Direct reaction of photogenerated diarylcarbenes at square-planar rhodium(i) (2004)

A series of carbene complexes RhCl(CR'2)(PR3)2(R=Ph, Tol, Me, R'= Ph and Tol) have been synthesised through direct reaction of photochemically generated free diarylcarbene with RhCl(CO)(PR3)2. This route to carbene complexes demonstrates the reactivity of simple diarylcarbenes towards transition metal complexes. The reactivity of some of these complexes towards H2, C2H4 and Et3SiH has been investigated.
Generation and analysis of transgenic mice expressing P216L-substituted rds/peripherin in rod photoreceptors. (1997)

The phenotype in P216L-transgenic mice on an rds-/+ genetic background probably is caused by a combination of two genetic mechanisms: a direct dominant effect of the P216L substituted protein, and a reduction in the level of normal rds/peripherin. The expression pattern of the normal and mutant genes in these animals is similar to that predicted for humans with RDS-mediated autosomal-dominant retinitis pigmentosa. These mice may thus be considered an animal model for this disease.
Altered States: Taxes and the Location of Foreign Direct Investment in America (1993)

This paper examines the effect of taxation on foreign investment and on business location within the United States. The idea is to compare the inter-state distribution of investments from certain foreign countries (those with foreign tax credit systems) with the distribution of investments from other countries. Investors from countries with foreign tax credit systems receive home-country tax credits for income taxes paid to US states, so they are less likely than are other investors to avoid investing in high-tax states. The results indicate that 1% differences in state corporate tax rates are associated with 7-9% differences between the investment shares of foreign tax credit investors and the investment shares of all others, suggesting that state taxes significantly influence the pattern of foreign direct investment in the US.

Postadsorptive transition in fibrinogen adsorbed to polyurethanes: Changes in antibody binding and sodium dodecy1 sulfate elutability (1992)

Residence time-dependent changes in fibrinogen after adsorption to six different polyurethanes were examined by measuring polyclonal antifibrinogen binding to the adsorbed protein. The amount of adsorbed fibrinogen that could be eluted by sodium dodecyl sulfate (SDS) was also measured. Baboon fibrinogen was first adsorbed from dilute plasma to the polymers, which were then stored in either buffer or buffered albumin solution prior to testing. Subsequently, the amount of antifibrinogen bound by the adsorbed fibrinogen was measured using a direct enzyme linked immunosorbent assay (ELISA). Alternatively, the surface with the adsorbed fibrinogen was soaked in a 3% SDS solution, and the amount of retained 125I-radiolabeled fibrinogen was measured. With increasing residence time, decreases in both antibody binding and the SDS elutability of the adsorbed fibrinogen occurred, but the rate of change was dependent on the polyurethane to which the fibrinogen was adsorbed. In addition, the antibody binding per unit of adsorbed fibrinogen, when measured immediately after the adsorption step, varied by approximately a factor of 3 among the various polyurethanes. When the protein-coated surfaces were stored in buffered albumin solution rather than buffer, the decrease in the reactivity of fibrinogen with residence time did not occur on some of the surfaces. This study shows that the chemical properties of the adsorbing surface influence the rate at which adsorbed fibrinogen undergoes change. The significance of the polymer-dependent changes in adsorbed fibrinogen with respect to blood reactions with polymers is discussed.
Handling safety improvement for steer-by-wire vehicle using fuzzy controller (2011)

In this study, a novel controller is proposed to improve vehicle handling safety. The vehicle utilizes from steer by wire technology to actively control both front wheels steering angle independently. This technology can improve vehicle maneuverability and driver comfort. The controller consists of Fuzzy PID controller plus Fuzzy compensator. Dynamic of a nonlinear 8DOF model of a vehicle is derived for Simulation purpose. Desired yaw rate is designed based on steady-state steering on the circular path. The controller feedback from yaw rate error and its time derivative, lateral acceleration, side slip angle and roll angle to improve vehicle handling safety and roll stability. Simulation results show the controller high performance in tracking desired yaw rate and simultaneously preservation of stability. Furthermore, results show amazing robustness of the controller due to model uncertainties such as vehicle longitudinal velocity, mass, location of center of mass, moment of inertia, coefficient of friction and disturbance of braking moment.
Photothermally triggered actuation of hybrid materials as a new platform for in vitro cell manipulation (2017)

