Ultrasonic Attenuation in Zinc Single Crystals at Low Temperatures (1969)

The ultrasonic attenuation in zinc single crystals were studied in the temperature range from 4.2° K to 300° K. In pure zinc specimen, three peaks were observed in the attenuation, temperature curves. The peaks were named P 1 , P 2 and P 3 in the order from lower to higher temperature. P 1 , P 2 and P 3 were observed in the attenuation of the longitudinal wave along the direction 43.25° to c-axis and the shear wave parallel to the basal plane. On the other hand, only P 3 was observed in the attenuation of the longitudinal waves travelling perpendicular to the basal plane. The relaxation processes appearing in the form of P 1 , P 2 and P 3 peaks were interpreted to be associated with the dislocation movement in the basal plane, prismatic plane and pyramidal plane, respectively. A theory of relaxation process in terms of formation of a pair of kinks is proposed.

Study of asymmetric traffic influence on ieee 802.11 WLAN family, enhancement proposals (2004)

This paper is focused on the study of WLAN performance in IEEE 802.11 networks that are in a situation of asymmetric traffic, where the access point (AP) transmits much more than the user stations (US). This situation is very different from the symmetric one, wherein all the stations have the same traffic load. The paper also presents a discussion of the different mechanisms in order to increase AP priority under the asymmetric traffic situation.
Making your views known: the importance of anonymity before and after classroom debates (2008)

The current study aimed to examine the effect of anonymity and privacy on students' voting behaviour before and after classroom debate. A positioning system with three different settings was prototyped (Private, Anonymous or Public). It was predicted that students voting publicly would be less inclined to express changes in their views, and that they would tend to conform to the class' overall position more than students voting either anonymously or privately. Three groups of students (N=55) taking A Level General Studies took part in debates and voted in one of the three conditions. Results supported both hypotheses and suggest that anonymity and privacy play a crucial role in encouraging students to express individual and authentic positions. The implications of these results for technology mediated voting systems are discussed.

Weight concerns and change in smoking behavior over two years in a working population. (1995)

The hypothesis that weight concerns are related to less successful smoking cessation and greater relapse among ex-smokers was prospectively evaluated. A population-based sample of 4981 working women and men 17 to 71 years of age was surveyed at 32 work sites. Current and previous weight loss efforts and smoking behavior were self-reported at baseline and 2 years later. Dieting and weight concerns were unrelated to smoking cessation or relapse. However, female smokers who had previously participated in a formal weight control program were three times more likely to quit smoking than those without a history of participation (25% vs 11%; odds ratio = 3.25, 95% confidence interval = 1.86, 5.67). Weight concerns and dieting efforts do not appear to inhibit smoking cessation or increase relapse in adults.
Air-Water Mass Transfer (1991)

This monograph, Air-Water Mass Transfer: Selected Papers from the Second International Symposium on Gas Transfer at Water Surfaces, consists of papers presented at the Symposium which was held in Minneapolis, Minnesota, September 11-14, 1990. The topics discussed in these papers include: 1) Fundamentals of physical phenomenon and modeling, 2) laboratory and field measurement techniques, and 3) applications of air-water mass transfer technology. The text begins with a discussion of some of the physical characteristics of and chemical effects on gas transfer. Next, comes an exploration of physical phenomena such as turbulence, wind, waves, convection, density stratification, and bubbles including the development of numerical, conceptual, semi-empirical, and empirical models. This is followed by 13 papers concerning different laboratory and field measurement techniques such as remote sensing and gas tracer techniques. Finally, the majority of the papers discuss various applications of gas transfer to streams and rivers, lakes and reservoirs, hydraulic structures, water and wastewater treatment, seas and oceans, and artificial aeration.
Proceedings of the 3rd International on Workshop on Physical Analytics (2016)

Welcome to the 3rd International Workshop on Physical Analytics (WPA) being held in Singapore on June 26, 2016. We are honored to serve as the chairs for this latest WPA edition that continues in the tradition of previous workshops in the series that were also co-located with MobiSys.

Broadly speaking, WPA is motivated by the observations that people spend a significant part of their daily lives performing a variety of activities in the physical world---travelling to places (including commuting to/from work using public or private transport), dwelling and engaging in various activities at various locations (e.g., exercising in the gym, eating at restaurants and food courts), interacting with various physical objects and artefacts (e.g., touching or picking up products at a retail store, or browsing through books and magazines at a library), being subject to various audiovisual stimuli (e.g., listening to announcements at transit hubs, watching advertisements on public displays or movies on TV) and interacting with other people (in groups, as part of crowds or one-on-one). These activities and interactions contain a wealth of information about user behavior, preferences, attitudes and interests, that, if harnessed, can benefit both users and consumer-facing businesses. While research has been underway in utilizing various sensing and analytics tools to capture and annotate such behavior (e.g., profile smoking episodes using wearable devices or monitor consumer reactions to advertising content via video analysis), the vast majority of such research focuses on exploring individual sensing techniques targeted at specific activities, and is scattered across various academic forums. The goal of this workshop series is to offer a unified forum to explore both (a) the technologies (current and emerging) that can enable unobtrusive capture of such individual and collective physical world behavior, and (b) the realworld commercial applications and services that leverage upon such understanding of physical world behavior. By bringing together researchers and practitioners from industry to have a continuing conversation on Physical Analytics, our goal is to help coalesce a research agenda for our community.

