description: The Higgs field of the pure Standard Model can lead to the inflationary expansion of the early Universe if it is non-minimally coupled to gravity. The model predicts Cosmic Microwave Background (CMB) parameters in perfect agreement with the current observations and has implications for the Higgs boson mass. We review the model, its predictions, problems arising with its quantization and some closely related models.

description: This article is concerned with Monte-Carlo methods for the estimation of the trace of an implicitly given matrix $A$ whose information is only available through matrix-vector products. Such a method approximates the trace by an average of $N$ expressions of the form $\ww^t (A\ww)$, with random vectors $\ww$ drawn from an appropriate distribution. We prove, discuss and experiment with bounds on the number of realizations $N$ required in order to guarantee a probabilistic bound on the relative error of the trace estimation upon employing Rademacher (Hutchinson), Gaussian and uniform unit vector (with and without replacement) probability distributions. In total, one necessary bound and six sufficient bounds are proved, improving upon and extending similar estimates obtained in the seminal work of Avron and Toledo (2011) in several dimensions. We first improve their bound on $N$ for the Hutchinson method, dropping a term that relates to $rank(A)$ and making the bound comparable with that for the Gaussian estimator. We further prove new sufficient bounds for the Hutchinson, Gaussian and the unit vector estimators, as well as a necessary bound for the Gaussian estimator, which depend more specifically on properties of the matrix $A$. As such they may suggest for what type of matrices one distribution or another provides a particularly effective or relatively ineffective stochastic estimation method.

description: The expeditious growth of Africa's population, as well as the opportunities and challenges this poses in terms of education and training of the African youth have pointed to ever -growing interdependencies between the pivotal role of information and communication technology (ICT) and harnessing the potential of the internet. The mutual entanglement of both spheres manifests on many levels with digital governance being a vital enabler. The recent rise of big data and computational techniques have brought about new opportunities for participation, organizing and collective action by citizens. If the 20th century engineers of consent had magnifying glasses and baseball bats, those of the 21st century have acquired telescopes, microscopes and scalpels in the shape of digital technologies and analytics1. These new technologies hold incredible promise for human welfare. They offer us powerful new ways to achieve our shared commitments to each and every one of the Sustainable Development Goals (SDGs), a set of 17 socioeconomic, political and environmental objectives forming and structuring the development agenda of the next 10 years2. Against this background, a question one may ask is: what role can the internet ecosystem community play to make this world a better place? Can digital technologies of the big data era, and the opportunities, risks and questions they raise, be leveraged as forces of positive disruption?3
 This paper outlines approaches for greater transparency and improved governance of the internet to promote inclusivity and development using learnings from the modules. It makes a case that governance of internet (and by algorithms) goes beyond regulating the design and implementation of code and the technology itself and involves a wider evidence-based approach relying on risk and impact assessments, organizational approaches, and business models and strategies. The paper also focuses on the governing effects of internet algorithms in information societies.

description: We present an extended version of the dynamical model for a multi-quark droplet evolution described in our proceeding paper. The model includes collective expansion of the droplet, effects of the vacuum pressure and surface tension, and now a non-zero baryon number. The hadron emission from the droplet is described following Weisskopf's statistical model. We consider evolutions of droplets with different initial temperatures and net baryon number. It is found that the introduction of a non-zero net baryon number does not change the lifetime of the droplets significantly. Only when we consider an initially very baryon-rich, low-temperature droplets is the lifetime is decreased significantly. We have, furthermore, found a convergence of both baryon chemical potential and temperature toward the values $μ_{\rm B} \approx$ 450 MeV and $T \approx 150$ MeV. This convergence is linked to the competing emission of baryons versus mesons.

