description: We study analytically and numerically envelope solitons (bright and gap solitons) in a one-dimensional, nonlinear acoustic metamaterial, composed of an air-filled waveguide periodically loaded by clamped elastic plates. Based on the transmission line approach, we derive a nonlinear dynamical lattice model which, in the continuum approximation, leads to a nonlinear, dispersive and dissipative wave equation. Applying the multiple scales perturbation method, we derive an effective lossy nonlinear Schrödinger equation and obtain analytical expressions for bright and gap solitons. We also perform direct numerical simulations to study the dissipation-induced dynamics of the bright and gap solitons. Numerical and analytical results, relying on the analytical approximations and perturbation theory for solions, are found to be in good agreement.

description: The goal of this paper is to examine experimental progress in laser wakefield acceleration over the past decade (2004-2014), and to use trends in the data to understand some of the important physical processes. By examining a set of over 50 experiments, various trends concerning the relationship between plasma density, accelerator length, laser power and the final electron beam en- ergy are revealed. The data suggest that current experiments are limited by dephasing and that current experiments typically require some pulse evolution to reach the trapping threshold.

description: Nitrate (NO3−) is one of the most common contaminants of water bodies with harmful effects to aquatic life and human beings. There is a need for development of sorbents for effective removal of NO3− form aqueous streams. The aim of present study was to develop a Polyaniline modified halloysite nanoclay (PAni-HC) composite sorbent for the uptake of NO3− from aqueous medium. Aniline coated on halloysite clay was oxidised in acidic medium at 4ºC to synthesise PAni-HC composite in one pot reaction. Successful incorporation of polyaniline (PAni) in the clay matrix was confirmed by different surface characterisation techniques. The as synthesised PAni-HC composite sorbent was tested for NO3− sorption in a batch mode in the initial concentration range of 5–500 mg L−1. The analysis of NO3− was performed using ion chromatography in the suppressed conductivity mode. The experimental data were assessed using different kinetic and equilibrium models for understanding the sorption behaviour of the PAni-HC composite. Sorption followed pseudo second order kinetics and intraparticle diffusion model. The maximum Langmuir sorption capacity of PAni-HC composite for NO3− was found to be 27.9 mg g−1. The composite sorbent when treated with groundwater samples exhibited quantitative removal (> 90%) of NO3−thus demonstrating the applicability of the sorbent in real situations.
Periodically driven random quantum spin chains : Real-Space Renormalization for Floquet localized phases

description: When random quantum spin chains are submitted to some periodic Floquet driving, the eigenstates of the time-evolution operator over one period can be localized in real space. For the case of periodic quenches between two Hamiltonians (or periodic kicks), where the time-evolution operator over one period reduces to the product of two simple transfer matrices, we propose a Block-self-dual renormalization procedure to construct the localized eigenstates of the Floquet dynamics. We also discuss the corresponding Strong Disorder Renormalization procedure, that generalizes the RSRG-X procedure to construct the localized eigenstates of time-independent Hamiltonians.

description: We study nonlinear mixing effects among quadrupole modes and scissors modes in a harmonically trapped Bose-Einstein condensate. Using a perturbative technique in conjunction with a variational approach with a Gaussian trial wave function for the Gross-Pitaevskii equation, we find that mode mixing selectively occurs. Our perturbative approach is useful in gaining qualitative understanding of the recent experiment [Yamazaki et al., J. Phys. Soc. Japan 84, 44001 (2015)], exhibiting a beating phenomenon of the scissors mode as well as a modulation phenomenon of the low-lying quadrupole mode by the high-lying quadrupole mode frequency. Within the second-order treatment of the nonlinear mode coupling terms, our approach predicts all the spectral peaks obtained by the numerical simulation of the Gross-Pitaevskii equation.

