Sooner or Later? Promising Delivery Speed in Online Retail
Authors: Cui Ruomeng , Lu Zhikun , Sun Tianshu , Golden Joseph M. 
Published: August 2023

Abstract. Problem definition: Online retailers have to provide customers with an estimate of how fast an order can be delivered before they decide to make the purchase. Retailers can strategically adjust this delivery speed promise online without changing offline infrastructure, and doing so may fundamentally impact business outcomes. It can influence consumers’ purchasing decisions and postpurchase experiences, often in the opposite direction. On one hand, an aggressive (i.e., faster) delivery estimate could ensure that more customers meet their deadlines and thus, may increase their purchases ex ante. On the other hand, an aggressive estimate tends to overpromise, potentially leading to a longer than expected wait time, which can lower customer satisfaction and increase product returns ex post. In this research, we estimate the causal effect of retailers’ delivery speed promise on customer behaviors and business performance. Methodology/results: Collaborating with Collage.com , an online retailer that sells customized photo products across the United States, we exogenously varied the disclosed delivery speed estimates online while keeping the physical delivery speed unchanged. Using the difference-in-differences identification strategy, we find that a faster promise increases sales and profits, but it also increases product returns and reduces customer retention. In addition, we propose a data-driven model that uses the estimated parameters to optimize delivery promises to maximize customer lifetime value. Managerial implications: Our findings provide managerial insights and a data-driven policy that retailers can leverage to optimize and customize their delivery promises. Funding: T.

Published: August 2023

Telehealth has the potential to change the way we approach patient care. From virtual consenting to reducing carbon emissions, costs, and waiting times, it is a powerful tool in our clinical armamentarium. There is mounting evidence that remote diagnostic evaluation and decision-making have reached an acceptable level of accuracy and can safely be adopted in orthopaedic surgery. Furthermore, patients’ and surgeons’ satisfaction with virtual appointments are comparable to in-person consultations. Challenges to the widespread use of telehealth should, however, be acknowledged and include the cost of installation, training, maintenance, and accessibility. It is also vital that clinicians are conscious of the medicolegal and ethical considerations surrounding the medium and adhere strictly to the relevant data protection legislation and storage framework. It remains to be seen how organizations harness the full spectrum of the technology to facilitate effective patient care.Cite this article: Bone Joint J 2023;105-B(8):843–849.
SIRVA: Shoulder injury related to vaccine administration
Authors: Jenkins Paul J. , Duckworth Andrew D. 
Published: August 2023

Shoulder injury related to vaccine administration (SIRVA) is a prolonged episode of shoulder dysfunction that commences within 24 to 48 hours of a vaccination. Symptoms include a combination of shoulder pain, stiffness, and weakness. There has been a recent rapid increase in reported cases of SIRVA within the literature, particularly in adults, and is likely related to the mass vaccination programmes associated with COVID-19 and influenza. The pathophysiology is not certain, but placement of the vaccination in the subdeltoid bursa or other pericapsular tissue has been suggested to result in an inflammatory capsular process. It has been hypothesized that this is associated with a vaccine injection site that is “too high” and predisposes to the development of SIRVA. Nerve conduction studies are routinely normal, but further imaging can reveal deep-deltoid collections, rotator cuff tendinopathy and tears, or subacromial subdeltoid bursitis. However, all of these are common findings within a general asymptomatic population. Medicolegal claims in the UK, based on an incorrect injection site, are unlikely to meet the legal threshold to determine liability.Cite this article: Bone Joint J 2023;105-B(8):839–842.

Published: August 2023

AimsRotator cuff muscle atrophy and fatty infiltration affect the clinical outcomes of rotator cuff tear patients. However, there is no effective treatment for fatty infiltration at this time. High-intensity interval training (HIIT) helps to activate beige adipose tissue. The goal of this study was to test the role of HIIT in improving muscle quality in a rotator cuff tear model via the β3 adrenergic receptor (β3AR).MethodsThree-month-old C57BL/6 J mice underwent a unilateral rotator cuff injury procedure. Mice were forced to run on a treadmill with the HIIT programme during the first to sixth weeks or seventh to 12th weeks after tendon tear surgery. To study the role of β3AR, SR59230A, a selective β3AR antagonist, was administered to mice ten minutes before each exercise through intraperitoneal injection. Supraspinatus muscle, interscapular brown fat, and inguinal subcutaneous white fat were harvested at the end of the 12th week after tendon tear and analyzed biomechanically, histologically, and biochemically.ResultsHistological analysis of supraspinatus muscle showed that HIIT improved muscle atrophy, fatty infiltration, and contractile force compared to the no exercise group. In the HIIT groups, supraspinatus muscle, interscapular brown fat, and inguinal subcutaneous white fat showed increased expression of tyrosine hydroxylase and uncoupling protein 1, and upregulated the β3AR thermogenesis pathway. However, the effect of HIIT was not present in mice injected with SR59230A, suggesting that HIIT affected muscles via β3AR.ConclusionHIIT improved supraspinatus muscle quality and function after rotator cuff tears by activating systemic sympathetic nerve fibre near adipocytes and β3AR.Cite this article: Bone Joint Res 2023;12(8):455–466.

