On fixed points of Berinde’s contractive mappings in cone metric spaces
2010
In this paper we establish some common fixed point theorems for two self-mappings satisfying a generalized contractive condition. This result generalizes well known comparable results in the literature. As an application, a necessary and sufficient condition for a fixed point to be a periodic point for the mapping involved therein, without appealing to continuity, in a cone metric space is established.
Fixed point results in cone metric spaces for contractions of Zamfirescu type
2010
We prove a result on points of coincidence and common fixed points in cone metric spaces for two self mappings satisfying a weak generalized contractive condition of Zamfirescu type. We deduce some results on common fixed points for two self mappings satisfying a weak contractive type condition. These results generalize some well-known recent results.
Status of Advanced Virgo
2017
The LIGO and the Virgo collaborations have recently announced the first detections of Gravitational Waves. Due to their weak amplitude, Gravitational Waves are expected to produce a very small effect on free-falling masses, which undergo a displacement of the order of 10-18 m for a Km-scale mutual distance. This discovery showed that interferometric detectors are suitable to reveal such a feeble effect, and therefore represent a new tool for astronomy, astrophysics and cosmology in the understanding of the Universe. To better reconstruct the position of the Gravitational Wave source and increase the signal-to-noise ratio of the events by means of multiple coincidence, a network of detectors…
Coupled coincidence point results for (φ,ψ)-contractive mappings in partially ordered metric spaces
2014
Abstract. In this paper, we extend the coupled coincidence point theorems for a mixed g-monotone operator F : X × X → X $F:X\times X\rightarrow X$ obtained by Alotaibi and Alsulami [Fixed Point Theory Appl. (2011), article ID 44], by weakening the involved contractive condition. Two examples are given to illustrate the effectiveness of our generalizations. Our result also generalizes some recent results announced in the literature. Moreover, some applications to integral equations are presented.
Psychological Profile in Female Cyclists and Its Relationship with Age, Training Parameters, Sport Performance, and Injury Incidence.
2021
Previous studies have highlighted the importance of psychology on sports performance and its relationship with the incidence of sport injuries. The objectives of the present investigation were: (1) to analyze the psychological profile of female cyclists as a function of age, training parameters, sport performance, and injuries suffered and (2) to design a model to predict their psychological profile. Sixty-one female cyclists participated in the study. Differences were found as a function of a competitive category for team cohesion (F = 5.035

INCIDENCIA DE LA DISLEXIA EN ECUADOR: RELACIÓN CON EL CI, LATERALIDAD, SEXO Y TIPO DE ESCUELA
2015
El presente estudio revisa la incidencia de la dislexia en 207 estudiantes de primaria, de 8 a 13 años de edad, que asisten a instituciones públicas y privadas en la ciudad de Cuenca (Ecuador). Se encontró un porcentaje de 26.57% de sujetos de los cuales el 36% presentó dislexia superficial, el 33% dislexia fonológica y el 31% dislexia mixta. Posteriormente se comparan variables como sexo, lateralidad, CI y tipo de escuela, siendo estas dos últimas las que evidencian diferencias significativas. Se discuten las circunstancias que reportan una incidencia tan elevada en esta investigación.
Effects of air pollution on dementia over Europe for present and future climate change scenarios.
2020
The scientific literature is scarce when referring to the influence of atmospheric pollutants on neurodegenerative diseases for present and future climate change scenarios. In this sense, this contribution evaluates the incidence of dementia (Alzheimer's disease, AD, and dementia from unspecified cause, DU) occurring in Europe associated with the exposure to air pollution (essentially NO2 and PM2.5) for the present climatic period (1991-2010) and for a future climate change scenario (RCP8.5, 2031-2050). The GEMM methodology has been applied to air pollution simulations using the chemistry/climate regional model WRF-Chem. Present population data were obtained from NASA's Center for Socioecon…
Hospitalization for self-harm during the early months of the Covid-19 pandemic in France: a nationwide study
2020
ABSTRACTIntroductionLittle is known to date about the impact of Covid-19 pandemic on self-harm incidence.MethodsThe number of hospitalizations for self-harm in France (mainland and overseas) from January to August 2020 (which includes the first confinement from March 17th to May 11th) was compared to the same period in 2019-2017. Hospital data with the ICD-10 codes X60-84 were extracted from the national administrative database (PMSI).ResultsThere were 53,583 hospitalizations for self-harm in France between January and August 2020. Compared to the same period in 2019, this represents an overall 8.5% decrease. This decrease started the first week of the confinement and the number of hospital…
Effect of the IL28B Rs12979860 C/T polymorphism on the incidence and features of active cytomegalovirus infection in allogeneic stem cell transplant …
2013
The current study was aimed at investigating whether the single nucleotide polymorphism (SNP) (rs12979860), upstream of the IL28B gene, had any effect on the incidence rate and the features of active CMV infection in the Allogeneic stem cell transplantation setting. This was a retrospective observational study including 151 patients undergoing T cell-replete Allo-SCT. Donor and recipient IL28 SNP genotype was determined by allele-specific real-time PCR. The incidence rate of active CMV infection was not significantly associated with either the donor or the recipient IL28B SNP genotype. Nevertheless, a trend towards a lower incidence of active CMV infection was noted in the donor T/T populat…
