Rethinking offload: How to intelligently combine WiFi and small cells? (2013)

As future small cell base stations (SCBSs) are set to be multi-mode capable (i.e., transmitting on both licensed and unlicensed bands), a cost-effective integration of both technologies coping with peak data demands is crucial. Using tools from reinforcement learning, a distributed cross-system traffic steering framework is proposed whereby SCBSs leverage WiFi, to autonomously optimize their long-term performance over the licensed spectrum band, as a function of the traffic load and users' heterogeneous Quality of Service (QoS) requirements. The proposed traffic steering solution is validated in a Long-Term Evolution (LTE) simulator augmented with WiFi hotspots. Remarkably, it is shown that the proposed cross-system learning-based approach outperforms several benchmark algorithms and traffic steering policies, with gains reaching up to 200% when using a traffic-aware scheduler as compared to the classical proportional fair (PF) scheduler.
Ionization within a Cylindrical Capacitor:  Electrospray without an Externally Applied High Voltage (1998)

An interface was developed for mass spectrometry based on dc induction. Ions were produced as liquid flowed through a concentric cylindrical capacitor at room temperature. No externally applied high voltages affecting the spray tip were used, thus eliminating corona discharge problems in negative ion mode. The voltages applied to the capacitor were lower than those used for electrospray on the same instrument. Stable signals were observed for positive ions infused at flow rates from 50 nL/min to 200 μL/min, anions in the range 50−500 nL/min, without addition of sheath liquid or gas. The minimum concentration required to generate an interpretable product ion spectrum from the [M − 2H]2- precursor, for infused Salmonella typhimurium diphosphorylated lipid A, was improved by a factor of ∼500. Positive ion capillary LC/MS results for a horse apomyoglobin tryptic digest were similar to those observed for an optimized electrospray interface. Factor XIII b subunit, an 83-kDa protein, yielded an interpretable positive ion multiple charge envelope, under buffer conditions that did not allow collection of useful data with our low-flow electrospray source. Mass spectra were also generated for a single-stranded DNA 15-mer and 2‘,4‘-dideuteriotrifluoropropranolol, a small molecule that had been difficult to ionize by either electrospray or APCI.

The EGF receptor is required for efficient liver regeneration (2007)

Mice lacking the EGF receptor (EGFR) die between midgestation and postnatal day 20 with various defects in neural and epithelial organs. Here, we generated mice carrying a floxed EGFR allele to inactivate the EGFR in fetal and adult liver. Perinatal deletion of EGFR in hepatocytes resulted in decreased body weight, whereas deletion in the adult liver did not affect body mass. Although liver function was not affected, after partial hepatectomy mice lacking EGFR in the liver showed increased mortality accompanied by increased levels of serum transaminases indicating liver damage. Liver regeneration was delayed in the mutants because of reduced hepatocyte proliferation. Analysis of cell cycle progression in EGFR-deficient livers indicated a defective G(1)-S phase entry with delayed transcriptional activation and reduced protein expression of cyclin D1 followed by reduced cdk2 and cdk1 expression. Impaired liver regeneration was accompanied by compensatory up-regulation of TNFalpha in the serum and prolonged activation of c-Jun. Moreover, p38alpha and NF-kappaB activation was reduced in regenerating mutant livers, indicating an impaired stress response after hepatectomy. Our studies demonstrate that EGFR is a critical regulator of hepatocyte proliferation in the initial phases of liver regeneration.
Semi-Supervised Learning of Camera Motion from A Blurred Image (2018)

We address the problem of camera motion estimation from a single blurred image with the aid of deep convolutional neural networks. Unlike learning-based prior works that estimate a space-invariant blur kernel, we solve for the global camera motion which in turn represents the space-variant blur at each pixel. Leveraging the camera motion as well as the clean reference image during training, we resort to a semi -supervised training scheme that utilizes the strengths of both supervised and unsupervised learning to solve for the camera motion undergone by a space-variant blurred image. Finally, we show the effectiveness of such a motion estimation network with applications in space-variant deblurring and change detection.
Gluconeogenic Substrates and Hepatic Gluconeogenic Enzymes in Streptozotocin-Diabetic Rats: Effect of Mulberry ( <i>Morus indica</i> L.) Leaves (2007)

