Background: External fixation has been one of the conventional managements of unstable distal radius fracture. The main aim of this paper is to compare two methods of applying distractive force along the radius shaft versus perpendicular to the distal radius articular surface. Design: Sixty patients with unstable distal radius fracture were included in present clinical trial and randomized in two groups, using block randomization method. In group A (first arm), distraction force was exerted parallel to the radius shaft. In group B (second arm), the external fixator was adjusted based on radial and palmar tilt of the mean population healthy wrist so that distraction was exerted perpendicular to the wrist articular surface. Methods: Radiological and clinical parameters were evaluated in both groups of patients pre-operatively, immediately after surgery, and 6 weeks post-operatively. We also followed up patients clinically at 12 weeks after surgery. Patient-Rated Wrist Evaluation (PRWE), Mayo wrist score, and Quick Disabilities of the Arm, Shoulder and Hand (DASH) questionnaires were used in order to assess patients' clinical and functional states. Results: The method used in group B resulted in better improvement of palmar tilt both immediately (P = 0.007) and at 6 weeks follow up (P = 0.013) post-operatively in comparison with patients in group A. Radius height and radial inclination were also better restored when using the proposed modified method (P = 0.001 and < 0.001, respectively). There was no difference in any of clinical results (range of motion, grip strength, PRWE, Mayo, and DASH scores) between two groups of study, 12 weeks after surgery. Conclusion: Applying distractive force perpendicular to the distal radius articular surface seems to improve some radiological outcomes, probably due to better reduction maintenance, when compared with the technique of applying distraction force along distal radius shaft axis. Level of Evidence: Level I (clinical trial study). Trial registration: This study is registered at Iranian Registry of Clinical Trials (IRCT) with approval code of IRCT20200313046759N1.

Behaviour of glulam beams loaded perpendicular to the grain This paper discusses the behaviour of glulam beams loaded perpendicular to the grain. A series of 101 tests was performed where the support length and the load situation were varied. The results are compared to the load carrying capacities calculated with the currently valid model of EN 1995-1-1:2010. The deformations across the beam height are analysed. Based on the modulus of elasticity, conclusions on load distribution and the contribution of continuous wood fibres on the effective contact area are drawn. The factor kc,90 is dependent on the load distribution. On this basis, a model to calculate the load carrying capacity perpendicular to the grain in dependence of an accepted deformation is discussed. [ABSTRACT FROM AUTHOR]

We shall obtain the interaction of the - and -branes in the toroidal-orbifold space-time . The configuration of the branes is nonintersecting, perpendicular, moving-rotating, wrapped-fractional with background fields. For this, we calculate the bosonic boundary state corresponding to a dynamical fractional-wrapped -brane in the presence of the Kalb-Ramond field, a gauge potential and an open string tachyon field. The long-range behavior of the interaction amplitude will be extracted. [ABSTRACT FROM AUTHOR]

This paper proposes the perpendicular local binary pattern (PLBP) for efficiently describing textures in an interest region. Its novelty is two-fold: (1) the candidate generation scheme provides a set of patterns for each pixel, instead of conventionally assigning one pattern per pixel, and (2) an adaptive threshold based on the image contrast of a region is used. These modifications successfully enhance the robustness of PLBP to Gaussian noise as well as in near-uniform regions. We introduce the novel multi-scale region PLBP descriptor, which adopts the PLBP as its core feature. It defines multiple support regions from an interest point, sequentially performs ring-shaped and intensity order-based segmentations on each region, and pools PLBPs to corresponding segments. These steps are controlled easily by a set of parameters, thus offering high flexibility. Experimental results on challenging benchmarks, including three datasets of image matching and two datasets of object recognition, demonstrate the effectiveness of the proposed descriptor in handling common photometric and geometric transformations. It significantly improves the robustness, compared with current state-of-the-art descriptors, while maintaining a reasonable operational cost. [ABSTRACT FROM AUTHOR]

The dielectric and ferroelectric properties of Fe-doped BaTiO3ceramic under uniaxial stress applied perpendicular and parallel to the electric field are presented and analyzed. For the dielectric properties, the results showed that the uniaxial stress reduced an electric permittivity and dielectric losses for the both directions of applied stress. It was also found that an applied uniaxial pressure also enhanced a diffuse phase transformation behaviour. In the case of the ferroelectric properties the applied stress weakens a polarization when it is applied parallel (p∥ac) to the electric field. These results were interpreted through the stress induced domain switching process. [ABSTRACT FROM AUTHOR]
