An efficient scheme for MTC overload control based on signaling message compression (2013)

Whilst Machine Type Communication (MTC) represents an important business opportunity for mobile operators, mobile operators fear the congestion that could come with the deployment of billions/trillions of MTC devices. In this paper, we present a new mechanism that anticipates system overload due to MTC signaling messages in 3GPP networks. This mechanism proactively avoids system congestion by compacting the signaling message content for a group of MTC devices sharing redundant Information Elements (IE) by creating a profile ID for this group. Furthermore, along with this solution, we propose a dynamic grouping solution, which groups MTC devices with common subscription features in order to control the MTC signaling traffic when the network is overloaded. Simulation results show that compared to the Access Class Baring (ACB) mechanism, introduced by 3GPP, our proposed solution can avoid system overload without dropping MTC signaling messages, which is highly beneficial for MTC applications requiring service reliability.
The Moduli Space of (1,11)-Polarized Abelian Surfaces is Unirational (2001)

We prove that the moduli space $\cal A$ 11 lev of <$>(1,11)-polarized Abelian surfaces with level structure of canonical type is birational to Klein's cubic hypersurface in P 4 . Therefore, $\cal A$ 11 lev is unirational but not rational, and there are no Γ 11 -cusp forms of weight 3. The same methods also provide an easy proof of the rationality of $\cal A$ 9 lev .
L-arginine abrogates salt-sensitive hypertension in Dahl/Rapp rats. (1991)

This study examined the contribution of nitric oxide (NO) to the susceptibility or resistance to the hypertensive effects of high sodium chloride (8.0% NaCl) intake in young Dahl/Rapp salt-sensitive (SS/Jr) and salt-resistant (SR/Jr) rats. Using NG-monomethyl-L-arginine (L-NMMA) as a probe for NO production in vivo, we found that increasing dietary sodium chloride increased NO activity in salt-resistant rats, but not in salt-sensitive rats. Exogenous L-arginine, the substrate for NO synthesis, decreased blood pressure to normotensive levels in salt-sensitive rats made hypertensive for 2 wk from 8.0% NaCl chow. D-arginine had no effect on blood pressure of these rats and L-arginine did not change blood pressure of salt-resistant rats. Intraperitoneal injections of L-arginine and its precursor, L-citrulline, and oral L-arginine, but not D-arginine, prevented the increase in blood pressure in salt-sensitive rats on the high salt chow over 2 wk of observation. In contrast, L-arginine did not alter the development of hypertension in spontaneously hypertensive rats. Mean urinary cGMP levels were higher in salt-sensitive rats on oral L-arginine than salt-sensitive rats on D-arginine. Infusion of L-NMMA acutely decreased, whereas intravenous L-arginine rapidly increased, urinary cGMP in both groups. L-arginine and L-citrulline increased production of NO and prevented salt-sensitive hypertension in Dahl/Rapp rats.
Mapping internet sensors with probe response attacks (2005)

Abstract Internet sensor networks, including honeypots and loganalysis centers such as the SANS Internet Storm Center, are used as a tool to detect malicious Internet traf-fic. For maximum effectiveness, such networks publish public reports without disclosing sensor locations, so thatthe Internet community can take steps to counteract the malicious traffic. Maintaining sensor anonymity is crit-ical because if the set of sensors is known, a malicious attacker could avoid the sensors entirely or could over-whelm the sensors with errant data.

Adaptive Accessible AR/VR Systems (2021)

Augmented, virtual and mixed reality technologies offer new ways of interacting with digital media. However, such technologies are not well explored for people with different ranges of abilities beyond a few specific navigation and gaming applications. While new standardization activities are investigating accessibility issues with existing AR/VR systems, commercial systems are still confined to specialized hardware and software limiting their widespread adoption among people with disabilities as well as seniors. This proposal takes a novel approach by exploring the application of user model-based personalization for AR/VR systems to improve accessibility. The workshop will be organized by experienced researchers in the field of human computer interaction, robotics control, assistive technology, and AR/VR systems, and will consist of peer reviewed papers and hands-on demonstrations. Keynote speeches and demonstrations will cover latest accessibility research at Microsoft, Google, Verizon and leading universities.
The General Stress Sigma Factor ςS ofEscherichia coli Is Induced during Diauxic Shift from Glucose to Lactose (1998)

