A hardware accelerated multilevel visual classifier for embedded visual-assist systems (2014)

Embedded visual assist systems are emerging as increasingly viable tools for aiding visually impaired persons in their day-to-day life activities. Novel wearable devices with imaging capabilities will be uniquely positioned to assist visually impaired in activities such as grocery shopping. However, supporting such time-sensitive applications on embedded platforms requires an intelligent trade-off between accuracy and computational efficiency. In order to maximize their utility in real-world scenarios, visual classifiers often need to recognize objects within large sets of object classes that are both diverse and deep. In a grocery market, simultaneously recognizing the appearance of people, shopping carts, and pasta is an example of a common diverse object classification task. Moreover, a useful visual-aid system would need deep classification capability to distinguish among the many styles and brands of pasta to direct attention to a particular box. Exemplar Support Vector Machines (ESVMs) provide a means of achieving this specificity, but are resource intensive as computation increases rapidly with the number of classes to be recognized. To maintain scalability without sacrificing accuracy, we examine the use of a biologically-inspired classifier (HMAX) as a front-end filter that can narrow the set of ESVMs to be evaluated. We show that a hierarchical classifier combining HMAX and ESVM performs better than either of the two individually. We achieve 12% improvement in accuracy over HMAX and 4% improvement over ESVM while reducing computational overhead of evaluating all possible exemplars.
Difficult asthma (1998)

Asthma is usually easy to manage, but approximately 5% of patients are not controlled even on high doses of inhaled corticosteroids. It is important to assess these patients carefully in order to identify whether there are any correctable factors that may contribute to their poor control. It is critical to make a diagnosis of asthma and to exclude other airway diseases, particularly chronic obstructive pulmonary disease (COPD), and vocal cord dysfunction ("pseudo-asthma"). Poor adherence to therapy, particularly inhaled corticosteroids, is a common reason for a poor response. There may be unidentified exacerbating factors, including unrecognized allergens, occupational sensitizers, dietary additives, drugs, gastro-oesophageal reflux, upper airway disease, or other systemic diseases, that need to be identified and avoided or treated. Psychological factors may be important in some patients, but it is difficult to know whether these are causal or secondary to troublesome disease. Some patients have instability of their asthma, with resistant nocturnal asthma, premenstrual exacerbations or chaotic and unpredictable instability (brittle asthma). A few patients are completely resistant to corticosteroids, but more patients are relatively resistant and require relatively high doses of corticosteroids to control their symptoms (steroid-dependent). Some patients develop progressive loss of lung function, as in patients with COPD. Management of patients with difficult asthma should be supervised by a respiratory specialist and should involve careful assessment to confirm a diagnosis of asthma, identification and treatment of exacerbating factors, particularly allergens, and recording of peak expiratory flow patterns. A period of hospital admission may be the best way to assess and manage these patients. Treatment involves optimizing corticosteroids therapy, assessing additional controllers such as long-acting inhaled or subcutaneous beta2-agonists or subcutaneous, theophylline and antileukotrienes. In some patients, the use of immunosuppressive treatments may reduce steroid requirements, although these treatments are rarely effective and have side-effects. In the future, the nonsteroid anti-inflammatory treatments now in development may be useful in these patients.

Ab initio self-consistent many-body theory of polarons at all couplings (2022)

A self-consistent many-body theory of polarons is presented. This unifies weak- and strong-coupling approaches to the electron-phonon interaction from first principles, opening the door toward a full characterization of polaronic effects in materials at all coupling strengths.
Robust High-dimensional Bioinformatics Data Streams Mining by ODR-ioVFDT (2017)

Outlier detection in bioinformatics data streaming mining has received significant attention by research communities in recent years. The problems of how to distinguish noise from an exception and deciding whether to discard it or to devise an extra decision path for accommodating it are causing dilemma. In this paper, we propose a novel algorithm called ODR with incrementally Optimized Very Fast Decision Tree (ODR-ioVFDT) for taking care of outliers in the progress of continuous data learning. By using an adaptive interquartile-range based identification method, a tolerance threshold is set. It is then used to judge if a data of exceptional value should be included for training or otherwise. This is different from the traditional outlier detection/removal approaches which are two separate steps in processing through the data. The proposed algorithm is tested using datasets of five bioinformatics scenarios and comparing the performance of our model and other ones without ODR. The results show that ODR-ioVFDT has better performance in classification accuracy, kappa statistics, and time consumption. The ODR-ioVFDT applied onto bioinformatics streaming data processing for detecting and quantifying the information of life phenomena, states, characters, variables and components of the organism can help to diagnose and treat disease more effectively.
Four-wave mixing in microstructure fiber (2001)

