Distributed Hash Table Based Routing Algorithm for Wireless Sensor Networks (2014)

As the routing protocol can greatly influence the energy consumption of the sensor nodes in research field of wireless sensor networks. In this paper, we present a novel distributed hash table based routing algorithm for wireless sensor networks. Distributed hash table is a kind of distributed memory approach, of which the single node can be expanded to the whole Internet. Particularly, each node is controlled by a part of the whole resource space, and the related index information can be saved on it. In the proposed routing algorithm, each node in wireless sensor networks can be allocated an ID using hash functions. Afterwards, each node maintains a routing table, and then the selective information can be transmitted through the routing table. Next, we present a modified finger table named speedup finger table, and then used it in the wireless sensor networks routing algorithm. Finally, we design a series of experiments to verify the effectiveness of the proposed algorithm. Experimental results demonstrate that compared with the existing related works, the proposed routing algorithm is effective and can obviously reduce the energy consumption.
A survey on LPWA technology: LoRa and NB-IoT (2017)

By 2020, more than twenty five billion devices would be connected through wireless communications. In accordance with the rapid growth of the internet of things (IoT) market, low power wide area (LPWA) technologies have become popular. In various LPWA technologies, narrowband (NB)-IoT and long range (LoRa) are two leading technologies. In this paper, we provide a comprehensive survey on NB-IoT and LoRa as efficient solutions connecting the devices. It is shown that unlicensed LoRa has advantages in terms of battery lifetime, capacity, and cost. Meanwhile, licensed NB-IoT offers benefits in terms of QoS, latency, reliability, and range.
Mesomorphic behavior of new double swallow‐tailed compounds (1996)

Double swallow‐tailed compounds are special cases of tetracatenar mesogens (mesogens consisting of a rod‐like core and two half‐disc shaped moieties), where the branches are not attached directly to the terminal rings. Experiments are reported in which the middle part of the core and the length of the terminal chains were varied. The resulting effects on the transition temperatures and phase behavior are described and trends pointed out.
Immunotherapy Strategies for Multiple Myeloma: The Present and the Future (2013)

Growing knowledge of the complexities of the immune system have led to a better understanding of how it can be harnessed for the purpose of anticancer therapy. Moreover, recent success with immunotherapies for solid tumors, combined with novel therapeutic strategies against myeloma, heighten excitement at the prospect of improving clinical outcomes for myeloma by improving antitumor immunity. Increased understanding of myeloma tumor-associated antigens, availability of more potent vaccines, expanded immune-modulating therapies, development of agents that block immune-suppressive pathways, increased sophistication of adoptive cell therapy techniques and capitalization upon standard autologous transplant are all important standalone or combination strategies that might ultimately improve prognosis of patients with multiple myeloma.
Multi-user MIMO with outdated CSI: Training, feedback and scheduling (2011)

Conventional MU-MIMO techniques, e.g. Linear Zero-Forced Beamforming (LZFB), require sufficiently accurate channel state information at the transmitter (CSIT) in order to realize spectral efficient transmission (degree of freedom gains). In practical settings, however, CSIT accuracy can be limited by a number of issues including CSI estimation, CSI feedback delay between user terminals to base stations, and the time/frequency coherence of the channel. The latter aspects of CSIT-feedback delay and channel-dynamics can lead to significant challenges in the deployment of efficient MU-MIMO systems. Recently it has been shown by Maddah-Ali and Tse (MAT) that degree of freedom gains can be realized by MU-MIMO even when the knowledge of CSIT is completely outdated. Specifically, outdated CSIT, albeit perfect CSIT, is known for transmissions only after they have taken place. This aspect of insensitivity to CSIT-feedback delay is of particular interest since it allows one to reconsider MU-MIMO design in dynamic channel conditions. Indeed, as we show, with appropriate scheduling, and even in the context of CSI estimation and feedback errors, the proposed MAT scheme can have performance advantages over conventional MU-MIMO in such scenarios.
“Knitting up” the inter-dipole gaps in dielectric surfaces: an efficient route for high performance organic field-effect transistors (2012)

