Sign reversal and symmetry change of anisotropic magnetoresistance in antiferromagnetic LSMO films

The study of anisotropic magnetoresistance (AMR) holds dual significance in both theoretical and applied contexts. The underlying mechanisms of AMR remain unclear, and the phenomenon of AMR sign reversal (positive and negative transitions in values) has garnered multiple interpretations, demanding experimental verification. In this work, the effect of epitaxial strain on magnetic and transport properties of perovskite manganese oxide La0.35Sr0.65MnO3 films is investigated. The AMR demonstrates sign reversal and symmetry change behaviors. The symmetry changes of AMR stem from the competition between Zeeman energy, exchange interaction energy, and magnetocrystalline anisotropy energy. The sign reversal of AMR is attributed to the change in the density of states of spin up and spin down of conduction electrons during the magnetic phase transition induced by epitaxial strain. Our work offers experimental evidence and a reasonable explanation for the origin of the sign reversal of AMR.

Emotional Intelligence and Social Adjustment among Adolescents of Arunachal Pradesh

The capacity to keep track of one's own and other people's feelings and emotions, to recognise differences between them, and to utilise this knowledge to shape one's decisions and behaviour is known as Emotional Intelligence. One definition of adjustment is the process of changing behaviour to achieve harmony with the environment. A healthy connection with society is characterised by a proper awareness of social needs, requirements, and collective objectives as well as a commitment to satisfying the social demands of one's family, peers, culture, and community. Adolescents in our society are presently experiencing a variety of issues at various levels, and it has been determined that their personality disorders are closely related to the causes of these issues. The ultimate purpose of education, according to the current conception of it, is optimum adaptation. The teacher and guidance staff will be better equipped to give pupils with a quality education if knowledge on the adjustment issues of teenage students is available and their wants and feelings are taken into account and understood. The current study assesses the degree and connection between adolescents' Emotional Intelligence and Adjustment. Descriptive Research design has been used for the study. The method of gathering data employed is random sampling. The main conclusions of the current study are that Adolescents' Emotional Intelligence is high, although their degree of Social Adjustment is modest, and that there is a High Correlation between these two variables among the selected samples of Adolescents.

Individualized treatment effects of a digital alcohol intervention and their associations with participant characteristics and engagement.

Conditional average treatment effects are often reported in intervention studies, in which assumptions are made regarding how effects are similar across a heterogeneous sample. Nonetheless, differing factors, such as genetics, age, and sex, can impact an intervention's effect on outcomes. The study aimed to estimate the individualized effects of a digital alcohol intervention among individuals looking online to reduce their drinking. We used data from a randomized controlled trial (RCT), including 2129 adults from the Swedish general population. The RCT concerned a text message-based alcohol intervention that sought to engender change through increasing knowledge on how to change and instilling confidence in changing behaviour. Outcomes were total weekly alcohol consumption and monthly heavy episodic drinking. Individualized treatment effects were modelled using baseline characteristics (age, gender, alcohol consumption, and psychosocial variables) and engagement with the intervention content. We found evidence that the effects of the digital alcohol intervention were heterogeneous concerning participants' age, baseline alcohol consumption, confidence, and importance. For heavy episodic drinking, there was evidence that effects were heterogeneous concerning age, sex, and baseline alcohol consumption. Overall, women, older individuals, and heavier drinkers benefitted more from the intervention in terms of effect size. In addition, participants who engaged more with the goal-setting and screening content reported better outcomes. The results highlight how different individuals respond differently to a digital alcohol intervention. This allows insight into who benefits the most and least from the intervention and highlights the potential merit of designing interventions adapted to different individuals' needs.

