Exploring Literature: The Language and Logic of Liberation (Kawaida and Mato Oput) (2008)

In my usual call for papers and participation, a few step forward with productive content. This issue is thus the result of part of that effort as JPAS editorial member Dr. Uhuru Hotep organized a call to engage in a discussion of the Kawaida derived concern via Dr. Maulana Karenga for a logic and language of liberation (Karenga, Maulana. Kawaida and Questions of Life and Struggle: African American, Pan African and Global Issues. Los Angeles: University of Sankore Press, 2008; Kawaida Theory: An Introductory Outline. Inglewood, CA: Kawaida Publications, 1980). Consequently, I thank Dr. Hotep for his initiative, and overall activist thrust to advance the content of JPAS. This edition therefore echo and parallel our quest for a logic and language of liberation. Dr. Hotep has organized content using the metaphor of the journey toward enlightenment to identify six levels of knowing called the Johari Sita that lie at the core of the intellectual maroon worldview; Jared A. Ball argues that the agency represented within a logic and language of Black liberation has been aggressively suppressed, thus, those interested moving it forward must be willing to engage themselves in a mass media environment so they can enter the levels of production and dissemination to establish a transformative discourse; Albino Deng Ajuok of South Sudan provides a historical overview of the unity of African nationalism and Pan Africanism linking the African people of the Sudan to the political socio-cultural and philosophical articulation of African world nationhood; Antonette Jefferson, a Ph.D. student at Howard University via generic rhetorical criticism examines the rhetoric of revolution through the Black Consciousness Movement and the Dalit Panther Movement; Nelson O. Fashina works to carve a distinct critical canon for the reading of African/Black literature to show that African names for humans, flora and fauna, and other units used in African literary and cultural discourses are ritualistic and historical, and thus carry sacred meanings; Iyabode Omolara Daniel critically investigates how contemporary Nigerian poets employ nature as a metaphor to signify the dissonant relationship between the people of the Niger-Delta and the Nigerian government via the poems of Ebi Yeibo and Molara Ogundipe-Leslie; Ginette Ba-Curry looks at the plight of the Senegalese woman in pre-colonial, colonial and post-colonial Senegal through the comparative analysis of Cheikh Hamidou Kane's The Most Royal Lady in Ambiguous Adventure and Mariama Ba's female characters in So Long a Letter; Anthony B. …
Temperature dependence of reactive ion etching of GaAs with CCl2F2:O2 (1989)

The etch rate of GaAs during reactive ion etching (RIE) in a CCl2F2:O2 discharge (4 mTorr, 0.56 W cm−2) shows a strong temperature dependence, increasing from ∼500 Å min−1 at 50 °C to 2800 Å min−1 at 400 °C. Arrhenius plots of the etch rate show two activation energies (0.17 eV from 50 to 150 °C and 0.11 eV from 150 to 400 °C). There is no significant plasma power density dependence of the etch rate at elevated temperatures (≥100 °C) in contrast to the strong dependence at 50 °C. The surface morphology undergoes smooth-to-rough-to-smooth-to-rough transitions at ∼150, 250, and 400 °C, respectively, although TiPtAu Schottky diodes exhibit near-ideal behavior on GaAs etched at 150 °C. The As-to-Ga ratio in the first 100 Å from the surface increases with increasing RIE temperature, with chloride residues absent above 150 °C. Fluorocarbon residues were present on all samples, but were limited to the first 10–15 Å. As determined by x-ray photoelectron spectroscopy, fluorine was present almost exclusively as metallic gallium fluorides, while oxygen was present as both Ga and As oxides. Ion channeling detected lattice disorder to depths of ∼200 Å for etch temperatures from 50 to 250 °C, while there was less damage for etching at 400 °C. No new RIE-induced deep levels were observed by capacitance transient spectroscopy in any of our samples, although the concentration of the midgap donor EL2 increased with increasing temperature during the RIE process.
New noncompetitive immunoassays of small analytes (1995)

