Nature's Complexity Alive: Farewell to Several Unificatory Cosmological Arguments for Monism

Noûs, EarlyView.
ABSTRACT Throughout history, numerous thinkers have claimed that monism—in the form of priority monism, existence monism, monotheistic monism, or versions that posit an extra‐cosmic ultimate being—theoretically surpasses pluralism, above all by positing a unified universe.

Study of the Ground-State Energies of Some Nuclei Using Hybrid Model

Advances in High Energy Physics, 2021
The quark-quark (QQ) interaction as a perturbed term to the nucleon-nucleon interaction (NN) without any coupling between them is studied in a hybrid model. This model is used to calculate the ground-state energies of 2H1 and 4He2 nuclei.

On the Naturalistic Grounds of Grounding

Ratio, EarlyView.
ABSTRACT This paper examines whether grounding can be naturalized. We adopt a tripartite framework—Ocat (scientific catalogue of existents), Otyp (ontological types), and metaphysics (natures/modal profiles)—and show that classifying as such the relata of putative grounding claims forces a dilemma.

Cerebral oxygen extraction across different exercise intensities: Role of arterial PCO2${P_{{\mathrm{C}}{{\mathrm{O}}_2}}}$

Experimental Physiology, EarlyView.
Abstract Stability in cerebral oxygen extraction fraction (OEF) is typically determined by alterations in cerebral blood flow (CBF). At rest, arterial partial pressure of carbon dioxide (PaCO2${P_{{\mathrm{aC}}{{\mathrm{O}}_2}}}$) and OEF exhibit a strong inverse relationship owing to the powerful influence of PaCO2${P_{{\mathrm{aC}}{{\mathrm{O}}_2}}}$

The constituent quark model

In this chapter we give a pedagogical introduction to the constituent quark model. The explanation of magnetic moments of the nucleons was crucial to introduce an effective quark mass for light quarks that nowadays are understood as an effect of Spontaneous Chiral Symmetry Breaking in QCD.

Eight weeks of post‐exercise local heating does not improve cognition and plasma brain‐derived neurotrophic factor concentrations

Experimental Physiology, EarlyView.
Abstract Exercise and heat stress have been reported to independently provide benefits to brain health. We tested the hypothesis that 8 weeks of post‐exercise local heating, passive local heating only, or exercise training only improves cognitive performance compared to a control group.

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.
