strukturelle Finanzlage der Länder
Ländervergleiche
Niedrigzinsphase

description: Seit Einführung der neuen Schuldenregel hat sich die Finanzlage der deutschen Bundesländer deutlich verbessert. Nach unseren Berechnungen mit dem Aggregierten Quotierungsverfahren konnten die meisten Länder ihre strukturellen Budgetdefizite abbauen und im Jahr 2017 schon 14 Länder strukturelle Budgetüberschüsse erzielen; lediglich das Saarland und Nordrhein‐ Westfalen wiesen strukturelle Defizite auf. Die „strukturelle“ Besserung überzeichnet indes die Konsolidierungsfortschritte, denn sie ist zum großen Teil dem historisch niedrigen Zinsniveau zu verdanken, das zu erheblichen Einsparungen beim Schuldendienst führte. Da die Finanzierungskonditionen aber nicht dauerhaft so günstig bleiben wie in den vergangenen Jahren, verdecken die Zinsersparnisse den bei vielen Ländern noch bestehenden Konsolidierungsbedarf. Wir plädieren daher dafür, nur nachhaltige Einsparungen bei den Zinslasten als strukturelle Besserung zu klassifizieren und entwickeln ein Bereinigungsverfahren, das neben den Konjunktureinflüssen auch die Verzerrung durch das äußerst niedrige Zinsniveau beachtet. Unsere Simulationen zeigen, dass nach einer Bereinigung um die nicht nachhaltigen Einsparungen beim Schuldendienst nicht mehr 14, sondern nur neun Länder im Jahr 2017 einen strukturell mindestens ausgeglichenen Haushalt erzielt haben. Bei den verbleibenden sieben Ländern besteht teilweise noch erheblicher Konsolidierungsbedarf. Wir zeigen darüber hinaus, dass die zur quantitativen Vergleichbarkeit der Länderfinanzen in der Regel verwandten Einwohner‐Indikatoren wesentliche Strukturunterschiede zwischen den Ländern unberücksichtigt lassen und damit zu irreführenden Schlussfolgerungen führen können. Wir empfehlen daher, bei Ländervergleichen Kennzahlen zu verwenden, die strukturelle Unterschiede zwischen den Ländern bei Erwerbstätigkeit und Produktivität beachten.

description: We propose a fully automated algorithm based on a deep learning framework enabling screening of a coronary computed tomography angiography (CCTA) examination for confident detection of the presence or absence of coronary artery atherosclerosis. The system starts with extracting the coronary arteries and their branches from CCTA datasets and representing them with multi-planar reformatted volumes; pre-processing and augmentation techniques are then applied to increase the robustness and generalization ability of the system. A 3-dimensional convolutional neural network (3D-CNN) is utilized to model pathological changes (e.g., atherosclerotic plaques) in coronary vessels. The system learns the discriminatory features between vessels with and without atherosclerosis. The discriminative features at the final convolutional layer are visualized with a saliency map approach to provide visual clues related to atherosclerosis likelihood and location. We have evaluated the system on a reference dataset representing247 patients with atherosclerosis and 246 patients free of atherosclerosis. With five-fold cross-validation,an Accuracy = 90.9%, Positive Predictive Value = 58.8%, Sensitivity = 68.9%, Specificity of 93.6%, and Negative Predictive Value (NPV) = 96.1% are achieved at the artery/branch level with threshold 0.5. The average area under the receiver operating characteristic curve is 0.91. The system indicates a high NPV, which may be potentially useful for assisting interpreting physicians in excluding coronary atherosclerosis in patients with acute chest pain.
Development of a novel uncovered stent system for the management of complex aortic aneurysms