description: Temporal and seasonal variations of groundwater arsenic concentration are very significant for the exploration of its mobilisation mechanisms and to frame the policies of viable usage of arsenic-contaminated groundwater. Much less is known about the temporal and seasonal pattern of variation of arsenic contamination in shallow groundwater from the present study area (Karimpur blocks, Nadia district, West Bengal, India). So, to extend the understanding, the present study encompasses the steady monitoring of 15 wells of shallow depth from the study area for the period of 2014–2016. It has been observed that geochemical components were varying extensively during the period and the same trends follow for both Fe and As. During the period, the groundwater levels oscillated seasonally which promotes the reductive dissolution of Fe-oxides and/or oxy-hydroxides (As bearing minerals) which is aided by less dispersion of atmospheric oxygen into the shallow aquifers maintaining the reducing environment in the aquifers. The supply of dissolved organic matter into shallow aquifers was also evident by variation of Cl− ion concentration which may help to enhance arsenic mobilisation into shallow groundwater. Moreover, groundwater recharge from both regional rivers and perennial sources influences the evolution of anoxic conditions in the areas with low aquifers permeability consisting mainly of clayey and/or silty intercalations. Likewise, irrigation practices have been augmented to understand its role in arsenic mobilisation.

description: Classical novae occur on the surface of an accreting white dwarf in a binary system. After ejection of a fraction of the envelope and when the expanding shell becomes optically thin to X-rays, a bright source of supersoft X-rays arises, powered by residual H burning on the surface of the white dwarf. While the general picture of the nova event is well established, the details and balance of accretion and ejection processes in classical novae are still full of unknowns. The long-term balance of accreted matter is of special interest for massive accreting white dwarfs, which may be promising supernova Ia progenitor candidates. V5116 Sgr was observed as a bright and variable supersoft X-ray source by XMM-Newton 610~days after outburst. The light curve showed a periodicity consistent with the orbital period. During one third of the orbit the luminosity was a factor of seven brighter than during the other two thirds of the orbital period. In the present work we aim to disentangle the X-ray spectral components of V5116 Sgr and their variability. We present the high resolution spectra obtained with XMM-Newton RGS and Chandra LETGS/HRC-S in March and August 2007. The grating spectrum during the periods of high-flux shows a typical hot white dwarf atmosphere dominated by absorption lines of N VI and N VII. During the low-flux periods, the spectrum is dominated by an atmosphere with the same temperature as during the high-flux period, but with several emission features superimposed. Some of the emission lines are well modeled with an optically thin plasma in collisional equilibrium, rich in C and N, which also explains some excess in the spectra of the high-flux period. No velocity shifts are observed in the absorption lines, with an upper limit set by the spectral resolution of 500 km/s, consistent with the expectation of a non-expanding atmosphere so late in the evolution of the post-nova.

Reading between the lines: linguistic properties as cues for word segmentation in Chinese sentence reading

description: A major feature that distinguishes Chinese writing from the alphabetic system is that words are not separated by spaces in Chinese sentences. It thus remains a puzzle how Chinese readers segment and identify words in sentences in order to read efficiently. The present study investigated whether and how Chinese readers use the morphological structure of words as a cue to guide their word segmentation and identification process. Two-character target words varying in morphological complexity (monomorphemic versus compound words) were embedded in sentences, and colour (Experiment 1) and word space (Experiment 2) manipulations were introduced to create a congruent or incongruent segmentation of the target words. Experiment 1 showed a slowdown to monomorphemic words when segmentation was incongruent, relative to the non-coloured control condition, providing some support for utilising morphological cues for word segmentation; however, the results of Experiment 2 were less clear.

description: A third-order three-dimensional symmetric traceless tensor, called the \emph{octupolar} tensor, has been introduced to study tetrahedratic nematic phases in liquid crystals. The octupolar \emph{potential}, a scalar-valued function generated on the unit sphere by that tensor, should ideally have four maxima capturing the most probable molecular orientations (on the vertices of a tetrahedron), but it was recently found to possess an equally generic variant with \emph{three} maxima instead of four. It was also shown that the irreducible admissible region for the octupolar tensor in a three-dimensional parameter space is bounded by a dome-shaped surface, beneath which is a \emph{separatrix} surface connecting the two generic octupolar states. The latter surface, which was obtained through numerical continuation, may be physically interpreted as marking a possible \emph{intra-octupolar} transition. In this paper, by using the resultant theory of algebraic geometry and the E-characteristic polynomial of spectral theory of tensors, we give a closed-form, algebraic expression for both the dome-shaped surface and the separatrix surface. This turns the envisaged intra-octupolar transition into a quantitative, possibly observable prediction. Some other properties of octupolar tensors are also studied.

