description: We study spherically symmetric spacetimes for matter distributions with isotropic pressures. We generate new exact solutions to the Einstein field equations which also contains isotropic pressures. We develop an algorithm that produces a new solution if a particular solution is known. The algorithm leads to a nonlinear Bernoulli equation which can be integrated in terms of arbitrary functions. We use a conformally flat metric to show that the integrals may be expressed in terms of elementary functions. It is important to note that we utilise isotropic coordinates unlike other treatments.

description: We describe the investigation of high-spin states in 24Mg populated with the 12C(16O,α)24Mg reaction at 62- and 68-MeV beam energy. The excited states were established through the coincident detection of up to four α and γ particles in complete decay cascades toward a final state of angular momentum zero, the ground state of either 20Ne or 16O. We describe a new analysis method for the angular correlations in such events and apply it with the goal to assign spin and parity to α-unbound states in 24Mg. We establish a number of high-spin, natural-parity states between spins 6 and 12, including the lowest known 10+ and 12 + levels. The energy systematics of positive- and negative-parity high-spin states are compared to the predictions of modern shell-model calculations.

description: The Vehicle Scheduling Problem (VSP) is a well-studied combinatorial optimization problem arising for bus companies in public transport. The objective is to cover a given set of timetabled trips by a set of buses at minimum costs. The Electric Vehicle Scheduling Problem (E-VSP) complicates traditional bus scheduling by considering electric buses with limited driving ranges. To compensate these limitations, detours to charging stations become necessary for charging the vehicle batteries during operations. To save costs, the charging stations must be located within the road network in such a way that required deadhead trips are as short as possible or even redundant. For solving the traditional VSP, a variety of solution approaches exist capable of solving even real-world instances with large networks and timetables to optimality. In contrast, the problem complexity increases significantly when considering limited ranges and chargings of the batteries. For this reason, there mainly exist solution approaches for the E-VSP which are based von heuristic procedures as exact methods do not provide solutions within a reasonable time. In this paper, we present a literature review of solution approaches for scheduling electric vehicles in public transport and location planning of charging stations. Since existing work differ in addition to the solution methodology also in the mapping of electric vehicles' technical aspects, we pay particular attention to these characteristics. To conclude, we provide a perspective for potential further research.

description: Abstract: The present research study explores the significance of different dramatic techniques used by the playwright Roy Williams in his portrayal of realistic social issues of black-white relationships in the British multiracial in his play Joe Guy (2007). The objective of this research paper is to assess the importance of different dramatic devices or techniques used by Roy Williams to depict racial and social problems of his contemporary British society. Williams through his use of unique dramatic techniques, explores the central issue of racial discrimination by the mainstream white and West Indian origin black British people against African blacks in the society. The playwright’s fame as the most skilled and versatile black British playwright rests on his abilities to explore racial issues by using some unique techniques like shifting of time, radio playing, stage directions, dramatic monologue, and asides in Joe Guy. Williams perfectly blends all these techniques to achieve the goal of exploring the underlining racial and identity issues of African blacks in the British urban society. Work of literature is a direct reflection of the author’s real experiences and close personal observations of the surrounding situations. Roy Williams being the skilled dramatist gives shocking experiences and surprises to the audience by exploring the reality through his innovative and unique dramatics techniques in the play. Williams’s this particular skill makes him unique and the most acknowledged black British playwright in the British theatre. Apart from the main plot which contains journey of Joe Guy, a black premier footballer from a poor boy to celebrity footballer like Beckham and his subsequent imprisonment on rape charges. Williams through his dramatic techniques exposes underlying dark truths and racially biased mentalities of the mixed race people living in British society.

