Geometrical Cluster-Based Scatterer Detection Method with the Movement of Mobile Terminal (2015)

When a mobile station moves along a trajectory, it will see different parts of the same scatterers or scatterer groups during its movement. In this paper, we present a new method to identify such physical clusters of scatterers, and the corresponding groups of multipath components (MPCs) interacting with those clusters, from measurements of channel impulse responses. The method is based on identifying MPCs that have similar long-term properties - in the sense that they ``effectively interact with'' the same physical clusters, The method consists of four steps: (1) estimate the delays, the DOAs and the amplitudes of the MPCs in each time snapshot; (2) track the MPCs in the time-delay domain; (3) localize all the scattering points in a 2-D Cartesian coordinate system and cluster them on a map with a traditional Kmeans clustering algorithm; (4) merge the scattering points of different MPCs into physical clusters. The method is evaluated using both synthetic data and real measurement data from a suburban area. In the latter case, the locations and the sizes of the interacting objects identified from the measurements show excellent agreement with the location of physical objects in the environment such as pillars and buildings.
Precision Polyelectrolytes with Phenylsulfonic Acid Branches at Every Five Carbons (2018)

A precision polyethylene containing phenyl branches at every fifth carbon (p5Ph) is nearly quantitatively functionalized (≈95%) with sulfonic acid groups on the para-position of each phenyl branch (p5PhS-H). Unlike polystyrene sulfonate (PSS), p5PhS-H has a glass transition temperature (T<sub>g</sub> = 109 °C) well below its thermal decomposition temperature (T<sub>d</sub> ≈ 200 °C), making this new material capable of thermal processing into molds and films at temperatures between these thermal limits. Neutralization of the sulfonic acid groups with varying counter cations (Li<sup>+</sup> , Na<sup>+</sup> , Cs<sup>+</sup> ) produces a new class of precision polyelectrolytes. Neutralization and increasing size of the counter cation improves the thermal decomposition temperature (T<sub>d</sub> ) to over 400 °C for the Cs<sup>+</sup> form. Neutralization causes T<sub>g</sub> to increase above T<sub>d</sub> for the Li<sup>+</sup> and Na<sup>+</sup> form. The Cs<sup>+</sup> form is found to have an accessible T<sub>g</sub> = 294 °C. Further investigations of water absorption and the polyelectrolyte effect of these systems are discussed.
Effect of beam energy and surface temperature on the dissociative adsorption of H2 on Si(001) (1999)

Dissociative adsorption of H2 from a high-flux supersonic molecular beam on flat and vicinal Si(001) surfaces was investigated by means of optical second harmonic generation (SHG). The initial sticking coefficients for terrace adsorption varied between 10−8 and 10−4. They revealed a strongly activated dissociation process, both with respect to the kinetic energy of the incident molecules (70 meV⩽Ekin⩽380 meV) and the surface temperature (440 K⩽Ts⩽670 K). The results indicate that dynamical distortions of Si surface atoms can lower the effective adsorption barriers from 0.8±0.2 eV to almost negligible values. Previously proposed defect-mediated processes can be ruled out as a major adsorption channel.

Open source HEVC analyzer for rapid prototyping (HARP) (2014)

The design of new HEVC extensions comes with the need for careful analysis of internal HEVC codec decisions. Several bitstream analyzers have evolved for this purpose and provide a visualization of encoder decisions as seen from a decoder viewpoint. None of the existing solutions is able to provide actual insight into the encoder and its RDO decision process. With one exception, all solutions are closed source and make adaption of their code to specific implementation needs impossible. Overall, development with the HM code base remains a time-consuming task. Here, we present the HEVC Analyzer for Rapid Prototyping (HARP), which directly addresses the above issues and is freely available under www.lms.lnt.de/HARP.
Correlation between Serum and Plasma Antibody Titers to Mycobacterial Antigens (2010)

The ability to utilize serum or plasma samples interchangeably is useful for tuberculosis (TB) serology. We demonstrate a strong correlation between antibody titers to several mycobacterial antigens in serum versus plasma from HIV-infected and non-HIV-infected TB and non-TB patients (r = 0.99 to 0.89; P < 0.0001). Plasma and serum can be used interchangeably in the same antibody detection assays.
Negative-acting factor and superantigen are separable activities of the mouse mammary tumor virus long terminal repeat. (1995)

The open reading frame contained within the long terminal repeat (LTR) of mouse mammary tumor virus encodes Naf, a negative regulator of transcription, as well as a superantigen activity, Sag, which causes the deletion of specific classes of T cells. In the present study, the effect of Naf expression on different promoters and the coding requirements for Naf and Sag have been investigated. Sag activity was found to require only sequences in the LTR, whereas sequences located within the gag gene were additionally required for functional Naf activity. Surprisingly, both the classic promoter and a recently described promoter located in the LTR can give rise to both functional Naf and Sag. Further analysis of Naf revealed that the downregulatory effect was mediated by sequences located in the LTR and that heterologous promoters were also affected by Naf.
The Hardware Foundation of 6G: The NEW-6G Approach (2022)

