Design and evaluation of laser spot illuminator for a laser projection engine design (2016)

An easily implementable illumination optical element enabling collection and redirection of multiple precollimated laser beams to be used as a laser spot illuminator (LSI) is proposed. Unlike the lenses, this element is free from any aberration and focusing/defocusing effects which may arise due to curved surfaces. The nonfocusing nature of beams reduces risk of the thermal instability at the target spot if compared with focused beam, especially for high brightness applications where multiple laser beams are used. Further, the illuminating spot is more uniform and pupil filling is higher which can help in the reduction of speckle contrast for imaging applications. In this research, we present two designs of LSI named biprism and sleek design, suitable for conventional grinding-polishing and molding methods of fabrication, respectively. It is shown that the proposed spot illuminator is suitable for conversion of lamp/LED-based projection engine design into a laser projector engine without any modification in its relay and imaging optics. Display performance parameters such as efficiency and uniformity across the modulator plane are reported and found acceptable for the projection engine designs using light tunnels as well as lenslet arrays for homogenization. Further, a prototype of a biprism laser illuminator for 2×4 laser arrays has been fabricated and evaluated to demonstrate its manufacturability.
Frequency-selective surfaces analyzed by THz-time-domain spectroscopy (2002)

The transmission and phase shift characteristics of dichroic high-pass and cross-shaped grid bandpass filters were measured in the region from 0.1 to 1.5 THz with an electro-optic (eo) sampling THz-time-domain spectrometer. Good agreement with applied transmission theories is found. In this spectral region, which is difficult to access by conventional means, the knowledge of the frequency response of these frequency-selective surfaces (FSS) is important for applications in frequency mixing and multiplying experiments. Alternatively, FSS's permit temporal shaping of THz pulses for frequency selective ultrafast experiments in the THz range.

Injection of a streaming plasma into a mirror machine (1973)

The axial injection of a supersonically streaming plasma beam into a mirror machine is investigated experimentally. The object of the experiment is to obtain qualitative and quantitative data on the injection and trapping processes and in particular the transition from supersonic to subsonic flow and attendant shock formation. It is shown that for a mirror ratio of 3.3 and for a peak mirror field in excess of 3 kG, a shock is formed in the downstream mirror and results in increased density and temperature confinement time within the mirror machine. The helium plasma beam is produced by a conical theta-pinch gun driven by a capacitor bank with a stored energy of 2.5 kJ. Measurements are made of the plasma density, temperature and streaming velocity.
Polysaccharide-Based Polyelectrolyte Complex Nanoparticles from Chitosan, Heparin, and Hyaluronan (2009)

The formation of polyelectrolyte complex nanoparticles (PCN) was investigated at different charge mixing ratios for the chitosan-heparin (chi-hep) and chitosan-hyaluronan (chi-ha) polycation-polyanion pairs. The range of 0.08-19.2 for charge mixing ratio (n(+)/n(-)) was examined. The one-shot addition of polycation and polyanion solutions used for the formation of the PCN permitted formation of both cationic and anionic particles from both polysaccharide pairs. The influence of the charge mixing ratio on the size and zeta potential of the particles was investigated. The morphology and stability of the particles when adsorbed to surfaces was studied by scanning electron microscopy (SEM). For most conditions studied, colloidally stable, nonstoichiometric PCN were formed in solution. However, PCN formation was inhibited by flocculation at charge mixing ratios near 1. When adsorbed to surfaces and dried, some formulations resulted in discrete nanoparticles, while others partially or completely aggregated or coalesced, leading to different surface morphologies.
Design, Synthesis, and Evaluation of <i>N</i>-Acyl Modified Sialic Acids as Inhibitors of Adenoviruses Causing Epidemic Keratoconjunctivitis (2009)

The adenovirus serotype Ad37 binds to and infects human corneal epithelial (HCE) cells through attachment to cellular glycoproteins carrying terminal sialic acids. By use of the crystallographic structure of the sialic acid-interacting domain of the Ad37 fiber protein in complex with sialyllactose, a set of N-acyl modified sialic acids were designed to improve binding affinity through increased hydrophobic interactions. These N-acyl modified sialic acids and their corresponding multivalent human serum albumin (HSA) conjugates were synthesized and tested in Ad37 cell binding and cell infectivity assays. Compounds bearing small substituents were as effective inhibitors as sialic acid. X-ray crystallography and overlays with the Ad37-sialyllactose complex showed that the N-acyl modified sialic acids were positioned in the same orientation as sialic acid. Their multivalent counterparts achieved a strong multivalency effect and were more effective to prevent infection than the monomers. Unfortunately, they were less active as inhibitors than multivalent sialic acid.
Early Seizure Detection (2001)

