The hydrodynamic and acoustic behavior of bubble plumes generated by an impacting water jet (1991)

The preliminary results of an experimental study of the underwater sound field emitted by a bubble plume generated by dropping fixed volume of water, held in a cylindrical container, onto a still water surface were previously presented [J. Acoust. Soc. Am. Suppl. 1 88, 514 (1990)]. Further studies of the acoustic and hydrodynamic characteristics of the bubble plume are presented. The high-speed video images reveal the formation of a cylindrical plume that grows in length until all of the impacting water volume is injected into the still water. As the leading end of the plume advances, a “substructure” separates from the rest of the plume. The onset of the large-amplitude, low-frequency sound emission occurs at the instant the substructure detaches. The resonance frequencies of the densely populated substructures are inversely proportional to their radii and are highly dependent on the void fraction. Experimental results are presented which show that detached plumes undergo damped volume oscillations. The measured damping coefficients are found to be constant and are believed to be related to the thermal damping coefficient. The dependence of the detached plume diameters and undetached plume lengths on the containers radii, lengths, and heights above the still water level are also discussed.

Lineage and Virulence ofStreptococcus suisSerotype 2 Isolates from North America (2011)

We performed multilocus sequence typing of 64 North American Streptococcus suis serotype 2 porcine isolates. Strains were sequence type (ST) 28 (51%), ST25 (44%), and ST1 (5%). We identified nonrandom associations between STs and expression of the virulence markers suilysin (SLY), muramidase-relased protein (MRP), and extracellular factor (EF). Expression of pili encoded by the srtF and srtG pilus clusters was also nonrandomly associated with STs. ST1 strains were SLY+ EF+ MRP+ srtF pilus+ srtG pilus-. ST25 strains were SLY- EF- MRP- srtF pilus- srtG pilus+, and most ST28 strains were SLY- MRP+ EF- srtF pilus+ srtG pilus+. ST28 isolates proved essentially nonvirulent in a mouse infection model; ST25 strains showed moderate virulence and ST1 isolates were highly virulent. ST1 is responsible for a high proportion of S. suis disease in humans worldwide. Its presence in North America indicates that potential zoonotic S. suis outbreaks in this continent cannot be disregarded.
Large Active Area, High-Speed Photoreceiver for Optical Wireless Communications (2018)

We report a newly developed 45-Gbuad, 32-pixel two-dimensional photodetector array (2D-PDA) and the photodetector's performance in free space optical (FSO) communication. With the selected 4 × 4 pixels in 32 pixels to preserve large active area, the direct coupling between high data rate FSO beam and the 2D-PDA was demonstrated to improve optical alignment tolerances. The eye diagram, bit error rate (BER), and photo-current characteristics in the range 10-45 Gbaud were evaluated for 4 ×4 pixels in plane.
A Mobile Robot That Learns Its Place (1997)

We show how a neural network can be used to allow a mobile robot to derive an accurate estimate of its location from noisy sonar sensors and noisy motion information. The robot's model of its location is in the form of a probability distribution across a grid of possible locations. This distribution is updated using both the motion information and the predictions of a neural network that maps locations into likelihood distributions across possible sonar readings. By predicting sonar readings from locations, rather than vice versa, the robot can handle the very nongaussian noise in the sonar sensors. By using the constraint provided by the noisy motion information, the robot can use previous readings to improve its estimate of its current location. By treating the resulting estimates as if they were correct, the robot can learn the relationship between location and sonar readings without requiring an external supervision signal that specifies the actual location of the robot. It can learn to locate itself in a new environment with almost no supervision, and it can maintain its location ability even when the environment is nonstationary.
Use of two test methods to ensure accurate surface firmness and stability measurements for accessibility (2017)

The portable ISI can be used to verify that the firmness and stability of an installed surface in the field correlates to the accessibility results of the surface tested in the laboratory concurrently according to ASTM F1951 and the ISI. Implications for Rehabilitation The Instrumented Surface Indenter (ISI) allows for surfaces in all environments to be tested for firmness and stability, which is critical for wheelchair user safety, especially during rehabilitation when learning to use a wheelchair. The ISI allows for surfaces in all environments to be tested for firmness and stability, which increases access to all indoor and outdoor surfaces, thereby improving the quality of life for people who have mobility impairments and/or use mobility devices, such as canes, crutches, walkers, and wheelchairs. Using the ISI to test the firmness and stability of installed playground surfaces increases access to playgrounds for children with mobility impairments, facilitating developmentally critical peer-play opportunities for children who use mobility devices. Using the ISI to test the firmness and stability of installed playground surfaces increases access to playgrounds for people with mobility impairments, allowing adults who use a mobility device to supervise and play with children in their lives.

