Background and aims Using free quadriceps tendon graft for anterior cruciate ligament (ACL) reconstruction has become more popular in the last years due to the low morbidity at the harvest site and biomechanical and structural properties similar to other types of graft (hamstring and patellar tendons). As long as the tibial tunnel fixation with interference screws is considered the standard fix...

Although single-loop tibialis tendon allografts have increased in popularity owing to their many advantages over patellar tendon and double-loop hamstring tendon autografts, some percentage of the patient population do not have clinically stable knees following anterior cruciate ligament reconstruction with single-loop tibialis tendon allografts. Therefore, it would be advantageous to determine...

A bstract Our work focuses on utilizing the Berends-Giele currents to construct differential operators and unifying relations for 1-loop Feynman integrands. We successfully reproduce known results between Yang-Mills theory scalar theory, extend discussion (A)dS case with minimal coupling gluons.

Loop is a powerful program construct in classical computation, but its power is still not exploited fully in quantum computation. The exploitation of such power definitely requires a deep understanding of the mechanism of quantum loop programs. In this paper, we introduce a general scheme of quantum loops and describe its computational process. The notions of termination and almost termination ...

Various extensions of public announcement logic have been proposed with quantification over announcements. The best-known extension is called arbitrary public announcement logic, APAL. It contains a primitive language construct ✷φ intuitively expressing that “after every public announcement of a formula, formula φ is true.” The logic APAL is undecidable and it has an infinitary axiomatization. ...

A recently developed active electronic personal dosemeter (AEPD) was utilised in order to measure the levels and the structure of occupational exposure to scattered X-ray radiation of medical staff who performed percutaneous revascularisation therapy that involves interventional radiology (IR) on the pelvis and upper leg arteries. The AEPDs, placed on the operators' and assistants' chests, that...

We find that scattering amplitudes in massive scalar QCD can manifest the duality between color and kinematics at loop-level. Specifically we construct one-loop integrands for four-point two distinct scalars, five-point process encoding first correction to with gluonic radiation. factorization color-kinematics are sufficient principles entirely bootstrap these calculations, allowing us all cont...

I study dynamic games where players may be unaware of some fundamentals of the game itself, such as actions or players, and such unawareness may be lifted by other players’ actions during the play. Based on Li (2006a, 2006b), I propose a framework to deal with such games using standard tools of game theory. I construct examples to show that unawareness is distinctly different from assigning zer...

Humble leadership behavior consists of acknowledging personal faults, mistakes and limits; spotlighting their followers’ contributions and strengths; modeling teachability. Previous studies have suggested that humble leadership behavior leads to a number of positive outcomes for organizations, such as high levels of learning goal orientation, performance and engagement, yet almost nothing has b...

Here we deal with the stabilisation problem of non-diagonal systems by boundary control. In studied setting, control input is subject to a constant delay. We use spectral decomposition method and split system into two components: an unstable stable one. To stabilise part system, connect, for first time in literature, famous backstepping design technique direct-proportional design. More precisel...
