Syndrome: Spectral analysis for anomaly detection on medical IoT and embedded devices (2018)

Recent advances in embedded and IoT (internet-of-things) technologies are rapidly transforming health-care solutions and we are headed to a future of smaller, smarter, wearable and connected medical devices. IoT and advanced health sensors provide more convenience to patients and physicians. Where physicians can now wirelessly and automatically monitor patient's state. While these medical embedded devices provide a lot of new opportunities to improve the health care system, they also introduce a new set of security risks since they are connected to networks. More importantly, these devices are extremely hardware- and power-constrained, which in turn makes securing these devices more complex. Implementing complex malware detectors or anti-virus on these devices is either very costly or infeasible due to these limitations on power and resources. In this paper, we propose a new framework called SYNDROME for “externally” monitoring medical embedded devices. Our malware detector uses electromagnetic (EM) signals involuntary generated by the device as it executes a (medical) application in the absence of malware, and analyzes them to build a reference model. It then monitors the EM signals generated by the device during execution and reports an error if there is a statistically significant deviation from the reference model. To evaluate Syndrome, we use open-source software to implement a real-world medical device, called a Syringe Pump, on a variety of well-known embedded/IoT devices including Arduino Uno, FPGA Nios II soft-core, and two Linux IoT mini-computers: OlimexA13 and TS-7250. We also implement a control-flow hijack attack on SyringePump and use Syndrome to detect and stop the attack. Our experimental results show that using Syndrome, we can detect the attack for all the four devices with excellent accuracy (i.e. 0% false positive and 100% true positive) within few milliseconds after the attack starts.
3D Scanning of Workpieces with Cooperative Industrial Robot Arms (2016)

This paper describes the realization of a cooperative scanning approach by two industrial robot arms. The basic idea is the distribution of the movements on two robots by one robot handling the sensor and the other one handling the workpiece. Through this approach reachability is improved. In addition, the reference between the workpiece and the grasping robot is included in the scan model. Thus, the resulting model can be used well for subsequent workpiece related machining processes.
Coating Cutting Blades with Thin-Film Metallic Glass to Enhance Sharpness (2019)

In this study, we sought to enhance the cutting properties of the various blades by coating them with Zr- and Fe-based thin film metallic glasses (TFMGs) to a thickness of 234-255 nm via sputter deposition. In oil-repellency/sliding tests on kitchen blades, the sliding angle and friction forces were as follows: bare blades (31.6°) and (35 µN), Ti-coated blades (20.3°) and (23.7 µN), and Z-TFMG coated blades (16.2°) and (19.2 µN). Comparisons were conducted with bare blades and those with a Teflon coating (a low-friction material commonly used for the coating of microtome blades). We also found that the Teflon coating reduced the cutting forces of an uncoated microtome blade by ~80%, whereas the proposed Z-TFMG achieved a ~51% reduction. The Z-TFMG presented no indications of delamination after being used 30 times for cutting; however, the Teflon coating proved highly susceptible to peeling and the bare blade was affected by surface staining. These results demonstrate the efficacy of the TFMG coating in terms of low friction, non-stick performance, and substrate adhesion. The performance of Z-TFMG and F-TFMG was also evaluated in split-thickness skin graft surgery using dermatome blades aimed at elucidating the influence of TFMG coatings on the healing of surgical incisions. When tested repeatedly on hairless skin, the surface roughness of uncoated blades increased by approximately 70%, whereas the surface roughness of TFMG-coated blades increases by only 8.6%. In the presence of hair, the surface roughness of uncoated blades increased by approximately ~108%, whereas the surface roughness of TFMG-coated blades increases by only ~23%. By Day 7, the wounds produced using TFMG-coated blades were noticeably smaller than those produced using uncoated blades, and these effects were particularly evident in hairy samples. This is a clear demonstration of the efficacy of TFMG surface coatings in preserving the cutting quality of surgical instruments.
Scalable production of graphene via wet chemistry: progress and challenges (2014)

Although enormous scientific progress has been made in the application of graphene and its related materials, the cost-effective and scalable production of graphene still holds the key to its commercialization. If this aspect cannot be successfully addressed, it may eventually struggle for widespread use, such as has occurred for its allotrope, the carbon nanotubes. Ease of graphene production is especially important if it is to be used in bulk applications such as energy storage in automobiles where the large scale and low cost production of the active materials is required. Fortunately, graphene can be produced not only from a cheap and abundant source (graphite), but also can be produced using a variety of low cost methods. This focus review article will examine three promising, scalable methods of graphene production, namely the graphite oxide, liquid-phase exfoliation (LPE) and electrochemical routes, with focus on their recent progress and remaining challenges. The perspective on these routes will be mainly taken from the industrial viewpoint, thus highlighting the pressing issues for graphene commercialization. Some of the main concerns regarding the quality or crystallinity of the graphene sheet produced from such methods and the importance of a comprehensive evaluation of the final bulk graphene materials will also be discussed.
MATHEMATICAL PRELIMINARIES (1993)

