Evolution and Revolution in Electronic packaging and Interconnection ; An Historical View of the Future

Bauer, Charles E. 한국마이크로전자및패키징학회 1997 Symposium on Multichip Module and Advanced Packagi Vol.1 No.1

Dramatic changes in the driving, forces of the electronics industry in the past twenty years have altered the rules in the world of packaging, interconnection and assembly. One of the most important changes is the shift from primarily government funded military and aerospace driven research and development to significant levels of corporate funded consumer driven R&D. Japan has been a leader in this arena far twenty years. Another major shift is occurring in the financial analysis of our industry, from cost focus to value focus. North America is the leader in this area. The third important topic consdered in this paper is the demand for a packaging discipline that incorporates the first two topics, particularly within an educational environment. Advances in this area were initiated in North America, but Europe has begun to take the lead here. This paper and presentation describes the evolution of these major paradigm shifts in the industry and explores the implications for participants in the packaging, interconnection and assembly industry, whether suppliers of materials, equipment and processes or . designer's, fabricators and assemblers of products. Revolutionary changes in the balance between original equipment manufacturers and contract fabricators and assemblers, distributors and component suppliers, and designers and their systems are occurring and will be demanded by these paradigm shifts. The reasons and forces behind these expectations are presented along with a road map to the future of the electronic packaging, interconnection and assembly industry!

Commuting Toeplitz operators with quasi-homogeneous symbols on the Segal-Bargmann space

Bauer, W.,Issa, H. Academic Press 2012 Journal of mathematical analysis and applications Vol.386 No.1

Let T=T<SUB>z^lz@?^k</SUB> with l,k@?N<SUB>0</SUB> be a Toeplitz operator with monomial symbol acting on the Segal-Bargmann space over the complex plane. We determine the symbols Ψ of polynomial growth at infinity such that T<SUB>Ψ</SUB> and T<SUB>z^lz@?^k</SUB> commute on the space of all holomorphic polynomials. By using polar coordinates we represent Ψ as an infinite sum Ψ(re<SUP>iθ</SUP>)=@?<SUB>j=-~</SUB><SUP>~</SUP>Ψ<SUB>j</SUB>(r)e<SUP>ijθ</SUP>. Then we are able to reduce the above problem to the case of quasi-homogeneous symbols Ψ=Ψ<SUB>j</SUB>e<SUP>ijθ</SUP>. We obtain the radial part Ψ<SUB>j</SUB>(r) in terms of the inverse Mellin transform of an expression which is a product of Gamma functions and a trigonometric polynomial. If we allow operator symbols of higher growth at infinity, we point out that in some of the cases more than one Toeplitz operator T<SUB>Ψ'je^i^j^θ</SUB> exists commuting with T.

Can Perioperative Chemotherapy for Advanced Gastric Cancer Be Recommended on the Basis of Current Research? A Critical Analysis

Bauer, Katrin,Porzsolt, Franz,Henne-Bruns, Doris The Korean Gastric Cancer Association 2014 Journal of gastric cancer Vol.14 No.1

Purpose: According to current guidelines, perioperative chemotherapy is an integral part of the treatment strategy for advanced gastric cancer. Randomized controlled studies have been conducted in order to determine whether perioperative chemotherapy leads to improved R0 resection rates, fewer recurrences, and prolonged survival. The aim of our project was to critically appraise three major studies to establish whether perioperative chemotherapy for advanced, potentially resectable gastric cancer can be recommended on the basis of their findings. Materials and Methods: We analyzed the validity of the three most important studies (MAGIC, ACCORD, and EORTC) using a standardized questionnaire. Each study was evaluated for the study design, patient selection, randomization, changes in protocol, participating clinics, preoperative staging, chemotherapy, homogeneity of subjects, surgical quality, analysis of the results, and recruitment period. Results: All three studies had serious shortcomings with respect to patient selection, homogeneity of subjects, changes in protocol, surgical quality, and analysis of the results. The protocols of the MAGIC and ACCORD-studies were changed during the study period because of insufficient recruitment, such that carcinomas of the lower esophagus and the stomach were examined collectively. In neither the MAGIC study nor the ACCORD study did patients undergo adequate lymphadenectomy, and only about half of the patients in the chemotherapy group could undergo the treatment specified in the protocol. The EORTC study had insufficient statistical power. Conclusions: We concluded that none of the three studies was sufficiently robust to justify an unrestrained recommendation for perioperative chemotherapy in cases of advanced gastric cancer.