We developed a novel noncompetitive immunoassay format for monoepitopic analytes and describe here a model assay for triiodothyronine (T3), performed on Ciba Corning's ACS:180 analyzer. Acridinium ester (AE)-labeled bivalent anti-T3 was incubated with the sample, producing AE-anti-T3/T3 complexes and unreacted AE-anti-T3. Controlled-pore glass particles (CPG) with immobilized diiodothyronine (T2) were then added in excess, to bind AE-anti-T3 possessing two unoccupied binding sites but not AE-anti-T3 bound to one or two T3 molecules. Paramagnetic particles (PMP) with immobilized anti-AE were then added to the same cuvette to capture AE-anti-T3/T3 complexes; AE-anti-T3 bound to the surface of CPG, however, was not captured, because of steric hindrance. After the incubation, the PMP was magnetically separated to remove the liquid phase and the suspended CPG from the cuvette. The chemiluminescence associate with the PMP remaining in the cuvette was then measured. This noncompetitive T3 assay exhibited a 10-fold lower detection limit than the equivalent competitive T3 assay, i.e., 0.3 vs pg/test. Imprecision (CV) in the clinically significant range was 6% or less. The assay also displayed two- to sevenfold lower cross-reactivities and a wider dynamic range.
Snowsat - a Ku--band SAR mission for climate research and hydrology (2004)

Based on requirements for improved observations of snow and ice in climate research and hydrology, SNOWSAT, a satellite mission for observation of the cryosphere from regional to global scales, was elaborated. As payload a co- and cross- polarized Ku-band (17 GHz) SAR was selected, because of its sensitivity to dry snow, thin sea ice, and the metamorphic state of snow, firn and ice on glaciers and ice caps. A ScanSAR scheme with a linear array of 3 parabolic reflectors, each with multiple beams, was chosen to fulfil the requirements for swath width and spatial resolution and to avoid antenna deployment. SNOWSAT, operating in two different modes for climate applications and hydrology, represents an innovative, cost-effective solution for monitoring a wide range of snow and ice parameters.
A Replicable Comparison Study of NER Software: StanfordNLP, NLTK, OpenNLP, SpaCy, Gate (2019)

Named Entity Recognition (NER) is a key building block of any Natural Language Processing (NLP) system, making possible the detection and classification of entities (e.g., Person, Location) in any given text. While a large number of NER software exist today, it remains difficult for NLP and NER practitioners to clearly and objectively identify what software perform(s) the best. One of the reasons is the difference in results across the literature and the lack of information needed to be able to fully reproduce the experiment. To overcome this problem, this paper presents a comprehensive and replicable study to assess the performance of NER software, thus laying the groundwork for future benchmarking and meaningful comparison studies. As part of our experiments, the latest version of five well-known NER software were selected, along with two distinct corpora. We observe a discrepancy between the result we get and the result found in the literature being around 50% in certain cases. We also found that StanfordNLP usually performs the best.
Jetting of Structural Casing in Deepwater Environments: Job Design and Operational Practices (2006)

Abstract Structural casing jetting operations have become commonplace in deepwater environments. Having originated in the Gulf of Mexico, structural casing is now jetted in most deepwater basins in the world. Very little literature has been published regarding jetting practices. Indeed, jetting operations remain as much an art as a science to a large degree. This paper reviews current deepwater structural casing jetting job design and operational practices. Also included are several case histories of jetting failures presented in order to share learnings with the industry and to stimulate the sharing of learnings and practices.
CD4 T cells: fates, functions, and faults (2008)

In 1986, Mosmann and Coffman identified 2 subsets of activated CD4 T cells, Th1 and Th2 cells, which differed from each other in their pattern of cytokine production and their functions. Our understanding of the importance of the distinct differentiated forms of CD4 T cells and of the mechanisms through which they achieve their differentiated state has greatly expanded over the past 2 decades. Today at least 4 distinct CD4 T-cell subsets have been shown to exist, Th1, Th2, Th17, and iTreg cells. Here we summarize much of what is known about the 4 subsets, including the history of their discovery, their unique cytokine products and related functions, their distinctive expression of cell surface receptors and their characteristic transcription factors, the regulation of their fate determination, and the consequences of their abnormal activation.

