Minimizing instrument calibration error to reduce the effect of variability on PET/CT SUV measurements (2009)

Hexavalent chromium is a highly toxic substance, which will pose a serious threat to human life and health and the entire ecosystem. Therefore, it is crucial to establish a simple and rapid detection method for hexavalent chromium. In this work, we fabricated bovine serum albumin-stabilized silver nanocluster (BSA-Ag<sub>13</sub> NC) which exhibited photoresponsive oxidase-like activity, catalyzing the oxidation of colorless 3,3',5,5'-tetramethylbenzidine (TMB) to the blue oxidized state TMB (oxTMB) in a short time. Interestingly, 8-hydroxyquinoline (8-HQ) can significantly inhibit the color reaction of TMB oxidation while Cr(VI) can interact specifically with 8-HQ to restore this chromogenic reaction. Based on the above facts, a colorimetric sensing system for detecting Cr(VI) was developed. The sensing system shows a wide linear range, and good selectivity, with a low detection limit of 2.32 nM. Moreover, this sensing system could be successfully applied to the detection of Cr(VI) in lake water, tap water, and sewage with satisfactory results.
Activation of Notch and Myc Signaling via B-cell–Restricted Depletion of Dnmt3a Generates a Consistent Murine Model of Chronic Lymphocytic Leukemia (2021)

Chronic lymphocytic leukemia (CLL) is characterized by disordered DNA methylation, suggesting these epigenetic changes might play a critical role in disease onset and progression. The methyltransferase <i>DNMT3A</i> is a key regulator of DNA methylation. Although <i>DNMT3A</i> somatic mutations in CLL are rare, we found that low <i>DNMT3A</i> expression is associated with more aggressive disease. A conditional knockout mouse model showed that homozygous depletion of <i>Dnmt3a</i> from B cells results in the development of CLL with 100% penetrance at a median age of onset of 5.3 months, and heterozygous <i>Dnmt3a</i> depletion yields a disease penetrance of 89% with a median onset at 18.5 months, confirming its role as a haploinsufficient tumor suppressor. B1a cells were confirmed as the cell of origin of disease in this model, and <i>Dnmt3a</i> depletion resulted in focal hypomethylation and activation of <i>Notch</i> and <i>Myc</i> signaling. Amplification of chromosome 15 containing the <i>Myc</i> gene was detected in all CLL mice tested, and infiltration of high-<i>Myc</i>-expressing CLL cells in the spleen was observed. Notably, hyperactivation of <i>Notch</i> and <i>Myc</i> signaling was exclusively observed in the <i>Dnmt3a</i> CLL mice, but not in three other CLL mouse models tested (<i>Sf3b1-Atm</i>, <i>Ikzf3</i>, and <i>MDR</i>), and <i>Dnmt3a</i>-depleted CLL were sensitive to pharmacologic inhibition of <i>Notch</i> signaling <i>in vitro</i> and <i>in vivo</i>. Consistent with these findings, human CLL samples with lower <i>DNMT3A</i> expression were more sensitive to <i>Notch</i> inhibition than those with higher <i>DNMT3A</i> expression. Altogether, these results suggest that <i>Dnmt3a</i> depletion induces CLL that is highly dependent on activation of <i>Notch</i> and <i>Myc</i> signaling. SIGNIFICANCE: Loss of <i>DNMT3A</i> expression is a driving event in CLL and is associated with aggressive disease, activation of <i>Notch</i> and <i>Myc</i> signaling, and enhanced sensitivity to <i>Notch</i> inhibition.

