25.2 A 1.2V 8Gb 8-channel 128GB/s high-bandwidth memory (HBM) stacked DRAM with effective microbump I/O test methods using 29nm process and TSV

Increasing demand for higher-bandwidth DRAM drive TSV technology development. With the capacity of fine-pitch wide I/O [1], DRAM can be directly integrated on the interposer or host chip and communicate with the memory controller. However, there are many limitations, such as reliability and testability, in developing the technology. It is advantageous to adopt a logic-interface chip between the interposer and stacked-DRAM with thousands of TSV. The logic interface chip in the base level of high-bandwidth memory (HBM) decreases the CIO, repairs the chip-to-chip connection failure, and supports better testability and improves reliability.
The tech writer's survival guide: A comprehensive handbook for aspiring technical writers [Book Review]

Book Publisher: New York: Checkmark Books/ An Imprint of Facts on File, Inc., 2001, 269 pp. with index. The technical communication profession is more than 50 years old, so it is somewhat surprising that only a few book publishers provide sources of career information and advice for curious readers who are considering entering the profession. Four books currently in print provide good general introductions to technical writing as a career choice: Opportunities in Technical Writing Careers [1], a comprehensive but slightly outdated guide; Technical Writing for Dummies [2], a wide-ranging book with a strong emphasis on business communication; The Complete Idiot’s Guide to Technical Writing [3], an effective introduction to technical writing (for those who like the breezy writing style associated with the Idiot’s imprint) with emphasis on software documentation; and Janet Van Wicklen’s book, first published in 1992 with the title The Tech Writing Game [4], now republished in a revised edition as The Tech Writer’s Survival Guide.
Automatic Three-Dimensional Cephalometric Annotation System Using Three-Dimensional Convolutional Neural Networks

Background: Three-dimensional (3D) cephalometric analysis using computerized tomography data has been rapidly adopted for dysmorphosis and anthropometry. Several different approaches to automatic 3D annotation have been proposed to overcome the limitations of traditional cephalometry. The purpose of this study was to evaluate the accuracy of our newly-developed system using a deep learning algorithm for automatic 3D cephalometric annotation. Methods: To overcome current technical limitations, some measures were developed to directly annotate 3D human skull data. Our deep learning-based model system mainly consisted of a 3D convolutional neural network and image data resampling. Results: The discrepancies between the referenced and predicted coordinate values in three axes and in 3D distance were calculated to evaluate system accuracy. Our new model system yielded prediction errors of 3.26, 3.18, and 4.81 mm (for three axes) and 7.61 mm (for 3D). Moreover, there was no difference among the landmarks of the three groups, including the midsagittal plane, horizontal plane, and mandible (p>0.05). Conclusion: A new 3D convolutional neural network-based automatic annotation system for 3D cephalometry was developed. The strategies used to implement the system were detailed and measurement results were evaluated for accuracy. Further development of this system is planned for full clinical application of automatic 3D cephalometric annotation.
Balanced generalized handcuffed designs

Abstract The definition of balanced generalized handcuffed designs (BHD) is of course more specific than that of the generalized handcuffed designs that we introduced in 1987. In the first part of this paper, we present a particular property of a BHD, which is not necessarily that of a generalized handcuffed design. Then, we provide the reader with a general procedure that enables one to obtain such designs, and is called a ‘difference method’. We also show how this difference method can be made more useful in the case where the set V on which a BHD is constructed is the residue classes of integers mod V . The third part of this paper deals with the problem of the existence of a BHD; and a solution is given for a particular case. We assume that the method applied for solving this problem will allow for the constructing of many more theorems analogous to Theorem 3.
Survival and complication rates of combined tooth-implant-supported fixed partial dentures.

OBJECTIVES
The objective of this study has been to review the incidence of biological and technical complications in case of tooth-implant-supported fixed partial denture (FPD) treatments on the basis of survival data regarding clinical cases.