Abstract Mechanical forces in the cell’s natural environment have a crucial impact on growth, differentiation and behaviour. Few areas of biology can be understood without taking into account how both individual cells and cell networks sense and transduce physical stresses. However, the field is currently held back by the limitations of the available methods to apply physiologically relevant stress profiles on cells, particularly with sub-cellular resolution, in controlled in vitro experiments. Here we report a new type of active cell culture material that allows highly localized, directional and reversible deformation of the cell growth substrate, with control at scales ranging from the entire surface to the subcellular, and response times on the order of seconds. These capabilities are not matched by any other method, and this versatile material has the potential to bridge the performance gap between the existing single cell micro-manipulation and 2D cell sheet mechanical stimulation techniques.
Dual scintillator detection method to solve PSPMT edge resolving problem (2004)

For the design of a high resolution PET detector based on PSPMTs (position-sensitive PMT), the insensitive area at the edge of the PSPMT normally prevents close packing of the scintillator crystals directly on the entire front face of the PSPMT. This edge-resolving problem is particularly severe for a high resolution PET system with multiple detector rings since it would cause gaps between detector rings and may lead to severe image artifacts. We have proposed a new method to solve this edge resolving problem by a dual scintillator detection method: it optically couples one scintillator at the insensitive edge of the PSPMT to another scintillator at the adjacent sensitive area; these two scintillators have different decay times. With this method, a gamma ray interaction that happens inside either scintillator can be detected, and the identification of which scintillator can be achieved by differentiating pulse shapes between the two scintillators. The feasibility of the method has been demonstrated with experiments measurements. Also, the artifacts from the missing data due to the gaps among detector rings has been investigated preliminarily with PET System Monte Carlo simulations.

The Role of Permutation Invariance in Linear Mode Connectivity of Neural\n Networks (2021)

In this paper, we conjecture that if the permutation invariance of neural\nnetworks is taken into account, SGD solutions will likely have no barrier in\nthe linear interpolation between them. Although it is a bold conjecture, we\nshow how extensive empirical attempts fall short of refuting it. We further\nprovide a preliminary theoretical result to support our conjecture. Our\nconjecture has implications for lottery ticket hypothesis, distributed\ntraining, and ensemble methods.\n
Macroscopic Diversity in Frequency Reuse Radio Systems (1987)

Macroscopic diversity is a technique that can facilitate high quality and ubiquitous communications between low-power portable radiotelephones and data terminals, and radio base stations (ports) that are connected to the local network. It uses radio signals from several base stations to mitigate the effect of shadow fading, a variation of signal strength over space created by the presence of buildings, foliage, and terrain variations. With a path loss exponent of four and a shadow fading standard deviation of 10 dB, four-branch macroscopic diversity results in a 13 dB improvement in signal strength and a 15 dB improvement in signal to cochannel interference ratio for high user capacity interference-limited operation. (Both figures are for 99 percent statistical coverge of the service area.) The improvement in signal to cochannel interference ratio is equivalent to a factor-of-five savings of spectrum.
Multiple Regulation of STE2 , a Mating-Type-Specific Gene of Saccharomyces cerevisiae (1986)

The Saccharomyces cerevisiae STE2 gene, which is required for pheromone response and conjugation specifically in mating-type a cells, was cloned by complementation of the ste2 mutation. Transcription of STE2 is repressed by the MAT alpha 2 gene product, so that the 1.4-kilobase STE2 RNA is detected only in a or mat alpha 2 strains, not in alpha or a/alpha cells. However, STE2 RNA levels are also increased by the mating pheromone alpha-factor and decreased in strains bearing mutations in the nonspecific STE4 gene. Regulation of STE2 expression in a cells is therefore achieved by several mechanisms.
PlanarRecon: Realtime 3D Plane Detection and Reconstruction from Posed Monocular Videos (2022)

