Instrumental recording of electrophonic sounds from Leonid fireballs (2002)

Electrophonic meteor sounds, heard simultaneously with the meteor appearance, are a longstanding problem due to their nonintuitive nature. Previous investigations have been undermined by lack of instrumental recordings. Here we present the first instrumental detection of electrophonic sounds obtained during the observation of 1998 Leonids from Mongolia. Two Leonid fireballs of brightness −6.5 m and −12 m produced short, low‐frequency sounds, which were simultaneously recorded by microphones in a special setup and heard by different observers. Simultaneous measurements of electromagnetic ELF/VLF radiation above 500 Hz did not reveal any signal correlated to the electrophonic event. The lack of signal was explained by the low frequency of electrophones. We show that physical characteristics of Leonid electrophones cannot be completely explained by existing theories and that further theoretical refinement and observational work is needed. Finally, we tentatively suggest the possibility of stronger than expected coupling of fireballs with atmospheric charge dynamics and ionosphere.
Development of a slip and slide simulator for electric locomotive based on inverter-controlled induction motor (2009)

In this paper, a slip and slide simulator is proposed to simulate the dynamic behavior of the electric locomotive. The simulator consists of two inverter-controlled AC motors directly coupled with each other. One motor plays a role of traction motor of electric locomotive, other one is to use to simulate various driving characteristics of railway vehicle including adhesive characteristics, running resistance and gradient. First, the adhesive characteristics of wheel-rail system are analyzed and dynamic model of a single axle model of vehicle is presented in this paper. The torque-speed characteristics of a locomotive are physically implemented by an induction motor drive. Induction motor's torque is controlled by the indirect field oriented control strategy. In addition, a inverse dynamic model is adopted to simulate the dynamic mechanical performance of actual traction system which its inertia is larger than the testing system. At last the simulation results show that this scheme is viable and accurate.

Evaluation of Allelopathic Cucumbers (Cucumis sativus) as an Aid to Weed Control (1979)

Cucumber ( Cucumis sativus L.) accessions which had demonstrated allelopathy under controlled environmental conditions were evaluated in the field. Plant introduction (PI) 169391 suppressed proso millet ( Panicum miliaceum L.) fresh weight and population 58 and 84%, respectively. Total overseeded and volunteer weed population was reduced 54% when grown in association with PI 169391. Plant introduction 169391 was approximately twice as effective as PI 285605 in suppressing proso millet growth. Inhibition of weed species did not occur consistently in the field. The allelopathic effect of cucumbers was suppressed during periods of increased rainfall. However, these tests demonstrated that allelopathic activity could be obtained under certain edaphic and environmental conditions.
A NOVEL SUB-PIXEL MATCHING ALGORITHM BASED ON PHASE CORRELATION USING PEAK CALCULATION (2016)

The matching accuracy of homonymy points of stereo images is a key point in the development of photogrammetry, which influences the geometrical accuracy of the image products. This paper presents a novel sub-pixel matching method phase correlation using peak calculation to improve the matching accuracy. The peak theoretic centre that means to sub-pixel deviation can be acquired by Peak Calculation (PC) according to inherent geometrical relationship, which is generated by inverse normalized cross-power spectrum, and the mismatching points are rejected by two strategies: window constraint, which is designed by matching window and geometric constraint, and correlation coefficient, which is effective for satellite images used for mismatching points removing. After above, a lot of high-precise homonymy points can be left. Lastly, three experiments are taken to verify the accuracy and efficiency of the presented method. Excellent results show that the presented method is better than traditional phase correlation matching methods based on surface fitting in these aspects of accuracy and efficiency, and the accuracy of the proposed phase correlation matching algorithm can reach 0.1 pixel with a higher calculation efficiency.
Simulation and design of distillation units for treatment of sulfite pulping condensates to recover methanol and furfural: Part II: Applicability of multiple‐effect distillation using live steam (1979)

