Automatically Generated Smartphone Data in Young Patients With Newly Diagnosed Bipolar Disorder and Healthy Controls

Background: Smartphones may facilitate continuous and fine-grained monitoring of behavioral activities via automatically generated data and could prove to be especially valuable in monitoring illness activity in young patients with bipolar disorder (BD), who often present with rapid changes in mood and related symptoms. The present pilot study in young patients with newly diagnosed BD and healthy controls (HC) aimed to (1) validate automatically generated smartphone data reflecting physical and social activity and phone usage against validated clinical rating scales and questionnaires; (2) investigate differences in automatically generated smartphone data between young patients with newly diagnosed BD and HC; and (3) investigate associations between automatically generated smartphone data and smartphone-based self-monitored mood and activity in young patients with newly diagnosed BD. Methods: A total of 40 young patients with newly diagnosed BD and 21 HC aged 15–25 years provided daily automatically generated smartphone data for 3–779 days [median (IQR) = 140 (11.5–268.5)], in addition to daily smartphone-based self-monitoring of activity and mood. All participants were assessed with clinical rating scales. Results: (1) The number of outgoing phone calls was positively associated with scores on the Young Mania Rating Scale and subitems concerning activity and speech. The number of missed calls (p = 0.015) and the number of outgoing text messages (p = 0.017) were positively associated with the level of psychomotor agitation according to the Hamilton Depression Rating scale subitem 9. (2) Young patients with newly diagnosed BD had a higher number of incoming calls compared with HC (BD: mean = 1.419, 95% CI: 1.162, 1.677; HC: mean = 0.972, 95% CI: 0.637, 1.308; p = 0.043) and lower self-monitored mood and activity (p's < 0.001). (3) Smartphone-based self-monitored mood and activity were positively associated with step counts and the number of outgoing calls, respectively (p's < 0.001). Conclusion: Automatically generated data on physical and social activity and phone usage seem to reflect symptoms. These data differ between young patients with newly diagnosed BD and HC and reflect changes in illness activity in young patients with BD. Automatically generated smartphone-based data could be a useful clinical tool in diagnosing and monitoring illness activity in young patients with BD.
Vacteens.org: A Mobile Web app to Improve HPV Vaccine Uptake

U.S. HPV vaccine uptake remains below the Healthy People 2030 goal of 80% series completion. Parental concerns and misinformation about the efficacy and safety of the Human Papillomavirus (HPV) vaccine remain, and may be addressed by digital interventions tailored to their concerns. Reported here are results from a small scale randomized trial testing a mobile web app for parents and their adolescent daughters (ages 11–14 years) encouraging HPV vaccination in New Mexico, an ethnically-diverse U.S. state. Methods: A clinic-cluster randomized trial where pediatric clinics (n = 9) were recruited and randomized, and parent-adolescent pairs (n = 82) within clinics received either the Vacteens.org/Vacunadolescente.org mobile web app or Usual and Customary (UC) HPV Vaccination information. Parents completed online surveys at baseline and 3-months. Daughters' HPV vaccine data were collected from the New Mexico State Immunization Information System 1 year post baseline. Results: Three month survey results found Vacteens.org/Vacunadolescente.org parents to have higher positive HPV vaccine beliefs, informed decision making, intent to vaccinate and vaccine confidence outcomes than UC parents. HPV vaccine data found higher first dose HPV vaccination (Pearson χ2 = 6.13, p = 0.013, Vacteens.org/Vacunadolescente.org group 59.4%, UC group 40.6%), and higher HPV vaccination series completion (Pearson χ2 = 6.49, p = 0.011, Vacteens.org/Vacunadolescente.org group 68.4%, UC group 31.6%). Conclusions: The small trial results showed the Vacteens.org/Vacunadolescente.org web app prompted positive vaccine-related attitudes and beliefs, and more HPV vaccination initiation and series completion. Mobile web apps can make decision-making tools for HPV vaccination widely available on digital platforms, reducing vaccine hesitancy, and confusion and increase HPV vaccine uptake.
Arbuscular Mycorrhizal Symbiosis Triggers Major Changes in Primary Metabolism Together With Modification of Defense Responses and Signaling in Both Roots and Leaves of Vitis vinifera

