Authorized Traffic Controller Hand Gesture Recognition for Situation-Aware Autonomous Driving

Ashutosh Mishra, Jinhyuk Kim, Jaekwang Cha, Dohyun Kim, Shiho Kim

An authorized traffic controller (ATC) has the highest priority for direct road traffic. In some irregular situations, the ATC supersedes other traffic control. Human drivers indigenously understand such situations and tend to follow the ATC; however, an autonomous vehicle (AV) can become confused in such circumstances. Therefore, autonomous driving (AD) crucially requires a human-level understanding of situation-aware traffic gesture recognition. In AVs, vision-based recognition is
more &raquo; ... desirable because of its suitability; however, such recognition systems have various bottlenecks, such as failing to recognize other humans on the road, identifying a variety of ATCs, and gloves in the hands of ATCs. We propose a situation-aware traffic control hand-gesture recognition system, which includes ATC detection and gesture recognition. Three-dimensional (3D) hand model-based gesture recognition is used to mitigate the problem associated with gloves. Our database contains separate training and test videos of approximately 60 min length, captured at a frame rate of 24 frames per second. It has 35,291 different frames that belong to traffic control hand gestures. Our approach correctly recognized traffic control hand gestures; therefore, the proposed system can be considered as an extension of the operational domain of the AV.

<span title="2020-08-29">2020</span> <i title="MDPI AG"> <a target="_blank" rel="noopener" href="https://fatcat.wiki/container/jdgqfwsfhzegdhmzc3cgj3t7jy" style="color: black;">Nanomaterials</a> </i> &nbsp;
This study demonstrates the use of perovskite solar cells for fabrication of self-charging lithium-ion batteries (LIBs). A LiFePO4 (LFP) cathode and Li4Ti5O12 (LTO) anode were used to fabricate a LIB. The surface morphologies of the LiFePO4 and Li4Ti5O12 powders were examined using field emission scanning electron microscopy. The structural properties of the two powders were investigated using X-ray diffraction. The electrochemical properties of the LiFePO4-Li and Li4Ti5O12-Li half cells and of
more &raquo; ... the full cell were investigated. The LiFePO4-Li4Ti5O12 full cell showed an excellent Coulombic efficiency of 99.3% after 100 cycles. CH3NH3PBI3 (MAPbI3) perovskite solar cells (PSCs) were fabricated using a spin coating technique. A single PSC showed a power conversion efficiency of 12.95%. In order to develop a self-charging system for LIBs, four single PSCs connected in series were used as an LFP-LTO battery. The integrated PSC system showed a power conversion efficiency of 12.44%. The PSC-LIB coupled device showed excellent overall self-charging conversion and a storage efficiency of 9.25%.

