Early Development of Optical Low-Coherence Reflectometry and Some Recent Biomedical Applications (1999)

This paper explains the term low-coherence interferometry, reviews the early development of optical low-coherence reflectometry, and shows some of the paths that led to the field of biomedical optics. This paper demonstrates that early technical developments in the telecommunications industry resulted in a myriad of technical implementations and applications in biology, medicine, and the explosion of the field in noninvasive biomedical optical techniques. Recent examples of innovative applications of this proliferating technology into the fields of ophthalmology, developmental biology, and endoscopy are described. © 1999 Society of Photo-Optical Instrumentation Engineers.
Complications of Spinal Cord Stimulation and Peripheral Nerve Stimulation Techniques: A Review of the Literature (2015)

Spinal cord and peripheral neurostimulation techniques are safe and reversible therapies. Hardware-related complications are more commonly observed than biological complications. Serious adverse events such as neurological damage are rare.
Optical asymmetrical median filtering using gray-scale convolution kernels (1990)

Morphological transformations such as erosion and dilation can be performed optically by convolving the binary input image with a binary kernel and then passing the result through an ideal thresholder-hardlimiter. Generalizations result from using gray-scale convolution kernels. It is shown that gray-scale kernels can be used to perform transformations similar to openings and closing with just one convolution instead of the ususal cascade of erosion and dilation normally required for these operations. Optical experimental results are presented.
Improved diagnosis of Ziehl-Neelsen smear negative tuberculosis using sodium hypochlorite sedementation method (2008)

Overnight sedimentation using 3.5% NaOC1 significantly improves diagnosis of ZN smear negative TB. This technique has potential to improve diagnosis in TB diagnostic services especially in settings with high burden of dual TB/HIV infection.
A system for routing arbitrary communication graphs on simd architectures (1986)

There is a class of problems that can be loosely called connected information problems. This class includes areas such as semantic networks, data base processing, VLSI circuit simulation, topological processing, and many general graph theoretic problems. These problems are characterized by points of information connected to other points (or nodes in a graph connected by arcs), and it is desirable to traverse many paths in the graph simultaneously. Typically, the real-world version of these problems are very large, containing thousands or hundreds of thousands of nodes. These problems are not well suited to current methods of serial computation.
As the possibility of having massive parallelism is quickly approaching reality, it is necessary to ask what kind of machine would best solve these problems. A natural way to attack these problems on a parallel system would be to assign each information point to a processor. This solution has a great deal of appeal but has several architectural requirements. The first one is that many processors are needed--on the order of hundreds of thousands. It is also necessary to have a way to realize the edges. These two requirements conflict. Currently, MIMD computers being developed have a few dozen to a few hundred processors that generally have robust communication links, but they do not lend themselves to the concept of having one processor per vertex. SIMD machines can and have been built with large numbers of processors. However, the communication problem is much more difficult, and for this reason they have been essentially ignored as a reasonable means for handling general graph problems.
The paper will present a simple SIMD architecture model that is bit-serial and uses only nearest neighbor connections for communication. Several algorithms are given that will be used to implement communication between arbitrary points. This architecture and algorithm defines a system that is relatively simple to build, but can do connected information processing. It will decide on the placement of data items and construct paths through the nearest neighbors to join these items. It does this automatically. All connections can be traversed in parallel in time O(diameter). Modifying or adding a new connection takes the same time as parallel traversal.
One of the methods of observing ESD around electronic equipments (2005)

It is very difficult to discriminate between interferences caused by ESD (emanated electromagnetic impulse) and others on electronic equipments. In this paper, we show the method to discriminate between them and to observe ESD, with giving details of "ESD Impulse Monitor" and practical use of it. We could find the origin of ESD with the measurement equipment and performed countermeasure to prevent it. As a result, the number of equipment failures was reduced 26% in comparison to before countermeasure.
Pb<sub>1-x</sub>Sn<sub>x</sub>Te/PbTe<sub>1-y</sub>Se<sub>y</sub>lattice-matched buried heterostructure lasers with CW Single mode output (1980)

The first successful realization of buried heterostructure diode lasers in the PbSnTe/PbTeSe system is reported. This has resulted in routine cw operation above 80 K with threshold currents as low as 60 mA in 5 µm wide stripe lasers. CW operation has been achieved to 120K. In addition, these lasers operate in the fundamental transverse mode up to as much as four times threshold.
Mutational analysis of human DNase I at the DNA binding interface: Implications for DNA recognition, catalysis, and metal ion dependence (1998)

