High-Impedance Surfaces Based on Self-Resonant Grids. Analytical Modelling and Numerical Simulations (2003)

A new variant of artificial high-impedance surfaces is suggested and studied. This is a thin composite layer consisting of a dielectric layer with a planar self-resonant grid from metal strips on its surface. Every grid element is connected to the ground plane with a metal pin. We use an analytical model which has been recently developed for a similar structure. The advantages of the new structure (decreasing the resonant frequency for fixed period and thickness, further angular stabilization of surface impedance for the TE-incidence of waves) are studied and explained. The analytical model is compared with numerical simulations. It predicts quite well the resonant frequencies of the artificial surface for different angles of incidence however is not enough accurate for calculating the values of the surface impedance.
Correlation between histidine operon expression and guanosine 5'-diphosphate-3'-diphosphate levels during amino acid downshift in stringent and relaxed strains of Salmonella typhimurium (1989)

We have analyzed the correlation of attenuator-independent expression of the Salmonella typhimurium histidine operon in vivo with levels of the "alarmone" guanosine 5'-diphosphate 3'-diphosphate. Amino acid downshift caused by serine hydroxamate addition increased his expression in a relA+ strain and decreased his expression in a relA mutant, whereas levels of guanosine 5'-diphosphate-3'-diphosphate varied in parallel with the changes in his expression in the two strains. In several experiments, overall variations in his expression ranged from 20- to 60-fold after downshift. The mild downshift allowed growth of the cultures to continue at near-preshift rates. Serine hydroxamate addition was also used to analyze the effect of amino acid downshift on induced expression of wild-type and mutant lac promoters. There was a 12-fold difference in lac expression when a relA+-relA1 pair was subjected to mild starvation but only a 3-fold difference when the strains carried the lacZpL8UV5 promoter mutation. These results suggest that guanosine 5'-diphosphate-3'-diphosphate stimulates gene expression in vivo at the level of transcription initiation.
Analysis and Minimization of Microloops in Link-state Routing Protocols (2005)

Link-state routing protocols (e.g. OSPF or IS-IS) are known to
converge to a loop-free state within a finite period of time after a
change in the topology. It is normal, however, to observe short-term
loops during the period of topology update propagation, route
recalculation, and forwarding table update, due to the asynchronous
nature of link-state protocol operation. This document provides an
analysis of formation of such microloops and suggests simple
mechanisms to minimize them.
Angelman syndrome: evolution of the phenotype in adolescents and adults (2001)

Individuals with Angelman syndrome (AS) have severe learning disability,* ataxia, seizures, dysmorphic facies, a happy, sociable disposition, and inability to speak. Most of the literature concerning the clinical features of AS has concentrated on younger children. This study aimed to look at the natural history of AS by documenting the clinical features in a group of 28 adolescents and adults with AS (12 males, 16 females; age range 16 to 40 years). Specific aspects studied included physical characteristics, general health, mobility, seizure disorder, behaviour and communication, and self-help skills. Problems seen in this older group of individuals differed significantly from those typically observed in younger children. The incidence of scoliosis and joint contractures increased with age. Facial features were more striking in adults. Hyperactivity and concentration improved and the sociable disposition persisted. There were subtle clinical differences between the groups of individuals with different underlying genetic abnormalities. Information obtained from this study is relevant to diagnosis and management of older individuals with AS.
Polarimetric Azimuthal Spectral Histogram Exposes Types of Mixed Scatterers and the Cause for Unexpected Polarimetric Averages (2007)

Echoes detected by polarimetric weather radar in clear air contain signals from air and biological scatterers. Discriminating the various scatterer types from a composite echo is challenging due to variability in scatterres' quantity, azimuthal dependences of their polarimetric properties, and uneven mixing in resolution volumes. We use polarimetric spectral densities to estimate the volume content by constructing two dimensional (2D) histograms. The dimensions used to form image are Doppler velocity and polarimetric variable. The assimilation of these histograms in azimuth results in a 3D-azimuthal-spectral-histogram (3DASH). This representation allows us to use transparency for small occurrences to visualize the 3D-signatures of dominant content. The scatterer types have distinguishable signatures in 3DASH due to their diverse physical shapes, scattering properties, different headings, and speeds. 3DASH can help to understand what constitutes the polarimetric averages of the resolution volume. 3DASH can help provide resources for establishing intrinsic polarimetric values/functions for different types of biological scatterers, which are necessary for scatterer classification algorithms.
Effects of ion beams on the early stages of MgO growth (2002)

