Peltier effect in doped silicon microchannel plates (2011)

The Seebeck coefficient is determined from silicon microchannel plates (Si MCPs) prepared by photo-assisted electrochemical etching at room temperature (25 °C). The coefficient of the sample with a pore size of 5 × 5 μm2, spacing of 1 μm and thickness of about 150 μm is −852 μV/K along the edge of the square pore. After doping with boron and phosphorus, the Seebeck coefficient diminishes to 256 μV/K and −117 μV/K along the edge of the square pore, whereas the electrical resistivity values are 7.5 × 10−3 Ω·cm and 1.9 × 10−3 Ω·cm, respectively. Our data imply that the Seebeck coefficient of the Si MCPs is related to the electrical resistivity and is consistent with that of bulk silicon. Based on the boron and phosphorus doped samples, a simple device is fabricated to connect the two type Si MCPs to evaluate the Peltier effect. When a proper current passes through the device, the Peltier effect is evidently observed. Based on the experimental data and the theoretical calculation, the estimated intrinsic figure of merit ZT of the unicouple device and thermal conductivity of the Si MCPs are 0.007 and 50 W/(m·K), respectively.

Low power cryptography (2005)

Today more and more sensitive data is stored digitally. Bank accounts, medical records and personal emails are some categories that data must keep secure. The science of cryptography tries to encounter the lack of security. Data confidentiality, authentication, non-reputation and data integrity are some of the main parts of cryptography. The evolution of cryptography drove in very complex cryptographic models which they could not be implemented before some years. The use of systems with increasing complexity, which usually are more secure, has as result low throughput rate and more energy consumption. However the evolution of cipher has no practical impact, if it has only theoretical background. Every encryption algorithm should exploit as much as possible the conditions of the specific system without omitting the physical, area and timing limitations. This fact requires new ways in design architectures for secure and reliable crypto systems. A main issue in the design of crypto systems is the reduction of power consumption, especially for portable systems as smart cards.
Long-term feeding of Atlantic salmon in seawater with low dietary long-chain n-3 fatty acids affects tissue status of the brain, retina and erythrocytes (2016)

In two long-term feeding trials in seawater, Atlantic salmon were fed EPA+DHA in graded levels, from 1·3 to 7·4 % of fatty acids (FA, 4-24 g/kg feed) combined with approximately 10 % 18 : 3n-3, at 6 and 12°C. Dietary EPA appeared to be sufficient in all diet groups, as no differences were seen in polar lipid tissue concentrations of either the brain, retina or erythrocytes. For DHA, a reduction in tissue levels was observed with low dietary supply. Effects on brain DHA at ≤1·4 % EPA+DHA of dietary FA and retina DHA at ≤2·7 % EPA+DHA of dietary FA were only observed in fish reared at 6°C, suggesting an effect of temperature, whereas tissue levels of n-6 FA increased as a response to increased dietary n-6 FA in both the brain and the retina at both temperatures. DHA levels in erythrocytes were affected by ≤2·7 % EPA+DHA at both temperatures. Therefore, DHA appears to be the limiting n-3 FA in diets where EPA and DHA are present in the ratios found in fishmeal and fish oil. To assess the physiological significance of FA differences in erythrocytes, the osmotic resistance was tested, but it did not vary between dietary groups. In conclusion, ≤2·7 % EPA+DHA of FA (≤9 g/kg feed) is not sufficient to maintain tissue DHA status in important tissues of Atlantic salmon throughout the seawater production cycle despite the presence of dietary 18 : 3n-3, and effects may be more severe at low water temperatures.
Evaluation of automatic classroom capture for computer science education (2010)

Our research into automatic recording of the complete classroom experience has led to the development of many software systems, one of which captures an image stream of all content presented on a computer. We have just completed a first deployment of this computer capture system in which 3 separate courses were recorded for an entire semester with the content being presented to students within 24 hours of the class meeting time. This system has been envisioned as a component of a complete lecture capture system but a component with real value even when used as a stand alone. In this paper we discuss student feedback to this computer capture system, revision of system functionality, and thoughts on the usefulness of capturing computer content in computer science courses in general.

Elusive π-helical peptide foldamers spotted by chiroptical studies (2019)

A series of oligomers containing alternate l-Ala and pGlu (pyroglutamic acid) both in the L and D form have been prepared and conformationally investigated by X-ray, NMR, UV/ECD, IR/VCD and molecular modelling. X-ray diffraction analysis was possible for the shortest oligomers LL-1 and LD-1. Molecular dynamics simulations of the oligomers demonstrated that the energy landscapes of the LL-series are broad. In contrast, the energy landscapes of the LD-series are characterized by well-defined minima corresponding to specific conformational structures. A single well-defined minimum exists in the energy landscape of the largest oligomer LD-8, corresponding to a precise conformation, characterized by i + 5 →i N-HO[double bond, length as m-dash]C hydrogen bonds, typical of a π-helix. ECD and VCD spectra were measured to identify the chiroptical profiles of the oligomers. The most striking element in the ECD spectra of the LD-series is their exceptionally strong intensity, which confirms that these polypeptides attain a high degree of helical order. VCD spectra for the LD-series are well reproduced by frequency calculations when π-helix folds are employed as input structures, suggesting that a symmetrical VCD couplet around 1720 cm<sup>-1</sup> can be taken as the VCD signature of π-helices.
Systematic Investigation of Porogen Size and Content on Scaffold Morphometric Parameters and Properties (2007)

