Conspiracy trend in everyday practices of social reflection. Theoretical generalisations
Authors: Sergeev Vsevolod
Published: June 2022

The article provides a generalized description of such a specific form of social cognition as conspiracy theory. It is emphasised that in the current context, conspiracy thinking can no longer be interpreted as marginal, since it is widely spread as one of the available ways for individuals and groups to reflect on the ambiguous phenomena of social life, primarily related to security threats. Regardless of what final product is produced by the conspiracy theorist – mundane explanations, exotic social, (pseudo)religious concepts, political and geopolitical doctrines, etc. – they are all united by a single conceptual structure (denoted in the work as the “ontological minimum”) and are the result of certain psychological mechanisms. Some similarity of conspiracy theories with the critical direction of philosophical and, more broadly, intellectual thought (in terms of identifying practices of coercion and combating them) is emphasised, with an important caveat about their significant differences (as a rule, an incomparable conceptual level, "excessive", "unsaturated" skepticism etc.).

When characterizing conspiracy theories, the position of research particularism seems quite justified - the avoidance of a generalized assessment of all ideas with signs of a conspiracy theory, since there is no single rigid criterion. Approaches based on the application of a single criterion to conspiracy theories (conspiracy as a “bad science”, psychopathological discourse, etc.) have limited potential and, if applied systematically, can be criticised for unfounded generalisations (in fact, for the same things that conspiracy theories are criticized for).

On a continuum of variables relevant to understanding conspiracy theories (psychological, social, etc.), most proven connections are not of a hard causal nature. Understanding specific constructions involves identifying exactly how such variables are combined in a particular theory. The above generalised characteristics can become a theoretical basis for empirical studies of the conspiracy trend in the practice of everyday reflection on social problems, primarily existential threats.

Authors:   Korean Comparative Education Society, Yang Ludan , Hong Hoo Jo
Published: June 2022

The purpose of this study was to find out the characteristics that appear based on the teachers' actual experience in implementing the IB DP curriculum in a situation where the number of schools introducing the IB DP in China is rapidly increasing. By examining the difficulties they are experiencing, intending to explore the direction of activation for effective implementation. In order to achieve the purpose of the study, 5 Chinese teachers with more than 3 years of experience in IB DP subjects were interviewed. The main research results are as follows. Teachers highly evaluated the comprehensive and balanced course composition and rational evaluation structure. But they complained about the difficulties of increased workload and complicated classroom situations in the class.
And teachers pointed out the ambiguity of the IBO evaluation criteria and the inconsistency of the evaluation methods of each school. Through the results of the study, it was confirmed that the teachers were actively participating in the active growth and promotion of IB DP education in China, and it was found that teachers were experiencing difficulties in the process of implementing IB DP in the class. Based on this, it emphasized the need for long-term cooperation between educational administrative agencies related to international education in China, schools operating IB DP, and teachers who implement IB DP for effective implementation of the IB DP curriculum.

CALCULATIONS OF DATUM STATICS IN REFLECTION METHOD WITH CONSIDERATION TO THE POSITION OF THE CHARGE RELATIVE TO THE BASE OF LOWVELOCITY LAYER
Authors:   Saint Petersburg Mining University, Saint Petersburg, Russia, Sysoev A. P. , Shamordin A. A. ,   Saint Petersburg Mining University, Saint Petersburg, Russia
Published: June 2022

While processing ground-based seismic operations by the reflection method using an explosive excitation source, the standard method of compensation technique for the inhomogeneity of the low velocity layer (LVL) is based on the use of blastholes parameters: shot depth, TSP and velocity of underlying stratum, determined by the apparent velocity of refracted wave. The necessary condition for the applicability of this method is the arrangement of the charge below the base of the LVL. Therefore, to substatiate this method, it is necessary to evaluate the position of the charge relative to the roof of the LWL for each source. If the necessary condition for calculating statics computations is not met, it is necessary to solve the problem of estimating the LVL’s thickness and velocity. The presented work contains the problem of analyzing the position of the charge relative to the LVL’s position and estimating the layer parameters which is solving on the basis of joint analysis of the parameters of wells and wave refracted on the LVL base. The solution of the problem is illustrated by the example of real data processing.

