description: The simulation error (for calculation, see methods), individually normalised for each flight, is plotted against the navigational constant (N) used in the simulation, for each of the experimental conditions (Coenosia or Holcocephala, linear or erratic targets). Mean and standard error for each panel are represented by the coloured lines and shaded areas respectively. The sensitivity of fitting N to trajectories by the alignment of simulation velocity with true fly velocity is indexed by the steepness of the slope of the mean line.

Centaurus A - NGC 5128

description: This review summarizes the state of the knowledge of the nearby (D = 3.4 Mpc) radio source Centaurus A and its host galaxy NGC 5128. The massive elliptical host galaxy appears to be moderately triaxial. It contains a strongly warped thin disk, rich in gas, dust and young stars, and roughly aligned with the minor axis of the elliptical galaxy. This and other evidence suggests that NGC 5128 has experienced a major merger at least once in its past. The subparsec nucleus is variable at radio and X-ray wavelengths and is probably powered by accretion onto a black hole of moderate mass. HI and molecular line absorption against the nucleus suggest significal inflow of material. Linear radio/X-ray jets emanating from the nucleus become subrelativistic at a few parsec, expand into plumes at about 5 kpc, and then turn into huge radio lobes extending out to 250 kpc. A compact disk surrounds the nucleus. It is not aligned with any of the principal axes of the elliptical galaxy, but perpendicular to the inner jets. The jet-collimating mechanism, probably tied to this circumnuclear disk, appears to be precessing on timescales of a times 10**7 yerars.

description: In robotic deformable object manipulation (DOM) applications, constraints arise commonly from environments and task-specific requirements. Enabling DOM with constraints is therefore crucial for its deployment in practice. However, dealing with constraints turns out to be challenging due to many inherent factors such as inaccessible deformation models of deformable objects (DOs) and varying environmental setups. This article presents a systematic manipulation framework for DOM subject to constraints by proposing a novel path set planning and tracking scheme. First, constrained DOM tasks are formulated into a versatile optimization formalism which enables dynamic constraint imposition. Because of the lack of the local optimization objective and high state dimensionality, the formulated problem is not analytically solvable. To address this, planning of the path set, which collects paths of DO feedback points, is proposed subsequently to offer feasible path and motion references for DO in constrained setups. Both theoretical analyses and computationally efficient algorithmic implementation of path set planning are discussed. Lastly, a control architecture combining path set tracking and constraint handling is designed for task execution. The effectiveness of our methods is validated in a variety of DOM tasks with constrained experimental settings.

description: We show that there exists an exact solution for a lossless and reciprocal periodic surface impedance which ensures full conversion of a single-mode surface wave propagating along the impedance boundary to a single plane wave propagating along a desired direction in free space above the boundary. In contrast to known realizations of leaky-wave antennas, the optimal surface reactance modulation which is found here ensures the absence of evanescent higher-order modes of the Floquet wave expansion of fields near the radiating surface. Thus, all the energy carried by the surface wave is used for launching the single inhomogeneous plane wave into space, without accumulation of reactive energy in higher-order modes. The results of the study are expected to be useful for creation of leaky-wave antennas with the ultimate efficiency, and, moreover, can potentially lead to novel applications, from microwaves to nanophotonics.

Aetiological factors in the pathogenesis of male genital lichen sclerosus, penile precancer and penile cancer
Creators: name: Shim, Tang Ngee
Publisher: name: Imperial College London
Year: 2016

