Modulation Of Orientation Research Articles

Orientational Compatibility Modulation of Ligands in Low-Symmetry Multi-Cavity Discrete Coordination Cages by Neighbouring Cage Participation.

Complexation of Pd(II) with a designer unsymmetrical bis-monodentate ligand (2:4 ratio) yielded a specific Pd2L4 type "single-cavity discrete coordination cage" (SCDCC), from a pool of 4 isomeric structures. The observed selctivity is attributed to inherent orientational preference of the ligand strands around the metal centers. Crafting a short coordinating arm at either ends of the bis-monodentate ligand (i.e the longer-arm) produced a pair of unsymmetrical isomeric tris-monodentate ligands; whereas crafting the same short-arm at both ends of the ligand gives an unsymmetrical tetrakis-monodentate ligand. Complexation of Pd(II) with either of the isomeric tris-monodenate ligands (3:4 ratio) resulted in corresponding low-symmetry "multi-cavity discrete coordination cage" MCDCC having two conjoined cavities, though the inherent relative orientational preference of the longer arms is not achievable in these cages. The enforced orientation is sustained by "Neighbouring Cage Participation" (NCP). However, one-pot combination of Pd(II), with a mixture of isomeric tris-monodenate ligands in 3:2:2 ratio produced an integratively self-sorted mixed-ligated MCDCC from a pool of 31 structures. Also, mixing Pd(II) with the tetrakis-monodentate ligand produced a MCDCC having three conjoined cavities. The inherent orientational preference of longer-arm of the ligand strands is retained in the mixed-ligated double-cavity and the homo-ligated triple cavity cages.

Performance of Zigzag Photovoltaic Noise Barriers near a Belgian Highway

Herein, the energy performance of photovoltaic noise barriers (PVNBs) with cassette and shingles built‐on designs is evaluated using imec's energy yield framework. The simulation is validated through on‐site electrical and thermal measurements, and then the same design is employed for a case study near E19 road in Belgium using different scenarios. To optimize the energy yield, variations in the noise barrier height, orientation, and PV module tilt are introduced. The energy yield is then simulated to identify the optimal combination of parameters to maximize energy production. The results show that the cassette built‐on PVNB with fixed cassette distance provides higher energy yield throughout the year compared to other scenarios, and a low‐rise noise barrier is more energy‐efficient due to reduced shading effects. Sound pressure simulation conducted in COMSOL reveals that the cassette built‐on and shingles built‐on have comparable performance in sound reduction, and high‐rise noise barriers with small tilts (20°–40°) are optimal for sound pressure attenuation.

Understanding Iron-Doping Modulating Domain Orientation and Improving the Device Performance of Monolayer Molybdenum Disulfide.

Domain orientation modulation and controlled doping of two-dimensional (2D) transition-metal dichalcogenides (TMDCs) are two pivotal tasks for synthesizing wafer-scale single crystals and boosting device performances. However, realizing two such targets and uncovering internal physical mechanisms remain daunting challenges. We develop an accurate Fe doping strategy, which enables domain orientation control and electron mobility improvement of monolayer MoS2. By tuning of the Fe dopant dosages, parallel steps with different heights are formed, which induce edge-nucleation of unidirectionally aligned monolayer MoS2. In parallel, Fe doping induces the down shift of the conduction band minimum of monolayer MoS2 and matches well with the work function of an electrode, which reduces Schottky barrier height and delivers ultralow contact resistance (561 Ω μm) and excellent electron mobility (37.5 cm2 V-1 s-1). The modulation mechanism is clarified by combining theory calculations and electronic structure characterizations. This work hereby provides a new paradigm for synthesizing wafer-scale 2D TMDC single crystals and constructing high-performance devices.