Summary form only given. Recently much excitement has been generated over the application of microstructure fibers (MF) in nonlinear optics. We report what we believe is the first controlled FWM experiment in a MF. We demonstrate achieving nondegenerate parametric gain based on phase-matched FWM for a pump wavelength of 782 nm, which is near the /spl lambda//sub 0/ of our microstructure fiber. Since the dispersion characteristics of these fibers can be adjusted during the fabrication process, our experiment demonstrates the potential use of MF in devices such as broadband parametric amplifiers and wavelength shifters. The final goal of our project is to demonstrate quantum correlations in beams generated through FWM in such MF in order to create a source of polarization-entangled photon pairs. Such a device operating near 800 nm could merge nicely with a rubidium based trapped-atom quantum memory.
Uniaxial stress/strain of meteorites (2011)

We have begun a project of measuring the stress vs strain relationship and fracture strength of an assortment of meteorites. This information will be valuable in modeling the response of asteroidal surfaces to cratering, accretion, and disruption events, and the interpretation of meteors and bolides. It could also provide insights into the nature of meteorite lithification.

A New Wireless Sensor for Intravenous Dripping Detection (2007)

Nowadays the use of wireless technologies provides a great benefit to the society. This article shows a wireless sensor network for Intravenous Dripping System, which can detect when an intravenous liquid, provided to patients in hospitals, run out, as well as detecting obstructions in the catheter. This way, the attention in sanitary centers is more efficient and immediate, as the observation of the state of the container will not need human supervision. The work displayed in this article is still being developed within the framework of INTER projects founded by the Basque Government, in cooperation with Atica Innovation.

Chimeric Antigen Receptor T-cell Therapy in Hematologic Malignancies and Patient-reported Outcomes: A Scoping Review (2022)

The inclusion of patient-reported outcome (PRO) measures in chimeric antigen receptor (CAR) T-cell therapy research is critical for understanding the impact of this novel approach from a unique patient standpoint. We performed a scoping review to map the available literature on the use of PRO measures in CAR T-cell therapy studies of patients with hematologic malignancies published between January 2015 and July 2022. Fourteen studies were identified, of which 7 (50%) were investigational early-phase trials, 6 (42.9%) were observational studies, and 1 (7.1%) was a pilot study. The EQ-5D and the PROMIS-29 were the 2 most frequently used PRO measures, being included in 6 (42.9%) and 5 (35.7%) studies, respectively. Despite differences in study designs, there seems to be evidence of improvements over time since CAR T-cell infusion in important domains such as physical functioning and fatigue, at least in patients who respond to therapy. Overall, the studies identified in our review have shown the added value of PRO assessment in CAR T-cell therapy research by providing novel information that complements the knowledge on safety and efficacy. However, there are several questions which remain to be answered in future research. For example, limited evidence exists regarding patient experience during important phases of the disease trajectory as only 4 (28.6%) and 5 (35.7%) studies provided information on PROs during the first 2 weeks from CAR T-cell infusion and after the first year, respectively. Time is ripe for a more systematic implementation of high-quality PRO assessment in future clinical trials and in real-life settings of patients treated with CAR T-cell therapy.
The Design of Robust Phase Oscillator for Wearable Robotic Systems (2019)

Abstract This paper presents the design of a phase-based robust oscillator for wearable robots that assists the human performing periodic or repetitive tasks. The robustness of the phase oscillator controller is evaluated by finding bounds for perturbations that guaranteed the stability of the output. Then, the Lyapunov redesign method is applied to construct a robust controller using a bounding function which can handle the uncertainties such as noise and perturbations in the overall human-robot system. The robust controller produces a bounded control signal to modify the amplitude and frequency of the resulting second-order oscillator to modulate the stiffness and damping properties. In this paper, the focus is put on the wearable robot that assists human hip joint while performing periodic activities such as walking. The proposed approach is verified through a simple pendulum experiment. The results show that a better limit cycle can be obtained with Lyapunov redesigned phase oscillator which controls the radial spread of the steady state. Finally, the potential of the proposed approach for hip assistance in a healthy subject wearing HeSa (Hip Exoskeleton for Superior Assistance) during periodic activities are discussed.

