Best-practices for co-design processes involving people with severe mental illness for eMental health interventions: a qualitative multi-method approach

Abstract The lack of adoption of eMental Health technologies by people with severe mental illness (SMI) might be explained by a mismatch between technology design and users’ skills, context and preferences. Co-design can optimize this fit, but populations labelled as ‘vulnerable’ are often excluded or misrepresented. The goal of this study is to gain insight into best-practices for co-design with people with SMI. A qualitative, multi-method approach was used, consisting of a systematic scoping review of 21 included studies, 25 co-design expert surveys and six participant interviews. The results delivered 23 best-practices divided into four overarching aspects of co-design, namely: (1) activities to carry out before the start of a co-design study; (2) fruitful collaboration of the co-design team; (3) bespoke approach within co-design to accommodate the skills and abilities of SMI participants; and (4) mitigation of challenges surrounding power balance. The best-practices may help researchers and designers offer the SMI population a more specialized approach for co-design, which can cause the innovative output of eMH projects to be more effective and better adopted. Throughout the co-design process, more attention should be paid to the personal and clinical benefits of participation for the participants themselves.
Phytoplankton Composition and Abundance in Mbiakong River, Cross River Estuary, Niger Delta, Nigeria

The phytoplankton composition and abundance in Mbiakong River, Cross river estuary, Niger Delta, Nigeria was studied for a period of one year (March, 2021-February, 2022). Plankton net of mesh size 55µm was used to collect plankton samples from below the water surface, after towing for 5 minutes. The content was emptied into plastic containers and fixed immediately with 4% formalin in the field for preservation. After 48hrs in the laboratory, the preserved plankton samples were concentrated to 10 ml. The concentrated sample was agitated to homogenize before pipetting 1ml sub sample with sample pipette. Enumeration and identification were performed using a zeis inverted microscope at x400 and x 1000 magnification. Species identification was done using recommended keys and guides. A total of six hundred and fifteen (615) individual organisms comprising of thirty-five (35) species belonging to five (5) taxonomic groups were recorded from Mbiakong River. The most abundant group was the Bacillariophyceae which was represented by 12 species (302 organisms) consisting of 49.11%. This was followed by Chlorophyceae represented by 10 species (199 organisms) consisting of 32.36%, Cyanophyceae represented by 12 species (109 organisms) consisting of 17.72%, Euglenophyceae represented by 1 species (3 organisms) consisting of 0.33% and the least abundant was the Dinophyceae represented by 1 species (2 organisms) consisting of 0.14%. The study revealed that species composition and abundance was high in June.
Extended tail states in an imaginary random potential

The tail eigenstates, having an anomalously small real part of energy Re({epsilon}) are considered for the non-Hermitian disordered Hamiltonian with an imaginary random potential. Unlike in the case of Hermitian quantum mechanics, our tail states are extended over a parametrically large region. Such states appear if the values of the random potential accidentally happens to be anomalously close inside the region. Analytical results for the density of tail states are confirmed by numerical simulations.

Vertical directionality and depth dependence of averaged acoustic signals and noise

The vertical directionality of an averaged acoustic field is shown in theory to depend on the depth at which it is observed in a special way. The result is based on a simple angle transformation, and is limited by the assumption that the field is a superposition of independent plane‐wave components which obey Snell’s law for a stratified medium near the receiver location. The approach applies to both transmission loss and ambient noise, and is used to derive a relationship between the directionality at a single depth and the depth dependence of the total (omnidirectional) intensity. Examples show the influence of the local sound–speed profile and illustrate sensitivities in the relationship for special cases. Implications for measurement strategies, data interpretation, and predictive modeling are discussed.
Three-stage fusion framework for single image dehazing

