description: We initiate a study of the holographic duals of a class of four-dimensional $\mathcal{N}=2$ superconformal field theories that are engineered by wrapping M5-branes on a sphere with an irregular puncture. These notably include the strongly-coupled field theories of Argyres-Douglas type. Our solutions are obtained in 7d gauged supergravity, where they take the form of a warped product of $AdS_5$ and a "half-spindle." The irregular puncture is modeled by a localized M5-brane source in the internal space of the gravity duals. Our solutions feature a realization of supersymmetry that is distinct from the usual topological twist, as well as an interesting Stückelberg mechanism involving the gauge field associated to a generator of the isometry algebra of the internal space. We check the proposed duality by computing the holographic central charge, the flavor symmetry central charge, and the dimensions of various supersymmetric probe M2-branes, and matching these with the dual Argyres-Douglas field theories. Furthermore, we compute the large-$N$ 't Hooft anomalies of the field theories using anomaly inflow methods in M-theory, and find perfect agreement with the proposed duality.

Developing electrochemical oligonucleotide templated reaction for microRNA detection
Creators: name: Gillespie, Philip Andrew
Publisher: name: Imperial College London
Year: 2020

description: MicroRNAs are non-coding RNA oligonucleotide sequences, approximately 22 nucleotides long that function in post transcriptional gene regulation. They are emerging biomarkers for many diseases, most notably cancer, and can be found in detectable quantities freely circulating in biological fluids. Up-regulation of one such microRNA (miR-141) is associated with locally advanced and metastatic prostate cancer and has potential as a minimally invasive biomarker for prostate cancer. Sequence specific detection of miRNAs is challenging because of their short length and high sequence homology between miRNAs. These problems can be tackled using Peptide Nucleic Acid (PNA) hybridisation probes and Oligonucleotide Templated Reactions (OTRs). PNA is a synthetic DNA analogue, in which the sugar phosphate backbone is replaced by an aminoethylglycine peptide chain. PNAs bind to natural nucleic acids (DNA or RNA) with high affinity and sequence specificity. Oligonucleotide templated reactions are reactions between chemically reactive moieties attached to oligonucleotides, catalysed by complementary binding a target sequence. Most OTRs reported generate an optical readout. The combination of PNA and OTR has previously been exploited in our lab as a valid approach for detecting microRNA from biological samples. Herein, we report on a new design of OTR with an electrochemical readout dubbed Electrochemical Oligonucleotide Templated Reaction (EOTR). Chapter 2 demonstrates the first example of EOTR between PNA probes complementary to miR-141. Ratiometric, quantitative and sequence-specific detection of miR-141 in vitro is 1 achieved. Chapter 3 uses computational molecular dynamics to simulate EOTRs as a potential new tool for in silico optimisation of PNA probes for miRNA sensing. Chapter 4 shows progress towards translating EOTR onto suitable platform via immobilising one of the PNA probes onto the surface of gold electrodes. Overall, this work shows the development of a new biosensing strategy that will hopefully be further translated into a miRNA sensing device for cancer diagnosis.

description: Efficient machine learning implementations optimized for inference in hardware have wide-ranging benefits, depending on the application, from lower inference latency to higher data throughput and reduced energy consumption. Two popular techniques for reducing computation in neural networks are pruning, removing insignificant synapses, and quantization, reducing the precision of the calculations. In this work, we explore the interplay between pruning and quantization during the training of neural networks for ultra low latency applications targeting high energy physics use cases. Techniques developed for this study have potential applications across many other domains. We study various configurations of pruning during quantization-aware training, which we term quantization-aware pruning, and the effect of techniques like regularization, batch normalization, and different pruning schemes on performance, computational complexity, and information content metrics. We find that quantization-aware pruning yields more computationally efficient models than either pruning or quantization alone for our task. Further, quantization-aware pruning typically performs similar to or better in terms of computational efficiency compared to other neural architecture search techniques like Bayesian optimization. Surprisingly, while networks with different training configurations can have similar performance for the benchmark application, the information content in the network can vary significantly, affecting its generalizability.

