When I met the difficulties in the statistical analysis of the doctoral thesis questionnaire, I couldn't find a clue. Finally, I saw Dr.Tong's assistance in the statistical analysis of the thesis questionnaire on qimo.com. With the assistance of the doctor, I got the results smoothly. Thank Dr.Tong for his assistance in the statistical analysis of the thesis questionnaire, which solved my urgent problem.

Previously, a local statistics company in Hong Kong was entrusted, but it failed to do a good job in medical statistics. In my anxiety, I saw the doctor teacher of Dr.Tong statistics company provide statistical running and guidance, and sent the data and requirements to the doctor teacher. With the efforts of the doctor teacher, the analysis results were successfully made. I feel that Taiwan's statistics companies are more professional and the fees are reasonable.

When I met the difficulties in the statistical analysis of the pre-test and post-test of the thesis questionnaire, I couldn't solve them all the time. On Qimo, I saw that the doctoral teacher of Dr.Tong statistics company provided the tutoring service of thesis statistics, and sent the information and requirements to the doctoral teacher. With the help and guidance of the teacher, I got the results. Thank you very much for the tutoring service of the doctoral teacher of Dr.Tong statistics company There are two difficulties.

It's difficult to analyze Stata data in accounting papers. On Yahoo Qimo, I saw the doctor teacher of Dr.Tong statistics company provide Stata statistical running guidance. The data and requirements were sent to the doctor's teacher. Under the guidance of the doctor's teacher, the Stata code was successfully designed, and the analysis results were also run out. I would like to thank the doctor's teacher of Dr.Tong statistics for his high level guidance and assistance.

Educational papers have quantitative statistics, which is a bit difficult! Helpless, I saw on Yahoo Qimo that Dr. and postdoctoral teachers from Dr.Tong Statistics Company provide doctoral thesis statistics and counseling services. I sent the questionnaire and sample data to the doctor, and with the guidance and assistance of the doctor, I successfully obtained the results and graduated. I am very grateful for the professional guidance of the doctor and postdoctoral teacher from Dr.Tong Statistics Company. The technical expertise, reliable quality, and reasonable fees have saved me a lot of trouble.

A "superatomic" material has become the fastest known semiconductor and could increase the speed of computer chips hundreds or thousands of times.Recently, Milan Delor and colleagues at Columbia University discovered the faster and more efficient semiconductor, which is made of rhenium, selenium and chlorine, in a chemical formula called Re6Se8Cl2.Related papers are published in Science.

In fact, particles called excitons move slower in this material than electrons do in silicon, but crucially, they move in a straight line with arrows, so they move much faster at similar distances.
Silicon semiconductors used in computer-chip transistors rely on electronic streams to transmit data, but these particles tend to scatter wildly, waste energy in the form of heat, and slow data from A to B.
If transistors using excitons instead of electrons are made from the new material, they can move from one side of the transistor to the other without scattering, which will make them 100 to 1,000 times faster from A to B than electrons in silicon wafers.
With the help of new materials, in principle, transistors can switch at hundreds of GHz or even terahertz."We predict that the performance improvement will be significant," Delor said.”
Delor says it will take decades to use the material for computer chips.Engineers will take decades to perfect silicon wafer manufacturing, and switching to new materials will essentially get them back to square one.Rhenium is one of the rarest elements in the Earth's crust, while silicon is the second richest, so chips made using Re6Se8Cl2 could be used in spacecraft and quantum computers.
