Effects of Location Awareness on Concurrent Transmissions for Cognitive Ad Hoc Networks Overlaying Infrastructure-Based Systems (2009)

Through wide-band spectrum sensing, cognitive radio (CR) can identify the opportunity of reusing the frequency spectrum of other wireless systems. However, wide-band spectrum sensing requires energy consumption processes. In this paper, we aim to relieve the burden of spectrum scanning in a CR system by means of location awareness. We investigate to what extent a CR system with location awareness capability can establish a scanning-free region where a peer-to-peer connection of the secondary CR users can coexist with an infrastructure-based connection of the primary user. We compute the concurrent transmission probability of a peer-to-peer connection and an infrastructure-based connection in a system based on the carrier sense multiple access with collision avoidance (CSMA/CA) medium access control (MAC) protocol. It has been shown that the frequency band of the legacy system can be reused up to 45% by the overlaying cognitive ad hoc network if certain location techniques help CR users locate primary and other secondary users. In summary, a CR system equipped with location awareness techniques can dramatically reduce the need of spectrum sensing thanks to the capability of identifying the concurrent transmission region in a hybrid infrastructure-based and ad hoc overlaying systems. Hence, from another aspect, the issue of wide-band spectrum sensing in CR systems is resolved fundamentally.
The normal Langerhans cell and the LCH cell. (1994)

The epidermal Langerhans cell is the bone marrow-derived dendritic, antigen-presenting cell of the skin. It is characterised by a unique intracytoplasmic organelle--the Birbeck granule--and constitutively expresses class II MHC molecules and the CD1a glycoprotein. The Langerhans cell represents one of the most potent antigen-presenting cells of the body, and fulfils an important role in detecting foreign antigen entering the body through the skin and in immune surveillance. The distribution of Langerhans cells is restricted to the skin, lymph nodes, bronchial mucosa and thymus. The discovery by Nézelof in 1973 that the lesional cells in the disease then called 'Histiocytosis X' contained Birbeck granules established the close relationship between the Langerhans cell and this disease and led ultimately to the adoption of the name Langerhans cell histiocytosis to replace the older term. The LCH cell expresses the phenotype of a Langerhans cell apparently 'fixed' at an early stage of cell activation. The LCH cell is, however, functionally defective in antigen presentation, and the tissue distribution of the disease--affecting bone, skin, lymph node, lung, liver, spleen, CNS, gastro-intestinal tract and bone marrow--is quite different from the normal distribution of the Langerhans cell. Studies are now under way throughout the world to investigate the relationship between the normal Langerhans cell and the LCH cell. Specifically we need to identify whether the LCH cell is a cell arrested at a specific time in normal Langerhans cell ontogeny or if it represents a response to a biological insult to the mature Langerhans cell or its precursors.
Terahertz Trace Gas Spectroscopy Based on a Fully-Electronic Frequency-Comb Radiating Array in Silicon (2016)

A silicon integrated circuit is reported for radiating picosecond pulses with tunable repetition rate, covering frequencies from 30 GHz to 1.03 THz. This source is used in a gas spectroscopy setup to measure the absorption lines of ammonia and water in the terahertz region.
Brain Trauma Induces Massive Hippocampal Neuron Death Linked to a Surge in β-Amyloid Levels in Mice Overexpressing Mutant Amyloid Precursor Protein (1998)

Although brain trauma is a risk factor for Alzheimer's disease, no experimental model has been generated to explore this relationship. We developed a model of brain trauma in transgenic mice that overexpress mutant human amyloid precursor protein (PDAPP) leading to the appearance of Alzheimer's disease-like beta-amyloid (Abeta) plaques beginning at 6 months of age. We induced cortical impact brain injury in the PDAPP animals and their wild-type littermates at 4 months of age, ie, before Abeta plaque formation, and evaluated changes in posttraumatic memory function, histopathology, and regional tissue levels of the Abeta peptides Abeta1-40 and Abeta1-42. We found that noninjured PDAPP mice had impaired memory function compared to noninjured wild-type littermates (P < 0.01) and that brain-injured PDAPP mice had more profound memory dysfunction than brain-injured wild-type littermates (P < 0.001). Although no augmentation of Abeta plaque formation was observed in brain-injured PDAPP mice, a substantial exacerbation of neuron death was found in the hippocampus (P < 0.001) in association with an acute threefold increase in Abeta1-40 and sevenfold increase in Abeta1-42 levels selectively in the hippocampus (P < 0.01). These data suggest a mechanistic link between brain trauma and Abeta levels and the death of neurons.
Simultaneous EEG Recordings with Dry and Wet Electrodes in Motor-Imagery (2011)

