Modeling energy consumption in single-hop IEEE 802.11 ad hoc networks (2004)

This paper presents an analytical model to predict energy consumption in saturated IEEE 802.11 single-hop ad hoc networks under ideal channel conditions. The model we introduce takes into account the different operational modes of the IEEE 802.11 DCF MAC, and is validated against packet-level simulations. In contrast to previous works that attempted to characterize the energy consumption of IEEE 802.11 cards in isolated, contention-free channels (i.e., single sender/receiver pair), this paper investigates the extreme opposite case, i.e., when nodes need to contend for channel access under saturation conditions. In such scenarios, our main findings include: (1) contrary to what most previous results indicate, the radio's transmit mode has marginal impact on overall energy consumption, while other modes (receive, idle, etc.) are responsible for most of the energy consumed; (2) the energy cost to transmit useful data increases almost linearly with the network size; and (3) transmitting large payloads is more energy efficient under saturation conditions

Visualizing the appearance and disappearance of the attractor of differentiation using Raman spectral imaging (2015)

Using Raman spectral imaging, we visualized the cell state transition during differentiation and constructed hypothetical potential landscapes for attractors of cellular states on a state space composed of parameters related to the shape of the Raman spectra. As models of differentiation, we used the myogenic C2C12 cell line and mouse embryonic stem cells. Raman spectral imaging can validate the amounts and locations of multiple cellular components that describe the cell state such as proteins, nucleic acids, and lipids; thus, it can report the state of a single cell. Herein, we visualized the cell state transition during differentiation using Raman spectral imaging of cell nuclei in combination with principal component analysis. During differentiation, cell populations with a seemingly homogeneous cell state before differentiation showed heterogeneity at the early stage of differentiation. At later differentiation stages, the cells returned to a homogeneous cell state that was different from the undifferentiated state. Thus, Raman spectral imaging enables us to illustrate the disappearance and reappearance of an attractor in a differentiation landscape, where cells stochastically fluctuate between states at the early stage of differentiation.
Reconstitution of functional interleukin 2 receptor complexes on fibroblastoid cells: involvement of the cytoplasmic domain of the gamma chain in two distinct signaling pathways. (1993)

We have previously shown that the interleukin 2 (IL-2) receptor gamma chain is a member of the cytokine receptor superfamily and is indispensable for the formation of receptor complexes with high and intermediate affinities for IL-2. The present study demonstrates that the alpha beta gamma heterotrimer and beta gamma heterodimer complexes of IL-2 receptor reconstituted on murine fibroblast L929 cells can transduce IL-2-mediated signals for activation of tyrosine kinase and for induction of c-myc, c-fos, and c-jun expression. A mutant of the gamma chain lacking the C-terminal 68 amino acids in its cytoplasmic region showed a loss of such signal-transducing ability when incorporated into the IL-2 receptor complexes but brought no effect on IL-2 binding and IL-2 internalization. Another mutant, with a C-terminal deletion of 30 amino acids, retained the ability to activate a tyrosine kinase and to induce c-myc expression but lost the ability to induce c-fos and c-jun expression. These results suggest that at least two distinct signals, one for c-myc induction, which parallels tyrosine kinase activation, and the other for c-fos and c-jun induction, can be transduced from the IL-2 receptor complexes reconstituted on fibroblastoid cells.

Opioid Guidelines in the Management ofChronic Non-Cancer Pain (2006)

These guidelines evaluated the evidence for the use of opioids in the management of chronic non-cancer pain and recommendations for management. These guidelines are based on the best available scientific evidence and do not constitute inflexible treatment recommendations. Because of the changing body of evidence, this document is not intended to be a "standard of care."
Neuroprotective Effects of MK-801 and Catecholamine Release in the Central Nervous System (2004)

