title: Data used in the paper "The minimum scale of grooving on a recently ruptured limestone fault"

description: There are two types of data presented: matlab structures and xyz files. We include two matlab structures of the results of our analysis, one for the Mt. Vettoretto fault and one for the Corona Heights fault. They have the following 9 fields: div_x: The length scale where parallel and perpendicular roughness in respect to the striations converge. This is also known as the minimum scale of grooving or the critical length scale, L<sub>c</sub>. div_y: The RMS height where parallel and perpendicular roughness converge. L1 and L2: The length scales in parallel and perpendicular directions. H1 and H2: The RMS height along the length scales in parallel and perpendicular directions. If L1 is in the parallel direction then H1 is also in the parallel direction. Z: The gridded topographic map that is used in the Monte Carlos RMS analysis to then calculate L1, L2, H1, and H2. dx: The spacing of the gridded data points in the gridded topographic map. FileName: The name of the original xyz scan for the Mt. Vettoretto data. For the Corona Heights data, the name of the files given to me by T. Candela. The xyz files presented are white light interferometer and structure from motion scans of the Mt. Vettoretto fault surface. They correspond to the "FileName" field of the MtVet_MinScaleRMS.mat file.

title: Glassy dynamics as seen by neutron Compton scattering: the case of amorphous alloy Zr40Be60.

description: The thermal stability and structure of binary amorphous Zr - Be alloys have been studied by us previously using differential scanning calorimetry and ND over a wide concentration range (30 &lt; x&lt;65). The studied amorphous system involved the composition range around the eutectic composition with boundary phases. It has been found that the crystallization of alloys with low beryllium contents (hypoeutectic alloys with x&lt;40) proceeds in two stages. At higher beryllium contents (hypereutectic alloys), one phase transition of the amorphous phase to a mixture of the alpha-Zr and ZrBe phases has been observed. This proposal seeks MANSE and neutron diffraction signs of thermal stability, vitrification and crystallisation of Zr40Be60 system by obtaining Zr and Be kinetic energies at temperatures T=1000 and 1200K below, 1600 at, and 1700K, above the crystalisation temperature.

title: 3D investigation of skyrmionic correlations in Cu2OSeO3.

description: Recent experimental findings in the cubic helimagnet Cu2OSeO3 highlight the paramount role of cubic anisotropy in stabilizing novel chiral and skyrmion phases. If a magnetic field is applied along the easy &lt;001&gt; crystallographic direction, competing cubic and exchange anisotropies tilt the wave vector of the conical spiral away from the magnetic field. Furthermore, thermodynamically stable or metastable skyrmions have been reported also at low temperatures. Our calculations show that the spatial orientation of these low temperature metastable skyrmion lattice is determined by magnetic anisotropies and the basis vectors of the skyrmion crystal are not necessarily orthogonal to the applied field. We now propose to investigate the spatial orientation of these low temperature skyrmions at using the unique capabilities of the ISIS 3D vector cryomagnet.

title: Northern Range Limit of Aphaenogaster picea in Maine 2015

description: Low temperatures at poleward range margins of terrestrial species tend to match cold tolerance limits, suggesting that range boundaries may be set by evolutionary constraints on cold physiology. The northeastern woodland ant, Aphaenogaster picea, occurs up to approximately 45 °N in central Maine. We combined presence-absence surveys with regression-tree analysis to characterize its northern range limit, and assayed two measures of cold tolerance operating on different time-scales to determine whether and how marginal populations adapt to environmental extremes. The boundary was predicted primarily by temperature, but low winter temperatures did not emerge as the primary correlate of species occurrence. Low summer temperatures and high seasonal variability predicted absence above the boundary, whereas high mean annual temperature (MAT) predicted presence in southern Maine. Locations between these zones formed an east-west band where presence was conditional on precipitation. In contrast, assays of cold tolerance across multiple sites indicated substantial local adaptation of cold tolerance at the range edge, with a 4-minute reduction in chill-coma recovery time across a 2-degree reduction in MAT. Baseline tolerance and capacity for additional plastic cold-hardening shifted in opposite directions, with hardening capacity approaching zero at the coldest sites. This trade-off suggests that populations at range edges may adapt to colder temperatures through genetic assimilation of plastic responses, potentially constraining further adaptation and range expansion.

