Mobile Reception of Digital AM Audio and Data Services Using Long-Range Skywave Propagation (2007)

Digitization of AM radio systems promises a revival of the currently underutilized broadcasting bands below 30 MHz. Its prospects are near-FM sound quality, automatic tuning, and interference-free reception. Using skywave propagation in some of the bands, a potentially very large area can be covered by a single transmitter if the appropriate frequency and power are chosen. In this paper, we compare mobile and stationary reception at various frequencies, investigate the correlation between solar sunspot activity and reception quality, and analyze how non-audio data service can efficiently be broadcast with digital radio systems in the AM bands. Restrictions regarding the antenna size together with varying ionospheric conditions and and man-made noise make the reception of radio transmissions below 30 MHz in a car a challenging problem. Using the Digital Radio Mondiale (DRM) system, a total of 58 measurements were conducted both in rural and urban environments in fall 2005, most of them in the 49 m, 41 m and 17 m short wave bands, but also in long wave and medium wave bands. A stationary reference receiver recorded data of the same transmission in parallel with the mobile measurements. Comparison of both data sets allowed for a detailed analysis of the impact of mobility on the reception quality. The results show that particularly in rural areas, mobile reception is indeed reliable and perceived as high quality. Only when ionospheric disturbances push signals to just above the required Signal-to-Noise Ratio (SNR), in-car reception fades more frequently than at a stationary receiver. In urban and industrial areas, shadowing effects (tunnels, large buildings) and man-made noise (power lines, etc.) cause even more frequent dropouts. Thus most of the problems known from analog AM reception in cars will remain the same for digital broadcasting. However, where it works, the digital audio quality is clearly superior to that of analog AM. Therefore, we believe that digital radio in the AM bands is a valuable complement to other digital broadcast services, e.g. by augmenting their coverage in rural areas, where network deployments for higher frequencies may economically not be feasible. Further, the data features-although limited-make digital broadcasting in the AM bands an interesting candidate for telematics and traffic information services covering very large areas.

Immobilized microbial cell biocatalysts (2021)

This special issue in the journal Catalysts has an extensive collection of articles on the immobilization of enzymes and microbial cells that are expressing key specific enzymes. This review provides a good coverage of microbial cell immobilization methods and provides industrial examples. This paper describes a layer-by-layer encapsulation approach that can be used as part of a whole cell immobilization process. Microbial cell immobilization can happen naturally, as in a biofilm, or via an engineered process. This paper reviews what is known about the metabolic state of viable immobilized cells. This immobilization method is a variation of the whole-cell theme. The study explored whole cell enzyme expression, along with expression of a phage lytic process that allows enzyme leakage and subsequent immobilization. This commercial website briefly describes the steps in whole cell biocatalyst develop, including surface expression of enzymes. While many biocatalytic reactions are performed in aqueous media, it is often desirable, or even necessary, to conduct the biotransformation reactions in organic solvents. This article reviews some of the issues involved in whole cell biocatalysis in organic solvents. Actinobacteria are responsible for producing most of the known natural products and are important in waste chemical degradation. This paper focuses more on the biocatalysis aspect of the bacteria rather than methodologies. This slide set offers a general primer on whole cell immobilization. Traditionally, wine making has used unattached cells in the juice undergoing fermentation. This study explored the use of immobilized cell processes for winemaking. Most often, microbial cell immobilization is performed with a single pure culture. However, it can be advantageous to combine microbes with different metabolic capabilities and this paper deals with cell immobilization technology to enhance coculture biotransformations. This review deals with patents on immobilizing materials and use of immobilized cells in bioreactors. This review discusses methods for sensing signals and for fabricating microbial structures and materials for biosensor manufacture. This web protocol discusses one facet of microbial cell immobilization. In general, cells can be covalently attached to a support, adsorbed, or entrapped within a matrix. This review deals with the latter.
An active AMC ground plane for tunable low-profile antennas (2008)

We have designed an active Artificial Magnetic Conductor able to change its resonance by varying the diode polarization. This type of surface has been employed as backing plane for a bow-tie radiating element in order to synthesize a tunable and steerable antenna. The AMC allows to obtain a thin structure with a thickness equal to lambda/24, able to dynamically change impedance matching frequency. Moreover, the possibility of performing a beam scanning has been shown in correspondence of the mid-band frequency.

