Evaluation of Metadata Change in Authority Data Over Time: An Effect of a Standard Evolution
This article presents some results of the content analysis study that explores the authority data change over time in response to change in standards. Authority data describes persons, institutions, places, events, and works, as well as relations between them. This study contributes to the understanding of metadata change and its relation to functionality of authority records and improved information access.

Hypoxic level and duration differentially affect embryonic organ system development of the chicken (Gallus gallus)
This article investigates how key organ systems are affected by hypoxia. The results indicated that either modest hypoxia (15% O2) throughout development, or hypoxia at any level during the late stages (d 11 to 18), increased the heart and chorioallantoic membrane weight, which partly compensated for the detrimental effects of hypoxia on embryonic development.

A gene based approach to test genetic association based on an optimally weighted combination of multiple traits
In this article, the authors propose a statistical method by Testing an Optimally Weighted Combination of Multiple traits (TOW-CM) to test the association between multiple traits and multiple variants in a genomic region (a gene or pathway). They investigate the performance of the proposed method through extensive simulation studies. Their simulation studies show that the proposed method has correct type I error rates and is either the most powerful test or comparable with the most powerful tests. Additionally, they illustrate the usefulness of TOW-CM based on a COPDGene study.

Emerging Trend in the Pharmacotherapy of Osteoarthritis
Article covers the emerging trends of pharmacologic therapies for osteoarthritis (OA) such as traditional OA drugs (acetaminophen, non-steroidal anti-inflammatory drugs (NSAIDs), opioids, serotonin-norepinephrine reuptake inhibitors (SNRIs), intra-articular injections of corticosteroids, and dietary supplements), which are effective in pain relief but not in reversing damage, and are frequently associated with adverse events.

A Tough, Water-Resistant, High Bond Strength Adhesive Derived from Soybean Meal and Flexible Hyper-Branched Aminated Starch
This article highlights the development of a flexible long-chain starch with a hyper-branched structure (HD), and incorporating it with SM and a crosslinking agent to prepare a novel SM adhesive. Results showed that this adhesive exhibited both excellent water resistance and enhanced toughness. The wet bond strength of plywood fabricated using this adhesive was 354.5% higher than that of SM adhesive.

Tribologically induced nanolaminate in a cold-sprayed WC-reinforced Cu matrix composite: a key to high wear resistance
Article describes an experiment where a self-organized 2D nanolaminate with an average lamella thickness of ~22 nm was formed in the subsurface of a cold-sprayed WC-reinforced metal matrix composite (MMC) Cu-MoS2-WC during oscillatory sliding, resulting in more stable friction and improved wear resistance.

Computational Study of 3d Metals and Their Influence on the Acidity of Methane C–H Bonds
Article describes experiment where CCSD(T) methods in conjunction with correlation consistent basis sets were used to predict the pKa for the deprotonation of methane in a 3d metal ion adduct, [M···CH4]+ (M = Sc–Cu), in dimethyl sulfoxide solvent, which is modeled by the SMD continuum solvent model.

Evaluation of Uniformity of Bamboo Bundle Veneer and Bamboo Bundle Laminated Veneer Lumber (BLVL)
In this article the density uniformity and mechanical properties of bamboo bundle veneers were systematically evaluated by the combination of light transmittance and mechanical stiffness. It was found that the number of broomings, dippings, and high-temperature heat treatments had different effects on the bamboo bundle veneers. On this basis, the uniformity of the density and mechanical properties of the bamboo scrimber (BS) that underwent hybrid paving, and the bamboo bundle laminated veneer lumber (BLVL), were analyzed.