Climate change beliefs and behaviours: Data collected from 30-year-old offspring and their parents in the Avon Longitudinal Study of Parents and Children (ALSPAC)

Climate change is causing a suite of environmental and social issues. Understanding patterns of climate change beliefs and behaviours, and the factors which shape these attitudes and actions, is therefore essential. This data note describes the novel data collection of climate belief and behaviour questions embedded within the Avon Longitudinal Study of Parents and Children (ALSPAC), a longitudinal population-based birth cohort in southwest England. Two generations of ALSPAC participants completed the questionnaires containing these climate questions: the Generation-1 (G1) offspring (n=4,341), Generation-0 (G0) mothers (n=4,793), and the G0 mother’s partners (n=2,111). The questions asked about: belief in climate change; concern over climate change; whether climate change is caused by human activity; whether individual behaviours can impact climate change; the impacts of climate change in the participants’ local area; and whether participants were engaging in any of 17 pro-environmental behaviours (e.g., recycling more, reducing meat/dairy consumption) for climate change and/or other reasons. The majority of participants believed the climate was definitely changing (~80%), were somewhat or very concerned about climate change (~90%) and attributed most or all of climate change to human activity (~75%), with only small differences between the generations. On average, participants reported engaging in between 5 and 6 actions because of concerns regarding climate change (5.8 in G0 mothers; 5.2 in G1 offspring and G0 partners). Associations with sociodemographic factors (e.g., age, sex, ethnicity and socioeconomic background) were relatively weak, but positive relationships between highest level of education and greater climate change belief, concern and behaviours were evident. Increased climate belief and concern also predicted engaging in more pro-environmental actions. Responses to these climate questions were more similar within-families. This data note provides important information for future users of these data, as well as discussing some of the key strengths, limitations and considerations for data users.

Effects of Fe substitution for Mn on structural, magnetic and magnetocaloric properties of TbMn2-xFexSi2

The structural and magnetic properties of TbMn2-xFexSi2 compounds (x = 0.0–0.4) have been investigated in details by high-resolution synchrotron x-ray and neutron powder diffraction, specific heat, and dc magnetization measurements. The replacement of Fe for Mn in TbMn2-xFexSi2 does not change the crystal structure but leads to a significant contraction of the unit cell (dV/dx ∼ - 6 Å3) and modification of three magnetic phase transition temperatures – the Curie temperatures Tc1, Tc2 and the Néel temperature TN. For example, the Tc1, Tc2 and TN values of TbMn2Si2 decrease from Tc1 = 50 K, Tc2 = 64 K and TN = 500 K to Tc1 = 27 K, Tc2 = 37 K and TN = 440 K for TbMn1.6Fe0.4Si2. Detailed neutron diffraction investigations have allowed us to determine the magnetic structures and construct the magnetic phase diagram as well as confirm the presence of magnetoelastic coupling effects. The significantly different responses of Tc1 and Tc2 to applied magnetic fields (e.g. dTc1/dB = 0.52 K/T and dTc2/dB = 4.7 K/T for TbMn1.6Fe0.4Si2), leads to expansion of the temperature region (ΔT = Tc2- Tc1) for the canted ferromagnetic state Fmc-ii between Tc1 and Tc2. In the case of TbMn1.6Fe0.4Si2, ΔT increases from ΔT = 9 K for applied magnetic field B = 0.2 T to ΔT = 36 K for B = 6 T, resulting in plateau-like behaviour of magnetic entropy change and enhances the relative cooling power (RCP) in this system. Under a change of magnetic field of 0 T – 5 T, the maximum value of the magnetic entropy changes -ΔSmax and adiabatic temperature change, ΔTad are derived to be -ΔSmax = 13.1 J/kg K and ΔTad = 8.4 K with the RCP = 411 J/kg for x=0.4 sample. The plateau-like magnetocaloric effect and relatively large RCP make these materials potentially suitable for application in cryogenic magnetic refrigeration.

