description: Minimizing the risk of antibiotic resistant organisms and antibiotic residues in dairy and dairy-beef products is a topic of nationwide interest. Our long term goal is to achieve this objective, based on decreasing unnecessary antibiotic use on dairies. To design an effective outreach program on judicious use of antibiotics, it is imperative to describe the actual practices on dairies. Antibiotic therapy on dairies is mostly used on post-partum and mastitic cows. On most of large California dairies, dairy employees are ultimately responsible for sick cow identification, disease diagnose, and treatment administration. Thus, to understand how antibiotics are used on dairies, researchers need to work directly with the individuals ultimately administering antibiotics to cows. The objective of this study is to describe identification techniques and treatments decisions for mastitic cows.

description: Interaction with a thermal environment decoheres the quantum state of a mechanical oscillator. When the interaction is sufficiently strong, such that more than one thermal phonon is introduced within a period of oscillation, quantum coherent oscillations are prevented. This is generally thought to preclude a wide range of quantum protocols. Here, we introduce a pulsed optomechanical protocol that allows ground state cooling, general linear quantum non-demolition measurements, optomechanical state swaps, and quantum state preparation and tomography without requiring quantum coherent oscillations. Finally we show how the protocol can break the usual thermal limit for sensing of impulse forces.

description: No abstracts are to be cited without prior reference to the author.Seasonal appearances of tidal mixing fronts (TMF) induce structures in the water column where physical and biological properties change within very small scales. Abundance, ingestion rates and condition of sprat and sardine larvae, sampled across a TMF in the German Bight (Fig. 1), are related to the larval prey field. The role of larval starvation for recruitment is discussed.

description: Deep learning has shown promising results in many machine learning applications. The hierarchical feature representation built by deep networks enable compact and precise encoding of the data. A kernel analysis of the trained deep networks demonstrated that with deeper layers, more simple and more accurate data representations are obtained. In this paper, we propose an approach for layer-wise training of a deep network for the supervised classification task. A transformation matrix of each layer is obtained by solving an optimization aimed at a better representation where a subsequent layer builds its representation on the top of the features produced by a previous layer. We compared the performance of our approach with a DNN trained using back-propagation which has same architecture as ours. Experimental results on the real image datasets demonstrate efficacy of our approach. We also performed kernel analysis of layer representations to validate the claim of better feature encoding.

description: In recent works, a construction was proposed resulting emergent universes inside black holes. This result can be obtained from a 4D black hole embedded in a 5D space time with the fifth dimension compactified on a circle [0, 2] (0 and 2 are identified) such that the two branes are at 0 and 1. In the present work, we study this setup by deriving particles equations of motion in the new universes, based on redefining energy and angular momentum. This leads to disappearance of the singularity in centres of black holes in classical General Relativity.

description: The methane-based material (H$_2$)$_4$CH$_4$, also called H4M for short, is in essence a methane molecule with 4 physisorbed H$_2$ molecules. While H4M has exceptionally high hydrogen storage densities when it forms a molecular solid, unfortunately, this solid is only stable at impractically high pressures and/or low temperatures. To overcome this limitation, we show through simulations that longer alkanes (methane is the shortest alkane) also form stable structures that still physisorb 4 H$_2$ molecules per carbon atom; we call those structures H4-alkanes. We further show via molecular dynamics simulations that the stability field of molecular solids formed from H4-alkanes increases remarkably with chain length compared to H4M, just as it does for regular alkanes. From our simulations of H4-alkanes with lengths 1, 4, 10, and 20, we see that e.g. for the 20-carbon the stability field is doubled at higher pressures. While even longer chains show only insignificant improvements, we discuss various other options to stabilize H4-alkanes more. Our proof-of-principle results lay the groundwork to show that H4-alkanes can become viable hydrogen storage materials.

description: The large size of dairy operations in California (average herd size of 1,200 cows/dairy) creates large demands for hired help. Most dairy employees on California dairies are of Hispanic ethnicity with little formal training on animal husbandry. Communication issues on these dairies have been documented between upper management and individuals administering antibiotic treatments to calves. This could result on treatment protocols (as decided by veterinarians and owners) not being followed by the dairy employee. The objective was to describe the involvement of owners and veterinarians on fresh cow evaluations, and to identify who the fresh cow evaluators requested advice from. The identification of influencers is key to design an effective outreach program.