Robust dry EEG electrodes are arguably the key to making EEG Brain-Computer Interfaces (BCIs) a practical technology. Existing studies on dry EEG electrodes can be characterized by the recording method (stand-alone dry electrodes or simultaneous recording with wet electrodes), the dry electrode technology (e.g. active or passive), the paradigm used for testing (e.g. event-related potentials), and the measure of performance (e.g. comparing dry and wet electrode frequency spectra). In this study, an active-dry electrode prototype is tested, during a motor-imagery task, with EEG-BCI in mind. It is used simultaneously with wet electrodes and assessed using classification accuracy. Our results indicate that the two types of electrodes are comparable in their performance but there are improvements to be made, particularly in finding ways to reduce motion-related artifacts.
Fluorogenic selective and differential medium for isolation of fecal streptococci (1983)

Of 44 fluorogenic substrates tested for their ability to differentiate species of fecal streptococci, four yielded species-differentiating reactions. The remaining substrates either yielded uniformly positive, negative, or variable strain-dependent reactions. One substrate, 4-methylumbelliferone-alpha-D-galactoside, was hydrolyzed by Streptococcus bovis and S. faecium and its biotypes. 4-Methylumbelliferone-alpha-D-galactoside and a colorimetric starch substrate were incorporated into the fecal streptococcal selective medium of Donnelly and Hartman (Appl. Environ. Microbiol. 35:576-581, 1978). Three phenotypic groups were identifiable on the new fluorescent gentamicin-thallous-carbonate agar: (i) starch hydrolysis and fluorescence (S. bovis), (ii) no starch hydrolysis but fluorescence (S. faecium and its biotypes), and (iii) no starch hydrolysis or fluorescence (S. faecalis, S. avium, S. equinus, S. mitis, and S. salivarius). Of the presumptive identifications from sewage, swine, and bovine samples, 86% were confirmed as being correct. The new medium has potential application in water, food, environmental, and possibly clinical microbiology.
Relationship between the Developmental Programs Controlling Nuclear and Cytoplasmic Maturation of Mouse Oocytes (1994)

This paper focuses on the relationship between the developmental programs that regulate nuclear and cytoplasmic maturation of mouse oocytes. As oocytes near completion of their growth phase, they become competent to resume meiosis when isolated from the small antral follicles and cultured, but the progression of meiosis in many of these oocytes stops at metaphase I (MI). With further growth and development at the germinal vesicle (GV) stage, however, these oocytes become competent to complete nuclear maturation and progress to metaphase II (MII). In this study, about 44% of the oocytes were arrested at MI after isolation from the small antral follicles of 18-day-old mice and culture for 16 to 17 hr. Upon insemination, these MI-arrested oocytes produced the first polar body, formed pronuclei, cleaved, and developed to the blastocyst stage. Seventy five percent of these blastocysts were triploid, the remainder were diploid. Treatment of MI-arrested oocytes with calcium ionophore resulted in the completion of the first meiotic division and parthenogenetic activation. Moreover, while the pattern of proteins synthesized in MI-arrested oocytes was quite different from that of normal MI oocytes as determined by [35S]methionine labeling and two-dimensional gel electrophoresis, it was similar to that of MII-arrested oocytes. It was therefore concluded that some critical aspects of cytoplasmic maturation can occur in oocytes whose nuclear maturation is arrested at MI. In addition, triggers that promote entry of MII-arrested oocytes into anaphase II are sufficient to drive MI-arrested oocytes into anaphase I and to produce the first polar body when the triggers are generated in mature cytoplasm. The developmental capacity of MII oocytes that matured in vitro after isolation from 18- or 26-day-old mice were compared. The frequency of fertilization and cleavage to the 2-cell stage was equal in both groups. In surprising contrast, the ability to complete the 2-cell stage to blastocyst transition occurred much more frequently when the oocytes were from the 26- than the 18-day-old mice (82 and 27%, respectively). Thus, even though both groups of oocytes had completed nuclear maturation by progressing to MII, oocytes from the smaller follicles of the younger mice were deficient in maternal factors essential for development of embryos beyond the 2-cell stage. Further differentiation of these GV-stage oocytes of small antral follicles is therefore required to produce eggs competent of completing preimplantation development.
AOCD: A Multi-agent Based Open Architecture for Decision Support Systems (2006)

