Transitions between Discrete and Rhythmic Primitives in a Unimanual Task (2013)

Given the vast complexity of human actions and interactions with objects, we proposed that control of sensorimotor behavior may utilize dynamic primitives. However, greater computational simplicity may come at the cost of reduced versatility. Evidence for primitives may be garnered by revealing such limitations. This study tested subjects performing a sequence of progressively faster discrete movements, in order to stress the system. We hypothesized that the increasing pace would elicit a transition to rhythmic movements, assumed to be computationally and neurally more efficient. Abrupt transitions between the two types of movements would support the hypothesis that rhythmic and discrete movements are distinct primitives. Ten subjects performed planar point-to-point arm movements paced by a metronome: Starting at 2s the metronome intervals decreased by 36ms per cycle to 200ms, stayed at 200ms for several cycles, then increased by similar increments. Instructions emphasized to insert explicit stops between each movement with a duration that equaled the movement time. The experiment was performed with eyes open and closed, and with short and long metronome sounds, the latter explicitly specifying the dwell duration. Results showed that subjects matched instructed movement times but did not preserve the dwell times. Rather, they progressively reduced dwell time to zero, transitioning to continuous rhythmic movements before movement times reached their minimum. The acceleration profiles showed an abrupt change between discrete and rhythmic profiles. The loss of dwell time occurred earlier with long auditory specification, when subjects also showed evidence of predictive control. While evidence for hysteresis was weak, taken together, the results clearly indicated a transition between discrete and rhythmic movements, supporting the proposal that representation is based on primitives rather than on veridical internal models.
Seven novel mutations in the ORNT1 gene (SLC25A15) in patients with hyperornithinemia, hyperammonemia, and homocitrullinuria syndrome (2001)

Eight unrelated Italian patients with the hyperornithinemia, hyperammonemia, and homocitrullinuria (HHH) syndrome were analyzed for mutations in the ORNT1 gene. Seven novel mutations were identified (Q89X, G27R, G190D, R275Q, c.861insG, c.164insA, and IVS5+1G-->A). Other previously described variants were a heterozygous deletion of a phenylalanine residue (F188del) in one allele and the R179X in two. The G27R mutation was carried by two patients. Analyses of ORNT1 mRNA in four patients showed that mutant alleles were stable and of the predicted size. The current study expands the spectrum of mutations in ORNT1 gene.
Repeated Neonatal Propofol Administration Induces Sex-Dependent Long-Term Impairments on Spatial and Recognition Memory in Rats (2015)

Propofol is an anesthetic agent that gained wide use because of its fast induction of anesthesia and rapid recovery post-anesthesia. However, previous studies have reported immediate neurodegeneration and long-term impairment in spatial learning and memory from repeated neonatal propofol administration in animals. Yet, none of those studies has explored the sex-specific long-term physical changes and behavioral alterations such as social (sociability and social preference), emotional (anxiety), and other cognitive functions (spatial working, recognition, and avoidance memory) after neonatal propofol treatment. Seven-day-old Wistar-Kyoto (WKY) rats underwent repeated daily intraperitoneal injections of propofol or normal saline for 7 days. Starting fourth week of age and onwards, rats were subjected to behavior tests including open-field, elevated-plus-maze, Y-maze, 3-chamber social interaction, novel-object-recognition, passive-avoidance, and rotarod. Rats were sacrificed at 9 weeks and hippocampal protein expressions were analyzed by Western blot. Results revealed long-term body weight gain alterations in the growing rats and sex-specific impairments in spatial (female) and recognition (male) learning and memory paradigms. A markedly decreased expression of hippocampal NMDA receptor GluN1 subunit in female- and increased expression of AMPA GluR1 subunit protein expression in male rats were also found. Other aspects of behaviors such as locomotor activity and coordination, anxiety, sociability, social preference and avoidance learning and memory were not generally affected. These results suggest that neonatal repeated propofol administration disrupts normal growth and some aspects of neurodevelopment in rats in a sex-specific manner.
The LOBI Integral System Test Facility Experimental Programme (2011)

The LOBI project has been carried out in the framework of the European Commission Reactor Safety Research Programme in close collaboration with institutional and/or industrial research organizations of EC member countries. The primary objective of the research programme was the generation of an experimental data base for the assessment of the predictive capabilities of thermal-hydraulic system codes used in pressurised water reactor safety analysis. Within this context, experiments have been conducted in the LOBI integral system test facility designed, constructed, and operated (1979–1991) at the Ispra Site of the Joint Research Centre. This paper provides a historical perspective and summarizes major achievements of the research programme which has represented an effective approach to international collaboration in the field of reactor safety research and development. Emphasis is also placed on knowledge management aspects of the acquired experimental data base and on related online open access/retrieval user functionalities.