Abstract. Fog generally causes loss or blurring of image information, significantly affecting work and life. This study proposes a three-stage fusion method comprising multiscale dark channel image fusion based on the dark channel prior, multiexposure image fusion using a gamma-correction technique, and a final fusion combining the restoration-based and enhancement-based methods to ensure good saturation and contrast in the dehazing result. The proposed method is experimentally evaluated in detail, and qualitative as well as quantitative analyses are performed. The obtained results indicate that our method can effectively improve the haze removal performance and is advantageous for dealing with long-distance hazy images.
Ecological studies on the helminth parasites of catfishes Bagrus spp. (Bagridae) and Chrysichthys auratus (Claroteidae) inhabiting Damietta branch, River Nile, Egypt

ABSTRACT The results of a survey on the helminth parasites of the catfishes Bagrus spp. Forsskål, 1775 and Chrysichthys auratus Geoffroy,1809 inhabiting Damietta branch of the River Nile at Mansoura city, Dakahlia Governorate, Egypt, have been demonstrated. During the period of March 2020 to February 2021, five species were detected from Bagrus spp. and represented by one monogenean Quadriacanthus bagrae from the gills, three digeneans Acanthostomum absconditum, Acanthostomum spiniceps and Haplorchoides cahirinus and a single nematode species Capillostrongyloides fritschi from the intestine. Only one monogenean species Protoancylodiscoides mansourensis was detected from the gills of Chrysichthys auratus. Except for a few months, most monogeneans, digeneans and nematodes of Bagrus spp. and C. auratus were recorded in all months of the year. The digeneans A. absconditum, A. spinicips, and H. cahirinus are eudominant and A. absconditum was the most dominant while the nematode C. fritschi is subrecedent. In Bagrus spp. , the digenean parasites attained the highest prevalence over the monogeneans and nematode parasites throughout the year (77.7%). There was a definite seasonal change in the studied helminths, but no general common trend or pattern was observed. Most helminth parasites showed a higher prevalence in male fishes than females while they attained a higher abundance in females than males. There was a significant difference in the mean prevalence as well as in the mean intensity of most examined parasite species in male fishes and females but a significant difference in the mean abundance of males and females was only recorded for the digenean parasites. Most parasites showed a higher prevalence as the condition factor of the host increased.
Antibacterial Coatings for Titanium Implants: Recent Trends and Future Perspectives

Titanium and its alloys are widely used as implant materials for biomedical devices owing to their high mechanical strength, biocompatibility, and corrosion resistance. However, there is a significant rise in implant-associated infections (IAIs) leading to revision surgeries, which are more complicated than the original replacement surgery. To reduce the risk of infections, numerous antibacterial agents, e.g., bioactive compounds, metal ions, nanoparticles, antimicrobial peptides, polymers, etc., have been incorporated on the surface of the titanium implant. Various coating methods and surface modification techniques, e.g., micro-arc oxidation (MAO), layer-by-layer (LbL) assembly, plasma electrolytic oxidation (PEO), anodization, magnetron sputtering, and spin coating, are exploited in the race to create a biocompatible, antibacterial titanium implant surface that can simultaneously promote tissue integration around the implant. The nature and surface morphology of implant coatings play an important role in bacterial inhibition and drug delivery. Surface modification of titanium implants with nanostructured materials, such as titanium nanotubes, enhances bone regeneration. Antimicrobial peptides loaded with antibiotics help to achieve sustained drug release and reduce the risk of antibiotic resistance. Additive manufacturing of patient-specific porous titanium implants will have a clear future direction in the development of antimicrobial titanium implants. In this review, a brief overview of the different types of coatings that are used to prevent implant-associated infections and the applications of 3D printing in the development of antibacterial titanium implants is presented.
Sensitivity enhanced long-period grating refractive index sensor with refractive index modified cladding layer