Authors: Al-Ashwal A. Y. , Al-Mawgani A. H. M. , Al-Arashi Waled Hussein
Published: June 2022

Image steganography is the art of information hiding, which embeds a secret data into a cover image. However, high capacity of secret data and high quality of stego image are key issues in image steganography. In this paper, an image steganography technique based on Haar Discrete Wavelet Transform (HDWT), Lempel Ziv Welch (LZW) algorithm and Optimal Pixel Adjustment Process (OPAP) is proposed. The HDWT is used to increase the robustness of stego image against attacks. To increase the hidden capacity, LZW algorithm is performed on the secret message. The OPAP is then applied to reduce the embedding error between the cover image and stego image. The experimental results are evaluated by four standard images as covers, and with two types of secret messages. The results demonstrate high visual quality of stego image with large Hidden Capacity (HC) of secret data compared with recent techniques

Published: June 2022

This study aims to investigate a way to reduce transmitted x-ray through cement shielding. A cement shielding which painted by Barium Sulfate capable of absorbing a significant portion of X-ray was used with different thickness and composition. The measurements were recorded at various applied voltages (50 kVp to 120 kVp), and the transmitted and backscattered x-ray was measured using ion chamber. The results showed that the cement shielding painted by Barium Sulfate was very effective in the absorption of incident x-ray up to about 95%, and has the ability to reduce backscattered x-ray radiation up to about 75 % by using fabricated iron steel grid based on a plate composed from cement shielding painted by Barium Sulfate.

Authors: Alhammadi Asem , Zain Adnan A.
Published: June 2022

Long Term Evolution-Advanced (LTE-A) is a Fourth Generation (4G) standard of wireless communications that introduces high data rate, high performance, and low delay. These features of LTE-A resulted from the new techniques developed for wireless communications such as Multiple-Input Multiple-Output (MIMO) technique. At the heart of this technique is the Space Time Codes, which were developed by the researchers in recent decades to achieve the mentioned features. The designs of OSTBC codes for MIMO systems having any number of transmit antennas and any number of receive antennas have attracted the attention of many researchers. Based on the theory of real and complex orthogonal designs, this paper deals with the design of real and complex OSTBC codes to be used with real signal set constellation such PAM and complex signal constellation such as PSK and QAM. Real and complex OSTBC codes for MIMO systems with two, three, four, five, six, seven and eight transmit antennas and any number of receive antennas, are presented. Simple linear processing ML decoders are derived and presented. The used channel is Rayleigh fading channel MIMO and assumed to behave in a “quasi-static” fashion. Finally, the performances of OSTBC schemes were evaluated and compared in terms of the Bit Error Rate (BER) and Signal to Noise Ratio (SNR). The environment of simulation is MATLAB which is a powerful tool for mathematical calculation and system simulation. The methods of modulations chosen are QPSK, 16QAM, 64QAM, and 128QAM with gray scale mapping.

Modeling Water Supply and Demand for Effective Water Management in the Sana’a Basin in Yemen
Authors: Zamzam Mubarak  , Wail Alderwish
Published: June 2022

