High-flux isobutanol production using engineered Escherichia coli: a bioreactor study with in situ product removal (2011)

Promising approaches to produce higher alcohols, e.g., isobutanol, using Escherichia coli have been developed with successful results. Here, we translated the isobutanol process from shake flasks to a 1-L bioreactor in order to characterize three E. coli strains. With in situ isobutanol removal from the bioreactor using gas stripping, the engineered E. coli strain (JCL260) produced more than 50 g/L in 72 h. In addition, the isobutanol production by the parental strain (JCL16) and the high isobutanol-tolerant mutant (SA481) were compared with JCL260. Interestingly, we found that the isobutanol-tolerant strain in fact produced worse than either JCL16 or JCL260. This result suggests that in situ product removal can properly overcome isobutanol toxicity in E. coli cultures. The isobutanol productivity was approximately twofold and the titer was 9% higher than n-butanol produced by Clostridium in a similar integrated system.

Concurrent Reinforcement Learning from Customer Interactions (2013)

In this paper, we explore applications in which a company interacts concurrently with many customers. The company has an objective function, such as maximising revenue, customer satisfaction, or customer loyalty, which depends primarily on the sequence of interactions between company and customer. A key aspect of this setting is that interactions with different customers occur in parallel. As a result, it is imperative to learn online from partial interaction sequences, so that information acquired from one customer is efficiently assimilated and applied in subsequent interactions with other customers. We present the first framework for concurrent reinforcement learning, using a variant of temporal-difference learning to learn efficiently from partial interaction sequences. We evaluate our algorithms in two large-scale test-beds for online and email interaction respectively, generated from a database of 300,000 customer records. Copyright 2013 by the author(s).
The Implementation of Poisson Field Analysis Within FLUENT to Model Electrostatic Liquid Spraying (2007)

The process of electrostatic liquid spraying involves a combination of hydrodynamics, aerodynamics and electrostatics. Many parameters affect the process such as atomizing air pressure, liquid flow rate, nozzle-to-target distance, droplet size, charge-to-mass ratio, etc. The mechanical portion can be directly modeled with the computational fluid dynamics software, FLUENT. Although this software does not provide a direct solution for the electrostatic field, its user-defined functions can be used to solve the Poisson field by incorporating it into the general scalar transport equations within FLUENT. This enables the calculation of the electrostatic force on the charged droplets. The key to this technique is to find the space charge density for different charging models. An air-assisted electrostatic induction charging spray nozzle was modeled for both flat and spherical targets. Coupling between the airflow phase, the droplet discrete phase and the electrostatic field yields the trajectories of the charged droplets. Parameters such as droplet size, charge-to-mass ratio and nozzle-to-target distance were varied to demonstrate their effects on the motion of the charged droplets. The results show that the spray cloud expands with increased droplet charge-to-mass ratio and nozzle-to-target distance due to increased space charge. Thus they need to be independently controlled in order to increase the transfer efficiency and reduce drift.
Can Platinum Scale for PEC Hydrogen Evolution at the Terawatt Level? (2016)

Recent years has seen enormous and impressive progress in the search for non-precious hydrogen evolution reaction (HER) catalysts for both electrolysis and photoelectrochemical water splitting (PEC) with the molybdenum sulfide– and the cobalt phosphide families of HER catalysts showing great potential [1]. Despite the progress, no non-precious catalyst which matches platinum in HER performance has yet been found. To a large degree, the hunt for non-precious HER catalysts is motived by the notion that the physical scarcity and high price of platinum precludes it from usage on the terawatt scale. Using numerical modelling supported by benchmarking experiments on very well-defined platinum-based PEC electrodes we demonstrate that platinum in principle offers sufficiently fast kinetics to be useful on the terawatt level. As may be seen in the insert in figure 1 just 54 tons of platinum (which corresponds to ca. 30% of the global annual production [2]) would in principle be enough to support 1 TW of HER at a PEC current density of 10 mA/cm2 at a modest overpotential of 50 mV.[3] We discuss the platinum requirement under different assumptions and also the potential problems of using platinum in real-world PEC systems.

