description: In this manuscript, RDX (Royal Demolition eXplosive) and HMX (High Melting eXplosive) were removed from water that is mainly polluted by military activities. Two different forms of magnetic graphene oxide nanocomposites, α-Fe2O3-rGO (hematite-reduced graphene oxide) and nZVI-rGO (nano zero valent iron-reduced graphene oxide) have been evaluated for decontamination of water containing these carcinogenic explosives. Comparative adsorption studies were carried out considering contact time, pH and adsorbent dosage for all the adsorbent–adsorbate systems. Batch adsorption experiments at varied concentrations of RDX and HMX were conducted. The experimental results better fit in pseudo second order model following Freundlich isotherm. Magnetic nature of both adsorbents is suitable for their easy separation from contaminated water in presence of an external magnetic field. α-Fe2O3-rGO showed higher adsorption capacities for HMX and RDX, this was supported by the physio-chemical properties of the adsorbent. Therefore, it could be potentially upscaled and used commercially for purification of water containing explosives.

description: We realize the physical N-anyon Hilbert spaces, introduced previously via unitary representations of the group of diffeomorphisms of the plane, as N-fold braided-symmetric tensor products of the 1-particle Hilbert space. This perspective provides a convenient Fock space construction for nonrelativistic anyon quantum fields along the more usual lines of boson and fermion fields, but in a braided category. We see how essential physical information is thus encoded. In particular we show how the algebraic structure of our anyonic Fock space leads to a natural anyonic exclusion principle related to intermediate occupation number statistics, and obtain the partition function for an idealised gas of fixed anyonic vortices.

title: Development of a chick embryo model to study important regulatory domains of human genes implicated in Motor Neurone Disease
Creators: name: Khursheed, KN
Publisher: name: University of Liverpool Repository
Year: 2017

description: Abstract Motor neurone disease refers to a group of neurological disorders that result from progressive degeneration of the motor neurones leading to death from respiratory failure within 3-5 years from the onset of symptoms. Amyotrophic lateral sclerosis (ALS) is one of the most common forms of motor neurone disease, and can be described as entailing the involvement of both upper and lower motor neurones. Usually, the disease is obvious and presents as asymmetrical weakness in the limbs and progressive muscular atrophy. Over the last two decades more than 30 genes have been identified as involved in ALS pathology. These include PARK7 and FUS (Fused in sarcoma) which are the subject of this thesis. FUS is a multifunctional protein that has ubiquitous expression and is involved in different steps of RNA processing such as mRNA and miRNA. 10% of ALS cases are heritable and mutation of the FUS gene is found in 3-5% of familial forms of ALS. Therefore the FUS gene is important for it association as a candidate gene that is postulated to be important for ALS, in addition to various types of cancer. Mutations with FUS gene have been found in autopsy samples from the brain and spinal cord of patients with ALS. Understanding the regulation of FUS gene expression may, therefore, give insights into how its stimulus inducible expression may be associated with neurological disorders. My hypothesis is that the evolutionary conserved regions (ECRs) and primate specific retrotransposons of the SINE-VNTR Alu (SVA) are regulatory domains from the human FUS gene and PARK7 genes. Consequently, the aim of this thesis was to develop an in vivo model to validate their regulation. Comparative genomic analysis was used between distant species, utilizing the ECR browser and UCSC browser to identify conserved regions from the FUS gene. It is demonstrated that ECR and SVA, xviii which can drive reporter gene activity in vitro (in the neuroblastoma cell line), are also capable of driving reporter gene expression in the chick embryo neural tube and brain at embryonic day 5. In conclusion, these identified important ECRs from human FUS gene act as regulatory domains. In addition, the SVAs, representing the most recent retrotransposon to enter the human genome also was showed to have regulatory properties in FUS and PARK7 genes. Furthermore, the thesis demonstrates that these elements regulate gene expression in vitro and in vivo. This supports the idea that employment of the chick embryo as a useful and informative model system to analyse mammalian gene regulation.

description: Using a unique Swedish database that records the ultimate stockholdings in public firms, we decompose stock ownership by domiciles using votes rather than cashflows. We then study the impact of variables related to the lifecycle theory of dividends and the catering theory of dividends. We also examine the propensity of firms to pay dividends and/or activate a stock buyback program. Univariate analysis reveals a positive association between a firm's maturity and its likelihood to pay dividends. Logistic regression finds a positive relation between payouts and retained earnings to total assets. Foreign institutional investors are less likely to hold dividend-paying stocks than domestic institutional investors. The analysis finds no support for the catering theory of dividends. After controlling for stock ownership, our evidence is consistent with the lifecycle theory of dividends, which states that more mature firms are associated with dividends. It also supports the transaction cost hypothesis claiming that foreign investors face additional administrative costs when holding dividend-paying stocks.

