Wireless Sensor-based Agricultural Monitoring System (2014)

Today energy resources are becoming scarcer and therefore more valuable. In conjunction with the population growth over last century, the need for finding new, more efficient, and sustainable methods of agricultural cultivation and food production has become more critical. To facilitate this process, we are designing, building, and evaluating a system for precision agriculture which provides farmers with useful data about the soil, the water supply, and the general condition of their fields in a user friendly, easily accessible manner. Our system aims to make cultivation and irrigation more efficient as the farmer is able to make better informed decisions and thus save time and resources. The diversity of location and climatic effects upon agricultural cultivation, along with other environmental parameters over time makes the farmer’s decision-making process more complicated and requires additional empirical knowledge. Applying wireless sensor networks for monitoring environmental parameters and combining this information with a user-customized web service may enable farmers to exploit their knowledge in an efficient way in order to extract the best results from their agricultural cultivation. The system can scale based on each farmer’s demands and the resulting ensemble of collected information may represent a valuable resource for future use, in addition to its use for real-time decision making. The design of the precision agriculture system contains a prototype solution regarding the sensor platform and a customizable service that can be utilized in different ways and by several entities.
Therapeutic Efficacy of Cryopreserved, Allogeneic Extracellular Vesicles for Treatment of Acute Myocardial Infarction (2021)

Extracellular vesicles (EV) that are derived from endothelial progenitor cells (EPC) have been determined to be a novel therapy for acute myocardial infarction, with a promise for immediate "off-the-shelf" delivery. Early experience suggests delivery of EVs from allogeneic sources is safe. Yet, clinical translation of this therapy requires assurances of both EV stability following cryopreservation and absence of an adverse immunologic response to EVs from allogeneic donors. Thus, more bioactivity studies on allogeneic EVs after cold storage are necessary to establish quality standards for its widespread clinical use. Thus, in this study, we aimed to demonstrate the safety and efficacy in delivering cryopreserved EVs in allogeneic recipients as a therapy for acute myocardial infarction.In this present study, we have analyzed the cardioprotective effects of allogeneic EPC-derived EVs after storage at -80°C for 2 months, using a shear-thinning gel (STG) as an in vivo delivery vehicle. EV size, proteome, and nucleic acid cargo were observed to remain steady through extended cryopreservation via nanoparticle tracking analysis, mass spectrometry, and nanodrop analysis, respectively. Fresh and previously frozen EVs in STG were delivered intramyocardially in a rat model of myocardial infarction (MI), with both showing improvements in contractility, angiogenesis, and scar thickness in comparison to phosphate-buffered saline (PBS) and STG controls at 4 weeks post-MI. Pathologic analyses and flow cytometry revealed minimal inflammatory and immune upregulation upon exposure of tissue to EVs pooled from allogeneic donor cells.Allogeneic EPC-EVs have been known to elicit minimal immune activity and retain therapeutic efficacy after at least 2 months of cryopreservation in a post-MI model.
Interleukin 1-receptor antagonist blocks interleukin 1-induced sleep and fever (1991)

The recent purification and characterization of an interleukin 1-receptor antagonist (IL-1ra) has provided an additional means of elucidating the mechanisms involved in the responses initiated by IL-1. Central administration of IL-1 to rabbits results in a characteristic febrile response and in increased non-rapid-eye-movement sleep (NREMS). In this study, rabbits received various doses of IL-1ra (10-1,000 micrograms) or pyrogen-free saline intracerebroventricularly, and sleep-wake activity and brain temperature (Tbr) were determined for the next 24 h. All doses of IL-1ra tested tended to reduce NREMS in the first postinjection hour with little effect on Tbr. When rabbits were pretreated with 100 micrograms IL-1ra and then injected with 10 ng IL-1, the characteristic IL-1-induced febrile and NREMS-promoting effects were completely blocked.
Confined compressive strength analysis can improve PDC bit selection. [Polycrystalline Diamond Compact] (1994)

