Predictive analog-digital-conversion in fiber optics communication (2014)

Advances in digital hardware had enabled a new generation of fiber optics communication receivers. Extensive digital-signal-processing (DSP) allows compensating for channel impairments and, in turn, scaling up in data rate. One of the main challenges in modern receivers is implementing a high-rate, high-precision analog-to-digital-converter (ADC) that could meet the system requirements. Since ADCs technology is usually far from the highest rates available, reducing required resolution is imperative for present and future receivers. In this paper a predictive quantization approach is investigated. We show that common optical channel and components impairments introduce sufficient waveform correlation, which may be leveraged to significantly improve the Analog-to-digital-conversion process. Simulation results had shown that implementing low-complexity predictive quantization systems improves SNR performance, and may be used to reduce required resolution.
Perfluoroalkylation of Unactivated Alkenes with Acid Anhydrides as the Perfluoroalkyl Source (2016)

An efficient perfluoroalkylation of unactivated alkenes with perfluoro acid anhydrides was developed. Copper salts play a crucial role as a catalyst to achieve allylic perfluoroalkylation with the in situ generated bis(perfluoroacyl) peroxides. Furthermore, carboperfluoroalkylation of alkene bearing an aromatic ring at an appropriate position on the carbon side chain was found to proceed under metal-free conditions to afford carbocycles or heterocycles bearing a perfluoroalkyl group. This method, which makes use of readily available perfluoroalkyl sources, offers a convenient and powerful tool for introducing a perfluoroalkyl group onto an sp(3) carbon to construct synthetically useful skeletons.
INHIBITION OF TISSUE FACTOR-DEPENDENT AND -INDEPENDENT COAGULATION BY CELL SURFACE EXPRESSION OF NOVEL ANTICOAGULANT FUSION PROTEINS (1999)

These results suggest that these novel anticoagulant molecules may prove useful therapeutic agents for gene therapy or for transgenic expression in animals whose organs may be used for cliniCal xenotransplantation.
Superscalar Processor with Multi-Bank Register File (2006)

Register files in highly parallel superscalar processors tend to have large chip area and many access ports. This trend causes problems with chip-size, access time and power consumption. As one of the methods for solving these problems, we have proposed a multi-bank register file which realizes small area, high speed and low power consumption. We have proved effectiveness of this method by software simulation, and by detail designing it as synthesizable Verilog-HDL description with a full custom designed multi-bank register file. In this paper, we show the detail architecture of a superscalar processor with the multi-bank register file and its evaluation results.
Lack of BLV and PTLV DNA sequences in the majority of patients with large granular lymphocyte leukaemia (2000)

The primate T-cell lymphoma/leukaemia viruses (PTLV) and bovine leukaemia virus (BLV) comprise a unique genus of retroviruses, infection with which induces seroreactivity in the host against conserved epitopes in their p24 gag and gp21 env cognate proteins. Herein, we have confirmed this serocrossreactivity. Patients with large granular lymphocyte (LGL) leukaemia have frequent seroreactivity to the p24 and gp21 env proteins of human T-cell lymphoma/leukaemia virus I (HTLV-I), one of the species in the genus. However, only a small minority of patients are actually infected with prototypic HTLV-I or HTLV-II, another species within the group. In an attempt to determine whether LGL leukaemia might be associated with other members of the PTLV/BLV genus, we examined the peripheral blood mononuclear cell DNA of 22 HTLV p24 and/or gp21 seropositive LGL leukaemia patients via PCR using degenerate and specific primer pair/probe systems capable of detecting all known members of the PTLV/BLV genus. None of the samples was positive. These data indicate that although HTLV-II may be associated with some cases of LGL leukaemia most patients are not infected with a PTLV or BLV virus.
Multiplexing in Multi-Reflecting TOF MS (2016)

The paper presents an overview of original inventions, development and experimental results by the group of authors in the area of multi-reflecting time-of-flight mass spectrometry with Folded Flight Path (FFP®) (MR-TOFMS) with main focus on multiplexing methods for improving the analysis throughput, i.e. the amount of information per time unit. MR-TOF provides panoramic spectra (virtue of TOFMS), while significantly enhancing resolving power, thus, providing yet more information. Resolving power R=500,000 is demonstrated to resolve isobars and to improve mass accuracy to sub-ppm level. Encoded Frequent Pulsing (EFPTM) method improves sensitivity, expands dynamic range and opens multiple incarnations of parallel and fast tandem methods of analysis based on using ion traps, TOFMS and ion mobility for rapid and lossless parent ion separations.
Experimental immunization of sows with inactivated transmissible gastroenteritis (TGE) virus. (1971)

