PML nuclear bodies and the spatial analysis of interphase mammalian cell nuclear architecture
Creators: name: Batty, Elizabeth
Publisher: name: Imperial College London
Year: 2009

description: Promyelocytic leukaemia nuclear bodies (PML NBs) are found within the nucleus of mammalian cells. Numbering between 10 and 30 per nucleus, they are an obvious feature of the nuclear landscape, yet their functions have still to be unambiguously defined. In the mammalian nucleus, compartmentalization of functions is apparent, as reflected in the wide-range of other nuclear compartments that can be identified. Quantification of relationships between PML NBs and other nuclear functional compartments is essential for a complete understanding of PML NB function. Initially, PML size, number, distance relationships, and spatial organisation in relation to each other, and the nuclear boundary and centroid, under the spatial point pattern theory hypothesis of Complete Spatial Randomness (CSR), were investigated in both normal and SV40 transformed MRC5 and WI38 human foetal lung fibroblasts. This was also completed in normal MRC5 cells treated with heat shock, and interferon β (both of which alter PML NB morphometrics), and also serum starvation. PML NBs appeared to locate according to CSR with respect to each other, and inter – PML distances were dependent upon median PML NB number per nucleus. PML NBs did not tend to associate with the nuclear centroid, and were repelled from the nuclear boundary in all cell lines and conditions. The distance and spatial organisation relationships between PML NBs and eleven different nuclear compartments were also compared and contrasted in the cell lines and conditions mentioned previously. PML NBs were shown to share strong distance and spatial organisation relationships with the 11S immunoproteasome regulator, SC35 domains, and transcriptional compartments in normal asynchronous nuclei, and with telomeres in transformed cells, highlighting likely functions for the bodies. Lastly, the three dimensional spatial preference of functional compartments in the nucleus was determined using an aggregate map, which provided a novel means to visualise the nuclear location of functional compartments in relation to each other, and under different cellular conditions. Spatial preference fell into four categories: 1) diffuse, 2) annular, 3) core, and 4) polar. Nucleoli and RNA polymerase maintained their spatial preference across cell lines and conditions, whereas other compartments showed altered spatial preferences. Interestingly, viral transformation led to global disorganisation of the nucleus, where most compartments (including PML NBs) reverted to a diffuse spatial preference.

description: Ozone pollution appears as a major air quality issue, e.g. for the protection of human health and vegetation. Formation of ground level ozone is a complex photochemical phenomenon and involves numerous intricate factors most of which are interrelated with each other. Machine learning techniques can be adopted to predict the ground level ozone. The main objective of the present study is to develop the state-of-the-art ensemble bagging approach to model the summer time ground level ozone in an industrial area comprising a hazardous waste management facility. In this study, the feasibility of using ensemble model with seven meteorological parameters as input variables to predict the surface level O3 concentration. Multilayer perceptron, RTree, REPTree, and Random forest were employed as the base learners. The error measures used for checking the performance of each model includes IoAd, R2, and PEP. The model results were validated against an independent test data set. Bagged random forest predicted the ground level ozone better with higher Nash-Sutcliffe coefficient 0.93. This study scaffolded the current research gap in big data analysis identified with air pollutant prediction. Implications: The main focus of this paper is to model the summer time ground level O3 concentration in an Industrial area comprising of hazardous waste management facility. Comparison study was made between the base classifiers and the ensemble classifiers. Most of the conventional models can well predict the average concentrations. In this case the peak concentrations are of importance as it has serious effect on human health and environment. The models developed should also be homoscedastic.
The role of surface properties in the high shear granulation of pharmaceuticals
Creators: name: Ho, Raimundo
Publisher: name: Imperial College London
Year: 2009

