Characterization and mechanical support of asymmetric hydrogel membranes based on the interfacial cross-linking of poly(vinyl alcohol) with toluene diisocyanate (1996)

Asymmetric membranes based on the interfacial cross-linking of poly(vinyl alcohol) hydrogels with toluene diisocyanate exhibit enhanced size selectivity for binary protein separations with minimal reductions in the flux of the smaller protein. The asymmetric nature of the hydrogel prevents the use of swelling measurements to characterize the mesh size of the selective surface layer. Alternatively, the permeability coefficient of the surface layer and the contribution of this layer to the overall resistance were estimated. A direct relationship was found between the surface layer permeability coefficient and the amount of urea/urethane groups, determined from infrared spectroscopy, introduced into the surface during interfacial cross-linking. Impregnation of the hydrogel within the pores of a microfiltration membrane for mechanical support was demonstrated and the transport properties of this composite membrane compared well to those of an unsupported hydrogel.
S9A-06 SESSION 9A: CRANIOPLASTY A NEW WINDOW OF OPPORTUNITY FOR NEUROSURGEONS: TRANS-CRANIOPLASTY ULTRASOUND (TCU) THROUGH SONOLUCENT CRANIAL IMPLANTS (2019)

Introduction: Previously, sonographic evaluation of the intracranial contents has been limited to either intraoperative use following bone flap removal or in neonates with open fontanelles, secondary to the impedance of cranial bone. Therefore, we hypothesized that cranial bone replacement (i.e. cranioplasty) with sonolucent implants may represent a “window into the brain” by allowing trans-cranioplasty ultrasound (TCU) to serve as a novel bedside imaging modality.To examine the potential sonolucency of commonly-used cranial implants made of various biomaterials and to evaluate this imaging modality in a live human patient requiring cranioplasty reconstruction. Methods: A three-phase study was comprised of 1) cadaveric evaluation of trans-cranioplasty ultrasound (TCU) with various cranioplasty implants of varying materials, 2) intraoperative TCU during right-sided cranioplasty with clear implant made of poly-methyl-methacrylate (PMMA), and 3) bedside TCU on postoperative day 5 after cranioplasty. Results: TCU through clear PMMA, polyether-ether-ketone (PEEK), and opaque PMMA cranial implants revealed implant sonoluceny, in contrast to autologous bone and porous-polyethylene. In a live human patient, intraoperative ultrasound via the clear PMMA implant revealed recognizable ventricular anatomy. Furthermore, postoperative bedside ultrasound revealed comparable ventricular anatomy and a small epidural fluid collection corresponding to that visualized on an axial computed tomography (CT) scan. Conclusion: Sonolucent cranial implants, such as those made of clear PMMA, hold great promise for enhanced diagnostic and therapeutic applications previously limited by cranial bone. Furthermore, as functional cranial implants are manufactured with implantable devices housed within clear PMMA, the possibility of utilizing ultrasound for real-time surveillance of intracranial pathology becomes much more feasible.

Highly accurate texture-based vehicle segmentation method (2004)

In modern traffic surveillance, computer vision methods have often been employed to detect vehicles of interest because of the rich information content contained in an image. Segmentation of moving vehicles using image processing and analysis algorithms has been an important research topic in the past decade. However, segmentation results are strongly affected by two issues: moving cast shadows and reflective regions, both of which reduce accuracy and require postprocessing to alleviate the degradation. We propose an efficient and highly accurate texture-based method for extracting the boundary of vehicles from the stationary background that is free from the effect of moving cast shadows and reflective regions. The segmentation method utilizes the differences in textural property between the road, vehicle cast shadow, reflection on the vehicle, and the vehicle itself, rather than just the intensity differences between them. By further combining the luminance and chrominance properties into an OR map, a number of foreground vehicle masks are constructed through a series of morphological operations, where each mask describes the outline of a moving vehicle. The proposed method has been tested on real-world traffic image sequences and achieved an average error rate of 3.44% for 50 tested vehicle images. © 2004 Society of Photo-Optical Instrumentation Engineers.
Development of Multifunction Machine by Wire Feeding Device (2008)

In recent years, advances in technology have enabled the machining of nonconductive materials by electrical discharge machining (EDM). However, some machining characteristics still need to be improved for the wide industrial application of EDM. Among them are (i) surface roughness that is not good enough for finish machining, and (ii) the existence of a residual conductive layer on a material' s surface after machining that often requires a secondary process, that is, either shot peening or heat disposal process, for removal. In this research, in order to simplify the process for rough machining and finish machining, we designed a multifunctional machine that uses a feed wire as a tool for the forming process by wire EDM on the same machine, to ensure machining accuracy since the workpiece is not removed from the initial setup. The experimental setup includes a movable pulley with two wire guides at the center (WEDG), which is useful for the final finish processing without wire vibration. The Si3N4 material used as a workpiece was subjected to form machining, surface layer machining and abrasive machining before finish machining. We obtained a mirror surface using a wire with diamond particles as a tool.
Modeling IPMC for Design of Actuation Mechanisms (2010)

