Thermal forming process design (2005)

Thermal forming metallic components with laser energy is evolving into a viable manufacturing technology with commercial applications spanning diverse domains such as high-volume automotive part production, microelectronic device fabrication and shape tuning turbomachinery airfoils. Research activities are concentrated on quantifying the underlying mechanisms and resulting strain fields and in devising thermal forming strategies and schedules to yield a desired part shape. In this paper we outline a generalized empiric-numeric approach to determine thermal forming induced strain fields and demonstrate results with the nickel-based alloy 718, widely used in aerospace applications. The resulting strain field transfer functional is central to devising thermal forming treatments. Path planning strategies and results of thermal forming a turbomachinery compressor airfoil—a thin freeform 3D shape—are also demonstrated.
Experiences with the Design of B-ISDN Integrated Test System(BITS) (1996)

To ensure interoperability between network components, a test system is understood as a useful facility to test and validate the developed system. In this paper, we deal with design and implementation of the B-ISDN Integrated Test System(BITS). The BITS is composed of functions for conformance and interoperability testing, call simulation and protocol monitoring. The BITS is a flexible test platform for B-ISDN protocol testing. The test configuration of the BITS can be easily and efficiently prepared for testing B-ISDN protocol implementations in a real networking world. This paper presents experiences with the design of BITS, especially the tester architecture, the development of test suites for the B-ISDN signalling protocol, and its application to B-NT system developed by ETRI.
Metallic surfaces as alignment layers for nondisplay applications of liquid crystals (2011)

Nearly all liquid crystal devices use a rubbed organic layer as a method of orienting the liquid crystals. This letter studies the alignment of nematic liquid crystals by rubbed and nonrubbed metallic surfaces. For rubbed metallic films, a homogeneous planar alignment of liquid crystals is found. Nonrubbed metallic surfaces align liquid crystals nonuniformly and randomly. The alignment produced by a single rubbed metallic surface extends from 10 to 50 μm and is stable in time. These results are important because they show that the organic layer may be eliminated for some applications, including tunable microwave and infrared signal processing elements.

Machine perfusion systems for continuous hypothermic perfusion preservation are computer controlled and re-usable. The system of perfusion preservation proved beneficial for for storage of kidneys, particularly those harvested from NHBD donors. The first disposable continuous hypothermic perfusion system which can be used for storage of livers is presented.
HV Fuses with Improved Cyclic Stability ICS <sup>®</sup> (2021)

For decades, high-voltage (HV) fuses have provided economical and most reliable protection of electrical applications standardized by IEC60282-1[1]. They fulfil both either the protection of the circuit components or the energy limitation, fast disconnection to limit negative effects to the corresponding network. They are often used in combination with a second switching-device of limited switching capacity. Typically, such kind of medium-voltage switching - or control-gears handle the switching tasks of the pure operating current of the application up to a certain, but limited level of short-circuit current. In the event of a high-current fault, occurring either on the grid or in one of the components, failure currents may arise which exceed the breaking capacity of this switching device. This is where the “high-voltage high-breaking- capacity fuses” – or HV fuses for short – step in. The development of more compact and economical switchgear solutions requires HV fuses with a reduced power dissipation are still able to handle higher transformer capacities. These now available so-called “Low Loss” fuses [2] provide the well-known protection of transformer circuits even in case of higher transformer capacities up to 3.000 kVA in combination with encapsulated switchgears subjected to IEC 62271–105 [3] as applied in actual renewable applications like wind or solar farms of a higher power level. However, before the “Low-loss” fuses were available HV fuses were also used inside renewable energy systems of a reduced power level. After some years of operational experiences, it became obvious that special attention has to be paid to the additional issue of cyclic stability due to current fluctuations given by nature in case of such renewable energy systems. SIBA decided to take care of this matter by developing a corresponding melting-element system and fuse series with an enhanced cyclic stability called ICS. This new fuse series can be seen as a second step and further development of the known “Low-loss” type. In addition to the improved power loss and thermal situation, this new type is providing an enhanced mechanical cyclic stability in case of current fluctuations inside renewable energy systems.
High-efficiency turquoise-blue electrophosphorescence from a Pt(II)-pyridyltriazolate complex in a phosphine oxide host (2009)

