On the performance of advanced receivers in unsynchronized small cell LTE networks (2016)

Next generation long term evolution (LTE) systems evolve towards small cell networks to boost spectrum efficiency through extreme frequency reuse. To mitigate the impact of the resulting tremendous co-channel interference, advanced receivers supporting network assisted interference cancellation and suppression (NAICS) represent a promised technique to meet the ubiquitous cell edge free experience. However, as the interfering signals will reach the cell edge user equipment (UE) at varying delays, unsynchronized small cell networks might experience large timing offsets (TOs) and considerably limit the expected downlink (DL) performance. In this paper we focus on reliable channel estimation for diverse types of NAICS receivers operating in rich interfering small cell LTE networks. With analytical results we derive the impact of TOs on channel estimation, show that the promised performance of each of the NAICS receivers vanishes when neglecting the varying delays and against expectations perform worse than conventional linear interference suppression receivers. However, estimating and compensating the impact of the TOs, reliable channel estimation can be achieved and as a result the expected DL performance of each of the investigated NAICS receivers can be guaranteed in unsynchronized small cell LTE networks.

A Bismuth Metal–Organic Framework as a Contrast Agent for X-ray Computed Tomography (2019)

A new bismuth metal-organic framework (MOF), bismuth-NU-901 (Bi-NU-901), featuring the <i>scu</i> topology and a pore with a diameter of ∼11 Å, was solvothermally synthesized, and its use as an X-ray computed tomography (CT) contrast agent was tested. X-ray CT is a common diagnostic method used in the medical field. Inside the body, contrast media enhance the distinction between tissues and organs of similar density. Bi-NU-901 consists of eight connected Bi<sub>6</sub> nodes and tetratopic 1,3,5,8-(<i>p</i>-benzoate)pyrene linkers (TBAPy). Numerous material characterization studies including powder X-ray diffraction (PXRD), scanning transmission electron microscopy (STEM), and DFT pore size distribution support the <i>scu</i> structure. Additionally, given the framework's high density of nontoxic heavy atoms, Bi-NU-901 was evaluated as an X-ray computed tomography (CT) agent. Importantly, <i>in vitro</i> studies revealed this new bismuth MOF demonstrates ∼7 times better contrast intensity compared to a zirconium MOF featuring the same topology and ∼14 times better contrast than a commercially available CT contrast agent. These results suggest bismuth MOFs may be promising CT contrast agents.
Cell biology of cardiac mitochondrial phospholipids (2004)

Phospholipids are important structural and functional components of all biological membranes and define the compartmentation of organelles. Mitochondrial phospholipids comprise a significant proportion of the entire phospholipid content of most eukaroytic cells. In the heart, a tissue rich in mitochondria, the mitochondrial phospholipids provide for diverse roles in the regulation of various mitochondrial processes including apoptosis, electron transport, and mitochondrial lipid and protein import. It is well documented that alteration in the content and fatty acid composition of phospholipids within the heart is linked to alterations in myocardial electrical activity. In addition, reduction in the specific mitochondrial phospholipid cardiolipin is an underlying biochemical cause of Barth Syndrome, a rare and often fatal X-linked genetic disease that is associated with cardiomyopathy. Thus, maintenance of both the content and molecular composition of phospholipids synthesized within the mitochondria is essential for normal cardiac function. This review will focus on the function and regulation of the biosynthesis and resynthesis of mitochondrial phospholipids in the mammalian heart.
Shot Segmentation Technology by Using Machine Learning on Compressed Domain (2007)

To analyze the video structure and content,shot boundary features should be extracted exactly and efficiently.In this paper,a novel approach is proposed to detect shot boundaries by using Support Vector Machine(SVM) on the compressed domain features,which can be extracted without fully decompressing MPEG-1/2 video.Experimental results on TRECVID2005 shot boundary evaluation demonstrate that the proposed approach can obtain promising performance under good recall and precision.
Somatic Mutations and Clonal Hematopoiesis (2018)

