Multipole sources in boreholes penetrating anisotropic formations: Numerical and experimental results (1992)

A 2.5-D velocity-stress finite-difference code is described that models acoustic propagation in a borehole penetrating a generally anisotropic formation. The excitation may be a dilatation (monopole), or a point force (dipole) in an arbitrary direction. The anisotropic formation is homogeneous along the axis of the borehole but may be inhomogeneous in the transverse plane. The borehole cross section and location of the source in the borehole are arbitrary. Synthetic time-domain waveforms are displayed for arrays of monopole and dipole receivers deployed along the borehole axis in both fast and slow anisotropic formations. The specific anisotropy model employed for the numerical results is a transversely isotropic (TI) formation with its axis of symmetry inclined with respect to the borehole axis by an arbitrary angle. Flexural/shear and Stoneley wave slowness and attenuation estimates are extracted from the synthetic waveforms using a variant of Prony’s method for a range of borehole inclinations relative to the formation axis of symmetry. In a fast formation, with borehole and formation symmetry axes perpendicular, flexural mode dispersion curves for quasi-SV and SH polarizations separate only at low frequency where moderate attenuation is also observed. In a slow formation, distinct dispersion curves are obtained for quasi-SV and SH polarizations over the entire frequency range. Moderate attenuation is again observed at low frequency. Scaled laboratory experiments confirm the numerical procedure. Experimental and numerical waveforms for monopole and several polarizations of dipole excitation in a transversely isotropic model formation overlay with excellent agreement.
Hirntod und intraokularer Druck (1988)

The article reports on the changing behaviour of the intraocular pressure of 20 patients who had a severe head injury. Eight patients survived; in this group intraocular pressure was always normal. Twelve patients developed brain death, and in contrast to the group of survivors all of them had intraocular hypotension. Papilloedema was never seen in funduscopic examinations; however, we found signs of fundus ischaemia in most patients who had died of brain death.
Design of A High Speed OFDM Modem For Power Line Communication (2007)

Broadband power line communication (PLC) is an excellent candidate for home network. OFDM is considered as the most appropriate modulation/demodulation schemes for high-speed data service by PLC. The design of a PLC modem based on the SPC-200E OFDM high-speed power line physical layer processor, including the design of physical layer and MAC layer, is proposed in this paper. And the performance of this modem in the PLC experiments over in-home low voltage power lines is given.

Recognition is the earliest step in any direct plant-microbe interaction. Recognition between Phytophthora pathogens, which are oomycetes, phylogenetically distinct from fungi, has been studied at two levels. Recognition of the host by the pathogen has focused on recognition of chemical, electrical, and physical features of plant roots by zoospores. Both host-specific factors such as isoflavones, and host-nonspecific factors such as amino acids, calcium, and electrical fields, influence zoospore taxis, encystment, cyst germination, and hyphal chemotropism in guiding the pathogen to potential infection sites. Recognition of the pathogen by the host defense machinery has been analyzed using biochemical and genetic approaches. Biochemical approaches have identified chemical elicitors of host defense responses, and in some cases, their cognate receptors from the host. Some elicitors, such as glucans and fatty acids, have broad host ranges, whereas others such as elicitins have narrow host ranges. Most elicitors identified appear to contribute primarily to basic or nonhost resistance. Genetic analysis has identified host resistance (R) genes and pathogen avirulence (Avr) genes that interact in a gene-for-gene manner. One Phytophthora Avr gene, Avr1b from P. sojae, has been cloned and characterized. It encodes a secreted elicitor that triggers a system-wide defense response in soybean plants carrying the cognate R gene, Rps1b.

The model predicts an exponential delta front profile, in which the maximum slope is controlled by the sediment supply to the delta, the rate of sediment transport on the delta front slope, and the depth of the receiving basin.Applications of the model to the Fraser and Mississippi River Deltas and to the Rhine River Delta in Lake Constance give good agreement with the progradation and morphology of these deltas. A difference in transport coefficient between the Mississippi River and the other deltas is attributed to differences in sediment composition and/or rate of sediment supply between this and the other deltas. The derived sediment-transport coefficients are found to be much higher than those for subaerial hillslopes. Our results suggest that deltas prograding by the processes considered in this paper will adjust quickly to changes in sediment supply. This content is PDF only.

