Free-form integrator array optics (2005)

A new design method of free-form Kohler integrator array optics is presented. Only few solutions to the integrator design problem are known, which apply for specific and simple source and targets (for instance, flat integrator lenslet arrays when the source and target are squares located at infinity). The method presented here find more general solutions and the resulting optics is formed by two arrays of free-form optical surfaces (which can be either reflective of refractive). The contour curves of the array units are also obtained from the design. Two types of Kholer integrators will be defined, depending if they integrate only along one direction across the source (one-directional integrators) or in the two directions (two-directional integrators). This design method has been applied for an ultra-compact high efficiency LED low beam head lamp producing a legal pattern independently of the chip luminance variation and permitting LED position tolerances of ±200 microns. The ray tracing proves that the high gradient (0.32) and its vertical position in the pattern remain invariable when chip is moved.
Apparatus for Preparing Thermoplastic Composites (1987)

The properties of high performance composites with semi-crystalline thermoplastic matrices are dependent upon the processing conditions during manufacturing. To study the relationship between processing and material properties, a low cost molding apparatus was developed and evaluated. This apparatus is capable of processing both thermoplastic composite and pure thermoplastic polymer test specimens at controlled combinations of cooling rate, molding temperature and consolidation pressure. It consists of a water cooled aluminum mold, a high flow rate water pump and a hydraulic molding press with heated platens. A description of the molding apparatus is presented along with a detailed descrip tion of the molding procedures used to fabricate and anneal both composite and pure polymer specimens. Using this apparatus specimens of carbon fiber/PEEK and PEEK polymer composites were molded at cooling rates ranging from 0.01 °F/min up to as high as 21,000°F/min. Differential Scanning Calorimetry (DSC) testing showed specimen crystallinities ranging from 0 to 45 percent crystallinity are readily obtainable.
Les cellules tueuses : voies lytiques et régulation (2004)

Les cellules de l’immunite a mediation cellulaire, lymphocytes T et cellules tueuses naturelles (NK), jouent un role cle dans la reponse de l’hote contre les agents infectieux et les cellules tumorales. Les strategies anti-tumorales se fondent, pour la plupart, sur le caractere immunogene de la tumeur et de l’activation de la reponse lymphocytaire T specifique. Cependant, cette reponse immunitaire n’est pas toujours suffisamment efficace pour prevenir l’apparition et limiter la croissance des tumeurs. Les cellules cancereuses sont alors tolerees par le systeme immunitaire. L’echappement tumoral a l’immunosurveillance concerne a la fois la cellule tumorale mais egalement le systeme immunitaire et implique differents mecanismes : la voie perforine/granzymes et la voie des recepteurs a domaines de mort. Une meilleure comprehension de ces mecanismes de tolerance est un defi majeur pour faire progresser l’immunotherapie.
Thermostable Europium Polymer Crystalline Spherical Beads and Their Photophysical Properties (2023)

Among the various luminescent material series, lanthanide coordination polymer crystals have attracted attention for their characteristic photophysical properties based on the arrangement of lanthanide ions and organic linker ligands.Here, we demonstrate the morphology controllability of the thermostable crystalline europium coordination polymer [Eu(hfa) 3 dpbp] n , [hfa: hexafluoro-acetylacetonate; dpbp: 4,4'-bis(diphenylphosphoryl) biphenyl] to realize transparent phosphors.The obtained spherical Eu 3+ -coordination particles were characterized using X-ray diffraction, scanning electron microscopy, dynamic light scattering measurements, and thermogravimetric analysis.The knowledge obtained is expected to be widely used as a transparent material development technique for new lanthanide-based coordination phosphors.
EMOTION DETECTION IN EMAIL CUSTOMER CARE (2012)

Prompt and knowledgeable responses to customers’ email are critical in maximizing customer satisfaction. Such messages often contain complaints about unfair treatment due to negligence, incompetence, rigid protocols, unfriendly systems, and unresponsive personnel. In this paper, we refer to these email messages as emotional email . They provide valuable feedback to improve contact center efficiency and the quality of the overall customer care experience, which in turn results in increased customer retention. We describe a method that uses salient features to identify emotional email in the customer care domain. Salient features in customer care related email are expressions of customer frustration, dissatisfaction with the business, and threats to either leave, take legal action, and/or report to authorities. Compared to a baseline system using word unigram features, our proposed approach significantly improves emotional email detection performance.
Sum Spectral Efficiency Maximization in Massive MIMO Systems: Benefits from Deep Learning (2019)

This paper investigates the joint data and pilot power optimization for maximum sum spectral efficiency (SE) in multi-cell Massive MIMO systems, which is a non-convex problem. We first propose a new optimization algorithm, inspired by the weighted minimum mean square error (MMSE) approach, to obtain a stationary point in polynomial time. We then use this algorithm together with deep learning to train a convolutional neural network to perform the joint data and pilot power control in sub-millisecond runtime, making it suitable for online optimization in real multi-cell Massive MIMO systems. The numerical result demonstrates that the solution obtained by the neural network is $1\%$ less than the stationary point for four-cell systems, while the sum SE loss is $2\%$ in a nine-cell system.