description: Male genital lichen sclerosus (MGLSc) results in sexual and urological dysfunction and predisposes to penile intraepithelial neoplasia (PeIN) and squamous cell carcinoma of the penis (PSCC). The pathogenesis of MGLSc is controversial. Evidence has accumulated that it is due to chronic, occluded exposure to urine caused by post-micturition microincontinence. Infection with hepatitis C (HCV) or human papillomavirus (HPV), autoimmunity and HLA immunogenotype have been incriminated. PeIN and PSCC are associated with HPV and MGLSc. Down-regulation of the gene Cables 1 (associated with squamous carcinogenesis) has been reported in MGLSc. The role of HLA in PeIN and PSCC is unknown. Urinary microincontinence, HPV, HLA, HCV and Cables 1 have been investigated in MGLSc (n=88), PeIN (n=72) and PSCC (n=37). Clinical charts were reviewed retrospectively for microincontinence. HCV antibody titres were assayed serologically. Cables 1 expression was assessed by immunohistochemistry of biopsies. DNA was extracted from blood and tissue for broad-spectrum HPV and comprehensive HLA typing by specific and sensitive PCR-based methodologies. Nearly 90% of men with GLSc (p=<0.01) had post-micturition microincontinence. HPV was identified in 37.5% of cases of MGLSc (n=88), 90.2% PeIN and 54.1% PSCC. MGLSc was associated with 34.7% cases of PeIN. No significant HLA associations were found in MGLSc. Significant (p<0.05) HLA associations were i) susceptibility to a) PeIN (C*15) - specifically HPV16 +ve PeIN (C*15, DQA1*02, DQA1*03) and b) HPV16 +ve PSCC (B*57), and ii) protection against PeIN (DQA1*01). No association between HCV and MGLSc was found. Cables 1 expression was normal. Microincontinence and urinary exposure are implicated in the pathogenesis of MGLSc. HPV is involved in the pathogenesis of PeIN and PSCC but associated with MGLSc only as a passenger phenomenon. Immunogenotype may play a role in the pathogenesis of PeIN and PSCC but not of MGLSc. HCV and Cables 1 are not important in MGLSc.

description: Data were rotated onto the engagement plane, defined by the starting position of the fly and the two points of greatest displacement of the target. The plane has axes X & Y while distance orthogonal to the plane is in axis Z. The summed displacements between fly and target in each dimension are given for Holcocephala and linear (i.) & erratic (ii.) targets and Coenosia linear (i.) & erratic (ii.) targets. The Z dimension is removed when correlating the rotation in pursuer heading with rotation in the LoS.

description: The breaking of ergodicity in isolated quantum systems with a single-particle mobility edge is an intriguing subject that has not yet been fully understood. In particular, whether a nonergodic but metallic phase exists or not in the presence of a one-dimensional quasiperiodic potential is currently under active debate. In this Letter, we develop a neural-network-based approach to investigate the existence of this nonergodic metallic phase in a prototype model using many-body entanglement spectra as the sole diagnostic. We find that such a method identifies with high confidence the existence of a nonergodic metallic phase in the midspectrum at an intermediate quasiperiodic potential strength. Our neural-network based approach shows how supervised machine learning can be applied not only in locating phase boundaries but also in providing a way to definitively examine the existence or not of a novel phase.

description: Precessing accretion discs have long been suggested as explanations for the long periods observed in a variety of X-ray binaries, most notably Her X-1/HZ Her. We show that an instability of the disc's response to the radiation reaction force from the illumination by the central source can cause the disc to tilt out of the orbital plane and precess in something like the required manner. The rate of precession and disc tilt obtained for realistic values of system parameters compare favourably with the known body of data on X-ray binaries with long periods. We explore other possible types of behaviour than steadily precessing discs that might be observable in systems with somewhat different parameters. At high luminosities, the inner disc tilts through more than 90 degrees, i.e. it rotates counter to the usual direction, which may explain the torque reversals in systems such as 4U 1626-67.

Radiation transport in multiphase and spatially random media
Creators: name: Park, Samuel
Publisher: name: Imperial College London
Year: 2016

