A 3D approach to infrastructure-free localization in large scale warehouse environments (2016)

In this paper, we present a method for infrastructure-free localization of Automated Guided Vehicles (AGVs) in a warehouse environment. To accomplish this, our approach leverages 3D data for both mapping and feature segmentation. First, a 3D reconstruction of the warehouse is created to extract salient natural features - in this case the shelving uprights - as landmarks. Next, the map-based localization approach leverages 3D LIDAR to enable 3D feature-to-landmark matching which minimizes the potential for data association errors. In our experiments in a representative warehouse environment, we demonstrated a localization accuracy of approximately 2cm without the use of retroreflector targets. Furthermore, 100% of visible landmarks were detected and there were no false positives.
MicroRNA–194 Is A Target of Transcription Factor 1 (Tcf1, HNF1α) in Adult Liver and Controls Expression of Frizzled–6 (2011)

Our results support a role of miR-194 in liver tumorigenesis through its endogenous target Fzd6. These results may have important implications for Tcf1-mediated liver proliferation.
Performance comparison of RS-CC concatenated codes using NSC and RSC codes (2010)

In this paper, we show that the concatenated code of Reed-Solomon (RS) code and convolutional code (CC), especially, concatenated with recursive systematic convolutional (RSC) code, to have better BER performance than non-concatenated codes or concatenated code with non-systematic convolutional (NSC) code. By concatenating two different codes we can get the effect of improving total BER due to benefits of RS codes correcting burst errors that is occurred by decoding process of convolutional code.
Organic chemistry of binuclear metal centres. Part 6. µ-Vinylidene and µ-ethylidyne diruthenium complexes: crystal structures of cis-[Ru2(CO)2(µ-CO)(µ-CCH2)(η-C5H5)2] and cis-[Ru2(CO)2(µ-CO)(µ-CMe)(η-C5H5)2][BF4] (1983)

The dimetallacycles [Ru2(CO)(µ-CO){µ-C(O)C2HR}(η-C5H5)2](R = H or Ph) isomerise in boiling toluene to the µ-vinylidene complexes [Ru2(CO)2(µ-CO)(µ-CCHR)(η-C5H5)2], shown by a deuterium-labelling experiment to involve an intramolecular hydrogen shift. Protonation of the µ-CCH2 complex with HBF4·OEt2 gives the µ-ethylidyne species [Ru2(CO)2(µ-CO)(µ-CMe)(η-C5H5)2][BF4], which deprotonates readily when treated with water, triethylamine, or methyl-lithium; with NaBH4 the cation is attacked by hydride to produce the µ-ethylidyne complex [Ru2(CO)2(µ-CO)(µ-CHMe)(η-C5H5)2]. Successive addition of methyl-lithium and HBF4·OEt2 to [Ru2(CO)4(η-C5H5)2] also yields the complex [Ru2(CO)2(µ-CO)(µ-CMe)(η-C5H5)2][BF4], whose subsequent conversion to [Ru2(CO)2(µ-CO)(µ-CCH2)(η-C5H5)2] or [Ru2(CO)2(µ-CO)(µ-CHMe)(η-C5H5)2] provides an excellent route to these complexes. Similar successive addition of phenyl-lithium, HBF4·OEt2, and NaBH4 to [Ru2(CO)4(η-C5H5)2] gives [Ru2(CO)2(µ-CO)(µ-CHPh)(η-C5H5)2] in high yield. The molecular structures of cis-[Ru2(CO)2(µ-CO)(µ-CCH2)(η-C5H5)2] and cis-[Ru2(CO)2(µ-CO)(µ-CMe)(η-C5H5)2][BF4] have been determined by X-ray diffraction studies. Crystals of both compounds are monoclinic, space group P21/n with Z= 4 and unit-cell dimensions a= 8.620(6), b= 15.712(9), c= 10.844(8)Å, β= 92.57(4)° and a= 9.121(2), b= 9.724(3), c= 20.666(6)Å, β= 106.42(3)° respectively. The structures were solved by heavy-atom methods and refined by least squares to give final residuals R of 0.051 and 0.026 for 2 503 and 3 044 unique, observed, diffractometer data respectively. Both cis-[Ru2(CO)2(µ-CO)(µ-CCH2)(η-C5H5)2] and cis-[Ru2(CO)2(µ-CO)(µ-CMe)(η-C5H5)2]+ show approximate Cs symmetry in the solid state, with Ru–Ru single bond distances of 2.696(1) and 2.714(1)Å respectively. In both cases each ruthenium atom is co-ordinated by terminal carbonyl and η-cyclopentadienyl ligands in addition to bridging carbonyl and hydrocarbon (vinylidene and ethylidyne) groups. The geometry and orientation of the bridging vinylidene ligand is consistent with a C–C bond order of two [C–C 1.326(11)Å] and contact carbon bonding to the Ru2 fragment via donor and acceptor interactions of σ and π symmetry in the Ru2C plane. The µ-ethylidyne ligand in cis-[Ru2(CO)2(µ-CO)(µ-CMe)(η-C5H5)2][BF4] shows average Ru–C distances shorter than those of the η-vinylidene ligand in cis-[Ru2(CO)2(µ-CO)(µ-CCH2)(η-C5H5)2][1.937(4)vs. 2.030(7)Å], and has a longer C–C distance [1.462(6)Å] consonant with a C(sp)-C(sp3) single bond. These geometric features, and the reactivity of the cationic µ-ethylidyne complex towards nucleophiles, are explained in terms of a simple molecular orbital model.
Transiente Prozesse in resistiv schaltenden Speicherelementen auf ultimativer Zeitskala bis zum Sub-Nanosekunden-Bereich (2016)

