Modern, organic shaped, building façades are often created by joining together hundreds of flat panels, resulting in high production complexity. To reduce cost it is important to design the façade using the fewest possible unique panels. Each unique panel increases design and production times so using many repeated panels enables batch production, lowering cost. To optimise the panel layout with the fewest unique panels a ‘point equilibrium’ algorithm has been developed to position the corners of the panels (nodes) on a parametric surface. In the developed theory a set of hypothetical, electrically charged particles is randomly placed upon the façade surface and allowed to repel each other. They eventually settle into an equilibrium position, with similar distances between adjacent nodes and hence produce a large number of similar triangles. An example of a façade demonstrating the practicability of this technique for constructing panel layouts is given.

Composite panels are designed to be fabricated by adding Styrofoam, glass wool, and urethane into steel plates before integration with adhesive materials. As these panels exhibit good workability, cost efficiency, and heat insulation performance, they are widely used as building materials for plant or storage facilities. However, fire safety still needs to be addressed, because these panels can potentially cause large fires. As firewater cannot easily penetrate the material inside the panel, extinguishing any fires caused is difficult. Furthermore, the imperfect combustion of the core material tends to generate a large volume of toxic gas, resulting in serious damage to human life. In addition, the high risk of collapse makes fire-fighting activities more difficult. Flame spread prevention systems optimized for composite panels have been developed for more effective fire suppression based on accumulative research outcomes obtained thus far. Related test methods were reviewed before successfully demonstrating the performance of the developed systems. The existing composite panel structure—wherein the developed system was not applied-burned out after 5 min; however, when the developed system was applied to the composite panels, the structure was covered in soot after 15 min. The structure was designed by applying the developed system to a virtual factory building, and the construction standard was reviewed.

The structural safety of solar cells mounted on deployable solar panels in the launch vibration environment is a significant aspect of a successful CubeSat mission. This paper presents a novel highly damped deployable solar panel module that is effective in ensuring structural protection of solar cells under the launch environment by rapidly suppressing the vibrations transmitting through the solar panel by constrained layer damping achieved using printed circuit board (PCB)-based multilayered thin stiffeners with double-sided viscoelastic tapes. A high-damping solar panel demonstration model with a three-pogo pin-based burn wire release mechanism was fabricated and tested for application in the 6U CubeSat “STEP Cube Lab-II” developed by Chosun University, South Korea. The reliable release function and radiation hardness assurance of the mechanism in an in-orbit environment were confirmed by performing solar panel deployment tests and radiation tests, respectively. The design effectiveness and structural safety of the proposed solar panel module were validated by launch vibration and in-orbit environment tests at the qualification level.

ObjectiveTo test the utility and diagnostic yield of a medical-exome gene panel for identifying pathogenic variants in Mendelian disorders.MethodsNext-generation sequencing was performed with the TruSight One gene panel (targeting 4813 genes) followed by MiSeq sequencing on 216 patients who presented with suspected genetic disorders as assessed by their attending physicians.ResultsThere were 56 pathogenic and 36 likely pathogenic variants across 57 genes identified in 87 patients. Causal mutations were more likely to be truncating and from patients with a prior clinical diagnosis. Another 18 promising variants need further evaluation for more evidence to meet the requirement for potential upgrade to pathogenic. Forty-five of the 92 clinically significant variants were novel.ConclusionThe 40.3% positive yield compares favourably with similar studies using either this panel or whole exome sequencing, demonstrating that large gene panels could be a good alternative to whole exome sequencing for quick genetic confirmation of Mendelian disorders.

Abstract Sandwich panels made of fibre-reinforced plastic (FRP) skins and a honeycomb core can be effectively damped through the choice of the skin and especially of the core materials. Because the core is often highly damped, a lateral deflection that causes more shearing of the core than bending of the skin increases sandwich damping. Aside from the skin and the core material properties, the shearing/bending ratio depends on a number of other, often interacting, factors, including the sandwich planar as well as transverse dimensions, the particular modal pattern in which the panel vibrates and its relationship to the type of skin layup, as well as the panel end conditions. In the present work, using a simple, first-order shear deformation theory, damping results have been produced for simple modes of vibration of a sandwich panel comprising composite skins and a damped honeycomb core, demonstrating the mechanisms by which the above factors affect the FRP skin/honeycomb core sandwich damping.

