On Complete Completion using Types and Weights

Viktor Kuncak, Tihomir Gvero, Ivan Kuraj, Ruzica Piskac

Developing modern software applications typically involves composing functionality from existing libraries. This task is difficult because libraries may expose many methods to the developer. To help developers in such scenarios, we present a technique that ...

Implementing a Type Debugger for Scala

Martin Odersky, Hubert Plociniczak

Statically-typed languages offer type systems that are less and less comprehensible for programmers as the language grows in complexity. In this paper, we present a type debugger, a tool that enables analysis of type-related problems as well as exploration ...

Relative Effect Declarations for Lightweight Effect-Polymorphism

Martin Odersky, Lukas Rytz

Type-and-effect systems are a well-studied approach for reasoning about the computational behavior of programs. A major roadblock in adopting effect systems in popular languages is the tradeoff between expressiveness and verbosity. In this technical report ...

Spatially and genetically distinct control of seed germination by phytochromes A and B

Christian Fankhauser

Phytochromes phyB and phyA mediate a remarkable developmental switch whereby, early upon seed imbibition, canopy light prevents phyB-dependent germination, whereas, later on, it stimulates phyA-dependent germination. Using a seed coat bedding assay where t ...

Capabilities for Uniqueness and Borrowing

Martin Odersky, Philipp Haller

An important application of unique object references is safe and efficient message passing in concurrent object-oriented programming. However, to prevent the ill effects of aliasing, practical systems often severely restrict the shape of messages passed by ...

The roles of mask luminance and perceptual grouping in visual backward masking

Michael Herzog, Gregory Francis

Visual backward masking is a commonly used technique in vision research and psychology. There are two distinct types of masking. Either masking is strongest for a simultaneous presentation of the target and the mask (A-type masking) or masking is strongest ...

Generics of a Higher Kind

Martin Odersky

With Java 5 and C-# 2.0, first-order parametric polymorphism was introduced in mainstream object-oriented programming languages under the name of generics. Although the first- order variant of generics is very useful, it also imposes some restrictions: it ...

Roving in perceptual learning: stimulus interference and overlapping neural populations

Michael Herzog, Elisa Tartaglia

Performance usually improves when observers train with one type of a visual stimulus. Roving denotes the situation when, instead of one, two or more types of stimuli are presented randomly interleaved (one per trial). For some stimulus types, performance i ...
