Eco-Friendly and Solar light Active Ti-Fe2O3 Ellipsoidal Capsules Nanostructure for Removal of Herbicides and Organic Dyes
Authors: Mohamed Hanan , Besisa Dina H.
Published: March 2022

In this work, Ti doped Fe2O3 with hollow ellipsoidal capsules nanostructure has been prepared in a green manner using plant extract (Flax seed). This new green hematite nanomaterial has been evaluated as photocatalyst for water treatment by testing its activity for degradation of bromophenol blue dye (BPB) and 2,4-dichlorophenoxy acetic acid (2,4-D) herbicide. For a better understanding of the green material properties, a comparison with the pristine Fe2O3 nanospheres previously prepared by the same procedure is included. Structural and optical properties of the green prepared materials are studied. The results revealed the success doping of Ti4+ at Fe3+ site, without forming any of TiO2 phases. It was also found that, the Ti doping is resulted in the reduction of the band gap of Fe2O3 as well as changing the morphology. The Ti-doped Fe2O3 nanomaterial exhibited an enhanced photocatalytic activity either for BPB dye or for 2,4-D degradation with more than 2 times higher rate than that using pristine Fe2O3.

Authors: Tian Ya , Ma Liwen , Xi Xiaoli , Nie Zuoren
Published: March 2022

At present, alloy materials have been widely used as wear-resistant coatings due to good mechanical properties. In this paper, electrodeposition was used to prepare the Co-Mo coating. The electrochemical behavior of the deposition of alloy and the phase composition, morphology, composition and property of the coating have been studied. The study of process parameters found that when the concentration of Na2Mo4 is 0.05mol/L, the concentration of C6H5Na3O7 is 0.15mol/L, the pH of the solution is 7, and the temperature is 50℃, the content of Mo in Co-Mo coating is 39.56%, and the microhardness reaches the maximum value of 503HV. The study of electrochemical behavior found that when the concentration of Na2Mo4 is 0.05mol/L, the concentration of C6H5Na3O7 is 0.15mol/L, the pH of the solution is 7 and the temperature is 50℃, the most positive deposition potential, maximum exchange current density and minimum charge transfer impedance were obtained, which explained why the best performance coating can be obtained under this condition.

Objective
This study aimed to qualitatively assess and compare some techniques involved in cuff inflation and its corresponding pressure estimations as well as associated complications among patient s undergoing general anaesthesia with intubation for cesarean section at the obstetric unit of the Tamale Teaching Hospital.
Results
Finger palpation of the pilot balloon, predetermined volume of air, and a pressure gauge were used to measure endotracheal tube cuff pressure after intubation . Associated side effects were determined after 24 hours of endotracheal tube extubation. Data for 384 patients were included in the analysis. Cuff pressure measured among patients varied from < 20 -30 cmH 2 O for the standard manometer group, 20 to 50 cmH 2 O for the predetermined volume of air group and < 20 to < 50 cmH 2 O for the finger palpation group. Side effects were recorded in 2.3 % of patients from the standard manometer group, 53.2 % from the predetermined volume of air group and 83.6 % from the finger palpation group. The findings of this study, therefore, suggested that finger palpation of a pilot balloon and a predetermined volume of air methods are prone to cuff over inflation and post-extubation airway complications.