Molecular dynamics simulations are performed to examine the effects of ion beams in selecting MgO island orientations during ion beam assisted deposition. Sputter yields are determined as a function of ion beam orientation for MgO islands of different sizes. While channeling does occur in small islands, the difference in sputter yields between channeling and nonchanneling orientations is much smaller in small islands than in larger islands or a continuous film. The ion beam is capable of disrupting the entire island structure at small island sizes, while channeling dependent sputtering occurs at larger island size. Since less sputtering occurs for channeling orientations, the ion beam produces an orientation-dependent island growth rate. This leads to island orientation-dependent nucleation rates. A new analytical model parameterized using the molecular dynamics sputter yield data is developed which predicts how growth conditions affect these island-orientation nucleation rates. Based upon these simulations and model results, we suggest a strategy to efficiently grow thin, highly textured MgO films.
Nonfouling Surface Coatings Based on Poly(2-methyl-2-oxazoline) (2008)

Surface fouling, i.e. the non-specific surface adhesion of proteins, bacteria and higher organisms, poses a severe problem in many areas ranging from modern diagnostic and therapeutic medical devices to food processing and food wrapping technology to corrosion prevention and marine technology. One approach to address these problems is to coat surfaces with nonfouling polymers. The properties of a new class of nonfouling polymer coatings made from poly(2-methyl-2-oxazoline) (PMOXA) were investigated here in comparison with the most frequently used polymer in this context, poly(ethylene glycol) (PEG). Both polymers were side-chain grafted onto a polycationic poly-L-lysine (PLL) backbone. The PMOXA graft copolymers spontaneously self-assembled to form monolayers on negatively charged surfaces. PMOXA surface coatings were as efficient as PEG-based coatings in suppressing protein and bacterial adsorption. The minimal number of side chain monomer units per surface area that are needed to obtain fully resistant surfaces was lower though for PMOXA than for PEG graft copolymers as a result of the higher molecular weight of the PMOXA monomer unit.
Modeling electromagnetic wave propagation in the troposphere using the parabolic equation (1988)

A computational method is described for predicting electromagnetic wave propagation in the troposphere using the parabolic approximation of the Helmholtz wave equation. The model represents propagation over a spherical, finitely conducting Earth and allows specification of frequency, polarization, antenna pattern, antenna altitude, and elevation angle. The method enables calculations to be performed using either ideal or measured refractivity profiles that vary in both altitude and range. A brief discussion of the theoretical formulation and computational implementation of the propagation model is presented, followed by examples that demonstrate various features. Example calculations include 3-GHz propagation over a calm sea in the presence of both range-dependent and range-independent surface-based ducts as well as in standard atmosphere conditions. Comparisons with two other propagation models are also discussed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
KSM++: Using I/O-based hints to make memory-deduplication scanners more efficient (2012)

Memory scanning deduplication techniques, as implemented in Linux' Kernel Samepage Merging (KSM), work very well for deduplicating fairly static, anonymous pages with equal content across different virtual machines. However, scanners need very aggressive scan rates when it comes to identifying sharing opportunities with a short life span of up to about 5 min. Otherwise, the scan process is not fast enough to catch those short-lived pages. Our approach generates I/O-based hints in the host to make the memory scanning process more efficient, thus enabling it to find and exploit short-lived sharing opportunities without raising the scan rate. Experiences with similar techniques for paravirtualized guests have shown that pages in a guest’s unified buffer cache are good sharing candidates. We already identify such pages in the host when carrying out I/O-operations on behalf of the guest. The target/source pages in the guest can safely be assumed to be part of the guest’s unified buffer cache. That way, we can determine good sharing hints for the memory scanner. A modification of the guest is not required. We have implemented our approach in Linux. By modifying the KSM scanning mechanism to process these hints preferentially, we move the associated sharing opportunities earlier into the merging stage. Thereby, we deduplicate more pages than the baseline system. In our evaluation, we identify sharing opportunities faster and with less overhead than the traditional linear scanning policy. KSM needs to follow about seven times as many pages as we do, to find a sharing opportunity.

