An advanced missile warning processing suite (2008)

Effective missile warning and countermeasures remain an unfulfilled goal for the Air Force and others in the DOD community. To make the expectations a reality, newer sensors exhibiting the required sensitivity, field of regard, and spatial resolution are being developed and transitioned. The largest concern is in the first stage of a missile warning system: detection, in which all targets need to be detected with a high confidence and with very few false alarms. Typical fielded sensors are limited in their detection capability by either lack of sensitivity or by the presence of heavy background clutter, sun glints, and inherent sensor noise. Many threat environments include false alarm sources like burning fuels, flares, exploding ordinance, arc welders, and industrial emitters. Multicolor discrimination has been shown as one of the effective ways to improve the performance of missile warning sensors, particularly for heavy clutter situations. Its utility has been demonstrated in multiple demonstration and fielded systems. New exploitations of background and clutter spectral contents, coupled with advanced spatial and temporal filtering techniques, have resulted in a need to have a new baseline algorithm on which future processing advances may be judged against. This paper describes the AFRL Suite IIIc algorithm chain and its performance against long-range dim targets in clutter.
Increased expression of the homeostatic chemokines CCL19 and CCL21 in clinical and experimental Rickettsia conoriiinfection (2014)

Our findings suggest that the CCL19/CCL21/CCR7 axis is up-regulated during R. africae and in particular during R. conorii infection, which may potentially contribute to the pathogenesis of these disorders.
The relationship between obsessive‐compulsive symptoms and PARKIN genotype: The CORE‐PD study (2014)

First, a significant association was found between PARKIN mutation status and obsessive-compulsive symptom level in both PD and asymptomatic patients, suggesting that OCS might represent an early non-motor dopamine-dependent feature. Second, irrespective of disease status, heterozygotes were significantly different from noncarriers, suggesting that PARKIN heterozygosity may contribute to phenotype. © 2014 International Parkinson and Movement Disorder Society.
A Transparent and Flexible Polymer-Fabric Tissue UWB Antenna for Future Wireless Networks (2016)

A flexible and transparent ultrawideband (UWB) antenna that uses a transparent conductive fabric tissue on a polydimethylsiloxane (PDMS) substrate is presented in this letter. The fabric tissue is integrated onto the PDMS having a thickness of 2 mm to produce an efficient UWB antenna. To achieve this, first, a sheet of the conductive fabric tissue was attached to the upper and lower surface of a PDMS layer to produce a fabric panel with three layers. Then, the radiating elements were formulated precisely in the upper and lower layers, using a laser machine. The measured transparency of the fabric tissue and the PDMS can attain a value of more than 70% and 90%, respectively, in the visible spectrum. The antenna operates at a 2.2-25-GHz band with average efficiency of over 75% throughout the operating band and shows satisfactory gain and a good radiation pattern. It performs well under bending conditions, as ensured by its measurements. The proposed antenna's optical transparency, mechanical flexible properties, and seamless integration process indicate its promising potential in a variety of transparent antenna applications for future wireless networks.
Volatile organic compounds and aerosols in air: Development of sampling methods, chemical analysis and modelling (1999)

Emissions of traffic contribute to a large extent to the health effects of air pollution.It is still uncertain how much of these effects are due to aerosols and whether chemical composition or just the number of particles are important.The interactions between gaseous and particulate matter in the atmosphere requires that scientific studies will have to deal with those interdependencies.Computer models will be very useful here, but these models must be evaluated using measurements.Good and useful measurements to test these models are scarce.Sampling and analysis of organic compounds in gaseous and particulate phase in the atmosphere is a complex job.To study the relative importance of the possible processes in the atmosphere in the first half hour after emission of organic compounds, measurements and computer models to test (the gaps in) our knowledge are required.In this report the analytical and sampling methods deployed or developed to do this are described.During an experiment along the A9 highway the sampling and analysis techniques were tested.Within certain limitations all methods deployed are adequate for use in further research.Modelling tools are developed and adopted to describe the dispersion process, chemical reactions, deposition and aerosol processes.
Essentially No Barriers in Neural Network Energy Landscape (2018)

