Wireless sensor network: Water distribution monitoring system (2008)

Historically, wireless sensor networks have mainly addressed military applications. However, in recent years, many civilian applications, such as managing inventory, monitoring product quality and monitoring disaster zones have emerged. Various technical issues, such as power consumption, radio propagation models, routing protocols, sensors etc need to be considered for different applications. In this paper, we propose a particular application for wireless sensor networks, specifically a water distribution network monitoring system. We propose a possible communication model for the water distribution monitoring network, and describe our channel measurement approach for the determination of an appropriate path-loss model. The accuracy of the proposed measurement approach has been confirmed using the flat earth two-ray model [1].

Attenuation by Tetrahydrocurcumin of Adiposity and Hepatic Steatosis in Mice with High-Fat-Diet-Induced Obesity (2018)

Diet-induced obesity is strongly associated with nonalcoholic fatty-liver disease (NAFLD) and insulin resistance. We aimed to investigate the in vivo therapeutic value of tetrahydrocurcumin (THC) intervention in high-fat-diet (HFD)-induced obesity and hepatic steatosis. C57BL/6 mice were fed an HFD for 10 weeks, and then they received 20 or 100 mg/kg THC along with the HFD for another 10 weeks. Mice fed an HFD for 20 weeks experienced obesity, hepatic steatosis, hyperlipidemia, and insulin resistance. Tetrahydrocurcumin (THC) intervention for 10 weeks significantly reduced adiposity (epididymal-fat weights of 6.6 ± 0.4 g for the HFD-only group and 5.3 ± 0.8 and 5.6 ± 0.7 g for the HFD with 20 mg/kg THC and HFD with 100 mg/kg THC groups, respectively; p < 0.05) via downregulation of adipogenic factors. Inflammatory macrophage infiltration and polarization were decreased by THC in mouse epididymal adipose tissues. In the liver, THC markedly alleviated steatosis by approximately 28-37% ( p < 0.05) via the downregulation of lipogenesis, the activation of AMP-activated protein kinase (AMPK), and the increase of fatty acid oxidation. Elevated blood glucose and insulin resistance were also improved by THC, which might be caused by regulation of the hepatic insulin signaling cascade, gene transcription involved in glucose metabolism, and reduced macrophage infiltration in the liver and adipose tissue. Our results demonstrated the beneficial effects of THC-mediated intervention against obesity and NAFLD as well as other metabolic syndromes, revealing a novel therapeutic use of THC in obese populations.
Hierarchical mobile IPv6 based architecture for heterogeneous wireless networks interworking (2011)

The demand for accessing services while on the move, at any place and time, has lead to the current efforts towards integration of heterogeneous wireless networks, in particular UMTS, WiMAX and WLAN, as complementary systems. Integration can be performed at different levels: tight coupling and loose coupling. The paper presents the design and evaluation of a HMIPv6 based architecture for different wireless networks interworking. Our proposed architecture aims to solve the problems existing in present interworking solutions, such as congestion in the UMTS core network.

The authors report the experimental realisation of a 10 cm long 1.55 µm Er3+-doped DFB fibre laser, with a permanent phase shift incorporated into the fibre grating during writing. Output powers of 1 mW and an optical linewidth of 13 kHz are observed.
Rational Approaches to Inhibition of Human Osteoclast Cathepsin K and Treatment of Osteoporosis (1999)

Novel, potent and selective human osteoclast cathepsin K inhibitors have been designed based on knowledge derived from the crystal structure of papain bound to a tripeptide aldehyde. Cathepsin K is a thiol protease belonging to the papain superfamily. Unlike previously known crystal structures of that family of enzymes in which ligands bind to the nonprime side of the active site, our papain structure shows the ligand in the prime direction. This observation and the identification of key interactions between the protein and the ligand inspired the design of a novel class of inhibitors spanning both sides of the active site. The crystal structure of the first member of this class bound to cathepsin K confirmed our design hypothesis. Inhibitors of cathepsin K are potential drugs for the treatment of osteoporosis.
Influence of the charge pumping effect on an integrated solid-state image sensor using MOST switches (1973)

