Effects of hydrodynamic interaction on an AUV operating close to a moving submarine
Creators: name: Leong, Zhi Quan
Publisher: name: University Of Tasmania
Year: 2023
Subjects: Ship and platform structures (incl. maritime hydrodynamics)

description: The work detailed in this thesis investigates the behaviour of the hydrodynamic interaction effects acting on an unappended AUV manoeuvring in proximity to a larger moving underwater vehicle such as a submarine. The investigation examined the steady-state and transient interaction effects on the hydrodynamic coefficients of the AUV as a function of the relative: speed, longitudinal position, lateral position, and size between the two submerged vehicles. The work involved extensive development of Computational Fluid Dynamics (CFD) models to simulate the manoeuvres in order to map the interaction behaviour. Experimental Fluid Dynamics (EFD) involving captive-model tests of the two vehicles were carried out to validate and supplement the CFD data. The results show that the hydrodynamic interaction acts to attract and repel the AUV at the stern and bow regions around the submarine, respectively. The magnitude of these attraction and repulsion interaction effects varied significantly due to small changes in the relative longitudinal position, suggesting the need of an accurate and fast responsive control system for the AUV to adequately maintain its trajectory around the submarine. These adverse interaction effects were found to be minimal around amidships of the moving submarine, suggesting a safe path for the AUV to approach or depart the submarine laterally within that region. In addition, the interaction effects on the hydrodynamic coefficients of the AUV were shown to reduce as the relative speed of the latter increased. Due to the need to simulate large relative motions between the two vehicles, this thesis also investigate and identifies the merits of two dynamic mesh techniques within ANSYS CFX (i.e. Immersed Solids, and AMP Re-Meshing) to simulate multiple bodies in relative motion. Although the numerical models behind the techniques have undergone substantial development in recent years, as they are beta-features in ANSYS CFX there are currently no existing studies demonstrating their capabilities in modelling multiple bodies in relative motion. The developed CFD simulation models are suitable for future work involving appended AUVs and the coupling with a control system for manoeuvring simulations of multiple underwater vehicles.

description: Excerpts from the report: This report covers results of a study of nine branch livestock markets representing three regional cooperatives in Ohio, Indiana, and Michigan. Object of the study was to find ways to help these and similar livestock markets improve their efficiency. Each of the nine markets operated a weekly auction. In addition most of them also sold some livestock – primarily hogs -- on other days of the week. During the study, the facility layout and operation of each was studied in detail and records showing volume of receipts and detailed costs and income were analyzed. This report thus shows comparisons of these nine markets. It also gives suggestions for improved efficiency based on these findings.

Why "a few" and why not *"a many"?
Creators: name: Solt, Stephanie
Publisher: name: ZAS Papers in Linguistics
Year: 2006

description: The expressions few and a few are typically considered to be separate quantifiers. I challenge this assumption, showing that with the appropriate definition of few, a few can be derived compositionally as a + few. The core of the analysis is a proposal that few has a denotation as a one-place predicate which incorporates a negation operator. From this, argument interpretations can be derived for expressions such as few students and a few students, differing only in the scope of negation. I show that this approach adequately captures the interpretive differences between few and a few. I further show that other such pairs are blocked by a constraint against the vacuous application of a.

We provide an example where the inflaton decay products subsequently generate a lepton asymmetry and a dark matter abundance with an unique coupling in the early universe, while the present day decay of the dark matter through the same coupling gives rise the observed cosmic ray anomalies at PAMELA and Fermi Large Area Telescope.

