A spectrum-overlapped resource management in dynamic spectrum control technique (2008)

This paper proposes a spectrum-overlapped resource management (SORM) technique using a dynamic spectrum control (DSC) and turbo equalizer for flexible frequency domain resource management under multiuser conditions. In the proposed technique, discrete spectrum of the transmitted signal is mapped onto spectrum components having the highest channel gain in the system band while accepting partial spectrum overlapping between users, and a frequency domain soft-canceller with minimum mean square error (FD-SC/MMSE) turbo equalizer is applied as the signal detection scheme for multiuser detection (MUD) in order to cancel not only inter-symbol interference (ISI) but also inter-user interference (IUI). Computer simulation including extrinsic information transfer (EXIT) analysis confirms that the proposed scheme can achieve high frequency selection diversity and realize flexible frequency domain resource management.
New approaches to invasive fungal infections (2003)

Invasive fungal infections are typically difficult to prevent, diagnose, and treat; consequently, fungal infection-related mortality has become high, particularly among patients with prolonged neutropenia and severe graft-versus-host disease. However, much recent progress has been made in understanding the immune response to fungi and the epidemiology of infection, and new diagnostic tests and antifungal drugs have become available. This review will describe these most recent developments with the goal of evaluating new approaches to prevent, diagnose, and treat invasive fungal infections.
Genome protecting and genotoxic effects produced by derivatives of 1,4-dihydropyridine (2022)

The review summarizes data on genome protecting and genotoxic action of 1,4-dihydropyridines (DHP) with main focus on the compounds synthesized in the Latvian Institute of Organic synthesis. Most of these compounds manifest very low calcium channel blocking activity, thus considered to be “unusual” 1,4-DHP. Some of these compounds decrease spontaneous mutagenesis and frequency of mutations induced by chemical mutagens. Some water-soluble 1,4-DHP protect DNA against damage produced by hydrogen peroxide, radiation and peroxynitrite. In these molecules capability to protect DNA cohabitates with DNA-binding activity. Possible mechanisms of above effects are discussed.
Antiulcerogenic Effects ofOcimum basilicumExtracts, Volatile Oils and Flavonoid Glycosides in Albino Rats (1992)

Antiulcerogenic effects of extracts, volatile oils and flavonoid glycosides of Ocimum basilicum leaves were studied in normal as well as aspirin-, acetic acid- and stress-induced ulcerated rats. Also, their effects on outputs of gastric acid, pepsin and hexosamines were recorded in normal and ulcerated rats. The aqueous, methanol and water-methanol extracts and flavonoid glycosides of O. basilicum decreased the ulcer index, inhibited gastric acid and pepsin secretions and enhanced hexosamines in aspirin-treated rats. The aqueous extract increased glucosamine but did not affect the output of acid and pepsin. The methanol extract lowered acid and pepsin output but did not increase the glucosamine level. However, the water-methanol extract decreased acid output, increased glucosamine, and did not affect pepsin. The flavanoid glycosides of O. basilicum decreased the ulcer index and the outputs of acid and pepsin, but increased glucosamines. Volatile oils of the plant were ineffective against stress-induced ulcers. However, high antiulcer activity was demonstrated by the aqueous extract in acetic acid-induced ulcerated rats. It therefore appears that anti ulcerogenic activity of O. basilicum is extractable into both water and methanol and its active principle(s) may include flavonoid glycosides. These substances may act by augmenting the gastric barrier.
UNO: Static Source Code Checking for User-Defined Properties 1 (2002)

Only a small fraction of the output generated by typical static analysis tools tends to reveal serious software defects. Finding the important defects in a long list of warnings can be a frustrating experience. The output often reveals more about the limitations of the analyzer than about the code being analyzed. There are two main causes for this phenomenon. The first is that the typical static analyzer casts its nets too broadly, reporting everything reportable, rather than what is likely to be a true bug. The second cause is that most static analyzers can check the code for only a predetermined, fixed, set of bugs: the user cannot make the analyzer more precise by defining and experimenting with a broader range of application-dependent properties. We describe a source code analyzer called UNO that tries to remedy these problems. The default properties searched for by UNO are restricted to the three most common causes of serious error in C programs: use of uninitialized variables, nil-pointer dereferencing, and out-of-bound array indexing. The checking capabilities of UNO can be extended by the user with the definition of application-dependent properties, which can be written as simple ANSI-C functions.
Texture and edge preserving multiframe super‐resolution (2014)

