Our purpose is to compare cobinamide to hydroxocobalamin in reversing cyanide (CN)-induced physiologic effects in an animal model using diffuse optical spectroscopy (DOS). Cyanide poisoning is a major threat worldwide. Cobinamide is a novel molecule that can bind two molecules of cyanide, has a much higher binding affinity than hydroxocobalamin, and is more water soluble. We investigated the ab...

Memory DoS attacks are Denial of Service (or Degradation of Service) attacks caused by contention for hardware memory resources. In cloud computing, these availability breaches are serious security threats that occur despite the strong memory isolation techniques for Virtual Machines (VMs), enforced by the software virtualization layer. The underlying hardware memory layers are still shared by ...

the angiotensin 1-7 (ang 1-7), is abundantly produced in kidneys and antagonizes the function of angiotensin ii through mas receptor (masr) or other unknown mechanisms. in the current study, the role of masr and steroid hormone estrogen on renal blood flow response to ang 1-7 administration was investigated in ovariectomized (ov) female rats. ov female wistar-rats received estradiol (500 µg/kg/...

Malicious intruders may launch as many invalid requests as possible without establishing a server connection to bring server service to a standstill. This is called a denial-of-service (DoS) or distributed DoS (DDoS) attack. Until now, there has been no complete solution to resisting a DoS/DDoS attack. Therefore, it is an important network security issue to reduce the impact of a DoS/DDoS attac...

The immune response of mice subcutaneously immunized with two lectins from Artocarpus heterophyllus seeds, artocarpin and jacalin, and their possible modulatory effect on antibody synthesis of mice immunized with an unrelated antigen, were studied. Both lectins induced specific synthesis of antibodies, irrespective of their immunizing dose. Concerning the modulatory effect on the synthesis of a...

Global System for Mobile communications (GSM) is a popular mobile communications network. Short Message Service (SMS) is an easily adopted person-to-person communications technology for mobile devices. The GSM architecture allows for the insertion of mass application-generated SMS messages directly into the network infrastructure. This is achieved through a SMS Mobile Switching Centre (SMSC) us...

In recent years, Wireless Voice over IP (WVoIP) has been one of the most popular telecommunication technologies. Quality of Service (QoS) and security are two important issues which determine the success of WVoIP. WVoIP QoS issues have been extensively studied. However, security issues of WVoIP are rarely addressed. In this paper, we study one important WVoIP security issue of Denial of Service...

Denial of Service (DoS) attacks can be easily launched in Wireless Sensor Networks (WSNs). Due to their resource constraints, namely limited energy, memory and bandwidth, WSNs are especially vulnerable to DoS attacks. This paper addresses a particular class of DoS attacks that overwhelm resources along a multihop data delivery path. Since WSNs are typically tree-structured, then a DoS attack on...

This paper addresses the security issue of networked control systems (NCSs) under DoS attacks. According to the level of attacks, DoS attacks are classified into two types: weak attacks and strong attacks. A recursive networked predictive control (RNPC) method based on round-trip time delay is proposed to compensate for the adverse effects introduced by the weak DoS attacks as well as the netwo...

The density of states (DOS) of electrons in two-dimensional (2D) quantum wells and the broadening of Landau levels (LL's) is evaluated. The electrons are assumed to interact with screened, charged impurities located at random in the material. The random location of the impurities leads to a disordered environment seen by the electrons. The screening of the impurities by the 2D electron gas is e...
