Flow pumping by external periodic shear applied to a soft interface
Authors: Nezamipour Shima , Najafi Ali 
Published: July 2021

AbstractFlow pumping in viscous fluids is of prime importance in micro-fluidic applications. Here we show that a single colloidal particle in front of a soft wall, manipulated by external means like an optical tweezer, can pump the ambient viscous fluid. The particle, moving back and forth parallel to the soft wall, can produce an averaged net flow in a direction perpendicular to the wall. Using a perturbative scheme, we present the results. Analysis show that this flow in terms of capillary number, scales as $${\text {Ca}}^2$$

AbstractPhoto-selective shading screens are emerging practices that aim to combine crop physical protection with different solar radiation filtration to achieve desired physiological responses. The objective of the present study was to evaluate the effect of photo-selective shading screens on the growth and physiology of purple lettuce for two transplanting seasons in tropical climate in Brazil. A 2 × 4 factorial arrangement was used, being considered the first factor, the transplanting season (spring and fall), and the second factor is the three 35% shading photo-selective shading screens (red, black and silver) and full sun control. The experimental design was a randomized complete block with four replications. The variables studied were: total fresh matter, total dry matter, leaf number, stem diameter, stem length, leaf area, SPAD chlorophyll index, nitrogen balance indexes, chlorophyll, flavonoids and anthocyanins. The photo-selective shading screens influenced the microclimate and the growth variables of purple lettuce, mainly when these plants were sown in the fall. Planting lettuce during spring may result in lower yields due to the higher investment of plants in secondary metabolites to defend against abiotic stress. According to the results, photo-selective shading screens are an appropriate agronomic technique to reduce phenolic compounds and improve lettuce cultivation conditions and can be implemented within protected cultivation practices to improve crop performance.

Published: July 2021

AbstractColorectal cancer (CRC) ranks fourth among the deadliest cancers globally, and the progression is highly affected by the tumor microenvironment (TME). This study explores the relationship between TME and colorectal cancer prognosis and identifies prognostic genes related to the CRC microenvironment. We collected the gene expression data from The Cancer Genome Atlas (TCGA) and calculated the scores of stromal/immune cells and their relations to clinical outcomes in colorectal cancer by the ESTIMATE algorithm. Lower immune scores were significantly related to the malignant progression of CRC (metastasis, p = 0.001). We screened 292 differentially expressed genes (DEGs) by dividing CRC cases into high and low stromal/immune score groups. Functional enrichment analyses and protein–protein interaction (PPI) networks illustrated that these DEGs were closely involved in immune response, cytokine–cytokine receptor interaction, and chemokine signaling pathway. Six DEGs (FABP4, MEOX2, MMP12, ERMN, TNFAIP6, and CHST11) with prognostic value were identified by survival analysis and validated in two independent cohorts (GSE17538 and GSE161158). The six DEGs were significantly related to immune cell infiltration levels based on the Tumor Immune Estimation Resource (TIMER). The results might contribute to discovering new diagnostic and prognostic biomarkers and new treatment targets for colorectal cancer.

Published: July 2021

PurposePeople with mild traumatic brain injury (mTBI) may experience deficits in cognition or communication that go unnoticed by first-line health care providers (FHPs). Speech-language pathologists (SLPs) assess and treat these domains yet are often underrepresented on mTBI multidisciplinary teams. This study's aim was to evaluate FHPs' reported knowledge of and referral practices to SLPs for individuals across the life span with mTBI.MethodPhysicians, physician assistants, nurse practitioners, nurses, and athletic trainers (n= 126) completed an online survey, including two Likert scale questions and one free response question relating to SLPs' role in mTBI.ResultsMore than half of FHPs rate their knowledge of the SLP's role in mTBI management as low (somewhat knowledgeable, 29%; not very knowledgeable, 23%). Similarly, nearly two thirds of FHPs indicated rarely (19%) or never (44%), referring to SLPs for management of patients with mTBI. The majority of FHPs' open responses on the role of the SLP in mTBI management were incomplete, with many including domains that were not relevant to an SLP's role in the management of mTBI (e.g., dysphagia). Within the article, we provide results overall and according to individual profession.ConclusionsResults suggest a majority of FHPs lack knowledge in the role of the SLP in the management of mTBI, which may underpin the low referral patterns reported by FHPs for SLP services. Future educational efforts for FHPs regarding the role of SLPs in mTBI care are necessary.

Published: July 2021

AbstractThis study reports a mid‐infrared Ho3+:BaY2F8 laser directly pumped by laser diodes (LDs). A finite element method (FEM) was used to calculate the temperature and thermal stress distributions inside the Ho3+:BYF crystal. The damage conditions have been evaluated on the basis of the experimental results. Using 889 nm LDs with the repetition frequency and pulse duration of 13 Hz and 100 μs, respectively, an output pulse energy of 1.05 mJ at 3.9 μm for the pump pulse energy of 336.8 mJ was achieved. The study might be useful for constructing a compact and robust mid‐infrared laser.