A sensitivity enhanced long-period grating (LPG) refractive index sensor is proposed and studied by using the LP model. In the simulation, the cladding layer of the LPG is assumed to be partially removed and then deposit a sensitivity enhancement layer (SEL) with a higher refractive index. The effects of the thickness of the original cladding material, and the thickness and refractive index of the SEL layer on the LPG transmission spectrum notch wavelength shift as a function of the ambient refractive index change are reported. The LPG sensor performance depends on the phase match condition of the core mode and cladding mode coupling in the LPG structure and the dependence of the effective index of the cladding mode on the thickness of the original cladding material, and the thickness and refractive index of the SEL layer. The structure modified cladding layer moves the work point of the long period grating to the cladding mode reorganization zone, where the cladding mode effective refractive index changes rapidly upon the LPG waveguide parameter. Proper selection of parameters of the cladding layer can be applied to enhance the modulation of the effective index of the cladding mode by the ambient refractive index through the evanescent field and thus construct sensitivity enhanced ambient refractive index sensors.
The LOFT Attack: Overflowing SDN Flow Tables at a Low Rate

The emerging Software-Defined Networking (SDN) is being adopted by data centers and cloud service providers to enable flexible control. Meanwhile, the current SDN design brings new vulnerabilities. In this paper, we explore a stealthy attack that uses a minimum rate of attack packets to disrupt SDN data plane. To achieve this, we propose the LOFT attack that computes the lower bound of attack rate to overflow flow tables based on the inferred network configurations. Particularly, each attack packet always triggers or maintains consumption of one flow rule. LOFT can ensure the attack effect under various network configurations while reducing the possibility of being captured. We demonstrate its feasibility and effectiveness in a real SDN testbed consisting of commercial hardware switches. The experimental results show that LOFT incurs significant network performance degradation and potential network DoS at an attack rate of only tens of Kbps. To defeat the attack, we develop a data-to-control plane collaborative defense system named LOFTGuard, which is lightweight and transparent to SDN applications. Evaluations show that LOFTGuard effectively protects SDN against the attack and introduces a small overhead.
Excitonic characteristics in direct wide-band-gap CuScO2 epitaxial thin films

Thin films of a delafossite compound CuScO2 were grown on spinel MgAl2O4 (111) substrates, yielding in highly crystalline and (0001)-oriented epitaxial structures. Absorption spectra at 20 K revealed a sharp exciton resonance at 3.97 eV, which persisted up to 300 K. Its direct transition band gap at 20 K and exciton binding energies were determined to be about 4.35 and 380 meV, both of which are considerably larger than those of ZnO. In view of its capability of naturally layered structure and p-type doping, this compound will be interesting for exciton physics as well as implementation of heterostructured devices.
Assessment of Tear Meniscus Dimensions Using Anterior Segment Optical Coherence Tomography in Vitamin D Deficiency in a Pediatric Population

Abstract Background To investigate of the effect of vitamin D (Vit-D) deficiency on the tear film in children and compare it with that of healthy subjects. Methods This prospective and cross-sectional study comprised 75 eyes of children who had Vit-D deficiency (Group 1) and 85 eyes of age- and gender-matched healthy children (Group 2). The tear-film break-up time (TF-BUT) and Schirmer test values, as well as the Ocular Surface Disease Index (OSDI) scores, were recorded for the participants in all groups. Measurement of the tear meniscus area (TMA) and tear meniscus height (TMH) was performed 2 times in the same day via the use of anterior segment-optical coherence tomography (AS-OCT). Results The mean age of the participants in Group 1 was 12.42 ± 3.40 years, while in Group 2, it was 12.59 ± 2.32 years (p = 0.758). Group 1 comprised 43 females and 32 males, while Group 2 comprised 44 females and 41 males (p = 0.250). The mean TMH, TMA, and Schirmer test values were found to be significantly lower in children with Vit-D deficiency (Group 1) than in healthy children (Group 2), with p < 0.05 for all the values. It was concluded that there was no significant difference in the values for the mean TF-BUT and OSDI scores (p = 0.029 and p = 0.596, respectively). Conclusion The children with Vit-D deficiency exhibited lower TMH, TMA, and Schirmer test values. The alterations that were observed in these parameters were more prominent in the participants who had lower Vit-D levels.
Enhancement effect of terahertz wave in split ring resonators