description: Endovascular aortic repair (EVAR) is a minimally invasive alternative to open surgery for the treatment of aortic aneurysms (AA). However, standard EVAR is not applicable to complex AA with involvement of vital branches, which could be occluded by the endograft. As an emerging technique, the concept of multiple overlapping uncovered stents (MOUS) have been proposed to manage complex lesions. MOUS was used to modulate the flow pattern inside the aneurysm sac, and promote the thrombus formation followed by the aneurysm shrinkage. In this dissertation, we sought to investigate the mechanism of MOUS-induced flow modulation and key factors associated with the success of this novel technique: - The mechanical behaviour of AA was characterised by uniaxial material tests (Chapter 4). A Bayesian framework was proposed for material constants identification. They were found correlated to the microstructure of tissue fibre network and were capable in differentiating tissue types. - Solid-to-solid interaction and one-way fluid-solid interaction (FSI) analysis was performed based on patient-specific computer tomography angiography (Chapters 5&6). Structural stress concentrations were observed within the landing zones, which increased with the number of stents deployed. In the parameter studies (Chapter 6), the overall porosity was identified as the dominant factor of the flow-diverting outcome, while cross-stent structures of MOUS had limited influence. - The pathological effect of structural stress concentration induced by an implanted device was further studied in rabbit models (Chapter 7). The wall structural stress and fluid shear stress were obtained from FSI analysis based on magnetic resonance imaging (MRI), and correlated to plaque characteristics. Both high structural stress and low fluid shear stress were found correlated to plaque initialisation and increased inflammation. Overall, MOUS modulates the blood flow with robust performance under different overlapping patterns. Image-based biomechanical analysis can optimise MOUS design and can contribute to personalised pre-surgery planning.

description: In this paper, we set up a theoretical model to study how unilateral policies aimed at improving transparency for consumers concerning the source of certain raw materials influence prices, illegal mining activities and welfare. The model distinguishes two regions in the world, North and South. Firms in the North import natural resources from the South to produce final consumption goods. In one of the countries, in the South, local groups attempt to access natural resources, which results in rent seeking conflicts with the government and illegal mining. We find that a unilateral embargo against the conflict country as well as certification of legal mines can reduce rent seeking and illegal mining with different welfare consequences in the countries involved.

description: The main protease of SARS-CoV-2 is one of the important targets to design and develop antiviral drugs. In this study, we have selected 40 antiviral phytochemicals to find out the best candidates which can act as potent inhibitors against the main protease. Molecular docking is performed using AutoDock Vina and GOLD suite to determine the binding affinities and interactions between the phytochemicals and the main protease. The selected candidates strongly interact with the key Cys145 and His41 residues. To validate the docking interactions, 100 ns molecular dynamics (MD) simulations on the five top-ranked inhibitors including hypericin, cyanidin 3-glucoside, baicalin, glabridin, and α-ketoamide-11r are performed. Principal component analysis (PCA) on the MD simulation discloses that baicalin, cyanidin 3-glucoside, and α-ketoamide-11r have structural similarity with the apo-form of the main protease. These findings are also strongly supported by root-mean-square deviation (RMSD), root-mean-square fluctuation (RMSF), radius of gyration (Rg), and solvent accessible surface area (SASA) investigations. PCA is also used to find out the quantitative structure-activity relationship (QSAR) for pattern recognition of the best ligands. Multiple linear regression (MLR) of QSAR reveals the R2 value of 0.842 for the training set and 0.753 for the test set. Our proposed MLR model can predict the favorable binding energy compared with the binding energy detected from molecular docking. ADMET analysis demonstrates that these candidates appear to be safer inhibitors. Our comprehensive computational and statistical analysis show that these selected phytochemicals can be used as potential inhibitors against the SARS-CoV-2. Communicated by Ramaswamy H. Sarma

description: In this paper, we compare three different models, namely the Nelson- Siegel model, the Svensson model and the Diebold- Li model, for the estimation of an intraday yield curve on the Italian interbank credit market e-MID. Using a sample which spans from October 2005 until March 2010, the first important finding is that all three models are highly suitable for the estimation of an intraday yield curve providing superior empirical results when compared with similar works on e-MID. The second important finding is that, based on different in sample statistics, the Svensson model dominates the other two models before, during and after the financial crisis from 2007. Moreover, the Nelson- Siegel model seems to dominate the Diebold- Li model although these differences in goodness-of-fit between these two models may not be statistically significant.
Doctrinal Controversy and the Church Economy of Post-Chalcedon Palestine

