A study on the morphology and density of flocus I.The fractal structure of floc (2000)

Random flocs formed under conventional operation condition are of fractal nature. There is a simple relation of D f=3-K p between D f, the fractal dimension and Kp, the parameter in the floc density function ρ e∝d p -K p .Through a stepwise agglomeration model, the process of floc growth was discussed. It was shown that at each agglomeration step, additional void water was entrapped in the floc and thus affected floc density and structure. By analyzing the parameters of the agglomeration model, it is further proved that a floc formed in this manner is of fractal nature with its fractal dimension depending on the void ratio e and agglomerated particle number m. A decrease in e or increase in m results in an increase in D f, which implies a transition of floc from loose structure to compact one. Mechanical syneresis and one by one attachment are two operation modes for compact floc formation.

The effects of excessive heat on heat-activated membrane currents in cultured dorsal root ganglia neurons from neonatal rat (2002)

The effects of high temperature (53-61 degrees C) on membrane currents (I(heat)) or depolarization (V(heat)) induced by noxious heat were studied in cultured dorsal root ganglia neurons from neonatal rats using the whole cell patch clamp technique. I(heat) or V(heat) produced by 3 s ramps of increasing temperature between 43 and 50 degrees C exhibited a fast slope (Q10>10) that was similar both during rising and falling temperature (n=85). Temperatures exceeding 52 degrees C resulted in slowdown in the recovery of I(heat), and the threshold for inducing I(heat) was shifted to lower temperatures in successive trials. These high temperatures (54-60 degrees C) caused a linear and incomplete recovery of I(heat) (Q10 decreased to <5; 4.5 +/- 0.4; n=17) and in successive trials the threshold of I(heat) decreased to temperatures close to that in the bath. The neurons, however, remained sensitive to capsaicin and to decreased extracellular pH. It is suggested that exposure of nociceptive neurons to excessive noxious heat results in an irreversible decrease of the energy barrier between the resting and activated state of the protein structures responsible for generation of I(heat). This may explain the sensitization of nociceptors after heat injury.
Syncristallisation Organique avec Peritexie. Cas du Système Binaire Fluoro-2 Naphtalene - Naphtol-2 (1979)

Abstract The phase relations in the x 2-fluoronaphthalene-(1 - x) 2-naphthol system have been determined by X-ray diffraction, DTA and heating optical microscopy. Three stable solid phases occur: β which is a solid solution of 2-fluoronaphthalene in the low temperature form of 2-naphthol (OHII), α which is a solid solution of 2-fluoronaphthalene in the high temperature form of 2-naphthol (OHII) and α’ which is a solid solution of 2-naphthol in 2-fluoronaphthalene (FI). The structure of the β phase is derived from the ordered structure OHII (monoclinic, Ia, Z = 8) whereas the structure of the α and α’ phases are respectively derived from the disordered structures OHI and FI (monoclinic, P21/a, Z = 2). The main features of the phase diagram are a transition zone (II-I) for solid solutions rich in 2-naphthol, the limits of which at 293 K are x = 0.20 and x = 0.45 and a peritectic at T p = 338 K with a miscibility gap from x = 0.60 to x = 0.87; the limits of demixion at 293 K are x = 0.53 and x = 0.95. This example points out that volume relationships are not decisive in organic solid-state solubilities. Le diagramme de phases du systeme x fluoro-2 naphthalene-(I - x) naphtol-2 a été déterminé par méthodes radiocristallographique, thermique et optique. Il est de type Roozeboom IV avec un péritectique situé à x = 0.87 et à T p = 338 K. Il est caractérisé également par un phénomene de polymorphisme Il-I affectant des solutions solides riches en naphtol-2 (forme II: monoclinique, Ia, Z = 8 - forme I: monoclinique, P21/a, Z = 2, structure désordonnée). Cet exemple met en lumière l'insuffisance des seules considerations d'homéomorphisme moléculaire pour décrire les conditions de formation d'un cristal mixte organique.
Role of Citicoline in the Management of Traumatic Brain Injury (2021)

Head injury is among the most devastating types of injury, specifically called Traumatic Brain Injury (TBI). There is a need to diminish the morbidity related with TBI and to improve the outcome of patients suffering TBI. Among the improvements in the treatment of TBI, neuroprotection is one of the upcoming improvements. Citicoline has been used in the management of brain ischemia related disorders, such as TBI. Citicoline has biochemical, pharmacological, and pharmacokinetic characteristics that make it a potentially useful neuroprotective drug for the management of TBI. A short review of these characteristics is included in this paper. Moreover, a narrative review of almost all the published or communicated studies performed with this drug in the management of patients with head injury is included. Based on the results obtained in these clinical studies, it is possible to conclude that citicoline is able to accelerate the recovery of consciousness and to improve the outcome of this kind of patient, with an excellent safety profile. Thus, citicoline could have a potential role in the management of TBI.
Body Mass Index, Percent Body Fat and Visceral Fat in Relation to Dietary Fat and Fiber Intake among University Females (2015)