The design of future 6th Generation (6G) wireless connect-compute-control networks requires new approaches for the design of hardware, new materials and hybridization processes new technological solutions, to create a sustainable foundation for the effective operation of innovative services and use cases. In this context, the New-6G initiative focuses on solutions that capitalize on the latest advances in high-performance semiconductor technologies, integrated circuits, digital components, and wide bandwidth radio frequencies. Based on the applications and use cases, we propose two main loci that will have the largest impact: the challenges and opportunities of baseband processing on the one hand and material enablers and related device and circuit challenges on the other hand. For this second part, BiCMOS, FD-SOI, GaN and InP are highlighted as especially of interest. BiCMOS and FD-SOI have already demonstrated their possible application up to 200GHz. While BiCMOS could be potentially used at higher frequencies, III-V (GaN, InP) alternatives when integrated with CMOS could propose cost-effective solution to address higher-power and higher-efficiency sub-THz 6G applications.
PREDICTING NOISE-INDUCED HEARING LOSS (NIHL) IN TNB WORKERS USING GDAM ALGORITHM (2012)

Noise is a form of a pollutant that is terrorizing the occupational health experts for
many decades due to its adverse side-effects on the workers in the industry. Noise-
Induced Hearing Loss (NIHL) handicap is one out of many health hazards caused
due to excessive exposure to high frequency noise emitted from the machines. A
number of studies have been carried-out to find the significant factors involved in
causing NIHL in industrial workers using Artificial Neural Networks (ANN). Despite
providing useful information on hearing loss, these studies have neglected some
important factors.
The traditional Back-propagation Neural Network (BPNN) is a supervised
Artificial Neural Networks (ANN) algorithm. It is widely used in solving many real
time problems in world. But BPNN possesses a problem of slow convergence and
network stagnancy. Previously, several modifications were suggested to improve the
convergence rate of Gradient Descent Back-propagation algorithm such as careful
selection of initial weights and biases, learning rate, momentum, network topology,
activation function and ‘gain’ value in the activation function.
This research proposed an algorithm for improving the current working
performance of Back-propagation algorithm by adaptively changing the momentum
value and at the same time keeping the ‘gain’ parameter fixed for all nodes in the
neural network. The performance of the proposed method known as ‘Gradient
Descent Method with Adaptive Momentum (GDAM)’ is compared with ‘Gradient
Descent Method with Adaptive Gain (GDM-AG)’ (Nazri, 2007) and ‘Gradient
Descent with Simple Momentum (GDM)’ by performing simulations on
classification problems. The results show that GDAM is a better approach than
previous methods with an accuracy ratio of 1.0 for classification problems like Thyroid disease, Heart disease, Breast Cancer, Pima Indian Diabetes, Wine Quality,
Australian Credit-card approval problem and Mushroom problem.
The efficiency of the proposed GDAM is further verified by means of
simulations on Noise-Induced Hearing loss (NIHL) audiometric data obtained from
Tenaga Nasional Berhad (TNB). The proposed GDAM shows improved prediction
results on both ears and will be helpful in improving the declining health condition of
industrial workers in Malaysia. At present, only few studies have emerged to predict
NIHL using ANN but have failed to achieve high accuracy. The achievements made
by GDAM has paved way for indicating NIHL in workers before it becomes severe
and cripples him or her for life. GDAM is also helpful in educating the blue collared
employees to avoid noisy environments and remedies against exposure to excessive
noise can be taken in the future to prevent hearing damage.
Crosstalk of Histone Modifications in the Healthy Human Immune System (2022)

ABSTRACT Chromatin remodeling through post-translational modifications of histone tails (HPTM) is fundamental for regulation and maintenance of DNA-centered processes. Systems level understanding of coordination and interactions between HPTMs and their impact on the functional state of the immune cells remain unexplored due to the technical reasons. We leveraged large biologically heterogeneous data (&gt;27 million cells), comprising of primary human immune cells profiled for 33 HPTMs and 4 histone variants at the single-cell level using high-dimensional mass cytometry (EpiTOF), to discover and map relations between HPTMs at the systems level. Briefly, we elucidated a comprehensive epigenetic network of HPTM interactions, discovered a novel subset of hematopoietic progenitors with distinct epigenetic profile, and revealed hitherto undescribed associations between a decrease in global methylations, modulation of one-carbon metabolism, and immune cell life span. Ultimately our work lays a foundation for future studies aimed at understanding complexity of HPTM interactions in immune response in infectious or autoimmune diseases, cancers, and vaccination.
Total hip replacement with insertion of an acetabular component without cement and a femoral component with cement. Four to seven-year results. (1995)