Modelling system is the core for the evaluation of water related sectors in the Sana’a Basin. The numerical modelling (MODFLOW) has emerged as an effective tool for managing groundwater resources and predicting future responses, especially when dealing with complex aquifers systems and heterogeneous formations. MODFLOW model has been used herein as a management tool for the targeted sub- basins in Sana’a Basin such (Wadi Bani Hawat, Wadi Dhahr & Al-Ghayl, Wadi Hamdan & As Sabrahand Wadi Ghayman); the most important groundwater resources for domestic and agricultural sectors in Sana’a basin. A conceptual model was designed according to the actual groundwater dynamic flow system in the 2010 Hydrosult Sana’a Basin Model. Also, the governing partial parabolic differential equation was defined, including the vertical conductivity flow between the aquifers. Total groundwater abstraction values from previous studies were compiled, including the 2015 well inventory data of National Water Resources Authority –Sana’a Basin.In this study, three simulations of groundwater development scenarios were distinguished. The first scenario is applied for evaluation of the present status and till 2025. The second and thethird scenarios are focused on the effect of water augmentation i.e. decrease the present rate of groundwater abstraction to 30% and 50% respectively, with considering the highly intervention of IWRM structure of Sana’a basin on the on-going activities related to change land use, change crop pattern, value chain, marketing, modern irrigation techniques, water harvesting techniques, treated waste reuse etc…. Also other Modules were used in calculating the groundwater demand, deficit and unemployment in agricultural sector inSana’a Basin. Scenario 3 gives a remarkable improvement of the water resources system in the four sub-basins within a reasonable period (in the year 2025), thus, it will keep the water resources sustainability; but the unemployment in agricultural sector in Sana’a Basin in scenario 3 will be is the highest value if comparing with the other two scenarios. It will reachin 2025 under scenario 2 and scenario 3 to 10432 and 14762 respectively while in scenario 1 the unemployment will disappeared in 2025. This study is recommended that irrigation systems should be improved, usage of harvesting water methods and treated waste water reuse for agriculture to avoid the depletion of Sana’ Basin aquifer and to reduce unemployment in agricultural sector in Sana’a Basin.

MonkeyPox2022Tweets: The First Public Twitter Dataset on the 2022 MonkeyPox Outbreak
Authors: Thakur Nirmalya
Published: June 2022

The world is currently facing an outbreak of the monkeypox virus, and confirmed cases have been reported from 28 countries. Following a recent “emergency meeting”, the World Health Organization is considering whether the outbreak should be assessed as a “potential public health emergency of international concern” or PHEIC, as was done for the COVID-19 and Ebola outbreaks in the past. During this time, people from all over the world are using social media platforms, such as Twitter, for information seeking and sharing related to the outbreak, as well as for familiarizing themselves with the guidelines and protocols that are being recommended by various policy-making bodies to reduce the spread of the virus. This is resulting in the generation of tremendous amounts of Big Data related to such paradigms of social media behavior. Mining this Big Data and compiling it in the form of a dataset can serve as a data resource for a wide range of use-cases and applications such as analysis of public opinions, interests, views, perspectives, attitudes, and sentiment towards this outbreak. Therefore, this work presents MonkeyPox2022Tweets, an open-access dataset of Tweets related to the 2022 monkeypox outbreak that were posted on Twitter since the first detected case of this outbreak on May 7, 2022. The dataset is compliant with the privacy policy, developer agreement, and guidelines for content redistribution of Twitter, as well as with the FAIR principles (Findability, Accessibility, Interoperability, and Reusability) principles for scientific data management.
A Short Study on Minima Distribution
Authors: Nguyen Loc
Published: June 2022

Global optimization is an imperative development of local optimization because there are many problems in artificial intelligence and machine learning requires highly acute solutions over entire domain. There are many methods to resolve the global optimization, which can be classified into three groups such as analytic methods (purely mathematical methods), probabilistic methods, and heuristic methods. Especially, heuristic methods like particle swarm optimization and ant bee colony attract researchers because their effective and practical techniques which are easy to be implemented by computer programming languages. However, these heuristic methods are lacking in theoretical mathematical fundamental. Fortunately, minima distribution establishes a strict mathematical relationship between optimized target function and its global minima. In this research, I try to study minima distribution and apply it into explaining convergence and convergence speed of optimization algorithms. Especially, weak conditions of convergence and monotonicity within minima distribution are drawn so as to be appropriate to practical optimization methods.
TitleClimate Change will Weaken the Ability of Natural Enemies to Control the Asian Longhorned Beetle, Anoplophora glabripennis (Coleoptera: Cerambycidae)
Authors: Zhang Quancheng , Wang Jungang , Lei Yonghui
Published: June 2022

