Microhabitat partitioning is driven by preferences, not competition, in two Costa Rican millipede species
Authors: Cooley Shane M. , Oldfield Ronald G.
Published: September 2021

The co-occurrence of similar species in a particular environment may be facilitated if they specialise on different microhabitats, reducing competition between them. In some cases, two species prefer the same microhabitat, but one is competitively excluded to its harsh margins. In this study, we assessed microhabitat preferences and competition between two species of millipedes in Costa Rica. (1) We observed them in the wild and foundNyssodesmus pythonmost often on wood, less often on leaves, and rarely on rocks. Spirobolida was found most often on leaves, less often on wood, and never on rocks. (2) We tested their preferences in the lab and found thatN. pythonpreferred wood to rocks, wood to leaves, and rocks to leaves. Spirobolida preferred leaves to rocks, leaves to wood, and wood to rocks. (3) We tested interference competition by placing both species together in an arena in which they both had the same preference (wood vs. rocks). Both species chose to cohabitate in the same wood, indicating that one species did not directly exclude the other. InN. pythonand Spirobolida, co-occurrence is facilitated by differences in microhabitat preferences and not because competition forces one species out of its preferred microhabitat.

Published: September 2021

Background:

In this era of public scrutiny, there is an ongoing need for innovative methods for patient follow-up.

Objectives:

As part of a quality initiative, we developed an automated post-operative follow-up system for patients following discharge after cardiac surgery at Boston Children’s Hospital.

Methods:

Discharge Communication (DisCo) is a web-based system developed at Boston Children’s Hospital. An automated text and e-mail with a link to a health status survey are sent at 30 days and 1 year post-discharge in English/Spanish. If there is no response, surveys are completed via phone calls to the patient/patient’s physician or chart review. Responses are stored in the DisCo database and the patient’s medical record. Patients who underwent cardiac surgery and survived to hospital discharge from October, 2016 received the surveys.

Results:

Overall, 3345 30-day and 2563 1-year surveys were sent between October, 2016 and June, 2020. Of 3345 30-day surveys, there were 3191 responses (95%). Of 2563 1-year surveys, there were 1807 responses (71%). Most patients/families responded directly to the link at 30 days (65% for paediatrics/75% for adults) and at 1 year (72% for paediatrics/78% for adults). Multi-variable logistic regression revealed that higher complexity of cardiac lesion, presence of major non-cardiac anomalies and presence of major residua were associated with readmission and catheter/surgical reinterventions. Non-cardiac anomalies were associated with increased need for services for learning, development or behaviour.

Conclusions:

DisCo provides a successful web-based health status assessment of patients following congenital cardiac surgery. It helps to identify high-risk patients who need closer follow-up.

Published: September 2021

Objective:

The massive increase in COVID-19 cases led to the implementation of nationwide lockdown in Turkey. While enforced lockdown is an effective strategy to abate the transmission of the virus, it causes significant lifestyle changes in every part of the community. This study aims to assess the changes in eating habits, sleeping behaviour and physical activity status of final-year medical students (interns) whose education was suspended during the pandemic.

Design:

In this cross-sectional epidemiological study, an online questionnaire was created. Interns were asked questions regarding socio-demographic status, eating habits, sleeping behaviour and physical activity status before and during COVID-19 pandemic. Changes in dietary habits and sleep quality were evaluated under the guidance of Turkey Dietary Guidelines, Determination of Nutritional Status Report, Turkey National Nutrition and Health Survey and Pittsburgh Sleep Quality Index.

Setting:

Hacettepe University Faculty of Medicine – Ankara, Turkey.

Participants:

Among 536 students, a total of 340 students (63·4 %) answered the questionnaire.

Results:

After the beginning of lockdown, an increase in BMI was observed in both female (P = 0·002) and male students (P = 0·013). Students having healthy dietary habits increased by 18·8 % and unhealthy dietary habits decreased by 3·2 % during lockdown (P < 0·001). Overall, 63·2 % of students reported a decrease in physical activity, and 33·6 % reported a reduction in sleep quality, whereas 38·6 % reported an improvement in sleep quality. There was no significant difference in sleep quality between genders (P = 0·075).

