Not Too Much, Nor Too Less: Investigating Which Information Should Be Shared for Awareness Between Remote Workers

Many companies are focusing on remote working since the Covid-19 pandemic. One difference between remote working environment and face-to-face setting is the absence of natural awareness, which promotes social interaction and helps coordination of work flow. To maintain the benefits of awareness in a remote working environment, it is important to first understand which information remote workers disclose and need for awareness. In this paper, we aim to investigate which information is disclosed and needed, and provide insights to mitigate the difference between the two. We conducted a case study with an actual workgroup of a university laboratory for a week. They disclosed and accessed each other's status information while working remotely. Then, a semi-structured interview asked why certain information was disclosed or accessed. Our results provide understanding over information sharing between remote workers for awareness in a post-pandemic world.
Na-K-ATPase isoform (α3, α2, α1) abundance in rat kidney estimated by competitive RT-PCR and ouabain binding

For understanding the regulation of sodium reabsorption, it is important to know whether the α 2 - or α 3 -isoform of Na-K-adenosinetriphosphatase (Na-K-ATPase) is expressed in mammalian kidney in addition to the predominant α 1 β 1 -isozyme. Here we applied competitive polymerase chain reaction (PCR) for estimation of mRNA in parenchymal zones of rat kidney for comparison to high-affinity [ 3 H]ouabain binding. The α 3 -isoform mRNA was demonstrated to form 0.04-0.05% of the amount of α 1 -isoform mRNA in the cortex, medulla, and papilla of rat kidney. The α 2 -mRNA was demonstrated in all three zones and constituted 0.03% of the amount of α 1 -mRNA in cortex. The abundance of the α 1 truncated mRNA was 0.1-0.8% of that of the α 1 -mRNA. The upper limit for expression of Na-K-ATPase isozyme with high ouabain affinity (dissociation constant, 69-141 nM) was 0.096-0.14% of the concentration of α 1 β 1 -Na-K-ATPase. Thus a small but well-defined pool of α 2 - and α 3 -isoforms constitutes ≤0.1% of the amount of α 1 -isoform at both the mRNA and protein level in rat kidney.

PViMat: A Self-Powered Portable and Rollable Large Area Gestural Interface Using Indoor Light

We present PViMat, a portable photovoltaic mat that can recognise six unique useful dynamic hover gestures up to 30 cm above the surface over a large area with more than 97% accuracy. We utilised an off-the-shelf portable and rollable outdoor solar tape and employed it to harvest indoor natural and artificial light energy to trickle charge a LiPo battery for self-powering. We demonstrate a low-power operation technique of continuous charging with DC photocurrent and simultaneous event-driven gesture recognition with AC photocurrent. The PViMat prototype harvests 30 mW in a general livingroom light level of 300 lux and consumes 0.8 mW per gesture. Lastly, we propose applications of PViMat with its large-area, flexible and rollable form-factors and the gesture set.
Experimental comparison of photoplethysmography-based atrial fibrillation detection using simple machine learning methods

The results of experimental studies on application of selected simple machine learning (ML) methods for detection of atrial fibrillation (AFib) based on photoplethysmogram (PPG) are presented in the paper. The goal of the studies was to compare the performance of AFib detection using different ML algorithms in short PPG segments containing 32 consecutive cardiac cycles. Four parameters describing time series of interbeat intervals (IBI) were derived from the time domain Heart Rate Variability (HRV) and used as features for classification algorithms. Optimal values of metaparameters for all considered ML algorithms were experimentally determined. Accuracy, sensitivity, specificity and F1-score were then calculated to measure the quality of detection performance of each classification algorithm.
An in vitro model to study adult neurogenesis in mammals

