Laser-induced periodic surface structure. II. Experiments on Ge, Si, Al, and brass (1983)

We report the results of a detailed investigation into the properties of the periodic damage structure that can be produced on nominally smooth surfaces of solids when they are irradiated with a single beam of intense laser radiation. The study is primarily concerned with extracting information from the Fourier transform of the damage structure as observed via the Fraunhofer diffraction pattern produced by reflecting a cw laser beam from the surface. In particular, the patterns produced in Ge, Si, Al, and brass by pulsed 1.06- and 0.53-\ensuremath{\mu}m radiation are compared as a function of the angle of incidence and polarization of the beam. We find that all materials contain similar and much more intricate detailed structure than has been previously appreciated. Whereas periodic ripple patterns oriented perpendicular to the polarization at near-normal incidence are commonly reported, the diffraction patterns reveal that in fact there exists a continuous distribution of periodic structure oriented at all angles with respect to the polarization. At near-normal incidence there are two dominant sets of "fringes" running perpendicular to the polarization, while for a $p$-polarized beam incident at &gt;35\ifmmode^\circ\else\textdegree\fi{} there exist three dominant periodic structures; two which run perpendicular to the polarization and one which is oriented parallel to it. For $s$-polarized light incident at angles &gt;35\ifmmode^\circ\else\textdegree\fi{} there are two dominant patterns which form a cross-hatched pattern with axes oriented at 45\ifmmode^\circ\else\textdegree\fi{} to the plane of incidence. A study of the evolution of the patterns on a shot-to-shot basis indicates that both the initial and laser-induced surface roughness play important roles in the evolution of the damage. We conclude with a comparison of our experimental results with those predicted by the theory developed in the preceding paper. Excellent agreement is found.
Compressed sensing embedded in an operational wireless sensor network to achieve energy efficiency in long-term monitoring applications (2014)

Compressed sensing (CS) is a powerful new data acquisition paradigm that seeks to accurately reconstruct unknown sparse signals from very few (relative to the target signal dimension) random projections. The specific objective of this study is to save wireless sensor energy by using CS to simultaneously reduce data sampling rates, on-board storage requirements, and communication data payloads. For field-deployed low power wireless sensors that are often operated with limited energy sources, reduced communication translates directly into reduced power consumption and improved operational reliability. In this study, acceleration data from a multi-girder steel-concrete deck composite bridge are processed for the extraction of mode shapes. A wireless sensor node previously designed to perform traditional uniform, Nyquist rate sampling is modified to perform asynchronous, effectively sub-Nyquist rate sampling. The sub-Nyquist data are transmitted off-site to a computational server for reconstruction using the CoSaMP matching pursuit recovery algorithm and further processed for extraction of the structure?s mode shapes. The mode shape metric used for reconstruction quality is the modal assurance criterion (MAC), an indicator of the consistency between CS and traditional Nyquist acquired mode shapes. A comprehensive investigation of modal accuracy from a dense set of acceleration response data reveals that MAC values above 0.90 are obtained for the first four modes of a bridge structure when at least 20% of the original signal is sampled using the CS framework. Reduced data collection, storage and communication requirements are found to lead to substantial reductions in the energy requirements of wireless sensor networks at the expense of modal accuracy. Specifically, total energy reductions of 10?60% can be obtained for a sensor network with 10?100 sensor nodes, respectively. The reduced energy requirements of the CS sensor nodes are shown to directly result in improved battery life and communication reliability.
Reconstructing points on a circle from labeled distances (2009)

In the labeled beltway problem, we are given a set of points with unknown coordinates, their clockwise or-dering around the circumference of a circle, and a col-oring of the edges between pairs of points. The goal is to embed the points around a unit circle while satis-fying the constraint that two incident edges have the same geodesic length on the circle if and only if they have the same color. We give a polynomial-time algo-rithm to find such an embedding or to determine that no such embedding exists. 1
Chain transfer polymerization of methyl methacrylate initiated by organolanthanide complexes (2000)

A novel chain transfer polymerization mediated by Cp*2 Sm(III) species and organic acids is described. The chain transfer polymerization involves the reaction of organic acids such as thiols or ketones with an active bond between samarium(III) and the enolate at a living chain end of poly(methyl methacrylate) (PMMA). This chain transfer reaction resulted in termination of the living chain end and the regeneration of the active initiator which would consist of (C5Me5)2Sm(III) and deprotonated organic acids. The chain transfer polymerization were confirmed by turnover numbers (TON). tert-Butyl thiol exhibited the chain transfer reactivity effectively to control the molecular weight of PMMA without decreasing of the polymer yield and the stereoregularity. As a result of this chain transfer polymerization, thermal and optical properties of the PMMA obtained were improved by the control of chain end groups or by reducing a large amount of the samarium initiator.
Hopper‐Shaped Crystals: Self‐Assembly in Hopper‐Shaped Crystals (Adv. Funct. Mater. 26/2020) (2020)

