Abstract
Two nonlinear processes, namely, two-photon absorption (TPA) and stimulated Raman scattering (SRS) in Na2W2O7 crystal at a wavelength of 523.5 nm, are studied theoretically and experimentally depending on the polarization of the incident picosecond laser radiation. It was found that, due to the anisotropy of the band gap structure, the TPA coefficient at 523.5 nm strongly depends on the pump radiation polarization. For radiation along the c axis with polarization parallel to the a axis, the TPA coefficient was measured to be 1.28 cm GW−1, and no SRS process was registered. However, for polarization parallel to the b axis, no measurable TPA was detected and SRS with a gain of 6.5 cm GW−1 was observed. To the best of our knowledge, this is the first demonstration of the competition of two nonlinear processes in one crystal depending on its orientation.

Abstract

Objective. Motor decoding is crucial to translate the neural activity for brain-computer interfaces (BCIs) and provides information on how motor states are encoded in the brain. Deep neural networks (DNNs) are emerging as promising neural decoders. Nevertheless, it is still unclear how different DNNs perform in different motor decoding problems and scenarios, and which network could be a good candidate for invasive BCIs. Approach. Fully-connected, convolutional, and recurrent neural networks (FCNNs, CNNs, RNNs) were designed and applied to decode motor states from neurons recorded from V6A area in the posterior parietal cortex (PPC) of macaques. Three motor tasks were considered, involving reaching and reach-to-grasping (the latter under two illumination conditions). DNNs decoded nine reaching endpoints in 3D space or five grip types using a sliding window approach within the trial course. To evaluate decoders simulating a broad variety of scenarios, the performance was also analyzed while artificially reducing the number of recorded neurons and trials, and while performing transfer learning from one task to another. Finally, the accuracy time course was used to analyze V6A motor encoding. Main results. DNNs outperformed a classic Naïve Bayes classifier, and CNNs additionally outperformed XGBoost and Support Vector Machine classifiers across the motor decoding problems. CNNs resulted the top-performing DNNs when using less neurons and trials, and task-to-task transfer learning improved performance especially in the low data regime. Lastly, V6A neurons encoded reaching and reach-to-grasping properties even from action planning, with the encoding of grip properties occurring later, closer to movement execution, and appearing weaker in darkness. Significance. Results suggest that CNNs are effective candidates to realize neural decoders for invasive BCIs in humans from PPC recordings also reducing BCI calibration times (transfer learning), and that a CNN-based data-driven analysis may provide insights about the encoding properties and the functional roles of brain regions.

Abstract
With the progress in modern high-energy physics, the Standard Model is constantly being refined. As the last brick of the Standard Model, the Higgs boson was confirmed to be discovered in the Large Hadron Collider (LHC) in 2012. For the further exploration of the Higgs boson, the Circular Electron Positron Collider (CEPC) is proposed. The baseline detector concept of CEPC is guided by the particle flow principle. The Particle Flow Algorithm (PFA) reconstructs a list of low-level particles and associates every detector hit with these particles. The high granularity hadronic calorimeter (HCAL) represents an essential component of PFA-based detectors. This paper mainly presents the single-layer electronics design and development for the scintillator analog hadronic calorimeter prototype (AHCAL). The single-layer readout electronics consists of front-end electronics board (FEB) and data interface (DIF) board. The FEB carries the silicon photomultipliers (SiPM), plastic scintillators, and the SiPM signal readout circuit. A single SiPM coupled with a scintillator constitute the basic detection unit. The size of scintillator used here is 4 cm×4 cm. A sensitive area of 72×72 cm2 can be covered by the design presented here. 324 SiPMs coupled with scintillators are mounted on each FEB. Besides the huge sensitive area, The AHCAL prototype must also meet strict requirements on the integration and robustness of the electronics. This paper develops a complete single-layer readout electronics design that meets the requirements for use in the AHCAL. The results of beam test shows that the peak of the minimum ionizing particle (MIP) is separated from the pedestal evidently and the signal-to-noise ratio (SNR) is better than 20. The volume required for the electronics is less than 4 cm3 per channel. In addition, the FEB is sufficiently robust to avoid damage during intercontinental transportation. The development of the single-layer electronics represents significant progress in the design of a prototype device that meets the requirement for use in the CEPC.
Hamiltonian facets of classical gauge theories on E-manifolds
Authors: Mir Pau , Miranda Eva , Nicolás Pablo 
Published: May 2023

