In recent technology nodes,reliability is increasingly considered a part of the standard design flow to be taken into account at all levels of embedded systems *** traditional fault simulation techniques based on low-level models at gate-and register transfer-level offer high accuracy,they are too inefficient to properly cope with the complexity of modern embedded ***,they do not allow for early exploration of design alternatives when a detailed model of the whole system is not yet available,which is highly required to increase the efficiency and quality of the design ***-level models that combine the simulation efficiency of high abstraction models with the accuracy of low-level models are therefore essential to efficiently evaluate the impact of physical defects on the *** paper proposes a methodology to efficiently implement concurrent multi-level fault simulation across gate-and transaction-level models in an integrated simulation *** leverages state-of-the-art techniques for efficient fault simulation of structural faults together with transaction-level *** combination of different models allows to accurately evaluate the impact of faults on the entire hardware/software system while keeping the computational effort ***,since only selected portions of the system require low-level models,early exploration of different design alternatives is efficiently *** results obtained from three case studies are presented to demonstrate the high accuracy of the proposed method when compared with a standard gate/RT mixed-level approach and the strong improvement of simulation time which is reduced by four orders of magnitude in average.

AIM: To value whether omeprazole could induce the healing of diS and regression of symptoms in patients with DGER. METHODS: We enrolled 15 symptomatic patients with a pathological esophageal 24-h pH-metry and bilimetry. Patients underwent endoscopy and biopsies were taken from the distal esophagus. Specimens were analyzed at histology and transmission electron microscopy (TEM). Patients were treated with omeprazole 40 mg/d for 3 mo and then endoscopy with biopsies was repeated. Patients with persistent heartburn and/or with an incomplete recovery of diS were treated for 3 more months and endoscopy with biopsies was performed. RESULTS: Nine patients had a non-erosive reflux disease at endoscopy (NERD) while 6 had erosive esophagitis (ERD). At histology, of the 6 patients with erosive esophagitis, 5 had mild esophagitis and 1 moderate esophagitis. No patients with NERD showed histological signs of esophagitis. After 3 mo of therapy, 13/15 patients (86.7%,PdiS and disappearance of heartburn. Of the 2 patients treated for 3 more months, complete recovery of diS and heartburn were achieved in one. CONCLUSION: Three or 6 mo of omeprazole therapy led to a complete regression of the ultrastructural esophageal damage in 86.7% and in 93% of patients with DGER, NERD and ERD respectively. The ultrastructural recovery of the epithelium was accompanied by regression of heartburn in all cases.

Green growth cannot succeed without significant changes in the education system and the closely related social division of labor. This paper combines historical evidence and a game-theoretic analysis to study the relation between vocational education and green growth. It is found that a low-vocation and a high-vocation equilibrium can be distinguished in the interplay between education and labor markets, and that a high-vocation equilibrium is better suited for green growth. A t the present stage of development, there are tendencies in both directions in China. Therefore, China has the possibility to successfully implement a green growth strategy by developing a strong vocational education with Chinese characteristics.

We theoretically investigate the electromagnetic response of a novel class of multilayered metamaterials obtained by alternating graphene sheets and dielectric layers,the whole structure not exhibiting a plane of reflection symmetry along the stacking *** show that the electromagnetic response of the structure is characterized by a magneto-electric coupling described by an effective chiral *** the intrinsic tunability of graphene–light coupling,we prove that one can tune both the dielectric and the chiral electromagnetic response by varying the graphene chemical potential through external voltage gating.

The electric field induced Lyman-a emission diagnostic aims to provide a non intrusive and precise measurement of the electric field in plasma, using a beam of hydrogen atoms prepared in the metastable 2s state. The metastable particles are obtained by means of a proton beam extracted from a hydrogen plasma source, and neutralised by interaction with vaporised caesium. When a 2s atom enters a region where an electric field is present, it undergoes a transition to the 2p state （Stark mixing）. It then quickly decays to the ground level, emitting Lyman-a radiation, which is collected by a photomultiplier. The 2s → 2p transition rate is proportional to the square of the magnitude of the electric field, and depends on the field oscillation frequency （with peaks around l GHz）. By measuring the intensity of the Lyman-a radiation emitted by the beam it is possible to determine the magnitude of the field in a defined region. In this work, an analysis of the behaviour of the diagnostic under static or radiofrequency electric field is presented. Electric field simulations obtained with a finite element solver of Maxwell equations, combined with theoretical calculations of the Stark mixing transition rate, are used to develop a model for the interpretation of photomultiplier data. This method shows good agreement with experimental results for the static field case, and allows to measure the field magnitude for the oscillating case.

Legged robots relying on dry adhesives for vertical climbing are required to preload their feet against the wall to increase contact surface area and consequently maximize adhesion force. Preloading a foot causes a redistribution of forces in the entire robot, including contact forces between the other feet and the wall. An inappropriate redistribution of these forces can cause irreparable detachment of the robot from the vertical surface. This paper investigates an optimal preloading and detaching strategy that minimizes energy consumption, while retaining safety, during locomotion on vertical surfaces. The gait of a six-legged robot is planned using a quasi-static model that takes into account both the structure of the robot and the character- istics of the adhesive material. The latter was modelled from experimental data collected for this paper. A constrained optimi- zation routine is used, and its output is a sequence of optimal posture and motor torque set-points.