In article number 1908108, Wen Shang, Tao Deng, and co-workers show that the building blocks of crystals tend to attach at certain sites on the crystal surfaces, and the growth rates of these sites will be larger than those at the other sites. The selective growth leads to interfacial instability, which also results in the growth of hopper-shaped crystals.
Spurious Tone Suppression Techniques Applied to a Wide-Bandwidth 2.4 GHz Fractional-N PLL (2008)

This paper demonstrates that spurious tones in the output of a fractional- <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">N</i> PLL can be reduced by replacing the DeltaSigma modulator with a new type of digital quantizer and adding a charge pump offset combined with a sampled loop filter. It describes the underlying mechanisms of the spurious tones, proposes techniques that mitigate the effects of the mechanisms, and presents a phase noise cancelling 2.4 GHz ISM-band CMOS PLL that demonstrates the techniques. The PLL has a 975 kHz loop bandwidth and a 12 MHz reference. Its phase noise has a worst-case reference spur power of - 70 dBc and a worst-case in-band fractional spur power of -64 dBc.
Spectral Denoising for Accelerated Analysis of Correlated Ionic Transport (2021)

Computation of correlated ionic transport properties from molecular dynamics in the Green-Kubo formalism is expensive, as one cannot rely on the affordable mean square displacement approach. We use spectral decomposition of the short-time ionic displacement covariance to learn a set of diffusion eigenmodes that encode the correlation structure and form a basis for analyzing the ionic trajectories. This allows systematic reduction of the uncertainty and accelerate computations of ionic conductivity in systems with a steady-state correlation structure. We provide mathematical and numerical proofs of the method's robustness and demonstrate it on realistic electrolyte materials.
Video viewing preferences for HDR displays under varying ambient illumination (2009)

Recent high dynamic range (HDR) display devices provide significantly greater output brightness and dynamic range compared to conventional display technology. A possible concern for the extended use of HDR displays is the potential to cause visual fatigue. Furthermore, ambient illumination has a significant effect on the perception of the imagery displayed, and its impact on user preferences for brightness and contrast must be understood.

Immunoglobulin production in severe combined immunodeficient (SCID) mice reconstituted with human peripheral blood mononuclear cells (1992)

Immunodeficient C.B-17 scid/scid (SCID) mice were reconstituted with human peripheral blood mononuclear cells and analyzed for humoral immunity. The majority of adoptively transferred animals had serum levels of 1-4 mg/ml of human IgG 8-12 weeks after i.p. reconstitution with 20 x 10(6) PBMC, whereas the IgM and especially IgA concentrations were considerably lower. The half-lives of human IgG, IgM, and IgA in SCID mice were 12 days, 36, and 23 hours, respectively. Furthermore, IgA was rapidly secreted into bile indicating that the low IgA concentration was mainly caused by a high turnover rate. IgG subclass distribution in mouse serum was similar to that found in the donor serum. Irradiation with 3 Gy prior to adoptive transfer resulted in increased levels of human IgG early after reconstitution, whereas both IgM and IgA concentrations were impaired. A polyclonal serum Ig pattern was found 4 weeks after transfer of human cells later frequently followed by a predominance of oligoclonal bands. Unexpectedly, oligoclonal bands were also found using donors with a negative Epstein-Barr virus serology. Human cells were found to reside in the peritoneal cavity for several months. Within 2 weeks of reconstitution, human cells were also identified in lymphoid structures in the vicinity of the liver hilus with a later spread to other lymphoid organs. Homing of human cells to skin and gut was not seen.
Reduction of multipath-induced bias of GPS time-of-arrival (2003)

We investigate a blind method for cancelling the multipath effects, in order to improve the time-of-arrival estimate. Our approach uses early-late gate processing on an objective function derived from an adaptive FIR filter that attempts to match the crosscorrelation of the received signal with a multipath-free replica of the desired crosscorrelation. This method performs reasonably well, and decreases the bias by approximately a factor of 2, even in very stressing multipath environments.