The general stress sigma factor ςS (RpoS) ofEscherichia coli is strongly induced in response to glucose starvation. This increase in the cellular ςS level is due to stabilization of ςS, which under non-stress conditions is subject to rapid proteolysis. In the present study, it is demonstrated that ςS is also induced during the diauxic shift from glucose to lactose, i.e., under conditions of glucose exhaustion in the presence of another, less-preferred carbon source that eventually gets utilized. This ςS induction, which is due to stabilization, is transient and precedes the induction of β-galactosidase. In parallel, ςS-dependent genes are transiently activated, as was shown here for osmY. Although ςS can mediate transcription of lacZ in vitro, ςS does not contribute to the induction of β-galactosidase during the diauxic lag phase. Rather, the induction of ςS and the general stress response during the diauxic shift plays the role of a rapidly activated emergency system, which is shut off again as soon as the cells are able to cope with the stress situation by utilizing a more specific and more economical system.
Modeling and Performance of Gas Turbine Cycles with Various Means of Blade Cooling (2001)

A method for simulating the cooled gas turbine is demonstrated. Based on equations and other knowledge found in the literature, a first-law thermodynamic, non-dimensional model is established and implemented in the equation-solving, programmable software IPSEpro. Increasing the water vapor or carbon dioxide contents of the gas turbine hot gas is found not to have an impact on the Stanton number, which is employed for the modeling of the heat transfer to the blade. The model is validated using experimental data from an industrial gas turbine and data found in the literature, and is found to give results easily in concordance with the case with which it is matched. Based on the validation, a reference gas turbine is established and employed for various cycle calculations. First, it is shown how gas turbine efficiency can increase with decreased coolant temperature and with a decrease in the ratio of specific heats between hot gas and coolant. Simple-cycle simulations are done to illustrate the impact of coolant pre-cooling, cooling with humid air and cooling with steam. Due to its high specific heat, steam is shown to have the best capacity for cycle performance enhancement. For the single-pressure combined cycle, it is shown how steam for cooling of the first gas turbine vane can be flashed from the water leaving the economiser in a split stream boiler. This is found to give a considerable increase in cycle thermal efficiency (more than three percentage points), but the concept needs to be further evaluated in order to establish whether it is technically feasible. For the studies of the HAT cycle, the role of the compressor modeling is emphasized. For a compressor with a given geometry, extracting a reduced amount of air for cooling will give an increase in the pressure ratio, which will have a positive impact on the HAT cycle thermal efficiency, but it will also, in practice, lead to the surge margin being approached. For cooling with humid air, there will be no significant increase in the HAT cycle thermal efficiency if the compressor ratio is maintained constant. Designing gas turbine cycles with a high thermal efficiency is not a goal in itself; also good economic performance is important. The impact of cooled blades for the profitability of the gas-turbine based power plant is illustrated briefly, with focus on heat resistance versus materials cost and on compressor washing intervals.
Interfacial Electron Transfer between the Photoexcited Porphyrin Molecule and TiO<sub>2</sub> Nanoparticles:  Effect of Catecholate Binding (2006)

Interfacial electron transfer (ET) dynamics of 5,10,15-trisphenyl-20-(3,4-dihydroxybenzene) porphyrin (TPP-cat) adsorbed on TiO2 nanoparticles has been studied by femtosecond transient absorption spectroscopy in the visible and near-IR region exciting at 400 and 800 nm. TPP-cat molecule forms a charge transfer (CT) complex with TiO2 nanoparticles through the catechol moiety with the formation of a five-membered ring. Optical absorption measurements have shown that the Q-band of TPP-cat interacts strongly with TiO2 due to chelation; however, the Soret band is affected very little. Optical absorption measurements indicate that the catechol moiety also interacts with TiO2 nanoparticles showing the characteristic band of pure catechol-TiO2 charge transfer (CT) in the visible region. Electron injection has been confirmed by monitoring the cation radical, instant bleach, and injected electron in the conduction band of TiO2 nanoparticles. Electron injection time has been measured to be < 100 fs and recombination kinetics has been best fitted with a multiexponential function, where the majority of the injected electrons come back to the parent cation radical with a time constant of approximately 800 fs for both excitation wavelengths. However, the reaction channel for the electron injection process has been found to be different for both wavelengths. Excitation at 800 nm, found to populate the CT state of the Q-band, and from the photoexcited CT state electron injection into the conduction band, takes place through diffusion. On the other hand, with excitation at 400 nm, a complicated reaction channel takes place. Excitation with 400 nm light excites both the CT band of Cat-TiO2 and also the Soret band of TPP-cat. We have discussed the reaction path in the TPP-cat/TiO2 system after exciting with both 400 and 800 nm laser light. We have also compared ET dynamics by exciting at both wavelengths.
Toxicity of ZnO Nanoparticles to Macrophages Due to Cell Uptake and Intracellular Release of Zinc Ions (2014)

