Distribution of kilohertz QPO frequencies and their ratios in the atoll source 4U 1636-53

A recently published study on long term evolution of the frequencies of the kilohertz quasi-periodic oscillations (QPOs) in the atoll source 4U 1636-53 concluded that there is no preferred frequency ratio in a distribution of twin QPOs that was inferred from the distribution of a single frequency alone. However, we find that the distribution of the ratio of actually observed pairs of kHz QPO frequencies is peaked close to the 3/2 value, and possibly also close to the 5/4 ratio. To resolve the apparent contradiction between the two studies, we examine in detail the frequency distributions of the lower kHz QPO and the upper kHz QPO detected in our data set. We demonstrate that for each of the two kHz QPOs (the lower or the upper), the frequency distribution in all detections of a QPO differs from the distribution of frequency of the same QPO in the subset of observations where both the kHz QPOs are detected. We conclude that detections of individual QPOs alone should not be used for calculation of the distribution of the frequency ratios.Comment: 6 pages, 4 figures, Acta Astronomica (accepted revised version

A survey of the European Reference Network EpiCARE on clinical practice for selected rare epilepsies

Objective: Clinical care of rare and complex epilepsies is challenging, because evidence-based treatment guidelines are scarce, the experience of many physicians is limited, and interdisciplinary treatment of comorbidities is required. The pathomechanisms of rare epilepsies are, however, increasingly understood, which potentially fosters novel targeted therapies. The objectives of our survey were to obtain an overview of the clinical practice in European tertiary epilepsy centers treating patients with 5 arbitrarily selected rare epilepsies and to get an estimate of potentially available patients for future studies. Methods: Members of the European Reference Network for rare and complex epilepsies (EpiCARE) were invited to participate in a web-based survey on clinical practice of patients with Dravet syndrome, tuberous sclerosis complex (TSC), autoimmune encephalitis, and progressive myoclonic epilepsies including Unverricht Lundborg and Unverricht-like diseases. A consensus-based questionnaire was generated for each disease. Results: Twenty-six of 30 invited epilepsy centers participated. Cohorts were present in most responding centers for TSC (87%), Dravet syndrome (85%), and autoimmune encephalitis (71%). Patients with TSC and Dravet syndrome represented the largest cohorts in these centers. The antiseizure drug treatments were rather consistent across the centers especially with regard to Dravet syndrome, infantile spasms in TSC, and Unverricht Lundborg / Unverricht-like disease. Available, widely used targeted therapies included everolimus in TSC and immunosuppressive therapies in autoimmune encephalitis. Screening for comorbidities was routinely done, but specific treatment protocols were lacking in most centers. Significance: The survey summarizes the current clinical practice for selected rare epilepsies in tertiary European epilepsy centers and demonstrates consistency as well as heterogeneity in the treatment, underscoring the need for controlled trials and recommendations. The survey also provides estimates for potential participants of clinical trials recruited via EpiCARE, emphasizing the great potential of Reference Networks for future studies to evaluate new targeted therapies and to identify novel biomarkers.info:eu-repo/semantics/publishedVersio

Relationship between amylose and zein content in maize and production performance of laying hens

