Comparative study of the effects of ethnicity on the formation of political parties in Nigeria (1951-1961) and Sierra Leone (1950-1967)
Creators: name: Blell, Joseph C
Publisher: name: University of British Columbia
Year: 2011

description: This study will examine political party systems, with particular emphasis on the impact of ethnicity on party formation in both Nigeria (1951-1961) and Sierra Leone (1950-1967). Particularly in terms of this study, the hypothesis will be advanced that in countries as ethnically divided as Nigeria and Sierra Leone, political parties formed from a nucleus of members from one or another subsystem, such as an ethnic group, which engage in competitive elections will create sectional and ethnic tensions. The major finding of the study, is that a country or countries with sharp ethnic-cleavages, will tend to produce a multi-party system unless there are intervening factors to mitigate against such party-formation.

description: Context:Lespedeza cuneata G. Don (Fabaceae), has been used as a traditional treatment of various diseases. There is a report L. cuneata effects on hormone replacement therapy for endocrine-related disease. However, studies related to benign prostatic hyperplasia (BPH) have not been investigated. Objective: The effects of L. cuneata aqueous extract (LCW) on testosterone-induced prostatic hyperplasia (TPH) were examined. Materials and methods: Male Wistar rats (10 weeks, 330–350 g) were randomly divided to 6 groups (n = 6): Control group; TPH group (3 mg/kg, s.c, daily); TPH + LCW (25, 50, 100 mg/kg); TPH + Finasteride 10 mg/kg for 6 weeks. At the end of treatment, histological change of prostate, serum dihydrotestosterone (DHT) level, mRNA expression of 5α-reductase, inflammatory factors, proliferating cell nuclear antigen (PCNA) and fibroblast growth factor-2 (FGF-2) in prostate were examined. Then, LCW was treated with BPH-1, a human BPH cell line, at 25, 50, 100 μg/mL for 24 h and examine mRNA level of androgen receptor (AR) and prostate-specific antigen (PSA). In addition, the content of vicenin-2 was analyzed. Results: LCW treatment of TPH inhibited serum DHT levels by 54.5, 51.2 and 54.1% and mRNA expression of 5α-reductase were inhibited 54.3, 61.3 and 73.6%, respectively. In addition, mRNA expression of inflammatory factors, PCNA and FGF-2 were decreased in the prostate of rats. Also, LCW attenuated mRNA level of AR and PSA in BPH-1 cell. The content of vicenin-2 in the LCW was analyzed to 0.89 mg/g. Discussion and conclusions: Based on the results, LCW is a potential pharmacological candidate for the treatment of prostatic hyperplasia.

description: Everyone knows the importance of FAIR data principles, data reuse opportunities and provenance traceability. In this talk, Mario Valle will explore the technical and human, non-technical, prerequisites that make these principles concrete. The Swiss National Supercomputing Centre (CSCS) is supporting Swiss scientists by providing and managing Persistent Identifiers (PIDs) to name scientific data. Besides this base service, the CSCS is also experimenting and collecting use cases to make this deceptive simple thing, the PID string, a tool that could help speed up science in Switzerland.
Ruderman-Kittel-Kasuya-Yosida spin density oscillations: impact of the finite radius of the exchange interaction

description: A non-interacting electron gas on a one-dimensional ring is considered at finite temperatures. The localized spin is embedded at some point on the ring and it is assumed that the interaction between this spin and the electrons is the exchange interaction being the basis of the Ruderman-Kittel-Kasuya-Yosida indirect exchange effect. When the number of electrons is large enough, it turns out that any small but finite interaction radius value can always produce an essential change of the spin density oscillations in comparison with the zero interaction radius traditionally used to model the Ruderman-Kittel-Kasuya-Yosida effect.

