Exciton Polarization and Renormalization Effect for Optical Modulation in Monolayer Semiconductors (2019)

The ideal quantum confinement structure of monolayer semiconductors offers prominent optical modulation capabilities that are mediated by enhanced many-body interactions. Herein, we establish an electrolyte-gating method for tuning the luminescence properties that are in transition metal dichalcogenide (TMDC) monolayers. We fabricate electric double-layer capacitors on TMDC/graphite heterostructures to investigate electric-field- and carrier-density-dependent photoluminescence. The exciton peak energy initially shows a slight quadratic red shift of ∼1 meV without carrier accumulations, which is caused by the quantum-confined Stark effect. In contrast, the exciton resonance exhibits a larger red shift up to 10 meV with the accumulated carrier density above 10<sup>13</sup> cm<sup>-2</sup>. These results indicate that the optical transitions can be largely modulated by the carrier density control in S- and Se-based TMDCs, as triggered by the doping-induced band gap renormalization effect. To further inspire this modulation capability, we also apply our method to electrolyte-based TMDC light-emitting devices. Biasing solely in electrolyte-induced p-i-n junctions yields pronounced red shifts up to 40 meV for exciton and trion electroluminescence. Consequently, our approach reveals that the doping effects in the high-carrier-density regimes are potentially significant for efficient optical modulation in monolayer semiconductors.
Cyclo[2]benzimidazole: luminescence turn-on sensing of anions (2011)

Cyclo[2]benzimidazole is a new host for anions that turns on its luminescence up to 150 fold upon binding. Photoexcited cyclo[2]benzimidazole undergoes an efficient non-radiative deactivation through an excited-state intramolecular proton-transfer (ESIPT) mechanism. Upon binding an anion, the ESIPT pathway is blocked, resulting in an increase in the luminescence efficiency.
Anterior-Only Stabilization of Three-Column Thoracolumbar Injuries (2005)

Current types of anterior spinal instrumentation and reconstruction techniques can allow some types of unstable three-column thoracolumbar injuries to be treated in an anterior stand-alone fashion. This allows direct anterior decompression of neural elements, improvement in segmental angulation, and acceptable rates of arthrodesis without the need for supplemental posterior instrumentation.
Enabling RAN Slicing Through Carrier Aggregation in mmWave Cellular\n Networks (2020)

The ever increasing number of connected devices and of new and heterogeneous\nmobile use cases implies that 5G cellular systems will face demanding technical\nchallenges. For example, Ultra-Reliable Low-Latency Communication (URLLC) and\nenhanced Mobile Broadband (eMBB) scenarios present orthogonal Quality of\nService (QoS) requirements that 5G aims to satisfy with a unified Radio Access\nNetwork (RAN) design. Network slicing and mmWave communications have been\nidentified as possible enablers for 5G. They provide, respectively, the\nnecessary scalability and flexibility to adapt the network to each specific use\ncase environment, and low latency and multi-gigabit-per-second wireless links,\nwhich tap into a vast, currently unused portion of the spectrum. The\noptimization and integration of these technologies is still an open research\nchallenge, which requires innovations at different layers of the protocol\nstack. This paper proposes to combine them in a RAN slicing framework for\nmmWaves, based on carrier aggregation. Notably, we introduce MilliSlice, a\ncross-carrier scheduling policy that exploits the diversity of the carriers and\nmaximizes their utilization, thus simultaneously guaranteeing high throughput\nfor the eMBB slices and low latency and high reliability for the URLLC flows.\n
Identification of adenovirus genes that require template replication for expression (1983)

The relationship between adenovirus type 2 DNA replication and expression of intermediate stage viral genes was investigated. The 1.03-kilobase mRNA from early region 1b (E1b) and the mRNAs coding for proteins IX and IVa2 were first detected between 6 and 8 h postinfection. Inhibition of viral DNA replication with hydroxyurea prevented expression of the IX and IVa2 mRNAs, but not of the E1b mRNA. Pulse-labeling experiments demonstrated that the block of IX and IVa2 expression in hydroxyurea-treated cells was at the level of transcription. By a series of superinfection experiments, it was determined that the viral and cellular factors present during the late stage of adenovirus infection are insufficient to activate IX gene expression. The viral DNA template must first replicate before IX transcription can begin.
M1 PROTEIN FROM STREPTOCOCCUS PYOGENES INDUCES NITRIC OXIDE-MEDIATED VASCULAR HYPORESPONSIVENESS TO PHENYLEPHRINE (2010)

