Remix

As a term, ‘remix’ has predominantly been associated with music, gesturing towards the act of mixing the elements of an existing musical record to create a renewed version of it. Thus, at its very core, remixing is a material practice; be it the disc-scratching that DJs fall back on to introduce an electric scratching sound to songs, or actually separating elements of a song wherein the melody, the beats, the lyrics that have formed a cohesive union in the original are stripped from the whole, and readied for new combinations and thus new musical objects, remixes are all physical practices. By definition, therefore, a remix is reliant upon an existing sonic media object, leaning not just on its elements but on its memory. While some of the practices associated with the remix have been a part of the sonic landscape of the subcontinent ever since the arrival of sound in the 1930s, the most distinct iteration of the remix emerged in the early 1990s as a subgenre of what was developing then as Indie-pop. As a culturally hybrid product that mixed the musical form of popular Bombay film music, Indian folk music and Western electronic sounds such as electro, rap and reggae, the remix became popular not just within the subcontinent but also with the South Asian diaspora, particularly in Britain, largely due to the popularity of British–Indian DJ Bally Sagoo. Sagoo first gained attention in 1991 with his album Magic Touch that comprised remixes of Pakistani qawwali maestro Nusrat Fateh Ali Khan’s repertoire. His next venture – Bollywood Flashback – was ostensibly the first popular album to remix songs from old Hindi films. He also recorded an album dedicated to remixes of Kishore Kumar’s songs. Following Sagoo, DJs who remixed songs usually retained the original lyrics and the basic melody of the song. The entire emphasis was on recreating a new rhythm, accompanied by instrumentation that insiders within the music industry nebulously described as ‘modern’, or ‘western’, referring not just to them being contemporary media objects, but also signalling their departure from the aesthetic of both film and folk songs of India. The western influence was further highlighted with the addition of rap bridges that consisted of lyrics in English and other non-Indian languages. Most remixes retained the original tune and lyrics, but there were some distinctions: some remixes added beats to the existing vocals by playback singers, while some actually re-recorded the songs with new, and often less-known singers.

Development of piezoresistive PDMS/MWCNT foam nanocomposite sensor with ultrahigh flexibility and compressibility

Polymer foam nanocomposites attract great interest in many wide ranges of biomedical and healthcare monitoring applications. In this study, we investigated the effect of porosity and multi-walled carbon nanotube (MWCNT) content on the piezoresistivity, sensitivity, and mechanical properties of Polydimethylsiloxane (PDMS)/MWCNT foam nanocomposite. The foam nanocomposites were fabricated by particulate leaching method and their electrical and mechanical characteristics were investigated using the different porosity levels (60% and 70%) and different conductive nanofiller contents (0.5 wt.% and 1 wt.%). The foam nanocomposites with 0.5 wt. % MWCNT content and 60% porosity possessed higher pressure sensitivity, higher gage factor, and lower electrical hysteresis along with higher mechanical properties. Moreover, fabricated PDMS/MWCNT foam nanocomposite demonstrated high flexibility, high compressibility, and high recoverability in addition to limited mechanical hysteresis (less than 3%) with a large dynamic sensing range. Contrary to the existing foam nanocomposite samples in the literature, PDMS/MWCNT foam nanocomposites withstood higher pressure ranges (3.5–5 MPa) at limited thickness (average 2.3 mm) without experiencing noticeable macroscopic damage.
Multiple pathways to stabilize/induce an ordered phase in a system exhibiting a reentrant sequence

ABSTRACT Liquid crystals have served as model materials for observing re-entrant phases, now known among a plethora of condensed matter systems spanning from superconductors to proteins. Sadashiva synthesised the organic compounds for the work from Raman Research Institute that laid the claim for having observed a re-entrant nematic in a single component material at atmospheric pressure. With no exception, the presence of such a re-entrant nematic necessitates the existence of an Intermediate smectic phase. After nearly half a century of this ground-breaking research, chemical and thermodynamic routes are well known for the relative stability of the smectic and re-entrant nematic. Here we describe some recent results and new research looking at other pathways to stabilise the smectic phase at the cost of the re-entrant structure. Specifically, we have employed additives such as carbon nanotubes, a non-aromatic polymer and photoisomerisation associated shape change of the molecules to achieve this target. A judicious combination of the nanophase segregation mechanism and the frustrated spin gas model can explain most of these observations. However, the phase diagram obtained in the temperature – intensity of actinic light phase spaces cannot be fully understood by these explanations, for which we have invoked other possible mechanisms.