p90 ribosomal S6 kinase 3 contributes to cardiac insufficiency in α-tropomyosin Glu180Gly transgenic mice (2013)

Myocardial interstitial fibrosis is an important contributor to the development of heart failure. Type 3 p90 ribosomal S6 kinase (RSK3) was recently shown to be required for concentric myocyte hypertrophy under in vivo pathological conditions. However, the role of RSK family members in myocardial fibrosis remains uninvestigated. Transgenic expression of α-tropomyosin containing a Glu180Gly mutation (TM180) in mice of a mixed C57BL/6:FVB/N background induces a cardiomyopathy characterized by a small left ventricle, interstitial fibrosis, and diminished systolic and diastolic function. Using this mouse model, we now show that RSK3 is required for the induction of interstitial fibrosis in vivo. TM180 transgenic mice were crossed to RSK3 constitutive knockout (RSK3(-/-)) mice. Although RSK3 knockout did not affect myocyte growth, the decreased cardiac function and mild pulmonary edema associated with the TM180 transgene were attenuated by RSK3 knockout. The improved cardiac function was consistent with reduced interstitial fibrosis in the TM180;RSK3(-/-) mice as shown by histology and gene expression analysis, including the decreased expression of collagens. The specific inhibition of RSK3 should be considered as a potential novel therapeutic strategy for improving cardiac function and the prevention of sudden cardiac death in diseases in which interstitial fibrosis contributes to the development of heart failure.
Notch2 is involved in the overexpression of CD23 in B-cell chronic lymphocytic leukemia (2002)

Members of the Notch family encode transmembrane receptors that modulate differentiation, proliferation, and apoptotic programs of many precursor cells, including hematopoietic progenitors. Stimulation of Notch causes cleavage followed by translocation of the intracellular domain (NotchIC) to the nucleus, where it activates transcription of CBF1 responsive genes. The aim of this study was to elucidate the mechanisms leading to the overexpression of CD23, a striking feature of B-cell chronic lymphocytic leukemia (B-CLL) cells. By electrophoretic mobility shift assays, we identified a transcription factor complex (C1) that binds sequence specific to one known and 4 newly identified putative CBF1 recognition sites in the CD23a core promoter region. With the use of Epstein-Barr virus (EBV)-infected B cells as a model for CBF1 mediated CD23a expression, C1 was found to be EBV inducible. Supershift assays revealed that the nuclear form of Notch2 is a component of C1 in B-CLL cells, supporting a model in which NotchIC activates transcription by binding to CBF1 tethered to DNA. Transient transfection of REH pre-B cells with an activated form of Notch2 induced endogenous CD23a, confirming that CD23a is a target gene of Notch2 signaling. Finally, reverse transcription-polymerase chain reaction and kinetic analysis demonstrated that the Notch2 oncogene is not only overexpressed in B-CLL cells but might also be related to the failure of apoptosis characteristic for this disease. In conclusion, these data suggest that deregulation of Notch2 signaling is involved in the aberrant expression of CD23 in B-CLL.

Calibration of the Wild P32 Camera Using the Camera‐On‐Theodolite Method (1998)

The calibration of phototheodolites such as the Wild P32/T2 combination sometimes involves determining not only the camera interior orientation parameters but also the camera‐to‐theodolite parameters. The latter become particularly important when the theodolite set orientation parameters are to be used as observations, especially as known quantities for data reduction in subsequent photogrammetric applications. This paper presents experiments to determine these parameters for a Wild P32 camera using a new camera‐on‐theodolite method, with details of results achieved.
Low complexity bit-parallel multipliers for a class of finite fields (1998)

New implementations of bit-parallel multipliers for a class of finite fields are proposed. The class of finite fields is constructed with irreducible AOPs (all one polynomials) and ESPs (equally spaced polynomials). The size and time complexities of our proposed multipliers are lower than or equal to those of the previously proposed multipliers of the same class.
H3K27M induces defective chromatin spread of PRC2-mediated repressive H3K27me2/me3 and is essential for glioma tumorigenesis (2019)

