Simulation and measurements of physical layer parameters for passive UHF RFID tags toward collision detection and canceling (2012)

Radio-Frequency IDentification (RFID) is anenabling and emergent technology. Nowadays it still remains several challenging research issues beforeits widespread implementation, especially in dense environment. One of the main problems that limit the efficiency of passive UHF RFID system is the collision between the tags. Current solutions are based on collision avoidance using Media Access Control (MAC) Protocols (e.g. Frame Slotted Aloha, Binary Tree algorithms), whichcan be time consuming process because when a collision is detected, the retransmission of RN16 frame is required and all the signals in the physical layer are discarded. This paper presentsan experimental and simulation study of physical layer parameters for passive UHF RFID tags. Physical characteristics of the backscatter tag's (Modulation type, signal encoding, datatransfert rate and power Tag activation) are used in order to detect collision. This preliminary work shows the influence of these parameters and their impact on the collision phenomenon.
Lungs exposed to nuclear catastrophe: one-year therapeutic programme in Chernobyl liquidators group. (1997)

The high prevalence of chronic respiratory problems in cleaning technicians (so-called "liquidators") of the destroyed reactor at Chernobyl and prolonged persistence of inhaled radioactive particles in their lungs suggested a substantial link between radioactive exposure and the diseases observed. Taking into account the importance of the problem, we started this study with the aim of establishing an effective and useful therapeutic program and assessing its efficacy during a one-year period of treatment. Chernobyl liquidators (n = 20) were screened by clinical history, physical examination, lung function test, chest radiograph, electrocardiogram, complete blood cell counts, serum chemistry, immunological blood tests, and complete BAL fluid investigation. One group of the patients (n = 10) underwent a special one-year treatment including polyvitamins, N-acetylcysteine, and therapeutic BAL every 3 months. The technique of therapeutic BAL has proven to be a promising and effective tool in the treatment of lung diseases induced by inhalation of radioactive particles.

Wear‐Resistant Nanoscale Silicon Carbide Tips for Scanning Probe Applications (2012)

Abstract The search for hard materials to extend the working life of sharp tools is an age‐old problem. In recent history, sharp tools must also often withstand high temperatures and harsh chemical environments. Nanotechnology extends this quest to tools such as scanning probe tips that must be sharp on the nanoscale, but still very physically robust. Unfortunately, this combination is inherently contradictory, as mechanically strong, chemically inert materials tend to be difficult to fabricate with nanoscale fidelity. Here a novel process is described, whereby the surfaces of pre‐existing, nanoscale Si tips are exposed to carbon ions and then annealed, to form a strong silicon carbide (SiC) layer. The nanoscale sharpness is largely preserved and the tips exhibit a wear resistance that is orders of magnitude greater than that of conventional silicon tips and at least 100‐fold higher than that of monolithic, SiO‐doped diamond‐like‐carbon (DLC) tips. The wear is well‐described by an atom‐by‐atom wear model, from which kinetic parameters are extracted that enable the prediction of the long‐time scale reliability of the tips.
Evaluating PE/PLA interfacial tension using ternary immiscible polymer blends (2021)

Abstract Blending with ethylene‐based flexible polymers such as polyethylene (PE) is one of the strategies to toughen poly(lactic acid) (PLA), an inherently brittle biodegradable plastic enjoying growing demands worldwide. Interfacial tension plays a crucial role in blend formulation. Yet several literature reports on the PE/PLA interfacial tension contradict each other, giving ~5 mN/m and ~11 mN/m. In this work, we demonstrate that the PE/PLA interfacial tension is at least 9 mN/m. We use a cocontinuous PE/polystyrene (PS)/PLA ternary blend. Scanning electron microscopy (SEM) revealed complete wetting morphology with PS phase separating PE and PLA phases in the ternary blend. In addition, the complete wetting behavior was maintained at a PS volume fraction as low as 3%. This morphology together with the Harkins equation, indicate that the PE/PLA interfacial tension is higher than 10.5 ± 1.4 mN/m at 180°C.
Low dose methylprednisolone prophylaxis to reduce inflammation during one‐lung ventilation (2008)