We present PlanarRecon - a novel framework for globally coherent detection and reconstruction of 3D planes from a posed monocular video. Unlike previous works that detect planes in 2D from a single image, PlanarRecon incrementally detects planes in 3D for each video fragment, which consists of a set of key frames, from a volumetric representation of the scene using neural networks. A learning-based tracking and fusion module is designed to merge planes from previous fragments to form a coherent global plane reconstruction. Such design allows Planar-Recon to integrate observations from multiple views within each fragment and temporal information across different ones, resulting in an accurate and coherent reconstruction of the scene abstraction with low-polygonal geometry. Experiments show that the proposed approach achieves state-of-the-art performances on the ScanNet dataset while being real-time. Code is available at the project page: https://neu-vi.github.io/planarrecon/.
Working Memory Training - A Cogmed Intervention (2016)

This study of working memory training investigates the impact of intervention with memory training on students' school performance. The training consisted of 25 occasions spread over five weeks. A total of 32 students from the first grade of primary school participated in the study, with 16 students in the intervention and 16 in the control group. Before and after the intervention, all the participants were tested on word decoding skills, reading comprehension, and automated mental arithmetic. The results showed that both groups had improved on all tests after the intervention, but that the intervention group performed significantly better on the word decoding test than the control group. However, this study demonstrated no differences due to memory training with regard to mental arithmetic between the intervention group and the control group. A possible interpretation of the result is that structured memory training is beneficial for students’ reading development.
An Optimal Approach for Image Transmission in Multi-Rate Wireless Sensor Network (2007)

Many Sensor applications such as monitoring and surveillance may require image sensor array to conduct collaborative image transmissions in Wireless Sensor Network (WSN). The large size image transmission in WSN is a bottleneck due to the limited energy resources. In this paper, we propose an optimal scheme for image sensors to utilize inter-sensor correlations to decide transmission patterns based on a Multi-Rate Least Cost Path (MRLCP) routing scheme, which achieves high energy efficiencies and longer network lifetime. This optimization scheme allows each image sensor to transmit optimal fractions of the overlapped images through appropriate ratebased routing paths. A specific genetic algorithm is designed to solve such discrete optimization problem. The simulation results show that the proposed image transmission scheme can achieve considerable gains in terms of the WSN energy efficiency and network lifetime extension.
Lack of Inverse Relationship Between the Net Charge of T-Independent Immunogens and the Responding Spleen Cells (1975)

Previous studies have demonstrated an inverse relationship between the net electrical charge of immunogens and the antibodies they elicit. This correlation was found to be expressed at the cellular level. It has been shown that thymus-derived cells may recognize immunogens on the basis of their overall electrical charge. In this study, charged T-independent copolymers composed of tyrosine, glutamic acid, and lysine of the D configuration were prepared in order to find out whether this net charge phenomenon holds also for immunogens which do not require helper T cells for generation of immune response. Spleen cells were fractionated over negatively charged glass bead columns, and their immunocompetence was tested by transferring them into irradiated recipient mice which were immunized with the dinitrophenylated acidic or basic T-independent carrier. No differences in the responsiveness to the dinitrophenyl group on either carrier could be detected in recipients of unfractionated or fractionated cells on the charged columns. Similar results were obtained with the negatively charged T-independent branched polypeptide poly-(DTyr,DGlu)-poly(DPro)--poly(DLys). Filtration of spleen cells through glass bead columns did not affect the immune response potential of the recipient mice. In contrast, a significant reduction was observed in the frequency of positive responses in recipients of filtered cells, which were immunized with the negatively charged T-dependent poly(DTyr,DGlu)-poly(DPro)--poly(DLys). Thus, the inverse net charge phenomenon holds only for T-dependent antigens.
Pituitary adenylate cyclase‐activating polypeptide attenuates streptozotocin‐induced apoptotic death of RIN‐m5F cells through regulation of Bcl‐2 family protein mRNA expression (2008)

