The human ovarian cancer cell line CABA I: A peculiar genetic evolution

The objective of this study was to study the human ovarian cancer cell line CABA I by means of short tandem repeats (STR) profiling and cytogenetic analysis in order to prevent future misidentification or cross-contamination and verify its stability during in vitro cultivation. To this end, cells at passages 18 and 38 were analyzed using cytogenetic techniques in order to verify possible chromosomal aberrations and the karyotypic evolution of this cell line; GTG-banding and FISH were also performed. For STR analysis, DNA was extracted using the automated extractor MagNA pure and analyzed by means of PowerPlex 16 HS. STR profiles were analyzed by GeneMapper 3.2. 1 software. Whereas comparative cytogenetic analysis of CABA I cells at passage 18 and 38 has demonstrated considerable genetic instability, we found that STR profiles were essentially unaltered in both analyzed passages, suggesting that the STR profile is reliable and could be used for the regular authentication of CABA I over time. It should be emphasized, however, that of the 16 loci generally used in human STR profiles, only 3 were properly detectable in CABA I. The data highlight that the CABA I cell line demonstrates an anomalous STR profile that does not fully adjust the criteria currently used for the identification of human cells; in spite of this, it remains stable during the in vitro maintainance. Moreover, the genetic instability of the CABA I cell line overlaps with those observed in vivo in tumor cells, making it a suitable candidate to analyze, in vitro, the peculiar genetic evolution of ovarian cancer cells.
Homomorphic encryption for secure information retrieval from the cloud

Cloud computing has established itself as a major way of controlling the technology infrastructure costs borne by the organizations. A cost-sensitive organization would most likely find a certain amount of delay to be acceptable while retrieving information from the cloud. The main focus of this paper is on cost-efficiency and privacy. Three secure search protocols, namely Ostrovsky protocol, COPS protocol and EIRQ protocol are discussed in this paper. Each of these protocols incrementally improves upon the basic keyword search. Ostrovsky protocol offers privacy. COPS protocol aggregates the search results and achieves cost efficiency. EIRQ allows the users to retrieve a certain percentage of files after the users assign ranks to the queries themselves. A comparison of these three protocols is followed by the future work that could be carried out in this area.
A New Scan Design Technique Based on Pre-Synthesis Thru Functions

VLSI design has moved from bottom-up design approach to top-down design methodology with the aid of advanced computer-aided design (CAD) technology. This paper introduces a new scan design technique as a design-for-test (DFT) method for sequential circuits by exploiting the information of thru functions available at high-level description of the circuit. This DFT method reduces the number of flip-flops to be converted into scan flip-flops because some existing thru functions allow the flip-flops to be controllable from primary inputs or observable at primary outputs or both. Moreover, the DFT method can be applied to both structural RT-level circuits and gate-level circuits. The paper also presents a test generation procedure for the augmented sequential circuits using a combinational ATPG tool. The experimental results show the comparison of our DFT method with conventional scan techniques in terms of hardware overhead, test generation time, fault coverage, fault efficiency and test application time
Generalized Array Factor Approach to the Assessment of Discrete Tapered Nonuniform Leaky-Wave Antenna

A generalization of the array factor approach of a nonuniform leaky-wave antenna (LWA) is proposed for the modeling of discrete tapered LWAs. The demonstration is based on the Fourier transform of the illumination amplitude of an LWA and is thus quite general. This analysis approach can be helpful for design. When it is used in combination with classical taperization techniques, it provides an easy and powerful conception tool. The validity of the method is demonstrated with the Holey and the Honey LWAs. Taylor and cosine distributions were simulated and sidelobe level reduction up to -40 dB were obtained. A Holey antenna designed to work at 1.7 GHz with a cosine distribution was realized. Its radiation pattern was measured and it shows an acceptable agreement with theory and numerical simulations.
Nucleation and growth of a flux instability in superconducting YBa2Cu3O7-x films.

