A Stretchable Inductor With Integrated Strain Sensing and Wireless Signal Transfer

<italic>Objective:</italic> A soft and stretchable inductive sensor is presented with the ability to wirelessly transmit large strain measurements without the need for directly connected circuitry. <italic>Methods:</italic> The sensor is fabricated using a scaffold-removal technique to create microfluidic channels within an elastomer sheet (0.07 MPa modulus), which are injected with a non-toxic liquid metal alloy electrode. An analytical model is derived to predict the static inductance of the sensor while being uniaxially stretched and experimental characterisation of the sensor’s dynamic response to axial and biaxial deformation is conducted, as well as wireless measurements within ex-vivo porcine tissue. <italic>Results:</italic> Experimental validation showed that the sensor’s inductance change is linear with uniaxial and biaxial strains up to twice its original length. Strain-rate dependent hysteresis was negligible during slow deformation (<inline-formula> <tex-math notation="LaTeX">$ < {5} {s}^{-{1}}$ </tex-math></inline-formula>) and below 10% during more rapid changes in length (<inline-formula> <tex-math notation="LaTeX">$15\,\,{s}^{-{1}}$ </tex-math></inline-formula>). For wireless strain sensing, the variation of inductance in the sensor induced an increase in the transmitting voltage from 3.1 V to 5.7 V for strains up to 83%. While implanted within different layers of porcine tissue, the transmitter voltage linearly increased by 750 mV on average under bending deformation. <italic>Conclusion:</italic> Large stretching (83%) and bending (<inline-formula> <tex-math notation="LaTeX">$8\,\,{m}^{-{1}}$ </tex-math></inline-formula>) deformations in the inherently soft sensor can be wirelessly captured, including through biological tissue. <italic>Significance:</italic> The wireless sensor’s simplified structure, where the antenna and sensor are integrated into a single soft spiral electrode with modulus comparable to biological tissue, means that this novel design shows significant potential for implantable and wearable biomedical devices to monitor dynamic deformation.
(Perylene)3-(TCNQF1)2: Yet Another Member in the Series of Perylene–TCNQFx Polymorphic Charge Transfer Crystals

The 3:2 Charge Transfer (CT) co-crystal (Perylene)3(TCNQF1)2 is grown by the Physical Vapor Transport (PVT) method, and characterized structurally and spectroscopically. Infrared analysis of the charge sensitive modes reveals a low degree of charge transfer (less than 0.1) between donor and acceptor molecules. The crystal is isostructural to the other 3:2 CT crystals formed by Perylene with TCNQF2 and TCNQF4, whereas such stoichiometry and packing is not known for the CT crystals with non-fluorinated TCNQ. The analysis of the isostructural family of 3:2 Perylene–TCNQFx (x = 1,2,4) co-crystal put in evidence the role of weak F…HC bonding in stabilizing this type of structure
Host preferences of the cocoa pod borer, Conopomorpha cramerella, the main threat to cocoa production in Southeast Asia

Insects ensure the survival of their offspring by depositing their eggs in suitable environments. Even generalist egg‐laying insects often show preferences for specific host plants. The cocoa pod borer (CPB), Conopomorpha cramerella (Snellen) (Lepidoptera: Gracillariidae), successfully infests and reproduces on relatively few host plants, but has a major economic impact only on cocoa, Theobroma cacao L. (Malvaceae). Choice tests were performed in the laboratory to compare the frequency of insect visits, the duration of the visits, and the number of eggs laid on the fruits for each combination of host plants tested – that is, cocoa clones or fruits of rambutan (Nephelium lappaceum L.), Fijian longan (Pometia pinnata JR Forst & G Forst, both Sapindaceae), and langsat (Lansium domesticum Corrêa, Malvaceae). Our laboratory study showed that, when given the choice, CPB significantly favored cocoa pods over other host fruits (rambutan, langsat, or Fijian longan). Females also deposited more eggs on unripe fruits than on ripe fruits of similar size. The preference to lay eggs on specific cocoa clones in the bioassays did not reflect the level of the clone resistance to CPB damage reported from the field. Consequently, oviposition preference of female CPB does not seem to be the main factor explaining field resistance of some cocoa clones to CPB infestation.
Detecting stratigraphical issues using direct radiocarbon dating from small‐mammal remains

Frequently preserved in archaeological and palaeontological sites, the tiny size of small‐mammal remains favours percolations into underlying layers along stratigraphic sequences. This is one of the various post‐depositional processes that may affect the integrity of the original deposits and therefore the subsequent scientific interpretations. Recent developments in sample preparation offer the possibility of detecting intrusive episodes through the absolute dating of minute amounts of bone (down to 10 mg), meaning that isolated elements (such as mandibles in this case) are sufficient to obtain reliable radiocarbon dates if collagen is moderately to well preserved. The radiocarbon dates obtained here for small‐mammal bones (recovered from pre‐Bølling to recent deposits) and their comparison with previous dates obtained from other sources (large‐mammal bones, charcoal, botanical samples, etc.), with different protocols and instruments, illustrate the potential of small‐mammal dating to reveal (and eventually contribute a solution to) stratigraphical issues in different archaeological contexts.

