Received Jul 23, 2021 Revised Dec 22, 2021 Accepted Jan 3, 2022 Human activity recognition, in computer vision research, is the area of growing interest as it has plethora of real-world applications. Inferring actions from one or more persons captured through a live video has its immense utility in the contemporary era. Same time, protecting privacy of humans is to be given paramount importance. Many researchers contributed towards this end leading to privacy preserving action recognition systems. However, having an optimized model that can withstand any adversary models that strives to disclose privacy information. To address this problem, we proposed an algorithm known optimized prediction algorithm for privacy preserving activity recognition (OPA-PPAR) based on deep neural networks. It anonymizes video content to have adaptive privacy model that defeats attacks from adversaries. The privacy model enhances the privacy of humans while permitting highly accurate approach towards action recognition. The algorithm is implemented to realize privacy preserving human activity recognition framework (PPHARF). The visual recognition of human actions is made using an underlying adversarial learning process where the anonymization is optimized to have an adaptive privacy model. A dataset named human metabolome database (HMDB51) is used for empirical study. Our experiments with using Python data science platform reveal that the OPA-PPAR outperforms existing methods.
Structural and Optical Properties of CdSe/CdTe Core-Shell Quantum Dots

A simple hydrothermal method is developed for the synthesis of high-quality type II core-shell CdSe/CdTe quantum dots (QDs). The XRD results reveal the formation of mixed phases of CdSe and CdTe with a grain size of 12.6nm. SEM morphology con ﬁ rms the uniformly distributed nanoscale CdSe/CdTe with no agglomeration. EDX con ﬁ rms the elemental presence of Cd, Se, and Te in the compound. TEM results suggest that the size of spherical CdSe/CdTe core-shell QDs is in the range of 8 ~ 10 nm. Signi ﬁ cant results of the SAED pattern con ﬁ rm the core and shell components as CdSe and CdTe, respectively. The correlation between the synthesis procedures and the corresponding structures of the core-shell CdSe/CdTe QDs is discussed. The demonstrated monodispersed lattice structure of core-shell CdSe/CdTe QDs has excellent PL emission properties at λ emi ~ 585nm which is suitable for photovoltaic applications. The UV-Vis absorption bands at 455nm and 560 nm con ﬁ rm exciton emission due to the type II matrix of CdSe/CdTe QDs.
HAEMATOPOETIC EFFECT OF ETHYL ACETATE FRACTION OF HONEYCOMB IN RATS

Ethyl acetate fraction (Ec4) of honeycomb was evaluated for acute toxicity and haematopoietic effects in rats using standard methods. Oral LD50 of fraction Ec4 was 5000 mg/kgbw. Oral administration of Ec4 (25 mg/kgbw, 50 mg/kgbw and 100 mg/kgbw) for 28days did not cause any variation in neutophils, lymphocytes, monocytes, WBC, RBC PCV, MCHC, MCV and platelet counts of rats. Fraction Ec4 at 100mg/kgbw evoked an insignificant (P>0.05) increase in the levels of basophil and significant (P<0.05) decrease in eosinophil counts in treated rats compared with the control. The results of this study revealed the potentials of honeycomb in stabilizing the immune system. Therefore, the fraction could be standardized and developed into affordable and acceptable phytomedicine for various ailments. But caution should be exercised on chronic exposure since it is capable of causing allergy in rats.

Endothelial Nitric Oxide Synthase (eNOS) as a Therapeutic Target in Type 2 Diabetes Mellitus and Its Vascular Complications: A Narrative Review

Diabetes mellitus type 2 (T2DM) has been a global health problem. Current studies have shown that the increased mortality and morbidity in T2DM are related to vascular complications. The vascular complications were caused by increased reactive oxygen species (ROS) associated with chronic hyperglycemia and insulin resistance. The increase of ROS in T2DM was influenced by the p38 MAPK pathway which is directly related to the modulation of nitric oxide (NO) produced by endothelial nitric oxide synthase (eNOS) of endothelium cells. The decrease of NO by eNOS also has a connection with an event known as eNOS uncoupling. The decrease of eNOS plays a role in the pathogenesis of T2DM and its vascular complications such as increased inflammatory pro-cytokine, activation of NADPH pathway, increased of AGEs, VCAM-1, ICAM-1, and also the activation of protein kinase c and Rho-kinase pathway. Some interventions indirectly or directly have modulated NO relayed to its work targets such as oral antidiabetic drugs (metformin, sulfonylurea, and acarbose) or some polyphenol compounds such as emodin, α-Lipoic acid, curcumin, and olive oil. Modulation of NO in these interventions can be strong evidence that NO can be a target for further therapy in the management of T2DM and its complications. Keywords: eNOS, vascular complication, Type 2 Diabetes mellitus.
Simulation and Experiment of Molded Underfill Voids

