Investigating the physiological role of glucokinase in central glucose sensing
Creators: name: Holton, Christopher
Publisher: name: Imperial College London
Year: 2015

description: The brain is dependent on a constant supply of glucose as its primary fuel. Consequently, the brain has developed ways to tightly control intake of glucose, via glucose sensing neurones containing the enzyme glucokinase (GK). This thesis identifies a role for a subset of glucose sensing neurones in the arcuate nucleus (ARC) of the hypothalamus to promote glucose intake. These neurones form part of a pathway separate to the control of peripheral glucose homeostasis. Direct injection of a GK activator into the ARC increases glucose intake. Stereotactic injection of recombinant adeno-associated virus containing GK antisense (rAAV-GKAS) into the ARC of rats chronically decreases GK activity compared to controls. Knockdown of ARC GK reduces glucose intake in an acute and long-term setting. Direct injection of an ATP-sensitive potassium (KATP) channel inhibitor into the ARC increases glucose intake in a similar manner to that of a GK activator. In addition, pre-treatment with a KATP channel activator attenuates the orexigenic effect of a GK activator. ARC glucose sensing neurones are likely mediated by neuropeptide Y (NPY) as both activation of GK and inhibition of KATP channels stimulate NPY release in hypothalamic explants. Also, pharmacological inhibition of Y1 and Y5 receptors, and P/Q type voltage gated calcium channels, attenuate the orexigenic effect of GK activators. ARC glucose sensing neurones represent a novel pathway that may be part of a mechanism to ensure adequate glucose is constantly available to the brain. This work suggests that ARC GK has a physiological role in the homeostatic regulation of glucose intake. ARC GK responds to periods of fasting and may contribute to an increased preference for glucose. Thus, ARC glucose sensing may drive dietary sugar intake, which may be a contributing factor in obesity.
The biology and trafficking of the FMS receptor
Creators: name: Chauhan, Rakhee
Publisher: name: Imperial College London
Year: 2014

description: The mature FMS receptor has been demonstrated here as being subject to constitutive loss as shown by S35 methionine labelling, live antibody labelling surface loss, surface biotinylation and FACS analysis with a half-life estimated at between 1 and 2 hours. This receptor turnover has been shown to be independent of kinase activity by the use of kinase impaired mutants and also a highly specific FMS kinase inhibitor, GW2580 that is able to inhibit the ligandinduced downregulation of FMS. The intracellular domain of the FMS receptor is believed not to be involved in the proteins constitutive downregulation from experiments performed here using domain deletion mutations and broad spectrum inhibition of other intracellular kinases. All experiments demonstrated FMS constitutive loss at the same rate as the wild-type and untreated receptor. The constitutive turnover has been further demonstrated to be distinct from FMS downregulation occurring via shedding and RIP mediated by ADAM17 and the γ-secretase complex respectively. We have demonstrated that the mechanism of receptor downregulation is independent of clathrin, caveolin and dynamin. FMS has been demonstrated here to pass through EEA1 and Rab7 positive compartments before its delivery to the lysosome for degradation. Our preliminary data suggests that the mechanism of FMS downregulation by the constitutive pathway is equivalent to that induced by M-CSF, but dissimilar from that of shedding and RIP degradation. These results also suggest that the c-KIT and VEGFR2 receptors are also subject to a similar mechanism of constitutive downregulation and both are also committed to degraded via the lysosome. To gain further insight into a possible raison d’ˆetre for the seemingly wasteful process of constitutively degrading the FMS receptor and also possibly the c-KIT and VEGFR2 receptors the 3 synthesis rates of FMS was analysed. The rates of FMS synthesis were shown to be constant irrespective of the receptors mature levels. Inhibition of the receptors degradation by lysosomal inhibition resulted in an increase in the levels of the mature receptor within cells. This was also demonstrated for the c-KIT and VEGFR2 receptors. As the synthesis rate of FMS was shown to be indepedent of its mature levels, we suggest that the constitutive degradation pathway is part of a homoeostatic mechanism whose function is to buffer receptor levels, preventing their overexpression in a simplistic system where they are synthesised at a constant rate.

