The contribution of small and large sensory afferents to postural control in patients with peripheral neuropathy (2018)

Peripheral neuropathy (PN) is a multifarious disorder that is caused by damage to the peripheral nerves. Although the symptoms of PN vary with the etiology, most cases are characterized by impaired tactile and proprioceptive sensation that progresses in a distal to proximal manner. Balance also tends to deteriorate as the disorder becomes more severe, and those afflicted are substantially more likely to fall while walking compared with those who are healthy. Most patients with PN walk more cautiously and with greater stride variability than age-matched controls, but the majority of their falls occur when they must react to a perturbation such as a slippery or uneven surface. The purpose of this study was to first describe the role of somatosensory feedback in the control of posture and then discuss how that relationship is typically affected by the most common types of PN. A comprehensive review of the scientific literature was conducted using MEDLINE, and the relevant information was synthesized. The evidence indicates that the proprioceptive feedback that is conveyed primarily through larger type I afferents is important for postural control. However, the evidence indicates that the tactile feedback communicated through smaller type II afferents is particularly critical to the maintenance of balance. Many forms of PN often lead to chronic tactile desensitization in the soles of the feet and, although the central nervous system seems to adapt to this smaller type II afferent dysfunction by relying on more larger type I afferent reflex loops, the result is still decreased stability. We propose a model that is intended both to help explain the relationship between stability and the smaller type II afferent and the larger type I afferent feedback that may be impaired by PN and to assist in the development of pertinent rehabilitative interventions.

Application of Forecasting Power Based on Neural Network and Wilcoxon Rank Sum Test (2014)

With the development of modern power systems, the accuracy requirement for load forecasting is getting higher and higher. In this paper, the Wilcoxon rank sum test as a new mathematical method to test error, is applied to the neural network based short-term load forecasting model. The actual historical load data and the associated weather conditions factors to be considered, based on MATLAB neural network toolbox, The method to construct three different neural network model, the power load in Yichang area in 2009 was forecasted and the simulation of short-term. The simulation results show：Wilcoxon rank sum test algorithms in neural network model, not only can correctly predict，relative to the average relative error, in the statistical methods and statistical laws - especially in the face of large amounts of data - through a random sample to show a certain advantage in the overall distribution.
Toward a super imaging system [Invited] (2013)

This paper deals with the fast-developing area of computational photography where a combination of imaging techniques and efficient image processing algorithms is done to generate a super imaging system. In recent years, three main implementations of the computational photography philosophy were intensively investigated and demonstrated: (i) multiple aperture, (ii) light field photography, and (iii) multiexposure. The paper provides a mini-review of these three approaches and shows ways to improve and combine them toward a super imaging system. As a conclusion, the paper provides preliminary guidelines for fusing the three approaches into one integrated super imaging system with optimized performance.
Nanofibrillar cellulose wound dressing in skin graft donor site treatment (2016)

Based on the preliminary clinical data, NFC dressing seems to be promising for skin graft donor site treatment since it is biocompatible, attaches easily to wound bed, and remains in place until donor site has renewed. It also detaches from the epithelialized skin by itself.
Objectives and Challenges of the Utilization of User-Interaction Data in Software Development (2018)

Understanding users, their requirements and usage patterns helps building better software. To continuously improve operations, user-interaction (U-I) data can provide developers with interesting new possibilities. This study aims at gaining an understanding of how software teams can start the use of U-I data and what challenges they face with it. In this paper, we describe three cases from different organizations. This includes explaining the activities, objectives, and challenges of each team in their efforts to begin using U-I data. We conducted the study with Action Design Research (ADR) method, resulting in findings from each case by intervening in the work of these teams. As a contribution, we designed a U-I data utilization method that summarizes teams' activities. Secondly, we refined and validated the categorizations of U-I data analysis and utilization objectives, and finally we categorized the challenges that the case teams faced. Together, these contributions lay out clear steps also for other software teams in starting the utilization of U-I data.
Considerations for MEMS packaging (2004)

MEMS devices have complex topography and delicate moving parts. Unlike microelectronics which really never wants to "touch" the media, MEMS is designed to interact with media for sensing and actuation in a special environment. The variety and specialty of MEMS challenge its packaging. Generally, MEMS can be packed either at wafer level or die level. There are a lot of researches and progresses on the wafer level packaging recently. In this paper, the requirements of MEMS packaging are outlined from the unique features of MEMS devices. Various MEMS packaging methods and materials are introduced as well. More discussions are given to reduce stress and improve hermeticity of MEMS packages at both die level and wafer level.
Covalent Attachment of a Transition Metal Coordination Complex to Functionalized Oligo(phenylene-ethynylene) Self-Assembled Monolayers (2005)