Abstract A distillation unit has been designed for a capacity of 73 t/h of condensate and for at least 90% recovery of the contaminating organics. This unit consists of three columns: a primary stripper to remove volatile organics and two upgrading columns to purify the methanol and furfural byproducts. Three different energy‐saving alternatives for satisfying the energy requirements have been studied: utilisation of secondary steam from the evaporation plant, and application of the principle of multi‐effect distillation in one‐stripper and in two‐stripper configurations. Investment cost needed in all alternatives amounts to 5.5–6.0 MCr (millions of Swedish Crowns) while operating cost varies between 0.8–3.1 MCr. The first design alternative has a payoff period of 2.3 years while the two multi‐effect distillation alternatives have a payoff period of about 3 years.
A framework for analysis of data freshness (2004)

Data freshness has been identified as one of the most important data quality attributes in information systems. This importance increases particularly in the context of distributed systems, composed of a large set of autonomous data sources, where integrating data having different freshness may lead to semantic problems. There are various definitions of data freshness in the literature, depending on the applications where they are used, as well as different metrics to measure them. This paper presents an analysis of these definitions and metrics and proposes a taxonomy based upon the nature of the data, the type of application and the synchronization policies underlying the multi-source information system. We analyze, in terms of the taxonomy, the way freshness is defined and used in several types of systems and we present some open research problems in the field of data freshness evaluation.
Use of green fluorescent protein for online, single cell detection of bacteria introduced into activated sludge microcosms (1998)

A derivative of broad host-range plasmid RP4 was tagged with the green fluorescent protein (GFP) and this construct was used to mark various Gram-negative bacteria. Video recording of combined phase contrast and epifluorescence microscopy was employed to track the fate of individual marked cells after introduction into a sludge microcosm. Whether the introduced bacteria were laboratory strains or activated sludge isolates. they were found to be rapidly eliminated from the microcosms as a result of intense predation by protozoa. Furthermore, a method was developed that allows detection of GFP-tagged bacteria in fixed samples that are simultaneously used for in situ hybridisation with a eukaryote-specific rRNA-targeted oligonucleotide probe for visualisation of protozoa.
Highly efficient method of preparing human catalytic antibody light chains and their biological characteristics (2011)

The ultimate goal of catalytic antibody research is to develop new patient therapies that use the advantages offered by human catalytic antibodies. The establishment of a high-throughput method for obtaining valuable candidate catalytic antibodies must be accelerated to achieve this objective. In this study, based on our concept that we can find antibody light chains with a high probability of success if they include a serine protease-like catalytic triad composed of Ser, His, and Asp on a variable region of the antibody structure, we amplified and cloned DNAs encoding human antibody light chains from germline genes of subgroup II by seminested PCR using two primer sets designed for this purpose. Seven DNA fragments encoding light chains in 17 clones were derived from germline gene A18b, 6 DNA fragments from A3/A19, 2 DNA fragments from A17, and a clone DNA fragment from A5 and O11/O1. All light chains expressed in Escherichia coli and highly purified under nondenaturing conditions exhibited amidolytic activity against synthetic peptides. Some of the light chains exhibited unique features that suppressed the infectious activity of the rabies virus. Furthermore, the survival rate of mice in which a lethal level of the rabies virus was coinoculated directly into the brain with light chain 18 was significantly improved. In the case of humans, these results demonstrate that high-throughput selection of light chains possessing catalytic functions and specificity for a target molecule can be attained from a light-chain DNA library amplified from germline genes belonging to subgroup II.

Fiberized fluorescent dye microtubes (2013)

In the present work we study the effect of the length of fluorescent dye-filled micro-capillaries on the fluorescence spectra. Two types of micro-capillaries have been studied: a 100 &mu;m inner diameter fused silica capillary with a transparent coating and one of the holes of a fiber optic glass ferrule with 125 &mu;m inner diameter. The tubes were filled with solutions of Rhodamine 6G dissolved in ethanol and then in glycerin. Experimental data show that the maximum fluorescence and the largest spectral widths are observed for a sample length of about 0.25 mm for the used concentration. This results show that miniature tunable fiberized dye lasers can be developed using available standard micro-and fibre-optic components.

