Correlation Based Imaging for Rotating Satellites

We consider imaging of fast moving small objects in space, such as low earth orbit satellites, which are also rotating around a fixed axis. The imaging system consists of ground based, asynchronous sources of radiation and several passive receivers above the dense atmosphere. We use the cross-correlation of the received signals to reduce distortions from ambient medium fluctuations. Imaging with correlations also has the advantage of not requiring any knowledge about the probing pulse and depends weakly on the emitter positions. We account for the target's orbital velocity by introducing the necessary Doppler compensation. To image a fast rotating object we also need to compensate for the rotation. We show that the rotation parameters can be extracted directly from the auto-correlation of the data before the formation of the image. We then investigate and analyze an imaging method that relies on backpropagating the cross-correlation data structure to two points rather than one, thus forming an interference matrix. The proposed imaging method consists of estimating the reflectivity as the top eigenvector of the migrated cross-correlation data interference matrix. We call this the rank-1 image and show that it provides superior image resolution compared to the usual single-point migration scheme for fast moving and rotating objects. Moreover, we observe a significant improvement in resolution due to the rotation leading to a diffraction limited resolution. We carry out a theoretical analysis that illustrates the role of the two point migration method as well as that of the inverse aperture and rotation in improving resolution. Extensive numerical simulations support the theoretical results.
Attentional bias for food cues after sleeve gastrectomy : a behavioral and electrophysiological study

Obesity has become a global health problem, and evidence suggests that there are important factors promoting overeating behaviour and obesity. This project is mostly based on the "food addiction" hypothesis, which emphasizes the similarities between drug use disorder and obesity. The consumption of high-calorie food, affects the dopaminergic pathway signalling, generating a pathologic response to food-related stimuli, which is the neuropathological basis for the attentional bias for food cues. Attentional bias for food cues could be related to food craving and the inability to lose weight, or a higher probability of weight regain. The attentional bias towards food stimuli was initially described in patients with eating disorders (ie anorexia nervosa, bulimia nervosa and binge eating disorders). In the last decade, the presence of this bias in patients with obesity has been explored. However, despite the fact that most of the studies support the presence of this bias in patients with obesity, this has been done with very different methodologies, the relevance as a prognostic factor has not been explored in-depth, neither the factors or intervention that could modify this bias in the long term follow-up. For this study, we selected a group of patients after at least 1 year from sleeve gastrectomy. Our objective was to evaluate the presence of attentional bias towards food and compare it with a control group. To assess the bias for food cues, we generated two tasks: food-modified Stroop task and visual task. The first one with electroencephalographic recording and the second one with eye-tracking recording. The electroencephalographic signal was processed to perform an event-related potentials analysis.
Hibiscus Anthocyanins Can Selectively Modulate Estrogen Receptor Activity with Favorable Toxicology: a Computational Analysis

The estrogen hormone receptor (ER) mediated gene expression mainly regulate the development and physiology of primary and secondary reproductive system alongside bone-forming, metabolism and behaviour. Over-expressed ER is associated with several pathological conditions and play a key role in breast cancer occurrence, progression and metastasis. Hibiscus sabdariffa L. or roselle is a rich source of naturally occurring polyphenolic compounds including anthocyanins and reportedly have strong estrogenic activity. To validate these findings, we have investigated the estrogen receptor binding affinity and safety of some previously recorded polyphenols using a suite of computational methods. Our investigation showed the estrogen-receptor binding potential of Pelargonidin, Delphinidin, Cyanidin, and Hibiscetin are more efficient than popular breast cancer drugs, Tamoxifen and Raloxifene, with favourable toxicological parameters and low half maximal inhibitory concentration. This is the first report to investigate the phytochemical basis of estrogenic activity of Hibiscus sabdariffa L.
IMPROVING WATER RESOURCES PLANNING AND MANAGEMENT INSTRUMENTS – FROM THE PROGRESSIVE WATER QUALITY GOALS TO THE TERRITORY MANAGEMENT

The implementation of the Brazilian National Water Resources Policy emphasizes the systematic planning and management of water resources without dissociating quantity and quality aspects. This also requires strategies that consider appropriate socio-economicenvironmental boundaries to encompass the diversity of the Brazilian territory and to promote integration of water resources, environmental planning articulated with land use management, different users and all distinct regional, state and national actors, in a given watershed. This paper highligths the necessity of a technical base for integrated water management that considers also land use and territorial management in critical basins. The environmental regulation allows for the definition of water quality goals defined in a progressive manner to achieve proper restoration of the water body to comply with designated uses. The definition of such restoration steps must be defined in accordance with territorial management perspectives and based on sound technical and scientific methods that include risk analysis perspective.
Beamformer development challenges for 5G and beyond

