Feasibility of using distributed Wireless Mesh Networks for medical emergency response. (2006)

Achieving reliable, efficient data communications networks at disaster site is a difficult task. Network paradigms such as Wireless Mesh Network (WMN) architectures are one paradigm for providing high bandwidth scalable data communication. WMNs are formed by self-organized wireless nodes that use multi-hop wireless relaying for data communications. In this paper describe our experience using mesh network architecture broadband network developed for homeland security and medical emergency applications. We briefly discuss the architecture and present the traffic behavioral observations made by a client server applications tested during a large scale homeland security drill. The results suggest that 802.11 mesh networks are feasible and scalable systems for field communications. We also present our traffic measurements based on which we make essential requirements for such medical emergency response networks.
Radial Line Slot Antenna for Space Use (2019)

A slot array design for a gain more than 44dBi RLSA is shown in this manuscript. A conventional slot array design procedure based on the Method of Moments was adopted, however needed to modify to adapt with a large number of radiating elements and a multilayer structure of the substrate. A fast analysis method based on a simplified however reliable equivalent model of the multilayer waveguide is developed to estimate the performance. Several RLSAs with a diameter of 900mm are fabricated and measured. In the optimum case, a directivity of 48.3dBi correspond to 73% aperture efficiency is obtained at 31.9GHz, where the measured gain is 44.6dBi.
Fusion of Data from Head-Mounted and Fixed Sensors (1999)

A methodology is developed to explicitly fuse sensor data from a combination of fixed and head-mounted sensors, in order to improve the registration of objects in an augmented reality system. The methodology was applied to the analysis of an actual experimental augmented reality system, incorporating an optical see-through head-mounted display, a head-mounted CCD camera, and a fixed optical tracking sensor. The purpose of the sensing system was to determine the position and orientation (pose) of a movable object with respect to the head-mounted display. A typical configuration was analyzed and it was shown that the hybrid system produces a pose estimate that is significantly more accurate than that produced by either sensor acting alone. Using only the fixed sensor, the maximum translational error in the location of an object with respect to the head-mounted display in any direction was 8.23 mm (corresponding to a 97% confidence interval). Using only the head-mounted sensor, the maximum translational error in any direction was 19.9 mm. By combining data from the two sensors, the maximum translational error was reduced to 1.47 mm. In order to fuse the pose estimates, the uncertainties are explicitly calculated, in the form of covariance matrices. A capability was also developed to visualize the uncertainties as 3D ellipsoids.
Effects of Centrally and Systemically Administered <i>L</i>-Tyrosine and <i>L</i>-Leucine on Ovarian Function in the Old Rat (1980)

The effects of centrally and systemically administered L-leucine and L-tyrosine on ovarian function were studied in the old female rat. Systemically administered L-tyrosine reinstated regular vaginal cycling and ovulation, whereas systemically administered L-leucine did not. When administered centrally, through an indwelling cannula in the medial preoptic area, neither L-tyrosine nor L-leucine altered the ovarian or vaginal condition of the old female. When these females were subsequently treated with L-dopa, both systemic and central application were found to reinstate ovarian cycles. Potential mechanisms of action at the level of CNS monoaminergic neurotransmission are discussed.
Eurotransplant randomized multicenter kidney graft preservation study comparing HTK with UW and Euro-Collins (1999)

The aim was to evaluate the effect of HTK compared to UW and Euro-Collins (EC) on the initial graft function and long term graft survival in two prospective randomized studies. Only kidneys from heart-beating, kidney-only or kidney + heart donors were eligible for entry. Initial non-function (INF) was defined as the absence of life-sustaining renal function, requiring dialysis treatment on two or more occasions, during the first week after transplantation. To evaluate the contribution of the preservation solutions on INF in relation to other factors, a multivariate, 2-step logistic regression model was used. Randomization was performed between July 1990 and September 1992. The UW-HTK study comprised 342 donors and 611 transplants (UW: 168 donors and 297 transplants, HTK: 174 donors and 314 transplants). In the EC-HTK study 317 donors and 569 transplants were included (EC: 155 donors and 277 transplants, HTK: 162 donors and 292 transplants). INF occurred in 33% of either HTK-(n = 105) or UW-(n = 99) preserved kidneys (P = NS), and in 29% of the HTK-(n = 85) and in 43% of the EC-(n = 119) preserved kidneys (P = 0.001). Multivariate analysis showed no significant influence of the preservation solution on the incidence of INF in the UW-HTK study, but factors contributing to INF were donor age, cause of death, retransplantation, and cold ischemic period. The EC-HTK study showed a significantly higher risk of INF, using EC as preservation, in addition to cold ischemic period and donor quality. The 3-year graft survival of HTK-preserved kidneys was 73%, compared to 68% for UW-preserved kidneys in the UW-HTK study (P = NS); while the 3-year graft survival of HTK preserved kidneys was 70% compared to 67% for EC-preserved kidneys in the EC-HTK study (P = NS). We can conclude that HTK is comparable to UW in its preservative abilities, using kidneys from heart-beating kidney-only donors, whereas EC as renal preservation solution should be avoided.
The terraSAR-X antenna system (2005)

