Modern spectrometer equipment tends to be expensive, thus increasing the cost of emerging systems that take advantage of spectral properties as part of their operation. This paper introduces a novel technique that exploits the spectral response characteristics of a traditional sensor (i.e. CMOS or CCD) to utilize it as a low-cost spectrometer. Using the raw Bayer pattern data from a sensor, we ...

A patient who underwent a successful double-vessel percutaneous transluminal coronary angioplasty (PTCA) had suffered from exercise-induced ST-segment elevation associated with angina pectoris (AP). This ECG pattern was present both before and 12 months after PTCA while nifedipine (Adalat; Bayer-Miles) therapy was electively discontinued. Reintroduction of calcium blockade with this drug elimin...

A single-chip image sensor used in almost all consumer and in some professional-grade digital cameras today is affixed with an alternating pattern of spectrally shifted (in the electromagnetic wavelength sense) color filters to each pixel location. The arrangement of color filters, which are typically the canonical color triples (i.e. red, green, blue), is called color filter array (or CFA) [1,...

Acetylsalicylic acid was synthesized by Gerhardt in 1853 and even put on the market during the 1880s by the firm Merck.1 Yet the proper history of this medicine begins only in 1897, now more than a hundred years ago, when this miracle amongst medicines was again synthesized at the dyestuffs factory of Friedrich Bayer and the chemical factory of Friedrich von Heyden. About eighteen months later ...

STUDY QUESTION What is the bleeding pattern during second consecutive levonorgestrel-releasing intrauterine system (LNG-IUS) use? SUMMARY ANSWER Consecutive use of LNG-IUS is associated with a predictable bleeding pattern, characterized by the absence of the initial period of irregular bleeding seen after interval insertion of an LNG-IUS and a non-bleeding pattern in the vast majority of wome...

Spatially varying exposure (SVE) is a promising choice for high-dynamic-range (HDR) imaging (HDRI). The SVE-based HDRI, which called single-shot an efficient solution to avoid ghosting artifacts. However, it very challenging restore full-resolution HDR image from real-world with SVE because: a) only one-third of pixels exposures are captured by camera in Bayer pattern, b) some the over- and und...

An angiomyolipoma (AML) is a benign mesenchymal tumor composed of blood vessels, smooth muscle cells, and a varying amount of fat. The liver is the second most common site of AML involvement, after the kidney. In general, hepatic AML can be easily suggested as a diagnosis by identifying the abundant fatty component seen on computed tomography (CT) or magnetic resonance imaging (MRI). However, i...

Abstract We introduce subwavelength color routers with perfect optical efficiency in a red-green-green-blue (RGGB) Bayer layout for solid state image sensors. This is the first demonstration of device concept that shows full potential routing, i.e., routing without loss photons, broadband, polarization-independent, and angular robust response. As an example, we show router 320 nm wide sensor pi...