description: Chromium occurs in a variety of oxidation states, including hexavalent chromium as a natural contamination of high toxic quality and portability. The release of chromium into the aqueous medium through effluents from industries such as tanneries, textiles, mining, painting, printing, photography and medicinal industries. Clean removal of chromium from the industrial wastewater treatment process is a challenge due to improper selection of technologies from economic, technical and environmental aspects. Adsorption is a very promising and efficient technology for the removal of hexavalent chromium from wastewater. Chitosan as the only polycation coming from renewable resources is endowed with intrinsic valuable properties, such as: biocompatibility, biodegradability, low cost, easy availability, and high reactivity due to plenty of the reactive functional groups (-NH2 and-OH). Due to its solubility in a slightly acidic environment, its ability as an adsorbent for wastewater treatment is hindered. The preparation of nanocomposites with organic and inorganic nanomaterials inhibits the solubility of chitosan in the acid media and could be used to remove Cr(VI) with high adsorption efficiency, non-toxicity, biodegradability and availability. This review outlines recent advances in polymer-grafted chitosan, magnetic chitosan, clay-chitosan, and carbon (multiwall carbon nanotube and graphene oxide)-chitosan nanocomposites and their use in removing toxic Cr (VI) from solution and wastewater. Special emphasis was given to their adsorption capacity, kinetics and adsorption isotherm of Cr (VI) removal. By analysing the various process mechanisms and variables, we appear to demonstrate that nanocomposites can overcome chitosan ‘s limitations as an adsorbent.

description: We consider the problem of binary prediction with expert advice in settings where experts have agency and seek to maximize their credibility. This paper makes three main contributions. First, it defines a model to reason formally about settings with selfish experts, and demonstrates that "incentive compatible" (IC) algorithms are closely related to the design of proper scoring rules. Designing a good IC algorithm is easy if the designer's loss function is quadratic, but for other loss functions, novel techniques are required. Second, we design IC algorithms with good performance guarantees for the absolute loss function. Third, we give a formal separation between the power of online prediction with selfish experts and online prediction with honest experts by proving lower bounds for both IC and non-IC algorithms. In particular, with selfish experts and the absolute loss function, there is no (randomized) algorithm for online prediction-IC or otherwise-with asymptotically vanishing regret.

Financing the green transition: evidence from climate regulations worldwide

description: I investigate the effects of climate laws on the capital structure of firms worldwide. My results indicate that in the aftermath of the introduction of climate legislations, firms tend to maintain higher leverage. This trend is particularly noticeable among firms with higher greenhouse gas (GHG) emissions, those with substantial exposure to climate risk opportunities, and those situated in countries characterized by a low Uncertainty Avoidance index, a high Individualism index, robust environmental law enforcement, and heightened public awareness of corporate social responsibility (CSR)issues. Furthermore, I find that companies with high GHG emissions are more inclined to tie executive compensation to environmental, social, and governance (ESG)performance following the enactment of climate-related legislations. Such compensation structures linked to ESG performance after the introduction of climate legislation enhance a firm’s investment in green R&D. These firms show a preference for debt financing to support their green initiatives. Lastly, I find that climate laws reduce the debt maturity, profitability, and value of companies.

description: Combination of counter current salting-out homogenous liquid–liquid extraction and deep eutectic solvent–based hollow fibre protected preconcentration method has been developed for the extraction of some antibiotics from propolis samples prior to their determination by ion mobility spectrometry. In this method, an appropriate amount of the powdered propolis is mixed with iso-propanol and deionised water to obtain a homogenous solution. Then, this solution is passed through a glass tube filled with sodium chloride. By this action, the fine droplets of iso-propanol are released and the analytes are extracted into them. The separated iso-propanol is taken and slowly entered into a hollow fibre. By doing so, the analytes are trapped in the pores of hollow fibre and the organic solvent is evaporated after a few minutes. After that, a few microlitres of a water-miscible deep eutectic solvent (prepared from N,N–dimethyl ammonium chloride and propionic acid) is added to elute the analytes from the pores of hollow fibre. Method validation studies indicated that the introduced method has low limits of detection (0.27–0.41 ng g–1) and quantification (0.91–1.37 ng g–1), high enrichment factors (562 –603) and extraction recoveries (84–90%), acceptable repeatability (relative standard deviation ≤ 9.2%) under the optimum conditions.