Pervasive motion tracking and physiological monitoring
Creators: name: Woodward, Richard
Publisher: name: Imperial College London
Year: 2015

description: This thesis presents a new system of monitoring human motion and muscle activity concurrently, in pervasive and uncontrolled environments, for prolonged periods of time. Current technologies such as optical based motion tracking and electromyography (EMG) are considered the gold standard, but have limited use outside of a controlled laboratory environment. Restraints on collection durations, due to temporary sensors, as well as a limited collection space in which monitoring is capable, results in a constrained system which is not suitable for prolonged observation. Using a custom made inertial measurement unit (IMU) and mechanomyography (MMG) sensor, information from both motion and muscle activity was combined, in order to better understand human activity by allowing prolonged collection in unrestricted environments. IMU and MMG measurements have been compared to standard optical tracking and EMG measurements, demonstrating the viability of this technology in a clinical setting and particularly in the natural environment. This novel sensor is lightweight, inexpensive, low power, wireless, easy to use, gives results comparable to standard laboratory techniques, and is able to monitor motion and muscle activity over long periods of time. This work shows a strong agreement with the current literature on MMG response to increments of force, and a greater sensitivity to muscular fatigue detection when compared against EMG, all through pervasive studies. Using machine learning and pattern recognition methods, gait analysis and detection of progressive change over time was achieved in typical and atypical conditions, over prolonged periods. Finally, this work has shown applicable use in prosthesis control and gesture switching. Outside of muscle monitoring, alternative uses have been established, with preliminary results showing a suitable use in foetal monitoring. This work establishes a novel method of human motion and muscle monitoring which produces a suitably high accuracy when compared against the gold standard, however, without the limitations which confine the wearer to a finite space or limited duration time. The studies presented here introduce a number of areas in which prolonged and pervasive collection can expand this field, while producing complementary results against laboratory based technology.

description: We have obtained long-slit spectra of NGC 253 in the J, H, K, and N bands, broadband images in the J, H, and Ks bands, narrowband images centered at the wavelengths of BrGamma and H2(1,0)S(1), and imaging spectroscopy centered on [NeII](12.8um). We use these data and data from the literature in a comprehensive re-assessment of the starburst in this galaxy. We derive the supernova rate from the strength of the infrared [FeII] lines. We find that most of the H2 infrared luminosity is excited by fluorescence in low density gas. We derive a strong upper limit of ~37,000K for the stars exciting the emission lines. We use velocity-resolved infrared spectra to determine the mass in the starburst region. Most of this mass appears to be locked up in the old, pre-existing stellar population. Using these constraints and others to build an evolutionary synthesis model, we find that the IMF originally derived to fit the starburst in M 82 (similar to a Salpeter IMF) also accounts for the properties of NGC 253. The models indicate that rapid massive star formation has been ongoing for 20-30 million years in NGC 253---that is, it is in a late phase of its starburst. We model the optical emission line spectrum expected from a late phase starburst and demonstrate that it reproduces the observed HII/weak-[OI] LINER characteristics.

Hyperon-rich Matter in Neutron Stars

description: We study the equation of state of hyperon-rich matter for neutron stars using an extended relativistic mean-field model. We take special care of the recently proposed non-linear behaviour of the vector field which gives a much better description of Dirac-Brueckner calculations. The hyperon-hyperon interaction is also implemented by introducing additional meson exchanges. These new terms avoid the instability found at high densitites in previous works while keeping the excellent description for finite nuclear systems. We also demonstrate within the mean-field approach that the presence of hyperons inside neutron stars on one hand and the hyperon-hyperon interactions on the other hand make the onset of kaon condensation less favourable.

