Wearable Sensor-Based Real-Time Sonification of Motion and Foot Pressure in Dance Teaching and Training (2012)

As with tasks involved with motion and gesture, teaching dance can take advantage of auditory displays that map specific dance steps into their acoustic counterparts. Wearable sensors based on acoustic “fingerprints” accompany the dance movements in real-time. This kind of audio feedback has a positive influence on motor movement and perception. For example, joint angles, weight distribution, and energy of jumps are easily recognized through sound. With practice, a student can hear if a complex movement was correctly executed. The auditory system can hear complex patterns of rapid motion, especially aspects of a dance that are not easily seen.
Integrated optic array illuminator: a design for efficient and uniform power distribution (1991)

A design principle for an integrated optic array illuminator is presented, and an array illuminator which can generate uniform beams with 100% power efficiency has been designed. It was found that there exists a trade-off relationship between the beam compression ratio and the maximum number of beams available. Based on this relationship, the possibility and limitation of the proposed scheme are discussed.
Measurement of Terahertz Refractive Index of Metal with Terahertz Time-Domain Spectroscopy (2008)

The complex refractive index of metal has significant effects on plasmon waveguide performance. We measured the complex refractive index of gold in the terahertz frequency range using terahertz time-domain spectroscopy (THz-TDS). The measured refractive index is relatively close to that obtained from Kramers–Kronig analysis of the surface resistance of gold.
Arthroscopic appearance of frozen shoulder (1991)

Patients (n = 150) were referred to a shoulder clinic with a diagnosis of "frozen shoulder" and the suggestion that they be submitted to manipulation. All patients were further investigated using local anesthetic blocks, routine radiography, and, often, computed tomographic scanning and arthrograms. Subsequently, it appeared that only 37 patients qualified for the diagnosis of "primary" frozen shoulder. The others had a "secondary" frozen shoulder from some other painful cause, such as a rotator cuff tear or impingement. The 37 patients were arthroscoped and then manipulated while under general anesthesia. Patients were told that both irrigation and local injection of the joint would have an additional beneficial therapeutic effect in the recovery phase, and they gave prior consent to the procedures. There were no complications. Pain relief was striking. The arthroscopic appearance was uniform: a patchy vascular reaction around the biceps, and the opening into the subscapularis bursa. The capacity of the joint was reduced. In no patient was the infraglenoid recess obliterated, and no adhesions were seen. Such findings at routine shoulder arthroscopy should alert the surgeon to a diagnosis of frozen shoulder if the clinical presentation has been subtle. The findings raise questions about the previous pathological interpretation of this condition.
Diode laser noise at control frequencies in optical videodisc players (1984)

Noise associated with output fluctuation of a diode laser has been observed in the autofocusing and tracking signals of optical videodisc players. This phenomenon has been found to be the result of asymmetric distribution of laser noise on the segmented detectors that derive the control signals. Analysis shows that control frequency noise is caused by the combined effect of interference on the detector and coherency variation in the diode laser due to optical feedback. To reduce this noise, diode lasers in which coherency does not change under optical feedback are desirable.
MECHANISM OF CRYSTALLIZATION FOULING DURING POOL BOILING OF FINNED TUBES (2013)

The formation of deposits on heat transfer surfaces is the main hurdle in optimum operation of thermal desalination units. It is, therefore, common practice to operate these units i.e. MSF under sub-atmospheric pressure to boil saline water below saturation temperature of which depositions occurs. However this comes with high price-tag for excessive use of energy for pumping. Alternative and environmentallyfriendly approach is to modify the surface at such that it could produce lager number of bubbles which cause high scale of turbulence. The present study aims at investigating experimentally the mechanism of crystallization fouling of finned tubes during nucleate pool boiling of CaSO4 solutions. The investigated finned tubes are low finned tube type with fins density of 19 fins per inch, 1.35 fins pitch, and Cu-Ni as substrate. Fouling runs during pool boiling of CaSO4 were carried out at atmospheric pressure for different heat fluxes. A set of video recordings and pictures during clean and fouling runs were also used to interpret the fouling results. Experimental results showed that for the finned tubes: 1) substantial reduction of deposition occurred in comparison to those of stainless steel smooth tubes and 2) if any deposition builds-up on the finned tubes, then it is only a thin layer of crystals which can be easily removed. The superiority of finned tubes to stainless steel smooth tubes is due to the mechanism of bubble formation and detachment from the finned tubes that play a key role in reduction of CaSO4 scale formation on the surface.
Angled tip of the steerable guidewire and its usefulness in percutaneous transluminal coronary angioplasty (1987)