In this chapter, we first discussed the definitions that are vital to understand the working of a beamformer. We then classified the beamformer based on the architecture, frequency of operation and a use case. These clarifications are done keeping in mind the future technological advancements in the communication industry. Beamformer architectures are further divided into purely analog, digital and hybrid types, when each one of them has a specific need in specialized communication standards. Frequency bands of operations are divided into the well-known 5G sub bands that are sub-6-GHz and mmWave bands. We further discussed the ways in which a beamformer function differs when they are operating at different frequency bands. Lastly, we classified beamformers in terms of their utility as a fixed or mobile radio in a communication system. State-of-the-art beamformer examples are comparatively analyzed to better predict the most suitable choice for a given classification of beamformers in the 5G and beyond applications.
Visualization of beams from ionic liquid ion sources for focused ion beam applications

Ionic liquid ion sources (ILIS) share qualities with liquid metal ion sources necessary for focused ion beams (FIB) operation, such as pure ion emission and low energy spreads. These sources work at lower currents, room temperature, and are able to produce both positive and negative ions from a large number of ionic liquids. The influence of the applied voltage on the beam emitted from the ILIS based on the liquid EMI-BF4 (1-ethyl 3-methyl imidazolium tetrafluoroborate) is characterized by using a beam visualization system. As the applied voltage is increased, the source transitions from single to multiple beam emission. The visualization tool is also used to determine the spatial distribution of the neutral particle population contained within the beam emitted from ILIS. Cluster ions can break during flight, yielding a new ion and neutral particles. This neutral population can be highly energetic, and might be of interest for material treatment applications where charging of targets is undesirable. For F.
Postacute administration of the GABAA α5 antagonist S44819 promotes recovery of peripheral limb fine motor skills after permanent distal middle cerebral artery occlusion in rats

Background: Ischemic stroke causes hypoexcitability in the peri-infarct motor neocortex that stems from increased tonic γ-amino-butyric acid (GABA) activity in neurons. This hypoexcitability, while neuroprotective in the acute phase, may impair neuroplasticity and functional recovery in the subacute phase of stroke. The purpose of this study is to investigate the effect of delayed and prolonged administration of S44819, which is a potent and competitive selective antagonist of GABAA receptors, on the skilled reaching function in a rodent model of stroke. Methods: Male Sprague–Dawley rats (n = 15) were subjected to permanent middle cerebral artery occlusion. Starting 3 days after stroke, a vehicle or S44819 (3 or 10 mg/kg, BID) was delivered orally twice a day for 28 days. All animals were euthanized 2 weeks later after the washout period. A single pellet reaching task (SPR) was performed before (baseline value) and after the ischemic surgery at several time points (3, 10, 17, 24, 31, 38, and 45 days) to assess the motor deficit. Infarct volume and body changes were also evaluated. Results: S44819, administered at 10 but not 3 mg/kg, significantly improves SPR results over the 45 days after the ischemic surgery. No effect was observed in the infarct size and in the body weight over time between the groups investigated. Conclusion: S44819 at 10 mg/kg significantly enhances motor recovery on a skilled reaching task after sensory-motor cortex lesion. Additionally, our study, in light of the results of the RESTORE BRAIN (Randomized Efficacy and Safety Trial of Oral GABAA α5 antagonist S44819 after Recent ischemic Event) trial, may help clinicians to design clinical studies and stratify variables and patients adequately.
NEUTRON DIFFRACTION STUDY OF ICE POLYMORPHS. I. ICE IX.

Neutron‐diffraction spectra have been obtained at 80°K for polycrystalline D2O ice II prepared from ice Ih at 3 kbar and 195°K. An analysis of the 55 peaks in the 2θ diffraction angle between 10° and 57.3° has been made. The results of this study are in accord with the existence of a proton‐ordered arrangement for this ice as proposed by Kamb. Ice II has a rhombohedral unit cell with lattice parameters aR = 7.743 ± 0.002 A, αR = 113.09 ± 0.03°. Indexed on the triply primitive hexagonal cell, ice II has the parameters aH = 12.920 ± 0.003 A and cH = 6.234 ± 0.002 A at 80°K. The transformation of ice V to ice II by decompression at −35°C, an alternate way of forming ice II, has been observed to be slow. Although the O–O–O bonds in ice II are appreciably distorted from the tetrahedral arrangement found in ice Ih, the computer‐refined position parameters for the deuterons indicate that the D–O–D angles are 106° ± 3°. These results support the existence of bent hydrogen bonds in ice II.
Nanofluidic Cells with Controlled Pathlength and Liquid Flow for Rapid, High-Resolution In Situ Imaging with Electrons