We show that blow-up in a finite time occurs for the equation with arbitrary power nonlinearity as well as upper bounds of the lifespan of blow-up solutions.The blow-up condition is the same as in the accelerated expanding Friedmann-Lemaître-Robertson-Walker (FLRW) spacetime. We also show the same results for the space derivative nonlinear term.

description: This document reports on the developments needed to produce management tools that are relevant for each of the case studies in the FarFish project. The tools have been selected in coordination with the production of Management Plan zero for each case study (D4.1 - MP0 for each case study). It has shared with Work Package 4 the consultation process with partners of FarFish, including the case study leaders, and with external relevant bodies such as ICCAT or IOTC. The selected tools have been incorporated into the Management Plan Zero and have also been coordinated with Work Package 2 to feed through Deliverables 2.3 (Report on biological and ecological data in FFDB pilot version 1) and 2.6 (Report on biological and ecological data in FFDB pilot version 2), and the data these tools will demand. The tools are planned to use the data available from the FarFish database (D6.2 – FFDB pilot version 1, D6.5 – FFDB pilot version 2, D6.9 - FFDB) and to provide results that will be stored in the same database. They incorporate measures to explore better compliance through satellite advances in sensing and communication, models for semi-automatic stock assessment when needed or assessment of the role of the physical environment in creating stock fluctuations. They have all been identified during the consultancy process as necessary and non-redundant with the tools presently available in the different case studies.

Publisher: name: arXiv
Year: 2010
Subjects: subject: Databases (cs.DB)

description: The problem of developing models and algorithms for multilevel association mining pose for new challenges for mathematics and computer science. These problems become more challenging, when some form of uncertainty like fuzziness is present in data or relationships in data. This paper proposes a multilevel fuzzy association rule mining models for extracting knowledge implicit in transactions database with different support at each level. The proposed algorithm adopts a top-down progressively deepening approach to derive large itemsets. This approach incorporates fuzzy boundaries instead of sharp boundary intervals. An example is also given to demonstrate that the proposed mining algorithm can derive the multiple-level association rules under different supports in a simple and effective manner.
Review of Data Integrity Attacks and Mitigation Methods in Edge computing

Year: 2021
Subjects: subject: Cryptography and Security (cs.CR)

description: In recent years, edge computing has emerged as a promising technology due to its unique feature of real-time computing and parallel processing. They provide computing and storage capacity closer to the data source and bypass the distant links to the cloud. The edge data analytics process the ubiquitous data on the edge layer to offer real-time interactions for the application. However, this process can be prone to security threats like gaining malicious access or manipulating sensitive data. This can lead to the intruder's control, alter, or add erroneous data affecting the integrity and data analysis efficiency. Due to the lack of transparency of stakeholders processing edge data, it is challenging to identify the vulnerabilities. Many reviews are available on data security issues on the edge layer; however, they do not address integrity issues exclusively. Therefore, this paper concentrates only on data integrity threats that directly influence edge data analysis. Further shortcomings in existing work are identified with few research directions.

description: The field of ground-based gamma ray astronomy has enjoyed rapid growth in recent years. As an increasing number of sources are detected at TeV energies, the field has matured and become a viable branch of modern astronomy. Lying at the uppermost end of the electromagnetic rainbow, TeV photons are always preciously few in number but carry essential information about the particle acceleration and radiative processes involved in extreme astronomical settings. Together with observations at longer wavelengths, TeV gamma-ray observations have drastically improved our view of the universe. In this review, we briefly describe recent progress in the field. We will conclude by providing a personal perspective on the future of the field, in particular, on the significant roles that China could play to advance this young but exciting field.

description: PIDs and their metadata support scholarly research and its increasing amounts and
variety of scholarly output. DataCite provides services which enable the research community to identify, connect, cite and track these outputs, making content FAIR. New
services include data level metrics and the use of identifiers for organizations and new
types of content, e.g. software, repositories and instruments. As an open, collaborative
and community driven membership organization we rely on our members for their
input and experience to build services that are beneficial for the research community
as a whole. DataCite services as well as current and future initiatives will be described
and it will be shown how members can contribute and benefit. Over the course of the
years, our membership has grown and diversified and we are therefore refreshing and
clarifying our member model. The new member model will be presented and described.

Tracking citations to research software via PIDs

description: Tracking citations to research software via persistent identifiers is difficult due to dilution of citations over many PIDs assigned to a software package. On top of this, software citations are often consistently being edited out by every actor part of the scholarly communication process such as reference managers, publishers, professors and discovery systems. Thus, the survival rate of a software citation is extremely low in the current scholarly ecosystem. The Sloan-funded Asclepias project is a collaboration between a publisher, discovery system and repository with the goal to promote scientific software into an identifiable, citable, and preservable object. We have built a citation broker that is currently tracking some 6.000 citations to Zenodo DOIs from NASA ADS,
CrossRef and EuropePMC.

description: Some features of the global entanglement of a composed quantum system can be quantified in terms of the purity of a balanced bipartition, made up of half of its subsystems. For the given bipartition, purity can always be minimized by taking a suitable (pure) state. When many bipartitions are considered, the requirement that purity be minimal for all bipartitions can engender conflicts and frustration arises. This unearths an interesting link between frustration and multipartite entanglement, defined as the average purity over all (balanced) bipartitions.