Task-dependent contribution to edge-based versus region-based texture perception

Texture segregation studies indicate that some types of textures are processed by edge-based and others by region-based mechanisms. However, studies employing nominally edge-based textures have found evidence for region-based processing mechanisms when the task was to detect rather than segregate the textures. Here we investigate directly whether the nature of the task determines if region-based or edge-based mechanisms are involved in texture perception. Stimuli consisted of randomly positioned Gabor micropattern texture arrays with five types of modulation: orientation modulation, orientation variance modulation, luminance modulation, contrast modulation and contrast variance modulation (CVM). There were four modulation frequencies: 0.1, 0.2, 0.4 and 0.8 cpd. Each modulation type was defined by three types of waveforms: sinewave (SN) with its smooth variations, square-wave (SQ) and cusp-wave (CS) with its sharp texture edges. The CS waveform was constructed by removing a sinewave from an equal amplitude square-wave. Participants performed two tasks: detection in which participants selected which of two stimuli contained the modulation and discrimination in which participants indicated which of two textures had a different modulation orientation. Our results indicate that threshold amplitudes in the detection task followed the ordering SQ < SN < CS across all spatial frequencies, consistent with detection being mediated by the overall energy in the stimulus and hence region based. With the discrimination task at low texture spatial frequencies and with CVM textures at all spatial frequencies the order was CS ≤ SQ with both < SN, consistent with being edge-based. We modeled the data by estimating the spatial frequency of a Difference of Gaussian filter that gave the largest peak amplitude response to the data. We found that the peak amplitude was lower for detection than discrimination across all texture types except for the CVM texture. We conclude that task requirements are critical to whether edges or regions underpin texture processing.

Evaluation of education initiatives to increase delivery of age-friendly care in retail clinics.

The Age-Friendly Health Systems model, encompassing four key elements (4Ms)-What Matters, Medication, Mentation, Mobility-is integral to delivering high-quality care to older adult patients. In May 2020, the MinuteClinic at CVS implemented the 4Ms model in all 1100+ store locations nationwide. To prepare healthcare providers to deliver 4Ms care, educational modules were developed to provide an understanding of the gerontology principles that support the 4Ms model of care. Our goal was to evaluate the effectiveness of these education modules on improving reliable 4Ms delivery during retail clinic visits. Educational modules were provided to nurse practitioners and physician associates to complete in a self-directed manner. These included an orientation module with scenarios comparing usual care and 4Ms care, 12 monthly grand rounds focusing on 4Ms case studies, and 10 video vignettes on 4Ms integration. We examined the association between number of education modules completed with the average number of Ms delivered per visit (M-Score) using descriptive statistics and a generalized linear mixed-effects model. Over 70% of 2783 providers completed at least one education module. Rates of 4Ms care delivery were 1.37 (1.36-1.39, p < 0.001) times higher among those that completed an orientation course compared to those that did not. Higher uptake of education exhibited a dose-response relationship with rate ratios between 1.77 (1.74-1.80, p < 0.001) for 1-2 modules beyond orientation, up to 2.94 (2.90-2.99, p < 0.001) for eight or more modules. The self-directed learning environment (e.g., providers self-select the number and type of courses) reflects real-world variation in engagement. Despite this variation, significant improvements in 4Ms delivery were observed at any level of educational exposure, underscoring the value of prioritizing education time with quality improvement initiatives.

Sustainable fabrication of highly (110)-oriented ZIF-8 membrane via supercritical fluid processing

Preferred orientation control represents a crucial step for performance enhancement of MOF membranes. Nevertheless, their sustainable preparation remains a significant challenge. In this work, we fabricated highly (110)-oriented ZIF-8 membranes through supercritical fluid (SCF)-assisted epitaxial growth of oriented seed layer. Benefiting from unique physicochemical properties and intrinsic chemical inertness of supercritical CO2, preferential orientation originated from the seed layer could be well maintained during epitaxial SCF processing; moreover, both unreacted ligands and discharged CO2 could be efficiently recovered, resulting in zero pollutant emission. Our ZIF-8 membrane exhibited ideal C3H6/C3H8 selectivity of 91.8. To the best of our knowledge, this represented the first report of the preparation of highly oriented ZIF-8 membrane with such high C3H6/C3H8 selectivity; more importantly, our study demonstrated that SCF processing represented an effective protocol for orientation modulation of MOF membranes towards superior separations.

