Mac-1 expression and superoxide generation of the peripheral polymorphonuclear leukocyte following gastrectomy and esophagectomy. (1995)

The aim of this study was to evaluate the characteristics of the polymorphonuclear leukocyte (PMN) function after surgical stress. We investigated Mac-1 expression and superoxide generation by peripheral PMNs and serum granulocyte-colony stimulating factor (G-CSF) concentrations in 15 patients who underwent either gastrectomy (n = 8) or esophagectomy (n = 7). The serum G-CSF rapidly increased within 24 hours after operation. The maximum levels of serum G-CSF in the cases of esophagectomy were about 5-8 fold those of gastrectomy, although the increases in PMN counts within 24 hours of esophagectomy were lower than those after gastrectomy. Mac-1 expression and superoxide generation by PMN counts and serum G-CSF. After esophagectomy, Mac-1 expression on peripheral PMNs remained elevated through the 7th day after operation, while superoxide generation by PMNs in response to PMA declined to below preoperative levels after the 3rd day. These results suggest that, after major surgery such as esophagectomy, there is a discrepancy between Mac-1 expression and superoxide generation by the peripheral PMN despite a high level of serum G-CSF.
Performance and Application of High Pressure Ratio Scroll Compressors (1995)

Abstract Scroll compressors are seldom used for high pressure ratio applications, despite their rapidly increasing inroads into relatively low pressure ratio air conditioning applications. Semi-hermetic reciprocating machines and, to a lesser extent in larger sizes, twin screw compressors dominate the high pressure ratio market. This is due, in part, to operating characteristics of scroll compressors at these conditions that seem to place scrolls at an inherent efficiency disadvantage. This paper presents an analysis of high pressure ratio scroll compressors and looks at the influences of built-in volume ratios and a dynamic discharge valve on compressor performance. The analysis includes throttling flow losses, over- and under-compression losses, and clearance volume re-expansion losses. Effects of the variable area of the discharge port opening throughout the compression cycle, valve losses (if present), and additional compressibility effects are included. The clearance volume effects, influencing only scroll compressors with dynamic discharge valves, are compared with those in reciprocating compressors. The importance of these various effects is evaluated over a range of saturated evaporator and condenser conditions. Comparison of scroll compressor efficiency with and without the discharge valve is presented over a wide range of pressure ratio conditions. The results of the study show that scroll compressors for high pressure ratio application benefit from a discharge valve. Typically, the scroll compressor with the discharge valve becomes more efficient for system pressure ratios exceeding four. Below this pressure ratio, the compressor without the discharge valve is more efficient because of the absence of discharge valve losses. However, at pressure ratios above four the use of a discharge valve becomes beneficial, because under-compression losses are eliminated. Also, the effect of the discharge port on the throttling losses is less pronounced in high pressure ratio than in low pressure ratio applications, because of reduced volume flow through the discharge port. This makes scroll compressors with a smaller discharge port acceptable for high pressure ratio applications and allows for the design of the scroll compressors with larger built-in pressure ratios and smaller clearance volumes, thus minimizing the losses specific to high pressure ratio applications.
Implementation of a CMOS/MEMS Accelerometer with ASIC Processes (2019)

This paper presents the design, simulation and mechanical characterization of a newly proposed complementary metal-oxide semiconductor (CMOS)/micro-electromechanical system (MEMS) accelerometer. The monolithic CMOS/MEMS accelerometer was fabricated using the 0.18 μm application-specific integrated circuit (ASIC)-compatible CMOS/MEMS process. An approximate analytical model for the spring design is presented. The experiments showed that the resonant frequency of the proposed tri-axis accelerometer was around 5.35 kHz for out-plane vibration. The tri-axis accelerometer had an area of 1096 μm × 1256 μm.
Blueshifting of InGaAsP/InP laser diodes by low-energy ion implantation (1997)

A new method based on low-energy implantation is presented for the fabrication of laser diodes with shifted emission wavelength. The laser diodes are based on InGaAsP/InGaAs/InP material, with compressively strained active layers. Low-energy implantation (18 keV As+) is used to generate vacancies near the surface of an incomplete laser structure, for which the epitaxial growth was interrupted 45 nm above the active layers of the device. The vacancies are subsequently diffused through the quantum wells by rapid thermal annealing. This diffusion causes a local intermixing of atoms at the interfaces of the active layers, which induces an increase of the band gap energy. The implantation/anneal process can be repeated several times to increase the amount of intermixing, thereby further shifting the emission wavelength. Once this process is completed, the upper optical confinement layer of the structure is overgrown using chemical beam epitaxy. Operational lasers with blueshifts as large as 35 nm were obtained.
Automatic Identification of Non-Meaningful Body-Movements and What It Reveals About Humans (2017)

