Critical Resistance

Abstract A single cell failure (SCF) is a common fail signature in dynamic random access memories (DRAMs). Generally write and read problems can be observed if a cell capacitor is not connected properly to its bitline. If the critical resistance of this connection exceeds a given threshold a failure might occur. In this analysis this threshold can be varied by a lateral gate effect of neighboring trenches. The first section gives a short introduction to the problem. An experimental analysis follows in the second section. Simulation results are presented in the third part and a short summary is given at the end.

Abstract A common failure signature in dynamic random access memories (DRAMs) is the single cell failure. The charge is lost and thereby the information stored in trench capacitors can be destroyed by high resistive leakage paths. The nature of the leakage path determines the properties of the failure such as temperature-, voltage- and timing-dependencies and its stability. In this study, high resistive leakage paths were investigated and delimited from classical shorts by estimating the order of magnitude of the leakage current and by comparison to a simple resistive leakage path. Such an investigation is the basis for a defect-based test approach that leads to multiparameter tests [1]. An introduction to the problem is given in the first section, while the second section deals with the characterization of the defects in two case studies. A short summary is given in the end.

Short Summary

The article consists of four parts. The first is a short introduction to tenant influence in Sweden. In the second part certain motives and aims for tenant influence are deduced. Some conflicts of aims and some consequences of how this influence is organized are pointed at. The third part presents a short summary of an evaluation of an experiment with tenant influence. The conclusion is that the formal right to decide on certain questions, delegated to the tenants, did not lead to any genuine influence. Finally, a tendency toward professionalization of the neighbourhood committees and its consequences are discussed.

The growing attention toward the benefits of single-cell RNA sequencing (scRNA-seq) is leading to a myriad of computational packages for the analysis of different aspects of scRNA-seq data. For researchers without advanced programing skills, it is very challenging to combine several packages in order to perform the desired analysis in a simple and reproducible way. Here we present DIscBIO, an open-source, multi-algorithmic pipeline for easy, efficient and reproducible analysis of cellular sub-populations at the transcriptomic level. The pipeline integrates multiple scRNA-seq packages and allows biomarker discovery with decision trees and gene enrichment analysis in a network context using single-cell sequencing read counts through clustering and differential analysis. DIscBIO is freely available as an R package. It can be run either in command-line mode or through a user-friendly computational pipeline using Jupyter notebooks. We showcase all pipeline features using two scRNA-seq datasets. The first dataset consists of circulating tumor cells from patients with breast cancer. The second one is a cell cycle regulation dataset in myxoid liposarcoma. All analyses are available as notebooks that integrate in a sequential narrative R code with explanatory text and output data and images. R users can use the notebooks to understand the different steps of the pipeline and will guide them to explore their scRNA-seq data. We also provide a cloud version using Binder that allows the execution of the pipeline without the need of downloading R, Jupyter or any of the packages used by the pipeline. The cloud version can serve as a tutorial for training purposes, especially for those that are not R users or have limited programing skills. However, in order to do meaningful scRNA-seq analyses, all users will need to understand the implemented methods and their possible options and limitations.

AbstractWe present a Minimal Event Distance Aneuploidy Lineage Tree (MEDALT) algorithm that infers the evolution history of a cell population based on single-cell copy number (SCCN) profiles, and a statistical routine named lineage speciation analysis (LSA), whichty facilitates discovery of fitness-associated alterations and genes from SCCN lineage trees. MEDALT appears more accurate than phylogenetics approaches in reconstructing copy number lineage. From data from 20 triple-negative breast cancer patients, our approaches effectively prioritize genes that are essential for breast cancer cell fitness and predict patient survival, including those implicating convergent evolution.The source code of our study is available at https://github.com/KChen-lab/MEDALT.

Short Summary

The paper presents an interpretation of Brandom’s analysis of de re specifying attitude-ascriptions. According to this interpretation, his analysis amounts to a deflationist conception of intentionality. In the first section I sketch the specific role deflationist theories of truth play within the philosophical debate on truth. Then I describe some analogies between the contemporary constellation of competing truth theories and the current confrontation of controversial theories of intentionality. The second section gives a short summary of Brandom’s analysis of attitude-ascription, focusing on his account of the grammar of de re ascriptions of belief. The third section discusses in detail those aspects of his account from which a deflationist conception of intentionality may be derived, or which at least permit such a conception. In the proposed interpretation of Brandom’s analysis, the vocabulary expressing the representational directedness of thought and talk does not describe a genuine property of mental states, but has an alternative descriptive function and in addition contains a performative and a meta­descriptive element.

Short Time

On May 11, 1938, two New Orleans policemen entered the Astoria Restaurant, marched to the kitchen, and approached Loyd D. T. Washington, a 41-year-old African American cook. They informed Washington that they would be taking him to the First Precinct station for questioning, although they assured the cook that he need not change his clothes and “should be right back” to the “Negro restaurant,” where he had worked for 3 years. Immediately after arriving at the station house, police officers “surrounded” Washington, showed him a photograph of a man, and announced that he had killed a white man in Yazoo City, Mississippi, 20 years earlier. When Washington insisted that he did not know the man in the photograph, that he had never been to (or even heard of) Yazoo City, and that he had been in the army at the time of the murder, the law enforcers confined him in a cell, although they had no warrant for his arrest and did not charge him with any crime. The following day, a detective brought him to the “show-up room” in the precinct house, where he continued the interrogation and, according to Washington, “tried to make me sign papers stating that I had killed a white man” in Mississippi. As every African American New Orleanian knew, the show-up (or line-up) room was the setting where detectives tortured suspects and extracted confessions. “You know you killed him, Nigger,” the detective roared. Washington, however, refused to confess, and the detective began punching him in the face, knocking out five of his teeth. After Washington crumbled to the floor, the detective repeatedly kicked him and broke one of his ribs. The beating continued for an hour, until other policemen restrained the detective, saying “give him a chance to confess and if he doesn't you may start again.” But Washington did not confess, and the violent interrogation began anew. A short time later, another police officer interrupted the detective, telling him “do not kill this man in here, after all he is wanted in Yazoo City.” Bloodied and writhing in pain, Washington asked to contact his family, but the request was ignored. Because he had not been formally charged with a crime, New Orleans law enforcers believed that Washington had no constitutional protection again self-incrimination or coercive interrogation and no right to an arraignment or bail, and they had no obligation to contact his relatives or to provide medical care for him.

First Time

There are many still unstudied aspects of the cultural history of early Quattrocento Rome, especially if we consider the years before 1443, the date of the more or less permanent re-entry into the civitas aeterna of Pope Eugenius IV. The nexus between the still ephemeral papacy and the emerging intellectual movement of Italian Renaissance humanism is one of these aspects. It is hoped that this study will shed some light on this problem by presenting a document that has hitherto not been completely edited: the original will of Cardinal Giordano Orsini. As we shall see, this important witness to the fifteenth century provides valuable information on many fronts, even on the structure of the old basilica of Saint Peter. The short introduction is in three parts. The first has a discussion of the cardinal's cultural milieu with a focus on the only contemporary treatise specifically about curial culture, Lapo da Castiglionchio's De curiae commodis. The second part addresses the textual history of the will as well as some misconceptions which have surrounded it. The third part contains a discussion of the will itself, along with some preliminary observations about what can be learned from the critical edition of the text here presented for the first time.
