Cortical inhibitory neurons exhibit remarkable diversity in their morphology, connectivity, and synaptic properties. Here, we review the function of somatostatin-expressing (SOM) inhibitory interneurons, focusing largely on sensory cortex. SOM neurons also comprise a number of subpopulations that can be distinguished by their morphology, input and output connectivity, laminar location, firing p...

The paper presents a new method for adaptive selection of Self-Organizing Map (SOM) self-training endpoint. A method is based on the estimation of the newly introduced parameter ∆init and the learning depth parameter κ. In order to propose an optimal range of κ values, the influence of the selected learning depth parameter to the performance of SOM was tested experimentally using input data wit...

The temperature sensitivity of soil organic matter (SOM) decomposition has been a crucial topic in global change research, yet remains highly uncertain. One of the contributing factors to this uncertainty is the lack of understanding about the role of rhizosphere priming effect (RPE) in shaping the temperature sensitivity. Using a novel continuous C-labeling method, we investigated the temperat...

Rising temperatures in the Arctic can affect soil organic matter (SOM) decomposition directly and indirectly, by increasing plant primary production and thus the allocation of plant-derived organic compounds into the soil. Such compounds, for example root exudates or decaying fine roots, are easily available for microorganisms, and can alter the decomposition of older SOM ("priming effect"). We...

Den här uppsatsen behandlar ett antal individer begravda mellan 800 e.Kr. och 1150 e.Kr i ett tidigt kristet gravfält kring ruinen av Varnhems gårdskyrka. Av speciellt intresse är den placeringen som gravarna har i förhållande till kyrkomurarna och vad dessa placeringar innebär statusmässigt. Analys av stabila isotoper har därför utförts på de manliga individerna så att deras diet kan faställas...

The authors investigated the prevalence and characteristics of somatoform (SOM) disorders among 654 subjects with anxiety disorders who were part of the larger Harvard/Brown Anxiety Disorders Research Project. Thirty-six (5.5%) of the subjects had past or current SOM disorders. The subjects with SOM disorders were significantly more likely to have histories of posttraumatic stress disorder (22%...

In this paper, we describe the formatting guidelines for IJCA Journal Submission. The SOM, for kohonen Self Organizing Map, has proven to be a classifier of high caliber in the field of speech recognition signals breasts. Thus, several versions and enhancements were applied on this tool such as recurrent SOM 'RSOM', the growing recurrent SOM 'GRSOM' and the growing hierarchi...

Security is a major challenge for all distributed applications; however, it imposes additional concerns and requirements when Service-Oriented Computing (SOC) is used. Therefore, addressing the security issues is critical for the success of any SOC based project. Thus when utilizing service-oriented middleware (SOM), security could be included as part of the SOM architecture. SOM is a concept t...

Somatostatin (SOM) is an endogenous non-opioid neuropeptide that has analgesic effect in rodents and human beings. Previous studies indicated that SOM might be involved in the modulating effects of electroacupuncture (EA). Using immunohistochemistry and RT-PCR, the present study observed the effects of EA on the expression of SOM peptide and preprosomatostatin (ppSOM) mRNA in a rat model of neu...