AbstractManifolds with boundary, with corners,b-manifolds and foliations model configuration spaces for particles moving under constraints and can be described asE-manifolds.E-manifolds were introduced in Nest and Tsygan (2001Asian J. Math.5599–635) and investigated in depth in Miranda and Scott (2021Rev. Mat. Iberoam.371207–24). In this article we explore their physical facets by extending gauge theories to theE-category. Singularities in the configuration space of a classical particle can be described in several new scenarios unveiling their Hamiltonian aspects on anE-symplectic manifold. Following the scheme inaugurated in Weinstein (1978Lett. Math. Phys.2417–20), we show the existence of a universal model for a particle interacting with anE-gauge field. In addition, we generalise the description of phase spaces in Yang–Mills theory as Poisson manifolds and their minimal coupling procedure, as shown in Montgomery (1986PhD ThesisUniversity of California, Berkeley), for base manifolds endowed with anE-structure. In particular, the reduction at coadjoint orbits and the shifting trick are extended to this framework. We show that Wong’s equations, which describe the interaction of a particle with a Yang–Mills field, become Hamiltonian in theE-setting. We formulate the electromagnetic gauge in a Minkowski space relating it to the proper time foliation and we see that our main theorem describes the minimal coupling in physical models such as the compactified black hole.
Improving classical capacity of qubit dynamical maps through stationary state manipulation
Authors: Siudzińska Katarzyna 
Published: May 2023

Abstract
We analyze the evolution of Holevo and entanglement-assisted classical capacities for two classes of phase-covariant channels. In particular, we show that these capacities can be improved by changing the stationary state of the channel, which is closely related to its non-unitality degree. The more non-unital the channel, the greater its capacity. The channel parameters are engineered through mixtures on the level of dynamical maps, time-local generators, and memory kernels, for which we propose construction methods. For highly non-unital maps, we achieve a temporary increase in the classical capacity that exceeds the entanglement-assisted classical capacity of the unital map. This shows that non-unitality can become a better quantum resource for information transition purposes than quantum entanglement.
Accuracy of Computer Vision Hough Line Transform for Water Level Measurement
Authors: Owen R , Wijaya V , Wardhana A W , Asy’ari M Z , Suharjanto G 
Published: May 2023

Abstract
Floods are natural disasters that often occur in countries with high rainfall, such as Indonesia. Floods occur due to sudden changes in water level; therefore, the dam cannot withstand the increase in water causing water to overflow into the riverbank area. As a result of this issue, a system was created that can be used to provide information about river water levels. This system relies on computer vision to program the camera to monitor the water level through image processing. Image processing allows the camera to process the image of the water surface detected at the ditch’s edge. The edge detection result is used as a water level detector using the Hough line transform, which generates a line to indicate the water level. The height detected by image processing differs from the actual height on the detected surface. The minimum and maximum error reading for both methods recorded in this experiment is 0,8 % and 16,67 %, respectively

Abstract
The problem of waste in urban areas that are not managed properly has created a threat to the environment and human life. And this problem is the co-responsibility of the community to get involved in waste management and waste recycling. It is necessary to sort the waste starting at home with recycling because the amount of waste going to the landfill can be reduced. Another benefit of sorting waste is reducing the risk of contaminating the environment. The 3R concept, that is, reuse, reduce, and recycle, has become a government regulation to improve the environmental and waste problems in Indonesia. The focus of this research is on households, beginning with the selection of household waste. Waste sorting is divided into 4 categories, namely organic waste, non-organic waste, B3 or e-waste, and sanitary waste. Using mobile app technology as a solution to encourage individual households, especially housewives, to participate in household waste sorting, the ‘Pilahin’ prototype app was introduced. The selection of media apps on smartphones is because the app has been widely used by urban communities. The app is packed with features that help users scan and detect trash and provide trash categories to identify and sort, as well as the option to find nearby trash banks. The app ‘Pilahin’ has over 40 design screens that have been turned into interactive prototypes and tested on 4 target users with satisfactory results. This application has the potential for development by working with organizations that are already working on waste classification.
The Field application efficiency Assessment of Paddy Field in Aceh Irrigation Scheme, Aceh, Indonesia