Grapevine (Vitis vinifera L.) is one of the most important crops worldwide but is subjected to multiple biotic and abiotic stresses, especially related to climate change. In this context, the grapevine culture could take advantage of symbiosis through association with arbuscular mycorrhizal fungi (AMF), which are able to establish symbiosis with most terrestrial plants. Indeed, it is well established that mycorrhization improves grapevine nutrition and resistance to stresses, especially water stress and resistance to root pathogens. Thus, it appears essential to understand the effect of mycorrhization on grapevine metabolism and defense responses. In this study, we combined a non-targeted metabolomic approach and a targeted transcriptomic study to analyze changes induced in both the roots and leaves of V. vinifera cv. Gewurztraminer by colonization with Rhizophagus irregularis (Ri). We showed that colonization of grapevine with AMF triggers major reprogramming of primary metabolism in the roots, especially sugar and fatty acid metabolism. On the other hand, mycorrhizal roots had decreased contents of most sugars and sugar acids. A significant increase in several fatty acids (C16:1, linoleic and linolenic acids and the C20 arachidonic and eicosapentaenoic acids) was also detected. However, a downregulation of the JA biosynthesis pathway was evidenced. We also found strong induction of the expression of PR proteins from the proteinase inhibitor (PR6) and subtilase (PR7) families in roots, suggesting that these proteins are involved in the mycorrhiza development but could also confer higher resistance to root pathogens. Metabolic changes induced by mycorrhization were less marked in leaves but involved higher levels of linoleic and linolenic acids and decreased sucrose, quinic, and shikimic acid contents. In addition, Ri colonization resulted in enhanced JA and SA levels in leaves. Overall, this study provides a detailed picture of metabolic changes induced by AMF colonization in a woody, economically important species. Moreover, stimulation of fatty acid biosynthesis and PR protein expression in roots and enhanced defense hormone contents in leaves establish first insight in favor of better resistance of grapevine to various pathogens provided by AMF colonization.
Synthesis, characterization, and properties of novel UV-resistant poly(urethane-imide)/POSS nanocomposite

In this study, a series of hybrid nanocomposites composed of poly(urethane-imide) (PUI), fluoroethylene vinyl ether copolymers, and octa-aminophenyl polyhedral oligomeric silsesquioxane (POSS) were successfully prepared. Fourier transform infrared spectroscopy, scanning electron microscopy (SEM), contact angle analysis, thermogravimetric analysis (TGA), and dynamic mechanical analysis were used to characterize the hybrid nanocomposites, which were found to have excellent thermostability, mechanical strength, and ultraviolet (UV) resistance. The SEM results showed that POSS nanoparticles, at low content level, could disperse homogeneously in the PUI matrix. The TGA results confirmed that the thermostability of the hybrid nanocomposites was significantly improved by the addition of POSS. Moreover, the UV-resistant property of the nanocomposites was evaluated based on the change in mechanical property and weight loss caused by the UV radiation. POSS (5 wt%) achieved the highest efficiency in enhancing the UV resistance of the nanocomposites. After UV radiation, the tensile modulus of the nanocomposite without POSS decreased to 187 MPa, and the mass loss was 7.26%. In contrast, the tensile modulus of the nanocomposite containing 5 wt% POSS increased from 412 MPa to 444 MPa, and the mass loss was only 3.76%.
Fast Large-Margin Learning for Statistical Machine Translation

Statistical Machine Translation (SMT) can be viewed as a gene-rate-and-select process, where the selection of the best translation is based on multiple numerical features assessing the quality of a translation hypothesis. Training a SMT system consists in ﬁnding the right balance between these features, so as to produce the best possible output, and is usually achieved through Minimum Error Rate Training (MERT). Despite several improvements, training remains one of the most time consuming step in the development of SMT systems and is a major bottleneck for experimentations. Building on recent advances in stochastic optimization and online machine learning, this paper studies a possible alternative to MERT, based on standard and well-understood algorithms. This approach is shown to deliver competitive solutions, at a much faster pace than the standard training machinery.
Longiflorol, a bergenin α-d-apioside from the stem bark of Diospyros longiflora, and its antioxidant activity