We demonstrate high-efficiency turquoise-blue electrophosphorescence from bis[3,5-bis(2-pyridyl)-1,2,4-triazolato]platinum(II) [Pt(ptp)2] doped in 4-(diphenylphosphoryl)-N,N-diphenylaniline(HM-A1). Organic light-emitting diodes (OLEDs) with 5% Pt(ptp)2:HM-A1 attain peak power efficiency of 61.2 lm/W, versus 40.8 lm/W for analogous devices employing the standard turquoise-blue phosphor bis[(4,6-difluorophenyl)-pyridinato-N,C2′](picolinato)iridium(III) (FIrpic). Devices with x% Pt(ptp)2:HM-A1 exhibit blue emission maxima (λmax∼480 nm) with monotonic increase in excimer/monomer intensity ratio at higher doping levels within 1%–10%, causing color shift toward green and less charge balance. This work represents a significant step toward optimizing future white OLEDs from the same phosphor via combination of low-doped and higher-doped or neat films.
A bright and compact source of polarization entangled photons (2007)

We present a source of polarization entangled photons that uses periodically poled potassium titanyl phosphate and interferometers based on polarization beam displacers to achieve stable operation with few critical alignments.
A Large-Scale Deep Architecture for Personalized Grocery Basket Recommendations (2020)

With growing consumer adoption of online grocery shopping through platforms such as Amazon Fresh, Instacart, and Walmart Grocery, there is a pressing business need to provide relevant recommendations throughout the customer journey. In this paper, we introduce a production within-basket grocery recommendation system, RTT2Vec, which generates real-time personalized product recommendations to supplement the user’s current grocery basket. We conduct extensive offline evaluation of our system and demonstrate a 9.4% uplift in prediction metrics over baseline stateof-the-art within-basket recommendation models. We also propose an approximate inference technique 11.6x times faster than exact inference approaches. In production, our system has resulted in an increase in average basket size, improved product discovery, and enabled faster user check-out.
SumBot: Summarize Videos Like a Human (2020)

Video currently accounts for 70% of all internet traffic and this number is expected to continue to grow. Each minute, more than 500 hours worth of videos are uploaded on YouTube. Generating engaging short videos out of the raw captured content is often a time-consuming and cumbersome activity for content creators. Existing ML- based video summarization and highlight generation approaches often neglect the fact that many summarization tasks require specific domain knowledge of the video content, and that human editors often follow a semistructured template when creating the summary (e.g. to create the highlights for a sport event). We therefore address in this paper the challenge of creating domain-specific summaries, by actively leveraging this editorial template. Particularly, we present an Inverse Reinforcement Learning (IRL)-based framework that can automatically learn the hidden structure or template followed by a human expert when generating a video summary for a specific domain. Particularly, we propose to formulate the video summarization task as a Markov Decision Process, where each state is a combination of the features of the video shots added to the summary, and the possible actions are to include/remove a shot from the summary or leave it as is. Using a set of domain-specific human-generated video highlights as examples, we employ a Maximum Entropy IRL algorithm to learn the implicit reward function governing the summary generation process. The learned reward function is then used to train an RL-agent that can produce video summaries for a specific domain, closely resembling what a human expert would create. Learning from expert demonstrations allows our approach to be applicable to any domain or editorial styles. To demonstrate the superior performance of our approach, we employ it to the task of soccer games highlight generation and show that it outperforms other state-of-the-art methods, both quantitatively and qualitatively.
A highly efficient form of the selenocysteine insertion sequence element in protozoan parasites and its use in mammalian cells (2007)

