title: Methods for marker assisted breeding in Octoploid Strawberry (Fragaria × ananassa)
Creators: name: He, Joe
Publisher: name: University of Reading
Year: 2021

description: Strawberry is an economically important crop with global and UK production on an upwards trend. Strawberry breeding efforts attempt to generate novel varieties that have increased yields, resistance to pathogens, good eating quality and high nutritional content. Genomic prediction (GP) is an advanced marker assisted prediction (MAP) technique that makes predictions about agronomically important traits in crops. Three areas of improvement were identified to assist commercial deployment of GP for strawberry. Breeding efforts currently rely primarily on visual and mechanical measurement of plant phenotypes, which is slow, imprecise and liable to human biases. A strawberry phenotyping platform was developed that captured images from 360° around the straw�berry fruit to generate 3D representations. Seven fruit quality traits were calculated from the representations, which showed good concordance with manual measurements. Deployment of the system could lower phenotyping costs, increase throughput, increase precision and thus improve GP accuracy. Current genotyping approaches for dense marker panels in strawberry are too expen�sive for commercial deployment. A rational design process was implemented to generate amplicon sets that would genotype a panel of markers to maximise information for GP, with scalability to accommodate resources available to different breeding programmes. The design process failed to generate marker information due to unexpected interaction in the multiplexed PCR reaction. The relative effectiveness of phenotypic prediction and MAP in strawberries is unclear. Moreover, existing models of GP in strawberry do not represent all the traits of interest to breeders. Between years predictions of 15 fruit quality traits were implemented using phenotype only, traditional MAP (tMAP) and GP models. GP had similar selection accuracy compared to phenotype only prediction, but tMAP performed significantly worse than the other models. It was concluded that GP would likely yield benefits to strawberry breeding in the context of speed breeding.

description: The long-standing conjectures of the optimality of Gaussian inputs for Gaussian channel and Gaussian additivity are solved for a broad class of covariant or contravariant Bosonic Gaussian channels (which includes in particular thermal, additive classical noise, and amplifier channels) restricting to the class of states with finite second moments. We show that the vacuum is the input state which minimizes the entropy at the output of such channels. This allows us to show also that the classical capacity of these channels (under the input energy constraint) is additive and is achieved by Gaussian encodings.

A Fully Nonparametric Modelling Approach to Binary Regression

Year: 2014

subject: FOS: Computer and information sciences

description: We propose a general nonparametric Bayesian framework for binary regression, which is built from modeling for the joint response-covariate distribution. The observed binary responses are assumed to arise from underlying continuous random variables through discretization, and we model the joint distribution of these latent responses and the covariates using a Dirichlet process mixture of multivariate normals. We show that the kernel of the induced mixture model for the observed data is identifiable upon a restriction on the latent variables. To allow for appropriate dependence structure while facilitating identifiability, we use a square-root-free Cholesky decomposition of the covariance matrix in the normal mixture kernel. In addition to allowing for the necessary restriction, this modeling strategy provides substantial simplifications in implementation of Markov chain Monte Carlo posterior simulation. We present two data examples taken from areas for which the methodology is especially well suited. In particular, the first example involves estimation of relationships between environmental variables, and the second develops inference for natural selection surfaces in evolutionary biology. Finally, we discuss extensions to regression settings with multivariate ordinal responses.

description: Flat-space limit is well-defined for asymptotically AdS spacetimes written in coordinates called the BMS gauge. For the three-dimensional Einstein gravity with a negative cosmological constant, we calculate the quasi-local energy momentum tensor in the BMS gauge and take its flat-space limit. In defining the flat-space limit, we use the BMS/GCA correspondence which is a duality between gravity in flat-spacetime and a field theory with Galilean conformal symmetry. The resulting stress tensor reproduces correct values for conserved charges of three dimensional asymptotically flat solutions. We show that the conservation relation of the flat-space energy-momentum tensor is given by an ultra-relativistic contraction of its relativistic counterpart. The conservation equations correspond to Einstein equation for the flat metric written in the BMS gauge. Our results provide further checks for the proposal that the holographic dual of asymptotically flat spacetimes is a field theory with Galilean conformal symmetry.