Suberoyl chloride (SCL) or ethylenediaminetetraacetic dianhydride (EDT) was added as crosslinking agents into the high-k cyanoethyl pullulan (CEP) polymer and the mixture was cured at temperatures of 90–120 °C. In the crosslinking reaction of the CEP polymer chain with SCL, ester groups were produced to knit up the gaps between the self-associated dipole clusters. Well-stacked pentacene molecular clusters were formed on the dipole clusters and 2-dimensional (2D) layer-by layer growth of the pentacene layer was observed. On the other hand, the dangling carboxylic acid (COOH) group in EDT-cured dielectrics disrupted the quasi-order by shielding the dipoles. This caused discontinuous 3D pentacene grains, which degraded the pentacene organic field effect transistor performance. A high field-effect mobility of ∼8.62 cm2 V−1 s−1, an on/off current ratio (Ion/Ioff) of ∼105 and a steep subthreshold slope (SS) of 0.099 V dec−1 were obtained using SCL as a cross-linking agent.
Absorbable material in vascular prostheses: a new device. (1980)

Seven to twenty cm long bypass grafts were inserted between the upper and lower part of the descending aorts of 20 young pids with end-to-side technique. The aorta between the anastomoses was closed by a ligature. As graft materials were used circular polyglactin 910 (Vicryl) mesh tubes (group I), external PTFE graft (Impra) and internal polyglactin mesh tube (group II), PTFE graft (group III) and external dacron mesh tube and internal polyglactin mesh tube (group IV). The biological process taking place in the grafted area was studied by light microscopy. The following observations were made: (1) The regenerative capacity of the pig aortic tissue permits 7 to 15 cm long polyglactin mesh grafts to be replaced by a new endothelialized vessel wall imitation. (2) When resorbable and non-resorbable materials were combined to form a composite graft (groups II and IV) the result proved to be a prosthesis with an internal covering of endothelialized arterial tissue.
Removal Of Baboon And Human Antiporcine Igg And Igm Natural Antibodies By Immunoadsorption (1995)

The safe and effective removal of xenoreactive antibodies in the peritransplant period is likely to be critical for the clinical application of xenotransplantation involving disparate donor species, such as the pig. In an effort to develop an improved method for antibody removal in xenotransplantation, we have studied reusable antihuman antibody (Ig) columns in vitro and in vivo. Two types of columns were tested: (1) an antihuman Ig column containing polyclonal sheep antihuman IgG (heavy- and light-chain-specific) conjugated to sepharose CL-4B (Ig-Therasorb), and (2) an antihuman Ig column using polyclonal antihuman IgM (mu-chain-specific) conjugated to sepharose. Passage of human or baboon plasma through the Ig-Therasorb column resulted in 97.5% and 78.4% mean reductions in total IgG and IgM, respectively. Reductions in total IgG and IgM correlated with lowering of antipig IgG (54-486 fold) and IgM (9-54 fold) antibody titers as assessed by pig endothelial cell ELISA. The ability of the Ig-Therasorb to significantly reduce IgM may be attributed to the light chain specificity of this column. With the anti-IgM column, marked reductions in total (82.6-83.9%) and antipig (27-54 fold) IgM in human and baboon plasma occurred, while levels of total and xenoreactive IgG were slightly affected. Other than a dilutional effect, neither column resulted in significant reduction in albumin, fibrinogen, factor 5, and factor 8. Repeated in vivo use of either column in baboons achieved reductions in IgG and IgM that closely followed the results of our in vitro studies. No subject morbidity or mortality occurred. Use of the Ig-Therasorb column with immunosuppression in two baboons receiving pig renal xenografts achieved sustained reductions in antipig antibodies and prevented hyperacute rejection. Subjects were sacrificed at 11 and 13 days posttransplant with functioning xenografts and were found to have no evidence of vascular xenograft rejection. We conclude that anti-Ig columns represent a safe and effective method for antibody removal, without several of the limitations of other antibody removal techniques. Also, columns appear to be safe for repeated antibody removal in the posttransplant period.
A transgenic model of autoimmune hemolytic anemia. (1992)

