Growth strategy determines aspects of brain performance

The interplay between structure and function is crucial in determining some emerging properties of many natural systems. Here we use an adaptive neural network model inspired in observations of synaptic pruning that couples activity and topological dynamics and reproduces experimental temporal proﬁles of synaptic density, including an initial transient period of relatively high synaptic connectivity. Using a simpliﬁed framework, we prove that the existence of this transient is critical in providing ordered stationary states that have the property of being able to store stable memories. In fact, there is a discontinuous phase transition between the ordered memory phase and a disordered one as a function of the initial transient synaptic density. We also show that intermediate synaptic density values are optimal in order to obtain these stable memory states with a minimum energy consumption, and that ultimately it is the transient heterogeneity in the network what determines the stationary state. Our re-sults here could explain why the pruning curves observed in actual brain areas present their characteristic temporal proﬁles and, eventually, anomalies such as autism and schizophrenia associated, respectively, with a deﬁcit or an excess of pruning.
Mobile atmospheric measurements and local-scale inverse estimation of the location and rates of brief CH4 and CO2 releases from point sources

Abstract. We present a local-scale atmospheric inversion framework to estimate the location and rate of methane (CH4) and carbon dioxide (CO2) releases from point sources. It relies on mobile near-ground atmospheric CH4 and CO2 mole fraction measurements across the corresponding atmospheric plumes downwind the sources, on high-frequency meteorological measurements, and a Gaussian plume dispersion model. It exploits the spread of the positions of individual plume cross-sections and the integrals of the gas mole fractions above the background within these plume cross-sections to infer the position and rate of the releases. It has been developed and applied to provide estimates of brief controlled CH4 and CO2 point source releases during a one-week campaign in October 2018 at the TOTAL's experimental platform TADI in Lacq, France. These releases lasted typically 4 to 8 minutes and covered a wide range of rates (0.3 to 200 gCH4/s and 0.2 to 150 gCO2/s) to test the capability of atmospheric monitoring systems to react fast to emergency situations in industrial facilities. It also allowed testing their capability to provide precise emission estimates for the application of climate change mitigation strategies. However, the low and highly varying wind conditions during the releases added difficulties to the challenge of characterizing the atmospheric transport over the very short duration of the releases. We present our series of measurements of CH4 and CO2 mole fractions using instruments onboard a car that drives along the roads ~50 to 150 m downwind the 40 m × 60 m area of controlled releases for each of the releases and the results from the inversions of the release locations and rates. The comparisons of these results to the actual position and rate of the controlled release indicate a 20 %–30 % average error on the release rates and a ~30–40 m errors in the estimates of the release locations. These results are shown to be promising especially since better results could be expected for longer releases and under meteorological conditions more favorable to local scale dispersion modeling.
A FAST `1-TV ALGORITHM FOR IMAGE RESTORATION

Image restoration problems are often solved by (cid:28)nding the minimizer of a suitable objective function consisting of a data-(cid:28)tting term and a regularization term. In this paper, we consider the data-(cid:28)tting term measured in the (cid:96) 1 norm to handle non-Gaussian additive noise, and the regularization term given by the total variation to restore image edges. We propose a new objective function for this image restoration problem by making use of new variables to modify the data-(cid:28)tting term and the total variation regularization term. An alternating minimization algorithm based on the new objective function is employed to restore blurred and noisy images. Our experimental results show that the quality of restored images by the proposed method is competitive with those restored by the other tested methods. We also show the convergence of the alternating minimization algorithm and demonstrate that the proposed algorithm is very e(cid:30)cient.

Offline Verification of Signature Using CNN

— Now a day’s signature is becomes a most important biometric authentication technique. In banks or at the other necessary documents, signature plays an important role to authenticate the person. In this technique, we are going to present a deep learning approach for offline signature verification to prevent the fraud signatures by fake peoples. We are going to do deep learning with the help of Convolution Neural Network (CNN). In this study, we are going to collect dataset of different signatures from the different angles. Signature is taken as an input in the form of image. For signature recognition, it is important to make structural and some geometrical calculation getting to extract special features from the signatures then we train a man-made neural network on these features from different signers. Finally, the extracted features from the tested signature are compared with the previously trained features and that we know the signer.
Does the 'Intransitive Stage' Exist in Japanese-Speaking Children?: Acquisition of Morphologically-Related Transitive and Intransitive Verbs in Japanese 日本語母語児の自動詞への偏りの有無: 日本語の自動詞他動詞ペアの習得について

