The ABC1 (ABCA) subfamily of the ATP-binding cassette (ABC) transporter superfamily has a structural feature that distinguishes it from other ABC transporters. Here we report the cloning, molecular characterization and tissue distribution of ABC2/ABCA2, which belongs to the ABC1 subfamily. Rat ABC2 is a protein of 2434 amino acids that has 44.5%, 40.0% and 40.8% identity with mouse ABC1/ABCA1, human ABC3/ABCA3 and human ABCR/ABCA4 respectively. Immunoblot analysis showed that proteins of 260 and 250kDa were detected in COS-1 cells transfected with ABC2 having a haemagglutinin tag, while no band was detected in mock-transfected cells. After incubation with N-glycosidase F, the mobilities of the two proteins increased and a single band was detected, suggesting that ABC2 is a glycoprotein. Photoaffinity labelling with 8-azido-[α-32P]ATP confirmed that ATP binds to the ABC2 protein in the presence of Mg2+. RNA blot analysis showed that ABC2 mRNA is most abundant in rat brain. Examination of brain by in situ hybridization determined that ABC2 is expressed at high levels in the white matter, indicating that it is expressed in the oligodendrocytes. ABC2, therefore, is a glycosylated ABC transporter protein, and may play an especially important role in the brain. In addition, the N-terminal 60-amino-acid sequence of the human ABC1, which was missing from previous reports, has been determined.

ABB Industries was told to implement activity-based costing (ABC) for costing in their consolidated reports sent to ABB Group, their parent firm. To meet this need, they chose to implement ABC using SAP's R/3. For two of nine product lines, parallel ABC was developed. Unfortunately, the version of ABC needed to generate financial statements, operational ABC, would not be available until a later release of the software. While ABB Industries waits for the next release, key personnel associated with the implementation are being offered alternative internal and external opportunities. Further, in order for ABB Industries to implement the operational ABC, the entire firm must implement a new version of SAP's R/3.

AbstractOne important mechanism suggested to underlie the acquisition of grammar is rule learning. Indeed, infants aged 0 ; 7 are able to learn rules based on simple identity relations (adjacent repetitions, ABB: “wo fe fe” and non-adjacent repetitions, ABA: “wo fe wo”, respectively; Marcus et al., 1999). One unexplored issue is whether young infants are able to process both adjacent and non-adjacent repetitions. As the previous studies always compared the two types of repetition structures directly, the ability to learn only one of them was sufficient for successful discrimination in these tasks. The present study reports two experiments, in which we test the ability of infants aged 0 ; 7 to discriminate adjacent and non-adjacent repetition structures against random controls (ABB vs. ABC and ABA vs. ABC). We show that, contrary to some previous proposals, infants aged 0 ; 7 successfully discriminate both repetition types from random controls, but show no spontaneous preference for either of them.

Audio media “ABC” (Aku Baca dalam Cerita) a learning media that introduces letters through stories for Early Childhood Education aged 5-6 years. To find out the success of the media, it is necessary to evaluate: Is ABC audio media can help introduce alphabet on early childhood learners? How the level of development of the language aspects of students after learning with ABC audio media? Evaluation of the use of audio media ABC aims to know the audio media ABC in introducing letters to students in early childhood and to determine the development of language students with learning ABC audio media. This research was conducted for 10 days on 1-14 August 2017 in ABA Gamping TK, Sleman, Yogyakarta. The population of this research is all of ABA Gamping TK students with the sample of 40 PAUD students. The results of this study obtained data that the level of developmental achievement of students aged 5-6 years in recognizing the letter pattern was good. Thus it can be seen that ABC learning audio media can help in introducing letters to students in early childhood. At the level of achievement of language development, it is shown that most students can achieve the predetermined indicators. This shows that ABC audio media can improve language development in early childhood education. However, there is still a need for variations in the presentation format in ABC learning audio media programs to stimulate the imagination of students in early childhood and the need for supporting materials that can stimulate the students' creativity.ABSTRAKMedia Audio “ABC” (Aku Baca dalam Cerita) merupakan media audio pembelajaran yang memperkenalkan huruf melalui cerita untuk Pendidikan Anak Usia Dini usia 5-6 tahun.

