Second-Generation DBFOX Ligands for the Synthesis of β-Substituted α-Amino Acids via Enantioselective Radical Conjugate Additions (2008)

A set of second-generation DBFOX ligands possessing extended aryl or benzyl-type groups was synthesized. The requisite amino alcohols were either commercially available (DBFOX/Bn) or constructed via Sharpless asymmetric aminohydroxylation (DBFOX/Nap, DBFOX/ t-BuPh, DBFOX/Pip) or phase-transfer-catalyzed asymmetric alkylation (DBFOX/MeNap). Complexes of the ligands with Mg(NTf2)2 were evaluated as promoters of enantioselective radical conjugate additions to alpha,beta-unsaturated alpha-nitro amides and esters. Reactions employing the DBFOX/Nap ligand exhibited improved enantioselectivity relative to previously published additions mediated by DBFOX/Ph. However, the relatively modest increase in diastereomeric ratio suggests that our substrate-Lewis acid binding model, which was formulated based on results from DBFOX/Ph-promoted radical conjugate additions, is in need of revision.

Effectiveness of pneumococcal vaccines in preventing pneumonia in adults, a systematic review and meta-analyses of observational studies (2017)

Wide ranges in PPV23 effectiveness estimates for any-CAP were observed, likely due to a great diversity of study populations, circulation of S. pneumoniae serotypes, coverage of pediatric pneumococcal vaccination, case definition and time since vaccination. Despite some evidence for short-term protection, effectiveness of PPV23 against CAP was not consistent in the general population, the immunocompromised and subjects with underlying risk factors.
Étude cristallographique des orthoniobates et orthotantalates de lithium (1964)

NbLi₃O₄ et TaLi₃O₄ possèdent tous deux une forme basse température cubique de type NaCl. A plus haute température l'orthoniobate de lithium est cubique avec une maille a₀ = 8,429 Å correspondant à 2a NaCl. On a affaire à un ordre 1/3 niobium˗lithium. La structure de ce composé a été étudiée par diffraction de rayons X et de neutrons. La forme haute température de l'orthotantalate est quadratique centrée avec a₀ = 6,055 Å c₀ = 16,76 Å a₀ ~ √2 a NaCl c₀ ~ 4 a NaCl. Il s'agit encore d'un autre type d'ordre 1/3 des cations penta et monovalents. La détermination de la structure de ce dernier composé est en cours.
Interface modification for highly efficient organic photovoltaics (2008)

We present highly efficient inverted polymer:fullerene bulk-heterojunction solar cells by incorporation of a nanoscale organic interfacial layer between the indium tin oxide (ITO) and the metal oxide electron-conducting layer. We demonstrate that stacking of solution-processed organic and metal oxide interfacial layers gives highly charged selective low ohmic cathodes. The incorporation of a polyoxyethylene tridecyl ether interfacial layer between ITO and solution-processed titanium oxide (TiOx) raised the power conversion efficiency of inverted organic photovoltaics to 3.6%, an improvement of around 15% in their performance over comparable devices without the organic interfacial layer.
Manumycin inhibits ras signal transduction pathway and induces apoptosis in COLO320-DM human colon tumourcells (2000)

The aim of the present study was to assess the cytotoxicity of manumycin, a specific inhibitor of farnesyl:protein transferase, as well as its effects on protein isoprenylation and kinase-dependent signal transduction in COLO320-DM human colon adenocarcinoma which harbours a wild-type K-ras gene. Immunoblot analysis of isolated cell membranes and total cellular lysates of COLO320-DM cells demonstrated that manumycin dose-dependently reduced p21 ras farnesylation with a 50% inhibitory concentration (IC50) of 2.51 +/- 0.11 microM and 2.68 +/- 0.20 microM, respectively, while the geranylgeranylation of p21 rhoA and p21rap1 was not affected. Manumycin dose-dependently inhibited (IC50 = 2.40 +/- 0.67 microM) the phosphorylation of the mitogen-activated protein kinase/extracellular-regulated kinase 2 (p42MAPK/ERK2), the main cytoplasmic effector of p21ras, as well as COLO320-DM cell growth (IC50 = 3.58 +/- 0.27 microM) without affecting the biosynthesis of cholesterol. Mevalonic acid (MVA, 100 microM), a substrate of the isoprenoid synthesis, was unable to protect COLO320-DM cells from manumycin cytotoxicity. Finally, manumycin 1-25 microM for 24-72 h induced oligonucleosomal fragmentation in a dose- and time-dependent manner and MVA did not protect COLO320-DM cells from undergoing DNA cleavage. The present findings indicate that the inhibition of p21ras processing and signal transduction by manumycin is associated with marked inhibition of cell proliferation and apoptosis in colon cancer cells and the effect on cell growth does not require the presence of a mutated ras gene for maximal expression of chemotherapeutic activity.
Dependency Theory and the Study of Politics (1985)