We read with great interest the recent article by Gerriets and colleagues 1 dealing with the neuroprotective effects of MK-801, the N-methyl-D-aspartate (NMDA) receptor antagonist, in the different rat stroke models for the permanent middle cerebral artery occlusion (MCAO).The results of their presented study demonstrated that, because hypothalamic damage and subsequent hyperthermia can confound the results, the macrosphere MCAO models without hypothalamic damage may be more appropriate to study the neuroprotective effects of MK-801 than the suture MCAO and the macrosphere MCAO models with hypothalamic infarction.Several studies have reported the mechanisms for the neuroprotective effects of MK-801 in the central nervous system.In a study we presented earlier, changes in norepinephrine (NE) release evoked by L-glutamate was investigated in rat central nervous system. 2 In an in vitro study, we showed that L-glutamate increased the release of NE from rat medulla oblongata, and further observed that the facilitative effect of L-glutamate on NE release was more pronounced in spontaneously hypertensive rats than in normotensive rats.In addition, it was demonstrated that MK-801 significantly reversed the increase in NE release evoked by L-glutamate.It would be possible that the sympatholytic action might partially explain the neuroprotective effects of MK-801 against hypertension and other neurotoxic disorders.In the ischemic neuronal models, Nakai et al 3 showed that ischemia significantly increased NE release in rat spinal cord.They also demonstrated that MK-801 suppressed the release of NE and glutamate produced by ischemia.The finding suggests that glutamate release and NMDA receptors may be involved in the acute effect of oxygen and glucose deprivation on the excessive release of NE in the ischemic regions.It was also reported that in the unilateral brain ischemia model induced by injecting microspheres into the left internal artery of the rat, the embolization caused significant depletion of catecholamine levels in the injured hemisphere. 4herefore, we would like to know the magnitude of the changes in the content or release of catecholamines and glutamate in the injured regions of the macrosphere MCAO models without hypothalamic damage.Further studies should be performed to assess more thoroughly the relationships between brain ischemia and neuroprotective effects of MK-801.
Cat 6 mo increases symptoms: online physician charting and more. (1995)

The physicians of the Children's Asthma Center and the computer scientists of Information Services at Texas Children's Hospital set out to design a system that is comfortable to use, structured enough to effectively measure outcomes, yet flexible enough to conserve the individuality of the patient. To achieve these goals, we examined how the differential diagnosis process is applied to clinical decision making and implemented it in a clinical workstation. Unique patterns representing the state of the patient's disease are formed by dynamically selecting pertinent sets of observations, assigning attributes to these observations, and describing relationships between observations and/or sets of observations.
The tone system of Kim Thượng Mường: an experimental study of fundamental frequency, duration, and phonation types (2016)

This is a study of the tone system of the Mường dialect of Kim Thượng (province of Phu Thọ, Vietnam). Distributional analysis – a classical procedure in linguistic fieldwork – brings out five tones on smooth syllables, and two tones on stopped syllables. These tones form the topic of an experimental phonetic study. Special attention is devoted to one of the tones of smooth syllables (labelled Tone 4), which is glottalized near the beginning of the rhyme. Audio and electroglottographic recordings allow for the measurement of fundamental frequency and for an estimation of the glottal open quotient, a parameter that offers indications on phonation type. The study addresses challenges linked to the quantitative study of glottalization, in order to propose a detailed picture of how tones pattern in terms of fundamental frequency, duration, and phonation types.
The real homotopy-based method for computing solutions of electric power systems (2003)

Presents a real homotopy-based method to calculate the roots of any system of polynomial equations in n real variables. This method eliminates some of the computational effort required in the existing homotopy- and imbedding-based continuation methods. The method allows for the computation of real solutions of even large-sized deficient polynomial systems. As an example, the method is applied to the load flow analysis of power systems.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
<i>Dmp1</i> is haplo-insufficient for tumor suppression and modifies the frequencies of <i>Arf</i> and <i>p53</i> mutations in <i>Myc</i>-induced lymphomas (2001)

Loss of Dmp1, an Arf transcriptional activator, leads to spontaneous tumorigenesis in mice, causing death from various forms of cancer by two years of age. Retention and expression of the wild-type Dmp1 allele in tumors arising in Dmp1(+/-) mice demonstrate that Dmp1 can be haplo-insufficient for tumor suppression. The mean latency of E(mu)-Myc-induced B-cell lymphomas is halved on a Dmp1(-/-) or Dmp1(+/-) genetic background. Although p53 mutations or Arf deletion normally occur in approximately 50% of E(mu)-Myc-induced lymphomas, Dmp1 loss obviates selection for such mutations, indicating that Dmp1 is a potent genetic modifier of the Arf-p53 pathway in vivo.
Road Transport: Options for Greenhouse Gas Mitigation (1992)

