Relic Neutrino Helicity Evolution in Galactic Magnetic Field and Its Implications
We simulate the evolution of the helicity of relic neutrinos as they
propagate to Earth through a realistic model of the Galactic magnetic field,
improving upon the rough estimates in the pioneering work of Baym and Peng. We
find that with magnetic moments consistent with experimental bounds and even
several orders of magnitude smaller, the helicity of relic neutrinos rotates
with a substantial directional anisotropy. Averaged over directions this would
simply reduce the apparent flux; if the direction of the incident neutrino
could be measured, the directional anisotropy in the interaction probability
could become a powerful diagnostic. We study the effects of spin rotation
on CB detection through the inverse tritium decay process.Comment: 8 pages,7 figure
The study of relationships between the collaboration for supply chain, supply chain capabilities and firm performance: A case of the Taiwan׳s TFT-LCD industry
[[abstract]]Academic and business fields have frequently examined the significance and influence of collaborative development interactions and feedback mechanisms for supply chain value innovation. Value co-creation and value constellations, which serve as innovation drivers in channel integration, are positively associated with supply chain performance. We investigated the relationships among collaborative supply chain value innovation (CSCVI), supply chain capabilities (SCCs), and firm performance by examining a case of the thin-film transistor liquid crystal display (TFT-LCD) industry in Taiwan.[[notice]]補正完畢[[incitationindex]]SSCI[[booktype]]紙

Noninvasive prediction of Blood Lactate through a machine learning-based approach.
We hypothesized that blood lactate concentration([Lac]blood) is a function of cardiopulmonary variables, exercise intensity and some anthropometric elements during aerobic exercise. This investigation aimed to establish a mathematical model to estimate [Lac]blood noninvasively during constant work rate (CWR) exercise of various intensities. 31 healthy participants were recruited and each underwent 4 cardiopulmonary exercise tests: one incremental and three CWR tests (low: 35% of peak work rate for 15 min, moderate: 60% 10 min and high: 90% 4 min). At the end of each CWR test, venous blood was sampled to determine [Lac]blood. 31 trios of CWR tests were employed to construct the mathematical model, which utilized exponential regression combined with Taylor expansion. Good fitting was achieved when the conditions of low and moderate intensity were put in one model; high-intensity in another. Standard deviation of fitting error in the former condition is 0.52; in the latter is 1.82 mmol/liter. Weighting analysis demonstrated that, besides heart rate, respiratory variables are required in the estimation of [Lac]blood in the model of low/moderate intensity. In conclusion, by measuring noninvasive cardio-respiratory parameters, [Lac]blood during CWR exercise can be determined with good accuracy. This should have application in endurance training and future exercise industry
Oxygen-covered tungsten crystal shape: time effects, equilibrium, surface energy and the edge-rounding temperature
The equilibrium crystal shape (ECS) of oxygen-covered tungsten micricrystal
is studied as a function of temperature. The specially designed ultrafast
crystal quenching setup with the cooling rate of 6000 K/s allows to draw
conclusions about ECS at high temperatures. The edge-rounding transition is
shown to occur between 1300 K and 1430 K. The ratio of surface free energies
is determined as a function of temperature.Comment: 8 pages, 10 figures, submitted for publicatio