ZusammenfassungVom 2. bis 4. November 2017 fand in Lissabon unter Leitung von Frau Professor Fatima Cardoso die 4. Internationale Konsensuskonferenz ABC4 (Advanced Breast Cancer Forth Consensus) zu Diagnostik und Behandlung des fortgeschrittenen Mammakarzinoms (ABC) statt. Zur Vereinfachung wird im weiteren Text von ABC gesprochen, was im klinischen Alltag der metastasierten Brustkrebserkrankung oder der lokal weit fortgeschrittenen Erkrankung entspricht. Der inhaltliche Schwerpunkt lag dieses Jahr auf neuen Entwicklungen in der Behandlung des ABC. Diskutiert wurden unter anderem der Stellenwert der CDK4/6-Inhibition beim hormonrezeptor(HR-)positiven ABC, die duale Antikörperblockade beim HER2-positiven ABC, die PARP-Inhibition beim BRC-Amutierten tripel-negativen und luminalen ABC sowie potenzielle therapeutische Konsequenzen. Ein weiterer Fokus lag auf dem BRCA-assoziierten Mammakarzinom, der Behandlung von Hirnmetastasen sowie der individualisierten Therapieentscheidung auf der Grundlage einer molekularen Testung (sog. Präzisionsmedizin). Wie schon in den vergangenen Jahren ist die Zusammenarbeit mit den Vertretern von Patientenorganisationen aus aller Welt ein wichtiges Anliegen der ABC-Konferenz. Sie wurde auf der ABC4-Konferenz weiter intensiviert. Im Anschluss an die Konsensuskonferenz wurde die „Global Alliance“ gegründet mit dem Ziel, die erforderlichen Maßnahmen aus Sicht der Patientenvertreterinnen weltweit zu propagieren und zu koordinieren. In den ABC-Konsensus fließen aufgrund des international zusammengesetzten Expertenpanels zwangsläufig länderspezifische Besonderheiten ein. Wie schon in den vergangenen Jahren hat daher eine Arbeitsgruppe deutscher Brustkrebsexperten, die die Konsensusabstimmung der ABC-Panelisten vor Ort mitverfolgt und intensiv diskutiert haben, diese unter Berücksichtigung der deutschen Leitlinien zu Diagnostik und Therapie des Mammakarzinoms 1 2 für den Therapiealltag in Deutschland kommentiert. Die Abstimmungsergebnisse der ABC-Panelisten in Lissabon sind die Grundlage des ABC-Konsensus.

The Advanced Breast Cancer Third International Consensus Conference on the diagnosis and treatment of advanced breast cancer took place in Lisbon, Portugal, on November 5-7, 2015. This year's conference (ABC3) was focused on the treatment of metastatic breast cancer (stage IV), as it was 4 years ago at the first consensus meeting (ABC1). A matter of particular interest was the patients' perspective. Thus, patient-relevant issues were addressed by the consensus discussions, such as those on treatment goals, quality of life, care of long-term survivors (‘survivorship issues'), and coping with disease-related symptoms and the side effects of treatment. Further important issues on the agenda were the use of standardized instruments for the assessment of individual treatment success (‘patient-reported outcome measures') and the evaluation of the benefit of novel drugs (e.g. the European Society for Medical Oncology (ESMO) Magnitude of Clinical Benefit Scale). Diagnosis and treatment of inoperable locally advanced breast cancer had already been discussed 2 years earlier at the ABC2 Consensus and were not dealt with in the framework of this year's ABC3 Consensus. With regard to country-specific peculiarities, which unavoidably found their way into the ABC Consensus, a working group of German breast cancer experts commented on the voting results of the ABC panelists. As for the past consensus, the group specially considered the German guidelines for the diagnosis and treatment of breast cancer (AGO (Gyneco-Oncology Working Group), S3, DGHO (German Society of Hematology and Medical Oncology)) in order to adapt the ABC3 consensus for everyday therapy in Germany.

