Self-Assembly of Flexible One-Dimensional Coordination Polymers on Metal Surfaces (2010)

We employed a de novo synthesized porphyrin module to construct one-dimensional (1D) Cu-coordinated polymers on Cu(111) and Ag(111) surfaces. The programmed geometry and functionality of the molecular module together with its conformational flexibility and substrate interaction yields sinuous metal-organic polymeric assemblies, based on an unusual two-fold Cu-pyridyl coordination motif. An analysis of scanning tunneling microscopy (STM) data reveals the occurrence of two enantiomers, resulting from the surface confinement that deconvolutes the module in 2D-chiral conformational isomers. The stereoisomers exhibit site-specific surface anchoring, from whence three discrete orientations are possible for each species. Their sequence and mutual arrangement determine direction and curvature of the metal-organic chains. The Cu-coordinated polymers are very similar on both Cu(111) and Ag(111), where their formation is induced by intrinsic and coevaporated adatoms, respectively, which indicates that the lateral bonding motif is predominantly independent of the substrate. In addition, molecular manipulation experiments show the collective motion of entire segments of the Cu-coordinated multi-porphyrin polymers.
[Publication activity at Aalborg Hospital]. (2010)

The study shows that the increased focus on research has led to increased publication activity without loss of quality, as the decrease in points per publication is associated with the increased mean number of collaborators. The results indicate that the method would benefit from a revision to facilitate clearer conclusions.
An Interactive Curtain for Media Usage in the Shower (2015)

Access to digital information became almost ubiquitous. There are only few situations left where digital media cannot be accessed. Showering is probably the only regular and common activity that does not allow to access and interact with digital media. Based on a large-scale survey, we identified potential applications that users want to use in the shower and designed a system that augments the user's showering experience to provide pervasive media access. We developed a projection-based system that augments shower curtains from the back side and recognizes user input using a thermal camera. Through a user study in a running shower, we collected feedback from potential users and evaluated different algorithms to recognize touch input on a shower curtain. Our results show that participants are enthusiastic about accessing and controlling media using an interactive shower curtain. Furthermore, we identified two algorithms that are robust enough to be used in challenging environments such as a shower.
Novel Hybrid 12-Pulse Line-Interphase-Transformer Boost-Type Rectifier with Controlled Output Voltage and Sinusoidal Utility Currents (2007)

A novel injection scheme to improve the input current harmonics of a hybrid 12-pulse line-interphase-transformer rectifier with controlled output voltage by a two-switch boost-type output stage is presented in this paper. A theoretical derivation of the modulation for achieving purely sinusoidal input currents is introduced. Finally, the proposed scheme is analyzed and verified by numerical simulations and experimental results.
Mode-selecting acoustic filter by using resonant tunneling of two-dimensional double phononic crystals (2005)

In this letter, we investigated the resonant tunneling of elastic waves through double phononic potential barriers formed by two slabs of two-dimensional phononic crystals consisting of pure solid components. It is found that the resonant tunneling longitudinal waves can be distinguished easily from the resonant tunneling transverse waves. Thus, such double-barrier structures can be served as a mode-selecting acoustic filter, used to pick out the single longitudinal wave component or transverse wave component at a certain frequency.
In vitro blood cell viability profiling of polymers used in molecular assembly (2017)

Biocompatible polymers have been extensively applied to molecular assembly techniques on a micro- and nanoscale to miniaturize functional devices for biomedical uses. However, cytotoxic assessments of developed devices are prone to partially focus on non-specific cells or cells associated with the specific applications. Thereby, since toxicity is dependent on the type of cells and protocols, we do not fully understand the relative toxicities of polymers. Additionally, we need to ensure the blood cell biocompatibility of developed devices prior to that of targeted cells because most of the devices contact the blood before reaching the targeted regions. Motivated by this issue, we focused on screening cytotoxicity of polymers widely used for the layer-by-layer assembly technique using human blood cells. Cytotoxicity at the early stage was investigated on twenty types of polymers (positively charged, negatively charged, or neutral) and ten combination forms via hemolysis, cell viability, and AnnexinV-FITC/PI staining assays. We determined their effects on the cell membrane depending on their surface chemistry by molecular dynamics simulations. Furthermore, the toxicity of LbL-assembled nanofilms was assessed by measuring cell viability. Based on this report, researchers can produce nanofilms that are better suited for drug delivery and biomedical applications by reducing the possible cytotoxicity.
DC plasma‐polymerization of pyrrole: Comparison of films formed on anode and cathode (1996)

