Given the number of different agencies and the complexity of institutional and professional relationships in the production, management and regulation of the built environment, many …

Cannabinoid CB1 Receptors Mediate the Gastroprotective Effect of Neurotensin.

Iranian journal of basic medical sciences

Hassanzadeh P, Arbabi E.
PMID: 23492756
Iran J Basic Med Sci. 2012 May;15(3):803-10.

OBJECTIVES: Several lines of evidence indicate that neuropeptides exhibit protective properties against gastroduodenal ulcers. Neurotensin, a gut-brain neuropeptide, is implicated in a number of physiological processes in the central nervous system and peripheral tissues including gastrointestinal tract. In the...

Role of Oxidative Stress on Vaginal Bleeding during The First Trimester of Pregnant Women.

International journal of fertility & sterility

Deveer R, Deveer M, Engin-Üstün Y, Akbaba E, Uysal S, Sarikaya E, Gülerman C, Mollamahmutoglu L.
PMID: 24520496
Int J Fertil Steril. 2014 Jan;7(4):271-4. Epub 2013 Dec 22.

BACKGROUND: Reactive oxygen species (ROS) are produced in many metabolic and physiologic processes. Antioxidative mechanisms remove these harmful species. Our aim was to assess whether serum total antioxidant capacity and total oxidant status altered during first trimester pregnancies with...

The Effects of Progesterone on Glial Cell Line-derived Neurotrophic Factor Secretion from C6 Glioma Cells.

Iranian journal of basic medical sciences

Hassanzadeh P, Arbabi E.
PMID: 23493386
Iran J Basic Med Sci. 2012 Sep;15(5):1046-52.

OBJECTIVES: Progesterone is a steroid hormone whose biology has been greatly studied within the confines of reproductive function. In recent years, the neuroprotective effects of progesterone have attracted growing interest. Glial cell line-derived neurotrophic factor (GDNF), is a neurotrophic...

Discovering Central Practitioners in a Medical Discussion Forum Using Semantic Web Analytics.

Studies in health technology and informatics

Rajabi E, Abidi SSR.
PMID: 28423840
Stud Health Technol Inform. 2017;235:486-490.

The aim of this paper is to investigate semantic web based methods to enrich and transform a medical discussion forum in order to perform semantics-driven social network analysis. We use the centrality measures as well as semantic similarity metrics...

Visible Wavelength Color Filters Using Dielectric Subwavelength Gratings for Backside-Illuminated CMOS Image Sensor Technologies.

Nano letters

Horie Y, Han S, Lee JY, Kim J, Kim Y, Arbabi A, Shin C, Shi L, Arbabi E, Kamali SM, Lee HS, Hwang S, Faraon A.
PMID: 28388090
Nano Lett. 2017 May 10;17(5):3159-3164. doi: 10.1021/acs.nanolett.7b00636. Epub 2017 Apr 13.

We report transmissive color filters based on subwavelength dielectric gratings that can replace conventional dye-based color filters used in backside-illuminated CMOS image sensor (BSI CIS) technologies. The filters are patterned in an 80 nm-thick poly silicon film on a...

Sublinear scaling for time-dependent stochastic density functional theory.

The Journal of chemical physics

Gao Y, Neuhauser D, Baer R, Rabani E.
PMID: 25612688
J Chem Phys. 2015 Jan 21;142(3):034106. doi: 10.1063/1.4905568.

A stochastic approach to time-dependent density functional theory is developed for computing the absorption cross section and the random phase approximation (RPA) correlation energy. The core idea of the approach involves time-propagation of a small set of stochastic orbitals...

Optimal metal domain size for photocatalysis with hybrid semiconductor-metal nanorods.

Nature communications

Ben-Shahar Y, Scotognella F, Kriegel I, Moretti L, Cerullo G, Rabani E, Banin U.
PMID: 26783194
Nat Commun. 2016 Jan 19;7:10413. doi: 10.1038/ncomms10413.

Semiconductor-metal hybrid nanostructures offer a highly controllable platform for light-induced charge separation, with direct relevance for their implementation in photocatalysis. Advances in the synthesis allow for control over the size, shape and morphology, providing tunability of the optical and...

Fundamental limits of ultrathin metasurfaces.

Scientific reports

Arbabi A, Faraon A.
PMID: 28262739
Sci Rep. 2017 Mar 06;7:43722. doi: 10.1038/srep43722.

We present a set of universal relations which relate the local transmission, reflection, and polarization conversion coefficients of a general class of non-magnetic passive ultrathin metasurfaces. We show that these relations are a result of equal forward and backward...

MEMS-tunable dielectric metasurface lens.

Nature communications

Arbabi E, Arbabi A, Kamali SM, Horie Y, Faraji-Dana M, Faraon A.
PMID: 29476147
Nat Commun. 2018 Feb 23;9(1):812. doi: 10.1038/s41467-018-03155-6.

Varifocal lenses, conventionally implemented by changing the axial distance between multiple optical elements, have a wide range of applications in imaging and optical beam scanning. The use of conventional bulky refractive elements makes these varifocal lenses large, slow, and...

Effect of Thermal Fluctuations on the Radiative Rate in Core/Shell Quantum Dots.

Nano letters

Balan AD, Eshet H, Olshansky JH, Lee YV, Rabani E, Alivisatos AP.
PMID: 28183177
Nano Lett. 2017 Mar 08;17(3):1629-1636. doi: 10.1021/acs.nanolett.6b04816. Epub 2017 Feb 14.

The effect of lattice fluctuations and electronic excitations on the radiative rate is demonstrated in CdSe/CdS core/shell spherical quantum dots (QDs). Using a combination of time-resolved photoluminescence spectroscopy and atomistic simulations, we show that lattice fluctuations can change the...