description: Residual gas in disks around young stars can spin down stars, circularize the orbits of terrestrial planets, and whisk away the dusty debris that is expected to serve as a signpost of terrestrial planet formation. We have carried out a sensitive search for residual gas and dust in the terrestrial planet region surrounding young stars ranging in age from a few Myr to ~10 Myr in age. Using high resolution 4.7 micron spectra of transition objects and weak T Tauri stars, we searched for weak continuum excesses and CO fundamental emission, after making a careful correction for the stellar contribution to the observed spectrum. We find that the CO emission from transition objects is weaker and located further from the star than CO emission from non-transition T Tauri stars with similar stellar accretion rates. The difference is possibly the result of chemical and/or dynamical effects (i.e., a low CO abundance or close-in low-mass planets). The weak T Tauri stars show no CO fundamental emission down to low flux levels (5 x 10^(-20) - 10^{-18} W/m^2). We illustrate how our results can be used to constrain the residual disk gas content in these systems and discuss their potential implications for star and planet formation.

description: Collaborative filtering (CF) is one of the most successful and fundamental techniques in recommendation systems. In recent years, Graph Neural Network (GNN)-based CF models, such as NGCF [31], LightGCN [10] and GTN [9] have achieved tremendous success and significantly advanced the state-of-the-art. While there is a rich literature of such works using advanced models for learning user and item representations separately, item recommendation is essentially a link prediction problem between users and items. Furthermore, while there have been early works employing link prediction for collaborative filtering [5, 6], this trend has largely given way to works focused on aggregating information from user and item nodes, rather than modeling links directly. In this paper, we propose a new linkage (connectivity) score for bipartite graphs, generalizing multiple standard link prediction methods. We combine this new score with an iterative degree update process in the user-item interaction bipartite graph to exploit local graph structures without any node modeling. The result is a simple, non-deep learning model with only six learnable parameters. Despite its simplicity, we demonstrate our approach significantly outperforms existing state-of-the-art GNN-based CF approaches on four widely used benchmarks. In particular, on Amazon-Book, we demonstrate an over 60% improvement for both Recall and NDCG. We hope our work would invite the community to revisit the link prediction aspect of collaborative filtering, where significant performance gains could be achieved through aligning link prediction with item recommendations.

description: A new abietane diterpenoid, tripterregeline A (1), together with six known diterpenoids (2–7), were isolated from the roots of Tripterygium regelii. The structure of 1 was elucidated by extensive spectroscopic methods and the known compounds were identified by comparison with data reported in the literature. All isolated compounds were evaluated for their cytotoxicities against five human cancer cell lines: HL-60, SMMC-7721, A-549, MCF-7 and SW480 in vitro. Compounds 1–7 showed significant inhibitory effects against various human cancer cell lines with IC50 values ranging from 0.58 to 21.06 μM.

description: Dietary characteristics of close-up (CU) are critical for a good transition period. The recipe fed should be as close as possible to the formulation provided by the nutritionist. The fed ration often differs from the formulated ration as a result of feeder errors during CU recipe preparation, uncertainties in dry matter (DM) content, and nutrient composition of the ingredients. The objective of this study is to improve feed efficiency and decrease variation while preparing the CU recipe on dairy farms.

description: High-pressure neutron powder diffraction, muon-spin rotation and magnetization studies of the structural, magnetic and the superconducting properties of the Ce-underdoped superconducting (SC) electron-doped cuprate system T'-Pr_1.3-xLa_0.7Ce_xCuO_4 with x = 0.1 are reported. A strong reduction of the lattice constants a and c is observed under pressure. However, no indication of any pressure induced phase transition from T' to T structure is observed up to the maximum applied pressure of p = 11 GPa. Large and non-linear increase of the short-range magnetic order temperature T_so in T'-Pr_1.3-xLa_0.7Ce_xCuO_4 (x = 0.1) was observed under pressure. Simultaneously pressure causes a non-linear decrease of the SC transition temperature T_c. All these experiments establish the short-range magnetic order as an intrinsic and a new competing phase in SC T'-Pr_1.2La_0.7Ce_0.1CuO_4. The observed pressure effects may be interpreted in terms of the improved nesting conditions through the reduction of the in-plane and out-of-plane lattice constants upon hydrostatic pressure.

