Facile synthesis, optical properties and growth mechanism of elongated Mn-doped ZnSe1−xSx nanocrystals (2012)

Transition-metal doping in semiconductors is an important way to modulate their intrinsic properties or bring out new functionalities for applications. Here, elongated Mn-doped ZnSe1−xSx nanocrystals are synthesized through a facile one-pot reaction under mild conditions. These ZnSe1−xSx nanocrystals with a diameter of 2–4 nm have a cubic phase structure. EPR and PL spectra confirm the successful doping of Mn2+ into the ZnSe1−xSx nanocrystals, based on the corresponding hyperfine splitting constants and emission bands. The temporal evolution of UV-vis absorption and PL spectra indicates the growth-doping mechanism for the formation of the doped nanocrystals. Surface coating of these nanocrystals with a shell increases the quantum yield up to 35%. And the dual-function role of 1-dodecanethiol is confirmed in the formation of the elongated Mn-doped ZnSe1−xSx nanocrystals.
The study on the active zinc powder used for aircraft zinc/silver secondary batteries (2004)

In this paper, the fabrication technique for making an active zinc powder was described and the performance of the active zinc powder electrode used for zinc/silver secondary batteries was studied. An active zinc powder with a high purity(more than 95%),high specific surface area( 0.173m~2/g );and can discharge at more than 7C was synthesed by electrodeposition method. And then an active zinc powder electrode were made to directly by pressing or filling the powder on the current collection. The battery's capacity loss can be less than 1% per year by treating with the special corrosion resistance. The results show that the performance of the active zinc powder electrode used for Zinc/Silver second batteries was similar to the formation zinc electrode.
A Multi-Time-Scale Flamelet Progress Variable Approach in OpenNCC for Predicting NOx Applied to Commercial Supersonic Transport Combustor Designs (2020)

This paper presents the implementation of a Multi-Time Scale Flamelet/Progress Variable (MTS-FPV) approach into OpenNCC for performing NOx prediction studies of Commercial Supersonic Transport (CST) gas turbine combustor design concepts. With the MTS-FPV approach, the primary flame and the NOx production are decoupled due to the disparate time scales associated with each process. A multiphase flamelet progress variable approach that has been developed and validated in our prior work is employed for the primary flame and the NOx species are transported independently as separate scalars. Detailed NOx chemistry is employed through the use of a dedicated chemistry manager. Such a framework is shown to accurately capture the NOx emission evolution in a cost-effective manner. The MTS-FPV approach is expected to provide ~10X speedup for large kinetic models and enable trade studies using higher fidelity computational design support tools, including the assessment of alternative fuels as a means to reduce emissions. To demonstrate the implementation of the multiphase extension of the MTS-FPV, results are presented for a steady Reynolds Averaged Navier Stokes (RANS) of a Lean Direct Engine (LDI) model combustor using conventional aviation jet fuel (A2) as the baseline fuel. The primary flame and NOx predictions are compared between a spray injection and a gas-phase injection of the fuel. Some differences are observed in the flame and species distribution which are discussed. Finally, to showcase the capability of the MTS-FPV approach to perform design trade studies, the sensitivity of the NOx predictions to two different fuels (C1 and RP2) are evaluated relative to the baseline fuel. The predicted EINOX (the NOx emission index) levels were found compare reasonably well with experimental values (extrapolated to the current condition).
Desorption sonic spray ionization for (high) voltage‐free ambient mass spectrometry (2006)

Sonic spray ionization is shown to create a supersonic cloud of charged droplets able to promote efficient desorption and ionization of drugs directly from the surfaces of commercial drug tablets at ambient conditions. Compared with desorption electrospray ionization (DESI), desorption sonic spray ionization (DeSSI) is advantageous since it uses neither heating nor high voltages at the spray capillary. DeSSI therefore provides a more friendly environment in which to perform ambient mass spectrometry (MS). DeSSI-MS is herein evaluated for the analysis of drug tablets, and found to be, in general, as sensitive as DESI-MS. The (high) voltage-free DeSSI method provides, however, cleaner mass spectra with less abundant solvent cluster ions and with enough abundant analyte signal for tandem mass spectrometry (MS/MS). These features may therefore facilitate the DeSSI-MS detection of low molar mass components or impurities, or both. The higher-velocity supersonic DeSSI spray also facilitates matrix penetration thus providing more homogenous sampling and longer lasting ion signals.
Inhibition of Cell Proliferation in Renal Failure and its Significance to the Uraemic Syndrome: A Review (1975)