Published: May 2023

Abstract
The efficiency of project irrigation is the main factor in measuring the irrigation system’s effectiveness in conveying and distributing the water to a paddy field. The efficiency of irrigation projects in Aceh adopted from Indonesian irrigation standards is 65% which is much higher than generally used in some countries in Asia, i.e., 35-46%. This high value is caused by neglecting water losses in the paddy field when determining the project’s irrigation efficiency. This results in insufficient water for the overall irrigable areas planned in the irrigation scheme in Aceh. The study is aimed to assess the field application efficiency by investigating the water losses in paddy fields. To conduct the research, the paddy field in Pandrah Irrigation Project is plotted specifically. A drum technique instrument was installed in the plot to measure the evapotranspiration, percolation, and effective rainfall based on water balance analysis in the drum in one paddy growing season. The results showed that the field application efficiency is 75.34%. meaning some of the water supply could not be effectively consumed by the paddy. Based on the investigation, most water losses in paddy fields are caused by preferential flow through macropores in vicinity bunds which were triggered by the movement of rats, paddy roots, and bad plow of the field. Therefore, it is recommended to investigate the water losses that will occur due to the above assumption by continuing research in the future, so the project efficiency might be stated accurately when planning irrigation projects in Aceh.

Published: May 2023

AbstractIn a developing country like Indonesia, waste management remains one of the main problems faced due to a lack of coordination between various stakeholders and budget limitations to implement advanced waste management methods. The Batang regency is no exception, where overall waste reduction and waste recycling percentage (out of total generated waste) are only 0.61% and 0.08% respectively. One of its villages, Kalisalak village, is a religious agritourism village that has a lot of economic potential in various sectors, with by-products that can be utilized and processed as various materials and resources to improve the local community and support sustainable development. Organic waste from Kalisalak village can be processed into organic fertilizers, eco-enzymes, takakura basket, and biopore infiltration hole, while plastic waste can be used as paving block materials. Non-domestic sawdust waste from non-domestic sectors can be processed into growing media for ornamental plants, horticulture, and edible mushrooms. Thorough field surveys are still needed for this study. urveys are still needed for this study.
Green Waste, Waste Management Concept in Urban Areas, Study Case Agung Podomoro Land Tanjung Duren
Authors: Wangidjaja W. 
Published: May 2023

Abstract
Waste is part of human life. Garbage is a waste object / substance that is no longer used. The litter should receive serious attention and handling. However, due to the lack of understanding of the people and the government, as well as the lack of costs and incomes of most people, this waste problem has become neglected. Currently, most people have known the adverse effects of waste, including causing floods, diseases and odors that can interfere with life, but this is not balanced by the behavior of their own people. The purpose of this study is to try to find a way out of environmental sanitation problems, especially waste management in some companies.

Published: May 2023

Abstract
This study uses the finite element method to determine the value of deformation and Pullout Capacity on the Bored Pile. The results compared the calculation of the value of the deformation and Pullout Capacity on the Bored Pile with the finite element method with the pullout test results. The research method used finite element modeling and manual calculations. The results achieved in this study are that Soft Soil & Hard Soil modeling 6.47 mm for deformation and 267.495 tons for Pullout Capacity is closer to the actual value and MC Modelling is 9.08 mm for deformation and 268.497 tons for Pullout Capacity, which is the farthest modeling the actual value with a difference of approximately 50%. This is due to differences in correlation and actual soil type conditions between modeling and field conditions, because the finite element method modeling is assumed to be a perfect pile.
Barrier of Green Building Implementation in Construction Projects in Indonesia
Authors: Susanto James Widjaja , Sujana Caroline Maretha 
Published: May 2023

