Controlling the morphology of semiconductor na.ocrysta.s ha. typica.ly relied on controlling the concentra.ion a.d species of surfa.e liga.ds utilized in synthesis. Specific sha.es, such a. bra.ched structures a.e of pa.ticula. interest a. the light ha.vesting a.d cha.ge sepa.a.ing la.er in a.photovolta.c device. In this work we qua.tify how cha.ges in the rea.tion tempera.ure a.fect the resulting morphology of the na.ocrysta.s. The na.rowness of the tempera.ure ra.ge over which the morphologica. tra.sition occurred provides guida.ce to the tolera.ces necessa.y in the synthesis of CdSe utilized in commercia. devices on a.la.ge sca.e.

Ma.hema.ica. models ca. be very useful for understa.ding complica.ed systems, a.d for testing a.gorithms through simula.ion tha. would be difficult or expensive to implement. This pa.er describes the proposa. for a.model tha. would simula.e the sound loca.iza.ion performa.ce of profoundly hea.ing-impa.red persons using bila.era. cochlea. impla.ts (CIs). The expecta.ion is tha. this model could be used a. a.tool tha. could prove useful in developing new signa. processing a.gorithms for neura. encoding stra.egies. The hea. rela.ed tra.sfer function (HRTF) is a.critica. component of this model, a.d provides the ba.e cha.a.teristics of hea. sha.ow, torso a.d pinna.effects. This defines the tempora., intensity a.d spectra. cues tha. a.e importa.t to sound loca.iza.ion. This model wa. first developed to simula.e norma. hea.ing persons a.d va.ida.ed a.a.nst published litera.ure on HRTFs a.d loca.iza.ion. The model wa. then further developed to a.count for the differences in the signa. pa.hwa. of the CI user due to sound processing effects, a.d the microphone loca.ion versus ea. ca.a. a.oustics. Fina.ly, the loca.iza.ion error ca.cula.ed from the model for CI users wa. compa.ed to published loca.iza.ion da.a.obta.ned from this popula.ion.

With the election of Dona.d Trump a. President of the United Sta.es of a.erica. it a.pea.s likely tha. the initia.ion of mitiga.ion of huma.-ca.sed Globa.-Wa.ming/Clima.e-Cha.ge will be dela.ed ma.y yea.s. a.cordingly, here we ca.cula.e the Emission Pha.eout Dura.ion, D = YE - YS, where YS a.d YE a.e the Sta.t a.d End Yea.s of the emissions reduction, for YS = 2020, 2025 a.d 2030, a.d ma.imum Globa. Wa.ming ta.gets, ΔTma. = 2.0°C, 1.9°C, 1.8°C, 1.7°C, 1.6°C a.d 1.5°C. The 2.0°C a.d 1.5°C ma.ima.a.e the “Ha.d” a.d “a.pira.iona.” ta.gets of the 2015 Pa.is Clima.e a.reement. We find tha. D decrea.es with increa.ing YS from 2020, a.d with decrea.ing ΔTma.. In pa.ticula., D decrea.es from: 1) 76 yea.s for YS = 2020 to 53 yea.s for YS = 2030 for ΔTma. = 2.0°C, a.d 2) 34 yea.s for YS = 2020 to 7 yea.s for YS = 2030 for ΔTma. = 1.5°C. Thus, dela.ing the initia.ion of the pha.eout of greenhouse-ga. emissions from 2020 to 2030 ma.es it more difficult to a.hieve ΔTma. = 2.0°C a.d impossible to a.hieve ΔTma. = 1.5°C.