description: Genus Paris mainly distributed in Asia and served as traditional ethnobotanical medicine in China, India, and Nepal. The main aim of this study was to review ethnic minorities medicinal records for Paris in China, the Chinese patent medicines based on Paris materials and the authentication and quality evaluation of Paris based on two parts of analytical technologies and data analysis. This article reviews approximately 100 articles from 1980 to 2019 published on the research of genus Paris materials and their Chinese patent medicines. Additionally, local books were also searched. Five major kinds of chemical techniques have been applied to authentication and quality assessment of Paris and among them, chromatography was the most widely used one, and DNA barcoding technique was the most worth further study. Additionally, more than 70% of the research studies were analyzed by unsupervised pattern-recognition techniques combined with analytical technologies such as spectroscopy. Meanwhile, the data fusion strategy with higher classification ability combined multiple supervised pattern-recognition techniques have been gradually applied to authentication assessment. The optimal analytical technologies and methods applied to Paris qualities for authentication and quality evaluation are greatly important, which could promote the development and utilization for ethnomedicines of Paris.

description: No abstracts are to be cited without prior reference to the author.Growth of larval cod is largely determined by body size and environmental conditions such as temperature, prey availability, light and turbulence. In order to investigate the effect of these processes on larval and juvenile cod, an Individual-Based Model (IBM) has been developed. Using data from a macrocosm study on the growth of Atlantic cod (Gadus morhua), we are able to evaluate model predictions with observations. Temporal variations in prey abundance, prey size and temperature from the experiment are used as forcing of the IBM and a variety of variables from the simulations are compared with experiment data, i.e. growth rate of larvae in the experiment. It appears that the larvae is unable to sustain the potential (size- and temperature-limited) growth, then growth must be a function of food ingestion.

description: A new class of degradable polymers—AABB-type polydepsipeptides (PDPs) composed of four building blocks—naturally occurring α-amino and α-hydroxy acids, fatty diol and dicarboxylic acid were synthesized for the first time. For the synthesis of novel PDPs, new diester diacids—O,O′-diacyl-bis-glycolic acids (DAGAs) were prepared by interaction of diacid chlorides with glycolic acid and then they were transformed into activated di-p-nitrophenyl esters (DAGN), which were further used in solution active polycondensation (SAP) as bis-electrophilic monomers. High-molecular-weight (Mw up to 66.5 kDa) AABB PDPs having film-forming properties were obtained by reacting activated diesters with two different bis-nucleophilic diester-diamine monomers—di-p-toluenesulfonic acid salts of bis-(l-phenylalanine)-1,6-hexylene diester, F6, and bis-(l-leucine)-1,6-hexylene diester, L6. The developed synthetic strategy was also found to be suitable for the synthesis of so called 3M poly(ester amide)s (3M PEAs) by SAP of the activated diesters with 1,6-hexanediamine (HDA). The suggested approach allows the synthesis of the functional AABB PDPs and 3M-type PEAs containing pendant functional groups (OH or COOH) suitable for subsequent modifications. Nonspecific in vitro degradation (hydrolysis) study of selected samples of AABB PDPs showed enhanced degradation rates compared to regular amino acid based PEAs. The new polymers are promising for various biomedical applications.

description: Ketosis is an important metabolic disease in transition cows, associated with decreased milk production, impaired reproductive performance, and abomasal displacements. Cows with blood beta hydroxybutyrate (BHBA) concentrations greater than 14.4 mg/dL (1.4 mmol/L) are considered to be ketotic (Duffield et al). Producers or veterinarians may measure blood BHBA levels in individual sick cows (diagnostic purposes) or may periodically test representative groups of fresh cows to estimate the herd prevalence of ketosis (monitoring purposes). However, there are disadvantages to currently available tests. Though considered the gold standard, submitting serum samples to a veterinary diagnostic laboratory for BHBA analysis is inconvenient and expensive, and the delay in reporting does not lend itself as an individual animal diagnostic test. Conversely, and though they are inexpensive, rapid, and easy to use, available cow-side urine and milk ketone tests have been reported to have lower sensitivity and specificity (Carrier et al) and rely on visual interpretation of color change. Ideally, the industry would have an accurate, rapid, convenient, and inexpensive cow-side test to measure blood BHBA levels in cows. The objective of this study was to evaluate the accuracy of an electronic hand held BHBA meter, designed to measure blood BHBA in human diabetics, for cow-side use in dairy herds.