Thin films of plasma-polymerized pyrrole were deposited on stainless steel substrates from a parallel-plate DC reactor. They were characterized by XPS, 1H-NMR, STM, cyclic voltammetry, and by reflection-absorption infrared (RAIR) and UV-VIS spectroscopy. The films simultaneously formed on the anode and the cathode were compared. Substantial differences were found between the structures of these films, although their overall compositions were very similar. The films on the anode appeared to be less crosslinked and contained less unsaturation and conjugation than the films on the cathode. The observed effects are explained in a model in which the concurrent positive ion bombardment plays an important role in modifying the structure of a growing plasma-polymerized film. © 1996 John Wiley & Sons, Inc.
A low complex energy saving access algorithm based on base station sleep mode (2013)

The traffic of wireless networks changes in time and spatial distribution. When the traffic load is low, some base stations (BSs) can be sleep mode even been turned off to improve system energy efficiency, the corresponding traffic can be provided by the rest active base stations. In this paper, firstly, considering users with different locations and Quality of Service (QoS) requirements in actual cellular networks, an energy consumption problem is formulated. Secondly, a mobile station round robin base stations (MSRRBS) access algorithm is presented based on base station sleep mode when the network traffic load is low. At last, the computation complexity analysis is given compared to exhaustive search (ES) method. Simulation results show that, the MSRRBS algorithm can significantly reduce the total energy consumption of the network with low traffic load, meanwhile it almost achieves the nearly same performance with the ES method. Three sleep scenarios are considered, it is shown that the sleep scenario is also crucial for BSs sleep design.
Beyond the Green: Understanding the Evolutionary Puzzle of Plant and Algal Cell Walls (2010)

Niklas (2000) defined plants as “photosynthetic eukaryotes,” thereby including brown, red, and green macroalgae and microalgae. These groups share several features, including the presence of a complex, dynamic, and polysaccharide-rich cell wall. Cell walls in eukaryotes are thought to have evolved by lateral transfer from cell wall-producing organisms (Niklas, 2004). Green and red algae originate from a primary endosymbiotic event with a cyanobacterium, which is thought to have occurred over 1,500 million years ago (Palmer et al., 2004). Even though extant cyanobacteria have cell walls that are based on a peptidoglycan-polysaccharide-lipopolysaccharide matrix and thus differ markedly from the polysaccharide-rich cell walls of plants, there is preliminary evidence that they may contain some similar polysaccharides (Hoiczyk and Hansel, 2000), and genes already involved in polysaccharide synthesis or those subsequently coopted into wall biosynthesis may have been transferred during endosymbiosis. Independent secondary endosymbiotic events subsequently gave rise to the Euglenozoa (which lack cell walls) and brown algae (which have cell walls; Palmer et al., 2004). Investigations of the diversity of wall composition, structure, and biosynthesis that include algae, therefore, may lend new insights into wall evolution (Niklas, 2004).
Tunable Topological Acoustic Tamm States in Comblike Structures Based on Band Inversion around Flat Bands (2022)

