The IIoT devices to cloud gateway design and implementation based on microcontroller for real-time monitoring and control in automation systems (2017)

This papers presents a design and implementation technique to develop an IIoT gateway that works as Device-to-Cloud gateway. The gateway is specifically designed and implemented based on industrial automation systems. It is designed to support traditional sensors and actuators that operate on standard current and voltage values (4-20mA, 0-12V or 0-24V). Also it can communicate to Modbus devices using Modbus-RTU protocol. With these design features, the proposed system can be used in many industrial automation applications. To achieve the real-time ability of the system, the WebSocket protocol is implemented in both microcontroller (MCU) and Cloud system. The IIoT gateway is implemented on a 16-bit MCU. The MCU is preprogrammed with special firmware. The firmware is designed and implemented based on real-time multitasking and interrupt-driven to be sure it can serve all required tasks on time. To make the MCU can communicate to the Cloud system, the WiFi module that supports TCP/IP protocol is connected to the MCU. To fully evaluate and examine the proposed system, four channels of sensors, four channels of actuators, and six Modbus devices (Power meters) are used to construct an experimental system. There are three web-applications developed to examine the data communication between the IIoT gateway and the Cloud system. The experimental results show that the proposed IIoT gateway can exchange desired data to the Cloud system, back and forth as real-time data streaming.
A Review on the Traditional Chinese Medicinal Herbs and Formulae with Hypolipidemic Effect (2014)

Hyperlipidemia, characterized by the abnormal blood lipid profiles, is one of the dominant factors of many chronic diseases such as diabetes, obesity, and cardiovascular diseases (CVD). For the low cost, effectiveness, and fewer side effects, the popularity of using traditional Chinese medicine (TCM) to handle hyperlipidemia is increasing and its role in health care has been recognized by the public at large. Despite the importance of TCM herbs and formulations, there is no comprehensive review summarizing their scientific findings on handling hyperlipidemia. This review summarizes the recent experimental and clinical results of nine representative single Chinese herbs and seven classic TCM formulae that could improve lipid profiles so as to help understand and compare their underlying mechanisms. Most of single herbs and formulae demonstrated the improvement of hyperlipidemic conditions with multiple and diverse mechanisms of actions similar to conventional Western drugs in spite of their mild side effects. Due to increasing popularity of TCM, more extensive, well-designed preclinical and clinical trials on the potential synergistic and adverse side effects of herb-drug interactions as well as their mechanisms are warranted. Hyperlipidemic patients should be warned about the potential risks of herb-drug interactions, particularly those taking anticoagulants and antiplatelet drugs.
The Placenta Theory and the Origin of Infantile Hemangioma (2007)

The pathogenesis of infantile hemangioma is unknown. In recent years, much of the focus has been placed at identifying the cell type(s) responsible for tumor initiation. New discoveries in infantile hemangioma suggest an involvement of progenitor cells in the pathogenesis of this vascular tumor. Both embryonic and extra-embryonic tissues have been postulated as potential sources for these progenitor cells. This review focuses on the placental theory, which proposes that a fetal placental progenitor is the cell type of origin for infantile hemangioma. Special emphasis will be placed on placental vasculogenesis and the presence and transit of placental progenitor cells during gestation.

Parallel Scatter Search Algorithms for Exam Timetabling (2011)

University exam timetabling refers to scheduling exams into predefined days, time periods and rooms, given a set of constraints. Exam timetabling is a computationally intractable optimization problem, which requires heuristic techniques for producing adequate solutions within reasonable execution time. For large numbers of exams and students, sequential algorithms are likely to be time consuming. This paper presents parallel scatter search meta-heuristic algorithms for producing good sub-optimal exam timetables in a reasonable time. Scatter search is a population-based approach that generates solutions over a number of iterations and aims to combine diversification and search intensification. The authors propose parallel scatter search algorithms that are based on distributing the population of candidate solutions over a number of processors in a PC cluster environment. The main components of scatter search are computed in parallel and efficient communication techniques are employed. Empirical results show that the proposed parallel scatter search algorithms yield good speed-up. Also, they show that parallel scatter search algorithms improve solution quality because they explore larger parts of the search space within reasonable time, in contrast with the sequential algorithm.
Effects of Monoacylglycerols on the Cold Flow Properties of Biodiesel (2012)