A systematic investigation of tissue engineering scaffolds prepared by salt leaching of a photopolymerized dimethacrylate was performed to determine how the scaffold structure (porosity, pore size, etc.) can be controlled and also to determine how the scaffold structure and the mechanical properties are related. Two series of scaffolds were prepared with (1) the same polymer-to-salt ratio but different salt sizes (ranging from average size of 100 to 390 microm) and (2) the same salt size but different polymer-to-salt ratios (ranging from salt mass of 70 to 90%). These scaffolds were examined to determine how the fabrication parameters affected the scaffold morphometric parameters and corresponding mechanical properties. Combined techniques of X-ray microcomputed tomography (microCT), mercury porosimetry, and gravimetric analysis were used to determine the scaffold parameters, such as porosity, pore size, and strut thickness and their size distributions, and pore interconnectivity. Scaffolds with porosities ranging from 57% to 92% (by volume) with interconnected structures could be fabricated using the current technique. The porosity and strut thickness were subsequently related to the mechanical response of the scaffolds, both of which contribute to the compression modulus of the scaffold. The current study shows that the structure and properties of the scaffold could be tailored by the size and the amount of porogen used in the fabrication of the scaffold.
Data-centric storage in Sensornets (2002)

Sensornets are large-scale distributed sensing networks comprised of many small sensing devices equipped with memory, processors, and short-range wireless communication. Making effective use of sensornet data will require scalable, self-organizing, and energy-efficient data dissemination algorithms. Recent work has identified data-centric routing as one such method. In this paper we suggest that a companion method, data-centric storage, may also be a useful approach.
Transmembrane channel-like ( tmc ) gene regulates Drosophila larval locomotion (2016)

Drosophila larval locomotion, which entails rhythmic body contractions, is controlled by sensory feedback from proprioceptors. The molecular mechanisms mediating this feedback are little understood. By using genetic knock-in and immunostaining, we found that the Drosophila melanogaster transmembrane channel-like (tmc) gene is expressed in the larval class I and class II dendritic arborization (da) neurons and bipolar dendrite (bd) neurons, both of which are known to provide sensory feedback for larval locomotion. Larvae with knockdown or loss of tmc function displayed reduced crawling speeds, increased head cast frequencies, and enhanced backward locomotion. Expressing Drosophila TMC or mammalian TMC1 and/or TMC2 in the tmc-positive neurons rescued these mutant phenotypes. Bending of the larval body activated the tmc-positive neurons, and in tmc mutants this bending response was impaired. This implicates TMC's roles in Drosophila proprioception and the sensory control of larval locomotion. It also provides evidence for a functional conservation between Drosophila and mammalian TMCs.
Indices of Windchill of Clothed Persons (1971)

The concept of windchill as a measure of the combined effects of low temperature and wind is reviewed. An analysis is presented of the effect of these variables on a person dressed for cold climates and takes account of all important modes of heat loss, including breathing and heat transfer through clothing. This analysis leads to two chief indices of windchill: the windchill equivalent temperature, which is tabulated and compared with existing tables, and the clothing thickness required to maintain a person in thermal equilibrium. The distributions of clothing thickness and of the windchill of exposed skin at 30C are described.

Text-Dependent Speaker Recognition System for Indian Languages (2007)

Summary Speaker Recognition is a process of automatically recognising who is speaking on the basis of speaker dependent features of the speech signal. Although speaker recognition is currently not as robust as other biometrics such as finger prints and retinal scans, speech holds great promise. Speech based recognition permits remote access. Speech is very important in a country like India with a large population with low levels of literacy and education. Speech empowers people by helping them to overcome the barriers of language and complexity of usage. In this paper we describe a system for speaker recognition designed with low security access control systems in mind. An isolated word speech recognition system is used to recognize the spoken password and then a speaker identification system is used to further confirm the identity of the user amongst a given set of users. Mel Frequency Cepstral Coefficients have been used to build Hidden Markov Models. The HTK tool kit has been used to build these systems. Mahalanobis distance measure is employed. Experiments conducted are described and the results are shown. Mostly spoken ten Indian languages speech data has been used in these experiments. It can be seen that the system gives very good performance for the intended task.
A comparative study of local feature extraction algorithms for Web pornographic image recognition (2015)

Feature extraction algorithm plays an important part in content based pornographic image recognition. In this paper, the performances of six outstanding local feature extraction algorithms are compared and analysed in Web pornographic image recognition. The six algorithms include Scale Invariant Feature Transform, Speeded Up Robust Features, Oriented FAST and Rotated BRIEF, Fast Retina Keypoint, Binary Robust Invariant Scalable Keypoints and KAZE. Through the comparison experiments based on the same image recognition scheme, we conclude that the highest recognition precision can be obtained by SURF, and a good trade-off between recognition speed and precision can be achieved by ORB.
Performance Evaluation of Contract Net-Based Heterarchical Scheduling for Flexible Manufacturing Systems (1997)

