Published: May 2016

Weight control system on the feeder conveyor determines the factor of the quality of products within an industry. The dynamics of the flow rate of material through the feeder conveyor weigh requires a good level of performance controllers. The base of current controllers such as FLC (Fuzzy Logic Controller) requires a certain amount of knowledge and expertise in its design that will make it difficult to achieve good system performance. These difficulties can be overcome by using systems based on ANFIS (Adaptive Neuro-Fuzzy Inference System). By doing the learning offline, using ANFIS can be obtained by fuzzy inference systems to create a controller FLC. Microcontroller have FLC controller program, its integrated with notebook can monitor and control the notebook weigh feeder conveyor system. Designing a system that has been created will give good results with an average error value of 3.86% at the set-point of 1000 grams / minute, and the average error of 5.03% on set-point 2000 grams / minute in ten times testing.

Grupos populares brasileiros: uma compreensão acerca de suas diversas formas de participação política a partir da obra “etnografias da participação”
Authors: Magalhães Alânia 
Published: May 2016

O presente trabalho tem como objetivo discorrer sobre a coletânea Etnografias da Participação analisando os artigos presentes na obra, organizada por Claudia Fonseca e Jurema Brites. Para enriquecer o estudo acerca dessa obra, fez-se necessário o acréscimo de conceitos estabelecidos por outros autores, tais como Dumont e Duarte et al., que, de forma inusitada, clarificam as noções de desigualdade presentes em Etnografias da Participação. De um modo geral, conclui-se que os artigos reunidos na obra em análise não pretendem defender a conversão dos grupos populares a um modelo preestabelecido de cidadania. Esses artigos acabam por evidenciar que o problema encontra-se em um sistema injusto e desigual, e não nas expressões políticas dos pobres.

Straipsnio tikslas – remiantis jaunimo požiūriu, išanalizuoti kalendorinių švenčių šventimo skirtumus tarp kartų, nustatyti mėgstamiausias jaunimo šventes ir su jų šventimu susijusius kontekstus. Etnografinių duomenų analizė rodo, kad visos trys respondentų šeimos kartos (seneliai, tėvai ir vaikaičiai) dažniausia švenčia šias šventes: Kūčias / šv. Kalėdas, šv. Velykas, Naujuosius metus, Visų šventųjų / Vėlinių dienas, Jonines. Jaunimas linkęs pabrėžti savo švenčiamų švenčių tęstinumą. Teigiama, kad šventes jie perėmė iš senelių, tėvų ir dažnai švenčia su jais drauge. XXI a. pradžios studentiško jaunimo pačios mėgstamiausios šventės yra Kūčios, šv. Kalėdos. Paminėtos ir kitos šventės (šv. Velykos, Joninės, Visų šventųjų / Vėlinių dienos, Naujieji metai ir Užgavėnės), tačiau joms dėmesio skiriama kur kas mažiau. Pagrindiniai motyvai, kodėl Kūčios ir šv. Kalėdos yra mėgstamiausios respondentų šventės, yra susiję su socialiniais santykiais, žmonių prisiminimais apie šventes, ypač likusiais iš vaikystės, pasiruošimu šventėms ir jų šventimo specifika.

Abstract
The exceptionally high thermal conductivity of polycrystalline diamond (>2000 W m−1 K−1) makes it a very attractive material for optimizing the thermal management of high-power devices. In this paper, the thermal conductivity of a diamond sample capturing grain size evolution from nucleation towards the growth surface is studied using an optimized 3ω technique. The thermal conductivity is found to decrease with decreasing grain size, which is in good agreement with theory. These results clearly reveal the minimum film thickness and polishing thickness from nucleation needed to achieve single-crystal diamond performance, and thus enable production of an optimal polycrystalline diamond for heat-spreading applications.