Studies on the relativistic electrons and x-rays generated by laser wakefield accelerators
Creators: name: Bloom, Michael Samuel
Publisher: name: Imperial College London
Year: 2014

description: Laser wakefield accelerators (LWFAs) operate through a high intensity ultra short laser pulse exciting a relativis- tic density wave in a plasma. I carried out experiments constructing LWFAs using lasers of a wide range of powers. Thereby allowing me to examine the generation of electrons and x-rays under these different conditions. The compar- ison of these results with my own and existing analytical models and computational modelling is discussed. In fulfilment of this, I developed novel techniques to measure hard x-rays in the tens of KeV energy range. In measure- ment of the relativistic electrons I found it possible to de- velop techniques to not only accurately measure the energy but also discern the three momentum vectors of electrons measured on a multiscreen electron spectrometer. As LWFAs open up the ability to produce high energy elec- tron beams without the need of tens of meters of RF accel- eration cavities and the lasers used to drive them can also be made relatively compact perhaps one of the most excit- ing application of this is the production of hard x-rays for imaging. As the source size of a LWFA betatron source is typically of micron scale, I investigated using LWFA derived x-rays for phase contrast imaging.

description: We study X-ray and soft gamma-ray spectral properties of BLRGs using data from Ginga, ASCA, OSSE and EXOSAT. The X-ray spectra are well fitted by an intrinsic power-law continuum with an energy index of alpha ~ 0.7, moderately absorbed by a cold medium. In addition, the Ginga spectra show Fe K-alpha lines with an average equivalent width of ~ 100 eV, and, in some cases, Compton reflection humps. However, the latter components are significantly weaker than both those seen in radio-quiet Seyferts and those expected if the Fe K-alpha lines were due to reflection. Some ASCA and EXOSAT spectra show soft X-ray excesses below ~ 3 keV. When that component is taken into account, the Fe K-alpha lines in the ASCA data become unresolved with equivalent widths < 200 eV. Multiple observations of 3C 390.3 and 3C 382 show the Fe K-alpha line approximately constant in flux but accompanied by strong continuum variations. This indicates the bulk of the line is formed by matter at a distance much larger than an accretion-disk scale, consistent with the ASCA line width measurements. The column density of the matter required to account for the observed line fluxes is N_H > 10^23 cm^-2. Such a medium is in the line-of-sight in 3C 445 but it has to be out of it in other objects, in which the observed N_H are substantially lower. Thus, a cold medium with that N_H and covering a large solid angle is out of the line-of-sight in most objects. The spectra of BLRGs break and become softer above ~ 100 keV, as shown by a simultaneous ASCA/OSSE observation of 3C 120 and by the OSSE spectra being on average much softer than the X-ray spectra. Finally, we find the X-ray and gamma-ray spectral properties of Cen A intrinsically very similar to BLRGs studied here.

description: Gaia DR2 provides a unique all-sky catalogue of 550'737 variable stars, of which 151'761 are long-period variable (LPV) candidates with G variability amplitudes larger than 0.2 mag (5-95% quantile range). About one-fifth of the LPV candidates are Mira candidates, the majority of the rest are semi-regular variable candidates. For each source, G, BP , and RP photometric time-series are published, together with some LPV-specific attributes for the subset of 89'617 candidates with periods in G longer than 60 days. We describe this first Gaia catalogue of LPV candidates, and present various validation checks. Various samples of LPVs were used to validate the catalogue: a sample of well-studied very bright LPVs with light curves from the AAVSO that are partly contemporaneous with Gaia light curves, a sample of Gaia LPV candidates with good parallaxes, the ASAS_SN catalogue of LPVs, and the OGLE catalogues of LPVs towards the Magellanic Clouds and the Galactic bulge. The analyses of these samples show a good agreement between Gaia DR2 and literature periods. The same is globally true for bolometric corrections of M-type stars. The main contaminant of our DR2 catalogue comes from young stellar objects (YSOs) in the solar vicinity (within ~1 kpc), although their number in the whole catalogue is only at the percent level. A cautionary note is provided about parallax-dependent LPV attributes published in the catalogue. This first Gaia catalogue of LPVs approximately doubles the number of known LPVs with amplitudes larger than 0.2 mag, despite the conservative candidate selection criteria that prioritise low contamination over high completeness, and despite the limited DR2 time coverage compared to the long periods characteristic of LPVs. It also contains a small set of YSO candidates, which offers the serendipitous opportunity to study these objects at an early stage of the Gaia data releases.