Theoretical analysis and clinical evaluation of single and multi-angled guidewires as an alternative to widely used J-wires suggested that the major determinants of the wire function are the shortest distance between the tip and a long axis of the wire-reaching distance (RD), angulation of the tip, and the length of the angled arm. Their relationship can be characterized by a formula; reaching distance = sin beta X length of the arm. The two clinically most useful multiple angulations--double and triple angles--were evaluated in 54 patients in whom commercial J-wire failed to pass the lesion in 120 s. This value was compared with an average time of 57.90 +/- 3.9 s needed to pass an angled, individually shaped guidewire from the tip of the guiding catheter through the lesion. (P much less than 0.001 or highly significant.) All patients had tortuous vessels, sharply angled branches, and the largest diameter of the stenosed vessel less than 50% of the largest diameter of the left main coronary artery. Thirty-seven lesions were in the obtuse marginal arteries and 17 in the diagonal arteries. The study suggested that angled guidewires shaped according to described guidelines have superior success to commercial, unshaped J-wires in instrumentation of the tortuous vessels with angled branches and markedly varying diameter.
Answering general time sensitive queries (2008)

Time is an important dimension of relevance for a large number of searches, such as over blogs and news archives. So far, research on searching over such collections has largely focused on locating topically similar documents for a query. Unfortunately, topic similarity alone is not always sufficient for document ranking. In this paper, we observe that, for an important class of queries that we call time-sensitive queries, the publication time of the documents in a news archive is important and should be considered in conjunction with the topic similarity to derive the final document ranking. Earlier work has focused on improving retrieval for "recency" queries that target recent documents. We propose a more general framework for handling time-sensitive queries and we automatically identify the important time intervals that are likely to be of interest for a query. Then, we build scoring techniques that seamlessly integrate the temporal aspect into the overall ranking mechanism. We extensively evaluated our techniques using a variety of news article data sets, including TREC data as well as real web data analyzed using the Amazon Mechanical Turk. We examined several alternatives for detecting the important time intervals for a query over a news archive and for incorporating this information in the retrieval process. Our techniques are robust and significantly improve result quality for time-sensitive queries compared to state-of-the-art retrieval techniques.
Aggregation-induced emission in BF<sub>2</sub>–hydrazone (BODIHY) complexes (2011)

A new family of BF2–hydrazone complexes was developed that exhibit enhanced emission in the solid-state. The modularity of the systems enabled their structure–property analysis, which showed that the solid-state fluorescence quantum yield is dependent on the molecule's planarity, dipole moment and number of π–π interactions it forms. One of the BF2–hydrazone complexes was easily transformed into a solid-state acid/base sensor.
High Efficiency of Plating of the Thermophilic Sulfur-Dependent Archaebacterium <i>Sulfolobus acidocaldarius</i> (1989)

A procedure for plating Sulfolobus acidocaldarius using Gelrite as the gelling agent is presented. The technique uses a supporting gel of 0.8% (wt/vol) Gelrite and an overlay soft gel of 0.4% (wt/vol) Gelrite, in which the colonies are grown. The plating efficiency was essentially 100%.
Growth and viability of <i>Streptomyces coelicolor</i> mutant for the cell division gene <i>ftsZ</i> (1994)

A homologue of the bacterial cell division gene ftsZ was cloned from the filamentous bacterium Streptomyces coelicolor. The gene was located on the physical map of the chromosome at about '11 o'clock' (in the vicinity of glkA, hisA and trpB). Surprisingly, a null mutant in which the 399-codon ftsZ open reading frame was largely deleted was viable, even though the mutant was blocked in septum formation. This indicates that cell division may not be essential for the growth and viability of S. coelicolor. The ftsZ mutant was able to produce aerial hyphae but was unable to produce spores, a finding consistent with the idea that ftsZ is required in order for aerial hyphae to undergo septation into the uninucleoid cells that differentiate into spores.
Interplay of strain and intermixing effects on direct-bandgap optical transition in strained Ge-on-Si under thermal annealing (2019)

The influence of thermal annealing on the properties of germanium grown on silicon (Ge-on-Si) has been investigated. Depth dependencies of strain and photoluminescence (PL) were compared for as-grown and annealed Ge-on-Si samples to investigate how intermixing affects the optical properties of Ge-on-Si. The tensile strain on thermally annealed Ge-on-Si increases at the deeper region, while the PL wavelength becomes shorter. This unexpected blue-shift is attributed to Si interdiffusion at the interface, which is confirmed by energy dispersive X-ray spectroscopy and micro-Raman experiments. Not only Γ- and L-valley emissions but also Δ<sub>2</sub>-valley related emission could be found from the PL spectra, showing a possibility of carrier escape from Γ valley. Temperature-dependent PL analysis reveals that the thermal activation energy of Γ-valley emission increases at the proximity of the Ge/Si interface. By comparing the PL peak energies and their activation energies, both SiGe intermixing and shallow defect levels are found to be responsible for the activation energy increase and consequent efficiency reduction at the Ge/Si interface. These results provide an in-depth understanding of the influence of strain and Si intermixing on the direct-bandgap optical transition in thermally annealed Ge-on-Si.
Primary HIV Drug Resistance and Efficacy of First-Line Antiretroviral Therapy Guided by Resistance Testing (2006)