Four sows were immunized with inactivated TGE virus. The virus was either propagated in pig kidney cell cultures, or obtained from the intestines of experimentally infected gnotobiotic pigs, and inactivated by treatment with beta-propiolactone. The inactivated virus preparations were administered to sows by intramammary inoculation. Two sows received two inoculations; the other two sows received three inoculations of inactivated virus. The antibody responses in the serum and milk were determined and piglets nursing the sows were experimentally challenged with virulent TGE virus. Three inoculations of the virus preparation stimulated much higher levels of serum and milk antibody than did two inoculations. A schedule of three inoculations of sows with inactivated TGE virus was effective in stimulating protection against TGE for piglets nursing these sows.
INTEGRATED VERTICAL PARALLEL PLATE CAPACITIVE HUMIDITY SENSOR (2010)

An integrated capacitive humidity sensor on-chip with CMOS interface electronics is demonstrated to have a sensitivity of 0.31% change in capacitance per percent relative humidity, 72% higher than the highest previously demonstrated in an integrated sensor. The vertical parallel-plate sensor made in CMOS is a high sensitivity topology that had not been previously integrated. The sensitized dielectric between two metal electrodes is formed by first forming a cavity by etching an intermediate layer of metal in the CMOS stack and then filling the cavity with polymer through inkjet deposition. This topology is demonstrated with polyimide to make a humidity sensor, but with appropriate polymer selection can also be used to sense other chemicals.
Multiple Optical Elastography Techniques Reveal the Regulation of Corneal Stiffness by Collagen XII (2022)

Our approach suggests that the absence of collagen XII significantly softens the cornea. Although both optical coherence elastography techniques showed an expected increase in corneal stiffness as a function of IOP, Brillouin microscopy did not show such a relationship, suggesting that the Brillouin longitudinal modulus may not be affected by changes in IOP. Future work will focus on multimodal biomechanical models, evaluating the effects of other collagen types on corneal stiffness, and in vivo measurements.

Synthetic optical holography with nonlinear-phase reference (2014)

Synthetic optical holography (SOH) provides efficient encoding of the complex optical signal, both amplitude and phase, for scanning imaging methods. Prior demonstrations have synthesized reference fields with a plane-wave-like linear variation of the phase with position. To record large images without probe-mirror synchronization, a long-travel, closed-loop reference mirror stage has been required. Here we present SOH with a synthetic reference wave with sinusoidal spatial variation of the phase. This allows the use of open loop, limited mirror travel range in SOH, and leads to a novel holographic inversion algorithm. We validate the theory with scans of graphene grain boundaries from a scanning near-field optical microscope, for which SOH has been shown to drastically increase scan speeds [Nat. Commun. 5, 3499 (2014)].
3D microwave modules for space applications (2002)

This paper describes the design, manufacturing and measurement of 3D microwave modules. The vertical interconnection between stacked circuits is based on an shielded homogeneous coplanar line with a 90/spl deg/ vertical structure. The fabrication of these modules is in relation with the "MultiChip Module Vertical" technology, originally developed for digital applications. The electrical measurement in the Ku-band demonstrates very good results.
Quinone-Based Flow Battery with Increased Open Circuit Voltage (2014)

Quinone-based flow batteries exhibit rapid redox kinetics, contain no electrocatalyst and use very inexpensive redox active materials [1]. Consequently, they appear to be very attractive candidates for inexpensive, large-scale electrical energy storage. We compare the performance of several substituted quinone/hydroquinone redox couples in an aqueous flow battery. We show that various substitutional groups can alter the electrochemical properties of the quinone, which in turn affects the performance of the flow battery. One substituted quinone at the negative electrode, when combined with Br 2 /HBr at the positive electrode, exhibits an open circuit voltage exceeding 1.0 V and a peak galvanic power density exceeding 0.24 W/cm 2 when fully charged. Fig. 1. Polarization plot (a) and galvanic power densities (b) of a substituted quinone-bromine flow battery at various states of charge (SOC). The electrodes are Toray carbon paper with no electrocatalyst. The membrane is Nafion 212. The negative side is 0.5 M substituted quinone in 1 M sulfuric acid. The positive electrode is 1.5 M hydrobromic acid, 0.25 M bromine.
Diagnosis of Partial Body Radiation Exposure in Mice Using Peripheral Blood Gene Expression Profiles (2010)

