AMO - TWO-ELEMENT MIXTURE OF BOSE AND FERMI SUPERFLUIDS

By combining ultracold gases of two different elements, new quantum systems may be explored. I will present our realization of a two-element mixture of Bose and Fermi superfluids, a system out of reach with liquid helium mixtures. We use bosonic ytterbium and fermionic lithium, which feature a strong mismatch in mass and distinct electronic properties, and demonstrate elastic coupling between the superfluids by observing the shift in dipole oscillation frequency of the bosonic component due to the presence of the fermions. The measured magnitude of the shift is consistent with a mean-field model and its direction determines the previously unknown sign of the interspecies scattering length to be positive. We also observe the exchange of angular momentum between the superfluids from the excitation of a scissors mode in the bosonic component through interspecies interactions. I will also report on photoassociation spectroscopy in the ytterbium-lithium system, towards the production of ultracold polar molecules with a spin degree of freedom.

With the quantity of generated data ever-increasing in most research areas, conventional data analytics run into solid computational, storage, and communication bottlenecks. These obstacles force practitioners to often use algorithmic heuristics, in an attempt to convert data into useful information, fast. It is necessary to rethink the algorithmic design, and devise smarter and provable methods in order to flexibly balance the trade-offs between solution accuracy, efficiency, and data interpretability. In this talk, I will focus on the problem of low rank matrix inference in large-scale settings. Such problems appear in fundamental applications such as structured inference, recommendation systems and multi-label classification problems. I will introduce a novel theoretical framework for analyzing the performance of non-convex first-order methods, often used as heuristics in practice. These methods lead to computational gains over classic convex approaches, but their analysis is unknown for most problems. This talk will provide precise theoretical guarantees, answering the long-standing question “why such non-convex techniques behave well in practice?” for a wide class of problems. I will discuss implementation details of these ideas and, if time permits, show the superior performance in applications found in physical sciences and machine learning.

This phenomenal growth has sparked new interest in understanding and extending the scope of the field. In this presentation, the growth forecast of AM will be presented. A review of issues associated with direct metal AM will be given which includes part microstructure, defects and mechanical properties. Future trends in metal AM will also be presented. Included will be a current research effort in the presenter’s lab on direct metal processing of commercially interesting aluminum alloys, specifically AA6061.

Design of ssDNA Micelles and Nanotubes for Targeting Cancer

In my group, we design peptide- or aptamer- functionalized nanoparticles for targeting cancer. In this presentation I will discuss our efforts to target a molecule called fractalkine with aptamer-amphiphiles. Fractalkine bears potential for novel therapeutics due to its unique structure and its central role as a mediator of human disease processes such as inflammatory and neoplastic disorders and neurodegenerative diseases. Currently, no therapeutics targeting fractalkine exist. We have recently developed a ssDNA aptamer that binds to fractalkine, and formed micelles out of aptamer-amphiphiles. Our work shows that we can successfully target fractalkine with our ssDNA micelles both in vitro and in vivo in a mouse model of colon cancer, thus providing opportunities to use fractalkine as a molecular target in different diseases. I will also discuss how we design ssDNA-amphiphiles that selfassemble into supramolecular nanostructures with non-spherical geometries, such as ssDNA nanotubes, and how we use these ssDNA nanotubes to target glioblastoma multiforme (GBM), the most common form of primary brain cancer, in vitro and in vivo in an orthotopic mouse model of GBM.

NPP - STAR HIGH LEVEL TRIGGER

We implemented a High-Level Trigger (HLT) system for the STAR experiment to better utilize the luminosity delivered by RHIC. By reconstructing tracks and assembling data from multiple detectors, STAR HLT can select events of great physics interests online, which will reduce the data volume to tape, speed up offline physics analysis and provide vital online monitoring information. In the past a few years, a series of important physics achievements and programs of STAR have benefited from HLT, including the discovery of anti-alpha particles, the first J/\Psi elliptic flow measurement, the Beam Energy Scan program phase I and more recently the STAR heavy flavor tracker and muon telescope detector program. Currently, STAR HLT has 10 times of the computing resources than we had in 2012, which contains about 1200 CPU cores and 45 Xeon Phi (KNC) coprocessors. In this talk, I will discuss the development of STAR HLT, lessons we learned of using such a heterogeneous system and most importantly the physics opportunities opened with these resources.