Graph learning by a set of automata (2014)

Graph learning by automata is a basic task in many applications. Among these applications are verification and testing of software and hardware systems, network exploration including Internet and GRID basing on formal models. The system or network model, in the final analysis, is a transition graph with properties to be examined. In the recent years the size of the systems and networks in everyday use and, consequently, the size of their models and graphs to be learned grows constantly. Problems arise when graph exploration by a single automaton (computer) either requires a lot of time, or a lot of computer memory, or both. Therefore, there is a task of parallel and distributed graph exploration. This task is formalized as graph learning by a set of automata (a set of computers with sufficient total memory working in parallel). This paper covers the solution of this task. First of all the behavior of the automaton on the graph is formalized. Then the algorithm of the graph learning is described in detail. The estimation of the algorithm is O ( m + nD ). Some ways of possible optimization is discussed.
Activation of Ultrathin Films of Hematite for Photoelectrochemical Water Splitting via H2 Treatment (2015)

Thermal treatment of ultrathin films of hematite (α-Fe2 O3 ) under an atmosphere of 5 % H2 in Ar is presented as a means of activating α-Fe2 O3 towards the photoelectrochemical splitting of water. Spin-coated films annealed in air exhibited no photoactivity, whereas films treated in hydrogen exhibited a photocurrent response. X-ray photoelectron spectroscopy and UV/Vis absorption spectroscopy results showed that the H2 -treated films contain oxygen vacancies, which suggests improved charge transport. However, Tafel slopes, scan-rate dependent measurements, and kinetic analyses performed by using H2 O2 as a hole scavenger suggested that surface modification may also contribute to their induced photoactivity. Electrochemical impedance spectroscopy results revealed the buildup of a surface trap capacitance at the point of photocurrent onset for the hydrogen-treated films under illumination. A decrease in charge trapping resistance was also observed, which suggests improved transport of charges away from the surface.
Memristor Multiport Readout: A Closed-Form Solution for Sneak Paths (2014)

In this paper, we introduce for the first time, a closed-form solution for the memristor-based memory sneak paths without using any gating elements. The introduced technique fully eliminates the effect of sneak paths by reading the stored data using multiple access points and evaluating a simple addition/subtraction on the different readings. The new method requires fewer reading steps compared to previously reported techniques, and has a very small impact on the memory density. To verify the underlying theory, the proposed system is simulated using Synopsys HSPICE showing the ability to achieve a 100% sneak-path error-free memory. In addition, the effect of quantization bits on the system performance is studied.

Self-testing of sigma-delta MEMS sensors using BIMBO (2007)

This paper deals with the test of sigma-delta MEMS sensors thanks to BIMBO, an identification method based on binary observations. We show how this method may be used in order to estimate the parameters of the sensing cell and of the associated analog electronics. The principle of the method and its theoretical properties are briefly presented and its pros and cons are discussed. Two approaches for the test of sigma-delta sensors are then presented and compared.

Molecular Cloning and Expression of a Novel Human β-Gal-3-O-sulfotransferase That Acts Preferentially onN-Acetyllactosamine in N- andO-Glycans (2001)

A novel cDNA-encoding galactose 3-O-sulfotransferase was cloned by screening the expressed sequence tag data base using the previously cloned cDNA encoding a galactosyl ceramide 3-O-sulfotransferase, which we term Gal3ST-1. The newly isolated cDNA encodes a novel 3-O-sulfotransferase, termed Gal3ST-3, that acts exclusively on N-acetyllactosamine present in N-glycans and core2-branched O-glycans. These conclusions were confirmed by analyzing CD43 chimeric proteins in Chinese hamster ovary cells expressing core2 beta1,6-N-acetylglucosaminyltransferase. The acceptor specificity of Gal3ST-3 contrasts with that of the recently cloned galactose 3-O-sulfotransferase (Honke, K., Tsuda, M., Koyota, S., Wada, Y., Iida-Tanaka, N., Ishizuka, I., Nakayama, J., and Taniguchi, N. (2001) J. Biol. Chem. 276, 267-274), which we term Gal3ST-2 in the present study because the latter enzyme can also act on core1 O-glycan and type 1 oligosaccharides, Galbeta1-->3GlcNAc. Moreover, Gal3ST-3 but not Gal3ST-2 can act on Galbeta1-->4(sulfo-->6)GlcNAc, indicating that disulfated sulfo-->3Galbeta1-->4(sulfo-->6) GlcNAc-->R may be formed by Gal3ST-3 in combination with GlcNAc 6-O-sulfotransferase. Although both Gal3ST-2 and Gal3ST-3 do not act on galactosyl ceramide, Gal3ST-3 is only moderately more homologous to Gal3ST-2 (40.1%) than to Gal3ST-1 (38.0%) at the amino acid level. Northern blot analysis demonstrated that transcripts for Gal3ST-3 are predominantly expressed in the brain, kidney, and thyroid where the presence of 3'-sulfation of N-acetyllactosamine has been reported. These results indicate that the newly cloned Gal3ST-3 plays a critical role in 3'-sulfation of N-acetyllactosamine in both O- and N-glycans.
Post‐plasma‐spraying heat treatment of the HA coating/Ti‐6Al‐4V implant system (1993)