Published: August 2023

AimsThe burden of revision total hip arthroplasty (rTHA) continues to grow. The surgery is complex and associated with significant costs. Regional rTHA networks have been proposed to improve outcomes and to reduce re-revisions, and therefore costs. The aim of this study was to accurately quantify the cost and reimbursement for a rTHA service, and to assess the financial impact of case complexity at a tertiary referral centre within the NHS.MethodsA retrospective analysis of all revision hip procedures was performed at this centre over two consecutive financial years (2018 to 2020). Cases were classified according to the Revision Hip Complexity Classification (RHCC) and whether they were infected or non-infected. Patients with an American Society of Anesthesiologists (ASA) grade ≥ III or BMI ≥ 40 kg/m2 are considered “high risk” by the RHCC. Costs were calculated using the Patient Level Information and Costing System (PLICS), and remuneration based on Healthcare Resource Groups (HRG) data. The primary outcome was the financial difference between tariff and cost per patient episode.ResultsIn all, 199 revision episodes were identified in 168 patients: 25 (13%) least complex revisions (H1); 110 (55%) complex revisions (H2); and 64 (32%) most complex revisions (H3). Of the 199, 76 cases (38%) were due to infection, and 78 patients (39%) were “high risk”. Median length of stay increased significantly with case complexity from four days to six to eight days (p = 0.006) and for revisions performed for infection (9 days vs 5 days; p < 0.001). Cost per episode increased significantly between complexity groups (p < 0.001) and for infected revisions (p < 0.001). All groups demonstrated a mean deficit but this significantly increased with revision complexity (£97, £1,050, and £2,887 per case; p = 0.006) and for infected failure (£2,629 vs £635; p = 0.032). The total deficit to the NHS Trust over two years was £512,202.ConclusionCurrent NHS reimbursement for rTHA is inadequate and should be more closely aligned to complexity. An increase in the most complex rTHAs at major revision centres will likely place a greater financial burden on these units.Cite this article: Bone Jt Open 2023;4(8):559–566.

Published: August 2023

In inertial confinement fusion, high-precision x-ray imaging is crucial for understanding the states of matter under extreme conditions. To observe the target asymmetry during compression, multiple imaging spots with varying energy responses are necessary. However, integrating multiple imaging channels in a grazing incidence x-ray imaging scheme is challenging, and there is an urgent need for effective combination of multi-color and high-throughput diagnostics. This study presents a design method for a multi-channel integrated Wolter microscope with high spatial resolution, wide-band response, and high throughput. The basic optical configuration, adjustment method, and multi-channel integration scheme are discussed in detail. A 10 keV-class three-channel integrated Wolter microscope is proposed for verification, with an estimated spatial resolution better than 4.0 µm in a field of view of ±500µm. The peak response efficiencies for each imaging channel are calculated as 5.2×10−5sr, 8.6×10−5sr, and 2.2×10−4sr, respectively.

Published: August 2023

Accurate quality of transmission (QoT) estimations are essential enablers for future low-margin dynamic optical network operations. However, physical parameter measurement uncertainties and other intractable signal propagation effects degrade the accuracy of QoT estimation, especially in live production networks. The recent trend of network disaggregation further exacerbates the issue, and a vendor-agnostic accurate QoT estimator is much needed. In this paper, we study Gaussian-noise-model-based QoT estimation in a large-scale disaggregated and partially loaded live production network with monitored physical layer data spanning across 8 months. We first propose refining the signal power measurements by combining the inline amplifier and optical channel monitor (OCM) power measurements, followed by estimating the gain and noise power profiles of each inline amplifier, which in turn improves QoT estimation accuracy. We further introduce an optical multiplex section and frequency bias to the analytical model to incorporate intractable location-specific and spectral effects in the network and proposed data-driven parameter optimizations to learn the biases as well as erbium-doped fiber amplifier noise figures. The (mean, standard deviation) of the QoT estimation errors were reduced from (−0.1043, 0.6037) dB using average amplifier power and (−0.7875, 0.6337) dB using OCM power to (−0.0964, 0.4649) dB after input parameter refinements and were further reduced to (0.0046, 0.2377) dB with data-driven parameter optimization. The proposed methodologies are simple procedures that network operators can adopt to optimize analytical-model-based QoT estimators and/or serve as feature engineering procedures preceding machine-learning-based QoT in realistic disaggregated live production networks.