description: An important class of problems within radiation (e.g. neutrons, photons) transport are those in which the radiation migrates through a medium which has a random or stochastic composition. The uncertain medium composition introduces an uncertainty in the radiation angular/scalar flux, current, reaction rates and other quantities of interest. Stochastic media play an important role within radiation transport and have numerous applications such as radiation shielding, nuclear criticality assessment, as well as radiative transfer in clouds, stellar atmospheres and plasma physics. Stochastic radiation transport problems reduce to treating the adsorption, scatter and other macroscopic cross-section data as spatially correlated random fields. Several methods for the treatment of these uncertain-ties have been proposed however they are limited in their scope and computational efficiency. Multiphase and spatially random media are often characterised by non-Gaussian random fields which are much more challenging to model than Gaussian random fields. This thesis aims to investigate, develop and implement mathematically rigorous computational algorithms that are more efficient than the current methods for solving radiation transport with multiphase and spatially random media. In particular this thesis applies iso-probabilistic (e.g. Nataf) transforms to transform Gaussian random fields into non-Gaussian random fields. This approach enables the use of optimal spectral stochastic representations, such as the Karhunen-Loève and generalized polynomial chaos methods, to be used to simulate non-Gaussian random fields. This thesis also describes the verification of these iso-probabilistic spectral stochastic projection methods against standard radiation transport in random media benchmarks, such as the widely used Adams-Levermore-Pomraning benchmark. This thesis is the first time the general Nataf method has been applied to model radiation transport through multiphase and spatially random media.
Local Hydrodynamic Stability of Accretion Disks

description: We employ a variety of numerical simulations in the local shearing box system to investigate in greater depth the local hydrodynamic stability of Keplerian differential rotation. In particular we explore the relationship of Keplerian shear to the nonlinear instabilities known to exist in simple Cartesian shear. The Coriolis force is the source of linear stabilization in differential rotation. We exploit the formal equivalence of constant angular momentum flows and simple Cartesian shear to examine the transition from stability to nonlinear instability. The manifestation of nonlinear instability in shear flows is known to be sensitive to initial perturbation and to the amount of viscosity; marginally (linearly) stable differentially rotating flows exhibit this same sensitivity. Keplerian systems, however, are completely stable; the strength of the stabilizing Coriolis force easily overwhelms any destabilizing nonlinear effects. In fact, nonlinear effects speed the decay of applied turbulence by producing a rapid cascade of energy to high wavenumbers where dissipation occurs. Our conclusions are tested with grid resolution experiments and by comparison with results from a code that employs an alternative numerical algorithm. The properties of hydrodynamic differential rotation are contrasted with magnetohydrodynamic differential rotation. The kinetic stress couples to the vorticity which limits turbulence, while the magnetic stress couples to the shear which promotes turbulence. Thus magnetohydrodynamic turbulence is uniquely capable of acting as a turbulent angular momentum transport mechanism in disks.

description: It has recently been suggested that the stars in a vertical extension of the red clump feature seen in LMC color-magnitude diagrams could belong to a tidal stream of material located in front of that galaxy. If this claim is correct, this foreground concentration of stars could contribute significantly to the rate of gravitational microlensing events observed in the LMC microlensing experiments. Here we present radial velocity measurements of stars in this so-called ``vertical red clump'' (VRC) population. The observed stellar sample, it transpires, has typical LMC kinematics. It is shown that it is improbable that an intervening tidal stream should have the same distribution of radial velocities as the LMC, which is consistent with an earlier study that showed that the VRC feature is more likely a young stellar population in the main body of that galaxy. However, the kinematic data do not discriminate against the possibility that the VRC is an LMC halo population.

description: The cell wall polymer callose catalyses the formation of silica in vitro and is heavily implicated in biological silicification in Equisetum (horsetail) and Arabidopsis (thale cress) in vivo. Callose, a β-1,3-glucan, is an ideal partner for silicification, because its amorphous structure and ephemeral nature provide suitable microenvironments to support the condensation of silicic acid into silica. Herein, using scanning electron microscopy, immunohistochemistry and fluorescence, we provide further evidence of the cooperative nature of callose and silica in biological silicification in rice, an important crop plant and known silica accumulator. These new data along with recently published research enable us to propose a model to describe the intracellular events that together determine callose-driven biological silicification.