Kukuruz je najzastupljenije krmivo u hranidbi peradi zbog čega razlike između hibrida mogu utjecati na proizvodne rezultate životinja. Cilj ovog istraživanja je bio istražiti razlike u sadržaju amiloze i zeina različitih hibrida kukuruza te kako te razlike utječu na proizvodna svojstva kokoši nesilica. Ukupno 90 Tetra nesilica je po tri bilo raspoređeno u kaveze koji su zatim prema kompletno nasumičnom planu dodijeljeni hranidbenim tretmanima. Hranidbeni tretmani su se razlikovali jedino u hibridu kukuruza (Bc 572, Kekec, Mejaš, Pajdaš i Riđan i jedan kontrolni). Tijekom proizvodnog pokusa koji je trajao 12 tjedana, pratila se nesivost, prosječni dnevni unos hrane, prosječna masa jaja, dnevna i tjedna jajna masa i konverzija, a na početku, sredini i kraju pokusa nesilice su vagane. Kemijske analize zrna su pokazale značajne razlike u sadržaju amiloze i zeina u ispitivanim hibridima kukuruza (P<0,0001). Utvrđeni prosječni sadržaj zeina je bio 60,94 g/kg ST (52,69–67,23 g/kg ST), a amiloze 191,33 g/kg ST (177,4 – 203,59 g/kg ST). Hibrid je značajno utjecao na sve proizvodne parametre (P<0,0001) osim nesivosti te je utvrđena povezanost sadržaja amiloze i zeina i proizvodnih pokazatelja nesilica. Negativna korelacija između sadržaja amiloze u ST i škrobu i prosječnog dnevnog unosa hrane (redom r=-0,132, P<0,05 i r=-0,180, P<0,01) upućuje da su nesilice hranjene hibridima s nižim sadržajem amiloze konzumirale manje hrane. Nesilice hranjene hibridima s višim omjerom amiloze i amilopektina konzumirale su manje hrane (r=-0,182, P<0,001) i imale bolju konverziju (r=-0,138, P<0,01), dok je viši sadržaj amilopektina bio povezan s višom prosječnom masom jaja (r=0,106, P<0,05). Sadržaj zeina u zrnu ispitivanih hibrida nije značajno utjecao na proizvodna svojstva.Since maize is the most commonly used feed in poultry, differences between hybrids could affect animal production performance. The aim of this study was to determine differences in the amylose and zein content in maize hybrids and how they affect production characteristics of laying hens. A total of 90 Tetra laying hens were randomly placed by three in cages which were allocated to dietary treatments in complete randomized plan. Treatments differentiated only in maize hybrid (Bc 572, Kekec, Mejaš, Pajdaš i Riđan and one control). During 12-week animal trial, egg production, average daily feed intake, average egg mass, daily and weekly egg mass and conversion were monitored, and hens were weighted at the beginning, in the middle and at the end of trial. Chemical analyses of grain showed significant differences in the contents of amylose and zein among tested hybrids (P<0.0001). The average zein content was 60.94 g/kg DM (52.69-67.23 g/kg DM) while for amylose was 191.33 g/kg DM (177.4-203.59 g/kg DM). All production parameters, except egg production, were affected by maize hybrid (P<0.0001), and relationship between hen production characteristics and contents of amylose and zein in maize were determined. Negative correlation between amylose content in DM and starch and average daily feed intake was observed (r=-0.132, P<0.05 and r=-0.180, P<0.01, respectively) implies that hens fed hybrids with lower amylose content consumed less. Hens fed hybrids with higher amylose/amylopectin ratio consumed less (r=-0.182, P<0.001) and had better feed conversion (r=-0.138, P<0.01). Hens fed hybrids with higher amylopectin content laid heavier eggs (r=0.106, P<0.05). Zein content of tested hybrids did not affect hens’ production characteristics

Best Analysis Selection in Inflectional Languages

Ambiguity is the fundamental property of natural language. Perhaps, the most burdensome case of ambiguity manifests itself on the syntactic level of analysis. In order to face up to the high number of obtained derivation trees, this paper describes several techniques for evaluation of the figures of merit, which define a sort order on parsing trees. The presented methods are based on language specific features of synthetical languages and they improve the results of simple stochastic approaches

Automatic Traffic Sign Detection and Recognition Using Colour Segmentation and Shape Identification

The paper describes a colour-based segmentation method of European traffic signs for detection in an image and a feature-based recognition method for categorizing them into given classes. At first, we have performed analysis of several well-known colour spaces as the RGB, HSV and YCbCr often used for segmentation purposes. The HSV colour space has been chosen as the most convenient for segmentation step and colour-based models of traffic signs representatives were created. Next, the fast radial symmetry (FRS) detection method and the Harris corner detector were used to recognize circles, triangles and squares as main geometrical shapes of the traffic signs. For these purposes a new gallery of real-life images containing traffic signs has been created and analysed. Overall efficiency of our recognition method is approx. 93 % on our gallery and is usable for real-time implementations