We investigate the existence of acoustic Tamm states at the interface between two one-dimensional (1D) comblike phononic crystals (PnCs) based on slender tubes and discuss their topological or trivial character. The PnCs consist of stubs grafted periodically along a waveguide and the two crystals differ by their geometrical parameters (period and length of the stubs). We use several approaches to discuss the existence of Tamm states and their topology when connecting two half-crystals. First, we derive a necessary and sufficient condition on the existence of interface states based on the analysis of the bulk band structure and the symmetry of the band edge states. This approach is equivalent to an analysis of the Zak phases of the bulk bands in the two crystals. Indeed, a topological interface state should necessarily exist in any common bandgap of the two PnCs for which the lower (upper) band edges have opposite symmetries. A novelty of our structure consists in the fact that the symmetry inversion results from a band closure (flat band) rather than from a gap closure, in contrast to previous works. Then, such interface states are revealed through different physical quantities, namely: (i) the local density of states (LDOS), which exhibits a high localization around the interface; (ii) sharp peaks in the transmission spectra in the common bandgap when two finite crystals are connected together; (iii) the phases of the reflection coefficients at the boundary of each PnC with a waveguide, which have a direct relationship with the Zak phases. In addition, we show that the interface states can transform to bound states in the continuum (BICs). These BICs are induced by the cavity separating both PnCs and they remain robust to any geometrical disorder induced by the stubs and segments around this cavity. Finally, we show the impossibility of interface states between two connected PnCs with different stub lengths and similar periods. The sensitivity of these states to interface perturbations can find many practical applications in PnC sensors.

Robust Indoor/Outdoor Detection Method based on Sparse GPS Positioning Information (2018)

Cell phones with GPS function as well as GPS loggers are widely used and we can easily obtain users' geographic information. Now classifying the measured GPS positions into indoor/outdoor positions is one of the major challenges. In this paper, we propose a robust indoor/outdoor detection method based on sparse GPS positioning information utilizing machine learning. Given a set of clusters of measured positions whose center position shows the user's estimated stayed position, we calculate the feature values composed of: positioning accuracy, spatial features and temporal feature of measured positions included in every cluster. Then a random forest classifier learns these feature values of the known data set. Finally, we classify the unknown sequence of measured positions into indoor/outdoor positions using the learned random forest classifier. The experiments demonstrate that our proposed method realizes the F <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sub> measure of 0.9836, which classifies measured positions into indoor/outdoor ones with almost no errors.
An efficient method of antibody elution for the successive or simultaneous localization of two antigens by immunocytochemistry. (1978)

The method described in this paper is available for removal of antibodies retained by tissue antigen after immunohistochemical staining. Its application to the antehypophysis has allowed the successive or the simultaneous localization of two different hormones.
Interactions between Penicillin-Binding Proteins (PBPs) and Two Novel Classes of PBP Inhibitors, Arylalkylidene Rhodanines and Arylalkylidene Iminothiazolidin-4-ones (2004)

Several non-beta-lactam compounds were active against various gram-positive and gram-negative bacterial strains. The MICs of arylalkylidene rhodanines and arylalkylidene iminothiazolidin-4-ones were lower than those of ampicillin and cefotaxime for methicillin-resistant Staphylococcus aureus MI339 and vancomycin-resistant Enterococcus faecium EF12. Several compounds were found to inhibit the cell wall synthesis of S. aureus and the last two steps of peptidoglycan biosynthesis catalyzed by ether-treated cells of Escherichia coli or cell wall membrane preparations of Bacillus megaterium. The effects of the arylalkylidene rhodanines and arylalkylidene iminothiazolidin-4-one derivatives on E. coli PBP 3 and PBP 5, Streptococcus pneumoniae PBP 2xS (PBP 2x from a penicillin-sensitive strain) and PBP 2xR (PBP 2x from a penicillin-resistant strain), low-affinity PBP 2a of S. aureus, and the Actinomadura sp. strain R39 and Streptomyces sp. strain R61 DD-peptidases were studied. Some of the compounds exhibited inhibitory activities in the 10 to 100 microM concentration range. The inhibition of PBP 2xS by several of them appeared to be noncompetitive. The dissociation constant for the best inhibitor (Ki = 10 microM) was not influenced by the presence of the substrate.
Visualization of Heterogeneous Data (2007)

