پس از معرفی مختصری از نظریه گره در فصل اول، در فصل دوم ساده ترین و در عین حال پایه ای ترین چندجمله ای در مبحث گره ها یعنی چندجمله ای براکت کافمن را معرفی خواهیم کرد. در ادامه به روشی برای محاسبه این چندجمله ای اشاره می کنیم که به طرز چشمگیری خطای محاسبه را کاهش می دهد. در فصل سوم به چندجمله ای جونز خواهیم پرداخت. این چندجمله ای با پاسخ به مسائلی که تا مدت ها بدون پاسخ مانده بودند به مانند انق...

Background: True umbilical cord knot is one of the abnormalities of the umbilical cord. Active fetal movements create cord knotting. True umbilical cord knots are rare but may be associated with fetal distress and stillbirth. True umbilical cord knots are capable of impeding blood flow to the fetus.Case presentation: A 26-year old primigravid woman was first treated for genital herpes simplex v...

Introduction: A knot is a non-intersecting closed curved in 3-space. The projection of a knot onto the plane yields a knot diagram of the knot. The crossing number of a knot is the minimum number of self-crossings a knot has among all its knot diagrams. We may manipulate a given knot diagram by twisting and moving the curve so that the new diagram obtained after such manipulations is still that...

PURPOSE The purpose of this study was to determine the optimal knot configuration that maximized both knot and loop security when tied with 2 different types of nonabsorbable, braided suture. TYPE OF STUDY In vitro biomechanical study. METHODS Six commonly used arthroscopic sliding knots (Duncan loop, Nicky's knot, Tennessee slider, Roeder knot, SMC knot, Weston knot) with and without a ser...

PURPOSE There are many options for arthroscopic knots including the type of knot and suture material used. The current investigation evaluated knot properties using 3 high-strength suture materials tied in 5 common arthroscopic knot configurations. METHODS Four arthroscopic sliding knots including the Roeder, Weston, SMC, and Tennessee Slider and an arthroscopic nonsliding Surgeon's knot were...

The Yoon Soon (YS) knot is a laparoscopic extracorporeal slip knot that is easy to learn and apply. Our new technique, which uses the trocar as a knot pusher, is simpler, faster, and has more tension than conventional knot methods. The YS knot will help surgeons save operative time and perform tension-controlled knot-tying during laparoscopic surgery.

PURPOSE To compare the knot characteristics of a pretied suture knot with 3 of the most commonly used arthroscopic knots tied with various high-strength sutures. METHODS Three commonly used arthroscopic knots (surgeon's knot, Seoul Medical Center, and Duncan loop) tied with no. 2 high-strength sutures were compared with a pretied knot secured with either 1, 2, or 3 reversed half hitches (RHAP...

Sliding knots are commonly used in arthroscopic surgery and can be problematic in terms of strength and loop security. A new sliding knot for arthroscopic surgery, a modified racking hitch (MRH) knot, is described. The knot is essentially a modified cow's hitch knot that includes two self-locking loops. By tensioning the loop strands, a snug knot is created without backward sliding and provides...