The wall of the lateral ventricle of bovine brains comprised three distinct layers: ependyma, subependyma (SE) and astroglial net. The wall lining white matter had narrow SE and thin, compacted astroglial net. The wall of the striatum and the anterior horn had a wide SE and a thick and slack astroglial net. The ependyma was S-100 positive and, in rostro-lateral regions, it developed basal processes and reactivity to GFAP and vimentin. The SE and the subjacent astroglial net displayed beta3 tubulin small cells and some PCNA positive nuclei. These features suggested that adult neurogenesis takes place in the bovine ventricular walls specially in the striatum and the anterior horn. Explants of the ependyma-SE were cultured in serum free medium. The ependymal cells developed a net of intermingled basal processes that became increasingly GFAP, vimentin and BLBP positive. At the same time SE cells proliferated to produce a population of beta3 tubulin-positive cells. These cells synthesised IGF-1 that acted as a survival factor. These explants represent good models to study adult neurogenesis.
The spermatheca in podotreme crabs (Crustacea, Decapoda, Brachyura, Podotremata) and its phylogenetic implications

Le sternum thoracique des crabes primitifs (Podotremata Guinot, 1977) est . fortement modifie chez la femelle au niveau des sutures 7/8, qui separent les deux derniers sternites, ce qui correspond a une specialisation secondaire des phragmes 7/8. Ainsi se developpe une spermatheque paire, qui est inter-segmentaire, internalisee et independante de l'orifice femelle sur la coxa du troisieme pereiopode. Elle est une exclusivite des Podotremata, etant completement distincte du receptacle seminal eubrachyourien. La spermatheque est etudiee chez tous les representants de Podotremata, dans son aspect externe et dans sa structure interne. Parmi les Dromiacea, un tube se specialise chez les Homolodromiidae, Dromiinae et Hypoconchinae, tandis qu'il est absent chez les Dynomenidae et les Sphaerodromiinae, suggerant que les Sphaerodromiinae sont basaux par rapport aux Hypoconchinae + Dromiinae et que les Dynomenidae sont basaux par rapport aux autres familles de dromiaces. Les implications phylogenetiques sont discutees, confirmant la distinction de deux clades basaux, Dromiacea et Homolidea, l'organisation particuliere des Cyclodorippidae, Cymonomidae et Phyllotymolinidae, ainsi que la condition tout a fait speciale des Raninoidea. La spermatheque paire s'avere etre la plus forte synapomorphie des Podotremata, y compris deux familles du Cretace. Des hypotheses sur le stockage du sperme par la femelle, le fonctionnement de la spermacheque, le transfert du sperme, le role des gonopodes dans l'insemination et sur les modalites de fertilisation sont formulees. Des donnees nouvelles sur le squelette axial sont apportees. L'etude de la spermatheque, qui a une valeur considerable pour la phylogenie des decapodes, conduit a une discussion sur la monophylie des Brachyura, en tenant compte des donnees paleontologiques.
A land cover-driven approach for fitting satellite image time series in a change detection context

Thanks to the freely availability of several Satellite Image Time Series (SITS) covering the Earth, it is now possible to monitor and analyse Land Covers (LC) and Land Cover Changes (LCC) on a yearly or even longer time span. Such applications are relevant in the context of Climate Change (CC), where consequences of the changes can only be seen on long term. Nevertheless, SITS suffer from atmospheric condition related problems (when talking about passive sensors) that reduce the temporal resolution of images in SITS. Several methods have been proposed in literature to mitigate these problems, and are placed under gap filling or SITS fitting methods. Such methods generally work with a single feature, being it a radiometric index or a spectral band. The use of multiple features is limited to specific single LC class or satellite sensor, limiting its usage in LCC and CC. Thus, in this paper, we propose an approach that is automatic, and both LC and feature independent. Here we propose the use of Normalized Difference Indices (NDI), with combination of all available spectral bands. The proposed approach uses a dropout upper-envelope strategy to reconstruct SITS trends, based on a set of rules, and guarantees a smoother closer trend to that of the original data. The proposed approach has been applied over two regions (Amazonia and Saudi Arabia) in the period 2013-2017, and has been compared to other fitting methods: Cubic Splines and Univariate Splines. It has been further evaluated by detecting LCC with long SITS methods such as Breaks For Additive Seasonal and Trend (BFAST). The preliminary results are promising demonstrating the robustness of the approach across different LCs and across different features.
Investigation of some limitations of non-line-of-sight scene reconstruction