We have investigated the reaction of tetrakis(dimethylamido)titanium, Ti[N(CH(3))(2)](4), with N-isopropyl-N-[4-(thien-3-ylethynyl) phenyl] amine and N-isopropyl-N-(4-{[4-(thien-3-ylethynyl) phenyl]ethynyl}phenyl) amine self-assembled monolayers (SAMs), on polycrystalline Au substrates. The structure of the SAMs themselves has also been investigated. Both molecules form SAMs on polycrystalline Au bound by the thiophene group. The longer-molecular-backbone molecule forms a denser SAM, with molecules characterized by a smaller tilt angle. X-ray photoelectron spectroscopy (XPS) and angle-resolved XPS have been employed to examine the kinetics of adsorption, the spatial extent of reaction, and the stoichiometry of reaction. For both the SAMs, adsorption is described well by first-order Langmuirian kinetics, and adsorption is self-limiting from T(s) = -50 to 30 degrees C. The use of angle-resolved XPS clearly demonstrates that the Ti[N(CH(3))(2)](4) reacts exclusively with the isopropylamine end group via ligand exchange, and there is no penetration of the SAM, followed by reaction at the SAM-Au interface. Moreover, the SAM molecules remain bound to the Au surface via their thiopene functionalites. From XPS, we have found that, in both cases, approximately one Ti[N(CH(3))(2)](4) is adsorbed per two SAM molecules.
자원봉사자들의 탈북자 지원 경험 분석 -설문 결과를 중심으로 (2001)

Objectives: Since 1994, the number of North Korean defectors, escaping North Korea and entering South Korea, has increased rapidly. The Government has provided most of the support for the defectors` adaptation to their new society. But as the number of defectors has increased, and the support needs have become more various, the support of volunteers from non-governmental organization (NGO) has become very important. To raise the level of the success and effectiveness of the support from the volunteers, their experiences were surveyed and analyzed. Methods: This study surveyed 83 volunteers of 7 NGOs involved in helping North Korean defectors` adaptation to South Korean society-48 men and 34 women. Results: In their relationships with defectors, women volunteers have more difficulties in their first 3 months. However volunteers in their 50s and 60s tend to have more stable and better relationships with defectors than younger volunteers. Many volunteers statedexperiences of human difficulties with defectors, for example, mistrust and anxiety in human relationship (n=34, 41.0%), psychological maladjustment (n=19, 22.9%), different ways of thinking and culture (n=17, 20.5%), economic difficulties (n=10, 12.0%), and lack of independence spirit (n=6, 7.2%). The volunteers said they have feelings of goodwill toward defectors when defectors showed warm heart (n=30, 36.1%), politeness (n=30, 36.1%), positive and active character (n=24, 28.9%), strong will (n=17, 20.5%), and plainness (n=14, 16.0%). The volunteers stated an absence of goodwill feelings to defectors when defectors showed uncompromising and aggressive attitudes (n=29, 34.9%), lack of independent will (n=28, 33.7%), selfishness (n=18, 21.7%), and avoidance of making human relationship (n=16, 19.3%). As for adequate training before commencing activity, 5 volunteers (6.0%) said they had received enough education before their activity, 31(37.3%) relatively enough, 38 (45.8%) relatively not enough, and 9 (10.8%) absolutely not enough education. If they were the owners of a company, 27 volunteers (51 .9%) said they would want to hire defectors even if the defectors did not have the required ability. Conclusion: These results showed that NGO`s volunteers have a friendlier attitude to defectors than policemen in charge and public officials, which is their strong point. Women volunteers experience more difficulties in their early relationships with defectors, suggesting the need for a specific pre-education program for women volunteers. Furthermore, NGOs would benefit from an increase in the number of volunteers in their 50`s and 60`s. Both volunteers and defectors need to understand each other to a deeper extent and the characteristics to which South Korean volunteers feel goodwill need to be used in their education.
Ultrastructural Study of Capillary Permeability of Liposome-encapsulated Cisplatin in an Experimental Rat Brain Tumor Model (1989)

