High-resolution imaging through randomly dynamic scattered fields and highly scattered walls is an extensively sought-after capability with potential applications in various fields such as underwater imaging, biomedical imaging, and seeing through fog. Numerous methods have been proposed to unscramble object information from degraded scattered images, resulting in considerable improvements in image contrast in degraded scenarios [1].

The anti-forcing number of a perfect matching M of a graph G is the minimal number of edges not in M whose removal makes M a unique perfect matching of the resulting graph. The anti-forcing spectrum of G is the set of anti-forcing numbers over all perfect matchings of G. In this paper, we prove that the anti-forcing spectrum of any cata-condensed hexagonal system is continuous, that is, it is a finite set of consecutive integers.

Landscape evolution is the window to the link between deep earth and surface processes. One of the key issues in landscape evolution is to characterize the topographic steady state of mountain belts. The Taiwan mountain belt is an extraordinary case due to its extremely high uplift and denudation rates. The uplift of Taiwan Island is caused by the oblique collision between the Luzon Arc and the East Asian continent. In this case, the mountain building process in the north always occurs earlier than that in the south,which causes the spatial distribution of steady-state *** East Central Range receives much research attention with the presence of river basins that mainly distribute along the trajectory of the collision propagation. Normally, based on analyses of geomorphic parameters, the whole Central Range, or at least part of it, should be at a topographic steady state. However, the balance between uplift rates and denudation rates that exist in these regions is seldomly tested. In this contribution, we make a comprehensive literature review on the uplift and denudation rates derived from various approaches, including sediment yields, in-situ cosmogenic nuclide ^(10) Be, incision of river channels,thermochronology, and GPS observations. This literature review reveals that the topographic steady state may prevail in the northern and middle parts of the East Central ***, an obvious inconsistency in denudation rates calculated by different methods prevents us from better constraining the topographic steady state in some regions of this mountain range.

Rather than using existing self-interference cancellation methods, which essentially consist of reconstruction and subtraction, this paper proposes a novel approach, based on multiplication, to cancel selfinterference in the analog domain in full-duplex communications. This approach is called self-mixed selfinterference analog cancellation(SM-SIAC). Moreover, rather than using an individual analog cancellation circuit in existing self-interference cancellation methods, SM-SIAC can merge the analog cancellation circuit and the receiver. SM-SIAC is configured with three auto-tuning loops, consisting of one delay loop and two gain loops. SM-SIAC is further simplified with the Gaussian minimum shift keying(GMSK) self-interference *** these loops converge, the paper analyzes the cancellation capacity and derives a closed-form expression for the quadrature amplitude modulation self-interference signal and the GMSK self-interference signal. Simulation results illustrate the convergence of the gain loops and the cancellation capacity in the presence of engineering errors.

Objective： To explore the effectiveness and safety of acupuncture in patients with post-stroke dysphagia by an update meta-analysis. Methods： Potentially eligible RCTs aimed to evaluate the effects of acupuncture vs. non-acupuncture treatments, such as rehabilitation training or routine medication on the swallowing difficulty after stroke were searched from PubMed, Cochrane Library, China National Knowledge Infrastructure, and other database from the earliest record to June 2016. Patient demographics, regimens for acupuncture, type of controls, methods of randomization, and measurements of the clinical symptoms of dysphagia were retrieved. The relative risk （RR） and 95% confidence interval （CI） of effective rate of dysphagia was calculated after intervention performed following admission. Subgroup analyses and a meta- regression analysis were performed to describe the heterogeneity. Results： Twenty-nine RCTs comprising 2,190 patients were included. The included studies had a medium quality grade based on the Consolidated Standards of Reporting Trials （CONSORT） and Standards for Reporting Interventions in Clinical Trials of Acupuncture （STRICTA） checklist. Acupuncture therapy provided a higher effective rate compared with non- acupuncture treatments [RR=1.33, 95% confidence interval （CI）, 1.25 to 1.43]. Subgroup and meta-regression analyses suggested that acupuncture intensity and measurement method were main sources of heterogeneity and resulted in a significant difference for pooled effect size. No severe adverse events were documented in these RCTs. Conclusions： Our meta-analysis provides a new evidence supporting the efficacy and safety of acupuncture in treatment to post-stroke dysphagia in short-term compared with rehabilitation or medication. More high-quality and large-scale research studies are needed.

The multi-color photometric light curves for contact binary AV Puppis(AV Pup) in VRcIc bandpasses are presented and analyzed by using the 2013 version of the Wilson-Devinney(W-D) *** solutions suggest that AV Pup is a peculiar A-subtype W UMa contact binary with a high mass ratio(q = m2/m1 = 0.896) and a low fill-out factor(f = 10%). Combining our newly determined times of minimum with those collected from literatures, the orbital period changes of this system are investigated. The O-C analysis indicates that the orbital period of AV Pup is increasing at a rate of d P/dt = 4.83 × 10-7 days yr-1, which can be explained by mass transfer from the less massive component to the more massive one.

Masses of W Ursae Majoris-type(W UMa) binaries play a critical role in investigating stellar dynamical evolutionary status. In this paper, we combine the PARSEC(PAdova and TRieste Stellar Evolution Code) with the Roche geometric model to provide a method to determine the masses of W UMa systems. To verify the validity of this method, we compile a sample of 140 spectrum binaries from the literature, which includes 76 W-and 64 A-subtype systems with reliable physical parameters. We find that the average fractional difference and the standard deviation(σM) of the residuals for W-subtype and Asubtype approximately amount to 15.66% and 0.1218, 16.03% and 0.2094, respectively. Meanwhile, we also perform detailed analyses in accordance with the orbital period, the effective temperatures and the mass ratio. We find that the method is more applicable to determine masses for W UMa systems with low effective temperature and short period.