Published: September 2024

AbstractPurposeTo characterize the dose‐response, energy dependence, postexposure changes, orientation dependence, and spatial capabilities of LD‐V1, a new low‐dose Gafchromic film for low‐energy x‐ray dosimetry.MethodsA single sheet of LD‐V1 Gafchromic film was cut into 15 × 20 mm2 rectangles with a notch to track orientation. Eight different doses between 5 and 320 mGy were delivered by an MXR‐160/22 x‐ray tube using x‐ray beams of 90, 100, and 120 kVp filtered with 3 mm of Al and 2 mm of Ti. The 120 kVp films were scanned at 1, 1.5, 2, 3, 12, 24, 48, 72, and 168 h postexposure in portrait orientation and additionally scanned in landscape orientation at 24 h. The 90 and 100 kVp films were scanned at 24 h postexposure in portrait orientation. Lastly, a 20 × 200 mm2 strip of film was irradiated using a thin‐slit imaging collimator and scanned 24 h postexposure to test the film performance in an x‐ray imaging application.ResultsOf the three color channels, the red channel was found to produce a dose‐response curve with a large range of net optical density (netOD) values across the considered dose range. A prominent energy dependence was discovered, resulting in dose discrepancies on the scale of 17 mGy between 90 and 120 kVp for a dose of 80 mGy. The measured postexposure changes suggest that the calibration irradiation‐to‐scan time should be longer than 12 h with a ± 4 h scanning time window for dose errors of <0.5%. An average dose difference of 3.4% was found between the two scanning orientations. Lastly, noise of 4% was measured in the thin slit collimator film for a dose of 30 mGy.ConclusionsWe have characterized the LD‐V1 film for low‐energy, low‐dose x‐ray dosimetry. Energy, scan‐time, and orientation dependencies should be considered when using this film.
Flexoelectric Effect in Thin Films: Theory and Applications
Authors: Jia Xiaotong , Guo Rui , Chen Jingsheng , Yan Xiaobing 
Published: September 2024

AbstractThe flexoelectric effect describes phenomena where strain gradients induce electrical polarization and electric field gradients cause strain in materials. This specific type of electromechanical coupling effect is remarkable for being independent of material symmetry, Curie temperature, and it exhibits notable effects in small‐sized materials. The study of flexoelectric effects has provided fresh insights into materials science, particularly highlighting how thin‐film structures, with their unique geometrical and dimensional attributes, are highly responsive to flexoelectric influences, thereby offering significant opportunities for modulating electrical properties. Herein, this paper presents the fundamental concepts and theories underlying the flexoelectric effect are presented. Various methods for inducing this effect in thin films are explored, including the optimization of growth and deposition conditions, and the application of external mechanical stresses to create strain gradients. Additionally, recent advances in utilizing the flexoelectric effect to modulate ferroelectric domains, modify properties of thin films, and enhance functionalities in photovoltaic systems, nanogenerators, sensors, and actuators are reviewed. Finally, the challenges and future prospects for flexoelectric effects in advanced electronics are briefly presented.

AbstractThermoset toughness and deconstructability are often opposing features; simultaneously improving both without sacrificing other mechanical properties (e.g., stiffness and tensile strength) is difficult, but, if achieved, could enhance the usage lifetime and end‐of‐life options for these materials. Here, a strategy that addresses this challenge in the context of photopolymer resins commonly used for 3D printing of glassy, acrylic thermosets is introduced. It is shown that incorporating bis‐acrylate “transferinkers,” which are cross‐linkers capable of undergoing degenerative chain transfer and new strand growth, as additives (5–25 mol%) into homemade or commercially available photopolymer resins leads to photopolymer thermosets with substantially improved tensile toughness and triggered chemical deconstructability with minimal impacts on Young's moduli, tensile strengths, and glass transition temperatures. These properties result from a transferinker‐driven topological transition in network structure from the densely cross‐linked long, heterogeneous primary strands of traditional photopolymer networks to more uniform, star‐like networks with few dangling ends; the latter structure more effectively bear stress yet is also more easily depercolated via solvolysis. Thus, transferinkers represent a simple and effective strategy for improving the mechanical properties of photopolymer thermosets and providing a mechanism for their triggered deconstructability.