description: The Fourth Ecumenical Council, held at Chalcedon in 451, began a period of extraordinary social and political crisis across the Eastern Mediterranean. In Palestine, as elsewhere, the centuries that followed were characterised by internecine conflict between local Christians, persisting until the collapse of Roman authority in the region during the reign of the emperor Heraclius. Since Edward Gibbon, historians have struggled to contextualise this debate, ostensibly an argument between proponents of rival, but also substantially identical, Christologies. This thesis considers what role socio-economic factors may have played in shaping contemporary accounts of the Council’s fraught reception. It asks whether this may have distorted our understanding of a defining Late Antique debate. Chalcedon’s reforms had wide-reaching consequences, not only for the Empire’s official Christological policy, but for the broader structure of the ‘Church economy,’ the systems through which Christian institutions were financed and maintained, referred to at length in the Council’s disciplinary canons. Its rulings held particular significance for Palestine in its status as the Christian ‘Holy Land.’ Here I explore this facet of Chalcedon’s legacy, whilst considering how the language of doctrinal controversy generated by the Council served to frame episodes of material competition between rival communities of clerics and monks. The thesis offers a new reading of the texts produced by key actors in these confrontations, many of which have been historically neglected. It follows in the wake of recent attempts to analyse other religious conflicts of this period in light of contemporary social or political conditions, or through reference to ‘networks’ of influence and patronage. I apply this methodology to the study of the Palestinian partisans in the antagonism which followed Chalcedon, whilst also drawing upon the archaeologically-grounded study of material culture which has influenced so many other areas of early medieval history.

description: Visual Odometry (VO) accumulates a positional drift in long-term robot navigation tasks. Although Convolutional Neural Networks (CNNs) improve VO in various aspects, VO still suffers from moving obstacles, discontinuous observation of features, and poor textures or visual information. While recent approaches estimate a 6DoF pose either directly from (a series of) images or by merging depth maps with optical flow (OF), research that combines absolute pose regression with OF is limited. We propose ViPR, a novel modular architecture for long-term 6DoF VO that leverages temporal information and synergies between absolute pose estimates (from PoseNet-like modules) and relative pose estimates (from FlowNet-based modules) by combining both through recurrent layers. Experiments on known datasets and on our own Industry dataset show that our modular design outperforms state of the art in long-term navigation tasks.

Dirac's equation in 1+1 D from a random walk

Year: 2001
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: This paper is an investigation of the class of real classical Markov processes without a birth process that will generate the Dirac equation in 1+1 dimensions. The Markov process is assumed to evolve in an extra (ordinal) time dimension. The derivation requires that occupation by the Dirac particle of a space-time lattice site is encoded in a 4 state classical probability vector. Disregarding the state occupancy, the resulting Markov process is a homogeneous and almost isotropic binary random walk in Dirac space and Dirac time (including Dirac time reversals). It then emerges that the Dirac wavefunction can be identified with a polarization induced by the walk on the Dirac space-time lattice. The model predicts that QM observation must happen in ordinal time, and that wavefunction collapse is due not to a dynamical discontinuity, but to selection of a particular ordinal time. Consequently, the model is more relativistically equitable in its treatment of space and time in that the observer is attributed no special ability to specify the Dirac time of observation.

