Chromosome 1p31.1 Deletion Syndrome: Limited Expression

Chromosomal microdeletion syndromes usually present with neurological abnormalities, developmental delays, and various systemic abnormalities. 1p31 microdeletion syndrome is one of the novel microdeletion syndromes that usually presents with developmental delay, intellectual disability, various craniofacial abnormalities, and other systemic abnormalities in a proportion of cases. NEGR1 and NFIA are few of the genes present in this locus responsible for these symptoms. However, none of the reported cases had only isolated intellectual disability. Here, we are reporting a case of 1p31 microdeletion syndrome with isolated moderate intellectual disability and hyperactivity in an 11-year-old boy. It is essential for clinicians to be aware of such an atypical presentation of 1p31.1 microdeletion syndrome, to maintain reasonable clinical suspicion in cases with unexplained intellectual disability.
Spectrophotometric Determination of Enniatin a and Valinomycin in Fungal Extracts By Ion Complexation

Abstract When an ethylene dichloride solution of enniatin A is shaken with potassium picrate in potassium hydroxide solution, picrate anion is extracted into the organic phase in amount proportional to the enniatin concentration. Enniatin A can thus be determined spectrophotometrically in the range 5-60 μg/ml. Neutral lipids do not interfere. Valinomycin can be determined similarly, but cyclodepsipeptides that lack cationophoric properties are not estimated in this method.
Impact of material crystallization characteristics on the switching behavior of the phase change memory cell

The impact of material crystallization characteristics on the switching behavior of phase change memory cells has been investigated using finite element simulation. Both a conventional vertical cell and a horizontal line cell have been analyzed, using the widely used Ge 2 Sb 2 Te 5 (GST) which is a nucleation dominated material for the vertical cell, and Ag 5.5 In 6.5 Sb 59 Te 29 (AIST) which is a growth dominated material for the horizontal cell. Nucleation and growth models were implemented for both materials. Both RESET and SET program cycles were simulated. From these simulations, it was shown that the crystallization models gave realistic results for switching voltages, currents and switching times for the two different cell types. It is found that for GST, both nucleation (at lower voltages) and growth (at higher voltages) can play an important role in the crystallization. However, for AIST, crystal growth from non-amorphized crystal regions dominated over nucleation for all program conditions. The high growth rate of AIST moreover is shown to allow much shorter SET times in the line cell compared to that of GST in the vertical cell.
Widely tunable micro electromechanical systems (MEMS)-vertical-cavity surface-emitting lasers with single transverse mode operation

In this paper, a micro electromechanical systems vertical-cavity surface-emitting laser (MEMS-VCSEL) with asymmetric double oxide aperture and highly strained GaInNAsSb quantum wells for widely tunable, single mode and high temperature operation has been investigated. The MEMS-VCSEL is based on an integrated two-chip concept which allows us to extend the single wavelength performance to a continuously tunable, selectively wavelength-addressable spectrum of 40 nm. It has a much larger tuning range as compared with previous works. We present a comprehensive model including electrostatic membrane equation coupled with thermal, spatial and temporal rate equations considering Shockley Read Hall (SRH), Auger and carrier diffusion effects. These coupled equations are solved numerically by finite difference method (FDM). Using the simulation results, we design a single mode, high power, high temperature and tunable VCSEL, which is suitable for C-band dense-wavelength-division- multiplexing (DWDM) optical communication systems. Key words: Micro electromechanical systems (MEMS), tunable vertical-cavity surface-emitting laser (VCSELs), strained GaInNAsSb QWs, single mode operation.
Determination of Phenolic Compounds from Geranium sanguineum by HPLC

