Deep Photography of Radio Sources with the Cambridge CCD System

We present preliminary results from a programme designed to produce deep images of radio source fields drawn from the Parkes 2700 MHz and Molongolo 408 MHz catalogues using the charge-coupled-device (CCD) camera system built at the Institute of Astronomy, Cambridge. The programme is directed at a search both for faint extensions and nebulosity around radio QSOs and BL Lac objects and for faint objects in otherwise empty radio source fields; a detailed examination of the morphology of selected radio galaxies is also included.
The Metal-Rich Universe: Chemical evolution of the Galactic bulge

Adopting a single-zone framework, with accretion of primordial gas on a free-fall timescale, the chemical evolution of the Galactic bulge is calculated, assuming (i) a corresponding rapid timescale for star formation, and (ii) an initial mass function biased towards massive stars. We emphasise here the uncertainties associated with the underlying physics (specifically, stellar nucleosynthesis) and how those uncertainties are manifest in the predicted abundance ratio patterns in the resulting present-day Galactic bulge stellar populations.
Challenges of identifying putative planetary-origin meteorites composed of non-igneous material

This concept article discusses the challenges of identifying planetary-origin meteorites of non-igneous composition, primarily of sedimentary origin, distinct from SNC meteorites. The paper reviews evidence on putative sedimentary-origin meteorites and potential parent bodies for sedimentary meteorites. Authors conclude that the list of candidate parent bodies for sedimentary meteorites includes, but is not limited by the Earth, Mars, Enceladus, Ganymede, Europa, and hypothetical planets that could exist between orbits of Mars and Jupiter in the past. Authors argue that extraterrestrial origin and a parent body for meteoritic sedimentary rocks may be identified based on the entire body of evidence which is not limited solely by tests of oxygen and noble gas isotopes whose signatures may undergo terrestrial contamination and may exhibit significant heterogeneity within the Solar system and within the parent cosmic bodies. Observed fall of a cosmic body, evidence of hypervelocity fall, signs of impact in target, and the presence of fusion crust, melting, and/or shock deformation features in the fragments should be considered as priority signs of meteoritic origin.
Using Gaussian Processes for Rumour Stance Classiﬁcation in Social Media

Social media tend to be rife with rumours while new reports are released piecemeal during breaking news. Interestingly, one can mine multiple reactions expressed by social media users in those situations, exploring their stance towards rumours, ultimately enabling the ﬂagging of highly disputed rumours as being potentially false. In this work, we set out to develop an automated, supervised classiﬁer that uses multi-task learning to classify the stance expressed in each individual tweet in a rumourous conversation as either supporting, denying or questioning the rumour. Using a classiﬁer based on Gaussian Processes, and exploring its effectiveness on two datasets with very different characteristics and varying distributions of stances, we show that our approach consistently outperforms competitive baseline classiﬁers. Our classiﬁer is especially effective in estimating the distribution of different types of stance associated with a given rumour, which we set forth as a desired characteristic for a rumour-tracking system that will warn both ordinary users of Twitter and professional news practitioners when a rumour is being rebutted.
Comparative Transcriptomic Analysis of Streptococcus thermophilus TH1436 and TH1477 Showing Different Capability in the Use o f Galactose

Streptococcus thermophilus is a species widely used in the dairy industry for its capability to rapidly ferment lactose and lower the pH. The capability to use galactose produced from lactose hydrolysis is strain dependent and most of commercial S. thermophilus strains are galactose-negative (Gal − ), although galactose-positive (Gal + ) would be more technologically advantageous because this feature could provide additional metabolic products and prevent galactose accumulation in foods. In this study, a next generation sequencing transcriptome approach was used to compare for the ﬁrst time a Gal + and a Gal − strain to characterize their whole metabolism and shed light on their different properties, metabolic performance and gene regulation. Transcriptome analysis revealed that all genes of the gal operon were expressed very differently in Gal + and in the Gal − strains. The expression of several genes involved in mixed acid fermentation, PTS sugars transporter and stress response were found enhanced in Gal + . Conversely, genes related to amino acids, proteins metabolism and CRISPR associated proteins were under-expressed. In addition, the strains showed a diverse series of predicted genes controlled by the transcriptional factor catabolite control protein A (CcpA). Overall, transcriptomic analysis suggests that the Gal + strain underwent a metabolic remodeling to cope with the changed environmental conditions.
OF THE DISSERTATION Rigidiﬁcation of Algebras Over Algebraic Theories in Diagram Categories by