The history of star formation in a LCDM universe

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Employing hydrodynamic simulations of structure formation in a LCDM cosmology, we study the history of cosmic star formation from the "dark ages" at redshift z~20 to the present. In addition to gravity and ordinary hydrodynamics, our model includes radiative heating and cooling of gas, star formation, supernova feedback, and galactic winds. By making use of a comprehensive set of simulations on interlocking scales and epochs, we demonstrate numerical convergence of our results on all relevant halo mass scales, ranging from 10^8 to 10^15 Msun/h. The predicted density of cosmic star formation is broadly consistent with measurements, given observational uncertainty. From the present epoch, it gradually rises by about a factor of ten to a peak at z~5-6, which is beyond the redshift range where it has been estimated observationally. 50% of the stars are predicted to have formed by redshift z~2.1, and are thus older than 10.4 Gyr, while only 25% form at redshifts lower than z~1. The mean age of all stars at the present is about 9 Gyr. Our model predicts a total stellar density at z=0 of Omega_*=0.004, corresponding to about 10% of all baryons being locked up in long-lived stars, in agreement with recent determinations of the luminosity density of the Universe. We determine the "multiplicity function of cosmic star formation" as a function of redshift; i.e. the distribution of star formation with respect to halo mass. We also briefly examine possible implications of our predicted star formation history for reionisation of hydrogen in the Universe. We find that the star formation rate predicted by the simulations is sufficient to account for hydrogen reionisation by z~6, but only if a high escape fraction close to unity is assumed. (abridged)

description: It is known that a real symmetric circulant matrix with diagonal entries $d\geq0$, off-diagonal entries $\pm1$ and orthogonal rows exists only of order $2d+2$ (and trivially of order $1$) [Turek and Goyeneche 2019]. In this paper we consider a complex Hermitian analogy of those matrices. That is, we study the existence and construction of Hermitian circulant matrices having orthogonal rows, diagonal entries $d\geq0$ and any complex entries of absolute value $1$ off the diagonal. As a particular case, we consider matrices whose off-diagonal entries are 4th roots of unity; we prove that the order of any such matrix with $d$ different from an odd integer is $n=2d+2$. We also discuss a similar problem for symmetric circulant matrices defined over finite rings $\mathbb{Z}_m$. As an application of our results, we show a close connection to mutually unbiased bases, an important open problem in quantum information theory.

description: The purpose of this study is to reveal how investments in agricultural development and food security would safeguard the Caribbean from future global crisis. History shows that agriculture was the key development that led to the rise of civilization across the world and was the main contributor to the Caribbean economy before the 1950‟s. However, agricultural activity declined subsequent to the emergence of tourism and financial services sectors throughout the Region. Then in the 1990‟s, the situation became progressively worse as the North American Free Trade Agreement (NAFTA) was implemented and the decline of the banana industry resulted. Despite these setbacks, an opportunity to reconsider the validity of this sector would become evident in 2007 and 2008, as food shortages developed worldwide and a global financial crisis was declared. These events created two options for the Caribbean: either to react to the present global climate ad-hoc or to be pro-active in approach, with the intention (i) to alleviate poverty on national levels, (ii) to advance economic development and trade across the Region and (iii) to make sustainable development more attainable for the Caribbean, as a whole. Naturally, this research supports the pro-active approach. To do this, agricultural development and food security must become the focal point of the Caribbean economies. Accordingly, the paper recommends that investment within the agricultural sector be undertaken more aggressively across the Region. The research uses the mixed research approach method to validate its claim.

description: The multiwavelength emission spectrum and associated velocity field of the Seyfert prototype NGC 4151 is modeled. HST data has impressively revealed the existence of a large range of velocities (100 - 1500 \kms) dominating the emitting clouds in the extended emission line region of the galaxy. Following this observational result, a revision of the photoionization modeling approach applied to NGC 4151 is presented. It is concluded that a mixture of radiation dominated clouds and shock dominated clouds are required to explain the multiwavelength line and continuum spectra of the galaxy.

