These notes are a short introduction to the pinch technique. We present the one-loop calculations for basic QCD Green's functions. The equivalence between the pinch technique and the background field method is explicitly shown at the one-loop level. We review the absorptive pinch technique in the last sections. These lectures are a compilation of famous papers on this subject and are prepared f...

PURPOSE To examine the impact of prolonged graphomotor tasks on tripod-pinch strength and on handwriting process and product measures of children with dysgraphia and typical peers. METHOD Participants were 51 children in third to fifth grades, divided into two groups: 23 children with dysgraphia and 28 typical peers, as determined by the Handwriting Proficiency Screening Questionnaire. The pr...

We present frames from high-speed videos of the pinch-off of liquid 4He droplets. The temperature of the fluid droplets ranged from 1.33 K to 4.8 K, and the size of the drops was proportional to the temperature-dependent capillary length. We observed no qualitative difference between pinch-off in the normal and superfluid states. In both cases, the shape of the fluid in the final stages of pinc...

Cells attach to the extracellular matrix (ECM) through integrins to form focal adhesion complexes, and this process is followed by the extension of lamellipodia to enable cell spreading. PINCH-1, an adaptor protein essential for the regulation of cell-ECM adhesion, consists of five tandem LIM domains and a small C-terminal region. PINCH-1 is known to interact with integrin-linked kinase (ILK) a...

BACKGROUND Carpal tunnel syndrome (CTS) compromises fine sensorimotor function during activities of daily living. Reach-to-pinch for a small object requires not only dexterity of the grasping digits, but also coordinated transport of the hand to the target. This study examined the effects of CTS on the kinematic performance of reach-to-pinch maneuver. METHODS Eleven CTS subjects and 11 able-b...

Although strength is one of the important characteristics of a normal hand, this factor is not given enough attention in reconstructive surgery as compared to other parameters of motion and sensibility. This paper presents the results of a study on strength in functional adaptations of the normal hand. A baseline of normal grip and pinch strength was obtained by testing a group of one hundred h...