We made double transgenic mice bearing immunoglobulin heavy and light chain genes encoding an autoantibody against the mouse erythrocyte by the cross of C57BL/6 mice carrying the transgene for each chain of the immunoglobulin. Although no obvious disorders were found in the single-chain transgenic mice, severely anemic symptoms were found in some of the double transgenic mice, in which most B cells express, at least on their surface, the autoantibody reactive to self-antigens on the erythrocyte. Individual double-transgenic mice showed a wide variation of phenotypes between severe anemia and no symptoms. Both deletion and anergy of autoreactive B cells were seen in each individual mouse, but their relative contribution to self-tolerance was variable and not directly related to the severity of anemia or the amount of the autoantibody produced. This transgenic system provides a good autoimmune disease model for exploring its onset mechanism, and means of its treatment and prevention.
Opposing Actions of Heat Shock Protein 90 and 70 Regulate Nicotinamide Adenine Dinucleotide Phosphate Oxidase Stability and Reactive Oxygen Species Production (2012)

We conclude that Hsp90 binds to and regulates Nox protein stability. These actions are opposed by Hsp70 and CHIP, which promote the ubiquitination and degradation of Nox proteins and reduce reactive oxygen species production.
Natural Phenolic Compounds From Medicinal Herbs and Dietary Plants: Potential Use for Cancer Prevention (2009)

Natural phenolic compounds play an important role in cancer prevention and treatment. Phenolic compounds from medicinal herbs and dietary plants include phenolic acids, flavonoids, tannins, stilbenes, curcuminoids, coumarins, lignans, quinones, and others. Various bioactivities of phenolic compounds are responsible for their chemopreventive properties (e.g., antioxidant, anticarcinogenic, or antimutagenic and anti-inflammatory effects) and also contribute to their inducing apoptosis by arresting cell cycle, regulating carcinogen metabolism and ontogenesis expression, inhibiting DNA binding and cell adhesion, migration, proliferation or differentiation, and blocking signaling pathways. This review covers the most recent literature to summarize structural categories and molecular anticancer mechanisms of phenolic compounds from medicinal herbs and dietary plants.
Catalytic Reductive Alkylation of Secondary Amine with Aldehyde and Silane by an Iridium Compound (2005)

[reaction: see text] An efficient methodology for the reductive alkylation of secondary amine with aldehyde and Et(3)SiH using an iridium complex as a catalyst has been developed. For example, treatment of dibutylamine with butyraldehyde and Et(3)SiH (a 1:1:1 molar amount of amine, aldehyde, and silane) in 1,4-dioxane at 75 degrees C under the influence of a catalytic amount of [IrCl(cod)](2) gave tributylamine in quantitative yield. In this reaction, no reduction of aldehyde took place. It was found that IrCl(3), which is a starting material for preparation of iridium complexes such as [IrCl(cod)](2), acts as an efficient catalyst for the present reductive alkylation of amine. In addition, a cheaper, easy-to-handle, and environmentally friendly reducing reagent such as polymethylhydrosiloxane (PMHS) in place of Et(3)SiH was also useful. Thus, a variety of secondary amines could be alkylated by allowing them to react with aldehydes and PMHS in the presence of an iridium catalyst to afford the corresponding tertiary amines in good to excellent yields. From the deuterium label experiments, it was revealed that silane and water, generated during the formation of enamine by the reaction of amine and aldehyde, seem to behave as a hydrogen source. The catalytic cycle was discussed.
Development of a Single-Sided Flux Magnetic Coupler for Electric Vehicle IPT Charging Systems (2011)