Streptococcus pyogenes carrying M1 protein causes the severe and increasingly prevalent streptococcal toxic shock syndrome and necrotizing fasciitis. M1 protein is an important virulence factor of S. pyogenes and induces an inflammatory response in human monocytes. We wanted to investigate if purified M1 protein in solution could induce vascular NO production leading to vasopressor hyporesponsiveness. Rat aortic segments were incubated with M1 protein or LPS in vitro. M1 protein (10 microg mL) and LPS (1 ng mL) to a similar extent induced NO production and hyporesponsiveness to the vasoconstrictor phenylephrine. Immunogold electron microscopy demonstrated that M1 protein binds to Toll-like receptor 2 (TLR2) as well as TLR4 in mouse aorta but only to TLR2 in human omental artery. Incubation with M1 protein caused a reduction in the contractile response to phenylephrine in aortic segments from wild-type and TLR2-knockout but not from TLR4-knockout mice. In conclusion, M1 protein causes vascular NO production leading to hyporesponsiveness to vasopressors via a mechanism involving TLR, but the subtypes may be species dependent. M1 protein could contribute to the circulatory disturbances accompanying severe invasive streptococcal infections.
&lt;title&gt;Hybrid knowledge bases for integrating symbolic, numeric, and image data&lt;/title&gt; (1995)

A hybrid knowledge base (HKB), due to Nerode and Subrahmanian, is a formalism that provides a uniform theoretical framework within which heterogeneous data representation paradigms may be integrated. The HKB framework is broad enough to support the integration of a wide array of databases including, but not restricted to: relational data (with multiple schemas), spatial data structures (including different kinds of quadtrees), pictorial data (including GIF files), numeric data and computations (e.g., linear and integer programming), and terrain data. In this paper, we focus on how the HKB paradigm can be used as a unifying framework to reason about terrain data in the context of background data that may be contained in relational and spatial data structures. We show how the current implementation of the HKB compiler can support such an integration scheme.
Identification of small molecules uncoupling the Notch::Jagged interaction through an integrated high-throughput screening (2017)

Notch signaling plays an important role in several cellular functions including growth, differentiation, cell fate determination and stemness. Increased Notch activity has been linked to several types of cancers. Activation of Notch signaling is triggered by the interaction of Notch receptors (Notch1-4) with 5 different ligands (Jagged1-2 and Dll1-3-4) expressed on the neighbouring cells. Currently, indirect approaches to inhibit Notch signalling are based on the inhibition of the key step of Notch activation catalyzed by the γ-Secretase and thereby affect several different γ-Secretase substrates; conversely direct strategies get advantage of antibody-based drugs. The evidence that Jagged-mediated Notch activation plays a key role in cancer cell biology and the interplay with the surrounding microenvironment prompted us to develop a strategy to directly inhibit Notch activation by uncoupling its interaction with the Jagged, using an unprecedented approach based on small molecules. We set-up a screening strategy based on: protein::protein docking of crystallographic structures of Notch1 with Jagged1; comparative modelling of the Notch2:Jagged2 complex, based on the Notch1::Jagged1 complex; in silico high-throughput screening directed to Notch2 interaction surface of a virtual chemical library containing a large variety of molecules commercially available. The predicted pharmacological activity of the selected compounds was validated in vitro by a gene reporter and a viability assay. This approach led to the successful identification of two candidates with different anti-proliferative potency and efficacy. This represents the first step towards the rational identification of candidate molecules for the development of entirely novel drugs directed to inhibit Notch signaling in cancer.

K-CL co-transport plays an important role in normal and   thalassemic erythropoiesis (2007)

Ineffective erythropoiesis of in vitro cultured beta-thalassemic cells is likely related to impaired cell maturation. KCC activity appears to contribute to erythroid cell growth during late erythropoiesis.
First-principles description of ferroelectric/electrode interfaces and properties of not very thin ferroelectric capacitors (2007)

We formulate an approach to the size effect problem in ferroelectric-electrode systems where <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">ab initio</i> calculations are combined with a phenomenological framework.