Although the ZnO nanoparticles (NPs) have been widely used in research and industry, their health risks are only concerned very recently. In this paper, attention is paid to elucidate the toxic effects and intrinsic mechanism of ZnO NPs to RAW 246.7 macrophage cells. The ZnO NPs from industry additives had a diameter of ~37 nm in a dry state and aggregated to submicron size in cell culture medium with slightly negative surface charge. Influences of ZnO NPs on cell toxicity and functions were then studied in terms of cell viability, mitochondrial membrane potential (MMP), total and released lactate dehydrogenase (LDH) activity, intracellular level of reactive oxygen species (ROS) and Zn2+ concentration. The ZnO NPs induced elevation of intracellular Zn2+ concentration, leading to the over generation of intracellular ROS, leakage of plasma membrane, dysfunction of mitochondria, and cell death. The solubility of ZnO NPs was found largely enhanced in acidic environment (pH 5.5), compared to physiological condition (pH 7.2). Inhibition of cell uptake of ZnO NPs would largely reduce the cytotoxicity. These results demonstrate that the cell uptake, intracellular dissolution and thereafter release of Zn2+ are the intrinsic reasons for the high toxicity of ZnO NPs.
Droplet spraying of heavy metal fluoride glass for optical waveguide fabrication (1989)

We have demonstrated a novel technique for rapid thermal quenching of heavy metal fluoride glass melts for use in optical fiber preform fabrication. Molten fluoride glass droplets were sprayed from a gas-atomizing nozzle system. Amorphous ZrF4-BaF2-LaF3-AlF3-NaF particles were obtained with very high quenching rates (∼1200 K/min) compared to bulk cast glass samples.
A graph-partitioning-based approach for multi-layer constrained via minimization (1998)

We propose a new layer assignment approach for the klayer Constrained Via Minimization (CVM) problem. We transform the problem into a constrained k-way graph partitioning one. Practicfl issues such as pin-out constraint, over-the-cd constraint, and overlapping between wire segments of the same net, have d been taken into consideration. We propose a motied simdated-anneahng program for the problem. A set of large routing restits generated by a commercial three-layer router has been used to test the effectiveness of the program. Up to 70% reduction of vias has been observed. Assuming an additional fourth layer is avdable, more reduction is achieved. This work is the first to demonstrate the feasibfity of via minimization for practical-sized mtiti-layer layout. It is &o app~cable to future design with more layers.
Automated Java GUI Modeling for Model-Based Testing Purposes (2011)

Advanced methods and tools for GUI software development allow a rapid and iterative process of prototyping and usability testing. Unfortunately, even with the support of test automation tools, testing of GUI software requires a lot of manual work, especially when the application under test is changing rapidly. In this paper we present an improved method and tool support for automated test modeling of Java GUI applications for model-based testing (MBT) purposes. The implemented GUI Driver tool generates structural models combined with a GUI state model presenting the behavior of the GUI application that is executed and observed automatically. The GUI Driver tool is combined with an open source MBT tool to form a tool chain to support automated testing of Java GUI applications. The models generated by the GUI Driver are used to generate test sequences with MBT tool, and the test sequences are then executed with the GUI Driver to generate a test report.
Layered Lithium Insertion Material of LiCo1/3Ni1/3Mn1/3O2 for Lithium-Ion Batteries (2001)

Abstract Layered LiCo1/3Ni1/3Mn1/3O2 was prepared by a solid state reaction at 1000 °C in air and examined in nonaqueous lithium cells. LiCo1/3Ni1/3Mn1/3O2 showed a rechargeable capacity of 150 mAh g−1 in 3.5–4.2 V or 200 mAh g−1 in 3.5–5.0 V. Operating voltage of Li / LiCo1/3Ni1/3Mn1/3O2 was by 0.2–0.25 V lower than that of a cell with LiCoO2 or LiMn2O4 and by 0.15–0.3 V higher than that with LiNiO2 or LiCo1/2Ni1/2O2 due to a complex solid solution mechanism.