The charge pumping in image sensors with MOST switches is simulated experimentally and discussed. It is found that photodiode potential is changed with no illumination, that photoelectric characteristics are degraded, and that a storage mode operation cannot be achieved. A desirable treatment available to diminish this effect is proposed.
Diet and exercise as a management strategy for symptoms of polycystic ovary syndrome (PCOS): the views of women in the community with PCOS. (2020)

Abstract Background The international clinical practice guidelines for PCOS emphasize diet and exercise as first-line management of clinical signs and symptoms. This study aimed to describe the patterns, perceptions and experiences of lifestyle interventions for women in the community with PCOS. Method An electronic survey of 493 members of two PCOS consumer support groups described women’s types and patterns of diet and exercise, experiences and perceptions of effectiveness. Women were recruited from the Polycystic Ovary Association of Australia (POSAA) and from the Facebook group, PCOS University Research Group. Associations between participants perceptions of effectiveness, and diet types and exercise patterns were assessed using logistic regression. Response bias for the POSAA group was assessed with a continuum of resistance model. Results 91% of POSAA members aged 16-50 years responded to the survey. Nearly all women reported adjusting their dietary and exercise practices with the aim to improve their health and/or PCOS (82% and 73% respectively), however less than 13% reported achievement of health goals (12.2% and 8.1% respectively). Low carbohydrate, high protein diets, and vigorous activity were associated with self-perceived effectiveness (r.0.16, p&lt;0.01; r.0.15 p&lt;0.01 and r.0.2 p&lt;0.01 respectively). Barriers for lifestyle interventions included psychosocial factors. Response bias was not assessed for the Facebook group, however self-reported PCOS aligned with prevalence of clinical phenotypes and suggests results are generalizable to clinical populations of women with PCOS, who are responsible for self-directing and administering lifestyle interventions to manage their PCOS. Conclusions Perceptions of effectiveness for lifestyle interventions by women with PCOS may be complicated by a lack of rigorous evidence. The strength of recommendations in clinical practice guidelines may be enhanced by clinical trials investigating flexible and feasible lifestyle interventions for women in the community with PCOS.
Template-based video coding with opacity representation (1997)

We describe an image coding scheme based on multiple templates for interactive audio-visual (AN) database retrieval. The image sequence to be coded consists of overlapping image planes with opacity information and depth ordering. In this method, each image plane is independently encoded to a different bit stream where each video object sequence is reconstructed from representative frames (i.e., templates) by global and local deformations. Owing to this coding scheme, the following new functionalities are supported: identification and manipulation of two-dimensional (2-D) video objects, selective decoding and browsing of visual contents, and very high compression efficiency. We have extended an MPEG1 coding software to an object-based coding software. Experimental results of the proposed scheme prove the above advantages.
Bessel-Butterworth transitional filters (2014)

The paper considers a new class of polynomial filters with transfer functions calculated via a recurrent relationship. The procedure starts choosing two kernel algebraic ratios u <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0</sub> (s) = 1 and u <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sub> (s) = 1 + 1 / s where s is the complex variable. Further ratios are obtained via the recurrent relationship u <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">n+1</sub> (s) = [(2n + d) / s]u <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">n</sub> (s) + u <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">n-1</sub> (s) where n ≥ 1 and d is a parameter. The numerators of these ratios are taken as denominator polynomials for filter transfer functions. When d = 1 these polynomials are coinciding with the Bessel polynomials. The corresponding filters (or Bessel filters) have a very small step-response overshoot (less than 1%). When d ≠ 1 (the paper considers the range of 0 ≤ d ≤ 1), and is decreasing, the step-response overshoot is increasing. For d = 0 it becomes about 10% as in Butterworth filters. The proposed filters are transitional between Bessel and Butterworth and called here as BeBut filters.