Abstract
The development of a city that including infrastructure support has a massive impact on environmental conditions and climate change. Green buildings are the key solution to environmental problems. However, the implementation of the green buildings are very slow in Indonesia. Most of dominant inhibiting factors for green building implementation are the difficulty of obtaining green materials, a lack of understanding of the importance of green buildings, the additional costs required to build green buildings, and the lack of support from the government. This research is conducted to sort out the factors inhibiting the construction/implementation of green buildings from the angle of contractors and owners. Many questionnaires have been distributed in cities in Indonesia then found that the factors that hindered contractors were lack of research on green building, lack of demand from owners, lack of strict regulation from the government, failures in planning, and longer project duration. From the owner’s side, what is anchoring is the lack of attention and interest, limited research on green building technology, high costs, and lack of cooperation between parties that support the owner delivering a green building.
Analysis of sheet pile position influence in countermeasure to landslide at the cutting slope in infrastructure project
Authors: Tantrio Anderson , Suhendra Andryan 
Published: May 2023

Abstract
Slope is a land surface that has a certain angle of inclination in the horizontal plane. The existence of the slope of the land causes the forces that push so that the soil at a higher elevation to move. If the movement is not resisted, the slope may collapse. The purpose of this analysis is to determine the effect of sheet piles where the position and depth of sheet piles, ground water level and earthquake factors on the stability of excavation slopes in infrastructure project of Karawang New Industry City (KNIC) LG area. For this reason, slope stability analysis was carried out using a finite element-based analysis program where the output sought was sheet pile displacement and safety factor. The data used in this study are N-SPT data and W-325 sheet pile property data. The sheet pile position is varied into 6 variations, at positions 2, 4, 6, 8, 10, and 12. The sheet pile length is varied from 4 meters to 12 meters and the slope water level is varied into 6 conditions, namely conditions without ground water, ground water level 5 meters, 4 meters, 3 meters, 2 meters and 1 meter. From this analysis it was found that the position of sheet pile affects the value of the safety factor and the critical depth of sheet piles. The analysis is continued by analyzing the earthquake load at a water level of 1 meter. From this analysis, all positions and depths are not able to withstand earthquake loads, so other alternatives are needed. Considering the earthquake load and the resulting landslide pattern, the slopes require additional reinforcement where sheet piles will be installed in position 10 with a length of 12 meters and at 1 meter from the roadside at a depth of 1 meter with a length of 11 meters. With this reinforcement, the safety factor value is 1.675 in static conditions and 1.131 in earthquake conditions so that sheet piles can meet the minimum limit requirements i.e., 1.5 in static conditions and 1.0 in earthquake conditions.
Corner Effects of Retaining Wall on Lateral Stress Distribution and Deformation
Authors: Kosalim Valdy , Gunawan Anthony 
Published: May 2023

Abstract
Retaining wall is commonly analysed in two-dimension (2D). This assumes that the wall is in plane strain conditions. While for most cases this assumption is applicable, the same cannot be applied to corners of retaining wall. This study aims to study the corner effects of retaining wall by modelling it in three-dimensional finite element software, PLAXIS 3D. The meeting point of two retaining wall is varied from 45° to 315° at 45° interval. Another parameter studied is the wall height, which is varied from 3 m to 9 m in 2 m intervals. The analysis shows that 45° and 90° walls have the lowest earth pressure and wall displacement. This is due to arching effects which is not present for walls with meeting point 135° and larger. As for displacement, the largest displacement is from 180° wall. This is because the movement of 180° wall is not restrained by the boundary conditions. For walls of other geometries, boundary conditions of the finite element model restrict the movement of walls in horizontal and/or vertical directions. Other factors include larger base geometries for non-180° wall, as well as distribution of disturbing force and resisting force.

Unmanned Aerial Vehicle (UAV) equipped with photogrammetry has a significant impact on sustainability. Despite the advances in construction equipment and management techniques to control the complexity and dynamic nature of toll road projects, the documentation of changes which occur on site remains a prevalent issue. This research is concerned in the visualization techniques for progress monitoring that illustrates progress deviations through superimposition of four-dimensional as-planned model on surface models. The results from the digital survey into BIM Authoring Tools followed by the identification of BIM elements through surface modelling. The analysis is conducted using the parameter of the volume of land cuts and fills to quantify deviations. The data retrieved from UAV drones enriched with geospatial parameters proved to provide reliable construction records, allowing greater control of construction progress. The proposed methodology may ultimately allow project participants to adjust schedule and allocate resources in a more precise manner.