The effect of acute and chronic renal failure on cell proliferation in rapidly dividing tissues has been examined in man and animal models. The evidence reviewed supports the hypothesis that renal failure results in a general inhibition of cell proliferation. Cell population kinetic studies of gastrointestinal and skin epithelia in experimental acute renal failure show a prolongation of the cell generation cycle. Less detailed investigations of other proliferative cell systems indicate an inhibitory effect on proliferation within the generative compartment of the erythroid series, lymphoid tissue, seminiferous epithelia and wound granulation tissue. This inhibition appears partly responsible for anaemia and impaired wound healing and may contribute to the abnormal immune responses, gastrointestinal tract lesions and male sterility found in renal failure.
S-Aframe: Agent-Based Multilayer Framework With Context-Aware Semantic Service for Vehicular Social Networks (2015)

This paper presents S-Aframe, an agent-based multilayer framework with context-aware semantic service (CSS) to support the development and deployment of context-aware applications for vehicular social networks (VSNs) formed by in-vehicle or mobile devices used by drivers, passengers, and pedestrians. The programming model of the framework incorporates features that support collaborations between mobile agents to provide communication services on behalf of owner applications, and service (or resident) agents to provide application services on mobile devices. Using this model, different self-adaptive applications and services for VSNs can be effectively developed and deployed. Built on top of the mobile devices' operating systems, the framework architecture consists of framework service layer, software agent layer and owner application layer. Integrated with the proposed novel CSS, applications developed on the framework can autonomously and intelligently self-adapt to rapidly changing network connectivity and dynamic contexts of VSN users. A practical implementation and experimental evaluations of S-Aframe are presented to demonstrate its reliability and efficiency in terms of computation and communication performance on popular mobile devices. In addition, a VSN-based smart ride application is developed to demonstrate the functionality and practical usefulness of S-Aframe.
A review of associative classification mining (2007)

Abstract Associative classification mining is a promising approach in data mining that utilizes the association rule discovery techniques to construct classification systems, also known as associative classifiers. In the last few years, a number of associative classification algorithms have been proposed, i.e. CPAR, CMAR, MCAR, MMAC and others. These algorithms employ several different rule discovery, rule ranking, rule pruning, rule prediction and rule evaluation methods. This paper focuses on surveying and comparing the state-of-the-art associative classification techniques with regards to the above criteria. Finally, future directions in associative classification, such as incremental learning and mining low-quality data sets, are also highlighted in this paper.
The Impact of Costimulatory Molecule Gene Polymorphisms on Clinical Outcomes in Liver Transplantation (2003)

CTLA-4 and CD28 deliver opposing signals for T-cell proliferation. We examined single nucleotide polymorphisms (SNPs) CTLA-4 -318C/T and CD28 IVS3 +17T/C for associations with acute rejection in liver transplant recipients. These and two other polymorphisms in CTLA-4 [microsatellite polymorphism +642(AT)n and SNP +49 A/G] were also analyzed for influence on graft survival. Two hundred and eleven liver transplant recipient genotypes were determined by direct sequencing or restriction fragment length polymorphism analysis of PCR-amplified genomic DNA. Mean graft survival for patients with the GG genotype of CTLA-4 +49 A/G was 58.5 +/- 6.0 months compared with 70.3 +/- 4.0 months and 73.8 +/- 2.8 months for the AA and AG genotypes, respectively (p = 0.0055). This is in support of previous studies suggesting decreased CTLA-4 function and increased incidence of autoimmune disease for this genotype. The 92-, 94-, and 100-bp alleles of CTLA-4 +642(AT)n occurred more often in African-American transplant recipients and were associated with decreased graft survival (p = 0.0001 and 0.007, respectively) but the independence of these variables could not be established. No associations with acute rejection or graft survival were found for CTLA-4 -318C/T or CD28 IVS3 +17T/C. The described associations between CTLA-4 gene polymorphisms and transplant outcomes provide the foundation for further investigations leading to genetic risk stratification for transplant recipients.

The investigation of radiopharmaceutical components by fast atom bombardment mass spectrometry: the identification of Tc-HIDA and the epimers of Tc-CO2DADS. (1983)

The nature of two technetium-labeled radiopharmaceutical components has been established by means of fast-atom-bombardment mass spectrometry (FABMS) in combination with carrier-added (CA) and no-carrier-added (NCA) reversed-phase high-pressure liquid chromatography (HPLC). Negative-ion FABMS was used to determine that the epimers of Tc-CO2DADS are the oxo[N,N'-(1-carboxyethylene)-bis-(2-mercaptoacetimido)]technetate(V) ions; positive-ion FABMS showed that Tc-HIDA is bis[N-(2,6-dimethylphenyl-carbamoylmethyliminodiaceto]technetate(III).
Synthesis of 3-Cyano-6-hydroxy-5-[2-(perfluoroalkyl)phenylazo]-2-pyridones and Their Application for Dye Diffusion Thermal Transfer Printing (1993)

