Semi-solid materials undergo strain localization and shear band formation as a result of granular nature of semi-solid deformation. In the present study, to analyze the shear localization, a unified viscoplastic constitutive model was developed for the homogeneous flow. Then, a linearized analysis of the stability performed by examining the necessary condition for the perturbation growth. For t...

Previous research indicated that 4-month-old infants perceive continuity of objects moving on horizontal trajectories but appear to have difficulty processing occlusion events involving oblique trajectories. However, because perception of continuity of vertical trajectories has not been tested, it is uncertain whether this indicates a specific deficit for oblique trajectories or a specific adva...

PURPOSE To develop and test a method for automatically calculating the in-plane rotation for doubly-oblique slice geometry in order to minimize wrap artifacts for a given FOV. MATERIALS AND METHODS The equations for in-plane rotation were formulated for doubly-oblique imaging of a cylindrical body with elliptical cross-section. Based on this formulation, automatic in-plane rotation was implem...

A reexamination is made of one-loop oblique electroweak corrections. General definitions are given of the oblique parameters without reference to any q-expansion scheme. The old oblique parameters S,T and U are defined as differences of gauge boson vacuum polarization Π-functions and suffice to describe certain observable ratios on the Z-peak and the ρ parameter at q = 0. Regarding the new obli...

To identify ARIX gene and PHOX2B gene polymorphisms in patients with congenital superior oblique muscle palsy, 3 exons of the ARIX gene and PHOX2B gene were sequenced by genomic DNA amplification with polymerase chain reaction (PCR) and direct sequencing in 31 patients with congenital superior oblique muscle palsy and in 54 normal individuals. A family with a father and one daughter each having...

BACKGROUND Inguinal herniotomy is the most common surgery performed by pediatric surgeons. AIM To compare the results and complications between two conventional methods of pediatric inguinal herniotomy with and without incising external oblique aponeurosis in terms of recurrence of hernia and other complications. METHODS This one blinded clinical trial study was conducted on 800 patients wi...

[Purpose] This study aimed to determine the effect of abdominal muscle activities and the activation ratio related to trunk stabilization to compare the effects between the abdominal drawing-in maneuver and lumbar stabilization exercises on an unstable base of support. [Subjects and Methods] Study subjects were 20 male and 10 female adults in their 20s without lumbar pain, who were equally and ...

Body-tilt effect on the haptic discrimination of orientations and the 'oblique effect' (better discrimination of the vertical orientation than of an oblique orientation) were examined in 5-month-old infants. Body tilt leads to a mismatch between egocentric and gravitational reference frames and indicates in which reference frame orientations and oblique effect are defined. A familiarization/rea...

The experiment examined the human visual perception of orientations and the nature of reference frame in which the oblique effect (lower performance in oblique orientations than in vertical or horizontal ones) was defined. Previous research [M. Luyat, E. Gentaz, Body tilt effect on the reproduction of orientations: studies on the visual oblique effect and subjective orientations, J. Exp. Psycho...

BACKGROUND Ultrasound (US) guidance during central venous catheterization (CVC) reduces complications and improves success rates compared to landmark-guided techniques. A novel "oblique view" (US transducer held at approximately 45° with respect to the target vessel) has been suggested to be superior to the standard short-axis approach usually used during US-guided CVC. OBJECTIVES The purpose...