Comparing clean intermittent catheterisation and transurethral indwelling catheterisation for incomplete voiding after vaginal prolapse surgery: a multicentre randomised trial (2011)

Clean intermittent catheterisation is preferable over indwelling catheterisation for 3 days in the treatment of abnormal PVR following vaginal prolapse surgery.
Electrospray Tandem Mass Spectrometry of Nitrido and Imido Complexes (1996)

A number of high-valent nitrido and imido species of ruthenium, osmium, and chromium have been studied by electrospray tandem mass spectrometry. In each case, the mass spectrum shows the molecular ion as the base peak with a minimal degree of fragmentation. The collision-induced dissociation of these complexes may be interpreted in terms of the intrinsic metal−ligand bonds strengths, e.g. M⋮N > MO; M⋮N > MNR.
Entanglement transfer experiment in NMR quantum information processing (2002)

We report the implementation of an entanglement transfer on a four-qubit liquid-state nuclear-magnetic resonance quantum information processor. This consists of creating an (pseudopure) entangled state among two directly coupled spins, and then transferring this two-spin state to another pair of spins whose direct interactions are negligible. Such transfers are expected to be an essential operation in scalable quantum computer architectures, and provide a useful benchmark for the coherent control available in specific implementations.
SIRT1-dependent modulation of methylation and acetylation of histone H3 on lysine 9 (H3K9) in the zygotic pronuclei improves porcine embryo development (2017)

We conclude that SIRT1 modulates zygotic histone code, obviously through direct deacetylation and via non-histone targets resulting in increased H3K9me3. These changes in zygotes lead to more successful pre-implantation embryonic development and, indeed, the specific SIRT1 activation due to BML-278 is beneficial for in vitro embryo production and blastocyst achievement.
Self-Assembly of Single-Sized and Binary Colloidal Particles at Air/Water Interface by Surface Confinement and Water Discharge (2016)

We present an innovative apparatus allowing self-assembly at air/water interface in a smooth and reproducible way. The combination of water discharge and surface confinement of the area over which self-assembly takes place allows transfer of the assembled monolayer without any risk of damage to the colloidal crystal. As we demonstrate, the designed approach offers remarkable advantages in terms of cost and robustness compared to state-of-the art methods and is suitable for the fabrication of highly ordered monolayers even for more challenging assembly experiments such as transfer on rough substrates or assembly of binary colloids. Hence, our apparatus represents a significant headway toward high scale production of large area colloidal crystals. For the binary colloid assembly experiments, we also report the first experimental demonstration of a morphology based on the alternation of three and four small particles in the interstices between large particles.
A Metal-induced Conformational Change and Activation of HIV-1 Integrase (1997)

Retroviral integrases are composed of three independently folding domains whose organization relevant to one another is largely unknown. As an approach to understanding its structure, we have investigated the effect of the required metal cofactor(s), Mn2+ or Mg2+, on the conformation of human immunodeficiency virus type 1 (HIV-1) integrase (IN) using monoclonal antibodies (mAbs) that are specific for each of these three domains. Upon the addition of increasing concentrations of the divalent cations to immobilized HIV-1 IN in ELISA assays, binding of mAbs specific for either the C-terminal domain or for an epitope in the catalytic core domain was lost, whereas binding of an N terminus-specific mAb was unaffected. Size exclusion chromatography of a nonaggregating derivative of HIV-1 IN showed that the oligomeric state of the protein did not change under conditions in which recognition of the core and C terminus-specific mAbs was lost. Preincubation with Mn2+ increased the resistance of HIV-1 IN to proteolytic digestion and produced a digestion pattern that was significantly different from that observed with the apoprotein. A derivative that lacked the N-terminal domain, IN(50-288), exhibited the same metal-dependent changes observed with the full-length protein, whereas the isolated catalytic core domain IN(50-212) did not. From this we conclude that the metal-induced conformational change comprises a reorganization of the core and C-terminal domains. Preincubation with Mn2+ increased the specific activity of HIV-1 IN 5-fold. Enzymatic activity was inhibited by the conformation-sensitive C terminus-specific mAb, but this inhibition was reduced greatly if the enzyme was first preincubated with metal ions. Thus, it appears that apo-HIV-1 IN exists predominantly in an inactive conformation that is converted into a catalytically competent form upon the addition of metal ions.

Mix and match: A bipolar host material with hole-transport and electron-transport units was synthesized as the host material for deep-blue phosphorescent organic light-emitting diodes and was compared with other mixed-host materials with the same core structure. The bipolar host material showed similar current density and quantum efficiency to those of the mixed host.