description: A capital project is a complex product acquired by an owner company as a major investment for long-term revenue generation. Project owners expect their capital project performance to represent an efficient use of the organization’s capital. Thus, they are motivated to improve capital efficiency. Project capital efficiency can be impacted by how well the business unit aligns with the project unit. Indeed, these two units must collaborate in the early project phases to determine how the project will be built and operated. This dissertation has been undertaken so as to improve project capital efficiency through better business-project collaboration. To achieve this objective, the author identified business-project management processes that impact project capital efficiency. The processes were characterized and quantitively analyzed based on the survey data. When implemented effectively, these management processes also advance cross-functional collaboration and help the business and project units achieve strategic alignment. Further, this research theorized the mediation effect of strategic alignment and the moderation effects of senior management and project complexity factors on the relationship between business-project collaboration and project capital efficiency. To analyze the survey data and validate the hypotheses, the author used the technique of partial least squares structural equation modeling (PLS-SEM). Findings first confirmed that strategic alignment is a significant mediator; hence, business and project units should always seek to achieve it. Findings also approved the moderator roles of decision autonomy as a senior management factor and uncertainty as a project complexity factor in the relationship between cross-functional collaboration and strategic alignment. This research also identified barriers and contributing factors that hinder effective cross-functional collaboration in the early project phases. To help improve future collaborative efforts, the author ranked these barriers using the Delphi technique. As for the contributions of this research, the first is the identification, characterization, and quantitative analysis of the business-project management processes that impact project capital efficiency. A second is the confirmation of the mediating role of strategic alignment and moderating roles of certain senior management and project complexity factors. A third is the identification of cross-functional barriers and contributing factors and ranking of the barriers to further enhance the effectiveness of the collaboration.

description: The topic of this paper is the relationship between journalism and science. In order to describe a potentially relevant dynamic in this relationship, the German sociologist of science Peter Weingart proposed the term "medialization." It describes phenomena of change within science, such as the oversimplification or exaggeration of research findings, which are associated with an increased need for public attention within science. This concept focuses on the repercussions of journalism on science. Inscribed in the term is the assumption that journalism potentially has great social significance. At the very least, journalism, or the mass media it dominates, is thought to influence processes of change within science. The paper aims to assess the social impact of science reporting in order to plausibilize the significance of the role played by journalism. This is based on recent, partly unpublished empirical findings by a German-French DFG/ANR project, which relate to the ability of journalism to focus public attention on scientific events and actors. The results are essentially negative, in the sense that journalism hardly, or at best only very sporadically, succeeds in focusing public attention on individual scientific events or actors. Based on the journalism’s very limited performance in this regard, we consider it implausible that journalism could be as significant a factor as the concept of medialization indicates.

description: We have monitored twelve T dwarfs with the Kitt Peak 2.1m telescope using an f814w filter (0.7-0.95 microns) to place in context the remarkable 10-20% variability exhibited by the nearby T dwarf Luhman 16B in this wavelength regime. The motivation was the poorly known red optical behavior of T dwarfs, which have been monitored almost exclusively at infrared wavelengths, where variability amplitudes greater than 10% have been found to be very rare. We detect highly significant variability in two T dwarfs. The T2.5 dwarf 2MASS 13243559+6358284 shows consistent ~17% variability on two consecutive nights. The T2 dwarf 2MASS J16291840+0335371 exhibits ~10% variability that may evolve from night to night, similarly to Luhman 16B. Both objects were previously known to be variable in the infrared, but with considerably lower amplitudes. We also find evidence for variability in the T6 dwarf J162414.37+002915.6, but since it has lower significance, we conservatively refrain from claiming this object as a variable. We explore and rule out various telluric effects, demonstrating that the variations we detect are astrophysically real. We suggest that high-amplitude photometric variability for T dwarfs is likely more common in the red optical than at longer wavelengths. The two new members of the growing class of high-amplitude variable T dwarfs offer excellent prospects for further study of cloud structures and their evolution.

