Shared-control for systems with constraints
Creators: name: Jiang, Jingjing
Publisher: name: Imperial College London
Year: 2016

description: In the thesis we solve the shared-control problem for three classes of systems: a class of linear mechanical systems, mobile robots and rear wheel drive cars, via full state feedback or output feedback while ensuring that all the state constraints on the closed-loop systems are satisfied. To design the feedback controller for a system with state constraints we firstly remove all the constraints by changing the coordinates through a logarithmic function. Then the back-stepping method is used to design the controller and a Lyapunov-like analysis is used to prove stability properties of the closed-loop system. The shared-control algorithm is based on a hysteresis switch which reduces oscillations when changing the control authority from the human operator to the feedback controller or vice-versa. Unlike other shared-control methods, formal properties of the closed-loop systems with the shared-control have been rigorously established. We start the design of the full state-feedback shared-controller with the assumption that the admissible Cartesian configuration set Pa of the system is a time-invariant convex set defined by a group of linear inequalities. Then the results are extended to the design of shared-controllers via output feedback. In the cases in which only output feedback is available, we can solve the problem by either developing an observer or “remodeling” the system. Through system remodeling we are able to deal with any shape of the admissible configuration set Pa, even time-varying ones. Simulation results help to illustrate how the shared-controller works and show its effectiveness. The state of the closed-loop system with the shared-control never violates the constraints. Experiments done on a mobile robot also demonstrate that the shared-control algorithm works well in practice and meets all safety requirements. In addition, the experimental results match the simulation ones, indicating that the modeling approximations are reasonable and suitable.

Diagnosing, predicting and managing application performance in virtualised multi-tenant clouds
Creators: name: Chen, Xi
Publisher: name: Imperial College London
Year: 2016

description: As the computing industry enters the cloud era, multicore architectures and virtualisation technologies are replacing traditional IT infrastructures for several reasons including reduced infrastructure costs, lower energy consumption and ease of management. Cloud-based software systems are expected to deliver reliable performance under dynamic workloads while efficiently allocating resources. However, with the increasing diversity and sophistication of the environment, managing performance of applications in such environments becomes difficult. The primary goal of this thesis is to gain insight into performance issues of applications running in clouds. This is achieved by a number of innovations with respect to the monitoring, modelling and managing of virtualised computing systems: (i) Monitoring – we develop a monitoring and resource control platform that, unlike early cloud benchmarking systems, enables service level objectives (SLOs) to be expressed graphically as Performance Trees; these source both live and historical data. (ii) Modelling – we develop stochastic models based on Queue- ing Networks and Markov chains for predicting the performance of applications in multicore virtualised computing systems. The key feature of our techniques is their ability to characterise performance bottlenecks effectively by modelling both the hypervisor and the hardware. (iii) Managing – through the integration of our benchmarking and modelling techniques with a novel interference-aware prediction model, adaptive on-line reconfiguration and resource control in virtualised environments become lightweight target-specific operations that do not require sophisticated pre-training or micro-benchmarking. The validation results show that our models are able to predict the expected scalability behaviour of CPU/network intensive applications running on virtualised multicore environments with relative errors of between 8 and 26%. We also show that our performance interference prediction model can capture a broad range of workloads efficiently, achieving an average error of 9% across different applications and setups. We implement this model in a private cloud deployment in our department, and we evaluate it using both synthetic benchmarks and real user applications. We also explore the applicability of our model to both hypervisor reconfiguration and resource scheduling. The hypervisor reconfiguration can improve network throughput by up to 30% while the interference-aware scheduler improves application performance by up to 10% compared to the default CloudStack scheduler.

