RIBBING INSTABILITY IN COATING FLOWS: EFFECT OF POLYMER ADDITIVES (1982)

Data are presented which show the effect of dilute addition of polymer on the ribbing instability in coating flows. A qualitative model which treats the growth of a disturbance as an extensional flow suggests that elasticity is a destabilizing factor, in agreement with the observations.
Is there a potential role for protein‐conjugate pneumococcal vaccine in older adults? (2012)

Longstanding controversy over the efficacy of 23-valent pneumococcal polysaccharide vaccine (PPV23) led to a recommendation by the Joint Committee on Vaccination and Immunisation (JCVI) of the United Kingdom in March 2011, to discontinue routine use of PPV23 in older adults.(1) Following careful review of the evidence and feedback from stakeholders, the JCVI decided to retain the original policy of uniform vaccination of adults >65 years of age, while keeping the subject under continued review. In the United States, the Advisory Committee on Immunization Practices (ACIP) which is also concerned about the efficacy of PPV23 is currently considering a different strategy, i.e. adding 13-valent pneumococcal protein-conjugate vaccine (PCV13) for recommended use in adults, following recent Food and Drug Administration (FDA) approval for this purpose in adults over 50 years of age. It is therefore timely to review the options for prevention of pneumococcal disease in adults.
Peer-to-Peer Context Reasoning in Pervasive Computing Environments (2008)

In this paper, we propose a peer-to-peer approach to derive and obtain additional context data from low-level context data that may be spread over multiple domains in pervasive computing environments. In this system, peers are self-organized into a semantic peer- to-peer network as the underlying communication substrate. Context reasoning is done in a distributed fashion through logical reasoning according to a set of user-defined rules. Both pull and push services are supported in the system to enable message exchange during the reasoning process. We present our design concepts, and prove the effectiveness of our system through the prototype evaluation.
A Proposed Standardized Testing Procedure for Autonomous Ground Vehicles (2008)

Development of unmanned vehicles will increase as the need to save lives rises. In both military and civilian applications, humans can be taken out of the loop through the implementation of safe and intelligent autonomous vehicles. Although hardware and soft-ware development continue to play a large role in the autonomous vehicle industry, vali-dation of these systems will always be necessary. The ability to test these vehicles thor-oughly and efficiently will ensure their proper and flawless operation. On November 3, 2007 the Defense Advanced Research Projects Agency held the Ur-ban Challenge to drive the development of autonomous ground vehicles for military use. This event required vehicles built by teams across the world to autonomously navigate a 60 mile course in an urban environment in less than 6 hours. This thesis addresses the testing aspect of autonomous ground vehicles that exhibit the advanced behaviors neces-sary for operating in such an event. Specifically, the experiences of Team Victor Tango and other Urban Challenge teams are covered in detail. Testing facilities, safety measures, procedures, and validation methods utilized by these teams provide valuable information
Surgical Skill Assessment using Motor Control Features and Hidden Markov Model (2019)

Surgical Skill Assessment has increased interest through which the training and objective feedback to surgeons can be given based on the task performance. In this paper, motor control features which are a part of psychomotor learning, are developed based on the camera plane coordinates of the tip of the tools from the videos of surgeons performing the Urethro-Vesicle Anastomosis (UVA) surgical task. Classification into Novices (N) and Experts (E), when compared to the manual encoding of subject expertise based on the Dreyfus model, resulted in high accuracy. Additionally, this study could form a basis for closed loop surgical training, specifically for the novitiate surgeons.

