in this study, the profitability of contrarian and momentum strategies were traded in mid- term based on trading volume. the stocks were categorized into three parts (high, middle and low) at the outset. then, the relationship between excess return with three components such as cross-sectional risk, lead-lag effect and time-series pattern were examined based on jegadeesh and titman approach.the...

background: the eradication of helicobacter pylori infection, commonly prevailing in the stomach, has been important since its introduction. adequate preparations should be made in finding alternatives when faced with first-line treatment failures. currently, ideal second-line treatments are indistinct and varied among countries as result of different antibiotic resistance patterns. we aimed to...

The increasing complexity of construction, along with its rapid development, as well as ambiguities and gaps in the legal terms governing constructions, lack of trust in the parties regarding obligations and regulations are the main reasons of disagreements in domestic projects. These disagreements are inevitable even in contracts which are set correctly. Disagreements are costly, time-consumin...

Picosecond laser pulses have been used to produce Rydberg wave packets in calcium atoms in the presence of a strong static electric field. The dynamics of the Stark wave packets have been observed by measuring the momentum-space probability distribution as a function of time. The full precession of the electronic orbital angular momentum, the appearance of a large-amplitude, linear oscillation ...

The properties of the Das-Popowicz Moyal momentum algebra that we introduce in hep-th/0207242 are reexamined in details and used to discuss some aspects of integrable models and 2d conformal field theories. Among the results presented we setup some useful convention notations which lead to extract some non trivial properties of the Moyal momentum algebra. We use the particular sub-algebra sln−Σ̂...

OBJECTIVE To assess the short-term tolerability of lorcaserin alone or with two dose regimens of phentermine. METHODS This was a 12-week, randomized, double-blind, pilot safety study of N = 238 nondiabetic patients with obesity or overweight with ≥1 comorbidity randomized to lorcaserin 10 mg twice daily (BID; LOR BID) alone or with phentermine 15 mg once daily (QD; LOR BID+PHEN QD) or 15 mg t...

although response to intranasal steroid therapy has been reported in pa¬tients with allergic rhinitis, efficacy of some nasal steroids is noteworthy. this study was undertaken to evaluate the efficacy of a two-week course of fluticasone (flixonase) nasal spray vs. beclomethasone (beconase) nasal spray in patients with symptoms of allergic rhinitis referred to our clinic. this study reviewed six...
