Interrelationships Between Pattern Of Fermentation During Ensilage And Initial Crop Composition, J M. Wilkinson, P F. Chapman, R J. Wilkins, R F. Wilson Jun 2026

Interrelationships Between Pattern Of Fermentation During Ensilage And Initial Crop Composition, J M. Wilkinson, P F. Chapman, R J. Wilkins, R F. Wilson

IGC Proceedings (1977-2023)

Relationships between crop composition and silage composition were examined for 231 silages made at the Grassland Research Institute from 1968 to 1978 without additives. A test was made of the model of Weissbach et al. (1974) in which silage characteristics were related to the percentage of dry matter in the crop (OM) and the ratio of sugar (Z) to buffering capacity (PK). Although these factors accounted for significant variance, the percentage accounted for was low at 36 % for lactic acid (percentage of total acids), 26 % for Flieg's score, 22 % for ammonia N (percentage of total N), and …

Effect Of Delayed Sealing During Ensiling On Fermentation And Dry-Matter Loss, N Takano, Y Masaoka, T Manda Jun 2026

Effect Of Delayed Sealing During Ensiling On Fermentation And Dry-Matter Loss, N Takano, Y Masaoka, T Manda

IGC Proceedings (1977-2023)

Two experiments were carried out from 1976 to 1980 to ascertain the effect of delayed sealing of silo on fermentation, dry· matter (DM) loss, digestibility, and silage intake. The effect of delayed sealing (up to 72 hours) of grass and corn silage was tested in laboratory silos on fermentation quality with storage temperatures at 15°C and 30°C, moisture content from 49% to 85 % , water-soluble carbohydrate (WSC) content ranging from 11.1 % to 17.5%, and with and without an addition of 0.25% formic acid. In all cases, delayed sealing resulted in poor-quality silage with high pH values and low …

Improving Hay Quality By Ammoniation, K J. Moore, V L. Lechtenberg, K S. Hendrix, J M. Hertel Jun 2026

Improving Hay Quality By Ammoniation, K J. Moore, V L. Lechtenberg, K S. Hendrix, J M. Hertel

IGC Proceedings (1977-2023)

Experiments were conducted to determine the effect of hay ammoniation on hay consumption and weight gain by steers when the hay was fed unsupplemented and supplemented with energy and protein. Mature orchardgrass (Dacrylis glomerata L.) hay was baled in early June 1979 and treated with anhydrous ammonia at 30 g/kg of hay. Seven weeks after treatment the hay was uncovered and allowed to aerate for 3 days. It was then fed to weanling steer calves weighing approximately 225 kg each. Similar hay baled from the same field but not ammoniated was fed to separate groups of steers. Both the treated …

Evaluations Of Low-Quality Roughages And Fibrous Cereal Grains Treated With Various Chemicals, G C. Fahey Jr, L L. Berger, M I. Mora, P J. Van Der Aar Jun 2026

Evaluations Of Low-Quality Roughages And Fibrous Cereal Grains Treated With Various Chemicals, G C. Fahey Jr, L L. Berger, M I. Mora, P J. Van Der Aar

IGC Proceedings (1977-2023)

Large improvements in the feeding value of low-quality roughages have resulted from treatment of them with various chemicals. Chemical treatment of grains may also be a potentially useful practice. The research reported here was designed (1) to determine how Chelating Metal Caustic Swelling (CMCS), a nontoxic, alkaline, aqueous reagent, compares with sodium hydroxide (NaOH) in enhancing in-vitro cellulose digestion (IVCD) of cornstalks (CS) (Zea mays) and soybean residues (SBR) (G!),cine max.), and (2) to evaluate the effects of NaOH and CMCS treatments of fibrous grains using in-situ techniques. CMCS or 7.5% NaOH solutions were added to CS or SBR at …

Effect Of Solvent Treatments On Intake And Digestibility Of Corn Stover, D M. Schaefer, M R. Ladisch, C H. Noller, V L. Lechtenberg