Ionic polymer metallic composite (IPMC, which is also known as ICPF) [Oguro et al., 1992; Shahinpoor et al., 1999a] is one of the electroactive polymers that have shown potential for practical applications. This material was described in detail in Chapter 6, and the focus of the present chapter is on the modeling aspects of electroactivation, providing a foundation for the design of actuation mechanisms. IPMC is an electroless plated electroactive polymer (EAP) material that bends when subjected to a voltage across its thickness.
Photobacterium arenosum WH24, Isolated from the Gill of Pacific Oyster Crassostrea gigas from the North Sea of Germany: Co-cultivation and Prediction of Virulence (2022)

Cream colored bacteria from marine agar, strain WH24, WH77, and WH80 were isolated from the gill of the Crassostrea gigas a Pacific oyster with a filter-feeding habit that compels accompanying bacteria to demonstrate a high metabolic capacity, has proven able to colonize locations with changing circumstances. Based on the 16S rRNA gene sequence, all strains had high similarity to Photobacterium arenosum CAU 1568<sup>T</sup> (99.72%). This study involved phenotypic traits, phylogenetic analysis, antimicrobial activity evaluation, genome mining, Co-cultivation experiments, and chemical studies of crude extracts using HPLC and LC-HRESIMS. Photobacterium arenosum WH24 and Zooshikella harenae WH53<sup>T</sup>were co-cultivated for 3 days in a rotary shaker at 160 rpm at 30 °C, and LC-MS monitored the chemical profiles of the co-cultures on the third day. The UV chromatograms of the extracts of the co-cultivation experiments show that Zooshikella harenae WH53<sup>T</sup> could be inhibited by strain WH24. The high virulence of Photobacterium arenosum WH24 was confirmed by genome analysis. Gene groups with high virulence potential were detected: tssA (ImpA), tssB (ImpB/vipA), tssC (ImpC/vipB), tssE, tssF (ImpG/vasA), tssG (ImpH/vasB), tssM (IcmF/vasK), tssJ (vasD), tssK (ImpJ/vasE), tssL (ImpK/vasF), clpV (tssH), vasH, hcp, lapP, plpD, and tpsB family.
Soft route for monodisperse gold nanoparticles confined within SH-functionalized walls of mesoporous silica (2009)

In this paper, we report a soft route leading to small gold nanoparticles confined within the framework of 2D-hexagonal mesoporous SH-functionalised silicas. For that purpose, a hydrophilic bis-silylated precursor containing a disulfide unit was prepared. Framework-functionalised materials were obtained in one step by the “direct synthesis” method which consists of a co-hydrolysis and polycondensation of a bridged organosilica precursor with tetraethylorthosilicate (TEOS) in the presence of a non-ionic triblock co-polymer (P123) as structure-directing agent. Reduction of SS groups leads quantitatively to SH functional groups within the framework of 2D hexagonal mesoporous silicas. All these materials have been characterised by TEM, 13C and 29Si NMR experiments, nitrogen gas adsorption, powder XRD and elemental analysis. The subsequent growth of monodisperse gold nanoparticles of small size (∼2 nm) within the walls of mesoporous materials was studied and is discussed.
An improved inverse kinematics solution of 6R-DOF robot manipulators with euclidean wrist using dual quaternions (2016)

The present work focuses on the development of a methodology that can be used to solve the inverse kinematics of 6R robot manipulators with Euclidean wrist. Dual quaternions are used as screw motion operators to perform line transformations to the joint axes. The transformations are performed after each joint angle is found. This process accommodates the robot pose on each step from the initial pose to the final pose when all the joint angles have been found. In each step, the appropriate sub problems of Paden-Kahan are used to find the joint angles. The main contribution of the presented methodology is that it is a more general solution than previous approaches. Additionally, an extension of the second sub problem of Paden-Kahan is derived for parallel axes. The proposed algorithm can be used to solve the inverse kinematics problem of most of the 6R robot manipulator configurations, with or without shoulder offset, and with or without intersecting axes of the first and second joint.
STRUCTURAL EVALUATION OF A DIBENZOBICYCLIC PHOSPHORANE. ANOTHER EXAMPLE OF A BERRY EXCHANGE COORDINATE (1990)

Abstract The single crystal X-ray diffraction study and the structural evaluation of l-phenyl-5-aza-2,8-dioxa-lphospha(V)-dibenzo[c,f]bicyclo[3,3,0]octane, 1 show that the compound lies on the Berry coordinate approximately 50% between a trigonal bipyramid with the oxygen atoms in axial positions and a rectangular pyramid.
Development of luminescent solar concentrators : molecular alignment chips (2014)