Conclusions:

This study indicated that medical school suspension and enforced lockdown led to significant changes in interns’ eating behaviour, physical activity and sleeping habits.
ON SEPARABILITY FINITENESS CONDITIONS IN SEMIGROUPS
Authors: MILLER CRAIG , O’REILLY GERARD , QUICK MARTYN , RUŠKUC NIK
Published: September 2021

Taking residual finiteness as a starting point, we consider three related finiteness properties: weak subsemigroup separability, strong subsemigroup separability and complete separability. We investigate whether each of these properties is inherited by Schützenberger groups. The main result of this paper states that for a finitely generated commutative semigroupS, these three separability conditions coincide and are equivalent to every$\mathcal {H}$-class ofSbeing finite. We also provide examples to show that these properties in general differ for commutative semigroups and finitely generated semigroups. For a semigroup with finitely many$\mathcal {H}$-classes, we investigate whether it has one of these properties if and only if all its Schützenberger groups have the property.

High‐Precision Tracking of Sandstone Deformation From Micro‐CT Images

Published: September 2021

Elastic properties of sandstones can be highly pressure dependent. However, the pressure‐induced deformation of intact sandstones in X‐ray micro‐Computed Tomography (micro‐CT) images are below the resolving power of conventional image analysis methods. Also, most digital rock physics studies of the elastic properties operate with micro‐CT images acquired at ambient pressure. Here, we perform a comprehensive analysis of an intact sandstone sample with pronounced stress‐sensitivity. A purpose‐built X‐ray‐transparent pressure cell enables scanning micro‐CT images at confining pressures of up to 36 MPa. To detect the small pressure‐induced changes from these images, we design an overall deformation detection workflow with slice‐searching technique. We apply this workflow to a set of micro‐CT images of a 2 × 2 × 2 mm sample scanned at several pressures with a voxel size length of ∼1 μm. The results give the static modulus of 2.78 GPa, which is ∼0.5 times of the dynamic modulus derived from ultrasonic measurements. This ratio is consistent with literature data, showing the accuracy of the deformation detection workflow. Images scanned at different pressures are then segmented into two‐phase labels. The porosity change detected from segmented labels is consistent with the value derived from static modulus using poroelastic theory. The two‐phase segmented images are utilized to simulate the elastic properties with a finite element method. Most of the pressure dependency of elastic moduli shown in ultrasonic measurements is caused by closure of compliant pores at grain contacts, which cannot be resolved by the micro‐CT. The accuracy improvement of the estimated elastic properties from images scanned at higher pressures is negligible.
Noise-robust classification of single-shot electron spin readouts using a deep neural network

Published: September 2021

Single-shot readout of charge and spin states by charge sensors such as quantum point contacts and quantum dots are essential technologies for the operation of semiconductor spin qubits. The fidelity of the single-shot readout depends both on experimental conditions such as signal-to-noise ratio, system temperature, and numerical parameters such as threshold values. Accurate charge sensing schemes that are robust under noisy environments are indispensable for developing a scalable fault-tolerant quantum computation architecture. In this study, we present a novel single-shot readout classification method that is robust to noises using a deep neural network (DNN). Importantly, the DNN classifier is automatically configured for spin-up and spin-down traces in any noise environment by tuning the trainable parameters using the datasets of charge transition signals experimentally obtained at a charging line. Moreover, we verify that our DNN classification is robust under noisy environment in comparison to the two conventional classification methods used for charge and spin state measurements in various quantum dot experiments.