We present a framework to identify whether a public speaker's body movements are meaningful or non-meaningful ("Mannerisms") in the context of their speeches. In a dataset of 84 public speaking videos from 28 individuals, we extract 314 unique body movement patterns (e.g. pacing, gesturing, shifting body weights, etc.). Online workers and the speakers themselves annotated the meaningfulness of the patterns. We extracted five types of features from the audio-video recordings: disfluency, prosody, body movements, facial, and lexical. We use linear classifiers to predict the annotations with AUC up to 0.82. Analysis of the classifier weights reveals that it puts larger weights on the lexical features while predicting self-annotations. Contrastingly, it puts a larger weight on prosody features while predicting audience annotations. This analysis might provide subtle hint that public speakers tend to focus more on the verbal features while evaluating self-performances. The audience, on the other hand, tends to focus more on the non-verbal aspects of the speech. The dataset and code associated with this work has been released for peer review and further analysis.

Effects of substrate heating and vacuum annealing on optical and electrical properties of alumina-doped ZnO films deposited by DC magnetron sputtering (2011)

Alumina-doped zinc oxide (AZO) films have wide range of applications in optical and optoelectronic devices. AZO films have advantage in high transparency, high stability to hydrogen plasma and low cost to alternative ITO film. AZO film was prepared by direct-current (DC) magnetron sputtering from ceramic ZnO:Al<sub>2</sub>O<sub>3</sub> target. The AZO films were compared in two different conditions. The first is substrate heating process, in which AZO film was deposited by different substrate temperature, room temperature, 150 °C and 250 °C. The second is vacuum annealing process, in which AZO film with deposited at room temperature have been annealed at 250 °C and 450 °C in vacuum. The optical properties, electrical properties, grain size and surface structure properties of the films were studied by UV-VIS-NIR spectrophotometer, Hall effect measurement equipment, x-ray diffraction, and scanning electron microscopy. The resistivity, carrier mobility, carrier concentration, and grain size of AZO films were 1.92×10<sup>-3</sup> Ω-cm, 6.38 cm<sup>2</sup>/Vs, 5.08×10<sup>20</sup> #/cm<sup>3</sup>, and 31.48 nm respectively, in vacuum annealing of 450 °C. The resistivity, carrier mobility, carrier concentration, and grain size of AZO films were 8.72×10<sup>-4</sup> Ω-cm, 6.32 cm<sup>2</sup>/Vs, 1.13×10<sup>21</sup> #/cm<sup>3</sup>, and 31.56 nm, respectively, when substrate temperature was at 250 °C. Substrate heating process is better than vacuum annealed process for AZO film deposited by DC Magnetron Sputtering.

A flood routing method for data networks (2002)

A new routing algorithm based on a flooding method is introduced. Flooding techniques have been used previously, e.g. for broadcasting the routing table in the ARPAnet and other special purpose networks. However, sending data using flooding can often saturate the network and it is usually regarded as an inefficient broadcast mechanism. Our approach is to flood a very short packet to explore an optimal route without relying on a preestablished routing table, and an efficient flood control algorithm to reduce the signalling traffic overhead. This is an inherently robust mechanism in the face of a network configuration change, it achieves automatic load sharing across alternative routes, and has the potential to solve contemporary routing problems. An version of this mechanism was originally developed for virtual circuit establishment in the experimental Caroline ATM LAN at Monash University.
ADP-ribosylation Factor 1 Controls the Activation of the Phosphatidylinositol 3-Kinase Pathway to Regulate Epidermal Growth Factor-dependent Growth and Migration of Breast Cancer Cells (2008)