Inductive power transfer is a practical method for recharging electric vehicles because it is safe, convenient, and reliable. The performance of the magnetic couplers that transfer power determines the overall feasibility of a complete system. Circular couplers are the most common topology in the literature; however, they have fundamentally limited coupling. Their flux patterns necessarily limit the operational air gap as well as tolerance to horizontal misalignment. A new polarized coupler topology [referred to as a double D (DD)] is presented, which overcomes these difficulties. DDs provide a charge zone five times larger than that possible with circular pads for a similar material cost and are smaller. A 0.31-m <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> DD enables 2 kW of power transfer over an oval area measuring 540 mm × 800 mm with a 200-mm air gap. Leakage magnetic fields have been investigated and show that circular and DD couplers operating under similar power transfer conditions produce similar levels. Both topologies can be designed and operated to ensure compliance with international guidelines.
Predicting sporulation events in a bioreactor using an electronic nose (2008)

An electronic nose (EN) based on a non- specific multi-sensor array was used to accurately estimate sporulation events and the spore concentration of Bacillus subtilis cultures. The array included 6 metal oxide sensors (MOS), 10 metal oxide semiconductor field effect transistors (MOSFET), one CO(2) infrared sensor and one humidity sensor. The EN was used to monitor the gas emissions from B. subtilis bioreactions during both batch and fed-batch operation. The signal pattern produced by the sensors was evaluated by principal component analysis (PCA) and training cultivations were used to build a model. The arc length of the PCA trajectories was successfully correlated to the off-line spore count; a strong linear correlation (R(2) = 0.992) between the numerical integration of the curves and the measured spore concentration was established. The fast responses of the sensors in combination with the robust correlation with the off-line determination of spore concentration establish this EN device as a convenient tool for monitoring sporulation events in bioprocesses.
Addressing the requirements of a dynamic corporate textual information base (1991)

AI-STARS is a lexicon-assisted full-text Information Retrieval system, designed for use in a dynamic corporate environment. In this paper, we explore how the requirements of such an environment have influenced many key aspects of the design and implementation of the AI-STARS system. We promote the use of "views" to create logical partitions in large, heterogeneous databases, and argue that storing not only article instances, but also class defhitions, stored queries, display templates and linguistic data in a single object repository has consequences that can be exploited for schema and lexicon evolution, security and subject filtering, information navigation, and data distribution. structured information objects. Next we consi&r querying on semi-stmctured objects and show how the notion of storing queries can & exploited to support multiple logical "views" of large databases. We then describe how our lexical and linguistic knowledge can take advantage of the object-oriented infrastmcture as well, arguing that a uniform representation of heterogeneous objects simplifies the tasks of data security, p~tioning, and distribution. We conclude with a dkcussion of implementation status and issues, related research, and user interface implications.

Materiales y Metodos: Participaran del estudio 15 mujeres saludables, fisicamente activas, en que fueron evaluados en el ejercicio de media sentadilla, en los parametros: Contraccion Voluntaria Isometrica Maxima (CVIM); Electromiografia de Superficie (EMG) en los musculos Vasto Medial (VM), Vasto Lateral (VF) y Recto Femoral (RF), y la relacion EMG/KGftotal. Las voluntarias fueron sometidas a un estiramiento de flexion de las rodillas, e hicieran 4 tiempos de sustentacion 0”, 10”, 30” y 60” segundos respectado una aleatorizacion de las sustentaciones y un intervalo de 72 horas entre cada tiempo de estiramiento y la ejecucion de las pruebas neuromusculares. El analisis estadistico utilizo el teste de Shapiro Wilk para verificar la distribucion de la muestra y el de Anova de Medidas Repetidas para verificar el comportamiento de las variables entre los estimulos de estiramiento. Resultados: No fue posible identificar diferencias significativas en la CVIM entre los tiempos de sustentacion. En la variable EMG fue posible identificar diferencias significativas en el VM entre el SE y 30”, y el SE y 60”, ademas de 10” y 30”. Conclusion: Se puede concluir que los estimulos de estiramientos propuestos no afectan los parametros neuromusculares estudiados, pero los estimulos en los 30 y segundos parecen traer mejores resultados en la fuerza. En el en tanto hay que buscar futuras propuestas en que se controlen la intensidad del estiramiento, para conocer sus efectos en las cuantificaciones neuromusculares EnglishIntroduction: The aim of the study was to verify the interference of stretching protocols in the neuromuscular parameters. Materials Methods: The study included 15 healthy, physically active women, who were evaluated in the half-squat exercise, in the parameters: maximal voluntary contraction (MVC), surface electromyography (EMG) in the Vastus Medialis (VM), Vastus Lateralis (VF) Rectus Femoris (RF), the EMG / KGftotal relationship. The volunteers underwent a knee flexion stretch, had 4 sustaining times No stretching (NS), 10, 30 and 60 seconds, a randomization of the supports was observed a 72-hour interval between each stretching time the performance of neuromuscular tests. The statistical analysis used the Shapiro Wilk test to verify the distribution of the sample the Anova of Repeated Measures to verify the behavior of the variables between the stretching. Results: It was not possible to identify significant differences in the MVC between lift times. In the variable EMG it was possible to identify significant differences in the VM between the NS 30 , the NS 60, in addition to 10 and 30. Conclusion: It can be concluded that the proposed stretching stimuli do not affect neuromuscular parameters studied, but stimuli in the 30s 60s seem to bring better results in strength. While in future proposals must be sought in the intensity of stretching is controlled, for their effects on neuromuscular quantifications.
Characterization of Adsorbed Ionic Surfactants on a Mica Substrate (1996)

