description: Energy densities of the quantum states that are superposition of two multi-electron-positron states are examined. It is shown that the energy densities can be negative only when two multi-particle states have the same number of electrons and positrons or when one state has one more electron-positron pair than the other. In the cases in which negative energy could arise, we find that the energy is that of a positive constant plus a propagating part which oscillates between positive and negative, and the energy can dip to negative at some places at for a certain period of time if the quantum states are properly manipulated. It is demonstrated that the negative energy densities satisfy the quantum inequality. Our results also reveal that for a given particle content, the detection of negative energy is an operation that depends on the frame where any measurement is to be performed. This suggests that the sign of energy density for a quantum state may be a coordinate-dependent quantity in quantum theory.

title: Ontogenetic Niche Shifts Within Floodplain Meadow Species
Creators: name: Cameron, Fiona
Publisher: name: The Open University
Year: 2014

description: Ontogenetic niche shifts, (ONSs), or changes in niche breadth or position during development, can be a critical component of effective target-species conservation, as long-term survival demands that the intergenerational requirements of species be fully met. However, although ONSs could occur in 80% of animal taxa, previous studies have rarely involved plants, and those that do exist have often been hampered by the lack of long-term, field-based data or appropriate measures. Analysis of the twenty years of botanical and hydrological data collated by the Floodplain Meadow Partnership, in combination with a multi-site, fully factorial planting experiment with two levels of competition, allows the following questions to be addressed; a) are ONSs occurring within floodplain meadow species, including the scarce Fritillaria meleagris, and how can the hydrological regime driving such shifts be quantified? b) Does flooding enhance recruitment within a range of meadow species? and, c) what are the mechanisms underlying flood-related gap creation? Results revealed that occurrence of ONSs varies according to species. Abundance of juvenile fritillaries was correlated with interquartile range in water-table depth prior to parental seed dispersal, suggesting micro-site limitation, with subsequent generations associated with predominantly dry conditions. Further differences in associate species and community membership of juveniles versus flowering adults were detected, which, results suggested, may be due to differential soil profile characteristics or other legacy effects. Seasonal as opposed to annually-derived hydrological variables were of particular relevance to the study of ONSs, and spring of the year before survey identified as the critical period for germination of all the selected species. Whereas flooding enhances recruitment and appears to drive ONSs within both Fritillaria meleagris and Leontodon autumnalis, germination of the obligate hemi-parasite Rhinonathus minor decreased in gaps lacking host species. A correlation between die-back of flood-sensitive grasses following flood-events and increased fritillary juvenile abundance was established.

description: We address factors which may influence the adoption of flow meters and/or certain irrigation scheduling practices. Measuring irrigation flow enhances management of irrigation, which improve profits. It also serves as a useful tool in evaluating which conservation measures for irrigation to adopt. This enhanced management can come in the form of scheduling. While less sophisticated versions of it exist, newer, more scientific forms can lead to better efficiency of irrigation events. As groundwater supplies become more limited, the use of flow meters and/or efficient scheduling techniques will allow farmers to better manage water resources.

description: This paper aims to investigate the role of market power on vertical integration choices in the Brazilian orange juice sector. The main hypothesis states that market power, along with economizing drivers, has had an important role in the economic organization of the orange juice sector. In order to accomplish this task, we examine the make-or-buy decision of juice-processing firms in procurement of inputs (fruits), through a 15-year panel of five firms (more than 90% of the market). Empirical results offer new theoretical insights on role of market power in vertical integration decision. From these theoretical advancements, as implications for practitioners, market power raises attention for critical strategizing issues and antitrust remedies.

description: Considering the opportunities offered by the Chinese beef market and the fragilities in the Sino-Brazilian beef trade supply chain, this study aims to identify the main sources and channels used by Brazilian beef packers to obtain information on the Chinese market. The results reveal that the Brazilian beef packers and institutions within the export sector have little knowledge regarding the Chinese market. Neither the size nor the export experience of the beef packing firms and the foreign direct investment seem to significantly influence the quality of the knowledge they hold on the Chinese beef market. The sector has neither an integrated database containing the essential information on the Chinese market nor a unified traceability system in place that could facilitate the information flow among the agents within the beef supply chain. Consequently, firms need to dedicate substantial management resources (time, financial and human) to collect information from various sources.

