Abstract:
The extremely long underwater channel delay spread causes severe inter-symbol interference (ISI) for underwater acoustic communications. Passive time reversal processing (PTRP) can effectively reduce the channel time dispersion in a simple way via convolving the received packet with a time reversed probe signal (PS). However, the PS itself may introduce extra noise and interference (self-correlation of the PS). In this paper, we propose a virtual time reversal processing (VTRP) for single input single output (SISO) orthogonal frequency division multiplexing (OFDM) systems. It convolves the received packet with the reversed estimated channel, instead of the PS to reduce the interference. Two sparse channel estimation methods, matching pursuit (MP), and basis pursuit denoising (BPDN), are adopted to estimate the channel impulse response (CIR). We compare the performance of VTRP with the PTRP and without any time reversal processing through MATLAB simulations and the pool experiments. The results reveal that VTRP has outstanding performance over time-invariant channels.

Abstract:
Bioelectrochemical systems (BES) have the potential to deliver energy-neutral wastewater treatment. Pilot-scale tests have proven that they can operate at low temperatures with real wastewaters. However, volumetric treatment rates (VTRs) have been low, reducing the ability for this technology to compete with activated sludge (AS). This paper describes a pilot-scale microbial electrolysis cell (MEC) operated in continuous flow for 6 months. The reactor was fed return sludge liquor, the concentrated filtrate of anaerobic digestion sludge that has a high chemical oxygen demand (COD). The use of a wastewater with increased soluble organics, along with optimisation of the hydraulic retention time (HRT), resulted in the highest VTR achieved by a pilot-scale MEC treating real wastewater. Peak HRT was 0.5-days, resulting in an average VTR of 3.82 kgCOD/m3∙day and a 55% COD removal efficiency. Finally, using the data obtained, a direct analysis of the potential savings from the reduced loading on AS was then made. Theoretical calculation of the required tank size, with the estimated costs and savings, indicates that the use of an MEC as a return sludge liquor pre-treatment technique could result in an industrially viable system.

Abstract:
79 Background: Hospitalized patients on the heme/BMT service at our academic cancer center have historically not received pharmacologic VTE prophylaxis (VTEP) due to concerns regarding thrombocytopenia and bleeding risk. However, a retrospective review of heme/BMT admissions from 2009 to 2013 revealed that 59% of hospital-acquired VTE cases occurred at a platelet count > 50 x 10E9/L, suggesting missed opportunities for VTE prevention. Methods: To implement VTEP on the heme/BMT service, a multidisciplinary quality improvement team developed a pilot intervention with 5 strategies: 1) identification of heme/BMT-specific contraindications to VTEP, 2) standardized use of VTEP for all heme/BMT patients unless contraindications are present, 3) hold parameter for platelet count < 50 x 10E9/L within the VTEP order, 4) note template to document VTEP plan, and 5) provider, nurse, pharmacist, and patient education. We conducted audit and feedback every two weeks for two process measures: VTEP ordered for eligible patients (pre-pilot VTEP ordered for < 1%) and VTEP plan documented (pre-pilot documentation of 23%). Patients on therapeutic anticoagulation were excluded. We also tracked major bleeding events among patients receiving VTEP. Results: Since pilot implementation in July 2015, 105 patients admitted during audit periods met the inclusion criteria; 11 patients on therapeutic anticoagulation were excluded. Contraindications to VTEP were present for 56 patients, most commonly platelet count < 50 x 10E9/L (46%), central nervous system lymphoma (23%), and anticipated procedure (21%). Among the 49 eligible patients, VTEP was appropriately ordered for 42 (86%). VTEP plan was documented for 102 patients (97%). One VTEP-associated bleed occurred in a patient with recent polypectomy, prompting the addition of a new contraindication for recent procedures. Conclusions: Our multidisciplinary pilot successfully improved VTEP orders for eligible heme/BMT patients from < 1% to 86% and VTEP plan documentation from 23% to 97%. Rates of hospital-acquired VTE and major bleeding are being tracked prospectively to evaluate efficacy and safety.

