Multimodal Food Journaling (2018)

A food journal is essential for improving health and well-being. However, journaling every meal is extremely difficult because it depends on user initiative and intervention. Current approaches to food journaling are both potentially inaccurate and tedious, causing people to abandon their journals very soon after they start. In this paper, we propose a proactive and reactive mechanism that can significantly reduce user initiative while still remaining highly accurate. We first suggest a novel eating moment recognition technique using heart rate and activity patterns to trigger a food journaling process in a proactive manner. We then begin the food journaling process via voice command which utilized natural language processing when logging meals, which increases the ease of reactive self-reporting. Lastly, we enhance the food journal by automatically assessing ecological moments of eating activity through our personal chronicle system. We verified the method from a feasibility study conducted with three people for three months in their day-to-day lives. Our approach is designed to be unobtrusive and practical by leveraging multi-modal sensor data through the most common device combination of a smartphone and wearable device.
High-power, wide-temperature range operation of 1.3-μm gain-coupled DFB lasers with automatically buried InAsP absorptive grating (1996)

DFB lasers operating at 1.3 μm with gain-coupling structure show single-mode operation over a wide temperature range of -20/spl sim/85/spl deg/C and up to a high power of 130 mW. These lasers have InAsP absorptive grating, which can be formed by a substantially simplified fabrication process, involving annealing a corrugated InP substrate in an atmosphere of mixed arsine and phosphine.

[Study on interaction of acetaldehyde with thioalcohols by infrared spectroscopy]. (2008)

The reaction of acetaldehyde with thioalcohols, Mesna (monothiol) and Unithiol (vicinal dithiol) was investigated by infrared spectroscopy. Unithiol was more active in the reaction of acetaldehyde fixation than Mesna. This property may explain high efficiency of peroral administration of Unithiol for treatment of postalcoholic intoxication (hangover).

Millimicrosecond Magnetic Switching and Storage Element (1959)

A magnetic rod suitable for performing the logical switching and storage functions required in a digital computer has been developed. The magnetic element consists of a silver-coated glass rod upon which is electroplated a Fe-Ni alloy several thousand angstroms thick. A single element for a coincident-current memory requiring two inputs, an inhibit winding, and a sense winding would consist of four separate single layer concentric solenoids wound over the magnetic rod. Memory matrices, each consisting of many solenoids, can be stacked and simultaneously threaded with the rod. The switching speed of the element operating in a coincident-current mode is approximately 70 mμsec. The output voltage generated across a ten-turn sense winding is 200 to 500 mv depending upon the alloy thickness. The rod is also suitable as a multi-input logical switch. Separate inhibiting windings wound over the rod perform the NOR function of its input literals. A total of thirty separate inhibiting windings have been demonstrated in the laboratory. Satisfactory operation in the 2- to 5-Mc range using transistors in conjunction with the rod has been shown to be practical. Continuous plating and testing in conjunction with automatic machine winding techniques make the rod appear economically attractive in digital computer applications.
A rapid, automated surface protein profiling of single circulating exosomes in human blood (2016)

Circulating exosomes provide a promising approach to assess novel and dynamic biomarkers in human disease, due to their stability, accessibility and representation of molecules from source cells. However, this potential has been stymied by lack of approaches for molecular profiling of individual exosomes, which have a diameter of 30-150 nm. Here we report a rapid analysis approach to evaluate heterogeneous surface protein expression in single circulating exosomes from human blood. Our studies show a differential CD47 expression in blood-derived individual circulating exosomes that is correlated with breast cancer status, demonstrating a great potential of individual exosome profiles in biomarker discovery. The sensitive and high throughput platform of single exosome analysis can also be applied to characterizing exosomes derived from other patient fluids.
Packet Sniffer Detection with AntiSniff (2003)