The Advanced Breast Cancer Fourth Consensus (ABC4) on diagnosis and treatment of advanced breast cancer (ABC) again took place in Lisbon, on November 2-4, 2017, and was chaired by Fatima Cardoso, MD, PhD. This year's contents focused very much on new developments in the treatment of ABC. For example, the significance of inhibition of cyclin-dependent kinases 4 and 6 (CDK4/6) in hormone receptor (HR)-positive ABC, of dual antibody blockade in human epidermal growth factor receptor 2 (HER2)-positive ABC, and of poly(ADP-ribose) polymerase (PARP) inhibition in triple-negative ABC, as well as the potential therapeutic consequences, were discussed. Other key issues were BRCA-associated breast cancer, treatment of brain metastases, and personalized therapy decision-making using molecular testing (so-called ‘precision medicine'). As in past years, an important objective of the ABC conference was cooperation with representatives of patient organizations from around the world. This cooperation was further intensified during the ABC4. Following the main conference, the ‘Global Alliance' was founded, with the goal of publicizing and coordinating measures necessary worldwide from the patient advocates' standpoint. - The ABC consensus inevitably cannot accommodate country-specific needs, due to the truly global expert panel. Therefore, a working group of German breast cancer experts commented - as in the past years - on the on-site voting results by the ABC panelists upon which the final ABC4 consensus will be based, with particular consideration of the German guidelines on diagnosis and treatment of breast cancer for everyday treatment in Germany.

Using a conditioned suppression preparation, we investigated extinction and aba-, abc-, and aab-renewal of Pavlovian modulation in human sequential Feature Positive (FP) discrimination learning, X → A+/A−. Extinction treatment was administered in the acquisition context a (aaa- and aab-groups) or in a new context b (aba- and abc-groups) and comprised X → A− extinction trials. Discriminative X → A/A responding was lost in all groups when tested in the extinction context. In the aba-group, the discriminative X → A/A responding totally recovered when retested in the acquisition context a. For the aaa-, the aab-, and the abc-group, discriminative X → A/A responding did not reappear when tested for renewal in, respectively, contexts a, b, and c. The demonstration of aba-renewal of extinguished modulation, but not abc- and aab-renewal, suggests that extinction in a context different from the acquisition context and a return to the original acquisition context might both be critical for renewal of Pavlovian modulation in human FP-discrimination learning.

AbstractThe fourth international advanced breast cancer consensus conference (ABC4) on the diagnosis and treatment of advanced breast cancer (ABC) headed by Professor Fatima Cardoso was once again held in Lisbon on November 2 – 4, 2017. To simplify matters, the abbreviation ABC will be used hereinafter in the text. In clinical practice, the abbreviation corresponds to metastatic breast cancer or locally far-advanced disease. This year the focus was on new developments in the treatment of ABC. Topics discussed included the importance of CDK4/6 inhibition in hormone receptor (HR)-positive ABC, the use of dual antibody blockade to treat HER2-positive ABC, PARP inhibition in triple-negative ABC and the potential therapeutic outcomes. Another major area discussed at the conference was BRCA-associated breast cancer, the treatment of cerebral metastasis, and individualized treatment decisions based on molecular testing (so-called precision medicine). As in previous years, close cooperation with representatives from patient organizations from around the world is an important aspect of the ABC conference. This cooperation was reinforced and expanded at the ABC4 conference. A global alliance was founded at the conclusion of the consensus conference, which aims to promote and coordinate the measures considered necessary by patient advocates worldwide. Because the panel of experts was composed of specialists from all over the world, it was inevitable that the ABC consensus also reflected country-specific features. As in previous years, a team of German breast cancer specialists who closely followed the consensus voting of the ABC panelists in Lisbon and intensively discussed the votes has therefore commented on the consensus in the context of the current German guidelines on the diagnosis and treatment of breast cancer 1, 2 used in clinical practice in Germany. The ABC consensus is based on the votes of the ABC panelists in Lisbon.

