RISP: A Reconfigurable In-Storage Processing Framework with Energy-Awareness (2018)

Existing in-storage processing (ISP) techniques mainly focus on maximizing data processing rate by always utilizing total storage data processing resources for all applications. We find that this "always running in full gear" strategy wastes energy for some applications with a low data processing complexity. In this paper we propose RISP (Reconfigurable ISP), an energy-aware reconfigurable ISP framework that employs FPGA as data processing cells and NVM controllers. It can reconfigure storage data processing resources to achieve a high energy-efficiency without any performance degradation for big data analysis applications. RISP is modeled and then validated on an FPGA board. Experimental results show that compared with traditional host-CPU based computing RISP (with 16 channels or more) improves performance by 1.6-25.4× while saving energy by a factor of 2.2-161. Further, its reconfigurability can provide up to 77.2% additional energy saving by judiciously enabling data processing resources that are sufficient for an application.
High density magnetic recording heads for disk (1981)

New self-acting, gas-lubricated sliders developing negative pressure on their bearing surfaces, called new self-acting (NSA) head sliders, have been submitted for the attainment of high recording density in computer disk files. Their flying behaviors and recording performance are experimentally investigated. The results indicate that the NSA head slider can achieve close proximity between their bearing surfaces and a surface of a high speed rotating magnetic disk, and also can minimize wear of their bearing surfaces and the disk surface. The write/read characteristics show that the NSA head slider is more suitable for high density recording.
Activating PI3Kδ mutations in a cohort of 669 patients with primary immunodeficiency (2015)

The gene PIK3CD codes for the catalytic subunit of phosphoinositide 3-kinase δ (PI3Kδ), and is expressed solely in leucocytes. Activating mutations of PIK3CD have been described to cause an autosomal dominant immunodeficiency that shares clinical features with common variable immunodeficiency (CVID). We screened a cohort of 669 molecularly undefined primary immunodeficiency patients for five reported mutations (four gain-of-function mutations in PIK3CD and a loss of function mutation in PIK3R1) using pyrosequencing. PIK3CD mutations were identified in three siblings diagnosed with CVID and two sporadic cases with a combined immunodeficiency (CID). The PIK3R1 mutation was not identified in the cohort. Our patients with activated PI3Kδ syndrome (APDS) showed a range of clinical and immunological findings, even within a single family, but shared a reduction in naive T cells. PIK3CD gain of function mutations are more likely to occur in patients with defective B and T cell responses and should be screened for in CVID and CID, but are less likely in patients with a pure B cell/hypogammaglobulinaemia phenotype.
Access to Well-Defined Heterogeneous Catalytic Systems via Ring-Opening Metathesis Polymerization (ROMP):  Applications in Palladium(II)-Mediated Coupling Reactions (1999)

The preparation of a new heterogeneous palladium(II)-based catalyst and its homogeneous analogue and their use for Heck-type, alkyne and amine couplings are described. The heterogeneous catalytic system is based on a polymer-bound dichloropalladium di(pyrid-2-yl)amide and was prepared via ring-opening metathesis copolymerization of norborn-2-ene-5-(N,N-di(pyrid-2-yl))carbamide with 1,4,4a,5,8,8a-hexahydro-1,4,5,8-exo-endo-dimethanonaphthalene and subsequent loading of the resulting resin with palladium(II) chloride. The heterogeneous catalyst is air, moisture, and temperature stable up to 150 °C and highly active (94−99% yields) in the vinylation of aryl iodides and aryl bromides (Heck-type couplings) with turn-over numbers (TONs) of up to 210000. Even higher TON's (up to 350000) may be achieved in the arylation of alkynes. High yields (≤95%) and TONs (≤24000) may additionally be achieved in the tetrabutylammonium bromide (TBAB) assisted vinylation of aryl chlorides. Moderate yields (<65%) and TONs (<4000) are observed in the amination of aryl bromides. A soluble analogue of the heterogeneous system, N,N-di(pyrid-2-yl)acetamide palladium dichloride (2), was prepared from palladium(II) chloride and N,N-di(pyrid-2-yl)acetamide (1) and characterized by X-ray analysis. 2 crystallizes in the monoclinic space group P21/n, a = 835.0(1) pm, b = 1494.3(4) pm, c = 1199.3(2) pm, α = 90°, β = 109.05(2)°, γ = 90°, Z = 4. It served as a model compound for the elucidation of the actual geometry of the catalytic species. The unstrained geometry of 2 with almost ideal angles and bond lengths explaines the high stability of the catalytic center. The significantly higher catalytic activity of the heterogeneous system compared to the homogeneous one suggests well-defined ligand-bound catalytic sites rather than polymer-supported palladium colloids.
Investigation of electromagnetic wave propagation through one-dimensional plasma array (2015)

