The selection process for determining who represents the
American people in their statewide legislatures and executive mansions is
relatively standardized. Though ballots can differ between states, save for a
few areas that embrace ranked choice voting, the person with a plurality of
In this paper, we extend the design method previously
developed in the three-body problem to motion about asteroids. The authors
present a systematic method of generating optimal transfer orbits about
asteroids. Our systematic approach avoids the difficulties in selecting an
Sperm of D. melanogaster are among the longest known and
are evolving in concert with the female's long, coiled sperm storage organ,
the seminal receptacle (SR). During sperm competition, long sperm outcompete
short sperm but primarily in long SRs, providing a post-copulatory analog to
The Nef protein is responsible for T-cell activation and formation of a
persistent state of infection in HIV disease. Findings from the Sydney Blood
Bank Cohort and other case studies indicate that individuals infected with a
variant of HIV containing a defective nef gene displayed a slower...
Developmental arrest is an important and common feature
of nematode development. Many parasitic and non-parasitic nematodes have
arrested third stage larvae (L3), or dauers, that may be either obligate or
facultative stages in the life cycle. In addition, the non-parasitic...
The authenticity of newly discovered artifacts is critically important.
Scholars examine inscriptions
for linguistic consistency, carbon dates, and intentions, among other
factors. However, it can
often be difficult to determine authenticity. This raises problems within the
This paper examines differences in risk-taking and
competitiveness among biotechnology and pharmaceutical firms. It has been
argued that biotechnology firms, in contrast to pharmaceutical firms, face
higher levels of competitiveness and must pursue higher levels of risk-taking
as a result....
In recent years, advances in the field of collaborative robotics have enabled
people and robots to work in a shared environment. However, the complexity of
modeling human-robot interaction and difficulty of automating many tasks has
restricted the application range of collaborative robots....
Steel tub (box) girders are widely used for highway bridges. The slender
plate components of these structures are subject to local buckling. This
compressive limit state is particularly consequential in webs, midspan top
flanges, and continuous-over-support bottom flanges during...
According to the American College Health Association (2014), anxiety
disorders affect 21.8% of college students, surpassing depressive disorders
as the most widespread mental health concern in this population. Exposure to
stressful life events (SLE) can greatly exacerbate the chances for...