The Asian longhorned beetle (ALB), Anoplophora glabripennis is a forestry pest found worldwide. ALB causes serious harm because of the lack of natural enemies in the invaded areas. Dastarcus helophoroides and Dendrocopos major are important natural enemies of ALB. MaxEnt was used to simulate the distribution of D. helophoroides and D. major in China and Xinjiang, and their suitable areas were superimposed to evaluate the pest control ability of D. helophoroides and D. major. The results showed that, with climate change, the suitable areas of D. helophoroides and D. major migrated northward; the centroid shift of ALB was greater than that of D. helophoroides and D. major, which would lead to fewer natural enemies encountered by ALB during migration, reduce the control ability of natural enemies, and increase the risk of disastrous outbreaks in the invaded areas. We found that the damage caused by ALB was not serious in the areas with natural enemies and very serious in the areas without natural enemies. We suggest that natural enemies should be included in the model used for predicting suitable areas for invasive pests, as this is more conducive to assessing the risks of invasive organisms to the local ecological environment.

Published: June 2022

We studied surface enhanced Raman spectra of amino acids D-alanine and DL-serine and their mixture on silver nanoisland films (SNF), immersed in phosphate buffer saline solution at millimolar amino acid concentrations. It is shown that the spectra from the amino acid solutions differ from the reference spectra for microcrystallites due to electrostatic orientation of amino acid zwitterions by the metal nanoisland film. Moreover, non-additive peaks are observed in the spectrum of the mixture of amino acids adsorbed on SNF, which means that intermolecular interactions between adsorbed amino acids are very significant. The results indicate the need for a thorough analysis of the Raman spectra from amino acid solutions in the presence of a nanostructured metal surface, and may also be of interest for studying molecular properties and intermolecular interactions.
Unveiling the Core Effector Proteins of Oil Palm Pathogen Ganoderma boninense via Pan-secretome Analysis

Published: June 2022

Ganoderma boninense is the major causal agent for the basal stem rot (BSR) disease in oil palm, causing the progressive rot of the basal part of the stem. Despite its prominence, key pathogenicity determinants for the aggressive nature of hemibiotrophic infection remain unknown. In this study, genome sequencing and annotation of G. boninense T10 were carried out using the Illumina sequencing platform and comparative genome analysis was performed with previously reported G. boninense strains (NJ3 and G3). The pan-secretome of G. boninense was constructed and comprised of 937 core orthogroups, 243 accessory orthogroups, and 84 strain-specific orthogroups. A set of core candidate effector proteins (CEPs) were found to be enriched with catalytic protein classified as the carbohydrate-active enzymes, hydrolases as well as non-catalytic proteins. Differential expression analysis revealed an upregulation of CEP genes which was linked to the suppression of PTI signaling cascade while the downregulation of CEP genes was linked to the inhibition of PTI by preventing host defense elicitation. Genome architecture analysis revealed the one-speed architecture of the G. boninense genome and the lack of preferential association of CEP genes to the transposable elements. The findings obtained from this study would aid in the characterization of pathogenicity determinants and molecular biomarkers of BSR disease.

Skin image analysis using artificial intelligence (AI) has recently attracted significant research interest, particularly for analyzing skin images captured by mobile devices. Acne is one of the most common skin conditions with profound effects in severe cases. In this study, we developed an AI system called AcneDet for automatic acne object detection and acne severity grading using facial images captured by smartphones. AcneDet includes two models for conducting two tasks: (1) a Faster R-CNN-based deep learning model for the detection of acne lesion objects of four types including blackheads/whiteheads, papules/pustules, nodules/cysts, and acne scars; and (2) a LightGBM machine learning model for grading acne severity using the Investigator’s Global Assessment (IGA) scale. The output of the Faster R-CNN model, i.e., the counts of each acne type, were used as input for the LightGBM model for acne severity grading. A dataset consisting of 1,572 labeled facial images captured by both iOS and Android smartphones was used for training. The results show that the Faster R-CNN model achieves a mAP of 0.54 for acne object detection. The mean accuracy of acne severity grading by the LightGBM model is 0.85. With this study, we hope to contribute to the development of artificial intelligent systems that are able to help acne patients understand more about their conditions and support doctors in acne diagnosis.

