Decrease in force steadiness with aging is associated with increased power of the common but not independent input to motor neurons (2018)

Declines in motor function with advancing age have been attributed to changes occurring at all levels of the neuromuscular system. However, the impact of aging on the control of muscle force by spinal motor neurons is not yet understood. In this study on 20 individuals aged between 24 and 75 yr (13 men, 7 women), we investigated the common synaptic input to motor neurons of the tibialis anterior muscle and its impact on force control. Motor unit discharge times were identified from high-density surface EMG recordings during isometric contractions at forces of 20% of maximal voluntary effort. Coherence analysis between motor unit spike trains was used to characterize the input to motor neurons. The decrease in force steadiness with age ( R<sup>2</sup> = 0.6, P < 0.01) was associated with an increase in the amplitude of low-frequency oscillations of functional common synaptic input to motor neurons ( R<sup>2</sup> = 0.59; P < 0.01). The relative proportion of common input to independent noise at low frequencies increased with variability (power) in common synaptic input. Moreover, variability in interspike interval did not change and strength of the common input in the gamma band decreased with age ( R<sup>2</sup> = 0.22; P < 0.01). The findings indicate that age-related reduction in the accuracy of force control is associated with increased common fluctuations to motor neurons at low frequencies and not with an increase in independent synaptic input. NEW & NOTEWORTHY The influence of aging on the role of spinal motor neurons in accurate force control is not yet understood. We demonstrate that aging is associated with increased oscillations in common input to motor neurons at low frequencies and with a decrease in the relative strength of gamma oscillations. These results demonstrate that the synaptic inputs to motor neurons change across the life span and contribute to a decline in force control.
Ground Filtering Algorithms for Airborne LiDAR Data: A Review of Critical Issues (2010)

This paper reviews LiDAR ground filtering algorithms used in the process of creating Digital Elevation Models. We discuss critical issues for the development and application of LiDAR ground filtering algorithms, including filtering procedures for different feature types, and criteria for study site selection, accuracy assessment, and algorithm classification. This review highlights three feature types for which current ground filtering algorithms are suboptimal, and which can be improved upon in future studies: surfaces with rough terrain or discontinuous slope, dense forest areas that laser beams cannot penetrate, and regions with low vegetation that is often ignored by ground filters.

Enhanced Long-term and Thermal Stability of Polymer Solar Cells in Air at High Humidity with the Formation of Unusual Quantum Dot Networks (2017)

Due to the practical applications of polymer solar cells (PSCs), their stability recently has received increasing attention. Herein, a new strategy was developed to largely enhance the long-term and thermal stability of PSCs in air with a relatively high humidity of 50-60% without any encapsulation. In this strategy, semiconductor PbS/CdS core/shell quantum dots (QDs) were incorporated into the photoactive blend of poly(3-hexylthiophene) (P3HT) and phenyl-C<sub>61</sub>-butyric acid methyl ester (PCBM). By replacing the initial ligands of oleic acid with halide ligands on the surface of PbS/CdS QDs via solution-phase ligand exchange, we were able to form unusual, continuous QD networks in the film of P3HT:PCBM, which effectively stabilized the photoactive layer. Air-processed PSCs based on the stabilized P3HT:PCBM film showed excellent long-term stability under high humidity, providing over 3% of power conversion efficiency (PCE) simultaneously. Around 91% of pristine PCE was retained after 30 days storage in high-humidity air without encapsulation. This constitutes a remarkable improvement compared to ∼53% retained PCE for the QD-free devices, which can be ascribed to the efficient suppression of both PCBM aggregation and oxidation of the thiophene ring in P3HT, thanks to the formation of robust QD networks. Furthermore, the presence of QD networks was able to enhance the stability of the P3HT:PCBM film against thermal stress/oxidation under high-humidity environment (50-60%) as well. The device kept 60% of pristine PCE after thermal treatment for 12 h at 85 °C in air, which is more than twice higher than that for the QD-free device. To the best of our knowledge, the work represents the first unambiguous demonstration of the formation of QD networks in the photoactive layer and of their important contribution to the stability of PSCs. This strategy is highly promising for other fullerene-based PSCs and opens a new avenue toward achieving PSCs with high PCE and excellent stability.

