MIMO adaptive codebook for cross-polarized antenna arrays (2013)

In this paper we address the design of MIMO double codebook structure for cross-polarized antenna arrays. Double codebooks consist of two codebook components, a wide-band long-term component and a short-term sub-band component. Herein we study particularly the two layer short-term sub-band component and provide the complete set of structure types leading to orthogonal constant modulus codewords and cross-polarization phase of M-PSK alphabet. By 3GPP LTE system simulations we show that a novel, two layer structure type, provides significant improvements in channels with large angular spreads.
In vivo and in vitro testing with rAni s 1 can facilitate diagnosis of Anisakis simplex allergy. (2014)

rAni s 1 is recognized by 100% of our patients and is able to distinguish between patients allergic to A simplex and patients with acute urticaria who are sensitized to A simplex but have no clinical history of allergy to this parasite.
Interleukin‐8 production by the human colon epithelial cell line HT‐29: modulation by interleukin‐13 (1996)

We have determined which cytokines induce and modulate the production of the chemokine interleukin‐8 (IL‐8) by the human colonic epithelial cell line HT‐29. Growth arrested cell cultures were stimulated with the human recombinant cytokines interleukin‐1α (IL‐1α), tumour necrosis factor‐α (TNF‐α), interferon‐γ (IFN‐γ), interleukin‐13 (IL‐13), interleukin‐10 (IL‐10) or vehicle added alone or in combination. The production of IL‐8 was determined by enzyme‐linked immunosorbent assay (ELISA) and IL‐8 messenger RNA expression by Northern blot analysis. The production of IL‐8 in unstimulated cells was undetectable by both ELISA and Northern blot analysis. HT‐29 cells produced IL‐8 following stimulation with IL‐1α or TNF‐α in a time‐ and a concentration‐dependent manner, while IFN‐γ, IL‐10 and IL‐13 did not induce IL‐8 production by HT‐29 cells. IL‐13 was found to up‐regulate significantly ( P &lt; 0.01) the IL‐1α but not the TNF‐α‐induced IL‐8 generation by HT‐29 cells. In contrast, IL‐10 had no effect on either IL‐1α or TNF‐α‐induced IL‐8 production. Experiments using cycloheximide demonstrated that this synergistic effect of IL‐13 and IL‐1α on IL‐8 secretion was not through de novo protein synthesis. Using actinomycin‐D, we demonstrated that the IL‐13 up‐regulation was at the level of transcription rather than messenger RNA stability. These findings suggest that colonic epithelial cells have a functional IL‐13 receptor, which is coupled to an up‐regulation of IL‐1α, but not TNF‐α induced IL‐8 generation.
Targeting Transferrin Receptor to Transport Antisense Oligonucleotides Across the Blood-Brain Barrier (2023)

Abstract Antisense oligonucleotides (ASO) are promising therapies for neurological disorders, though they are unable to cross the blood-brain barrier (BBB) and must be delivered directly to the central nervous system (CNS). Here, we use a human transferrin receptor (TfR)-binding molecule to transport ASO across the BBB in mice and non-human primates, termed oligonucleotide transport vehicle (OTV). Systemically delivered OTV drives significant, cumulative, and sustained knockdown of the ASO target across multiple CNS regions and all major cell types. Further, systemic OTV delivery enables more uniform ASO biodistribution and knockdown compared to two other clinically relevant ASO delivery routes: a standard, high affinity TfR antibody, or direct ASO delivery to the CSF. Together, our data support systemically delivered OTV as a potential therapeutic platform for neurological disorders. One-Sentence Summary Systemically dosed OTV delivered via TfR1 targeting shows widespread and cumulative target knockdown in the mouse and NHP CNS.
On the correctness of orphan management algorithms (1992)

In a distributed system, node failures, network delays, and other unpredictable occurences can result in orphan computations—subcomputations that continue to run but whose results are no longer needed. Several algorithms have been proposed to prevent such computations from seeing inconsistent states of the shared data. In this paper, two such orphan management algorithms are analyzed. The first is an algorithm implemented in the Argus distributed-computing system at MIT, and the second is an algorithm proposed at Carnegie-Mellon. The algorithms are described formally, and complete proofs of their correctness are given. The proofs show that the fundamental concepts underlying the two algorithms are very similar in that each can be regarded as an implementation of the same high-level algorithm. By exploiting properties of information flow within transaction management systems, the algorithms ensure that orphans only see states of the shared data that they could also see if they were not orphans. When the algorithms are used in combination with any correct concurrency control algorithm, they guarantee that all computations, orphan as well as nonorphan, see consistent states of the shared data.
Online Dictionary Learning Aided Target Recognition In Cognitive GPR (2017)

