Space and time are concepts that seem to be embedded in our very consciousness. As we grow up, our ‘intuitive understanding’
of these concepts seems to grow as well. And yet the fact is that our understanding of space-time in the deepest scientific
sense is far from complete, although we have covered a considerable distance along the route. There may still be many surprises
awaiting us on the road ahead. 相似文献

Explicitly Parallel Instruction Computing (EPIC) is an instruction processing paradigm that has been in the spotlight due to its adoption by the next generation of Intel Processors starting with the IA-64. The EPIC processing paradigm is an evolution of the Very Long Instruction Word (VLIW) paradigm. This article gives an overview of VLIW processor architecture. 相似文献

Non-alcoholic fatty liver disease and its more aggressive form, non-alcoholic steatohepatitis are entities that are becoming
more and more interesting to the medical community in general. A total of 93 Non-alcoholic fatty liver disease patients (64
male and 29 female) within the age range between 28 to 63 years were studied. All of them showed elevated alanine aminotransferase
level (104.07 ± 56.04). Aspartate aminotransferase level (58.13 ± 31.96) was elevated more than its normal level in 82% cases
and AST to ALT ratio was found 0.59 ± 0.26. Predisposing factors were diabetes mellitus (37%), obesity (13%) and hyperlipidemia
(41%). In addition, 32% of the subjects were overweight.18% of the patients had elevated serum bilirubin. Our findings recommend
a lower cutoff value than suggested by the World Health Organization for overweight and obesity among this racial-ethnic group. 相似文献

As developed and developing countries move towards greater technological development in the 21st century, the need for engineers has increased substantially. Japan is facing the dilemma of insufficient engineers; therefore, the country has to rely on foreign workers. This problem may be resolved if there is a continuous effort to increase the number of women engineers, who currently represent only 1%–2% of engineers in Japan. In this study, the satisfaction level of the learning experience of Japanese female engineering students was measured to determine its relationship with the students’ intention to choose engineering as their profession. Socio-cultural influences on the respondents’ intentions to pursue careers in the field were also studied. The findings revealed that learning experience was directly related to female students’ intention to pursue their career in engineering whereas socio-cultural values of a society have strong influences on students’ motivation to pursue careers in engineering in general. Additionally, some strategies are proposed to attract young girls to pursue engineering courses, as well as for current female engineering students to continue their studies and choose professions in the field as their career. 相似文献

In Part 1 of this two-part article we have spelt out, in some detail, the link between symmetries and conservation principles
in the Lagrangian and Hamiltonian formulations of classical mechanics (CM). In this second part, we turn our attention to
the corresponding question in quantum mechanics (QM). The generalization we embark upon will proceed in two directions: from
the classical formulation to the quantum mechanical one, and from a single (infinitesimal) symmetry to a multi-dimensional
Lie group of symmetries. Of course, we always have some definite physical system in mind. We also assume that the reader is
familiar with the elements of quantum mechanics at the level of a standard first course on the subject. Operators will be
denoted with an overhead caret, e.g., $
\hat A,\hat G,\hat U
$
\hat A,\hat G,\hat U
, etc., while $
[\hat A,\hat B] = \hat A\hat B - \hat B\hat A
$
[\hat A,\hat B] = \hat A\hat B - \hat B\hat A
is the commutator of $
\hat A
$
\hat A
and $
\hat B
$
\hat B
