Thermal Resistance Analysis of a Multi-Stack Flip Chip 3-D Package

This paper evaluates the thermal performance of a newly developed multi-stack flip chip package using the finite element method. The effect of the major parameters, identified as the solder material, the solder joint pitch, the solder joint height and the pad diameter on the thermal performance of the package is studied. Based on the finite element results, a lumped model is developed which is capable to give quick and promising results of the junction temperatures of the package for different solder joint configuration.
The C−159T polymorphism in the CD14 promoter is associated with serum total IgE concentration in atopic Chinese children

Activation of macrophages through CD14 by microbes is crucial in inducing immunity by type 1 T helper cells. A C‐to‐T polymorphism at position −159 of CD14 was associated with serum total IgE level in Caucasians but not in Japanese subjects. The objective of this study is to determine whether this polymorphic marker is associated with atopy and asthma phenotypes in Chinese children. Restriction fragment length polymorphism was used to characterize CD14/−159 genotypes. Microparticle immunoassay was used to measure serum total IgE level; fluorescent enzyme immunoassay was performed to measure serum concentrations of specific IgE to aeroallergens; and enzyme‐linked immunosorbent assay was used to measure serum levels of soluble CD14 (sCD14). Lung function in asthmatics was assessed by spirometry. Two hundred and fifty‐eight patients and 92 control children were recruited. Their mean serum total IgE concentrations were 331 and 74 kIU/l, respectively (p < 0.0001). Atopy, defined as the presence of at least one allergen‐specific IgE in serum, was found in 220 (85%) patients and in 41 (45%) controls (p < 0.0001). Serum sCD14 levels were significantly associated with CD14/−159 genotypes (p = 0.004). Atopic subjects with CC genotype in CD14/−159 had the highest serum total IgE levels compared with CT and TT genotypes, with the respective mean values being 661, 427 and 380 kIU/l (p = 0.015). Similarly, a higher proportion of subjects with CC genotype had increased serum total IgE concentration (p = 0.039). This polymorphic marker was not associated with asthma or aeroallergen sensitization in our cohort. Our results suggest that the C−159T of CD14 was associated with serum total IgE concentration in atopic Chinese children.
Stance Classiﬁcation with Target-Speciﬁc Neural Attention Networks

Stance classiﬁcation, which aims at detecting the stance expressed in text towards a speciﬁc target, is an emerging problem in sentiment analysis. A major difference between stance classiﬁcation and traditional aspect-level sentiment classiﬁcation is that the identiﬁcation of stance is dependent on target which might not be explicitly mentioned in text. This indicates that apart from text content, the target information is important to stance detection. To this end, we propose a neural network-based model, which incorporates target-speciﬁc information into stance classiﬁcation by following a novel attention mechanism. In speciﬁc, the attention mechanism is expected to locate the critical parts of text which are related to target. Our evaluations on both the English and Chinese Stance Detection datasets show that the proposed model achieves the state-of-the-art performance.

A wide-band antenna, to be used in mobile communication systems and wireless local area networks applications, has been selected. An antenna prototype has been designed, fabricated and tested. Good agreement has been obtained between theoretical and experimental results.
In Situ Investigation of Current Transport Across Pt/n-Si (100) Schottky Junction During 100 $\hbox{MeV Ni}^{+7}$  Ion Irradiation

In situ current-voltage (<i>I</i>-<i>V</i>) analyses of Pt/n-Si (100) Schottky barrier (SB) diode are carried out during 100 MeV Ni<sup>+7</sup> ion beam irradiation. The effect of MeV ion beam on the electrical parameters like ideality factor (η) and SB height (SBH) (φ<sub>B</sub>) of SB diode is investigated. For lower fluences, SBH decreases from its preradiation value, but there is almost no change in SBH for ion fluences ranging from 5×10<sup>11</sup> to 1×10<sup>13</sup> ions/cm<sup>2</sup>. The reverse current is increased by about two orders of magnitude at the fluence of 5×10<sup>13</sup> ions/cm<sup>2</sup> which corresponds to an exposure of a few tens of years in low earth orbit. The radiation-induced diffusion of Schottky metal into the semiconductor and creation of trap centers at the metal-semiconductor interface are supposed to be the most plausible mechanisms for these deviations in SB diode characteristics.

