description: In early 2014 the fast-moving near-infrared source G2 reached its closest approach to the supermassive black hole Sgr A* in the Galactic Center. We report on the evolution of the ionized gaseous component and the dusty component of G2 immediately after this event, revealed by new observations obtained in 2015 and 2016 with the SINFONI integral field spectrograph and the NACO imager at the ESO VLT. The spatially resolved dynamics of the Br$γ$ line emission can be accounted for by the ballistic motion and tidal shearing of a test-particle cloud that has followed a highly eccentric Keplerian orbit around the black hole for the last 12 years. The non-detection of a drag force or any strong hydrodynamic interaction with the hot gas in the inner accretion zone limits the ambient density to less than a few 10$^3$ cm$^{-3}$ at the distance of closest approach (1500 $R_s$), assuming G2 is a spherical cloud moving through a stationary and homogeneous atmosphere. The dust continuum emission is unresolved in L'-band, but stays consistent with the location of the Br$γ$ emission. The total luminosity of the Br$γ$ and L' emission has remained constant to within the measurement uncertainty. The nature and origin of G2 are likely related to that of the precursor source G1, since their orbital evolution is similar, though not identical. Both object are also likely related to a trailing tail structure, which is continuously connected to G2 over a large range in position and radial velocity.

description: Students, based upon their daily experiences, develop their own models and understandings aboutseason cycle and day/night alteration. The latter arise from their physical senses, cultural background, discussions with their parents, peers interaction, language experiences, information from media and formalteaching. This study examined the ideas children hold about day/night and season cycles aswell as the extent to which these two phenomena are understood, or not, in the last two stages of primary education. The study also examined the differences between fifth and sixth grade students’ conceptualisation of the concepts involved in those two phenomena and the phenomena themselves.
Two types of spurious damping forces potentially modeled in numerical seismic nonlinear response history analysis

description: The purpose of this paper is to provide practitioners with further insight into spurious damping forces that can be generated in nonlinear seismic response history analyses (RHA). The term 'spurious' is used to refer to damping forces that are not present in an elastic system and appear as nonlinearities develop: such damping forces are not necessarily intended and appear as a result of modifications in the structural properties as it yields or damages due to the seismic action. In this paper, two types of spurious damping forces are characterized. Each type has often been treated separately in the literature, but each has been qualified as 'spurious', somehow blurring their differences. Consequently, in an effort to clarify the consequences of choosing a particular viscous damping model for nonlinear RHA, this paper shows that damping models that avoid spurious damping forces of one type do not necessarily avoid damping forces of the other type.

description: An observational constraint on the contribution of double degenerates to Type Ia supernovae requires multiple radial velocity measurements of ideally thousands of white dwarfs. This is because only a small fraction of the double degenerate population is massive enough, with orbital periods short enough, to be considered viable Type Ia progenitors. We show how the radial velocity information available from public surveys such as the Sloan Digital Sky Survey can be used to pre-select targets for variability, leading to a ten-fold reduction in observing time required compared to an unranked or random survey. We carry out Monte Carlo simulations to quantify the detection probability of various types of binaries in the survey and show that this method, even in the most pessimistic case, doubles the survey size of the largest survey to date (the SPY survey) in less than 15 per cent of the required observing time. Our initial follow-up observations corroborate the method, yielding 15 binaries so far (eight known and seven new), as well as orbital periods for four of the new binaries.

