Optimal partition of QoS requirements on unicast paths and multicast trees (2002)

We investigate the problem of optimal resource allocation for end-to-end QoS requirements on unicast paths and multicast trees. Specifically, we consider a framework in which resource allocation is based on local QoS requirements at each network link, and associated with each link is a cost function that increases with the severity of the QoS requirement. Accordingly, the problem that we address is how to partition an end-to-end QoS requirement into local requirements, such that the overall cost is minimized. We establish efficient (polynomial) solutions for both unicast and multicast connections. These results provide the required foundations for the corresponding QoS routing schemes, which identify either paths or trees that lead to minimal overall cost. In addition, we show that our framework provides better tools for coping with other fundamental multicast problems, such as dynamic tree maintenance.
Decreased expression of the long non-coding RNA SLC7A11-AS1 predicts poor prognosis and promotes tumor growth in gastric cancer (2017)

Many lncRNA and mRNA sense-antisense transcripts have been systematically identified in malignant cells. However, the molecular mechanisms of most lncRNA-mRNA pairs in gastric cancer remain largely unknown. We found the gastric cancer-associated lncRNA SLC7A11-AS1 and coding transcript mRNA SLC7A11 in human gastric cancer specimens by microarray. SLC7A11-AS1, antisense to SLC7A11, is significantly down-regulated in gastric cancer and could promote tumor growth <i>in vitro</i> and <i>in vivo</i>. The effects of SLC7A11-AS1 depend on the regulation of SLC7A11 via the ASK1-p38<sup>MAPK</sup>/JNK signaling pathway. These findings suggest that decreased expression of SLC7A11-AS1 contributes to the progression of gastric cancer and may be a novel diagnostic biomarker and effective therapeutic target in gastric cancer patients.
Coffee consumption and cardiometabolic health in UK adults: cross-sectional analysis of the National Diet and Nutrition Survey (2017)

Extensive research has been conducted to examine the relationship between coffee consumption and a wide range of chronic diseases (1) . Links between coffee consumption and cardiometabolic health have been widely reported in the literature but with equivocal results (2)(3)(4) . The present analysis explored coffee consumption in UK adults and examined associations with markers of cardiometabolic health.
Cytochrome c Oxidase Activity in Human Liver Specimens (1990)

Cytochrome c oxidase activity, measured as Vmax (nanomoles of cytochrome c oxidized per second per milligram of protein) and Michaelis constant (Km) (micromoles per liter), was measured spectrophotometrically in human liver specimens obtained by needle biopsy from 43 patients. In 16 normal livers, the Vmax and Km values ranged from 1.26 to 2.25 nmol/s per milligram of protein and from 2.78 to 3.95 mumol/L, respectively. In 27 patients with liver cirrhosis or chronic hepatitis, these values ranged from 1.60 to 3.80 nmol/s per milligram of protein and from 2.80 to 6.50 mumol/L, respectively. Patients with Vmax above 2.5 nmol/s per milligram of protein or Km above 5.0 mumol/L had a high incidence of postoperative complications even after minor hepatic resection. By contrast, even patients with liver cirrhosis or chronic hepatitis could tolerate major hepatic resection as long as their Vmax and Km values were within the normal range. These findings indicate that the cytochrome c oxidase activity in liver specimens can serve as a prognostic sign in hepatic resection even in patients with liver cirrhosis or chronic hepatitis.
Parsimony of Hemodynamic Monitoring Data Sufficient for the Detection of Hemorrhage (2020)

Increasing hemodynamic monitoring featurization by increasing sampling frequency and referencing to personal baseline markedly improves the ability of invasive monitoring to detect bleed.
An Algorithm for Fast Recovery of Sparse Causal Graphs (1991)

Previous asymptotically correct algorithms for recovering causal structure from sample probabilities have been limited even in sparse causal graphs to a few variables. We describe an asymptotically correct algorithm whose complexity for fixed graph connectivity increases polynomially in the number of vertices, and may in practice recover sparse graphs with several hundred variables. From sample data with n = 20,000, an implementation of the algorithm on a DECStation 3100 recovers the edges in a linear version of the ALARM network with 37 vertices and 46 edges. Fewer than 8% of the undirected edges are incorrectly identified in the output. Without prior ordering information, the program also determines the direction of edges for the ALARM graph with an error rate of 14%. Processing time is less than 10 seconds.