Human deoxyribonuclease I (DNase I), an enzyme used to treat cystic fibrosis patients, has been systematically analyzed by site-directed mutagenesis of residues at the DNA binding interface. Crystal structures of bovine DNase I complexed with two different oligonucleotides have implicated the participation of over 20 amino acids in catalysis or DNA recognition. These residues have been classified into four groups based on the characterization of over 80 human DNase I variants. Mutations at any of the four catalytic amino acids His 134, His 252, Glu 78, and Asp 212 drastically reduced the hydrolytic activity of DNase I. Replacing the three putative divalent metal ion-coordinating residues Glu 39, Asp 168, or Asp 251 led to inactive variants. Amino acids Gln 9, Arg 41, Tyr 76, Arg 111, Asn 170, Tyr 175, and Tyr 211 were also critical for activity, presumably because of their close proximity to the active site, while more peripheral DNA interactions stemming from 13 other positions were of minimal significance. The relative importance of these 27 positions is consistent with evolutionary relationships among DNase I across different species, DNase I-like proteins, and bacterial sphingomyelinases, suggesting a fingerprint for a family of DNase I-like proteins. Furthermore, we found no evidence for a second active site that had been previously implicated in Mn2+-dependent DNA degradation. Finally, we correlated our mutational analysis of human DNase I to that of bovine DNase I with respect to their specific activity and dependence on divalent metal ions.

5T4 oncotrophoblast glycoprotein: janus molecule in life and a novel potential target against tumors. (2007)

5T4 oncotrophoblast glycoprotein is a transmembrane protein expressed on the embryonic tissue and various malignant tumor cell surfaces. It plays a vital role in the multiple biological and pathological processes including massive cellular migration during the embryogenesis, cell invasion associated with implantation, and neoplastic metastasis in the progression of tumorigenesis. Its restricted profile of expression stratifies criteria of tumor-associated antigen and makes it a new promising candidate for immunotherapy for cancer. Hence, illustrating this molecular function is necessary for discovering the principle of the tumor diffusion and aggravation and is helpful for developing novel and effective strategies of cancer therapy.
Physicochemical Properties of Heme Iron Products in the Korean Market (2006)

Since absorption efficacy of heme iron (HI) is critically dependent on its solubility in aqueous solution, we investigated the physicochemical properties of two HI products available in the Korean market. The two HI products did not differ in ingredients and color. However, HI polypeptide (HIP), produced in Korea, was fairly soluble over a wide pH range in water-based solutions, whereas HI imported from Japan was insoluble except in strong acid and base solutions. Analysis using an ultraviolet-visible spectrophotometer showed that the chromophore of HIP was shifted to the red compared with that of HI. Fourier transform-infrared analysis revealed that HIP contained mainly amide (NH) groups, while HI largely contained amine (NH(2)) groups. With regard to constituents, between HIP and HI, their major components were different from each other according to their ratio of fronts obtained by thin-layer chromatography. These results suggest that determination of solubility should be included in the quality control process of HI products.
Non-degenerate fs pump-probe study on InGaN with multi-wavelength second-harmonic generation (2005)

Non-degenerate fs pump-probe experiments in the UV-visible range for ultrafast carrier dynamics study of InGaN with adjustable pump and probe photon energies are implemented with simultaneously multiwavelength second-harmonic generation (SHG) of a 10 fs Ti:sapphire laser. The multi-wavelength SHG is realized with two beta-barium borate crystals of different cutting angles. The full-widths at half-maximum of the SHG pulses are around 150 fs, which are obtained from the cross-correlation measurement with a reverse-biased 280-nm light-emitting diode as the twophoton absorption photo-detector. Such pulses are used to perform nondegenerate pump-probe experiments on an InGaN thin film, in which indium-rich nano-clusters and compositional fluctuations have been identified. Relaxation of carriers from the pump level to the probe one through the scattering-induced local thermalization (<1 ps) and then the carrier-transport-dominating global thermalization (in several ps) processes is observed.

