A preliminary study on photoplethysmogram (PPG) signal analysis for reduction of motion artifact in frequency domain (2012)

In this study, we analyzed frequency characteristics of photoplethysmogram (PPG) signal to improve the accuracy of SpO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> by reducing the motion artifacts. 23 kinds of different signals generated by SpO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> test equipment were used for this analysis. The results of analysis showed that most of PPG signals analyzed in this study consisted of the fundamental, 2 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">nd</sup> and 3 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">rd</sup> harmonic components caused by arterial blood flow and component caused by motion artifact. The result also showed the relative magnitudes of its three frequency components. The signals could be divided into four groups based on the relative locations of these frequency components. But four different algorithms would be required to discriminate the signal and motion artifact frequency components.
Power to confuse (2005)

Ever since Nancy Wertheimer of the University of Colorado reported her 1979 findings of an excess of cancer in children living near overhead power lines, seldom has a year passed without a flurry of public debate over the safety or otherwise of these ugly (the one thing all parties agree on) but essential installations.

Much of the argument has been about the very existence of the alleged hazard. As recently as last month, the organisers of the 15 year UK childhood cancer study declared that “perceived risk factors such as living near sources of electromagnetic fields… are not principal causes, if at all, of leukaemia in children.” But a …
A micro-tensile method for measuring mechanical properties of MEMS materials (2008)

Mechanical properties of micro-electro-mechanical systems (MEMS) materials are increasingly important with the wide use of miniaturized systems. This paper proposes a new method for measuring mechanical properties of thin films. This method is suitable for thin films with large strain (>5%) and can be applied to samples with different thicknesses. The S-shaped support springs of the test chip are able to improve the measurement accuracy. Specimens of Ni thin film, with a gauge section 50 µm wide, 100 µm long and 5 µm thick, were tested. The measured Young's modulus of Ni thin film is about 32 GPa and the tensile strength is about 750 MPa.
Cross-Doping Agents for Rutile Masers (1961)

The EPR spectra of nonstoichiometric rutile and rutile doped with tantalum, niobium, and cerium have been examined at helium temperatures. Ta4+ and Nb4+ have short spin-lattice relaxation times and appear to be suitable for cross doping in maser applications.
Paper 2: Education and Training of Engineers in the U.K.A.E.A. (1968)

The U.K.A.E.A. educates and trains its staff over a very wide range of staff and subject matter. A large amount of this is done internally in a number of schools and the paper describes the arguments in favour of this and, in some detail, the way in which it is done. The different groups of the Authority vary somewhat in their methods of training, but the overall principles and objectives are similar. Particular attention is given in the paper to the education and training of already formally qualified engineers because it is in this area that there are particular differences from what is normal practice, and special attention relevant to the nature of the atomic energy industry has to be given.
Comparative genomics on FGF20 orthologs. (2005)

We cloned and characterized human FGF20 in August, 2000. Ohmachi et al claimed the same gene as a novel FGF family member in October, 2000, and Jeffers et al in April, 2001. FGF20 is up-regulated in colorectal cancer due to the activation of WNT/beta-catenin pathway. FGF20 is applicable as the mucosal protective agent for inflammatory bowel disease and chemotherapy/radiation-induced oral mucositis, and also as the inducer of dopaminergic neurons for Parkinson's disease. FGF20 is a target of pharmacogenomics in the field of oncology and regenerative medicine. Here, comparative genomics analyses on FGF20 orthologs were performed. Zebrafish fgf20 gene, consisting of three exons, was located within BX323810.8 genome sequence. Zebrafish fgf20 (208 aa) showed 76.9%, 76.4%, 76.0% and 75.5% total-amino-acid identity with human FGF20, Xenopus fgf20, rat Fgf20 and mouse Fgf20, respectively. Fgf20 orthologs were well conserved among vertebrates. Human FGF20 gene was linked to EFHA2 gene in head-to-head manner with an interval of about 25 kb. FGF20-EFHA2 locus at human chromosome 8p22 and FGF9-EFHA1 locus at human chromosome 13q12.11 were paralogous regions (paralogons) within the human genome. The 5'-flanking promoter region, exonic regions except 3'-UTR, and middle regions within intron 1 were conserved between human FGF20 and mouse Fgf20 genes. Double TCF/LEF binding sites, double EVI1-binding sites, TGIF, PAX4, E47 and AREB6-binding sites were conserved between human FGF20 promoter and mouse Fgf20 promoter.
SAR Images Target Detection Based on YOLOv5 (2021)