Mulberry (Morus indica L.) leaves, the sole food of the silk worm, were evaluated for antidiabetic effects in streptozotocin (STZ)-diabetic rats. Treatment with dried mulberry leaf powder at 25% of the diet for a period of 8 weeks was found to be remarkably beneficial to STZ-diabetic rats as evidenced by controlled hyperglycemia and glycosuria. In addition, mulberry leaves countered (reversed) the alterations in gluconeogenic substrates in STZ-diabetic rats as indicated by significant reduction in serum pyruvic and lactic acid levels, a significant increase in proteins and a significant decrease in free amino acid, urea, and creatinine levels in blood, and a decreased urinary excretion of urea and creatinine. Anomalies in the activities of hepatic gluconeogenic enzymes associated with impaired glucose homeostasis in STZ-diabetic rats were ameliorated by feeding the mulberry leaf-supplemented diet, indicating that control over hyperglycemia and associated complications in the diabetic state by mulberry leaves is by way of regulation of gluconeogenesis. With respect to all the parameters, mulberry leaves were more effective than the oral hypoglycemic drug glibenclamide.
A technique for translating states between database schemata (1982)

Consider two database schemata modeling the same reality. Given a state of the first schema, we can ask what information it provides about the state of the second schema. It turns out that this information can be represented by a table similar to a tableau of Aho, Sagiv and Ullman. We show a simple method to construct this table, by using results developed for tables of this type in the context of representing incomplete information in relational databases. We also consider a closely related notion of equivalence of database schemata, briefly sketching a method to test two schemata for equivalence.

Near infrared optical tomographic imaging of fluid containing tissues (2003)

In recent years near-infrared optical tomographic imaging (OTI) has made big strides towards becoming a clinically relevant medical imaging modality. Imaging of dynamic changes in blood parameters, functional brain imaging, and breast imaging are the most advanced areas of application of this novel technique. In this study we focus on difficulties that are encountered when OTI is employed for imaging tissues that contain fluid-filled regions. Examples of such tissues are the brain, which contains low scattering cerebrospinal fluids, joints, which enclose translucent synovial fluids, and the maternal abdomen, which is filled with amniotic fluid. In these cases widely accepted image reconstruction schemes that rely on the diffusion approximation have limited applicability, and more advanced model-based iterative image reconstructions methods that make use of the equation of radiative transfer promise more accurate results.
A kurtosis-based blind separation of sources using the Cayley transform (2002)

This paper proposes a new kurtosis-based method for blind separation of sources. For instantaneous mixture of sources, the conventional kurtosis-based approaches provide an elegant solution, where separation is made by minimizing or maximizing certain contrast functions with respect to an orthogonal matrix representing the separator. In the case of a convolutive mixture, however the class of orthogonal matrices need to be extended to that of para-unitary matrices, and its treatment becomes cumbersome. In this paper the problem is overcome by introducing the Cayley transform, which transforms a para-unitary matrix to a para-skew-Hermitian matrix. The fact that the set of para-skew-Hermitian matrices is a vector space offers a relatively simple method for kurtosis-based blind separation of convolutively mixed signals.
Optimization for visible light photocatalytic water splitting: gold-coated and surface-textured TiO2 inverse opal nano-networks (2013)

A gold nanoparticle-coated and surface-textured TiO2 inverse opal (Au/st-TIO) structure that provides a dramatic improvement of photoelectrochemical hydrogen generation has been fabricated by nano-patterning of TiO2 precursors on TiO2 inverse opal (TIO) and subsequent deposition of gold NPs. The surface-textured TiO2 inverse opal (st-TIO) maximizes the photon trapping effects triggered by the large dimensions of the structure while maintaining the adequate surface area achieved by the small dimensions of the structure. Au NPs are incorporated to further improve photoconversion efficiency in the visible region via surface plasmon resonance. st-TIO and Au/st-TIO exhibit a maximum photocurrent density of ∼0.58 mA cm(-2) and ∼0.8 mA cm(-2), which is 2.07 and 2.86 times higher than that of bare TIO, respectively, at an applied bias of +0.5 V versus an Ag/AgCl electrode under AM 1.5 G simulated sunlight illumination via a photocatalytic hydrogen generation reaction. The excellent performance of the surface plasmon-enhanced mesoporous st-TIO structure suggests that tailoring the nanostructure to proper dimensions, and thereby obtaining excellent light absorption, can maximize the efficiency of a variety of photoconversion devices.
Multi-frame estimation of planar motion (2000)

Traditional plane alignment techniques are typically performed between pairs of frames. We present a method for extending existing two-frame planar motion estimation techniques into a simultaneous multi-frame estimation, by exploiting multi-frame subspace constraints of planar surfaces. The paper has three main contributions: 1) we show that when the camera calibration does not change, the collection of all parametric image motions of a planar surface in the scene across multiple frames is embedded in a low dimensional linear subspace; 2) we show that the relative image motion of multiple planar surfaces across multiple frames is embedded in a yet lower dimensional linear subspace, even with varying camera calibration; and 3) we show how these multi-frame constraints can be incorporated into simultaneous multi-frame estimation of planar motion, without explicitly recovering any 3D information, or camera calibration. The resulting multi-frame estimation process is more constrained than the individual two-frame estimations, leading to more accurate alignment, even when applied to small image regions.
Single-Stage Semantic Segmentation From Image Labels (2020)

