Pure delay effects on speech quality in telecommunications (1991)

The effect of transmission delay on speech quality in telecommunications is described, with human factors such as conversational mode and the talker's knowledge of the cause of delay taken into account. Objective quality estimation methods for delay effects are proposed, and these methods are applied in an actual communications network. In connection with delay perception in a telephone conversation, the assumption was verified that a talker expects a particular response time from a partner, and that delay that is outside this expectation time window is noticed. Taking this information into account, a subjective conversational experiment is controlled by six kinds of tasks by varying the temporal characteristics. Thus, a subjective assessment of delay effects is obtained by laboratory tests in relation to the detectability threshold, opinion rating, and conversational efficiency. Objective quality measures for each test were defined as a linear combination of temporal parameters that correspond closely to subjective qualities.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Multilayer antenna arrays for environmental sensing applications (2010)

Array antennas are used extensively in remote sensing applications, where a highly directive beam is needed to scan a particular area of interest on the surface of the earth. The research presented here focuses on the design of different microstrip patch antenna arrays to be used in environmental sensing applications in the X and Ka frequency bands, such as measurements in Snow and Cold Land Processes (SCLP) to detect snow accumulation, snow melt, etc. The goal of this research is to produce highly integrated, low loss, and compact size antenna arrays, while maintaining low power consumption. Multilayer organic (MLO) System-on-a-Package (SOP) technology, using laminates such as Liquid Crystal Polymer (LCP) and RT/Duroid®, provides a lightweight and low cost 3D solution for the fabrication of the antenna arrays. \nThe elements of the antenna arrays are rectangular patches. Two feeding mechanisms, aperture coupling and via feed, were implemented and compared. For the RF distribution network and interconnects, a corporate feed approach was used with reactive T-junctions, Wilkinson dividers, or both, for power division. The feed networks were designed using microstrip. The basic multilayer antenna array design consists of 3 layers of cladded laminate material. The metal layers are as follows: 1) patch antennas, 2) ground plane, 3) feed network, and 4) surface-mount components. The surface mount components would include LNA, PA, TR switch and phase shifter.
Solar‐thermochromism of Pseudocrystalline Nanodroplets of Ionic Liquid–Ni<sup>II</sup> Complexes Immobilized inside Translucent Microporous PVDF Films (2008)

Translucent composite films of poly(vinylidene fluoride), ionic liquid, and nickel complexes are successfully fabricated using thermal modulation of dissolution, casting, and drying. These films exhibit high stability in ambient storage and reversible thermochromic responses in air at temperatures achievable under sunlight, promising intelligent windows for controlling solar heat entering the built environment.
The Flow of Gases in Pipes at Low Pressures (1946)

Data are presented on the flow of air at low pressures in copper pipes of radius 0.795 and 1.30 cm; iron pipes of radius 2.64, 5.12, and 10.1 cm; and for hydrogen in a copper pipe of radius 1.30 cm. Data are also given for the resistance to flow of air in 1½- and 3-inch nominal pipe size elbows, for 1½-inch Kinney bellows valves, and for short sections of 1-inch nominal pipe size iron pipe connecting large gas chambers. The data on straight iron and copper pipes, together with the data from the literature on glass capillaries, are correlated by the introduction of a correction factor F in Poiseuille's equation. F is correlated graphically in terms of a dimensionless group representing the ratio of mean free path to pipe radius, with separate curves for iron pipe and for copper and glass pipes or capillaries.

Some like it hot - visual guidance for preference prediction (2016)

For people first impressions of someone are of determining importance. They are hard to alter through further information. This begs the question if a computer can reach the same judgement. Earlier research has already pointed out that age, gender, and average attractiveness can be estimated with reasonable precision. We improve the state of-the-art, but also predict - based on someone's known preferences - how much that particular person is attracted to a novel face. Our computational pipeline comprises a face detector, convolutional neural networks for the extraction of deep features, standard support vector regression for gender, age and facial beauty, and - as the main novelties - visual regularized collaborative filtering to infer interperson preferences as well as a novel regression technique for handling visual queries without rating history. We validate the method using a very large dataset from a dating site as well as images from celebrities. Our experiments yield convincing results, i.e. we predict 76% of the ratings correctly solely based on an image, and reveal some sociologically relevant conclusions. We also validate our collaborative filtering solution on the standard MovieLens rating dataset, augmented with movie posters, to predict an individuals movie rating. We demonstrate our algorithms on howhot.io which went viral around the Internet with more than 50 million pictures evaluated in the first month.