description: In this Letter we investigate the origin of the near-infrared emission of the Herbig Ae star MWC 758 on sub-astronomical unit (AU) scales using spectrally dispersed low resolution (R=35) AMBER/VLTI interferometric observations both in the H ($1.7 μ$m) and K ($2.2 μ$m) bands. We find that the K band visibilities and closure phases are consistent with the presence of a dusty disk inner rim located at the dust evaporation distance (0.4 AU) while the bulk of the H band emission arises within 0.1 AU from the central star. Comparing the observational results with theoretical model predictions, we suggest that the H band emission is dominated by an hot gaseous accretion disk.

Visualising socket pressure in lower-limb prostheses
Creators: name: Turner, Shruti
Publisher: name: Imperial College London
Year: 2021

description: Prosthetic sockets are a vital component of lower-limb prostheses, which must be individually made due to unique anatomy and requirements. Creating a prosthetic socket is an iterative process using theory and experience. There is no standard measurement system to aid socket creation despite the severe physical and psychosocial impacts of an ill-fitting socket. Various published studies outline socket pressure measurement systems in research; however, the limited number of technologies available for clinical use demonstrates minimal translation. This thesis outlines the steps taken through discovery and definition of the problem and developing and delivering a clinical biofeedback tool and data dashboard. The quantitative information is intended to complement subjective prosthesis user feedback to aid lower-limb prosthetic fitting and inform gait and movement re-education. First-hand perspectives of prosthetic rehabilitation experiences were sought to understand key issues. Socket fit was particularly important, with user testing establishing the desire for a greater understanding of socket pressure. Methods to gain objective measures of socket pressure were explored via a systematic review of published literature. Custom made piezoresistive sensors were chosen to demonstrate the value of translating socket pressure sensors into the clinical environment. Initial participant testing was conducted in the laboratory to collect pressure data during activities of daily living.

SU(5) unification of two triplet seesaw and leptogenesis with dark matter and vacuum stability

description: We investigate unification prospects of two heavy scalar triplet extension of the standard model where, in the absence of any right-handed neutrino (RHN), type-II seesaw accounts for current oscillation data with hierarchical neutrino masses consistent with cosmological bounds and the lighter triplet decay explains baryon asymmetry of the Universe via leptogenesis. We note that the absence of RHNs in the fundamental fermion representations of SU(5) delineates its outstanding position compared to SO(10) (or $E_6$). In addition, SU(5) needs smaller scalar representations ${15}_{H1}\oplus {15}_{H2}$ compared to much larger representations ${126}_{H1}\oplus {126}_{H2} \subset $ SO(10) (or ${351}^{\prime}_{H1}\oplus {351}^{\prime}_{H2} \subset E_6$). We show how precision gauge coupling unification is achieved through SU(5) with the predictions of different sets of two heavy triplet masses which, besides being compatible with type-II seesaw, are also consistent with unflavoured or $τ-$ flavoured leptogenesis. In addition to an intermediate mass colour octet fermion, completion of precision gauge coupling unification is found to require essentially the presence of the well known weak triplet fermion $Σ(3,0,1)$ in its mass range $M_Σ\simeq {\cal O}(500-3000)$ GeV out of which the dominant dark matter (DM) resonance mass $M_Σ\ge 2.4$ TeV is known to account for the observed cosmological relic density. The deficiency in relic density for lighter $Σ$ solutions is compensated by an additional scalar singlet DM. A GUT ansatz is noted to ensure vacuum stability of the SM scalar potential for all types of unification solutions realised in this work. We discuss proton lifetime estimations for $p\to e^+π^0$ compatible with the present Hyper-Kamiokande bound as a function of an unknown mixing parameter in the model.

description: We present a structural analysis of the multi-layer graphene-4HSiC(000-1}) system using Surface X-Ray Reflectivity. We show for the first time that graphene films grown on the C-terminated (000-1}) surface have a graphene-substrate bond length that is very short (0.162nm). The measured distance rules out a weak Van der Waals interaction to the substrate and instead indicates a strong bond between the first graphene layer and the bulk as predicted by ab-initio calculations. The measurements also indicate that multi-layer graphene grows in a near turbostratic mode on this surface. This result may explain the lack of a broken graphene symmetry inferred from conduction measurements on this system [C. Berger et al., Science 312, 1191 (2006)].