In a piglet model of one-lung ventilation, use of prophylactic methylprednisolone prior to collapse of the lung improves lung function and decreases systemic pro-inflammatory response. In addition, in the piglets who received methylprednisolone, there were reduced levels of inflammatory mediators in both the collapsed and ventilated lungs.
Towards Factory-Scale Edge Robotic Systems: Challenges and Research Directions (2022)

Mobile multi-robot systems are an integral component of highly automated factories of the future. Since mobile robots have limited on-board computing capability and battery capacity, there is increasing interest in exploring approaches that enable robots to effectively leverage wireless communications and Edge Computing solutions for perception, navigation, planning, coordination, and control. It is, however, a major challenge achieving precision, high-speed, co-ordinated actions between robots due to tight end-to-end latency, and safety requirements, especially while enabling time-sensitive data exchange over wireless networks and execution of computing workloads distributed across robots and the Edge system. The traditional approach of designing compute, communications, and control components in an Edge system as independent components, limits the capacity and scalability of computing and wireless resources and is therefore unsuitable to meet performance guarantees for energy and resource-efficient time-sensitive robotic applications. In this article, we discuss technical challenges in the context of two Edge Robotics use cases such as conveyer object pick-up and robot navigation, which are representative of time-critical control in IoT applications. We propose research directions grounded in an end-to-end system co-design paradigm and describe technology components such as virtualized robot functions, compute-communications-control co-design, Edge system co-simulation, safety and security aspects that are core to Edge Robotics. We also briefly outline future research directions that are necessary to pave the path toward factory-scale Edge Robotics systems.
Genetic differences accounting for evolution and pathogenicity of simian immunodeficiency virus from a sooty mangabey monkey after cross-species transmission to a pig-tailed macaque (1992)

We determined the nucleotide sequences of two related isolates of simian immunodeficiency virus from the sooty mangabey monkey (SIVsmm) that exhibit dramatic differences in virulence. These isolates are separated by one experimental cross-species transmission, from sooty mangabey to pig-tailed macaque. The parental virus (SIVsmm9), nonpathogenic in the original host (sooty mangabeys), causes a chronic AIDS-like disease in macaques. In contrast, the variant virus (SIVsmmPBj14) induces an acute lethal disease in various macaque species and is also pathogenic for sooty mangabeys. The combination of necessary and sufficient mutations that determined the acutely lethal phenotype on the SIVsmm9 genetic background is included within a maximal set of 57 point mutations, plus two insertions located in the long terminal repeat (22 bp spanning an NF-kappa B-like enhancer element) and in the surface envelope glycoprotein (5 amino acids). Comparisons of synonymous and nonsynonymous nucleotide substitutions in the genome of SIVsmm indicated that selective pressures, probably due to the host immune response, favored amino acid changes in the envelope. This immunoevolutionary mechanism could explain the increase in diversity and the apparition of new virulent phenotypes after cross-species transmission.
Myocardial protection during surgical ventricular restoration☆ (2006)

Cardioplegic delivery for protection is 'time dependent' (needing ischemic intervals) while beating nourishment is 'procedure dependent,' as continuous perfusion is provided throughout the procedure is suggested. The importance of maintaining high perfusion pressure is emphasized.
Role of platelets in maintenance of pulmonary vascular permeability to protein (1988)