Published: August 2023

Background
Chronic subdural hematoma (CSDH) is commonly treated via surgical removal of the hematoma, placement of a routine indwelling drainage tube, and continuous drainage to ensure that the blood does not re-aggregate following removal. However, the optimal location for placement of the drainage tube remains to be determined.

Objectives
To aid in establishing a reference for selecting the optimal method, we compared the effects of different drainage tube placements on CSDH prognosis via a systematic review and meta-analysis of previous clinical studies.

Data sources
PubMed, Embase, and Cochrane databases.

Study eligibility criteria
We searched for clinical studies comparing the outcomes of subperiosteal/subgaleal drainage (SPGD) and subdural drainage (SDD) for CSDH published in English prior to April 1, 2022.

Participants
The final analysis included 15 studies involving 4,318 patients.

Results
Our analysis of the pooled results revealed no significant differences in recurrence rate between the SDD and SPGD groups. We also observed no significant differences in mortality or rates of postoperative complications (infection, pneumocephalus, or epilepsy) between the SDD and SPGD groups.

Conclusions
These results suggest that the choice of SDD vs. SPGD has no significant effect on CSDH prognosis, highlighting SPGD as an alternative treatment option for CSDH.
Notes on Two Amulets (Tyszkiewicz and de Serres) Inscribed with Sumerian Incantations
Authors: Bácskay András , Niederreiter Zoltán 
Published: August 2023

Abstract
This study supplements a previous paper that we published in this periodical: The Tyszkiewicz Amulet, a Chalcedony Pendant Inscribed with an Incantation on Thorn Bush: Notes on an Early Sumerian Kultmittelbeschwörung, AoF 46, 174–185. It compares the Tyszkiewicz amulet to another similar amulet formerly kept in the de Serres Collection and proposes that the two objects originate from the same workshop. Although the de Serres amulet bears a different incantation from the Udug-ḫul series, the two amulets are strikingly similar with regard to physical as well as textual aspects, the latter including the incorporation of certain ‘zi-litany’ sections.
Murder in Anatolia
Authors: de Ridder Jacob Jan , Kryszat Guido 
Published: August 2023

AbstractThis study presents an edition of a letter written by an Old Assyrian ruler (waklum) concerning the murder of several Anatolian locals at the hands of Assyrian merchants. The issue of financial compensation is taken up by the king of Assur, who acts on behalf of the City Assembly in Assur in solving the issue between the unnamed state from which the victims came and the accused Assyrian merchants. A case can be made that this letter is considerably younger than most of thewaklum-letters, though it cannot be ascribed to any ruler at present.
Tangential electrostatic field at metal surfaces
Authors: Huang Yuanjie 
Published: August 2023

AbstractIn electrodynamics, it has been long believed that when the electrostatic equilibrium is reached the electrostatic field outside a metal is always perpendicular to the metal surface. However, the tangential electrostatic field (TEF) may be discovered at the metal surface through the mechanical-electric coupling in the work. The TEF can lead to new knowledge and more accurate modification on electrostatics of metals including the electrostatic equilibrium conditions, uniqueness theorem, method of image charges, electrostatic shielding, Thompson’s theorem, and Green’s reciprocation theorem. The TEF and the mechanical-electric coupling can also indicate that an intrinsically intensive electrostatic field may exist at the nanoparticle surface. Thereby a unified model could be constructed for the surface-enhanced Raman scattering (SERS) which has been a long-standing problem in physics and chemistry in recent several decades. Furthermore, when the micro-electro-mechanical systems (MEMS) work, the deformation of the metal plate can induce an additional electrostatic field and a newly attractive electrostatic force between the metal plates. They may be important for the design and fabrication of high-performance MEMS devices. Overall, the revealed TEF may update the physical knowledge of the electrostatics of metals in electrodynamics and may acquire widespread applications in the areas of SERS, MEMS, and so on.

