A continuation method for tensor complementarity problems
We introduce a Kojima-Megiddo-Mizuno type continuation method for solving
tensor complementarity problems. We show that there exists a bounded
continuation trajectory when the tensor is strictly semi-positive and any limit
point tracing the trajectory gives a solution of the tensor complementarity
problem. Moreover, when the tensor is strong strictly semi-positive, tracing
the trajectory will converge to the unique solution. Some numerical results are
given to illustrate the effectiveness of the method.Comment: 15 pages, 4 table
Effects of Shenque Moxibustion on Behavioral Changes and Brain Oxidative State in Apolipoprotein E-Deficient Mice
Purpose. To determine whether moxibustion influences the learning and memory behavior of ApoE−/− male mice, and investigate the mechanism of moxibustion on the alteration of oxidized proteins (glial fibrillary acidic protein, β-amyloid) in hippocampus. Methods. Thirty-three ApoE−/− mice were randomly divided into 3 groups (n=11/group): moxibustion, sham moxibustion, and no treatment control. Wild-type C57BL/6 mice n=13 were used for normal control. Moxibustion was performed with Shenque (RN8) moxibustion for 20 minutes per day, 6 days/week for 12 weeks. In sham control, the procedure was similar except burning of the moxa stick. Behavioral tests (step-down test and Morris water maze task) were conducted in the 13th week. The mice were then sacrificed and the tissues were harvested for immune-histochemical staining. Results. In the step-down test, the moxibustion group had shorter reaction time in training record and committed less mistakes compared to sham control. In immune-histochemical study, the moxibustion group expressed lower level of GFAP and less aggregation of β-amyloid in the hippocampus than the sham control. Conclusion. Our findings suggest that moxibustion may enhance learning capability of ApoE−/− mice. The mechanism may be via inhibiting oxidized proteins (GFAP and β-amyloid) in astrocytes
High speed self-testing quantum random number generation without detection loophole
Quantum mechanics provides means of generating genuine randomness that is
impossible with deterministic classical processes. Remarkably, the
unpredictability of randomness can be certified in a self-testing manner that
is independent of implementation devices. Here, we present an experimental
demonstration of self-testing quantum random number generation based on an
detection-loophole free Bell test with entangled photons. In the randomness
analysis, without the assumption of independent identical distribution, we
consider the worst case scenario that the adversary launches the most powerful
attacks against quantum adversary. After considering statistical fluctuations
and applying an 80 Gb 45.6 Mb Toeplitz matrix hashing, we achieve a
final random bit rate of 114 bits/s, with a failure probability less than
. Such self-testing random number generators mark a critical step
towards realistic applications in cryptography and fundamental physics tests.Comment: 34 pages, 10 figure
A desinstitucionalização e as alternativas habitacionais ao dispor de indivÃduos com perturbações mentais: Um novo modelo habitacional – A habitação apoiada
Desde o inÃcio do processo de desinstitucionalização desinstitucionalização
que este se tem vindo a deparar com dificuldades.
Passando pelos poucos recursos ao dispor dos serviços
de saúde mental, à tendência para trabalhar com os
elementos que apresentam maiores probabilidades de
sucesso, à não articulação entre os serviços hospitalares
e os centros comunitários de saúde mental, até Ã
falta de investimentos em alternativas habitacionais de
carácter permanente. Estas têm sido algumas das situações
a que os consumidores de serviços de saúde mental
se têm sujeitado.
Actualmente, assistimos à emergência de um paradigma
que assenta na crença de que se deverá prestar
apoio a estes consumidores numa casa tipicamente
normal, com uma vivência na comunidade, em que o
apoio é disponibilizado consoante as necessidades de
cada indivÃduo sem que exista uma limitação temporal
à sua prestação. Torna-se assim necessário criar novos
papéis para os técnicos, no sentido de que estes ajudem
os consumidores a escolher, a obter, e a manter
uma habitação. É pois urgente o desenvolvimento de
um conjunto diversificado de alternativas habitacionais
que se baseiem nos recursos e capacidades das comunidades
locais, no sentido de garantir que o processo
de desinstitucionalização se conclua com sucesso.
Palavras-chave: desinstitucionalização, habitação
apoiada, satisfação dos consumidores, doença mental.ABSTRACT: Since its beginning the deinstitutiondeinstitutionalization process
has faced some difficulties, such as the mental
health services lack of resources, the trend to work
with the individual who presents higher probability of
success, the lack of articulation between hospital services
and community mental health centers, and the
lack of investments on accommodations for long periods
of time. These are some of the situations that
consumers of mental health services have endured.
Nowadays we witness the emerging of a paradigm
which lies on the idea that these consumers need to be
supported at a ordinary house, living in community,
where the support is provided according to each person’s
needs, and without a time limit. This paradigm
also creates a need for the professionals to find new
roles so that they will be able to help the consumers to
choose, get, and keep a home. To ensure the success of
deinstitutionalization it is vital that the establishment
of different alternatives of accommodation be based on
communities’ resources and capabilities.info:eu-repo/semantics/publishedVersio
Field demonstration of distributed quantum sensing without post-selection
Distributed quantum sensing can provide quantum-enhanced sensitivity beyond
the shot-noise limit (SNL) for sensing spatially distributed parameters. To
date, distributed quantum sensing experiments have been mostly accomplished in
laboratory environments without a real space separation for the sensors. In
addition, the post-selection is normally assumed to demonstrate the sensitivity
advantage over the SNL. Here, we demonstrate distributed quantum sensing in
field and show the unconditional violation (without post-selection) of SNL up
to 0.916 dB for the field distance of 240 m. The achievement is based on a
loophole free Bell test setup with entangled photon pairs at the averaged
heralding efficiency of 73.88%. Moreover, to test quantum sensing in real life,
we demonstrate the experiment for long distances (with 10-km fiber) together
with the sensing of a completely random and unknown parameter. The results
represent an important step towards a practical quantum sensing network for
widespread applications.Comment: 8 pages, 5 figure