α‐θ Brainwave Training and β‐Endorphin Levels in Alcoholics (1989)

An alpha-theta brainwave biofeedfack training program was applied as a novel treatment technique for chronic alcoholics. Following a temperature biofeedback pretraining phase, experimental subjects completed 15 30-min sessions of alpha-theta biofeedback training. Compared to a nonalcoholic control group and a traditionally treated alcoholic control group, alcoholics receiving brainwave training (BWT) showed significant increases in percentages of EEG record in alpha and theta rhythms, and increased alpha rhythm amplitudes. Alcoholics receiving BWT showed a gradual increase in alpha and theta brain rhythms across the 15 experimental sessions. These experimentally treated alcoholics showed sharp reductions in self-assessed depression (Beck's Depression Inventory) compared to the control groups. Alcoholics receiving standard medical treatment (abstinence, group psychotherapy, antidepressants) showed a significant elevation in serum beta-endorphin levels at the conclusion of the experiment. This neuropeptide is an index of stress and a stimulant of caloric (e.g., ethanol) intake. Application of brainwave treatment, a relaxation therapy, appears to counteract the increase in circulating beta-endorphin levels seen in the control group of alcoholics. 13-month follow-up data indicate sustained prevention of relapse in alcoholics that completed alpha-theta brainwave training.
Cellular proteostasis decline in human senescence (2019)

Abstract Proteostasis collapse, the diminished ability to maintain protein homeostasis, has been established as a hallmark of nematode aging. However, whether proteostasis collapse occurs in humans has remained unclear. Here we demonstrate that proteostasis decline is intrinsic to human senescence. Using transcriptome-wide characterization of gene expression, splicing and translation, we found a significant deterioration in the transcriptional activation of the heat shock response in stressed senescent cells. Furthermore, phosphorylated HSF1 nuclear localization and distribution were impaired in senescence. Interestingly, alternative splicing regulation was also dampened. Surprisingly, we found a decoupling between different Unfolded Protein Response (UPR) branches in stressed senescent cells. While young cells initiated UPR-related translational and transcriptional regulatory responses, senescent cells showed enhanced translational regulation and ER stress sensing, however they were unable to trigger UPR-related transcriptional responses. This was accompanied by diminished ATF6 nuclear localization in stressed senescent cells. Finally, we revealed a deterioration of proteasome function in senescence following heat stress, which did not recover upon return to normal temperature. Together, our data unraveled a deterioration in the ability to mount dynamic stress transcriptional programs upon human senescence with broad implications on proteostasis control, and connected proteostasis decline to human aging. Significance Protein homeostasis (proteostasis), the balance between protein synthesis, folding, and degradation, is thought to deteriorate with age, and the prevalence of protein misfolding diseases, e.g. Alzheimer’s, Parkinson’s etc., with human aging is increased. However, while in worms this phenomenon has been well established, in humans it remained unclear. Here we show that proteostasis is declined in human senescence, i.e. cellular aging. We found that while stress sensing is enhanced in senescent cells, and their response at the level of protein synthesis is intact, they fail to properly activate multiple programs required for stress adaptation at the level of gene transcription. Our findings support the notion that proteostasis decline may have major implications on human aging.
TONOMETRY (1920)

Further experiments were undertaken with a rubber bag having the size and shape of an eye, and fitted above with a ring to carry the membrane ordinarily used on the drum. At low water-pressures the difference between the deflection for open and closed connections was very small; at higher pressure and with larger weights it was nil. See Table VI. If graphs are constructed from Table The graph of the closed rubber tube will lie considerably lower, and finally the graph of the closed drum will be the lowest of all.
A 4-Channel 1.25–10.3 Gb/s Backplane Transceiver Macro With 35 dB Equalizer and Sign-Based Zero-Forcing Adaptive Control (2009)

A 4-channel 1.25-10.3 Gb/s backplane transceiver macro with an adaptive analog linear equalizer (LE) and 1-tap speculative decision-feedback equalizer (DFE) receiver (Rx) and a 3-tap pre-emphasis transmitter (Tx) is presented. The equalizers cancel 15.7-35.8 dB loss at the half-rate frequency for 10.3 Gb/s transmission over 5-75 cm FR4 backplane with fixed Tx parameters. Rx equalizer parameters are adapted by sign-based zero-forcing (S-ZF), which is applicable to any LE circuit and implemented in simple logic. The adaptive control circuit has a pattern-tolerant feature which prevents the adapted equalizer parameters from drifting for non-random data. The macro is fabricated in 90 nm CMOS technology. A Tx/Rx pair occupies 0.380 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> and consumes 260 mW from 1.2 V at 10.3 Gb/s per channel.
Surface CD107a/LAMP-1 protects natural killer cells from degranulation-associated damage (2013)