For patients with medically intractable epilepsy, there have been few effective alternatives to resective surgery, a destructive, irreversible treatment. A strategy receiving increased attention is using interictal spike patterns and continuous EEG measurements from epileptic patients to predict and ultimately control seizure activity via chemical or electrical control systems. This work compares results of seven linear and nonlinear methods (analysis of power spectra, cross-correlation, principal components, phase, wavelets, correlation integral, and mutual prediction) in detecting the earliest dynamical changes preceding 12 intracranially-recorded seizures from 4 patients. A method of counting standard deviations was used to compare across methods, and the earliest departures from thresholds determined from non-seizure EEG were compared to a neurologist's judgement. For these data, the nonlinear methods offered no predictive advantage over the linear methods. All the methods described here were successful in detecting changes leading to a seizure between one and two minutes before the first changes noted by the neurologist, although analysis of phase correlation proved the most robust. The success of phase analysis may be due in part to its complete insensitivity to amplitude, which may provide a significant source of error.
Hot air leveled tin: solderability and some related properties (2003)

Pure hot-air-leveled tin coatings on copper alloy substrates were stored at room temperature for up to four years and then tested for solderability. The solderability of these aged coatings was found to be very good. The intermetallic compound growth rates at lower temperatures were determined to be considerably lower than in electroplated tin coatings. This was attributed to the very large grain size of the tin layer. It was demonstrated that intermetallic growth is significant at the grain boundaries only, which accounts for the overall low growth rates. The whiskering tendency of hot-air-leveled coatings was assessed using tests designed to promote rapid whisker growth. No whiskers or whisker-related features were detected. The grain structure of hot-air-leveled tin, particularly the very large grain size, is the most likely reason for the absence of whiskers.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Recent progress with oxazolidinone antibacterial agents (2000)

The oxazolidinone class of antibiotics represents a promising advance in the battle against multiply resistant Gram-positive bacterial infections. Numerous companies have been involved in this area of research and Pharmacia has recently brought the first member of this class, linezolid (Zyvox®), to market for the treatment of sensitive and resistant Gram-positive bacterial infections. During the last few years, advancements have been made by several firms in expanding oxazolidinone SAR as well as the spectrum of activity to include the fastidious Gram-negative organisms Haemophilus influenzae and Moraxella catarrhalis.
Cloning and molecular characterization of a copper chaperone gene (HbCCH1) from Hevea brasiliensis (2011)

The cDNA encoding a copper chaperone, designated as HbCCH1, was isolated from Hevea brasiliensis . HbCC1 was 589 bp long containing a 261 bp open reading frame encoding a putative protein of 86 amino acids, flanked by a 103 bp 5’UTR and a 225 bp 3’UTR. The predicted molecular mass of HbCCH1 was 9.2 kDa, with an isoelectric point (pI) of 5.13. The HbCCH1 share the conserved N-terminal metalbinding domain (MXCXXC) and a lysine-rich C-terminus. Reverse transcriptase polymerase chain reaction (RT-PCR) analysis revealed that HbCCH1 was constitutively expressed in all the tested tissues. HbCCH1 transcripts were accumulated at relatively low levels in the flower, bud and leaves, while HbCCH1 transcripts were accumulated at relatively high levels in the latex. The transcription of HbCCH1 in the latex was induced by jasmonate. Key words : Copper chaperone, Hevea brasiliensis, latex.
Frequency- and depth-dependent compensation of ultrasonic signals (1988)

The resolution in ultrasonic images decreases with depth when using traditional time-gain compensation (TGC) of the received signal. To reduce this effect, both frequency-dependent and depth-dependent compensation is introduced. A time-varying digital filtering method is presented for this purpose, which is based on Wiener filtering. Images obtained from a simulated tissue equivalent are presented and the frequency-compensated images are compared to conventional TGC-compensated images. It is shown that the improvement in resolution using frequency-dependent compensation is considerable when the signal-to-noise ratio in the received signal is high.
Inverse Elastic Cloth Design with Contact and Friction (2016)

