Transformation of N-(5-Acetyl-6-methyl-2-oxo-2H-pyran-3-yl)benzamide with Hydrazines in the Presence of an Acidic Catalyst (2003)

2H-Pyran-2-one derivative (1) was transformed with heterocyclic hydrazines and 2,4-dinitrophenylhydrazine, under the influence of various acidic catalysts, into N- [5-(1-hydrazonoethyl)-6-methyl-2-oxo-2H-pyran-3-yl]benzamides (3) as the main products, accompanied in some cases by the corresponding (E)-α,β-didehydro-α-amino acid derivatives (4).2H-Pyran-2-ones and fused pyran-2-ones are important biologically active compounds and synthetic intermediates. 1 They react with nitrogen-containing nucleophiles either at a side chain or by an opening of the pyran-2-one ring and a subsequent ring closure to give various pyridin-2(1H)-ones, pyrazoles or other rings.1b,c,2 Recently, we described a transformation of N-(5-acetyl-6-methyl-2-oxo-2H-pyran-3-yl)benzamide (1) with various hydrazines into the pyrazoles containing α,β-didehydro-α-amino acid moiety. 3e reaction took place either as a two-step process via the corresponding hydrazone derivative, which was obtained under acidic conditions and further transformed under aqueous basic conditions, 3a or as a one-pot process under different basic conditions.3b More complex reaction was observed in the case of related N- (5-benzoyl-6-methyl-2-oxo-2H-pyran-3-yl)benzamide, whose reaction with various hydrazines or hydroxylamine in the appropriate solvent (predominantly a mixture of ethanol and pyridine) gave α,β-didehydroamino acid derivatives containing either a pyrazolyl or an isoxazolyl residue at the β-position.3b,4 With phenylhydrazines possessing electron-withdrawing or sterically bulky groups, as well as with heterocyclic hydrazines, complex (E/Z)-mixtures of α,β-didehydroamino acid derivatives and their decarboxylated analogs were usually obtained.In the related 2H-1-benzopyran-2-one series, benzopyran-2,5-diones were selectively converted into # This paper is a small contribution on the occasion of the 30 th anniversary of HETEROCYCLES.
Triglycerides and blood pressure in relation to circulating CD34-positive cell levels among community-dwelling elderly Japanese men: a cross-sectional study (2017)

A significant positive association between triglycerides and blood pressure exists among those with lower, but not higher, circulating CD34-positive cells. The level of circulating CD34-positive cells acts as a determinant factor for the association between triglycerides and blood pressure.
Securing traffic at QoS-aware residential gateway using biometric signatures (2008)

Home networks are becoming ubiquitous. Multimedia is a primary home network application that is challenging bandwidth capabilities with respect to QoS and also creating issues regarding authorized access to the home network and its digital content. To deal with these issues, this study presents an embedded QoS-aware residential gateway (EmQRG) in the home network which classifies forwarded traffic for optimal use of bounded network bandwidth resources and, instead of traditional password methodology, requires bimodal biometric recognition of users. A laboratory EmQRG testbed with bimodal biometric recognition system (BBRS) is implemented via class-based queuing (CBQ) bandwidth management in a 3-PC network including a real DiffServ-capable CBQ-capable router, CCD camera and optical fingerprint reader. Novel computational methods are used for face and fingerprint analysis and recognition. It is confirmed that combining two biometric modalities improves performance, particularly for the false acceptance rate (FAR) that is considered the most serious home security problem. Experimental results demonstrate efficiency and robustness of both the EmQRG and the BBRS.
A Survey of Wireless Technology for the Oil and Gas Industry (2008)