Super‐resolution (SR) image reconstruction refers to methods where a higher resolution image is reconstructed using a set of overlapping aliased low‐resolution observations of the same scene. Although edge preservation has been a widely explored topic in SR literature, texture‐specific regularisation has recently gained interest. In this study, texture‐specific regularisation is handled as a post‐processing step. A two stage method is proposed, comprising multiple SR reconstructions with different regularisation parameters followed by a restoration step for preserving edges and textures. In the first stage, two maximum‐a‐posteriori estimators with two different amounts of regularisation are employed. In the second stage, pixel‐to‐pixel difference between these two estimates is post‐processed to restore edges and textures. Frequency selective characteristics of discrete cosine transform and Gabor filters are utilised in the post‐processing step. Experiments on synthetically generated images and real experiments demonstrate that the proposed methods give better results compared with the state‐of‐the‐art SR methods especially on textures and edges.
Historical aspects of interventional cardiology: past, present and future. (1986)

The purpose of this presentation is to report the progress of two interventional catheter techniques that have occupied my attention for the last 10 years; namely, transcatheter patent ductus arteriosus occlusion and patch atrial septal defect closure. A brief survey of the aspects of interventional cardiology, including its past, present and future, will also be included.
Rapid code acquisition algorithm employing PN matched filters (1988)

The performance of four algorithms using pseudonoise matched filters (PNMFs), for direct-sequence spread-spectrum systems, is analyzed. They are: parallel search with fix dwell detector (PL-FDD), parallel search with sequential detector (PL-SD), parallel-serial search with fix dwell detector (PS-FDD), and parallel-serial search with sequential detector (PS-SD). The operation characteristic for each detector and the mean acquisition time for each algorithm are derived. All the algorithms are studied in conjunction with the noncoherent integration technique, which enables the system to operate in the presence of data modulation. Several previous proposal using PNMF are seen as special cases of the present algorithms.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

Stereological analysis of thermally sprayed deposits (1995)

Thermal spray deposits can be described by several characteristics including the porosity, the fraction of unmolten particles and the microhardness. These physical and structural characteristics are general and little quantitative information is available to fully describe the microstructure of such deposits. Stereological analysis is one of the microscopic methods which provides quantitative relationships. Hence, it allows a better understanding of correlations between spray parameters and deposit microstructure. Stereology, in the most strict sense, is able to describe a 3-D space from 2-D sections through solid bodies. The aim of this paper is to review the numerical formulations of methods that can be applied on 2-D cross-sections of thermal spray deposits. A historical perspective of several approaches is given, and two methods (i.e., DeHoff`s and Cruz-Orive`s protocols) are detailed.
Blinding is compromised for transcranial direct current stimulation at 1 mA for 20 minutes in young healthy adults (2018)

Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation method that is frequently used to study cortical excitability changes and their impact on cognitive functions in humans. While most stimulators are capable of operating in double-blind mode, the amount of discomfort experienced during tDCS may break blinding. Therefore, specifically designed sham stimulation protocols are being used. The "fade-in, short-stimulation, fade-out" (FSF) protocol has been used in hundreds of studies and is commonly believed to be indistinguishable from real stimulation applied at 1 mA for 20 minutes. We analyzed subjective reports of 192 volunteers, who either received real tDCS (n=96) or FSF tDCS (n=96). Participants reported more discomfort for real tDCS and correctly guessed the condition above chance-level. These findings indicate that FSF does not ensure complete blinding and that better active sham protocols are needed.
Laser generated microstructures in tape cast electrodes for rapid electrolyte wetting: new technical approach for cost efficient battery manufacturing (2014)

Three-dimensional (3D) battery architectures are under current scientific investigation since they can achieve large areal energy capacities while maintaining high power densities. A main objective of surface patterning is the enhancement of lithium-ion diffusion which is often a limiting factor in lithium-ion cells. By using a rather new approach, laser material processing of thick-film electrodes has been investigated for the precise adjustment of 3D surface topography. Besides lithium-ion diffusion in electrode materials as an electrochemically limited process, a critical step in lithium-ion pouch cell manufacturing is the homogeneous electrolyte wetting of stacked electrodes and separators. This process requires cost expensive and time-consuming vacuum and storage processes at elevated temperatures. A new and cost efficient laser process has been successfully applied in order to significantly improve the electrode wetting and the battery operation. Preliminary investigations for testing the process on pouch cell geometry revealed higher capacities and increased cell life-time compared to standard cells without storage processes at elevated temperatures. The laser structuring process can be applied to commercial electrode materials and integrated into existing production lines.
DIGITAL DOCUMENTATION AND THE DENTAL OPERATING MICROSCOPE: WHAT YOU SEE IS WHAT YOU GET (2009)