Abstract Objective: To evaluate the efficacy of chemotherapy regimen containing pirarubicin on the patients with high-risk, relapse and refractory acute leukemia. Methods: 184 patients with high-risk, relapse and refractory acute leukemia were recruited and randomized to experiment group (111) and control group (73). The experiment group included 64 acute non-lymphocytic leukemia (ANLL) patients, 39 acute lymphocytic leukemia (ALL) patients and 8 mixed leukemia patients, and all received one of the following regimen: TA, VTP, VTLP or TAVP (T: pirarubicin, V: vincristine, P: prednisone, L: L-asparaginase). The patients in the control group received routine chemotherapy without pirarubicin. Results: the complete remission rate (CR) was significantly higher in pirarubicin-treated group than in control group either for all the patients (64.4% vs 43.8%, p<0.05) or for ANLL patients (68.1% vs 36.2%, p<0.05). At the same time bone marrow suppression was severer in pirarubicin-treated group than in control group (p<0.05). Conclusions: chemotherapy regimen containing pirarubicin is more effective than routine regimen without pirarubicin in the management of high-risk, relapse and refractory acute leukemia, especially in ANLL patients, although it induce severer but tolerable bone marrow suppression.

AbstractBackground:Patients suffering from traumatic brain injury (TBI) are at increased risk of venous thromboembolism (VTE). However, initiation of pharmacological venous thromboprophylaxis (VTEp) may cause further intracranial hemorrhage. We reviewed the literature to determine the postinjury time interval at which VTEp can be administered without risk of TBI evolution and hematoma expansion.Methods:MEDLINE and EMBASE databases were searched. Inclusion criteria were studies investigating timing and safety of VTEp in TBI patients not previously on oral anticoagulation. Two investigators extracted data and graded the papers’ levels of evidence. Randomized controlled trials were assessed for bias according to the Cochrane Collaboration Tool and Cohort studies were evaluated for bias using the Newcastle-Ottawa Scale. We performed univariate meta-regression analysis in an attempt to identify a relationship between VTEp timing and hemorrhagic progression and assess study heterogeneity using anI2statistic.Results:Twenty-one studies were included in the systematic review. Eighteen total studies demonstrated that VTEp postinjury in patients with stable head computed tomography scan does not lead to TBI progression. Fourteen studies demonstrated that VTEp administration 24 to 72 hours postinjury is safe in patients with stable injury. Four studies suggested that administering VTEp within 24 hours of injury in patients with stable TBI does not lead to progressive intracranial hemorrhage. Overall, meta-regression analysis demonstrated that there was no relationship between rate of hemorrhagic progression and VTEp timing.Conclusions:Literature suggests that administering VTEp 24 to 48 hours postinjury may be safe for patients with low-hemorrhagic-risk TBIs and stable injury on repeat imaging.

Abstract:
ABSTRACT Vibrio tubiashii, a causative agent of severe shellfish larval disease, produces multiple extracellular proteins, including a metalloprotease (VtpA), as potential virulence factors. We previously reported that VtpA is toxic for Pacific oyster (Crassostrea gigas) larvae. In this study, we show that extracellular protease production by V. tubiashii was much reduced by elevated salt concentrations, as well as by elevated temperatures. In addition, V. tubiashii produced dramatically less protease in minimal salts medium supplemented with glucose or sucrose as the sole carbon source than with succinate. We identified a protein that belongs to the TetR family of transcriptional regulators, VtpR, which showed high homology with V. cholerae HapR. We conclude that VtpR activates VtpA production based on the following: (i) a VtpR-deficient V. tubiashii mutant did not produce extracellular proteases, (ii) the mutant showed reduced expression of a vtpA-lacZ fusion, and (iii) VtpR activated vtpA-lacZ in a V. cholerae heterologous background. Moreover, we show that VtpR activated the expression of an additional metalloprotease gene (vtpB). The deduced VtpB sequence showed high homology with a metalloprotease, VhpA, from V. harveyi. Furthermore, the vtpR mutant strain produced reduced levels of extracellular hemolysin, which is attributed to the lower expression of the V. tubiashii hemolysin genes (vthAB). The VtpR-deficient mutant also had negative effects on bacterial motility and did not demonstrate toxicity to oyster larvae. Together, these findings establish that the V. tubiashii VtpR protein functions as a global regulator controlling an array of potential virulence factors.