The anticancer chemotherapeutic agent cisplatin (cis-diamminedichloroplatinum) has several disadvantages, including extreme nephrotoxicity, rapid binding to plasma proteins, and poor penetration into the central nervous system. Liposomes would seem to be suitable as carriers of cisplatin to brain tumors. This ultrastructural study was undertaken to identify the capillary permeability of liposome-encapsulated cisplatin in a rat brain tumor model. Brain tumors were induced transplacentally with a single intravenous dose of 50 mg/kg of ethylnitrosourea (ENU). One ml of liposome-encapsulated cisplatin and ferritin prepared from phosphatidylcholine and cholesterol (molar ratio 7:2) was administered via the carotid artery to rats with ENU-induced brain tumors. The tumor platinum content and that of the contralateral hemisphere were assayed by flameless atomic absorption spectrometry. The presence of ferritin-bearing liposomes was demonstrated by electron microscopy of brain capillary endothelium as well as tumor cells. Thirty minutes after drug administration, the average dry-weight platinum concentrations were 3.98 +/- 0.50 micrograms/g within the intracerebral tumors and 0.72 +/- 0.24 micrograms/g in the contralateral hemispheres. Electron microscopic ultrastructural study, which can distinguish ferritin-bearing liposomes from cell materials, demonstrated the presence of liposomes containing ferritin in both cell surface folds and capillary endothelial cells and also within tumor cells. An enlarged electron micrograph of a liposome with a diameter of approximately 0.2 micron suggested the presence of ferritin molecules in the lamellar structure. Liposome-encapsulated cisplatin is apparently able to pass the blood-brain barrier and should be useful in the chemotherapy of glioma.
Electrical Performance and Scalability of Pt Dispersed SiO<sub>2</sub>Nanometallic Resistance Switch (2013)

Highly reproducible bipolar resistance switching was recently demonstrated in a composite material of Pt nanoparticles dispersed in silicon dioxide. Here, we examine the electrical performance and scalability of this system and demonstrate devices with ultrafast (<100 ps) switching, long state retention (no measurable relaxation after 6 months), and high endurance (>3 × 10(7) cycles). A possible switching mechanism based on ion motion in the film is discussed based on these observations.
Strategic Structural Design of a Gel Polymer Electrolyte toward a High Efficiency Lithium-Ion Battery (2019)

Electrolytes have played critical roles in electrochemical energy storage. In Li-ion battery, liquid electrolytes have shown their excellent performances over decades, such as high ionic conductivity (∼10–3 S cm–1) and good contacts with electrodes. However, the use of liquid electrolytes often brought risks associated with leakage and combustion of organic electrolytes. Hence, polymer electrolytes become potential candidates to replace liquid electrolyte systems. Although solid polymer electrolytes (SPEs) offer better safety and good mechanical properties to take over liquid electrolytes, most of them only deliver low ionic conductivities (∼10–8 S cm–1) and poor contact with electrodes, resulting in poor cycle performance and low electrical capacity of the batteries. In addition, gel polymer electrolytes (GPEs) have received increasing research attention due to their relevant characteristics, which extend from liquid electrolytes and solid polymer electrolytes. In this review, state-of-the-art samples of gel polymer electrolytes are elucidated with respect to their structural design and electrochemical properties to determine their application potential in Li-ion batteries (LIBs). First, we present the general requirements of GPEs for LIBs applications, followed by important electrochemical properties of GPEs for LIBs including ionic conductivity, transference number, and ionic transport mechanisms. Furthermore, recent progress of common polymers, namely, polyether, polyvinyl, polynitrile, polycarbonate, and polyacrylate, as polymer host of GPEs has been carefully explained. Finally, the alternative polymers were also discussed to provide new approaches for further developments of GPEs to fulfill the demanded properties for practical applications.
Observation of the spin Seebeck effect in epitaxial Fe3O4 thin films (2013)

We report the experimental observation of the spin Seebeck effect in magnetite thin films. The signal observed at temperatures above the Verwey transition is a contribution from both the anomalous Nernst (ANE) and spin Seebeck (SSE) effects. The contribution from the ANE of the Fe3O4 layer to the SSE is found to be negligible due to the resistivity difference between Fe3O4 and Pt layers. Below the Verwey transition, the SSE is free from the ANE of the ferromagnetic layer and it is also found to dominate over the ANE due to magnetic proximity effect on the Pt layer.

Norepinephrine Induces Vascular Endothelial Growth Factor Gene Expression in Brown Adipocytes through a β-Adrenoreceptor/cAMP/Protein Kinase A Pathway Involving Src but Independently of Erk1/2 (2000)

