New Security Challenges on Machine Learning Inference Engine: Chip Cloning and Model Reverse Engineering (2020)

Machine learning inference engine is of great interest to smart edge computing. Compute-in-memory (CIM) architecture has shown significant improvements in throughput and energy efficiency for hardware acceleration. Emerging non-volatile memory technologies offer great potential for instant on and off by dynamic power gating. Inference engine is typically pre-trained by the cloud and then being deployed to the filed. There are new attack models on chip cloning and neural network model reverse engineering. In this paper, we propose countermeasures to the weight cloning and input-output pair attacks. The first strategy is the weight fine-tune to compensate the analog-to-digital converter (ADC) offset for a specific chip instance while inducing significant accuracy drop for cloned chip instances. The second strategy is the weight shuffle and fake rows insertion to allow accurate propagation of the activations of the neural network only with a key.
Discrimination of thermophilic and mesophilic proteins (2009)

There has been considerable interest in the physical basis for the increased thermostability of thermophilic proteins with respect to their mesophilic counterparts since the discovery of highly thermo-tolerant organisms. We have systematically studied a large set of protein structures in order to find those properties with the most power to discriminate mesophilic proteins from their thermophilic orthologs. Most of the structure-based descriptors used in our discrimination and classification experiments were derived from the Delaunay tessellations of the protein structures.
Controlling electromagnetic surface waves with scalar and tensor impedance surfaces (2013)

The propagation characteristics of electromagnetic waves on various isotropic (scalar) impedance surfaces have been studied for some time, in order to control surface waves and leaky-wave radiation. One and two dimensional periodic impedance surfaces as well as tensor impedance surfaces, have been explored for enhanced control of wave guidance. The desire to integrate antennas and electromagnetic devices onto the surfaces of vehicles and other platforms has driven recent interest in both scalar and tensor impedance surfaces. Great strides have been made in the design of devices based on impedance surfaces. To date, these devices are designed by first determining the surface impedance variation necessary to yield the desired performance. The surfaces are then implemented as printed-circuit board (PCB) structures consisting of a patterned metallic cladding over a grounded dielectric substrate. In other words, these two-layer structures are modeled with an idealized tensor impedance boundary condition. In this work, we aim to capture the propagation characteristics of PCB-based tensor impedance surfaces more accurately by modeling them as an impedance sheet over a grounded dielectric substrate. The impedance sheet represents the patterned metallic cladding of the PCB tensor impedance surface. Dispersion equations for scalar and tensor PCB versions are found. In addition, an extraction method is presented that allows the impedance sheet to be found using only two full-wave simulations. Using the dispersion equation and the extraction method together, the dispersion properties of the printed-circuit impedance surface can be predicted. A method for designing transformation electromagnetics devices using tensor impedance surfaces is also presented. Further, a printed leaky-wave antenna based on a sinusoidally modulated scalar impedance surface is presented.
Differential in vivo activation of the class II and class III snRNA genes by the POU-specific domain of Oct-1 (1997)

Many snRNA genes contain binding sites for the ubiquitous transcription factor Oct-1. In vitro studies have shown that this factor potentiates binding of an essential transcription factor (PTF) to the proximal sequence element (PSE) of snRNA genes, and activates transcription. Using Gal4 fusion proteins, I show here that the POU-specific region of the DNA-binding domain of Oct-1 is sufficient both to potentiate PTF binding in vitro and to transactivate pol II- and pol III-dependent snRNA genes in vivo . A single amino acid change in this domain abrogates both activation and interaction with PTF. The N- and C-terminal regions of Oct-1 also activate transcription of both classes of snRNA genes. Wild-type levels of Pol II-dependent U2 expression require all activation domains, whereas efficient activation of the pol III-dependent 7SK and U6 genes is effected by the POU-specific domain alone. These results indicate that contacts between PTF and amino acids in the POU-specific domain of Oct-1 are critical for efficient transactivation of snRNA genes in vivo. The POU-specific domain of Oct-2A also activates these genes, but the N- and C-terminal domains are relatively inactive.
Interaction of methotrexate, folates, and pyridine nucleotides with dihydrofolate reductase: calorimetric and spectroscopic binding studies. (1978)