The verb in the above example, doite, is a request form of doku, a VI. The child wanted a chair to be moved, and the correct verb form is dokete, the transitive counterpart of the VI. Ito stated that, since children had not yet acquired VTs in this stage, they would use the intransitive counterparts instead. He called this the 'intransitive stage' and suggested that children use VIs only due to their cognitive developmental stage (i.e., the egocentric stage). In the second stage, they acquire the causative suffix -sase and use it with VIs in place of VTs. In the third stage, -sa in the causative suffix drops. Finally children acquire VTs and use them correctly. Ito argued that children were not able to produce VTs correctly until the last stage in his four-stage model. Nomura and Shirai (1997) examined longitudinal data from a Japanese-speaking child, Sumihare (1;04-2;04). Contra to Ito, they hypothesized that the child would use both VIs and VTs early, and that the overextension of VI to VT would be reflective of the distribution of input. In their data, however, Sumihare's verb production showed a bias toward VIs (75-100%) from the age of 1;05 to 1;07, supporting Ito's claim: the child's verbs are predominantly intransitive at an early stage. This tendency was more prominent in morphologically-related VI-VT pairs, such as kowareru [to break] and kowasu [to break something]. Sumihare only used the intransitive sides of the pairs up to 1;07. On the other hand, Sumihare's overextension of VIs to VTs was rare in comparison to the correct use of VI-VT pairs. Thus, Nomura and Shirai's study did not support Ito's fourstage model, though it supported the notion of the intransitive stage in the child's language development. In addition to Sumihare's data, they analyzed adults' speech addressed to him, and found that adults' use of VIs was higher than 70% in proportion up to 1;07 but 50-70% after 1;08, which approximates Sumihare's use of VIs. Nomura and Shirai suggested that Sumihare's frequent use of VIs at an early stage was a reflection of the input distribution patterns. 2019 CAJLE Annual Conference Proceedings
Optimization and Assessment of a hybrid Solar-Wind-Biomass Renewable Energy System for Kiribati Island

This paper presents a feasibility study of photovoltaic (PV), wind, biomass and battery storage based hybrid renewable energy system (HRES) providing electricity to residential area in Australia. The monthly daily mean global solar irradiance and wind speed data of the capitals of the seven regions of the six states and various territories of Australia (Queensland, Northern Territory, South Australia, Tasmania, Victoria, Western Australia and New South Wales) are generated by the RETScreen Clean Energy Project Analysis Software produced by Natural Resources Canada. The long term continuous implementation of the system is simulated. The software HOMER produced by the National Renewable Energy Laboratory is used as a simulating tool. Their cost and emissions are compared with each other among the systems. It is found that an off-grid PV-wind-biomass HRE system is an effective way of emissions reduction and it does not increase the investment of the energy system. An off-grid hybrid energy system has been designed as well as simulated to support a small community considering an average load demand of 165.29 kWh/d with a peak load of 24.57 kW. The simulation and optimization of operations of the system have been done by HOMER software using the real time field data of solar radiation, wind speed and biomass of that particular area. The simulation ensures that the system is economically and environmentally feasible with respect to net present cost (NPC) and CO2 emission limitations. The result shows that NPC and CO2 emission can be reduced about 31.65%; equivalent to 16 tons per year as compared to conventional power plants. The NPC of the optimized system has been found to be about USD 294,382.00, having the per unit Cost of Energy (COE) of USD 0.381/kWh. The analyzed hybrid energy system might be applicable for other regions of the world where there are similar climatic conditions.
The relation of catchment shape descriptors to lag time

Abstract One of the most important hydrological response characteristics is the lag time. It is well known as being under the influence of the morphometric properties of the basin, which could be expressed by catchment shape descriptors. In this paper, the geometric characteristics of an equivalent ellipse proposed by Moussa(2003) is applied for the lag time analysis. The lag time is obtained from the rainfall-runoff observed data by the method of moments suggested by Nash(1960) and the relationships between the basin morphometric properties and the lag time are discussed as applied to 3 catchments in Korea. Additionally, the shapes of equivalent ellipse are examined how they are transformed from upstream area to downstream one. As a result, the relationship between descriptors based on a equivalent ellipse,    and     , and the lag time is shown to be close and the shape of ellipse is presented to approach a circle along the river downwards. Also, the notion of compactness which is used to express the shape of an irregular plan-form is tried to apply.
Effects of several physical and chemical factors on eggs development of Neobenedenia melleni