Published: June 2022

Objectives. To investigate resilience strategies used by Black gay, bisexual, and other men who have sex with men (MSM) to navigate racism and heterosexism.

Methods. In 2019, we conducted in-depth interviews with 46 Black MSM in Milwaukee, Wisconsin, and Cleveland, Ohio. Thematic analysis, informed by intersectionality, was used to identify intersectional resilience within the context of participants’ lives.

Results. Our analyses revealed ways in which Black MSM respond to stigma and oppression. We identified the following themes that capture these experiences: pride in intersectional identities, perseverance, community advocacy, and social support. Our analyses reveal how men draw on these assets and resources to positively adapt despite experiences of racism and heterosexism.

Conclusions. Intersectional resilience can support Black MSM in navigating racism and heterosexism. However, public health interventions at the institutional and system levels are needed to directly target the root causes of oppression and support resources that facilitate intersectional resilience.

Researchers are increasingly recognizing the importance of studying and addressing intersectional stigma within the field of HIV. Yet, researchers have, arguably, struggled to operationalize intersectional stigma.

To ensure that future research and methodological innovation is guided by frameworks from which this area of inquiry has arisen, we propose a series of core elements for future HIV-related intersectional stigma research. These core elements include multidimensional, multilevel, multidirectional, and action-oriented methods that sharpen focus on, and aim to transform, interlocking and reinforcing systems of oppression. We further identify opportunities for advancing HIV-related intersectional stigma research, including reducing barriers to and strengthening investments in resources, building capacity to engage in research and implementation of interventions, and creating meaningful pathways for HIV-related intersectional stigma research to produce structural change.

Ultimately, the expected payoff for incorporating these core elements is a body of HIV-related intersectional stigma research that is both better aligned with the transformative potential of intersectionality and better positioned to achieve the goals of Ending the HIV Epidemic in the United States and globally.

Performance Evaluation of High-Strength Polyethyleneimine Gels and Syneresis Mechanism under High-Temperature and High-Salinity Conditions
Authors: Guo Hongbin , Ge Jijiang , Zhao Sai , Xu Ya , Zhou Daiyu , Tao Zhengwu
Published: June 2022

A high-strength gel was prepared by crosslinking a high-concentration but low molecular weight polyacrylamide-tert-butyl acrylate (PAtBA) copolymer with polyethyleneimine (PEI), and the various factors affecting the gelling were systematically evaluated. The results showed that, besides the concentration of polymer and crosslinker, the molecular weight of PEI, pH value and salinity of gelant, and temperature all affected the gelation time, gel strength, and stability. High-strength PAtBA-PEI gels could be stable for more than 240 days in synthetic brine with salinity less than 43 530 mg/L at a temperature not higher than 130°C. However, when the temperature is higher than 150°C, the gel would be broken within 60 days. When the salinity in the synthetic brine was too high, the gel also exhibited syneresis at 110°C within 15 days. X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared spectroscopy (FTIR) analysis showed that the syneresis of PAtBA-PEI gel under high-salinity conditions was caused by the reaction of carboxylate group generated by the hydrolysis of the amide group with divalent cations. In addition, Cryo-scanning electron microscope (Cryo-SEM) analysis showed that high-strength PAtBA-PEI gels had high crosslinking density and poor deformation ability. Nevertheless, the results of rheological tests and flooding experiments showed that the low deformation ability of the gel did not affect the sealing ability of the gel, and the high storage modulus and yield stress of the gel enabled it to exhibit high breakthrough pressure and residual resistance factor in the core. The results of this study are instructive for the field application of PEI gels.