description: Exchange of orbital angular momentum between Laguerre-Gaussian beam of light and center-of-mass motion of an atom or molecule is well known. We show that orbital angular momentum of light can also be transferred to the internal electronic or rotational motion of an atom or a molecule provided the internal and center-of-mass motions are coupled. However, this transfer does not happen directly to the internal motion, but via center-of-mass motion. If atoms or molecules are cooled down to recoil limit then an exchange of angular momentum between the quantized center-of-mass motion and the internal motion is possible during interaction of cold atoms or molecules with Laguerre-Gaussian beam. The orientation of the exchanged angular momentum is determined by the sign of the winding number of Laguerre-Gaussian beam. We have presented selective results of numerical calculations for the quadrupole transition rates in interaction of Laguerre-Gaussian beam with an atomic Bose-Einstein condensate to illustrate the underlying mechanism of light orbital angular momentum transfer. We discuss how the alignment of diatomic molecules will facilitate to explore the effects of light orbital angular momentum on electronic motion of molecules.

description: We describe the behavior of a system of fermionic atoms loaded in a bipartite one-dimensional optical lattice that is under the action of an external time-periodic driving force. By using Floquet theory, an effective model with renormalized hopping coefficients is derived. The insulating behavior characterizing the system at half-filling in the absence of driving is dynamically suppressed and for particular values of the driving parameter the system becomes either a standard metal or an unconventional metal with four Fermi points. We use the bosonization technique to investigate the effect of on-site Hubbard interactions on the four Fermi-point metal-insulator phase transition. Attractive interactions are expected to enlarge the regime of parameters where the unconventional metallic phase arises, whereas repulsive interactions reduce it. This metallic phase is known to be a Luther-Emery liquid (spin gapped metal) for both, repulsive and attractive interactions, contrarily to the usual Hubbard model which exhibits a Mott insulator phase for repulsive interactions. Ultracold fermions in driven one-dimensional bipartite optical lattices provide an interesting platform for the realization of this long studied four Fermi-point unconventional metal.

An annihilator formula is established, which is used to characterise the weak* closed subspaces of B(L^2(G)) which are invariant under both Schur multipliers and a canonical action of M(G) on B(L^2(G)) via completely bounded maps. We study the special cases of extremal ideals with a given null set and, for a large class of groups, we establish a link between relative spectral synthesis and relative operator synthesis.

description: We introduce a quantum Monte Carlo algorithm to measure the Rényi entanglement entropies in systems of interacting bosons in the continuum. This approach is based on a path integral ground state method that can be applied to interacting itinerant bosons in any spatial dimension with direct relevance to experimental systems of quantum fluids. We demonstrate how it may be used to compute spatial mode entanglement, particle partitioned entanglement, and the entanglement of particles, providing insights into quantum correlations generated by fluctuations, indistinguishability and interactions. We present proof-of-principle calculations, and benchmark against an exactly soluble model of interacting bosons in one spatial dimension. As this algorithm retains the fundamental polynomial scaling of quantum Monte Carlo when applied to sign-problem-free models, future applications should allow for the study of entanglement entropy in large scale many-body systems of interacting bosons.

description: BACKGROUND: MYC is a heterogeneously expressed transcription factor that plays a multifunctional role in many biological processes such as cell proliferation and differentiation. It is also associated with many types of cancer including the malignant lymphomas. There are two types of aggressive B-cell lymphoma, namely Burkitt lymphoma (BL) and a subgroup of diffuse large cell lymphoma (DLBCL), which both carry MYC translocations and overexpress MYC but both differ significantly in their clinical outcome. In DLBCL, MYC translocations are associated with an aggressive behavior and poor outcome, whereas MYC-positive BL show a superior outcome. METHODS: To shed light on this phenomenon, we investigated the different modes of actions of MYC in aggressive B-cell lymphoma cell lines subdivided into three groups: (i) MYC-positive BL, (ii) DLBCL with MYC translocation (DLBCLpos) and (iii) DLBCL without MYC translocation (DLBCLneg) for control. In order to identify genome-wide MYC-DNA binding sites a chromatin immunoprecipitation followed by high-throughput sequencing (ChIP-Seq) was performed. In addition, ChIP-Seq for H3K4me3 was used for determination of genomic regions accessible for transcriptional activity. These data were supplemented with gene expression data derived from RNA-Seq. RESULTS: Bioinformatics integration of all data sets revealed different MYC-binding patterns and transcriptional profiles in MYC-positive BL and DLBCL cell lines indicating different functional roles of MYC for gene regulation in aggressive B-cell lymphomas. Based on this multi-omics analysis we identified ADGRE5 (alias CD97) - a member of the EGF-TM7 subfamily of adhesion G protein-coupled receptors - as a MYC target gene, which is specifically expressed in BL but not in DLBCL regardless of MYC translocation. CONCLUSION: Our study describes a diverse genome-wide MYC-DNA binding pattern in BL and DLBCL cell lines with and without MYC translocations. Furthermore, we identified ADREG5 as a MYC target gene able to discriminate between BL and DLBCL irrespectively of the presence of MYC breaks in DLBCL. Since ADGRE5 plays an important role in tumor cell formation, metastasis and invasion, it might also be instrumental to better understand the different pathobiology of BL and DLBCL and help to explain discrepant clinical characteristics of BL and DLBCL.