Trusted Timestamping via the Bitcoin Blockchain
Creators: name: Gipp, Bela
Publisher: name: ETH Zurich
Year: 2019

description: In his talk, Bela Gipp, Professor for Data & Knowledge Engineering at the University of Wuppertal, presented the blockchain-based trusted timestamping service Origin-Stamp. Bela developed OriginStamp as a Ph.D. student in 2012, as no convenient and tamper-proof method existed to create timestamps. Since then, OriginStamp has been used over 6 million times by researchers, journalists in war regions, pharmaceutical companies, and individuals. Use cases are the timestamping of ideas for patent applications, timestamping of digital archives or timestamping of pre-existing damage, e.g., when hiring a rental car. The service can be used via a website, mobile phone apps, or an API, which allows developers to easily make use of trusted timestamping in their own applications. Trusted timestamping is the process of securely tracing the creation and modification time of any digital file. In contrast to conventional commercial timestamping authorities, OriginStamp uses the blockchain of the cryptocurrency Bitcoin as a decentralized, tamper-proof, and cost-efficient timestamping authority.

description: Context:Kochia scoparia (L.) Schrad (Amaranthaceae), known as a traditional medicine in China, Japan and Korea, is reported to have various biological activities. However, K. scoparia seed extract (KSE) functional roles on angiogenesis and prostate cancer inhibition have not been elucidated. Objective: This study elucidates the effects of KSE on vascular endothelial growth factor (VEGF)-induced angiogenesis in human umbilical vein endothelial cells (HUVECs) and inhibition of proliferation in prostate cancer cells. Materials and methods: HUVECs were treated with 10–20 µg/mL of KSE and 20–50 ng/mL of VEGF for 12–72 h. Anti-angiogenesis properties of KSE were determined by wound healing, trans-well, tube formation, rat aortic ring assay and western blotting. Prostate cancer and normal cells were incubated with 10–250 µg/mL of KSE for 24 h, and cell viability was measured by SRB assay. Phenolic compounds in KSE were analyzed using a HPLC-PDA system. Results: IC50 for cell viability of HUVECs, LNCaP, PC-3, RC-58T and RWPE-1 by KSE were 30.64, 89.25, 123.41, 141.62 and >250 µg/mL, respectively. Treatment with KSE (20 µg/mL) significantly suppressed VEGF-induced migration, invasion and capillary-like structure formation of HUVECs and microvessel sprouting from rat aortic rings. In addition, KSE down-regulated PI3K/AKT/mTOR levels and phosphorylation of VEGF receptor 2 in HUVECs. 3-OH-tyrosol (1.63 mg/g) and morin hydrate (0.17 mg/g) were identified in KSE. Conclusions: KSE inhibits angiogenesis in HUVECs as well as proliferation in human prostate cancer cells, suggesting KSE may be useful herbal medicine for preventing progression of prostate cancer and angiogenesis.
Applying MVC and PAC patterns in mobile applications

Publisher: name: arXiv
Year: 2010
Subjects: subject: Software Engineering (cs.SE)
subject: FOS: Computer and information sciences

description: Additional requirements are set for mobile applications in relation to applications for desktop computers. These requirements primarily concern the support to different platforms on which such applications are performed, as well as the requirement for providing more modalities of input/output interaction. These requirements have influence on the user interface and therefore it is needed to consider the usability of MVC (Model-View-Controller) and PAC (Presentation-Abstraction-Control) design patterns for the separation of the user interface tasks from the business logic, specifically in mobile applications. One of the questions is making certain choices of design patterns for certain classes of mobile applications. When using these patterns the possibilities of user interface automatic transformation should be kept in mind. Although the MVC design pattern is widely used in mobile applications, it is not universal, especially in cases where there are requirements for heterogeneous multi-modal input-output interactions.
Exact boundary-value solution for an electromagnetic wave propagating in a linearly-varying index of refraction