Background
Impacts of nationally directed malaria control interventions hinge on understanding malaria transmission and prevention at the community level. The decision to seek care or health seeking behaviors provide valuable insight on knowledge of malaria, access to care, and efficacy of malaria case management. Thus far, few studies have focused on central Mozambique. Our aim was to describe community level P. falciparum prevalence and health seeking behaviors among residents of Sussundenga, Mozambique, a rural village in Manica Province with high malaria incidence reported at the Sussundenga-Sede health center (RHC).

We conducted a cross-sectional community-based survey from December 2019 – February 2020. We used a random household sampling method, based on enumerated households from satellite imagery. All consenting participants completed a survey about malaria risk, prevention, and health seeking-behaviors, and received a P. falciparum malaria rapid diagnostic test (RDT).
Results
We enrolled 358 individuals from 96 households. The P. falciparum prevalence was 31.6% (95% CI [26.6%-36.5%]). Ninety-three percent of participants reported using the Sussundenga-Sede RHC for healthcare. Sixty-six percent of participants (N = 233) experienced at least one malaria symptom in the past month, with self-reported fever most frequently reported (19.3%). Of these, 176 (76.5%) sought care in a health facility and 174 (79%) received an RDT with 130 (63%) having a positive test. Of those with a positive RDT, 127 (97%) received Coartem®. Following treatment, 123 (97%) participants' symptoms resolved within a median of 3 days (IQR: 3–5) ranging from 2–14 days. In this high transmission setting, a high proportion of participants recognized malaria related symptoms then received a proper diagnostic test and treatment in a health facility.
Conclusions
Future interventions that leverage this health seeking behavior and strengthen health systems for community interventions will improve malaria control and inform the efficacy of potential interventions at this particular international border.

Multi-MeV high-purity proton acceleration by using a hydrogen cluster target irradiated with repetitive, relativistic intensity laser pulses has been demonstrated. Statistical analysis of hundreds of data sets highlights the existence of markedly high energy protons produced from the laser-irradiated clusters with micron-scale diameters. The spatial distribution of the accelerated protons is found to be anisotropic, where the higher energy protons are preferentially accelerated along the laser propagation direction due to the relativistic effect. These features are supported by three-dimensional (3D) particle-in-cell (PIC) simulations, which show that directional, higher energy protons are generated via the anisotropic ambipolar expansion of the micron-scale clusters. The number of protons accelerating along the laser propagation direction is found to be as high as 1.6±0.3 × 109 /MeV/sr/shot with an energy of 2.8±1.9 MeV, indicating that laser-driven proton acceleration using the micron-scale hydrogen clusters is promising as a compact, repetitive, multi-MeV high-purity proton source for various applications.

Background
The purpose of this study was to introduce the arthroscopic internal drainage with anterior-anteromedial approach for the treatment of popliteal cysts in children. To compare its clinical efficacy with open surgery.
Methods
This was a retrospective case-control study of 102 patients diagnosed with popliteal cysts from January 2018 to February 2020 who received surgery. The study included 27 cases with minimally invasive group (MI group) and 75 cases with open surgery group (OS group). The MI group included 21 males and 6 females, age 6.71 ± 2.16 years who received arthroscopic internal drainage of the cysts to adequately widen the valve opening between the cyst and the articular cavity, excised the fibrous diaphragm without complete excision of the cyst wall. The OS group included 57 males and 18 females, age 6.21 ± 1.67 years who received open excision. The clinical parameters regarding the preoperative characteristics and surgical results were compared. Ultrasound or MRI was used to identify the recurrence of the popliteal cysts. Rauschning-Lindgren grade was recorded to evaluate the clinical outcome.
Results
All patients were followed up for at least 24 months. There were no significant differences between the two groups in age, gender, left and right sides, disease time, cyst size, length of hospitalization, preoperative Rauschning-Lindgren grade (p > 0.05). At the last follow-up, the preoperative and postoperative Rauschning-Lindgren grade was improved in both groups. Compared with the OS group, operation time was significantly shortened in the MI group (28.89 ± 4.51 min vs 52.96 ± 29.72 min, p < 0.05). The MI group was superior to the OS group in terms of blood loss and plaster fixation, with statistical significance (p < 0.05). There was obvious difference in recurrence rate between the two groups (0% vs 17.33%, p = 0.018). No postoperative complications occurred during the follow-up period.
Conclusions
Compared with open excision, the treatment of popliteal cyst in children by arthroscopic internal drainage to expand the articular cavity and eliminate the “one-way valve” mechanism between the cyst and the articular cavity exhibits better clinical outcomes and significantly reduces the recurrence rate, which is worthy of further clinical promotion.