description: This thesis presents a detailed study into the role of surface chemistry in the high shear granulation of organic pharmaceutical solids. Crystalline materials with markedly different surface chemistries were selected as model compounds which were granulated with a polymeric binder. The surface wettability of primary powders was evaluated by employing the sessile drop contact angle measurements to evaluate the facet-specific surface energetics of macroscopic crystals, obtained via a solvent-mediated or a temperature-controlled crystallisation technique. A novel methodology using inverse gas chromatography (IGC) at finite concentrations (FC) was developed to evaluate surface energy distributions of the powder samples. The surface energetics of organic macroscopic crystals was found to be facet-specific, consistent with the local surface chemistry of the facet under examination. The rank order of hydrophilicity of specific facet was in good agreement with concentration of hydroxyl groups determined from X-ray photoelectron spectroscopy. IGC-FC was applied to measure [gamma]d/SV profile, which were in good agreement with the [gamma]d/SV values measured from contact angle on the corresponding single crystals. This technique was shown to be able to distinguish surface energy heterogeneity, homogeneity as well as subtle changes in the [gamma]d/SV distributions, due to variations in the crystal habits. The wettability of the model compounds was ranked based on the contact angle polarity and IGC surface energy heterogeneity distributions, and the spreadability of binder solution was assessed based on the thermodynamic spreading coefficients. The increase in surface wettability led to the increase in granule mean size and granule strength. Formulations with similar wetting behaviour resulted in similar granule size, whilst those formulations with dissimilar surface wettability were found to exhibit substantially different granulation behaviour. In conclusion, the materials surface chemistry plays a crucial role in granulation processes. Its thorough characterisation and understanding may lead to more controllable product attributes and improved final performances.

description: Quantum complexity has already shed light on CFT states dual to bulk geometries containing spacelike singularities \cite{Barbon:2015ria, Bolognesi:2018ion, Caputa:2021pad}. In this work, we turn our attention to quantum complexity of CFT/quantum gravity states dual to bulk geometries with a naked timelike singularity. The appearance of naked timelike singularities in semiclassical gravity is allowed in string theory, particularly in the context of holography, so long as they satisfy the \emph{Gubser criterion} \cite{Gubser:2000nd, Gursoy:2008za}. In this work, we use holographic complexity as a probe on geometries containing naked timelike singularities and explore potential relation to the Gubser criterion for detecting allowable naked timelike singularities. We study three specific cases, namely the negative mass Schwarzschild-AdS spacetime, the timelike Kasner-AdS \cite{Ren:2016xhb} and Einstein-dilaton system \cite{Ren:2019lgw}. The first two cases are outright ruled out by the Gubser criterion while the third case is more subtle - according to the Gubser criterion the singularity switches from forbidden to admissible as the parameter $α$ is dialed in the range $[0,1]$ across the transition point at $α= 1/\sqrt{3}$. We probe all three geometries using two holographic complexity prescriptions, namely CA and CV. For the case of the negative mass SAdS and timelike Kasner-AdS$_4$ the complexities display no sign of pathology (both receive finite contribution from the naked singularity). For the Einstein-Dilaton case, action-complexity does display a sharp transition from physical positive values to patholgical negative divergent values (arising from the singularity) as one transcends the Gubser bound. Our study suggests that neither action-complexity (CA) nor volume-complexity (CV) can serve as a sensitive tool to investigate (naked) timelike singularities.

Characterisation of ADAMTS-4 endocytosis by chondrosarcoma cells and chondrocytes
Creators: name: Owen, Kathryn
Publisher: name: Imperial College London
Year: 2009