TerraSAR-X is a space borne high resolution imaging synthetic aperture system, based on advanced active phased array technology. The paper presents an overview of the TerraSAR-X frontend and discusses the strategy for antenna testing, verification and in-orbit pattern prediction. As an integral part of this approach, an antenna model has been developed which allows, on the basis of embedded subarray measurements, the calculation of the overall antenna pattern for a given gain/phase setting of the T/R-modules.
Intraoperative Feeding Improves Calorie and Protein Delivery in Acute Burn Patients (2017)

Enteral nutrition support is a critical component of modern burn care for severely burned patients. However, tube feeds are frequently withheld during the perioperative period because of aspiration concerns. As a result, patients requiring multiple operative procedures risk accumulating significant protein-calorie deficits. The objective of this study was to describe our American Burn Association-certified burn center's experience implementing an intraoperative feeding protocol in severely burned patients defined as a cutaneous burn ≥20% TBSA. A retrospective review of patients with major thermal injuries (2008-2013). Thirty-three patients with an average of seven operating room trips (range, 2-21 trips) were evaluated. Seventeen patients received intraoperative enteral feeds (protocol group) and 16 patients did not (standard group). Feeding was performed using an enteral feeding tube placed postpylorically and was continued intraoperatively, regardless of operative positioning. There was no statistically significant difference in mortality between the groups (P = .62). No intraoperative aspiration or regurgitation events were recorded. The protocol group received significantly more calculated protein and caloric requirements, 98.06 and 98.4%, respectively, compared with 70.6 and 73.2% in the standard group (P < .001). Time to goal tube feed infusion rate was achieved on average 3 days sooner in the protocol group compared with the standard group (3.35 vs 6.18 days, P = .008). Early initiation and continuation of enteral feeds in severely burned patients led to higher percentages received of prescribed goal protein and caloric needs without increased rates of aspiration, regurgitation, or mortality.
Transport signatures of correlated disorder in a two-dimensional electron gas (2001)

We report electronic transport measurements on two-dimensional electron gases in a Ga[Al]As heterostructure with an embedded layer of InAs self-assembled quantum dots. At high InAs dot densities, pronounced Altshuler-Aronov-Spivak magnetoresistance oscillations are observed, which indicate short-range ordering of the potential landscape formed by the charged dots and the strain fields. The presence of these oscillations coincides with the observation of a metal-insulator transition, and a maximum in the electron mobility as a function of the electron density. Within a model based on correlated disorder, we establish a relation between these effects.
Altered tactile sensitivity in children with attention-deficit hyperactivity disorder (2017)

Attention-deficit hyperactivity disorder (ADHD) is characterized by an inability to concentrate, heightened activity, and hypermotoric behavior, but sensory (e.g., tactile) problems are common. The literature on tactile impairments in ADHD is limited, with most work employing clinical observations or questionnaires. We studied tactile processing in children with ADHD and hypothesized that children with ADHD would show reduced performance in tasks closely linked to inhibition. Sixty-seven children with ADHD and 62 typically developing children (TDC) performed a battery of tasks grouped in domains: simple and choice reaction time; static and dynamic detection threshold (probing feedforward inhibition); amplitude discrimination without adaptation and with dual and single-site adaptation (probing lateral inhibition and adaptation); sequential and simultaneous frequency discrimination (previously linked to GABA); and temporal order judgment with and without a synchronous carrier stimulus. Children with ADHD could discriminate different amplitudes without adaptation, suggesting lateral inhibition is intact, but were negatively affected in all adaptation conditions, whereas TDC were only affected during single-site adaptation. Children with ADHD also showed normal frequency discrimination. Children with ADHD showed slower reaction times and higher detection threshold, likely driven by IQ and inattention, because reaction time and detection thresholds correlated with IQ and subtle motor signs. Children with ADHD showed a pattern of altered tactile processing on specific tasks, suggesting that higher cognitive function and cortical mechanisms related to adaptation are affected in ADHD, but no clear conclusion can be drawn toward impaired inhibition.<b>NEW & NOTEWORTHY</b> This manuscript presents the first tactile psychophysical study testing different aspects of tactile processing in attention-deficit hyperactivity disorder (ADHD), using large cohort sizes of 67 children with ADHD and 65 Typically Developing Children. This study demonstrates impaired tactile processing in children with ADHD, on some, but not all tasks (showing this is not just due to attention), related to impaired cortical mechanisms. Furthermore, both IQ and soft motor skill abnormalities (common in ADHD) are correlated with tactile abnormalities.
[Changes in the surgical approach of impacted lithiasis in the terminal choledochus]. (1995)