Published: March 2022

Background: The human papillomavirus (HPV) is one of the most widespread viruses on the planet. A previous study found that HPV prevalence has an age-related relationship. Multiple HPV infections have a bad outcome. HPV infection is linked to uterine cervical cancer, bacterial vaginitis, cervicitis, fungal vaginitis, and pelvic inflammation, among other gynecological conditions. Furthermore, HPV infection during pregnancy has a negative impact on the health of both the mother and the fetus. In Chinese women, the prevalence of HPV and the link between HPV infection and various diseases are still unknown.Methods: A Genotyping Test Kit was used to determine individual HPV genotypes (Life River Co., Shanghai, China). The prevalence of HPV types and ages was collected and analyzed by using SPSS 22.0 software.Results: The HPV infection positive rate was 20.3% overall, including HPV single genotype (74.3%), HPV double genotype (18.4%), and HPV triple infections (7.4%). The top fifth prevalent HPV genotypes were HPV52 (25.5% of the positive individuals), HPV16 (19.7%), HPV58 (21.7%), HPV51 (11.4%) and HPV39 (9.6%). The <20-year old group represented highest HPV infection rate, and HPV infection rates rise with age, especially multiple HPV infection rates. There were significant differences for fungal vaginitis (P=0.010; χ2=6.61) and cervical lesions (P=0.000; χ2=1069.60) with the health check group. The prevalence of HPV infection is significant popular among fungal vaginitis (P=0.010; χ2=6.61) and cervical lesions (P=0.000; χ2=1069.60). The early pregnant women, middle-late pregnant women HPV positive ration was lower than routine health checks HPV infection rates. hpv52: hpv58 enjoy the highest infection rate among the multiple HPV combination.Conclusion: HPV infection was serious among women in China. HPV infection is linked to one's age in Chinese. Women under the age of 20 have the highest HPV prevalence, implying that HPV vaccination is required for young people. Multiple HPV infections have a cumulative effect as people become older. It's possible that HPV infection is linked to vaginitis since vaginitis makes you more susceptible to infection. HPV infections in pregnant women are common and require additional care.
A strategic analysis of incorporating corporate environmental responsibility into managerial incentive design: A differential game approach
Authors: Teng Minmin , Zhao Meiting , Han Chuanfeng , Liu Pihui
Published: March 2022

As corporations’ environmental impacts come under greater scrutiny by global financial, regulatory and societal stakeholders, management scholars have increasingly focused on the role corporate governance plays in undertaking corporate environmental responsibility (CER). This paper combines managerial incentives and CER in a dynamic environment to formulate a differential game model of managerial incentive design in a duopolistic market, investigating whether companies with maximum interests are motivated to provide their professional managers with incentives related to CER and the impact of such incentives on corporate profitability, social welfare and emissions reduction. The results demonstrate that (1) employing professional managers will increase the emissions reduction efforts of firms and giving incentives to professional managers will further increase the emissions reduction level of firms. (2) When a firm employs a professional manager and pays a fixed salary, profit is slightly lower than when a manager is not employed but, if a professional manager is given CER-related incentives, profit will be greatly increased. (3) As long as professional managers are employed, social welfare will increase regardless of whether professional managers are given incentivized pay. Total social welfare is the lowest in a duopolistic market when neither firm employs a professional manager, and social welfare is the highest when both employ a professional manager and give CER-related incentives. (4) The emissions reduction of a firm increases with an increase in the income distribution coefficient π1.

Treatment of advanced liver cancer still faces great challenges. Identification of tumor dependencies is important for developing novel therapeutic strategies for liver cancer. Here, we identified mitochondrial translation as a major vulnerability of liver cancer by genome-wide CRISPR screen. Targeting mitochondrial translation by tigecycline showed therapeutic potential in liver cancer. Then, a compounds screen was applied to identify MEK inhibitors as synergistic drugs to tigecycline-insensitive liver cancer cells. Mechanistically, sustained activation of EGFR-ERK1/2-MYC cascade conferred the insensitivity to tigecycline, which was mediated by enhanced secretion of EREG and AREG. Moreover, glycolytic enzymes, such as HK2 and PKM2, and mitochondrial one-carbon enzyme SHMT2 were upregulated to stimulate glycolysis and maintain mitochondrial function, respectively, in a MYC-dependent manner. Tigecycline in combination with MEK inhibitor trametinib or EGFR inhibitor gefitinib showed synergistic antitumor effect in vitro and in vivo. Thus, our study provides a potential therapeutic strategy for liver cancer.

Published: March 2022

(Background) Dupilumab, an anti-IL-4α receptor antibody, is a new treatment for severe or refractory asthma, but real-world evidence is lacking for the efficacy of dupilumab in patients with mild to moderate bronchial asthma.(Methods) We retrospectively evaluated the effect of dupilumab in 62 patients received with dupilumab for eosinophilic sinusitis comorbid with asthma at a single center in Japan. Type 2 inflammatory markers, ACT, respiratory function tests, and forced oscillation technique (FOT) were analyzed before, three months after, and one year after dupilumab administration, mainly in patients with mild to moderate asthma.(Results) FEV1, %FEV1, %FVC, treatment step for asthma and ACT improved significantly after three months of dupilumab treatment. FeNO was markedly decreased, whereas IgE and eosinophil counts showed no significant changes. Pre and post-treatment respiratory resistance (Rrs) and respiratory reactance (Xrs) correlated significantly with FEV1. Improvement in %FEV1 was associated with higher FeNO and higher serum IgE before dupilumab treatment.(Conclusion) Dupilumab treatment for sinusitis may benefit respiratory function, asthma symptoms, and asthma treatment reduction, even if the associated bronchial asthma is not severe.