Our chief concern in this chapter is with the third major critique of the political modernisation approach, that which arises out of dependency theory. We shall see that the primary focus of dependency theory is the international economic order. No society can be understood in isolation from this order and in fact the condition of underdevelopment is precisely the result of the incorporation of Third World economies into the world capitalist system which is dominated by the developed North. Accordingly the principal weakness of the modernisation approach from a dependency prespective is its total neglect of the economic dimension and its practice of explaining social and political change in the Third World entirely in terms of factors which are internal to the countries in question. In examining the impact of dependency theory on the study of politics we shall not be reviewing the wide range of dependency theories that have emerged during the last ten or fifteen years (see O'Brien, 1975, and Hoogvelt, 1982). We shall start by looking at the earlier writings of one of the most prominent dependency theorists, André Gunder Frank, their implications for the study of politics and certain critical reactions to these writings.
Protection of Mice Against the Vaccinia Virus by the Administration of Phenoxythiouracils (1951)

Summary Certain 5-phenoxythiouracils, although only moderately active inhibitors of vaccinia virus in chick embryonic tissue culture, have a significant protective effect in vivo. A reduction in the mortality of mice as a result of treatment could be demonstrated with the IHD strain inoculated intracerebrally and nasally and with the WR strain inoculated intracerebrally. The protective effect of therapy could be demonstrated only when treatment was begun soon after infection was initiated. Treated animals appeared to have a lower titer of virus in the brain than untreated animals. These facts suggest that these substances directly or indirectly diminish the rate of viral multiplication without, however, having a virucidal action. 5-(2′4′-Dichlorophenoxy)-4-hydroxy-2-mercaptopyrimidine was found to be the most effective compound tested. This substance protected mice against the vaccinia virus when administered parenterally or in the diet. It shows no demonstrable antibacterial activity at concentrations which inhibit growth of the vaccinia virus nor has a protective effect against other viruses been demonstrated.
Prediction of water vapor scale height from integrated water vapor measurements (2005)

A method for estimating the 10% height of water vapor in the atmosphere is presented. This 10% height is the altitude below which 10% of the atmospheric water vapor vertical distribution occurs. The estimation is based on a time series of ground-based measurements of integrated water vapor, and results from the behavior of the turbulence structure function for water vapor outside of the outer scale of tropospheric turbulence. This behavior is demonstrated by a model which expands on earlier work by Treuhaft and Lanyi on the behavior of atmospheric turbulence in a "frozen" atmosphere. The model integrates statistics of the climatological average water vapor profile with wind and integrated water vapor measurements. Microwave water vapor radiometer, radar wind profiler, and radiosonde data from the Continental Stratus campaign have been processed and the results are presented in support of the model. It is shown that, through the combination of integrated water vapor data from a microwave radiometer, wind profile data from a tropospheric radar, and a realistic model created with local radiosonde launches, the water vapor 10% height in the atmosphere can be successfully predicted with a simple algorithm.
[Diagnostic usefulness of transbronchial aspiration and bronchial lavage for pulmonary tuberculosis]. (1990)

