Rock painting and petroglyph recording projects in Canada

Rock paintings, pictographs, and petroglyphs are vulnerable to natural weathering and threatened by vandalism. Photography can provide accurate records of rock art sites for posterity, interpretation, and research. Photographic methods for red ocher rock paintings in the Canadian shield were investigated, including infrared photography, infrared luminescence, and false-color infrared; ultraviolet reflected and fluorescence photography; and cross-polarization using electronic flash. High contrast copy film with a blue filter was found to be useful. Camera stability, color temperature, film format, and exposure and color reproduction controls are discussed. Digital image processing was found to be applicable to the enhancement of photographic images of rock paintings. The photographic and photogrammetric recording of three sites from the frozen surface of the Churchill River is described. Methods for recording petroglyphs are reviewed. These have included tracing, rubbing, molding, and casting. Electronic flash raking light photography at night and stereophotogrammetry were undertaken at a petroglyph site in marble in Ontario. Machine vision systems, for example, laser scanners, could eventually find application in petroglyph recording and replication. The article includes a comprehensive bibliography of rock art recording methods.
Employers' perspectives on work-integrated learning in project-based workplaces

The property and construction industry is uniquely impacted by project-based work environments; this creates special challenges for collaborative education. This research is based on investigating the attitudes of employer’s towards the use of formally assessed internships. The study comprised two stages; firstly a series of pilot interviews were undertaken with employers to test a number known issues. Secondly, the results from the interviews were used to refine a set of questions that were put to a large focus group of employers who were invited from across the property and construction sector. The results showed that many organisations expressed considerable goodwill towards collaborative education with universities. However, the challenges caused by project-based work environments restricted their ability to provide comprehensive learning opportunities. This research focuses on the distinctive issues associated with work-integrated learning in the property and construction industry
Abstract 9115: Determining Optimal Hemoglobin Transfusion Threshold for Patients With Severe Traumatic Brain Injury: A Systematic Review and Meta-Analysis

Introduction: Multiple randomized controlled trials have found that a conservative approach to transfusing critically ill patients reduces mortality, with current guidelines recommending a hemoglobin (HgB) transfusion threshold of 7 g/dL. However, little work has examined whether this transfusion threshold reduces mortality in patients with severe traumatic brain injury (TBI). Here, we present a systematic review and meta-analysis of the literature. Methods: A systematic search was conducted on PubMed, Ovid, and Web of Science. Full-text articles were eligible if patients with TBI, defined as Glasgow Coma Score <= 8, were divided into multiple groups with varying hemoglobin transfusion thresholds and reported any outcome of interest including mortality, number of packed red blood cell (PRBC) units transfused, length of stay in ICU, and length of stay in the hospital. Eight studies were eligible (n = 3663). We compared mortality rates at HgB transfusion thresholds of < 7 g/dL, < 8 g/dL, < 9 g/dL, and < 10 g/dL. Results: We found that traditionally ‘conservative’ approaches to anemia management (HgB < 7 g/dL, < 8 g/dL, and < 9 g/dL) were associated with decreased mortality when compared to traditionally ‘liberal’ approaches (HgB < 10 g/dL), with p < 0.05. Results were robust across both frequentist and Bayesian analysis. As a surrogate for cost of care and use of hospital resources, the total number of PRBC units transfused to patients, length of stay in ICU, and length of stay in hospital were analyzed. We found that using a transfusion threshold < 7 g/dL compared to < 10 g/dL substantially decreased the number of PRBC units transfused. In three of five cohorts, the cohort with the lower HgB transfusion threshold or no transfusion had a significantly shorter length of stay in the ICU and in the hospital. The remaining two cohorts found no significant difference in the length of stays in ICU or hospital. Conclusion: This study demonstrates that conservative approaches to transfusions ( < 7 g/dL, < 8 g/dL, or < 9 g/dL) significantly reduce mortality and the number of PRBC units transfused when compared to more liberal approaches ( < 10 g/dL). Current evidence is unclear on the benefits of conservative approaches in reduction of ICU or hospital length of stay.
Characteristics of Thermo-Electromotive Force, Electric Current and Electric Resistance in Intermittent Cutting Process by Face Milling