Dual slot-coupled microstrip antenna for dual frequency operation (1993)

A new dual slot-coupled circular microstrip antenna for dual frequency or dual polarisation operation is proposed. By optimising the placement of the two slots, high isolation between two ports is achieved. Experimentally, an isolation of more than 35dB is obtained at L-band.
A MULTI-FUNCTIONAL CANTILEVER FOR ENERGY SCAVENGING FROM VIBRATIONS (2008)

To overcome the drawbacks of battery technology in embedded sensors, environmental energy is scavenged to power MEMS systems. Piezoelectric materials and electromagnetic set-ups are widely spread to transduce vibrations into electrical energy. This paper presents the merging of a piezoelectric with an electromagnetic transducer. The resulting hybrid energy generator shows a higher power density and an enhanced power output. Two power sources within one system feature different interconnection possibilities, and two different optimal load resistances.

<i>In vivo</i> generated human CAR T cells eradicate tumor cells (2019)

Chimeric antigen receptor (CAR) T cells are in prime focus of current research in cancer immunotherapy. Facilitating CAR T cell generation is among the top goals. We have recently demonstrated direct <i>in vivo</i> generation of human CD19-CAR T cells by targeting CD8<sup>+</sup> cells using lentiviral vectors (LVs). The anti-tumor potency of <i>in vivo</i> generated CAR T cells was assessed in human PBMC-transplanted NSG mice carrying i.v. injected CD19<sup>+</sup> Nalm-6 tumor cells. A single injection of CD8-targeted LV delivering CD19-CAR was sufficient to completely eliminate the tumor cells from bone marrow and spleen, whereas control animals contained high levels of CD19<sup>+</sup> cells. Tumor elimination was due to <i>in vivo</i> generated CAR<sup>+</sup> cells. Notably, these were not only composed of T lymphocytes but also included CAR<sup>+</sup> natural killer cells (NK and NKT). This is the first demonstration of tumor elimination by <i>in vivo</i> generated human CAR T cells.
Glucuronidation of bile acids under flow conditions: design of experiments and Koenigs–Knorr reaction optimization (2014)

An efficient method for the C3-glucuronidation of bile acids is developed under flow conditions. A modular mesoreactor assisted flow set-up was combined with statistical design of experiments to speed up the optimization of the Koenigs-Knorr reaction in terms of yield, regioselectivity, costs, as well as technical and practical standpoints. Using the optimal conditions, selective glucuronidation of naturally occurring bile acids was successfully achieved offering a new, valuable route to C3-glucuronidated bile acids useful for biological, diagnostic and PK/ADMET investigations.
Programs, life cycles, and laws of software evolution (1980)

By classifying programs according to their relationship to the environment in which they are executed, the paper identifies the sources of evolutionary pressure on computer applications and programs and shows why this results in a process of never ending maintenance activity. The resultant life cycle processes are then briefly discussed. The paper then introduces laws of Program Evolution that have been formulated following quantitative studies of the evolution of a number of different systems. Finally an example is provided of the application of Evolution Dynamics models to program release planning.
Nesting site density and distribution affect <i> <scp>O</scp> smia lignaria </i> ( <scp>H</scp> ymenoptera: <scp>M</scp> egachilidae) reproductive success and almond yield in a commercial orchard (2013)

Abstract The potential of commercially managed, native blue orchard bees, O smia lignaria , to augment honey bees in orchard pollination depends on various factors, particularly how to enhance O . lignaria retention while optimising even pollination throughout orchards by varying their stocking density and nesting site distribution. In 2011, we investigated how artificial nest box density and the number of cavities within nest boxes influenced O . lignaria retention and reproduction in a 61 ha almond orchard pollinated by a mixture of O . lignaria and Apis mellifera in the southern C entral V alley of C alifornia. We assessed how localised O . lignaria nesting affected total nut yield. Retention of O . lignaria females was significantly greater in orchard areas with high density nest boxes compared with areas with low density nest boxes. Females preferred to nest in high density (low cavity) nest boxes compared to low density (high cavity) nest boxes. All measures of O . lignaria reproductive success were greater in orchard areas with high density nest boxes than areas with low density nest boxes. Localised O . lignaria foraging and nesting activity influenced nut yield by producing more nuts in orchard areas with high density nest boxes compared with low density nest boxes, although differences in nut yield just failed to meet statistical significance. Results of this study show that the density and distribution of nest boxes for nesting O . lignaria females can strongly influence the reproductive success of an alternative, managed bee pollinator in a large production orchard.
Extracellular mucus and repair of superficial mucosal injury by restitution. (1989)