Identifying varietal differences in Spanish translations of The Great Gatsby
Creators: name: Muyor, Patricia Rodriguez
Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: This thesis presents a study of the analysis and contrast of literary translations of the same original novel. The study focuses on the Spanish translations of the American novel The Great Gatsby (Fitzgerald, 1925). The aim of the study is to analyse the different strategies applied by various translators when conveying the meaning from English into Spanish and to contrast and analyse the main differences among them. The study starts with an overview of the specific challenges of translating literary texts from English into Spanish, and how there are as many alternatives as Spanish dialects around the Spanish speaking geographic areas (Moreno Fernández, 2009). Furthermore, the Spanish varieties and their role in translation, the different approaches taken by translators (such as domestication and foreignization, Venuti 1995) and other areas that influence the topic of the study are described. The analysis of the dissimilarities and approaches among the translations leads into the analysis and validation of the Retranslation Hypothesis (Chesterman, 2004), to which a conclusion is formulated on the characteristics presented by the translations published between the years 1947 and 2015. A methodology is proposed in the study, which allows the research to identify the existence of specific geographic lexical items, i.e. regionalisms, among the translations as well as the approach followed throughout the translations. These regionalisms are representative of the different Spanish speaking geographical areas included in the study and help identify the translators’ approaches and the imprint that the Spanish varieties have on the target texts. Moreover, corpus-based analysis helps the study to analyse the representative lexical items, and to offer data that helps finding patterns or reasons behind translators’ choices.

description: The physics of tightly packed structures of a wire and other threadlike materials confined in cavities has been explored in recent years in connection with crumpled systems and a number of topics ranging from applications to DNA packing in viral capsids and surgical interventions with catheter to analogies with the electron gas at finite temperature and with theories of two-dimensional quantum gravity. When a long piece of wire is injected into two-dimensional cavities, it bends and originates in the jammed limit a series of closed structures that we call loops. In this work we study the extraction of a crumpled tightly packed wire from a circular cavity aiming to remove loops individually. The size of each removed loop, the maximum value of the force needed to unpack each loop, and the total length of the extracted wire were measured and related to an exponential growth and a mean field model consistent with the literature of crumpled wires. Scaling laws for this process are reported and the relationship between the processes of packing and unpacking of wire is commented upon.

Exploring unique optical properties of upconversion nanocrystals towards a new library of molecular probes
Creators: name: Zhao, Jiangbo
Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: This thesis explore the next-generation inorganic luminescent nanomaterial - upconversion nanocrystals, for advanced cell imaging and molecular sensing. Unlike traditional fluorochromes, e.g. fluorescent proteins and organic dyes, lanthanide-doped upconversion nanocrystals are able to efficiently convert the near-infrared excitation light to shorter wavelength emissions, e.g., the visible light. Upconversion nanocrystals are non-blinking, non-bleaching and immune to the autofluorescence interference, ideal for long-term background-free detecting trace amounts of target biomolecules or rareevent cells. The investigation of this thesis falls into two categories to advance upconversion nanocrystals to address needs of frontiers of bioimaging, biosensing, and biomedical diagnostics. The first part presents the explorartion towards lifetime-encoded multuplexed upconversion nanocrystals. We studied the impact of different nanocrystal sizes on optical properties of NaYF4:Er/Yb nanocrystals in both the spectral and temporal domains. We discovered the upconversion lifetime can be precisely tuned by controlling sizes of nanocrystals since the effect of surface quenching becomes increasingly dominating as the nanocrystals size shrinks. Combining with the fact that the lifetime can be engineered through varying dopants concentrations and tuning the fluorescence resonance energy transfer efficiency, respectively, we have established three independent mechanisms to produce non-crosstalking lifetimes and succeeded in demonstrating the lifetime multiplexing concept in the upconversion luminescence. In the second part, for the first time we discovered that the brightness of highly doped upconversion nanocrystals can be leveraged by a large dynamic range of excitation irradiance. We found that under the intense irradiance (unexplored regime previously), the concentration of Tm³⁺ emitters could be significantly increased from 0.5 mol% to 8 mol% in NaYF₄ nanocrystals without quenching the upconversion luminescence. This finding realized the remote tracking a single nanocrystal within the microstructured fibre dip sensor, which represents three orders of magnitude improvement than that of quantum dots. We also described that a combination of low-/high-Tm³⁺ doped upconversion nanocrystals holds the promise of being desirable luminescent nanomaterials for sensing, imaging, and security printing applications.