Does acute pancreatitis herald pancreatic ductal adenocarcinoma? A multicenter electronic health research network study (2022)

AP is infrequently associated with PDAC and can precede a diagnosis of PDAC in a minority of patients without another known etiology of pancreatitis. Patients with a recent AP are more likely to undergo surgical resection of PDAC and a trend toward diagnosis at an earlier stage compared to patients with PDAC and without AP. The impact of AP-related PDAC on survival is unknown.
Expansion of Stacking Faults in 4H-SiC Epitaxial Layer under Laser Light Excitation during Room Temperature Photoluminescence Mapping (2008)

We investigated the expansion of single Shockley stacking faults (SSFs) in a 4H-SiC epitaxial layer under high-intensity scanning laser beam during room temperature photoluminescence mapping, which is similar to the degradation of bipolar pin diodes during forward current injection. In an epitaxial layer on an 8 off-axis (0001) substrate, the SSF-related intensity patterns induced by scanning high-intensity laser beam were classified into two types. The first one was a triangular pattern and the second a pattern which expanded in accordance with the motion of the scanning laser beam. The origins of the SSFs responsible for both patterns are presumably due to the preexisting basal plane dislocations and the dislocation-loops on the basal plane in the epitaxial layer, respectively. On the other hand, most of the SSF-expansion in on-axis (11 2 0) epitaxial layers were similar to the second type in the (0001) epitaxial layer. We, therefore, suggest that the dislocation-loops, which were located close to the surface, were dominant nucleation-sites of the SSFs in the (11 2 0) epitaxial layers.
Field Theory Design of Square Waveguide Iris Polarizers (1986)

Profiled depth corrugated square waveguide polarizers are designed with the method of field expansion into eigenmodes, which includes higher order mode interaction between the step discontinuities. Computer-optimized design data are giyen for a compact Ku-band prototype with an exponentially varying depth function that achieves 90° +- 1° differential phase shift shift within the separate 11.9-12.3-GHz and 17.5-17.9-GHz frequency bands. The maximum VSWR is only about 1.02. Further design examples include a linearly profiled depth function, which provides a short design, and a polarizer with iris thicknesses suitable for metal-etching manufacturing technique. The theory is verified by comparison with available measured results.
Motivation for Rehabilitation in Patients With Subacute Stroke: A Qualitative Study (2021)

<b>Background:</b> Motivation is essential for patients with subacute stroke undergoing intensive rehabilitation. Although it is known that motivation induces behavioral changes toward rehabilitation, detailed description has been lacking. Motivation can be intrinsic or extrinsic; however, it is unclear which type of factors mainly motivates patients' daily rehabilitation. <b>Purpose:</b> This study aimed to examine the factors influencing patients' motivation and to explore the behavioral changes induced by motivation, especially age-related differences. <b>Method:</b> Twenty participants (mean age 65.8 years [standard deviation 13.7]) who had a subacute stroke and underwent rehabilitation at a convalescent hospital were recruited using convenience sampling. Semi-structured interviews were conducted by an occupational therapist with an interview topic guide regarding factors influencing motivation and how it affects behavioral change. Interviews were recorded, transcribed to text, and analyzed by three occupational therapists using thematic analysis. The participants were divided into two groups: aged patients (aged ≥ 65 years) and middle-aged patients (aged < 65 years), and data were analyzed according to the groups. This study was conducted according to the consolidated criteria for reporting qualitative research. <b>Results:</b> Seven core categories were identified as factors influencing patients' motivation: patients' goals, experiences of success and failure, physical condition and cognitive function, resilience, influence of rehabilitation professionals, relationships between patients, and patients' supporters. The first four and last three core categories were further classified as personal and social-relationship factors, respectively. The categories related to intrinsic motivation such as enjoyment of rehabilitation itself were not derived. In both age-groups, motivation affected the frequency of self-training and activity in daily lives. In some aged patients, however, high motivation restrained their self-training to conserve their physical strength for rehabilitation by professionals. Some aged patients do not express their high motivation through their facial expressions and conversations compared to middle-aged patients; therefore, motivation is not always observable in aged patients. <b>Conclusions:</b> Interventions tailored to extrinsic factors are important for maintaining patients' motivation. Observational evaluation may lead to mislabeling of their motivation, especially for aged patients. Rehabilitation professionals should use validated evaluation scales or patients' narratives to assess patients' motivation.
Liquid and Gas Distribution in Trickle-Bed Reactors (1996)