Background The effect of strabismus surgery on the quality of life of strabismus patients with thyroid-associated ophthalmopathy is unclear, The aim of the study is to explore the effect of strabismus surgery on the quality of life of strabismus patients with quiescent thyroid-associated ophthalmopathy (TAO).Methods This study is a prospective case-series study. Strabismus patients with TAO who were admitted in the First Affiliated Hospital of Guangxi Medical University from October 2011 to April 2016 were included in this study. The patients completed the Graves' ophthalmopathy quality of life questionnaire (GO-QOL) before the operation and 6 weeks after the operation. Preoperative and postoperative quality of GO-QOL scores were compared using paired samples t-test. The correlation between the angle of misalignment and the quality of life was analyzed using Spearman correlation analysis.Results We recruited 23 patients for this study, including 11 males and 12 females. Patients were 31-67 years old with a mean age of 49.04 years. Compared to preoperative GO-QOL scores, postoperative GO-QOL scores for visual function (43.04 vs. 73.50, p<0.001) and psychosocial function (40.13 vs. 72.93, p<0.001 ) were significantly increased, respectively. The greater the preoperative angle of misalignment was, the worse the psychosocial function (r= -0.433, p=0.039).Conclusions Strabismus surgery significantly improves the quality of life of the strabismus patients with quiescent TAO.

Published: March 2022

Considering memory occupation and large amount of operation of the conventional coal mine roadway 3D point cloud information map modeling method, studied the roadheader cutting error detection and compensation control system based on 3D laser scanning. A driving roadway space modeling method based on point cloud data and 3D grid mapping is proposed. the roadway space is divided into limited grids to form a three-dimensional raster map of roadway space, and 3D grid is divided into multiple functional areas. Through the conversion between 3D lidar coordinate system and roadway coordinate system, the point cloud data measured by 3D lidar can be converted into roadway contour data. Cutting error compensation control model is established to realize the compensation control of roadheader cutting underexcavation. Through the experimental verification, when three-dimensional grid side length size is set to 10cm, raster map obtained by the cutting forming roadway 3D raster map modeling method in this paper is used to guide the operation of the roadheader cutting system, which can reduce the data processing capacity by 84.7% compared with the conventional point cloud map. It is verified that the method can be used to compensate and cut the underexcavated surrounding rock of the roadway.

Recently, the trend of many studies to replace synthetic antifungals commonly used during storage with natural antifungals; Plants extracts are one of the promising strategies for this purpose. Therefore, this study aimed to evaluate the aqueous extract of carob pulp (AECP) at 1.5, 2.5, and 5mg/ml on the growth of some toxigenic Aspergillus species, and its effectiveness as antimycotoxigenic (aflatoxins and ochratoxin A) during storage red peanut kernels (RPKs) for 90 days. AECP at 5 mg/ml affected inhibition growth, as Aspergillus ochraceus was the most affected, then A. aflatoxiformans recorded (15.7 ± 0.4) and (13.4 ± 0.5), respectively. Whereas study influence of AECP on the accumulation of total AFs and OTA produced by A. parasiticus and A. ochraceus during the storage of RPKs for 90 days. The results reflected that the active compounds in the AECP can protect RPKs for 45 days without detecting any amounts of total AFs and OTA at 5mg/ml. While after 90 days, the percentages of inhibition for the four types (AFB1, AFG1, AFB2, AFG2) and OTA after storage for 90 days compared with positive control samples (85.1, 76.5, 86.5,84.2, and 87.5%), respectively. Finally, AFB1 recorded the lowest inhibition percentages with all treatments; on the contrary, it was OTA.

