Stakeholder perceptions of selection: analysis of applicants' and stakeholders' perceptions of methods used to select medical students in undergraduate medical education
Creators: name: Brown, Jeffrey Edward

Subjects: Other education not elsewhere classified

description: Examining personnel selection solely from an organisational perspective has traditionally been the dominant paradigm within Industrial/Organisational (I/O) psychology (Anderson, Lievens, van Dam, & Ryan, 2004). However, in recent years there has been a move to explore selection from the applicants' perspective. This thesis extends the existing literature by examining applicants' as well as other key stakeholders' perceptions of the validity of the methods used in the high-stakes context of medical student selection. Ryan and Ployhart's (2000) comprehensive model of applicant perceptions was applied in three empirical studies. The first and second studies examined how applicants and non-applicant stakeholders respectively, perceive the validity of the methods used to select medical students into an initial degree, and to identify factors that influence perceived validity. The third study aimed to determine whether individuals' perceptions of each selection method's validity would impact on overall confidence in the selection process. The influence of moderating variables on this relationship was also explored. Results showed that interviews were perceived as the most valid selection method by all participant groups, with cognitive ability tests and references rated as the least valid. Perceived validity was predicted to the extent participants thought the selection methods were susceptible to ethnic discrimination, by the type of skills they thought doctors required, familiarity with the methods, and demographic factors. Perceived validity of cognitive ability and measures of academic performance were significant predictors of applicants' confidence that the best people are being selected as future doctors, while non-applicant stakeholders' confidence was affected by perceived validity of the test of cognitive ability and of interviews. Moderation analyses provided support for the hypothesis of a differential effect for applicants and non-applicants regarding how a method's perceived susceptibility to artificially enhance performance would influence the relationship between its perceived validity and confidence. Strengths and limitations of this thesis are presented, together with implications for practice and future research.

description: It has not been determined definitively whether there is a significant association between diabetes mellitus (DM) and glaucoma. Some population-based studies have shown a positive association between diabetes and glaucoma, and others have shown negative association between diabetes and glaucoma. However in many studies that showed a lack of a significant association between diabetes and glaucoma, the diagnosis of DM was made by self-presentation. On the other hand, DM was diagnosed by the serum glucose level or by glucose tolerance tests in the Rotterdam Study. The study concluded that the risk of open angle glaucoma was increased by more than three times in patients with diabetes than without diabetes. The results of a recent metaanalysis suggested that diabetes was a significant risk factor for open angle glaucoma. However, two of 12 studies included in the meta-analysis used only high intraocular pressure (IOP) as a definition of open angle glaucoma. Thus, patients with normal tension glaucoma were not included in the glaucoma group. More exact definitions of DM and glaucoma should be used to determine more accurately the association between DM and glaucoma. The results of these studies indicate that there is insufficient clinical evidence to conclude that there is a significant relationship between diabetes mellitus and glaucoma.

description: In this work, an adaptive predictive control scheme for linear systems with unknown parameters and bounded additive disturbances is proposed. In contrast to related adaptive control approaches that robustly consider the parametric uncertainty, the proposed method handles all uncertainties stochastically by employing an online adaptive sampling-based approximation of chance constraints. The approach requires initial data in the form of a short input-output trajectory and distributional knowledge of the disturbances. This prior knowledge is used to construct an initial set of data-consistent system parameters and a distribution that allows for sample generation. As new data stream in online, the set of consistent system parameters is adapted by exploiting set membership identification. Consequently, chance constraints are deterministically approximated using a probabilistic scaling approach by sampling from the set of system parameters. In combination with a robust constraint on the first predicted step, recursive feasibility of the proposed predictive controller and closed-loop constraint satisfaction are guaranteed. A numerical example demonstrates the efficacy of the proposed method.

description: We report the operation of an optical parametric amplifier (OPA) capable of producing gigawatt peak-power laser pulses with tunable wavelength in either the visible or near-infrared spectrum. The OPA has two distinct operation modes (i) generation of >350 uJ, sub 100 fs pulses, tunable between 1250 - 1550 nm; (ii) generation of >190 uJ, sub 150 fs pulses tunable between 490 - 530 nm. We have recorded high-order harmonic spectra over a wide range of driving wavelengths. This flexible source of femtosecond pulses presents a useful tool for exploring the wavelength-dependence of strong-field phenomena, in both the multi-photon and tunnel ionization regimes.

