Space-Time Behavior Based Correlation (2005)

We introduce a behavior-based similarity measure which tells us whether two different space-time intensity patterns of two different video segments could have resulted from a similar underlying motion field. This is done directly from the intensity information, without explicitly computing the underlying motions. Such a measure allows us to detect similarity between video segments of differently dressed people performing the same type of activity. It requires no foreground/background segmentation, no prior learning of activities, and no motion estimation or tracking. Using this behavior-based similarity measure, we extend the notion of 2-dimensional image correlation into the 3-dimensional space-time volume, thus allowing to correlate dynamic behaviors and actions. Small space-time video segments (small video clips) are "correlated" against entire video sequences in all three dimensions (x,y, and t). Peak correlation values correspond to video locations with similar dynamic behaviors. Our approach can detect very complex behaviors in video sequences (e.g., ballet movements, pool dives, running water), even when multiple complex activities occur simultaneously within the field-of-view of the camera.
Capacity issues in digital image watermarking (2002)

We study certain aspects of the problem of watermarking images, not for the classical example of ownership identification, but instead for embedding a unique identifier that can act as a "serial number" for the image in which it is embedded. In this context, two fundamental questions are: (a) what is the maximum number of different watermarks that can be distinguished reliably? and (b) what are good design techniques for watermarking methods to approximate that maximum? Under the assumption that attacks can be modeled as additive noise, we provide answers to both questions. To answer (a), we first show how the process of inserting a watermark is analogous to that of storing bits in certain devices, and then we compute the storage capacity of these devices. To answer (b), we present a specific design of a modulator to store information in those devices. Numerical simulations reveal that although strongly suboptimal in the number of bits they can effectively store in an image, simple and very low complexity modulator designs are able to pack enough bits in an image to be useful in practice.
Choosing useful word alternates for automatic speech recognition correction interfaces (2014)

Speech recognition is an increasingly important input modality, especially for mobile computing. Because errors are unavoidable in real applications, efficient correction methods can greatly enhance the user experience. In this paper we study a reranking and classification strategy for choosing word alternates to display to the user in the framework of a tap-to-correct interface. By employing a logistic regression model to estimate the probability that an alternate will offer a useful correction to the user, we can significantly reduce the average length of the alternates lists generated with no reduction in the number of words they are able to correct.
Infrared micro-spectral imaging: distinction of tissue types in axillary lymph node histology (2008)

This paper provides strong evidence that automated diagnosis by means of infrared micro-spectral imaging is possible. Recent investigations within the author's laboratory upon lymph nodes have also revealed that cancers from different primary tumours provide distinctly different spectral signatures. Thus poorly differentiated and hard-to-determine cases of metastatic invasion, such as micrometastases, may additionally be identified by this technique. Finally, we differentiate benign and malignant tissues composed within axillary lymph nodes by completely automated methods of spectral analysis.
The sample tree: a sequential hypothesis testing approach to 3D object recognition (2002)

A method is presented for efficient and reliable object recognition within noisy, cluttered, and occluded range images. The method is based on a strategy which hypothesizes the intersection of the object with some selected image point, and searches for additional surface data at locations relative to that point. At each increment, the image is queried for the existence of surface data at a specific spatial location, and the set of possible object poses is further restricted. Eventually, either the object is identified and localized, or the initial hypothesis is refuted. The strategy is implemented in the discrete domain as a binary decision tree classifier. The tree leaf nodes represent individual voxel templates of the model. The internal tree nodes represent the union of the templates of their descendant leaf nodes. The union of all leaf node templates is the complete template set of the model over its discrete pose space. Each internal node also references a single voxel which is the most common element of its child node templates. Traversing the tree is equivalent to efficiently matching the large set of templates at a selected image seed location. The process is approximately 3 orders of magnitude more efficient than brute-force template matching. Experimental results are presented in which objects are reliably recognized and localized in 6 dimensions in less than 60 seconds within noisy and significantly occluded range images.

The surface plasmon resonance biosensor assay offers a rapid system for directly measuring antibody levels in serum without the use of any labels, while comparing favorably with the ELISA system in sensitivity and specificity.
CAPS: Energy-Efficient Processing of Continuous Aggregate Queries in Sensor Networks (2006)

In this paper, we design and evaluate an energy efficient data retrieval architecture for continuous aggregate queries in wireless sensor networks. We show how the modification of precision in one sensor affects the sample-reporting frequency of other sensors, and how the precisions of a group of sensors may be collectively modified to achieve the target quality of information (QoI) with higher energy-efficiency. The proposed collective adaptive precision setting (CAPS) architecture is then extended to exploit the observed temporal correlation among successive sensor samples for even greater energy efficiency. Detailed simulations with synthetic and real data traces demonstrate how the combination of weak consistency semantics and temporal correlation can dramatically lower the energy consumption in practical sensor environments
A 26.5-to-40-GHz Planar Balanced Mixer (1975)

