Using dual eye tracking to uncover personal gaze patterns during social interaction
Authors: Rogers Shane L. , Speelman Craig P. , Guidetti Oliver , Longmuir Melissa
Published: March 2018

We report the personal eye gaze patterns of people engaged in face-to-face getting acquainted conversation. Considerable differences between individuals are underscored by a stability of eye gaze patterns within individuals. Results suggest the existence of an eye-mouth gaze continuum. This continuum includes some people showing a strong preference for eye gaze, some with a strong preference for mouth gaze, and others distributing their gaze between the eyes and mouth to varying extents. Additionally, we found evidence of within-participant consistency not just for location preference but also for the duration of fixations upon the eye and mouth regions. We also estimate that during a 4-minute getting acquainted conversation mutual face gaze constitutes about 60% of conversation that occurs via typically brief instances of 2.2 seconds. Mutual eye contact ranged from 0–45% of conversation, via very brief instances. This was despite participants subjectively perceiving eye contact occurring for about 70% of conversation. We argue that the subjective perception of eye contact is a product of mutual face gaze instead of actual mutual eye contact. We also outline the fast activity of gaze movements upon various locations both on and off face during a typical face-to-face conversation.
An accurate first-principles treatment of doping-dependent electronic structure of high-temperature cuprate superconductors

Published: March 2018

A first-principles density-functional description of the electronic structures of the high-Tc cuprates has remained a long-standing problem since their discovery in 1986, with calculations failing to capture either the insulating (magnetic) state of the pristine compound or the transition from the insulating to metallic state with doping. Here, by taking lanthanum cuprate as an exemplar high-Tc cuprate, we show that the recently developed non-empirical, strongly constrained and appropriately normed density functional accurately describes both the antiferromagnetic insulating ground state of the pristine compound and the metallic state of the doped system. Our study yields new insight into the low-energy spectra of cuprates and opens up a pathway toward wide-ranging first-principles investigations of electronic structures of cuprates and other correlated materials.
Three-observer classical dimension witness violation with weak measurement
Authors: Li Hong-Wei , Zhang Yong-Sheng , An Xue-Bi , Han Zheng-Fu , Guo Guang-Can
Published: March 2018

Dimension is an important resource in quantum information theory. Based on weak measurement technology, we propose the three-observer dimension witness protocol in a prepare-and-measure setup. By applying the dimension witness inequality based on the quantum random access code and the nonlinear determinant value, we demonstrate that double classical dimension witness violation is achievable if we choose appropriate weak measurement parameters. Analysis of the results will shed new light on the interplay between the multi-observer quantum dimension witness and the weak measurement technology, which can also be applied in the generation of semi-device-independent quantum random numbers and quantum key distribution protocols.

Inquiry and industry inspired laboratories: the impact on students’ perceptions of skill development and engagements
Authors: George-Williams Stephen R. , Soo Jue T. , Ziebell Angela L. , Thompson Christopher D. , Overton Tina L.
Published: March 2018

Many examples exist in the chemical education literature of individual experiments, whole courses or even entire year levels that have been completely renewed under the tenets of context-based, inquiry-based or problem-based learning. The benefits of these changes are well documented and include higher student engagement, broader skill development and better perceived preparation for the workforce. However, no examples appear to have been reported in which an entire school's teaching laboratory programme has been significantly redesigned with these concepts in mind. Transforming Laboratory Learning (TLL) is a programme at Monash University that sought to incorporate industry inspired context-based, inquiry-based and problem-based learning into all the laboratory components of the School of Chemistry. One of the ways in which the effect of the programme was evaluated was through the use of an exit survey delivered to students at the completion of seven experiments that existed before the TLL programme as well as seven that were generated directly by the TLL programme. The survey consisted of 27 closed questions alongside three open questions. Overall, students found the new experiments more challenging but recognised that they were more contextualised and that they allowed students to make decisions. The students noted the lack of detailed guidance in the new laboratory manuals but raised the challenge, context and opportunity to undertake experimental design as reasons for enjoying the new experiments. Students' perceptions of their skill development shifted to reflect skills associated with experimental design when undertaking the more investigation driven experiments. These results are consistent with other literature and indicate the large scale potential success of the TLL programme, which is potentially developing graduates who are better prepared for the modern workforce.

Patient Acceptance of Invasive Treatments for Tinnitus
Authors: Smit Jasper V. , Pielkenrood Bart J. , Arts Remo A. G. J. , Janssen Miranda L. , Temel Yasin , Stokroos Robert J.
Published: March 2018

Purpose

The field of neuromodulation is currently seeking to treat a wide range of disorders with various types of invasive devices. In recent years, several preclinical trials and case reports in humans have been published on their potential for chronic tinnitus. However, studies to obtain insight into patients' willingness to undergo these treatments are scarce. The aim of this survey study was to find out whether tinnitus patients are willing to undergo invasive neuromodulation when taking its risks, costs, and potential benefits into account.