Integrated Circuit Gold Wire Bonding Measurement Via 3-D Point Cloud Deep Learning

In the semiconductor manufacturing industry, gold wires are commonly used to connect integrated circuits for transmitting signal and power. Hence, gold wire bonding quality inspection is a vital task for the functional stability of the integrated circuit chip. The shape of each gold wire bonding is one of the most important factors influencing the stability of chip performance. However, as the size of gold wire is quite small (around 0.02 mm), it is difficult to quantitatively measure the shape, i.e., the size-related indices. In this article, we propose a novel framework for fully automated gold wire bonding size-related measurement, which is the key step in gold wire bounding quality inspection. First, we employ a 3-D scanning device to obtain the 3-D point cloud of the chip area where gold wire bonding structures are. We then propose a 3-D deep learning-based algorithm to extract multiple gold wire bounding structures from the whole scanned point cloud. With the extracted points, a postprocessing method is introduced to group the gold wire-solder joint pairs. Moreover, we design a point cloud-based calculation model to perform the final size-related measurement. The proposed automated framework achieves high-accuracy quantitative measurement of gold wire bonding structures on the scale of 0.02 mm for the first time. The effectiveness of the proposed measurement framework is demonstrated by the experiments.
Minimization of wiring inductance in high power IGBT inverter

The wiring inductance is one of main causes limiting the use of the inverter in hard commutation mode, particularly when voltage, current and switching frequency are increased. The busbar technology is the means that allows one to reach low wiring inductance between DC source and power switches in spite of relatively long connections. This paper deals with studies of busbar structure applied to the high power inverters in order to improve their performances. Two structures of wiring are tested; the traditional one and busbar technology. Experimental and simulation results show that this last technique permits to obtain very low wiring inductance so that no snubber circuits are needed.
Examining the Cold War in the 1980s with Comic Books

Abstract The role of literacy in social studies education has been greatly elevated over the last decade. The National Council for the Social Studies (NCSS) models through the indicators of its C3 Framework how to strengthen K-12 students’ disciplinary thinking, literacy, and argumentation skills in the four core social studies disciplines: civics, history, geography, and economics. One resource that social studies teachers can use to address the indicators within the C3 Framework is comic books. Comic books employ both visual and textual modalities to convey meaning, through text boxes, people’s facial expressions, and imagery to capture the author’s arguments. The various modes of communication utilized in comic books allow students to construct meaning. In this article, we discuss how to use two comic books, Batman: Ten Nights of the Beast, and Suicide Squad: Trial by Fire, to teach about the Cold War in the 1980s. We start by giving a brief historical overview of the Cold War in the 1980s. Then, the focus of the article shifts to provide an examination of the potential benefits of utilizing comic books. This section also discusses how popular culture reflects the issues, values, and beliefs of an historical era. Two activities are given that scaffold how high school social studies teachers can employ these comic books to analyze important components of the Cold War in the 1980s. The steps and resources needed to implement our activities are provided.
Hyperelastic Material Parameter Determination and Numerical Study of TPU and PDMS Dampers

Dampers provide safety by controlling unwanted motion that is caused due to the conversion of mechanical work into another form of energy (e.g., heat). State-of-the-art materials are elastomers and include thermoplastic elastomers. For the polymer-appropriate replacement of multi-component shock absorbers comprising mounts, rods, hydraulic fluids, pneumatic devices, or electro-magnetic devices, among others, in-depth insights into the mechanical characteristics of damper materials are required. The ultimate objective is to reduce complexity by utilizing inherent material damping rather than structural (multi-component) damping properties. The objective of this work was to compare the damping behavior of different elastomeric materials including thermoplastic poly(urethane) (TPU) and silicone rubber blends (mixtures of different poly(dimethylsiloxane) (PDMS)). Therefore, the materials were hyper- and viscoelastic characterized, a finite element calculation of a ball drop test was performed, and for validation, the rebound resilience was measured experimentally. The results revealed that the material parameter determination methodology is reliable, and the data that were applied for simulation led to realistic predictions. Interestingly, the rebound resilience of the mixture of soft and hard PDMS (50:50) wt% was the highest, and the lowest values were measured for TPU.
Adverse Pregnancy Outcomes and Maternal Chronic Diseases in the Future: A Cross-Sectional Study Using KoGES-HEXA Data