An AFM study is presented to investigate the morphology of adsorbed cationic surfactants on mica substrates. At low surfactant concentrations and low pH values, discrete aggregates of adsorbed surfactants are found on the surface. As the surfactant concentration is increased, these aggregates become more organized into elongated cylindrical shapes. The continuity of the network of patches increases until a concentration just below the cmc. At this concentration, the patches become continuous “wormlike” admicelles on the surface. Contact angle measurements corroborate the change in the surface properties from hydrophobic at low surfactant concentrations to hydrophilic at concentrations slightly below the cmc. Force versus distance curves also clearly indicate a change in surface morphology. It is clear from our observations that the formation of dense continuous monolayers or bilayers does not occur as postulated earlier. Indeed our observations suggest the formation of discrete surfactant aggregates on the surface which under certain conditions (high pH and high surfactant concentration) become continuous and form wormlike admicelles on the mica surface. This change in surfactant morphology from adsorbed surfactant aggregates to more continuous structures is also responsible for the transition from hydrophilic to hydrophobic surface properties. It is also shown that pH and salt concentration play an important role in this transition.
Analysis of Figure Of Merit - power transistor's qualitative parameter (2015)

In order to meet upcoming regulations and standards for dc-dc converter's efficiency, the analysis of qualitative indicator of power transistor was investigated. FOM - figure of merit, represents a measure of semiconductor suitability for high frequency power transistor application. This article deals with the analysis of FOM of several power MOSFETs, whereby main parameters are taken into consideration for calculation purposes. In order to verify faithfulness of FOM, the parametrical simulation analysis of hard-switching commutation mode for given parameters of target application (front-end converters) has been done. After it the switching losses together with conduction losses were determined, and consequently comparisons between the amount of transistor's losses and its FOM indicator are provided.
The knee pain map: Reliability of a method to identify knee pain location and pattern (2009)

The majority of participants could identify the location of their knee pain, and trained interviewers could reliably record those locations. The variation in locations suggests that there are multiple sources of pain in knee OA. Additional studies are needed to determine whether specific knee pain patterns correlate with discrete pathologic findings on radiographs or magnetic resonance images.
Carbon-doped GaAs single junction solar microcells grown in multilayer epitaxial assemblies (2013)

A stack design for carbon-doped GaAs single junction solar microcells grown in triple-layer epitaxial assemblies is presented. As-grown materials exhibit improved uniformity of photovoltaic performance compared to zinc-doped systems due to the lack of mobile dopants while a slight degradation exists in middle and bottom devices. Detailed electrical and optical characterizations of devices together with systematic studies of acceptor reactivation reveal carbon-related defects accompanied by carrier compensation, and associated scattering and recombination centers are primarily responsible for the degraded contact properties and photovoltaic performance, resulting from prolonged thermal treatments of early-grown materials during the multilayer epitaxial growth.