Piezoelectric‐controlled tuning capacitor for surface coils (1989)

The design of a piezoelectric-controlled trimmer capacitor and its use as a tuning element of an MRI surface coil at 63.8 MHz are described. It is found that image quality does not depend strongly on match of the coil to the transmission line but that tuning can be a significant factor. The work is intended to lead eventually to an automatic frequency control circuit in which the capacitor serves as the active element in holding the resonant frequency of the nuclei and the resonant frequency of the coil in coincidence.
CO2 refixation characteristics of developing canola seeds and silique wall (1998)

The potential for developing canola ( Brassica napus L.) seeds and the interior silique (pod) wall to refix respired CO2 has been investigated. From ribulose-1,5-bisphosphate carboxylase–oxygenase (Rubisco) and phospho enol pyruvate carboxylase (PEPC) activities, seeds were estimated to have a greater CO2 fixation capacity than silique wall endocarp during oil filling. The major component of seed fixation capacity was embryo Rubisco, which had a total activity of 6.3 nmol min-1 embryo-1 (3.7 µmol min-1 mg chlorophyll-1) at 28 days after anthesis (DAA) with smaller contributions from seed coat and embryo PEPC. Rubisco activities were probably maximal in vivo because of high silique cavity CO2 concentrations (0.8 to 2.5%). Seed chlorophyll content rapidly increased over 10-fold from 20 to 30 DAA and, with 20% of incident light transmitted through the silique wall, embryos demonstrated appreciable photosynthetic electron transport rates and most energy produced appeared to be used for Rubisco-catalysed CO2 fixation. Endocarp refixation capacity was less than seeds because chlorophyll content was not enriched and PEPC activities were relatively small. These data indicate that developing seeds and also endocarp refix respired CO2 and that embryo chlorophyll plays a critical role in this refixation.
Intraoperative electrical stimulation for functional posterior rhizotomy. (1988)

Intraoperative electrical stimulation of dorsal spinal roots from L1 to S1 bilaterally was performed in 80 patients affected by cerebral palsy, in whom spasticity was the main symptom. Clinical examination and EMG recordings showed three main features of reflex responses. We know that they indicate respectively a normal presence, a defect or an excess of inhibitory activity within the spinal circuits examined. Only those roots or rootlets involved in circuits where normal inhibitory processes are reduced or absent are surgically sectioned. Therefore these circuits are interrupted. The theoretical bases and long-term results indicate that this method is a useful and correct approach to the neurosurgical therapy of spasticity. It allows us to utilize a new important criterion to identify the roots or rootlets to be sectioned, based not on the anatomic, but on the functional selection.

Vertical handover between WiFi and UMTS networks: experimental performance analysis (2011)

In this paper, we analyze the performance of vertical handover (VHO) algorithms for seamless mobility between WiFi and UMTS networks. We focus on a no-coupling scenario, characterized by the lack of any form of cooperation between the involved players (users and network operators). In this “hostile” scenario, the VHO operations are completely operated by the mobile terminal (MT), and the network authentication procedures are unoptimized, leading to typically long handover times. In this context, we first propose a low-complexity Received Signal Strength Indicator (RSSI)-based algorithm and, then, an improved hybrid RSSI/goodput version. &#13;\nWe present experimental results based on the implementation of a real testbed with commercial WiFi (Guglielmo) and UMTS (Telecom Italia) Italian deployed networks. Despite the relatively long handover times experienced in our testbed, the proposed RSSI-based VHO algorithm guarantees an effective goodput increase at the MTs. Moreover, this algorithm mitigates the ping-pong phenomenon. Our results show that, by using simple MT-driven VHO mechanisms, the users can benefit from redundant and heterogeneous wireless network infrastructures. This can be done by leveraging on pre-existing commercially deployed networks, without the need for any modification of them.
Functional Analysis of Mmd2 and Related PAQR Genes During Sex Determination in Mice (2022)

These results may reflect functional redundancy among PAQR factors, or their dispensability in gonadal development. Our findings highlight the difficulties involved in identifying genes with a functional role in sex determination and gonadal development through expression screening and loss-of-function analyses of individual candidate genes and may help to explain the paucity of genes in which variations have been found to cause human disorders/differences of sex development.
Cooperation in Face and Dignity Cultures: Role of Moral Identity and Gender (2015)

We examined the effects gender and moral identity on collaborative behavior among Face (Chinese) and Dignity (Canadian) cultures. 105 participants engaged in a dyadic intracultural interaction via the Fire Sim computer game. Each participant was assigned a village and was tasked to protect the village from seasonal fires. Participants had the option of requesting or providing help to the neighboring village, i.e. Their counterpart. We examined collaborative behavior by measuring help given, while controlling for help request. Using theories of face and dignity cultures, moral identity, and gender roles, we predicted and found that overall, Chinese individuals were less helpful than Canadians. This effect was stronger for males than females. Interestingly, more helping behavior was observed among Canadians with high levels of internal moral identity. Yet, this effect was not observed among Chinese individuals. Theoretical and practical implications for collaboration across culture are discussed.
DSP based data acquisition for RHIC (2002)