Abstract Phytochemical investigation of the stem bark of Diospyros longiflora yielded longiflorol (1), a new bergenin α-d-apioside, together with bergenin (2) and five known compounds: lupeol (S1), betulin (S2), betulinic acid (S3), stigmasterol (S4) and stigmasterol glucoside (S5). Their structures were determined by one-dimensional (1D) and 2D nuclear magnetic resonance experiments along with electrospray ionization high-resolution mass spectrometry and extended density-functional theory calculations of chiroptical properties. Longiflorol (1) and bergenin (2) were evaluated for their DPPH (2,2-diphenyl-1-picrylhydrazyl) antioxidant activity, with the crude extract for comparison and ascorbic acid as standard. The results showed that the extract and 2 had good antioxidant activity, whereas 1 showed only moderate activity at high concentration (>2 mg mL−1).
Linking Named Entities to a Structured Knowledge Base

The task of entity linking aims at associating named entities with their corresponding entries in a knowledge base. The task is challenging because entities, can not only occur in various forms, viz: acronyms, nick names, spelling variations etc but can also occur in various contexts. To extract the various forms of an entity, we used the largest encyclopedia on web, Wikipedia. In this paper, we model entity linking as an Information Retrieval problem. Our experiments using TAC 2009 knowledge base population data set show that an Information Retrieval based approach fares slightly better than Naive Bayes and Maximum Entropy.
Antidiabetic Effects of Essential Oils of some Selected Medicinal Lamiaceae Plants from Yemen against α-Glucosidase Enzyme

Essential oils of four species used in traditional medicine in Bani Matar District in Yemen, family Lamiaceae were assessed chemically and biologically for their antidiabetic activity; Leucas inflata, Marrubium vulgare, Salvia schimper and Origanum majorana. The results indicated that Salvia schimperi essential oil exhibited the most dosedependent inhibitory activity against α-gucosidase enzyme with IC50 of 14.26 μL (nearly similar to acarbose of IC50 12.87 μL) followed by Marrubium vulgare oil with IC50 value at 35.47 μL. Leucas inflata essential oil exhibited weak dose-dependent inhibitory activity against α-glucosidase enzyme with IC50 of 159.66 μL and no effect was observed with Origanum majorana. The antidiabetic activities observed was due to the presence of compounds such as caryophyllene, bisabolol and farnesene. Our results obviously cleared that essential oils of Salvia schimperi and Marrubium vulgare exerted promising antidiabetic effects so; we recommended using such as oils as futural natural antidiabetic.
Adsorption of Carbon Tetrahalides on Coronene and Graphene

Since carbon tetrahalides CX4 (X = Cl/Br) are adsorbed on carbon nanotubes and graphene sheets, we have studied the structures, adsorption energies, and electronic properties of CX4 adsorbed on benzene, coronene, and graphene using dispersion corrected density functional theory (DFT) with hybrid functionals. As compared with the benzene–CX4 complexes (with binding energy of ∼14/15 kJ/mol) where electrostatic energy is significant due to the halogen bonding effect, the graphene–CX4 complexes show about three times the benzene–CX4 binding energy (∼40/45 kJ/mol) where the dispersion interaction is overwhelming with insignificant electrostatic energy. Since the X atoms in CX4 are slightly positively charged and the X atom’s ends are particularly more positively charged due to the σ-hole effect, CX4 behaves as an electron acceptor. This results in electron transfer from locally negatively charged C sites of benzene/coronene to CX4. In contrast, no electron transfer occurs from graphene to CX4 because of the la.
Improving Shelf Life and Quality of Daddawa Made by Fermentation of Soya Beans and Sorrel Seeds from Maiduguri, North-East Nigeria IMPROVING SHELF LIFE AND QUALITY OF DADDAWA MADE BY FERMENTATION OF SOYA BEANS AND SORREL SEEDS FROM MAIDUGURI, NORTH-EAST NIGERIA