Using a high speed magneto-optic technique we have investigated the dynamics of a new flux instability in thin superconducting YBa 2 Cu 3 O 7-x films exposed to an external magnetic field of several 10 -2 T. The instability was nucleated by a 5 ns laser pulse, which heated a small spot of the sample in a region of high shielding currents. Two subsequent regimes in the development of the instability are discovered, which give rise to strikingly different flux distributions. The formation of flux branches, which are characteristic for the second stage, occurs on a time scale of a hundred nanoseconds
Mitoxantrone–cyclophosphamide–rituximab: an effective and safe combination for indolent NHL

Treatment for extensive indolent lymphoma should combine optimization of efficacy without excessive toxicity. Rituxan may be an ideal agent for combinations with chemotherapy because of its non‐cross‐resistant toxicity profile and the potential for synergism. We present the results of 32 patients with indolent B‐cell NHL who received a novel three‐drug combination designed with the intent of preservation of both efficacy and quality of life. Patient characteristics were as follows, median age, 58 years (36–75 years); histology, follicular 16, SLL/CLL five, lymphoplasmacytic six, marginal cell five; relapsed or refractory, 10; untreated, 22. Patients first received cyclophosphamide 800 mg/m2 and mitoxantrone 8 mg/m2, iv on the same day, every 3 weeks for two cycles. Subsequently, patients received rituximab followed by mitoxantrone 8 mg/m2 every 2 weeks for four cycles. The regimen, and particularly rituximab, was extremely well tolerated. Grade I/II, infusion‐related toxicity was noted in 10%. Six patients achieved a PR and 23 a CR for an overall response of 90% (95% CI: 79–100%). The actuarial median TTP for all patients was 30 months. Molecular remissions were noted in 8/14 patients tested in CR. We conclude that the cyclophosphamide–mitoxantrone–rituxan (CyMiR) regimen is effective and extremely well tolerated. Furthermore, rituximab infusion‐related morbidity is nearly completely eliminated. Copyright © 2003 John Wiley & Sons, Ltd.
Development and Validation of a Ureteral Anastomosis Simulation Model for Surgical Training

Objective To develop and validate a new ureteral anastomosis simulation model. Methods We designed a training model to simulate the task of ureteral anastomosis required for ureteroneocystostomy that is suitable for robotic and laparoscopic approaches. Face validity was measured using questions related to surgical authenticity and educational value of the model. Construct validity was measured by comparing scores using Global Operative Assessment of Laparoscopic Skills Scale (GOALS) scale between “procedure experts,” “robotic experts,” and “trainees” groups. One-way analysis of variance was used to compare differences in the scores and operating times between the 3 groups. Associations between previous surgical experience and performance scores were measured using the Spearman rho correlation coefficient. Results Four urologists experienced with robotically assisted ureteroneocystostomies were included in the procedure experts group. The robotic experts group consisted of 5 gynecologists experienced in robotic surgery. The trainees group consisted of 12 urology and gynecology upper-level residents and fellows. All experts agreed or strongly agreed that the model was authentic to the live procedure and a useful training tool. Mean (SD) total GOALS scores were significantly better for the procedure experts group compared to the robotic experts group and to the trainees group (P=0.02 vs P=0.004, respectively). The robotic experts group’s GOALS scores were also significantly higher than that of the trainees group (P=0.05). There were no differences in mean times required to complete the procedure. Surgical experience moderately correlated with scores on all 3 assessment scales. Conclusions Superior performance on the model by more experienced surgeons demonstrates evidence of construct validity. This authentic and useful model allows surgeons to learn and practice the ureteral anastomosis portion of the ureteral reimplantation surgeries before operating on a live patient.

Goal-Setting and Task Performance among Nigerian Managers in a Cross-Cultural Context

This study assessed goal-setting and task performance among Nigerian managers. Data were collected from 521 subjects including 176 Yoruba, 147 Igbo and 198 Hausa/Fulani managerial employees in Lagos, Nigeria. The relevant scales of the 57-item questionnaire designed by Mendonca and Kanungo (1994) were used to obtain measures of the dependent variables. Mean scores in goal setting and performance-intrinsic reward contingency were highest among the Yoruba managers followed by Hausa/Fulani and Igbo managers respectively. Mean score in task significance was highest among the Igbo managers followed by Yoruba and Hausa/Fulani managers respectively. Mean score in performance-extrinsic reward contingency was highest among the Hausa/Fulani managers followed by Yoruba and Igbo managers respectively. One-way ANOVA showed cultural differences in performance-intrinsic reward contingency (p< .05) and task significance (p< .01) but not in goal-setting and performance-extrinsic reward contingency respectively. The results were discussed in terms of the influence of culture on human resources management practices and that managers who value performance-intrinsic reward allocation should engage in goal-setting more than the others.
Distributed and Collaborative Beamforming in Wireless Sensor Networks: Classifications, Trends, and Research Directions

