title: Representing black carbon snow darkening in the JULES land surface model
Creators: name: Johnson, Helen
Publisher: name: University of Reading
Year: 2024

description: Snow darkening contaminants, such as black carbon (BC), can significantly shorten the duration of seasonal snow cover. This can have wide ranging impacts on downstream water availability, and hence on regional hydrology and meteorology. Despite the potential impacts, this
effect is often disregarded in short and seasonal term weather forecasting. This thesis aims
to improve the representation of snow albedo and melt within the Joint UK Land Environment
Simulator, (‘JULES’), a commonly used component of weather and climate simulations across
all timescales, by introducing a means of calculating BC concentration in snow.
Site based tests show that the modified JULES is capable of replicating the observed concentration of BC in snow assuming that accurate BC deposition rates are prescribed and appropriate
values are selected for the top snow layer thickness and the BC scavenging efficiency. At the
test site in Japan, including BC reduced the snow duration by 15 days, bringing the date of final
snow clearance much closer to observations.
Though the results in Japan show substantial benefit from introducing BC to the modelled snow,
globally the results are more mixed. Using a satellite albedo product to verify model performance
across the Northern Hemisphere, it is found that in vegetated areas JULES already underpredicts snow albedo. Consequently, adding BC does not improve albedo prediction in these areas.
Areas without much vegetation however, such as the Canadian Shield region, show considerable improvement when BC is introduced to JULES.
The addition of BC to snow in JULES is shown to impact the surface energy balance and water cycles leading to a shift in evaporation and surface runoff to earlier in the year. This is
especially true in the High Mountain Asia region and has the potential to affect predictions of
drought, flooding and monsoon behaviour, highlighting the importance of accurate snow albedo
prediction. This thesis is © British Crown Copyright, 2025, Met Office.

description: Current state-of-the-art automatic speaker verification (ASV) systems are vulnerable to presentation attacks, and several countermeasures (CMs), which distinguish bona fide trials from spoofing ones, have been explored to protect ASV. However, ASV systems and CMs are generally developed and optimized independently without considering their inter-relationship. In this paper, we propose a new spoofing-aware ASV back-end module that efficiently computes a combined ASV score based on speaker similarity and CM score. In addition to the learnable fusion function of the two scores, the proposed back-end module has two types of attention components, scaled-dot and feed-forward self-attention, so that intra-relationship information of multiple enrollment utterances can also be learned at the same time. Moreover, a new effective trials-sampling strategy is designed for simulating new spoofing-aware verification scenarios introduced in the Spoof-Aware Speaker Verification (SASV) challenge 2022.

description: SAGE is an applied general equilibrium model of the United States economy developed for the analysis of environmental regulations and policies. It is an intertemporal model with perfect foresight, resolved at the sub-national level. Each of the nine regions in the model, representing the nine census divisions, has ve households based on income quintiles. A single government agent levies taxes on labor earnings, capital earnings, production, and consumption. As with many applied general equilibrium models used for the analysis of U.S. environmental and energy policies, the baseline is calibrated to the Energy Information Administration's Annual Energy Outlook. The model is solved as mixed complementarity problem (MCP) using the General Algebraic Modeling System (GAMS).

How increasing parental involvement in the low-cost private schools of Dubai can improve students' English language skills

description: “Literacy arouses hopes, not only in society as a whole but also in the individual who is striving for fulfillment, happiness, and personal benefit by learning how to read and write. Literacy….means far more than learning how to read and write…The aim is to transmit…knowledge and promote social participation”. –UNESCO Institute for Education (cited in Glasgow & Farrell, 2007, p. xiii). I acknowledge that this is an ideal goal, but I believe that it can be achieved by all schools by the use of the right curricula, educational leadership, and promoting a partnership of parents in their child’s schooling. Also, I understand that knowledge is used to mean different things in different parts of the world. In Afghanistan I have noticed it seems to focus more on vocational skills, in Dubai it is more about test-taking skills, and in Canada, based on conversations with my peers who teach at different schools, it differs based on the schools - some have a focus on critical thinking while for others it is being able to achieve high grades. My goal for schools in countries such as Afghanistan and Pakistan, is to understand and accept knowledge as something that benefits the students long-term, which will allow them to be global citizens and schooled so that they can successfully participate in the work force and in their society. For this goal to be achieved, I think it is essential that family literacy be part of schooling. This involves teaching families how to enable effective learning within their child, while at the same time enabling learning of the families, be it in a vocational field or in a language.