To identify the signaling pathway that mediates the adrenergic stimulation of the expression of the gene for vascular endothelial growth factor (VEGF) during physiologically induced angiogenesis, we examined mouse brown adipocytes in primary culture. The endogenous adrenergic neurotransmitter norepinephrine (NE) induced VEGF expression 3-fold, in a dose- and time-dependent manner (EC(50) approximately 90 nm). Also, the hypoxia-mimicking agent cobalt, as well as serum and phorbol ester, induced VEGF expression, but the effect of NE was additive to each of these factors, implying that a separate signaling mechanism for the NE-mediated induction was activated. The NE effect was abolished by propranolol and mimicked by isoprenaline or BRL-37344 and was thus mediated via beta-adrenoreceptors. The NE-induced VEGF expression was fully cAMP mediated, an effect which was inhibited by H-89 and thus was dependent on protein kinase A activity. Involvement of other adrenergic signaling pathways (alpha(1)-adrenoreceptors, Ca(2+), protein kinase C, alpha(2)-adrenoreceptors, and pertussis toxin-sensitive G(i)-proteins) was excluded. The specific inhibitor of Src tyrosine kinases, PP2, markedly reduced the stimulation by NE, which demonstrates that a cAMP-dependent Src-mediated pathway is positively connected to VEGF expression. However, inhibition of Erk1/2 MAP kinases by PD98059 was without effect. NE did not prolong VEGF mRNA half-life and its effect was thus transcriptional, and was independent of protein synthesis. These results demonstrate that adrenergic stimulation, through beta-adrenoreceptor/cAMP/protein kinase A signaling, recruits a pathway that branches off from the NE-activated Src-Erk1/2 cascade to enhance transcription of the VEGF gene.
Sensor data analysis and anomaly detection using predictive analytics for process industries (2015)

Pervasive sensing is one of the most prominent technologies being adapted by current process industry. Every process industry is highly equipped with wireless sensors for process monitoring in which location, human intervention is to be limited. Thus, major challenge with these numerous sensors is to store and analyze large volume of sensor data stream. This paper focuses on sensor data analysis along with anomaly detection specific to process sector because the placement and nature of the data generated from these sensors follows a specific pattern during process flow. This data is more structured than other type of big data, in which data is more unstructured. No assurance that any single algorithm can produce optimized results. So this paper presents a generic frame work with ensemble of methods such as probability and statistics, Neural Networks and Clustering. Here Neural Net is supervised learning model to predict new data based on trained data. But unseen data is wrongly predictable by Neural nets. For that reason clustering is used as Unsupervised learning model to efficiently handle concept drifts in sensor data stream. These solutions are implemented to various data scenarios with practical means to improve prediction and anomaly detection accuracy of equipment as well as process flows. To the best of our knowledge no single framework is available to fully analyse sensor data stream related to independent, correlation based, group wise with respect to process flow segmentation and process and sub process hierarchy analysis.

Potential and Thermodynamics of Graphite Anodes in Li-Ion Cells (2000)

Lithium graphite intercalation compound (Li‐GIC) has potential plateaus depending on its staging in Li/Li‐GIC cells. It is believed that the entropy of each stage is different depending on the total number of states created by the inserted and electrons in Li‐GIC. On this basis, the entropy change with Li insertion has been calculated and the potential, using the reaction Gibbs function, has been estimated. The entropy term in the usual potential equation diverges for Li vacant and Li full GICs. The equation was improved and had finite values for these GICs depending on the mean size of the crystallites in the GIC. By the introduction of the intercalation pressure to our model, we confirmed that Li‐GIC is unstable and decomposes into Li‐poor and Li‐rich phases. The potential was calculated using the entropy term for Li full GIC. The result agreed well with the experimental value. The entropy term contribution was very large for the potential difference of each plateau. © 2000 The Electrochemical Society. All rights reserved.
In vitro transcription of pathogenesis-related genes by purified RNA polymerase from Staphylococcus aureus (1995)

The RNA polymerase (RNAP) holoenzyme of Staphylococcus aureus was purified by DNA affinity, gel filtration, and ion-exchange chromatography. This RNAP contained four major subunits with apparent molecular masses of 165, 130, 60, and 47 kDa. All four subunits of the RNAP were serologically related to the subunits of Escherichia coli E sigma 70 holoenzyme by Western immunoblot analysis. The 60-kDa subunit was subsequently isolated and found to react with a monoclonal antibody specific to the E. coli sigma 70 subunit. This sigma 70-related protein allowed E. coli core RNAP promoter-specific initiation and increased transcription by S. aureus RNAP that is unsaturated with sigma. We therefore suggest that this 60-kDa protein is a sigma factor. Purified S. aureus RNAP transcribed from the promoters of several important S. aureus virulence genes (sea, sec, hla, and agr P2) in vitro. The in vitro transcription start sites of the sea, sec, and agr P2 promoters, mapped by primer extension, were similar to those identified in vivo. The putative promoter hexamers of these three genes showed strong sequence similarity to the E. coli sigma 70 consensus promoter, and transcription by E sigma 70 from some of these promoters has been observed. Conversely, S. aureus RNAP does not transcribe from all E. coli sigma 70-dependent promoters. Taken together, our results indicate that the promoter sequences recognized by purified S. aureus RNAP are similar but not identical to those recognized by E. coli E sigma 70.