Daddawa is a Hausa name for a fermented product made from seeds of plants such as soya bean, locust bean, baobab and castor seeds. This product serves as flavour enhancers in soups in many homes in Nigeria. Sorrel seeds are less competitive sources of amino acids and proteins that is cultivated all year round in many parts of northern Nigeria. This study evaluated the biochemical properties of a fermented daddawa made from combination of soybeans (Glycine max) and sorrel (Hibiscus sabdariffa) seeds (3:1 and 1:3 ratios). Both combinations resulted in daddawa product with significantly higher (p< 0.05) soluble proteins, amino acids and titrable acidity relative to the unfermented sample. The product made from the 3:1 soybeans and sorrel seed combination ratio had the highest concentration of amino acid (29.0 ± 1.0 mg/g sample) at 60 h of fermentation while those made from the 1:3 ratio had the highest amino acid concentration (32.0 ± 1.0 mg/g sample) at 36 h. Reducing sugar concentrations were significantly lower (p < 0.001) in the fermented daddawa product compared to the unfermented sample for both combinations. Storage with vitamins C and E significantly decreased (p < 0.001) the levels of soluble proteins and amino acids in the product made from the 3:1 soybeans and sorrel seed combination. The vitamin containing stored daddawa product had significantly higher (p < 0.05) titrable acidity concentration. This study has shown the addition of vitamin C and E on daddawa made from a combination of soya bean and sorrel seeds to be inadequate in preserving nutrients during storage.
I was here: a system for creating augmented reality digital grafﬁti in public place

Since ancient times travelers and tourists try to leave their marks in places they visit. However, carving or writing on historic landmarks can cause irreversible damage on such sites. One possible solution are digital graﬃti. These can for example be created through projection mapping where beams of light wrap the object with the digital graﬃti created by users so everyone at the site can see them. However this may disturb other visitors being there at the same time. In this paper we explore an alternative solution for creating digital graﬃti by utilizing Mobile Augmented Reality (MAR) technology. We developed a mobile application which allows users to: (i) select an object or a building, (ii) map a 3D mesh onto it in order to prepare its 2D plane , and (iii) draw a graﬃti on this plane. After completing the drawing the application wraps the object or the building with a modiﬁed 2D texture creating an illusion of digital graﬃti. In order to (i) evaluate the social acceptance of placing digital graﬃti onto historic landmarks and to (ii) evaluate if the use of our prototype is socially acceptable in public spaces, we carried out a small reﬂective user study. We created a couple of simple graﬃti on diﬀerent historic buildings and posted them on social networking site Facebook. Despite amateur appearance, posted photos received attention and generated some positive responses and questions.
The Solar Neighborhood XLVIII: Nine Giant Planets Orbiting Nearby K Dwarfs, and the CHIRON Spectrograph’s Radial Velocity Performance

We report initial results of a large radial velocity survey of K dwarfs up to a distance of 50 pc from the solar system, to look for stellar, brown dwarf, and Jovian planets using radial velocities from the CHIRON spectrograph on the CTIO/SMARTS 1.5 m telescope. We identify three new exoplanet candidates orbiting host stars in the K dwarf survey and confirm a hot Jupiter from TESS orbiting TOI 129. Our techniques are confirmed via five additional known exoplanet orbiting K dwarfs, bringing the number of orbital solutions presented here to 9, each hosting an exoplanet candidate with a minimum mass of 0.5–3.0 M Jup. In addition, we provide a list of 186 nearby K dwarfs with no detected close companions that are ideal for more sensitive searches for lower-mass planets. This set of stars is used to determine CHIRON’s efficiency, stability, and performance for radial velocity work. For K dwarfs with V = 7–12, we reach radial velocity precisions of 5–20 ms−1 under a wide range of observing conditions. We demonstrate the stability of CHIRON over hours, weeks, and years using radial velocity standards, and describe instrumental capabilities and operation modes available for potential users.
Angga Septiyanto, Pengaruh Methanol (CH3OH) terhadap Emisi Soot Mesin Diesel Injeksi Tidak Langsung Pengaruh Methanol (CH3OH) terhadap Emisi Soot Mesin Diesel Injeksi Tidak Langsung Effect of Methanol (CH3OH) on Soot Emissions Indirect Injection Diesel Engines

