Laser Tandem Mass Spectrometry in a Time of Flight Instrument (1989)

Abstract We present a new laser tandem mass spectrometry technique in a reflectron time of flight (TOF) instrument. A first pulsed laser performs the multiphoton ionization and the primary photodissociation. A newly designed ion source permits a high mass resolution in the space focus of the 12 cm long first linear TOF, where then the secondary excitation can take place. For high resolution applications the pure secondary or pure metastable mass spectrum of a preselected precursor ion can be recorded using a new reflectron scanning technique. It is also possible to obtain the whole secondary mass spectrum with one cycle using a new postacceleration method. Several techniques for ejection of interfering ions are shown. The features of our techniques are demonstrated at various primary fragments of benzene.
Highly Scalable Coding of Depth Maps with Arc Breakpoints (2012)

Recent work highlights the importance of incorporating geometry information into the compression of depth maps. For many applications, features such as resolution scalability and embedded coding are also highly desirable. JPEG 2000 offers these scalability features but suffers from poor compression performance in the vicinity of strong discontinuities. We propose a novel compression strategy for depth maps that incorporates geometry information while retaining the highly scalable coding properties of JPEG 2000. Our scheme involves two separate image pyramid structures, one for arc breakpoints and other for sub-band samples produced by a breakpoint-adaptive transform. Breakpoints capture geometric attributes and are also amenable to scalable coding. We develop an R-D optimization framework for the breakpoint data. We also use a variation of the EBCOT scheme to produce embedded bit-streams for both the breakpoint and sub-band data, allowing them to be independently and incrementally sequenced based on R-D considerations.
Control of tethered airfoils for a new class of wind energy generator (2006)

The paper investigates the control of tethered airfoils in order to devise a new class of wind generators able to overcome the main limitations of the present aeolian technology based on wind mills. A model taken from the literature is used to simulate the dynamic of a kite which can be controlled by suitably pulling two lines. Energy is generated by a cycle composed of two phases, indicated as the traction and the recovery one. The control unit has two electric drives which act as motors in pulling the lines for controlling the flight or for recovering the kite and as generators if the kite pulls the lines. In each phase, control is obtained by "fast" implementations of suitable NMPC designs. In the traction phase the control is designed such that the kite pulls the lines, maximizing the amount of generated energy. When the maximal length of the lines is reached, the control enters the recovery phase and the kite is driven to a region where the lines can be pulled by the motors until the minimal length is reached, spending a small fraction of the energy generated in the traction phase, and a new traction phase is undertaken. Simulation results are presented, related to a recently built small scale prototype
Media Noise Characteristics of CoCrTa/FeSiAl Perpendicular Magnetic Recording Media (1997)

Media noise characteristics of CoCrTa/FeSiAl perpendicular magnetic recording media were investigated to clarify the effects of underlayer characteristics such as crystalline orientation, surface roughness on the medium noise of double-layer media. A strong correlation was found between maintaining a smooth underlayer surface and attaining a low level of medium noise. Insertion of a Cr layer between the glass substrate and the FeSiAl underlayer and sputtering the underlayer at low Ar-gas pressure are effective in maintaining its surface smoothness. These measures reduce medium noise.
Identifying Pathological Findings in German Radiology Reports Using a Syntacto-semantic Parsing Approach (2013)

In order to integrate heterogeneous clinical information sources, semantically correlating information entities have to be linked. Our discussions with radiologists revealed that anatomical entities with pathological findings are of particular interest when linking radiology text and images. Previous research to identify pathological findings focused on simplistic approaches that recognize diseases or negated findings, but failed to establish a holistic approach. In this paper, we introduce our syntacto-semantic parsing approach to classify sentences in radiology reports as either pathological or non-pathological based on the findings they describe. Although we operate with an incomplete, RadLex-based linguistic resource, the obtained results show the effectiveness of our approach by identifying a recall value of 74.3 % for the classification task. 1
Prosthetic sockets stabilized by alternating areas of tissue compression and release (2011)

A prosthetist makes a conventional socket by wrapping plaster bandage around the residual limb and using the resulting shell to create a positive model. After he or she modifies the plaster, it is used to create a laminated socket. Such sockets are almost perfect cylinders that encapsulate the limb. The bone is centered in soft, compressible tissue that must move aside before the bone can push against the socket to transmit force or torque to the prosthesis. In a compression/release stabilized (CRS) socket, three or more longitudinal depressions compress and displace tissue between the socket wall and the bone to reduce lost motion when the bone is moved with respect to the socket. Release areas between depressions are opened to accommodate displaced tissue. Without these openings provided, the CRS socket will not function as intended. Often, the release areas of compression are the struts of a carbon-fiber frame, and the regions between struts are left open. A frame with openings may be modified by the prosthetist adding a thin membrane fully surrounding the limb but allowing the membrane and underlying tissue to enter the release openings. The membrane may contain electrodes, and it may constitute a roll-on liner that helps suspend the prosthesis. We introduce three socket designs: transradial, transfemoral, and transhumeral.
c‐Fos Expression in Ouabain‐Treated Vascular Smooth Muscle Cells from rat Aorta: Evidence for an Intracellular‐Sodium‐Mediated, Calcium‐Independent Mechanism (2002)