Design of compliant structures for aerial-aquatic robots
Creators: name: Winston, Crystal
Publisher: name: Imperial College London
Year: 2021

description: Currently, tasks like water quality sampling and underwater surveying utilize copious amounts of manual labor because they either require people to deploy aquatic sensors or coordinate actions between aerial and aquatic devices. However, the development of an aerial-aquatic robot that can fly to an aquatic location, collect data, and then fly back to land could dramatically reduce the need for such costly and potentially dangerous manual labor. Unfortunately, most aerial-aquatic robots that have been developed thus far us inefficient aquatic propulsion systems that limit mission times or are unable to successfully demonstrate a full mission cycle. For this reason, improving aerial-aquatic locomotion is still an area of active research. Most aerial-aquatic robots have been inspired by nature, as there are several animals that perform aerial-aquatic maneuvers. However, current robots are limited in how well they can emulate these animals because animals have naturally soft bodies, but their robotic counterparts are made from stiff materials and structures. The focus of my research is the design and modeling of lightweight flexible structures that will ultimately enable aerial-aquatic robots to better mimic the locomotion strategies we observe in nature. Both honeycomb and kirigami structures present a promising solution to this problem as they can be used to dramatically reduce the stiffness of a stiff and lightweight material. Here, I present two projects which demonstrate how both honeycomb and kirigami structures can be used for lightweight, flexible components of aerial-aquatic robots. Both projects present work towards the development of a camber morphing airfoil which can be used for aerial locomotion by allowing for more efficient flight and aquatic motion, by acting as a morphing sail that allows the vehicle to travel at the water's surface. Both of these serve as bio-inspired locomotion strategies, as wing morphing has been observed in many birds, and camber morphing sails have been observed in Portuguese Man-o-War jellyfish. I start by deriving 1D analytical models for honeycomb and kirigami structures and then demonstrate how those structures can be used as flexible aerial-aquatic robot building blocks in a self-sensing structure intended for a camber morphing wing. I then develop 3D models for diamond celled honeycombs and then use those models to design a shape-locking camber morphing wing. Ultimately, this research demonstrates how both honeycomb and kirigami structures can be used to build flexible components of aerial-aquatic robots that enable bio-inspired designs which more accurately imitate nature.

description: We give a brief review of the known effects of a dynamical vacuum cosmological component, the dark energy, on the anisotropies of the cosmic microwave background (CMB). We distinguish between a "classic" class of observables, used so far to constrain the average of the dark energy abundance in the redshift interval in which it is relevant for acceleration, and a "modern" class, aiming at the measurement of its differential redshift behavior. We show that the gravitationally lensed CMB belongs to the second class, as it can give a measure of the dark energy abundance at the time of equality with matter, occurring at about redshift 0.5. Indeed, the dark energy abundance at that epoch influences directly the lensing strength, which is injected at about the same time, if the source is the CMB. We illustrate this effect focusing on the curl (BB) component of CMB polarization, which is dominated by lensing on arcminute angular scales. An increasing dark energy abundance at the time of equality with matter, parameterized by a rising first order redshift derivative of its equation of state today, makes the BB power dropping with respect to a pure LambdaCDM cosmology, keeping the other cosmological parameters and primordial amplitude fixed. We briefly comment on the forthcoming probes which might measure the lensing power on CMB.

