A Ubiquitous Homecare Service System Using a Wearable User Interface Device (2012)

This paper presents design and implementation of a homecare system that provides home control assistance and fall detection services using a wrist-watch type wireless motion and location sensing device. This user interface device is equipped with a Zigbee radio transceiver to communicate with a home gateway and track location of the user. The user interface device is also equipped with a 3-axis accelerometer to measure user's 3D motion data so that the home gateway can recognize the user's behavior and fall status.
Defining International Electronic Commerce (1992)

Electronic commerce has become a practical reality for thousands of businesses throughout the world. By combining the functional capabilities of computers and telecommunication systems, companies can now exchange information electronically rather than sending and receiving paper documents. In so doing, businesses are achieving remarkable and unparalleled improvements in the accuracy, speed and efficiency with which commercial transactions may be negotiated, confirmed and performed. By eliminating reliance upon paper as the medium through which commerce occurs, new and radically different approaches are emerging regarding how commercial relationships are defined and maintained. Used for international business transactions, the technologies of electronic commerce are confronting and overcoming traditional barriers to international trade presented by geographic, lingual and cultural disparities between possible trading partners. As a result, facilitating international electronic commerce throughout the global trading community is now fairly considered a project of the highest priority on the international agenda.
Video-scanning system for measurement of lip and jaw motion (1977)

An instrument for measuring labial and mandibular positions during speech is described. A modified video system is used to measure the positions of small reflecting glass beads attached at selected points on the face and to a thin wire anchored on a mandibular tooth. The system allows continuous data collection from up to 16 reflector points at a sampling rate of 100 Hz. Reflector movements with instantaneous velocities up to 45 cm/sec can be determined with a 0.3-mm resolution. Techniques for data acquisition and analysis and display are described.
Direct determination of surface tension in the lung. (1976)

We have used the spreading behavior of small drops of several fluorocarbon fluids and silicone oil on air-liquid interfaces to measure the surface tension of lungs in situ. The test fluids were calibrated in a surface balance at 37 degrees on monolayers of dipalmitoylphosphatidylcholine. At particular surface tensions characteristic of each fluid used, an increase in the tension of 1 mN/m or less caused the droplets to spread reversibly from a sphere to a lens shape. Using micropipettes we placed such droplets on the alveolar surfaces of excised rat lungs held at functional residual capacity and 37 degrees and found that the surface tension remained below 9 mN/m for at least 30 min. The surface tension-volume relationship was linear for tensions ranging from 9 to 20 mN/m.
Expression of SRY transcripts in preimplantation human embryos (1995)

We have examined the expression of SRY mRNA in individual in vitro fertilized preimplantation human embryos; because of ethical constraints, these studies were confined to embryos with one and three pronuclei. Using a sensitive reverse transcriptase-polymerase chain reaction (RT-PCR) assay, we observed SRY mRNA at the one-cell through the blastula stages but not in spermatozoa. These results indicate that the de novo transcription of this sex-specific gene occurs at a developmental time considerably earlier than that of gonadal differentiation. Our results also indicate that in vitro fertilized embryos with one pronucleus are likely to be diploid.
Predicting Zillow Estimation Error Using Linear Regression and Gradient Boosting (2017)

Owning property is one of the most important investments that a person can make in their lifetime. Therefore, being able to accurately know the real-time value of any property is crucial for making wise sales and purchases. Since the online real estate database company Zillow first developed a machine learning system to predict property sale prices in real time, it has continually worked to improve the accuracy of this prediction mechanism.In this paper, we describe our work to decrease the error of Zillow's price estimation by examining the effectiveness of several machine learning models and techniques at making property related forecasts. Specifically, we used property data to train linear regression and gradient boosting models with which we then made predictions about other properties. For the gradient boosting model, we used grid search to fine-tune the model's hyperparameters and observed the contribution of such tuning to the model's accuracy. Finally, we examined the effectiveness of several data preprocessing techniques, including the novel approach of treating time as a property feature.