Method

A Visual Analog Scale (VAS, 0–10) was used to measure the outcome. Spearman's rank-order correlation coefficients were computed to determine the correlation between patient characteristics and acceptance rates.

Results

Around one fifth of the patients were reasonably willing to undergo invasive treatment (VAS 5–7), and around one fifth were fully willing to do so (VAS 8–10). Hearing aids, used as a control, were accepted most, followed by cochlear implantation, deep brain stimulation, and cortical stimulation. Acceptance rates were slightly higher when the chance of cure was higher. Patients with a history of attempted treatments were more eager than others to find a new treatment for tinnitus.

Conclusions

A considerable proportion of patients with tinnitus would accept a variety of invasive treatments despite the associated risks or costs. When clinical neuromodulatory studies for tinnitus are to be performed, particular attention should be given to obtaining informed consent, including explaining the potential risks and providing a realistic outcome expectation.
Switching regulator based on a high‐voltage gain DC–DC converter with non‐pulsating input/output currents
Authors: Mota‐Varona Ricardo , Ortiz‐Lopez Ma Guadalupe , Langarica‐Cordoba Diego , Leyva‐Ramos Jesus
Published: March 2018

In recent years, new technological advances are requiring the use of direct current (DC)–DC switching converters with higher conversion ratios between input and output voltages. Additionally, the desirable characteristics of the converters are non‐pulsating input and output currents as well as a reduced voltage stress on the switching devices. In this work, a control strategy is proposed for the high‐voltage gain converter to regulate the output voltage. The steady‐state operating conditions are discussed as well as the bilinear switching, non‐linear averaged, and linear averaged models. The transfer functions of variables to be used for control purposes are analysed too. Experimental results for a 300 W switching regulator with 97% conversion efficiency are given to validate the controller design procedure.
Physics‐based compact model of integrated gate‐commutated thyristor with multiple effects for high‐power application
Authors: Lyu Gang , Zhuang Chijie , Zeng Rong , Long Teng , Palmer Patrick R.
Published: March 2018

This study presents a physics‐based compact model of the integrated gate‐commutated thyristor (IGCT) with multiple effects for the high‐power application. The proposed model has both acceptable accuracy and computation time requirement, which is suitable for system level circuit simulation and IGCT's whole wafer modelling work. First, the development of IGCT model is discussed and the one‐dimensional phenomenon of IGCT is analysed in this study. Second, a physics‐based compact model of IGCT is proposed. The proposed model of IGCT includes multiple physical effects that are crucial to IGCTs working in high‐power applications. These physical effects include the impact ionisation effect, moving the boundary of the depletion region during the punch‐through and the local lifetime region. The Fourier series solution is applied to the ambipolar diffusion equation in the base region. Third, the proposed model is implemented in Simulink and compared with the model in Silvaco Atlas, a finite‐element tool. Finally, the proposed compact model of IGCT is validated by experiments.

New regulatory tool for the conservation of the geological heritage in France: the Prefectural Decree of the Protection of the Geotope (APPG). Application and feedback in the Yvelines department (Paris basin, Île-de-France)
Authors: Auberger Elise , Gély Jean-Pierre , Merle Didier
Published: March 2018

In France, the conservation of geological heritage has a complex history that dates back to the middle of the 19th century. Two regulatory tools, “Site Classé”, established in 1906, and Natural Reserves, created in 1976, have served to protect geological sites in the past. Nonetheless, these tools are long to implement vis-à-vis to the rapid destruction of geological objects in the French territory. Due to this juridical void, the state created in 2015 two prefectural decrees for the protection of geological sites of interest. These tools allow the Prefect to: (i) determine a departmental list of geological sites of importance; (ii) define appropriate regulations for their conservation through the Prefectural Decree of the Protection of the Geotope (APPG). Their decentralised legal proceedings appear to be easy to administer, as they only require the advice of regional and departmental commissions as well as some local stakeholders. Our article reports the first enactment of the APPG in France, in a peri-urban to urban area, the Yvelines department. By relying on the programmes of Strategy of Creation of Protected metropolitan Areas (SCAP) and the National Inventory of the Geological Heritage (INPG), two geological sites of international value threatened by anthropic activities were selected for the APPG: the Lutetian fossil sites of Grignon and the Ferme de l’Orme. If successfully enacted, the APPG could prove advantageous because it is a tool adapted to the protection of geological objects and to its socio-economic and environmental context. However, after almost two years, the proceedings of the APPG have not been finalised. Optional yet beneficial steps, as well as unforeseen requests, delayed the process considerably. Given that the APPG do not confer protection to the geological sites during this period, their efficacy must be questioned in a fast-evolving region where land pressure is high and geological sites disappear quickly. However, the French juridical system has improved in the recent years in that it encourages Earth Sciences specialists to form part of local consultative instances (CSRPN, CDNPS) and thereby influence the decisions concerning the protection of these highly threatened sites.