description: The paper deals with the issues of the analysis of the actual state in decision support systems in the companies in the Slovak Republic with the aim to suggest recommendations in this field. The object of our concern was mainly in the following fields: sources of requisite information in decision making and their forms, methods of obtaining information, and utilization of particular types of information systems in support of decision systems. Managers get mass of data which should make the decision making process easier, however they are frequently encumbered by a number of unusable data of poor quality. They would appreciate different type and form of the supplied data. The result of the research also referred to insufficiently and inconveniently projected information systems (not only computer information systems), as well as the question of company know-how loss. It was revealed that the information potential of subordinates is used insufficiently. In spite of the existence of the abundant number of methods for the support of decision making processes, the use of them was insufficient.

description: We study homogeneous curves in generalized flag manifolds $G/K$ with $G_2$-type $t$-roots, which are geodesics with respect to each $G$-invariant metric on $G/K$. These curves are called equigeodesics. The tangent space of such flag manifolds splits into six isotropy summands, which are in one-to-one correspondence with $t$-roots. Also, these spaces are a generalization of the exceptional full flag manifold $G_2/T$. We give a characterization for structural equigeodesics for flag manifolds with $G_2$-type $t$-roots, and we give for each such flag manifold, a list of subspaces in which the vectors are structural equigeodesic vectors.

The identification of mentioned possibilities is realized on the basis of the multidimensional 55 NUTS2 classification according to the initial GDP level and average GDP growth rate in the time period 1998--2004. The results of realized analyses show that from the point of view of balancing socio-economic disparities it is possible to talk rather about divergence tendencies of the economic level of the new EU member regions than convergence tendencies.
title: Establishment of a functional musculoskeletal test system in mice to determine the effects of possible interventions on age-related musculoskeletal dysfunction
Creators: name: Nye, G
Publisher: name: University of Liverpool Repository
Year: 2017

description: The age-related loss of skeletal muscle mass and function is a key contributor to physical frailty in older individuals. In addition to this, the increased development of bone and joint disorders such as osteoporosis and osteoarthritis with ageing present a complex problem. Current understanding of the mechanisms responsible for age-related musculoskeletal deterioration is poor. The overall aims of this study were to integrate methods of measuring and visualising age-related changes in musculoskeletal tissues in a mouse model of ageing and to test a range of differing potential interventions known to protect individual tissues during ageing on the whole musculoskeletal system. Data demonstrated that C57Bl6 mice are a reliable model to study ageing, particularly in muscle and bone (Muscle mass reduced by ~40% and trabecular bone halved between 3 and 28 months of age); however these mice did not demonstrate evidence of any gross changes in the hind limb joints or tendons. C57Bl/6 mice were supplemented dietary sodium nitrate for either a short (18-24 months old) or longer (9 to 24 months old) to determine whether supplementation at key stages of development of musculoskeletal tissue dysfunction would result in preservation of muscle or bone without the need for more invasive treatment. No significant differences were reported in the long term treatment, however short-term treatments of mice with nitrate resulted in a significant decrease in muscle mass and function and this was associated with changes in trabecular bone disputing our initial hypothesis. HSP10 overexpression in muscles of mice has been shown to preserve muscle force generation and cross-sectional area in old mice previously. As proof of principle, the direct effect of such preservation of muscle on bone was tested. Preservation of muscle was evident as in the previous study; however, little effect of this was seen on bone disputing the dominant role the muscle has over bone tissue. A cohort of wild mice was then used to challenge the widely used Bl/6 mouse model and demonstrated substantial spontaneous deterioration of joint tissues as well as increased loss of muscle and bone tissue compared to the Bl/6 mice. These results indicated a possible altered ageing process in the lab bred C57Bl/6 mouse which may impact the research using them.
Thirlwall’s law is not a tautology, but some empirical tests of it nearly are

Year: 2023

description: This article examines the charge that Thirlwall's law is a theoretical tautology. It shows that a certain approach to empirical testing of that law can sometimes – under conditions analysed here – result in econometric estimates that reflect an approximate identity or ‘near-tautology’. Nevertheless, other methods of empirically testing the law are not subject to the near-tautology critique, and hence the theory itself is not a tautology. Econometric estimates for the US and Mexico reveal that the near-tautology critique applies to data for the former but not the latter; the difference in these results is explained by exactly the reasons discussed here. The article offers an alternative interpretation of Thirlwall's law as implying a benchmark for analysing whether national income, rather than relative prices, is the main adjusting factor in response to current-account imbalances in the long run.