Recent economic upliftment has brought many changes in the food choices and eating habits from home made to fast foods. This shift in the area of nutrition has given rise to overweight and obesity. Considering this the present study was planned to 1) determine the prevalence of overweight and obesity in a sample of university students 2) Find the relationship between the body composition and dietary fat and fibre intake. A total of 300 university females, 18-30+ years were randomly selected from all the colleges at the University of Hail for the present study. A Self-administered questionnaire was given, and the Body composition were measured with the help of bio-electric impedance analysis technique. Data were analysed using SPSS -17 software. The results indicated that 22% of the students were overweight and 21.3% were obese. The mean percent body fat as well as visceral fat exceeded its normal limits in around 44% of the participants. Vegetables and fruits, except dates, were not frequently consumed by most of the participants with a mean intake of fibre as 14g/day. Significant positive correlations were found among Body Mass Index (BMI), Body Fat% and Visceral Fat level. Strong positive correlation was also found between BMI and fat intake (P&lt; 0.01), whereas the body composition and fiber intake was found to be inversely correlated (P&lt;0.01). Findings of present study suggest that there is need for coordinated efforts at all levels to reduce the prevalence of obesity and high percentage of body fat, and to develop healthy eating habits in young generation.
Deranged Mineral Content in the Bone of Patients with Chronic Renal Failure, Estimated by Computed Tomography (1985)

To evaluate the extent of renal osteodystrophy in patients with chronic renal failure, the CT numbers of the lateral condylus and mid-shaft of the femur were measured. To adjust for variation due to measurement conditions, calibration phantom was simultaneously scanned with the femur. The CT numbers of the lateral condylus were significantly lower than the control in both nondialyzed (p less than 0.005) and dialyzed patients (p less than 0.05). The CT numbers of the mid-shaft of the femur in dialyzed patients correlated significantly to the duration of hemodialysis (r = 0.807, p less than 0.001). In 15 patients subjected to both CT scan and the photon absorptiometry, the CT numbers of the lateral condylus positively correlated to the mineral content of the radial (r = 0.57) and ulnar (r = 0.69) bones as calculated by photon absorptiometry. These results indicate that the CT scan can be used to estimate bone mineral content quantitatively, and is useful tool for evaluating renal osteodystrophy in patients with chronic renal failure.
Synthesis and Self-Assembling of Amphiphilic Diblock Copolymers of 2,3,4,5,6-Pentafluorostyrene (2019)

Amphiphilic diblock copolymers (DC) of 2,3,4,5,6-pentafluorostyrene and 2-hydroxyethyl methacrylate were prepared for the first time by two-step reversible addition–fragmentation chain transfer (RAFT) polymerization. The morphology of films of diblock copolymers that have a composition close to equimolar was studied by transmission electron microscopy. The observed microphase separation and formation of spherical nanodomains is not typical for equimolar diblock copolymers and seems to result from hydrogen bonding between the hydroxyl and carbonyl groups (OH···OH and C=O···HO) in poly(2-hydroxyethyl methacrylate) blocks. Obviously, it is the ability of diblock copolymers to self-organization is the cause of formation of fabric coatings with low surface energy (γ = 11.9 mJ/m2) and relatively large water contact angles ( $${{\theta }^{{{{{\text{H}}}_{{\text{2}}}}{\text{O}}}}}$$ = 120° ± 6°) and diiodomethane ( $${{\theta }^{{{\text{C}}{{{\text{H}}}_{2}}{{{\text{I}}}_{{\text{2}}}}}}}$$ = 93° ± 2°).

Design and Implementation of an Around View Monitoring System of Selecting Scope of View (2014)

Assistance System) such as navigation and GPS, and driver's infotainment devices such as DVD players have been produced. AVM systems of these driver convenience systems support safety driving by providing situations around the vehicle to a driver. A driver can't fully monitor the situation around the vehicle at a glance using only rearview mirrors, a room mirror, and front and rear cameras, and using of only these devices causes blind spot which hinders driver's safety. Blind spot is cause of personal injury and vehicle damage when parking vehicle, passing on a narrow street and turning left or right.
PathOrganic – Risks and Recommendations Regarding HumanPathogens in Organic Vegetable Production Chains (2009)

Adult respiratory distress syndrome (ARDS) culminates in inadequate oxygen delivery to the tissues. There are numerous inciting factors for this syndrome. Several therapies including the prophylactic use of antibiotics and steroids are controversial; even mechanical ventilatory support has controversial elements. The cornerstone of treatment remains supportive care until the cause of ARDS has resolved.
Ambiguity in radar and sonar (1998)