SEWS (2018)

The rise of video streaming has placed significant demands on network infrastructure. These demands are most acutely felt in the wireless space where limited resources are available. Compounding the matter, most techniques for adapting to network dynamics have been developed with wired networks in mind thus making performance in congested wireless networks, especially WiFi, quite problematic. In this paper, we propose a novel cross-layer design to improve video bitrate selection by incorporating MAC layer information. We design a lightweight channel characterization method that can provide an accurate airtime estimation based on the observation of WiFi control packets. We then devise a bitrate adaptation algorithm that can judiciously avoid faulty bitrate increases whenever severe channel competition is detected. Through extensive lab experiments, we show that our proposed method can significantly reduce video stall rates by up to 30x (from 65% to 2%) compared to existing methods.
High Frequency of the p.R34X Mutation in the TMC1 Gene Associated with Nonsyndromic Hearing Loss Is Due to Founder Effects (2010)

Founder mutations, particularly 35delG in the GJB2 gene, have to a large extent contributed to the high frequency of autosomal recessive nonsyndromic hearing loss (ARNSHL). Mutations in transmembrane channel-like gene 1 (TMC1) cause ARNSHL. The p.R34X mutation is the most frequent known mutation in the TMC1 gene. To study the origin of this mutation and determine whether it arose in a common ancestor, we analyzed 21 polymorphic markers spanning the TMC1 gene in 11 unrelated individuals from Algeria, Iran, Iraq, Lebanon, Pakistan, Tunisia, and Turkey who carry this mutation. In nine individuals, we observed significant linkage disequilibrium between p.R34X and five polymorphic markers within a 220 kb interval, suggesting that p.R34X arose from a common founder. We estimated the age of this mutation to be between 1075 and 1900 years, perhaps spreading along the third Hadramaout population movements during the seventh century. A second founder effect was observed in Turkish and Lebanese individuals with markers in a 920 kb interval. Screening for the TMC1 p.R34X mutation is indicated in the genetic evaluation of persons with ARNSHL from North African and Southwest Asia.
Ex Vivo Model of Functional Mitral Regurgitation Using Deer Hearts (2020)

Transcatheter therapies are emerging for functional mitral regurgitation (FMR) treatment, however there is lack of pathological models for their preclinical assessment. We investigated the applicability of deer hearts for this purpose.8 whole deer hearts were housed in a pulsatile flow bench. At baseline, all mitral valves featured normal coaptation. The pathological state was induced by 60-minutes intraventricular constant pressurization. It caused mitral annulus dilation (antero-posterior diameter increase from 31.8 ± 5.6 mm to 39.5 ± 4.9 mm, p = 0.001), leaflets tethering (maximal tenting height increase from 7.3 ± 2.5 mm to 12.7 ± 3.4 mm, p < 0.001) and left ventricular diameter increase (from 67.8 ± 7.5 mm to 79.4 ± 6.5 mm, p = 0.004). These geometrical reconfigurations led to restricted mitral valve leaflets motion and leaflet coaptation loss. Preliminary feasibility assessment of two FMR treatments was performed in the developed model.Deer hearts showed ability to dilate under constant pressurization and have potential to be used for realistic preclinical research of novel FMR therapies. Graphical abstract figure legend: Deer heart mitral valve fiberscopic and echocardiographic images in peak systole at baseline and after inducing the pathological conditions representing functional mitral regurgitation. In the pathological conditions lack of coaptation between the leaflets, enlargement of the antero-posterior distance (red dashed line) and the left ventricular diameter (orange dashed line) were observed.

Design of Electrohydrodynamic Devices with Consideration of Electrostatic Energy (2021)

The importance of actuators that can be integrated with flexible robot structures and mechanisms has increased in recent years with the advance of soft robotics. In particular, electrohydrodynamic (EHD) actuators, which have expandable integrability to adapt to the flexible motion of soft robots, have received much attention in the field of soft robotics. Studies have deepened the understanding of steady states of EHD phenomena but nonsteady states are not well understood. We herein observe the development process of fluid in a microchannel adopting a Schlieren technique with the aid of a high-speed camera. In addition, we analyze the behavior of fluid flow in a microchannel that is designed to have pairs of parallel plate electrodes adopting a computational fluid dynamics technique. Results indicate the importance of considering flow generated by electrostatic energy, which tends to be ignored in constructing and evaluating EHD devices, and by the body force generated by the ion-drag force. By considering these effects, we estimate the development process of EHD flow and confirm the importance of considering the generation of vortices and their interactions inside the microchannel during the development of EHD devices.
129-derived Strains of Mice Are Deficient in DNA Polymerase ι and Have Normal Immunoglobulin Hypermutation (2003)

Recent studies suggest that DNA polymerase eta (poleta) and DNA polymerase iota (poliota) are involved in somatic hypermutation of immunoglobulin variable genes. To test the role of poliota in generating mutations in an animal model, we first characterized the biochemical properties of murine poliota. Like its human counterpart, murine poliota is extremely error-prone when catalyzing synthesis on a variety of DNA templates in vitro. Interestingly, when filling in a 1 base-pair gap, DNA synthesis and subsequent strand displacement was greatest in the presence of both pols iota and eta. Genomic sequence analysis of Poli led to the serendipitous discovery that 129-derived strains of mice have a nonsense codon mutation in exon 2 that abrogates production of poliota. Analysis of hypermutation in variable genes from 129/SvJ (Poli-/-) and C57BL/6J (Poli+/+) mice revealed that the overall frequency and spectrum of mutation were normal in poliota-deficient mice. Thus, either poliota does not participate in hypermutation, or its role is nonessential and can be readily assumed by another low-fidelity polymerase.
Interleukin 13 and its role in gut defence and inflammation (2012)

