Medical social workers’ values, views and practice regarding euthanasia
Creators: name: Marshall, Carolyn Louise
Publisher: name: University of British Columbia

description: Medical social workers from health care institutions in the urban lower mainland of British Columbia were asked about their views, values and practice regarding passive and active euthanasia. This qualitative, exploratory study focused on the attitudes, values and structures that influence professional social work practice with clients requesting euthanasia. During the months of August to November, 1994, seventeen medical social workers, who were experienced in this area, were interviewed. An interview guide format was used that was previously tested in a pilot study of this project. Within the pre-selected categories; views, values and practice, responses were described and emerging themes were identified through content analysis. The study results confirm medical social workers are playing an active professional role with terminally-ill patients, families and staff when requests are made for euthanasia in the health care system. In this study population, in most cases, the social worker's views, whether for or against euthanasia, did not determine his/her practice with patients. Instead, it was the social worker's willingness to give up his/her control in the patient/professional relationship in an effort to support the patient's decision to die with dignity. This practice was based on the value of patient self-determination being paramount against all other interests. Self-determination was ranked as the most influential factor in determining practice by most of the participants. Responses revealed there was a lack of understanding by health care professionals at all levels regarding the process of separating personal values from the professional obligation to respect patient self-determination. Feminist medical ethics suggests that all health care professionals need to engage in self-evaluation to address any need they may have for power and control in the professional/patient relationship. Furthermore, medical social workers should recognize their own such needs, particularly when their personal views and values come into conflict with a patient's decision regarding euthanasia. This study not only presents the issues of power and control that social workers and other health care professsionals experience in the medical system, it also explores and describes the contributions social workers have made in their practice with patients who request the right to die with dignity.

description: We study a class of stochastic processes of the type $\frac{d^n x}{dt^n}= v_0\, σ(t)$ where $n>0$ is a positive integer and $σ(t)=\pm 1$ represents an `active' telegraphic noise that flips from one state to the other with a constant rate $γ$. For $n=1$, it reduces to the standard run and tumble process for active particles in one dimension. This process can be analytically continued to any $n>0$ including non-integer values. We compute exactly the mean squared displacement at time $t$ for all $n>0$ and show that at late times while it grows as $\sim t^{2n-1}$ for $n>1/2$, it approaches a constant for $n<1/2$. In the marginal case $n=1/2$, it grows very slowly with time as $\sim \ln t$. Thus the process undergoes a {\em localisation} transition at $n=1/2$. We also show that the position distribution $p_n(x,t)$ remains time-dependent even at late times for $n\ge 1/2$, but approaches a stationary time-independent form for $n<1/2$. The tails of the position distribution at late times exhibit a large deviation form, $p_n(x,t)\sim \exp\left[-γ\, t\, Φ_n\left(\frac{x}{x^*(t)}\right)\right]$, where $x^*(t)= v_0\, t^n/Γ(n+1)$. We compute the rate function $Φ_n(z)$ analytically for all $n>0$ and also numerically using importance sampling methods, finding excellent agreement between them. For three special values $n=1$, $n=2$ and $n=1/2$ we compute the exact cumulant generating function of the position distribution at all times $t$.

description: We report on the generation of more than 5 dB of vacuum squeezed light at the Rubidium D1 line (795 nm) using periodically poled KTiOPO$_{4}$ (PPKTP) in an optical parametric oscillator. We demonstrate squeezing at low sideband frequencies, making this source of non-classical light compatible with bandwidth limited atom optics experiments. When PPKTP is operated as a parametric amplifier, we show a noise reduction of 4 dB stably locked within the 150 kHz-500 kHz frequency range. This matches the bandwidth of Electromagnetically Induced Transparency (EIT) in Rubidium hot vapour cells under the condition of large information delay.

description: Weakly Interacting Massive Particles (WIMPs) are one of the leading candidates for Dark Matter. We develop a model-independent method for determining the mass $m_χ$ of the WIMP by using data (i.e., measured recoil energies) of direct detection experiments. Our method is independent of the as yet unknown WIMP density near the Earth, of the form of the WIMP velocity distribution, as well as of the WIMP-nucleus cross section. However, it requires positive signals from at least two detectors with different target nuclei. In a background-free environment, $m_χ\sim 50$ GeV could in principle be determined with an error of $\sim 35%$ with only $2 \times 50$ events; in practice upper and lower limits on the recoil energy of signal events, imposed to reduce backgrounds, can increase the error. The method also loses precision if $m_χ$ significantly exceeds the mass of the heaviest target nucleus used.