In this work, a novel Z-scheme heterojunction of ZIF67/WO3 nanocomposite is successfully prepared via immobilizing WO3 on the MOFs ZIF67 and confirmed by measuring XRD, FT-IR, XPS, SEM, TEM, and EDS. UV-vis and Mott-Schottky measurements. The photocatalytic activity of the as-prepared ZIF67/WO3 is evaluated by degrading methylene blue (MB) solution under simulated visible light irradiation. Obviously, the optimal ZIF67/WO3-0.3 (designated as 0.3 g addition of WO3) delivers significant photocatalytic degradation exceeding 90% toward MB within 120 min, which is about 3.0 and 4.2 times higher than those of pure ZIF67 (30.0%) and WO3 (21.2%), respectively. The effects of pH, initial concentration of MB, and WO3 dosage in ZIF67/WO3 on the photocatalytic elimination efficiency for MB degradation are also evaluated. Reactive species scavenging experiments indicated that the holes (h+) and hydroxyl radical (·OH) are mainly responsible for MB degradation. Moreover, the probable reaction mechanism is elucidated by detecting the intermediates by performing LC-MS measurements. The excellent photocatalytic performance of the ZIF67/WO3 is predominantly determined by the structural properties of the composite and the Z-scheme charge transfer pathway, which promote the efficient separation of photogenerated carriers and facilitate the transfer of photogenerated electrons to active sites. Therefore, it is a promising strategy by immobilizing the WO3 on MOFs for constructing Z-scheme heterojunction to degrade the refractory organic dyes.

Laryngeal squamous cell carcinoma (LSCC) is one of the most common head and neck cancers. Rho-associated kinase1 (ROCK1) is believed to promote progression of most cancers, however, its role in LSCC is still unknown. Here, ROCK1 is highly expressed in LSCC tissues, and high ROCK1 expression correlates with advanced stage and poor survival prognosis for LSCC patients. Decreasing ROCK1 expression inhibits the proliferation, migration and invasion. Conversely, increasing ROCK1 expression has the opposite experimental results. FAK signalling pathway plays an essential role in promoting LSCC progression. Inhibiting FAK activity with TAE226 observably impairs the tumor-promoting effects. In conclusion, ROCK1 promotes LSCC tumorigenesis and progression via the FAK pathway, targeting ROCK1 molecule may provide a potential treatment strategy for LSCC.

In this work a bi-parametric, highly selective, electrical calcium detecting platform is fabricated. The fabricated detector consists of porous silicon substrate which is surface functionalized by calmodulin. The use of porous silicon provides many fold increment in surface area, facilitating effective absorption, whereas, calmodulin functionalization upon the porous surface provides excellent calcium attachment sites. The electrical parameters of this detecting platform are then tested with calcium and several other ionic solutions, at concentration relevant physiologically. The fabricated detector showed tremendous selectivity towards calcium ion. Even in mixture ionic solution the detector exhibited its high discrimination towards calcium ion. Thus the fabricated detecting platform can work as an effective calcium detector. Its bi-parametric approach provides enhanced calcium detection efficiency. Hence the detector imparts a highly selective, robust, label free and cost-effective alternative for calcium detectors, effective even in biologically relevant concentrations. Later a comparative study is performed between the optical and electrical response of the detector platform to provide a better understanding of the consistency of the detector developed that in future will facilitate multi-parametric approach to enhance the response, selectivity and thus the efficiency of the detector platform developed in this work.