Summary The Institute of Electrical and Electronics Engineers (IEEE) 802.11/a/b/g specifications for wireless local-area networks (WLANs), the IEEE 802.15.4 specification for low-rate wireless personal-area networks, and the radio-frequency-identification (RFID) specifications have enabled a wide range of wireless applications such as wireless networking, sensing, monitoring and control, and asset and personnel tracking. For the oil and gas industry, using this technology will lead to reduced operating costs and will enable new applications. This paper identifies the technical requirements for wireless technology within the boundaries of the oil and gas industry. Experiments have been performed on wireless solutions within three application areas to examine whether or not currently available technologies fulfill these requirements. The conclusion is that WLAN technology is ready for deployment in oil and gas installations, while there remains a need for an open industrial standard for wireless-sensor networks (WSNs). Regarding RFID, our experiments show that solutions with passive tags are not suitable for asset- and personnel-tracking applications.
STRIDE--An integrated standards-based translational research informatics platform. (2009)

STRIDE (Stanford Translational Research Integrated Database Environment) is a research and development project at Stanford University to create a standards-based informatics platform supporting clinical and translational research. STRIDE consists of three integrated components: a clinical data warehouse, based on the HL7 Reference Information Model (RIM), containing clinical information on over 1.3 million pediatric and adult patients cared for at Stanford University Medical Center since 1995; an application development framework for building research data management applications on the STRIDE platform and a biospecimen data management system. STRIDE's semantic model uses standardized terminologies, such as SNOMED, RxNorm, ICD and CPT, to represent important biomedical concepts and their relationships. The system is in daily use at Stanford and is an important component of Stanford University's CTSA (Clinical and Translational Science Award) Informatics Program.
Fever of Uncertain Origin in Patients Infected with the Human Immunodeficiency Virus (1995)

To assess the frequency and etiology of fever of uncertain origin (FUO) in patients infected with the human immunodeficiency virus (HIV) and to evaluate the yield of diagnostic procedures used in their evaluation, we reviewed the clinical charts of all patients admitted to an AIDS unit during a 15-month period. FUO was defined by the endurance of a fever (temperature, > 38.2 degrees C) for at least 4 weeks before admission and the uncertainty of diagnosis after 3 days, despite appropriate investigation. Of 580 patients evaluated, 50 (8.2%) had FUO. Patients with FUO were at advanced stages of HIV infection (median CD4+ cell count, 71/mm3), and a vast majority (84%) had previously diagnosed AIDS. A cause of the fever was identified for 44 patients (88%), and infections accounted for 82% of all cases. Tuberculosis (42%), visceral leishmaniasis (14%), and disseminated Mycobacterium avium complex infection (14%) were the most frequent diagnoses. Examination of lymph node aspirates, bone marrow biopsy, and culture of clinical specimens for mycobacteria were the procedures with the highest diagnostic yield. Among 6 patients with fever of no identified etiology, 4 died while febrile, and fever was self-limited in the other 2 patients. FUO is common among patients with advanced HIV infection. Since a cause, usually infection, can be identified in most patients, long-lasting fever should not be attributed to HIV itself.
The R-type lipopolysaccharides of <i>Neisseria meningitidis</i> (1980)

The lipopolysaccharides of all the different serogroups of Neisseria meningitidis are of the "R" type despite the morphologically smooth appearance and the demonstrated virulence of the organisms from which they were derived. This was confirmed when each of the lipopolysaccharides was found to be devoid of detectable O-antigen side chains, giving only a low "molecular" weight core oligosaccharide when subjected to mild acid hydrolysis. The cores were modified by dephosphorylation and subjected to sugar and methylation analysis by gas-liquid chromatography. Although all the different cores contained identical components (glucose, galactose, glucosamine, heptose, and 2-keto-3-deoxyoctonate) they could be separated into three distinct categories according to their galactose:glucose ratios. These categories are typified by the cores obtained from groups A, C, and 29-e which have galactose:glucose ratios of 1:2, 2:2, and 2:1, respectively. The modified cores were methylated and analyzed by gas chromatography--mass spectrometry and on the basis of differences in the derived methylated sugars the cores could again be divided into the same three categories as above. This structural diversity also results in some serological specificity as demonstrated by the complete serogroup specificity of the group A lipopolysaccharide.
Inorganic Carbon Limitation Induces Transcripts Encoding Components of the CO2-Concentrating Mechanism in <i>Synechococcus</i> sp. PCC7942 through a Redox-Independent Pathway (2003)

