High-linearity modified uni-traveling carrier photodiodes on silicon-on-insulator with low AM-to-PM conversion factor are demonstrated. The devices deliver more than 2.5 dBm RF output power up to 40 GHz and have an output third order intercept point of 30 dBm at 20 GHz. Photodiode arrays exceed a saturation current-bandwidth-product of 630 mA · GHz and reach unsaturated RF output power levels o...

The increase in demand for high data transmission rates and channel capacity has led to the evolution of Free Space Optical (FSO) communication links. In this paper, performance analysis of a high-speed free space optical communication link has been observed. The performance of 10 Gbps FSO link has been evaluated on the basis of Q Factor, SNR ratio, and total power of the received signal for a ...

In the United States, demineralized bone matrix (DBM) is considered a transplantable tissue and therefore is regulated primarily by the American Association of Tissue Banks. Even though DBM is not subjected to the same regulations relative to performance claims as medical devices are, one would expect different processing methods might yield DBM preparations of different osteoinductive potentia...

A pretraining algorithm, which is a layer-bylayer greedy learning algorithm, for a deep Boltzmann machine (DBM) is presented in this paper. By considering the deep belief net type of pretraining for the DBM, which is a simplified version of the original pretraining of the DBM, two interesting theoretical facts about pretraining can be obtained. (1) By applying two different types of approximati...

Articular cartilage injury is still a significant challenge because of the poor intrinsic healing potential of cartilage. Stem cell-based tissue engineering is a promising technique for cartilage repair. As cartilage defects are usually irregular in clinical settings, scaffolds with moldability that can fill any shape of cartilage defects and closely integrate with the host cartilage are desira...

Spinal fusion is a gold-standard treatment for many disorders of the spine with autogenous bone graft as the gold-standard source for augmenting fusion. However, the morbidity and limitations of autogenous bone grafting has motivated the search for bone graft alternatives. One such alternative is demineralized bone matrix (DBM). The purpose of this paper is to describe and characterize the prop...

Since 1996, as part of a cooperative ARS/CIRAD Plutella biocontrol program, 115 Plutella populations have been collected in 32 countries from cole crops and cruciferous weeds. Twenty-seven primary hymenopterous parasitoid species were found, especially Diadegma spp., Cotesia plutellae and Oomyzus sokolowskii. A number of fungal pathogens, isolates of Paecilomyces fumosoroseus, Paecilomyces sp.,...

BACKGROUND Distraction osteogenesis (DO) is a promising tool for bone and tissue regeneration. However, prolonged healing time remains a major problem. Various materials including cells, cytokines, and growth factors have been used in an attempt to enhance bone formation. We examined the effect of percutaneous injection of demineralized bone matrix (DBM) during the consolidation phase on bone r...

Initially, the paper provides an introduction to the main aspects of existing timedomain methods for identifying linear continuous-time models from discrete-time data and shows how one of these methods has been applied to the identification and estimation of a model for the transportation and dispersion of a pollutant in a river. It then introduces a widely applicable class of new, nonlinear, S...