IntroductionRegular blood glucose/A1c, blood pressure (BP), and cholesterol (ABC) testing is important for diabetes management. It is unknown whether pandemic-related disruptions in medical care were negatively associated with ABC testing among US adults with diagnosed diabetes.Research design and methodsA cross-sectional analysis was conducted among adults ≥18 years with diagnosed diabetes who participated in the 2019 or 2021 National Health Interview Survey (n=3355 and n=3127, respectively). Adults with diabetes self-reported sociodemographic and diabetes-related characteristics, ABC testing in the past year, and delays or not getting medical care due to the pandemic (2021 only). Descriptive statistics were used to determine differences in ABC testing in 2019 vs 2021. Logistic regression models were used to assess the association between delays or not getting medical care due to the pandemic and ABC testing, adjusting for sociodemographic characteristics, diabetes duration, and diabetes medication use.ResultsOverall, the prevalence of having a blood glucose/A1c or a BP test in the past year was high (>90%) but it was significantly lower in 2021 compared with 2019 (A1c: 94.2% vs 96.8%, p<0.001; BP: 96.8% vs 98.4%, p=0.002, respectively). Cholesterol testing remained stable (93.0% in 2021 vs 94.5% in 2019, p=0.053). In logistic regression analysis, after full adjustment, adults who reported delaying or not getting medical care when needed due to the pandemic were 50% less likely to get an ABC test in the past year compared with those who promptly received medical care (A1c: adjusted OR (aOR)=0.44, 95% CI 0.29–0.68; BP: aOR=0.48, 95% CI 0.27–0.85; cholesterol: aOR=0.48, 95% CI 0.31–0.75).ConclusionsDisruptions in medical care during the pandemic were associated with a decrease in ABC testing. Future research is needed to assess whether blood glucose/A1c and BP testing returns to prepandemic levels and if reductions in these tests result in excess diabetes-related complications.

Activity-based costing (ABC) success factors have been studied in past research, mostly by using commonly known success factors. In this qualitative study, a literature review and interviews were used to establish what factors are responsible for the successful implementation of ABC. The number of semi-structured interviews was limited to 13 ABC adopters in the Nelson Mandela Bay Metropole. The findings suggested that ABC can be enhanced with the use of activity-based budgeting (ABB) and activity-based management (ABM). In addition, the use of ABC in conjunction with capital investment decisions may ensure that correct decisions are made when critical long-term projects are considered. Extensive identification of cost drivers is beneficial to the extent where the product loses its relationship with the overhead cost. It is evident from this research that considering fixed indirect overheads in ABC is not always beneficial for a manufacturing organisation unless there is a clear link to the end-product.

ABC (glucose, blood pressure and LDL-cholesterol) goals are basic standards of diabetes care. We aimed to assess ABC control and related factors in a representative sample of Brazilian adults with diabetes. We analyzed 465 adults with known diabetes in the Brazilian National Health Survey. The targets used were <7% for glycated hemoglobin (A1C); <140/90 mmHg for blood pressure; and <100 mg/dL for LDL-C, with stricter targets for the latter two for those with high cardiovascular (CVD) risk. Individual goals were attained by 46% (95% CI, 40.3–51.6%) for A1C, 51.4% (95% CI, 45.7–57.1%) for blood pressure, and 40% (95% CI, 34.5–45.6%) for LDL-C. The achievement of all three goals was attained by 12.5% (95% CI, 8.9–16.2%). Those with high CVD risk attained blood pressure and LDL-C goals less frequently. A1C control improved with increasing age and worsened with greater duration of diabetes. Achievement of at least two ABC goals decreased with increasing BMI and greater duration of diabetes. In sum, about half of those with known diabetes achieved each ABC goal and only a small fraction achieved all three goals. Better access and adherence to treatment and strategies to personalize goals according to specific priorities are of the essence.

ABSTRACT Aureobasidin A (AbA) has strong antifungal effects arising from an unusual mechanism. We show that AbA interacts with ATP-binding cassette (ABC) transporters in yeast and mammalian cells. We isolated a gene ofSaccharomyces cerevisiae that conferred resistance to AbA when the gene was present in multiple copies. The gene was identical toYOR1/YRS1, which confers resistance to oligomycin, reveromycin, and organic anions, none of which have structures similar to that of AbA. We also isolated an aur3 Rrecessive mutant of S. cerevisiae with increased resistance to AbA. Northern hybridization showed that theaur3 R mutant expressed not onlyYOR1 but also the ABC transporter-encoding genePDR5 at high levels. Genetic studies showed that theaur3 R mutant had a mutation in thePDR1 gene, which encodes a transcriptional regulator ofPDR5 and YOR1. Analysis of a yor1disruptant of the aur3/pdr1 mutant showed that both the functional YOR1 gene and the mutation in PDR1were necessary for AbA resistance. These results suggest thatYOR1 is more important than PDR5 for AbA resistance. We found in Candida albicans a novel gene whose sequence was similar to the sequence of YOR1 in S. cerevisiae. The amino acid sequence of the C. albicans YOR1 homolog showed no significant similarity to the sequences ofCDR1 and CDR2, which are ABC transporters ofC. albicans. Furthermore, AbA inhibited the efflux of the anticancer agent vincristine through P glycoproteins in cancer cells with multidrug resistance.