The characteristics of electromagnetic wave propagation through a one-dimensional plasma array were investigated experimentally and by a numerical simulation. Electromagnetic wave was incident normally on the plasma array at the wave frequency from 2 to 18 GHz. Electromagnetic wave was reflected by the plasma array regardless of the polarization when the wave frequency was sufficiently lower than the plasma frequency. Increasing the wave frequency, the reflection of the electromagnetic wave was getting smaller and electromagnetic wave was absorbed only when the electric field was perpendicular to the plasma axis. These results were caused by different schemes of interaction with electric field and electrons in plasma.

DRAM row-hammer attack reduction using dummy cells (2016)

This paper describes a low-cost and low-complexity alternative to reduce the occurrence of Row-Hammer attacks. The detection of an undesired attack is based on the use of an additional memory cell - called dummy cell -, with a larger leakage current and thus a higher sensitivity to crosstalk and coupling noise. This characteristic is achieved due to the use of a wider pass transistor and a smaller storage capacitor. One of the most relevant aspects of this solution is the involved additional low-complexity hardware, occupying less than 0.1% of the whole memory. In addition, the dummy cells can be distributed across the whole memory to hinder hackers identification. Simulations on a 65nm CMOS process were done in order to validate the proposed alternative. Process variations for coupling and interconnections were taken into account in a 64×64 memory array, so that the results keep congruence with a memory dedicate, state-of-art, 28nm process.
Influence of bacterial inoculant and substrate addition to lucerne ensiled at different dry matter contents (1992)

Abstract Field‐wilted lucerne was chopped with a forage harvester at 33 ± 1·5, 43 ± 2·0 and 54 ± 1·8% dry matter, treated and ensiled in laboratory silos during four cuttings in each of two years. Treatments were control (C), sugar addition at 2% of fresh weight (S), inoculum applied at 3 × 10 5 bacteria g −1 herbage (I), and sugar and inoculum combined (IS). Duplicate silos were opened and analysed after 1, 2, 3, (4 or 5), 7, 14 and 60 d of fermentation. The initial rate of proteolysis of lucerne protein decreased with increasing dry matter (DM) content of the lucerne, and was not influenced by the year, cutting or silage treatment. Inoculation increased ( P <0·05) the rate of pH decline for all silage dry matters, and shortened the lag time prior to pH decline with 33 and 43% dry matter silages. Sugar addition had no effect on rate of pH decline or lag time. Inoculation and sugar addition both lowered final pH, acetic acid, ammonia (NH 3 ), free amino acids (FAA) and soluble non‐protein N (NPN) in silages ( P <0·01) and increased lactic acid content with 33 and 43% dry matter silages. Only inoculation was beneficial at 54% DM with no difference between I and IS. The influence of forage characteristics (epiphytic lactic acid bacteria, buffer capacity and sugar:buffer capacity ratio) on treatment effectiveness varied with dry matter content.
Electrophysiological Effects of Ranolazine, a Novel Antianginal Agent With Antiarrhythmic Properties (2004)