description: Two or more catalysts conducting multistep reactions in the same reactor, concurrent tandem catalysis, could enable (bio)pharmaceutical and fine chemical manufacturing to become much more sustainable. Herein we report that co-immobilization of metal nanoparticles and a biocatalytic system within a synthetic covalent organic framework capsule, COFcap-2, functions like an artificial cell in that, whereas the catalysts are trapped within 300-400 nm cavities, substrates/products can ingress/egress through ca. 2 nm windows. The COFcap-2 reactor is first coated onto an electrode surface and then used to prepare eleven homochiral amines using dinitrogen as a feedstock. The amines, including drug product intermediates and active pharmaceutical ingredient, are prepared in >99% enantiomeric excess under ambient conditions in water. Importantly, the COFcap-2 system is recycled 15 times with retention of performance, addressing the relative instability and poor recyclability of enzymes that has hindered their broad implementation for energy efficient, low waste production of chemicals and (bio)pharmaceuticals.

description: The galaxy cluster Abell 1644 ($\bar{z}=0.047$) is known for its remarkable spiral-like X-ray emission. It was previously identified as a bimodal system, comprising the subclusters, A1644S and A1644N, each one centered on a giant elliptical galaxy. In this work, we present a comprehensive study of this system, including new weak-lensing and dynamical data and analysis plus a tailor-made hydrodynamical simulation. The lensing and galaxy density maps showed a structure in the North that could not be seen on the X-ray images. We, therefore, rename the previously known northern halo as A1644N1 and the new one as A1644N2. Our lensing data suggests that those have fairly similar masses: $M_{200}^{\rm N1}=0.90_{-0.85}^{+0.45} \times10^{14}$ and $M_{200}^{\rm N2}=0.76_{-0.75}^{+0.37} \times10^{14}$ M$_\odot$, whereas the southern structure is the main one: $M_{200}^{\rm S}=1.90_{-1.28}^{+0.89}\times 10^{14}$ M$_\odot$. Based on the simulations, fed by the observational data, we propose a scenario where the remarkable X-ray characteristics in the system are the result of a collision between A1644S and A1644N2 that happened $\sim$1.6 Gyr ago. Currently, those systems should be heading to a new encounter, after reaching their maximum separation.

description: The requisite scope of analysis to adequately estimate the social cost of environmental regulations has been subject to much discussion. The literature has demonstrated that engineering or partial equilibrium cost estimates likely underestimate the social cost of large-scale environmental regulations and environmental taxes. However, the conditions under which general equilibrium (GE) analysis adds value to welfare analysis for single-sector technology or performance standards, the predominant policy intervention in practice, remains an open question. Using a numerical computable general equilibrium (CGE) model, we investigate the GE effects of regulations across different sectors, abatement technologies, and regulatory designs. Our results show that even for small regulations the GE effects are significant, and that engineering estimates of compliance costs can substantially underestimate the social cost of single-sector environmental regulations. We find the downward bias from using engineering costs to approximate social costs depends on the input composition of abatement technologies and the regulated sector.