Fast, Energy Efficient Scan inside Flash Memory. (2011)

Today, an SSD (Solid State Drive) is essentially a block device attached to a legacy host interface. As a result, the system I/O bus remains a bottleneck, and the abundant flash memory bandwidth as well as the computing capabilities inside SSD is largely untapped. In this paper, we motivate an efficient in-storage computing approach where (part of) data-intensive processing is moved from the host CPU to inside flash SSDs, close to the data source itself (“in-storage processing”). Especially, we focus on accelerating a key database operation, scan. To realize the idea in a cost-effective manner, we deploy special-purpose computing modules using the System-on-Chip technology. While data from flash memory are transferred, a target database operation is applied to the data stream on the fly without any delay. This reduces the amount of data to transfer to the host drastically, and in turn, ensures all components along the data path in an SSD are utilized in a balanced way. Our experimental results show that instorage processing outperforms conventional CPU based processing by over 13 times for scan operation. It also turns out that in-storage processing can offer sizable energy savings of up to 7×. This drastic performance improvement is mainly attributable to the parallelism inside single flash SSD, while the similar existing hard disk based approaches have not been such successful because of the limited I/O bandwidth provided by conventional hard disk.

Digital control with a flash ADC and a digital-to-current converter improve speed-power performance by 3X.
Correspondence Between Electronics and Fluids in MEMS: Designing Microfluidic Systems Using Electronics (2014)

It is well known that the classical laws of circuits have equivalents in fluid movement if certain conditions are met. Usually, equivalence with linear circuits requires laminar flow, which is a typical condition in a microelectromechanical system (MEMS). However, fluidic devices, which are nonlinear in nature, can also have an electronic counterpart, and the tools and procedures used in electronic design can be applied to microfluidic systems. A complete description of the electronic-fluidic correspondence, focused especially on MEMS, can increase the number of ways to design microfluidic networks and open new ways of operating them. The modeling of complex microfluidic networks, in particular, applications, demonstrate the usefulness of the analogy.

Transfection of mouse eggs and embryos using DNA combined to cationic liposomes (2000)

We have used plasmid DNA in combination with cationic liposomes to transfect mouse eggs and embryos. The plasmid was rhodamine labeled, which allowed a direct visualization of the DNA uptake by the cells. Immature eggs, collected from the ovaries, were easily transfected, but once the egg was ovulated the zona pellucida (ZP) acted as a barrier and prevented transfection. Permeabilization or removal of the ZP was therefore a requirement to allow transfection. Transfected eggs were capable of being fertilized in vitro giving raise to embryos that expressed the recombinant protein. Morulae and blastocysts were also transfected when the ZP was permeabilized, but the efficiency of transfection decreased and in some cases not all the blastomeres incorporated the plasmid. Pronuclear embryos were cultured and showed expression of the transgene from the 2-cell stage. This indicates that liposome-transfection of oocytes or pronuclear embryos could be a simple and suitable method to introduce foreign genes in embryos and perhaps could be also useful to generate transgenic animals.
Vitamin A Deficiency in Patients Undergoing Sleeve Gastrectomy and Gastric Bypass: A 2-Year, Single-Center Review (2019)

<b><i>Introduction:</i></b> Vitamin A deficiency (VAD) is an underreported micronutrient deficiency after bariatric surgery (BS). <b><i>Objectives:</i></b> The goal of this study was to characterize VAD prevalence in patients undergoing malabsorptive and restrictive procedures up to 2 years postoperatively. <b><i>Methods:</i></b> Primary sleeve gastrectomy (SG; <i>n</i> = 322) and gastric bypass (GB; <i>n</i> = 249) patients were reviewed. Levels for overall VAD (oVAD; retinol <39 mcg/dL) and moderate VAD (mVAD; retinol <30 mcg/dL) were reported preoperatively and 6, 12, and 24 months postoperatively. Differences in demographic, surgical, and postoperative data were tested between these groups. <b><i>Settings:</i></b> Single-center academic institution. <b><i>Results:</i></b> Serum retinol levels were documented for 56%, 74%, 61%, and 37% of patients for listed time points. Baseline retinol inversely correlated to preop body mass index (BMI) (<i>R</i> = -0.15, <i>P</i> = .007). Both oVAD and mVAD peaked 6 months postoperatively (33% vs. 15%, <i>P</i> < .005; 12% vs. 4%, <i>P</i> = .0004, respectively). oVAD remained elevated at 24 months (22% vs. 15%, <i>P</i> = .03). Compared to SG, oVAD was higher following GB at 6 months (39% vs. 28%, <i>P</i> = .001) and 12 months (26% vs. 17%, <i>P</i> = .04), and mVAD was greater with GB at 6 months (18% vs. 6%, <i>P</i> < .0005). African American patients had higher oVAD/mVAD preoperatively (26% vs. 13%, <i>P</i> = .02; 13% vs. 3%, <i>P</i> = .001, respectively) and at 6 months (19% vs. 10%, <i>P</i> = .04). Prior mild VAD (retinol 1.05-1.35 μM) was significantly associated with mVAD up to 12 months postoperatively. <b><i>Conclusions:</i></b> Although higher following LRYGB, VAD is prevalent following both malabsorptive and restrictive procedures. Preoperative serum retinol is inversely correlated to increasing BMI, and African American race and mild VAD are associated with moderate VAD.

