Temperature Dependent Motion of a Massive Quantum Particle  [PDF]
Jian-Ping Peng
Journal of Modern Physics (JMP) , 2012, DOI: 10.4236/jmp.2012.37083
Abstract: We report model calculations of the time-dependent internal energy and entropy for a single quasi-free massive quantum particle at a constant temperature. We show that the whole process started from a fully coherent quantum state to thermodynamic equilibrium can be understood, based on statistics of diffracted matter waves. As a result of thermal interaction between the particle and its surroundings, the motion of the particle shows new feature.
Entropy of a Free Quantum Particle  [PDF]

Journal of Modern Physics (JMP) , 2012, DOI: 10.4236/jmp.2012.312241
Abstract: The time-dependent entropy of a single free quantum particle in the non-relativistic regime is studied in detail for the process started from a fully coherent quantum state to thermodynamic equilibrium with its surroundings at a finite temperature. It is shown that the entropy at the end of the process converges to a universal constant, as a result of thermal interaction.
Antioxidant Activity of Polyphenolic Compounds from Dalbergia odorifera T. Chen

Pakistan Journal of Nutrition , 2011,
Abstract: Seven compounds were isolated from Dalbergia odorifera T. Chen and their antioxidant activities were studied with Oil Stability Index (OSI) method, reducing power and radical scavenging methods. The compounds were identified by spectroscopic methods as (1) pinocembrin (2) biochanin A (3) sativanone (4) biochanin B (5) naringenin (6) 3'-hydroxymelanettin and (7) eriodictoyl. Results showed that compounds 6 and 7 exhibited stronger antioxidant activity than commonly used synthetic antioxidant BHT in the presented study.

Acta Crystallographica Section E , 2008, DOI: 10.1107/s1600536807062666
Abstract: In the crystal structure of the title compound, C8H5N3O3, intermolecular N—H...O hydrogen bonds link molecules into centrosymmetric dimers. These dimers are, in turn, linked though weak intermolecular C—H...O and C—H...N hydrogen bonds and π–π stacking interactions, with centroid–centroid distances of 3.678 (3) , into a three-dimensional network.

Acta Crystallographica Section E , 2008, DOI: 10.1107/s1600536808006788
Abstract: In the title centrosymmetric compound, [Hg2Cl4(C26H22N6O)2], each HgII center adopts a distorted HgN3Cl2 trigonal bipyramidal coordination geometry, formed by two pyridine N atoms, one imine N atom and two chloride anions. Within the organic ligand, the oxadiazole ring is nearly coplanar with the two benzene rings [dihedral angles = 5.9 (4) and 6.5 (4)°] and nearly perpendicular to the two pyridine rings with the same dihedral angle of 77.4 (4)°. The two organic ligands bridge two HgII ions to form the macrocyclic complex. Intermolecular N—H...Cl and N—H...N hydrogen bonding helps to stabilize the crystal structure.

Multiple nonnegative solutions for BVPs of fourth-order difference equations
Sun Jian-Ping
Advances in Difference Equations , 2006,
Abstract: First, existence criteria for at least three nonnegative solutions to the following boundary value problem of fourth-order difference equation Δ4x(t-2) = a(t)f(x(t)),t ∈ [2, T], x(0) = x(T + 2) = 0, Δ2x(0) = Δ2x(T) = 0 are established by using the well-known Leggett-Williams fixed point theorem, and then, for arbitrary positive integer m, existence results for at least 2m-1 nonnegative solutions are obtained.

Methodological quality assessment of clinical trials in traditional Chinese medicine: the principles of evidence-based medicine
Jian-Ping LIU
Zhong Xi Yi Jie He Xue Bao , 2006,
Abstract: The quality of clinical trials in traditional Chinese medicine (TCM) was analyzed with respect to their methodology and outcome assessment according to the concepts of evidence-based medicine (EBM). It was suggested that the essential methodological principles of EBM should be applied in clinical trials of TCM, including randomization, control and blindness. The sample size estimation, optimal parameter selection for outcome assessment, compliance and intention-to-treat analysis are all important aspects of randomized controlled trials. To bring the benefits of EBM into clinical trials will improve the quality of research in TCM and also promote international co-operation and communications. It is necessary to establish an assessment system of clinical outcome for TCM on the basis of EBM in order to evaluate the efficacy and safety of TCM objectively and scientifically.
Evidence-based medicine and individualized health care
Jian-ping LIU
Zhong Xi Yi Jie He Xue Bao , 2009,
Abstract: In 21st century, clinical medicine moves toward a model of individualized health care. The development of the individualized model is based on the research findings of human genomics project including genotype and single nucleotide polymorphisms (SNPs), as well as the new health care model, that is, biological-psychological-social-environmental-spiritual. It reflects the idea of patient-centered care, and corresponds to the traditional practice of Chinese medicine, which addressed the individualized therapy on the basis of symptom pattern differentiation. However, the era of evidence-based medicine affords new meanings of individualized health care and promotes the research on the practice. The practice based on evidence would happen upon the integration of external research evidence, the expertise and experience of practitioners, and the value and preference of patients, so the decision of health care will be conscientious, explicit and judicious. This assay describes the meanings of individualized health care in different medical contexts, the characteristics of individualized practice in Chinese medicine, and proposals for further research in practice.