In this paper, the element-free kernel particle Ritz method or in short the kp-Ritz method, is developed and implemented for the free vibration analysis of rotating cylindrical panels. Over the years, researchers have employed various trial or admissible functions, such as harmonic and hyperbolic functions as well as polynomials, in the Ritz approximate approach for structural vibration analyses. The present work represents a significant development whereby 2-D reproducing kernel functions are employed to approximate the displacement field. The resulting kp-Ritz method represents the methodology development aspect of this paper. Further the rotating panel problem selected for demonstrating the accuracy and efficiency of this new methodology is also an important contribution of this paper. Although there is a moderate amount of published information on the vibration of rotating cylindrical shells, corresponding studies on rotating panels are conspicuously lacking. This is the first instance in which results have been obtained for rotating cylindrical panels whereby the essential boundary conditions have been fully enforced.

A quantitative assessment of the material flux emerging from a pilot plant for the treatment of end-of-life photovoltaic panel waste was reported. The process included the manual dismantling of aluminum frames, mechanical treatment for size reduction, and the physical treatment of the milled materials for the release of coarse glass from the encapsulant polymer. Demonstration activities were performed using 1 ton of Si-, 1 ton of CdTe-, and 1 ton of CIGS-based photovoltaic panels (investigated separately), confirming the ability of the process to treat different photovoltaic technologies. The characterization of the input materials was performed and compared with previous literature data. The major bottleneck in the definition of an effective process option for the treatment of different panel technologies was emphasized by the high heterogeneity reported. Mass balances for the proposed process were derived by the recovered material flow. It was highlighted that in processes based on mechanical treatments, producing predominantly coarse fractions allows for the facile separation of most of the valuable components. In this perspective, the present work offers further insights into the design of recycling process to reach increased profitability/sustainability, especially considering the distributions of valuable metals in the process products.

A finite element model is developed in this paper to simulate the perforation of aluminium foam sandwich panels subjected to high velocity impact using the commercial finite element analysis software LS-DYNA. The aluminum foam core is governed by the material model of crushable foam materials, while both aluminium alloy face sheets are modeled with the simplified Johnson-Cook material model. A non-linear cohesive contact model is employed to simulate failure between adjacent layers, and an erosion contact model is used to define contact between bullets and panels. All components in the model are meshed with 3D solid element SOLID 164. The developed finite element model is used to simulate the dynamic response of an aluminium foam sandwich panel subjected to projectile impact at velocity ranging from 76 m/s to 187m/s. The relationship between initial velocity and exit velocity of the projectile obtained from numerical modelling agrees well with that obtained from experimental study, demonstrating the effectiveness of the developed finite element model in simulating perforation of sandwich panels subjected to high velocity impact.

The present paper is aimed at demonstrating the capabilities of digital image analysis (DIA) to support conservation of painted artwork. Laser-induced fluorescence (LIF) imaging has been usually used in the diagnosis of wall paintings. In this case, LIF is applied to the case study of a painted wooden canopy, and most successful data processing techniques are presented in the discussion of results. The Jesús del Gran Poder canopy, completed by Francisco Ruiz Gijón in 1692, is an oil panel painting on wood. Eight panels of the canopy have been study by LIF. This technique is capable of remotely acquiring hyperspectral images operating in fluorescence mode following ultraviolet laser excitation. LIF spectra combined with principal component analysis, spectral angle mapper, and DIA provide a chemical mapping of the treated wooden surface of the panels. Besides, LIF spectrum is as a fingerprint of the panels that allows stablishing differences between them. LIF imaging analysis has proven to be a very useful tool for mapping retouching work, tracking previous restorations, and detecting chemicals on the wood in order to monitor restorations.

