Director orientations in lyotropic liquid crystals: diffusion MRI mapping of the Saupe order tensor (2016)

The macroscopic physical properties of a liquid crystalline material depend on both the properties of the individual crystallites and the details of their spatial arrangement. We propose a diffusion MRI method to estimate the director orientations of a lyotropic liquid crystal as a spatially resolved field of Saupe order tensors. The method relies on varying the shape of the diffusion-encoding tensor to disentangle the effects of voxel-scale director orientational order and the local diffusion anisotropy of the solvent. Proof-of-concept experiments are performed on water in lamellar and reverse hexagonal liquid crystalline systems with intricate patterns of director orientations.

A MAC protocol for UWB Very Low Power Mobile Ad-hoc Networks based on Dynamic Channel Coding with Interference Mitigation (2004)

We propose a MAC protocol for very low radiated power (1 microwatt) ultra-wide band (UWB) mobile ad-hoc networks. Unlike traditional approaches, our protocol fully utilizes the specific nature of the physical layer of UWB. This makes it possible to reach a reasonably high bit rate per source in spite of the low power, while being fully distributed. We use dynamic channel coding as an efficient way to adapt to varying channel conditions due to mobility and interference. Our design is based on existing theoretical findings that state that it is optimal to allow interfering sources to transmit simultaneously, as long as they are outside a well-defined exclusion region around a destination, and to adapt the channel code to this interference
Fluoro-alcohol materials with tailored interfacial properties for immersion lithography (2007)

Immersion lithography has placed a number of additional performance criteria on already stressed resist materials. Much work over the past few years has shown that controlling the water-resist interface is critical to enabling high scan rates (i.e. throughput) while minimizing film pulling and PAG extraction (i.e. defectivity). Protective topcoat polymers were developed to control the aforementioned interfacial properties and emerged as key enablers of 193 nm immersion lithography. Achieving the delicate balance between the low surface energies required for high water contact angles (generally achieved via the incorporation of fluorinated groups) and the base solubility required for topcoat removal is challenging. More recently, additional strategies using fluoropolymer materials to control the water-resist interface have been developed to afford topcoat-free resist systems. In our explorations of fluoroalcohol-based topcoat materials, we have discovered a number of structure-property relationships of which advantage can be taken to tailor the interfacial properties of these fluorinated materials. This paper will address the effect of structure on immersion specific properties such as water contact angle, aqueous base contact angle, and dissolution rate.
AUTOMATIC SEARCH AND CLASSIFICATION OF SOUND SOURCES IN LONG-TERM SURVEILLANCE RECORDINGS (2012)

The increasing availability of forensic audio surveillance recordings covering days or weeks of time makes human audition impractical. This paper describes the rationale and potential application of several techniques for high-speed automated search and classification of sound sources and sound events in long-term forensic audio recordings. Methods that can operate directly on perceptually compressed bitstreams without full decoding are of particular interest. Example applications include identification of aircraft overflights, the presence of human speech utterances, gunshot sounds, and other forensically relevant audio signals.
Singly resonant optical parametric oscillation in periodically poled lithium niobate waveguides (1997)

We report quasi-phase-matched singly resonant optical parametric oscillation in electric-field-poled lithium niobate waveguides. Parametric gains as high as 250%/W, an oscillation threshold of 1.6 W (peak), idler output powers of 220 mW, and a tuning range of 1180-2080 nm for pump wavelengths of 756-772 nm have been observed. Pump depletion is limited to 40% because of the multiple launched transverse modes at the pump wavelength. We predict that fully optimized waveguide singly resonant oscillators can have thresholds of ~100 mW, accessible to cw diode pumping.
High-Pressure Sonoelectrochemistry in Aqueous Solution: Soft Cavitation under CO2 (1998)

A novel high-pressure sonoelectrochemical cell has been developed in order to study the effect of pressure on cavitation and acoustic streaming in electrochemical processes. The reversible one electron reduction of a solution of Ru(NH3)63+ in aqueous 0.1 M KCl at a 25 μm diameter Pt microdisk electrode was studied under up to 60 bar pressure of argon and carbon dioxide and in the presence of ultrasound. The resulting cathodic current response was interpreted to be composed of a steady macroscopic streaming induced component and a transient spikelike component detected after the onset of the cavitation. The threshold for the cavitation process was strongly dependent on pressure and increased monotonically in the presence of argon. However, the threshold appeared at lower ultrasound power when pressurizing with carbon dioxide and even decreased at higher pressures (>40 bar) in the presence of CO2. The analysis of the observed phenomena is possible in terms of the mechanical pressure, the surface tension, and the formation of a liquid CO2 phase.

Nanotherapeutics for Nose-to-Brain Drug Delivery: An Approach to Bypass the Blood Brain Barrier (2021)

Treatment of neurodegenerative diseases or other central nervous system (CNS) disorders has always been a significant challenge. The nature of the blood-brain barrier (BBB) limits the penetration of therapeutic molecules to the brain after oral or parenteral administration, which, in combination with hepatic metabolism and drug elimination and inactivation during its journey in the systemic circulation, decreases the efficacy of the treatment, requires high drug doses and often induces adverse side effects. Nose-to-brain drug delivery allows the direct transport of therapeutic molecules by bypassing the BBB and increases drug concentration in the brain. The present review describes mechanisms of nose-to-brain drug delivery and discusses recent advances in this area with especial emphasis on nanotechnology-based approaches.