The strong evolution of electronics and its rapid performance progress in the past decades call for ever faster, better scalable, more power efficient and low cost memory technology. The dominating contemporary memory types, dynamic random access memory (DRAM) and Flash, now approach the physical and technological limits beyond which no further scaling is possible. Hence, there is an urgent need for a successor technology. The redox-based resistive switching random access memory (ReRAM) is a novel memory type which is based on a two terminal device structure. The stored information is represented by the resistance of the device which can be switched between two or more different levels. The resistive switching is controlled by applying an appropriate voltage to the device, defined in amplitude and length. The findings presented up to now show a supreme performance of ReRAM. Excelling in speed, scalability, energy efficiency and endurance, ReRAM is a very promising candidate to replace both DRAM as well as Flash. In this thesis, transient processes of the resistive switching are studied at two extreme speeds: First, a slow electrocoloration of iron doped strontium titanate (Fe:STO) single crystals is investigated by means of high resolution transmission optical microscopy. The experiment makes the electro-chemical changes in the crystal visible and demonstrates the homogeneity of the redox processes at a maximum optical resolution down to 500 nm. As a model process, the electrocoloration is linked to the initial electroforming of a ReRAM cell.Second, resistive switching and kinetics of ReRAM devices are investigated. For the first time a multi-level resistive switching of tantalum oxide (TaOx) devices at sub-nanosecond times is presented and the switching kinetics on an extended time scale over 15 decades is demonstrated, performed on the same device. At the nanosecond range the switching event is determined from the pulse signal transients and the dependency of the switching time on the driving signal magnitude is shown. The ultra-fast performance of the TaOx ReRAM devices reaches the speed of the static random access memory (SRAM) but additionally benefits from the non-volatility. The write speed surpasses the concurrent DRAM and it is more than six orders of magnitude faster when compared to Flash. The presented study includes a design of the high-speed ReRAM device as well as a design and construction of a customized measurement setup.A connecting topic of this thesis is metrology. In regard of ReRAM characterization, correct measurement techniques represent a crucial prerequisite for valid results and a correct interpretation. Demonstrated testing of several commercial measurement instruments shows an incorrect operation, representing principal errors of the measurement and a potential risk for the device under test. The errors are analyzed in depth and subsequently a custom setup, optimized for the ReRAM testing, is presented.
RAPID ACCESS TO 2′-BRANCHED-CARBOCYCLIC NUCLEOSIDES AND THEIR 4′-EPIMERS FROM 2-ALKYL-CYCLOPENTENE-1-ONES (2005)

2-Methyl-2-cyclopentene-1-one was used as starting material in a novel route toward 2'-branchedcarbocyclic nucleosides. This methodology was efficiently adapted to the preparation of 4'-epicarbocycles. A series of this new class of molecules was synthesized as potential antiviral compounds.
Effect of Packaging Materials on Temperature Fluctuations in Frozen Foods: Mathematical Model and Experimental Studies (1986)

ABSTRACT An analytical solution of the conduction heat transfer equation was developed for prediction of temperature in frozen foods exposed to periodic environmental temperature fluctuations. The prediction model includes the effect of surface heat transfer resistances. Theoretical predictions were compared with experimental values recorded from frozen ice cream at different storage regimes. Slab‐shaped metal containers were used in the experiment. Surface heat transfer resistances were simulated with single layers of commercial packaging cardboard sheets and restricted air movement over the containers. A satisfactory agreement was obtained between predicted values and experimental data. Packaging materials coupled with a layer of stagnant air are effective barriers against thermal fluctuations.