Fiberoptic bronchoscopy is a well established methods as a useful tool in the diagnosis of pulmonary tuberculosis with smear negative cases. In order to get the early and definite diagnosis of pulmonary tuberculosis, we performed transbronchial aspiration and bronchial lavage by a fiberoptic bronchoscope in 97 patients. All patients (1) were clinically suspected of having active tuberculosis; (2) showed abnormal chest roentgenogram suggesting tuberculosis; (3) showed negative sputum smears of acid-fast bacilli, or had no sputum. The results of the study were summarized as follows: 1) Final diagnosis of study subjects were 90 patients of active pulmonary tuberculosis, and 7 patients of pulmonary atypical mycobacteriosis. 2) Sputum culture of acid-fast bacilli was positive in 22 out of 90 patients with active pulmonary tuberculosis. 3) Smear and culture examination of acid-fast bacilli of transbronchial aspirates were positive in 9 and 28, respectively out of 90 patients. 4) Smear and culture examination of acid-fast bacilli of bronchial lavage were positive in 12 and 39, respectively out of 90 patients. 5) A rapid and definite diagnosis was made in 16 out of 90 patients by transbronchial aspirates or bronchial lavage. 6) Atypical mycobacteria were detected in 7 out of 97 patients by transbronchial aspirates or bronchial lavage. 7) There were no serious complications such as pneumonia and exacerbation of pulmonary tuberculosis. These results suggested that transbronchial aspiration and bronchial lavage were useful procedures for rapid and definite diagnosis of pulmonary tuberculosis.
Sterischer Ablauf der Dehydratisierung von gasförmigem 2-Butanol-3-d<sub>1</sub> an AlPO<sub>4</sub>, Ba<sub>3</sub>(PO<sub>4</sub>)<sub>2</sub> und Ca<sub>3</sub>(PO<sub>4</sub>)<sub>2</sub> / Stereo Mechanism of Dehydration of Gaseous 2-Butanol-3-d<sub>1</sub> over AlPO<sub>4</sub>, Ba<sub>3</sub>(PO<sub>4</sub>)<sub>2</sub> and Ca<sub>3</sub>(PO<sub>4</sub>)<sub>2</sub> (1972)

Dehydration can proceed according to one (E2) or two (El, ElcB) step mechanisms. In the first case the leaving groups can be abstracted from the cis or trans (syn or anti) position. In order to get insight into the mechanism, the dehydration of 1-butanol, 2-butanol, D,L-erythro- and D,L-threo-2-butanol-3-d 1 as well as the isomerization of 1-butene and cis-2-butene were studied in the temperature range from 250 to 400°C, using microcatalytic and mass-spectrometric techniques. In order to distinguish between cis and trans elimination, erythro- and threo-2-butanol-3-d 1 were studied. Over AlPO 4 , Ba 3 (PO 4 ) 2 and Ca 3 (PO 4 ) 2 a simultaneous trans and cis mechanism was found. The ratio of cis to trans mechanism was calculated to be 85/15 with Ca 3 (PO 4 ) 2 , 70/30 with Ba 3 (PO 4 ) 2 and 45/55 with AlPO 4 . The cis mechanism is highest for Me-O-distances of the catalysts of 2.5 A which coincides practically with the distance between - OH and -H (D) to be eliminated
Crucial Role of Selenium in the Virucidal Activity of Benzisoselenazol-3(2H)-ones and Related Diselenides (2010)

Various N-substituted benzisoselenazol-3(2H)-ones and their non-selenium-containing analogues have been synthesized and tested against selected viruses (HHV-1, EMCV and VSV) to determine the extent to which selenium plays a role in antiviral activity. The data presented here show that the presence of selenium is crucial for the antiviral properties of benzisoselenazol-3(2H)-ones since their isostructural analogues having different groups but lacking selenium either did not show any antiviral activity or their activity was substantially lower. The open-chain analogues of benzisoselenazol-3(2H)-ones--diselenides also exhibited high antiviral activity while selenides and disulfides were completely inactive towards model viruses.
Transition Temperature of Strong-Coupled Superconductors (1968)

The superconducting transition temperature is calculated as a function of the electron-phonon and electron-electron coupling constants within the framework of the strong-coupling theory. Using this theoretical result, we find empirical values of the coupling constants and the "band-structure" density of states for a number of metals and alloys. It is noted that the electron-phonon coupling constant depends primarily on the phonon frequencies rather than on the electronic properties of the metal. Finally, using these results, one can predict a maximum superconducting transition temperature.
Matrix Metalloproteinases: A Therapeutic Target in Cardiovascular Disease (2003)

Cardiovascular disease is the leading cause of death in Western society. Extracellular matrix turnover is important in many cardiovascular pathologies, such as arterial remodeling, plaque rupture, restenosis, aneurysm formation and heart failure. Matrix metalloproteinases (MMPs) belong to a group of zinc and calcium dependent proteases and cause breakdown of the extracellular matrix. MMP inhibitors have been developed and tested for their effect on the outcome of oncological disease [1]. Recent preclinical research revealed that these MMP inhibitors could also have great potential in the field of cardiovascular disease. This preclinical research has encouraged investigators to design and start the first clinical studies with cardiovascular endpoints. In the present paper, the various aspects of MMP participation in cardiovascular disease will be summarized. Preclinical animal studies that demonstrated the effect and potential of applicable MMP inhibitors on different cardiovascular disease entities will be discussed. We will specifically focus on the role of MMPs and the potential of their inhibitors in de novo atherosclerotic plaque destabilization, arterial remodeling, restenosis after ballon angioplasty and stenting, aneurysm formation and heart failure. We conclude that MMP inhibitors are likely to be useful in the development of pharmacological approaches to reduce cardiovascular death, considering the positive outcomes after usage of MMP inhibitors in restenosis and arterial remodeling.
Activity-based user interface for network management (2003)