A new method for absolute quantitation MRS metabolites (1997)

A new method for absolute quantitation of MRS spectra is presented. This method is not based on a reference peak, derived from a real NMR signal, but rather on a synthesized NMR reference produced by an electronic device, transmitted by a broad-band antenna to avoid quality factor variations. This signal is therefore received at the same time as the sample signal. The reference line produced is stable in time (maximum variation lower than 2%) and allows precise and accurate measurement of absolute concentrations (mean error lower than 3%) in vitro and in vivo.

Demethoxycurcumin in combination with ultraviolet radiation B induces apoptosis through the mitochondrial pathway and caspase activation in A431 and HaCaT cells (2017)

Photodynamic therapy is widely used in the clinical treatment of tumors, especially skin cancers. It has been reported that the photosensitizer curcumin, in combination with ultraviolet radiation B, induces HaCaT cell apoptosis, and this effect may be due to the activation of caspase pathways. In this study, we examined the photodynamic effects of demethoxycurcumin, a more stable analogue of curcumin, to determine whether it could induce apoptosis in skin cancer cells. We investigated the effects of a combination of ultraviolet radiation B and demethoxycurcumin on apoptotic cell death in A431 and HaCaT cells and determined the molecular mechanism of action. Our results showed increased apoptosis with a combination of ultraviolet radiation B with demethoxycurcumin, as compared to ultraviolet radiation B or demethoxycurcumin alone. The combination of ultraviolet radiation B irradiation with demethoxycurcumin synergistically induced apoptotic cell death in A431 and HaCaT cells through activation of p53 and caspase pathways, as well as through upregulation of Bax and p-p65 expression and downregulation of Bcl-2, Mcl-1, and nuclear factor-κB expression. In addition, we found that reactive oxygen species significantly increased with treatment, and mitochondrial membrane potential depolarization was remarkably enhanced. In conclusion, our data indicate that demethoxycurcumin may be a promising photosensitizer for use in photodynamic therapy to induce apoptosis in skin cancer cells.
Thermal transitions relating to gelling processes (1975)

Abstract The usefulness of differential scanning calorimetry (DSC) as a tool for studying thermal transitions in systems of biological origin is illustrated, using examples drawn from DSC studies of the gelation of the carrageenan polysaccharides.
A Weibo-Oriented Method for Unknown Word Extraction (2012)

Unknown word recognition is one of the most prominent and challenging problems in the Chinese language processing. Some effective approaches have been proposed, however, they do not work well on Chinese twitter (i.e. weibo) messages. In this paper, a method is presented to recognize unknown words from weibo. Due to the great flexibility in wording and highly correlation between unknown words and unpredictable topics, which are exhibited in weibo messages, the proposed method firstly groups the corpus into multiple categories by using K-means, then, from each of the categories, a morpheme set is derived based on local terms frequencies. Secondly, as for each potential unknown word in every morpheme set, a newly introduced measure (named adjacency degree) is calculated to see if a correct unknown word is found. It could be shown by the experiments that the proposed method is efficient, precise, and insensitive to the size of the weibo corpus.
Dithiocarbamates as Precursors in Organic Chemistry; Synthesis and Uses (2013)

Abstract Organic dithiocarbamates have received great attention due to their interesting chemistry and wide utility as radical precursors and intermediates in organic synthesis. They also have found many of applications, that is, in agriculture and medicine. They are in use as pesticides, as well as in the rubber industries as vulcanization accelerators; and as antioxidants. Because they exhibit strong metal-binding capacity, they can act as in inhibitors of enzymes and have a profound effect on biological systems. Moreover, they have found application in the treatment of cancer and HIV.
Accuracy of blood loss estimations among anesthesia providers. (2014)