Laboratory observation of hot bands of H+3 (1990)

The (2ν2,l=2←ν2), (2ν2,l=0←ν2), and (ν1+ν2←ν1) hot bands of H+3 were observed. The vibrationally hot ions were produced in a liquid nitrogen cooled 6 kHz ac discharge using gas mixtures of H2 and He. The spectra were detected in direct absorption using a newly extended tunable difference frequency spectrometer using both LiNbO3 and LiIO3 crystals as nonlinear optical elements. The range of this spectrometer is now ∼5300–∼1900 cm−1. The positions of the rovibrational transitions compare extremely well with the theoretical predictions of Miller and Tennyson. A vibrational temperature study of the discharge indicates a significant population inversion between the ν1 and ν2 levels.
Living ring opening metathesis polymerization of mesogenic norbornene derivatives (1994)

Abstract A new class of SCLCPs was prepared by polymerizing mesogenic norbornene derivatives using Mo(CHCMe 2 R)(N‐2,6‐C 6 H 3 ‐ i ‐Pr 2 )(O‐ t ‐Bu) 2 (R = CH 3 or Ph). Monomers based on norbornene ring systems were chosen because the rings are highly strained and therefore yield irreversible polymerizations. The Mo‐alkylidene initiators were chosen because they initiate norbornene derivatives relatively fast and quantitatively, and provide stable chain ends which have low reactivity to both the internal double bonds of the polymer backbone and the functional groups present in the monomers. The apparent absence of termination and transfer reactions in ROMP results in polymerizations which appear to be living, and the fast initiation and irreversible chain growth leads to polymers with narrow molecular weight distributions in which the degree of polymerization is controlled by the ratio of monomer to initiator used. The resulting well‐defined polymers were used to determine the most basic structure‐property relationships of this new class of SCLCPs. The thermotropic behavior of both terminally attached and laterally attached SCLCPs based on polynorbornene backbones becomes independent of molecular weight at approximately 25 repeat units. In addition, polydispersity was found to have no effect on the breadth of nematic phase transitions in the terminally attached polymers, with the transition temperature determined simply by the number average degree of polymerization.

The Lombard Effect's Influence on Automatic Speaker Verification Systems and Methods for its Compensation (2006)

Speaker identification/verification applications have progressed significantly during the last few years. Performance levels of between 70% -99% success in speaker recognition systems are normal, depending on the type of application and quality of the signal. Several techniques for robust speaker recognition have been developed. Until now, however, the problem posed by variations in speech characteristics due to acoustical noise has not been thoroughly investigated in the context of speaker recognition. The change a noisy acoustic environment can produce in speech signal parameters is known as the "Lombard effect." In this paper the Lombard effect's influence on speaker verification system performance is investigated and several compensation methods are proposed. The verification system is based on a 24 Gaussian mixture model (GMM) and speech feature orders of 12 to 60. It was found that, based on the mean Equal Error Rate (EER), verification performance deteriorated by 10.1% (from 3.8% to 13.9%) relative to speech verification in a normal environment due to the Lombard Effect. Two types of Lombard Effect compensation methods are proposed. The first is based on robust speech features that are resistant to the Lombard effect. The second is based on studying how the Lombard effect changes speech feature and then transforming the Lombard affected speech back to normal speech. The proposed methods significantly reduce speaker verification system error rates. An improvement in the EER of up to 5.4 % (from 13.5% to 8.5%) was achieved.
Versatile, Fully Automated, Microfluidic Cell Culture System (2007)

There is increasing demand for automated and quantitative cell culture technology, driven both by the intense activity in stem cell biology and by the emergence of systems biology. We built a fully automated cell culture screening system based on a microfluidic chip that creates arbitrary culture media formulations in 96 independent culture chambers and maintains cell viability for weeks. Individual culture conditions are customized in terms of cell seeding density, composition of culture medium, and feeding schedule, and each chamber is imaged with time-lapse microscopy. Using this device, we perform the first quantitative measurements of the influence of transient stimulation schedules on the proliferation, osteogenic differentiation, and motility of human primary mesenchymal stem cells.
Can We Approach a Zero Percent Infection Rate In Total Knee Arthroplasty? A Program To Achieve This Goal With Antimicrobial Agents (2022)

Periprosthetic joint infections (PJIs) are one of the most feared complications in the realm of adult reconstruction due to the substantial morbidity and mortality associated with these cases. Advancements in arthroplasty have been made across a variety of areas of interest including implant surfaces, implant design, material science, etc., but a focus on infection prevention and treatment is of utmost importance. A new technology has been created that targets biofilm and aims to prevent infection in total joint arthroplasty. In this manuscript we aim to describe the benefits of this technology and describe the ideal use in a case scenario format. We believe that with this technology that we can approach the goal of a zero periprosthetic infection rate.
Bromine-80m-labeled estrogens: Auger-electron emitting, estrogen receptor-directed ligands with potential for therapy of estrogen receptor positive cancers (1988)

