Data on quantum dot cellular automata based flip flops for designing serial-in-serial-out shift register.

There has been remarkable research carried out on Nano-electronics where Quantum dot Cellular automata emerge as the forthcoming paradigm in computing. The QCA-based circuits are used in the computational Nano hardware to present computations at ultra-high speed. A systematic approach has been utilized to design the Serial in Serial out Shift (SISO) Register using JK flip flop (JK-FF) and D flip flop (D-FF).

Predicting childhood lead exposure at an aggregated level using machine learning.

Childhood lead exposure affects over 500,000 children under 6 years old in the US; however, only 14 states recommend regular universal blood screening. Several studies have reported on the use of predictive models to estimate lead exposure of individual children, albeit with limited success: lead exposure can vary greatly among individuals, individual data is not easily accessible, and models trained in one location do not always perform well in another. We report on a novel approach that uses machine learning to accurately predict elevated Blood Lead Levels (BLLs) in large groups of children, using aggregated data.

Electrochemical deposition of amorphous aluminum oxides on lead pipes to prevent lead leaching into the drinking water.

Over 5000 public drinking water systems in the US are out of compliance with the Lead and Copper Rule. Lead leaching from lead pipes is limited by the solubility of a naturally occurring scale. Changes in water quality may cause this scale to become more soluble, releasing lead into the drinking water.

Closed-loop Electroencephalogram-based modulated audio to fall and deepen sleep faster.

The transition from wake to sleep is a continuum that is well characterized by the electroencephalogram (EEG) power spectral ratio (ρ) between the beta (15 to 30 Hz) and theta (4 to 8 Hz) bands. From wake to sleep, the value of ρ gradually decreases.We have designed and implemented a single EEG-signal based closed-loop system that leverages ρ to modulate the volume of a pink-noise type of audio such that the volume becomes gradually softer as sleep initiates.

Customised antenatal growth charts.

Charts for fetal growth do not take physiological variables into account. We have therefore designed a computer-generated antenatal chart that can be easily "customised" for each individual pregnancy, taking the mother's characteristics and birthweights from previous pregnancies into consideration. The adjusted birthweight range expected at 40 weeks' gestation is combined with a standard, longitudinal ultrasound-derived curve for intrauterine weight gain.