Year: 2024

subject: FOS: Physical sciences

description: The propagation of electromagnetic waves in a linearly-varying index of refraction is a fundamental problem in wave physics, being relevant in fusion science for describing certain wave-based heating and diagnostic schemes. Here, an exact solution is obtained for a given incoming wavefield specified on the boundary transverse to the direction of inhomogeneity by performing a spectral, rather than asymptotic, matching. Two case studies are then presented: a Gaussian beam at oblique incidence and a speckled wavefield at normal incidence. For the Gaussian beam, it is shown that when the waist $W$ is sufficiently large, oblique incidence manifests simply as rigid translation and focal shift of the corresponding diffraction pattern at normal incidence. The destruction of the hyperbolic umbilic caustic (corresponding to a critically focused beam) as $W$ is reduced is then demonstrated. The caustic disappears once $W \lesssim δ_a \sqrt{L}$ ($L$ being the medium lengthscale normalized by the Airy skin depth $δ_a$), at which point the wave behavior is increasingly described by Airy functions, but experiences less focusing as a result. To maximize the intensity of a launched Gaussian beam at a turning point, one should therefore minimize the imaginary part of the launched complex beam parameter while having the real part satisfy critical focusing. For the speckled wavefield, it is shown that the transverse speckle pattern only couples to the Airy longitudinal pattern when the coupling parameter $η= \sqrt{L}/f_\#$ is large, with $f_\#$ being the f-number of the launching aperture. When $η\ll 1$, a reduced description of the total wavefield can be obtained by simply multiplying the incoming speckle pattern with the Airy swelling.

description: We constrain the space density and properties of massive galaxy candidates at redshifts of z>=3.5 in the GOODS-N field. By selecting sources in the Spitzer+IRAC bands, a highly stellar mass-complete sample is assembled,including massive galaxies which are very faint in the optical/near-IR bands that would be missed by samples selected at shorter wavelengths. The z>=3.5 sample was selected down to 23 mag at 4.5 micron using photometric redshifts that have been obtained by fitting the galaxies SEDs at optical, near-IR and IRAC bands. We also require that the brightest band in which candidates are detected is the IRAC 8 micron band in order to ensure that the near-IR 1.6 micron (rest-frame) peak is falling in or beyond this band. We found 53 z>=3.5 candidates, with masses in the range of M~10^10-10^11M_sun. At least ~81% of these galaxies are missed by traditional Lyman Break selection methods based on UV light. Spitzer+MIPS emission is detected for 60% of the sample of z>=3.5 galaxy candidates. Although in some cases this might suggest a residual contamination from lower redshift star-forming galaxies or AGN, 37% of these objects are also detected in the sub-mm/mm bands in recent SCUBA,AzTEC and MAMBO surveys, and have properties fully consistent with vigorous starburst galaxies at z>=3.5. The comoving number density of galaxies with stellar masses >= 5x10^10M_sun(a reasonable stellar mass completeness limit for our sample) is 2.6x10^-5Mpc^-3 (using the volume within 3.5

description: The discovery of an HI cloud with peculiar properties at equatorial coordinates (J2000) ra=07h49m, dec=04d30m is presented. The HI object was detected at 21cm using the 300-m NAIC Arecibo telescope. Subsequent follow-up high-resolution observations with the NRAO Very Large Array (VLA) telescope at L-Band revealed more details about its morphology. The most intriguing aspect of the object is the clear velocity gradient of 1 km/s, which is present in the data, an indication of either rotation or expansion. The gas appears to be cold, and its morphology is somewhat elliptical with clumpy substructure. Assuming disk rotation, the dynamical mass could be determined as a function of distance.Depending on the exact nature of the velocity gradient in the HI cloud, we can reach some preliminary conclusions about the nature of the object. Expansion would imply association with a circumstellar envelope of an evolved AGB star, while in the case of rotation, a comparison between the visible and the dynamical mass can lead to some preliminary conclusions. A common feature of those conclusions is the presence of a gravitational potential well, which is required to account for the rotation of the trapped HI gas. This potential well could be associated with a dark galaxy or some other exotic object.

