Progress of Polymer-Based Thermally Conductive Materials by Fused Filament Fabrication: A Comprehensive Review

With the miniaturization and integration of electronic products, the heat dissipation efficiency of electronic equipment needs to be further improved. Notably, polymer materials are a choice for electronic equipment matrices because of their advantages of low cost and wide application availability. However, the thermal conductivity of polymers is insufficient to meet heat dissipation requirements, and their improvements remain challenging. For decades, as an efficient manufacturing technology, additive manufacturing has gradually attracted public attention, and researchers have also used this technology to produce new thermally conductive polymer materials. Here, we review the recent research progress of different 3D printing technologies in heat conduction and the thermal conduction mechanism of polymer matrix composites. Based on the classification of fillers, the research progress of thermally conductive materials prepared by fused filament fabrication (FFF) is discussed. It analyzes the internal relationship between FFF process parameters and the thermal conductivity of polymer matrix composites. Finally, this study summarizes the application and future development direction of thermally conductive composites by FFF.
Processes of Electrospun Polyvinylidene Fluoride-Based Nanofibers, Their Piezoelectric Properties, and Several Fantastic Applications

Since the third scientific and technological revolution, electronic information technology has developed rapidly, and piezoelectric materials that can convert mechanical energy into electrical energy have become a research hotspot. Among them, piezoelectric polymers are widely used in various fields such as water treatment, biomedicine, and flexible sensors due to their good flexibility and weak toxicity. However, compared with ceramic piezoelectric materials, the piezoelectric properties of polymers are poor, so it is very important to improve the piezoelectric properties of polymers. Electrospinning technology can improve the piezoelectric properties of piezoelectric polymers by adjusting electrospinning parameters to control the piezoelectrically active phase transition of polymers. In addition, the prepared nanofibrous membrane is also a good substrate for supporting piezoelectric functional particles, which can also effectively improve the piezoelectric properties of polymers by doping particles. This paper reviews the piezoelectric properties of various electrospun piezoelectric polymer membranes, especially polyvinylidene fluoride (PVDF)-based electrospun nanofibrous membranes (NFs). Additionally, this paper introduces the various methods for increasing piezoelectric properties from the perspective of structure and species. Finally, the applications of NFs in the fields of biology, energy, and photocatalysis are discussed, and the future research directions and development are prospected.

Reciprocity Laws for the Higher Tame Symbol and the Witt Symbol on an Algebraic Surface

Parshin's higher Witt pairing on an arithmetic surface can be combined with the higher tame pairing to form a symbol taking values in the absolute abelian Galois group of the function field. We prove reciprocity laws for this symbol using techniques of Morrow for the Witt symbol and Romo for the higher tame symbol.
Investigation of the Differential Power of Young's Internet Addiction Questionnaire Using the Decision Stump Tree

Background Internet addiction is one of the serious consequences of recent advances in the use of social media. Early detection of Internet addiction is essential because of its harms and is necessary for timely and effective treatment. Aim The aim of this study was to use data mining and an artificial intelligence algorithm to estimate the differential power of each question in the Young Internet Addiction Test and build a decision stump model to predict which item in the questionnaire can be representative of the whole questionnaire. Methods This is a descriptive study conducted at the University of Tabriz, in which 256 undergraduate students were selected in randomized cluster sampling, and they completed Young's IAT (Internet Addiction Test) questionnaire and some demographic questions. The data were statistically analyzed with SPSS and were divided into two groups, normal and addicted, by using a cut-off point. Also, the data of the subjects was used to model the decision stump tree in WEKA. The clustering item was the normal and addicted specifier. Results The study shows that Cronbach's alpha of the IAT is 0.88, which shows good internal integration of subjects that are used to develop the model in WEKA (the Waikato Environment for Knowledge Analysis). Data analysis showed that by using the second question of this questionnaire as the root of the decision stump tree model, it is possible to distinguish between Internet addicts and healthy users with 82% accuracy using this model. Conclusion The study shows innovative ways in which decision stump trees and data mining can help to improve methods used in Clinical Psychotherapy and Human Science. Regarding this, the study showed that early detection of Internet addiction would be possible by using the 2nd question of the IAT. Also, early detection can result in cost-effectiveness for the whole healthcare system.
WHY DO COMPACT ACTIVE GALACTIC NUCLEI AT HIGH REDSHIFT SCINTILLATE LESS?

