Excitation spectrum of the Holstein model [PDF]

Physical Review B, 1998
In this paper the polaron problem for the Holstein model is studied in the weak coupling limit. We use second order perturbation theory to construct renormalized electron and phonons. Eigenstates of the Hamiltonian are labelled and the excitation spectrum is constructed.

Hyperpolarization of [1‐13C]Ketoisocaproate‐d2 by Reversible Exchange with Parahydrogen Enables Profiling of Branched‐Chain‐Amino‐Acid Metabolism in Cellulo and in Vivo

Advanced Science, EarlyView.
We report the fast generation of biocompatible solutions of highly 13C‐hyperpolarized (≈11%) partially‐deuterated ketoisocaproate within <6 min using spin‐lock‐induced crossing and reversible exchange with parahydrogen (SLIC‐SABRE). This enables rapid detection of branched‐chain‐amino‐acid transferase 1 (BCAT1) protein expression and investigation of ...

The effect of probiotic nutrition of Saccharomyces boulardii and Saccharomyces cerevisiae on yield, antioxidant activity and expression of interleukin-6 gene in Holstein calves

Journal of the Indonesian Tropical Animal Agriculture, 2020
An experiment was performed to investigate the probiotic effect of Saccharomyces boulardii and Saccharomyces cerevisiae on yield, antioxidant activity, and expression of interleukin-6 gene in Holstein calves.

Integrated Small RNA Sequencing, Transcriptome and GWAS Data Reveal microRNA Regulation in Response to Milk Protein Traits in Chinese Holstein Cattle

Frontiers in Genetics, 2021
Milk protein is one of the most important economic traits in the dairy industry. Yet, the regulatory network of miRNAs for the synthesis of milk protein in mammary is poorly understood.

Bio-Economic Comparison of Pure Holstein, Simmental × Holstein, and Montbéliarde × Holstein Crossbred Dairy Cows

Animals
The economic performance of Holstein, Montbéliarde × Holstein, and Simmental × Holstein cows was evaluated using a bio-economic model. The results showed differences in income and costs between crossbred and pure Holstein groups. The Montbéliarde–Holstein crossbreds had the highest milk income ($2223) and profitability ($1002) compared to the Simmental

Plaid‐Like Spin Splitting and Chirality of Magnon Bands in Antiferromagnetic MnTe2

Advanced Science, EarlyView.
Helicity‐ and angle‐resolved Raman spectroscopy reveals chiral magnons in the non‐coplanar antiferromagnet MnTe 2. Combined with first‐principles calculations and spin‐wave theory, the results establish its altermagnetic character through circular Raman dichroism, reduced rotational symmetry, and a distinctive plaid‐like momentum‐space magnon spin ...

A comparative study on milk composition of Jersey and Holstein dairy cows during the early lactation

Journal of Animal Science and Technology, 2020
Recently, Jersey cattle was introduced and produced by embryo transfer to Korea. This study was conducted to investigate the differences of milk compositions between Jersey and Holstein cows and the relationship ...

Intrinsic Phonons as a Dynamic Control Knob for Catalytic Reactivity in 2D Materials

Advanced Science, EarlyView.
Intrinsic phonon excitations are demonstrated to serve as a dynamic control knob for catalytic reactivity in 2D materials. Mode‐selective lattice vibrations reconstruct the electronic structure, lower oxygen evolution reaction barriers, establishing a phonon‐engineering paradigm for dynamically regulating electrocatalysis beyond conventional static ...

ELF5‐Mediated Enhancer–Promoter Interaction Regulates LALBA Expression in Ovine Mammary Gland

Advanced Science, EarlyView.
In the study, we systematically investigate the epigenetic mechanisms underlying lactation traits in sheep by integrating transcriptomic, chromatin accessibility, histone modification, and functional analyses. We identify a super‐enhancer at the LALBA locus and demonstrate that enhancer E4 functions as its core regulatory element.

Genome-wide associations for milk production and somatic cell score in Holstein-Friesian cattle in Ireland [PDF]

, 2012
peer-reviewedBackground: Contemporary dairy breeding goals have broadened to include, along with milk production traits, a number of non-production-related traits in an effort to improve the overall functionality of the dairy cow.
