Single observable concurrence measurement without simultaneous copies

We present a protocol that allows us to obtain the concurrence of any two qubit pure state by performing a minimal and optimal tomography of one of the subsystems through measuring a single observable of an ancillary four dimensional qudit. An implementation for a system of trapped ions is also proposed, which can be achieved with present day experimental techniques.Comment: 4 pages, 1 figur

Specific plasmid patterns and high rates of bacterial co-occurrence within the coral holobiont

Despite the importance of coral microbiomes for holobiont persistence, the interactions among these arenot well understood. In particular, knowledge of the co-occurrence and taxonomic importance of specific members of the microbial core, as well as patterns of specific mobile genetic elements (MGEs), is lacking. We used seawater and mucus samples collected from Mussismilia hispida colonies on two reefs located in Bahia, Brazil, to disentangle their associated bacterial communities, intertaxa correlations, and plasmid patterns. Proxies for two broad-host-range (BHR) plasmid groups, IncP-1 and PromA, were screened. Both groups were significantly (up to 252 and 100%, respectively) more abundant in coral mucus than in seawater. Notably, the PromA plasmid group was detected only in coral mucus samples. The core bacteriome of M.hispidamucus was composed primarily of members of the Proteobacteria, followed by those of Firmicutes. Significant host specificity and co-occurrences among different groups of the dominant phyla (e.g., Bacillaceae and Pseudoalteromonadaceae and the genera Pseudomonas, Bacillus, and Vibrio) were detected. These relationships were observed for both the most abundant phyla and the bacteriome core, in which most of the operational taxonomic units showed intertaxa correlations. The observed evidence of host-specific bacteriome and co-occurrence (and potential symbioses or niche space co-dominance) among the most dominant members indicates a taxonomic selection of members of the stable bacterial community. In parallel, host-specific plasmid patterns could also be, independently, related to the assembly of members of the coral microbiome

Biodegradação do bagaço de cana-de-açúcar por microrganismos ruminais de caprinos e ovinos.