The notion of an algebraic theory, which is able to describe many algebraic structures, has been used extensively since its introduction by Lawvere in 1963. This perspective has been very fruitful for understanding in a wide variety of algebraic structures, including rigidiﬁcation results for simplicial algebras over algebraic theories by Badzioch and Bergner. In this thesis, we extend the rigidiﬁcation results to algebras over a larger class of categories, which includes bisimplicial sets. In particular, we prove the rigidiﬁcation result is true in any diagram category SS ets C op for a small category C .
Topical Anti-TNFα Agent Licaminlimab (OCS-02) Relieves Persistent Ocular Discomfort in Severe Dry Eye Disease: A Randomized Phase II Study

Purpose To assess the efficacy, safety, and pharmacokinetics of new topical ocular anti-TNFα antibody fragment licaminlimab in the relief of persistent ocular discomfort in severe dry eye disease (DED). Patients and Methods Patients with ≥6-month history of DED, regular use of artificial tears, and best-corrected visual acuity (BCVA) of ≥55 letters in each eye (Early Treatment Diabetic Retinopathy Score) at baseline were included in this multicenter, randomized, vehicle-controlled, double masked study. A total of 514 patients were screened. After a 2-week run-in with Vehicle, all qualifying patients received Vehicle eye drops for 4 weeks. Patients with global ocular discomfort score ≥50 at the end of this 4-week period were randomized to receive licaminlimab (60 mg/mL ophthalmic solution) (69 patients) or Vehicle (65 patients) for 6 weeks. The primary efficacy endpoint was change from baseline in global ocular discomfort score at Day 29. Safety assessments included adverse events and ophthalmology examination including intraocular pressure (IOP). Serum licaminlimab levels were also determined. Results Change from baseline to Day 29 in global ocular discomfort score was statistically significantly greater for licaminlimab than for Vehicle (p = 0.041). No safety issues were identified. Serum licaminlimab was undetectable in most patients; the maximum concentration observed was 8.47 ng/mL. Conclusion Topical ocular licaminlimab demonstrated statistically significant improvement in global ocular discomfort score compared to Vehicle in patients with severe DED, with good tolerability, no increase in IOP, and minimal systemic drug exposure.
Influence of the Perception of Data Security and Security Importance on Customer Usage of Internet Services

—An increasing customer usage of Internet services with various devices demands a greater effort on data security and privacy issues, because more and more devices are connected and much personal information are spread more widely. However, in many cases the performance of services is more important than the provision of data security. Therefore, it would be necessary to investigate how the user perception of data security influences the usage of Internet services, which will be analyzed with a adjusted combined approach of the Technology Acceptance Model and the second model of the Unified Theory of Acceptance and Use of Technology. To support the analysis of this conceptual relationship, an evaluation of the interrelation between the perceived data security importance and the user behavior is also examined. The aim of this paper is to figure out a possible negative impact of the perception of data security and security importance on the usage of Internet services. The goal of the paper is to prove an influence of data security within an adjusted conceptual model based on the Technology Acceptance Model and the second model of the Unified Theory of Ac-ceptance and Use of Technology. In general, a significant relationship between the perceived data security, perceived data security importance and user behavior of Internet services cannot be found. Particularly, some regressive influences are proved in the perceptions of data security importance and usage of specific services. The primary result of this paper is that from the perspective of customers the general perceived data security is significantly most influenced by the perceived email accounts security.
A new macro stress testing approach for ﬁnancial realignment in the Eurozone Journal of International Financial Markets, Institutions & Money