More and more follow-up care gets important in the treatment of oncological patients. In addition to detection of recurrent and secondary diseases, the focus should be put particularly on identifying and medicating sequelae associated with therapy. Anamnesis and clinical examination remain at the centre of follow-up treatment. Further contents of follow-up care are based on the disease situation, previous therapies and individual risk factors. For most entities there is no recommendation for routine radiological diagnosis in asymptomatic patients. However, imaging measures are indicated especially when symptoms require clarification. The increasing rate of oral long-term and permanent therapies implies new tasks in after-care. Here, potential side effects have to be registered specifically. Furthermore, treatment success should be monitored regularly.

The interaction of optical and acoustic waves via stimulated Brillouin scattering (SBS) has recently reached on-chip platforms, which has opened new fields of applications ranging from integrated microwave photonics and on-chip narrow-linewidth lasers, to phonon-based optical delay and signal processing schemes. Since SBS is an effect that scales exponentially with interaction length, on-chip implementation on a short length scale is challenging, requiring carefully designed waveguides with optimized opto-acoustic overlap. In this work, we use the principle of Brillouin optical correlation domain analysis to locally measure the SBS spectrum with high spatial resolution of 800 μm and perform a distributed measurement of the Brillouin spectrum along a spiral waveguide in a photonic integrated circuit. This approach gives access to local opto-acoustic properties of the waveguides, including the Brillouin frequency shift and linewidth, essential information for the further development of high quality photonic-phononic waveguides for SBS applications.
Error analysis and new dual-cosine window for estimating the sensor frequency response function from the step response data

Published: March 2018

Aiming at reducing the estimation error of the sensor frequency response function (FRF) estimated by the commonly used window-based spectral estimation method, the error models of interpolation and transient errors are derived in the form of non-parameter models. Accordingly, window effects on the errors are analyzed and reveal that the commonly used hanning window leads to smaller interpolation error which can also be significantly eliminated by the cubic spline interpolation method when estimating the FRF from the step response data, and window with smaller front-end value can restrain more transient error. Thus, a new dual-cosine window with its non-zero discrete Fourier transform bins at −3, −1, 0, 1, and 3 is constructed for FRF estimation. Compared with the hanning window, the new dual-cosine window has the equivalent interpolation error suppression capability and better transient error suppression capability when estimating the FRF from the step response; specifically, it reduces the asymptotic property of the transient error from O(N−2) of the hanning window method to O(N−4) while only increases the uncertainty slightly (about 0.4 dB). Then, one direction of a wind tunnel strain gauge balance which is a high order, small damping, and non-minimum phase system is employed as the example for verifying the new dual-cosine window-based spectral estimation method. The model simulation result shows that the new dual-cosine window method is better than the hanning window method for FRF estimation, and compared with the Gans method and LPM method, it has the advantages of simple computation, less time consumption, and short data requirement; the actual data calculation result of the balance FRF is consistent to the simulation result. Thus, the new dual-cosine window is effective and practical for FRF estimation.
The role of community structure on the nature of explosive synchronization
Authors: Lotfi Nastaran , Rodrigues Francisco A. , Darooneh Amir Hossein
Published: March 2018

In this paper, we analyze explosive synchronization in networks with a community structure. The results of our study indicate that the mesoscopic structure of the networks could affect the synchronization of coupled oscillators. With the variation of three parameters, the degree probability distribution exponent, the community size probability distribution exponent, and the mixing parameter, we could have a fast or slow phase transition. Besides, in some cases, we could have communities which are synchronized inside but not with other communities and vice versa. We also show that there is a limit in these mesoscopic structures which suppresses the transition from the second-order phase transition and results in explosive synchronization. This could be considered as a tuning parameter changing the transition of the system from the second order to the first order.

Published: March 2018

We report measurements of the mechanical properties of two suspended graphene membranes in the temperature range of 80 K to 550 K. For this entire range, the resonant frequency and quality factor of each device were monitored continuously during cooling and heating. Below 300 K, we have additionally measured the resonant frequency's tunability via electrostatic force, and modeled this data to determine graphene's tension and elastic modulus; both of these parameters are found to be strongly temperature-dependent in this range. Above 300 K, we observe a resonant frequency (and therefore tension) minimum near room temperature. This suggests that the thermal expansion coefficient is positive for temperatures below roughly 315 K, and negative for higher temperatures. Lastly, we observe a large, reproducible hysteresis in the resonant frequency as our graphene devices are cycled between 300 K and 550 K. After returning to 300 K, the measured frequency evolves exponentially in time with a time constant of ∼24 h. Our results clash with expectations for pristine graphene membranes, but are consistent with expectations for composite membranes composed of graphene coated by a thin layer of polymer residue.
Trap-assisted transition between Schottky emission and Fowler-Nordheim tunneling in the interfacial-memristor based on Bi2S3 nano-networks

