Background: Small for gestational age (SGA) babies are at high risk of perinatal mortality. We aimed to determine the potential to reduce perinatal mortality by improving antenatal detection of SGA babies in Scotland. Methods: We conducted a retrospective population study of all singleton SGA babies born in the 15 Consultant-led maternity units in Scotland in a 3-month period (1st Dec 2014 to 28th Feb 2015 inclusive). Demographic and pregnancy outcome data were extracted from Scottish birth records for all pregnancies; case note review was performed for all SGA cases [defined as birthweight less than the 10th centile for their gestational age at delivery as defined by the appropriate sex-specific UK-WHO Child Growth Standards]. Results: The SGA rate in Scotland was 5.5% (673/12218; 95% confidence interval [CI] 5.1, 5.9) and 27.6% (186/673; 95% CI 24.3, 31.2) of SGA cases were identified prior to delivery. SGA was associated with 18.2% (12/66; 95% CI [10.1%, 30.0%) of all perinatal deaths. The majority (10/12, 83.3%) of SGA babies who died had been identified as SGA in the antenatal period. There was no difference in perinatal mortality whether SGA was detected or not (5.4% [10/186; 95% CI 2.8, 10.0] in the SGA detected group vs 0.4% [2/487 [95% CI 0.3, 2.2] in the non-detected group after adjusting for risk factors for SGA, gestation at delivery and birthweight centile (Adjusted odds ratio [AOR] 0.85 [95% CI 0.5, 1.5], p=0.556). Conclusions: Despite only around a quarter of SGA babies being identified antenatally, the potential to reduce perinatal mortality in the Scottish population by improving SGA detection is limited. Only a minority of perinatal deaths occurred in SGA babies; and in the majority of these SGA was detected antenatally.
Technical aspects of surgical correction of spinal deformities in cerebral palsy
Authors: Mineiro Jorge , Yazici Muharrem 
Published: February 2020

Purpose Cerebral palsy (CP) is a disorder arising from a non-progressive lesion in the developing immature brain with an encephalopathy, that results in various levels of motor and sensory dysfunction. Motor disability of these children can be assessed by the Gross Motor Function Classification System in five levels, and depending on their motor functional capability, the most severely affected children fall into levels IV and V. Children in groups IV and V present a full spectrum of musculoskeletal deformities, among which, scoliosis is the most frequently found spinal deformity that most often requires surgical treatment. However, these are procedures that are usually technically demanding, requiring experienced surgical teams and a multidisciplinary approach. Methods In order to overcome some of the technical pitfalls that may complicate these complex surgical procedures, the authors have gathered together different tips and tricks that may help surgeons performing surgical correction of spinal deformities in CP children. Conclusion Although for these children surgery is a major undertaking, with the multidisciplinary approach and advances of technology, anaesthesia and optimization of pre- and postoperative care, complications are manageable in most cases, improving not only the outcome of surgery but also the patient's quality of life and satisfaction of parents and caretakers.

A dual-band metamaterial absorber based on local surface plasmon resonance is designed, which is composed of a periodic arrangement of stacked nanodisk structures. The structure unit consists of two dielectric layers and three metal layers. Based on the finite difference time domain method, under the condition of vertically incident plane light, two absorption peaks in the mid-wave infrared and long-wave infrared (MWIR/LWIR) are obtained, and the absorption is greater than 98%. The absorber has good incident state tolerance characteristics. We can modulate the MWIR/LWIR absorption peaks by changing the radius of the stacked disk structure, and MWIR and LWIR dual-band broadband absorption can be achieved by integrating different size elements in the plane. The average absorption is 71% for MWIR with 1.1 µm bandwidth from 3.2 to 4.3 µm and 88% for LWIR with 3 µm bandwidth from 8.5 to 11.5 µm. At the same time, the structure also has effective refractive index (RI) sensitivity characteristics. In the RI range of 1.8–2, the maximum RI sensitivity of the LWIR and the MWIR is 1085 nm/refractive index unit (RIU) and 1472 nm/RIU, respectively.
Three-observation-window time-gated algorithm for fluorescence lifetime detection
Authors: Zhu Sihui , Xu Yue , Li Ding 
Published: February 2020

