Abstract
The magnetic sensor properties of magnetic tunnel junctions (MTJs) with a superparamagnetic (SP) free layer were systematically investigated at low frequencies (<10 Hz). We prepared four varieties of MTJs with various SP properties by changing the annealing temperature. The temperature dependence of magnetoresistance curves and the signal/noise property at 285 K were evaluated. We found that the SP free layer has the advantage of detecting very small and low-frequency AC magnetic fields compared with a ferromagnetic free layer. The SP free layer strongly suppressed magnetic 1/f noise at low frequencies and expressed a very linear response to a small magnetic field. The obtained properties in MTJs with the SP free layer are suitable for detecting biomagnetic fields. The detectivity was 111 nT at low frequencies (from 0.1 to 10 Hz), which is one of the highest values in single-MTJ sensors.

Moreover, the "water" springs of the Karia Region, and mainly the Milas Region and Inner Karia that also include Labraunda, that are still important today; and the structures related to these springs that bestow a privileged importance to this region still didn't completely receive the attention they deserve. The "Water Complex" structure, which was discovered unexpectedly during the rearrangement works focused around Temenos will be very useful to resolve the water system mechanism developed in Labraunda, which takes its holy properties from water.

All-optical switching using a new photonic crystal directional coupler
Authors: Vakili B. , Bahadori-Haghighi S. , Ghayour R. 
Published: November 2016

In this paper all-optical switching in a new photonic crystal directional coupler is performed. The structure of the switch consists of a directional coupler and a separate path for a control signal called “control waveguide”. In contrast to the former reported structures in which the directional couplers are made by removing a row of rods entirely, the directional coupler in our optical switch is constructed by two reduced-radius line-defect waveguides separated by the control waveguide. Furthermore, in our case the background material has the nonlinear Kerr property. Therefore, in the structure of this work, no frequency overlap occurs between the control waveguide mode and the directional coupler modes. It is shown that such a condition provides a very good isolation between the control and the probe signals at the output ports. In the control waveguide, nonlinear Kerr effect causes the required refractive index change by the presence of a high power control (pump) signal. Even and odd modes of the coupler are investigated by applying the distribution of the refractive index change in the nonlinear region of a super-cell so that a switching length of about 94 µm is obtained at the wavelength of 1.55 µm. Finally, all-optical switching of the 1.55 µm probe signal using a control signal at the wavelength of 1.3 µm, is simulated through the finite-difference time-domain method, where both signals are desirable in optical communication systems. A very high extinction ratio of 67 dB is achieved and the temporal characteristics of the switch are demonstrated.

Authors: Baccouch C. , Bouchouicha D. , Sakli H. , Aguili T. 
Published: November 2016

The present work was to use photovoltaic solar cells in patch antenna structures. The radiating patch element of a patch antenna was replaced by a solar cell. Direct Current (DC) generation remained the original feature of the solar cell, but additionally it was now able to receive and transmit electromagnetic waves. Here, we used a new patch antenna structure based on a photovoltaic solar cell. It was then used to collect photo-generated current as well as Radio Frequency (RF) transmission. A mathematical model which would serve the minimization of power losses of the cell and therefore the improvement in the conversion efficiency was studied. A simulation allowed analysing the performance of the antenna, with a silicon material, and testing its parameters such as the reflection coefficient (S11), gain, directivity and radiated power. The performance analysis of the solar cell patch antenna was conducted using Advanced Design System (ADS) software. Simulation results for this antenna showed a dual resonance frequency of 5.77 GHz and of 6.18 GHz with an effective return loss of -38.22dB and a gain of 1.59dBi.

Early Complications After Percutaneous Closure of Atrial Septal Defect in Infants with Procedural Weight Less than 15 kg
Authors: Tanghöj Gustaf , Odermarsky Michal , Naumburg Estelle , Liuba Petru 
Published: November 2016