description: Machine-learning based intrusion detection classifiers are able to detect unknown attacks, but at the same time, they may be susceptible to evasion by obfuscation techniques. An adversary intruder which possesses a crucial knowledge about a protection system can easily bypass the detection module. The main objective of our work is to improve the performance capabilities of intrusion detection classifiers against such adversaries. To this end, we firstly propose several obfuscation techniques of remote attacks that are based on the modification of various properties of network connections; then we conduct a set of comprehensive experiments to evaluate the effectiveness of intrusion detection classifiers against obfuscated attacks. We instantiate our approach by means of a tool, based on NetEm and Metasploit, which implements our obfuscation operators on any TCP communication. This allows us to generate modified network traffic for machine learning experiments employing features for assessing network statistics and behavior of TCP connections. We perform the evaluation of five classifiers: Gaussian Naive Bayes, Gaussian Naive Bayes with kernel density estimation, Logistic Regression, Decision Tree, and Support Vector Machines. Our experiments confirm the assumption that it is possible to evade the intrusion detection capability of all classifiers trained without prior knowledge about obfuscated attacks, causing an exacerbation of the TPR ranging from 7.8% to 66.8%. Further, when widening the training knowledge of the classifiers by a subset of obfuscated attacks, we achieve a significant improvement of the TPR by 4.21% - 73.3%, while the FPR is deteriorated only slightly (0.1% - 1.48%). Finally, we test the capability of an obfuscations-aware classifier to detect unknown obfuscated attacks, where we achieve over 90% detection rate on average for most of the obfuscations.
The effects of dietary interventions on metabolic flexibility
Creators: name: Lim, Chong
Publisher: name: Imperial College London
Year: 2017

description: Metabolic flexibility is defined as the ability of an organism to adapt from fuel oxidation to fuel availability. It is well established that obesity results in loss of metabolic flexibility, however, the exact mechanism remains unclear. Therefore, it is critical to understand the mechanism underlying metabolic flexibility to tackle the epidemic of obesity. An energy-restricted diet will lead to weight loss. However, little is known regarding the mechanisms behind the improvement in metabolic flexibility with weight loss following an energy-restricted diet. In investigation 1, I compared the effects of an energy-restricted diet and a control diet over 12 weeks on overweight and obese volunteers to elucidate the underlying mechanism of metabolic flexibility. The results demonstrated that weight loss is associated with significant reductions in body fat composition, waist circumference, hip circumference, visceral fats, blood pressure, and an improvement in postprandial insulin sensitivity. This translates into an improvement in metabolic health and metabolic flexibility. However, the underlying mechanism remained unclear. Furthermore, dietary modification using short chain fatty acids provides an attractive avenue to improve metabolic flexibility. However, the evidence for the role of short chain fatty acids in improving human metabolic flexibility is lacking. In order to investigate the effects of short chain fatty acids on metabolic flexibility, I used encapsulated sodium propionate, which is a novel method to explore its effects on glucose homeostasis. Investigation 2 consists of two parts. The first part of the study was to demonstrate the pharmacokinetic profile of encapsulated sodium propionate. The results demonstrated no significant changes in serum propionate concentrations following ingestion of encapsulated sodium propionate. The second part of the study was designed to establish the most effective dose of sodium propionate in improving glucose homeostasis. Results from this part of the study demonstrated no significant change in beta cell function.

description: We determine the X-ray spectral properties of a sample of low-mass X-ray binaries (LMXBs) which reside in globular clusters of M31, as well as five LMXBs in Galactic globular clusters and in the Large Magellanic Cloud using the ROSAT PSPC. We find a trend in the X-ray properties of the LMXBs as a function of globular cluster metallicity. The spectra of LMXBs become progressively softer as the metallicity of its environment increases. The one M31 globular cluster LMXB in our sample which has a metallicity greater than solar has spectral properties similar to those of LMXBs in the bulge of M31, but markedly different from those which reside in low metallicity globular clusters, both in M31 and the Galaxy. The spectral properties of this high metallicity LMXB is also similar to those of X-ray faint early-type galaxies. This lends support to the claim that a majority of the X-ray emission from these X-ray faint early-type galaxies results from LMXBs and not hot gas, as is the case in their X-ray bright counterparts.