Research regarding the accuracy of estimating blood loss by anesthesia providers has been limited, generally consisting of small sample sizes with conflicting findings. We conducted a prospective study using a convenience sample of 91 anesthesia providers: 36 Certified Registered Nurse Anesthetists (CRNAs), 48 student registered nurse anesthetists (SRNAs), and 7 anesthesiologists. We applied a known volume of moulage (theater) blood to items at 4 stations and asked each participant to estimate the amount of blood present at each station. Descriptive and inferential statistical analyses were performed. Multivariate regression analysis was conducted to evaluate the association of estimation errors with covariates (provider training, gender, ethnicity, years of education, and years of anesthesia experience). We found no difference in the mean error of blood loss estimation based on provider training, gender, ethnicity, education, or experience. Although no statistically significant differences in blood loss estimations existed among provider groups, CRNAs had smaller mean errors than anesthesiologists in all 4 stations and smaller mean errors than SRNAs in 3 of 4 stations. Accuracy of estimating blood loss, measured by mean error, was not related to type of provider training, years of education or experience, gender, or ethnicity. Anesthesia providers may not estimate blood loss accurately.
Testing an Improved Scintillation Camera for PET and SPECT (1986)

An extensive computer simulation has been completed to design a new type of scintillation camera for nuclear medicine. The aim of the design is to adapt the Anger camera to perform well at higher gamma energies, especially 511 keV. Such a design should provide an economic alternative to the small-crystal ring tomograph for PET, as well as improved efficiency for single photon ECT in the energy range 140-511 keV. A prototype has been constructed to test the new ideas arising from the design study. The prototype incorporates a 5 cm thick sodium iodide scintillator coupled to a rectangular array of 64 small photodetectors. Intrinsic position resolution measurements, as well as a variety of other measurements, have been performed at gamma-ray energies of 122 keV and 514 keV.
Comparative Efficacy of Two Angiotensin II Receptor Antagonists, Irbesartan and Losartan, in Mild-to-Moderate Hypertension (1998)

The primary objectives of this double-blind study were to compare the antihypertensive efficacy and tolerability of irbesartan and losartan, two angiotensin II (AT1 subtype) receptor antagonists with different pharmacokinetic profiles in patients with mild-to-moderate hypertension. Both drugs are approved for once-daily use (although losartan may also be prescribed twice-daily). After a placebo lead-in, 567 patients were randomized (1:1:1:1) to once-daily therapy with placebo, 100 mg losartan, 150 mg irbesartan, or 300 mg irbesartan for 8 weeks. Treatment groups had comparable demographic and baseline characteristics. After 8 weeks of treatment, reductions from baseline in trough seated diastolic blood pressure (SeDBP) and trough seated systolic blood pressure (SeSBP) with 300 mg irbesartan were greater than with 100 mg losartan (P < .01 for both comparisons), by 3.0 and 5.1 mm Hg, respectively; larger reductions were also demonstrated at weeks 1 and 4 (P < .01 and P = .017, respectively, for SeDBP). Throughout the study, the antihypertensive effect of 150 mg irbesartan did not differ significantly from that of 100 mg losartan. All therapies were well tolerated. The 300 mg dose of irbesartan was associated with the lowest incidence of adverse events (AE) and discontinuations because of AE. This study demonstrates that the maximally effective once-daily doses of two different AT1 receptor antagonists may result in clinically significant differences in blood pressure reductions, and therefore highlights the potential importance of the pharmacokinetic and pharmacodynamic differences between these two members of this class.

Chemical research--2000 and beyond: challenges and visions (1999)

In this volume, eminent scientists predict how chemistry will help meet the social, economic, and environmental challenges of the 21st century. This book collects essays from the American Chemical Society's New York Section special symposium Challenges and Visions: Chemical Reserach-2000 and Beyond held at Rockefeller University on October 1997.
Introduction. New Men: Feminist Histories of Manliness in Early British America (2016)

