Water‐based inorganic/polymer hybrid particles prepared via a multiple miniemulsion process (2011)

Abstract A universal method for the synthesis of water‐based inorganic–polymer hybrid particles was developed in which no organic solvent is required. To demonstrate the versatility of this process, zinc phosphate, calcium carbonate, and barium sulfate were chosen as different pigment examples which additionally can be utilized for functional coating applications. Furthermore, a complex polymeric composition based on epoxy–acrylic–styrene was chosen to illustrate the versatility from a soft matter point of view. The overall synthesis process was carried out by coemulsification of two inverse miniemulsions, containing two precursors, surrounded with a polymerizable continuous phase. This was then transferred to a direct miniemulsion by addition to a surfactant solution and subsequent homogenization followed by radical polymerization of the vinylic monomers. To our knowledge, this is the first work where a polymerizable continuous phase has been used in an inverse miniemulsion formation followed by transfer to a direct miniemulsion, followed by polymerization, so that the result is a water‐based dispersion. The resultant dispersion was characterized by dynamic light scattering; the particles were investigated via transmission electron microscopy with in situ determination of crystallinity using electron diffraction. Elemental analysis was also performed for the particles and the polymerized miniemulsions using X‐ray fluorescence and inductively coupled plasma‐optical emission spectroscopy, respectively. © 2011 Wiley Periodicals, Inc.

Towards Self-Organized Location Privacy in Mobile Networks (2008)

Abstract—Pervasive communications bring along new privacy challenges, fueled by the capability of mobile devices to communicate with, and thus “sniff on”, each other directly. We design a new mechanism to achieve location privacy in these forthcoming mobile networks, whereby mobile nodes collect the pseudonyms of the nodes they encounter to generate their own privacy cloaks. Thus, privacy emerges from the mobile network and users gain control over the disclosure of their locations. We call this new paradigm self-organized location privacy. In addition, we investigate, using graph theory, the optimality of different cloak constructions. Finally, we evaluate with simulations the efficiency of self-organized location privacy in various network topologies. We show that peer-to-peer wireless communications and mobility help in the establishment of self-organized location privacy in mobile networks. I.
Regional variation of tibialis anterior tendon mechanics is lost following denervation (2006)

Denervation or inactivity is known to decrease the mass and alter the phenotype of muscle. The mechanical response of tendon to inactivity that has been determined experimentally differs from what is reported by patients. We investigated the hypothesis that this difference was the result of artifacts of the testing process and did not represent what occurred in vivo. To test this hypothesis, a novel approach was used to determine the mechanical properties of the tibialis anterior (TA) tendon by optically measuring the end-to-end mechanical strains as well as the local strains at specific regions of excised TA tendon units. When the end-to-end strain of normal TA tendon is determined, stress-strain response curves show considerably more extensibility than when strain is measured across only the midsection of the tendon (mid-tendon). The strain experienced by the region close to the muscle (muscle tendon) is five times greater than the strain in either the mid-tendon or near the bone (bone-tendon). Five weeks of denervation decreased muscle mass by 67%; increased tendon mass by 10%; and changed the entire shape of the nonlinear response curve, including a loss in regional variation in strain, a 3.9-fold increase in end-to-end tangent modulus, and a 70% reduction in the toe region, as a result of a drastic reduction of the extensibility in the muscle-tendon region. The stress-strain response in the mid-tendon region of a normal TA tendon is therefore not indicative of its overall ability to deform in vivo as it transmits forces from muscle to bone.
18 F-Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography Enables the Detection of Recurrent Same-Site Deep Vein Thrombosis by Illuminating Recently Formed, Neutrophil-Rich Thrombus (2014)

Noninvasive FDG-PET/CT identifies neutrophil-dependent thrombus inflammation in murine DVT, and demonstrates a time-dependent signal decrease in both murine and clinical DVT. FDG-PET/CT may offer a molecular imaging strategy to accurately diagnose recurrent DVT.
Multipurpose optimization of camera position by modeling image noise in camera for robot vision (2012)