Thermal Stability Analysis of Formamidinium–Cesium‐Based Lead Halide Perovskite Solar Cells Fabricated under Air Ambient Conditions

The instability of perovskite solar cells (PSCs) remains a major bottleneck for their commercialization, with thermal instability posing a major concern, given the inevitable presence of heat in photovoltaic devices. Mixed‐cation/halide perovskites demonstrate enhanced stability and efficiency compared to single‐cation/halide perovskites. Identifying the optimal perovskite composition capable of withstanding high temperatures for longer durations is crucial for the development of thermally stable PSCs. This study provides valuable insights into the optimization of mixed‐cation/halide perovskites to enhance the thermal and structural stability of perovskite films. By systematically varying the Cs content in FA1−yCsyPb(I0.85Br0.15)3 (0 &lt; y &lt; 25)‐based perovskite, it is observed that controlling the Cs content allows precise modulation of crystal orientation in perovskite film with 10% Cs obtained as the optimal value. The perovskite film containing 10% Cs not only exhibits reduced microstrain but also demonstrates enhanced thermal stability during testing at 85 °C under controlled humidity. Furthermore, planar PSCs are fabricated using FA0.90Cs0.10Pb(I0.85Br0.15)3 as the absorber layer and TOP‐3 as the hole‐transporting material, achieving a promising power conversion efficiency (PCE) of 17.70%. Impressively, the unencapsulated devices retain 95% of their initial PCE after 1000 h of dark storage under ambient conditions.

Using Drama Pedagogy to Enhance Understanding of HIV Transmission, Infection, and Prevention Among Third-Year Student Teachers

Thirty-eight years into the HIV and AIDS pandemic, the world is still striving to reduce global HIV infections towards zero new infections and AIDS-related deaths by 2030. Sub-Saharan Africa continues to carry the burden of global HIV infections as governmental and nongovernmental agencies try out different prevention strategies (UNAIDS, 2024b). Several scholars have argued that comprehensive sexuality education (CSE) is the best preventive strategy to reach youth and key populations with factual information regarding HIV and AIDS. This paper draws from the project, Mentoring as a Method to Promote Women's Health in the Context of HIV-Prevention and Unequal Gender Relations, which employed memory work, photo-voice, drama, drawings, and focus group discussions with third-year student teachers in a life orientation module. Focussing on the data generated through drama, I present an arts-based activity that was used to teach about HIV transmission to student teachers in a bid to equip them with alternative ways of teaching school-learners about HIV and AIDS. The findings highlight student teachers' lived experiences and how they have shaped their perceptions of HIV infections and living with AIDS. I argue from the findings, that arts-based pedagogies allow for enhanced understanding of complex phenomena due to their participatory and in-built intervention nature. Thus, I posit that pedagogies that employ participatory, arts-based, and visual methodologies should be extensively employed in teacher-education towards reducing new HIV infections among the youth.

Customizing superior surface insulation properties of polymeric dielectric via in-plane molecular chain orientation

Surface flashover is a common breakdown phenomenon on material surfaces for which surface charge migration property, determined by surface composition and molecular chain structure, is crucial. Precise modulation of charge migration property by simple and efficient methods to improve surface flashover voltage is the goal in industry. Here, in-plane molecular chain orientation (MCO) modulation by uniaxial stretching was proposed to achieve this goal and investigate the intrinsic mechanism of charge migration on flashover. Flashover voltage and accompanying leakage current, performed with electrodes oriented at varying angles to the MCO direction, show a consistent trend, which skillfully reveals that the facilitated charge migration is favorable for improving flashover voltage. When the stretching ratio is 3.5, the flashover voltage along the stretching direction (SD) increases by up to 48.7%, while the in-plane minimum flashover voltage remains essentially unchanged with the change in stretching ratio. Molecular chain segment motion properties along different directions further elucidate that the surprising improvement of flashover voltage along SD is primarily due to the MCO that promotes intra-chain charge migration. This work provides a new perspective on anti-flashover modification of polymeric dielectric and will promote the development of surface flashover mechanisms.

