Exploring the spin structure of the nucleon at STAR [PDF]

EPJ Web of Conferences
Understanding the internal spin structure of the nucleon remains a challenge in strong interaction physics. The unique capability of RHIC opened new avenues in studying the internal structure of the proton with unprecedented depth and precision ...

Strange quark stars: observations and speculations [PDF]

Journal of Physics G: Nuclear and Particle Physics, 2009
Two kinds of difficulties have challenged the physics community for many years: (1) knowing nature's building blocks (particle physics) and (2) understanding interacting many-body systems (many-body physics). Both of them exist in the research of quark matter and compact stars.

A new method for non‐invasive determination of effective pulmonary blood flow and cardiac output in spontaneously breathing subjects

Experimental Physiology, EarlyView.
Abstract The differential Fick method is well established for measuring effective pulmonary blood flow (EPBF) and cardiac output (CO) but until now it has only been used for patients on mechanical ventilation. Here we present and evaluate a new approach adapted to spontaneous breathing situations.

Proto-strange quark stars from density-dependent quark mass model

European Physical Journal C: Particles and Fields
In this paper, we investigate the evolution of strange quark stars (SQS) from birth as proto-strange quark stars to maturity as stable SQSs at a zero temperature.

PSR B1257+12: a quark star with planets?

, 2007
A recent observation has shown that PSR B1257+12 could have quite small X-ray emitting area, only about 2000 m$^2$, which is more than three orders smaller than the canonical polar cap size.

Sex and performance‐level differences in aerobic and haematological parameters among elite ski mountaineering athletes

Experimental Physiology, EarlyView.
Abstract Ski mountaineering (SkiMo) is a new Olympic sport with extreme endurance demands and altitude exposure. Previous studies have focused on traditional cardiorespiratory variables, such as maximal oxygen consumption (V̇O2max${\dot V_{{{\mathrm{O}}_{\mathrm{2}}}{\mathrm{max}}}}$) or ventilatory thresholds, but, to our knowledge, did not report ...

Extended quark mean-field model for neutron stars

, 2014
We extend the quark mean-field (QMF) model to strangeness freedom to study the properties of hyperons ($\Lambda,\Sigma,\Xi$) in infinite baryon matter and neutron star properties.

A new method for bedside determination of effective lung volume and functional residual capacity

Experimental Physiology, EarlyView.
Abstract Established methods of measuring functional residual capacity (FRC) involve sophisticated equipment and elaborate procedures. Here we present a new method based on CO2 rebreathing that has a simple fast procedure and only requires end‐tidal CO2 monitoring. Ten healthy subjects with diverse anthropometric and respiratory parameters were studied

SGR 0418+5729 as an evolved Quark-Nova compact remnant

, 2011
Soft gamma repeaters and anomalous X-ray pulsars are believed to be magnetars, i.e. neutron stars powered by extreme magnetic fields, B~10^(14)-10^(15) Gauss.