Based on the theory of split ring resonators (SRRs) and the rigorous theory of electromagnetic field, the spatial distributions of the electric field and electric energy density in split ring resonators with different structures such as square, circle and triangle have been analyzed. The variation of electric energy density with different terahertz (THz) frequencies has also been investigated. It can be shown from our numerical simulation results that the electric field enhancement effect occurs in the split ring resonators with square, circle and triangle structures and the electric field near the opening is obviously stronger than that in other regions, especially in the gap of the split ring resonators. The maximum of the electric energy density appears in the opening of the SRRs and the electric field is obviously stronger near the resonance frequency of the SRRs. The results obtained in this paper have important significance on the design of the split ring resonators and the function of resonant magnetic response of left hand materials (LHMs).
A Bernasconi model for constructing ground-state spin systems and optimal binary sequences

A Bernasconi model for a one-dimensional chain of quantum particles is considered. It is shown that searching for the ground state of such a quantum system is equivalent to searching for optimal binary sequences with minimum energy levels. The second criteria for the optimality of binary sequences with low levels of aperiodic autocorrelation is the minimax criterion, in which the peak level of side lobe (PSL) must be minimal. A review and new results regarding the construction of such binary sequences up to length N=82 are presented.
Dormitory neighbourhood: the role of studentification in developing low-quality neighbourhood, case of Babolsar, Iran

ABSTRACT Studentification studies in different contexts have reported diverse impacts on urban areas. The conceptualization of the phenomenon is generally based on experiences from developed countries, while studies in developing contexts are scarce. This research explores a neighbourhood in Babolsar, Iran, where studentification has motivated the transformation of agricultural fields around the University of Mazandaran campus into a residential neighbourhood with a concentration of student accommodation. The mixed method approach shows that the economic and policy background has directly influenced low quality developments of built environment, public spaces and facilities compared to rest of the town. As a result, what we call a ‘Dormitory Neighbourhood’ is shaped around the campus, extending a dormitory’s characteristics into an urban area. Originated from Babolsar context, a dormitory neighbourhood shows to facilitate several processes of urban decline to emerge and evolve in the absence of effective urban development policy.
Need satisfaction and collective efficacy in undergraduate blog-driven classes: A structural equation modelling approach

This paper investigates how psychological needs spurring self-determined motivation relate to collective efficacy for flourishing in online learning communities. Self-determination theory posits individuals experience intrinsic motivation to flourish at educational tasks because of targeted satisfaction of the three psychological needs: autonomy, relatedness, and competence. However, studies conducted to investigate collective, technology-assisted learning processes suggest competence and relatedness may play a pivotal role in online community engagement and knowledge-sharing. Moreover, informal gaming experiences may mirror the collaborative skills needed in online educational/professional communities. These insights suggest confidence in one’s abilities to contribute to a community, the perception of a strong, supportive social culture in the online classroom, and informal online experiences may lead to self-determined motivation enabling agents in distributed, technology-assisted classrooms to collectively flourish. Little work has been done to examine effects of need satisfaction on collective efficacy in using online technologies. To fill this research gap, we used structural equation modelling to investigate perceptions of 636 undergraduate students enrolled in classes within an education department at a midwestern university employing weekly asynchronous blogging. Our results suggest students’ experience with multiplayer gaming, and need satisfaction towards competence and relatedness correlate with higher collective efficacy in technology-assisted classrooms employing discussion forums. Implications for practice or policy: For instructors, student usership and design can spur motivation in online classrooms. For researchers, understanding student perceptions of collaboration using technology can help understand how to design better technology-assisted classrooms. The design of collaborative online educational communities should focus on creating positive social cultures and fostering competence for students.