A rock strength analysis program, through intensive log analysis, can quantify rock hardness in terms of confined compressive strength to identify intervals suited for drilling with polycrystalline diamond compact (PDC) bits. Additionally, knowing the confined compressive strength helps determine the optimum PDC bit for the intervals. Computing rock strength as confined compressive strength can more accurately characterize a rock's actual hardness downhole than other methods. the information can be used to improve bit selections and to help adjust drilling parameters to reduce drilling costs. Empirical data compiled from numerous field strength analyses have provided a guide to selecting PDC drill bits. A computer analysis program has been developed to aid in PDC bit selection. The program more accurately defines rock hardness in terms of confined strength, which approximates the in situ rock hardness downhole. Unconfined compressive strength is rock hardness at atmospheric pressure. The program uses sonic and gamma ray logs as well as numerous input data from mud logs. Within the range of lithologies for which the program is valid, rock hardness can be determine with improved accuracy. The program's output is typically graphed in a log format displaying raw data traces from well logs, computer-interpreted lithology, the calculatedmore » values of confined compressive strength, and various optional rock mechanic outputs.« less

Peroxide‐based oxygen generating topical wound dressing for enhancing healing of dermal wounds (2015)

Oxygen generating biomaterials represent a new trend in regenerative medicine that aims to generate and supply oxygen at the site of requirement, to support tissue healing and regeneration. To enhance the healing of dermal wounds, we have developed a highly portable, in situ oxygen generating wound dressings that uses sodium percarbonate (SPO) and calcium peroxide (CPO) as chemical oxygen sources. The dressing continuously generated oxygen for more than 3 days, after which it was replaced. In the in vivo testing on porcine full-thickness porcine wound model, the SPO/CPO dressing showed enhanced wound healing during the 8 week study period. Quantitative measurements of wound healing related parameters, such as wound closure, reepithelialization, epidermal thickness and collagen content of dermis showed that supplying oxygen topically using the SPO/CPO dressing significantly accelerated the wound healing. An increase in neovascularization, as determined using Von Willebrand factor (vWF) and CD31 staining, was also observed in the presence of SPO/CPO dressing. This novel design for a wound dressing that contains oxygen generating biomaterials (SPO/CPO) for supplying topical oxygen, may find utility in treating various types of acute to chronic wounds.
Inositol biosynthesis is fine‐tuned by inositol pyrophosphates in Saccharomyces cerevisiae (2013)

In yeast , inositol biosynthesis is coordinated with the synthesis of phospholipids by controlling the expression of enzymes in the biosynthetic pathways. Inositol pyrophosphates, most recently characterized in the inositide family, have diverse roles in phosphate signaling and other important cellular processes. However, little is known about the function of inositol pyrophosphates in the biosynthesis of inositol and phospholipids. The objective of this study is to understand the mechanistic links between inositol metabolism and inositol pyrophosphates. Our results indicated that inositol pyrophosphate deficient mutants kcs1Δ and vip1Δ exhibit decreased inositol biosynthesis due to decreased derepression of INO1, which encodes the rate‐limiting enzyme for inositol biosynthesis. Further studies revealed that the inositol pyrophosphate kinase activity and the basic leucine zipper (bZIP) domains in KCS1 are both required for optimal INO1 expression. Interestingly, the levels of Kcs1p correlate with INO1 expression. We conclude that conversion of IP 5 to inositol pyrophosphates modulates INO1 transcription.

The method and application of importing GIS data to AnyLogic (2011)

AnyLogic is a kind of excellent software of complex system simulation. It can more accurately reflect the information of real life and expand the application of complex system simulation by adding GIS map as agent's environment. But, there are some problems at present when importing GIS data to AnyLogic. Based on the analysis of differences between ordinary engineering drawing and GIS vector diagram, this paper puts forward a method to import GIS data by data conversion, and meanwhile realizes some functions of GIS in AnyLogic. Take Shijingshan District as a case, we verify the feasibility of the method and also discuss the agent settings after adding the data. This paper provides a new way for the Agent based modeling method while AnyLogic combines with GIS.
FVIII stabilization: VWF D′D3 will do (2014)

In this issue of Blood, Yee et al1 have demonstrated that expression or infusion of a truncated von Willebrand factor (VWF) fragment containing the factor VIII (FVIII)-binding D′D3 region of VWF is sufficient to stabilize endogenous FVIII levels in VWF-deficient mice. In the absence of the carrier function of VWF, FVIII is susceptible to rapid proteolysis and clearance resulting in markedly reduced plasma levels of FVIII that contribute to a bleeding diathesis.