To assess their possible use for estrogen receptor (ER)-directed radiotherapy of estrogen receptor-containing cancers, two estrogens were synthesized with the Auger electron-emitting nuclide bromine-80m and administered to immature female rats. Both the triphenylethylene-based estrogen, [80mBr]-2-bromo-1,1-bis(4-hydroxyphenyl)phenylethylene (Br-BHPE) and the steroidal estrogen [80mBr]17 alpha-bromovinylestradiol, showed substantial diethylstilbestrol-inhibitable localization only in the estrogen target tissues, the uterus, pituitary, ovaries, and vagina and, except for the liver and intestines, generally lower concentrations in all other tissues at both 0.5 and 2 h. The [80mBr]Br-BHPE (specific activity, 8700 Ci/mmol), was shown to bind specifically to the low salt extractable ER of the rat uterus. Comparing i.p., i.v., and s.c. administration of [80mBr]BHPE the i.p. route was found to be particularly advantageous to effect maximum, DES-inhibitable concentrations of radiobromine in the ER-rich target organs in the peritoneal cavity. When the tissue distribution of the [80mBr]Br-BHPE was compared with that of sodium bromide-80m, it was apparent that no substantial amounts of radiobromine were released from the bromoestrogen prior to its target tissue localization. The substantial concentration of these bromine-80m-labeled estrogens in ER-rich tissues, combined with previously reported evidence for the effective radiotoxicity of Auger electron-emitting nuclides within cell nuclei suggest a good potential for such ligands for therapy of ER positive cancers.
Experimental assessment of the microstructure evolution and liquidus projection in the Mo-rich Mo–Si–B system (2019)

The present work is focused on a deeper understanding of the microstructure evolution and the solidification reactions of alloys in the Mo-rich portion of the Mo–Si–B system. A number of 59 alloys were selected from the vicinity of the ternary eutectic point to carefully examine the Mo-rich liquidus surface. Therefore, the microstructural evolution of alloy compositions from different primary solidification areas was taken into account. Their solidification path was evaluated by employing the Alkemade theorem. The result is an experimentally based reassessment of the liquidus projection. Special attention had been payed to the Mo3Si primary solidification area and the MoSS–Mo5SiB2–Mo3Si ternary eutectic in the Mo-rich portion of the Mo–Si–B system. It could be shown that the primary Mo3Si phase region is larger as compared to present literature data. The eutectic point could be confirmed to contain 17 ± 1 at.% silicon and 7.5 ± 0.5 at.% boron. As the main outcome from the careful investigation of the solidification paths of numerous alloys a reconstructed liquidus projection is presented.

Preparation of the Color Films from Cellulose Derivatives in a Diacrylate Liquid (2019)

In this study, we fabricated the multi-colored films of lyotropic cholesteric liquid crystals (CLCs) prepared from a hydroxypropyl cellulose (HPC) derivative by photopolymerization of a diacrylate liquid monomer for color image applications. When a hydroxypropyl cellulose derivative tethering propionyl side chains (HPC-PrE) was completely dissolved in a liquid monomer of 1,4-bis(acryloyloxy)butane (BAOB) to prepare lyotropic CLC (HPC-PrE_BAOB), we could observe Bragg reflection in the visible wavelength range at room temperature. Photopolymerization of BAOB in the lyotropic CLC mixture gave rise to fabrication of robust solid-state CLC films with reflection colors. Furthermore, we found that the reflection wavelength is tunable by controlling the light intensity of irradiation UV light, thereby enabling the facile fabrication of multi-colored films by the photolithographic technique. The present report opens promising ways to design and produce intriguing photonic devices by utilizing the environmentally-friendly and safe natural polymer of cellulose.
Interface Heat Transfer of Horizontal Co-current Liquid-liquid Stratified Flow : 2nd Report, Entrance Region (1981)

Thermo-hybrodynamic characteristics of a stratified flow in a horizontal rectangular channel have been investigated experimentally and analytically, using liquid metal with a low melting point (Wood's metal ) and water as test fluids.In this report, the transition about macroscopic characteristics of fluid flow and heat transfer, that is the position of interface between both fluids, pressure drop and heat transmission coefficient through the interface etc., are studied experimentally in the entrance region.Both the mixing length model and the two-equation model considering a damped turbulent layer near the interface by surface tension, proposed in the previous report, are applied to analyse thermo-hydrodynamic behaviours in this system.The analytical results are compared with experimental ones and discussed to get better understandings of a liquid-liquid stratified flow in the entrance region.