Both the Resource Description Framework (RDF), used in the semantic web, and Maya Viz u-forms represent data as a graph of objects connected by labeled edges. Existing systems for flexible visualization of this kind of data require manual specification of the possible visualization roles for each data attribute. When the schema is large and unfamiliar, this requirement inhibits exploratory visualization by requiring a costly up-front data integration step. To eliminate this step, we propose an automatic technique for mapping data attributes to visualization attributes. We formulate this as a schema matching problem, finding appropriate paths in the data model for each required visualization attribute in a visualization template.
Mechanistic Study and Modelling of Precipitation Scale Inhibitor Squeeze Processes (1995)

Abstract A scale inhibitor "precipitation" squeeze is one of the two main types of treatment for preventing downhole scale deposition; the other type is an adsorption squeeze. However, unlike for the adsorption squeeze process, the mechanism for inhibitor retention within the formation through precipitation/re-dissolution is not fully understood and it is this issue that is considered in this work. Here, our central objective is to consider a range of possible models of the precipitation squeeze process and to determine which of these are consistent with the available laboratory core flood and field data. Such models range from pure precipitation through to more complex models which couple the precipitation process with an adsorption process or with a "mechanical transport" phenomenon. The various models are explained in terms of the chemical processes which are observed. Results from two inhibitor precipitation core floods and one field squeeze treatment are presented along with the modelled inhibitor return curves. Based on certain model assumptions, our understanding of the process allows us to optimise the squeeze design of both inhibitor solution and operational parameters for extending the precipitation squeeze life time.
Dolor en niños: cómo evaluarlo y tratarlo eficazmente (2010)

Resumen El dolor es definido como una experiencia emocional desagradable y como tal depende de vivencias previas que van incluso desde el segundo trimestre de gestacion, cuando todos los mecanismos centrales encargados de la percepcion del dolor estan desarrollados. Eso solo se traduce en que el nino siente dolor y debemos estar preparados para evaluarlo y tratarlo eficazmente. En los ninos menores de 2 anos que no se comunican verbalmente, le evaluacion del dolor es fisiologica derivada de su respuesta del estres (taquicardia, taquipnea y sudoracion palmar) y, lo mas importante, la expresion facial que es el estandar de oro en la evaluacion del dolor en menores de 7 anos. Palabras clave: Analgesia en ninos, manejo farmacologico, morfina, analgesia regional.
Performance Analysis of an Autonomous Mobile Robot Mapping System for Outdoor Environments (2006)

As unmanned ground vehicles take on more and more intelligent tasks, determination of potential obstacles and accurate estimation of their position become critical for successful navigation and path planning. The performance analysis of obstacle mapping and unmanned vehicle positioning in outdoor environments is the subject of this paper. Recently, the National Institute of Standards and Technology's (NIST) Intelligent Systems Division has been a part of the Defense Advanced Research Project Agency LAGR (Learning Applied to Ground Robots) Program. NIST's objective for the LAGR Project is to insert learning algorithms into the modules that make up the NIST 4D/RCS (Four Dimensional/Real-Time Control System) standard reference model architecture which has been successfully applied to many intelligent systems. We detail world modeling techniques used in the 4D/RCS architecture and then analyze the high precision maps generated by the vehicle world modeling algorithms as compared to ground truth obtained from an independent differential GPS system operable throughout most of the NIST campus. This work has implications, not only for outdoor vehicles but also, for indoor automated guided vehicles where future systems will have more and more onboard intelligence requiring non-contact sensors to provide accurate vehicle and object positioning
Microelectromechanical systems: interfacing electronics to a non-electronic world (2002)