Liquid and gas distribution in trickle-bed reactors was investigated in a column packed with commercial catalyst particles. Distilled water and air were used as liquid and gas phases, respectively. Surface tension effects were tested by adding detergent to the water. The influence of both liquid load and gas load on the distribution was studied. Flow rates corresponded to those used in industrial hydroprocessing units. It was found that the liquid distribution at a given liquid load can be improved considerably by either increasing the liquid load or flooding the column in advance. The gas distribution is shown to be correlated inversely with the liquid distribution. Use of a large-particle top layer results in an improved distribution.
Total Synthesis and Configurational Assignment of the Marine Natural Product Haliclamide (2013)

The marine natural product haliclamide has been synthesized based on macrocyclization by ring-closing olefin metathesis. Using either enantiomer of two of the four building blocks that were employed to assemble the diene precursor for the metathesis reaction, three non-natural isomers of haliclamide were also prepared. On the basis of the comparison of the (1)H and (13)C NMR spectra of the individual stereoisomers with literature data for the natural product, the configuration of the previously unassigned stereocenters at C9 and C20 of haliclamide could be determined to be S for both carbons. The absolute configuration of haliclamide thus is 2S, 9S, 14R, 20S. The antiproliferative activity of synthetic haliclamide against several human cancer cell lines was found to be in the high μM range. The compound showed no antifungal or antibiotic activity.
Simulations of high disruption colliding beams (1990)

Recent B-factory proposals that use a linac beam colliding with the beam from a storage ring to achieve high luminosities (L > 10{sup 34} cm{sup {minus}2}sec{sup {minus}1}) result in very high disruption of the linac beam. The effects of such high disruption have been studied using the relativistic, 3-D code SWARM. We discuss the assumptions, parameters, and results of a series of runs that model such collisions. Regimes of high beam loss and methods to avoid them are also discussed. 5 refs., 4 figs.
Indaconitine 0.5-acetonitrile solvate (1999)

The crystal structure of indaconitine hemiacetonitrile solvate, [1α,6α,14α(E),16β]-20-ethyl-1,6,16-trimethoxy-4-methoxymethyl-3,13-dihydroxyaconitane-8,14-diyl 8-acetate 14-benzoate hemiacetonitrile solvate, C 34 H 47 NO 10 .0.5C 2 H 3 N, a C 19 norditerpenoid alkaloid isolated from the roots of Aconitum chasmanthum Stapf ex Holmes of Pakistani origin, contains a molecule of the alkaloid and half a molecule of the solvate in an asymmetric unit. The molecular dimensions are as expected. The fused ring system contains one boat, one half-chair, two chair and two envelope conformations. The crystal structure is stabilized by an intermolecular hydrogen bond between indaconitine and acetonitrile, with an O…N distance of 3.036 (6) A. An hydroxyl group is also involved in an intramolecular interaction with a methoxy group, with an O…O separation of 2.643 (5) A.

Development and Scale-Up of Cocrystals Using Resonant Acoustic Mixing (2014)

In the present work resonance acoustic mixing was applied to afford a practical and environmentally friendly approach to produce and scale up cocrystals. Scale-up options for producing cocrystals are limited. Solution-phase cocrystallizations, although amenable to scale-up in stirred tanks, may be limited due to multiple solubility constraints on both coformers and the product cocrystals, resulting in challenges to find feasible processing conditions. While mechanochemical methods such as liquid-assisted grinding (LAG), solid drop grinding (SDG), and ball-milling have been shown to be more general than solution-phase methods, they are also more difficult and impractical to scale up. In the present work a resonant acoustic mixer was used to intimately mix active pharmaceutical ingredient (API) compound and coformer at high frequency, in the presence of a small amount of solvent, to induce conversion to cocrystals with no grinding media required. Carbamazepine (CBZ) and nicotinamide (NCT) were used as a model system for successfully producing CBZ:NCT cocrystals. Thus, it was shown that resonant acoustic mixing provides the mixing intensity required of lab-scale mechanochemical methods, such as liquid -assisted grinding, but now on a platform more amenable to larger-scale manufacture. Resonant acoustic mixing in general has been demonstrated to be scalable to volumes greater than 200 L and thus affords a potential new platform for cocrystallization processes.
Algerian Pearl Millet (Pennisetum glaucum L.) Contains XIP but Not TAXI and TLXI Type Xylanase Inhibitors (2009)

