Product Temperature Prediction in Hydrostatic Retorts (1983)

ABSTRACT A computer model, based on Fourier's law of heat conduction with a time-dependent boundary condition, was developed to predict the time-temperature profile at the center of a canned food processed in a hydrostatic retort. The effects, on product cooling, of various temperature/pressure events characteristic of the exit hydrostatic leg were studied by performing hydrostatic simulations. Water temperatures of 130 F, 160 F, and 190 F (54.4, 71.1 and 87.8 C) were compared in combination with (a) the 15 psig (0.72 kPa) to 0 psig (0 kPa) gradient imposed by a 39 foot (11.9 m) high exit water leg and (b) a static pressure of 15 psig (0.72 kPa). The model closely predicted product temperatures during the initial portion of the hydrostatic leg (gradient pressure) residence but temperature predictions associated with subsequent cooling were less precise. When an artificially constant overriding pressure was maintained, predicted temperatures were consistently in good agreement with those measured experimentally. This evidence suggests that external pressure-related changes in headspace volume induce convection effects that are not accounted for by the conduction model.

Sirenomelia: Review of a Rare Syndrome with Case Report, Review of Anatomy, and Thoughts on Management (2022)

Selected patients with sirenomelia may be able to walk after separation of the legs, depending on the status of other congenital differences as well as the status of the legs when separated. Careful workup with multidisciplinary planning of overall care as well as surgical care is essential.
Underwater Laser Scanner: Ray-Based Model and Calibration (2019)

Underwater 3-D perception is crucial for autonomous manipulation and mapping. Using a mirror-galvanometer system to steer a laser line projector and using triangulation with a camera it is possible to produce full 3-D perception, while avoiding moving the sensor with respect to the scene. This paper presents a ray-based model of a laser scanner and a calibration method for such a model. The model takes into account the distortion introduced to the system by the flat viewports used for both the laser and the camera. The paper also introduces the computation of elliptical cones as a way to synthesize the ray-based model and speed up the triangulation computation. The present study reports results obtained using the real sensor in a water tank to reconstruct objects and planes to assess the sensor's accuracy, as well as a comparison between the two triangulation methods (ray-based and elliptical cone).

The effect of 2-mercaptoacetyl-L-phenylalanyl-L-leucine, a specific inhibitor of Pseudomonas aeruginosa elastase, on experimental Pseudomonas keratitis in rabbit eyes (1984)

The compound 2-mercaptoacetyl-L-phenylalanyl-L-leucine (HS-Ac-Phe-Leu) is a potent and specific inhibitor of Pseudomonas aeruginosa elastase, effectively inhibiting the elastase activity both, in vitro and within the rabbit cornea. This inhibitor was therefore evaluated as an adjunct to antibiotics (gentamicin) treatment in experimentally induced Pseudomonas keratitis in rabbits. Twenty eight hours after infection, the eyes that received both, gentamicin and HS-Ac-Phe-Leu showed significantly less corneal melting than those treated with the antibiotics alone, demonstrating the beneficial effect of the inhibitor. Forty eight hours after infection, the difference in clinical appearance between the two treatment groups diminished and was statistically insignificant. No adverse effects were noted in the eyes that received the inhibitor in spite of its frequent application. The protective effect of HS-Ac-Phe-Leu, seen on the first day of the experiment suggests further exploration of the therapeutic potential of this or other, similarly structured, specific and potent inhibitors of Pseudomonas elastase.
How Art Becomes History: Essays on Art, Society, and Culture in Post-New Deal America (1993)

This study is an account of how the new art history revises the understanding of American art, society and culture of the past 50 years. It explores the overlapping social, political, cultural and aesthetic issues of post-New Deal America. The book focuses on pioneering developments in art history and cultural studies, from the dissolution of formalism in the late 1960s through the re-emergence of Marxism in the 1970s and the infusion of semiotic, feminist, psychoanalytical and racial issues in the 1980s.
Development of a portable phototherapy garment (PPG) for jaundice treatment (2016)

