This Letter presents a compressive camera that integrates mechanical translation and spectral dispersion to compress a multi-spectral, high-speed scene onto a monochrome, video-rate detector. Experimental reconstructions of 17 spectral channels and 11 temporal channels from a single measurement are reported for a megapixel-scale monochrome camera.
α-Inhibin Gene Expression Occurs in the Ovine Adrenal Cortex, and is Regulated by Adrenocorticotropin (1987)

Inhibin is a glycoprotein hormone composed of two nonidentical subunits. It is produced by the ovary and testis and plays a vital role in gonadal function by inhibiting the secretion of FSH. More recently, additional activities associated with inhibin peptides have been identified. Inhibin heterodimers (alpha-beta) are reported to act directly on ovarian granulosa cells and inhibit estrogen production induced by FSH. Furthermore, homodimers of beta-inhibin subunits stimulate the secretion of FSH, an activity that is directly opposite to that of inhibin. Each of these inhibin-related activities are concerned with the hypothalamic-pituitary-gonadal axis. We have investigated further the complexity of inhibin activity by determining whether inhibin genes are expressed in nongonadal tissue. RNA hybridization experiments demonstrate that the alpha-inhibin gene is expressed in the sheep adrenal cortex and hybridization histochemistry shows that this gene is expressed in each of the functional zones within the cortex. Dot blot analysis showed that the level of alpha mRNA within the adrenal is influenced by ACTH, one of the major regulators of adrenal cortex function. These observations imply that there are inhibin-related peptides not directly associated with the gonads. beta-inhibin gene expression was not clearly detected in the adrenal and we conclude that if expression occurs then it does so at extremely low levels.
Expression and regulation of metallothionein mRNA levels in the prostates of Noble rats: Lack of expression in the ventral prostate and regulation by sex hormones in the dorsolateral prostate (1996)

The rat prostate is composed of two anatomically well-defined regions designated as the ventral prostate (VP) and the dorsolateral prostate (DLP). VP and DLP are known to exhibit marked cytological, biochemical, and functional differences including differential susceptibilities to carcinogens. While the VP is uniquely susceptible to cadmium carcinogenicity [1,2], the DLP is sensitive to sex hormone-induced cancer [3,4]. The role played by the heavy metal binding protein, metallothionein (MT), in the prostate is largely unknown. It is still controversial as to whether MT is expressed in the rat gland. The aim of the present study is to examine the expression pattern of MT mRNA in the rat gland and its probable regulation by heavy metal ions and sex hormones, in order to gain insight into the biological function of MT in the prostate. Northern hybridization and reverse transcriptase-polymerase chain reaction analyses revealed constitutive expression of MT mRNA in the DLP and a lack of expression of the transcript in the VP. In situ hybridization localized the transcript to the epithelium of the DLP, with the lateral prostate epithelium exhibiting the highest level of expression. Administration of cadmium and zinc failed to induce MT transcription in the VP, nor were these treatments effective in elevating levels of MT mRNA in the DLP. A 60% reduction in MT message levels was observed in the DLP following orchiectomy. MT transcript levels in the DLPs of castrates were restored by readministration of androgen to the animals. Long-term treatments (16 weeks) of rats with estradiol-17 beta (E2) or testosterone (T) plus E2 induced a 2.8-fold and a 5-fold increase in MT message content in the DLP, respectively. In sum, MT mRNA was shown to be absent in the VP and was not inducible by heavy metal ions or hormones in this prostatic lobe. These findings substantiate the belief that MT plays a role in heavy metal detoxification and deficiency in its expression may contribute to the unique susceptibility of the VP to cadmium carcinogenicity. By contrast, constitutive expression of MT was demonstrated in the DLP, which was shown to be regulated by androgen and not by exogenously administered heavy metal ions. These results suggest a participatory role of MT in the normal functioning of the DLP. The fact that high levels of MT mRNA were induced in the DLP following long-term estrogenic or conjoint androgenic-estrogenic action alludes to the possibility that MT may serve as an intracellular antioxidant in DLP cells.
Quantitative Analysis of Hydroperoxyl Radical Using Flow Injection Analysis with Chemiluminescence Detection (2003)

