For calculation of semantic similarity measures between GO terms, REVIGO relies on pre-computed information content (IC) for the GO terms. The IC is calculated as a negative logarithm of the GO term's relative frequency in a reference database – the EBI GOA database [20] (link) – which annotates all UniProt entries with GO terms. The user may optionally decide to select the database with one of the 11 species-specific GOA subsets for common model organisms, in order to fine-tune the calculation of semantic distances (which rely on IC) for the problem at hand. If the particular organism is not offered in REVIGO, the closest available organism or the default UniProt database should generally be adequate replacements, assuming that the relative frequencies of gene functions in the user's genome are not far from the ones in the selected genome, or in case UniProt was selected, from the overall trends in the genomic databases.
REVIGO supports four semantic similarity measures based on the concept of the “most informative common ancestor”: Lin's, Resnik's, Jiang and Conrath's measures, and the SimRel measure [8] (link). These and other measures and the role of the IC in their calculation are reviewed in [12] (link). The employed semantic similarity measures are quite robust with regard to future changes in the EBI GOA database due to new or updated annotations, as they don't rely on the GO annotations of each particular gene, but only on the terms' overall IC, which is expected to change little with time. Therefore, an aggressive update schedule is not necessary for REVIGO, and the underlying Gene Ontology and the EBI GOA database will normally be updated on a yearly basis, and more frequently in case of a large-scale release of new GO terms by the GO Consortium.
REVIGO also has a facility for integration with Web servers/software which produce lists of GO categories, typically by testing for statistically significant enrichment of a variable in GO terms; see

When comparing two gene clusters, another original feature of ClueGO allows to switch the visualization of the groups on the network to the cluster distribution over the terms. Besides the network, ClueGO provides overview charts showing the groups and their leading term as well as detailed term histograms for both, cluster specific and common terms.
Like BiNGO, ClueGO can be used in conjuntion with GOlorize for functional analysis of a Cytoscape gene network. The created networks, charts and analysis results can be saved as project in a specified folder and used for further analysis.

MR‐Egger regression additionally provides an estimate for the true causal effect
In order to select labels from the pool for the new levels, an interviewer-administered response scaling exercise similar to those used in previous studies [14 (link), 19 , 20 (link)] was adopted to estimate the severity represented by each label. For this exercise, respondents were shown a rating scale in the form of a vertical, hash-marked, 40 cm visual analog scale (VAS) with end points of 0 and 100 to be used as a visual aid in grading label severity. For the Mobility, Self-Care and Usual Activities dimensions, the same set of labels was used. The interviewer placed a card labeled ‘No problems’, ‘No pain/discomfort’, or ‘No anxiety/depression’ as appropriate at the bottom of the scale (0) to act as the lower anchor and a card labeled ‘Unable to, ‘The worst pain or discomfort I can imagine’, ‘As anxious or depressed as I can imagine’ as the upper anchor (100). The respondent was then shown other labels from the pool singly in a quasi-random order and asked to assign a score between 0 and 100 to indicate label severity in relation to the lower and upper anchors.
The interviewer noted all scores, and when the respondent had rated all labels for a particular dimension, the interviewer laid them out in rank order alongside the VAS and asked the respondent to review the ranking and make any changes he or she thought necessary. If labels were reordered at this point, the respondent was asked to assign a new score to the relevant labels. Final scores assigned were recorded in an answer booklet. The scaling task was repeated for each dimension. Before finishing with the cards, the respondent was asked whether any of the labels sounded unusual, or should not be used in relation to a particular dimension.
Respondents rated labels for all five dimensions. The three functional dimensions (Mobility, Self-Care and Usual Activities) were always interspersed by the Pain/Discomfort and Anxiety/Depression dimensions, so that the respondent did not rate the same label types consecutively. Before rating the actual labels, respondents performed a practice task based on levels of overall health to get used to the study requirements. Data on age, level of education, main activity, and use of any current treatment for health problems, together with the existing EQ-5D-3L descriptive system and EQ-VAS, were collected after the response scaling task.