Health on Wikipedia: a qualitative study of the attitudes, perceptions, and use of Wikipedia as a source of health information by middle-aged and older adults

ABSTRACT Wikipedia is one of the most popular online sources of information on a wide range of topics, including health and medical affairs. While a large body of research examines Wikipedia’s factual accuracy, few studies look at user perceptions and the actual use of the online encyclopaedia. Previous work has mostly explored students’ use of Wikipedia, but little is known about the attitudes of older generations of Internet users towards the online encyclopaedia. Based on 40 qualitative face-to-face interviews, this study explores the attitudes, perceptions, and use of Wikipedia as a source of health and medical information for middle-aged and older adults (50–80 years old) in Belgium. The study finds that six qualities and characteristics make Wikipedia an attractive source of health- and medical information: convenience, coverage, topicality, comprehensibility, conciseness, and familiarity. However, Wikipedia ultimately appears to play a limited role in the health management and decision-making practices of study participants as they use the online encyclopaedia primarily to obtain basic facts and general information. Furthermore, the doctor remains the most trusted and important source of information as well as the sole medical authority. Given the fact that the majority of respondents only possessed rudimentary knowledge of Wikipedia’s workings, Wikipedia might attempt to better explain how it operates and how health and medical entries are created and edited. Novel because of its qualitative approach and exploration of an understudied target audience, this study contributes original insights as well as nuances to prior Wikipedia user-centric studies.
Real-time Traffic Sign Text Detection Based on Deep Learning

Aiming at the task of traffic sign text detection in natural scenes, a two-stage cascade detection model based on deep learning is proposed. The proposed model first locates the regions of interest (RoI) of text-based traffic sign by applying improved SSD (Single Shot MultiBox Detector) network. Then a rotation-based text detection network is used to detect text strings in the located RoI. Moreover, the lightweight convolutional neural network MobileNetV2 is combined with the deep learning component in two stages, which reduces network parameters and improves detection speed of the model. On the one hand, the proposed approach takes full advantage of the information of traffic signs. By this way the search area of text detection can be reduced, which makes it possible to simplify the text detector. On the other hand, it can obtain more complete text detection results by using rotation-based text detector. The experimental results show that the proposed method can perform well on different data sets, it can not only keep a high accuracy of detection, but also meets the realtime requirements.
Penerimaan Sistem Informasi Berbasis Teknologi oleh Karyawan PT. Merry’s Tour and Travel Menggunakan Aplikasi Quickbooks

This research is intended to find out how the employee acceptance of the QuickBooks application system tested by Merry's Tour and Travel by using the Technology Acceptance Model (TAM). This study uses a population of all management and employees of Merry’s Tour and Travel. Determination of samples usingpurposive sampling techniques and the samples that met the criteria was 34 respondents. The data collection method uses a survey method with a questionnaire. Data were analyzed using Structural Equation Model (SEM), namely Partial Least Square (PLS). Based on the results of the analysis found that the variables of top management commitment, selft-efficacy, and perceived usefulness affect the acceptance of the QuickBooks information system at PT. Merry’s Tour and Travel. This indicates that the process of transition from manual systems to QuickBooks information systems cannot be fully explained by the Technology Acceptance Model.

Attention-deficit/hyperactivity disorder prediction using graph convolutional networks

Attention-Deficit/Hyperactivity Disorder (ADHD) is one of the most common childhood neuropsychiatric disorders, with characteristic symptoms of age-inappropriate levels of inattention, hyperactivity, and impulsivity that interfere with social and academic functioning. Recent studies have demonstrated that beyond purely neuroanatomical alterations, the disorder implies altered functional connectivity in several large-scale brain functional networks. In this study, we use the Graph Convolutional Networks (GCNs), which represent the population of patients and control subjects as a sparse graph. In this sparse graph, nodes are human subjects, which are associated with a brain connectivity-based feature vector, and edges are weighted using phenotypic information. We applied this framework on the large publicly available multi-institution ADHD-200 data repository of 921 resting-state functional MRI data sets. Using a 10k-fold cross-validation procedure, we obtain a mean accuracy of 76.95 and mean Area Under the receiver operating Curve (AUC) of 79.66 between typical controls and the ADHD Combined subtype. In addition, we performed classification between typical controls and all subtypes of ADHD patients, where we obtained a mean accuracy of 69.53 and mean AUC of 74.76, which outperforms the state-of-the-art methods in the literature. Our results suggest that resting-state functional MRI analysis with GCNs may provide contributions to developing biomarkers in ADHD and other neurological disorders.
A New In Situ Quasi-continuous Solar-wind Source of Molecular Water on Mercury