ABSTRACTThere is pressing need in computation of a universal phase change memory consolidating the speed of RAM with the permanency of hard disk storage. A potentiated scanning tunneling microscope tip traversing the soliton separating a metallic, ABA-stacked phase and a semiconducting ABC-stacked phase in trilayer graphene has been shown to permanently transform ABA-stacked regions to ABC-stacked regions. In this study, we used density functional theory (DFT) calculations to assess the energetics of this phase-change and explore the possibility of organic functionalization using s-triazine to facilitate a reverse phase-change from rhombohedral back to Bernal in graphene trilayers. A significant deviation in the energy per simulated atom arises when s-triazine is adsorbed, favoring the transformation of the ABC phase to the ABA phase once more. A phase change memory device utilizing rapid, energy-efficient, reversible, field-induced phase-change in graphene trilayers could potentially revolutionize digital memory industry.

The implication-realization model hypothesizes that emotional syntax in music is a product of two expectation systems—one top down, the other bottom up. Syntactic mismatch or conflict in realizations can occur either within each system or between them. The theory argues that interruption or suppression of parametric expectations generated separately by the two systems explains certain types of recurrent aesthetic strategies in melodic composition and accounts for the most common kinds of musical forms (AAA, AAB, ABB, ABC, and ABA).

Finding a set of co-clusters in a bipartite network is a fundamental and important problem. In this paper, we present the Attributed Bipartite Co-clustering (ABC) problem which unifies two main concepts: (i) bipartite modularity optimization, and (ii) attribute cohesiveness. To the best of our knowledge, this is the first work to find co-clusters while considering the attribute cohesiveness. We prove that ABC is NP-hard and is not in APX, unless P=NP. We propose three algorithms: (1) a top-down algorithm; (2) a bottom-up algorithm; (3) a group matching algorithm. Extensive experimental results on real-world attributed bipartite networks demonstrate the efficiency and effectiveness of our algorithms.

ZusammenfassungVom 14. bis 16. November 2019 fand in Lissabon die fünfte internationale Konsensuskonferenz ABC5 (Advanced Breast Cancer Fifth Consensus) zu Diagnostik und Behandlung des fortgeschrittenen Mammakarzinoms statt. Ziel ist es, die Behandlung der Patientinnen mit fortgeschrittenem Mammakarzinom weltweit auf evidenzbasierter Grundlage zu standardisieren und sicherzustellen, dass Patientinnen überall auf der Welt adäquat behandelt werden und Zugang zu neuen Therapien erhalten. Ein inhaltlicher Schwerpunkt lag dieses Jahr auf neuen Entwicklungen und Studienergebnissen beim fortgeschrittenen Mammakarzinom sowie der Präzisionsmedizin. Zudem ist die Zusammenarbeit mit den Patientenvertreterinnen aus aller Welt ein wichtiges Anliegen der ABC-Konferenz, weshalb in dem international zusammengesetzten ABC-Panel auch Patientenvertreterinnen sind. Im vorliegenden Manuskript werden die Abstimmungsergebnisse der ABC5-Panelisten vor Ort durch eine Arbeitsgruppe deutscher Brustkrebsexperten für den Therapiealltag in Deutschland kommentiert. Der Kommentierung liegen die Empfehlungen der Arbeitsgemeinschaft Gynäkologische Onkologie (AGO), Kommission „Mamma“, zugrunde. Sie erscheint sinnvoll, da in den ABC-Konsensus auch länderspezifische Besonderheiten einfließen.

AbstractTopological indices are the atomic descriptors that portray the structures of chemical compounds and they help us to anticipate certain physico-compound properties like boiling point, enthalpy of vaporization and steadiness. The atom bond connectivity (ABC) index and geometric arithmetic (GA) index are topological indices which are defined as $ABC(G)=\sum_{uv\in E(G)}\sqrt{\frac{d_u+d_v-2}{d_ud_v}}$ and $GA(G)=\sum_{uv\in E(G)}\frac{2\sqrt{d_ud_v}}{d_u+d_v}$ , respectively, where du is the degree of the vertex u. The aim of this paper is to introduced the new versions of ABC index and GA index namely multiple atom bond connectivity (ABC) index and multiple geometric arithmetic (GA) index. As an application, we have computed these newly defined indices for the octagonal grid $O_p^q$ , the hexagonal grid H(p, q) and the square grid Gp, q. Also, we compared these results obtained with the ones by other indices like the ABC4 index and the GA5 index.