Tool-work thermo-electromotive force (E.M.F.) is very important signal because it is regarded as the evidence of direct cutting phenomenon at the cutting position.Our aim is to carry out in-process monitoring of tool wear under intermittent cutting conditions. We examined the relation between E.M. F. and tool flank wear to explore the possibility of in-process tool wear detection using E.M. F. Waveform variations in E.M. F. signals corresponding to tool flank wear were observed at the starting position of cut. To determine the cause of these waveform variations, the electric current was also measured and the electric resistance between the tool and work piece were calculated using Ohm's law. It is found that the change in the tool-work electric resistance corresponds to the progression of the tool flank wear.By monitoring this tool-work electric resistance, it is possible to conduct in-process detection of tool flank wear.
A high-end mask writer using a spatial light modulator

This paper presents the properties of the Sigma7300 which is a commercial DUV laser pattern generator based on spatial light modulator (SLM) technology designed to meet the requirements of the 65-nm technology node and below. The introduction of spatial light modulators provides a possibility for optical mask writers to combine high resolution and accuracy with short write time making it possible to write most of the high end mask layers in a cost effective way. The Sigma7300 mask writer is developed by Micronic Laser Systems whereas the SLM, which is a combined MEMS and CMOS component with individually controllable movable micromirrors, is developed by the Fraunhofer-IPMS institute in Dresden. The SLM allows parallel writing of one million pixels with a frame rate of up to 2 kHz. The technology offers resolution enhancement advantages from stepper technology not available in other mask patterning tools.
Inhibition of LPMOs by Fermented Persimmon Juice

Fermented persimmon juice, Kakishibu, has traditionally been used for wood and paper protection. This protective effect stems at least partially from inhibition of microbial cellulose degrading enzymes. The inhibitory effect of Kakishibu on lytic polysaccharide monooxygenases (LPMOs) and on a cocktail of cellulose hydrolases was studied, using three different cellulosic substrates. Dose dependent inhibition of LPMO activity by a commercial Kakishibu product was assessed for the well-characterized LPMO from Thermoascus aurantiacus TaAA9A, and the inhibitory effect was confirmed on five additional microbial LPMOs. The model tannin compound, tannic acid exhibited a similar inhibitory effect on TaAA9A as Kakishibu. It was further shown that both polyethylene glycol and tannase can alleviate the inhibitory effect of Kakishibu and tannic acid, indicating a likely mechanism of inhibition caused by unspecific tannin–protein interactions.
Meta-Learning for Fast Adaptive Locomotion with Uncertainties in Environments and Robot Dynamics

This work developed meta-learning control policies to achieve fast online adaptation to different changing conditions, which generate diverse and robust locomotion. The proposed method updates the interaction model constantly, samples feasible sequences of actions of estimated state-action trajectories, and then applies the optimal actions to maximize the reward. To achieve online model adaptation, our proposed method learns different latent vectors of each training condition, which is selected online based on newly collected data from the past 10 samples within 0.2s. Our work designs appropriate state space and reward functions, and optimizes feasible actions in an MPC fashion which are sampled directly in the joint space with constraints, hence requiring no prior design or training of specific gaits. We further demonstrated the robot’s capability of detecting unexpected changes during the interaction and adapting the control policy in less than 0.2s. The extensive validation on the SpotMicro robot in a physics simulation shows adaptive and robust locomotion skills under changing ground friction, external pushes, and different robot dynamics including motor failures and the whole leg amputation.
Tertiary education learning outcomes, a case study: “You want us to think!”

Present perceptions about the poor production of university students in the last decades might be the same other professors had in previous centuries. Nonetheless, more corseting forms of assessment and the irruption of new technologies can establish a difference. These factors serve the controversy when blamed for preventing intellectual development, or when also considering that ICTs are the personal mark of new generations of youths who face their outdated dinosaur teachers. The purpose of this paper is to provide a tentative case analysis of the situation to validate what seems a generalized perception of the decay of tertiary education. Our data will be obtained from answers that students of the third year of a Humanities English degree could not provide. In our approach we will consider the difficulties students have in reaching the highest levels of taxonomies like Bloom’s (1956) or Dreyfus & Dreyfus (1980) with their further modifications. Collaterally we will tackle key competences and forms of assessment. Results will present the dichotomy of maintaining the present progression or, alternatively, think again and take some action.
Phylogenetic Groups and Antimicrobial Resistance Genes in Escherichia coli from Different Meat Species