Floodgates - A composition for full orchestra

Shepherd School of Music

Speaker: Daniel Knaggs

conference room Alice Pratt Brown Hall



The present composition is written in response to the apparently escalating global crises in the political, economic, social, and cultural spheres. The current age finds itself in a sort of permanent warzone, too often seeking solutions in heated rhetoric, arms, and pointing fingers. However, in light of these problems, this work’s objective is not to simply “vent” or dwell in negativity. Instead, it points toward hope in an avenue that that the world has left largely unexplored: that of mercy. In order to musically incorporate the idea of mercy, this work includes quotations from Gregorio Allegri’s “Miserere” (c. 1630), a choral setting of Psalm 51 in which King David takes full responsibility for his crimes and faults while asking for mercy. The composition races through moments of both anxiety and determination, culminating in a climactic moment in which the “floodgates” burst and the orchestra evokes images of torrential downpour along with restatements from Allegri’s “Miserere…” Finally, the present work is left somewhat open-ended or unresolved, in order to not prematurely celebrate what is still left up to the world to live out.

Strain-Sensing Smart Skin for Structural Health Monitoring

Over the past twenty years, many structural health monitoring strategies and damage detection techniques/methods have been proposed. Traditional technologies used for measuring strain, such as resistance strain gages, can monitor only at discrete locations and along specific directions, and have limited ability to measure strains on small length scales. Optical fiber sensors and more specifically fiber Bragg grating (FBG) sensors are also widely used in health monitoring of structures, offering strain and temperature readings. However, practical issues, such as deployment of the optical fibre to the structure and connectors and the high cost of the FBGs, need to be addressed. Some emerging full-filed non-contact strain sensing techniques, such as interferometric techniques, non-interferometric techniques and Raman spectroscopy techniques, have other limitations. A non-contact, full-filed strain sensing technique is needed to perform fast Structural Health Monitoring on structures. In this thesis, the prototype generation of a novel non-contact strain measurement technology is developed using raw HiPco single-walled carbon nanotubes (SWCNTs) and a commercial urethane varnish. This approach exploits the characteristic short-wave infrared fluorescence signatures of semiconducting SWCNTs and the systematic shifts of their fluorescence wavelengths when the nanotubes are axially strained. A strain-sensing smart skin (S4) is prepared by coating the surface to be monitored with a thin film of a composite containing well dispersed SWCNTs embedded in a polymeric host. Strain in the substrate is transmitted through the polymer to the nanotubes, causing systematic and predictable spectral shifts of the nanotube near-infrared fluorescence peak wavelengths. This promising new method should allow quick and precise strain measurements at any position and along any direction of the substrate.

Data centres are the main infrastructures for big data and cloud computing. In our SING lab at HKUST, we have been working on data center networking systems research for years. In this talk, I will start with briefly introducing a lab-scale 100-server data center cluster we built in the last 4 years and some representative networked system projects we implemented based on it. Then, I will elaborate more on the project of multi-level flow scheduling, and its adoption in practice to support real machine learning applications in a large Internet company. At last, I will conclude my talk with the plan on connecting lab research with real-world for more practical impacts.


Hierarchical normal mode refinement of anisotropic thermal parameters for supramolecular complexes

In this thesis, we report a novel normal-mode based protocol for modeling anisotropic thermal motions of supramolecular complexes in x-ray crystallographic refinement, named HNMRef. The method models not only the global movements of the whole complex but also the deformational patterns of substructures. Compared with another widely adopted anisotropic thermal parameters refinement method—multi-group TLS, HNMRef delivers much more accurate thermal parameters for the complex and greatly simplifies the choice of substructure partition schemes. The effectiveness of the procedure is demonstrated on the refinements of a set of complexes with moderate resolutions. This protocol was shown to be able to significantly reduce the values of and improve the electron density maps. Moreover, the distribution of anisotropic thermal ellipsoids was much more consistent throughout the whole structure and agreed with the functional structure movements. We expect this protocol to be very effective in the anisotropic refinements of very large and flexible complexes with low or moderate-resolution x-ray diffraction data.