1,2,3,4,6-Penta-O-galloylglucose within Galla Chinensis Inhibits Human LDH-A and Attenuates Cell Proliferation in MDA-MB-231 Breast Cancer Cells (2015)

A characteristic feature of aggressive malignancy is the overexpression of lactic acid dehydrogenase- (LDH-) A, concomitant to pericellular accumulation of lactate. In a recent high-throughput screening, we identified Rhus chinensis (Mill.) gallnut (RCG) (also known as Galla Chinensis) extract as a potent (IC50 < 1 µg/mL) inhibitor of human LDH-A (hLDH-A). In this study, through bioactivity guided fractionation of the crude extract, the data demonstrate that penta-1,2,3,4,6-O-galloyl-β-D-glucose (PGG) was a primary constituent responsible for hLDH-A inhibition, present at ~9.95 ± 0.34% dry weight. Theoretical molecular docking studies of hLDH-A indicate that PGG acts through competitive binding at the NADH cofactor site, effects confirmed by functional enzyme studies where the IC50 = 27.32 nM was reversed with increasing concentration of NADH. Moreover, we confirm protein expression of hLDH-A in MDA-231 human breast carcinoma cells and show that PGG was toxic (LC50 = 94.18 µM), parallel to attenuated lactic acid production (IC50 = 97.81 µM). In a 72-hour cell proliferation assay, PGG was found to be a potent cytostatic agent with ability to halt cell division (IC50 = 1.2 µM) relative to paclitaxel (IC50 < 100 nM). In summary, these findings demonstrate that PGG is a potent hLDH-A inhibitor with significant capacity to halt proliferation of human breast cancer cells.
Altered Marginal Zone B Cell Selection in the Absence of IκBNS (2017)

Marginal zone (MZ) B cells reside in the splenic MZ and play important roles in T cell-independent humoral immune responses against blood-borne pathogens. IκBNS-deficient <i>bumble</i> mice exhibit a severe reduction in the MZ B compartment but regain an MZ B population with age and, thus, represent a valuable model to examine the biology of MZ B cells. In this article, we characterized the MZ B cell defect in further detail and investigated the nature of the B cells that appear in the MZ of aged <i>bumble</i> mice. Flow cytometry analysis of the splenic transitional B cell subsets demonstrated that MZ B cell development was blocked at the transitional-1 to transitional-2-MZ precursor stage in the absence of functional IκBNS. Immunohistochemical analysis of spleen sections from wild-type and <i>bumble</i> mice revealed no alteration in the cellular MZ microenvironment, and analysis of bone marrow chimeras indicated that the MZ B cell development defect in <i>bumble</i> mice was B cell intrinsic. Further, we demonstrate that the B cells that repopulate the MZ in aged <i>bumble</i> mice were distinct from age-matched wild-type MZ B cells. Specifically, the expression of surface markers characteristic for MZ B cells was altered and the L chain Igλ<sup>+</sup> repertoire was reduced in <i>bumble</i> mice. Finally, plasma cell differentiation of sorted LPS-stimulated MZ B cells was impaired, and aged <i>bumble</i> mice were unable to respond to NP-Ficoll immunization. These results demonstrate that IκBNS is required for an intact MZ B cell compartment in C57BL/6 mice.
Numerical and experimental investigations of large IC flip chip attach (2000)

Because flip chips can achieve high electrical interconnect speed, high density, and low profiles, a team from the Fraunhofer Institute for Reliability and Microintegration in Berlin and from Georgia Tech undertake a study examining the extreme limits of flip chip input/output (I/O) capabilities and physical dimensions. Their starting point is a SIA estimate of memory requirements, based on Moore's Law, for the year 2012. In order to study the limitations of flip chip technology the groups are working on both, advanced thermomechanical simulation and hands-on interconnection technology resulting in the design of four flip chips. They have the dimensions of 10/spl times/10 mm/sup 2/, 20/spl times/20 mm/sup 2/, 30/spl times/30 mm/sup 2/, and 40/spl times/40 mm/sup 2/. With these designs both, the simulation and the interconnection technology departments of Fraunhofer IZM start to evaluate the feasibility of flip chips beyond 20/spl times/20 mm/sup 2/.
Chemical Pretreatment and Microfiltration for Making Delipidized Whey Protein Concentrate (1995)