Synthetic aperture radar (SAR) images target detection is widely used in military reconnaissance and civil surveillance because of its strong anti-jamming ability. However, the traditional SAR images target detection technology can not be applied to all detection conditions since the feature extraction relies too much on the imaging configuration. With the help of more thorough data analysis, deep learning is undoubtedly the best way to solve this problem, meanwhile it has better generalization capability and generality. In this paper, the author proposed to use latest YOLOv5 as the target detection algorithm network, which has good detection effects for small objects in large scenes; The author also carried out data enhancement, migration learning and other improved optimization methods, comparing with other excellent networks under the same conditions to verify the superiority and flexibility of the method in detection accuracy and speed. The final mean average precision (mAP) reaches 0.994.
Precision wildlife monitoring using unmanned aerial vehicles (2016)

Unmanned aerial vehicles (UAVs) represent a new frontier in environmental research. Their use has the potential to revolutionise the field if they prove capable of improving data quality or the ease with which data are collected beyond traditional methods. We apply UAV technology to wildlife monitoring in tropical and polar environments and demonstrate that UAV-derived counts of colony nesting birds are an order of magnitude more precise than traditional ground counts. The increased count precision afforded by UAVs, along with their ability to survey hard-to-reach populations and places, will likely drive many wildlife monitoring projects that rely on population counts to transition from traditional methods to UAV technology. Careful consideration will be required to ensure the coherence of historic data sets with new UAV-derived data and we propose a method for determining the number of duplicated (concurrent UAV and ground counts) sampling points needed to achieve data compatibility.
Salient advice solutions for a post-fofa environment (2011)

With the Future of Financial Advice (FoFA) legislation due to come into force in July 2012, advisers need to think about which clients will add to revenues when the legislation is enacted, who will want to pay for advice and how to develop an advice proposition that resonates with clients.
Extending workflow-management-systems by a dialogical component (1996)

On top of a cooperative database [9] a dialog system is designed to handle indefinite (vague, imprecise) workflow situat.ions. Issue Based Information Systems (IBIS) are used as an implementation basis and are extended to explanatory dialogs allowing a debate on conclusions, premises and rules. Horizontal and vertical dimensions as well as productive and reductive directions are distinguished in an explanatory dia: log in order to schematize indefinite workflow functions. Successful explanatory dialogs are a valuable aid to process undetermined functions in a way similar to checklists or decisions tables in a conventional definite environment.
Prevalence, identification and distribution of various species of enterococci isolated from clinical specimens with special reference to urinary tract infection in catheterized patients. (2010)

Various clinical specimens were processed to find the prevalence rate of enterococci and to identify the species of clinical isolates of enterococci. Screening of various clinical specimens revealed that enterococci were prevalent in 22.19% of the total specimens, with Foley's catheters and burn wounds to be the major site of isolation. High rate of colonization was noted as opposed to infection. Conventional test scheme proposed by Facklam and Collins were successfully used to speciate enterococcal strains. Seven species of enterococci were identified in the study from a set of 202 cultures, with E.faecalis (49.50%) and E. faecium (35.64%) predominating. E. avium (9.40%), E. hirae (2.47%), E. raffinosus (1.98%) and one isolate each of E.gallinarum and E. casseliflavus were the other members of Enterococcus species identified. Urinary tract infection (UTI) by enterococci due to catherisation was found in 8.92% of the patients and is probably the result of high rate of colonization of Foley's catheters and use of broad-spectrum antibiotics.
Virtual Reality as a Portable Alternative to Chromotherapy Rooms for Stress Relief: A Preliminary Study (2020)

