Left ventricular remodeling in the acute (A, C, E) and chronic group (B, D, F)
A and B. There is significant reduction in fractional shortening following ischemia-reperfusion and persists up to 6 weeks. C and D. There is a trend towards increased end systolic dimension 60 minutes following ischemia. There is progressive dilation of the left ventricle from 1–6 weeks. E and F. The estimated left ventricular mass increased at 3 weeks and progressed at 6 weeks.

Control of Nanomorphology in All-Polymer Solar Cells via Assembling Nanoaggregation in a Mixed Solution
The
formation of interconnected phase-separated domains on sub-20
nm length scale is a key requirement for all-polymer solar cells (all-PSCs)
with high efficiency. Herein, we report the application of crystalline
poly(3-hexylthiophene) (P3HT) nanowires via an <i>O</i>-dichlorobenzene/hexane
mixed solution blended with poly{(9,9-dioctylfluorenyl-2,7-diyl)-<i>alt</i>-[4,7-bis(3-hexylthiophen-5-yl)-2,1,3-benzothiadiazole]-2′,2″-diyl}
(F8TBT) for the first time. The nanomorphology of P3HT:F8TBT all-PSCs
can be controlled by P3HT nanowires. The improved film morphology
leads to enhanced light absorption, exciton dissociation, and charge
transport in all-PSCs, as confirmed by ultraviolet–visible
absorption spectra, X-ray
diffraction, transmission electron microscopy, atomic force microscopy,
and time-resolved photoluminescence spectra. The P3HT nanowire:F8TBT
all-PSCs could achieve a power conversion efficiency of 1.87% and
a <i>V</i><sub>oc</sub> of 1.35 V, both of which are the
highest values for P3HT:F8TBT all-PSCs. This work demonstrates that
the semiconductor nanowires fabricated by the mixed solvents method
is an efficient solution process approach to controlling the nanomorphology
of all-PSCs
Origin of the Anomalous Electrical Transports in Quasi-One-Dimensional Ta<sub>2</sub>NiSe<sub>7</sub>
Exploration
of exotic transport behavior is of great interest and
importance for revealing the properties of the CDW phase of quasi-one-dimensional
Ta2NiSe7. We report the anisotropic electrical
transport properties of Ta2NiSe7 single crystals
in the CDW phase. The anisotropic constant (γ = ρb/ρc) increased
rapidly at TCDW = 60
K upon cooling. The results of the Hall resistivity show that both
the concentrations and mobilities of carriers change abruptly at TCDW. The out-of-plane AMR exhibits C2 and C4 symmetry
components while the in-plane AMR exhibits C2, C4, and C6 at the CDW state. The planar Hall effect is observed in Ta2NiSe7 at low temperature, which is suggested to
originate from the anisotropic orbital magnetoresistance. The calculated
results show that the Fermi surface of Ta2NiSe7 was slightly reconstructed due to the CDW transition. This work
highlights the enhancement of Fermi surface anisotropy during CDW
formation and provides a novel approach to study the CDW materials