Using biomechanics to define the role of the upper extremity in rowing performance
Creators: name: Urbanczyk, Caryn Alexa
Publisher: name: Imperial College London
Year: 2021

description: Performance and injury risk are strongly affected by an athlete’s ability to consistently execute effective rowing technique. Previous rowing biomechanics studies focused on kinematic descriptions of the lower extremity and lumbar spine. Detailed biomechanical analyses of the upper extremity during rowing are limited, despite repetitive, high intensity loading across the shoulder complex and the prevalence of long-lasting upper extremity overuse injuries. This thesis aims to examine upper body biomechanics in ergometer rowing (for performance enhancement and injury mitigation), by developing kinematic and kinetic descriptions of technique. Computational modelling examined internal biomechanics, external kinematics, and performance metrics, across athletes of various ages and skill levels. Optical motion capture and bespoke instrumentation were used in whole-body tracking during ergometer rowing. Kinetic and kinematic data drove a multibody inverse dynamics model. Joint and muscle force patterns were analyzed to quantify upper extremity influence and create a biofeedback structure for rowers and coaches. As stroke rate increases, significant changes to the shape and timing of seat force profiles, shoulder joint angle profiles, and lumbar and thoracic spinal flexion, arose. Muscle force patterns highlight the importance of rotator cuff support for load transfer across the glenohumeral joint, with subscapularis and infraspinatus stabilizing the upper extremity before the finish and catch, respectively. Sex and age-related comparisons indicated differential prioritization of scapula stabilizers and prime movers in muscle force distribution. Masters rowers recruit arm accessory muscles but decrease rotator cuff force. Muscle forces impact external movement, joint forces, contact patterns, and shoulder stability, which over many cycles, have implications on performance and injury risk. Musculoskeletal modelling enhances spatio-temporal analyses, offering population-wide insight into how muscle and joint forces relate to traditional power metrics. Parameters provided deeper context on technique optimization for individual’s performance by identifying important muscles and the timing of their loading.

description: Data sharing in neuroimaging has been advocated for almost 15 years. Sharing data can in principle lead to more transparency, fewer methodological mistakes, new findings, as well as savings in data acquisition costs. On the other side some skeptics claimed in the past that “fMRI data per se are very context sensitive” which ”somewhat subverts the raison d’être for sharing”. Van Horn and Gazzaniga in their summary of fMRIDC highlight five successful studies reusing data deposited in their database. However, there has been no systematic survey of reuses of publicly available neuroimaging data. In this study we focus on the OpenfMRI database and the reuses of datasets deposited in it.

description: We derive the equations for the odd and even parity perturbations of coupled electromagnetic and gravitational fields of a black hole with an electric charge within the context of general nonlinear electrodynamics. The Lagrangian density is a generic function of the Lorentz invariant scalar quantities of the electromagnetic fields. We include the Hodge dual of the electromagnetic field tensor and the cosmological constant in our calculations. For each type of parity, we reduce the system of Einstein field equations coupled to nonlinear electrodynamics to two coupled Schrödinger-type wave equations, one for the gravitational field and one for the electromagnetic field. The stability conditions in the presence of the Hodge dual of the electromagnetic field are derived.

description: The matrix models which are conjectured to compute the circle Wilson loop and its correlator with chiral primary operators are mapped onto normal matrix models. A fermion droplet picture analogous to the well-known one for chiral primary operators is shown to emerge in the large N limit. Several examples are computed. We find an interesting selection rule for the correlator of a single trace Wilson loop with a chiral primary operator. It can be non-zero only if the chiral primary is in a representation with a single hook. We show that the expectation value of the Wilson loop in a large representation labelled by a Young diagram with a single row has a first order phase transition between a regime where it is identical to a large column representation and a regime where it is a large wrapping number single trace Wilson loop.

