Dipolar Filtered magic-sandwich-echoes as a tool for probing molecular motions using time domain NMR [PDF]

open access: yes, 2017
We present a simple $^1$H NMR approach for characterizing intermediate to fast regime molecular motions using $^1$H time-domain NMR at low magnetic field. The method is based on a Goldmann Shen dipolar filter (DF) followed by a Mixed Magic Sandwich Echo (MSE).

Data Transformations and Goodness-of-Fit Tests for Type-II Right Censored Samples [PDF]

open access: yesarXiv, 2013
We suggest several goodness-of-fit methods which are appropriate with Type-II right censored data. Our strategy is to transform the original observations from a censored sample into an approximately i.i.d. sample of normal variates and then perform a standard goodness-of-fit test for normality on the transformed observations.

Pairing evidence of 8CB molecules adsorbed on MoS2: Influence of 2D commensurability on the intralamellar structure [PDF]

open access: yesarXiv, 2000
By combining X-ray diffraction studies under grazing incidence (GIXD) and Scanning Tunneling Microscopy (STM) measurements, we have precisely determined the structure of 8CB molecules adsorbed on MoS2, under the thick organic film. The commensurability of the adsorbed network and the intracell structure have been determined, revealing a complex ...

Melatonin decreases eye pressure in depressive patients with normal intraocular pressure

open access: yesArchives of Clinical and Experimental Surgery, 2019
Background/Aim: In this study, we aimed to show the effect of melatonin, a pineal hormone, on intraocular pressure in patients with depression and normal ocular tension.

On the Validity of the Imbert-Fick Law: Mathematical Modelling of Eye Pressure Measurement [PDF]

open access: yes, 2016
YesOphthalmologists rely on a device known as the Goldmann applanation tonometer to make intraocular pressure (IOP) measurements. It measures the force required to press a flat disc against the cornea to produce a flattened circular region of known ...

Development and validation of a correction equation for Corvis tonometry. [PDF]

open access: yes, 2015
Primary objectiveThis study uses numerical analysis and validation against clinical data to develop a method to correct intraocular pressure (IOP) measurements obtained using the Corvis Tonometer for the effects of central corneal thickness (CCT), and ...

A novel approach to the synthesis of nanostructured metal-organic films: X-ray radiolysis of silver ions using a Langmuir monolayer as a template [PDF]

open access: yesarXiv, 2003
An application of the radiolysis method using X-ray synchrotron beam is developed as a novel approach to the synthesis of metal-organic films with controlled shapes and thickness. We demonstrate that a Langmuir monolayer deposited onto a silver ion-containing subphase, irradiated by an incident beam impinging below the critical angle for total ...
