Performance evaluation of asphalt mixtures containing high-RAP binder content and bio-oil rejuvenator (2019)

The objective of this study was to conduct a laboratory-based research study that evaluated the performance of asphalt mixtures prepared with date seed oil (DSO) modified binders containing different amounts of Reclaimed Asphalt Pavement (RAP) binder varying from 20 to 40%. To this end, moisture susceptibility, rutting performance, stiffness modulus and fatigue resistance of the mixtures were assessed using Modified Lottman (AASHTO T283), Wheel Tracking Test (WTT), Indirect Tensile Stiffness Modulus (ITSM) and four-point beam fatigue, respectively. Regression models were provided to estimate fatigue life of the mixes. The results showed that moisture susceptibility of the mixes was slightly influenced by DSO content. Rutting performance of the mixes was deteriorated, while the addition of DSO improved fatigue life of the specimens containing 20% RAP up to 15%. However, in order to employ 40% or more of RAP binder, other alternatives should be considered.
Multi-objective Genetic Algorithms: Problem Difficulties and Construction of Test Problems (1999)

In this paper, we study the problem features that may cause a multi-objective genetic algorithm (GA) difficulty in converging to the true Pareto-optimal front. Identification of such features helps us develop difficult test problems for multi-objective optimization. Multi-objective test problems are constructed from single-objective optimization problems, thereby allowing known difficult features of single-objective problems (such as multi-modality, isolation, or deception) to be directly transferred to the corresponding multi-objective problem. In addition, test problems having features specific to multi-objective optimization are also constructed. More importantly, these difficult test problems will enable researchers to test their algorithms for specific aspects of multi-objective optimization.
Real-time image processing for label-free enrichment of Actinobacteria cultivated in picolitre droplets (2013)

The majority of today's antimicrobial therapeutics is derived from secondary metabolites produced by Actinobacteria. While it is generally assumed that less than 1% of Actinobacteria species from soil habitats have been cultivated so far, classic screening approaches fail to supply new substances, often due to limited throughput and frequent rediscovery of already known strains. To overcome these restrictions, we implement high-throughput cultivation of soil-derived Actinobacteria in microfluidic pL-droplets by generating more than 600,000 pure cultures per hour from a spore suspension that can subsequently be incubated for days to weeks. Moreover, we introduce triggered imaging with real-time image-based droplet classification as a novel universal method for pL-droplet sorting. Growth-dependent droplet sorting at frequencies above 100 Hz is performed for label-free enrichment and extraction of microcultures. The combination of both cultivation of Actinobacteria in pL-droplets and real-time detection of growing Actinobacteria has great potential in screening for yet unknown species as well as their undiscovered natural products.
T cell-intrinsic IL-1R signaling licenses effector cytokine production by memory CD4 T cells (2018)

Innate cytokines are critical drivers of priming and differentiation of naive CD4 T cells, but their functions in memory T cell response are largely undefined. Here we show that IL-1 acts as a licensing signal to permit effector cytokine production by pre-committed Th1 (IFN-γ), Th2 (IL-13, IL-4, and IL-5) and Th17 (IL-17A, IL-17F, and IL-22) lineage cells. This licensing function of IL-1 is conserved across effector CD4 T cells generated by diverse immunological insults. IL-1R signaling stabilizes cytokine transcripts to enable productive and rapid effector functions. We also demonstrate that successful lineage commitment does not translate into productive effector functions in the absence of IL-1R signaling. Acute abrogation of IL-1R signaling in vivo results in reduced IL-17A production by intestinal Th17 cells. These results extend the role of innate cytokines beyond CD4 T cell priming and establish IL-1 as a licensing signal for memory CD4 T cell function.
Contrast research on the soil moisture environment between artificial coconut grove and eucalyptus plantation in Danzhou Forest Farm, Hainan (2012)

Eucalyptus planting area is larger and contiguous distribution in Danzhou Forest Farm, lying in the west of Hainan, China. 4 years old eucalyptus forest and artificial coconut grove, the space adjacent and the natural conditions similar, were selected as comparative research plots. Study on the soil moisture environment differences of eucalyptus plantation and artificial coconut grove by continuous field-point sampling. The results show that: 1) The soil surface, subsurface and deep average soil moisture content are 6.66%, 9.71% and 9.67% of eucalyptus forests plots, and which are 7.19%, 10.04% and 11.31% of coconut grove plots. 2) The average soil moisture contents of eucalyptus forest plots are respectively 0.84%, 0.67% and 1.02% less than coconut grove plots in the whole, dry and wet seasons. 3) The annual range of variation of eucalyptus plantation's soil moisture is 3.77%, and that of artificial coconut grove is 3.18%. In similar natural conditions, eucalyptus forests' average soil moisture contents are less than coconut grove. The soil moister difference between the two plots is 0.57% in wet season, and 1.16% in dry season. Which mean that eucalyptus plantation consumes more soil moisture than artificial coconut grove, and eucalyptus planting may have a negative ecological impact on soil moisture environment?
Trough waveguide dual-frequency antenna (1972)