Published: March 2022

In order to make full use of crop waste stalk, corn-stalk cellulose (CSC) was extracted by acid-base method and used as modifier of epoxy resin (E51) to prepare the self-extracted corn-stalk cellulose / epoxy resin composites (CSCEC). Thermogravimetry (TG) analysis, dynamic mechanical analysis (DMA), morphology analysis by scanning electron microscope (SEM), the mechanical properties by electronic universal testing machine and impact testing machine were used for characterization and analysis. The experimental results showed that when the CSC content was 20 wt%, the impact strength of the composite was 2.50 kJ /m2, which was 127.2% higher than that of pure epoxy resin. Meanwhile, the tensile and bending strength were slightly increased, and the storage modulus (E') of epoxy resin was also slightly increased, indicating that the addition of CSC could toughen the epoxy resin. When the CSC content was 20 wt%, the Tg of epoxy resin obtained by DMA was the lowest, 167.4 ℃, which decreased by 11.3 ℃ compared with that of pure epoxy resin.

The bis (tetra-ethylammonium) tetraiodo-zincate (II) was prepared by slowly evaporating an aqueous stoichiometric mixture of tetra-ethylammonium iodide and zinc iodide at room temperature. X-ray diffraction (XRD), thermal analysis, UV-vis spectroscopy and complex impedance spectroscopy were used to fully characterize this compound. Single-crystal X-ray diffraction analysis indicates that the compound crystallizes at room temperature in the tetragonal system, space group P \(\stackrel{-}{4}\)21m(No.113), with lattice parameters a = 13.794 (2) Å and c = 14.900 (3) Å. Differential thermal analysis (DTA) and temperature-controlled X-ray diffraction study revealed a reversible first order phase transition at about 444 K between low and high temperature forms of [(C2H5)4N]2ZnI4. Below 444 K, the low temperature form exhibits two linear regimes of thermal expansion with a change at around 373Kascribed to a second-order phase transition. The diffuse reflectance indicates the existence of optical direct allowed transition mechanisms with the band gap energy equal to 3.9 eV.Complex impedance spectra recorded in the temperature range of 403 to 468 K were satisfactorily modelled by acombination of R//CPE elements assigned tothe electrical response of grains at the first order phase transition at around 444 K, a change of conduction regime is noted in the temperature dependence of DC-conductivity. In both regimes, the conductivity obeys the Arrhenius law with activation energies of 1.37 eV in regime I and 2.37 eVin regime II.The frequency dependent AC-conductivity followed the universal Jonscher’s power law.
To study the scope of drone usage for disaster management in India with respect to the USA with a comparison of economic factors including the GDP, the level of unemployment and inflation, and the government regulations.

The use of unmanned aerial vehicles (UAVs), also called drones, is growing rapidly across many domains, including disaster management. Developed countries like the USA have been increasingly investing in their drone technology to reap maximum benefits in the future. Since the usage of UAVs is the next big revolution, developing countries like India have also started to map the potential of this industry. The Indian government has cautiously started to use drones to combat natural disasters like cyclones and provide after-relief services on multiple occasions. Both the US and India experience countless natural calamities each year given their geographic conditions. While the US has moved towards extensive drone usage to combat these disasters, India is still struggling with its drone industry. Given the stage of the economy and the post-pandemic recovery, it is necessary to study the extent to which India can invest in drone technology when compared to the US on the basis of its economy. Moreover, besides the economy, the government regulations largely govern the functioning of an industry in a given country; on one side, where the US has extensively promoted the use of drones and eased the regulations, India still follows a slightly rigid approach to it. Hence, studying the future of these regulations and the Indian economy in general with one of the leading economies, i.e. the US, in consideration would help us to get a better understanding of both - the future of the drone industry in India and the scope of its growth in terms of disaster management.
Isoetid mediated radial oxygen loss prevents iron reduction and the related mobilisation of ammonium and methane: an experimental approach.

