What's Feedback Got To Do With It? Examining Learning Rate and Generalization in Cross-scene Statistical Learning With and Without Feedback (2013)

Most models of learning predict that the presence of feedback facilitates the rate of learning, but can inhibit generalization by emphasizing attested exemplars rather than underlying rules. In a task where participants can learn statistical information without feedback (statistical learning), we examined what additional role feedback plays in learning and generalization. Following Shohamy and Wagner (2008), participants were taught arbitrary face-scene associations. On every trial, participants saw simultaneous presentation of a face and two scenes. After selecting one of the two scenes in a fixed response interval, participants were either given feedback (N=16, picture of a thumbs-up or -down) or not (N=19). Unbeknownst to participants, every two faces (Face1, Face2) were reciprocally paired with two scenes (Scene1, Scene2) creating a family of 4 overlapping associations (e.g. Face1—Scene1, Face1—Scene2, Face2—Scene1, Face2—Scene2). During training (4 blocks), participants were exposed to 3 of the 4 possible associations for each of the 16 families (trained associations). At test, feedback was always withheld to test for trained associations and untrained associations (generalization associations). There were robust and nearly identical learning rates for trained associations across feedback conditions. Both groups readily generalized but with marginally more generalization in the feedback condition (p <0.1). We find no significant difference in the frequency of non-learners across groups (defined as participants who fail to exhibit significant learning in any training block, feedback: N=2, no-feedback: N=6). Overall, these results show that learning of scene-pair associations and generalization to unseen, overlapping associations is minimally affected by the presence of feedback. In contrast to previous models, these results suggest that in the presence of salient statistical information, feedback may not modulate the time-course and outcomes of learning. Future work will examine how individual differences in the exposure phase affect learning rates and the factors that predict non-learners. Meeting abstract presented at VSS 2013

Immunoneutralization of Nerve Growth Factor in Lumbosacral Spinal Cord Reduces Bladder Hyperreflexia in Spinal Cord Injured Rats. (2002)

Increased levels of NGF in the bladder, spinal cord and dorsal root ganglia were associated with bladder hyperreflexia after spinal cord injury. Immuno-neutralization of NGF in the spinal cord suppressed NGF levels in the L6 to S1 dorsal root ganglia, which contain bladder afferent neurons, and also suppressed bladder hyperreflexia. Thus, suppression of NGF levels in afferent pathways could be useful for treating bladder hyperreflexia associated with spinal cord injury.
Mobile PCIS: Point-of-Care Information Systems with Portable Terminals (1998)

We have developed a Point-of-Care Information System (PCIS) that uses portable terminals and supports the entire loop of daily nursing work for the first time. Nursing work includes a great deal of indirect nursing work, such as documenting patient information, conferring with other health-care providers, and so on, as well as direct patient care. The time needed for this indirect work often exceeds the time actually spent directly caring for patients and needs to be reduced Our system was developed with the goal of doing this to make nursing work more efficient. The system consists of personal digital assistants (PDAs) that nurses carry in the hospital wards and a server computer located in the nursing station. The system has three main functions: 1) Data Browsing provides patient information such as a brief history, vital-sign charts, and handwritten notes; 2) Schedule Planning helps nurses organize doctors&amp;apos; instructions and make To-do lists for the day; and 3) Care Management reminds nurses when they should execute the doctors&amp;apos; orders and provides tools for data entry. These three functions cover the entire loop of daily nursing work. The PDAs and the server computer can share up-to-date information by data transmission through telephone lines (low-power cellular phones can be used), infrared devices, or RS-232C cables. Results from a preliminary hospital evaluation showed that use of the system can reduce the time needed for nursing documentation by 60% (a 10% saving of a nurse&amp;apos;s total working time), and that more than 80% of the nurses who used the system felt it would make nursing work more efficient.
Weak Intermolecular Interactions in Covalent Organic Framework-Carbon Nanofiber Based Crystalline yet Flexible Devices (2019)