Radar observations of Mercury and the MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft data indicate the probable existence of water ice in the permanently shadowed polar regions. Generally, water is accepted to be of exogenous origin through delivery via comets and meteoritic impact. However, a continuous water formation process that involves thermal transformation of chemically stable mineral-bound hydroxyl groups produced by implanted solar-wind protons is readily available on the surface of Mercury. At typical temperatures prevailing on Mercury’s dayside surface, H2O can be produced from reactions involving OH groups on or within the H-saturated regolith grain interfaces. Similar reactions will also occur due to micrometeorite impact events on both the dayside and nightside. Once produced, H2O is released into the exosphere and then transported and processed via Jeans escape, photodissociation, dissociative adsorption, or condensation. Water reaching cold traps will be bound over geological periods. This simple water cycle will produce a highly chemically reduced surface and can deliver significant amounts of H2O to the permanently shadowed regions of Mercury over geological time periods. The overall process is an important but hitherto unnoticed source term that will contribute to the accumulation of water in the cold traps and polar regions of Mercury.
Induction of p100 Processing by NF-κB-inducing Kinase Involves Docking IκB Kinase α (IKKα) to p100 and IKKα-mediated Phosphorylation*

The processing of the nfκb2 gene product p100 to generate p52 is a regulated event, which is important for the instrumental function of NF-κB. We previously demonstrated that this tightly controlled event is regulated positively by NF-κB-inducing kinase (NIK) and its downstream kinase, IκB kinase α (IKKα). However, the precise mechanisms by which NIK and IKKα induce p100 processing remain unclear. Here, we show that, besides activating IKKα, NIK also serves as a docking molecule recruiting IKKα to p100. This novel function of NIK requires two specific amino acid residues, serine 866 and serine 870, of p100 that are known to be essential for inducible processing of p100. We also show that, after being recruited into p100 complex, activated IKKα phosphorylates specific serines located in both N- and C-terminal regions of p100 (serines 99, 108, 115, 123, and 872). The phosphorylation of these specific serines is the prerequisite for ubiquitination and subsequent processing of p100 mediated by the β-TrCP ubiquitin ligase and 26 S proteasome, respectively. These results highlight the critical but different roles of NIK and IKKα in regulating p100 processing and shed light on the mechanisms mediating the tight control of p100 processing. These data also provide the first evidence for explaining why overexpression of IKKα or its activation by many other stimuli such as tumor necrosis factor and mitogens fails to induce p100 processing.
Lens barrel design of the NIRST IR Camera

The use of uncooled microbolometer detectors for space infrared (IR) imaging application requires high optical throughput, which leads to very fast optical design (~f/1). This directly translates into stringent requirements for components, assembly and alignment. The Institut National d'Optique (INO) in Quebec City, Canada, designed such a system for the NIRST IR Camera. The instrument is part of the Aquarius/SAC-D satellite, a cooperative mission conducted jointly by NASA and the Comisión Nacional de Actividades Espaciales (CONAE) of Argentina. Due to the tight volume and mass allocation, the NIRST camera module is an all refractive design. Since the Camera is made of two lens barrels co-registered to cover the same ground area at different wavelength bands, it also adds coregistration alignment constraints. This paper presents the optomechanical solutions and alignment scheme that enabled the successful design and flight qualification. Trade-off study between thermally induced stress and structural stiffness of the lens RTV bond is discussed. Special attention is given to lens subcell alignment integrity under random vibration encountered during launch. Detailed Finite Element Analysis (FEA) is used to check early design assumptions. Test results of the final vibration campaign are also presented.
Arabic Speech Recognition System Based on MFCC and HMMs