Abstract A high performance liquid chromatographic (HPLC) method has been developed for simultaneous determination of seventeen phenolic compounds (one phenolic acid, seven cinnamic acid derivatives, four quercetin glycosides, five flavonol, and flavone aglycones) from plant material. Separation of all examined compounds was carried out in 35 minutes on a Zorbax SB‐C18 analytical column (100×3.0 mm, 3.5 µm) with methanol‐KH2PO4 buffer (40 mM, pH 2.3) as mobile phase in a linear gradient. The linearity of calibration curves for all compounds was very good (R2>0.999). The detection limits for the determined compounds were in the range of 18.4 to 91.9 ng/mL. The method was successfully applied for the determination of phenolic compounds from Geranium sanguineum dried herb, the following phenolic compounds being identified: caftaric acid (1.30 mg/g), caffeic acid (2.41 mg/g), hyperoside (1.64 mg/g), isoquercitrin (2.58 mg/g), rutin (1.71 mg/g), quercitrin (0.42 mg/g), quercetin (0.82 mg/g), kaempferol (0.19 mg/g). After acid hydrolysis treatment of the plant material, when all glycosides were hydrolyzed to aglycones, the type of unidentified flavonoids present in Geranium sanguineum were determined as being kaempferol glycosides.
Information on Budgeting and Budgetary Allocation in Federal University Library, Lafia, Nasarawa State - Nigeria

This project research titled “Information on budgetary allocation in Federal University Library, Lafia (FUL Lafia)” was undertaken to ascertain the level of budgetary allocation and implementation in aiding library services in the institution. The methodology used in the study was the survey which adopted the descriptive sampling of 20 library staffs sampled for the study. The Questionnaire was constructed where each of the items in the questionnaire was grouped in accordance with their relationship to the research questions and analyzed using frequency distribution tables. The findings revealed that the extent of use of these budgetary systems in FUL Lafia is very high as library operations depends highly on proper budgetary allocation. As revealed by the respondents, the budgetary allocation for FUL is adequate. Also it was found that the major challenge being faced in FUL is improper budgetary allocation of funds. The study concludes that practical application of budgeted funds through proper budgetary allocation and implementation will go a long way in providing and equipping students with basic knowledge and competencies necessary for improved academic performance. Subsequently, the study recommends that the budgetary systems and processes being employed by the university authorities should be reviewed and improved upon so as to checkmate excesses and budget padding. In view of the challenges encountered in the budgetary allocation, it is recommended that qualified librarian, auditors and account experts be employed and the necessary tools needed for proper budgetary allocation be made available to them so as to curtail these challenges.

A Distance-Based Scheme for Reducing Bandwidth in Distributed Geometric Monitoring

Tracking the value of a function computed from a dynamic, distributed data stream is a challenging problem with many real-world applications. Continuously forwarding data updates can be costly, yet complex functions are difficult to evaluate when data is not centralized. One general approach to continuous distributed monitoring is the Geometric Monitoring (GM) family of techniques. GM reduces the functional monitoring problem to a set of local constraints that each node checks locally, and uses a simple protocol to update those constraints as needed.While most work on GM focuses on reducing the number of messages exchanged by the common GM protocol, with one recent notable exception, there has been little attention to reducing the size of those messages, which impacts bandwidth.We propose the Distance Scheme: a novel bandwidth-efficient variation of the GM protocol that reduces the size of most monitoring messages in GM to a single scalar, and is compatible with the large body of prior work on GM. We apply it to monitor three different functions using three real-world datasets, and show it substantially reduces bandwidth while requiring fewer messages to be transmitted than the current state-of-the-art approach. We further describe a value-based scheme that, while typically outperformed by the Distance Scheme, is simpler to apply, matches state-of-the-art bandwidth performance with fewer messages, and is also compatible with existing work.
Comparison of the Effects of Static-Stretching and Tubing Exercises on Acute Shoulder Range of Motion in Collegiate Baseball Players