The thermodynamic parameters, deltaG, deltaH, and deltaS characterizing the tight binding of methotrexate, folates, and pyridine nucleotides to chicken liver dihydrofolate reductase (5,6,7,8-tetrahydrofolate: NADP+ oxidoreductase, EC 1.5.1.3) have been determined from calorimetric and fluorescence measurements. At 25 degrees the binding of NADPH and NADP+ is characterized by small negative enthalpies and large positive entropies whereas the binding of the folates and methotrexate is accompanied by large negative enthalpies and small negative entropies. In addition, the enthalpy of methotrexate-enzyme interaction demonstrates a proton transfer associated with binding; this is not the case with folate and dihydrofolate, thus confirming the conclusions drawn from the observed difference spectra characteristic of the interaction of methotrexate and substrates with the enzyme. The implications of these results are discussed in terms of the nature of the binding process, conformational changes in the enzyme, and the nature of the active site region.
Evolution of molecular weight distributions in the catalytic chain transfer polymerization of methyl methacrylate up to high monomer conversions (2000)

The evolution of molecular weight distributions (MWDs) with monomer conversion in the catalytic chain transfer (CCT) polymerization of methyl methacrylate at 60 °C is investigated by simulation (via the program package PREDICI®) and experiment. A Co(III)-based complex is used as the precursor for the CCT agent, which is formed in situ by initiator-derived (2,2′-azobisisobutyronitrile) radicals to yield the catalytically active Co(II) species. The small shifts seen in the MWD toward lower molecular weights with increasing monomer conversion are shown to be of the same order of magnitude as the associated changes in the MWD in non-CCT controlled free-radical polymerization, indicating that no significant change in the MWD with monomer conversion is associated with the CCT process. These results are compared to the evolution of MWDs in conventional chain transfer polymerizations with thiols as transfer agents. A clear shift toward higher molecular weights is seen with increasing monomer conversion, indicating disparate rates of thiol and monomer consumption. © 2000 John Wiley & Sons, Inc.

Homocysteine as a Risk Factor for Atherosclerosis (2000)

Studies demonstrate a positive correlation between hyperhomocysteinemia and atherosclerosis. The treatment of choice for hyperhomocysteinemia is folic acid. Although the optimal dose is not known, 650 microg/d is the minimum effective dose. To date, no studies have assessed the effects on morbidity and mortality when treating high homocysteine concentrations in atherosclerotic patients.

A Model for Mechanical Seals with Regular Microsurface Structure (1996)

Abstract A mathematical model is developed to allow performance prediction of all-liquid noncontacting mechanical seals with regular microsurface structure in the form of hemispherical pores. Seal performance such as the equilibrium face separation, friction torque and leakage across the seal are calculated and presented for a range of sealed pressure, pore size and pore ratio of ring surface area. An optimum pore size is found that depends on the other variables and corresponds to maximum axial stiffness and minimum friction torque. Also, a critical pore size is found above which seal failure is possible. Presented as a Society of Tribologists and Lubrication Engineers paper at the STLE/ASME Tribology Conference in Kisslmmee, Florida, October 8–11, 1995 KEY WORDS: Mechanical SealsSeals Notes Presented as a Society of Tribologists and Lubrication Engineers paper at the STLE/ASME Tribology Conference in Kisslmmee, Florida, October 8–11, 1995

Influence of Bath Temperature, Deposition Time and S/Cd Ratio on the Structure, Surface Morphology, Chemical Composition and Optical Properties of CdS Thin Films Elaborated by Chemical Bath Deposition (2011)

Cadmium sulphide (CdS) thin films were deposited on glass substrates by the chemical bath deposition (CBD) method, using anhydrous cadmium chloride (CdCl2) and thiourea (CS(NH2)2) as sources of cadmium and sulphur ions respectively. The influence of bath temperature (Tb), deposition time (td) aSnd [S]/[Cd] ratio in the solution on the structural, morphological, chemical composition and optical properties of these films were investigated. XRD studies revealed that all the deposited films were polycrystalline with hexagonal structure and exhibited (002) preferential orientation. The films deposited under optimum conditions (Tb = 75?C, td = 60 min and [S]/[Cd] ratio = 2.5) were relatively well crystallized. These films showed large final thickness and their surface morphologies were composed of small grains with an approximate size of 20 to 30 nm and grains grouped together to form large clusters. EDAX analysis revealed that these films were nonstoichiometric with a slight sulphur deficiency. These films exhibited also a transmittance value about 80% in the visible and infra red range.
Applications and equivalent models for coupled inductor parallel interleaved converters (2004)