Selenoproteins are an elite group of proteins containing a rare amino acid, selenocysteine (Sec), encoded by the codon, UGA. In eukaryotes, incorporation of Sec requires a Sec insertion sequence (SECIS) element, a stem-loop structure located in the 3'-untranslated regions of selenoprotein mRNAs. Here we report identification of a noncanonical form of SECIS element in Toxoplasma gondii and Neospora canine, single-celled apicomplexan parasites of humans and domestic animals. This SECIS has a GGGA sequence in the SBP2-binding site in place of AUGA previously considered invariant. Using a combination of computational and molecular techniques, we show that Toxoplasma and Neospora possess both canonical and noncanonical SECIS elements. The GGGA-type SECIS element supported Sec insertion in mammalian HEK 293 and NIH 3T3 cells and did so more efficiently than the natural mammalian SECIS elements tested. In addition, mammalian type I and type II SECIS elements mutated into the GGGA forms were functional but manifested decreased Sec insertion efficiency. We carried out computational searches for both AUGA and GGGA forms of SECIS elements in Toxoplasma and detected five selenoprotein genes, including one coding for a previously undescribed selenoprotein, designated SelQ, and two containing the GGGA form of the SECIS element. In contrast, the GGGA-type SECIS elements were not detected in mammals and nematodes. As a practical outcome of the study, we developed pSelExpress1, a vector for convenient expression of selenoproteins in mammalian cells. It contains an SBP2 gene and the most efficient tested SECIS element: an AUGA mutant of the GGGA-type Toxoplasma SelT structure.
Nanoimprinting over topography and multilayer three-dimensional printing (2002)

We have developed a simple imprinting technique that allows patterning over a nonflat substrate without the need for planarization. In this process, a polymer film is spin coated onto the mold and then transferred to a patterned substrate by imprinting. By selecting polymers with different mechanical properties, either suspended structures over wide gaps or supported patterns on raised features of the substrate can be obtained with high uniformity. It is found that imprinting at a temperature well above the glass transition temperature (Tg) of the polymer causes the thin residue film between features to dewet from the mold, which can greatly simplify the subsequent pattern transfer process. Multilayer three-dimensional polymer structures have also been successfully fabricated using this new imprinting method. The yield and dimensional stability in the multilayer structure can both be improved when polymers with progressively lower Tg are used for different layers. Compared to existing techniques for patterning on nonflat substrates, the current method has a number of advantages, including simplicity, versatility, high resolution, and low pattern distortion.
Laser-based fundus camera for infrared angiography (1995)

A laser diode was integrated in a fundus camera to provide narrowband IR illumination for indocyanine green angiography. Carefully designed filter characteristics that made the camera efficient are discussed and compared to a typical non-laser-based fundus camera. The performance of the camera integrated into a digital imaging system was assessed optically and clinically. The system proved to be well suited for the diagnosis of choroidal disease, such as neovascularizations that are difficult to diagnose otherwise.
Recycling and Recovery Routes for Spent Hydroprocessing Catalyst Waste (2013)

This study investigates the recovery of Mo, V, and Ni metals from the industrial spent hydroprocessing catalyst. These catalysts are not viable to regenerate mainly due to the metal deposition. The study was carried out on industrial spent residue hydroprocessing (ARDS) catalysts that contained high levels of metals. In the extraction process, metals were recovered through pyrometallurgical and hydrometallurgical routes. The possibility of recycling of total spent catalyst (TSC) was studied using various steps such as deoiling, drying, grinding, sieving, and decoking. In the subsequent steps, the digested spent catalysts were treated with acid–base reactions in order to separate the various components of the spent catalyst. Using various leaching reaction conditions such as acid–base concentration, reaction pH in aqueous as well as organic mediums was studied. The metals were leached out in the solution while the alumina support was recovered as bulk solid in the form of boehmite. The recovered alumina is further treated hydrothermally and recovered as boehmite. Samples were characterized by surface area, pore volume, and pore size distribution measurements. Hence, recovery of valuable metals from the spent catalysts is an attractive option for their recycling and utilization. Therefore, TSC recovery is not only important from an environmental point of view but also very vital from an economic viewpoint.
Artificial redox enzymes. II. A computational chemistry study<sup>1</sup> (1992)