ABSTRACT Chemical pretreatment, microfiltration (MF) and ultrafiltration (UF) were applied to produce delipidized whey protein concentrates (WPC). Processes including both chemical pretreatment and MF resulted in WPC with &lt;0.5% lipids. Low‐pH UF and isoelectric point (PI) precipitation were more effective for lipid removal than chemical pretreatment by thermocalcic aggregation. Protein permeation ratios in MF processes were improved by UF preconcentration of whey. Protein permeation and flux were different between the two MF membranes used. Isoelectric point precipitation increased β‐Lg contents, but not α‐La, in the resulting WPC (B). Minor proteins exhibited lower concentrations in WPC B and MF WPC products.
Optimal Resource Allocation for NOMA-Enabled Cache Replacement and Content Delivery (2019)

In a content-delivery network, files’ popularity and users’ requests change fast. Conventional caching schemes, e.g., caching (re)placement once per day during the off-peak hours, may not capture the up-to-date popularity. In this case, the contents in caches have to be regularly updated to prevent information becoming outdated, and at the same time users’ requested files must be delivered. These two tasks are challenging in practical heavy-traffic and multi-user scenarios when the network resources are limited. In this paper, we apply non-orthogonal multiple access (NOMA) to facilitate concurrent caching replacement and content delivery in downlink transmission. We formulate a resource allocation problem to investigate how to efficiently push proactive files to the cache at the small base station and deliver the requested files to users. The resource-allocation problem is formulated as a mixed-integer exponential conic optimization problem. To enable a computationally-efficient optimal solution with finite convergence, we develop an iterative algorithm based on polyhedral outer approximation, where a polyhedral relaxation subproblem and a convex subproblem are constructed and iteratively solved to tighten the lower and upper bounds for the optimum, respectively. The numerical results demonstrate significant performance gains of the NOMA-enabled data transmission scheme in power and resource savings compared to the baseline scheme.
Evaluation of an Impact Spring-Coil-Magnet System with 3D-Printed Setup (2018)

For several energy harvesting applications impact generators are one approach of generating energy to perform wireless transmissions to notify about an event. The goal is to harvest enough energy for a notification of a BLE-Chip to notify about one impact. Therefore magnet coil systems are one common approach. There are many variances assemble different arrangements of magnet, coils and springs. With this report we give an overview to behavior of coil behaviors by transmission of magnets. Therefore a setup is built with a 3D-Printer to reduce constructional effort. This transmission behavior of several 4 mm N45 neodymium magnets with different coils (height from 1-10mm, 100-400 windings) and springs setups are giving an idea about the practical approach and some comparison about simulation and measurement is done.
Tunable Raman spectroscopy study of CVD and peapod-derived bundled and individual double-wall carbon nanotubes (2010)

We use 40 laser excitation energies to analyze the differences in the Raman spectra from chemical vapor deposition-derived double-wall carbon nanotube (CVD-DWNT) bundles, fullerene-derived DWNT bundles (C[subscript 60]-DWNTs), and individual fullerene-derived DWNTs with inner type-I and type-II semiconducting tubes paired with outer metallic tubes. For the radial breathing mode (RBM) of SWNTs, an experimental omegaRBM vs dt relationship of the form omegaRBM=A/dt+B is obtained for the inner tubes of DWNT bundles where the A and B constants are found to be close to those obtained by elasticity theory when modeling the elastic properties of graphite. A similar change in omegaRBM is observed for an inner type-II semiconducting (6,5) tube and a type-I (9,1) tube when inside various metallic outer tubes. The G-band frequency is observed to upshift when switching the laser resonance from DWNTs with semiconducting inner tubes to DWNTs with metallic inner tubes. Finally, we measure the G′ feature from C[subscript 60]-DWNTs and note a downshift in frequency with respect to that of CVD-DWNTs.
Nanomaterials and nanoparticles: Sources and toxicity (2008)