description: We study the magnetohydrodynamics of relativistic plasmas accounting for the chiral magnetic effect (CME). To take into account the evolution of the plasma velocity, obeying the Navier-Stokes equation, we approximate it by the Lorentz force accompanied by the phenomenological drag time parameter. On the basis of this ansatz, we obtain the contributions of both the turbulence effects, resulting from the dynamo term, and the magnetic field instability, caused by the CME, to the evolution of the magnetic field governed by the modified Faraday equation. In this way, we explore the evolution of the magnetic field energy and the magnetic helicity density spectra in the early Universe plasma. We find that the right-left electron asymmetry is enhanced by the turbulent plasma motion in a strong seed magnetic field compared to the pure the CME case studied earlier for the hot Universe plasma in the same broken phase.

Direct solar air heating inside small-scale linear Fresnel collector assisted by a turbocharger experimental characterization
Creators: name: Famiglietti, Antonio

Publisher: name: Zenodo
Year: 2021

description: In recent years many efforts are being made to replace fossil fuel with renewable energy sources in the industry, both for electricity and heat production. Several high-energy demanding processes use hot air as heat and moisture carrier in the low and medium temperature range, for which solar air heaters offer great potential. Among solar energy technologies, Linear Fresnel collectors can provide heat in the medium temperature range at a decreasing cost. Direct air heating inside Linear Fresnel collector avoids the use of a liquid heat transfer fluid and the heat exchanger, reducing installation and maintenance costs, as well as residues. In this innovative technology, an automotive turbocharger reduces auxiliary energy consumption for air pumping through the solar collector, which would be unsustainable at medium and large scale. It configures an original open-to-atmosphere Brayton cycle with null power efficiency. In this study, an experimental investigation is carried out on the first small-scale prototype solar field of 79.2 m2 area. It allows characterizing the thermal and mechanical behavior of the turbocharger, besides tuning and validating the numerical model implemented. Especial attention is given to the diabatic behavior of both turbomachines and to establish the limiting efficiency of the turbocharger as forefront research.

description: We introduce the Hydrangea simulations, a suite of 24 cosmological hydrodynamic zoom-in simulations of massive galaxy clusters (M_200c = 10^14-10^15 M_Sun) with baryon particle masses of ~10^6 M_Sun. Designed to study the impact of the cluster environment on galaxy formation, they are a key part of the `Cluster-EAGLE' project (Barnes et al. 2017). They use a galaxy formation model developed for the EAGLE project, which has been shown to yield both realistic field galaxies and hot gas fractions of galaxy groups consistent with observations. The total stellar mass content of the simulated clusters agrees with observations, but central cluster galaxies are too massive, by up to 0.6 dex. Passive satellite fractions are higher than in the field, and at stellar masses Mstar > 10^10 M_Sun this environmental effect is quantitatively consistent with observations. The predicted satellite stellar mass function matches data from local cluster surveys. Normalized to total mass, there are fewer low-mass (Mstar < 10^10 M_Sun) galaxies within the virial radius of clusters than in the field, primarily due to star formation quenching. Conversely, the simulations predict an overabundance of massive galaxies in clusters compared to the field that persists to their far outskirts (> 5r_200c). This is caused by a significantly increased stellar mass fraction of (sub-)haloes in the cluster environment, by up to ~0.3 dex even well beyond r_200c. Haloes near clusters are also more concentrated than equally massive field haloes, but these two effects are largely uncorrelated.

description: The aim of this paper is to analyse emerging trends in the fashion industry, focusing on the growing role the circular economy is playing in introducing a new business paradigm based on the so-called “3 Rs” principle: reduce, reuse and recycle. Six interesting cases studies are presented; three focus on fashion companies (Rifò, Rapanui and Cingomma) that base their business model on this circular economy principle, while the other three relate to companies (Orange Fiber, Ananas Anam, Due di Latte) using sustainable materials to produce fashion items. The careful selection of raw materials and the application of technological innovation in the production system allow companies to implement new sustainable approaches to production, resulting in two critical outcomes: recycled fashion products that can be reintegrated into the environment and the reuse of products that can be revalued without rather than wasted.