description: Aggrecan is one of the most abundant components of the articular cartilage matrix and its degradation by aggrecanases is considered to be a key early event in the development of osteoarthritis. This study investigates whether the extracellular level of ADAMTS-4 (a disintegrin and metalloproteinase with thrombospondin type 1 motifs-4), one of the most studied aggrecanases, can be regulated by receptor-mediated endocytosis. Exogenously-added ADAMTS-4 disappeared from the medium of HTB94 cells and TCA-soluble degradation products of ADAMTS-4 increased in the medium over time. Fluorescent-labeled ADAMTS-4 could be detected within the cell by confocal microscopy. ADAMTS-4 clearance by HTB94 cells and chondrocytes could be inhibited by more than 70 % by heparin and another sulfated glycan, calcium pentosan polysulfate, suggesting that the cellular uptake of ADAMTS-4 was via a mechanism involving cell surface heparan sulfate proteoglycans (HSPGs). GM6001 also inhibited ADAMTS-4 clearance by 50 %, suggesting that cell surface metalloprotease-mediated degradation played a contributory role. However, ADAMTS-4 clearance was reduced by 50 % in a HSPG-deficient cell line compared to wild-type cells, further supporting a HSPG-dependent mechanism of ADAMTS-4 cellular uptake and preliminary studies using Timp-3-null fibroblasts suggest that ADAMTS-4 may be endocytosed in a complex with TIMP-3. In HTB94 cells and chondrocytes, the appearance of TCA-soluble degradation products was also inhibited by at least 50 % by receptor-associated protein (RAP), an antagonist for members of the low-density lipoprotein receptor (LDL-R) family. However, siRNA knockdown of LDL-receptor-related protein (LRP-1), a member of the LDL-R family, in HTB94 cells and the use of an LRP-1-deficient cell line had no affect on the clearance of ADAMTS-4. These results suggest that another member of the LDL-R family may be involved. Taken together, this research has revealed a novel RAP-sensitive and/or HSPG-sensitive mechanism of ADAMTS-4 regulation which may have a role in the degradation of the cartilage matrix.

description: The artificial intelligence (AI) system designer for thermal comfort faces insufficient data recorded from the current user or overfitting due to unreliable training data. This work introduces the reliable data set for training the AI subsystem for thermal comfort. This paper presents the control algorithm based on shallow supervised learning, which is simple enough to be implemented in the Internet of Things (IoT) system for residential usage using ASHRAE RP-884 and ASHRAE Global Thermal Comfort Database II. No training data for thermal comfort is available as reliable as this dataset, but the direct use of this data can lead to overfitting. This work offers the algorithm for data filtering and semantic data augmentation for the ASHRAE database for the supervised learning process. Overfitting always becomes a problem due to the psychological aspect involved in the thermal comfort decision. The method to check the AI system based on the psychrometric chart against overfitting is presented. This paper also assesses the most important parameters needed to achieve human thermal comfort. This method can support the development of reinforced learning for thermal comfort.

Transient optical studies of photoinduced charge transfer in semiconductor quantum dot solar cells
Creators: name: Leventis, Henry C.
Publisher: name: Imperial College London
Year: 2009

description: Semiconductor quantum dots (also referred to as 'nanocrystals‘) are well suited as light-harvesting agents in solar cells because they are robust, have tuneable effective band gaps, and are easy to process. The research presented in this thesis is targeted towards the study of excitonic solar cells employing semiconductor nanocrystals as a light harvesting component. Gaining control of the interfacial charge transfer processes in operation in these devices forms a crucial part of any attempt to optimise their performance. In particular, the use of transient spectroscopic techniques reveals how efficient and long-lived charge separation can be achieved in these solar cell architectures. The primary focus of this research is to investigate the parameters influencing charge transfer in dye-sensitised solar cells (DSSCs) using colloidal quantum dots as light-absorbers. One aim is to study the impact of varying the thermodynamic driving forces provided for interfacial electron transfer on the yield of both the electron injection and hole regeneration reactions occurring within the DSSC; this can be achieved by varying the energetics of each component of the system (metal oxide, quantum dot and hole conductor) in turn. In addition, the interfacial morphology can be modulated by changing the passivating ligands present at the QD surface, and by modifying the structure of the redox mediator (or hole conductor). In doing so, we also attempt to improve our understanding of how charge carrier trapping in quantum dots impacts upon solar cell performance. Furthermore, new strategies towards solar cell design are presented, which show great potential as a result of their favourable photophysical properties. One of these approaches (presented in the final chapter) is to effect the in situ growth of CdS nanocrystals in a conducting polymer, a method which circumvents many of the processing issues associated with the use of nanocrystals in polymer blend solar cell architectures. It is hoped that the work presented in this thesis is used to develop design rules for the construction of semiconductor nanocrystal-based excitonic solar cells. By identifying which key parameters control the rates and yields of electron transfer at the nanocrystal interface, improvements in device efficiency can be realised. It is believed that these studies fill an important gap in our current understanding, and highlight some of the potential benefits and shortcomings of using semiconductor nanocrystals in cheap, solution-processed solar cells.