Chromotherapy rooms are comfortable spaces, used in places like special needs schools, where stimuli are carefully selected to cope with stress. However, these rooms are expensive and require a space that cannot be reutilized. In this article, we propose the use of virtual reality (VR) as an inexpensive and portable alternative to chromotherapy rooms for stress relief. We recreated a chromotherapy room stress relief program using a commercial head mounted display (HD). We assessed the stress level of two groups (test and control) through an EEG biomarker, the relative gamma, while they experienced a relaxation session. First, participants were stressed using the Montreal imaging stress task (MIST). Then, for relaxing, the control group utilized a chromotherapy room while the test group used virtual reality. We performed a hypothesis test to compare the self- perceived stress level at different stages of the experiment and it yielded no significant differences in reducing stress for both groups, during relaxing (<i>p</i>-value: 0.8379, α = 0.05) or any other block. Furthermore, according to participant surveys, the use of virtual reality was deemed immersive, comfortable and pleasant (3.9 out of 5). Our preliminary results validate our approach as an inexpensive and portable alternative to chromotherapy rooms for stress relief.
Iron Withholding: A Defense Against Disease (2008)

Excessive and misplaced iron promotes an array of neurodegenerative and endocrine diseases as well as cardiomyopathy, arthropathy, neoplasia and infection. Vertebrates maintain an iron withholding defense system designed to prevent accumulation of redox-active (free) iron in sensitive sites and to sequester the metal in innocuous packages. Numerous genetic, behavioral and environmental factors counteract the defense system. Our increasing awareness of the pathologic roles of iron, as well as of the methods for prevention of iron loading coupled with intensified research and development of tissue specific iron chelator drugs, can be expected to yield marked improvements in human health.
Collaboration in Multi-user Immersive Virtual Environment (2015)

Immersive virtual environment can be used to bring both geographically distributed and co-located users to the same virtual place for collaboration. Compared to remote situations, co-located users collaborate in the same virtual world on top of a shared physical workspace. This collocation allows direct user communication and interaction without computer mediation which facilitates collaborative work. With the development of multi-user display and tracking technology, classical projection-based immersive setups (e.g. CAVE) can now support group immersion for co-located users by offering individual stereoscopic views without visual distortion. In this context, the coexistence of information from the virtual and real world, especially when users do not share a common spatial reference frame, provides users with a new kind of perceptual and cognitive experience. We are interested in how users perceive and communicate with each other to achieve a shared context for collaboration, and how we can broaden supported collaborative scenarios with more flexible viewpoint control.This PhD thesis mainly addresses perceptual and cohabitation issues that we identified in the aim of supporting safe and efficient co-located collaboration in immersive virtual environment. First, we conducted a case study to examine how perceptual conflicts would alter user communication and task performance. Second, we concentrated on the design and evaluation of appropriate navigation paradigms to allow individual virtual navigation while solving cohabitation problems in a shared limited physical workspace. At last, based on the results of previous studies, we designed a generic dynamic navigation model which integrates constrains from the physical workspace and also the virtual world to enable co-located collaboration in multi-user immersive systems.
Precise Exposure Control for Efficient Eye Tracking (2015)

The paper suggests a improved pupil center corneal reflection(PCCR) hardware method to improve the system accuracy. The improved PCCR eye gaze tracking system, a new version of the PCCR eye gaze tracking system supplemented by the relation between IR LED position and the distance from the eye gaze tracking system to the monitor screen, improves the tracking accuracy within one degree, this system, an efficient real-time eye gaze tracking system and its algorithm are proposed in order for people with physical disabilities to be able to access smart device or PC. The system also proposes a circuit that can do power control adaptively between the minimum and maximum power. It is confirmed that the system performs well both for indoors and outdoors in spite of the reduced calculation. Besides, very convenient mouse functions are proposed so that can be used on PC with the eye gaze tracking functions. The user group confirmed their performances that result in high level of satisfaction with excellent tracking function. Above all, the paper suggests the adaptive exposure control algorithm for the proposed system which is robust against light. The adaptive exposure control algorithm presents excellent performance over the existing system for both indoors and outdoors even when the calculation is down to one fifth.
Capacity planning in client - server systems (1996)

The proliferation of client - server systems in business continues unabated, as applications are split into local tasks run on `client' workstations and resource-intensive computations run on a `server' mainframe. The complexity of such systems requires quantitative modelling for their efficient design and reconfiguration throughout their lifetime. The tools and techniques that are needed for the effective performance management of distributed client - server systems are discussed and illustrated by a case study taken from the financial sector.
Wearable Devices in Medical Internet of Things: Scientific Research and Commercially Available Devices (2017)

