Poems of Sheikh Muhammad al-Ghaly Ba
No full textThis volume contains seven poems handwritten by Muhammad al-Ghāli Ba. According to the author's son, Mountaga Ba, the poems were probably composed in the mid-1970s a time when the author lived in Mauritania, while working at the country's national radio station and serving as a special counsel to then president Moktar Ould Daddah (1924–2003). The poems adress various issues. The first is a call to action addressed to the Mauritianian youth, urging them to join in the collective work for the development of the country. The second poem is a hagiography on Ceerno Ahmad Nene Ba of Kaedi (Mauritania). The poem eulogizes the virtues of the patron. The third describes the event of Sharif Muhammad al-Habib's visit to the region of Fuuta region (Senegal), namely the village of Pate Galo. The fourth poem contains greetings and expresions of love addressed to the author's friends in the town of Kaedi. The fifth poem is a remembrance about good times. The author reminisces and praises the qualities of a woman named Jaari.The sixth poem describes one afternoon journey of the author.

Strongly coupled artificial bulk HTS grain boundaries with high critical current densities
No full textA multi-seeding process has been developed to fabricate single Y-Ba-Cu-O (YBCO) grains containing strong artificial grain boundaries. Multi-seeding of heterogeneous YBCO grains with controlled orientation was achieved using large Sm-Ba-Cu-O (SmBCO) single crystal seeds of rod-like geometry with slots of various widths (up to 13 mm) cut into their bottom surface (i.e. parallel to the c-axis of the seed) to produce a bridge-like structure. Several YBCO grains with artificial grain boundaries were fabricated from these seed crystals and used to investigate the effect of varying the distance between the individual grain nucleation sites and the grain orientation (in-plane and out of plane) on the nature of grain boundaries. The measured local magnetic critical current density (Jc) and the magnitude of the trapped field across these artificial grain boundaries indicate that seed alignment is a key parameter in achieving strongly-coupled grain boundaries in multi-seeded grains
Longitudinal analysis of serum neutralization of SARS-CoV-2 Omicron BA.2, BA.4, and BA.5 in patients receiving monoclonal antibodies
No full textThe emergence of Omicron sublineages impacts the therapeutic efficacy of anti-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) monoclonal antibodies (mAbs). Here, we evaluate neutralization and antibody-dependent cellular cytotoxicity (ADCC) activities of 6 therapeutic mAbs against Delta, BA.2, BA.4, and BA.5. The Omicron subvariants escape most antibodies but remain sensitive to bebtelovimab and cilgavimab. Consistent with their shared spike sequence, BA.4 and BA.5 display identical neutralization profiles. Sotrovimab is the most efficient at eliciting ADCC. We also analyze 121 sera from 40 immunocompromised individuals up to 6 months after infusion of Ronapreve (imdevimab + casirivimab) or Evusheld (cilgavimab + tixagevimab). Sera from Ronapreve-treated individuals do not neutralize Omicron subvariants. Evusheld-treated individuals neutralize BA.2 and BA.5, but titers are reduced. A longitudinal evaluation of sera from Evusheld-treated patients reveals a slow decay of mAb levels and neutralization, which is faster against BA.5. Our data shed light on antiviral activities of therapeutic mAbs and the duration of effectiveness of Evusheld pre-exposure prophylaxis
Boundary Algebra: A Simpler Approach to Boolean Algebra and the Sentential Connectives
No full textBoundary algebra [BA] is a algebra of type , and a simplified notation for Spencer-Brown’s (1969) primary algebra. The syntax of the primary arithmetic [PA] consists of two atoms, () and the blank page, concatenation, and enclosure between ‘(‘ and ‘)’, denoting the primitive notion of distinction. Inserting letters denoting, indifferently, the presence or absence of () into a PA formula yields a BA formula. The BA axioms are A1: ()()= (), and A2: “(()) [abbreviated ‘⊥’] may be written or erased at will,” implying (⊥)=(). The repeated application of A1 and A2 simplifies any PA formula to either () or ⊥. The basis for BA is B1: abc=bca (concatenation commutes & associates); B2, ⊥a=a (BA has a lower bound, ⊥); B3, (a)a=() (BA is a complemented lattice); and B4, (ba)a=(b)a (implies that BA is a distributive lattice). BA has two intended models: (1) the Boolean algebra 2 with base set B={(),⊥}, such that () ⇔ 1 [dually 0], (a) ⇔ a′, and ab ⇔ a∪b [a∩b]; and (2) sentential logic, such that () ⇔ true [false], (a) ⇔ ~a, and ab ⇔ a∨b [a∧b]. BA is a self-dual notation, facilitates a calculational style of proof, and simplifies clausal reasoning and Quine’s truth value analysis. BA resembles C.S. Peirce’s graphical logic, the symbolic logics of Leibniz and W.E. Johnson, the 2 notation of Byrne (1946), and the Boolean term schemata of Quine (1982).Boundary algebra; boundary logic; primary algebra; primary arithmetic; Boolean algebra; calculation proof; G.