Echo planar imaging of isolated perfused rat hearts at 4.7 T: A comparison of Langendorff and working heart preparations

The implementation of echo planar imaging at 4.7 T is demonstrated using a home‐built gradient and radiofrequency assembly. The application of such a technique to the study of the isolated perfused rat heart is demonstrated. Langendorff and working heart perfusion preparations are compared and changes in the left ventricular volume shown are to be much larger in the working heart preparation. Such a methodology is expected to provide a useful model for the study of cardiac function and dynamics in the normal and diseased states under controlled perfusion conditions. © 1990 Academic Press, Inc.
Influences of the Campus Experience on the Ethnic Identity Development of Students of Color

This qualitative research study examined ethnic identity development among underrepresented students of color at a selective, research intensive, predominantly White university. The objective focused on influences of the campus experience on students’ ethnic identity development when they entered and as they prepared to graduate from college. Students were asked to reflect on how development of their ethnic identity intersected with outcomes as critical thinking, communication skills, and sense of competence. Findings include an increased learning about one’s ethnic group has cognitive and noncognitive benefits. Students felt further development of their ethnic identity had a considerable, positive impact on their sense of competence, sense of belonging, interpersonal relationships, and commitments. Institutional and policy implications are discussed.
AUTOMATIC DETECTION AND CORRECTION OF SEGMENTATION LEAKS IN MEDICAL IMAGES

We present a new method for the detection and correction of segmentation leaks in volumetric medical images. Segmentation leaks occur when the segmentation volume expands outside the actual target structure boundary into neighboring structures. Our method identiﬁes the segmentation leak basis boundary by gradient magnitude likelihood classiﬁcation, ﬁts a surface to the leak basis boundary, and separates the leak from the target structure after ﬁnding their common boundary. Our method is automatic, does not rely on prior information, and is independent of the initial segmentation method. Experimental evaluation on 139 segmentations of kidneys and abdominal aortic aneurysms from CT scans from two common segmentation methods yield an improvement of 56.8% (std=15.4) and 49.4% (std=19.5) in the mean surface distance and the volume overlap error between the initial and the corrected segmentations.

Contudo, a grande quantidade de informacoes gerenciais propiciadas superaram os entraves encontrados.
Cluster head load distribution scheme for wireless sensor networks

This paper proposes an optimal load distribution scheme in cluster head and cluster members nodes for wireless sensor networks (WSN). Proposed load distribution model is based on associative clustering model, guided by residual energy and load of the sensor nodes in a cluster. Energy hole can be avoided in this scheme by uniform load distribution in the clusters. An efficient data routing is also performed through the clusters to the base station using multi-hop technique. Simulation results show that our proposed scheme outperforms the existing algorithms in terms of the network lifespan, and optimal load distribution. Time efficient routing is also established within a cluster.
Modeling of NBTI time kinetics and T dependence of VAF in SiGe p-FinFETs

NBTI in Replacement Metal Gate (RMG) High-K Metal Gate (HKMG) SiGe p-FinFETs is modeled. Time kinetics for DC and AC stress and recovery, temperature (T) dependence of voltage acceleration factor (VAF), and impact of Ge% and N% are quantified. Benchmarking is done with Si p-FinFETs, and process (Ge%, N%) dependence is explained by TCAD and band structure calculations.
Investigation of Random Telegraph Noise in the Dark Current of Germanium Waveguide Photodetector

Dark current variations in the germanium waveguide photodetector were investigated. Contributing to the time dependent dark current variations, random telegraph noise (RTN) was observed and studied for the first time. The RTN at different reverse biases and temperatures were measured. By analyzing the capture and emission time constants, the single trap that was responsible for RTN was estimated to be around 18 nm from the interface between the N ++ and the intrinsic region. The trap energy levels at different reverse biases were also extracted and the trapping and detrapping dynamics were explained. Through this procedure, the single trap that may lead to device failure can be detected and characterized without destroying the well-fabricated devices.
Matrix Metalloproteinase Content and Activity in Low-Platelet, Low-Leukocyte and High-Platelet, High-Leukocyte Platelet Rich Plasma (PRP) and the Biologic Response to PRP by Human Ligament Fibroblasts

