Bandwidth Efficient Homomorphic Encrypted Matrix Vector Multiplication Accelerator on FPGA (2022)

Homomorphic Encryption (HE) is a promising solution to the increasing concerns of privacy in Machine Learning (ML) as it enables computations directly on encrypted data. However, it imposes significant overhead on the compute system and remains impractically slow. Prior works have proposed efficient FPGA implementations of basic HE primitives such as number theoretic transform (NTT), key switching, etc. Composing the primitives together to realize higher level ML computation is still a challenge due to the large data transfer overhead. In this work, we propose an efficient FPGA implementation of HE Matrix Vector Multiplication <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$(\mathbf{M}\times \mathbf{V})$</tex> , a key kernel in HE-based Machine Learning applications. By analyzing the data reuse characteristics and the encryption overhead of HE <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\mathbf{M}\times \mathbf{V}$</tex> , we show that simply using the principles of unencrypted <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\mathbf{M}\times \mathbf{V}$</tex> to design accelerators for HE <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\mathbf{M}\times \mathbf{V}$</tex> can lead to a significant amount of DRAM data transfers. We tackle the computation and data transfer challenges by proposing a bandwidth efficient dataflow that is specially optimized for HE <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\mathbf{M}\times \mathbf{V}$</tex> . We identify highly reused data entities in HE <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\mathbf{M}\times \mathbf{V}$</tex> and efficiently utilize the on-chip SRAM to reduce the DRAM data transfers. To speed up the computation of HE <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\mathbf{M}\times \mathbf{V}$</tex> , we exploit three types of parallelism: partial sum parallelism, residual polynomial parallelism and coefficient parallelism. Leveraging these innovations, we demonstrate the first FPGA accelerator for HE matrix vector multiplication. Evaluation on 7 HE <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\mathbf{M}\times \mathbf{V}$</tex> benchmarks shows that our FPGA accelerator is up to <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$3.8\times$</tex> (GeoMean <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$2.8\times$</tex> ) faster compared to the 64-thread CPU implementation.
Pre-distorted amplitude modulated (PDAM) chirps for transducer compensation in second and sub-harmonic imaging (2012)

A pre-distortion by amplitude modulate (PDAM) method is evaluated for use in linear frequency modulated (LFM) coded harmonic imaging. LFM coded signals are known to boost the SNR of the low amplitude harmonics, but due to the nature of harmonic imaging, are located at inefficient regions of the transducer’s bandwidth. As a consequence, the LFM signal is subjected to transducer-induced tapering which is particularly severe at the start or end of the signal. The motivation for this work is to investigate whether compensating for this tapering effect results in improved compression of the harmonic signal. PDAM signals are designed using an inverse filter method. Hydrophone measurements show successful transducer compensation of the fundamental signal. Fundamental and second harmonic images of a tissue mimicking phantom indicate minimal improvement when compared with non pre-distorted LFM signals (N-PDAM). A discussion is provided as to why this result can be attributed to the use of a sub-optimal compression filter.
PM-Assisted Reluctance Synchronous Motor/Generator (PM-RSM) for Mild Hybrid Vehicles: Electromagnetic Design (2004)

This paper introduces the conceptual design and finite-element method analysis of a permanent-magnet-assisted reluctance synchronous motor/generator for mild hybrid vehicles where a large constant power speed range (6:1) is required and machine volume, converter peak kVA, and battery size are the main constraints. Careful flux-barrier and permanent-magnet sizing, high magnetic saturation, and current density are the main requirements for maximum torque production with constraint volume. A specific tangential force density of 4.33 N/cm/sup 2/ is obtained. Rated (continuous) power-battery limited is 2.5 kW at 42 V dc, from 1000 to 6000 r/min. The peak torque of 140 N/spl middot/m is obtained at 202 A (rms/phase) and can be secured up to 500 r/min. Peak power is still 7.85 kW at 6000 r/min at 42 V dc with an efficiency of 90%. Preliminary results on a prototype are also available.