We introduce a new ambiguity function for general parameter estimation problems in curved exponential families. We focus the presentation on passive and active radar and sonar location mechanisms. The new definition is based on the Kullback (1978) directed divergence and reflects intrinsic properties of the model. It is independent of any specific algorithms used in the processing of the signals. For the active single target problem, we show that our definition is equivalent to Woodward's (1953) radar narrow-band ambiguity function. However, the new ambiguity is much broader, handling radar/sonar problems when there are unknown parameters (e.g., unknown power level in active systems), when the signals are random (e.g., passive systems), when the signals are wideband, or when there are model mismatches. We illustrate the new ambiguity in localization problems in multipath channels.
SNR Maximization in Beyond Diagonal RIS-Assisted Single and Multiple Antenna Links (2023)

Reconfigurable intelligent surface (RIS) architectures not limited to diagonal phase shift matrices have recently been considered to increase their flexibility in shaping the wireless channel. One of these beyond-diagonal RIS or BD-RIS architectures leads to a unitary and symmetric RIS matrix. In this letter, we consider the problem of maximizing the signal-to-noise ratio (SNR) in single and multiple antenna links assisted by a BD-RIS. The Max-SNR problem admits a closed-form solution based on the Takagi factorization of a certain complex and symmetric matrix. This allows us to solve the max-SNR problem for SISO, SIMO, and MISO channels.

Efficacy of current molecular cytogenetic protocols for the diagnosis of chromosome aberrations in tumor specimens. (1996)

Molecular cytogenetics provides a powerful link between molecular genetic analysis and chromosome morphology, allowing one to pinpoint structurally aberrant chromosome regions on the molecular level. Fluorescence in situ hybridization with selected DNA probes allows the design of efficient and sensitive tools for the diagnosis of chromosomal aberrations present in tumor cells. Comparative genomic hybridization (CGH) allows the identification of chromosomal imbalances in a comprehensive manner, and is applied to solid tumors and hematological malignancies in order to (i) identify clonal differences within a specimen, (ii) contribute to tumor classifications, (iii) identify recurrent chromosomal gains and losses as starting points for the characterization and isolation of pathogenetically relevant genes, such as proto-oncogenes and tumor suppressor genes respectively, (iv) identify imbalances of prognostic relevance, (v) detect high-copy-number amplification and other markers of genetic instability, and (vi) analyze chromosomal imbalances during tumor progression.
RETRACTED: Correlations between parameters of glycaemic variability and foetal growth, neonatal hypoglycaemia and hyperbilirubinemia in women with gestational diabetes (2023)

The diagnosis of gestational diabetes mellitus (GDM) is important to prevent maternal and neonatal complications. This study aimed to investigate the feasibility of parameters of glycaemic variability to predict neonatal complications in women with GDM. A retrospective study was conducted on pregnant women tested positive at the oral glucose tolerance test (OGTT) during 16-18 or 24-28 weeks of gestation. Glycaemic measures were extracted from patients' glucometers and expanded to obtain parameters of glycaemic variability. Data on pregnancy outcomes were obtained from clinical folders. Descriptive group-level analysis was used to assess trends in glycaemic measures and foetal outcomes. Twelve patients were included and analysed, accounting for 111 weeks of observations. The analysis of trends in parameters of glycaemic variability showed spikes of glycaemic mean, high blood glucose index and J-index at 30-31 weeks of gestation for cases with foetal macrosomia, defined as foetal growth >90° percentile, neonatal hypoglycaemia and hyperbilirubinemia. Specific trends in parameters of glycaemic variability observed at third trimester correlate with foetal outcomes. Further research is awaited to provide evidence that monitoring of glycaemic variability trends could be more clinically informative and useful than standard glycaemic checks to manage women with GDM at delivery.
Annotations capturing cell type-specific TF binding explain a large fraction of disease heritability (2019)

Regulatory variation plays a major role in complex disease and that cell type-specific binding of transcription factors (TF) is critical to gene regulation. However, assessing the contribution of genetic variation in TF-binding sites to disease heritability is challenging, as binding is often cell type-specific and annotations from directly measured TF binding are not currently available for most cell type-TF pairs. We investigate approaches to annotate TF binding, including directly measured chromatin data and sequence-based predictions. We find that TF-binding annotations constructed by intersecting sequence-based TF-binding predictions with cell type-specific chromatin data explain a large fraction of heritability across a broad set of diseases and corresponding cell types; this strategy of constructing annotations addresses both the limitation that identical sequences may be bound or unbound depending on surrounding chromatin context and the limitation that sequence-based predictions are generally not cell type-specific. We partitioned the heritability of 49 diseases and complex traits using stratified linkage disequilibrium (LD) score regression with the baseline-LD model (which is not cell type-specific) plus the new annotations. We determined that 100 bp windows around MotifMap sequenced-based TF-binding predictions intersected with a union of six cell type-specific chromatin marks (imputed using ChromImpute) performed best, with an 58% increase in heritability enrichment compared to the chromatin marks alone (11.6× vs. 7.3×, P = 9 × 10-14 for difference) and a 20% increase in cell type-specific signal conditional on annotations from the baseline-LD model (P = 8 × 10-11 for difference). Our results show that TF-binding annotations explain substantial disease heritability and can help refine genome-wide association signals.
Permanent electric dipole moment of copper monoxide, CuO (2010)