Ranolazine produces ion channel effects similar to those observed after chronic amiodarone (reduced I(Kr), I(Ks), late I(Na), and I(Ca)). The actions of ranolazine to suppress EADs and reduce TDR suggest that, in addition to its antianginal actions, the drug may possess antiarrhythmic activity.
Accelerating discoveries in the proteome and genome with MALDI TOF MS (2000)

Recent developments in mass spectrometry (MS) provide scientists with an established analytical tool that addresses the demands for rapid, accurate and cost effective analyses of biomolecules. These advances clearly accelerate the rate and success of protein identification, genetic sequencing, determining biological variances and drug discovery. This review is intended to illustrate how matrix-assisted laser desorption/ionisation (MALDI) time-of-flight (TOF) MS is typically used to generate information about biomolecules under investigation. Additionally, examples will be used to describe the steps involved in preparing samples for MALDI TOF and obtaining answers through data management.
Novel Recognition Motif on Fibroblast Growth Factor Receptor Mediates Direct Association and Activation of SNT Adapter Proteins (1998)

Fibroblast growth factors (FGFs) stimulate tyrosine phosphorylation of a membrane-anchored adapter protein, FRS2/SNT-1, promoting its association with Shp-2 tyrosine phosphatase and upstream activators of Ras. Using the yeast two-hybrid protein-protein interaction assay, we show that FRS2/SNT-1 and a newly isolated SNT-2 protein directly bind to FGF receptor-1 (FGFR-1). A juxtamembrane segment of FGFR-1 and the phosphotyrosine-binding domain of SNTs are both necessary and sufficient for interaction in yeast and in vitro, and FGFR-mediated SNT tyrosine phosphorylation in vivo requires these segments of receptor and SNT. Our findings establish SNTs as direct protein links between FGFR-1 and multiple downstream pathways. The SNT binding motif of FGFR-1 is distinct from previously described phosphotyrosine-binding domain recognition motifs, lacking both tyrosine and asparagine residues.
Threat analysis and attacks modelling in routing towards IoT (2017)

Internet of Things (IoT) promises major role in terms of medium and information transaction, management computing, and security from the beginning of the 21st century. IoT plays an important role in daily life. Routing in IoT is the serious problem because existing routing is not designed to meet current demands in the Internet. Today routing is a continuous strain in terms of the number of threats, performance, security, reliability and scalability. Routing is a fundamental mechanism in communication network and its security is critical to ensure availability and to prevent attacks. Developing and expanding secure routing mechanism is still a challenge in IoT. This paper presents various routing techniques towards IoT. Furthermore, explain the routing process because in which information is exchanged with the help of the routers. This paper also explains the different types of attack modelling. Attacks are possible in routing because of minimum security in IoT, the attacker attacks the routing process to misuse of data. Some attacks are diverting traffic to an attacker controlled router, i.e. route-hijacking and denial of service attacks exploiting routing mechanism.

Dendritic cells derived exosomes migration to spleen and induction of inflammation are regulated by CCR7 (2017)

Mature dendritic cells (DCs) home to secondary lymphoid organs through CC chemokine receptor 7 (CCR7). Exosomes derived from DCs (DC-exos) are reported to migrate to spleen and induce inflammation in vivo. In this study, we demonstrated that mature bone marrow DC-exos can activate immature DC and T cells in vitro. Then we intravenously injected DC-exos into C57BL/6 mice, observing that mature DC-exos accumulated more in spleen than immature DC-exos. These DC-exos in spleen could be uptaken by splenetic DCs and T cells and induce an inflammatory response. We further showed that the increased accumulation of mature DC-exos in spleen was regulated by CCR7, whose reduction led to a decrease of accumulation in spleen and attenuated inflammatory response in serum. These data provide us a new perspective to comprehensively understand exosomes, which might inherit some special functions from their parent cells and exert these functions in vivo.
Stress Corrosion Cracking of Sensitized AA5083 in NaCl Solution (2011)