description: Polymerization of norbornene was carried using a (MC) and two dinuclear (DC1 and DC2) α–diimine Ni-based catalysts under controlled conditions. The structure of dinuclear catalysts had a difference on the ortho- and para position (2,4.6-trimethyl group for DC1 and 2, 6-isopropyl group for DC2). DC2 catalyst through synergistic effects exhibited higher productivity (1.3 × 106 g/mol Ni) in comparison to DC1 catalyst (1.0 × 106 g/mol Ni) and MC catalyst (0.8 × 106 g/mol Ni). Moreover, molecular weights of the polynorbornene (PN) made by DC2 catalyst (Mw = 9.0 × 105 g/mol and Mv = 5.1 × 105 g/mol) were greater than the sample obtained by DC1 (Mv = 3.1 × 105 g/mol) and MC (Mw = 4.7 × 105 g/mol and Mv = 2.4 × 105 g/mol). Reaction parameters especially polymerization temperature showed a significant impact on catalyst productivity and molecular weight of the samples. Thermal analysis including DSC, DMTA and TGA employed to characterize the PNs and revealed that the sample obtained by DC2 catalyst had a much uniform and stereoregularity in microstructure, while for MC, results were slightly different. Based on this, the Tg of the PN made by the DC2 catalyst was distinctive, and the DTGA curve was unimodal. The microstructural study of PNs was carried out using 13C NMR and confirmed the observed properties.

We put the method in historical context and discuss recent developments, taking the viewpoint of a general framework based on the integral equations for the electric field. We review both the theory of the DDA and its numerical aspects, the latter being of critical importance for any practical application of the method. Finally, the position of the DDA among other methods of light scattering simulation is shown and possible future developments are discussed.

description: Feeding rations with low dietary cation-anion difference (DCAD) to dairy cows during late gestation is a commonly used strategy in large herds to prevent periparturient hypocalcemia. Although the efficacy of low DCAD rations in reducing the incidence of clinical hypocalcemia is well documented, it is not clear whether the ensuing metabolic acidosis is associated with deleterious side effects during the transition period. The objective of the study presented here was to determine the effect of fully compensated metabolic acidosis on calcium and phosphorus homeostasis, insulin responsiveness, and insulin sensitivity as well as on indices for protein metabolism.

description: Marine micro-organisms have been proven to be excellent sources of bioactive compounds against HIV-1. Several natural products obtained from marine-derived Aspergillus fungi were screened for their activities to inhibit HIV-1 infection. Penicillixanthone A (PXA), a natural xanthone dimer from jellyfish-derived fungus Aspergillus fumigates, displayed potent anti-HIV-1 activity by inhibiting infection against CCR5-tropic HIV-1 SF162 and CXCR4-tropic HIV-1 NL4-3, with IC50 of 0.36 and 0.26 μM, respectively. Molecular docking study was conducted to understand the possible binding mode of PXA with the CCR5/CXCR4. The results revealed that, the marine-derived PXA, as a CCR5/CXCR4 dual-coreceptor antagonist, presents a new type of potential lead product for the development of anti-HIV therapeutics.

description: No abstracts are to be cited without prior reference to the author.The dynamics of the water is of great importance for fish in their early life stages, when passive transportation prevails over their active movement. The effect of dynamic processes on eggs starts right after spawning. The model of eggs ascent from the spawning depths to the surface and hydrodynamic model for the Barents Sea were applied to study this effect. The analysis of spatial distribution and estimation of cod eggs and larvae abundance index is performed basing on the data of ichthyoplankton surveys in the area of Lofoten shallow waters for 1959-1993. The conditions of eggs ascent, variability of fluxes in different current brunches and the results of further transport of ichthyoplankton in the years different in abundance of cod year-classes during the period under study were compared. It was found that oceanographic conditions in spawning time vary significantly for years with different in abundance cod year-classes. The most abundant year-classes occurred in years with high heat content when the water density is low. Under these conditions eggs rise slowly, which to some extend allows them to adapt to new thermal environment and eggs do not undergo through large temperature changes while coming to the surface. The calculation of water fluxes showed that poor year-classes of cod occurred in the years when the Norwegian current was weakened, drift component of the Spitsbergen current had positive values and that of the North Cape was negative. Rich year-classes of cod occurred in the years when the Norwegian current was strengthened, drift component of the North Cape current had positive values and that of the Spitsbergen was negative or poorly positive.