We examined the role of platelets in maintenance of pulmonary vascular integrity by inducing thrombocytopenia in sheep using antiplatelet serum (APS). A causal relationship between thrombocytopenia and increase in pulmonary vascular permeability was established by platelet repletion using platelet-rich plasma (PRP). Sheep were chronically instrumented and lung lymph fistulas prepared to monitor pulmonary lymph flow (Qlym). A balloon catheter was positioned in the left atrium to assess pulmonary vascular permeability to protein after raising the left atrial pressure (Pla). Thrombocytopenia was maintained for 3 days by daily intramuscular APS injections. Platelet count decreased from 460,000 +/- 77,000 to 16,000 +/- 4,000 platelets/microliters, without significant changes in the leukocyte count and hematocrit. Studies were made in three groups: 1) control sheep having a normal platelet count; 2) thrombocytopenic sheep; and 3) PRP-infused thrombocytopenic sheep. Elevation in Pla in control sheep increased pulmonary transvascular protein clearance (CL) to 12.1 +/- 2.1 ml/h, whereas the same Pla elevation in thrombocytopenia increased CL to 24.1 +/- 4.0 ml/h, indicating an increase in pulmonary vascular permeability to protein in thrombocytopenic animals. Infusion of PRP restored normal permeability, since it prevented the increase in CL. In studies using cultured bovine pulmonary artery endothelial monolayers, transendothelial permeability of 125I-labeled albumin was reduced 50 and 95%, respectively, when 2.5 X 10(7) or 5 X 10(7) platelets were added onto endothelial monolayers. However, addition of 5 X 10(6) platelets or 5 X 10(7) red blood cells did not reduce endothelial monolayer albumin permeability.(ABSTRACT TRUNCATED AT 250 WORDS)
Grating Coupler Design for Reduced Back-Reflections (2017)

A grating coupler having asymmetric grating trenches for low back reflections is experimentally demonstrated. Conventional and asymmetric-trench grating couplers have been fabricated on a silicon nitride waveguide platform. Both grating couplers have fully etched trenches, which normally result in higher back reflections than shallow-etched trenches. For evaluating the back reflection characteristics, test structures based on a 3-dB multimode interference power splitter have been measured and the backreflection has been extracted from each grating coupler using an equivalent optical circuit. The designed grating coupler has no critical penalty (<;0.2 dB) in coupling efficiency and ~5 dB lower back reflections than a conventional grating coupler design. Using ray transfer matrix modeling, further improvements to the back reflection characteristics of the asymmetric grating coupler are expected.
A Host Interface to the DTM Network (2001)

DTM, dynamic synchronous transfer mode, is a new time division multiplexing technique for fiber networks currently being developed and implemented at the Royal Institute of Technology in Stockholm, Sweden. This paper describes the hardware and software aspects of the design of an SBus host interface to the DTM network for a Sun SPARCstation. The interface is based on a dual port memory residing on the interface card and accesible over the SBus from the host CPU. The host operating system allocates message buffers directly in this memory. The interface has hardware support for segmenting and reassembling packets to and from the data units of the DTM. The software part of the interface manages the shared memory and the virtual circuits provided by the DTM network.
Virtual Private LAN Services (VPLS) (2012)

Virtual Private LAN Services (VPLS) is a multipoint service, but unlike IP Virtual Private Networks (VPNs), it can transport non-IP traffic and leverages advantages of Ethernet. VPLS is also used within a service provider’s (SP) network to aggregate services for delivery to residential and enterprise customers. In VPLS, customers maintain complete control over their routing, since all the customer routers in the VPLS are part of the same subnet (LAN). Data plane of VPLS deals with frame encapsulation, classification, MAC address learning and aging, and forwarding is described in this chapter. VPLS control plane functions mainly autodiscovery and provisioning of PWs are accomplished with a single BGP update advertisement. In the autodiscovery, each PE discovers other PEs that are a part of a given VPLS instance via BGP. Data in a VPLS is only distributed to other nodes in that VPLS and not to any external agent or other VPLS. Controlled Vocabulary Terms ethernet networks; IEEE 802.11 Standards; local area networks
Lightweight Floating-Point Arithmetic: Case Study of Inverse Discrete Cosine Transform (2002)

