We consider transmission by a vector adder channel with two independent inputs and additive white Gaussian noise. Decisions on the channel output are made by individual decoders. A new metric for decoding in such a channel is proposed, which is a generalization of the correlation metric and is close to the optimal metric in some cases. Bounds on decoding error probability are given. A procedure fo

We studied electrophysiological properties of single chemosensory neurons in the mouthparts of the spiny lobsters Panulirus argus and Panulirus interruptus to complement our growing understanding of the behavioral roles of mouthparts of decapod crustaceans. Food mixtures and 13 single compounds were used to characterize the response specificity, sensitivity, and time course of individual neurons i

GRACILE-syndromet (Fellmans syndrom, MIM 603358) hör till det fi nländska genetiska sjukdomsarvet. Sjukdomen är orsakad av en missens mutation (S78G) i BCS1L, ett protein som fungerar som en “chaperon” eller sammankopplande länk vid bildning av komplex III i andningskedjan. Syndromet uttrycker sig som en grav tillväxthämning redan under fostertiden, och efter födseln utvecklar barnet en uttalad me

A reply to Thomas Roth, on the interpretation of photographs as historical sources.

A methodology for estimation of the unknown physical parameters in a detailed model for chromatographic processes is proposed. The model describes the concentration of the solute in the mobile phase and considers external/internal mass transfer resistance. The external volume and its mixing effect are also considered. The unknown model parameters estimated are the bed void, the axial dispersion co

alpha-Synuclein (alpha-Syn) accounts, as a major component of Lewy bodies (LB), for the filamentous deposits in many cases of neurodegenerative diseases. Yet, little is known about the molecular mechanisms of neuronal loss in these diseases. The correlation between alpha-Syn oligomerization/aggregation and pathologies raises the key question of which molecular form of alpha-Syn (i.e. monomeric alp

Elements of family dynamics have been shown to be related to onset, course, as well as prognosis of anorexia nervosa and bulimia nervosa. The goal was to explore the experience of family relations in a group of patients with eating disorders using a projective family test. The Patient group (anorexia=21, bulimia=16), as well as a healthy Control group, were given a projective family test, the Eati

This article reports on the successful stabilization of the carrier-envelope phase of a 1-kHz laser system that includes a large grating stretcher, a regenerative amplifier, a multipass amplifier and a grating compressor. Phase stability for pulse energies up to 6 mJ is demonstrated using electronic feedback to the oscillator locking electronics as well as feedback via an acousto-optic programmabl

A new method for collection of group data is described— Group Diary. Document studies in psychology are a background. Group members collect data as recorders and synthesize their notes. The method is a tool for learning, research and consultation. Methodological issues are elucidated. After presentation of five studies on group formation and development done by the authors, the pros and cons of th

1 The study was performed to clarify if apomorphine at the level of the rat corpus cavernosum can produce erectile responses or interfere with nerve-induced penile erection. 2 Apomorphine ( 10(-9) - 10(-4) M) exhibited a 10-fold higher potency to relax phenylephrine ( Phe)-than endothelin-1 ( ET-1)-induced contractions. Relaxant effects of apomorphine in Phe-activated corpus cavernosum did not cha

BACKGROUND: Orthostatic hypotension (OH) can be seen in as many as 30% to 50% of the elderly population as well as in dementia. OH is part of the autonomic dysfunction in dementia with Lewy bodies (DLB) and prevalent in the majority of these patients. It is also suggested to be a negative prognostic factor for survival in DLB. A detailed interpretation of the 10-minute orthostatic blood pressure m

The ATLAS detector as installed in its experimental cavern at point 1 at CERN is described in this paper. A brief overview of the expected performance of the detector when the Large Hadron Collider begins operation is also presented.

How to best measure working memory capacity is an issue of ongoing debate. Besides established complex span tasks, which combine short-term memory demands with generally unrelated secondary tasks, there exists a set of paradigms characterized by continuous and simultaneous updating of several items in working memory, such as the n-back, memory updating, or alpha span tasks. With a latent variable