Phototherapy is the most common treatment used for jaundiced newborn by utilizing light sources such as fluorescent tubes, halogen lamp, fiberoptic system and LEDs to reduce bilirubin level in infants. Currently, the commonly used phototherapy devices in hospitals require continuous uninterrupted treatment for a period of time and generate considerable amount of heat that may lead to thermal injury to infants. Limited numbers of phototherapy devices in some developing and third-world countries have caused longer waiting periods between patients. Thus, a portable phototherapy device, which allows easy access and comfort to both infants and breastfeeding mothers, is very much preferred to overcome the current situation. The Portable Phototherapy Garment (PPG) uses blue surface mount device (SMD) LEDs which are arranged on a garment to deliver sufficient light exposure to infants in a safely manner. The PPG is also equipped with a body temperature and alert system to indicate any abnormal temperature and completion of treatment. The PPG was proven to reduce bilirubin level in artificial bilirubin standard solution (ABSS) more efficiently compared to fluorescent tubes.
Bortezomib Inhibits Expression of Immunosuppressive Cytokines IL‐10 and TGFβ in Cutaneous T Cell Lymphoma (2012)

CTCL is characterized by the clonal expansion of helper T cells that release the immunosuppressive cytokines IL‐10 and TGFβ, thus suppressing the immune responses. NFκB is constitutively activated in CTCL and many other cancers, where it plays a crucial role in cell survival and resistance to apoptosis. While NFκB regulation of pro‐inflammatory and anti‐apoptotic genes has been studied extensively, the NFκB regulation of immunosuppressive genes is incompletely understood. Bortezomib is the 26S proteasome inhibitor, which has shown promising results in several forms of cancer, including CTCL. We have demonstrated that bortezomib inhibits NFκB activity and expression of anti‐apoptotic genes by inducing nuclear translocation of IκBα in CTCL Hut‐78 cells. In this study, we investigated whether bortezomib inhibits expression of IL‐10 and TGFβ in Hut‐78 cells, and we analyzed the underlying mechanisms. Our results show that bortezomib inhibits both IL‐10 and TGFβ expression in Hut‐78 cells. Chromatin immunoprecipitation analyses indicated that bortezomib inhibits NFκB recruitment to the promoter regions of IL‐10 and TGFβ genes. Since a variety of malignancies utilize the immunosuppressive cytokines IL‐10 and TGFβ to evade the immune surveillance and facilitate tumor growth, a better understanding of the mechanisms regulating transcription of these cytokines may lead to more effective cancer therapies.

Synthesis, Characterization, and Field‐Effect Transistor Performance of Pentacene Derivatives (2007)

A series of functionalized pentacene derivatives based on symmetric and asymmetric substitutions of the terminal rings are synthesized (see figure). Field-effect mobilities as high as 0.23 cm2 V–1 s–1 are obtained with 2,3-dibrompentacene. These devices show improved stability compared to pentacene and exhibit no significant decrease in mobility or on/off ratio when stored in air, with and without light exposure, even after three months.

Inflammatory and Angiogenic Factors Linked to Longitudinal Microvascular Changes in Hemodialysis Patients Irrespective of Treatment Dose Intensity (2017)

Hemodialysis intensity did not predict changes in either macro- or microvascular parameters. Inflammation mediated through the IL-8 pathway predicted microvascular injury while Flt-1, a potential marker of angiogenesis and endothelial repair, might have a significant protective role. Further understanding of these pathways will be necessary to improve dialysis outcomes.
Vascular Smooth Muscle Proliferation in Hypertensive Transgenic Rats (1992)

In vascular smooth muscle cell (VSMC) cultures from Sprague-Dawley (SD) and hypertensive transgenic rats for the mouse renin gene Ren-2 (TGR), the DNA synthesis, which was analyzed by the uptake of [3H]thymidine, was higher in TGR than SD VSMCs (2.5- to 8-fold, mean of 5.6-fold) under basal conditions. DNA synthesis was increased by fetal calf serum (10%) in SD cells more than in TGR VSMCs, and was decreased by heparin (400 micrograms/ml) and by phorbol-12,13-dibutyrate (10(-7) M) in TGR VSMCs to a higher degree than in SD cells. Neither endothelin (10(-7) M), angiotensinogen (10(-8) M), the renin inhibitor CGP 29,287 (10(-4) M), angiotensin I (10(-7) M), captopril (10(-5) M), angiotensin II (10(-7) M), nor saralasin (10(-6) M) modified DNA synthesis in either type of VSMCs. Sodium nitroprusside (10(-4) and 10(-3) M) increased DNA synthesis in both kinds of VSMCs but in TGR cultures it became toxic at 10(-3) M. 8-Bromocyclic GMP (10(-7) to 10(-5) M) reduced DNA synthesis in SD cells more than in TGR VSMCs. These results suggest that (a) cellular mechanisms of proliferation appear to be more activated in TGR VSMCs, likely involving a protein kinase C-dependent pathway but not the renin-angiotensin system, and (b) in both type of cells, sodium nitroprusside possesses proliferative properties whereas 8-bromocyclic GMP has antiproliferative properties.
Thermal modeling of a pressurized air cavity receiver for solar dish Stirling system (2017)

