This paper celebrates Professor Yon.qi GAO's sign.fican. achievemen. in.the field of in.erdisciplin.ry studies within.the con.ext of his fin.l research project Arctic Climate Prediction.: Pathways to Resilien. Sustain.ble Societies-ARCPATH(https://***/en.projects/fin.shed-projects/arcpath). The disciplin.s represen.ed in.the project are related to climatology, an.hropology, marin. biology, econ.mics, an. the broad spectrum of social-ecological studies. Team members were drawn.from the n.rdic coun.ries, Russia, Chin., the Un.ted States, an. Can.da. The project was tran.disciplin.ry as well as in.erdisciplin.ry as it in.luded collaboration.with local kn.wledge holders. ARCPATH made sign.fican. con.ribution. to Arctic research through an.improved un.erstan.in. of the mechan.sms that drive climate variability in.the Arctic. In.tan.em with this research, a combin.tion.of historical in.estigation. an. social, econ.mic, an. marin. biological fieldwork was carried out for the project study areas of Icelan., Green.an., n.rway, an. the surroun.in. seas, with a focus on.the join. use of ocean.an. sea-ice data as well as social-ecological drivers. ARCPATH was able to provide an.improved framework for predictin. the n.ar-term variation.of Arctic climate on.spatial scales relevan. to society, as well as evaluatin. possible related chan.es in.socioecon.mic realms. In.summary, through the in.egration.of in.ormation.from several differen. disciplin.s an. research approaches, ARCPATH served to create n.w an. valuable kn.wledge on.crucial issues, thus providin. n.w pathways to action.for Arctic commun.ties.

The Cap Pushin. Respon.e (CPR) is a free-flyin. techn.que used to study learn.n. an. memory in.hon.y bees (Apis mellifera). The series of experimen.s outlin.d in.this paper aimed to test whether hon.y bees exhibit the cogn.tive con.ept of “expectan.y” utilizin. the CPR in.a weight differen.iation.paradigm. Five previous experimen.s in.our laboratory have explored whether the con.ept of expectan.y can.accoun. for hon.y bee performan.e an. have all failed to support the cogn.tive in.erpretation. The first experimen. examin.d if bees could differen.iate between.the two caps in.the amoun. of force they used to push the cap an. the distan.e the cap was pushed when.the caps were presen.ed on. at a time. The secon. experimen. explored cap weight preferen.e by presen.in. bees with a choice between.the two caps. The third an. fourth experimen.s tested the bee’s ability to expect reward or pun.shmen. based on.cap weight. Results revealed that bees were foun. to have a stron. preferen.e for the light cap an. therefore were n.t able to expect reward or pun.shmen. based on.cap weight. These experimen.s con.ribute to the debate on.whether bees have “cogn.tive” represen.ation. an. con.in.e to support the behaviorist in.erpretation.

Purpose: Fraction.ted stereotactic radiosurgery (FSRS) can.be given.with at least three modalities: Gamma Kn.fe, with the n.n.n.asive frameless exten. system (GKE);lin.ar accelerator-based volumetric modulated arc therapy (VMAT);an. in.en.ity-modulated proton.therapy (IMPT). We extracted treatmen. plan. for patien.s who had received FSRS with GKE for recurren. skull base or in.racran.al tumors, created correspon.in. plan. for VMAT an. IMPT, an. compared the quality of the three sets of plan.. Methods an. materials: Plan. were extracted for 9 patien.s with recurren. malign.n. skull-base tumors (n.= 6) or large in.racran.al tumors (n.= 3) who had received FSRS with GKE (median.dose 24 Gy in.3 fraction.) in.2013 through 2015. Plan. for VMAT were gen.rated with a TrueBeam STx LIn.C machin. usin. 6-MV photon., an. plan. for IMPT were gen.rated with multi-field optimization. The optimized VMAT an. IMPT plan. were n.rmalized to achieve the best possible target coverage while meetin. the same dose-volume con.train.s on.organ. at risk (OARs) as the GKE plan.. Plan. were evaluated on.the basis of target coverage, con.ormity in.ex, homogen.ity in.ex, gradien. in.ex, an. treatmen. efficien.y. Results: The median.target volume was 10.2 cm3 (ran.e 1.9 - 33.8 cm3). The VMAT an. IMPT plan. met all OAR con.train.s, an. target coverage an. con.ormity were comparable amon. all plan.. VMAT an.

The GKE had superior high-dose gradien.s outside the target an. thus better protected surroun.in. n.rmal structures.

Peripheral n.rve in.uries in.uce a severe motor an. sen.ory deficit. Sin.e the availability of autologous n.rve tran.plan.s for n.rve repair is very limited, altern.tive treatmen. strategies are sought, in.ludin. the use of tubular n.rve guidan.e con.uits(tn.Cs). However, the use of tn.Cs results in.poor fun.tion.l recovery an. cen.ral n.crosis of the regen.ratin. tissue, which limits their application.to short n.rve lesion.defects(typically shorter than.3 cm). Given.the importan.e of vascularization.in.n.rve regen.ration. we hypothesized that en.blin. the growth of blood vessels from the surroun.in. tissue in.o the regen.ratin. n.rve within.the tn.C would help elimin.te n.crotic processes an. lead to improved regen.ration. In.this study, we reported the application.of macroscopic holes in.o the tubular walls of silk-based tn.Cs an. compared the various features of these improved silk^(+) tn.Cs with the tubes without holes(silk^(–) tn.Cs) an. autologous n.rve tran.plan.s in.an.8-mm sciatic n.rve defect in.rats. Usin. a combin.tion.of micro-computed tomography an. histological an.lyses, we were able to prove that the use of silk^(+) tn.Cs in.uced the growth of blood vessels from the adjacen. tissue to the in.ralumin.l n.ovascular formation.

In.the 15-mm(critical size) sciatic n.rve defect model, we again.observed a distin.t in.rowth of blood vessels through the tubular walls of silk^(+) tn.Cs, but without improved fun.tion.l recovery at 12 weeks postoperatively. Our data proves that macroporous tn.Cs in.rease the vascular supply of regen.ratin. n.rves an. facilitate improved axon.l regen.ration.in.a short-defect model but n.t in.a critical-size defect model.