Contrary to the common approach of stress-testing under which banks are evaluated whether they are distressed, this empirical study chooses to move from the micro stress test approach to a wider new macro stress test category. By being able to stress testing the entire economy of the Eurozone, it will permit big banks to fail and, at the same time, will open room for new banking players to enter the sector, promoting the essence of a healthy destruction. The analysis performs a battery of stress tests, by implementing VaR, Cornish-Fisher VaR, Monte Carlo VaR, Expected Shortfall, Cornish-Fisher Expected Shortfall, and Monte Carlo Expected Shortfall. At the same time, it explicitly considers the new regulatory approach of IFRS9 to incorporate extreme values from forecasted series in the distributions. The analysis also performs two versions of stress tests, one including TARGET2 and one without it. The results document that future stress tests should include TARGET2 values in order to capture a better picture of the stressed economy. The ﬁndings from these stress tests clearly illustrate that although there has been a trough after the dis- tress call of 2008, this trough ended. These are results derived without including the TARGET2 transfers. By including the TARGET2 transfers we receive a different picture that possibly acts as a protective mechanism against any future crisis. Caution is still advised, possibly due to some lingering imbalances within the Eurozone. (cid:1) 2019 Elsevier B.V. All rights reserved.
Modeling Driver Merging Behavior: A Repeated Game Theoretical Approach

Various lane-changing models have been developed for use within microscopic traffic simulation software to replicate driver merging behavior. An understanding of human driving behavior, which can be gained through such modeling, will be critical in harmonizing emerging advanced vehicle technology, such as connected automated vehicles, with human drivers. Therefore, it is important to ensure that lane-changing models are clearly understood, appropriately designed, and carefully calibrated. An earlier study by Kang and Rakha proposed and developed a decision-making model for merging maneuvers using a game theoretical approach considering two drivers: the driver of the subject vehicle (DS) in an acceleration lane and the driver of the following lag vehicle (DL) in the target lane. The previous model assumed that the DS and DL decide on an action at the first point only, where the subject and lag vehicles are identified. The current study extends the Kang and Rakha model by introducing the concept of a repeated game, assuming that a lane change decision is made repeatedly to adjust to changes in surrounding conditions. For example, drivers often decide to change their initial decision as a result of conflicts with other drivers. A repeated game helps the proposed model produce more realistic decision-making in the lane-changing process. To evaluate the model, driver decisions at a certain stage, along with accumulated historical decision data, were extracted from Next Generation SIMulation (NGSIM) data. The validation results reveal that the proposed repeated game model produces considerable prediction accuracy (above 75%).
Adhesion Molecule Deﬁciencies Increase Porphyromonas gingivalis Induced Alveolar Bone Loss in Mice

Alveolar bone resorption can be induced in speciﬁc-pathogen-free mice by oral infection with Porphyromonas gingivalis (P. J. Baker, R. T. Evans, and D. C. Roopenian, Arch. Oral Biol. 39:1035–1040, 1994). Here we used a mouse strain, C57BL/6J, which is relatively resistant to P. gingivalis -induced bone loss to examine whether partial or complete deletion of various adhesion molecules would increase susceptibility. Complete deletion of P-selectin or nearly complete lack of expression of intercellular adhesion molecule 1 (ICAM-1) led to increased susceptibility to bone resorption after oral infection, while a hypomorphic defect in b 2 -integrins did not. Both the total amount of bone lost and the number of sites at which there was signiﬁcant loss were increased in mice deﬁcient in either ICAM-1 or P-selectin. Each of the three adhesion molecule deﬁciencies was sufﬁcient to decrease P. gingivalis -speciﬁc serum immunoglobulin G responses, but lower antibody titers did not lead to increased bone loss in partially b 2 -integrin-deﬁcient mice. In conclusion, P-selectin and ICAM-1 deﬁciencies increase susceptibility to and severity of alveolar bone loss after
WOULD MEETINGS BETWEEN THE BOARD OF DIRECTORS AND THE SHARIAH SUPERVISORY BOARD AFFECT THE FINANCIAL PERFORMANCE OF ISLAMIC BANKS?

