Background The cryogenic control system of BEPCII has been in stable operation for more than 10 years,providing techni-cal support for the generation of cryogenic environments.The core hardware of the cryogenic control system is composed of PLC and VME controller,and the operating software includes PLC commercial software and EPICS.However,some hardware and software are obsolete.Purpose An upgrade prototype of the cryogenic control system is designed and built to study the compatibility contradiction between software and hardware,and ensure the long-term stable operation of cryogenic system.Method Keep the hardware architecture,upgrade the software and hardware modules of PLC and VME respectively,and test the system compatibility.Conclusion The upgrading prototype of the cryogenic control system solves the problem of software and hardware compat-ibility,and makes it possible to achieve a seamless and smooth upgrade of the cryogenic control system in the future.

Most of the light water reactor power plants now operating or under construction use pressurized-water reactor (PWR). They are suffering of relatively low thermal efficiency which is around 33%. This would not only have a negative impact economically but also incurs environmental burden in terms of thermal pollution. In this paper, nuclear steam supply system of a typical PWR has been taken into consideration using 1000 MWe Bushehr nuclear power plant (BNPP) data. It is shown thermal efficiency could conceivably be increased by superheating live steam with natural gas up to around 40%, competing with similar fossil-fueled power plants. It is further shown that fuel cost (natural gas) as low as 0.12 Cent/MWe, extra power generated is feasible.

Recommendations for managing clinically localized prostate cancer are structured around clinical risk criteria,with prostate biopsy(PB)Gleason score(GS)being the most important factor.Biopsy to radical prostatectomy(RP)specimen upgrading/downgrading is welldescribed,and is often the ratio nale for costly imaging or genomic studies.We prese nt simple,no-cost an a lyses of clinical parametersto predict which GS 6 and GS 8 patients will change to GS 7 at prostatectomy.From May 2006 to December 2012,1590 patientsunderwent robot-assisted radical prostatectomy(RARP).After exclusions,we identified a GS 6 cohort of 374 patients and a GS 8cohort of 91 patients.During this era,>1000 additional patients were enrolled in an active surveillanee(AS)program.For GS 6,265(70.9%)of 374 patients were upgraded,and the cohort included 183(48.9%)patients eligible for AS by the Prostate Cancer ResearchInternational Active Surveillance Study(PRIAS)standards,of which 57.9%were upgraded.PB features that predicted a>90%chanceof upgrading included≥7 cores positive,maximum foci length≥8 mm in any core,and total tumor involvement≥30%.For GS 8,downgrading occurred in 46(50.5%),which was significantly higher for single core versus multiple cores(80.4%vs 19.6%,P=0.011).Biochemical recurre nee(BCR)occurred in 3.4%of GS 6 upgraded versus 0%non upgraded,and in GS 8,19.6%downgraded versus42.2%nondown graded.In coun seling men with clin ically localized prostate can cer,the odds of GS cha nge should be presented,andcertain men with high-volume GS 6 or low-volume GS 8 can be counseled with GS 7-based recommendations.

As the indispensable component of accelerator, the performance of power supply system is directly related withthe performance of accelerator. In order to obtain a high quality beam and improve the operation efficiency ofHIRFL (Heavy Ion Research Facility in Lanzhou), the upgrade work of the existing equipments is never stopped inthe power supply system. In 2014, the work was mainly focused on improving the performance of CSRe (coolingstorage experimental ring) and RIBLL 2 (Radioactive Ion Beam Line in Lanzhou).

To improve the control efficiency of Superconducting Electron Cyclotron Resonance Ion source (SECRAL) forHeavy Ion Research Facility in Lanzhou (HIRFL), a upgrade version of control system for SECRAL system wasdesigned and set up in September 2014. The control software package is developed by Visual C++, which is ableto control and monitor all of the equipment for the SECRAL system with about 130 parameters. The previousanalog powers are discarded and four digital high powers are used newly at high voltage platform, which containtwo stove powers, a bias voltage power, and a sputter power. Moreover, four servo motors are added newly, whichcontain work gas, support gas, bias voltage, and sputter voltage. Reflecting vacuum value picturesquely, we plot agraph of inject vacuum, elicit vacuum, and beam vacuum against time. In order to prevent the misoperation whichmay cause the quench of the superconducting magnet, alarm and interlock-protection functions are added to thesoftware and hardware. Simultaneously, added stretch buttons are able to void accidental on-click that might bringabout serious outcome.