Brunelleschi's lost panel painting of the Florence Baptistery, created in the early 15th century, is frequently cited as the first work to accurately use perspective. The system he used is unknown, and the only information about the painting mentions a demonstration by which the painting was viewed through a hole in the panel as a reflected image in a mirror. The author argues here that the image was created in a camera obscura using the panel and a mirror in the same relationship as used in the demonstration. The author also proposes that the process revealed perspective's basic “rule”: Vanishing points for parallel, horizontal lines exist at the eye level.

ArianeGroup and Aurock led a feasibility study through the realization of a scale 1 TA6V demonstrator, using superplastic forming (SPF). ArianeGroup designed the demonstrator according to its knowledge of representative structures, comprising singularities: welds, stiffeners and areas with important thicknesses variations. Aurock performed first numerical simulations of the complete process, putting in evidence the various difficulties to be solved. Then, the demonstrator was physically carried out. Once the demonstration was virtually obtained, each steps of the process were experimented: welding of thick plates with limited deformation, machining of flat panels, pre-forming by rolling and final SPF. For the SPF step, a heating cover and a reinforced refractory castable die were manufactured. Infrared emitters’ position and heating power regulation laws were carefully defined, for the panel to be kept at the correct temperature until being formed. The SPF step led to a successful demonstration of the representative structure. The experimental approach confirmed the process modelling predictability. Limited Scale 1 demonstration was necessary to ensure the process validity with real thicknesses and thickness variations, which are known to mask problems if scale reductions are used without precautions. This methodology can be transfer to a real structure only by tooling adaptations, without additional feasibility works.

Change in gene expression is inevitable in cancer development. With more studies demonstrating the contributions of cancer stem cells (CSCs) in colorectal cancer (CRC) development, this study is aimed at investigating whether rectal swab specimen serves as a tool for detection of dysregulation of CSC or stem cell (SC) markers and at evaluating its potential as a new promising screening method for high-risk patients. Expression levels of 15 pluripotency-associated genes were assessed by quantitative PCR in 53 rectal swab specimens referred for endoscopic screening. Dysregulated genes and joint panels based on such genes were examined for their diagnostic potentials for both polyp and CRC. Out of 15 genes, Oct4, CD26, c-MYC, and CXCR4 showed significantly differential expression among normal, polyp, and CRC patients. A panel of Oct4 and CD26 showed an AUC value of 0.80 ( p = 0.003 ) in identifying CRC patients from polyp/normal subjects, with sensitivity and specificity of 84.6% and 69.2%. A panel of c-MYC and CXCR4 achieved CRC/polyp identification with an AUC value of 0.79 ( p = 0.002 ), with a sensitivity of 82.8% and specificity of 80.0%. The sensitivity for polyp and CRC was 80.0% and 85.7%, respectively. Further analysis showed that higher c-MYC and CXCR4 level was detected in normal subjects who developed polyps after 5-6 years, in comparison with subjects with no lesion developed, and the AUC of the c-MYC and CXCR4 panel increased to 0.88 ( p < 0.001 ), with sensitivity and specificity of 84.4% and 92.3%, respectively, when these patients were included in the polyp group. This study suggests that the Oct4 and CD26 panel is a promising biomarker for distinguishing CRC from normal and polyp patients, whereas the c-MYC and CXCR4 panel may identify polyp and CRC from normal individuals.

This document explains and demonstrates an experimental method to determine principal plastic strains in industrially stamped sheet panels. The principal strains distribution after a given stamping process can be obtained using computer aided grid experimental method. In contrast with FLD (Forming Limit Diagram) obtained by the material testing, the measured results of strain distribution can be used to determine the sheet metal’s formability allowing to determine at which point the sheet metal cracks or uneven stretch occurs and other forming defects. The main principle and related theory of this approach are discussed. One automobile panel stamped part as a practical case was studied, the strain distribution of the part after a given stamping process was measured and calculated, a demonstration of how to deal with the results in comparison with FLD to determine and solve forming problems is analyzed.