Neobenedenia melleni(Menogenea:Capsalidae) is one of the most important pathogens of the marine net-cage culture fishes,it has a low host specificity and wide distribntion,and shucks on the gill and skin on fish,causing a high mortality among host fish.The adults lay hundreds of eggs that twin round the net or sundries in sea-water,it will be hatched 5～7 days later,and than attack on the fishes again.Large number of eggs collected and fell individually on culture vessels.The eggs were incubated at sea-water under different temperatures,different salinities and different pH values.The results showed that between 18~29℃,the higher the temperature,the faster the development of the eggs.Over 33℃ or under 18℃ the development stops.The development of the eggs was stopped under salinity of 13.7 and it stops at the stage of eyed-egg both salinities 22.9 or 44.3. The influence of pH was no so obvious.The eggs developed well and hatched at either pH 5.5 or pH 9.5,but the survive time and activity of the hatched ciliary larvas are obviously lowering when pH 6.0 or 9.0. It was shown that the egg's shell can be against the influence of changing pH.
Anyons and Topological Quantum Computation

The aim of this text is to provide an introduction to the theory of topological quantum computation. We give an introduction to the theory of anyons (two-dimensional quasi-particle excitations that have exotic statistics) and how we can use these to perform fault-tolerant quantum computation. Additionally, we give a complete description of an exactly solvable spin lattice model whose local low-energy excitations of the Hamiltonian behave as anyons. We conclude by indicating how this model can be generalized so as to perform universal quantum computation. ∗joaomroliveira@tecnico.ulisboa. pt 1
The Nitrogen Metabolized Character in Leaves of Transgenic Bt Cotton Nucotn 33B and Its Regulation

The trial indicated that nitrate-reductase (NR) activity in leaves showed descending trend itself during the florescence of transgenic cotton Nucotn 33B, the protease activity and protein content showed increasing trend itself, nitrogen and amino acid content had positive correlation with NR activity. The content of toxin protein showed a saddle shape variety trend from budding to flourishing. The leaves NR activity and protease activity have been improved by DPC (mepiquat chloride) treatment and the content of leaves protein, amino acid and the total nitrogen have been increased. At the same time the toxin protein content has been heightened. Finally the boll weight and boll number per plant have been increased.
Interference Mitigation for Synthetic Aperture Radar Data using Tensor Representation and Low-Rank Approximation

Radio frequency interference (RFI) is a critical issue to synthetic aperture radar (SAR), which would cause great distortions to amplitude and phase information of the received echoes. Most of the existing literatures deal with the interference separation problem in time domain, frequency domain, or time-frequency domain using the matrix representation and matrix optimization tools, without further exploiting the correlation among multiple dimensional measurements. This paper proposes an interference separation for SAR data using tensor representation by formulating a novel time-frequency azimuth tensor. Then, the low-rank property of the interference is utilized and the interference contribution is estimated using low rank tensor approximation. Experimental results demonstrate that the interference components is effectively extracted, and well imaging results could be recovered.
Air-Filled Substrate Integrated Waveguide (AFSIW) Filter with Asymmetric Frequency Response

A filter with asymmetric frequency response based on air-filled substrate integrated waveguide (AFSIW) is introduced. The proposed filter is low-loss, compact, and allows the introduction of a transmission zero in the upper-side. The transmission zero is implemented using the multilayer feature of the AFSIW technological platform as the secondary path of the signal is located in the bottom substrate of the structure, while the primary path is located in the inner substrate. Furthermore, the robustness of the structure against printed circuit board (PCB) standard processes highlights the high interest of the structure. For demonstration purposes, a third-order AFSIW filter with an asymmetric frequency response operating at 21 GHz with a fractional bandwidth of 1.53% is fabricated and measured. The measured results are in good accordance with the simulation results in and out band results. The fabricated prototype exhibits measured insertion loss of 0.66 dB with an unloaded Q-factor of 1429, which is excellent for a planar structure.
Positional Tracking With Time-of-Flight Depth Sensor and Webcam

In virtual reality systems, the primary form of input is often the user’s body positioning and gesture. The ﬁrst step to processing any of this input is to detect the position of the user in the scene. Integrating work on color-based marker detection and depth imaging, we present a system that uses a combination of an RGB we-bcam and a time-of-ﬂight depth camera to track markers based on color and shape. We then implemented a small painting demo to showcase these features, tracking the position of the head mounted display as well as a marker in the scene in order to allow users to draw 3D strokes in a virtual environment.
Technological and Organizational Absorption in the Development of the Modern Japanese Cotton Industry

