Abstract
Objective The present study aims to determine if the use of cervical pessary plus progesterone in short-cervix (≤ 25 mm) dichorionic-diamniotic (DC-DA) twin pregnancies is equivalent to the rate of preterm births (PBs) with no intervention in unselected DC-DA twin pregnancies.
Methods A historical cohort study was performed between 2010 and 2018, including a total of 57 pregnant women with DC-DA twin pregnancies. The women admitted from 2010 to 2012 (n = 32) received no treatment, and were not selected by cervical length (Non-Treated group, NTG), whereas those admitted from 2013 to 2018 (n = 25), were routinely submitted to cervical pessary plus progesterone after the diagnosis of short cervix from the 18th to the 27th weeks of gestation (Pessary-Progesterone group, PPG). The primary outcome analyzed was the rate of PBs before 34 weeks.
Results There were no statistical differences between the NTG and the PPG regarding PB < 34 weeks (18.8% versus 40.0% respectively; p = 0.07) and the mean birthweight of the smallest twin (2,037 ± 425 g versus 2,195 ± 665 g; p = 0.327). The Kaplan-Meyer Survival analysis was performed, and there were no differences between the groups before 31.5 weeks. Logistic regression showed that a previous PB (< 37 weeks) presented an odds ratio (OR) of 15.951 (95% confidence interval [95%CI]: 1.294–196.557; p = 0.031*) for PB < 34 weeks in the PPG.
Conclusion In DC-DA twin pregnancies with a short cervix, (which means a higher risk of PB), the treatment with cervical pessary plus progesterone could be considered equivalent in several aspects related to PB in the NTG, despite the big difference between these groups.
ISR for T1-2 Low Rectal Cancer: A Japanese Approach
Authors: Ito Masaaki 
Published: November 2020

AbstractThe evolution over the past 20 years of anal preservation in rectal cancer surgery has been truly remarkable. Intersphincteric resection (ISR) reported by Schiessel in 1994 in Australia has been shown to enable anal preservation even for cancers quite close to the anus. In Japan, ISR via the detachment of the anal canal between the internal and external sphincters and excision of the internal sphincter first began to be practiced in the latter half of 1990. A multicenter Phase II trial of ISR in Japan suggested that 70% of the cases had relatively good function with less than 10 points of Wexner score but around 10% had severe incontinence that would not be improved for long term. The primary end point of the clinical study, 3-year local recurrence rate, was 13.2% across the overall cohort (T1, 0%; T2, 6.9%; and T3, 21.6%). When ISR is performed on T1/T2 rectal cancers, sufficient circumferential resection margin can be obtained even without preoperative chemoradiotherapy, and local recurrence rate was acceptably low. Based on these evidences, ISR is a currently important, standard treatment option among anal-preserving surgeries for T1/T2 low-lying rectal cancers. In Japan, a feasibility study (LapRC trial) of laparoscopic ISR on Stage 0 and Stage 1 low rectal cancer showed excellent outcomes. A prospective Phase II clinical trial targeting low rectal cancers within 5 cm from the anal verge (ultimate trial) is being performed and awaiting the results in near future.

Authors: Hernández-Vásquez Akram , Bendezu-Quispe Guido , Comandé Daniel , Gonzales-Carillo Oswaldo 
Published: October 2020

Abstract
Objective To evaluate the global productivity regarding original articles on maternal near-miss (MNM).
Methods We conducted a bibliometric analysis of original articles published from 2008 to November 2019 in the journals indexed in the Scopus database. The averages of the number of articles by author, of the number of authors by article, of the number of citations by article, and the total number of documents with one or more authors were obtained. An analysis of the co-citation of authors and a co-occurrence analysis of the terms included in the titles and abstracts were performed and were presented as network visualization maps.
Results A total of 326 original articles were analyzed. There was an increase in the number of articles (p < 0.001; average annual growth rate = 12.54%). A total of 1,399 authors, an average number of articles per author of 4.29, with an index of authors per document of 0.23, and an index of co-authors per document of 8.16 were identified. A total of 85 countries contributed with original articles on MNM. Among the top ten countries regarding the contribution of articles, five were low and middle-income countries (LMICs). Brazil had the highest volume of production (31.1%), followed by the US (11.5%). Terms related to countries and the measurement of the rates and cases of MNM and the associated factors were found in recent years in the analysis of the co-occurrence of terms.
Conclusion There was an increase in the production of original articles on MNM, with a significant participation of authors and institutions from LMICs, which reveals a growing interest in the use of MNM indicators to improve the quality of maternal health care.