description: The flow of an electrically conducting fluid driven by a traveling magnetic field imposed at the endcaps of a cylindrical annulus is numerically studied. At sufficiently large magnetic Reynolds number, the system undergoes a transition from synchronism with the traveling field to a stalled flow, similar to the one observed in electromagnetic pumps. A new type of boundary layer is identified for such electromagnetically-driven flows, that can be understood as a combination of Hartmann and Shercliff layers generated by the spatio-temporal variations of the magnetic field imposed at the boundaries. An energy budget calculation shows that energy dissipation mostly occurs within these boundary layers and we observe that the ohmic dissipation Db always overcomes the viscous dissipation Dv, suggesting the existence of an upper bound for the efficiency of electromagnetic pumps. Finally, we show that the destabilization of the flow occurs when both dissipations are nearly equal.

description: This paper is a sequel to one in which we examined the affine symmetry algebras of arbitrary classical principal chiral models and symmetric space models in two dimensions. It examines the extension of those results in the presence of gravity. The main result is that even though the symmetry transformations of the fields depend on the gravitational background, the symmetry algebras of these classical theories are completely unchanged by the presence of arbitrary gravitational backgrounds. On the other hand, we are unable to generalize the Virasoro symmetries of the flat-space theories to theories with gravity.

description: Quantum computers have made extraordinary progress over the past decade, and significant milestones have been achieved along the path of pursuing universal fault-tolerant quantum computers. Quantum advantage, the tipping point heralding the quantum era, has been accomplished along with several waves of breakthroughs. Quantum hardware has become more integrated and architectural compared to its toddler days. The controlling precision of various physical systems is pushed beyond the fault-tolerant threshold. Meanwhile, quantum computation research has established a new norm by embracing industrialization and commercialization. The joint power of governments, private investors, and tech companies has significantly shaped a new vibrant environment that accelerates the development of this field, now at the beginning of the noisy intermediate-scale quantum era. Here, we first discuss the progress achieved in the field of quantum computation by reviewing the most important algorithms and advances in the most promising technical routes, and then summarizing the next-stage challenges. Furthermore, we illustrate our confidence that solid foundations have been built for the fault-tolerant quantum computer and our optimism that the emergence of quantum killer applications essential for human society shall happen in the future.

description: PSR B0943+10 is an old non-recycled pulsar which for decades has been mostly known for its rapid and spontaneous radio mode switching. Recently, Hermsen et al. (2013) discovered correlated changes in the thermal X-ray emission from the polar cap, thus demonstrating that radio modes are not just a product of the local changes in the radio emission region, but a sign of some global magnetospheric transformation. At about the same time, owing to the commissioning of the new generation of low-frequency radio arrays, the broadband observations at the lowest edge of ionospheric transparency window became available. At these radio frequencies profile morphology and the single-pulse properties of PSR B0943+10's emission become very dynamic, providing details not only about the emission itself, but also about the conditions in the polar gap. Here, I will present the recent results of the LOFAR observations of PSR B0943+10 and discuss their contribution to the multiwavelength picture.

