Meta Dynamic Pricing: Transfer Learning Across Experiments
Authors: Bastani Hamsa , Simchi-Levi David , Zhu Ruihao 
Published: September 2021

We study the problem of learning shared structure across a sequence of dynamic pricing experiments for related products. We consider a practical formulation in which the unknown demand parameters for each product come from an unknown distribution (prior) that is shared across products. We then propose a meta dynamic pricing algorithm that learns this prior online while solving a sequence of Thompson sampling pricing experiments (each with horizon T) for N different products. Our algorithm addresses two challenges: (i) balancing the need to learn the prior (meta-exploration) with the need to leverage the estimated prior to achieve good performance (meta-exploitation) and (ii) accounting for uncertainty in the estimated prior by appropriately “widening” the estimated prior as a function of its estimation error. We introduce a novel prior alignment technique to analyze the regret of Thompson sampling with a misspecified prior, which may be of independent interest. Unlike prior-independent approaches, our algorithm’s meta regret grows sublinearly in N, demonstrating that the price of an unknown prior in Thompson sampling can be negligible in experiment-rich environments (large N). Numerical experiments on synthetic and real auto loan data demonstrate that our algorithm significantly speeds up learning compared with prior-independent algorithms.

Inter-satellite laser-ranging based on intradyne coherent
detection
Authors: Zhu Funan , Lu Shaowen , Sun Jianfeng , Zhu Ren , Hou Xia , Chen Weibiao 
Published: September 2021

With the development of laser communication networking, laser-ranging technology is
becoming more and more applicable. In this paper, high-accuracy
ranging is implemented based on intradyne coherent detection at a
communication rate of 1048.576 Mbps. The ranging accuracy is affected
by clock phase calculation error and code loop track error. Parallel
clock phase difference calculation, frame head correlation, and
ranging ambiguity region handle are combined with the ranging
calibration method, realizing millimeter-level corrected distance
measurement. Dynamic range measurement above 1 m is proven to be
continuous through the ranging ambiguity region handle. In addition,
high-precision clock frequency deviation between two asynchronous
terminals can be obtained through derivation of one-way distance at
static ranging or by derivative of distance difference at
bidirectional ranging. The methods proposed in this paper are verified
by inter-satellite laser-ranging on orbit, and the results are
analyzed.

Considering various aspects such as the quality of the heterodyne correlation functions, the input information for data evaluation, and the line-broadening effects, both detection schemes show comparable overall efficiency.

The modeling of the influence of line broadening on the measurements results by a simple Gaussian-weighted sum of individual damped oscillations reveals the increasing complexity of the underlying wave vector distribution toward smaller wave vectors chosen for the scattering geometry.

Objective
To compare the effectiveness and safety of prescribing ibuprofen and oxycodone for at-home management of children’s fracture pain.

Methods
A prospective observational cohort was conducted at the Stollery Children’s Hospital pediatric emergency department (June 2010-July 2014). Children aged 4–16 years with an isolated fracture discharged home with advice to use either ibuprofen or oxycodone were recruited.

Results
A cohort of 329 children (n = 217 ibuprofen, n = 112 oxycodone) were included. Mean age was 11.1 years (SD 3.5); 68% (223/329) were male. Fracture distribution included 80.5% (264/329) upper limb with 34.3% (113/329) requiring fracture reduction. The mean reduction in Faces Pain Score-Revised score (maximum pain–post-treatment pain) for Day 1 was 3.6 (SD 1.9) (ibuprofen) and 3.8 (SD 2.1) (oxycodone) (p = 0.50); Day 2 was 3.6 (SD 1.8) (ibuprofen) and 3.7 (SD 1.6) (oxycodone) (p = 0.56); Day 3 was 3.7 (SD 1.7) (ibuprofen) and 3.3 (SD 1.7) (oxycodone) (p = 0.24). Children prescribed ibuprofen (51.2%, 109/213) experienced less adverse events compared to those prescribed oxycodone (70.5% 79/112) on Day 1 (p = 0.001). Children prescribed ibuprofen (71.8%, 150/209) had their function (eat, play, school, sleep) affected less than those prescribed oxycodone (83.0%, 93/112) (p = 0.03) on Day 1.

Conclusion
Children prescribed ibuprofen or oxycodone experienced similar analgesic effectiveness for at-home fracture pain. Oxycodone prescribing was associated with more adverse events and negatively impacted function. Oxycodone use does not appear to confer any benefit over ibuprofen for pain relief and has a negative adverse effect profile. Ibuprofen appears to be a safe option for fracture-related pain.