Published: March 2022

Isoetids are slow growing ecosystem-engineers that maintain an oligotrophic environment through high radial oxygen losses (ROL) from their roots, which could potentially reduce methane (CH4) emission by promoting CH4 oxidation. Isoetid vegetations have declined in many European countries as an effect of eutrophication and inorganic carbon enrichment. To assess the effect of sudden disappearance of isoetids on biogeochemical carbon and nutrient cycling in organically rich sediments, we set up a greenhouse experiment. Intact vegetated sediment patches with Lobelia dortmanna and Litorella uniflora were collected from ten boreal Norwegian softwater lakes. For half of the patches, isoetids were manually removed. We determined the effect of removal on sediment redox potential, nitrogen (N), phosphorus (P), inorganic carbon availability and CH4 emission. In addition, germination success of L. dortmanna seeds was tested on the sediments where isoetids were removed. The absence of ROL after isoetid removal led to a drop in sediment redox potential, resulting in anaerobic breakdown of organic matter using alternative electron acceptors, especially iron oxides. Consequently, increased pore water concentrations of ammonium (NH4+), P and CH4 were observed in sediments where isoetids had been removed compared to the isoetid vegetated sediments. Moreover, over 60 times higher emission of CH4 was observed from the sediments where isoetids had been removed. On the highly reduced sediments, the germination of L. dortmanna was hampered. When isoetids are unable to recolonize after disturbance events, it is expected that the absence of ROL eventually results in a longterm inrease in lake productivity and CH4 emission.
Passivity or Participation? A qualitative evidence synthesis for streaming clinically low acuity patients presenting in an acute care setting

Published: March 2022

Introduction: Streaming low-acuity patients to alternative services is a common strategy with the aim to reduce pressure on ED. Objective: To examine qualitative research regarding patient experience and perspectives of streaming-style interventions aimed at patients deemed clinically low-acuity. Methods: A qualitative evidence synthesis following the SPICE protocol. Findings: There are few qualitative articles exploring patient experiences of streaming. However, patient-centric streaming or navigation services emerge as a mark of quality that may conceivably support patients to gain timely and appropriate access to care.

Published: March 2022

The coexistence of two primary tumors is very rare. Additionally, hepatocellular carcinoma (HCC) and renal cell carcinoma (RCC) are even less frequent.An 81-year-old male patient had HCC and RCC synchronously. Surgery was performed primarily, as both tumors were suitable for resection. Adverse effects were observed during the patient's follow-up with adjuvant chemotherapy, and the treatment regimen was changed.This report presents the seventh case describing the treatment of synchronous double cancers of HCC and RCC. Although this rare condition shortens the patient’s life expectancy, our patient is alive even though he has a liver recurrence in the third month and is followed up to the 20th month.

Published: March 2022

Background: British Columbia has been in a state of public health emergency since 2016, due to the unprecedented numbers of overdoses and overdose deaths. Methamphetamine (MA) detection in illicit drug toxicity deaths increased from 14% in 2012 to 43% in 2020 suggesting a concerning trend of concurrent MA and opioid use in BC that reflects rising patterns identified across North America. People who use MA concurrently with opioids face an elevated risk of harm. This study aimed to identify behaviours of people who concurrently use MA and opioids practice to be safe.Methods: One-on-one semi-structured interviews were conducted by Peer Research Assistants in person and by telephone. Each interview lasted approximately 30-90 minutes and were recorded and later transcribed. Thematic analysis was carried out to identify patterns in the behaviours participants described as important to their safety in the context of concurrently using MA and opioidsResults: Participants (n=22) were distributed across the province with at least four participants from each of the five geographic health regions; 64% self-identified as men, and 50% self-identified as Indigenous. Daily MA use was reported by 72.7% of participants, and 67.3% reported using alone either often or always. From the data, we identified that participants made several considerations and adaptations in order to balance the perceived benefits and risks of their use of MA with opioids. Two overarching themes were identified to describe how participants adapted their use for survival and wellness: 1) Personal safety behaviours, and 2) interpersonal safety behaviours.Conclusions: This manuscript identified diversity in participants’ MA and opioid use (i.e. frequency, route of administration), and a subsequent range of behaviours that were performed to improve wellness and survival while using MA and opioids. Some of participants’ behaviours were practiced individually, while others relied peer support, or public health service provision. Participants identified many gaps in available services to meet their diverse needs. Harm reduction and treatment responses must be robust and adaptable to respond to the diversity of patterns of substance use among people who use opioids and MA concurrently, so as to not perpetuate harm and leave people behind.
Spatial relationships between fishes and amphibians: implications for conservation planning in a Neotropical Hotspot
Authors: Covre Amanda C. , Lourenço-de-Moraes Ricardo , Campos Felipe S. , Benedito Evanilde
Published: March 2022