Fluorescence imaging of tumours facilitates rapid intraoperative diagnosis. Thus far, a promising activatable fluorescence probe for hepatocellular carcinoma (HCC) has not been developed. Herein, the utility of the fluorescence imaging of HCC using a β-galactosidase (β-Gal)-activatable fluorescence probe SPiDER-βGal was examined. β-Gal activity was measured in cryopreserved tissues from 68 patients. Live cell imaging of HCC cell lines and imaging of tumour-bearing model mice were performed using SPiDER-βGal. Furthermore, fluorescence imaging was performed in 27 freshly resected human HCC specimens. In cryopreserved samples, β-Gal activity was significantly higher in tumour tissues than in non-tumour tissues. Fluorescence was observed in HCC cell lines. In mouse models, tumours displayed stronger fluorescence than normal liver tissue. In freshly resected specimens, fluorescence intensity in the tumour was significantly higher than that in non-tumour liver specimens as early as 2 min after spraying. Receiver operating characteristic curves were generated to determine the diagnostic value of SPiDER-βGal 10 min after its spraying; an area under the curve of 0.864, sensitivity of 85.2%, and specificity of 74.1% were observed for SPiDER-βGal. SPiDER-βGal is useful for the rapid fluorescence imaging of HCC. Fluorescence imaging guided by SPiDER-βGal would help surgeons detect tumours rapidly and achieve complete liver resection.

The detection and removal of poor-quality data in a training set is crucial to achieve high-performing AI models. In healthcare, data can be inherently poor-quality due to uncertainty or subjectivity, but as is often the case, the requirement for data privacy restricts AI practitioners from accessing raw training data, meaning manual visual verification of private patient data is not possible. Here we describe a novel method for automated identification of poor-quality data, called Untrainable Data Cleansing. This method is shown to have numerous benefits including protection of private patient data; improvement in AI generalizability; reduction in time, cost, and data needed for training; all while offering a truer reporting of AI performance itself. Additionally, results show that Untrainable Data Cleansing could be useful as a triage tool to identify difficult clinical cases that may warrant in-depth evaluation or additional testing to support a diagnosis.

Published: September 2021

Ulnar shortening osteotomy (USO) for ulnar impaction syndrome potentially leads to degenerative changes of the distal radioulnar joint (DRUJ). This study was performed to evaluate the effect of the sigmoid notch morphology on the stress distribution pattern of the DRUJ using computed tomography (CT) osteoabsorptiometry (CT-OAM). We reviewed the pre- and postoperative transverse CT images of 15 wrists that had undergone USO. The examined wrists were classified into two groups based on the sigmoid notch morphology: the linear-type notch (type L) and the curved-type notch (type C). We calculated and statistically compared the percentage of the high-density area (%HDA) in each divided region of the sigmoid notch. In type L, %HDA was significantly larger in the distal-dorsal region of the sigmoid notch before USO. Postoperatively, in type L, no specific regions showed a significantly different %HDA. In type C, %HDA was significantly larger in the distal-volar region of the sigmoid notch before USO. Postoperatively, %HDA of type C was significantly larger in the proximal-volar region. Our results suggest that in patients with ulnar impaction syndrome, morphological evaluation of the sigmoid notch can serve as a predictor of osteoarthritis in the DRUJ with or without USO.

Published: September 2021

Prevascularized artificial three-dimensional (3D) tissues are effective biomaterials for regenerative medicine. We have previously established a scaffold-free 3D artificial vascular tissue from normal human dermal fibroblasts (NHDFs) and umbilical vein-derived endothelial cells (HUVECs) by layer-by-layer cell coating technique. In this study, we constructed an artificial vascular tissue constructed by human adipose tissue-derived stromal cells (hASCs) and HUVECs (ASCVT) by a modified technique with cryopreservation. ASCVT showed a higher thickness with more dense vascular networks than the 3D tissue based on NHDFs. Correspondingly, 3D-cultured ASCs showed higher expression of several angiogenesis-related factors, including vascular endothelial growth factor-A and hepatic growth factor, compared to that of NHDFs. Moreover, perivascular cells in ASCVT were detected by pericyte markers, suggesting the differentiation of hASCs into pericyte-like cells. Subcutaneous transplantation of ASCVTs to nude mice resulted in an engraftment with anastomosis of host’s vascular structures at 2 weeks after operation. In the engrafted tissue, the vascular network was surrounded by mural-like structure-forming hASCs, in which some parts developed to form vein-like structures at 4 weeks, suggesting the generation of functional vessel networks. These results demonstrated that cryopreserved human cells, including hASCs, could be used directly to construct the artificial transplantable tissue for regenerative medicine.