Intracellular trafficking of opsonized and unopsonized Pseudomonas aeruginosa in human monocyte-derived macrophages
Creators: name: Leung, Wendy Wen Sie
Publisher: name: University of British Columbia
Year: 2009

description: The intracellular fate of microorganisms ingested by phagocytes may be determined by the specific receptors mediating their uptake. To test this hypothesis, the subcellular location of Pseudomonas aeruginosa in human monocyte-derived macrophages upon phagocytosis via opsonic versus non-opsonic receptors was investigated by indirect double immunofluorescence. Opsonic ingestion of P. aeruginosa is glucose-independent while non opsonic phagocytosis of this bacterium by macrophages requires the presence of glucose. Therefore, opsonic and non-opsonic phagocytosis of P. aeruginosa were differentiated by presenting immunoglobulin-coated bacteria to macrophages in glucose-free medium and unopsonized bacteria to the phagocytes in the presence of glucose. Compartments of the opsonic and non-opsonic phagocytic pathways of P. aeruginosa in human monocyte-derived macrophages were defined by double-labelling infected macrophages with antibodies specific for different endocytic compartments (lysosomes, endosomes, etc.) and with polyclonal antibodies to P. aeruginosa. Both opsonized and unopsonized P. aeruginosa colocalized with the lysosomal-associated membrane glycoprotein, LAMP-i, which is found predominantly in lysosomes. Ingested opsonized P. aeruginosa appeared to colocalize with this LAMP-i + compartment at a faster rate than unopsonized P. aeruginosa. When cells were preloaded with rhodamine-ovalbumin to label secondary lysosomes, a small fraction of ingested bacteria that were phagocytosed via the two routes entered these labelled compartments. Brefeldin A, a drug which inhibits transport of newly synthesized membrane proteins and secretory proteins, and monensin, an ionophore which inhibits endosome acidification , did not influence the ingestion and intracellular fate of either opsonized or unopsonized P. aeruginosa. Mannose 6-phosphate receptor (MPR), an antigenic marker enriched in the late endosome, showed little colocalization with either opsonized or unopsonized P. aeruginosa. These studies suggest that both opsonized and unopsonized P. aeruginosa enter functionally similar pathways after phagocytosis by macrophages and that the phagosomes ultimately fuse with LAMP-1 compartments regardless of the receptor mediating the ingestion. Although it is not possible to determine definitively the stage at which the phagocytosed P. aeruginosa converged with the endocytic pathway, they appeared to do so at a stage that is distal to the late endosome, probably with prelysosomes.

description: We investigate the structure of the meson Regge trajectories based on the quadratic form of the spinless Salpeter-type equation. It is found that the forms of the Regge trajectories depend on the energy region. As the employed Regge trajectory formula does not match the energy region, the fitted parameters neither have explicit physical meanings nor obey the constraints although the fitted Regge trajectory can give the satisfactory predictions if the employed formula is appropriate mathematically. Moreover, the consistency of the Regge trajectories obtained from different approaches is discussed. And the Regge trajectories for different mesons are presented. Finally, we show that the masses of the constituents will come into the slope and explain why the slopes of the fitted linear Regge trajectories vary with different kinds of mesons.

description: In order to gain a better understanding of the origin of decoherence in superconducting flux qubits, we have measured the magnetic field dependence of the characteristic energy relaxation time ($T_1$) and echo phase relaxation time ($T_2^{\rm echo}$) near the optimal operating point of a flux qubit. We have measured $T_2^{\rm echo}$ by means of the phase cycling method. At the optimal point, we found the relation $T_2^{\rm echo}\approx 2T_1$. This means that the echo decay time is {\it limited by the energy relaxation} ($T_1$ process). Moving away from the optimal point, we observe a {\it linear} increase of the phase relaxation rate ($1/T_{2}^{\rm echo}$) with the applied external magnetic flux. This behavior can be well explained by the influence of magnetic flux noise with a $1/f$ spectrum on the qubit.