The use of electron probes for in situ imaging of solution phase systems has been a long held objective, largely driven by the prospect of atomic resolution of molecular structural dynamics relevant to chemistry and biology. Here, we present a nanofluidic sample cell with active feedback to maintain stable flow conditions for pathlengths varying from 45 nm to several 100 nm, over a useable viewing area of 50 × 50 μm. Using this concept, we demonstrate nanometer resolution for imaging weakly scattering polymer and highly scattering nanoparticles side by side with a conventional transmission microscope. The ability to flow liquids allows control over sample content and on-the-fly sample exchange, opening up the field of high-throughput electron microscopy. The nanofluidic cell design is distinguished by straightforward, reliable, operation with external liquid specimen control for imaging in (scanning) transmission mode and holds great promise for reciprocal space imaging in femtosecond electron diffraction.
Smectite-type clay minerals as nanomaterials

Dilute aqueous smectite suspensions are well suited to convert into functional nanofilms. The functionalization is performed by ion exchange of amphiphilic molecules carrying the desired functionality. A functionalized clay mineral nanofilm is obtained by the organization of the molecules at the clay surface and by the organization of the elementary clay platelets in the film. Two techniques are presented: self-assembling and Langmuir-Blodgett (LB). Self-assembling is a very simple experiment, but the organizational order of the clay mineral particles is low. Nevertheless, films with nonlinear optical properties which are able to generate frequency-doubled light have been produced. The drawback of disorder of the clay platelets in the film can be largely overcome with the LB technique. Well organized films are obtained. In the presence of amphiphilic ruthenium(II)-bipyridine complexes, nonlinear optical properties are measured. In the presence of two dyes, oxacarbocyanine and rhodamine B, simultaneously adsorbed, efficient energy transfer between the donor (oxacarbocyanine) and the acceptor (rhodamine B) is measured. Fundamental research into the organization of molecules at clay mineral platelets is necessary to optimize the materials for specific applications.
Consumer Communication Deployment Tactics: An Integrated Framework for Lifestyle Brands and Retailers in India (CCF-LS)

Though consumer communication and orientation is a collective responsibility of all the departments/functions across the organization, a majority of lifestyle brands and retailers in India believe that the consumer communication is the deliverable of a single department/function that is widely and erroneously tagged as Marketing Department. This belief is distracting them from understanding the long-term positive impact on consumer patronage and they continue to use high-cost advertisements as one of the major tactics for consumer communication. A single theory, model and framework of consumer behavior from the existing literature available across perspectives, paradigms, and areas of study (Economics, Behavioral Economics, Psychology, Social Psychology, Anthropology, Marketing and so on) is not entirely applicable that could be adopted to suit lifestyle brands/retailers in India and designing a framework without empirical pieces of evidence is also not appropriate. In this study, i) we have studied over 28 consumer behavior theories, models and frameworks; ii) analyzed 24 months’ of actual data of a few select organized lifestyle brands and retailers in India; iii) borrowed experimental findings and insights from previous studies relevant in this context, to identify 50 factors influencing the outcomes of each stage of the consumer decision-making process and selected a few of them that have indicated the high scope of influencing capability by a lifestyle brand/retailer to design an economical and effective framework that is useful in designing consumer communication deployment tactics by a lifestyle brand or retailer in India. The framework is named as CCF-LS.
Neutron Single Crystal Diffraction on KDP at 20 K and 1. 7 GPa

In-situ neutron single crystal diffraction experiments on KH2PO4 (KDP) are reported. They were performed in a clamped pressure cell developed for the use in standard He-flow cryostats. The details of the structure of KDP in the paraelectric phase close to the ferroelectric phase transitionTc at a pressure of 1. 7 GPa and 20K were established. The resulting H. H separation δ in the disordered H-bond is 0. 26 (2) A with a corresponding O. O distance of 2R=2. 446 (3) A. These numbers deviate towards larger values from the established linear relationship of δ and 2R versus Tc.