The hydroperoxyl radical (HO2) is one of the most abundant free radicals in the atmosphere, where it participates in a series of photochemical reactions that determine the fate of natural and anthropogenic emissions. In addition, HO2 is found in droplets and surface water as a result of photochemical formation and gas-phase scavenging. We describe a quantitative method for determining trace concentrations of HO2 radicals that exploits the chemiluminescence produced upon reaction with a synthetic analogue of luciferin from the crustacean Cypridina. The technique is linear at least up to 1 microM HO2(aq) and has a minimum detection limit of 0.1 nM. A unique feature of this analysis is a calibration method using stable aqueous HO2 standards produced in submicromolar concentrations using 60Co gamma-radiolysis. The advantage of this method in comparison to others in consideration of field deployment is its simplicity, low cost, and minimal size and power requirements. One intended application of this technique is the measurement of atmospheric HO2 radicals following collection into aqueous solution.
Semantic indexing of multimedia documents (2002)

We propose two approaches for semantic indexing of audio-visual documents, based on bottom-up and top-down strategies. We base the first approach on a finite-state machine using low-level motion indices extracted from an MPEG compressed bitstream. The second approach innovatively performs semantic indexing through Hidden Markov Models.
Study on the prevention of SYN flooding by using traffic policing (2002)

In this paper, the usage parameter control (UPC) mechanisms, adopted in asynchronous transfer mode (ATM) networks, are applied to prevent the network server from SYN flooding attack. The basic idea of the proposed scheme is to consider the server being congested during SYN flooding attack, and the UPC is used as a traffic control mechanism to regulate a great number of arrival SYN packets so that the server can be prevented from denial of services (DoS). Both the sliding window and leaky bucket mechanisms are studied to examine the defense effectiveness. Parameters of the sliding window and leaky bucket are determined according to the abort time, buffer status of the server, and the predicted packet arrival rate. This method provides an alternative concept on security management of network servers. The experimental results also show that the proposed method can effectively prevent the server from SYN flooding attack.
A Distributed Policy Based Solution in a Fault Management Scenario (2006)

The Madeira project, part of the Celtic Initiative 1 , investigates the use of a fully distributed, policy-based network management framework that exploits the peer-to-peer paradigm with the aim of providing a successful solution to Next Generation Networks (NGN) challenges. This paper is focused on the distributed policy-based approach adopted in the project. Thanks to this approach, the management system is flexible and adaptable to different management applications of networks with time-varying topologies. Currently available results coming from the execution of specific scenarios in the area of Fault Management reveal that the policy-based system architecture works properly in the highly distributed peer-to-peer environment where it is deployed.

Association between surgical volume and clinical outcomes following coronary artery bypass grafting in contemporary practice (2019)

In contemporary practice, in which one-third of CABG-capable hospitals perform < 100 CABG operations annually, a strong relationship is observed between surgical volume and adjusted in-hospital morbidity, mortality, cost, and 30-day readmission.
Effect of a Medical Device containing Xyloglucan and Pea Protein on a Murine Model of Atopical Dermatitis. (2020)

Atopic dermatitis (AD) is a chronic inflammatory disease of the skin, characterized by intense itching and dry skin. The etiology of AD is complex and has not been fully clarified, involving genetic susceptibility, immunological dysfunction, epidermal barrier and environmental factors. Xyloglucan (XG) and pea protein (PP) are two compounds of natural origin characterized respectively by a physical barrier creation that protects mucosal tissues reducing inflammation. The aim of the present study was to evaluate the potential beneficial effects of XG + PP in a mouse models of AD and S. aureus infection‐ associated AD. Mice were topically treated with 200 μl of 0.5% oxazolone on the dorsal skin three times a week for AD induction. Mice received XG and PP by topical administration, 1 hour before oxazolone treatment. In experiment of S. aureus infection‐ associated AD, to induce superficial superinfection of the skin, mice were also treated with 5 μl of 10 8 of a culture of S. aureus for 2 weeks; mice superinfected received XG and PP by topical administration 1 hour before oxazolone + S. aureus . Following 4 weeks, the skin was removed for histological and biochemical analysis. Our results clearly demonstrated the protective barrier effect of XG and PP characterized by a reduction in histological tissue changes induced‐AD, mastocyte degranulation and tight junction permeability in the skin following oxazolone treatment. Moreover, XG+PP was able to reduce filaggrin expression, a hallmark of AD. Our data also support the effectiveness of XG+PP to reduce the damage by superinfection post AD induced by s. aureus . In conclusion, the medical device containing XG and PP could be considered an ideal approach for the treatment of AD.
An Investigation of the Micro-Electrical Discharge Machining of Nickel-Titanium Shape Memory Alloy Using Grey Relations Coupled with Principal Component Analysis (2017)