Evaluation of metal-mediated DNA binding of benzoxazole ligands by electrospray ionization mass spectrometry (2007)

The binding of a series of benzoxazole analogs with different amide- and ester-linked side chains to duplex DNA in the absence and presence of divalent metal cations is examined. All ligands were found to form complexes with Ni2+, Cu2+, and Zn2+, with 2:1 ligand/metal cation binding stoichiometries dominating for ligands containing shorter side chains (2, 6, 7, and 8), while 1:1 complexes were the most abundant for ligands with long side chains (9, 10, and 11). Ligand binding with duplex DNA in the absence of metal cations was assessed, and the long side-chain ligands were found to form low abundance complexes with 1:1 ligand/DNA binding stoichiometries. The ligands with the shorter side chains only formed DNA complexes in the presence of metal cations, most notably for 7 and 8 binding to DNA in the presence of Cu2+. The binding of long side-chain ligands was enhanced by Cu2+ and to a lesser degree by Ni2+ and Zn2+. The cytotoxicities of all of the ligands against the A549 lung cancer and MCF7 breast cancer cell lines were also examined. The ligands exhibiting the most dramatic metal-enhanced DNA binding also demonstrated the greatest cytotoxic activity. Both 7 and 8 were found to be the most cytotoxic against the A549 lung cancer cell line and 8 demonstrated moderate cytotoxicity against MCF7 breast cancer cells. Metal ions also enhanced the DNA binding of the ligands with the long side chains, especially for 9, which also exhibited the highest level of cytotoxicity of the long side-chain compounds.
The Automated Prediction of Hearing Thresholds in Sleeping Subjects Using Auditory Steady-State Evoked Potentials (1995)

The results suggest the SSEP technique can be used as a predictor of behavioral threshold in adults and children at the frequencies 250-4000 Hz.
Characterization, solution properties, and morphologies of a hydrophobically associating cationic terpolymer (2007)

Abstract The acrylamide‐based terpolymers (PADB) with 4‐butylstyrene (BST) as the hydrophobic monomer and dimethyldiallyammonium chloride (DMDAAC) were synthesized by the micellar free radical technique. The polymer was determined by UV, FT‐IR and 1 HNMR, and the hydrophobic microblock structure of PADB was characterized successfully by the conventional DSC measurement. The use of DMDAAC improves the water solubility and intermolecular association of terpolymers. The feed amount of BST affects greatly the apparent viscosity of PADB solution. The polymer exhibits good viscosification property, salt resistance, temperature‐thickening, thixotropy, pseudoplastic behavior and shear‐thickening at low shear rate. The apparent viscosities of PADB solution remarkably increase by the addition of a small amount of surfactant. AFM measurements show that hydrophobic aggregates have been formed in 0.1 g dL −1 PADB aqueous solution, indicative of strong associations of hydrophobic groups, which are reinforced with increasing PADB concentration. The microstructures of PADB are disrupted by the addition of small amounts of salt, resulting in the decrease in solution viscosity. However, with increasing NaCl concentration, the tree‐like associating structures are formed, leading to the increase in the solution viscosity of PADB. The AFM results reveal that the solution properties of PADB are due to the associating structures in the aqueous solution and brine solution. © 2007 Wiley Periodicals, Inc.

Alternative ribosomal initiation gives rise to chicken brain-type creatine kinase isoproteins with heterogeneous amino termini. (1990)

In higher eukaryotes three different types of creatine kinases (CK) are expressed: the muscle-specific M-CK, the ubiquitous cytoplasmic B-CKs, and the mitochondrial Mi-CKs. They fulfill multiple tasks in cells with an intensive energy metabolism. Isolated chicken B-CK can be resolved by two-dimensional gel electrophoresis into a major acidic Ba-CK and a major basic Bb-CK protein species which are very likely produced from the unique chicken B-CK gene (Wirz, T., Hossle, J. P., Soldati, T., and Perriard, J.-C. (1989) Experientia (Basel) 45, 32 (abstr.]. However, close inspection of the gels indicates the presence of additional B-CK species. This additional heterogeneity is generated by two distinct post-transcriptional processes. Post-translational phosphorylation was shown to contribute to heterogeneity of both Ba- and Bb-CK isoproteins and appears to modulate their enzymatic activity (A. F. Q. Quest, H. M. Eppenberger, and T. Wallimann, manuscript in preparation). Alternative ribosomal initiation of Bb-CK synthesis at multiple sites was shown to occur in cell free systems as well as in vivo, resulting in proteins differing in the length of their amino termini. Using site-directed mutagenesis to "switch off" each of the first four methionine codons of a full length Bb-CK cDNA, we were able to correlate each protein product with one distinct translational start site. An additional protein species appears to be produced by initiation at a noncanonical start codon. We propose that a leucine codon may be used as a translational start site. Evidence is presented to support the role of these amino-terminal truncated subunits in the regulation of the enzyme.
Discrimination of pentobarbital doses and drug mixtures under fixed-ratio and fixed-interval reinforcement schedules (2001)

