Universal quantum computation via quantum controlled classical operations
Authors: Horvat Sebastian , Gao Xiaoqin , Dakić Borivoje 
Published: December 2021

Abstract
A universal set of gates for (classical or quantum) computation is a set of gates that can be used to approximate any other operation. It is well known that a universal set for classical computation augmented with the Hadamard gate results in universal quantum computing. Motivated by the latter, we pose the following question: can one perform universal quantum computation by supplementing a set of classical gates with a quantum control, and a set of quantum gates operating solely on the latter? In this work we provide an affirmative answer to this question by considering a computational model that consists of 2n target bits together with a set of classical gates controlled by log (2n + 1) ancillary qubits. We show that this model is equivalent to a quantum computer operating on n qubits. Furthermore, we show that even a primitive computer that is capable of implementing only SWAP gates, can be lifted to universal quantum computing, if aided with an appropriate quantum control of logarithmic size. Our results thus exemplify the information processing power brought forth by the quantum control system.

Abstract
A mixture of Titanium and silicon-carbide powders was embedded in the AA5083 matrix by Friction Stir Processing (FSP). Experiments were performed as per Taguchi L8 orthogonal array, and the effect of reinforcement on hot strength (at 100 °C), processed zone (PZ) geometry, and microstructure were investigated. The effect of PZ geometry on the surface properties was also analyzed. The effect of heating the tensile test specimens to 540 °C on the strength at 100 °C was also separately investigated. It was observed that surface hardness was significantly enhanced by FSP, and the highest mean hardness of 90.4 HV was observed. Furthermore, it was observed that the surface properties also significantly depend on PZ geometry. From experimental results, it was found that the specimens with the lowest width to depth ratio bears the highest hardness and vice versa. A clear effect of parameters was evident on the geometry of processed zones with a deep bowl, and shallow cup-shaped zones were formed with smaller and larger shoulder diameters, respectively. The samples were processed at 355 rpm, 63 mm min−1, 17 mm shoulder, and 355 rpm, 80 mm min−1. The 20 mm shoulder showed high tensile strength 292 MPa and 294 Mpa, respectively. The strength of these samples did not reduce much even after heating to 540 °C.

Published: December 2021

Abstract
Acid fracturing is an effective technology for increasing oil and gas production. However, the acid will cause serious corrosion to the tubing. In this paper, the inhibition performance of the TG202 inhibitor for acidizing of high temperature and high-pressure gas wells on N80 carbon steel and 13Cr martensitic stainless-steel tubing in 15% hydrochloric acid was studied by electrochemical noise technology. The results showed that with the increase of TG202 inhibitor content, the noise resistance increased and the corrosion rate of tubing steel decreased. Under the same condition, the order of corrosion rate of tubing steels: 13Cr > HP-13Cr > N80 > P110. The pitting corrosion of HP-13Cr and 13Cr is significant. The research showed that the TG202 inhibitor had a protective effect on tubing during acidizing. The inhibition mechanism of the TG202 inhibitor was discussed.

Abstract
Doping superconductors are known to vary the superconducting transition temperature

depending on the degree of holes or electrons introduced in a system. In this study, we report how pressure-induced hole doping influences the

of GdBa2Cu3O7−x superconducting perovskite. The study was carried out in the framework of density functional theory (DFT) using the Quantum espresso code. Ultrasoft pseudopotential with generalized gradient approximation (GGA) functional was used to calculate the ground state energy using the plane waves (PW). The stability criterion was satisfied from the calculated elastic constants. The BCS theory and the Mc Millan’s equation was used to calculate the

Published: December 2021

Abstract
This paper reports the fabrication of an artificial synapse (AS) based on two-dimensional molybdenum disulfide (MoS2) film. The AS emulates important synaptic functions such as paired-pulse facilitation, spike-rate dependent plasticity, spike-duration dependent plasticity and spike-number dependent plasticity. The spike voltage can mediate ion migration in the ion gel to regulate the conductance of MoS2 channel, thereby realizing the emulation of synaptic plasticity. More importantly, the AS stably exhibits high sensitivity in response to spike stimuli (100 mV) and low-energy consumption (∼33.5 fJ per spike). In addition, the device emulates some synaptic functions and realizes the synaptic expression of Morse code. The development of this device represents an important step toward constructing high-performance and multifunctional neuromorphic system.
A reproducibility analysis-based statistical framework for residue–residue evolutionary coupling detection
Authors: Si Yunda , Zhang Yi , Yan Chengfei 
Published: December 2021