title: Search for Kitaev spin liquid in K2IrO3

description: Majorana fermion, proposed by Ettore Majorana in 1937, is a putative elementary spin-1/2 particle that is its own antiparticle. In condensed-matter systems, analogs of Majorana fermions can be realized as quasiparticle excitations of a Kitaevs honeycomb lattice. The elusive Majorana fermions, the simplest possible non-Abelian anyons, have real-life implications for building a fault-free quantum computer. The newly reported copper iridate K2IrO3 is in a closer realization of Kitaev spin liquid than its predecessors A2IrO3 (A = Na, Li). The goal of this project is to provide an ultimate experimental proof of a Kitaev spin-liquid ground state. A combined zero- and longitudinal-field μSR study of the K2IrO3 will unravel fundamental insights into zero-field and field-induced spin dynamics characteristic of the magnetic Majorana excitations.

title: Doping effects in a S = 1/2 spin ladder system near quantum criticality

description: Spin ladders are excellent model systems for studying quantum phase transitions, as they exhibit a quantum critical point between non-magnetic spin singlet dimers to Néel magnetic order as inter-ladder exchange is increased. Ba2CuTeO6 is a Cu2+ S = 1/2 two-leg spin ladder system, that is close to the quantum critical point on the Néel ordered side. We have prepared the solid solution Ba2CuTe1-xWxO6 in an attempt to tune magnetic interactions past the quantum critical point. We will use muon spin rotation and relaxation to investigate the ground state of these materials. This will allow us to determine whether we have tuned the system to quantum criticality, or whether the materials remain magnetically ordered.

title: Superconductivity in the spinels: Cu(Ir_{1-x}Pt_x)2Se4 and CuRh2S4

description: Spinels, which have formula AB2X4 and crystallise in the cubic space group, exhibit a rich landscape of structural, magnetic and electronic properties. However, superconducting compounds of this family have proven fairly elusive. Previous routes to reaching superconductivity is via substitution of the A ion, such as Cu-Zn substitution in CuIr2S4. The parent compound exhibits a metal-insulator transition, concomitant with a complex structural transition and a charge-ordered and spin-dimerised state. We propose to investigate an alternative pathway to superconductivity via substitution of the B ion. The systems we would like to study are prototypical examples of this and muons as sensitive local probes can give us important information about the electric, magnetic and superconducting properties, such as the pairing mechanism, which gives insights into the electro-structural coupling.

title: Identifying the muon site in fluorine containing compounds

description: Fluorides form model systems with which we can test ideas about muon sites. We therefore propose a series of short experiments on well-defined fluoride systems that will be supported by a programme of DFT+mu; calculations and simulations of the nuclear-dipole coupling Hamiltonian to model the decoherent relaxation. Strongly bound F-mu-F states are favoured in alkali fluorides by the very electronegative nature of fluorine and the small ionic radius of the fluoride ion. But what if F is not in that state? What happens if fluorine happens to be part of a polyatomic anion so that the negative charge is shared between other components of the anion? In that case will the fluorine be a less attractive site for the muon? This experiment is designed to answer these questions by examining a series of carefully chosen compounds in which fluorine is incorporated as part of a more complex anion.

title: Superconductivity and magnetism in Cu2+-based coordination polymer [Cu3C6S6]n

description: Cu-BHT exhibits perfect kagome lattice of Cu2+ and previous combined magnetization and specific heat results suggested the presence of strong spin fluctuations. If there are indeed spin fluctuations arising from the frustrated Cu2+ kagome lattice where superconductivity occurs below 0.25 K, one would expect that spin fluctuations may play an important role in driving the superconductivity. However, our previous neutron scattering measurements on 9 grams of Cu-BHT powder did not observe magnetic excitations in the energy range above 0.2meV at 300mK. Therefore, it is still unclear whether magnetic order (and fluctuations at lower energy) is absent below 2K and the superconducting pairing is associated with spin fluctuations. To resolve this issue, we proposed to explore the superconducting gap symmetry and magnetic order of Cu-BHT at low temperature 40mK-3K.

