A simple and model-independent method is proposed to extract information on νe transition into antineutrinos via the spin flavor precession (SFP) from the measurements of solar neutrino flux at SNO and Super-Kamiokande. Incorporating the KamLAND experimental results, we examine how large the suppression of the solar neutrino flux could be due to the SFP mechanism in the context of the hybrid sc...

El uso creciente de las métricas de Puntos Función para la gestión de proyectos de software ha promovido el desarrollo de variantes del Análisis de Puntos Función para aproximar el tamaño funcional cuando la documentación, el tiempo o los recursos disponibles no permiten realizar el cálculo estándar. Scenario Function Points (SFP) es un procedimiento basado en el método IFPUG que permite estima...

Oxidative stress is a mediator of cell death following cerebral ischemia/reperfusion and heme toxicity, which can be an important pathogenic factor in acute brain injury. Induced expression of phase II detoxification enzymes through activation of the antioxidant response element (ARE)/Nrf2 pathway has emerged as a promising approach for neuroprotection. Little is known, however, about the neuro...

Sperm competition is a potent postcopulatory selective force where sperm from rival males compete to fertilize a limited set of ova. Considering that sperm production is costly, we expect males to strategically allocate sperm in accordance with the level of competition. Accordingly, previous work has examined a male's strategic allocation in terms of sperm number. However, the seminal fluid pro...

A new circadian variant was isolated by screening the intercross offspring of wild-caught mice (Mus musculus castaneus). This variant was characterized by an initial maintenance of damped oscillations and subsequent loss of rhythmicity after being transferred from light-dark (LD) cycles to constant darkness (DD). To map the genes responsible for the persistence of rhythmicity (circadian ratio) ...

The plasmid is a very well-known mobile genetic element that participates in the acquisition of virulence genes, such as staphylococcal enterotoxins (SEs), via horizontal transfer. SEs are emetic toxins and causative agents in staphylococcal food poisoning (SFP). We herein identified the types of plasmids harbored by seven SFP isolates and examined their production of plasmid-related SE/SEl to ...

The use of deep-frozen boar semen for artificial insemination (AI) is constrained by the need for high sperm numbers per dose, yielding few doses per ejaculate. With the advancement of new, intra-uterine insemination strategies, there is an opportunity for freezing small volumes containing high sperm numbers, provided the spermatozoa properly sustain cryopreservation. The present study aimed to...

PURPOSE We tested whether effects of the Strengthening Families Program for Youth 10-14 (SFP10-14) diffused from intervention participants to their friends. We also tested which program effects on participants accounted for diffusion. METHODS Data are from 5,449 students (51% female; mean initial age = 12.3 years) in the PROmoting School-community-university Partnerships to Enhance Resilience...

The Escherichia coli entD gene, which encodes an Sfp-type phosphopantetheinyl transferase (PPTase) that is involved in the biosynthesis of siderophore, is available as a high-expression ASKA clone (pCA24N::entD) constructed from the E. coli K-12 strain AG1. In E. coli DH5alpha, pCA24N::entD complemented a pfaE-deficient clone that comprised pfaA, pfaB, pfaC and pfaD, which are four of the five ...

Article history: Received 12 June 2008 Available online 31 December 2008 Stochastic fictitious play (SFP) assumes that agents do not try to influence the future play of their current opponents, an assumption that is justified by appeal to a setting with a large population of players who are randomly matched to play the game. However, the dynamics of SFP have only been analyzed in models where a...