Speech recognition allows the machine to turn the speech signal into text through identification and understanding process. Extract the features, predict the maximum likelihood, and generate the models of the input speech signal are considered the most important steps to configure the Automatic Speech Recognition System (ASR). In this paper, an automatic Arabic speech recognition system was established using MATLAB and 24 Arabic words Consonant-Vowel Consonant-Vowel Consonant-Vowel (CVCVCV) was recorded from 19 Arabic native speakers, each speaker uttering the same word 3 times (total 1368 words). In order to test the system, 39-features were extracted by partitioning the speech signal into frames ~ 0.25 sec shifted by 0.10 sec. in back-end, the statistical models were generated by separated the features into number of states between 4 to 10, each state has 8-gaussian distributions. The data has 48 k sample rate and 32-bit depth and saved separately in a wave file format. The system was trained in phonetically rich and balanced Arabic speech words list (10 speakers * 3 times * 24 words, total 720 words) and tested using another word list (24 words * 9 speakers * 3 times *, total 648 words). Using different speakers similar words, the system obtained a very good word recognition accuracy results of 92.92% and a Word Error Rate (WER) of 7.08%.
Solubilization of Sterols by Bile Salt Micelles and Monolayer Behavior of Mixed Systems of a Bile Acid with Different Sterols

In order to study thermodynamically the so-called lowering effect of plasma cholesterol level caused by dietary intake of phytosterols (plant sterols) or phytostanols, solubilization was investigated for the respective single systems of cholesterol (Ch), cholestanol (Chsta) and stigmasterol (Stig) and for their 1:1 mixed systems with two kinds of free bile salts (BS), sodium cholate (NaC) and sodium deoxycholate (NaDC), in pH 10 Kolthoff buffer solution at 37 °C. Even for the sterol / stanol solubilizates examined in the present study, compared with NaC, NaDC is stronger in solubilizing power, Sp, which is defined as the derivative of the solubilized amount, W, in mM by the total BS concentration, Ct (dW / dCt), as being expected in terms of hydrophobicity and aggregation number. The following findings were made i) the amount solubilized by both BS micelles follows the order: Ch > Chsta > Stig among the three single solubilizates, ii) Chsta is much stronger in the lowering ability than Stig in regard to Ch solubilization, and iii) from the 1 : 1 mixture of Ch with Chsta, Chsta is selectively solubilized (Ch is selectively excluded) by BS
[Opto-Electron Eng, 2020, 47(3)] Research advances of orbital angular momentum based optical communication technology

Orbital angular momentum (OAM) carried by the vortex beam provides a new dimension resource in the spatial domain of light waves, which attracting more and more researching attentions. Since the vortex beams with different OAM mode values are orthogonal to each other, the OAM mode is introduced into the field of traditional optical communication, and two new application mechanisms are derived: OAM shift keying (OAM-SK) and OAM division multiplexing (OAM-DM), which provides a potential solution for future high-speed, high-capacity and high-spectrum efficiency optical communication technologies. Based on the basic concepts and theories of OAM beam types and their generation methods, this paper will give a brief overview of typical research cases related to the application mechanisms of these two communication systems. Three key technologies have been discussed, including OAM beam multiplexing technology, OAM beam demodulation technology, and turbulence suppression technology of OAM-based optical communication. Finally, the future developing trends and prospects of OAM-based optical communication technology are analyzed and forecasted.
EMBRYO CULTURE AND IN VITRO CLONAL PROPAGATION OF OAK (Quercus aegilops L.)

An attempt was done to develop a micropropagation protocol for oak using embryo culture. Oak is considered a hard-to-root woody plant by conventional propagation methods, that’s why using tissue culture techniques is a very suitable alternative method. For oak embryo culture, WPM was used and found to be better than MS medium for embryo germination which gave 66.13%. As well as adding of GA3 to the medium improved the germination rate of embryos (43.25% and 82.25 %). At initiation stage, WPM was used and found to be the best medium by giving the highest number of shoots/ explant which was 1.80, the highest number of leaves (15.17 leaves/ explant) and the longest shoots (1.42 cm) followed by MS medium then GD which gave the lowest parameters which gave 0.98 shoots/ explant, 7.20 leaves/ explant and 1.06 cm shoot length. At shoot multiplication stage, BA was better than Kinetin for multiplication of oak explants. The addition of BA at 3 mg.l -l gave the highest number of shoot and leaves which were 3.33 and 26.11 respectively. The longest shoots were achieved when 4.5 mg.l -l of BA was used. Furthermore, kinetin at 3 and 4.5 mg -l gave the lowest parameters which were 1 cm in length and 1.54 leaves/ explant. For rooting stage, NAA was better than IAA in giving better parameters and rooting percentage. The highest number of roots and rooting percentage were achieved when 1 mg.l -l was added by giving 6 roots/ explant and 100% rooting percentage. While the longest roots were achieved when 0.5 mg.l -l of NAA was used (3.67 cm) followed by 1.5 mg.l -l IAA which gave 3.55 roots/ explant with rooting percentage 90%. The produced plantlets were successfully acclimatized and transferred to the open-air conditions with a rate reached 85%.