Transduodenal sphincterotomy used to be was a common procedure when the surgeon couldn't remove stones from the terminal choledochus. We treated 6 patients in whom instead of a sphincterotomy, the stone was left in place and the duct drained with a T-tube. The first three cases were so managed because an emergency left no other option in the other three the decision was elective. Operative cholangiographies showed the impacted stones and in the postoperative cholangiographies, the stones had passed down to the stones had moved upward because of the decompression with the T-tube. The problem in all five patients with residual stone was easily solved. In one patient the stone was moshed down to the duodenum with biliary irrigation. The other four underwent transfistular extraction. Reviewing the morbility of transduodenal sphincterotomy we concluded that in an impacted stone it has currently few indications. In this era of "Biliary Perestroika" and specifically in emergencies or surgeons not fully experienced in transduodenal sphincterotomies, to put a T-tube and in the postoperative period complete others non surgical methods is an acceptable criteria. Also this approach can be applied to laparoscopic surgery when the operative cholangiography shows an unexpected biliary duct stone. The technique of leaving a transcistic catheter followed in the postoperative period by other therapeutic methods maintained in the discussion, could avoid a conversion to laparatomy or a laparoscopic choledochotomy, technique still in a developing period.
Visual Causality Analysis Made Practical (2017)

Deriving the exact casual model that governs the relations between variables in a multidimensional dataset is difficult in practice. It is because causal inference algorithms by themselves typically cannot encode an adequate amount of domain knowledge to break all ties. Visual analytic approaches are considered a feasible alternative to fully automated methods. However, their application in real-world scenarios can be tedious. This paper focuses on these practical aspects of visual causality analysis. The most imperative of these aspects is posed by Simpson' Paradox. It implies the existence of multiple causal models differing in both structure and parameter depending on how the data is subdivided. We propose a comprehensive interface that engages human experts in identifying these subdivisions and allowing them to establish the corresponding causal models via a rich set of interactive facilities. Other features of our interface include: (1) a new causal network visualization that emphasizes the flow of causal dependencies, (2) a model scoring mechanism with visual hints for interactive model refinement, and (3) flexible approaches for handling heterogeneous data. Various real-world data examples are given.
THE RELEASE OF A CORONARY VASODILATOR METABOLITE FROM THE GUINEA‐PIG ISOLATED PERFUSED HEART STIMULATED BY CATECHOLAMINES, HISTAMINE AND ELECTRICAL PACING AND BY EXPOSURE TO ANOXIA (1976)

1 A procedure involving two guinea-pig isolated hearts perfused in series is described for detecting in the recipient heart the release of a possible coronary vasodilator metabolite from the donor heart. 2 Adrenaline and isoprenaline stimulated the rate and force of contraction and produced a multiphasic coronary vascular response, the predominant phase of which was vasodilatation. When the beta-adrenoceptors of the recipient heart were blocked, stimulation of the donor heart by the catecholamines was associated with a coronary vasodilatation of the recipient heart. 3 Histamine stimulated rate and force of contraction and was predominantly coronary vasodilator. After blockade of histamine H1- and H2-receptors in the recipient heart, coronary vasodilatation followed increases in activity of the donor heart in response to histamine. 4 These vasodilator responses of the recipient heart were attributed to the release from the donor heart of a vasodilator metabolite by the increased activity. This is the proposed mechanism for the predominant coronary vasodilator response to catecholamines and histamine. 5 Periods of electrically-paced tachycardia and anoxia of the donor heart also led to the release of vasodilator activity. 6 The possible identity of the metabolite is discussed.
Human ribonuclease P: Subunits, function, and intranuclear localization (2002)

Catalytic complexes of nuclear ribonuclease P (RNase P) ribonucleoproteins are composed of several protein subunits that appear to have specific roles in enzyme function in tRNA processing. This review describes recent progress made in the characterization of human RNase P, its relationship with the ribosomal RNA processing ribonucleoprotein RNase MRP, and the unexpected evolutionary conservation of its subunits. A new model for the biosynthesis of human RNase P is presented, in which this process is dynamic, transcription-dependent, and implicates functionally distinct nuclear compartments in tRNA biogenesis.
ANALYSIS OF A DOUBLE-LAYERED VIVALDI ANTENNA INSIDE A METALLIC ENCLOSURE (2013)