To enable floating-point (FP) signal processing applications in low-power mobile devices, we propose lightweight floating-point arithmetic. It offers a wider range of precision/power/speed/area trade-offs, but is wrapped in forms that hide the complexity of the underlying implementations from both multimedia software designers and hardware designers. Libraries implemented in C++ and Verilog provide flexible and robust floating-point units with variable bit-width formats, multiple rounding modes and other features. This solution bridges the design gap between software and hardware, and accelerates the design cycle from algorithm to chip by avoiding the translation to fixed-point arithmetic. We demonstrate the effectiveness of the proposed scheme using the inverse discrete cosine transform (IDCT), in the context of video coding, as an example. Further, we implement lightweight floating-point IDCT into hardware and demonstrate the power and area reduction.
Toward a Materials Genome Approach for Ionic Liquids: Synthesis Guided by Ab Initio Property Maps (2014)

The Materials Genome Approach (MGA) aims to accelerate development of new materials by incorporating computational and data-driven approaches to reduce the cost of identification of optimal structures for a given application. Here, we use the MGA to guide the synthesis of triazolium-based ionic liquids (ILs). Our approach involves an IL property-mapping tool, which merges combinatorial structure enumeration, descriptor-based structure representation and sampling, and property prediction using molecular simulations. The simulated properties such as density, diffusivity, and gas solubility obtained for a selected set of representative ILs were used to build neural network models and map properties for all enumerated species. Herein, a family of ILs based on ca. 200,000 triazolium-based cations paired with the bis(trifluoromethanesulfonyl)amide anion was investigated using our MGA. Fourteen representative ILs spreading the entire range of predicted properties were subsequently synthesized and then characterized confirming the predicted density, diffusivity, and CO2 Henry's Law coefficient. Moreover, the property (CO2, CH4, and N2 solubility) trends associated with exchange of the bis(trifluoromethanesulfonyl)amide anion with one of 32 other anions were explored and quantified.
Acute 40 percent exchange‐transfusion with hemoglobin‐vesicles (HbV) suspended in recombinant human serum albumin solution: degradation of HbV and erythropoiesis in a rat spleen for 2 weeks (2006)

HbVs were phagocytized and degraded in RES, a physiological compartment for the degradation of RBCs, and the elevated erythropoietic activity resulted in the complete recovery of Hct within 7 days in the rat model.
X-ray photoemission core level determination of the GaSb/AlSb heterojunction valence-band discontinuity (1986)

The valence-band discontinuity ΔEv has been determined for the (100) GaSb/AlSb strained-layer heterojunction with a room-temperature lattice mismatch of 0.65%, using x-ray photoemission core level spectroscopy. For 30 Å epitaxial layers of AlSb grown on GaSb, the measured valence-band offset was ΔEv=0.40±0.15 eV. The reverse growth sequence consisting of a thin GaSb layer grown on an AlSb buffer exhibited the same valence-band offset, indicating that for the (100) oriented heterojunction ΔEv is not strongly affected by the growth sequence.
Myogenesis and MyoD Down-regulate Sp1 (1997)

Muscle cell differentiation caused a reduction of glucose transport, GLUT1 glucose transporter expression, and GLUT1 mRNA levels. A fragment of 2.1 kilobases of the rat GLUT1 gene linked to chloramphenicol acetyltransferase drove transcriptional activity in myoblasts, and differentiation caused a decrease in transcription. Transient transfection of 5' and 3' deletion constructs showed that the fragment -99/-33 of the GLUT1 gene drives transcriptional activity of the GLUT1 gene and participates in the reduced transcription after muscle differentiation. Electrophoretic mobility shift assays showed the binding of Sp1 protein to the fragment -102/-37 in the myoblast state but not in myotubes, and Sp1 was found to transactivate the GLUT1 promoter. Western blot analysis indicated that Sp1 was drastically down-regulated during myogenesis. Furthermore, the forced over-expression of MyoD in C3H10T1/2 cells mimicked the effects observed during myogenesis, Sp1 down-regulation and reduced transcriptional activity of the GLUT1 gene promoter. In all, these data suggest a regulatory model in which MyoD activation during myogenesis causes the down-regulation of Sp1, which contributes to the repression of GLUT1 gene transcription and, therefore, leads to the reduction in GLUT1 expression and glucose transport.
Metabolic disposition of14C-venlafaxine in mouse, rat, dog, rhesus monkey and man (1993)