description: This paper begins with a review of the well-known KdV hierarchy, the $N$-th Novikov equation, and its finite hierarchy in the classical commutative case. This finite hierarchy consists of $N$ compatible integrable polynomial dynamical systems in $\mathbb{C}^{2N}$. We discuss a non-commutative version of the $N$-th Novikov hierarchy defined on the finitely generated free associative algebra ${\mathfrak{B}}_N$ with $2N$ generators. Using the method of quantisation ideals in ${\mathfrak{B}}_N$, for $N=1,2,3,4$, we obtain two-sided homogeneous ideals ${\mathfrak{Q}}_N\subset{\mathfrak{B}}_N$ (quantisation ideals) that are invariant with respect to the $N$-th Novikov equation and such that the quotient algebra ${\mathfrak{C}}_N = {\mathfrak{B}}_N/ {\mathfrak{Q}}_N$ has a well-defined Poincare-Birkhoff-Witt basis. This allows us to define the quantum $N$-th Novikov equation and its hierarchy on ${\mathfrak{C}}_N$. We derive $N$ commuting quantum first integrals (Hamiltonians) and represent the equations of the hierarchy in the Heisenberg form. Essential for our research is the concept of cyclic Frobenius algebras, which we introduced in our recent paper. In terms of the quadratic form that defines the structure of a cyclic Frobenius algebra, we explicitly express the first integrals of the $N$-th Novikov hierarchy in the commutative, free, and quantum cases.

description: Recently, a new treatment to the vitreoretinal interface diseases, vitreous injection of enzymatic vitreous melting drug is beginning to take place. This is a treatment to release the adhesion between the incompletely detached vitreous and the retina. Because the vitreous is transparent, to observe the relationship between the vitreous and the retina using only slit lamp microscope is difficult, optical coherence tomography (OCT) is necessary for adaptation decision of the vitreous injection. How useful is the diagnostic imaging of the vitreous by current OCT?

description: Ancestral Ties, Visions of Nature and Settler Territoriality. In May 2017 the Australian Referendum Council convened a meeting at Uluru in Central Australia of over two hundred and fifty Indigenous leaders to discuss constitutional reform to recognise Aboriginal and Torres Strait Islander peoples. After four days of discussion the delegates resolved to call for the establishment of a “First Nations Voice” in the Australian Constitution and a “Makarrata Commission” to pursue reconciliation. These resolutions were detailed in the Uluru Statement from the Heart, a one-page declaration of Aboriginal and Torres Strait Islander history and sovereignty that pleaded for “substantive constitutional change” and “structural reform.” The Statement pivoted on notions of ownership and belonging. It insisted on the link between Indigeneity, spirituality, and territory. The statement detailed the “ancestral tie” that Aboriginal and Torres Strait Islander peoples share with “the land, or 'mother nature'” and maintained that those “peoples who were born therefrom” and “remain attached thereto” must “one day return thither to be united with our ancestors.” This sovereign link, argued the convention, “has never been ceded or extinguished, and co-exists with the sovereignty of the Crown.” In a tradition well established in Australian and settler colonial politics, the calls of the convention were sadly, and predictably, rejected by the Commonwealth government in October of 2017. In light of this “betrayal,” two powerful questions within the Uluru Statement stand out: “How could it be otherwise? That peoples possessed a land for sixty millennia and this sacred link disappears from world history in merely the last two hundred years?”. 'How could it be otherwise?' is a question that haunts the settler nations of the Pacific Rim.

