Efficient generation of -photon generalized binomial states in a cavity
Extending a previous result on the generation of two-photon generalized
binomial field states, here we propose an efficient scheme to generate with
high-fidelity, in a single-mode high-Q cavity, N-photon generalized binomial
states with a maximum number of photons N>2. Besides their interest for
classical-quantum border investigations, we discuss the applicative usage of
these states in realizing universal quantum computation, describing in
particular a scheme that performs a controlled-NOT gate by dispersive
interaction with a control atom. We finally analyze the feasibility of the
proposed schemes, showing that they appear to be within the current
experimental capabilities.Comment: 8 pages, 2 figure
Las condiciones del trabajo doméstico remunerado en Argentina: la provisión de cuidados
This paper addresses the condition of domestic work in Argentina, in a perspective that draws from the literature on care work. In this approach, domestic work can be interpreted as one of the mercantile forms in which care work is socially organized, due to the persistence of the traditional sexual division of labor and the weakness of public policies. From these considerations, I develop a quantitative study on the levels of informality, precarity, and wage inequality that characterize domestic work in that country. Thereafter, I discuss the main measures adopted by the Argentine government since 2003, with the goal of reducing legal discrimination of domestic workers and promoting their formalization. On this basis, the paper highlights the advances in the recognition of domestic workers’ labor rights, while emphasizing how social and cultural restraints still permeate labor relations in this sector.Esta investigación aborda las condiciones del trabajo doméstico en Argentina, desde la perspectiva de la literatura sobre el cuidado. En este enfoque, el trabajo doméstico se interpreta como una de las formas mercantiles en las que se organiza socialmente el cuidado, frente a la persistencia de la tradicional división sexual del trabajo y ante la debilidad de las polÃticas públicas. A partir de estas consideraciones, se desarrolla un estudio cuantitativo de los niveles de informalidad, precariedad y desigualdad salarial que caracterizan al trabajo doméstico en ese paÃs. A continuación, se discuten las principales medidas adoptadas por los gobiernos argentinos a partir de 2003 con el objetivo de reducir la discriminación legal de las trabajadoras domésticas y promover su formalización. Sobre estas bases, el artÃculo evidencia los avances en el reconocimiento de los derechos laborales de las trabajadoras domésticas, a la vez qu
MICROVASCULAR CHARACTERISTICS OF THE HUMAN FILIFORM PAPILLAE:A VIDEOCAPILLAROSCOPIC STDY.
The aim of this study was to observe the microcirculation characteristics of the human
filiform papillae in healthy patients in vivo.
Twenty healthy patients were examined using lingual capillaroscopy to investigate
the characteristics of microcirculation of the human filiform papillae.
Visibility, course, tortuosity, as well as the possible presence of microhemorrhages,
the average caliber of the capillary loops and the number of visible capillary loops per
square millimeter were evaluated for each patient.
The investigation was simple, non-invasive and repeatable for each patient.
Microcirculation architecture was characterized by a network of capillaries in
polygonal mesh with parallel orientation in regard to the surface. Rare microhemorrhages
were observed. The caliber of visible capillary loops was 12.5071.46 mm
(mean7SD). The number of visible capillaries was 9.8871.06 (mean7SD).
Our study shows that capillaroscopy of lingual filiform papillae is a practicable
method. Future studies might evaluate whether microcirculation in that area is
compromised or not during systemic pathologies involving peripheral microcirculation
alterations. This method could also be applied to the study of microcirculation in
pathologies which strictly pertain to the dental stomatological field
Pain perception and stabilometric parameters in people with chronic low back pain after a pilates exercise program: A randomized controlled trial
Various exercise interventions, such as Pilates exercises and traditional physical therapy methods, are employed to decrease low back pain (LBP). Nonspecific low back pain (NSLBP) is distinct from LBP, however, as the distribution of pain is restricted to the region between the costal margin and the inferior gluteal. The aim of our randomized controlled trial was to evaluate the effects of a program of Pilates exercises on pain perception and stabilometric parameters in patients with NSLBP.Thirty-eight participants were randomly allocated, using a 1:1 scheme, to either the experimental group (EG) or control group (CG). The EG completed a 14-week program of Pilates exercises, performed thrice per week under the supervision of an exercise specialist, while the CG was managed with a social program only. Measures of posturography and Oswestry Disability Index (ODI) for pain perception were obtained at baseline (T0) and after the 14 weeks of intervention (T)1.Posturography measures improved for patients in the EG, with both eyes open and eyes closed (P\u200a<\u200a0.05). There were no statistical differences in posturography in the CG. ODI decreased significantly in both groups over the 14 weeks of the study protocol: EG, T0, 13.7\u200a\ub1\u200a5.0 compared with T1, 6.5\u200a\ub1\u200a4.0 (P\u200a<\u200a0.001); and CG, T0, 10.7\u200a\ub1\u200a7.8 compared with T1, 8.4\u200a\ub1\u200a7.8 (P\u200a<\u200a0.01). A greater extent of reduction in pain was achieved in the EG.The Pilates exercise program yielded improvements in pain and posturography outcomes. Our study also confirms the applicability of posturography in evaluating postural instability in patients with NSLBP. Due to our relatively small study group, future studies would be necessary to confirm our findings
Motor skill delays in pre-school children with leukemia one year after treatment: Hematopoietic stem cell transplantation therapy as an important risk factor
CNS-directed therapies for the treatment of leukemia can adversely affect the acquisition of new skills, such as reading/writing and math. Two years after the end of treatments, children show gross and fine motor skill delays that may persist even when patients are considered healed. The goal of the present study was to assess motor skills difficulties in pre-school children with leukemia one year after treatment. Particular attention has been paid to those patients who had undergone Hematopoietic Stem Cell Transplantation (HSCT) and to the relationship between motor delays and age bands.