description: We present an extensive photometric and spectroscopic study of two high-redshift clusters of galaxies based on data obtained from the Keck 10m telescopes and the Hubble Space Telescope. The clusters CL0023+0423 (z=0.84) and CL1604+4304 (z=0.90) are part of a multi-wavelength program to study nine candidate clusters at z > 0.6 (Oke, Postman & Lubin 1998). Based on these observations, we study in detail both the field and cluster populations. From the confirmed cluster members, we find that CL0023+0423 actually consists of two components separated by ~2900 km/s. A kinematic analysis indicates that the two components are a poor cluster with ~3 x 10^{14} solar masses and a less massive group with 10^{13} solar masses. CL1604+4304 is a centrally concentrated, rich cluster at z = 0.8967 with a velocity dispersion of 1226 km/s and a mass of ~3 x 10^{15} solar masses. Approximately 57% and 50% of the galaxies show high levels of star formation in CL0023+0423 and CL1604+4304, respectively. These numbers are significantly larger than those found in intermediate redshift clusters. We also observe many old, red galaxies. Found mainly in CL1604+4304, they have spectra consistent with passive stellar evolution, typical of the early-type galaxies in low and intermediate-redshift clusters. We have calculated their ages by comparing their spectral energy distributions to standard Bruzual & Charlot evolutionary models. We find that their colors are consistent with models having an exponentially decreasing star formation rate with a time constant of 0.6 Gyr. We observe a significant luminosity brightening in our brightest cluster galaxies. Compared to BCGs at z < 0.1, we find a luminosity increase of ~1 mag in the rest B-band and ~0.8 mag in the rest V-band.

Stress hyperglycaemia in the acute care setting
Creators: name: Zalin, Anjali
Publisher: name: Imperial College London
Year: 2015

description: Introduction: Stress hyperglycaemia (SH), defined as transient hyperglycaemia during illness, is seen in up to 50% of inpatients and may progress to glucose intolerance in a significant proportion. SH is also associated with increased mortality. Despite this, there is no consensus on definition and management. Existing work focuses on single disease groups, frequently reporting adverse outcomes and variable success with therapies. There is, however, a scarcity of work profiling individuals with SH in detail. It is hoped that this approach may contribute to individualised management and improved outcomes for people with the condition. Methods: The central hypotheses of this work focus on metabolic profiling and were examined through a prospective observational study. Participants were allocated into study groups based on glucose levels. A 30-day follow-up was organised for people with SH. Novel biomarkers, tools and a diabetes risk calculator were employed to provide the most detailed profile currently available of individuals with stress hyperglycaemia. Finally, results from the first multicentre trial to bear on the effect of metformin in SH are presented. Results: The prevalence of SH was 34% and 31% in prospective (n=62) and metformin (n=52) studies respectively. People with SH had lower fasting insulin levels and insulin resistance. Otherwise, few differences were found. Metabolic profile, glycaemic variability, and HbA1c values were similar in both groups. Metabolic abnormalities and marked glycaemic excursions were also seen in both groups. Metformin was well tolerated but did not result in significantly reduced glucose variability or levels during the study period. Conclusions: People with SH do not appear to be phenotypically different from people without the condition. Marked hyper- and hypoglycaemia are common in hospital patients despite apparent normal glucose levels. Increased vigilance as well as timely and appropriate interventions could significantly improve outcomes for these individuals.

description: This is an on-line survey to evaluate the impact of a 3-month immersive learning fellowship program for scientists from low- and middle income countries, called the Next Generation Scientist (NGS) program.
Participants in the program underwent a structured learning curriculum and bespoke research activities tailored to the needs of each fellow. The research projects exposed the scientists to state-of-the-art methodologies and leading experts in their fields while also ensuring that learnings were implementable within their home infrastructure. Fellows ran seminars on drug discovery and development that reinforce themes of scientific leadership and teamwork together with practical modules on addressing healthcare challenges within their local systems.