description: We present Submillimeter Array 880 $μ$m dust polarization observations of six massive dense cores in the DR21 filament. The dust polarization shows complex magnetic field structures in the massive dense cores with sizes of 0.1 pc, in contrast to the ordered magnetic fields of the parsec-scale filament. The major axes of the massive dense cores appear to be aligned either parallel or perpendicular to the magnetic fields of the filament, indicating that the parsec-scale magnetic fields play an important role in the formation of the massive dense cores. However, the correlation between the major axes of the cores and the magnetic fields of the cores is less significant, suggesting that during the core formation, the magnetic fields below 0.1 pc scales become less important than the magnetic fields above 0.1 pc scales in supporting a core against gravity. Our analysis of the angular dispersion functions of the observed polarization segments yields the plane-of-sky magnetic field strengths of 0.4--1.7 mG of the massive dense cores. We estimate the kinematic, magnetic, and gravitational virial parameters of the filament and the cores. The virial parameters show that in the filament, the gravitational energy is dominant over magnetic and kinematic energies, while in the cores, the kinematic energy is dominant. Our work suggests that although magnetic fields may play an important role in a collapsing filament, the kinematics arising from gravitational collapse must become more important than magnetic fields during the evolution from filaments to massive dense cores.

description: We consider the problem of routing in a mobile ad-hoc network (MANET) for which the planned mobilities of the nodes are partially known a priori and the nodes travel in groups. This situation arises commonly in military and emergency response scenarios. Optimal routes are computed using the most reliable path principle in which the negative logarithm of a node pair's adjacency probability is used as a link weight metric. This probability is estimated using the mobility plan as well as dynamic information captured by table exchanges, including a measure of the social tie strength between nodes. The latter information is useful when nodes deviate from their plans or when the plans are inaccurate. We compare the proposed routing algorithm with the commonly-used optimized link state routing (OLSR) protocol in ns-3 simulations. As the OLSR protocol does not exploit the mobility plans, it relies on link state determination which suffers with increasing mobility. Our simulations show considerably better throughput performance with the proposed approach as compared with OLSR at the expense of increased overhead. However, in the high-throughput regime, the proposed approach outperforms OLSR in terms of both throughput and overhead.

description: Natural image matting estimates the alpha values of unknown regions in the trimap. Recently, deep learning based methods propagate the alpha values from the known regions to unknown regions according to the similarity between them. However, we find that more than 50\% pixels in the unknown regions cannot be correlated to pixels in known regions due to the limitation of small effective reception fields of common convolutional neural networks, which leads to inaccurate estimation when the pixels in the unknown regions cannot be inferred only with pixels in the reception fields. To solve this problem, we propose Long-Range Feature Propagating Network (LFPNet), which learns the long-range context features outside the reception fields for alpha matte estimation. Specifically, we first design the propagating module which extracts the context features from the downsampled image. Then, we present Center-Surround Pyramid Pooling (CSPP) that explicitly propagates the context features from the surrounding context image patch to the inner center image patch. Finally, we use the matting module which takes the image, trimap and context features to estimate the alpha matte. Experimental results demonstrate that the proposed method performs favorably against the state-of-the-art methods on the AlphaMatting and Adobe Image Matting datasets.

description: Purpose: The purpose is to compare the effectiveness of Sub-Tenon’s anaesthesia versus Peribulbar anaesthesia for intraoperative analgesia and ocular akinesia during phacoemulsification surgery. Material And Method: This analytic study consisted of 100 patients with simple random sampling, 50 patients in each group. Patients in group A had phacoemulsification under subtenon anaesthesia and patients in group B had the same surgery under peribulbar anaesthesia. Their eye movements and pain during surgery were documented and analyzed .Pearson Chi square test was used to determine the statistical significance. Results: In the group A (Subtenon group) there are 35 (70%) males and in group B (peribulbar group) there were 26 (52%) males. The age range of the patients was between 50-70 years. Pain during surgery in group A is 3 (24%) whereas in group B it is 28 (56%).Eye movements during the procedure of subtenon anesthesia in group A is 13 (26%) whereas eye movements during peribulbar anesthesia in group B is 22 (44%). Chi-square test is used between the eye movements and pain of group A and group B. There p values are less than 0.005 which are significant. Conclusion: Sub-Tenon anaesthesia gains our full recommendation for prospective benefits and elimination of potential fatal hazards like globe perforation, retrobulbar hemorrhage, sub arachnoid injection, imposed by using sharp needle blocks. It calms patient’s fear of sharp needles which raises the anxiety levels even prior to surgery. This technique also provides almost immediate progressive surgery