The effect of an extensive reading program on the reading proficiency and vocabulary knowledge of adult ESL readers
Creators: name: Lennig, Evelyn M.
Publisher: name: University of British Columbia
Year: 2009

description: Provincial and federal government surveys and commissions have consistently reported that English literacy training for adults with no or limited English is urgently needed and that access to training is limited. The effectiveness of existing literacy training programs and instructional strategies at the adult level has not been well researched. However, at the classroom level literacy training can be easily compromised by instructional strategies that limit the concept of full-literacy by focusing ESL literacy instruction on survival, functional and skill-building reading experiences. English and second language reading research suggests that student self-selection of reading materials and a high exposure to text are effective means of increasing vocabulary knowledge and reading proficiency. This study examined the effect of an Extensive Reading program on reading proficiency and vocabulary knowledge for 2 classes (N=33) of adult low intermediate ESL learners enrolled in a 15 week English language training program at a large Canadian community college. This quasi-experimental treatment group participated in a reading program supplemental to their regular classroom reading instruction. Subjects met weekly with the researcher and self-selected reading material from a collection of graded readers. Data on the frequency of the students' reading, their preferences in reading topics and materials and self-evaluations of their first and second language reading abilities were tallied for subjects in both groups. No statistical significant differences were found for the treatment in the analysis of assessments of reading and vocabulary. However, the experimental group posted higher gains in the group mean score on reading proficiency than the control group. Analysis of the Reading Behavior Survey suggests subjects in both groups were low frequency readers (less than 5 hours of reading time in English per week) who generally evaluated themselves fair to good readers in L2 but good to excellent readers in LI. The inconclusive results for the effect of the treatment on reading proficiency and vocabulary acquisition implies the need for future studies on the effectiveness of extensive reading programs on literacy training in ESL programs where literacy in English is a concern for students and educators.
Detailed Atmosphere Model Fits to Disk-Dominated ULX Spectra

description: We have chosen 6 Ultra-Luminous X-ray sources from the {\it XMM-Newton} archive whose spectra have high signal-to-noise and can be fitted solely with a disk model without requiring any power-law component. To estimate systematic errors in the inferred parameters, we fit every spectrum to two different disk models, one based on local blackbody emission (KERRBB) and one based on detailed atmosphere modelling (BHSPEC). Both incorporate full general relativistic treatment of the disk surface brightness profile, photon Doppler shifts, and photon trajectories. We found in every case that they give almost identical fits and similar acceptable parameters. The best-fit value of the most interesting parameter, the mass of the central object, is between 23 and 73 M$_\sun$ in 5 of the 6 examples. In every case, the best-fit inclination angle and mass are correlated, in the sense that large mass corresponds to high inclination. Even after allowing for this degeneracy, we find that, with $\gtrsim 99.9%$ formal statistical confidence, 3 of the 6 objects have mass $\gtrsim 25 M_\sun$; for the other 3, these data are consistent with a wide range of masses. A mass greater than several hundred $M_\sun$ is unlikely for the 3 best-constrained objects. These fits also suggest comparatively rapid black hole spin in the 3 objects whose masses are relatively well-determined, but our estimate of the spin is subject to significant systematic error having to do with uncertainty in the underlying surface brightness profile.

description: Two-particle azimuthal correlations have allowed detailed study of the modification to di-jets in the hot, dense medium created in RHIC collisions. Light can be shed by such correlations on many novel effects discovered at RHIC such as the enhanced p/pi ratio and conical structure of events with energy loss. Using pi0 triggers to reduce the effect of recombination we utilize high-pT correlations to explore the away-side structure.

description: Since the discovery of high-temperature superconductivity in the cuprates a theoretical understanding of their phase diagram has remained one of the major outstanding problems in condensed matter physics. Here we propose an effective low-energy Hamiltonian which produces both d-wave density wave (dDW) and d-wave superconducting (dSC) solutions within the BCS mean-field theory. This model predicts that (a) the observed pseudogap phase is a dDW state, (b) the superconducting phase is a d-wave BCS state, and (c) in the underdoped regime there is a gossamer superconducting state, i.e. dSC in coexistence with dDW. Moreover, this theory naturally explains the Uemura relation, the reduction of the quasiparticle density of states at the Fermi level, and the salient features in the tunneling conductivity measured in underdoped Bi2212.

description: We propose a nanoscale rotor embedded between two ferromagnetic electrodes that is driven by spin injection. The spin-rotation coupling allows this nanorotor to continuously receive angular momentum from an injected spin under steady current flow between ferromagnetic electrodes in an antiparallel magnetization configuration. We develop a quantum theory of this angular momentum transfer and show that a relaxation process from a precession state into a sleeping top state is crucial for the efficient driving of the nanorotor by solving the master equation. Our work clarifies a general strategy for efficient driving of a nanorotor.