A new type of dual-frequency antenna using a hollow-fin trough waveguide is described. The hollow fin is used as a <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">TE_{10}</tex> mode waveguide with sidewall radiating elements. These Sidewall radiating elements constitute the high-frequency section of the antenna. The low-frequency section consists of a thick hollow-fin trough waveguide antenna. The attenuation due to radiation and waveguide wavelength of the trough waveguide section are analyzed. This analysis shows good agreement with experimental measurements. Existing data may be used as a guide in the design of the high-frequency section of this antenna, and the data presented may be used as a guide in the design of the low-frequency section.
Calculation of moments of complex Wishart and complex inverse Wishart distributed matrices (2000)

The calculation of moments of complex Wishart and complex inverse Wishart distributed random matrices is addressed. In applications such as radar, sonar or seismics, complex Wishart and complex inverse Wishart distributed random matrices are used to model the statistical properties of complex sample covariance matrices and complex inverse sample covariance matrices, respectively. Moments of these random matrices are often needed, for example, in studies of the asymptotic properties of parameter estimates. A derivation of the probability density function of complex inverse Wishart distributed random matrices is given. Furthermore, strategies are outlined for the calculation of the moments of both complex Wishart and complex inverse Wishart distributed matrices.
Protective effect of taurine and quercetin against renal dysfunction associated with the combined use of gentamycin and diclofenac. (2008)

The potential protective effects of taurine and quercetin against gentamycin (GM)/diclofenac (DC) combined nephrotoxicity were investigated in rats. The results showed that administration of DC alone at an oral dose of 5 mg/kg b.wt/day for 28 days had no significant effect on the measured parameters, except for marked increase in urinary uronic acid excretion. Administration of GM alone at a dose of 100 mg/kg b.wt/day i.p. for 8 days resulted in obvious nephrotoxicity. Combined GM-DC treatment led to the most pronounced nephrotoxicity, as indicated by greater elevations in serum urea, creatinine and urinary N-acetyl-beta-D-glucosaminidase (NAG), together with severe depression of renal cortical Na , K+-ATPase, compared to GM-treated group. Moreover, only combined treatment resulted in significant decrease in urinary potassium and renal cortical glutathione peroxidase (GSHPx), together with an increase in renal cortical lipid peroxidation products (LPOs). Co-administration of taurine or quercetin normalized creatinine clearance and ameliorated the elevations in urinary proteins, uronic acids, NAG and renal cortical LPOs in GM/DC treated rats. The study justifies the use of taurine and quercetin as renoprotective agents against the nephrotoxicity caused by GM/DC therapy.
Mechanical sutures in surgery (1973)

Abstract Following the original introduction of an automatic stapling instrument producing B-form staples by de Petz (1924, 1927), there has been derived from the very important first generation of Soviet stapling instruments a second generation of American stapling instruments characterized by: (1) the use of preloaded, pre-sterilized, and disposable staple cartridges; (2) the adaptability of one instrument to a variety of cartridges for use in a variety of tissues and operative situations; (3) the transfer from the instrument itself to the disposable cartridge of delicate and fragile moving parts simplifying the maintenance and operation of instruments. The instruments have found wide and satisfactory application in numerous areas of thoracic, vascular, gastro-intestinal, and gynaecological surgery.
Atomic layer epitaxy of III-V compounds: chemistry and applications (1992)

Atomic layer epitaxy (ALE) of III-V compounds is addressed, with particular focus on ALE by chloride source gases of group III elements and hybrids of group V elements. A self-limiting growth mechanism in ALE is the most significant advantage over other epitaxial methods. To realize this mechanism, selections of source gases and the reactor gases and the reactor design are described. The chemistry and growth kinetics of ALE, which also provide interesting information for understanding other vapor phase epitaxy (VPE) processes, are discussed, and a model of the self-limiting growth mechanism for chloride ALE is proposed. As a promising application of ALE, the growth of fine structures using sidewall epitaxy and selective area growth is demonstrated. Prospects for the future are briefly discussed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Effects of Indomethacin, Nimesulide, and Diclofenac on Human MG-63 Osteosarcoma Cell Line (2011)