Je n'ai pu avoir plutôt, mon cher Monsieur, les antiquités de Beaune que je vous avais promises. Il n'y a qu'un mois que le libraire les distribue et j'ai toujours attendu une occasion pour nous les faire parvenir. La voie des voituriers publiques sont (sic.) d'une lenteur insupportable surtout lorsqu'elle arrête en chemin. Lyon, où elles s'arrêtent ne remettent pas exactement à leur adresse. On laisse les paquets dans les bureaux ou souvent on les oublie et les commis des bureaux ne veulent pas se charger de [fol. 215 v] les faire rendre francs de port au lieu de leur destination même en les payant d'avance, parce qu'ils ne savent pas dit-on ce qu'il en coûtera passé Lyon. Joigniez à cela que la chambre syndicale arrête tout, contrôle tout, ne respecte jamais rien. J'ai trouvé par aventure la femme d'un négociant droguiste qui part pour Marseille, qui ira à ce qu'elle espère à Nîmes y voir un frère, ou remettra le livre et la lettre au Pont du Saint-Esprit pour vous être rendu à Nîmes, si elle n'a pas la commodité d'y aller. J'ai cru cette voie plus courte et plus commode. Je souhaite que le livre vous fasse plaisir. Vous y verrez quelque planche gravée, mais l'auteur n'a apparemment voulu travailler que [fol. 216 r] pour sa ville. Il est entré dans trop de détail qui intéresse peu les autres et qui leur causent souvent des bâillements. La matière d'ailleurs étant peu amusante, mais il a des vues patriotiques qui font honneur à son coeur.

J'ai de nouvelles grâces à vous rendre de vos bontés pour l'ornement de mon jardin de botanique. Vous verrez par le catalogue que vous trouverez dans le livre les plantes et les graines qui n'ont pas repris. Elles sont un nouveau sujet pour exercer vos libéralités. Si vous pouvez m'en tenir ou en partie rétablir ce qui nous manque, je vous aurai de grandes obligations. J'ai écrit à un ami en Angleterre et lui envoie un détail des plantes de la Virginie que je désire avoir. J'ai un ami qui m'a promis de m'acheter du jardinier de Trianon les plantes qu'on en pourra tirer. J'espère entre autres avoir le tulipier qui est très cher, enfin je ferai ce que je pourrai pour garnir le plus que je pourrai ce pays de ce qu'il y a de bon et tacherai de vous procurer toute ma vie ma reconnaissance et ma tendre amitié.

description: The effect of disorder on lattice vibrational modes has been a topic of interest for several decades. In this work, we employ a Green's function based approach, namely the dynamical cluster approximation (DCA), to investigate phonons in mass disordered systems. Detailed benchmarks with previous exact calculations are used to validate the method in a wide parameter space. An extension of the method, namely the typical medium DCA (TMDCA), is used to study Anderson localization of phonons in three dimensions. We show that, for binary isotopic disorder, lighter impurities induce localized modes beyond the bandwidth of the host system, while heavier impurities lead to a partial localization of the low-frequency acoustic modes. For a uniform (box) distribution of masses, the physical spectrum is shown to develop long tails comprising mostly localized modes. The mobility edge separating extended and localized modes, obtained through the TMDCA, agrees well with results from the transfer matrix method. A re-entrance behavior of the mobility edge with increasing disorder is found that is similar to, but somewhat more pronounced than, the behavior in disordered electronic systems. Our work establishes a new computational approach, which recovers the thermodynamic limit, is versatile and computationally inexpensive, to investigate lattice vibrations in disordered lattice systems.