description: The magnetohydrodynamics (MHD) is modified to incorporate the parity violation in the Standard Model leading to a new instability of magnetic fields in the electroweak plasma in the presence of nonzero neutrino asymmetries. The main ingredient for such a modified MHD is the antisymmetric part of the photon polarization tensor in plasma, where the parity violating neutrino interaction with charged leptons is present. We calculate this contribution to the polarization tensor connected with the Chern-Simons term in effective Lagrangian of the electromagnetic field. The general expression for such a contribution which depends on the temperature and the chemical potential of plasma as well as on the photon's momentum is derived. The instability of a magnetic field driven by the electron neutrino asymmetry for the $ν$-burst during the first second of a supernova explosion can amplify a seed magnetic field of a protostar, and, perhaps, can explain the generation of strongest magnetic fields in magnetars. The growth of a cosmological magnetic field driven by the neutrino asymmetry density $Δn_ν=n_ν - n_{\barν}\neq 0$ is provided by a lower bound on $|ξ_{ν_e}|=|μ_{ν_e}|/T$ which is consistent with the well-known Big Bang nucleosynthesis (upper) bound on neutrino asymmetries in a hot universe plasma.

description: Massive young star clusters are fundamental building blocks of galaxies, and the most abundant reservoirs of newly born stars in the Milky Way. A robust membership assignment is fundamental to study their populations and physical properties. Traditionally, various methods have been used to separate members from the field stars, including the presence of X-ray emission, infrared excess, spectroscopic youth features, and, to a lesser extent, proper motions. With the advent of the Gaia mission and its precision astrometry, we are now able to study complete stellar populations in massive young clusters at kpc distances, over areas much larger than ever before. In this contribution, I will present an application of the Probabilistic Random Forest algorithm to study the stellar population in the Rosette Nebula, harbouring a young (~2 Myr) cluster NGC 2244 located at a distance of ~1.5 kpc. Our new sample of candidate members doubles the previously identified one, allowing us to derive the most complete Initial Mass Function extending down to 0.1-0.2 MSun, study the spatial structure of the region, detect expansion of NGC 2244, and discuss potential scenarios for its formation.

title: Characterisation of tropomyosin heterodimers carrying single cardiomyopathy mutations
Creators: name: Janco, Miroslav
Publisher: name: University of Kent
Year: 2023

description: It is known that different point mutations in α-tropomyosin (Tm) can cause either hypertrophic (HCM) or dilated (DCM) cardiomyopathy. Both of these serious pathologies have a distinct phenotype with unknown mechanisms of development. Biochemical in vitro studies provide valuable information for exploring downstream consequences of cardiomyopathy mutations in sarcomeric proteins leading to cardiac remodelling and consequent heart failure. Tm is a linear a-helical coil-coiled dimer involved in calcium dependent regulation of muscle contraction. Prior to this work, the effects of mutations in Tm on regulation of muscle contraction have been made exclusively with Tm mutant homodimers. However, individuals with a heterozygous background may express mutant and WT proteins in a 1 : 1 ratio which can assembly into a mixture of αα, αα* and α*α* Tm dimers. We found that presence of mutation has little effect on dimer formation between the mutant and the WT monomers, therefore theoretical ratio of the Tm dimers in vivo may be 1 : 2 : 1, respectively. This assumption would make the heterodimer predominant. The properties of in vitro assembled Tm heterodimers carrying HCM (WT-D175N and WT-E180G) and DCM (WT-E40K, WT-E54K, and WT-D230N) causing mutations were examined including thermal stability, flexibility, actin affinity, calcium regulation of 51 biding, and calcium regulation of myofibril force. We showed that various properties of the heterodimers can be similar to those of the wild-type (thermal stability of reduced WTD175N; actin affinity of WT-E40K, and WT-D175N; ΔpCa of WT-E40K, WT-E54K, WT-E180G, WT-D230N), similar of those to the mutant homodimer (ΔpCa of WT-D175N, flexibility of WT-D175N and WT-E180G), intermediate between the two (actin affinity of WT-E180G), or different from both (thermal stability of reduced WT-E40K, WT-E54K, WT-E180G, and WTD230N; actin affinity ofWT-E40, WT-E54K, and WT-D230N; ΔpCa of D175N). The results demonstrate that the properties of Tm heterodimers cannot be predicted from the interpolation of the WT and mutant homodimer data. The distinct properties of heterodimers establish that it will be important to define if the pathogenic agent is a homodimer, a heterodimer or both for each known cardiomyopathy mutation in Tm.
Approximating Markov chains and V-geometric ergodicity via weak perturbation theory