The metal/ceramic interface that constitutes an important part of the plasma-sprayed HA-coated Ti-6A1-4V system may, in fact, represent the "weak link" in the implant design. A post-plasma-spray heat treatment to enhance chemical bonding at the metal/ceramic interface and, hence, improve the mechanical properties (interface fracture toughness and tensile coating adhesion strength) of the plasma-sprayed implant system does show promise. In preliminary heat treatment studies, however, any improvements realized were lost due to the chemical instability of the coating in a moisture-laden environment, with a concomitant loss in bonding properties. This deterioration in properties appears to be related to environmentally assisted crack growth as influenced by processing conditions. Still, an ability to improve HA/Ti-6A1-4V bonding through enhanced diffusion bonding was demonstrated, warranting further heat treatment studies involving atmosphere control during processing.

Current Detection Type SPR Sensor using AU Grating and Backside Illumination (2019)

In this paper, we report on miniaturization of chemical sensor using Surface Plasmon Resonance (SPR). This sensor has an Au grating on a surface of an n-Si wafer. The Au grating enables excitation SPR that can be detected electrically with the device. We demonstrated a backside illumination method to excite SPR so that the excitation light was introduced from the n-Si side, instead of the Au side. The excitation light from the backside can reach the Au grating without traveling through the sample liquid so that the unwanted attenuation of the illumination light by the sample can be avoided. The excitation light is diffracted by the grating, and the diffracted light couples to free electrons on the gold surface as SPR. Since SPR excites free electrons on the Au, they are detected as photocurrent at the Schottky junction at the Au/n-Si interface. In this study, we compared the current responses by the backside illumination method with changing the refractive index of sample using air and pure water. Depending on the change of the sample, peaks appeared at different angles in the currents response curve. We verified that the proposing device can discriminate sample species on the Au, and can perform as an SPR sensor.
Evaluating the utility of FEC with reliable multicast (2005)

Forward error correction (FEC) has been proposed as a technique for implementing efficient reliable multicast (RM). However, FEC incurs costs in encode/decode delay and implementation complexity. How much benefit is provided relative to these costs and how dependent is the benefit on the specific RM protocol? In this paper, we evaluate the benefits of FEC for RM, considering both proactive and reactive use with three RM recovery techniques: duplicate avoidance, limited scope multicast and subcast. Our simulation-based results indicate that FEC provides little benefit for an efficient RM protocol like OTERS and introduces extra delay for multi-point streaming data applications.
Functional Particulated Ionic Liquid-Based Silica Microcapsules (2017)

A method for the preparation of functional silica microcapsules containing 1-butyl-3-methylimidazolium hexafluorophosphate (BMIm[PF6]) is described. This method is based on emulsification of ionic liquid in water, and interfacial polycondensation of tetraethoxysilane (TEOS) and 3-aminopropyltrimethoxysilane (APTMS) using the sol-gel technique. The microcapsules were characterized by scanning electron microscopy, transition electron microscopy, thermal gravimetric analysis, infrared and solid state NMR. The resulted material was utilized efficiently in the Knoevenagel condensation.
A 1000+ Channel Bionic Communication System (2006)