Activation of intracellular signaling pathways by growth factors is one of the major causes of cancer development and progression. Recent studies have demonstrated that monomeric G proteins of the Ras family are key regulators of cell proliferation, migration, and invasion. Using an invasive breast cancer cell lines, we demonstrate that the ADP-ribosylation factor 1 (ARF1), a small GTPase classically associated with the Golgi, is an important regulator of the biological effects induced by epidermal growth factor. Here, we show that this ARF isoform is activated following epidermal growth factor stimulation and that, in MDA-MB-231 cells, ARF1 is found in dynamic plasma membrane ruffles. Inhibition of endogenous ARF1 expression results in the inhibition of breast cancer cell migration and proliferation. The underlying mechanism involves the activation of the phosphatidylinositol 3-kinase pathway. Our data demonstrate that depletion of ARF1 markedly impairs the recruitment of the phosphatidylinositol 3-kinase catalytic subunit (p110alpha) to the plasma membrane, and the association of the regulatory subunit (p85alpha) to the activated receptor. These results uncover a novel molecular mechanism by which ARF1 regulates breast cancer cell growth and invasion during cancer progression.
Cloning and characterisation of mtDBP, a DNA-binding protein which binds two distinct regions of sea urchin mitochondrial DNA (1999)

The cDNA for the sea urchin mitochondrial D-loop-binding protein (mtDBP), a 40 kDa protein which binds two homologous regions of mitochondrial DNA (the D-loop region and the boundary between the oppositely transcribed ND5 and ND6 genes), has been cloned. Four different 3'-untranslated regions have been detected that are related to each other in pairs and do not contain the canonical polyadenylation signal. The in vitro synthesised mature protein (348 amino acids), deprived of the putative signal sequence, binds specifically to its DNA target sequence and produces a DNase I footprint identical to that given by the natural protein. mtDBP contains two leucine zippers, one of which is bipartite, and two small N- and C-terminal basic domains. A deletion mutation analysis of the recombinant protein has shown that the N-terminal region and the two leucine zippers are necessary for the binding. Furthermore, evidence was provided that mtDBP binds DNA as a monomer. This rules out a dimerization role for the leucine zippers and rather suggests that intramolecular interactions between leucine zippers take place. A database search has revealed as the most significative homology a match with the human mitochondrial transcription termination factor (mTERF), a protein that also binds DNA as a monomer and contains three leucine zippers forming intramolecular interactions. These similarities, and the observation that mtDBP-binding sites contain the 3'-ends of mtRNAs coded by opposite strands and the 3'-end of the D-loop structure, point to a dual function of the protein in modulating sea urchin mitochondrial DNA transcription and replication.
A Low-Cost Solar-Cell Front Contact Using Trapped Silver Mesh and Electrostatic Bonding (1979)

One of the major costs of modern solar-cell manufacture is that of applying a metallized contact grid to the cell front surface. If solar energy is to become a viable source of !ow-cost electricity, this expense must be reduced significantly. To keep efficiency high, a metallization grid must provide narrow closely spaced high conductivity lines. A new system to provide this contact with a silver mesh trapped between the cell and an encapsulating glass cover has been demonstrated. Borosilicate glass is permanently joined to the cell by electrostatic bonding, an adhesive-free field-assisted glass-metal sealing technique. During this process the glass is deformed around the silver mesh to form a permanent optically coupled integral bond to the cell. This hermetic seal prevents the silver from oxidizing and destroying the electrical contact formed during the bonding process. Cells produced this way have been demonstrated with curve fill factors of 0.69. A thin titanium layer evaporated on the mesh seems to improve the results. Specific contact resistance measured for this system is on the order of 20-30 m <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">\Omega</tex> -cm <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> .

A Sentence Similarity Estimation Method Based on Improved Siamese Network (2018)

In this paper we employ an improved Siamese neural network to assess the semantic similarity between sentences. Our model implements the function of inputting two sentences to obtain the similarity score. We design our model based on the Siamese network using deep Long Short-Term Memory (LSTM) Network. And we add the special attention mechanism to let the model give different words different attention while modeling sentences. The fully-connected layer is proposed to measure the complex sentence representations. Our results show that the accuracy is better than the baseline in 2016. Furthermore, it is showed that the model has the ability to model the sequence order, distribute reasonable attention and extract meanings of a sentence in different dimensions.
Synthesis and secretion of an atriopeptin-like protein in rat kidney cell culture. (1991)