The search uses the CCD light curves of about 82,000 stars with up to 46 measurements per night over a period of 10 months. No light curve exhibits a form that is consistent with a microlensing event of maximum amplification greater than 1.2. This null result makes it unlikely that the Halo is dominated by objects in the mass range $5 10^{-8}M_{\odot} < M <5 10^{-4}M_{\odot} $. keywords{Galaxy : Halo, kinematics and dynamics, stellar content -- Cosmology : dark matter, gravitational lensing}

description: Objective: This study was conducted to identify the glycosides from petroleum ether and methanol extracts of medicinally and economically useful leaves of Holoptelea integrifolia (Roxb.) planch using high-performance thin layer chromatography (HPTLC) technique. Materials and Methods: Preliminary phytochemical screening was carried out and HPTLC studies were carried out. Camag HPTLC system equipped with Linomat V applicator (Switzerland). Densitometric scanning was performed with Camag TLC scanner IV in the reflectance absorbance mode at 540 nm and operated by Win computer-aided transcription system software (1.4.6 Camag) with the help of tungstant lamp. Results: Preliminary phytochemical screening of petroleum extract of H. integrifolia showed the presence of steroids, terpenoids, alkaloids, glycosides, flavonoids, proteins, tannins and carbohydrates, while methanolic extract of H. integrifolia showed the presence of steroids, alkaloids, flavonoids, proteins, and carbohydrates. HPTLC fingerprinting of glycosides of petroleum ether extract of leaf revealed four polyvalent phytoconstituents (4 peaks) and corresponding ascending order of retention factor (Rf) values in the range of 0.37-0.82. while methanol extract of leaf showed ten polyvalent phytoconstituents (10 peaks) and corresponding ascending order of Rf values in the range of 0.20-0.83. Conclusions: With the above Rf values and preliminary phytochemical analysis we have concluded the presence of glycosides in both the extracts. The present study revealed that the plant H. integrifolia is a good source of phytochemicals.

description: In this work we incorporate the newest ISO results on the mid-infrared spectral-energy-distributions (MIR SEDs) of galaxies into models for the number counts and redshift distributions of MIR surveys. A three-component model, with empirically determined MIR SED templates of (1) a cirrus/PDR component (2) a starburst component and (3) an AGN component, is developed for infrared (3--120\micron) SEDs of galaxies. The model includes a complete IRAS 25\micron selected sample of 1406 local galaxies ($z \leq 0.1$; Shupe et al. 1998a). Results based on these 1406 spectra show that the MIR emission features cause significant effects on the redshift dependence of the K-corrections for fluxes in the WIRE 25\micron band and ISOCAM 15\micron band. This in turn will affect deep counts and redshift distributions in these two bands, as shown by the predictions of two evolution models (a luminosity evolution model with $L\propto (1+z)^3$ and a density evolution model with $ρ\propto (1+z)^4$). The dips-and-bumps on curves of MIR number counts, caused by the emission features, should be useful indicators of evolution mode. The strong emission features at $\sim 6$--8\micron will help the detections of relatively high redshift ($z\sim 2$) galaxies in MIR surveys. On the other hand, determinations of the evolutionary rate based on the slope of source counts, and studies on the large scale structures using the redshift distribution of MIR sources, will have to treat the effects of the MIR emission features carefully. We have also estimated a 15\micron local luminosity function from the predicted 15\micron fluxes of the 1406 galaxies using the bivariate (15\micron vs. 25\micron luminosities) method. This luminosity function will improve our understanding of the ISOCAM 15\micron surveys.

Slides: Robust Gridless Estimation of Angles and Delays for Full-Dimensional Wideband mmWave Channels
Creators: Yuan-Pei Lin

SPS Webinar, 15 May 2024, Dr. Yuan-Pei Lin
For many gridless angle estimation methods of mmWave channels,  the channel gains needs to be time-invariant during training.  This presentation introduces a method that is applicable to both time-invariant and time-varying channels, and robust to channel variations.
This is done by employing time-varying precoders and combiners that are banded block Toeplitz (BBT) matrices.  The advantage of time-varying BBT precoders is two-fold. First, with time-varying  BBT precoding we can fabricate time-varying channels.   Thus the channel can be estimated as if it is a time-varying channel whether the actual channel is time-varying or not.  We will show that, thanks to fabricated time variation in the channel, a small training overhead can be used.  Secondly, BBT precoding and combining preserve the shift invariance property of the received data matrix.  Due to the preservation of shift invariance property, we can employ most existing direction finding methods for estimating the angles and delays, including low complexity gridless subspace based algorithms.   Simulation results are given to show that the proposed time-varying BBT precoding provides robust and accurate channel estimates with a low complexity.