Methanol when used as a fuel additive has the potential to reduce soot emissions. Methanol is added to diesel fuel in an effort to reduce soot emissions from diesel engines. The mixing of high purity methanol in diesel fuel is carried out with a percentage of 0% (D100), 5% (M5D95), 10% (M10D90), and 15% (M15D95). The results showed that there was a reduction in soot emissions and fuel consumption when using a mixture of methanol and diesel fuel. The value for reducing soot emissions and fuel consumption for indirect injection diesel engines was the highest when using the M5D95 fuel mixture, by 47.27% and 13.52%. The M5D95 fuel mixture becomes a type of mixture that effectively reduces soot emission levels and fuel consumption from indirect injection diesel engines
Online Resourcing in Maritime English Teaching: The Teachers’ Challenges

Due to the Covid-19 pandemic, a sudden shift of learning model to online system has brought new challenges to the teachers. They are obliged to adapt and conduct new classroom practices to ensure an effective teaching and learning process is carried out. These new teaching practices are applied in the whole teaching process, from planning to evaluating processes. These include material resourcing, material development, material delivery, and assessment. This paper presents a micro-study focusing on how Maritime English (ME) teachers in Jakarta adapt to the online teaching and learning process in material resourcing and delivering processes. The data were collected through an online questionnaire distributed to twenty-one ME Teachers at high school and higher education levels. The results show that the teachers find it challenging to adapt to online learning and tried their utmost by using whatever resources they have in their hands. However, there is a lack of consideration in using proper online resources to achieve the learning objectives.
PREPARATION AND CHARACTERIZATION OF SUPER-BLACK SURFACE COATING USING CARBON NANOMATERIALS

Super-black material absorbs almost all light that falls on it, because little light can be transmitted or reflected. With this unique property, super-black material can be applied to many fields, such as optical sensor, solar energy absorber, black body calibration and so on. Especially, optical baffles with super-black surface is critical to suppress the stray light for the detectors of the satellites [1]. Hence, various process and materials have been developed to blacken the surface by chemical treatment [2], plating [3] and painting [4]. Meanwhile, most researches fabricated the super-black surface on a small scale in laboratory, rather than ones with high performance in practical application. This paper provided an efficient and cost-effective approach to achieve a super-black surface by combining spray coating of carbon nanocomposite with periodic micro surface structure. Carbon is a good absorber because of the π-band’s optical transitions [5], so carbon nanotube (CNT) solution was sprayed on the Cu or PI substrate to enhance light absorption. Polymers and dispersant were also added into the coating to increase adhesion and uniformity. Total reflectance of as-prepared carbon nanocomposite coating is less than 8% in visible region (as shown in Fig.1 (a)). Yet the absorption was limited because of the moderate reflection at the air-dielectric interface. Therefore, conical periodic micro structure was processed on the coating surface to form a gradual change of effective refractive indices between air-dielectric interface. Figure 1: Laser engraving system to prepare micro structure. A CO2 laser engraving system was employed to prepare the micro structure (as shown in Fig.1 ). Through changing the laser path and power, conical periodic structure with an average height about 5μm and interval length of 100μm was prepared successfully (as shown in Fig.1 (b)). Total reflectance of the as-prepared coating decreased to 3% in visible region, 47% lower than that of the unprocessed coating. This laser texturing method has high efficiency and can be applied to different surface shapes. Combined flexible spray-coating method with effective laser surface texturing process, this surface coating has good adaptability as well as high light absorption performance in practical application.

Sharing tacit knowledge in public sector: assessing local administrators’ perspectives in Bangladesh

Tacit knowledge – experiences, skills, judgment and even intuition of the employees – as organizational resource, has recently gained significant attention from the organizational researchers. While such knowledge is difficult to identify, exhibit and describe, it can often determine the manner in which public administrators implement public policies. Taking a qualitative strategy of enquiry, this paper aims at identifying the pattern of tacit knowledge sharing among the local government officials in Bangladesh. The key findings suggest that majority of the local government officials are aware of the significance of tacit knowledge. Trust, both cognition-based trust and affect-based trust, determine their knowledge sharing behaviour. The ‘seniorjunior’ relationship within the hierarchal structure is perceived to be the key channel of tacit knowledge transfer. In the context of inadequate formal sharing channels, officials perceived trainings to be the key formal mechanism of tacit knowledge sharing within public sector organizations in Bangladesh.