Unveiling the Impact of Light-Induced Acceptor-Generated ROS on Device Stability in Organic Photovoltaics.

The intrinsic stability of the acceptor is a crucial component of the photovoltaic device stability. In this study, we investigated the efficiency and stability of the nonfused-ring acceptors LC8 and BC8 under indoor light conditions. Interestingly, we found that devices based on BC8 with terminal side chains exhibited a higher indoor efficiency and stability. Through accelerated aging experiments, we discovered that the acceptors generate singlet oxygen under light exposure with BC8 demonstrating lower levels of ROS compared to LC8. We attribute this difference to the modulation of the acceptor aggregation orientation. Furthermore, the generated reactive oxygen species (ROS) further deteriorate the acceptor structure, and this phenomenon is also observed in high-efficiency acceptor structures, such as Y6. Our research reveals important mechanisms of acceptor photo-oxidation processes, providing a theoretical basis for enhancing the intrinsic stability of acceptors.

Breaking boundaries in radiology: redefining AI diagnostics via raw data ahead of reconstruction

Objective. In the realm of utilizing artificial intelligence (AI) for medical image analysis, the paradigm of ‘signal-image-knowledge’ has remained unchanged. However, the process of ‘signal to image’ inevitably introduces information distortion, ultimately leading to irrecoverable biases in the ‘image to knowledge’ process. Our goal is to skip reconstruction and build a diagnostic model directly from the raw data (signal). Approach. This study focuses on computed tomography (CT) and its raw data (sinogram) as the research subjects. We simulate the real-world process of ‘human-signal-image’ using the workflow ‘CT-simulated data- reconstructed CT,’ and we develop a novel AI predictive model directly targeting raw data (RCTM). This model comprises orientation, spatial, and global analysis modules, embodying the fusion of local to global information extraction from raw data. We selected 1994 patients with retrospective cases of solid lung nodules and modeled different types of data. Main results. We employed predefined radiomic features to assess the diagnostic feature differences caused by reconstruction. The results indicated that approximately 14% of the features had Spearman correlation coefficients below 0.8. These findings suggest that despite the increasing maturity of CT reconstruction algorithms, they still introduce perturbations to diagnostic features. Moreover, our proposed RCTM achieved an area under the curve (AUC) of 0.863 in the diagnosis task, showcasing a comprehensive superiority over models constructed from secondary reconstructed CTs (0.840, 0.822, and 0.825). Additionally, the performance of RCTM closely resembled that of models constructed from original CT scans (0.868, 0.878, and 0.866). Significance. The diagnostic and therapeutic approach directly based on CT raw data can enhance the precision of AI models and the concept of ‘signal-to-image’ can be extended to other types of imaging. AI diagnostic models tailored to raw data offer the potential to disrupt the traditional paradigm of ‘signal-image-knowledge’, opening up new avenues for more accurate medical diagnostics.

Flexible, Biodegradable, and Wireless Magnetoelectric Paper for Simple In Situ Personalization of Bioelectric Implants.

Bioelectronic implants delivering electrical stimulation offer an attractive alternative to traditional pharmaceuticals in electrotherapy. However, achieving simple, rapid, and cost-effective personalization of these implants for customized treatment in unique clinical and physical scenarios presents a substantial challenge. This challenge is further compounded by the need to ensure safety and minimal invasiveness, requiring essential attributes such as flexibility, biocompatibility, lightness, biodegradability, and wireless stimulation capability. Here, a flexible, biodegradable bioelectronic paper with homogeneously distributed wireless stimulation functionality for simple personalization of bioelectronic implants is introduced. The bioelectronic paper synergistically combines i) lead-free magnetoelectric nanoparticles (MENs) that facilitate electrical stimulation in response to external magnetic field and ii) flexible and biodegradable nanofibers (NFs) that enable localization of MENs for high-selectivity stimulation, oxygen/nutrient permeation, cell orientation modulation, and biodegradation rate control. The effectiveness of wireless electrical stimulation in vitro through enhanced neuronal differentiation of neuron-like PC12 cells and the controllability of their microstructural orientation are shown. Also, scalability, design flexibility, and rapid customizability of the bioelectronic paper are shown by creating various 3D macrostructures using simple paper crafting techniques such as cutting and folding. This platform holds promise for simple and rapid personalization of temporary bioelectronic implants for minimally invasive wireless stimulation therapies.