Wearable devices are now used for a wide range of healthcare observation. One of the most important elements essential in data collection is the sensor. During recent years with improvement in semiconductor technology, sensors have made investigation of a full range of parameters closer to realization.
Fabrication of an ammonia microsensor based on zinc oxide (2013)

The ammonia microsensor is fabricated by the 0.35 μm complementary metal oxide semiconductor (CMOS) process. The sensor is composed of a sensitive film and polysilicon electrodes. Area of the ammonia microsensor is about 1 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> . The sensitive film of the ammonia microsensor is zinc oxide prepared by hydrothermal method. The sensor requires a wet etching process to remove the sacrificial oxide layer and coats the zinc oxide sensitive film on the polysilicon electrodes after the CMOS process. The ammonia microsensor is resistive type. When the sensitive film absorbs or desorbs ammonia gas at room temperature, the sensitive film generates a change in resistance. Experimental results present that the sensitivity of the ammonia microsensor is about 12.6 Ω/ppm at room temperature.
Advantage Gujarat in Spiritual Tourism (2011)

Increase in spiritual tourism in Gujarat is one of the reasons for selecting the industry for the present study. The study would be of greater importance to internal as well as external stakeholders to understand the pattern and the structure of the industry. The prime objective of the present study is to survey profile of spiritual tourism in Gujarat and make suitable suggestions for promotion thereof. The study found that tourist inflow into Gujarat differs significantly between tourists within Gujarat and across the subcontinent as well as domestic and overseas tourists. With infrastructure development and enhancement of core appeal of the spiritual tourist destination, it would be possible to attract more and more tourists to Gujarat. Encouragement of private sector participation in tourism projects would provide employment to local people. Keywords: Spiritual Tourism, Tourism Industry
'Psychological Vulnerabilities' of Adults with Mild Learning Disabilities: Implications for Suspects During Police Detention and Interrogation (2004)

The Police and Criminal Evidence Act 1984 (PACE) and its accompanying guidelines introduced a special safeguard for 'vulnerable' suspects, such as adults with learning disabilities (sometimes known as 'intellectual' or 'developmental' disabilities), during police detention and interviewing. The stated reason for the introduction of this safeguard is that such persons may be 'particularly prone in certain circumstances to provide information which is unreliable, misleading or self incriminating' (Code C, Codes of Practice, Home Office, 1995) and that they are therefore 'at risk' of becoming involved in miscarriages of justice. However, no attempt has been made to specify why suspects with learning disabilities might be more 'vulnerable'.

A disintegrin-metalloproteinase prevents amyloid plaque formation and hippocampal defects in an Alzheimer disease mouse model (2004)

During the preparation of this manuscript for publication, an error was introduced into the Results section, in the fourth sentence of the paragraph beginning with "The levels of the APP-derived soluble peptides Aβ40 and Aβ42 in brains of double-transgenic mice and APP [V717I] control animals at the age of 18 weeks were quantified by specific sandwich ELISAs."The correct sentence appears below.We regret this error.In line ADAM10-mo × APP [V717I] , Αβ40 and Aβ42 were reduced by 49% and 20%, and in line ADAM10-hi × APP [V717I] , by 39% and 29%, respectively.
Kinetic Approaches to Understanding the Mechanisms of Fidelity of the Herpes Simplex Virus Type 1 DNA Polymerase (2010)

We discuss how the results of presteady-state and steady-state kinetic analysis of the polymerizing and excision activities of herpes simplex virus type 1 (HSV-1) DNA polymerase have led to a better understanding of the mechanisms controlling fidelity of this important model replication polymerase. Despite a poorer misincorporation frequency compared to other replicative polymerases with intrinsic 3' to 5' exonuclease (exo) activity, HSV-1 DNA replication fidelity is enhanced by a high kinetic barrier to extending a primer/template containing a mismatch or abasic lesion and by the dynamic ability of the polymerase to switch the primer terminus between the exo and polymerizing active sites. The HSV-1 polymerase with a catalytically inactivated exo activity possesses reduced rates of primer switching and fails to support productive replication, suggesting a novel means to target polymerase for replication inhibition.