description: We show that in the presence of a three-dimensional (Weyl) spin-orbit coupling, a transverse spin current is generated in response to either a constant spin-independent force or a time-dependent Zeeman field in an arbitrary direction. This effect is the non-Abelian counterpart of the universal intrinsic spin Hall effect characteristic to the two-dimensional Rashba spin-orbit coupling. We quantify the strength of such an omnidirectional spin Hall effect by calculating the corresponding conductivity for fermions and non-condensed bosons. The absence of any kind of disorder in ultracold-atom systems makes the observation of this effect viable.

description: Topological phases of matter are often characterized by interface states, which were already known to occur at the boundary of a band-inverted junction in semiconductor heterostructures. In IV-VI compounds such interface states are properly described by a two-band model, predicting the appearance of a Dirac cone in single junctions. We study the quantum-confined Stark effect of interface states due to an electric field perpendicular to a band-inverted junction. We find a closed expression to obtain the interface dispersion relation at any field strength and show that the Dirac cone widens under an applied bias. Thus, the Fermi velocity can be substantially lowered even at moderate fields, paving the way for tunable band-engineered devices based on band-inverted junctions.

description: Acid treated locally available Bijoypur white clay was exfoliated with dodecyl amine to facilitate in-situ polymerisation of acrylic acid (AA) using N, N′‐methylenebisacrylamide (MBA) crosslinker and ammonium persulphate as the initiator for the preparation of a novel adsorbent. In order to obtain poly(acrylic acid)-graft-modified clay composite (PAA-g-MC), the growing PAA chain was ‘grafted onto’ the modified clay surface. The structural properties of the composite adsorbent were studied by X-ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FT-IR), X-ray fluorescence (XRF), and scanning electron microscope (SEM). Thermal properties of the composites were measured by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). The effect of different process parameters such as pH of dye solution, contact time, initial concentration of dye, and adsorbent amount on the removal efficiency of methylene blue (MB) from aqueous solution was evaluated by batch experiments. Characteristics data from XRD and XRF for raw clay and acid-treated clay showed that Bijoypur clay is rich in kaolinite, which contains a significant amount of quartz. However, treatment with HCl reduces 55% of quartz and increases the percentage of kaolinite that made it suitable for adsorbent used. Adsorption results showed that PAA-g-MC composite showed a maximum adsorption of 162.3 mg g−1 of 100 mg L−1 MB dye solution at pH 7.25 after 80 min of adsorption using 0.03 g L−1 of the adsorbent. Langmuir and Freundlich adsorption isotherms were studied and the equilibrium adsorption data were found to be well fitted with the Langmuir adsorption isotherm. The interaction between adsorbent and MB molecules was explained by chemisorption, as suggested by the pseudo-second-order kinetic model. Maximum monolayer adsorption of 168.4 mg g−1 was calculated from the Langmuir adsorption isotherm which is very close to the experimental value of 162.3 mg g−1.

description: This study explores the development of circular supplier selection criteria within the context of sustainable supply chain management. Recognizing the growing importance of circular economy principles in supply chain operations, the research aims to identify and validate key criteria for selecting suppliers who align with circular economy objectives. Utilizing a mixed-methods approach, the study first conducts a comprehensive literature review to establish a theoretical foundation. It then employs case study analysis and expert interviews to empirically refine and validate the proposed criteria. The findings reveal a set of critical factors including environmental, economic, and social dimensions, essential for circular supplier selection. These criteria are instrumental in guiding organizations towards sustainable and circular supply chain practices, fostering long-term environmental sustainability and economic resilience. The study concludes with implications for supply chain management and recommendations for future research in this evolving field.

description: We compute the boundary state corresponding to a fractional D$p$-brane with transverse motion and internal background fields: Kalb-Ramond and a $U(1)$ gauge field. The spacetime has the orbifold structure $\mathbb{R}^{1,5} \times\mathbb{C}^{2}/\mathbb{Z}_{2}$. The calculations are in the superstring theory. Using this boundary state we shall obtain the interaction amplitude between two parallel moving fractional D$p$-branes. We shall extract behavior of the interaction amplitude for large distances of the branes.