Spin-like current from phase space distributions

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

description: The spin 0 generalized phase space approach provides a general expression for local current which depends on the choice of distribution function and generally deviates from the Schrodinger current. It is shown that the continuity equation restricts the admissible bilinear distributions such that the current has a unique dependence on the wavefunction and coincides with the non-relativistic limit of the relativistic spin 1/2 current for a spin eigenstate, up to a constant vector. Examples of non-bilinear distributions that have the latter property are given.

description: We calculate the cross section of the exclusive process $e^{+} +e^{-}\to J/ψ+η_c$ at the leading order approximation within the QCD light-cone sum rules (LCSR) approach. It is found that the form factor $F_{VP}(V=J/ψ,P=η_c)$ depends mainly on the behavior of the twist-2 distribution amplitude of the $η_c$-meson at the scale of this process. Thus in order to obtain a reliable estimation of the cross section, it is important to have a realistic distribution amplitude of the $η_c$ meson, and to deal with the evolution of the distribution amplitude to the effective energy scale of the process. Our results show that one can obtain a compatible prediction with the Belle and BarBar experimental data.

Presuppositons in processing: a case study of German "auch"
Creators: name: Schwarz, Florian
Publisher: name: ZAS Papers in Linguistics
Year: 2006

description: This paper presents two experimental studies investigating the processing of presupposed content. Both studies employ the German additive particle auch (too). In the first study, participants were given a questionnaire containing bi-clausal, ambiguous sentences with 'auch' in the second clause. The presupposition introduced by auch was only satisfied on one of the two readings of the sentence, and this reading corresponded to a syntactically dispreferred parse of the sentence. The prospect of having the auch-presupposition satisfied made participants choose this syntactically dispreferred reading more frequently than in a control condition. The second study used the self-paced-reading paradigm and compared the reading times on clauses containing auch, which differed in whether the presupposition of auch was satisfied or not. Participants read the clause more slowly when the presupposition was not satisfied. It is argued that the two studies show that presuppositions play an important role in online sentence comprehension and affect the choice of syntactic analysis. Some theoretical implications of these findings for semantic theory and dynamic accounts of presuppositions as well as for theories of semantic processing are discussed.

description: In the recent past, there has been a concerted effort to develop mathematical models for real-world networks and to analyze various dynamics on these models. One particular problem of significant importance is to understand the effect of random edge lengths or costs on the geometry and flow transporting properties of the network. Two different regimes are of great interest, the weak disorder regime where optimality of a path is determined by the sum of edge weights on the path and the strong disorder regime where optimality of a path is determined by the maximal edge weight on the path. In the context of the stochastic mean-field model of distance, we provide the first mathematically tractable model of weak disorder and show that no transition occurs at finite temperature. Indeed, we show that for every finite temperature, the number of edges on the minimal weight path (i.e., the hopcount) is $Θ(\log{n})$ and satisfies a central limit theorem with asymptotic means and variances of order $Θ(\log{n})$, with limiting constants expressible in terms of the Malthusian rate of growth and the mean of the stable-age distribution of an associated continuous-time branching process. More precisely, we take independent and identically distributed edge weights with distribution $E^s$ for some parameter $s>0$, where $E$ is an exponential random variable with mean 1. Then the asymptotic mean and variance of the central limit theorem for the hopcount are $s\log{n}$ and $s^2\log{n}$, respectively. We also find limiting distributional asymptotics for the value of the minimal weight path in terms of extreme value distributions and martingale limits of branching processes.

Word-meaning and sentence-internal presupposition

Publisher: name: ZAS Papers in Linguistics
Year: 2006

description: The German causal preposition durch ('by', 'through') poses a challenge to formal-semantic analyses applying strict compositionality. To deal with this challenge, a formalism which builds on recent important developments in Discourse Representation Theory is developed, including a more elaborate analysis of presuppositional phenomena as well as the integration into the theory of unification as a mode of composition. It is argued that that the observed unificational phenomena belong in the realm of pragmatics, providing an argument for presuppositional phenomena at a sentence- and word-internal level.