In the past decade, optical non-line-of-sight (NLOS) sensing has evolved from a fundamental idea and laboratory proof-of-principle experiment to a more and more mature computational sensing method to obtain information which cannot accessed with conventional optical means. For instance, reconstruction of NLOS scenes has been demonstrated with large round trip path length, outdoors and in real-time. To reach this state of art, various powerful reconstruction algorithms and transient rendering software has been developed. Detailed reconstructions of complex scenarios show the feasibility of this technology to be used in various sensing tasks ranging from military and security operations to civilian search and rescue missions and scientific (e.g. archaeology) and medical sensing tasks. Nevertheless, the sensing and reconstruction limitations are not completely understood. This paper starts to discuss the necessary information to interpret NLOS data sets and reconstructions.
Extremely low-noise avalanche photodiodes based on AlAs0.56Sb0.44

This paper presents the electron and hole avalanche multiplication and excess noise characteristics based on bulk AlAs0.56Sb0. 44 p-i-n and n-i-p homojunction diodes lattice matched to InP, with nominal avalanche region thicknesses of 0.6 -1.5 μm. From these, the bulk electron and hole impact ionization coefficients (α and β respectively), have been determined over an electric field range of 220-1250 kV/cm for α and from 360-1250 kV/cm for β for the first time. Excess noise characteristics suggest an β/α ratio as low as 0.005 for an avalanche region of 1.5 μm in this material, close to the theoretical minimum and significantly lower than AlInAs, InP, or even silicon. This material can be easily integrated with InGaAs for networking and sensing applications, with modeling suggesting that a sensitivity of -32.1 dBm at a bit-error rate (BER) of 1×10-12 at 10 Gb/s at 1550 nm can be realized. This sensitivity can be improved even further by optimizing the dark currents and by using a lower noise transimpedance amplifier.
Erectogenic, Antihypertensive, Antidiabetic, Anti-Oxidative Properties and Phenolic Compositions of Almond Fruit (Terminalia catappa L.) Parts (Hull and Drupe) – in vitro

This study was conducted to determine the effects of almond (Terminalia catappa L.) fruit parts (hull and drupe) extracts on key enzymes (arginase, angiotensin-1-converting enzyme, α-amylase and α-glucosidase) relevant to erectile dysfunction, type-2 diabetes and hypertension, assess their antioxidant properties and characterize their phenolic constituents. The hull and drupe extracts were prepared by a mixture of absolute methanol and 1N HCl, evaporated to dryness and used for subsequent analysis. The result revealed that the hull and drupe extracts inhibited arginase, angiotensin-1-converting enzyme, α-amylase and α-glucosidase activities in a dose-dependent manner. Both extracts scavenged radicals, reduced Fe3+ to Fe2+, chelated Fe2+ and inhibited lipid peroxidation in rat penile homogenate in vitro. Chlorogenic acid, ellagic acid and kaempferol were identified as the major phenolic compounds. This study suggests that these fruit parts can be natural sources of erectogenic, antihypertensive antidiabetic and anti-oxidative agents. However, the hull showed better potential than the drupe. Practical Applications The results suggest that Almond (Terminalia catappa L.) fruit parts, including the hull and drupe, have potential applications as functional foods and nutraceuticals for both animal and human nutrition. In addition, the hull and drupe could be useful for therapeutic purposes as erectogenic, antihypertensive, antidiabetic and anti-oxidative agents.
Swipe&Switch: Text Entry Using Gaze Paths and Context Switching

Swipe-based methods for text entry by gaze allow users to swipe through the letters of a word by gaze, analogous to how they can swipe with a finger on a touchscreen keyboard. Two challenges for these methods are: (1) gaze paths do not possess clear start and end positions, and (2) it is difficult to design text editing features. We introduce Swipe&Switch, a text-entry interface that uses swiping and switching to improve gaze-based interaction. The interface contains three context regions, and detects the start/end of a gesture and emits text editing commands (e.g., word insertion, deletion) when a user switches focus between these regions. A user study showed that Swipe&Switch provides a better user experience and higher text entry rate over a baseline, EyeSwipe.
Haptic Reproduction by Pneumatic Control Method Based on Load-Displacement Profile

