We exploit a novel setting in which the same piece of information affects two sets of firms: one set of firms requires straightforward processing to update prices, while the other set requires more complicated analyses to incorporate the same piece of information into prices. We document substantial return predictability from the set of easy-to-analyze firms to their more complicated peers. Spe...

Atmospheric phase is the main factor affecting accuracy of ground-based synthetic aperture radar. The atmospheric screen (APS) may be very complicated, due to drastic changes in conditions, and conventional correction methods based on regression models cannot fit correct it effectively. Partition a feasible path improve (APC) for complicated APS, but overfitting problem ignored. In this article...

Kolmogorov complexity has proven to be a very useful tool in simplifying and improving proofs that use complicated combinatorial arguments. In this paper we use Kolmogorov complexity for oracle construction. We obtain separation results that are much stronger than separations obtained previously even with the use of very complicated combinatorial arguments. Moreover the use of Kolmogorov argume...

Dear Editor-in-Chief The recent report on “The Adverse Effects of Pregnancies Complicated by Hemoglobin H (HBH) Disease” is very interesting (1). Rabiee et al. reported a pregnant case complicated with HBH disease. Indeed, this problem might not common in the Middle East but it is very common in Southeast Asia. The authors hereby would like to share the experience on this top...

Background and Objectives: Death of a child can be the source of many problems for mothers. Therefore, the present study aimed to investigate the effects of the spiritual-religious intervention on complicated grief disorder and the psychological hardiness of mothers suffering from this disorder. Methods: The present quasi-experimental study was conducted using a pretest-posttest design with a ...

This study examined the effectiveness and feasibility of therapist-guided Internet-delivered exposure (EX) and behavioral activation (BA) for complicated grief and rumination. Forty-seven bereaved individuals with elevated levels of complicated grief and grief rumination were randomly assigned to three conditions: EX (N=18), BA (N=17), or a waiting-list (N=12). Treatment groups received 6 homew...