Dielectric Properties (2017)

Abstract In this chapter, we deal with the basic theory of linear dielectric response in solids, since the linear dielectric permittivity and losses are basic parameters that control the performance of many electronic devices. After a short introduction to some prominent applications, basic definitions are given and the behavior of a dielectric slab in an electric field is described. Then the various mechanisms causing polarization in solids are discussed from the macroscopic and the microscopic viewpoints, noting the concept of the local electric field. Polarization mechanisms are distinguished by their characteristic temperature and frequency dependencies leading to relaxation and resonance phenomena. Describing the interaction of phonons with the electric field finally gets us to the concept of polarization waves in ionic crystals.
Supercharged CO 2 Photothermal Catalytic Methanation: High Conversion, Rate, and Selectivity (2023)

Abstract To overcome the thermodynamic and kinetic impediments of the Sabatier CO 2 methanation reaction, the process must be operated under very high temperature and pressure conditions, to obtain an industrially viable conversion, rate, and selectivity. Herein, we report that these technologically relevant performance metrics have been achieved under much milder conditions using solar rather than thermal energy, where the methanation reaction is enabled by a novel nickel‐boron nitride catalyst. In this regard, an in situ generated HOB⋅⋅⋅B surface frustrated Lewis's pair is considered responsible for the high Sabatier conversion 87.68 %, reaction rate 2.03 mol g Ni −1 h −1 , and near 100 % selectivity, realized under ambient pressure conditions. This discovery bodes well for an opto‐chemical engineering strategy aimed at the development and implementation of a sustainable ‘Solar Sabatier’ methanation process.
Performance of a 512 x 512 gated CMOS imager with a 250 ps exposure time (2012)

We describe the performance of a 512x512 gated CMOS read out integrated circuit (ROIC) with a 250 ps exposure time. A low-skew, H-tree trigger distribution system is used to locally generate individual pixel gates in each 8x8 neighborhood of the ROIC. The temporal width of the gate is voltage controlled and user selectable via a precision potentiometer. The gating implementation was first validated in optical tests of a 64x64 pixel prototype ROIC developed as a proof-of-concept during the early phases of the development program. The layout of the H-Tree addresses each quadrant of the ROIC independently and admits operation of the ROIC in two modes. If “common mode” triggering is used, the camera provides a single 512x512 image. If independent triggers are used, the camera can provide up to four 256x256 images with a frame separation set by the trigger intervals. The ROIC design includes small (sub-pixel) optical photodiode structures to allow test and characterization of the ROIC using optical sources prior to bump bonding. Reported test results were obtained using short pulse, second harmonic Ti:Sapphire laser systems operating at &lambda;~ 400 nm at sub-ps pulse widths.
Polarized Light Imaging of Biological Tissues (2011)

A common use of polarized light in medicine is the dermatologist using a dermatoscope that delivers linearly polarized light to the skin, while the dermatologist views through a linearly polarization lter that is cross-polarized, that is, oriented so it blocks the illumination light. Consequently, only light that penetrates the skin is randomized by propagation in the skin, such that half the light is now co-polarized with the viewing lter and will reach the eye of the dermatologist (Anderson 1991). is technique removes the glare from the skin surface. Alternatively, turning the viewing polarizer to be parallel with the orientation ofthe polarized illumination light will accent the surface glare and block half the multiply scattered light from the skin, allowing the dermatologist to better view the surface irregularities of the skin.
A Simplified Methodology for Comparing Fatigue Loading on Subsea Wellheads (2013)

This paper presents a simplified way of comparing the fatigue load on different subsea wells. The simplest comparison is done by accumulating the number of days BOP has stayed connected to the wellhead. The wellhead fatigue load is however heavily dependent on the vessels used, water depth and weather while connected to the well. An equation for deriving a benchmark load factor for each operation phase for a subsea well is proposed. This benchmark load factor takes into account the water depth, metocean season of the operation, BOP height and weight, and the stiffness of the marine riser lower flex joint. This benchmark load factor will represent a standard number of days with a BOP connected, correcting for some known effects. The goal has been to define a measure of ‘BOP days’ that accounts for the water depth, operational season, and BOP particulars. A base case (one MODU, 100 m water depth, and all year operation), equating to one standard BOP day, has been chosen as the reference for all cases discussed. The validity of the benchmark load equation will be shown through a comparison with 31 different global riser analyses intended for wellhead fatigue. For each of the 31 data sets, time domain load analysis is done for all sea states in the wave scatter diagram. The different analyses covers different rigs, water depths and two operational phases (with or without subsea XT installed). To enable a large scale comparison of the bench mark factor, an approach where the fatigue load is summarized using the bending moment standard deviation on the wellhead datum is presented. This methodology is then compared to four full fatigue calculations using a typical subsea wellhead fatigue capacity. Then the simplified fatigue calculation is performed for all 31 global riser analyses. The calculated damage is then compared with the corresponding bench mark formula in each case. Finally it is shown how this benchmark load formula has been implemented into the Statoil WellSpot database as a fatigue load criticality screening tool for the different Statoil subsea wells. It is further shown how this can be used as a tool during planning of future operations, and how to prioritize wells where a detailed fatigue analysis is recommended.
Thermofluid Analysis of Magnetocaloric Refrigeration (2019)