It is known that the pressure and contact area change contribute to hard and soft perception as a cutaneous sensation. In this study, we propose a novel method of haptic presentation based on the profiles of physical objects by using the load-displacement measurement. We fabricated a pneumatic haptic system with an elastic membrane that enables controlled pressure stimuli. We verified that the proposed method is capable of reproducing various profiles by comparing with physical objects. As a result, we found that our system could well reproduce the load-displacement profiles of a sponge and a button specimen.
Multimodal emotion classification by streaming fixed time segments for speaker movies

The approach to Video-Audio Emotion Recognition takes advantage of gaining additional information from multimodalites. Since the target features are time related without strict alignment in time, video-audio features become simply video features and audio features. Exploring toward such a goal, spectrogram as outstanding vocal feature in neural network solution is selected to get benefits of convolution filters. Inspired by solution of image captioning of LSTM where embedded words information and image information are spatially aligned, we perform embedding of the audio spectrogram and image sequences since time information is converted to spatial information in spectrogram. We propose both architecture and framework optimizing the alignment of the mentioned temporal features and we provide the analysis of the significant performance improvement along with the discussion of the Video-Audio Emotion Recognition general tasks.
Remote sensing and food security: monitoring agriculture, ecosystems, hydrology, food environments, and health outcomes

There are substantial challenges in providing safe, affordable, and nutritious food for a healthy and active human population globally. At present, instances of undernourishment and micronutrient deficiencies are widespread and occur in the same communities as obesity – forming what has been termed as the ‘triple burden of malnourishment’. This triple burden of malnourishment affects the health of individuals, increases demand for medical services, and can reduce the productive capacity of a society. Concurrently, ecological and atmospheric conditions are approaching critical tipping points that will have a bearing on the ecosystems services that are required to produce our food. By 2064, the human population is predicted to reach 9.7 billion people – 2 billion more than 20201 . With this growth in population it will be increasingly challenging to address the triple burden of malnourishment and maintain or improve ecosystem services. This introduction serves as a brief overview of how remote sensing has been employed to inform decisions that will address these challenges.

Twenty-three laboratories conducted analyses using performic acid oxidation with acid hydrolysis-sodium metabisulfite method, 16 laboratories performed analyses using performic acid oxidation with acid hydrolysis-hydrobromic acid method, and 15 laboratories used acid hydrolysis method
Structural Basis of Inhibition of Human Insulin-Regulated Aminopeptidase (IRAP) by Benzopyran-Based Inhibitors

Inhibition of the insulin-regulated aminopeptidase (IRAP) improves memory and cognition in animal models. The enzyme has recently been crystallized and several series of inhibitors reported. We herein focused on one series of benzopyran-based inhibitors of IRAP known as the HFI series, with unresolved binding mode to IRAP, and developed a robust computational model to explain the structure-activity relationship (SAR) and potentially guide their further optimization. The binding model here proposed places the benzopyran ring in the catalytic binding site, coordinating the Zn2+ ion through the oxygen in position 3, in contrast to previous hypothesis. The whole series of HFI compounds was then systematically simulated, starting from this binding mode, using molecular dynamics and binding affinity estimated with the linear interaction energy (LIE) method. The agreement with experimental affinities supports the binding mode proposed, which was further challenged by rigorous free energy perturbation (FEP) calculations. Here, we found excellent correlation between experimental and calculated binding affinity differences, both between selected compound pairs and also for recently reported experimental data concerning the site directed mutagenesis of residue Phe544. The computationally derived structure-activity relationship of the HFI series and the understanding of the involvement of Phe544 in the binding of this scaffold provide valuable information for further lead optimization of novel IRAP inhibitors.
