Fractionnally charged excitations in the charge density wave state of a quarter-filled t-J chain with quantum phonons

open access: yes, 2001
Elementary excitations of the 4k$_F$ charge density wave state of a quarter-filled strongly correlated electronic one-dimensional chain are investigated in the presence of dispersionless quantum optical phonons using Density Matrix Renormalization Group ...

Multiple Roles of Protamine Kinase SRPK1 and Phosphatase PP1γ in Sperm Development

open access: yesPROTEOMICS, EarlyView.
ABSTRACT Protein phosphorylation regulates key events of male germ cell differentiation. In the testis, SRPK1 and PP1γ are involved in protamine phosphorylation and dephosphorylation, respectively, and their deregulation is linked to defective chromatin structure and male infertility.

African swine fever: A highly fatal disease that is spreading globally

open access: yesOpen Veterinary Journal
African swine fever (ASF) is caused by the ASF virus (ASFV), a double-stranded DNA virus classified under the family Asfarviridae and genus Asfivirus. Although outbreaks have been occurring since 1909, ASF was first documented in Kenya in 1921. The three

Quantum phases of a Feshbach-resonant atomic Bose gas in one dimension

open access: yes, 2005
We study an atomic Bose gas with an s-wave Feshbach resonance in a one-dimensional optical lattice, with the densities of atoms and molecules incommensurate with the lattice.

Association of arthritis and total joint arthroplasty with self‐reported function in former professional American‐style football players

open access: yesPM&R, EarlyView.
Abstract Background Participation in American‐style football (ASF) results in trauma‐related concerns including joint injuries. Limited work has described arthritis and knee and hip total joint arthroplasty (TJA) in this population. The association of these conditions to pain interference and physical and mental function has not been well described ...

Anomalous pairing of bosons: Effect of multi body interactions in optical lattice

open access: yes, 2017
An interesting first order type phase transition between Mott lobes has been reported in Phys. Rev. Lett. 109, 135302 (2012) for a two-dimensional Bose-Hubbard model in the presence of attractive three-body interaction.

Permafrost Distribution in the Canadian Rockies: Key Variables Influencing Patch‐Scale Variability

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT The spatial distribution of permafrost in mountainous regions is influenced by various factors such as topography, climate, vegetation, and substrate. Despite the existence of comprehensive permafrost maps at national and global levels, they fail to accurately represent the patch‐scale (e.g., < 25 m) permafrost distribution in characteristic ...

Environmental impact assessment of dietary scenarios: a comparison of methodological aspects [PDF]

open access: yes, 2018
Background Dietary patterns have manifold impacts on the environment. • However, studies that assess dietary patterns operate with varying methodological approaches and underlying assumptions, which evoke different, and occasionally even contradicting,

ASF+ eine ASF - ähnliche Spezifikationssprache

open access: yes, 1994
Ohne auf wesentliche Aspekte der in [Bergstra&al.89] vorgestellten alge-braischen Spezifikationssprache ASF zu verzichten, haben wir ASF um die folgenden Konzepteerweitert: Während in ASF einmal exportierte Namen bis zur Spitze der Modulhierarchie sichtbarbleiben müssen, ermöglicht ASF + ein differenziertes Verdecken von Signaturnamen.