Abstract A computational chemistry study of the artificial redox enzyme synthesized by covalently attaching flavin to cyclodextrins explains some of its properties. Calculations indicate that the flavin moiety covalently attached to cyclodextrin is not within the cavity of cyclodextrin. This result is consistent with the UV‐vis spectrum of the artificial enzyme. The calculations also indicate hydrogen bonds formed between the carbonyl groups of the catalytic functionality and the hydroxyl groups of cyclodextrin play a role in their most stable conformation. This explains the observed overall stability of these artificial enzymes compared to riboflavin. Electrostatic energies and solvation energies play a major role in the stability of the hosts and the orientation of guests included within the artificial enzymes. The rates of oxidation of various thiols catalyzed by the artificial enzyme can be explained by the relative distances between the sulfur atom of the substrates and C(4a) of the flavin moiety.
Learning equivalence classes of Bayesian network structures (1996)

Approaches to learning Bayesian networks from data typically combine a scoring metric with a heuristic search procedure. Given aBayesian network structure, many of the scoring metrics derived in the literature return a score for the entire equivalence class to which the structure belongs. When using such a metric, it is appropriate for the heuristic search algorithm to searchover equivalence classes of Bayesian networks as opposed to individual structures. We present the general formulation of a search space for which the states of the search correspond to equivalence classes of structures. Using this space, anyoneofanumber of heuristic searchalgorithms can easily be applied. We compare greedy search performance in the proposed search space to greedy search performance in a search space for which the states correspond to individual Bayesian network structures. 1
Continuous-time optical neural network associative memory (1989)

A continuous-time optical neural network capable of executing a broad class of energy-minimizing neural net algorithms has been built. The network is a ring resonator comprising a saturable, two-beam amplifier that acts as an optical neuron array, two volume holograms that provide global network interconnectivity, and a linear, twobeam amplifier that provides sufficient gain to permit network oscillation. The network has been used as an associative memory to store and recall multiple, nonorthogonal visual images.
Purification and biological characterization of epitaxin, a fibroblast-derived motility factor for epithelial cells. (1994)

We have identified a motility factor in conditioned medium of human fibroblasts that stimulates the migration of HepG2 cells in the Boyden chamber assay. This factor, termed epitaxin, was purified to homogeneity by ammonium sulfate precipitation, hydrophobic interaction chromatography on phenyl-Sepharose, and a series of reverse phase high performance liquid chromatography. Under a nonreducing condition, purified epitaxin migrated as a 36-kDa band, and the biological activity was recovered from the area in the gel coinciding with this band. Purified epitaxin stimulates the motility of HepG2 cells in the concentrations above 1 ng/ml with half-maximal activity at 4.2 ng/ml, and its mode of action is mainly chemotactic. Epitaxin slightly stimulates DNA synthesis of HepG2 cells, while scatter factor/hepatocyte growth factor which also stimulates the motility of HepG2 cells showed a growth-inhibitory effect. Epitaxin increases the motility of a wide variety of epithelially derived tumor cell lines, but none of the tested fibroblast lines responded to epitaxin. These results define epitaxin as a novel fibroblast-derived factor that affects the migration, and possibly the invasion, of epithelially derived tumor cells.
Further Advances in the Development of Environmentally Acceptable Corrosion Inhibitors (1999)

Abstract The environmental fate of specialty chemicals used in petroleum recovery processes has received increased attention in recent years. Our laboratory has contributed to early advances in this field. This paper outlines further systematic studies. The influences of alkoxylation, starting amine type, and acid chain length on imidazoline properties were studied in addition to the properties of blends. The properties considered were corrosion inhibition, biodegradability, marine organism toxicity, octanol/water partitioning, and vapor pressure. A cross section of field test and application results is included.
Characterization of Polyclonal Antibodies to Preselected Domains of the Human Estrogen Receptor* (1989)