description: High-spin states in the odd-proton thulium isotopes 173Tm and 175Tm have been studied using deep-inelastic reactions and γ-ray spectroscopy. In 173Tm, the low-lying structure has been confirmed and numerous new states have been identified, including a three-quasiparticle Kπ= 19/2- isomer with a lifetime of τ=360(100)ns at 1906keV and a five-quasiparticle Kπ=35/2- isomer with a lifetime of τ= 175(40)ns at 4048keV. The Kπ=35/2- state is interpreted as a t-band configuration that shows anomalously fast decays. In 175Tm, the low-lying structure has been reevaluated, a candidate state for the 9/2-[514] orbital has been identified at 1175keV, and the 7/2-[523] bandhead has been measured to have a lifetime of τ= 460(50)ns. Newly identified high-K structures in 175Tm include a Kπ=15/2- isomer with a lifetime of τ= 64(3)ns at 947keV and a Kπ= 23/2+ isomer with a lifetime of τ= 30(20) μs at 1518keV. The Kπ=15/2- isomer shows relatively enhanced decays to the 7/2-[523] band that can be explained by chance mixing with the 15/2- member of the 7/2- band. Multiquasiparticle calculations have been performed for 173Tm and 175Tm, the results of which compare well with the experimentally observed high-spin states.

description: This paper develops a two-step inference procedure to test for a local one-for-one relation of contemporaneous jumps in high-frequency financial data corrupted by market microstructure noise. The first step develops a new bivariate Lee-Mykland jump test for pre-averaged, intra-day returns. If a jump is detected in at least one of the two assets, then the second step tests for equal jump sizes. We apply the test procedure to pairs of nominal and inflationindexed government bond yields at monetary policy announcements in the U.S., U.K., and Euro Area. The analysis provides new high-frequency evidence about the anchoring of inflation expectations and central banks’ ability to push a measure of inflation expectations towards their inflation target.

We confirm earlier theoretical predictions about the structure of these defects and identify new features in the electron energy-loss spectra (EELS) of B atoms using high resolution chemical maps, highlighting differences between these areas and pristine sample regions. We correlate our experimental data with calculations which help explain our observations.

description: The evolution of the one-quadrupole phonon mixed-symmetry state is important for understanding the role of the quadrupole proton-neutron interaction in the valence shell. To study the evolution of the 21,ms+ mixed-symmetry state in the N=78 isotones above Z=50, a Coulomb excitation measurement was performed to identify the 21,ms+ state in 136Ce by measuring absolute transition strengths. The 21,ms+ state was found to be predominantly concentrated in the 24+ state of this nucleus. The simple picture of shell stabilization given to account for the fragmentation of the strength observed in 138Ce does not seem to apply to 136Ce.

description: The dense shell method for the determination of distances to type IIn supernovae has been briefly reviewed. Applying our method to SN 2006gy, SN 2009ip, and SN 2010jl supernovae, we have obtained distances in excellent agreement with the previously known distances to the parent galaxies. The dense shell method is based on the radiation hydrodynamic model of a supernova. The method of the blackbody model, as well as the correctness of its application for simple estimates of distances from observation data, has been justified.

description: By using the wave function ansatz method, we study the energy eigenvalues and wave function for any arbitrary $m$-state in two-dimensional Schrödinger wave equation with various power interaction potentials in constant magnetic and Aharonov-Bohm (AB) flux fields perpendicular to the plane where the interacting particles are confined. We calculate the energy levels of some diatomic molecules in the presence and absence of external magnetic and AB flux fields using different potential models. We found that the effect of the Aharonov-Bohm field is much as it creates a wider shift for $m\neq 0$ and its influence on $m=0$ states is found to be greater than that of the magnetic field. To show the accuracy of the present model, a comparison is made with those ones obtained in the absence of external fields. An extension to 3-dimensional quantum system have also been presented.