This year we are particularly honored to have Kyle Jamieson (Princeton University) giving the workshop keynote. We look forward to hearing Kyle's perspective on what new innovations in high-precision localization, and breakthroughs in wireless networking more generally, will mean for the physical analytics area.

Coherent Optical Pattern Recognition: A Review (1985)

Recent progress in coherent optical pattern recognition is reviewed. Emphasis is given to techniques for multiclass distortion-invariant pattern recognition. Real-time and practical architectures and algorithms are described, and recent results on extensive data bases are noted. Feature-extraction and correlation architectures are chosen as the two major approaches. The feature-extraction techniques considered include Fourier coefficients, chord distributions, and moments. The correlator approaches emphasize the use of synthetic discriminant functions to achieve multiclass distortion-invariant pattern recognition.

A Modified Shuffled Frog Leaping Algorithm for PAPR Reduction in OFDM Systems (2015)

Significant reduction of the peak-to-average power ratio (PAPR) is an implementation challenge in orthogonal frequency division multiplexing (OFDM) systems. One way to reduce PAPR is to apply a set of selected partial transmission sequence (PTS) to the transmit signals. However, PTS selection is a highly complex NP-hard problem and the computational complexity is very high when a large number of subcarriers are used in the OFDM system. In this paper, we propose a new heuristic PTS selection method, the modified chaos clonal shuffled frog leaping algorithm (MCCSFLA). MCCSFLA is inspired by natural clonal selection of a frog colony, it is based on the chaos theory. We also analyze MCCSFLA using the Markov chain theory and prove that the algorithm can converge to the global optimum. Simulation results show that the proposed algorithm achieves better PAPR reduction than using others genetic, quantum evolutionary and selective mapping algorithms. Furthermore, the proposed algorithm converges faster than the genetic and quantum evolutionary algorithms.
DC–DC High Step-up Converter with Low Count of Switches Based on Resonant Switched-Capacitor Topology (2019)

This paper presents the research results of a novel DC-DC boost converter with high voltage gain, low count of switches and low voltage stresses on the switches. The operation of the converter is based on the principle of a switched-capacitor voltage multiplier (SCVM) but the utilization of the components is very effective in the proposed idea, because the converter is able to charge two output capacitors with only one additional switch and a diode. An important benefit of the proposed converter is that the gate circuits do not require isolated supply and all the switches utilize bootstrap supply. The converter can be designed with air-based or planar PCB-type chokes. Therefore, it can achieve low weight, low volume, decreased cost and simplified assembling. The voltage stress on two switches is close to only half of the output voltage. The stresses on the other switches are much lower, which is very favorable. The converter can be designed in various switch technologies. In a design without ferrite cores and with WBG switches, the converter can operate at higher temperatures.
Genomic footprints of activated telomere maintenance mechanisms in cancer (2020)

Cancers require telomere maintenance mechanisms for unlimited replicative potential. They achieve this through TERT activation or alternative telomere lengthening associated with ATRX or DAXX loss. Here, as part of the ICGC/TCGA Pan-Cancer Analysis of Whole Genomes (PCAWG) Consortium, we dissect whole-genome sequencing data of over 2500 matched tumor-control samples from 36 different tumor types aggregated within the ICGC/TCGA Pan-Cancer Analysis of Whole Genomes (PCAWG) Consortium to characterize the genomic footprints of these mechanisms. While the telomere content of tumors with ATRX or DAXX mutations (ATRX/DAXX<sup>trunc</sup>) is increased, tumors with TERT modifications show a moderate decrease of telomere content. One quarter of all tumor samples contain somatic integrations of telomeric sequences into non-telomeric DNA. This fraction is increased to 80% prevalence in ATRX/DAXX<sup>trunc</sup> tumors, which carry an aberrant telomere variant repeat (TVR) distribution as another genomic marker. The latter feature includes enrichment or depletion of the previously undescribed singleton TVRs TTCGGG and TTTGGG, respectively. Our systematic analysis provides new insight into the recurrent genomic alterations associated with telomere maintenance mechanisms in cancer.
The effect of pulsed electromagnetic field exposure on osteoinduction of human mesenchymal stem cells cultured on nano-TiO2 surfaces (2018)