Published: July 2021

Context. Coherence in the characteristics of neighboring sources in the 2D and 3D space may suggest the existence of large-scale cosmic structures that are useful for cosmological studies. Numerous works have been conducted to detect such features in global scales as well as in confined areas of the sky. However, their results are often contradictory and their interpretation remains controversial.
Aims. We investigate the potential alignment of parsec-scale radio jets in localized regions of the coordinate-redshift space.
Methods. We used data from the Astrogeo VLBI FITS image database to deduce jet directions of radio sources. We performed the search for statistical alignments between nearby sources and explore the impact of instrumental biases.
Results. We unveil four regions for which the alignment between jet directions deviates from randomness at a significance level of more than 5σ. We find that this effect is unlikely to be due to instrumental systematics. Intriguingly, their locations coincide with other known large-scale cosmic structures or regions of alignment.
Conclusions. If the alignments found here are the result of physical processes, the discovered regions may designate some of the largest structures known to date.
Drugs in Pregnancy and Lactation – Medications used in Swiss
Obstetrics
Authors: Schenkel Larissa , Simões-Wüst Ana Paula , Hösli Irene , von Mandach Ursula 
Published: July 2021

Abstract
Background In order to improve the safety of drugs in pregnancy and
lactation, it is imperative that data on clinical practice be collected and
validated.
Methods Data on routinely used medications were requested from 9 Swiss
perinatal centres (5 university hospitals for obstetrics and 4 non-university
centres). Furthermore, recommendations and guidelines from scientific societies
for the fields of application were sought.
Results Part II (lactation): For the lactation period, 48 different active
substances were each identified by at least 4 centres. The active constituents
most frequently cited by the centres were i. v. iron, lorazepam,
nifedipine and paracetamol. Only a few guidelines were found that explicitly
refer to the breastfeeding period. Therefore, fewer recommendations for use
during lactation could be found compared with during pregnancy.
Conclusion As with during pregnancy, the same active ingredients are
consistently used in Swiss perinatal centres for many different indications
during lactation. Most of these active ingredients are labelled with a warning
or are even considered to be contraindicated; their use is therefore mainly
off-label. Official authorisation for frequently or consistently used active
substances is urgently needed. With this study, a first important step towards
national harmonisation has been taken.
Suffrutines A and B Inhibit the Expression of Inflammatory Mediators in LPS-Induced RAW264.7 Cells by Suppressing the NF-κB Signaling Pathway

Published: July 2021

Abstract
Flueggea suffruticosa is a traditional Chinese medicine that has been commonly used for the treatment of inflammatory ailments, including rheumatism and lumbago. Suffrutines A and suffrutines B are a pair of novel E,E and Z,E isomeric indolizidine alkaloids isolated from the roots of F. suffruticosa. However, their anti-inflammatory activity has not been reported thus far. The aim of this study was to investigate the inhibitory effect of inflammatory mediators and possible mechanisms of suffrutines A and B in lipopolysaccharide-induced RAW264.7 cells. Results showed that suffrutines A and B could remarkably inhibit the production of nitric oxide, prostaglandin E2, interleukin-6, inducible nitric oxide synthase, and cyclooxygenase-2 in lipopolysaccharide-induced RAW264.7 cells. Further evaluation demonstrated that compared with suffrutines A, suffrutines B could more significantly inhibit the phosphorylation of IKKα/β, the
degradation of IκBα, and the nuclear translocation of the p65 and p52 subunits in the canonical and non-canonical nuclear factor-κB pathways. Therefore, suffrutines B exhibited more potent inhibitory activity on inflammatory mediators than suffrutines A.

AbstractObjective The aim of this study was to describe the surgical technique and outcomes of dogs with congenital thoracic vertebral body malformations (CTVBM) treated with unilateral vertebral distraction and stabilization with monocortical screws and polymethylmethacrylate (PMMA).Study Design Medical records of 10 client-owned dogs with CTVBM were retrospectively searched for signalment, history, neurological examination, neurological grade based on the modified Frankel scale (MFS), diagnostic method, CTVBM location, Cobb's angle, and vertebral canal angle (VCA), surgical procedure, complications and long-term follow-up.Results One dog suffered cardiac arrest 24 hours post-surgery and died. Median follow-up in nine dogs was 26.5 months (12–50 months). Cobb's angle improved from 33–83 to 10–46 degrees and the VCA ratio from 97–138 to 122–164 degrees. The MFS improved from 3 (n = 3)–4 (n = 7) to 4 (n = 2)–6 (n = 7). Seven dogs recovered full function. Nine dogs improved after surgery compared with preoperative status, recovering ambulation when lost or achieving normal neurological examination in seven cases. No complications were reported during the follow-up period (12–50 months).Conclusion Unilateral transthoracic vertebral distraction and stabilization with monocortical screws and PMMA for treatment of compressive myelopathy due to CTVBM achieved long-term neurological improvement in 9 of 10 dogs.

