RNaseH-mediated simultaneous piggyback knockdown of multiple genes in adult zebrafish
This article tests if it is possible to piggyback more than one antisense deoxyoligonucleotide (dO) with one vivo morpholino (VMO). The authors previously developed a piggyback knockdown method that was used to knockdown genes in adult zebrafish. In this article, the authors develop a method to knockdown three genes at one time, and by increasing the concentration of VMO by twofold, could knockdown six genes simultaneously. These multiple gene knockdowns will not only increase the efficiency of the method in whole genome-wide knockdowns but will also be useful to study multifactorial disorders.

A New Cable-Less Seismograph with Functions of Real-Time Data Transmitting and High-Precision Differential Self-Positioning
This article developed a new cable-less seismograph system, which can transmit seismic data in real-time and automatically perform high-precision differential self-positioning. Combining the ZigBee technology with the high-precision differential positioning module, this new seismograph system utilized the wireless personal area network (WPAN) and real-time kinematic (RTK) technologies to improve its on-site performances and to make the field quality control (QC) and self-positioning possible. With the advantages of low-cost, good scalability, and good compatibility, the proposed new cable-less seismograph system can improve the field working efficiency and data processing capability. It has potential applications in noise seismology and mobile seismic monitoring.

A Bayesian Rate Ratio Effect Size to Quantify Intervention Effects for Count Data in Single Case Experimental Research
This article formulates a within-subject Bayesian rate ratio effect size (BRR) for autocorrelated count data that would obviate the need for small sample corrections. The authors illustrate this within-subject effect size using real data for an ABAB design and provide codes for practitioners who may want to compute BRR.

A Signature Assignment Puts Vegetables on the Line
This is an unpublished manuscript that delves into the use of Signature Assignments (SAs) which are real-world applications that embed curriculum learning objectives in routine classwork and facilitate assessment of outcomes across classes and disciplines. SAs tied to key learning objectives demonstrate student growth and reveal areas where instructional improvement might be needed. Additionally, SAs tied to curriculum objectives contribute to program and university understanding of teaching strategies that promote student success.

A Novel Prodrug Approach for Central Nervous System-Selective Estrogen Therapy
This article gives an overview of the discovery of small-molecule bioprecursor prodrugs carrying the para-quinol scaffold on the steroidal A-ring that are preferentially metabolized in the CNS to the corresponding estrogens. Selected examples are shown to illustrate that, independently of the route of administrations and duration of treatments, these agents produce high concentration of estrogens only in the CNS without peripheral hormonal liability. 10β,17β-Dihydroxyestra-1,4-dien-3-one (DHED) has been the best-studied representative of this novel type of prodrugs for brain and retina health. Specific applications in preclinical animal models of centrally-regulated and estrogen-responsive human diseases, including neurodegeneration, menopausal symptoms, cognitive decline and depression, are discussed to demonstrate the translational potential of their prodrug approach for CNS-selective and gender-independent estrogen therapy with inherent therapeutic safety.

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.

Persistent spin helix in Rashba-Dresselhaus ferroelectric CsBiNb2O7
Article reporting that CsBiNb₂O₇, a layered perovskite of Dion-Jacobson type, is a robust ferroelectric with sufficiently strong spin-orbit coupling and spin texture reversible by electric field. The study reveals that its topmost valence band's spin texture is quasi-independent from the momentum, as a result of the low symmetry of its ferroelectric phase. The peculiar spin-polarization pattern in the momentum space may yield the so-called “persistent spin helix,” a specific spin-wave mode which protects the spin from decoherence in the diffusive transport regime, potentially ensuring a very long spin lifetime in this material.
