D-optimization based mapping calibration of air mass flow in combustion engines (2016)

In this paper, a mapping calibration method based on D-optimization algorithm is proposed and applied to the air mass calibration problem. The first procedure is to carry out a preliminary experiment around the main operating domain, and the polynomial regression model is chosen by minimum corrected Akaike Information Criterion (cAIC) criteria. The second procedure is to calculate D-optimal design of experiment for the given model. The experiment results on a full-scale engine test bench is demonstrated to confirm that the proposed method can provide the precise model.
Reliability Assessment of Fan-Out Packages Using High Resolution Moiré Interferometry and Synchrotron X-Ray Microdiffraction (2016)

Measurement and simulation of the stress state in the silicon die of a wafer-level fan out package can be difficult due to the complexity of high density packaging structures and the uncertainties in material properties at the nanoscale, yet these stresses directly affect the electrical behavior of the embedded active devices due to the piezoresistive effect in silicon. In this study, the residual stresses and thermal stresses in die-on-board, fan-out packages are measured using high resolution moiré interferometry and synchrotron x-ray microdiffraction. The results are then used to verify the materials database used in the finite element analysis (FEA) with the purpose of developing a quantitative method to characterize the stress behavior and its effect on charge carrier mobilities. The underfill effect is investigated by comparing two underfills, one with a moderate glass transition temperature (Tg) and one with a low Tg, to a control with no underfill. High resolution moiré interferometry is used to map the actual deformation of the package cross-section subjected to a negative thermal load, while synchrotron x-ray microdiffraction produces Laue peaks, which are analyzed to extract stress, strain, and lattice deformation data at room temperature. These experiments, in which the separate underfill conditions demonstrated distinct deformation patterns, are used to validate the material and load parameters of the FEA model, which in turn is used to calculate the mobility change.
Differential effects of neurotrophins on ocular dominance plasticity in developing and adult cat visual cortex (2000)

In the present study we examine the influence of neurotrophins on experience-dependent synaptic rearrangement in developing and adult visual cortex. Brain-derived neurotrophic factor (BDNF) or nerve growth factor (NGF) was continuously infused into cortical area 18, and the functional architecture of the cortex was examined by use of optical and electrophysiological recording techniques. In kittens, BDNF infusion during monocular deprivation (MD) reversed the normally occurring ocular dominance (OD) shift towards the non-deprived eye so that the deprived eye dominated the BDNF-treated cortex after MD. Under conditions of equal activation of thalamocortical synapses, i.e. when animals were either subject to binocular deprivation (BD) or reared without deprivation, BDNF infusion did not disrupt binocularity of cortical units, but reversed the natural OD bias towards the contralateral eye in favour of the ipsilateral eye. In addition, BDNF treatment in kittens led to a loss of the orientation selectivity of cortical units irrespective of rearing conditions. In adult animals, BDNF influenced neither OD distributions nor orientation selectivity. The effect of NGF was markedly different. It was ineffective in kittens but in adult animals it caused a shift of OD towards the deprived eye when MD was combined with NGF infusion. However, in this case orientation selectivity was preserved. Thus, both neurotrophins have profound activity- and age-dependent effects on the functional architecture of the visual cortex. Moreover, our results indicate that simple substitution of neurotrophins in excess is unlikely to compensate for deprivation effects by preserving or restoring the normal functional architecture of the cortex.
An Efficient Piecewise Hashing Method for Computer Forensics (2008)

Hashing, a basic tool in computer forensics, is used to ensure data integrity and to identify known data objects efficiently. Unfortunately, intentional tiny modified file can not be identified using this traditional technique. Context triggered piecewise hashing separates a file into pieces using local context characteristic, and produces a hash sequence as a hash signature. The hash signature can be used to identify similar files with tiny modifications such as insertion, replacement and deletion. The algorithm of currently available scheme is designed for junk mail detection, which is low efficient and not suitable for file system investigation. In this paper, an improved algorithm based on the Store-Hash and Rehash idea is developed for context triggered piecewise hashing technique. Experiment results show that the performance of speed and the ability of similarity detection of the new scheme are better than that of spamsum. It is valuable for forensics practice.
Non-linear surface impedance taking account of thermal effect [induction heating] (2001)