A double-layered Vivaldi antenna enclosed by a metallic cylindrical cavity is investigated. The antenna is correlated to the same-size circular horn antenna to exploit the equivalent modal distribution of the Vivaldi-cavity antenna. It is shown that the TM 11 and TE 11 are the dominant modes and the proposed antenna operates similar to a dual-mode conical horn. The antenna is fabricated and successfully tested. The radiation characteristics, mutual coupling, as well as cross-polarization level are compared to a similarly sized Vivaldi without any metallic enclosure.
Molecular cloning and characterization of beluga whale (Delphinapterus leucas) interleukin-1beta and tumor necrosis factor-alpha. (2001)

Interleukin-1beta (IL-1beta) and tumor necrosis factor-alpha (TNF-alpha) are cytokines produced primarily by monocytes and macrophages with regulatory effects in inflammation and multiple aspects of the immune response. As yet, no molecular data have been reported for IL-1beta and TNF-alpha of the beluga whale. In this study, we cloned and determined the entire cDNA sequence encoding beluga whale IL-1beta and TNF-alpha. The genetic relationship of the cytokine sequences was then analyzed with those from several mammalian species, including the human and the pig. The homology of beluga whale IL-1beta nucleic acid and deduced amino acid sequences with those from these mammalian species ranged from 74.6 to 86.0% and 62.7 to 77.1%, respectively, whereas that of TNF-alpha varied from 79.3 to 90.8% and 75.3 to 87.7%, respectively. Phylogenetic analyses based on deduced amino acid sequences showed that the beluga whale IL-1beta and TNF-alpha were most closely related to those of the ruminant species (cattle, sheep, and deer). The beluga whale IL-1beta- and TNF-alpha-encoding sequences were thereafter successfully expressed in Escherichia coli as fusion proteins by using procaryotic expression vectors. The fusion proteins were used to produce beluga whale IL-1beta- and TNF-alpha-specific rabbit antisera.

Autophagy: assays and artifacts (2010)

Autophagy is a fundamental and phylogenetically conserved self-degradation process that is characterized by the formation of double-layered vesicles (autophagosomes) around intracellular cargo for delivery to lysosomes and proteolytic degradation. The increasing significance attached to autophagy in development and disease in higher eukaryotes has placed greater importance on the validation of reliable, meaningful and quantitative assays to monitor autophagy in live cells and in vivo in the animal. To date, the detection of processed LC3B-II by western blot or fluorescence studies, together with electron microscopy for autophagosome formation, have been the mainstays for autophagy detection. However, LC3 expression levels can vary markedly between different cell types and in response to different stresses, and there is also concern that over-expression of tagged versions of LC3 to facilitate imaging and detection of autophagy interferes with the process itself. In addition, the realization that it is not sufficient to monitor static levels of autophagy but to measure 'autophagic flux' has driven the development of new or modified approaches to detecting autophagy. Here, we present a critical overview of current methodologies to measure autophagy in cells and in animals.
Quantitative prediction of NACK-oriented reliable multicast (norm) feedback (2003)

We have applied the concept of truncated exponential timers for efficient reliable multicast feedback suppression for cases of both multicast and unicast feedback channels. Unicast feedback operation for multicast transport is becoming a more prevalent concern with the advent of source specific multicast routing and asymmetric networks of offering forward-based multicast (e.g., satellite distribution network). We discuss our approach to the design and its integration with a working reliable multicast protocol. We then present simulation results demonstrating that observed implementation performance matches the analytically predicted performance. Finally, we formulate a quantitative predictor of reliable multicast protocol feedback traffic levels.
Genetic species identification in weatherfish and first molecular confirmation of Oriental Weatherfish Misgurnus anguillicaudatus (Cantor, 1842) in Central Europe (2017)

The Oriental Weatherfish is considered a globally invasive fish species. In Europe, several reported feral populations of Oriental Weatherfish display an overlapping distribution range with native weatherfish Misgurnus fossilis, a declining species of international conservation and aquatic management concern. Morphologically distinguishing the different weatherfish species can be difficult, as their coloration is highly variable, many species reveal high phenotypic plasticity, and morphological traits like coloration might be not obvious or might be degraded during field sampling and after preservation. Herein, we analysed suspicious weatherfish specimens from southern Germany, demonstrating the usefulness of molecular genetic species identifications in this genus. We present the first molecular genetic species record of Misgurnus anguillicaudatus in Central Europe, and confirm the range expansion of Oriental Weatherfish into the river Inn catchment in southern Germany. As accurate species identification is crucial both in the context of monitoring and conserving native endangered species, and in early detection and prevention of biological invasion, we suggest the standard use of genetic species identification if morphological traits are not obvious.