Recent years have seen a rapid growth in new approaches improving the accuracy of semantic segmentation in a weakly supervised setting, i.e. with only image-level labels available for training. However, this has come at the cost of increased model complexity and sophisticated multi-stage training procedures. This is in contrast to earlier work that used only a single stage -- training one segmentation network on image labels -- which was abandoned due to inferior segmentation accuracy. In this work, we first define three desirable properties of a weakly supervised method: local consistency, semantic fidelity, and completeness. Using these properties as guidelines, we then develop a segmentation-based network model and a self-supervised training scheme to train for semantic masks from image-level annotations in a single stage. We show that despite its simplicity, our method achieves results that are competitive with significantly more complex pipelines, substantially outperforming earlier single-stage methods.
Image reconstruction using eigenfunctions of a scattering operator (2006)

A multiple-frequency iterative inverse scattering method is reviewed. In the method, scattered acoustic fields are described using a scattering operator with eigenfunctions that correspond to far-field patterns of an effective source distribution. Incident-wave patterns determined using the eigenfunctions focus on the distribution. The focusing properties of the eigenfunctions are employed to reconstruct an object by using products of numerically calculated fields defined by weighted products of the eigenfunctions. The full range of frequencies present in an incident pulse waveform is employed. Iteration using a linearized version of the method and calculated scattering from an estimate of the object permits reconstruction of large-scale high-contrast objects. The method is illustrated using calculated and measured data. In the calculations, an exact solution for scattering from nonconcentric lossy cylinders with parallel axes was employed to obtain the scattered field. In the measurements, a novel ring-transducer system was used to obtain the incident and total fields. The results of simulations and experiments show that the method converges and is accurate for high-contrast large-scale tissue-mimicking objects. Reconstructions using measured scattering from random media have considerably less speckle than conventional b-scan images, implying that the inverse scattering method can clearly demonstrate small high-contrast inclusions.
Broadband visible wavelength high efficiency meta-gratings (2016)

Serum From Patients With Acute Coronary Syndromes Displays a Proapoptotic Effect on Human Endothelial Cells (2003)

Physical-Layer Algebraic Network Coding and Superposition Coding for the Multi-Source Cooperation Aided Uplink (2009)

In this paper, we consider coding schemes designed for energy efficient multi-source cooperation. More explicitly, we propose both a powerful superposition coding scheme and a physical-layer algebraic network coding scheme. The concept of generalised network coding is introduced and the relation between superposition coding and network coding is revealed. Our simulation results demonstrate that both of the proposed schemes are capable of performing close to the outage probability bound at the lower end of the target transmit power range. Moreover, compared to the superposition coding scheme considered, the proposed algebraic network coding arrangement imposes a lower complexity at the cost of a slight performance degradation, while maintaining the same throughput and delay.
Cathelicidins: family of antimicrobial peptides. A review (2012)

Cathelicidins are small, cationic, antimicrobial peptides found in humans and other species, including farm animals (cattle, horses, pigs, sheep, goats, chickens, rabbits and in some species of fish). These proteolytically activated peptides are part of the innate immune system of many vertebrates. These peptides show a broad spectrum of antimicrobial activity against bacteria, enveloped viruses and fungi. Apart from exerting direct antimicrobial effects, cathelicidins can also trigger specific defense responses in the host. Their roles in various pathophysiological conditions have been studied in mice and humans, but there are limited information about their expression sites and activities in livestock. The aim of the present review is to summarize current information about these antimicrobial peptides in farm animals, highlighting peptide expression sites, activities, and future applications for human and veterinary medicine.
Shock-induced melting and rapid solidification (1987)

Model calculations are presented to estimate that approx.50 GPa is required to completely shock melt metal powders with quenching at rates up to 10/sup 8/ K/s. Experiments are discussed for powders of a Cu-Zr alloy compacted in the usual way at 16 GPa and melted by shocking to 60 GPa. 12 refs.
Tablet disintegrant activities of new starch from immature pepino fruits (2011)

A new starch powder isolated by steeping process from pepino fruits(Solanum muricatum Aiton) as tablet disintegrant was compared with maize starch BP (MS) in paracetamol tablets prepared via wet granulation method. Increasing concentration resulted in slight increase in hardness and decrease in friability for MS, whereas hardness slightly decreased and friability marginally increased for PS. PS absorbed least moisture followed by MS. PS formulations showed longer disintegration time than
MS.However disintegration time was comparable at
10 % w/w concentration: PS , 4.7; and MS , 5.0 min.
PS is likely to initiate disintegration by swelling and capillary action. Drug dissolution (70%) was within 30 min. Thus PS powder appears to be a suitable substitute for MS as internal disintegrant in paracetamol tablet formulations.
Characterization of estrogenicity of phytoestrogens in an endometrial-derived experimental model. (1998)