This work demonstrates the feasibility of estimating hepatic perfusion parameters using interrupted data acquired during sequential breathholds.
The chemistry of terpenes. Part I. Hydrogenation of the pinenes and the carenes (1966)

Conditions have been established for the catalytic hydrogenation of (+)-α-pinene to give over 98% of (+)-cis-pinane. Modification of the reaction conditions leads to the formation of over 50%trans-pinane. Conditions have also been established for the hydrogenation of (+)-car-3-ene giving over 98% of (–)-cis-carane. Trans-carane has not yet been obtained, but under appropriate conditions (+)-car-3-ene affords quantitative yields of 1,1,4-trimethylcycloheptane, suggested intermediates in the formation of which have been isolated, including (+)-car-2-ene.
Vinblastine, Ifosfamide, Gallium Nitrate, and Filgrastim in Platinum- and Paclitaxel-Resistant Ovarian Cancer (1998)

The authors performed a phase II trial of the VIG regimen (vinblastine, ifosfamide, and gallium nitrate) in patients who had advanced ovarian cancer who were refractory to cisplatin and/or carboplatin and whose disease had progressed after paclitaxel-based therapy. This was a heavily pretreated population, with five patients having received two to three prior chemotherapy regimens and six patients having received more than six prior chemotherapy regimens, with an average of 21 therapy cycles per patient. Fourteen patients were treated with vinblastine, 0.08 mg/kg intravenously on days 1 and 2; ifosfamide, 900 mg/m2 intravenously on days 1 through 5 with standard mesna uroprotection; and gallium nitrate administered as a continuous intravenous infusion at 225 mg/m2 per 24 hours x 120 hours. Granulocyte colony-stimulating factor (G-CSF) was administered subcutaneously at 5 microg/kg/day beginning on day 7 until day 13. Five of 14 patients achieved a partial response for an overall response rate of 36% (95% confidence interval, 14%-68%). The median response duration was 14 weeks. Toxicity was primarily hematologic, with anemia and leukopenia being most significant. There were no treatment-related deaths. Further evaluation of this regimen in a less heavily pretreated population is warranted.
Numeric Investigation of Brain Tumor Influence on the Current Distributions During Transcranial Direct Current Stimulation (2015)

This study constructed a series of high-resolution realistic human-head models with brain tumors, and numerically investigated the influence of brain tumor's location and grade on the current distributions, under different electrode montages during tDCS. The threshold area and the peak current density were also derived and analyzed in the region of interest. The simulation result showed that it is safe to apply tDCS on the patients with brain tumors to treat their neuropsychiatric conditions and cancer pain caused by the tumor; although considerable changes of the current distributions are induced by the presence of a brain tumor. In addition, several observations on the global and local influences of tumor grade and possible edema have been made as well. These findings should be helpful for researchers and clinical doctors to treat patients with brain tumors. This study is also the first numerical study to fill in the gap of tDCS applications on the patients with brain tumors.
The importance of a functional trehalose biosynthetic pathway for the life of yeasts and fungi (2003)

The view of the role of trehalose in yeast has changed in the last few years. For a long time considered a reserve carbohydrate, it gained new importance when its function in the acquisition of thermotolerance was demonstrated. More recently the cellular processes in which the trehalose biosynthetic pathway has been implicated range from the control of glycolysis to sporulation and infectivity by certain fungal pathogens. There is now enough experimental evidence to conclude that trehalose 6-phosphate, an intermediate of trehalose biosynthesis, is an important metabolic regulator in such different organisms as yeasts or plants. Its inhibition of hexokinase plays a key role in the control of the glycolytic flux in Saccharomyces cerevisiae but other, likely important, sites of action are still unknown. We present examples of the phenotypes produced by mutations in the two steps of the trehalose biosynthetic pathway in different yeasts and fungi, and whenever possible examine the molecular explanations advanced to interpret them.
Intraarticular apatite crystal deposition as a predictor of erosive osteoarthritis of the fingers. (1994)