Integrated microphone with CMOS circuits on a single chip (2003)

Summary form only given. The first integration of a microphone together with CMOS circuits on a single chip has been demonstrated. It was found that the processes needed to make the microphone can be articulated with a commercial CMOS fabrication line. The microphones, squares 2 mm on a side, were fabricated by combining micromachining procedures (to produce a thin silicon-nitride diaphragm) with ZnO thin-film layers which are used as piezoelectric transducers. The circuits integrated with the microphones consist mainly of several configurations of analog standard cells that were designed and proven for building-block applications. The frequency responses of the integrated microphones are plotted.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Traditional Society and Urban Democratic Policing in Botswana (2007)

Traditional African systems of social control typically have revolved around deference to chieftaincy authorities. During the colonial period, developmental neglect and a subsistence/feudal mode of production in Botswana produced a model of customary social control. Since independence, however, Botswana has forged extraordinary rates of economic and urban growth placing strains on both its adherence to traditional norms and its attempt to construct a police institution based on the rule of law. Drawing on official data and field interviews, this paper seeks to understand some of the constraints encountered in establishing Third World democratic police forces.

The Role of Substituent Effects in Tuning Metallophilic Interactions and Emission Energy of Bis‐4‐(2‐pyridyl)‐1,2,3‐triazolatoplatinum(II) Complexes (2015)

The photoluminescence spectra of a series of 5-substituted pyridyl-1,2,3-triazolato Pt(II) homoleptic complexes show weak emission tunability (ranging from λ=397-408 nm) in dilute (10(-6) M) ethanolic solutions at the monomer level and strong tunability in concentrated solutions (10(-4) M) and thin films (ranging from λ=487-625 nm) from dimeric excited states (excimers). The results of density functional calculations (PBE0) attribute this "turn-on" sensitivity and intensity in the excimer to strong Pt-Pt metallophilic interactions and a change in the excited-state character from singlet metal-to-ligand charge transfer ((1)MLCT) to singlet metal-metal-to-ligand charge transfer ((1)MMLCT) emissions in agreement with lifetime measurements.
Modification of Wood Flour Surfaces by Esterification with Acid Chlorides: Use in HDPE/Wood Flour Composites (2009)

Abstract Modification of wood fiber/flour (WF) surfaces can improve their compatibility with hydrophobic plastic matrices and reduce composite water uptake. WF was esterified with octanoyl chloride and palmitoyl chloride. Modified WF was analyzed by FT-IR. More extensive esterification occurred in highly polar dimethylformamide (DMF) than in much less polar CHCl3 or methyl tert-butyl ether (MTBE). DMF penetrates into the fiber far more than CHCl3 or MTBE, making more –OH groups available for esterification. Increasing the acid chloride chain length from C8 to C16 decreased the mole fraction of esterification. Longer chains cover surface –OH groups, retarding reactions with nearby hydroxyls after esterification. Longer chain acid chlorides also have lower reactivity and penetrate into the hydrophilic wood fiber more slowly. Modified wood flour surfaces were covered by a hydrophobic layer of ester groups (SEM). Modified wood flour surfaces and WF/HDPE composite fracture surfaces were studied by SEM. C8-modified wood flour (60 wt%)/HDPE composites exhibited far less water absorption after 24 h and 216 h immersions compared with unmodified WF (60 wt%)/HDPE composites. Water absorption continues over the 216 h period. Esterified WF/HDPE composites exhibited lower flexural strengths and moduli. In contrast to C8-esterification, the addition of maleated polypropylene (MAPP) to WF/HDPE composites improved composite mechanical performance and gave similar water absorption properties to C8-esterified WF composites.