The prevalence of primary drug resistance was 11.2% in chronically HIV-infected patients. HAART guided by resistance testing had similar efficacy in patients with primary drug resistance as compared with patients with wild-type virus. Based on these facts, resistance-adapted first-line HAART is suggested as routine practice.
Biodegradation of Diesel Fuel in Soil Under Various Nitrogen Addition Regimes (2001)

Abstract Bioremediation is a growing technology for treating fuel-contaminated soils. Many biological, physical, and chemical parameters control the rate and efficiency of this process, including type and concentration of contaminants, temperature, oxygen content, and nutrient status. This study investigated the effect that nitrogen sources and concentrations had on the degradation rate of diesel fuel in nutrient limited soil at two carbon-to-nitrogen ratios. The different sources of nitrogen studied were ammonium nitrate, ammonium sulfate, potassium nitrate, urea, and urea oligomers (control release fertilizer). Laboratory experiments were conducted on field-contaminated soil using sealed bioreactors at a controlled temperature of 25°C. For both carbon-to-nitrogen ratios tested, hydrocarbon degradation rates were the highest for the ammonium sulfate (20:1 at 0.032 d−1; 40:1 at 0.019d−1) and urea treatments (20:1 at 0.025 d−1; 40:1 at0.011 d−1). A degradation rate correlation as a function of nitrate and ammonia concentrations was developed. The correlation suggests the occurrence of nitrate inhibition at elevated nitrate concentrations.

Analyzing Functional Brain Images in a Probabilistic Atlas: A Validation of Subvolume Thresholding (2000)

We propose, test, and validate a probabilistic SVT method for mapping statistical variability between groups in subtraction paradigm studies of functional brain data. This method incorporates knowledge of, and controls for, anatomic variability contained in modern human brain probabilistic atlases in functional statistical mapping of the brain.
TEM combined with Al/sub x/Ga/sub 1-x/ as marker layers as a technique for the study of GaAs MBE growth (1985)

It is demonstrated that transmission electron microscopy of cross-section specimens combined with Al/sub x/Ga/sub 1-x/As marker layers can be used to monitor MBE (molecular beam epitaxy) growth of GaAs films. A similar method could be used to study growth morphology of any other film provided that very small mismatch marker layers are available. This technique has potential for quantitative assessment of the surface diffusion during thin film deposition.
Optimization of scintillation performance via a combinatorial multi-element co-doping strategy: Application to NaI:Tl (2015)

A combinatorial approach where doped bulk scintillator materials can be rapidly optimized for their properties through concurrent extrinsic doping/co-doping strategies is presented. The concept that makes use of design of experiment, rapid growth, and evaluation techniques, and multivariable regression analysis, has been successfully applied to the engineering of NaI performance, a historical but mediocre performer in scintillation detection. Using this approach, we identified a three-element doping/co-doping strategy that significantly improves the material performance. The composition was uncovered by simultaneously screening for a beneficial co-dopant ion among the alkaline earth metal family and by optimizing its concentration and that of Tl+ and Eu2+ ions. The composition with the best performance was identified as 0.1% mol Tl+, 0.1% mol Eu2+, and 0.2% mol Ca2+. This formulation shows enhancement of energy resolution and light output at 662 keV, from 6.3 to 4.9%, and from 44 000 to 52 000 ph/MeV, respectively. The method, in addition to improving NaI performance, provides a versatile framework for rapidly unveiling complex and concealed correlations between material composition and performance, and should be broadly applicable to optimization of other material properties.
Di-amidosils with tunable structure, morphology and emission quantum yield: the role of hydrogen bonding (2015)

Di-amidosil hybrids with variable structure, morphology and photoluminescence properties were obtained using different experimental conditions. A correlation between the emission quantum yield value and the degree of order of the amide–amide hydrogen-bonded array was established for mono- and di-amidosils.
Mechanisms of resistance to anti-EGFR monoclonal antibody treatment in metastatic colorectal cancer (2010)