Define privacy-preserving setbase drawer size standard: A &#x220A;-closeness perspective (2013)

Shamir proposed the setbase approach as a means of improving security and privacy of the traditional biometric system. As a result of the limitation of the current setbase filling procedure, we demonstrate that there are potential privacy weaknesses due to non-default distributions on attributes inside the identity database. We introduce in this paper, the concept of ϵ-closeness as a general framework to describe quantitatively the distribution anomaly. As a consequence, we are able to formulate a privacy-preserving drawer size standard for the setbase that includes the non-default distribution cases.
Inhibition of protein kinase C decreases prostaglandin‐induced breakdown of the blood‐retinal barrier (2003)

Breakdown of the blood-retinal barrier (BRB) occurs in several retinal diseases and is a major cause of visual loss. Vascular endothelial growth factor (VEGF) has been implicated as a cause of BRB breakdown in diabetic retinopathy and other ischemic retinopathies, and there is evidence to suggest that other vasopermeability factors may act indirectly through VEGF. In this study, we investigated the effect of several receptor kinase inhibitors on BRB breakdown resulting from VEGF, tumor necrosis factor-alpha (TNF-alpha), interleukin-1beta (IL-1beta), insulin-like growth factor-1 (IGF-1), prostaglandin E1 (PGE(1)), or PGE(2). Inhibitors of VEGF receptor kinase, including PKC412, PTK787, and SU1498, decreased VEGF-induced breakdown of the BRB. None of the inhibitors blocked leakage caused by TNF-alpha, IL-1beta, or IGF-1 and only PKC412, an inhibitor of protein kinase C (PKC) as well as VEGF and platelet-derived growth factor (PDGF) receptor kinases, decreased leakage caused by prostaglandins. Since the other inhibitors of VEGF and/or PDGF receptor kinases that do not also inhibit PKC had no effect on prostaglandin-induced breakdown of the BRB, these data implicate PKC in retinal vascular leakage caused by prostaglandins. PKC412 may be useful for treatment of post-operative and inflammatory macular edema, in which prostaglandins play a role, as well as macular edema associated with ischemic retinopathies.
The Effect of Hemoglobin Concentration on Peritoneal Mass Transfer and Drain Volumes in Continuous Ambulatory Peritoneal Dialysis (1992)

Peritoneal transfer of small solutes and water is not influenced by hemoglobin level, and does not change following otherwise effective treatment with rHuEPO.
Prophylactic Antibiotic Reduces the Risk of Peritonitis after Invasive Gynecologic Procedures (2019)

<i>Background:</i>Peritonitis is a serious complication after invasive procedures in patients undergoing peritoneal dialysis (PD). Most studies that have investigated peritonitis following invasive gynecologic procedures enrolled small patient populations. This study focuses on the clinical presentation, outcomes, and effects of prophylactic antibiotic use before invasive techniques.<i>Methods:</i>A retrospective study was conducted on patients who underwent invasive gynecologic procedures between 2005 and 2015 in a tertiary medical center. Eligible patients were identified and enrolled and their demographic data were collected. The use of prophylactic antibiotics and the outcomes of peritonitis were recorded.<i>Results:</i>Twenty-six gynecologic procedures were performed on 18 PD patients. Seven episodes of peritonitis occurred in 6 patients after invasive gynecologic procedures. Eleven procedures were preceded by prophylactic antibiotic treatment (6 oral cefadroxil, 1 oral cefuroxime, 1 oral clindamycin, 1 intravenous [IV] ceftriaxone, 1 IV ceftazidime, and 1 IV cefazolin). The pathogens were diverse (group B <i>Streptococcus</i>, group D <i>Streptococcus</i>, <i>E. coli</i>, and <i>Enterococcus</i>). All episodes of peritonitis were successfully treated using intraperitoneal antibiotics without recurrence, technique failure, or mortality. The odds ratio of peritonitis in the non-prophylaxis group was 20.29 (95% confidence interval 1.01 - 406.35, <i>p</i> = 0.0103).<i>Conclusion:</i>The use of prophylactic antibiotic treatment considerably reduced the risk of peritonitis after invasive gyne co logic procedures.
Documenting Physical Objects with Live Video and Object Detection (2019)