In this talk, we present an outline of a powerful Bayesian estimation framework we call "Plug-and-Play Priors" (PnP). We invented this family of algorithms (including "consensus equilibrium") to solve large-scale ill-posed inverse problems, particularly focusing on computational imaging applications. At its core, PnP is powerful because it allows for off-the-shelf denoisers and other ML models and filters to be used as Bayesian prior models. In our original work, we built out PnP on top of alternating direction method of multipliers (ADMM), but several researchers have since adapted our methods to other frameworks such as FISTA. We also present theoretical conditions on these off-the-shelf models and filters (used as priors) to ensure PnP iterates converge. Through these theoretical guarantees, Plug-and-Play has indeed come a long way from what could very well have been "Plug-and-Pray". We will also talk about several imaging examples that demonstrate what PnP has been able to achieve, and why it has spawned a new sub-area of computational imaging. We end the talk with mentions of some surprising-and-impressive applications and extensions other researchers have achieved, as they have built on top of our original PnP algorithm.

description: In this manuscript we study the following optimization problem with volume constraint: \[ \min\left\{\frac{1}{p}\int_Ω |\nabla v|^pdx- \int_{\partial Ω} gv\,dS \colon v \in W^{1, p} \left(Ω\right), \text{ and } |\{v>0\}| \leq α\right\}. \] Here $g$ is acontinuous function and $α$ is a fixed constant such that $0< α< |Ω|$. Under the assumption that $\displaystyle \int_{\partial Ω} g(x)dS >0$ we prove that a minimizer exists and satisfies $$ \left\{ \begin{array}{ccl} -Δ_p u_p = 0 &\text{in } &\{u_p>0\} \cup \{u_p<0\}, \\[5pt] |\nabla u_p|^{p-2}\frac{\partial u_p}{\partial ν} = g & \text{on } &\partial Ω \cap\partial(\{u_p>0\} \cup \{u_p<0\} ) ,\\[5pt] |\{u_p>0\}| = α. & & \end{array} \right. $$ Next, we analyze the limit as $p\to \infty$. We obtain that any sequence of weak solutions converges, up to a subsequence, $\lim\limits_{p_j \to \infty} u_{p_j}(x)=u_{\infty}(x)$, uniformly in $\overlineΩ$, and uniform limits, $u_\infty$, are solutions to the maximization problem with volume constraint $$ \max\left\{ \int_{\partial Ω} gv\,dS \colon v \in W^{1, \infty} \left(Ω\right), \|\nabla v\|_{L^{\infty}(Ω)}\leq 1 \text{ and }|\{v>0\}| \leq α\right\}. $$ Furthermore, we obtain the limit equation that is verified by $u_\infty$ in the viscosity sense. Finally, it turns out that such a limit variational problem is connected to the Monge-Kantorovich mass transfer problem with the involved measures are supported on $\partial Ω$ and along the limiting free boundary, $\partial \{u_{\infty} \neq 0\}$.

description: We study the shadows cast by near-extremal Kerr-MOG black holes for different values of the parameter in modified gravity (MOG). In particular, we consider an isotropic emitter orbiting near such black holes and analytically compute the positions, fluxes and redshift factors of their images. The size of the shadow decreases when the modified parameter is increased. For each shadow, the images of the emitter appear on a special part of the shadow which has a rich structure. The primary image and secondary images are similar to those produced for the near-extremal (high spin) Kerr black hole, but the near-extremal Kerr-MOG black hole can have a spin ($\hat{J}/M^2_α$) which is finitely lower than 1. When the modified parameter is varied, the typical positions of the corresponding images do not change, nor does the typical redshift factor associated with the primary image. However, another typical redshift factor associated with the secondary image increases when the modified parameter is increased. We also find that the fluxes increase in that case. These images appear periodically with period greater than that of Kerr. This provides an alternative signature away from the Kerr case which may be tested by the Event Horizon Telescope.