Abstract In this study, commercial AA5083 aluminum alloy was sensitized at 175oC in order to create a two-phase microstructure that is highly susceptible to stress corrosion cracking (SCC). To characterize the SCC behavior of these sensitized AA5083 alloy in NaCl solution, open circuit continuous immersion SCC tests were conducted on pre-cracked double cantilever beam (DCB) specimens with an initial stress intensity factor (KI) of 15 ksiin (16.5 MPam) in NaCl solutions with five different concentrations, i.e. 0.01, 0.1, 0.6, 1, and 3 mol/L. Three SCC characteristics, incubation time, initial crack growth rate, and total crack growth, were found strongly dependent on solution concentration: incubation time decreased with increasing NaCl concentration, while both initial crack growth rate and total crack growth increased with solution concentration. A linear relationship between initial crack growth rate and NaCl concentration, as well as between total crack growth and NaCl concentration, was also found on specimens sensitized for 10 days (240 hours). Since the growth of cracks under fixed loading line displacement decreases the applied K, the arrest of cracks that limits the total crack growth may be interpreted as a concentration dependent threshold stress intensity, KISCC. Fracture surfaces produced by SCC in NaCl solutions with different concentrations and on different values of K, when investigated by scanning electron microscopy, all demonstrated intergranular cracking with similar characteristics. Discussion centers on relative contributions to SCC from mechanical driving forces and chemical driving forces.
Generation of White Light by Hybridization of Red–Green–Blue–Luminescent Materials (2019)

Herein, the fabrication of a white luminescent material with photoluminescence (PL) in the region ranging from 350 to 900 nm is reported. Formation of the luminescent material is achieved simply by the high‐temperature (1100 °C) annealing of silicon‐rich oxide nanowires containing a ZnO phase, which are grown by exposing a Zn film to Si and O plasma generated using a mixture of N 2 O and SiH 4 gases at a low temperature (380 °C). The PL spectral response is easily tuned by varying the mixing ratio of the two gases or the Zn film thickness. The generation of white luminescence can be attributed to the hybridization of Si nanocrystals (red), silicon oxide (green), and ZnO (blue)‐based materials.
Room Temperature Gas Sensing of Two-Dimensional Titanium Carbide (MXene) (2017)

Wearable gas sensors have received lots of attention for diagnostic and monitoring applications, and two-dimensional (2D) materials can provide a promising platform for fabricating gas sensors that can operate at room temperature. In the present study, the room temperature gas-sensing performance of Ti<sub>3</sub>C<sub>2</sub>T<sub>x</sub> nanosheets was investigated. 2D Ti<sub>3</sub>C<sub>2</sub>T<sub>x</sub> (MXene) sheets were synthesized by removal of Al atoms from Ti<sub>3</sub>AlC<sub>2</sub> (MAX phases) and were integrated on flexible polyimide platforms with a simple solution casting method. The Ti<sub>3</sub>C<sub>2</sub>T<sub>x</sub> sensors successfully measured ethanol, methanol, acetone, and ammonia gas at room temperature and showed a p-type sensing behavior. The fabricated sensors showed their highest and lowest response toward ammonia and acetone gas, respectively. The limit of detection of acetone gas was theoretically calculated to be about 9.27 ppm, presenting better performance compared to other 2D material-based sensors. The sensing mechanism was proposed in terms of the interactions between the majority charge carriers of Ti<sub>3</sub>C<sub>2</sub>T<sub>x</sub> and gas species.
Surface Antigens of the Syphilis Spirochete and Their Potential as Virulence Determinants (1997)