Abstract With the number of connected-devices increasing tremendously, communication data rates are projected to be at least 10–100X in the 5G/mm-wave (MMW) technology - much higher than the existing 4G LTE connections.[1], [2] To catch up with the trend, novel packaging technology in the MMW frequency range is required, which will address fundamental MMW technical challenges such as high dielectric loss, degradation of quality factors in passives, increased parasitic, dramatically-enhanced electromagnetic interference, and the reduced radiation efficiency of antenna arrays. State-of-the-art approaches being pursued include organic-core substrates that have a low dielectric constant (Dk) and low dissipation factor (Df) such as fluorine based or liquid-crystal polymer (LCP) substrates in order to achieve enhanced antenna performance and low signal dissipations. These organic-based substrate technologies, however, can neither miniaturize packages nor handle precision signal routings that enable high density packages. To address these challenges, attention is focused on Fan-Out Wafer Level Package (FOWLP) technologies, like eWLB, InFO, and SWIFT, where integrated circuits (ICs) are embedded in epoxy molding compound. [3]–[6] Recently, glass-panel embedding (GPE) technology is emerging as an ideal packaging methodology that enables superior performance along with small form factor, ultra-low-loss, high density, ultra-short interconnects, and low cost. [7] These benefits stem from the advantages of using glass which has excellent properties such as ultra-smooth surface for precision redistribution layer (RDL), exceptional dimensional stability for panel-scalability and tailorability of CTE that allow direct board-attach for improved system performance. In addition, utilizing the epoxy molding compounds as encapsulation material allows the GPE package to be thinner and more robust package with small farm factor. Molding of glass cavity panels also helps with the handling of ultra-thin glass which is seen as a bottleneck towards glass based packaging solutions in production. These facilitates enhanced throughput by allowing more cavity cut outs (more coupons) per panel. This paper presents the first demonstration of ultra-thin GPE with sheet type epoxy molding compound (SMC) for 5G/mm-wave applications. First part of this paper discusses the process-flow used in glass-panel embedding with laminated SMC, including chip placement in glass cavities, lamination of SMC, and the reliability of the package architecture. This paper reports on such a demonstration in 60 μm glass substrates with 40 μm thickness SMC. The second part of this paper focuses on low-loss interconnects for 5G/mm-wave applications and presents the process development of signal routings such as transmission lines and microvias in RDLs as well as through-package vias (TPVs) with via-in-via process. The results suggest that the ultra-thin GPE architecture is a promising packaging technology solution for a variety of applications including high-frequency communications and high-performance computing.

Lightweight sandwich panels (LWSP) have been used in various sectors of construction and transportation industries. However, due to the cost and complexity of the manufacturing process, their usage in high level sport equipment has been somewhat neglected. This study investigates the feasibility of using a wood veneer sandwich panel to construct the playing surface of a table tennis table. The effects of material parameters, such as the face sheet thickness, core configuration, core thickness and surface coating, on the dynamic friction coefficient and coefficient of restitution, which ultimately dictate the speed, bounce and spin of the ball, will be examined. All results from characterisation of the LWSP table using the International Table Tennis Federation (ITTF) standards will be compared with those from commercially available tables. The material parameters identified to yield the most consistent and favourable characteristics for a table tennis game will be applied for construction of a full size demonstration table.

In this design study, a model airplane wing, partially constructed from braided composite panels, was made for the purpose of demonstrating the applications of braided composites for aerospace components. Fibres of Kevlar® were braided together along a tubular surface, then subsequently cut and unrolled to form two planar sheets of interlaced yarns that could be laid down in a 3D printed mold to later be coated in resin. The mold consisted of four parts: two female parts to shape the composite wing panels and two male parts to compress the composite. When connected together they form a fused core. A fibre sheet was draped over each female part, and its extraneous edges were folded inward to form a second layer as reinforcement. Each sheet was then laid up with Ecopoxy® resin and allowed to cure while sandwiched between the female mold and its corresponding male component. Upon disassembly of the mold system, a braided composite wing panel had formed upon both halves of the 3D printed core. The external portion of each panel was found to be smooth with few irregularities that could potentially compromise their aerodynamic performance. The mold was constructed to facilitate the process of cold-curing rather than curing at an elevated temperature. For heated cure process, the use of metal would be recommended because it generally deforms negligibly through heating and cooling. A metal mold would also be used to ease the process of debonding from the composite materials. Care should be taken to ensure that fibre orientation is consistent. The results illustrate how a mold can be fabricated to facilitate the process of curing braided composites, and can serve to improve the quality of products that require a higher strength to weight ratio.