Before the main response scaling task, a pilot test was performed to test study procedures and materials. Based on the results of the pilot study, some labels were eliminated from the initial pool to achieve a more manageable number for the response scaling task. In particular, any labels using additional modifiers such as ‘very’ or ‘quite’ were eliminated as were any that were considered excessively colloquial or too high a level of language. After pilot testing, it was concluded that the feasible limit was about 10–12 labels per dimension for an individual respondent.
Responses to the scaling task were analyzed by calculating means and medians and the corresponding standard deviations and interquartile ranges (IQR). Labels to go forward for further testing were selected based on criteria that had been identified before data collection started. These included selecting labels close to or at the 25th, 50th, and 75th centiles on the VAS, ensuring consistency across dimensions and coherence with wording in the descriptive system. No quantitative comparison of label scores was carried out in deciding which labels to carry forward to the next stage; median scores were simply used as a guide to determine which labels fell closest to the 25th, 50th, and 75th centiles. Labels were also required to be in colloquial language. The choice of labels and their appropriateness was discussed by the task force at several meetings during the course of the study.

Example 2
As discussed herein above, the disclosed methods improve the antiseptic properties of a dental implant without using charged metallic ions via conversion of the nitrogen moieties in titanium nitride surface to a positively charged quaternary ammonium via a Menschutkin reaction.
To prepare the antibacterial quaternized TiN surface, an implant which has been coated with TiN was used. The implant was cleaned to improve yield. The implant was washed with two solvents in sequence, acetone and isopropanol, to remove any dust particulate and other residue. The native oxide layer was removed by sonicating in 1:10 HCl:deionized water for 1 minute. This treatment additionally removes any residue that may not have been removed by the solvents. Acetonitrile was used as the solvent; however, any solvent may be used with preference for polar solvents giving improved reaction times (Stanger K., et al. J Org Chem. 2007 72(25):9663-8; Harfenist M., et al. J Am Chem Soc 1957 79(16):4356-4358). An excess of allyl bromide was added to the solvent and continuously stirred. The sample was then submerged in the solution, and full reaction of the surface occurred within about 60 minutes, as confirmed by contact angle measurement. A reference was also measured by submerging in solvent for the duration with no reactant to ensure any changes in surface properties was due to the quaternization.
Without wishing to be bound by a particular theory, the increased hydrophobicity of the treated surfaces can be due to the presence of the allyl groups on the surface which will impart some hydrophobicity. The contact angle measurements provide information on whether or not a reaction has occurred and whether it has saturated.
The biocidal activity was tested using live bacteria cultures from a patient's mouth, which provides the full flora to act against rather than targeting an individual strain of bacteria. The bacteria was incubated on the sample surface using several bacteria film thicknesses. The thickness is defined by keeping the same interaction surface area while varying the volume of bacteria solution added. Across two separate patients and several separate growths, within 4 hours 40-50% reduction in bacteria unit counts were observed for quaternized TiN as compared to traditional Titanium implants, outperforming traditional TiN coatings.
Unless defined otherwise, all technical and scientific terms used herein have the same meanings as commonly understood by one of skill in the art to which the disclosed invention belongs. Publications cited herein and the materials for which they are cited are specifically incorporated by reference.
It will be apparent to those skilled in the art that various modifications and variations can be made in the present disclosure without departing from the scope or spirit of the disclosure. Other aspects of the disclosure will be apparent to those skilled in the art from consideration of the specification and practice of the disclosure disclosed herein. It is intended that the specification and examples be considered as exemplary only, with a true scope and spirit of the disclosure being indicated by the following claims.