Sparse decomposition of ground penetration radar (GPR) signals facilitates the use of compressed sensing techniques for faster data acquisition and enhanced feature extraction for target classification. In this paper, we investigate the application of an online dictionary learning (ODL) technique in the context of GPR to bring down the learning time as well as improve identification of abandoned anti-personnel landmines. Our experimental results using real data from an L-band GPR for PMN/PMA2, ERA and T72 mines show that ODL reduces learning time by 94\% and increases clutter detection by 10\% over the classical K-SVD algorithm. Moreover, the proposed methodology could be helpful in cognitive operation of the GPR where the system adapts the range sampling based on the learned dictionary.
Address sequences with improved resynchronization capability (2002)

The author examines the resynchronization properties of the frequency-hopping address sequences that have been proposed as an alternative to the Reed-Solomon address sequences. It is shown that the new address sequences have been better resynchronization properties than the corresponding Reed-Solomon address sequences. The author has also derived an expression for the exact number of the new address sequences and shown that it is very close to the theoretical limit.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Controlling Semiconductor/Metal Junction Barriers by Incomplete, Nonideal Molecular Monolayers (2006)

We study how partial monolayers of molecular dipoles at semiconductor/metal interfaces can affect electrical transport across these interfaces, using a series of molecules with systematically varying dipole moment, adsorbed on n-GaAs, prior to Au or Pd metal contact deposition, by indirect evaporation or as "ready-made" pads. From analyses of the molecularly modified surfaces, we find that molecular coverage is poorer on low- than on high-doped n-GaAs. Electrical charge transport across the resulting interfaces was studied by current-voltage-temperature, internal photoemission, and capacitance-voltage measurements. The data were analyzed and compared with numerical simulations of interfaces that present inhomogeneous barriers for electron transport across them. For high-doped GaAs, we confirm that only the former, molecular dipole-dependent barrier is found. Although no clear molecular effects appear to exist with low-doped n-GaAs, those data are well explained by two coexisting barriers for electron transport, one with clear systematic dependence on molecular dipole (molecule-controlled regions) and a constant one (molecule-free regions, pinholes). This explains why directly observable molecular control over the barrier height is found with high-doped GaAs: there, the monolayer pinholes are small enough for their electronic effect not to be felt (they are "pinched off"). We conclude that molecules can control and tailor electronic devices need not form high-quality monolayers, bind chemically to both electrodes, or form multilayers to achieve complete surface coverage. Furthermore, the problem of stability during electron transport is significantly alleviated with molecular control via partial molecule coverage, as most current flows now between, rather than via, the molecules.
Enhanced Antibody Formation by Partial Hepatectomy (1969)

Antibody formation was significantly enhanced by partial hepatectomy, performed 5 or 20 days after antigenic stimulation. On the other hand, little effect of partial hepatectomy on antibody formation was observed in rats operated 5 days before immunization or in sham-operated rats. The incorporation of 3H-leucinc into ribosomal fractions of splenic and lymph node cells was increased one day after partial hepatectomy. The incorporation of 3H-leucine into specific antibody molecule was elevated in two days after the operation.
Enhanced gene expression plasticity as a mechanism of adaptation to a variable environment in a reef-building coral (2016)

Local adaptation is ubiquitous, but the molecular mechanisms giving rise to this ecological phenomenon remain largely unknown. A year-long reciprocal transplant of mustard hill coral (Porites astreoides) between a highly environmentally variable inshore habitat and more stable offshore habitat demonstrated that both inshore and offshore populations exhibit elevated growth, protein and lipid content in their home reef environment, indicative of local adaptation. Here, we characterized the genomic basis of this adaptation in both coral hosts and their intracellular algal symbionts (Symbiodinium sp.) using genome-wide gene expression profiling and gene coexpression network analysis. Inshore and offshore coral populations differ primarily in their capacity for gene expression plasticity: upon transplantation to a novel environment inshore corals were able to match expression profiles of the local population significantly better than offshore corals. Furthermore, elevated plasticity in expression of environmental stress response (ESR) genes was adaptive in the inshore environment: it correlated with the least susceptibility to a natural summer bleaching event, whereas higher constitutive ESR gene expression (frontloading sensu Barshis et al. 2013) did not. Our results reveal a novel genomic mechanism of resilience to a variable environment, demonstrating that corals are capable of a more diverse molecular response to environmental stress than previously thought.