Effects of zero-mass 'synthetic' jets on the aerodynamics of the NACA-0012 airfoil (1997)

A numerical study was conducted to investigate the effect of an array of zero-mass synthetic jets on the aerodynamic characteristics of the NACA-0012 airfoil. Flowfield predictions were made using a modified version of the NASA Ames ARC2D unsteady, two-dimensional, compressible Navier-Stokes flow solver. An unsteady surface transpiration boundary condition was enforced over a user-specified portion of the airfoil's upper or lower surface to emulate the time variation of the mass flux out from and into the airfoil's surface. Here, a sinusoidal function which describes the approximate time behavior of the mass flux across the airfoil's surface was used. Our numerical results have indicated that zero-mass jets can, with the careful selection of their peak amplitude and frequency, enhance the lift characteristics of airfoils (helicopter rotor blades, wings, etc.). Effects of the jet peak suction and blowing velocities, oscillation frequency and, jet placement on the time histories of the sectional lift, drag and moment are presented for two angles of attack and one free stream Mach number. Flowfield results which provide more insight into the mechanics of the interaction between the array of jets and the developing boundary layer over the airfoil are presented.
Real-time near-field acoustic holography for continuously visualizing nonstationary acoustic fields (2010)

Near-field acoustic holography (NAH) is an effective tool for visualizing acoustic sources from pressure measurements made in the near-field of sources using a microphone array. The method involving the Fourier transform and some processing in the frequency-wavenumber domain is suitable for the study of stationary acoustic sources, providing an image of the spatial acoustic field for one frequency. When the behavior of acoustic sources fluctuates in time, NAH may not be used. Unlike time domain holography or transient method, the method proposed in the paper needs no transformation in the frequency domain or any assumption about local stationary properties. It is based on a time formulation of forward sound prediction or backward sound radiation in the time-wavenumber domain. The propagation is described by an analytic impulse response used to define a digital filter. The implementation of one filter in forward propagation and its inverse to recover the acoustic field on the source plane implies by simulations that real-time NAH is viable. Since a numerical filter is used rather than a Fourier transform of the time-signal, the emission on a point of the source may be rebuilt continuously and used for other post-processing applications.

Neonatal Marfan Syndrome: Report of a Case with an Inherited Splicing Mutation outside the Neonatal Domain (2015)

We report a child and her mother affected by Marfan syndrome. The child presented with a phenotype of neonatal Marfan syndrome, revealed by acute and refractory heart failure, finally leading to death within the first 4 months of life. Her mother had a common clinical presentation. Genetic analysis revealed an inherited FBN1 mutation. This intronic mutation (c.6163+3_6163+6del), undescribed to date, leads to exon 49 skipping, corresponding to in-frame deletion of 42 amino acids (p.Ile2014_Asp2055del). FBN1 next-generation sequencing did not show any argument for mosaicism. Association in the same family of severe neonatal and classical Marfan syndrome illustrates the intrafamilial phenotype variability.
Clinical and Pathological Significance of Mesangial C1q Deposition in Kidney Transplant Recipients with Recurrent IgA Nephropathy and Patients with Native IgA Nephropathy (2023)

Mesangial C1q deposition was more frequent in KTRs with recurrent IgAN than in patients with native IgAN, but we found no difference in kidney outcomes with respect to mesangial C1q deposition. Further large-scale investigations of the importance of mesangial C1q deposition are needed in both KTRs with recurrent IgAN and patients with native IgAN.

Exploitation of Transparent Conductive Oxides in the Implementation of a Window-Integrated Wireless Sensor Node (2018)

Exploitation of transparent conductive oxides (TCOs) to implement an energy-autonomous sensor node for a wireless sensor network is studied and a practical solution presented. In the practical implementations, flexible and rigid substrates, i.e., polyimide and glass, are coated with TCO, namely, aluminum-doped zinc oxide (AZO). AZO-coated flexible substrates are used to form thermoelectric generators (TEGs) that produce electricity for the sensor electronics of the node from thermal gradients on a window. As the second solution to utilize AZO, its conductive properties are exploited to implement transparent antennas for the sensor node. Antennas for a UHF RFID transponder and the Bluetooth radio of the node are implemented. A prototype of a flexible transparent TEG, with the area of 67 cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> when folded, was measured to produce power of 1.6 μW with a temperature difference of 43 K. A radiation efficiency of -9.1 dB was measured for the transparent RFID antenna prototype with the center frequency of 900 MHz. Radiation efficiencies between -3.8 and -0.4 dB, depending on the substrate, were obtained for the 2.45 GHz Bluetooth antenna.
Predictive Control of a Robotic Grinding System (1992)