Physically based cloth modeling is classically achieved through a trial and error process. The rest (undeformed) configuration of the cloth, often represented as a 2D pattern assembly, is edited geometrically and adjusted iteratively depending on the feedback provided by a static cloth simulator, which predicts the deformed 3D shape under gravity and contacts. Matching a reference 3D shape while keeping the time of the modeling process reasonable is thus difficult , unless the user possesses advanced skills in real cloth tailoring. In contrast, in this paper we investigate a new, inverse strategy for modeling realistic cloth intuitively. Our goal is to take as input a target (deformed) 3D shape, and to interpret this configuration automatically as a stable equilibrium of a cloth simulator, by retrieving the unknown rest shape. In the presence of gravity and frictional contact, such an inverse problem formulates as an ill-posed nonlinear system subject to nonsmooth constraints. To select and compute a plausible solution, we design an iterative two-step solving process. In a first step, contacts are reduced to frictionless bilateral constraints, and starting from an as-flat-as possible pose, a unique rest pose is retrieved using the adjoint method on a regularized energy. The second step modifies this rest pose so as to project bilateral forces onto the admissible Coulomb friction cone, for each contact. We show that our method converges well in most cases towards a plausible rest configuration, and demonstrate practical inversion results on various cloth geometries modeled by an artist.

A 100X magnification, ± 2.5° field of view micro-concentrating optical system has been developed for a microsystems-enabled photovoltaic (MEPV) prototype module using 250 µm diameter multi-junction "stacked" PV cells.
Dibenzo‐fused seven‐membered nitrogen heterocycles by a tandem reduction‐lactamization reaction (2006)

Abstract magnified image Efficient syntheses of dibenz[ b,f ][1,4]oxazepin‐11(10 H )‐one, 5,10‐dihydro‐11 H ‐dibenzo[ b,e ][1,4]‐diazepin‐11‐one and 5,11‐dihydro‐6 H ‐dibenz[ b,e ]azepin‐6‐one are described using a tandem reductionlactamization sequence. Precursors for these ring systems are available in 1‐3 steps using nucleophilic aromatic substitution and Ullmann coupling methodology. Direct reduction‐lactamization of these compounds using iron powder in acetic acid at 115° affords the target heterocycles in ≥90% yield.
A monograph of the genus Barringtonia (Lecythidaceae) (1967)

A brief history is given on the circumscription and subdivision of Lecythidaceae and the position of Barringtonia. All aspects, also of auxiliary disciplines point to affinity with Myrtaceae but warrant separate family status. The conviction is that only one family is concerned, not two, or even three, as Knuth proposed.\nThe subdivision of Lecythidaceae appears to meet with great difficulty. It does not seem to be possible to divide the family in tribes which would be restricted to the New and Old Worlds respectively, affinities running transoceanic.\nIn the present revision of the genus Barringtonia 39 species are distinguished, 3 of which have one or a few new subspecies, varieties, or forms; three species are newly described. A survey is given of the morphological characters, their variation, and systematical value.\nGreat attention is given to the seed structure and blastogeny which could be studied in two species. Various dubious or erroneous former statements on the peculiar embryo could be straightened out. The mature embryo is almost unique among Angiosperms because it is a solid body, provided with a spiral of small scales, but without cotyledons as usually understood. After germination this spiral is continued, first with cataphylls and finally with normal leaves.\nA similar structure is possibly found in other genera of Lecythidaceae; it appears highly desirable that embryogeny of all genera be studied, to ascertain its systematical importance.\nTwo sections based on the calyx structure can be distinguished. This coincides with former generic distinction. Barringtonia sens. str. has initially a closed calyx which later disrupts into pseudolobes or opens circumscissile and Stravadium has a calyx which is open from the beginning. Within these sections eleven smaller groups of mutually allied species are present but they can only vaguely be defined and do not represent taxa.\nAll species were examined palynologically and appeared to belong to eight pollen types, each comprising one or mor
Hemichannels in cardiomyocytes open transiently during ischemia and contribute to reperfusion injury following brief ischemia (2007)