Increasing evidence shows that conventional cardiovascular risk factors are incompletely predictive of cardiovascular disease, particularly in elderly individuals, suggesting that there may still be unidentified causal risk factors. Although the accumulation of somatic DNA mutations is a hallmark of aging, its relevance in cardiovascular disease or other age-related conditions has been, with the exception of cancer, largely unexplored. Here, we review recent clinical and preclinical studies that have identified acquired mutations in hematopoietic stem cells and subsequent clonal hematopoiesis as a new cardiovascular risk factor and a potential major driver of atherosclerosis. Understanding the mechanisms underlying the connection between somatic mutation-driven clonal hematopoiesis and cardiovascular disease will be highly relevant in the context of personalized medicine, as it may provide key information for the design of diagnostic, preventive, or therapeutic strategies tailored to the effects of specific somatic mutations.
Integrating SpyCatcher/SpyTag covalent fusion technology into phage display workflows for rapid antibody discovery (2019)

An early bottleneck in the rapid isolation of new antibody fragment binders using in vitro library approaches is the inertia encountered in acquiring and preparing soluble antigen fragments. In this report, we describe a simple, yet powerful strategy that exploits the properties of the SpyCatcher/SpyTag (SpyC/SpyT) covalent interaction to improve substantially the speed and efficiency in obtaining functional antibody clones of interest. We demonstrate that SpyC has broad utility as a protein-fusion tag partner in a eukaryotic expression/secretion context, retaining its functionality and permitting the direct, selective capture and immobilization of soluble antigen fusions using solid phase media coated with a synthetic modified SpyT peptide reagent. In addition, we show that the expressed SpyC-antigen format is highly compatible with downstream antibody phage display selection and screening procedures, requiring minimal post-expression handling with no sample modifications. To illustrate the potential of the approach, we have isolated several fully human germline scFvs that selectively recognize therapeutically relevant native cell surface tumor antigens in various in vitro cell-based assay contexts.
Implicit arbitrary shape visual objects via MPEG-4 scene description (2003)

First, a brief overview of the MPEG-4 standard is presented to highlight the fact that in order to achieve object based functionality, it requires arbitrary shaped visual objects. Next, a number of applications and their requirements are reviewed to determine the need for more than one class of solutions for visual shape representation. Then, a brief review of the solution for shape representation in MPEG-4 version 1 is presented, and, a solution that we have proposed for MPEG-4 version 2 is outlined. Details of our implicit shape coding which uses chromakey in MPEG4 systems scene description (BIFS) are then presented. Implementation of our shape representation in a real-time MPEC-4 player is then discussed. Finally we address the context in which our shape representation can address unique functionalities.
Nickel-Catalyzed Allylic Substitution of Simple Alkenes (2010)

Nickel-catalyzed intermolecular allylic substitution of simple alkenes (ethylene and alpha olefins) is described. This method is the first catalytic intermolecular process for direct allylation of nonconjugated, nonstrained simple alkenes. Catalyst loadings as low as 2.5 mol % Ni afford the desired product in high yield in both gram-scale and smaller scale coupling reactions.
Optical tweezers assembly line for the micro-assembly of functional zeolite nanocontainer structures (2013)

Summary form only given. Zeolite L is a microporous crystalline material featuring high number of strictly aligned one-dimensional nano-channels across the whole crystal axis. These porous silicate are highly interesting as building blocks because, by entrapping different guest molecules within their nano-pores, they can bridge the gap between the molecular and the microscopic world [1]. In particular, if loaded with organic dyes, the confinement exerted by the pore dimensions can enhance some of the emissive properties of the molecular guest. In order to achieve specific photonic functionalities, these building blocks can be arranged and assembled in specific configurations.In our contribution, we present an approach complementary to the established assembly schemes by utilizing holographic optical tweezers [2] in a microfluidic environment. We demonstrate an optical tweezers assembly line (OTAL) which enables the construction of sophisticated microstructures with full control over each individual constituent [3]. The developed OTAL consists of a microfluidic Y-channel that define two laminar fluid flows. One of the flows ensures supply of the building blocks in non-sticking conditions so that they can easily be selected and optically trapped while the other flow enables the zeolite crystals to attach to each other and to the substrate by utilizing van-der-Waal interactions. We discuss exciting applications of the presented zeolite L structures, e.g. as microscopic polarization sensor, and comment on the high potential of the OTAL for further parallelization of the constructions process by automation of the optical trapping process or utilization of more than the demonstrated separated flow lines. Figure 1 shows an example of an optically assembled functional structure. Three zeolite L crystals loaded with a green/yellow fluorescent DXP dye are arranged and hold together with HOT. The geometrical constraints imposed by the nano-channels of the host crystal result in a polarization-dependent fluorescence response of the aligned dye molecules. By means of linearly polarized fluorescence excitation, thus, the illumination pattern of the arranged building blocks can be selectively switched between different spatial states.
Replication-Competent ΔNS1 Influenza A Viruses Expressing Reporter Genes (2021)