1.0 INTRODUCTION. Some relevant mathematical results are collected in this chapter. These results find a wide application within the realm of analysis, synthesis and optimization of mechanisms. Often, rigorous proofs are not provided; however a reference list is given at the end of the chapter, where the interested reader can find the required details.
Mutually exclusive binding of peptide and invariant chain to major histocompatibility complex class II antigens (1994)

The invariant chain is a membrane protein associated with the major histocompatibility complex class II antigens both intra- and extracellularly. The extracellular portion of the human invariant chain (Ii) was expressed in Escherichia coli as a fusion protein with a polyhistidine tail and purified by metal affinity chromatography. The recombinant Ii was used as a ligand to probe binding to the cell surface of Chinese hamster ovary cells stably transfected with human class II alpha and beta genes of the DR4 isotype. We show that recombinant Ii inhibits peptide loading on class II polypeptides and also the converse; the presence of peptide in the antigen groove prevents binding of fluorescein-conjugated Ii. Moreover, blocking of Ii binding by peptide did not require a transition of the class II dimers to an SDS-stable state. A monoclonal antibody, L243, known to bind to (or close to) the peptide pocket of the class II molecule likewise blocked Ii-fluorescein binding. Further, we investigated whether or not the Ii, a variety of bacterial superantigens or the CD4 molecule, have overlapping binding sites on the class II heterodimer. Of the class II ligands tested, reduced binding was detected for the Staphylococcus superantigen type SEB on cells precincubated with soluble Ii while the binding of the other ligands was either unchanged or marginally changed. These data clarify by a direct biochemical approach the binding characteristics of Ii in comparison with other class II ligands.
Direct binding of F‐actin to ponticulin, an Integral plasma membrane glycoprotein (1991)

We have developed an 125I-labeled F-actin blot overlay assay for the identification of F-actin-binding proteins after transfer to nitrocellulose from SDS-polyacrylamide gels. Two major F-actin-binding proteins from Dictyostelium discoideum, a cytoplasmic 30 kDa protein and a 17 kDa integral membrane protein, and two minor membrane polypeptides of 19 kDa and 15 kDa were detected by this method. Using F-actin affinity and immunoaffinity chromatography, the 17 kDa polypeptide was identified as ponticulin, a previously described actin-binding glycoprotein from D. discoideum plasma membranes (Wuestehube, L.J., and Luna, E.J., [1987]: J. Cell Biol. 105:1741-1751). The binding of F-actin to ponticulin on blots is specific because unlabeled F-actin competes with 125I-labeled F-actin and because G-actin does not bind. Nitrocellulose-bound ponticulin displays binding characteristics similar to those of purified plasma membranes in solution, e.g., F-actin binding is sensitive to high salt and to elevated temperatures. Under optimal conditions, 125-I-labeled F-actin blot overlays are at least as sensitive as are immunoblots with an antibody specific for ponticulin. When blotted onto nitrocellulose after 2-D gel electrophoresis, all isoforms of ponticulin and of the 19 kDa and 15 kDa polypeptides appear to bind F-actin in proportion to their abundance. Thus the actin-binding activies of these proteins do not appear to be regulated by modifications that affect isoelectric point. However, the actin-binding activity of nitrocellulose-bound ponticulin is diminished when the protein is exposed to reducing agents, suggesting an involvement of disulfide bond(s) in ponticulin function. The 125I-labeled F-actin blot overlay assay also may enable us to identify F-actin-binding proteins in other cell types and should provide a convenient method for monitoring the purification of these proteins.
Mask Assisted Object Coding with Deep Learning for Object Retrieval in Surveillance Videos (2014)

Retrieving visual object from a large-scale video dataset is one of multimedia research focuses but a challenging task due to imprecise object extraction and partial occlusion. This paper presents a novel approach to efficiently encode and retrieve visual objects, which addresses some practical complications in surveillance videos. Specifically, we take advantage of the mask information to assist object representation, and develop an encoding method by utilizing highly nonlinear mapping with a deep neural network. Furthermore, we add some occluded noise into the learning process to enhance the robustness of dealing with background noise and partial occlusions. A real-life surveillance video data containing over 10 million objects are built to evaluate the proposed approach. Experimental results show our approach significantly outperforms state-of-the-art solutions for object retrieval in large-scale video dataset.
User expectations for mobile mixed reality services: an initial user study (2009)

