Natural history of hepatopulmonary syndrome (2005)

Few data exist concerning survival after the diagnosis of hepatopulmonary syndrome (HPS). Although orthotopic liver transplantation (OLT) frequently results in complete resolution of HPS, the relationship between transplantation and survival has not been described. The study rationale was to describe long-term survival in patients with HPS. Data were derived from patients diagnosed with HPS at Mayo Clinic (n = 61) between 1985 and 2002, including those undergoing OLT (n = 24) and those who did not (n = 37). A case-control, Kaplan-Meier survival analysis between HPS patients and 77 patients without HPS matched for liver disease cause, model for end-stage liver disease (MELD), severity of liver disease by the Child classification, and age was described for OLT and non-OLT groups. Patients with HPS had a mean partial pressure of arterial oxygen (PaO(2)) decline of 5.2 + 2.3 mm Hg per year awaiting OLT. For HPS patients, despite similar baseline PaO(2), brain uptake of technetium macroaggregated albumin ((99m)TcMAA), or measures of hepatic dysfunction, 5-year survival associated with OLT was 76% versus 23% who did not undergo transplantation (P < .0001). Comparing those who did not undergo transplantation, HPS patients had worse 5-year survival than matched controls (P = .0003). However, reasons to deny OLT (comorbidity) in the setting of HPS may well have contributed to observed survival differences. Baseline PaO(2) </=50 mm Hg was associated with worse survival irrespective of the decision to perform OLT. In conclusion, hypoxemia of HPS is frequently progressive. As OLT outcome relates to pretransplantation PaO(2), additional MELD points should advance the priority for OLT in HPS.
Organizational and Activational Effects of Testosterone on Masculinization of Female Physiological and Behavioral Stress Responses (2008)

The prevalence of affective disorders is two times greater in women than in men. The onset of anxiety and depression occurs at different ages that may correspond to key developmental periods when the brain is more vulnerable to hormonal and exogenous influences. Because stressful life events can precipitate disease onset, the development of greater stress sensitivity in females may contribute to their increased vulnerability. Gonadal hormone exposure in males during early development and again from puberty onward plays a prominent role in sexually dimorphic brain formation, possibly contributing to sex differences in stress responsivity. Therefore, organizational effects of testosterone propionate (TP) administered postnatally and activational effects of TP administered beginning at puberty on adult female physiological and behavioral stress responses were examined in mice. Although the activational effects of TP in females ameliorated the sex difference in the hypothalamic-pituitary-adrenal axis stress response, there was no effect of postnatal TP. Similarly, higher immobile time in intact females in the tail suspension test was blunted by activational TP in the absence of postnatal TP. However, in the marble-burying test of anxiety-like behaviors, organizational and activational TP independently resulted in increased burying behaviors. These results show that TP administration has distinct effects on reducing physiological and behavioral stress responsivity in rodent models and suggest that sex differences in these responses may partially result from the absence of testosterone in females.

Effect and mechanism of some new voltage stabilizers for cross-linked polyethylene insulation (1974)

The courageous acceptance of cross-linked polyethylene (XLPE) cables for power transmission and distribution during the past decade results from significant advances in manufacturing technology and quality. Successful service stimulates cable engineers to extend XLPE cable toward higher power capability through higher operating voltages. In recent years two practical and technological approaches have been developed for XLPE power cable; one is the development of a new type of manufacturing process, <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sup> the other is the incorporation of a certain additive (voltage stabilizer) into solid insulation. This additive helps in the prevention or suppression of premature failure or cumulative deterioration, leading to insulation puncture.
Protein Engineering with Nonstandard Amino Acids (2003)

