Generally, unitary transformations limit the computational power of quantum finite automata (QFA). In this paper we study a generalized model named one-way general quantum finite automata (1gQFA), in which each symbol in the input alphabet induces a trace-preserving quantum operation, instead of a unitary transformation. Two different kinds of 1gQFA will be studied: measure-once one-way general...

Strong viroid-caused pathogenesis was achieved in tomato cv. Rutgers by biolistic transfer of severe or lethal potato spindle tuber viroid (PSTVd) strains, while other tomato genotypes (e.g., Moneymaker) were tolerant. With reciprocal hybrids between sensitive and tolerant genotypes, we show that plant depression dominates over tolerance. Biolistic transfer of the most pathogenic PSTVd strain A...

The treatment ofschizophrenia was reuolutionizedwith the introduction cfchlorpromaeine in 1952. The dfectiveness qfchlorpromazine in controlling psychotic symptoms lead to the dopamine hypothesis ofschizophrenia, which revolutionized our conceptualization ofthis illness. Si nce that time, numerous typical antipsychotic drugs have been developedfo r the treatment ofschizophrenia. However, the in...

Quantum theory has recently been employed to further advance the theory of information retrieval (IR). A challenging research topic is to investigate the so called quantum-like interference in users’ relevance judgment process, where users are involved to judge the relevance degree of each document with respect to a given query. In this process, users’ relevance judgment for the current documen...

Resumo Introdução A Organização Mundial da Saúde (OMS) recomenda o aleitamento materno exclusivo até 6º mês de vida criança e a sua manutenção com alimentação complementar pelo menos os 2 anos idade. Apesar importância, ingestão substitutos do leite é altamente prevalente, sendo uma preocupação em saúde pública. Objetivo Avaliar associação entre tipos ingeridos estado nutricional no primeiro an...

Estudo abordagem transversal, quantitativo amostra composta por 60 idosas idade > anos do sexo feminino, realizado no Centro Convivência Dos Idosos, localizado em uma cidade Nordeste Brasileiro. Foram estudadas varáveis para avaliação da composição corporal. consumo ...

Introdução: O estado nutricional dos idosos tem um papel importante para caracterizar a qualidade de vida e saúde desta população que possui maior tendência as alterações fisiológicas sociais, doenças crônicas como hipertensão arterial, uso medicamentos, dificuldades com alimentação depressão. Objetivo: analisar associação entre os hábitos alimentares hipertensos usuários uma farmácia municipal...

We prove that the following classes of finitely generated (f.g.) groups have Π1–complete first–order theories: all f.g. groups, the n–generated groups, and the strictly n–generated groups (n > 2). Moreover, all those theories are distinct. Similar techniques show that quasi-finitely axiomatizable (QFA) groups have a hyperarithmetical word problem, where a f.g. group is QFA if it is the only f.g...

The field of quantum information applies the concepts of quantum physics to problems in computer science, and shows great potential for allowing efficient computation. In this thesis I concentrate on a particular quantum information theoretic tool known as the quantum walk. There are two widely studied versions of the quantum walk, the continuous time walk, and the discrete time walk. The discr...