description: Context. 55 Cnc e is a transiting super-Earth orbiting a solar-like star with an orbital period of 17.7 hours. In 2011, using the MOST space telescope, a quasi-sinusoidal modulation in flux was detected with the same period as the planetary orbit. The amplitude of this modulation was too large to be explained as the change in light reflected or emitted by the planet. Aims. The MOST telescope continued to observe 55 Cnc e for a few weeks per year over five years, covering 143 individual transits. This paper presents the analysis of the observed phase modulation throughout these observations and a search for the secondary eclipse of the planet. Methods. The most important source of systematic noise in MOST data is due to stray-light reflected from the Earth, which is modulated with both the orbital period of the satellite and the Earth's rotation period. We present a new technique to deal with this source of noise, which we combined with standard detrending procedures for MOST data. We then performed Markov Chain Monte Carlo analyses of the detrended light curves, modeling the planetary transit and phase modulation. Results. We find phase modulations similar to those seen in 2011 in most of the subsequent years; however, the amplitude and phase of maximum light are seen to vary from 113 to 28 ppm and from 0.1 to 3.8 rad. The secondary eclipse is not detected, but we constrain the geometric albedo of the planet to less than 0.47 (2$σ$). Conclusions. While we cannot identify a single origin of the observed optical modulation, we propose a few possible scenarios. Those include star-planet interaction or the presence of a transiting circumstellar torus of dust. However, a detailed interpretation of these observations is limited by their photometric precision. Additional observations at optical wavelengths could contribute to uncovering the underlying physical processes.

description: A central question for neuroscience is how to characterize brain representations of perceptual and cognitive content. An ideal characterization should distinguish different functional regions with robustness to noise and idiosyncrasies of individual brains that do not correspond to computational differences. Previous studies have characterized brain representations by their representational geometry, which is defined by the representational dissimilarity matrix (RDM), a summary statistic that abstracts from the roles of individual neurons (or responses channels) and characterizes the discriminability of stimuli. Here we explore a further step of abstraction: from the geometry to the topology of brain representations. We propose topological representational similarity analysis (tRSA), an extension of representational similarity analysis (RSA) that uses a family of geo-topological summary statistics that generalizes the RDM to characterize the topology while de-emphasizing the geometry. We evaluate this new family of statistics in terms of the sensitivity and specificity for model selection using both simulations and fMRI data. In the simulations, the ground truth is a data-generating layer representation in a neural network model and the models are the same and other layers in different model instances (trained from different random seeds). In fMRI, the ground truth is a visual area and the models are the same and other areas measured in different subjects. Results show that topology-sensitive characterizations of population codes are robust to noise and interindividual variability and maintain excellent sensitivity to the unique representational signatures of different neural network layers and brain regions. These methods enable researchers to calibrate comparisons among representations in brains and models to be sensitive to the geometry, the topology, or a combination of both.

description: ProACO4–GUS expression and RT-PCR analysis revealed that ACO4 is predominantly expressed in shoots of Arabidopsis seedlings under light conditions. ACO4-overexpressed mutant 35S–ACO4 produced more ethylene relative to the wild-type, which resulted in reduced growth of Arabidopsis seedlings. The abnormal growth of seedlings recurred after the application of Co2+ ions, suggesting that ACO4 is a functional ACO necessary to regulate the growth and development of Arabidopsis seedlings. Exogenously-applied brassinosteroids (BRs) inhibited the expression of ACO4, and an enhanced ACO4 expression was found in det2, a BR-deficient mutant. Additionally, expression of ACO4 was decreased in bzr1-D (a BZR1-dominant mutant), implying that BR signaling negatively regulates ACO4 expression via BZR1 in Arabidopsis. In the intergenic region of ACO4, four E-boxes and a BR regulatory element (BRRE) are found. Electrophoretic mobility shift and chromatin immunoprecipitation assays showed that BZR1 binds directly to the BRRE in the putative promoter region of ACO4. By binding of BZR1 to BRRE, less ethylene was produced, which seems to regulate the growth and development of Arabidopsis seedlings.