This review is written with the goal of informing public health concerns related to nanoscience, while raising awareness of nanomaterials toxicity among scientists and manufacturers handling them. We show that humans have always been exposed to nanoparticles and dust from natural sources and human activities, the recent development of industry and combustion-based engine transportation profoundly increasing anthropogenic nanoparticulate pollution. The key to understanding the toxicity of nanoparticles is that their minute size, smaller than cells and cellular organelles, allows them to penetrate these basic biological structures, disrupting their normal function. Among diseases associated with nanoparticles are asthma, bronchitis, lung cancer, neurodegenerative diseases (such as Parkinson`s and Alzheimer`s diseases), Crohn`s disease, colon cancer. Nanoparticles that enter the circulatory system are related to occurrence of arteriosclerosis, and blood clots, arrhythmia, heart diseases, and ultimately cardiac death. We show that possible adverse effects of nanoparticles on human health depend on individual factors such as genetics and existing disease, as well as exposure, and nanoparticle chemistry, size, shape, and agglomeration state. The faster we will understand their causes and mechanisms, the more likely we are to find cures for diseases associated with nanoparticle exposure. We foresee a future with better-informed, and hopefully more cautious manipulation of engineered nanomaterials, as well as the development of laws and policies for safely managing all aspects of nanomaterial manufacturing, industrial and commercial use, and recycling.
Natural co‐occurrence of Fusarium toxins and aflatoxin B1 in com for feed in North Vietnam (1995)

Natural occurrence of Fusarium mycotoxins (trichothecenes and fumonisins) and aflatoxin B1 (AFB1) were surveyed in 32 corn samples, harvested in 1993 and randomly sampled in 1994 in several districts of Hanoi, Vietnam. Corn samples were first milled into fine powder, extracted with methanol-water (3:1) and the crude extracts obtained from the same samples were used for the simultaneous analysis of the trichothecenes such as nivalenol (NIV), deoxynivalenol (DON), and T-2 toxin (T-2) by gas chromatography/mass spectrometry (GC/NS); fumonisins B1 (FB1), B2 (FB2), and B3 (FB3) by high-performance liquid chromatography (HPLC) with a flourescence detector; and AFB1 by and ELISA kit based on a monoclonal antibody. The data revealed that 14, 8, 4, 3, and 2 out of 15 corn kernel samples were positive for AFB1, FB1, FB2, FB3, and NIV with the average levels being 28, 1, 101, 276, 232, and 858 ppb, respectively, and neither DON nor T-2 were detected. As for the other 17 samples of corn powder, 13, 15, 12, 10, 4 and 2 were positive for AFB1, FB1, FB2, FB3, DON, and NIV with the average being 30, 780, 289, 176, 3, 170, and 1,365 ppb, respectively, and T-2 was not detected. Although their positive rates and levels fell in the ranges reported elsewhere, it was found for the first time that the Fusarium toxins (NIV, DON, and fumonisins) and an Aspergillus toxin (AFB1) were naturally co-contaminated in selected samples of corn produced in north Vietnam.

Algebraic approach to analysis of discrete-time polynomial systems (1999)

In this paper, we focus on the discrete-time polynomial systems and present the modified algorithms for testing observability and accessibility based on the methods by D. Nešić. Our method uses not only quantifier elimination but also Gröbner basis and real root counting techniques for decision problems needed in checking the properties and incorporates the strategy to improve efficiency in testing equivalence of ideals. Moreover, we show that invertibility of the systems can be checked by using Gröbner basis technique and hence backward accessibility and transitivity can be tested in the similar way in finite time step.
