Does angiotensin-1 converting enzyme genotype influence motor or cognitive development after pre-term birth?
No full textAbstract Background Raised activity of the renin-angiotensin system (RAS) may both amplify inflammatory and free radical responses and decrease tissue metabolic efficiency and thus enhance cerebral injury in the preterm infant. The angiotensin-converting enzyme (ACE) DD genotype is associated with raised ACE and RAS activity as well as potentially adverse stimuli such as inflammation. The DD genotype has been associated with neurological impairments in the elderly, and thus may be also associated with poorer motor or cognitive development amongst children born preterm prematurely. Methods The association of DD genotype with developmental progress amongst 176 Caucasian children born at less than 33 weeks gestation (median birthweight 1475 g, range 645–2480 g; gestation 30 weeks, range 22–32; 108 male) was examined at 2 and 5 1/2 years of age. Measured neuro-cognitive outcomes were cranial ultrasound abnormalities, cerebral palsy, disability, Griffiths Developmental Quotient [DQ] at 2 yrs, and General Cognitive Ability [British Ability Scales-11] and motor performance [ABC Movement], both performed at 5 1/2 yrs. All outcomes were correlated with ACE genotype. Results The DD genotype was not associated with lower developmental quotients even after accounting for important social variables. Conclusion These data do not support either a role for ACE in the development of cognitive or motor function in surviving infants born preterm or inhibition of ACE as a neuroprotective therapy.</p
*WINNER* Layered DD Coil: An Improved Coil Structure For Wireless Power Transfer
No full textWireless power transfer is gaining application in electric vehicles and in the charging of biomedical implants. Inductance is a primary property that enables wireless power in an inductive wireless power transfer (IWPT) system. It indicates both the power storing and sharing capability of the coil involved.The Double Dee (DD) coil is a coil type that has shown a significant amount of inductance for this purpose. To increase the DD coil inductance, more turns and a much wider area are required. With an area constraint, this will limit the use of the DD coil. In this research, a Layered DD coil is presented to further enhance the inductance capability of the DD coil and overcoming the area constraint. Multiple layers of the coil are used and the coils are oriented such that the emanating magnetic field adds up constructively thereby enhancing the coil inductance. Simulation and experimental implementation of the coil have shown an enhanced and superior performance in comparison to the parent DD coil. The use of shielding materials will enhance its overall performance and prevent or reduce the potential hazard of the field. Various shielding materials known to have good magnetic properties were investigated to determine their effect on IWPT. Ferrite, Cobalt-Iron, Steel were among the materials used and which showed significant prospects in IWPT. It was deduced based on their performance that cobalt-iron would enable a higher amount of power to be transmitted than ferrite. Other configurations of the LDD coil show the potential for cost-saving
DD-Pose: A large-scale Driver Head Pose Benchmark
No full textWe introduce DD-Pose, the Daimler TU Delft Driver Head Pose Benchmark, a large-scale and diverse benchmark for image-based head pose estimation and driver analysis. It contains 330k measurements from multiple cameras acquired by an in-car setup during naturalistic drives. Large out-of-plane head rotations and occlusions are induced by complex driving scenarios, such as parking and driver-pedestrian interactions. Precise head pose annotations are obtained by a motion capture sensor and a novel calibration device. A high resolution stereo driver camera is supplemented by a camera capturing the driver cabin. Together with steering wheel and vehicle motion information, DD-Pose paves the way for holistic driver analysis. Our experiments show that the new dataset offers a broad distribution of head poses, comprising an order of magnitude more samples of rare poses than a comparable dataset. By an analysis of a state-of-the-art head pose estimation method, we demonstrate the challenges offered by the benchmark. The dataset and evaluation code are made freely available to academic and non-profit institutions for non-commercial benchmarking purposes

Evidence for B-0 -> D+D- and observation of B-->(DD-)-D-0 and B-->(DD*-)-D-0 decays
No full textWe report evidence for B-0 -> D+D- and the first observation of the decay modes B-->(DD-)-D-0 and B-->(DD*-)-D-0 based on a sample of 152x10(6) B (B) over bar events collected by the Belle detector at KEKB. The branching fractions for B-0 -> D+D-, B-->(DD-)-D-0, and B-->(DD*-)-D-0 are found to be (1.91 +/- 0.51 +/- 0.30)x10(-4), (4.83 +/- 0.78 +/- 0.58)x10(-4), and (4.57 +/- 0.71 +/- 0.56)x10(-4), respectively. Charge asymmetries in the B-->(DD-)-D-0 and B-->(DD*-)-D-0 channels are consistent with zero
The Influence of Intellectual/Developmental Disabilities (I/DD) Curriculum Content on Career Interests for Social Work Students
No full textThis study examines how curriculum content on Intellectual/Developmental Disabilities (I/DD) impacts the career interests of social work students. With the growing demand for social workers proficient in I/DD services, it is crucial to understand how educational experiences shape career choices. Using a QUANT→Qual mixed-method approach, this quasi-experimental pre/post-test survey combined quantitative data (N 66 [experimental group]; N =103 [control group] and open-ended survey questions (N = 66 [experimental group]; N =103 [control group] from social work students.
The author-constructed survey assessed student attitudes, perceptions, preparedness, ability to identify I/DD, knowledge of I/DD, and willingness to practice with individuals with I/DD before and after exposure to I/DD-focused curriculum content over a 15-week period. The quantitative findings indicated that exposure to I/DD-focused curriculum content significantly improved students’ preparedness, ability to identify I/DD, knowledge about I/DD, and willingness to work with this population. Qualitative findings indicated that students who completed the I/DD courses reported increased confidence and interest in pursuing careers involving I/DD roles. The study findings emphasize the importance of including dedicated I/DD content in social work education to better equip future practitioners
The riskiness and the reinsurance in life portfolio with Dread-Disease coverage
No full textIn this paper we present final results of a research on the riskiness of a life policies
portfolio with “dread disease” (briefly: DD) coverage in additional or early form, referring
to the insurer’s point of view. By means of first and second moments of the random present
value of gain on a single policy, portfolio ruin probability’s estimates are derived under
either Cebicev-Cantelli’s inequality or normal distribution hypothesis, in presence of a low
positive correlation among risks and also introducing optimal strategies referred to a
surplus reinsurance treaty to face the correlation’s effects.
By means of numerical applications based on insurance company’s experiences we
show the riskiness and the ruin probability considerably increase when a binary correlation
exists and we demonstrate the inefficiency of the EEC minimum solvency margin rule,
even in presence of optimal reinsurance strategies
