Intermediate coherent-phase(PB) states of radiation fields and their nonclassical properties

Intermediate states interpolating coherent states and Pegg-Barnett phase states are investigated using the ladder operator approach. These states reduce to coherent and Pegg-Barnett phase states in two different limits. Statistical and squeezing properties are studied in detail.Comment: 9 pages, 3 EPS figures, use epsf.sty.

Comparação de características demográficas e clínicas entre crianças e adolescentes com transtorno depressivo maior

OBJECTIVE: To compare clinical characteristics of major depressive disorder symptoms between children and adolescents. METHOD: The subjects were 58 patients of a Child and Adolescent Affective Disorder Clinic consecutively admitted during a six-month period. Children aged 5-9 years old and adolescents from 10-17 years old currently meeting DSM-IV criteria diagnosis of major depressive disorder were chosen. Current MDD diagnosis and depressive psychopathology were assessed by a clinical interview and the Diagnostic Interview for Children and Adolescents-DSM-IV version. The Children’s Depression Rating Scale-Revised Version and the Children Global Assessment Scale rated the severity and global functioning of major depressive disorder. RESULTS: The most common depressive symptoms were: anhedonia (72.4%), depressed mood (72.4%), decreased concentration (62.1%), and irritability (58.6%). The intensity of depressive episodes of this sample ranged from mild to moderate. Fifty percent reported thoughts of death, and 29.3% presented a variety of psychotic symptoms. When compared with children, adolescents reported a significantly more depressed mood (p = 0.043), lower self-esteem (p = 0.002), and had more difficulty concentrating (p = 0.020). Female adolescents had lower self-esteem (p = 0.003), and male adolescents showed more decreased concentration (p = 0.016). CONCLUSION: This study suggests that age and gender differences might influence the clinical presentation of major depressive disorder in children and adolescents. Further studies with larger samples are needed.OBJETIVO: Comparar as características clínicas de transtorno depressivo maior entre crianças e adolescentes. MÉTODO: Amostra constituída de 58 sujeitos admitidos consecutivamente em um serviço especializado em transtornos do humor na infância e adolescência durante um período de 6 meses. Foram considerados crianças sujeitos com idade entre 5 e 9 anos, e adolescentes aqueles com idade entre 10 e 17 anos. Todos os participantes preenchiam diagnóstico de transtorno depressivo maior seguindo os critérios de DSM-IV. O diagnóstico de transtorno depressivo maior e avaliação de aspectos psicopatológicos foram realizados por entrevista clínica direta e aplicação de entrevista de apoio ao diagnóstico. O funcionamento global e a gravidade dos sintomas depressivos foram mensurados através de versões adaptadas de Children’s Depression Rating Scale-Revised Version e Children Global Assessment Scale. RESULTADOS: Os sintomas depressivos mais freqüentes foram: anedonia (72,4%), humor depressivo (72,4%), diminuição de concentração (62,1%) e irritabilidade (58,6%). A intensidade do episódio depressivo dessa amostra variou de leve a moderada. Cinqüenta por cento relataram pensamentos mórbidos e 29,3% apresentaram sintomas psicóticos variados. Quando comparados com crianças, adolescentes apresentaram significativamente mais humor depressivo (p = 0,043), baixa auto-estima (p = 0,002) e mais dificuldade de concentração (p = 0,020). As adolescentes femininas tinham mais baixa auto-estima (p = 0,003) e os masculinos mostraram mais diminuição de concentração (p = 0,016). CONCLUSÃO: Esse estudo sugere que idade e gênero poderiam influenciar na apresentação clínica de transtorno depressivo maior em crianças e adolescentes. Estudos com amostra mais representativa serão necessários

Thought and language disorders in very early onset schizophrenia, schizoaffective disorder and bipolar disorder

