Rechargeable solid state lithium microbatteries (2002)

A rechargeable thin-film lithium battery that can be used as a miniature power supply for small devices has been developed. The battery consists of an amorphous vanadium pentoxide (aV/sub 2/O/sub 5/) cathode, an amorphous lithium phosphorus oxynitride (Lipon) electrolyte, and a lithium anode. A thin-film cover layer protects the battery from exposure to air and water vapor. The battery can deliver up to 60 mu A/cm/sup 2/ of current between 3.6 V and 1.5 V. Higher voltages can be achieved by fabricating two or more cells in series. A 1-cm/sup 2/ cell with a 1-1.5- mu m-thick cathode discharged from 3.6 to 1.5 V at 12 mu A typically yields about 440 mC and delivers about 1 J. Using the combined mass of the cathode, electrolyte, and the anode (3* over capacity), the specific energy of the cell is 1.4*10/sup 6/ J/kg and the energy density is 2.1*10/sup 6/ J/L.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Success-driven learning in ATPG for preimage computation (2004)

Unbounded model checking fundamentally requires either image or preimage calculations. We introduce a hybrid method for making preimage calculations using ATPG and binary decision diagrams (BDDs). Experimental results show that the proposed method achieves a speedup of two to three orders of magnitude over pure ATPG methods.
An Architectural Approach for Self-Managing Security Services (2009)

Self-managing systems are the focus of an increasing research activity since can provide a more robust way of building software artifacts. In this paper, we focus on self-managing systems for adapting the security concern. Providing security as a one-size-fits-all solution results in a system that is far too rigid to accommodate the needs of different application domains. Security mechanisms can depend on the hardware that is available and can be changed over time. Offering a system that can cope with such change without the need of major re-engineering is a major challenge. Moreover, not at all time the same security level has to be maintained. A system that can adapt its security mechanisms to the actual threat level can deliver better performance. In this paper, we provide an architecture for self-adapting the security concern to the actual context. Context is provided in terms of trust and threat values. Moreover, contextual information on resource consumption (e.g., memory and bandwidth) and system status (e.g., availability) can be provided.
Error performance of multiple-symbol differential detection of PSK signals transmitted over correlated Rayleigh fading channels (1992)

The error performance of multiple-symbol differential detection of uncoded QPSK signals transmitted over correlated Rayleigh fading channels is studied. The optimal detector is presented, along with an exact expression for the corresponding pairwise error event probability. It is shown that multiple-symbol differential detection is a very effective strategy for eliminating the irreducible error floor associated with a conventional differential detector. In all of the cases investigated, a detector with an observation interval as small as two symbols is sufficient for this purpose. It is also found that the error performance of a multiple-symbol differential detector is not sensitive to the mismatch between the decoding metric and the channel fading statistics.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
ISSR and AFLP Markers Differ among American Watermelon Cultivars with Limited Genetic Diversity (2004)

Wide phenotypic diversity exists among American heirloom cultivars of watermelon ( Citrullus lanatus var. lanatus ). However, in published studies, low or no polymorphism was revealed among those heirlooms using isozyme or randomly amplified polymorphic DNA (RAPD) markers. In this study, experiments with inter-simple sequence repeat (ISSR) [also known as simple sequence repeat-(SSR-) anchored primers] and amplified fragment-length polymorphism (AFLP) markers produced high polymorphisms among watermelon heirloom cultivars. ISSR (111) and AFLP (118) markers (229 total) identified 80.2% to 97.8% genetic similarity among heirloom cultivars. The phylogenetic relations based on ISSR and AFLP markers are highly consistent with the parental records available for some of the heirloom cultivars, providing confidence in the dendogram constructed for heirlooms based on similarity values. As compared with RAPD markers, ISSRs and AFLPs are highly effective in differentiating among watermelon cultivars or elite lines with limited genetic diversity.
Adaptive resource allocation for Back-end Mashup applications on a heterogeneous private cloud (2010)

On-demand resource provision is one of the key features of cloud computing, allowing applications to grow or shrink on the basis of dynamic workloads. Thus far, most of the research on leveraging on-demand resource provision has focused on batch style applications for scientific computation or Web-centric applications, especially n-tier e-commerce applications. Very little research, however, has focused on leveraging the benefits of cloud computing for applications with alternative architectures. In this paper, we focus on Back-end Mashup applications that have resource-intensive back ends responsible for continuous collection and analysis of real-time data from external services or applications. We present a working prototype back-end mashup application, BuddyMonitor, that allows users of instant messaging services to monitor and analyze the online presence of their “buddies.” The prototype exploits adaptive allocation of cloud resources to scale gracefully in the presence of rapid increases in workload. We demonstrate the feasibility of the approach in an experimental evaluation with a testbed cloud and a realistic simulation of a large scale external XMPP chat service.We conclude that cloud computing with adaptive resource allocation has the potential to increase the usability, stability, and performance of large-scale back-end mashup applications.
Authenticated Tangible Interaction using RFID and Depth-Sensing Cameras - Supporting Collaboration on Interactive Tabletops (2012)