Abstract Biodiesel is a renewable alternative fuel made from plant oils and animal fats that may be burned in a compression–ignition (diesel) engine. It is composed of mono‐alkyl fatty acid esters made from plant oils or animal fats mainly by transesterification with methanol or ethanol. This process leaves behind small concentrations of minor constituents including monoacylglycerols (MAG). Saturated MAG have low solubility in biodiesel and may form solid residues during storage in cold weather. Soybean oil‐fatty acid methyl esters (SME) were mixed with up to 1.0 mass% MAG to evaluate the effects on cloud point (CP), freezing point (FP), cold filter plugging point (CFPP), and wax appearance point (WAP). Differential scanning calorimetry (DSC) results showed that MAG with only 27.6 mass% total long chain (C16–C18) saturated fatty acid content had melting transitions between 54 and 59.0 °C. Furthermore, DSC analysis indicated that pure monoolein may be problematic with respect to melting transitions between 25.4 and 33.4 °C. Solubility data for SME–MAG mixtures indicated a broad transition temperature range from solid at low temperature to liquid at temperatures exceeding 60 °C. Increasing the added MAG content from 0.10 to 1.0 mass% increased both CP and FP. Cold filter plugging point demonstrated higher sensitivity than CP or FP at added MAG content below 0.10 mass%, though it was not affected by increasing MAG concentration above 0.50 mass%. Wax appearance point showed no effects until added MAG content exceeded 0.25 mass%. Kinematic viscosity measured at 5 °C similarly showed no effects until added MAG concentration exceeded 0.20 mass%. Specific gravity at 15.6 °C and refractive index at 25 °C were not greatly affected by added MAG except at concentrations greater than 0.10 mass%.
Antizyme Inhibitor 2 (AZIN2/ODCp) Stimulates Polyamine Uptake in Mammalian Cells (2008)

One of the processes that regulate intracellular levels of polyamines in mammalian cells is polyamine uptake. We have measured polyamine uptake in COS7 cells for putrescine, spermidine, and spermine, obtaining K(m) values of 4.5, 1.0, and 0.8 mum, respectively. Treatment of nonconfluent cells with cycloheximide stimulated polyamine uptake and prevented the inhibitory effect found in cells preloaded with polyamines, suggesting the existence of a feedback repression mechanism mediated by antizymes. Transient transfected cells with mutated antizyme forms of AZ1, AZ2, and AZ3, which do not require frameshifting, showed a total blockade of polyamine uptake. Transfection of COS7 cells with mouse or human AZIN2, a novel member of the antizyme inhibitor family, recently characterized by our group, markedly stimulated polyamine uptake and counteracted the action of any of the three antizymes in co-transfected cells. The stimulatory effect of AZIN2 on polyamine uptake was abrogated when the putative antizyme binding sequence, formed by residues 117-140 in AZIN2, was deleted. Real time reverse transcription-PCR analysis of antizyme inhibitor transcripts revealed that in brain and testes AZIN2 is more expressed than AZIN1, especially in the testes where the relative expression was about 25-fold higher. Collectively, our results clearly indicate that AZIN2 affects polyamine homeostasis not only by increasing ornithine decarboxylase activity but also by stimulating polyamine uptake, through negating the inhibitory effect of the antizymes. This finding may have physiological relevance, mostly in testes where AZ3 and AZIN2 are mainly expressed.
Miglitol (Bay m 1099) has no extraintestinal effects on glucose control in healthy volunteers (1996)