Fucosyltransferase 8 as a functional regulator of nonsmall cell lung cancer (2012)

The up-regulation of fucosyltransferase 8 (FUT8), the only enzyme catalyzing α1,6-fucosylation in mammals, has been observed in several malignant cancers including liver, ovarian, thyroid, and colorectal cancers. However, the pathological role and the regulatory mechanism of FUT8 in cancers remain largely unknown. In the current study, we report that the expression of FUT8 is up-regulated in nonsmall cell lung cancer (NSCLC) and correlates with tumor metastasis, disease recurrence, and poor survival in patients with NSCLC. Knocking down FUT8 in aggressive lung cancer cell lines significantly inhibits their malignant behaviors including in vitro invasion and cell proliferation, as well as in vivo metastasis and tumor growth. The results of glycoproteomic and microarray analyses show that FUT8 globally modifies surface antigens, receptors, and adhesion molecules and is involved in the regulation of dozens of genes associated with malignancy, suggesting that FUT8 contributes to tumor progression through multiple mechanisms. Moreover, we show that FUT8 is up-regulated during epithelial-mesenchymal transition (EMT), a critical process for malignant transformation of tumor, via the transactivation of β-catenin/lymphoid enhancer-binding factor-1 (LEF-1). These results provide a model to illustrate the relation between FUT8 expression and lung cancer progression and point to a promising direction for the prognosis and therapy of lung cancer.
Measurement of gaseous oxygen using diode laser spectroscopy (1987)

A commercial diode laser emitting at ∼761 nm has been used to detect the absorption of individual rotational lines of the A band of atmospheric oxygen. An output signal that is proportional to the O2 partial pressure is extracted using derivative spectroscopy. The method allows measurement of O2 pressure with an uncertainty of ±1.3% of full scale (760 Torr) using a 1-ms time constant.
Unitary root-MUSIC technique for uniform circular array (2004)

In this paper, unitary root-MUSIC algorithm for direction of arrival estimation is proposed for uniform circular array. Uniform circular array provides uniform performance in any direction and simultaneous azimuth and elevation angle estimates. The proposed algorithm has low computational complexity because eigenvalue decomposition for real number may be used. It also provides low variance estimates because the number of observations is doubled in comparison to conventional MUSIC algorithm. Also, a robust extension to the method is introduced based on multivariate extensions of nonparametric statistics. It gives highly reliable results in the face of heavy-tailed noise and interference. The additional computational cost is negligible.
Model peptide studies of sequence repeats derived from the intracrystalline biomineralization protein, SM50. II. Pro,Asn-Rich tandem repeats (2000)

In the biomineralization process, a number of Pro-rich proteins participate in the formation of three-dimensional supramolecular structures. One such protein superfamily, the Pro,Gly-rich sea urchin intracrystalline spicule matrix proteins, form protein-protein supramolecular assemblies that modify the microstructure of the inorganic mineral phase (calcite) within embryonic sea urchin spicules and adult sea urchin spines. These proteins represent a useful model for understanding Pro sequence usage and the resulting generation of extended or "open" structures for protein-protein and/or protein-crystal recognition. In the sea urchin spicule matrix protein, SM50 (Strongylocentrotus purpuratus), there exists an unusual 20-residue Pro,Asn-containing repeat, &bond;PNNPNNPNPNNPNNPNNPNPbond which links the upstream 15-residue C-terminal domain and the downstream 211-residue beta-spiral repeat domain. To define the structural preferences of this 20-residue repeat, we created a 20-residue N- and C-terminal "capped" peptidomimetic of this sequence. Using far-uv CD dichroism, CH(alpha) and alpha-(15)N conformational shifts, (3)J(NH-CHalpha) coupling constants, sequential d(NN(i, i + 1)) rotating frame nuclear Overhauser effect connectivities, d(alphaN(i, i + 1))/d(NN(i, i + 1)) intensity ratios, amide temperature shift coefficients, amide solvent exchange, and simulated annealing refinement protocols, we have determined that this 20-residue repeat motif adopts an extended "twist" structure consisting of turn- and coil-like regions. These findings are consistent with previous studies, which have shown that Pro-rich tandem repeats adopt extended, flexible structures in solution. We hypothesize that this 20-residue repeat may fulfill the role of a mineral-binding domain, a protein-protein docking domain, or as an internal "molecular spacer" for the SM50 protein during spicule biocomposite formation.
Antigenicity and immunogenicity of multiple antigen peptides (MAP) containing <i>P. vivax </i>CS epitopes in <i>Aotus</i> monkeys (1997)