description: This paper proposes a novel intrusion detection method for unmanned aerial vehicles (UAV) in the presence of recent actual UAV intrusion dataset. In particular, in the first stage of our method, we design an autoencoder architecture for effectively extracting important features, which are then fed into various machine learning models in the second stage for detecting and classifying attack types. To the best of our knowledge, this is the first attempt to propose such the autoencoder-based machine learning intrusion detection method for UAVs using actual dataset, while most of existing works only consider either simulated datasets or datasets irrelevant to UAV communications. Our experiment results show that the proposed method outperforms the baselines such as feature selection schemes in both binary and multi-class classification tasks.

description: We present Spitzer Space Telescope IRAC and MIPS observations of the galactic globular cluster M15 (NGC 7078), one of the most metal-poor clusters with a [Fe/H] = -2.4. Our Spitzer images reveal a population of dusty red giants near the cluster center, a previously detected planetary nebula (PN) designated K648, and a possible detection of the intra-cluster medium (ICM) arising from mass loss episodes from the evolved stellar population. Our analysis suggests 9 (+/-2) x 10^-4 solar masses of dust is present in the core of M15, and this material has accumulated over a period of approximately 10^6 years, a timescale ten times shorter than the last galactic plane crossing event. We also present Spitzer IRS follow up observations of K648, including the detection of the [NeII] 12.81 micron line, and discuss abundances derived from infrared fine structure lines.

description: We solve the ferromagnetic q-state Potts model on an inhomogeneous annealed network which mimics a random recursive graph. We find that this system has the inverted Berezinskii--Kosterlitz--Thouless (BKT) phase transition for any $q \geq 1$, including the values $q \geq 3$, where the Potts model normally shows a first order phase transition. We obtain the temperature dependences of the order parameter, specific heat, and susceptibility demonstrating features typical for the BKT transition. We show that in the entire normal phase, both the distribution of a linear response to an applied local field and the distribution of spin-spin correlations have a critical, i.e. power-law, form.

description: Micro-core architectures combine many low memory, low power computing cores together in a single package. These are attractive for use as accelerators but due to limited on-chip memory and multiple levels of memory hierarchy, the way in which programmers offload kernels needs to be carefully considered. In this paper we use Python as a vehicle for exploring the semantics and abstractions of higher level programming languages to support the offloading of computational kernels to these devices. By moving to a pass by reference model, along with leveraging memory kinds, we demonstrate the ability to easily and efficiently take advantage of multiple levels in the memory hierarchy, even ones that are not directly accessible to the micro-cores. Using a machine learning benchmark, we perform experiments on both Epiphany-III and MicroBlaze based micro-cores, demonstrating the ability to compute with data sets of arbitrarily large size. To provide context of our results, we explore the performance and power efficiency of these technologies, demonstrating that whilst these two micro-core technologies are competitive within their own embedded class of hardware, there is still a way to go to reach HPC class GPUs.

description: We study non-canonical relaxation in a composite cold atoms system, consisting of subsystems that possess negative microcanonical specific heat. The system exhibits pre-thermalization far away from integrability due to the appearance of a single adiabatic invariant. The Thirring instability drives the constituent subsystems towards the edges of their allowed energy spectrum, thus greatly enhancing the contrast between the prethermal state and the long time thermal outcome.

description: Low-cost reduced graphene oxide sponges functionalized with manganese oxide were used as electrodes for the disinfection of Escherichia coli in water. Manganese oxide was doped with amino groups MnxOyNH2 to strengthen the bond with the graphene coating and improve the electrochemical stability of the sponge. The Mn II and Mn III incorporated into the graphene coating favored the formation of oxygen vacancies and enhanced the electric and catalytic properties of the anode. Electrooxidation of real tap water at 29 A m2 resulted in 2.2 log removal of E. coli. After storing the treated samples for 18 h at 25 and 37 °C, the removal of E. coli increased to 3.3 and 4.6 log, respectively, demonstrating the irreparable damage to the bacterial cells via low-voltage electroporation, and the key role of storage temperature in their further inactivation. The energy consumption of the system treating real low conductivity tap water was 1.2-1.6 kWh m-3. Finally, experiments with intermittent current suggest the contribution of the pseudo-capacitance of the graphene sponge to electrochemical disinfection during the OFF periods. This study demonstrates the feasibility of manganese oxide-functionalized graphene sponges for the chlorine-free disinfection of water.