description: Improved maize seed is instrumental to deliver an Asian-style ‘green revolution’ for Africa. The paper reviews and makes a comparative analysis of the maize (corn) seed sector and its evolution in Kenya, Tanzania, Uganda and Ethiopia drawing from seed sector surveys and secondary data. Enhancing farmers’ access to and use of new maize varieties still presents a number of challenges in eastern Africa – not least due to a number of policy and institutional impediments to the development of the seed sector. The regional seed sectors also show some remarkable contrasts: they have evolved at different speeds and in different directions, driven by diverging agricultural growth opportunities and varying degrees of regulation, liberalization and restructuring. The paper reiterates calls for an enabling environment for private seed companies to evolve in order to serve the diverse farmer communities so that they benefit from existing and future improved maize seed opportunities.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions.

description: Thesis Artifacts for: A Showcase for the Titan Control Center A detailed description can be found in the README.md. The corresponding thesis can be found here. Abstract In times with an ever-increasing amount of generated data by Industrial Internet of Things sensors which needs to be collected and processed in near real-time. This leads to the need for an analytic platform with sophisticated software systems to process Big Data in near real-time. The Titan project is an example of a project which implements the Industrial DevOps approach to solve this challenge. Within the Titan platform, the Titan Control Center is a scalable architecture to analyze data streams in near real-time. This thesis aims to create a showcase for the Titan Control Center with a usability evaluation at the end. The showcase covers each key functionality of the Titan Control Center. The thesis starts with developing a new data generator to generate realistic measurements for the showcase. Additionally, we extend the Titan Control Center's current visualizations to provide the user with simple visualizations to gain the needed information from the monitored data quickly. After that, we conduct a usability evaluation of the system and discuss the results afterward.

description: The genus Hyponotum Wittmer, 1949
 The genus Hyponotum Wittmer, 1949 was erected as distinct from the genus Plectonotum in the reduced or absent pronotal bead, and in the simple pygidium, without apico-lateral protuberances. Wittmer designated Plectonotum albocinctum Pic, 1926 as the type species of Hyponotum, transferred P. grandicolle Pic, 1928, P. ruficolle Pic, 1926, P. violaceipenne Pic, 1928, and P. kuscheli Wittmer, 1945 to Hyponotum and described Hyponotum mimicum. Later Wittmer (1950, 1951, 1957, 1980) described eight new species belonging to this genus and transferred others from Plectonotum. Currently, it includes 21 species (Delkeskamp, 1977; Wittmer, 1980).
The genus has never benefited from any revision.The following key is a first attempt toward an identification key, based on types and other material preserved in the collections of Wittmer (NHMB), Pic (MNHN) and some personal ones.
This genus is not really homogeneous and the species can be separated into informal groups when a particular character is considered: a first group of species, already recognized by Wittmer, includes three species with a rough head surface, with wide areolar punctation; a group with a smooth and raised periphery of the pronotum; a group with modifications of the antennomeres of the males; other species with a lateral bead of the pronotum reduced to a small tuberosity of the anterior angles or without any bead. The distribution of this genus was known only from Chile and Argentina. Recent surveys bring to light two new species from central and north Peru, described below.

description: $\textbf{Object}$ Neuromuscular electrical stimulation (NMES)-induced isometric contraction is feasible during MRI and can be combined with acquisition of volumetric dynamic MR data, in a synchronous and controlled way. Since NMES is a potent resource for rehabilitation, MRI synchronized with NMES presents a valuable validation tool. Our aim was to show how minimal NMES-induced muscle contraction characterization, as evaluated through phase contrast MRI, differs between senior and young volunteers. $\textbf{Materials and Methods}$ Simultaneous NMES of the quadriceps muscle and phase contrast imaging were applied at 3T to 11 senior (75 $\pm$ 3 years) and 6 young volunteers (29 $\pm$ 7 years). A current sufficient to induce muscle twitch without knee extension was applied to both groups. $\textbf{Results}$ Strain vectors were extracted from the velocity fields and strain datasets were compared with non-parametric tests and descriptive statistics. Strain values were noticeably different between both groups at both current intensities and significant differences were observed in the regions of interest between the two electrodes. $\textbf{Discussion}$ In conclusion, NMES-synchronized MRI could be successfully applied in senior volunteers with strain results clearly different from the younger volunteers. Also, differences within the senior group were detected both in the magnitude of strain and in the position of maximum strain pixels.