The influenza A virus (IAV) is able to infect multiple mammalian and avian species, and in humans IAV is responsible for annual seasonal epidemics and occasional pandemics of respiratory disease with significant health and economic impacts. Studying IAV involves laborious secondary methodologies to identify infected cells. Therefore, to circumvent this requirement, in recent years, multiple replication-competent infectious IAV expressing traceable reporter genes have been developed. These IAVs have been very useful for in vitro and/or in vivo studies of viral replication, identification of neutralizing antibodies or antivirals, and in studies to evaluate vaccine efficacy, among others. In this report, we describe, for the first time, the generation and characterization of two replication-competent influenza A/Puerto Rico/8/1934 H1N1 (PR8) viruses where the viral non-structural protein 1 (NS1) was substituted by the monomeric (m)Cherry fluorescent or the NanoLuc luciferase (Nluc) proteins. The ΔNS1 mCherry was able to replicate in cultured cells and in Signal Transducer and Activator of Transcription 1 (STAT1) deficient mice, although at a lower extent than a wild-type (WT) PR8 virus expressing the same mCherry fluorescent protein (WT mCherry). Notably, expression of either reporter gene (mCherry or Nluc) was detected in infected cells by fluorescent microscopy or luciferase plate readers, respectively. ΔNS1 IAV expressing reporter genes provide a novel approach to better understand the biology and pathogenesis of IAV, and represent an excellent tool to develop new therapeutic approaches against IAV infections.

Vector quantization techniques for multiple-antenna channel information feedback (2005)

This paper presents vector quantization (VQ) techniques in the context of multiple-antenna systems with finite-rate feedback. For MISO systems, we introduce a new design criterion and develop the corresponding iterative design algorithm for quantization of the beamforming vector. For complexity-limited systems, tree-structured VQ is also examined and compared with the full-search VQ method. The method is extended to MIMO channels by employing a parameterization method that exploits the orthonormality in the spatial information matrix and using the MISO approach in a sequential manner. The parameterization method can also be used to develop an effective low-complexity scheme to deal with quantization of time-varying channels. Also briefly discussed is a matrix quantization method for feeding back the beamforming matrix in MIMO spatial multiplexing systems.
Joint PP and PS stratigraphic inversion for prestack time migrated multicomponent data (2004)

The goal of this paper is to improve the determination of a target zone located in a slowly laterally varying background, by jointly inverting PP and PS waves available in prestack time migrated multicomponent data, while taking into account a priori information (well log data, geological knowledge…) in the inversion process: an optimal elastic model is estimated together with an optimal correspondence between PP and PS events. The methodology and results are illustrated on a 2D realistic synthetic example.
Mullerian inhibiting substance requires its N-terminal domain for maintenance of biological activity, a novel finding within the transforming growth factor-beta superfamily. (1993)