MATERIAL AND METHODS
Based on the treatment documentations of a Bundeswehr dental clinic (Cologne-Wahn German Air Force Garrison), the medical charts of 83 patients with tooth-implant-supported FPDs were completely recorded. The median follow-up time was 4.73 (time range: 2.2-8.3) years. In the process, survival curves according to Kaplan and Meier were applied in addition to frequency counts.


RESULTS
A total of 84 tooth-implant (83 patients) connected prostheses were followed (132 abutment teeth, 142 implant abutments (Branemark, Straumann). FPDs: the time-dependent illustration reveals that after 5 years, as many as 10% of the tooth-implant-supported FPDs already had to be subjected to a technical modification (renewal (n=2), reintegration (n=4), veneer fracture (n=5), fracture of frame (n=2)). In contrast to non-rigid connection of teeth and implants, technical modification measures were rarely required in case of tooth-implant-supported FPDs with a rigid connection. There was no statistical difference between technical complications and the used implant system. Abutment teeth and implants: during the observation period, none of the functionally loaded implants (n=142) had to be removed. Three of the overall 132 abutment teeth were lost because of periodontal inflammation. The time-dependent illustration reveals, that after 5 years as many as 8% of the abutment teeth already required corresponding therapeutic measures (periodontal treatment (5%), filling therapy (2.5%), endodontic treatment (0.5%)). After as few as 3 years, the connection related complications of implant abutments (abutment or occlusal screw loosening, loss of cementation) already had to be corrected in approximately 8% of the cases. In the utilization period there was no screw or abutment fracture.


CONCLUSION
Technical complications of implant-supported FPDs are dependent on the different bridge configurations. When using rigid functional connections, similarly favourable values will be achieved as in case of solely implant-supported FPDs. In this study other characteristics like different fixation systems (screwed vs. cemented) or various implant systems had no significant effect to the rate of technical complications.
Effective Learning in Dynamic Environments by Explicit Context Tracking

Daily experience shows that in the real world, the meaning of many concepts heavily depends on some implicit context, and changes in that context can cause radical changes in the concepts. This paper introduces a method for incremental concept learning in dynamic environments where the target concepts may be context-dependent and may change drastically over time. The method has been implemented in a system called FLORA3. FLORA3 is very exible in adapting to changes in the target concepts and tracking concept drift. Moreover, by explicitly storing old hypotheses and re-using them to bias learning in new contexts, it possesses the ability to utilize experience from previous learning. This greatly increases the system's eeectiveness in environments where contexts can reoccur periodically. The paper describes the various algorithms that constitute the method and reports on several experiments that demonstrate the exibility of FLORA3 in dynamic environments.
Long-term effects of cocaine experience on neuroplasticity in the nucleus accumbens core of addiction-prone rats

Repeated exposure to drugs of abuse is associated with structural plasticity in brain reward pathways. Rats selectively bred for locomotor response to novelty differ on a number of neurobehavioral dimensions relevant to addiction. This unique genetic animal model was used here to examine both pre-existing differences and long-term consequences of repeated cocaine treatment on structural plasticity. Selectively bred high-responder (bHR) and low-responder (bLR) rats received repeated saline or cocaine injections for 9 consecutive days. Escalating doses of cocaine (7.5, 15 and 30 mg/kg) were administered on the first (day 1) and last (day 9) days of treatment and a single injection of the intermediate dose (15 mg/kg) was given on days 2-8. Motor activity in response to escalating doses of cocaine was compared on the first and last days of treatment to assess the acute and sensitized response to the drug. Following prolonged cocaine abstinence (28 days), spine density was examined on terminal dendrites of medium spiny neurons in the nucleus accumbens core. Relative to bLRs, bHRs exhibited increased psychomotor activation in response to both the acute and repeated effects of cocaine. There were no differences in spine density between bHR and bLR rats under basal conditions or following repeated saline treatment. However, spine density differed markedly between these two lines following prolonged cocaine abstinence. All spine types were decreased in cocaine-treated bHRs, while only mushroom spines were decreased in bLRs that received cocaine. Changes in spine density occurred specifically near the branch point of terminal dendrites. These findings indicate that structural plasticity associated with prolonged cocaine abstinence varies markedly in two selected strains of rats that vary on numerous traits relevant to addiction. Thus, genetic factors that contribute to individual variation in the behavioral response to cocaine also influence cocaine-induced structural plasticity.
Quality of life of colorectal cancer patients in certified centers versus non-certified hospitals.