description: Lithium intercalated anatase used in Li-ion batteries has some special features: coexistence of Li-rich and Li-poor phases as well as two possible positions for Li ions in the oxygen tetrahedron. A theoretical description of the compound considering those peculiarities is presented. As shown by the performed symmetry analysis, the intercalation induced lattice deformation can be accompanied by the ordering of antiferroelectric type (internal piezoeffect). In the following step, a qualitative illustration of the phase separation in the lithiated anatase is given within the Landau expansion at the proper choice of coefficients. A microscopic model for description of the compound is also proposed which combines features of the Mitsui and Blume-Emery-Griffits models and utilizes the symmetry analysis results. Various ground state and temperature-dependent phase diagrams of the model are studied to find a set of model parameters corresponding to the lithiated anatase. A phase separation into the empty and half-filled phases in a wide temperature range has been found closely resembling the phase coexistence in the intercalated crystal. In the framework of the model, the two-position Li subsystem could have the ordering of ferro- or antiferroelectric types which, however, has not been yet observed by the experiment.

'Almost there': the meaning of "almost"
Creators: name: Penka, Doris
Publisher: name: ZAS Papers in Linguistics
Year: 2006

description: Modifiability by almost has been used as a test for the quantificational force of a DP without stating the meaning of almost explicitly. The aim of this paper is to give a semantics for almost applying across categories and to evaluate the validity of the almost test as a diagnosis for universal quantifiers. It is argued that almost is similar to other cross-categorial modifiers such as at least or exactly in referring to alternatives ordered on a scale. I propose that almost evaluates alternatives in which the modified expression is replaced by a value close by on the corresponding Horn scale. It is shown that a semantics for almost that refers to scalar alternatives derives the correct truth conditions for almost and explains selectional restrictions. At the same time, taking the semantics of almost seriously invalidates the almost test as a simple diagnosis for the nature of quantifiers.

description: Through a Metropolis-like algorithm with single step computational cost of order one, we build a Markov chain that relaxes to the canonical Fermi statistics for k non-interacting particles among m energy levels. Uniformly over the temperature as well as the energy values and degeneracies of the energy levels we give an explicit upper bound with leading term km(ln k) for the mixing time of the dynamics. We obtain such construction and upper bound as a special case of a general result on (non-homogeneous) products of ultra log-concave measures (like binomial or Poisson laws) with a global constraint. As a consequence of this general result we also obtain a disorder-independent upper bound on the mixing time of a simple exclusion process on the complete graph with site disorder. This general result is based on an elementary coupling argument and extended to (non-homogeneous) products of log-concave measures.

Forking paths and polarity items licensing
Creators: name: Panzeri, Francesca
Publisher: name: ZAS Papers in Linguistics
Year: 2006

description: There is an elegant account, proposed by Beaver and Condoravdi (2003), that assumes that the temporal connectives before and after are converses (i.e., they are analyzed by means of a unified lexical schema), and that explains away their different logical and veridical behavior appealing to other factors. There is an elegant explanation that connects the licensing of Polarity Items to informational strengthening requirements: Polarity Items are viewed as existentials that lead to a widening of the domain of quantification, and they are predicted to be legitimate only when this widening leads to a stronger statement (roughly, in downward monotone contexts). My plan is to connect these two approaches – by proposing an amendment in the definition Beaver and Condoravdi presented for before and after that is meant to account also for their Polarity Items licensing behavior.

description: Modal items of different semantic types can only be combined in a specific order. Epistemic items, for instance, cannot be embedded under deontic ones. I'll argue that this fact cannot be explained by the current semantic theories of modality. A solution to this problem will be developed in an update semantics framework. On the semantic side, a distinction will be drawn between circumstantial information about the world and information about duties, whereas I'll use Nuyts' notion of m-performativity to account for certain use of the modal items.

Direct numerical simulations of the galactic dynamo in the kinematic growing phase

description: We present kinematic simulations of a galactic dynamo model based on the large scale differential rotation and the small scale helical fluctuations due to supernova explosions. We report for the first time direct numerical simulations of the full galactic dynamo using an unparameterized global approach. We argue that the scale of helicity injection is large enough to be directly resolved rather than parameterized. While the actual superbubble characteristics can only be approached, we show that numerical simulations yield magnetic structures which are close both to the observations and to the previous parameterized mean field models. In particular, the quadrupolar symmetry and the spiraling properties of the field are reproduced. Moreover, our simulations show that the presence of a vertical inflow plays an essential role to increase the magnetic growth rate. This observation could indicate an important role of the downward flow (possibly linked with galactic fountains) in sustaining galactic magnetic fields.