A surface impedance depending on magnetic field and temperature Z/sub s/(H, T) is defined. The proposed definition is carried out from 1-D nonlinear step by step solution of magnetodynamic equation for a range of temperatures. The goal of the Z/sub s/(H, T) determination is an accurate and rapid modeling for induction heating applications.
Mycobiota Associated with the Coffee Berry Borer (Coleoptera: Scolytidae) and Its Galleries in Fruit (2004)

Fungi associated with the coffee berry borer, Hypothenemus hampei (Ferrari), are determined and galleries in coffee fruit, Coffea arabica L., are described. In total, 13 fungus species were found to be associated with the coffee berry borer and its galleries. These fungi were divided into four functional groups: 1) saprobic fungi that the borer uses as food: Fusarium heterosporum Nees ex Fries, Cladosporium sp., Cladosporium oxysporum Berkeley & Curtis, and Penicillium echinulatum Fassatiová; 2) saprobic fungi that degrade borer feces: Aspergillus flavus Link, Aspergillus niger Tieghem, Mucor luteus Linnemann, Penicillium sp. 1, Humicola grisea Traaen, and Gliocladium penicilloides Corda; 3) fungi that are coffee parasites: Fusarium oxysporum Schlechetend and Fusarium solani (Martius) Saccardo; and 4) the entomopathogenic fungus Beauveria bassiana (Balsamo-Crivelli) Vuillemin. The same fungi were found on and inside the insect as well as in galleries and were components of the insect’s diet. Apparent interference of B. bassiana by F. solani was observed.

A Near-Infrared Ratiometric Fluorescent Probe for Highly Selective Recognition and Bioimaging of Cysteine (2019)

A benzothiazole-based near-infrared (NIR) ratiometric fluorescent probe (<b>HBT-Cys</b>) was developed for discriminating cysteine (Cys) from homocysteine (Hcy) and glutathione (GSH). The probe was designed by masking phenol group in the conjugated benzothiazole derivative with methacrylate group that could be selectively removed by Cys, and therefore an intramolecular charge transfer (ICT) fluorescence was switched on in the NIR region. In the absence of Cys, the probe exhibited a strong blue fluorescence emission at 431 nm, whereas a NIR fluorescence emission at 710 nm was significantly enhanced accompanied by a decrease of emission at 431 nm in the presence of Cys, allowing a ratiometric fluorescence detection of Cys. The fluorescence intensity ratio (I<sub>710nm</sub>/I<sub>431nm</sub>) showed a good linear relationship with Cys concentration of 1-40 μM with the detection limit of 0.5 μM. The sensing mechanism was explored based on MS experimental analysis and DFT theoretical calculation. Moreover, the fluorescent probe was successfully used for fluorescence bioimaging of Cys in living cells.
Building Together (2019)

In late 2017, Uber was nearly a year into a complete redesign of its driver-facing mobile app. This case study describes the research program we executed to support the app's global beta launch, which aimed to "Build Together" with drivers across different geographies. With the goal of minimizing the time-space-cognitive distance between beta drivers and the product team, we deployed researchers in 7 cities for a 3-week research sprint, combining four high-touch ethnographic methods to understand drivers' reaction to the product. Unusually, we used an internal Google+ social media site to post a continual stream of raw, unsynthesized "atomic evidence" from research activities. The G+ unexpectedly went viral, creating extremely high engagement, impact, and stakeholder sentiment. Here we discuss the pros, cons, and impact of our approach, and also how success came from creating space for others to create, engage with, and act on raw evidence from the field.
L1pred: A Sequence-Based Prediction Tool for Catalytic Residues in Enzymes with the L1-logreg Classifier (2012)