Background: Recent work has shown the presence of catabolic cytokines in platelet-rich plasma (PRP), but little is known about endogenous catabolic proteases such as matrix metalloproteinases (MMPs). Hypothesis/Purpose: To quantify MMP content in 2 commercially available PRP preparation systems: Arthrex Double Syringe System autologous conditioned plasma (ACP) and Biomet GPS (GPS). The hypothesis was that MMPs are actively secreted from PRP immediately after preparation. Study Design: Controlled laboratory study. Methods: PRP was prepared using either ACP (low platelet, low leukocyte) or GPS (high platelet, high leukocyte). MMP-2, MMP-3, and MMP-9 concentrations were measured using multiplex enzyme-linked immunosorbent assays for up to 6 days in 2 donors, and MMP activity was measured in 3 donors using kinetic activity kits able to detect the enzymatic cleavage of a fluorogenic peptide. Human ligament fibroblasts were cultured and exposed to both ACP and GPS from 1 donor each. MMP-2, -3, and -9 concentrations were assayed in culture media at 24 and 48 hours after exposure. Results: GPS exhibited higher total MMP-2, -3, and -9 concentrations for up to 144 hours of release, while ACP had higher platelet-normalized MMP-2 and MMP-3 concentrations. GPS had significantly higher total and endogenous MMP-2 activity (P = .004 and .014, respectively), MMP-3 activity (P = .020 and .015, respectively), and MMP-9 activity (P = .004 and .002, respectively) compared with ACP. Once normalized to platelet count, differences in MMP activity were not significant between ACP and GPS. Compared with controls, cells stimulated with interleukin-1 beta (IL-1β) and treated with ACP showed significantly higher fold changes of MMP-2 (P = .001) and MMP-3 (P = .003) concentrations at 24 hours than did cells treated with GPS. Total MMP-9 content was higher in the media of GPS-treated, IL-1β–stimulated cells compared with ACP-treated cells (P = .001). At 48 hours, IL-1β–stimulated cells treated with GPS exhibited higher fold changes of MMP-2 concentration (P = .002) compared with controls, but no difference in MMP-3 concentration was found. At 48 hours, there was a significantly higher concentration of MMP-9 in the cell culture media of ACP-treated cells compared with GPS-treated cells (P = .003). Conclusion: PRP prepared as both ACP and GPS contains MMP-2, -3, and -9, which is released over a period of at least 6 days. Furthermore, a large proportion of these MMPs are in their active form, and MMP activity is dependent on platelet count within the PRP preparation. Once exposed to ligament fibroblasts, both ACP and GPS cause the fibroblasts to release MMPs, most notably 24 hours after PRP exposure, and this release is dependent on prior IL-1β stimulation. Clinical Relevance: The results of this study demonstrate that PRP therapy delivers ng/mL-range concentrations of catabolic proteases, which could perpetuate inflammation and inhibit tissue healing.
Is the Spelling of "Baalis" in Jeremiah 40:14 a Mutilation?

A recent paper by William H. Shea published in AUSS suggests that the biblical spelling of Baalis (baCalis), the Ammonite king mentioned in Jer 40:14, was probably a deliberate mutilation of the Ammonite spelling, ba CalyiSCa (or, bacalyaSa ') found on a seal impression discovered at Tell el-=Umeiri during the 1984 Andrews University archaeological expedition to that si te.1 (This seal impression will be published by me in a forthcoming issue of the Biblical Archaeologist.) Shea's opinion is that Jeremiah himself changed the spelling in order "to deny a predication about a foreign god. "* In this case, the name would mean "Baal is salvation," "Baal is savior," or "Baal savesu-all of which would be distasteful theological ideas to an orthodox Yahwist. Prior to my detailed work on the impression I, too, held this view concerning the origin of the Jeremiah spelling. It had been suggested by Robert G. Boling after he had examined, at my behest, F. M. Cross's article on the Siran Bottle inscription, in which Cross lists the known Ammonite kings.3 This view became, in fact, the consensus view among all staff members during and immediately following the excavation. However, during my preparation of the impression for publication, several indications suggested that there was no mutilation. First of all, a rather general observation may be made: In writing
Computational foot modeling for clinical assessment

Esta Tesis desarrolla un modelo de elementos finitos del pie humano completo y detallado en tres dimensiones para avanzar hacia una simulacion computacional mas precisa que proporcione informacion realista y relevante para la practica clinica. Desde el punto de vista ingenieril, el pie humano es una compleja estructura de pequenos huesos, soportados por fuertes ligamentos y controlada por una red de musculos y tendones con una capacidad de respuesta mecanica excepcional. La barrera actual en la simulacion computacional del pie es la inclusion de estas estructuras musculotendinosas en los modelos. Para avanzar en esta direccion, se crea un modelo de elementos finitos del pie completo y detallado con geometria real de la estructura interna diferenciando hueso cortical y esponjoso, tendon, musculo, cartilago y grasa. Se realizan ensayos experimentales de los tendones del pie y la suela plantar para determinar sus propiedades materiales y estructurales y caracterizar computacionalmente su comportamiento mecanico no lineal. Estos avances estan orientados hacia la mejora de la representacion geometrica y caracterizacion del tejido de los componentes internos del pie. El modelo desarrollado en esta Tesis puede usarse en el campo de la biomecanica en areas de ortopedia, lesiones, tratamiento, cirugia y deporte. La investigacion esta estructurada por capitulos en los cuales se desarrollan pequenos avances hacia el objetivo principal de la Tesis al mismo tiempo que se aplica el potencial de estos avances a casos particulares. Estas contribuciones parciales en el area de los ensayos experimentales son: la determinacion de un completo conjunto de datos de las propiedades mecanicas de los tendones del pie, la definicion de un criterio para cuantificar las regiones de la curva de tension-deformacion del tendon y el analisis de la respuesta a compresion de la suela plantar en funcion de la posicion. Y, en el area de la biomecanica clinica las contribuciones son: la investigacion de un parametro del esqueleto como factor etiologico del hallux valgus, el estudio de sensibilidad de la fuerza de los cinco mayores tendones estabilizadores, el analisis cuasi-estatico de la fase de apoyo de la marcha y el estudio del mecanismo de absorcion de la fuerza de impacto del pie durante la carrera descalzo a diferentes angulos de impacto.
Parameters and Tectonic Implications of Aftershocks of the M w 7 . 6 Bhuj Earthquake of 26 January 2001

