PBTI degradation on FinFETs with HfO2/TiN gate stack (EOT < 1 nm) is studied. Thinner TiN layer decreases interfacial oxide thickness, and reduces PBTI lifetime. This behavior is consistent with the results in planar devices. Corner rounding effect on PBTI is also analyzed. Finally, charge pumping measurements on devices with several fin widths devices apparently show a higher density of defect...

Evans, N., Robinson, V. P., and Lister, J. (1972). Archives of Disease in Childhood, 47, 589. Growth and bone age of juvenile diabetics. The growth of a group of juvenile diabetics on restricted carbohydrate diets has been studied using standardized techniques. Most patients were distributed between the 10th and 90th centiles for height, weight, bone age, and subscapular skinfold thickness. The...

Six statistics are compared in a simulation study for their ability to identify geographical areas with a known excess incidence of a rare disease. The statistics are the standardized incidence ratio, the empirical Bayes method of Clayton and Kaldor, Poisson probability, a statistic based on the 'Breslow T' test (BT) and two statistics based on the 'Potthoff-Whittinghill' test (PW) for extra-Po...

The suppression of photon bremsstrahlung due to a variety of in-medium effects is discussed. Different electrodynamic suppression effects are discussed, and compared with the related color analogs. Higher order effects are considered, and found to be important. Data from SLAC E-146 is discussed, and compared with theory. The effect of finite thickness targets is emphasized, since nuclear size i...

The propagation of Love waves in a non-homogeneous layer of finite thickness lying over an isotropic semi-infinite medium is discussed in this study. It is assumed that density and rigidity are space dependent and obey the laws  (1+cosz), μ=μ0 (1+cosz), where ‘’is a scaling parameter. The method of variable separation, substitution method for solving the second order partial differen...

We deal with the interaction between three coplanar Griffith cracks located symmetrically in the mid plane of an orthotropic layer of finite thickness 2h. The Fourier transform technique is used to reduce the elastostatic problem to the solution of a set of integral equations which have been solved by using the finite Hilbert transform technique and Cooke’s result. The analytical expressions fo...

OBJECTIVES To compare the physiological and anthropometric characteristics of specific playing positions and positional playing groups in junior rugby league players. METHODS Two hundred and forty junior rugby league players underwent measurements of standard anthropometry (body mass, height, sum of four skinfolds), muscular power (vertical jump), speed (10, 20, and 40 m sprint), agility (L r...

Introduction Examples of cohort studies in the sexual health literature are now increasingly common. The purpose of this article is to provide an overview of the design and analysis of cohort studies, along with a discussion of some of the potential problems with these studies which may be particularly relevant for cohorts which study factors related to sexual health. A comprehensive guide to t...

Abstract PURPOSE To evaluate the macular, retinal nerve fiber layer (RNFL) and choroidal thickness alterations by using spectral-domain optical coherence tomography (SD-OCT) in postmenopausal, pregnant non-pregnant women. PATIENTS AND METHODS A comparative study included a total of 42 eyes (Right eye) healthy females period from march 2019 to September divided into 3 groups: a) Non b) Pregnant ...