Datapath and memory co-optimization for FPGA-based computation
Creators: name: Turkington, Kieron
Publisher: name: Imperial College London
Year: 2010

description: With the large resource densities available on modern FPGAs it is often the available memory bandwidth that limits the parallelism (and therefore performance) that can be achieved. For this reason the focus of this thesis is the development of an integrated scheduling and memory optimisation methodology to allow high levels of parallelism to be exploited in FPGA based designs. A manual translation from C to hardware is first investigated as a case study, exposing a number of potential optimisation techniques that have not been exploited in existing work. An existing outer loop pipelining approach, originally developed for VLIW processors, is extended and adapted for application to FPGAs. The outer loop pipelining methodology is first developed to use a fixed memory subsystem design and then extended to automate the optimisation of the memory subsystem. This approach allocates arrays to physical memories and selects the set of data reuse structures to implement to match the available and required memory bandwidths as the pipelining search progresses. The final extension to this work is to include the partitioning of data from a single array across multiple physical memories, increasing the number of memory ports through which data my be accessed. The facility for loop unrolling is also added to increase the potential for parallelism and exploit the additional bandwidth that partitioning can provide. We describe our approach based on formal methodologies and present the results achieved when these methods are applied to a number of benchmarks. These results show the advantages of both extending pipelining to levels above the innermost loop and the co-optimisation of the datapath and memory subsystem.

Regulation of BCL6: p38 MAPK signalling and CTCF transcriptional regulation converge at exon 1
Creators: name: Batlle, Ana
Publisher: name: Imperial College London
Year: 2010

description: BCL6 is a zinc finger transcriptional repressor, which is highly expressed in germinal centre B-cells, and is essential for germinal centre formation and T-dependent antibody responses. Deregulated BCL6 expression is associated with certain non- Hodgkin’s lymphomas. High expression is observed in breast cancer. Tight lineage and temporal regulation of BCL6 is, therefore, required for normal immunity and abnormal regulation occurs in cancer. Regulatory mechanisms have been analysed in two settings. Firstly, BCL6 is strongly induced by the tyrosine kinase inhibitor, Imatinib, in chronic myeloid leukaemia lymphoid blast crisis cell lines, and this effect was used in order to study the effects of phospho-protein signalling on BCL6 expression and a major finding is that p38 MAPK induced BCL6. Also, p38 is, at least in part, responsible for BCL6 expression in basal conditions in the germinal centre representative Burkitt’s lymphoma cell lines and that qualitatively different CD40 stimuli can either induce or repress BCL6 expression. Luciferase assays showed that p38 acts at a 300bp sequence immediately 5’ of exon 1, and probably also at more distal sequences. Overall it appears that the balance between positive and negative regulatory controls BCL6 expression with inhibitory signalling pathways being predominant in most circumstances. Focusing on BCL6 exon 1, a binding site for the multifunctional regulator CTCF was identified. CTCF interacts in vitro and in vivo with this sequence. Reduced expression of CTCF in germinal centre cells caused a moderate reduction of BCL6 expression. Finally, although no clear differences were observed in the methylation status of the CTCF binding site on exon 1, a significant enrichment of active histone modifications at this site was observed in BCL6 expressing cells, suggesting that CTCF may have a role in the epigenetic regulation of BCL6.

description: The article is a natural continuation of our paper {\em Quantum scalar field in FRW Universe with constant electromagnetic background}, Int. J. Mod. Phys. {\bf A12}, 4837 (1997). We generalize the latter consideration to the case of massive spinor field, which is placed in FRW Universe of special type with a constant electromagnetic field. To this end special sets of exact solutions of Dirac equation in the background under consideration are constructed and classified. Using these solutions representations for out-in, in-in, and out-out spinor Green functions are explicitly constructed as proper-time integrals over the corresponding contours in complex proper-time plane. The vacuum-to-vacuum transition amplitude and number of created particles are found and vacuum instability is discussed. The mean values of the current and energy-momentum tensor are evaluated, and different approximations for them are presented. The back reaction related to particle creation and to the polarization of the unstable vacuum is estimated in different regimes.

