PURPOSE A novel quantitative magnetic resonance imaging (MRI) method, namely, temporal diffusion spectroscopy (TDS), was used to detect the response of tumor cells (notably, mitotic arrest) to a specific antimitotic treatment (Nab-paclitaxel) in culture and human ovarian xenografts and evaluated as an early imaging biomarker of tumor responsiveness. METHODS TDS measures a series of apparent d...

Perspectives reignites the issue of the role that phthalate exposure during pregnancy may play in the etiology of reproductive disorders in human males. It does so by providing the first evidence of an association between phthalate exposure of mothers during pregnancy and attenuation of androgen action in their male babies. If this association is indicative of cause and effect, it will join tog...

The energetics of topological defects (TDs) in carbon nanotubes (CNTs) and their kinetic healing during the catalytic growth are explored theoretically. Our study indicates that, with the assistance of a metal catalyst, TDs formed during the addition of C atoms can be efficiently healed at the CNT-catalyst interface. Theoretically, a TD-free CNT wall with 10(8)-10(11) carbon atoms is achievable...

The two main hindrances for a wider application of the model checking approach for verification of concurrent and distributed systems are the state explosion problem and its limitation in handling infinite state systems. We consider a class of infinite state systems given by certain types of Transition Diagrams (TDs), called simple TDs, that employ commutative functions for updating variables. ...

We propose a joint discrete stochastic optimization based transmit diversity selection (TDS) and relay selection (RS) algorithm for decode-and-forward (DF), cooperative MIMO systems with a non-negligible direct path. TDS and RS are performed jointly with continuous least squares channel estimation (CE), linear minimum mean square error (MMSE) receivers are used at all nodes and no inter-relay c...

Terahertz (THz) time-domain spectroscopy (TDS) imaging is considered a nondestructive evaluation method for composite materials used for examining various defects of carbon fiber reinforced polymer (CFRP) composites and fire-retardant coatings in the reflective imaging modality. We demonstrate that hidden defects simulated by Teflon artificial inserts are imaged clearly in the perpendicular pol...

This letter describes the use of THz time-domain spectroscopy (TDS) applied in transmission to the secondary explosive 1,3,5 trinitro-s-triazine. Samples were also subjected to Fourier transform infrared spectroscopy over the same range for comparison. A detailed spectroscopy study is presented. General agreement between results from both methods confirms the absorption features found. A compar...

Materials and methods: Performance and nutrient digestibility were determined for pigs consuming either water treated by reverse osmosis (RO; 219 mg total dissolved solutes (TDS) per L, 29 mg sulfates per L) or untreated ground water (3078 mg TDS per L, 1650 mg sulfates per L). In each of two experiments, approximately 240 pigs (20 ± 3 days of age, 5.9 ± 1.0 kg) received either RO-treated or un...

تهدف الورقة بصورة أساسية إلى التعرف على السياسات التي يمارسها الاتحاد الأوروبي تجاه دول المغرب العربي قبل وبعد ثورات الربيع لفترة زمنية محددة. من خلال هذه البحثية، سوف يتضح كيفية تدخل في البلدان، وهل يعد سلبياُ أو إيجابياً طرح قضايا الهجرة والإرهاب، والطاقة، والديمقراطية لبلدان محل الدراسة الثورات. المقارنات المستنتجة يتم تحليلها بطريقة تمحيصية، ومعرفة أسباب الاختلاف. هذا الصدد وكما سيتضح لاحقًا أ...