description: In his Legends of The Konkan, Crawford narrates a folk tale read out to him by an old Bhat from Chiplun, which inter alia describes the peopling of Kōnkaṇ. The first to arrive were the dhangars (herdsmen) of the ghatmala; every year they came with their buffaloes and penetrated further till they overran the payeen ghauts (foot hills). Beyond that was the paradise : mighty rivers, magnificent forests of every kind of valuable timber, trees laden with delicious fruits, a coast line fringed with coconut palms, lush forage on every hillside and wild rice growing in all the valleys. Those that returned to their upland homes gave marvelous accounts of their new discovery. Attracted by these tales, the hardy mhar of the Dekkhan ventured to explore. They built there huts walled with split bamboos and red clay, and roofed them with woven coconut palms. They hired bands of cultivators from above the ghats, sudra by caste, to till the land lying all around. Vaishya followed them and carried the produce up-ghat on bullock carts driven by brinjaris (gypsies) from the far east Dekkhan. The kshatrya from across the ghats came thereafter. But, with the exception of a few Brahmins occasionally summoned by the ryots to officiate at religious ceremonies, none of the brāhman ventured to make their permanent residence in Kōnkaṇ.

description: We use numerical simulations to test the feasibility of the suggestion by Ibata et al. (1994) that the excess population of stars which they discovered in the Sagittarius region may be the disrupted remains of a dwarf spheroidal galaxy. We find that a Fornax-like model for the pre-disruption system can indeed reproduce the data. However, the galaxy must be on a relatively short period orbit with a pericentre of about $10$ kpc and an apocentre of about $52$ kpc, giving a current transverse velocity of $255$ km/s and a period of $\sim 760$ Myr. Furthermore, disruption must have occurred predominantly on the last pericentric passage rather than on the present one. The data are consistent with transverse motion either towards or away from the Galactic Plane. These results depend primarily on the rotation curve of the Galaxy and are insensitive to the mass distribution in its outer halo or to the mass of its disk.

description: We compute double and triple inclusive gluon production in p-A scattering beyond the so-called "glasma graph" approximation. We consider quantum interference effects and identify in this general setup the terms responsible for the gluon HBT and initial wave function Bose enhancement which lead to correlations in particle production. Both of these terms originate from the factorizable part of the quadrupole and sextupole terms in the production cross section. We also show that the target Bose enhancement in this regime is suppressed at large number of colors.

Stellar Gas Flows Into A Dark Cluster Potential At The Galactic Center
Creators: name: Melia, Fulvio

Publisher: name: arXiv
Year: 1998
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The evidence for the presence of a concentration of dark matter at the Galactic center is now very compelling. There is no question that the stellar and gas kinematics within 0.01 pc is dominated by under-luminous matter in the form of either a massive black hole, a highly condensed distribution of stellar remnants, or a more exotic source of gravity. The unique, compact radio source Sgr A* appears to be coincident with the center of this region, but its size (less than 3x10^14 cm at lambda=1.35cm) is still significantly smaller than the current limiting volume enclosing this mass. Sgr A* may be the black hole, if the dark matter distribution is point-like. If not, we are left with a puzzle regarding its nature, and a question of why this source should be so unique and lie only at the Galactic center. Here, we examine an alternative to the black hole paradigm---that the gravitating matter is a condensed cluster of stellar remnants---and study the properties of the Galactic center wind flowing through this region. Some of this gas is trapped in the cluster potential, and we study in detail whether this hot, magnetized gas is in the proper physical state to produce Sgr A*'s spectrum. We find that at least for the Galactic center environment, the temperature of the trapped gas never attains the value required for significant GHz emission. In addition, continuum (mostly bremsstrahlung) emission at higher frequencies is below the current measurements and upper limits for this source. We conclude that the cluster potential is too shallow for the trapped Galactic center wind to account for Sgr A*'s spectrum, which instead appears to be produced only within an environment that has a steep-gradient potential like that generated by a black hole.

