Evaluating juvenile post-stocking survival and adult paddlefish spatial distribution for recreational fishery potential in a large reservoir

Angler interest in targeting Paddlefish Polyodon spathula is growing throughout the Missouri and Mississippi River basins. In response, state agencies are increasing management efforts (e.g., stocking) and evaluating whether restored or maintained populations are suitable candida...

Performance Assessment of Type IL Cement in Concrete: Influence of Cement Source and Admixture Compatibility

Abstract This study evaluated the performance of concrete and mortar made with three portland limestone (Type IL) cement sources, collected from Texas, Colorado, and Florida, in combination with two types of chemical admixtures including water reducing and air entraining admixtur...

Influence of an oregano-based essential oil on growth performance and carcass traits of beef steers

Abstract The objective of this study was to determine the influence of an oregano-based essential oil on growth performance, health outcomes, and carcass characteristics of yearling beef steers finished in an all-natural program. Single-sourced yearling steers [N = 128; initial b...

Metagenome shotgun sequencing allows insights into the functional potential of the vaginal microbiome associated with pelvic organ prolapse in sows

Abstract Pelvic organ prolapse (POP) is a leading cause for sow mortality in the United States. Recent work has evaluated biological factors associated with POP, and differences have been observed within the vaginal microbiota of sows at high risk using 16S rRNA gene amplicon seq...

193. Increasing Organic Trace Mineral Supplementation During Late Gestation and Lactation Influences Sow Iron Status and Litter Weaning Performance in Prolific Sows.

Abstract The objective of this study was to evaluate the effects of increasing dietary TM supplementation during late gestation and lactation on reproductive performance and sow and progeny iron status. Forty-five sows (parity 0–4) at 70 ± 2 d of gestation were alloted by parity,...

Integrating Insight and Uncertainty: Bayesian modeling for data-rich livestock systems

Abstract Bayesian statistical modeling provides a principled framework for integrating biological knowledge, process understanding, and observed data in animal science research. By treating all unobserved quantities as random variables and explicitly defining probability distribu...

Trends in south pole particle concentrations imply holocene westerly wind strengthening

The Southern Hemisphere Westerly Winds (SHWW) play an important role in global climate and Antarctic ice sheet dynamics; however, high-resolution proxy reconstructions are sparse. Conflicting evidence suggests SHWW latitudinal change, weakening and/or strengthening, throughout th...

Ultrahigh Performance Concrete Beams with Transverse Openings: Evaluating Effects and Reinforcement Strategies

Abstract This paper evaluates the behavior of ultrahigh performance concrete (UHPC) beams with transverse openings, a topic with practical implications that has not been studied thus far. Various parameters were examined; including the opening shape, location, and height; compres...

A Phase II Trial Using Grape Seed Extract for Prostate Cancer Patients With Nonmetastatic Prostate‐Specific Antigen Progression After Local Therapy

ABSTRACT Prostate cancer (PCa) is a major cause of cancer‐related death among American men. While androgen deprivation therapy (ADT) is commonly used in the treatment of rising prostate‐specific antigen (PSA) levels after primary therapy, its adverse systemic side effects support...

Review of AI-driven discovery of cathode anode and electrolyte materials for advancing sodium-ion batteries

Abstract Sodium-ion batteries (SIBs) are emerging as a sustainable, cost-effective alternative to lithium-ion batteries (LIBs) for grid storage, electric vehicles, and electronics. However, commercialization depends on overcoming the performance bottlenecks in energy density, kin...

Predicting Competitive Bidding Levels in Transportation Projects Using Explainable Machine Learning and Deep Learning Methods

Abstract Maintaining robust competition in transportation construction bidding is challenging for State Departments of Transportation (DOTs) as they navigate fluctuating input prices, complex project scopes, and variable market conditions. Existing approaches to forecasting bidde...

Deindividuation Among Gendered Violence Survivors and Posting About #MeToo

Abstract: Individuals have numerous channels to choose from when posting online, particularly when posting about sensitive or highly personal topics. This study uses the social identity model of deindividuation effects to examine why individuals posted about the #MeToo movement,...

Effectiveness of the Pasture, Rangeland, and Forage Rainfall Index ( PRF ‐ RI ) Program: Interval Selections With Uniform Premium Subsidy Rates

ABSTRACT This study examines interval selection in the Pasture, Rangeland, and Forage Rainfall Index (PRF‐RI) program and evaluates how uniform premium subsidy rates affect optimal interval selections. Using South Dakota as a case study, we show a trend of increasing selection of...

Influence of Limit-Feeding Duration on Growth Performance and Carcass Traits of Finishing Steers

Abstract Beef cattle are commonly limit-fed during the backgrounding period to improve feed efficiency and control fat deposition, but the effects of limit feeding duration in the finishing period remains unclear. The objective of this study was to determine the effect of limit f...

Genome-wide association mapping of major QTLs for resistance to bacterial leaf-streak disease (Xanthomonas translucens pv. undulosa) in elite hard winter wheat germplasm

Bacterial leaf streak (BLS), caused by Xanthomonas translucens pv. undulosa ( Xtu ), is an increasing threat to wheat ( Triticum aestivum L .) production in the Northern Great Plains of the United States, where severe epidemics can cause up to 60% yield losses in susceptible geno...

Molecular and Physiological Mechanisms of Steroidal Implants in Beef Cattle: A Review from the U.S. Production Perspective

For decades, beef cattle producers have safely used steroidal implants as a low-cost, highly effective growth technology, delivering improvements in average daily gain (10 to 30%) and feed efficiency (5 to 15%) compared with non-implanted cattle. These improvements stem from incr...

Evolution of Bed Shear Stress in Open-Channel Flow at Smooth-to-Rough and Rough-to-Smooth Transitions

Abstract The evolution of bed shear stress in open-channel flows due to a sudden change in bed roughness was investigated for rough-to-smooth (RTS) and smooth-to-rough (STR) transitions. The velocity field was measured in the longitudinal–vertical plane at high spatial resolution...

Tramadol Co‐Administration with Oxycodone or Hydrocodone Increases Opioid Burden without Improving Postoperative Pain Control

Tramadol is frequently co-prescribed with oxycodone or hydrocodone after surgery under the assumption that its dual mechanism of action provides an opioid-sparing benefit. However, evidence supporting this practice is limited and inconsistent. We conducted a secondary analysis of...

Methane Emissions From Wildfires: Trends and Anomalies

Abstract Wildfires emit smoke particles and trace gases including greenhouse gases into the atmosphere, impacting the environment and leading to detrimental impacts on human health and economy. The estimation of spatially and temporally resolved methane emissions from biomass bur...