To understand enzyme functions, identifying the catalytic residues is a usual first step. Moreover, knowledge about catalytic residues is also useful for protein engineering and drug-design. However, to experimentally identify catalytic residues remains challenging for reasons of time and cost. Therefore, computational methods have been explored to predict catalytic residues. Here, we developed a new algorithm, L1pred, for catalytic residue prediction, by using the L1-logreg classifier to integrate eight sequence-based scoring functions. We tested L1pred and compared it against several existing sequence-based methods on carefully designed datasets Data604 and Data63. With ten-fold cross-validation, L1pred showed the area under precision-recall curve (AUPR) and the area under ROC curve (AUC) of 0.2198 and 0.9494 on the training dataset, Data604, respectively. In addition, on the independent test dataset, Data63, it showed the AUPR and AUC values of 0.2636 and 0.9375, respectively. Compared with other sequence-based methods, L1pred showed the best performance on both datasets. We also analyzed the importance of each attribute in the algorithm, and found that all the scores contributed more or less equally to the L1pred performance.
Reaction of three cool-season annual legume species to Meloidogyne arenaria and Heterodera glycines (1993)

Breeding lines and accessions of Vicia villosa Roth, V. sativa L., and Lathyrus hirsutus L. were evaluated for resistance to Meloidogyne arenaria race 2 and Heterodera glycines race 4 in the greenhouse. Vicia villosa accessions were susceptible to M. arenaria whereas some V. sativa accessions were completely resistant. All L. hirsutus accessions were sensitive to M. arenaria; however, nematode reproduction and damage symptoms were significantly less than on the hairy vetch control. None of three cool-season legumes was susceptible to H. glycines.
Electrical modulation schemes for imaging by self-mixing in terahertz quantum cascade lasers (2014)

The use of a single terahertz (THz) quantum cascade laser (QCL) device as both emitter and detector in a self-mixing (SM) scheme allows for the development of fast, sensitive and compact coherent systems for imaging and interferometry. Due to the continuous wave nature of SM experiments, a mechanical chopper is commonly used to enable lock-in detection. However, this imposes an upper limit (~200Hz) on the modulation frequency, which is far below the ~10–100 GHz optical feedback response bandwidth of the QCL. We overcome this bottleneck using electrical modulation schemes for two- (2D) and three-dimensional (3D) imaging. Furthermore, by applying a saw-tooth modulation we demonstrate a swept-frequency self-delayed homodyne scheme for coherent 3D imaging without the need for longitudinal displacement of the sample. Using this same scheme we also demonstrate measurement of the current tuning coefficient of the QCL.
Syntharch: Interactive Image Search with Attribute-Conditioned Synthesis (2020)

The use of interactive systems has been found to be a promising approach for content-based image retrieval, the task of retrieving a specific image from a database based on its content. These systems allow the user to refine the set of results iteratively until the target is reached. In order to proceed with the search efficiently, conventional methods rely on some shared knowledge between the user and the system, such as semantic visual attributes of the images. Those approaches demand the images to be semantically labeled and introduce a semantic gap between the two parties' understanding. In this paper, we explore an alternative approach to interactive image search where feedback is elicited exclusively in visual forms, therefore eliminating the semantic gap and allowing for a generalized version of the method to operate on unlabeled databases. We present Syntharch, a novel interactive image search approach which uses synthesized images as options for feedback, instead of asking textual questions to gain information on the relative attribute values of the target image. We further demonstrate that by using synthesized images rather than real images retrieved from the database as feedback options, Syntharch causes less confusion to the user. Finally, we establish that our proposed search method performs similarly or better in comparison to the conventional approach.
Multi-target Tracking with Motion Context in Tensor Power Iteration (2014)