Training neural networks involves finding minima of a high-dimensional non-convex loss function. Knowledge of the structure of this energy landscape is sparse. Relaxing from linear interpolations, we construct continuous paths between minima of recent neural network architectures on CIFAR10 and CIFAR100. Surprisingly, the paths are essentially flat in both the training and test landscapes. This implies that neural networks have enough capacity for structural changes, or that these changes are small between minima. Also, each minimum has at least one vanishing Hessian eigenvalue in addition to those resulting from trivial invariance.
Enhanced Network-State Estimation using Change Detection (2006)

This paper presents the concept of change detection for filter-based network-state estimation. This could be useful in various contexts; two examples are network management and adaptive applications. In particular, it is shown that the performance of available-bandwidth estimation can be significantly enhanced by employing a change-detection technique in conjunction with a filter-based estimator. By using filter-based approaches, it is possible to track the state of communication systems, and to estimate network properties in real-time. A virtue of filter-based methods is the ability to enhance the estimation performance by combining them with change detection. This makes it feasible to overcome the tradeoffs regarding speed of adaptation to changes versus stable estimation. We discuss filtering and change detection in general, and illustrate the power of this combination with the filter-based available-bandwidth estimator BART enhanced by the light-weight change-detection test CUSUM
Shallow Junction Ion Implantation in Ge and Associated Defect Control (2006)

We have studied implant-induced damage, defect annealing, and recrystallization of B, Ga, P, As, and Sb introduced in Ge by ion implantation at high doses, such that dopant chemical concentrations are above the corresponding solubility in Ge, with energies that target about 100-nm junction depths. It is shown that the amount of damage induced in the Ge lattice increases with the mass of the implanted ion, as expected. Implanted B produces local amorphous regions, although crystalline Ge zones are present in the implanted layer. P is a self-amorphizing ion, creating a continuous amorphous layer during implantation. However, a low thermal budget is sufficient to fully regrow the amorphous layer, without evidence of residual extended defects, as evaluated by cross-sectional transmission electron microscopy. Conversely, high concentrations of As cause a significant decrease of the regrowth rate of the damaged layer during rapid thermal annealing in the 400–600°C range studied. Finally, high-dose implantation of heavy ions such as Sb induces dramatic morphologic changes in Ge that are not recovered by post-implant rapid thermal annealing.
P2‐148: Involvement of 9G8 in alternative splicing of tau exon 10 (2008)

Tau protein is the major neuronal microtubule-associated protein. Its normal function is to promote microtubule assembly and stabilize microtubules. In Alzheimer's disease (AD) brain, tau is abnormally hyperphosphorylated and aggregates into neurofibrillary tangles in the neuronal cell bodies. In adult human brain, six tau isoforms are expressed from a single gene by alternative splicing of exons (E) 2, 3, and 10. Inclusion and exclusion of E10 generates tau with either four or three microtubule-binding repeats (3R- or 4R-tau), respectively. In normal adult human brain, the levels of 3R-tau and 4R-tau are almost equal. Mutations within E9, E10, and intron 10 affect E10 splicing and disturb the normal balance of 3R/4R tau ratio, leading to frontotemporal dementia with Parkinsonism linked to chromosome 17 (FTDP-17). 9G8, also named SRp30, is a splicing factor that belongs to the SR protein family and is involved in alternative splicing of many genes. In order to determine if Dyrk1A (dual-specificity tyrosine-phosphorylated and regulated kinase 1A), a proline/arginine-directed serine/threonine kinase, has interaction with 9G8 and phosphorylates 9G8 in vitro, GST-pull down, co-immunoprecipitation, co-localization and radioautography were used in this study. Using RT-PCR, we study whether Dyrk1A regulates the alternative splicing of tau exon 10 by having interaction with 9G8. Overexpression of 9G8 in cells facilitated the exclusion of tau E10, resulting in 3R up-production. Dyrk1A interacted with 9G8 and phosphorylated it efficiently in vitro. Overexpression of Dyrk1A inhibited the exclusion of E10 induced by 9G8. These results indicated that Phosphrylation by Dyrk1A probably inhibited 9G8-mediated tau E10 exclusion.