description: We present a new prediction of the luminosity functions of the [CII] line at 158 $μ$m, of the CO lines from J=0 to J=24, and of the molecular gas mass density up to z=10, using the Spectro-Photometric Realisations of Infrared-selected Targets at all-z (SPRITZ) simulation (Bisigello et al. 2021). We update the state-of-the-art phenomenological simulation SPRITZ to include both the CO ($J\leq24$) and [CII] line luminosities. This has been performed using different empirical and theoretical relations to convert the total infrared luminosity (or star formation rate) to [CII] or CO luminosity. The resulting line luminosity functions have been compared for validation with a large set of observations available in the literature. We then used the derived CO and [CII] line luminosities to estimate the molecular gas mass density and compare it with available observations. The CO and [CII] luminosity functions presented here are well in agreement with all the available observations. In particular, the best results for [CII] are obtained deriving the [CII] luminosity directly from the star formation rate, but considering a dependence of this relation on the gas metallicity. For all the CO luminosity functions, the estimates favoured by the data are derived considering different relations, depending on the ionisation mechanism dominating each galaxy, i.e. star formation or active galactic nuclei, and, moreover, deriving the $J\geq4$ CO lines directly from the [CII] luminosity. However, further data are necessary to fully discriminate between models. Finally, the best agreement with observations of the molecular gas mass density are derived by converting the [CII] luminosity to H2 mass, using a [CII]-to-H2 conversion ~130 $\rm M_{\odot}/{\rm L}_{\odot}$. All the line luminosity functions, useful for planning and interpreting future observations, are made publicly available.

description: Infrared (IR) absorption spectroscopy has been used to probe the evolution of microscopic vibrational states upon the temperature- and photo-induced spin crossovers in [Fe(2-picolylamine)3]Cl2EtOH (Fe-pic). To overcome the small sizes and the strong IR absorption of the crystal samples used, an IR synchrotron radiation source and an IR microscope have been used. The obtained IR spectra of Fe-pic show large changes between high-spin and low-spin states for both the temperature- and the photo- induced spin crossovers. Although the spectra in the temperature- and photo-induced high-spin states are relatively similar to each other, they show distinct differences below 750 cm-1. This demonstrates that the photo-induced high-spin state involves microscopically different characters from those of the temperature-induced high-spin state. The results are discussed in terms of local pressure and structural deformations within the picolylamine ligands, and in terms of their possible relevance to the development of macroscopic photo-induced phase in Fe-pic.

description: With the local major cultivar Leccino as the control, the fruit quality, yield and early maturing property of introduced olive cultivars (Koroneiki, Arbequina, Hojiblanca) from Spain were studied. The results showed that there were differences in fruit traits such as single fruit weight, ratio of flesh content, moisture content and oil content between different cultivars. The yield of early maturing property of the introduce cultivars were better than those of Leccino. The introduced varieties can fruit after 1-2a, showing early maturity and high yield. This can provide a theoretical reference for the cultivation of olive in Longnan.

description: Fungal Biosynthetic Gene Clusters (BGCs) of secondary metabolites are clusters of genes capable of producing natural products, compounds that play an important role in the production of a wide variety of bioactive compounds, including antibiotics and pharmaceuticals. Identifying BGCs can lead to the discovery of novel natural products to benefit human health. Previous work has been focused on developing automatic tools to support BGC discovery in plants, fungi, and bacteria. Data-driven methods, as well as probabilistic and supervised learning methods have been explored in identifying BGCs. Most methods applied to identify fungal BGCs were data-driven and presented limited scope. Supervised learning methods have been shown to perform well at identifying BGCs in bacteria, and could be well suited to perform the same task in fungi. But labeled data instances are needed to perform supervised learning. Openly accessible BGC databases contain only a very small portion of previously curated fungal BGCs. Making new fungal BGC datasets available could motivate the development of supervised learning methods for fungal BGCs and potentially improve prediction performance compared to data-driven methods. In this work we propose new publicly available fungal BGC datasets to support the BGC discovery task using supervised learning. These datasets are prepared to perform binary classification and predict candidate BGC regions in fungal genomes. In addition we analyse the performance of a well supported supervised learning tool developed to predict BGCs.

description: The most popular face recognition benchmarks assume a distribution of subjects without much attention to their demographic attributes. In this work, we perform a comprehensive discrimination-aware experimentation of deep learning-based face recognition. The main aim of this study is focused on a better understanding of the feature space generated by deep models, and the performance achieved over different demographic groups. We also propose a general formulation of algorithmic discrimination with application to face biometrics. The experiments are conducted over the new DiveFace database composed of 24K identities from six different demographic groups. Two popular face recognition models are considered in the experimental framework: ResNet-50 and VGG-Face. We experimentally show that demographic groups highly represented in popular face databases have led to popular pre-trained deep face models presenting strong algorithmic discrimination. That discrimination can be observed both qualitatively at the feature space of the deep models and quantitatively in large performance differences when applying those models in different demographic groups, e.g. for face biometrics.

