A programmable policy manager for conversational biometrics (2003)

Conversational Biometrics combines acoustic speaker verification with conversational knowledge verification to make a more accurate identity decision. To manage the added level of complexity that the multi-modal user recognition approach introduces, this paper proposes the use of verification policies ,i n the form of Finite State Machines, which can be used to program a policy manager. Once a verification policy is written, the policy manager interprets the policy on the fly, and at every turn in the session decides dynamically whether to accept the user, reject the user, or continue to interact and collect more data. The policy manager allows for any number of verification engines to be plugged-in, thereby adding to the flexibility of the framework. As a result, system developers have significant freedom to design user verification solutions, and a wide variety of applicationspecific, transaction-specific and user-specific constraints can be addressed using a generic system. The paper also describes a prototype implementation of a Conversational Biometrics solution with the proposed programmable policy manager.
Pro-Th1 Cytokines Promote Fas-Dependent Apoptosis of Immature Peripheral Basophils (2004)

Abstract We have previously characterized immature hemopoietic cells of the basophil lineage as a lin−c-kit− population, which responds to IL-3 by enhancing its histamine synthesis through histidine decarboxylase activation. Herein, we show both in vitro and in vivo that exposure to the pro-Th1 cytokines IL-12 and IL-18 promotes Fas-dependent apoptosis of these cells in the spleen. This conclusion was supported by the following findings: 1) A 24-h treatment with IL-12 plus IL-18 enhanced Fas expression and annexin staining among basophil precursor-enriched lin−c-kit− splenocytes. 2) Fas or Fas ligand deficiency in mutant mice abolished the inhibitory effect of IL-12 plus IL-18 on IL-3-induced histamine production. 3) The large spectrum inhibitor of the caspase cascade, benzyloxycarbonyl-Val-Ala-Asp fluoromethylketone, significantly reduced the effect of IL-12 plus IL-18. The inhibition of histamine production was mediated through NK cells, since it failed to occur upon stimulation of spleen cells from NK cell-deficient mice or after NK cell depletion. IL-12 plus IL-18 rendered NK cells cytotoxic against Fas-transfected target cells and promoted their production of IFN-γ and TNF-α, which are both essential for sensitizing histamine-producing cells to the Fas death pathway. This is the first evidence that pro-Th1 cytokines can promote apoptosis of immature peripheral histamine-producing cells, thus limiting Th2 immune responses. Comparable in vivo data as well as increased histamine production in the spleen of aged Fas-deficient lpr mice support its physiological relevance.
On the considerations for the design of an automated aircraft sheet metal component production loft generation system (2005)

In this paper an ambitious production loft generation system (PLGS) is created to incorporate innovative and unique features of aircraft sheet metal component (SMC) lofts meeting the stringent standards of aircraft industry owing to non-availability of suitable public domain software. This system is fully tested and validated with the support of the aircraft industry. It provides for automated blank layout generation based on surface models utilizing some unique algorithms and vector logics created through research and development over a period of 15 years taking into account the material properties, flow direction and plasticity and strives to eliminate post forming trimming operations by utilizing the databases of the aircraft industry. For the first time such a custom built system is created, which incorporates industrial process data and provides a host of processing options, together with various design cum production features like mould lines, joggles, bend relief, tooling holes, pilot holes, cut outs, chamfers/fillets, inspection angles etc. and displays features needed for quality assurance as essential ingredients. It has inbuilt, intelligent, high efficiency processing features such as the utilization of symmetry facilitating fractional processing of the SMC. This paper includes a brief account of various issues related to the chronology of design of the systems, implementation of the design options, intricacies of methods deployed, their efficacy and combinatorial suitability. Crucial ground breaking new algorithms relevant to the production features are also elucidated in this paper.