Optimisation of the DCSBD roll-to-roll treatment of LLDPE/PA tubular foil using rollers of different electrical resistance (2021)

This study aimed to optimise the diffuse coplanar surface barrier discharge (DCSBD) roll-to-roll (R2R) treatment of multi-layer tubular foil using several types of rollers differing in material resistance. Multi-layer tubular foils are used as casings in the meat industry. The effect of ambient air plasma generated by coplanar and volume dielectric barrier discharge on the surface characteristics of tubular foil formed from outside by polyamide had already been studied previously [1]. Subsequently, the influence of R2R plasma treatment on the surface properties of tubular foil's inner layer formed with linear low-density polyethylene (LLDPE) was studied. During the roll-to-roll treatment, the plasma acts from outside of the tubular foil, whereas the inside surface of the tubular foil is affected by plasma as well in dependence on the material of the roller. The utility model “Device for plasma treatment of tubular foils” was registered based on this finding [2]. It has been experimentally verified that a non-conductive roller constructed from plastic does not allow the surface discharge to be superimposed by microfilaments generated perpendicular to the film surface. This finding clarified the different effects of plasma treatment achieved using plastic and metal-rubber roller on the surface properties of LLDPE foil. Applied exposure times of DCSBD treatment were in the range of 0.5–2 seconds. Evident wettability improvement of LLDPE foil surface after the plasma treatment was observed with the naked eye, while the pristine LLDPE foil surface repelled water solution of methylene blue (Fig. 1). The increase in peel resistance in the case of 0.5 s exposure time when comparing plastic and metal-rubber roller was three times higher for the second one. Peel resistance of untreated LLDPE foil was so low that it was unmeasurable. Best results were obtained for 2 s plasma exposure, where the peel resistance achieved using the metal-rubber roller was 31 % higher than for the plastic roller. The specific electrical resistance of a standard metal roller covered with rubber on the surface corresponds to 238.5 G?cm2, whilst the value for an optimised metal-rubber roller is 7.5 M?cm2. Significantly better film-to-meat adhesion was observed for the DCSBD plasma unit using a metal-rubber roller with the specific resistance of 7.5 M?cm2 than for the metal-rubber roller with the resistance of 238.5 G?cm2. This result could be attributed to the low specific resistance of the roller, which means higher conductivity when the surface discharge is superimposed by microfilaments generated perpendicular to the film surface.

The Reduction of Blocky Artifacts in Conditional Replenishment Algorithm for SC-MMH 3DTV Systems (2017)

조건부대체 알고리즘은 ATSC의 융합형 3DTV 표준인 SC-MMH 시스템의 화질을 개선하는 방법으로서 ATSC에 의해서 표준화되었다. SC-MMH 시스템에서는 양안식 스테레오 영상을 구성하는 기준영상과 부가영상의 해상도 및 부호화 방식이 서로 다르게 정해진다. 3D 영상을 합성하기 위해 해상도가 낮은 부가영상을 확장함에 있어서 조건부대체 알고리즘을 적용하면 약간의 부가 정보를 추가함으로써 3D 영상의 화질이 대폭 개선된다. 이 과정에서 부가 정보는 쿼드트리 구조의 가변 크기 블록 단위로 처리되기 때문에 확장된 부가영상에는 시각적으로 거슬리는 블록화 현상이 발생할 수 있다. 본 논문에서는 SC-MMH 시스템의 수신기 측면에서 조건부대체 알고리즘에 의한 블록화 현상이 발생하는 경우를 분석하고 가변크기의 블록에 사용가능한 디블록킹 필터를 적용함으로써 블록화 현상을 효과적으로 억제할 수 있음을 실험을 통해 검증하였다. CRA(Conditional Replenishment Algorithm) was proposed to improve the visual quality of SC-MMH(Service Compatible 3DTV using Main and Mobile Hybrid delivery) which is a kind of hybrid 3DTV system and has been standardized by ATSC. In SC-MMH system, reference view and additional view may have different resolutions and/or encoding methods. To reconstruct 3D view, additional view needs to be enlarged as same as reference view. Although the performance of CRA is quite satisfactory, there may exist some blocky artifacts in the enlarged view since it adopts block-shaped processing unit with quad-tree structure. In this paper, we analyze the main causes of blocky artifacts in CRA and show these artifacts can be successfully suppressed by applying the deblocking filter at receiver side.
[Expression, purification of recombinant human cryptochrome I and its application in preparation of protective agent for radiotherapy]. (2015)