BACKGROUND
Since 2006, in Germany colorectal cancer patients can be treated in certified colorectal cancer centers. The aim of this explorative study was to investigate whether there are differences in the quality of life (QoL) of colorectal cancer patients who were treated in certified versus noncertified centers.


PATIENTS AND METHODS
A total of 284 colorectal cancer patients participated in the study: 184 patients from certified colorectal cancer centers and 100 patients from noncertified centers. Data on QoL (using the Quality of Life Questionnaire of the European Organization for Research and Treatment of Cancer (EORTC-QLQ C30)), patient satisfaction, mental distress and sociodemographic data were assessed with a questionnaire in a written survey after the hospital stay. The moderating influence of patientrelated characteristics (e.g. age, sex, patient satisfaction, and psychological distress) and cancerrelated factors (Union internationale contre le cancer (UICC) stage) were tested.


RESULTS
On a descriptive level, patients from noncertified centers had a higher QoL in 5 subdimensions (higher physical and role functioning and less insomnia, appetite loss and financial difficulties). After adjustment, only 2 differences remained significant: physical functioning (p < 0.01) and role functioning (p = 0.02).


CONCLUSION
Structural improvements in the oncological care are not necessarily reflected in a better QoL of the patients treated in certified colorectal cancer centers. The findings are discussed in the context of the applied study design.
Retweet or not?: personalized tweet re-ranking

With Twitter being widely used around the world, users are facing enormous new tweets every day. Tweets are ranked in chronological order regardless of their potential interestedness. Users have to scan through pages of tweets to find useful information. Thus more personalized ranking scheme is needed to filter the overwhelmed information. Since retweet history reveals users' personal preference for tweets, we study how to learn a predictive model to rank the tweets according to their probability of being retweeted. In this way, users can find interesting tweets in a short time. To model the retweet behavior, we build a graph made up of three types of nodes: users, publishers and tweets. To incorporate all sources of information like users' profile, tweet quality, interaction history, etc, nodes and edges are represented by feature vectors. All these feature vectors are mapped to node weights and edge weights. Based on the graph, we propose a feature-aware factorization model to re-rank the tweets, which unifies the linear discriminative model and the low-rank factorization model seamlessly. Finally, we conducted extensive experiments on a real dataset crawled from Twitter. Experimental results show the effectiveness of our model.
A Reusable PZT Transducer for Monitoring Initial Hydration and Structural Health of Concrete

During the construction of a concrete structure, strength monitoring is important to ensure the safety of both personnel and the structure. Furthermore, to increase the efficiency of in situ casting or precast of concrete, determining the optimal time of demolding is important for concrete suppliers. Surface bonded lead zirconate titanate (PZT) transducers have been used for damage detection and parameter identification for various engineering structures over the last two decades. In this work, a reusable PZT transducer setup for monitoring initial hydration of concrete and structural health is developed, where a piece of PZT is bonded to an enclosure with two bolts tightened inside the holes drilled in the enclosure. An impedance analyzer is used to acquire the admittance signatures of the PZT. Root mean square deviation (RMSD) is employed to associate the change in concrete strength with changes in the PZT admittance signatures. The results show that the reusable setup is able to effectively monitor the initial hydration of concrete and the structural health. It can also be detached from the concrete for future re-use.
Method Pair Enumerator Clone Method Pairs Non-clone Method Pairs