Abstract—Interactive large screen displays like tabletops or walls can enhance the interaction between humans and computers. A major topic is the collaboration between multiple simultaneous interacting people. However, most systems suffer from the problem that a distinction of different users is not possible. Hence, in this paper the authors present a work in progress approach of combining various existing technologies in order to enable personalized authenticated tangible interactions on a tabletop. Therefore, authentication using Radio-Frequency Identification in combination with depth-sensing cameras is used. We demonstrate the feasibility of the approach, the multiple advantages for interaction and give an outlook on further activities and lessons learned. Keywords-natural user interfaces; multitouch interaction; tangible interaction; interactive table; authentication I.
New Magnetic Filter for Chemical Industry (1993)

An economical, inexpensive and compact magnetic filter with pulse magnetization and demagnetization of the filtering matrix, consuming no electric power throughout the process was constructed and its effectiveness was tested with micron–sized magnetite and Raney nickel catalyst. Complete filtration of + 1 μm particles was achieved at rate ≤ 150 m/h. The proposed filter can be of use in chemical industry for the recovery of micron–sized magnetic particles from various liquors.
A novel compression tool for efficient storage of genome resequencing data (2011)

With the advent of DNA sequencing technologies, more and more reference genome sequences are available for many organisms. Analyzing sequence variation and understanding its biological importance are becoming a major research aim. However, how to store and process the huge amount of eukaryotic genome data, such as those of the human, mouse and rice, has become a challenge to biologists. Currently available bioinformatics tools used to compress genome sequence data have some limitations, such as the requirement of the reference single nucleotide polymorphisms (SNPs) map and information on deletions and insertions. Here, we present a novel compression tool for storing and analyzing Genome ReSequencing data, named GRS. GRS is able to process the genome sequence data without the use of the reference SNPs and other sequence variation information and automatically rebuild the individual genome sequence data using the reference genome sequence. When its performance was tested on the first Korean personal genome sequence data set, GRS was able to achieve ∼159-fold compression, reducing the size of the data from 2986.8 to 18.8 MB. While being tested against the sequencing data from rice and Arabidopsis thaliana, GRS compressed the 361.0 MB rice genome data to 4.4 MB, and the A. thaliana genome data from 115.1 MB to 6.5 KB. This de novo compression tool is available at http://gmdd.shgmo.org/Computational-Biology/GRS.
Self-Adjustment Time Quantum in Round Robin Algorithm Depending on Burst Time of the Now Running Processes (2009)

Problem statement: The performance and efficiency of multitasking operating systems mainly depends on the used CPU scheduling algorithm where the CPU is one of the primary computer resources and as round robin scheduling algorithm is considered most widely used scheduling algorithms in this research a new proposed variant of this algorithm presented, discussed in detail, tested and verified. Approach: The new proposed algorithm called Self-Adjustment-Round-Robin (SARR) based on a new approach called dynamic-time-quantum; the idea of this approach is to make the time quantum repeatedly adjusted according to the burst time of the now-running processes. Results: Based on the experiments and calculations that I have made the new modified algorithm radically solves the fixed time quantum problem which is considered a challenge for round robin algorithm. Conclusion: The use of dynamic scheduling algorithm increased the performance and stability of the operating system and support building of an self-adaptation operating system, which means that the system is who will adapt itself to the requirements of the user and not vice versa.
Does more data always yield better translations (2012)

Nowadays, there are large amounts of data available to train statistical machine translation systems. However, it is not clear whether all the training data actually help or not. A system trained on a subset of such huge bilingual corpora might outperform the use of all the bilingual data. This paper studies such issues by analysing two training data selection techniques: one based on approximating the probability of an indomain corpus; and another based on infrequent n-gram occurrence. Experimental results not only report significant improvements over random sentence selection but also an improvement over a system trained with the whole available data. Surprisingly, the improvements are obtained with just a small fraction of the data that accounts for less than 0.5 % of the sentences. Afterwards, we show that a much larger room for improvement exists, although this is done under non-realistic conditions. 1
Brain Metastases from Ovarian Carcinoma (2011)