description: Limestone built heritage is at risk from the effects of biofilms, a microbial community encapsulated in a matrix of sugars, protein and extracellular DNA. Although biofilm research has been carried out in Mediterranean regions, few studies cover temperate Northern Europe climates, or the UK. This study concentrates on bacterial colonisation of Lincoln limestone, a highly vulnerable building material, and identifies the species, their role in biodeterioration and the efficacy of biocides against them.As part of this study the core species which comprise the bacterial component of the limestone microbiome have been characterised for the first time; this has allowed the identification of non-core species which are significantly associated with damaged and undamaged surfaces.Four mechanisms of biodeterioration have been identified, one previously unidentified, and isolated species have been characterised as to whether they are biodeteriorative and the mechanisms of biodeterioration that they employ. Two species, Curtobacterium flaccumfaciens and Solibacillus silvestris, have been characterised as producing biofilm matrix which actively causes biomechanical damage to the oolitic limestone structure as opposed to the passive enhancement of physical weathering which has been previously associated with biofilm matrix. Species capable of biodeterioration have also been shown to be present on both damaged and undamaged surfaces, something which has not been previously investigated.Environmental sampling, species identification and characterisation of species for biodeterioration have all combined to identify markers of biodeterioration, ie both physical markers and biomarkers. Specifically, a surface pH of 5.5 or lower and the presence of B. licheniformis is indicative of biodeterioration with a proportionally higher level of M. luteus when comparing damaged and undamaged stone.Finally this study brings the literature on conservation methods up to date by testing biocides which are in current usage, as many biocides in the literature are discontinued. This study is also the first in the field to show their efficacy against biofilm encapsulated bacteria and their propensity for chemically disrupting the biofilm matrix.

NFDI

description: The widespread usage of Jupyter notebooks across scientific disciplines highlights their fundamental importance in current research practices. However, their deployment across various NFDI consortia currently occurs through individual JupyterHubs, resulting in access barriers to computational and data resources. Only some of the services are widely available, and others are barricaded within VPNs, creating a fragmented landscape that complicates access. Our proposal aims to unify these efforts by offering a centralized service. We will simplify access, significantly improve the user experience, and extend the reach of Jupyter to a broader audience within the NFDI and beyond. We will integrate with IAM4NFDI to govern access to the central service and external resources, with future integrations planned with upcoming basic services such as Multi-Cloud or nfdi.software. Moreover, HPC resources from the GCS and the NHR Alliance will be accessible via the centralized Jupyter service, which lowers HPC entry barriers for a wide range of users. Importantly, the centralized system will not only simplify access but also support the import of projects along with their necessary dependencies, fostering an ecosystem conducive to creating reproducible FAIR Digital Objects (FDOs), possibly along with notebook identifiers supported by PID4NFDI. By ensuring a consistent user experience across all consortia, we will promote continued innovation. Our commitment is to a collaborative and centralized approach that brings Jupyter notebooks within everyone's reach and democratizes access to the infrastructures for reproducible computational research within the NFDI and beyond.

description: We report the discovery of periodic modulation of pulsation in 51 fundamental mode classical Cepheids of the Magellanic Clouds observed by the Optical Gravitational Lensing Experiment. Although the overall incidence rate is very low, about 1 per cent in each of the Magellanic Clouds, in the case of the SMC and pulsation periods between 12 and 16d the incidence rate is nearly 40 per cent. On the other hand, in the LMC the highest incidence rate is 5 per cent for pulsation periods between 8 and 14d, and the overall amplitude of the effect is smaller. It indicates that the phenomenon is metallicity dependent. Typical modulation periods are between 70 and 300d. In nearly all stars the mean brightness is modulated, which, in principle, may influence the use of classical Cepheids for distance determination. Fortunately, the modulation of mean brightness does not exceed 0.01 mag in all but one star. Also, the effect averages out in typical observations spanning a long time base. Consequently, the effect of modulation on the determination of the distance moduli is negligible. The relative modulation amplitude of the fundamental mode is also low and, with one exception, it does not exceed 6 per cent. The origin of the modulation is unknown. We draw a hypothesis that the modulation is caused by the 2:1 resonance between the fundamental mode and the second overtone that shapes the famous Hertzsprung bump progression.

