VQ-based face recognition algorithm using code pattern classification and Self-Organizing Maps (2008)

In this paper, an improved codebook design method is proposed for VQ-based fast face recognition algorithm to improve recognition accuracy. Combined by a systematically organized codebook based on the classification of code patterns abstracted from facial images and another codebook created by Kohonenpsilas Self-Organizing Maps (SOM) method, an optimized codebook consisted of 2times2 codevectors for facial images is generated. The performance of proposed algorithm is demonstrated by using publicly available AT&T database containing variations in lighting, posing, and expressions. Compared with the algorithms employing original codebook or SOM codebook separately, experimental results show face recognition using proposed codebook is more efficient. The highest average recognition rate of 98.6% is obtained for 40 personspsila 400 images of AT&T database.
Promoter Hypermethylation Profile of Kidney Cancer (2004)

Promoter hypermethylation is common, can occur relatively early, may disrupt critical pathways, and, thus, likely plays an important role in kidney tumorigenesis. A hypermethylation profile may be useful in predicting a patient's clinical outcome and provide molecular markers for diagnostic and prognostic approaches to kidney cancer.
Data and energy cooperation in relay-enhanced OFDM systems (2016)

To advance green communications, we propose an orthogonal frequency division multiplexing (OFDM) based cooperative relay system, where the relay node not only can forward the data to the destination node, but is also capable of transferring energy to the source node. In particular, to maximize the overall system capacity in multiple subchannels and multiple time slots while meeting the power constraints, a power allocation optimization problem is formulated and solved in three steps. First, at each data transmission and data forwarding cycle, we split the total transmission power of relay into two parts, one for data forwarding and the other as power supplement for the source node. Then, our analysis indicates that at each cycle, once all of the subchannels are sorted in a certain order, the relay node will only provide forwarding power to the subchannels with index greater than a certain value. Meanwhile, the incentive for the relay node to provide power supplement should be strong enough such that relay chooses not to simultaneously transmit data and energy. Then, an equivalent convex constrained optimization problem is formulated and the solution is derived by solving the Lagrange function. The solution takes the form of water-filling in combination with a cooperative feature. Numerical results demonstrate that energy cooperation notably improves the system capacity.

Gradering av kvaliteten på dokumentasjonen (2013)

Hva menes med at noe er ”godt dokumentert”? I hvilken grad kan vi stole på forskningsresultater? Den mest brukte metoden for å vurdere kvalitet på dokumentasjon og styrke på anbefalinger er GRADE (Grading of Recommendations Assessment, Development and Evaluation). GRADE brukes i systematiske oversikter og i retningslinjer der man vurderer effekten av og gir anbefalinger om ulike behandlingsalternativer. I GRADE gjøres et klart skille mellom kvaliteten på dokumentasjonen og styrken på anbefalingene. For å vurdere kvaliteten på dokumentasjonen tar GRADE utgangspunkt i en godt utført systematisk oversikt som omfatter den aktuelle problemstillingen. Både randomiserte forsøk og observasjonsstuder kan inngå. GRADE benytter fem kriterier som vurderes for eventuell nedgradering av kvaliteten på dokumentasjonen: studiekvalitet, konsistens mellom studiene, direkthet, presisjon og rapporteringsskjevheter. I tillegg kan observasjonsstudier vurderes for oppgradering ved følgende tre kriterier: sterke assosiasjoner, dose-responseffekter og forvekslingsfaktorer. Alle vurderingene noteres og presenteres sammen med resultatene i oppsummeringstabeller.Vist GE, Sæterdal I, Vandvik PO, Flottorp SA. Grading the quality of the evidence. Nor J Epidemiol 2013; 23 (2): 151-156.ENGLISH SUMMARY What is meant by the claim that something is “well documented”? How much confidence can we have in the results? The most commonly used method to grade the quality of the evidence is GRADE (Grading of Recommendations Assessment, Development and Evaluation). GRADE is used in systematic reviews, where the effects of different treatments or options are being compared, and in guidelines with recommendations about the competing options. GRADE makes a clear distinction between the quality of the evidence and the strength of recommendation. When grading the quality of the evidence with GRADE, the starting point is a well conducted systematic review of research on the question that is being assessed. Both randomized controlled trials and observational studies can be included in the evaluation. GRADE uses five criteria to judge for possible downgrading of the quality of the evidence: risk of bias, consistency, directness, precision and reporting bias. Observational studies may in addition be assessed for possible upgrading of the quality of evidence using the following three criteria: strong association, dose response relationship, and plausible confounding. All the judgments are noted and presented together with the results in tables.