Finding the Most Catalytically Active Platinum Clusters With Low Atomicity (2015)

Abstract On a subnanometer scale, an only one‐atom difference in a metal cluster may cause significant transitions in the catalytic activity due to the electronic and geometric configurations. We now report the atomicity‐specific catalytic activity of platinum clusters with significantly small atomicity, especially below 20. The atomic coordination structure is completely different from that of the larger face‐centered cubic ( fcc ) nanocrystals. Here, an electrochemical study on such small clusters, in which the atomicity ranged between 12 and 20, revealed Pt 19 as the most catalytically active species. In combination with a theoretical study, a common structure that leads to a high catalytic performance is proposed.

Conduction-band discontinuities of InxAl1−xAs/In0.53Ga0.47As n-isotype heterojunctions (1990)

The conduction-band offsets ΔEc of n-isotype InxAl1−xAs/In0.53Ga0.47As heterojunctions, with 0.47&amp;lt;x≤0.52, grown by molecular-beam epitaxy, lattice matched and pseudomorphically strained on n+-InP substrates, were determined from the capacitance-voltage profiling technique. A more accurate ΔEc value was obtained after the correction for fixed interface charge perturbation. The ΔEc related to the band-gap difference ΔEgs of the heterojunction are found to be ΔEc=0.70ΔEgs. The fixed interface charges are acceptorlike with a density of the order 1010/cm2.
3D pose estimation in high dimensional search spaces with local memorization (2010)

In this paper, a stochastic approach for extracting the articulated 3D human postures by synchronized multiple cameras in the high-dimensional configuration spaces is presented. Annealed Particle Filtering (APF) [1] seeks for the globally optimal solution of the likelihood. We improve and extend the APF with local memorization to estimate the suited kinematic postures for a volume sequence directly instead of projecting a rough simplified body model to 2D images. Our method guides the particles to the global optimization on the basis of local constraints. A segmentation algorithm is performed on the volumetric models and the process is repeated. We assign the articulated models 42 degrees of freedom. The matching error is about 6% on average while tracking the posture between two neighboring frames.
Vestibular Habituation Training: Exercise Treatment for Vertigo Based upon the Habituation Effect (1989)

Vestibular habituation training is an exercise treatment for positional vertigo based on the assumption that such a type of vertigo can be cured by habituation effect. The latter is produced by repeating the situation eliciting vertigo. In this way the mechanisms of adaptation and compensation are stimulated, processes of which have been considered "error controlled." Clinical experience with the vestibular habituation training test battery (consisting of 19 maneuvers) showed that in each particular patient only a limited number of responses were positive in various combinations. Selecting the exercises is then a logical consequence. Followup showed a progressive reduction of the positive cases, as well as the number of positive maneuvers. This is in accordance with the development of compensation as it has been observed in experimental conditions and with the decline of progressive responses observed in habituation experiments.
A Novel Artificial Neural Network-Based Correlation for Evaluating the Rate of Penetration in a Natural Gas Bearing Sandstone Formation: A Case Study in a Middle East Oil Field (2022)

This study presented an empirical correlation to estimate the drilling rate of penetration (ROP) while drilling into a sandstone formation. The equation developed in this study was based on the artificial neural networks (ANN) which was learned to assess the ROP from the drilling mechanical parameters. The ANN model was trained on 630 datapoints collected from five different wells; the suggested equation was then tested on 270 datapoints from the same training wells and then validated on three other wells. The results showed that, for the training data, the learned ANN model predicted the ROP with an AAPE of 7.5%. The extracted equation was tested on data gathered from the same training wells where it estimated the ROP with AAPE of 8.1%. The equation was then validated on three wells, and it determined the ROP with AAPEs of 9.0%, 10.7%, and 8.9% in Well-A, Well-B, and Well-D, respectively. Compared with the available empirical equations, the equation developed in this study was most accurate in estimating the ROP.

