We study disorder-induced propagation losses of guided modes in photonic crystal slabs with line-defects. These losses are treated within a theoretical model of size disorder for the etched holes in the otherwise periodic photonic lattice. Comparisons are provided with state-of-the-art experimental data, both in membrane and Silicon-on-Insulator (SOI) structures, in which propagation losses are...

A model to calculate the economic losses of mastitis on an average Dutch dairy farm was developed and used as base for a tool for farmers and advisors to calculate farm-specific economic losses of mastitis. The economic losses of a clinical case in a default situation were calculated as euro210, varying from euro164 to euro235 depending on the month of lactation. The total economic losses of ma...

We postulate that exogenous losses–which are typically regarded as introducing undesirable “noise” that needs to be filtered out or hidden from end points–can be surprisingly beneficial. In this paper we evaluate the effects of exogenous losses on transmission control loops, focusing primarily on efficiency and convergence to fairness properties. By analytically capturing the effects of exogeno...

Bag silos made at three research farms in 2000 and 2001 were monitored at filling and emptying to determine densities and losses. A total of 47 bags (23 alfalfa, 1 red clover, 23 whole−plant corn) were made, and losses were calculated on 39 of the silos. Dry matter (DM) density ranged from 160 to 270 kg/m3. Dry matter density increased with DM content in hay crop silages on average 2.9 kg/m3−% ...

OBJECTIVES to evaluate the epidemiological profile, the surgical treatment and the postoperative results of patients with complex traumatic injuries to the lower limbs. METHODS we conducted a retrospective study of patients with traumatic complex injuries treated by the Plastic Surgery Service of a regional hospital in Brasília. We analyzed clinical-epidemiological data, type of surgical proc...

In this study we use a high-quality data set of in situ ozone measurements at a suburban site called Mohali in the state of Punjab to estimate ozone-related crop yield losses for wheat, rice, cotton and maize for Punjab and the neighbouring state Haryana for the years 2011–2013. We intercompare crop yield loss estimates according to different exposure metrics, such as AOT40 (accumulated ozone e...

The objective of this experiment was to compare the effects of belt grill and Open Hearth electric broiler cookery on palatability and cooking traits of longissimus steaks. The longissimus thoracis from carcasses of grain-fed steers or heifers was used. Duplicate measurements were made for Warner-Bratzler shear force at 3 and at 14 d after slaughter (n = 180) and trained sensory evaluation at 1...

We examine effects of state-level job losses on student achievement. Job losses to 1% of states’ working-age populations decrease states’ eighth-grade math scores by .076 standard deviations. This result is an order of magnitude larger than effects in studies comparing students whose parents lose employment to otherwise similar students, suggesting that downturns affect all students, not just s...

I Abstract In the process of designing an electric power supply system for an aircraft, parameters like low weight and low losses are important. Reliability, robustness and low cost are other important factors. In the Saab Gripen aircraft, the design of the primary power supply of the electric flight control system was updated by exchanging a switching transistor regulator to a magnetic amplifi...