Distributed Resource Management in Downlink Cache-Enabled Multi-Cloud Radio Access Networks (2021)

In light of the premises of beyond fifth generation (B5G) networks, the need for better exploiting the capabilities of cloud-enabled networks arises, so as to cope with the large-scale interference resulting from the massive increase of data-hungry systems. A compound of several clouds, jointly managing inter-cloud and intra-cloud interference, constitutes a practical solution to account for the requirements of B5G networks. This paper considers a multi-cloud radio access network model (MC-RAN), where each cloud is connected to a distinct set of base stations (BSs) via limited capacity fronthaul links. The BSs are equipped with local cache storage and baseband processing capabilities, as a means to alleviate the fronthaul congestion problem. The paper then investigates the problem of jointly assigning users to clouds and determining their beamforming vectors so as to maximize the network-wide energy efficiency (EE) subject to fronthaul capacity and transmit power constraints. This paper solves such a mixed discrete-continuous, non-convex optimization problem using fractional programming (FP) and successive inner-convex approximation (SICA) techniques to deal with the non-convexity of the continuous part of the problem, and $l_0$-norm approximation to account for the binary association part. A highlight of the proposed algorithm is its capability of being implemented in a distributed fashion across the network's multiple clouds through a reasonable amount of information exchange. The numerical simulations illustrate the pronounced role the proposed algorithm plays in alleviating the interference of large-scale MC-RANs, especially in dense networks.
Restoration of lordosis and disk height after single‐level transforaminal lumbar interbody fusion (2012)

Intervertebral height and lumbar lordosis reconstruction are important for achieving good surgical results; guidance regarding the likely changes in lumbar lordosis and disk height after TLIF is provided by our findings.
Optical resonances in periodic surface arrays of metallic patches (2003)

The transmission of light along the surface normal through an air-quartz-glass interface covered with a periodic array of thin, rectangular gold patches has been studied over the visible to infrared range. The various structures that are observed can be qualitatively understood as arising from standing-wave resonances set by the size and surroundings of the metal patches. A method-of-moments calculational scheme provides simulations in good quantitative agreement with the data. It is shown how the standing-wave picture provides a useful conceptual framework to understand and exploit such systems.
Discovery and Preclinical Evaluation of [4-[[1-(3-fluorophenyl)methyl]-1H-indazol-5-ylamino]-5-methylpyrrolo[2,1-f][1,2,4]triazin-6-yl]carbamic Acid, (3S)-3-Morpholinylmethyl Ester (BMS-599626), a Selective and Orally Efficacious Inhibitor of Human Epidermal Growth Factor Receptor 1 and 2 Kinases (2009)

Structure-activity relationships in a series of 4-[1H-indazol-5-ylamino]pyrrolo[2,1-f][1,2,4]triazine-6-carbamates identified dual human epidermal growth factor receptor (HER)1/HER2 kinase inhibitors with excellent biochemical potency and kinase selectivity. On the basis of its favorable pharmacokinetic profile and robust in vivo activity in HER1 and HER2 driven tumor models, 13 (BMS-599626) was selected as a clinical candidate for treatment of solid tumors.
Performance evaluation of ephemeral logging (1993)