The importance of regular digital photography and documentation in the dental office cannot be understated. The many uses for documentation include publication, diagnosis and treatment planning, dentolegal documentation, forensic documentation, insurance verification, patient education, marketing, and communication with laboratories, dental team members, and colleagues. With the introduction of the dental operating microscope into dental treatment, the ease and scope of documentation have been drastically improved. Images and video taken with the microscope can show details that would not be visible with conventional photography. The aim of this article is to provide an overview of the equipment and techniques available to achieve high-quality digital documentation using an operating microscope. INT J MICRODENT 2009;1:30–41
Characterization of new aromatic polymers for 157-nm photoresist applications (2001)

There is currently tremendous interest in developing 157nm photoresists for imaging applications at 100nm and below. Due to the high VUV absorbance of the polymers used in 248 and 193 photoresists new materials are being investigated for applications at 157nm. In this report the characterization of a number of partially fluorinated polymers based on aromatic backbones will be described. Data on the absorbance, dissolution properties, solvent retention and acid diffusion characteristics of these systems will be presented.
Antigenic Determinants of Influenza Virus Haemagglutinin. VI. Antigenic Characterization of the Oligosaccharide Sidechains from HA1 of Influenza Virus Haemagglutinins (1981)

The oligosaccharide sidechains attached to the major polypeptide, HA1 of the haemagglutinin of influenza virus were examined for antigenic activity using a solid-phase radioimmunoassay. Cross-reactivity between the HA1 of the different human subtypes was clearly demonstrable with IgG raised against purified virus but was abrogated if anti-carbohydrate antibodies were first removed by passage of the IgG through an immunoadsorbent column containing haemagglutinin (HA) from an unrelated avian influenza strain. Antibodies eluted from the column were found to cross-react with the HA1 of all subtypes tested. 'Host antigen' extracted from chick chorioallantoic membrane and coupled to Sepharose was also able to remove cross-reactive antibodies from antiviral sera, while antibodies raised against host antigen bound to the HA1 isolated from each subtype tested. It is concluded that, although there are qualitative and quantitative differences between the oligosaccharide sidechains of influenza haemagglutinins, the antigenically active sidechains are cross-reactive.
Perceptual quality preserving SRAM architecture for color motion pictures (2013)

This work proposes a low power methodology for video framebuffers to preserve the perceptual quality while reducing SRAM power. The bank-wise voltage scaling combined with error masking circuitry is proposed where voltage domains are separated according to the importance of luminous and color channels. The implementation may apply to standard embedded memory cores without redesigning specialized hardware within the SRAM bank. The simulation results showed that the proposed channel protection technique produced better energy-quality trade-off than the conventional higher-order-bit protection for the uncompressed as well as compressed motion image frames.
[Brachytherapy using Ru-106 applicators in ophthalmology]. (1990)

Two Ru-106 applicators of the type CCB as manufactured by the "Zentralinstitut für Isotopen- und Strahlenforschung" (Berlin, GDR) were investigated. The homogeneity of the relative dose distribution at the surface of the applicators was determined. For the evaluation of the data extremely small TLD crystals (2 x 1 x 1 mm) had to be manufactured as well as an almost tissue equivalent acrylic eye phantom. In order to assure reproducibility of the applicator positioning, the plaque suture eyelets had to be placed on locating pins. 120 points of measurements located within the active plaque area of 20 mm diameter were evaluated. The results show that the area to be used in tumor treatment is about 20 to 25% less than expected. One plaque shows a considerable inhomogeneity with respect to dose distribution (up to 40%). A modified eye phantom was used for the determination of the central axis depth dose distribution.
Polytype Inclusions in Cubic Silicon Carbide (2013)

The 3C-SiC layers on nominally on-axis 6H-SiC substrates were grown using sublimation epitaxy. More than 90% coverage by 3C-SiC is typically achieved at growth temperature of 1775°C. The main reason for the polytype inclusions to appear is local supersaturation non-uniformities over the sample surface which appear due to the temperature gradient and spiral growth nature of 6H-SiC. On the 6H-SiC spirals with small steps supersaturation is smaller and 3C-SiC nucleation and growth is diminished. Due to surface free energy and surface diffusion differences, polytype inclusions appear differently when 3C-SiC is grown on the Si- and C-faces. The 6H-SiC inclusions as well as twin boundaries act as neutral scattering centers and lower charge carrier mobility.
Design of Energy Control Method for Three-Phase Buck-Type Rectifier With Very Demanding Load Steps to Achieve Smooth Input Currents (2015)