Differential Effect of Four-Week Feeding of Different Dietary Fats on the Accumulation of Fat and the Cholesterol and Triglyceride Contents in the Different Fat Depots (2020)

The aim of the present study was to determine the effects of feeding of a high-fat diet containing different types of lipids for four weeks on the cholesterol and triglyceride contents of different fat depots and on body temperature in rats. Four groups of adult rats were fed 10% fat, containing either beef tallow, safflower oil, or fish oil, respectively, as well as a normal rodent diet with 4% fat, for four weeks. The rats on normal rodent diet consumed significantly more food and water than the rats in the other three groups. Rectal temperature increased only after four-week feeding with safflower oil fat. Increased fat deposition and adipocyte size were observed in rats fed safflower oil and beef tallow. In all fat pads of safflower oil-fed rats, cholesterol content was significantly higher than the other three groups. Feeding of beef tallow increased triglyceride depot without increasing cholesterol content. The rats fed fish oil had significantly less triglyceride and cholesterol deposition in adipose tissues than the rats fed safflower oil or beef tallow. These results clearly demonstrated the differences in fat deposition, adipocyte size and number, triglyceride and cholesterol accumulation in fat cells are dependent on the dietary lipid composition.
Prolonged Glucose Normalization of Streptozotocin-Induced Diabetic Mice by Transplantation of Rat Islets Coencapsulated with Crosslinked Hemoglobin (2004)

The present study revealed that the incorporation of Hb-C in islet microcapsules promotes graft function for a longer period of time than the conventional islet capsules. Therefore, Hb-C coencapsulation is a potential approach for prolonging graft function of islet microcapsules and reducing the number of islets required for normoglycemia.
Variable-rate CELP based on subband flatness (1997)

Code-excited linear prediction (CELP) is the predominant methodology for communications quality speech coding below 8 kbps, and several variable-rate CELP schemes have been discussed in the literature, including QCELP, the variable-rate wideband digital cellular mobile radio speech coding standard specified in IS-95. A key component of these speech coders is the detection and classification of speech activity, and several cues for rate variation have been studied, such as measuring the short-term speech energy, deciding whether the speech is voiced or unvoiced, or making more sophisticated phonetic classifications. We present a new method for rate variation based on a measure of subband spectral flatness, called spectral entropy. Spectral entropy is a normalized indicator of the texture of the input spectrum and is thus less dependent on speech and background noise energy variations. We present some results on the use of spectral entropy for voice activity detection across subbands and then evaluate using spectral entropy for deriving mode and rate allocation cues for a variable-rate CELP coder operating at an average rate of 2 kbps. To achieve communications quality speech at this rate, we develop a new split-band vector quantization (VQ) technique for representing the line spectral pairs and a multiple codebook approach for efficiently quantizing the coefficients of a three-tap pitch predictor, called lag-indexed VQ.

Plasma 24S-hydroxycholesterol (cerebrosterol) is increased in Alzheimer and vascular demented patients (2000)

Alzheimer's disease (AD) is characterized by the presence of senile plaques, neurofibrillary tangles, and neuronal cell loss associated with membrane cholesterol release. 24S-hydroxycholesterol (24S-OH-Chol) is an enzymatically oxidized product of cholesterol mainly synthesized in the brain. We tested the hypothesis that plasma levels of this oxysterol could be used as a putative biochemical marker for an altered cholesterol homeostasis in the brain of AD patients. Thirty patients with clinical criteria for AD, 30 healthy volunteers, 18 depressed patients, and 12 patients with vascular dementia (non-Alzheimer demented) were studied. Plasma concentrations of 24S-OH-Chol were assayed by isotope dilution;-mass spectrometry, cholesterol was measured enzymatically, and apolipoprotein E (apoE) was genotyped by polymerase chain reaction and restricted fragment length polymorphism. The concentration of 24S-OH-Chol in AD and non-Alzheimer demented patients was modestly but significantly higher than in healthy controls and in depressed patients. There was no significant difference in the concentrations of 24S-OH-Chol between depressed patients and healthy controls nor between AD and non-Alzheimer demented patients. The apoE straightepsilon4 allele influences plasma 24S-OH-Chol. However, this influence could be completely accounted for by the elevated plasma cholesterol in apoE4 hetero- or homozygotes. Plasma 24S-OH-Chol levels correlated negatively with the severity of dementia. AD and vascular demented patients appear to have higher circulating levels of 24S-OH-Chol than depressed patients and healthy controls. We speculate that 24S-OH-Chol plasma levels may potentially be used as an early biochemical marker for an altered cholesterol homeostasis in the central nervous system. 24S-hydroxycholesterol (cerebrosterol) is increased in Alzheimer and vascular demented patients.
Partial Recuperative Dual Fluid Gas Turbine System (2001)