The fraction of compact active galactic nuclei (AGNs) that exhibit interstellar scintillation (ISS) at radio wavelengths, as well as their scintillation amplitudes, have been found to decrease significantly for sources at redshifts z ≳ 2. This can be attributed to an increase in the angular sizes of the μas-scale cores or a decrease in the flux densities of the compact μas cores relative to that of the mas-scale components with increasing redshift, possibly arising from (1) the space–time curvature of an expanding universe, (2) AGN evolution, (3) source selection biases, (4) scatter broadening in the ionized intergalactic medium (IGM) and intervening galaxies, or (5) gravitational lensing. We examine the frequency scaling of this redshift dependence of ISS to determine its origin, using data from a dual-frequency survey of ISS of 128 sources at 0 ≲ z ≲ 4. We present a novel method of analysis which accounts for selection effects in the source sample. We determine that the redshift dependence of ISS is partially linked to the steepening of source spectral indices (α8.44.9) with redshift, caused either by selection biases or AGN evolution, coupled with weaker ISS in the α8. 44.9 < −0.4 sources. Selecting only the −0.4 < α8. 44.9 < 0.4 sources, we find that the redshift dependence of ISS is still significant, but is not significantly steeper than the expected (1 + z)0.5 scaling of source angular sizes due to cosmological expansion for a brightness temperature and flux-limited sample of sources. We find no significant evidence for scatter broadening in the IGM, ruling it out as the main cause of the redshift dependence of ISS. We obtain an upper limit to IGM scatter broadening of ≲ 110 μas at 4.9 GHz with 99% confidence for all lines of sight and as low as ≲ 8 μas for sight lines to the most compact, ∼10 μas sources.
Effect of Trunk Training on Dynamic Balance in Chronic Stroke Survivor

Stroke leads to muscle paresis, balance and postural control deficits. Balance instability is challenging problem in stroke survivor. Trunk control is prerequisite for balance either static or dynamic. Trunk training encompassed exercises to strengthen trunk muscles on a therapeutic mat (stable surface) and Swiss Ball (unstable surface). The objective was to estimate the effect of trunk training on dynamic balance in chronic stroke patient. The case was of 50 year old female patient with left hemiparesis. She had impaired trunk control and balance and assessed with Trunk Impairment Scale and Berg Balance Scale. The intervention comprised of trunk training of 40-50 minutes 3/week for four week. Trunk impairment scale and Berg balance scale score was improved post intervention which proposed that trunk training is useful to restore dynamic balance. Keywords: Stroke, Trunk Training, Balance
A COMPLETE SAMPLE OF BRIGHT SWIFT LONG GAMMA-RAY BURSTS. I. SAMPLE PRESENTATION, LUMINOSITY FUNCTION AND EVOLUTION

We present a carefully selected sub-sample of Swift long gamma-ray bursts (GRBs) that is complete in redshift. The sample is constructed by considering only bursts with favorable observing conditions for ground-based follow-up searches, which are bright in the 15–150 keV Swift/BAT band, i.e., with 1-s peak photon fluxes in excess to 2.6 photons s−1 cm−2. The sample is composed of 58 bursts, 52 of them with redshift for a completeness level of 90%, while another two have a redshift constraint, reaching a completeness level of 95%. For only three bursts we have no constraint on the redshift. The high level of redshift completeness allows us for the first time to constrain the GRB luminosity function and its evolution with cosmic times in an unbiased way. We find that strong evolution in luminosity (δl = 2.3 ± 0.6) or in density (δd = 1.7 ± 0.5) is required in order to account for the observations. The derived redshift distributions in the two scenarios are consistent with each other, in spite of their different intrinsic redshift distributions. This calls for other indicators to distinguish among different evolution models. Complete samples are at the base of any population studies. In future works we will use this unique sample of Swift bright GRBs to study the properties of the population of long GRBs.
Ultra-processed food consumption and its association with nutritional, functional, and health characteristics in Brazilian elders

Aims: to estimate the dietary energy contribution of ultra-processed foods and the association on nutritional dietary profile, nutritional status, chronic disease, and functional capacity of Brazilian elders. Methods: we performed an epidemiology cross-sectional study conducted with 332 participants (≥60 years old). Food consumption was measured by three 24-h food recall. Foods were classified according to NOVA classification as in natura/minimally processed foods, processed culinary ingredients, processed foods, and ultra-processed foods. Anthropometric variables were used to assess nutritional status, and scales of activities of daily living to assess functional capacity. Chronic diseases were self-reported. Results: the average daily consumption of energy was 2433,96 kcal, being 10.44% from ultra-processed foods. Elders with higher ultra-processed foods intake showed higher consumption of energy, added sugar, total and saturated fat, and fewer consumption of proteins, fibres, potassium, magnesium, iron, zinc, copper, selenium, B6 vitamin e folate. Most participants were independent for functional capacity, overweight, and very high risk for cardiovascular disease, but no statistical significance was observed. No association was found between ultra-processed foods and nutritional dietary profile, nutritional status, chronic disease, and functional capacity. Conclusions: elders who had the highest ultra-processed foods consumption had lower diet quality, although no influences on nutritional status and health variables assessed were observed in this sample.
The Patient’s Voice as a Parent in Mental Health Care: A Qualitative Study

