In this paper we analyze a new class of pulsing denialof-service (PDoS) attacks that could seriously degrade the throughput of TCP flows. During a PDoS attack, periodic pulses of attack packets are sent to a victim. The magnitude of each pulse should be significant enough to cause packet losses. We describe two specific attack models according to the timing of the attack pulses with respect to ...

This paper addresses the important problem of detecting pulsing denial of service (PDoS) attacks which send a sequence of attack pulses to reduce TCP throughput. Unlike previous works which focused on a restricted form of attacks, we consider a very broad class of attacks. In particular, our attack model admits any attack interval between two adjacent pulses, whether deterministic or not. It al...

The emergence of three-dimensional human organoids has opened the door for development patient-derived cancer organoid (PDO) models, which closely recapitulate parental tumor tissue. mainstays preclinical modeling include in vitro cell lines and xenografts, but these models lack cellular heterogeneity seen tumors. Moreover, xenograft establishment is resource time intensive, rendering difficult...

Pulsing Denial of Service (PDoS) is a type of DoS attack. Its attacking behavior is intermittent rather than constant, which helps it avoid being detected. In this paper, an adaptive detection method is proposed for source-end detection of PDoS attacks. It has three distinctive features: (i) its detection statistic is based on the discrepancy in the aggregated outbound and inbound packets; (ii)...

objective(s): first-principles calculations have been carried out to investigate the interaction of aspirin molecule with nitrogen-doped tio2 anatase nanoparticles using the density functional theory method in order to fully exploit the biosensing capabilities of tio2 particles. methods: for this purpose, we have mainly studied the adsorption of the aspirin molecule on the fivefold coordinated ...

Internet of Things (IoT) support for smart city systems improves service scales by ignoring various user congestion. People are looking different security features reliable and robust applications. Here, the Permanent Denial Service (PDoS) problem arises from improper identification. This article introduces Service-Reliant Application Authentication (SRAA) to prevent PDoS attacks in a area city...

In this paper, the interfacial stabilities of six different stacking interface configurations Ni(100)/Ni3Al(100) eutectic structures with AlNi termination and Ni are calculated by using first-principles methods. The adhesion work energy indicate that “Center” site more stable than “Top” “Bridge” models. partial density states (PDOS) charge difference confirm bonding characteristic Ni-terminated...

Block encoding lies at the core of many existing quantum algorithms. Meanwhile, efficient and explicit block encodings dense operators are commonly acknowledged as a challenging problem. This paper presents comprehensive study rich family operators: pseudo-differential (PDOs). First, scheme for generic PDOs is developed. Then we propose more with separable structure. Finally, demonstrate an alg...

The Mg(BiO2)2 is the orthorhombic crystal system acting as semiconductor in electric devices. To evaluate electronic band structures, the total density of state (TDOS) and the partial density of state (PDOS), Generalized Gradient Approximation (GGA) based on the Perdew–Burke–Ernzerhof (PBE0) was used for Mg(BiO2)2. The band gap was recorded at 0.959 eV, which is supported by a good semiconducto...