Using linear synthetic peptides corresponding to the Plasmodium vivax circumsporozoite (CS) protein of the common type, we have identified several T and B-cell epitopes recognized by human individuals. Three T-cell epitopes studied (p6) from the amino, (p11) from the central and (p25) from the carboxyl regions, were widely recognized by lymphocytes of immune donors. A series of six peptides, in addition to p11, representing the central repeat domain of the CS(p11-p17) protein were used in ELISA assays to map the B-cell epitopes of this region. P11 was the peptide most frequently recognized by sera containing antibodies to the homologous CS protein as determined by IFAT. The sequences corresponding to peptides p6, p11 and P25 as well as that representing a universal T-cell epitope derived from the tetanus toxin were used to assemble eight different Multiple Antigen Peptides (MAP). The immunogenicity of these MAP was analysed in Aotus monkeys. Groups of two animals were immunized with each MAP and both antibody response, T-lymphocyte proliferation and in vitro gamma-IFN production were evaluated. Two MAPs containing the same B-cell epitope and either a promiscuous CS-protein derived T-cell epitope (p25) or the tetanus toxin epitope (p-tt30) proved to be the most immunogenic and induced high levels of anti-peptide antibodies that recognized the native protein. Except for animals immunized with MAP VII, there was no correlation between antibody levels, lymphocyte proliferation or gamma-IFN production in vitro. The broad recognition of these epitopes by individuals which had been exposed to malaria, the capacity of these MAPs to induce antibodies, recognize the cognate protein, and in vitro gamma-IFN production encourages further analyses of the potential of these proteins as malaria vaccine candidates for human use.
MO‐FF‐A1‐01: Fluoroscopic Verification of Intensity‐Modulated Rotational Arc Therapy Delivery (2009)

Purpose : Intensity modulated rotational arc technique requires verification of leaf positions, gantry angle and dose rate in the entire arc. This study shows how to achieve this with a detailed verification of Varian RapidArc using a fluoroscopic electronic portal imaging device (EPID). Materials and Methods : Three Rapid Arc plans (prostate 1, whole pelvis 1, and head and neck 1) are delivered on a Triology linac (Varian Medical Systems, CA). During delivery, approximately 600 fluoroscopic portal images are acquired (∼8 images/s) per arc with a PV‐aS1000 EPID, without use of secondary phantoms or blocks. Each leaf position of each gantry angle is calculated from the acquired EPID images offline. Gantry angle information of each portal image is acquired from the dynalog file generated during beam delivery. Leaf positions from the dynalog file are compared to scheduled positions from the DICOM RT plan file. Results : Online EPID image acquisition of Rapid Arc delivery is prompt, involving extension of the EPID system and beam delivery time. The measurement error depends on the displacement of EPID system relatively to the center of rotation, which is only 1mm–1.5 mm. Offline analyses show the accuracy of leaf positions for static leaf and gantry field are better than 1 mm. More than 98.5% of leaf sequences exhibit less than 3mm deviations, 83 % show 2mm and 56% for 1mm. Conclusions : Position of each leaf of each gantry angle for Rapid Arc delivery is verified within 1 mm accuracy with fluoroscopic portal images. Use of fluoroscopic EPID images can be considered as a practical QA tool for the verification of the Rapid Arc delivery. This study is partially supported by Varian Medical Systems.
Motion planning for controllable systems without drift (2002)