IGC Proceedings (1977-2023)

Treatment of crop residues with low levels of sodium hydroxide has been shown to improve organic-matter digestibility and animal performance. One objective of these experiments was to evaluate the effects of three treatments -water, sodium hydrox­ide, and chelating metal cellulose-swelling solution-on solubilization of cell-wall components in corn (Zea m£rys) stover. The two latter treatments were balanced for level of sodium hydroxide application, which was .3 .2 % of stover dry matter. The second objective was to determine the effects of these treatments on in-vitro and in-vivo digestibility as well as on consumption of corn stover. Twelve growing ram lambs were …

Factors Causing Greater In-Vitro Than In-Vivo Digestibility Of Sodium Hydroxide - Treated Roughages, L L. Berger, T J. Klopfenstein, R A. Britton

IGC Proceedings (1977-2023)

Research on sodium hydroxide (NaOH) treatment oflow-quality roughages generally indicates that in-vivo digestion is lower than in-vitro digestion. The purpose of this research was to identify factors that may cause less of the potentially digestible fiber to be digested in vivo than in vitro. Corn (Zea mays) cobs were raised to 60% moisture and treated to contain 0%, 2.5%, 5.0%, 7.5 % , and 10.0% NaOH. Lambs were fed diets containing 80% cobs and 20% supplement, giving a complete mixed diet con· taining 0%, 2.0%, 4.0%, 6.0%, and 8.0% NaOH. Five abomasally cannulated lambs were assigned to a 5 x …

Organic molecules exhibiting second-scale room-temperature phosphorescence (RTP) in the red/near-infrared are particularly rare because low-energy excited states that are characteristic of these chromophores are susceptible to nonradiative deactivation. Here, we observe second-scale red RTP from contorted hexabenzocoronene (cHBC) embedded in a rigid polymer. This RTP is uniquely efficient as approximately 23% of the steady-state photoluminescence originates from triplets. We propose that this efficient triplet generation stems from intersystem crossing (ISC) that outcompetes symmetry-forbidden fluorescence. Density functional theory and time-dependent density functional theory calculations suggest that ISC occurs from the lowest energy singlet state of cHBC into a nearly resonant triplet …

Endoplasmic Reticulum-Resident Α-Glucosidase Ii Drives Non-Small Cell Lung Cancer Progression Via Regulation Of Secretory Glycoproteins, Shike Wang, Na Ding, Angelo Chen, Derrick Cardin, Yuting Xu, Kate Grimley, William K. Russell, Jun Xu, Jonathan M. Kurie, Guan Yu Xiao, Xiaochao Tan

Markey Cancer Center Faculty Publications

Non-small cell lung cancer (NSCLC) remains a leading cause of cancer-related mortality worldwide, yet its molecular drivers are not fully defined. Emerging evidence highlights the importance of tumor-stroma interactions mediated by secreted glycoproteins. However, the mechanisms by which cancer cells regulate the secretion of these protumorigenic proteins remain largely unknown. Endoplasmic reticulum-resident (ER-resident) N-glycan-processing enzymes regulate proper protein folding, a prerequisite for glycoproteins to exit the ER and undergo secretion. By evaluating their prognostic significance in lung tumors and conducting functional screening in lung cancer cells, we identify α-glucosidase II (α-Glc II) as a key regulator of NSCLC progression. α-Glc …

We present a novel method for extracting the energy spectrum of ultracold neutrons from magnetically induced spin depolarization measurements using the n2EDM apparatus. This method is also used to exploit sensitivity to the storage properties of the materials used to trap ultracold neutrons, specifically, whether collisions are specular or diffuse. To do so, we utilize tomat simulation to map storage properties to correlation times of the ultracold neutrons to induced magnetic nonuniformities. We highlight the sensitivity of this new technique by comparing the two different storage chambers of the n2EDM experiment, which host different ultracold neutron energy spectra. This method …