Tratamientos y vacunas para las infecciones bacterianas emergentes: aprendamos del Staphylococcus aureus resistente a meticilina (2006)

Pocas infecciones bacterianas emergentes han tenido un impacto mas espectacular en los anos recientes que la debida al Stpahylococcus aureus resistente a meticilina (MRSA). Las infecciones por S. aureus han constituido un grave problema sanitario para la humanidad durante milenios. El descubrimiento de la penicilina fue inicialmente un gran adelanto para combatir estas infecciones, pero rapidamente se desarrollo la resistencia a la penicilina a traves de la produccion de beta lactamasa por el S. aureus. Posteriormente se creo la meticilina, una penicilina estable frente a la beta lactamasa, que fue utilizada con exito contra el S. aureus. La resistencia a meticilina aparecio en 1961 [1], pero la infeccion por MRSA siguio siendo durante muchos anos casi exclusivamente nosocomial. Ya en los anos ochenta se notificaron brotes de MRSA contraido en la comunidad (CC-MRSA) [2], pero el CC-MRSA siguio siendo un fenomeno relativamente insolito hasta finales de los noventa, cuando empezaron a aparecer informes de brotes de CCMRSA [3,4] y distintos sindromes clinicos asociados con CC-MRSA (forunculosis y neumonia necrosante grave) [5,6]. El CC-MRSA es ahora un patogeno de gran importancia en muchas areas del mundo. La publicacion de los genomas completos de distintos aislados de MRSA nosocomiales [7,8], CC-MRSA [9] y S. aureus sensible a meticilina contraido en la comunidad (CC-MSSA) [7] ha aumentado en gran medida el conocimiento de las diferencias y las similitudes entre CC-MRSA, MRSA nosocomial y MSSA y los posibles papeles de los distintos factores de virulencia. La biologia molecular ha desempenado un papel critico en la distincion de las infecciones por CC-MRSA de las infecciones nosocomiales por MRSA y ha ofrecido perspectivas de los posibles mecanismos patogenicos
Accurate Bitrate Model and Greedy-Based Rate Controller for Low Delay Video Transmission (2011)

We develop a <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">q</i> -domain characteristic-based rate model for video transmission. Specifically, we extract three characteristics from the quantized discrete cosine transform spectra to construct an accurate rate-quantization (R-Q) model. Moreover, the extraction of the proposed characteristics requires only simple additive operations (additions, subtractions, and comparisons) and few multiplications. Based on the <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">q</i> -domain characteristic-based bitrate model, we develop an efficient two-level greedy-based rate controller for low delay video transmission. Extensive experimental results show that due to the efficiency and accurate estimation of both macroblock and frame-level R-Q models, the proposed rate controller better maintains the source bitrate to meet a predefined buffer delay time, and substantially enhances visual quality as compared with other rate controllers.
Combining Advantages - Unified Data Stores in Global Enterprises (2008)

Nowadays, data is heterogeneously stored across various data silos in global enterprises. For instance, OLAP profits in terms of performance from data immanent optimizations within the silo. We motivate the use of unified, enterprise-wide data stores which built the basis for combining data from different sources in arbitrary ways while eliminating redundancies. Without replicas all data operations, e.g. ad-hoc operational reporting, perform directly on real-time business data. The need for extracting data from various silos in preparation for reporting vanishes. A unified store consumes less system resources while hard disk and main memory capacity are used more efficiently. We analyze demands of applications in global enterprises and introduce a layered model. Our architecture enables rapid development of optimized applications. The data persistence becomes part of the infrastructure comparable to the network stack in network applications: it is no longer implemented solely for every application.
Pulswechselrichter (2012)