This introductory chapter provides an overview of the book's main themes. This book examines masculinity in British America from European settlement through the Revolutionary era. It argues that understandings of manliness significantly shaped the founding and development of early America. By focusing explicitly on the construction of manliness in early America, this book heeds the call of women's and gender scholars to deepen our understanding of the historical formation and deployment of gendered power in America. Within the broad understanding of masculinity in early America, the essays in this book examine how gender operated specifically in terms of oppositional identities, social interactions, and the cultural development of norms and ideals.
Decreased serum level of tumor necrosis factor in animals treated with lipopolysaccharide and liposomes containing phosphatidylserine. (1992)

The rise in serum level of tumor necrosis factor (TNF), produced by lipopolysaccharide, has been measured in mice and rabbits treated with phospholipid liposomes. After 3 daily ip injection (mice) or 5 daily i.v. injections (rabbits) of 30 mg/kg of a phospholipid mixture enriched in phosphatidylserine, the action of lipopolysaccharide was 80-90% reduced. The phospholipid effect is dose dependent, requires a minimum of two daily injections before the administration of lipopolysaccharide, and is still manifest 2 days after the last phospholipid dose. Among individual purified phospholipids, phosphatidylserine and phosphatidylethanolamine were effective whereas phosphatidylinositol, phosphatidylglycerol, and phosphatidylcholine did not show significant activity. The data indicate that the parenteral administration of liposomes containing the aminophospholipids phosphatidylserine, and phosphatidylethanolamine is an efficient mode to reduce the endotoxin-induced production of TNF. As suggested by liposome pharmacokinetics, this effect may be related to phospholipid accumulation in the mononuclear phagocyte system of liver and spleen.
Theoretical investigation of IL-6 multiprotein receptor assembly. (1997)

Interleukin-6 (IL-6) is a multifunctional cytokine that regulates cell growth, differentiation, and cellular functions in many cell lineages. Recently, evidences for the formation of an active hexameric complex with an IL-6:IL-6R alpha:gp130 stoichiometry of 2:2:2 have been obtained by different experimental approaches. Analysis of the electrostatic potential complementarity between IL-6 and its receptors has been used, in this study, to guide the assembly of homology-based 3D models of the components. The results strongly support a mechanism whereby the active cytokine (IL-6: IL-6R alpha) associates with the signal transducing gp130 protein, and the trimeric complex formed further dimerizes to form the hexameric species. Furthermore, computational simulations of the multiprotein complexes provide a rationalization of data from mutation experiments and highlight some key protein-protein interactions which have not yet been the subject of mutagenesis studies.
Dynamic arterial elastance to predict arterial pressure response to volume loading in preload-dependent patients (2011)

Functional assessment of arterial tone by Ea(dyn), measured as the PVV to SVV ratio, predicted arterial pressure response after volume loading in hypotensive, preload-dependent patients under controlled mechanical ventilation.
Acoustic Analysis (1981)

Acoustic analysis of voice patterns is an objective means of evaluating flatness of affect. Thirty-one patients defined as having flat affect by a reliable rating scale were compared with 30 patients who were not flat. The hypothesis that flat patients display monotonic speech was confirmed, for these patients showed less variance in both the amplitude and frequency of their speech than the nonflat patients.
Vulnerable Caregivers of Patients With Alzheimer's Disease Have a Deficit in Circulating CD62L- T Lymphocytes (1999)

The findings suggest that caregivers who are more vulnerable to the chronic stress of caregiving show a decrement in circulating CD62L- T lymphocytes, possibly by adrenomedullary activation. The data also suggest the identity of lymphocyte subsets that may underlie prior observations of immunologic decrements associated with the chronic stress of caregiving.
Monte Carlo simulation of impact ionization and current multiplication in short GaAs diodes (1997)

We have modelled carrier transport and impact ionization in bulk GaAs and GaAs diodes using two Monte Carlo models, one using analytical band structure, the other employing more realistic pseudopotential band structure. Despite the relative lack of sophistication of the analytical model and the poor representation of band structure at higher energies, the analytical model reproduced accurate drift velocities, mean energies and impact ionization rates in good agreement with experiment and the more sophisticated model. Both models accurately simulated the diodes, agreeing well with experimental results and the two models also agreed with each other with respect to the microscopic aspects of the carrier transport in these devices.