Mixed reality, i.e. the integration and merging of physical and digital worlds, has become an integral part of the ubicomp research agenda. Often, however, in development of first technology concepts and prototypes, the expectations of potential users are not considered, and the development easily becomes technology-driven. To understand the expectations and needs of potential users of future mobile mixed reality (MMR) services, we conducted altogether five focus group sessions with varying user groups. We investigated the early impressions and expectations of MMR as a technology by evaluating various usage scenarios. Based on this initial study, we found relevance issues (what information to receive, how and when) and the reliability of MMR information to be the most salient elements that were anticipated to affect the overall user experience. In mobile and busy situations the MMR information content has to be something that is very important or useful for the user, especially if receiving the information or interacting with it draws the user's attention away from the tasks executed in the real world.
Predicting physiological developments from human gait using smartphone sensor data (2017)

Coronary artery disease, heart failure, angina pectoris and diabetes are among the leading causes of morbidity and mortality over the globe. Susceptibility to such disorders is compounded by changing lifestyles, poor dietary routines, aging and obesity. Besides, conventional diagnostics are limited in their capability to detect such pathologies at an early stage. This generates demand for automatic recommender systems that could effectively monitor and predict pathogenic behaviors in the body. To this end, we propose human gait analysis for predicting two important physiological parameters associated with different diseases, body mass index and age. Predicting age and body mass index by actively profiling the gait samples, could be further used for providing suitable healthcare recommendations. Existing strategies for predicting age and body mass index, however, necessitate stringent experimental settings for achieving appropriate performance. For instance, precisely recorded speech signals were recently used for predicting body mass indices of different subjects. Similarly, age groups were predicted by recording gait samples from on-body and wearable sensors. Such specialized methods limit active and convenient profiling of human age and body mass indices. We address these issues, by introducing smartphone sensors as a means for recording gait signals. Using on-board accelerometer and gyroscope helps in developing easy-to-use and accessible systems for predicting body mass index and age. To empirically show the effectiveness of our proposed methodology, we collected gait samples from sixty-three different subjects that were classified in body mass index and age groups using six well-known machine learning classifiers. We evaluated our system using two different windowing operations for feature extraction, namely Gaussian and Square.
The surface glycoproteins of human skin fibroblasts detected after electrophoresis by the binding of peanut (<i>Arachis hypogaea</i>) agglutinin and <i>Ricinus communis</i> (castor-bean) agglutinin I. (1982)

A new methodology was developed to study the cell-surface glycoproteins of cultured human skin fibroblasts. This was based on the binding of a variety of biotinyl-lectins to nitrocellulose electrophoretic transfers of total fibroblast lysates after separation in sodium dodecyl sulphate/polyacrylamide gels, followed by reaction with avidin-biotinyl-peroxidase complexes and detection with 3,3'-diaminobenzidine. The technique proved to be very sensitive and a large number of glycoproteins were detected by binding of concanavalin A and wheat-germ agglutinin. Binding of peanut agglutinin and to a lesser extent of Ricinus communis agglutinin I were found to be dependent on prior removal of sialic acid residues from the glycoproteins. Since by treatment of intact viable cells with neuraminidase only external sialic acid residues were removed, peanut agglutinin and Ricinus communis agglutinin I could thus be utilized for selective detection of cell-surface glycoproteins. Also, because peanut agglutinin was known to bind preferentially to oligosaccharides of the O-glycosidic type, and Ricinus communis agglutinin I to those of the N-glycosidic type, the two lectins were complementary in displaying the surface glycoproteins and in providing information about their oligosaccharide composition.
Identification of ergosta‐6(7),8(14),25(27)‐trien‐3β‐ol and ergosta‐5(6),7(8),25(27)‐trien‐3β‐ol, two new steroidal trienes synthesized by<i>Prototheca wickerhamii</i> (1991)

Abstract Ergosta‐6(7),8(14),25(27)‐trien‐3β‐ol, ergosta‐5(6),7(8),25(27)‐trien‐3β‐ol, ergosterol, 25(27)‐dehydroergosterol (protothecasterol), ergosta‐7,25(27)‐dien‐3β‐ol and ergost‐7‐en‐3β‐ol have been isolated from cells of Prototheca wickerhamii . The structures of the compounds have been determined in stereochemical detail by a series of chromatographic and spectral techniques. The results are interpreted to imply that whereas P. wickerhamii is non‐photosynthetic and yeast‐like in appearance and synthesizes ergosterol, the organism can be biochemically distinguished from yeast and considered an alga in part through the detection of other sterols described herein, notably those with Δ 25(27) side chains.
Adipose Tissue Engineering from Adult Human Stem Cells: A New Concept in Biosurgery (2010)