Parallel interleaved converters are finding more applications everyday, for example they are frequently used for VRMs on PC main boards mainly to obtain better transient response. Parallel interleaved converters can have their inductances uncoupled, directly coupled or inversely coupled, all of which have different applications with associated advantages and disadvantages. Coupled systems offer more control over converter features, such as ripple currents, inductance volume and transient response. To be able to gain an intuitive understanding of which type of parallel interleaved converter, what amount of coupling, what number of levels and how much inductance should be used for different applications a simple equivalent model is needed. As all phases of an interleaved converter are supposed to be identical, the equivalent model is nothing more than a separate inductance which is common to all phases. Without utilising this simplification the design of a coupled system is quite daunting. Being able to design a coupled system involves solving and understanding the RMS currents of the input, individual phase (or cell) and output. A procedure using this equivalent model and a small amount of modulo arithmetic is detailed.
Study of miscibility, crystallization, mechanical properties, and thermal stability of blends of poly(3‐hydroxybutyrate) and poly(3‐hydroxybutyrate‐<i>co</i>‐4‐hydroxybutyrate) (2007)

Abstract Natural amorphous polymer poly(3‐hydroxybutyrate‐ co ‐4‐hydroxybutyrate) (P3HB4HB) containing 41 mol % of 4HB was blended with poly(3‐hydroxybutyrate) (PHB) with an aim to improve the properties of PHB. The influence of P3HB4HB contents on thermal and mechanical properties of the blends was evaluated with differential scanning calorimetry (DSC), Fourier transform infrared (FTIR) spectroscopy, stress–strain measurement and thermo gravimetric analyzer. Miscibility of PHB/P3HB4HB blends was mainly decided by the contents of P3HB4HB. When P3HB4HB exceeded 50 wt %, the two polymer phases separated and showed immiscibility. The addition of P3HB4HB did not alter the crystallinity of PHB, yet it diluted the PHB crystalline phase as revealed by DSC studies. DSC and FTIR results showed that the overall crystallinity of the blends decreased remarkably with increasing of P3HB4HB contents. Decreased glass transition temperature and crystallinity imparted desired flexibility for the blends. The ductility of the blends increased progressively with increasing of P3HB4HB content. Thus, the PHB mechanical properties can be modulated by changing the blend composition. P3HB4HB did not significantly improve the thermal stability of PHB, yet it is possible to melt process PHB without much molecular weights loss via blending it with suitable amounts of P3HB4HB. © 2007 Wiley Periodicals, Inc.

Bridging the Gap between Flexibility and Rigidity: Unifying Relationships with a Hybrid Link Architecture (2005)

Current knowledge systems lack an effective architecture to bridge the well-acknowledged gap between flexibility and rigidity - usersâ preference of flexible expression and machineâs need for rigorous representation. This paper focuses on finding an adequate set of relationship types (or link types) and map flexible expressions from users to link types in propositional knowledge systems, in which knowledge elements are stored as âconcept-relationship-conceptâ triplets. We call our approach âhybrid link architectureâ. This architecture has two levels of presentations, an open link name layer and a closed link type layer. Between these two layers is a matching mechanism based on a psycholinguistic thesaurus to map names to types. The link types are derived by synthesizing literature of knowledge organization, semantic network, and educational taxonomies. A two-stage evaluation is conducted based on 39,706 triplets. The evaluation shows that the matching mechanism is accurate and the proposed link types are mutually exclusive and cover most link names in our dataset.
Reconfigurable mobile stream processor for ray tracing (2010)