Um Drehfeldmaschinen mit einer frequenzvariablen Spannung zu versorgen, werden meistens Pulswechselrichter mit eingeprägter Zwischenkreisspannung verwendet. Im Leistungsbereich bis etwa 3MW werden die Umrichter häufig als Zweipunkt-Wechselrichter ausgeführt. Bei höheren Leistungen oder höheren Zwischenkreisspannungen (> 3k V) kommen auch Schaltungskonzepte mit 3 oder 5 Spannungsstufen, sogenannte Drei- oder Fünfpunkt-Umrichter, zum Einsatz. In diesem Kapitel werden Aufbau und Arbeitsweise sowie Steuerverfahren von Zweipunkt-Pulswechselrichtern erläutert. Für weitere Details zu Pulswechselrichtern sei auf die Literatur verwiesen [16].
Live-virus PE vaccine limitations: Dangers, advantages of new product against pneumoencephalitis (1948)

Vaccinating against pneumoencephali-tis—Newcastle disease, pneumo, PE—with the live-virus vaccines has been erroneously greeted as the final answer in the control of this disease. These live-virus vaccines are stop-gap measures. Little thought has been given to the many pitfalls and dangers of these products.

Mutational complexity increases in lung adenocarcinoma (LADC) with the development of brain metastasis (BM). (2018)

2067 Background: Up to 40% of LADC patients (pts) develop BM but little is known about the inciting molecular events. Methods: We compared mutational profiles of LADC BM pts with primary (P) LADC submitted to Caris Life Sciences from 2015-2017. Testing included next-generation sequencing (NGS) of 592 cancer-related genes, PD-L1 IHC and tumor mutational burden (TMB). NGS aberrations were test-defined as pathogenic (PATH), variants of undetermined significance or unclassified mutations (VUS). TMB was defined as: high (H; ≥17 mutations/megabase), intermediate (I; 7-16) and low (L; 0-6). Results: 145 BM (57% female (f)) and 1145 P (58% f) cases were identified; BM median age was 64 (range 31-86) vs. 70 (25-90) in P pts. BM had 55 PATHs (38% pts) in KRAS, 34 STK11 (23%), 17 EGFR (12%), 5 BRAF (3%); 3 were MET-amplified (2%), 3 ALK (2%) and 1 ROS1-rearranged (1%). Compared to P, more BM pts harbored STK11 PATHs (23% vs. 11%, P < 0.0001); no other difference in PATHs was observed. 143 BM and 1102 P pts had TMB data. BM cases were more-frequently TMB-H compared to P (39% (N = 56) vs. 12% (132), P < 0.0001) and less likely to be TMB-L (8% (12) vs. 33% (366), P < 0.0001). 131 (92%) BM pts were TMB-I or H. Of 142 BM and 1060 P with PD-L1 testing, incidence of ≥1% (46% BM vs. 49% P) and ≥50% (24% vs. 23%) cases were similar. 327 VUS in 28 receptor tyrosine kinases (RTK) were observed in 117 BM (median 1 (0-12)) vs. 1648 VUS in 807 P pts (median 1 (0-13); 79% vs. 70%, P = 0.007). RTK VUS more frequently observed in BM included: 51 EPHA3 VUS (17% pts vs. 8%. P = 0.0002), 25 EPHA5 (15% vs. 8%, P = 0.004), 26 NTRK3 (14% vs. 6%, P = 0.0002), 22 EPHB1 (13% vs. 6%, P = 0.0001) and 17 PDGFRA (12% vs. 5%, P = 0.0001). No significant difference was observed between BM specimen site and EGFR, KRAS, TMB and PD-L1 status. Conclusions: While classic LADC biomarkers including PD-L1, EGFR and KRAS were similar between BM and P cases, nearly 40% BM pts were TMB-H (≥25% more than P) and > 90% either TMB-I or H, indicating an increased mutational complexity in BM development, suggesting immune checkpoint inhibitor use. In addition to STK11 PATHs, RTK VUSs including NTRK3, EPHA3, EPHA5 and EPHB1 were more-frequently mutated and warrant further evaluation as biomarkers or targets in BM.