Communications and political behavior in the international system; explorations into theory, method, and substance
Creators: name: McMaster, Barrie Glenholme
Publisher: name: University of British Columbia
Year: 2012

description: This study deals with possible relationships between the political information levels of nation states and their behavior in the international political system. The purpose of the study is purely exploratory. Drawing upon the literature of domestic political participation studies and the systems framework of David Easton, the author investigates the relevance and implications of the hypothesis, the availability and reliability of data sources, and the substantive relationship between information and behavior. The author suggests that a basic modification of the Easton model— the addition of a membership environment— makes the framework applicable to the analysis of international politics, and shows political information to be a salient variable, previously over looked in systemic analyses of international relations. Attention is devoted to the utility of news index and news summary sources for behavioral data. Using correlational techniques, the investigator finds that the advantages of availability and economy of these sources are somewhat offset by the existence of biases; no conclusions can be drawn, the author suggests, until a more systematic assessment of these sources is undertaken. Using a randomization test for matched pairs of twenty nation states, the study indicates a probable relationship between the extent of information channels and the systemic orientation of states' international behavior. The information channels utilized in the research design are diplomatic exchanges and memberships in inter-governmental organizations. The substantive findings are then related to the behavioral data source question, and to the further research ability of the problem. The author concludes that the results of the pilot study are sufficiently interesting to warrant fuller investigation of both the hypothesis and the source bias problem.
present perfect at the semantics/pragmatics interface: American English and Brazilian Portuguese
Creators: name: Molsing, Karina Veronica
Publisher: name: ZAS Papers in Linguistics
Year: 2006

description: Modern theorists rarely agree on how to represent the categories of tense and aspect, making a consistent analysis for phenomena, such as the present perfect, more difficult to attain. It has been argued in previous analyses that the variable behavior of the present perfect between languages licenses independently motivated treatments, particularly of a morphosyntactic or semanticsyntactic nature (Giorgi & Pianesi 1997; Schmitt 2001; Ilari 2001). More specifically, the wellknown readings of the American English (AE) present perfect (resultative, experiential, persistent situation, recent past (Comrie 1976)), are at odds with the readings of the corresponding structure in Brazilian Portuguese (BP), the 'pretérito perfeito composto' (default iterativity and occasional duration (Ilari 1999)). Despite these variations, the present work, assuming a tense-aspect framework at the semantic-pragmatic interface, will provide a unified analysis for the present perfect in AE and BP, which have traditionally been treated as semantically divergent. The present perfect meaning, in conjunction with the aspectual class of the predicate, can account for the major differences between languages, particularly regarding iterativity and the "present perfect puzzle", regarding adverb compatibility.

On temporally bounded quantification over eventualities
Creators: name: Móia, Telmo
Publisher: name: ZAS Papers in Linguistics
Year: 2006

description: This paper focuses on different subtypes of constructions involving temporally bounded quantification, e.g. sequences like David visited Rome three times followed by temporal phrases as different as (i) last year, which defines a time interval; (ii) in less that two months, which defines an amount of time; and (iii) per month, which refers to a time unit. As for the first two types of temporal phrases, data will be presented which shows that they have specific linguistic properties in these quantifying contexts, and do not behave exactly as the locating or duration adverbials they are superficially identical with. The third type of phrases will receive special attention. Structures with frequency adverbials like n times per month will be analysed compositionally, separating the quantified component n times from the temporally binding phrase per month (whose role is comparable to that of adverbials (i) and (ii) in the relevant constructions). The data presented is mainly from Portuguese, although the issues at stake – the linguistic properties of temporally bounded quantification – are obviously relevant to parallel constructions in other languages.

