Trapped-Mode Resonances in Planar Metamaterials with High Structural Symmetry

, 2008
We propose a new type of planar metamaterials that can support high-Q electromagnetic modes, namely trapped modes, excitation of which is polarization ...

Single and Double Layer Planar Multiband PIFAs [PDF]

, 2006
A compact multiband planar inverted-F antenna (PIFA) suitable for distributed radio-over-fiber repeater networks is modified into a planar structure. It is shown that the planar antenna performance is not degraded with respect to the original PIFA and ...

A new flow chip in combination with multiphoton microscopy as a protocol for longitudinal 3D imaging of tissue calcification under shear stress

FEBS Open Bio, EarlyView.
Miniaturized flow chip platform enabling continuous perfusion and longitudinal multiphoton 3D imaging of vascular smooth muscle cell constructs under physiological flow. Brightfield imaging guides region selection, while CellTracker Green and mRuby‐labeled fetuin‐A visualize cells and mineral deposition, respectively. Magnesium supplementation markedly

Ionomycin suppresses cancer cell growth by disrupting mitochondrial transcription

FEBS Open Bio, EarlyView.
In this study, we identify a new function for the selective Ca2+ ionophore, ionomycin, as an inhibitor of mitochondrial transcription. Both total and nascent RNA analyses revealed that ionomycin treatment reduces the transcription of mitochondrial genes.

Single camera three component planar velocity measurements using two-frequency planar Doppler velocimetry (2ν-PDV) (2012) [PDF]

, 2006
Two-frequency planar Doppler velocimetry (2ν-PDV) is used in conjunction with imaging fibre bundles to make time-averaged three component velocity measurements using a single CCD camera and iodine cell. In this scheme the flow is sequentially illuminated

Thin-layer chromatography of sugars in plant material

Current Issues in Pharmacy and Medical Sciences, 2009
In the present publication experiments were concentrated on elaborating a simple method of separation standards of monosaccharides and choosing the best practically applied method of derivation. Sugars and their alcohol derivatives were analyzed.

Extension of Paul Erdős graph on hypergroups

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica
This paper introduces ultra non-commutative graphs derived from ultra non-commutative hypergroups. Vertices represent ultra non -commutative elements of the hypergroup U, defined as AU = {x ∈ U |Ǝy ∈ U, y ○ x ∩ x ○ y = ∅}. An edge connects vertices x and