Our results are obtained from a numerical investigation of the time domain profiles of the perturbations.

Publisher: name: Universität der Künste Berlin

description: Handy Handbook of Hands is about the finger binary systems. The first part of this book shows how to count and display binary numbers on the fingers. In the second part, a binary finger alphabet is developed that enables the communication of words with fingers. Children learn to count with their fingers at an early age. The Latin word for fingers or toes “digitus” is the root of the English word digit. A normal person has, if nothing unforeseen happens, five digits on each hand. This limits the counting of the fingers to ten. By using binary numbers with the fingers of one or both hands, it is possible to count and display all numbers from 0 to 1023. Counting in binary is one thing, but fingers can switch from “counting mode” to “text mode”. The binary finger alphabet technique allows communicating words and even entire sentences with the fingers. It is similar to Morse code and gives each letter of the alphabet a specific finger constellation. It is structured from simple finger constellations for the most commonly used letters of the English alphabet to more difficult constellations for rare letters.
title: Living with a genetic form of arrhythmogenic right ventricular cardiomyopathy causing sudden cardiac death: symptoms of depression, anxiety and post-traumatic stress in transmembrane protein 43 p.S358L mutation positive family members with an ICD

description: Arrhythmogenic right ventricular cardiomyopathy (ARVC) caused by a p.S358L mutation in TMEM43 has a high incidence in Newfoundland and Labrador (NL), with sudden cardiac death (SCD) often the first symptom. Implantable cardioverter defibrillators (ICDs) are effective at preventing SCD. Mental health effects have not been studied in this population. This study sought to identify symptoms of depression, anxiety, and posttraumatic stress in those with TMEM43 p.S358L ARVC and an ICD. TMEM43 p.S358L positive individuals with an ICD were recruited. Participants completed the Patient Health Questionnaire-9 (PHQ-9), Zung self-rating anxiety scale (SAS), and the posttraumatic checklist-civilian version (PCL-C). Prevalences of depression, anxiety and posttraumatic stress symptoms were described and compared with scores in unaffected family members and general population norms. Fifty-three ICD patients completed the questionnaires. Univariate linear analysis revealed that the three scales were significantly positively related to each other (Pearson’s r > 0.6). Anxiety was related to number of appropriate ICD discharges (B=0.355, p=0.022) and the PCL-C scale was significantly related to age (B=-.322, p=0.019). Multivariate regression models predicting each scale score revealed that only the three scales contributed to the variance, excepting age, which remained significant in the model predicting posttraumatic stress scale scores (B=-.215, p=0.015). A significant percentage of participants scored above the clinical cutoff levels for depression (28.3%), anxiety (49%) and posttraumatic stress (32%). Scoring high on one mental health scale (PHQ-9, SAS, or PCL-C) was strongly associated with scoring high on the subsequent scales. Findings can inform the provision of mental health services to these patients.
This Girl Can: An Ecological Approach to Investigating Physical Activity in Urban Females
Creators: name: Hull, Reisha Edith Matilda
Publisher: name: London South Bank University
Year: 2019

