Chest X-ray (CXR) images can be used to diagnose a variety of lung diseases, such as tuberculosis, pneumonia, and cancer. However, the variation in morphology due differences age, gender, severity pathology makes high-precision segmentation challenging task. Traditional networks, U-Net, have become standard architecture achieved remarkable results field image tasks. because traditional convolut...

High performance magnetic heads, inductors and transformers, indispensable to information technology encompassing from information storage, portable power delivery, to wireless communication, require soft magnetic films with low coercivities, high permeability, and large ferromagnetic resonance frequencies. The Fe-Co-N-based films have a ferromagnetic resonance frequency of >1 GHz at zerobias f...

Debra Galvan Nordstrom, COTA, is employed al Health South Rehabilitation Hospital, Humble, Texas. (Mailing address: 14545 Bammel NOrlh HouSLOn Road, Apt. 901, HouSLOn, Texas 77014) Gastroesophageal reflux (GER) is a disorder that affects many infants. GER is a malfunc­ tion of the distal esophageal sphincter that causes frequent return of stomach contents into the esophagus (Herbst, 1981). If u...

We present the properties of new Dirac-type operators generated by real or complex-valued special Killing-Yano tensors that are covariantly constant and represent roots of the metric tensor. In the real case these are just the so called complex or hyper-complex structures of the Kählerian manifolds. Such a Killing-Yano tensor produces simultaneously a Dirac-type operator and the generator of a ...

The FPGA-QQ (Field Programmable Gate Array Quick Queue) is a novel, efficient priority queue implementation targeted specifically for FPGAs. This paper describes its architecture and use in acceleration of the FPGA routing problem. FPGA-QQ utilizes the FPGA’s blocks of on-chip memory to store keys and values in a completely ordered fashion. The use of the on-chip block memory allows hundreds to...

Para verificar a influência da altitude na estrutura anatômica de folhas e do xilema secundário galhos indivíduos espécie Clethra scabra Pers. (Clethraceae) ocorrentes Serra Mantiqueira, estado Minas Gerais, realizaram-se coletas amostras nas cotas altitudinais 1500, 1700, 1900 2100 m (metros). As coletados foram fixados preparados seguindo procedimentos usuais microtécnica vegetal. Procederam-...