The design and performance of a MIC 26.5-40 GHz mixer is described. The mixer utilizes GaAs beam lead Schottky barrier diodes with a cutoff frequency of 750 GHz in a balanced arrangement with slot-line and coplanar waveguide. Conversion loss for the full waveguide band is 7.6 ± 0.5 dB with + 6 dBm LO drive. VSWRs are less than 2:1 for the RF port and 3.4:1 for the LO port. The mixer exhibits excellent LO to RF isolation, typically 25 dB and handles IF frequencies up to 8 GHz.

Nanosilver composite pNIPAm microgels for the development of antimicrobial platelet‐like particles (2020)

Platelets crucially facilitate wound healing but can become depleted in traumatic injury or chronic wounds. Previously, our group developed injectable platelet-like particles (PLPs) comprised of highly deformable, ultralow crosslinked pNIPAm microgels (ULCs) coupled to fibrin binding antibodies to treat post-trauma bleeding. PLP fibrin-binding facilitates homing to sites of injury, promotes clot formation, and, due to high particle deformability, induces clot retraction. Clot retraction augments healing by increasing clot stability, enhancing clot stiffness, and promoting cell migration into the wound bed. Because post-traumatic healing is often complicated by infection, the objective of these studies was to develop antimicrobial nanosilver microgel composite PLPs to augment hemostasis, fight infection, and promote healing post-trauma. A key goal was to maintain particle deformability following silver incorporation to preserve PLP-mediated clot retraction. Clot retraction, antimicrobial activity, hemostasis after trauma, and healing after injury were evaluated via confocal microscopy, colony-forming unit assays, a murine liver trauma model, and a murine full-thickness injury model in the absence or presence of infection, respectively. We found that nanosilver incorporation does not affect base PLP performance while bestowing significant antimicrobial activity and enhancing infected wound healing outcomes. Therefore, Ag-PLPs have great promise for treating hemorrhage and improving healing following trauma.
Single-view hair modeling for portrait manipulation (2012)

Human hair is known to be very difficult to model or reconstruct. In this paper, we focus on applications related to portrait manipulation and take an application-driven approach to hair modeling. To enable an average user to achieve interesting portrait manipulation results, we develop a single-view hair modeling technique with modest user interaction to meet the unique requirements set by portrait manipulation. Our method relies on heuristics to generate a plausible high-resolution strand-based 3D hair model. This is made possible by an effective high-precision 2D strand tracing algorithm, which explicitly models uncertainty and local layering during tracing. The depth of the traced strands is solved through an optimization, which simultaneously considers depth constraints, layering constraints as well as regularization terms. Our single-view hair modeling enables a number of interesting applications that were previously challenging, including transferring the hairstyle of one subject to another in a potentially different pose, rendering the original portrait in a novel view and image-space hair editing.

Magnetic shielding of Hall thrusters at high discharge voltages (2014)

A series of numerical simulations and experiments have been performed to assess the effectiveness of magnetic shielding in a Hall thruster operating in the discharge voltage range of 300–700 V (Isp ≈ 2000–2700 s) at 6 kW, and 800 V (Isp ≈ 3000) at 9 kW. At 6 kW, the magnetic field topology with which highly effective magnetic shielding was previously demonstrated at 300 V has been retained for all other discharge voltages; only the magnitude of the field has been changed to achieve optimum thruster performance. It is found that magnetic shielding remains highly effective for all discharge voltages studied. This is because the channel is long enough to allow hot electrons near the channel exit to cool significantly upon reaching the anode. Thus, despite the rise of the maximum electron temperature in the channel with discharge voltage, the electrons along the grazing lines of force remain cold enough to eliminate or reduce significantly parallel gradients of the plasma potential near the walls. Computed maximum erosion rates in the range of 300–700 V are found not to exceed 10−2 mm/kh. Such rates are ∼3 orders of magnitude less than those observed in the unshielded version of the same thruster at 300 V. At 9 kW and 800 V, saturation of the magnetic circuit did not allow for precisely the same magnetic shielding topology as that employed during the 6-kW operation since this thruster was not designed to operate at this condition. Consequently, the maximum erosion rate at the inner wall is found to be ∼1 order of magnitude higher (∼10−1 mm/kh) than that at 6 kW. At the outer wall, the ion energy is found to be below the sputtering yield threshold so no measurable erosion is expected.