Authors: Easter Tim G. , Pink Jonathan J. , Oxley Bill , Bilmont Alexis 
Published: October 2020

Abstract
Objective The aim of this study was to report the surgical technique and outcomes of dogs with type V central tarsal bone (CTB) fractures stabilized with a bone plate applied to the medial aspect of the tarsus and metatarsus.
Study Design This study was a retrospective review of dogs with type V CTB fractures diagnosed with computed tomography and stabilized using a medial bone plate. Follow-up included clinical examination and radiography 8 to 10 weeks postoperatively and/or a long-term owner questionnaire.
Results Six dogs were identified. All fractures occurred during exercise without external trauma and all dogs had additional tarsal fractures. Five dogs returned for clinical follow-up; all had no or mild lameness and evidence of fracture healing on radiography. A suspected surgical site infection occurred in one dog and resolved with medical management. Suspected contact between the plate and medial malleolus in one dog, and loosening of a talar screw in another, were identified, though not treated. Five owners completed the questionnaire, a median of 88 months postoperatively. No further complications were reported, limb function was reportedly acceptable, and all owners were very satisfied with the surgery.
Conclusion Medial bone plate stabilization of highly comminuted CTB fractures resulted in evidence of fracture healing, and a low incidence of complications in six non-racing dogs.

Published: October 2020

AbstractObjective The aim of this study was to compare the resulting short-term complications after simultaneous (SIM) or staged (ST) tibial plateau levelling osteotomy (TPLO) in patients that presented with bilaterally torn cranial cruciate ligaments.Study Design This was a retrospective study.Materials and Methods Medical records of dogs diagnosed with bilateral cranial cruciate ligament disease that underwent bilateral SIM or ST TPLO surgery with arthroscopy (2005–2015) were reviewed to evaluate the intra- and postoperative complications. Data were analysed and major and minor complications were compared between the two groups.Results A total of 176 client-owned dogs (352 stifles) that had TPLO performed bilaterally with SIM or ST procedures were included for analysis. The overall complication rate was 47.5% for the SIM group and 19.5% for the ST group. The incidence of major complications was 10.1 and 3.8% in the SIM and ST groups respectively. Minor complications were 38.4 and 15.6% in the SIM and ST groups respectively. Tibial tuberosity fractures requiring revision were noted in 2% of the SIM group and none of the ST group.Clinical Significance Although no significant difference was noted in major complication rate or tibial tuberosity fractures in our cohort of patients, a Type II statistical error was found. The complication rate in the SIM group is numerically greater by a factor of 2–3× or more for nearly all categories. Surgeons should consider the risks and benefits of SIM versus ST procedures as well as relevant individual patient and client factors before electing either alternative.
Coronavirus 2019, Thrombocytopenia and HELLP Syndrome: Association or Coincidence?
Authors: Braga Luiz Felipe Bagnatori , Sass Nelson 
Published: October 2020

AbstractThe present report describes the case of a 31-year-old primigravida, with dichorionic twins at 31 weeks. She presented with history of myalgia, jaundice, and abdominal discomfort. No flu-like symptoms as fever or cough. She was not aware of exposure to COVID-19. Normal blood pressure and O2 saturation. Laboratory tests showed platelet count of 218,000 mm3, alanine aminotransferase (ALT) 558 IU and serum creatinine 2.3 mg/dl. Doppler ultrasound in one twin was compatible with brain sparing. Partial hemolysis, elevated liver enzymes, low platelet count (HELLP) syndrome was the hypothesis, and a cesarean section was performed. On day 2, the white-cell count reached 33,730, with decreased consciousness and mild respiratory distress. Tomography revealed both lungs with ground-glass opacities. Swab for COVID-19 polymerase chain reaction (PCR) was positive. Thrombocytopenia in patients with COVID-19 appears to be multifactorial, similar to what occurs in preeclampsia and HELLP syndrome. We assume that the synergism of these pathophysiological mechanisms could accelerate the compromise of maternal conditions and could be a warning to the obstetric practice.