Published: September 2021

When hemoglobin (Hb) is fully saturated with oxygen, the additional gain in oxygen delivery (DO2) achieved by increasing the fraction of inspired oxygen (FiO2) is often considered clinically insignificant. In this study, we evaluated the change in DO2, interrogated by mixed venous oxygen saturation (SvO2), in response to a change in FiO2 of 0.5 during cardiac surgery. When patients were hemodynamically stable, FiO2 was alternated between 0.5 and 1.0 in on-pump cardiac surgery patients (pilot study), and between 0.3 and 0.8 in off-pump coronary artery bypass grafting patients (substudy of the CARROT trial). After the patient had stabilized, a blood gas analysis was performed to measure SvO2. The observed change in SvO2 (ΔSvO2) was compared to the expected ΔSvO2 calculated using Fick’s equation. A total 106 changes in FiO2 (two changes per patient; total 53 patients; on-pump, n = 36; off-pump, n = 17) were finally analyzed. While Hb saturation remained near 100% (on-pump, 100%; off-pump, mean [SD] = 98.1% [1.5] when FiO2 was 0.3 and 99.9% [0.2] when FiO2 was 0.8), SvO2 changed significantly as FiO2 was changed (the first and second changes in on-pump, 7.7%p [3.8] and 7.6%p [3.5], respectively; off-pump, 7.9%p [4.9] and 6.2%p [3.9]; all P < 0.001). As a total, regardless of the surgery type, the observed ΔSvO2 after the FiO2 change of 0.5 was ≥ 5%p in 82 (77.4%) changes and ≥ 10%p in 31 (29.2%) changes (mean [SD], 7.5%p [3.9]). Hb concentration was not correlated with the observed ΔSvO2 (the first changes, r =  − 0.06, P = 0.677; the second changes, r =  − 0.21, P = 0.138). The mean (SD) residual ΔSvO2 (observed − expected ΔSvO2) was 0%p (4). Residual ΔSvO2 was more than 5%p in 14 (13.2%) changes and exceeded 10%p in 2 (1.9%) changes. Residual ΔSvO2 was greater in patients with chronic kidney disease than in those without (median [IQR], 5%p [0 to 7] vs. 0%p [− 3 to 2]; P = 0.049). DO2, interrogated by SvO2, may increase to a clinically significant degree as FiO2 is increased during cardiac surgery, and the increase of SvO2 is not related to Hb concentration. SvO2 increases more than expected in patients with chronic kidney disease. Increasing FiO2 can be used to increase DO2 during cardiac surgery.
Plasticity in gustatory and nociceptive neurons controls decision making in C. elegans salt navigation

Published: September 2021

A conventional understanding of perception assigns sensory organs the role of capturing the environment. Better sensors result in more accurate encoding of stimuli, allowing for cognitive processing downstream. Here we show that plasticity in sensory neurons mediates a behavioral switch in C. elegans between attraction to NaCl in naïve animals and avoidance of NaCl in preconditioned animals, called gustatory plasticity. Ca2+ imaging in ASE and ASH NaCl sensing neurons reveals multiple cell-autonomous and distributed circuit adaptation mechanisms. A computational model quantitatively accounts for observed behaviors and reveals roles for sensory neurons in the control and modulation of motor behaviors, decision making and navigational strategy. Sensory adaptation dynamically alters the encoding of the environment. Rather than encoding the stimulus directly, therefore, we propose that these C. elegans sensors dynamically encode a context-dependent value of the stimulus. Our results demonstrate how adaptive sensory computation can directly control an animal’s behavioral state.

