Electronic documents are more easily copied and redistributed than paper documents. This is a major impediment to electronic publishing. Illegal redistribution can be discouraged by placing unique marks in each copy and registering the copy with the original recipient. If an illegal copy is discovered, the original recipient can be identified. In this work we describe several invisible techniqu...

This paper presents a novel approach to measuring and mapping shape and motion of the water surface. The approach combines and borrows from existing techniques, such as stereo imaging shape recognition and tracking, infrared (IR) laser marking and thermography, and particle image velocimetry. The system consists of a high power IR laser beam controlled by a programmable marking head and two IR ...

In (1) the syntactic functions of S (gizona ‘man’ in 1a) and O (mutila ‘boy’ in 1b) are identically coded, while in (2) it is S (muzhchina ‘man’ in 2a) and A (muzhchina in 2b) that are identically coded. That is, the two languages differ in whether S is aligned with A or O. Henceforth we refer to syntactic functions such as A, O, and S as argument roles. Argument structure has to do with the nu...

The Distributed Denial-of-Service attack is a serious threat in Internet and an effective method is needed for distinguishing the attack traffic from the legitimate traffic. We propose the concept of bit marking to identify and drop the attack packets. Bit marking is a variation of packet marking technique that modifies the packet header at each router. However bit marking differs from packet m...

It has recently been shown that nucleosome distribution, histone modifications and RNA polymerase II (Pol II) occupancy show preferential association with exons ("exon-intron marking"), linking chromatin structure and function to co-transcriptional splicing in a variety of eukaryotes. Previous ChIP-sequencing studies suggested that these marking patterns reflect the nucleosomal landscape. By an...

the relationship between some habitat factors and fish assemblage was analyzed in the taleghan river, alborz province, iran. fish specimens from thirty-three sites were sampled by electrofishing device in october 2014. the habitat parameters, including elevation (m), water depth (cm), river width (m), river slope (%), current velocity (m.s-1), number of large stone (> 15 cm), average stone diam...

carcinogenesis is a multistep process characterized by the gradual accumulation of genetic changes that ultimately lead to cancer. these genetic mutations can impart limitless replicative potential to the cancer cells making them immortal. telomeres are repeat nucleotide sequence ttaggg that are present at the end of chromosomes. its functions are to protect the chromosomal ends and to ensure t...

n≥0 Γ(nKMg). Mg has been proven to be of general type for g ≥ 22 [EH,Fa,HaMu]. In particular in this case the finite generation of the canonical ring implies that the canonical model is birational to Mg. Recent progress has been made in this area. For example [BCHM] have proved the existence of canonical models in the case of smooth projective varieties of general type. A somewhat easier proble...

Differentiated Services (Diffserv) which was proposed by Internet Engineering Task Force (IETF), is a scalable and robust model for providing the end-to-end QoS. In the Diffserv networks, metering mechanisms are used to measure traffic stream. The single rate Three Color Meter (srTCM) [1],which was proposed by IETF,‏ meters an IP packet stream and marks its packets either green, yellow, or red....

This paper discusses the diachronic development of non-structural case marking in TibetoBurman and in computer simulations of language evolution. It is shown how case marking is initially motivated by the pragmatic need to disambiguate between two core arguments, but eventually may develop flagging functions that even extend into the intransitive domain. Also, it is shown how different types of...
