Noise Isolation in Mixed-Signal Systems Using Alternating Impedance Electromagnetic Bandgap (AI-EBG) Structure-Based Power Distribution Network (PDN) (2009)

<para xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> This paper presents efficient noise isolation and suppression method in mixed-signal systems using alternating impedance electromagnetic bandgap (AI-EBG) structure-based power distribution network (PDN). Currently, split planes are used for isolation in mixed-signal systems for isolating sensitive RF/analog circuits from noisy digital circuits. However, split planes show good isolation only at low frequencies due to electromagnetic coupling through the gap. The AI-EBG structure-based PDN presented in this paper provides excellent isolation (<formula formulatype="inline"><tex Notation="TeX">$-80~{\hbox {dB}} \! \sim \! -100~{\hbox {dB}}$</tex></formula>) in the frequency range of interest by suppressing almost all possible electromagnetic modes. The AI-EBG structure has been integrated into a mixed-signal test vehicle to demonstrate the isolation level achievable. The ability of the AI-EBG structure to suppress switching noise has been quantified in this paper. The AI-EBG structure provided greater than 100 dB of isolation in passive <formula formulatype="inline"><tex Notation="TeX">${ S}$</tex></formula>-parameter measurement and suppressed in-band noise down to <formula formulatype="inline"><tex Notation="TeX">$-88~{\hbox {dBm}}$</tex> </formula> of isolation in a functional test. </para>
Coherent backscattering spectroscopy: a new technique for tissue diagnosis (2005)

Coherent backscattering (CBS) is a photon weak-localization phenomenon that gives rise to an enhanced backscattering of light by random media. This effect has been previously investigated using coherent light sources. Here we show that CBS can be observed using broadband low-coherence light. We demonstrate, for the first time to the best of our knowledge, that low-coherence detection substantially simplifies CBS measurements in biological tissue and enables depth-resolved spectroscopic analysis of CBS. CBS spectroscopy may find important applications in probing random media such as biological tissues where depth-selective measurements are crucial.
Secondary metabolic gene cluster silencing in <i>Aspergillus nidulans</i> (2006)

In contrast to most primary metabolism genes, the genes involved in secondary metabolism and certain nutrient utilization pathways are clustered in fungi. Recently a nuclear protein, LaeA, was found to be required for the transcription of several secondary metabolite gene clusters in Aspergillus nidulans. Here we show that LaeA regulation does not extend to nutrient utilization or the spoC1 sporulation clusters. One of the secondary metabolite clusters regulated by LaeA contains the positive regulatory (i.e. aflR) and biosynthetic genes required for biosynthesis of sterigmatocystin (ST), a carcinogenic toxin. Analysis of ST gene cluster expression indicates LaeA regulation of the cluster is location specific as transcription of genes bordering the ST cluster are unaffected in a DeltalaeA mutant and placement of a primary metabolic gene, argB, in the ST cluster resulted in argB silencing in the DeltalaeA background. ST cluster gene expression was remediated when an additional copy of aflR was placed outside of the cluster but not when placed in the cluster. Site-specific mutation of an s-adenosyl methionine (AdoMet) binding site in LaeA generated a DeltalaeA phenotype suggesting the protein to be a methyltransferase.
Laser-based intense hard x-ray source for mammography (2003)

Characteristic Kα emissions from Mo, Ag and La targets irradiated by 60 fs, 600 mJ, 10 Hz Ti: Sapphire laser pulse at 10<sup>17</sup> W/cm<sup>2</sup> - 10<sup>19</sup> W/cm<sup>2</sup> can be potentially used in x-ray mammography. We have investigated x-ray spectra created by this novel x-ray source in this context. All the obtained spectra exhibited a dominating narrow emission lines with only a small portion of x-ray emission in Bremsstrahlung. Such spectra might be very usful in mammography and might improve contrast and dose utilizaion, as compared to a conventional mammographic x-ray tube. The effective focal spot size was of the order of 50 μm, i.e. significantly smaller than in conventional mammography. In contradiction to conventional mammography the effective x-ray focal spot size and the effective dose remained constant across the field of view. Kα conversion efficiency, from laser light to x-rays, was optimized and values as high as 2 x 10<sup>-5</sup> have been obtained.
Application-Transparent Near-Memory Processing Architecture with Memory Channel Network (2018)