Programmers produce code clones when developing software. By copying and pasting code with or without modification, developers reuse existing code to improve programming productivity. However, code clones present challenges to software maintenance: they may require consistent application of the same or similar bug fixes or program changes to multiple code locations. To simplify the maintenance process, various tools have been proposed to automatically detect clones [1], [2], [3], [4], [5], [6]. Some tools tokenize source code, and then compare the sequence or frequency of tokens to reveal clones [1], [3], [4], [5]. Some other tools detect clones using tree-matching algorithms to compare the Abstract Syntax Trees (ASTs) of source code [2], [6]. In this paper, we present CCLEARNER, the first solely token-based clone detection approach leveraging deep learning. CCLEARNER extracts tokens from known method-level code clones and nonclones to train a classifier, and then uses the classifier to detect clones in a given codebase. To evaluate CCLEARNER, we reused BigCloneBench [7], an existing large benchmark of real clones. We used part of the benchmark for training and the other part for testing, and observed that CCLEARNER effectively detected clones. With the same data set, we conducted the first systematic comparison experiment between CCLEARNER and three popular clone detection tools. Compared with the approaches not using deep learning, CCLEARNER achieved competitive clone detection effectiveness with low time cost. Keywords-deep learning; clone detection; empirical
Enhanced risk profiling of implanted defibrillator shocks with circulating SCN5A mRNA splicing variants: a pilot trial.

OBJECTIVES
The aim of this study was to determine the association of SCN5A cardiac sodium (Na(+)) channel mRNA splice variants in white blood cells (WBCs) with risk of arrhythmias in heart failure (HF).


BACKGROUND
HF is associated with upregulation of two cardiac SCN5A mRNA splice variants that encode prematurely truncated, nonfunctional Na(+) channels. Because circulating WBCs demonstrate similar SCN5A splicing patterns, we hypothesized that these WBC-derived splice variants might further stratify patients with HF who are at risk for arrhythmias.


METHODS
Simultaneously obtained myocardial core samples and WBCs were compared for SCN5A variants C (VC) and D (VD). Circulating variant levels were compared among patients with HF, divided into three groups: HF without an implantable cardioverter-defibrillator (ICD), HF with an ICD without appropriate intervention, and HF with an ICD with appropriate intervention.


RESULTS
Myocardial tissue-derived SCN5A variant expression levels strongly correlated with circulating WBC samples for both VC and VD variants (r = 0.78 and 0.75, respectively). After controlling for covariates, patients with HF who had received an appropriate ICD intervention had higher expression levels of both WBC-derived SCN5A variants compared with patients with HF with ICDs who had not received appropriate ICD intervention (odds ratio, 3.25; 95% CI, 1.64-6.45; p = 0.001). Receiver operating characteristic analysis revealed that circulating SCN5A variant levels were highly associated with the risk for appropriate ICD intervention (area under the curve ≥0.97).


CONCLUSIONS
Circulating expression levels of SCN5A variants were strongly associated with myocardial tissue levels. Furthermore, circulating variant levels were correlative with arrhythmic risk as measured by ICD events in an HF population within 1 year.

Preservice Teachers' Views of Inclusive Education: A Content Analysis.

Survey-based research was conducted with pre-service teachers, from a large regional Australian university, to explore their views about inclusion and their readiness to teach in inclusive classrooms. Open-ended questions were included in the survey to glean information on the respondents’ feelings and concerns about inclusion and inclusive practices. In addition, questions were framed to allow the respondents to discuss ways that the University could better prepare them as practising teachers. The responses to each of these questions were content analysed to delineate categories, and frequencies were calculated on the most salient categories. The results of this analysis are reported and comparisons are made of the views expressed by the respondents before they experience an inclusive education subject and a related practicum with those expressed after. The implications of the results for teacher education programs are considered.
Children's mental health and family functioning in Rhode Island.

OBJECTIVES
Our objectives were to (a) estimate the prevalence of children's mental health problems, (b) assess family functioning, and (c) investigate the relationship between children's mental health and family functioning in Rhode Island.