Published: September 2021

Conifer-feeding bark beetles are important herbivores and decomposers in forest ecosystems. These species complete their life cycle in nutritionally poor substrates and some can kill enormous numbers of trees during population outbreaks. The Eurasian spruce bark beetle (Ips typographus) can destroy >100 million m3 of spruce in a single year. We report a 236.8 Mb I. typographus genome assembly using PacBio long-read sequencing. The final phased assembly has a contig N50 of 6.65 Mb in 272 contigs and is predicted to contain 23,923 protein-coding genes. We reveal expanded gene families associated with plant cell wall degradation, including pectinases, aspartyl proteases, and glycosyl hydrolases. This genome sequence from the genus Ips provides timely resources to address questions about the evolutionary biology of the true weevils (Curculionidae), one of the most species-rich animal families. In forests of today, increasingly stressed by global warming, this draft genome may assist in developing pest control strategies to mitigate outbreaks.

Perception of Incongruent Audiovisual Speech: Distribution of Modality-Specific Responses
Authors: Sandhya  , Vinay  , V Manchaiah,
Published: September 2021

Purpose:

Multimodal sensory integration in audiovisual (AV) speech perception is a naturally occurring phenomenon. Modality-specific responses such as auditory left, auditory right, and visual responses to dichotic incongruent AV speech stimuli help in understanding AV speech processing through each input modality. It is observed that distribution of activity in the frontal motor areas involved in speech production has been shown to correlate with how subjects perceive the same syllable differently or perceive different syllables. This study investigated the distribution of modality-specific responses to dichotic incongruent AV speech stimuli by simultaneously presenting consonant–vowel (CV) syllables with different places of articulation to the participant's left and right ears and visually.

Design:

A dichotic experimental design was adopted. Six stop CV syllables /pa/, /ta/, /ka/, /ba/, /da/, and /ga/ were assembled to create dichotic incongruent AV speech material. Participants included 40 native speakers of Norwegian (20 women,Mage= 22.6 years,SD= 2.43 years; 20 men,Mage= 23.7 years,SD= 2.08 years).

Results:

Findings of this study showed that, under dichotic listening conditions, velar CV syllables resulted in the highest scores in the respective ears, and this might be explained by stimulus dominance of velar consonants, as shown in previous studies. However, this study, with dichotic auditory stimuli accompanied by an incongruent video segment, demonstrated that the presentation of a visually distinct video segment possibly draws attention to the video segment in some participants, thereby reducing the overall recognition of the dominant syllable. Furthermore, the findings here suggest the possibility of lesser response times to incongruent AV stimuli in females compared with males.

Conclusion:

The identification of the left audio, right audio, and visual segments in dichotic incongruent AV stimuli depends on place of articulation, stimulus dominance, and voice onset time of the CV syllables.
Motivation, Rapport, and Resilience: Three Pillars of Adolescent Therapy to Shift the Focus to Adulthood
Authors: Abendroth Kathleen J. , Whited Jennifer E.
Published: September 2021

Purpose

The purpose of this clinical focus article is to encourage speech-language pathologists (SLPs) to shift their operational framework as students grow from childhood to adulthood by focusing on three pillars of interaction: motivation, rapport, and resilience. We need to foster greater independence and interpersonal skills in older students, but researchers have not explained how to help SLPs successfully transition their intervention strategies. Here, we identify three pillars of adolescent therapy—motivation, rapport, and resilience—to help clinicians shift their perspective from childhood to adulthood. We rely on social constructivism to guide practice and argue that client-centered models of therapy are more appropriate than therapist-centered models for adolescent students. For each pillar, we discuss clinician behaviors, student results, and clinical implications.

Conclusions

By strengthening these three pillars of interaction, clinicians can shift their focus toward client-centered therapy models and facilitate skills students need in adulthood. Strengthening skills related to motivation, rapport, and resilience will help support more symmetrical and flexible clinical partnerships in adolescent students with communication disorders.

Published: September 2021

In face of increasingly severe environmental problems, green and low-carbon power supply has become an important trend of current development. At present, the smart grid which will respond to the demand has improved the interaction between current users and the grid. In addition, electric heating and solar power generation and other renewable power generation methods are promoted in north China. Electric heating is a flexible and regulatable load; when it reaches a certain scale, it is bound to become an objective demand response resource in power grid operation, so it is of great practical significance to explore the evaluation of the regulation capacity of electric heating load.