description: Deep-Inelastic reactions have been used to populate high-spin states in the even-even osmium isotopes and in the iridium neighbors. New isomers have been identified in 190Os, 192Os, 194Os, 191Ir and 193Ir. These include a 2 ns 12+ state at 2865 keV and a 295 ns, 20+ state at 4580 keV in 192Os. Although a number of multi-quasiparticle states arising from prolate and triaxial deformations are expected in these nuclei, the main structures in 192Os can be interpreted as a two-stage alignment of i13/2 neutrons at oblate deformation, in close analogy with similar structures in the isotones 194Pt and 196Hg. The isomers are attributed to low-energy E2 transitions at the point of the alignment gains. The isomer observed in 191Ir is long-lived (τm ∼8s) and probably arises from coupling of the h11/2 proton to the 10 -ν/9/2- [505]11/2+ [615] prolate configuration that gives rise to long-lived isomers in 190Os and 192Os, although potential-energy-surface calculations indicate that the resultant three-quasiparticle state will be triaxial.

Year: 1998

description: In this thesis an approach for efficiently computing a compact spectral/temporal feature set for representing a segment of speech, with effective resolution depending on both frequency and time position within the segment, is developed, analyzed, and tested. The goal of this method is to mimic the resolution properties of the human auditory system, but using a computationally efficient FFT-based front end rather than a more complex auditory model. In particular this method applies both frequency and time "warping" to FFT spectra to obtain good frequency resolution at low frequencies and good time resolution at high frequencies. Time resolution is also varied so that the center of the segment is better represented than the endpoints. The resolution can be varied by the selection of "warping" functions controlled using a small number of parameters. The method was experimentally verified for both phonetic classification and isolated word recognition. Results of 81.2% for the six stops /b, d, g, p, t, k/ are among the best reported in the literature. Finally, the ASM was implemented in a Visual Speech Display system for recognition of consonant-vowel-consonant (CVC) words in-real time.
An investigation into novel technologies for better surgeon integration in robotic assisted orthopaedic surgery
Creators: name: Liu, He
Publisher: name: Imperial College London
Year: 2019

description: Robotic and computer technologies have been integrated into orthopaedic surgery to assist surgeons with complicated procedures, and the improvements in surgical accuracy have been clinically validated in studies worldwide. However, higher surgical accuracy is achieved at the expense of higher procedural complexity, leading to an unnatural workflow and lower efficiency in the operating room. In this thesis, a surgeon-centred surgical workflow is proposed so that technical assistance can be provided to the surgeon more efficiently. The primary contribution is a novel registration method for orthopaedic surgery based on depth imaging, which utilises the surface geometry of the bone, instantaneously captured by a depth camera, to localise the bone automatically. The fast capture rate of the depth camera enables real-time bone tracking without percutaneous markers. To obtain the bone surface from depth images, free from surrounding tissues, artificial neural networks have been established and trained to identify the surgical site and then segment out the desired part on the depth image of the surgical site. Robotics has also been integrated into the registration process, with the depth camera mounted on its end-effector, to track the registration target in motion. An obstacle avoidance algorithm has been designed for the robot to move the camera away from potential obstacles, which reduces the risk of line-of-sight interruption. Finally, utilising the registration results, an intuitive surgical navigation system has been developed based on augmented reality. Three-dimensional holographic surgical navigation is overlaid on the patient's anatomy directly, which exempts the surgeon from looking away to external monitors, thus improving procedural efficiency. Experimental validation of these contributions shows the potential of integrating these novel technologies naturally into the surgical workflow, demonstrating that the use of robotics and computer navigation could not only provide reliable surgical accuracy, but also improve ergonomics and efficiency in robot/computer assisted orthopaedic procedures.

The magnetic susceptibility and magnetic specific heat of the compound exhibit thermally activated behavior below approximately 1 K. Furthermore, its magnetization curve is observed up to the saturation field and directly indicates a zero-field excitation gap of 0.5 T. These experimental results provide evidence for the existence of a Haldane gap. We successfully explain the results in terms of the $S=1/2$ F-AF AHC through quantum Monte Carlo calculations with $|J_{\rm{AF}}/J_{\rm{F}}|$ = 0.22. The $ab$ $initio$ MO calculations also indicate a weak AF interchain interaction $J'$ and that the coupled F-AF AHCs form a honeycomb lattice. The $J'$ dependence of the Haldane gap is calculated, and the actual value of $J'$ is determined to be less than 0.01$|J_{\rm{F}}|$.

