Abstract The advanced integrated circuits have been widely used in various situations including the Internet of Things, wireless communication, etc. But its manufacturing process exists unreliability, so cryptographic chips must be rigorously tested. Due to scan testing provides high test coverage, it is applied to the testing of cryptographic integrated circuits. However, while providing good controllability and observability, it also provides attackers with a backdoor to steal keys. In the text, a novel protection scheme is put forward to resist scan-based attacks, in which we first use the responses generated by a strong physical unclonable function circuit to solidify fuse-antifuse structures… More >

Abstract We study nonhomogeneous systems of linear conformable fractional differential equations with pure delay. By using new conformable delayed matrix functions and the method of variation, we obtain a representation of their solutions. As an application, we derive a finite time stability result using the representation of solutions and a norm estimation of the conformable delayed matrix functions. The obtained results are new, and they extend and improve some existing ones. Finally, an example is presented to illustrate the validity of our theoretical results. More >

Abstract Fixed-time synchronization (FTS) of delayed memristor-based neural networks (MNNs) with discontinuous activations is studied in this paper. Both continuous and discontinuous activations are considered for MNNs. And the mixed delays which are closer to reality are taken into the system. Besides, two kinds of control schemes are proposed, including feedback and adaptive control strategies. Based on some lemmas, mathematical inequalities and the designed controllers, a few synchronization criteria are acquired. Moreover, the upper bound of settling time (ST) which is independent of the initial values is given. Finally, the feasibility of our theory is attested by simulation examples. More >

Abstract In 2020, the reported cases were 0.12 million in the six regions to the official report of the World Health Organization (WHO). For most children infected with leprosy, 0.008629 million cases were detected under fifteen. The total infected ratio of the children population is approximately 4.4 million. Due to the COVID-19 pandemic, the awareness programs implementation has been disturbed. Leprosy disease still has a threat and puts people in danger. Nonlinear delayed modeling is critical in various allied sciences, including computational biology, computational chemistry, computational physics, and computational economics, to name a few. The time delay effect in treating leprosy… More >

Abstract Concomitant acute epidural hematoma (EDH) and subdural hematoma (SDH) is a rare finding, and its bilateral onset has not yet been reported in literature. We present the first report of a patient affected by post-traumatic concomitant EDH and SDH, with the contralateral, delayed onset of another, associated with meningioma previously treated with gamma knife. A 60-year-old female patient with a history of simple focal seizures with motor symptoms and well-controlled by drugs since childhood, arterial hypertension, and incidental diagnosis of multiple meningiomas was referred to our department after falling down the stairs. Initially, the patient was prescribed gamma knife treatment… More >

Abstract Radiotherapy (RT) is an important treatment for non-small cell lung cancer (NSCLC). However, the major obstacles to successful RT include the low radiosensitivity of cancer cells and the restricted radiation dose, which is given without damaging normal tissues. Therefore, the sensitizer that increases RT efficacy without dose escalation will be beneficial for NSCLC treatment. Eurycomalactone (ECL), an active quassinoid isolated from Eurycoma longifolia Jack, has been demonstrated to possess anticancer activity. In this study, we aimed to investigate the effect of ECL on sensitizing NSCLC cells to X-radiation (X-ray) as well as the underlying mechanisms. The results showed that ECL… More >

Abstract Integrated energy system optimization scheduling can improve energy efficiency and low carbon economy. This paper studies an electric-gas-heat integrated energy system, including the carbon capture system, energy coupling equipment, and renewable energy. An energy scheduling strategy based on deep reinforcement learning is proposed to minimize operation cost, carbon emission and enhance the power supply reliability. Firstly, the low-carbon mathematical model of combined thermal and power unit, carbon capture system and power to gas unit (CCP) is established. Subsequently, we establish a low carbon multi-objective optimization model considering system operation cost, carbon emissions cost, integrated demand response, wind and photovoltaic curtailment,… More >

Abstract This study was designed to investigate the protective effects of Astaxanthin (AST) in rats with diabetes mellitus (DM) induced by streptozotocin. SD rats were divided into control group (n = 5, only received normal saline), DM group (n = 8) and AST + DM group (n = 8; AST: 50 mg/kg/day). DM rats were induced by intraperitoneal injection of streptozocin (STZ, 65 mg/kg). Blood glucose level and body weight were determined at weeks 0, 2, 4, 6 and 8, respectively. At week 8, kidney function was determined, together with expression of P53 and dynamin-related protein-1 (Drp1) by Western blot analysis… More >

Abstract This paper deals with the fixed-time adaptive time-varying matrix projective synchronization (ATVMPS) of different dimensional chaotic systems (DDCSs) with time delays and unknown parameters. Firstly, to estimate the unknown parameters, adaptive parameter updated laws are designed. Secondly, to realize the fixed-time ATVMPS of the time-delayed DDCSs, an adaptive delay-unrelated controller is designed, where time delays of chaotic systems are known or unknown. Thirdly, some simple fixed-time ATVMPS criteria are deduced, and the rigorous proof is provided by employing the inequality technique and Lyapunov theory. Furthermore, the settling time of fixed-time synchronization (Fix-TS) is obtained, which depends only on controller parameters… More >

Abstract Crumb rubber powder is a successfully used renewable material obtained from waste tire rubber, which has been incorporated into paving asphalt since the 1930s due to its good resistance to deformation and fatigue as well as its eco-friendly performance. In this study, carbon nanotubes and nano silica were incorporated into the terminal blend crumb rubber modified asphalt technology to remedy the issues of excessive desulfurization and degradation of ground tyre rubber with this technology. The mechanism behind the high temperature delayed elastic properties of the crumb rubber-nano-asphalt hybrids was experimentally investigated based on discrete relaxation spectrum. Development of the discrete… More >