MetaCloth: Learning Unseen Tasks of Dense Fashion Landmark Detection from a Few Samples

description: Recent advanced methods for fashion landmark detection are mainly driven by training convolutional neural networks on large-scale fashion datasets, which has a large number of annotated landmarks. However, such large-scale annotations are difficult and expensive to obtain in real-world applications, thus models that can generalize well from a small amount of labelled data are desired. We investigate this problem of few-shot fashion landmark detection, where only a few labelled samples are available for an unseen task. This work proposes a novel framework named MetaCloth via meta-learning, which is able to learn unseen tasks of dense fashion landmark detection with only a few annotated samples. Unlike previous meta-learning work that focus on solving "N-way K-shot" tasks, where each task predicts N number of classes by training with K annotated samples for each class (N is fixed for all seen and unseen tasks), a task in MetaCloth detects N different landmarks for different clothing categories using K samples, where N varies across tasks, because different clothing categories usually have various number of landmarks. Therefore, numbers of parameters are various for different seen and unseen tasks in MetaCloth. MetaCloth is carefully designed to dynamically generate different numbers of parameters for different tasks, and learn a generalizable feature extraction network from a few annotated samples with a set of good initialization parameters. Extensive experiments show that MetaCloth outperforms its counterparts by a large margin.

description: Context:Eclipta prostrata L. (Asteraceae) (EP) has been widely used for the treatment of skin disease in Asian traditional medicine. Objective: This study investigates the potency of EP in promoting hair growth in vivo and in vitro. Materials and methods: C57BL/6N mice were divided into four groups (n = 4) as follows: control (topical treatment of normal saline), topical 3% minoxidil to the dorsal skin of mice for 14 days, and low (1 mg/day) and high (10 mg/day) doses of EP orally administered once a day for 14 days. Dorsal hairs of C57BL/6N mice were depilated to synchronize anagen induction. Hair growth activity was evaluated by gross and microscopic observations. Sections of dorsal skin were stained with haematoxylin and eosin. We also treated the various concentrations of EP (5, 10 and 50 μg/mL) for 24 h on the human dermal papilla cells (HDPs) and examined the effects of EP on the expression of FGF-7 and mTOR signalling. Results: EP enhanced the induction of anagen in the dorsal skin of mice, characterized by the appearance of inner root sheath along with hair shaft, the emergence of hair shaft through the epidermis. EP increased the expression of FGF-7, while decreased the level of FGF-5 in C57/BL6 mice. EP also increased the expression of FGF-7, activated the mTOR signalling in HDPs. Discussion and conclusions: These results suggest that EP has a potency to enhance the growth of hair follicle, promoting hair growth through regulation of FGF-7 and FGF-5.
What you cite is what you get? Verifiable addressing of immutable, self-describing research data
Creators: name: Ó Carragáin, Eoghan
Publisher: name: ETH Zurich
Year: 2019

description: The requirements of FAIR and Reproducible Science are driving new PID requirements around the citation of exact, verifiable versions of research outputs. For example, versioned DOIs have been implemented on various popular platforms (Figshare, Zenodo, F1000). There is also renewed interest in the idea of data packaging as a practical means of bundling data and metadata in a way that can be easily cited and transmitted as a single payload. Similarly, several groups have identified the need to directly and unambiguously reference the exact content of a data payload in PID metadata:
— for example, the Freya project is looking at how best to allow “direct access to content associated with a DOI” (see https://github.com/datacite/freya/issues/2),
— RDA is tackling similar issues in the PID Kernel Information Working Group (https://www.rd-alliance.org/groups/pid-kernel-information-wg),
— and the Software Heritage made ‘verifiability’ a key property of their PID design (https://hal.archives-ouvertes.fr/hal-01865790).
This all suggests an appetite within the research community for greater consensus around linking PIDs to versioned (and therefore immutable), self-describing content. Beyond the scholarly communication ecosystem, a number of projects, notably the Interplanetary FileSystem (IPFS) and DAT, use content-addressed, peer-to-peer networks to bake these properties right into the fabric of the network, in a way that has potentially interesting implications for how we share reproducible research outputs. This talk will provide an overview of these issues, explore some of the emerging solutions in the area, as well as the challenges inherent in new approaches.

description: We report a detailed study of a model Hamiltonian which exhibits a rich interplay of geometrical spin frustration, strong electronic correlations, and charge ordering. The character of the insulating phase depends on the magnitude of Delta/|t| and on the sign of t. We find a Mott insulator for Delta >> U >> |t|; a charge transfer insulator for U >> Δ>> |t|; and a correlated covalent insulator for U >> Δ~ |t|. The charge transfer insulating state is investigated using a strong coupling expansion. The frustration of the triangular lattice can lead to antiferromagnetism or ferromagnetism depending on the sign of the hopping matrix element, t. We identify the "ring" exchange process around a triangular plaquette which determines the sign of the magnetic interactions. Exact diagonalization calculations are performed on the model for a wide range of parameters and compared to the strong coupling expansion. The regime U >> Δ~ |t| and t<0 is relevant to Na05CoO2. The calculated optical conductivity and the spectral density are discussed in the light of recent experiments on Na05CoO2.