Penguatan Peran Orang yang Dianggap Penting dalam Penerapan Gizi Seimbang pada Remaja di Tohudan Wetan Colomadu

Adolescents in Tohudan Wetan have insufficient knowledge about balanced nutrition. Teenagers often do not pay attention to the nutritional intake they consume and like to eat fast food. Teenagers also often follow trends in the type of food they consume. This service aims to provide information to teenagers about healthy food, balanced nutrition, the benefits of consuming balanced nutritious food, and the impact of consuming junk food. This service will be carried out online in 2021. The targets of this service are 15 teenagers and 3 friends who are considered important by the 15 teenagers. This activity was carried out by providing information regarding types of healthy food as well as giving messages to three people who were considered important by teenagers to inform and remind teenagers to continue consuming balanced nutritious food. Through education and strengthening the role of people who are considered important in implementing balanced nutrition, the results showed that there was an increase in teenagers' knowledge regarding balanced nutritional consumption patterns and there were teenagers who succeeded in reducing their consumption of unhealthy foods such as junk food. The importance of support from people who are considered important makes them more committed to changing behavior because the support of friends becomes a reinforcing factor for behavior change.

Thermal Energy Storage in Concrete by Encapsulation of a Nano-Additivated Phase Change Material in Lightweight Aggregates.

This work discusses the applicability of lightweight aggregate-encapsulated n-octadecane with 1.0 wt.% of Cu nanoparticles, for enhanced thermal comfort in buildings by providing thermal energy storage functionality to no-fines concrete. A straightforward two-step procedure (impregnation and occlusion) for the encapsulation of the nano-additivated phase change material in lightweight aggregates is presented. Encapsulation efficiencies of 30-40% are achieved. Phase change behavior is consistent across cycles. Cu nanoparticles provide nucleation points for phase change and increase the rate of progression of phase change fronts due to the enhancement in the effective thermal conductivity of n-octadecane. The effective thermal conductivity of the composites remains like that of regular lightweight aggregates and can still fulfil thermal insulation requirements. The thermal response of no-fines concrete blocks prepared with these new aggregates is also studied. Under artificial sunlight, with a standard 1000 W·m-2 irradiance and AM1.5G filter, concrete samples with the epoxy-coated aggregate-encapsulated n-octadecane-based dispersion of Cu nanoparticles (with a phase change material content below 8% of the total concrete mass) can effectively maintain a significant 5 °C difference between irradiated and non-irradiated sides of the block for ca. 30 min.

Systematic review and narrative synthesis of the experiences of individuals with chronic pain participating in digital pain management interventions.

The use of digital pain management interventions has grown since the Covid 19 pandemic. The aim of this study was to systematically review and synthesise evidence from qualitative studies regarding the experiences of individuals with chronic pain participating in digital pain management interventions in primary care and community settings. Fourteen databases were searched, as well as citation tracking and hand-searching reference lists of included articles. The latest search was completed by 07/07/2023. Qualitative studies of patient and carer perspectives of digital pain management interventions for adults aged 18 and over with non-malignant chronic pain were included. All studies were appraised for quality using the Critical Appraisal Skills Programme Qualitative Checklist. A narrative synthesis approach was used to synthesise the findings. Normalisation Process Theory was used to understand how individuals with chronic pain make sense of digital pain management interventions and incorporate knowledge, skills and strategies learnt into their day-to-day lives. Eleven studies, encompassing both digital applications for use on smartphones/ mobile devices and user-directed online modular programmes, were included in the synthesis. Three main themes and related subthemes were identified from the included studies: 1) Making sense of the digital intervention (Subthemes: Tailoring to user's needs; Human contact and support; Accessibility of the digital intervention; Personal and environmental factors affecting engagement with digital interventions); 2) Initiating and Maintaining Behaviour Change (Subthemes: Planning activity; Being active); and 3) Personal Growth (Subthemes: Gaining understanding and skills; Gaining and acting on feedback; Negotiating a new relationship with pain). Recommendations. The key recommendations from our findings are that digital pain management interventions should provide: Specific and tailored information for individual participants.Focus on changing attitudes and behaviours and reframing perceptions of pain.Structured goal setting with prompts to review goals.Potential healthcare professional support alongside the digital intervention.Limitations of the review. To reduce bias, it would have been preferable for more than one author to independently fully analyse each paper and to identify themes and sub-themes. Instead, the identified themes and sub-themes were discussed with two other authors in the team (ES, LW) to reach a consensus view on final themes and sub-themes. One author (JS) received a Research Internship and Research Initiation Award funded by NIHR Applied Research Collaboration (ARC) Wessex (https://www.arc-wx.nihr.ac.uk/) and NHS England (https://www.england.nhs.uk/). The protocol for this review was registered with the National Institute of Health Research (NIHR) PROSPERO international database for registering systematic reviews (PROSPERO Registration Number CRD42021257768).