Current autologous fat grafting technique suffers from the drawbacks of donor site morbidity and, more importantly, significant resorption of the grafted fat. Adipose tissue engineering using adult human stem cells has been found to overcome the shortcomings of autologous fat grafting in reconstructing facial defects. Mesenchymal stem cells that can self-renew and differentiate into mature adipocytes have been used to generate adipose tissue, in both in vitro and in vivo cell transplantation studies. However, long-term maintenance of the shape and dimension of the produced adipose tissue remains a challenge, even in tissue engineering with cell transplantation. The choice of appropriate scaffolds to promote stem cell adhesion, proliferation, and differentiation is essential for successful adipogenesis. Recent advances in nanotechnology allow the development of nanostructured scaffolds with a cellular environment that maximally enhances not only cell expansion but also the neovascularization that is crucial for long-term maintenance of cell volume. Cell homing is a technique that actively recruits endogenous host stem cells into a predefined anatomic location for the desired tissue generation. Bypassing ex vivo cell manipulation, the cell homing technique eliminates donor site morbidity and rejection, reducing the regulation issue in clinical translation. Mao et al. introduced the concept of biosurgery, which combined nanostructured scaffolds and growth factor biocues, with or without cell transplantation, for successful de novo adipogenesis in restoring facial defects. Important questions, such as the necessity of cell transplantation in scaling up the size of engineered adipose tissue, need to be answered with further studies. However, the era of biosurgery replacing conventional treatments such as biologically inactive filler injections and alloplastic implants appears to be in the near future.
Predicting Hyperacusis in Tinnitus Patients (2007)

The goal of this study was to develop a model that predicts whether tinnitus patients would report hyperacusis based upon their audiometric thresholds and loudness discomfort levels (LDLs), measured at 1000, 2000, 4000, and 8000 Hz. Follow-up LDLs subsequent to tinnitus retraining therapy (TRT) were used to predict hyperacusis subsequent to treatment. Pretreatment and TRT follow-up audiometric thresholds and LDLs were analyzed for a group of 68 tinnitus patients who self-reported sound tolerance complaints and a group of 58 tinnitus patients who denied sound tolerance problems. A logistic regression model was implemented to determine which of the eight audiological measures (i.e., four threshold and four LDL measures) were essential in predicting the hyperacusis or tinnitus-only categorization. Predictions from the logistic regression model are compared with three versions of a published categorization scheme. The success of each model varied depending on the hearing-loss configuration, with poorest performance for sloping hearing losses. The logistic regression model was the best model overall. The logistic regression model predicted improvement for 54 of 68 (79%) self-reported hyperacusis patients following TRT treatment. The logistic regression model improves the prediction of hyperacusis in tinnitus patients and successfully predicts improvement in the majority of tinnitus patients following TRT treatment.
Immunostimulant Agents from Andrographis paniculata (1993)

EtOH extract and purified diterpene andrographolides of Andrographis paniculata (Acanthaceae) induced significant stimulation of antibody and delayed type hypersensitivity (DTH) response to sheep red blood cells (SRBC) in mice. The plant preparations also stimulated nonspecific immune response of the animals measured in terms of macrophage migration index (MMI) phagocytosis of 14C-leucine labelled Escherichia coli and proliferation of splenic lymphocytes. The stimulation of both antigen specific and nonspecific immune response was, however, of lower order with andrographolide than with the EtOH extract, suggesting thereby that substance(s) other than andrographolide present in the extract may also be contributing towards immunostimulation.

Porous silicon as a sacrificial layer used in rf MEMS (2001)

This paper designs a process to prepare RF-MEMS using porous silicon (PS) as a sacrificial layer. The details of the process are discussed, such as the influences of H<SUB>2</SUB>SO<SUB>4</SUB>, H<SUB>3</SUB>PO<SUB>4</SUB>, and HF on the PS layer. KOH and TMAH solutions are used to remove the PS layer through small etching holes and to reduce the probability of the potential film damage, ethanol is used to dilute the KOH and TMAH solution. After the process, a suspended thin SiO<SUB>2</SUB> film as large as 2x2mm<SUP>2</SUP> is successfully achieved and the maximum lateral distance between the small etching holes is 540micrometers . Finally, two application examples are given.