A solar cavity receiver model for the dish collector system is designed in response to growing demand of renewable energy. In the present research field, no investigations into the geometric parameters of a cavity receiver have been performed. The cylindrical receiver in this study is composed of an enclosed bottom at the back, an aperture at the front, a helical pipe inside the cavity and an insulation layer on the external surface of the cavity. The influence of several critical receiver parameters on the thermal efficiency is analyzed in this paper: cavity inner diameter and cavity length. The thermal model in this paper is solved considering the cavity dimensions as variables. Implementing the model into EES, each parameter influence is separately investigated, and a preliminary optimization method is proposed.
Chronopotentiometric Approach of CO2Reduction in Molten Carbonates (2017)

Carbon capture and valorization is a new route increasingly discussed to reduce greenhouse gas emissions. One of the paths foreseen for CO2 valorization is its transformation into fuels by electrochemical reduction of carbon dioxide. In this approach, molten carbonates are of particular interest since they can be used to capture CO2 molecule because of its high solubility; hence, valorization by electrolysis is possible in molten carbonate media. To better understand CO2 reduction, chronopotentiometric and chronoamperometric techniques were used at gold and graphite electrodes immersed in four alkali carbonate eutectics, Li-Na, Li-K, Li-Na-K and Na-K. The results complemented a previous work based on cyclic voltammetry and confirmed the existence of a main CO2 reduction phenomena around −1.2 V vs Ag/Ag+ that involves two one-electron steps or a two-electron unique step. Transition time analysis showed that the reduction mechanism is either simultaneous reduction of CO2 adsorbed and diffusion species or rapid equilibrium between adsorbed and diffusing species. Furthermore, we identified another electrochemical system involving adsorbed CO2 and CO at higher potentials. In summary, we have succeeded in proving and précising some previous results, as well as identifying reduction mechanisms. © The Author(s) 2017. Published by ECS. All rights reserved.
Early specification of user-interfaces (1997)

The paper presents our work in the domain of formal specification of user-interfaces. We think that engineering user-interfaces would greatly benefit from the use of formal techniques. To achieve this goal, we need a framework with two properties. First, it must be based on a formal model which expresses interesting features. Second, it must lead to the implementation of tools to help validate the specification. Our approach has been to define and to formalize, with VDM, a model focusing on dialogue structures based on the notion of planning. This model provides us with the semantic foundation of a specification language which can be used as the first formal description of a user-interface. This semantics, in turn, has allowed us to implement a prototyping tool which produces an executable instance of the interface along with an interactive visualization of the dialogue structures. Such prototypes can be used during the validation process of the specification.
A Study of Human Skill Transfer for Teaching a Deburring Robot. (1996)

This paper discusses a new method for teaching a deburring robot based on demonstration of human skillful motion. The robot is programmed to adjust the tool feedrate in accordance with the varying burr characteristics, such as burr size and material properties. This dynamic change of tool feedrate is motivated by the effective human skill in performing a deburring task. The relationship between the tool feedrate and burr characteristics is obtained from human demonstration data and stored in a computer as an associative memory. This associative memory enables the robot to select the tool feedrate that well matches the burr characteristics. Therefore, the robot motion is always effective in removing burrs and generating smooth finish of workpiece surface without severe tool wear. In order to identify burr characteristics, a laser displacement sensor has been used for direct burr height measurement, and a deburring process model has been applied for material property differentiation. The learned associative memory is stored and represented by a neural network, which can be easily incorporated into robot programming. Experimental results show that a robot can perform a deburring task in a manner similar to its human teacher.

The association of uric acid with mortality modifies at old age: data from the uric acid right for heart health (URRAH) study (2021)

These results confirmed the predictive role of SUA for all-cause and CV mortality in older adults, while revealing considerable age-related differences. Mortality risk increased at higher SUA levels in participants aged 65-74, with a prognostic threshold of 4.8 mg/dl. The relationship between SUA and mortality was J-shaped in oldest participants. Large interventional studies are needed to clarify the benefits and possible risks of urate-lowering treatments in older adults.
Single chip lidar with discrete beam steering by digital micromirror device (2017)