A novel three-observation-window time-gated algorithm that combines overlapped windows and discrete windows together is developed for accurate fluorescence lifetime extraction. The new algorithm adopting a rapid lifetime determination strategy can offer an excellent ability to precisely detect long fluorescence lifetime for fluorescence lifetime imaging microscopy. Monte Carlo simulation indicates that an extremely small relative standard deviation below 0.4% is obtained over a wide fluorescence lifetime range from 5 ns to 30 ns. The detection error of the short fluorescence lifetime less than 5 ns is further reduced by means of an adaptive window width method. In contrast to other algorithms, such as time-correlated single-photon counting and traditional gated-window methods, not only the detection range but also the measurement accuracy is dramatically enhanced.
Exploring the limits for sky and sun glint correction of hyperspectral above-surface reflectance observations
Authors: Groetsch Philipp M. M. , Foster Robert , Gilerson Alexander 
Published: February 2020

Above-surface radiance observations of water need to be corrected for reflections on the surface to derive reflectance. The three-component glint model (3C) [Opt. Express 25, A742 (2017)OPEXFF1094-408710.1364/OE.25.0000A1] was developed to spectrally resolve contributions of sky and sun glint to the surface-reflected radiance signal

Performance and limitations of 3C are assessed for all relevant wind speeds, clear sky atmospheric conditions, illumination/viewing geometries, and sun glint contamination levels. For this purpose, a comprehensive set of

spectra was simulated with a spectrally resolved sky radiance distribution model and Cox–Munk wave slope statistics. Reflectances were also derived from an extensive four-year data set of continuous above-surface hyperspectral observations from the Long Island Sound Coastal Observatory, allowing to corroborate 3C processing results from simulations and measurements with regard to sky and sun glint contributions.

We demonstrated a continuously wavelength-tunable bidirectional passively

Q

-switched fiber laser based on a single-walled carbon nanotube saturable absorber and a bandpass filter (BPF). By tuning the commercial BPF, the

Q

-switched pulse can be obtained in the same cavity at the same pump power in clockwise (CW) and counter-clockwise (CCW) directions. The central wavelength can be continuously tuned from 1520.88 to 1568.56 nm in the CW direction, and from 1520.96 to 1568.64 nm in the CCW direction. A wide tuning range of 48 nm is achieved for two directions in the passively

Q

-switched fiber laser. During the tuning process of the fiber laser, the output pulses with the same central lasing wavelength can be obtained in both oscillation directions owing to the BPF. By increasing the pump power from 130 to 350 mW, the cavity delivers a

Stereo camera trap for wildlife in situ observations and measurements
Authors: Xu Zhongke , Sun Liang , Wang Xinwei , Lei Pingshun , He Jun , Zhou Yan 
Published: February 2020

This paper proposes a stereo camera trap to expand field of view (FOV) of the traditional camera trap and to measure wildlife sizes with a centimeter-scaled accuracy within the detection distance of 10 m. In the method, FOVs of the two cameras are partly overlapped with a 30-cm-long baseline and a posture angle of 100°. Typically only targets in the public FOV can be measured; in contrast, when only parts of targets appear in the public FOV they are difficult to measure. To solve the problem, a part-matching algorithm is provided. In the proposed camera trap, a central process unit is realized by a micro control unit, an advanced reduced-instruction-set-computing machine, and a field-programmable gate array, and then motion sensors trigger the cameras to capture stereo images when animals pass by. In addition, the camera trap has daytime mode and nighttime mode switched by a photosensitive sensor by perceiving ambient lights. Finally, the stereo camera trap data is transmitted by a long-term-evolution module at a scheduled time. Experimental results show that the proposed stereo camera trap can broaden the FOV of a monocular camera by up to 77% at 5 m and estimate feature sizes of targets with centimeter-scaled accuracy.
From 'face-to-face' to 'side-by-side': The abject neighbour in European cinema
Authors: Jeong Seung-hoon 
Published: February 2020

Abstract
The Dardenne brothers' The Promise (1996) and Fatih Akin's The Edge of Heaven (2007) depict non-western migrants in western Europe as the social 'abject' in the background of multicultural conflicts between global (Christian) Europe and its (Islamic) periphery. Also, both share a motif based on the Abraham–Isaac story. Abraham's sacrifice of Isaac epitomizes one's singular relationship with God beyond community (Kierkegaard, Marion, Derrida), but the Abraham figures in the films give themselves to the abject Isaac figures through self-abjection. This becoming-abject as an existential gift breaks the father–son identity in the global regime, forming solidarity among the abject as strangers. Such an abject is, I claim, a 'faceless' third. For Levinas, the 'face of the other' leads one to divine infinity beyond totality, but this self-other unit is destabilized with the other's place taken (repeatedly) by the faceless third. Neither friend nor enemy, this new other should be called 'neighbour' in the context of ethical philosophy. The sovereign-subject-abject hierarchy is dismantled into the equality of the neighbours who share abjectness beyond cultural mediation or identity and walk side by side rather than face to face. I reframe Levinansian infinity in this network of neighbouring on the edge of the global system.