Two patients are described who presented with a chronic effusion with calcium containing particles, considered as apatite, in one finger joint. After a followup of several years, these joints presented erosive changes on radiographs, which raises the question of the pathogenic role of apatite crystals.
Compressive coded random access for massive MTC traffic in 5G systems (2015)

Massive MTC support is an important future market segment, but not yet efficiently supported in cellular systems. In this paper we follow-up on recent concepts combining advanced MAC protocols with Compressed Sensing (CS) based multiuser detection. Specifically, we introduce a concept for sparse joint activity, channel and data detection in the context of the Coded ALOHA (FDMA) protocol. We will argue that a simple sparse activity and data detection is not sufficient (as many papers do) because control resources are in the order of the data. In addition, we will improve on the performance of such protocols in terms of the reduction of resources required for the user activity, channel estimation and data detection. We will mathematically analyze the system accordingly and provide expressions for the capture probabilities of the underlying sparse multiuser detector. Finally, we will provide CS algorithms for the joint estimation scheme and evaluate its performance.
Voltage-controlled inversion of tunnel magnetoresistance in epitaxial nickel/graphene/MgO/cobalt junctions (2014)

We report on the fabrication and characterization of vertical spin-valve structures using a thick epitaxial MgO barrier as spacer layer and a graphene-passivated Ni film as bottom ferromagnetic electrode. The devices show robust and scalable tunnel magnetoresistance, with several changes of sign upon varying the applied bias voltage. These findings are explained by a model of phonon-assisted transport mechanisms that relies on the peculiarity of the band structure and spin density of states at the hybrid graphene|Ni interface.
A 5 GHz CMOS low-noise amplifier with inductive ESD protection exceeding 3 kV HBM (2004)

This work presents a 5 GHz LNA with on-chip ESD-protection provided by an integrated inductor. The circuit is implemented in a standard 0.18 /spl mu/m CMOS technology. The LNA is matched at both input and output. It achieves a power gain of 20 dB with a noise figure of 3.5 dB at a power consumption of only 15 mW including the output buffer. The protection level complies with the class II HBM standard of 2 kV.
Epigenetic Regulation of Thy-1 by Histone Deacetylase Inhibitor in Rat Lung Fibroblasts (2010)

Thy-1 is a cell surface glycoprotein present on normal lung fibroblasts but absent from the fibroblastic foci of idiopathic pulmonary fibrosis. Thy-1 correlates inversely with fibrogenic phenotypic characteristics and functions as a "fibrosis suppressor." Promoter region hypermethylation can silence Thy-1 expression in fibroblastic foci, suggesting that epigenetic regulation is important in programming the fibrotic phenotype. We examined whether histone modifications are important in regulating Thy-1 expression in lung fibroblasts. Treatment with the histone deacetylase inhibitor trichostatin A (TSA) restored Thy-1 expression in Thy-1(-) cells in a time-dependent and concentration-dependent fashion and was associated with enrichment of histone acetylation. Chromatin immunoprecipitation demonstrated Thy-1 depletion of trimethylated H3K27 after 24 hours of TSA treatment, concurrent with enrichment of trimethylated H3K4 and acetylated H4. Bisulfite sequencing of the Thy-1 promoter region revealed demethylation of the previously hypermethylated CpG sites after treatment with TSA. Although Thy-1 was hypermethylated in Thy-1(-) lung fibroblasts, we observed that Thy-1(-) cells have lower global DNA methylation compared with Thy-1(+) lung fibroblasts, which was partially reversed by TSA treatment. TSA treatment up-regulates total methyltransferase activity in these cells. Our data indicate that Thy-1 silencing is regulated by histone modifications in addition to promoter hypermethylation in lung fibroblasts. Additionally, our findings indicate that alteration of histone modifications alters DNA methylation. Understanding the molecular hierarchy of events with respect to reactivation of transcription and reversal of histone modification will be critical to understand and modify the regulated expression of Thy-1, a tumor-supressor and fibrosis-suppressor gene.