Evaluating an Automatically Scorable, Open‐Ended Response Type for Measuring Mathematical Reasoning in Computer‐Adaptive Tests (1997)

The first generation of computer‐based tests depends largely on multiple‐choice items and constructed‐response questions that can be scored through literal matches with a key. This study evaluated scoring accuracy and item functioning for an open‐ended response type where correct answers, posed as mathematical expressions, can take many different surface forms. Items were administered to 1,864 participants in field trials of a new admissions test for quantitatively oriented graduate programs. Results showed automatic scoring to approximate the accuracy of multiple‐choice scanning, with all processing errors stemming from examinees improperly entering responses. In addition, the items functioned similarly in difficulty, item‐total relations, and male‐female performance differences to other response types being considered for the measure.
Impact of Signature Legibility and Signature Type in Off-Line Signature Verification (2007)

The performance of two popular approaches for off-line signature verification in terms of signature legibility and signature type is studied. We investigate experimentally if the knowledge of letters, syllables or name instances can help in the process of imitating a signature. Experimental results are given on a sub-corpus of the MCYT signature database for random and skilled forgeries. We use for our experiments two machine experts, one based on global image analysis and statistical distance measures, and the second based on local image analysis and Hidden Markov Models. Verification results are reported in terms of Equal Error Rate (EER), False Acceptance Rate (FAR) and False Rejection Rate (FRR).
[Liquid flow field measurement in a tube with a combination of stenosis and bifurcation]. (2006)

Two-D liquid velocity field in a tube with a combination of a stenosis and a bifurcation was measured with refractive index matching technique using Laser Doppler Velocimeter (LDV). The flow ratio of main tube to bypass was 1:4. It is found that the axial velocity profile has two peaks in the XOY plane which is skewed to the main tube wall facing the flow from the bypass, and it manifests itself in the form of "M" in the XOZ plane. A two counter-rotating vortices in the main tube cross section downstream the conjunction region is also detected.
The Effect of Rearing Density on Growth, Survival, and Feed Conversion of Juvenile Atlantic Sturgeon (2002)

We investigated the effect of rearing density on the growth and survival of juvenile Atlantic sturgeon Acipenser oxyrinchus using initial rearing densities ranging from 10 to 30 fish per tank or 3.6–10.9 kg/m2 of substrate. The mean weight of fish at the start of the trial was 368.7 g. After 7 weeks of rearing, density ranged from 6.5 to 16.3 kg/m2 (14.7–36.6 g/L). Fish reared at the lowest density had significantly higher mean weight and length at the end of the trial. Growth over the 7-week experiment was modeled as a function of time, and growth rate was inversely proportional to density. The mean increase in total biomass was 63.14%, and the mean daily length gain was 0.23%. Overall survival was 99.7%, and calculated feed conversion rates ranged from 1.93 to 2.65. However, feed conversion rates were likely not at maximum levels due to the selection of a relatively high experimental feeding rate (2.5% of body weight per day).
Functionalized screen-printed electrodes for the thermal detection of Escherichia coli in dairy products (2022)

Accurate and fast on-site detection of harmful microorganisms in food products is a key preventive step to avoid food-borne illness and product recall. In this study, screen-printed electrodes (SPEs) were functionalized via a facile strategy with surface imprinted polymers (SIPs). The SIP-coated SPEs were used in combination with the heat transfer method (HTM) for the real-time detection of Escherichia coli. The sensor was tested in buffer, with a reproducible and sensitive response that attained a limit of detection of 180 CFU/mL. Furthermore, selectivity was assessed by analyzing the sensor's response to C. sakazakii, K. pneumoniae and S. aureus as analogue strains. Finally, the device was successfully used for the detection of E. coli in spiked milk as proof-of-application, requiring no additional sample preparation. These results suggest the proposed thermal biosensor possesses the potential of becoming a tool for routine, on-site monitoring of E. coli in food safety applications.
Electrospinning of Highly Porous Scaffolds for Cartilage Regeneration (2008)