title: CCD Modelling and Verification for ESA's Euclid CCD Architecture
Creators: name: Clarke, Andrew Stephen
Publisher: name: The Open University
Year: 2015

description: This thesis discusses semiconductor modelling carried out to investigate the charge packets which are present in Charge Coupled Devices (CCDs). The details of charge distribution are of interest for scientific CCDs, in particular those which may become damaged due to the effects of harsh radiation environments such as those experienced in space. Therefore this thesis focuses on the CCDs used in the main focal plane instrument (VIS, a visible imager) on the European Space Agency's Euclid space telescope due for launch in 2018. The thesis is spilt into two parts, with the early chapters concentrating on the development of device models and the interpretation of modelling results. The modelling work is verified in latter chapters to ensure that the model predictions concur with lab based measurements on test devices. Model verification makes up a large part of this thesis, ensuring the accuracy of the models. In some cases initial modelling work was shown to predict parameters different to those measured in test devices, however, investigations are made which show manufacturing errors are partly to blame. During this work images were taken using a Focussed Ion Beam Scanning Electron Microscope (FIBSEM), which allows cross-sectional images of the device to be taken, these showed deviations from the designed ploy silicon electrode geometry, resulting in some undersized and some oversized gates, these reduced the accuracy of some models, which were later modified. Through this investigation a method for predicting gate geometry was developed based on the Silvaco device models. Further testing was carried out to verify the charge packet relationship with CTE in test devices. CTE is measured using the Extended Pixel Edge Response (EPER) technique, which allows CTE to be measured over a range of signal sizes. The CTE data can be used to calculate the charge loss per pixel as an average across the device column and these values can be compared against the charge packet volume simulations.

description: Transport through semiconductor nanostructures is a quantum-coherent process. This paper focuses on systems in which the electron's dynamics is ballistic and the transport is dominated by the scattering from structure boundaries. Opposite to the well-known case of the nuclear reactions, the potentials defining semiconductor structures are nonspherically symmetric and the asymptotic motion of the electrons is determined by the different potential levels in the contacts. For this special type of potential the mathematical foundations for the scattering theoretical description of the transport phenomena are presented. The transport properties of the system are then derived from the scattering matrix using the Landauer-Buttiker formalism. A rigorous analysis of the analytical properties of the S matrix leads to the most general resonant line shape described by a Fano function with a complex asymmetry parameter. On this basis the resonant and nonresonant contributions to the conductance and capacitance of the system are identified.

Molecular Gas in Candidate Double Barred Galaxies III. A Lack of Molecular Gas?

Publisher: name: arXiv
Year: 2004
Subjects: subject: Astrophysics (astro-ph)

description: Most models of double-barred galaxies suggest that a molecular gas component is crucial for maintaining long-lived nuclear bars. We have undertaken a CO survey in an attempt to determine the gas content of these systems and to locate double barred galaxies with strong CO emission that could be candidates for high resolution mapping. We observed 10 galaxies in CO J=2-1 and J=3-2 and did not detect any galaxies that had not already been detected in previous CO surveys. We preferentially detect emission from galaxies containing some form of nuclear activity. Simulations of these galaxies require that they contain 2% to 10% gas by mass in order to maintain long-lived nuclear bars. The fluxes for the galaxies for which we have detections suggest that the gas mass fraction is in agreement with these models requirements. The lack of emission in the other galaxies suggests that they contain as little as 7 x 10^6 solar masses of molecular material which corresponds to < 0.1% gas by mass. This result combined with the wide variety of CO distributions observed in double barred galaxies suggests the need for models of double-barred galaxies that do not require a large, well ordered molecular gas component.

description: To improve the usability of a revision history, change untangling, which reconstructs the history to ensure that changes in each commit belong to one intentional task, is important. Although there are several untangling approaches based on the clustering of fine-grained editing operations of source code, they often produce unsuitable result for a developer, and manual tailoring of the result is necessary. In this paper, we propose ChangeBeadsThreader (CBT), an interactive environment for splitting and merging change clusters to support the manual tailoring of untangled changes. CBT provides two features: 1) a two-dimensional space where fine-grained change history is visualized to help users find the clusters to be merged and 2) an augmented diff view that enables users to confirm the consistency of the changes in a specific cluster for finding those to be split. These features allow users to easily tailor automatically untangled changes.