description: Let $P$ be a Markov kernel on a measurable space $\X$ and let $V:\X\r[1,+\infty)$. This paper provides explicit connections between the $V$-geometric ergodicity of $P$ and that of finite-rank nonnegative sub-Markov kernels $\Pc_k$ approximating $P$. A special attention is paid to obtain an efficient way to specify the convergence rate for $P$ from that of $\Pc_k$ and conversely. Furthermore, explicit bounds are obtained for the total variation distance between the $P$-invariant probability measure and the $\Pc_k$-invariant positive measure. The proofs are based on the Keller-Liverani perturbation theorem which requires an accurate control of the essential spectral radius of $P$ on usual weighted supremum spaces. Such computable bounds are derived in terms of standard drift conditions. Our spectral procedure to estimate both the convergence rate and the invariant probability measure of $P$ is applied to truncation of discrete Markov kernels on $\X:=\N$.

description: Abstract

Wheat productivity is often constrained by suboptimal sowing times and inappropriate cultivar selection, leading to reduced yields under varying environmental conditions. Identifying the best sowing dates and suitable cultivars can enhance growth performance and yield outcomes. A field experiment was conducted at the Agronomic Research Area, University of Agriculture, Faisalabad, to evaluate the effects of four sowing dates (November 5ᵗʰ, November 20ᵗʰ, December 5ᵗʰ, and December 20ᵗʰ) and four wheat cultivars (Arooj-22, Subhani-21, Nawab-21, and Sadiq-21) on wheat growth and yield. The experiment followed a Randomized Complete Block Design (RCBD) with split arrangements and three replications. Results indicated that early sowing, particularly on November 20ᵗʰ, led to the highest grain yield (4932.25 kg ha⁻¹) and a maximum number of productive tillers (373 m²). Among cultivars, Arooj-22 and Subhani-21 exhibited superior performance, with Arooj-22 yielding 4574.26 kg ha⁻¹ and Subhani-21 achieving the highest Leaf Area Index (4.05). The DSSAT model was calibrated and evaluated using the field data, showing strong agreement between observed and simulated values. Model calibration produced low root mean square error (RMSE) values for key parameters, including days to anthesis (RMSE = 1-2), LAI (RMSE = 0.4-0.7), and grain yield (RMSE = 2-85). Model evaluation across different treatments yielded RMSE values of 314.14 to 673.18 for grain yield and 0.22 to 1.89 for LAI, indicating acceptable prediction accuracy. The rise in temperature significantly impacts wheat yield, with varying effects across different varieties. Arooj-22 saw a 1.20% yield decrease at 2.5°C, rising to 26.28% at 4.5°C. Subhani-21's yield dropped by 8.32% at 2.5°C and 30.86% at 4.5°C. Nawab-21 was the most affected, with a 16.33% yield reduction at 2.5°C and 38.84% at 4.5°C, while Sadiq-21 and Arooj-22 showed greater resilience. These results highlight the importance of optimal sowing time and cultivar selection, as well as the reliability of the DSSAT model for simulating wheat growth under varying environmental conditions.
Leptogenesis with Lepton-Number-Violating Dirac Neutrinos

description: Dirac neutrinos with lepton-number-violating interactions can give rise to a new leptogenesis mechanism. In its simplest renormalizable realization, based on a gauged B-L symmetry spontaneously broken by four units, the decay of a new scalar creates an asymmetry in the right-handed neutrinos. A neutrinophilic two-Higgs-doublet model converts this asymmetry to the baryons, provides a natural explanation of the small neutrino masses, and can lead to an effective number of relativistic degrees of freedom of N(eff) = 3.29 due to the entropy-suppressed contribution of the right-handed neutrinos.