description: Despite the widely documented physical, psychological and social benefits associated with physical activity, 86% of young females in the UK are insufficiently active (Sport England 2018). In order to improve physical activity levels among young females aged 14-25 in the London Borough of Lambeth, the local council partnered with five physical activity providers and our research team. Together we embarked on the This Girl Can Lambeth project which was inspired by the national campaign This Girl Can. Our role in the project was to evaluate its implementation and outcomes, and additionally to identify barriers and facilitators to participation for this population. We wanted to capture the intrapersonal and interpersonal factors that are often described in literature, but also the relevant environmental, organisational and legislative factors, therefore we used an ecological framework to guide our research. A systematic review of literature showed that the majority of interventions aimed at young females take place in educational settings and focus on either physiological or psychological intrapersonal factors. In an intervention study we compared a physical education program with a school-based intervention program, to investigate its effects on the behaviour and health of young females. Although the intervention program included multi-sports, and encouraged the building of rapport and a foundation for sustained participation in community-based exit routes, we found no clear benefit of the intervention program over physical education. In subsequent qualitative studies we investigated what was amiss. We conducted focus groups with young females who had participated in the intervention programs to understand what factors they perceived to influence their participation. The focus groups highlighted organisational and environmental factors as primary barriers to physical activity. Such factors are stable features of their lives making them difficult barriers to overcome. However, when we interviewed the physical activity providers, the barriers to participation that they perceived were quite different. They identified intrapersonal factors such as self-efficacy and body image as the main barriers to participation. The physical activity providers also discussed the influence of organisational, environmental and legislative factors. The findings from this project can inform interventions, research and policy to ensure Girls indeed Can.

title: Factors associated with glycemic control, hospitalization, and mortality among Newfoundland and Labrador residents with diabetes mellitus
Creators: name: Buote, Richard
Publisher: name: Memorial University of Newfoundland
Year: 2022

description: Diabetes is among the most prevalent chronic conditions in Canada. It is characterized by a body's inability to produce or efficiently use insulin. Diabetes can be effectively managed, often with the support of a primary care provider. Unfortunately, the high turnover rate of family physicians (FPs) in Newfoundland and Labrador (NL) threatens continuity of care, potentially contributing to poorer health outcomes for people with diabetes. This study examines the relationship between FP turnover and glycemic control, hospitalization, and mortality among patients with diabetes in NL. It was hypothesized that FP turnover would be related to the three outcomes of interest. Specifically, it was expected that high turnover rates would be associated with poorer glycemic control and increased risk of hospitalization and mortality. To examine these hypotheses, a cross-sectional analysis of adults (20+ years) with diabetes in NL between 2011 and 2015 was performed. Secondary data sources were linked, including the provincial Chronic Disease Registry and the Physician and Medical Practice Database. Multivariate binary logistic regression was used to examine the relationship between FP turnover, glycemic control, hospitalization, and mortality while controlling for important covariates. The analyses provided mixed support for the hypotheses. FP turnover was found to be associated with glycemic control and hospitalization but not mortality. Further, FP turnover was associated with an increased risk of hospitalization, but the direction of the relationship between turnover and glycemic control was inconsistent with the hypothesis. Findings from this study also suggest that regions with no FPs performed similarly to regions with low turnover on the outcomes of glycemic control and hospitalization. These findings may have implications for the delivery of primary care in NL. Future studies should examine primary care models in regions with no FPs and consider whether these models could be more widely applied in NL for chronic disease management. Additionally, studies in other provinces should compare regions with high rates of primary care change (i.e., high turnover) to regions with consistent primary care availability to determine whether consistent primary care delivery, irrespective of the presence of FPs, is associated with better outcomes for patients with chronic condition.

description: Abstract This article undertakes an investigation of the Brazilian sociological tradition in the 1930s and its relationship with conservative modernization. On the basis of a wide range of concepts that have been employed by modernist sociologists, it is possible to obtain a clear view of the tension that existed between the world of culture and the political sphere. Modernist sociology strikes a distinctive note in putting into effect concepts such as patriarchalism, familism, patrimonialism, personalism, agnatism, clientelism and a myriad of obstacles caused by the privatism that was contained in their thinking. This means it can play a decisive role in constituting the public life of its society in the way that its State is organized and the history of its society is narrated.

description: We calculate the electromagnetic pion form factor in lattice QCD with 2+1 flavors of the dynamical overlap quarks. Up and down quark masses are set below their physical values so that the system is in the so-called epsilon regime with the small size of our lattice ~ 1.8 fm. The finite volume corrections are generally expected to be ~ 100% in the epsilon regime. We, however, find a way to automatically cancel the dominant part of them. Inserting non-zero momenta and taking appropriate ratios of the two and three point functions, we can eliminate the contribution from the zero-momentum pion mode. Then the remaining finite volume effect is a small perturbation from the non-zero modes. Our lattice data agree with this theoretical prediction and the extracted pion charge radius is consistent with the experiment.