A flexible data acquisition platform has been developed for use in RHIC beam instrumentation systems. By incorporating a floating point digital signal processor (DSP) and standard input/output modules, this system can acquire and process data from a variety of beam diagnostic devices. The DSP performs real time corrections, filtering, and data buffering to greatly reduce control system computation and bandwidth requirements. We will describe the existing hardware and software while emphasizing the compromises required to achieve a flexible yet cost effective system. Applications in several instrumentation systems currently under construction will also be presented.
Magnesium‐chloride‐supported high‐mileage catalysts for olefin polymerization. III. Electron paramagnetic resonance studies (1982)

Abstract Electron paramagnetic resonance (EPR) was used to study a MgCl 2 ‐supported, high‐mileage olefin polymerization catalyst. Anhydrous Toho MgCl 2 was the starting material. Treatment with HCl at an elevated temperature, ethyl benzoate by ball‐milling, p ‐cresol, AlEt 3 , and TiCl 4 produced a catalyst that contained a single EPR observable Ti +3 species A, which was strongly attached to the catalyst surface, had a D 3h symmetry, and no other Ti +3 ion in an immediately adjacent site. Species A constitutes only 20% of all the trivalent titaniums; the remainder is EPR‐silent and may be attributed to those Ti +3 ions that have adjacent sites occupied by one or more Ti +3 ions. Activation with preformed AlEt 3 /methyl‐ p ‐toluate complexes produced a single Ti +3 species (C) with rhombic symmetry and displaying 27 Al superhyperfin splitting which has attributes for a stereospecific active site. This species is unstable under polymerization conditions and is transformed to another species with axial symmetry and solubilization. Both processes could lead to catalyst deactivation and loss of stereospecificity. Catalysts activated by AlEt 3 and methyl‐ p ‐toluate separately in various sequential orders produced a multitude of EPR‐observable Ti +3 species with varying degrees of motional freedom deemed detrimental to stereospecific polymerization of α‐olefins.
Hierarchical nanoporous metals as a path toward the ultimate three-dimensional functionality (2017)

Nanoporous metals prepared via dealloying or selective leaching of solid solution alloys and compounds represent an emerging class of materials. They possess a three-dimensional (3D) structure of randomly interpenetrating ligaments/nanopores with sizes between 5 nm and several tens of micrometers, which can be tuned by varying their preparation conditions (such as dealloying time and temperature) or additional thermal coarsening. As compared to other nanostructured materials, nanoporous metals have many advantages, including their bicontinuous structure, tunable pore sizes, bulk form, good electrical conductivity, and high structural stability. Therefore, nanoporous metals represent ideal 3D materials with versatile functionality, which can be utilized in various fields. In this review, we describe the recent applications of nanoporous metals in molecular detection, catalysis, 3D graphene synthesis, hierarchical pore formation, and additive manufacturing (3D printing) together with our own achievements in these areas. Finally, we discuss possible ways of realizing the ultimate 3D functionality beyond the scope of nanoporous metals.
Logic Programming Using Parallel Associative Operations (1984)

In order to provide performance improvements in the execution of large logic programs, it is highly desirable to investigate the relationships between logic, data-base systems and knowledge-based systems in the context of massively parallel architectures. This paper presents a model for the interpretation of logic programs in this type of environment and overviews the algorithms under development. An interpreter that implements the model has been demonstrated in simulations on a number of small programs. Implementation requires that only a small set of hardware primitives be available, these have been successfully implemented on a working prototype machine, DADO. Current research aims to develop the model into a practical and efficient logic programming system for use on the machine.
Umbilical cord blood collection: do patients really understand? (2007)

Obstetricians should assume that pregnant women are poorly informed about cord blood banking. The decision making process should be conducted with the goal of ensuring every pregnant woman the opportunity to make a well informed decision about cord blood banking.
In-silico prediction of surface residue clusters for enzyme-substrate specificity (2004)

One of the most remarkable properties of enzyme-substrate binding is the high substrate specificity among homologous enzymes. Identification of regions in enzymes that play an important role in substrate recognition presents an opportunity to understand their basic molecular mechanisms. Current methods are limited to identifying conserved residues, ignoring potential contributions of non-conserved residues. Our method overcomes this limitation. In case studies, we investigated several highly homologous enzymatic protein pairs such as guanylyl vs. adenylyl cyclases and lactate vs. malate dehydrogenases, and applied our method on plant and cyano-bacterial RuBisCos. We identified several critical mono-residue and multi-residue clusters that were consistent with experimental results. Some of the identified clusters, primarily the mono-residue ones, represent residues that are directly involved in enzyme-substrate interactions. Others, mostly the multi-residue ones, represent residues vital for domain-domain and regulator-enzyme interactions, indicating their complementary roles in specificity determination.
Quantum Tunneling in the Midrange Vibrational Fundamentals of Tropolone (2006)