The wireless electronic nervous system interface known as the Functional Electrical Stimulation-Battery Powered bion® System is being developed at the Alfred Mann Foundation. It contains a real-time propagated wave micro-powered multichannel communication system [1]. This system is designed to send bi-directional messages between an external Master Controller Unit (MCU), and each one of a group of injectable stimulator-sensor battery powered bion® implants (BPB). The system is capable of communicating in each direction about 90 times per second using a structure of 850 time slots within a repeating 11 millisecond time window. The system's total Time Division Multiple Access (TDMA) communication capability is about 77,000 two-way communications per second on a single 5MHz wide radio channel. Each time slot can be used by one BPB, or shared alternately by two or more BPBs. Each bidirectional communication consists of a 15 data bit message sent from the MCU sequentially to each BPB and 10 data bit message sent sequentially from each BPB to the MCU. Redundancy bits are included to provide error detection and correction. This communication system is designed to draw only a few microamps from the 3.6 volt, 3.0 mAHr Lithium Ion (LiIon) battery contained in each BPB, and the majority of the communications circuitry is contained within a 1.4 × 5 mm integrated circuit.
Mode locking in solitary lasers (1991)

We present an analysis of passively mode-locked lasers in which pulse formation is dominated by the interplay between self-phase modulation and negative dispersion in separate cavity elements. Steady-state pulse parameters and stability issues are discussed. Stability in these solitary systems relies on some passive amplitude modulation, and the ultimate system performance is found to depend sensitively on the magnitude of amplitude modulation relative to that of phase modulation.

Physiological trait networks enhance understanding of crop growth and water use in contrasting environments (2022)

Plant function arises from a complex network of structural and physiological traits. Explicit representation of these traits, as well as their connections with other biophysical processes, is required to advance our understanding of plant-soil-climate interactions. We used the Terrestrial Regional Ecosystem Exchange Simulator (TREES) to evaluate physiological trait networks in maize. Net primary productivity (NPP) and grain yield were simulated across five contrasting climate scenarios. Simulations achieving high NPP and grain yield in high precipitation environments featured trait networks conferring high water use strategies: deep roots, high stomatal conductance at low water potential ("risky" stomatal regulation), high xylem hydraulic conductivity and high maximal leaf area index. In contrast, high NPP and grain yield was achieved in dry environments with low late-season precipitation via water conserving trait networks: deep roots, high embolism resistance and low stomatal conductance at low leaf water potential ("conservative" stomatal regulation). We suggest that our approach, which allows for the simultaneous evaluation of physiological traits, soil characteristics and their interactions (i.e., networks), has potential to improve our understanding of crop performance in different environments. In contrast, evaluating single traits in isolation of other coordinated traits does not appear to be an effective strategy for predicting plant performance.
Comparison of Saliency-Based Sensorless Control Techniques for AC Machines (2004)

This paper analyzes saliency-based sensorless control methods for AC machines. The paper focuses on three different methods, which utilize the following signals: negative-sequence carrier-signal current, zero-sequence carrier-signal voltage, and pulse width-modulation-switching zero-sequence voltage. Applicability of these methods for both rotor position estimation (tracking of rotor-position-dependent saliencies) and flux position estimation (tracking of flux-dependent saliencies) is studied for each method, as well as aspects of their implementation.
Multiple-pulse methods of1H N.M.R. imaging of solids: second-averaging (1990)

Abstract Multiple-pulse cycles composed of short (approximately 2–4 μs) gradient pulses intercalated between solid echoes are examined to find useful approaches to solid-state imaging. The usefulness of a cycle is judged on how well it fulfils requirements that the dipolar terms in the Magnus expansion of the average Hamiltonian of the cycle vanish to zeroth order for finite radio-frequency pulse lengths, and to first order in a delta-function pulse approximation; that all important first-order dipolar cross-terms also vanish; and that chemical-shift evolution is suppressed. For imaging in solids, we demonstrate a phase-shifted version of the MREV-8 sequence with gradient pulses of alternating polarity applied in the long windows. The addition of phase shifts to certain pulses eliminates resonance offset and chemical-shift interactions via ‘second-averaging’, while the gradient is unaffected by this averaging since it is applied along the axis of second averaging. An image is shown of a poly(methyl methacrylate) phantom with resolution of approximately 100 μm for a 6·4 mm diameter sample. Methods are suggested for further increasing the resolution by a factor of four to six.