Adverse pregnancy outcomes (APOs) are associated with an increased risk of chronic diseases, including cardiovascular disease (CVD) and metabolic syndrome (MS), in the future. We designed a large-scale cohort study to evaluate the influence of APOs (preeclampsia, gestational diabetes mellitus (GDM), stillbirth, macrosomia, and low birth weight) on the incidence of chronic diseases, body measurements, and serum biochemistry in the future and investigate whether combinations of APOs had additive effects on chronic diseases. We used health examinee data from the Korean Genome and Epidemiology Study (KoGES-HEXA) and extracted data of parous women (n = 30,174; mean age, 53.02 years) for the analysis. Women with APOs were more frequently diagnosed with chronic diseases and had a family history of chronic diseases compared with women without APOs. Composite APOs were associated with an increased risk of hypertension, diabetes mellitus, hyperlipidemia, angina pectoris, stroke, and MS (adjusted odds ratio: 1.093, 1.379, 1.269, 1.351, 1.414, and 1.104, respectively) after adjustment for family history and social behaviors. Preeclampsia and GDM were associated with an increased risk of some chronic diseases; however, the combination of preeclampsia and GDM did not have an additive effect on the risk. APOs moderately influenced the future development of maternal CVD and metabolic derangements, independent of family history and social behaviors.
Dual-polarized planar antenna fed by dog-bone slots

A dual-polarized planar antenna composed of a microstrip antennadual-band antenna is used as an efficient radiator in the fields of satellite communication and remote sensing. One problem with such an antenna, however, is the low isolation characteristics of its radiator. In order to try to resolve this problem, a new type of dual-polarized planar antenna fed by dog-bone slots was developed and tested. The basic design technique and radiation properties of this new antenna are presented. Various experiments were carried out in the C-band to examine the performance of the antenna. Excellent return-loss and isolation characteristics were achieved using the antenna. Furthermore,the simulated results obtained using an IE3D simulator agreed well with the experimental results. Therefore, this type of planar antenna is considered to be an effective model for a dual-polarized planar antenna.
Domain Decomposition FDTD Algorithm Combining with Numerical TL Calibration Technique for Parameter Extraction of Substrate Integrated Circuits

The substrate integrated waveguide (SIW) is useful for the design of millimeter-wave planar circuits such as filters, resonators and antennas. In this paper, an efficient hybrid algorithm called the domain decomposition finite difference time domain (DD-FDTD) method combining with a new numerical through-line (TL) calibration technique, is proposed and developed for the accurate parameter extraction of substrate integrated circuits (SICs). By means of this calibration technique, the FDTD method can be used to extract the circuit parameters of planar SIC discontinuities. The use of the domain decomposition can largely simplify the procedure of programming and simulation, increase the reliability of simulation, and make the adoption of distributed computing more convenient. The introduction of the TL calibration technique not only makes it possible to use the FDTD method to extract the parameters of SICs, but also accurately obtain the unknown complex propagation constant of the SIW simultaneously. Simulation and measurement results have verified this hybrid algorithm.
Sampling reconstruction of N-dimensional band-limited images after multilinear filtering

The generalized sampling expansion of A. Papoulis (1977) for a multichannel configuration is investigated for the case where the bandlimited input depends on N real-variables t/sub 1/,. ,t/sub V/ and is used as a common input to a parallel bank of m independent N-dimensional linear shift-invariant filters. The input is assumed to have its N-dimensional Fourier transform bandlimited to the frequency range mod omega /sub i/ mod >
Coupling traction force patterns and actomyosin wave dynamics reveals mechanics of cell motion

Motile cells can use and switch between different modes of migration. Here, we use traction force microscopy and fluorescent labeling of actin and myosin to quantify and correlate traction force patterns and cytoskeletal distributions in Dictyostelium discoideum cells that move and switch between keratocyte‐like fan‐shaped, oscillatory, and amoeboid modes. We find that the wave dynamics of the cytoskeletal components critically determine the traction force pattern, cell morphology, and migration mode. Furthermore, we find that fan‐shaped cells can exhibit two different propulsion mechanisms, each with a distinct traction force pattern. Finally, the traction force patterns can be recapitulated using a computational model, which uses the experimentally determined spatiotemporal distributions of actin and myosin forces and a viscous cytoskeletal network. Our results suggest that cell motion can be generated by friction between the flow of this network and the substrate.
How Family Relationships Predict the Effectiveness of a Psychosocial Group Intervention among War-Affected Children

Family relationships habitually shape the way traumatic events affect children's mental health in a context of war and violence, but research is scarce on the role these relationships play in the success of psychosocial interventions. This study is a secondary analysis of previously identified family system types that are based on attachment, parenting, and siblingship, and of the influence they have on the effectiveness of teaching recovery techniques (TRT). TRT is a psychosocial group intervention aimed at reducing children's mental health problems and increasing their psychosocial resources. We tested three hypotheses. First was the compensation hypothesis, which holds that children from families with negative relationships benefit a great deal from the TRT intervention. The second was the accumulative hypothesis, which maintains that children from families with negative relationships do not benefit from the intervention. The third, the buffering hypothesis, states that children from families with positive relationships benefit a great deal from the intervention. The family sample consists of 325 Palestinian mothers and fathers and one of their children (age 10–13). Children participated either in the TRT intervention or waiting-list control groups. Their self-reported post-traumatic stress symptoms, emotional and conduct problems, positive resources, and prosocial behavior were assessed at baseline, three months post-intervention, and at a six-month follow-up. We found that family type was significantly associated with TRT effectiveness, which supports the compensation and buffering hypotheses. Children with insecure and negative family relationships and those from families with discrepant perceptions of relationship quality showed a decline in emotional problems across the three assessments, and an increase in positive resources. Children from families with highly secure, positive relationships and those with moderately secure, neutral relationships showed increased positive resources and prosocial behavior in the control group as well. We argue that a family system approach can deepen understanding of the mechanisms of successful psychosocial interventions and, therefore, that family relations should be taken into account when tailoring such interventions for traumatized children.
Effectiveness of Water, Sanitation and Hygiene (WASH) Intervention for School going Children on Hygiene Practices, Absenteeism, Diarrhea, and Respiratory Infection: An Interventional Study Protocol