Site-directed mutagenesis has become an extremely powerful tool for the study of protein folding, protein-protein interactions, enzymatic catalysis, and other structure-function issues. Whereas this technique has had a major impact, it nonetheless has been limited to the 20 “proteinogenic” (standard) amino acids normally incorporated during ribosomal biosynthesis. This limitation has precluded the ability to site-specifically incorporate other amino acids that have been specifically designed to probe structure, function, or activity in novel ways. The ability to modify a protein by site-specifically introducing such non-standard amino acids with novel functionality would thus be useful in many investigations, but in addition, the ability to introduce nonstandard amino acids with more conservative modifications than are allowed by traditional site-directed mutagenesis (i.e., substitution of a single atom within an amino acid side chain) also could be quite useful.
The Electrochemistry of the FPL (Forest Products Laboratory) Process and its Relationship to the Durability of Structural Adhesive Bonds (1992)

Abstract The FPL (Forest Products Laboratories) Process for preparing aluminum for structural adhesive bonding has been used in the aerospace industry since the early 1950's. Problems were encountered with the use of the process when the industry changed from phenolic to epoxy adhesives. In-service disbonds followed by corrosion were observed. This review article describes an investigation of the electrochemistry of the FPL etch process. Through a combination of electrochemical polarization measurements, surface chemical and surface morphological investigations and a thorough application of the Boeing wedge test, we are able to provide a mechanism of action of the FPL etch process. An oscillating electrochemical reaction was observed for low alloy aluminum which was ascribed to the dissolution and redeposition of copper on the aluminum during the etching process. A spatial variation in wedge test performance was found in that edge specimens demonstrated lower crack extensions than center specimens when using a low alloy aluminum that was etched in an FPL etch bath that was low in copper. These results are positioned in a historical perspective providing some insight into possible reasons for the irreproducibility of durability of structural adhesive bonds made with low alloy aluminum adherends that were prepared in a low copper content FPL etch bath.
Characterization of six partial deletions in the low-density-lipoprotein (LDL) receptor gene causing familial hypercholesterolemia (FH). (1988)

Two hundred thirty-four unrelated heterozygotes for familial hypercholesterolemia (FH) were screened to detect major rearrangements in the low-density-lipoprotein (LDL) receptor gene. Total genomic DNA was analyzed by Southern blot hybridization to probes encompassing exons 1-18 of the LDL receptor gene. Six different mutations were detected and characterized by the use of exon-specific probes and detailed restriction mapping. Each mutation is unique and suggests that molecular heterogeneity underlies the molecular pathology of FH. There appear to be preferential sites within the LDL receptor gene for major rearrangements resulting in deletions.
Towards detection of human motion (2002)

Detecting humans in images is a useful application of computer vision. Loose and textured clothing, occlusion and scene clutter make it a difficult problem because bottom-up segmentation and grouping do not always work. We address the problem of detecting humans from their motion pattern in monocular image sequences; extraneous motions and occlusion may be present. We assume that we may not rely on segmentation or grouping and that the vision front-end is limited to observing the motion of key points and textured patches in between pairs of frames. We do not assume that we are able to track features for more than two frames. Our method is based on learning an approximate probabilistic model of the joint position and velocity of different body features. Detection is performed by hypothesis testing on the maximum a posteriori estimate of the pose and motion of the body. Our experiments on a dozen of walking sequences indicate that our algorithm is accurate and efficient.
Characterization of a stable form of human meizothrombin derived from recombinant prothrombin (R155A, R271A, and R284A) (1994)

