Mobile Energy Transfer in Internet of Things (2019)

Internet of Things (IoT) is powering up smart cities by connecting all kinds of electronic devices. The power supply problem of IoT devices constitutes a major challenge in current IoT development, due to the poor battery endurance as well as the troublesome cable deployment. The wireless power transfer (WPT) technology has recently emerged as a promising solution. Yet, existing WPT advances cannot support free and mobile charging like Wi-Fi communications. To this end, the concept of mobile energy transfer (MET) is proposed, which relies critically on a resonant beam charging (RBC) technology. The adaptive (A) RBC technology builds on RBC, but aims at improving the charging efficiency by charging devices at device preferred current and voltage levels adaptively. A mobile ARBC scheme is developed relying on an adaptive source power control. Extensive numerical simulations using a 1000-mAh Li-ion battery show that the mobile ARBC outperforms simple charging schemes, such as the constant power charging, the profile-adaptive charging, and the distance-adaptive charging in saving energy.
One-Year Observation of Wistar Rats after Intravenous Infusion of Hemoglobin-Vesicles (Artificial Oxygen Carriers) (2007)

Hemoglobin-vesicles (HbV) or liposome-encapsulated Hb are artificial oxygen carriers. Our previous studies of the bolus infusion of HbV into Wistar rats showed that HbV was captured by the reticuloendothelial system from the blood stream and degraded completely with no deteriorative effect for 2 weeks. However, one authority on artificial organs research suggested conducting a one-year observation because he experienced, with one lipid-emulsified perfluorocarbon (PFC), that rats died within one year from a pulmonary abnormality after receiving the PFC emulsion due to the unstable dispersion state (personal communication). We thought this would never happen for HbV because the dispersion state of HbV is stable with PEG-modification. To confirm this, we made one-year observations after HbV infusion as suggested. Five male Wistar rats intravenously received 20 ml/kg HbV suspended in saline ([Hb] = 10 g/dL). They were housed in separated cages and provided with food and water ad libitum. All rats survived one year, and were apparently healthy. Their body weights (821+/-75 g) reflected obesity from their confinement in small cages. No histopathological abnormality was found in the lung. Plasma biochemical analyses showed overall normal organ functions. In our previous report, plasma lipid levels increased transiently at 1 or 2 days; then they reverted to the control level at 7 days. One year later, the rats showed much higher plasma lipid levels, a symptom of hyperlipidemia that is attributable to obesity and aging. It seemed the transient increases at the early days had no impact compared with the levels of hyperlipemia of the old rats.

Nest Success, Abundance, and Length Distribution of Age-0 Largemouth Bass in Sanctuaries and Areas Open to Fishing (2016)

Protecting an area from fishing by establishing a sanctuary is one possible management strategy that could protect adults during spawning, potentially enhancing recruitment in freshwater systems. From 2001-2006, Briery Creek Lake (342 ha), Virginia was characterized by high fishing pressure in spring when adults were spawning and low abundance of age-0 Largemouth Bass Micropterus salmoides . Therefore, we created two sanctuaries in 2006 in Briery Creek Lake that were closed to angling and boats; these areas provided protection for nest-guarding male Largemouth Bass. However, the nest-success rate did not differ significantly between open areas and sanctuaries (30-40% nest success). Catch per unit effort of age-0 Largemouth Bass did not differ between areas open to angling (28.8/h and 39.0/h in 2006 and 2007, respectively) and sanctuaries (14.6/h and 22.2/h in 2006 and 2007, respectively). Similarly, mean length-at-capture was not different for age-0 Largemouth Bass between sanctuaries and open areas. Closing spawning areas to fishing may not be an effective management option to increase Largemouth Bass recruitment success in Briery Creek Lake.