The molded underfill (MUF) has become one of the trends in the IC packaging industry due to its simplification of assembly process steps and the saving of the cost. However, for the fine pitch flip chip bumping array, the void generation is one serious issue causing the short of the electrical connections and the cracking of the bumps. In this paper, the main focus is to predict the void generation and to compare with the experimental data. The early stage FEM numerical simulation not only can predict the risk of voids but also provide the best economic approach without the need to spend trial and error budget. A multiple segments substrate strip, with totally 64 packages populated on it, is used in the experiment. The manufacturing process parameters are programmed and recorded for comparison. The filling, packing, and curing of molding compound are carefully chosen in order to compare their effects. After the assembly process, each package is scanned with C-SAM inspection to check if the voids appear. For FEM numerical simulation, only one segment of the substrate strip, with totally 16 packages, is modeled to save computational resources and time. However, all the bumps, on each of the package, are modeled in order to check how the flow field is affected by the packages. In conclusion, we have obtained good match of experimental vs. simulation data. The prediction of voiding location is very close to each other.
14-bit 20 μW column-level two-step ADC for 640 × 512 IRFPA

A column-level two-step analogue-to-digital converter (ADC) structure for infrared focal-plane array (IRFPA) is proposed. The first step adopts a 16-column-shared 6-bit flash ADC to accomplish the coarse conversion of 16 columns one by one. Owing to the staggered code and correction, a dynamic comparator is adopted in the flash ADC and the power dissipation of a flash ADC averaged to one column in period is only 0.386 μW. The second step is SAR conversion of which the cycle time is prolonged. The input voltage variation of the comparator in the charge redistribution structure is decreased to tens of millivolts; so a 1.8 V power supply is adequate in spite of 5 V V FS. The power dissipation of this comparator is reduced to 5.966 μW. Also, the lower clock frequency of the SAR logic reduces the dynamic power. A 14-bit two-step ADC is designed in 0.18 μm process and the equivalent power dissipation of the proposed ADC structure for one column is <20 μW.
26 Years of Strategic Technology Partnering: Trends, Patterns and Future Prospects in Research Through Frequency Analysis

Many firms are increasingly cooperating in their technological undertakings. They engage in strategic technology partnerships (STP) for technological, commercial, industrial, and financial reasons. STP is deemed imperative for easing the access to strands of technologies that are unknown to a company. This frequency analysis on STP bases on systematic literature review (SLR) approach and provides a thorough review of 57 articles published in highly-ranked peer-reviewed journals, spanning a 26-year period from 1988 to the beginning of 2014. Research on STP is somewhat fragmented which renders some of the research studies irreconcilable and impedes a greater understanding and consistency of the discipline. There is still a growing body of literature on the subject matter from various disciplinary perspectives adopting different theoretical and methodological lenses at diverse levels of analysis. In the present paper, we analyse among other things the various methodological, research and theoretical issues underpinning STP and propose a research agenda. Hence, we contribute to the existing body of knowledge the STP literature that currently exists by offering a state-of-the-art overview of the current research and elaborating on promising areas for further investigation.
MOOCs and personalized massification

One area that will be able to strengthen and expand the tutorials possibilities in a near future is a field of artificial intelligence which has experienced significant developments in recent years; this field is called recommender systems and nowadays you can find important experiences in which, regardless of the number of students, learning processes are served and supported. This article reflects on the potential of artificial intelligence and its role in the development of MOOCs.
Nonlinear Response and Stability Analysis of Vessel Rolling Motion in Random Waves Using Stochastic Dynamical Systems