Chemistry Faculty Publications

Scalable fabrication of uniform perovskite films is a critical bottleneck for large-area perovskite light-emitting diodes (PeLEDs), hindered by coffee-ring formation and heterogeneous crystallization upon scaling. Here, we report a multimodal solvent-engineering strategy enabling highly uniform films via ambient blade coating combined with vacuum-assisted solvent evaporation. Incorporating N-methyl-2-pyrrolidone (NMP) and acetonitrile (ACN) into a dimethylformamide (DMF)-based system synergistically modulates evaporation dynamics: It suppresses macroscopic solute segregation through Marangoni flow-induced redistribution, while tuning precursor coordination to regulate nucleation/phase conversion and promote radiatively efficient film formation. Consequently, the ternary formulation yields films with improved uniformity, reduced trap densities, and enhanced radiative efficiency. Near-infrared …

Patients with atypical variants of Alzheimer's disease (AD) often present at a younger age with predominantly non-amnestic impairments and a more aggressive disease course. Historically, individuals with atypical presentations have not been included in large-scale clinical trials, which typically focus on late-onset, sporadic amnestic-predominant AD. Consequently, treatment options and research efforts specific to atypical AD remain limited. The emergence of amyloid-targeting therapies that slow disease progression underscores these challenges, as evidence supporting their efficacy in early-onset amnestic and non-amnestic AD variants is scarce. This perspective article argues that atypical AD represents an excellent disease model for clinical trials and proposes …

The Problem: Transportability considerations are increasingly important to answer research questions in comparative effectiveness research (CER) to support the transfer of evidence on medicinal products across countries or settings. As drug development costs rise and healthcare systems and professionals face economic and resource pressures, leveraging existing data and evidence generated across borders or settings can improve efficiency and inform decisions in product development and decision-making (regulatory, health technology assessment [HTA] and clinical care). Differences in population characteristics, healthcare systems, and data availability, including coding discrepancies, may present significant challenges to the transportability of CER evidence. Without rigorous methodological approaches, the …

Kytc Crash Modification Factor Recommendation List Online Tool, William Staats, Reginald Souleyrette, Teng Alex Wang, Mohammad Zana Majidi

Kentucky Transportation Center Research Report

Transportation practitioners use crash modification factors/functions (CMFs) to calculate the number of crashes expected once a countermeasure has been implemented. When evaluating design alternatives, CMFs can be used in conjunction with safety performance functions (SPFs) to derive crash predictions. The Federal Highway Administration (FHWA) maintains the CMF Clearinghouse as a repository for CMFs. Contributions are submitted by researchers across the U.S., Canada, and throughout the world. Typically, individual countermeasures are associated with multiple CMFs. Some CMFs only apply to a specific facility or crash types. CMF quality varies, and some only apply to a specific facility and/or crash types, regions, …

Higher Uniformity Of Arithmetic Functions In Short Intervals Ii. Almost All Intervals, Kaisa Matomäki, Maksym Radziwiłł, Xuancheng Shao, Terence Tao, Joni Teräväinen

Mathematics Faculty Publications

We study higher uniformity properties of the von Mangoldt function Λ, the Möbius function μ, and the divisor functions dk on short intervals (x,x+H] for almost all x∈[X,2X]. Let Λ♯ and dk♯ be suitable approximants of Λ and dk, G/Γ a filtered nilmanifold, and F:G/Γ→C a Lipschitz function. Then our results imply for instance that when X1/3+ε≤H≤X we have, for almost all x∈[X,2X], (Formula presented.) for any fixed A>0, and that when Xε≤H≤X we have, for almost all x∈[X,2X], (Formula presented.) As a consequence, we show that the short interval Gowers norms ∥Λ−Λ♯∥Us(X,X+H] and ∥dk−dk♯∥Us(X,X+H] are also asymptotically small …

Development Of Kytc’S Context Classification Network, Jill Asher, Megan White, Eric Green, Christopher Van Dyke