It is well known that the cotton industry in modern Japan, which was made up of larger spinning companies, small-and medium-sized independent weavers in local producing centres (sanchi), merchants and trading companies among others, became an extremely powerful organization. In 1933, in terms of the volume of cotton cloth exports Japan surpassed the United Kingdom, which had dominated the world export markets since the Industrial Revolution (see Appendix 1). The first objective of this paper is to statistically demonstrate how important this industry was for the Japanese economy. Although there are some earlier attempts to grasp its magnitude, this paper makes the first attempt to elucidate the share of this industry in national income, particularly for the interwar period. The following two sections of the paper discuss the importance of absorption by large spinning companies of technology and organizations from advanced countries, especially from the United Kingdom and the United States of America. In particular, the paper addresses issues relating to the adoption of manufacturing technology of modern spinning in the late nineteenth century, mergers and acquisitions around 1900, and vertical integration in the 1900s and 1910s.
Changes in the Dielectric Properties of ex-vivo Ovine Kidney Before and After Microwave Thermal Ablation

In this work, a comparison in terms of dielectric properties (i.e. relative permittivity and conductivity) between ablated and non-ablated kidney samples (N = 3) was conducted. Measurements before and after ablation (N = 54) were performed on three different tissues (cortex, outer medulla, inner medulla) of ex-vivo ovine kidneys across the frequency range of 500 MHz – 8.5 GHz. Results show that both relative permittivity and conductivity decrease after ablation because of the decrease of the water content in the tissue. In particular, the highest difference between pre-ablation and post-ablation was observed in the tissue characterised by the highest water content.

INHOMOGENEOUS BARYOGENESIS MODEL AND ANTIMATTER IN THE UNIVERSE

Cosmic ray and gamma-ray data at present do not rule out antimatter domains in the Universe, separated at distances bigger than 20 Mpc from us. Hence, it is interesting to explore the possible generation of vast antimatter structures during the early Universe evolution. We discuss an inhomogeneous baryogenesis model, based on a SUSY baryogenesis scenario. We have accounted for the particle creation processes that play an essential role for the correct determination of the final value of the baryon asymmetry, generated in these baryogenesis scenarios. We have explored the dependence of the produced baryon asymmetry on the parameters of the model. It is shown that for a natural range of the parameters’ values this model is able to explain the value of the locally observed matter-antimatter asymmetry and also to predict antimatter domains, separated from the matter ones by baryonically empty voids.
Summary of a workshop on extreme weather events in a warming world organized by the Royal Swedish Academy of Sciences

Abstract Climate change is not only about changes in means of climatic variables such as temperature, precipitation and wind, but also their extreme values which are of critical importance to human society and ecosystems. To inspire the Swedish climate research community and to promote assessments of international research on past and future changes in extreme weather events against the global climate change background, the Earth Science Class of the Royal Swedish Academy of Sciences organized a workshop entitled ‘Extreme weather events in a warming world’ in 2019. This article summarizes and synthesizes the key points from the presentations and discussions of the workshop on changes in floods, droughts, heat waves, as well as on tropical cyclones and extratropical storms. In addition to reviewing past achievements in these research fields and identifying research gaps with a focus on Sweden, future challenges and opportunities for the Swedish climate research community are highlighted.
Feeding Flaxseed to Guinea Pigs (Cavia porcellus) Under Northern Peruvian Condition: II. Effects on Performance and Apparent Total Tract Nutrient Digestibility

A study was conducted to determine the effects of graded levels of flaxseed on performance and apparent total tract nutrient digestibility (ATTD) of guinea pigs. Ninety (45 males and 45 females) one-month weaned guinea pigs were blocked (5 males or 5 females/cage) by sex and body weight and randomly allotted to three dietary concentrates (15 g/animal) containing 0, 50 and 100 g/kg flaxseed with ad-libitum fresh alfalfa. Results showed that flaxseed inclusion had no influence on total feed intake body weight gain and feed conversion ratio (FCR). However, males had higher total feed intake (53.6 vs. 49.5 g/day, P = 0.004), body weight gain (11.9 vs. 10.5 g/day, P < 0.001) and therefore lower FCR (4.04 vs. 4.79, P = 0.006) than females. Flaxseed supplementation had also no effects on ATTD of dry matter, organic matter, neutral detergent and gross energy. Apparent total tract digestibility of dry matter, crude protein and gross energy were higher in female than male guinea pigs while ATTD of neutral detergent fiber were not influenced by sex. Apparent total tract digestibility of fatty acids was similar for all treatments and both sexes. It was concluded that under the current study conditions (i.e. ad-libitum fresh alfalfa + concentrate), flaxseed inclusion up to 100 g/kg of the concentrate had no effects on guinea performance and ATTD. However, male guinea pigs exhibited better performance but lower ATTD than females.