The project aims to develop methods for the synthesis of arrays of silica nanochannels with disc-shaped morphology and tunable pore size. These so-called Molecular Alignment Chips (MACs) are promising host materials for the supramolecular organization of guests. The project investigates several applications of MACs with a focus on light-harvesting systems such as luminescent solar concentrators (LSCs). The fundamental project objectives concern the synthesis of MACs with well-defined particle morphology and tunable nanochannel diameter. Host materials of this kind provide a platform for the alignment of any desired guest species. In the field of LSCs, this ultimately opens possibilities for increasing the trapping efficiency and for reducing self-absorption losses.
Study on Mediating Role of Trust in the Relationship between Organizational Citizenship Behavior and Organizational Justice in Service Organizations (Case Study of Welfare Organization of Alborz Province) (2013)

In today organizations, preparing for future changes exerts intense pressures on employees to take responsibility for their job enhancement planning, education and compensation. Also organizations such as welfare ones are willing and trying to select employees who exceed their tasks and job description so that their organizations can meet their needs, satisfy clients and adapt with changing nature of the society. Present paper aims to study mediating variable of trust with regard to the relationship between organizational justice and organizational citizenship behavior. Present research is a descriptive-applied one. Data were collected from interviews and questionnaires. Statistical population consisted of all employees of welfare organization of Alborz province and judgment sampling method was employed. To verify reliability, internal consistency was tested with Cronbach alpha. To verify the hypotheses, structural equation model was used. In total, using Lisrel software two measurement and structural models were exploited for factor analysis, path analysis and model fitness. Research findings showed that there was a significant relationship between all research variables (organizational justice dimensions, organizational justice, trust and organizational citizenship behavior). Finally it was seen that in welfare organization of Alborz Province there was a very significant relationship between employees' trust and their perception of organizational justice (98) and this suggests importance of this variable as a mediator in welfare organization.
Association of Animal and Plant Protein Intake With All-Cause and Cause-Specific Mortality (2016)

High animal protein intake was positively associated with cardiovascular mortality and high plant protein intake was inversely associated with all-cause and cardiovascular mortality, especially among individuals with at least 1 lifestyle risk factor. Substitution of plant protein for animal protein, especially that from processed red meat, was associated with lower mortality, suggesting the importance of protein source.
Mechanical Stress Evaluation of Si Metal–Oxide–Semiconductor Field-Effect Transistor Structure Using Polarized Ultraviolet Raman Spectroscopy Measurements and Calibrated Technology-Computer-Aided-Design Simulations (2011)

The mechanical stresses in Si metal–oxide–semiconductor field-effect transistors (MOSFETs) were evaluated by polarized UV Raman spectroscopy measurements and stress simulations. To calibrate stress parameters of the materials used in the Si MOSFETs, we compared measured and simulated Raman frequency shifts on the cleaved Si(110) surfaces of the MOSFETs. Consequently, we extracted intrinsic stress values of -400 MPa for a SiO 2 , -200 MPa for polycrystalline Si (poly-Si), 700 MPa for Ni silicide, 1250 MPa for a SiN tensile stress liner, and -3500 MPa for a SiN compressive stress liner by finding good agreement between the measured and simulated Raman shift distributions. To verify our stress simulation, we investigated the source/drain width dependences of Raman frequency shifts near the channel regions of Si MOSFETs by top-view Raman measurements. The calculated Raman frequency shifts agreed well with the results of polarized Raman measurements in terms of not only relative tendencies but also absolute Raman shift values.
Reversible changes in heterogeneous factors in branched-chain processes (1983)

On the basis of a collection of experimental data, it has been shown that, during the course of and under the influence of chain reactions, reversible changes occur in the state of the surface and the heterogeneous stages which in turn strongly affect the kinetics and the characteristics of chain combustion as a whole.
Caspase-2 deficiency enhances whole-body carbohydrate utilisation and prevents high-fat diet-induced obesity (2017)