Published: July 2021

Objective This study aimed to determine clinical care practices for infants at risk for posthemorrhagic hydrocephalus (PHH) across level IV neonatal intensive care units (NICUs).
Study Design Cross-sectional survey that addressed center-specific surveillance, neurosurgical intervention, and follow-up practices within the Children's Hospitals Neonatal Consortium.
Results We had a 59% (20/34 sites) response rate, with 10 sites having at least two participants. Respondents included neonatologists (53%) and neurosurgeons (35%). Most participants stated having a standard guideline for PHH (79%). Despite this, 42% of respondents perceive inconsistencies in management. Eight same-center pairs of neonatologists and neurosurgeons were used to determine response agreement. Half of these pairs disagreed on nearly all aspects of care. The greatest agreement pertained to a willingness to adopt a consensus-based protocol.
Conclusion Practice variation in the management of infants at risk of PHH in level IV NICUs exists despite the perception that a common practice is available and used.

Translating the gay identity in audiovisual media
Authors: Pleguezuelos Antonio Jesús Martínez 
Published: July 2021

Abstract
In this study we analyse different linguistic elements in the TV series Will & Grace that
shape the gay identity of the main characters of the show. We will base the analysis on the inclusion of the cultural turn into
the field of audiovisual translation studies and on the technical time and space constraints that may emerge when conveying the
message in this type of texts. Therefore, we will focus on the treatment of cultural references associated to the LGBTQI community
that are shown on the series, as well as the linguistic variant of gayspeak and the comic elements included in the dialogues in
order to observe whether the information that viewers of the Spanish dubbed version receive regarding gay identity is the same
that is portrayed in the original version in English.
Robust identification of topological phase transition by self-supervised machine learning approach
Authors: Ho Chi-Ting , Wang Daw-Wei 
Published: July 2021

Abstract
We propose a systematic methodology to identify the topological phase transition through a self-supervised machine learning model, which is trained to correlate system parameters to the non-local observables in time-of-flight experiments of ultracold atoms. Different from the conventional supervised learning approach, where the predicted phase transition point is very sensitive to the training region and data labeling, our self-supervised learning approach identifies the phase transition point by the largest deviation of the predicted results from the known system parameters and by the highest confidence through a systematic shift of the training regions. We demonstrate the robust application of this approach results in various 1D and 2D exactly solvable models, using different input features (time-of-flight images, spatial correlation function or density–density correlation function). As a result, our self-supervised approach should be a very general and reliable method for many condensed matter or solid state systems to observe new states of matters solely based on experimental measurements, even without a priori knowledge of the phase transition models.

Abstract
Opening the silicon oxide mask of a capacitor in dynamic random access memory is a critical process on a capacitive coupled plasma (CCP) etch tool. Three steps, dielectric anti-reflective coating (DARC) etch back, silicon oxide etch and strip, are contained. To acquire good performance, such as low leakage current and high capacitance, for further fabricating capacitors, we should firstly optimize DARC etch back. We developed some experiments, focusing on etch time and chemistry, to evaluate the profile of a silicon oxide mask, DARC remain and critical dimension. The result shows that etch back time should be controlled in the range from 50 to 60 s, based on the current equipment and condition. It will make B/T ratio higher than 70% meanwhile resolve the DARC remain issue. We also found that CH2F2 flow should be ~15 sccm to avoid reversed CD trend and keep inline CD.

Published: July 2021

Abstract
In order to further reduce the cost and power consumption of smart homes, and increase the control methods of smart homes, a smart home monitoring system based on STM32 single-chip microcomputer is designed. The system uses STM32F103C8T6 as the main control chip, which collects the data information of temperature, humidity, light intensity, PM2.5 and methane concentration sent by the sensor, supplemented by a WIFI module, and uses ESP8266WIFI communication technology to transmit the data to the platform. The system test results show that when the room temperature exceeds 26 degrees, the refrigeration relay module works. When the PM2.5 concentration exceeds 150μg/m3, the fan turns on. When the methane concentration in the natural gas exceeds 1600 ppm, the buzzer alarms and the curtain relay works. System users can monitor and display home measurement data through OLED screens, Qt interface, mobile apps, and monitor and display home measurement data. Users can remotely monitor home conditions through the mobile client APP, and realize functions such as home temperature control, environmental detection, and curtain control.
Vertical software controllable system design for grid service operation process
Authors: Jinbo Zhang , Wuqiang Shen , Guiquan Shen 
Published: July 2021

Abstract
The traditional software control system with partition management is applied to the grid service operation process with more complex data structure, which will lead to slow system response due to high concurrency pressure. In view of the above problems, a vertical software controllable system is designed for the grid service operation process. After designing the hardware part of the two systems, grid server management board and communication module, the system software is designed. In the system software part, the grid service operation functional components are designed to realize the modular management of the service operation. The real-time and relational database of the system is designed, and the keyword query algorithm is used to realize the business item query to realize the system functions. The simulation experiment results show that the response time of the controllable system is all below 2000ms, which meets the demand of grid service operation, and the system has good concurrency resistance.