description: This is the fifth In Brief in a series presenting findings from a multi-year study of sorcery accusation-related violence (SARV) in Papua New Guinea (PNG). In 2017, the first In Brief of the series described the two main quantitative data collection methods used in the project to estimate the extent of the SARV issue: a SARV Incident Database for four hotspot provinces over a four-and-a-half-year period (January 20161–June 2020) and a national incident and court case dataset (media dataset) over a 24-year period (1996–June 2020). The integration of these quantitative datasets with the qualitative data is described here (Losoncz et al. 2020). In Briefs 2–4 reported on findings from quantitative analysis of media and case law from 1996–2016. This In Brief and In Briefs 6 and 7 report select further findings from the SARV Incident Database.

description: Differential rotation in stars generates toroidal magnetic fields whenever an initial seed poloidal field is present. The resulting magnetic stresses, along with viscosity, drive the star toward uniform rotation. This magnetic braking has important dynamical consequences in many astrophysical contexts. For example, merging binary neutron stars can form "hypermassive" remnants supported against collapse by differential rotation. The removal of this support by magnetic braking induces radial fluid motion, which can lead to delayed collapse of the remnant to a black hole. We explore the effects of magnetic braking and viscosity on the structure of a differentially rotating, compressible star, generalizing our earlier calculations for incompressible configurations. The star is idealized as a differentially rotating, infinite cylinder supported initially by a polytropic equation of state. The gas is assumed to be infinitely conducting and our calculations are performed in Newtonian gravitation. Though highly idealized, our model allows for the incorporation of magnetic fields, viscosity, compressibility, and shocks with minimal computational resources in a 1+1 dimensional Lagrangian MHD code. Our evolution calculations show that magnetic braking can lead to significant structural changes in a star, including quasistatic contraction of the core and ejection of matter in the outermost regions to form a wind or an ambient disk. These calculations serve as a prelude and a guide to more realistic MHD simulations in full 3+1 general relativity.

description: This article is devoted to the application of the holographic principle to describe Rip brane cosmological models in the presence of a bulk viscosity. We make use of the generalized infrared-cutoff holographic dark energy, introduced by Nojiri and Odintsov We consider various examples: Rip brane cosmology corresponding to the Little Rip case, asymptotic de Sitter theory, and the so-called Big Freeze theory leading to a singularity. Analytical expressions for infrared cutoffs, as well as the particle and the future horizons at the brane, are obtained. The equations for energy conservation on the brane within the holographic theory are obtained in each case. The correspondence between viscous cosmology and holographic cosmology on the brane is shown.

title: Characterizing RNA Targets of TDP-43

description: TAR-DNA-binding 43kDa protein (TDP-43), is an RNA binding protein that has been linked to the pathology of neurodegenerative diseases such as ALS and FTLD. However, pathological mechanisms involving TDP-43, remain elusive. Current hypotheses have converged on altered RNA processing, due to a loss of function of TDP-43. To gain better insight into the pathogenic mechanisms linked to TDP-43, we hypothesised that a loss of function may lead to alterations in splicing and/or changes in protein expression in transcripts potentially linked to neurodegeneration. Thus, 2-dimensional electrophoresis (2-DE) gels and splice-junction microarrays were utilised to identify targets of TDP-43 whose expression exhibited association with altered TDP-43 levels. The 2-DE analyses depicted changes in several proteins (spots), which, upon subsequent validation, did not reveal any correlations with differential spot intensities. In contrast, the splice-junction arrays identified TDP-43 dependent changes in 2371 genes from which candidate genes for validation were selected upon fulfilment of criteria for being altered when TDP-43 was depleted and reversible by overexpression of wild type TDP-43, but not with mutant (F4L) TDP-43. 162 genes were selected and further narrowed down based on a two-fold or higher splicing score. RT-PCR validation confirmed 6/19 transcripts, POLDIP3, BCL2L11, MADD, STAG2, BRD8 and FNIP1, as undergoing TDP-43 dependent splicing. Protein level alterations, were also observed in MADD and STAG2, following which, TDP-43 binding sites were mapped. Lastly, using an inducible TDP-43 aggregation model, a loss of function effect for TDP-43 was recapitulated i. e. similar changes in splicing profiles as when TDP-43 was knocked down, for all six of the above genes, thus, supporting a loss of function hypothesis in TDP-43 aggregates. Our results further contribute to the number of genes known to be affected by TDP-43, with the distinct observation of involvement in apoptotic and mitotic pathways, which may have implications for TDP-43 proteinopathies.