description: Context:Lespedeza cuneata G. Don (Fabaceae), has been used as a traditional treatment of various diseases. There is a report L. cuneata effects on hormone replacement therapy for endocrine-related disease. However, studies related to benign prostatic hyperplasia (BPH) have not been investigated. Objective: The effects of L. cuneata aqueous extract (LCW) on testosterone-induced prostatic hyperplasia (TPH) were examined. Materials and methods: Male Wistar rats (10 weeks, 330–350 g) were randomly divided to 6 groups (n = 6): Control group; TPH group (3 mg/kg, s.c, daily); TPH + LCW (25, 50, 100 mg/kg); TPH + Finasteride 10 mg/kg for 6 weeks. At the end of treatment, histological change of prostate, serum dihydrotestosterone (DHT) level, mRNA expression of 5α-reductase, inflammatory factors, proliferating cell nuclear antigen (PCNA) and fibroblast growth factor-2 (FGF-2) in prostate were examined. Then, LCW was treated with BPH-1, a human BPH cell line, at 25, 50, 100 μg/mL for 24 h and examine mRNA level of androgen receptor (AR) and prostate-specific antigen (PSA). In addition, the content of vicenin-2 was analyzed. Results: LCW treatment of TPH inhibited serum DHT levels by 54.5, 51.2 and 54.1% and mRNA expression of 5α-reductase were inhibited 54.3, 61.3 and 73.6%, respectively. In addition, mRNA expression of inflammatory factors, PCNA and FGF-2 were decreased in the prostate of rats. Also, LCW attenuated mRNA level of AR and PSA in BPH-1 cell. The content of vicenin-2 in the LCW was analyzed to 0.89 mg/g. Discussion and conclusions: Based on the results, LCW is a potential pharmacological candidate for the treatment of prostatic hyperplasia.
Creative writer in politics : George Orwell's Burmese days : a study of imperialism at the local level
Creators: name: Slater, Ian David
Publisher: name: University of British Columbia
Year: 2011

description: This study examines George Orwell's contribution to our understanding of imperialism and to political writing in general. The basic assumptions of the study are that for a creative writer plot performs essentially the same function as model-building does for the political scientist and the role of the imagination is paramount both in the drawing of a novelist's picture of environment and in a social scientist's selection of variables. To show how a creative writer can offer the student of politics an unusual perspective of various systems of government (in this case, imperialism), the study draws upon concrete examples from Orwell's novel Burmese Days and other of his related writings to illustrate a number of political science's theoretical concepts. The study is also concerned with showing how Orwell was a pacesetter, as it were, in rejecting jargon as a means of expression and instead pressing vigorously, particularly in his description of imperialism in Burmese Days, for a straightforward yet imaginative prose in describing political as well as other events. The study assumes that Orwell's plea is echoed in a succeeding generation by others such as Landau and asserts that Burmese Days has either rendered many of imperialism's more harmful clichés impotent or has at least exposed them to closer scrutiny. At the same time, despite Orwell's often vehement denunciation of imperialism, it is assumed that there is implicit in the dialogue of some of his characters a recognition that while the system of uninvited foreigners exploiting and governing another people's country may be morally repugnant, in the light of an all-embracing and privacy-invading industrialism British imperialism may have been the least offensive kind of such exploitation. The study argues that our understanding of the motivations for group behaviour may, in some cases such as imperialism, be best pursued through more intensive studies of individuals within the group rather than by investing all of our attention in observing the collective action of the group. The study has evolved not from the notion that a creative writer can ever replace the perhaps more disciplined approach of the social sciences in understanding our world, but that he can significantly aid the academic world in illustrating its theoretical concepts. Finally, it is the overriding conclusion of this study that the moderately experimental nature of its juxtaposition of social science theory and fiction is mutually beneficial to both the social scientist and the student of literature in offering them new perspectives in their respective fields of interest.