A unique physical feature of Treponema pallidum, the venereally transmitted agent of human syphilis, is that its outer membrane contains 100-fold less membrane-spanning protein than the outer membranes of typical gram-negative bacteria, a property that has been related to the chronicity of syphilitic infection. These membrane-spanning T. pallidum rare outer membrane proteins, termed TROMPs, represent potential surface-exposed virulence determinants and targets of host immunity. Only recently has the outer membrane of T. pallidum been isolated and its constituent proteins identified. Five proteins of molecular mass 17-, 28-, 31-, 45-, and 65-kDa were outer membrane associated. The 17- and 45-kDa proteins, which are also present in greater amounts with the T. pallidum inner membrane protoplasmic cylinder complex, had been previously characterized lipoproteins and are, therefore, not membrane-spanning but rather membrane-anchored by their lipid moiety. In contrast, the 28-, 31-, and 65-kDa proteins are exclusively associated with the outer membrane. Both the purified native and an Escherichia coli recombinant outer membrane form of the 31-kDa protein, designated Tromp1, exhibit porin activity, thereby confirming the membrane-spanning outer membrane topology of Tromp1. The 28-kDa protein, designated Tromp2, has sequence characteristics in common with membrane-spanning outer membrane proteins and has also been recombinantly expressed in E. coli, where it targets exclusively to the E. coli outer membrane. The 65-kDa protein, designated Tromp3, is present in the least amount relative to Tromps1 and 2. Tromps 1, 2, and 3 were antigenic when tested with serum from infection and immune syphilitic rabbits and humans. These newly identified TROMPs provide a molecular foundation for the future study of syphilis pathogenesis and immunity.
Adaptively-biased capacitor-less CMOS low dropout regulator with direct current feedback (2006)

A capacitor-less low dropout regulator (LDR) with direct current feedback is proposed A symmetrically-matched voltage mirror in sensing the load current is employed, and gives excellent line and load regulations. The dynamic biasing results in an LDR with pole-tracking that Wends the bandwidth of the loop gain at high load currents. The LDR was fabricated in a 0.35 mu m CMOS process with an active area of 0.11mm(2), and measurement results corroborated well with both analysis and simulation.
Effect of Mg on the Formation of Periodic Layered Structure during Double Batch Hot Dip Process in Zn-Al Bath (2021)

The article presents the results of studies on the influence of Mg on the formation of the periodic layered structure of the Zn-AlMg coatings. These coatings were produced by the double batch hot dip method in a Zn bath and then in a Zn-Al(Mg) bath with a content of 15, 23, 31 wt.% Al and 3, 6 wt.% Mg. The microstructure of the coatings (OM, SEM) was revealed and the phase composition (XRD) obtained in two-component Zn-Al baths and Zn-AlMg baths were determined. The periodic layered structure was found to consist of alternating FeAl<sub>3</sub> phase layers and a bath alloy (Zn + Al + Mg). Moreover, it was observed that the addition of 3 wt.% Mg reduces the thickness of the coating in baths containing 23 and 31 wt.% Al. However, the addition of 6 wt.% Mg causes complete disappearance of periodic layered structure in a bath with 23 wt.% Al. In a bath with a content of 31 wt.% Al the addition of 6 wt.% Mg creates a compact layer consisting of the FeAl<sub>3</sub> phase containing the precipitation of the MgZn<sub>2</sub> phase and Fe<sub>2</sub>Al<sub>5</sub> phase. Such a structure of the coating transition layer limits the growth of the periodic layered structure in the coating.
Combinatorial Generation of Chemical Diversity by Redox Enzymes in Chaetoviridin Biosynthesis (2016)

Chaetoviridins constitute a large family of structurally related secondary metabolites isolated from Chaetomium fungi. To elucidate the biosynthesis pathway and understand how the chemical diversity of chaetoviridins is generated, gene deletion and in vitro characterization of the four post-PKS modifications enzymes were undertaken. CazL and CazP were identified to have substrate promiscuity that facilitates the formation of nonchlorinated analogues. In addition, enzymatic oxidation and reduction combined with spontaneous dehydration and lactonization of the intermediates further expand the chemical diversity.
