IbPRIA 2003 (Iberian Conference on Pattern Recognition and Image Analysis) was the first of a series of similar events organized every two years, by AER-FAI (Asociación Española de Reconocimento de Formas y Análisis de Imágenes) and APRP (Associação Portuguesa de Reconhecimento de Padrões).In 2003 it was hosted by the Universitat de les Illes Balears, Departament de Ciències Matemàtiques i Informàtica.It provides an international forum for presentation of ongoing research in computer vision, image analysis, pattern recognition and speech recognition.Taking into account the new frontiers of information society programs where images and audio are fundamental in the communication process, new applications are also being addressed, namely videoconferencing, motion detection, human tracking and speech applications.The response to the call for papers for this conference was very good.From 185 full papers submitted, 130 were accepted, 72 being presented as oral presentations and 58 as posters.The review process was carried out by the Program Committee, each being paper assessed by at least two reviewers.We are specially indebted
Vector color filter array demosaicing (2001)

Single-sensor digital cameras spatially sample the incoming image using a color filter array (CFA). Consequently, each pixel only contains a single color value. In order to reconstruct the original full-color image, a demosaicing step must be performed which interpolates the missing colors at each pixel. Goals in CFA demosaicing include color fidelity, spatial resolution, no false colors, no jagged edges, and computational practicality. Most demosaicing algorithms do well for color fidelity, but there is often a trade-off between a sharp image and the so-called 'zipper effect' or jagged edge look. We propose a novel demosaicing algorithm called vector demosaicing that interpolates missing colors jointly by selecting the color vector that minimizes the sum of distances to the surrounding pixels. The selected color vector is a vector median of the surrounding pixels. The vector median forms an 'average', but preserves sharp edges. We will discuss the theory behind our approach and show experimentally how the theoretical advantages manifest themselves to improve edge resolution while retaining smoothness. Computational complexity is shown to be possible quite low, and we discuss how different approximations may affect the output.
Disulfide‐mediated dimerization of L1 Ig domains (2001)

The neural cell adhesion molecule L1 contains immunoglobulin-like (Ig) domains in its extracellular region that mediate homophilic binding, neurite outgrowth and other activities relevant to CNS development. To correlate conformations of these domains to biological function, several L1-Fc fusion proteins whose bioactivities were previously characterized were analyzed by rotary shadowing electron microscopy. We found that bioactive L1-Fcs containing Ig domains 1-4 or 1-6 exhibited extended, branched structures. In contrast, inactive L1-Fcs containing only the first two or three Ig domains assumed compact shapes that suggested interactions between the L1 arms of these proteins. Analysis of an untagged L1 fragment composed of Ig domains 1-3 demonstrated a mixture of monomeric and dimeric forms. Surprisingly, these dimers were stabilized by intermolecular disulfide bonds. Finally, cell surface L1-GFP fusion proteins containing only the first two or three Ig domains in the extracellular region also engaged in disulfide-mediated dimerization. These results suggest a novel mechanism by which mutations in L1 could interfere with its biological functioning.
Improve family planning after pregnancy. (1997)

This article discusses deficits in postpartum and postabortion care for women in developing countries. Postpartum and postabortion care frequently does not include family planning counseling. The risk of poorly timed or unwanted pregnancies is increased with a woman's inability to obtain effective contraception. Family planning programs must now address unmet need for contraception in postpartum and postabortion services, especially among rural women and adolescents. Programs need to focus on comprehensive reproductive health care. Women who deliver in medical settings may not receive contraceptive counseling after a delivery. A return to the hospital may not occur unless there are complications. Traditional birth attendants should be included in programs that provide postpartum care. Notwithstanding the lack of postpartum programs in many health settings, there are also constraints to reproductive health care in postpartum and postabortion family planning services. Sometimes family planning lacks institutional support and is poorly integrated into postpartum programs. Cultural barriers, provider biases, a lack of adequately trained personnel, legal barriers, and inadequate client-centered services interfere with delivery of family planning. Natural family planning methods are not always included in family planning services, even when culturally appropriate. The 1990 International Conference on Postpartum Contraception in Mexico and the 1993 International Workshop on Postpartum and Postabortion Family Planning in Ecuador made recommendations for improving postpartum family planning. Two key steps to improved services include training providers to counsel clients effectively and training program managers to adopt more gender-sensitive approaches to service delivery. Institutional and community support should be built on identifying needs and opportunities.
Sketch-a-TUI (2012)