description: Through the application of the technological solution of the “extended vehicle” con-cept the car manufacturers can capture exclusive control of the data of connected cars lead-ing to serious concerns about negative effects on competition, innovation and consumer choice on the markets for aftermarket and other complementary services in the ecosystem of connected and automated driving. Therefore a controversial policy discussion has emerged in the EU about access to in-vehicle data and the connected car for independent service pro-viders in the automotive industry. This paper claims that this problem should be seen as part of the general question of the optimal governance of data in the ecosystem of connected and automated mobility. The paper offers an overview about this policy discussion and analyzes this problem from an economic perspective by using a market failure analysis. Besides com-petition problems (esp. on markets for aftermarket and other services in the connected car) also market failures in regard to technological choice (extended vehicle vs. interoperable on-board application platform) and information and privacy problems (“notice and consent” solu-tions) can emerge, leading to the question of appropriate regulatory solutions. The paper discusses solutions through data portability, data rights, competition law, and recommends a sector-specific regulatory approach.

description: This thesis studies the determinants and outcomes of the skill systems in Mexico and Turkey, two crucial cases of middle-income countries (MICs). Despite the similarities in their previous institutional environments and links to the global economy, Turkey has experienced higher economic growth and better social development compared to Mexico. This PhD project focuses on the Mexican and Turkish skill systems, which have been significant institutions that affect the (different) economic and social characteristics of advanced industrialised countries in the literature on comparative capitalisms (CCs). This study builds its theoretical approach on the arguments of CCs literature and the claims of globalisation, where it draws from the studies on global value chains (GVCs). It scrutinises the patterns of convergence due to globalisation and ongoing divergence because of the variation of institutional structures. It examines the complementarities and outcomes of the skill systems, which will then help to understand the divergence of development experiences between Mexico and Turkey. This PhD project carries out a multi-level research and focuses the empirical study on auto parts-automotive value chains (AACs), which is an important industry for many MICs including Mexico and Turkey. The multi-level research first includes a macro-level study of local institutions in Mexico and Turkey, as well as the convergence patterns through the AACs. This is complemented with a micro-level analysis of firms’ strategies to find workers with technical skills in production functions. The findings show that while there is some convergence in the Mexican and Turkish auto parts producers’ skill needs, firms from these two countries adopt different strategies to address their needs. The distinctive national institutions in Mexico and Turkey, which are shaped by the differences in the state’s involvement, are the main reasons for this divergence. The differences between the Mexican and Turkish skill systems have created different outcomes for both the firms and workers in these countries, and hence are expected to have contributed to their diverging development paths.

We found the pumped currents can have symmetries $I(B,ϕ) = -I(-B,-ϕ)$ and $I(B,ϕ) = I(-B,-ϕ)$, where $ϕ$ is the phase difference of two time dependent perturbations, depending on the discrete symmetry considered. The results in the adiabatic limit for each discrete symmetry are compared with those of Brouwer's formula.

Self-motivated voluntary environmental protection

logit

description: The core questions of this paper are: What are the determinants for the provisions of some public goods like environmental protection work by citizens and how can this work be delegated to the citizens? On the basis of a survey's micro data, we show which motives are relevant to the choice between a public award with no monetary value and a symbolic payment of €10. For these purposes, we apply the binary choice models. The results reveal several significant impacts where the age as continuous variable shows a stable quadratic-like shape with firstly decreasing and then increasing vigilance for moneyless participation in environmental protection regarding the age of a person. The intrinsic motivation itself seems to be another crucial positive factor. For example, the higher planed hypothetic free time measured in hypothetic hours for environmental protection, the higher the probability that this individual indeed would do it. Moreover, the one's reputation may influence positively the honorary contribution to environmental protection. On the other hand, the probability for an active honorary environmental protection is smaller by young people in training and in absence of social situations. Interestingly, we found that the gender plays no significant role in this context. Hence, we can provide an elaboration of an incentive system for environmental commitment of Kassel's citizens which can be a base for further regional economic policy in this context.