description: The tidal interaction between a disk and a planet leads to the planet's migration. A long-standing question regarding this mechanism is how to stop the migration before planets plunge into their central stars. In this paper, we propose a new, simple mechanism to significantly slow down planet migration, and test the possibility by using a hybrid numerical integrator to simulate the disk-planet interaction. The key component of the scenario is the role of low viscosity regions in protostellar disks known as dead zones, which affect planetary migration in two ways. First of all, it allows a smaller-mass planet to open a gap, and hence switch the faster type I migration to the slower type II migration. Secondly, a low viscosity slows down type II migration itself, because type II migration is directly proportional to the viscosity. We present numerical simulations of planetary migration by using a hybrid symplectic integrator-gas dynamics code. Assuming that the disk viscosity parameter inside the dead zone is (alpha=1e-4-1e-5), we find that, when a low-mass planet (e.g. 1-10 Earth masses) migrates from outside the dead zone, its migration is stopped due to the mass accumulation inside the dead zone. When a low-mass planet migrates from inside the dead zone, it opens a gap and slows down its migration. A massive planet like Jupiter, on the other hand, opens a gap and slows down inside the dead zone, independent of its initial orbital radius. The final orbital radius of a Jupiter mass planet depends on the dead zone's viscosity. For the range of alpha's noted above, this can vary anywhere from 7 AU, to an orbital radius of 0.1 AU that is characteristic of the hot Jupiters.

description: We present a solution to egocentric 3D body pose estimation from monocular images captured from downward looking fish-eye cameras installed on the rim of a head mounted VR device. This unusual viewpoint leads to images with unique visual appearance, with severe self-occlusions and perspective distortions that result in drastic differences in resolution between lower and upper body. We propose an encoder-decoder architecture with a novel multi-branch decoder designed to account for the varying uncertainty in 2D predictions. The quantitative evaluation, on synthetic and real-world datasets, shows that our strategy leads to substantial improvements in accuracy over state of the art egocentric approaches. To tackle the lack of labelled data we also introduced a large photo-realistic synthetic dataset. xR-EgoPose offers high quality renderings of people with diverse skintones, body shapes and clothing, performing a range of actions. Our experiments show that the high variability in our new synthetic training corpus leads to good generalization to real world footage and to state of theart results on real world datasets with ground truth. Moreover, an evaluation on the Human3.6M benchmark shows that the performance of our method is on par with top performing approaches on the more classic problem of 3D human pose from a third person viewpoint.

description: We discuss recent progress of understanding the phenomena observed in high Tc cuprates by studying the d-wave resonating-valence-bond (d-RVB) based trial wave functions for the 2-dimensional t-J-type models. Treat exactly the strong correlation between electrons by numerical approach, we examine the evolution of ground states described by different variational wave functions and properties of the quasi-hole and -particle excitations of the d-RVB superconducting (SC) state. Properties related to the Fermi surface geometry deduced from quasi-hole energy dispersion of the SC state is shown to be consistent with the observation by photoemission spectroscopy. With the calculated spectral weights (SW's) for adding and removing an electron, we found not only the anti-correlation between conductance peak height and width between peaks seen in tunneling experiments, but also unique properties due to strong correlation which need to be verified by future experiments.

Measuring correlated electron motion in atoms with the momentum-balance density

Year: 2020
Subjects: subject: Chemical Physics (physics.chem-ph)

description: Three new measures of relative electron motion are introduced: equimomentum, antimomentum, and momentum-balance. The equimomentum is the probability that two electrons have the exact same momentum, whereas the antimomentum is the probability their momenta are the exact opposite. Momentum-balance (MB) is the difference between the equimomentum and antimomentum, and therefore indicates if equal or opposite momentum is more probably in a system of electrons. The equimomentum, antimomentum and MB densities are also introduced, which are the local contribution to each quantity. The MB and MB density of the extrapolated-Full Configuration Interaction wave functions of atoms of the first three rows of the periodic table are analyzed, with a particular focus on contrasting the correlated motion of electrons with opposite and parallel spin. Coulomb correlation between opposite-spin electrons leads to a higher probability of equimomentum, whereas Fermi correlation between parallel-spin electrons leads to a higher probability of antimomentum. The local contribution to MB, given an electron is present, is a minimum at the nucleus and generally increases as the distance from the nucleus increases. There are also interesting similarities between the effects of Fermi correlation and Coulomb correlation (of opposite-spin electrons) on MB.