A novel method of beam steering enables a large field of view and reliable single chip light detection and ranging (lidar) by utilizing a mass-produced digital micromirror device (DMD). Using a short pulsed laser, the micromirrors' rotation is frozen in mid-transition, which forms a programmable blazed grating. The blazed grating efficiently redistributes the light to a single diffraction order, among several. We demonstrated time of flight measurements for five discrete angles using this beam steering method with a nano second 905nm laser and Si avalanche diode. A distance accuracy of < 1 cm over a 1 m distance range, a 48° full field of view, and a measurement rate of 3.34k points/s is demonstrated.
Incorporation of Dyes into Polystyrene‐block‐poly(4‐vinylpyridine) Nanotemplates (2008)

Abstract Summary: The present study provides some basic concepts of functionalization of diblock copolymer (BC) nanotemplates for optical applications. It is focused on the polystyrene‐ block ‐poly(4‐vinylpyridine) (PS‐ b ‐P4VP) building medium which is suitable for hydrogen bonding, undergoes phase segregation, and is well‐accessible. Two techniques are described and demonstrated on several dye complexes with PS‐ b ‐P4VP. Relation between optical properties and thin film structure is tentatively studied in dependence on solvent effects in thin films.
Inosiplex in the Treatment of Subacute Sclerosing Panencephalitis (1979)

Six patients with subacute sclerosing panencephalitis were treated with the antiviral agent inosiplex. The clinical condition of four children continued to deteriorate in spite of the treatment, the condition of one remained unchanged, and that of another improved minimally. The effect of inosiplex in these patients is not evident since this group demonstrated a pattern of progression similar to that seen in subacute sclerosing panencephalitis without specific treatment.
Over-the-Air Design of GAN Training for mmWave MIMO Channel Estimation (2022)

Future wireless systems are trending towards higher carrier frequencies that offer larger communication bandwidth but necessitate the use of large antenna arrays. Signal processing techniques for channel estimation currently deployed in wireless devices do not scale well to this “high-dimensional” regime in terms of performance and pilot overhead. Meanwhile, training deep learning-based approaches for channel estimation requires large labeled datasets mapping pilot measurements to clean channel realizations, which can only be generated offline using simulated channels. In this paper, we develop a novel unsupervised over-the-air (OTA) algorithm that utilizes noisy received pilot measurements to train a deep generative model to output beamspace MIMO channel realizations. Our approach leverages Generative Adversarial Networks (GAN), while using a conditional input to distinguish between Line-of-Sight (LOS) and Non-Line-of-Sight (NLOS) channel realizations. We also present a federated implementation of the OTA algorithm that distributes the GAN training over multiple users and greatly reduces the user side computation. We then formulate channel estimation from a limited number of pilot measurements as an inverse problem and reconstruct the channel by optimizing the input vector of the trained generative model. Our proposed approach significantly outperforms Orthogonal Matching Pursuit on both LOS and NLOS channel models, and EM-GM-AMP – an Approximate Message Passing algorithm – on LOS channel models, while achieving comparable performance on NLOS channel models in terms of the normalized channel reconstruction error. More importantly, our proposed framework has the potential to be trained online using real noisy pilot measurements, is not restricted to a specific channel model and can even be utilized for a federated OTA design of a dataset generator from noisy data.
The Effect of Decision Strategy on Deciding to Defer Choice (1996)

Recent research has examined consumer decision making when the option of not choosing any of the alternatives is also provided. The findings from this research suggest that the decision to defer choice is sensitive to the uncertainty of choosing the most preferred option from the set of alternatives provided. Building on this research, the author tests whether the decision to defer choice is also influenced by task variables that influence decision uncertainty. In the first experiment, this proposition is tested for choice problems in which information on three relatively equally attractive alternatives is presented either sequentially or simultaneously. As predicted, the preference for the defer-choice option was greater when the three alternatives were presented simultaneously. A second study forced subjects into using one of four decision strategies in order to choose between two non-dominated alternatives. The preference for the no-choice option was found to be higher when the rule required explicit attribute tradeoffs and lower when it simplified choice. These results suggest that choice uncertainty is influenced by the decision strategy used to determine the preference among alternatives. We conclude with a discussion of the implications of the results for marketers' communication strategies.
Cleaner one-pot transformation of glycerol to acrylic acid and 1,2-propanediol over bifunctional Cu2O/montmorillonite catalysts without external oxygen and hydrogen (2022)

A novel process of simultaneous oxydehydration and hydrogenolysis of glycerol to acrylic acid and 1,2-propanediol over a bifunctional Cu 2 O/montmorillonite catalyst was demonstrated and the possible mechanism was proposed.