ObjectiveKawasaki disease (KD) is a systemic vasculitis in childhood that can lead to coronary artery lesions (CALs). Although early diagnosis and treatment is important for preventing KD patients from development of CALs, diagnosis depends on the clinical features of KD. We studied the usefulness of leucine-rich alpha-2-glycoprotein 1 (LRG1) and angiotensinogen (AGT), previously reported as KD-related proteins, for KD diagnosis and estimation of intravenous immunoglobulin (IVIG) efficacy.MethodsWe undertook a prospective cohort study with patients having two or more KD symptoms in multiple centers in Japan, between July 2017 and February 2019.ResultsTwo hundred forty-two patients were included. In multivariable analysis, one unit increase in LRG1 was associated with higher odds of KD diagnosis (Odds ratio [OR] 1.02 [95% confidence interval (CI) 1.001–1.03]). Double-positivity for AGT (≥ 26 μg/mL) and LRG1 (≥ 123.5 μg/mL) was an independent biomarker for KD diagnosis in both the total cohort and the subgroup of patients with two to four KD symptoms (OR 5.01 [95% CI 1.86–13.50] and 3.71 [95% CI 1.23–11.16], respectively). There was no association between LRG1/AGT and IVIG efficacy.ConclusionDouble-positivity for LRG1 and AGT is an biomarker for KD diagnosis, especially useful in diagnosing incomplete KD from non-KD. Future studies with larger cohorts should seek to determine whether LRG1 and AGT are valuable as definitive data referred at the diagnosis of KD and for estimating the risk of CALs.

INTRODUCTION:
Vulvar involvement is a rare complication of Crohn's disease (CD). The optimal treatment of vulvar CD is unknown.

METHODS:
We conducted a 25-year retrospective cohort study of vulvar CD from 3 referral centers. Clinical features and outcomes were studied.

RESULTS:
Fifty patients were identified. The most common vulvar symptoms were pain (74%), edema (60%), ulcerations (46%), nodules (36%), and abscess (34%). Medical management leading to symptomatic improvement varied, and 5 patients ultimately required surgery.

DISCUSSION:
Vulvar CD manifests with a broad spectrum of symptoms. Aggressive medical management was frequently effective, although surgery was required in 10% of cases.
Sustainable value of rice farm based on economic efficiency in Yogyakarta, Indonesia
Authors: Triyono  , Rahmawati Nur , Rozaki Zuhud 
Published: September 2021

AbstractAn analytical and integrated approach to farming needs to be formulated to assist decision-making by policymakers. This is important for the sustainability of agriculture in Indonesia, especially in the Special Region of Yogyakarta, which has experienced a decrease in land area, production, and productivity in the last 5 years. This study aims to analyze the sustainability of rice farming using the sustainable-value approach, which is based on the economically efficient use of agricultural resources. Data were collected from rice farmers in 25 observation areas attached to eight river irrigation sources throughout the province. A criterion for economic efficiency has been used as a guideline for setting benchmarks for optimal input use. The study reveals that, in general, these rice farms had poor economic productivity values. The sustainable value distribution for rice farms exceeded the highest value but there was low sustained quality. This indicates the limited overall longevity but also the potential for sustainability. Therefore, in managing rice farms, economic, social, and environmental resources have to be used more effectively.
Taking Responsibility for the Pasts
Authors: Larsen Svend Erik 
Published: September 2021

Abstract
One of the most significant connections between power and responsibility occurs in relation to the past. The post-revolutionary political powers of the new nations in the nineteenth century reinterpreted or, less politely formulated, invented their past to fit the process of nation building and only then take responsibility for future development of the nations. And they were not alone: pre-nineteenth century periods and the 20th and 21st centuries abound with examples. In our personal lives, self-empowerment often depends on the capacity to take responsibility for one’s past, including all its happy and traumatic moments. In a court room the forensic evidence of past events alone gives the judges the power to decide the fate of the defendant. In neither of the cases power and responsibility can work together without activating individual and collective memory and without finding a language to express responsibility as a manifestation of political, formal and personal power in a process of political legitimization, legal affirmation of justice and personal identity formation. With literary examples from South Africa this article discusses power and responsibility in their relation to a troubled political, legal and personal past.
“I Would Prefer Not To”: A Lawyer Facing the Irresponsible Power
Authors: Rossi Giuseppe 
Published: September 2021