The cyanobacterial CO2-concentrating mechanism (CCM) allows photosynthesis to proceed in CO2-limited aquatic environments, and its activity is modulated in response to inorganic carbon (Ci) availability. Real-time reverse transcriptase-PCR analysis was used to examine the transcriptional regulation of more than 30 CCM-related genes in Synechococcus sp. strain PCC7942 with an emphasis on genes encoding high-affinity Ci transporters and carboxysome-associated proteins. This approach was also used to test hypotheses about sensing of Ci limitation in cyanobacteria. The transcriptional response of Synechococcus sp. to severe Ci limitation occurs rapidly, being maximal within 30 to 60 min, and three distinct temporal responses were detected: (a). a rapid, transient induction for genes encoding carboxysome-associated proteins (ccmKLMNO, rbcLS, and icfA) and the transcriptional regulator, cmpR; (b). a slow sustained induction of psbAII; and (c). a rapid sustained induction of genes encoding the inducible Ci transporters cmpABCD, sbtA, and ndhF3-D3-chpY. The Ci-responsive transcripts investigated had half-lives of 15 min or less and were equally stable at high and low Ci. Through the use of a range of physiological conditions (light and Ci levels) and inhibitors such as 3-(3,4-dichlorophenyl)-1,1dimethylurea, glycolaldehyde, dithiothreitol, and ethoxyzolamide, we found that no strict correlation exists between expression of genes known to be induced under redox stress, such as psbAII, and the expression of the Ci-responsive CCM genes. We argue that redox stress, such as that which occurs under high-light stress, is unlikely to be a primary signal for sensing of Ci limitation in cyanobacteria. We discuss the data in relation to current theories of CO2 sensing in cyanobacteria.
Engineering Increased Stability in the Antimicrobial Peptide Pediocin PA-1 (2000)

Pediocin PA-1 is a food grade antimicrobial peptide that has been used as a food preservative. Upon storage at 4 degrees C or room temperature, pediocin PA-1 looses activity, and there is a concomitant 16-Da increase in the molecular mass. It is shown that the loss of activity follows first-order kinetics and that the instability can be prevented by replacing the single methionine residue (Met31) in pediocin PA-1. Replacing Met by Ala, Ile, or Leu protected the peptide from oxidation and had only minor effects on bacteriocin activity (for most indicator strains 100% activity was maintained). Replacement of Met by Asp was highly deleterious for bacteriocin activity.
RecDroid (2014)

The rapid growth of smartphone application market raises security concerns regarding untrusted applications. Studies have shown that most apps in markets request to collect data irrelevant to the main functions of the apps. Traditional permission control design based on one-time decisions on installation has been proven to be not effective to protect user privacy and poorly utilize scarce mobile resources (e.g. battery). In this work, we propose RecDroid, a framework for smartphone users to make permission control in real time and receive recommendations from expert users who use the same apps. This way users can benefit from the expert opinions and make correct permission granting decisions. We describe our vision on realizing our solution on Android and show that our solution is feasible, easy to use, and effective.
Multilabel Image Annotation Menggunakan Metode Convolutional Neural Network (2018)

Dengan berkembangnya sosial media terutama yang memiliki fitur untuk mengunggah foto dan gambar menyebabkan banyaknya gambar yang diunggah pada sosial media. Gambar tersebut dapat digunakan untuk membangun sistem pencarian gambar berbasis isi atau content-base image retrieval . Namun, banyak gambar yang diunggah tidak diberikan label atau tag sesuai dengan isi dari citra yang diunggah, sehingga sangat sulit untuk dikelola. Untuk dapat mewujudkan sistem pencarian gambar berbasis isi maka setiap obyek pada gambar harus dikenali terlebih dahulu. Jika pengenalan obyek tersebut dilakukan secara manual maka akan sangat sulit karena akan memakan waktu yang lama dan makna dari setiap orang terhadap suatu gambar berbeda, yang menimbulkan pengenalan obyek yang subyektif. Oleh karena itu dibangunlah sistem penganotasian gambar secara otomatis. Dalam penelitian ini diajukan sebuah metode Convolutional Neural Network untuk menangani sistem penganotasian gambar multilabel. metode Convolutional Neural Network telah terbukti memiliki performansi yang baik pada kasus klasifikasi gambar, ditunjukkan dengan performansi pada kasus klasifikasi gambar pada ILSVRC yang semakin membaik setiap tahunnya. Performansi tertinggi terhadap data uji pada penelitian ini adalah 81.24%.
Paraplegia after thoracic aortic occlusion: influence of cerebrospinal fluid drainage. Experimental and early clinical results. (1988)