Meizothrombin is a transient intermediate produced during the activation of prothrombin by the prothrombinase complex. Because meizothrombin is very sensitive to further activation and autolysis, its isolation is possible only in the presence of active site thrombin inhibitors. This complicates studies of the activities and functions of meizothrombin. As a model, we have expressed a mutant human prothrombin cDNA (R155A, R271A, R284A) with three of the cleavage sites modified so that they are no longer cleaved by factor Xa or thrombin. Several stable baby hamster kidney cell lines were isolated that secreted up to 20 micrograms/ml of carboxylated mutant prothrombin. After purification, the mutant prothrombin was activated by the prothrombinase complex or by ecarin, resulting in the formation of a meizothrombin-like molecule. Electrophoretic analysis and NH2-terminal sequence analysis were consistent with cleavage of a single bond between Arg320-Ile321 and proper processing of the prepropeptide. The meizothrombin was stable for weeks at 4 degrees C. Activation in the presence of dansylarginine N-(3-ethyl-1,5-pentanediyl) amide confirmed the conversion of prothrombin via meizothrombin. Compared with human plasma-derived thrombin, recombinant meizothrombin demonstrated approximately 7% clotting activity, 100% p-toluene-sulfonylarginine methyl ester esterase activity, and approximately 35% S2238 amidolytic activity, and could attenuate fibrinolysis.
General outdoor air economizer fault detection and diagnostics assessment method. (2012)

Outdoor air economizers (OAE) control the amount of air drawn into a building in order to reduce energy usage and improve indoor air quality. Air-side economizers are required by energy standards such as ASHRAE Standard 90.1 in many commercial applications because of their energy savings’ potential. However, many economizers do not operate as designed because of damper, sensor, and other faults which can actually lead to greater energy use. Fault detection and diagnostics (FDD) tools have been developed to identify faults when they occur, however, no general methodology for assessing these tools has yet to be proposed. This paper presents and applies a general OAE FDD assessment method. FDD tools described by Seem and House (2009), Schein et al. (2003), and Brambley et al. (1998) are analyzed with respect to various OAE faults. Additionally, these FDD methods are assessed with the method using simulated and experimental data with both single and multiple simultaneous faults.
Adenovirus Type 5 E4 Open Reading Frame 4 Protein Induces Apoptosis in Transformed Cells (1998)

Adenovirus type 5 E4 open reading frame 4 (E4orf4) protein has been previously shown to counteract transactivation of the junB and c-fos genes by cyclic AMP plus E1A protein and to interact with protein phosphatase 2A (PP2A). Here, we show that the wild-type E4orf4 protein induces apoptosis in the E1A-expressing 293 cells, in NIH 3T3 cells transformed with v-Ras, and in the lung carcinoma cell line H1299. The induction of apoptosis is not accompanied by enhanced levels of p53 in 293 cells and occurs in the absence of p53 in H1299 cells, indicating involvement of a p53-independent pathway. A mutant E4orf4 protein that had lost the ability to induce apoptosis also lost its ability to bind PP2A. We suggest that E4orf4 antagonizes continuous signals to proliferate, like those given by E1A or v-Ras, and that the conflicting signals lead to the induction of cell death.
Fiber-optic refractometer based on a phase-shifted fiber Bragg grating on a side-hole fiber (2015)

A fiber-optic refractive index (RI) sensor based on a π-phase-shifted fiber-Bragg-grating (πFBG) inscribed on a side-hole fiber is presented. The reflection spectrum of the πFBG features two narrow notches associated with the two polarization modes and the spectral spacing of the notches is used for high-sensitivity RI sensing with little temperature cross-sensitivity. The side-hole fiber maintains its outer diameter and mechanical strength. The side-hole fiber is also naturally integrated into a microfluidic system for convenient sample delivery and reduced sample amount. A novel demodulation method based on laser frequency modulation to enhance the sensor dynamic range is proposed and demonstrated.

Phonetically guided clustering for isolated word recognition (2005)

A variant of the Markov source modelling of entire words based on automatically determined subword units is described. Each word of the vocabulary is modelled as a linear sequence of phoneme segments given by a phonetic transcription. For every phoneme a minimum and maximum duration are to be specified. Matching an utterance to the models must be performed within these absolute durational constraints. This is achieved by a dynamic programming time alignment different from the conventional ones. The acoustic emission is defined by means of phonetically labelled prototype vectors. The parameters of the models are automatically trained by an iterative procedure similar to the Viterbi algorithm. The method is applied to speaker-dependent and independent recognition of the German digits (telephone speech).
Perflourosulfonyl imides and methides: investigating the lithographic potential of novel superacid PAGs (2002)