A new gas turbine cycle was proposed as a method for further improvement of thermal efficiency of a steam injection gas turbine. This cycle has an exhaust heat recovery process which preheats a part of the compressor discharge air and generates steam for injection. In this paper are reported the results of parametric performance analysis of the new cycle gas turbine, and comparisons of thermal efficiency between the new gas turbine cycle and conventional steam injection gas turbine systems. The results of the analysis show that the new cycle gas turbine can realize higher efficiency than the three conventional systems, in the usual pressure ratio range as that applied in actual gas turbines. The effect of the injection steam pressure on thermal efficiency of the new cycle gas turbine is also evaluated.
Resolving Created, Propped, and Effective Hydraulic Fracture Length (2008)

Recent advances in hydraulic fracture mapping technologies have provided a wealth of information on the created fracture&lt;br&gt;length in numerous geologic settings. Prior to such measurements, fracture length was estimated using "un-calibrated" fracture&lt;br&gt;propagation models––but there was significant uncertainty in the results that cascaded into subsequent production analyses.&lt;br&gt;However, we also need to understand how the created fracture length relates to the location of proppant in the fracture and the&lt;br&gt;producing or effective length to evaluate well performance and improve stimulation designs. Unfortunately, the advanced&lt;br&gt;fracture mapping technologies that today provide accurate measurements of the created fracture length cannot provide any&lt;br&gt;insights (yet) into the propped and effective fracture lengths. Advanced production data analyses, pressure transient testing,&lt;br&gt;and/or numerical reservoir modeling are required to determine the effective fracture length.
Recognizing temporal trajectories using the condensation algorithm (2002)

The recognition of human gestures in image sequences is an important and challenging problem that enables a host of human-computer interaction applications. This paper describes an incremental recognition strategy that is an extension of the "Condensation" algorithm proposed by Isard and Blake (1996). Gestures are modeled as temporal trajectories of some estimated parameter over time (in this case velocity). The condensation algorithm is used to incrementally match the gesture models to the input data. The method is demonstrated with an example of an augmented office white-board in which a user makes simple hand gestures to grab regions of the board, print them, save them, etc.
Clinical significance of CDC25A and CDC25B expression in squamous cell carcinomas of the oesophagus (2001)

CDC25A, CDC25B and CDC25C belong to a family of protein phosphatases which activate the cyclin-dependent kinase at different points of the cell cycle. According to accumulating evidence, CDC25A and CDC25B seem to possess oncogenic properties. We have analysed these expressions by immunohistochemistry, western blot and RT-PCR in a series of 100 patients with squamous cell carcinoma of the oesophagus. When compared with non-cancerous cells, CDC25A and CDC25B were strongly expressed in the cytoplasm of cancer cells, with positive (+) classification in 46% (46 cases) and 48% (48 cases), respectively. There was no significant correlation between CDC25A and CDC25B expression, nor was there any association with the expression of other cell cycle-regulating molecules, including cyclin D1, Rb, p16(INK4), p27(KIP1)and PCNA (proliferating cell nuclear antigen). CDC25A (+), as well as CDC25B (+), was more frequently found in patients with deeper tumour invasion and lymph node metastasis, while tumour size was correlated only with CDC25A expression. Postoperative survival was significantly poorer for CDC25A (+) patients than CDC25A (-) patients, but was not affected by the CDC25B status. Nuclear localization of CDC25A was observed in 51 cases (51%), regardless of its cytoplasmic expression, and was not associated with clinico-pathological factors or prognosis. Multivariate analysis revealed only the CDC25A status to be an independent significant prognostic factor among these biological and clinico-pathological factors. CDC25A but not CDC25B may be a new prognostic factor for squamous cell carcinoma of the oesophagus. Thus, regulation of the G1 checkpoint in the cell cycle may be important in oesophageal carcinogenesis, which may also involve many other oncogenes.