The results showed that the anthocyanins from flowers of R. pulchrum were relatively stable in the room with natural light, at temperature lower than 45℃, and in the solution with pH ≤ 4. The addition of Na+, K+ Ca2+ metal ions, glucose, sodium benzoate, acetic acid and salt had little effect, but Cu2+, Zn2+, Fe3+, Al3+, starch and sodium glutamate showed adverse effects on the stability of the anthocyanins. The anthocyanins from flowers of R. pulchrum had a good antioxidant effect, and their scavenging capacity for •OH, O2-•, DPPH• was better than that of the same concentration of Vc.

description: Nonlinear boolean equation systems play an important role in a wide range of applications. Grover's algorithm is one of the best-known quantum search algorithms in solving the nonlinear boolean equation system on quantum computers. In this paper, we propose three novel techniques to improve the efficiency under Grover's algorithm framework. A W-cycle circuit construction introduces a recursive idea to increase the solvable number of boolean equations given a fixed number of qubits. Then, a greedy compression technique is proposed to reduce the oracle circuit depth. Finally, a randomized Grover's algorithm randomly chooses a subset of equations to form a random oracle every iteration, which further reduces the circuit depth and the number of ancilla qubits. Numerical results on boolean quadratic equations demonstrate the efficiency of the proposed techniques.

description: We show that a single-mode squeeze operator S(z) being an unitary operator with a purely continuous spectrum gives rise to a family of discrete real generalized eigenvalues. These eigenvalues are closely related to the spectral properties of S(z) and the corresponding generalized eigenvectors may be interpreted as resonant states well known in the scattering theory. It turns out that these states entirely characterize the action of S(z). This result is then generalized to N-mode squeezing.

description: We report the results of a study of the di erential magnetic susceptibility of Sr3Ru2O7 as a function of temperature and magnetic elds applied at a series of angles to the ab plane. By analysing the real and imaginary parts of the susceptibility, we conclude that the eld angle acts as a continuous tuning parameter for the critical end-point to a line of rst order metamagnetic phase transitions. The end-point sits at approximately 1.25K for elds applied in the ab plane, and is depressed to below 50 mK when the eld is aligned within 10 of the c axis.

description: We started a survey with CHARA/MIRC-X and VLTI/GRAVITY to search for low mass companions orbiting individual components of intermediate mass binary systems. With the incredible precision of these instruments, we can detect astrometric "wobbles" from companions down to a few tens of micro-arcseconds. This allows us to detect any previously unseen triple systems in our list of binaries. We present the orbits of 12 companions around early F to B-type binaries, 9 of which are new detections and 3 of which are first astrometric detections of known RV companions. The masses of these newly detected components range from 0.45-1.3 solar masses. Our orbits constrain these systems to a high astrometric precision, with median residuals to the orbital fit of 20-50 micro-arcseconds in most cases. For 7 of these systems we include newly obtained radial velocity data, which help us to identify the system configuration and to solve for masses of individual components in some cases. Although additional RV measurements are needed to break degeneracy in the mutual inclination, we find that the majority of these inner triples are not well-aligned with the wide binary orbit. This hints that higher mass triples are more misaligned compared to solar and lower mass triples, though a thorough study of survey biases is needed. We show that the ARMADA survey is extremely successful at uncovering previously unseen companions in binaries. This method will be used in upcoming papers to constrain companion demographics in intermediate mass binary systems down to the planetary mass regime.

description: We study one- and two-soliton solutions of noncommutative Chern-Simons theory coupled to a nonrelativistic or a relativistic scalar field. In the nonrelativistic case, we find a tower of new stationary time-dependent solutions, all with the same charge density, but with increasing energies. The dynamics of these solitons cannot be studied using traditional moduli space techniques, but we do find a nontrivial symplectic form on the phase space indicating that the moduli space is not flat. In the relativistic case we find the metric on the two soliton moduli space.