Published: October 2020

Abstract
Background There has been increasing interest in the superficial circumflex iliac artery perforator (SCIP) flap as a source of thin, pliable soft tissue combined with a favorable donor site. Despite several clinical series from Asia, barriers to adoption include reluctance to perform submillimeter “supermicrosurgery” and the effect of body habitus on flap feasibility. The purpose of this study is to distinguish vascular anatomic characteristics of the SCIP flap in a North American population.
Methods Computed tomography angiography was examined in 84 flaps in healthy prospective renal donor patients from a radiographic database. Descriptive statistics as well as linear regression comparing variables to body mass index (BMI) were performed.
Results Mean BMI was 27.1 ± 3.5 kg/m2, while the mean patient age was 47.8 ± 11.4 years. The superficial circumflex iliac artery (SCIA) originated from the common femoral artery in 92% cases, with remainder originating from the profunda femoris. The mean vessel diameter was 1.85 mm at source vessel origin. Distance from skin to source vessel averaged 30.7 mm. Suprascarpal subcutaneous thickness averaged 16.5 mm. The mean distance from Scarpa's fascia to vessel origin was 14.1 mm. Direct three-dimensional distance from vessel origin to pubic tubercle was 50.2 mm. A medial and lateral perforator split off of the SCIA was observed in 38 cases (45%). Significant differences were shown when comparing BMI to skin to source vessel distance (p < 0.001), suprascarpal subcutaneous fat thickness (p < 0.001), and fascial distance to vessel origin (p < 0.001). BMI did not significantly affect vessel diameter.
Conclusion Despite a significantly higher BMI than many previously published cohorts, the SCIP remains an excellent source of thin and pliable tissue. When dissected closer to the source vessel, a vessel caliber of nearly 2 mm can be achieved, which may obviate the need for “supermicrosurgery” in this population.

Published: October 2020

SignificanceMany physiological processes are driven by changes across heterogeneous populations of cells. However, we currently lack a conceptual framework for comparing single-cell transcriptional data collected from populations as they respond to perturbations. Here, we develop a framework, called PopAlign, that models a cell population as a probability distribution in gene-expression space. Individual subpopulations are represented as local densities that are statistically aligned across samples. The models present an integrated representation that allows comparisons at multiple scales, from gene-expression programs to cell state to population structure. The models are memory-efficient and can be scaled across hundreds of samples, which we demonstrate using public data and data from human immune cells responding to drugs and disease.
The rise of prosociality in fiction preceded democratic revolutions in Early Modern Europe
Authors: Martins Mauricio de Jesus Dias , Baumard Nicolas 
Published: October 2020

SignificanceWe analyzed a large sample of English and French theatre plays and tracked the dynamics of words related to cooperation and dominance before and after early modern revolutions. We show that prior to both the English Civil War and French Revolution, there was a sharp rise in the frequency of words associated with prosociality, trustworthiness, and sympathy vs. words related to authoritarianism, strength and anger. Interestingly, in postrevolutionary reactionary periods, characters became stronger and less trustworthy. Finally, we also show that variations in GDP per capita partially account for these psychological changes. These findings reveal the interplay between economic environment, psychological preferences, and political events and shed lights on the rise and fall of support for democracy.
In situ imaging of two-dimensional surface growth reveals the prevalence and role of defects in zeolite crystallization
Authors: Choudhary Madhuresh K. , Jain Rishabh , Rimer Jeffrey D. 
Published: October 2020

Significance
Recent studies have shown that switching from a nonclassical to classical pathway in zeolite crystallization can impact material properties for improved performance in commercial applications, yet few studies have examined zeolite growth by a purely classical mechanism. Here we identify conditions of zeolite crystallization by molecule addition using high-temperature atomic force microscopy to elucidate modes of surface growth with high spatiotemporal resolution. In situ observations reveal that defects, such as silica nanoparticle occlusions, are recurrent in zeolite A crystallization. We posit these defects may be a general outcome of zeolite synthesis that evade detection by conventional techniques, creating amorphous obstructions within pores that, if present in sufficient quantity, can negatively impact zeolite performance in applications ranging from catalysis to separations.