ABSTRACT This article presents a heterarchical scheduling approach for flexible manufacturing systems. The approach adopts a multiagent cooperative problem solving paradigm by using a bidding mechanism based on the contract net protocol to generate the production plan and schedule. Overall, scheduling is implemented using a Production Reservation approach. A typical job shop testbed demonstrates the effectiveness of this approach by comparing its performance to heuristic dispatching rules. Production Reservation augmented with the heuristic dispatching rules has also been shown to be even more effective, and should prove especially valuable in large variety discrete part and assembly manufacturing processes.
Effect of human urinary macrophage colony-stimulating factor on the immune functions and the blood cell counts in patients with ovarian carcinoma receiving cytotoxic chemotherapy (2001)

The present study investigated the effect of macrophage colony-stimulating factor (M-CSF) on the immune functions and blood cell counts of patients with ovarian carcinoma receiving cytotoxic chemotherapy (CTX). Seventy-five consecutive patients with white blood cell counts less than 3,000/microl after CTX were randomly assigned to receive either M-CSF (human urinary macrophage colony-stimulating factor: hM-CSF, 8x106 U as 7-day intravenous infusions) or no treatment. Immune assays in addition to routine peripheral blood examinations were performed on these patients at various time points. hM-CSF dosing significantly increased monocyte, lymphocyte, granulocyte, and platelet counts that were decreased by CTX. hM-CSF also significantly enhanced lymphokine-activated killer and natural killer activities, which was accompanied by a significantly augmented interleukin (IL)-2 production. Interestingly, IL-2 production was enhanced by hM-CSF dosing in 24 of the 27 patients with a pre-hM-CSF level of IL-2 below 10 U/ml, but such an effect was not observed in nine of the 10 patients having a basal value of 10 U/ml or higher. Thus, hM-CSF is considered to be a cytokine that can augment or regulate immune functions impaired by CTX and increase blood cell counts that are decreased by CTX.
The mechanical design of a kinematic mount for the Mid Infrared Instrument Focal Plane Module on the James Webb Space Telescope (2009)

The detector assembly for the Mid Infrared Instrument (MIRI) of the James Webb Space Telescope (JWST) is mechanically supported in the focal plane module (FPM) assembly with an efficient hexapod design. The kinematic mount design allows for precision adjustment of the detector boresight to assembly alignment fiducials and maintains optical alignment requirements during flight conditions of launch and cryogenic operations below 7 Kelvin. This kinematic mounting technique is able to be implemented in a variety of optical-mechanical designs and is capable of micron level adjustment control and stability over wide dynamic and temperature ranges.
Heck functionalization of an asymmetric aza-BODIPY core: synthesis of far-red infrared probes for bioimaging applications (2016)

As part of our ongoing work on the synthesis of a new class of plant hormones named Strigolactones (SLs) and their analogues, we became interested in tracing bioactive molecules with red emitting BODIPY fluorophores in order to unravel signaling and distribution of SLs in plants. In this paper we report on an unprecedented Heck functionalization of azadipyrromethenes (aza-DIPY) which allows for the introduction of suitable functional groups to convert aza-BODIPY in bioconjugate complexes useful for untangling biological processes.
AN ANALYTICAL SOLUTION TO THE PERSPECTIVE-N-POINT PROBLEM FOR COMMON PLANAR CAMERA AND FOR CATADIOPTRIC SENSOR (2008)

The Perspective-N-Point problem (PNP) is a notable problem in computer vision. It consists of given N points known in an object coordinate space and their projection onto the image, estimating the distance between the video camera and the set of points. By the use of an unusual formulation, we propose a method to get a strictly analytical solution based on the resolution of linear systems. This solution can be computed instantly and is well adapted to real time computer vision applications. Our approach is general enough to work with a nonlinear sensor like a catadioptric panoramic sensor. To improve the localization accuracy, we also provide a technique to correct geometrical distortion. This algorithm also corrects little errors on intrinsic and extrinsic parameters. Well implemented, this correction can be performed in real time.

Recent advances in coeliac disease (2006)

he management of coeliac disease is an increasing part of a gastroenterologist's workload. Recent prevalence studies suggest ,1% of the general UK population have positive coeliac serology, which combined with increasing population and primary care awareness is leading to more and more referrals. The majority of contemporary referrals are now initially diagnosed by highly sensitive and specific serological tests followed by readily performed endoscopic biopsy (fig Consequently, we now identify many more patients with no or only mild clinical symptoms, making the classical scenario of diarrhoea/steatorrhoea and weight loss a comparative rarity. Much of the early data on clinical aspects of classical coeliac disease (that is, published pre ,1990) may not be applicable to contemporary coeliac disease. These changes in clinical practice have been paralleled by a dramatic increase in our knowledge of disease pathogenesis, making coeliac disease the best understood human ''autoimmune'' disorder. In this review article, we present selected major recent advances in both clinical and basic science aspects of coeliac disease, focusing on the many high quality studies published within the last five years.