The physical memory capacity of servers is expected to increase drastically with deployment of the forthcoming non-volatile memory technologies. This is a welcomed improvement for emerging data-intensive applications. For such servers to be cost-effective, nonetheless, we must cost-effectively increase compute throughput and memory bandwidth commensurate with the increase in memory capacity without compromising application readiness. Tackling this challenge, we present Memory Channel Network (MCN) architecture in this paper. Specifically, first, we propose an MCN DIMM, an extension of a buffered DIMM where a small but capable processor called MCN processor is integrated with a buffer device on the DIMM for near-memory processing. Second, we implement device drivers to give the host and MCN processors in a server an illusion that they are independent heterogeneous nodes connected through an Ethernet link. These allow the host and MCN processors in a server to run a given data-intensive application together based on popular distributed computing frameworks such as MPI and Spark without any change in the host processor hardware and its application software, while offering the benefits of high-bandwidth and low-latency communications between the host and the MCN processors over memory channels. As such, MCN can serve as an application-transparent framework which can seamlessly unify near-memory processing within a server and distributed computing across such servers for data-intensive applications. Our simulation running the full software stack shows that a server with 8 MCN DIMMs offers 4.56X higher throughput and consume 47.5% less energy than a cluster with 9 conventional nodes connected through Ethernet links, as it facilitates up to 8.17X higher aggregate DRAM bandwidth utilization. Lastly, we demonstrate the feasibility of MCN with an IBM POWER8 system and an experimental buffered DIMM.

A novel pharmacological modulator abrogates physiological mitochondrial fission though specifically inhibiting the Mff‐Drp1 protein‐protein interaction (2018)

Within a single mammalian cell, thousands of mitochondria form a dynamic network. The morphological state of this network is tightly linked to its function. Mitochondrial fission and fusion are at the core of mitochondrial dynamics. Cellular homeostasis depends on maintaining a balance between fission and fusion. An imbalance between these two processes is a hallmark of numerous pathologies. For example, excessive fission is found in cancers, cardiovascular disorders, and neurodegeneration. While mitochondrial fission poses as an attractive therapeutic target for these disorders, better tools are needed to differentiate physiological fission from excessive pathological fragmentation. The main regulator of fission is the cytosolic dynamin‐related protein 1 (Drp1), a large GTPase that uses mechanical force to constrict the mitochondrial membrane. Four identified adaptor proteins mediate Drp1 recruitment to the mitochondrial outer membrane, yet the function of Drp1 binding to each adaptor is unknown. We hypothesized that one adaptor, Mff, is primarily responsible for physiological fission. Therefore, a specific Mff‐Drp1 protein‐protein interaction inhibitor would differentiate physiological from pathological fission. Using a rational design approach, we identified a small peptide that specifically inhibits Drp1's interaction with Mff, but not with any of the other outer‐membrane adaptors: P259. Contrary to a Drp1/Fis1 inhibitor, treatment with P259 disrupted mitochondrial network morphology and function under basal conditions. Furthermore, inhibition of Mff‐specific Drp1 recruitment to the mitochondria halted mitochondrial motility, elucidating the mechanistic link between mitochondrial fission and transport. Mitochondrial motility is especially relevant in cell types with complex morphologies such as neurons. We therefore studied the effect of P259 in brains. In WT mouse brains, P259 limited mitochondrial recruitment of Drp1, resulting in a 30% decrease in ATP production and enlargement of striatal mitochondria by electron microscopy. Furthermore, treatment with P259 reduced the lifespan of R6/2 Huntington's Disease model mice and caused behavioral abnormalities in WT mice. Cumulatively, these results suggest that Mff orchestrates physiological recruitment of Drp1 to the mitochondrial membrane thereby maintaining mitochondrial network homeostasis through facilitating fission and motility. Results from this study suggest that Drp1's pathological or physiological roles are mediated through its specific interaction with adaptors on the mitochondrial outer membrane.

Magnetic resonance imaging compatible neonate incubator (2002)

Abstract An incubator for magnetic resonance imaging (MRI) of premature and full‐term infants was designed and constructed. The device is an extensively modified MRI system table that has a permanently attached incubator housing, self‐contained power supply, and full patient monitoring capability. A custom eight‐element birdcage coil within the incubator slides over the infant and provides high sensitivity for MRI. The incubator provides all the temperature control and patient monitoring found in conventional neonatal intensive care incubators, but in an MRI‐compatible fashion. The table can operate for at least three hours on a single battery charge. It is believed that this table design will enable routine MRI scanning of newborn infants requiring extensive monitoring of vital signs and/or temperature regulation. © 2002 Wiley Periodicals, Inc.

