CAS to Re-orient Its Research on High-energy Physics & Advanced Accelerator Facilities

After a two-year-long investigation and considerable research, CAS (Chinese Academy of Sciences) recently defined its long-term and medium strategic targets for the development of high-energy physics and advanced accelerator facilities: ·Making a major renovation on the Beijing Electron-Positron Collider (BEPC) so that it is capable of accomplishing top-ranking research results in charmphysics;

Physical scientists research biomedicine: a call for caution

It is noticeable that nowadays there are more and more scientists with physical science or engineering background working on or started to work on biomedical projects, but rarely vice versa. This reflects the multi-discipline nature of some projects, however, also at least partially can be explained that biomedical research is seen as trendy, fundable, and likely to get more citations and with results more publishable in high impact journals （1,2）. It is also apparent with some publications and lectures that not all these physical scientists/engineers are well-prepared to work on projects which do not align with their own expertise. Some studies are against very basic principles of pharmacology or biology, while others try to solve medical problems which do not exist clinically. I reviewed a number of submissions including a few from prestigious American universities to Nature journals which made no sense with the study design. Much of manpower and financial resource are being wasteful spent. There are also examples of clinical trials which were ill-planned right from the start and in the end only causing much inconvenience to patients to say at the least. In addition, ample examples exist where experienced physical scientists worked with inexperienced medical scientists and resulted in avoidable failures.

Teaching for physical literacy: Implications to instructional design and PETE

Physical education teachers play an important role in helping students＇ development of the motor skills needed to be physically literate individuals. Research suggests that teacher made instructional design decisions can lead to enhanced motor skill learning. After presenting a model of evidence-based research this paper presents information that will help teachers plan and execute lessons designed to improve students＇ motor skills. Variables that impact motor skill learning in physical education including time, type of practice, content, presentation and organizational strategies, and student skill level are presented and discussed. A brief section on student attitudes, their relation to motor skill learning and to physical literacy is included. Motor skills are needed for physically literate people to enjoy lifelong physical activity. Physical education teachers and the decisions they make contribute to students＇ learning and whether the goal of physical literacy is met.

Physical Model of Drying Shrinkage of Recycled Aggregate Concrete

We prepared concretes（RC0, RC30, and RC100） with three different mixes. The poresize distribution parameters of RAC were examined by high-precision mercury intrusion method（MIM） and nuclear magnetic resonance（NMR） imaging. A capillary-bundle physical model with random-distribution pores（improved model, IM） was established according to the parameters, and dry-shrinkage strain values were calculated and verified. Results show that in all pore types, capillary pores, and gel pores have the greatest impacts on concrete shrinkage, especially for pores 2.5-50 and 50-100 nm in size. The median radii are 34.2, 31, and 34 nm for RC0, RC30, and RC100, respectively. Moreover, the internal micropore size distribution of RC0 differs from that of RC30 and RC100, and the pore descriptions of MIM and NMR are consistent both in theory and in practice. Compared with the traditional capillary-bundle model, the calculated results of IM have higher accuracy as demonstrated by experimental verifi cation.