description: In Western Europe, USA, and other developed countries agriculture is dominated by small family farms. In Central and Eastern European Countries (CEEC), and Former Soviet Union (FSU) dual structure of farms exists. There are large corporate farms (CF) and small family farms (FF) in CEEC and FSU. Our paper shows that both CFs and FFs specialize in commodities in which they have comparative advantage. CFs specialize in capital intensive products and in products with low labor monitoring. FFs specialize in products with higher labor monitoring requirements. The results of the research shown in this paper prove that farm structure determines the products of the country which will be competitive on international markets. This is especially important for transition countries, where high transaction costs hinder the change of farm organization. For this reason the choice of product structure in transition countries suffering from high transaction cost is more important than the choice of farm organization.

description: To understand the genetic diversity and dispersal history of Schlegel’s Japanese gecko (Gekko japonicus), we performed genetic analyses and paleo-species distributional modelling. For the genetic analysis, we analyzed mitochondrial DNA (mtDNA) (cytochrome b [Cytb] and NADH dehydrogenase 2 [ND2]) and seven microsatellite loci of 353 individuals from 11 populations (2 east coast China, 4 west and central coast Japan and 5 Korea). For the paleo-species distribution modelling, we used 432 occurrence data points (125 China, 291 Japan and 16 Korea) over the Pleistocene and Holocene. China is inferred to be the source population, which had higher genetic diversity (mtDNA) and more private alleles (mtDNA) compared to Japanese and Korean populations. Differences between the three counties were very small in the mtDNA haplotype network despite some genetic structure among the three countries. Microsatellite analysis inferred that genetic exchange has actively occurred among the Chinese, Japanese and Korean populations. Suitable habitats in Japan should have been plentiful by the mid-Holocene, but have only recently become available in Korea. These results suggest that dispersal of G. japonicus occurred after the Holocene warming from the east coast of China to the west and central coasts of Japan and Korea, and gene flow is actively occurring among the three countries.

description: We present the first satellite system of the Large Binocular Telescope Satellites Of Nearby Galaxies Survey (LBT-SONG), a survey to characterize the close satellite populations of Large Magellanic Cloud to Milky Way-mass, star-forming galaxies in the Local Volume. In this paper, we describe our unresolved diffuse satellite finding and completeness measurement methodology and apply this framework to NGC 628, an isolated galaxy with $\sim1/4$ the stellar mass of the Milky Way. We present two new dwarf satellite galaxy candidates: NGC 628 dwA, and dwB with $\text{M}_{\text{V}}$ = $-12.2$ and $-7.7$, respectively. NGC 628 dwA is a classical dwarf while NGC 628 dwB is a low-luminosity galaxy that appears to have been quenched after reionization. Completeness corrections indicate that the presence of these two satellites is consistent with CDM predictions. The satellite colors indicate that the galaxies are neither actively star-forming nor do they have the purely ancient stellar populations characteristic of ultrafaint dwarfs. Instead, and consistent with our previous work on the NGC 4214 system, they show signs of recent quenching, further indicating that environmental quenching can play a role in modifying satellite populations even for hosts smaller than the Milky Way.

description: It is shown how to solve the Euclidean equations of motion of a point particle in a general potential and in the presence of a four-Fermi term. The classical action in this theory depends explicitly on a set of four fermionic collective coordinates. The corrections to the classical action due to the presence of fermions are of topological nature in the sense that they depend only on the values of the fields at the boundary points $τ\to \pm \infty$. As an application, the Sine-Gordon model with a four-Fermi term is solved explicitly and the corrections to the classical action are computed.

For evaluation of this situation there were used selected financial indicators, development of which was accounted in the period 2000-2005. The base of the data vere created, by aggregate data of corporate bodies. Data comes from the VU EPP database. Indebtedness of agricultural farms reaches in average 35 %. In accordance with an average Slovak company, which indebtedness is 75 %, and in accordance with direction value 50 % it is still under the tolerable value. Lower indebtedness of agricultural farms results from specific factors of agricultural basic industry. These factors are land and climatic conditions, seasonality of production, lower profit margin, and long cycle of production, which means distinction between production and sales phase that causes ups and downs in cash flows of the companies. The relationship between profitability and indebtedness shows non-linear development in the period 2000-2005.