Concurrent attainment of glycated haemoglobin A1C, blood pressure, and LDL-cholesterol goals, or collectively known as the ‘ABC’ goals, help prevent cardiovascular complications in patients with type 2 diabetes (T2D). We aimed to determine the proportion of T2D patients who achieved all three ABC goals in Malaysia’s public health clinics. We also determined the association between age groups with the attainment of all the ABC goals. A cross-sectional analysis of the baseline findings from a retrospective open cohort study between 2013 and 2017 in Negeri Sembilan, Malaysia was conducted. The data was extracted from the National Diabetes Registry. The primary outcome was the proportion of patients who attained all three ABC goals. The exposure of interest was patients’ age groups, namely 18-44, 45-59 and ≥ 60 years. Multivariate logistic regression analysis was used to adjust demographics factors, comorbidities, complications and treatment profiles. Among 17,592 patients, the mean age was 59.1 years, with 56.3% females and 64.9% Malays. Overall, 4.5% (95% CI: 4.2-4.8) of the patients attained all the ABC goals. Compared to older adults aged ≥ 60 years, patients aged 18-44 and 45-59 years had adjusted odds ratios of 0.50 and 0.72, respectively, to achieve all the ABC goals. Ethnicity, body mass index, diabetes treatment modality, lipid-lowering agent and polypharmacy were independent factors associated with the outcome. In summary, achieving all the ABC goals in T2D patients is challenging, especially among younger adults. Our findings suggest that more targeted interventions should be directed towards this high-risk subpopulation.

The 5th International Consensus Conference for Advanced Breast Cancer (ABC5) took place on November 14–16, 2019, in Lisbon, Portugal. Its aim is to standardize the treatment of advanced breast cancer based on the available evidence and to ensure that all breast cancer patients worldwide receive adequate treatment and access to new therapies. This year, the conference focused on developments and study results in the treatment of patients with hormone receptor-positive/HER2-negative breast cancer as well as precision medicine. As in previous years, patient advocates from around the world were integrated into the ABC conference and had seats on the ABC consensus panel. In the present paper, a working group of German breast cancer experts comments on the results of the on-site ABC5 consensus votes by ABC panelists regarding their applicability for routine treatment in Germany. These comments take the recommendations of the Breast Committee of the Gynecological Oncology Working Group (Arbeitsgemeinschaft Gynäkologische Onkologie; AGO) into account. The report and assessment presented here pertain to the preliminary results of the ABC5 consensus. The final version of the statements will be published in Annals of Oncology and The Breast.

AbstractThe Advanced Breast Cancer Fifth International Consensus Conference (ABC5) which focuses on the diagnosis and treatment of advanced breast cancer was held in Lisbon on November 14 – 16, 2019. The aim of the conference is to standardize the treatment of advanced breast cancer worldwide using evidence-based data and to ensure that patients with advanced breast disease anywhere in the world are treated appropriately and have access to the latest therapies. This year, the emphasis was on new developments and study results from patients with advanced breast cancer as well as precision medicine. The collaboration with patient advocates from all over the globe is also an important goal of the ABC Conference, which is why the international ABC panel also included a number of patient advocates. We present a commentary on the voting results of the ABC5 panelists in Lisbon by a working group of German breast cancer specialists together with the implications for routine clinical care in Germany. The commentary is based on the recommendations of the Breast Commission of the German Gynecological Oncology Working Group (AGO). This commentary is useful, it includes country-specific features for the ABC consensus.

If we talk about the centre of a triangle, what might we be referring to? Any triangle has many different points that could regarded as its centre; in fact, Encyclopedia of Triangle Centres lists over 70 000 possibilities. Three of the most famous centres, that every triangle will possess (although they may coincide), are the incentre (where the three angle bisectors meet), the centroid (where the three medians meet) and the orthocentre (where the three altitudes meet). Proofs that these centres are well-defined and exist for every triangle are simple and satisfying, good examples of reasoning (if we are teachers) for our students. Proving the three altitudes of a triangle share a point using the scalar product of vectors is a wonderful demonstration of the power of this idea.