description: Serum amyloid-A (SAA) and haptoglobin are positive acute phase proteins in cattle that are produced by the liver in response to endogenous release of glucocorticoids and pro-inflammatory cytokines. Recent studies have indicated that SAA provides a more sensitive test of inflammation and bacterial infection in cattle than hematological analysis and clinical examination. Albumin is a negative acute phase protein in cattle. We hypothesized that the serum concentration of SAA and haptoglobin would be increased, and the serum concentration of albumin would be decreased, in cows with left displaced abomasum (LDA), right displaced abomasum (RDA), or abomasal volvulus (AV), relative to healthy dairy cows. The basis for our hypothesis was the presence of nutritional stress in cattle with LDA, RDA, and AV, as well as the presence of peritonitis in some cattle with AV. We confined our investigation to cattle that did not have clinical evidence of inflammation or bacterial infection, such as mastitis, metritis, or pneumonia, in order to minimize the confounding effect of clinical disease on the acute phase response.

description: Firstly, polystyrene (PS)-grafted silica (SiO2) particles were prepared by means of “grafting from”, and then chloromethylated with 1,4-dichloromethoxybutane to obtain chloromethylstyrene (CMPS)-grafted particles CMPS/SiO2. Finally, salicylhydroxamic acid (SHA) was bonded to CMPS/SiO2 particles by nucleophilic substitution reaction, so as to prepare SHA-functionalized adsorption materials SHA-PS/SiO2. The adsorption characteristics of them for quercetin are studied in depth by using static and dynamic methods, and the adsorption thermodynamics is investigated. The experimental results show that SHA-PS/SiO2 has good adsorption properties for quercetin with a very great adsorption capacity (1.5 mmol/g) due to the synergy of various interactions between SHA-PS/SiO2 and quercetin, such as π–π stack, π-type hydrogen bond, conventional hydrogen bond and hydrophobic interaction. The adsorption isotherm data matches the Langmuir model. The adsorption process of SHA-PS/SiO2 toward quercetin is exothermic and driven by enthalpy. Besides, the adsorption materials still have good reusability.

description: We report a detailed study of the magnetization modulus as a function of temperature and applied magnetic field under varying angle in Sr$_{4}$Ru$_{3}$O$_{10}$ close to the metamagnetic transition at $H_{c}\backsimeq 2.5\,$T for $H \perp c$. We confirm that the double-feature at $H_{c}$ is robust without further splitting for temperatures below 1.8 K down to 0.48 K. The metamagnetism in Sr$_{4}$Ru$_{3}$O$_{10}$ is accompanied by a reduction of the magnetic moment in the plane of rotation and large field-hysteretic behavior. The double anomaly shifts to higher fields by rotating the field from $H\,\perp \,c$ to $H\,\parallel\,c$. We compare our experimental findings with numerical simulations based on spin reorientation models caused by intrinsic magnetocrystalline anisotropy and Zeeman effect. Crystal anisotropy is able to explain a metamagnetic transition in the ferromagnetic ordered system Sr$_{4}$Ru$_{3}$O$_{10}$, but a Dzyaloshinskii-Moriya term is crucial to account for a reduction of the magnetic moment as discovered in the experiments.

description: The importance of adequate passive transfer (APT, IgG ≥ 10 mg/mL at 24-48 h) of immunoglobulin (lg) for newborn calves is widely known in the dairy industry. Failure of passive transfer (FPT) is associated with increased risk of morbidity, mortality, reduced growth rate, and decreased production at first lactation. The gold standard test is measurement of serum IgG concentrations in an accredited veterinary laboratory using either RID or turbidimetric immunoassay (TIA) methods. Laboratory measures are accurate but expensive ($6 to $12 per sample), plus take time to ship samples and wait for results. A common on-farm test is to measure serum total protein (TP) concentrations using a hand held refractometer to indirectly predict serum IgG concentrations. This approach is inexpensive and rapid but is less accurate than direct IgG measurement in a laboratory. Calloway and others (2002) reported that serum TP concentrations of 5.0 g/dL had a sensitivity and specificity of 0.89 and 0.84, respectively, in detecting calves with FPT. Ideally, the industry would have available an accurate, rapid, convenient, and inexpensive calf-side test to measure serum IgG concentrations. The Midland BioProducts QTII™ Bovine Serum IgG test is a portable hand-held chemistry analyzer that works on the principle of a TIA method (Midland BioProducts Inc., Boone, IA). The chemistry analyzer weighs about 2 lb (0.91 kg), is about the size of a 1 L bottle and costs $1,950.00 as a one time purchase. Test kits are available in sets of 5 at approx. $7 .50 per test for the bovine species IgG. Test kits are also available for other bovine analytes including serum albumin, total protein, calcium, magnesium and phosphorus. It takes approx. six minutes to run one test. The objective of this study was to describe the test characteristics of the MBC QTII™ Bovine Serum IgG test.