The method for estimating the future fuel consumed and therefore greenhouse gases from cars and trucks are found on the calculation of the aggregate performance of the vehicle population and its dynamics. Projections made are based on studies of the probable improvement in fuel consumption of new generations of cars and trucks. Alternative fuels are also examined including methanol as M85, ethanol as E15 for cars and methane gas (from biomass or natural gas) and M85 for trucks. These are the only fuels which are likely to lead to greenhouse gas reductions in the foreseeable future. It is concluded that the alternative fuels can play significant roles in reducing oil consumption but their contributions to reduced greenhouse gas emissions would be negligible to marginal. It would be better to focus attention on improvements to vehicle fuel efficiency and the infrastructure in which they operate. Strategies, which reduce travel demand by encouraging increased vehicle occupancy, by pricing policies or other methods and accelerated fleet turnover will all be needed if the Toronto accord is to be met in terms of carbon dioxide reductions from petrol fuelled vehicles. There seems even less opportunity for reducing diesel fuel consumed by road transport.
Study of main flux saturation effects in field-oriented induction motor drives (2003)

Effects caused by the variable degree of main flux saturation in induction machines with field-oriented control are considered. An indirect vector controller with a fixed value of magnetizing inductance is assumed, and the influence of variable saturation in steady-state and during transients is investigated. It is shown that the saturation effect is likely to be pronounced during operation in the field-weakening region, while its influence is small in the constant flux region if the value of magnetizing inductance in the controller is correctly set. Experimental identification of the rotor time constant in the field-weakening region is performed, and the results are presented. A modified flux calculator is derived, which can provide satisfactory operation in the field-weakening region. Its structure involves the magnetizing curve of the machine. The proposed flux calculator is verified by digital simulation.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Interplay Between Kinetic Inductance, Nonlinearity, and Quasiparticle Dynamics in Granular Aluminum Microwave Kinetic Inductance Detectors (2019)

Microwave kinetic inductance detectors (MKIDs) are central equipment in radioastronomy, thanks to their ease of fabrication and potential for multiplexing, which allow for millimeter-wavelength cameras with thousands of pixels. However, increasing their kinetic inductance to obtain maximum responsivity degrades their performance, due to the onset of nonlinearities. This work determines the optimum working point of MKIDs by taking into account the interplay between these two competing factors. It is also found that a lower-gapped ground plane can act as a phonon trap, providing lower noise-equivalent power in MKIDs limited by quasiparticle noise.

Regulation of the Escherichia coli glyA gene by the purR gene product (1990)

The purine regulon repressor protein, PurR, was shown to be a purine component involved in glyA regulation in Escherichia coli. Expression of glyA, encoding serine hydroxymethyltransferase activity, was elevated in a purR mutant compared with a wild-type strain. When the purR mutant was transformed with a plasmid carrying the purR gene, the serine hydroxymethyltransferase levels returned to the wild-type level. The PurR protein bound specifically to a DNA fragment carrying the glyA control region, as determined by gel retardation. In a DNase I protection assay, a 24-base-pair region was protected from DNase I digestion by PurR. The glyA operator sequence for PurR binding is similar to that reported for several pur regulon genes.
Simultaneous Determination and Pharmacokinetic Study of Metformin and Rosiglitazone in Human Plasma by HPLC-ESI-MS (2011)

A fast, sensitive and specific high-performance liquid chromatography tandem mass spectrometry method was developed for simultaneous determination of metformin and rosiglitazone in human plasma. With phenformin as an internal standard, the analysis was carried out on a C(18) column (50 mm × 2.1 mm, 3.5 μm) using a mobile phase consisting of acetonitrile-10 mM ammonium acetate (20:80, v/v). The detection was performed by tandem mass spectrometry via electrospray ionization. Linear calibration curves were obtained in the concentration of 1.054-263.5 ng/mL for rosiglitazone and 4.040-5050 ng/mL for metformin. The method was applicable to clinical pharmacokinetic study of metformin and rosiglitazone in healthy volunteers following oral administration.