Ephemeral logging (EL) is a new technique for managing a log of database activity on disk. It does not require periodic checkpoints and does not abort lengthy transactions as frequently as traditional firewall logging for the same amount of disk space. Therefore, it is well suited for highly concurrent databases and applications which have a wide distribution of transaction lifetimes.This paper briefly explains EL and then analyzes its performance. Simulation studies indicate that it can offer significant savings in disk space, at the expense of slightly higher bandwidth for logging and more main memory. The reduced size of the log implies much faster recovery after a crash as well as cost savings.EL is the method of choice in some but not all situations. We assess the limitations of our current knowledge about EL and suggest promising directions for further research.
Effects of the Selective Cyclooxygenase-2 Inhibitor Analgesic Celecoxib on Renal Carbonic Anhydrase Enzyme Activity: A Randomized, Controlled Trial (2006)

Rofecoxib and celecoxib were the first cyclooxygenase-2 (COX-2)-specific inhibitors to be marketed as effective anti inflammatory agents. The results of several recent trials and a meta analysis of currently available studies all demonstrate a greater incidence of increased blood pressure, edema, and cardiovascular events in subjects treated with rofecoxib compared with celecoxib. As an approach to the assessment of molecular mechanisms that may contribute to these cardiorenal differences, this study investigated the inhibitory effects of celecoxib on renal carbonic anhydrase enzyme activity in human hypertensive subjects because in vitro enzyme studies demonstrate such an effect. Ten subjects with stable, treated hypertension were randomized to 1 of 3 treatment sequences, which included, in differing order, 200 mg celecoxib twice a day, 250 mg acetazolamide twice a day, or placebo twice a day. Whereas acetazolamide caused a bicarbonate diuresis and a hyperchloremic metabolic acidosis, celecoxib appeared to have no detectable effect on renal carbonic anhydrase or acid-base homeostasis. Thus, in this short-term study of human subjects, therapeutic doses of celecoxib did not appear to have a clinically significant inhibitory action on renal carbonic anhydrase.
Homogeneous α-Olefin Polymerizations over Racemic Ethylene-Bridged ansa-Bis(2-(tert-butyldimethylsiloxy)- 1-indenyl) and ansa-Bis(2-(tert-butyldimethylsiloxy)- 4,5,6,7-tetrahydro-1-indenyl) Metallocene Dichlorides (1997)

Ethylene and propylene were polymerized over the siloxy-substituted bis(indenyl) ansa-metallocenes, rac-[ethylenebis(2-(tert-butyldimethylsiloxy)indenyl)]zirconium dichloride (1), rac-[ethylenebis(2-(tert-butyldimethylsiloxy)-4,5,6,7-tetrahydroindenyl)]zirconium dichloride (2), and rac-[ethylenebis(2-(tert-butyldimethylsiloxy)indenyl)]hafnium dichloride (3), using methylaluminoxane (MAO) and trityl tetrakis(pentafluorophenyl)borate as cocatalysts. Especially complex 1 forms a highly active catalyst precursor for the polymerization of α-olefins. Synthesis and characterization of 2 and 3 are described. The 1/MAO and 3/MAO catalyst systems show high polymerization activities at exceptionally low [Al]:[Zr] ratios [(100−250):1]. For both catalysts, extensive chain transfer to aluminum is observed as the predominant chain-transfer mechanism. Preliminary results from copolymerization of ethylene with 1-hexene and 1-hexadecene over 1/MAO indicate a good comonomer response.
Possible cross-feeding pathway of facultative methylotroph Methyloceanibacter caenitepidi Gela4 on methanotroph Methylocaldum marinum S8 (2019)

