Background: COVID-19 limitations have hindered the implementation of new technologies by preventing proctors from coming to the *** share our first experience of magnetic resonance imaging(MRI)-guided focused ultrasound(MRgFUS)treatment with an international remote online proctorship,and develop and evaluate the methodology of remote MRgFUS ***: This single-center,nonrandomized controlled prospective study included 94 patients:27 with essential tremor(ET)and 67 with tremor-dominant Parkinson's disease(PD).The coming of proctors was impossible,so we arranged for the remote participation of proctors from the United Kingdom,Spain,and Israel.A total of 38 patients(40.4%)received telemedicine-proctored treatment(proctor group)and 56 received their treatment independently(solo group).We used the Clinical Rating Scale for Tremor(CRST)for ET patients and the Unified Parkinson's Disease Rating Scale(UPDRS)Part III for PD ***: In patients with ET,success rates were 81.8%(proctor group)and 100%(solo group)(p=0.22).CRST reduction on the treated side was 71.43%[65.83%;80.56%](proctor group)versus 60.87%[53.99;79.58](solo group)(p=0.19).none of the patients showed worsening of tremors within 1 *** patients with PD,the success rates were 92.6%(proctor group)and 100%(solo group)(p=0.08).The UPDRS Part III improvement was 30.1%(proctor group)versus 39.9%(solo group)(p=0.003).The 1-year recurrence rate was 40%(proctor group)and 17.5%(solo group)(p=0.04).no complications were observed at 6 ***: We developed a feasible and safe methodology for telemedicine remote online-proctored MRgFUS *** significant difference was observed between the solo and developed remote proctor protocols in terms of complication rate,effect,and long-term results;however,UPDRS Part III improvement was better in the PD solo *** study demonstrated that the MRgFUS international proctorship can be performed successfully remotely.

For 0 〈 α 〈 mn and nonnegative integers n ≥ 2, m≥ 1, the multilinear fractional integral is defined bywhere →y= （y1, Y2,…, ym） and 7 denotes the m-tuple （f1, f2,…, fm）. In this note, the one- weighted and two-weighted boundedness on Lp （JRn） space for multilinear fractional integral operator I（am） and the fractional multi-sublinear maximal operator Mα（m） are established re- spectively. The authors also obtain two-weighted weak type estimate for the operator Mα（m）.

We have experimentally studied the ni/n-Si nano Schottky barrier height （SBH） and potential difference between patches in the nano Schottky diodes （SD） using contact atomic force microscopy （C-AFM） in tapping mode and scanning tunneling microscopy （STM）. Topology measurement of the surface with C-AFM showed that, a single ni/n-Si SD consists of many patches with different sizes. These patches are sets of parallel diodes and electrically interacting contacts of 5 to 50 nm sizes and between these individual diodes, there exists an additional electric field. In real metal semiconductor contacts （MSC）, patches with quite different configurations, various geometrical sizes and local work functions were randomly distributed on the surface of the metal. The direction and intensity of the additional electric field are distributed in homogenously along the contact metal surface. SBH controls the electronic transport across the MS interface and therefore, is of vital importance to the successful operation of semiconductor devices.

Let R = ⊙n〉0 Rn be a standard graded ring, a ∩ ⊙n〉0 Rn an ideal of R, and M, n two finitely generated graded R-modules. This paper studies the homogeneous components of graded generalized local cohomology modules. We show that for any i 〉 0, the n-th graded component Hiα（M, n）n of the i-th generalized local cohomology module of M and n with respect to a vanishes for all n 〉〉 0. Some sufficient conditions are pro- posed to satisfy the equality sup{end（Hiα （M, n）） [ i _〉 0} = sup{end（HiR＋（M, n））｜ i 〉 0}. Also, some sufficient conditions are proposed for the tameness of Hiα（M, n） such that i = fRα＋（M,n） or i = cdα（M,g）, where fRα＋（M,n） and cdα（M,g） denote the R＋- finiteness dimension and the cohomological dimension of M and n with respect to a, respectively. Finally, we consider the Artinian property of some submodules and quotient modules of Hjα（M, n）, where j is the first or last non-minimax level of Hiα（M, n）.