description: Το βακτηριακό σύστημα Escherichia coli αποτελεί ένα εύχρηστο και οικονομικό σύστημα παραγωγής ανασυνδυασμένων πρωτεϊνών με βιοτεχνολογική και φαρμακευτική σημασία. Παρόλα αυτά η συγκέντρωση των ετερόλογων πρωτεϊνών στα βακτηριακά έγκλειστα κατά την υπερέκφρασή τους στα βακτηριακά κύτταρα συνεχίζει να αποτελεί μείζον βιοτεχνολογικό πρόβλημα. Εκμεταλλευόμενοι τον φυσιολογικό ρόλο της μοριακής συνοδού DnaK στην πρωτεϊνική αναδίπλωση μελετήσαμε την συνεισφορά της στην in vivo διαλυτότητα και στην in vitro αναδίπλωση ενός τριπλού πρωτεϊνικού υβριδίου, IP10-DnaK-LUC. Το πρωτεϊνικό αυτό υβρίδιο περιλαμβάνει την χημειοκίνη IP10, την DnaK και την πρωτεΐνη-μάρτυρα, λουσιφεράση της πυγολαμπίδας (LUC), στο ίδιο πλαίσιο ανάγνωσης με μία ουρά έξι ιστιδινών στο καρβοξυτελικό άκρο. To σύνολο των αποτελεσμάτων μας αποδεικνύει ότι ένα τέτοιο πολλαπλό πρωτεϊνικό υβρίδιο, παρά το μέγεθός του, μπορεί να εμφανίσει υψηλή διαλυτότητα κατά την παραγωγή του στα E. coli, ειδικά κατά την συνέκφρασή του με τις co-chaperones της DnaK, τις DnaJ και GrpE. Επιπλέον, αποδείχθηκε ότι το υβρίδιο IP10-DnaK-LUC αναδιπλώνεται αποτελεσματικά in vitro, ιδιαίτερα παρουσία ATP, το οποίο ενεργοποιεί την δράση της DnaK ως μοριακή συνοδός. Ταυτόχρονα, στο υβρίδιο IP10-DnaK-LUC η περιοχή της IP10 φαίνεται να διατηρεί το χημειοτακτικό της ρόλο παρά την σύντηξή της με το υπόλοιπο πεπτίδιο.
description: The bacterium Escherichia coli is a convenient and economical system for producing recombinant proteins with biotechnological and pharmaceutical applications. The potential of E. coli as a protein «cell factory» is limited by the inability of many overproduced proteins to fold properly in bacterial cells and their subsequent accumulation in inclusion bodies. Taking advantage of the physiological role of the molecular chaperone DnaK in protein folding, we studied its contribution to the in vivo solubility and the in vitro refolding of a model triple hybrid protein, IP10-DnaK-LUC. This recombinant protein comprises the chemokine IP10, DnaK and a reporter enzyme, firefly luciferase (LUC), carrying a six-histidine tag at the carboxyl terminus. Our results demonstrate that this hybrid protein, despite its large size, can be produced in bacteria in a soluble form, especially when co-expressed with DnaJ and GrpE, the two DnaK co-chaperones. Furthermore, the chemically-denatured IP10-DnaK-LUC hybrid can refold efficiently in vitro, especially in the presence of ATP, which activates the molecular chaperone function of DnaK. The IP10-DnaK-LUC fusion was also found to be active in chemotaxis assays, indicating that the IP10 domain retains its chemoattractant function despite being fused to the rest of the protein.
Kasımalı Bayalinov'un "Acar" Adlı Hikâyesinde Göç