Mullerian inhibiting substance (MIS)/anti-Mullerian hormone is a differentiation factor that causes regression of the Mullerian duct in the developing male fetus and an apparent sex reversal of the fetal ovary when inappropriately exposed to it. The purified product is a 140-kilodalton glycoprotein composed of two identical subunits. We show that a C-terminal fragment of MIS, which shares homology with transforming growth factor-beta, causes regression of the Mullerian duct and inhibits the biosynthesis of aromatase in the fetal ovary. However, both activities are enhanced dramatically by addition of the N-terminal portion of MIS. Under conditions where potentiation occurs, the N- and C-terminal domains of MIS reassociate. These results indicate that the N-terminus of MIS, unlike that of the other members of the transforming growth factor-beta family, plays a role in maintaining the biological activity of the C-terminus.
Growth and Characterization of Nitrogen-Doped MgSe/ZnSeTe Superlattice Quasi-Quaternary on InP Substrates and Fabrication of Light Emitting Diodes (1999)

Superlattice quasi-quaternaries (SL-QQs), consisting of MgSe/ZnSeTe short-period superlattices, were grown on InP substrates by molecular beam epitaxy with nitrogen p-doping. By changing the Mg composition (i.e., the layer thickness ratio of MgSe in the superlattice) from 0 to 0.76, the photoluminescence peak energy at 15 K increased from 2.11 to 2.68 eV. The N-doping of MgSe/ZnSeTe SL-QQs was performed by two processes, that is by the modulation-doping into ZnSeTe and by the all-doping. For the modulation-doping, a hole concentration of over 1×10 18 cm -3 was obtained for Mg composition of less than 0.14, with decreased monotonically with increasing Mg composition. The hole concentration increased by changing the doping process from the modulation-doping to the all-doping. For example, the hole concentration increased from 1×10 15 to 3×10 17 cm -3 for Mg composition of 0.4. ZnCdSe/MgZnCdSe(Te) light emitting diodes (LEDs) were fabricated using MgSe/ZnSeTe SL-QQs as p-cladding layers having yellow emissions around 577 nm at 77 K.
Si–C attachment points during sol–gel synthesis of organosilicas from 2,8-bis-silylated Tröger's base as building block precursor (2011)

The porous organosilica framework containing Tr oger's base (TB) prepared by mild sol-gel synthesis from 2,8-bis-silylated TB precursor contains a mixture of two point attached TB and one point attached TB units, resulting from unexpected partial Si-C bond cleavage as demonstrated by 29 Si MAS NMR spectroscopy and by selective chemo-desorption of the anchored organic part of the hybrid material.
Colloidal Gelation in Liquid Metals Enables Functional Nanocomposites of 2D Metal Carbides (MXenes) and Lightweight Metals (2023)

Nanomaterials dispersed in different media, such as liquids or polymers, generate a variety of functional composites with synergistic properties. This chapter discusses liquid metals as the nanomaterials’ dispersion media. 2D transitionmetal carbides and nitrides (MXenes) can be efficiently dispersed in liquid Ga and lightweight alloys of Al, Mg, and Li. The chapter shows that the Lifshitz theory predicts strong van der Waals attraction between nanoscale objects interacting through liquid metals. MXenes largely retain their phase and 2D morphology after processing in liquid Mg-Li alloy at 700 °C. MXenes are a large class of 2D metal carbides and nitrides, which have metal-terminated surfaces with tunable surface chemistry. One of the challenges for dispersing nanostructures directly into a liquid metal is poor wetting of ceramic surfaces by liquid metals.
Learning the "Epitome" of an Image (2002)

Estimating and visualizing high-order statistics of multivariate data is important for analysis, synthesis and visualization in science and engineering. Often, data consists of measurements on an underlying domain, such as space or time. Examples include images, audio signals and text, where the domains are 2-D space, 1-D time and 1-D symbol index. We introduce a model called the “epitome ” that can simultaneously represent multi-scale high-order statistics as a set of parameters on the same domain as the input data. A cost function measures how well multi-scale patches drawn from the input data match the epitome and this cost function can be optimized efficiently using the EM algorithm. Our technique reduces a large number of high-order statistics to an intuitive, compact representation that is suitable for a variety of data processing applications. We demonstrate our method using problems of object detection, texture segmentation and image retrieval. One approach to the problems of fully or semi-automated visualization, analysis and synthesis of data is to learn a compact model that accurately accounts for interesting properties of the data and can be used as a summary of the data [1, 2]. The hope is that the compact