description: The list update problem is a classical online problem, with an optimal competitive ratio that is still open, known to be somewhere between 1.5 and 1.6. An algorithm with competitive ratio 1.6, the smallest known to date, is COMB, a randomized combination of BIT and the TIMESTAMP algorithm TS. This and almost all other list update algorithms, like MTF, are projective in the sense that they can be defined by looking only at any pair of list items at a time. Projectivity (also known as "list factoring") simplifies both the description of the algorithm and its analysis, and so far seems to be the only way to define a good online algorithm for lists of arbitrary length. In this paper we characterize all projective list update algorithms and show that their competitive ratio is never smaller than 1.6 in the partial cost model. Therefore, COMB is a best possible projective algorithm in this model.

A Multispectral Image Processing of Spot and TM Landsat data permits to understand the behaviour of the past land cover dynamics; a multi-temporal analysis of Normalized Difference Vegetation and Hydric Stress index, most informative RGB (according to statistical criteria) and Principal Components, points out the importance and the direction of environmental impacts. We gain from the Remote Sensing images new environmental criteria (distance from roads, oil pipe-line, DEM, etc.) which influence the spatial allocation of predicted land cover probabilities. We are comparing the results of different prospective approaches (Markov Chains, Multi Criteria Evaluation and Cellular Automata; Neural Networks) analysing the residues for improving the final model of future deforestation risk.

description: We study the dynamics of entanglement in a two-qubit system interacting with a squeezed thermal bath via a dissipative system-reservoir interaction with the system and reservoir assumed to be in a separable initial state. The resulting entanglement is studied by making use of a recently introduced measure of mixed state entanglement via a probability density function which gives a statistical and geometrical characterization of entanglement by exploring the entanglement content in the various subspaces spanning the two-qubit Hilbert space. We also make an application of the two-qubit dissipative dynamics to a simplified model of quantum repeaters.

We consider a realistic scenario in which an ancillary system with a limited number of levels performs restricted sequential interactions with qubits in a row. The proposed method relies on a suitable local optimization procedure, yielding an efficient recipe for the realistic and approximate sequential generation of any entangled multiqubit state. We give paradigmatic examples that may be of interest for theoretical and experimental developments.

The figures of Charles Jencks, “semiology and architecture”
Creators: name: Steen, Andrew
Publisher: name: University Of Tasmania
Year: 2023
Subjects: Architectural history, theory and criticism

description: This thesis addresses English-language architectural theory discourse. It is an interrogation of the intellectual history of architectural theory language. While explicitly a contribution towards understanding a discrete discursive territory in existence in 1969, the study’s significance extends to the broader fields of architectural writing and design.

 The thesis investigates one text: Charles Jencks’s “Semiology and Architecture”, chapter one of Meaning in Architecture, an anthology edited by Jencks and George Baird. This single text is taken as a case study: it is used to assess the significance and functioning of the language and structure of address of so-called architectural theory.

 The thesis focuses in particular on the diagrammatic figures within “Semiology and Architecture”. Highly formal extensions of Jencks’s written body, the figures concentrate attention on the message as matter, and encourage an analysis directed towards the text’s paradigmatic axis. The figures’ conspicuous in-text presence helps denaturalize names and reify concepts, modifying the communicative role of each of these linguistic units.

 This thesis argues that the figures and names, thus understood, change the fundamental nature of “Semiology and Architecture”. Under their influence, the referential function of the text — that aspect supporting the argument — is repeatedly usurped by the poetic function. This pattern acts to disrupt commonsense assumptions regarding authorship. In place of a distinct Jencks, the thesis extracts authorial constructs or personas.

 This thesis uses the poetic function of Jencks’s text, and its authorial constructs, to characterize the underlying discursive formation. Each of the thesis’s five body chapters performs the same set of operations. One or two figures are isolated; Jencks’s argument as determined by referential function is traced, and the paradigmatic selections demonstrative of the poetic function analyzed; the relevant textual constructs are exposed; and the discursive functioning is characterized, significance thus articulated.