Publisher: name: University of Glasgow

description: African trypanosomes evade the mammalian host immune system for prolonged periods by periodically switching the protective Variant Surface Glycoprotein (VSG) coat expressed on their cell surface. Recombination reactions, which introduce novel VSG gene copies into specialised expression sites, constitute the principal mechanism of this antigenic variation process. Since VSG genes occupy cassettes with common upstream and downstream sequences it is hypothesised that VSG switching reactions occur primarily by homologous recombination. It has previously been shown that at least some of the VSG switching reactions are either catalysed or regulated by RAD51, a fundamental component of the homologous recombination machinery in eukaryotes. In order to investigate further the factors regulating antigenic variation we have characterised several components of the highly conserved post-replicative mismatch repair (MMR) system in T. brucei. The nuclear MMR system recognises mispaired bases in heteroduplex recombination intermediates preventing recombination between divergent DNA molecules, and thereby confining such reactions to highly homologous sequences. In yeast and mammals this system is composed of three homologues of the bacterial MutS enzyme and three bacterial MutL-related enzymes. We have identified five single-copy genes putatively encoding three MutS homologues and two MutL homologues, suggesting that most of the components of eukaryotic MMR are conserved in trypanosomes. Knockout mutants have been generated in two of the genes, MSH2 and MLH1, to investigate the activities of MMR in this organism. Both MSH2-deficient and MLH1- deficient trypanosomes exhibit microsatellite instability, a mutator phenotype, and tolerance to the methylating agent MNNG, demonstrating that these genes encode components of an active MMR system in T. brucei. Moreover, deletion of MSH2 increases the frequency of recombination between 3% divergent sequences, revealing that MMR is also involved in the regulation of recombination in this organism. Despite this, no effect on the frequency or mechanisms used in antigenic variation was observed in either MSH2 or MLH1 mutants, suggesting that MMR has little or no influence on this process, and that perhaps the homologous recombination reactions underlying antigenic variation proceed by a mechanism distinct from general recombination.

description: While pathogen genomic data is generally considered to be non-identifying, the associated contextual data and the potential of amplifying the human host genetic sequences are potentially sensitive. It is often the cumulation and combination of indirect identifiers that makes a specific dataset identifiable. While data sharing of pathogen genomic data in a timely manner has a direct impact on our collective health, real-time sharing of such data is a challenge due to discoverability and privacy issues

 Galaxy has gained a Beacon integration that enables users to publish genetic variance data conveniently via Beacon project. The Beacon network enables querying genomic variant catalogues without the risk of exposing sensitive data Beacon facilitates the first-contact and speeds up knowledge exchange dramatically.

 In the infectious diseases context using microbial genomics data, lack of the reference genomes has been a challenge to allow mutation-based data discovery until recently. The latest development in the pathogen genomics data ecosystem, thanks to the COVID-19 pandemic, offers a promising roadmap on how pathogen genomics data discovery can be enhanced using tools such as Beacon based on a mutation.

 Privacy Enhanced Technologies (PETs) are emerging technologies that can provide new ways for data sharing. Secure Multiparty Computation (SMC) is one of the PETs, and supports computations of inputs from different organizations without revealing each party's input. Private Set Intersection (PSI) and Linear secret sharing (LSS) are commonly used methods in SMC

description: Intermediate-energy Coulomb excitation measurements were performed on the neutron-rich isotopes 58,60,62Cr. The electric quadrupole excitation strengths, B(E2; 01+→21+), of 60,62Cr are determined for the first time. The results quantify the trend of increasing quadrupole collectivity in the Cr isotopes approaching neutron number N=40. The results are confronted with large-scale shell-model calculations in the fpgd shell using the state-of-the-art LNPS effective interaction. Different sets of effective charges are discussed that provide an improved and robust description of the B(E2) values of the neutron-rich Fe and Cr isotopes in this region of rapid shell evolution. The ratio of the neutron and proton transition matrix elements, |Mn/Mp|, is proposed as an effective tool to discriminate between the various choices of effective charges.