Graspable tangibles are now being explored on the current generation of capacitive touch surfaces, such as the iPad and the Android tablet. Because the size and form factor is relatively new, early and low fidelity prototyping of these TUIs is crucial in getting the right design. The problem is that it is difficult for the average interaction designer to develop such physical prototypes. They require a substantial amount time and effort to physically model the tangibles, and expertise in electronics to instrument them. Thus prototyping is sometimes handed off to specialists, or is limited to only a few design iterations and alternative designs. Our solution contributes a low fidelity prototyping approach that is time and cost effective, and that requires no electronics knowledge. First, we supply non-specialists with cardboard forms to create tangibles. Second, we have them draw lines on it via conductive ink, which makes their objects recognizable by the capacitive touch screen. They can then apply routine programming to recognize these tangibles and thus iterate over various designs.
A new technique for solving robot calibration equations with partially known constraints (2002)

This paper presents an improved method for deducing kinematic parameters from constrained calibration data. The method assumes that the calibration data is constrained such that for each recorded set of joint angles, the endpoint of the robot satisfies some parameterized mathematical constraint. Suitable mathematical constraint equations include points, lines, circles, spheres, planes, hyperplanes, and others. The constraint equations do not need to be fully known; some parameters of the constraints can be unknown, and the method can still be employed. The method prescribes a nonlinear transformation of the solution equations into a new space in which a vector function of parameters multiplies a vector function of joint variables. In this transformed space, the vector function of parameters can be identified using a linear, least-squares approach. Subsequently, the transformed parameter-function vector is solved analytically for the actual parameter values. This approach differs from existing, iterative techniques in that there are no numerical problems of local-minima traps, slow convergence rates, null-space wandering or instability. Examples are presented to illustrate the method, and results are presented for calibration of an AdeptOne robot.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Self-Monitoring Effects on Articulation Carryover in School-Age Children (1992)

The purpose of this study was to field-test a treatment strategy for bringing about articulation carryover in school-age children. Subjects were 8 elementary school students who misarticulated /s/ or /r/ in conversation outside the treatment setting, but who correctly articulated the target phoneme 80% or more of the time in conversation with the speech-language pathologist in the treatment setting. The self-monitoring treatment strategy of Koegel, Koegel, and Ingham (1986) and Koegel, Koegel, Van Voy, and Ingham (1988) was selected for field-testing. Data were collected in the context of a multiple-baseline-across-subjects research design. Results of this study did not replicate the positive treatment effects found in the Koegel et al. studies. The results are discussed in relation to the subject, treatment, environment, and measurement variables that may have accounted for the discrepancy in treatment effectiveness.
Histamine Release from Rat Mast Cells by Antibodies against Rat Basophilic Leukemia Cell Membrane (1977)

Abstract Attempts were made to prepare antibodies against receptors for IgE. Rat basophilic leukemia (RBL) cells were saturated with IgE and solubilized in Nonidet P-40, and IgE receptor complexes were precipitated with anti-IgE. A rabbit was immunized with the precipitates and antibodies against cell membrane components were specifically purified by using RBL cells. After absorption, the antibody preparation (anti-RBL) was specific for mast cells but did not contain anti-IgE. Anti-RBL inhibited the binding of 125I-IgE with RBL, normal rat mast cells, and solubilized receptors. Immunofluorescence staining of RBL and mast cells with anti-RBL was significantly inhibited, if their receptors had been saturated with IgE. These results indicated that anti-RBL contained antibodies against receptor molecules. Both anti-RBL and anti-IgE induced immediate skin reactions in normal rats, whereas anti-lymphocyte serum, which cross-reacts with mast cells but lacks anti-receptors, failed to induce the reaction. Infection of rats with Nippostrongylus brasiliensis, which enhanced IgE synthesis and resulted in saturation of receptors on mast cells with IgE, increased the sensitivity of their skin to anti-IgE and abolished the reactivity to anti-RBL. The results suggested strongly that anti-receptor antibodies were responsible for the skin reactions by anti-RBL. Incubation of peritoneal mast cells from inbred Hooded Lister rats with anti-RBL resulted in histamine release without changing the viability of the cells. It appears that anti-RBL induced non-cytotoxic histamine release without participation of cell-bound IgE.
Application of 16S rDNA‐DGGE to examine the microbial ecology associated with a social wasp <i>Vespula germanica</i> (2003)