In this study, we examined the effect of Na + ‐K + pump inhibition on the expression of early response genes in vascular smooth muscle cells (VSMC) as possible intermediates of the massive RNA synthesis and protection against apoptosis seen in ouabain‐treated VSMC in our previous experiments. Incubation of VSMC with ouabain resulted in rapid induction of c‐Fos protein expression with an approximately sixfold elevation after 2 h of incubation. c‐Jun expression was increased by approximately fourfold after 12 h, whereas expression of activating transcription factor 2, cAMP/Ca 2+ response element binding protein (CREB)‐1 and c‐Myc was not altered. Markedly augmented c‐Fos expression was also observed under Na + ‐K + pump inhibition in potassium‐depleted medium. Na + ‐K + pump inhibition triggered c‐Fos expression via elevation of the [Na + ] i /[K + ] i ratio. This conclusion follows from experiments showing the lack of effect of ouabain on c‐Fos expression in high‐potassium‐low‐sodium medium and from the comparison of dose responses of Na + ‐K + pump activity, [Na + ] i and [K + ] i content and c‐Fos expression to ouabain. A fourfold increment of c‐Fos mRNA was revealed 30 min following addition of ouabain to the incubation medium. At this time point, treatment with ouabain resulted in an approximately fourfold elevation of [Na + ] i but did not affect [K + ] i . Augmented c‐Fos expression was also observed under VSMC depolarization in high‐potassium medium. Increments in both c‐Fos expression and 45 Ca uptake in depolarized VSMC were abolished under inhibition of L‐type Ca 2+ channels with 0.1 μM nicardipine. Ouabain did not affect the free [Ca 2+ ] i or the content of exchangeable [Ca 2+ ] i . Ouabain‐induced c‐Fos expression was also insensitive to the presence of nicardipine and [Ca 2+ ] o , as well as chelators of [Ca 2+ ] o (EGTA) and [Ca 2+ ] i (BAPTA). The effect of ouabain and serum on c‐Fos expression was additive. In contrast to serum, however, ouabain failed to activate the Elk‐1, serum response factor, CREB and activator protein‐1 transcription factors identified within the c‐Fos promoter. These results suggest that Na + ‐K + pump inhibition triggers c‐Fos expression via [Na + ] i ‐sensitive [Ca 2+ ] i ‐independent transcription factor(s) distinct from factors interacting with known response elements of this gene promoter.
High Affinity Hydroxypiperidine Analogues of 4-(2-Benzhydryloxyethyl)-1-(4-fluorobenzyl)piperidine for the Dopamine Transporter:  Stereospecific Interactions in Vitro and in Vivo (2003)

In our effort to develop high-affinity ligands for the dopamine transporter which might find potential use as cocaine medication, a polar hydroxy substituent was introduced into the piperidine ring of one of our disubstituted lead analogues derived from 1-[2-(diphenylmethoxy)-ethyl]-4-(3-phenylpropyl)piperazine (GBR 12935). Both cis- and trans-3-hydroxy derivatives were synthesized and the racemic trans isomer, (+/-)-5, was further resolved into two enantiomers. Newly synthesized compounds were characterized for their binding affinity at the dopamine, serotonin, and norepinephrine transporter systems in rat brain. The two enantiomers (+)-5 and (-)-5 exhibited marked differential affinities at the dopamine transporter with (+)-5 being 122-fold more potent than (-)-5 in inhibiting radiolabeled cocaine analogue binding (IC(50); 0.46 vs 56.7 nM) and 9-fold more active for inhibiting dopamine uptake (IC(50); 4.05 vs 38.0 nM). Furthermore, the most active (+)-5 was 22-fold more potent at the dopamine transporter compared to the standard GBR 12909. Absolute configuration of one of the enantiomers was determined unambiguously by X-ray structural analysis. In in vivo locomotor activity studies, the enantiomer (+)-5 and the racemic (+/-)-5, but not (-)-5, exhibited stimulant activity with a long duration of effect. All three compounds, (+)-5, (-)-5, and (+/-)-5, within the dose range tested, partially (50%) but incompletely (80%) produced cocaine-like responses in mice trained to discriminate 10 mg/kg ip cocaine from vehicle. Compound (-)-5 was distinctive in this regard in that, unlike (+)-5 and (+/-)-5, it did not affect locomotor activity yet, but similar to them, was able to engender (albeit incompletely) cocaine-like responses.
Implementation and Experiments with an Algorithm for Parallel Scheduling of Complex Dags under Uncertainty (2006)