Interactions between moving targets often provide discriminative clues for multiple target tracking (MTT), though many existing approaches ignore such interactions due to difficulty in effectively handling them. In this paper, we model interactions between neighbor targets by pair-wise motion context, and further encode such context into the global association optimization. To solve the resulting global non-convex maximization, we propose an effective and efficient power iteration framework. This solution enjoys two advantages for MTT: First, it allows us to combine the global energy accumulated from individual trajectories and the between-trajectory interaction energy into a united optimization, which can be solved by the proposed power iteration algorithm. Second, the framework is flexible to accommodate various types of pairwise context models and we in fact studied two different context models in this paper. For evaluation, we apply the proposed methods to four public datasets involving different challenging scenarios such as dense aerial borne traffic tracking, dense point set tracking, and semi-crowded pedestrian tracking. In all the experiments, our approaches demonstrate very promising results in comparison with state-of-the-art trackers.
Pituitary Adenomas in Children and Adolescents (2010)

Clinical manifestations and outcomes of pituitary adenomas in children are not clearly defined. We retrospectively reviewed cases of pituitary adenomas in children 0-18 years treated at MassGeneral Hospital for Children over 15 years. Thirty-five patients were identified. Age at presentation was 7-18 years. Seventeen had prolactinomas, 3 had somatotropinomas, and 15 had Cushing disease. Thirteen prolactinoma patients were female and most commonly presented with oligomenorrhea (10/13) and galactorrhea (7/13). Nine were successfully treated medically. Two somatotropinoma patients presented with visual disturbances; the third was an incidental finding. Two were cured by trans-sphenoidal surgery (TSS). Thirteen Cushing disease patients were initially cured by TSS; six recurred after 3-6 years. Patients with or without recurrence did not differ for age, tumor-size and hormone levels. The high recurrence rate of Cushing disease in our series (46%) compared with adults treated surgically at this institution (7%) emphasizes the need for long-term follow-up.
Elektrochemische und pulsradiolytische Reduktion von (Pentamethylcyclopentadienyl)(polypyridyl)rhodium‐Komplexen (1989)

Für 11 wurde die Bildung von Addukten mit Lewis‐Säuren sowie die leicht erfolgende oxidierende Addition, wobei selbst CH 2 Cl 2 reagiert, untersucht. – Die elektrochemische Reduktion R III /Rh I läuft als irreversibler Zweielektronenprozeß unter Verlust des Liganden L ab. Die Peakpotentiale für die Reduktion liegen bei –0.75 bis –0.95 V (gegen GKE) in Acetonitril, Dichlormethan oder Wasser, und der Abstand des kathodischen vom anodischen Peak [Rückoxidation von Cp * Rh(ppy)] beträgt 150–300 mV. Die Werte werden mit den für entsprechende Phosphankomplexe oder das 2,2′‐Bipyrazinderivat 7 ermittelten verglichen. Die pulsradiolytische Reduktion Rh III /Rh II ermöglicht die Bestimmung der Geschwindigkeitskonstanten 2. Ordnung für dessen Disproportionierung zu etwa 10 9 s −1 ·mol −1 ·l. – In protischer Lösung schließt sich an die Reduktion eine Protonierung an, die im elektrochemischen Experiment demonstriert werden kann. Pulsradiolytisch wurden Geschwindigkeitskonstanten k 2 von etwa 10 8 s −1 ·mol −1 ·l. in neutraler bis alkalischer Lösung gemessen. Die protonierten Komplexe [Cp * Rh(ppy)H] + reagieren langsamer mit Protonen zu H 2 unter Rückbildung des Ausgangskomplexes [Cp * Rh(ppy)H 2 O] 2+ weiter ( k 2 = 50–250 s −1 ·mol −1 .l). Die Bedeutung der Ergebnisse für die katalytische und die lichtgetriebene Protonenreduktion wird diskutiert.
Hybrid wheat : results and problems (1993)