The impact of the program was evaluated through this online survey of participants.
The survey consists of 18 multiple-choice and open-ended questions that assessed fellows’ academic, career and professional status, and evaluated their perceptions of impact of the NGS program on their professional trajectory and achievements.

description: The framed standard model (FSM), constructed initially for explaining the existence of three fermion generations and the hierarchical mass and mixing patterns of quarks and leptons, suggests also a "hidden sector" of particles including some dark matter candidates. It predicts in addition a new vector boson $G$, with mass of order TeV, which mixes with the $γ$ and $Z$ of the standard model yielding deviations from the standard mixing scheme, all calculable in terms of a single unknown parameter $m_G$. Given that standard mixing has been tested already to great accuracy by experiment, this could lead to contradictions, but it is shown here that for the three crucial and testable cases so far studied (i) $m_Z - m_W$, (ii) $Γ(Z \rightarrow \ell^ + \ell^-)$, (iii) $Γ(Z \rightarrow$ hadrons), the deviations are all within the present stringent experimental bounds provided $m_G > 1$ TeV, but should soon be detectable if experimental accuracy improves. This comes about because of some subtle cancellations, which might have a deeper reason that is not yet understood. By virtue of mixing, $G$ can be produced at the LHC and appear as a $\ell^+ \ell^-$ anomaly. If found, it will be of interest not only for its own sake but serve also as a window on to the "hidden sector" into which it will mostly decay, with dark matter candidates as most likely products.

Exploring the selection of creativity tools that suit personality attributes and design application
Creators: name: Yan, Yanliuxing
Publisher: name: Imperial College London
Year: 2017

description: This thesis reports an investigation on the enhancement of design engineers’ creativity. The key argument is that design engineers’ creative thinking can be stimulated by using creativity tools that suit their personality attributes and design application. It starts with looking at creativity in engineering design and the need for enhancing design engineers’ creative thinking. An integrated approach that combines the personality approach and use of creativity tools is adopted in this research. An investigation of design engineering students’ personality and their correlations with creative performance highlights that their personality preferences are distinctive from related populations, and their creative performance differ in an observable way, which emphases the importance of selecting creativity tools that are appropriate to design engineers so as to stimulate their creative thinking and transform into creative outcomes. An express personality test was produced to quickly determine individuals’ personality preferences. A creativity tool database was established based on the characterization of creativity tools to aid design engineers to use creativity tools flexibly. A case study was conducted to understand the use of creativity tools in engineering problem solving. The findings highlighted that besides design engineers’ personality attributes, design problem and environment also influence the use of creativity tools. A framework for selecting creativity tools was proposed by considering attributes of design engineers, the design problem, and the design environment. A creativity tool selection procedure was also proposed. The framework was applied in a design experiment where the proposed connection between personality attributes and creativity tools was investigated. The results imply that design engineers’ personality attributes have an influence on the preferences and application of creativity tools in idea generation. In conclusion, creativity tools can help stimulate design engineers’ creative thinking but factors such as personality attributes and design application should be considered.

description: The initial production and dynamical expansion of hot spherical nuclei are examined as the first stage in the projectile-multifragmentation process. The initial temperatures, which are necessary for entering the adiabatic spinodal region, as well as the minimum temperatures and densities, which are reached in the expansion, significantly differ for hard and soft equations of state. Additional initial compression, occurring in central collisions leads most likely to a qualitatively different multifragmentation mechanism. Recent experimental data are discussed in relation to the results of the proposed model.

description: We present a novel Affleck-Dine scenario for the generation of the observed baryon asymmetry of the Universe based on the non-trivial interplay between quintessential inflationary models containing a kinetic dominated post-inflationary era and a non-minimally coupled $U(1)$ field with a weakly broken $B-L$ symmetry. The non-minimal coupling to gravity renders heavy the Affleck-Dine field during inflation and avoids the generation of isocurvature fluctuations. During the subsequent kinetic era the Ricci scalar changes sign and the effective mass term of the Affleck-Dine field becomes tachyonic. This allows the field to dynamically acquire a large expectation value. The symmetry of the Affleck-Dine potential is automatically restored at the onset of radiation domination, when the Ricci scalar approximately equals zero. This inverse phase transition results in the coherent oscillation of the scalar field around the origin of its effective potential. The rotation of the displaced Affleck-Dine field in the complex plane generates a non-zero $B-L$ asymmetry which can be eventually converted into a baryon asymmetry via the usual transfer mechanisms.