Pigeons were trained to discriminate among 5 mg/kg pentobarbital, 10mg/kg pentobarbital, and saline, under either fixed-interval (FI) or fixed-ratio (FR) reinforcement schedules. When baseline responding stabilized, a higher percentage of responses occurred on the key that produced the reinforcer under the FR schedule than under the FI schedule. After low doses of pentobarbital, responding shifted from the saline key to the 5 mg/kg pentobarbital key; at higher doses of pentobarbital responding shifted to the 10mg/kg pentobarbital key under both schedules. After low doses of ethanol and chlordiazepoxide, responding shifted from the saline key to the 5 mg/kg pentobarbital key, but after high doses of these drugs, responding continued to occur on the 5 mg/kg pentobarbital key under both reinforcement schedules. A 5 mg/kg dose of pentobarbital increased responding on the 10 mg/kg pentobarbital key when it was combined with pentobarbital, ethanol or chlordiazepoxide. Phencyclidine and D-amphetamine produced responding largely on the saline key under both reinforcement schedules. Under the FR schedule, pentobarbital dose-response curves were usually quantal, whereas under the FI schedule the pentobarbital dose-response curves usually were graded.
Application of Transfer Matrix Method in Acoustics (2010)

This paper shows the application of the Transfer Matrix Method in the Acoustics Module of COMSOL Multiphysics. The ana- lyzed system is the combustion chamber of an industrial gas turbine and in the 3D acoustic simulation the burners are geometrically cut and substituted by transfer matrices. The ap- plication of this methodology allows us to take into account parameters which can not be con- sidered in the Acoustics module (e.g. mean ow and viscosity) and to reduce the compu- tational eort. The Transfer Matrix method is used when the whole system can be represented into a se- quence of subsystems that interact only with adjacent subsystems. This method is fre- quently used in mathematics and, particularly, in acoustics. The application of the present method is really useful, because it permits to break the total system into a network of sub- systems, linked together by transfer matrices. These matrices can be obtained analytically, experimentally or numerically. The great im- portance of this method is the possibility of using data from experiments or from detailed numerical simulations inside the transfer ma- trix.
[Stimulation of corneal endothelial cell proliferation by interleukins, complete mitogens and corneal parenchymal cell-derived factors]. (1996)

The effects of various cytokines and mitogens on proliferation of rabbit corneal endothelial cells were examined in a serum-free culture. Complete mitogens such as epidermal growth factor (EGF), transforming growth factor alpha (TGF-alpha), and hepatocyte growth factor (HGF) stimulated proliferation of corneal endothelial cells 1.5 to 2 times the control. The effect was dose-dependent up to 10 ng/ml and flattened out at higher concentrations. Interleukins (IL-x) such as IL-1 alpha, IL-1 beta, IL-2, IL-3 or IL-4 by themselves had little or no stimulatory effect on cell proliferation. The combination of IL-1 beta and EGF, or IL-1 beta and TGF-alpha, however, showed a 5- to 6-fold stimulation over the control. IL-1 beta, thus, can be regarded as a co-mitogen that can amplify the stimulatory effect of complete mitogens (EGF and TGF-alpha). The number of corneal endothelial cells increased to 200% when corneal endothelial cells were co-cultured with corneal parenchymal cells. Addition of conditioned medium obtained from the culture of corneal parenchymal cells also increased the number of corneal endothelial cells more than 2-fold. These results suggest that factors which stimulate cell proliferation of corneal endothelial cells are secreted by corneal parenchymal cells.
Testbed evaluations of a controlled-delivery power grid (2014)

We present two testbeds and experimental evaluations of the controlled-delivery power (CDP) grid. In the CDP grid, energy is addressable and the amount of power is allocated to users in real time. The energy supplier grants the amount of energy supplied to a user and at the same time, ensures that the total supplied energy is within a fixed cap. Energy amounts are discretized to minimize management complexity and optimized for digital control. One of our testbeds mimics the present grid and the other emulates a grid provisioned with energy storage. In the presented experiments, users request and receive grants through power access points implemented with low-cost computers. The management and control plane of a supplier was implemented with a workstation, and users and supplier communicated through a data network. Alternating current (AC) at 120 V power lines were controlled by the server and delivered power to the access points. The supplier was able to maintain a high satisfaction ratio in terms of requests granted and energy delivered under limited capacity conditions.
Mapping strategies for switch-based cluster systems of irregular topology (2002)