description: We propose a new reinforcement learning algorithm for partially observable Markov decision processes (POMDP) based on spectral decomposition methods. While spectral methods have been previously employed for consistent learning of (passive) latent variable models such as hidden Markov models, POMDPs are more challenging since the learner interacts with the environment and possibly changes the future observations in the process. We devise a learning algorithm running through epochs, in each epoch we employ spectral techniques to learn the POMDP parameters from a trajectory generated by a fixed policy. At the end of the epoch, an optimization oracle returns the optimal memoryless planning policy which maximizes the expected reward based on the estimated POMDP model. We prove an order-optimal regret bound with respect to the optimal memoryless policy and efficient scaling with respect to the dimensionality of observation and action spaces.

King and Crown: an examination of the legal foundation of the British king

Subjects: Other education not elsewhere classified

description: 'The Crown' has been described as a 'term of art' in constitutional law. This is more than misleading, obscuring the pivotal legal position of the king, which in modern times has been conveniently ignored by lawyers and politicians alike. -- This work examines the legal processes by which a king is made, tracing those processes from the earliest times to the present day. It concludes that the king is made by the selection and recognition by the people, his taking of the Oath of Governance, and his subsequent anointing. (The religious aspects of the making of the king, though of considerable legal significance, are not examined herein, because of space constraints.) -- The Oath of Governance is conventionally called the 'Coronation Oath'-which terminology, while correctly categorising the Oath by reference to the occasion on which it is usually taken, has led by subliminal implication to an erroneous conclusion by many modern commentators that the Oath is merely ceremonial. -- This work highlights the legal implications of the king's Oath of Governance throughout history, particularly in times of political unrest, and concludes that the Oath legally :- conveys power from the people to the person about to become king (the willingness of the people so to confer the power having been evidenced in their collective recognition of that person); - bestows all the prerogatives of the office of king upon that person; - enshrines the manner in which those prerogatives are to be exercised by the king in his people(s)' governance; and that therefore the Oath of Governance is the foundation of the British Constitution. -- All power and prerogative lie with the king, who as a result of his Oath of Governance is sworn to maintain the peace and protection of his people(s), and the king can not, in conscience or law, either do, or allow, anything that is in opposition to the terms of that Oath.

description: Uveitis comprehends a wide and heterogeneous group of intraocular inflammatory conditions potentially sight-threatening and variable therapeutic strategies have been proposed. Classical treatment with steroids and Zonventional immunosuppressive agents is often used as first-step. However, a number of patients may not respond properly or tolerate these medications with well-known side effects. Over the last two decades, advances in the understanding of the pathogenesis of autoimmune uveitis, as well as improved biotechnology, have enabled the development of a new class of drugs called biologics, which provide selective targeting of the immune mediators of the inflammation cascade. Biologic therapies were introduced as a new option for patients with autoimmune rheumatic conditions refractory to conventional therapy and due to their success have posteriorly been used in ophthalmology to treat ocular inflammatory disorders. These new agents may potentially provide more effective and less toxic treatment than conventional therapy. Biologic therapies include a wide variety of drugs with different mechanisms of action, including monoclonal antibodies against cell surface markers, cytokines and their receptors, or recombinant forms of natural inhibitory molecules. Although some results are based on investigations with insufficient clinical trials, the majority of biologics indicate preferable outcomes on refractory uveitis, with remarkable promise to increase the possibility of long-term remission. The development of these new drugs is one of the most revolutionary advances in recent years, and the promise of shifting paradigms makes it an exciting time for uveitis specialists worldwide.

description: In this article we prove, under some geometrical condition on geodesic flow, exponential stabilization of wave equation with Zaremba boundary condition. We prove an estimate on the resolvent of semigroup associated with wave equation on the imaginary axis and we deduce the stabilization result. To prove this estimate we apply semiclassical measure technics. The main difficulties are to prove that support of measure is in characteristic set in a neighborhood of the jump in the boundary condition and to prove results of propagation in a neighborhood of a boundary point where Neumann boundary condition is imposed. In fact if a lot of results applied here are proved in previous articles, these two points are new.