Gait analysis using an instrumented treadmill
Creators: name: Wiik, Anatole Vilhelm
Publisher: name: Imperial College London
Year: 2016

description: Background: Gait analysis is used to measure objectively the ability to walk before and after hip and knee joint replacement. Most gait literature to date has measured patients walking at slow speeds, which may have unintentionally characterized successful lower limb operations as the same regardless of its operation type. The aim of this thesis was to use an instrumented treadmill to (1) test the upper limits of gait performance of patients awaiting and after lower limb arthroplasty and (2) describe and compare different joint procedures to healthy controls. Method: Gait analysis was carried out using an instrumented treadmill. Study participants walked at their preferred walking and top walking speed on the treadmill. Their vertical ground reaction force and spatiotemporal data was captured for both limbs by tandem force plates beneath the treadmill’s belt. Results: The results suggest that at preferred walking speed on the flat, all subjects’ gait characteristics were similar irrespective of joint state. The differences between patient groups became more apparent at top walking speed. Weight acceptance, step length and stride length were the most useful variables assessing these differences. Unicompartmental knee replacement and hip resurfacing had closer to normal gait patterns when compared to total knee replacement and conventional total hip replacement respectively. Predictably patients with knee osteoarthritis had asymmetrical gait patterns, impulse was found to be the best variable distinguishing patients with knee osteoarthritis from healthy controls. The downhill walking assessment established that patients with unicompartmental knee replacements had a more normal gait pattern than total knee replacement patients. Conclusion: The gait results suggest that an instrumented treadmill is a useful metric to describe patient gait patterns. Testing performance at higher walking speeds allowed differences to be detected, which were undetectable at slower speeds. Anatomically conserving procedures such as unicompartmental knee replacement and hip resurfacing appear to have convincing functional advantages compared to less conserving joint replacement procedures.

Tool development to study ubiquitination machinery
Creators: name: Ward, Jennifer
Publisher: name: Imperial College London
Year: 2016

description: Ubiquitination is a diverse post-translational modification, involved in a plethora of eukaryotic processes. At least three different enzymes are required for ubiquitination to occur: an ubiquitin-activating enzyme (E1), an ubiquitin-conjugating enzyme (E2) and an ubiquitin ligase (E3). Conversely, deubiquitinating enzymes (DUBs) regulate the removal of ubiquitin modifications. Together, this enzymatic machinery facilitates a wide array of ubiquitin modifications and further ubiquitin-like modifications. Such modifications play a significant role in the regulation of vital biological processes including proteasomal degradation, DNA damage response (DDR) and NF-κB signalling. Ubiquitination machinery can be studied using a chemical proteomics approach. Activity-based probes (ABPs) which covalently trap enzymes can be employed. Such probes possess bioorthogonal handles, which on ligation to complementary reporter groups enable enrichment of probe-enzyme complexes prior to LC-MS/MS, western blot, or fluorescent analysis. The design, synthesis, and development of six inhibitor-inspired ABPs for ubiquitin machinery is described. Both small molecule and peptide probes were explored, and assessed for their ability to act as ubiquitin machinery probes both in intact cells and cell lysate. Spike-in SILAC methodology was employed to quantify probe targets under competitive conditions against parent inhibitors, and in a DNA damage response model. An alternative to using literature inhibitors is to derive novel starting points for tool design through a fragment-based drug discovery approach. A high throughput screen against the minimal catalytic core of HOIP, an E3 ligase, is described together with subsequent validation and characterisation of hit fragments by waterLOGSY NMR and Micro-scale thermophoresis, and crystallography attempts. Finally, a model system for the structural analysis of transient enzyme complexes is explored, to further our understanding of these interactions and ultimately to assess the applicability of these complexes for future drug discovery. The design and synthesis of a maleimide trap is described, along with its application to covalently trap an Ub-E2-E3 complex.
Comprehensive study of large-area CVD graphene field effect structures at DC and microwave frequencies
Creators: name: Adabi, Mohammad
Publisher: name: Imperial College London