Paraplegia occurs in 6.5% to 40% of patients after repair of extensive thoracoabdominal aortic aneurysms requiring aortic clamping. This study aimed to determine whether drainage of cerebrospinal fluid (CSF) done before aortic cross-clamping could decrease the incidence of paraplegia in dogs. The descending thoracic aorta was clamped distal to the left subclavian artery for either 40 minutes (group I) or 60 minutes (group II). All control animals in group I (10) and group II (10) showed evidence of spinal cord injury with paraparesis or paraplegia. In contrast, 9 of 10 animals (90%) in group I and 7 of 10 animals (70%) in group II that had CSF drainage before aortic cross-clamping were neurologically normal (p less than 0.001 and p less than 0.01, respectively). Aortic pressure distal to the aortic cross clamp was the same in all groups; however, spinal cord perfusion pressure (distal aortic pressure minus CSF pressure) was significantly higher in neurologically normal animals (34 +/- 5 mm Hg, n = 15) compared with those with paraparesis (26 +/- 4 mm Hg, n = 8) or paraplegia (19 +/- 5 mm Hg, n = 8) (r = 0.871, p less than 0.001). This study demonstrates that drainage of CSF before thoracic aortic occlusion significantly increases spinal cord perfusion pressure and decreases the incidence of paraplegia. Limited early clinical experience suggests that CSF drainage may be a useful adjunct to prevent paraplegia in patients who are having repair of thoracoabdominal aortic aneurysms.
Miscibility in binary blends of aromatic and alicyclic polyamides (2006)

Abstract Miscibility was studied for four polyamide blends of 6I/6T [copolymer consisting of 1,6‐hexamethylene diamine and isophthalic acid (6I) (70 wt %) and terephthalic acid (6T) (30 wt %)] with MXD6 (polyamide of m ‐xylenediamine and adipic acid), BAC6 (polyamide of 1,3‐bis(aminomethyl)cyclohexane and adipic acid), TR55 (copolymer consisting of nylon 11 (30 wt %), and polyamide of bis(3‐methyl, 4‐aminocyclohexyl)methane (30 wt %) and isophthalic acid (70 wt %), and CX7323 (polyamide of bis(4‐aminocyclohexyl)methane and dodecanedicarboxylic acid), using differential scanning calorimetry, X‐ray diffraction method, and electronmicroscopic observation. In quenched MXD6/(6I/6T) and BAC6/(6I/6T) blends, MXD6 and BAC6 components were miscible to 6I/6T, but TR55 and CX7323 components were completely phase‐separated from 6I/6T. Interestingly on electronmicroscopic observations, TR55 and CX7323 components were seen as droplets in 6I/6T medium when the content is low, but when 50 wt %, a layered structure was constructed with 6I/6T, reminiscent of morphological structure in block copolymer. © 2006 Wiley Periodicals, Inc.