Military robots: mapping the moral landscape

description: Military robots known as 'unmanned systems' now form a critical part of military force structures around the globe and have become the weapon of choice for the United States military. Their use and effect is now the subject of a wide-ranging international conversation. Drawing predominately on a contractual account of just war theory, this book examines the ethics and politics of unmanned warfare. It starts by examining the historical context of unmanned systems use and their increasingly autonomous nature and design. It then explores the practical and moral justifications thereof, which are underpinned by a military-state contract that governs the relationship between citizen, state and military force. Following this is a defence of the principles that inform the analysis of the many problems associated with drone usage, from technical limitations and psychological effects, through to matters of fairness and responsibility. In each case, as the West turns toward robotics in order to enhance its defensive measures, we see the systematic transfer of risk between combatants and, more concerningly, to noncombatants. Military Robots: Mapping the Moral Landscape postulates that focusing attention on the human element in these risk transfers and understanding that robotic systems may need to play a much more limited combat role than often thought, will be critical to ensuring that our moral and strategic objectives are honoured as we progress into the twenty-first century and a technology saturated battlespace -- abstract.

description: Given a fixed $α\in (0,1)$, we study the inverse problem of recovering the isometry class of a smooth closed and connected Riemannian manifold $(M,g)$, given the knowledge of a source-to-solution map for the fractional Laplace equation $(-Δ_g)^αu=f$ on the manifold subject to an arbitrarily small observation region $\mathcal O$ where sources can be placed and solutions can be measured. This can be viewed as a non-local analogue of the well known anisotropic Calderón problem that is concerned with the limiting case $α=1$. While the latter problem is widely open in dimensions three and higher, we solve the non-local problem in broad geometric generality, assuming only a local property on the a priori known observation region $\mathcal O$ while making no geometric assumptions on the inaccessible region of the manifold, namely $M\setminus \mathcal O$. Our proof is based on discovering a hidden connection to a variant of Carlson's theorem in complex analysis that allows us to reduce the non-local inverse problem to the Gel'fand inverse spectral problem.

Quantum transport and switching in long-range coupled quantum systems

Publisher: name: Macquarie University

description: Controlling the dynamics of quantum states is a common demand in quantum technology. We theoretically study quantum transport and switching in long-range coupled quantum networks possessing a single excitation. The qubit networks of our study are affected by Markovian environments while one qubit is irreversibly connected to an additional site. Different goals are studied towards controlling quantum transport such as efficient single excitation transfer, switching quantum transport,and manipulating the quantum states of qubit networks. These goals have been previously investigated using different mechanisms, however in this thesis we approach them by proposing appropriate geometrical arrangements of sites. Regarding efficient single excitation transfer we follow two approaches: Checking if there exist a spatial dimension preference for qubit arrangements towards optimal quantum transport, and whether the efficient network designs are robust against geometrical variations. For dimension analysis a random walk optimization method is used to compare the transport efficiency of networks expanded in one and two spatial dimensions. We find that for some choices of network parameters the two-dimensional networks are slightly more efficient than the one dimensional equivalent networks. This assures that designing one-dimensional qubit channels are adequate for efficient transport and the two-dimensional networks should only be considered where the two-dimensional spatial expansion is more compatible with the surrounding architecture. To design a network, after deciding about the network dimensionality, one may attempt to optimize the channel geometry which might result in a non-robust optimal configuration against the geometrical errors. To achieve robust optimal configurations we follow two approaches: We investigate the efficient configurations of sites in both one and two dimensional arrangements and present some patterns of robust geometric arrangements of sites in geometrical parameter space. Another approach to achieve robust efficient transport is defining a quantity as the geometrical robustness (georobustness) of qubit networks. By optimising geo-robustness against the network-environment parameters one can efficiently transfer a single excitation with many arbitrary arrangements of the network sites. Switching of quantum states is another goal towards controlled quantum dynamics. We study the transport characteristics of highly symmetric three-dimensional networks and analytically prove that a fraction of the initially injected excitation can trap for long durations via the creation of dark states. Using this characteristic we suggest switching devices which are robust against environmental noises.