Non-methanotrophic bacteria such as methylotrophs often coexist with methane-oxidizing bacteria (methanotrophs) by cross-feeding on methane-derived carbon. Methanol has long been considered a major compound that mediates cross-feeding of methane-derived carbon. Despite the potential importance of cross-feeding in the global carbon cycle, only a few studies have actually explored metabolic responses of a bacteria when cross-feeding on a methanotroph. Recently, we isolated a novel facultative methylotroph, Methyloceanibacter caenitepidi Gela4, which grows syntrophically with the methanotroph, Methylocaldum marinum S8. To assess the potential metabolic pathways in M. caenitepidi Gela4 co-cultured with M. marinum S8, we conducted genomic analyses of the two strains, as well as RNA-Seq and chemical analyses of M. caenitepidi Gela4, both in pure culture with methanol and in co-culture with methanotrophs. Genes involved in the serine pathway were downregulated in M. caenitepidi Gela4 under co-culture conditions, and methanol was below the detection limit (< 310 nM) in both pure culture of M. marinum S8 and co-culture. In contrast, genes involved in the tricarboxylic acid cycle, as well as acetyl-CoA synthetase, were upregulated in M. caenitepidi Gela4 under co-culture conditions. Notably, a pure culture of M. marinum S8 produced acetate (< 16 μM) during growth. These results suggested that an organic compound other than methanol, possibly acetate, might be the major carbon source for M. caenitepidi Gela4 cross-fed by M. marinum S8. Co-culture of M. caenitepidi Gela4 and M. marinum S8 may represent a model system to further study methanol-independent cross-feeding from methanotrophs to non-methanotrophic bacteria.

X-Ray Photoemission Investigation of the Beryllium Oxide Band Alignment with Magnesium Oxide and Estimates for Other Insulating and Conducting Oxides (2021)

Beryllium oxide (BeO) is a wurtzite structured, large bandgap ( E g &gt; 8 eV) material of significant interest as an alloying agent and cladding dielectric in various wide band gap oxide based optoelectronic devices. The success of such devices is highly reliant on bandgap and band alignment engineering to achieve sufficient charge carrier and optical confinement for device operation. In this regard, we have utilized x-ray photoemission spectroscopy (XPS) to determine the valence band offset (VBO) between atomic layer deposited (ALD) BeO and a magnesium oxide (MgO) substrate with (001) orientation. The BeO VBO with MgO (001) was determined to be 0.1 ± 0.15 eV. Applying the rules of commutativity and transitivity for band alignment, we additionally predict the BeO VBO with other wide bandgap conductive oxides such as ZnO, Ga 2 O 3 , and InGaZnO 4 , to be 1.15 ± 0.3 eV, 0.3 ± 0.2 eV, and 0.9 ± 0.2 eV, respectively. Utilizing the reported bandgaps for ALD BeO and the conductive oxides, we find a Type I band alignment with CBOs &gt; 1 eV in all cases. BeO is therefore a promising dielectric for oxide based optoelectronic and high-frequency, -power, and -temperature device applications
Optimizing checkpoint inhibitors therapy for relapsed or progressive classic Hodgkin lymphoma by multiplex immunohistochemistry of the tumor microenvironment (2019)

Immune checkpoint-blocking antibodies have therapeutic activity against relapsed or progressive classic Hodgkin lymphoma (cHL), but Hodgkin Reed-Sternberg cells can develop resistance to this therapy via multiple mechanisms. To improve the efficacy of immune checkpoint blockade, we need a more precise understanding of the immune escape mechanisms active in individual cHL patients, and this requires a detailed characterization of immune cell populations in the tumor microenvironment. These cell-cell interactions can now be studied by multiplex immunohistochemistry coupled to digital image analysis. This method should allow the identification of actionable target molecules mediating resistance to immune checkpoint inhibitors in individual cHL patients, thereby favoring the implementation of personalized therapies.
<title>Use of filter vectors in hyperspectral data analysis</title> (1995)

We report recent progress using a filter vector technique to analyze the data from a hyperspectral image. The filter vector technique finds the optimal filter vectors for demixing the complex patterns found in the hyperspectral image. The method has the potential to be implemented in real time since it is fully parallel. Computation of the filter vectors for a given family of known species vectors is fast and direct and improved algorithms for developing of the algorithm which may be updated as conditions change is possible. Advantages of using the filter vector techniques over the technique of pattern matching will be discussed. The portable hyperspectral images for low light spectroscopy (PHILLS) instrument has been used on a number of depolyments in the last year. Typically, the instrument files on the Naval Research Laboratory's P-3 Orion aircraft. Currently, the PHILLS instrument records over 1000 wavelength bands between UV and near IR. Results from a number of deployment and test situations is shown.