Interferon-Inducible Protein 9 (CXCL11)-Induced Cell Motility in Keratinocytes Requires Calcium Flux-Dependent Activation of μ-Calpain (2005)

Keratinocyte migration is critical to reepithelialization during wound repair. The motility response is promoted by growth factors, cytokines, and cytokines produced in the wound bed, including those that activate the epidermal growth factor (EGF) receptor. The Alu-Leu-Arg-negative CXC chemokine interferon-inducible protein 9 (IP-9; also known as CXCL11, I-TAC, beta-R1, and H-174) is produced by keratinocytes in response to injury. As keratinocytes also express the receptor, CXCR3, this prompted us to examine the role and molecular mechanism by which IP-9 regulates keratinocyte motility. Unexpectedly, as CXCR3 liganding blocks growth factor-induced motility in fibroblasts, IP-9 alone promoted motility in undifferentiated keratinocytes (37 +/- 6% of the level of the highly motogenic EGF) as determined in a two-dimensional in vitro wound healing assay. IP-9 even enhanced EGF-induced motility in undifferentiated keratinocytes (116 +/- 5%; P < 0.05 compared to EGF alone), suggesting two separate mechanisms of action. IP-9-increased motility and -decreased adhesiveness required the intracellular protease calpain. The increases in both motility and calpain activity by IP-9 were blocked by pharmacological and molecular inhibition of phospholipase C-beta3 and chelation of calcium, which prevented an intracellular calcium flux. Molecular downregulation or RNA interference-mediated depletion of mu-calpain (calpain 1) but not M-calpain (calpain 2) blocked IP-9-induced calpain activation and motility. In accord with elimination of IP-9-induced de-adhesion, RNA interference-mediated depletion of calpain 1 but not calpain 2 prevented cleavage of the focal adhesion component focal adhesion kinase and disassembly of vinculin aggregates. In comparison, EGF-induced motility of the same undifferentiated keratinocytes requires the previously described extracellular signal-regulated kinase to the M-calpain pathway. These data demonstrate that while both EGF- and IP-9-induced motility in keratinocytes requires calpain activity, the isoform of calpain triggered depends on the nature of the receptor for the particular ligand. Interestingly, physiological nonapoptotic calcium fluxes were capable of activating mu-calpain, implying that the calcium requirement of mu-calpain for activation is attained during cell signaling. This is also the first demonstration of differential activation of the two ubiquitous calpain isoforms in the same cell by different signals.
The use of porous prostheses in delayed reconstruction of total hip replacements that have failed because of infection. (1994)

Between March 1984 and March 1989, thirty-four patients who had an infection at the site of a cemented total hip prosthesis were managed with resection arthroplasty and delayed implantation of a porous total hip prosthesis without cement. The interval from the time of the resection arthroplasty to the implantation of another prosthesis averaged eight months (range, three to nineteen months). At an average of forty-seven months (range, twenty-four to seventy-two months) after the reimplantation, six patients (18 per cent) had recurrence of the infection. Patients who had rheumatoid arthritis were at significantly higher risk for the development of a recurrent infection (p < 0.01). Of the twenty-eight patients who did not have a recurrent infection, six had definite radiographic evidence of loosening of the femoral component at the latest follow-up evaluation. For twenty-five of the twenty-eight patients, sufficient data were available for calculation of the Mayo Clinic hip score; only fourteen (56 per cent) of these patients had a satisfactory functional outcome. The high (68 per cent) rate of complications and the long-term durability of the prosthesis in these patients remain a concern. The fact that 18 per cent of the patients had a recurrent infection suggests that avoidance of the use of bone cement does not improve the rate of resolution of infection after a delayed revision operation in patients who have an infection following a total hip arthroplasty.

Unravelling metallic contaminants in complex polyimide heterostructures using deep ultraviolet spectroscopic ellipsometry (2023)

Metallic contaminants in complex heterostructures are important topics due to their significant roles in determining physical properties as well as device performance. Heterostructures of polyimide via on Al pad and Cu redistribution layer (RDL) on polyimide have shown exotic properties and are important for advanced semiconductor packaging systems. One main problem is significant leakage current variations, which affect the performance of the devices, yet the origin is far from understood. Furthermore, metal contaminations would occur at the buried interfaces and it is particularly challenging to probe them. Until now, the electronic and optical properties of complex polyimide heterostructures and the roles of metallic contaminants, especially in the deep ultraviolet (DUV) have not been studied extensively. Herewith, using spectroscopic ellipsometry (SE) in a broad DUV range supported with finite-difference time-domain (FDTD) calculations, we determine optical properties of contaminants with various concentrations and reveal their influence on device performance of under-bump vias and redistribution layer (RDL) architectures. The complex dielectric function shows varying contamination levels and different metals responsible for chip performance. Metallic contaminants are found embedded within 50 nm in the polyimide and different metals are distinguishable with varying concentrations, in agreement with contact measurements in highly complex structures. Our result shows the potency of spectroscopic ellipsometry in the DUV and paves the way for non-destructive, advanced quality control and metrology applications in integrated advanced electronics packaging systems.

