FracBots: Overview and Energy Consumption Analysis (2019)

Abstract Fracture Robots (FracBots) prototype has been successfully designed, developed, fabricated and tested in the laboratory. They are magnetic induction (MI)-based wireless sensor nodes that have the inter-node wireless communication, sensing and localization estimation capabilities. FracBots are miniature devices that can operate as wireless underground sensor networks (WUSNs) inside hydraulic fractures to collect and communicate important data and generate real-time mapping. The energy source of the FracBots is a major challenge since the operational environment is the hydraulic fractures which impose a restriction on the size that doesn't allow enough space for the battery. In addition, the capability to extract the energy from a designate source is another key-role feature that has to be a function of the FracBots. In this regard, energy consumption analysis and evaluation has been done to ensure that all the FracBots have the required energy to work properly during the operation inside the hydraulic fractures. The electronic design of the FracBots must be highly efficient and capable of dramatically reducing power consumption. Thus, FracBots design is composed of ultra-low power electronic chips that enable a switch among an active mode, a deep sleep mode and a shutdown mode with automatic wake-up features (Low Power Modes (LPMs). Also, it includes an energy management unit that harvests surplus power stemming from the base station. This feature reduces the power consumption and ensure continuous operation. Based on our energy model and electronic design, deep analysis of the harvested and consumed energy is conducted in a laboratory testbed. Results of this study show the capability of the FracBots to harvest the required energy to operate and perform all the communications and sensing functionalities. Using ultra-low power electronic chips based on ferromagnetic technology (FRAM) and energy management unit reduce the power consumption of the FracBots by 50% at least.

The asymmetric synthesis of (–)-epibatidine 1, employing as the key step the asymmetric protonation of the achiral lithum enolate of cyclohexanone derivative 5 with chiral β-hydroxy sulfoxide 3b, is described.
Role of CD26 for CD4 memory T cell function and activation. (1996)

CD26 is a 110 kDa T cell activation antigen and has been shown to have DPPIV enzyme activity which cleaves amino-terminal dipeptides with either L-proline or L-alanine at the penultimate position. Recent studies showed that CD26 plays an integral role in T cell activation. A partial explanation of the mechanism of CD26 mediated T cell signaling appears to be its association with CD45 tyrosine phosphatase, which may be importance in T cell activation and signal transduction. In addition, we showed that CD26 is a receptor for adenosine deaminase (ADA). Moreover, ADA on the cell surface is involved in an important immunoregulatory mechanism by which released ADA binds to cell surface CD26 and this complex is capable of reducing the local concentration of adenosine. Thus, CD26 is a multifunctional molecule controlling many key aspects of lymphocyte function.
Platform switching as a means to achieving implant esthetics. (2005)

This article discusses the literature related to the dynamics that are in effect when an implant is placed in bone. Osseous and soft tissue changes can result subsequent to implant placement. These changes will determine the esthetic outcome. A technique will be presented to limit both osseous and soft tissue changes, thereby creating a predictable esthetic result.
Oral L-arginine supplementation in cystic fibrosis patients: a placebo-controlled study (2005)

Exhaled nitric oxide (eNO) is decreased in cystic fibrosis (CF). The effect of oral L-arginine, the precursor of enzymatic nitric oxide (NO) formation, on airway NO in patients with CF was studied. In a pilot study, oral L-arginine was given in a single dose of 200 mg x kg(-1) body weight to eight healthy controls and eight CF patients. Subsequently, the same L-arginine dose was given to 10 patients with CF (five females) t.i.d. for 6 weeks in a randomised double-blind placebo-controlled crossover study. A single dose of oral L-arginine resulted in a 5.5-fold increase of L-arginine in plasma and a 1.3-fold increase of L-arginine in sputum after 2 h. Maximum eNO, within 3 h of L-arginine intake, increased significantly in both CF patients (5.4+/-2.1 ppb versus 8.3+/-3.5 ppb) and controls (18.0+/-8.1 ppb versus 26.4+/-12.3 ppb). Supplementation of L-arginine for 6 weeks resulted in a sustained increase in eNO compared to placebo (9.7+/-5.7 ppb versus 6.3+/-3.1 ppb). An effect of L-arginine supplementation on forced expiratory volume in one second was not observed. These data indicate that airway nitric oxide formation in cystic fibrosis patients can be augmented with oral L-arginine supplementation.