Autonomous robots have been used in the manufacturing sector worldwide. However, they cannot be used in random or unknown environments because most of them are controlled by only sequence controls. Two cameras are used as vision sensors that can recognize the outside environment to solve this problem. We know that the positions of the two cameras affect the camera calibration accuracies. In this research, we aim at improving the camera calibration accuracies and propose a multipurpose optimization method of the cameras' positions. First of all, we examine the influences of the two cameras' positions for the calibration accuracies. In addition, we try to determine the optimal camera position from a simulation based on the image noise models obtained through experimentation. After that, we verify the effectiveness of the optimal camera position by conducting a discrimination experiment. As a result, we can model the image noises of two cameras mathematically and determine the optimal camera position. The discrimination accuracies are more than 0.99 and we prove that the proposed method is effective.

Sustainable ammonia production through process synthesis and global optimization (2018)

Current ammonia production technologies have a significant carbon footprint. In this study, we present a process synthesis and global optimization framework to discover the efficient utilization of renewable resources in ammonia production. Competing technologies are incorporated in a process superstructure where biomass, wind, and solar routes are compared with the natural gas‐based reference case. A deterministic global optimization‐based branch‐and‐bound algorithm is used to solve the resulting large‐scale nonconvex mixed‐integer nonlinear programming problem (MINLP). Case studies for Texas, California, and Iowa are conducted to examine the effects of different feedstock prices and availabilities. Results indicate that profitability of ammonia production is highly sensitive to feedstock and electricity prices, as well as greenhouse gas (GHG) restrictions. Under strict 75% GHG reductions, biomass to ammonia route is found to be competitive with natural gas route, whereas wind and solar to ammonia routes require further improvement to compete with those two routes. © 2018 American Institute of Chemical Engineers AIChE J , 65: e16498 2019
A Low-Power 40 Gbit/s Receiver Circuit Based on Full-Swing CMOS-Style Clocking (2007)

We describe circuit techniques for a 40 Gbit/s CMOS CDR circuit in 65 nm CMOS-SOI technology, which mostly uses a full-swing CMOS circuit style to minimize power and area. The quarter rate receiver uses a phase-programmable PLL (P-PLL) architecture for clock generation and phase tracking, and implements a high-speed sampler based on CMOS SenseAmp latches. The circuit uses 0.03mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> of chip area, and consumes 72m\V of power at 40 Gbps data rate. We describe in detail the implementation of several crucial components, i.e. the ring VCO, which was optimized for high-speed operation, and the sampling and demultiplexing stage.
Convergent Tree-Reweighted Message Passing for Energy Minimization (2006)

Algorithms for discrete energy minimization are of fundamental importance in computer vision. In this paper, we focus on the recent technique proposed by Wainwright et al. [33]--tree-reweighted max-product message passing (TRW). It was inspired by the problem of maximizing a lower bound on the energy. However, the algorithm is not guaranteed to increase this bound--it may actually go down. In addition, TRW does not always converge. We develop a modification of this algorithm which we call sequential tree-reweighted message passing. Its main property is that the bound is guaranteed not to decrease. We also give a weak tree agreement condition which characterizes local maxima of the bound with respect to TRW algorithms. We prove that our algorithm has a limit point that achieves weak tree agreement. Finally, we show that, our algorithm requires half as much memory as traditional message passing approaches. Experimental results demonstrate that on certain synthetic and real problems, our algorithm outperforms both the ordinary belief propagation and tree-reweighted algorithm in [33]. In addition, on stereo problems with Potts interactions, we obtain a lower energy than graph cuts.
Research of accommodative microfluctuations caused by visual fatigue based on liquid crystal and laser displays (2014)