We have synthesized three peptides with sequences identical to the DNA-binding domain of the human estrogen receptor (ER). These peptides correspond to sequences from amino acids 201-215, 231-245, and 247-261. We have used these peptides to develop polyclonal antibodies to the DNA-binding domain of ER. Six positive antisera were obtained against these peptides, as determined by enzyme-linked immunosorbent assay. Three of these antisera recognized the functional form of ER, as determined by sucrose density gradient analysis. The antisera that recognized the native form of ER were then tested for their ability to cross-react with other steroid receptors and with ER from other species. No cross-reaction with the native progesterone, glucocorticoid, or androgen receptors was observed. The antisera cross-reacted with cytosolic ER from calf and rat uterine tissues as well as human breast cancer tissue. The antisera recognized ER in its monomeric (4S), dimeric (5S), and multimeric (8S) forms. These antisera were site specific, since the free peptides displaced ER binding to the antibodies. The antibodies also recognized the unoccupied ER, as demonstrated by sucrose density gradients and postlabeling analysis. Thus, we have obtained three site-specific antibodies that recognize the DNA-binding region of the ER. These antibodies should prove useful as structural probes for the analysis of receptor-DNA interactions and elucidation of the functional domains of ER.
Initial Evaluation of a Titration Appliance for Temporary Treatment of Obstructive Sleep Apnea (2012)

The titration appliance may be useful in assessing oral appliance treatment efficacy. When set to 70% of maximum protrusion, the titration appliance may provide immediate, temporary therapeutic benefit.
Compact replicate/transfer switch for field access bubble devices (1976)

A compact transfer/replicate switch has been developed which is also capable of bubble annihilaation. The switch utilizes a new 180 degree multi‐chevron corner adapted to a conventional T‐I propagation pattern (Figure 1) and permits two bit spacing of the minor loops on the access track resulting in minimum access time for any given data block. A two level version of the switch has been employed in a 64K bit block access chip design.1 The manipulation of the domains is accomplished in a fashion similar to an all chevron, one level switch previously introduced by other workers.2 The propagation margin of the minor loop at −25°, 25°, and 70°C is 16, 17, and 13 Oe respectively, for a drive field of 45 Oe at 100 kHz. The annihilation function overlaps the propagation margin completely over this temperature range. At −25°, 25°, and 70°C replicate‐in has 12, 13.5, and 10 Oe; and transfer‐out has 8, 14, and 9 Oe. All the switching functions have at least 40 degree margins.
A Novel Synthesis of Polyesters Containing Hexa-(tert-butylhydroquinone)cyclotriphosphazene (2000)

The majority of polyphosphazene material research has concentrated on the linear polymer configuration. However, this represents only one of three potential backbone configurations for phosphazenes. Linear polymers are formed either directly from phosphorus and nitrogen containing precursors or from the ring opening polymerization of hexachlorocyclotriphosphazene. Two other backbone structures can be formed from hexachlorocyclotriphosphazene cyclolinear and cyclomatrix. Cyclolinear are the least studied due to synthetic difficulty. Cyclomatrix polymers represent a more facile method for forming non-linear phosphazenes.
Model-based control for chemical-mechanical planarization (CMP) (2004)

The research described in this tutorial paper involves an effort for physical modeling and model-based sensing and control of CMP systems. A dynamic model of a rotational CMP process is developed, as well as simulation software. This dynamic model is used for feedback control design based on in-situ thickness measurements, as well as run-to-run control using in-line metrology. Simulation results of open-loop, feedback control, and combined feedback and run-to-run control are presented and compared. A multivariable LQ (linear quadratic) feedback controller was designed and showed improvement of within-wafer-nonuniformity (WFWNU) at the end of a run in simulation over existing open-loop control of a CMP process. It also showed the possibility of using feedback control as a means of end pointing the CMP process. Furthermore, a run-to-run (R2R) controller was designed and simulated. Additional improvement of WIWNU and tracking a desired average wafer thickness was obtained, showing the merits of a combined feedback / run-to-run control process.