The redox-active and porous structural backbone of covalent organic frameworks (COFs) can facilitate high-performance electrochemical energy storage devices. However, the utilities of such 2D materials as supercapacitor electrodes in advanced self-charging power-pack systems have been obstructed due to the poor electrical conductivity and subsequent indigent performance. Herein, we report an effective strategy to enhance the electrical conductivity of COF thin sheets through the in situ solid-state inclusion of carbon nanofibers (CNF) into the COF precursor matrix. The obtained COF-CNF hybrids possess a significant intermolecular π···π interaction between COF and the graphene layers of the CNF. As a result, these COF-CNF hybrids (DqTp-CNF and DqDaTp-CNF) exhibit good electrical conductivity (0.25 × 10<sup>-3</sup> S cm<sup>-1</sup>), as well as high performance in electrochemical energy storage (DqTp-CNF: 464 mF cm<sup>-2</sup> at 0.25 mA cm<sup>-2</sup>). Also, the fabricated, mechanically strong quasi-solid-state supercapacitor (DqDaTp-CNF SC) delivered an ultrahigh device capacitance of 167 mF cm<sup>-2</sup> at 0.5 mA cm<sup>-2</sup>. Furthermore, we integrated a monolithic photovoltaic self-charging power pack by assembling DqDaTp-CNF SC with a perovskite solar cell. The fabricated self-charging power pack delivered excellent performance in the areal capacitance (42 mF cm<sup>-2</sup>) at 0.25 mA cm<sup>-2</sup> after photocharging for 300 s.

Laser optical gas sensor by photoexcitation effect on refractive index (2010)

Laser optical gas sensors are fabricated by using the crystalline silicon carbide polytype 6H-SiC, which is a wide-bandgap semiconductor, and tested at high temperatures up to 650 degrees C. The sensor operates on the principle of semiconductor optics involving both the semiconductor and optical properties of the material. It is fabricated by doping 6H-SiC with an appropriate dopant such that the dopant energy level matches the quantum of energy of the characteristic radiation emitted by the combustion gas of interest. This radiation changes the electron density in the semiconductor by photoexcitation and, thereby, alters the refractive index of the sensor. The variation in the refractive index can be determined from an interference pattern. Such patterns are obtained for the reflected power of a He-Ne laser of wavelength 632.8 nm as a function of temperature. SiC sensors have been fabricated by doping two quadrants of a 6H-SiC chip with Ga and Al of dopant energy levels E(V)+0.29 eV and E(V)+0.23 eV, respectively. These doped regions exhibit distinct changes in the refractive index of SiC in the presence of carbon dioxide (CO(2)) and nitrogen monoxide (NO) gases respectively. Therefore Ga- and Al-doped 6H-SiC can be used for sensing CO(2) and NO gases at high temperatures, respectively.
Compiler support for garbage collection in a statically typed language (1992)

We consider the problem of supporting compacting garbage collection in the presence of modern compiler optimizations. Since our collector may move any heap object, it must accurately locate, follow, and update all pointers and values derived from pointers. To assist the collector, we extend the compiler to emit tables describing live pointers, and values derived from pointers, at each program location where collection may occur. Significant results include identification of a number of problems posed by optimizations, solutions to those problems, a working compiler, and experimental data concerning table sizes, table compression, and time overhead of decoding tables during collection. While gc support can affect the code produced, our sample programs show no significant changes, the table sizes are a modest fraction of the size of the optimized code, and stack tracing is a small fraction of total gc time. Since the compiler enhancements are also modest, we conclude that the approach is practical.

Prostate Cancer Pulmonary Metastasis Presenting as a Ground-Glass Pulmonary Nodule on 68Ga-PSMA-11 PET/CT (2019)

Ga-prostate-specific membrane antigen 11 (PSMA) PET/CT imaging accurately depicts metastatic prostate adenocarcinoma (PCa). Pulmonary metastases of PCa are often overlooked on follow-up imaging in patients after initial treatment and following androgen deprivation therapy. Here we present a rare case of biopsy-proven PCa pulmonary metastasis with a ground-glass appearance. The increased PSMA expression and the evolving CT features of the solid component of the ground-glass nodule detected by PSMA PET/CT imaging led to surgical resection and PET/CT-guided therapy.
Author response: Mucosal infection rewires TNFɑ signaling dynamics to skew susceptibility to recurrence (2019)

Polarizing susceptibilities to recurrent bladder infection are shaped by a duality in TNFɑ-mediated inflammation dynamics upon challenge infection that is dictated by the outcome of the initial infection.
Measurement of the Top Quark Mass Using Dilepton Events (1998)