Electric field sensors using nonlinear optical polymers (1989)

This work is part of a continuing project that is investigating the use of integrated optical (IO) waveguides and optical fibers coated with nonlinear optical (NLO) polymers as electric field sensing devices. The IO waveguides were fabricated using three different techniques: (1) in the NLO polymer itself (on glass and silicon substrates), (2) in glass microscope slides using thin film silver diffusion and silver ion exchange methods, and (3) in thin film optical epoxies. The Ag + glass and UV cured optical epoxy waveguides were subsequently coated with NLO polymers; the 3-D patterned waveguides provided lateral confinement of the optical wave that propagated in the polymer. A low index buffer layer of polysiloxane glass resin (Owens Illinois GR650E) was needed on the silicon substrates to decrease the propagation loss. The NLO polymers were dip coated or spun on these substrates and were poled with a corona poling technique with fields of the order of 3 MV/cm. Interferometric and polarization rotation methods were used to measure the effects of applied electric fields on the NLO devices at wavelengths of 633, 780, and 830 nm. Electrooptic coefficients were determined and compared with similar coefficients obtained using second harmonic generation methods on the same NLO polymers.

γ-ray decay from neutron-bound and unbound states inMo95and a novel technique for spin determination (2016)

The emission of $\ensuremath{\gamma}$ rays from neutron-bound and neutron-unbound states in $^{95}\mathrm{Mo}$, populated in the $^{94}\mathrm{Mo}(d,p)$ reaction, has been investigated. Charged particles and $\ensuremath{\gamma}$ radiation were detected with arrays of annular silicon and Clover-type high-purity Germanium detectors, respectively. Utilizing $p\ensuremath{-}\ensuremath{\gamma}$ and $p\ensuremath{-}\ensuremath{\gamma}\ensuremath{-}\ensuremath{\gamma}$ coincidences, the $^{95}\mathrm{Mo}$ level scheme was greatly enhanced with 102 new transitions and 43 new states. It agrees well with shell model calculations for excitation energies below $\ensuremath{\approx}2$ MeV. From $p\ensuremath{-}\ensuremath{\gamma}$ coincidence data, a new method for the determination of spins of discrete levels is proposed. The method exploits the suppression of high-angular momentum neutron emission from levels with high spins populated in the $(d,p)$ reaction above the neutron separation energy. Spins for almost all $^{95}\mathrm{Mo}$ levels below 2 MeV (and for a few levels above) have been determined with this method.
Ultra-wide bandwidth with enhanced microwave absorption of electroless Ni–P coated tetrapod-shaped ZnO nano- and microstructures (2015)

A viable lightweight absorber is the current need for stealth technology as well as microwave absorption. Several microwave absorbers have been developed, but it is still a challenge to fabricate an absorber that facilitates microwave absorption in broad bandwidth or covers the maximum portion of the frequency range 2-18 GHz, the commonly used range for radar and other applications. Therefore, it is highly required to develop a wide bandwidth absorber that can provide microwave absorption in the most part of the frequency range 2-18 GHz while simultaneously being lightweight and can be fabricated in desired bulk quantities by the cost-effective synthesis methods. In this paper, an attempt has been made to design an ultra-wide bandwidth absorber with enhanced microwave absorption response by using nickel-phosphorus coated tetrapod-shaped ZnO (Ni-P coated T-ZnO). In the Ni-P coated T-ZnO absorber, ZnO acts as a good dielectric contributor, while Ni as a magnetic constituent to obtain a microwave absorbing composite material, which has favorable absorption properties. Ni-P coated ZnO nano-microstructures are synthesized by a simple and scalable two-step process. First, tetrapod-shaped ZnO (T-ZnO) structures have been grown by the flame transport synthesis (FTS) approach in a single step process and then they have been coated with Ni-P by an electroless coating technique. Their morphology, degree of crystallinity and existing phases were studied in detail by scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray diffraction (XRD) techniques. The complex permittivity and permeability of the "as-fabricated" T-ZnO and Ni-P coated T-ZnO have been measured in the frequency range of 4-14 GHz and their microwave absorption properties are computed using the coaxial transmission-reflection method. The strongest reflection loss (RL) peak value of -36.41 dB has been obtained at a frequency of ∼8.99 GHz with coating thickness of 3.4 mm for the Ni-P coated T-ZnO sample with a broad bandwidth of 10.0 GHz (RL < -10 dB) in the frequency range of 4.0-14.0 GHz.