Higher HPA activity, as reflected by increased plasma cortisol levels, is associated with more rapid disease progression in subjects with Alzheimer-type dementia.
Pt/PZT/n-SrTiO<sub>3</sub> Ferroelectric Memory Diode (1996)

We fabricated a new nonvolatile ferroelectric memory, which consists of vertical metal-ferroelectric- semiconductor diodes. Our diode has a simpler structure than an Ferroelectric Random Access Memory (FRAM) cell, and operates at a lower voltage than Metal Ferroelectric Semiconductor Field Effect Transistors (MFS-FETs) or conventional flash memories. We demonstrated the memory operation using a Pt/PZT/n- SrTiO 3 diode in this work. We deposited (001)-oriented PZT on (100) 0.5 wt% Nb doped n-type SrTiO 3 substrate using a laser ablation technique. The diodes had a hysteresis loop in their capacitance-voltage characteristics due to ferroelectric polarization in the PZT layer. Their current-voltage curves were Schottky-diode-like and also had a hysteresis loop due to the ferroelectric remanent polarization. We confirmed correct nonvolatile and nondestructive memory readout operation. The write voltages were -5 V to write a logic “0” and above 2.5 V to write a logic “1”. The read voltage was 0.8 V.
Enhancing the field of view limitation of Visible Light Communication-based platoon (2014)

Visible Light Communication (VLC) technology have recently been suggested as efficient supportive technology for platooning applications over short inter-vehicle distances. Though, ensuring the continuity of Line-of-Sight (LOS) of any optical-based applications is one of the most complex scenarios for an autonomous vehicle control, and still remains as an open challenge for Intelligent Transformation Systems (ITS). Exchanging information about the relative directional position of each member of the platoon, together with front and rear facing directions of each vehicle, can be very useful data for building a smooth geometrical-based compensation method, which results in ensuring that any increase in both incidence and irradiance optical angles will never exceed the Field of View (FOV) limitations and regardless of the trajectory shape. This paper propose a tracking alike compensation method of four vehicles equipped with positioning and VLC systems. We have simulated different scenarios related to different trajectories and compensation angles limits. The simulation results show that trajectories influence on the optical incidence and irradiance angles can be compensated efficiently and without deploying any tracking method.
Chlorinated C1 and C2 hydrocarbons in the marine environment (1975)

Abstract A range of chlorinated hydrocarbons derived from C1 and C2 hydrocarbons is manufactured industrially. They are used as intermediates for further chemical manufacture and also outside the chemical industry as solvents or carriers. In the latter category losses in use are eventually dispersed to the environment. The distribution of some of these compounds, including chloroform, carbon tetrachloride, trichloroethylene, perchloroethylene and trichloroethane, in the environment (air, water and marine sediments) has been investigated and the results are presented. The concentrations found have been compared with acute toxicity levels to fish and other aquatic organisms, ascertained by laboratory bioassay. The occurrence of the compounds has been determined in a number of marine organisms, especially those at higher trophic levels, and the accumulation of some of them has been investigated in the laboratory. Chemical and microbial degradation processes have been studied in the laboratory to help determine the course of their removal from the aqueous and aerial environment, and the half lives of some of the compounds have been estimated. It is concluded that these compounds are not persistent in the environment, and that there is no significant bioaccumulation in marine food chains.

How to mesh up Ewald sums. II. An accurate error estimate for the particle–particle–particle-mesh algorithm (1998)

We construct an accurate estimate for the root mean square force error of the particle–particle–particle mesh (P3M) algorithm by extending a single particle pair error measure which has been given by Hockney and Eastwood. We also derive an easy to use analytic approximation to the error formula. This allows a straightforward and precise determination of the optimal splitting parameter (as a function of system specifications and P3M parameters) and hence knowledge of the force accuracy prior to the actual simulation. The high quality of the estimate is demonstrated in several examples.
Frequency of Mycobacterium tuberculosis-specific CD8+ T-cells in the course of anti-tuberculosis treatment (2015)

Anti-tuberculosis drug treatment is known to affect the number, phenotype, and effector functionality of antigen-specific T-cells. In order to objectively gauge Mycobacterium tuberculosis (MTB)-specific CD8+ T-cells at the single-cell level, we developed soluble major histocompatibility complex (MHC) class I multimers/peptide multimers, which allow analysis of antigen-specific T-cells without ex vivo manipulation or functional tests. We constructed 38 MHC class I multimers covering some of the most frequent MHC class I alleles (HLA-A*02:01, A*24:02, A*30:01, A*30:02, A*68:01, B*58:01, and C*07:01) pertinent to a South African or Zambian population, and presenting the following MTB-derived peptides: the early expressed secreted antigens TB10.4 (Rv0288), Ag85B (Rv1886c), and ESAT-6 (Rv3875), as well as intracellular enzymes, i.e., glycosyltransferase 1 (Rv2957), glycosyltransferase 2 (Rv2958c), and cyclopropane fatty acid synthase (Rv0447c). Anti-TB treatment appeared to impact on the frequency of multimer-positive CD8+ T-cells, with a general decrease after 6 months of therapy. Also, a reduction in the total central memory CD8+ T-cell frequencies, as well as the antigen-specific compartment in CD45RA-CCR7+ T-cells was observed. We discuss our findings on the basis of differential dynamics of MTB-specific T-cell frequencies, impact of MTB antigen load on T-cell phenotype, and antigen-specific T-cell responses in tuberculosis.
Neighbor-Aided Localization in Vehicular Networks (2017)