description: The paper studies the problem of achieving consensus in multi-agent systems in the case where the dependency digraph $Γ$ has no spanning in-tree. We consider the regularization protocol that amounts to the addition of a dummy agent (hub) uniformly connected to the agents. The presence of such a hub guarantees the achievement of an asymptotic consensus. For the "evaporation" of the dummy agent, the strength of its influences on the other agents vanishes, which leads to the concept of latent consensus. We obtain a closed-form expression for the consensus when the connections of the hub are symmetric, in this case, the impact of the hub upon the consensus remains fixed. On the other hand, if the hub is essentially influenced by the agents, whereas its influence on them tends to zero, then the consensus is expressed by the scalar product of the vector of column means of the Laplacian eigenprojection of $Γ$ and the initial state vector of the system. Another protocol, which assumes the presence of vanishingly weak uniform background links between the agents, leads to the same latent consensus.

description: Molecular beam epitaxy technique has been used to deposit a single layer and a bilayer of MoSe 2 on sapphire. Extensive characterizations including in-situ and ex-situ measurements show that the layered MoSe 2 grows in a scalable manner on the substrate and reveals characteristics of a stoichiometric 2H-phase. The layered MoSe 2 exhibits polycrystalline features with domains separated by defects and boundaries. Temperature and magnetic field dependent resistivity measurements unveil a carrier hopping character described within two-dimensional variable range hopping mechanism. Moreover, a negative magnetoresistance was observed, stressing a fascinating feature of the charge transport under the application of a magnetic field in the layered MoSe 2 system. This negative magnetoresistance observed at millimeter-scale is similar to that observed recently at room temperature inWS2 flakes at a micrometer scale [Zhang et al., Appl. Phys. Lett. 108, 153114 (2016)]. This scalability highlights the fact that the underlying physical mechanism is intrinsic to these two-dimensional materials and occurs at very short scale.

An inquiry into adult male prisoners' experiences of education

Subjects: L300 - Sociology

description: Offender learning policy in England and Wales is vocationally focused and thus primarily aims to educate prisoners to increase their employability. Through an analysis of letters written by prisoners and interviews with serving prisoners, ex prisoners and prison staff, this qualitative study investigates prisoners’ experiences of education to explore the broad range of ways that such experiences are interpreted. A recurring interpretation involves personal development and this study shows that a range of personal changes and transformations can be attributed to prison education experiences. This suggests that prisoners’ interpretations of their educational experiences often go beyond employability.This study also provides a greater understanding of prisoners’ identities by drawing on elements of the research participants’ life histories and locating experiences of education within their narratives. This places the study in an in depth human context and as such, it has emerged that prisoners’ experiences of education can be better understood in the context of aspects of their life stories. This study reveals that prisoners who have not previously had positive educational experiences are often lacking in personal development and emotional maturity and therefore offender learning should be concerned with developing the ‘whole person’ in addition to giving prisoners skills for employment. As such, value can be ascribed to personal developments that are not directly related to employability such as the ability to cope with the experience of imprisonment and improved family relationships. By including such findings, this research also shows how understanding prisoners’ experiences of education contributes to understanding key themes in prison sociology: coping, masculinity, identity and the pains of imprisonment.This study concerns issues spanning a range of academic disciplines including criminology, sociology and education. As such, it is hoped that this thesis will be of interest to academics in the aforementioned subject areas as well as prison researchers, future prison researchers, prison teachers, prison staff, professionals in criminal justice, and any person with an interest in contemporary imprisonment.