Quantum Interpretations

description: Difficulties and discomfort with the interpretation of quantum mechanics are due to differences in language between it and classical physics. Analogies to The Special Theory of Relativity, which also required changes in the basic worldview and language of non-relativistic classical mechanics, may help in absorbing the changes called for by quantum physics. There is no need to invoke extravagances such as the many worlds interpretation or specify a central role for consciousness or neural microstructures. The simple, but basic, acceptance that what is meant by the state of a physical system is different in quantum physics from what it is in classical physics goes a long way in explaining its seeming peculiarities.

description: Mathematical modelling of unemployment dynamics attempts to predict the probability of a job seeker finding a job as a function of time. This is typically achieved by using information in unemployment records. These records are right censored, making survival analysis a suitable approach for parameter estimation. The proposed model uses a deep artificial neural network (ANN) as a non-linear hazard function. Through embedding, high-cardinality categorical features are analysed efficiently. The posterior distribution of the ANN parameters are estimated using a variational Bayes method. The model is evaluated on a time-to-employment data set spanning from 2011 to 2020 provided by the Slovenian public employment service. It is used to determine the employment probability over time for each individual on the record. Similar models could be applied to other questions with multi-dimensional, high-cardinality categorical data including censored records. Such data is often encountered in personal records, for example in medical records.

description: We explore the sensitivity to new physics for the coupling of the Higgs boson ($h$) and top quark ($t$) at high energy scales with the process $pp\to t\bar{t}h$ at the high-luminosity LHC. This process probes the coupling in both the space-like and time-like domains at a high scale, complementary to the off-shell Higgs processes in the time-like domain. The effects from physics beyond the Standard Model are parametrized in terms of the effective field theory framework and a non-local Higgs-top form factor. Focusing on the boosted Higgs regime in association with jet substructure techniques, we show that the present search can directly probe the Higgs-top coupling to good precision, providing a strong sensitivity to the new physics scale.

description: The reaction mechanism of projectile fragmentation at intermediate energies has been investigated observing the target dependence of the production cross sections of very neutron-rich nuclei. Measurement of longitudinal momentum distributions of projectile-like fragments within a wide range of fragment mass and its charge was performed using a hundred-MeV/n $^{40}$Ar beam incident on Be and Ta targets. By measurement of fragment momentum distribution, a parabolic mass dependence of momentum peak shift was observed in the results of both targets, and a phenomenon of light-fragment acceleration was found only in the Be-target data. The analysis of production cross sections revealed an obvious enhancement of the target dependence except target size effect when the neutron excess is increased. This result implies the breakdown of factorization (BOF) of production cross sections for very neutron-rich nuclei near the drip line.

Josephson Effect due to Odd-frequency Pairs in Diffusive Half Metals

description: The Josephson effect in superconductor / diffusive ferromagnet / superconductor (SFS) junctions is studied using the recursive Green function method in the regime of large exchange energy in a ferromagnet. Motivated by recent experiment [R. S. Keizer, et. al., Nature 439, 825 (2006)] we also address the case of superconductor / diffusive half metal / superconductor junctions. The pairing function in spin-singlet and triplet channels, the Josephson current and their mesoscopic fluctuations are calculated. We show that the spin-flip scattering at the junction interfaces opens the Josephson channel of the odd-frequency spin-triplet Cooper pairs. As a consequence, the local density of states in half metals has a large peak at the Fermi energy. Therefore odd-frequency pairs can be detected experimentally by using the scanning tunneling spectroscopy.