Background: Thought and language disorders are main features of adults with schizophrenia and bipolar disorders however studies on such abnormalities are scant in young patients with very early onset psychosis (VEOS). The aim of the present study is to assess the relationship between language and thought disorders in patients with very early onset schizophrenia (SCZ), schizoaffective disorders (SCA) and bipolar disorders (BD). Method: Forty-one patients (18 SCZ, 16 BD, and 7 SCA) with mean age less than 15 years old were assessed through a series of neurocognitive and psycholinguistic tests, including the Thought, Language and Communication Scale (TLC). Results: SCZ group performed worse in all tests as well as the TLC, followed by SCA and BD groups respectively. Thought disorders were related to deficits in executive functioning and semantic processing, and the metaphors' test was the best predictor of TLC functioning. Discussion: TD in SCZ, SCA and BD are one of the most important features in patients with VEOS and that the evaluation of metaphor comprehension can be an important instrument in the early detection of this disorder.Univ Sao Paulo, Sch Med FMUSP, Dept & Inst Psychiat, Sao Paulo, SP, BrazilUniv Fed Sao Paulo Unifesp, Sao Jose Dos Campos, SP, BrazilUniv Fed Sao Paulo Unifesp, Sao Jose Dos Campos, SP, BrazilWeb of Scienc

Carcinoma ex pleomorphic adenoma of soft palate with cavernous sinus invasion

<p>Abstract</p> <p>Background</p> <p>Carcinoma ex pleomorphic adenoma (CXPA) is an aggressive salivary gland malignancy and rare in minor salivary gland. A soft palate CXPA initially presenting as direct cavernous sinus (CS) invasion is very rare.</p> <p>Case Presentation</p> <p>A 60-year-old male had a 3-month history of a small soft palatal mass with progressing left cheek numbness, proptosis, and disturbed vision. Biopsy of soft palatal tumor showed pleomorphic adenoma. Magnetic resonance imaging showed a tumor involving left maxilla, and extended from pterygopalatine fossa, inferior orbital fissure to CS. Excision of tumor revealed CXPA. Adjuvant concomitant chemo-radiation therapy (CCRT) was given. The tumor recurred 5 months later in left CS which was re-treated with CCRT. The disease status was stable at 2 years after the diagnosis of CXPA.</p> <p>Conclusion</p> <p>We present this case to emphasize that patients with symptoms such as facial numbness, proptosis and disturbed vision should be carefully investigated for lesions invading CS by perineural spread.</p

Love Postoperative ECG Shell (I)

Ongoing cutting-edge multidisciplinary research in textile fibers, biomedical sensors, and wireless and mobile telecommunications integrated with telemedicine, aims at developing intelligent biomedical clothing (IBC). This ECG shell design is a functional garment offering, health benefits, improved appearance and increased comfort. The garment is more comfortable because the high adhesive factor of current commercial hydrogel used in ECG monitoring causes patients skin allergies and pruritus from wearing the hydrogel for a long time

Love Postoperative ECG T-shirt (II)

This ECG T-shirt is a functional garment offering, health benefits, improved appearance and increased comfort. The garment is more comfortable because the high adhesive factor of current commercial hydrogel used in ECG monitoring causes patients skin allergies and pruritus from wearing the hydrogel for a long time. Additionally, since the sensors are attached to the lining of this two-layer raglan T-shirt, the exterior is smooth and makes the user tracking device inconspicuous

A topological insulator surface under strong Coulomb, magnetic and disorder perturbations

Three dimensional topological insulators embody a newly discovered state of matter characterized by conducting spin-momentum locked surface states that span the bulk band gap as demonstrated via spin-resolved ARPES measurements . This highly unusual surface environment provides a rich ground for the discovery of novel physical phenomena. Here we present the first controlled study of the topological insulator surfaces under strong Coulomb, magnetic and disorder perturbations. We have used interaction of iron, with a large Coulomb state and significant magnetic moment as a probe to \textit{systematically test the robustness} of the topological surface states of the model topological insulator Bi$_2$Se$_3$. We observe that strong perturbation leads to the creation of odd multiples of Dirac fermions and that magnetic interactions break time reversal symmetry in the presence of band hybridization. We also present a theoretical model to account for the altered surface of Bi$_2$Se$_3$. Taken collectively, these results are a critical guide in manipulating topological surfaces for probing fundamental physics or developing device applications.Comment: 14 pages, 4 Figures. arXiv admin note: substantial text overlap with arXiv:1009.621