The trend in both military and commercial shipbuilding is the increased use of thin steel to reduce weight and improve performance. Complex panel structures have thickness transitions for weight and structural optimization with multiple inserts ranging from 5 to 45 mm. Welding practices developed for thicker plate can result in significant out-of-plane distortion when applied to thin-plate structures. Buckling distortion of complex lightweight panels has resulted in a significant negative effect on manufacturing cost and production throughput, limiting the shipbuilders' ability to produce innovative ship designs. High fitting and welding costs are the consequence of this large welding distortion. This problem is exacerbated as the fairness requirements are tightened. New methods are needed to control distortion when welding thinner materials. To tackle the distortion problems, in 2002 Northrop Grumman Ship Systems initiated a multiyear program to develop distortion-control technology for complex panels. This paper reports the results of a study to develop "best practices" for welding of lightweight structures. Control of welding distortion for thin structures requires control of each welding operation from butt welding of plates through to unit assembly. A general philosophy was applied to minimize welding heat input while maximizing restraint during unit construction. To achieve this, the following techniques were evaluated: increasing restraint during each welding operation, improving fitting practice, weld sequencing, and minimizing welding heat input. Additionally, an active distortion mitigation approach, known as transient thermal tensioning, was investigated for reduction of buckling distortion during thin-panel longitudinal stiffener welding. A series of tests were performed to evaluate various distortion control approaches and to optimize production processes. The culmination of the project will involve demonstrating best practices in the production of thin-steel structures. A plan is also being developed for implementing the most advantageous approaches into production.

Abstract This paper describes the demonstration of a low loss substrate (laminated glass) for high-frequency transmission using a dry film build-up material with low loss tangent (Df). This paper also evaluates filter characteristics and dielectric characteristics of the substrate in the mm-Wave band. The advanced low loss dry film build-up material was newly developed, and applicable to high frequency transmission. This material has a Df of 0.0025 at 10 GHz and also exhibits excellent adhesion and electrical reliability required for advanced dielectric materials. In addition, glass was used as a core material in this paper because of its excellent signal transmission characteristics compared to silicon wafers or organic substrates. To demonstrate the benefit of low loss materials for high frequency transmission, passive components for high frequency filter substrates were fabricated using - 6-inch square thin (0.2mm) glass panel with various build-up materials (Material A with a Df of 0.0025, and Material B with a Df 0.0042 at 10 GHz) laminated. Copper wiring patterns on the dielectric layers were fabricated by a semi-additive process (SAP). Circuit patterns with low pass filters and band pass filters were also fabricated. First, transmission characteristics and characteristic impedances were measured to check the electrical performance. The measured lowest transmission loss of < 1.43 dB at 39 GHz were achieved when Material A was applied as the build-up material. Second, biased-highly accelerated stress test (bHAST) was conducted to evaluate the reliability performance of the substrates with two build-up materials, Material A and a conventional material. The test condition was based on the JEDEC level 2 standard. The substrate with Material A retained good insulation properties over 300 hours of bHAST treatment, demonstrating its excellent insulating performance. In summary, Material A has been shown in this paper to exhibit reduced transmission loss in high-frequency filter substrates at millimeter wave frequencies.

In this present work, a highly damped deployable solar panel module was developed for application in the 3 U CubeSat. The solar panel proposed herein is effective in guaranteeing the structural safety of solar cells under a launch environment owing to the superior damping characteristics achieved using multilayered stiffeners with viscoelastic acrylic tapes. A holding and release action of the solar panel was achieved by a new version of spring-loaded pogo pin-based burn wire triggering mechanism. A demonstration model of high-damping solar panel assembly was fabricated and tested to validate the effectiveness of the design. The holding and release mechanism achieved using a pogo pin was functionally tested through solar panel deployment tests under ambient room temperature and a thermal vacuum environment. The design effectiveness and structural safety of the solar panel module were validated through qualification-level launch and in-orbit environment tests.