Different levels of visual fatigue in the human eye depend on different color-formation methods and image quality. This paper uses the high-frequency component of the spectral power of accommodative microfluctuations as a major objective indicator for analyzing the effects of visual fatigue based on various displays, such as color-formation displays and 3D displays. Also, a questionnaire is used as a subjective indicator. The results are that 3D videos cause greater visual fatigue than 2D videos (p<0.001), the shutter-type 3D display causes visual fatigue more than the polarized type (p=0.012), the display of the time-sharing method causes greater visual fatigue than the spatial-formation method (p=0.008), and there is no significance between various light source modules of displays (p=0.162). In general, people with normal color discrimination have more visual fatigue than those with good color discrimination (p<0.001). Therefore, this paper uses the high-frequency component of accommodative microfluctuations to evaluate the physiological stress or strain by overexerting the visual system, and can compare the level of visual fatigue between various displays.

This paper proposes a novel low-complexity layered division multiplexing (LDM) transmitter and receiver structures for next generation terrestrial broadcasting systems. The proposed LDM system not only has low complexity because it shares the OFDM-related chain, but also provides significant performance gain (4 to 6 dB) compared to traditional time division multiplexing (TDM) system.

Abstract 4338: Advanced neoplasia detection in colorectal cancer screening using multiple stool DNA markers and haemoglobin (2016)

Abstract Purpose of the study: Molecular tests have the potential to improve current non-invasive faecal immunochemical test (FIT) screening for colorectal cancer (CRC) and advanced precancerous lesions. We examined the performance of a panel of faecal DNA (sDNA) markers and FIT in archival samples from an invitational CRC screening population. Methods: Whole stool samples were prospectively collected from individuals participating an invitational primary colonoscopy-screening program (COCOS trial). Only participants that provided stool, performed FIT (OC-Sensor) and underwent colonoscopy were selected. The sDNA panel included quantitative molecular assays for KRAS mutations and for aberrant NDRG4 and BMP3 methylation. The performance of the sDNA plus FIT panel was compared to the FIT results alone, by Receiver Operator Characteristic (ROC) analyses. Results: A total of 1047 individuals (51% male) with a median age of 60 years (range 50-75) were included, of which 7 (0.7%) had colorectal cancer and 104 (9.9%) had advanced precancerous lesions (advanced adenomas or sessile serrated polyps ≥ 1 cm). The combination of sDNA and FIT was more sensitive than FIT alone for detecting advanced precancerous lesions (49% (50/102) and 25% (26/102), respectively). Specificities among individuals with non-advanced or negative findings (controls) were 89% and 96% for sDNA and FIT testing, respectively. ROC analysis of CRC and advanced precancerous lesions compared to controls revealed an Area Under the Curve (AUC) of 0.75 for the sDNA plus FIT test, compared to 0.68 for FIT alone. At an equal specificity of 95%, advanced precancerous lesions were detected with a higher sensitivity by the sDNA plus FIT test compared to FIT alone (36% vs 28%, p = 0.08). Conclusions: In an invitational colorectal cancer screening cohort, combining stool DNA markers with FIT detected more advanced neoplasia than FIT alone, primarily due to detecting more advanced adenomas.

Theoretical investigation of functional responses of bio-molecular assembly networks (2023)

Cooperative protein-protein and protein-DNA interactions form programmable complex assemblies, often performing non-linear gene regulatory operations involved in signal transductions and cell fate determination. The apparent structure of those complex assemblies is very similar, but their functional response strongly depends on the topology of the protein-DNA interaction networks. Here, we demonstrate how the coordinated self-assembly creates gene regulatory network motifs that corroborate the existence of a precise functional response at the molecular level using thermodynamic and dynamic analyses. Our theoretical and Monte Carlo simulations show that a complex network of interactions can form a decision-making loop, such as feedback and feed-forward circuits, only by a few molecular mechanisms. We characterize each possible network of interactions by systematic variations of free energy parameters associated with the binding among biomolecules and DNA looping. We also find that the higher-order networks exhibit alternative steady states from the stochastic dynamics of each network. We capture this signature by calculating stochastic potentials and attributing their multi-stability features. We validate our findings against the Gal promoter system in yeast cells. Overall, we show that the network topology is vital in phenotype diversity in regulatory circuits.
Current Technologies and Recent Developments for Screening of HPV-Associated Cervical and Oropharyngeal Cancers (2016)