Abstract:
National Quality Improvement Project (NSQIP) semiannual reports (SARs) revealed high observed to expected ratios for venous thromboembolic events (VTEs) on the surgical service. Press Ganey scores identified an area of particular weakness in shared decision-making in patient care. Patients reported little to no participation in shared decision-making. A performance improvement project was developed with a 2-fold objective: decrease the percentages of patients sustaining VTE through adequate screening and prophylaxis (VTEP) and to engage patients in shared decision-making to accept VTEP through enhanced patient-centered discussions and education on the risks and benefits of VTEP. A clinical pathway was developed to implement VTEP using a standardized risk assessment tool. Patient-centered discussion introduced VTEP and impact on perioperative safety. Results included telephone survey, NSQIP SARs, and Press Ganey patient experience survey. Using NSQIP data and a pathway developed for both VTE risk assessment and patient engagement, the authors observe immediate improvements in patient experience and decreased rates of VTE.

Abstract:
Abstract Valid-time-shifting (VTS) ensembles, either in the form of full ensemble members (VTSM) or ensemble perturbations (VTSP), were investigated as inexpensive means to increase ensemble size in the NCEP Global Forecast System (GFS) hybrid four-dimensional ensemble–variational (4DEnVar) data assimilation system. VTSM is designed to sample timing and/or phase errors, while VTSP can eliminate spurious covariances through temporal smoothing. When applying a shifting time interval (τ = 1, 2, or 3 h), VTSM and VTSP triple the baseline background ensemble size from 80 (ENS80) to 240 (ENS240) in the EnVar variational update, where the overall cost is only increased by 23%–27%, depending on the selected τ. Experiments during a 10-week summer period show the best-performing VTSP with τ = 2 h improves global temperature and wind forecasts out to 5 days over ENS80. This could be attributed to the improved background ensemble distribution, ensemble correlation accuracy, and increased effective rank in the populated background ensemble. VTSM generally degrades global forecasts in the troposphere. Improved global forecasts above 100 hPa by VTSM may benefit from the increased spread that alleviates the underdispersiveness of the original background ensemble at such levels. Both VTSM and VTSP improve tropical cyclone track forecasts over ENS80. Although VTSM and VTSP are much less expensive than directly running a 240-member background ensemble, owing to the improved ensemble covariances, the best-performing VTSP with τ = 1 h performs comparably or only slightly worse than ENS240. The best-performing VTSM with τ = 3 h even shows more accurate track forecasts than ENS240, likely contributed to by its better sampling of timing and/or phase errors for cases with small ensemble track spread.

Abstract:
Scheduling forms an important aspect of operating systems because it has a direct impact on system performance. Most existing general-purpose schedulers use a priority-based scheme to schedule processes. Such priority-based mechanisms cannot guarantee proportional fairness for every process. Proportional share schedulers maintain fairness among tasks based on given weight values. In both of these scheduler types, the scheduling decision is done perprocess. However, system usage policies are typically set on a per-consumer basis, where a consumer represents a group of related processes that may belong to the same application or user. The COPS framework uses the idea of consumer sets to group processes. Its design guarantees system usage per consumer, based on relative weights. We have added a share management layer on top of a proportional share scheduler to ease the administrative job of share assignment for these consumer sets. We have evaluated our system in real world scenarios and show that the CPU usage for consumer sets with CPU-bound processes complies with the administrator-defined policy goals.<br>Master of Science