Published: August 2023

Abstract
Using recycled aggregates to prepare geopolymer concrete plays an essential role in reducing dependence on natural resources and solving the problem of waste accumulation. However, the application of geopolymer recycled aggregate concrete (GRC) has been greatly limited due to the defects in the quality of recycled aggregates and the limitations of the brittleness of concrete materials. Therefore, the work is dedicated to improving GRC properties and exploring the mechanism of action of steel fiber (SF) and nano-Al2O3. In this study, calcined gangue, slag, fly ash, and recycled aggregate were used as raw materials, the influence of SFs (0–1.25 vol%) was first explored by single factor analysis, and on this basis, the effect of nano-Al2O3 (NA) (0–2 wt%) on the GPC performance of SF was studied. The microstructure of GRC was analyzed by scanning electron microscopy. The test results showed that adding SF could significantly improve the splitting tensile and flexural strength of GRC, among which 0.75 vol% is the most excellent. However, the increase in compressive strength could be more apparent. The addition of NA can make up for the lack of SF in improving compressive performance. When NA content is 1 wt%, the version of GRC is most apparent. Adding 1% NA has the most significant advance in GRC performance. The microstructure analysis showed that the NA could promote the polymerization reaction, generate more gel, and make the contact interface between SF and matrix more compact, thus improving the strength of GRC.

Published: August 2023

AbstractSynaptic plasticity is a fundamental feature of the CNS that controls the magnitude of signal transmission between communicating cells. Many electrical synapses exhibit substantial plasticity that modulates the degree of coupling within groups of neurons, alters the fidelity of signal transmission, or even reconfigures functional circuits. In several known examples, such plasticity depends on calcium and is associated with neuronal activity. Calcium-driven signaling is known to promote potentiation of electrical synapses in fish Mauthner cells, mammalian retinal AII amacrine cells, and inferior olive neurons, and to promote depression in thalamic reticular neurons. To measure local calcium dynamicsin situ, we developed a transgenic mouse expressing a GCaMP calcium biosensor fused to Connexin 36 (Cx36) at electrical synapses. We examined the sources of calcium for activity-dependent plasticity in retina slices using confocal or Super-Resolution Radial Fluctuations imaging. More than half of Cx36-GCaMP gap junctions responded to puffs of glutamate with transient increases in fluorescence. The responses were strongly dependent on NMDA receptors, in keeping with known activity-dependent signaling in some amacrine cells. We also found that some responses depended on the activity of voltage-gated calcium channels, representing a previously unrecognized source of calcium to control retinal electrical synaptic plasticity. The high prevalence of calcium signals at electrical synapses in response to glutamate application indicates that a large fraction of electrical synapses has the potential to be regulated by neuronal activity. This provides a means to tune circuit connectivity dynamically based on local activity.

Tingginya penggunaan media sosial mendorong pergeseran aktivitas pengungkapan diri dari offline ke online. Padahal, perilaku pengungkapan diri online memiliki beragam risiko yang rentan dialami pengguna yang mayoritas berada di tahap perkembangan remaja dan dewasa awal. Penelitian ini bertujuan untuk mengetahui apakah ada perbedaan tingkat pengungkapan diri online di media sosial antara pengguna remaja dengan dewasa awal. Desain penelitian survei kuantitatif digunakan dengan convenience sampling sebagai teknik pengambilan sampel. Sebanyak 532 pengguna media sosial remaja dan dewasa awal, baik dari Pulau Jawa maupun dari luar Pulau Jawa terlibat dalam penelitian ini. Hasil analisis independent t-test menunjukkan tidak ada perbedaan yang signifikan pada pengungkapan diri online remaja dan dewasa awal. Akan tetapi, ditemukan perbedaan pengungkapan diri online ditinjau dari wilayah domisili dan durasi akses media sosial. Pengguna dari Pulau Jawa dan pengguna yang mengakses media sosial selama 6-8 jam perhari memiliki tingkat pengungkapan diri online yang lebih tinggi. Temuan ini memperkaya pemahaman mengenai perilaku pengguna media sosial di Indonesia. Masyarakat perlu berkolaborasi untuk mengelola perilaku bermedia sosial guna menghindari risiko penggunaan media sosial yang tidak terkontrol. The high use of social media encourages a shift in offline and online self-disclosure activities. Whereas online self-disclosure behavior has various risks that are prone to be experienced by users, most of whom are in the developmental stages of adolescence and early adulthood. This study aims to determine whether there is a difference in the level of online self-disclosure on social media between adolescent and early adult users. The quantitative survey research design was used with convenience sampling as the sampling technique. This research has 532 adolescent and early adult social media users, both from Java and outside Java, who were involved in this study. The results of the independent t-test analysis showed that there was no significant difference in online self-disclosure of adolescents and early adults. However, differences in online self-disclosure were found regarding the domicile area and duration of social media access. Users from Java and users accessing social media for 6-8 hours daily have higher online self-disclosure levels. These findings enrich the understanding of the behavior of social media users in Indonesia. Communities need to collaborate to manage social media behavior to avoid the risks of uncontrolled use of social media.