We present and discuss the spatial distribution of more than 1000 aftershocks of the largest continental intraplate earthquake to occur during the modern seismological period. The data were recorded on a network of eight portable digital seismographs deployed for 3 weeks starting 17 days after the mainshock. We have calculated high-quality single-event locations, based on a 1D velocity model determined for the region for earthquakes with magnitudes between 2 and 5. Aftershock locations reveal activity concentrated on a nearly east-striking, south-dipping plane, trapezoidal in outline. The active zone tapers from about 45 km along strike at the shallow end, which is about 5 km deep, to no more than 25 km long at a depth of 35 km. The total rupture area was about 1300 km. We estimate the static stress drop of the mainshock at 16 2 MPa. Aftershocks extend nearly through the entire crust, with concentrations in the lower crust at about 26 km and in the upper crust at about 10 km. The fault that ruptured was not mapped at the surface and not known to have been active prior to the 2001 earthquake. The aftershock data are consistent with the Bhuj earthquake resulting from reactivation in contraction of a fault formed under extension within a failed rift.

Comments on 'A module generator for optimized CMOS buffers'

For the original article see ibid., vol.9, no.10, p.1028-46 (1990). In the above-titled paper A.J. Al-Khalili et al. claim that the expression derived by the commenters (1987) for the short-circuit energy dissipation per transition for a CMOS inverter while the n-channel transistor is discharging the load capacitor is not correct, and they suggest that some mistakes were made during the integration. The commenters point out that a rederivation showed that their expression is correct, and even if it is given for equal p- and n-channel transistors, it can easily be generalized to arbitrary p- and n-channel transistor sizes. >
Cumate-Inducible Gene Expression System for Sphingomonads and Other Alphaproteobacteria

ABSTRACT Tunable promoters represent a pivotal genetic tool for a wide range of applications. Here we present such a system for sphingomonads, a phylogenetically diverse group of bacteria that have gained much interest for their potential in bioremediation and their use in industry and for which no dedicated inducible gene expression system has been described so far. A strong, constitutive synthetic promoter was first identified through a genetic screen and subsequently combined with the repressor and the operator sites of the Pseudomonas putida F1 cym/cmt system. The resulting promoter, termed PQ5, responds rapidly to the inducer cumate and shows a maximal induction ratio of 2 to 3 orders of magnitude in the different sphingomonads tested. Moreover, it was also functional in other Alphaproteobacteria, such as the model organisms Caulobacter crescentus, Paracoccus denitrificans, and Methylobacterium extorquens. In the noninduced state, expression from PQ5 is low enough to allow gene depletion analysis, as demonstrated with the essential gene phyP of Sphingomonas sp. strain Fr1. A set of PQ5-based plasmids has been constructed allowing fusions to affinity tags or fluorescent proteins.
Robust Fractional Order Proportional, Integral and Derivative Stabilizer for Power Systems

This paper focuses on the application of a robust Fractional Order PID (FOPID) stabilizer tuned by Genetic Algorithm (GA). The system’s robustness is assured through the application of Kharitonov’s theorem to overcome the effect of system parameter’s changes within upper and lower limits. The FOPID stabilizer has been approximated during the optimization using the Oustaloup’s approximation for fractional calculus and using the “nipid” toolbox of Matlab during simulation. The objective is to keep robust stabilization with maximum achievable degree of stability against system's uncertainty. This optimization will be achieved with the proper choice of the FOPID stabilizer’s parameters (kp, ki, kd, l, and d) as discussed later in this article. The optimization has been done using the GA which limits the boundaries of the tuned parameters within the permissible region. The calculations have been applied to a single machine infinite bus (SMIB)power system using Matlab and Simulink. The results show superior behavior of the proposed stabilizer over the traditional PID.