Release of mucus as a consequence of superficial injury to the gastric mucosa appears to play an important role in providing a microenvironment suitable for rapid re-epithelialization, or restitution, to occur. Evidence is presented in this paper to support this hypothesis. Firstly, disruption of the cap of mucus which forms over a site of damage, either mechanically or through the topical application of mucolytic agents, results in retardation of the restitution process. Secondly, the mucoid cap is shown to act as a trap to plasma released as a consequence of the damage. Thirdly, the mucoid cap provides a region of high pH (4 to 6), despite the presence in the lumen of a solution with a pH of 1.3. Based on the data presented in this report, and previous work from this laboratory and others, a functional model for extracellular mucus in promoting mucosal restitution is proposed.
Generation of single-nucleotide repair patches following excision of uracil residues from DNA. (1992)

The extent and location of DNA repair synthesis in a double-stranded oligonucleotide containing a single dUMP residue have been determined. Gently prepared Escherichia coli and mammalian cell extracts were employed for excision repair in vitro. The size of the resynthesized patch was estimated by restriction enzyme analysis of the repaired oligonucleotide. Following enzymatic digestion and denaturing gel electrophoresis, the extent of incorporation of radioactively labeled nucleotides in the vicinity of the lesion was determined by autoradiography. Cell extracts of E. coli and of human cell lines were shown to carry out repair mainly by replacing a single nucleotide. No significant repair replication on the 5' side of the lesion was observed. The data indicate that, after cleavage of the dUMP residue by uracil-DNA glycosylase and incision of the resultant apurinic-apyrimidinic site by an apurinic-apyrimidinic endonuclease activity, the excision step is catalyzed usually by a DNA deoxyribophosphodiesterase rather than by an exonuclease. Gap-filling and ligation complete the repair reaction. Experiments with enzyme inhibitors in mammalian cell extracts suggest that the repair replication step is catalyzed by DNA polymerase beta.
MHC-dependent cytolysis of autologous tumor cells by lymphocytes infiltrating urothelial carcinomas (1997)

Tumor-infiltrating lymphocytes (TIL) were grown from 23 urothelial carcinomas. Phenotyping analysis showed that the TIL cultures were mainly CD3+. Although CD4+ and CD8+ T-cell sub-sets were grown in culture, CD4+ T-cell sub-sets predominated over CD8+ T cells. Immunohistochemical studies performed on 5 tumor specimens confirmed this observation, and indicated that CD4+ T cells surrounded the tumor islets, whereas CD8+ T lymphocytes were localized among the tumor cells. Five short-term carcinoma cell lines established from these urothelial tumors were used as target cells in cytolysis assays in order to investigate the functional anti-tumor activity of autologous TIL. TIL from 4/5 tumors were lytic and 3 TIL lines displayed MHC-class-I-dependent cytotoxicity directed against autologous tumor cells. CD4+ T-cell-depletion experiments performed on TIL line 07 confirmed that CD8+ MHC-class-I-dependent CTL were the predominant effectors. Finally, experiments performed on 6 allogeneic urothelial-cancer cell lines matched for HLA-class-I molecules showed that TIL07 exhibited selective lytic activity toward tumor 07. These data indicate that CD8+ MHC-class-I-dependent CTL present in urothelial carcinomas are functional and may participate in the anti-tumor immune response.
An Argument against Athletes as Political Role Models (2017)

A common refrain in and outside academia is that prominent sports figures ought to engage more in the public discourse about political issues. This idea parallels the idea that athletes ought to be role models in general. This paper first examines and critiques the “athlete as role model” argument and then applies this critique to the “athlete as political activist” argument. Appealing to the empirical political psychological literature, the paper sketches an argument that athlete activism might actually do more harm than good.