Does Farmland Size Affect the Collective Action in Rural Areas? An Empirical Study on the Public Irrigation System in China
Authors: Zang Liangzhen , Su Yiqing
Published: September 2021

Since smallholders accounted for a high proportion of 98.1% among the 207 million agricultural business households across China, it is particularly important to study the impact of farmland size on the provision of public goods attached to the public sector industries from the perspective of the irrigation collective action in rural areas. Based on the survey data of 283 villages in China, this paper finds that the farmland size has a positive impact on irrigation collective action, although the average of per capita farmland area is only 0.214 hectares in each household of China. Therefore, it is necessary to promote the farmland scale operation by land circulation, so as to improve the ability of collective action and the development of public sector industries in rural areas of China.

Published: September 2021

With the rapid rise of social network sites, people’s life and work are influenced to varying degrees. And this paper aims to explore how does social network sites use(SNSU) affect employee well-being(EWB) and the mediating effects of body image disturbance(BID) and self-esteem(SE). Social network sites use, employee well-being, body image disturbance and self-esteem scales were used to obtain data of 435 employees. Results showed that social network sites use positively predicted employee well-being; Self-esteem played a mediating role in the relationship between social network sites use and employee well-being, but the mediation of body image disturbance and the chain mediation of body image disturbance and self-esteem weren’t significant. So social network sites use can lead to body image disturbance to some extent but overall, its impact was positive, which was contributing to employee well-being.

Research on the Relationship between Trade Volatility, Property Rights and New Energy Stock Returns under the Background of New Energy Industry Development
Authors: Peng Qiyuan
Published: September 2021

The research on the relationship between risk and return of new energy stocks is the focus of financial research. Related research focuses more on the relationship between idiosyncratic fluctuation risk and stock returns. In the Chinese stock market, some Chinese investors clearly prefer stocks with high risk characteristics, which leads to overvalued stocks. However, the short-selling restrictions in the Chinese stock market and the heterogeneity of investors have also led to a significant negative correlation between idiosyncratic volatility and cross-sectional yield. There are many studies on the relationship between idiosyncratic volatility and stock returns, but no consistent conclusions have been drawn, and there is a lack of relevant research on new energy stocks. Therefore. This paper collates the data of 70 listed companies in the new energy and new energy automobile industry from 2017 to 2019, tracks the stock returns of sample companies for 3 years (36 months), and conducts in-depth research on the relationship between idiosyncratic fluctuation risks and new energy stock returns. To further verify and supplement the risk-return relationship of China's new energy stock market and provide a certain basis for the company's decision-making behaviour.

Published: September 2021

For some companies, sales means arranging goods and selling them on the shelves. This kind of arrangement of goods regardless of priority brings a lot of internal consumption to the enterprise. With the rapid development of the Internet and industry, many large companies have gradually established and improved their production and sales processes. The traditional ABC classification method can no longer meet this demand. The new method that can compensate for the traditional ABC classification method is particularly important. This article uses association rules to use the ABC classification method to study the expected budget of commodities, uses the Apriori and FP-Growth algorithms in the association rules to collect frequent itemsets of the acquired data, calculates the corresponding association rules, and then classifies the commodities with ABC.

The transaction cost analysis and future development of the “blockchain + audit” industry—— based on the analytic hierarchy model and the perspective of industry life cycle
Authors: Tian Wenzhong
Published: September 2021

The rise of “blockchain +” has a great impact on all fields and even the whole social and economic situation, and is no exception to the audit work. Blockchain has the characteristics of non-tampering, timestamp, grid consensus and so on, which is in line with the requirements of the audit work to pursue efficiency and effect. Under such a development background, the “blockchain+audit” industry arises from this. The integration of blockchain into audit engagements, in turn, changes the proportion of audit transaction costs. Based on this background, the Analytic Hierarchy Process (AHP) is used to analyze the transaction cost of audit. In view of the problems found in the current transaction cost analysis of “blockchain+audit”, combined with the research on the future development trend based on the theory of technological innovation and industry life cycle, this paper puts forward some suggestions to effectively control the audit cost and improve the audit efficiency. The aim is to provide a practical reference basis for the better application of blockchain technology in auditing.