The synthesis and secretion of an atriopeptin(AP)-like prohormone (AP126ir) has been demonstrated in rat neonatal renal cell cultures. AP126ir could be detected in the cellular extract and the medium from cultured kidney cells of neonatal and adult rats using an enzyme immunoassay specific for cardiac AP prohormone. On reverse-phase high-performance liquid chromatography, the AP obtained from the extract and the medium comigrated with cardiac AP prohormone. Incubation of the renal AP in the medium with thrombin resulted in the generation of a single low molecular mass peak which migrated with the cardiac carboxy-terminal 28-amino acid AP. Neonatal kidney cells pulsed with [35S]methionine secreted radiolabeled AP126ir, which was detected by immunoprecipitation and sodium dodecyl sulfate-polyacrylamide gel electrophoresis chromatography. Incubation of neonatal kidney cell cultures with the protein synthesis inhibitor cycloheximide resulted in a significant decrease in both the cellular and media AP. No decrease in cellular and media AP was detected when neonatal atrial cultures were treated with cycloheximide. These data demonstrate the de novo synthesis of an AP prohormone-like protein in neonatal rat kidney cultures. Furthermore, unlike the atria, kidney cells appear to secrete AP solely by constitutive means. In primary adult rat kidney cultures, most of AP126ir was detected in the cortical tubule fraction demonstrating that these cells secrete AP126ir in the adult rat kidney. We hypothesize that the renal AP may be important as an autocrine or paracrine regulator of renal function.
Hardware support for control transfers in code caches (2003)

Many dynamic optimization and/or binary translation systems hold optimize/translated superblocks in a code cache. Conventional code caching systems suffer from overheads when control is transferred form one cached superblock to another, especially via register-indirect jumps. The basic problem is that instruction addresses in the code cache are different from those in the original program binary. Therefore, performance for register-indirect jumps depends on the ability to translate efficiently from source binary PC values to code cache PC values. We analyze several key aspects of superblock chaining and find that a conventional baseline code cache with software jump target prediction results in 14.6% IPC loss versus the original binary. We identify the inability to use a conventional return address stack as the most significant performance limiter in code cache systems. We introduce a modified software prediction technique that reduces the IPC loss to 11.4%. This technique is based on a technique used in threaded code interpreters. A number of hardware mechanisms, including a specialized return address stack and a hardware cache for translated jump target addresses, are studied for efficiently supporting register-indirect jumps. Once all the chaining overheads are removed by these support mechanisms, a superblock-based code cache improves performance due to a better branch prediction rate, improved I-cache locality, and increased chances of straight-line fetches. Simulation results show a 7.7% IPC improvement over a current generation 4-way superscalar processor.

Development and assessment of a powered 3D-printed prosthetic hand for transmetacarpal amputees (2017)

New proposals for prosthetic hands fabricated by means of 3D printing are either body-powered for partial hand amputees or myoelectric powered prostheses for transradial amputees. There are no current studies to develop powered 3D printed prostheses for transmetacarpal, probably because at this level of amputation there is little space to fit actuators and their associated electronics. In this work, a design of a 3D-printed hand prosthesis for transmetacarpal amputees and powered by DC micromotors is presented. Four-bar linkage mechanisms were used for the index, middle, ring and little fingers flexion movements, while a mechanism of cylindrical gears and worm drive were used for the thumb. Additionally, a method for customizing prosthetic fingers to match a user specific anthropometry is proposed. Sensors and actuators' selection is explained, and a position control algorithm was developed for each local controller by modeling the DC motors and transmission mechanisms. Finally, a basic control scheme was tested on the prototype for velocity and force evaluation.
Traceurs fluorescents à base de lanthanides en milieu complexe (2014)

Tracers are objects allowing the determination of the position or the distribution of a product; tracers are currently used in a great variety of domains. Despite the fact that each field has it's own specifications, it is possible to find tracers in medicine (contrast agents), anti-counterfeiting or geological exploration. We have developed lanthanide complex tracers for oil field injection waters. Those tracers, derived from the DOTA, have been detected at concentration lower than 1 ppb, thanks to a simple and compact apparatus. This detection has been made possible by the use of time-resolved fluorescence spectroscopy, this technique allows us to get rid of the background noise created by the intrinsic fluorescence of oil residues that are present in production waters. We also demonstrated how we can, through a reverse microemulsion synthesis, encapsulate several different dyes inside a single nanoparticle composed of a gold core and a silica shell. We showed as well, how those particles can be used as smart tracers to gather data, such as temperature, pH, solvents, etc. inside the well. Finally the use of lanthanides and scale inhibitors properties allowed us to create a simple and fast dosing protocol of such scale inhibitors in injection waters. This dosage will then allow the quick adjustment of their concentration inside each well