description: Aims The aim of this thesis was to investigate, for supervised training in laparoscopic colorectal surgery (LCS); clinical safety, proficiency gain, training quality and programme structure. The specific objectives were (1) define national learning curves for LCS and analyse the clinical safety of supervised LCS training (2) assess the performance of supervised LCS trainees and define their proficiency gain (3) evaluate the impact of training quality and programme structure. Methods Objective 1: National data was used to create national proficiency gain curves and define the national clinical outcomes for LCS. Clinical data and proficiency gain curves from the National Training Programme (NTP) and laparoscopic fellowships were compared against this. Objective 2: The formative Global Assessment Scale (GAS) scores were used to assess the performance and define the competency proficiency gain for supervised LCS training. Summative Competency Assessment Tool (CAT) scores were used to assess trainee performance on completion of training. Objective 3: Mini-Structured Training Trainer Assessment Report (mini-STTAR) scores were used to measure training quality and the impact of the Lapco-TT course. A survey study was used to evaluate the structural and organisational quality of the NTP. Results There has been a national learning curve for mortality associated with the introduction of LCS. Supervised training in LCS flattened the clinical learning curve and prevented unnecessary patient harm. The supervised competency proficiency gain curve for LCS was around 30 cases. Increased training volume improved technical performance in objective summative competency assessment, which in turn improved clinical outcomes. The quality of the training, structure and organisation was high and Lapco-TT course augmented training. Conclusion The introduction of novel surgical techniques is associated with patient harm. LCS was learnt safely, efficiently and effectively within the NTP. The NTP model, including the structure, organisation, competency assessment and audit provides a template for future training programmes.

description: We present and discuss a "3-dimensional" diagnostic diagram for Seyfert2 galaxies obtained by means of X-ray and [OIII] data on a large sample of objects (reported in the Appendix). The diagram shows the Kalpha iron line equivalent width as a function of both the column density derived from the photoelectric cutoff and the 2-10 keV flux normalized to the [OIII] optical line flux (the latter corrected for extinction and assumed to be a true indicator of the source intrinsic luminosity). We find that the hard X-ray properties of type 2 objects depend on a single parameter, the absorbing column density along the line of sight,in accordance with the unified model. The diagram can be used to identify Compton thick sources and to isolate and study peculiar objects. From this analysis we have obtained a column density distribution of Seyfert 2 galaxies which is thought to be a good approximation of the real distribution. A large population of heavily absorbed objects is discovered, including many Compton thick candidates. Our results indicate that the mean Log Nh/cm^(-2)in type 2 Seyferts is 23.5 and that as much as 23-30% of sources have Nh > 10^24 cm^(-2).

Electron-vibration-vibration two-dimensional infrared spectroscopy as a structural probe of interactions in proteins and DNA

description: Modern structural biology has a number of powerful tools but despite this there are a number of problems in structural biology that these methods are unable to address. Some of these pertain to the need for large number for precise comparative structures for the drug discovery process. EVV 2DIR has the potential to fill some of these gaps, having the potential to determine molecular binding geometry. This thesis presents the first steps in exploring the potential of EVV 2DIR to be applied to the analysis of the structure of inhibitor- protein binding and presents the first EVV spectra of an inhibitor-protein complex. For the inhibitor-protein complex studied, six vibrational couplings between seven vibrational modes were identified exclusively upon complex formation due to interactions between the two molecules. Experimental spectra were compared with ab initio calculations to assign these vibrations to specific motions on both the inhibitor and protein molecules. EVV 2DIR cross peaks can be sensitive to the geometry of the interacting groups which produce them. By measuring the spectra of the inhibitor-protein complex using two different polarisation schemes, quantitative comparison between calculated and experimental spectra was made possible. This allowed for the prospect of using calculation aided EVV 2DIR to determine the structure of protein-ligand complexes to be explored. This thesis also presents the first EVV spectra of DNA. EVV 2DIR spectra were measured of duplex and G-quadruplex structures and compared with those of unstructured controls. In the absence of calculated spectra, assignments were made to some of the spectral features observed. EVV 2DIR was shown to be sensitive to the structural form of the DNA samples, containing cross peaks indicative of WatsonCrick base pairing, G-quadruplex formation and glycosidic bond conformation. The DNA spectra contained many unassigned peaks leaving open the possibility to assign many more structural indicators.
Effect of embryonic stem cell culture condition on the cellular identities of human amniotic fluid stem cells

