So far, various components of image characteristics have been used for steganalysis, including the histogram characteristic function, adjacent colors distribution, and sample pair analysis. However, some certain steganography methods have been proposed that can thwart some analysis approaches through managing the embedding patterns. In this regard, the present paper is intended to introduce a n...

IMPORTANCE There are limited data on the use of the supraclavicular artery island flap (SCAIF) for parotid and lateral skull base (LSB) surgery. This flap can be an important reconstructive tool for these procedures. OBJECTIVE To describe the use of the SCAIF for parotid and LSB surgery and its success, as well as important technique modifications for successful use of the flap in this settin...

0 . 1 8 ~ CMOS process. The DAC is optimized for circuit calibration in large ASICs and occupies 0.01034 mm’ (1 IOW x 9 4 ~ ) of die area. Creative layout and current mirroring techniques are implemented to minimize area while providing output current with sufficient headroom. The measured DNLfiNL is better than 0.7/0.75 LSB and OH2 LSB for 1.8V and 1.4V power supplies, respectively. The DAC co...

Least Square Backpropagation(LSB) algorithm is employed to train a three-layer neural network for segmentation of Magnetic Resonance(MR) brain images. The simulation results demonstrate the use of LSB neural Network as a promising method for the segmentation of multi-modal medical images. The training time has been dramatically reduced comparing with that of BP network. The influence of the num...

This paper proposes a 240 frames/s 2.1 M-pixel CMOS image sensor with column-shared cyclic ADC that consumes low power of 90 μW/column at 1.5 V supply and is applicable to the fine pixel pitch of 2.25 μm. The prototype sensor was fabricated in a 0.13-μm 1P4M CMOS technology. The measured DNL and INL are +0.59/-0.83 LSB and +2.8/-3.6 LSB, respectively. The measured maximum pixel rate is 500 Mpix...

The aim of the steganography methods is to communicate securely in a completely undetectable manner. LSB Matching and LSB Matching Revisited steganography methods are two general and esiest methods to achieve this aim. Being secured against first order steganalysis methods is the most important feature of these methods. On the other hand, these methods don't consider inter pixel dependency. The...

As we all know security is needed when we want to send data over any medium so this requires a secure medium to send data. That’s why steganography comes in mind whose aim is to send data securely without knowing of any hacker. In this paper, a new technique is projected whose aim is to keep secrete communication intact. The proposed method blends the advantage of 2 bit LSB and XOR operation. I...

We serendipitously find a new nearby Low Surface Brightness (LSB) galaxy from SDSS database. We estimate oxygen abundance of its H ii region SDSS J121811.0+465501.2 from electron temperature, as well as for another H ii region, SDSS J135440.5+535309.6, located in irregular LSB galaxy UGC8837. These two extragalactic H ii regions were classified as stars in the SDSS-DR4 database, and were found ...