Supervisory control method for redundant technical systems (2017)

The redundant equipment system configuration control problem is considered. The proposed method is based on the use of software and hardware, called supervisors, the number of which corresponds to the number of possible configurations. Each supervisor monitors its system configuration with the determination of its readiness index. Then, the preferred configuration is selected and implemented by performance indicators based on arbitration between supervisors with positive readiness indices. An example of redundancy control in a simplified aircraft navigation system is presented.
PAX6 Isoforms, along with Reprogramming Factors, Differentially Regulate the Induction of Cornea-specific Genes (2016)

PAX6 is the key transcription factor involved in eye development in humans, but the differential functions of the two PAX6 isoforms, isoform-a and isoform-b, are largely unknown. To reveal their function in the corneal epithelium, PAX6 isoforms, along with reprogramming factors, were transduced into human non-ocular epithelial cells. Herein, we show that the two PAX6 isoforms differentially and cooperatively regulate the expression of genes specific to the structure and functions of the corneal epithelium, particularly keratin 3 (KRT3) and keratin 12 (KRT12). PAX6 isoform-a induced KRT3 expression by targeting its upstream region. KLF4 enhanced this induction. A combination of PAX6 isoform-b, KLF4, and OCT4 induced KRT12 expression. These new findings will contribute to furthering the understanding of the molecular basis of the corneal epithelium specific phenotype.

Optimization for Superplasticity in Ultrafine-Grained Al-Mg-Sc Alloys Using Equal-Channel Angular Pressing (2001)

Ultrafine grain sizes may be achieved in materials subjected to severe plastic deformation through processing procedures such as equal-channel angular pressing (ECAP). Experiments were conducted to evaluate the factors influencing the superplastic characteristics of Al-Mg-Sc alloys. Specifically, detailed testing was undertaken to determine the influence of (i) the processing route, (ii) the strain introduced by ECAP and (iii) the Mg content.

The Effect of Graft-versus-Host Disease on T Cell Production and Homeostasis (1999)

The aim of this work was to decipher how graft-versus-host disease (GVHD) affects T cell production and homeostasis. In GVHD+ mice, thymic output was decreased fourfold relative to normal mice, but was sufficient to maintain a T cell repertoire with normal diversity in terms of Vbeta usage. Lymphoid hypoplasia in GVHD+ mice was caused mainly by a lessened expansion of the peripheral postthymic T cell compartment. In 5-bromo-2'-deoxyuridine pulse-chase experiments, resident T cells in the spleen of GVHD+ mice showed a normal turnover rate (proliferation and half-life). When transferred into thymectomized GVHD- secondary hosts, T cells from GVHD+ mice expanded normally. In contrast, normal T cells failed to expand when injected into GVHD+ mice. Thus, the reduced size of the postthymic compartment in GVHD+ mice was not due to an intrinsic lymphocyte defect, but to an extrinsic microenvironment abnormality. We suggest that this extrinsic anomaly is consistent with a reduced number of functional peripheral T cell niches. Therefore, our results show that GVHD-associated T cell hypoplasia is largely caused by a perturbed homeostasis of the peripheral compartment. Furthermore, they suggest that damage to the microenvironment of secondary lymphoid organs may represent an heretofore unrecognized cause of acquired T cell hypoplasia.

Beam steering with solid-state devices represents the cutting-edge technology for next-generation LiDARs and free-space communication transceivers. Here we demonstrate a platform based on a metalens on a 2D array of switchable silicon microring emitters. This platform enables scalable, efficient, and compact devices that steer in two dimensions using a single wavelength. We show a field of view of 12.4° × 26.8° using an electrical power of less than 83 mW, offering a solution for practical miniature beam steerers.
High Density Geopolymers: A Step Forward Towards Low Carbon Footprint Cementing Operations (2023)