Chemostat Flow Cell System: An in vitro Model for the Evaluation of Antiplaque Agents (1994)

We developed an experimental in vitro model of dental plaque to assess the potential efficacy of antiplaque agents. The model used a chemostat, which provided a continuous source of 5 species of oral bacteria grown in an artificial "saliva-like" medium. This mixture was pumped through six flow cells, each containing two types of surfaces on which plaque formed and was subsequently measured. Formation of bacterial plaque on hydroxyapatite surfaces was assessed by measurement of the DNA and protein content of the plaque film. The amount of bacterial plaque formed on germanium surfaces was measured by attenuated total reflectance (ATR/FT-IR) spectroscopy. Plaque viability was also assessed by a fluorescent staining technique. The quantity of plaque formed on both types of surfaces gradually increased with the duration of flow (from 24 to 72 h) through the cells during a 72-hour experimental period. The flow cells were then pulsed with experimental treatment solutions for 30 s, twice daily. Parallel to results of human clinical studies, the model was capable of discriminating among water, a placebo mouthrinse, and an active antimicrobial mouthrinse formulation containing 0.03% triclosan. It therefore offers a valuable alternative to animal model testing and allows for more rapid evaluations under well-controlled experimental conditions.
Activity of cabozantinib in metastatic uveal melanoma: Updated results from a phase II randomized discontinuation trial (RDT). (2013)

9094 Background: MET and VEGF signaling are implicated in angiogenesis, invasion, and metastasis, and upregulation of MET as a consequence of GNAQ/GNA11 mutation has been implicated in uveal melanoma. Historical rates of median overall survival (OS) in patients (pts) with metastatic uveal melanoma range from 6-9 months (mos). A RDT evaluated activity and safety of cabozantinib, a MET and VEGFR2 inhibitor, in 9 tumor types including a metastatic melanoma cohort where 55% and 5% of pts experienced objective tumor regression and confirmed partial response, respectively (J. Clin. Oncol. 30, 2012 (suppl; abstr. 8531)). Here we report on the longer term followup of metastatic uveal melanoma pts enrolled to this cohort. Methods: Eligible pts were required to have progressive measurable disease per RECIST. Pts received cabozantinib at 100 mg po qd over a 12 wk Lead-in stage. Tumor response (mRECIST) was assessed q6 wks. Treatment ≥ wk 12 was based on response: pts with PR continued open-label cabozantinib, pts with SD were randomized to cabozantinib vs placebo, and pts with PD discontinued. Pts were followed for overall survival. Results: 23 of 77 pts enrolled in the melanoma cohort had the uveal subtype. Median age was 65 yrs; median prior regimens was 1 (range 0-5). Tumor mutation status was determined for 10/23 pts. 9/10 harbored either a GNAQ or GNA11 mutation, while GNA11 status was unknown for one pt. Pts had substantial tumor burden; median sum of the longest diameter of target lesions was 11.9 cm (range, 2-37.2). Median follow-up was 26.5 mos. (range 21.7-33.8). Median PFS from Study Day 1 was 4.8 mos. The estimate of PFS at month 6 (PFS6) was 41% and median OS was 12.6 mos. Most common Grade 3/4 AEs were HTN (13%), abdominal pain (9%), hypokalaemia (9%), hyperbilirubinaemia (9%) and increased lipase (9%). Conclusions: Cabozantinib is active in pts with metastatic uveal melanoma. Treatment with cabozantinib is associated with encouraging progression-free and overall survival. The safety profile of cabozantinib was comparable to that of other VEGFR TKIs. A randomized Phase 2 study is planned comparing cabozantinib to temozolomide plus dacarbazine in pts with uveal melanoma. Clinical trial information: NCT00940225.
A Novel Space-Vector Current Control Based on Circular Hysteresis Areas of a Three-Phase Neutral-Point-Clamped Inverter (2009)

This paper presents a novel space-vector current-control strategy for three-phase neutral-point (NP)-clamped inverters. The main task of this control technique is to force the actual current vector to reach the reference current vector. This original strategy consists in defining three circular hysteresis bands around the error vector. Then, according to the location of this error vector, a selection process of the next applied vector is used to minimize the error vector. The NP voltage is balanced by using the redundant inverter switching states. Simple lookup tables are required for area and sector detection, as well as for vector selection. The performance of the proposed control technique is demonstrated through simulation and experimental investigations.
Intracranial pressure and cerebral perfusion pressure in severe head injury. (1995)

