Viewpoint-invariant Weber fractions and standard contour-curvature discrimination [PDF]
It is proposed that any cue for the visual discrimination of shape, in particular the discrimination of curved contours, should be such that the perceptual relationships defined by the cue are invariant under changes in observer viewpoint. Such relationships may be quantified by the Weber fraction; that is, the ratio Δc/c, where, for any particular ...

Malleability of the approximate number system: effects of feedback and training
Prior research demonstrates that animals and humans share an approximate number system (ANS), characterized by ratio dependence and that the precision of this system increases substantially over human development. The goal of the present research was to

On the edge: haptic discrimination of edge sharpness. [PDF]
The increasing ubiquity of haptic displays (e.g., smart phones and tablets) necessitates a better understanding of the perceptual capabilities of the human haptic system.

Extraction of the neural count function from the Weber fraction [PDF]
It is shown that the dependence of the Weber fraction, ΔI/I, on I determines the form of the neural firing rate function N(I) provided that the relation between ΔN and N is given. Here, ΔN is the change in average firing rate resulting from an intensity jnd. The firing rate function consistent with Weber's law is predicted when ΔN ∼ N1/2. Assuming that

Some theorems on the explicit evaluation of Ramanujan's theta-functions
Bruce C. Berndt et al. and Soon-Yi Kang have proved many of Ramanujan's formulas for the explicit evaluation of the Rogers-Ramanujan continued fraction and theta-functions in terms of Weber-Ramanujan class invariants.

Liquid-Liquid Flow Pattern Prediction Using Relevant Dimensionless Parameter Groups
Accurate predictions of flow patterns in liquid-liquid flow are critical to the successful design and operation of industrial and geo-energy systems where two liquids are jointly transported.

Effect of retrogression re-aging treatment on corrosion behavior of 7055 Al-Zn-Mg alloy
The effect of retrogression re-aging treatment (RRA) on the corrosion behavior of 7055 Al-Zn-Mg alloy was studied in this paper. Results provided that corrosion resistance could be greatly improved by RRA.

Significant Inter-Test Reliability Across Approximate Number System Assessments
The approximate number system (ANS) is the hypothesized cognitive mechanism that allows adults, infants, and animals to enumerate large sets of items approximately. Researchers usually assess the ANS by having subjects compare two sets and indicate which