Characterization of a model Ziegler–Natta catalyst for ethylene polymerization (2002)

Based on the work of the Somorjai group [Magni and Somorjai, Catal. Lett. 35, 205 (1995)] we have prepared a thin well ordered MgCl2(001) film by MgCl2 evaporation from a Knudsen cell. This film does not absorb TiCl4 at room temperature if it is not activated by increasing the defect density via electron or ion bombardment. The nature of some of the defects created is characterized by in situ ESR measurements and Auger spectroscopy. Paramagnetic surface defects are altered by the bonding of TiCl4 to the surface as observed by ESR spectroscopy. Ti3+ centers are detected if particularly severely defected MgCl2 layers are prepared. Reactivity studies show however, that these species are not correlated with polymerization activity. Interaction with aluminum alkyl leads to the formation of the active catalyst and we observe for the first time directly ethyl radicals formed from trimethyl-aluminum in an abstraction process which may be formulated as TiCl4/surface+AlMe3→Me−TiCl3/surface+AlMe2Cl, Me−TiCl3/surface→TiCl3/surface+Me⋅, and Me⋅+Me3Al→C2H5⋅+AlH(Me)2. The presence of the aluminum alkyl is observed via in situ IRAS in the same apparatus.
Effect of coercive force and characteristics of a pole changing permanent magnet motor for variable-speed drive (2014)

Energy savings in electrical appliances and electric vehicles can be realized by reducing the power consumption of motors operating for variable-speed drive. In order to reduce the energy consumption of such electrical devices, flux-weakening currents are used to reduce the voltage at high rotational speeds, which leads to significant copper and core losses. To counter this problem, we have developed a new technique that changes the number of poles in a permanent magnet (PM) motor based on the rotational speed. Therefore, we have proposed a PM motor that can vary its electrical machine constants to obtain high efficiency and an extensive rotational speed range. Herein, we describe the structure, pole changing magnetization mechanism, and basic characteristics of a novel pole changing PM motor, and present various characteristics of the motor over a wide rotational speed range. Furthermore, we also discuss the effect on the motor of the coercive force of the variable magnetized permanent magnet. The results of our study show that the proposed motor reduces core loss by about 50%, doubles the rotational speed range of the motor, and demonstrates high efficiency over a wide rotational speed range.

Difference engine (2010)

Virtual machine monitors (VMMs) are a popular platform for Internet hosting centers and cloud-based compute services. By multiplexing hardware resources among virtual machines (VMs) running commodity operating systems, VMMs decrease both the capital outlay and management overhead of hosting centers. Appropriate placement and migration policies can take advantage of statistical multiplexing to effectively utilize available processors. However, main memory is not amenable to such multiplexing and is often the primary bottleneck in achieving higher degrees of consolidation. Previous efforts have shown that content-based page sharing provides modest decreases in the memory footprint of VMs running similar operating systems and applications. Our studies show that significant additional gains can be had by leveraging both subpage level sharing (through page patching) and incore memory compression. We build Difference Engine , an extension to the Xen VMM, to support each of these---in addition to standard copy-on-write full-page sharing---and demonstrate substantial savings across VMs running disparate workloads (up to 65%). In head-to-head memory-savings comparisons, Difference Engine outperforms VMware ESX server by a factor 1.6--2.5 for heterogeneous workloads. In all cases, the performance overhead of Difference Engine is less than 7%.