Context: Species distribution patterns are widely used to guide conservation planning and are a central issue in ecology. The usefulness of spatial correlation analysis has been highlighted in several ecological applications so far. However, spatial assumptions in ecology are highly scale-dependent, in which geographical relationships between species diversity and distributions can have different conservation concerns. Objectives: An integrative landscape planning was designed to show the spatial distribution patterns of taxonomic and functional diversity of amphibians and fishes, from multiple species traits regarding morphology, life history, and behavior. Methods: We used spatial, morphological, and ecological data of amphibians and fishes to calculated the functional diversity and the spatial correlation of species.Results: Mapping results show that the higher taxonomic and functional diversity of fishes are concentrated in the West Atlantic Forest. Considering amphibians, they are located in the East portion of the biome. Spatial correlation of species indicates the regions of the Serra do Mar and the southern part of the Central Corridor as the main overlapped species distribution areas between both groups.Conclusions: New key conservation sites were reported within the Brazilian Atlantic Forest hotspot, revealing cross-taxon mismatches between terrestrial and freshwater ecosystems. This study offers useful spatial information integrating suitable habitats of fishes and amphibians to complement existing and future research based on terrestrial and freshwater conservation. New priorities for biodiversity conservation in rich-species regions highlight the importance of spatial pattern analysis to support land-use planning in a macroecological context.

Kernel-based iVAT with adaptive cluster extraction
Authors: Zhang Baojie , Zhu Ye , Rajasegarar Sutharshan , Li Gang , Liu Gang
Published: March 2022

Visual Assessment of cluster Tendency (VAT) is a popular method that visually represents the possible clusters found in a data set as dark blocks along the diagonal of a Reordered Dissimilarity Image (RDI). Although many variants of the VAT algorithm have been proposed to improve the visualisation quality on different types of datasets, they still suffer from the challenge of extracting clusters with varied densities. In this paper, we focus on overcoming this drawback of VAT algorithms by incorporating kernel methods, and also propose a novel adaptive cluster extraction strategy, named CER, to effectively identify the local clusters from the RDI. We examine their effects on an improved VAT method (iVAT), and systematically evaluate the clustering performance on 18 synthetic and real-world datasets. The experimental results reveal that the recently proposed data-dependent dissimilarity measure, namely, the Isolation kernel, helps to significantly improve the RDI image for easy cluster identification. Furthermore, the proposed cluster extraction method, CER, outperforms other existing methods on most of the datasets in terms of a series of dissimilarity measures.

Published: March 2022

Introduction: A small number of studies have shown that scabies causes impairment in the quality of life in adult patients. There was no study evaluated the depression and anxiety and their relationships between life quality in patients with scabies. The aims of this study are to assess the impact of scabies on adult patients’ quality of life and evaluate the relationship between depression and anxiety levels and impairment in life quality. Methods: This cross-sectional study included adult patients diagnosed with scabies in our dermatology outpatient clinic. The demographic data and characteristics of patients were recorded. The effect of scabies on quality of life was evaluated by Dermatology Life Quality Index (DLQI), and the levels of depression and anxiety were evaluated by Beck Depression Scale (BDS) and Beck Anxiety Scale (BAS).Results: Totally, 85 patients included to the study. The mean ± SD total DLQI score was 10.54 ± 6.17. The quality of life of 72.2% of the patients was moderate to extremely large affected. The domain with the highest impact on patients that ‘symptoms and feelings’ was impaired in all patients. The other domains that had the most impact on patients were ‘work and school’, ‘personal relationships’ and ‘daily activities’, respectively. There was a positive correlation between the duration of the disease, the total DLQI score and the severity of the disease’s impact on quality of life (rs= 0.287, p= 0.01 and rs=0.280, p= 0.008, respectively). The mean BDS score ± SD was 12.11 ± 9.52 and the mean BAS score ± SD was 8.81 ± 9.45. There was a positive correlation between BDS and BAS, and total DLQI score (rs=0.448 and p=0.000; rs=0.456 and p=0.000, respectively).Conclusion: Scabies has a moderate to severe effect on life quality on patients. There was a positive correlation between impairment quality of life and anxiety and depression scores.
Compact modelling of nanocluster functionality as a higher order neuron.
Authors: Lawrence Celestine
Published: March 2022

Disordered nanoclusters with multi-electrode input-output functionality had recently been experimentally realized with energy-efficient and emergent computational capacity, and thus an interconnected network of several such nanoclusters had been proposed to realize artificial neural networks. To aid that end, here we show that nanocluster functionality can be fit to the simplest dendritic neuron model, where the only form of nonlinearity is due to multiplicative interactions. This work brings in to the spotlight higher order neural networks (known for their efficient encoding of geometric invariances) to serve as an explainable baseline model of nano-networks against which experimentalists can compare more sophisticated models; and provides ground for designing novel approximate hardware and a statistical mechanics analysis of the learning performance of interconnected nanoclusters vs. conventional (i.e. ramp or sigmoidal activation of a weighted sum) neural networks.