This research paper aims to examine the relationship between the Board of Directors and the Shariah Board and to investigate its impact on the financial performance of Islamic banks. We employ regression analyzes to study the impact of the feature connecting the Board of Directors to the Shariah Board on the banks performance, using a Panel data which consisted of 32 Islamic banks during the period 2015-2018. The results show that meetings between the Board of Directors and the Shariah Board have a negative impact on the financial performance of Islamic banks. Through this research study, we aim to furnish new insights into the literature review of Islamic banks. Unlike previous researches, we use one new feature linking the Board of Directors to the Shariah Board. In addition, we employ a new measure to study the relationship between the Board of Directors and the Shariah Board, and its effect on the financial performance of banks.
Distinct Phenotype and Cytokine Signature Antigens in Breast Cancer Patients Have a Functional T Cell Responses to Tumor

The overall prevalence with which endogenous tumor Ags induce host T cell responses is unclear. Even when such responses are detected, they do not usually result in spontaneous remission of the cancer. We hypothesized that this might be associated with a predominant phenotype and/or cytokine proﬁle of tumor-speciﬁc responses that is different from protective T cell responses to other chronic Ags, such as CMV. We detected signiﬁcant T cell responses to CEA, HER-2/ neu , and/or MAGE-A3 in 17 of 21 breast cancer patients naive to immunotherapy. The pattern of T cell cytokines produced in response to tumor-associated Ags (TAAs) in breast cancer patients was signiﬁcantly different from that produced in response to CMV or inﬂuenza in the same patients. Speciﬁcally, there was a higher proportion of IL-2-producing CD8 (cid:1) T cells, and a lower proportion of IFN- (cid:2) -producing CD4 (cid:1) and/or CD8 (cid:1) T cells responding to TAAs compared with CMV or inﬂuenza Ags. Finally, the phenotype of TAA-responsive CD8 (cid:1) T cells in breast cancer patients was almost completely CD28 (cid:1) CD45RA (cid:3) (memory phenotype). CMV-responsive CD8 (cid:1) T cells in the same patients were broadly distributed among phenotypes, and contained a high proportion of terminal effector cells (CD27 (cid:3) CD28 (cid:3) CD45RA (cid:1) ) that were absent in the TAA responses. Taken together, these results suggest that TAA-responsive T cells are induced in breast cancer patients, but those T cells are phenotypically and functionally different from CMV- or inﬂuenza-responsive T cells. Immunotherapies directed against TAAs may need to alter these T cell signatures to be effective.
Isolation of the ARO] Cluster Gene of Saccharomyces cerevisiae

The AROJ cluster gene was isolated by complementation in Saccharomyces cerevisiae after transformation with a comprehensive yeast DNA library of BamHI restriction fragments inserted into the shuttle vector YEp13. Most of the transformants exhibited the expected episomal inheritance of the ARO+ phenotype; however, one stable transformant has been shown to be an integration of the AROJ fragment and the vector YEp13 at the arol locus. The insert containing AROJ is a 17.2-kilobase pair (kbp) BamHI fragment which complements both nonsense and missense alleles of arol. Subcloning by Sau3AI partial digestion further locates the AROJ segment to a 6.2-kbp region. An autonomously replicating sequence (ars) was found on the 17.2-kbp fragment. Yeast arol mutants transformed with the ARO1 episome express 5 to 12 times the normal level of the five AROJ enzyme activities and possess elevated amounts of the AROJ protein. The yeast AROI fragment also complemented aroA, aroB, aroD, and aroE mutants of Escherichia coli. The expression of AROI in both S. cerevisiae and E. coli was independent of the orientation of the fragment with respect to the vector. be due in part to negative comple- mentary effects between the plasmid AROJ-encoded and chromosomal arolE-encoded gene products. Alternatively, the various domains of the protein may be subject to differential inacti- vation by proteolytic cleavage in strains over-producing the enzyme. The integrative transfor- mant of the arolE strain carries one copy of AROJ and one copy of arolE. Intermediate levels of the AROJ activities are seen, presum-ably due to partially functional hybrid forms of the active dimer.
DIPLOMARBEIT Optical conductivity in the Falicov-Kimball model: a dual fermion perspective

