump - limits to deregulation.

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...

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.

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...

Work and family conflict in relation to work exit in later career stage: a 20 years follow-up of Whitehall II study.

This study investigated relationships between work-family conflict and routes of later work exit.

Multimodal general anesthesia approach for Ex Utero Intrapartum Therapy (EXIT) procedures: two case reports.

High-dose volatile anesthesia is the most common method of achieving uterine relaxation for Ex Utero Intrapartum Therapy (EXIT) procedures. Other methods employ nitroglycerin for additional uterine relaxation with or without remifentanil for additional fetal analgesia. We report a combination approach including one minimum alveolar concentration of volatile anesthetic plus nitroglycerin and remifentanil infusions, to provide timely uterine relaxation under general anesthesia for both mother and fetus, durin...

Progress and Challenges in Sexual Orientation and Gender Identity Measurement in the First Year of the Trump Administration.

Methyl dihydrojasmonate and lilial are the constituents with an "off-label" insect repellence in perfumes.

Insect repellents are widely used to fend off nuisance mosquitoes and, more importantly, to reduce or eliminate mosquito bites in areas where viruses and other vector-borne diseases are circulating. Synthesized more than six decades ago, DEET is the most widely used insect repellent. Plant-derived compounds are used in a plethora of commercial formulations and natural recipes to repel mosquitoes. They are also used as fragrances. We analysed Bombshell® to identify the constituent(s) eliciting a previously ...

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...

Observation of a Goos-Hänchen-like Phase Shift for Magnetostatic Spin Waves.

In optics, a light beam experiences a spatial shift in the beam plane upon total internal reflection. This shift is usually referred to as the Goos-Hänchen shift. When dealing with plane waves, it manifests itself as a phase shift between an incoming and reflected wave that depends on the wave vector component along the interface. In the experiments presented here, plane spin waves are excited in a 60-nm-thick Permalloy film and propagate towards the edge of the film. By means of time-resolved scanning Ker...

Night shift work exposure profile and obesity: Baseline results from a Chinese night shift worker cohort.

Raman-assisted phase sensitive amplifier using a fiber Bragg grating-based tunable phase shifter.

A low-loss Raman-assisted phase sensitive amplifier (PSA) with a ∼20  dB signal net gain is experimentally demonstrated. The amplitude and phase adjustment for PSA are achieved by using non-uniform Raman gain and a tunable fiber Bragg grating (FBG), respectively. The total component loss of the system is measured to be ∼8  dB. By tuning the FBG central wavelength, (1) an up to 5.6 dB signal gain improvement is obtained; and (2) a ∼4  dB receiver sensitivity enhancement is observed for 2...

Self-sustaining Positive Feedback Loops in Discrete and Continuous Systems.

We consider a dynamic framework frequently used to model gene regulatory and signal transduction networks: monotonic ODEs that are composed of Hill functions. We derive conditions under which activity or inactivity in one system variable induces and sustains activity or inactivity in another. Cycles of such influences correspond to positive feedback loops that are self-sustaining and control-robust, in the sense that these feedback loops "trap" the system in a region of state space from which it cannot exit...
