Energy Transfer Among Like and Unlike Molecules in Solution VI. Effect of the Mediation of Donor Molecules Upon the Electronic Excitation Energy Transfer in Binary Systems (1982)

Abstract The effect of an interdonor energy transfer is investigated on the following donor-acceptor systems in thin rigid cellulose acetate films: anthracene and tetracene (I), 9-methylanthracene and 2-aminobenzophenone (II), 9,10-diphenylanthracene and 2-aminobenzophenone (III). The donor quantum yield and fluorescence anisotropy in systems I-III are in good agreement with theoretical predictions for a model of a multi-step excitation energy transfer process. In mixed two-component solutions the donor fluorescence anisotropy is higher than in single-component solutions, indicating an interdonor excitation transfer preceding the donor-acceptor transfer in these binary systems.
Peripheral-Type Benzodiazepine Receptors Are Highly Concentrated in Mitochondrial Membranes of Rat Testicular Interstitial Cells (1990)

The binding of 3H-RO 5-4864 to the peripheral-type benzodiazepine receptors (PBZDR) in rat testicular interstitial cells (TIC) was characterized. The binding was saturable, reversible and showed a single high-affinity (Kd = 5.02 +/- 0.86 nM) class of binding sites. The maximal binding capacity (Bmax) in crude mitochondrial fractions (77.6 +/- 9.1 pmol/mg protein) represents the highest density of PBZDR in tissues thus far studied. In comparison with the crude mitochondrial fraction the subcellular fractionation of TIC revealed a 2-fold enrichment of 3H-RO 5-4864 binding sites to the purified mitochondria (Bmax = 140 +/- 23 pmol/mg protein). The ability of various drugs to displace 3H-RO 5-4864 from TIC binding sites was examined and the inhibition constants (Ki) for RO 5-4864, PK 11195, diazepam and flunitrazepam were 3.5, 4.4, 159, and 353 nM, respectively, whereas clonazepam and RO 15-1788 were inefficient in displacing 3H-RO 5-4864 (Ki greater than 10 microM). This pharmacological profile is characteristic of PBZDR described in other tissues. In conclusion, rat TIC possess a very high concentration of PBZDR primarily associated with mitochondrial membranes.
Checklist for early recognition and treatment of acute illness: International collaboration to improve critical care practice (2015)

Processes to ensure world-wide best-practice for critical care delivery are likely to minimize preventable death, disability and costly complications for any healthcare system's sickest patients, but no large-scale efforts have so far been undertaken towards these goals. The advances in medical informatics and human factors engineering have provided possibility for novel and user-friendly clinical decision support tools that can be applied in a complex and busy hospital setting. To facilitate timely and accurate best-practice delivery in critically ill patients international group of intensive care unit (ICU) physicians and researchers developed a simple decision support tool: Checklist for Early Recognition and Treatment of Acute Illness (CERTAIN). The tool has been refined and tested in high fidelity simulated clinical environment and has been shown to improve performance of clinical providers faced with simulated emergencies. The aim of this international educational intervention is to implement CERTAIN into clinical practice in hospital settings with variable resources (included those in low income countries) and evaluate the impact of the tool on the care processes and patient outcomes. To accomplish our aims, CERTAIN will be uniformly available on either mobile or fixed computing devices (as well as a backup paper version) and applied in a standardized manner in the ICUs of diverse hospitals. To ensure the effectiveness of the proposed intervention, access to CERTAIN is coupled with structured training of bedside ICU providers.

Cephalothin, a New Cephalosporin with a Broad Antibacterial Spectrum (1963)

Cephalothin is 7-(thiophene-2-acetamido) cephalosporanic acid; it was prepared by N-acylation of the nucleus of cephalosporin C, 7-aminocephalosporanic acid. Cephalothin had a broad spectrum of antibiotic activity that was essentially unaffected by human serum or inoculum level, the activity of penicillinase, or pH variation of the growth medium. In vitro development of resistance by staphylococci could not be demonstrated, but the gram-negative organisms did develop a stepwise type of resistance to the antibiotic. Staphylococci made resistant in vitro to 5-methyl-3-phenyl-4-isoxazole penicillin were also resistant to cephalothin and to 6-(2,6-dimethoxybenzamido) penicillin; however, the mechanism of resistance to each antibiotic may have differed. Some complications involved in the laboratory evaluation methods currently in use in the field of antibiotics are examined.

In this paper we describe how microautoradiography (MAR) and fluorescent in situ hybridization (FISH) can be used to characterize and enumerate functionally important groups of microorganisms in activated sludge. The principles for the methods, some important methodological aspects and limitations of the procedures and some important results are discussed. Special focus is on the examination of the in situ physiology of certain filamentous microorganisms and a discussion about the use of such information in mathematical models of the activated sludge processes.