Despite the critical need for an open architecture in Decision Support System (DSS) design, present DSS architectural design are unable to provide a fundamental solution to enhance the flexibility, connectivity, compatibility, and intelligence of a DSS. In this paper, we present a novel multi-agent-based architecture for DSS, called Agent-based Open Connectivity for Decision support systems (AOCD). The AOCD architecture adopts a hybrid agent network topology that makes use of a unique feature called Matrix-agent connection. This architecture is able to overcome the difficulties in concurrent control and synchronous communication problems that plague many decentralized systems. Performance analysis has been carried out on this architecture and we find that it is able to provide a high degree of flexibility and efficiency compared with other architectures.
Pre-Si estimation and compensation of SRAM layout deficiencies to achieve target performance and yield (2008)

With technology scaling, process constraints and imperfections result in significant variation of post-Si performance and stability of SRAM from designed/target pre-Si parameters. Modification/ re-optimization of SRAM cell and/or tuning of process parameters to meet target performance and stability are limited by area constraints and involve several technology ramp-up cycles. For reducing access failures, if process is not fine tuned, memory access clock cycle period may need to be increased thereby compromising performance. We propose a design methodology to meet the target performance and reduce access failures by tuning the SRAM array peripherals instead of tuning the SRAM cell and process parameters. Proposed design methodology is supported by numerical framework and validated by simulation results on 45nm PDSOI technology. We further show that our methodology does not impact the READ stability of a cell.
DNA damage by antitumor acridines mediated by mammalian DNA topoisomerase II. (1986)

Antitumor drugs from many chemical classes have been shown to induce protein-linked DNA breaks in cultured mammalian cells and in vitro in the presence of purified mammalian DNA topoisomerase II. The possibility that mammalian DNA topoisomerase II is an intracellular target which mediates drug-induced DNA breaks is supported by the following studies using 4'-(9-acridinylamino)methane-sulfon-m-anisidide (m-AMSA): (a) a single m-AMSA-dependent DNA cleavage activity copurified with calf thymus DNA topoisomerase II activity at all chromatographic steps of the enzyme purification; (b) m-AMSA-induced DNA cleavage by this purified activity resulted in the covalent attachment of protein to the 5'-ends of the DNA via a tyrosyl phosphate bond. This covalently linked protein has the same reduced molecular weight as purified calf thymus DNA topoisomerase II. The possibility that topoisomerase II-mediated DNA breaks may be responsible for cytotoxicity has also been investigated using a number of m-AMSA-related acridines. The level of topoisomerase II-mediated DNA breaks in vitro strongly correlates with the level of protein-linked DNA breaks in cultured cells and drug-induced cytotoxicity. These results suggest that mammalian DNA topoisomerase II may be a cytotoxic target of antitumor acridines.

Transparent Debugging of Dynamically Optimized Code (2009)

Debugging programs at the source level is essential in the software development cycle. With the growing importance of dynamic optimization, there is a clear need for debugging support in the presence of runtime code transformation. This paper presents a framework, called DeDoc, and lightweight techniques that allow debugging at the source level for programs that have been transformed by a trace-based binary dynamic optimizer. Our techniques provide full transparency and hide from the user the effect of dynamic optimizations on code statements and data values. We describe and evaluate an implementation of DeDoc and its techniques that interface a dynamic optimizer with a native debugger. Our experimental results indicate that DeDoc is able to report over 96% of values, that are otherwise not reportable due to code transformations, and incurs less than 1% performance overhead.
Perspective: edible vaccines—a concept coming of age (1998)

In addition to their traditional role as a source of natural medicines, it is now possible to genetically engineer plants to produce pharmaceuticals. Transgenic plants expressing antigens from pathogenic microorganisms offer many advantages as low-cost production systems and effective delivery systems for vaccines. This new technology might contribute to global vaccine programs and might have a dramatic impact on health care in developing countries.
The phosphorylation state of the retinoblastoma (RB) protein in G0/G1 is dependent on growth status. (1991)

The product of the retinoblastoma gene (RB) is a nuclear phosphoprotein which is thought to regulate the proliferation of cells. Its phosphorylation state changes with passage through the cell cycle and it has been proposed that RB protein in its hypo-phosphorylated form prevents cells proliferating. We have investigated the phosphorylation state of the RB protein in an actively-dividing human B-lymphoblastoid cell line and after cell cycle arrest caused by alpha-Interferon (alpha-IFN). We show that the phosphorylation state of the RB protein in cells with 2N DNA content depends on whether the cells are actively cycling. Our data is compatible with the proposal that dephosphorylation of the RB protein allows cells to enter a quiescent state. This study sheds light on the molecular mechanisms which may mediate the cytostatic effects of alpha-IFN.
Synergy among antibacterial peptides and between peptides and small-molecule antibiotics (2010)