Severe developmental and reproductive disorders in wild animals have been linked to high exposure to persistent environmental chemicals with hormonal activity. These adverse effects of environmental estrogens have raised considerable concern and have received increasing attention. Although numerous chemicals with the capacity to interfere with the estrogen receptor (ER) have been identified, information on their molecular mechanism of action and their relative potency is rather limited. For the endometrium, the lack of information is due to the lack of a suitable experimental model. We investigated the functions of phytoestrogens in an endometrial-derived model, RUCA-I rat endometrial adenocarcinoma cells. The cells were cultured on a reconstituted basement membrane to preserve their functional differentiation and estrogen responsiveness. We assessed the relative binding affinity to the estrogen receptor of the selected phytoestrogens coumestrol, genistein, daidzein, and the putative phytoestrogen mangostin compared to estradiol by a competitive Scatchard analysis. The following affinity ranking was measured: 17beta-estradiol >>> coumestrol > genistein > daidzein >>> mangostin. In addition, we investigated the capacity of these compounds to promote the increased production of complement C3, a well-known estradiol-regulated protein of the rat endometrium. All substances tested increased the production of complement C3, although different concentrations were necessary to achieve equivalent levels of induction compared to estradiol. Mechanistically we were able to demonstrate that the increase of complement C3 production was mediated by primarily increasing its steady-state mRNA level. These findings indicate that RUCA-I cells represent a sensitive model system to elucidate relative potencies and functions of environmental estrogens in an endometrium-derived model.
Synthesis of Some Fluorinated Heteroannulated Pyrimidines - Purine Isosteres - via Inverse-Electron-Demand Diels-Alder Protocol (2009)

The inverse-electron-demand Diels-Alder reaction of electron excessive systems such as enamines, electron-enriched amino heterocycles, and anilines with 2,4,6-tris(polyfluoroalkyl)-1,3,5-triazines was investigated. This study results in the synthesis of a set of polyfluoroalkyl containing pyrimidines, heteroannulated pyrimidines, and quinazolines. Following the elaborated synthetic pathway, l-(β-d-ribofuranosyl)-4,6-bis(polyfluoroalkyl)-1H-pyrazolo[3,4-d]pyrimidines were prepared starting from iso-AIRs.
MicroRNA-200c Represses Migration and Invasion of Breast Cancer Cells by Targeting Actin-Regulatory Proteins FHOD1 and PPM1F (2011)

MicroRNA-200c (miR-200c) has been shown to suppress epithelial-mesenchymal transition (EMT), which is attributed mainly to targeting of ZEB1/ZEB2, repressors of the cell-cell contact protein E-cadherin. Here we demonstrated that modulation of miR-200c in breast cancer cells regulates cell migration, cell elongation, and transforming growth factor β (TGF-β)-induced stress fiber formation by impacting the reorganization of cytoskeleton that is independent of the ZEB/E-cadherin axis. We identified FHOD1 and PPM1F, direct regulators of the actin cytoskeleton, as novel targets of miR-200c. Remarkably, expression levels of FHOD1 and PPM1F were inversely correlated with the level of miR-200c in breast cancer cell lines, breast cancer patient samples, and 58 cancer cell lines of various origins. Furthermore, individual knockdown/overexpression of these target genes phenocopied the effects of miR-200c overexpression/inhibition on cell elongation, stress fiber formation, migration, and invasion. Mechanistically, targeting of FHOD1 by miR-200c resulted in decreased expression and transcriptional activity of serum response factor (SRF), mediated by interference with the translocation of the SRF coactivator mycocardin-related transcription factor A (MRTF-A). This finally led to downregulation of the expression and phosphorylation of the SRF target myosin light chain 2 (MLC2) gene, required for stress fiber formation and contractility. Thus, miR-200c impacts on metastasis by regulating several EMT-related processes, including a novel mechanism involving the direct targeting of actin-regulatory proteins.
Scalable Synthesis of Lissamine Rhodamine B Sulfonyl Chloride and Incorporation of Xanthene Derivatives onto Polymer Supports (2008)

A scalable synthetic route to lissamine rhodamine B sulfonyl chloride has been developed and a series of monomeric derivatives of this xanthene dye have been synthesized. Their subsequent incorporation into polymer supports has been accomplished and led to improved thermal stability for the conjugates as compared to the free dye.