description: Following the successful isolation of graphene in 2004 by Novoselov and Geim, a significant amount of time and energy have been invested in studying the properties of this 2D material. Many researchers and companies from all around the world have established the vision of incorporating graphene into industrial scale applications where full utilisation of this material can be achieved outside the laboratories. One of the major technical challenges facing electrical characterisation of graphene is the different processes such as lithography and plasma etching that this material has to be exposed to before an electrical measurement can be conducted on it. These processes are known to partially deteriorate the inherent properties of graphene. A potential solution is to employ a contact-free electrical measurement technique where transport properties of large-area graphene films can be extracted without the need for realization of contacts to the surface of graphene. This thesis explores a microwave resonance technique to study the field effect properties of graphene based field effect structures. Field effect devices with a variety of dielectric films are fabricated and performance of each of them is analysed separately. This microwave method will prove to be consistent with the DC measurements and also in perfect agreement with the theoretical results from the Boltzmann equation. Further to successful demonstration of the microwave cavity technique, a novel stacked heterostructure of graphene-aluminum nitride-graphene is designed and developed. It will be shown that the sheet resistance of one graphene layer in such structure can be modulated by the application of a gate voltage to another graphene layer. This system resembles a parallel circuit of the two graphene films where each layer has a distinct doping level. The Boltzmann’s framework is used and the obtained microwave field effect conductivity result are accompanied by a fitting model. Switching ratio of as high as 4.5 is achieved at room temperature by controlling the doping level in each graphene sheet. This heterostructure system presents a promising new device structure that can potentially be used as a dual-biosensing device for biomedical applications. Such device could utilise the piezoelectric properties of aluminium nitride in combination with the strength, conductivity, transparency, and bio-compatibility of graphene to detect and measure the mass as well as the charge of various cells including the cancer cells. The dual-sensing mode is expected to significantly improve the false negatives that are currently obtained via other cell capturing methods.

description: Large-scale water transfer projects (LWTPs) have been promoted to address rising water demands around the world. Scholars have been examining various impacts of LWTPs for decades; however, there is limited research that systematically examines the literature and synthesizes impacts and lessons learned from LWTPs. By conducting a systematic literature review, we assess the impacts of LWTP implementation on communities followed by the social, political, and economic factors that shape the implementation of LWTPs. Our review indicates that LWTPs can threaten livelihood strategies, jeopardize the sustainability of traditional cultures, and disrupt communities through resettlement. These impacts are shaped by the use of water as a political mechanism, the prioritization of economic interests, and unequal participation of stakeholders. Our review goes beyond individual studies of LWTPs to highlight the importance of using an environmental justice framework to guide LWTP assessments so that these assessments can address unique contexts of individual LWTPs.

Replaced synonym: Cytisus pinnatus L. (1753).
Lectotype (Smith, Fl. Vitiensis Nova 3: 170. 1985): [icon] " Phaseolo affinis Arbor Indica Coral dicta polyphyllos non spinosa, foliis mollibus subhirsutis " in Plukenet, Phytographia: t. 104, f. 3. 1691; Almag. Bot.: 293. 1696.
Current name: Millettia pinnata (L.) Panigrahi (Fabaceae: Faboideae).
Note: Merrill (in Philipp. J. Sci., C, 5: 101. 1910) took up this name in place of Cytisus pinnatus L. (1753) and interpreted R. mitis via Herb. Linn. No. 913.3 (LINN). Robinia mitis is, however, an illegitimate renaming of C. pinnatus and consequently the two names are homotypic. Although annotated with “mitis” by Linnaeus, sheet 913.3 (LINN) is not original material for C. pinnatus. Smith appears to have been the first to make a formal choice of type for C. pinnatus (and hence R. mitis).

