Energy Efficient Data Retrieval and Caching in Mobile Peer-to-Peer Networks (2005)

Mobile peer-to-peer (MP2P) networks consist of mobile devices that communicate with each other via short-range wireless transmissions to facilitate sharing of information among them. Such networks present a constrained communication environment due to fundamental limitations of battery power and wireless bandwidth, and users' frequent mobility. These characteristics of MP2P networks make scalable data retrieval a challenging problem. In this paper, we propose a novel scheme, called proximity regions for caching in cooperative MP2P networks (PReCinCt), to efficiently support scalable data retrieval in large-scale MP2P networks. In the PReCinCt scheme, the network topology is divided into geographical regions where each region is responsible for a set of keys representing the data. Each key is then mapped to a region location based on a geographical hash function. A geographic-aided routing protocol is used to route traffic of each data retrieved. In order to further save bandwidth for each data retrieved, PReCinCt incorporates a cooperative caching scheme that caches relevant data among a set of peers in a region. Simulation results show that the proposed scheme achieves significant improvements in average latency and energy consumption.
Design and analysis of collaborative diversity protocols for wireless sensor networks (2005)

We consider wireless sensor networks where all the sensor nodes share the same channel and transmit collaboratively in a quasi-static Rayleigh fading environment. Intuition suggests that collaborative communication can achieve a higher diversity gain than traditional SISO systems. Based on a decode-and-forward approach, we propose spectrally efficient variable-rate two-phase protocols that can achieve full diversity and analyze the effect of node geometry on their performance in terms of the outage probability of mutual information. Numerical results show that, provided the collaborator node is close to the source node, full diversity gain can he readily achieved without loss of bandwidth efficiency.

An Internalization-Competent Influenza Hemagglutinin Mutant Causes the Redistribution of AP-2 to Existing Coated Pits and Is Colocalized with AP-2 in Clathrin Free Clusters (1999)

Image correlation spectroscopy and cross correlation spectroscopy were used to demonstrate that approximately 25% of the internalization-competent influenza virus hemagglutinin mutant, HA+8, is colocalized with clathrin and AP-2 at the plasma membrane of intact cells, while wild-type HA (which is excluded from coated pits) does not colocalize with either protein. Clathrin and AP-2 clusters were saturated when HA+8 was overexpressed, and this was accompanied by a redistribution of AP-2 into existing coated pits. However, de novo coated pit formation was not observed. In nontreated cells, the number of clusters of clathrin or AP-2 colocalized with HA+8 was always comparable. Hypertonic treatment which disperses the clathrin lattices resulted in more clusters containing AP-2 and HA+8 than clathrin and HA+8. Less colocalization of HA+8 with clathrin was also observed after cytosol acidification, which causes the formation of deeply invaginated pits, where the HA+8 may be inaccessible to extracellular labeling by antibodies, and blocks coated vesicle budding. However, cytosol acidification elevated the number of clusters containing both HA+8 and AP-2, suggesting an increase in their level of association outside of the deep invaginations. Our results imply that AP-2 and HA+8 can colocalize in clusters devoid of clathrin, at least in cells treated to alter the clathrin lattice structure. Although we cannot ascertain whether this also occurs in untreated cells, we propose that AP-2 binding to membrane proteins carrying internalization signals can occur prior to the binding of AP-2 to clathrin. While such complexes can in principle serve to recruit clathrin for the formation of new coated pits, the higher affinity of the internalization signals for clathrin-associated AP-2 [Rapoport, I., et al. (1997) EMBO J. 16, 2240-2250] makes it more likely that once the AP-2-membrane protein complexes form, they are quickly recruited into existing coated pits.
Enhancing computer vision to detect face spoofing attack utilizing a single frame from a replay video attack using deep learning (2016)

Recently, automatic face recognition has been applied in many web and mobile applications. Developers integrate and implement face recognition as an access control into these applications. However, face recognition authentication is vulnerable to several attacks especially when an attacker presents a 2-D printed image or recorded video frames in front of the face sensor system to gain access as a legitimate user. This paper introduces a non-intrusive method to detect face spoofing attacks that utilize a single frame of sequenced frames. We propose a specialized deep convolution neural network to extract complex and high features of the input diffused frame. We tested our method on the Replay Attack dataset which consists of 1200 short videos of both real-access and spoofing attacks. An extensive experimental analysis was conducted that demonstrated better results when compared to previous static algorithms results.
Accessible light detection and ranging: estimating large tree density for habitat identification (2016)