description: Göç; bireyin ekonomik, siyasi ve savaş gibi sebeplerle bir yerden başka bir yere mesken arayışıyla yola çıkmasıdır. Bu sebeplerin belki de en acımasız ve hazin olanı savaştır. Savaş, insanın canına, malına, milli ve manevi değerlerine zarar gelmesi neticesinde gönlünü kendi topraklarında bırakarak, elden başka çare gelmezcesine başka coğrafyalara yelken açmasına sebebiyet verebilecek, tesiri yüksek bir olaydır. Türkistan’da yeni bir Rusya yaratmayı hedefleyen ve bu hedef doğrultusunda Türkistan’da bölünmüş olan topraklara Rusları yerleştiren Çarlık rejimi, yerel halka ikinci sınıf gözüyle bakmış ve yerel halka ekonomik ve mülk açısından ciddi sıkıntılar yaşatmıştır. Halka uygulanan baskılar, insanların takatinin kırılmasına ve göç etmelerine yol açmıştır. Bu bağlamda yurtlarını geride bırakan insanlar, yeni bir dünyaya ulaşmak üzere yola çıkmışlardır. Ancak tasavvur edilen yeni bir dünya, geride bırakılan dünyadan daha iyi olmayacaktır. Kırgızistanlı yazar Kasımalı Bayalinov’un “Acar” adlı öyküsü, göçün insan ve hayat üzerine tesiri açısından önemli bir vesika niteliğindedir. “Acar”, Çağdaş Kırgız Edebiyatının sosyalist ve realist açıdan en başarılı nesir örneği kabul edilmektedir. Eser Kırgızca yazılmıştır ve ilk olarak 1928’de yayınlanmıştır. Kırgızlar, diğer Türkistan bölgesindeki Türk boyları gibi, tarih boyunca uzun ve badireli yollardan geçmişlerdir. 19. Yüzyılda Çarlık rejiminin yönetimi altında yaşamaya başlayan Kırgızlar, 1867 tarihinde Çarlık Rusyası’nın Türkistan’ı bölme niyetiyle karşı karşıya kalmışlardır. Bu niyetin ardı, Rusları o bölgelere yerleştirmek ve o topraklarla yeni Rusya oluşturmayı amaçlamaktır. Birinci Dünya Savaşı’na İtilaf Devletleri ile giren Rus Çarlığı, savaşta ciddi kayıplar vermesi sebebiyle Türkistan bölgesindeki Türkler silahaltına çağırılmıştır.  Bu çağrıyı reddeden Türkler, 1916 yılında ayaklanmaya başlamışlar ve Türkistan’ın diğer kısımlarına göç etmeye başlamışlardır. Türkler, Rus askerleri tarafından öldürülmeye başlanmıştır. Türklerin Ruslara direnişini ve mücadelesini gösteren bu olaya “Ürkün Olayı” denilmektedir. Bu çalışmada, Ürküm olayından yola çıkılarak ele alınan “Acar” adlı hikâye nezdinde göçün edebiyata yansımaları ele alınacaktır.

description: We report a compact, scalable, and high-performance superconducting nanowire single-photon detector (SNSPD) array by using a multichannel optical fiber array-coupled configuration. For single pixels with an active area of 18 um in diameter and illuminated at the telecom wavelength of 1550 nm, we achieved a pixel yield of 13/16 on one chip, an average system detection efficiency of 69% at a dark count rate of 160 cps, a minimum timing jitter of 74 ps, and a maximum count rate of ~40 Mcps. The optical crosstalk coefficient between adjacent channels is better than -60 dB. The performance of the fiber array-coupled detectors is comparable with a standalone detector coupled to a single fiber. Our method is promising for the development of scalable, high-performance, and high-yield SNSPDs.

description: A Cs fountain electron electric dipole moment (EDM) experiment using electric-field quantization is demonstrated. With magnetic fields reduced to 200 pT or less, the electric field lifts the degeneracy between hyperfine levels of different|mF| and, along with the slow beam and fountain geometry, suppresses systematics from motional magnetic fields. Transitions are induced and the atoms polarized and analyzed in field-free regions. The feasibility of reaching a sensitivity to an electron EDM of 2 x 10 exp(-50) C-m [1.3 x 10 exp(-29) e-cm] in a cesium fountain experiment is discussed.

description: We have learned to live with many potentially deadly viruses for which there is no vaccine, no immunity, and no cure. We do not live in constant fear of these viruses, instead, we have learned how to outsmart them and reduce the harm they cause. A new mathematical model that combines the spread of diseases that do not confer immunity together with the evolution of human behaviors indicates that we may be able to fight new diseases with the same type of strategy we use to fight viruses like HIV.