Oxidative stress, followed by the apoptotic death of pancreatic β cells, is considered to be one of causative agents in the evolution of the type 2 diabetic state; therefore, the protection of β cells can comprise an efficacious strategy for preventing type 2 diabetes. In the present study, RIN‐m5F cells (i.e. the rat insulinoma β cell line) were stimulated with streptozotocin, resulting in a time‐ and concentration‐dependent release of lactate dehydrogenase. There appeared to be significant apoptotic cell death after 2 h of treatment with streptozotocin at 10 m m , as demonstrated by terminal deoxynucleotidyl transferase‐mediated dUTP nick end‐labeling staining and 2.6‐fold activation of cellular caspase‐3, an apoptotic enzyme. By contrast, some neuropeptides of the glucagon‐secretin family and coenzyme Q 10 , an endogenous mitochondrial antioxidant, could attenuate streptozotocin cytotoxicity, and especially pituitary adenylate cyclase‐activating polypeptide (PACAP), at a concentration of 10 −7 m , exhibited 34% attenuation of lactate dehydrogenase release from streptozotocin‐treated RIN‐m5F cells. Quantitative RT‐PCR experiments indicated the inhibitory effect of PACAP on streptozotocin‐evoked up‐regulation of pro‐apoptotic factor (Noxa and Bax) and a 2.3‐fold enhancement of Bcl‐2 mRNA expression, a pro‐survival protein, was also observed after addition of PACAP. The data obtained suggest the anti‐apoptotic role of PACAP in streptozotocin‐treated RIN‐m5F cells through the regulation of pro‐apoptotic and pro‐survival factors.
Magnetization and polarization of orientationally ordered systems (1991)

It is a rare case of association of breast cancer and ileal GIST in NF1. Laparoscopic resection of intestinal GIST has shown in some studies to have oncological outcomes comparable to laparotomy. Furthermore, laparoscopy is associated with better perioperative outcomes and shorter hospital stays. Further studies with a higher level of evidence are needed.

Development of an Orbital Endoscope for Use with the Free Electron Laser (2004)

Quasi-in-situ characterization of microstructure evolution in friction stir welding of aluminum alloy (2023)

The in-situ investigation of microstructure evolution during friction stir welding (FSW) can provide very important theoretical guidance to control the microstructure and mechanical properties of the FSW joint. In this study, a quasi-in-situ investigation method of the microstructure evolution in friction stir welding of AA1050 aluminum alloy is developed. The microstructure along the material flow path was characterized and analyzed by taking the strain, strain rate, and temperature into account simultaneously. The results show that the microstructure evolution during the FSW of aluminum alloy can be divided into four stages according to the material flow state and thermal history. Firstly, grain coarsening by static recovery and static recrystallization occurs at the static preparatory stage (or called the preheating stage). Secondly, grain refining by continuous dynamic recrystallization occurs at the acceleration stage, where the temperature gradually increases to nearly a constant. The grain size is mainly controlled by the accumulative total strain. The strain rate only affects the rate of dislocation generation and the type of β-fiber simple shear texture components. Thirdly, at the high-velocity flow stage, a dynamic equilibrium between plastic deformation and dynamic recrystallization is maintained, and the grain size only fluctuates within a small range. Finally, a second grain-coarsening process occurs through normal grain growth due to thermal activation at the deceleration stage. This process is inevitable because it occurs under the cover of the tool shoulder. The grain coarsening during the normal cooling stage is avoided in this study due to the rapid cooling used, which has been widely reported by published documents.
Mechanical allodynia in rats is blocked by a Ca2+ permeable AMPA receptor antagonist (1999)

Mild thermal injury to the hindpaw induces tactile allodynia distal to the injury. The allodynia is blocked by non-NMDA, but not NMDA, antagonists. The calcium permeable subtype of non-NMDA receptors is blocked by Joro spider toxin (JSTX). We injected JSTX or saline intrathecally followed after 5 min, 6 or 24 h by thermal injury. Rats receiving saline had decreased mechanical thresholds. Rats receiving 3 μg JSTX 5 min or 6 h prior to burn showed no allodynia. JSTX had no prominent side effects at doses between 1 and 5 μg. JSTX (5 μg) had no effect on thermal threshold. These results are consistent with the hypothesis that spinal mechanisms leading to tactile allodynia in this injury model act via a calcium permeable AMPA linkage.