A new free-access collision resolution algorithm based connection request procedure for land mobile satellite systems (1989)

A novel connection request procedure for a land mobile satellite system (LMSS) is described. The procedure is based on a binary-feedback free-access collision resolution algorithm (CRA) operating over a number of parallel channels. This protocol is shown to achieve a much higher stable throughput than the previously recommended modified slotted ALOHA protocol for making connection requests. The complexity involved in implementing such a protocol is inherently low. Furthermore, this protocol is superior to other multiple-channel obvious blocked-access CRA protocols. By interleaving the time slots among individual channels, it can be applied to multiple-channel land mobile satellite type systems. Simulation results are obtained that demonstrate stable performance up to capacity. Moreover, the delay throughput characteristic is extremely flat over a wide range of traffic input rates.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Experimental Petrology and Petrogenesis of Apollo 12 Basalts (1972)

Experimental studies at 1 bar and up to 30 kbar establish the crystallization sequences for basalts 12021, 12065, 12022, 12009 and 12040. Olivine is the liquidus phase at low pressures, with minor chromium spinel and pigeonitic clinopyroxene joining the olivine at lower temperatures or accompanying the olivine in the less magnesian basalts (12021, 12065). At higher pressures, subcalcic clinopyroxene becomes the liquidus phase except in the most magnesian basalt (12040) where orthopyroxene joins the olivine and becomes the liquidus phase at pressures of 25 kbar. Integration of experimental studies with observed mineralogy of natural rocks shows conclusively that the basalt compositions studied do not lie on a plagioclase + pyroxene + spinel ± olivine cotectic nor have these rocks been derived by accumulation of olivine or pyroxene into such a low temperature cotectic liquid. The Apollo 12 basalts provide clear evidence for the genesis of olivine-rich basalts in the lunar interior. The nature of the source rock is deduced to be pyroxenite or olivine-bearing pyroxenite in which orthopyroxene is probably the major phase with lesser sub-calcic or pigeonitic clinopyroxene. The 100 Mg/(Mg + Fe) ratio of the source region in the deep lunar interior is 75–80.
The Human Element (2015)

Research on the people who deliver public services offers a useful alternative perspective in an applied field with an orientation toward organizational systems, performance, and accountability. It begins inside public organizations, treating public professionals as the subjects of research rather than objects to be controlled and manipulated. This essay reviews three new books that explore aspects of this alternative perspective, which we may call “the human element.” These books focus on the characteristics of bureaucrats, women in the public sector, and race and social equity in government. They offer insights on difficult and controversial topics and serve as important resources for scholars and practitioners in public administration.
Case Study: Using CT-Deployed Scale Removal to Enhance Production in Duri Steam Flood, Indonesia (2002)

Abstract Wells in the Duri field often have a heavy scale buildup across the gravel-pack screens and the surface production equipment. This scale, which builds from calcium carbonate (CaCO3) and organic deposits in the wellbore, causes significant production decline and premature screen failures. After conventional attempts to place acid and remove scale were unsuccessful, PT Caltex Pacific Indonesia, the Company, and Schlumberger collaborated to develop a coiled tubing conveyed scale removal and fluids placement technique for gravel-pack screen completions. This paper highlights the scaling history and causes, and the yard testing, candidate recognition process, and field execution of the new technique. Post-treatment results are presented from 39 wells, showing a field production increase of more than 90 percent. The development process included scale-removal tests using numerous CT-conveyed tools. A rotating jetting tool that is optimized by software-aided hydraulics provided the maximum cleaning efficiency. Because the jetting action cleaned the screens physically, the new tool required smaller amounts of reactive fluids (xylene and acid). Safety features included a closed-loop design of the entire test circuit to avoid fluid spillage and enable safer handling and disposal of corrosive fluids. The scale removal service, which cleans using a combination of chemical and mechanical energy, has been used in 111 wells in the Duri Steam Flood (DSF). Treatment costs are lower because less reactive fluid is needed. The inert 2% potassium chloride (KCl) brine achieves most of the cleaning action, which also optimizes the spent fluid disposal. The design of the treatment fluid also reduces the downtime required for wells to return flow to normal production. The bottom line is production gain in less time.