Shape memory alloys (SMAs) are advanced engineering materials which possess shape memory effects and super-elastic properties. Their high strength, high wear-resistance, pseudo plasticity, etc., makes the machining of Ni-Ti based SMAs difficult using traditional techniques. Among all non-conventional processes, micro-electric discharge machining (micro-EDM) is considered one of the leading processes for micro-machining, owing to its high aspect ratio and capability to machine hard-to-cut materials with good surface finish.The selection of the most appropriate input parameter combination to provide the optimum values for various responses is very important in micro-EDM. This article demonstrates the methodology for optimizing multiple quality characteristics (overcut, taper angle and surface roughness) to enhance the quality of micro-holes in Ni-Ti based alloy, using the Grey–Taguchi method. A Taguchi-based grey relational analysis coupled with principal component analysis (Grey-PCA) methodology was implemented to investigate the effect of three important micro-EDM process parameters, namely capacitance, voltage and electrode material.The analysis of the individual responses established the importance of multi-response optimization. The main effects plots for the micro-EDM parameters and Analysis of Variance (ANOVA) indicate that every parameter does not produce same effect on individual responses, and also that the percent contribution of each parameter to individual response is highly varied. As a result, multi-response optimization was implemented using Grey-PCA. Further, this study revealed that the electrode material had the strongest effect on the multi-response parameter, followed by the voltage and capacitance. The main effects plot for the Grey-PCA shows that the micro-EDM parameters “capacitance” at level-2 (i.e., 475 pF), “discharge voltage” at level-1 (i.e., 80 V) and the “electrode material” Cu provided the best multi-response.
Robust classification of rare queries using web knowledge (2007)

We propose a methodology for building a practical robust query classification system that can identify thousands of query classes with reasonable accuracy, while dealing in real-time with the query volume of a commercial web search engine. We use a blind feedback technique: given a query, we determine its topic by classifying the web search results retrieved by the query. Motivated by the needs of search advertising, we primarily focus on rare queries, which are the hardest from the point of view of machine learning, yet in aggregation account for a considerable fraction of search engine traffic. Empirical evaluation confirms that our methodology yields a considerably higher classification accuracy than previously reported. We believe that the proposed methodology will lead to better matching of online ads to rare queries and overall to a better user experience.

Genes for CS2 pili of enterotoxigenic Escherichia coli and their interchangeability with those for CS1 pili (1995)

We have cloned and sequenced the DNA needed for production of CS2 pili in Escherichia coli K-12. The four open reading frames, cotB, cotA, cotC, and cotD, show homology with the genes needed for production of CS1 and CFA/I pili, which are also found on enterotoxigenic E. coli associated with human diarrheal disease. We also report that CotA plus CotB interact with the CS1 gene products CooC and CooD to form pili that can be visualized by electron microscopy and, conversely, that the CS1 gene products CooA and CooB interact with CotC and CotD to form pili.
ESAT-6 and CFP-10 can be combined to reduce the cost of testing for Mycobacterium tuberculosis infection, but CFP-10 responses associate with active disease (2007)

Commercial tests measuring IFN-gamma responses to ESAT-6 and CFP-10 are available for diagnosing Mycobacterium tuberculosis infection. Measures that minimize cost and complexity will facilitate their application in less-developed countries. We investigated whether overlapping peptides representing both ESAT-6 and CFP-10 are required to detect M. tuberculosis infection in a high TB-burden country, and whether they can be combined in a single pool. ESAT-6 and CFP-10 peptides were compared in IFN-gamma enzyme-linked immunospot (ELISPOT) in 183 HIV-negative smear-positive TB cases and 1673 HIV-negative household contacts. Separate peptide pools for each antigen were compared with a combined pool in 498 contacts. Forty per cent of responsive contacts recognized both antigens, 51% only ESAT-6 and 10% only CFP-10, whereas 56% of responsive cases recognized both antigens, 30% only ESAT-6 and 13% only CFP-10. Accordingly, CFP-10 response rates were higher for TB cases (odds ratio 2.409, P<0.001). Low purified protein derivative response rates indicated that responses to CFP-10 only were non-specific in contacts. Agreement between peptides in separate versus combined pools was good (kappa=0.758, r=0.840). Therefore a combined ESAT-6/CFP-10 peptide pool provided maximum sensitivity and efficiency, but CFP-10 was mainly required to detect active disease.
Influence of a nanometer-scale surface enhancement on de novo bone formation on titanium implants: a histomorphometric study in human maxillae. (2007)