Environmental Justice

description: With the ever-increasing socioeconomic inequalities, and environmental, some have started to argue that there is a correlation between environmental rights, environmental law, and jurisprudence, and how the various governments have become increasingly involved in resolving dilemmas affecting environmental justice. Issues of aligning governments to meet the challenges of sustainable
 development have been ranked among the top emerging quagmires of the 21st century. However, the concept of environmental justice arose as another key theme in the 21st century; that involves policy issues not recognized, in general, environmental ideologies, which concern strict ecology matters. Using case studies, the paper argues that current environmental injustices have roots in colonial laws and systemic racism perpetrated over the past years.

description: Neutron production and transport in spallation targets made of uranium and americium are studied with a Geant4-based code MCADS (Monte Carlo model for Accelerator Driven Systems). A good agreement of MCADS results with experimental data on neutron- and proton-induced reactions on $^{241}$Am and $^{243}$Am nuclei allows to use this model for simulations with extended Am targets. It was demonstrated that MCADS model can be used for calculating the values of critical mass for $^{233,235}$U, $^{237}$Np, $^{239}$Pu and $^{241}$Am. Several geometry options and material compositions (U, U+Am, Am, Am$_2$O$_3$) are considered for spallation targets to be used in Accelerator Driven Systems. All considered options operate as deep subcritical targets having neutron multiplication factor of $k \sim 0.5$. It is found that more than 4 kg of Am can be burned in one spallation target during the first year of operation.

description: Dark matter N-body simulations suggest that the velocity distribution of dark matter is anisotropic. In this work we employ a mass model for the Milky Way whose parameters are determined from a fit to kinematical data. Then we adopt an ansatz for the dark matter phase space distribution which allows to construct self-consistent halo models which feature a degree of anisotropy as a function of the radius such as suggested by the simulations. The resulting velocity distributions are then used for an analysis of current data from dark matter direct detection experiments. We find that velocity distributions which are radially biased at large galactocentric distances (up to the virial radius) lead to an increased high velocity tail of the local dark matter distribution. This affects the interpretation of data from direct detection experiments, especially for dark matter masses around 10 GeV, since in this region the high velocity tail is sampled. We find that the allowed regions in the dark matter mass-cross section plane as indicated by possible hints for a dark matter signal reported by several experiments as well as conflicting exclusion limits from other experiments shift in a similar way when the halo model is varied. Hence, it is not possible to improve the consistency of the data by referring to anisotropic halo models of the type considered in this work.

description: We present measurements of the cross sections for the two main production modes of single top quarks in $p\bar{p}$ collisions at $\sqrt{s} = 1.96$ TeV in the Run II data collected with the D0 detector at the Fermilab Tevatron Collider, corresponding to an integrated luminosity of 9.7 fb$^{-1}$. The s-channel cross section is measured to be $σ(p\bar{p} \to tb+X) = 1.10^{+0.33}_{-0.31}$ pb with no assumptions on the value of the t-channel cross section. Similarly, the t-channel cross section is measured to be $σ(p\bar{p} \to tqb+X) = 3.07^{+0.54}_{-0.49}$ pb. We also measure the $s+t$ combined cross section as $σ(p\bar{p} \to tb+X, tqb+X) = 4.11^{+0.60}_{-0.55}$ pb and set a lower limit on the CKM matrix element $|V_{tb}| > 0.92$ at $95\%$ C.L., assuming $m_t=172.5$ GeV. The probability to measure a cross section for the s channel at the observed value or higher in the absence of signal is $1.0\times 10^{-4}$, corresponding to a significance of 3.7 standard deviations.

description: Reclassifying LiDAR Points by selecting a specified elevation range involves filtering and reorganizing LiDAR data based on their elevation values. This process allows users to select points within a defined elevation range or to exclude unwanted points, such as noise or outliers that don't meet the desired criteria.