description: MicroRNA dysregulation is a common feature of cancer and due to the promiscuity of microRNA binding this can result in a wide array of genes whose expression is altered. miR-106b is an oncomiR overexpressed in cholangiocarcinoma and its upregulation in this and other cancers often leads to repression of anti-tumorigenic targets. The goal of this study was to identify the miR-106b-regulated gene landscape in cholangiocarcinoma cells using a genome-wide, unbiased mRNA analysis. Through RNA-Seq we found 112 mRNAs significantly repressed by miR-106b. The majority of these genes contain the specific miR-106b seed-binding site. We have validated 11 genes from this set at the mRNA level and demonstrated regulation by miR-106b of 7 proteins. Combined analysis of our miR-106b-regulated mRNA data set plus published reports indicate that miR-106b binding is anchored by G:C pairing in and near the seed. Novel targets Kruppel-like factor 2 (KLF2) and KLF6 were verified both at the mRNA and at the protein level. Further investigation showed regulation of four other KLF family members by miR-106b. We have discovered coordinated repression of multiple members of the KLF family by miR-106b that may play a role in cholangiocarcinoma tumor biology.

description: An alternative to Density Functional Theory are wavefunction based electronic structure calculations for solids. In order to perform them the Exponential Wall (EW) problem has to be resolved. It is caused by an exponential increase of the number of configurations with increasing electron number N. There are different routes one may follow. One is to characterize a many-electron wavefunction by a vector in Liouville space with a cumulant metric rather than in Hilbert space. This removes the EW problem. Another is to model the solid by an {\it impurity} or {\it fragment} embedded in a {\it bath} which is treated at a much lower level than the former. This is the case in Density Matrix Embedding Theory (DMET) or Density Embedding Theory (DET). The latter are closely related to a Schmidt decomposition of a system and to the determination of the associated entanglement. We show here the connection between the two approaches. It turns out that the DMET (or DET) has an identical active space as a previously used Local Ansatz, based on a projection and partitioning approach. Yet, the EW problem is resolved differently in the two cases. By studying a $H_{10}$ ring these differences are analyzed with the help of the method of increments.

description: The evaluation of acute poisoning is challenging due to varied toxic substances and clinical presentations. The new-Poisoning Mortality Score was recently developed to assess patients with acute poisoning and showed good performance in predicting in-hospital mortality. The objective of this study is to externally validate the performance of the new-Poisoning Mortality Score and to compare it with the Modified Early Warning Score. This retrospective analysis used data from the 2019–2020 Injury Surveillance Cohort, established by the Korea Center for Disease Control and Prevention, to perform external validation of the new-Poisoning Mortality Score. The statistical performances of the new-Poisoning Mortality and Modified Early Warning Scores were assessed and compared in terms of discrimination and calibration. Discrimination analysis involved metrics such as sensitivity, specificity, accuracy, and the area under the receiver operating characteristic curve. For calibration analysis, the Hosmer-Lemeshow goodness-of-fit test was utilized and calibration curves for each score were generated to elucidate the relationship between observed and predicted mortalities. This study analysed 16,570 patients with acute poisoning. Significant differences were observed between survivors and those who died in-hospital, including age, sex, and vital signs. The new-Poisoning Mortality Score showed better performance over the Modified Early Warning Score in predicting in-hospital mortality, in terms of the area under the receiver operating characteristic curve (0.947 versus 0.800), sensitivity (0.863 versus 0.667), specificity (0.912 versus 0.817), and accuracy (0.911 versus 0.814). When evaluated through calibration curves, the new-Poisoning Mortality Score showed better concordance between predicted and observed mortalities. In subgroup analyses, the score system consistently showed strong performance, excelling particularly in substances with high mortality indices and remaining superior in all substances as a group. Our study has helped to validate the new-Poisoning Mortality Score as an effective tool for predicting in-hospital mortality in patients with acute poisoning in the emergency department. The score system demonstrated superior performance over the Modified Early Warning Score in various metrics. Our findings suggest that the new-Poisoning Mortality Score can contribute to the enhancement of clinical decision-making and patient management.
On the number of high-dimensional partitions