In this double-blind, cross-over, placebo-controlled, randomized study, possible extraintestinal effects of miglitol, an absorbable α-glucosidase inhibitor, were investigated. Sixteen healthy male volunteers underwent two 75 g oral glucose tolerance tests with concomitant administration of miglitol or placebo. Peak and post-peak areas under the curve values for blood glucose, serum insulin and serum C-peptide after miglitol were not different from those found after placebo. The post-peak AUC-ratio (AUC (peak, 180 min) on miglitol/AUC (peak, 180 min) on placebo) was for glucose 1.15 (CI 0.94–1.40, P=0.16), for insulin 1.12 (CI 0.95–1.33, P=0.17) and for C-peptide 0.98 (CI 0.81–1.18, P=0.82). It is concluded that miglitol exerts no clinically relevant extraintestinal effects on glucose control.
The Horn Fly: Methoprene in Drinking Water of Cattle for Control12 (1975)

Devices were constructed to meter 0.34 mg of methoprene/liter of water automatically into the troughs of drinking water of a 350-animal herd of cattle. The effect on the population of Haematobia irritans (L.), as determined by bioassay of fresh manure collected at intervals from the pasture, was complete inhibition of development of adult horn flies. As a result, the number of horn fly eggs on manure droppings in the pasture declined from an avg 75 to 13 eggs/dropping, and the number of flies was reduced from an average 360 to 7/animal. The untreated group, 12 animals, maintained an avg 300 flies/animal during the initial 5 wk of the 6-wk test. However, all water in the pasture was not treated, and marked sterile flies released on another herd 16 mi distant were found on test animals. Thus, reinfestation was occurring, both from within and outside the test area throughout the test period.
Suppressors of the egg-laying defective phenotype of <i>sel-12</i> presenilin mutants implicate the CoREST corepressor complex in LIN-12/Notch signaling in <i>C. elegans</i> (2002)

Presenilin is an essential component of the LIN-12/Notch signaling pathway and also plays a critical role in the genesis of Alzheimer's disease. Previously, a screen for suppressors of the egg-laying defective phenotype caused by partial loss of presenilin activity in Caenorhabditis elegans identified a number of new spr genes that are potentially involved in the regulation of LIN-12/Notch signaling or presenilin activity. Here we report the molecular identity of two spr genes, spr-1 and spr-5. Our genetic analysis indicates that loss of spr-1 elevates lin-12/Notch gene activity in many different cell fate decisions, suggesting that spr-1 is a negative regulator of LIN-12/Notch signaling. Sequence analysis revealed that spr-1 is an ortholog of human CoREST, a known corepressor. SPR-1 is localized to the nucleus and acts in a cell-autonomous manner; furthermore, human CoREST can substitute for SPR-1 in C. elegans. We also show that spr-5 encodes a homolog of p110b, another known member of the CoREST corepressor complex. Our results suggest that the CoREST corepressor complex might be functionally conserved in worms, and we discuss the potential role of SPR-1 and SPR-5 in the repression of transcription of genes involved in, or downstream of, LIN-12/Notch signal transduction.
A web based virtual environment as a connection platform between people and IoT (2016)

Smart objects are present in our cities everywhere, thus it is becoming more and more necessary to have a connection platform, not only capable to make those objects talk with each other, but to present the results of their functions also to the citizens/users. Objective of this paper is the definition and development of a model that represents a connection and interaction layer between smart objects and people. In particular, we propose an immersive virtual platform, able to engage endusers and let people be aware of the where, what and how factors: where smart objects are deployed in the city, what functionalities/data they offer, and how those data represent context for the urban areas. To prove this particular model, we developed a prototypical Virtual Environment of Things (VEoT), within an immersive 3D environment in which the user can explore the virtualized urban area and interact with the available smart objects through gestures and affordable VR devices. The VEoT is fed by real-time data produced by a multi-protocol sensing middleware that simplifies the interaction with physical devices through high-level (RESTful) APIs. Paying attention to interconnection of people and things, this prototype will empower final users with engaging tools in order to enhance the fruition of the IoT paradigm.
On the influence of a fabrication imperfection on the normal acceleration sensitivity of contoured quartz resonators with rectangular supports (2002)