description: Nowadays, primary productivity variations at the SW Iberian Margin (IbM) are primarily controlled by wind-driven upwelling. Thus, major changes in atmospheric circulation and wind regimes between the Marine Isotope Stages (MIS) 12 and 9 could have driven substantial changes in phytoplankton productivity which remains poorly understood. We present a high-resolution calcareous nannofossil record from the Shackleton Site Integrated Ocean Discovery Program Site U1385 that allow the assessment of primary productivity and changing surface conditions on orbital and suborbital timescales over the SW IbM. These records are directly compared and integrated with terrestrial – Mediterranean forest pollen – and marine – benthic and planktic oxygen stable isotopes (δ18O), alkenone concentration [C37], Uk´37-Sea Surface Temperature and % C37:4 – proxy records from Site U1385. Our results indicate intra-interglacial increase in primary productivity together with intensification of the Azores anticyclonic high-pressure cell beyond the summer that suggests a two-phase upwelling behavior during the full interglacial MIS 11c (∼420–397 ka), potentially drived by atmospheric NAO-like variability. Primary productivity is largely enhanced during the inception of glacial MIS 10 and the early MIS 10 (∼392–356 ka), linked to intensified upwelling and associated processes during a period of strengthened atmospheric circulation. In agreement with the conditions observed during Heinrich events of the last glacial cycle, primary productivity reductions during abrupt cold episodes, including the Heinrich-type (Ht) events 4 to 1 (∼436, 392, 384 and 339 ka) and the Terminations V and IV, seems to be the result of halocline formation induced by meltwater arrival, reducing the regional upward nutrient transference.

description: Abstract

Survey research on sexual identity often categorizes respondents as heterosexual, homosexual, and bisexual, but may miss more nuanced identities. Recent Federal recommendations regarding best practices for the measurement of sexual identity have called for the inclusion of “something else” response options. Prior research has suggested that estimates of health disparities between sexual identity subgroups can be affected if a “something else” response option is not provided, given that respondents who do not identify as heterosexual, homosexual, or bisexual may be forced to select one of these options even if they do not see them as being relevant. Unfortunately, some surveys lack this option. We propose an innovative method using random forests to predict four-category sexual identity based on surveys that provide these options, followed by the prediction of four-category sexual identity responses in surveys that do not include these categories but do include common covariates to construct the “unobserved” identities retrospectively. We utilize bootstrap resampling to capture uncertainty with this prediction process. Leveraging a split-ballot experiment in the 2015-2019 National Survey of Family Growth, we first fit benchmark models of interest to selected health outcomes as a function of sexual identity in the half-sample including “something else” as a response category. Using this as a training data set, we then develop a classifier for four-category sexual identity, and use the half-sample excluding “something else” as a test data set, where we develop predictions of four-category sexual identity and then use these predictions to estimate the models of interest. We repeat this process for each of several hundred bootstrap samples, and evaluate the ability of this methodology to recover the model of interest based on four sexual identity categories in the data set that did not offer them.

description: Motivated by a recent proposal for an experimental verification of the dynamical Casimir effect, the macroscopic electromagnetic field within a perfect cavity containing a thin slab with a time-dependent dielectric permittivity is quantized in terms of the dual potentials. For the resonance case, the number of photons created out of the vacuum due to the dynamical Casimir effect is calculated for both polarizations (TE and TM).

description: We report on the experimental and theoretical investigation of magnetic-field-induced second harmonic generation (SHG) and two-photon absorption (TPA) of excited exciton states ($n \geq 3$) of the yellow series in Cu$_2$O. In this centrosymmetric material, SHG can occur due to constructive interplay of electric dipole and electric quadrupole/magnetic dipole transitions for light propagating along the low-symmetry directions [111] or [112]. By application of a magnetic field in Voigt configuration, SHG gets also allowed for excitation along the [110]-axis and even the high-symmetry cubic direction [001]. Combining a symmetry analysis and a microscopic theory, we uncover the two key contributions to the magnetic-field-induced SHG: the Zeeman effect and the magneto-Stark effect. We demonstrate systematic dependencies of the SHG intensity on the linear polarization angles of the ingoing fundamental laser and the outgoing SHG beam. In general, the resulting contour plots in combination with a symmetry analysis allow one to determine uniquely the character of involved transitions. Moreover, we can separate in magnetic field the Zeeman and the magneto-Stark effect through appropriate choice of the experimental geometry and polarization configuration. We present a microscopic theory of the second harmonic generation of excitons in a centrosymmetric cubic semiconductor taking into account the symmetry and the band structure of cuprous oxide. Based on the developed microscopic theory we identify the main contributions to the second-order nonlinear susceptibility of $S$-, $P$- and $D$-excitons. We analyze the redistribution of SHG intensities between the excitonic states both in the absence and presence of the magnetic field and show good agreement with the experimental data. With increasing exciton principal quantum number the magneto-Stark effect overpowers the influence of the Zeeman effect.