Monitoring of the SARS-CoV-2 Omicron BA.1/BA.2 lineage transition in the Swedish population reveals increased viral RNA levels in BA.2 cases
No full textBACKGROUND: Throughout the SARS-CoV-2 pandemic, multiple waves of variants of concern have swept across populations, leading to a chain of new and yet more contagious variants dominating COVID-19 cases. Here, we tracked the remarkably rapid shift from Omicron BA.1 to BA.2 sublineage dominance in the Swedish population in early 2022 at a day-by-day basis. METHODS: Using a custom SARS-CoV-2 Omicron BA.1 lineage-typing RT-PCR assay, we analyzed 174,933 clinical upper airway samples collected during January to March 2022. FINDINGS: Our study demonstrates the feasibility and reliability of parallel lineage assignment of select variants at population scale, tracking the dominant sublineage transition from BA.1 to BA.2 at day-to-day resolution and uncovering nearly 2-fold higher levels of viral RNA in cases infected with Omicron BA.2 relative to BA.1. CONCLUSIONS: Our data provide unique insights into the Omicron BA.1 to BA.2 transition that occurred in Sweden during early 2022, and later, across the world. This may help to understand the increased transmissibility of the BA.2 variant

[[alternative]]A Pedagogical Grammar of the Chinese Disposal(Ba) Construction
No full text[[abstract]]Current pedagogical grammar of the Chinese disposal construction (ba) is based on Shou-hsin Teng’s theoretical framework and methodology in his A Pedagogical Grammar of Chinese (2003), which draws on 7,710 examples from a corpus of authentic material and theoretical linguistics/grammar research, and emphasizes the learner as a crucial parameter, providing an exhaustive description of the Chinese disposal construction. In my thesis, I identify three semantic functions of the Chinese disposal construction based on Teng’s theoretical framework: disposal, accidental, and causative. (The disposal semantic function comprises 94.53% of the 7,288 examples in the Academia Sinica Corpus.) Additionally, I seek to establish seven basic sub-structures of the disposal construction: ba 1) S ba OV + aspect; ba 2) S ba OV + result; ba 3) S ba OV + goal; ba 4) S ba OV + direction; ba 5) S ba OV + extent; ba 6) S ba OV + range; ba 7) S ba OV + reduplication.
Drawing on Teng’s principles regarding multiple sequences and the assessment of the difficulty grammar of points, I posit eight principles for assessing the difficulty of seven disposal construction sub-structures, and order such sub-structures according to their level of difficulty; in so doing, I assess the sequencing, pedagogical stages, and grading of the sub-structures, and create a model for disposal construction pedagogy which includes a series of computer-based, task-oriented scenarios. I believe my thesis can help bridge the gap between the fields of pedagogical grammar and pedagogy, and provide a discursive platform on which relevant issues can be further examined. Hopefully, my research and the potential discursive platform arising from it will lend themselves to discrediting the common belief that disposal construction pedagogy is best formulated according to an educator’s personal experiences. This thesis thereby situates the pedagogy of the disposal construction firmly in the realm of empirical science. Additionally, I seek to help educators to develop their pedagogical methodology according to my sequence of the disposal construction, and to systematically improve their teaching methods. In so doing, educators will enable second language learners not only to fully grasp the disposal construction and other related grammar points, but also to grasp the entirety of the Chinese grammar system. Thus they will ultimately allow learners to actively engage speakers of the target language in an appropriate, effective manner.
