abstract   background: traumatic or congenital events can result in injury and functional deficiency in the hand and we need to reconstruct the fingers at times. studies are available in the pediatric and adult age groups to assess the length of the thumb. but to the best our knowledge no measurement of the relative clinical length of all fingers has been reported in the literature. we performe...

background: asthma is a common condition in general medical practice, and it accounts for about 1% of all ambulatory hospital visits. nowadays, hospitalization rates for asthma have actually been increased in some demographic subgroups despite recent advances in treatment. understanding the underlying factors that contribute to hospitalization and especially duration of the hospitalization of a...

We study the spatiotemporal structure of the biphoton entangled state generated by the four-wave mixing (FWM) process in a cold two-level atomic ensemble. We analyze, for the first time, the X-like shaped structure of the biphoton entangled state and the geometry of the biphoton correlation for different lengths and densities of the cold atomic ensemble. The propagation equations of the photon ...

The present study provides a further investigation of the neighborhood-frequency effect. Using the masked priming procedure, we found that the neighborhood-frequency effect is obtained not only with primes and targets of the same length but also with primes and targets of a different length. This result is not compatible with most current versions of the interactive activation model. Implicatio...

For phase transitions in disordered systems, an exact theorem provides a bound on the finite size correlation length exponent: nFS $ 2yd. It is believed that the intrinsic n satisfies the same bound. We argue that the standard averaging introduces a noise and a new diverging length scale. For n # 2yd self-averaging breaks down, disconnecting n from nFS, and the bound applies only for the latter...

On the basis of observations of arterial pulse forms in anesthetized dogs, a hypothesis is developed to account for the genesis of the aortic standing wave which is responsible for the dicrotic characteristics of pulses recorded from the abdominal-femoral system. A sudden lowering of resistance to pulse wave propagation in the region of the diaphragm and an increase in resistance in the periphe...

This paper presents a common algorithmic framework encompassing the two main methods for using an abstract solution to guide search. It identifies certain key issues in the design of techniques for using abstraction to guide search. New approaches to these issues give rise to new search techniques. Tw o of these are described in detail and compared experimentally with a standard search techniqu...

A close logical analysis is given of Einstein’s proof of the relativity of lengths and times. It turns out that in proving the relativity of lengths and times, some results concerning universal time and the true length of an object are exploited; or rather, for different inertial observers different definitions of length and synchronization of clocks are made, due to the deeply rooted influence...

Recent evidence suggests that the ratio of the lengths of the second and fourth fingers (2D:4D) may reflect degree of prenatal androgen exposure in humans. In the present study, we tested the hypotheses that 2D:4D would be associated with ratings of men's attractiveness and with levels of behavioral displays during social interactions with potential mates. Our results confirm that male 2D:4D wa...