We address the problem of localization in vehicular ad hoc networks. Our goal is to leverage vehicle communications and smartphone sensors to improve the overall localization performance. Assuming vehicles are equipped with the IEEE 802.11p wireless interfaces, we employ a two-stage Bayesian filter to track the vehicle's position: an unscented Kalman filter for heading estimation using smartphone inertial sensors, and a particle filter that fuses vehicle-to-vehicle signal strength measurements received from mobile anchors whose positions are uncertain, with velocity, GPS position, and map information. Our model leads to a robust localization system and is able to provide useful position information even in the absence of GPS data. We evaluate the algorithm performance using real-world measurements collected from four communicating vehicles in an urban scenario, and considering different combinations of location information sources.
Cloud Federation Management and Beyond: Requirements, Relevant Standards, and Gaps (2016)

In cloud computing, "hybrid cloud" and "community cloud" are established jargon. These concepts, however, actually entail federation, that is, the ability to securely share compute resources. Cloud federation has been investigated at all levels of the system stack-infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS). To better understand how to accomplish secure cloud federation, the author identifies six fundamental federation requirements, six deployment models, examines relevant existing standards, and discusses areas where further work needs to be done on best practices, tooling, and standards. The author notes that federation isn't specific to on-demand cloud resources and can be used to manage arbitrary services at any level in the system stack for a wide spectrum of application domains. Hence, federation has far-reaching implications for the scale and scope of cloud-based, and bare-metal-based, collaborations.

Thermoluminescence and radiophotoluminescence from Eu-and Sm-doped CaSO4 (1984)

X-or W irradiation of Eu and Sm-doped CaSO4, produces a partial conversion from RE2+ to RE2+. Sm2+, Eu2+, and Eu3+ can be detected using radiophotoluminescence (RPL) and could be utilised for dosimetry. Preliminary measurements show that the minimum RPL detectable exposures using Eu and Sm doped phosphors are (155 ± 12) and (116 ± 10) μCkg−1 after X-irradiation and (12 ± 6) mJcm−2 and (12 ± 6) J cm−2 after UV irradiation, respectively. Rare earth dopant mixtures such as Dy: Eu could be used for combined RPL/TL dosimetry. Die Röntgen-oder UV-Bestrahlung von Eu-und Sm-dotiertem CaSO4, erzeugt eine teilweise Umwandlung von RE2+ zu RE2+. Sm2+, Eu2+ und Eu2+ können durch Radiophotolumineszenz (RPL) nachgewiesen werden und konnten zur Dosimetrie verwendet werden. Erste Messungen zeigen, dass als niedrigste RPL Bestrahlungen von (155 ± 12) bzw. (116 ± 14) μC kg−1 durch X-Strahlen und (12 ± 6) mJ cm−2 bzw. (12 ± 6) J cm−2 durch UV, für Eu bzw. Sm dotiertes Phosphor nachweisbar sind. Mit Seltenen Erden dotierte Mischungen, wie Dy: Eu, könnten für kombinierte RPL/TL-Dosimetrie verwendet werden.
Speed scaling on parallel processors (2007)

In this paper we investigate algorithmic instruments leading to low powerconsumption in computing devices. While previous work on energy-efficient algorithms has mostly focused on single processor environments, in this paper we investigate multi-processor settings. We study the basic problem of scheduling a set of jobs, each specified by a release time, a deadline and a processing volume, on variable speed processors so as to minimize the total energy consumption. We first settle the complexity of speed scaling with unit size jobs. More specifically, we devise a polynomial time algorithm for agreeable deadlines and prove NP-hardness results for arbitrary release dates and deadlines. For the latter setting we also develop a polynomial time algorithm achieving a constant factor approximation guarantee that is independent of the number of processors. Additionally, we study speed scaling of jobs with arbitrary processing requirements and, again, develop constant factor approximation algorithms. We finally transform our offline algorithms into constant competitive online strategies.
Intravascular Ultrasound–Guided Vena Cava Filter Placement (1999)

Intraluminal IVC interrogation using IVUS is ideally suited for the proper deployment of an IVC filter. The deployment of IVC filters under IVUS has the potential to further simplify an established therapy for deep venous thrombosis and pulmonary embolism.
Inverse relationship of CD8+CD11+ suppressor T cells with human immunodeficiency virus (HIV)-specific cellular cytotoxicity and natural killer cell activity in HIV infection. (1991)

