We describe a high-speed long-depth range optical frequency domain imaging (OFDI) system employing a long-coherence length tunable source and demonstrate dynamic full-range imaging of the anterior segment of the eye including from the cornea surface to the posterior capsule of the crystalline lens with a depth range of 12 mm without removing complex conjugate image ambiguity. The tunable source...

Gradient-descent-based digitized adjoint method offers a way to realize the high-efficiency inverse design of digital nanophotonic devices with diverse functions. However, vanishing gradient problem encountered in high-dimension may lead significant inefficiencies, making it difficult integrate novel functions on single chip. Here, we propose highly efficient for large-scale design, called adap...

The study was conducted in 2022 with a sample of 100 respondents. Red gram respondents were divided into three farms groups marginal, small and medium (27, 13, 10 Maruti 27, 14 9 Charu variety), respectively. Marketing cost variety Rs.760/qtl Rs.780/qtl channel I, Rs.1190/qtl II. margin Rs. 600/ha I Rs.950/ha Rs.930/ha Price spread 1360 Rs.1340/ha 2140/ha Rs.2110/ha II efficiency 6.55 6.1 6.85 ...

No âmbito da historiografia medieval, em diversos momentos encontramos uma relação minuciosa entre o presente e passado. Tal favoreceu, no ato historiográfico, a transição de elementos estes dois tempos, muitas das vezes transportando significados os mesmos. Neste artigo, analisamos objeto historiográfico Vida y hechos heroicos del gran condestable Portugal D. Nuño Alvares Pereyra Conde Barcelo...

A data management system can be separated in typical data processing systems. Unfortunately, relational data management systems are not efficient enough to handle the on-line signal processing task in a monitoring system. The main current in research into database management system model for the needs of monitoring systems is connected with a data stream model. However, these systems are non-de...

We would like to provide a clarification to the reader about our article ‘‘Efficacy and Treatment Costs of Monotherapy with bDMARDs in the Treatment of Rheumatoid Arthritis in Patients Intolerant to or Inappropriate to Continue Treatment with Methotrexate’’ published in issue 33, pp 1360–1373. In Italy tocilizumab adheres to the payback system, so its ex-factory price does not include the ex-an...

Fine-grained isotropic graphite is the material of choice for the production target and the beam catchers at the planned Super-FRS fragment separator at FAIR. Heavyion irradiation studies of graphite are needed, as radiation damage will ultimately limit the lifetime of these components. Polycrystalline graphite and highly-oriented pyrolytic graphite (HOPG) were irradiated with energetic ions an...

Using digital image processing of particle streak photography, the streamwise and perpendicular components of the velocity field were investigated, in the mid-span plane of a two-dimensional mixing layer, with a 6: I velocity ratio. The Reynolds number of the flow, based on the local vorticity thickness and the velocity difference across the layer, ranged from 1360 to 2520, in the plane of obse...