One hundred and fifty-three so-called hybrid total hip replacements were performed in 142 patients from 1985 to 1987 at Rush-Presbyterian-St. Luke's Medical Center. A hemispherical porous-coated acetabular component was inserted without cement and was fixed with screws, and a femoral stem was inserted with the use of so-called third-generation cementing techniques. The average age of the patients at the time of the operation was sixty-seven years (range, thirty-nine to eighty-five years). The average preoperative Harris hip score was 46 points (range, 9 to 73 points). One hundred and eleven patients (120 hips) were available for clinical review; 100 of these patients (109 hips) had a complete set of radiographs available. The average Harris hip score was 86 points (range, 29 to 100 points) at the time of follow-up (average duration, sixty-two months; range, forty-eight to eighty-five months). There was progressive migration of one cup (1 per cent); another cup migrated one centimeter in the first two years after the operation, with no additional migration evident after that time. The remaining acetabular components were stable. Two femoral components (2 per cent) were determined to be definitely loose. The remaining femoral components were stable. This population of patients had a good result after so-called hybrid total hip replacement with insertion of a porous-coated acetabular component without cement and a femoral component with cement for the reconstruction of a painful hip.
Laser‐induced thermotherapy (LITT) of liver metastases: MR‐guided percutaneous insertion of an MRI‐compatible irrigated microcatheter system using a closed high‐field unit (2003)

The new microcatheter system allows for both catheter placement and monitoring of therapy using a single imaging modality. This shortens the procedure and enables more precise puncture and therapy of liver metastases. Due to the miniaturized design of the catheter and the real-time monitoring, the procedure is minimally invasive and very well tolerated by patients. This new technique seems to be a safe and feasible alternative in treating liver metastases.
Elucidating the Kinetics of Expression and Immune Cell Infiltration Resulting from Plasmid Gene Delivery Enhanced by Surface Dermal Electroporation (2013)

The skin is an attractive tissue for vaccination in a clinical setting due to the accessibility of the target, the ease of monitoring and most importantly the immune competent nature of the dermal tissue. While skin electroporation offers an exciting and novel future methodology for the delivery of DNA vaccines in the clinic, little is known about the actual mechanism of the approach and the elucidation of the resulting immune responses. To further understand the mechanism of this platform, the expression kinetics and localization of a reporter plasmid delivered via a surface dermal electroporation (SEP) device as well as the effect that this treatment would have on the resident immune cells in that tissue was investigated. Initially a time course (day 0 to day 21) of enhanced gene delivery with electroporation (EP) was performed to observe the localization of green fluorescent protein (GFP) expression and the kinetics of its appearance as well as clearance. Using gross imaging, GFP expression was not detected on the surface of the skin until 8 h post treatment. However, histological analysis by fluorescent microscopy revealed GFP positive cells as early as 1 h after plasmid delivery and electroporation. Peak GFP expression was observed at 24 h and the expression was maintained in skin for up to seven days. Using an antibody specific for a keratinocyte cell surface marker, reporter gene positive keratinocytes in the epidermis were identified. H&amp;E staining of treated skin sections demonstrated an influx of monocytes and granulocytes at the EP site starting at 4 h and persisting up to day 14 post treatment. Immunological staining revealed a significant migration of lymphocytic cells to the EP site, congregating around cells expressing the delivered antigen. In conclusion, this study provides insights into the expression kinetics following EP enhanced DNA delivery targeting the dermal space. These findings may have implications in the future to design efficient DNA vaccination strategies for the clinic.
Multiple-pseudogap phases in the hydrogen-doped LaFeAsO system (2017)

The low-energy electronic structure of $\mathrm{LaFeAs}{\mathrm{O}}_{1\ensuremath{-}x}{\mathrm{H}}_{x}$ $(0.0\ensuremath{\le}x\ensuremath{\le}0.60)$, a system which exhibits two superconducting domes and antiferromagnetic orders in its phase diagram, is investigated by utilizing laser photoemission spectroscopy. From the precise temperature-dependent measurement of the spectra near the Fermi level, we find a suppression of the density of states with cooling, namely a pseudogap formation, for all doping range. The pseudogap gets suppressed on doping through the first superconducting dome regime to the higher-$x$ region, whereas it tends to recover when further increasing $x$ toward the second antiferromagnetic ordered phase. The systematic doping dependence indicates the different origins of pseudogaps in the low- and high-$x$ regions, possibly related to the respective antiferromagnetic ground states residing at both ends of the phase diagram.

