A smart meta-superconductor Bi(Pb)SrCaCuO (B(P)SCCO) may increase the critical transition temperature (TC) of B(P)SCCO by electroluminescence (EL) energy injection inhomogeneous phases. However, amplitude ?TC (?TC=TC?TC,pure) TC is relatively small. In this study, a with different matrix sizes was designed. Three kinds raw materials particle were used, and series Y2O3:Sm3+, Y2O3, Y2O3:Eu3+, Y2O...

Thyroid and breast cancers (TC, BC) are common female malignant tumors worldwide. Studies suggest that TC patients have a higher BC risk, and vice versa. However, it has not been investigated quantitatively if there is an association between the space-time TC and BC incidence distributions at the population level. This work aims to answer this question. 5358 TC and 8784 BC (female) cases were d...

The nitro group of 2-nitroimidazole (NIM) enters the tumor cells and is bioreductively activated and fixed in the hypoxia cells. 1,4,8,11-tetraazacyclotetradecane (N4) has shown to be a stable chelator for (99m)Tc. The present study was aimed to develop (99m)Tc-cyclam-2-nitroimidazole ((99m)Tc-N4-NIM) for tumor hypoxia imaging. N4-NIM precursor was synthesized by reacting N4-oxalate and 1,3-dib...

BACKGROUND AND THE PURPOSE OF THE STUDY Technetium-99m is the major radionuclide used in the world and mainly is provided by fission product. However extensive research has been conducted on the use of accelerators for production of (99m)Tc. This investigation reports the production of (99m)Tc radioisotope using cyclotrons and the preparation, quality control and biodistribution studies of four...

I briefly review several key issues in understanding the cuprate superconductors from the point of view of doped-Mott-insulator. Then I present an effective low-energy theory and show that the phase diagram of such a model includes an anti-ferromagnetic (AF) phase, a superconducting state, and a pseudogap phase at low doping and low temperature, consistent with the experimental one. The dual to...

How to enhance the superconducting critical temperature (Tc) has been a primary issue since the discovery of superconductivity. The highest Tc reported so far is 166 K in HgBa2Ca2Cu3O8+δ (Hg1223) at high pressure of 23 GPa, as determined with the reduction onset, but not zero, of resistivity. To clarify the possible condition of the real maximum Tc, it is worth revisiting the effects of pressur...

We report first-principles calculations of the structures and properties of technetium nitride phases within the framework of gradient-corrected density functional theory. Specifically, we have investigated the possible existence of hexagonal Tc(3)N and Tc(2)N subnitrides, following the recent discovery of Re nitrides analogues synthesized directly from the elements. These novel Tc subnitride p...

UNLABELLED Reliable assessment of hepatic function during liver regeneration is crucial after liver surgery or liver transplantation. (99m)Tc-galactosyl human serum albumin ((99m)Tc-GSA) scintigraphy, (99m)Tc-mebrofenin hepatobiliary scintigraphy (HBS), the indocyanine green (ICG) clearance test, and the galactose elimination capacity (GEC) are common quantitative liver function tests. However,...

(99m)Tc-HYNIC-annexin A5 can be considered as a benchmark in the field of apoptosis imaging. However, (99m)Tc-HYNIC-annexin A5 has characteristics of high uptake and long retention in non-target tissues such as kidney and liver. To minimize this problem, we developed a novel (99m)Tc-labeled annexin A5 using a bis(hydroxamamide) derivative [C3(BHam)2] as a bifunctional chelating agent, and evalu...

H umanoid robotics is an emerging and challenging research field that has received significant attention during the past years and will continue to play a central role in robotics research and many applications of the 21st century. Regardless of the application area, one of the common problems dealt with in humanoid robotics is the understanding of humanlike information processing and the under...