Rabbit skeletal muscle glycogen synthase. II. Enzyme phosphorylation state and effector concentrations as interacting control parameters. (1976)

The effects of several inhibitors (ATP, ADP, AMP, UDP, and P1) and activators (Mg2+, glucose-6-P) of rabbit muscle glycogen synthase (UDP-glucose:glycogen 4-alpha-glucosyltransferase, EC 2.4.1.11) were studied in relation to the phosphorylation state of the purified enzyme. All the modifiers had increasing effects with enzyme of increasing alkali-labile phosphate content. In experiments where combinations of effectors were present, it was apparent that (a) concentrations of modifiers in the physiological range could be significant in determining enzymic activity and (b) the sensitivity of the reaction rate to changes in phosphorylation state was critically dependent on the concentration of the small molecules. Changes in the phosphorylation of the enzyme corresponding to changes in the %I activity reported in the literature for studies in vivo were capable of producing large alterations in glycogen synthase activity. Because the magnitudes of such changes were dependent on the effector concentrations, there may be an integration of local cellular control, through small molecule effects, with hormonal control, through the phosphorylation state of glycogen synthase.
Error-free all-optical demultiplexing at 160Gb/s via FWM in a silicon nanowire (2010)

We demonstrate all-optical time division demultiplexing from 160Gb/s to 10Gb/s in the C-band, based on four-wave mixing (FWM) in a silicon nanowire. We achieve error-free operation with a system penalty of ~ 3.9dB at 10−9 BER.
Dynamic simulation of non-penetrating flexible bodies (1992)

A model for the dynamic simulation of flexible bodies subject to non-penetration constraints is presented. Flexible bodies are described in terms of global deformations of a rest shape. The dynamical behavior of these bodies that most closely matches the behavior of ideal continuum bodies is derived, and subsumes the results of earl ier Lagrangian dynamics-based models. The dynamics derived for the flexible-body model allows the unification of previous work on flexible body simulation and previous work on non-penetrating rigid body simulation. The non-penetration constraints for a system of bodies that contact at multiple points are maintained by analytically calculated contact forces. An implementation for first-and second-order polynomially deformable bodies is described. The simulation of second-order or higher deformations currently involves a polyhedral boundary approximation for collision detection purposes,
Photo-oxygenation of benzene derivatives by a novel derivative of the heterocyclic N-oxide, pyrimido[5,4-g]pteridine 5-oxide, involving a single-electron-transfer process (1990)

1,3,7,9-Tetrabutylpyrimido[5,4-g]pteridine-2,4,6,8(1H,3H,7H,9H)-tetrone 5-oxide (1) efficiently oxygenates benzene (4a), toluene (4b), and anisole (4c) under photochemical conditions in a reaction mode different from that of 3-methylpyridazine 2-oxide (3) to give the corresponding phenols (5a–c) as major products. Experimental results clearly indicate that the photochemical oxygenation of (4a–c) by (1) involves a single-electron-transfer process followed by oxygen-atom transfer rather than interception of atomic oxygen generated from (1) in an excited state.
Influence of Surface Modifications on the Spatiotemporal Microdistribution of Quantum Dots In Vivo (2016)

For biomedical applications of nanoconstructs, it is a general prerequisite to efficiently reach the desired target site. In this regard, it is crucial to determine the spatiotemporal distribution of nanomaterials at the microscopic tissue level. Therefore, the effect of different surface modifications on the distribution of microinjected quantum dots (QDs) in mouse skeletal muscle tissue has been investigated. In vivo real-time fluorescence microscopy and particle tracking reveal that carboxyl QDs preferentially attach to components of the extracellular matrix (ECM), whereas QDs coated with polyethylene glycol (PEG) show little interaction with tissue constituents. Transmission electron microscopy elucidates that carboxyl QDs adhere to collagen fibers as well as basement membranes, a type of ECM located on the basolateral side of blood vessel walls. Moreover, carboxyl QDs have been found in endothelial junctions as well as in caveolae of endothelial cells, enabling them to translocate into the vessel lumen. The in vivo QD distribution is confirmed by in vitro experiments. The data suggest that ECM components act as a selective barrier depending on QD surface modification. For future biomedical applications, such as targeting of blood vessel walls, the findings of this study offer design criteria for nanoconstructs that meet the requirements of the respective application.
ASCA Observations of the Composite Warm Absorber in NGC 3516 (1996)