Metastatic colorectal cancer (mCRC) continues to be counted as a major health problem. The introduction of newer cytotoxics, irinotecan and oxaliplatin, has achieved a significant improvement in survival rates. Novel targeted therapies (bevacizumab, and cetuximab) in combination with most efficient chemotherapy regimens have pushed the median survival beyond the 2-year mark and increased the proportion of patients which could benefit from resection of metastatic lesions. In addition, several studies have proved that the CRC mutation profiles should influence patient selection or stratification in prospective trials. KRAS mutational status represents a paradigm for biomarker development in the era of molecular targeted therapies. The present article is an overview of the most important studies in the development of biomarkers for the optimization of anti-epidermal growth factor receptor (anti-EGFR) treatment in mCRC, beyond KRAS mutations, which is a work in progress. The aim will be to identify molecular markers that might be used to select patients with a higher probability of response to anti-EGFR monoclonal antibodies. Overall the accumulating evidence of the molecular biology of CRC has substantially changed the approach to mCRC treatment and has given clinicians more rational options for treating this illness.
Small Cells for 5G Mobile Networks (2015)

The evolution of wireless communication systems is now characterised by the tremendous growth of mobile data traffic and the number of connected devices. In response to the unprecedented levels of demand, cellular networks are undergoing a major shift in their deployment and optimisation. New infrastructure elements, such as femto/pico base stations, fixed/mobile relays, cognitive radios, and distributed antennas are being massively deployed, paving the way for the next generation of cellular systems and networks, which will be more efficient in terms of spectrum use, multi-RAT support and energy efficiency, and will use high-order multi-RAT support techniques together with massive deployments of small cells for higher re-use. As a consequence, new 5G cellular deployments could be characterised by a more unplanned, irregular and random location of access nodes, whose positions may vary widely over a very large area. As a result, the interference scenarios will be more complex, thus making evaluation and design of different enabling communication technologies and protocols more challenging. In this emerging Heterogeneous Networking environment, small cells will play a fundamental role towards the successful deployment of 5th Generation systems. In this chapter, we provide an overview of the key drivers for small-cell deployment, and show how densification through advanced MIMO technology and small cells can complement each other to satisfy the projected traffic demand. However, since forecasts of mobile data traffic seem to be continuously on the rise, it will become necessary to move into the mmWave bands where sufficiently large swathes of spectrum are available.
Revealing a Role of MicroRNAs in the Regulation of the Biological Clock (2007)

In the last decade numerous studies have unveiled the pervasive role of microRNAs (miRNAs), a class of small, non-coding transcripts, in post-transcriptional gene regulation in biological processes ranging from development to cancer. Until recently, the circadian clock has been modeled as simple, interlocking, transcriptional feedback loops that drive rhythmic gene expression of a few core 'clock' determinants. The biological implications of miRNAs are extended further by our recent discovery that miRNAs are expressed in the suprachiasmatic nuclei (SCN), the master circadian clock in mammals, in a rhythmic and inducible fashion, and modulate the intrinsic pacemaker activity and resetting capacity of the SCN. In this review, we will discuss the specific roles of miRNA-(miR-)132 and miR-219 in the SCN, as well as a more general outlook on this newly elucidated layer of circadian clock regulation: inducible translation control via miRNAs.
Review of high‐dose intravenous vitamin<scp>C</scp>as an anticancer agent (2014)

In the 1970s, Pauling and Cameron reported increased survival of patients with advanced cancer treated with high-dose intravenous (IV) vitamin C (L-ascorbate, ascorbic acid). These studies were criticized for their retrospective nature and lack of standardization of key prognostic factors including performance status. Subsequently, several well-designed randomized controlled trials failed to demonstrate a significant survival benefit, although these trials used high-dose oral vitamin C. Marked differences are now recognized in the pharmacokinetics of vitamin C with oral and IV administration, opening the issue of therapeutic efficacy to question. In vitro evidence suggests that vitamin C functions at low concentrations as an antioxidant but may have pro-oxidant activity at high concentrations. The mechanism of its pro-oxidant action is not fully understood, and both intra- and extracellular mechanisms that generate hydrogen peroxide have been proposed. It remains to be proven whether vitamin C-induced reactive oxygen species occur in vivo and, if so, whether this will translate to a clinical benefit. Current clinical evidence for a therapeutic effect of high-dose IV vitamin C is ambiguous, being based on case series. The interpretation and validation of these studies is hindered by limited correlation of plasma vitamin C concentrations with response. The methodology exists to determine if there is a role for high-dose IV vitamin C in the treatment of cancer, but the limited understanding of its pharmacodynamic properties makes this challenging. Currently, the use of high-dose IV vitamin C cannot be recommended outside of a clinical trial.

New pyridine dithiols: synthesis and structures of complexes with acids (1997)

Pyridine dithiols have been synthesized by base-induced addition of 2,6-lutidine to (non-enolisable) thioketones, and have been found to encapsulate various acids.
