Application of time-reversal guided waves to field bridge testing for baseline-free damage diagnosis (2006)

There is ongoing research at Carnegie Mellon University to develop a "baseline-free" nondestructive evaluation technique. The uniqueness of this baseline-free diagnosis lies in that certain types of damage can be identified without direct comparison of test signals with previously stored baseline signals. By relaxing dependency on the past baseline data, false positive indications of damage, which might take place due to varying operational and environmental conditions of in-service structures, can be minimized. This baseline-free diagnosis technique is developed based on the concept of a time reversal process (TRP). According to the TRP, an input signal at an original excitation location can be reconstructed if a response signal obtained from another point is emitted back to the original point after being reversed in a time domain. Damage diagnosis lies in the premise that the time reversibility breaks down when a certain type of defect such as nonlinear damage exists along the wave propagation path. Then, the defect can be sensed by examining a reconstructed signal after the TRP. In this paper, the feasibility of the proposed NDT technique is investigated using actual test data obtained from the Buffalo Creek Bridge in Pennsylvania.
Pheromone trail decay rates on different substrates in the Pharaoh's ant, <i>Monomorium pharaonis</i> (2003)

Abstract. Many ants use pheromone trails to organize collective foraging. This study investigated the rate at which a well‐established Pharaoh's ant, Monomorium pharaonis (L.), trail breaks down on two substrates (polycarbonate plastic, newspaper). Workers were allowed to feed on sucrose solution from a feeder 30 cm from the nest. Between the nest and the feeder, the trail had a Y‐shaped bifurcation. Initially, while recruiting to and exploiting the feeder, workers could only deposit pheromone on the branch leading to the feeder. Once the trail was established (by approximately 60 ants per min for 20 min), the ants were not allowed to reinforce the trail and were given a choice between the marked and unmarked branches. The numbers of ants choosing each branch were counted for 30 min. Initially, most went to the side on which pheromone had been deposited (80% and 70% on the plastic and paper substrates, respectively). However, this decayed to 50% within 25 min for plastic and 8 min for paper. From these data, the half‐life times of the pheromone are estimated as approximately 9 min and 3 min on plastic and paper, respectively. The results show that, for M. pharaonis , trail decay is rapid and is affected strongly by trail substrate.
Multiple Parallel Vision-Based Recognition in a Real-Time Framework for Human-Robot-Interaction Scenarios (2010)

Every day human communication relies on a large number of different communication mechanisms like spoken language, facial expressions, body pose and gestures, allowing humans to pass large amounts of information in short time. In contrast, traditional human-machine communication is often unintuitive and requires specifically trained personal. In this paper, we present a real-time capable framework that recognizes traditional visual human communication signals in order to establish a more intuitive human-machine interaction. Humans rely on the interaction partner’s face for identification, which helps them to adapt to the interaction partner and utilize context information. Head gestures (head nodding and head shaking) are a convenient way to show agreement or disagreement. Facial expressions give evidence about the interaction partners’ emotional state and hand gestures are a fast way of passing simple commands. The recognition of all interaction queues is performed in parallel, enabled by a shared memory implementation.
Site‐specific analysis of the <i>N</i>‐glycans on murine polymeric immunoglobulin A using liquid chromatography/electrospray mass spectrometry (1995)

Abstract The site‐specific distribution of oligosaccharides on murine polymeric immunoglobulin A (pIgA) consisting of two or more immunoglobulin A (IgA) antibodies connected through J‐chain was analysed by liquid chromatography/electrospray mass spectrometry. Glycopeptides from pIgA were localized in a reversed‐phase tryptic peptide chromatogram by collision excitation scanning and their amino acid sequences determined by electrospray tandem mass spectrometry and Edman degradation. Two glycosylation sites on IgA and a single glycosylation site on J‐chain were identified. Using biosynthetic constraints on carbohydrate structures, molecular mass information on the glycan moieties of the glycopeptides was translated into specific carbohydrate structure proposals. The glycopeptide incorporating the single glycosylation site at Asn49 in J‐chain carried fucosylated and non‐fucosylated di‐and triantennary N ‐acetyllactosamine type carbohydrate chains terminated by N ‐acetyl‐ and/or N ‐glycolylneuraminic acid residues. The glycosylation site in the IgA heavy chain at Asn446 contained two oligomannose‐type carbohydrate chains, one carrying five and the other six mannose residues. To the other glycosylation site in the IgA heavy chain at Asn155 one oligomannose structure, hybrid structures with the lactosamine branch terminated by either an additional galactose residue, N ‐glycolylneuraminic acid or N ‐acetylneuraminic acid, and non‐fucosylated N ‐acetyllactosamine‐type structures carrying the same terminating residues were attached. This glycosylation site was present in two separate glycopeptides differing only in their degree of carboxymethylation and yielding identical oligosaccharide distributions, thus providing additional confidence in the assignment method.
Wavelet Analysis of Skin Perfusion in Healthy Volunteers (2007)