Background The overhead throwing motion repetitively stresses the dominant arm in baseball players, frequently altering normal range of motion (ROM) in multiple directions. Baseball players regularly perform a combination of static stretches (SS) and dynamic tubing (DT) resistance exercises in pre-throwing warm-up routines intended to improve shoulder ROM and reduce injuries. Purpose The purpose of this study was to compare acute changes in dominant shoulder ROM improvements between SS and DT warm-up exercise protocols. The DT exercises were hypothesized to elicit greater improvements in shoulder ROM. Study Design Two-way crossover study. Methods Twenty-five healthy collegiate baseball players (mean age = 19.8 ±1.0 years) presenting with glenohumeral internal rotation deficit (GIRD) >20° and total rotational range of motion (TRROM) losses >5° completed the SS and DT interventions on different days. Dominant arm internal rotation (IR), external rotation (ER) and TRROM were measured before, immediately after, 30-minutes after, and 60-minutes after each treatment session. A two-way repeated measures analysis of variance (ANOVA) compared the effect of SS and DT over time on IR, ER and TRROM. Results IR improved on average 10.68 ± 0.82° (p < .001) post intervention, 11.18 ± 0.79° (p < .001) 30-min post intervention, and 9.03 ± 0.95° (p < .001) 60-min post intervention. ER improved on average 8.60 ± 0.67° (p < .001) post intervention, 8.25 ± 0.85° (p < .001) 30-min post intervention, and 6.65 ± 0.91° (p < .001) 60-min post intervention. TRROM improved on average 19.28 ± 1.09° (p < .001) post intervention, 19.43 ± 1.36° (p < .001) 30-min post intervention, and 15.68 ± 1.55° (p < .001) 60-min post intervention. There were no significant differences between the main effects of treatment and time for IR, ER, and TRROM. For IR, SS improved by an average of 1.73 ± 0.55° (p = .005) more than DT. For ER and TRROM, there were no differences between SS and DT. Conclusion Both SS and DT exercises improve glenohumeral IR, ER and TRROM up to one-hour post intervention, with no significant differences noted between interventions for treatment or time. Baseball players can benefit equally from performing SS or DT exercises to acutely improve shoulder ROM. Level of Evidence Level 3
Exploring the Historical Context of Graphic Symbols: the NOTAE Knowledge Graph and its Visual Interface

Graphic symbols i.e. graphic entities drawn as a visual unit in a written text and representing something other or something more than a word of that text are the research object of the NOTAE project, which investigates them in the documentary practice of the late Roman State and Post-Roman Kingdoms (400-800 AD). While research results from the project are stored by filling forms resulting from the analysis of ancient documents, we argue that the availability of a navigable knowledge graph can ease the work of researchers at finding non trivial implications in data. In this paper, we propose a first version of the NOTAE Knowledge Graph, and we outline future works and possible synergies.
Intercepting biological messages: Antibacterial molecules targeting nucleic acids during interbacterial conflicts

Abstract Bacteria live in polymicrobial communities and constantly compete for resources. These organisms have evolved an array of antibacterial weapons to inhibit the growth or kill competitors. The arsenal comprises antibiotics, bacteriocins, and contact-dependent effectors that are either secreted in the medium or directly translocated into target cells. During bacterial antagonistic encounters, several cellular components important for life become a weak spot prone to an attack. Nucleic acids and the machinery responsible for their synthesis are well conserved across the tree of life. These molecules are part of the information flow in the central dogma of molecular biology and mediate long- and short-term storage for genetic information. The aim of this review is to summarize the diversity of antibacterial molecules that target nucleic acids during antagonistic interbacterial encounters and discuss their potential to promote the emergence antibiotic resistance.
A Heuristic Algorithm for Multi-Agent Vehicle Routing with Automated Negotiation