A Closer Study of the Framed Standard Model Yielding Testable New Physics plus a Hidden Sector with Dark Matter Candidates

description: This closer study of the FSM: [I] retains the earlier results in offering explanation for the existence of three fermion generations, as well as the hierarchical mass and mixing patterns of leptons and quarks; [II] predicts a vector boson $G$ with mass of order TeV which mixes with $γ$ and $Z$ of the standard model. The subsequent deviations from the standard mixing scheme are calculable in terms of the $G$ mass. While these deviations for (i) $m_Z - m_W$, (ii) $Γ(Z \rightarrow \ell^+ \ell^-)$, and (iii) $Γ(Z \rightarrow {\rm hadrons})$ are all within present experimental errors so long as $m_G > 1$ TeV, they should soon be detectable if the $G$ mass is not too much bigger; [III] suggests that in parallel to the standard sector familiar to us, there is another where the roles of flavour and colour are interchanged. Though quite as copiously populated and as vibrant in self-interactions as our own, it communicates but little with the standard sector except via mixing through a couple of known portals, one of which is the $γ-Z-G$ complex noted in [II] above, and the other is a scalar complex which includes the standard model Higgs. As a result, the new sector appears hidden to us as we appear hidden to them, and so its lowest members with masses of order 10 MeV, being electrically neutral and seemingly stable, but abundant, may make eligible candidates as constituents of dark matter. A more detailed summary of these results together with some remarks on the model's special theoretical features can be found in the last section of the text.

description: The collective yrast band of the nucleus $^{48}$Cr is studied using the spherical shell model and the HFB method. Both approaches produce basically the same axially symmetric intrinsic state up to the - accurately reproduced - observed backbending. Agreement between both calculations extends to most observables. The only significant discrepancy comes from the static moments of inertia and can be attributed to the need of a more refined treatment of pairing correlations in the HFB calculation.

Studies of the roles of Lasso/Teneurin-2 and Latrophilin-1 in axon guidance and synaptic function
Creators: name: Vysokov, Nickolai
Publisher: name: Imperial College London
Year: 2014

description: It has been recently discovered that an adhesion G-protein-coupled receptor, latrophilin-1, interacts strongly and specifically with a single-pass transmembrane protein, called Lasso (latrophilin-1–associated synaptic surface organiser) or teneurin-2. Both proteins are expressed early in development, both are predominantly neuronal, and their knockouts result in embryonic lethality or nervous system-related defects. However, the biological role of their interaction is unknown. The thesis focuses on the functions of Lasso and latrophilin-1 in neuronal development, using dissociated hippocampal cell culture as a model of developing neurones. Immunocytochemistry and Western blotting demonstrate that latrophilin-1 resides primarily in axons, growth cones and presynaptic terminals, while Lasso largely localises in the postsynaptic membrane, indicating that in synapses the two proteins form a trans-synaptic pair. Surprisingly, Western Blotting has demonstrated that Lasso is also partially cleaved and released into the extracellular space. This released Lasso fragment binds to latrophilin-1-expressing cells, suggesting that it could affect axonal guidance by interaction with latrophilin-1 in growth cones. Using microfluidic chambers, a novel paradigm of quantitative assessment of axonal guidance in response to chemoattractant gradient has been developed and characterised. This was employed to demonstrate that soluble Lasso causes axon attraction and fasciculation. Once the growth cone reaches its Lasso-secreting target, latrophilin-1 binds the membrane-anchored Lasso, forming an inter-cellular link at the site of a future synapse. To elucidate the role of this interaction in synapse formation and/or activity, the latrophilin-1–Lasso complex in developing neuronal cultures was perturbed by the addition of an excess of the soluble latrophilin fragment. The resulting loss by latrophilin-1 of its endogenous ligand inhibits synaptic response to depolarising stimuli. These observations show that the released Lasso fragment may participate in axonal at- traction and membrane-anchored Lasso may play a role in transmitter exocytosis through its trans-synaptic complex with latrophilin-1. Hypothetical mechanisms and biological relevance of these processes in vivo are proposed.