Cytotoxic lymphocytes are important for immune responses against viral infections and cancer. They are able to kill target cells through the release of cytotoxic granules (CGs) without being harmed in the process. Because the lysosomal-associated membrane proteins (LAMPs) appear on the cell surface after CG exocytosis, we hypothesized that some of these proteins might be involved in transiently protecting cytotoxic lymphocytes from self-destruction. Intracellular expression of CD107a/LAMP-1, and to a lesser extent that of CD107b/LAMP-2, correlated with lymphocyte CG content. Engineered surface expression of CD107a/LAMP-1, but not of CD107b/LAMP-2, reduced the granule-mediated killing of transfected target cells. This was dependent on glycosylation of the CD107a/LAMP-1 hinge. Moreover, surface expression of CD107a/LAMP-1 reduced binding of perforin to cells. Importantly, knockdown of CD107a/LAMP-1 in primary human natural killer (NK) cells and deficiency of CD107a/LAMP-1 in mice resulted in increased NK cell apoptosis upon target cell-induced degranulation. Thus, our data support a novel role of CD107a/LAMP-1 in the protection of NK cells from degranulation-associated suicide, which may represent a general mechanism to transiently limit self-destruction by cytotoxic lymphocytes upon target cell killing.

Colloquium: Disclination loops, point defects, and all that in nematic liquid crystals (2012)

The homotopy theory of topological defects is a powerful tool for organizing and unifying many ideas across a broad range of physical systems. Recently, experimental progress was made in controlling and measuring colloidal inclusions in liquid crystalline phases. The topological structure of these systems is quite rich but, at the same time, subtle. Motivated by experiment and the power of topological reasoning, the classification of defects in uniaxial nematic liquid crystals was reviewed and expounded upon. Particular attention was paid to the ambiguities that arise in these systems, which have no counterpart in the much-storied $XY$ model or the Heisenberg ferromagnet.
Compensation effect and volcano curve in toluene hydrogenation catalyzed by transition metal sulfides (2010)

Within the framework of volcano curves, a kinetic study of toluene hydrogenation catalyzed by transition metal sulfides highlights the variation of the apparent kinetic parameters as a function of the ab initio sulfur-metal bond energy descriptor and sulfo-reductive reaction conditions.
Detoxification of industrial wastewaters in an Extractive Membrane Bioreactor (1996)

Point source treatment of aqueous wastes produced in the chemical industry and containing toxic organic compounds in an Extractive Membrane Bioreactor (EMB) is reported. The EMB is shown to be effective in removing a range of toxic organic compounds, achieving over 99% removal at wastewater-reactor contact times of less than 30 minutes. A model which predicts the removal efficiency is discussed, and a new, advanced EMB system is described which overcomes the mass transfer limitations in the original plug flow configuration. Finally, data showing the effect of the membrane attached biofilms on membrane mass transfer is used to illustrate one of the key problems that must be solved during technology transfer if the EMB process is to prove successful at industrial scale.
Linear viscoelastic and morphological description of multiphase systems affected by processing parameters (2010)

Abstract Influence of processing methods, in terms of comparing compression and injection moldings, on the rheological behavior of polycarbonate (PC)/acrylonitrile‐butadiene‐styrene (ABS) blends and PC/ABS/glass fibers composites is presented. Blend compositions and fiber content are considered as material variables. For blends, the effect of the processing route on the viscoelastic functions is evident only for low shearing frequencies. Injection molding created morphology with cocontinuous character, while compression molded blends have “relaxed” structure, where dispersed phase domains are several times larger than in injection molded ones. The glass fiber reinforcement led to the significant differences in viscoelastic properties of composites processed by injection and compression molding. Injected composites have both moduli always higher than compression molded. Also, fiber lengths are reduced more for compressing molding. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2011
Purification and Properties of a Golgi-Derived (.alpha.1,2)-Mannosidase-I from Baculovirus-Infected Lepidopteran Insect Cells (IPLB-SF21AE) with Preferential Activity toward Mannose6-N-Acetylglucosamine2 (1995)