Abstract Large trees are important to a wide variety of wildlife, including many species of conservation concern, such as the California spotted owl ( Strix occidentalis occidentalis ). Light detection and ranging (Li DAR ) has been successfully utilized to identify the density of large‐diameter trees, either by segmenting the Li DAR point cloud into individual trees, or by building regression models between variables extracted from the Li DAR point cloud and field data. Neither of these methods is easily accessible for most land managers due to the reliance on specialized software, and much available Li DAR data are being underutilized due to the steep learning curve required for advanced processing using these programs. This study derived a simple, yet effective method for estimating the density of large‐stemmed trees from the Li DAR canopy height model, a standard raster product derived from the Li DAR point cloud that is often delivered with the Li DAR and is easy to process by personnel trained in geographic information systems ( GIS ). Ground plots needed to be large (1 ha) to build a robust model, but the spatial accuracy of plot center was less crucial to model accuracy. We also showed that predicted large tree density is positively linked to California spotted owl nest sites.
Use Of Plants To Remediate Soil Polluted With Oil (2015)

In the present investigation the growing and development ability of various annual and perennial plants to grow on model peat substrate artificially polluted with oil products in the range of concentrations from 1 to 5% was evaluated. The highest tolerance towards peat contamination by oil products has been demonstrated by three annual crops (maize, oat and lupine). These plants were tested for phytoremediation of polluted black soil from the area of oil refinery plant (Mazeikiai, Lithuania), which was treated by association of oil oxidizing bacteria up to residual concentration of the oil products of 4.5 %. The maize plants revealed the highest remediation ability: oil content in the soil decreased by ~ 1.5 times in one month plant vegetation.

Electroplating Copper onto Resistive Barrier Films (2000)

An analytical solution for the metal resistance‐controlled plating current distribution on circular wafers is obtained for determining the conditions under which a uniform metal film can be electrodeposited on a resistive film. Results indicate that, when using conventional copper plating solutions, uniform films cannot be deposited on 500 Å thick barrier layers consisting of Ta (or more resistive metals) on 200 mm wafers, regardless of plating current density or the use of pulse reverse plating. Uniformity can be characterized by a dimensionless polarization parameter that reflects the influences of current density and physical and chemical properties. Of these properties, the only one that can be varied enough to allow Cu plating on a barrier film is the plating exchange current density, . By lowering the copper concentration and thus in the plating bath by one or two orders of magnitude below levels that are commonly employed, the terminal effect can be reduced to the point where a uniform conformal conduction layer can be electrodeposited. Subsequently, the bulk copper film can be plated at high rates. © 2000 The Electrochemical Society. All rights reserved.
Postoperative wound infection. A poor prognostic sign for patients with head and neck cancer (1992)

Design of Anion Exchange Membranes and Electrodialysis Studies for Water Desalination (2016)

Anion exchange membranes are highly versatile and nowadays have many applications, ranging from water treatment to sensing materials. The preparation of anion exchange membranes (AEMs) from brominated poly(2,6-dimethyl-1,6-phenylene oxide) (BPPO) and methyl(diphenyl)phosphine (MDPP) for electrodialysis was performed. The physiochemical properties and electrochemical performance of fabricated membranes can be measured by changing MDPP contents in the membrane matrix. The influence of a quaternary phosphonium group associated with the removal of NaCl from water is discussed. The prepared membranes have ion exchange capacities (IEC) 1.09-1.52 mmol/g, water uptake (W<sub>R</sub>) 17.14%-21.77%, linear expansion ratio (LER) 7.96%-11.86%, tensile strength (TS) 16.66-23.97 MPa and elongation at break (<i>E</i><sub>b</sub>) 485.57%-647.98%. The prepared anion exchange membranes were employed for the electrodialytic removal of 0.1 M NaCl aqueous solution at a constant applied voltage. It is found that the reported membranes could be the promising candidate for NaCl removal via electrodialysis.
Selective Application of Insecticides for Prevention of Southern Pine Beetle Attack12 (1982)

Attacks by Dendroctonus frontalis Zimmermann were prevented on southern pines by applications of lindane or chlorpyrifos to the entire bole and to the top half of the bole only. Treatment of the basal 2 m and the lower half of tree boles did not prevent attacks. By applying toxicants to only the top half of trees, insecticide volume was reduced by over 30%, and contamination of nontarget areas near the base of the trees was significantly reduced.
Shionone Attenuates Sepsis-Induced Acute Kidney Injury by Regulating Macrophage Polarization via the ECM1/STAT5 Pathway (2022)