Distributed and collaborative beamforming (DCBF) scheme in wireless sensor networks (WSNs) is receiving new-found interest in recent times due to the rapid advancements in wireless technology and embedded systems. Although studies on distributed and collaborative beamforming have been carried out for more than ten years, the DCBF was initially considered impractical due to high complexity and hardly achievable requirements. It gained prominence only in the past few years as small wireless communication electronic sensors with high processing capability became easily available. Recent works showcasing distributed and collaborative beamforming as a suitable solution for 5G communication systems such as mm-wave communication and machine to machine communications has further ignited the interest in this research field. Motivated by these factors, this paper presents a survey on the research trends of distributed and collaborative beamforming in WSNs. We provide classifications of the DCBF research areas and conduct an extensive review of the various proposals which have appeared in the literature for each classification. This survey uncovered that majority of existing research can be broadly divided into four major research trends: beampattern analysis, power and lifetime optimization, synchronization, and finally, prototype design. The inherent features, constraints and challenges of each research category in the distributed and collaborative beamforming are presented and the lessons learned from the shortcomings of previous research are summarized. Finally, this paper has unveiled open research directions in the field of distributed and collaborative beamforming in WSNs.
Collaborative Control of Cell Cycle Progression by the RNA Exonuclease Dis3 and Ras Is Conserved Across Species

Dis3 encodes a conserved RNase that degrades or processes all RNA species via an N-terminal PilT N terminus (PIN) domain and C-terminal RNB domain that harbor, respectively, endonuclease activity and 3′–5′ exonuclease activity. In Schizosaccharomyces pombe, dis3 mutations cause chromosome missegregation and failure in mitosis, suggesting dis3 promotes cell division. In humans, apparently hypomorphic dis3 mutations are found recurrently in multiple myeloma, suggesting dis3 opposes cell division. Except for the observation that RNAi-mediated depletion of dis3 function drives larval arrest and reduces tissue growth in Drosophila, the role of dis3 has not been rigorously explored in higher eukaryotic systems. Using the Drosophila system and newly generated dis3 null alleles, we find that absence of dis3 activity inhibits cell division. We uncover a conserved CDK1 phosphorylation site that when phosphorylated inhibits Dis3’s exonuclease, but not endonuclease, activity. Leveraging this information, we show that Dis3’s exonuclease function is required for mitotic cell division: in its absence, cells are delayed in mitosis and exhibit aneuploidy and overcondensed chromosomes. In contrast, we find that modest reduction of dis3 function enhances cell proliferation in the presence of elevated Ras activity, apparently by accelerating cells through G2/M even though each insult by itself delays G2/M. Additionally, we find that dis3 and ras genetically interact in worms and that dis3 can enhance cell proliferation under growth stimulatory conditions in murine B cells. Thus, reduction, but not absence, of dis3 activity can enhance cell proliferation in higher organisms.
Harmonics-Based Inhomogeneous Plane-Wave Method (HIPW)

A formulation is presented for fast interactions between subdomains in two-dimensional (2-D) scattering problems. The formulation combines inhomogeneous plane waves with cylindrical harmonic decompositions of fields radiated by the subdomains. It is shown that the complexity of interactions naturally decays with the distance between subdomains and that very few elementary operations are involved at the lowest level. An example of iterative solution for scattering by a collection of cylinders validates the proposed approach.
Could genetic diversity in eastern North Pacific gray whales reflect global historic abundance?

In Reply: Palsbol et al. raise the possibility that our estimates of gray whale genetic diversity could reflect global diversity if a population of gray whales existed in the Southern Hemisphere. However, as they note, no evidence of gray whales has been discovered in the Southern Hemisphere. No fossils or subfossils have been reported, there are no accounts of this species from whaling records, and it is not known whether the specialized feeding requirements of gray whales could have been met in Southern Ocean areas. Although this lack of evidence does not eliminate the possibility of a gray whale population in the Southern Hemisphere, it does indicate a low probability that a large, widespread population existed there recently. In our paper on gray whale abundance before whaling (1), we use a new approach to evaluating “ghost” populations for their potential impact on the genetic diversity of current-day population diversity, as requested by the International Whaling Commission (2).