In the event of a terrorist-mediated attack in the United States using radiological or improvised nuclear weapons, it is expected that hundreds of thousands of people could be exposed to life-threatening levels of ionizing radiation. We have recently shown that genome-wide expression analysis of the peripheral blood (PB) can generate gene expression profiles that can predict radiation exposure and distinguish the dose level of exposure following total body irradiation (TBI). However, in the event a radiation-mass casualty scenario, many victims will have heterogeneous exposure due to partial shielding and it is unknown whether PB gene expression profiles would be useful in predicting the status of partially irradiated individuals. Here, we identified gene expression profiles in the PB that were characteristic of anterior hemibody-, posterior hemibody- and single limb-irradiation at 0.5 Gy, 2 Gy and 10 Gy in C57Bl6 mice. These PB signatures predicted the radiation status of partially irradiated mice with a high level of accuracy (range 79-100%) compared to non-irradiated mice. Interestingly, PB signatures of partial body irradiation were poorly predictive of radiation status by site of injury (range 16-43%), suggesting that the PB molecular response to partial body irradiation was anatomic site specific. Importantly, PB gene signatures generated from TBI-treated mice failed completely to predict the radiation status of partially irradiated animals or non-irradiated controls. These data demonstrate that partial body irradiation, even to a single limb, generates a characteristic PB signature of radiation injury and thus may necessitate the use of multiple signatures, both partial body and total body, to accurately assess the status of an individual exposed to radiation.
A "flying-adder" architecture of frequency and phase synthesis with scalability (2002)

Most of today's digital designs, from small-scale digital block designs to system-on-chip (SoC) designs, are based on "synchronous" design principle. Clock is the most important issue in these designs. Frequency and phase synthesis is closely related to the clock generation. A frequency and phase synthesis technique based on phase-locked loop is proposed in that delivers high performance, easy integration, and high stability. However, there are problems associated with this architecture, such as: 1) its highest deliverable frequency is limited by the speed of the accumulator and 2) the phase synthesis circuitry will not work well in certain ranges (dead zone) and in certain conditions (dual stability). This paper presents an improved architecture that addresses these problems. The new frequency synthesis circuitry has scalability for higher output frequency. It also has an internal node whose frequency is twice that of output signal. When duty cycle is not a concern, this signal can be used directly as clock source. The new phase synthesis circuitry is free of "dead zone" and "dual stability." The improved architecture has better performance, is simpler to implement, and is easier to understand.
An enzymic creatinine assay and a direct ammonia assay in coated thin films. (1983)

We developed a thin-film enzymic assay for creatinine that makes use of creatinine iminohydrolase (EC 3.5.4.21) to convert creatinine to N-methylhydantoin and ammonia. The ammonia diffuses through a semipermeable layer and is quantitated by reaction with bromphenol blue. A paired analysis of the sample on a separate coating without the enzymic reaction measures endogenous ammonia and, for samples with normal concentrations of ammonia, allows accurate determination of serum creatinine to 150 mg/L without dilution. Results of this assay (y) compare well with those by a liquid-chromatographic comparison assay (x) by linear regression (slope = 0.935, intercept = 1.13 mg/L, r2 = 0.995). It is insensitive to many substances, such as ketones and keto acids, that interfere with conventional assays. Results of the ammonia assay (y) correlate well with those by a semi-automated enzymic assay (x) based on glutamate dehydrogenase (slope = 1.068, intercept = 17.3 mumol/L, r2 = 0.985).
Isolation of Vinblastine in Callus Culture with Differentiated Roots of<i>Catharanthus roseus</i>(L). G. Don (1987)

The callus initiated from Madagascar periwinkle, Catharanthus roseus, with 1.0 mg/liter naphthaleneacetic acid and 0.1 mg/liter kinetin was brown and tight, and formed many hairy roots. The formation of vinblastine in the callus culture with differentiated roots was confirmed by high-performance liquid chromatography and mass spectrometry.
Wireless Neuromodulation at Submillimeter Precision via a Microwave Split-Ring Resonator (2022)

Abstract Microwaves, with wavelengths on the order of millimeters, have centimeter-scale penetration depth and have been shown to reversibly inhibit neuronal activity. Yet, microwaves alone do not provide sufficient spatial precision to modulate target neurons without affecting surrounding tissues. Here, we report an implantable split-ring resonator (SRR) that generates a localized and enhanced microwave field at the gap site with submillimeter spatial precision. The SRR breaks the microwave diffraction limit and greatly enhances the efficiency of microwave inhibition. With the SRR, microwaves at dosages below the safe exposure limit are shown to inhibit neurons within 1 mm from the gap site. Application of the microwave SRR to suppress seizures in an in vivo model of epilepsy is demonstrated.
Domain adaptation for cross-lingual query classification using search query logs and document classification (2013)

Query Intent classifier is used by a search engine to classify an online search query whether having a certain type of intent such as adult intent or commercial intent. Training such classifiers for each language is a supervised machine learning task that requires a large amount of labeled training queries. The manual annotation of training queries for each new emerging language using human judges is expensive, error-prone and time consuming. In this paper, we leverage the existing query classifiers in a source language and the abundant unlabeled queries in the query log of the underserved target language to reduce the cost and automate the training data annotation process. The most clicked search results of a query are used to predict the intent of this query instead of human judges. Document classifier is trained on hidden topics extracted by latent semantic indexing from the translation of source language documents into the target language. The experimental results, using English as the source language and Arabic as the target one, show that the proposed unsupervised method has trained support vector machines as Arabic query classifiers to detect both commercial and health intent without need for human-judged Arabic queries. The unsupervised classifiers outperform the classifiers based on direct query translation and the decision fusion of both classifier is superior.
Durability and Activity of Modified Nickel Anode for Alkaline Water Electrolysis (2014)