description: Πολλοί μαθητές παρουσιάζουν σημαντικές δυσκολίες στη μάθηση των μαθηματικών. Από την προσχολική ακόμη ηλικία τα παιδιά εμφανίζουν μεγάλες ατομικές διαφορές στις μαθηματικές τους γνώσεις και τις δεξιότητες. Οι μαθηματικές ικανότητες των μαθητών του νηπιαγωγείου αποδεικνύεται ένας ισχυρός παράγοντας πρόβλεψης για την μελλοντική τους μαθηματική επίδοση. Διάφορες μελέτες έχουν δείξει πως τα παιδιά με φτωχές μαθηματικές δεξιότητες στο νηπιαγωγείο βρίσκονται σε επικινδυνότητα να αναπτύξουν μεταγενέστερα σχολικές δυσκολίες. Πολλά παιδιά από την προσχολική ηλικία κατανοούν με ευκολία τις μαθηματικές έννοιες. Αυτό όμως δεν ισχύει για όλα τα παιδιά. Κάποια όχι μόνο μένουν πίσω σε σχέση με τους συνομηλίκους τους, αλλά ξεκινούν μια αρνητική πορεία στα μαθηματικά. Η έρευνα έχει δείξει πως το γνωστικό ύφος των παιδιών είναι μία έννοια-κλειδί που μπορεί να εξηγήσει αυτές τις ατομικές διαφορές. Ο σκοπός αυτής της εργασίας είναι να διερευνήσει την αποτελεσματικότητα ενός προγράμματος παρέμβασης που εφαρμόστηκε σε μαθητές νηπιαγωγείου που βρισκόταν σε επικινδυνότητα να εμφανίσουν σχολικές δυσκολίες στα μαθηματικά και να αξιολογήσει τον ρόλο της διδασκαλίας των αναλυτικών μεθόδων διδασκαλίας ως μέσο για την αντιμετώπιση των δυσκολιών στις αριθμητικές δεξιότητες.
description: Many students demonstrate significant difﬁculties in learning mathematics. By the preschool years, children demonstrate wide individual differences in their math ability and knowledge. Early math ability in kindergarten has proven to be a strong predictor of mathematical achievement. Several studies have shown that children with lower math abilities in kindergarten are at risk of difficulties in next years. Many children by the preschool years, have a solid understanding of math concepts. Not all children, however, develop this knowledge. Others children not only start behind their more advantaged peers, but also begin a negative trajectory in mathematics. Research has shown that children’s cognitive style is a key factor explaining these individual differences. The aim of this study is to test the effectiveness of an intervention program for kindergartners who were at risk for developing mathematics learning difficulties and to evaluate the role of instruction analytical processing methods as a means of facing of difficulties in arithmetic skills.
A third order BDF energy stable linear scheme for the no-slope-selection thin film model

description: In this paper we propose and analyze a (temporally) third order accurate backward differentiation formula (BDF) numerical scheme for the no-slope-selection (NSS) equation of the epitaxial thin film growth model, with Fourier pseudo-spectral discretization in space. The surface diffusion term is treated implicitly, while the nonlinear chemical potential is approximated by a third order explicit extrapolation formula for the sake of solvability. In addition, a third order accurate Douglas-Dupont regularization term, in the form of $-A Δt^2 Δ_N^2 ( u^{n+1} - u^n)$, is added in the numerical scheme. A careful energy stability estimate, combined with Fourier eigenvalue analysis, results in the energy stability in a modified version, and a theoretical justification of the coefficient $A$ becomes available. As a result of this energy stability analysis, a uniform in time bound of the numerical energy is obtained. And also, the optimal rate convergence analysis and error estimate are derived in details, in the $\ell^\infty (0,T; \ell^2) \cap \ell^2 (0,T; H_h^2)$ norm, with the help of a linearized estimate for the nonlinear error terms. %This convergence estimate is the first such result for a third order accurate scheme for a gradient flow. Some numerical simulation results are presented to demonstrate the efficiency of the numerical scheme and the third order convergence. The long time simulation results for $\varepsilon=0.02$ (up to $T=3 \times 10^5$) have indicated a logarithm law for the energy decay, as well as the power laws for growth of the surface roughness and the mound width. In particular, the power index for the surface roughness and the mound width growth, created by the third order numerical scheme, is more accurate than those produced by certain second order energy stable schemes in the existing literature.

description: We study current rectification effect in an asymmetric molecule HOOC-C$_6$H$_4$-(CH$_2$)$_n$ sandwiched between two Aluminum electrodes using an {\sl ab initio} nonequilibrium Green function method. The conductance of the system decreases exponentially with the increasing number $n$ of CH$_2$. The phenomenon of current rectification is observed such that a very small current appears at negative bias and a sharp negative differential resistance at a critical positive bias when $n\ge 2$. The rectification effect arises from the asymmetric structure of the molecule and the molecule-electrode couplings. A significant rectification ratio of $\sim$38 can be achieved when $n=5$.