A Study on Factors Infl uencing Muslim's Consumers Preferences Towards Takaful Products In Malaysia

Since the enactment of the Takaful Act 1984, Malaysia’s Takaful industry has been achieving momentum and increasingly recognized as a signifi cant contributor to Malaysia’s overall Islamic fi nancial system. Hence, for continuing future progress in fi nancial industry’s rapid development, Malaysian government through Bank Negara Malaysia (BNM), invites fi nancial institution across the world to establish Takaful and retakaful operations in Malaysia to conduct foreign currency business. Nowadays, Muslim’s consumers have the option to choose either Takaful or conventional insurance product. In addition, based on the nature of Takaful product descriptions, it has a higher preference since it is Syariah compliant which align with the Islamic regulation. However, the concept of Takaful is still vague to many people even to the Muslim because there is no proper explanation to educate them on lot of hidden advantages of it. Therefore, this study investigates the causal relationship between consumer awareness, perception and religiosity towards Muslim’s consumer preferences on Takaful product. Primary data were collected through series of questions in a questionnaire that were distributed among Muslim’s Takaful customers of selected Takaful agencies. Analysis on the collected data was performed through confi rmatory factor analysis (CFA) and structural equation modelling (SEM) using lavaan package in R software. A CFA result show fi t indices that met the recommended values criteria. In addition, the path analysis in SEM reports that two out of three independent variables are signifi cant contributors to Muslim’s customers’ preferences towards Takaful.
The gait control system of a quadruped walking vehicle

A walking vehicle has potential capability to be developed to an off-road machine with high mobility and adaptivity by using the coordination control of its multi-degrees of freedom. There have been several discussions on the gait control of a walking vehicle, although few have mentioned the total gait control system and any sub-systems integrated into the total structure. This paper discusses the gait control system based on a quadruped walking vehicle developed by the authors. At first, the premises for the discussion are confirmed. Then, the total structure of the control system, consisting of three levels named A, B and C, is clarified. The control algorithm of each level is studied in detail, particularly the three sub-systems belonging to level B, i.e. gait control in xy coordinates, the same in z coordinate and trajectory control of legs taking account up/down swinging. The control algorithm at level C, which regulates the basic reflex motions, is specifically discussed. Finally, these discussions .

Size reduction and radiation optimization on UWB antenna

This paper deals with miniaturization techniques and radiating optimization on UWB antenna in order to make an antenna array. The hard point with size reduction of an antenna is the back radiation, the cross polarization and the antenna adaptation. Several methods to keep the antenna adapted to our bandwidth [300 MHz - 3 GHz] are studied. A detailed study of the travelling wave elementary antenna is proposed. Some techniques are applied to reduce back radiation and cross polarization by the use of slots in order to reduce back radiation and resistive loads in order to reduce surface current levels and side cross polarization.
Familial 5p‐ syndrome

This report concerns a mother and son with a small terminal deletion of the short arm of chromosome 5 (del(5)(qter → pi5.1:). Both mother and son had superficial resemblance to patients with classical Cri‐du‐Chat Syndrome, but lacked the severe mental and growth retardation generally associated with such cases.
A novel mixed approach for detecting overlap in document images

Plagiarism detection is an important task in document processing. Due to increase in electrical resources, it is not possible to check documents for overlap by hand. In this paper, a new approach is proposed for overlap detection in document images. Proposed method divides a document image into three parts: text, background, and image. Then text and image parts are processed to find overlap individually. After retrieving the text by means of OCR algorithm, it is modeled using signature extraction method. Jaccard index, cosine similarity, and Euclidean distance are applied for finding similar images. For segmenting document image, a novel approach based on blocking and neighborhood analysis is designed. Proposed method for overlap detection is capable of defeating technical disguise problem which exists in most plagiarism detection systems.
Variations in the quality of inpatient rehabilitation care to facilitate school re-entry and cognitive and communication function for children with TBI

Objective: To examine variations in processes of paediatric inpatient rehabilitation care related to school re-entry and management of cognitive and communication impairments after traumatic brain injury. Design: Retrospective cohort study. Methods: Adherence to care processes recommended for children (aged 0–17) with moderate-to-severe traumatic brain injury and admitted for inpatient rehabilitation was assessed. Quality-of-care indicators for processes supporting school re-entry and cognitive and communication rehabilitation were applied to measure variations in care delivered to 174 children across nine facilities using medical record review. Main outcomes and results: Adherence rates (the number of times recommended care was delivered or attempted divided by the number of times care was indicated) were calculated, revealing substantial variations in care within and between facilities. Overall, children received 51.3% (95% CI = 31.9–70.7) and 72.3% (95% CI = 61.1–83.5), of the care recommended for school re-entry and cognitive and communication rehabilitation, respectively. Conclusion: Substantial variations exist in the delivery of paediatric inpatient rehabilitation care processes for managing school re-entry and cognitive and communication impairments after traumatic brain injury. Measures of association of these care processes with patient outcomes are necessary. Reduction in this variation is essential to improving quality of care.
