We study a low-energy effective field theory (EFT) describing the NN system in which all exchanged particles are integrated out. We show that fitting the residue of the S1 amplitude at the deuteron pole, rather than the S1 effective range, dramatically improves the convergence of deuteron observables in this theory. Reproducing the residue ensures that the tail of the deuteron wave function, wh...

Vitiligo is a dermatosis requiring complex treatment. In clinically stable cases, melanocyte autologous grafting has shown good results, using different methodologies for obtaining the donor area: dermatomes, punches, blisters. However, these techniques are complex and require specific instruments. This study presents a simple technique for melanocyte harvest that has been performed in our serv...

Over nearly the past 30 years, U.S. children and adolescents have dramatically increased their consumption of sugarsweetened beverages (SSBs), including soda, fruit drinks and punches, and sports drinks (see sidebar for a more complete definition).6,7 Such consumption has been linked to less healthy diets and a number of other negative health consequences, including decreased bone density, dent...

In this study, patterned microindents are generated on the surface of NiTi shape memory alloy by laser shock assisted direct imprinting (LSADI). During LSADI, the plasma pressure generated by the laser pulse punches the mask into the target material and thus generates patterned indents. It has been demonstrated that thermally controllable surface pattern can be generated on NiTi surface through...

PURPOSE: Performance in boxing is a combination of strength, speed, and stability to create maximum impact. One the types punches commonly used straight punch. The magnitude force exerted at point impact influenced by number factors. Therefore, some biomechanical parameters can have greater effect than others during punch performance. Likewise, different technique modalities influence force. Th...

Generally, thin cylindrical shells are susceptible for geometrical imperfections like non-circularity, non-cylindricity, dents, swellings etc. All these geometrical imperfections decrease the static buckling strength of thin cylindrical shells. In this work, neighbourhood effect of two circumferential short dents on the buckling behaviour of thin short stainless steel cylindrical shell is studi...