Antimicrobial peptides are key components of native immunity. Unlike most common small-molecule antibiotics, antimicrobial peptides have been refined by evolution to work synergistically within the host environment. The mechanisms of synergy are complex and specific, and it is only now that they are beginning to be understood. Thus, antimicrobial peptides are top candidates to broaden our limited therapeutic arsenal, and are very well suited to be used in synergic combinations with currently available antibiotics. In order for this promising strategy to become a reality, however, some key steps in basic and translational research need to be improved. These include the standardization and critical evaluation of testing and quantification methods, the characterization of the molecular mechanism of action, the study of indirect antibacterial activity such as immune-response modulation, and several other aspects that will be presented and discussed, with a focus primarily on antibacterial therapy. There will be a special focus on advances and innovations that might significantly improve the future perspectives of antimicrobial peptides from a therapeutic point-of-view.

Genetic and phenotypic diversity of autochthonous Saccharomyces spp. strains associated to natural fermentation of ‘Malvasia delle Lipari’ (2007)

Deeper insight on indigenous wine yeast of a conserved environment. The knowledge gained might offer a contribution to the selection of autochthonous wine yeast as starters for controlled fermentations.
Site-specific PEGylation of micro-plasmin for improved thrombolytic therapy through engineering enhanced resistance against serpin mediated inhibition (2019)

The relatively rapid inhibition of microplasmin by α2-AP leads to short functional half-life of the molecule in vivo, causing inefficient clot dissolution, even after site-specific, local catheter-based delivery. Here, we describe a PEGylation approach for improving the therapeutic potential via improving the survival of microplasmin in presence of its cognate inhibitor, α2-AP, wherein a series of strategically designed cysteine analogs of micro-plasminogen were prepared and expressed in E. coli, and further modified by covalent grafting in vitro with PEG groups of different molecular sizes so as to select single or double PEG chains that increase the molecular weight and hydrodynamic radii of the conjugates, but with a minimal discernible effect on intrinsic plasmin activity and structural framework, as explored by amidolytic activity and CD-spectroscopy, respectively. Interestingly, some of the purified PEG-coupled proteins after conversion to their corresponding proteolytically active forms were found to exhibit significantly reduced inhibition rates (up to 2-fold) by α2-AP relative to that observed with wild-type microplasmin. These results indicate an interesting, and not often observed, effect of PEG groups through reduced/altered dynamics between protease and inhibitor, likely through a steric hindrance mechanism. Thus, the present study successfully identifies single- and double-site PEGylated muteins of microplasmin with significantly enhanced functional half-life through enhanced resistance to inactivation by its in vivo plasma inhibitor. Such an increased survival of bioactivity in situ, holds unmistakable potential for therapeutic exploitation, especially in ischemic strokes where a direct, catheter-based deposition within the cranium has been shown to be promising, but is currently limited by the very short in vivo bioactive half-life of the fibrin dissolving agent/s.
Downlink SDMA for IEEE 802.11A/G: A Means for Improving Legacy Mobile Throughput Using a Multi-Antenna Access Point (2006)

We address the problem of downlink throughput improvement for IEEE 802.11a/g systems by using a modified access point (AP) equipped with multiple antennas. The main restriction is that the standard terminals should not be modified in any way. An alternating time-offset space division multiple access (SDMA) solution is considered for a conference room scenario. A simulation is based on channel models approved by the IEEE 802.11 Standard Group and takes into account the main features of the IEEE 802.11a/g standard. It is demonstrated that a near doubling of downlink capacity can be achieved in a conference room environment.
Acute Toxicity and Primary Irritancy of 2-Amino-3,5-Dicyano-4-0-Chlorophenyl-6-Ethoxypyridine (1985)

2-Amino-3,5-dicyano-4-o-chlorophenyl-6-ethoxypyridine (ACCPE) is a water soluble compound formed during the alkaline treatment of the alcoholic liquor in the production of 2-chlorobenzylidene malononitrile (CS). The acute toxicity and primary irritancy of ACCPE and CS were investigated and compared. Both perorally and intravenously, ACCPE was significantly less acutely toxic than CS. Also, whilst CS was a moderate dermal and eye irritant, ACCPE was not a primary skin irritant and only marginally irritating to the eye. ACCPE presents a significantly lower acute handling hazard than does CS.