Caspase-2 has been shown to be involved in metabolic homeostasis. Here, we show that caspase-2 deficiency alters basal energy metabolism by shifting the balance in fuel choice from fatty acid to carbohydrate usage. At 4 weeks of age, whole-body carbohydrate utilisation was increased in Casp2<sup>-/-</sup> mice and was maintained into adulthood. By 17 weeks of age, Casp2<sup>-/-</sup> mice had reduced white adipose mass, smaller white adipocytes decreased fasting blood glucose and plasma triglycerides but maintained normal insulin levels. When placed on a 12-week high-fat diet (HFD), Casp2<sup>-/-</sup> mice resisted the development of obesity, fatty liver, hyperinsulinemia and insulin resistance. In addition, HFD-fed Casp2<sup>-/-</sup> mice had reduced white adipocyte hypertrophy, apoptosis and expansion of both subcutaneous and visceral adipose depots. Increased expression of UCP1 and the maintenance of adiponectin levels in white adipose tissue of HFD-fed Casp2<sup>-/-</sup> mice indicated increased browning and adipocyte hyperplasia. We found that while the preference for whole-body carbohydrate utilisation was maintained, HFD-fed Casp2<sup>-/-</sup> mice were not impaired in their ability to switch to utilising fats as a fuel source. Our findings suggest that caspase-2 impacts basal energy metabolism by regulating adipocyte biology and fat expansion, most likely via a non-apoptotic function. Furthermore, we show that caspase-2 deficiency shifts the balance in fuel choice towards increased carbohydrate utilisation and propose that this is due to mild energy stress. As a consequence, Casp2<sup>-/-</sup> mice show an adaptive remodelling of adipose tissue that protects from HFD-induced obesity and improves glucose homeostasis while paradoxically increasing their susceptibility to oxidative stress induced damage and premature ageing.
Efficient synchronization primitives for large-scale cache-coherent multiprocessors (1989)

This paper proposes a set of efficient primitives for process synchronization in multiprocessors. The only assumptions made in developing the set of primitives are that hardware combining is not implemented in the inter-connect, and (in one case) that the interconnect supports broadcast. The primitives make use of synchronization bits (syncbits) to provide a simple mechanism for mutual exclusion. The proposed implementation of the primitives includes efficient ( i.e. local) busy-waiting for syncbits. In addition, a hardware-supported mechanism for maintaining a first-come first-serve queue of requests for a syncbit is proposed. This queueing mechanism allows for a very efficient implementation of, as well as fair access to, binary semaphores. We also propose to implement Fetch and Add with combining in software rather than hardware. This allows an architecture to scale to a large number of processors while avoiding the cost of hardware combining. Scenarios for common synchronization events such as work queues and barriers are presented to demonstrate the generality and ease of use of the proposed primitives. The efficient implementation of the primitives is simpler if the multiprocessor has a hardware cache-consistency protocol. To illustrate this point, we outline how the primitives would be implemented in the Multicube multiprocessor [GoWo88].
A homeobox gene, PRESSED FLOWER , regulates lateral axis-dependent development of Arabidopsis flowers (2001)

It is postulated that the symmetric organization of plant lateral organs is based on two crossed axes, the abaxial-adaxial and the lateral axes. The PRESSED FLOWER (PRS) gene, the expression and function of which are dependent on the lateral axis, is reported in this study. In the prs mutant, growth of the lateral sepals is repressed, and although the size and shape of the abaxial and adaxial sepals are normal, the cell files at the lateral margins are missing. Double-mutant analyses showed that the PRS gene functions independently of the determinations of both floral organ identity and floral meristem size. The PRS gene, encoding a putative transcriptional factor with a homeodomain, was shown to be required for cell proliferation. PRS gene expression is spatially and temporally unique and is expressed in a restricted number of L1 cells at the lateral regions of flower primordia, floral organ primordia, and young leaf primordia. Our study strongly suggests that the PRS gene is involved in the molecular mechanism of lateral axis-dependent development of lateral organs in Arabidopsis.
Advanced three-dimensional television system technologies (2003)

We describe the goals of the ATTEST project, which started in March 2002 as part of the Information Society Technologies (IST) programme, sponsored by the European Commission. In the 2-year project, several industrial and academic partners cooperate towards a flexible, 2D-compatible and commercially feasible 3D-TV system-for broadcast environments. An entire 3D-video chain will be developed. We discuss the goals for content creation, coding, transmission, display and the central role that human 3D perception research will play in optimizing the entire chain. The goals include the development of a new 3D camera, algorithms to convert existing 2D-video material into 3D, a 2D-compatible coding and transmission scheme for 3D video using MPEG-2/4/7, and two new autostereoscopic displays. With the combination of industrial and academic partners and the technological progress obtained from earlier 3D projects, we expect to achieve the ATTEST goal of developing the first commercially feasible European 3D-TV broadcast system.
A real-time golf-swing training system using sonification and sound image localization (2018)

There are real-time training systems to learn the correct golf swing form by providing visual feedback to the users. However, real-time visual feedback requires the users to see the display during their motion that leads to the wrong posture. This paper proposed a real-time golf-swing training system using sonification and sound image localization. The system provides real-time audio feedback based on the difference between the pre-recorded model data and real-time user data, which consists of the roll, pitch, and yaw angles of a golf club shaft. The system also used sound image localization so that the user can hear the audio feedback from the direction of the club head. The user can recognize the current posture of the club without moving their gaze.