Responding to requests for information from an application, a remote person, or an organization that involve documenting the presence and/or state of physical objects can lead to incomplete or inaccurate documentation. We propose a system that couples information requests with a live object recognition tool to semi-automatically catalog requested items and collect evidence of their current state.
Asymmetric oxidation of sulfides catalysed by an iron complex of C 2-chiral strapped porphyrin as a conceptually new P-450 model catalyst (1992)

Asymmetric oxidation of aryl sulfides by iodosobenzene has been achieved using the novel iron porphyrin catalysts derived from the antipodes of a C2-chiral 1,4-xylylene-strapped porphyrin, affording the corresponding sulfoxides in 18–71% enantiomeric excess.
Impact of the Family and Household Environment on Pediatric Atopic Dermatitis in Japan (2023)

Pediatric atopic dermatitis (AD) can negatively impact the family quality of life (QoL). We report data from the real-world Epidemiology of Children with Atopic Dermatitis Reporting on their Experience (EPI-CARE) study in Japanese pediatric patients, focusing on disease impact on family QoL. Children and adolescents aged 6 months to <18 years completed an online survey between September 2018-December 2019. The impact of disease severity on family QoL and its effect on parents' time were assessed using the dermatitis family impact (DFI) questionnaire. The impact of a family history of allergic conditions, current residency, second-hand smoke exposure, and household pets on AD prevalence and severity was also assessed. Family QoL decreased as AD severity increased, particularly in families with children aged <6 years; but had the greatest impact on sleep and tiredness in families with children aged <12 years. Parents spent at least 4.6 h/week caring for children <6 years, including those with mild symptoms. Most children (>80%) had a family history of allergic conditions; AD prevalence was increased in those exposed to second-hand smoke or household pets. This study demonstrated that pediatric AD in Japanese individuals has negative impacts on family QoL and that family and household environments can influence pediatric AD prevalence.
Al-2.58 Image (In Lithography) (2021)

As increasingly smaller molecular materials and material structures are devised or developed for technological applications, the demands on the processes of lithography now routinely include feature sizes that are of the order of 10 nm. In reaching such a fine level of resolution, the methods of lithography have increased markedly in sophistication and brought into play 2terminology that is unfamiliar, on the one hand, to scientists tasked with the development of new lithographic materials or, on the other, to the engineers who design and operate the complex equipment that is required in modern-day processing. Publications produced by scientists need to be understood by engineers and vice versa, and these commonly arise from collaborative research that draws heavily on the terminology of two or more of the traditional disciplines. It is developments in polymer science and material science that lead progress in areas that cross traditional boundaries, such as microlithography. This document provides the exact definitions of a selection of unfamiliar terms that researchers and practitioners from different disciplines might encounter.
A Test of the Double-Strand Break Repair Model for Meiotic Recombination in Saccharomyces cerevisiae (1996)

We tested predictions of the double-strand break repair (DSBR) model for meiotic recombination by examining the segregation patterns of small palindromic insertions, which frequently escape mismatch repair when in heteroduplex DNA. The palindromes flanked a well characterized DSB site at the ARG4 locus. The "canonical" DSBR model, in which only 5' ends are degraded and resolution of the four-stranded intermediate is by Holliday junction resolvase, predicts that hDNA will frequently occur on both participating chromatids in a single event. Tetrads reflecting this configuration of hDNA were rare. In addition, a class of tetrads not predicted by the canonical DSBR model was identified. This class represented events that produced hDNA in a "trans" configuration, on opposite strands of the same duplex on the two sides of the DSB site. Whereas most classes of convertant tetrads had typical frequencies of associated crossovers, tetrads with trans hDNA were parental for flanking markers. Modified versions of the DSBR model, including one that uses a topoisomerase to resolve the canonical DSBR intermediate, are supported by these data.
Development of a stable, high-repetition rate, 1W femtosecond regenerative amplifier system for biomedical applications (2006)

We have developed a high-repetition, 1-W, and 70 fs regenerative amplifier system. The stable operation was obtained due to a seeding fiber laser, a compact folded cavity, and a green pump source built by ourselves.
Vehicle Reliability and Maintenance CleanFleet Alternative Fuels Project (1995)