Abstract:
Företaget är mitt uppe med att segmentera deras nätverk och anledningen till detta är att få en säkrare produktion med att skapa en kontrollerad och isolerad miljö, skydda mot spridning av virus och andra hot samt skapa en kostnadsbesparing genom att slippa uppdatera eller uppgradera utrustningar i onödan bara för att uppfylla nätverkspolicyn. För att underlätta företagets behov för segmentering har det här självständiga arbetet gått ut på att implementera VTP version 3 och MST. VTP skickar ut VLAN och MST uppdateringar runt i nätverket och underlättar vid användning av PVLAN. MST är ett Spanning Tree protokoll som gör det möjligt att mappa VLAN till instanser för på det sättet kunna spara CPU-belastning på switcharna samt att spara in på antal olika VLAN när PVLAN används. Metoden som användes var att sätta upp en testmiljö från backupper från riktiga nätet där det testades att implementera de nya protokollen samt att se hur de fungerade. En utvärdering av nätet gjordes där utvalda switchar och interfaces mättes innan implementationen för att senare jämföras med samma mätningar efter att implementationen var klar. Det visade sig att resultaten före implementeringen var så pass låga att implementeringen av MST sköts upp till att nätverkssegmenteringen var utförd. VTP version 3 implementerades utan problem och tre olika scenarier med färdiga konfigurationer skapades för att hjälpa företaget att ta steget över till MST i framtiden.<br>The company is on the verge of segmenting their network and the reasons for this are to get a more secure production by creating a controlled and isolated environment, protecting against the spread of virus and  other threats and aswell creating cost savings by not updating or upgrading unnecessary equipment just to meet the network policy. In order to facilitate the company's segmentation needs, this independent project has been about implementing VTP version 3 and MST. VTP sends out VLAN and MST updates around the network and ease the use of PVLAN. MST is a Spanning Tree protocol that enables VLAN to be mapped to instances to save CPU utilization on the switches as well to help load balance the network. The method used was to set up a test environment from backups from the real network where it was tested to implement the new protocols and to see how they acted. An evaluation of the network was made where selected switches and interfaces were measured before the implementation to be compared later with the same measurements after the implementation was completed. It turned out that the results before implementation were low enough that the implementation of MST was postponed until the network segmentation was completed. VTP version 3 was implemented without any problems and three different scenarios with complete configuration were created to help the company take the leap to MST in the future.

Abstract:
La maladie de Marek due à l’a-herpesvirus GaHV-2 (Gallid herpes virus) est un lymphome T du poulet contrôlable par vaccination. Nous avons recherché si l’activité télomérase et la transcription des gènes viraux étaient associées à la protection vaccinale. L’activité télomérase peut être considérée comme un marqueur de lymphomagenèse, corrélant avec la virulence des souches GaHV-2 parmi lesquelles le vaccin CVI988 induit une faible activité. Ce défaut d’activation ne semble pas lié à la mutation de la boîte H de vTR, présente uniquement dans deux lots de vaccins. La virulence des souches GaHV-2 a également un effet sur le taux de transcription des gènes viraux. La vaccination des poulets par la souche homologue Rispens CVI988 ou hétérologue HVT isolée du dindon provoque une réduction de l’activité télomérase et de la transcription des gènes viraux, après épreuve par une souche hypervirulente vvRB- 1B. Enfin, le vaccin CVI988 exerce, sur la transcription de vvRB-1B, un effet plus intense que celui d’HVT. L’activité télomérase et la transcription des gènes viraux peuvent ainsi être considérés comme de nouveaux critères de protection vaccinale<br>Marek’s disease is a chicken T lymphoma induced by the gallid herpesvirus type 2 (GaHV-2), an alphaherpesvirus. The disease is controlled through vaccination. In this work, we investigated whether telomerase activity and viral gene transcription were associated with protection against the GaHV-2 RB-1B strain in chickens vaccinated with Rispens CVI988 or the herpes virus of turkey (HVT). Telomerase activity seemed to be an appropriate marker of lymphoma and levels of viral transcription were correlated with the virulence of strains, the attenuated CVI988 strain inducing a low level of telomerase activity. We showed that the mutation in the H box of CVI988 vTR which was not shared by all CVI988 isolates could not account for this poor activation. Vaccinated birds had lower levels of telomerase activity and RB-1B viral transcription than unvaccinated chickens infected with RB-1B. The decrease in RB-1B viral transcription was more marked in chickens vaccinated with CVI988 than in those vaccinated with HVT. In conclusion, telomerase activity and gene transcription in challenge MDV strains are potential new reliable criteria of protection in vaccinated chickens

The Volatility Triggered Range Forward resembles a plain-vanilla forward whose delivery price is unknown initially and will be set once a pre-determined level of volatility threshold is reached in the exchange rate along the instrument’s life. Its payoff schedule can be set for any number of periods. Pricing and risk management is based on a trinomial lattice weighted between two possible regimes of volatility. These regimes are determined after a study of the BRL/USD series for the period between 2003 and 2009, based on a Switching Autoregressive Conditional Heteroskedasticity (SWARCH) model.