Because the availability and subcellular distribution of processing mannosidases in cells play such powerful roles in determining ultimate structures of glycoconjugates, we desired to identify, characterize, and investigate possible regulation of mannosidases in infected and noninfected lepidopteran insect cells. Since our previous observations that a mannosidase activity that converted Man6GlcNAc2 to Man5GlcNAc2 was enhanced in virus-infected cells, thus providing the necessary intermediate for further processing to complex-type oligosaccharides, we attempted purification of this enzyme. A mannosidase was isolated and purified from membranes, operationally defined as Golgi, of recombinant baculovirus-infected Spodoptera frugiperda (IPLB-SF-21AE) cells. The molecular mass of this protein was approximately 63 kDa. Assays performed by measuring the conversion of NaB3H4-reduced Man6GlcNAc2-ol to Man5GlcNAc-[3H]GlcNAc2-ol demonstrated that the mannosidase activity was dependent on the presence of divalent cations, which was optimal for Ca2+ at pH 6.0. Inclusion of 1-deoxymannojirimycin resulted in 50% inhibition at a concentration of 20 microM, whereas swainsonine did not show such inhibition. No activity was observed with p-nitrophenyl alpha-D-mannoside (4 mM) as a substrate. The preferred reduced oligosaccharide substrate was Man6GlcNAc2-ol, with lower activities obtained with Man9GlcNAc2-ol, Man8GlcNAc2-ol, and Man7GlcNAc2-ol. With Man6GlcNAc2-ol as substrate, products smaller than reduced Man5GlcNAc2-ol were not observed. Mannose was also liberated from the glycoprotein, ovalbumin. These properties are consistent with an enzyme classification as a type I (alpha 1,2)-Man6-mannosidase.

Analysis of optical and acoustic emissions during CO2 laser welding of a stainless steel (1997)

We have measured optical and acoustic emissions from a CO2 laser welding of 304 stainless steel to monitor the welding process. The optical emission of Fe atom was detected by a spectrometer with an optical fiber. The acoustic emission was collected by a microphone. The bead on plate welding was performed with a 5 kW CO2 laser with a 245 mm parabolic mirror and its power was changed from 2 to 5 kW. Amplitude of both the optical and the acoustic emissions fluctuated quickly. There were some peaks in fast Fourier transform (FFT) power spectra of the signals. The major peaks of the acoustic emission appeared around 2.8 kHz when the welding was keyhole-type. When the welding was heat conduction-type, the frequency peaks above 5 kHz in the acoustic emission became larger in comparison to that around 2.8 kHz. The frequency distribution of the acoustic emission changed corresponding to the welding types. Similar dependency of the frequency spectrum on the welding types was observed in the optical signal. This correlation is reproducible and would be useful for online monitoring and process control.
Intensity-dependent absorption and photorefractive properties in cerium-doped BaTiO3 crystals (1995)

We report the optical absorption and photorefractive properties of a series of cerium-doped barium titanate crystals. The light-induced absorption and the intensity-dependent two-beam coupling gain coefficient indicate that there are at least two active trap levels in cerium-doped BaTiO3 crystals. The total effective trap density, the Debye screening wave vector, and the intensity-dependent factor increase with cerium-doping concentration as well as the pump beam intensity. The positive light-induced absorption and the negative absorption gain coefficient as the grating wave vector approaches zero indicate that the excitation cross section of shallow traps is larger than that of deep traps. One of these crystals exhibits a two-beam coupling coefficient of 8.06 cm−1 for ordinarily polarized beams, which is the highest ever reported to date. Both electro-optic index grating and absorption grating are contributing to the coupling coefficient. The response time of as-grown cerium-doped BaTiO3 with 15 ppm cerium is 220 ms at an intensity of 800 mW/cm2.