Nonsteroidal anti-inflammatory drugs (NSAIDs) are among the most widely prescribed drugs worldwide and serve as treatment of some degenerative inflammatory joint diseases. The aim of the present study was to investigate the influence of different concentrations of three NSAIDs on cell proliferation, differentiation, antigenic profile, and cell cycle in the human MG-63 osteosarcoma cell line, incubated for 24 hr. All NSAIDs had an inhibiting effect on osteoblastic proliferation. Treatments for 24 hr had small but significant effects on the antigenic profile. No treatment altered osteocalcin synthesis. Indomethacin and nimesulide treatments arrested the cell cycle at G(0)/G(1). These results suggest that indomethacin, nimesulide, and diclofenac appear to have no effects on osteocalcin synthesis and a slight effect on the antigenic profile. They may delay bone regeneration due to their inhibiting effect on osteoblast growth. Therefore, these drugs should only be used in situations that do not require rapid bone healing.
Studies on Stereospecific Formation of <i>P</i> -Chiral Internucleotide Linkage: Synthesis of all- <i>Rp</i> and all- <i>Sp</i> Methylphosphonate Pentanucleotide d(MMTrA <sub>PMe</sub> T <sub>PMe</sub> T <sub>PMe</sub> C <sub>PMe</sub> TAc) via Grignard Activated Coupling (1997)

Synthesis of stereoregular 3',5'-protected all-Rp and all-Sp methylphosphonate heterooligonucleotides d(MMTrAPMeTPMeTPMeCPMeTAc) (12) complementary to the fragment of HIV-1 splicing acceptor site was achieved via stereo-controlled formation of internucleotide linkage. The coupling was based on the transesterification of P-stereodefined monomer type of 5'-O-monomethoxytrityl-2'-O-deoxynucleoside 3'-O-[O-(4-nitrophenyl)methylphosphonate]. The nucleophile was a t-butylmagnesium chloride activated 5'-terminal hydroxyl function of the growing oligonucleotide chain. This and other P-homochiral oligomers will be used as building blocks for the synthesis of biologically significant, longer stereoregular oligonucleotides.
Dosimetric characterization and image quality evaluation of the AIRO mobile CT scanner (2015)

Radiation dose and image quality from a recently introduced mobile CT imaging system are presented. Radiation dose was measured using a conventional 100 mm pencil ionization chamber and CT polymethylmetacrylate (PMMA) body and head phantoms. Image quality was evaluated with a CATPHAN 500 phantom. Spatial resolution, low contrast resolution, Modulation Transfer Function (MTF), and Normalized Noise Power Spectrum (NNPS) were analyzed. Radiation dose and image quality were compared to those from a multi-detector CT scanner (Siemens Sensation 64). Under identical technique factors radiation dose (mGy/mAs) from the AIRO mobile CT system (AIRO) is higher than that from a 64 slice CT scanner. Based on MTF analysis, both Soft and Standard filters of the AIRO system lost resolution quickly compared to the Sensation 64 slice CT. The Siemens scanner had up to 7 lp/cm for the head FOV and H40 kernel and up to 5 lp/cm at body FOV for the B40f kernel. The Standard kernel in the AIRO system was evaluated to have 3 lp/cm and 4 lp/cm for the body and head FOVs respectively. NNPS of the AIRO shows low frequency noise due to ring-like artifacts which may be caused by detector calibration or lack of artifact reducing image post-processing. Due to a higher dose in terms of mGy/mAs at both head and body FOV, the contrast to noise ratio is higher in the AIRO system than in the Siemens scanner. However detectability of the low contrast objects is poorer in the AIRO due to the presence of ring artifacts in the location of the targets.
Smart Antennas for Wireless CDMA (1999)

From the Publisher:
The text has been created to fuel the growing demand for knowledge in two emerging areas: adaptive antennas (also know as smart antennas) and Code Division Multiple Access. The goal of the bok is to provide fundamental and practical information for practicing engineers, students, and researchers in industry as well as academia. The contents of the book have been shaped by the adoption of the IS-95 J-STD-008 CDMA standard, the new 14,400 bps voice coder for Rate Set 2 channels, new methods and models for implementation and modeling of smart antennas in CDMA, and the stringent wireless E-911 position location requirements imposed by the Federal Communications Commission. With regard to the FCC requirement, material has been added on Direction Finding and Position Location, which are of major concern to service providers due to upcoming regulatory requirements.
Physiology of the tomato mutant alcobaca (1980)