Packet sniffing is a technique of monitoring every packet that crosses the network. A packet sniffer is a piece of software or hardware that monitors all network traffic. The security threat presented by sniffers is their ability to capture all incoming and outgoing traffic, including clear-text passwords and usernames or other sensitive material. While packet sniffers can be fully passive, some aren’t, therefore they can be detected. This paper discusses the different methods that AntiSniff uses to detect these sniffing programs.
Escherichia coli cell division protein FtsZ is a guanine nucleotide binding protein. (1993)

FtsZ is an essential cell division protein in Escherichia coli that forms a ring structure at the division site under cell cycle control. The dynamic nature of the FtsZ ring suggests possible similarities to eukaryotic filament forming proteins such as tubulin. In this study we have determined that FtsZ is a GTP/GDP binding protein with GTPase activity. A short segment of FtsZ is homologous to a segment in tubulin believed to be involved in the interaction between tubulin and guanine nucleotides. A lethal ftsZ mutation, ftsZ3 (Rsa), that leads to an amino acid alteration in this homologous segment decreased GTP binding and hydrolysis, suggesting that interaction with GTP is essential for ftsZ function.

Guard Trace Design for Improvement on Transient Waveforms and Eye Diagrams of Serpentine Delay Lines (2010)

This paper investigates the utilization of the guard traces to improve the eye opening and jitter for serpentine delay lines. It is found that the guard trace can reduce the original time-domain transmission (TDT) and time-domain reflection (TDR) crosstalk noises by more than 50%, if shorted by only two grounded vias at both ends of the trace. The time domain analysis as well as the associated simple circuit modeling is presented to explain the occurrence of noise cancellation mechanism on the guard trace. In addition, narrow signal trace is proposed to improve the TDR waveform by compensating the impedance mismatch due to the inserted guard traces. Finally, the HSPICE simulation and time-domain measurements of crosstalk noises, TDR/TDT waveforms, and eye diagrams are performed to validate the proposed analysis and design.

Syntactic parsing of chat language in contact center conversation corpus (2016)

Chat language is often referred to as Computer-mediated communication (CMC). Most of the previous studies on chat language has been dedicated to collecting "chat room" data as it is the kind of data which is the most accessible on the WEB. This kind of data falls under the informal register whereas we are interested in this paper in understanding the mechanisms of a more formal kind of CMC: dialog chat in contact centers. The particularities of this type of dialogs and the type of language used by customers and agents is the focus of this paper towards understanding this new kind of CMC data. The challenges for processing chat data comes from the fact that Natural Language Processing tools such as syntactic parsers and part of speech taggers are typically trained on mismatched conditions, we describe in this study the impact of such a mismatch for a syntactic parsing task.
Development of High Boron Content Liposomes and Their Promising Antitumor Effect for Neutron Capture Therapy (2013)

High accumulation and selective delivery of boron into tumor tissue are the most important requirements to achieve the efficient cell-killing effect of boron neutron capture therapy (BNCT) that relies on the nuclear reaction of two essentially nontoxic species, boron-10 ((10)B) and thermal neutrons in boron-loaded tissues. Recent development of boron cluster lipids and their liposomal boron delivery system (BDS) are summarized in this article. Boron compounds that have no affinity to tumor can potentially be delivered to tumor tissues by liposomes, therefore, liposomal BDS would be one of the most attractive approaches for efficient BNCT of various cancers. There are two approaches for BDS: encapsulation of boron compounds into liposomes and incorporation of boron-conjugated lipids into the liposomal bilayer. The combination of both approaches has a potential for reduction of the total dose of liposomes without reducing the efficacy of BNCT.
Sensitive and Structure-Informative <i>N</i>-Glycosylation Analysis by MALDI-MS; Ionization, Fragmentation, and Derivatization (2017)