description: Galaxy mass and environment play a major role in the evolution of galaxies. In the transition from star-forming to quenched galaxies, Active galactic nuclei (AGN) have also a principal action. However, the connections between these three actors are still uncertain. In this work we investigate the effects of stellar mass and the large-scale environment (LSS), on the fraction of optical nuclear activity in a population of isolated galaxies, where AGN would not be triggered by recent galaxy interactions or mergers. As a continuation of a previous work, we focus on isolated galaxies to study the effect of stellar mass and the LSS in terms of morphology (early- and late-type), colour (red and blue), and specific star formation rate (quenched and star-forming). To explore where AGN activity is affected by the LSS we fix the stellar mass into low- and high-mass galaxies. We use the tidal strength parameter to quantify their effects. We found that AGN is strongly affected by stellar mass in 'active' galaxies (namely late-type, blue, and star-forming), however it has no influence for 'quiescent' galaxies (namely early-type, red, and quenched), at least for masses down to $\rm 10^{10}\,[M_\odot]$. In relation to the LSS, we found an increment on the fraction of SFN with denser LSS in low-mass star forming and red isolated galaxies. Regarding AGN, we find a clear increment of the fraction of AGN with denser environment in quenched and red isolated galaxies, independently of the stellar mass. AGN activity would be 'mass triggered' in 'active' isolated galaxies. This means that AGN is independent of the intrinsic property of the galaxies, but on its stellar mass. On the other hand, AGN would be 'environment triggered' in 'quiescent' isolated galaxies, where the fraction of AGN in terms of sSFR and colour increases from void regions to denser LSS, independently of its stellar mass.

Dark matter in the KL moduli stabilization scenario with SUSY breaking sector from $\mathcal{N}=1$ SQCD

description: We investigate neutralino dark matter from a string/M-theory perspective. Using the Kallosh-Linde (KL) scenario to stabilize the string moduli requires supersymmetry breaking for uplifting to a de Sitter vacuum. We consider the free magnetic dual description of $\mathcal{N}=1$ SUSY QCD with massive flavours, the Intriligator-Seiberg-Shih model (ISS), as an F-term dynamical SUSY breaking sector. This framework allows for a gravitino mass in the TeV range. Moreover, due to the plethora of particles from the ISS sector, we investigate the consequences of coupling the MSSM with the KL-ISS setup to obtain constraints from both late entropy production and the dark matter relic density. In addition to thermal neutralino production, we consider neutralino production via the decays of gravitinos and ISS fields.

Controlling electron flow in anisotropic Dirac materials heterojunctions: a super-diverging lens

description: Ballistic heterojunctions of Dirac materials offer the opportunity of exploring optics-like phenomena in electronic systems. In this paper, a new perfect lens through special positive refraction is predicted with omnidirectional Klein tunneling of massless Dirac fermions. The novel optics component called a super-diverging lens (SDL) is the counterpart of a Veselago lens (VL). The use of SDL and VL creates a device that simulates the ocular vision. This atypical refraction is due to electrons obeying different Snell's laws of pseudo-spin and group velocity in heterojunctions with elliptical Dirac cones. These findings pave the way for an electron elliptical Dirac optics and open up new possibilities for the guiding of electrons.

description: We report the cumulative results of an on-going near-infrared search for redshifted H-alpha emission from normal galaxies at z>2. An infrared search reduces the bias due to reddening. Using narrow-band imaging with the Near Infrared Camera on the Keck I 10-m telescope, a survey area of almost 12 square arcminutes has been covered. Target regions were selected by matching the redshifts of QSO emission and metal-line absorptions to our available filters. The survey depth is 7E-17 ergs/cm^2/s (3sigma) in H-alpha and K-prime ~22. Eleven H-alpha-emitters, plus two Seyfert I objects, have been discovered. The high density of galaxy detections, corresponding to a co-moving volume density of 0.0135/Mpc^3, makes it unlikely that all of the H-alpha flux in these objects is the result of active nuclei. There is a strong suggestion of clustering in the environments of metal-line absorbers. Each candidate galaxy lies typically within a projected distance of 250kpc of the QSO line of sight and is resolved but compact. The average Star Formation Rate inferred for the galaxies from the H-alpha flux is 50 Msun/yr, significantly higher than current day star-forming galaxies, but consistent with other estimates for galaxies at high redshift.