Diese Arbeit gibt einen zusammenfassenden Ueberblick ueber die Erforschung und Entwicklung von Hybridweizen. Sie ist in drei Hauptabschnitte gegliedert: Die Heterosis beim Kornertrag und andere wichtige Eigenschaften, die Systeme der maennlichen Sterilitaet und die Hybrid-Saatguterzeugung. Beschrieben werden mehr als 40 Jahre Arbeit mit dieser Zuechtungsstrategie, an der auch die meisten der wichtigen Weizenanbaulaender beteiligt waren. Es wird dargelegt, dass viele Aspekte der Grundlagenforschung zusaetzlich zur umfangreichen Zuechtungspraxis bei der Suche nach Hybridsorten einbezogen wurden: Auf beiden Wegen haben die Zuechter im Interesse einer hoeheren oder effizienteren Produktivitaet moeglichst viele Systemkomponenten der Pflanze zu nutzen versucht. Auch wenn Vorteile fuer die private Wirtschaft oft als Hauptmotiv einer Hybridzuechtung angesehen wurden, laesst sich doch aus der Literatur auch eindeutig ersehen, dass ein grosser Teil der Arbeiten ueber Hybridweizen oeffentlich gefoerdert wurde. Auch wird nach Gruenden gefragt, nach denen wirtschaftlich erfolgreiche F1-Hybridsorten beim Weizen trotz vielversprechender Anfaenge und im Gegensatz zu anderen Kulturpflanzenarten schwer zu definieren sind. Schliesslich haben Biologie und Umwelt das Ergebnis beim Weizen beeinflusst, fuer das gleichermassen auch die deutlichen Erfolge der Zuechtung von Liniensorten bestimmend waren, deren Potential noch keineswegs ausgeschoepft ist. Abschliessend untersucht die Arbeit die kuenftigen Perspektiven fuer Hybridweizen im Lichte moeglicher Herausforderungen an die Menschheit.
Efficacy of a Latex Agglutination Test for Rapid Identification of Staphylococcus aureus: Collaborative Study (1996)

Fifteen laboratories completed a collaborative study comparing the efficacy of a latex agglutination kit (Aureus Test) with that of AOAC Official Method 987.09 (coagulase test for identification of Staphylococcus aureus). Each laboratory analyzed 240 strains of bacteria, including 160 isolates of S. aureus and 80 isolates of other bacteria. Upon receipt of cultures, collaborators subcultured each isolate on both tryptic soy agar (TSA) and Baird-Parker agar medium (BPA) to determine whether the growth medium has any effect on either method. For cultures grown on TSA, the latex test had sensitivity and specificity rates of 99.2 and 97.1%, respectively, whereas the coagulase test had respective rates of 98.4 and 92.5%. For cultures able to grow on BPA, the latex test had sensitivity and specificity rates of 99.2 and 96.6%, respectively, while the coagulase test had respective rates of 98.3 and 91.3%. By using the McNemar pairwise comparison test of the 2 methods, the false-positive and false-negative rates of the latex test were significantly lower (p < 0.01) than those of the coagulase test for strains grown either on TSA or BPA. The latex agglutination test for identification of S. aureus isolated from foods has been adopted by AOAC INTERNATIONAL.

Optimization of Fe2 + /solids content ratio for a novel sludge heavy metal bioleaching process (2008)

A novel bioleaching process, preincubation bioleaching (PB) has been recently developed in our laboratory for decontamination of heavy-metal-laden sewage sludge by removing the toxic low molecular weight organic acids using an isolated degradative yeast species. The objective of the present study was to optimize Fe2+ /solids content ratio required for removing heavy metals from sewage sludge by using this novel process at high solids content. Results from the present study showed that regardless of the Fe2+ /solids content ratio iron oxidation and sludge acidification could be achieved within 2 days confirming the effectiveness of PB in reducing the inhibitory organic acids. When PB was conducted at an elevated solids content of 3%, Fe2 +/solids content ratio could be reduced to 0.75:1, 1:1 and 1.25:1 for solubilization of Zn, Cu and Cr respectively. Under this optimized bioleaching conditions, the following solubilization efficiencies were obtained after 8 days of bioleaching: 100% Zn, 96% Cu, 60% Cr with no reduction in nutrient contents. Hence, bioleaching at elevated solids contents represents a more economical way for decontamination of heavy-metal-laden sewage sludge while preserving its fertility values.