 

Once filtered, the selected points are reclassified into different ASPRS categories, grouping them by elevation. For instance, points can be categorized into ranges that represent terrain features like ground, water, low vegetation, high vegetation, or other relevant landscape elements. This improves data accuracy and clarity for further analysis.

description: We study the interplay between Dirac and Schrödinger fermions in the polarization properties of a two-dimensional electron gas (2DEG). Specifically, we analyze the low-energy sector of narrow-gap semiconductors described by a two-band Kane model. In the context of quantum spin Hall insulators, particularly, in Hg(Cd)Te quantum wells, this model is named Bernevig-Hughes-Zhang model. Interestingly, it describes electrons with intermediate properties between Dirac and Schrödinger fermions. We calculate the dynamical dielectric function of such a model at zero temperature within random phase approximation. Surprisingly, plasmon resonances are found in the intrinsic (undoped) limit, whereas they are absent - in that limit - in graphene as well as ordinary 2DEGs. Additionally, we demonstrate that the optical conductivity offers a quantitative way to identify the topological phase of Hg(Cd)Te quantum wells from a bulk measurement.

description: The Palestinian-Israeli problem has been the most significant obstacle in the peace process in the Middle East. The Balfour Declaration between the British Empire and the Zionists in 1917, which explicitly declared support for creating a "national home for the Jewish people" at the expense of the Palestinians, began after the Jewish exodus to Palestine after WW1. There have been three wars between Arab-Israel and Zionist imperial control over the Palestinians, resulting in the displacement of millions of refugees and hundreds of thousands of deaths of the Palestinians. Since the 1948 war, there have been no official ArabIsraeli relations except for Egypt and Jordan. However, geopolitical changes over the last decade have completely disrupted the Middle East and North Africa's conventional political order thanks to the Arab Spring, the emergence of the Muslim Brotherhood and ISIS, and new non-Arab hegemonial forces like Iran and Turkey. Over the last decade, these developments have altered the perspective of the Arab monarchies towards the Palestinian issue, which they conceive as a mere distraction from real immediate threats. It finally contributed to Abraham's agreement between the United Arab Emirates and Israel and then the agreement between Bahrain and Israel. While there is the considerable fuss about the agreement, it will only lead to more conflict and chaos in the MENA region from a pragmatic point of view, as has emerged in the recent developments in Libya and the Mediterranean Sea.

description: The AdS/CFT correspondence predicts that background non-abelian magnetic fields induce instabilities in strongly-coupled systems with non-abelian global symmetries. These instabilities lead to the formation of vortex lattices in which the non-abelian currents "antiscreen" the applied magnetic field. From the bulk perspective, this behaviour can be traced to a well-known instability of Yang-Mills theory. We analyse the phase structure of the instability and comment on aspects of the vortex lattice.

description: We discuss an extension of the standard model by fields not charged under standard model gauge symmetry in which the electroweak symmetry breaking is driven by the Higgs quartic coupling itself without the need for a negative mass term in the potential. This is achieved by a scalar field S with a large coupling to the Higgs field at the electroweak scale which is driven to very small values at high energies by the gauge coupling of a hidden symmetry under which S is charged. This model can remain perturbative all the way to the Planck scale. The Higgs boson is fully SM-like in its couplings to fermions and gauge bosons. However, the effective cubic and quartic self-couplings of the Higgs boson are significantly enhanced.