This paper describes a modified predictive controller that has been interfaced with the robotic weld bead grinding system currently under development at The Charles Stark Draper Laboratory. The objective of the predictive control in the grinding system is to invert the previously modeled grinding dynamics. This is accomplished via a link between the controller and a grinding simulator that has been developed, based on an exchange of geometric and force data used by both algorithms. The interface utilizes vision data obtained from previous grinding passes to generate a force trajectory used by the robot on the subsequent pass. This trajectory is precomputed by the predictive controller to yield a specific weld bead shape. Due to system limitations, measurement noise, and modelling errors, the beads are not ground perfectly flat. However, their cross sectional area (or height) variations are reduced significantly. Thus, the bead is flattened although not completely.
Investigations of Potential Induced Degradation of Silicon Photovoltaic Modules (2011)

In the last few years, it became apparent that system voltage can lead to substantial long-term potential induced degradation (PID) of photovoltaic modules via shunting of the incorporated wafer based screen-printed solar cells. The leakage current from the module frames to the cells through the encapsulating material is supposed to cause this effect. Until now the detailed mechanism of shunting is not known although it was speculated that metal ions originating from the soda-lime glass might be responsible. In this study, experimental evidence is presented showing that PID can also be caused by other ions usually not present in photovoltaic modules indicating that the chemical nature of the ions is not relevant for PID. The conditions under which PID occurs in the field are substantiated from the analysis of leakage current data measured outdoor. Starting from these conditions, different options for accelerating a laboratory test for PID are discussed and tested experimentally.
Comparative Analysis of Sliding Mode Controller and Hysteresis Controller for Active Power Filtering in a Grid connected PV System (2019)

This paper presents a comparative assessment of two controllers, namely sliding mode controller and hysteresis controller for active power filtering of a grid integrated Photovoltaic (PV) system. These control algorithms were employed in Voltage Source Inverter (VSI) for active power filtering as well as for converting the dc voltage from PV array to 3-phase ac voltage. For superior tracking efficiency a modified Incremental Conductance Maximum Power Point Tracking (ICMPPT) algorithm is employed to extract maximum power from PV panels. A PI controller is used for regulation of dc link capacitor voltage. Instantaneous power theory based reference current generation is used for the active power filtering. Both sliding mode control algorithm and hysteresis control algorithm are designed for tracking the reference inverter current in order to elimination the grid current harmonics. The steady state and transient performances of the two controllers i. e. sliding mode controller and hysteresis controller are compared. These two control schemes are implemented on a grid connected PV system firstly using MATLAB/Simulink and then on an experimental setup developed in the laboratory. From the obtained simulation and experimental results, it is found that sliding mode controller exhibits superior performance such as better transient and steady state behavior under parameter uncertainties as compared to the hysteresis controller.

These studies confirm that amino acid clearances are relatively high during CAVHD and daily losses should therefore be considered.
Abstract PR011: TXNRD1 drives innate immune response in senescent cells to promote tumor immune surveillance and age-associated inflammation (2023)

Abstract Cellular senescence regulates cancer and tissue aging in part through the secretion of proinflammatory factors known as the senescence-associated secretory phenotype (SASP). For example, sterile inflammation or ‘inflammaging’ is a hallmark of tissue aging. Thioredoxin reductase 1 (TXNRD1) genetic variability is associated with aging and is often upregulated in human cancers. TXNRD1’s role in regulating tissue aging and cancer has been attributed to its enzymatic role in regulating cellular redox. Here we show that TXNRD1 drives the SASP and inflammation through the cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) innate immune response pathway independently of its enzymatic activity. TXNRD1 localizes to cytoplasmic chromatin fragments (CCF) and interacts with cGAS in a senescence status dependent manner, which is required for the SASP. Biochemically, TXNRD1 enhances the enzymatic activity of cGAS. TXNRD1 is required for both the tumor-promoting and immune-surveillance functions of senescent cells, which are mediated by the SASP in vivo in mouse tumor models. Treatment of aged mice with a TXNRD1 inhibitor that disrupts its interaction with cGAS, but not an inhibitor of its enzymatic activity alone, downregulated inflammaging in several tissues. In summary, our results report TXNRD1 promotes inflammation via activating the innate immune response in a manner depending on its interaction with cGAS but not its enzymatic activity. Our findings have important implications for both tissue aging and cancer. Citation Format: Xue Hao, Bo Zhao, Martina Towers, Liping Liao, Hsin Yao Tang, Aaron Havas, Andrew V.