Our earlier paper introduced a parallel scheduling problem where a directed acyclic graph modeling t tasks and their dependencies needs to be executed on n unreliable workers. Worker i executes task j correctly with probability p i,j . The goal is to find a regimen Σ, that dictates how workers get assigned to tasks (possibly in parallel and redundantly) throughout execution, to minimize the expected completion time. The paper provided a polynomial time algorithm for the problem restricted to the case when dag width and the number of workers are at most a constant, and showed necessity of these restrictions, unless P=NP. The current paper describes algorithm engineering approaches used to produce an efficient implementation of the algorithm, and experiments demonstrating how the algorithm scales.
Method for gaseous sand consolidation treatment of weak gas sands. [using silicon halide vapor] (1977)

In a relatively weak water-wet gas-producing reservoir in which a liquid tends to impair the gas production, the rock strength is increased by injecting a silicon polyhalide vapor, such as silicon tetrachloride vapor, mixed with a relatively inert gas, so that the silicon halide converts the rock-wetting water to a rock-strengthening silica gel.
Fluorinated neuroleptics of the 10-piperazino-10,11-dihydrodibenzo[b,f]thiepin series; 6-Fluoro derivatives of perathiepin, octoclothepin, doclothepin and some related compounds (1979)

The synthesis of a series of 6-fluoro-10-piperazino-10,11-dihydrodibenzo[ b,f ]thiepins Ic-IIIc , Vc and VIc is described; these compounds are derivatives of the neuroleptic agents perathiepin ( Ia ), octoclothepin ( IIIa ), doclothepin ( Va ) and their hydroxyethyl analogues IIa and VIa in which the metabolic hydroxylation to position 6 was made impossible by blockade. The synthesis used common procedures via the intermediates VII-XVIII . Fluorination in position 6 does not influence much the pharmacological profile of the compounds indicating that hydroxylation in position 6 is only a minor metabolic pathway. The most interesting substance is the 6-fluoro derivative of octoclothepin ( IIIc ) which is a potent central depressant and neuroleptic agent with some protraction of the sedative effects.
Phosphoric Acid Loaded Azo (−N═N−) Based Covalent Organic Framework for Proton Conduction (2014)

Two new chemically stable functional crystalline covalent organic frameworkds (COFs) (Tp-Azo and Tp-Stb) were synthesized using the Schiff base reaction between triformylphloroglucinol (Tp) and 4,4'-azodianiline (Azo) or 4,4'-diaminostilbene (Stb), respectively. Both COFs show the expected keto-enamine form, and high stability toward boiling water, strong acidic, and basic media. H3PO4 doping in Tp-Azo leads to immobilization of the acid within the porous framework, which facilitates proton conduction in both the hydrous (σ = 9.9 × 10(-4) S cm(-1)) and anhydrous state (σ = 6.7 × 10(-5) S cm(-1)). This report constitutes the first emergence of COFs as proton conducting materials.
Syncopation (2005)

Real-time garbage collection has been shown to be feasible, but for programs with high allocation rates, the utilization achievable is not sufficient for some systems.Since a high allocation rate is often correlated with a more high-level, abstract programming style, the ability to provide good real-time performance for such programs will help continue to raise the level of abstraction at which real-time systems can be programmed.We have developed techniques that allow generational collection to be used despite the problems caused by variance in program behavior over the short time scales in which a nursery can be collected. Syncopation allows such behavior to be detected by the scheduler in time for allocation to by-pass the nursery and allow real-time bounds to be met.We have provided an analysis of the costs of both generational and non-generational techniques, which allow the trade-offs to be evaluated quantitatively. We have also provided measurements of application behavior which show that while syncopation is necessary, the need for it is rare enough that generational collection can provide major improvements in real-time utilization. An additional technique, arraylet pre-tenuring, often significantly improves generational behavior.
Manufacturing large diameter GaAs substrates for epitaxial devices by VB method (2002)

The vertical boat (VB) method has advantages in the growth of substrates for epitaxial devices. Low residual strain and low dislocation four inch GaAs crystals are manufactured with good reproducibility. Low residual strain reduces slip line occurrence and low dislocation density enables growth of low defects in epitaxial layers. FETs fabricated on carbon doped high resistivity VB substrates show high breakdown voltage. Vth was stable at higher drain voltages. Six inch GaAs crystals are also grown by VB and show adequate characteristics.
Improvement of Robustness in Pupil Detection Assuming a Constant Interpupillary Distance in a Video-Based Eye-Gaze Detection System (2012)

