Thirty patients with isolated patellofemoral complications after total knee arthroplasty were compared with 20 patients with well functioning total knee replacements without patellofemoral complications. The epicondylar axis and tibial tubercle were used as references on computed tomography scans to measure quantitatively rotational alignment of the femoral and tibial components. The group with...

An experiment was carried out to compare the digestibility of five concentrate ingredients (barley, beet pulp, citrus pulp, maize gluten feed and grain screenings) in cattle or sheep, fed at 1.2 maintenance. Four wether sheep and four steers were fed each concentrate, which comprised 800 g/kg of the dietary dry matter (DM). The remaining 200 g/kg was a hay/soyabean meal mixture whose digestibil...

Regular expressions are a frequently used tool to search in large texts. They provide the ability to compare against a structured pattern that can match many text strings and are common to many applications, even programming languages. This paper extends the problem to the private two-party setting where one party has the text string and the other party has the regular expression. The privacy c...

Thirty-two Suffolk wether lambs were fed for 84 d in a 2 x 2 factorial experiment using two levels of dietary protein (9.0 to 12.1% CP, low protein, LP; or 12.8 to 14.4% CP, high protein, HP) and supplemental Cr (none, C; or 400 ppb Cr as chromium tripicolinate, Cr). At 14- to 21-d intervals, lambs were weighed, and jugular blood samples were collected. Mean ADG and carcass weight (P > .10) did...

In two separate 2 x 2 factorial arrangements, 69 male, crossbred lambs were allotted randomly to the following treatments: 1) nonimplanted (NI) rams, 2) implanted (I) rams, 3) NI wethers, and 4) I wethers. In Trial 1, 36 lambs were allotted to treatment groups at birth (n = 9) and I lambs were implanted with 12 mg of zeranol between 1 and 3 d of age and again at weaning (average age of 62 d). L...

Biological effects of ultrasound involve nonlinear phenomena in qualitatively different ways. (1) The propagation of sound itself is nonlinear. Most nonthermal bioeffects of interest to users of diagnostic ultrasound require acoustic pressures great enough that the wave becomes distorted by nonlinear propagation. Under 1imi ting conditions this process can increase the absorption parameter of w...

We considered a distributed model of computing where nodes in a graph contain processors and they can talk to their immediate neighbors. The goal now is to collectively compute something. In particular for the maximal independent set problem the goal is to a pick a set of nodes S such that S is a maximal independent set of the underlying graph and each node determines whether or not it is in S....

In a quest for better understanding the shaping mechanism of planetary nebulae (PNs) I published many papers in the past (e.g., Soker 2004a) all of which came to the same conclusion: For the formation of non-spherical PNs a companion is required, wether stellar or substellar. This results from the basic assumption that angular momentum is a conserved physics quantity. As trivial as this may sou...