Radiotherapy is a treatment for cancer with undesired by-effects. In order to develop a new radiation protective agent that could reduce the by-effects, we tried to express and purify human cryptochrome 1 (hCRY1). The coding sequence of hCRY1 was inserted into prokaryotic expression plasmid pET28a(+), and this protein was purified from Escherichia coli BL21(DE3) after IPTG induction, ultrasonication, inclusion body dissolution, gradient dialysis, nickel column purification and ultrafiltration. The yield of hCRY1 in 1 L E. coli culture (LB medium) was about 10-15 mg. The radiation protective efficiency of hCRY1 was monitored by detecting X-ray-induced H2A.X foci in HaCaT cells. The results of immunofluorescence show that hCRY1 significantly reduces X-ray stimulated DNA damage response. The apoptosis of HaCaT cell was also detected, and the repression of H2A.X foci formation was not due to hCRY1's cytotoxity. All these data suggest a potential application of recombinant hCRY1 as a protective agent for radiotherapy.
Energy-Efficient Module applied with Run Length Coding for Wireless Sensor Networks (2008)

In wireless sensor networks, sensor nodes are generally battery-operated. The efficient use of energy is very important, as the battery of sensor nodes cannot be recharged after deployment. The energy can be saved by placing the radio in the low power sleep mode, when data aren't transmitted or received. So, our goal is to keep minimizing energy consumption of a limited battery of sensor node and to prolong the network life as long as possible by maximizing the time of low power sleep mode. In this paper, to achieve these aims, we discuss the design of a new module that has the efficient use of energy by eliminating the major waste cause such as the sensing data equal to previous sensing data in monitoring environment periodically. So, we apply run length coding and make C-module (compression-module). C-Module residing between the transport layer and application layer has the efficient use of energy by reducing traffics. The performance of C-module is studied by simulation and is compared to that of well known 802.11, S-MAC, C-module cooperating with 802.11 and C-module cooperating with S-MAC. Finally, we prove that using C-module has more improved results than not using C-module in the aspect of efficient use of energy through NS-2 simulator.
Efficient single-chip implementation of SHA-384 and SHA-512 (2003)

The rapid developments in the communications industry over the last decade have led to an escalation in the amount of sensitive data being transmitted over the Internet. This has resulted in an increased awareness of the need to provide security measures. Authentication is one such security measure. A novel highly efficient single-chip hardware design of the SHA-384 and SHA-512 authentication algorithms is described in this paper. The compact implementation achieves a throughput of 479 Mbits/sec utilising a shift register design approach and look-up tables (LUTs). This is believed to be the first SHA-384/SHA-512 hardware implementation to be reported in the literature.
Efficient user Scheduling under Low Rate Feedback for Correlated MIMO Broadcast Channels (2008)