Kentucky Transportation Center Research Report

Transportation agencies have adopted context-based classification systems that classify roadways based on the surrounding environment and user types. This offers a more comprehensive and multimodal perspective than traditional functional classification. While the Kentucky Transportation Cabinet (KYTC) has begun using project-level context classification, the agency will benefit from introducing network-level context classification. This will improve guidance, enhance project prioritization, and support the development of projects that better address the needs of all users. Responding to this need, Kentucky Transportation Center (KTC) researchers, in conjunction with KYTC staff, created a GIS-based model to build a context classification network that covers all state-maintained …

Holographic Description Of 4d Maxwell Theories And Their Code-Based Ensembles, Ahmed Barbar, Anatoly Dymarsky, Alfred Shapere Jun 2026

Holographic Description Of 4d Maxwell Theories And Their Code-Based Ensembles, Ahmed Barbar, Anatoly Dymarsky, Alfred Shapere

Physics and Astronomy Faculty Publications

We formulate a precise holographic duality between an ensemble of 4d U(1)g Maxwell theories living on a spin four-manifold M4 and a topological Abelian BF-type 2-form theory of level N, summed over all five-manifolds with boundary M4. The elements of the boundary ensemble are Abelian gauge theories specified by self-dual symplectic codes over ℤN, that parameterize topological boundary conditions in the 5d TQFT. Similarly, the equivalence classes of topologies distinguished by the 5d theory are parameterized by orthogonal self-dual codes. Hence the holographic duality can be reformulated in the language of quantum stabilizer codes. …

We present detections of auroral emission lines of [O iii], [O ii], [S iii], and [S ii] in deep JWST/NIRSpec spectroscopy for 41 star-forming galaxies at z = 1.4–7.2 from the AURORA survey. We combine these new observations with 98 star-forming galaxies at z = 1.3–10.6 with detected auroral lines drawn from the literature to form a sample of 139 high-redshift galaxies with robust electron temperature and direct-method oxygen abundance determinations. This sample notably covers a wider dynamic range in metallicity than previous work, spanning 0.02–0.9 Z⊙. We calibrate empirical relations between 19 emission-line ratios and oxygen abundance, …

We present deep, medium-resolution (Formula presented) m JWST/NIRSpec spectroscopy for 14 quiescent galaxies at (Formula presented) with (Formula presented), obtained as part of the EXCELS survey. We perform a complete re-reduction of these data, including a custom optimal-extraction approach to combat the spectral ‘wiggles’ that result from undersampling of the NIRSpec spatial PSF. We constrain the star-formation histories and stellar metallicities of these objects via full-spectral fitting, finding a clear stellar age versus stellar mass correlation, in which more massive galaxies assembled their stellar mass at earlier times. This confirms spectroscopically that the archaeological ‘downsizing’ trend was already in place …

A fundamental understanding of landslide evolution requires characterizing how deformation localizes within the sliding mass, as these non-homogeneous zones provide crucial insights into how destabilization initiates, failure surfaces develop, and the overall kinematic behavior evolves. While traditional analysis often assumes uniform movement, this study presents a methodology to quantify intricate patterns of surface deformation at a fine scale, allowing for the direct analysis of localization behavior. By applying strain tensor analysis to high-resolution displacement fields derived from multi-temporal Uncrewed Aerial Vehicle-Light Detection and Ranging (UAV-lidar) and Structure from Motion (SfM) surveys, we compute the divergence, gradient, and curl fields for …

Accurate inferences of diversification and evolutionary processes depend on knowing how many independently evolving lineages exist within nominally widespread taxa. Uncertainty in lineage number and composition also limits our ability to meaningfully prioritise conservation efforts. Addressing these knowledge gaps requires frameworks that sequentially identify distinct lineages, assess mechanisms that contribute to their divergence, and quantify spatial and environmental determinants of their genomic diversity. With these goals in mind, we apply whole-genome, ecological, and morphological analyses to the American rubyspot damselfly (Hetaerina americana), a widespread and well-studied North American insect that has been long regarded as a single species of least …
