Most existing GP regression algorithms assume a single generative model, leading to poor performance when data are nonstationary, i.e. generated from multiple switching processes. Existing methods for GP regression over non-stationary data include clustering and changepoint detection algorithms. However, these methods require significant computation, do not come with provable guarantees on corr...

We generalize Rota's theorem characterizing the Mobius function of a geometric lattice in terms of subsets of atoms containing no broken circuit and give applications to the weak Bruhat order of a nite Coxeter group and the Tamari lattices. We also give a direct proof of the fact that in the geometric case any total order of the atoms can be used. Simple involutions are used in both proofs. Fi...

Abstract Directed energy deposition (DED) was used to produce niobium carbide (NbC)‐reinforced Ti6Al4V (Ti64) metal–matrix‐composite (MMC) structures. The objective improve upon Ti64's wear and oxidation resistance. characterization techniques consisted of scanning electron microscopy (SEM), backscattered (BSE) imaging, energy‐dispersive X‐ray spectroscopy (EDS), diffraction analysis (XRD), the...

Salah satu permasalahan yang dihadapi institusi perguruan tinggi adalah tidak tepatnya waktu kelulusan mahasiswa. Setiap tahunnya, jumlah mahasiswa mendaftar sebanding dengan lulusannya. Hal tersebut menjadi tugas program studi dalam memantau akademik mahasiswanya. Program perlu memiliki acuan untuk mengantisipasi berpotensi lulus tepat waktu. Dewasa ini, banyak sekali metode menyelesaikan berb...

Homeostasis of intracellular pH (pHi) has a crucial role for the maintenance of cellular function. Several membrane transporters such as lactate/H(+) cotransporter (MCT), Na(+)/H(+) exchange transporter (NHE), and Na(+)/HCO3 (-) cotransporter (NBC) are thought to contribute to pHi regulation. However, the relative importance of each of these membrane transporters to the in vivo recovery from th...