Escherichia coli isolated from meat of different animal species may harbour antimicrobial resistance genes and may thus be a threat to human health. The objectives of this study were to define antimicrobial resistance genes in E. coli isolates from pork, beef, chicken- and turkey meat and analyse whether their resistance genotypes associated with phylogenetic groups or meat species. A total number of 313 E. coli samples were isolated using standard cultural techniques. In 98% of resistant isolates, a dedicated resistance gene could be identified by PCR. Resistance genes detected were tet(A) and tet(B) for tetracycline resistance, strA and aadA1 for streptomycin resistance, sulI and sulII for resistance against sulphonamides, dfr and aphA for kanamycin resistance and blaTEM for ampicillin resistance. One stx1 harbouring E. coli isolated from pork harboured the tet(A) gene and belonged to phylogenetic group B2, whilst another stx1 positive isolate from beef was multi-resistant and tested positive for blaTEM, aphA, strA–B, sulII, and tet(A) and belonged to phylogenetic group A. In conclusion, the distribution of resistance elements was almost identical and statistically indifferent in isolates of different meat species. Phylogenetic groups did not associate with the distribution of resistance genes and a rather low number of diverse resistance genes were detected. Most E. coli populations with different resistance genes against one drug often revealed statistically significant different MIC values.

Simulation results show that: The diagnosis system of inter-turn fault based on WPA and BP neural network can effectively identify short-circuit fault between ratios. This is to say that the method has a high fault diagnosis rate.

Quantum optimal control of ten-level nuclear spin qudits in 
Sr87

We study the ability to implement unitary maps on states of the $I=9/2$ nuclear spin in \textsuperscript{87}Sr, a $d=10$ dimensional (qudecimal) Hilbert space, using quantum optimal control. Through a combination of nuclear spin-resonance and a tensor AC-Stark shift, by solely modulating the phase of a radio-frequency magnetic field, the system is quantum controllable. Alkaline earth atoms, such as \textsuperscript{87}Sr, have a very favorable figure-of-merit for such control due to narrow intercombination lines and the large hyperfine splitting in the excited states. We numerically study the quantum speed-limit, optimal parameters, and the fidelity of arbitrary state preparation and full SU(10) maps, including the presence of decoherence due to optical pumping induced by the light-shifting laser. We also study the use of robust control to mitigate some dephasing due to inhomogeneities in the light shift. We find that with an rf-Rabi frequency of $\Omega_\text{rf}$ and 0.5\% inhomogeneity in the the light shift we can prepare an arbitrary Haar-random state in a time $T={4.5}\pi/\Omega_\text{rf}$ with average fidelity $\langle \mathcal{F}_\psi \rangle =0.9992$, and an arbitrary Haar-random SU(10) map in a time $T=24\pi/\Omega_\text{rf}$ with average fidelity $\langle \mathcal{F}_U \rangle = 0.9923$.
The new optimization method of Q-switched quasi-three-level lasers

The aim of work is to develop efficient theoretical model enabling analysis and optimization of Q-switched quasi-threelevel lasers. The model consists of two parts: pumping part and Q-switched part, which can be separated in a case of active Q-switching regime. For the pumping of quasi-three-level gain medium the semi-analytical model was developed, enabling the calculations for average occupation of upper laser level for given pump power and pump duration, spatial pump beam profile, length and dopant level of gain medium. Moreover, ground-state-depletion, up-conversion parasitic relaxation and temperature effects were considered in the model. The new approach for optimization of CW regime of quasi-three-level lasers was developed for Q-switched lasers operating with high repetition rates. Moreover, for long pump durations comparable to laser upper level lifetimes, the optimization procedure based on Lagrange multiplier technique was developed. The simple analytical formulae for effective pump duration needed to achieve the quasistationary inversion for given pump power density and up-conversion parameter were derived. The model enables the optimization of gain medium length and absorbance, average pump area and out-coupling losses for wide class of quasithree- level lasers.
Downing a Rogue Drone with a Team of Aerial Radio Signal Jammers

This work proposes a novel distributed control framework in which a team of pursuer agents equipped with a radio jamming device cooperate in order to track and radio-jam a rogue target in 3D space, with the ultimate purpose of disrupting its communication and navigation circuitry. The target evolves in 3D space according to a stochastic dynamical model and it can appear and disappear from the surveillance area at random times. The pursuer agents cooperate in order to estimate the probability of target existence and its spatial density from a set of noisy measurements in the presence of clutter. Additionally, the proposed control framework allows a team of pursuer agents to optimally choose their radio transmission levels and their mobility control actions in order to ensure uninterrupted radio jamming to the target, as well as to avoid the jamming interference among the team of pursuer agents. Extensive simulation analysis of the system’s performance validates the applicability of the proposed approach.
Fundamental frequency extraction method based on the p-th power of amplitude spectrum with band limitation