Efficient Exact Inference With Loss Augmented Objective in Structured Learning

Bauer, Alexander,Nakajima, Shinichi,Muller, Klaus-Robert IEEE 2017 IEEE transactions on neural networks and learning Vol.28 No.11

<P>Structural support vector machine (SVM) is an elegant approach for building complex and accurate models with structured outputs. However, its applicability relies on the availability of efficient inference algorithms-the state-of-the-art training algorithms repeatedly perform inference to compute a subgradient or to find the most violating configuration. In this paper, we propose an exact inference algorithm for maximizing nondecomposable objectives due to special type of a high-order potential having a decomposable internal structure. As an important application, our method covers the loss augmented inference, which enables the slack and margin scaling formulations of structural SVM with a variety of dissimilarity measures, e.g., Hamming loss, precision and recall, F-beta-loss, intersection over union, and many other functions that can be efficiently computed from the contingency table. We demonstrate the advantages of our approach in natural language parsing and sequence segmentation applications.</P>

Accurate Maximum-Margin Training for Parsing With Context-Free Grammars

Bauer, Alexander,Braun, Mikio,Muller, Klaus-Robert IEEE 2017 IEEE transactions on neural networks and learning Vol.28 No.1

<P>The task of natural language parsing can naturally be embedded in the maximum-margin framework for structured output prediction using an appropriate joint feature map and a suitable structured loss function. While there are efficient learning algorithms based on the cutting-plane method for optimizing the resulting quadratic objective with potentially exponential number of linear constraints, their efficiency crucially depends on the inference algorithms used to infer the most violated constraint in a current iteration. In this paper, we derive an extension of the well-known Cocke-Kasami-Younger (CKY) algorithm used for parsing with probabilistic context-free grammars for the case of loss-augmented inference enabling an effective training in the cutting-plane approach. The resulting algorithm is guaranteed to find an optimal solution in polynomial time exceeding the running time of the CKY algorithm by a term, which only depends on the number of possible loss values. In order to demonstrate the feasibility of the presented algorithm, we perform a set of experiments for parsing English sentences.</P>

Comparison of International Guidelines on the Accompanying Therapy for Advanced Gastric Cancer: Reasons for the Differences

Bauer, Katrin,Schroeder, Marcel,Porzsolt, Franz,Henne-Bruns, Doris The Korean Gastric Cancer Association 2015 Journal of gastric cancer Vol.15 No.1

The purpose of this study was to determine if international guidelines differ in their recommendations concerning additive therapy for advanced, but potentially curable, gastric cancer. A systematic search of the English and German literature was conducted in the databases Medline, Cochrane Database, Embase, and PubMed. The search terms used were 'guidelines gastric cancer,' 'guidelines stomach cancer,' and 'Leitlinien Magenkarzinom.' Six different guidelines published after January 1, 2010, in which the tumors were classified according to the seventh edition of the TNM system (2010), were identified. Although the examined guidelines were based on the same study results, their recommendations concerning accompanying therapy for gastric cancer differ considerably. While perioperative chemotherapy is recommended in Germany, Great Britain, and large parts of Europe, postoperative adjuvant radiochemotherapy or perioperative chemotherapy is recommended in the USA and Canada. In Japan, postoperative adjuvant chemotherapy is recommended. The results of identical studies were interpreted differently in different countries. Since considerable effort is required for each country to separately test relevant studies for their validity and suitability, an international cooperation could simplify the creation of a common basis for guidelines and contribute to improved comparability of international guidelines.