While the body has an incredible ability to heal, host and external factors may overwhelm its innate regenerative capacity. In these instances, a tissue defect may occur. Tissue defects (regions of either necrotic tissue or void space) are highly susceptible to microbial invasion. Given their proximity to the native micro- and mycobiome, craniofacial and cutaneous defects are at particularly high risk for chronic contamination and infection. The combination of tissue loss and infection creates a negative feedback loop: 1) lack of vascularized healthy tissue leads to a locally immunocompromised area; 2) pathogens are able to colonize the tissue defect and eventually invade the margins of healthy tissue; 3) the resulting pathogenic attack and inflammatory response results in tissue injury and necrosis at the defect border; and 4) the tissue defect expands. Two possible mechanisms to break this cycle are to restore vascularized tissue to the defect site or clear the infection to restore the body’s ability to regenerate tissue. In this dissertation, we seek to develop technologies to treat large tissue defects susceptible to infection through biomaterials-based strategies. First, we investigated and optimized the in vivo bioreactor platform for generating autologous free tissue flaps for mandibular reconstruction. As the engineered tissues grown in these bioreactors are vascularized, their use in mandibular repair restores circulation to the defect site. In a large animal model of disease, we demonstrated that these bioreactors did not require harvested donor tissue, exogenous stem cells, or growth factors in order to generate bony flaps suitable for reconstruction. When transferred to a large mandibular defect in a physiologically-relevant ovine model, these engineered tissues were capable of integrating with the native host tissue for functional craniofacial repair. In the second aim of this work, space maintenance was explored to facilitate the repair of large tissue defects by stimulating the growth of a healthy soft tissue envelope around the defect space as well as functioning as a depot for local delivery of antimicrobial agents to prevent and/or treat infection of the vulnerable large tissue defect. Porous space maintainers were fabricated per good manufacturing practice, subjected to electron beam irradiation, and evaluated for suitability of subsequent mechanical properties. These porous space maintainer devices were then implanted in a superior marginal defect adjacent to the oral mucosa in the mandibular diastema of an ovine model of disease. After nine weeks, space maintainers were removed and the defect was reconstructed with tissue-engineered vascularized flaps generated in 3D-printed bioreactors. Even in a challenging defect environment with proximity to the oral flora and under mechanical load, the space maintainers were able to prevent collapse of tissue into the defect site and maintain a healthy soft tissue envelope for repair. Infection was associated with the single failed case during the use of this strategy. Given the high risk of infection in the setting of large craniofacial defects, econazole-eluting porous space maintainers were developed for the local delivery of an antimicrobial therapeutic during space maintenance. Compared to traditional solid space maintainers, porous space maintainers were able to better inhibit the in vitro growth of common fungal and bacterial pathogens and may be of value in the treatment of tissue defects with infection. Finally, the last aim of this thesis specifically examined novel antifungal approaches for the treatment of infected tissue defects. As there is currently a dearth of animal models of fungal infection relevant to tissue engineering, a murine model with a large cutaneous defect infected with Aspergillus fumigatus was established. A new class of diol-based aliphatic polyesters was synthesized and characterized as polymers whose degradation products have inherent antifungal properties. These diol-based polymers were then fabricated into microparticles and loaded with traditional antifungal therapeutics. After demonstrating extended release of therapeutics in vitro, the microparticles were used to locally treat fungal infection in a large cutaneous defect in an immunocompromised murine model of disease. In sum, this body of work explores biomaterials-based approaches to treat large infected defects, through restoration of tissue and/or by mitigating infection. From leveraging the body’s own innate healing capacity to create vascularized tissue suitable for defect reconstruction (in vivo bioreactors), to utilizing traditional biomaterials in innovative ways (antifungal-eluting bone cement-based space maintainers), to developing new biomaterials with specific antimicrobial applications in mind, we have created a number of strategies to aid in the regeneration of large tissue defects.

Graphene supports surface plasmons that have been observed to be both electrically and geometrically tunable in the midto far-infrared spectral regions. In particular, it has been demonstrated that graphene plasmons can be tuned across a wide spectral range spanning from the mid-infrared to the terahertz. The identification of a general class of plasmonic excitations in systems containing only a few dozen atoms permits us to extend this versatility into the visible and ultraviolet. As appealing as this extension might be for active nanoscale manipulation of visible light, its realization constitutes a formidable technical challenge. We experimentally demonstrate the existence of molecular plasmon resonances in the visible for ionized polycyclic aromatic hydrocarbons (PAHs), which we reversibly switch by adding, then removing, a single electron from the molecule. The charged PAHs display intense absorption in the visible regime with electrical and geometrical tunability analogous to the plasmonic resonances of much larger nanographene systems. Finally, we also use the switchable molecular plasmon in PAHs to demonstrate a proof-of-concept low-voltage electrochromic device.

What happens as light traverses a medium composed of both traditional materials and many ($10^5-10^{12}$ $cm^{-3}$) nanoparticles? These types of systems are present in many active areas of research in the nanotechnology sphere. Examples include nanoparticles in aqueous and non-aqueous solvents during chemical synthesis or for solar energy harvesting applictions; nanoparticles embedded in homogeneous and non-homogeneous solids for photocatalysis; nanoparticles in biological tissue for medical appplications, and more. Because nanoparticles composed of a certain material can have optical properties very different from the bulk material, these types of systems also display unique optical properties. In this thesis I outline an approach to solving light transport in nanomaterial systems. The approach is shown to be useful in many different systems and for a variety of applications.