This study presents a new innovative method where electrospinning is used to coat single microfibers with nanofibers. The nanofiber-coated microfibers can be formed into scaffolds with the combined benefits of tailored porosity for cellular infiltration and nanostructured surface morphology for cell growth. The nanofiber coating is obtained by using a grounded collector rotating around the microfiber, to establish an electrical field yet allow collection of nanofibers on the microfiber. A Teflon tube surrounding the fibers and collector is used to force the nanofibers to the microfiber. Polycaprolactone nanofibers were electrospun onto polylactic acid microfibers and scaffolds of 95 and 97% porosities were made. Human chondrocytes were seeded on these scaffolds and on reference scaffolds of purely nanofibers and microfibers. Thereafter, cellular infiltration was investigated. The results indicated that scaffold porosity had great effects on cellular infiltration, with higher porosity resulting in increased infiltration, thereby confirming the advantage of the presented method.
Physicochemical characterizations and dissolution behavior of curcumin and α-cyclodextrin molecular inclusion complexes (2014)

The aim of present work was to enhance the aqueous solubility and dissolution rate of the curcumin, a water insoluble yellow colored phenolic pigment with good anti-inflammatory property obtained from dried rhizomes of plant Cucrcuma longa. This paper presents physicochemical evaluations of curcumin and its molecular inclusion complexes with α-cyclodextrin. Phase solubility studies revealed linear relationships (AL type) indicating 1:1 ratios of curcumin and α-cyclodextrin. Based upon the stoichiometric ratio as obtained from phase solubility studies, solid inclusion complexes were prepared by grinding, kneading and freeze drying methods and then investigated by differential scanning calorimetry (DSC), infra red spectroscopy (IR) and X-ray diffractometry (XRD). All tested curcumin complexes behaved as amorphous solid mixture in XRD and FT IR investigations. Prepared inclusion complexes were compared with pure curcumin for their dissolution behavior. Dissolution study revealed 10.5% release of curcumin at 1 hour and a maximum of 40.9% release was obtained by the end of 6 hours, which was due to poor water solubility of curcumin. In contrast, curcumin complexes demonstrated faster and better release behaviors. At least 3 fold increases in dissolution of all tested complexes were observed at one hour as compared to pure curcumin, with a maximum increase of approximately 3.5 fold as shown by kneaded and freeze dried complexes. At the end of 6 hours, approximately 60-65% release was observed from all inclusion complexes with a maximum release of 65% exhibited by freeze dried complex. Cyclodextrin complexation of curcumin enhanced dissolution of practically insoluble curcumin.

The diversity of three-dimensional photonic crystals (2021)

Many butterflies, birds, beetles, and chameleons owe their spectacular colors to the microscopic patterns within their wings, feathers, or skin. When these patterns, or photonic crystals, result in the omnidirectional reflection of commensurate wavelengths of light, it is due to a complete photonic band gap (PBG). The number of natural crystal structures known to have a PBG is relatively small, and those within the even smaller subset of notoriety, including diamond and inverse opal, have proven difficult to synthesize. Here, we report more than 150,000 photonic band calculations for thousands of natural crystal templates from which we predict 351 photonic crystal templates - including nearly 300 previously-unreported structures - that can potentially be realized for a multitude of applications and length scales, including several in the visible range via colloidal self-assembly. With this large variety of 3D photonic crystals, we also revisit and discuss oft-used primary design heuristics for PBG materials.

Beginnings of Remote Handling at the RAL Spallation Neutron Source (1985)

Expenditure of funds and resources for remote maintenance systems traditionally are delayed until late in an accelerator's development. However, simple remote-surveillance equipment can be included early in facility planning to set the stage for future remote-handling needs and to identify appropriate personnel. Some basic equipment developed in the UK at the Spallation Neutron Source (SNS) that serves this function and that has been used to monitor beam loss during commissioning is described. A photograph of this equipment, positioned over the extractor septum magnet, is shown in Fig. 1. This method can serve as a pattern approach to the problem of initiating remote-handling activities in other facilities.
Using High-Bandwidth Voltage Amplifier to Emulate Grid-Following Inverter for AC Microgrid Dynamics Studies (2019)