Abstract 3090: In vivo characterization of AMG 510 - a potent and selective KRASG12Ccovalent small molecule inhibitor in preclinical KRASG12Ccancer models (2019)

Abstract Somatic activating mutations of RAS family members are tumor driver mutations found in an estimated 21% of all cancers. Oncogenic KRAS mutations at residues G12, G13, and Q61 represent the most common RAS mutations found in solid malignancies. The prevalence of KRAS p.G12C tumors is ~13% of lung adenocarcinoma (including NSCLC), 3% of colorectal carcinoma (CRC), and 1% to 2% of numerous other solid tumors, representing an unmet medical need. We have developed AMG 510, an orally bioavailable, covalent inhibitor of KRASG12C with potent biochemical and cellular activity, and robust in vivo efficacy. AMG 510 inhibited SOS-catalyzed nucleotide exchange of recombinant mutant KRASG12C/C118A but had minimal effect on KRASC118A, which is wildtype at position 12. In cellular assays, AMG 510 covalently modified KRASG12C and inhibited KRASG12C signaling as measured by phosphorylation of ERK1/2 (p-ERK) in all KRAS p.G12C-mutant cell lines tested but did not inhibit p-ERK in cell lines with various other KRAS mutations. AMG 510 also selectively impaired viability of KRAS p.G12C mutant cell lines but did not affect cell lines with other KRAS mutations. In vivo pharmacodynamic assays demonstrated dose- and time-dependent inhibition of KRASG12Csignaling in human pancreatic and NSCLC tumor xenografts. Covalent modification of KRASG12C by AMG 510 was measured by mass spectrometry and correlated with p-ERK inhibition in tumors. AMG 510 significantly inhibited the growth of KRAS p.G12C xenografts and resulted in tumor regression. Combination treatment of AMG 510 with standard-of-care and targeted agents demonstrated enhanced tumor growth inhibition compared to either single agent. In a syngeneic model of KRAS p.G12C mutant cancer, AMG 510 treatment significantly inhibited tumor growth and caused regression. AMG 510 is currently in Phase 1, first-in-human clinical trials for patients with advanced solid tumors harboring a KRAS p.G12C mutation. Citation Format: Karen Rex, Anne Y.

Design and Development of the TerraStar Marginal-Terrain Amphibian (1968)

&lt;div class="htmlview paragraph"&gt;Many off-the-road mobility development programs have had as the principal objective a substantial improvement in soft-soil performance. This paper describes the evolution of the TerraStar marginal-terrain amphibian, which represents an effort to achieve this improvement without sacrificing “readability.” The TerraStar concept is based on the use of a new locomotion device called a major/minor wheel. Essentially an “interrupted” wheel, this device works down in soft soils much like a spaced-link track, and also provides wheeled vehicle performance on roads and highways, or hard ground.&lt;/div&gt; &lt;div class="htmlview paragraph"&gt;Aspects of the program related here include the use of scale-model tests in natural soils for preliminary design, the development of full-scale experimental vehicles, and the early results of field tests of the full-scale vehicles.&lt;/div&gt;
Photon counting type imaging spectrometer for solar soft x-rays (Conference Presentation) (2017)

The imaging spectroscopic observations for solar soft X-rays are expected to provide us novel and valuable information about the plasma activity in the solar corona, e.g., particle acceleration, heating, shock, etc. However, this type of observations has not been performed yet with enough energy, spatial, and temporal resolutions. In this situation, we plan to realize the imaging spectroscopic observations for solar soft X-rays with a high speed soft X-ray camera and grazing incidence mirrors. Our developing camera consists of a back-illuminated CMOS sensor. This censor has a sensitivity to soft X-rays (0.5 keV - 10 keV), and can perform continuous exposures of 1,000 frame per second for the imaging area of 1k x 100 pixels. We will mount this camera on the FOXSI-3 sounding rocket that is planned to be launched in the summer of 2018. By the combination of our camera and the X-ray mirror on the FOXSI, we can achieve an energy resolution of 0.2 keV, a spatial resolution of ~5 arcsec (1 arcsec sampling), and the temporal resolution of ~10 seconds in an energy range of 0.5 keV - 10 keV. In this presentation, we will explain the science goal, the instrumental design, and the developments of the solar soft X-ray imaging spectrometer.