Abstract New fluorine-containing azopyridone dyes, 3-cyano-6-hydroxy-5-[2-(perfluoroalkyl)phenylazo]-2-pyridones, have been synthesized. Though the introduction of a long perfluoroalkyl group lowered film forming ability and sensitivity, 5-[2-(trifluoromethyl)phenylazo]- and 5-[2-(perfluorobutyl)phenylazo]-3-cyano-4-methyl-6-hydroxy-2-pyridones showed good photostability.
Interactive Mobile Health Monitoring System (2017)

Health monitoring system is an active application in pervasive and ubiquitous computing. It is an application of mobile computing technology for enhancing communication among health care workers, physicians and patients with a view to provide better health care system. Recent elevation in sensors, wireless communication and low-power integrated circuits has empowered the design of pocket size, light weight, low-cost, and interactive bio-sensor nodes. These nodes are seamlessly integrated for mobile health monitoring using wireless body area network which can sense, process and communicate one or more vital parameters. The proposed system, through mobile device can provide patient health parameters (such as temperature, heart rate and ECG) to medical server, care taker and to medical practitioner based on the biomedical and environmental data collected by deployed sensors. In this system, multiple physiological parameters are incorporated for monitoring as against one or two parameters in legacy system. In this paper hardware, software and implementation of system is discussed whereas the focus is on authentication, power consumption, accuracy in transmission of health parameters to medical server.
Self‐Relay Gold(I)‐Catalyzed Pictet–Spengler/Cyclization Cascade Reaction for the Rapid Elaboration of Pentacyclic Indole Derivatives (2015)

Gold-catalyzed cascade reactions allow the rapid elaboration of pentacyclic indolo[2,3-a]quinolizidines from N-allyl tryptamines and ortho-alkynylarylaldehydes. The tandem process combines a gold-catalyzed Pictet-Spengler reaction and a cyclization occurring concomitantly with an allyl transfer from the nitrogen atom to the stilbene function. Various substituted allyls were successfully transferred, furnishing the products in yields typically ranging from 60-98 % in high diastereoselectivity. Tryptamines bearing a butenol chain undergo an additional cyclization to chiral hemiaminals in high diastereoselectivities.
Characterization and distribution of nucleic acid sequences of a novel type C retrovirus isolated from neoplastic human T lymphocytes. (1981)

A type C retrovirus (designated HTLV) recently isolated from a cell line derived from a lymph node and later from peripheral blood of a person with cutaneous T-cell lymphoma (mycosis fungoides) was characterized by nucleic acid hybridization experiments. HTLV [3H]cDNA hybridized 90% to its own 70S RNA with kinetics consistent with the genetic complexity of other retroviruses, but it did not hybridize substantially to RNA or proviral DNA from any animal retroviruses (types B, C, and D), including those from nonhuman primates. Conversely, [3H]cDNA from other retroviruses did not hybridize to RNA or DNA of the human T-cell line producing HTLV. HTLV proviral sequences were present (two to three copies per haploid genome) in DNA of these cells, and homologous sequences were present in the cell cytoplasmic RNA (0.3% viral sequences by weight). HTLV-related nucleic acid sequences were not found in DNA from various other human tissues. The results indicate that HTLV is a new class of type C virus that is not an endogenous (genetically transmitted) retrovirus in man.
Li / β ‐  VOPO 4: A New 4 V System for Lithium Batteries (1999)

Lithium intercalation into has been performed, both chemically and electrochemically, with X‐ray diffraction characterization of the resulting phases at various levels of intercalation‐deintercalation. It is shown that intercalation occurs through a first‐order transition at 3.98 V vs. , which leads to a ‐like structure but with lithium ordering which doubles the a and b unit cell parameters. Starting from chemically intercalated , the reversible process involves 0.55 electron per transition metal, i.e., 90 mAh/g, at a C/50 rate which owing to the 3.95 V potential plateau, gives an attractive specific energy of 355 Wh/kg. Fundamentally, it is shown herein that the redox energy of couple in an octahedral coordination involving unit is included between those observed in oxides and in compounds with oxo‐anions. © 1999 The Electrochemical Society.