The D0 Collaboration has performed a measurement of the top quark mass ${m}_{t}$ based on six candidate events for the process $t\overline{t}\ensuremath{\rightarrow}{\mathrm{bW}}^{+}\overline{b}{W}^{\ensuremath{-}}$, where the $W$ bosons decay to $e\ensuremath{\nu}$ or $\ensuremath{\mu}\ensuremath{\nu}$. This sample was collected during an exposure of the D0 detector to an integrated luminosity of $125{\mathrm{pb}}^{\ensuremath{-}1}$ of $\sqrt{s}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}1.8\phantom{\rule{0ex}{0ex}}\mathrm{TeV}p\overline{p}$ collisions.

Anti-reflux surgery in lung transplant recipients: outcomes and effects on quality of life (2011)

Fundoplication may improve survival after lung transplantation. Little is known about the effects of fundoplication on quality of life in these patients. The aim of this study was to assess the safety of fundoplication in lung transplant recipients and its effects on quality of life. Between June 1, 2008 and December 31, 2010, a prospective study of lung transplant recipients undergoing fundoplication was undertaken. Quality of life was assessed before and after surgery. Body mass index (BMI) and pulmonary function were followed up. 16 patients, mean ± sd age 38 ± 11.9 yrs, underwent laparoscopic Nissen fundoplication. There was no peri-operative mortality or major complications. Mean ± SD hospital stay was 2.6 ± 0.9 days. 15 out of 16 patients were satisfied with the results of surgery post fundoplication. There was a significant improvement in reflux symptom index and DeMeester questionnaires and gastrointestinal quality of life index scores at 6 months. Mean BMI decreased significantly after fundoplication (p = 0.01). Patients operated on for deteriorating lung function had a statistically significant decrease in the rate of lung function decline after fundoplication (p = 0.008). Laparoscopic fundoplication is safe in selected lung transplant recipients. Patient benefit is suggested by improved symptoms and satisfaction. This procedure is acceptable, improves quality of life and may reduce deterioration of lung function.
Selective-tap adaptive algorithms in the solution of the nonuniqueness problem for stereophonic acoustic echo cancellation (2005)

We investigate stereophonic acoustic echo cancellation in which solutions for the system can be nonunique and propose the use of selective-tap adaptive filters to address this problem. The main concept is to employ tap selection to optimize jointly for minimum interchannel coherence and maximum L/sub 2/-norm of the subselected tap-input vectors. The exclusive maximum (XM) tap-selection approach is proposed and applied to normalized least-mean squares (NLMS) and recursive least-squares (RLS) algorithm. We propose an approach for solving the nonuniqueness problem employing XM tap selection in combination with a nonlinear preprocessor. Simulation results show a significant improvement in convergence rate compared with existing techniques.

A PDMS sample pretreatment microdevice to enable downstream electrokinetic manipulations in bovine serum (2010)

The notion of sample preconditioning, or pretreatment, as a micro-unit operation in a Lab on a Chip (LOC) system has yet to be realized in commercial practice. As is well known, Biomarker detection in complex, biological samples, such as blood, requires a series of pretreatment steps to enable detection of specific markers. On chip, such a process usually relies on "off-chip" sample pretreatment prior to "on-chip" analyte manipulations and detection. Presented in this paper is a PDMS, pretreatment chip based on the design of Oddy et al.1 with a view to enable a self-contained LOC platform. The chip was designed to directly manipulate the suspended species while adjusting fluid properties using buffer volumes less than 1 ml. Using previous literature related to capillary electrophoresis, a bench-scale pretreatment protocol was developed to tune specific fluidic parameters to an optimal range, namely pH, conductivity, and viscosity. A PDMS device was fabricated and used to combine a raw, bovine serum sample with specific buffer solutions. Off-chip electrodes were used to induce DC-electrokinetic micro-mixing of the target analyte in the mixing chamber, where a homogeneous analyte distribution was achieved in less than one second using an 800V DC pulse wave. Additionally, the desired solution viscosity and pH were achieved using less than 1 ml of buffer solution. Adjustment of sample conductivity, which is driven by sample fluid volume, remains an open area of research.
Enzyme immunoassay using a novel recombinant polypeptide to detect human immunodeficiency virus env antibody (1987)