This paper will focus on knowledge related to brain metastases from ovarian carcinoma. So far, less than 600 cases were documented in the literature with an incidence among ovarian carcinoma patients ranging from 0.29% to 11.6%. The ovarian carcinoma was usually an advanced-stage epithelial serous carcinoma, and the median interval between diagnosis of ovarian carcinoma and brain metastases was 2 years. Most often, brain metastases, affected the cerebrum, were multiple and part of a disseminated disease. Treatment of brain metastasis has evolved over the years from whole brain radiotherapy (WBRT) only to multimodal therapy including surgical resection or stereotactic radiosurgery followed by WBRT and/or chemotherapy. The median survival after diagnosis of brain metastases was 6 months; nevertheless, a significantly better survival was achieved with multimodal therapy compared to WBRT only. It is suggested that brain imaging studies should be included in the followup of patients after treatment for ovarian carcinoma.
Electrochemical kinetics of sei growth on Carbon Black: Part I. experiments (2019)

Growth of the solid electrolyte interphase (SEI) is a primary driver of capacity fade in lithium-ion batteries. Despite its importance to this device and intense research interest, the fundamental mechanisms underpinning SEI growth remain unclear. In Part I of this work, we present an electroanalytical method to measure the dependence of SEI growth on potential, current magnitude, and current direction during galvanostatic cycling of carbon black/Li half cells.We find that SEI growth strongly depends on all three parameters; most notably, we find SEI growth rates increase with nominal C rate and are significantly higher on lithiation than on delithiation. We observe this directional effect in both galvanostatic and potentiostatic experiments and discuss hypotheses that could explain this observation. This work identifies a strong coupling between SEI growth and charge storage (e.g., intercalation and capacitance) in carbon negative electrodes.
Bridgehead Lithiation-Substitution of Bridged Ketones, Lactones, Lactams, and Imides: Experimental Observations and Computational Insights (2009)

The viability of bridgehead lithiation-substitution of bridged carbonyl compounds has been tested in the laboratory, and the results were rationalized with the aid of a computational study. Lithiation-substitution was found to be possible for ketones, lactones, lactams, and imides having small bridges, including examples having [3.2.1], [3.2.2], [3.3.1], [4.2.1], and [4.3.1] skeletons. Smaller systems, where the sum of the bridging atoms (S) was 5, for example [2.2.1] or [3.1.1] ketones or [2.2.1] lactams, did not undergo controlled bridgehead substitution. Ketones or lactams having a [2.2.2] structure also did not give bridgehead substitution. B3LYP calculations accurately predict this behavior with negative DeltaE(rxn) values being calculated for the successful deprotonations and positive DeltaE(rxn) values being calculated for the unsuccessful ones. NBO calculations were also performed on the anionic deprotonated species, and these show that some structures are best represented as bridgehead enolates and some are best represented as alpha-keto carbanions.
The metabolism of aromatic compounds by <i>Rhodopseudomonas palustris</i>. A new, reductive, method of aromatic ring metabolism (1969)

1. Rhodopseudomonas palustris grows both aerobically and photosynthetically on aromatic acids. p-Hydroxybenzoate and protocatechuate are able to support aerobic growth; these compounds are metabolized by the protocatechuate 4,5-oxygenase pathway. 2. The photoassimilation of benzoate and hydroxybenzoates and the effects of air and darkness on the photoassimilation of benzoate are described. 3. Evidence in conflict with the pathway previously proposed for the photometabolism of benzoate is discussed. 4. The photometabolism of benzoate is accomplished by a novel reductive pathway involving its reduction to cyclohex-1-ene-1-carboxylate, followed by hydration to 2-hydroxycyclohexanecarboxylate and after dehydrogenation to 2-oxocyclohexanecarboxylate further hydration results in ring-fission and the production of pimelate. 5. Attempts were made to prepare cell-free extracts capable of dissimilating benzoate.
Effects of base ingredient in cooked molasses blocks on intake and digestion of prairie hay by beef steers. (2000)

Twelve steers (332 kg) were used in three simultaneous 4 x 3 incomplete Latin squares to evaluate effects of beet molasses (BEET), cane molasses (CANE), or concentrated separator by-product (CSB) as base ingredients in cooked molasses blocks on intake and digestion of prairie hay and ruminal characteristics. All steers had ad libitum access to prairie hay (5.9% CP and 69.4% NDF; DM basis). The four experimental treatments included a control (no supplement) and three cooked molasses blocks, based on BEET, CANE, or CSB, fed daily at .125% of BW (.42 kg/d as-fed, .13 kg/d CP). Forage OM, NDF, and N intakes; digestible OM, NDF, and N intakes; and total tract OM and N digestibilities (percentage of intake) were greater (P < .05) for steers fed cooked molasses blocks than for control steers. Total tract OM digestibility was greater (P < or = .06) for steers fed BEET blocks (54.0%) than for those fed CSB (52.1%) or CANE blocks (52.2%). Digestion of NDF was greatest (P < .05) for steers fed BEET blocks (51.9%) and tended to be greater (P < .07) for steers fed CANE (49.3%) or CSB blocks (49.3%) than for control steers (46.9%). Ruminal ammonia concentrations were greater (P < .05) for steers fed cooked molasses blocks (.89 mM) than for control steers (.21 mM); this was primarily due to increases to 4.6 mM at 2 h postfeeding for steers fed blocks. Concentrations of total VFA in ruminal fluid were greater (P < .05) for steers fed BEET (92.7 mM) and CSB (88.1 mM) blocks than for control steers (80.3 mM), whereas concentrations for steers fed CANE blocks were intermediate (85.4 mM). Steers supplemented with cooked molasses blocks had greater molar percentages of butyrate than did control steers, particularly shortly after feeding. In summary, supplementation with cooked molasses blocks increased forage intake and digestion. The three base ingredients elicited similar responses, although steers fed BEET had slightly greater OM and NDF digestibilities than those fed CANE or CSB.
On optimizing energy consumption: An adaptative authentication level in wireless sensor networks (2011)