When wavelet transformation is used in analyzing LDF time series, the different rhythms of cutaneous blood flow are made visible and quantifiable and can be assigned to different physiological origins. The application of this novel analysis method allows identifying mechanisms regulating skin perfusion, which will greatly facilitate the diagnosis of a variety of important vascular diseases, such as chronic venous insufficiency, diabetes, or neurotrophic disorders.

Probing defect dynamics in monolayer MoS2 via noise nanospectroscopy (2017)

Monolayer molybdenum disulfide (MoS<sub>2</sub>) has received intense interest as a strong candidate for next-generation electronics. However, the observed electrical properties of monolayer MoS<sub>2</sub> exhibit several anomalies: samples universally exhibit unexpectedly low mobilities, n-type characteristics, and large contact resistances regardless of contact metal work function. These anomalies have been attributed to the presence of defects, but the mechanism behind this link has been elusive. Here we report the ionization dynamics of sulfur monovacancy defects in monolayer MoS<sub>2</sub> probed via noise nanospectroscopy, realized by combining noise-current analysis with atomic force microscopy. Due to the nanoscale dimension of the in situ channel defined by the tip size, we probe a few monovacancy defects at a time. Monovacancy defects exhibit switching between three distinct ionization configurations, corresponding to charge states 0, -1, and -2. The most probable charge configurations are 0 and -1, providing a plausible mechanism to explain the observed anomalies of MoS<sub>2</sub> monolayers.
Nondestructive Evaluation Method of Welding Residual Stresses by Heating Method (2004)

In this paper, a new method of estimating welding residual stresses nondestructively is presented. From the strain changes on the surface due to the local change of Young modulus, distributions of eigenstrain are determined by the inverse analysis. Residual stresses are then evaluated by the elastic FEM analysis by using the eigenstrain as initial condition. Since the local change of Young modulus are due to temperature dependency by heating, we refered to the method as heating method. The method is used to estimate the residual stress distribution in a plate formed by joining two sections with a butt weld. The results show that the proposed method is robust, efficient and accurate. In this procedure, the simulated measured strains are generated by adding random error to the strain response form the solution of the direct solution, and the singular value decomposition method is used as a regularization method. The effects of number of sensors and their locations, the magnitude of measurement errors on the accuracy of estimations are investigated.

Simulation in a CIM environment (1988)

Simulation has long been recognized as a valuable tool for analyzing manufacturing systems. It is effective for assessing the impact of changing system parameters (e.g. reducing processing time) upon system performance measures, and it can also aid decisions concerning system configuration. At Penn State, simulation is playing an important role in the development of a Computer Integrated Manufacturing Laboratory. Currently, it is being used as an analysis tool studying system design and computer communication issues. Future plans are to use simulation as a real-time scheduling and control tool. Due to this ultimate long-term goal of the simulation model use, the model structure is different than traditional manufacturing applications of simulation. Rather than having events associated with workpiece movement and processing drive the simulation, computer communication events drive the model. This paper first discusses the general considerations involved when applying simulation as an analysis tool and potential real-time control tool in the CIM environment. The paper then discusses these analysis and real-time control issues in detail using the Penn State CIM Lab application as an illustrative example.
The Effect of Pudilan Anti‐Inflammatory Oral Liquid on the Treatment of Mild Recurrent Aphthous Ulcers (2017)