Alkaline water electrolysis (AWE) produces highly pure hydrogen with simple and less expensive configuration. Conventional anode is Ni based material, and it is stable in steady electrolysis; however it deteriorates in some cases with the fluctuation of electric power supply, for example where renewable energy such as wind or solar power. To improve durability under potential fluctuation, we have investigated the catalytic activity and durability of oxygen evolution reaction (OER) for three types of Ni based electrodes with and without pre-oxidation under potential cycling. Surface oxidized nickel anode was more stable than nickel anode, but it is less active than nickel in high current density region because of electronic resistance of surface oxide. Lithium doped surface oxide improved electronic conductivity, and it had the better activity and durability than those of both nickel and surface oxidized nickel.
INTERNAL FRUIT QUALITY: HOW TO INFLUENCE IT, HOW TO DEFINE IT (2006)

Fruit quality is influenced by cultural management in field, by the fruit picking time and by the storage strategy. The choice of the best techniques and strategies to enhance fruit quality is difficult, and even more complicate is the definition of the internal fruit quality changes occurring in pre- and post-harvest conditions. In fact, internal fruit quality is strictly related to the changes occurring during the ripening and maturation syndrome. Define them with accuracy would allow to verify the techniques adopted validity, to monitor the evolution of the ripening in field and in storage and finally to offer a uniform fruit quality to the consumers. Fruit internal quality is represented by the fruit texture, the sugars and organic acids content, the flavour, etc. Although a precise definition of the quality would require equipped laboratory and knowledgeable personnel, the standard techniques for assessing fruit quality are quite simple (refractometer and penetrometer for flesh soluble solids content and flesh firmness; titration for acidity, etc). These determinations are carried out on samples of a limited number of fruit, often not representative of all the fruit, but give the possibility to have real-time information. However, recently, the availability of non-destructive techniques to assess fruit quality, also offer real-time information, allow to determine quality traits on a high number or even on all the fruit, to repeat the analyses on the same samples monitoring their physiological evolution, to determine with the same measurement a number of information on several fruit quality parameters. Here are reported examples on how the internal fruit quality can be influenced (harvest time, 1-MCP applications, storage strategy) and the possibility offered by NIRs (near infrared spectroscopy) and electronic-nose non-destructive devices to monitor and define fruit quality changes of some fruit specie in pre- and post-harvest situations.
Digital Optical Linear 3 X 3 Bit Combinatorial Systolic Multiplication Array (1986)

This manuscript represents the second paper in a series of publications describing alternative combinatorial logic based optical computing architectures. Within the first paper titled "Combinatorial Logic Based Optical Computing," justification for combinatorial logic is initially debated through the coupled use of extensive optical interconnects with the natural "and-or-invert" capability of most every optical system.1 This is followed by a simple example of an optical "text" processor, a word and phrase comparitor which can be used for massive text look-up and search. This demonstrates the ability to design a wide range of digital optical architectures capable of performing numerous, if not myriad, sets of digital functions other than mathmatical. The original paper continues to describe a digital optical full adder enhanced by the full global broadcast capability of optics. Finally, a 2 x 2 bit systolic multiplier is described for matrix processing where the limitations of the DMAC algorithm are finally overcome.2-5 The output is thus a full 4 bit binary weighted result.
Fast direction-aware proximity for graph mining (2007)

In this paper we study asymmetric proximity measures on directed graphs, which quantify the relationships between two nodes or two groups of nodes. The measures are useful in several graph mining tasks, including clustering, link prediction and connection subgraph discovery. Our proximity measure is based on the conceptof escape probability. This way, we strive to summarize the multiple facets of nodes-proximity, while avoiding some of the pitfalls to which alternative proximity measures are susceptible. A unique feature of the measures is accounting for the underlying directional information. We put a special emphasis on computational efficiency, and develop fast solutions that are applicable in several settings. Our experimental study shows the usefulness of our proposed direction-aware proximity method for several applications, and that our algorithms achieve a significant speedup (up to 50,000x) over straight forward implementations.
Coded Multidimensional Pulse Amplitude Modulation for Ultra-high-speed Optical Transmission (2011)

We propose a coded N-dimensional pulse-amplitude modulation (ND-PAM) suitable for ultra-high-speed serial optical transport. The polarization-multiplexed-ND-PAM significantly outperforms corresponding polarization-multiplexed-QAM counterpart in terms of OSNR sensitivity (> 4 dB at symbol rate 31.25 GS/s), while enabling beyond 400 Gb/s transmission.