description: One of the most intriguing open issues in galaxy evolution is the structure and evolution of active galactic nuclei (AGN) that emit intense light believed to come from an accretion disk near a super-massive black hole (Rees 1984, Lynden-Bell 1969). To understand the zoo of different AGN classes, it has been suggested that all AGN are the same type of object viewed from different angles (Antonucci 1993). This model -- called AGN unification -- has been successful in predicting e.g. the existence of hidden broad optical lines in the spectrum of many narrow-line AGN. But this model is not unchallenged (Tran 2001) and it is an open problem whether more than viewing angle separates the so-called Type-1 and Type-2 AGN. Here we report the first large-scale study that finds strong differences in the galaxy neighbours to Type-1 and Type-2 AGN with data from the Sloan Digital Sky Survey (SDSS) (York et al. 2000) Data Release 7 (DR7) (Abazajian et al. 2008) and Galaxy Zoo (Lintott et al, 2008, Lintott et al 2011). We find strong differences in the colour and AGN activity of the neighbours to Type-1 and Type-2 AGN and in how the fraction of AGN residing in spiral hosts changes depending on the presence of a neighbour or not. These findings suggest that an evolutionary link between the two major AGN types might exist.

description: Excerpt from the booklet: The goal of this booklet is to explain the basic principles of agricultural competitiveness from three different perspectives — economics and policy, geography, and history. The three points of view are not mutually exclusive but strongly overlapping. We will begin with a review of the basic economic principles that underlie successful competition, show how international conditions and policies can modify these underlying principles, illustrate with maps and other diagrams the present structure of international agriculture, and then trace the trends that have brought us to the current juncture.

description: Material emitted as ejecta from ONe novae outbursts is observed to be rich in elements as heavy as Ca. The bottleneck for the synthesis of elements beyond sulphur is the P30(p,γ)S31 reaction. Its reaction rate is, however, not well determined due to uncertainties in the properties of key resonances in the burning regime. In the present study, gamma-ray transitions are reported for the first time from all key states in S31 relevant for the P30(p,γ)S31 reaction. The spins and parity of these resonances have been deduced, and energies have been measured with the highest precision to date. The uncertainty in the estimated P30(p,γ)S31 reaction rate has been drastically reduced. The rate using this new information is typically higher than previous estimates based on earlier experimental data, implying a higher flux of material processed to high-Z elements in novae, but it is in good agreement with predictions using the Hauser-Feshbach approach at higher burning temperatures.

description: A γ-ray spectroscopy study of 30S is presented. Excitation energies have been determined with improved precision over previous studies and firm spin-parity assignments have been made for key 29P+p resonant states. An evaluation of the 29P(p,γ)30S reaction for T=0.08-2.5 GK shows that the 3+ and 2+ resonant states located at Er=289(3) and 410(3) keV, respectively, dominate the 29P(p,γ)30S reaction rate in ONe novae, while the 410-keV resonance is expected to govern the rate in x-ray burster environments. These new, precise resonance energy measurements and firm spin-parity assignments have significantly reduced uncertainties in the 29P(p,γ)30S reaction in ONe novae and x-ray bursts. In particular, the reaction rate is now specified precisely enough for calculations of isotopic abundances in ONe novae ejecta.