The coral reef was a habitat for several groups of biota that live in this ecosystem. Some species or group species of benthic fauna are known to be ecologically important and others are economically important so that they can be used as indicators to assess reef health. Research on megabenthic fauna in Ternate and its surrounding waters, North Maluku, was carried out in 2012, 2015, 2016, 2017 and 2018 at fourteen permanent stations. The purpose of this study was to determine the fluctuations in several megabenthic faunae temporarily. Data were collected using the modified Belt Transect Method, namely Benthos Belt Transek method. Eight species or groups of megabenthic fauna in the coral reef have been observed. The highest distribution and abundance of megabenthic fauna was coral polyps eating-snail of Drupella spp. The species wealth index decreased from 2012 to 2017 (1.17 to 1.05) but experienced an increase in 2018 (to 1.29). The relatively high dominance found in the megabenthic fauna community was observed in 2015, 2016 and 2017, while in 2012 and 2018 it had relatively low dominance. The megabenthic fauna community observed in 2012 and 2018 has relatively high diversity, whereas in 2015, 2016 and 2017, the diversity is relatively low. The megabenthic fauna community observed in 2012 and 2018 has spread evenly, while in 2015, 2016 and 2017, the relative prevalence of fauna is relatively uneven.

On the Equilibrium Uniqueness in Cournot Competition with Demand Uncertainty
Authors: Leonardos Stefanos , Melolidakis Costis 
Published: February 2020

AbstractWe revisit the linear Cournot model with uncertain demand that is studied in Lagerlöf (2006. “Equilibrium Uniqueness in a Cournot Model with Demand Uncertainty.” The B.E. Journal of Theoretical Economics 6, no. 1. (Topics), Article 19: 1–6.) and provide sufficient conditions for equilibrium uniqueness that complement the existing results. We show that if the distribution of the demand intercept has the decreasing mean residual demand (DMRD) or the increasing generalized failure rate (IGFR) property, then uniqueness of equilibrium is guaranteed. The DMRD condition implies log-concavity of the expected profits per unit of output without additional assumptions on the existence or the shape of the density of the demand intercept and, hence, answers in the affirmative the conjecture of Lagerlöf (2006. “Equilibrium Uniqueness in a Cournot Model with Demand Uncertainty.” The B.E. Journal of Theoretical Economics 6, no. 1. (Topics), Article 19: 1–6.) that such conditions may not be necessary.
F2S3: Robustified determination of 3D displacement vector fields using deep learning
Authors: Gojcic Zan , Zhou Caifa , Wieser Andreas 
Published: February 2020

Abstract
Areal deformation monitoring based on point clouds can be a very valuable alternative to the established point-based monitoring techniques, especially for deformation monitoring of natural scenes. However, established deformation analysis approaches for point clouds do not necessarily expose the true 3D changes, because the correspondence between points is typically established naïvely. Recently, approaches to establish the correspondences in the feature space by using local feature descriptors that analyze the geometric peculiarities in the neighborhood of the interest points were proposed. However, the resulting correspondences are noisy and contain a large number of outliers. This impairs the direct applicability of these approaches for deformation monitoring. In this work, we propose Feature to Feature Supervoxel-based Spatial Smoothing (F2S3), a new deformation analysis method for point cloud data. In F2S3 we extend the recently proposed feature-based algorithms with a neural network based outlier detection, capable of classifying the putative pointwise correspondences into inliers and outliers based on the local context extracted from the supervoxels. We demonstrate the proposed method on two data sets, including a real case data set of a landslide located in the Swiss Alps. We show that while the traditional approaches, in this case, greatly underestimate the magnitude of the displacements, our method can correctly estimate the true 3D displacement vectors.