China is constructing sponge cities, with focus on green roofs to counter increasing incidences of urban flooding. However, very few studies have investigated the performance of green roofs in real urban environments. Here, the Storm Water Management Model was used to simulate changes in surface runoff with green roofs while analyzing the impact of green roofs on urban flooding in Kunming, Beichen District, China. Comprehensive evaluations using the technique for order preference by similarity to an ideal solution (TOPSIS) were performed—from cost and benefit perspectives—to provide a research basis for green roof construction in Kunming. This study revealed the following: (1) higher rainfall intensity led to lesser runoff reduction. For rainfall recurrence intervals of 1, 2, 5, and 10 y, the runoff reduction rate for a green roof coverage of 10 % was 2.7, 2.1, 1.6, and 1.4 %, respectively. (2) The peak flow decreased with increasing coverage rate. However, under heavy rainfall, low coverage rates did not significantly reduce the peak flow. The delay time of the peak flow significantly decreased with increasing rainfall intensity. (3) The number of ponding points and the longest ponding duration exhibited a gradual downward trend with increasing green roof coverage. Green roofs with low coverage played an optimal role in mitigating flooding under heavy rainfall conditions. (4) Entropy weight-TOPSIS revealed that the optimal green roof coverage area in the study area was 60 %, which can be used as the priority construction goal for the popularization of green roofs in Kunming.

Recently, Generative Adversarial Networks (GANs) trained on samples of traditionally simulated collider events have been proposed as a way of generating larger simulated datasets at a reduced computational cost. In this paper we point out that data generated by a GAN cannot statistically be better than the data it was trained on, and critically examine the applicability of GANs in various situations, including a) for replacing the entire Monte Carlo pipeline or parts of it, and b) to produce datasets for usage in highly sensitive analyses or sub-optimal ones. We present our arguments using information theoretic demonstrations, a toy example, as well as in the form of a formal statement, and identify some potential valid uses of GANs in collider simulations.

Topoisomerase IIα (TOPIIα) plays a key role in DNA replication and is a molecular target for TOPIIα inhibitor chemotherapy. A doxorubicin-based chemotherapy remains the most effective treatment for canine lymphoma, but there are no clear indications for its use in individual patients. The aim of this study was to assess the predictive value of TOPIIα expression in the treatment of canine lymphomas with TOPIIα inhibitors. Samples of formalin-fixed paraffin-embedded lymph nodes from 14 dogs with diffuse large B-cell lymphoma (DLBCL) and 5 dogs with peripheral T-cell lymphoma (PTCL) treated with a CHOP protocol were immunohistochemically labelled with anti-TOPIIα. Progression-free survival time (PFS) and overall survival time (OS) were estimated and compared with TOPIIα expression. Dogs with DLBCL had a higher level of TOPIIα expression compared to dogs with PTCL. The median PFS for dogs with DLBCL was significantly longer (260 days) than it was for dogs with PTCL (60 days). In DLBCL dogs with a high TOPIIα expression level, the median PFS was significantly longer (310 days) then it was in dogs with week or medium TOPIIα expression (51 days). The results of the study indicate that the immunohistochemical assessment of TOPIIα expression may be a valuable predictive indicator for anthracycline-based treatment of dogs with malignant lymphoma.
Evaluating the effects of alternative model structures on dynamic storage simulation in heterogeneous boreal catchments