Abstract
Direct coupling analysis (DCA) has been widely used to infer evolutionary coupled residue pairs from the multiple sequence alignment (MSA) of homologous sequences. However, effectively selecting residue pairs with significant evolutionary couplings according to the result of DCA is a non-trivial task. In this study, we developed a general statistical framework for significant evolutionary coupling detection, referred to as irreproducible discovery rate (IDR)-DCA, which is based on reproducibility analysis of the coupling scores obtained from DCA on manually created MSA replicates. IDR-DCA was applied to select residue pairs for contact prediction for monomeric proteins, protein–protein interactions and monomeric RNAs, in which three different versions of DCA were applied. We demonstrated that with the application of IDR-DCA, the residue pairs selected using a universal threshold always yielded stable performance for contact prediction. Comparing with the application of carefully tuned coupling score cutoffs, IDR-DCA always showed better performance. The robustness of IDR-DCA was also supported through the MSA downsampling analysis. We further demonstrated the effectiveness of applying constraints obtained from residue pairs selected by IDR-DCA to assist RNA secondary structure prediction.

Abstract

Background
Despite the fact that emergency midline laparotomy is a risk factor for an incisional hernia, active research on hernia prevention in emergency settings is lacking. Different kinds of meshes and mesh positions have been studied in elective abdominal surgery, but no randomized controlled trials in emergency settings have been published thus far.

Method
The PREEMER trial (registration number NCT04311788) is a multicentre, patient- and assessor-blinded, randomized controlled trial to be conducted in six hospitals in Finland. A total of 244 patients will be randomized at a 1 : 1 ratio to either the retrorectus mesh group, featuring a self-gripping prophylactic mesh, or to the no mesh (control) group, both closed by small-stitch 4 : 1 closure with continuous slowly absorbable monofilament suturing. The primary outcome of the PREEMER trial is the incidence of incisional hernia 2 years after surgery, which will be detected clinically and/or radiologically. Secondary outcomes are the Comprehensive Complication Index score, incidence of surgical-site infections and fascial dehiscence within 30 days of surgery; the incisional hernia repair rate and mesh- or hernia-related reoperations within the 2- and 5-year follow-ups; the incidence of incisional hernia within the 5-year follow-up; and quality of life measured by RAND-36, the Activities Assessment Scale and the PROMIS questionnaire within 30 days and 2 and 5 years from surgery. Additionally, health–economic explorative measures will be explored.

Conclusion
The PREEMER trial will provide level 1 evidence on incisional hernia prevention in an emergency setting.

Evolution of Monetary Policy in Peru: An Empirical Application Using a Mixture Innovation TVP-VAR-SV Model
Authors: Portilla Jhonatan , Rodríguez Gabriel , Castillo B. Paul 
Published: December 2021

AbstractThis article discusses the evolution of monetary policy (MP) in Peru in 1996Q1–2019Q4 using a mixture innovation time-varying parameter vector autoregressive (VAR) model with stochastic volatility (TVP-VAR-SV) as proposed by Koop, Leon-Gonzales and Strachan. The main empirical results are: (i) the VAR coefficients and volatilities change more gradually than the contemporaneous coefficients over time; (ii) the volatility of MP shocks was higher under the pre-Inflation Targeting (IT) regime; (iii) a surprise increase in the interest rate produces gross domestic product (GDP) growth falls and reduces inflation in the long run; (iv) the interest rate reacts more quickly to aggregate supply shocks than to aggregate demand shocks; (v) MP shocks explain a high percentage of domestic variables behavior under the pre-IT regime but their contribution decreases under the IT regime. Overall, these results show that MP has contributed in Peru to lower macroeconomic volatility by (i) reducing average long-term inflation, (ii) increasing the response of GDP growth rate to interest rate, and (iii) by becoming more predictable.