Objective: This study is an evaluation of patients in mental health care who have undertaken treatment with an integrated family approach. The treatment focuses on the mental disorders of patients, their role as parents, the development of their young children, and family relationships. The treatment was conducted by professionals from an adult and a child mental health service in the Netherlands. The aim of the study was to identify the key elements and processes of this approach in order to develop a theoretical model. Background: Parental mental disorders have an impact on parenting and child development. To stop detrimental cascade effects and prevent parents and children from being caught up in the intergenerational transmission of psychopathology, a family approach in mental health care is needed. Methods: A qualitative design was adopted using thematic analysis. Data were collected through 18 interviews with patients. The themes in the interviews were which outcomes the patients experienced and which key elements of the treatment contributed to these outcomes. Results: In general, patients were satisfied with the treatment offered. Improved outcomes were within the domain of the family, the parent-child relationship, individual symptoms, and the functioning of the parent and the child. Patients mentioned six key elements of success in treatment: focus on the whole family, flexible treatment tailored to the situation of the family, components of the whole treatment reinforcing each other, multi-disciplinary consultation among involved professionals, a liaison between adult and child mental health services, and attention to the social and economic environment. Conclusions: According to the majority of patients, treatment with an integrated family approach in mental health care is of value for themselves, their children, and family relationships, especially the parent-child relationship.
Spin alignments within the cosmic web: a theory of constrained tidal torques near filaments

The geometry of the cosmic web drives in part the spin acquisition of galaxies. This can be explained in a Lagrangian framework, by identifying the specific long-wavelength correlations within the primordial Gaussian random field which are relevant to spin acquisition. Tidal Torque Theory is revisited in the context of such anisotropic environments, biased by the presence of a filament within a wall. The point process of filament-type saddles represents it most efficiently. The constrained misalignment between the tidal and the inertia tensors in the vicinity of filament-type saddles simply explains the distribution of spin directions. This misalignment implies in particular an azimuthal orientation for the spins of more massive galaxies and a spin alignment with the filament for less massive galaxies. This prediction is found to be in qualitative agreement with measurements in Gaussian random fields and N-body simulations. It relates the transition mass to the geometry of the saddle, and accordingly predicts its measured scaling with the mass of non-linearity. Implications for galaxy formation and weak lensing are briefly discussed, as is the dual theory of spin alignments in walls.
A Mathematical Relationship between Hydrogenic Periodic Property and Nuclear Properties in Furtherance of Bohr’s Theory

Background: Atomic physics and nuclear matter physics are often exclusively studied. However, atomic properties are a direct function of nuclear properties. Establishing a mathematical relationship between nuclear and atomic properties could serve the interest of nuclear and atomic engineers. Nuclear - and atomic-based instrumentation engineering and nuclear medicine (and perhaps atomic medicine) applications could be the benefits. Objectives: The research is undertaken to 1) link nuclear property, the mass-radius of the nucleon, and ionization energy of hydrogen via the derivation of appropriate equation and 2) determine the mass-radii of the nucleons and some leptons. Methods: Theoretical and computational methods. Results and Discussion: As applicable to the previous results in the literature, the larger the mass of the elementary particles, the longer the radii. For the particles investigated, the order of the radius is muon (m-)<proton (p+)< neutron (n)< tauon (t-) corresponding to increasing mass, m-<p+< n<t-. The values of the mass radii were respectively » 0.1240, 1.1012, 1.1027, and 2.0855 fm. Conclusion: Nuclear properties such as the radius of any nucleon (ΓN) can be mathematically linked to atomic properties such as the ionization energy of hydrogen via equation which shows that ΓN is inversely proportional to the ionization energy of hydrogen and directly proportional to the rest-mass of the particle.
Digital Health Interventions in Depression Care—A Survey on Acceptance from the Perspective of Patients, Their Relatives and Health Professionals

