Entropic splitter for particle separation.

Physical review letters

Reguera D, Luque A, Burada PS, Schmid G, Rubí JM, Hänggi P.
PMID: 22324667
Phys Rev Lett. 2012 Jan 13;108(2):020604. doi: 10.1103/PhysRevLett.108.020604. Epub 2012 Jan 13.

We present a particle separation mechanism which induces the motion of particles of different sizes in opposite directions. The mechanism is based on the combined action of a driving force and an entropic rectification of the Brownian fluctuations caused...

Homozygosity for Non-H1069Q Missense Mutations in ATP7B Gene and Early Severe Liver Disease: Report of Two Families and a Meta-analysis.

JIMD reports

Usta J, Abu Daya H, Halawi H, Al-Shareef I, El-Rifai O, Malli AH, Sharara AI, Habib RH, Barada K.
PMID: 23430908
JIMD Rep. 2012;4:129-37. doi: 10.1007/8904_2011_91. Epub 2011 Nov 08.

Most patients with Wilson's disease (WD) are compound heterozygote, which complicates establishing genotype-phenotype correlations. We identified five patients who presented with early and/or severe hepatic disease who are homozygous for W939C missense mutation on exon 12 of ATP7B. We...

Dual-channel polarization holography: a technique for recording two complex amplitude components of a vector wave.

Optics letters

Barada D, Ochiai T, Fukuda T, Kawata S, Kuroda K, Yatagai T.
PMID: 23114352
Opt Lett. 2012 Nov 01;37(21):4528-30. doi: 10.1364/OL.37.004528.

In this Letter, the principle of polarization holography for recording an arbitrary vector wave on a thin polarization-sensitive recording medium is proposed. It is analytically shown that the complex amplitudes of p- and s-polarization components are simultaneously recorded and...

Fast calculation of computer-generated holograms based on 3-D Fourier spectrum for omnidirectional diffraction from a 3-D voxel-based object.

Optics express

Sando Y, Barada D, Yatagai T.
PMID: 23037219
Opt Express. 2012 Sep 10;20(19):20962-9. doi: 10.1364/OE.20.020962.

We have derived the basic spectral relation between a 3-D object and its 2-D diffracted wavefront by interpreting the diffraction calculation in the 3-D Fourier domain. Information on the 3-D object, which is inherent in the diffracted wavefront, becomes...

Estimator reduction and convergence of adaptive BEM.

Applied numerical mathematics : transactions of IMACS

Aurada M, Ferraz-Leite S, Praetorius D.
PMID: 23482248
Appl Numer Math. 2012 Jun;62(6):787-801. doi: 10.1016/j.apnum.2011.06.014.

A posteriori error estimation and related adaptive mesh-refining algorithms have themselves proven to be powerful tools in nowadays scientific computing. Contrary to adaptive finite element methods, convergence of adaptive boundary element schemes is, however, widely open. We propose a...

Simultaneous two-wavelength Doppler phase-shifting digital holography.

Applied optics

Barada D, Kiire T, Sugisaka J, Kawata S, Yatagai T.
PMID: 22193014
Appl Opt. 2011 Dec 01;50(34):H237-44. doi: 10.1364/AO.50.00H237.

This paper presents a method based on the use of an image sensor for obtaining the complex amplitudes of beams diffracted from an object at two different wavelengths. The complex amplitude for each wavelength is extracted by the Doppler...

Laser ion acceleration toward future ion beam cancer therapy - Numerical simulation study -.

Laser therapy

Kawata S, Izumiyama T, Nagashima T, Takano M, Barada D, Kong Q, Gu YJ, Wang PX, Ma YY, Wang WM.
PMID: 24155555
Laser Ther. 2013;22(2):103-14. doi: 10.3136/islsm.22.103. Epub 2013 Mar 31.

BACKGROUND: Ion beam has been used in cancer treatment, and has a unique preferable feature to deposit its main energy inside a human body so that cancer cell could be killed by the ion beam. However, conventional ion accelerator...

The Potential of Mobile Apps for Improving Asthma Self-Management: A Review of Publicly Available and Well-Adopted Asthma Apps.

JMIR mHealth and uHealth

Tinschert P, Jakob R, Barata F, Kramer JN, Kowatsch T.
PMID: 28768606
JMIR Mhealth Uhealth. 2017 Aug 02;5(8):e113. doi: 10.2196/mhealth.7177.

BACKGROUND: Effective disease self-management lowers asthma's burden of disease for both individual patients and health care systems. In principle, mobile health (mHealth) apps could enable effective asthma self-management interventions that improve a patient's quality of life while simultaneously reducing...

Retrograde Venous Bullet Embolization to the Hepatic Inferior Vena Cava Located with Intraoperative Transesophageal Echocardiography.

CASE (Philadelphia, Pa.)

Busada M, Maldonado Y, Zhang Q.
PMID: 30062311

The authors present a case in which a GSW to the chest led to a retrograde venous bullet embolization. The fragment originated in the right atrium and embolized to the hepatic IVC, which was located with intraoperative TEE.

Chemosensitivity of U251 Cells to the Co-treatment of D-Penicillamine and Copper: Possible Implications on Wilson Disease Patients.