Introduction: Safe drinking water, sanitation and hygiene beyond the household, and particularly in the school setting, are crucial to the health and education of children. Ashram schools where children from tribal community are taking education in India are mostly ignored. Thus, inclusion of water, sanitation and hygiene (WASH) in schools as part of the SDG, necessitates assessing the coverage and utilization in all types of schools; Government, private, funded including Ashram (residential) schools. Hence, we plan this research to study the effectiveness of proposed WASH in Ashram school with regards to hygiene practices, diarrheal diseases, respiratory infection and school absenteeism. Methods: Interventional study will be conducted in all eight Ashram schools of Wardha district. Baseline data regarding WASH practices and absenteeism, diarrhea, and respiratory infection will be collected. Intervention model for adopting safe WASH practices will be developed implemented in randomly selected four ashram schools. Survey and interview questionnaire will be adopted from UNICEF monitoring package modules. Children of forth, fifth and sixth classes (460), teachers, and Principles(8) will be interviewed; and school environment will be reviewed. After collection of post intervention data in ODK tool, descriptive statistics, two-sample t-tests and unadjusted mean percentages for all outcome variables were calculated by aggregating individual-level data to the school level. Conclusion: The intervention package is based on community mobilization and participation; life skill education, capacity building of school staff related to WASH. This will contribute to bring long term changes and improvement in health status and academic performance of school children.

Evaluation of calcium-fortified municipal water as a public health intervention to mitigate lead burdens

Lead has adverse effects on health, society, and the economy. Lead exposure results in increased blood lead levels and storage in bones. Calcium and lead are competitively absorbed and as such calcium can be used to mitigate the body lead burden. Twenty-eight quantitative research studies were reviewed that examined lead exposure (in blood, bone, or breastmilk) and calcium intake or serum calcium to evaluate the efficacy and safety of fortifying potable water supplies with calcium to mitigate lead absorption or resorption. Eighteen of the studies reported a significant inverse relationship between biomarker lead levels and calcium intake or serum calcium. The relationship was most evident with high calcium intake, suggesting a dose-dependent relationship. An intervention with calcium-fortified water could offer an accessible source of supplemental calcium to help meet the recommended dietary allowance (RDA) and mitigate lead absorption. A concentration of 60 mg-Ca/L can supply 22.0 and 16.3% of a 1,000 mg-Ca RDA for men and women, respectively, at the recommended daily water intake.
Reframing organizations in the digital age: A qualitative study exploring institutional social media adoption involving emergency physicians and other researchers

Background: Social media is changing the modern academic landscape; this study sought to explore how organizational structures support or inhibit the harnessing of social media use in academic contexts and knowledge translation. Methods: A qualitative study was conducted using framework analysis based on the Bolman and Deal’s Four-Frame Model—structural, human resources, political and symbolic. The research team used the snowball sampling technique to recruit participants following the completion of each participant’s semi-structured interview. A member check was completed to ensure rigour. Results: 16 social media educators and experts from several countries participated in the study. Study findings showed that within the Structural Frame, participants’ organizations were reported to have with diverse hierarchical structures, ranging hospital-based (strict), education institutional-based and online only groups (malleable). The Human Resources Frame revealed that most participants’ social media organizations operated on unpaid volunteer staff. The training of these staff was primarily via role-modeling and mentorship. Regarding the Political Frame, social media helped participants accumulate scholarly currency and influence within their field of practice. The Symbolic Frame showed a wide range of traditional to non-traditional organizational supports, which interacted with both intrinsic to extrinsic motivation. Conclusions: Bolman and Deal’s Four-Frame Model framework may serve as an effective guideline for academic leaders who wish to strategically implement or enhance social media use into their organizations. The key insights that we have gained from our participants are how new emerging forms of scholarly pursuits can be more effectively enabled or hindered by the attributes of the organization within which these are occurring.