Authors: Wang Keren , Li Weihao 
Published: October 2020

Abstract
Wideband signal detection plays an important role in wireless communication systems. In recent years, deep learning (DL) has been introduced, and many trial efforts have been posed. In this paper, a fast deep-learning signal detection architecture is proposed for the short-wave band, which consists of the GPU-based Down Digital Converter (DDC), the DL-based signal detector, and the signal data viewer & recorder. Wideband signal data are taken directly as the input, and detected signals are automatically recorded as the output of the architecture. Experimental results suggest that our architecture is capable of detecting signals in the whole short-wave band in quasi-real-time, and specifically, with single GPU device.

Abstract
Traditional fine forest survey methods mainly rely on ground surveys and use remote sensing image to estimate, which has problems such as low efficiency, poor data objectivity, difficult to unifiy standard control, and low degree of automation. Based on the DEM, DSM, lidar point cloud, and tilt photography model from multiple sources and resolutions, by superimposing high-resolution remote sensing image and selecting eight representative evaluation indicators such as distribution interpretation, species legibility, vegetation penetration ability and parameter extractability, this paper analyzed the advantages and disadvantages of forest resource surveys under these methods and proposed a fast and high-precision method for fine forest resources sruvey. The results showed that the forest resource survey based on lidar technology can meet the needs of fine forest resources survey and can be used for fine forest resources survey.

Published: October 2020

Abstract
The security of the original measurement-device-independent quantum key distribution (MDI-QKD), immune to all possible side channel detector attacks, is relied on the assumption that legitimate users, called Alice and Bob, can control their sources exactly. However, this might always not be satisfied in today’s state of the art. Later, one of us has proposed a MDI-QKD with uncharacterized coherent pulses, and shows that MDI-QKD can cover long distances securely with imperfect current sources. In this paper, relied on the basic imperfect sources assumption of the former work, we propose an improved one by applying a technique of imperfect phase region matching. We focus on deriving the bound of secrete key rate for this improved protocol, and simulation results show that the improved MDI-QKD can achieve much more better performances than the former one. It pushes the MDI-QKD a step forward to be more practical in more device independent scenario.
Research on FDI Attacks in Edge Computing Environment

Published: October 2020

Abstract
The False Data Injection (FDI) attack in the smart grid can bypass the bad data detection mechanism and make the control center make an incorrect estimate of the system status. The smart grid under the edge computing architecture is more likely to be maliciously attacked by the terminal because it is close to the terminal. For this reason, this paper proposes a method combining PCA and ReliefF algorithm to achieve the purpose of dimensionality reduction. It can solve the overfitting problem caused by the high dimensionality of traditional machine learning attack signal detection, and it is suitable for terminals with low computing power.

Authors: Cui Wei 
Published: October 2020

Abstract
With the exponential growth of IoT terminals, smartphones, and wearable devices, traditional centralized cloud computing models have been unable to efficiently process data generated by edge devices. In order to meet the challenges, edge computing has been proposed. The location close to the terminal device meets the high computing volume, low latency, privacy requirements of deep learning on edge devices, bandwidth advantages, efficiency and scalability. We first introduced the background and motivation for running AI at the edge of the network, reviewed the basic concepts of deep learning, and then we provided the overall architecture of edge computing based on deep learning. We discussed three computing and inference models on terminal devices, edge servers and cross-edge devices, and describes the method to improve and optimize the edge deep learning model. Finally, we discuss the application scenarios and future opportunities of edge deep learning.

Abstract
In this paper, we study the method of digital image processing as a game task with distributed parameters. The possibilities of formulating digital processing as a differential game of the Dirichlet problem for the Poisson equation are indicated. Replacing the differential game with a discrete game with boundary conditions, sufficient conditions are obtained for the possibility of completing the pursuit. In solving the pursuit problem, Chebyshev polynomials of the second kind are used.