Mapping virtual process topology to physical processor topology is one of the most important issues in parallel computing. The mapping problem for switch-based cluster systems of irregular topology is very complicated due to the connection irregularity and routing complexity. This paper proposes two mapping schemes for irregular cluster systems, which try to map the nearest neighbors in the process topology to physically adjacent processors. In addition, an application-oriented performance metric, weighted cardinality, is introduced to represent the quality of mapping. A simulation study shows that, for a virtual topology of a 16/spl times/16 mesh, the proposed mapping schemes result in better mapping quality and about 15/spl sim/20% shorter communication latency compared to random mapping. The proposed algorithms should also be beneficial when they are applied to metacomputing and cluster of cluster systems, where the communication costs are an order of magnitude different depending on the relative position of the processor nodes.
Detection of neuropeptide Y and its mRNA in megakaryocytes: enhanced levels in certain autoimmune mice. (1987)

Neuropeptide tyrosine (neuropeptide Y, NPY) is a potent vasoconstrictor with a wide distribution in the central and peripheral nervous systems. Here we show that high levels of rat NPY mRNA are also found in peripheral blood cells, bone marrow, lung, and spleen. Furthermore, radioimmunoassay revealed high levels of NPY-like peptide in these tissues. In mice, the levels of splenic NPY mRNA and immunoreactive peptide differed extensively between strains and were greatly elevated in several strains (NZB, NZBxW, and BXSB) that develop a disease resembling human systemic lupus erythematosus. Like the rat, the NZB mouse showed a high content of NPY mRNA in peripheral blood cells and bone marrow. Immunohistochemical staining revealed NPY-like immunoreactivity in large cells morphologically identifiable as megakaryocytes in rat bone marrow and in the spleen of the NZB mouse strain. Expression of NPY mRNA in megakaryocytes in rat bone marrow and NZB mouse spleen was confirmed by in situ hybridization. These results indicate that NPY is synthesized in megakaryocytes, implying that NPY can be released from platelets and function as a vasoconstrictor during blood-vessel damage. In addition, the increase in splenic NPY in certain autoimmune mouse strains adds to the list of abnormalities associated with these strains.
Recent Great Lakes Ice Trends (1992)

Analysis of ice observations made by cooperative observers from shoreline stations reveals significant changes in the ice season on the North American Great Lakes over the past 35 years. Although the dataset is highly inhomogeneous and year-to-year variability is also quite large, there is a statistically significant indication that the end of the ice season (as defined by the time at which ice departs from the observer stations in spring) has come increasingly early at a number of locations. The earlier ice departure is reflected in a somewhat earlier spring runoff through the St. Lawrence River over the same time period and correlates with increases in springtime temperatures at stations in the region. This example of a trend toward warmer, earlier springs in the upper Midwest is consistent with results from a number of other regional datasets. Because the ice observations began in the mid-1950s, other analyses, including comparisons with modern satellite datasets, could provide a useful tool for monitoring future climate change.
The Role of Autophagy in Cancer: Therapeutic Implications (2011)

Autophagy is a homeostatic, catabolic degradation process whereby cellular proteins and organelles are engulfed by autophagosomes, digested in lysosomes, and recycled to sustain cellular metabolism. Autophagy has dual roles in cancer, acting as both a tumor suppressor by preventing the accumulation of damaged proteins and organelles and as a mechanism of cell survival that can promote the growth of established tumors. Tumor cells activate autophagy in response to cellular stress and/or increased metabolic demands related to rapid cell proliferation. Autophagy-related stress tolerance can enable cell survival by maintaining energy production that can lead to tumor growth and therapeutic resistance. As shown in preclinical models, inhibition of autophagy restored chemosensitivity and enhanced tumor cell death. These results established autophagy as a therapeutic target and led to multiple early phase clinical trials in humans to evaluate autophagy inhibition using hydroxychloroquine in combination with chemotherapy or targeted agents. Targeting autophagy in cancer will provide new opportunities for drug development, because more potent and specific inhibitors of autophagy are needed. The role of autophagy and its regulation in cancer cells continues to emerge, and studies aim to define optimal strategies to modulate autophagy for therapeutic advantage.