Interleukin 13 (IL-13) is a cytokine of increasing interest to gastroenterologists because of its developing role in ulcerative colitis, eosinophilic oesophagitis (EO) and fibrosis. Recent data show that IL-13 may play an important role in a novel innate immune response since it can be released by signals from an injured or inflamed epithelium, of particular relevance to the gut. Animal models of IL-13-driven inflammation (from asthma to colitis and EO) are being translated to human disease and providing insight into potential strategies for new therapies. In fact, multiple clinical trials using anti-IL-13 drugs are underway in asthma and are being extended to gastrointestinal diseases. This review presents the current knowledge on IL-13 production and function in the gut, including the cells and receptor signalling pathways involved in mediating IL-13 effects, the proposed mechanisms of IL-13 induced gut disease and the many drugs currently being tested that target IL-13 related pathways.
Downstream Processing of Enzymatically Produced Geranyl Glucoside (2001)

Geraniol plays an important role in the fragrance and flavor industry. The corresponding glucoside has interesting properties as a "slow release" aroma compound. Therefore, the enzymatic production and downstream processing of geranyl glucoside were investigated. Geranyl glucoside was produced in a spray column reactor with an initial production rate of 0.58 mg x U(-1) x h(-1). A pretreated hydrophobic microfiltration membrane was used to prevent migration of the aqueous, enzyme-containing phase to the downstream process. No retention of the glucoside, which accumulated in the geraniol phase, was found. On the basis of examples from the literature, four downstream processes were tested on their viability for this system. Extraction with water and foaming were not suitable to recover geranyl glucoside from geraniol. In the first case, the glucoside selectivity for the geraniol phase was found to be high, which made extraction with water unsuccessful. In the second case it was possible to obtain a stable foam, but significant enrichment of the foam with glucoside did not occur. Adsorption on alumina and distillation under reduced pressure were applied successfully and tested in-line with the bioreactor. A maximum glucoside adsorption of 7.86 mg x g(-1) was achieved on alumina. After desorption and evaporation of the extractant the pure glucoside was obtained quantitatively. A pure product could not be obtained after distillation because a small amount of glucose was present in the permeate as well, which accumulated in the bottom fraction. It was shown that with this reactor system a production of 1 kg of geranyl glucoside in 2 days is possible using an initial amount of 50,000 units of enzyme.
Diaqua[5,10,15,20-tetrakis(4-chlorophenyl)porphyrinato-κ4N]iron(III) trifluoromethanesulfonate–4-hydroxy-3-methoxybenzaldehyde–water (1/1/2) (2014)

In the title compound, [Fe(C44H24Cl4N4)(H2O)2](SO3CF3)·C8H8O3·2H2O, the Fe(III) cation is chelated by the four N atoms of the deprotonated tetra-kis-(4-chloro-tetra-phen-yl)porphyrin (TClPP) and further coordinated by two water mol-ecules in a distorted octa-hedral geometry. In the crystal, the cations, anions, 4-hy-droxy-3-meth-oxy-benzaldehyde and water mol-ecules of crystallization are linked by classical O-H⋯O hydrogen bonds and weak C-H⋯O and C-H⋯Cl hydrogen bonds into a three-dimensional supra-molecular architecture. The crystal packing is further stabilized by weak C-H⋯π inter-actions involving pyrrole and benzene rings. π-π stacking between parallel benzene rings of adjacent 4-hy-droxy-3-meth-oxy-benzaldehyde mol-ecules is also observed, the centroid-centroid distance being 3.8003 (13) Å. The three F atoms of the anion are disordered over two sets of sites, with a refined occupancy ratio 0.527 (12):0.473 (12). The O atom of one water mol-ecule of crystallization is also disordered over two positions in an occupancy ratio of 0.68 (5):0.32 (5).
On the use of J-DSP for on-line laboratories in linear systems courses (2004)

This paper describes the utility of the Java-DSP (J-DSP) technology and the associated on-line laboratories in linear systems courses. J-DSP originally was developed for use in a DSP undergraduate course. Recently the functionality of J-DSP has been extended to support communications, image processing and controls courses. In addition, several new functions have been developed to support advanced DSP applications, such as, speech coding, voice recognition, and spectral estimation. Some of these extensions have also been used to demonstrate the use of DSP in emerging research areas such as Genomics. The first part of the paper discusses these functionality extensions and planned functionality and the second part focuses on the on-line J-DSP laboratories and assessment of J-DSP labs.