Recurrent aphthous ulcers are the most common recurrent oral mucosal lesions characterized by recurrence and pain. The aim of this research is to evaluate the short-term curative effect of the traditional Chinese medicine "Pudilan anti-inflammatory oral liquid" on mild recurrent aphthous ulcers. A total of 234 patients were divided into a treatment group and a control group. Both groups used vitamin B<sub>2</sub> as the basis of treatment. The treatment group took a Pudilan anti-inflammatory oral solution for 8 days while the control group was given a liquid placebo. The ulcer size, pseudomembrane, peripheral congestion, and pain scores of the treatment group were lower than before treatment. The curative effect on the Pudilan group was statistically significant compared with the control group. The final therapeutic effect on the treatment group was better than that on the control group. The healing time of mild recurrent aphthous ulcers can be shortened by Pudilan anti-inflammatory oral liquid, and pain is relieved without adverse reactions. Pudilan provides a new reference drug for the treatment of mild recurrent oral ulcers.
Domain wall traps for low-field switching of submicron elements (2000)

In magnetic random access memory, power consumption depends on the coercivity of the magnetic elements in the memory cells. In this article a new method is described that uses a “domain wall trap” element shape to reduce both the coercivity and the dependence of coercivity on element size in submicron magnetic elements. Micromagnetic simulations of a shaped permalloy element show coercivity less than one tenth the coercivity calculated for a rectangular permalloy element of the same size. The switching times for the domain wall traps are shown to be comparable to those of rectangular elements.
A 12-bit high performance low cost pipeline ADC (2004)

This paper presents the design and implementation of a 2.5V 12-bit high performance and low cost pipeline Analog-to-Digital converter (ADC) architecture using CMOS technology. A modified flash ADC was employed instead of the traditional flash ADC to implement the sub-ADC in the designed pipeline ADC scheme to reduce the device complexity and attain lower system power consumption. The designed pipeline ADC architecture is operated at 400 MHz, consumes a total power of 47.7mW. Results indicates that 40% power saving is obtained at 400MHz when the modified flash ADC is used to implement the pipeline sub-ADC instead of a full flash ADC. Such pipeline ADC is the best candidate for many applications where power and size are the major factors.
Histochemical and fatigue characteristics of conditioned canine latissimus dorsi muscle. (1986)

To induce fatigue resistance in the latissimus dorsi muscle of the dog in preparation for possible myocardial assistance, eight adult male beagles underwent unilateral electrical stimulation of the thoracodorsal nerve at a frequency of 2 Hz (120 stimuli/min) and 10 Hz (600 stimuli/min) for a 6-week period. The conditioned muscles were compared with their unconditioned contralateral controls by fiber typing, pyrophosphate gel electrophoresis, isometric characteristics, and fatigue rates. At the end of the period of stimulation, the conditioned muscles had a greater percentage of slow-twitch, fatigue-resistant fibers on acid and alkaline stains (100 +/- 0.7% and 83 +/- 15.3%), respectively, than did their contralateral controls (45 +/- 7.6% and 43 +/- 7.0). Pyrophosphate gel electrophoresis revealed an increase in the slow myosin and a decrease in the fast myosin content in the conditioned muscles; the stimulated muscles also demonstrated a slower contraction time (87 +/- 20 msec vs. 57 +/- 17.9 msec), a lower initial tension (4.4 +/- 1.45 kg vs. 7.2 +/- 2.11 kg), and a slower fatigue rate during a 30-minute fatigue test than did their contralateral controls. The muscles stimulated at 2 Hz had fatigue rates similar to those stimulated at 10 Hz, but generally had less diminution in muscle fiber diameters and less interfiber connective tissue. Thus, it is possible to make canine latissimus dorsi muscles more fatigue resistant, and, theoretically, more capable of myocardial assistance by electrical stimulation of the thoracodorsal nerve at a frequency as low as 2 Hz--the natural canine heart rate.

Halogenbrücken erhöhen Affinität: Für eine Serie kovalenter Inhibitoren von humanem Cathepsin L wurde zunehmende Bindungsaffinität gefunden, wenn ein Arylringproton durch Cl, Br oder I ersetzt wurde, die Halogenbrücken mit der CO-Gruppe von Gly61 in der S3-Tasche des Enzyms eingehen. Fluor hingegen meidet Halogenbrücken eindeutig (siehe Schema). Die starke Abstands- und Winkelabhängigkeit von Halogenbrücken wurde für biologische Systeme bestätigt.
Review of Recent Inkjet-Printed Capacitive Tactile Sensors (2017)

