In this paper, we propose a new definition of energy efficiency with respect to a given target packet error rate (PER). It is shown that some previous reported definitions are actually special cases of our definition. Consequently we use the definition to analyze the energy efficiency of Multilevel quadrature amplitude... |
The story of women’s participation in popular culture is more complex than the struggle to be included. Feminist activists have fought for legislation to end discrimination in leisure, sports, and popular culture. At the same time, advertisers have coopted feminism to sell a variety of products as symbols of emancipati... |
PURPOSE |
This study was performed to investigate the incidence of thrombophilic gene mutations in repeated assisted reproductive technology (ART) failures. |
METHODS |
The prevalence of mutated genes in the patients with a history of three or more previous ART failures was compared with the patients with a history of successful pregnancy following ARTs. The study group included 70 patients, 34 with three or more previously failed ARTs (A) and control group consisted of 36 patients wi... |
RESULTS |
Mutation of FVL gene was detected in 5.9% women of group A (2 of 34) compared with 2.8% women (1 of 36) of control group (P = 0.6). Mutation of MTHFR gene was found in 35.3% (12 cases) as compared with 50% (18 cases) of control (35.3% versus 50%; P = 0.23). Regarding Prothrombin, only control group had 5.6% mutation (P... |
CONCLUSION |
The obtained results suggest that thrombophilia does not have a significant effect in ART failures.Comparative Study of Feature Reduction Techniques in Software Change Prediction |
Software change prediction (SCP) is the process of identifying change-prone software classes using various structural and quality metrics by developing predictive techniques. The previous studies done in this field strongly confer the correlation between the quality of metrics and the performance of such SCP models. Pa... |
Tumor hypoxia is an important indicator of cancer prognosis. Among the different genes that are upregulated by hypoxia is carbonic anhydrase IX, which combines carbon dioxide and water to form bicarbonate and hydrogen. Although expression of this enzyme is very low in normal tissues, carbonic anhydrase IX is overexpres... |

Juglans regia is an economically highly important species for fruit and wood production in the warm temperate and subtropical zones of the Northern Hemisphere. Besides the natural influence of climatic and geomorphological barriers, its genetic structure has been strongly modified by humans and the population history i... |
Many temperate animals spend half their lives in a non-active, overwintering state, and multiple adaptations have evolved to enable winter survival. One notable vertebrate model is Chrysemys picta, whose hatchlings display dichotomous overwintering strategies: some hatchlings spend their first winter aquatically after ... |
In this work we present the stability analysis of a tracking Proportional-Derivative (PD) robot manipulator controller, with variable P and D gains. We show that under a proper selection of the bounds of the variable gains, the tracking error is uniformly ultimately bounded. Simulations of the controller tuned by a sel... |
This article focuses on the distributed cooperative compound tracking issue of the vehicular platoon. First, a definition, called compound tracking control, is proposed, which means that the practical finite-time stability and asymptotical convergence can be simultaneously satisfied. Then, a modified performance functi... |

The scale and complexity of advanced cyber-physical systems (CPSs) are steadily growing. Most new-generation CPSs being developed or to be developed involve networked embedded computing (NEC) devices. The state of the art in software engineering for such network-based CPSs is weak. Major problems faced are the low qual... |
A quantitative model is presented which enables contributions to the surface potential of a monolayer at the air-water interface to be determined from known values of group dipole moments. Based on the Lennard-Jones and Dent approach, the model shows that the head- and tail-group moments in a condensed, long-chain, n-a... |
Cyclin E is altered in nearly a third of invasive breast cancers where it is a powerful independent predictor of survival in women with stage I-III disease. Full-length cyclin E is posttranslationally cleaved into low molecular weight (LMW-E) isoforms, which are tumor-specific and accumulate in the cytoplasm because th... |

BACKGROUND |
Clinical significance of delayed-onset neutropenia (DON) after autologous hematopoietic stem-cell transplantation (ASCT) has not been well described. We conducted a retrospective cohort study to examine risk factors and clinical impact of DON. |
DESIGN AND METHODS |
Subjects were consecutive 108 patients with B-cell lymphoma receiving ASCT. We defined DON as absolute neutrophil counts <1.0 x 10(9)/l at any point from 30 days onward after ASCT without apparent causes of neutropenia. Documented infectious events were reviewed from 1 to 18 months after ASCT. |
RESULTS |
Fifty-two percent of patients received rituximab. Cumulative incidence of DON was 50% at 1 year. Rituximab usage was identified as an independent risk factor of DON. A total of 117 infectious events were documented, of which 24 events occurred during DON period. Cumulative incidence of total infectious events was 75% a... |
CONCLUSIONS |
Rituximab usage is an independent risk factor of DON. DON correlates with increased occurrence of infectious events. Careful follow-up would be needed after the onset of DON.Remembering Forgetting: Maladies de la Memoire in Nineteenth-Century France |

Positive real conditions and differential sector conditions have recently been shown to imply global convergence w.p. 1, for recursive identification schemes based on a class of single-input/single-output linear Wiener models. The models consist of linear dynamics followed by a static output nonlinearity. The model str... |
We consider a model system of a permanent magnet above a semi-infinite superconductor, introduce a modified critical-state model, and carry out derivations of the levitation force acting on the magnet. A key feature of the modification allows the current density to be less than the critical value. Theoretical results s... |
Now almost 70 years since its introduction, the effective or half-light radius has become a very popular choice for characterising galaxy size. However, the effective radius measures the concentration of light within galaxies and thus does not capture our intuitive definition of size which is related to the edge or bou... |