Backgrounds To date, there are no specific drugs approved for the treatment of sepsis associated acute kidney injury (AKI). Shionone is a natural component with anti-inflammatory activity. In this study, we sought to determine the functional role of Shionone in sepsis-induced AKI. Methods Animal models of AKI were constructed by cecum ligation and puncture (CLP) surgery. C57BL/6 mice were randomly assigned to the Sham, CLP, 10 mg/kg DXM, 50 mg/kg Shionone and 100 mg/kg Shionone groups. RAW264.7 treated with lipopolysaccharides (LPS) was used as an in vitro sepsis model and cells were divided into control, LPS, 1 μg/mL Shionone and 2 μg/mL Shionone groups. The pathological status was assessed by Hematoxylin-Eosin (HE) staining assay, protein expressions were detected by immunofluorescence staining and Western blot, macrophage typing was detected by flow, and the levels of pro-inflammatory factors (IL-6, IL-12, IL-1β, TNF-α) and anti-inflammatory factors (IL-10 and TGF-β) were measured using the corresponding kits. Results ECM1 is highly expressed in tissue-infiltrating macrophages under inflammatory conditions. It has been observed that Shionone inhibits the expression of ECM1 and attenuates sepsis-induced injury in kidney and inflammatory factor levels in serum. In addition, Shionone may reduce inflammatory factor levels through the promotion of M2 macrophages by GM-CSF/STAT5/Arg1 pathway to alleviate sepsis induced inflammation in vitro . Conclusion These findings demonstrate that Shionone can alleviate sepsis-induced AKI by promoting M2 macrophage polarization through regulating the ECM1/STAT5 pathway.

A new genome allows the identification of genes associated with natural variation in aluminium tolerance in Brachiaria grasses (2020)

Toxic concentrations of aluminium cations and low phosphorus availability are the main yield-limiting factors in acidic soils, which represent half of the potentially available arable land. Brachiaria grasses, which are commonly sown as forage in the tropics because of their resilience and low demand for nutrients, show greater tolerance to high concentrations of aluminium cations (Al3+) than most other grass crops. In this work, we explored the natural variation in tolerance to Al3+ between high and low tolerant Brachiaria species and characterized their transcriptional differences during stress. We identified three QTLs (quantitative trait loci) associated with root vigour during Al3+ stress in their hybrid progeny. By integrating these results with a new Brachiaria reference genome, we identified 30 genes putatively responsible for Al3+ tolerance in Brachiaria. We observed differential expression during stress of genes involved in RNA translation, response signalling, cell wall composition, and vesicle location homologous to aluminium-induced proteins involved in limiting uptake or localizing the toxin. However, there was limited regulation of malate transporters in Brachiaria, which suggests that exudation of organic acids and other external tolerance mechanisms, common in other grasses, might not be relevant in Brachiaria. The contrasting regulation of RNA translation and response signalling suggests that response timing is critical in high Al3+-tolerant Brachiaria.
Fundamental transmitting properties of carbon nanotube antennas (2005)

Fundamental properties of dipole transmitting antennas formed by carbon nanotubes are investigated. Since carbon nanotubes can be grown to centimeter lengths, and since they can be metallic, the properties of carbon nanotubes as antenna elements are of fundamental interest. In this paper, dipole carbon nanotube antennas are investigated via a classical Hallen's-type integral equation, based on a quantum mechanical conductivity. The input impedance, current profile, and efficiency are presented, and the radiation pattern is discussed, as are possible applications.
Enhanced tumor suppression by a p14ARF/p53 bicistronic adenovirus through increased p53 protein translation and stability. (2003)

The p53 tumor suppressor controls a cell cycle arrest and apoptosis pathway that is central to tumor suppression and often disrupted in cancer. The accumulation and activity of p53 are positively controlled by the p14/ARF tumor suppressor and full restoration of the pathway in cancer cells may require that both p53 and p14ARF be supplied [corrected]. To address this issue, we have constructed a bicistronic adenoviral vector encoding the two proteins (Adp14/p53) and compared its tumor suppressor activity with that of a single gene vector for p53 (Adp53). We find that tumor cells treated with Adp14/p53 undergo a much sharper decrease in viability with increasing multiplicities of infection than do cells treated with Adp53, even when cells express endogenous p14ARF. Adp14/p53 is also more effective than is a combination of single gene vectors for p14 and p53. The sharper decrease in cell viability after treatment of cells with Adp14/p53 correlates with an increased rate of p53 protein synthesis and a decreased rate of p53 protein turnover, leading to increased steady-state levels of p53 protein and increased levels of p53 downstream targets mdm2, p21waf1, and bax. Adp14/p53 treatment leads to an elevated bax:bcl2 ratio and induction of apoptosis in vitro and in vivo, coupled with a failure of the tumor cells to induce neovascularization in vivo. The results indicate that endogenous p14ARF expression may be insufficient to ensure efficient accumulation of ectopic p53 after gene transfer and demonstrate that for tumor suppression, bicistronic coexpression of p14ARF and p53 is superior to p53 alone. The results show that in this setting, p14ARF promotes p53 accumulation by increasing p53 protein synthesis, in addition to its well-characterized ability to oppose mdm2-mediated degradation of p53.
A p-norm Flow Optimization Problem in Dense Wireless Sensor Networks (2008)

