Self-aligned double injection-function contact mitigating short channel effects in sub-micron channels of solution processed indium gallium zinc oxide

We propose and demonstrate self-aligned Double Injection Function Thin Film Transistor (DIF-TFT) architecture that mitigates short channel effects in 200nm channel on a non-scaled insulator (100nm SiO2). In this conceptual design, a combination of an ohmic-like injection contact and a high injection-barrier metal allows maintaining the high ON currents while suppressing the drain-induced barrier lowering. Using an industrial 2D device simulator (Sentaurus), we propose two methods to realize the DIF concept and we use one of them to experimentally demonstrate a DIF-TFT based on solution processed IGZO. Using molybdenum as the ohmic contact and platinum as the high injection barrier, we compare three transistor’s source-contacts: ohmic, Schottky, and double injection function. The fabricated DIF-TFT exhibits saturation at sub 1V drain bias with only about a factor of 2 loss in ON current compared to the ohmic contact.

Multi-objective Optimization of Data Placement in a Storage-as-a-Service Federated Cloud

Cloud federation enables service providers to collaborate to provide better services to customers. For cloud storage services, optimizing customer object placement for a member of a federation is a real challenge. Storage, migration, and latency costs need to be considered. These costs are contradictory in some cases. In this article, we modeled object placement as a multi-objective optimization problem. The proposed model takes into account parameters related to the local infrastructure, the federated environment, customer workloads, and their SLAs. For resolving this problem, we propose CDP-NSGAII IR , a Constraint Data Placement matheuristic based on NSGAII with Injection and Repair functions. The injection function aims to enhance the solutions’ quality. It consists to calculate some solutions using an exact method then inject them into the initial population of NSGAII. The repair function ensures that the solutions obey the problem constraints and so prevents from exploring large sets of unfeasible solutions. It reduces drastically the execution time of NSGAII. Experimental results show that the injection function improves the HV of NSGAII and the exact method by up to 94% and 60%, respectively, while the repair function reduces the execution time by an average of 68%.

Legitimacy and procedural justice: how might stratospheric aerosol injection function in the public interest?

The success of stratospheric aerosol injection (SAI) in limiting global heating requires the inclusion and maintenance of the political ideals of legitimacy and procedural justice. Without them, the prospects are slim that this institution can be developed and operated in the public interest in such a way that it will protect and promote social well-being by minimising climate-related harm. Long term legitimacy and procedural justice are crucial to several sensitive features of SAI. They relate to openness, inclusivity and independence, in dealing both with external issues of concern to stakeholders representing the general public and with internal issues concerning agents directly involved in SAI. This article begins by outlining notions of legitimacy and procedural justice, and the criteria appropriate for SAI. Then it investigates how the moral indications provided by the related standards might ensure that SAI is not distorted in such ways that it serves the selfish interests of private parties. Finally, the article outlines two governance recommendations for ensuring that legitimacy and procedural justice in SAI are achieved and maintained over time, so that it can work continuously in the public interest.

On a Periodic Capital Injection and Barrier Dividend Strategy in the Compound Poisson Risk Model

In this paper, we assume that the reserve level of an insurance company can only be observed at discrete time points, then a new risk model is proposed by introducing a periodic capital injection strategy and a barrier dividend strategy into the classical risk model. We derive the equations and the boundary conditions satisfied by the Gerber-Shiu function, the expected discounted capital injection function and the expected discounted dividend function by assuming that the observation interval and claim amount are exponentially distributed, respectively. Numerical examples are also given to further analyze the influence of relevant parameters on the actuarial function of the risk model.

Evaluation of endoscopic submucosal dissection using a new endosurgical knife DN-D2718B: a first clinical feasibility study

Background and study aims Endosurgical devices with injection function have been reported to decrease endoscopic submucosal dissection (ESD) operation times for experts, but the efficacy of these devices for inexperienced endoscopists is unclear. The aim of this study was to evaluate the feasibility of ESD using a novel ESD knife (DN-D2718B). Patients and methods This is a single-center prospective pilot clinical feasibility study. Patients diagnosed with superficial gastrointestinal neoplasms were enrolled. A pre-specified group of ESD trainees with ESD experience on a porcine gastric model and fewer than 30 cases of ESD in their selected fields performed ESD under expert supervision, using the DN-D2718B. En bloc resection rates, R0 resection rates, procedure times, and incidence of intra-operational/post-operational adverse events were assessed. Results Between June 2015 and January 2016, 13 esophageal, 27 gastric, and 14 colorectal ESD cases were performed per-protocol with mean resection speeds of 10.2, 12.0, and 15.5 mm2/min, respectively. There were no intra-operational complications. Conclusion ESD with this novel knife is feasible even when performed by non-experts.

Medical Auto-Injector Design

A kind simple structure and convenient operation of automatic injector is designed in the paper. It can be placed on the desk with the friendly interface. Its core components are AT89C51 and stepping motor. SCM can be controlled by the corresponding key to send the logic control signal through software programming. In order to achieve the automatic injection function under different speeds at 20 ml, 30 ml and 50 ml liquid level, automatic injector is drove by the different statuses of stepping motor, such as open and stop, acceleration and deceleration, turning and reversal, etc. For driving stepping motor more better, the drive chip ULN2003 is used. The speed, the turning direction and the injection dose of stepping motor is displayed with LED. It realizes the well-proportioned injection, avoids the error caused by artificial operation and uncertainty, and reduces the pressure of the medical staff.