Example 1
95 g of manganese (purity: 99.95%; purchased from Taewon Scientific Co., Ltd.) and 5 g of high-purity graphite (purity: 99.5%; purchased from Taewon Scientific Co., Ltd.) were placed in a water-cooled copper crucible of an argon plasma arc melting apparatus (manufactured by Labold AG, Germany, Model: vacuum arc melting furnace Model LK6/45), and melted at 2,000 K under an argon atmosphere. The melt was cooled to room temperature at a cooling rate of 104 K/min to obtain an alloy ingot. The alloy ingot was crushed to a particle size of 1 mm or less by hand grinding. Thereafter, the obtained powders were magnetically separated using a Nd-based magnet to remove impurities repeatedly, and the Mn4C magnetic powders were collected. The collected Mn4C magnetic powders were subjected to X-ray diffraction (XRD) analysis (measurement system: D/MAX-2500 V/PO, Rigaku; measurement condition: Cu—Kα ray) and energy-dispersive X-ray spectroscopy (EDS) using FE-SEM (Field Emission Scanning Electron Microscope, MIRA3 LM).
As can be seen in
The M-T curve of the field aligned Mn4C powder obtained in Example 1 was measured under an applied field of 4 T and at a temperature ranging from 50 K to 400 K. Meanwhile, the M-T curve of the randomly oriented Mn4C powder was measured under an applied field of 1 T. The Curie temperature of Mn4C was measured under 10 mT while decreasing temperature from 930 K at a rate of 20 K/min.
According to the Néel theory, the ferrimagnets that contain nonequivalent substructures of magnetic ions may have a number of unusual forms of M-T curves below the Curie temperature, depending on the distribution of magnetic ions between the substructures and on the relative value of the molecular field coefficients. The anomalous M-T curves of Mn4C, as shown in
According to one embodiment of the present disclosure, the saturation magnetization of Mn4C increases linearly with increasing temperature within the range of 50 K to 590 K and remains stable at temperatures below 50 K. The increases in anomalous magnetization of Mn4C with increasing temperature can be considered in terms of the Néel's P-type ferrimagnetism. At temperatures above 590 K, the Mn4C decomposes into Mn23C6 and Mn, which are partially oxidized into the manganosite when exposed to air. The remanent magnetization of Mn4C varies little with temperature. The Curie temperature of Mn4C is about 870 K. The positive temperature coefficient (about 0.0072 Am2/kgK) of magnetization in Mn4C is potentially important in controlling the thermodynamics of magnetization in magnetic materials.
The Curie temperature Te of Mn4C is measured to be about 870 K, as shown in
As shown in
The magnetic properties of Mn4C measured are different from the previous theoretical results. A corner MnI moment of 3.85μB antiparallel to three face-centered MnII moments of 1.23μB in Mn4C was expected at 77 K. The net moment per unit cell was estimated to be 0.16μB. In the above experiment, the net moment in pure Mn4C at 77 K is 0.26μB/unit cell, which is much larger than that expected by Takei et al. It was reported that the total magnetic moment of Mn4C was calculated to be about 1μB, which is almost four times larger than the 0.258μB per unit cell measured at 4.2 K, as shown in
The thermomagnetic behaviors of Mn4C are related to the variation in the lattice parameters of Mn4C with temperature. It is known that the distance of near-neighbor manganese atoms plays an important role in the antiferro- or ferro-magnetic configurations of Mn atoms. Ferromagnetic coupling of Mn atoms is possible only when the Mn—Mn distance is large enough.
Thus, it can be seen that the abnormal increase in magnetization of Mn4C with increasing temperature occurs due to the variation in the lattice parameters of Mn4C with temperature.
The powder produced in Example 1 was annealed in vacuum for 1 hour at each of 700 K and 923 K, and then subjected to X-ray spectroscopy, and the results thereof are shown in
The magnetization reduction of Mn4C at temperatures above 590 K is ascribed to the decomposition of Mn4C, which is proved by the XRD patterns of the powders after annealing Mn4C at elevated temperatures.
These results prove that the metastable Mn4C decomposes into stable Mn23C6 at temperatures above 590 K. The presence of Mn4C in the powder annealed at 923 K indicates a limited decomposition rate of Mn4C, from which the Tc of Mn4C can be measured. Both Mn23C6 and Mn are weak paramagnets at ambient temperature and elevated temperatures. Therefore, the magnetic transition of the Mn4C magnetic material at 870 K is ascribed to the Curie point of the ferrimagnetic Mn4C.