Nonlinear Response and Stability Analysis of Vessel Rolling Motion in Random Waves Using Stochastic Dynamical Systems. (August 2012) Zhiyong Su, B.S.; M.S., Shanghai Jiao Tong University Chair of Advisory Committee: Dr. Jeffrey M. Falzarano Response and stability of vessel rolling motion with strongly nonlinear softening stiffness will be studied in this dissertation using the methods of stochastic dynamical systems. As one of the most classic stability failure modes of vessel dynamics, large amplitude rolling motion in random beam waves has been studied in the past decades by many different research groups. Due to the strongly nonlinear softening stiffness and the stochastic excitation, there is still no general approach to predict the large amplitude rolling response and capsizing phenomena. We studied the rolling problem respectively using the shaping filter technique, stochastic averaging of the energy envelope and the stochastic Melnikov function. The shaping filter technique introduces some additional Gaussian filter variables to transform Gaussian white noise to colored noise in order to satisfy the Markov properties. In addition, we developed an automatic cumulant neglect tool to predict the response of the high dimensional dynamical system with higher order neglect. However, if the system has any jump phenomena, the cumulant neglect method may fail to predict the true response. The stochastic averaging of the energy envelope
Performance Evaluation of Cyclic Stability and Capacitance of Manganese Oxide Modified Graphene Oxide Nanocomposite for Potential Supercapacitor Applications

Supercapacitors are a revolutionary type of energy storage device. They must be able to charge and discharge quickly while maintaining a high energy density. A storage material’s cyclic stability is a desirable feature. The type of electrode materials employed for the specific study design affects supercapacitor performance. Manganese dioxide has long been regarded as one of the best and most abundant materials in nature, having a potentially high specific capacitance. They also offer a wider potential range, more electroactivity, and are more environmentally friendly. However, because of its decreased volume expansion and low conductivity, it is difficult to use as a capacitor material. As a result, carbon-based porous films and supports can be employed to produce critical composites to overcome the current shortcoming. These nanoparticle-based materials will have improved electrical conductivity and a large surface area. Graphene oxide (GO) has a high surface area, thermal stability, and porosity. As an electrode material, many types of MnO2/carbon-based materials have been widely used in supercapacitors. Their overall performance is influenced by their construction processes, metal ratios, electrolyte medium, and voltage factors. Microwave technology was chosen as a cost-efficient and effective alternative to expensive and laborious techniques for fabricating MnO2/GO composites. The production procedure of a supercapacitor has been explored in this study using MnO2-GO composite materials. Using the electrochemical deposition process, the nanocomposite materials of MnO2-GO are significantly deposited on the stainless steel (SS) substrate material. Galvanostatic charge-discharge techniques and cyclic voltammetry (CV) analytical methods were used to investigate the storage and cycle ability of supercapacitors. The composite MnO2-GO supercapacitor has a higher electrochemical capacitance based on these findings.
Rapid prototyping of metabolites detection by bacterial biosensors in human fecal samples

Gut metabolites are pivotal mediators of host-microbiome interactions and provide an important window on human physiology and disease. However, current methods to monitor gut metabolites rely on heavy and expensive technologies such as liquid chromatography-mass spectrometry (LCMS). In that context, robust, fast, field-deployable, and cost-effective strategies for monitoring fecal metabolites would support large-scale functional studies and routine monitoring of metabolites biomarkers associated with pathological conditions. Living cells are an attractive option to engineer biosensors due to their ability to detect and process many environmental signals and their self-replicating nature. Here we optimized a protocol for feces processing and gut metabolites detection using bacterial biosensors (bactosensors), enabling rapid evaluation of their operational capacity in these samples. We show that a simple filtration step is enough to remove host microbes and reproducibly obtain a physiological-derived media retaining important characteristics of human feces, such as matrix effects and endogenous metabolites. We measured how fecal samples affect the performance of biosensors for benzoate, lactate, anhydrotetracycline, and bile acids, and found that bactosensors are highly sensitive to fecal matrices. Sensitivity to the matrix is biosensor-dependent but also varies between individuals, highlighting the need for case-by-case optimization for bactosensors operation in feces. Finally, by detecting endogenous bile acids, we demonstrate that bactosensor can be used for metabolites monitoring in feces. This work lays the foundation for the optimization and use of bacterial biosensors for fecal metabolites monitoring. In the future, our method could also allow rapid pre-prototyping of engineered bacteria designed to operate in the gut, with applications to in situ diagnostics and therapeutics.
Sometimes Finding Nothing is Something: Shrinking the Gap between Emerging Bilingual Learners and English Fluent Students (Case in Point)