We obtained X-ray spectra of the Seyfert 1 galaxy NGC 3516 in 1995 March using the Japanese X-ray satellite, ASCA. Simultaneous far-UV observations were obtained with the Hopkins Ultraviolet Telescope on the Astro-2 shuttle mission. The ASCA spectrum shows a lightly absorbed power law of energy index 0.78. The low-energy absorbing column is significantly less than previously seen. Prominent O VII and O VIII absorption edges are visible, but, consistent with the much lower total absorbing column, no Fe K absorption edge is detectable. A weak, narrow Fe Kα emission line from cold material is present as well as a broad Fe Kα line. These features are similar to those reported in other Seyfert 1 galaxies. A single warm absorber model provides only an imperfect description of the low-energy absorption. In addition to a highly ionized absorber with ionization parameter U = 1.66 and a total column density of 1.4 x 10^22^ cm^-2^, adding a lower ionization absorber with U = 0.32 and a total column of 6.9 x 10^21^ cm^-2^ significantly improves the fit. The contribution of resonant line scattering to our warm absorber models limits the Doppler parameter to less than 160 km s^- 1^ at 90% confidence. Turbulence at the sound speed of the photoionized gas provides the best fit. None of the warm absorber models fitted to the X-ray spectrum can match the observed equivalent widths of all the UV absorption lines. Accounting for the X-ray and UV absorption simultaneously requires an absorbing region with a broad range of ionization parameters and column densities.

A net draft tube slurry airlift bioreactor for 2,4‐D (2,4‐dichlorophenoxyacetic acid) pesticide biodegradation (2010)

Abstract Biodegradation of the pesticides 2,4‐D have been investigated in a net draft tube airlift bioreactor at different concentrations (10–160 ppm) and air flow rates (0.75–4 L min −1 ), employing acclimatised activated sludge. A modification for the glass draft tube airlift bioreactor was proposed in which the draft tube is made of non‐woven polypropylene textile net. The experiments were carried out as well in a bubble column (BC) for comparison. The results confirmed that immobilising the activated sludge on the net of the draft tube could enhance the substrates mass transfers and improve the biodegradation rate. A mathematical model was developed to simulate the biodegradation process. The simulated results were in good agreement with the experiments.
Decoding Visual Stimulus in Semantic Space from Electrocorticography Signals (2018)

Recent studies using functional magnetic resonance imaging (fMRI) have enabled quantitative evaluation of the semantic space during processing of visual stimuli. In the semantic space of the natural language processing model, called a skip-gram, decoders were shown to generalize to natural scenes of a movie that was not included in the training data of the decoders. Combined with electrocorticography (ECoG), which has a higher sampling rate than fMRI, this approach is expected to aid the development of a practical brain-machine interface. Here, we decoded vector representations of scenes within the semantic space of a skip-gram model to assess whether a decoder trained using ECoG features still generalizes to scenes new to the decoder.

Tseudo‐lymphoid‘ leukaemia with unusual features: Ultrastructural, immunological, cytogenetic and molecular studies (1987)

An unusual case of 'pseudo-lymphoid' leukaemia is described. The leukaemic cells resembled small, mature lymphocytes but lacked B- and T-cell membrane markers as well as immunoglobulin (Ig) and T-cell receptor gene rearrangements. They showed, instead, features of early myeloid cells since they expressed 2 myeloid antigens, CDW13 and My9, and displayed peroxidase activity demonstrable by electron microscopy (EM) on unfixed cells. Cytogenetic studies showed monosomy 5, t(4;17) (p12;p11), t(2;3)(p23;q14) and an abnormal chromosome 12. Abnormalities of chromosomes 4 and 5 have been previously associated with 'pseudo-lymphoid' leukaemias. This case illustrates the value of sensitive methods for the characterization of blast cells and for the precise diagnosis of leukaemias with apparent 'lymphoid' morphology.
ARROW: An Efficient Traffic Scheduling Algorithm for IEEE 802.11e HCCA (2006)

In this paper we present a novel traffic scheduling algorithm for IEEE 802.11e, referred to as ARROW (adaptive resource reservation over WLANs), which aims at providing improved performance for the support of multimedia traffic. The novel characteristic of this algorithm, compared to previous proposals, is that it performs channel allocations based on the actual traffic buffered in the various mobile stations, i.e., on the exact transmission requirements. This feature renders ARROW ideal for variable bit rate traffic. However, an enhancement is also presented that improves ARROW performance under constant bit rate traffic. The ARROW algorithm and its enhancement are discussed and evaluated against two other schedulers found in the open technical literature, namely the simple scheduler and SETT-EDD. Results from a detailed simulation model verify that ARROW provides much better channel utilization and considerably improved performance, in terms of mean delay and packet loss
Distortion generated by a moving weld pool of elliptical cross section in the welding of thin metal sheets (2000)

Much analytical work exists dealing with distortion in thin metallic sheets produced by moving heat sources. We consider here the case of the distortion generated in a weld pool whose cross section is in the form of an ellipse in a thin sheet of metal, but with some allowance for variations through the thickness of the material. An essential feature is the presence of this molten pool. The presence of the molten region ensures that stresses arising from viscous flow and pressure are many orders of magnitude smaller then those present in the solid region and can therefore be neglected. In the present analysis all deformations that arise are associated with the equations of linear thermoelastic theory. The problem is tackled analytically and expressions obtained for the stresses in the work piece.