We describe a method for post-embedding immunohistochemical demonstration of a wide range of antigens in glycol methacrylate-embedded tissue. Rat spleen and thymus tissues were fixed by immersion in fixatives containing different concentrations of paraformaldehyde, washed in sucrose phosphate buffer, dehydrated in acetone, infiltrated in a glycol methacrylate mixture in which the commonly used softener 2-butoxyethanol was replaced by butaandiol monoacrylate, and embedded. Trypsin was used to re-expose the masked antigenicity. Excellent results were obtained with a panel of monoclonal antibodies (MoAbs) directed against T-cells, B-cells, Ia-positive cells, macrophages, follicular dendritic cells, and leucocyte common antigen-bearing cells. The method described combines exact localization of antigens with optimal tissue morphology.

Ensuring the structural safety of a deployable solar panel under a severe launch vibration environment is one of the important factors for a successful CubeSat mission. A CubeSat’s deployable solar panel proposed in this study is effective to guarantee the structural safety of solar cells by attenuating launch loads owing to the superior damping characteristic achieved by a multilayered stiffener with viscoelastic acrylic tapes. The demonstration model of 3 U CubeSat’s deployable solar panel was fabricated and tested to validate the effectiveness of the proposed design. The basic dynamic characteristics of the solar panel were measured through free-vibration tests according to the various layers of the stiffener. Moreover, the characteristics of the deployed solar panel were measured and investigated under various temperatures to predict its capability under in-orbit operation. The effectiveness of the proposed design for launch vibration attenuation was demonstrated through qualification level sine and random vibration tests.

Abstract Looking at its historical process, the ceramic tile technique that appears in religious, military and administrative buildings as a wall cladding method, has nowadays given way to ceramic wall panels that contribute to the aesthetic values of contemporary architectural structures. This contribution made by the coordinated effort of the architect and the artist via ceramic wall panels, which started to be installed at specifically reserved spots within such contemporary architectural structures, also adds a positive impression on the identity of the structure. These panels, which are considered to be means of surface enrichment and identity attribution, comprise all the stages of forming a work of art. Light, color, circulation, balance, composition, etc. are the factors which stand out as the significant elements within the artwork. Unfortunately, aesthetic and environmental factors are not taken into account within the scope of the rapidly increasing settlement rate worldwide, including our country; and this in turn causes numerous structures in various cities around the world to look alike in shape and form. Still, there are artists, though few in number, who apply structural ceramic elements, which are both environment-friendly and have been in use for thousands of years, with a contemporary understanding. This study aims to elaborate on this issue with a specific focus on the case of the ceramic wall panel titled “Freedom” by Huseyin Ozcelik, executed in 2012 to qualify as a permanent example in which art engages with education; at the Central Library Building of the Near East University, North Cyprus. This application is a completely subjective, and by demonstrating the design and application processes to a group of students, it was aimed to serve educational purposes as well as to empower the structure with an artistic identity. Keywords: ceramic tiles, ceramic wall panels, design.

The recent Intergovernmental Panel on Climate Change (IPCC) report (Climate Change 2013: The Physical Science Basis) states that ‘warming of the climate system is unequivocal’, and that ‘it is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century’. The IPCC report follows a common trend attributing increasing anthropogenic greenhouse gas emissions as the cause of this climate change. Carbon dioxide (CO2), primarily from the combustion of fossil fuels for energy, is the most common greenhouse gas emitted by human activities. Reduction of greenhouse gas emission, particularly CO2 to the atmosphere, is therefore a key environmental issue facing Australia and the world.

The results show that environmental efficiency improved with industrial transfer demonstration zones by boosting the ability to innovate, government’s expenditure on the environment, and regulatory frameworks for the environment. The findings reflect a significant increase in the GDP of the triennial industry while an insignificant decrease. Hence, to promote all-inclusive first-rate development, regional collaborative must be ensured during industrial transformation demonstration.