A memory efficient realization of cyclic convolution and its application to discrete cosine transform (2003)

This paper presents a memory efficient design for realizing the cyclic convolution and its application to the discrete cosine transform (DCT). We adopt the method of distributed arithmetic computation, and exploit the symmetry property of DCT coefficients to merge the elements in the matrix of the DCT kernel and then separate the kernel to be two perfect cyclic forms to facilitate an efficient realization of 1-D N-point DCT using (N-1)/2 adders or subtractors, one small ROM module, a barrel shifter, and N-1/2+1 accumulators. The comparison results with the existing designs show that the proposed design can reduce delay-area product significantly.
2-(Aminomethyl)pyridine−Phosphine Ruthenium(II) Complexes:  Novel Highly Active Transfer Hydrogenation Catalysts (2005)

The complexes trans,cis-RuCl2(PPh3)2(ampy) (1) and trans-RuCl2[Ph2P(CH2)4PPh2](ampy) (2) have been prepared in high yield by reaction of RuCl2(PPh3)3 and RuCl2(PPh3)[Ph2P(CH2)4PPh2] with 2-(aminomethyl)pyridine (ampy) at room temperature by PPh3 displacement. Heating compound 1 in refluxing toluene leads to the isomer cis,cis-RuCl2(PPh3)2(ampy) (3), which has been proven to be a good precursor for the preparation of the complexes cis-RuCl2(PP)(ampy) [PP = (S,S)-Chiraphos, 4; Ph2P(CH2)3PPh2, 5; (S,S)-Skewphos, 6; Ph2P(CH2)4PPh2, 7; (R,R)-Diop, 8] by displacement of two PPh3 with the appropriate diphosphine. The derivatives cis-RuCl2(PP)(ampy) [PP = (R,S)-Josiphos, 9; (R,S)-tBu-Josiphos, 10] have been synthesized from RuCl2(PPh3)3 and PP followed by addition of ampy. The chiral complexes 4, 6, 8, 9, and 10 are formed stereoselectively, as inferred by NMR data in solution. For the derivatives 7 and 9 the molecular structures have been determined by X-ray measurements. The monohydride complex trans,cis-RuHCl(PPh3)2(ampy) (11) has been prepared from RuHCl(PPh3)3 and ampy in heptane by PPh3 substitution. Compound 11 reacts with sodium isopropoxide in toluene, affording the dihydride derivative cis,trans-Ru(H)2(PPh3)2(ampy) (12) via the alkoxide route. The intermediate species cis,cis-Ru(H)2(PPh3)2(ampy) (A) has been also characterized by NMR in solution. All these complexes have been found to be highly efficient transfer hydrogenation catalysts. With the complexes cis-RuCl2(PP)(ampy) a large number of ketones (dialkyl, diaryl, and alkyl-aryl) can be quantitatively reduced to alcohols in 2-propanol and in the presence of NaOH (ketone/Ru/NaOH = 2000/1/40) with remarkably high TOF values (up to 400 000 h-1 at 50% conversion). The derivatives containing chiral diphosphines afforded rapid (TOF > 105 h-1) and enantioselective (ee up to 94%) reduction of methyl-aryl ketones using low loading of catalysts (0.05−0.01 mol %). In the absence of base the dihydride compound 12 catalyzes the transfer hydrogenation of acetophenone.
71‐1: Fractional Pixel Method for Improved Pixel‐Level Measurement and Correction (Demura) of High‐Resolution Displays (2020)

As display resolution and pixel density increase, measuring the characteristics (luminance, color) of individual display pixels becomes more difficult for existing imaging technology. This paper describes a method of display pixel measurement using fractional imaging sensor pixels to accurately measure pixel‐level luminance for emissive (OLED, microLED) display qualification and demura.
Sub-partition reuse for fast optimal motion estimation in HEVC successive elimination algorithms (2016)

In the context of motion estimation (ME) for video coding, the rate-constrained successive elimination algorithm (RC-SEA) safely eliminates candidate motion vectors while preserving the optimal candidate chosen by the block matching algorithm (BMA). This paper describes a technique for reusing ME information from rectangular to square prediction units in order to reduce the search area without altering the optimal candidate chosen by the BMA. Our experiments show that, on average, when this optimization is combined with the RCSEA in the HEVC HM encoder reference software, the number of sum of the absolute differences (SAD) operations drops by 94.9%, resulting in a speedup of 6.13x in full search mode. Although identical coding decisions cannot be guaranteed when multiple optimal solutions exist, the average impact on BD-PSNR is 0.0002 dB.
Simple and Highly <i>Z</i>-Selective Ruthenium-Based Olefin Metathesis Catalyst (2013)