Resumo: No presente estudo objetivou-se avaliar a degradação do bagaço de cana-de-açúcar (BCA) integral (BIN) ou hidrolisado (BH) pela microbiota ruminal de caprinos e ovinos de raças naturalizadas do Nordeste brasileiro e o potencial desses animais como fontes de microrganismos e/ou enzimas celulolíticas para degradação da fibra do BCA. Para hidrólise do BCA foi utilizada uma solução de NaOH a 50%, 30% na matéria seca (MS). Foram determinadas as concentrações de MS, proteína bruta (PB), cinzas (CZ), fibra detergente neutro (FDN), fibra detergente ácido (FDA), celulose (Cel), hemicelulose (Hcel) e lignina (Lig). A degradação in situ da FDN foi determinada pela incubação ruminal em sacos de náilon do BH nos tempos: 0, 6, 24 e 96 horas. A técnica de duas etapas preconizada por Tilley e Terry foi utilizada para determinar a digestibilidade in vitro da MS (DIVMS). Foi coletado conteúdo ruminal dos animais quatro horas após a infusão de 100g de BIN via fístula ruminal para a separação de microrganismos associados às fases líquida e sólida, utilizando tampão fosfato de sódio 50 mM, pH 6,9. A fração sólida foi submetida ao cultivo in vitro com o substrato BIN, por 96 horas, para determinação da taxa de degradação da MS, FDN e atividade celulolítica. O pH foi determinado nos tempos de cultivo de 24, 48 e 96 horas. O pré-tratamento com NaOH aumentou a DIVMS (P0,05). A inclusão de NaOH aumentou a degradação in situ da FDN, apresentando os ovinos menor tempo de colonização (TC). Houve solubilização da Hcel, da Cel e da Lign no BCA pré-tratado com NaOH. A atividade celulolítica se concentrou na fração sólida independente da espécie doadora do inóculo, sendo observado crescimento microbiano no cultivo in vitro do BIN à partir dessa fração. O pH aumentou com o tempo de cultivo in vitro. Microrganismos ruminais de Caprinos e ovinos naturalizados do Nordeste brasileiro colonizaram e degradaram o BIN e BH. O NaOH pode ser utilizado no pré-tratamento alcalino do BCA. [Biodegradation of sugarcane bagasse by ruminal microorganisms from sheep and goats]. Abstract: The purpose of this study was to evaluate the biodegradation of sugar cane bagasse (SCB), whole (WB) or hydrolyzed (HB) by ruminal microorganisms from Brazilian naturalized goat and sheep breeds, and the animals? potential as a source of microorganisms and/or cellulolytic enzymes for the biodegradation of SCB fiber. SCB hydrolysis was performed using 50% sodium hydroxide solution on 30% of dry matter (DM). The concentrations of DM, crude protein (CP), ether extract (EE), ash, neutral detergent fiber (NDF), acid detergent fiber (ADF), cellulose (Cel), hemicellulose (Hcel) and lignin (Lig) were determined in the WB and HB. For the in situ biodegradation of NDF, the HB was placed in nylon bags and incubated in rumen for 0, 6, 24 and 96 hours. The two-step technique recommended by Tilley and Terry was used to determine the in vitro digestibility of DM (IVDDM). Four hours after infusion of WB (100 g) through the ruminal fistula, the rumen content was collected from the animals and the microorganisms associated with the liquid and solid phases were separated, the former by filtration and the latter by extraction with 50 mM sodium phosphate buffer, pH 6.9. The solid fraction was subjected to in vitro culture with WB substrate for 96 hours to determine the biodegradation rate of DM, NDF and cellulolytic activity. The pH was measured after culture times of 24, 48 and 96 hours. Pretreatment with NaOH increased the IVDDM (P 0.05). The addition of NaOH increased the in situ biodegradation rate of NDF, with sheep showing a lower lag time (LT). There was a solubilization of Hcel, Cel and Lig in SCB pretreated with NaOH. Cellulolytic activity was higher in the solid phase, irrespective of the inoculum source, and microbial growth was observed in in vitro cultures using microorganisms from the solid phase and WB as substrate. The pH of the in vitro culture increased over time. Ruminal microorganisms from Brazilian naturalized goat and sheep breeds successfully colonized and biodegraded both WB and HB. Sodium hydroxide proved useful as an alkaline pretreatment for SCB

Degradabilidade in situ do bagaço de cana-de-açúcar para pequenos ruminantes de raças naturalizadas do Nordeste brasileiro.