description: Eukaryotic genomes contain a large number of pyrimidine-purine rich regions and such regions can assume varied DNA conformations, including triple-stranded structures. These structures have fascinated scientists because of their considerable therapeutic applications. These structures have also profound implications in the field of nanotechnology as they can be used to develop DNA-based nanostructures and materials. Therefore, for any application, it is important to understand the formation of triplex structures, both in quantitative and qualitative terms. A combination of gel electrophoresis, UV-thermal denaturation and circular dichroism (CD) spectroscopy was used to investigate the formation of inter- as well as intramolecular triplex, in pyrimidine motif at BOLF1 gene of human herpesvirus 4 (HH4) genome. This gene codes for inner tegument protein, which plays crucial roles in viral replication. The said oligopurine•oligopyrimidine duplex was targeted via a designed triple helix forming oligopyrimidine nucleotide (TFO) in intermolecular as well as intramolecular fashion. Our studies revealed that intramolecular triplex formation takes place at acidic as well as at neutral pH; whereas low pH is required for its intermolecular version. This comparative study between inter- and intramolecular triplex allowed us to demonstrate that intramolecular structure is more stable to its intermolecular counterpart. Numerous models for mono-, bi- and trimolecular structures adopted by these DNA sequences have been suggested. This report adds to our existing knowledge about DNA triple helical structures.

sustainable forest manage- ment

description: In this paper, I study the effectiveness of privately managed FSC certified forests and public sustainability reserves distributed over the entire Brazilian Amazon from 2002-2015. The paper uses high-resolution data on forest cover derived from satellite images and organized in a grid of 1 km2 cells. Using a difference-in-differences estimator in a regression discontinuity environment, I find an increase in deforestation of an annual area of 8,057 ha in FSC forests after the certification. Public sustainability zones' impact on deforestation is also positive but declines over time. The effectiveness of both type of zones improves if they are located closer to (ex- port) markets or existing infrastructure.

description: Using an event-study design, we investigate monetary policy interest-rate-to-performance sensitivity of the European banking sector over the 07/2012–06/2017 period when interest rates were (close to) zero. We apply the Wordscores approach to introductory statements of ECB's Governing Council press conferences to estimate a ‘shadow prime rate’. Based on short-run intraday event windows, we find shadow prime rate changes positively affect changes in the EURO-STOXX-Banks Future. Our findings add to the recent evidence docu-menting that banks benefit from increasing interest rate levels in a low-interest-rate envi-ronment.

description: Meiotic recombination promotes genetic variation by reciprocal exchange of genetic material producing novel allelic combinations that influence important agronomic traits in crop plants. Therefore, harnessing meiotic recombination has the potential to accelerate crop improvement via classical breeding. Numerous genes involved in crossover formation have been identified in model systems. For example, SPO11 mediates generation of meiotic DNA double-strand breaks (DSBs) across all eukaryotes, which may be repaired as crossovers. However, downstream regulators of recombination remain to be identified, including those with species-specific roles. To isolate crossover frequency modifiers I performed a high-throughput forward genetic screen using EMS mutagenesis of Arabidopsis carrying a fluorescent crossover reporter line called 420. The primary screen isolated nine mutants from ~3,000 scored individuals that showed significantly higher (high crossover rate, hcr) or lower (low crossover rate, lcr) crossover frequency, including a new fancm allele. Four mutants (hcr1, hcr2, hcr3 and lcr1) were mapped by sequencing and candidate genes identified. The hcr1 mutation was confirmed as being located within the PROTEIN PHOSPHATASE X-1 (PPX-1) gene, using isolation of an independent allele and complementation studies. Similarly, the lcr1 mutation was confirmed to be within the gene TBP-ASSOCIATED FACTOR 4B (TAF4B). Using immunocytological staining I observed that hcr1 did not show changes in DSB-associated foci (RAD51), but it did show a significant increase in crossover-associated MLH1 foci. The hcr1 mutation increases crossovers mainly in the sub-telomeric chromosome regions, which remain sensitive to crossover interference. Also the genetic interaction between the hcr1 and fancm mutations is additive. These results support a model where PPX- 1 acts to limit recombination via the Class I interfering CO pathway, downstream of DSB formation. In summary, this genetic screen has led to discovery of novel genes that regulate meiotic recombination and their functional characterization may find utility in crop breeding programs.

