Risk arbitrage trading and the characteristics of arbitrage spreads : the Canadian evidence
… The arbitrage spread is defined as the percentage difference between the bid price and market price one day after the initial announcement. I also demonstrate that the cross-sectional variation of these spreads is high, and negative in some instances. Buying the targets of the entire …

Hydrodynamic characterisation of soil subsurface flows for water conservation purposes.
… at different depths, which reveal a marked difference in their behaviour. Nonetheless, the range of values is smaller than the predicted curve. At 200 mm depth, the value of n is noticed to be 15 with 𝜃𝑟 of 0.046 and 𝜃𝑠 of 0.23 for the packed soil sample, giving a percentage difference of …

Non-invasive early diagnosis of deep vein thrombosis
… (eye) method for experimental programme. The percentage difference between vein valve closure times of result from automatic tracking and baseline is 3.57%. Therefore, it showed that the proposed method is applicable and able to tracking the vein valve movement.

Efavirenz pharmacogenetics and metabolic toxicity in black South Africans
… between CYP2B6 metaboliser genotypes and the percentage difference in metabolic parameters from baseline to week 48 using univariate and multivariate linear regression models. Results: A total of 171 participants were successfully genotyped. Median baseline age was 32 years, CD4 count was 292 …

Sensitivity Analysis of Hot/Cold Pixel Selection in SEBAL Model for ET Estimation
… selection based on land cover map, normalized difference vegetation index (NDVI) map, and land surface temperature (LST) map. Various combinations of hot/cold pixels were automatically selected along the LST gradient. The LE estimations were then validated against ground-based eddy covariance …

Effects of indoor air quality on the occupant's health and productivity in an office building
… with the measured value, and found that the percentage difference were in the range of 1.5% to 8.45% (below than 10%). Once the model had been validated, the parametric study of air supply inlet position was conducted on the model and found that the position of air supply inlet with x = 2.5 …

Projecting fertility by educational attainment: proof of concept of a new approach
… with the observed fertility estimates. The percentage difference between the projected and WPP fertility estimates varied from 1 to 5 percent in Lesotho, Namibia and Zimbabwe. In conclusion, the model can also be used for other countries. Furthermore, education composition change should be …

Exploring limb symmetry index for balance across a range of functional tasks.
… and Excel. Results: No statistically significant differences occurred between dominant and non-dominant limb for any of the assessed tasks. The absolute mean percentage difference between limbs was 4.9%±3.7% (95% CI 1.8% - 8.0%). ICC values ranged from 0.73 – 0.96 suggesting moderate to excellent …

Optimisation of galaxy identification methods on large interferometric surveys
… and parametrization tools. A fraction of the percentage difference in the performance of these automated tools corresponds to a significant number of galaxies being detected or undetected. Failure or success to resolve satellites around big spirals will affect both the low and the high mass …

Holonic-based control system for automated material handling systems
… The experimental results obtained show a percentage difference between the makespan values obtained using the holonic scheduling approach and the optimal values of under seven percent. Since current control systems in use in industry lack the ability to adapt to dynamic manufacturing …

Effects of Microwave Irradiation on the Dimensional Stability of Complete Denture Bases
… being tested were estimated by using the percentage difference between the baseline area of each denture base and each test group. Data was statistically analyzed using a 2-way repeated measures ANOVA; followed by the Tukey HSD test. Statistical analysis was conducted at the 95% level of …

Prediction of mobile network subscriber satisfaction by using network probing experience measures and machine learning
… Neutrals or Detractors, and calculating the percentage difference between promoters and detractors. The more positive the value, the better overall customer perception is likely to be. A key shortcoming of NPS is that it does not provide tangible and directly interpretable reasons for …

Order Fulfillment Algorithms for Online Retail
… The experiments show a 50% reduction in the mean percentage difference in shipping cost from the hindsight solution as compared to the LP-based algorithm. In addition to the fulfillment algorithm, we formulate a capacity planning problem that determines the optimal level of transportation …

Assessing Variabilities of Extreme Precipitation and Snow Depth Using Climate and Stochastic Models
… results show that 70% of CMIP6 models exhibit a percentage difference of ±10% in annual maxima mean and variation. However, CMIP6 simulations generally overestimate daily SD by at least 10%, with some regions challenging to simulate due to their complex atmospheric and land interactions, such as …