Conventional three-phase rectifiers are controlled to achieve good power factor and low total harmonic distortion in the input. In the case of pulsating power loads, the fast dynamic response implies that the load pulses are reflected in the generator. These pulsating loads affect the lifetime operation of the generator, especially when it is not oversized (as in the case of aircraft applications). In order to smooth the power demanded from the generator, it is preferable to reduce the bandwidth of the output voltage controller for the rectifier but it affects its stability due to the fact that the right-half-plane (RHP) pole given by the negative impedance of a constant power load requires high-bandwidth control loop to compensate it. In this paper, an energy control method is proposed that utilizes the energy stored in the output capacitor of the rectifier to control the output voltage of the rectifier. In such a way, the minimum bandwidth restriction imposed by the RHP pole of the power load is eliminated and the bandwidth of the voltage loop can be defined low enough to demand smooth power from the generator.
Further Analysis of the Entity-Relationship Approach to Database Design (1981)

The nondeterministic or deterministic entity-relationship model of a database is formaRy defined as a user's view of that database in terms of a collection of time-varying relations: the regular or weak entity relations, or the regular or weak relationship relations. Both nondeterministic and deterministic entity-relationship models have the same strength to characterize information concerning entities and relationships which exist in our minds. An improved table form of the relations is introduced to provide a clear and concise user's view of databases. The basic concept of the entity-relationship approach to the logical database design is provided, and is used to derive 3NF relations. FinaUly, a method of representing physicaly these relations, which are generated by the use of the entity-relationship approach to the logical database design, is presented. Thus, the entity-relationship approach to the logical and physical database design can also be realized.
Update of ASRP: the Arabidopsis Small RNA Project database (2007)

Development of the Arabidopsis Small RNA Project (ASRP) Database, which provides information and tools for the analysis of microRNA, endogenous siRNA and other small RNA-related features, has been driven by the introduction of high-throughput sequencing technology. To accommodate the demands of increased data, numerous improvements and updates have been made to ASRP, including new ways to access data, more efficient algorithms for handling data, and increased integration with community-wide resources. New search and visualization tools have also been developed to improve access to small RNA classes and their targets. ASRP is publicly available through a web interface at http://asrp.cgrb.oregonstate.edu/db/.
The human 1‐8D gene (IFITM2) is a novel p53 independent pro‐apoptotic gene (2009)

The human 1-8 interferon inducible gene family consists of at least 3 functional genes; 9-27, 1-8D and 1-8U, which are all linked on an 18-kb fragment of chromosome 11 and are highly homologous. It has recently been shown by us and others that the 1-8D gene is overexpressed in colon carcinoma. Here, we show, by sequence comparison of the 1-8D in pairs of tumor/normal colon tissues, the existence of 6 different alleles, containing single-nucleotide polymorphisms with no mutations. Transformation assays revealed a possible role for the 1-8D gene as a transformation inhibitor. Further, transient expression of the human 1-8D gene in multiple mammalian cell lines showed accumulation of cells in the G1 phase followed by elevation in the subG1 phase. SubG1 elevation was confirmed as apoptosis by Annexin-V binding assays and transferase-mediated dUTP nick end labeling assays. Moreover, knock-down of 1-8D provided partial protection from Etoposide and UV-induced apoptosis. The induction of apoptosis by 1-8D is dependent on caspase activities but not on p53 expression. Although 1-8D induces apoptosis independently of p53, p53 expression downregulates 1-8D protein expression. Our data suggest a role for the 1-8D gene as a novel pro-apoptotic gene that will provide new insights into the regulated cellular pathways to death.
Ferroelectric Liquid Crystals Having Various Cores. Effect of Core Structure on Physical Properties (1993)

Abstract Ferroelectric liquid crystals (FLC’s) having various cores were synthesized and the effect of the different core structures on the spontaneous polarization (Ps) values was investigated. The results indicate that the core structure has a great influence on the Ps value and introduction of a heterocycles such as pyrimidine and thiadiazole ring in the core increases the Ps value. Moreover, several compounds in this series are interesting as chiral dopants for FLC, because the mixtures containing them showed superior properties as FLC mixture.
A threshold mechanism for distributed query processing (1988)

A strategy to process a distributed query is formed using estimates for partial results sizes and delays/costs associated with the network data transfer and CPU processing. To guard against inaccurate estimates the strategy execution is monitored and if estimates are observed to be “inaccurate” the strategy is corrected. This paper presents and compares two methods which can be used to decide whether or not to correct a strategy. In the Reformulation method a new strategy is formulated after executing each relational operation. The Thresholds method is based on the fact that some partial results formed by the strategy's execution are more “critical” than others. The query processing strategy is represented as a network of activities and the Critical Path Method method is used to determine threshold values for partial results. If a partial result is delayed beyond its threshold value the strategy is corrected. The Reformulation and Thresholds methods are evaluated on a test-bed of queries for a modeled application of a DDB.