title: Dynamics in staggered molecular spin chains

description: The ability to manipulate quantum states of matter is a goal of condensed matter science. Recent progress in molecular magnetism has shown the potential for gaining control over the structural building blocks of materials in order to engineer quantum magnetic properties. Our most recent work has concerned the chiral spin chain [Cu(pym)(H2O)4]SiF6.H2O (pym = pyrimidine) (1). The magnetic properties of this system most resemble those of a staggered spin chain, although the chiral structure of (1) appears to endow it with a unique field-induced excitation spectrum. In this project we propose to investigate the dynamic magnetic response of (1), comparing its excitation spectrum to that of the staggered chain material [pym-Cu(NO3)2(H2O)2].

title: Investigation of spin dynamics across quantum critical point in Co substituted CeRu2Ge2 using muon spin relaxation studies

description: Investigation of correlated behaviour in Ce based intermetallics has continued to fascinate researchers. These compounds exhibit novel ground states depending on the strength of the correlations. We intend to study the strongly correlated nature of CeRu2-xCoxGe2 which exhibits quantum critical behaviour near the critical concentration xc~1.5 using muon spin relaxation technique. Bulk measurements already performed on these series provide us with some insight regarding the correlated nature of electrons. The present investigation will help to test the complete absence of static magnetism as x tends to xc and to gain deeper knowledge regarding the correlated behaviour in this system.

title: Metadata for various molecular traits included in the eQTL Catalogue

description: Metadata for various molecular traits included in the eQTL Catalogue. The tab-separated files contain the following columns: <strong>phenotype_id</strong> - ID of the molecular trait that has been quantified. This can be either the gene ID (RNA-eq eQTLs), probe ID (microarray eQTLs), transcript ID (full-length transcript usage QTLs), splice junction ID (Leafcutter), exon id (exon-level QTLs) or any other molecular trait that has been quantified. <strong>quant_id</strong> - Used to quantify relative transcript usage or relative transcriptional event usage (in txrevise). <strong>group_id</strong> - Used for transcript usage and splicing phenotypes. Overlapping phenotypes whose relative expression is quantified belong to the same group (e.g. alternative spliced exons form clusters in Leafcutter). QTLTools permutation p-values are calculated accross all phenotypes within a group and only the phenotype with the smallest permutation p-value is reported. <strong>gene_id</strong> - Ensembl gene id <strong>chromosome</strong> - Chromosome of the gene <strong>gene_start</strong> - End coordinate of the gene (GRCh38) <strong>gene_end</strong> - Start coordinate of the gene (GRCh38) <strong>strand</strong> - Strand of the gene <strong>gene_name</strong> - Gene name extracted from Ensembl biomart. <strong>gene_type</strong> - Gene type extracted from Ensembl biomart. <strong>gene_gc_content</strong> - Percentage GC content of the gene. Extracted from Ensembl biomart and used as a covariate in cqn normalisation. Calculated with bedtools nuc for exons. <strong>gene_version</strong> - Ensembl gene version <strong>phenotype_pos</strong> - Genomic position used to determine the centre point of the <em>cis-</em>window for QTL mapping. By default this is the beginning of the gene (either gene start or gene end, depending on the strand of the gene). <strong>phenotype_length</strong> - (optional) - Length of the gene or exon in basepairs. Required to properly normalise featureCounts quantification results with cqn.

title: mSR study of charge carrier motion in thermally reduced graphene oxide

description: Graphene is attracting a lot of attention due to its promising properties for electronic devices. There are several methods to prepare graphene. Among them, reduction of graphene oxide (GO) is a low-cost approach to prepare graphene-based materials in a large scale. The GO sheets are decorated with oxygen-containing functional groups such as carboxylic, hydroxylic and epoxidic groups. Therefore, GO is nearly electrically insulating. Light illumination has important role on healing of conjugated bonds of GO by removing oxygen functional group from the molecule, so the conjugation length increased and GO become more conductive. We propose to study the microscopic intrinsic charge carrier motion of GO with different oxygen content to elucidate the intra-chain and inter-chain. We plan to perform zero field and longitudinal field mSR measurements of GO and RGO sample under light illumination