Two-body problem in Scalar-Tensor theories as a deformation of General Relativity : an Effective-One-Body approach

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: In this paper we address the two-body problem in massless Scalar-Tensor (ST) theories within an Effective-One-Body (EOB) framework. We focus on the first building block of the EOB approach, that is, mapping the conservative part of the two-body dynamics onto the geodesic motion of a test particle in an effective external metric. To this end, we first deduce the second post-Keplerian (2PK) Hamiltonian of the two-body problem from the known 2PK Lagrangian. We then build, by means of a canonical transformation a ST-deformation of the general relativistic EOB Hamiltonian which allows to incorporate the Scalar-Tensor (2PK) corrections to the currently best available General Relativity EOB results. This EOB-ST Hamiltonian defines a resummation of the dynamics that may provide information on the strong-field regime, in particular, the ISCO location and associated orbital frequency and can be compared to other, e.g. tidal, corrections.
Investigating the Ligand Interactions Between E. coli PBP1b, Moenomycin-based Compounds, and Beta-Lactam Compounds

description: Antimicrobial resistance is a growing problem in this era. Resistance to the majority of clinicalantibiotics (including those of a ‘last line of defence’ nature) has been seen in a number oflaboratory and clinical settings. One method aiming at reducing this problem is alteringexisting antimicrobial compounds, in order to improve pharmacological effects (avoidingresistance mechanisms, improved spectrum of use). Looking at the interactions between theantimicrobial compounds and their targets can determine whether modifications to currentantimicrobials (such as moenomycin A) have altered the mode of action.ecoPBP1B is a bifunctional glycosyltransferase that could be used as a model for beta lactamsand moenomycins, aiding in the design and development of novel antimicrobials based onthese families. This project aims to show whether ecoPBP1b can be used as a model for novelantimicrobials, such as seeing whether novel MoeA analogues with peptides attached (tofacilitate entry into the bacterial cell) still retain their ability to bind to glycosyltransferases.In addition, this project looked at whether different beta-lactams would significantly alterthe conformation of the transpeptidase domain of ecoPBP1b.Building on previous studies into ecoPBP1b, we managed to successfully produce usablequantities of ecoPBP1b for crystallisation in conjunction with a variety of ligands. Crystalswere produced potentially containing complexes including such compounds as AI167-p andAI168-p (MoeA analogues), cefotaxime, cephradine, and a novel beta-lactamase inhibitor(CW-019).3D structures of ecoPBP1b in complex with AI167 were produced, successfully showing theMoeA analogue bound into the transglycosylase active site. This showed that the addition ofpeptides to the moenomycin molecule has not interfered with the interactions required forthe compound to bind to the transglycosylase domain. In addition, ecoPBP1b was cocrystallised with ampicillin bound to the penicillin binding region, matching with previousstudies.There are issues that need to be addressed with regards to ecoPBP1b before it can be usedas a reliable model, especially with beta-lactams. However, the main project goal (usingecoPBP1b for novel MoeA analogues) has been achieved, as well as furthering insights intocrystallisation of proteins in general.

description: We have derived an analytical formulation for estimating the volume of geometries enclosed by implicitly defined surfaces. The novelty of this work is due to two aspects. First we provide a general analytical formulation for all two-dimensional cases, and for elementary three three-dimensional cases by which the volume of general three-dimensional cases can be computed. Second, our method addresses the inconsistency issue due to mesh refinement. It is demonstrated by several two-dimensional and three-dimensional cases that this analytical formulation exhibits 2nd-order accuracy.