For United States of America (USA) and other developed countries, science achievement gaps begin to emerge in elementary and primary school. Such gaps between USA student groups typically are connected to socio-economic status (SES) and issues such as students still learning the English language. Through an experimental design, this National Science Foundation funded study explores how integrating the arts into science, technology, engineering, and mathematics (STEM) curriculum and leading with a more STEAM-first approach (e.g., curriculum which integrates science, technology, engineering, arts, and mathematics) might provide more equitable science learning opportunities for elementary or primary grade level students. More specifically, the project’s research efforts seek to also examine how integrating the arts into science instruction might help emerging bilingual (EB) students who are simultaneously learning the English language and science. Although results provide somewhat conflicting findings of statistical significance with small to moderate effect sizes, outcomes provide initial evidence that leading with STEAM science instruction before STEM efforts can be beneficial to early readers, and for EB students this benefit is magnified. As the title of this study suggest, sometimes finding nothing is something.
Factors of Video Directly Observed Therapy Adoption in Malaysia

Remote patient monitoring using mobile devices can be a cost-effective, time-saving solution limiting patient mobility. Direct observation of therapy (DOT) of tuberculosis patients in Malaysia usually involves traveling to the healthcare facility. Due to the contagious nature of the disease, who comes into contact with patients is at risk of developing it. Additionally, DOT is time–consuming and costly for patients. A smartphone application for remote tuberculosis patient monitoring called video directly observed therapy (VDOT) can be a cost-effective and safer way of patient monitoring. However, before implementing this technology, the user readiness assessment helps policymakers' decision-making. This pre-implementation phase study aims to ascertain users' intent to utilize the VDOT app. The current study examines users' readiness using a modified Unified Theory of Acceptance and Use of Technology (UTAUT). The cross-sectional survey took place in Selangor and the federal territory of Kuala Lumpur, Malaysia. A total of 220 questionnaires were delivered to prospective users, including patients and family members. 68% percent of the questioners were deemed usable and were evaluated using SPSS. The study's findings indicate that users intend to adopt the VDOT app for tuberculosis remote monitoring. Performance expectancy, social influence, facilitating conditions, and trust influence users' behavioral intention to adopt the VDOT app in Malaysia.
Regulating Safety at Work: The Recovery of an idea

Abstract Globalisation discourses continue to proliferate, seeping into political and popular consciousness, and in so doing affecting the relative ‘feasibility’ of regulatory options, not least with respect to occupational safety. This observation provides the general context for this paper, which begins by setting out some of the key recent findings of a review of what works with respect to improved occupational safety, and then sets these findings alongside government policies which are running directly opposite to the direction indicated by such research, in an increasing shift away from formal enforcement and towards advice and education. This apparent paradox is partly resolved, it is argued, through a focus on the nature and effects of globalisation discourses which, in short, assign political management of economic actors to the margins, while foregrounding the inevitable primacy of state withdrawal from ‘interference’ in markets. This orthodoxy is then challenged through reference to some of the small but growing body of social scientific work which has examined critically some of the presumed effects of globalisation on nation-state political autonomy — and on this basis the paper argues for an opening up of political agendas regarding what is feasible in terms of the regulation of occupational safety.
Characteristics of successful safety programs

This research was a companion study to an earlier questionnaire study by calling, Smith, and Colin (1975) in which safety program practices of matched pairs of low and high accident rate plants were compared to determine factors that might account for the difference in safety performance. On-site surveys were made of a sample of seven pairs of the questionnaire respondents in order to expand on the results of Colin et al. the on-site surveys resulted in finding similar to the questionnaire study, but reported additional differences in safety program practices that could account for the plant safety performance. The data indicated that the low accident companies differed from their matched high rate partners in the following ways: greater management commitment and involvement in the safety program and safety matters; a more humanistic approach in dealing with employees stressing frequent positive contact and interaction; better employee selection procedures; more frequent use of lead workers to train employees versus supervisors; a much greater degree of housekeeping and general plant cleanliness; better plant environmental qualities; and low turnover and absenteeism among a more stable workforce.