description: Repeating patterns of spike sequences from a neuronal network have been proposed to be useful in the reconstruction of the network topology. Reverberations in a physiologically realistic model with various physical connection topologies (from random to scale-free) have been simulated to study the effectiveness of the pattern-matching method in the reconstruction of network topology from network dynamics. Simulation results show that functional networks reconstructed from repeating spike patterns can be quite different from the original physical networks; even global properties, such as the degree distribution, cannot always be recovered. However, the pattern-matching method can be effective in identifying hubs in the network. Since the form of reverberations are quite different for networks with and without hubs, the form of reverberations together with the reconstruction by repeating spike patterns might provide a reliable method to detect hubs in neuronal cultures.

description: We show how to avoid unnecessary and uncontrolled assumptions usually made in the literature about soft SU(3) flavor symmetry breaking in determining the two-flavor nucleon matrix elements relevant for direct detection of WIMPs. Based on SU(2) Chiral Perturbation Theory, we provide expressions for the proton and neutron scalar couplings $f_u^{p,n}$ and $f_d^{p,n}$ with the pion-nucleon sigma-term as the only free parameter, which should be used in the analysis of direct detection experiments. This approach for the first time allows for an accurate assessment of hadronic uncertainties in spin-independent WIMP-nucleon scattering and for a reliable calculation of isospin-violating effects. We find that the traditional determinations of $f_u^p-f_u^n$ and $f_d^p-f_d^n$ are off by a factor of 2.

This provides complete simplicial fan realizations of simplicial multi-associahedra $Δ_{2k+4,k}$, whose facets are in correspondence with $k$-triangulations of a convex $(2k+4)$-gon. This solves the first open case of the problem of finding fan realizations where polytopality is not known. The techniques presented in this paper work for all finite Coxeter groups and we hope that they will be useful to construct fans realizing subword complexes in general. In particular, we present fan realizations of two previously unknown cases of subword complexes of type $A_4$, namely the multi-associahedra $Δ_{9,2}$ and $Δ_{11,3}$.

description: This article reports on the development and experimental results of commercial plasma display panels adapted for their potential use as micropattern gas radiation detectors. The plasma panel sensors (PPS) design an materials include glass substrates, metal electrodes and inert gas mixtures which provide a physically robust, hermetically-sealed device. Plasma display panels used as detectors were tested with cosmic ray muons, beta rays and gamma rays, protons and thermal neutrons. The results demonstrated rise times and time resolution of a few nanoseconds, as well as sub-millimeter spatial resolution compatible with the pixel pitch.

Concrete particle characterization using impedance cytometry
Creators: name: Vasudevamurthy, Kavya
Publisher: name: No Publisher Supplied
Year: 2018

description: We demonstrate a novel method to detect and characterize the size and number of Wollastonite particles using microfluidic impedance cytometry. The fabricated device which consists of gold electrodes micro-fabricated in a microchannel is capable of detecting particles >1 micron. Particle characterization is often carried out across a wide range of industries and is a critical parameter in the manufacture of various products to help improve the characteristics, performance or quality of powders or particles. There are a number of commercially available particle characterization techniques like laser diffraction, dynamic light scattering, electrophoretic light scattering, automated imaging, sedimentation etc that can be used to measure particulate samples and each has its relative strengths and limitations-there is no universally applicable technique for all samples. Our approach uses electrical impedance spectroscopy which measures the change in impedance as the particles in suspension pass through the sensor. It is a highly precise, low cost alternative for particle size characterization with a smaller footprint offering quick analysis time and is suitable for relatively broad range of particle sizes.
Mechanical Behaviour of Rocks with Veins and Joints under Confinement and Strain Rate

description: Veins are mineral-filled structures within rocks that can decrease rock strength and shift failure modes from tensile to shear. This thesis analyses the mechanical behaviour and fracture process of veined rocks under various loading conditions to investigate the vein distribution effect by integrating experimental results with numerical models. Then this study focuses on shear failure under different strain rate, assessing the cumulative damage and weakening of rock specimens. Finally, it compares the reinforcement on bolted specimens under various shear loading. These findings contribute to enhancing the stability of rock structures and developing safer geotechnical applications.

