Chemical exchange saturation transfer (CEST) of metabolite protons that undergo exchange processes with the abundant water pool enables a specific contrast for magnetic resonance imaging (MRI). The CEST image contrast depends on physical and physiological parameters that characterize the microenvironment such as temperature, pH, and metabolite concentration. However, CEST imaging in vivo is a c...

Kinematic equations for the motion of slowly propagating, weakly curved fronts in bistable media are derived. The equations generalize earlier derivations where algebraic relations between the normal front velocity and its curvature are assumed. Such relations do not capture the dynamics near nonequilibrium Ising-Bloch (NIB) bifurcations, where transitions between counterpropagating Bloch front...

Incontinentia Pigmenti (IP) is a rare X-linked dominant disorder with skin, eye, central nervous system (CNS) and tooth abnormalities. According to the reported cases, it is estimated that there have been nearly 900-1200 affected individuals. In this article, the literature is reviewed and a case of IP with characteristic skin lesions and optic atrophy is presented.

We report a female infant born to a mother with incontinentia pigmenti (IP) and a father with haemophilia A, who manifests both disorders. Analysis of peripheral blood DNA from the infant, her mother, and two female relatives with IP showed a highly skewed pattern of X inactivation. Random patterns were observed in the infant's two sisters, who do not have IP and have normal carrier activity of...

Wideband suppression of zero order and relevant strongly asymmetric transmission can be obtained in photonic crystal gratings that are made of linear isotropic materials and show the broken structural (axial) symmetry, even if zero diffraction order may be coupled to a Floquet-Bloch (FB) wave at the incidence and exit interfaces. The studied mechanism requires that the peculiar diffractions at ...

IP Address blacklisting [1, 2] works by storing a list of the origin of known spam and then ignoring further email sent from that IP address, under the assumption it is also spam. This approach has two problems: spammers are able to circumvent it by regularly switching IP addresses, and after spam has been sent from an IP address hijacked by a spammer, email sent by the unsuspecting computer us...

In the United States 1.4 million children were maltreated in 1988, resulting in an estimated 2000 to 5000 deaths. Largely due to the rising awareness and sensitivity to the horrors of child abuse, the number of deaths declined to approximately 1500 in 1993. Guidelines have been published to aid in the identification and management of child maltreatment, and reporting of all suspicious cases is ...

Basiri MD Tel: +98 9188121848 Email: [email protected] Abstract Objective Incontinentia Pigmenti (IP) (Bloch_Sulzberg syndrome) is a rare neurocutaneous syndrome characterized by multisystemic involvement that is prenatally lethal in the majority of affected males and shows great clinical variability when expressed in women. The diagnosis of IP is performed based o...

• A network service provider wants to keep track of the traffic going through the network, in order to detect unusual patterns, which may be a sign of malicious activity. For example, an increased traffic to a particular IP address may suggest a Denial of Service attack is under way. Such unusual traffic patterns should be detected almost in real time, however the throughput of the network is s...