Abstract Alcobaca is commonly regarded as an abnormally ripening mutant of the tomato ( Lycopersicon esculentum Mill.). Alcobaca fruits were found to be similar to cv. Rutgers fruits in the following characteristics: time between full anthesis and the onset of ripening, response to ethephon, flavor, pH and concentrations of titratable acids, total soluble solids and reducing sugars. The pattern of CO 2 and ethylene climacteric are similar in the two plant types, but the peak levels were lower and occurred later in alcobaca than in ‘Rutgers’. The mutant fruits differed from fruits of normal varieties in their greatly prolonged shelf life, their relatively low activity of polygalacturonase (PG) and polymethylgalacturonase (PMG), and their low level of endogenous ethylene. Fruits of the mutant harvested before the onset of ripening failed to reach normal pigmentation and remained yellow. Fruits harvested at the onset of ripening reached an orange color, while fruits ripened while attached to the plant reached almost normal pigmentation. These results suggest that alcobaca is a slow ripening mutant and does not belong to the category of non‐ripening mutants.

DÏoT: A Federated Self-learning Anomaly Detection System for IoT (2019)

IoT devices are increasingly deployed in daily life. Many of these devices are, however, vulnerable due to insecure design, implementation, and configuration. As a result, many networks already have vulnerable IoT devices that are easy to compromise. This has led to a new category of malware specifically targeting IoT devices. However, existing intrusion detection techniques are not effective in detecting compromised IoT devices given the massive scale of the problem in terms of the number of different types of devices and manufacturers involved. In this paper, we present DÏoT, an autonomous self-learning distributed system for detecting compromised IoT devices. DÏoT builds effectively on device-type-specific communication profiles without human intervention nor labeled data that are subsequently used to detect anomalous deviations in devices' communication behavior, potentially caused by malicious adversaries. DÏoT utilizes a federated learning approach for aggregating behavior profiles efficiently. To the best of our knowledge, it is the first system to employ a federated learning approach to anomaly-detection-based intrusion detection. Consequently, DÏoT can cope with emerging new and unknown attacks. We systematically and extensively evaluated more than 30 off-the-shelf IoT devices over a long term and show that DÏoT is highly effective (95.6% detection rate) and fast (257 ms) at detecting devices compromised by, for instance, the infamous Mirai malware. DÏoT reported no false alarms when evaluated in a real-world smart home deployment setting.
Edge flow: A framework of boundary detection and image segmentation (2002)

A novel boundary detection scheme based on "edge flow" is proposed in this paper. This scheme utilizes a predictive coding model to identify the direction of change in color and texture at each image location at a given scale, and constructs an edge flow vector. By iteratively propagating the edge flow, the boundaries can be detected at image locations which encounter two opposite directions of flow in the stable state. A user defined image scale is the only significant control parameter that is needed by the algorithm. The scheme facilitates integration of color and texture into a single framework for boundary detection.
Specific fluorescence determination of lithium ion based on 2-(2-hydroxyphenyl)benzoxazole (2001)

A fluorimetric method for the determination of lithium ion is described in this paper, based on the coordination reaction between 2-(2-hydroxyphenyl)benzoxazole (HPBO) and lithium ion under basic conditions in acetonitrile. The fluorescence intensity is drastically enhanced compared with that of free HPBO upon the addition of lithium ion in the range of 1.0 × 10−7 to 1.0 × 10−4 M, but not for other alkali-metal and alkaline earth metal cations such as Na+, K+, Ca2+ and Mg2+
Xanthomatous Hypophysitis Mimicking a Pituitary Adenoma: Case Report and Review of the Literature (2010)

Background. Hypophysitis is an inflammatory disease of the pituitary gland that may mimic pituitary tumors clinically and radiologically. Case Description. We report a case of a xanthomatous hypophysitis initially diagnosed as pituitary adenoma. A 31-year-old woman presented with headache, diabetes insipidus, and amenorrhea. A head CT scan showed no intrasellar changes, while an MRI scan showed a sellar cystic mass. An endocrinological work up revealed mild hypocortisolism and diabetes insipidus (DI). Transsphenoidal surgery was performed. The intraoperative histological examination suggested a pituitary adenoma. The removed tissue showed central necrosis surrounded by accumulation of foamy cells and xanthomatous epithelioid cells. The patient made an uneventful postoperative recovery, Nevertheless, DI persisted and the adenohypophysis hypofunction did not recover. Conclusion. We describe an unusual inflammatory lesion of the pituitary gland mimicking an adenoma. A high level of clinical suspicion of inflammatory disorders is necessary for correct diagnosis and optimal management.