The Fourier transform infrared spectrum of tropolone(OH) vapor in the 1175-1700 cm(-1) region is reported at 0.0025 and 0.10 cm(-1) spectral resolutions. The 12 vibrational fundamentals in this region of rapidly rising vibrational state density are dominated by mixtures of the CC, CO, CCH, and COH internal coordinates. Estimates based on the measurement of sharp Q branch peaks are reported for 11 of the spectral doublet component separations DS(v) = |Delta(v) +/- Delta(0)|. Delta(0) = 0.974 cm(-1) is the known zero-point splitting, and three a(1) modes show tunneling splittings Delta(v) approximately Delta(0), four b(2) modes show splittings Delta(v) approximately 0.90Delta(0), and the remaining four modes show splittings Delta(v) falling 5-14% from Delta(0.) Significantly, the splitting for the nominal COH bending mode nu(8) (a(1)) is small, that is, 10% from Delta(0). Many of the vibrational excited states demonstrate strong anharmonic behavior, but there are only mild perturbations on the tautomerization mechanism driving Delta(0). The data suggest, especially for the higher frequency a(1) fundamentals, the onset of selective intramolecular vibrational energy redistribution processes that are fast on the time scale of the tautomerization process. These appear to delocalize and smooth out the topographical modifications of the zero-point potential energy surface that are anticipated to follow absorption of the nu(v) photon. Further, the spectra show the propensity for the Delta(v) splittings of b(2) and other complex vibrations to be damped relative to Delta(0).
A Zwitterionic ABC Triblock Copolymer That Forms a “Trinity” of Micellar Aggregates in Aqueous Solution (2004)

A PEO-based macroinitiator was used to first polymerize 2-(diethylamino)ethyl methacrylate (DEA) and then 2-hydroxyethyl methacrylate (HEMA) in a one-pot synthesis via ATRP in methanol at 20 °C. The resulting PEO−PDEA−PHEMA triblock copolymer precursors were successfully converted into the corresponding PEO−PDEA−PSEMA zwitterionic triblock copolymers by esterification of the hydroxy groups on the HEMA block using excess succinic anhydride in pyridine under mild conditions. A “trinity” of micellar aggregates was formed by these PEO−PDEA−PSEMA triblock copolymers in aqueous solution simply by adjusting the solution pH at ambient temperature. The driving forces for forming these three types of micelles were hydrogen-bonding, interpolyelectrolyte complexation, and hydrophobic interactions, respectively. The hydrogen-bonded PSEMA/PEO-core micelles that were formed at low pH were disrupted at higher temperatures or by addition of methanol, leading to PSEMA-core aggregates. The PSEMA/PDEA interpolyelectrolyte micelles formed at around the IEP were very sensitive to the ionic strength of the aqueous solution. Dilution of these solutions resulted in swollen micelles, and eventually dissociation occurred. As far as we are aware, the rich aqueous solution behavior of this new class of ABC triblock copolymers is unprecedented since, for the first time, three types of micelles are formed in aqueous solution by a single-component system.
A wearable device to assist the evaluation of workers health based on inertial and sEMG signals (2021)

This paper describes a wearable monitoring system for sEMG and coherent motion data signals that is primarily aimed at real-time tracking of workers' activity for the analysis and prevention of Work-related Musculoskeletal Disorders (WMSDs). The device supports the data recording, real-time streaming, and analysis of up to four 9-axis inertial units and up to 8 independent single-ended surface Electromyography (sEMG) signals. The device has been developed to acquire, elaborate and integrate information related to the arm motion and forces with a minimal encumbrance on the operator's arm. The paper discusses the design of the device and presents a validation of the measuring capabilities of the system.
Computer-aided administration of a radiology equipment insurance program. (1993)

The Medical College of Georgia's radiology department has developed computer software that helps the department manage its radiology equipment insurance program. By providing clear menus and choice boxes instead of manual typing wherever possible, the software minimizes the time spent on data entry and management functions. In addition, the software helps track vendor invoices and unreimbursed claims, and maintains a service call log. It also provides a bar-coded service ticket for use by in-house engineers. Completed tickets, which are copied and filed, have replaced ledger books. Furthermore, the software helps the department comply with JCAHO requirements, since service tickets link the documentation of quality control problems to their resolution.
Control of the temperature on rapid thermal processing by AI based techniques (1997)