The Falicov-Kimball model (FKM) is one of the simplest models to describe correlation effects in solid systems. It can be solved semi-analytically in dynamical mean field theory (DMFT), where all purely local correlations between electrons are taken into account and therefore within DMFT a good description of phenomena such as the metal-to-insulator transition is obtained. However, the charge density wave fluctuations that dominate the physics of the FKM and lead to a phase transition into an ordered state emerge from nonlocal correlations. To include such nonlocal correlations, diagrammatic extensions of DMFT have been developed recently. One of these methods, the dual fermion (DF) approach, is employed in this thesis to analyze the effect of nonlocal correlations. Especially, the effect of such nonlocal vertex corrections onto the optical conductivity – describing the interaction of light with the system – is investigated. It is shown that besides well-known phenomena, such as weak localization, a new form of bosonic optical excitations, coined π-tons, is prevalent in the FKM.
Vertical distribution of airborne bacterial communities in an Asian-dust downwind area, Vertical distribution of airborne bacteria

Bacterial populations transported from ground environments to the atmosphere get dispersed throughout downwind areas and can influence ecosystem dynamics, human health, and climate change. However, the vertical bacterial distribution in the free troposphere was rarely investigated in detail. We collected aerosols at altitudes of 3,000 m, 1,000 m, and 10 m over the Noto Peninsula, Japan, where the westerly winds carry aerosols from continental and marine areas. During the sampling period on March 10, 2012, the air mass at 3,000 m was transported from the Chinese desert region by the westerly winds, and a boundary layer was formed below 2,000 m. Pyrosequencing targeting 16S rRNA genes (16S rDNA) revealed that the bacterial community at 3,000 m was predominantly composed of terrestrial bacteria, such as Bacillus and Actinobacterium species. In contrast, those at 1,000 m and 10 m included marine bacteria belonging to the classes Cyanobacteria and Alphaproteobacteria. The entire 16S rDNA sequences in the clone libraries were identical to those of the terrestrial and marine bacterial species, which originated from the Chinese desert region and the Sea of Japan, respectively. The origins of air masses and meteorological conditions contribute to vertical variations in the bacterial communities in downwind atmosphere.
Study of reactor constitutive model and analysis of nuclear reactor kinetics by fractional calculus approach

The diffusion theory model of neutron transport plays a crucial role in reactor theory since it is simple enough to allow scientific insight, and it is sufficiently realistic to study many important design problems. The neutrons are here characterized by a single energy or speed, and the model allows preliminary design estimates. The mathematical methods used to analyze such a model are the same as those applied in more sophisticated methods such as multi-group diffusion theory, and transport theory. The neutron diffusion and point kinetic equations are most vital models of nuclear engineering which are included to countless studies and applications under neutron dynamics. By the help of neutron diffusion concept, we understand the complex behavior of average neutron motion. The simplest group diffusion problems involve only, one group of neutrons, which for simplicity, are assumed to be all thermal neutrons. A more accurate procedure, particularly for thermal reactors, is to split the neutrons into two groups; in which case thermal neutrons are included in one group called the thermal or slow group and all the other are included in fast group. The neutrons within each group are lumped together and their diffusion, scattering, absorption and other interactions are described in terms of suitably average diffusion coefficients and cross-sections, which are collectively known as group constants. We have applied Variational Iteration Method and Modified Decomposition Method to obtain the analytical approximate solution of the Neutron Diffusion Equation with fixed source. The analytical methods like Homotopy Analysis Method and Adomian Decomposition Method have been used to obtain the analytical approximate solutions of neutron diffusion equation for both finite cylinders and bare hemisphere. In addition to these, the boundary conditions like zero flux as well as extrapolated boundary conditions are investigated. The explicit solution for critical radius and flux distributions are also calculated. The solution obtained in explicit form which is suitable for computer programming and other purposes such as analysis of flux distribution in a square critical reactor. The Homotopy Analysis Method is a very powerful and efficient technique which yields analytical solutions. With the help of this method we can solve many functional equations such as ordinary, partial differential equations, integral equations and so many other equations. It does not require enough memory space in computer, free from rounding off errors and discretization of space variables. By using the excellence of these methods, we obtained the solutions which have been shown graphically.