Annotation:

Onsets of binary events are often of interest to political scientists, whether they be regime changes, the occurrence of civil war, or the signing of bilateral agreements, to name a few. Often researchers transform the binary event outcome of interest, by setting ongoing years to zero, to create a variable which measures the onset of the event. While this may seem an intuitive way to go about estimating models where onset is the outcome of interest, it results in two problems that can affect substantive inferences. First, it creates two qualitatively different meanings for a unit time period to have a zero, which estimators are unable to “know.” Second, it ignores the possibility that variables may have differing effects upon binary event onsets and durations. This article explores how much this transformation can harm our substantive inferences by analytically demonstrating the resulting bias and the use of Monte Carlo experiments, as well as offering recommendations to avoid these problems. I also conduct a sensitivity analysis on the determinants of civil war onset to examine how substantive inferences are affected by this issue. In doing so, I find that there is considerable difference in the size of estimated coefficients and whether a variable is considered a robust determinant of civil war.

Abstract This paper demonstrates a next generation high-performance 3D packaging architecture with smaller form factor, excellent electrical performance and reliability for heterogeneous integration. High density Logic-HBM integration, today, is built predominantly using interposers which are fundamentally limited in assembly pitch and interconnect lengths, and they also are expensive as the package sizes increase. On the other hand, high-frequency applications continue to use laminates which are again limited by package size and ability to integrate many components. WLFO promises better performance and form factor at lower costs, but current WLFO packages are mold-based and hence are limited to small packages. This paper presents the first demonstration of 3D Glass Panel Embedding (GPE) technology for high-performance large package applications involving heterogeneous integration. The tailorable CTE of glass allows a reliable direct board SMT of large GPE packages that not only benefits form factor and signal speed, but also provides radical benefits to power delivery. Unlike interposers and silicon bridges, GPE packages are not bump limited and can support BEOL-like I/O densities with Silicon-like RDL at much lower costs. The fundamental limitations like die-shift and poor dimensional stability of current organic WLFO packages are addressed by parametric process improvements to reduce die-shift to <2 um while also improving the RDL surface planarity for high-yielding fine-line structures. This paper describes the fabrication process for 3D GPE, leading to demonstration of a technology using embedding of chips with all-Cu interconnections at 40um I/O pitch while also enabling double-side assembly of chips to achieve 3 levels of device integration.

High-density logic-memory integration, today, is built predominantly using interposers which are fundamentally limited in assembly pitch and interconnect lengths, and they also are expensive as the package sizes increase. On the other hand, high-frequency applications continue to use laminates which are also limited by package size and ability to integrate many components. Wafer-level fan-out (WLFO) packaging promises better performance and form factor at lower costs, but current WLFO packages are mold-based and hence are limited to small packages. This article presents a 3D packaging technology using glass panel embedding (GPE) for high-performance with potential for large body size heterogeneous integration applications. The tailorable coefficient of thermal expansion of glass allows a reliable direct board attach of large GPE packages that not only benefits the form factor and signal speed but also provides radical benefits to power delivery. Unlike interposers and silicon bridges, GPE packages are not bump-limited and can support I/O densities comparable with backend-of-line with silicon-like redistribution wiring at much lower costs. The fundamental limitations such as die shift and poor dimensional stability of current organic WLFO packages are addressed by parametric process improvements to reduce die shift to <2 μm while also improving the RDL surface planarity for high-yielding fine-line structures and integrating through glass via (TGV) in the fan-out region for 3D packaging. This article describes the fabrication process for 3D GPE, leading to demonstration of a technology using embedding of chips with all-Cu interconnections at 40-μm I/O pitch with TGVs at 300-μm pitch, thus enabling double-side RDL and assembly of chips to achieve three levels of device integration.

Transmission constraints often limit the flow of electricity in a regional transmission network leading to strong interaction effects across different geographically distributed points within the system. In modern wholesale electricity markets, these transmission constraints lead to spatial patterns within the nodal electricity spot prices. This study exploits these spatial patterns to better predict spot prices within a wholesale electricity market. More specifically, we use the latest spatial panel data econometric models to compare within-sample and out-of-sample forecasts against nonspatial panel data models. The spatial panel data approach is explained by demonstrating a simple network optimization model. We find that a dynamic, spatial panel data model provides the best predictions within a forecasting error context. Our results may suggest that the spatial autocorrelation between node prices extends beyond the current market-defined zonal boundaries, which calls into question whether the zonal boundaries accurately reflect the congestion boundaries within the system.