description: Rotation-vibration spectra of the nitric acid molecule, HNO\3, are calculated for wavenumbers up to 7000~\cm. Calculations are performed using a Hamiltonian expressed in internal curvilinear vibrational coordinates solved using a hybrid variational-perturbation method. An initial potential energy surface (PES) and dipole moment function (DMF) are calculated {\it ab initio} at the CCSD(T)/aug-cc-pVQZ level of theory. Parameters of the PES and DMF are varied to minimize differences between the calculated and experimental transition frequencies and intensities. The average, absolute deviation between calculated and experimental values is 0.2~\cm\ for frequencies in the fundamental bands and 0.4~\cm\ for those in the first overtone and lowest combination bands. For the intensities, the calculated and experimental values differ by 0.3\% and 40\% for the fundamentals and overtones, respectively. The optimized PES and DMF are used to calculate the room-temperature ro-vibrational spectrum. These calculation reproduce both the form of the absorption bands, and fine details of the observed spectra, including the rotational structure of the vibrational bands and the numerous hot absorption band. Many of these hot bands are found to be missing from the compilation in HITRAN. A room temperature line list comprising $2 \times 10^{9}$ lines is computed.

Effective field theories of gravity: a top-down approach
Creators: name: Harrold, Alexander
Publisher: name: Imperial College London

description: From water boiling to the behaviour of magnets, the world around us is often described using the language of Effective Field Theory. This powerful framework is often employed to model a system in terms of its low energy degrees of freedom without much thought being given to the higher energy origins of the model. In this thesis we shall attempt to turn this idea on its head by constructing effective theories by beginning from the high energy theory and then arriving at the low energy description. Our main aim shall be to address this issue in the context of deriving the EFT of perturbations around a background solution of Type IIA Supergravity given by Crampton, Pope and Stelle that involves the non-compact hyperbolic space H 2,2 . Studying the subject of EFTs in the context of Type IIA Supergravity presents it’s own challenges as this theory exists in ten spacetime dimensions, whilst our observed universe is four dimensional. We shall present how to address this issue of dimensional mismatch using Kaluza-Klein methods and discuss aspects of the resulting lower dimensional field with an eye towards achieving lower dimensional diffeomorphism invariance. This treatment shall lead us to the conclusion that a previously undiscovered Stueckelberg field must be accounted for and dealt with if one is to appropriately understand the lower dimensional theory. We also exhibit a generalisation of the solutions of Crampton, Pope and Stelle to include time dependence. Such solutions may have applications to cosmological models.

description: Abstract— Purpose: The objective of this study was to assess the relationship of ANB angle and Overjet using Lateral Cephalometry. Methods and material: The sample included 75 Cephalometric radiographs of patients ranging in age from [15-25] that were selected and collected from the Department of Radiology Faculty of Dentistry (Suez Canal University) .The cephalometric radiographs were divided according to ANB angle into three equal groups with twenty five cephs.in each group,group 1: Twenty Five for Skeletal Class I, group 2: Twenty Five for Skeletal Class II, and group 3: Twenty Five for Skeletal Class III. The relationship between ANB angle and Overjet was measured. Results:The correlational analysis of overjet with ANB angle in the three malocclusion classes showed, In Class-I showed a weak nonsignificant correlation (r= 0.266; p= 0.198). However, in Class-II, showed a positive significant correlation between overjet and ANB angle (r=0.792; p<0.001). ClassIII showed a weak to moderate correlation (r= 0.479; p=0.015). Conclusions:ANB angle can be considered as a good predictor for overjet significantly in class II, but in class I and class III, ANB angle is a weak predictor for overjet.

Revealed preferences over experts and quacks and failures of contingent reasoning

Subjects: information structure, contingent reasoning, belief updating, heuristics

description: In many economic scenarios, people resort to different tests to obtain information about the payoff-relevant states of the world. This paper studies how people evaluate and choose between useless tests (quacks) and genuinely useful ones (experts). Using a novel graphic experiment, I recover individual preferences over tests. I find people fail to distinguish between experts and quacks. Their quack choices are not driven by standard explanations, including belief updating bias, best-responding bias, and intrinsic preference of information. The main culprit is the failure in reasoning the contingency value of tests for their decision problems.