Regulation of Intestinal Proglucagon- Derived Peptide Secretion by Intestinal Regulatory Peptides* (1991)

The physiological regulation of intestinal proglucagon-derived peptide secretion has not been well studied. We have therefore used a fetal rat intestinal cell culture model to investigate the control of secretion of the gut glucagon-like immunoreactive (GLI) peptides by other intestinal regulatory peptides in vitro. Secretion of the intestinal GLI peptides was found to be stimulated in a dose-dependent fashion by the intestinal endocrine peptide, gastric inhibitory peptide (at greater than or equal to 10(-10) M, P less than 0.05), and by the neurocrine peptides, gastrin-releasing peptide (at greater than or equal to 10(-12) M, P less than 0.05), and calcitonin gene-related peptide (at greater than or equal to 10(-8) M, P less than 0.05). Gastrin-releasing peptide and its amphibian equivalent, bombesin were equipotent in stimulating GLI peptide secretion. In contrast, the endocrine and neurocrine intestinal somatostatin-related peptides, somatostatin-28 and -14, inhibited release of the GLI peptides, at concentrations of 10(-10) (P less than 0.01) and 10(-8) (P less than 0.01) M, respectively, with significant differences in potency between the two peptides detected at 10(-10) M (P less than 0.05). The inhibitory effects of both somatostatin-28 and -14 could be blocked by preincubation of the cells with pertussis toxin (P less than 0.05). Dose-dependent stimulation of gut GLI peptide secretion was also detected in response to treatment of cultured cells with sodium oleate (at 10(-4) M; P less than 0.05), or with the cholinergic agonist bethanecol (at greater than or equal to 100 microM; P less than 0.05). Other endocrine [cholecystokinin, glucagon, glucagon-like peptide-1(1-37), glucagon-like peptide-1(7-37), glucagon-like peptide-2, neurotensin, and peptide YY] and neurocrine (vasoactive intestinal peptide) peptides, and the synthetic glucocorticoid, dexamethasone, were without effect on secretion of the gut GLI peptides, at doses of 10(-12) to 10(-6) M. The results of the present study therefore demonstrate that secretion of the intestinal proglucagon-derived peptides is under the regulatory control of a wide variety of intestinal endocrine and neurocrine peptides, as well as nutrients (fats) and neurotransmitters (acetylcholine).
Advances in the medical and surgical treatment of Takayasu arteritis (2004)

In the future, greater therapeutic success may be achieved by addressing both the inflammatory and the myointimal proliferative components of Takayasu arteritis. New drugs that target intimal hyperplasia, as well as drug-eluting stents, deserve to be studied for possible utility as adjuncts to present treatments.
Probiotics partially attenuate the severity of acute kidney injury through an immunomodulatory effect (2021)

Prior supplementation with BGN4 significantly attenuated the severity of IRI and secondary liver injury. This renoprotective effect was associated with increased Foxp3 and reduced IL-17A expression in the colon, MNL, and kidney, suggesting that BGN4-induced immunomodulation might contribute to its renoprotective effects. Probiotics may therefore be a promising strategy to reduce AKI severity and/or remote organ injury.
A Microarray-Based Method to Profile Global microRNA Expression in Human and Mouse (2007)

The microRNAs (or miRNAs) are small noncoding RNAs (21-25 nt) that are processed from large hairpin RNA precursors and are believed to be involved in a wide range of developmental and cellular processes, by either repressing translation or triggering mRNA interference (RNA interference). Over 200 of distinct genes encoding miRNAs have been identified through either computer-assisted approaches or complementary deoxyribonucleic acid cloning strategies in many organisms including worm, plants, flies, mouse, and human. Recently, a microarray based robust method to profile miRNAs expression in organs cell lines and tissues in mammalians were developed (1). Using this method, we have identified a group of miRNAs preferentially expressed in human primary adipocytes and knocking down one such miRNA (miRNA 143) reverses the differentiation process (2). Groups of kidney specific miRNAs share evolutionary conserved phylogenetic foot print Ets 1 in the upstream of the miRNA, possibly important for kidney physiological maintenance were reported. A detail protocol of the method are discussed to develop miRNA profile for global gene expression in tissues, organs, and cell lines in eukaryotes.
Control of data communications networks in space (1978)

This paper presents an overview of a data network flow control problem in which the nodes of the communication subnet are earth satellites. Among the unique aspects of such a problem is the time varying nature of the network links caused by earth occlusion. Following a discussion of the physical configuration of such networks, a discrete version of the network control problem is presented. A brief discussion is given of the Dantzig-Wolfe approach used in its solution, together with an assessment of the utility of such an approach based upon numerical results obtained using a time-stepped simulation of network operation.