Mass spectrometry (MS) has become an indispensable tool for analyzing post translational modifications of proteins, including <i>N</i>-glycosylated molecules. Because most glycosylation sites carry a multitude of glycans, referred to as "glycoforms," the purpose of an <i>N</i>-glycosylation analysis is glycoform profiling and glycosylation site mapping. Matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) has unique characteristics that are suited for the sensitive analysis of <i>N</i>-glycosylated products. However, the analysis is often hampered by the inherent physico-chemical properties of <i>N</i>-glycans. Glycans are highly hydrophilic in nature, and therefore tend to show low ion yields in both positive- and negative-ion modes. The labile nature and complicated branched structures involving various linkage isomers make structural characterization difficult. This review focuses on MALDI-MS-based approaches for enhancing analytical performance in <i>N</i>-glycosylation research. In particular, the following three topics are emphasized: (1) Labeling for enhancing the ion yields of glycans and glycopeptides, (2) Negative-ion fragmentation for less ambiguous elucidation of the branched structure of <i>N</i>-glycans, (3) Derivatization for the stabilization and linkage isomer discrimination of sialic acid residues.
Enzymatic dehydrogenation of tryptophan residues of human globins by tryptophan side chain oxidase II. (1984)

Enzymatic dehydrogenation of tryptophan residues in human alpha- and beta-globins has been demonstrated with tryptophan side chain oxidase II, a hemoprotein from Pseudomonas. In 1 M ammonium acetate, pH 4, the enzyme catalyzed the conversion of Trp-14 of alpha-globin to alpha, beta-dehydro-Trp. Under identical conditions, Trp-15 of beta-globin was converted to alpha, beta-dehydro-Trp, whereas Trp-37 was unmodified. No modification was obtained in 0.4% sodium dodecyl sulfate or 8 M urea. The dehydrogenase component of tryptophan side chain oxidase II was also active toward globins in the presence of ferricyanide, whereas tryptophan side chain oxidase I was inert. Upon analyses of the tryptic fragments of the modified beta-globin, two forms of alpha, beta-dehydro-Trp-15 distinguishable by ultraviolet absorption and fluorescence were identified. Each of them rapidly equilibrated with another form on irradiation at 300-380 nm. We tentatively assigned them to two isomers of alpha, beta-dehydro-Trp distinguishable by the configuration around its beta-carbon atom. alpha, beta-Dehydro-Trp in globins and certain polypeptides used herein showed a blue fluorescence at 420 nm. In [alpha, beta-dehydro-Trp 15]beta-globin, the fluorescence was exceptionally intense, the fluorescence yield being comparable to that of NADH. From several lines of evidence, the result was ascribed to the excitation energy transfer from Trp-37 to alpha, beta-dehydro-Trp-15 in the modified beta-globin.
Preparation and Characterization of Poly(Lactic Acid)‐g‐Maleic Anhydride + Starch Blends (2009)

Abstract Poly(lactic acid) (PLA) and starch copolymers are obtained by reactive blending ‐ varying the starch compositions from 0 to 60%. PLA is functionalized with maleic anhydride (MA), obtaining PLA‐g‐MA copolymers using dicumyl peroxide as an initiator of grafting in order to improve the compatibility and interfacial adhesion between the constituents. PLA + starch blends without a compatibilizer do not have sufficient interfacial adhesion. Decomposition temperature of PLA is not affected by grafting. Glass transition temperatures and dynamic mechanical properties are affected since MA has a plasticizing effect. Along with an increasing starch content friction decreases while wear loss volume in pin‐on‐disk tribometry has a minimum at nominal 15% wt. starch but increases at higher starch concentrations. The residual depth in scratching and sliding wear testing has a maximum at 15% starch; there is a minimum of storage modulus E′ determined in dynamic mechanical testing at the same concentration. Microhardness results also reflect the plasticization by MA.
A Statistical Approach to Anomaly Detection in Interdomain Routing (2006)