The aim of this study was to investigate changes in hemichannel activity during in vitro simulated ischemia [oxygen-glucose deprivation (OGD)] and the contribution of hemichannels to ischemia-reperfusion injury in rat neonatal cardiomyocytes. Dye uptake assays showed that hemichannels opened as OGD progressed, peaking after 1 h, and then closed, returning to the pre-OGD state after 2 h of OGD. The increase in dye uptake after 1 h of OGD was inhibited by hemichannel blockers (lanthanum chloride and a connexin 43 mimetic peptide, Gap26). During OGD, intracellular Ca(2+) concentration ([Ca(2+)](i)) began to increase after 1 h and reached several micromolar after 2 h. After 1 h of OGD, Gap26 inhibited the increases in hemichannel activity and [Ca(2+)](i). In contrast, dantrolene [an endo(sarco)plasmic reticulum Ca(2+) release inhibitor] suppressed the increase in [Ca(2+)](i), but not in hemichannel activity. After 2 h of OGD, the combined administration of 2',4'-dichlorobenzamil and dantrolene reduced [Ca(2+)](i) to <1 microM and increased hemichannel activity to the level attained after 1 h of OGD. Simulated ischemia-reperfusion, induced by 1 h of OGD followed by 2 h of recovery, reduced cell viability to 54% of the control level. The addition of Gap26 to OGD medium improved viability to 80% of the control level. In conclusion, this study demonstrated that 1) hemichannels open transiently during OGD, 2) closure of hemichannels, but not their opening, is regulated by an increase in [Ca(2+)](i) during OGD, and 3) open hemichannels contribute to cell injury during recovery from OGD.
Advances in brain imaging of neuropathic pain (2008)

Application of the techniques of brain imaging plays a very important role in the study of structural and functional reorganization in patients with neuropathic pain. However, a unique "pain matrix" has not been defined. Future studies should be conducted using a prospective longitudinal research design, which would guarantee the control for many confounding factors.
The Splog Detection Task and A Solution Based on Temporal and Link Properties. (2006)

Spam blogs (splogs) have become a major problem in the increasingly popular blogosphere. Splogs are detrimental in that they corrupt the quality of information retrieved and they waste tremendous network and storage resources. We study several research issues in splog detection. First, in comparison to web spam and email spam, we identify some unique characteristics of splog. Second, we propose a new online task that captures the unique characteristics of splog, in addition to tasks based on the traditional IR evaluation framework. The new task introduces a novel time-sensitive detection evaluation to indicate how quickly a detector can identify splogs. Third, we propose a splog detection algorithm that combines traditional content features with temporal and link features that are unique to blogs. Finally, we develop an annotation tool to generate ground truth on a sampled subset of the TREC-Blog dataset. Initial experiments based on this ground truth set show promising results. 1.

Abnormal somatosensory homunculus in dystonia of the hand (1998)

Abnormalities of the sensory system have been proposed as causative factors for dystonia By mapping the human cortical hand somatosensory area of 6 patients with focal dystonia of the hand, we found an abnormality of the normal homuncular organization of the finger representations in the primary somatosensory cortex (S1). Although a remote antecedent event or even a developmental anomaly cannot entirely be ruled out, our findings may support the concept that abnormal plasticity is involved in the development of dystonia.
Deep Video Prediction Network-Based Inter-Frame Coding in HEVC (2020)

In this paper, we propose a novel Convolutional Neural Network (CNN) based video coding technique using a video prediction network (VPN) to support enhanced motion prediction in High Efficiency Video Coding (HEVC). Specifically, we design a CNN VPN to generate a virtual reference frame (VRF), which is synthesized using previously coded frames, to improve coding efficiency. The proposed VPN uses two sub-VPN architectures in cascade to predict the current frame in the same time instance. The VRF is expected to have higher temporal correlation than a conventional reference frame, and, thus it is substituted for a conventional reference frame. The proposed technique is incorporated into the HEVC inter-coding framework. Particularly, the VRF is managed in a HEVC reference picture list, so that each prediction unit (PU) can choose a better prediction signal through Rate-Distortion optimization without any additional side information. Furthermore, we modify the HEVC inter-prediction mechanisms of Advanced Motion Vector Prediction and Merge modes adaptively when the current PU uses the VRF as a reference frame. In this manner, the proposed technique can exploit the PU-wise multi-hypothesis prediction techniques in HEVC. Since the proposed VPN can perform both the video interpolation and extrapolation, it can be used for Random Access (RA) and Low Delay B (LD) coding configurations. It is shown in experimental results that the proposed technique provides -2.9% and -5.7% coding gains, respectively, in RA and LD coding configurations as compared to the HEVC reference software, HM 16.6 version.
Murine Sarcoma Virus Gene Expression: Transformants Which Express Viral Envelope Glycoprotein In The Absence Of The Major Internal Protein And Infectious Particles (1974)

Expression of the major internal protein and the envelope glycoprotein of murine C-type viruses in focus-derived lines of normal rat kidney cells infected with Kirsten murine sarcoma virus was measured by radioimmunoassay. Of the clones selected, which do not produce virus particles or the major viral structural protein, approximately half express the viral envelope glycoprotein at concentrations found in productively infected cells. Expression of the envelope glycoprotein did not appear to alter significantly the properties of the transformed cells in culture.