description: Pulmonary arterial hypertension (PAH) and Adams-Oliver syndrome (AOS) arerare vascular disorders, characterised by severe late-onset and developmentalcardiac abnormalities respectively. Both of them are clinically associated in aproportion of cases. PAH is a progressive condition that is clinically characterizedby sustained elevation in mean pulmonary artery pressure, through vascularremodelling with luminal obliteration of small vessels and increased vascularresistance. In addition, monoclonal proliferation and uncontrolled growth inpulmonary artery endothelial (PAEC) and smooth muscle (PASMC) cells result inperturbation and muscularization of the arterial tone. The disease may behereditary (HPAH), idiopathic (IPAH) or associated with other conditions, forexample AOS. Most of HPAH and 25% of IPAH cases are associated withheterozygous mutations of a TGF-? superfamily member transmembranereceptor type-II, known as BMPR2 on chromosome 2q33. The majority ofmutations suggest haploinsufficiency as the molecular mechanism of disease.While previous immunohistochemical studies of patient’s lung sections havereported further loss of BMPR-II than explained by haploinsufficiency, novelexperimentation reported Jun activation domain-binding protein 1 (JAB1) as aBMPR-II interacting partner. This study has progressed understanding of thisfunctional interaction in both physiological pathways and in the context of PAH.AOS disease displays multiple modes of inheritance and it is characterized bycongenital limb defects and scalp cutis aplasia, with notable pulmonary andcardiovascular involvement in a proportion of cases. Despite advances inunderstanding the genetic basis of AOS, for the majority of affected subjects theunderlined causative basis of disease remains poorly characterised. Recentnovel identification of 10 mutations (3 frameshifts, 6 missense and 1 nonsense)of the NOTCH1 gene in patients clinically characterized with AOS, indicatesNOTCH1 plays a key role in the AOS pathogenesis, and in particular, AOSassociated with congenital heart anomalies. This investigation comprises twomain avenues of research. First, to provide further insight into JAB1 mediatedBMPR-II down-regulation and degradation via the proteasomal pathway anddetermination of JAB1 dysregulation and role in the aggressive mitogenicproliferation potential, through reduction of SMAD signalling and consequentlyp38 MAPK and TAK1 activation observed in PAH cells. Second, to assessdysregulation of the Notch signalling pathway by assessment of NOTCH1 targetgenes HEY1 and HES1 expression. Finally, a signalling cross-talk between BMPand NOTCH1 pathways has been investigated to assess the impact of NOTCH1AOS-associated mutations on BMP signalling cascade.

description: In this paper, we introduce two measure theoretical notions of conditional entropy for finite measurable covers conditioned to a finite measurable partition and prove that they are equal. Using this we state a local variational principle with respect to the notion of conditional entropy defined by Misiurewicz in \cite{M} for the case of open covers. This in particular extends the work done in \cite{R} and \cite{HYZ}.
Masculinity in Australian film, 1949-1962

description: This thesis examines the representation of masculinity in Australian films released between 1949 and 1962. Rather than one distinct and fixed model of masculinity, this thesis argues that these Australian films from the fifties represented and negotiated predominantly – although not exclusively – between two competing understandings of masculinity. The first was a model best represented and advocated by Prime Minister Robert Menzies, whose explicit legitimation of middle-class masculinity marked an intervention into a longer national celebration of working-class values. The second, which itself represented a challenge to this middle-class intervention, was a distinct masculinity produced through the lens of radical nationalism. Connected to the working class, radical nationalism was a contemporary leftist intellectual movement that advocated a model of masculinity inspired by the Australian nineteenth century and challenged the ostensible synonymy of Menzies and the fifties. It is the longevity of Menzies’ prime ministerial reign that burdens popular images of the Australian postwar era. In both political discourse and popular culture, the fifties continue to function as a period of either stability and prosperity, or monotony and conformity. Existing historical literature has worked to dismantle this dichotomy, instead uncovering and drawing attention to the changes and transformations within both the social and political domains. Set against this backdrop of upheaval, compounded by the uncertainty of the Cold War, this thesis explores the transformations taking place in the cultural sphere of the postwar era. Rather than a passive reflection of social change, this thesis argues that the Australian cultural landscape, of which film was an important constituent, actively questioned and negotiated the competing and often contradictory meanings of masculinity that were in circulation in the fifties. Prioritising not the importance of a film’s author, but rather its meaning in a specific historical moment, this thesis’ exploration of fourteen Australian films through a variety of thematic analytical lenses demonstrates not only the multiple meanings of masculinity in circulation in this moment, but also film’s role in constituting these meanings. Indeed, that the tension between competing masculinities was unresolved not only across the fourteen films, but within certain films also, reveals the multiple understandings of culturally legitimate masculinity in the fifties while demonstrating film as both constituted by and constitutive of historically specific gendered meanings.