While there have been extensive studies on thermofluid characteristics of different magnetocaloric refrigeration systems, a conclusive optimization study using non-dimensional parameters which can be applied to a generic system has not been reported yet. In this study, a numerical model has been developed for optimization of active magnetic refrigerator (AMR). This model is computationally efficient and robust, making it appropriate for running the thousands of simulations required for parametric study and optimization. The governing equations have been non-dimensionalized and numerically solved using finite difference method. A parametric study on a wide range of non-dimensional numbers has been performed. While the goal of AMR systems is to improve the performance of competitive parameters including COP, cooling capacity and temperature span, new parameters called “AMR performance index-1” have been introduced in order to perform multi objective optimization and simultaneously exploit all these parameters. The multi-objective optimization is carried out for a wide range of the non-dimensional parameters. The results of this study will provide general guidelines for designing high performance AMR systems.

Effect of epidermal growth factor and insulin-like growth factor I on porcine preantral follicular growth, antrum formation, and stimulation of granulosal cell proliferation and suppression of apoptosis in vitro1 (2004)

The object of this study was to investigate the role of epidermal growth factor (EGF) and IGF-I in the regulation of preantral follicular growth, antrum formation, and granulosal cell proliferation/ apoptosis. Porcine preantral follicles were manually dissected and cultured for up to 8 d in Waymouth's (Exp. 1) or alpha-minimum Eagle's essential medium (Exp. 2 and 3) supplemented with 10 microg/mL of transferrin, 100 microg/mL of L-ascorbic acid, and 2 mU/mL of ovine FSH, in the presence (Exp. 1 and 3) or absence (Exp. 2) of 7.5% fetal calf serum. According to the experimental protocol, IGF-I (0, 1, 10, or 100 ng/mL; Exp. 1), or IGF-I (50 ng/mL), EGF (10 ng/mL) and EGF+IGF-I (Exp. 2 and 3) were added to the culture media. In Exp. 1, follicles exhibited a concentration-dependent response (P < 0.05) to IGF-I, with the highest rates of granulosal cell proliferation, follicular integrity, and recovery rate of cumulus cell-oocyte complexes and lowest incidence of apoptosis occurring at the highest IGF-I dose. In Exp. 2 serum-free medium, granulosal cell proliferation was low (1 to 5%), irrespective of whether EGF and/or IGF-I were present and cellular apoptosis was increased (P < 0.05) on d 4 and 8 in the EGF+IGF-I group compared with the addition of either factor alone. In Exp. 3, granulosal cell proliferation was high in all follicles cultured in serum-containing medium for the first 3 d, but fell sharply (P < 0.05) on d 4, except in media containing IGF-I. Collectively, EGF and IGF-I increased granulosal cell proliferation, decreased apoptosis, and promoted follicular antrum formation. These results may provide useful information for developing a preantral follicular culture system in which the oocytes are capable of fertilization and embryonic development.
Discriminative reranking of ASR hypotheses with morpholexical and N-best-list features (2011)

This paper explores rich morphological and novel n-best-list features for reranking automatic speech recognition hypotheses. The morpholexical features are defined over the morphological features obtained by using an n-gram language model over lexical and grammatical morphemes in the first-pass. The n-best-list features for each hypothesis are defined using that hypothesis and other alternate hypotheses in an n-best list. Our methodology is to align each hypothesis with other hypotheses one by one using minimum edit distance alignment. This gives us a set of edit operations - substitution, addition and deletion as seen in these alignments. These edit operations constitute our n-best-list features as indicator features. The reranking model is trained using a word error rate sensitive averaged perceptron algorithm introduced in this paper. The proposed methods are evaluated on a Turkish broadcast news transcription task. The baseline systems are word and statistical sub-word systems which also employ morphological features for reranking. We show that morpholexical and n-best-list features are effective in improving the accuracy of the system (0.8%).