AC microgrid is an attractive way to energize local loads due to remotely located renewable generation. The AC microgrid can conceptually comprise several grid-forming and grid-following power converters, renewable energy sources, energy storage and local loads. To study the microgrid dynamics, power-hardware-in-the-loop (PHIL)-based test setups are commonly used since they provide high flexibility and enable testing the performance of real converters. In a standard PHIL setup, different components of the AC microgrid exist as real commercial devices or electrical emulators or, alternatively, can be simulated using real-time simulators. For accurate, reliable and repeatable results, the PHIL-setup should be able to capture the dynamics of the microgrid loads and sources as accurately as possible. Several studies have shown how electrical machines, dynamic RLC loads, battery storages and photovoltaic and wind generators can be emulated in a PHIL setup. However, there are no studies discussing how a three-phase grid-following power converter with its internal control functions should be emulated, regardless of the fact that grid-following converters (e.g., photovoltaic and battery storage inverters) are the basic building blocks of AC microgrids. One could naturally use a real converter to represent such dynamic load. However, practical implementation of a real three-phase converter is much more challenging and requires special knowledge. To simplify the practical implementation of microgrid PHIL-studies, this paper demonstrates the use of a commercial high-bandwidth voltage amplifier as a dynamic three-phase power converter emulator. The dynamic performance of the PHIL setup is evaluated by identifying the small-signal impedance of the emulator with various control parameters and by time-domain step tests. The emulator is shown to yield the same impedance behavior as real three-phase converters. Thus, dynamic phenomena such as harmonic resonance in the AC microgrid can be studied in the presence of grid-following converters.
Current Distribution for the Metallization of Resistive Wafer Substrates under Controlled Geometric Variations (2006)

Current distribution simulation results are presented for the metallizaton of 200-mm resistive wafer substrates. A novel horizontal plating cell design that features an insulating hole and a wafer holder that is capable of varying the wafer position vertically during the metallization process is considered to improve the current distribution across the wafer substrate surface. Numerical analysis is used to investigate the influence of the insulating hole size, wafer position, and wafer movement during the deposition process on the current distribution and is compared to experimental data for copper deposition when possible.
Recent advances in the use of microfluidic technologies for single cell analysis (2017)

The inherent heterogeneity in cell populations has become of great interest and importance as analytical techniques have improved over the past decades. With the advent of personalized medicine, understanding the impact of this heterogeneity has become an important challenge for the research community. Many different microfluidic approaches with varying levels of throughput and resolution exist to study single cell activity. In this review, we take a broad view of the recent microfluidic developments in single cell analysis based on microwell, microchamber, and droplet platforms. We cover physical, chemical, and molecular biology approaches for cellular and molecular analysis including newly emerging genome-wide analysis.
Isolation of molecular probes associated with the chromosome 15 instability in the Prader-Willi syndrome. (1986)

Flow cytometry and recombinant DNA techniques have been used to obtain reagents for a molecular analysis of the Prader-Willi syndrome (PWS). HindIII total-digest libraries were prepared in lambda phage Charon 21A from flow-sorted inverted duplicated no. 15 human chromosomes and propagated on recombination-proficient (LE392) and recBC-, sbcB- (DB1257) bacteria. Twelve distinct chromosome 15-specific probes have been isolated. Eight localized to the region 15q11----13. Four of these eight sublocalized to band 15q11.2 and are shown to be deleted in DNA of one of two patients examined with the PWS. Heteroduplex analysis of two of these clones, which grew on DB1257 but not on LE392, revealed stem-loop structures in the inserts, indicative of inverted, repeated DNA elements. Such DNA repeats might account for some of the cloning instability of DNA segments from proximal 15q. Analysis of the genetic and physical instability associated with the repeated sequences we have isolated from band 15q11.2 may elucidate the molecular basis for the instability of this chromosomal region in patients with the PWS or other diseases associated with chromosomal abnormalities in the proximal long arm of human chromosome 15.