In a network with a high density of wireless nodes, we model flow of information by a continuous vector field known as the information flow vector field. We use a mathematical model that translates a communication network composed of a large but finite number of sensors into a continuum of nodes on which information flow is formulated by a vector field. The magnitude of this vector field is the intensity of the communication activity, and its orientation is the direction in which the traffic is forwarded. The information flow vector field satisfies a set of Neumann boundary conditions and a partial differential equation (PDE) involving the divergence of information, but the divergence constraint and Neumann boundary conditions do not specify the information flow vector field uniquely, and leave us freedom to optimize certain measures within their feasible set. Therefore, we introduce a <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">p-norm</i> flow optimization problem in which we minimize the <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">p-norm</i> of information flow vector field over the area of the network. This problem is a convex optimization problem, and we use sequential quadratic programming (SQP) to solve it. SQP is known for numerical stability and fast convergence to the optimal solution in convex optimization problems. By using standard SQP on <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">p-norm</i> flow optimization, we prove that the solution of each iteration of SQP is uniquely specified by an elliptic PDE with generalized Neumann boundary conditions. The <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">p-norm</i> flow optimization shows interesting properties for different values of <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">p</i> . For example, if p is close to one, the information routes resemble the geometric shortest paths of the sources and sinks, and for <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">p</i> = 2, the information flow shows an analogy to electrostatics. For infinitely large values of <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">p</i> , the problem minimizes the maximum magnitude of the information vector field over the network, and hence it achieves maximum load balancing.
Marine heatwaves drive recurrent mass mortalities in the Mediterranean Sea (2022)

Climate change is causing an increase in the frequency and intensity of marine heatwaves (MHWs) and mass mortality events (MMEs) of marine organisms are one of their main ecological impacts. Here, we show that during the 2015-2019 period, the Mediterranean Sea has experienced exceptional thermal conditions resulting in the onset of five consecutive years of widespread MMEs across the basin. These MMEs affected thousands of kilometers of coastline from the surface to 45 m, across a range of marine habitats and taxa (50 taxa across 8 phyla). Significant relationships were found between the incidence of MMEs and the heat exposure associated with MHWs observed both at the surface and across depths. Our findings reveal that the Mediterranean Sea is experiencing an acceleration of the ecological impacts of MHWs which poses an unprecedented threat to its ecosystems' health and functioning. Overall, we show that increasing the resolution of empirical observation is critical to enhancing our ability to more effectively understand and manage the consequences of climate change.
Alternating copolymers of tetramethylene urea with 2,2‐dimethyltrimethylene carbonate and ethylene carbonate; preparation of the corresponding polyurethanes (1997)

Abstract Copolymerization of tetramethylene urea (TeU, 1 ) with the cyclic carbonates 2,2‐dimethyltrimethylene carbonate (DTC, 2 ) and ethylene carbonate (EC, 3 ) results in the polyurethanes 4 and 5 with an approximate number‐average molecular weight of 20 000 and a polydispersity index of two. Polyurethane 4 is an amorphous material with a glass transition temperature of 26.3°C; polyurethane 5 is a semicrystalline material with a melting temperature of 208°C. Distinct copolymerization mechanisms are proposed for the formation of polyurethane 4 and 5 , respectively.
Increased Enterocyte Apoptosis in Inflamed Areas of Crohn's Disease (2003)

Enterocyte apoptosis is increased in involved areas of Crohn's disease. This increase is not mediated by a Fas-Fas ligand mechanism or by an abnormal E-cadherin distribution. Increased matrix metalloproteinase-1 release from lamina propria mononuclear cells might be one of the possible mechanisms responsible for the increased enterocyte apoptosis in Crohn's disease.
Target recognition–induced NK-cell responses (2010)

In this issue of Blood , Fauriat and colleagues provide a thorough study of the pattern and timing of NK-cell cytokine and chemokine secretion in response to target cell recognition. Most importantly, the authors demonstrate that CD56 dim NK cells rather than CD56 bright NK cells are the major cytokine and chemokine producer upon target recognition. 1