Who needs addresses? (2002)

The author describes a framework for virtualising network addresses, reasoning that virtualisation requires reversing the usual the network-first, resource-second addressing order. A hierarchical name space is constructed for representing the shared resources by a homogenised form of URLs, a logical end-to-end route is constructed by combining the bind and connect requests over this name space, and used instead of end-to-end addresses for setting up virtual paths. Direct interpretation of the homogenised URLs ensures logical routing performance comparable to IP routing, and the logical route provides geographical trimming of the search in the transaction to virtual paths. Resulting features include a simple, uniform API for both point-to-point and multipoint connectivity, host security by invisibility, etc., which can be availed by privately deploying the framework over the existing networks.
Dosage and Administration Issues of Antipsychotic Agents (and Adjunctive Medicines) in the Acute Stabilization of Psychoses (2004)

There are several options and approaches available to practicing psychiatrists for the pharmacologic management of acute psychotic episodes that present in emergency room settings. This article focuses on the first hours and days of such episodes, the goals of treatment, and comparison of the "old favorites," such as combination haloperidol and lorazepam (in liquid, tablet or injectable formulations), with the newer second-generation antipsychotic agents, such as olanzapine, ziprasidone, risperidone, quetiapine, or aripiprazole, which are available in different formulations. The speed of titration to an effective target dose for these newer agents are addressed as well.
Designing a moderately spread mode for VLF communications (2002)

The design tradeoffs involved in implementing these VLF communication modes, the basic mode parameters, and the synchronization and framing of the system are discussed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
A Mouse Fas-Associated Protein with Homology to the Human Mort1/FADD Protein Is Essential for Fas-Induced Apoptosis (1996)

The Fas cell surface receptor belongs to the tumor necrosis factor receptor family and can initiate apoptosis in a variety of cell types. Using the Fas cytoplasmic domain as bait in a yeast two-hybrid screening, we isolated a mouse cDNA encoding a 205-amino-acid protein. Its predicted protein sequence shows 68% identity and 80% similarity with the sequence of recently described human Mort/FADD. This protein, most likely the mouse homolog of human FADD, associates with Fas in vivo only upon the induction of cell death. A fraction of this protein is highly phosphorylated at serine/threonine residues, with both phosphorylated and unphosphorylated forms being capable of binding to FAS. Stable expression of a truncated form of the Mort/FADD protein protects cells from Fas-mediated apoptosis by interfering with the wild-type protein-Fas interaction. Thus, mouse Mort/FADD is an essential downstream component that mediates Fas-induced apoptosis.
An Efficient Network Log Anomaly Detection System Using Random Projection Dimensionality Reduction (2014)

Network traffic is increasing all the time and network services are becoming more complex and vulnerable. To protect these networks, intrusion detection systems are used. Signature-based intrusion detection cannot find previously unknown attacks, which is why anomaly detection is needed. However, many new systems are slow and complicated. We propose a log anomaly detection framework which aims to facilitate quick anomaly detection and also provide visualizations of the network traffic structure. The system preprocesses network logs into a numerical data matrix, reduces the dimensionality of this matrix using random projection and uses Mahalanobis distance to find outliers and calculate an anomaly score for each data point. Log lines that are too different are flagged as anomalies. The system is tested with real-world network data, and actual intrusion attempts are found. In addition, visualizations are created to represent the structure of the network data. We also perform computational time evaluation to ensure the performance is feasible. The system is fast, finds intrusion attempts and does not need clean training data.
Histologic Subtypes of Ovarian Carcinoma (2008)

Reproducible subclassification of ovarian carcinomas is biologically and increasingly therapeutically important. The traditional morphologic approach that ignores genotype and immunophenotype is subjective and therefore suboptimal. This review covers the prevalence, morphology, immunophenotype and, in some cases, genotype of each major ovarian cancer subtype. Serous carcinomas, frequently WT1 positive, are morphologically diverse and mimic other tumors. Most transitional cell carcinomas are closely related to them. Mucinous carcinomas are uncommon and should only be diagnosed after extraovarian primaries are excluded; true ovarian mucinous carcinomas are usually low stage. Intestinal and mullerian mucinous (seromucinous) tumors are histogenetically and clinically distinct. Ovarian endometrioid carcinomas almost always resemble endometrioid carcinomas of endometrium, express estrogen receptors (ER) but not WT1, and are frequently low grade and low stage. Ovarian clear cell carcinomas, negative for ER and WT1 and lacking p53 overexpression, have a limited morphologic repertoire and are frequently low stage at presentation. Clinical biology, immunohistochemistry, and genotype can be used to enhance diagnostic objectivity.
Robust autofocusing in microscopy (2000)

The proposed method is generally applicable in light microscopy, whenever the image information content is sufficient. The reliability of the autofocus method allows for unattended operation on a large scale.