 Through close textual analyses, this thesis contributes novel understandings of Charles Jencks, “Semiology and Architecture”, and the ongoing practice of architectural writing. It advances historical and theoretical arguments: it addresses the function of the author and the process of writing within architecture’s discursive formation, and advocates for the significance of formal textuality in studies of architectural theory.

We derive stringent bounds on relevant R-parity violating couplings, which are based on all existent experimental upper limits of involved semi-leptonic decays. In addition, we also investigate the sensitivities of the branching ratios and di-neutrino invariant mass spectra to the survived R-parity violating coupling spaces. Since the experimental bounds would become much better soon through Super-B, we expect that future experiments will greatly strengthen our bounds.

description: The village has been the significant social unit on the Indian subcontinent for thousands of years. To maintain its integrity it has developed a set of interlocking structures, some of which are unique to the subcontinent, which are very resistant to change. The Indian national government passed legislation which provided for the formation of new structures of political allocation without providing the basis of support for changing the other related structures existing within the village. This thesis attempts to show why this particular change, advocated by the state and national governments, failed.

description: A greener and inexpensive electrochemical method has been developed for the oxidation of benzyl alcohols by homogeneous electrolysis. The electrochemical reaction was carried out in an undivided cell equipped with carbon and stainless steel electrodes at room temperature. The homogeneous solution made up of acetonitrile/water containing substrate and ammonium bromide with a catalytic amount of H2SO4 as supporting electrolyte. The reaction condition was optimized with various electrochemical experimental parameters and evaluated with various substituted benzyl alcohols to result in excellent yield of aldehydes (>83%).

description: This study investigates macrostructure in elicited narratives of 69 monolingual German-, Russian- and Swedish-speaking adults. Using the LITMUS-MAIN (Multilingual Assessment Instrument for Narratives), and its Baby Goats and Baby Birds stories, story structure and story complexity, concerning episodic organization, were examined across the 3 languages. As theoretical underpinnings, a multidimensional model of macrostructure was used. This model includes analyses of story structure (SS), in which a narrative merits a maximum score of 17, based on the occurrence of five types of macrostructural components (Internal states as initiating event and as reaction, Goal, Attempt and Outcome), and of story complexity (SC), which measures combinations of Goals, Attempts and Outcomes within one episode. The highest attainable complexity is the GAO-sequence, when a Goal, Attempt and Outcome are produced within the same episode. The results for SS were similar for German, Russian and Swedish, where adults included 11-12 components per story. A more detailed analysis of the individual components revealed striking similarities across the 3 languages, both for frequently used and seldom occurring components. SC did not differ significantly across languages nor across stories, whilst for SS, a slight difference between the two stories was found. We interpret this finding as story complexity (a qualitative measure of macrostructure) being of a more universal nature. Furthermore, our results indicate that caution is warranted when conclusions about children’s narrative skills are to be drawn on the basis of the MAIN Baby Goats and Baby Birds stories.

description: For this study one hundred sixty-seven Russian-/Turkish-German preschool children were tested with a battery of language proficiency tests in both languages. On the basis of 1.5 SD below monolingual norm for L2 German and 1.25 SD below bilingual mean for either home language, 9 children at risk of developmental language disorders (DLD) (mean age of 4 years and 5 months) were identified and 16 age-matched TD children were selected out of the cohort. All these children were tested with the LITMUS-MAIN and –SR tests in German. The results across TD and at risk of DLD group were compared. TD clearly outperformed at risk of DLD in SR. In elicited narratives, macrostructure and microstructure were scrutinized across groups. Similar to the previous findings, our results show significant differences between at risk of DLD und TD in the microstructure, e.g. total number of word tokens and verb-based communication units and SR. For the macrostructure, TD outperformed at risk children only for story complexity. The study expands our knowledge on the cut-off criteria for the identification of bilinguals at risk of DLD, scrutinized very early narratives for bilinguals at risk of DLD features and questions the similarity of cognitive skills in TD and at risk of DLD children.