We investigate a problem that lies at the intersection of three research areas, namely Automated Negotiation, Vehicle Routing, and Multi-Objective Optimization. Specifically, we investigate the scenario that multiple competing logistics companies aim to cooperate by delivering truck loads for one another, in order to improve efficiency and reduce the distance they drive. In order to do so, these companies need to find ways to exchange their truck loads such that each of them individually benefits. We present a new heuristic algorithm that, given one set of orders to deliver for each company, tries to find the set of all order-exchanges that are Pareto-optimal and individually rational. Furthermore, we present experiments based on real-world test data from two major logistics companies, which show that our algorithm is able to find hundreds of solutions in a matter of minutes.
PREDICTING EXTRUSION PROCESS PARAMETERS IN NIGERIA CABLE INDUSTRY FOR POLYETHYLENE CABLE INSULATION USING ARTIFICIAL NEURAL NETWORK

In order to obtain quality cable products in the thermoplastic extrusion process, it is important that during the polymer extrusion process, a melt that is homogenous in both temperature and composition is delivered. To achieve this, it is important to control, monitor, identify and select the important parameters during the extrusion process which directly impacts the product output. Some of these parameters include the melt pressure, temperature, line speed, screw speed, amongst others. In developing countries, however, these parameters are often selected on a trial and error basis which often leads to waste of material and the production of poor quality cables. This paper focuses on a technique which can be used to predict realistic extrusion process parameters for medium to high voltage cable insulations using artificial neural network. Real life datasets for the extrusion of Polyethylene (PE) thermoplastic were obtained and a three-layered feed-forward neural network as developed in the MATLAB environment. The neural network model developed can predict the manufacturing extrusion process parameters for different grades of PE thermoplastic which is used for medium to high voltage electrical cable insulation. A regression value of 0.99569 was obtained and a mean square error of 2.98052 (cid:3400) 10 (cid:2879)(cid:2874) was achieved.
s-AWARE: Using Crowd Judgements in Supervised Measure-Based Methods for IR Evaluation

Crowdsourcing methodologies have recently emerged as a cheap and fast alternative to the traditional document assessment process for ground truth creation. Early approaches make use of voting and/or classiﬁcation methodologies to combine crowd judgements into a merged pool, used as reference in the evaluation process. A measure-based approach has instead been used in Assessor-driven Weighted Averages for Retrieval Evaluation (AWARE) [3], focusing in optimizing the ﬁnal evaluation measure without merging judgements at pool level. s-AWARE extends AWARE with a set of supervised methods. We rely on several TREC collections to evaluate s-AWARE and we show that it outperforms state-of-the-art methods. Moreover, our results show that when moving to the real case scenario where a crowd-assessor only judges a portion of the dataset, s-AWARE is quite an eﬀective approach.
Complexation of tungsten(VI) with citrate

Complex formation between tungstate and citrate (citric acid, H4cit = 3-carboxy-3-hydroxypentane-1,5-dioic acid) has been investigated in the pHc range 1.5–9.5 by potentiometric and enthalpimetric titrations at 25 °C in 1.0 mol dm–3 NaCl. The potentiometric data were treated with the computer program SUPERQUAD taking into account side reactions of tungstate and citrate with hydrogen ions. The ‘best’ reaction model comprises eight complexes, representing four different tungstate–citrate stoichiometries. The formation constants of the complexes, denoted by βpqr, where the subscripts p, q and r refer to the stoichiometric coefficients in the general formula [(WO4)p(Hcit)qHr](2p+3q-r)–, have the values log β111= 10.21, log β112= 17.03, log β113= 21.67, log β114= 22.82, log β224= 34.89, log β225= 39.3, log β126= 34.51 and log β214= 31.7. Enthalpy and entropy changes for the complexation reactions were calculated from the calorimetric data using the values of these formation constants. The enthalpy values for the major complexes are ΔH°111=–66, ΔH°112=–67 and ΔH°113=–78 kJ mol–1.
Bulk and Surface Properties of Copper-Containing Oxides of the General Formula LaZr1-xCuxO3