A number of low-rotational lines of the A Σ2−←X Π23/2(0,0) subband of a molecular beam of copper monoxide, CuO, were recorded field free and in the presence of a static electric field. A set of optimized fine and hyperfine parameters for the A Σ2−(υ′=0) state was produced from the analysis of the field-free spectrum. The permanent electric dipole moments μ for the A Σ2−(υ=0) and X Π23/2(υ=0) states were determined to be 1.12(71) and 4.57(3) D, respectively, from the analysis of the observed Stark shifts. The error of the experimentally determined μ value for the X Π23/2(υ=0) state is approximately ten times less than that for the previously determined value: μ=4.45(30) D [T. C. Steimle et al., J. Chem. Phys. 87, 5670 (1987)]. The experimental μ values are compared with theoretical predictions.
Modeling of the Grinding Wheel Topography Depending on the Recipe-Dependent Volumetric Composition (2017)

The prediction of the grinding process result, such as the workpiece surface quality or the state of the edge zone depending on the used grinding wheel is a great challenge for todays manufacturers and users of grinding tools. This is mainly caused by inadequate predictability of the forces and temperatures acting in the process, which depend on the topography of the grinding wheel coming into contact with the workpiece during the grinding process. The topography of a grinding wheel depends, beside the dressing process, on the structure of the grinding wheel, which is determined by its recipe-dependent volumetric composition. The structure of a grinding tool therefore determines its application behavior strongly. As a result, the knowledge-based prediction of the grinding wheel topography and its influence on the machining behavior is only possible if the recipe-dependent grinding wheel structure is known. In this paper, an innovative approach for modeling the grinding wheel structure and the resultant grinding wheel topography is discussed. The overall objective of the underlying research project was to create a mathematical-generic grinding wheel model in which the spatial arrangement of the components grains, bond and pores is simulated in a realistic manner starting from the recipe-dependent volumetric composition of a grinding wheel. With this model it is possible to determine the resulting grinding wheel structure and the grinding wheel topography of vitrified and synthetic resin-bonded CBN grinding wheels and thus to predict their application behavior. The originality of the present research results is a generic approach for the modeling of grinding wheels, taking into account the entire grinding wheel structure and build up the topography based on it. Using original mathematical methods, the components of grinding wheels were analyzed and distribution functions of the components were determined. Thus the statistical character of the grinding wheel structure was taken into account. In future, the presented model opens new perspectives in order to optimize and to increase the productivity of grinding processes.
A RELIABLE SORTING ALGORITHM ON HYPERCUBE MULTICOMPUTERS (1995)

In this paper, we present an algorithm-based fault-tolerant technique, namely the median-splitting strategy, for designing a reliable sorting algorithm. Combining the median-splitting strategy with bitonic sorting algorithm, a reliable sorting algorithm is proposed on the hypercube multicomputers. By the strategies of duplicating data and rollback, the proposed algorithm can detect transient faults and automatically correct errors without any hardware modification. We also implement our algorithm on nCUBE/1 hypercube machines with 64 processors. The simulation results show that our sorting algorithm is reliable and cost-effective.
Numerical and Experimental Investigations of an Elasto-Flexible Membrane Wing at a Reynolds Number of 280,000 (2017)

This work presents numerical and experimental investigations of an elasto-flexible membrane wing at a Reynolds number of 280,000. Such a concept has the capacity to adapt itself to the incoming flow offering a wider range of the flight envelope. This adaptation is clearly observed in the numerical study: the camber of the airfoil changes with the dynamic pressure and the angle of attack, which permits a smoother and delayed stall. The numerical results, obtained from Fluid Structure Interaction (FSI) simulations, also show that the laminar-turbulent transition influences the aerodynamic characteristics of the wing, as it directly affects the pressure distribution on the membrane and the geometry of the airfoil. Two different turbulence models were therefore tested. Furthermore, experimental investigations are considered in this paper to estimate the precision of the FSI simulations. It appears that the FSI study overestimates the lift coefficient, and the drag coefficient is undervalued, which can be explained by dynamic calibration of the model. Nevertheless, the velocity field obtained with the hot-wire anemometry system shows good agreement on the upper side of the model. The membrane deflection measurements also appear to be consistent with the expected geometry of the deformed airfoil from the FSI simulations.