description: It is often claimed that Bayesian methods, in particular Bayes factor methods for hypothesis testing, can deal with optional stopping. We first give an overview, using elementary probability theory, of three different mathematical meanings that various authors give to this claim: (1) stopping rule independence, (2) posterior calibration and (3) (semi-) frequentist robustness to optional stopping. We then prove theorems to the effect that these claims do indeed hold in a general measure-theoretic setting. For claims of type (2) and (3), such results are new. By allowing for non-integrable measures based on improper priors, we obtain particularly strong results for the practically important case of models with nuisance parameters satisfying a group invariance (such as location or scale). We also discuss the practical relevance of (1)--(3), and conclude that whether Bayes factor methods actually perform well under optional stopping crucially depends on details of models, priors and the goal of the analysis.

description: Switching model with one predator and two prey species is considered. The prey species have the ability of group defence. Therefore, the predator will be attracted towards that habitat where prey are less in number. The stability analysis is carried out for two equilibrium values. The theoretical results are compared with the numerical results for a set of values. The Hopf bifuracation analysis is done to support the stability results.
ReachMAN to help sub-acute patients training reaching and manipulation
Creators: name: Yeong, Che Fai

description: Conventional rehabilitation after stroke, consisting in one-to-one practice with the therapist, is labor-intensive and subjective. Furthermore, there is evidence that increasing training would benefit the motor function of stroke survivors, though the available resources do not allow it. Training with dedicated robotic devices promises to address these problems and to promote motivation through therapeutic games. The goal of this project is to develop a simple robotic system to assist rehabilitation that could easily be integrated in existing hospital environments and rehabilitation centers. A study was first carried out to analyze the kinematics of hand movements while performing representative activities of daily living. Results showed that movements were confined to one plane so can be trained using a robot with less degrees-of-freedom (DOF). Hence ReachMAN, a compact 3 DOF robot based on an endpoint based approach, was developed to train reaching, forearm pronosupination and grasping, independently or simultaneously. ReachMAN's exercises were developed using games based on software thereby facilitating active participation from patients. Visual, haptic and performance feedback were provided to increase motivation. Tuneable levels of difficulty were provided to suit patient's ability. A pilot study with three subjects was first conducted to evaluate the potential use of ReachMAN as a rehabilitation tool and to determine suitable settings for training. Following positive results from a pilot study, a clinical study was initiated to investigate the effect of rehabilitation using ReachMAN. Preliminary results of 6 subjects show an increase in patients upper limb motor activity, range of movements, smoothness and reduction in movement duration. Subjects reported to be motivated with the robot training and felt that the robot helped in their recovery. The results of this thesis suggest that a compact and simple robot such as ReachMAN can be used to enhance recovery in sub-acute stroke patients.

description: Salt River Project (SRP) proposes to construct a meteorological station with associated overhead electric and buried telephone lines at Zuni Salt Lake to monitor atmospheric conditions south of the Fence Lake Transportation Corridor. The Bureau of Land Management (BLM), Las Cruces District, Socorro Resource Area is the lead agency for cultural resources. The buried telephone line will extend from an existing buried line adjacent to NM State Route 32, 33 feet (10 m) to the station and the overhead electric line will extend from a pole at an existing overhead line to the south, 330 feet (100 m) to the station. SRP required a width of 100 feet (30 m) for the right-of-way (ROW) easement for the station and utility lines to allow for any construction impacts and any future modifications. SWCA, Inc. Environmental Consultants (SWCA), was contracted by Salt River Project to conduct a cultural resource survey of this portion of Site LA 31800 because this site has not been recorded in detail. Field work was conducted by SWCA archaeologist Richard A. Anduze on September 14 and December 14, 1994. The proposed project centerline was delineated with pink flagging tape by SRP Engineer Kenneth W. Rodgers, who accompanied Anduze in the field. An area of 1.75 acres was inventoried.