description: Few studies report long term information on how cattle perform following rumen surgery. The purpose of this study was to gather information from medical records of cattle having rumenotomy or rumenostomy to determine how these cattle functioned following surgery. The objective of the study was to determine if there were any preoperative factors (clinical signs, radiographic findings, laboratory values, etc.) that were correlated with outcome.

description: Use of refractometers to measure serum total protein (TP, g/dl) is a good method for monitoring passive transfer of IgG in groups of calves. Calloway and others (2002) reported that a serum TP concentrations of 5.0 or 5.2 g/dl most accurately predicted adequate passive transfer, defined as serum IgG of 10 mg/mL. The relationship between serum TP and IgG has been determined for calves fed maternal colostrum (MC), but not for calves fed whole colostrum derived colostrum replacers (CR). The objective of this study is to describe the relationship between serum TP (g/dl) and IgG concentrations (mg/mL) at 24 hours of age in calves fed whole colostrum derived CR vs calves fed raw MC.

description: The correlation holography reconstructs 3D objects as a distribution of two-point correlation of the random field detected by two dimensional detector arrays. Here, we describe a hybrid method, a combination of optical and computational channels, to reconstruct the objects from only a single pixel detector. An experimental arrangement is proposed and as a first step to realize the technique, we have simulated the experimental model for both scalar and vectorial objects. Proposed technique affords background free imaging with 3D capability.

description: Microorganisms are used to alleviate heavy metal stress in plants cultivated in contaminated fields. However, the relevant mechanisms have been rarely explored. The goal of this study was to investigate effects of arbuscular mycorrhizal fungus Funneliformis mosseae and two Cd-resistant bacterial strains (Enterobacter sp. EG16 and Enterobacter ludwigii DJ3) on growth and Cd tolerance of tomato when applied with different inoculation strategies (single or dual) and Cd concentrations (50 and 100 mg kg−1). Better plant growth was observed in mycorrhizal alone or combined treatments. In F. mosseae and EG16 co-inoculation treatment, shoot and root dry weight were 119–154% and 91–173% higher than those of the control, respectively. Higher bacterial and mycorrhizal colonization rate and root Cd concentration were also found in this treatment. However, the decrease of shoot Cd concentration and translocation factor values indicated this treatment was effective in improving Cd tolerance of the host plants. In addition, the increase in soil pH and decline in bioavailable Cd in the rhizosphere might be partly involved in reduction of Cd accumulation in plants. Our results suggest that co-inoculation with suitable microorganisms is important in plant growth and tolerance to Cd in Cd-contaminated soil.

description: This paper examines the addition of “asexuality” to the Library of Congress Subject Headings as a case study from which to examine the critical cataloging movement. Beginning with a review of some of the theoretical and practical issues around subject access for minoritized and marginalized sexualities, this paper then contextualizes, historicizes, and introduces the critical cataloging movement to the literature, situating it within a larger and longer history of radical cataloging. It will define critical cataloging as a social justice-oriented style of radical cataloging that places an emphasis on radical empathy, outreach work, and recognizes the importance of information maintenance and care. This paper introduces the concept of “catalogic warrant” to characterize the process of “reading” the catalog to examine the harm or benefit of terms on users and the wider library community.
Historic behaviour for nonautonomous contraction mappings

description: We consider a parametrised perturbation of a $\mathscr C^r$ diffeomorphism on a closed smooth Riemannian manifold with $r\geq 1$, modeled by nonautonomous dynamical systems. A point without time averages for a (nonautonomous) dynamical system is said to have historic behaviour. It is known that for any $\mathscr C^r$ diffeomorphism, the observability of historic behaviour, in the sense of the existence of a positive Lebesgue measure set consisting of points with historic behaviour, disappears under absolutely continuous, independent and identically distributed (i.i.d.) noise. On contrast, we show that the observability of historic behaviour can appear by a non-i.i.d. noise: we consider a contraction mapping for which the set of points with historic behaviour is of zero Lebesgue measure and provide an absolutely continuous, non-i.i.d. noise under which the set of points with historic behaviour is of positive Lebesgue measure.