The modularity of random graphs on the hyperbolic plane
Authors: Chellig Jordan , Fountoulakis Nikolaos , Skerman Fiona 
Published: December 2021

Abstract
Modularity is a quantity which has been introduced in the context of complex networks in order to quantify how close a network is to an ideal modular network in which the nodes form small interconnected communities that are joined together with relatively few edges. In this article, we consider this quantity on a probabilistic model of complex networks introduced by Krioukov et al. (2010, Phys. Rev. E, 82, 036106). This model views a complex network as an expression of hidden popularity hierarchies (i.e. nodes higher up in the hierarchies have more global reach), encapsulated by an underlying hyperbolic space. For certain parameters, this model was proved to have typical features that are observed in complex networks such as power law degree distribution, bounded average degree, clustering coefficient that is asymptotically bounded away from zero and ultra-small typical distances. In the present work, we investigate its modularity and we show that, in this regime, it converges to one in probability.
Legal: Use of Force in Self-Defence to Recover Occupied Territory
Authors: Akande Dapo , Tzanakopoulos Antonios 
Published: December 2021

Abstract
This article argues that, in certain circumstances, it is legal for a state to use force in self-defence in order to recover territory unlawfully occupied by another state as a result of an armed attack. Where occupation follows from an unlawful armed attack, the occupation is a continuing armed attack, and the attacked state does not lose its right to self-defence simply because of passage of time. It is argued that while it is trite law that territorial disputes cannot be resolved by recourse to force, it is important to draw the distinction between a territorial dispute, on the one hand, and a situation of armed attack resulting in occupation of territory, on the other. Furthermore, where years pass between the initial attack and the use of force in self-defence, that may suggest that there is no other reasonable means of bringing the armed attack and occupation to an end, rendering the use of force in self-defence the ultima ratio – which is precisely the point of the necessity requirement. On this view, time runs against, rather than in favour of, the aggressor.

Published: December 2021

Abstract

OBJECTIVES
The individualized thoracoscopic dorsal basal (S10) resection remains one of the most challenging procedures. Our goal was to detail the role of intersegmental veins (inter-SVs) in facilitating such a complex operation and evaluate its safety and efficacy.

METHODS
We retrospectively reviewed patients who underwent S10 or S10 plus an adjacent segment or subsegment resection (individualized S10) from January 2015 through September 2020. Individualized S10 resections were conducted for nodules of 2 cm or less with a ground-glass opacity evident in thin-slice computed tomography. A simplified method of using inter-SVs as the landmark in surgical planning and segmentectomy was described. The efficacy and safety of this technique were also evaluated in comparison with those aspects of the lower lobectomy.

RESULTS
In total, 46 patients who underwent individualized S10 through an inferior pulmonary ligament approach were included. All patients received R0 resection with a surgical margin of 22.45 mm. No patient was converted to an extended resection such as an entire basal or lower lobar resection. Three patients whose situation was complicated with an air leak had non-urgent interventions. Comparable results were obtained between the segmental and lobar arms in terms of blood loss (49.13 vs 45.98 ml), postoperative hospital stay (4.96 vs 5.18 days) and persistent air leak (6.52% vs 4.01%).

CONCLUSIONS
A strategy guided by the inter-SVs permits one to tailor the surgical planning for S10 nodules without compromising the surgical margin. It could also facilitate target bronchial recognition and intersegmental plane division. However, long-term follow-up and large clinical studies are needed to further justify its clinical benefits.

Abstract
We report the case of a 2-year-old girl with Loeys–Dietz syndrome complicated by aortic root dilatation and aortic regurgitation. We performed valve-sparing aortic root replacement with reimplantation technique and aortic valve repair using central plication and free-margin reinforcement simultaneously. The postoperative course was uneventful and the latest echocardiography, 5 years after procedure, revealed trivial aortic insufficiency.
Crime, Violence, and Political Participation
Authors: Boulding Carew , Mullenax Shawnna , Schauer Kathryn 
Published: December 2021

AbstractThe paper explores the relationship between crime victimization and political participation, making the argument that the observed (and oft-cited) relationship in surveys is the result of response bias. We show that people who are more extroverted, efficacious, and opinionated are more likely to respond positively to a question about victimization, and they are more likely to participate in politics. The implications of this finding are important and widespread—both for survey researchers interested in sensitive questions and for research on the relationship between crime and political engagement.