Design and Implementation of the Positioning and Directing Precision Seeder for Cucurbita Ficifolia Seeds

Highlights Identification of large seed plantule point direction were realized using machine vision. A large seed orientation seeder is designed to achieve automatic orientation seeding of large seeds. The directional seeding success (deflection angle of less than 15°) rate was 92.89%. The qualified rate of positioning and orientation reached 87.80% Abstract. A consistent plantule point and a uniform distribution of cucurbit seeds are required for factory seedlings and grafting. However, precision sowing Cucurbita ficifolia seeds automatically with a positioning and orientation method is difficult due to their large, non-spherical shape. To overcome this challenge, a machine vision-based precision seeder was designed specifically for Cucurbita ficifolia seeds. To achieve consistent seed placement and orientation at a 45° angle, a method using machine vision and precise seed positioning and orientation has been proposed. The plantule point location was determined by comparing the pixel values at both ends of seed. The positioning and orientation module was developed to achieve seeding with same orientation of plantule point and located in the center of the plug tray. Finally, the positioning and orientation precision seeder for seeds were tested and evaluated. The results showed that the accuracy rate of seed plantule point identification and the success rate of the seeds orientation actuator were 97.56% and 100.00%. 95.21% of seeds achieved a deflection angle of less than 15°. The germination port of 96.06% of the seeds is distributed in a circle with the center of the hole as the center and a radius of 10 mm. The qualified rate of positioning and orientation reached 87.80%, and the sowing efficiency was about 3750 grains/h. The results showed that the seeder achieves the consistent orientation of the germination port of seeds and sows the seeds in the center of the hole. This finding provides technical support for seedling testing and large-scale factory seedlings.

Analysis of Gaze, Head Orientation, and Joint Attention in Autism With Triadic VR Interviews.

Effective use of gaze and head orientation can strengthen the sense of inclusion in multi-party interactions, including job interviews. Not making significant eye contact with the interlocutors, or not turning towards them, may be interpreted as disinterest, which could worsen job interview outcomes. This study aims to support the situational solo practice of gaze behavior and head orientation using a triadic (three-way) virtual reality (VR) job interview simulation. The system lets users encounter common interview questions and see how they share attention among the interviewers based on their conversational role (speaking or listening). Given the yaw and position readings of the VR headset, we use a machine learning-based approach to analyze head orientations relative to the interviewers in the virtual environment, and achieve low angular error in a low complexity way. We examine the degree to which interviewer backchannels trigger attention shifts or behavioral mirroring and investigate the social modulation of gaze and head orientation for autistic and non-autistic individuals. In both speaking and listening roles, the autistic participants gazed at, and oriented towards the two virtual interviewers less often, and they displayed less behavioral mirroring (mirroring the head turn of one avatar towards another) compared to the non-autistic participants.

Cr-dopant induced crystal orientation and shape modulation in Ni2P nanocrystals for improving electrosynthesis of methanol to formate coupled with hydrogen production

Cr-doped Ni2P nanorods enable a two-electrode overall methanol splitting (OMeS) system, achieving a lowest voltage of 1.16 V to reach a current density of 10 mA cm−2, compared to the cell voltage of 1.65 V for overall water splitting.