Participants were 60 children (median age of 5; inter quartile range: 3.07-5.76), including 31 females and 29 males, 91.7% of them were affected by acute lymphoblastic leukemia (ALL), and 8.3% by acute myeloid leukemia (AML). Five children had undergone HCST. Parents were interviewed by Vineland Adaptive Behavior Scales (VABS) on children\u2019s motor skills and filled in the Italian Temperament Questionnaire (QUIT). VABS\u2019s total scores were converted into equivalent mental age scores (EMA). A score difference of at least three months between current age and equivalent mental age was considered a developmental delay. Non-parametric analyses were run to understand if HSCT treatment and a specific age band influence children\u2019s motor skills.
Significant delays were found in global motor skills (56.7%) as well as in fine and gross motor domains. Mann Whitney U tests showed that children with HSCT were reported to have lower gross motor mean ranks (U = 62; p=0.004; Mean rank =15.40) than peers without HSCT (Mean rank = 31.87) and lower mean rank values on motor temperament scale (U = 9; p = 0.003; HSCT Mean rank = 4.75 versus no HSCT Mean rank = 27.81). Kruskal Wallis\u2019 tests identified the high risk treatment showing that HSCT experience negatively impacted the motor skills and temperamental motor activity of pre-school children one year after the diagnosis of leukemia
Effects of protein supplementation in fitness world: A 12-week cross-over studio
The aim of this project was to evaluate the effect of isolated protein supplementation in young amateur athletes. Sixteen subjects aged between 20 and 30 were recruited for this study. Before to start sports performance was assessed at T0, in all subjects, using physical performance test and evaluated body composition. Therefore, the subjects were randomly assigned in two groups (group A and B) of 8 subjects each. The group A start to intake 30 g of protein powder diluted in water after each training session (3 times a week) for six weeks (T0) whilst the group B was the placebo. After 6 weeks (T1), the measurement were repeated for all subjects and the group A became placebo and the group B started with the supplementation. At the end of 6 weeks (T2) we carried out all the tests were performed again. Results showed a significant improvement in almost all tests between T0 and T2 within the same group (p < .05), but not significant difference was found between the start and the end of protein’s intake period in both groups. In conclusion, supplementation did not have affect the performance and body composition significantly. Instead, training seems to influence the performance more the supplementation

Resignificación del desempleo en la polÃtica social argentina frente al quiebre de la hegemonÃa neoliberal
Esta investigación aborda los cambios en las polÃticas estatales implementadas por Argentina en respuesta al problema del desempleo a lo largo de un periodo que abarca la década de los 90, de fuerte impronta neoliberal, la crisis de 2001-2002 y la etapa posterior del kirchnerismo. El análisis parte de la conceptualización del problema del desempleo y de la categorÃa de desocupado implÃcita en los documentos constitutivos de la polÃtica laboral (leyes, programas de empleo, etc.) a lo largo del periodo seleccionado, para indagar la persistencia de los rasgos neoliberales (y su cercanÃa a las corrientes económicas neoclásicas) o la emergencia (o recuperación) de paradigmas alternativos. En particular, se considera que el quiebre se juega entre la individualización de la situación del desocupado o una recuperación del concepto de desempleo como problema social colectivo