Lys-27-Met mutations in histone 3 genes (H3K27M) characterize a subgroup of deadly gliomas and decrease genome-wide H3K27 trimethylation. Here we use primary H3K27M tumor lines and isogenic CRISPR-edited controls to assess H3K27M effects in vitro and in vivo. We find that whereas H3K27me3 and H3K27me2 are normally deposited by PRC2 across broad regions, their deposition is severely reduced in H3.3K27M cells. H3K27me3 is unable to spread from large unmethylated CpG islands, while H3K27me2 can be deposited outside these PRC2 high-affinity sites but to levels corresponding to H3K27me3 deposition in wild-type cells. Our findings indicate that PRC2 recruitment and propagation on chromatin are seemingly unaffected by K27M, which mostly impairs spread of the repressive marks it catalyzes, especially H3K27me3. Genome-wide loss of H3K27me3 and me2 deposition has limited transcriptomic consequences, preferentially affecting lowly-expressed genes regulating neurogenesis. Removal of H3K27M restores H3K27me2/me3 spread, impairs cell proliferation, and completely abolishes their capacity to form tumors in mice.

Visual industrial inspection using aerial robots (2014)

The use of unmanned aerial vehicles (UAV) offers a unique possibility to capture visual information in areas which are hard to reach or dangerous for humans. For UAVs to become a standard tool in visual inspection, it is of utmost importance that the aerial robot can be operated efficiently by a non-expert UAV pilot and that the navigation system is robust enough to remain operational in rough, industrial conditions. To this end, we present a UAV navigation system setup that uses visual-inertial sensor cues to estimate the UAV pose as well as to create a dense 3D map of the environment in real-time onboard the UAV, completely independent of GPS. The proposed navigation system enables the operator to directly interface the UAV using high-level commands such as waypoints or velocity commands while the navigation system ensures a stable and collision-free flight.

Paramagnetic Cluster Ions [B<sub>6</sub>Hal<i><sub>n</sub></i>Hal‘<sub>6</sub><sub>-</sub><i><sub>n</sub></i>]<sup>•</sup><sup>-</sup> (Hal, Hal‘ = Cl, Br, I). EPR Evidence for Radical Stabilization through Electronic Effects of the Halogen Substituents (1998)

Monoanionic hexaborate cluster radicals [B(6)Hal(n)()Hal'(6)(-)(n)()](*)(-) with mixed halogen substitution were prepared from oxidizable dianionic precursors and were characterized by vibrational and UV-vis spectroscopy. EPR studies of these and the structurally established homoleptic species [B(6)Hal(6)](*)(-) (Hal = Cl, Br, I) reveal strongly increasing g anisotropy and relaxation rate on replacing Cl by Br and especially I substituents; the very stable B(6)I(6)(*)(-) ion (g(1) = 2.04, g(2) = 1.66, g(3) = 1.15) thus exhibits an EPR spectrum only at 4 K. The extent of these effects is attributed to the Jahn-Teller situation in [B(6)X(6)](*)(-) with only partial occupancy of a degenerate MO. Both the absence of B-H bonds and the evidently strong participation of the halogen substituents in the singly occupied MO contribute to the extraordinary stability of these cluster radicals.
Multidrug efflux systems in Gram-negative bacteria (2004)

Multidrug efflux mechanisms in bacteria contribute significantly to intrinsic and acquired resistance to antimicrobial agents. Genome analysis have confirmed the broad distribution of these systems in Gram-negative as well as in Gram-positive bacteria. Among resistance mechanisms, the multidrug efflux system or pump deserves special attention, since a cell that has acquired it can simultaneously diminish or even suppress the susceptibility to a wide range of antimicrobials. The efflux system is mediated by transport proteins which confer resistance to toxic compounds. In Gram-negative bacteria, a tripartite efflux system is necessary to expel the drug to the outer medium: a protein localized in the cytoplasmic membrane; another in the periplasmatic space (membrane fusion protein - MFP); and a third in the outer membrane (outer membrane factor - OMF). The drug transport is active, and depends either on the energy provided by ATP hydrolysis or is directly driven by the proton motive force. The transport proteins are grouped in families, according to the homology of the amino acid sequences and to similarity of mechanisms. Among Gram-negative bacteria, Escherichia coli and Pseudomonas aeruginosa have most of the hitherto identified and studied multidrug efflux systems.