Cloning and expression of the mouse histamine H<sub>3</sub> receptor: evidence for multiple isoforms (2004)

The existence of mouse H3-receptor isoforms was investigated by PCR analysis and cDNA cloning. Splicing mechanisms previously reported in various species are conserved in the mouse. The retention/deletion of a fragment in the third intracellular loop of the mouse receptor leads to the existence of three isoforms designated mH(3(445)), mH(3(413)) and mH(3(397)) according to the length of their deduced amino acid sequence. PCR analysis showed that mouse H3-receptor isoforms display different expression patterns in the brain. Following expression in Cos-1 cells, [125I]iodoproxyfan binding indicated similar pharmacological profiles of the mH(3(445)), mH(3(413)) and mH(3(397)) isoforms. The pharmacological profile of the mouse H3 receptor is more similar to the rat receptor than to the human receptor, although some differences were also observed between the mouse and rat receptors. For example, the potency of thioperamide and ciproxifan is slightly higher at the mouse receptor than at the rat receptor but 40-100-fold higher than at the human receptor. In situ hybridization histochemistry showed that the distribution of H3-receptor mRNAs in the mouse brain is rather similar to that previously reported in the rat brain. However, the autoradiographic and cellular expression patterns observed in several brain areas such as the thalamus or hippocampus reveal important differences between the two species.
CPU and GPU gray scale image conversion on mobile platforms (2017)

In image processing, many algorithms are designed to operate on grayscale images. This is because of speed, memory or algorithm restrictions. Color images need to be converted to grayscale in order to apply the algorithms. Converting large color images to grayscale can be done by using either the CPU or the GPU. Even if restricted by the power consumption, mobile GPUs and CPUs have enough processing power to be viable options in the situation where no desktop equivalent is available. This paper will investigate the grayscale image conversion on mobile platforms, and compare the CPU and GPU processing in both speeds and operation complexity.

TPD‐TG‐MS Investigations of the Catalytic Conversion of Glycerol over MO<sub>x</sub>‐Al<sub>2</sub>O<sub>3</sub>‐PO<sub>4</sub> Catalysts (2010)

Abstract The catalytic performance of bifunctional catalysts, MO x ‐Al 2 O 3 ‐PO 4 , that contain acidic centers and different transition metal oxide components were evaluated in the gas‐phase dehydration of glycerol using the TPD‐TG‐MS technique and a continuous flow reactor experiment. The initial catalytic activity and selectivity to acrolein and acetol significantly depends on the acidity and the type of transition metal oxide. The higher the total acidity, the higher the acrolein selectivity in the order W > Mo > Cu > V~ Fe ~Cr > Ce. On the other hand, Mn‐, Cr‐, and Fe‐containing catalysts favor the formation of products of oxidative C‐C cleavage. TPD‐TG‐MS investigations of catalysts loaded with glycerol are useful tools for fast‐screening of initial activities of catalysts in the gas‐phase dehydration of glycerol.
A sugar‐specific porin, ScrY, is involved in sucrose uptake in enteric bacteria (1991)

During the molecular analysis of a plasmid-coded sucrose metabolic pathway of enteric bacteria, a gene, scrY, was found whose product, ScrY, had all the properties of a bacterial porin (Schmid et al., 1988). Loss of this protein (Mr 58 kDa), localized in the outer membrane, led, as shown here, to an increase in the apparent Km for sucrose transport in whole cells from 10 microM in wild-type cells to 300 microM in mutant cells. This contrasts with the Km for sucrose phosphorylation as measured in membrane vesicles from mutant and wild-type cells, which remained unchanged at about 10 microM, and reflects the activity of the sucrose-specific Enzymell of the phosphoenolpyruvate-dependent carbohydrate:phosphotransferase system (PTS) responsible for uptake through the inner membrane. Furthermore, the presence of ScrY restored growth on maltodextrins in cells devoid of LamB, thus complementing the lack of this maltoporin. The amino acid sequence deduced from the DNA sequence was determined for the plasmid-coded and the ScrY porin coded in the chromosome of Klebsiella pneumoniae. Both show high identity (86%) to each other, and to the channel domain of LamB, further corroborating the conclusion that they constitute porins.

Characterization of a non thermal plasma torch (2009)

A non thermal He plasma needle was developed and characterized. The plasma was produced using the method presented in Anghels et al., which utilizes a resonant transformer to produce the voltages necessary to breakdown the helium (He) working gas. The plasma under study was found to have an output power less than 2 watts for all flow rates used with voltages around 4.5 kV AC peak to peak. We present data referencing the plasma breakdown voltage as well as current and power measurements. The physical appearance of the plasma discharge at various flow rates was also recorded and documented. The plasma circuitry was characterized in an effort to better understand the key operating parameters of the plasma itself. Both simulation and experimentation were used to gather quantitative and qualitative data, which are presented in this paper.