Abstract The utilization of ordinary Portland cement (OPC) in well cementing is accompanied by technical and environmental problems, leading researchers to explore alternative materials that address these issues and promote eco-friendliness. Geopolymer technology, widely used in construction and other industries, has not yet been fully implemented in oil and gas well cementing. Industrial waste materials, such as Class F fly ash (FFA), can be utilized to improve cement properties or create new cement binders. Hematite is used as a weighting agent to increase cement slurry density. However, heavy particle sedimentation in cement and geopolymer slurries is a significant issue that leads to heterogenous properties along the cemented section. This study introduces a new class of geopolymers that use both hematite and Micromax as weighting materials for high-density well cementing applications. One system only used hematite, while the other used both hematite and Micromax in an effort to eliminate sedimentation issues associated with hematite in geopolymers. The effects of adding Micromax on different FFA geopolymer properties were also evaluated. The study evaluated mixability, rheology, and pumpability to determine the mix design, which was then used to examine other properties such as strength, and density variation. The results showed that adding Micromax to hematite reduced the average density variation from 12.5% to 3.9%. Micromax addition also decreased plastic viscosity by 44.5% and fluid loss by 10.5%. Both systems performed closely in terms of strength.
Evidence for an intracellular niche forBordetella pertussisin broncho-alveolar lavage cells of mice (1999)

Bordetella pertussis can attach, invade and survive intracellularly in human macrophages in vitro. To study the significance of this bacterial feature in vivo, we analyzed the presence of viable bacteria in broncho-alveolar lavage (BAL) cells of mice infected with B. pertussis. We found B. pertussis to be present in a viable state in BAL fluid cells until at least 19 days after infection, suggesting B. pertussis to be able to survive in those cells. This intracellular niche may play an important role in the pathogenesis of pertussis. Pertussis toxin and the RGD sequence of the virulence factor filamentous hemagglutinin (FHA) both play a role in the attachment of B. pertussis to human and mouse macrophages in vitro and we hypothesized these virulence factors to be required for invasion and subsequent intracellular survival of B. pertussis in macrophages in vivo. A B. pertussis double mutant, in which the FHA RGD motif was changed to RAD and the ptx genes were deleted, was also found in a viable state in BAL fluid cells, albeit at lower levels than the wild-type strain. In our model, uptake of B. pertussis by alveolar phagocytes in vivo is thus, at least in part, determined by the bacterial virulence factors FHA and pertussis toxin.
Simple Fabrication of Carbon Nanotubes from Ethanol using an Ultrasonic Spray Pyrolysis (2013)

Carbon nanotubes of diameter (20"“100 nm) are synthesized by pyrolyzing a sprayed solution of Fe(C5H5)2 and C2H5OH in an Ar atmosphere at relatively low temperatures (around 800 oC). The tubular structures consist of highly crystalline nested graphene cylinders (&lt;200 concentric tubes). Tube diameter can be controlled by varying the furnace temperature, carrier gas flow rate and the Fe:C ratio within the precursor solution. This low cost route for the synthesis of carbon nanotubes is advantageous due the low pyrolytic temperature, safety, processable in atmospheric pressure, and scalable.
The protective role of macrophages in Francisella tularensis infection (MPF3P.819) (2014)

Abstract Francisella tularensis causes lethal pneumonia following infection of the lungs. F. tularensis is considered to be an intracellular pathogen that targets macrophages for replication. We therefore hypothesized that depletion of alveolar macrophages would impede bacterial replication and improve host survival. However, it was found that macrophages are essential for survival of F. tularensis infection and depletion of these cells reduced survival rates following infection. Mice with a macrophage-specific defect in interferon gamma (IFN-γ) signaling (MIIG mice) were also highly sensitive to infection, exhibiting reduced survival rates, reduced mean time to death, and increased bacterial burdens in lungs, liver, and spleen relative to wild-type mice. We have previously found that treatment with exogenous interleukin 12 (IL-12) protects against F. tularensis infection; this protection was lost in MIIG mice. MIIG mice also exhibited reduced neutrophil recruitment to the lungs following infection. Systemic neutrophil depletion was found to render mice highly sensitive to pneumonic F. tularensis infection. Furthermore, IL-12-mediated protection required NADPH activity. These results indicate that lung macrophages serve a critical protective role in pneumonic F. tularensis infection. Macrophages require IFN-γ signaling to mediate protection, which ultimately results in recruitment of neutrophils to further aid in survival from infection.