In this prospective randomized controlled clinical study, small titanium implants were placed in posterior maxillae for the purpose of assessing the rate and extent of new bone development. Nine pairs of site evaluation implants were placed in posterior areas of maxillae and retrieved with trephine drills after 4 or 8 weeks of unloaded healing. The amount of bone in linear contact (%) with the implant surface was used to determine the osteoconductive potential of the implant surface. Implant surfaces were dual acid etched (n = 9) (controls) or dual acid etched and further conditioned with nanometer-scale crystals of calcium phosphate (n = 9) (test implants), and the surfaces were compared. The implants and surrounding tissues were processed for histologic analysis. The mean bone-to-implant contact value for the test surface was significantly increased over that of the control implants at both time intervals (P <.01). For the implants/patients included in this study, the addition of a nanometer-scale calcium phosphate treatment to a dual acid-etched implant surface appeared to increase the extent of bone development after 4 and 8 weeks of healing.
Fabrication and evaluation of highly manufacturable nanoscale flow-through parallel electrode structures (2004)

A unique nanoscale gap configuration having parallel-plate electrodes and an integrated flow structure was designed, developed, and fabricated using micro- and nanomachining techniques. This structure is highly manufacturable and shows an excellent fabrication yield (more than 90%). Applications data are presented for 30 and 50nm gap spacing structures used to monitor the formation of a 6-mercapto-1-hexanol self-assembled monolayer on the device electrode surfaces. The structure was found to be very robust in a high, inter-electrode electric-field environment (∼6×106V∕cm in air).
Influence of dietary carnitine and/or chromium on blood parameters of gestating sows (2002)

Gestating sows (n=44; parity=2.0; BW=458 lb) were used to determine the effects of dietary Carnitine and/or chromium picolinate on daily blood parameter profiles. Diets were formulated as a 2 Ã— 2 factorial with carnitine (0 or 50 ppm) and chromium (0 or 200 ppb) and were fed from breeding, through gestation, lactation, and 30 d into the next gestation at which time blood was collected. Sows were fed one meal per day during gestation (2.1 kg) and ad libitum during lactation. Sows were fitted with indwelling venous catheters and blood (plasma) was collected at feeding, once every 15 min for the first 3 h after feeding, and at 6, 9, 15, 20, and 24 h after feeding. Chromium picolinate elicited its greatest effect immediately after feeding (0-3 h) by decreasing (P<0.05) insulin and cpeptide, whereas Carnitine decreased (P<0.05) NEFA and urea N (PUN) in the fasting state (6-24 h post-feeding). Sows fed both carnitine and chromium exhibited intermediate responses. Post-feeding glucose peak was lower (P<0.05) for diets with carnitine and/or chromium versus the control and mean glucose concentration was lower (P<0.01) for sows fed diets with chromium. Mean insulin and cpeptide concentration was lowest (P<0.01) for sows fed the diet with chromium and highest for sows fed the control, with sows fed diets with carnitine or carnitine and chromium having intermediate responses (Carnitine Ã— chromium, P<0.01). Mean NEFA was lower (P<0.01) for sows fed diets with carnitine. Mean NEFA and glycerol were higher (P<0.03) for sows fed the diets with chromium. Sows fed the diet with only carnitine had the lowest PUN, but no differences were observed between the other three diets (carnitine Ã— chromium, P<0.01). Dietary carnitine increased (P<0.05) the circulating leptin concentration, specifically in the fasting portion of the day. Both carnitine and chromium were observed to influence (P<0.05) the concentrations of some amino acids. No differences were observed for IGF-1, IGFBP-3, glucagon, or triglyceride (P>0.10); however, sows fed carnitine had numerically higher (P=0.11) IGF-1 and IGFBP-3 (P=0.06). In summary, the changes in metabolites and metabolic hormones indicate that both carnitine and chromium influence energy metabolism of gestating sows; however, their effects on blood parameters are different. Thus, the improvement in energy status from adding both carnitine and chromium may have an additive effect on reproductive performance of sows.; Swine Day, Manhattan, KS, November 14, 2002