Human bone marrow-derived mesenchymal stem cells (hBM-MSCs) are considered a great promise in the repair and regeneration of bone. Considerable efforts have been oriented towards uncovering the best strategy to promote stem cells osteogenic differentiation. In previous studies, hBM-MSCs exposed to physical stimuli such as pulsed electromagnetic fields (PEMFs) or directly seeded on nanostructured titanium surfaces (TiO2) were shown to improve their differentiation to osteoblasts in osteogenic condition. In the present study, the effect of a daily PEMF-exposure on osteogenic differentiation of hBM-MSCs seeded onto nanostructured TiO2 (with clusters under 100 nm of dimension) was investigated. TiO2-seeded cells were exposed to PEMF (magnetic field intensity: 2 mT; intensity of induced electric field: 5 mV; frequency: 75 Hz) and examined in terms of cell physiology modifications and osteogenic differentiation. Results showed that PEMF exposure affected TiO2-seeded cells osteogenesis by interfering with selective calcium-related osteogenic pathways, and greatly enhanced hBM-MSCs osteogenic features such as the expression of early/late osteogenic genes and protein production (e.g., ALP, COL-I, osteocalcin and osteopontin) and ALP activity. Finally, PEMF-treated cells resulted to secrete into conditioned media higher amounts of BMP-2, DCN and COL-I than untreated cell cultures. These findings confirm once more the osteoinductive potential of PEMF, suggesting that its combination with TiO2 nanostructured surface might be a great option in bone tissue engineering applications.
A splicing mutation accounts for the lack of p53 gene expression in a CML blast crisis cell line: a novel mechanism of p53 gene inactivation (1990)

Alterations of the p53 anti-oncogene have recently been found to occur frequently in the blast crisis of chronic myelocytic leukaemia. The p53 gene may be altered by gross structural alterations or by point mutations in the coding sequence. We now report a novel mechanism of gene inactivation in a blast crisis cell line where a mutation in a splice donor site at the 5' end of the fifth intron of the gene interrupts RNA processing and gene expression.
Bilateral corneal ulceration in ocular graft-versus-host disease (2013)

Frequent follow-up and bilateral monitoring are highly recommended in cases of ocular GVHD-associated stromal thinning, as bilateral involvement or rapid progression to corneal perforation can occur.
Modeled Arctic ozone depletion in winter 1997/1998 and comparison with previous winters (2000)

We have used a three‐dimensional stratospheric model to investigate Arctic ozone depletion in the three winters from 1995/1996 to 1997/1998, winters with quite different dynamical conditions. We have diagnosed the chemical depletion from the model and compared the model ozone with ground‐based and sonde measurements. In winter 1997/1998 the lower stratosphere was generally much warmer than the previous two cold winters. However, the occurrence of low temperatures in December 1997 did cause chlorine activation and ozone loss in the model. In fact, despite the very different meteorological conditions for these three winters, by mid‐February the model‐calculated mean vortex loss was similar in each year at around 20% at 480 K. Larger differences in the calculated loss occurred when low temperatures persisted into March; this seems a prerequisite for very large loss. By late March the model‐calculated mean vortex column loss was 53 Dobson units (DU) in 1998, 71 DU in 1996, and 80 DU in 1997. A first effort at a detailed day‐to‐day validation of a chemical transport model by comparison with ozone measurements is presented. The model reproduces the mean column observations to within about ±10%, although the bias varies in magnitude and changes sign in different years. The agreement between the model and ozonesonde profiles in the lower stratosphere varies from year to year and during the course of a particular winter/spring. In winter 1997/1998, the model agrees well with sonde profiles at the 480 K and 555 K levels with a positive mean difference (ozonesonde values minus model values) with amplitude of less than 6%. In contrast, in winter 1996/1997, the mean difference is negative and the amplitude is less than 15%. In winter 1995/1996 the mean difference is negative and the amplitude reaches 43%. The differences in 1995/1996 and 1996/1997 result despite good agreement between model and observations in midwinter, and they develop following the large chemical losses which occurred in those winters. We suggest that a major contribution to the model/observation differences for those two winters is a model underestimation of the chemical ozone loss.
Enhanced CD8 T Cell Responses through GITR-Mediated Costimulation Resolve Chronic Viral Infection (2015)