Monitoring and management of intracranial pressure (ICP) are fundamental to modern neurotraumatology. Although never formally proven to independently improve outcome in prospective, randomized, placebo-controlled trials, there is such a predominance of indirect support for this modality that most neurotrauma protocols are impossible with-out its inclusion and ethical considerations virtually preclude placebo-controlled trials of its efficacy. In addition to the question of improving outcome, ICP monitoring is also useful in guiding the use of potentially harmful treatment modalities such as hyperventilation, mannitol, and barbiturates, and also provides important prognostic data. ICP monitoring provides information on the likelihood of cerebral herniation and allows calculation of the cerebral perfusion pressure (CPP). Although there is no constant threshold for herniation, the most commonly used treatment threshold is 20 to 25 mm Hg. In addition, ICP trends are indispensable in providing the earliest possible indication of critical intracranial mass effects when combined with other clinical indicators. CPP is the difference between mean arterial pressure and ICP. CPP is an important clinical indicator of cerebral blood flow (CBF). Cerebral autoregulation generally remains at least partially preserved after severe head injury, although the CPP value at which it is activated appears to be shifted upward. Therefore, maintaining adequate CBF appears to require using an elevated minimal CPP threshold when treating the injured brain. A generally accepted value of 70 mm Hg is suggested.

Auditory Context Awareness via Wearable Computing (1998)

We describe a system for obtaining environmental context through audio for applications and user interfaces. We are interested in identifying specific auditory events such as speakers, cars, and shutting doors, and auditory scenes such as the office, supermarket, or busy street. Our goal is to construct a system that is real-time and robust to a variety of real-world environments. The current system detects and classifies events and scenes using a HMM framework. We design the system around an adaptive structure that relies on unsupervised training for segmentation of sound scenes.
Embedding constraint satisfaction in deductive reasoning (2002)

The authors describe the Logos reasoning systems and present examples of its advantages. Logos merges two different problem-solving paradigms (constraint propagation and deductive reasoning) into a unified, declarative framework. Constraints are expressed in a declarative language and results of constraint propagation are maintained through a truth maintenance system. Constraint relaxation strategies are easily expressed as rules. Logos uses state descriptors to maintain transitions of constraint values and control constraint relaxation. This unified framework leverages the expressiveness of deductive reasoning with truth maintenance to enable structured control of constraint propagation.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Energy Release Rate Determination for Edge Delamination under Combined In-Plane, Bending and Hygrothermal Loading. Part I-Delamination at a Single Interface (1994)

Edge delamination in composite laminates subjected to combined in-plane, bending and hygrothermal loading is analyzed using a crack tip element approach. Classical laminated plate theory is utilized for the crack tip element formulation. Individual energy release rate components are found using a set of closed form equations derived from plate theory, plus the results from a single continuum analysis. For those cases where a linear elastic solution predicts a near-field oscillatory singularity, a new approach is used which allows a unique, physically meaningful value of fracture mode ratio to be defined.
FPGA implementation of stream cipher using Toeplitz Hash function (2014)

Hardware efficient stream ciphers and hash functions are widely used in cryptographic applications. The one-wayness and low hardware complexity of hash function make it a good candidate for authentication operation of crypto-systems. On the other hand, stream ciphers are being widely used in the domain of cryptology. Generally, these stream ciphers use static key stream for the crypto process. In this work, we propose a hash function based key generator and integrate the hash function based key generation with the RC4 stream cipher block so as to provide dynamic key to the RC4's encryption system thus realizing a robust security hardware prototype. The proposed method is designed for 5-bit hash key and stream cipher using Verilog HDL and simulated using Xilinx ISE 14.2 simulator. Further the design implementation has been done on the commercially available Xilinx Spartan 3E fg320-4 FPGA device. The excellence of the generated random key value by our proposed method is validated using the statistical tests proposed by National Institute of Standard and Technology (NIST).
Effective and adaptive technological solution to block spam E-mails (2016)

The internet E-mail infrastructure has become famous and widely used means of communication for personal, business and academic purposes just because it is fast, cheap and very efficient. People are using this E-mail infrastructure for their day-to-day work. The users are receiving many unwanted E-mails from the unknown senders. These unwanted E-mails are called as spam E-mails. In this paper technological solution for blocking spam E-mail is discussed. This technological solution consists of combination of origin based filters (OBF) and content based filters (CBF) which is adaptive in nature. The CBF Filter contains two components machine learning based classifier (MLC) and semantic similarity with edge based classifier (SSC). This technological solution is tested on the standard dataset such as Enron, LingSpam along with personal E-mail messages (PEM). The results empirically prove the strength of this solution.
Heterodyne double-channel polarimeter for mapping birefringence and thickness of flat glass panels (2006)