HER2 signaling regulates HER2 localization and membrane retention

Jaekwang Jeong, Wonnam Kim, Lark Kyun Kim, Joshua VanHouten, John J. Wysolmerski, Aamir Ahmad
<span title="2017-04-03">2017</span> <i title="Public Library of Science (PLoS)"> <a target="_blank" rel="noopener" href="https://fatcat.wiki/container/s3gm7274mfe6fcs7e3jterqlri" style="color: black;">PLoS ONE</a> </i> &nbsp;
ErbB2/HER2/Neu is a receptor tyrosine kinase that is overexpressed in 25-30% of human breast cancers, usually associated with amplification of the ERBB2 gene. HER2 has no recognized ligands and heterodimers between HER2 and EGFR (ErbB1/HER1) or HER2 and ErbB3/HER3 are important in breast cancer. Unlike other ErbB family members, HER2 is resistant to internalization and degradation, and remains at the cell surface to signal for prolonged periods after it is activated. Although the mechanisms
more &raquo; ... rlying retention of HER2 at the cell surface are not fully understood, prior studies have shown that, in order to avoid internalization, HER2 must interact with the chaperone, HSP90, and the calcium pump, PMCA2, within specific plasma membrane domains that protrude from the cell surface. In this report, we demonstrate that HER2 signaling, itself, is important for the formation and maintenance of membrane protrusions, at least in part, by maintaining PMCA2 expression and preventing increased intracellular calcium concentrations. Partial genetic knockdown of HER2 expression or pharmacologic inhibition of HER2 signaling causes the depletion of membrane protrusions and disruption of the interactions between HER2 and HSP90. This is associated with the ubiquitination of HER2, its internalization with EGFR or HER3, and its degradation. These results suggest a model by which some threshold of HER2 signaling is required for the formation and/or maintenance of multi-protein signaling complexes that reinforce and prolong HER2/EGFR or HER2/HER3 signaling by inhibiting HER2 ubiquitination and internalization. obligate heterodimer and preferred binding partner with the other ErbB family receptors [1, 3] . While high levels of HER2 in cancer cells can give rise to homodimers that activate signaling, heterodimers between HER2 and EGFR (ErbB1/HER1) or HER2 and ErbB3/HER3 appear to be particularly important in breast cancer [1, 3, [6] [7] [8] [9] . In contrast to other ErbB family members, HER2 is resistant to internalization and degradation, and remains at the cell surface to signal for prolonged periods after it is activated [10] [11] [12] [13] [14] [15] . Although the mechanisms underlying retention of HER2 at the cell surface are not fully understood, this property of the receptor contributes to its ability to transform cells [7, 10, 13] . Prior studies have shown that HER2 must interact with the chaperone, HSP90, and the calcium pump, plasma membrane calcium ATPase2 (PMCA2), in order to avoid internalization and to continue to signal at the plasma membrane [10, 12, 15] . PMCA2 is one of 4 related P-type ion pumps that transport calcium out of cells [16] [17] [18] . PMCA2 is expressed in mammary epithelial cells during lactation and is important for milk calcium transport as well as mammary epithelial cell survival during milk production [19] [20] [21] [22] [23] [24] . PMCA2 is re-expressed in breast cancer cell lines, murine mammary tumors and in human breast cancers, where high PMCA2 levels predict increased mortality [12, 22, 25, 26] . PMCA2 levels correlate with HER2 levels and PMCA2 co-localizes with HER2 in human tumors [12, 22] . In breast cancer cells, PMCA2 is contained within a common multi-protein complex with HER2 and it is required for HER2 plasma membrane localization, HER2 cell surface retention and HER2 biochemical signaling. Knocking down PMCA2 expression in breast cancer cell lines results in an increase in intracellular calcium concentrations around the active HER2 signaling complex, which, in turn promotes the ubiquitination, internalization and degradation of HER2. As a result, null mutations in the Atp2b2 (PMCA2) gene impair the formation of tumors in MMTV-Neu mice [12] . In breast cancer cells, HER2 and other ErbB family members have been reported to localize to specific plasma membrane domains that are enriched in actin and lipid rafts, and that protrude from the cell surface [10-12, 27, 28]. Furthermore, localization of HER2 to these membrane protrusions is associated with the ability of HER2 to resist internalization upon activation [10] [11] [12] 27 ]. Prior studies have described a close relationship between active HER2 signaling and the presence of membrane protrusions. Disrupting these membrane structures was found to inhibit HER2 signaling while inhibition of HER2 signaling was associated with a reduction in membrane protrusions [10, 11, [29] [30] [31] . These observations prompted us to examine the effects of partial knockdown of HER2 expression on HER2 localization and membrane stability. In this report, we demonstrate that HER2 signaling is important for the formation and maintenance of membrane protrusions, at least in part, by maintaining PMCA2 expression and preventing increased intracellular calcium concentrations. Genetic or pharmacologic inhibition of HER2 signaling causes the depletion of membrane protrusions, the ubiquitination, internalization and degradation of HER2, and the loss of HER2 signaling. Materials and methods Cell culture The human breast cancer cell line, SKBR3, was obtained from ATCC and maintained in culture in DMEM +GlutaMAX-1 (Gibco-life Technologies) containing 10% fetal bovine serum (FBS) and pen/strep (Gibco-life Technologies) at 37˚C in 5% CO2. In some experiments, cells were cultured as above but in media without FBS for 16 hours followed by treatment with 100ng/ml EGF (Cell Signaling) or 50ng/ml NRG1 (Cell Signaling) for 2 hours. In experiments examining the pharmacologic inhibition of HER2, cells were treated with lapatinib at a dose of 2μM for 48 hours. Calcium and HER2 signaling PLOS ONE | https://doi.