Chronic infections are characterized by the inability to eliminate the persisting pathogen and often associated with functional impairment of virus-specific T-cell responses. Costimulation through Glucocorticoid-induced TNFR-related protein (GITR) can increase survival and function of effector T cells. Here, we report that constitutive expression of GITR-ligand (GITRL) confers protection against chronic lymphocytic choriomeningitis virus (LCMV) infection, accelerating recovery without increasing pathology. Rapid viral clearance in GITRL transgenic mice coincided with increased numbers of poly-functional, virus-specific effector CD8+ T cells that expressed more T-bet and reduced levels of the rheostat marker PD-1. GITR triggering also boosted the helper function of virus-specific CD4 T cells already early in the infection, as was evidenced by increased IL-2 and IFNγ production, and more expression of CD40L and T-bet. Importantly, CD4-depletion experiments revealed that the expanded pool of virus-specific effector CD8 T cells and the ensuing viral clearance in LCMV-infected GITRL tg mice was entirely dependent on CD4 T cells. We found no major differences for NK cell and regulatory T cell responses, whereas the humoral response to the virus was increased in GITRL tg mice, but only in the late phase of the infection when the virus was almost eradicated. Based on these findings, we conclude that enhanced GITR-triggering mediates its protective, anti-viral effect on the CD8 T cell compartment by boosting CD4 T cell help. As such, increasing costimulation through GITR may be an attractive strategy to increase anti-viral CTL responses without exacerbating pathology, in particular to persistent viruses such as HIV and HCV.
Attaining the quantum limit of passive imaging (2016)

We consider the problem, where a camera is tasked with determining one of two hypotheses: first with an incoherently-radiating quasi-monochromatic point source and the second with two identical closely spaced point sources. We are given that the total number of photons collected over an integration time is assumed to be the same under either hypothesis. For the one-source hypothesis, the source is taken to be on-axis along the line of sight and for the two-source hypothesis, we give ourselves the prior knowledge of the angular separation of the sources, and they are assumed to be identical and located symmetrically off-axis. This problem was studied by Helstrom in 1973, who evaluated the probability of error achievable using a sub-optimal optical measurement, with an unspecified structured realization. In this paper, we evaluate the quantum Chernoff bound, a lower bound on the minimum probability of error achievable by any physically-realizable receiver, which is exponentially tight in the regime that the integration time is high. We give an explicit structured receiver that separates three orthogonal spatial modes of the aperture field followed by quantum-noise-limited time-resolved photon measurement and show that this achieves the quantum Chernoff bound. In other words, the classical Chernoff bound of our mode-resolved detector exactly matches the quantum Chernoff bound for this problem. Finally, we evaluate the classical Chernoff bound on the error probability achievable using an ideal focal plane array---a signal shot-noise limited continuum photon-detection receiver with infinitely many infinitesimally-tiny pixels---and quantify its performance gap with the quantum limit.

Best Inhibitory Frequencies of Complex Units in the Eighth Nerve of the Bullfrog (1968)

Complex units in the bullfrog have Best Excitatory Frequencies (BEF) below 900 Hz, and can be inhibited by tones in a broad frequency range. A unit's Best Inhibitory Frequency (BIF) is always greater than its best excitatory frequency. A scatter diagram of BIF vs BEF for 38 units indicates that mean BIF increases as BEF increases.
3D PRINTING OF ANISOTROPIC METAMATERIALS (2012)

Material properties in radio frequency and microwave regimes are limited due to the lack of molecular resonances at these frequencies. Metamaterials are an attractive means to realize a prescribed permittivity or permeability function, but these are often prohibitively lossy due to the use of ine-cient metallic resonators. All-dielectric metamaterials ofier excellent potential to overcome these losses, but they provide a much weaker interaction with an applied wave. Much design freedom can be realized from all-dielectric structures if their dispersion and anisotropy are cleverly engineered. This, however, leads to structures with very complex geometries that cannot be manufactured by conventional techniques. In this work, artiflcially anisotropic metamaterials are designed and then manufactured by 3D printing. The efiective material properties are measured in the lab and agree well with model predictions.
Detection Of Cross‐Hybridized DNA Strands within Pools Using SYBR Green I Fluorescence (2007)

The ability to quickly identify cross‐hybridized DNA duplexes is important the design of DNA libraries for use of microarrays, mutation analysis, DNA computing, and combinatorial group testing. These applications rely on hybridization of perfect Watson‐Crick complements to ensure predictable results. We designed a method suitable for detecting cross‐hybridizations in pools of up to 36 different non‐hybridizing strands using the fluorescent dye SYBR Green I. Test strands of length 16 bp were designed to test a variety of bulges and dangling ends. Some of these test strands formed duplexes that were detected in a pool with 35 other non‐hybridizing strands. Testing in pools allows the verification of multiple strands at once, leading to faster confirmation of DNA libraries. We are applying these methods to the classical group testing theory which allows us to test randomly constructed pools and identify the specific mispaired strands.