Opposing positions, dividing interactions, and hostile affect: A systematic review and conceptualization of “online climate change polarization”

AbstractOnline climate change polarization has increasingly received academic interest over time. Online media facilitate and accelerate processes of climate change polarization. Yet, throughout the years, online climate change polarization became a fuzzy concept, holding different meanings in different academic contexts. By reviewing the available evidence, the current article identified three ontological distinctions in online climate change polarization research: (1) focus on different groups that polarize; (2) either investigate the positions, relations, or emotions of actors; and (3) states or processes of polarization. Based on the latter two ontological distinctions, the article reconceptualizes online climate change polarization as a multidimensional phenomenon, by introducing a framework comprising six dimensions of polarization. Accordingly, by identifying gaps in the literature, the article proposes a future research agenda.This article is categorized under: Perceptions, Behavior, and Communication of Climate Change > Communication Perceptions, Behavior, and Communication of Climate Change > Perceptions of Climate Change Perceptions, Behavior, and Communication of Climate Change > Behavior Change and Responses

Humidity sensitive memristor based on Ni–Al layered double hydroxides

Reaping the advantages of their exceptional humidity-sensitive elements, humidity sensors exhibit a remarkable ability to adapt to alterations in ambient moisture levels. The significance of the humidity sensor in biological detection is progressively growing, owing to this characteristic. This work examines the impact of humidity on the resistive switching properties Ni–Al layered double hydroxides (LDHs) memristor. As the porous Ni–Al LDHs material contains a significant number of hydroxyl groups, the Ni–Al LDHs memristor exhibits remarkable sensitivity to changes in humidity. As the relative humidity level increases, a conspicuous decrease is observed in resistance of low resistance state, which attributed to the transition of protons facilitated by water. The humidity detection range of the Ni–Al LDHs memristor is from 30 RH% to 95 RH%, and it exhibits a sensitivity of 101.72 mV/RH. The Ni–Al LDHs memristor exhibits humidity sensitive resistive switching characteristics. In different humidity environments can produce a dynamic change between high and low resistance state switching. An artificial humidity sensing system by utilizing the unique resistance change behavior in Ni–Al LDHs memristor induced by humidity was demonstrated.

Influence of rainfall changes from 4.6 to 3.0 ka BP on ceramic pipes

The impact of climate change on human social development has been a topic of research for a long time. Ceramic pipes, which are vital components of urban drainage engineering, are crucial means of managing rain hazards and floods. Exploring the historical evolution of ceramic pipes can help in better understanding the interplay between climate change and human behavior. This study examined the diameters of 86 ceramic pipes unearthed from six cultural sites in central China, including Pingliangtai, Taosi, and Erlitou, dated to 4600–3040 a BP. By combining speleothem records from the excavation sites with precipitation and temperature composite curves for China using Pearson correlation analysis, and verifying with pollen records. The results show that changes in rainfall were the main factor influencing the diameters of the ceramic pipes. This indicates that during this period, ancient people in the Central Plains of China were able to adjust the size of the ceramic pipes to regulate the water management capacity of urban water systems, thereby adapting urban development to climate change.