AbstractAtrial septal defect (ASD) is the most common congenital cardiac lesion accounting for 10–15% of all cardiac malformations. In the majority of cases, the secundum type of the ASD is closed percutaneously in the catheterization laboratory. Although transcatheter closure of ASD is considered safe and effective in pediatric patients, there are limited data regarding the efficacy and safety of device ASD closure in smaller infants. The aim of this study was to determine risk of complications within 72 h following device closure of ASD in children of body weight <15 kg compared to larger children. Overall 252 children who underwent transcatheter closure of ASD at Children’s Heart Centre in Lund, Sweden, between 1998 and 2015 were included. Data regarding demographics, comorbidity and complications occurring during and after device procedure until discharge were retrieved from the hospital’s databases. Echocardiographic data were obtained from the digital and videotape recordings. Nearly half of the study cohort (n = 112; 44%) had a procedural weight <15 (median 11.3) kg with a median procedural age of 2.02 years. Among this study group, 22 (9%) children had post-procedural in-hospital complications, of which 16 (7%) were considered as major and six (2%) considered as minor. No deaths occurred. There was no significant difference in of the occurrence of major or minor complications between the two groups (p = 0.32). Larger ASD was more often associated with minor complications, OR 1.37 (95% CI 0.99–1.89), which most often consisted of transient arrhythmias during or after the procedure. Percutaneous ASD device closure can be performed safely in low-weight infants with a risk of post-procedural in-hospital complications comparable to larger/older children. Nevertheless, careful considerations of the indications to device closure is needed, particularly in children with larger ASD, as recommended by the current international guidelines for ASD closure.
Safety degree assessment of drugs used in conscious sedation for colonoscopy in patients that develop respiratory depression

Published: November 2016

Abstract
Objective To analyze the safety degree of drugs used in colonoscopy during conscious sedation in patients developing respiratory depression.
Methods Cross-sectional observational study that evaluated 1120 patients who underwent colonoscopy between February 2015 and February 2016. Physical characteristics, surgical history and previous colonoscopies, indication and conditions of the current examination, fentanyl and midazolam doses and subsequent complications were analyzed. Level of significance: p < 0.05. Chi-square test was used for association of categorical variables, whereas Student's t test was used to compare means and Spearman's coefficient for correlation.
Results There were 661 female (59%) and 459 (41%) male patients, with a mean age of 54.90 (20–87) years and BMI of 27.00 (14.5–45.4). Of the 1120 patients, only 2 (0.2%) had respiratory depression, reversed with lanexat. Patients who had complications were of both genders, with a body mass index of 21.25 and 28.7. There was a correlation between the required dose of fentanyl and age (p < 0.001 to −0.121 Spearman's coefficient), as well as midazolam (p < 0.001 – Spearman's coefficient −0.452) and increasing age was associated with a lower dose of the drug.
Conclusion The number of patients with complications was 0.17%. The age of the patient showed an inverse association, i.e., the older the patient, the lower the required dose of medication. The drugs used in colonoscopy show a high degree of safety, corroborating their frequent use for superficial/conscious sedation in this procedure.
“Not Bad Kids, Just Bad Choices”: Governing School Safety Through Choice
Authors: Levinsky Zachary 
Published: November 2016

AbstractUsing the Safe Schools Act in Ontario as an example of a school zero-tolerance policy, I demonstrate that there are more implications for governing students through these policies than the literature tends to suggest. The push to exclude students found in zero-tolerance policies co-exists uneasily with the liberal democratic pull to an inclusive education. Principals negotiate the contradictory positioning of students as simultaneously excludable and includable uniquely. There is also an insertion of ‘choice’ as a strategy to resolve these tensions. Inappropriate conduct conceived as the students’ choice signals a reorientation of the main function of the school, to an institution now interested in managing its own reputation by devolving the responsibility of good behaviour onto the student.
Protecting Research Confidentiality via the Wigmore Criteria: Some Implications of Parent and Bruckert v The Queen and Luka Rocco Magnotta
Authors: Palys Ted , MacAlister David 
Published: November 2016

Abstract
There have been two significant legal challenges to research confidentiality in Canada. The first occurred because of a Coroner’s subpoena, with the researcher invoking the Wigmore criteria and winning a researcher-participant privilege. A second case saw two University of Ottawa researchers served with a search warrant for the tape and transcript of an interview they had conducted years earlier with an individual subsequently accused of murder. The researchers defended research confidentiality in Quebec Superior Court, winning a qualified researcher-participant privilege in the process. This article discusses implications of the court’s decision for researchers, research ethics boards, and universities for the future defence of research confidences. All have a role to play in designing research that anticipates the court’s evidentiary requirements when a claim of privilege is invoked to help ensure future jurisprudence is as favourable to research participants and as respectful of academic freedom as possible.