Evaluation of Baroclinic ADCIRC Using a Process-Oriented Test along a Slope (2012)

Process-oriented tests, such as those suggested by Haidvogel and Beckmann (1999), are often utilized in the validation of baroclinic processes in shallow water models. In a previous analysis, the so-called "lock-exchange" or "dam break" problem on a flat slope, wherein a vertical barrier that separates water of different densities is removed at time zero, was utilized in the validation of the baroclinic additions to the shallow water ADCIRC (ADvanced CIRCulation) model (Kolar et al., 2009). More specifically, a laboratory-scale model was utilized to capture high-resolution data sets of the lock-exchange problem. These data sets allowed for direct comparison throughout the domain of the experimental and numerical results. Results showed good agreement between model and laboratory results, sans the shear instabilities along the interface. Using these same techniques, we analyzed a density front along a slope, the "gravity adjustment" test case suggested by Haidvogel and Beckmann (1999). In this analysis, water of different densities is separated by a vertical barrier that is removed at time zero, allowing the more dense water to travel down the slope. Data is captured every 0.2 seconds using high-resolution digital photography, with salt concentration extracted by comparing pixel intensity of the dyed fluid against calibration standards. Herein, experimental results are compared to numerical results for the location of the front, along with the average root mean square errors of the salinity field.
Evaluation of bandwidth and power consumption in reconfigurable fronthaul network architecture (2016)

The introduction of the Common Public Radio Interface (CPRI) technology allows for a centralization in Base Bandwidth Unit (BBU) of some access functions with advantages in terms of power consumption saving when switching off algorithms are implemented. Unfortunately the advantages of the CPRI technology is to be paid with an increase in bandwidth to be carried between the BBU and the Radio Remote Unit (RRU) in which only the radio functions are implemented. Bandwidth saving can be achieved with the use of a reconfigurable network carrying the traffic generated by the RRUs towards the Cental Office (CO) where the BBUs are located. We introduce an analytical model to evaluate the bandwidth and power consumptions and observe how, due to statistical multiplexing effects, the savings increase when the number of RRUs managed by each of the Access Nodes of the reconfigurable network increases. For instance we show how in 5G traffic scenarios, this percentage saving can vary from 30% to 50% according to total traffic amount handled by a switching node of the reconfigurable network.
Molecular dynamics simulations of the chiral recognition mechanism for a polysaccharide chiral stationary phase in enantiomeric chromatographic separations (2019)

We use explicit-solvent fully atomistic molecular dynamics (MD) simulations, permitting all the interactions between the atoms constituting the polymeric chiral stationary phase (CSP), the solvent molecules and the drug molecule enantiomers, to better understand the chiral recognition mechanism that makes chromatographic separation possible. Using amylose tris(3,5-dimethylphenyl carbamate) (ADMPC) as prototype, three solvent systems, and ten racemates as solutes, we seek a molecular dynamics average quantity that could serve as a metric that predicts which of the two enantiomers will elute first and also correlates with the ratio of retention times for enantiomers. To better understand the molecular dynamic chiral recognition that provides the discrimination which results in the separation of enantiomers by high performance liquid chromatography, we examine the differences in hydrogen bonding lifetimes in various donor–acceptor pairs between the drugs and the ADMPC, and map out the differences in ring-ring interactions between the drugs and the ADMPC. Several MD average quantities related to hydrogen-bonding lifetimes correlate with the ratio of retention times for the enantiomers. One of these quantities provides a prediction of the correct elution order 90% of the time, and the ratios of these quantities for the enantiomers provide linear correlation (0.85 coefficient) with experimental separation factors.
Interpretation of High Resolution Lattice Image of Thick Crystal (1981)

A wealth of information on structural details in the images of thick crystals has been demonstrated. This paper is concerned with interpretation of the HREM images of thick crystals. To save the cost of the HREM image calculation, a computation method for the multislice formulation will be economical. Our previous studies of a crystal of niobium oxides showed that the HREM images appearing in thin regions recurred in thicker regions (Fig. 1). The simulation of this recurrence would be a measure to judge the validity of the calculation. The calculated amplitudes for some beams contributing to the image are shown in Fig. 2. The HREM images corresponding to the thicknesses indicated in Fig. 2 are simulated using our experimental parameters. The recurrence of the image is reproduced clearly in this calculation (Fig. 1). The result is encouraging for the analysis of thick crystals in terms of their structural details.
Association of congenital heart defects with season and population density (1976)

Infants born in New England with congenital heart defects were examined for association with time of year or population density. Moderate seasonal peaks in births were noted for complex ventricular septal defect, malposition defects, and transposition of the great arteries. Positive associations with population density were found for pulmonary atresia with ventricular septal defect, ventricular septal defect with secondary anomalies, and tricuspid atresia.
A Small‐Molecule Antagonist of the Hedgehog Signaling Pathway (2007)

Results from biochemical and cellular experiments suggest that JK184 functions by inhibiting class IV alcohol dehydrogenase. This molecule should serve as a useful tool for studying Hedgehog signaling.
