Evolutionary aspects in evaluating mutations in the melanocortin 4 receptor [PDF]
, 2007 More than 70 missense mutations have been identified in the human melanocortin 4 receptor (MC4R), and many of them have been associated with obesity. In a number of cases, the causal link between mutations in MC4R and obesity is controversially discussed.

The magnetospheric activity of bare strange quark stars
, 2011 In Ruderman & Sutherland (RS75) model, the normal neutron stars as pulsars bear a severe problem, namely the binding energy problem that both ions (e.g., ${}_{26}^{56}$Fe) and electrons on normal neutron star surface can be pulled out freely by the ...

Changes in the milk metabolome of the Giant Panda (Ailuropoda melanoleuca) with time after birth: three phases in early lactation and progressive individual differences [PDF]
, 2015 Ursids (bears) in general, and giant pandas in particular, are highly altricial at birth. The components of bear milks and their changes with time may be uniquely adapted to nourish relatively immature neonates, protect them from pathogens, and support ...

Dissipative Particle Dynamics for Systems with Polar Species
, 2019 In this work we developed a method for simulating polar species in the dissipative particle dynamics (DPD) method. The main idea behind the method is to treat each bead as a dumb-bell, i.e.

The Power of God and Miracles [PDF]
, 2015 In this paper we explicate the notion of a miracle and highlight a suitable ontological framework for it. Our proposal draws on insights from Aquinas’s discussion of miracles and from the modern ontology of powers.

The numbers of ringed seals (Phoca hispida) in Baffin Bay and associated waters
NAMMCO Scientific Publications, 1998 The size of the population of ringed seals (Phoca hispida) inhabiting Baffin Bay and associated waters was estimated by two methods. An approximate model of the energetics of the polar bear (Ursus maritimus) estimated an energetic need of about 16,000 MJ/

The Role of Satellite Telemetry Data in 21st Century Conservation of Polar Bears (Ursus maritimus)
Frontiers in Marine Science, 2022 Satellite telemetry (ST) has played a critical role in the management and conservation of polar bears (Ursus maritimus) over the last 50 years. ST data provide biological information relevant to subpopulation delineation, movements, habitat use, maternal