Hands-Free User Interface for VR Headsets Based on In Situ Facial Gesture Sensing

Jinhyuk Kim, Jaekwang Cha, Shiho Kim

The typical configuration of virtual reality (VR) devices consists of a head-mounted display (HMD) and handheld controllers. As such, these units have limited utility in tasks that require hand-free operation, such as in surgical operations or assembly works in cyberspace. We propose a user interface for a VR headset based on a wearer's facial gestures for hands-free interaction, similar to a touch interface. By sensing and recognizing the expressions associated with the in situ intentional
more &raquo; ... ments of a user's facial muscles, we define a set of commands that combine predefined facial gestures with head movements. This is achieved by utilizing six pairs of infrared (IR) photocouplers positioned at the foam interface of an HMD. We demonstrate the usability and report on the user experience as well as the performance of the proposed command set using an experimental VR game without any additional controllers. We obtained more than 99% of recognition accuracy for each facial gesture throughout the three steps of experimental tests. The proposed input interface is a cost-effective and efficient solution that facilitates hands-free user operation of a VR headset using built-in infrared photocouplers positioned in the foam interface. The proposed system recognizes facial gestures and incorporates a hands-free user interface to HMD, which is similar to the touch-screen experience of a smartphone.

Most pancreatic cystic neoplasms are detected incidentally. The major challenge is identifying lesions with malignant potential or signs of malignancy. Intraductal papillary mucinous neoplasms are classified as main duct-type or branch duct-type or mixed type. Many patients with intraductal papillary mucinous neoplasm (IPMN) have no symptoms. Some patients have pancreatitis-like symptoms and elevated pancreatic enzymes. Resection is typically recommended for IPMNs with high-grade dysplasia,
more &raquo; ... s that have progressed to invasive carcinoma, and IPMNs with features concerning for malignancy or that are at high risk for developing malignancy. A 81-year-old male visited emergency room because of abdomen pain. He was diagnosed as IPMN with acute pancreatitis.

EPSR: Edge Profile Super resolution [article]

Jiun Lee, Jaekwang Kim, Inyong Yun
<span title="2021-05-12">2021</span> <i > arXiv </i> &nbsp; <span class="release-stage" >pre-print</span>
In this paper, we propose Edge Profile Super Resolution(EPSR) method to preserve structure information and to restore texture. We make EPSR by stacking modified Fractal Residual Network(mFRN) structures hierarchically and repeatedly. mFRN is made up of lots of Residual Edge Profile Blocks(REPBs) consisting of three different modules such as Residual Efficient Channel Attention Block(RECAB) module, Edge Profile(EP) module, and Context Network(CN) module. RECAB produces more informative features
more &raquo; ... ith high frequency components. From the feature, EP module produce structure informed features by generating edge profile itself. Finally, CN module captures details by exploiting high frequency information such as texture and structure with proper sharpness. As repeating the procedure in mFRN structure, our EPSR could extract high-fidelity features and thus it prevents texture loss and preserves structure with appropriate sharpness. Experimental results present that our EPSR achieves competitive performance against state-of-the-art methods in PSNR and SSIM evaluation metrics as well as visual results.

Dietary Restriction and Neuroinflammation: A Potential Mechanistic Link

Eugene Bok, Myungjin Jo, Shinrye Lee, Bo-Ram Lee, Jaekwang Kim, Hyung-Jun Kim
<span title="2019-01-22">2019</span> <i title="MDPI AG"> <a target="_blank" rel="noopener" href="https://fatcat.wiki/container/3loumxx7kzamnlu4h6x3xoz6ay" style="color: black;">International Journal of Molecular Sciences</a> </i> &nbsp;
Chronic neuroinflammation is a common feature of the aged brain, and its association with the major neurodegenerative changes involved in cognitive impairment and motor dysfunction is well established. One of the most potent antiaging interventions tested so far is dietary restriction (DR), which extends the lifespan in various organisms. Microglia and astrocytes are two major types of glial cells involved in the regulation of neuroinflammation. Accumulating evidence suggests that the
more &raquo; ... d proinflammatory activation of astrocytes and microglia is attenuated under DR. However, the molecular mechanisms underlying DR-mediated regulation of neuroinflammation are not well understood. Here, we review the current understanding of the effects of DR on neuroinflammation and suggest an underlying mechanistic link between DR and neuroinflammation that may provide novel insights into the role of DR in aging and age-associated brain disorders.