The Mn4C shows a constant magnetization of 0.258μB per unit cell below 50 K and a linear increment of magnetization with increasing temperature within the range of 50 K to 590 K, above which Mn23C6 precipitates from Mn4C. The anomalous M-T curves of Mn4C can be considered in terms of the Néel's P-type ferrimagnetism.

Unless specifically stated otherwise as apparent from the foregoing disclosure, it is appreciated that, throughout the foregoing disclosure, discussions using terms such as “processing,” “computing,” “calculating,” “determining,” “displaying,” or the like, refer to the action and processes of a computer system, or similar electronic computing device, that manipulates and transforms data represented as physical (electronic) quantities within the computer system's registers and memories into other data similarly represented as physical quantities within the computer system memories or registers or other such information storage, transmission or display devices.
One or more components may be referred to herein as “configured to,” “configurable to,” “operable/operative to,” “adapted/adaptable,” “able to,” “conformable/conformed to,” etc. Those skilled in the art will recognize that “configured to” can generally encompass active-state components and/or inactive-state components and/or standby-state components, unless context requires otherwise.
The terms “proximal” and “distal” are used herein with reference to a clinician manipulating the handle portion of the surgical instrument. The term “proximal” refers to the portion closest to the clinician and the term “distal” refers to the portion located away from the clinician. It will be further appreciated that, for convenience and clarity, spatial terms such as “vertical”, “horizontal”, “up”, and “down” may be used herein with respect to the drawings. However, surgical instruments are used in many orientations and positions, and these terms are not intended to be limiting and/or absolute.
Those skilled in the art will recognize that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to claims containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations.
In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that typically a disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms unless context dictates otherwise. For example, the phrase “A or B” will be typically understood to include the possibilities of “A” or “B” or “A and B.”
With respect to the appended claims, those skilled in the art will appreciate that recited operations therein may generally be performed in any order. Also, although various operational flow diagrams are presented in a sequence(s), it should be understood that the various operations may be performed in other orders than those which are illustrated, or may be performed concurrently. Examples of such alternate orderings may include overlapping, interleaved, interrupted, reordered, incremental, preparatory, supplemental, simultaneous, reverse, or other variant orderings, unless context dictates otherwise. Furthermore, terms like “responsive to,” “related to,” or other past-tense adjectives are generally not intended to exclude such variants, unless context dictates otherwise.
It is worthy to note that any reference to “one aspect,” “an aspect,” “an exemplification,” “one exemplification,” and the like means that a particular feature, structure, or characteristic described in connection with the aspect is included in at least one aspect. Thus, appearances of the phrases “in one aspect,” “in an aspect,” “in an exemplification,” and “in one exemplification” in various places throughout the specification are not necessarily all referring to the same aspect. Furthermore, the particular features, structures or characteristics may be combined in any suitable manner in one or more aspects.
Any patent application, patent, non-patent publication, or other disclosure material referred to in this specification and/or listed in any Application Data Sheet is incorporated by reference herein, to the extent that the incorporated materials is not inconsistent herewith. As such, and to the extent necessary, the disclosure as explicitly set forth herein supersedes any conflicting material incorporated herein by reference. Any material, or portion thereof, that is said to be incorporated by reference herein, but which conflicts with existing definitions, statements, or other disclosure material set forth herein will only be incorporated to the extent that no conflict arises between that incorporated material and the existing disclosure material.
In summary, numerous benefits have been described which result from employing the concepts described herein. The foregoing description of the one or more forms has been presented for purposes of illustration and description. It is not intended to be exhaustive or limiting to the precise form disclosed. Modifications or variations are possible in light of the above teachings. The one or more forms were chosen and described in order to illustrate principles and practical application to thereby enable one of ordinary skill in the art to utilize the various forms and with various modifications as are suited to the particular use contemplated. It is intended that the claims submitted herewith define the overall scope.