Resumo: Com o crescimento da indústria sucroalcooleira, buscam-se alternativas de uso dos resíduos gerados por ela. Os pequenos ruminantes de raças naturalizadas do Nordeste brasileiro mostram-se como grupos potenciais para que seja utilizado o bagaço de cana-de-açúcar (BCA) nas dietas. Nesse contexto, objetivou-se determinar a degradabilidade ruminal in situ da matéria seca (MS) e da fibra em detergente neutro (FDN) do BCA e os parâmetros ruminais em caprinos Moxotó e ovinos Morada Nova, fistulados no rúmen. Contidos em sacos de náilon, 3g de BCA foram incubados no rúmen nos tempos seis, 24 e 96 horas, determinando-se o conteúdo de MS e FDN nos resíduos obtidos. Nos tempos zero, seis e 12 horas após a primeira refeição, mediram-se no líquido ruminal pH e nitrogênio amoniacal (N-NH3) ruminal. O CMS não diferiu entre caprinos e ovinos. O potencial de máxima degradação da MS foi semelhante entre espécies, e da FDN foi superior em caprinos. Ovinos apresentaram maiores tempo de colonização, taxa de degradação e degradabilidade efetiva da MS e FDN. O pH não diferiu entre as espécies. Observou-se maior concentração de N-NH3 ruminal em caprinos, no tempo zero. Diante da maior velocidade de degradação da MS do BCA pelos ovinos, essa espécie se mostra detentora de uma microbiota ruminal com crescimento mais eficiente sobre o BCA. [In situ degradability of sugarcane bagasse for naturalized small ruminant breeds from the northeastern Brazil]. Abstract: With the increase of the sugar and alcohol industries, alternative uses for residue are sought, and the small ruminants from the naturalized breeds of northeastern Brazil are potential groups to make use of the sugarcane bagasse (SCB) in their diets. In this context, the objective was to determine the in situ degradability of dry matter (DM) and neutral detergent fiber (NDF) of SCB and ruminal parameters in Moxotó goats and Morada Nova sheep rumen fistulated. Three grams of SCB were placed in naylon bags and incubated in the rumen at 6, 24 and 96 hours, and the residues analyzed for DM and NDF. Rumen fluid was collected at zero, 6 and 12 hours after the first meal and pH and ammonia nitrogen (N-NH3) were determined. DMI did not differ between goats and sheep. The maximum degradation potential of DM was similar between species and the A of NDF was higher in goats. Sheep had higher colonization time, rate of degradation and effective degradability of DM and NDF. The pH did not differ between species. The highest concentration of ruminal N-NH3 in goats was at time zero. Given the higher rate of degradation of bagasse dry matter by sheep, this specie shows a more efficient rumen microbial growth on SCB

Comparison of reduction methods for finite element geometrically nonlinear beam structures

The aim of this contribution is to present numerical comparisons of model-order reduction methods for geometrically nonlinear structures in the general framework of finite element (FE) procedures. Three different methods are compared: the implicit condensation and expansion (ICE), the quadratic manifold computed from modal derivatives (MD), and the direct normal form (DNF) procedure, the latter expressing the reduced dynamics in an invariant-based span of the phase space. The methods are first presented in order to underline their common points and differences, highlighting in particular that ICE and MD use reduction subspaces that are not invariant. A simple analytical example is then used in order to analyze how the different treatments of quadratic nonlinearities by the three methods can affect the predictions. Finally, three beam examples are used to emphasize the ability of the methods to handle curvature (on a curved beam), 1:1 internal resonance (on a clamped-clamped beam with two polarizations), and inertia nonlinearity (on a cantilever beam)

The safety and clinical effectiveness of rapid infusion with CT-P10 in patients with non-Hodgkin's lymphoma or chronic lymphocytic leukemia: A retrospective non-interventional post-authorization safety study in Europe

Rapid infusion (RI) of the rituximab biosimilar CT-P10 is currently only an approved treatment regimen for the treatment of rheumatoid arthritis. Although both CT-P10 and reference rituximab are known to be frequently administered using a RI regimen (≤90 min) in clinical practice, published data on the safety of RI of CT-P10 in patients with NHL and CLL are limited. Hence, this study collected real-world safety and effectiveness data on RI-CT-P10 from the medical records of 196 patients with NHL or CLL in 10 European centers, 6 months after the date of the first RI (index date); the infusion-related reaction (IRR) rate was compared to previously published data. Ten percent (95% confidence interval 6%–15%; n = 20/196) of patients experienced an infusion-related reaction (IRR) on day 1–2 post-index, which was not significantly different (p = 0.45) to the IRR rate for rituximab described in a previous meta-analysis (8.8%). During the observation period, 2% of patients experienced grade 3–5 IRRs and 85% (n = 166) experienced an adverse event (non-IRR). The most common reason for discontinuation of first-line CT-P10 was planned treatment completion (81%; n = 158). Complete response and partial response to CT-P10 was observed in 74% (n = 142/192) and 22% (n = 42/192) of patients, respectively. The results of this real-world study demonstrate that the safety and effectiveness profile of RI-CT-P10 is similar to RI of reference rituximab and therefore support the current use of RI-CT-P10 in patients with NHL and CLL