This paper investigates the scheduling of user signals in MIMO systems with spatially correlated channels. By maximizing an upper bound of the sum capacity, we propose a scheduling scheme which requires only a single scalar feedback from each receiving user. To further reduce the need for user information feedback and better explore the spatial correlation information, a more efficient scheduling method is also developed. This new approach only requires a 1-bit indicator from each user and selects users according to the slowly varying MIMO channel correlation information. Numerical results verify the effectiveness of our proposed schemes.
Single-Shot Multiwavelength Imaging of Laser Plumes (1998)

A novel optical approach to single-shot chemical imaging with high spectroscopic resolution is described with the use of a prototype dimension-reduction fiber-optic array. Images are focused onto a 30 × 20 array of hexagonally packed 250 μm o.d. f/2 optical fibers that are drawn into a 600 × 1 distal array with specific ordering. The 600 × 1 side of the array is imaged with an f/2 spectrograph equipped with a holographic grating and a charge-coupled device (CCD) camera for spectral analysis. Software is used to extract the spatial/spectral information contained in the CCD images and de-convolute them into wavelength-specific reconstructed images or position-specific spectra that span a 190 nm wavelength space. “White light” zero-order images and first-order spectroscopic images of laser plumes have been reconstructed to illustrate proof-of-principle.

Risk Factor Analyses for Macrovascular Complication in Nonobese NIDDM Patients: Multiclinical Study for Diabetic Macroangiopathy (MSDM) (1996)

To examine the characteristic features of risk factors for macroangiopathy (MA) in nonobese Japanese NIDDM patients, 899 NIDDM patients with and without MA were registered from 40 facilities. Of these, 386 subjects were identified as having any form of MA (total MA); these included 211 with ischemic heart disease (IHD), 163 with cerebrovascular disease (CVD), and 77 with peripheral vascular disease (PVD). Univariate analyses revealed the following common risk factors for total MA, IHD, CVD, and PVD: age, hypertension, systolic blood pressure (sBP) or diastolic blood pressure (dBP), duration of diabetes, diabetic microangiopathy (retinopathy, nephropathy, and neuropathy), low HDL cholesterol level, and higher LDL cholesterol/HDL cholesterol ratio. Additional significant risk factors for specific conditions were also identified, respectively, as male sex for total MA, IHD, and PVD, smoking for IHD and PVD, and high fasting plasma glucose level for total MA and CVD. With stepwise multivariate logistic regression analysis, older age, duration of diabetes, smoking, and low LDL cholesterol/HDL cholesterol ratio were identified as significant and independent risk factors for total MA, IHD, CVD, and PVD. Other risk factors identified were high dBP for IHD, CVD, and PVD, high sBP for total MA, and low BMI for PVD. These results clearly demonstrated that duration of diabetes, smoking, hypertension, and dyslipidemia are major risk factors for MA in NIDDM patients. Since the mean BMI was similar for both groups (approximately 23 kg/m2) and there were no significant differences in immunoreactive insulin levels before and after 75-g oral glucose challenge testing, obesity and hyperinsulinism at the time of the analyses were not considered to play an important role for the pathogenesis of MA in Japanese NIDDM patients. By using the chi 2 test, cutoff points were determined for six of the most commonly measured risk factors. The cutoff point was the level beyond which a significantly higher prevalence of MA occurred. The cutoff points (rounded slightly upward in some cases) for fasting plasma glucose, sBP, dBP, serum total cholesterol level, serum triglyceride level, and BMI were 140 mg/dl, 140 mmHg, 80 mmHg, 180 mg/dl, 120 mg/dl, and 23 kg/m2, respectively. When these cutoff points were used as control criteria, the prevalence of MA was significantly lower in subjects whose risk factor measurements remained under the proposed control criteria for four or more of the six variables. In conclusion, in nonobese NIDDM patients, age, hypertension, and dyslipidemia were found to be risk factors for MA. Duration of diabetes was also demonstrated as an independent risk factor, indicating the close association of deranged glucose metabolism with the pathogenesis of MA in NIDDM patients. It seems to be crucial to control these risk factors for the prevention of MA in NIDDM patients.