Profiles of CD8+CD11+ T suppressor cells, human immunodeficiency virus (HIV)-env-specific cytotoxic T-lymphocyte (CTL) activities, and natural killer (NK) cell activity were studied in 12 asymptomatic untreated HIV-infected patients. These patients were followed for 4-7 months. NK activity, HIV-env-specific CTL activities mediated by CD4+, CD8+ T cells and CD8+CD11+ T-suppressor cell number remained stable in seven patients during the study period. Alternatively, NK and HIV-specific CTL activities decreased and CD8+CD11+ cell number increased in five patients whose CD4+ T-cell number fell, and in four of these five patients serum p24 antigen level increased, and they developed minor clinical signs of disease progression during the study period. CD8+CD11+ cells are present in higher percentage (10-45% of peripheral blood mononuclear cells) in these HIV-infected patients as compared to those in normal individuals (3-5%). Our results suggest that CD8+CD11+ cells, NK, and HIV-specific cytotoxic activities may be helpful in monitoring prognosis of HIV infection. These observations also suggest that CD8+CD11+ cells may play an important role in the failure of host immune defences against HIV.
Influence of halo implant on leakage current and sheet resistance of ultrashallow p-n junctions (2007)

Sheet resistance and leakage current density of spike rapid thermal processed, millisecond flash annealed, and chemical vapor deposition (CVD) grown ultrashallow junctions (USJs) are compared with the contactless junction photovoltage technique for measurement of sheet resistance and leakage current (RsL) and four-point probe (4PP) techniques. A significant leakage current increase for USJs formed in halo-implanted profiles is explained by high electron and hole recombination generation in the near-surface end-of-range damaged layer enhanced by trap-assisted tunneling. The reduced thermal budget of millisecond annealing allows junction formation with reduced dopant diffusion and lower sheet resistance. However, when strong halo doping is employed, there is a significant increase in junction leakage current relative to that for junctions formed by spike annealing. This rise in leakage current can be reduced by annealing the halo implants before implanting the USJ or by lowering the halo implant dose. USJs grown with CVD demonstrate low leakage current due to localization of recombination centers at the edge of the depletion layer where recombination (generation) is low. This study demonstrates the importance of characterizing USJs formed in halo profile using the contactless RsL technique and highlights the limitations of contact probes, such as four-point probes, for characterization of advanced ultralarge scale integrated junctions.
P‐9: Metallic Nanowires Film as Transparent Conducting Layer in TFT‐LCDs (2008)

Abstract In this study, an innovative metallic nanowires (M‐NW) film was prepared by solution‐based method and was employed as transparent conducting layer in TFT‐LCD as replacement to ITO. The transparency and surface resistivity of the M‐NW film are 92% and 30Ω/□, respectively. In addition, a 4.1″ diagonal QVGA AM‐LCD with M‐NW film has been successfully developed.
FeN/Ta multilayers: magnetic properties and application to magnetic recording heads (1997)

Magnetic recording performance of inductive heads with hybrid top-pole structures consisting of thin sputtered FeN/Ta multilayers and thick electroplated NiFe was studied. Conventional 42-turn, 4-layer thin-film inductive heads were used and emphasis was placed on writability. Heads with hybrid top-displayed structures showed improved overwrite and nonlinear transition shift performance compared with NiFe-only heads.

Effects of Obesity on Substrate Utilization during Exercise (2002)

During moderate exercise, obese sedentary men have increased rates of fatty-acid oxidation from nonplasma sources and reduced rates of CHO oxidation, particularly muscle glycogen, compared with lean sedentary men.
Stereochemical course of the reaction catalyzed by the cyclic GMP phosphodiesterase from retinal rod outer segments. (1988)

The stereochemical course of hydrolysis catalyzed by the cyclic GMP phosphodiesterase from bovine retinal rod outer segments was determined. The Sp diastereomer of guanosine 3',5'-cyclic monophosphorothioate was hydrolyzed by cyclic GMP phosphodiesterase in H2(18)O to give [16O,18O]guanosine 5'-monophosphorothioate. This isotopomer was reacted with diphenyl phosphorochloridate to form the two diastereomers of P1-(5'-guanosyl) P2-(diphenyl) 1-thiodiphosphate. The 31P NMR spectrum of this mixture of diastereomers was identical to that obtained from [16O,18O]guanosine 5'-monophosphorothioate resulting from the hydrolysis of the Rp diastereomer of guanosine 5'-p-nitrophenyl phosphorothioate by snake venom phosphodiesterase. This finding indicates that the 18O is bridging in the Rp diastereomer of the P1-(5'-guanosyl) P2-(diphenyl) 1-thiodiphosphate and nonbridging in the Sp diastereomer. As the snake venom phosphodiesterase reaction is known to proceed with retention of configuration, it follows that hydrolysis by retinal rod cyclic GMP phosphodiesterase proceeds with inversion of configuration at the phosphorus atom.