It is shown that the normal acceleration sensitivity of contoured quartz resonators with rectangular supports vanishes when the centers of the mode shape and support rectangle coincide. This result is essentially a consequence of symmetry and applies to many other shapes. Since it is extremely difficult to realize this situation in practice, an analysis of the influence of an offset of the centers on the normal acceleration sensitivity is performed. The biasing deformation is determined by means of a variational approximation procedure using the variational principle with all natural conditions for anisotropic static flexure. The very important accompanying strains which vary quadratically across the thickness are determined recursively. The resulting flexural biasing states are used in the existing perturbation equation along with the equivalent trapped energy mode shapes of the contoured resonators to calculate the normal acceleration sensitivities. It is shown that for small offsets the acceleration sensitivity increases linearly with offsets and orientations for which this effect is minimized.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Deformation of the Human Mandible During Simulated Tooth Clenching (1994)

Localized corpus and dental arch distortions measured directly on human and animal mandibles suggest complex deformation patterns at other mandibular sites during functional loading. To describe these, we simulated selected static bites on a three-dimensional finite element computer model of the human jaw. Five clenching tasks were modeled: intercuspal position, left group function, left group function plus balancing contact, incisal clenching, and right molar clenching. Under conditions of static equilibrium and within the limitations of the current modeling approach, the human jaw deforms elastically during symmetrical and asymmetrical clenching tasks. This deformation is complex, and includes the rotational distortion of the corpora around their axes. In addition, the jaw also deforms parasagittally and transversely. The degree of distortion depended on each clenching task, with actual deformations being relatively small and ranging from 0.46 mm to 1.06 mm for the tasks modeled when all sites were taken into account. The predicted overall narrowing of the dental arch is consistent with clinical reports in the literature during similar, although not identical, static jaw function. The predicted regional deformations of the upper condylar surfaces imply differential loading at their upper surfaces. Although still constrained to forceful static biting conditions, the simulated mandibular and dental arch distortions should be taken into consideration in the design and testing of prosthetic devices in the lower jaw.
Common design structure discovery from CAD models (2009)

This paper presents a method to solve the problem of common design structure discovery from a large number of CAD models. First, a CAD model is transformed into a face adjacency graph (FAG) and each node of FAG is mapped to a point in two-dimensional plane after representing face shape information with two coordinates. So the shapes of models are directly compared through the point coordinates of FAGs' nodes. Thus, the common design structures are just the frequent appearing subgraphs of FAGs. Second, we develop an algorithm to discovery frequent subgraphs of FAGs. The main steps of the algorithm include: (1) frequent candidate subgraph generation based on merging of last discovered frequent subgraphs; (2)subgraph matching with graph descriptive code. The experiment shows a reasonable result of the discovered common design structures with our approach.

Portable Radar-Driven Microwave Sensor for Intermittent Glucose Levels Monitoring (2020)

In this study, a portable prototype of a planar microwave sensor is proposed for intermittent glucose level monitoring. The sensor element basically consists of four distinct hexagonal-shaped complementary split ring resonators (CSRRs) configured in the honey-cell pattern and fabricated on an FR4 dielectric substrate. The CSRRs are coupled via microstrip transmission line to a radar system operating in the ISM band 2.4-2.5 GHz. The integrated sensor shows a remarkable detection sensitivity for the diabetes-spectrum glucose levels dissolved in the blood mimicking aqueous solutions. This is demonstrated by the raw data collected by the radar receiving channel, which shows a clear trend following the variations in glucose levels.
Carbohydrate Supplementation and Resistance Training (2003)

