We have studied tilted surface layers in the bulk SmA temperature window of one liquid crystal using null transmission ellipsometry. Five distinct nonplanar surface structures were observed. We present analyses of the tilt and azimuthal profiles of the structures and examine the transitions between the structures. The transitions are identified as a double reentrant synclinic-anticlinic-synclin...

Replacement of protons by deuterons in the glassing solvents led to 2-3-fold improvement of the (13)C dynamic nuclear polarization (DNP) solid-state NMR signal for samples doped with large electron spin resonance (ESR) linewidth free radicals galvinoxyl, DPPH, and 4-oxo-TEMPO. Meanwhile, the reverse effect is observed for (13)C DNP using small ESR linewidth free radicals BDPA and trityl OX063.

According to astrophysical and cosmological observations, about 20 percent of the total energy in the universe is contributed by dark matter, which, within present observational limits, only exhibits gravitational interaction. Meanwhile, the Standard Model of elementary particles don’t contain such weakly-interacting constituents. To solve this mystery several schemes extending the Standard Mod...

P atient positioning is an important aspect of anesthesia practice. Based on data from the American Society of Anesthesiologists Closed Claims Project database, advancements in research, improvements in airway management and education, and development of airway devices have resulted in a substantial decrease in respiratory complications—at one time the major cause of anesthesia-related morbidit...

Several synthetic pesticides and allelochemicals used to treat Triatoma infestans adults by topic application showed some degree of cytosolic glutathione S-transferase (GST) induction. General inducers of detoxication systems such as phenobarbital and 3-methylcholantrene topically applied on T. infestans resulted in no GST induction. Meanwhile, general insecticide synergist such as piperonyl bu...

The previous government had significant problems with healthcare IT. There were a number of serious scandals; some (like the problems with developing hospital systems) cost tens of millions of pounds of taxpayers’ money; others (such as the London Ambulance Service fiasco) cost lives. Meanwhile, doctors have lost confidence in the Department of Health’s Information Management and Technology (IM...

Malicious behaviors and cooperation have been well studied separately. However, rare systematic study has been conducted on the combination of them: malicious cooperation. In this paper, a general quantitative utility function of malicious cooperation is firstly formulated in a congestion game framework. Both objective and subjective factors are incorporated (e.g., malicious social networks and...

Conical shock waves are generated as sharp conical solid projectiles fly supersonically in the air. We study such conical shock waves in steady supersonic flow using isentropic Euler system. The stability of such attached conical shock waves for non-symmetrical conical projectile and non-uniform incoming supersonic flow are established. Meanwhile, the existence of the solution to the Euler syst...

The paper takes the web information of product quality safety as research object. Aiming at its transmission characteristic at social network, information transmission model based on government intervention is presented. Meanwhile, the influence of information transmission with government intervention is analyzed. Lastly we adopted BA network to build human relation model, used MATLAB tool to s...

This paper proposes an experiment about the attitude toward probabilities on a population of portfolio managers. Its aim is to check whether or not portfolio managers are neutral toward probabilities. Meanwhile, it presents a experimental protocole that highlights an inconsistency between two experimental techniques. It also introduces a new functional form for the probability weighting functio...