Salivary Vasodilators of Aedes triseriatus and Anopheles gambiae (Diptera: Culicidae) (1994)

Salivary vasodilators of Aedes aegypti (L.) and Anopheles albimanus (Wiedemann) were characterized previously as a tachykinin peptide and a catechol oxidase/peroxidase activity, respectively. To verify whether these two different vasodilators also were found in other distantly related members of each mosquito genus, we characterized the vasodilators from A. triseriatus and A. gambiae. A. triseriatus salivary gland homogenates produced a reversible, endothelium dependent vasorelaxation of rabbit aortic rings constricted with norepinephrine, and contracted an isolated guinea pig ileum preparation. Additionally, the homogenate had no activity on both smooth muscle preparations when both tissues were desensitized previously by a large dose of substance P. Taken together, these assays suggest the presence of a salivary tachykinin in A. triseriatus. A. gambiae salivary gland homogenates induced a slow vasodilation on both endothelium intact and endotheliumless preparations of aortic rings. A. gambiae homogenates also displayed catechol oxidase and peroxidase activity against o-dianisidine but not against serotonin, indicating the presence of an enzyme system slightly different from A. albimanus. We conclude that the presence of salivary tachykinins or catechol/oxidase is not unique to A. aegypti or A. albimanus.

A Comparative Investigation of Chemical Decontamination Methods for In-Situ Cleaning of Dental Implant Surfaces (2023)

Surface chemistry evaluation is crucial in assessing the efficacy of chemical decontamination products for titanium implants. This study aimed to investigate the effectiveness of chemical decontamination solutions in cleaning a contaminated dental implant surface and to evaluate the potential of combining Pluronic gel with hydrogen peroxide (NuBone<sup>®</sup>Clean) by evaluating pellicle disruption and re-formation on implant surfaces. In addition, ensuring safety with in vitro and human testing protocols. X-ray Photoelectron Spectroscopy (XPS) was utilised for surface analysis. All the tested gels had some effect on the surface cleanness except for PrefGel<sup>®</sup>. Among the tested chemical decontamination candidates, NuBone<sup>®</sup>Clean demonstrated effectiveness in providing a cleaner titanium surface. Furthermore, none of the tested chemical agents exhibited cytotoxic effects, and the safety assessment showed no adverse events. The results of this study highlight the significance of conducting comprehensive evaluations, encompassing safety and efficacy, before introducing new chemical agents for dental treatments. The findings suggest that NuBone<sup>®</sup>Clean shows potential as a chemical decontamination solution for implant surfaces. However, further investigation through randomised clinical trials is necessary. By adhering to rigorous testing protocols, the development of safe and efficient chemical decontamination strategies can be advanced, benefiting patients and promoting progress in implant dentistry.
Implementing automation in deep brain stimulation: has the time come? (2022)

In The Lancet Digital Health, Jan Roediger and colleagues1 present the results of a prospective, randomised, double-blind, crossover clinical trial assessing the therapeutic benefit of deep brain stimulation (DBS) settings derived from individual neuroimaging metrics. This evaluates a data-driven model of automated DBS parameter setting, maximising the predicted motor symptom control while accounting for potential stimulation-induced side-effects. Compared with current standard of care, the longer monopolar review based on existing clinical algorithms, the authors established non-inferiority of motor symptom control in a cohort of 35 patients with Parkinson's disease treated with DBS of the subthalamic nucleus.
Computational limits don't fully explain human cognitive limitations (2020)

The project of justifying all the limits and failings of human cognition as inevitable consequences of strategies that are actually "optimal" relative to the limits on computational resources available may have some value, but it is far from a complete explanation. It is inconsistent with both common observation and a large body of experimentation, and it is of limited use in explaining human cognition.
A compliant-mechanism approach to achieving specific quality of motion in a lumbar total disc replacement (2012)

Incorporation of segmental quality of motion into the foundational stages of the design process resulted in a total disc replacement design that provides torque-rotation and helical axis-of-motion characteristics to the adjacent segments and the operative-level facets that are similar to those observed in healthy spinal segments.
Hydrodynamic Pair Attractions between Driven Colloidal Particles (2011)

Colloidal spheres driven through water along a circular path by an optical ring trap display unexpected dynamical correlations. We use Stokesian dynamics simulations and a simple analytical model to demonstrate that the path's curvature breaks the symmetry of the two-body hydrodynamic interaction, resulting in particle pairing. The influence of this effective nonequilibrium attraction diminishes as either the temperature or the stiffness of the radial confinement increases. We find a well-defined set of dynamically paired states whose stability relies on hydrodynamic coupling in curving trajectories.
Xeroderma pigmentosum groups C and F: Additional assignments and a review of the subjects in Japan. (1985)