Published: March 2018

For the usage of the memristors in functional circuits, a predictive physical model is of great importance. However, other than the developments of the memristive models accounting bulky effects, the achievements on simulating the interfacial memristance are still insufficient. Here we provide a physical model to describe the electrical switching of the memristive interface. It considers the trap-assisted transition between Schottky emission and Fowler-Nordheim tunneling, and successfully reproduces the memristive behaviors occurring on the interface between Bi2S3 nano-networks and F-doped SnO2. Such success not only allows us uncover several features of the memristive interface including the distribution nature of the traps, barrier height/thickness and so on, but also provides a foundation from which we can quantitatively simulate the real interfacial memristor.

There is a close relationship between the mechanical properties of cells and their physiological function. Non-invasive measurements of the physical properties of cells, especially of adherent cells, are challenging to perform. Through a non-contact optical interferometric technique, we measure and combine the phase, amplitude, and frequency of vibrating silicon pedestal micromechanical resonant sensors to quantify the “loss tangent” of individual adherent human colon cancer cells (HT-29). The loss tangent, a dimensionless ratio of viscoelastic energy loss and energy storage — a measure of the viscoelasticity of soft materials, obtained through an optical path length model, was found to be 1.88 ± 0.08 for live cells and 4.32 ± 0.13 for fixed cells, revealing significant changes (p < 0.001) in mechanical properties associated with estimated nanoscale cell membrane fluctuations of 3.86 ± 0.2 nm for live cells and 2.87 ± 0.1 nm for fixed cells. By combining these values with the corresponding two-degree-of-freedom Kelvin-Voigt model, we obtain the elastic stiffness and viscous loss associated with each individual cell rather than estimations from a population. The technique is unique as it decouples the heterogeneity of individual cells in our population and further refines the viscoelastic solution space.

The ability to identify precise cancer margins in vivo during a surgical excision is critical to the well-being of the patient. Decreased operative time has been linked to shorter patient recovery time, and there are risks associated with removing either too much or too little tissue from the surgical site. The more rapidly and accurately a surgeon can identify and excise diseased tissue, the better the prognosis for the patient. To this end, we investigate both malignant and healthy oral cavity tissue using the Raman spectroscopy, with a monolithic microsphere-fiber probe. Our results indicate that this probe has decreased the size of the analyzed area by more than an order of magnitude, as compared to a conventional fiber reflection probe. Scanning the probe across the tissues reveals variations in the Raman spectra that enable us to differentiate between malignant and healthy tissues. Consequently, we anticipate that the high spatial resolution afforded by the probe will permit us to identify tumor margins in detail, thereby optimizing tissue removal and improving patient outcomes.
Dual-wavelength GaSb-based mid infrared photonic crystal surface emitting lasers

Published: March 2018

We demonstrate dual-wavelength GaSb-based mid-infrared photonic crystal surface emitting lasers at room temperature. The two lasing peaks emitted simultaneously at 2.3 μm and 2.22 μm under optical pumping. Type-I InGaAsSb quantum wells were used for the active region. The photonic crystal with a rectangular lattice was fabricated on the surface to provide light coupling for laser operation. The two-wavelength operation was a result of the resonances from the two different grating periods along the two perpendicular directions of the rectangular lattice. The laser emissions from these two wavelengths were highly linearly polarized in two perpendicular directions as a result of the grating design.
On the transport, segregation, and dispersion of heavy and light particles interacting with rising thermal plumes
Authors: Lappa Marcello
Published: March 2018

A systematic numerical analysis is carried out on the multiplicity of patterns produced by inertial particles dispersed in a fluid and localized gravitational convection developing in the form of a rising thermal plume. In particular, specific numerical examples are presented to provide inputs for an increased understanding of the underlying flow-particle interaction mechanisms and cause-and-effect relationships. A rich spectrum of convective dynamics is obtained at the relatively high value of the considered Rayleigh number (Ra = 108), which naturally allows the investigation of several intriguing effects (including, but not limited to, particle interaction with plume jet, associated vortices, shear instabilities, and symmetry breaking phenomena). An important degree of freedom is introduced in the problem by changing the particle viscous drag through proper tuning of the related Stokes number (St). Similarly, inertia and weight of solid matter are varied parametrically by performing numerical simulations for both light and heavy particles at different values of the Froude number. This framework lets us identify the average behavior of particles by revealing the mean evolution. We connect such statistics to the behavior of the temporally evolving thermal plume, giving deeper insights into the particle transport mechanisms and associated dissipative dynamics.