Structural analysis of heme proteins: implications for design and prediction (2011)

Our analysis revealed that heme binding pockets show special features and that most of the heme proteins undergo small conformational changes after heme binding, suggesting the apo structures can be used for structure-based heme protein prediction and as scaffolds for future heme protein design.
Laser Method for Synthesis and Processing of Continuous Diamond Films on Nondiamond Substrates (1991)

A laser method based upon carbon ion implantation and pulsed laser melting of copper has been used to produce continuous diamond thin film. Carbon ions were implanted with ion energies in the range of 60 to 120 keV, and doses of 1.0 x 10(18) to 2.0 x 10(18) ions cm(-2). The ion-implanted specimens were treated with nanosecond excimer laser pulses with the following parameters: energy density, 3.0 to 5.0 J cm(-2); wavelength, 0.308 microm; pulse width, 45 nanoseconds. The specimens were characterized with scanning electron microscopy (SEM), x-ray diffraction, Rutherford backscattering/ion channeling, Auger, and Raman spectroscopy. The macroscopic Raman spectra contained a strong peak at 1332 cm(-1) with full width at half maximum of 5 cm(-1), which is very close to the quality of the spectra obtained from single-crystal diamond. The selected area electron diffraction patterns and imaging confirmed the films to be defect-free single crystal over large areas of up to several square micrometers with no grain boundaries. Low voltage SEM imaging of surface features indicated the film to be continuous with presence of growth steps.
Surface modification of recording electrodes (2013)

Waterborne Polyurethanes (PUs) are a family of polymers that contains urethane linkages synthesized in an aqueous environment and are thus free of organic solvents. Recently, waterborne PUs have been extensively studied for biomedical applications because of their biocompatibility. The present work investigates the following: (1) the impact on electrical performance of electrode materials (platinum and silicon) modified chemically by a layer of waterborne PU, and (2) the behavior of rat cardiac fibroblasts and rat cardiomyocytes when in contact with an electrode surface. Diisocyanate and poly(caprolactone diol) were the main reagents for producing PUs. The electrochemical impedance of the electrode/electrolyte interface was accessed by electrochemical impedance spectroscopy. The cellular viability, proliferation, and morphology changes were investigated using an MTT assay. Cardiomyocyte adherence was observed by scanning electron microscopy. The obtained surface was uniform, flat, and transparent. The film showed good adhesion, and no peeling was detected. The electrochemical impedance decreased over time and was influenced by the ionic permeability of the PU layer. The five samples did not show cytotoxicity when in contact with neonatal rat cells.
Defining the common subtypes of HLA A9, A10, A28 and A19 by use of ARMS/PCR (1993)

We describe sequence-specific primer (SSP) combinations for use in a one-step polymerase chain reaction (PCR) typing system to determine HLA-A locus subtypes of A9 (A23, A24), A10 (A25, A26, A43), A28 (A*6801, A*6802, A*6901) and A19 (A*2901, A*2902, A*3001, A*3002, A31, A32, A33) from genomic DNA. SSP's were designed on the basis of the amplification refractory mutation system (ARMS) in which a mismatch at the 3' residue inhibits non-specific amplification. The SSP combinations described extend our low-resolution typing system, to provide a high-definition typing of the HLA-A locus.
Microbial Contamination of Air in Piggeries with Minimal Morbidity (1978)

Microbial contamination of air was compared in conventional piggeries and in piggeries with minimal morbidity. The comparison proved, particularly with piglets reared to 4-5 weeks of age, the effectivity of devices protecting from exogenous microfiora such as strict "all in all out" system, careful disinfection of compartments, and, high personal hygiene of staff. In the course of rearing piglets from 5 weeks upwards, some deterioration of air contamination by exogenous and endogenous microbes occurred in piggeries with conventional feeding and housing where the strict "all in all out" system was not held. Best results were obtained in rearing houses with weanlings kept in cages where a mean of 2.2 x 10' microbes/I m a were found on MPA. Microbes growing on mannitol agar with salt represented 7.4 x 10 2 , on Endo agar 7.7 x 10 2 and 1.9 x 10 2 respectively, on blood agar with crystal violet 1.8 x 10" on Czapek-Dox agar 3.6 x 10' microbes/I m S air.