The lithographic performance of a new class of onium type photo acid generators (PAGs) developed by 3M Company has been evaluated using standard hybrid/acetal and ESCAP type DUV (248 nm) photoresist formulations. The new PAGs produce perfluoroalkyl sulfonylimides or sulfonylmethides with superacidic properties matching or exceeding the acid strength of commonly known perfluoroalkyl sulfonic acids, such as trifluoromethane sulfonic acid. The direct comparison of near commercial photoresist formulations containing onium perfluoroalkyl sulfonates with identical materials using equimolar amounts of the new PAGs revealed that the new 3M PAGs give rise to almost identical lithographic properties, such as resolution, DOF, and exposure latitude. In addition, secondary properties such as photoresist stability, delay stability, or line edge roughness are almost equivalent, and thus the new PAGs are considered as suitable candidates used for the manufacturing of high volume production photoresists.

Transformation of<i>Staphylococcus epidermidis</i>and other staphylococcal species with plasmid DNA by electroporation (1990)

In this paper, the influence of various parameters on plasmid tranformation by electroporation of Staphylococcus epidermidis Tü3298 was investigated. Cell growth conditions, various concentrations and forms of plasmid DNA, field strength, pulse duration and media for electroporation and regeneration were tested. In order to obtain optimal transformation efficiency, the cells were incubated for 30 min with DNA before pulsing. With the optimized procedure, other staphylococcal species such as S. aureus, S. staphylolyticus and S. carnosus were transformed with an efficiency up to 3× 105 transformants per μg pC194 plasmid DNA.

A belief propagation based recommender system for online services (2010)

In this paper we report our progress in the first application of iterative probabilistic algorithms in the design and evaluation of recommender systems. The proposed iterative recommender system (referred to as BPRS) is based on the belief propagation, a powerful decoding algorithm for turbo codes and Low-Density Parity-Check (LDPC) codes. The belief propagation algorithm relies on a graph-based representation of an appropriately chosen factor graph for the recommender systems. The factor graph representation of the recommender systems turned out to be a bipartite graph, where the users and products are arranged as two sets of variable and factor nodes that are connected via some edges. Recommendations (predicted ratings) for each particular user can be computed by probabilistic message passing between nodes in the graph. We provide an evaluation of BPRS via computer simulations using the MovieLens dataset. We observed that BPRS iteratively reduces the error in the predicted ratings of the users until it converges. Further, our initial results indicate an improvement in the Mean Average Error (MAE) and Root Mean Square Error (RMSE) over the Item Averaging. Therefore, we are confident that the belief propagation is a new promising approach which will offer robustness and accuracy for the recommender systems.
A novel method for crosslinking polyetheretherketone (1988)

Abstract A novel method for crosslinking polyetheretherketone via imine formation at carbonyl groups is presented. In polyetheretherketone these Schiff bases form short, stiff crosslink junctions which are stable up to 630°C. Dynamic mechanical and thermal properties of polyetheretherketone and imine crosslinked polyetheretherketone are reviewed. A large reduction in the temperature sensitivity of the material stiffness has been achieved. Increases in the glass transition temperature from 143°C to greater than 280°C have been obtained.

Weight Loss Outcomes in Laparoscopic Vertical Sleeve Gastrectomy (LVSG) Versus Laparoscopic Roux-en-Y Gastric Bypass (LRYGB) Procedures: A Meta-Analysis and Systematic Review of Randomized Controlled Trials (2017)

In conclusion, LRYGB and LVSG are comparable with regards to the weight loss outcomes in the short term, with LRYGB achieving slightly greater weight loss. Slow weight recidivism is observed after the first postoperative year following both procedures. Long-term reporting of outcomes obtained from well-designed studies using intention-to-treat analyses are identified as a major gap in the literature at present.