A unique antigen, CBre3, has been synthesized from a genetically engineered clone to detect human immunodeficiency virus (HIV) env antibodies with high sensitivity and specificity. The antigen contains sequences derived from both envelope proteins of HIV, i.e., gp120 and gp41, and was purified free of Escherichia coli proteins detectable by Coomassie stain or immunoblotting with E. coli antiserum. The purified recombinant polypeptides were used as antigen in an enzyme immunoassay (EIA) to screen serum samples from healthy and HIV-infected individuals. The same samples were also tested by radioimmunoprecipitation (RIP) for gp120 and gp160 HIV antibodies. All samples containing gp120 and gp160 antibodies by RIP had CBre3 EIA values greater than 0.35 (n, 122; range, 0.37 to 2.1+; median, 1.65). All RIP HIV antibody-negative samples had CBre3 EIA values less than 0.25 (n, 140; mean, 0.052; standard deviation, 0.045; range, 0.00 to 0.22). The endpoint titer of a standard positive control serum was 1:10,000 by RIP and by CBre3 EIA. The assay was 100% accurate in three proficiency panels. It easily detected six samples from individuals whose infections were confirmed by culture; these samples were reactive only with p24 by Western blot. The samples also were positive for gp120 and gp160 antibodies by RIP. These data suggest that the CBre3 EIA can detect env antibodies as sensitively and specifically as RIP and with more sensitivity than Western blot.
Simultaneous Determination of Chlorinated Ethenes and Ethene in Groundwater Using Headspace Solid-Phase Microextraction with Gas Chromatography (2013)

Widespread contamination of groundwater by chlorinated ethenes and their biological dechlorination products necessitates the reliable monitoring of liquid matrices; current methods approved by the U.S. Environmental Protection Agency (EPA) require a minimum of 5 mL of sample volume and cannot simultaneously detect all transformative products. This paper reports on the simultaneous detection of six chlorinated ethenes and ethene itself, using a liquid sample volume of 1 mL by concentrating the compounds onto an 85-µm carboxen-polydimenthylsiloxane solid-phase microextraction fiber in 5 min and subsequent chromatographic analysis in 9.15 min. Linear increases in signal response were obtained over three orders of magnitude (∼0.05 to ∼50 µM) for simultaneous analysis with coefficient of determination (R(2)) values of ≥ 0.99. The detection limits of the method (1.3-6 µg/L) were at or below the maximum contaminant levels specified by the EPA. Matrix spike studies with groundwater and mineral medium showed recovery rates between 79-108%. The utility of the method was demonstrated in lab-scale sediment flow-through columns assessing the bioremediation potential of chlorinated ethene-contaminated groundwater. Owing to its low sample volume requirements, good sensitivity and broad target analyte range, the method is suitable for routine compliance monitoring and is particularly attractive for interpreting the bench-scale feasibility studies that are commonly performed during the remedial design stage of groundwater cleanup projects.
Haute couture for transcription's next top model: text processing technologies on the catwalk (2005)

Summary form only given. The top model metaphor refers to forward-looking applications expected to come of age in the next few years. They are likely to involve the large-scale automatic transcription of lectures, meetings, podcasts, oral histories, etc. In the realm of podcasting alone, free-form content searching could quickly become critical at the current growth rate of the medium. Such applications entail many speech recognition challenges, which John Hansen comprehensively covers in the first talk of the forum. But they also raise a number of issues which are somewhat orthogonal to the process of transcription itself. This talk, accordingly, serves as a catwalk presentation of the various component technologies involved. It points to recent work in each area, highlights major bottlenecks, covers promising solutions, suggests some new areas of research, and offers some perspectives regarding comparative merits and associated trade-offs
Colonial Immigrants in a British City (2022)

Colonial Immigrants in a British City (1979) analyses the relationship between West Indian and Asian immigrants and the class structure of a British city. Based on a four-year research project in the Handsworth area of Birmingham, the book is a study of race and community relations – political, social, economic and personal – in a major centre of immigrant settlement. It considers the relationship between housing class and class formations and consciousness in other sectors of allocation, such as employment and education. It includes a consideration of the changing political climate on race relations between 1950 and 1976.