description: A30 belongs to a class of planetary nebulae identified as "born-again", containing dense, hydrogen-poor ejecta with extreme abundance discrepancy factors (ADFs), likely associated with a central binary system. We present intermediate-dispersion spectroscopy of one such feature-the J4 equatorial knot. We confirm the apparent physical and chemical segregation of the polar and equatorial knots observed in previous studies, and place an upper limit on the ADF for O$^{2+}$ of 35, significantly lower than that of the polar knots. These findings further reinforce the theory that the equatorial and polar knots originate from different events.

Strain-promoted azide-alkyne cycloaddition
Bioorthogonal chemistry

description: Protein-protein interactions (PPIs) are responsible for the regulation of a variety of important functions within living organisms. Compounds which can selectively modulate aberrant PPIs are novel therapeutic candidates for treating human diseases. Whilst PPIs have traditionally been considered as “undruggable”, research in this area has led to the emergence of several effective methodologies for targeting PPIs. One such methodology is peptide stapling, which involves constraining a short peptide into its native alpha-helical form by forming a covalent link between two of its amino acid side-chains. The Sondheimer dialkyne reagent has previously been used in strain-promoted double-click cycloadditions with diazidopeptides to generate stapled peptides that are capable of inhibiting PPIs. However, the Sondheimer dialkyne suffers from poor water-solubility; it decomposes rapidly in aqueous solutions which limits its application in biological systems. This dissertation describes the design and synthesis of new substituted variants of the Sondheimer dialkyne with increased solubility and stability, that are suitable for application in strain promoted double click peptide stapling. In total, ten different derivatives were generated; of these, a meta-trimethylammonium substituted variant was found to have particularly high water-solubility and aqueous stability, as well as high azide reactivity. The substituted Sondheimer dialkynes were applied to the strain promoted double click stapling of p53-based diazido peptides in an effort to generate stapled peptide-based inhibitors of the oncogenic p53 MDM2 PPI, a validated target for anticancer therapeutics. Three stapled peptides were found to have inhibitory activity, thus demonstrating the utility of the novel dialkynes in the preparation of PPI inhibitors. The functionalised stapled peptide formed from a meta-fluoro substituted Sondheimer dialkyne was found to be the most potent inhibitor. All ortho-substituted Sondheimer dialkynes were found to be unreactive, whereas those with a meta-trimethylammonium substituent were highly reactive when compared to other meta-substituted dialkynes. These patterns in azide reactivity could be explained through X-ray crystallographic studies and density functional theory calculations.

 Material examined. Not collected in the current survey.
 Type locality. Long Island (previously Port Molle), Whitsunday Islands, Queensland, Australia.
 Remarks. Haswell’s (1885) original description and illustrations of this species are extremely sketchy, thus making it hard to discern from other species in the genus. The type material of P. laevis is lost (Springthorpe & Lowry 1994) and it has not been collected by any subsequent author since its original description (the records of Stebbing (1906, 1910) and Sheard (1937) given in the synonymy section above are based on that of Haswell, that is, these authors never actually examined any material of P. laevis). At this point, it must be considered as an unidentifiable species.

description: Cuba is a large neighbor of the U.S. Southeast with substantial export potential when the embargo is lifted. The present paper estimates the potential gains from trade in Southeastern agricultural export markets calibrating linear excess supply and excess demand to observed prices, outputs, exports, Cuban imports, and price elasticities in the literature. Linear excess supply and demand gauge market gains from trade in rice, grains, soybeans, poultry, pork, and meat. This paper is the first direct application of excess supply and excess demand with its focus on the international market and total surplus gains from trade. A brief review of Cuban trade history provides perspective on trade potential and motivates major assumptions of the model. The largest gains are for rice, grains, and soybeans with moderate gains for poultry and pork. Across these markets, total surplus increases over 3%.