Microelectromechanical systems (MEMS) merging integrated sensors, microactuators, and low-power electronics are rapidly growing in sophistication. Projection displays, IR/thermal imagers, print heads, microphones, accelerometers and gyros are all emerging based on this technology. Using embedded microprocessors, complete microsystems employing self-testing and digital compensation promise to achieve levels of reliability and accuracy previously impossible at low cost. Sensors for advanced semiconductor process tools, modules for distributed environmental monitoring, inertial-grade navigation aids, advanced security systems, and mass storage devices are a few of the applications being targeted. The technology choices, device structures, applications, and tradeoffs in this area are examined in this paper along with future challenges.
The impact of luteinizing hormone in assisted reproduction: a review (2007)

Luteinizing hormone levels, as a component of the follicle-stimulating hormone: luteinizing hormone ratio, contribute to the assessment of ovarian function, whereas the supplementation of luteinizing hormone on an individualized basis, in carefully selected patients, improves outcomes of ovarian stimulation with gonadotropins.
Oxidation Behavior of Tantalum Boride Ceramics (2007)

The oxidation behavior of tantalum diboride (TaB2) powder at high temperature was investigated in order to determine the possibility of the use of advanced high temperature structural materials. Unfortunately, monolithic TaB2 were known to be chemical stability up to high temperatures. To date, there have been few reports regarding the properties of TaB2 ceramics. The samples were oxidized at room temperature to 1273 K for 5 minutes to 25 hours in air. The weight changes were measured to estimate the oxidation resistance. The oxidation of samples oxidized for short oxidation time of 5 minutes started at 873 K, and the weight gain increased with increasing oxidation temperature. On the other hand, at the oxidation time of above 1 hour, a maximum weight gain value at 973 to 1073 K was observed. However, even if the oxidation temperature was increased an additional weight change slightly occurred. The weight gain of the sample oxidized at 1273 K for 5 minutes to 25 hours was about 40 to 20 % of the theoretical oxidation mass change. According to the powder X-ray diffraction date, the oxidized TaB2 sample was changed to Ta2O5 at 873 K. Finally, the TaB2 showed a good oxidation resistance at high temperature, because the surface film of tantalum oxide (Ta2O5) formed by oxidation acted as an oxidation resistant layer.
Night-Time Electromechanical Activation Time, Pulsatile Hemodynamics, and Discharge Outcomes in Patients with Acute Heart Failure (2015)

Modern concepts in the treatment of chronic lymphocytic leukemia (2009)

There has been considerable progress in the treatment of chronic lymphocytic leukemia (CLL) during last 10 years. Purine analogs and monoclonal antibodies have enabled the shift from purely palliative treatment to intensive regimens aiming at complete remissions and possible prolongation of survival. Many patients have now been shown to achieve molecular responses in addition to their hematological remission. Despite this success, virtually all patients with CLL will eventually relapse and will become refractory to treatment. Allogeneic stem cell transplantation offers a chance of definite cure but is feasible in a minority of patients only. Therefore, considerable effort has been devoted to the further development of more conventional CLL management that is applicable to patient population generally affected by the disease. Emerging treatment concepts include novel combination of well-know agents such as rituximab and chlorambucil, fludarabine, cyclophosphamide and alemtuzumab, FCR with mitoxantrone amongst many. Consolidation regimens using mainly alemtuzumab are also increasingly used but are associated with a major increase in severe infections. High-dose steroids in combination with rituximab or alemtuzumab represent a promising option for refractory patients. Modern chemoimmunotherapy with the FCR regimen has also been tested in early stage patients with unfavourable prognostic factors. Finally, a there are a wide variety of novel drugs including bendamustine, a unique cytostatic with combined properties of an alkylating agent and purine analog, the monoclonal antibodies anti-CD20 ofatumumab and the anti-CD23 lumiliximab, thalidomide and its analog lenalidomide, the semi-synthetic flavonoid flavopiridol and other agents which are currently undergoing clinical trials with promising results. This article reviews the recent advances and future possibilities in the treatment of CLL.