Diagnosing and managing prescription opioid use disorder in patients prescribed opioids for chronic pain in Australian general practice settings: a qualitative study using the theory of Planned Behaviour

BackgroundChronic pain is a debilitating and common health issue. General Practitioners (GPs) often prescribe opioids to treat chronic pain, despite limited evidence of benefit and increasing evidence of harms, including prescription Opioid Use Disorder (pOUD). Australian GPs are worried about the harms of long-term opioids, but few are involved in the treatment of pOUD. There is little research on GPs’ experiences diagnosing and managing pOUD in their chronic pain patients.MethodsThis qualitative research used semi-structured interviews and a case study to investigate GPs’ experiences through the lens of the Theory of Planned Behaviour (TPB). TPB describes three factors, an individual’s perceived beliefs/attitudes, perceived social norms and perceived behavioural controls. Participants were interviewed via an online video conferencing platform. Interviews were transcribed verbatim and thematically analysed.ResultsTwenty-four GPs took part. Participants were aware of the complex presentations for chronic pain patients and concerned about long-term opioid use. Their approach was holistic, but they had limited understanding of pOUD diagnosis and suggested that pOUD had only one treatment: Opioid Agonist Treatment (OAT). Participants felt uncomfortable prescribing opioids and were fearful of difficult, conflictual conversations with patients about the possibility of pOUD. This led to avoidance and negative attitudes towards diagnosing pOUD. There were few positive social norms, few colleagues diagnosed or managed pOUD. Participants reported that their colleagues only offered positive support as this would allow them to avoid managing pOUD themselves, while patients and other staff were often unsupportive. Negative behavioural controls were common with low levels of knowledge, skill, professional supports, inadequate time and remuneration described by many participants. They felt OAT was not core general practice and required specialist management. This dichotomous approach was reflected in their views that the health system only supported treatment for chronic pain or pOUD, not both conditions.ConclusionsNegative beliefs, negative social norms and negative behavioural controls decreased individual behavioural intention for this group of GPs. Diagnosing and managing pOUD in chronic pain patients prescribed opioids was perceived as difficult and unsupported. Interventions to change behaviour must address negative perceptions in order to lead to more positive intentions to engage in the management of pOUD.

Beyond social influence: Examining the efficacy of non-social recommendations

Do recommendations need to contain social information to change behaviour in allocation and risk tasks? We conducted two online experiments involving 1280 participants to compare the behavioural influence of recommendations based on normatively relevant information with that of recommendations that were transparently random. Although social recommendations generally shifted choices towards the recommended option, consistent with previous studies on norm compliance, their effects were statistically indistinguishable from those of random recommendations. This finding challenges the notion that norm compliance is the sole mechanism through which social recommendations exert their influence. In a follow-up study with 481 participants, we investigated four additional channels. Our results suggest that recommendations do not act as reminders of existing normative knowledge, but we find evidence partially consistent with recommendation following in order to deflect responsibility, because of an anchoring effect, and because of a social norm to follow recommendations.

Spinal histamine H4 receptor mediates chronic pruritus via p-ERK in acetone-ether-water (AEW)-induced dry skin mice.

Dry skin is common to many pruritic diseases and is difficult to improve with oral traditional antihistamines. Recently, increasing evidence indicated that histamine H4 receptor (H4R) plays an important role in the occurrence and development of pruritus. Extracellular signal-regulated kinase (ERK) phosphorylation activation in the spinal cord mediates histamine-induced acute and choric itch. However, whether the histamine H4 receptor regulates ERK activation in the dry skin itch remains unclear. In the study, we explore the role of the histamine H4 receptor and p-ERK in the spinal cord in a dry skin mouse model induced by acetone-ether-water (AEW). q-PCR, Western blot, pharmacology and immunofluorescence were applied in the study. We established a dry skin itch model by repeated application of AEW on the nape of neck in mice. The AEW mice showed typically dry skin histological change and persistent spontaneous scratching behaviour. Histamine H4 receptor, instead of histamine H1 receptor, mediated spontaneous scratching behaviour in AEW mice. Moreover, c-Fos and p-ERK expression in the spinal cord neurons were increased and co-labelled with GRPR-positive neurons in AEW mice. Furthermore, H4R agonist 4-methyhistamine dihydrochloride (4-MH)induced itch. Both 4-MH-induced itch and the spontaneous itch in AEW mice were blocked by p-ERK inhibitor U0126. Finally, intrathecal H4R receptor antagonist JNJ7777120 inhibited spinal p-ERK expression in AEW mice. Our results indicated that spinal H4R mediates itch via ERK activation in the AEW-induced dry skin mice.