Pearl-Necklace-Like Chain Conformation of Hydrophobic Polyelectrolyte:  a SANS Study of Partially Sulfonated Polystyrene in Water (2007)

The form factor of partially sulfonated polystyrene PSSNa (degree of sulfonation f = 1, 0.72, 0.64, and 0.36), at polymer concentrations 0.17 and 0.34 M, without or with added salt (0 M, 0.34 M, and 0.68 M), is measured by small-angle neutron scattering using the zero average contrast method. The total scattering function is also measured, allowing us to extract the distinct interchain function and an apparent structure factor. The main result is the behavior of the form factor, which shows contributions of spherical entities as well as extended chain parts. This is striking for 0.64, while for f = 0.36 the sphere contribution is more dominant. The conformation does not depend on polymer concentration. When salt is added, the sphere sizes do not vary, but the contribution attributed to the stretched parts does vary very much like for fully sulfonated PSSNa. Discussion of the interchain contribution permits to establish the level of interpenetration: solutions are interpenetrated for f = 0.64, and at the limit for f = 0.36. The theoretical pearl necklace model appears very suitable to modeling the results. Comparisons are made with the analytical calculation and simulation data of a pearl necklace. While the respective roles of Rayleigh transition, heterogeneous architecture, and strong hydrophobicity of non sulfonated PS monomers remain under discussion, the data give an accurate three-dimensional image of the pearl necklace in solution.
Wireless Communications With RF-Based Energy Harvesting: From Information Theory to Green Systems (2017)

Harvesting energy from ambient environment is a promising technology to free electronic devices from electric wire and lifetime-limited battery, which have found many significant applications in sensor networks and body-area networks. This paper investigates the fundamental limit of information transmission in a wireless communication system with RF-based energy harvesting, where a master node acts both the information source and the energy source for a child node, while only information is transmitted back from the child node to the master node. In the systemic level viewpoint, we jointly investigate the two-way information transmission between the two nodes under the unique external power supply constraint at the master node. In particular, three typical receivers are considered, including the optimum receiver, the orthogonal receiver and the power splitting receiver. We explicitly characterize the achievable capacity-rate region and discuss the effect of signal processing power consumption at the child node. We also derive the boundary of the achievable capacity-rate region, which illustrates the most energy-efficient transmission strategy of the system. Simulation results confirm the substantial gain of employing capacity-rate region achieving transmission strategies and employing optimal receivers. Moreover, we present a typical application of our results, where the required transmit power is minimized to green the system.
Generalizing Interactive Backpropagating Refinement for Dense Prediction (2021)

As deep neural networks become the state-of-the-art approach in the field of computer vision for dense prediction tasks, many methods have been developed for automatic estimation of the target outputs given the visual inputs. Although the estimation accuracy of the proposed automatic methods continues to improve, interactive refinement is oftentimes necessary for further correction. Recently, feature backpropagating refinement scheme (f-BRS) has been proposed for the task of interactive segmentation, which enables efficient optimization of a small set of auxiliary variables inserted into the pretrained network to produce object segmentation that better aligns with user inputs. However, the proposed auxiliary variables only contain channel-wise scale and bias, limiting the optimization to global refinement only. In this work, in order to generalize backpropagating refinement for a wide range of dense prediction tasks, we introduce a set of G-BRS (Generalized Backpropagating Refinement Scheme) layers that enable both global and localized refinement for the following tasks: interactive segmentation, semantic segmentation, image matting and monocular depth estimation. Experiments on SBD, Cityscapes, Mapillary Vista, Composition-1k and NYU-Depth-V2 show that our method can successfully generalize and significantly improve performance of existing pretrained state-of-the-art models with only a few clicks.