description: We present the results of a new search for bright star-forming galaxies at z ~ 7 within the UltraVISTA DR2 and UKIDSS UDS DR10 data, which together provide 1.65 sq deg of near-infrared imaging with overlapping optical and Spitzer data. Using a full photo-z analysis to identify high-z galaxies and reject contaminants, we have selected a sample of 34 luminous (-22.7 < M_UV < -21.2) galaxies with 6.5 < z < 7.5. Crucially, the deeper imaging provided by UltraVISTA DR2 confirms all of the robust objects previously uncovered by Bowler et al. (2012), validating our selection technique. Our sample includes the most massive galaxies known at z ~ 7, with M_* ~ 10^{10} M_sun, and the majority are resolved, consistent with larger sizes (r_{1/2} ~ 1 - 1.5 kpc) than displayed by less massive galaxies. From our final sample, we determine the form of the bright end of the rest-frame UV galaxy luminosity function (LF) at z ~ 7, providing strong evidence that the bright end of the z = 7 LF does not decline as steeply as predicted by the Schechter function fitted to fainter data. We consider carefully, and exclude the possibility that this is due to either gravitational lensing, or significant contamination of our galaxy sample by AGN. Rather, our results favour a double power-law form for the galaxy LF at high z, or, more interestingly, a LF which simply follows the form of the dark-matter halo mass function at bright magnitudes. This suggests that the physical mechanism which inhibits star-formation activity in massive galaxies (i.e. AGN feedback or some other form of `mass quenching') has yet to impact on the observable galaxy LF at z ~ 7, a conclusion supported by the estimated masses of our brightest galaxies which have only just reached a mass comparable to the critical `quenching mass' of M_* = 10 ^{10.2} M_sun derived from studies of the mass function of star-forming galaxies at lower z.

description: Numerous applications in scheduling, such as resource allocation or steel manufacturing, can be modeled using the NP-hard Independent Set problem (given an undirected graph and an integer k, find a set of at least k pairwise non-adjacent vertices). Here, one encounters special graph classes like 2-union graphs (edge-wise unions of two interval graphs) and strip graphs (edge-wise unions of an interval graph and a cluster graph), on which Independent Set remains NP-hard but admits constant-ratio approximations in polynomial time. We study the parameterized complexity of Independent Set on 2-union graphs and on subclasses like strip graphs. Our investigations significantly benefit from a new structural "compactness" parameter of interval graphs and novel problem formulations using vertex-colored interval graphs. Our main contributions are: 1. We show a complexity dichotomy: restricted to graph classes closed under induced subgraphs and disjoint unions, Independent Set is polynomial-time solvable if both input interval graphs are cluster graphs, and is NP-hard otherwise. 2. We chart the possibilities and limits of effective polynomial-time preprocessing (also known as kernelization). 3. We extend Halldórsson and Karlsson (2006)'s fixed-parameter algorithm for Independent Set on strip graphs parameterized by the structural parameter "maximum number of live jobs" to show that the problem (also known as Job Interval Selection) is fixed-parameter tractable with respect to the parameter k and generalize their algorithm from strip graphs to 2-union graphs. Preliminary experiments with random data indicate that Job Interval Selection with up to fifteen jobs and 5*10^5 intervals can be solved optimally in less than five minutes.

description: In this article, we discuss the propagation of scalar fields in conformally transformed spacetimes with either minimal or conformal coupling. The conformally coupled equation of motion is transformed into a one-dimensional Schrödinger-like equation with an invariant potential under conformal transformation. In a second stage, we argue that calculations based on conformal coupling yield the same Hawking temperature as those based on minimal coupling. Finally, it is conjectured that the quasi normal modes of black holes are invariant under conformal transformation.

description: Provided the consistency relations are not violated, the recent Bicep2 observations pin down the absolute normalization, the spectral slope and the maximal frequency of the cosmic graviton background produced during inflation. The properly normalized spectra are hereby computed from the lowest frequencies (of the order of the present Hubble rate) up to the highest frequency range in the GHz region. Deviations from the conventional paradigm cannot be excluded and are examined by allowing for different physical possibilities including, in particular, a running of the tensor spectral index, an explicit breaking of the consistency relations and a spike in the high-frequency tail of the spectrum coming either from a post-inflationary phase dominated by a stiff fluid of from the contribution of waterfall fields in a hybrid inflationary context. The direct determinations of the tensor to scalar ratio at low frequencies, if confirmed by the forthcoming observations, will also affect and constrain the high-frequencies uncertainties. The limits on the cosmic graviton backgrounds coming from wide-band interferometers (such as Ligo/Virgo, Lisa and Bbo/Decigo) together with a more accurate scrutiny of the tensor B mode polarization at low frequencies will set direct bounds on the post-inflationary evolution and on other unconventional completions of the standard lore.