Quasiparticles-mediated thermal diode effect in Weyl Josephson junctions

We theoretically show quasiparticles-driven thermal diode effect (TDE) in an inversion symmetry-broken Weyl superconductor (WSC)-Weyl semimetal (WSM)-WSC Josephson junction. A Zeeman field perpendicular to the WSM region of the thermally-biased Weyl Josephson junction (WJJ) induces an asymmetry between the forward and reverse thermal currents, which is responsible for the TDE. Most interestingly, we show that the sign and magnitude of the thermal diode rectification coefficient is highly tunable by the superconducting phase difference and external Zeeman field, and also strongly depends on the junction length. The tunability of the rectification, particularly, the sign changing behavior associated with higher rectification enhances the potential of our WJJ thermal diode to use as functional switching components in thermal devices.

THE ONTOLOGY OF NETWORK WARFARE: THE ESSENCE AND CONSEQUENCES

The constitution of a new space for the functioning of social reality due to the impact of information and communication technologies on all spheres of human activity contributed to the transformation of traditional military operations, which resulted in the spread of network wars. The networking and digitalization of society has led to a change in human existence. Cognitive, informational, social, and psychological aspects of network processes form a new picture of the world, creating conditions for changing people's mentality and behavior. Therefore, the identification of the ontological foundations of network warfare is of particular importance. The disclosure of its essence is a prerequisite for the development of measures to preserve the security of the statedevelopment. The transformation of the mechanism of datainformational impact on the consciousness and meaning of both an individual and large social groups has led to a change in the civic position of the individual, expanding the possibilities for manipulating public opinion. The formation of new network structures and the spread of cyberterrorism are modifying the world order. Network wars have become an integral phenomenon of the modern realityexistence. Their attribute, which determines the specifics of the conflict unfolding, is the destructive use of information. Information disseminated on the Internet forms social content. Thus, new conditions are being created for the aggravation of contradictions, including the world community in the zone of confrontation, manipulating the behavior of its representatives, creating opportunities for non-contact warfare.

Developing a dynamic life cycle assessment framework for buildings through integrating building information modeling and building energy modeling program

The construction and building sector is one of the largest contributors to the global carbon emissions. Therefore, it is imperative to accurately assess the carbon emissions of buildings throughout the life cycle. Many studies conducted life cycle assessment (LCA) of buildings to evaluate carbon emissions. However, due to the lack of dynamic data, most studies adopted the static LCA methodology, which neglected the dynamic variations during life cycle stages of a building. Unlike previous studies that collected static data from questionnaires and documents, the present study aims to establish a novel dynamic life cycle assessment (D-LCA) framework for buildings by incorporating the building information modeling (BIM) and the building energy modeling program (BEMP) into the static LCA. First, a static LCA is established as the baseline scenario that covers the “cradle-to-grave” life cycle stages. A BIM model is established using Revit to obtain the inventory of building materials. The Designer Simulation Toolkit (DeST) is used as a BEMP to simulate the operating energy consumption of the studied building, taking into account changes in energy mix, climate change, and occupant behavior. At the same time, the DeST results are further used as a data input for dynamic scenarios. The D-LCA framework is applied to a high-rise commercial building in China. This study found that the difference between static and dynamic scenarios was up to 66.7 %, mainly reflected in the dynamic energy consumption during the operation phase, indicating the inaccuracy of traditional static LCA. Therefore, a D-LCA by integrating BIM and BEMP can facilitate dynamic modeling and improve the accuracy and reliability of LCA for buildings.