METHODS
From the 2003 National Survey of Children's Health, Rhode Island data for children 6 to 17 years of age were used for the analyses (N = 1326). Two aspects of family functioning measures, parental stress and parental involvement, were constructed and were examined by children's mental health problems, as well as other child and family characteristics (child's age, gender, race/ethnicity, special needs, parent's education, income, employment, family structure, number of children, and mother's general and mental health). Bivariate analyses and multivariate logistic regression were used to investigate the relationship.


RESULTS
Among Rhode Island children, nearly 1 (19.0%) in 5 had mental health problems, 1 (15.6%) in 6 lived with a highly stressed parent, and one third (32.7%) had parents with low involvement. Bivariate analyses showed that high parental stress and low parental involvement were higher among parents of children with mental health problems than parents of children without those problems (33.2% vs 11.0% and 41.0% vs 30.3%, respectively). In multivariate logistic regression, parents of children with mental health problems had nearly 4 times the odds of high stress compared with parents of children without those problems. When children's mental health problems were severe, the odds of high parental stress were elevated. However, children's mental health was not associated with parental involvement.


CONCLUSIONS
Children's mental health was strongly associated with parental stress, but it was not associated with parental involvement. The findings indicate that when examining the mental health issues of children, parental mental health and stress must be considered.
Brain oxygen metabolism may relate to the temperature gradient between the jugular vein and pulmonary artery after cardiopulmonary resuscitation.

OBJECTIVE
A gradient between the jugular vein temperature and core body temperature has been reported in animal and clinical studies; however, the pathophysiological meaning of this phenomenon remains unclear. This study was conducted to identify the temperature gradient between the jugular vein and pulmonary artery in comatose patients after cardiopulmonary resuscitation.


MATERIALS AND METHODS
The temperatures of the jugular vein and pulmonary artery were measured in 19 patients at 6 and 24 hours after cardiopulmonary resuscitation. Jugular venous blood saturation (SjO2; %) was also measured concomitantly. The patients were divided into 2 groups: high SjO2 (SjO2 > 75%: H-group; n = 10) and normal SjO2 (SjO2 < or = 75%: N-group; n = 9). The temperature gradient was calculated by subtracting the temperature of the pulmonary artery from that of the jugular vein (jugular - pulmonary = dT degrees C). Statistical significance was defined as p < 0.05.


RESULTS
dT was significantly lower in the H-group than in the N-group at 6 hours (0.120 +/- 0.011: mean +/- SD vs. 0.389 +/- 0.036: p = 0.0012) and 24 hours (0.090 +/- 0.005 vs. 0.256 +/- 0.030: p = 0.0136) after cardiopulmonary resuscitation.


CONCLUSION
The temperature gradient between the jugular vein and pulmonary artery was significantly lower in patients with high SjO2 after cardiopulmonary resuscitation. This temperature gradient may be reflected in brain oxygen metabolism.

Photo-inspired model-driven 3D object modeling

We introduce an algorithm for 3D object modeling where the user draws creative inspiration from an object captured in a single photograph. Our method leverages the rich source of photographs for creative 3D modeling. However, with only a photo as a guide, creating a 3D model from scratch is a daunting task. We support the modeling process by utilizing an available set of 3D candidate models. Specifically, the user creates a digital 3D model as a geometric variation from a 3D candidate. Our modeling technique consists of two major steps. The first step is a user-guided image-space object segmentation to reveal the structure of the photographed object. The core step is the second one, in which a 3D candidate is automatically deformed to fit the photographed target under the guidance of silhouette correspondence. The set of candidate models have been pre-analyzed to possess useful high-level structural information, which is heavily utilized in both steps to compensate for the ill-posedness of the analysis and modeling problems based only on content in a single image. Equally important, the structural information is preserved by the geometric variation so that the final product is coherent with its inherited structural information readily usable for subsequent model refinement or processing.