A one-step substitution of a single chloride anion of the Grubbs-Hoveyda second-generation catalyst with a 2,4,6-triphenylbenzenethiolate ligand resulted in an active olefin metathesis catalyst with remarkable Z selectivity, reaching 96% in metathesis homocoupling of terminal olefins. High turnover numbers (up to 2000 for homocoupling of 1-octene) were obtained along with sustained appreciable Z selectivity (>85%). Apart from the Z selectivity, many properties of the new catalyst, such as robustness toward oxygen and water as well as a tendency to isomerize substrates and react with internal olefin products, resemble those of the parent catalyst.
New power meter concept for high energy lasers. Memorandum report (1981)

We describe a new concept for measurement of High Energy Laser (HEL) power. The technique is based upon the phenomenon of optoacoustic detection, which is a sensitive measurement of the sound waves created by absorption of a laser beam of known power with a sample of absorber material for the purpose of absorption coefficient determination. We propose that his process can be inverted to produce an absolute measurement of laser power by using a material for which the absorption coefficient at the laser frequency is sufficiently well known. We present a conceptual design and suggest studies for future development of the concept.
Noun phrase translation (2003)

We define noun phrase translation as a subtask of statistical machine translation. This enables us to build a dedicated noun phrase translation subsystem that improves over the currently best general statistical machine translation methods by incorporating special modeling and special features. 
We integrate such a system into a state-of-the-art statistical machine translation system with novel methods and show overall improvement in translation quality. We also carry out empirical linguistic studies on noun phrase translatability and the sources of translation errors.
Nanometer fluctuations of erythrocytes imaged by Hilbert phase microscopy (2005)

Packet-based JTAG for remote testing (2012)

This paper presents a proposal to express JTAG as an asynchronous packet-based protocol while maintaining full backward compatibility. This allows JTAG to transparently access remote units over high-bandwidth functional connections, a feature of special interest, for instance, in the environment of wireless telecommunication infrastructure and interfaces like CPRI or IP.
QoS harmonization for home networks (2010)

A modern home could contain a large variety of devices and all of them should be able to work together so as to bring a rich experience to the users. Quality of service (QoS) is a critical factor for measuring user satisfaction. It represents the ability to provide different priorities based on the type of the data flows or to guarantee a certain quality of performance to a particular service. Different devices may follow different protocols and each protocol has its own QoS management scheme. These QoS schemes are not necessarily compatible with one another and the inconsistency will significantly impair their efficacy. In this paper, we propose a harmonized protocol for home network, which unifies all other protocols and solves the inconsistency problem effectively.
Embedded flexible optical shear sensor (2010)

Monitoring shear stresses is increasingly important in the medical sector, where the sensors need to be unobtrusive, compact and flexible. A very thin and flexible sensor foil is presented based on the shear stress dependent coupling change of optical power between a laser and photodiode chip that were separated by a deformable sensing layer. These opto-electronic components were embedded in a very thin foil of only 40μm thick. The sensitivity and measurement range can be modified by selecting the material properties of the sensing layer. The sensor response showed to be reproducible and the influence of normal pressure on the sensor was very limited.
Voice search language model adaptation using contextual information (2016)

It has been shown that automatic speech recognition (ASR) system quality can be improved by augmenting n-gram language models with contextual information [1][2]. In the voice search domain, there are a large number of useful contextual signals for a given query. Some of these signals are speaker location, speaker identity, time of the query, etc. Each of these signals comes with relevant contextual information (e.g. location specific entities, favorite queries, recent popular queries) that is not included in the language model's training data. We show that these contextual signals can be used to improve ASR system quality. This is achieved by adjusting n-gram language model probabilities on-the-fly based on the contextual information relevant for the current voice search request. We analyze three example sources of context: location context, previously entered typed and spoken queries. We present a set of approaches we have used to improve ASR quality using these sources of context. Our main objective is to automatically, in real time, take advantage of all available sources of contextual information. In addition, we investigate challenges that come with applying our approach to a number of languages (unsegmented languages, languages with diacritics) and present solutions used.