A new cross-polarized heterodyne optical technique is developed for two-dimensional (2D) simultaneous mapping of both birefringence and thickness variations in large flat glass panels commonly used in liquid-crystal displays (LCDs). Weak depolarization of a linearly polarized probe beam due to glass birefringence is detected by means of heterodyne mixing of the two cross-polarized and frequency shifted waves generated by Zeeman-type laser. Amplitude variations of the transmitted laser beam due to interference of the partial waves reflected from the both sides of a sample provide information about glass thickness. Measurements are being performed at the intermediate frequency of 2.3MHz, providing several orders of magnitude higher speed of data acquisition with respect to traditional polarimeters. That high speed of measurements makes it possible to perform quality assessment of LCD glass panels not only in few randomly chosen points as it was in common practice before but to obtain entire 2D maps of both birefringence and thickness variations with millimeter scale spatial resolution. The medium-scale prototype of the LCD glass inspection system is developed and tested. Design and performance of the prototype are described.
High Performance Volume Splatting for Visualization of Neurovascular Data (2006)

A new technique is presented to increase the performance of volume splatting by using hardware accelerated point sprites. This allows creating screen aligned elliptical splats for high quality volume splatting at very low cost on the GPU. Only one vertex per splat is stored on the graphics card. GPU generated point sprite texture coordinates are used for computing splats and per-fragment 3D-texture coordinates on the fly. Thus, only 6 bytes per splat are stored on the GPU and vertex shader load is 25% in comparison to applying textured quads. For eight predefined viewing directions, depth-sorting of the splats is performed in a pre-processing step where the resulting indices are stored on the GPU. Thereby, there is no data transfer between CPU and GPU during rendering. Post-classificative two dimensional transfer functions with lighting for scalar data and tagged volumes were implemented. Thereby, we focused on the visualization of neurovascular structures, where typically no more than 2% of the voxels contribute to the resulting 3D-representation. A comparison with a 3D-texture-based slicing algorithm showed frame rates up to 11 times higher for the presented approach on current CPUs. The presented technique was evaluated with a broad medical database and its value for highly sparse volume visualization is shown.

Enhancing Pt/C Catalysts for the Oxygen Reduction Reaction with Protic Ionic Liquids: The Effect of Anion Structure (2017)

Protic ionic liquids (ILs) have been recently studied as a potential approach to enhance oxygen reduction reaction (ORR) activity of carbon supported platinum catalysts (Pt/C) for application in polymer electrolyte membrane fuel cells. The high oxygen solubility in the ILs was suggested as one of the main reasons for the accelerated reaction rates. Because the nature of the anion of the IL has been associated with increased oxygen solubility, in this work we survey a number of ionic liquids with various anions to study this effect. While the search for direct correlation between the ORR activities and the oxygen solubilities does not produce any conclusive results, by contrast, the specific activity showed dependence on the availability of oxygenated species free Pt sites. This finding indicates that the inhibition of Pt oxidation and less adsorption of non-reactive species may also play an important role in the enhanced ORR activity. Moreover, the degree of IL coverage on the Pt surface was estimated using (bi)sulfate ions as an indicator. The surface coverage not only affected the ORR activity, but also the Pt dissolution process. This suggests that an optimal balance between activity and stability can be achieved on a partially covered Pt surface.
Synthesis of Poly[2,2′-(m-phenylene)-5,5′-bibenzimidazole] andPoly(2,5-benzimidazole) by Microwave Irradiation (2009)

A rapid way assisted by microwave irradiation was proposed to synthesize poly[2,2'-(m-phenylene)-5,5'-bibenzimidazole](PBI) and poly(2,5-benzimidazole)(ab-PBI).Synthesis of PBI in polyphosphoric acid is conducted for 20 h or even more.Under microwave irradiation,the polycondensations could be completed in polyphosphoric acid within 3 h from 3,3'-diaminobenzidine tetrahydrochloride(DAB·4HCl·2H2O) and isophthalic acid for PBI,and from 3,4-diaminobenzoic acids(DABA) for ab-PBI,respectively.The conditions for the polymerization including the power of microwave irradiation,temperature,heating time,and concentrations of the reactants in polyphosphoric acid were optimized.The inherent viscosity of the polymers in concentrated sulfuric acid at 30 °C was 0.9766 dL/g for PBI,and 0.6480 dL/g for ab-PBI,respectively.Characterization of the polymer products was made by nuclear magnetic resonance(1H NMR),Fourier transform infrared spectra(FTIR) and thermogravimetric analysis(TGA).