It is noted that network management systems can enhance the effectiveness of operators by providing goal-oriented user interfaces which support the way operators view their networks and their network operation activities. An object-oriented operations model which permits the explicit representation and manipulation of operator activities in the network management system software is presented. The benefits of the model include the selective grouping of tools relevant to operators' activities, the intelligent interworking and coordination of the tools within an activity, and the ability to manage an operation activity as a single entity. The model principles and the proposed activity-based user interface style are outlined, along with a prototype implementation and examples of the model's use for the management of packet switching networks.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Distributed Learning for Wireless Communications: Methods, Applications and Challenges (2022)

With its privacy-preserving and decentralized features, distributed learning plays an irreplaceable role in the era of wireless networks with a plethora of smart terminals, an explosion of information volume and increasingly sensitive data privacy issues. There is a tremendous increase in the number of scholars investigating how distributed learning can be employed to emerging wireless network paradigms in the physical layer, media access control layer and network layer. Nonetheless, research on distributed learning for wireless communications is still in its infancy. In this paper, we review the contemporary technical applications of distributed learning for wireless communications. We first introduce the typical frameworks and algorithms for distributed learning. Examples of applications of distributed learning frameworks in emerging wireless network paradigms are then provided. Finally, main research directions and challenges of distributed learning for wireless communications are discussed.
Symbolic evaluation of performance models for tradeoff visualization (1997)

Often during the design process, it is necessary to analyzethe effects of tradeoff among various performance attributesof the design.Visual representations in the formof plots, graphs, and tables are typically used.These visualizationscan be generated using different applications suchas MatLab®, Mathematica®, Excel®, and so forth.Inorder to use these tools, performance equations for the designmust be rendered in an equational form with only afew variables, usually 2-3.However, performance modelsusually consist of a large number of attributes and evaluzationprocedures, typically written using the full power of aprogramming or hardware description language.We introducea symbolic evaluation procedure to simplify performancemodels.Given partial data, such evaluation yields a residualperformance model which is simpler than the original model.Symbolic evaluation can be effectively used to obtain residualperformance equations in terms of the variables whosetradeoff visualization is of interest to the user.
Trust-Based Fast Inter-Domain Secure Handoff over Heterogeneous Wireless Networks (2011)

The emerging 3G-WLAN heterogeneous networks are attracting technologies for the next generation wireless communication system. A challenging issue for the technologies is how to reduce the secure handoff delay when users roam across multiple domains. Generally, the re-authentication procedure in a visited domain causes a large delay during a secure handoff that always involves communication with the home domain. Most existing solutions are based on pre-authentication between the different domains, which needs to statically build the roaming agreement between each pair of domains, and can not support dynamic and flexible co-operation for them. In this paper, we propose a fast authentication scheme, named as T-FISH, based on a trust-token mechanism to reduce the secure handoff delay. A trust-token is issued by the home domain or a visited domain, and uses attribute-based encryption (ABE) cryptography to encrypt key information. A mobile user with a trust-token can authenticate directly in a visited domain for fast handoff. The proposed scheme can realize a fine-grained access control and a scalable cooperation business model for wireless service providers (WSPs). To the best of our knowledge, this is the first secure handoff scheme based on the ABE cryptography. The analysis and evaluation show that the proposed scheme can effectively reduce the re-authentication delay without reducing the level of security, and it securely and dynamically extends the cooperation relationship between WSPs.

ANALYSIS OF THE HEMODYNAMIC CHARACTERISTICS OF BRAIN ARTERIOVENOUS MALFORMATIONS USING ELECTRICAL MODELS (2008)

These electrical models seem to be useful in simulating and studying the behavior of flow and pressure in the different parts of the AVM nidus (arterial, arteriolar, arteriolar-venular, venular, venous) before and after treatment. The models can also be used to devise and simulate new treatment strategies that might lead to improved treatment of these highly complex vascular malformations of the brain.
