Abstract We define isoclinism of skew braces and present several applications. study some properties that are invariant under isoclinism. For example, we prove right nilpotency is an invariant. This result has application in the theory set‐theoretic solutions to Yang–Baxter equation. isoclinic multipermutation

Background Measurement of thoracic deformities is difficult and therefore little information is available about the effectiveness of conservative treatment. While from a specialized center in Brasil positive case reports have been released for the treatment of all kinds of genuine thoracic deformities with the help of braces [1], the German health insurances in part do reject the costs of such ...

The high-density epicardial mapping plaque used in this study provides coverage of 10% of the atria and hence has a narrow field of view relative to the global bi-atrial surface area. Thus from a segment of atria mapped, we could only determine whether a rota-tional circuits or a focal source is present and not whether it was critical in driving wavefronts elsewhere in the atria. It is possible...

Using induction heat (IH) treatment to locally transform one half of a steel brace section high-strength as well inducing intentional eccentricity along the length has been experimentally proven increase limited post-yielding stiffness exhibited by conventional braces. This paper develops multi-level seismic design method for intentionally eccentric IH-treated braced frames (IH-FIEB) support th...

INTRODUCTION Valgus knee braces are effective at decreasing pain and improving function in patients with knee osteoarthritis (OA) [1]. The braces are designed to decrease loading in the medial knee compartment but previous studies are unclear if this truly occurs. Alternatively, changes in the neuromuscular system might account for the benefits of bracing. An earlier study with a small sample d...

The equivalent force control (EFC) method replaces numerical iteration with a feedback control strategy to solve the nonlinear equations of motion in pseudodynamic and real-time substructure tests (RST) using an implicit integration method. The EFC method and its further development with an energy conserving integration method are presented in this paper. The effectiveness and accuracy of the E...

Although malocclusion correction is the major reason for orthodontic treatment, these braces are occasionally worn aesthetic or fashion reasons. These can be colourful and may of many different shapes than those used treatment. Using false dental offered by quacks could endanger patients' oral health. However, people, particularly young still find fake appealing. We present two cases where colo...