Improved techniques for single-pass adaptive vector quantization (1994)

Constantinescu and Storer presented a new single-pass adaptive vector quantization algorithm that learns a codebook of variable size and shape entries; they presented experiments on a set of test images showing that with no training or prior knowledge of the data, for a given fidelity, the compression achieved typically equals or exceeds that of the JPEG standard. This paper presents improvements in speed (by employing K-D trees), simplicity of codebook entries, and visual quality with no loss in either the amount of compression or the SNR as compared to the original full-search version.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Antinuclear autoantibodies (ANA) in Gulf War-related illness and chronic fatigue syndrome (CFS) patients (2002)

It is established that veterans of the 1991 Gulf War have an increased frequency of experiencing multiple symptoms. The underlying mechanism of these ailments is unclear, although they do not correspond to any clearly defined syndrome. The most common symptoms overlap with those of chronic fatigue syndrome (CFS). CFS was recently associated with a novel subtype of antinuclear autoantibody (ANA) that reacts with nuclear envelope (NE) antigens. NE autoantibodies are not known to be linked with any distinct clinical condition, but have been observed in patients with unusual mixed chronic autoimmune disorders and connective tissue diseases. In this study we examined whether NE ANAs are a feature of patients with CFS and symptomatic Gulf War veterans (sGWV). We studied the prevalence of ANA in 130 sGWV, 90 well Gulf War veterans (wGWV), 128 symptomatic Bosnia and Era veterans (sBEV), 100 CFS patients, and 111 healthy control subjects matching for age and sex. We found no significant difference in the prevalence of ANAs between any of the groups. None of the patients/or veterans we studied had ANA of the NE type. Our results show that multisymptom illness due to CFS or related to Gulf War service is not associated with antinuclear autoimmunity.
A QoS-aware routing framework for PIM-SM based IP-multicast (2002)

We propose a PIM-SM based IP-multicast routing framework for delivering heterogeneous quality of service to multicast receivers. We propose two tree construction algorithms: TIQM (relying on the full availability of tree-specific information about a multicast group) and NUQM (not requiring any tree specific information). While TIQM is able to compute pseudo-optimal QoS-constrained trees, it has a control-scalability problem. This problem is overcome in NUQM by restricting the amount of information used during tree computation. For realistic networks, under low to moderate network load and receivers' bandwidth requirements, performance of NUQM is close to that of TIQM. A QoS-extended intra-domain PIM-SM framework is also presented.
A novel method of baseband pool resource allocation in Cloud Radio Access Network system (2015)

In order to improve the resource utilization and the operating revenue, also to reduce the power consumption and the total delay, the baseband pool resource management of CRAN (Cloud Radio Access Network) is studied in this paper. The baseband pool resources are divided into shared resources and fixed resources. Based on this classification, with the goal of maximizing the revenue, a novel resource allocation model is established, where the fixed resources are used preferentially when the available resource is sufficient to provide service to users, and when the system load is large, the shared resources will be utilized and the control center will allocate resources according to the priority of users and the current usage of the resources. Finally, the simulation results show the superiority of the proposed method.
Text-mined dataset of inorganic materials synthesis recipes (2019)

Materials discovery has become significantly facilitated and accelerated by high-throughput ab-initio computations. This ability to rapidly design interesting novel compounds has displaced the materials innovation bottleneck to the development of synthesis routes for the desired material. As there is no a fundamental theory for materials synthesis, one might attempt a data-driven approach for predicting inorganic materials synthesis, but this is impeded by the lack of a comprehensive database containing synthesis processes. To overcome this limitation, we have generated a dataset of "codified recipes" for solid-state synthesis automatically extracted from scientific publications. The dataset consists of 19,488 synthesis entries retrieved from 53,538 solid-state synthesis paragraphs by using text mining and natural language processing approaches. Every entry contains information about target material, starting compounds, operations used and their conditions, as well as the balanced chemical equation of the synthesis reaction. The dataset is publicly available and can be used for data mining of various aspects of inorganic materials synthesis.
Les crues de janvier-février 1995 dans le bassin de la Maine (FRANCE) (1999)

Dédiée aux sciences de l'atmosphère, au climat et à d'autres domaines connexes, tels que l'océanographie ou la glaciologie, La Météorologie, révisée par des pairs et publiée en français, s'adresse aux professionnels de la météo et du climat, aux enseignants, aux étudiants, aux amateurs et aux utilisateurs. La Météorologie a succédé en 1925 à l'Annuaire de la Société météorologique de France (1852-1924) qui avait lui-même succédé à l'Annuaire météorologique de la France (1849-1851).