The extraction of the fundamental frequency of speech is an important issue in many speech processing fields. In this paper, we propose a fundamental frequency extraction method based on the power of the amplitude spectrum in the bandwidth where the fundamental frequency is present. This method varies the power of the amplitude spectrum depending on the signal-to-noise ratio (SNR) of the input speech signal in each analysis frame. Therefore, in a white noise environment, this method is applicable to a wide range of speech signals from a high signal-to-noise ratio to a low signal-to-noise ratio. By conducting preliminary tests using true vowels, we derive the equation representing the relationship between the power of the amplitude spectrum and the signal-to-noise ratio. This is also applied to real continuous speech, and the superiority of the proposed method is clearly demonstrated in comparative tests with conventional methods. © 2007 Wiley Periodicals, Inc.

Internet-Delivered Cognitive Behavioral Therapy for Generalized Anxiety Disorder in Nationwide Routine Care: Effectiveness Study

Background Therapist-supported, internet-delivered cognitive behavioral therapy (iCBT) is efficacious for generalized anxiety disorder (GAD), but few studies are yet to report its effectiveness in routine care. Objective In this study, we aim to examine whether a new 12-session iCBT program for GAD is effective in nationwide routine care. Methods We administered a specialized, clinic-delivered, therapist-supported iCBT for GAD in 1099 physician-referred patients. The program was free of charge for patients, and the completion time was not predetermined. We measured symptoms with web-based questionnaires. The primary measure of anxiety was the GAD 7-item scale (GAD-7); secondary measures were, for pathological worry, the Penn State Worry Questionnaire and, for anxiety and impairment, the Overall Anxiety Severity and Impairment Scale. Results Patients completed a mean 7.8 (SD 4.2; 65.1%) of 12 sessions, and 44.1% (485/1099) of patients completed all sessions. The effect size in the whole sample for GAD-7 was large (Cohen d=0.97, 95% CI 0.88-1.06). For completers, effect sizes were very large (Cohen d=1.34, 95% CI 1.25-1.53 for GAD-7; Cohen d=1.14, 95% CI 1.00-1.27 for Penn State Worry Questionnaire; and Cohen d=1.23, 95% CI 1.09-1.37 for Overall Anxiety Severity and Impairment Scale). Noncompleters also benefited from the treatment. Greater symptomatic GAD-7–measured relief was associated with more completed sessions, older age, and being referred from private or occupational care. Of the 894 patients with a baseline GAD-7 score ≥10, approximately 421 (47.1%) achieved reliable recovery. Conclusions This nationwide, free-of-charge, therapist-supported HUS Helsinki University Hospital–iCBT for GAD was effective in routine care, but further research must establish effectiveness against other treatments and optimize the design of iCBT for GAD for different patient groups and individual patients.
Full-Scale Destructive Bridge Test Allows Prediction of Ultimate Capacity

Contemporary bridge design is generally based on designing individual members for the maximum force effect that each member may experience. This approach ignores the system-level interactions of these individual members, which may greatly increase the ultimate strength of the complete structure. In an attempt to understand better the load redistribution mechanisms that lead to this increase in ultimate strength, the destructive testing of a skewed steel I-girder bridge was planned and executed. However, because of the enormous system-level reserve capacity of the structure, the structure generally responded elastically, despite being loaded with the equivalent of 17 HS-20 design vehicles. Thus, a validated finite element analysis (FEA) approach was used to predict the ultimate capacity of this structure and to analyze the force redistribution as the bridge's elastic limit was exceeded. The FEA results predicted that the equivalent of 41 HS-20 vehicles was needed to plastify fully the four girders of the subject bridge and show the significant amount of yielding that occurs in the cross-frames when the ultimate capacity of the girders is achieved.
An absorptive capacity interpretation of Six Sigma

Purpose – The Six Sigma approach to business improvement has emerged as a phenomenon in both the practitioner and academic literature with potential for achieving increased competitiveness and contributing. However, there is a lack of critical reviews covering both theory and practice. Therefore, the purpose of this paper is to critically review the literature of Six Sigma using a consistent theoretical perspective, namely absorptive capacity.Design/methodology/approach – The literature from peer‐reviewed journals has been critically reviewed using the absorptive capacity framework and dimensions of acquisition, assimilation, transformation, and exploitation.Findings – There is evidence of emerging theoretical underpinning in relation to Six Sigma borrowing from an eclectic range of organisational theories. However, this theoretical development lags behind practice in the area. The development of Six Sigma in practice is expanding mainly through more rigorous studies and applications in service‐based envi.