Invertebrates host numerous bacteria, with interactions ranging from pathogenesis to symbiosis. While certain symbiotic relationships have been well studied, little is known about the dynamics of these bacterial communities. Denaturing gradient gel electrophoresis (DGGE) was used to examine the bacterial microflora associated with the eusocial wasp Vespula germanica. DGGE profiles of larval guts revealed a variable microflora, suggesting that V. germanica is not dependent on a particular suite of mutualists. The variation in profiles was not related to season, nest size or macrohabitat. Sequences corresponding to Lactococcus, Lactobacillus, a novel Leuconostoc and two Rickettsiella grylli strains were obtained. DGGE proved to be a useful technique for characterizing the wasp microflora. Given the importance of microbial communities to invertebrates, there is much to be gained from the application of such techniques.
Practical resource scheduling in massive-cell deployment for 5G mobile communications systems (2015)

This paper proposes the first practical resource scheduling that increases system throughput in massive-cell deployment for 5G mobile communications systems. In 5G systems, the best combination of a huge number of antennas and user equipment for communications should be decided in the scheduling. The proposed scheme searches for the suitable combination without exhaustive search and accelerates calculation of system throughput for each combination. The scheme quickly obtains the combination for which the scheduling achieves higher system throughput, and thus the scheduling can be done within the required period. Simulation and experimental measurements show that the system throughput obtained is about seven times higher than for the conventional scheme. The proposed scheme enables a future practical 5G system.
Physiologic Control Algorithms for Rotary Blood Pumps Using Pressure Sensor Input (2002)

Hierarchical algorithms have been developed for enhanced physiologic control and monitoring of blood pumps using pressure inputs. Pressures were measured at pump inlet and outlet using APEX pressure sensors (APSs). The APS is a patented, long-term implantable, flow-through blood pressure sensor and designed to control implantable heart pumps. The algorithms have been tested using a Donavan circulatory mock-loop setup, a generic rotary pump, and LabVIEW software. The hierarchical algorithms control pump speed using pump inlet pressure as a primary independent variable and pump outlet pressure as a secondary dependent variable. Hierarchical control algorithms based on feedback from pressure sensors can control the speed of the pump to stably maintain ventricular filling pressures and arterial pressures. Monitoring algorithms based on pressure inputs are able to approximate flow rate and hydraulic power for the pump and the left ventricle.

Catalytic Asymmetric Alkylations of Ketoimines. Enantioselective Synthesis of <i>N</i>-Substituted Quaternary Carbon Stereogenic Centers by Zr-Catalyzed Additions of Dialkylzinc Reagents to Aryl-, Alkyl-, and Trifluoroalkyl-Substituted Ketoimines (2008)

Catalytic enantioselective alkylations of three classes of ketoimines are reported. Reactions are promoted in the presence 0.5-10 mol % of a Zr salt and a chiral ligand that contains two inexpensive amino acids (valine and phenylalanine) and involve Me2Zn or Et2Zn as alkylating agents. Requisite aryl- and alkyl-substituted alpha-ketoimine esters, accessed readily and in >80% yield on gram scale through a two-step sequence from the corresponding ketones, undergo alkylation to afford quaternary alpha-amino esters in 79-97% ee. Aryl-substituted trifluoroketoimines are converted to the corresponding amines by reactions with Me2Zn, catalyzed by a chiral complex that bears a modified N-terminus. The utility of the catalytic asymmetric protocols is illustrated through conversion of the enantiomerically enriched alkylation products to a range of cyclic and acyclic compounds bearing an N-substituted quaternary carbon stereogenic center.
Gray Hausdorff Distance Measure for Comparing Face Images (2006)

Human face recognition is considered to be one of the toughest problems in the domain of pattern recognition. The variations in face images due to differing expression, pose and illumination are some of the key issues to be addressed in developing a face recognition system. In this paper, a new measure called gray Hausdorff distance (denoted by H <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">pg</sub> ) is proposed to compare the gray images of faces directly. An efficient algorithm for computation of the new measure is presented. The computation time is linear in the size of the image. The performance of this measure is evaluated on benchmark face databases. The face recognition system based on the new measure is found to be robust to pose and expression variations, as well as to slight variation in illumination. Comparison studies show that the proposed measure performs better than the existing ones in most cases
Luminescence of the InGaN/GaN blue light-emitting diodes (2000)

InGaN/GaN double heterostructure (DH) and multiple quantum wells(MQW) light-emitting diodes were grown by metalorganic vapor phase epitaxy(MOVPE). Band gap narrowing of the PL spectra for the InGaN/GaN MQW LEDs can be observed at room temperature. In addition, the emission wavelength of EL and PL spectra for the MQW blue LEDs exhibit a blue-shift phenomenon when increasing the injection current and laser power, respectively. This luminescence behavior can tentatively be understood as a competition between a spectral red-shift mechanism of piezoelectricity-induced quantum-confined Stark effect(PQCSE) and a blue-shift mechanism of band-filling and charge screening effects.