Neoplasia is a type of abnormal and excessive growth of tissue. The growth of a neoplasia is uncoordinated with that of the normal surrounding tissue, and it persists growing abnormally, even if the original trigger is removed. This abnormal growth usually forms a mass. The main objective of the present research work was the synthesis, characterization and evaluation of in vivo antitumour activity of some novel 2, 5-disubstituted 1, 3, 4-oxadiazole derivatives. The in vivo antitumour activity of synthesized compounds was evaluated by HT 29 cell line induced malignant ascites on mouse model. The apoptosis of HT 29 cells was evaluated by using Gimsa and H33342 stain and the apoptosis ratios were analysed by FCM using AnnexinV-FITC/PI staining. The present experimental data displayed that the mortality was less in all groups except in tumour control group and all the synthesized compounds AB1-AB8 (100 mg/kg) significantly increased the PILS. While 5-FU increased the life span of 97.72%, and the PILS of synthesized compounds were found to be 45.45%, 59.09%, 68.18%, 56.81%, 38.63%, 84.09%, 77.27% and 90.90%. So the Synthesized compounds AB1-AB8 at the dose of 100 mg/kg significantly improved the overall survival of all treated animals and 5-FU was not significantly differed from each other in improving the overall survival of HT-29 cells. The apoptosis ratios of synthesized compounds were found as followed: AB1=26%; AB2=37.6%; AB3=43%; AB4=29%; AB5=24.1%; AB6=59.2%; AB7=48.2%; and AB8=63% respectively, while that of the Group-II (T. control) was 6.1%. When compared with standard drug 5-FU: 66.2%, it was indicated that compound AB8>AB6>AB7>AB3 were able to significantly induce HT-29 cells apoptosis.

Abstract ABC-stacked trilayer graphene has exhibited a variety of correlated phenomena owing to its relatively flat bands and gate-tunable bandgap. However, convenient methods are still lacking for identifying ABC graphene with nanometer-scale resolution. Here we demonstrate that the scanning near-field optical microscope (SNOM) working in ambient conditions can provide quick recognition of ABC trilayer graphene with no ambiguity and excellent resolution (~20 nm). The recognition is based on the difference in their near-field infrared (IR) responses between the ABA and ABC trilayers. We show that in most frequencies, the response of the ABC trilayer is weaker than the ABA trilayer. However, near the graphene phonon frequency (~1585 cm-1), ABC’s response increases dramatically when gated and exhibits a narrow and sharp Fano-shape resonant line, whereas the ABA trilayer is largely featherless. Consequently, the IR contrast between ABC and ABA becomes reversed and can even be striking (ABC/ABA~3) near the graphene phonon frequency. The observed near-field IR features can serve as a golden rule to quickly distinguish ABA and ABC trilayers with no ambiguity, which could largely advance the exploration of correlation physics in ABC-stacked trilayer graphene.

Abstract Trilayer graphene consists of three layers of graphene arranged in a particular stacking order. In the case of ABC-ABA-ABC stacking, the layers are arranged in an A-B-C sequence, followed by an A-B-A sequence, and again an A-B-C sequence. This stacking arrangement introduces specific electronic properties and band structures due to the different stacking configurations. We focus on elucidating the transport properties of a p-n-p junction formed with ABC-ABA-ABC stacking TLG. Employing the transfer matrix method and considering continuity conditions at the junction boundaries, we establish transmission and reflection probabilities, along with conductance. Notably, electron transport through the ABC-ABA-ABC junction exhibits Klein tunneling, resulting in substantial conductance even in the absence of a potential barrier $V_0$. This effect arises from the effective barrier induced by our specific stacking, facilitating the passage of a maximal number of electrons. However, the presence of $V_0$ diminishes Klein tunneling, leading to conductance minima. Furthermore, our findings highlight that interlayer bias $\delta$ induces a hybridization of the linear and parabolic bands of ABA-TLG within the junction, reducing resonances. In cases where $\delta\neq0$ and $V_0\neq0$, we observe a suppression of the gap, contrary to the results obtained in ABC tunneling studies where a gap exists.