The top induced backgrounds to Higgs production in the WW -> llvv decay channel at NLO in QCD

description: We present the complete NLO contributions to the pp -> e^+ v_e mu^- vbar_m b bbar + X process in the four flavour scheme, i.e. with massive b quarks, and its contribution to the H -> WW -> llvv measurement in the 1-jet bin at the LHC. This background process includes top pair, single top and non-top quark-resonant contributions. The uncertainty at NLO from renormalisation and factorisation scale dependence is about +30% -20%. We show that the NLO corrections are relatively small, and that separating this background in top pair, Wt and b-quark associated llvv is a fair approximation.

title: Developing and testing a prototype net zero community in the UK

Publisher: name: University of Kent

description: Net-zero energy and net-zero carbon are terms that have gained popularity over the past two decades, to such an extent that their usage is being expanded to the scale of communities and cities. Despite the subject's growing momentum there is ambiguity in its understanding and application. Principles for net-zero have been defined for the building scale and energy systems that analyse and rate sustainability of large-scale developments exist. However, there isn't a set of defined benchmarks for testing the authenticity of net zero in large scale developments. This study aims to develop and test a prototype net zero community in the UK which falls under the temperate climate classification. The focus of the project is to investigate if a sustainable community based on user data from surveys on typical British lifestyles can meet a defined net zero benchmark. This thesis includes three key elements. First, a net zero guide was developed by extrapolating information from current literature and energy rating systems designed to test communities and cities. Second, a prototype community was designed for the temperate climate classification inferred from current and past examples of net zero developments. Third, energy data was gathered for the designed community from an energy modelling software (DesignBuilder) to test if energy demand of the community can be met by renewable energy supply thereby achieving a net zero/positive balance. The community was found to meet net positive energy and net negative carbon emissions. There was an annual 68% surplus energy, of about 535000 kWh/year. The study makes a significant contribution to standardising net zero for easier application of the popularised concept.

description: We show that to correctly describe the effects of the heavy-quark mass, m_h, in DGLAP evolution, it is necessary to work in the so-called `physical' scheme. In this way, we automatically obtain a smooth transition through the heavy-quark thresholds. Moreover, we show that to obtain NLO accuracy, it is sufficient to account for the heavy-quark mass, m_h, just in the LO (one-loop) splitting function. The use of the MS-bar factorisation scheme is not appropriate, since at NLO we deal with a mixture of quarks and gluon (that is, the mass of the heavy parton is not well-defined). The formulae for the explicit m_h dependence of the splitting functions, and for alpha_s, are presented.

description: We revisit a single field inflationary model based on Coleman-Weinberg potentials. We show that in small field Coleman-Weinberg inflation, the observed amplitude of perturbations needs an extremely small quartic coupling of the inflaton, which might be a signature of radiative origin. However, the spectral index obtained in a standard cosmological scenario turns out to be outside the 2 sigma region of the Planck data. When a non-standard cosmological framework is invoked, such as brane-world cosmology in the Randall-Sundrum model, the spectral index can be made consistent with Planck data within 1 sigma, courtesy of the modification in the evolution of the Hubble parameter in such a scheme. We also show that the required inflaton quartic coupling as well as a phenomenologically viable B-L symmetry breaking together with a natural electroweak symmetry breaking can arise dynamically in a generalized B-L extension of the Standard Model where the full potential is assumed to vanish at a high scale.

description: Laser cooled and trapped ions can crystallize and feature discrete solitons, that are nonlinear, topologically-protected configurations of the Coulomb crystal. Such solitons, as their continuum counterparts, can move within the crystal, while their discreteness leads to the existence of a gap-separated, spatially-localized motional mode of oscillation above the spectrum. Suggesting that these unique properties of discrete solitons can be used for generating entanglement between different sites of the crystal, we study a detailed proposal in the context of state-of-the-art experimental techniques. We analyze the interaction of periodically-driven planar ion crystals with optical forces, revealing the effects of micromotion in radio-frequency traps inherent to such structures, as opposed to linear ion chains. The proposed method requires Doppler cooling of the crystal and sideband cooling of the soliton's localized modes alone. Since the gap separation of the latter is nearly independent of the crystal size, this approach could be particularly useful for producing entanglement and studying system-environment interactions in large, two- and possibly three-dimensional systems.