description: Let $P_{d}(n)$ denote the number of $n \times \ldots \times n$ $d$-dimensional partitions with entries from $\left\{0,1,\ldots,n\right\}$. Building upon the works of Balogh-Treglown-Wagner and Noel-Scott-Sudakov, we show that when $d \to \infty$, $$P_{d}(n) = 2^{(1+o_{d}(1)) \sqrt{\frac{6}{(d+1)π}} \cdot n^{d}}$$ holds for all $n \geq 1$. This makes progress towards a conjecture of Moshkovitz-Shapira [{\it{Adv. in Math.}} 262 (2014), 1107--1129]. Via the main result of Moshkovitz and Shapira, our estimate also determines asymptotically a Ramsey theoretic parameter related to Erdős-Szekeres-type functions, thus solving a problem of Fox, Pach, Sudakov, and Suk [{\it{Proc. Lond. Math. Soc.}} 105 (2012), 953--982]. Our main result is a new supersaturation theorem for antichains in $[n]^{d}$, which may be of independent interest.

description: This article addresses the three-dimensional open-dimension rectangular packing problem (3D-ODRPP), which aims to pack a given set of unequal-size rectangular boxes within an enveloping rectangular space such that the volume of the occupied space is minimized. Even though the studied 3D-ODRPP is NP hard, the development of sophisticated global optimization methods has been stimulated. The mathematical programming formulation for the 3D-ODRPP has evolved into an effective and efficient mixed-integer linear programming (MILP) model. This study proposes an advanced exact scheme yielding a guaranteed global optimal solution given that all the instance data are non-negative rational numbers. The developed MILP retains not only fewer variables but also fewer constraints than the state-of-the-art models. The superior effectiveness and efficiency of the developed scheme are demonstrated with numerical experiments, where two sets of benchmark instances from references, real-world instances and instances with rational data are included.

description: The combination of the surface science techniques (STM, XPS, ARPES) and density-functional theory calculations was used to study the decoupling of graphene from Ni(111) by oxygen intercalation. The formation of the antiferromagnetic (AFM) NiO layer at the interface between graphene and ferromagnetic (FM) Ni is found, where graphene protects the underlying AFM/FM sandwich system. It is found that graphene is fully decoupled in this system and strongly $p$-doped via charge transfer with a position of the Dirac point of $(0.69\pm0.02)$ eV above the Fermi level. Our theoretical analysis confirms all experimental findings, addressing also the interface properties between graphene and AFM NiO.

description: We extend the entanglement bootstrap approach to (3+1)-dimensions. We study knotted excitations of (3+1)-dimensional liquid topological orders and exotic fusion processes of loops. As in previous work in (2+1)-dimensions, we define a variety of superselection sectors and fusion spaces from two axioms on the ground state entanglement entropy. In particular, we identify fusion spaces associated with knots. We generalize the information convex set to a new class of regions called immersed regions, promoting various theorems to this new context. Examples from solvable models are provided; for instance, a concrete calculation of knot multiplicity shows that the knot complement of a trefoil knot can store quantum information. We define spiral maps that allow us to understand consistency relations for torus knots as well as spiral fusions of fluxes.

Long term associations and serial recall: using synaesthesia to probe memory for sequences

description: In our daily lives, we constantly have to remember sequences such as telephone numbers, license plates or pin codes. How do we hold and recall information that is presented in a sequential manner? Recent interest in the field of serial recall has highlighted that long-term memory seems to interact with our ability to accurately recall sequences. In this thesis, I examine this interaction using overlearnt sequences of digits and letters, and by testing an unusual group with extremely consistent long-term links between digits and colours : synaesthetes. Fror grapheme-colour synaesthetes, letters and digits elicit vivid perceptions of colours. As grapheme-colour pairings are different between synaesthetes but highly consistent for each individual, synaesthesia offers a unique opportunity to examine the effect of long-term associations on immediate serial recall. A recent study suggests that serial colour memory in synaesthetes is not generally enhanced but that synaesthetic associations can, under certain circumstances, be used strategically to improve colour memory. By further exploring this link, we may gain a more detailed insight into the time course of backward translation between colours and digits in synaesthetes and are at the same time able to examine the effect of long-term knowledge on Immediate Serial Recall (ISR) of colours.