description: The US Green New Deal (GND) is a proposal calling for political action to tackle climate change. Its aim is to adopt policies that support the achievement of carbon-neutral, however, it has encountered significant obstacles in being passed as legislation. Some of this resistance is based on concerns relating to the potential consequences of climate actions on asset values. Utilizing the approach of Barraclough et al. (2013), we use option prices of fossil fuel firms to estimate the probability of the successful passage of the GND through four voting events related to the three versions of the proposal, namely the initial GND proposal in 2019, the Build Back Better Act (BBBA) in 2021, and the Inflation Reduction Act (IRA) in 2022. We find that the passing rates for the four voting events are 46.74%, 49.84%, 48.89%, and 41.16% respectively. We also estimate the proposals’ value effect and news effect on fossil firms. Specifically, we find the average value effect of GND, BBBA, IRA (Senate), and IRA (House) is negatively significant at –17.87% (–1.83 billion USD), –5.10% (551.81 million USD), –15.08% (–2.73 billion USD), and –11.66% (–2.65 billion USD) respectively. The average news effects for GND, BBBA, IRA(Senate), and IRA(House) have an average value of 6.28% (533.48 million USD), 2.27% (254.43 million USD), 7.13% (1.31 billion USD), and 5.23% (1.15 billion USD) respectively. Furthermore, we find that the value effects of the proposal are more pronounced for fossil fuel firms with higher carbon emissions.

description: Poor quality graduates and poor work adjustment among the work force are some contemporary challenges of higher education training in many societies. Affected graduates usually lack the technical skills, attitudes and competencies required to perform effectively when employed. Often times, difficulties to cope with the demands and expectations of the work environment put some at risk of job loss and redundancy; hence, undermining the achievement of the United Nations Sustainable Development Goals (UN SDG:4). Poor quality graduate outputs have been blamed on diverse factors which include: personal, institutional and socio-cultural. However, this study is focused on the institutional factors. The position of this paper is that institutional inputs which cover training have to be more strategic and progressive for the production of high skilled workforce that are competitive both locally and globally. This will enhance the achievement of UN SDG: 4, which is targeted at enhancing learning for the acquisition of vocational and technical skills for decent work as well as for global citizenship in a global world. Based on the aim of addressing learning gaps among graduates, this paper stresses the need for instructional inputs to be in tandem with global best practices, while adapting indigenous resources (value system) to impart learners, cognitively and affectively. The paper recommends that higher education institutions should leverage the training strategies pointed out in this paper to enhance quality of graduates and future labor force that can contribute to sustainable national development.

description: Drug abuse has become a global health problem over the past few years. Opioid abuse increased with an increase in the prescription of opioids for pain management. Many other classes of drugs are also abused and misused like anti-depressants, stimulants, hallucinogens, anti-psychotic, and anticholinergic drugs. One of the major reason is that patients falsely diagnosed with depression, anxiety, and severe pain are prescribed these drugs, which are likely to be addictive. Abuse-deterrent formulations are one means to control drug abuse and overdose of prescription opioids. In this review, we explained how abuse-deterrent technology works, key ingredients used in abuse-deterrent formulations, a brief about marketed opioid drug products with abuse-deterrent properties, and the stand of regulatory agencies in the approval process of opioid drug products. In the end, it summarized that pharmaceutical industries and the FDA put their efforts into reducing drug abuse by encouraging development of ADFs. Most available drug product having abuse-deterrent features contains Polyethylene oxide, which degrades at high temperature. It requires attention of researcher to find an alternate ingredient or process to overcome said problem. From a regulatory point of view, only a few regulatory agencies have published their guidance on ADFs. It is important to convey other regulatory organizations’ perspectives on ADFs as well.

description: The challenge of anomaly detection is to obtain an accurate understanding of expected behaviour which is intensified when the data are distributed heterogeneously. Transmitting raw data to a central site incurs high communication overhead and raises privacy issues. The concept of Edge AI allows computation to be performed at the edge site allowing for quick decision making in mission critical scenarios such as self-driving cars. A model is learnt locally and its parameters are transmitted and aggregated. However, existing methods of aggregation do not account for variance and heterogeneous distribution of data. They also do not consider edge constraints such as limited computational, memory and communication capabilities of edge devices. In this work, a fully Bayesian approach is employed by means of a Bayesian Random Vector Functional Link AutoEncoder being incorporated with Expectation Propagation for distributed training. Our anomaly detection system operates without any transmission of raw data, is robust under inhomogeneous network densities and under uneven and biased data distributions. It allows for asynchronous updates to converge in a few iterations and is a relatively simple neural network addressing edge constraints without compromising on performance as compared to existing more complex models.