A number of events such as hurricanes, earthquakes, power outages can cause large-scale failures in the Internet. These in turn cause anomalies in the interdomain routing process. The policy-based nature of border gateway protocol (BGP) further aggravates the effect of these anomalies causing severe, long lasting route fluctuations. In this work we propose an architecture for anomaly detection that can be implemented on individual routers. We use statistical pattern recognition techniques for extracting meaningful features from the BGP update message data. A time-series segmentation algorithm is then carried out on the feature traces to detect the onset of an instability event The performance of the proposed algorithm is evaluated using real Internet trace data. We show that instabilities triggered by events like router mis-configurations, infrastructure failures and worm attacks can be detected with a false alarm rate as low as 0.0083 alarms per hour. We also show that our learning based mechanism is highly robust as compared to methods like exponentially weighted moving average (EWMA) based detection.
A Sustained Release Drug Delivery System Using Calcium Alginate Beads (1985)

Calcium alginate beads impregnated with sulphamethoxazole as model drug were prepared and characterized. Scanning electron microscope was used to examine their surface with and without the drug. The bead average diameter was 1.25mm and the sulphamethoxazole uptake by the beads was about half of the incorporated quantity. The release behaviour was followed using USP dissolution method. The effect on release of factors such as sodium alginate, calcium chloride concentration, pH, hydration and compression were studied. Sodium alginate concentrations had no pronounced effect on the release. The release was found to be a function of calcium chloride concentration. The higher the concentration the lower the release. The smaller the water content the lower the release from the beads. Compression of the beads yields a deformed beads with an increase in their release. Plain calcium alginate beads were not suitable for sulphamethoxazole loading. Sulphamethoxazole diffusion through calcium alginate film was determined. The dissolution patterns were discussed. The system may offer a simple and efficient sustain release preparation.

Making Bertha (2014)

It is August 2013, and we are sitting in what looks like a standard S-Class Mercedes, nosing through traffic in a small town in southern Germany. The streets are narrow and jam-packed with cars, and pedestrians are everywhere. Yet nobody has a hand on the wheel, and nobody has a foot anywhere near the pedals. Still, you can't fault the driving: This car is in charge of itself.
Efficient algorithms for dynamic allocation of distributed memory (2002)

The problem of dynamically allocating and deallocating local memory resources among multiple users in a parallel or distributed system is considered. The goal is to devise an online allocation algorithm that minimizes both the fraction of unused space due to fragmentation of the memory and the slowdown needed by the system to service user requests. The problem is solved in near-optimal fashion by devising an algorithm that allows the memory to be used to 100% of capacity despite the fragmentation and guarantees that service delays will always be within a constant factor of optimal. The algorithm is completely online (no foreknowledge of user activity is assumed) and can accommodate any sequence of insertions and deletions by the users which does not violate global memory bounds. The results have applications in the domain of parallel disk allocation.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Epidermal Growth Factor Stimulation of the Human Gastrin Promoter Requires Sp1 (1995)

Growth factors coordinately regulate a variety of different genes to stimulate cellular proliferation. In the stomach, gastrin, epidermal growth factor (EGF), and transforming growth factor-alpha all mediate gastric mucosal homeostasis by promoting cell renewal. We have previously shown that EGF and phorbol esters stimulate the human gastrin promoter through a novel GC-rich DNA element 5'-(68)GGGGCGGGGTGGGGGG-53 called gERE (gastrin EGF response element). In this report, we show that three factors bind to this element, the transcription factor Sp1 and two fast migrating complexes designated gastrin EGF response proteins (gERP 1 and 2). To understand how these factors bind and confer EGF responsiveness, mutations of gERE were tested in vitro for protein binding and in vivo for promoter activation. Both gel shift assays and UV cross-linking studies revealed that the factors bind to overlapping domains, Sp1 to the 5' half-site and gERP 1 and 2 to the 3' half-site. Placing either the 5' or 3' mutations upstream of a minimal gastrin promoter abolished EGF induction. Therefore both the 5' and 3' domains were required to confer EGF induction. Collectively, these results demonstrate that complex interactions between Sp1 and other factors binding to overlapping gERE half-sites confer EGF responsiveness to the gastrin promoter.