Digital health interventions may contribute to closing the treatment gap for depression by reaching large populations at relatively low costs. This article presents the results of a broad, multisided German survey in 2020 on the acceptance and use of digital health interventions in depression care from the perspective of patients, their relatives, and health professionals. A total of 97 patients and relatives and 229 health professionals participated. Survey participants reported openness towards the use of digital health interventions in depression care but little knowledge and experience in the field. Digital health interventions appear to be a promising opportunity for reducing depressive symptoms and shortening waiting time for depression treatment, especially in rural areas. Providing information and technical competencies may increase awareness and knowledge about digital health interventions and the benefits of depression care.
Strengthening of Biomolecular Engineering Competence for Pharmacists in Batu City through Webinars and Workshops on Isolation of Genetic Material, Real-Time PCR, and its Applications in the Clinical Field

The pandemic of COVID-19 has forced pharmacist assistance practitioners to strive to improve their qualifications and competencies, especially in molecular biology. The human resources competencies in this field are still lacking, resulting in some obstacles in the handling of COVID-19 encountering, thus hampering the acceleration of post-pandemic recovery. The Virus that can spread rapidly requires competent health workers to move as quickly as possible to overcome this pandemic condition. Ignorance of these critical technical matters often occurs so that it affects the identification results, which are expected to be more accurate, precise, and reliable. In a workforce to increase the competency capacity of pharmacist assistants in the biomolecular field, especially in the technical competence of genetic material isolation and PCR methods, the Pharmacy Study Program of Ma Chung University held Webinars and Workshops related to DNA isolation and quality testing. The webinar and workshop on the isolation of genetic material were carried out to implement one of the research topics in the Pharmacy Study Program, especially in the field of development of molecular biology. The essential thing in this webinar and workshop is discussing some critical criteria before the actual virus identification. This program collaborates with PAFI (Indonesian Pharmacy Experts Association) of Batu City as a partner. People who took part in this event consisted of 63 persons from the Batu City and Malang City areas. Most of the participants work in health facilities, with 50% of the participants having isolated genetic material and PCR (Polymerase Chain Reaction). Spreading the pre and post-test with the same questions increased the average acknowledgment score from 42.9 to 61.1. This indicates that continuous training in this field needs to be held on an ongoing program so that the competence of pharmacists in the field of molecular biology is getting better.
Good Roads and Anti-Black Violence

Following Progressive-era advocacy (1890–1930), a modernized road work site emerged in the U.S. South designed to be populated by mobile fleets of Black imprisoned laborers. The forced road work dislodged U.S. roads from their localized production and maintenance so they could assume an expert-led, technological form—physically and discursively. On the road, however, labor was merely a means of violently reifying hierarchical racial differences, making the “good road” a monument to the modern persistence of state-enacted anti-Blackness. This article assesses the emergence of this regional, racial system of anti-Black violence alongside the undertheorized spatial situation of the imprisoned laborers themselves by consulting the report of Bayard Rustin following time spent on a Roxboro, North Carolina, prison road work camp. The report recounts his own experiences along with those of other men, as well as their songs. The laborers’ firsthand accounts foreground persistent desires for loves, families, and homes beyond the racial capitalist traumas undergirding U.S. transportation geographies.
The Selective CO2 Adsorption and Photothermal Conversion Study of an Azo-Based Cobalt-MOF Material

A new metal–organic framework (MOF), [Co2(L)2(azpy)]n (compound 1, H2L = 5-(pyridin-4-ylmethoxy)-isophthalic acid, azpy = 4,4′-azopyridine), was synthesized by a solvothermal method and further characterized by elemental analysis, IR spectra, thermogravimetric analysis, single-crystal and powder X-ray diffraction. The X-ray single-crystal diffraction analysis for compound 1 indicated that two cis L22− ligands connected to two cobalt atoms resulted in a macrocycle structure. Through a series of adsorption tests, we found that compound 1 exhibited a high capacity of CO2, and the adsorption capacity could reach 30.04 cm3/g. More interestingly, under 273 K conditions, the adsorption of CO2 was 41.33 cm3/g. In addition, when the Co-MOF was irradiated by a 730 nm laser, rapid temperature increases for compound 1 were observed (temperature variation in 169 s: 26.6 °C), showing an obvious photothermal conversion performance. The photothermal conversion efficiency reached 20.3%, which might be due to the fact that the parallel arrangement of azo units inhibited non-radiative transition and promoted photothermal conversion. The study provides an efficient strategy for designing MOFs for the adsorption of CO2 and with good photothermal conversion performance.