This paper presents a reconfigurable mobile stream processor for ray tracing. The processor is implemented with 16mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> area in 0.13µm CMOS technology. The processor adopts a single instruction, multiple thread (SIMT) architecture in order to exploits instruction-level and thread-level parallelism. The SIMT architecture consists of 12 stream processors (SPs). A low hardware utilization caused by a branch divergence in SIMT architecture is addressed by reconfiguring the SPs between scalar SIMT and vector SIMT with negligible hardware overheads. A slim special function unit (SFU) with a table loader reduces the SFU area and look-up table access counts. Reusing previous result for a ray generator reduces its operations by up to 71.9%. The proposed processor achieves a peak performance of 673K rays per second while consuming 156mW.
Dynamic path planning algorithm for autonomous vehicles in cluttered environments (2016)

In this paper, a method of dynamic path planning algorithm for autonomous vehicles in cluttered environments is presented. The proposed method is based on the D* Lite algorithm with a smoothing method and local optimisation to enhance its performance in cluttered environments. The Lowess smoothing method has useful properties for the path planning problem especially in complex environments which involve lots of corners or direction changes required to avoid dynamic obstacles. Cubic Hermite spline interpolation is used to describe curvature continuous trajectories for autonomous vehicles. Knowing the start and goal position, a continuous smooth trajectory can be decided. Results of proposed method are shown in simulations and experiments. Trajectories are demonstrated in various environments with and without additional obstacles. Quantitative results are shown and analysed to validate the proposed method.
Fe3O4 Nanoparticles coated with homopolymers of glycerol mono(meth)acrylate and their block copolymers (2005)

Highly stable aqueous magnetic fluids were prepared by coating Fe3O4 nanoparticles with poly(glycerol monoacrylate), poly(glycerol monomethacrylate), or diblock copolymers, poly(acrylic acid)-b-poly(glycerol monoacrylate), poly[(N,N-dimethylamino)ethyl methacrylate]-b-poly(glycerol monomethacrylate) or poly(ethylene glycol) monomethyl ether-b-poly(glycerol monoacrylate). These homopolymers and block copolymers were synthesized by atom transfer radical polymerization. These dispersions were stable in 10% NaCl, 10% CaCl2, or in wide pH ranges. In these magnetic fluids, poly(glycerol monoacrylate) or poly(glycerol monomethacrylate) were chemisorbed onto the Fe3O4 nanoparticle surface through their 1,2-diol groups by forming five-membered chelate rings with the Fe atoms, while the other blocks in the cases of the block copolymers as the stabilizers extended into the water matrix. Thus the nanoparticles prepared with these three block copolymers mentioned above respectively contain negatively charged, positively charged or uncharged and biocompatible surfaces under physiological conditions. This procedure provided a good choice for preparing stable magnetic fluids with tailored surfaces and/or tailored functional groups on the surfaces of the magnetic nanoparticles.
Optimal power allocation and network beamforming for OFDM-based relay networks (2014)

We herein consider the problem of optimal power allocation in an OFDM two-way relay network with multiple relays. Assuming two-way relaying is performed using analog network coding, we obtain the optimal power allocation across subcarriers and among a relay and two communicating nodes by minimizing the total power consumption in the network subject to two separate rate constraints for each transceiver. We then present an algorithm to solve the proposed optimization problem. Our simulation result shows that the proposed algorithm significantly outperform an equal power allocation scheme, where all subcarriers at all nodes receive the same levels of power and the total power is equal to that consumed in our proposed solution.

Fast handover algorithm for hierarchical mobile IPv6 macro-mobility management (2004)

Mobile IPv6 (MlPv6) has some limitations due to long delays and signaling load during handover operation. Hierarchical mobile IPv6 (HMIPv6) is the extension of MIPv6 that is designed to reduce the signaling load and to improve handover speed of MIPv6 by splitting the mobility management into macro and micro mobility management schemes. However HMIPv6 only improves micro mobility problem where the significant delay still occurs in the macro mobility management because the handover algorithm is similar with the MIPv6 environment. This paper proposes a new fast handover algorithm that overcomes the limitations in mobile MIPv6 and its extension HMIPv6. Our design objective is to re-establish the communication traffic flow quickly and to minimize the service disruption delay that occurs during handover process in a macro mobility environment. This handover algorithm is based on the modification of the HMIPv6 protocol using the multicast technique concept. This algorithm will enable the mobile node to receive packet faster than HMIPv6 protocol during handover, seamlessly and transparently.