description: Amniotic fluid stem cells (AFSCs) offer therapeutic potential for prenatal and neonatal diseases based on their unique features. From the development of embryos, AFSCs represent a category between embryonic stem cells (ESCs) and mesenchymal stem cells (MSCs), with AFSCs more primitive than MSCs. Our lab has previously established that AFSCs can be reprogrammed to regain functional pluripotency with valproic acid (VPA). However, detailed mechanisms are still unknown. Here, our results showed that Wnt signalling was downregulated in the initial stage and upregulated with VPA treatment; whereas mesenchymal-to-epithelial transition (MET) was not observed in the process. Additionally, our previous results demonstrated that AFSCs maintained in ESC conditions shared 82% transcriptome similarity with ESCs. In the second part of this study, we revealed that features of AFSCs including marker expression and differentiation ability were sustained better in ESC conditions. Regarding osteogenesis, enhanced osteogenic ability was found in AFSCs maintained in ESC conditions due to a TGF-beta/CD73-dependent signalling pathway. Moreover, in addition to possessing the same tri-lineage differentiation capability as MSCs, AFSCs can also be induced to express cardiac markers, but contractile cells have not been obtained yet. As features of AFSCs are better preserved in ESC conditions, a Wnt-dependent cardiomyocyte differentiation protocol for pluripotent stem cells is examined on AFSCs in the last part of this study. Our results showed that, with the Wnt-dependent protocol, cardiac markers were induced but spontaneously contractile cells were not observed. Taken together, our findings show that (1) Wnt signalling may play a role in VPA-induced reprogramming, (2) AFSCs maintained in ESC conditions can better maintain stem cell features, especially osteogenic ability through a TGF-beta/CD73 pathway, (3) With a Wnt-dependent protocol, AFSCs can be induced to express cardiac markers but not to become contractile cells.

description: We investigate the correlations between spectral index, jet side and extent of the radio lobes for a sample of nearby FRII radio galaxies. In Dennett-Thorpe et al. (1997) we studied a sample of quasars and found that the high surface brightness regions had flatter spectra on the jet side (explicable as a result of Doppler beaming) whilst the extended regions had spectral asymmetries dependent on lobe length. Unified schemes predict that asymmetries due to beaming will be much smaller in narrow-line radio galaxies than in quasars: we therefore investigate in a similar manner, a sample of radio galaxies with detected jets. We find that spectral asymmetries in these objects are uncorrelated with jet sidedness at all brightness levels, but depend on relative lobe volume. Our results are not in conflict with unified schemes, but suggest that the differences between the two samples are due primarily to power or redshift, rather than to orientation. We also show directly that hotspot spectra steepen as a function of radio power or redshift. Whilst a shift in observed frequency due to the redshift may account for some of the steepening, it cannot account for all of it, and a dependence on radio power is required.

description: Non-flat fibrations often appear in F-theory GUT models, and their interpretation is still somewhat mysterious. In this note we explore this issue in a model of particular phenomenological interest, the global $SU(5)\times U(1)$ Peccei-Quinn F-theory model. We present evidence that co-dimension three non-flat fibres give rise to higher order couplings in the effective four-dimensional superpotential. More specifically, in our example we find $\mathbf{10}\, \mathbf{5}\, \mathbf{5}\, \mathbf{5}$ couplings.

description: Protein transfection is a versatile tool to study or manipulate cellular processes and also shows great therapeutic potential. However, the repertoire of cost effective techniques for efficient and minimally cytotoxic delivery remains limited. Mesoporous silica nanoparticles (MSNs) are multifunctional nanocarriers for cellular delivery of a wide range of molecules, they are simple and economical to synthesize and have shown great promise for protein delivery. In this work we present a general strategy to optimize the delivery of active protein to the nucleus. We generated a bimolecular Venus based optical sensor that exclusively detects active and bioavailable protein for the performance of multi-parameter optimization of protein delivery. In conjunction with cell viability tests we maximized MSN protein delivery and biocompatibility and achieved highly efficient protein transfection rates of 80%. Using the sensor to measure live-cell protein delivery kinetics, we observed heterogeneous timings within cell populations which could have a confounding effect on function studies. To address this problem we fused a split or dimerization dependent protein of interest to chemically induced dimerization (CID) components, permitting control over its activity following cellular delivery. Using the split Venus protein we directly show that addition of a small molecule dimerizer causes synchronous activation of the delivered protein across the entire cell population. This combination of cellular delivery and triggered activation provides a defined starting point for functional studies and could be applied to other protein transfection methods.
