text: In this paper we propose a new interference alignment (IA) algorithm specifically
designed to work with structured channels (e.g., diagonal or block-diagonal).
Multiple-input multiple-output (MIMO) structured channels arise when symbol extensions
-either in time or frequency- are employed jointly with the spatial dimension
in the design of the precoders. In this case, the rank constraint in the direct
channels must explicitly be taken into account into the optimization problem to
ensure that there is no degrees-of-freedom (DoF) loss. To this end, we propose
an algorithm that minimizes the interference leakage while ensuring that the direct
links are full rank and the transmitters satisfy a power constraint. The algorithm
is based upon an alternating optimization procedure, which solves a generalized
eigenvalue problem at each step. We show through simulations the advantages of
the proposed algorithm in several scenarios that use symbols extensions or improper
(a.k.a. asymmetric) signalling.

text: It has been recently shown that for the 3-user single-input single-output
(SISO) interference channel with constant channel coefficients, a maximum of 1.2
degrees-of-freedom (DoF) are achievable using linear interference alignment schemes
when improper (a.k.a. asymmetric) Gaussian signaling is applied. In this paper,
we study the 4-user SISO interference channel and provide inner and outer bounds
for the total number of DoF achievable for this channel. We prove that at least
4/3 DoF are achievable for the 4-user channel using also linear interference alignment
techniques and improper signaling. A simple converse proof shows that no more
than 8/5 DoF are achievable for this scheme. Simulation results seem to indicate
that the inner bound is in fact tight for this channel, and serve to illustrate
the sum-rate improvement with respect to time division multiple access (TDMA)
techniques.

text: Texture analysis of light scattering in tissue is proposed to obtain diagnostic
information from breast cancer specimens. Light scattering measurements are minimally
invasive, and allow the estimation of tissue morphology to guide the surgeon in
resection surgeries. The usability of scatter signatures acquired with a micro-sampling
reflectance spectral imaging system was improved utilizing an empirical approximation
to the Mie theory to estimate the scattering power on a per-pixel basis. Co-occurrence
analysis is then applied to the scattering power images to extract the textural
features. A statistical analysis of the features demonstrated the suitability
of the autocorrelation for the classification of notmalignant (normal epithelia
and stroma, benign epithelia and stroma, inflammation), malignant (DCIS, IDC,
ILC) and adipose tissue, since it reveals morphological information of tissue.
Non-malignant tissue shows higher autocorrelation values while adipose tissue
presents a very low autocorrelation on its scatter texture, being malignant the
middle ground. Consequently, a fast linear classifier based on the consideration
of just one straightforward feature is enough for providing relevant diagnostic
information. A leave-one-out validation of the linear classifier on 29 samples
with 48 regions of interest showed classification accuracies of 98.74% on adipose
tissue, 82.67% on non-malignant tissue and 72.37% on malignant tissue, in comparison
with the biopsy H and E gold standard. This demonstrates that autocorrelation
analysis of scatter signatures is a very computationally efficient and automated
approach to provide pathological information in real-time to guide surgeon during
tissue resection.

text: Fractal analysis combined with a label-free scattering technique is proposed
for describing the pathological architecture of tumors. Clinicians and pathologists
are conventionally trained to classify abnormal features such as structural irregularities
or high indices of mitosis. The potential of fractal analysis lies in the fact
of being a morphometric measure of the irregular structures providing a measure
of the object’s complexity and self-similarity. As cancer is characterized by
disorder and irregularity in tissues, this measure could be related to tumor growth.
Fractal analysis has been probed in the understanding of the tumor vasculature
network. This work addresses the feasibility of applying fractal analysis to the
scattering power map (as a physical modeling) and principal components (as a statistical
modeling) provided by a localized reflectance spectroscopic system. Disorder,
irregularity and cell size variation in tissue samples is translated into the
scattering power and principal components magnitude and its fractal dimension
is correlated with the pathologist assessment of the samples. The fractal dimension
is computed applying the box-counting technique. Results show that fractal analysis
of ex-vivo fresh tissue samples exhibits separated ranges of fractal dimension
that could help classifier combining the fractal results with other morphological
features. This contrast trend would help in the discrimination of tissues in the
intraoperative context and may serve as a useful adjunct to surgeons.

text: The paper deals with global stability analysis of linear control systems with
saturation in feedback driven by an external input. Various new criteria based
on non-quadratic Lyapunov functions are proposed, that unlike many previous results,
offer better account for the role of the external excitation by providing input-dependent
conditions for stability of solutions. For example, it is shown that even if the
system fails to satisfy the incremental version of the circle criterion, the stability
is guaranteed whenever the uniform root mean square value of the input signal
is less than a computable threshold. The general theoretical results are illustrated
in the case of the double integrator closed by a saturated linear feedback with
an external excitation.