description: In this paper, we consider the exterior algebra $Λ(W)$ of a polynomial $\mathrm{GL}(n)$-module $W$ and use previously developed methods to determine the Hilbert series of the algebra of invariants $Λ(W)^G$, where $G$ is one of the classical complex subgroups of $\mathrm{GL}(n)$, namely $\mathrm{SL}(n)$, $\mathrm{O}(n)$, $\mathrm{SO}(n)$, or $\mathrm{Sp}(2d)$ (for $n=2d$). Since $Λ(W)^G$ is finite dimensional, we apply the described method to compute a lot of explicit examples. For $Λ(S^3\mathbb{C}^3)^{\mathrm{SL}(3)}$, using the computed Hilbert series, we obtain an explicit set of generators.

description: This study aimed to explore an analysis method for baicalin in Scutellaria baicalensis Georgi and make a reference for the analysis of the medicinal value of S. baicalensis cultivated in Jizhou District. The content of baicalin in S. baicalensis cultivated in Jizhou District was determined using high-performance liquid chromatography (HPLC) to judge whether it met the requirements of Chinese Pharmacopoeia; and according to the requirements of the Chinese Pharmacopoeia of 2015 edition, the contents of heavy metals were determined by ICP-MS. The results showed that the contents of baicalin, Cr, Cu, As, Cd and Pb in S. baicalensis planted in Jizhou District were 14.625 05%, 11.360 12.830 , 0.062 315 , 0.025 715 and 0.176 65 μg/g, respectively. The content of baicalin in S. baicalensis planted in Jizhou District was much higher than the standard (≥ 9.0%) of Chinese Pharmacopoeia of 2015 edition, and the contents of heavy metals were also below the limit (≤20/1 000 000) required by Chinese Pharmacopoeia of 2015 edition.

description: Circularly polarized laser field causes a shift in the nuclear magnetic resonance (NMR) spectra of all substances. The shift is proportional to the intensity of the laser beam and yields oppositely signed values for left- and right-circularly polarized light, CPL -/+, respectively. Rapid switching -- in the NMR time scale -- between CPL+ and CPL- gives rise to a splitting of the NMR resonance lines. We present uncorrelated and correlated quadratic response calculations of the splitting per unit of beam intensity in the NMR spectra of $^{21}$Ne, $^{83}$Kr, and $^{129}$Xe. We study both the regions far away from and near to optical resonance and predict off-resonance shifts of the order 0.01, 0.1, and $1\times 10^{-6}$ Hz for $^{21}$Ne, $^{83}$Kr, and $^{129}$Xe, respectively, for a beam intensity of 10 W/cm$^2$. Enhancement by several orders of magnitude is predicted as the beam frequency approaches resonance. Only then can the effect on guest $^{129}$Xe atoms be potentially useful as a probe of the properties of the host material.

description: This paper studied effects of different picking time and different geographical provenances on oil content of Camellia oleifera. The results showed that different picking time had significant effects on the oil content of cold dew seeds and frost's descent seeds. With the delay of picking time, the oil content of cold dew seeds, frost's descent seeds, dry seeds and oil content of seed kernels were significantly increased. There was a significantly positive correlation between the oil content of fresh fruit of cold dew seeds and frost's descent seeds and the dry seed yield of fresh seeds and the oil content of fresh fruit (P < 0.05), and the correlation coefficient was greater than 0.85. Besides, the oil content of seed kernels of cold dew seeds was closely correlated with the seed yield of fresh seeds, oil content of fresh fruit, and oil content of fresh seeds. In the process of C. oleifera breeding, the thin coat, high seed yield and high oil content can be taken as the key research directions for future breeding. The oil content of ordinary C. oleifera seeds in 18 counties (cities) was 36.42%-63.33%, indicating that there were significant differences in the oil content of C. oleifera in different geographical provenances. In conclusion, according to the study of different picking time, the recommended picking time of cold dew seeds in Hunan area is around October 10, while the best picking time of frost's descent seeds is about October 30. The oil content of C. oleifera fruit in different geographical provenances is quite different. During the development of C. oleifera fruit, the cultivation and management of C. oleifera should be strengthened to increase the oil content of C. oleifera.