&lt;div class="htmlview paragraph"&gt;The CleanFleet project was a 24-month demonstration of five alternative motor fuels and a control gasoline in 111 FedEx delivery vans. Delivery vans from Chevrolet, Dodge, and Ford were operated on compressed natural gas (CNG), M-85 (methanol containing 15 percent RFG), propane gas, and California Phase 2 reformulated gasoline (RFG). Control vans for each fleet were operated on gasoline. Electric vans on loan from Southern California Edison were also used by FedEx. Data were gathered on vehicle emissions, fleet operations, and facility and vehicle capital and operating costs.&lt;/div&gt; &lt;div class="htmlview paragraph"&gt;This paper focusses on vehicle reliability and maintenance. Maintenance experience is described, vehicle utilization is discussed, the results of oil analysis are presented, and future engine teardown and inspection plans are described.&lt;/div&gt;
Effects of Interfacial Modifications on Electrical Properties of Laminar Composite Dielectrics (2010)

The reported work highlights that both polarizibility and quasi-DC conductivity, the two most important parameters for high energy density materials, can be influenced by the surface polarity of an oxide and interfacial surface tension between the oxide and polymer in a laminar composite. Surface modification of laminar composites, composed of thermally grown silica and vapor phase grown Parylene C thin films using organosilanes, was used to control silica surface polarity and interfacial surface tension. Surface polarity of thermally grown silica was found to control the interfacial dipolar energy states.

New method of design of nonimaging concentrators (1992)

A new method of designing nonimaging concentrators is presented and two new types of concentrators are developed. The first is an aspheric lens, and the second is a lens-mirror combination. A ray tracing of three-dimensional concentrators (with rotational symmetry) is also done, showing that the lens-mirror combination has a total transmission as high as that of the full compound parabolic concentrators, while their depth is much smaller than the classical parabolic mirror-nonimaging concentrator combinations. Another important feature of this concentrator is that the optically active surfaces are not in contact with the receiver, as occurs in other nonimaging concentrators in which the rim of the mirror coincides with the rim of the receiver.
FOURIER NEURAL NETWORKS: AN APPROACH WITH SINUSOIDAL ACTIVATION FUNCTIONS 1 (2003)

This paper presents some ideas about a new neural network architecture that can be compared to a Fourier analysis when dealing periodic signals. Such architecture is based on sinusoidal activation functions with an axo-axonic architecture (1). A biological axo-axonic connection between two neurons is defined as the weight in a connection in given by the output of another third neuron. This idea can be implemented in the so called Enhanced Neural Networks (2) in which two Multilayer Perceptrons are used; the first one will output the weights that the second MLP uses to computed the desired output. This kind of neural network has universal approximation properties (3) even with lineal activation functions.
Age and sex-dependent trends in pulmonary embolism testing and derivation of a clinical decision rule for young patients (2015)

Young patients are frequently imaged for PE and have lower positive imaging rates than older patients. After further validation, application of our proposed rule for excluding young patients from PE imaging could reduce imaging, increase the positive rate of imaging and result in a low rate of missed PE among those excluded from imaging.
In vivo degradation of magnesium alloy LA63 scaffolds for temporary stabilization of biological myocardial grafts in a swine model (2013)

Synthetic or biological patch materials used for surgical myocardial reconstruction are often fragile. Therefore, a transient support by degradable magnesium scaffolds can reduce the risk of dilation or rupture of the patch until physiological remodeling has led to a sufficient mechanical durability. However, there is evidence that magnesium implants can influence the growth and physiological behavior of the host's cells and tissue. Hence, we epicardially implanted scaffolds of the magnesium fluoride-coated magnesium alloy LA63 in a swine model to assess biocompatibility and degradation kinetics. Chemical analysis of the pigs' organs revealed no toxic accumulation of magnesium ions in the skeletal muscle, myocardium, liver, kidney, and bone of the pigs 1, 3, and 6 months postimplantation. The implants were surrounded by a fibrous granulation tissue, but no signs of necrosis were histologically evaluable. A sufficiently slow degradation rate of the magnesium alloy scaffold can be demonstrated via micro-computed tomography investigation. We conclude that stabilizing scaffolds of the magnesium fluoride-coated magnesium alloy LA63 can be used for epicardial application because no significant adverse effects to myocardial tissue were noted. Thus, degradable stabilizing scaffolds of this magnesium alloy with a slow degradation rate can extend the indication of innovative biological and synthetic patch materials.
Bundling frames to save energy while streaming video from LTE mobile device (2013)

It is becoming feasible to stream user generated video directly to the Internet, which enables a new class of exciting applications and services. However, energy consumption of smartphones that transmit the content over mobile network is a limiting factor. We study the potential of frame bundling to save energy while streaming video through a LTE uplink. Our simulation results show that if real-time streaming is not strictly necessary, bundling video frames for a few seconds before transmitting them is an effective mechanism to save energy. We analyze the energy savings achievable for different video bit rates with varying network conditions, namely round-trip time (RTT), packet loss, UE mobility, and background traffic. The results confirm that bundling remains effective also in non-ideal network conditions.