AbstractScalable fiber lithium‐ion batteries (FLIBs) have garnered significant attention due to huge potential applications in wearable technology. However, their widespread applications have been limited by inadequate cycle and calendar life, primarily due to the high permeability of the encapsulation layer to water vapor in ambient air. To address this challenge, an ultra‐high barrier composite tube is developed by blending polytrifluorochloroethylene (PCTFE) with organically modified montmorillonite (OMMT) for the continuous packaging of FLIBs. Due to the high crystallinity (≈40.21%) and small free volume (103.443 Å3), the PCTFE tube exhibited a low water vapor transmission rate (WVTR) of 0.123 mg day−1 pkg−1. Furthermore, through the melt extrusion, OMMT with its plate‐like morphology are fully exfoliated and dispersed within the PCTFE matrix. This created more complex pathways for water, increasing the diffusion path length and thereby reducing WVTR to 0.006 mg day−1 pkg−1. This innovation enabled an ultra‐long calendar life of 200 days and cycle life of 870 cycles for FLIBs, with over 80% capacity retention in ambient air. Additionally, 2%OMMT‐PCTFE‐FLIBs exhibited excellent flexibility, retaining an impressive 85.31% capacity after 10 000 bending cycles. This research presents a simple yet effective approach to enhance the lifetime and practicality of FLIBs through building a high‐performance polymer‐based encapsulation layer.

AbstractColorectal cancer (CRC) is one of the most prevalent forms of cancer. CircRNAs have emerged as promising biomarkers for cancer diagnosis and prognosis evaluation. However, novel circRNAs as potential biomarkers for CRC still need further exploration and validation, and precise detection methods are yet to be developed. Herein, we report for the first time the use of droplets Cas13a to detect the circWDR37 as a biomarker of CRC. The arraystar circRNA microarray assays, functional experiments in vitro and in vivo, and qPCR were performed to discover and validate that circWDR37 is a biomarker for early screening and prognosis evaluation of CRC. A new technology named µDCR, which accurately detects circWDR37, has been developed by combining microfluidic droplets with CRISPR/Cas13a and recombinase polymerase amplification (RPA). Meanwhile, the role of crowding agent in improving the performance of Cas13a was uncovered. The 4% polyethylene glycol 8000 and 3% dextran‐10 significantly improved the response speed and sensitivity of one‐pot Cas13a‐RPA reaction. The detection limit of circWDR37 by µDCR was found to be 10 copies/mL, which is higher than that of qPCR. The clinical sample findings demonstrated that circWDR37 detection can be utilized to effectively screen for CRC at an early stage and enable accurate assessment of prognosis. CircWDR37 is confirmed as a groundbreaking biomarker for both diagnosis and prognosis evaluation in CRC patients. Furthermore, our innovative µDCR method for detecting circWDR37 demonstrates impressive attributes such as streamlined operation, rapidity, and high‐throughput, making it an optimal technology platform for the noninvasive screening of CRC.

Published: September 2024

AbstractImmunoglobulin light chain (AL) amyloidosis is a multisystem disease with varied treatment options and disease‐related outcomes. Current staging systems rely on a limited number of cardiac, renal, and plasma cell dyscrasia biomarkers. To improve prognostication for all‐cause mortality and end‐stage kidney disease (ESKD), we applied unsupervised machine learning using a comprehensive set of clinical and laboratory parameters. Our study cohort comprised 2067 patients with newly diagnosed, biopsy‐proven AL amyloidosis from the Boston University Amyloidosis Center. Variables included 31 clinical symptoms and 28 baseline laboratory values. Our clustering algorithm identified three subgroups of AL amyloidosis (low‐risk, intermediate‐risk, and high‐risk) with distinct clinical phenotypes and median overall survival (OS) estimates of 6.1, 3.7, and 1.2 years, respectively. The 10‐year adjusted cumulative incidences of all‐cause mortality were 66.8% (95% CI 63.4–70.1), 75.4% (95% CI 72.1–78.6), and 90.6% (95% CI 87.4–93.3) for low, intermediate, and high‐risk subgroups. The 10‐year adjusted cumulative incidences of end‐stage kidney disease (ESKD) were 20.4% (95% CI 6.1–24.5), 37.6% (95% CI 31.8–43.8), and 6.7% (95% CI 2.8–11.3) for low‐risk, intermediate‐risk, and high‐risk subgroups. Finally, we trained a classifier for external validation with high cross‐validation accuracy (85% [95% CI 83–86]) using a subset of easily obtainable clinical parameters. This marks an initial stride toward integrating precision medicine into risk stratification of AL amyloidosis for both all‐cause mortality and ESKD.
