Eletrodo de diamante foi usado para avaliar a interação dos nucleotídeos guanosina monofosfato (GMP) e adenosina monofosfato (AMP) com os pesticidas clorpirifós, metamidofós e monocrotofós. Observaram-se alterações nas correntes e potenciais de picos dos voltamogramas dos nucleotídeos na presença dos pesticidas dependendo da concentração de pesticida (de 5,0 × 10 a 5,0 × 10 mol L) e do tempo de...

Article history: Received 15 February 2015 Received in revised form 2 December 2015 Accepted 3 December 2015 Available online 23 March 2016 The modeling of the transient subgap density of states (DOS) for the investigation of trap densities in the oxidebased thin-film transistors is proposed. The study is based on both transient measurements and physical modeling. In history, the subgap DOS mod...

Public reporting burden for the collection of information is estimated to average 1 hour per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information. Send comments regarding this burden estimate or any other aspect of this collection of information, including s...

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...

Diffuse optical spectroscopy (DOS) of breast tissue provides quantitative, functional information based on optical absorption and scattering properties that cannot be obtained with other radiographic methods. DOS-measured absorption spectra are used to determine the tissue concentrations of deoxyhemoglobin (Hb-R), oxyhemoglobin (Hb-O2), lipid, and water (H2O), as well as to provide an index of ...

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...