Inkjet printing is an advanced printing technology that has been used to develop conducting layers, interconnects and other features on a variety of substrates. It is an additive manufacturing process that offers cost-effective, lightweight designs and simplifies the fabrication process with little effort. There is hardly sufficient research on tactile sensors and inkjet printing. Advancements in materials science and inkjet printing greatly facilitate the realization of sophisticated tactile sensors. Starting from the concept of capacitive sensing, a brief comparison of printing techniques, the essential requirements of inkjet-printing and the attractive features of state-of-the art inkjet-printed tactile sensors developed on diverse substrates (paper, polymer, glass and textile) are presented in this comprehensive review. Recent trends in inkjet-printed wearable/flexible and foldable tactile sensors are evaluated, paving the way for future research.
A unique vaccine for control of fertility and therapy of advanced‐stage terminal cancers ectopically expressing human chorionic gonadotropin (2013)

Human chorionic gonadotropin (hCG) appears soon after fertilization of the egg and plays a critical role in implantation of the embryo leading to the beginning of pregnancy. Vaccines developed against hCG prevent pregnancy without impairment of ovulation and disturbance of menstrual regularity. A new recombinant vaccine hCGβ-LTB has been developed that is highly immunogenic in various strains of mice and intended for the control of fertility in women. An additional use of this vaccine is likely to be treatment of advanced-stage cancers that ectopically express hCG.
Phosphorescence Color Tuning of Cyclometalated Iridium Complexes by <i>o</i>-Carborane Substitution (2012)

Heteroleptic (C(^)N)(2)Ir(acac) (C(^)N = 4-CBppy (1); 5-CBppy (2), 4-fppy (4) CB = ortho-methylcarborane; ppy = 2-phenylpyridinato-C(2),N, 4-fppy = 2-(4-fluorophenyl)pyridinato-C(2),N, acac = acetylacetonate) complexes were prepared and characterized. While 1 exhibits a phosphorescence band centered at 531 nm, which is red-shifted compared to that of unsubstituted (ppy)(2)Ir(acac) (3) (λ(em) = 516 nm), the emission spectrum of 2 shows a blue-shifted band at 503 nm. Comparison with the emission band for the 4-fluoro-substituted 4 (λ(em) = 493 nm) indicates a substantial bathochromic shift in 1. Electrochemical and theoretical studies suggest that while carborane substitution on the 4-position of the phenyl ring lowers the (3)MLCT energy by a large contribution to lowest unoccupied molecular orbital (LUMO) delocalization, which in turn assigns the lowest triplet state of 1 as [d(π)(Ir)→π*(C(^)N)] (3)MLCT in character, the substitution on the 5-position raises the (3)MLCT energy by the effective stabilization of the highest occupied molecular orbital (HOMO) level because of the strong inductive effect of carborane. An electroluminescent device incorporating 1 as an emitter displayed overall good performance in terms of external quantum efficiency (6.6%) and power efficiency (10.7 lm/W) with green phosphorescence.
Role of <i>FHIT</i> in Human Cancer (1999)

Through investigation of hemizygous and homozygous deletions in common human cancers, including lung cancer, we have cloned and characterized a gene at chromosome region 3p14.2, FHIT, that is inactivated in epithelial tumors, particularly in tumors resulting from exposure to environmental carcinogens. In some tumors, particularly those associated with environmental carcinogens, alterations in the FHIT gene occur quite early in the development of cancer. In other cancers, Fhit inactivation seems to be a later event, possibly associated with progression to more aggressive neoplasias. Thus, detection of Fhit expression by immunohistochemistry in premalignant and malignant tissues may provide important diagnostic and prognostic information.

Diagnosis of Breast Cancer Using Ultrasound (2013)

Improvements in technology over the past 20 years have made real-time ultrasonography (US) an important imaging modality for evaluation of breast lumps and detection of breast cancer. Considerable advancements in US image quality and ultrasonic tissue characterization have taken place due to improvements in the resolution of high-frequency transducers, and development of color Doppler US (CDU) technology, tissue harmonic imaging, and various image processing techniques. The use of hand-held high-resolution real-time scanners operating at frequencies of 7.5–15 MHz (or even higher) with a penetrating depth of about 6 cm has become fairly standard among practitioners. State-of-the-art scanners with advanced US technology have significantly contributed to the improvements in spatial and contrast resolution. Physicians who are facing an increasing incidence of breast cancer in Asia and even in western countries are now becoming aware of the usefulness of breast US. Familiarity with the diagnostic accuracy and commonly used lexicon in breast US is helpful for physicians during communication with diagnostic imaging experts, breast surgeons, and patients.