description: An efficient and facile method has been developed for the synthesis of chiral β-amino bromides from their corresponding alcohols under Appel reaction conditions. This approach allows for the deoxybromination of a variety of β-amino alcohols in excellent yields under mild conditions without any detectable racemization.
Einfluss des Bildaufbaus in Narrativen auf die Erzählkomplexität von Vorschulkindern – eine empirische Vergleichsstudie

description: The aim of the present study was to test the influence of picture composition on the narrative complexity of preschool children, and to compare the different procedures of the Cat Story of Hickmann (2002) and the Fox Story of Gülzow & Gagarina (2007) with the Baby Birds and Baby Goats Story of MAIN, by Gagarina et al. (2012). For this purpose, 27 children between the ages of 5;01 and 6;09 were tested with both variants to check whether a macro-structurally controlled picture structure would lead to more complex stories. The results show that narratives with a Goal-Attempt-Outcome structure, i.e. the Baby Birds and Baby Goats Stories, make children with increasing age tell more complex stories by means of a rise in story complexity than the narratives of Hickmann and Gülzow & Gagarina without that structure.

description: Electronic resources, encompassing a diverse array of digitized information formats, constitute a cornerstone of modern information ecosystems, underpinned by technological infrastructure and human interaction. This paper delves into the multifaceted nature of electronic resources, elucidating their various forms, including text, multimedia, and online databases. Drawing upon insights from Tsakonas and Papatheodorou (2006), the study defines electronic resources as encompassing full-text documents, CD-ROMs, and internet-based resources such as eJournals and Online Public Access Catalogues (OPACs). Specifically focusing on the context of the University of Cape Coast (UCC), this research centers on electronic resources comprising OPAC, DSpace, and academic databases. By exploring the landscape of electronic resources within the university setting, this study aims to provide a comprehensive understanding of their role in facilitating access to scholarly information and supporting research and learning endeavors. Through empirical analysis and theoretical insights, this paper seeks to shed light on the utilization and impact of electronic resources in enhancing academic pursuits and advancing knowledge dissemination within the academic community. Ultimately, this research contributes to the broader discourse on electronic resource management, informing strategies for optimizing their accessibility, usability, and effectiveness in academic settings
Isospin mixing and the continuum coupling in weakly bound nuclei

description: The isospin breaking effects due to the Coulomb interaction in weakly-bound nuclei are studied using the Gamow Shell Model, a complex-energy configuration interaction approach which simultaneously takes into account many-body correlations between valence nucleons and continuum effects. We investigate the near-threshold behavior of one-nucleon spectroscopic factors and the structure of wave functions along an isomultiplet. Illustrative calculations are carried out for the T=1 isobaric triplet. By using a shell-model Hamiltonian consisting of an isoscalar nuclear interaction and the Coulomb term, we demonstrate that for weakly bound or unbound systems the structure of isobaric analog states varies within the isotriplet and impacts the energy dependence of spectroscopic factors. We discuss the partial dynamical isospin symmetry present in isospin-stretched systems, in spite of the Coulomb interaction that gives rise to large mirror symmetry breaking effects.

description: Acetylation of 2-amino-4-(4-methoxyphenyl)-6-oxo-1,6-dihydropyrimidine-5-carbonitrile (2) using acetic anhydride afforded N-pyrimidinylacetamide derivative 3 which upon formylation using Vilsmeier-Haack reagent produced β-chloroenaldehyde derivative 4. The chemical behavior of compound 4 was investigated toward some primary amines as well as heterocyclic amines yielding the corresponding Schiff bases. Compound 4 is used as a building block for the construction of nitrogen heterocyclic compounds such as pyrazoles, pyrimidines, pyridopyrimidine and diazepine through its reaction with a diversity of bifunctional nucleophiles such as hydrazines, guanidines, 6-aminouracil and ethylenediamine. The biological activity of the synthesized compounds was investigated. Structures of the newly synthesized products were deduced on the basis of their analytical and spectral data.