Nowadays's authentication methods are essentially based on cryptography or any other kind of secret information. These methods are particularly efficient but they are, in certain cases, very power-hungry. As energy is a scarce resource in wireless sensor networks, we propose a new approach that consists in utilising the physical properties of the transmission medium in order to calculate, when receiving a frame, a confidence rating that we attribute to the source of the frame. This information is important in order to decide if it is necessary to authenticate the source using asymmetric cryptography. In the case where sensors are static and communications are slightly perturbed by the environment, the proposed rating can add another layer of control which enables sensors to check the origin of messages. This paper will also study how collaboration between the network's nodes further enhances detection of malicious or third-party nodes.
ECG as a First Step in the Detection of Left Ventricular Systolic Dysfunction in the Elderly (2015)

Ninety percent of LVSD may be detected, and when there is atrial fibrillation, pacing or LBBB, or QRS ≥ 120 ms/Q-waves and NT-proBNP>35 pmol/L, a diagnostic echocardiography should be considered.

HLA-DR binding analysis of peptides from islet antigens in IDDM. (1998)

HLA molecules are essential for thymic education and HLA restriction of T-cell responses. We therefore analyzed the HLA-DR binding affinities of synthetic peptides covering the entire sequences of GAD65, islet cell antigen 69 (ICA69), and (pro)insulin, which are candidate antigens in the autoimmune process of T-cell-mediated destruction of the pancreatic beta-cells. Subsequently, peptide HLA-DR binding was correlated to peptide antigenicity by comparing known T-cell epitopes with their HLA-binding affinities defined in this study. The results demonstrate the following. 1) (Pro)insulin peptides display a strong binding affinity for HLA-DR2, which is associated with negative genetic predisposition to IDDM, whereas poor binding was observed for HLA-DR molecules neutrally or positively associated with IDDM. This suggests that the absence of insulin-reactive T-cells in DR2+ individuals may be explained by negative selection on high-affinity DR2 binding insulin peptides. 2) Most autoantigenic peptides display promiscuous HLA-DR binding patterns. This promiscuity in itself is not sufficient to explain the genetic association of HLA-DR with development of IDDM. 3) HLA-DR3 binding of autoantigenic GAD65 peptides is relatively weak compared with that of other known T-cell epitopes. 4) All peptide epitopes recognized by HLA-DR-restricted T-cells from either IDDM patients or GAD65-immunized HLA-DR transgenic mice bind with high affinity to their HLA-DR restriction molecule (P < 0.0006). In contrast, T-cell epitopes recognized by nondiabetic controls bind DR molecules with weak or undetectable affinity. These results thus indicate a strong correlation between antigenicity and HLA-DR binding affinity of GAD65 peptides in IDDM. Furthermore, negative thymic selection of insulin peptides in low-risk (HLA-DR2 expressing) subjects may explain the lack of autoreactivity to insulin in such individuals.
Photoemission studies of the interaction of Li and solid molecular oxygen (1989)

The interaction of Li and oxygen has been studied at 25 K. This system serves as an excellent prototype for studying the interaction of alkali metals with oxygen. For some of the alkali metals, such as Cs or K, oxygen can be incorporated below the metal surface and complex valence-band and core-level features are obtained. In the case of Li at 25 K this does not appear to happen, and the core-level and valence-band features can be identified with the formation of the superoxide, the peroxide, and the oxide.
Rank Ordering Criteria Weighting Methods – a Comparative Overview (2013)

Multicriteria decision making (MCDM) refers to screening, prioritizing, ranking or selecting the alternatives based on human judgment from among a finite set of ` alternatives in terms of the multiple usually conflicting criteria. A very significant role in MCDM models plays the weights of criteria which usually provide the information about the relative importance of the considered criteria. Several different methods are developed to take criteria priorities into account.