New association of surfactants for the production of food and cosmetic nanoemulsions: preliminary development and characterization (2011)

A new nanoemulsifing system has been developed. This study refers to an innovative association of polysorbate 80 and palmitic ester of l-ascorbic acid for the production of good stability and very thin nanostructured emulsions with average micellar diameter size ranging from 100 to 300 nm. This system has showed to be very performing to create nanoemulsions with moderate stirring rate and warming regimen thanks to the high efficiency of the association between ascorbyl palmitate and polysorbate-80 (PS-80). This nanoemulsified system is very easy to achieve and shows a very good capability to encapsulate several substrates of both nutritional and cosmetic usage such as melatonin, resveratrol, essential oils and steroidic terpenes such as boswellic acids and others. This system has been optimally applied to nutraceutical and cosmetic formulations and particularly to develop sprayable sublingual delivery systems for melatonin and the aforesaid molecules. This study describes developing and analytical characterization of this system containing melatonin. Un nouveau système de nano émulsification a été développé.

Radially Classified Aerosol Detector for Aircraft-Based Submicron Aerosol Measurements (1996)

A radially classified aerosol detector (RCAD) for fast characterization of fine particle size distributions aboard aircraft has been designed and implemented. The measurement system includes a radial differential mobility analyzer and a high-flow, high-efficiency condensation nuclei counter based on modifications to a commercial model (TST, model 3010). Variations in pressure encountered during changes in altitude in flight are compensated by feedback control of volumetric flow rates with a damped proportional control algorithm. Sampling resolution is optimized with the use of an automated dual-bag sampling system. This new system has been tested aboard the University of Washington Cl31a research aircraft to demonstrate its in-flight performance capabilities. The system was used to make measurements of aerosol, providing observations of the spatial variability within the cloud-topped boundary layer off the coast of Monterey, California.
A flexible layered LDPC decoder (2011)

We introduce a flexible layered decoder architecture for Quasi-Cyclic Low Density Parity Check (LDPC) codes. An iterative construction of the parity check matrix is exploited by the proposed decoder to achieve various degrees of parallelism, characterized by a high utilization of variable and check processing nodes, absence of memory conflicts, and a simple and scalable interconnection network. Furthermore, the proposed LDPC decoder supports variable code rate, information-word length and order of modulation. A comparison to prior-art decoders proves the efficiency of the proposed scheme.
Large capacity multiaccess optical packet network (1994)

A multiaccess optical packet network capable of providing multigigabit-per-second transmission per user is presented. The proposed system is based on wavelength division multiplexing and frequency routing. It is optically transparent, has no internal blocking, and is optically self-routing. Users freely transmit their packets. Collision-free reception is achieved by means of a novel fast-tunable optical filter that controls the packet flow. Reception acknowledgments are passively generated without the use of optical sources and are transported on the same packet network. Assuming a single transmitter per user, and either one or two receivers (each with its own fiber) per user, the system throughput can approach 60% and 90% (per wavelength), respectively.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
On Variable Constraints in Privacy Preserving Data Mining (2005)

In recent years, privacy preserving data mining has become an important problem because of the large amount of personal data which is tracked by many business applications. In many cases, users are unwilling to provide personal information unless the privacy of sensitive information is guaranteed. A recent framework performs privacy preserving data mining by using a condensation based approach. In this framework, the privacy of all records is treated homogeneously. It is therefore inefficient to design a system with a uniform privacy requirement over all records. We discuss a new framework for privacy preserving data mining, in which the privacy of all records is not the same, but can vary considerably. This is often the case in many real applications, in which different groups of individuals may have different privacy requirements. We discuss a condensation based approach for privacy preserving data mining in which an efficient method is discussed for constructing the condensation in a heterogeneous way. The heterogeneous condensation is capable of handling both static and dynamic data sets. We present empirical results illustrating the effectiveness of the method.

Insulin-Like Growth Factor Receptor Type I as a Target for Cancer Therapy (2009)

In recent years, improvements in the understanding of oncogenesis has permitted the identification of new molecular targets for cancer therapy. Among all the different approaches, inhibition of tyrosine kinase receptor activity using small molecules or biomolecules for controlling cancer growth has been successful and has brought new therapeutic opportunities to the medical community. After more than 20 years of extensive work, insulin-like growth factor receptor I (IGF-IR) is becoming an attractive target for drug development. Owing to its close homology to insulin receptor, IGF-IR is of interest for antibody design while its specificity allows us to discriminate between the two receptors. Major efforts from a large number of pharmaceutical companies are invested in evaluating the efficacy of such molecules in humans. Discovery of biomarkers associated with efficacy and patient selection are the main challenges that we will have to deal with in order to target the appropriate patient population that will most benefit from anti-IGF-IR monoclonal antibodies and combined treatments. This review will provide an overview of the current knowledge on IGF-IR and ongoing clinical trials.
