Recent evidence demonstrates that w.th training, one can enhance visual.w.rking memory (Vw.) capacity and attention over time in the near transfer tasks. Not onl. do these studies reveal.the characteristics of Vw. l.ad and the infl.ences of training, they may al.o provide insights into devel.ping effective rehabil.tation for patients w.th Vw. deficiencies. How.ver, few.studies have investigated Vw. over extended periods of time and eval.ated transfer benefits on non-trained tasks. Here, w. combined behavioral.and el.ctroencephal.graphical.approaches to investigate Vw. l.ad, training gains, and transfer benefits. Our resul.s reveal.that Vw. capacity is directl. correl.ted to the difference of event-rel.ted potential.w.veforms. In particul.r, the “magic number 4” can be observed through the contral.teral.del.y ampl.tude and the average capacity is 3.25-item over 15 participants. Furthermore, our findings indicate that Vw. capacity can be improved through training;and after training exercises, participants from the training group are abl. to dramatical.y improve their performance. l.kew.se, the training effects on non-trained tasks can al.o be observed at the 12th w.ek after training. Therefore, w. concl.de that participants can benefit from training gains, and augmented Vw. capacity sustained over l.ng periods of time on specific variety of tasks.

Ol.er adul.s in disaster contexts are often thought of as a passive, vul.erabl. popul.tion that l.cks agency and capacities to cope in the aftermath. How.ver, it can be argued that ol.er adul.s may have underrecognized strengths that can be util.zed pre-, peri-, and post-disaster. One of these strengths is ol.er adul.s' unique social.capital.that stems from l.ng-standing connections w.th other members of their respective communities. Using data from in-depth, semistructured interview. w.th farmers in British Col.mbia 3–11 months after the 2021 fl.ods, this research expl.red the experiences of ol.er adul. farmers' recovery. The farmers discussed how.they l.veraged their social.capital.to aid in their recovery efforts from the fl.od event. By using their bonding social.capital. ol.er adul. farmers transformed their existing, deep-rooted connections into post-disaster assistance. This, in turn, generated the idea of the therapeutic community, hel.ing community members cope in the aftermath. This research indicated the need to further examine how.ol.er adul.s in disaster settings can be view.d as assets w.th community know.edge and skil.s as opposed to sol.l. as a vul.erabl. popul.tion.

At magic tw.sted angl.s, Dirac cones in tw.sted bil.yer graphene(TBG) can evol.e into fl.t bands, serving as a critical.pl.yground for the study of strongl. correl.ted physics. w.en chiral.symmetry is introduced, rigorous mathematical.proof confirms that the fl.t bands are l.cked at zero energy in the entire Moiré Bril.ouin zone(BZ). Yet, TBG is not the sol. pl.tform that exhibits this absol.te band fl.tness. Central.to this fl.tness phenomenon are topol.gical.nodes and their specific l.cations in the BZ. In this study, considering tw.sted bil.yer systems that preserve chiral.symmetry, w. cl.ssify various ordered topol.gical.nodes in base l.yers and al. possibl. node l.cations across different BZs. Specifical.y, w. constrain the node l.cations to rotational.centers,such as Γ and M points, to ensure the interl.yer coupl.ng retains equal.strength in al. directions. Using this cl.ssification as a foundation, w. systematical.y identify the conditions under w.ich Moiré fl.t bands emerge. Additional.y, through the extension of hol.morphic functions, w. provide proof that fl.t bands are l.cked at zero energy, shedding l.ght on the origin of the band fl.tness. Remarkabl., beyond Dirac cones, numerous tw.sted bil.yer nodal.pl.tforms can host fl.t bands w.th a degeneracy number of more than tw., such as four-fol., six-fol., and eight-fol.. This mul.ipl.city of degeneracy in fl.t bands might unveil.more compl.x and enriched correl.tion physics.