Viscous Behavior of Imidazolium-Based Ionic Liquids

The viscosity of four imidazolium-based ionic liquids is analyzed as a function of pressure and temperature. Experimental measurements were carried out using an electromagnetic moving piston viscometer in the 303–353 K and 0.1–70 MPa ranges on synthesized ultrapure samples, and compared with available literature data. Molecular dynamics simulations were used to analyze the fluids’ dynamic properties from a nanoscopic viewpoint, with special attention paid to self-diffusion coefficients and dynamic viscosity. Simulated properties are in excellent agreement with experimental results in spite of the glasslike dynamics of some of the studied fluids.
Job Characteristics and Job Satisfaction among Office Workers: The Mediating Role of Distributive Justice

Job characteristics theory suggests five elements that benefit job satisfaction among employees. Using social exchange theory (SET), we hypothesize, the perception of distribution fairness will mediate the effect of autonomy and task identity on job satisfaction among office workers. 97 data collected on office workers from single organisation. Data analysed using hierarchical regression analysis. In support with the hypotheses, the findings demonstrate significant association between autonomy, task identity and distributive fairness with job satisfaction. The employees that have adequate job autonomy and acknowledge based on their effort will have higher satisfaction if they perceived the organisation practise fair rewards distribution. This study provide evidence on the role of distributive fairness as mediator in present context
Adsorption of Methylene blue onto Cajeput Tree Bark: Isotherm and Kinetic Studies

Cajeput tree bark was used as a low-cost adsorbent for the removal of methylene blue from aqueous solutions. The effects of pH, contact time and initial methylene blue concentration on adsorption capacity were studied in batch experiments. The experimental results indicated that the optimum pH for methylene blue adsorption was 7 and the adsorption equilibrium was achieved within 90 minutes. Equilibrium adsorption data were analyzed using Langmuir and Freundlich isotherms. The Langmuir isotherm fitted the equilibrium data better than the Freundlich isotherm. The maximum monolayer adsorption capacity of cajeput tree bark was found to be 64.43 mg/g. The pseudo-first-order and pseudo-second-order kinetic models were selected to describe the adsorption mechanism. Kinetic studies revealed that the adsorption kinetics of methylene blue followed the pseudo-second-order kinetic model. These results showed that cajeput tree bark can be used as an efficient low-cost adsorbent for the removal of methylene blue from aqueous solutions. Keywords: Adsorption, Methylene blue, Cajeput tree bark, Langmuir isotherm, Freundlich isotherm, Adsorption kinetic

—In this paper, a sputtering ceramic target based on SnO 2 doped with 2 at. % Co was synthesized by solid-phase reaction method. A chemiresisive alcohol vapor sensor based on SnO 2 <Co> was manufactured by the high-frequency magnetron sputtering method. The alcohol sensing properties of the SnO 2 <Co> sensor under the ultraviolet (UV) illumination were examined at room temperature. The UV-assisted alcohol sensor showed a sufficient response to low concentrations of alcohol vapor at room temperature. The Co-doped SnO 2 sensor has also demonstrated a good response to alcohol vapors at elevated operating temperature (200 °C).
Capacidad reproductiva de Pinus caribaea Morelet var. caribaea Barret y Golfari en la unidad de producción de semilla mejorada Marbajita

The study allows to evaluate the reproductive capacity of Pinus caribaea through the behavior of the reproductive indicators during two consecutive years. A sample of 109 cones was taken from trees in the improved seed production unit Marbajita-Cajalbana, corresponding to an area of natural pine forests in the municipality of La Palma. The characterization of their cones was made from their dimensions, besides determining the variables related to seed production such as fertile and infertile flakes, vain and full seeds, seed potential and efficiency, proportion of full and vain seeds, inbreeding index and germination percentage. Results related to cone length showed significant differences for the years evaluated, with the lowest values reported in 2016. High rates of inbreeding were evidenced above 12 %, acceptable for the species and for areas intended to produce improved seed. Germination was higher in 2017 with 100 %.
Approximating neural machine translation for efficiency

Neural machine translation (NMT) has been shown to outperform statistical machine translation. However, NMT models typically require a large number of parameters and are expensive to train and deploy. Moreover, its large model size makes parallel training inefficient due to costly network communication. Likewise, distributing and locally running the model for a client-based NMT model such as a web browser or mobile device remains challenging. This thesis investigates ways to approximately train an NMT system by compressing either the gradients or the parameters for faster communication or reduced memory consumption. We propose a gradient compression technique that exchanges only the top 1% of the most significant gradient values while delaying the rest to be considered for the next iteration. This method reduces the network communication cost by 50-fold but causes noisy gradient updates. We also find that Transformer–the current state-of-the-art NMT architecture–is highly sensitive to noisy gradients. Therefore, we extend the compression technique by restoring the compressed gradient with locally-computed gradients. We obtained a linear scale-up in parallel training without sacrificing model performance. We also explore transfer learning as a better method of initialising the training. With transfer learning, the model converges faster and can be trained with more aggressive hyperparameters. Lastly, we propose a log-based quantisation method to compress the model size. Models are quantised to 4-bit precision with no noticeable quality degradation after re-training combined with reserving the quantisation errors as feedback.