Abstract Compounds of nominal composition LaZr1-xCuxO3 (0 ≤ X ≤ 1) have been prepared by thermal decomposition in air of precursors prepared by the amorphous citrate method. X-ray diffraction has been used to determine the phases present in the material following calcination at 973 K and following calcination and reduction at 973 K. X-ray photoelectron spectroscopy (XPS) was used to obtain information regarding electronic state and concentration of elements in the surface layers, while thermal gravimetric (TG) studies in hydrogen indicate the relative stability of copper species towards reduction. For all values of X except 1, the pyrochlore phase, La2Zr2O7 was obtained. CuO was detected for all values of X greater than 0, whereas LaCnO3 and La2CuO4 were only detected for values of X > 0.3. These phases containing copper were reduced within the temperature range 350-800 K, leading to formation of metallic copper and La(OH)3 and La2O3.
Interactions between poly(ethylene oxide)-based surfactants and transition metal alkoxides: their role in the templated construction of mesostructured hybrid organic–inorganic composites

The interactions between PEO-based templates and metallic centres are key in the synthesis of mesostructured materials. In low-water-content media, strong chelation between metal centres and the non-ionic polar heads leads to polymer unfolding, and thus to worm-like phases. Larger quantities of water and acid added to the reaction bath weaken the coordination bonds that compose the hybrid interface. These resulting weak interactions (mainly hydrogen bonding) help the folding of the templating agents, and yield more ordered mesophases.

Formation of Soap Films from Insoluble Surfactants

Abstract The formation of a single soap film from a liquid reservoir raises a question about the origin of the additional surfactant molecules needed to coat the newly created surface. We have thus studied films made from insoluble surfactants (sodium decanoate and sodium octanoate) and varied the pH to monitor the solubility and possibly the exchange of surfactants between surface and bulk. We show that there exists a pH range where the foaming is optimum; the film formation then obeys the Frankel law, but with some discrepancy at high pulling velocities that we may attribute to the breakage of the surfactant wall and the loss of elasticity.

A one-step, cost-effective green method to in situ fabricate Ni(OH)2 hexagonal platelets on Ni foam as binder-free supercapacitor electrode materials

Nickel hydroxide (Ni(OH)2) is considered to be a promising alternative to the expensive and toxic RuO2 electrode material for high-performance supercapacitors; however, the fabrication method and electrochemical performance of suitable Ni(OH)2 structures are unsatisfactory. In the present work, a facile, cost-effective green method is developed to in situ fabricate Ni(OH)2 hexagonal platelets on Ni foam as a binder-free supercapacitor electrode with high performance. The Ni(OH)2 hexagonal platelets are self-grown on three-dimensional (3D) Ni foam by a one-step hydrothermal treatment of Ni foam in a 15 wt% H2O2 aqueous solution without the use of nickel salts, acids, bases, or post-treatments. The as-prepared Ni(OH)2 hexagonal platelets-Ni foam (HNF) electrode can be used directly as a supercapacitor electrode material, thereby avoiding the need for binders and conducting agents. The Ni(OH)2 hexagonal platelets demonstrate high capacitance (2534 F g−1 at a scan rate of 1 mV s−1) and excellent cycling stability (97% capacitance retention after 2000 cycles at a scan rate of 50 mV s−1). The fabrication method developed here has the significant advantage of low-cost, facile, green, and additive-free processing, and it is therefore a promising route for preparing self-supported metal (hydr)oxide electrodes for high-performance supercapacitors and other energy-storage devices.
Stereoselective synthesis of (Z)‐5‐(Trideca‐4‐enyl)resorcinol and gibbilimbols A—D

(Z)-5–(Trideca-4-enyl)resorcinol (1) and gibbilimbols A—D (2–5) were synthesized in 47%-60% yields over 6 steps from commercially available starting materials. The Wittig reaction of various alkyl phosphonium bromides with appropriate aldehydes in the presence of potassium ten-butoxide (t-BuOK) in anhydrous THF solution at room temperature served as the key step, and the result showed that only (Z)-configuration olefins were formed by this procedure. The synthesis of the (Z)-5-(trideca-4-enyl)resorcinol (1) was reported for the first time.