EVALUATION OF EDUCATION INITIATIVES TO INCREASE DELIVERY OF AGE-FRIENDLY CARE IN CONVENIENT CARE CLINICS

Abstract The Age-Friendly Health Systems model of care reliably provides four evidence-based elements of high-quality care, to all older adult patients: What Matters, Medications, Mentation, and Mobility (the 4Ms). MinuteClinic at CVS implemented the 4Ms model in all 1100+ locations nationwide in May 2020. To prepare MinuteClinic providers to deliver 4Ms care, educational modules were developed to provide an understanding of the gerontology that supports the 4Ms model of care: an orientation module with two scenarios illustrating the usual care of an older adult patient followed by the same patient receiving 4Ms care, monthly grand rounds (case studies of older adult conditions with the 4Ms), and ten video vignettes regarding integration of 4Ms care. Our goal was to evaluate the effectiveness of these education initiatives, as measured by changes in the mean number of Ms delivered per visit. Over 70% of 3,188 providers completed at least one education module. The rate of 4Ms delivery was 1.7 times higher (p&amp;lt; 0.001) among those completing at least one education module, and 5.7 times higher (p&amp;lt; 0.001) among those completing ten or more modules compared to those who completed none. Each course was associated with significant within subject increases between 10% and 38% in 4Ms delivery in the month following course completion. The self-directed learning environment (e.g., providers self-select into number and type of courses) reflects real-world variation in engagement; despite this variation, improvements in 4Ms delivery were observed at any educational dose, underscoring the value of prioritizing education time with quality improvement initiatives.

NGHIÊN CỨU CHẾ TẠO MÔ ĐUN CHUYỂN HƯỚNG BỨC XẠ LASER BÁN DẪN GHÉP SỢI QUANG 650 NM ỨNG DỤNG TRONG QUANG TRỊ LIỆU VÀ QUANG SINH DIỆT KHUẨN

Currently, diode lasers in the red wavelength region, especially at 650 nm, are extensively utilized in phototherapy and photodynamic inactivation of bacterials by numerous research groups in the field of lasers for biomedical application. These devices offer exceptional advantages, such as their compact size, ease of design and integration, user-friendliness, and high safety for both operators and patients. Among these, fiber-coupled diode lasers provide an efficient solution for delivering radiation from the laser chip to the desired location. However, further optimization is still required for the fabrication technological development of these devices to meet specific application needs. This includes aspects like reducing manufacturing costs, improving component usability during operation, and meeting specialized usage requirements. To develop the technology for device fabrication, addressing the aforementioned demands, we conducted research on the design, fabrication, and characterization of fiber-coupled semiconductor lasers operating at a wavelength of 650 nm. The characterization results demonstrate that the manufactured devices can operate at maximal pumping current of 100 mA and under varying temperatures from 25oC to 40oC. Additionally, a radiation output orientation module has been designed and integrated at the end of the optical fiber to meet various demands in phototherapy and photodynamic inactivation of bacterials.

Pengaruh Program Orientasi Terhadap Tingkat Kecemasan dan Tingkat Kepatuhan Pasien Baru di Ruang Bedah Rumah Sakit X Palangka Raya

New patients to the hospital face anxiety due to changes in environment, illness, financing, health workers, loss of privacy and sense of security. Non-compliance with hospital rules and hospital programs. Anxiety and non-compliance can aggravate major health problems, resulting in changes in physical function, quality of life, medication adherence, poor use of healthcareresources. New patient orientation will adapt the patient to the hospital situation and environment. This study aims to obtain an overview of the effect of the orientation program on the level of anxiety and compliance of new patients in the X Hospital Surgery Room, using the quasi experiment pre-test- post-test method with control group design on 56 respondents divided into control and intervention. Quasi experiment pre-test- post-test method with control group design on 56 respondents divided into control group and intervention group.The study found a decrease in anxiety and an increase in new patient compliance and there was an effect of providing an orientation module for reducing anxiety and increasing new patient compliance in the patient group.The new patient orientation module has a positive effect on reducing new patient anxiety and increasing patient compliance during treatment. The results of this study have implications for nursing services that the orientation program can increase compliance and reduce the anxiety of newly admitted patients. The recommendation of this study is that health care facilities must have a good and structured orientation program to improve the adaptation of new patients to the treatment room environment.