AbstractObjectivesLiterature assessing the optimal means of providing academic advisement in pharmacy education is limited. The objective of this study was to describe students’ perception of advising within a school of pharmacy.MethodsA 27-question survey was developed utilizing Qualtrics and sent to all students at one school of pharmacy. Baseline descriptive data regarding frequency and format of meeting with the assigned advisor were collected, as well as students’ opinions of these meetings.Key findingsOf 282 students who were sent the survey, 90 responded (31.9%). The majority of students preferred to meet with their faculty advisor in a group as compared with one-on-one (59 versus 29, 67%). Most students found the advisor/advisee relationship beneficial (n = 77, 85%).ConclusionsThere was no statistically significant difference in student perception of the quality or value of advisor/advisee meetings between students who met in a group or one-on-one with their advisors.
Ectopic uterus? A rare presentation of a giant leiomyoma in the posterior mediastinum

Published: December 2021

Abstract
Leiomyomas are benign mesenchymal tumors derived from smooth muscles. Uterus is the commonest site of origin for leiomyomas; however, unusual growth patterns and locations have been reported posing diagnostic challenges, clinically and radiologically. Histological diagnosis remains the gold standard of diagnosis. Here, we present a 17-year-old female with a 3-month history of chest pain, cough, difficulty in breathing and chest tightness. Chest CT scan showed a 12.3 cm × 14.4 cm × 22.8 cm mass occupying the entire left posterior hemithorax. The patient underwent thoracotomy and recovered well after surgery. Histopathology of the excised specimen confirmed it to be leiomyoma. Despite its rarity, primary mediastinal leiomyoma should be considered in the differential diagnosis of an unexplained mediastinal mass. Its accurate pre-operative diagnosis is difficult. Respiratory compromise and risk of transformation to sarcoma mandate complete surgical resection for a definitive diagnosis and good prognosis.

Authors: Hammami Emna , Borgi Wijden El , Lakhal Fatma Ben , Salem Sarra Fekih , Neji Hend Ben , Gouider Emna 
Published: December 2021

Abstract
Factor VII (FVII) deficiency is the most common among all rare inherited bleeding disorders. However, acquired FVII deficiency (aFVIID) is uncommon. Only few cases in the literature have been reported. Herein, we present a case of an aFVIID associated with acute myeloid leukemia (AML), along with a literature review regarding this condition. A 50 year old Arab male patient was diagnosed with AML at the hematology department of our institution. At admission, coagulation tests showed a prolonged prothrombin time (PT) with a normal activated partial thromboplastin time (aPTT) and a slightly elevated fibrinogen level. Prothrombin complex coagulation factors dosing (PCCFD) revealed a decrease only in FVII levels. The patient, however, did not experience any bleeding. The evolution of the health of the patient was marked by a normalization of PT and FVII levels and complete remission.
A Case of Trimethoprim-Sulfamethoxazole-Induced Aseptic Meningitis Masquerading as Septic Shock

Published: December 2021

ABSTRACT
Trimethoprim-sulfamethoxazole-induced aseptic meningitis (TSIAM) is a rare adverse reaction to a commonly prescribed antibiotic. We describe a case of severe TSIAM which resembled septic shock. A 30-year-old male with relapsed Hodgkin’s lymphoma 25 days status post autologous stem cell transplant presented to our clinic for evaluation of trimethoprim-sulfamethoxazole (TMP-SMX) hypersensitivity. After review of patient’s history and records, we had a low suspicion for a TMP-SMX adverse reaction and conducted an oral challenge to one 160 mg/800 mg tab of TMP-SMX. Four hours later, the patient developed vomiting, lightheadedness, and disorientation with progression to rigors, fever, tachycardia, and hypotension. He was admitted for fluid resuscitation and broad-spectrum antibiotic coverage for neutropenic fever and possible septic shock. A lumbar puncture performed due to complaints of headache, photophobia, and neck pain showed 375 white blood cells/µL with 73% neutrophil predominance, normal glucose (75 mg/dL), and elevated protein (101 mg/dL); additional cerebrospinal fluid (CSF) studies were negative for infectious etiologies. Fever and headache resolved by hospital day 4, at which time patient was discharged home. We believe this case represents TSIAM given the characteristic timing of symptom onset, CSF findings, and timing of symptom resolution without other clear etiology found on extensive infectious evaluation. It is important for allergists to recognize TSIAM, including its potential presentation as shock, in order to appropriately diagnose and counsel patients who seek evaluation for TMP-SMX adverse reactions.