Estimating dynamic storage as a metric can be used to make an overall assessment of catchment resilience to extreme weather events such as droughts and floods. Because of the complexity of direct empirical measurements, bucket-type hydrological models can be a suitable tool to simulate the catchment storage across a broad range of scales as they require minimal input data. However, these models consist of one or more conceptual structures based on several linear or nonlinear reservoirs and connections between these reservoirs. Therefore, choosing the most appropriate model structure to represent storage-discharge functioning in catchments is difficult. To bridge this gap, this study evaluated the performance of three different HBV model structures on 14 heterogeneous boreal catchments classified into four distinct catchment categories. The results showed that the three-bucket structure performed better in larger catchments with deeper sediment soils. In contrast, a single reservoir structure is sufficient to predict the storage-discharge behavior for a lake-influenced catchment with lower elevation above the stream network. Moreover, our results indicate that while the estimates of mean catchment storage varied between the different model structures, the ranking between the catchments largely agreed for the different structures. Hence, our results suggest that instead of a single model structure, using an ensemble averaging approach would not only better address the structural uncertainty but also facilitate further storage comparison between different catchments. Finally, based on Spearman rank correlation results, we found that catchment size and sediment soil were positively correlated with dynamic storage estimation.

The objective of this study was to understand the drinking water quality state in the Inner Mongolia Autonomous Region from 2014 to 2018 and to derive information that will provide a basis for improving the drinking water quality in the region. Monitoring data for drinking water from the Inner Mongolia Autonomous Region for 2014 to 2018 were analyzed and the results were compared with GB 5749-2006, the Standard Test Method for Drinking Water, and GB 5749-2006, the Drinking Water Quality Standards. Data for a total of 30,613 water samples were assessed. Of the data for the microbiological index, sensory trait and general chemical index, and toxicological index, 89, 80, and 69% were qualified, respectively. For the toxicological index, the fluoride and nitrate nitrogen data were the least compliant. The water quality in all the cities was generally very suitable for drinking. However, there were marked differences in the qualified rates of drinking water in different areas and the qualified rates of the data for the three indexes were lower in rural areas than in urban areas. Given the varied issues with the drinking water quality, the relevant departments of League cities should implement appropriate and effective treatment measures to improve the drinking water quality and ensure it is safe for residents.

Arsenic (As) contamination in groundwater presents a major health and environmental concern. As is found in two oxidation states and most chemical tests for inorganic arsenic are focused on As(III), and few have been developed for As(V). We developed the simple analytical method for determining As(V) concentrations in groundwater using CeO2NPs and fluorescein (FAM)-labeled DNA. Prior to sample measurements, we investigated the key operational parameters that affect the sensing performance. The optimal CeO2NPs final concentration, FAM-labeled DNA final concentration, the sequence and length of FAM-labeled DNA, and incubation time were 15 μg/mL, 400 nM, 6-mer poly-cytosine sequence, and 6 min, respectively. After optimizing the parameters, the total analysis time was about 20 min and the limit of detection was 0.61 μM. This method has a high selectivity against the same concentrations of Cu(II), Cd(II), Hg(II) and Pb(II). Pretreatment by cation extraction to remove interfering ions was beneficial for determination of As(V) concentrations in groundwater containing a variety of metal cations at high concentration. We could determine As(V) concentration in groundwater. Modification of the reactions of the method is necessary. This study provides the first step in the development of a simple method for on-site As(V) analysis.

Durante as operações de usinagem, o atrito entre a ferramenta e a peça gera calor, levando ao desgaste ou perda de propriedades da ferramenta de corte, além de distorções na peça usinada. Para resfriar e lubrificar as operações de usinagem, são aplicados fluidos de corte, os quais, quando descartados de maneira inadequada, podem gerar danos ao meio ambiente. Esta pesquisa tem como objetivo estudar a possibilidade de reciclagem, por filtração a partir de aparato simples, de dois tipos de fluidos de corte aplicados em processos de torneamento. Além disso, avaliar se estes fluidos filtrados mantém suas propriedades de maneira a permanecerem aptos a serem novamente aplicados, minimizando a necessidade de descarte dos mesmos. Para tanto, os fluidos de corte utilizados foram coletados por um recipiente acoplado ao torno, filtrados por um aparelho confeccionado com materiais de fácil acesso e submetidos a análises físico-químicas. Análises da rugosidade das peças usinadas com fluidos de corte novos e reciclados também foram realizadas. Os resultados relativos aos fluidos novo e utilizados, após a filtração, foram comparados. Verificou-se que os fluidos reciclados tiveram um bom desempenho, podendo ser reciclados sem gerar perdas ao processo, mas levando em consideração algumas condições, como o tempo de reaproveitamento.