The differential bead-labelling method for heterodikaryon complementation enabled us to allocate xeroderma pigmentosum patients XP40KO and XP38KO to complementation groups C and F, respectively. Group C XP40KO cells exhibited 15% UDS and the 5 and 1.5-fold hypersenstivities to UV and 4-nitroquinoline-1-oxide (4NQO) killings, respectively, while group F XP38KO cells showed a higher residual level of 20-25% UDS and a less UV/4NQO hypersensitivity than did the previously assigned group F strains. We reviewed the thus far assigned Japanese groups C and F subjects for the repair and clinical characteristics. The present group C XP40KO was typical, while XP38KO was heterogrnous within group F with respect to repair.
Recently duplicated plant heterotrimeric Gα proteins with subtle biochemical differences influence specific outcomes of signal-response coupling (2017)

Heterotrimeric G-proteins, comprising Gα, Gβ, and Gγ subunits, regulate key signaling processes in eukaryotes. The Gα subunit determines the status of signaling by switching between inactive GDP-bound and active GTP-bound forms. Unlike animal systems, in which multiple Gα proteins with variable biochemical properties exist, plants have fewer, highly similar Gα subunits that have resulted from recent genome duplications. These proteins exhibit subtle differences in their GTP-binding, GDP/GTP-exchange, and GTP-hydrolysis activities, but the extent to which these differences contribute to affect plant signaling and development remains unknown. To evaluate this, we expressed native and engineered Gα proteins from soybean in an <i>Arabidopsis</i> Gα-null background and studied their effects on modulating a range of developmental and hormonal signaling phenotypes. Our results indicated that inherent biochemical differences in these highly similar Gα proteins are biologically relevant, and some proteins are more flexible than others in influencing the outcomes of specific signals. These observations suggest that alterations in the rate of the G-protein cycle itself may contribute to the specificity of response regulation in plants by affecting the duration of active signaling and/or by the formation of distinct protein-protein complexes. In species such as <i>Arabidopsis</i> having a single canonical Gα, this rate could be affected by regulatory proteins in the presence of specific signals, whereas in plants with multiple Gα proteins, an even more complex regulation may exist, which likely contributes to the specificity of signal-response coupling.

Ensuring trust in service consumption through security certification (2011)

The service-based paradigm is enabling new models of software provisioning based on cloud architectures. An increasing number of organizations are either providing their software as a service or acting as enablers by providing platforms on which service providers can offer their services. However the service implementations and the characteristics of the underlying cloud architectures are often opaque to the service consumers. The resulting deficit of trust on the security of such services is hampering the adoption of these new software paradigms by the industry.

Neuron Segmentation Based on CNN with Semi-Supervised Regularization (2016)

Neuron segmentation in two-photon microscopy images is a critical step to investigate neural network activities in vivo. However, it still remains as a challenging problem due to the image qualities, which largely results from the non-linear imaging mechanism and 3D imaging diffusion. To address these issues, we proposed a novel framework by incorporating the convolutional neural network (CNN) with a semi-supervised regularization term, which reduces the human efforts in labeling without sacrificing the performance. Specifically, we generate a putative label for each unlabeled sample regularized with a graph-smooth term, which are used as if they were true labels. A CNN model is therefore trained in a supervised fashion with labeled and unlabeled data simultaneously, which is used to detect neuron regions in 2D images. Afterwards, neuron segmentation in a 3D volume is conducted by associating the corresponding neuron regions in each image. Experiments on real-world datasets demonstrate that our approach outperforms neuron segmentation based on the graph-based semisupervised learning, the supervised CNN and variants of the semi-supervised CNN.
Microwave-Assisted Synthesis and Crystal Structure of 1-(4-Chlorophenyl)-4,5-diphenyl-2-(3,4,5-trimethoxy-phenyl)-1H-imidazole (2009)

The title compound, 1-(4-chlorophenyl)-4,5-diphenyl-2-(3,4,5-trimethoxy-phenyl)-1H-imidazole, was synthesized using a domestic microwave oven, and the structure of the product obtained was confirmed by X-ray diffraction (XRD) studies. The compound, C30H25ClN2O3, crystallizes in the triclinic crystal class in the space group with cell parameters a = 10.635(15) Å, b = 12.262(2) Å, c = 11.656(3) Å, α = 69.817(15)°, β = 64.630(6)°, γ = 73.503(16)°, and Z = 2. The structure has been solved by direct methods and refined to R 1 = 0.0764 for 3078 unique reflections with I > 2σ(I). The imidazole ring in the structure adopts a planar conformation. No classic hydrogen bonds were found in the structure.