Example 8
An adhesive layer (product name: OCA #8146 from 3M company) was interposed between the prepared film and a PET substrate to obtain a multilayer film. It was folded to have a radius of curvature of 3 mm, which was left at a low temperature of −20° C. for 72 hours, and then unfolded. The extent of wrinkles was visually observed. In such event, if no wrinkles were visually observed, it was evaluated as o. If wrinkles were visually observed slightly, it was evaluated as Δ. If wrinkles were visually observed readily, it was evaluated as x.
As can be seen from Table 1 above, the polyamide-imide films of Examples 1a to 4a had an MOR value of 75% or more. Thus, they maintained the modulus at least at a certain level even under the harsh conditions of high temperatures.
Since the display device is an electronic device, it generates heat during its use and it is to be used in a hot place as well, it is essential to secure mechanical properties at least at a certain level at high temperatures. Specifically, when a film is applied to a cover window for a display device, if the MOR value is 75% or more, no problem arises when a display device is fabricated.
In addition, the polyamide-imide films of Examples 1a to 4a were all excellent in the TSR value, ELR value, MO1a value, TS1a value, EL1a value, MO2a value, TS2a value, and EL2a value, in addition to the MOR value. That is, the polymer films of Examples 1a to 4a had high mechanical properties such as tensile strength, elongation at break, and modulus at room temperature and maintained the excellent mechanical properties even after the treatment under the severe conditions of high temperatures for a certain period of time.
Further, the polyamide-imide films of Examples 1a to 4a were all excellent in the evaluation of flexural resistance.
In contrast, since the films of Comparative Examples 1a to 3a had a low MOR value of 72% or less, when the film is applied to cover window for display device, it would have defects in appearance stability. In addition, the films of Comparative Examples 1a and 2a failed in the evaluation of flexural resistance. Thus, they are unsuitable for application to foldable display device or flexible display device.
As can be seen from Table 2 above, the polyamide-imide films of Examples 1b to 8b had a dMO value of 1% to 8%. Thus, they maintained the modulus at least at a certain level even under the harsh conditions of low temperatures.
In the case where the polyamide-imide film is applied to a cover window for a display device and to a display device, it may be used in an extremely cold environment. Thus, it is essential to secure mechanical properties at least at a certain level even in such an extremely cold environment. Specifically, when the polyamide-imide film is applied to a cover window for a display device and to a display device, if the dMO value is within 1% to 8%, no problem arises.
In addition, the polyamide-imide films of Examples 1b to 8b were all excellent in the dTS value, dEL value, MO1b value, TS1b value, EL1b value, MO2b value, TS2b value, and EL2b value, in addition to the dMO value. That is, the polymer films of Examples 1b to 8b had high mechanical properties such as tensile strength, elongation at break, and modulus at room temperature and maintained the excellent mechanical properties even after the treatment under the severe conditions of low temperatures for a certain period of time.
Further, the polyamide-imide films of Examples 1b to 8b were all excellent in the folding characteristics at low temperatures.
In contrast, since the films of Comparative Examples 1b and 2b had a low dMO value of 1% or less, when it is applied to a cover window for a display device, it would not be balanced with other layers, resulting in cracks, which is defective in terms of the appearance stability. In addition, the films of Comparative Examples 1b and 2b failed in the evaluation of flexural resistance at low temperatures. Thus, they are unsuitable for application to a foldable display device or a flexible display device.
Example 1
The target organoselenium compound 5 is synthesized using the Ugi four components reaction. The synthesis starts by the reaction of quinazoline-2-carbaldehyde (1) (1 mmol) with 4-(methylselanyl)aniline (2) (1 mmol) followed by the addition of 2-((3-methyl-1,4-dioxo-1,4-dihydronaphthalen-2-yl)thio)acetic acid (3) (1 mmol) and 2-isocyano-2-methylpropane (4) (1.2 mmol). The reaction proceeds smoothly at room temperature in methanol as solvent.
It is to be understood that the organic selenide compounds and the use thereof with DPPD are not limited to the specific embodiments described above, but encompasses any and all embodiments within the scope of the generic language of the following claims enabled by the embodiments described herein, or otherwise shown in the drawings or described above in terms sufficient to enable one of ordinary skill in the art to make and use the claimed subject matter.