A demás el proceso de cobranza es rígido y poco dinámico, ya que las actividades están sumamente automatizadas lo que provoca que sea un proceso sin inteligencia, sin optimización, ya que en la actualidad no existe capacidad de hacer gestión de campañas de cobranza, de acuerdo a segmentos de clientes. Por lo anterior se propone como objetivo del proyecto mejorar, transparentar y flexibilizar el sistema de cobranza de VTR, mediante un rediseño de procesos que permita poseer mayor control y dar más valor a la cartera de clientes, mediante la gestión de cobranza focalizada a partir del comportamiento de los clientes. Para lograr estos objetivos se utilizará metodología idónea en el rediseño de procesos, junto a apoyo visual de modelos de procesos y de arquitectura, que ayuden a entender la situación actual. El foco del proyecto fue convertir al proceso de cobranza en un aporte estratégico para VTR. Se identificó información relevante para retroalimentar a otras áreas de la cadena de valor de VTR, pertenecientes al proceso de preventa y post venta de servicio. Esta retroalimentación permite generar mayor valor a la cartera de clientes de VTR, a partir del proceso de cobranza. El ahorro que se estima al optimizar las gestiones con el rediseño, en un escenario pesimista es de un 21% y en un escenario optimista es del 77% en gastos de cobranza, al establecer probabilidades de no pago de los clientes. En cuanto a las provisiones de deudas incobrables, se estiman ahorros del 0,33%, al identificar y cuantificar los errores en las condiciones de ingreso que posee el actual sistema de cobranza. La solución propuesta en este proyecto, implica la implementación de una herramienta habilitante, llamada Middleware, que no requiere un desarrollo costoso y permite flexibilizar y dinamizar el proceso. Se concluye que la cobranza es un servicio que las empresas de telecomunicaciones deben considerar antes del lanzamiento de un nuevo producto e integrarlo a la cadena de valor de la compañía.

Abstract:
As part of the study and development of a variable thermal resistor (VTR), we present an improved thermal resistance measurement method for the VTR in the presence of unwanted signal drifting. To measure the change of thermal resistance, instead of waiting for the steady state value of the temperature signal, we repeatedly measure only the early transient part of the thermal response signal and then fit to get thermal resistance estimation. The required lengths of measurement were studied for the tests with various thermal time constants. Using this method, we performed thermal switching tests with various material pairs in contact in order to find the material pair that minimizes thermal contact resistance.

Abstract:
The extremely-low carbon bainitic steel (ELCB steel) is a high strength steel with about 0.02 mass% or less carbon. In this research, unstable brittle crack arrest toughness of ELCB steel plates was investigated by temperature-gradient ESSO tests, compared with that of conventional TMCP steel plates. Both of ELCB and TMCP steel plates without pre-straining had sufficient crack-arrest toughness at 0°C. After 10% prestraining, the TMCP steel plate had not sufficient crack-arrest toughness at 0 °C . The ELCB steel plates, however, maintained high crack arrest toughness at 0°C. even after 10% pre-straining. ELCB steel were also different from TMCP steels in the correlation between transition temperature of crack arrest toughness and fracture appearance transition temperature (vTrs) obtained by Charpy impact test. When the vTrs of an ELCB steel and that of a TMCP steel were the same value, crack arrest toughness of an ELCB steel was higher than that of a TMCP steel. In the cross section of the ESSO test piece of the ELCB steels, many sub-cracks and micro-crack branching were observed. However, in the cross section of the ESSO test piece of the conventional TMCP steels, there were few subcracks and branching. Initiation of sub-cracks and branching around the main crack tip reduces the stress intensity factor of the main crack. It was considered that the above features of the ELCB steel were caused by initiation of sub-cracks and branching at the tip of the main brittle crack.