Mucosal infection by the human papillomavirus (HPV) is responsible for a growing number of malignancies, predominantly represented by cervical cancer and oropharyngeal squamous cell carcinoma. Because of the prevalence of the virus, persistence of infection, and long latency period, novel and low-cost methods are needed for effective population level screening and monitoring. We review established methods for screening of cervical and oral cancer as well as commercially-available techniques for detection of HPV DNA. We then describe the ongoing development of microfluidic nucleic acid-based biosensors to evaluate circulating host microRNAs that are produced in response to an oncogenic HPV infection. The goal is to develop an ideal screening platform that is low-cost, portable, and easy to use, with appropriate signal stability, sensitivity and specificity. Advances in technologies for sample lysis, pre-treatment and concentration, and multiplexed nucleic acid detection are provided. Continued development of these devices provides opportunities for cancer screening in low resource settings, for point-of-care diagnostics and self-screening, and for monitoring response to vaccination or surgical treatment.

Hydrogen Incorporation in Diamond: The Vacancy-Hydrogen Complex (2004)

We report the identification of the vacancy-hydrogen complex in single crystal diamond synthesized by chemical vapor deposition. The S=1 defect is observed by electron paramagnetic resonance in the negative charge state. The hydrogen atom is bonded to one of the carbon atoms neighboring the vacancy. Unlike the analogous defect in silicon, no symmetry lowering reconstruction occurs between the three remaining carbon dangling orbitals. The very small measured hydrogen hyperfine interaction is explained by dipolar coupling between the hydrogen and the unpaired electron probability density delocalized on the three equivalent carbon neighbors.
A Mechanism for Cooperative Demand-Side Management (2017)

Demand-side management (DSM) is an important theme in studies of the Smart Grid and offers the possibility of leveling power consumption with its attendant benefits of reducing capital expenses. This paper develops an algorithmic mechanism that reduces peak total power consumption and encourages prosocial behavior, such as expressing flexibility in one's power consumption and reporting preferences truthfully. The objective is to provide a tractable, budget-balanced mechanism that promotes truth-telling from households. The resulting mechanism is theoretically and empirically proven to be ex ante budget-balanced, weakly Pareto-efficient, and weakly Bayesian incentive-compatible. A simulation study verifies that the mechanism could largely reduce the computational complexity that the optimal allocation requires, while maintaining approximately the same performance. A user study with 20 subjects further shows the effectiveness of the mechanism in preventing participants from defecting and incentivizing them to reveal flexible preferences.
Fabrication of Fe2TiO5/TiO2 binary nanocomposite from natural ilmenite and their photocatalytic activity under solar energy (2021)

Heterogeneous photocatalysis is an attractive alternative route to enhance the degradation of environmental pollutants. In this work, we have fabricated Fe2TiO5/TiO2 binary nanocomposites using natural ilmenite via bottom up approach. Synthesized nanocomposites were characterized by X-ray diffractometry, X-ray fluorescence, transmission electron microscopy, Raman spectroscopy, diffuse reflectance UV–Visible spectroscopy, scanning electron microscopy, and X-ray photoelectron spectroscopy. These nanoparticles are in the range of 40–70 ​nm and are of type I heterostructure with a band gap of 2.02 ​eV. They are sensitive to visible light and show higher photocatalytic activity under direct solar energy. Photocatalytic activity of Fe2TiO5/TiO2 was assessed using a model textile dye, methylene blue. Over a period of 2 ​h, 76% of methylene blue was photodegraded at a rate of 0.0084 min−1 in the presence of Fe2TiO5/TiO2.