description: The town of Seguin in Guadalupe County, Texas, was known for its numerous limecrete structures. Limecrete structures probably once numbered more than I 00; now, the house known as Sebastopol is one of only two still standing. Between 1978 and 1988, archeological excavations were conducted by the Texas Parks and Wildlife Department in and around Sebastopol. The excavations were preparatory to and in conjunction with architectural restoration of the building and development of the site as a State Historical Park. Archeological excavations were intended to evaluate only those areas impacted by the architectural restoration. Excavation units were placed primarily in and around the building, but also around the cistern and in other yard areas. This report, prepared by Prewitt and Associates, Inc., summarizes the excavation seasons and provides analyses of ceramics from across the site as well as diagnostic artifacts from three rooms in the house. Artifacts range in age from the mid nineteenth century up to modem times and came from as far away as Europe and the Far East. Of 106,586 artifacts recovered by the Texas Parks and Wildlife Department, 4,071 artifacts are discussed here.

Motions of the String Solutions in the XXZ Spin Chain under a Varying Twist

description: We determine the motions of the roots of the Bethe ansatz equation for the ground state in the XXZ spin chain under a varying twist angle. This is done by analytic as well as numerical study at a finite size system. In the attractive critical regime $ 0< Δ<1 $, we reveal intriguing motions of strings due to the finite size corrections to the length of the strings: in the case of two-strings, the roots collide into the branch points perpendicularly to the imaginary axis, while in the case of three-strings, they fluctuate around the center of the string. These are successfully generalized to the case of $n$-string. These results are used to determine the final configuration of the momenta as well as that of the phase shift functions. We obtain these as well as the period and the Berry phase also in the regime $ Δ\leq -1$, establishing the continuity of the previous results at $ -1 < Δ< 0 $ to this regime. We argue that the Berry phase can be used as a measure of the statistics of the quasiparticle ( or the bound state) involved in the process.

description: Via partial resolution of Abelian orbifolds we present an algorithm for extracting a consistent set of gauge theory data for an arbitrary toric variety whose singularity a D-brane probes. As illustrative examples, we tabulate the matter content and superpotential for a D-brane living on the toric del Pezzo surfaces as well as the zeroth Hirzebruch surface. Moreover, we discuss the non-uniqueness of the general problem and present examples of vastly different theories whose moduli spaces are described by the same toric data. Our methods provide new tools for calculating gauge theories which flow to the same universality class in the IR. We shall call it ``Toric Duality.''

Reconnaissance / Survey

description: On August 27, 1982, Lyle M. Stone and James E. Ayres of Archaeological Research Services, Inc. (ARS) performed an archaeological survey of an approximately 128 acre parcel of land on the south side of the Salt River near Granite Reef Dam. The study area consists of U. S. Department of the Interior, Bureau of Land Management-administered land which has been withdrawn for U. S. Bureau of Reclamation purposes for use by the Salt River Project. Accordingly, this survey was performed under the authority and conditions of U. S. Department of the Interior Antiquities Permit Number 82-AZ-319 issued to ARS on June 30, 1982. This survey was requested by Salt River Project (SRP) in order to determine if cultural resources were located within the study area which would be affected by the proposed construction and operation of an interconnection between the Central Arizona Project (CAP) canal and the SRP water delivery system. The interconnection will include a turnout structure on the CAP canal and a pipeline or lined canal extending between the CAP canal and the Granite Reef Dam forebay and/or South Canal.
Engineering statistical transmutation of identical quantum particles

description: A fundamental pillar of quantum mechanics concerns indistinguishable quantum particles. In three dimensions they may be classified into fermions or bosons, having, respectively, antisymmetric or symmetric wave functions under particle exchange. One of numerous manifestations of this quantum statistics is the tendency of fermions (bosons) to anti-bunch (bunch). In a two-particle scattering experiment with two possible outgoing channels, the probability of the two particles to arrive each at a different terminal is enhanced (with respect to classical particles) for fermions, and reduced for bosons. Here we show that by entangling the particles with an external degree of freedom, we can engineer quantum statistical transmutation, e.g. causing fermions to bunch. Our analysis may have consequences on the observed fractional statistics of anyons, including non-Abelian statistics, with serious implications on quantum computing operations in the presence of external degrees of freedom.