description: Infrared excesses around metal polluted white dwarfs have been associated with the accretion of dusty, planetary material. This work analyses the available infrared data for an unbiased sample of white dwarfs and demonstrates that no more than 3.3% can have a wide, flat, opaque dust disc, extending to the Roche radius, with a temperature at the disc inner edge of $T_{in} = 1,400$K, the standard model for the observed excesses. This is in stark contrast to the incidence of pollution of about 30%. We present four potential reasons for the absence of an infrared excess in polluted white dwarfs, depending on their stellar properties and inferred accretion rates: i) their dust discs are opaque, but narrow, thus evading detection if more than 85% of polluted white dwarfs have dust discs narrower than $δr< 0.04r$, ii) their dust discs have been fully consumed, which only works for the oldest white dwarfs with sinking timescales longer than hundreds of years, iii) their dust is optically thin, which can supply low accretion rates of $<10^7 $gs$^{-1}$ if dominated by PR-drag, and higher accretion rates, if inwards transport of material is enhanced, for example due to the presence of gas, iv) their accretion is supplied by a pure gas disc, which could result from the sublimation of optically thin dust for T* > 20, 000K. Future observations sensitive to faint infrared excesses or the presence of gas, can test the scenarios presented here, thereby better constraining the nature of the material fuelling accretion in polluted white dwarfs.

Title: The Confession Formula: A Philosophical Argument Against P = NP

 

Description:

This paper introduces a conceptual framework called the Confession Formula—a metaphorical and mathematical argument suggesting that P ≠ NP unless problems can reveal their own solutions without computational interrogation. Drawing on analogies from logic, computation, and symbolic philosophy, the author argues that the key difference between P and NP lies not in the difficulty of finding answers, but in the nature of how answers are revealed. The paper proposes that without a formula that causes a number to "confess" all valid internal combinations, NP problems will always remain computationally intractable. The work aims to open new philosophical and structural perspectives on the P vs NP question, blending intuitive reasoning with foundational inquiry.

Semantic transformations for XML queries

description: "The ever-increasing adoption of XML has created a need to ensure that XML query languages perform efficiently. Query optimization and transformation for XML query languages, both syntactically and semantically, have received much attention from research communities in recent years. However, due to the fast progress of the application of XML data management solutions, XML-Enabled Database Management Systems still face several challenges. Among these challenges is query processing, especially the processing of XML queries specified with XPath axes and redundancies that may exist in predicates used in XML queries. Semantic query optimization utilizes constraints in XML schemas to directly optimize a given query with a set of optimization rules. Due to the current complexity of the XML data structure which is enabled by rich semantics in XML Schemas, semantic query optimization should be performed in a more systematic manner. For a complete solution, this research proposes a series of semantic transformations to transform given XML queries to semantically equivalent, but more efficient, XML queries for optimization purposes, by using the semantics provided in XML Schemas. The proposed semantic transformations are grouped into three categories: (1) Semantic Path Transformations, (2) Semantic Transformations for XPath Queries Specified with Predicates, and (3) Semantic Transformations for XPath Queries Specified with XPath Axes. After a semantic transformation is applied to an XML query, the equivalent semantic XML query can be processed more efficiently by an XML data management system and returns the same result set. The proposed semantic transformations are then translated into a series of algorithms which are implemented and empirically evaluated for their efficiency and effectiveness. The experimental studies were carried out by using both real data sets (DBLP) and Benchmark data sets (Michigan) to illustrate that the majority of semantic transformations achieved significantly improved performance in XML query processing; this also enabled the research presented here to identify semantic transformations as optimization devices". -- Abstract.