1. The metabolic disposition of venlafaxine has been studied in mouse, rat, dog, rhesus monkey and man after oral doses (22, 22, 2, and 10 mg/kg, and 50 mg, respectively) of 14C-venlafaxine as the hydrochloride. 2. In all species, over 85% of the administered radioactivity was recovered in the urine within 72 h, indicating extensive absorption from the GI tract and renal excretion. 3. Venlafaxine was extensively metabolized, with only 13.0, 1.8, 7.9, 0.3 and 4.7% dose appearing as parent compound in urine of mouse, rat, dog, monkey and man, respectively. The metabolite profile varied significantly among species, but primary metabolic reactions were demethylations and the conjugation of phase I metabolites. Hydroxylation of the cyclohexyl ring also occurred in mouse, rat and monkey, and a cyclic product was formed in rat and monkey. Glucuronidation was the primary conjugation reaction, although sulphate conjugates were also detected in mouse urine. 4. While no metabolite constituted more than 20% dose in any species except man, the major urinary metabolites were: mouse, N,O-didesmethyl-venlafaxine glucuronide; rat, cis-1,4-dihydroxy-venlafaxine; dog, O-desmethyl-venlafaxine glucuronide; monkey, N,N,O-tridesmethyl-venlafaxine; and man, O-desmethyl-venlafaxine.

In Vivo Proliferation of Adoptively Transferred Tumor-Infiltrating Lymphocytes in Mice (1991)

The adoptive transfer of tumor-infiltrating lymphocytes (TILs) in conjunction with interleukin-2 (IL-2) administration can mediate a reduction in established pulmonary and hepatic metastases of a variety of murine tumors as well as in patients with metastatic melanoma. To characterize further the fate of adoptively transferred TILs, the uptake of the thymidine analog 5-[125I]iodo-2-deoxyuridine ([125I]UdR) into the DNA of dividing cells was used to study the in vivo proliferation and migration patterns of transferred TILs in C57BL/6N mice. Animals received 500 rad of total body irradiation prior to cell transfer to separate incorporation of radiolabel into endogenous lymphoid cells from that into transferred TILs. Mice were subsequently treated with i.v. injections of TILs or no cells followed by i.p. injections of Hanks' balanced salt solution or IL-2. At various time points, mice received [125I]UdR, and 20 h later tissues were removed and counted on a gamma analyzer. A proliferation index (PI) was calculated by dividing the mean cpm of organs of experimentally treated mice by the mean cpm of organs of control mice. Animals receiving TILs alone demonstrated small increases in [125I]UdR in the lungs, liver, and spleen of saline-treated controls (PI = 1.4, 1.6, and 1.7, respectively, on day 4), while animals treated with 50,000 U of IL-2 alone showed greater increases in the lungs, liver, kidneys, and spleen (PI = 3.9, 6.1, 3.3, and 15.8). Mice receiving TILs plus IL-2 demonstrated the highest levels of radiolabel incorporation in the same organs (PI = 10.5, 19.4, 10.2, and 22.4). Over a period of 10 days, TIL plus IL-2 treated animals continued to incorporate significantly greater amounts of [125I]UdR for as long as high-dose IL-2 was administered. Animals treated with TILs demonstrated increased incorporation of radiolabel with increasing doses of IL-2. Injection of irradiated TILs did not result in an increased uptake of [125I]UdR into these tissues, thus confirming that TIL proliferation is responsible for the radiolabel uptake in animals receiving TILs alone or TILs plus IL-2. Additionally, fluorescein-labeled anti-Thy-1.1 antibody identified proliferating TILs derived from congenic B6.PL Thy 1a/CY (Thy-1.1) animals in the lungs, spleen, and liver of recipient C57BL/6N (Thy 1.2) mice. In summary, we have demonstrated that adoptively transferred TILs distribute widely after i.v. injection and can proliferate in various tissues especially under the influence of exogenous IL-2.