A Facile and Practical Copper Powder-Catalyzed, Organic Solvent- and Ligand-Free Ullmann Amination of Aryl Halides (2011)

A facile and practical method that the copper powder-catalyzed Ullmann amination of aryl halides with aqueous methylamine under organic solvent- and ligand-free condition at 100 °C and in air gave N-arylamines as sole products in good to excellent yields. The presence of a small amount of air is essential. Other aliphatic primary amines show good to very high reactivity. Secondary amines and aniline are not reactive. Sensitive substituents (i.e., CHO, MeCO, CN and Cl) are tolerable in the reaction.
Manufacture of a Polyaniline Nanofiber Ammonia Sensor Integrated with a Readout Circuit Using the CMOS-MEMS Technique (2009)

This study presents the fabrication of a polyaniline nanofiber ammonia sensor integrated with a readout circuit on a chip using the commercial 0.35 μm complementary metal oxide semiconductor (CMOS) process and a post-process. The micro ammonia sensor consists of a sensing resistor and an ammonia sensing film. Polyaniline prepared by a chemical polymerization method was adopted as the ammonia sensing film. The fabrication of the ammonia sensor needs a post-process to etch the sacrificial layers and to expose the sensing resistor, and then the ammonia sensing film is coated on the sensing resistor. The ammonia sensor, which is of resistive type, changes its resistance when the sensing film adsorbs or desorbs ammonia gas. A readout circuit is employed to convert the resistance of the ammonia sensor into the voltage output. Experimental results show that the sensitivity of the ammonia sensor is about 0.88 mV/ppm at room temperature.
Silicone-based adhesives for long-term skin application: cleaning protocols and their effect on peel strength (2017)

Adhesives that involve adhesion to the skin have been of great technological importance in medical or pharmaceutical fields, including recently emerging wearable sensors and electronics. The objective of this work was to evaluate the performances of silicone-based adhesives with skin, using a peel adhesion test. Specifically, we explored the effect of adhesive cleansing, which is an inevitable daily event for patients' comfort in long-term applications. Firstly, three medical grade silicone gels, Silbione® RT 4717, Silbione® RT 4642, and Silpuran® 2130, were used to fabricate adhesive pads. Their peel strength values were subsequently measured and compared, among which Silbione® RT gel 4717 possessed the highest peel strength. Therefore, it was selected as the raw material to fabricate the pads with a thickness range of 640–740 μm. Secondly, the peel adhesion of Silbione® RT 4717 adhesive pad was further compared with a series of commercial products that employ various medical-grade adhesives. The peel strength results indicated that our custom-made adhesive pad had an adequately strong adhesion for clinical use. Thirdly, in order to observe and predict the long-term performance of the adhesives, an aging test was performed in an ambient environment, revealing that Silbione® RT 4717 adhesive remained highly sticky for 5 days. Lastly, adequate cleansing protocols were established by monitoring the changes in peel strength after washing and wiping events. The reusability analysis showed that Silbione® 4717 adhesive pad was reusable in a one-week period for the washing method and 3 days for the wiping method.
Joint Pose and Expression Modeling for Facial Expression Recognition (2018)

Facial expression recognition (FER) is a challenging task due to different expressions under arbitrary poses. Most conventional approaches either perform face frontalization on a non-frontal facial image or learn separate classifiers for each pose. Different from existing methods, in this paper, we propose an end-to-end deep learning model by exploiting different poses and expressions jointly for simultaneous facial image synthesis and pose-invariant facial expression recognition. The proposed model is based on generative adversarial network (GAN) and enjoys several merits. First, the encoder-decoder structure of the generator can learn a generative and discriminative identity representation for face images. Second, the identity representation is explicitly disentangled from both expression and pose variations through the expression and pose codes. Third, our model can automatically generate face images with different expressions under arbitrary poses to enlarge and enrich the training set for FER. Quantitative and qualitative evaluations on both controlled and in-the-wild datasets demonstrate that the proposed algorithm performs favorably against state-of-the-art methods.
Performance enhancement of distributed parameter systems by a class of nonlinear controls (1987)

In this paper a class of nonlinear control structures is proposed to address the phenomenon of energy exchange between certain controlled modes and uncontrolled modes in the control of distributed parameter systems. The control structure is derived by requiring the energy in the controlled modes to be dissipated in a finite time.