Abstract
The essay considers Hermann Melville’s character Bartleby as an example of irresponsible power, since, in the story, the scrivener changes deeply his lawyer employer’s way of thinking and living, without giving any single answer to the many questions which the narrator keeps asking him about his apparently absurd behavior. The article offers some reflections about the difficulties that legal rules, as well as other set of rules (moral, ethics) meet when they are called to face irresponsible powers, and about the need to keep asking questions, though knowing that they will meet no final answers (thus accepting the irrationality of life, and coping with it).
The Power without Responsibility of the Gaze. The Letter and Spirit’s Eye in the Humanities, from the Italian Perspective to the Robot
Authors: Heritier Paolo 
Published: September 2021

Abstract
The paper identifies a continuity between the legal issue of the letter and spirit (or ratio) of the law and the invention of perspective as a symbolic form. The idea of perspective in Piero della Francesca’s Annunciation and the concept of “Italian perspective” in Arasse’s work are based on the aesthetic normativity of the painting in relation to the normative form of the norm, moving from the analysis of the invisible/visible nexus in legal theory. The notion of thirdness thus mediates between law as text and normativity as image, leading to the aesthetic enactment that conceives Italian playhouse as a form of theater, cinema, trial and university, as a symbolic form of knowledge and culture in the West. The simultaneously normative and aesthetic power of the gaze thus emerges as the removed from legal theory, until the problem of self-driving vehicles brings the issue back to the center of contemporary debate. The transition from frontal gaze to 360° vision suggests the theme of immersion as a new symbolic for the man–robot society.
“Shakespeare’s Pioneer Migrant Othello”: Desire, Migration, Pathology and the Politics of Citizenship in The Nature of Blood
Authors: Battisti Chiara 
Published: September 2021

Abstract
In a historical period characterised by political and social occurrences of immigration crises, Shakespeare’s and early modern dramatic attention to aliens and foreigners invite us to re-read the anguish of Shakespeare’s alien and to investigate the ways in which, in the specific case of Othello, the Moor’s experience prefigures subsequent migrations and the contemporary immigrants’ struggle for integration. Caryl Phillips’ creative re-appropriation of Shakespeare’s Othello in The Nature of Blood (1998) gives voice to the psychological anguish of a migrant in the guise of an unnamed Othello-like black general newly arrived in Venice. In a never-ending dialogue between present and past, Phillips articulates a complex reflection on the immigrants’ desire to be granted recognition as a legitimised individual with a social identity, while problematising the idea of home and the sense of belonging, here understood as the subjective feeling of identification with a city/nation. With such a complex redefinition in mind, my reading conceptualises Othello (alias the migrant) as an ethnopsychiatric “symptom”, in a psychopathology of migration and exile which exposes the meanings and practices of belonging produced and supported by host societies.
Performing Identities in Bram Stoker’s Dracula: The Encounter with the Other Between Politics, Tourism, Migration and Culture in the Late Victorian Context
Authors: Fiorato Sidia 
Published: September 2021

Abstract
Bram Stoker’s Dracula presents an investigation of identity from multiple perspectives: the political stance of the Victorian fin de siècle intersects with questions of identity and their liminal articulation through narrative control. The count becomes a “thick” synecdoche for the East and his arrival to England symbolises a reverse political and cultural colonisation that leads to a new image of the individual, revealing the innermost recesses of Western culture.

Published: September 2021

Abstract
In this work, diethylenetriamine pentamethylenephosphonic acid (DTPMP) was ultilized into preparing of Zr(IV) organophosphates hybrids (Zr-DTPMP-x, x was the molar ratio of Zr(IV)/DTPMP in the synthetic process, x = 0.5, 1, 2, and 3) using a hydrothermal method. The physical and chemical properties of Zr-DTPMP-x were characterized by SEM&EDS, FT-IR, XRD, Zeta potential, XPS, TGA and contact angle analysis. Moreover, the adsorptive performances of Zr-DTPMP-x for U(VI) were investigated. The adsorption results showed that the optimum molar ratio of Zr(IV) to phosphine, pH, equilibrium time, and dosage was 0.5, 4.0, 180 min, and 10 mg, respectively. Besides, the adsorption of U(VI) was in accordance with the pseudo-second-order kinetic model and Sips isothermal model. Moreover, the adsorption capacity determined by Sips isothermal model was 181.34 mg g−1 for Zr-DTPMP-0.5. Furthermore, the adsorptive selectivity of Zr-DTPMP-0.5 for U(VI) was superior than the others. Zr-DTPMP-0.5 may be a powerful candidate for diminishing the contamination of U(VI).