text: In this paper we study the existence of locally most powerful invariant tests
(LMPIT) for the problem of testing the covariance structure of a set of Gaussian
random vectors. The LMPIT is the optimal test for the case of close hypotheses,
among those satisfying the invariances of the problem, and in practical scenarios
can provide better performance than the typically used generalized likelihood
ratio test (GLRT). The derivation of the LMPIT usually requires one to find the
maximal invariant statistic for the detection problem and then derive its distribution
under both hypotheses, which in general is a rather involved procedure. As an
alternative, Wijsman’s theorem provides the ratio of the maximal invariant densities
without even finding an explicit expression for the maximal invariant. We first
consider the problem of testing whether a set of N-dimensional Gaussian random
vectors are uncorrelated or not, and show that the LMPIT is given by the Frobenius
norm of the sample coherence matrix. Second, we study the case in which the vectors
under the null hypothesis are uncorrelated and identically distributed, that is,
the sphericity test for Gaussian vectors, for which we show that the LMPIT is
given by the Frobenius norm of a normalized version of the sample covariance matrix.
Finally, some numerical examples illustrate the performance of the proposed tests,
which provide better results than their GLRT counterparts.

text: In this paper, we study the multiple-input multiple-output two-way relay channel
(MIMO-TWRC) when the nodes and relay use analog beamforming. Following the amplify-andforward
(AF) strategy, the problem consists of finding the transmit and receive beamformers
of the nodes and relay (as well as the power allocated to each one) that achieve
the boundary of the optimal rate region. To solve it, we first express the optimal
node beamformers in terms of relay beamformers and then show that the optimal
rate region can efficiently be characterized using convex optimization techniques.
We also extend our study to the multiple-relay scenario when the source nodes
are single antenna and propose a distributed algorithm to compute the relay beamforming
matrices. The proposed algorithm consists of solving two different subproblems.
First, each individual TWRC is optimized independently. Next, a distributed beamforming
is applied to make the signals from the relays add up coherently at the source
nodes. Numerical examples are provided to illustrate the performance of the proposed
techniques and to compare the performance of analog beamforming architectures
against conventional MIMO schemes that operate at the baseband.

text: In this paper we provide an efficient procedure to compute the total number
of degrees of freedom (DoF), achievable by linear beamforming, of the $K$-user
multiple-input multiple-output (MIMO) interference channel with an arbitrary number
of Tx-Rx antennas at each link. Firstly, we derive an analytical outer bound that
generalizes the results that exist for the symmetric $K$-user $M\timesN$ interference
channel. Secondly, we obtain a tighter bound by solving a convex optimization
problem that includes as constraints the DoF characterizations for point-to-point
MIMO links and for 2-user interference channels. The solution to this convex problem
admits an interesting waterfilling interpretation. Finally, exploiting this outer
bound and using a recently proposed feasibility test, we show that it is possible
to obtain the DoF for any interference channel in an efficient way. Some simulations
results are included to illustrate the tightness of the derived bounds, as well
as to study the DoF achievable for the 4-user channel when we distribute the total
number of antennas among users and between transmitters and receivers in different
ways.

text: This paper gives a solution to the problem of verifying stability of networks
consisting of integral input-to-state stable (iISS) subsystems. The iISS small-gain
theorem developed recently has been restricted to interconnections of two subsystems.
For large-scale systems, stability criteria relying only on gain-type information
that were previously developed address only input-to-state stable (ISS) subsystems.
To address the stability problem involving iISS subsystems interconnected in general
structure, this paper shows how to construct Lyapunov functions of the network
by means of a sum of nonlinearly rescaled individual Lyapunov functions of subsystems
under an appropriate small-gain condition.

text: This work presents a variation of canonical correlation analysis (CCA), where
the correlation coefficient between the instantaneous power of the projections
is maximized, rather than between the projections themselves. The resulting optimization
problem is not convex, and we have to resort to a sub-optimal approach. Concretely,
we propose a two-step solution consisting of the singular value decomposition
(SVD) of a "coherence" matrix followed by a rank-one matrix approximation. This
technique is applied to blindly recovering signals in a model that is motivated
by the study of neuronal dynamics in humans using electroencephalography (EEG)
and magnetoencephalography (MEG). A distinctive feature of this model is that
it allows recovery of amplitude-amplitude coupling between neuronal processes.