Design Strategies for Branched and Highly Branched Macromolecular Architectures Using Nitroxide-Mediated Living Free-Radical Procedures (1998)

Free radical procedures play a dominant role in the synthesis of a wide variety of commodity polymers due to the mild, non-demanding reaction conditions and compatibility with numerous functional groups. However, one of the major disadvantages of free radical polymerizations is the lack of control over macromolecular structure. For example, the polymers obtained are frequently polydisperse and the technique provides poor control over molecular weight, chain ends, and architecture. Many of these shortcomings have recently been overcome using nitroxide mediated 'living' free radical procedures, coupled with well defined unimolecular alkoxyamine initiators. In this report, various strategies for the control of polymeric structure and macromolecular architecture using novel 'living' free radical procedures will be discussed and compared with currently available techniques.
Observation of linear solid-solid phase transformation in silicon nanoparticles (2012)

In bulk single-crystal silicon, the semiconducting diamond-to-metallic \ss{}-Sn phase transformation nucleates on defects, and is manifested by a sharp uptake in light absorption at a threshold of \ensuremath{\sim}11 Gpa, accompanied with the creation of nanosized (20--50 nm) fragmentation domains. We report on the observation of linear uptakes in the absorption and in the luminescence and with insignificant spectral change in ultrasmall 1-nm Si particles. We associate the gradual absorption uptake and luminescence yield with silicon-metal transformation on the surface. The insignificant change in the spectral content of the luminescence points to surface stability for particles, which are smaller than the bulk fragmentation domain. First-principles atomistic calculations yield absorption behavior that exhibits gradual uptake followed by sharp uptake at \ensuremath{\sim}9--11 Gpa. The results point to the conclusion that two-dimensional surface-like phase transformations are manifested by linear uptake in absorption and luminescence.
Modeling and optimization of vertical-cavity semiconductor laser amplifiers (2001)

We present detailed yet largely analytical models for gain, optical bandwidth, and saturation power of vertical-cavity laser amplifiers (VCLAs) in reflection and transmission mode. VCLAs are potential low-cost alternatives to in-plane laser amplifiers and they have the inherent advantage of polarization insensitivity, high fiber coupling efficiency, and low noise figure. Simple formulas for the optical gain-bandwidth product are derived which are valid for any type of Fabry-Perot amplifier. Our saturation model is based on rate equations for electrons and holes. It considers a sub-linear material gain, gain enhancement by the standing wave effect, Auger recombination, defect recombination, and spontaneous emission. Common linear approximations are avoided to correctly predict performance limits. Excellent agreement with measurements on novel 1.3-micron VCLAs is obtained. The models are used to analyze device performance and to investigate optimization options. With reduced top mirror reflectivity and increased pump efficiency, substantial and simultaneous improvements of optical bandwidth and saturation power are predicted without sacrificing gain. Parameter plots are given which allow for an easy exploration of the VCLA design space, matching desired performance goals with the required mirror reflectivity and pump current.
Inhibition of the human allogeneic mixed lymphocyte response by cyclosporin A: relationship with the IL‐12 pathway (1996)

Interleukin-12 (IL-12) is an important cytokine in the control of cell-mediated immunity. We have previously shown that endogenous IL-12 plays a role in the development of human allogeneic response. In the present study, we investigated the relationship between Cyclosporin A (CsA)-inhibitory effect and IL-12 pathway during human alloreaction in vitro. CsA addition at the sensitizing phase of primary mixed lymphocyte reaction (MLR) resulted in the inhibition of both p40 and p70 IL-12 production in a dose-dependent manner. In contrast, CsA had no effect on IL-12-receptor beta 1 chain (IL-12 R beta 1) expression in T cells induced upon allogeneic activation. Addition of exogenous IL-12 significantly restored CsA-inhibited alloreactive cytotoxic T lymphocyte (CTL) generation and had a marginal effect on T cell proliferative response. The IL-12-induced restoration of CTL generation was IFN gamma-mediated, as it was significantly altered when anti-IFN gamma was added. The restoration of CTL activity by exogenous IL-12 correlated with the capacity of this cytokine to partially restore granzyme B mRNA expression in alloreactive CTL. This study indicates that inhibition of IL-12 production is a novel additional mechanism for the inhibitory effect of CsA on the development of human allogeneic cytotoxic response.
Antitubercular drug discovery: the molecular modification as promise tool (2012)

Tuberculosis is a chronic infectious disease caused by etiologic agent Mycobacterium tuberculosis. "It has been reported that rates of incidence is increasing and each year around 8.9-9.9 million new cases are detected”. The current TB therapy presents several problems such as long-term therapy, drug resistance, no-compliance to therapy and few therapeutic sources to treat the disease. The discovery of new drugs safer and more efficient is urgent. The molecular modification is an important tool that allows discovering new compounds that can be win these challenges. In this work, we summarize the main strategies useful to obtain a new antitubercular drug.