A demonstration model of a printed circuit board-based solar panel stiffened by a high-pressure fiberglass-laminated G10 material was fabricated and tested to validate the effectiveness of the design and functionality of the mechanism under various test conditions. The structural safety of the solar panel combined with the mechanism in a launch vibration environment was verified through sine and random vibration tests at qualification level.

Abstract. The growing use of Rational Emotive Behavior Therapy (REBT) in performance contexts (e.g., business, sport) has highlighted the absence of a contextually valid and reliable measure of irrational beliefs. This paper reports the development and initial validation of the Irrational Performance Beliefs Inventory (iPBI). The iPBI was developed to provide a validated measure of the four core irrational beliefs of REBT theory. Item development was completed in three stages comprising two expert panels and one novice panel, reducing and refining 176 items to 133. Then, exploratory and confirmatory factor analyses were used to refine the measure and reduce the number of items. A total of 665 business professionals completed the 133-item scale, alongside an established measure of irrational beliefs and a measure of negative emotion. A 28-item measure was developed (the iPBI) that showed an acceptable fit to the four-factor REBT structure. The iPBI correlated well with the established irrational beliefs measure, and with anxiety, depression, and anger, demonstrating concurrent and predictive validity. Further validation efforts are required to assess the validity and reliability of the iPBI in alternative samples in other performance-related contexts.

Beef Cattle have a role as saving for farmers to continue their business, although not profitable based on business analysis. Therefore, the right strategy is needed according to the problems of both the culture and the resources of farmers. The community service activity was conducted in a beef cattle farmer groups as cattle breeding for calf production, namely, are Mergo Andini Makmur and Sumber Ayu in Sleman Regency. The beef cattle productivity in the two groups is not good, S/C is more than twice, even up to four times, postpartum estrus is more than one year, and calving interval is more than 2 years. The beef cattle farmer groups have already diversified their business, which is the processing of manure and waste product of cattle, but not yet optimal. Community service is carried out to improve reproductive performance of cattle through the providing of a superior bull for bull stimulation, counseling, assistance in the prevention of worm infections, and demonstrations of compost and feed quality production. The first stage is preparation, including consolidation with the member farmer groups, followed by the socialization of the activity program. The next stage of implementation, by conducting reproductive and breeding management counseling, cattle health management, feed processing and management, and compost production. The result of the implementation of a bull stimulation for one month is based on the emergence of estrus (more than 50%) following by a conception rate (33.33%) of the cows population, and the level of participatory farmers. The demonstration of the fermented straw feed and compost is also implemented as a supporting activity.

This paper describes the design, fabrication, and characterization of a two-metal layer RDL structure at 40 um pitch on thin glass interposers. Such an RDL structure is targeted at 2.5D glass interposer packages to achieve up to 1 TB/s die-to-die bandwidth and off-interposer data rates greater than 400 Gb/s, driven by consumer demand of online services for mobile devices. Advanced packaging architectures including 2.5D and 3D interposers require fine line lithography beyond the capabilities of current organic package substrates. Although silicon interposers fabricated using back-end-of-line processes can achieve these RDL wiring densities, they suffer from high electrical loss and high cost. Organic interposers with high wiring densities have also been demonstrated recently using a single sided thin film process. This paper goes beyond silicon and organic interposers in demonstrating fine pitch RDL on glass interposers fabricated by low cost, double sided, and panel-scalable processes. The high modulus and smooth surface of glass helps to achieve lithographic pitch close to that of silicon. Furthermore, the low loss tangent of glass helps in reducing dielectric losses, thus improving high-speed signal propagation. A semi-additive process flow and projection excimer laser ablation was used to fabricate two-metal layer RDL structures and bare glass RDL layers. A minimum of 3 um lithography and 20 um mico-via pitch was achieved. High-frequency characterization of these RDL structures demonstrated single-ended insertion losses of −0.097 dB/mm at f = 1 GHz and differential insertion losses of −0.05 dB/mm at f = 14 GHz.