In the pupil-corneal reflection detection-based eye-gaze detection method, glasses reflection of near-infrared LED light sources for producing the corneal reflection is misdetected as the pupil when a user wears eyeglasses. To improve the robustness of the pupil detection, we propose novel pupil searching and tracking methods using two stereo-calibrated cameras and light sources. The pupil searching method detects the true pair of the right and left pupils under the constraints of the suitable 3-D interpupillary distance and 3-D position of the pair, which are given in advance. Even if one pupil is not detected in the image of either camera owing to the glasses reflections, the pupil tracking method estimates the 3-D coordinates of the undetected pupil by using the constant interpupillary distance and the temporal continuity of the 3-D coordinates of the moving pupil. The experimental results show that the accuracy of pupil searching and tracking was better than that of the conventional one-camera method.
New antibiotic XK-62-2 (sagamicin). II. Taxonomy of the producing organism, fermentative production and characterization of sagamicin. (1975)

Cultures of Micromonospora species, strains MK 65 and MK 62, were found to produce a new antibiotic XK-62-2 (Sagamicin). Antibacterial and paperchromatographic data on an eluate from IRC50 treatment of fermentation beers indicated that XK62-2 is a new antibiotic with broad spectrum, basic, and water-soluble properties, probably closely related to the gentamicin C group of antibiotics.
Inexpensive method for producing macroporous silicon particulates (MPSPs) with pyrolyzed polyacrylonitrile for lithium ion batteries (2012)

One of the most exciting areas in lithium ion batteries is engineering structured silicon anodes. These new materials promise to lead the next generation of batteries with significantly higher reversible charge capacity than current technologies. One drawback of these materials is that their production involves costly processing steps, limiting their application in commercial lithium ion batteries. In this report we present an inexpensive method for synthesizing macroporous silicon particulates (MPSPs). After being mixed with polyacrylonitrile (PAN) and pyrolyzed, MPSPs can alloy with lithium, resulting in capacities of 1000 mAhg(-1) for over 600+ cycles. These sponge-like MPSPs with pyrolyzed PAN (PPAN) can accommodate the large volume expansion associated with silicon lithiation. This performance combined with low cost processing yields a competitive anode material that will have an immediate and direct application in lithium ion batteries.
Localization of protective epitopes of the amino terminus of type 5 streptococcal M protein. (1986)

We have used a set of overlapping chemically synthesized peptides representing the amino terminus of type 5 streptococcal M protein to localize protective, as opposed to nonprotective and tissue-crossreactive epitopes that might be appropriate for vaccine formulations. Rabbit antisera raised against SM5(1-35) reacted in high titer with pep M5 by ELISA and opsonized type 5 streptococci. None of the antisera crossreacted with human heart tissue or myosin. Antisera against SM5(26-35) reacted with SM5(1-35) and pep M5 but failed to opsonize type 5 streptococci. Particle-phase ELISA indicated that SM5(26-35) antibodies were directed against nonprotective determinants of pep M5 that were not exposed on the surface of viable organisms. Opsonization and ELISA inhibition assays showed that, of the SM5(1-35) antibodies that reacted with M5, all were inhibited by SM5(14-35), whereas none was inhibited by SM5(26-35), suggesting that the protective epitopes of SM5(1-35) resided between residues 14 and 26. This was confirmed by subsequent chemical synthesis of this region; SM5(14-26) totally inhibited SM5(1-35) antibodies that reacted with pep M5 in ELISA, and completely inhibited opsonization of type 5 streptococci by SM5(1-35) antibodies. SM5(14-26) evoked high titers of type-specific, opsonic antibodies against type 5 streptococci, confirming the protective immunogenicity of this 13-residue peptide of type 5 M protein.

Menu-Match: Restaurant-Specific Food Logging from Images (2015)

Logging food and calorie intake has been shown to facilitate weight management. Unfortunately, current food logging methods are time-consuming and cumbersome, which limits their effectiveness. To address this limitation, we present an automated computer vision system for logging food and calorie intake using images. We focus on the "restaurant" scenario, which is often a challenging aspect of diet management. We introduce a key insight that addresses this problem specifically: restaurant plates are often both nutritionally and visually consistent across many servings. This insight provides a path to robust calorie estimation from a single RGB photograph: using a database of known food items together with restaurant-specific classifiers, calorie estimation can be achieved through identification followed by calorie lookup. As demonstrated on a challenging Menu-Match dataset and an existing third party dataset, our approach outperforms previous computer vision methods and a commercial calorie estimation app. Our Menu-Match dataset of realistic restaurant meals is made publicly available.