description: Although studies over the years have sought to understand the impacts of protected areas on surrounding communities, only limited research has explored these impacts from a gender perspective. Drawing from primary data collected from semi-structured interviews and focus group discussions in the Mole National Park, Ghana, and ten of its surrounding communities, this study assesses the differences in impacts arising from nature conservation on both men and women to determine how such differences affect how specific gender groups respond to collaborative natural resources management interventions. Results show that men primarily suffer economic impacts from conservation while women suffer both economic and socio-psychological impacts. Socio-cultural norms and practices further exacerbate the impacts of conservation on women resulting in negative attitudes of women toward conservation. This has serious consequences for women's participation in the collaborative management of protected areas and conservation goals in general.
Optimal operating protocol to achieve efficiency at maximum power of heat engines

description: The efficiency at maximum power has been investigated extensively, yet the practical control scheme to achieve it remains elusive. We fill such gap with a stepwise Carnot-like cycle, which consists the discrete isothermal process (DIP) and adiabatic process. With DIP, we validate the widely adopted assumption of \mathscr{C}/t relation of the irreversible entropy generation S^{(\mathrm{ir})}, and show the explicit dependence of the coefficient \mathscr{C} on the fluctuation of the speed of tuning energy levels as well as the microscopic coupling constants to the heat baths. Such dependence allows to control the irreversible entropy generation by choosing specific control schemes. We further demonstrate the achievable efficiency at maximum power and the corresponding control scheme with the simple two-level system. Our current work opens new avenues for the experimental test, which was not feasible due to the lack the of the practical control scheme in the previous low-dissipation model or its equivalents.

Unambiguous quasar microlensing

Publisher: name: arXiv
Year: 1998
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Microlensing studies of quasars can reveal dark matter lumps over a broad mass spectrum; we highlight the importance of monitoring quasars which are seen through the halos of low-redshift galaxies. For these configurations microlensing by planetary-mass objects will manifest itself as isolated events which are only weakly chromatic. Statistical comparison of the observed optical depths with their theoretical counterparts provides a strong test for a microlensing origin of such events. If microlensing is detected, the light-curves can reveal not only the characteristic microlens masses, and their corresponding contribution to dark halos, but also how compact the individual objects are. In this way we can decisively test the possibility that the dark matter associated with galaxies is composed principally of planetary-mass gas clouds.

A Stratonovich-Skorohod integral formula for Gaussian rough paths
Creators: name: Lim, Nengli
Publisher: name: Imperial College London
Year: 2016

description: Given a Gaussian process $X$, its canonical geometric rough path lift $\mathbf{X}$, and a solution $Y$ to the rough differential equation $\mathrm{d}Y_{t} = V\left (Y_{t}\right ) \circ \mathrm{d} \mathbf{X}_t$, we present a closed-form correction formula for $\int Y_t \circ \mathrm{d} \mathbf{X}_t - \int Y_t \, \mathrm{d} X_t$, i.e. the difference between the rough and Skorohod integrals of $Y$ with respect to $X$. When $X$ is standard Brownian motion, we recover the classical Stratonovich-to-It{\^o} conversion formula, which we generalize to Gaussian rough paths with finite $p$-variation for $1 \leq p < 3$, and Volterra Gaussian rough paths for $3 \leq p < 4$. This encompasses many familiar examples, including fractional Brownian motion with $H > \frac{1}{4}$. It\^{o}'s formula can also be recovered in the case when $Y_t = \nabla f( X_t)$ for some smooth $f$. \par To prove the formula, we show that $\int Y_t \, \mathrm{d} X_t$ is the $L^2(\Omega)$ limit of its Riemann-sum approximants, and that the approximants can be appended with a suitable compensation term without altering the limit. To show convergence of the Riemann-sum approximants, we utilize a novel characterization of the Cameron-Martin norm using multi-dimensional Young-Stieltjes integrals. For the main theorem, complementary regularity between the Cameron-Martin paths and the covariance function of $X$ is used to show the existence of these integrals. However, it turns out not to be a necessary condition, as we provide a new set of conditions for their existence, as well as provide a new formulation of the classical It\^{o}-Skorohod isometry in terms of these Young-Stieltjes integrals.