A general strategy for solving the motion planning problem for real analytic, controllable systems without drift is proposed. The procedure starts by computing a control that steers the given initial point to the desired target point for an extended system, in which a number of Lie brackets of the system vector fields are added. Using formal calculations with a product expansion relative to P. Hall basis, another control is produced that achieves the desired result on the formal level. This provides an exact solution of the original problem if the given system is nilpotent. For a general system, an iterative algorithm is derived that converges very quickly to a solution. For nonnilpotent systems which are feedback nilpotentizable, the algorithm, in cascade with a precompensator, produces an exact solution. Results of simulations which illustrate the effectiveness of the procedure are presented.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Ly6d marks the earliest stage of B-cell specification and identifies the branchpoint between B-cell and T-cell development (2009)

Common lymphoid progenitors (CLPs) clonally produce both B- and T-cell lineages, but have little myeloid potential in vivo. However, some studies claim that the upstream lymphoid-primed multipotent progenitor (LMPP) is the thymic seeding population, and suggest that CLPs are primarily B-cell-restricted. To identify surface proteins that distinguish functional CLPs from B-cell progenitors, we used a new computational method of Mining Developmentally Regulated Genes (MiDReG). We identified Ly6d, which divides CLPs into two distinct populations: one that retains full in vivo lymphoid potential and produces more thymocytes at early timepoints than LMPP, and another that behaves essentially as a B-cell progenitor.
Enhanced Fluorescence Emission and Singlet Oxygen Generation of Photosensitizers Embedded in Injectable Hydrogels for Imaging-Guided Photodynamic Cancer Therapy (2017)

Benefiting from their inherent localized and controlled release properties, hydrogels are ideal delivery systems for therapeutic drugs or nanoparticles. In particular, applications of hydrogels for the delivery and release of photoresponsive drugs or nanoparticles are receiving increasing attention. However, the effect of the hydrogel matrix on the fluorescence emission and singlet oxygen generation efficiency of the embedded photosensitizers (PSs) has not been clarified. Herein, meso-tetrakis(1-methylpyridinium-4-yl)porphyrin (TMPyP) as a water-soluble PS was encapsulated into an injectable hydrogel formed by glycol chitosan and dibenzaldehyde-terminated telechelic poly(ethylene glycol). Compared to free TMPyP solution, the TMPyP encapsulated in the hydrogel exhibits three distinct advantages: (1) more singlet oxygen was generated under the same laser irradiation condition; (2) much longer tumor retention was observed due to the low fluidity of the hydrogel; and (3) the fluorescence intensity of TMPyP was significantly enhanced in the hydrogel due to its decreased self-quenching effect. These excellent characteristics lead to remarkable anticancer efficacy and superior fluorescence emission property of the TMPyP-hydrogel system, promoting the development of imaging-guided photodynamic therapy.

Fiber core mode leakage induced by refractive index variation in high-power fiber laser (2017)

This paper presents an investigation of specific optical fiber core mode leakage behavior that occurs in high-power double-clad fiber lasers as a result of thermally-induced refractive index variations. A model of the power transfer between the core modes and the cladding modes during thermally-induced refractive index variations is established based on the mode coupling theory. The results of numerical simulations based on actual laser parameters are presented. Experimental measurements were also carried out, the results showed good agreement with the corresponding simulation results.
Concise Route to Highly Reactive Ruthenium Metathesis Catalysts Containing a Labile Donor and an N-Heterocyclic Carbene (NHC) Ligand (2003)

Complex 1a, containing two labile phosphine ligands, is a versatile precursor to the important class of olefin metathesis catalysts containing an activating NHC ligand and a labile phosphine donor. The lability of the remaining PPh3 ligand can also permit disubstitution by IMes; this side reaction is easily prevented by precise stoichiometric control.
Hyperglycaemia induced by anaesthesia in the american cockroach, <i>Periplaneta americana</i> L. (1973)

A hyperglycaemic response is elicited in adult males of the american cockroach, Periplaneta americana, within 60 min of anaesthetizing insects using nitrogen, chilling, or diethyl ether. Hyperglycaemia is also produced as a result of handling insects without anaesthesia. Insects which have been anaesthetized with carbon dioxide do not exhibit a marked change in haemolymph sugar concentration.