Different Amino Acid Substitutions at the Same Position in Rhodopsin Lead to Distinct Phenotypes (2006)

Different amino acid substitutions at position 90 of rhodopsin can lead to night blindness or retinitis pigmentosa. The data suggest that the property of the substituted amino acid distinguishes between the phenotypes.
Insensitive Job Assignment With Throughput and Energy Criteria for Processor-Sharing Server Farms (2013)

We study the problem of stochastic job assignment in a server farm comprising multiple processor-sharing servers with various speeds and finite buffer sizes. We consider two types of assignment policies: without jockeying, where an arriving job is assigned only once to an available server, and with jockeying, where a job may be reassigned at any time. We also require that the underlying Markov process under each policy is insensitive. Namely, the stationary distribution of the number of jobs in the system is independent of the job size distribution except for its mean. For the case without jockeying, we derive two insensitive heuristic policies: One aims at maximizing job throughput, and the other trades off job throughput for energy efficiency. For the case with jockeying, we formulate the optimal assignment problem as a semi-Markov decision process and derive optimal policies with respect to various optimization criteria. We further derive two simple insensitive heuristic policies with jockeying: One maximizes job throughput, and the other aims at maximizing energy efficiency. Numerical examples demonstrate that, under a wide range of system parameters, the latter policy performs very close to the optimal policy. Numerical examples also demonstrate energy/throughput tradeoffs for the various policies and, in the case with jockeying, they show a potential of substantial energy savings relative to a policy that optimizes throughput.
Effect of alpha-difluoromethylornithine alone and in combination with doxorubicin hydrochloride, cis-diamminedichloroplatinum (II), and vinblastine sulfate on the growth of P3J cells in vitro. (1986)

alpha-Difluoromethylornithine (DFMO), an irreversible inhibitor of ornithine decarboxylase, was examined as a single and combined agent in growth studies using P3J, a Burkitt's lymphoma cell line. Used alone, DFMO (greater than or equal to 50 micrograms/ml; 0.21 mM) prevents cell proliferation in liquid culture and reduces the number and size of colonies that form in a two-layer soft agar system. In combination studies in which the soft agar system was used, DFMO was used at 15 and 25 micrograms/ml, concentrations which reduced the number of colonies to approximately 65 and 50%, respectively, of control plates. When doxorubicin hydrochloride (Adriamycin) was combined with DFMO, synergistic effects were noted at both DFMO concentrations. Cisplatin and DFMO were synergistic at the higher DFMO concentration and were supraadditive at 15 micrograms DFMO/ml. Combination studies using vinblastine sulfate (Velban) with DFMO did not deviate significantly from the predicted additive response.
Charge‐Tunable Autoclaved Silk‐Tropoelastin Protein Alloys That Control Neuron Cell Responses (2013)

Tunable protein composites are important for constructing extracellular matrix mimics of human tissues with control of biochemical, structural, and mechanical properties. Molecular interaction mechanisms between silk fibroin protein and recombinant human tropoelastin, based on charge, are utilized to generate a new group of multifunctional protein alloys (mixtures of silk and tropoelastin) with different net charges. These new biomaterials are then utilized as a biomaterial platform to control neuron cell response. With a +38 net charge in water, tropoelastin molecules provide extraordinary elasticity and selective interactions with cell surface integrins. In contrast, negatively charged silk fibroin protein (net charge -36) provides remarkable toughness and stiffness with morphologic stability in material formats via autoclaving-induced beta-sheet crystal physical crosslinks. The combination of these properties in alloy format extends the versatility of both structural proteins, providing a new biomaterial platform. The alloys with weak positive charges (silk/tropoelastin mass ratio 75/25, net charge around +16) significantly improved the formation of neuronal networks and maintained cell viability of rat cortical neurons after 10 days in vitro. The data point to these protein alloys as an alternative to commonly used poly-L-lysine (PLL) coatings or other charged synthetic polymers, particularly with regard to the versatility of material formats (e.g., gels, sponges, films, fibers). The results also provide a practical example of physically designed protein materials with control of net charge to direct biological outcomes, in this case for neuronal tissue engineering.
