It is shown that pairs of solitary pulses (SPs) in a linearly coupled system with opposite group velocity dispersions form robust breathing bound states. The system can be realized by temporal-modulation coupling of SPs with different carrier frequencies propagating in the same medium, or by coupling of SPs in a dual-core waveguide. Broad SP pairs are produced in a virtually exact form by means...

Measurements of transverse oscillations of single bunches of protons in the SPS at 26 GeV are described. They are used to monitor the transverse impedance of the SPS. There has been a major effort to reduce the SPS impedance in the last winter shutdown, by shielding of most pumping ports and removal of obsolete (lepton) components. In fact, a significant reduction in the coherent tune shift wit...

Synovial plica syndrome (SPS) occurs in the knee, when an otherwise normal structure becomes a source of pain due to injury or overuse. Patients may present to general practitioners, physiotherapists, or surgeons with anterior knee pain with or without mechanical symptoms, and the diagnosis can sometimes be difficult. Several studies have examined the epidemiology, diagnosis, and treatment of S...

Stiff-person syndrome (SPS) is a rare neurologic disease manifested by persistent muscle contractions causing marked rigidity in the affected individual . There are many case descriptions and clinical reviews in the neurologic literature, outlining a progression of knowledge from the early clinical description of SPS to advanced molecular biologic and immunologic studies implicating the gamma-a...

The session summarised here was devoted to Electron Cloud Effects and Vacuum in the SPS and LHC. Seven talks were presented, covering recent experimental observations of electron cloud effects at the KEK-B Low Energy Ring (LER), measurements of surface properties at EPA, simulations of electron cloud build-up and heat load, vacuum observations and electron scrubbing in the SPS with LHC type bea...

Stiff-person syndrome (SPS) is an autoimmune neurological disorder characterized by autoantibodies to glutamic acid decarboxylase (GAD), the enzyme responsible for the synthesis of inhibitory neurotransmitter GABA. To search for biomarkers that distinguish SPS from other neurological disorders (OND), we used surface enhanced laser desorption/ionization-time of flight (SELDI-TOF) mass spectromet...

Nitrogen (N) available to plants mostly originates from N(2) fixation carried out by prokaryotes. Certain cyanobacterial species contribute to this energetically expensive process related to carbon (C) metabolism. Several filamentous strains differentiate heterocysts, specialized N(2)-fixing cells. To understand how C and N metabolism are regulated in photodiazotrophically grown organisms, we i...

Stiff person syndrome (SPS) is a rare neurological disease with features of an autoimmune disease. SPS is characterised by severe progressive muscle stiffness of the spine and lower extremities with superimposed muscle spasms triggered by external stimuli such as noise, touch and emotional distress. Patients with SPS respond to high doses of muscle relaxants, such as diazepam and baclofen, seve...

Volumetric diameters Dv and specific surface area SpS of sludge particles formed during chemical coagulation and electrocoagulation of sewage were determined. The obtained aggregate-flocs differed substantially in both Dv and SpS values. The differences in Dv and SpS values of the analyzed particles were interpreted based on theoretical models for expanding aggregates. The most uniform particle...

Negative myoclonus (NM) is a motor disorder characterized by a sudden and abrupt interruption of muscular activity. The EMG correlate of NM is a brief (<500 ms) silent period (SP) not preceded by any enhancement of EMG activity (i.e. myoclonus). This study investigated the role of premotor cortex (PMC), primary motor cortex (MI), primary somatosensory area (SI) and supplementary motor area (SMA...