description: Context:Cola gigantea A. Chev. (Sterculiaceae) is an important medicinal tropical flora. Objective: The seed oil of C. gigantea, an underutilized tropical plant was investigated for its antioxidant, anti-inflammatory, anti-Toxoplasma, and cytotoxicity activities as well as the chemical composition. Materials and methods: The physicochemical parameters of the seed oil obtained via Soxhlet extraction was determined while the fatty acid and non-fatty acid component were analyzed by gas chromatography-mass spectrometry. The antioxidant activity was evaluated using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2-azino-bis-(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) assays (10–50 µg/mL) while the anti-inflammatory property was determined through Cell Membrane Stabilization assay. The anti-parasite and cytotoxicity activity were evaluated (0–1000 µg/mL) using Toxoplasma gondii and mammalian cell line assays, respectively. Results: The oil had fatty acids which ranged from C-12 to C-23 with linoleic (18:2) and palmitic acids (16:0) being dominant. The oil had 89.41% unsaturated fatty acids with sterolic acid, an uncommon acetylenic fatty acid reported for the first time. Non-fatty acids obtained include cholesterol (2.12%), campesterol (14.12%), stigmasterol (34.07%) and β-sitosterol (49.68%). The oil had a significantly (p 50 > 50 µg/mL) compared with ascorbic acid. In contrast, the oil showed better activity against ABTS radicals (IC50 44.19 ± 6.27 µg/mL) compared with ascorbic acid or quercetin. Furthermore, the oil showed anti-T. gondii and dose-dependent cytotoxicity in HFF cells with selectivity index (IC50/EC50 Discussion and conclusions: The antioxidant potential of the oil suggests that it may serve as a potential source for various preparations for pharmaceuticals and cosmeceuticals.

description: We study how the explicit symmetry breaking, through a continuous parameter in the Lagrangian, can actually lead to the creation of different types of symmetries. As examples we consider the motion of a relativistic particle in a curved background, where a nonzero mass breaks the symmetry of the conformal algebra of the metric, and the motion in a Bogoslovsky-Finsler space-time, where a Lorentz violation takes place. In the first case, new nonlocal conserved charges emerge in the place of those which were previously generated by the conformal Killing vectors, while in the second, rational in the momenta integrals of motion appear to substitute the linear expressions corresponding to those boosts which fail to be symmetries.

description: Context:Eclipta prostrata L. (Asteraceae) (EP) has been widely used for the treatment of skin disease in Asian traditional medicine. Objective: This study investigates the potency of EP in promoting hair growth in vivo and in vitro. Materials and methods: C57BL/6N mice were divided into four groups (n = 4) as follows: control (topical treatment of normal saline), topical 3% minoxidil to the dorsal skin of mice for 14 days, and low (1 mg/day) and high (10 mg/day) doses of EP orally administered once a day for 14 days. Dorsal hairs of C57BL/6N mice were depilated to synchronize anagen induction. Hair growth activity was evaluated by gross and microscopic observations. Sections of dorsal skin were stained with haematoxylin and eosin. We also treated the various concentrations of EP (5, 10 and 50 μg/mL) for 24 h on the human dermal papilla cells (HDPs) and examined the effects of EP on the expression of FGF-7 and mTOR signalling. Results: EP enhanced the induction of anagen in the dorsal skin of mice, characterized by the appearance of inner root sheath along with hair shaft, the emergence of hair shaft through the epidermis. EP increased the expression of FGF-7, while decreased the level of FGF-5 in C57/BL6 mice. EP also increased the expression of FGF-7, activated the mTOR signalling in HDPs. Discussion and conclusions: These results suggest that EP has a potency to enhance the growth of hair follicle, promoting hair growth through regulation of FGF-7 and FGF-5.
Thermal radiation from Lorentzian traversable wormholes

description: In this paper we show that, analogously to as it occurs for black holes, there exist three well-defined laws for Lorentzian wormhole thermodynamics and that these laws are related with a thermal phantom-like radiation process coming from the wormhole throat. It is argued that the existence of wormholes could be manifested by means such a radiation. These results are obtained by analyzing the Hayward formalism of spherically symmetric solutions containing trapping horizons, the phenomenon of phantom accretion onto wormholes and the development of phantom thermodynamics.

Year: 2023

description: This project aimed to model the three-dimensional field around a lightning rod prior to a lightning strike. The project is largely theoretical and discusses the various processes that have to be included to accurately model the voltage distribution and the charge density around the tip of the rod. A program has been written in C++ to model the potential distribution around a lightning rod in three-dimensions. This program provides a framework for the solution of the three-dimensional problem.