There is a growing body of evidence suggesting that the performance of resistance-training exercises can elicit a significant glycogenolytic effect that potentially could result in performance decrements. These decrements may result in less than optimal physiological adaptations to training. Currently some scientific evidence suggests that carbohydrate supplementation prior to and during high-volume resistance training results in the maintenance of muscle glycogen concentration, which potentially could result in the maintenance or increase of performance during a training bout. Some researchers suggest that ingesting carbohydrate supplements prior to and during resistance training may improve resistance-training performance. Additionally the ingestion of carbohydrates following resistance exercise enhances the re-synthesis of muscle glycogen, which may result in a faster time of recovery from resistance training, thus possibly allowing for a greater training volume. On the basis of the current scientific literature, it may be advisable for athletes who are performing high-volume resistance training to ingest carbohydrate supplements before, during, and immediately after resistance training.
A New Technique for Intraoperative Reduction of Occipitocervical Instability (2010)

We achieved intraoperative reduction of occipitocervical instability through a purely posterior approach. This technique adds a tool to the armamentarium of techniques used for the treatment of occipitocervical instability.
Use of complementary health practices by prostate carcinoma patients undergoing radiation therapy (2000)

Patients undergoing radiation therapy for prostate carcinoma frequently rely on complementary health practices not prescribed by their treating physicians. Patients who do so tend to have higher education and income levels and continue their complementary practices during the conventional treatment. As the health implications of these practices are unclear, further research is clearly needed.
Low-frequency narrow-band acoustic filter with large orifice (2013)

Conventional means of attenuating airborne sound usually require blocking the air medium with a solid material. By exploiting properties of membrane-type acoustic metamaterials (MAMs), we demonstrate large transmission loss to be achievable across a sizable orifice through which air can freely flow. We find that interaction of resonating field of the MAMs with the continuous sound field passing through the orifice is responsible for such phenomenon. The narrow-band characteristic of this effect can be used for acoustic filtering of noise with a particular narrow frequency band.
Steroidal, Aldosterone Antagonists: Increased selectivity of 9α,11‐epoxy derivatives (1997)

Abstract In the search for aldosterone antagonists with an optimal activity profile, twelve 9α, 11‐epoxy‐steroids were prepared and compared with their 9α, 11α ‐unsubstituted analogues in terms of steroid receptor binding in vitro and electrolyte excretion in vivo. Substitution of the parent structures by an epoxy group at positions 9α, 11 resulted in marginal effects on mineralocorticoid receptor binding and electrolyte excretion, but greatly reduced androgen and gestagen receptor binding. This finding is reflected in the largely lacking unwanted anti‐androgenic and gestagenic side effects in animal models of the three most interesting 9α, 11 ‐epoxy‐spirolactones 4 (CGP 33033), 18 (CGP 29245), and 25 (CGP 30083).
Can logic simulators handle bidirectionality and charge sharing? (2002)

A modeling technique that allows the use of the relevant information from a transistor-level interconnection database to drive a logic simulator or a fast hardware accelerator is introduced. A bidirectional element is split into two unidirectional elements tied together with the help of bus elements. Transmission gate and bus models which use the device and node strength information are presented. Realistic examples are used to illustrate that the method leads to a correct simulation.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
A novel technique for programmed generation of multifrequency composite sinusoids (1978)

Test signals consisting of a set of composite sinusoids have found increasing application recently in the non-linear control system testing field. This paper presents a new approach to the implementation of a multifrequency signal generator capitalizing on recent advances in digital techniques. The instrument generates N sinusoids of programmable relative frequency over a very wide dynamic range, in excess of 10−4to 104Hz. Relative phase shift and amplitude ratio are also programmable. The new technique makes possible relative frequency jitter of zero as well as identical and low noise content for all N sinusoids. Extensive simulation studies have fully established zero relative phase error, and zero relative harmonic ratio error; both being prime conditions for accurate multifrequency test signals.