[Phosphate transform of composting with pre-mixing insoluble phosphate using high temperature dissolved phosphorus microbes inoculation]. (2008)

In order to enhance the available phosphorus (P) of compost production, the experimental design of composting included three treatments was conducted. The treatments were: Control (CK) with no dissolved phosphate microbes inoculation, no rock phosphate mixing; CP with no dissolved phosphate microbes inoculation, rock phosphate mixing; CMP with dissolved phosphate microbes inoculation, rock phosphate mixing. At different composting phases, the samples were taken for the determination of phosphorus forms. Compared to CK, organic P, dissolved P and rapidly available P of CP increase by 2 049.8, 264.2, 954.0 mg/kg at final stage of composting, respectively; while that of CMP increase by 4 188.6, 648.7, 3 576.4 mg/kg, respectively. The increase of organic P, dissolved P and rapidly available P in CMP is 2.04, 2.46, 3.75 times as that of CP, respectively. The results indicated dissolved phosphate microbes inoculation composting with pre-mixing rock phosphate would accelerate transform efficiency of insoluble phosphate, increase the available P of compost production.

Control system design for a robotic autoloader (1984)

Control system design for a robot operating in a constrained work volume is addressed. The controllers must be designed so that the resultant trajectories do not violate these boundary constraints. Furthermore, the trajectories must be near minimum time and have minimum fluctuation to satisfy the spatial constraints, as well as minimum overshoot for endpoint accuracy. The most stringent requirements are that the controllers must be implementable using state of the art computer components and they must have adequate robustness to allow for robot parameter variations and disturbances. To meet these requirements one is restricted to somewhat classical controllers such as PID, nonlinear feedback laws with integrators and for certain tasks, minimum time strategies are applicable. Thus, the purpose of this paper is to investigate and compare these strategies subject to the above constraints.
Using stability of interpretation as verification for low level processing: An example from egomotion and optic flow (2002)

A method is presented for validating low level optic flow computations in an image sequence by a simple analysis of the stability of the three-dimensional interpretation of the scene. Given computed optic flow and known egomotion, a viewer centered depth image is computed. By warping a finite history of previous depth images to the current viewer-centered system, the stability of the depth estimate at each point is analysed. Regions of low stability indicate image regions where the low level optic flow computation is unreliable. It is proposed that this approach is an example of performing verification mode vision, i.e., simple low-level computations are adequate when the interpretation provided is consistent with respect to the current scene interpretation. >
Preparation of Ceramic Toner by Suspension Polymerization (2012)

In ceramic decoration by xerography, once the toner particles have been deposited, the substrates need to be subjected to thermal treatment at temperatures above 600&#x2218;C to eliminate the organic constituents and enable the inorganic constituents to be integrated into the ceramic surface. The inorganic component includes a fraction that is able to modify the aesthetic appearance and a fraction that facilitates fusibility and integration into the substrate. At present, this type of toner is made by the pulverization method, with the presence of irregularly shaped particles and inorganic particles that are only partly coated by the polymeric matrix, which can lead to problems of particle flowability and electrical conductivity. This article describes a new method of ceramic toner preparation by suspension polymerization that avoids the above problems. The method allows a high inorganic component content in the toner composition to be reached, assuring good color saturation in decoration.
Reversible Photocycloadditions, a Powerful Tool for Tailoring (Nano)Materials (2011)

Abstract Molecularly designed materials are increasingly attracting attention not only because of the variety of their applications but also due to the challenging strategies necessary for their design and synthesis. Highly complex and functional (nano)materials are obtained by exploiting simple tools and concepts from different disciplines, introducing the desired properties into the final product. It is shown that by combining fundaments from organic chemistry, polymer and materials science, photoresponsive nanoparticles are easily generated, and how responsiveness is achieved by exploiting photocycloadditions, which are extremely selective, react in good yields without the formation of side products, proceed under benign conditions, and present the great advantage of being reversible.

Improving Confidentiality in Virtualized FPGAs (2018)

FPGAs are being deployed in modern datacenters to provide users with specialized accelerators that offer superior compute capability, increased energy efficiency, lower latency, and more programming flexibility than CPUs. However, FPGAs are not utilized as efficiently in datacenters: unlike CPUs, FPGAs in datacenters are currently not shared between users due to potential security risks. The higher flexibility that comes with FPGAs also gives more capabilities to malicious users. Several recent studies have demonstrated examples of FPGA user applications capable of remotely sniffing data from other applications running on the same FPGA. In this work, we look at various ways to ameliorate these threats by encrypting/decrypting the user application's data under different trust levels for current virtualized FPGAs. We also discuss the role of interconnect and discuss the potential of more efficient security features that can be implemented together with the interconnect if the FPGAs use a hard network on chip.
Dynamically Instrumenting the QEMU Emulator for Linux Process Trace Generation with the GDB Debugger (2014)

In software debugging, trace generation techniques are used to resolve highly complex bugs. However, the emulators increasingly used for embedded software development do not yet offer the types of trace generation infrastructure available in hardware. In this article, we make changes to the ARM ISA emulation of the QEMU emulator to allow for continuous instruction-level trace generation. Using a standard GDB client, tracepoints can be inserted to dynamically log registers and memory addresses without altering executing code. The ability to run trace experiments in five different modes allows the scope of trace generation to be narrowed as needed, down to the level of a single Linux process. Our scheme collects the execution traces of a Linux process on average between 9.6x--0.7x the speed of existing QEMU trace capabilities, with 96.7% less trace data volume. Compared to a software-instrumented tracing scheme, our method is both unobtrusive and performs on average between 3--4 orders of magnitude faster.