description: We give a new proof that compact infra-solvmanifolds with isomorphic fundamental groups are smoothly diffeomorphic. More generally, we prove rigidity results for manifolds which are constructed using affine actions of virtually polycyclic groups on solvable Lie groups. Our results are derived from rigidity properties of subgroups in solvable linear algebraic groups.

description: Mostly multiband photometric transit observations have been used so far to retrieve broadband transmission spectra of transiting exoplanets in order to study their atmosphere. An alternative method has been proposed and has only been used once to recover transmission spectra using chromatic Rossiter-McLaughlin observations. Stellar activity has been shown to potentially imitate narrow and broadband features in the transmission spectra retrieved from multiband photometric observations; however, there has been no study regarding the influence of stellar activity on the retrieved transmission spectra through chromatic Rossiter-McLaughlin. In this study with the modified SOAP3.0 tool, we consider different types of stellar activity features (spots and plages), and we generated a large number of realistic chromatic Rossiter-McLaughlin curves for different types of planets and stars. We were then able to retrieve their transmission spectra to evaluate the impact of stellar activity on them. We find that chromatic Rossiter-McLaughlin observations are also not immune to stellar activity, which can mimic broadband features, such as Rayleigh scattering slope, in their retrieved transmission spectra. We also find that the influence is independent of the planet radius, orbital orientations, orbital period, and stellar rotation rate. However, more general simulations demonstrate that the probability of mimicking strong broadband features is lower than 25% and that can be mitigated by combining several Rossiter-McLaughlin observations obtained during several transits.

We prove that each unit-distance preserving mapping f:C^2->C^2 has a form J circ (gamma,gamma), where gamma:C->C is a field homomorphism and J:C^2->C^2 is an affine mapping with orthogonal linear part. We also prove a more general result for any commutative field K for which {x \in K: x^2+1=0} \neq \emptyset and char(K) \not\in {2,3,5}.

description: The study evaluates the impact of risk on enterprises of male, female and young farmers operating in the formal and informal smallholder dairy value chains in Tanzania. It also examines the effect of uncertainty on the decision to invest in milk production in the two value chains. Results indicate that youths in the informal dairy value chain face the greatest level of risk followed by men in the formal value chain, and then men in the informal value chain. Women in both value chains and youths in the formal value chain face relatively low risk. Overall, milk production in the informal value chain is found to be substantially riskier than production in the formal chain. Optimal investment triggers are found to be much larger than the conventional triggers and are sensitive to volatility of returns. The results’ managerial and policy implications for inclusive dairy industry development in Tanzania are highlighted.

description: This is the sixth In Brief on the findings from a quantitative analysis of sorcery accusation-related violence (SARV) in Papua New Guinea (PNG). We report on an incident database of recorded SARV cases (including incidents of accusation with no physical violence and those that involved violence) in four provinces over a four-and-a-half year period (January 20161–June 2020). Here, we reflect on what we have learnt about the factors that catalyse accusations of sorcery and consider which factors are salient in causing accusations to turn into violence. We consider three dimensions of the landscape in which the potential of SARV is situated: 1. Conducive structural factors — essential or conducive structural factors relevant to the development of SARV; 2. Proximate factors — shorter term, localised factors that provide the enabling environment; and 3. Trigger events that are closely connected with actual accusation.

description: As multicellular organisms grow, spatial and temporal patterns of gene expression are strictly regulated to ensure that developmental programs are invoked at appropriate stages. In this work, we describe a putative transcriptional regulator in Arabidopsis, TACO LEAF (TCO), whose overexpression results in the ectopic activation of reproductive genes during vegetative growth. Isolated as an activation-tagged allele, tco-1D displays gene misexpression and phenotypic abnormalities, such as curled leaves and early flowering, characteristic of chromatin regulatory mutants. A role for TCO in this mode of transcriptional regulation is further supported by the subnuclear accumulation patterns of TCO protein and genetic interactions between tco-1D and chromatin modifier mutants. The endogenous expression pattern of TCO and gene misregulation in tco loss-of-function mutants indicate that this factor is involved in seed development. We also demonstrate that specific serine residues of TCO protein are targeted by the ubiquitous kinase CK2. Collectively, these results identify TCO as a novel regulator of gene expression whose activity is likely influenced by phosphorylation, as is the case with many chromatin regulators.