An XIP (xylanase inhibiting protein) type xylanase inhibitor was purified from Algerian pearl millet ( Pennisetum glaucum L.) grains and characterized for the first time. Cation exchange and affinity chromatography with immobilized Trichoderma longibrachiatum glycoside hydrolase (GH) family 11 xylanase resulted in electrophoretically pure protein with a molecular mass of 27-29 kDa and a pI value of 6.7. The experimentally determined N-terminal amino acid sequence of the purified XIP protein is 87.5%, identical to that of sorghum ( Sorghum bicolor L.) XIP and 79.2% identical to that of wheat ( Triticum aestivum L.) XIP-I. The biochemical properties of pearl millet XIP are comparable to those described earlier for sorghum XIP, except for the higher specific activity toward a T. longibrachiatum GH family 11 xylanase. On the basis of immunoblot neither TAXI nor TLXI type xylanase inhibitors were detected in pearl millet grains.
Multiprogramming on multiprocessors (2002)

Many solutions have been proposed to the problem of multiprogramming a multiprocessor. However, each has limited applicability or fails to address an important source of overhead. In addition, there has been little experimental comparison of the various solutions in the presence of applications with varying degrees of parallelism and synchronization. The authors explore the tradeoffs between three different approaches to multiprogramming a multiprocessor: time-slicing, coscheduling, and dynamic hardware partitions. They implemented applications that vary in the degree of parallelism, and the frequency and type of synchronization. They show that in most cases coscheduling is preferable to time-slicing. They also show that although there are cases where coscheduling is beneficial, dynamic hardware partitions do no worse, and will often do better. They conclude that under most circumstances, hardware partitioning is the best strategy for multiprogramming a multiprocessor, no matter how much parallelism applications employ or how frequently synchronization occurs.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Supramolecular structure of perylene tetracarboxdiimides (2008)

Abstract Using atomistic molecular dynamics (MD) simulations we study the columnar phases of perylene tetracarboxdiimides (PDI) and establish correlations between the molecular structure, packing, and dynamical properties of these materials. Combining electronic structure calculations, MD and kinetic Monte Carlo simulations, a correlation is then established between molecular structure and charge mobility of columnar mesophases of perylene tetracarboxdiimide derivatives.

How to turn the page [digital libraries] (2004)

Can digital libraries provide a reading experience that more closely resembles a real book than a scrolled or paginated electronic display? We describe a prototype page turning system that realistically animates full three-dimensional page-turns. The dynamic behavior is generated by a mass-spring model defined on a rectangular grid of particles. The prototype takes a PDF or e-book file, renders it into a sequence of PNG images representing individual pages, and animates the page-turns under user control. The simulation behaves fairly naturally, although more computer graphics work is required to perfect it.

An alternative solder interconnect reliability test to evaluate drop impact performance (2008)

With the increased use of mobile phones, navigation systems, PDA's, laptop's and portable gaming devices the drop reliability of microelectronics has become an important parameter. Assessing the solder interconnect quality by means of drop impact testing, as standardized by e.g. JEDEC, during normal production requires considerable amounts of time and effort. Besides this, the repeatability of the drop impact test is low and introduces elaborate and time-consuming analysis of the results after testing. Already many researchers have investigated new test techniques capable of replacing the drop impact test, e.g. high-speed shear, pull and bending. Among those tests is the High Speed Cold Bump Pull test (HSCBP or CBP). In the CBP test the solder bump is pulled in vertical direction from the die using a small pair of jaws. In this test, by varying the pull speed several different strain-rates can be applied to the solder bump. In our research a correlation between the drop impact test and cold bump pull test is investigated. This can be divided into three parts. First by investigating the cold bump pull test apparatus for uncontrolled parameters that might introduce a bias or spread in the results. Secondly by means of modeling the cold bump pull test to investigate solder bump deformation and solder bump loading during pull off. Finally the differences and similarities between the drop impact test and the cold bump pull test are briefly discussed and some observations concerning the solder joint performance are presented.
